+CHAPTER I--A SUSPICIOUS JEWELER
+
+
+“Well, Tom Swift, I don't believe you will make any mistake if you buy
+that diamond,” said the jeweler to a young man who was inspecting a tray
+of pins, set with the sparkling stones. “It is of the first water, and
+without a flaw.”
+
+“It certainly seems so, Mr. Track. I don't know much about diamonds, and
+I'm depending on you. But this one looks to be all right.”
+
+“Is it for yourself, Tom?”
+
+“Er--no--that is, not exactly,” and Tom Swift, the young inventor of
+airships and submarines, blushed slightly.
+
+“Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I think she
+would like a pin of this sort. True, it's rather expensive, but--”
+
+“No, it isn't for Mrs. Baggert, Mr. Track,” and Tom seemed a bit
+embarrassed.
+
+“No? Well, then, Tom--of course it's none of my affair, except to
+sell you a good stone, But if this brooch is for a young lady, I can't
+recommend anything nicer. Do you think you will take this; or do you
+prefer to look at some others?”
+
+“Oh, I think this will do, Mr. Track. I guess I'll take--”
+
+Tom's words were interrupted by a sudden action on the part of the
+jeweler. Mr. Track ran from behind the showcase and hastened toward the
+front door.
+
+“Did you see him, Tom?” he cried. “I wonder which way he went?”
+
+“Who?” asked the lad, following the shopkeeper.
+
+“That man. He's been walking up and down in front of my place for the
+last ten minutes--ever since you've been in here, in fact, and I don't
+like his looks.”
+
+“What did he do?”
+
+“Nothing much, except to stare in here as if he was sizing my place up.”
+
+“Sizing it up?”
+
+“Yes. Getting the lay of the land, so he or some confederate could
+commit a robbery, maybe.”
+
+“A robbery? Do you think that man was a thief?”
+
+“I don't know that he was, Tom, and yet a jeweler has to be always
+on the watch, and that isn't a joke, either, Tom Swift. Swindlers and
+thieves are always on the alert for a chance to rob a jewelry store, and
+they work many games.”
+
+“I didn't notice any particular man looking in here,” said Tom, who
+still held the diamond brooch in his hand.
+
+“Well I did,” went on the jeweler. “I happened to glance out of the
+window when you were looking at the pins, and I saw his eyes staring in
+here in a suspicious manner. He may have a confederate with him, and,
+when you're gone, one may come in, and pretend to want to look at some
+diamonds. Then, when I'm showing him some, the other man will enter,
+engage my attention, and the first man will slip out with a diamond ring
+or pin. It's often done.”
+
+“You seem to have it all worked out, Mr. Track,” observed the lad, with
+a smile. “How do you know but what I'm in with a gang of thieves, and
+that I'm only pretending to want to buy a diamond pin?”
+
+“Oh, I guess I haven't known you, Tom Swift, ever since you were
+big enough to toddle, not to be sure about what you're up to. But I
+certainly didn't like the looks of that man. However, let's forget about
+him. He seems to have gone down the street, and, after all, perhaps I
+was mistaken. Just wait until I show you a few more styles before you
+decide. The young lady may like one of these,” and the jeweler went to
+another showcase and took out some more trays of brooches.
+
+“What makes you think she's a young lady, Mr. Track?” asked the lad.
+
+“Oh, it's easy guessing, Tom. We jewelers are good readers of character.
+I can size up a young fellow coming in here to buy an engagement or a
+wedding ring, as soon as he enters the door. I suppose you'll soon be
+in the market for one of those, Tom, if all the reports I hear about you
+are true--you and a certain Mary Nestor.”
+
+“I--er--I think I don't care for any of these pins,” spoke Tom, quickly,
+with a blush. “I like the first lot best. I think I'll take the one I
+had in my hand when that man alarmed you. Ha! That's odd! What did I do
+with it?”
+
+Tom looked about on the showcase, and glanced down on the floor. He had
+mislaid the brooch, but the jeweler, with a laugh, lifted it out of a
+tray a moment later.
+
+“I saw you lay it down,” he said. “We jewelers have to be on the watch.
+Here it is. I'll just put it in a box, and--”
+
+With an exclamation, Mr. Track gave a hasty glance toward his big show
+window. Tom looked up, and saw a man's face peering in. At the sight of
+it, he, too, uttered a cry of surprise.
+
+The next instant the man outside knocked on the glass, apparently with
+a piece of metal, making a sharp sound. As soon as he heard it, the
+jeweler once more sprang from behind the showcase, and leaped for the
+door crying:
+
+“There's the thief! He's trying to cut a hole through my show window and
+reach in and get something! It's an old trick. I'll get the police! Tom,
+you stay here on guard!” and before the lad could utter a protest, the
+jeweler had opened the door, and was speeding down the street in the
+gathering darkness.
+
+Tom stared about him in some bewilderment. He was left alone in charge
+of a very valuable stock of jewelry, the owner of which was racing after
+a supposed thief, crying:
+
+“Police! Help! Thieves! Stop him, somebody!”
+
+“This is a queer go,” mused Tom. “I wonder who that man was? He looked
+like somebody I know, and yet I can't seem to place his face. I
+wonder if he was trying to rob the place? Maybe there's another one--a
+confederate--around here.”
+
+This thought rather alarmed Tom, so he went to the door, and looked up
+and down the street. He could see no suspicious characters, but in the
+direction in which the jeweler was running there was a little throng of
+people, following Mr. Track after the man who had knocked on the window.
+
+“I wish I was there, instead of here,” mused the lad. “Still I can't
+leave, or a thief might come in. Perhaps that was the game, and one of
+the gang is hanging around, hoping the store will be deserted, so he can
+enter and take what he likes.”
+
+Tom had read of such cases, and he at once resolved that he would not
+only remain in the jewelry shop, but that he would lock the door, which
+he at once proceeded to do. Then he breathed easier.
+
+The town of Shopton, in the outskirts of which Tom lived with his
+father, and where the scene above narrated took place, was none too well
+lighted at night, and the lad had his doubts about the jeweler catching
+the oddly-acting man, especially as the latter had a good start.
+
+“But some one may head him off,” reasoned Tom. “Though if they do catch
+him, I don't see what they can prove against him. Hello, here I am
+carrying this diamond pin around. I might lose it. Guess I'll put it
+back on the tray.”
+
+He replaced in the proper receptacle one of the pins he had been
+examining when the excitement occurred.
+
+“I wonder if Mary will like that?” he said, softly. “I hope she does.
+Perhaps it would be better if she could come here herself and pick out
+one--”
+
+Tom's musing was suddenly interrupted by a sharp tattoo on the glass
+door of the jewelry shop. With a start, he looked up, to see staring in
+on him the face of the man who had been there before--the man of whom
+the jeweler was even then in chase.
+
+“Why--why----” stammered Tom.
+
+The man knocked again.
+
+“Tom--Tom Swift!” he called. “Don't you know me?”
+
+“Know you--you?” repeated the lad.
+
+“Yes--don't you remember Earthquake Island--how we were nearly killed
+there--don't you remember Mr. Jenks?”
+
+“Mr. Jenks?”
+
+Tom was so startled that he could only repeat words after the strange
+man, who was talking to him from outside the glass door.
+
+“Yes, Mr. Jenks,” was the reply. “Mr. Barcoe Jenks, who makes diamonds.
+I saw you in the store about to buy a diamond--I wanted to tell you not
+to--I'll give you a better diamond than you can buy--I just arrived in
+this place--I must have a private talk with you--Come out--I'll share a
+wonderful secret with you.”
+
+A flood of memory came to Tom. He did recall the very strange man who
+walked around Earthquake Island--where Tom and some friends had been
+marooned recently--walked about with a pocketful of what he said were
+diamonds. Now Barcoe Jenks was here.
+
+“I must see you privately, Tom Swift,” went on Mr. Jenks, as he once
+more tapped on the glass. “Don't waste money buying diamonds, when you
+and I can make better ones. Where can I have a talk with you? I--” Mr.
+Jenks suddenly looked down the dimly-lighted street. “They're coming
+back!” he cried. “I don't want to be seen. I'll call at your house later
+to-night--be on the watch for me--until then--good-by!”
+
+He waved his hand, and was gone in an instant. Tom stood staring at the
+glass door. He hardly knew whether to believe it or not--perhaps it was
+all a dream.
+
+He pinched himself to make sure that he was awake. Very substantial
+flesh met his thumb and finger, and he felt the pain.
+
+“I'm awake all right,” he murmured. “But Barcoe Jenks here--and still
+talking that nonsense about his manufactured diamonds. I think he must
+be crazy. I wonder--”
+
+Once more the lad's musing was interrupted. He heard a murmur of excited
+voices outside the store, on the street. Then the door of the jewelry
+shop was tried. Mr. Track's face was pressed against the glass.
+
+“Open the door! Let me in, Tom!” he called. “I've caught the thief,” and
+as the lad unlocked the portal he saw that the jeweler held by the arm
+a ragged lad. “Ah; you scoundrel! I've caught you!” cried the diamond
+merchant, shaking the small chap, while Tom looked on, more mystified
+than ever.
+
+
+
+
+CHAPTER II--A MIDNIGHT VISIT
+
+
+While Mr. Track, the jeweler, and several citizens, attracted by the
+chase after the supposed thief, are crowded into the store, anxious to
+hear explanations of the strange affair, I will take the opportunity to
+tell you something of Tom Swift, the lad who is to figure in this story.
+
+Many of you have already made his acquaintance, when he has been
+speeding about in his airship or fast electric runabout, and to others
+we will state that our hero first made his bow to the public in the
+book called “Tom Swift and His Motor-Cycle,” the initial volume of this
+series.
+
+In that story there was related how Tom made the acquaintance of an
+odd individual, named Mr. Wakefield Damon, who was continually blessing
+himself, some part of his anatomy, or his possessions. Mr. Damon was
+riding a motor-cycle, and it started to climb a tree, to his pain and
+fright. Afterward Tom purchased the machine, and had many adventures
+on it, including a chase after a gang of men who had stolen a valuable
+patent model belonging to Mr. Swift.
+
+Mr. Swift and his son were both inventors. They lived together in a
+fine house in the suburbs of Shopton, New York, and with them dwelt Mrs.
+Baggert, the housekeeper (for Tom's mother was dead), and also Garret
+Jackson, an expert engineer, who aided the young inventor and his father
+in perfecting many machines.
+
+There was also another semi-member of the household, to wit, Eradicate
+Sampson, an eccentric colored man, who owned a mule called Boomerang.
+Eradicate did odd jobs around the place, and the mule assisted his
+owner--that is when the mule felt like it.
+
+In the second volume of the series, entitled “Tom Swift and His
+Motor-Boat,” there was related the incidents following a pursuit after
+a gang of unprincipled men, who sought to get possession of some of Mr.
+Swift's patents, and it was while in this boat that Tom, his father, and
+a friend, Ned Newton, rescued from Lake Carlopa a Mr. John Sharp, who
+fell from his burning balloon. Mr. Sharp was a skilled aeronaut, and
+after his recovery he joined Tom in building a big airship, called the
+Red Cloud. Tom's adventures in this craft are set down in detail in the
+third volume of the series, called “Tom Swift and His Airship.” Not only
+did he and Mr. Sharp and Mr. Damon make a great trip, but they captured
+some bank robbers, and incidentally cleared themselves from the
+imputation of having looted the vault of seventy-five thousand dollars,
+which charge was fostered by a certain Mr. Foger, and his son Andy, who
+was Tom's enemy.
+
+Not satisfied with having conquered the air, Tom and his father set
+to work to gain a victory over the ocean. They built a boat that could
+navigate under water, and, in the fourth book of the series, called “Tom
+Swift and His Submarine Boat,” you will find an account of how they went
+under the ocean to secure a sunken treasure, and the fight they had with
+their enemies who sought to get it away from them. They went through
+many perils, not the least of which was capture by a foreign warship.
+
+In the fifth book, entitled “Tom Swift and His Electric Runabout,” there
+was told the story of a wonderfully speedy electric automobile the young
+inventor constructed, and how he made a great race in it, and saved from
+ruin a bank, in which his father and Mr. Damon were interested.
+
+Tom's ability as an inventor had, by this time, become well known. One
+day, as related in a volume called “Tom Swift and His Wireless Message,”
+ he received a letter from a Mr. Hosmer Fenwick, of Philadelphia, asking
+his aid in perfecting an airship which the resident of the Quaker
+City had built, but which would not work. In his small monoplane, the
+Butterfly, Tom and Mr. Damon went to Philadelphia, as Mr. Damon was
+acquainted with Mr. Fenwick.
+
+Tom carefully inspected the Whizzer which was the name of Mr. Fenwick's
+airship, and, after some difficulties, succeeded in getting the electric
+craft in shape to make a flight.
+
+Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape May in the
+Whizzer, but were caught in a terrific storm, and blown out to sea.
+The wind became a hurricane, the airship was disabled, and wrecked in
+mid-air. When it fell to earth it landed on one of the small West Indian
+islands, but what was the terror of the three castaways to find that the
+island was subject to earthquake shocks.
+
+But the earth-tremors were not the only surprise in store for Tom and
+his two friends, On the island they found five men and two ladies, who,
+by strange chance, had been stranded there when the yacht Resolute,
+owned by Mr. George Hosbrook, was wrecked in the same storm that
+disabled the airship. Mr. Hosbrook, a millionaire, was taking a party of
+friends to the West Indies.
+
+When the castaways (among whom were Mr. and Mrs. Amos Nestor, parents
+of Mary Nestor, a girl of whom Tom was very fond) found that there was
+danger of the island being destroyed in an earthquake, they were in
+despair. There seemed no way of being rescued, as the island was out of
+the line of regular ship travel.
+
+Tom, however, was resourceful. With the electrical apparatus from the
+wrecked airship, he built a wireless plant, and sent messages for help,
+broadcast over the ocean.
+
+They were finally heard, and answered, by an operator on board the
+steamer Camberanian, which came on under forced draught, and rescued
+Tom and his friends. It was only just in time, for, no sooner had
+they gotten aboard the steamer in lifeboats, than the whole island was
+destroyed by an earthquake shock.
+
+But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the
+others, got safely home. Among the survivors from the yacht Resolute
+was a Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom
+through the glass window of the jewelry store. Mr. Jenks was a peculiar
+man. Tom discovered this on Earthquake Island. Mr. Jenks carried with
+him some stones which he said were diamonds. He asserted that he had
+made them, but Tom did not know whether or not to believe this.
+
+When it seemed that the castaways would not be saved Mr. Jenks offered
+Tom a large sum in these same diamonds for some plan whereby he might
+escape the earthquakes. Mr. Jenks said there was a certain secret in
+connection with the manufactured diamonds that he had to solve--that he
+had been defrauded of his rights--and that a certain Phantom Mountain
+figured in it. But Tom, at that time, paid little attention to Mr.
+Jenks' talk. The time was to come, however, when he would attach much
+importance to it.
+
+When this story opens, Tom was more interested in Mr. Barcoe Jenks than
+in any one else, and was wondering what he wanted to see him about. The
+young inventor could not quite understand how Mr. Track, the jeweler,
+could come back with a lad he suspected of being a thief, when the
+person who had acted so suspiciously, and who had knocked on the glass,
+was the queer man, Mr. Jenks.
+
+“Yes, Tom I caught him,” the jeweler went on. “I chased after him, and
+nabbed him. It was hard work, too, for I'm not a good runner. Now, you
+little rascal, tell me why you tried to rob my store?” and the diamond
+merchant shook the lad roughly.
+
+“I--I didn't try to rob your store,” was the timid answer.
+
+“Well, perhaps you didn't, exactly, but your confederates did. Why did
+you rap on the glass, and why were you staring in so intently?”
+
+“I wasn't lookin' in.”
+
+“Well, if it wasn't you, it was some one just like you. But why did you
+run when I raced down the street?”
+
+“I--I don't know,” and the lad began to snivel. “I--I jest ran--that's
+all--'cause I see everybody else runnin', an' I thought there was a
+fire.”
+
+“Ha! That's a likely story! You ran because you are guilty! I'm going to
+hand you over to the police.”
+
+“Did he get anything, Mr. Track?” asked one of the men who had joined
+the jeweler in the chase.
+
+“No, I can't say that he did. He didn't get a chance. Tom Swift was
+in here at the time. But this fellow was only waiting for a chance to
+steal, or else to aid his confederates.”
+
+“But, if he didn't take anything, I don't see how you can have him
+arrested,” went on the man.
+
+“On suspicion; that's how!” asserted Mr. Track. “Will some one get me a
+constable?”
+
+“I wouldn't call a constable,” said Tom, quietly.
+
+“Why not?”
+
+“Because that isn't the person who looked in your window.”
+
+“How do you know, Tom?”
+
+“Because that person came back while you were out. I saw him.”
+
+“You saw him? Did he try to steal any of my diamonds, Tom?”
+
+“No, I guess he doesn't need any.”
+
+“Why not?” There was wonder in the jeweler's tone.
+
+“Why, he claims he can make all he wants.”
+
+“Make diamonds?”
+
+“So he says.”
+
+“Why, he must be crazy!” and Mr. Track laughed.
+
+“Perhaps he is,” admitted Tom, “I'm only telling you what he says. He's
+the person who acted so suspiciously. He came back here, I'm telling
+you, while you were running down the street, and spoke to me.”
+
+“Oh, then you know him?” The jeweler's voice was suspicious.
+
+“I didn't at first,” admitted Tom. “But when he said he was Mr.
+Barcoe Jenks, I remembered that I had met him when I was cast away on
+Earthquake Island.”
+
+“And he says he can make diamonds?” asked Mr. Track.
+
+“What did he want of you?” and the jeweler looked at Tom, quizzically.
+
+“He wanted to have a talk with me,” replied the lad, “and when he saw
+me in your store, he tried to attract my attention by knocking on the
+glass.”
+
+“That's a queer way to do,” declared Mr. Track. “What did he want?”
+
+“I don't know exactly,” answered Tom, not caring to go into details just
+then. “But I'm sure, Mr. Track, that you've got the wrong person there.
+That lad never looked in the window, nor knocked on the glass.”
+
+“That's right--I didn't,” asserted the captive.
+
+The jeweler looked doubtful.
+
+“Why did you run?” he asked.
+
+“I told you, I thought there was a fire.”
+
+“That's right, I don't believe he's the fellow you want,” put in another
+man. “I was standing on the corner, near White's grocery store, and
+I noticed this lad. That was before I heard you yelling, and saw you
+coming, and then I joined in the chase. I guess the man you were after
+got away, Track.”
+
+“He did,” asserted Tom. “He came back here, a little while ago, and he
+ran away just now, as he heard you coming.”
+
+“Where did he go?” asked the jeweler, eagerly.
+
+“I don't know,” answered Tom. “Only you've got the wrong lad here.”
+
+“Well, perhaps I have,” admitted the diamond merchant. “You can go,
+youngster, but next time, don't run if you're not guilty.”
+
+“I thought there was a fire,” repeated the lad, as he hurriedly slipped
+through the crowd in the store, and disappeared down the dark street.
+
+“Well, I guess the excitement's all over, and, anyhow, you weren't
+robbed, Track,” said a stout man, as he left the store. The others soon
+followed, and Tom and the jeweler were once more alone in the shop.
+
+“Can you tell me something about this man, Tom?” asked Mr. Track,
+eagerly. “So he really makes diamonds. Who is he?”
+
+“I'd rather not tell--just now,” replied the young inventor. “I don't
+take much stock in him, myself. I think he's visionary. He may think he
+has made diamonds, and he may have made some stones that look like them.
+I'm very skeptical.”
+
+“If you could bring me some, Tom, I could soon tell whether they were
+real or not. Can you?”
+
+The lad shook his head.
+
+“I don't expect to see Mr. Jenks again,” he said. “He talked
+rather wildly about waiting to meet me, but that man is odd--crazy,
+perhaps--and I don't imagine I'll see him. He's harmless, but he's
+eccentric. Well, there was quite some excitement for a time.”
+
+“I should say there was. I thought it was a plan to rob me,” and the
+jeweler began putting away the diamond pins. In fact, the excitement
+so filled the minds of himself and Tom that neither of them thought any
+more of the object of the lad's visit, and the young inventor departed
+without purchasing the pin he had come after.
+
+It was not until he was out on the street, walking toward his home, that
+the matter came back to his mind.
+
+“I declare!” he exclaimed. “I didn't get that pin for Mary, after all!
+Well, never mind, I have a week until her birthday, and I can get it
+to-morrow.”
+
+He walked rapidly toward home, for the weather looked threatening, and
+Tom had no umbrella. He was musing on the happenings of the evening when
+he reached his house. His father was out, as was Garret Jackson, the
+engineer; and Mrs. Baggert, the housekeeper, was entertaining a lady in
+the sitting-room, so, as Tom was rather tired, he went directly to his
+own room, and, a little later got into bed.
+
+It was shortly after midnight when he was awakened by hearing a rattling
+on the window of his room. The reason he was able to fix the time
+so accurately was because as soon as he awakened he pressed a little
+electric button, and it illuminated the face of a small clock on his
+bureau. The hands pointed to five minutes past twelve.
+
+“Humph! That sounds like hail!” exclaimed Tom, as he arose, and looked
+out of the casement. “I wonder if any of the skylights of the airship
+shed are open? There might be some damage. Guess I'd better go out and
+take a look.”
+
+He had mentally reasoned this far before he had looked out, and when
+he saw that the moon was brightly shining in a clear sky, he was a bit
+surprised.
+
+“Why--that wasn't hail,” he murmured. “It isn't even raining. I wonder
+what it was?”
+
+He was answered a moment later, for a shower of fine gravel from the
+walk flew up and clattered against the glass. With a start, Tom looked
+down, and saw a dark figure standing under an apple tree.
+
+“Hello! Who's there?” called the lad, after he had raised the sash.
+
+“It's I--Mr. Jenks,” was the surprising answer.
+
+“Mr. Jenks?” repeated Tom.
+
+“Yes--Barcoe Jenks, of Earthquake Island.”
+
+“You here? What do you want?”
+
+“Can you come down?”
+
+“What for?”
+
+“Tom Swift, I've something very important to tell you,” was the answer
+in a low voice, yet which carried to Tom's ears perfectly. “Do you want
+to make a fortune for yourself--and for me?”
+
+“How?” Tom was beginning to think more and more that Mr. Jenks was
+crazy.
+
+“How? By helping me to discover the secret of Phantom Mountain, where
+the diamonds are made! Will you?”
+
+“Wait a minute--I'll come down,” answered Tom, and he began to grope for
+his clothes in the dim light of the little electric lamp.
+
+What was the secret of Phantom Mountain? What did Mr. Jenks really want?
+Could he make diamonds? Tom asked himself these questions as he hastily
+dressed to go down to his midnight visitor.
+
+
+
+
+CHAPTER III--A STRANGE STORY
+
+
+“Well, Mr. Jenks,” began Tom, when he had descended to the garden, and
+greeted the man who had acted so strangely on Earthquake Island, “this
+is rather an odd time for a visit.”
+
+“I realize that, Tom Swift,” was the answer, and the lad noticed that
+the man spoke much more calmly than he had that evening at the jewelry
+shop. “I realize that, but I have to be cautious in my movements.”
+
+“Why?”
+
+“Because there are enemies on my track. If they thought I was seeking
+aid to discover the secret of Phantom Mountain, my life might pay the
+forfeit.”
+
+“Are you in earnest, Mr. Jenks?”
+
+“I certainly am, and, while I must apologize for awakening you at this
+unseemly hour, and for the mysterious nature of my visit, if you will
+let me tell my story, you will see the need of secrecy.”
+
+“Oh, I don't mind being awakened,” answered Tom, good-naturedly, “but
+I will be frank with you, Mr. Jenks. I hardly can believe what you have
+stated to me several times--that you know how diamonds can be made.”
+
+“I can prove it to you,” was the quiet answer.
+
+“Yes, I know. For centuries men have tried to discover the secret of
+transmuting base metals into gold, and how to make diamonds by chemical
+means. But they have all been failures.”
+
+“All except this process--the process used at Phantom Mountain,”
+ insisted the queer man. “Do you want to hear my story?”
+
+“I have no objections.”
+
+“Then let me warn you,” went on Mr. Jenks, “that if you do hear it, you
+will be so fascinated by it that I am sure you will want to cast your
+lot in with mine, and aid me to get my rights, and solve the mystery.
+And I also want to warn you that if you do, there is a certain amount of
+danger connected with it.”
+
+“I'm used to danger,” answered Tom, quietly. “Let me hear your story.
+But first explain how you came to come here, and why you acted so
+strangely at the jewelry store.”
+
+“Willingly. I tried to attract your attention at the store, because I
+saw that you were going to buy a diamond, and I didn't want you to.”
+
+“Why not?”
+
+“Because I want to present you with a beautiful stone, that will answer
+your purpose as well or better, than any one you could buy. That will
+prove my story better than any amount of words or argument. But I could
+not attract your attention without also attracting that of the jeweler.
+He became suspicious, gave chase, and I thought it best to vanish. I
+hope no one was made to suffer for what may have been my imprudence.”
+
+“No, the lad whom Mr. Track caught was let go. But how did you happen to
+come to Shopton?”
+
+“To see you. I got your address from the owner of the yacht Resolute. I
+knew that if there was one person who could aid me to recover my rights,
+it would be you, Tom Swift. Will you help me? Will you come with me to
+discover the secret of Phantom Mountain? If we go, it will have to be in
+an airship, for in no other way, I think, can we come upon the place, as
+it is closely guarded. Will you come? I will pay you well.”
+
+“Perhaps I had better hear your story,” said the young inventor. “But
+first let me suggest that we move farther away from the house. My
+father, or Mr. Jackson, or the housekeeper, may hear us talking, and it
+may disturb them. Come with me to my private shop,” and Tom led the way
+to a small building where he did experimental work. He unlocked the door
+with a key he carried, turned on the lights, which were run by a storage
+battery, and motioned Mr. Jenks to a seat.
+
+“Now I'll hear your story,” said Tom.
+
+“I'll make it as short as possible,” went on the queer man. “To begin
+with, it is now several years ago since a poorly dressed stranger
+applied to me one night for money enough to get a meal and a bed to
+sleep in. I was living in New York City at the time, and this was
+midnight, as I was returning home from my club.
+
+“I was touched by the man's appearance, and gave him some money. He
+asked for my card, saying he would repay me some day. I gave it to him,
+little thinking I would hear from the man again. But I did. He called
+at my apartments about a week later, saying he had secured work as an
+expert setter of diamonds, and wanted to repay me. I did not want to
+take his money, but the fact that such a sorry looking specimen of
+manhood as he had been when I aided him, was an expert handler of gems
+interested me. I talked with the man, and he made a curious statement.
+
+“This man, who gave his name as Enos Folwell, said he knew a place where
+diamonds could be made, partly in a scientific manner, and partly by the
+forces of nature. I laughed at him, but he told me so many details that
+I began to believe him. He said he and some other friends of his, who
+were diamond cutters, had a plant in the midst of the Rocky Mountains,
+where they had succeeded in making several small, but very perfect
+diamonds. They had come to the end of their rope, though, so to speak,
+because they could not afford to buy the materials needed. Folwell
+said that he and his companions had temporarily separated, had left the
+mountain where they made diamonds, and agreed to meet there later when
+they had more money with which to purchase materials. They had all
+agreed to go out into civilization, and work for enough funds to enable
+them to go on with their diamond making.
+
+“I hardly knew whether to believe the man or not, but he offered proof.
+He had several small, but very perfect diamonds with him, and he gave
+them to me, to have tested in any way I desired.
+
+“I promised to look into the matter, and, as I was quite wealthy, as,
+in fact I am now, and if I found that the stones he gave me were real, I
+said I might invest some money in the plant.”
+
+“Were the diamonds good?” asked Tom, who was beginning to be interested.
+
+“They were--stones of the first water, though small. An expert gem
+merchant, to whom I took them, said he had never seen any diamonds like
+them, and he wanted to know where I got them. Of course I did not tell
+him.
+
+“To make a long story short, I saw Folwell again, told him to
+communicate with his companions, and to tell them that I would agree to
+supply the cash needed, if I could share in the diamond making. To this
+they agreed, and, after some weeks spent in preparation, a party of us
+set out for Phantom Mountain.”
+
+“Phantom Mountain?” interrupted Tom. “Where is it?”
+
+“I don't know, exactly--it's somewhere in the Rockies, but the exact
+location is a mystery. That is why I need your help. You will soon
+understand the reason. Well, as I said, myself, Folwell and the others,
+who were not exactly prepossessing sort of men, started west. When we
+got to a small town, called Indian Ridge, near Leadville, Colorado,
+the men insisted that I must now proceed in secret, and consent to be
+blindfolded, as they were not yet ready to reveal the secret of the
+place where they made the diamonds.
+
+“I did not want to agree to this, but they insisted, and I gave in,
+foolishly perhaps. At any rate I was blindfolded one night, placed in
+a wagon, and we drove off into the mountains. After traveling for some
+distance I was led, still blindfolded, up a steep trail.
+
+“When the bandage was taken off my eyes I saw that I was in a large
+cave. The men were with me, and they apologized for the necessity that
+caused them to blindfold me. They said they were ready to proceed with
+the making of diamonds, but I must promise not to seek to discover the
+secret until they gave me permission, nor was I to attempt to leave the
+cave. I had to agree.
+
+“Next they demanded that I give them a large sum, which I had promised
+when they showed me, conclusively, that they could make diamonds. I
+refused to do this until I had seen some of the precious stones, and
+they agreed that this was fair, but said I would have to wait a few
+days.
+
+“Well, I waited, and, all that while, I was virtually a prisoner in the
+cave. All I could learn was that it was in the midst of a great range,
+near the top, and that one of the peaks was called Phantom Mountain.
+Why, I did not learn until later.
+
+“At last one night, during a terrific thunder storm, the leader of the
+diamond makers--Folwell--announced that I could now see the stones made.
+The men had been preparing their chemicals for some days previous. I
+was taken into a small chamber of the cave, and there saw quite a
+complicated apparatus. Part of it was a great steel box, with a lever on
+it.
+
+“We will let you make some diamonds for yourself,” Folwell said to me,
+and he directed me to pull the lever of the box, at a certain signal.
+The signal came, just as a terrific crash of thunder shook the very
+mountain inside of which we were. The box of steel got red-hot, and when
+it cooled off it was opened, and was given a handful of white stones.
+
+“Were they diamonds?” asked Tom, eagerly.
+
+Mr. Jenks held out one hand. In the palm glittered a large
+stone--ostensibly a diamond. In the rays of the moon it showed all the
+colors of the rainbow--a beautiful gem. “That is one of the stones I
+made--or rather that I supposed I had made,” went on Mr. Jenks. “It is
+one of several I have, but they have not all been cut and polished as
+has this one.
+
+“Naturally I was much impressed by what I saw, and, after I had made
+certain tests which convinced me that the stones in the steel box were
+diamonds, I paid over the money as I had promised. That was my undoing.”
+
+“How?”
+
+“As soon as the men got the cash, they had no further use for me. The
+next I remember is eating a rude meal, while we discussed the future of
+making diamonds. I knew nothing more until I found myself back in the
+small hotel at Indian Ridge, whence I had gone some time previous, with
+the men, to the cave in the mountain.”
+
+“What happened?” asked Tom, much surprised by the unexpected outcome of
+the affair.
+
+“I had been tricked, that was all! As soon as the men had my
+money they had no further use for me. They did not want me to learn the
+secret of their diamond making, and they drugged me, carried me away
+from the cave, and left me in the hotel.”
+
+“Didn't you try to find the cave again?”
+
+“I did, but without avail. I spent some time in the Rockies, but no one
+could tell where Phantom Mountain was; in fact, few had heard of it, and
+I was nearly lost searching for it.
+
+“I came back East, determined to get even. I had given the men a
+very large sum of money, and, in exchange, they had given me several
+diamonds. Probably the stones are worth nearly as much as the money I
+invested, but I was cheated, for I was promised an equal share in the
+profits. These were denied me, and I was tricked. I determined to be
+revenged, or at least to discover the secret of making diamonds. It is
+my right.”
+
+“I agree with you,” spoke Tom.
+
+“But, up to the time I met you on Earthquake Island, I could form no
+plan for discovering Phantom Mountain, and learning the secret of the
+diamond makers,” went on Mr. Jenks. “I carried the gems about with me,
+as you doubtless saw when we were on the island. But I knew I needed an
+airship in which to fly over the mountains, and pick out the location of
+the cave where the diamonds are made.”
+
+“But how can you locate it, if you were blindfolded when you were taken
+there, Mr. Jenks?”
+
+“I forgot to tell you that, on our journey into the mountains, and just
+before I was carried into the cave, I managed to raise one corner of
+the bandage. I caught a glimpse of a very peculiarly shaped cliff--it
+is like a great head, standing out in bold relief against the moonlight,
+when I saw it. That head of rock is near the cave. It may be the
+landmark by which we can locate Phantom Mountain.”
+
+“Perhaps,” admitted the young inventor.
+
+“What I want to know is this,” went on Mr. Jenks. “Will you go with me
+on this quest--go in your airship to discover the secret of the diamond
+makers? If you will, I will share with you whatever diamonds we can
+discover, or make; besides paying all expenses. Will you go, Tom Swift?”
+
+The young inventor did not know what to answer. How far was Mr. Jenks
+to be trusted? Were the stones he had real diamonds? Was his story,
+fantastical as it sounded--true? Would it be safe for Tom to go?
+
+The lad asked himself these questions. Mr. Jenks saw his hesitation.
+
+“Here,” said the strange man, “I will prove what I say. Take this
+diamond. I intended it for you, anyhow, for what you did for me on
+Earthquake Island. Take it, and--and give it to the person for whom you
+were about to purchase a diamond to-night. But, first of all, take it to
+a gem expert, and get his opinion. That will prove the truth of what
+I say, Tom Swift, and I feel sure that you will cast your lot in with
+mine, and help me to discover the secret of Phantom Mountain, and aid me
+to get my rights from the diamond makers!”
+
+
+
+
+CHAPTER IV--ANDY FOGER GETS A FRIGHT
+
+
+Tom Swift considered a few minutes. On the face of it, the proposition
+appealed to him. He had been home some time now after his adventures on
+Earthquake Island, and he was beginning to long for more excitement. The
+search for the mysterious mountain, and the cave of the diamond makers,
+might offer a new field for him. But there came to him a certain
+distrust of Mr. Jenks.
+
+“I don't like to doubt your word,” began Tom, slowly, “but you know,
+Mr. Jenks, that some of the greatest chemists have tried in vain to make
+diamonds; or, at best, they have made only tiny ones. To think that any
+man, or set of men, made real diamonds as large as the ones you have,
+doesn't seem--well--” and Tom hesitated.
+
+“You mean you can hardly believe me?” asked Mr. Jenks.
+
+“I guess that's it,” assented Tom.
+
+“I don't blame you a bit!” exclaimed the odd man. “In fact, I didn't
+believe it when they told me they could make diamonds. But they proved
+it to me. I'm ready now to prove it to you.”
+
+“I'll tell you what I'll do. Here's this one stone, cut ready for
+setting. Here's another, uncut,” and Mr. Jenks drew from his pocket
+what looked like a piece of crystal. “Take them to any jeweler,” he
+resumed--“to the one in whose place I saw you to-night. I'll abide by
+the verdict you get, and I'll come here to-morrow night, and hear what
+you have to say.”
+
+“Why do you come at night?” asked Tom, thinking there was something
+suspicious in that.
+
+“Because my life might be in danger if I was seen talking to you, and
+showing you diamonds in the daytime--especially just now.
+
+“Why at this particular time?”
+
+“For the reason that the diamond makers are on my trail. As long as I
+remained quiet, after their shabby treatment of me, and did not try to
+discover their secret, they were all right. But, after I realized that
+I had been cheated out of my rights, and when I began to make an
+investigation, with a view to discovering their secret whereabouts, I
+received mysterious and anonymous warnings to stop.”
+
+“But I did not. I came East, and tried to get help to discover the cave
+of the diamond makers, but I was unsuccessful. I needed an airship, as
+I said, and no person who could operate one, would agree to go with
+me on the quest. Again I received a warning to drop all search for the
+diamond makers, but I persisted, and about a week ago I found I was
+being shadowed.”
+
+“Shadowed; by whom?” asked Tom.
+
+“By a man I never remember seeing, but who, I have no doubt, is one of
+the diamond-making gang.”
+
+“Do you think he means you harm?”
+
+“I'm sure of it. That is the reason I have to act so in secret, and come
+to see you at night. I don't want those scoundrels to find out what I am
+about to do. On my return from Earthquake Island, I again endeavored to
+interest an airship man in my plan, but he evidently thought me insane.
+Then I thought of you, as I had done before, but I was afraid you, too,
+would laugh at my proposition. However, I decided to come here, and I
+did. It seemed almost providential that my first view of you was in
+a jewelry shop, looking at diamonds. I took it as a good omen. Now it
+remains with you. May I call here to-morrow night, and get your answer?”
+
+Tom Swift made up his mind quickly. After all it would be easy enough to
+find out if the diamonds were real. If they were, he could then decide
+whether or not to go with Mr. Jenks on the mysterious quest. So he
+answered:
+
+“I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow
+night. In the meanwhile, for my own satisfaction, I'll let an expert
+look at these stones.”
+
+“Get the greatest diamond expert in the world, and he'll pronounce them
+perfect!” predicted the odd man. “Now I'll bid you goodnight, and be
+going. I'll be here at this time to-morrow.”
+
+As Mr. Jenks turned aside there was a movement among the trees in the
+orchard, and a shadowy figure was seen hurrying away.
+
+“Who's that?” asked the diamond man, in a hoarse whisper. “Did you see
+that, Tom Swift? Some one was here--listening to what I said! Perhaps it
+was the man who has been shadowing me!”
+
+“I think not. I guess it was Eradicate Sampson, a colored man who does
+work for us,” said Tom. “Is that you, Rad?” he called.
+
+“Yais, sah, Massa Tom, heah I is!” answered the voice of the negro,
+but it came from an entirely different direction than that in which the
+shadowy figure had been seen.
+
+“Where are you, Rad?” called the young inventor.
+
+“Right heah,” was the reply, and the colored man came from the direction
+of the stable. “I were jest out seein' if mah mule Boomerang were all
+right. Sometimes he's restless, an' don't sleep laik he oughter.”
+
+“Then that wasn't you over in the orchard?” asked Tom, in some
+uneasiness.
+
+“No, sah, I ain't been in de orchard. I were sleepin' in mah shack, till
+jest a few minutes ago, when I got up, an' went in t' see Boomerang.
+I had a dream dat some coon were tryin t' steal him, an' it sort ob
+'sturbed me, laik.”
+
+“If it wasn't your man, it was some one else,” said Mr. Jenks,
+decidedly.
+
+“We'll have a look!” exclaimed Tom. “Here, Rad, come over and scurry
+among those trees. We just saw some one sneaking around.”
+
+“I'll sure do dat!” cried the colored man. “Mebby it were somebody arter
+Boomerang! I'll find 'em.”
+
+“I don't believe it was any one after the mule,” murmured Mr. Jenks,
+“but it certainly was some one--more likely some one after me.”
+
+The three made a hasty search among the trees, but the intruder had
+vanished, leaving no trace. They went out into the road, which the moon
+threw into bold relief along its white stretch, but there was no figure
+scurrying away.
+
+“Whoever it was, is gone,” spoke Tom. “You can go back to bed, Rad,”
+ for the colored man, of late, had been sleeping in a shack on the Swift
+premises.
+
+“And I guess it's time for me to go, too,” added Mr. Jenks. “I'll be
+here to-morrow night, Tom, and I hope your answer will be favorable.”
+
+Tom did not sleep well the remainder of the night, for his fitful
+slumbers were disturbed by dreams of enormous caves, filled with
+diamonds, with dark, shadowy figures trying to put him into a red-hot
+steel box. Once he awakened with a start, and put his hand under his
+pillow to feel if the two stones Mr. Jenks had given him, were still
+there. They had not been disturbed.
+
+Tom made up his mind to find out if the stones were really diamonds,
+before saying anything to his father about the chance of going to seek
+Phantom Mountain. And the young inventor wished to get the opinion of
+some other jeweler than Mr. Track--at least, at first.
+
+“Though if this one proves to be a good gem, I'll have Mr. Track set it
+in a brooch, and give it to Mary for her birthday,” decided the young
+inventor. “Guess I'll take a run over to Chester in the Butterfly, and
+see what one of the jewelers there has to say.”
+
+In addition to his big airship, Red Cloud, Tom owned a small, swift
+monoplane, which he called Butterfly. This had been damaged by Andy
+Foger just before Tom left on the trip that ended at Earthquake Island,
+but the monoplane had been repaired, and Andy had left town, not having
+returned since.
+
+Telling his father that he was going off on a little business trip,
+which he often did in his aeroplane, Tom, with the aid of Mr. Jackson,
+the engineer, wheeled the Butterfly out of its shed.
+
+Adjusting the mechanism, and seeing that it was in good shape, Tom took
+his place in one of the two seats, for the monoplane would carry two.
+Mr. Jackson then spun the propellers, and, with a crackle and roar the
+motor started. Over the ground ran the dainty, little aeroplane, until,
+having momentum enough, Tom tilted the wing planes and the machine
+sailed up into the air.
+
+Rising about a thousand feet, and circling about several times to test
+the wind currents, Tom headed his craft toward Chester, a city about
+fifty miles from Shopton. In his pocket, snugly tucked away, were the
+two stones Mr. Jenks had given him.
+
+It was not long before Tom saw, looming up in the distance the church
+spires and towering factory chimneys of Chester, for his machine was a
+speedy one, and could make ninety miles an hour when driven. But now a
+slower speed satisfied our hero.
+
+“I'll just drop down outside of the city,” he reasoned, “for too much
+of a crowd gathers when I land in the street. Besides I might frighten
+horses, and then, too, it's hard to get a good start from the street.
+I'll leave it in some barn until I want to go back.”
+
+Tom sent his craft down, in order to pick out a safe place for a
+landing. He was then over the suburbs of the city, and was following the
+line of a straight country road.
+
+“Looks like a good place there,” he murmured. “I'll shut off the motor,
+and vol-plane down.”
+
+Suiting the action to the word, Tom shut off his power. The little craft
+dipped toward the ground, but the lad threw up the forward planes, and
+caught a current of air that sent him skimming along horizontally.
+
+As he got nearer to the ground, he saw the figure of a lad riding a
+bicycle along the country highway. Something about the figure struck Tom
+as being familiar, and he recognized the cyclist a moment later.
+
+“It's Andy Foger!” said Tom, in a whisper. “I wondered where he had been
+keeping himself since he damaged the Butterfly. Evidently he doesn't
+dare venture back to Shopton. Well, here's where I give him a scare.”
+
+Tom's monoplane was making no more noise, now, than a soaring bird. He
+was gliding swiftly toward the earth, and, with the plan in his mind of
+administering some sort of punishment to the bully, he aimed the machine
+directly at him.
+
+Nearer and nearer shot the monoplane, as quietly as a sheet of paper
+might fall. Andy pedaled on, never looking up nor behind him, A moment
+later, as Tom threw up his headplanes, to make his landing more easy,
+and just as he swooped down at one side of the cyclist, our hero let out
+a most alarming yell, right into Andy's ear.
+
+“Now I've got you!” he shouted. “I'll teach you to slash my aeroplane!
+Come with me!”
+
+Andy gave one look at the white bird-like apparatus that had flown up
+beside him so noiselessly, and, being too frightened to recognize Tom's
+voice, must have thought that he had been overtaken by some supernatural
+visitor.
+
+Andy gave a yell like an Indian, about to do a stage scalping act, and
+fairly dived over the handlebars of his bicycle, sprawling in a heap on
+the dusty road.
+
+“I guess that will hold you for a while,” observed Tom, grimly, as he
+put on the ground-brake and brought his monoplane to a stop not far from
+the fallen rider.
+
+
+
+
+CHAPTER V--A MYSTERIOUS MAN
+
+
+For several minutes Andy Foger did not arise. He remained prostrate in
+the dust, and Tom, observing him, thought perhaps the bully might have
+been seriously injured. But, a little later, Andy cautiously raised his
+head, and inquired in a frightened voice:
+
+“Is it--is it gone?”
+
+“Is what gone?” asked Tom, grimly.
+
+At the sound of his voice, Andy looked up. “Was that you, Tom Swift?” he
+demanded. “Did you knock me off my wheel?”
+
+“My monoplane and I together did,” was the reply; “or, rather, we
+didn't. It was the nervous reaction caused by your fright, and
+the knowledge that you had done wrong, that made you jump over the
+handlebars. That's the scientific explanation.”
+
+“You--you did it!” stammered Andy, getting to his feet. He wasn't hurt
+much, Tom thought.
+
+“Have it your own way,” resumed our hero. “Did you think it was a
+hob-goblin in a chariot of fire after you, Andy?”
+
+“Huh! Never mind what I thought! I'll have you arrested for this!”
+
+“Will you? Delighted, as the boys say. Hop in my airship and I'll take
+you right into town. And when I get you there I'll make a charge of
+malicious mischief against you, for breaking the propeller of the
+Butterfly and slashing her wings. I've mended her up, however, so she
+goes better than ever, and I can take you to the police station in jig
+time. Want to come, Andy?”
+
+This was too much for the bully. He knew that Tom would have a clear
+case against him, and he did not dare answer. Instead he shuffled over
+to where his wheel lay, picked it up, and rode slowly off.
+
+“Good riddance,” murmured Tom. He looked about, and saw that he was near
+a house, in the rear of which was a good-sized barn. “Guess I'll ask
+if I can leave the Butterfly there,” he murmured, and, ringing the
+doorbell, he was greeted by a man.
+
+“I'll pay you if you'll let me store my machine in the barn a little
+while, until I go into the city, and return,” spoke the lad.
+
+“Indeed, you're welcome to leave it there without pay,” was the answer.
+“I'm interested in airships, and, I'll consider it a favor if you'll let
+me look yours over while it's here.”
+
+Tom readily agreed, and a few minutes later he had caught a trolley
+going into the city. He was soon in one of the largest jewelry stores of
+Chester.
+
+“I'd like to get an expert opinion as to whether or not those stones are
+diamonds,” spoke Tom, to the polite clerk who came up to wait on him,
+and our hero handed over the two gems which Mr. Jenks had given him.
+“I'm willing to pay for the appraisement, of course,” the young inventor
+added, as he saw the clerk looking rather doubtfully at him, for Tom had
+on a rough suit, which he always donned when he flew in his monoplane.
+
+“I'll turn them over to our Mr. Porter, a gem expert,” said the clerk.
+“Please be seated.”
+
+The young man disappeared into a private office with the stones, and Tom
+waited. He wondered if he was going to have his trouble for his pains.
+Presently two elderly gentlemen came from the little room, on the glass
+door of which appeared the word “Diamonds.”
+
+“Who brought these stones in?” asked one of the men, evidently the
+proprietor, from the deference paid him by the clerk. The latter
+motioned to Tom.
+
+“Will you kindly step inside here?” requested the elderly man. When the
+door was closed, Tom found himself in a room which was mostly taken up
+with a bench for the display of precious stones, a few chairs, and some
+lights arranged peculiarly; while various scales and instruments stood
+on a table.
+
+“You wished an opinion on--on these?” queried the proprietor of the
+place. Tom noticed at once that the word “diamonds” was not used.
+
+“I wanted to find out if they were of any value,” he said. “Are they
+diamonds?”
+
+“Would you mind stating where you got them?” asked the other of the two
+men.
+
+“Is that necessary?” inquired the lad. “I came by them in a legitimate
+manner, if that's what you mean, and I can satisfy you on that point.
+I am willing to pay for any information you may give me as to their
+value.”
+
+“Oh, it isn't that,” the proprietor hastened to assure him. “But these
+are diamonds of such a peculiar kind, so perfect and without a flaw,
+that I wondered from what part of the world they came.”
+
+“Then they are diamonds?” asked Tom, eagerly.
+
+“The finest I have ever tested!” declared the other man, evidently Mr.
+Porter, the gem expert. “They are a joy to look at, Mr. Roberts,” he
+went on, turning to the proprietor. “If it is possible to get a supply
+of them you would be justified in asking half as much again as we charge
+for African or Indian diamonds. The Kimberly products are not to be
+compared to these,” and he looked at the two stones in his hand--the one
+cut, and sparkling brilliantly, the other in a rough state.
+
+“Do you care to state where these diamonds came from?” asked Mr.
+Roberts, looking critically at Tom.
+
+“I had rather not,” answered the lad. “It is enough for me to know that
+they are diamonds. How much is your charge?”
+
+“Nothing,” was the unexpected answer. “We are very glad to have had the
+opportunity of seeing such stones. Is there any chance of getting any
+more?”
+
+“Perhaps,” answered Tom, as he accepted the gems which the expert held
+out to him.
+
+“Then might we speak for a supply?” went on Mr. Roberts, eagerly. “We
+will pay you the full market price.”
+
+“What is the value of these stones?” asked Tom.
+
+Mr. Roberts looked at his gem expert.
+
+“It is difficult to say,” was the answer of the man who had handed Tom
+the gems. “They are so far superior to the usual run of diamonds, that
+I feel justified in saying that the cut one would bring fifteen hundred
+dollars, anywhere. In fact, I would offer that for it. The other is
+larger, though what it would lose in cutting would be hard to say. I
+should say it was worth two thousand dollars as it is now.”
+
+“Thirty-five hundred dollars for these two stones!” exclaimed Tom.
+
+“They are worth every cent of it,” declared Mr. Roberts. “Do you want to
+sell?”
+
+Tom shook his head. He could scarcely believe the good news. Mr. Jenks
+had told the truth. Now the young inventor could go with him to seek the
+diamond makers.
+
+“Can you get any more of these?” went on Mr. Roberts.
+
+“I think so--that is I don't know--I am going to try,” answered the lad.
+
+“Then if you succeed I wish you would sell us some,” fairly begged the
+proprietor of the store.
+
+“I will,” promised Tom, but he little knew what lay before him, or
+perhaps he would not have made that promise. He thanked the diamond
+merchant for his kindness, and arranged to have the cut stone set in a
+pin for Miss Nestor. The uncut gem Tom took away with him.
+
+Thinking of many things, and wondering how best to start in his airship
+Red Cloud for the mysterious Phantom Mountain, Tom hurried back to where
+he had left the monoplane, wheeled it out, and was soon soaring through
+the air toward Shopton.
+
+“I think I'll go with Mr. Jenks,” he decided, as he prepared for a
+landing in the open space near his aeroplane shed. “It will be a
+risky trip, perhaps, but I've taken risks before. When Mr. Jenks comes
+to-night I'll tell him I'll help him to get his rights, and discover the
+secret of the diamond makers.”
+
+As Tom was wheeling the Butterfly into the shed, Eradicate came out to
+help him.
+
+“Dere's a gen'man here to see yo', Massa Tom,” said the colored man.
+
+“Who is it?”
+
+“I dunno. He keep askin' ef yo' de lad what done bust up Earthquake
+Island, an' send lightnin' flashes up to de sky, an' all sech questions
+laik dat.”
+
+“It isn't Mr. Damon; is it, Rad? He hasn't been around in some time.”
+
+“No, Massa Tom, it ain't him. I knows dat blessin' man good an' proper.
+I jest wish he'd bless mah mule Boomerang some day, an' take some oh
+de temper out ob him. No, sah, it ain't Massa Damon. De gen'man's in de
+airship shed waitin' fo' you.”
+
+“In the airship shed! No strangers are allowed in there, Rad.”
+
+“I knows it, Massa Tom, but he done persisted his se'f inter it, an'
+he wouldn't come out when I told him; an' your pa an' Mr. Jackson ain't
+home.”
+
+“I'll see about this,” exclaimed Tom, striding to the large shed, where
+the Red Cloud was kept. As he entered it he saw a man looking over the
+wonderful craft.
+
+“Did you want to see me?” asked Tom, sharply, for he did not like
+strangers prowling around.
+
+“I did, and I apologize for entering here, but I am interested in
+airships, and I thought you might want to hire a pilot. I am in need
+of employment, and I have had considerable to do with balloons and
+aeroplanes, but never with an airship like this, which combines the two
+features. Do you wish to hire any one.”
+
+“No, I don't!” replied Tom, sharply, for he did not like the looks of
+the man.
+
+“I was told that you did,” was the rather surprising answer.
+
+“Who told you?”
+
+The man looked all around the shed, before replying, as if fearful of
+being overheard. Then, stepping close to Tom, he whispered:
+
+“Mr. Jenks told me!”
+
+“Mr. Jenks?” Tom could not conceal his astonishment.
+
+“Yes. Mr. Barcoe Jenks. But I did not come here to merely ask you for
+employment. I would like to hire out to you, but the real object of my
+visit was to say this to you.”
+
+The man approached still closer to Tom, and, in a lower voice, and one
+that could scarcely be heard, he fairly hissed:
+
+“Don't go with Barcoe Jenks to seek the diamond makers!”
+
+Then, before Tom could put out a hand to detain him, had the lad so
+wished, the man turned suddenly, and fairly ran from the shed.
+
+
+
+
+CHAPTER VI--MR. DAMON IS ON HAND
+
+
+The young inventor stood almost spellbound for a few moments. Then
+recovering himself he made a dash for the door through which the
+mysterious man had disappeared. Tom saw him sprinting down the road, and
+was half-minded to take after him, but a cooler thought warned him that
+he had better not.
+
+“He may be one of those men who are on Mr. Jenks' trail,” reasoned Tom,
+in which case it might not be altogether safe to attempt to stop him,
+and make him explain. Or he may be a lunatic, and in that case it
+wouldn't be altogether healthy to interfere with him.
+
+“I'll just let him go, and tell Mr. Jenks about him when he comes
+to-night. But I must warn Rad never to let him in here again. He might
+damage the airship.”
+
+Calling to the colored man, Tom pointed to the stranger, who was almost
+out of sight down the road, and said earnestly:
+
+“Rad, do you see that fellow?”
+
+“I sho do, Massa Tom, but I sorter has t' strain my eyes t' do it. He's
+goin' laik my mule Boomerang does when he's comm' home t' dinnah.”
+
+“That's right, Rad. Well, never let that man set foot inside our fence
+again! If he comes, and I'm home, call me. If I'm away, call dad or Mr.
+Jackson, and if you're here alone, drive him away, somehow.”
+
+“I will, Massa Tom!” exclaimed the colored man, earnestly, “an' if I
+can't do it alone, I'll get Boomerang t' help. Once let dat ar' mule
+git his heels on a pusson, an' dat pusson ain't goin' t' come bodderin'
+around any mo'--that is, not right away.”
+
+“I believe you, Rad. Well, keep a lookout for him, and don't let him
+in,” and with that Tom entered the house to think over matters. They
+were beginning to assume an aspect he did not altogether like. Not that
+Tom was afraid of danger, but he preferred to meet it in the open, and
+the warning, or threat, of the mysterious man disquieted him.
+
+When Mr. Swift came home, a little later, his son told him of the
+midnight interview with Mr. Jenks, for, up to this time, the aged
+inventor was unaware of it, and Tom also gave an account of the
+diamonds, speaking of their value.
+
+“And do you propose to go to Phantom Mountain, in search of the makers
+of these gems, Tom?” asked Mr. Swift.
+
+“I had about decided to do so, dad.”
+
+“And you're going in the Red Cloud?'
+
+“Yes.”
+
+“Who are going with you?”
+
+“Well, Mr. Jenks will go, of course, and I've no doubt but that if I
+mention the prospective trip to Mr. Damon, that he'll bless his skating
+cap, or something like that, and come along.”
+
+“I suppose so, Tom, and I'd like to have you take him. But I think
+you'll need some one else.”
+
+“Because, from what you have told me, you are going out to a dangerous
+part of the country, and you may have to deal with unscrupulous men.
+Three of you are hardly enough to cope with them. You ought to have at
+least another member of your party. If I was not busy on my invention of
+a new wireless motor I would go along, but I can't leave. You might take
+Mr. Jackson.”
+
+“No, you need him here to help you, dad.”
+
+“How about Eradicate?”
+
+Tom smiled.
+
+“Rad would get homesick for his mule Boomerang, and I'd have to bring
+him back just when we'd found the diamonds,” replied the young inventor.
+“No, we'll have to think of some one else. I'll ask Mr. Damon, and then
+I'll consider matters further. I expect to see Mr. Jenks to-night, and
+he may have some one in mind.”
+
+“Perhaps that will be a good plan. Well, Tom, I trust you will take good
+care of yourself, and not run into unnecessary danger. Is the Red Cloud
+in good shape for the voyage?”
+
+“It needs looking over. I'm going to get right at it.”
+
+“It's a pretty indefinite sort of a quest you're going on, Tom, my son.
+How do you expect to find Phantom Mountain?”
+
+“Well, it's going to be quite a task. In the first place we'll head for
+Leadville, Colorado, and then we'll go to Indian Ridge and make some
+inquiries. We may get on the track of the place that way. If we don't,
+why I'll take the airship up as high as is necessary and sort of
+prospect until we see that big cliff that's shaped like a head. That
+will give us something to go by.”
+
+“Well, do the best you can. If you can discover the secret of making
+diamonds it will be a valuable one.”
+
+“I guess it will, dad; and Mr. Jenks is entitled to know it, for he paid
+his good money to that end. He has promised to go halves with me, as
+payment for the use of the airship, and I must say the two diamonds he
+gave me last night have proved very valuable.”
+
+“Two diamonds, Tom? You only showed me one, an uncut gem;” and Mr. Swift
+looked at his son.
+
+“Oh, the other--er--the other is--I left it with a jeweler,” and Tom
+blushed a trifle, as he thought of the present he contemplated making to
+Mary Nestor.
+
+That afternoon, as Tom was out in the shed of the Red Cloud looking over
+the airship, to see what would be necessary to do to it in order to get
+it in shape for a long trip, he heard voices outside.
+
+“Yes--yes, I know the way in perfectly well,” he caught. “You needn't
+bother to come, my good fellow. Just step this way, and I'll show you
+something worth seeing.”
+
+“I wonder if it's that mysterious man coming back?” thought Tom. He
+dropped the tool he was using, and hurried to the door. As he approached
+it he heard the voice continue.
+
+“Why bless my shoe laces, Mr. Parker! You'll see a wonderful airship, I
+promise you. Wonderful! Bless my hatband, but I hope Tom is here!”
+
+“Mr. Damon!” exclaimed our hero, as he recognized the tones of his
+eccentric friend. “But who is with him?”
+
+A moment later he caught sight of the gentleman who was always blessing
+himself, or something. Behind him stood another man, whose features Tom
+could not see plainly.
+
+“Hello, Tom Swift!” called Mr. Damon. “Looking over the Red Cloud, eh?
+Does that mean you're off on another trip?”
+
+“I guess it does,” answered the lad.
+
+“Where to this time? if I may ask.”
+
+“I'm thinking of going off to the mountains to find a band of men
+engaged in making diamonds,” replied Tom.
+
+“Making diamonds! Bless my finger ring! Making diamonds! A trip to the
+mountains! Bless my disposition! but do you know I'd like to go with
+you!”
+
+“I was thinking of asking you, Mr. Damon.”
+
+“Were you? Bless my heart, I'm glad you thought of me. You don't by any
+possible chance want another person; do you?”
+
+“We were thinking of having four in the party, Mr. Damon,” and Tom
+wondered who was with his eccentric friend.
+
+“Then bless my election ticket! This is the very chance for you, Mr.
+Parker!” cried Mr. Damon. “Will you go with us? It will be just what you
+need,” and Mr. Damon stepped aside, revealing to Tom the features of Mr.
+Ralph Parker, the scientist who had correctly predicted the destruction
+of Earthquake Island.
+
+
+
+
+CHAPTER VII--MR. PARKER PREDICTS
+
+
+Tom Swift was a most generous lad, but when he saw that Mr. Damon had
+with him Mr. Parker, the gloomy scientist, who seemed to take delight in
+predicting disasters, our hero's spirits were not exactly of the best.
+He would have much preferred not to take Mr. Parker on the quest for the
+diamond makers, but, since Mr. Damon had mentioned it, he did not see
+how he could very well refuse.
+
+“But perhaps he won't care to go,” thought Tom.
+
+He was undeceived a moment later, however, for the scientist remarked:
+
+I am very glad to meet you once more, Mr. Swift. I have scarcely thanked
+you enough for what you did for us in erecting your wireless station on
+Earthquake Island, which, as you recall, I predicted would sink into
+the sea. It did, I am glad to say, not because I like to see islands
+destroyed, but because science has been vindicated. Now I have just
+heard you remark that you are about to set off to the mountains in
+search of some men who are making diamonds. I need hardly state that
+this is utterly useless, for no diamonds, commercially valuable, can be
+made by men. But the trip may be valuable in that it will permit me to
+demonstrate some scientific facts.
+
+“Therefore, if you will permit me, I will be very glad to accompany you
+and Mr. Damon. I shall be delighted, in short, and I can start as soon
+as you are ready.”
+
+“There's no hope for it!” thought Tom, dismally. “I suppose he'll wake
+up every morning, and predict that before night the world will come to
+an end, or he'll prophesy that the airship will blow up, and vanish,
+when about seven miles above the clouds. Well, there's no way out of it,
+so here goes.”
+
+Thereupon Tom welcomed the scientist as cordially as he could, and
+invited him to form one of the party that would set off in the airship
+to search for Phantom Mountain.
+
+“Bless my jewelry box!” exclaimed Mr. Damon, when this formality was
+over. “Tell me more about it, Tom.”
+
+Which our hero did, stating the need of maintaining secrecy on account
+of the danger to Mr. Jenks. Mr. Damon and Mr. Parker both agreed to say
+nothing about the matter, and then the scientist became much interested
+in the Red Cloud, which he closely examined. He even complimented Tom on
+the skill shown in making it, and, contrary to our hero's expectation,
+did not predict that it would blow up the next time it was used.
+
+“How did you happen to arrive just at this time, Mr. Damon?” asked Tom.
+
+“It was partly due to Mr. Parker,” was the answer. “I had not seen him
+since we were rescued from the island, until a few days ago he called
+on me at my home. I happened to mention that you lived near here, and
+suggested that he might like to see some of your inventions. He agreed,
+and we came over in my auto. And now, bless my liver-pin! I find you
+about to start off on another trip.”
+
+“And have you fully decided to go with me?” asked Tom. “There may be
+danger, and I don't like the way that mysterious man behaved.”
+
+“Oh, bless my revolver!” cried Mr. Damon. “I'm used to danger by this
+time. Of course I'm going, and so is Mr. Parker. Do you know,” and the
+man, who was always blessing something, came closer to the lad, and
+whispered: “Do you know, Tom, Mr. Parker is a very peculiar individual.”
+
+“I'm sure of it,” answered the young inventor, looking at the gentleman
+in question, who was then inside the airship cabin.
+
+“But he's all right, even if he is predicting unpleasant things,” went
+on Mr. Damon. “I think we'll get better acquainted with him after a
+bit.”
+
+“I hope so,” agreed Tom, but he did not realize then how close his
+companionship with Mr. Parker was to be, nor what dangers they were to
+share later.
+
+The friends talked at considerable length of the prospective trip, and
+Tom, by this time, had ascertained what needed to be done to the airship
+to get it in shape to travel. It would take about a week, and, in the
+meanwhile, Mr. Damon would go home and get his affairs in order for
+the voyage. Tom's father was introduced to Mr. Parker, and, the former,
+finding that the scientist held some views in common with him, invited
+the gloomy predictor to remain at the Swift home until the Red Cloud was
+ready to sail. Tom could not repress a groan at this, but he decided he
+would have to make the best of it.
+
+Mr. Damon left for home that afternoon, promising to be on hand at the
+time set to start for Phantom Mountain.
+
+Tom was up waiting for Mr. Jenks at twelve o'clock that night. Shortly
+after the hour he saw a dark figure steal into the orchard. At first he
+feared lest it might be one of the spies who were, he was now convinced,
+on the trail of the man who was seeking to discover the secret of the
+diamond makers. But a whistle, which came to the lad's ear a moment
+later (that being a signal Mr. Jenks had agreed to sound), told Tom that
+it was none other than the visitor he expected.
+
+“All right, Mr. Jenks, I'm here,” called Tom, cautiously. “Come over
+this way,” and he went out from the shadow of the house, where he had
+been waiting, and met the men. “We'll go into my private work-shop,” the
+youth added, leading the way.
+
+“Have you decided to go with me?” asked Mr. Jenks, in an anxious
+whisper. “Did you find the diamonds to be real ones?”
+
+“I did; and I'm going,” spoke Tom.
+
+“Good! That relieves my mind. But we are still in danger. I was followed
+by my shadower to-day, and only succeeded in shaking him off just before
+coming here. I don't believe he knows what I am about to do.”
+
+“Oh, yes he does,” said Tom.
+
+“He does? How?”
+
+“Because he was here, and warned me against you!”
+
+“You don't mean it! Well, they are getting desperate! We must be on our
+guard. What sort of a man was he?”
+
+Tom described the fellow, and Mr. Jenks stated that this tallied with
+the appearance of the person who had been shadowing him.
+
+“But we'll fool them yet!” cried Tom, who had now fully entered into the
+spirit of the affair. “If they can follow us in the Red Cloud they're
+welcome to. I think we'll get ahead of them.”
+
+He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed that
+it would add to the strength of the party to take these two gentlemen
+along.
+
+“Though I can't say I care so much for Mr. Parker,” he added. “But now
+as to ways and means. When can we start?”
+
+Thereupon he and Tom talked over details in the seclusion of the little
+office, and arranged to leave Shopton in about a week. In the meanwhile
+the airship would be overhauled, stocked with supplies and provisions,
+and be made ready for a swift dash to the mountains.
+
+“And now I must be going,” said Mr. Jenks. “I have a great deal to do
+before I can start on this trip, and I hope I am not prevented by any of
+those men who seem to be trailing me.”
+
+“How could they prevent you?” Tom wanted to know.
+
+“Oh, there are any number of ways,” was the answer. “But I'm glad you
+found that my diamonds were real. We'll soon have plenty, if all goes
+well.”
+
+As Mr. Jenks left the shop, he started back, in some alarm.
+
+“What's the matter?” asked Tom.
+
+“Over there--I thought I saw a figure sneaking along under the
+trees--that man--perhaps--”
+
+“That's Eradicate, our colored helper,” replied Tom, with a laugh.
+“I posted him there to see that no strangers came into the orchard.
+Everything all right, Rad?” he asked, raising his voice.
+
+“Yais, sah, Massa Tom. Nobody been around yeah this night.”
+
+“That's good. You can go to bed now,” and Eradicate, yawning loudly,
+went to his shack. A little later Tom sought his own room, Mr. Jenks
+having hurried off to town, where he was boarding.
+
+The next few days saw Tom busily engaged on the airship, making some
+changes and a few repairs that were needed. His father, Eradicate and
+Mr. Jackson helped him. As for Mr. Parker, the scientist, he went about
+the place, being much interested in the various machines which Tom or
+Mr. Swift had patented.
+
+At other times the scientist would stroll about the extensive grounds,
+making what he said were “observations.” One afternoon Tom saw him,
+apparently much excited, kneeling down back of a shed, with his ear to
+the ground.
+
+“What is the matter?” asked the lad, thinking perhaps Mr. Parker might
+be ill.
+
+“Have you ever had any earthquakes here, Tom Swift?” asked the
+scientist, quietly.
+
+“Earthquakes? No. We had enough of them on the island.”
+
+“And you are going to have one here, in about two minutes!” cried Mr.
+Parker. “I predict that this place will be shaken by a tremendous shock
+very soon. We had all better get away from the vicinity of buildings.”
+
+“What makes you think there will be an earthquake?” asked Tom.
+
+“Because I can hear the rumbling beneath the ground at this very minute.
+It is increasing in volume, showing that the tremors are working this
+way. There will soon be a great subterranean upheaval! Listen for
+yourself.”
+
+Tom cast himself down on the grass. Placing his ear close to the ground
+he did hear a series of dull thuds. He arose, not a little alarmed.
+There had never been any earthquakes in Shopton, yet he had great
+respect for Mr. Parker's scientific attainments.
+
+Just then Eradicate Sampson came along. He saw Tom and Mr. Parker lying
+flat on the ground, and surprise showed on his honest, black face.
+
+“Fo' de land sakes!” cried Eradicate. “What am de mattah now, Massa
+Tom?”
+
+“Earthquake coming,” answered Tom, briefly. “Better get away from the
+buildings, Rad. They might fall!” Tom's face showed the alarm he felt.
+What would happen to all of his valuable machines--to the Red Cloud?
+
+“Earthquake?” murmured Eradicate, and he, too, cast himself down to
+listen. A moment later he arose with a laugh.
+
+“What's the matter?” cried Tom.
+
+“Why, dat ain't no earthquake!” declared the colored man.
+
+“No. Then perhaps you know what it is,” said Mr. Parker, somewhat
+sharply.
+
+“Course I knows what it am,” answered Eradicate, with dignity. “Dat
+noise am my mule Boomerang, kickin' in his stable, on account oh me not
+feedin' him yet. Dat's what it am. I'se gwine right now t' gib him his
+oats, and den yo' see dat de noise stop. Boomerang allers kick dat way
+when he's hungry. I show yo'!”
+
+And, sure enough, when Eradicate had gone to the mule's stable,
+which was near where Mr. Parker had heard the mysterious sounds, they
+immediately ceased.
+
+“Dat mule was all de earthquake dere was around here,” said the colored
+man as he came out.
+
+Mr. Parker walked away, saying nothing, and Tom did not make any
+comments--just then.
+
+
+
+
+CHAPTER VIII--OFF FOR THE WEST
+
+
+It was a great relief to Tom, to find that there was no danger from an
+earth tremor. Now that he had made up his mind to go in search of
+the diamond makers, he wanted nothing to interfere with it. Lest the
+feelings of Mr. Parker might be hurt by the mistake he had made, the
+young inventor cautioned Eradicate not to say anything more about the
+matter.
+
+“'Deed an' I won't,” the colored man promised. “I'se only too glad dere
+wa'n't no earthquake, dat's what I is.”
+
+As for Mr. Parker, he did not appear much put out by his error in
+predicting.
+
+“I am sure that what I heard was a tremor, due to some distant
+earthquake shock,” he said. “The mule's kicking was only a coincidence.”
+
+And Tom let him have his way about it. The week was drawing to a close,
+and the Red Cloud was nearly in shape for the voyage. At almost the
+last minute Tom found that he needed some electrical apparatus for the
+airship, and as he had to go to Chester for it, he decided he would make
+the trip in his monoplane, and, while in the city, would also get the
+diamond pin he was having made for Mary Nestor.
+
+He started off early one morning, in the swift little craft Butterfly,
+and soon had reached Chester. The diamond brooch was ready for him.
+
+“It is one of the most beautiful stones we have ever set,” the diamond
+merchant told him. “Don't forget, if you find any more, Mr. Swift, to
+let us have a chance to bid on them.”
+
+“I may,” Tom promised, rather indefinitely. Then, having purchased his
+electrical supplies, he made a quick trip to Shopton, stopping on the
+way to call on Miss Nestor.
+
+“Why Tom, I'm delighted to see you!” cried the girl, blushing prettily.
+“Did you come for some apple turnovers?” and she laughed, as she
+referred to a call Tom had once paid, when a new cook had been engaged,
+and when the pastry formed a feature of the meal.
+
+“No turnovers this time,” said the young inventor. “I came to wish you
+many happy returns of the day.”
+
+“Oh, you remembered my birthday! How nice of you!”
+
+“And here is something else,” added our hero, rather awkwardly, as he
+handed her the diamond pin.
+
+“Oh, Tom! This for me! Oh, it's too lovely--it's far too much!”
+
+“It isn't half enough!” he declared, warmly.
+
+“Oh, what a large diamond!” Mary cried as she saw the sparkling stone.
+“I never saw one so large and beautiful!”
+
+“It's just as easy to make them large as small,” explained Tom.
+
+“Make them?” she looked the surprise she felt.
+
+“Yes, I'm about to start for the place where diamonds are made.”
+
+“Oh, Tom! But isn't it dangerous? I mean won't you have to go to some
+far country--like Africa--to get to where diamonds are made?”
+
+“Well, we are going on quite a trip, but not as far as that. And as
+for the danger--well, we'll have to take what comes,” and he told her
+something of the proposed quest.
+
+“Oh, it sounds--sounds scary!” Mary exclaimed, when she had heard of Mr.
+Jenks' experience. “Do be careful, Tom!”
+
+“I will,” he promised, and, somehow he was glad that she had cautioned
+him thus--and in such tones as she had used. For Mary Nestor was a girl
+that any young chap would have been glad to have manifest an interest in
+him.
+
+“Well, I guess I'll have to say good-by,” spoke Tom, at length. “We
+expect to start in a couple of days, and I may not get another chance to
+see you.”
+
+“Oh, I--I hope you come back safely,” faltered Mary, and then she held
+out her hand, and Tom--well, it's none of our affair what Tom did
+after that, except to say that he hurried out, fairly jumped into his
+monoplane, and completed the trip home.
+
+As the Red Cloud has been fully described in the volume entitled “Tom
+Swift and His Airship,” we will not go into details about it now.
+Sufficient to say that it was a combination of a biplane and dirigible
+balloon. It could be used either as one or the other, and the gas-bag
+feature was of value when the wind was too great to allow the use of the
+planes, or when the motive power, for some reason stopped. In that event
+the airship could remain suspended far above the clouds if necessary.
+There was provision for manufacturing the gas on board.
+
+The Red Cloud was fitted up to accommodate about ten persons, though it
+was seldom that this number was carried. Two persons could successfully
+operate the machinery. There were sleeping berths, and in the main cabin
+a sitting-room, a dining-room, and a kitchen. There was also the motor
+compartment, and a steering tower, from which the engines could be
+controlled.
+
+It was in this craft that the seekers after the diamond makers proposed
+undertaking the trip. Mr. Damon came on from his home in Waterfield
+about two days before the date set to leave, and Mr. Jenks, had, three
+days before this, taken up his abode at the Swift home. Mr. Parker, as
+has been stated, was already there, and he had put in his time making
+a number of scientific observations, though he had made no more
+predictions.
+
+Nothing more had been seen of the mysterious man who had warned Tom,
+and the young inventor and Mr. Jenks began to hope that they had thrown
+their enemies off the track.
+
+“Though I don't imagine they'll give up altogether,” said Mr. Jenks.
+“They're too desperate for that. We'll have trouble with them yet.”
+
+“Well, it can't be helped,” decided Tom. “We'll try and be ready for it,
+when it comes,” and then, dismissing the matter from his mind, he busied
+himself about the airship.
+
+The food and supplies had all been put aboard, and they expected to
+start the next morning. In order to make sure that any stones which they
+might succeed in getting from the diamond makers were real gems, a set
+of testing apparatus was taken along. Mr. Parker had had some experience
+in this line, and, in spite of the fact that he might make direful
+predictions, Tom was rather glad, after all, that the scientist was
+going to accompany them.
+
+“But what is worrying me,” said Mr. Damon, “is what we are going to do
+after we get to Phantom Mountain. What are your plans, Mr. Jenks? Will
+you go in, and demand your share of the diamond-making business?”
+
+“I have a right to it, as I invested a large sum in it, and I am
+entitled to more than a half-share. But, of course, I can't say what
+I'll do until I get there. We may have to act very secretly.”
+
+“I'm inclined to think we will,” said Tom. “My plan would be to gain
+access to the cave, if possible, and watch them at work. We might be
+able to discover the secret of making diamonds, and, after all, that's
+what you want, isn't it, Mr. Jenks?”
+
+“Yes, I paid my money for the secret, and I ought to have it. If I can
+get it quietly, so much the better. If not, I'll fight for my rights!”
+ and he looked very determined.
+
+“Bless my powder horn!” cried Mr. Damon. “That's the way to talk! And
+so we're to go cruising about in the air, looking for a mountain shaped
+like a man's head.”
+
+“That's it,” agreed Mr. Jenks, “and when we find it we will be near
+Phantom Mountain, and the diamond makers.”
+
+The final details were completed that night. The last of the supplies
+had been put aboard, the larder was well stocked, the diamond testing
+apparatus was stored safely away, and all that remained was for the
+adventurers to board the Red Cloud in the morning, and soar away.
+
+That night Tom was uneasy. Several times he got up, and looked toward
+the shed where the airship was stored. He could not rid himself of
+the idea that the men to whose interest it was that the diamond-making
+secret remain undiscovered, might attempt to wreck the airship before
+the start. Consequently both Eradicate Sampson and Engineer Jackson were
+on guard. Tom looked from his window, to the shed where the Red Cloud
+was housed. He saw nothing to cause him any uneasiness.
+
+“I guess I'm just nervous,” he mused. “But, all the same, I'll be glad
+when we've started.”
+
+They were all up early the next morning, Mr. Damon beginning the day by
+blessing the sunrise, and many other things that struck his fancy.
+The airship was wheeled out of the shed, and Tom gave her a final
+inspection.
+
+“It's all right,” he declared. “All aboard!”
+
+“Now, do be careful,” begged Mr. Swift. “Don't take too many chances,
+Tom.”
+
+“I'll not.”
+
+The adventurers were in the forward part of the ship, and Tom had taken
+his place at the wheels and levers in the pilot house. As he was about
+to start the motor he looked toward the road, and saw a horse and
+carriage. In the vehicle was a girlish figure, at the sight of which Tom
+blushed and smiled. He waved his hand.
+
+“I came to wish you good luck!” cried Mary Nestor, for it was she in the
+carriage.
+
+“Thanks!” cried Tom, leaning from the window of the pilot house. “It was
+good of you to get up so early.”
+
+“Oh. I'm always up early,” she informed him.
+
+“Look out that the motor doesn't scare your horse,” Tom warned her.
+
+“Old Dobbin doesn't mind anything,” was her answer. “I'll see that he
+doesn't run away with me, as long as you're not on earth to rescue me.
+Good-by, Tom!”
+
+“Good-by!” he called, and then he pulled the lever that set in motion
+the motor, and whirled the great propellers about. They whizzed around
+with a roar, and the Red Cloud, shivering and trembling with the
+vibration, rose in the air like some great bird.
+
+“We're off for the West and Phantom Mountain!” called Tom to his
+companions.
+
+As the airship soared upward, Eradicate Sampson ran forward from where
+he had been standing near his mule Boomerang. He waved his hands, and
+shouted something.
+
+“Bless my hatband! What does he want?” asked Mr. Damon, watching him
+curiously.
+
+“It sounds as if he were calling to us to come back,” spoke Mr. Parker.
+
+“It's too late now,” decided Tom. “Maybe he forgot to tell us good-by,”
+ but, he felt a vague wonder at Eradicate's odd motions; for the colored
+man was pointing toward the stern of the airship, as if there was
+something wrong there. But the Red Cloud soared on.
+
+
+
+
+CHAPTER IX--A WARNING BY WIRELESS
+
+
+Rapidly the airship ascended, and, when it was high over the town of
+Shopton, Tom headed the craft due west. Looking down he tried to descry
+Mary Nestor, in her carriage, but the trees were in the way, their
+interlocking branches hiding the girl. Tom did see crowds of other
+persons, though, thronging the streets of Shopton, for, though the young
+inventor had made many flights, there was always a novelty about them,
+that brought out the curious.
+
+“A good start, Tom Swift,” complimented Mr. Parker. “Is it always as
+easy as this?”
+
+“Starting always is,” was the answer, “though, as the Irishman said,
+coming down isn't sometimes quite so comfortable.”
+
+“Bless my gizzard! That's so,” cried the eccentric Mr. Damon. “Can we
+vol-plane to earth in the Red Cloud, Tom?”
+
+“Yes, but not as easily as in the Butterfly. However I hope we will not
+have to. Now, Mr. Damon, if you will just take charge of the steering
+apparatus for a minute, I want to go aft.”
+
+“What for?”
+
+“I wish to see if everything is all right. I can't imagine why Eradicate
+was making those queer motions.”
+
+Mr. Damon, who knew how to operate the Red Cloud, was soon guiding her
+on the course, while Tom made his way to the rear compartments, through
+the motor room, where the stores of supplies and food were kept. He made
+a careful examination, looking from an after window, and even going out
+on a small, open platform, but could discover nothing wrong.
+
+“I guess Rad was just capering about without any special object,” mused
+Tom, but it was not long after this that they learned to their dismay,
+that the colored man had had a method in his madness.
+
+On his way back through the motor room Tom looked to the machinery,
+and adjusted some of the auxiliary oil feeders. The various pieces of
+apparatus were working well, though the engine had not yet been speeded
+up to its limit. Tom wanted it to “warm-up” first.
+
+“Everything all right?” asked Mr. Damon, as Tom rejoined them in the
+pilot house, which was just forward of the living room in the main
+cabin.
+
+“Yes, I can't imagine what made Rad act that way. But I'll set the
+automatic steering gear now, Mr. Damon, and then you will be relieved.”
+
+Mr. Jenks was gazing off toward the west--to where he hoped to discover
+the secret of Phantom Mountain.
+
+“How do you like it?” asked Tom.
+
+“It's great,” replied the diamond man. “I've never been in an airship
+before, and it's different than what I expected; but it's great! It's
+the only craft that will serve our purpose among the towering mountain
+peaks, where the diamond makers are hidden. I hope we can find them.”
+
+In a little while the Red Cloud was skimming along at faster speed,
+guided by the automatic rudders, so that no one was needed in the pilot
+house, since there was no danger of collisions. Airships are not quite
+numerous enough for that, yet, though they may soon become so.
+
+Tom and the others devoted several hours to arranging their staterooms
+and bunks, and getting their clothing stowed away, and when this was
+done Mr. Parker and Mr. Jenks sat gazing off into space.
+
+“It's hard to realize that we are really in an airship,” observed the
+diamond man. “At first I thought I would be frightened, but I'm not a
+bit. It doesn't seem as if anything could happen.”
+
+“Something is likely to happen soon,” said Mr. Parker, suddenly, as he
+gazed at some weather instruments on the cabin wall.
+
+“Bless my soul! Don't say that!” cried Mr. Damon. “What is it?”
+
+“I think, from my observations, that we will soon have a hurricane,”
+ said the scientific man. “There is every indication of it;” and he
+seemed quite delighted at the prospect of his prediction coming true.
+
+“A hurricane!” cried Mr. Damon. “I hope it isn't like the one that blew
+us to Earthquake Island.”
+
+“Oh, I think there will be no danger,” spoke Tom. “If it comes on to
+blow we will ascend or descend out of the path of the storm. This craft
+is not like the ill-fated Whizzer. I can more easily handle the Red
+Cloud; even in a bad storm.”
+
+“I'm glad to hear that,” remarked Mr. Jenks. “It would be too bad to be
+wrecked before we got to Phantom Mountain.”
+
+“Well, I predict that we will have a bad storm,” insisted Mr. Parker,
+and Tom could not help wishing that the scientist would keep his gloomy
+forebodings to himself.
+
+However the storm had not developed up to noon, when Tom, with Mr.
+Damon's help, served a fine meal in the dining-room. In the afternoon
+the speed of the ship was increased, and by night they had covered
+several hundred miles. Through the darkness the Red Cloud kept on,
+making good time. Tom got up, occasionally, to look to the machinery,
+but it was all automatically controlled, and an alarm bell would sound
+in his stateroom when anything went wrong.
+
+“Bless my napkin!” exclaimed Mr. Damon the next morning, as they sat
+down to a breakfast of fruit, ham and eggs and fragrant coffee, “this is
+living as well as in a hotel, and yet we are--how far are we above the
+earth, Tom?” he asked, turning to the young inventor.
+
+“About two miles now. I just sent her up, as I thought I detected that
+storm Mr. Parker spoke of.”
+
+“I told you it would come,” declared the scientist, and there was a
+small hurricane below them that morning, but only the lower edge of it
+caught the Red Cloud, and when Tom sent her up still higher she found a
+comparatively quiet zone, where she slid along at good speed.
+
+That afternoon Tom busied himself about some wires and a number of
+complicated pieces of apparatus which were in one corner of the main
+cabin.
+
+“What are you doing now?” asked Mr. Jenks, who had been talking with Mr.
+Parker, and showing that scientist some of the manufactured diamonds.
+
+“Getting our wireless apparatus in shape,” answered the lad. “I should
+have done it before, but I had so much to do that I couldn't get at it.
+I'm going to send off some messages. Dad will want to know how we are
+doing.”
+
+As he worked away, he also made up his mind to send another message, in
+care of his father, for there was a receiving station in the Swift home.
+And to whom this message was addressed Tom did not say, but we fancy
+some of our readers can guess.
+
+Finally, after several hours of work, the wireless was in shape to send
+and receive messages. Tom pulled over the lever, and a crackling sound
+was heard, as the electricity leaped from the transmitters into space.
+Then he clamped the receiver on his ear.
+
+“All ready,” he announced. “Has anybody any messages they wish sent?”
+ For, with the courtesy of a true host he was ready to serve his guests
+before he forwarded his own wireless notes.
+
+“Just tell my wife that I'm enjoying myself,” requested Mr. Damon.
+“Bless my footstool! But this is great! We're off the earth yet,
+connected with it.”
+
+Mr. Jenks had no one to whom he wanted to send any word, but Mr. Parker
+wish to wire to a fellow scientist the result of some observations made
+in the upper air.
+
+Tom noted all the messages down, and then, when all was in readiness he
+began to call his home station. He knew that either his father or Mr.
+Jackson, the engineer, could receive the wireless.
+
+But, no sooner had the young inventor sent off the first few dots and
+dashes representing “S. I.”--his home station call--than he started and
+a look of surprise came over his face.
+
+“They're calling us!” he exclaimed.
+
+“Who is?” asked Mr. Jenks.
+
+“My house--my father. He--he's been trying to get us ever since we
+started, but I didn't have the wireless in shape to receive messages.
+Oh, I hope it's not too late!”
+
+“Too late! Bless my soul, too late for what?” gasped Mr. Damon, somewhat
+alarmed by Tom's manner.
+
+The lad did not answer at once. He was intently listening to a series
+of dots and dashes that clicked in the telephone receiver clamped to his
+left ear. On his face there was a look of worriment.
+
+“Father has just sent me a message,” he said. “It's a warning flashed
+through space! He's been trying to get it to me since yesterday!”
+
+“What is it?” asked Mr. Jenks, rising from his seat.
+
+“The mysterious man is aboard the airship--hidden away!” cried Tom.
+“That's what Eradicate was trying to call to our attention as we started
+off. Eradicate saw his face at a rear window, and tried to warn us! The
+mysterious man is a stowaway on board!”
+
+
+
+
+CHAPTER X--DROPPING THE STOWAWAY
+
+
+Tom's excited announcement startled Mr. Damon and the others as much as
+if the young inventor had informed them that the airship had exploded
+and was about to dash with them to the earth. The men leaped to their
+feet, and stared at the lad.
+
+“A stowaway on board!” cried Mr. Damon. “Bless my soul! How did he--”
+
+“Are you sure that message is straight?” asked Mr. Jenks. “Did Eradicate
+see the man?”
+
+“He says he did,” answered Tom. “The man is hidden away on board
+now--probably among the stores and supplies.”
+
+“Bless my tomato sauce!” exploded Mr. Damon. “I hope he doesn't eat them
+all up!”
+
+“We must get him out at once!” declared Mr. Jenks.
+
+“I knew something would happen on this voyage,” came from Mr. Parker. “I
+predicted it from the first!”
+
+Tom thought considerable, but he did not answer the scientist just
+then. Another communication was coming to him by wireless. He listened
+intently.
+
+“Father says,” the lad told his companions “that Eradicate only had
+a glimpse of the man at the last moment. He was looking from the rear
+storeroom window--he's the same man who called on me that time--Rad
+remembers him very well.”
+
+“Bless my shoes! What's to be done?” inquired Mr. Damon, looking around
+helplessly.
+
+“We must get him out, that's all,” decided Mr. Jenks; with vigor. “Get
+him out and drop him overboard!”
+
+“Drop him overboard!” cried Mr. Parker, in horror.
+
+“Not exactly, but get rid of him,” proceeded the diamond seeker. “That
+man is one of my enemies. He has been sent by the band of diamond makers
+hidden among the mountains, to spy on me, and, if possible, prevent me
+from seeking to discover their secret. He tried to work on Tom's Swift's
+fears, and frighten him from using his airship on this quest. Then, when
+he failed, the man must have sneaked into the shed, and hidden himself
+in the ship. We must get rid of him, or he may wreck the Red Cloud!”
+
+“That's so!” cried Tom. “We must try to capture him. I think we had
+better--” the lad paused, and again listened to the wireless message.
+“Father says Eradicate saw the man have a gun, so we must be careful,”
+ the young inventor translated the dots and dashes.
+
+“Bless my powder horn!” exploded Mr. Damon.
+
+“We shall have to proceed cautiously then,” spoke Mr. Jenks. “If he is
+like any others in the gang he is a desperate man.”
+
+“Better sneak up on him then, if we can,” proposed Mr. Parker. “There
+are enough of us to cope with one man, even if he is armed. You have
+weapons aboard, haven't you?” he inquired of Tom.
+
+“Yes,” was the hesitating answer, “but I don't want to use them if I
+can help it. Not only because of the danger, and a dislike of shedding
+blood, but because a stray bullet might pierce the gas bag and damage
+the ship.”
+
+“That's so,” agreed Mr. Jenks. “Well, I guess if we go at it the right
+way we can capture him without any shooting. But we must talk more
+quietly--we ought to have whispered--he may have heard us.”
+
+“I don't think so,” replied Tom. “The storeroom is far enough off so
+that he couldn't hear us. Besides, the motor makes such a racket that
+he couldn't distinguish what we were talking about, even if he heard our
+voices. So, unless he heard the wireless working, and suspects something
+from that, he probably doesn't know that we are aware of his presence
+aboard.”
+
+“But why do you think he has remained quiet all this while, Tom?” asked
+Mr. Damon.
+
+“Probably he wants to wait until the ship is farther out west,”
+ suggested Mr. Jenks. “Then he will be nearer his friends, and can get
+help, if he needs it.”
+
+“And do you really believe he would destroy the Red Cloud?” asked Mr.
+Parker.
+
+“I think that all he is waiting for is a favorable chance,” declared
+the diamond seeker. “He would destroy the craft, and us too, if he could
+prevent us from discovering the secret of Phantom Mountain, I believe.”
+
+“Then we must get ahead of him,” decided Tom, quietly. “I have just
+flashed to dad a message, telling him that we will heed his warning. Now
+to capture the stowaway!”
+
+“And while we're about it, give him a good scare when we do get him,”
+ suggested Mr. Jenks.
+
+“How?” asked Tom.
+
+“Threaten to drop him overboard. Perhaps that will make him tell how
+he happened to get in our ship, and what are the plans of the gang of
+diamond makers. We may get valuable information that way.”
+
+“I don't believe you can scare such fellows much,” was Tom's opinion,
+but it was agreed to try.
+
+“How are you going to capture him?” asked Mr. Parker. “If he has a gun
+it won't be any too easy to go in the storeroom, and drag him out.”
+
+“We'll have to use a little strategy,” decided Tom, and then they
+discussed several plans. The one finally adopted was that Tom and Mr.
+Damon should enter the storeroom, casually, as if in search of food to
+cook for supper. They would discuss various dishes, and Mr. Damon was to
+express a preference for something in the food line, the box containing
+which, was well back in the room. This would give the two a chance
+to penetrate to the far end of the apartment, without arousing the
+suspicions of the hidden man, who, doubtless, would be listening to the
+conversation.
+
+“And as soon as we get sight of him, you and I will jump right at him,
+Mr. Damon,” said Tom. “Jump before he has a chance to use his gun. Mr.
+Jenks and Mr. Parker will be waiting outside the room, to catch him if
+he gets away from us. I'll have some ropes ready, and we'll tie him up,
+and--well, we'll decide later what to do with him.”
+
+“All right. I'm ready as soon as you are, Tom,” said the eccentric man.
+“Come ahead.”
+
+They went softly to the storeroom, and listened at the door. There was
+no sound heard save that made by the machinery.
+
+“I wonder if he's really here?” whispered Mr. Damon.
+
+“We'll soon find out,” answered Tom. “Let's go in.”
+
+They entered, and, in pursuance of their plan, Tom and his friend talked
+of various foods.
+
+“I think I'd like some of that canned lobster, with French dressing on,”
+ spoke the eccentric man.
+
+“That's away in the back end of the room,” said Tom, in a loud voice.
+“It's under a lot of boxes.”
+
+“Then I'll help you get it out! Bless my frying pan! but I am very fond
+of lobster!” exclaimed Mr. Damon, in as natural tones as was possible
+under the circumstances.
+
+He and Tom moved cautiously back among the boxes and barrels. They were
+glancing about with eager eyes. Tom switched on an electric light, and,
+the instant he did so, he was aware of a movement in a little space
+formed by one box which was placed on top, of two others. The lad saw a
+dark figure moving, as if to get farther out of sight.
+
+“I've got him!” cried Tom, making a dive for the shadow.
+
+A moment later the young inventor was bowled over, as a dark figure
+leaped over his head.
+
+“Catch him, Mr. Damon!” he cried.
+
+“Bless my hatband! I--I--” Mr. Damon's voice ended in a grunt. He, too,
+had been knocked down by the fleeing man.
+
+“Look out, Mr. Jenks!” cried Tom, to warn those on guard at the door of
+the storeroom.
+
+There was the report of a gun, some excited shouts, and when Tom could
+scramble to his feet, and rush out, he beheld Mr. Parker calmly sitting
+on a struggling man, while Mr. Jenks held a gun, that was still smoking.
+
+“We caught him!” cried the scientist.
+
+“Anybody hurt?” asked Tom, anxiously.
+
+“No, I knocked up his gun as he fired,” explained Mr. Jenks. “Where are
+the ropes, Tom?”
+
+The cords were produced and the man, who had now ceased to struggle,
+was tightly bound. He uttered not a word, but he smiled grimly when Mr.
+Damon remarked:
+
+“I guess I'll go back in the storeroom, Tom, and see how much food he
+ate.”
+
+“Oh, I guess he didn't take much,” declared the lad. “He wasn't there
+long enough.”
+
+“Well, Farley Munson, so it's you, is it?” asked Mr. Jenks, as he
+surveyed the prisoner.
+
+“Do you know him?” asked Tom, in some surprise.
+
+“He was in with the diamond makers,” said Mr. Jenks. “He was one of
+those who took me to the secret cave. But it will be the last time he
+ever goes there. How high up are we, Tom?”
+
+“About two miles. Why?”
+
+“I guess that will be far enough to let him fall,” went on the diamond
+seeker. “Come on, Mr. Damon, help me throw him overboard!”
+
+“You--you're not going to throw me over--with the airship two miles
+high; are you?” gasped the man.
+
+“Will you tell us what we want to know, if we don't?” asked Mr. Jenks.
+
+“What do you want to know?”
+
+“How you got aboard, and what your object was in coming.”
+
+“That's easy enough. I had been hanging around the shed for several
+days, watching a chance to get in. Finally I saw it, when that colored
+man went to feed his mule, and I slipped in, and hid in the airship. The
+stores were all in then, and I stowed myself away among the boxes. I had
+food and water, so I didn't touch any of yours,” and he looked at Mr.
+Damon, who seemed much relieved.
+
+“And what was your object?” demanded Mr. Jenks.
+
+“I wanted to prevent you from going to Phantom Mountain.”
+
+“How?”
+
+“By destroying the airship if need be. But I hoped to accomplish it by
+other means. I would have stopped at nothing, though, to prevent you.
+You must keep away from there!”
+
+“And if we refuse?” asked Tom.
+
+“Then you'll have to take what comes!”
+
+“But not from you!” exclaimed Mr. Jenks. “We're going to get rid of
+you.”
+
+The man's face showed the alarm he felt.
+
+“Oh, don't worry,” said Mr. Jenks, quickly, “we're not going to toss you
+overboard. We're not as desperate as your crowd. But we're going to
+get rid of you, and then go on before you can send any word to your
+confederates. We'll put you off in the most lonesome spot we can find,
+and I guess you'll be some time getting back to civilization. By that
+time we'll have the secret of the diamonds.”
+
+“You never will!” declared the man, firmly. And he would say nothing
+more, though by threats and promises Mr. Jenks tried to get from him
+something about the men in with him, and where the cave of the diamonds
+was located.
+
+Heavily bound with ropes the man was locked in a small closet, to be
+kept there until a favorable spot was reached for letting him go. Mr.
+Jenks' plan, of dropping him down in some place where he would have
+difficulty in sending on word to his confederates was considered a good
+one.
+
+Three days later, in crossing over a lonely region, near the Nebraska
+National Forest, Farley Munson, which was one of the names the spy went
+by, was dropped off the airship, when it was sent down to within a few
+feet of the earth.
+
+“It will take you some time to get to a telegraph office,” said Mr.
+Jenks, as a package of food, and a flask of water was tossed down to the
+stowaway. He shook his fist at those in the airship, and shouted after
+them:
+
+“You'll never discover the secret of Phantom Mountain!”
+
+“Yes, we will,” declared Tom, as he sent the Red Cloud high into the air
+again.
+
+
+
+CHAPTER XI--A WEARY SEARCH
+
+
+During the three days when the stowaway had been kept a prisoner, the
+Red Cloud had made good time on her western trip. She was now about two
+hundred and fifty miles from Leadville, Colorado, and Tom knew he could
+accomplish that distance in a short time. It was necessary, therefore,
+since they were so close to the place where the real search would begin,
+to make some more definite plans.
+
+“We will need to replenish our supply of gasoline,” said Tom, shortly
+after the stowaway had been dropped, and when the young inventor had
+made a general inspection of the airship.
+
+“Is it all gone?” inquired Mr. Damon.
+
+“Not all, but we will soon be in the wildest part of the Rocky
+Mountains, and gasoline is difficult to procure there. So I want to fill
+all our reserve tanks. But I would rather do that before we get far into
+Colorado.”
+
+“Why?” inquired Mr. Parker.
+
+“Because airships are not so common but what the appearance of one
+attracts attention. Ours is sure to be talked about, and commented on.
+In that case, in spite of our precaution in putting Munson off in this
+lonely place, word of the Red Cloud being in the vicinity of Leadville
+may reach the diamond makers, and put them on their guard. We want to
+take them unawares if we can.”
+
+“That's so,” agreed Mr. Jenks. “We had better get our gasoline at the
+first stopping place, then, and proceed with our search. Our first
+object ought to be to look for the landmark--the head of stone. Then we
+can begin to prospect about a bit.”
+
+“My idea, exactly,” declared Tom. “Well, then, I'll go down at the
+first place we cross, where we can get gasoline, and then we'll be in a
+position to hover in the air for a long time, without descending.”
+
+The airship kept on her way, traveling slowly the remainder of that day,
+and at dusk, when there was less chance of big crowds seeing them, the
+Red Cloud was sent down on the outskirts of a large village. Tom and Mr.
+Damon went to a supply store, and arranged to have a sufficient quantity
+of the gasoline taken out to the airship. It was delivered after dark,
+and little talk was occasioned by the few who were aware of the presence
+of the craft. Then, once more, they went aloft, and Tom sent several
+wireless messages to Shopton, including one to Miss Nestor.
+
+“Please tell my wife that I am well, and that I have a good appetite,”
+ said Mr. Damon.
+
+Mr. Parker also sent a message to a scientific friend of his, stating
+that he made some observations among the mountains, of the region in
+which the airship then was, and that the indications were that a great
+landslide would soon take place.
+
+“That won't worry us,” spoke Tom, “for we'll be far above it.”
+
+“I hope we will be near enough to enable me to observe it, and make
+some scientific notes,” came from Mr. Parker. “I am positive that one
+of these mountain peaks that we saw to-day will disappear in a landslide
+within a few days. I have an instrument somewhat like the one that
+records earthquakes, and it has been acting strangely of late.”
+
+Tom wondered what enjoyment Mr. Parker got out of life, when he was
+always looking for some calamity to happen, but the scientist seemed
+to take as much pleasure in his gloomy forebodings now, as he had on
+Earthquake Island.
+
+They reached the vicinity of Leadville the next day, but took care to
+keep high above the city, so that the airship could not be observed.
+With powerful glasses they examined the mountainous country, looking for
+the little settlement of Indian Ridge.
+
+“There it is!” exclaimed Mr. Jenks, just as dusk was settling down. “I
+can make out the hotel I stopped at. Now we can really begin our search.
+The next thing is to find the stone head, and then, I think, I will have
+my bearings.”
+
+“We'll begin the hunt for that landmark in the morning,” said Tom.
+
+High in the air hovered the Red Cloud. At that distance above the earth
+she must have looked like some great bird, and the adventurers thought
+it unlikely that any one in the vicinity of Leadville would observe
+them.
+
+The quest for the great mountain peak, that looked like a stone head,
+was under way. Back and forth sailed the airship. Sometimes she was
+enveloped in fog, and no sight could be had of the earth below. At
+other times there were rain storms, which likewise prevented a view. Mr.
+Parker was on the lookout for his predicted mountain landslide, but it
+did not occur, and he was much disappointed.
+
+“It's queer I can't pick out that landmark,” said Mr. Jenks after two
+days of weary searching, when their eyes were strained from long peering
+through telescopes. “I'm sure it was around Indian Ridge, yet we've
+covered almost all the ground in this neighborhood, and I haven't had a
+glimpse of it.”
+
+“Perhaps it was destroyed in a landslide, or some cataclysm of nature,”
+ suggested Mr. Parker. “That is very possible.”
+
+“If that's the case we're going to have a hard time to locate the cave
+of the diamond makers,” answered Mr. Jenks, “but I hope it isn't so.”
+
+They continued the search for another day, and then Tom, as they sat
+in the comfortable cabin of the airship that night, hovering almost
+motionless (for the motor had been shut down) made a proposition.
+
+“Why not descend in some secluded place,” he suggested, “and wander
+around on foot, making inquiries of the miners. They may know where the
+stone head is, or they may even know about Phantom Mountain.”
+
+“Good idea,” spoke Mr. Jenks. “We'll do it.”
+
+Accordingly, the next morning, the Red Cloud was lowered in a good but
+lonely landing place, and securely moored. It was in a valley, well
+screened from observation, and the craft was not likely to be seen,
+but, to guard against any damage being done to it by passing hunters or
+miners, Mr. Parker and Mr. Damon agreed to remain on guard in it, while
+Tom and Mr. Jenks spent a day or two traveling around, making inquiries.
+
+The young inventor and his companion proceeded on foot to a small
+settlement, where they hired horses on which to make their way about.
+They were to be gone two days, and in that time they hoped to get on the
+right trail.
+
+
+
+
+CHAPTER XII--THE GREAT STONE HEAD
+
+
+It was a wild and desolate country in which Tom Swift and Mr. Jenks
+were traveling. Villages were far apart, and they were at best but
+small settlements. In their journeys from place to place they met few
+travelers.
+
+But of these few they made cautious inquiries as to the location
+of Phantom Mountain, or the landmark known as the great stone head.
+Prospectors, miners and hunters, whom they asked, shook their heads.
+
+“I've heard of Phantom Mountain,” said one grizzled miner, “but I
+couldn't say where it is. Maybe it's only a fish story--the place may
+not even exist.”
+
+“Oh, it does, for I've been there!” exclaimed Mr. Jenks.
+
+“Then why don't you go back to it?” asked the miner.
+
+“Because I can't locate it again,” was the reply.
+
+“Humph! Mighty queer if you've seen a place once, and can't get to it
+again,” and the man looked as if he thought there was something strange
+about Tom and his companion. Mr. Jenks did not want to say that he had
+been taken to the mountain blindfolded, for that would have caused too
+much talk.
+
+“I think if we spent to-night in a place where the miners congregate,
+listened to their talk, and put a few casual questions to them, more as
+if we were only asking out of idle curiosity, we might learn something,”
+ suggested Tom.
+
+“Very well, we'll try that scheme.”
+
+Accordingly, after they had left the suspicious miner the two proceeded
+to a small milling town, not far from Indian Ridge. There they engaged
+rooms for the night at the only hotel, and, after supper they sat around
+the combined dance hall and gambling place.
+
+There were wild, rough scenes, which were distasteful to Tom, and to Mr.
+Jenks, but they felt that this was their only chance to get on the right
+trail, and so they stayed. As strangers in a western mining settlement
+they were made roughly welcome, and in response to their inquiries about
+the country, they were told many tales, some of which were evidently
+gotten up for the benefit of the “tenderfeet.”
+
+“Is there a place around here called Phantom Mountain?” asked Tom, at
+length, as quietly as he could.
+
+“Never heard of it, stranger,” replied a miner who had done most of the
+talking. “I never heard of it, and what Bill Slatterly don't know ain't
+worth knowin'. I'm Bill Slatterly,” he added, lest there be some doubt
+on that score.
+
+“Isn't there some sort of a landmark around here shaped like a great
+stone head?” went on Tom, after some unimportant questions. “Seems to me
+I've heard of that.”
+
+“Nary a one,” answered Mr. Slatterly. “No stone heads, and no Phantom
+Mountains--nary a one.
+
+“Who says there ain't no Phantom Mountains?” demanded an elderly miner,
+who had been dozing in one corner of the room, but who was awakened by
+Slatterly's loud voice. “Who says so?”
+
+“I do,” answered the one who claimed to know everything.
+
+“Then you're wrong!” Tom's heart commenced beating faster than usual.
+
+“Do you mean to say you've seen Phantom Mountain, Jed Nugg?” demanded
+Slatterly.
+
+“No, I ain't exactly seen it, an' I don't want to, but there is such
+a place, about sixty mile from here. Folks says it's haunted, and them
+sort of places I steer clear from.”
+
+“Can you tell me about it?” asked Mr. Jenks, eagerly. “I am interested
+in such things.”
+
+“I can't tell you much about it,” was the reply, “and I wouldn't git too
+interested, if I was you. It might not be healthy. All I know is that
+one time my partner and I were in hard luck. We got grub-staked, and
+went out prospectin'. We strayed into a wild part of the country about
+sixty mile from here, and one night we camped on a mountain--a wild,
+desolate place it was too.”
+
+The miner stopped, and began leisurely filling his pipe.
+
+“Well?” asked Tom, trying not to let his voice sound too eager.
+
+“Well, that was Phantom Mountain.”
+
+The miner seemed to have finished his story.
+
+“Is that all?” asked Mr. Jenks. “How did you know it was Phantom
+Mountain?”
+
+“'Cause we seen the ghost--my partner and I--that's why!” exclaimed the
+man, puffing on his pipe. “As I said, we was campin' there, and 'long
+about midnight we seen somethin' tall and white, and all shimmerin',
+with a sort of yellow fire, slidin' down the side of the mountain. It
+made straight for our camp.”
+
+“Huh! Guess you run, didn't you, Jed?” asked Bill Slatterly.
+
+“Course we did. You'd a run too, if you seen a ghost comm' at you, an'
+firin' a gun.”
+
+“Ghosts can't fire guns!” declared Bill. “I guess you dreamed it, Jed.”
+
+“Ghosts can't fire guns, eh? That's all you know about it. This one did,
+and to prove I didn't dream it, there was a bullet hole in my hat next
+mornin'. I could prove it, too, only I ain't got that hat any more. But
+that was Phantom Mountain, strangers, an' my advice to you is to keep
+away from it. I was on it but I didn't exactly see it, 'cause it was
+dark at the time.”
+
+“Was it near a peak that looked like a stone head?” asked Tom.
+
+“It were, stranger, but I didn't take much notice of it. Me and my
+partner got out of them diggin's next day, and I never went back. I
+ain't never said much about this place, but it's called Phantom Mountain
+all right, and I ain't the only one that's seen a ghost there. Other
+grub-stakers has had the same experience.”
+
+“Why ain't I never heard about it?” demanded Bill, suspiciously.
+
+“'Cause as why you're allers so busy talkin' that you don't never listen
+to nothin' I reckon,” was Jed's answer, amid laughter.
+
+“Can you tell us what trail to take to get there?” asked Tom, of the
+miner.
+
+“Yes, it's called the old silver trail, and you strike it by goin' to a
+place called Black Gulch, about forty mile from here. Then it's twenty
+mile farther on. But take my advice and don't go.”
+
+“Can it be reached by way of Indian Ridge?” asked Mr. Jenks, wondering
+how he had been taken to the cave of the diamond makers. He did not
+remember Black Gulch.
+
+“Yes, you can git there by Indian Ridge way, but it's more dangerous.
+You're likely to lose your way, for that's a trail that's seldom
+traveled.” Mr. Jenks thought that, perhaps, was the reason the gang had
+taken him that way. “It's easier to get to the stone head and Phantom
+Mountain by Black Gulch, but it ain't healthy to go there, strangers,
+take my advice on that,” concluded the miner, as he prepared to go to
+sleep again.
+
+Tom could scarcely contain the exultation he felt. At last, it seemed,
+they were on the trail. He motioned to Mr. Jenks, and they slipped
+quietly from the place, just as another dance was beginning.
+
+“Now for Black Gulch!” cried Tom. “We must hurry back to the airship,
+and tell the good news.
+
+“It's too late to-night,” decided Mr. Jenks, and so they waited until
+morning, when they made an early start.
+
+They found Mr. Damon and Mr. Parker anxiously awaiting their return. Mr.
+Damon blessed so many things that he was nearly out of breath, and Mr.
+Parker related something of the observations he had made.
+
+“I think I have discovered traces of a dormant volcano,” he said. “I am
+in hopes that it will have an eruption while we are here.”
+
+“I'm not,” spoke Tom, decidedly. “We'll start for Black Gulch as soon as
+possible.”
+
+The airship once more rose in the air, and, following the directions
+the miner had given him, Tom pointed his craft for the depression in the
+mountains which had been given the name Black Gulch. It was reached in
+a short time, and then, making a turn up a long valley the airship
+proceeded at reduced speed.
+
+“We ought to see that stone head soon now,” spoke Tom, as he peered from
+the windows of the pilot house.
+
+“It's queer we didn't notice it when we were up in the air,” remarked
+Mr. Jenks. “We've been over this place before, I'm sure of it.”
+
+The next moment Mr. Damon uttered a cry. “Bless my watch-chain!” he
+exclaimed. “Look at that!”
+
+He pointed off to the left. There, jutting out from the side of a steep
+mountain peak was a mass of stone--black stone--which, as the airship
+slowly approached, took the form and shape of a giant's head.
+
+“That's it! That's it!” cried Tom. “The great stone head!”
+
+“And now for Phantom Mountain and the diamonds!” shouted Mr. Jenks, as
+Tom let the airship slowly settle to the bottom of the valley.
+
+
+
+
+CHAPTER XIII--ON PHANTOM MOUNTAIN
+
+
+Out from the Red Cloud piled Tom and the others. They made a rush for
+the irregular mass of rock which bore so strong a resemblance to the
+head of some gigantic man.
+
+“That's the one! That's the thing I saw when they were taking me along
+here blindfolded!” exclaimed Mr. Jenks. “I'm sure we're on the right
+trail, now!”
+
+“But what gets me, though,” remarked Mr. Damon, “is why we couldn't see
+that landmark when we were up in the air. We had a fine view, and ought
+to have been able to pick it out with the telescopes.”
+
+The adventurers saw the reason a few seconds later. The image was
+visible only from one place, and that was directly looking up the
+valley. If one went too far to the right or left the head disappeared
+from view behind jutting crags, and it was impossible to see it from
+overhead, because the head was almost under a great spur of a mighty
+mountain.
+
+“We might have hunted for it a week in the airship, and been directly
+over it,” said Tom, “and yet we would never have seen it.”
+
+“Yes, but we never would have gotten here in such good shape if it
+hadn't been for your wonderful craft,” declared Mr. Jenks. “It brought
+us here safely and quickly, and enabled us to elude the men who tried to
+keep us back. We're here in spite of them. If we had traveled by train
+they might have interfered with us in a dozen ways.”
+
+“That's so,” agreed Mr. Damon. “Well, now we're here, what's to be
+done? Which way do we start to reach the cave where the diamonds are
+manufactured, Mr. Jenks?”
+
+“That I can't say. As you know, I only had a momentary glimpse of this
+stone head as they were taking me along the trail. Then one of the men
+noticed that the bandage had slipped and he pulled it into place. So I
+really can't say which direction to take now, in order to discover the
+secret.”
+
+“How long after you saw the head before you reached the cave?” asked
+Tom. “In that way we may be able to tell how far away it is.”
+
+“Well, I should say it was about two or three hours after I saw the
+head, before we got to the halting place, and I was carried into the
+cave. That would make it several miles from here, for we went in a
+wagon.”
+
+“Yes, and they might have driven in a round-about way, in order to
+deceive you,” suggested Mr. Damon. “At best we have but a faint idea
+where the diamond cave is, but we must search for it; eh, Tom?”
+
+“Certainly. We'll start right in. And as the airship will be of but
+little service to us now, I suggest that we leave it in this valley.
+It is very much secluded, and no one will harm it, I think. We can then
+start off prospecting, for I have a large portable tent, and we can
+carry enough food with us, with what game we can shoot, to enable us to
+live. I have a regular camping outfit on board.”
+
+“Fine!” cried Mr. Parker, “and that will give me a chance to make some
+observations among the mountains, and perhaps I can predict when a
+landslide, or an eruption of some dormant volcano, may occur.”
+
+“Bless my stars!” cried Mr. Damon. “I don't wish you any bad luck, Mr.
+Parker, but I sincerely hope nothing of the sort happens! We had enough
+of that on Earthquake Island!”
+
+“One can not halt the forces of nature,” said the scientist, solemnly.
+“There are many towering peaks around here which may contain old
+volcanoes. And I notice the presence of iron ore all about. This must be
+a wonderful place in a thunder and lightning storm.”
+
+“Why?” asked Tom, curiously.
+
+“Because lightning would be powerfully attracted here by the presence
+of the metal. In fact there is evidence that many of the peaks have been
+struck by lightning,” and the scientist showed curious, livid scars on
+the stone faces of the peaks within sight.
+
+“Then this is a good place to stay away from in a storm,” observed Mr.
+Damon. “However, we won't worry about that now. If this is the landmark
+Mr. Jenks was searching for, then we must be in the vicinity of Phantom
+Mountain.”
+
+“I think we are,” declared the diamond seeker. “Probably it is within
+sight now, but there are so many peaks, and this is such a wild and
+desolate part of the country that we may have trouble in locating it.”
+
+“We've got to make a beginning, anyhow,” decided Tom, “and the sooner
+the better. Come, we'll make up our camping kits, and start out.”
+
+It was something to know that they were on the right trail, and it was a
+relief to be able to busy oneself, and not be aimlessly searching for a
+mysterious landmark. They all felt this, and soon the airship was taken
+to a secluded part of the valley, where it was well hidden from sight in
+a grove of trees.
+
+Tom and Mr. Damon then served a good meal, and preparations were made
+to start on their search among the mountains--a search which they hoped
+would lead them to Phantom Mountain, and the cave of the diamond makers.
+
+The tent which would afford them shelter was in sections, and could
+be laced together. They carried food, compressed into small packages,
+coffee, a few cooking utensils; and each one had a gun, Tom carrying a
+combination rifle and shotgun, for game.
+
+“We can't live very high while we're on the trail,” said the young
+inventor, “but it won't be much worse than it was on Earthquake Island.
+Are we all ready?”
+
+“I guess so,” answered Mr. Damon. “How long are we going to be away?”
+
+“Until we find the diamond makers!” declared Tom, firmly.
+
+Shouldering their packs, the adventurers started off. Tom turned for a
+last look at his airship, dimly seen amid the trees. Would he ever come
+back to the Red Cloud? Would she be there when he did return? Would
+their quest be successful? These questions the lad asked himself, as he
+followed his companions along the rocky trail.
+
+“Perhaps we can find the road by which these men go in and out of the
+cave,” suggested Mr. Damon, when they had gone on for several miles.
+
+“I fancy not,” replied Mr. Jenks. “They probably take great pains to
+hide it. I think though, that our best plan will be to go here and
+there, looking for the entrance to the cave. I believe I would remember
+the place.”
+
+“But why can't you follow the directions given by the miner who told you
+about Phantom Mountain?” asked Mr. Damon.
+
+“Because his talk was too indefinite,” answered Mr. Jenks. “He was so
+frightened by seeing what he believed to be a ghost, that he didn't take
+much notice of the location of the place. All he knows is that Phantom
+Mountain is somewhere around here.”
+
+“And we've got to hunt until we find it; is that the idea?” asked Mr.
+Parker.
+
+“Or until we see the phantom,” added Tom, in a low voice.
+
+“Bless my topknot!” exclaimed Mr. Damon. “You don't mean to say you
+expect to see that ghost; do you Tom?”
+
+“Perhaps,” answered the young inventor, and he did not add something
+else of which he was thinking. For Tom had a curious theory regarding
+the phantom.
+
+They tramped about the remainder of that day. Toward evening Tom shot
+some birds, which made a welcome addition to their supper. Then the tent
+was put together, some spruce and hemlock boughs were cut to make a soft
+bed, and on these, while the light of a campfire gleamed in on them, the
+adventurers slept.
+
+Their experience the following day was similar to the first. They saw no
+evidence of a large cave such as Mr. Jenks had described, nor were there
+any traces of men having gone back and forth among the mountains, as
+might have been expected of the diamond makers, for, as Mr. Jenks had
+said, they made frequent journeys to the settlement for food, and other
+supplies.
+
+“Well, I haven't begun to give up yet,” announced Tom, on the third day,
+when their quest was still unsuccessful. “But I think we are making one
+mistake.”
+
+“What is that?” inquired Mr. Jenks.
+
+“I think we should go up higher. In my opinion the cave is near the top
+of some peak; isn't it, Mr. Jenks?”
+
+“I have that impression, though, as you know, I never saw the outside of
+it. Still, it might not be a bad idea to ascend some of these peaks.”
+
+Following this suggestion, they laid their trail more toward the sky,
+and that night found them encamped several thousand feet above the
+sea-level. It was quite cool, and the campfire was a big one about which
+they sat after supper, talking of many things.
+
+Tom did not sleep well that night. He tossed from side to side on the
+bed of boughs, and once or twice got up to replenish the fire, which had
+burned low. His companions were in deep slumber.
+
+“I wonder what time it is?” mused Tom, when he had been up the third
+time to throw wood on the blaze. “Must be near morning.” He looked at
+his watch, and was somewhat startled to see that it was only a little
+after twelve. Somehow it seemed much later.
+
+As he was putting the timepiece back into his pocket the lad looked
+around at the dark and gloomy mountains, amid which they were encamped.
+As his gaze wandered toward the peak of the one on the side of which the
+tent was pitched, he gave a start of surprise.
+
+For, coming down a place where, that afternoon, Tom had noticed a sort
+of indefinite trail was a figure in white. A tall, waving figure, which
+swayed this way and that--a figure which halted and then came on again.
+
+“I wonder--I wonder if that can be a wisp of fog?” mused the young
+inventor. He rubbed his eyes, thinking it might be a swirling of the
+night mist or a defect of vision. Then, as he saw more plainly, he
+noticed the thing in white rushing toward him.
+
+“It's the phantom--the phantom!” cried Tom, aloud. “It's the thing the
+miner saw! We're on Phantom Mountain now!”
+
+
+
+
+CHAPTER XIV--WARNED BACK
+
+
+Tom's cries awakened the sleepers in the tent. Mr. Damon was the first
+to rush out.
+
+“Bless my nightcap, Tom!” he cried. “What is it? What has happened? Are
+we attacked by a mountain lion?”
+
+For answer the young inventor pointed up the mountain, to where, in the
+dim light from a crescent moon, there stood boldly revealed, the figure
+in white.
+
+“Bless--bless my very existence!” cried the odd man. “What is it, Tom?”
+
+“The phantom,” was the quiet answer. “Watch it, and see what it does.”
+
+By this time Mr. Jenks and Mr. Parker had joined Tom and Mr. Damon.
+The four diamond seekers stood gazing at the apparition. And, as they
+looked, the thing in white, seemingly too tall for any human being, slid
+slowly forward, with a gliding motion. Then it raised its long, white
+arms, and waved them threateningly at the adventurers.
+
+“It's motioning us to go back,” said Mr. Parker in an awed whisper. “It
+doesn't want us to go any farther.”
+
+“Very likely,” agreed Tom, coolly. “But we're not going to be frightened
+by anything like that; are we?”
+
+“Not much!” exclaimed Mr. Jenks. “I expected this. A ghost can't drive
+me back from getting my rights from those scoundrels!”
+
+“Suppose it uses a revolver to back up its demand?” asked the scientist.
+
+“Wait until it does,” answered Mr. Jenks. But the figure in white
+evidently had no such intentions. It came on a little distance
+farther, still waving the long arms threateningly, and then it suddenly
+disappeared, seeming to dissolve in the misty shadows of the night.
+
+“Bless my suspenders!” cried Mr. Damon. “That's a very strange
+proceeding! Very strange! What do you make of it, Tom?”
+
+“It is evidently some man dressed up in a sheet,” declared Mr. Jenks. “I
+expected as much.”
+
+“The work of those diamond makers; do you think?” continued Mr. Damon.
+
+“I believe so,” answered Tom, slowly, for he was trying to think it out.
+“I believe they are the cause of the phantom, though I don't know that
+it's a man dressed in a sheet.”
+
+“Why isn't it?” demanded Mr. Jenks.
+
+“Because it was too tall for a man, unless he's a giant.”
+
+“He may have been on stilts,” suggested Mr. Parker.
+
+“No man on stilts could walk along that way,” declared Tom, confidently.
+“He glided along too easily. I am inclined to think it may be some sort
+of a light.”
+
+“A light?” queried Mr. Damon.
+
+“Yes, the diamond makers may be hidden in some small cave near here, and
+they may have some sort of a magic lantern or a similar arrangement, for
+throwing a shadow picture. They could arrange it to move as they liked,
+and could cause it to disappear at will. That, I think, is the ghost we
+have just seen.”
+
+“But the diamond makers have only been in this mountain recently,”
+ objected Mr. Jenks, “and the phantom was here before them. In fact, that
+was what gave the place its name.”
+
+“That may be,” admitted the lad. “There are many places that have the
+name of being haunted, but no one ever sees the ghost. It is always some
+one else, who has heard of some one who has seen it. That may have been
+the case here. I grant that this place may have been called 'Phantom
+Mountain' for a number of years, due to the superstitious tales of
+miners. The diamond makers came along, found the conditions just right
+for their work, and adopted the ghost, so to speak. As there wasn't any
+real spirit they made one, and they use it to scare people away. I think
+that's what we've just seen, though I may be wrong in my theory as to
+what the phantom is.”
+
+“Well, it's gone now, at any rate,” said Mr. Jenks, “and I think we'd
+better get back inside the tent. It's cold out here.”
+
+“Aren't some of us going to stand guard?” demanded Mr. Damon.
+
+“What for?” asked Mr. Jenks.
+
+“Why--er--bless my key-ring! Suppose that ghost takes a notion to come
+down here, and use his gun, as he did on the miners?”
+
+“I don't believe that will happen,” remarked Tom. “The diamond makers,
+if the white thing had anything to do with them, have given us a
+warning, and I think they'll at least wait until morning to see how we
+heed it.”
+
+“We aren't going to heed it!” burst out Mr. Jenks. “I'm going to go
+right ahead and find that cave where they make diamonds!”
+
+“And we're with you!” exclaimed Tom. “We'll have a good fire going the
+rest of the night, and that may keep intruders away. In the morning
+we'll begin our search, and we'll go up the trail where we saw the white
+figure.”
+
+A big pile of wood had been collected for the fire, and Tom now piled
+some logs and branches on the blaze. It would last for some time now,
+and the adventurers, still talking of the “ghost” went back into the
+tent. It was over an hour before they all got to sleep again, and Mr.
+Jenks and Mr. Damon took turns in getting up once or twice during the
+remainder of the night to replenish the fire.
+
+Morning dawned without anything further having occurred to disturb them,
+and, after a hearty breakfast, to which Tom added some fish he caught in
+a nearby mountain stream, they set off up the trail on Phantom Mountain.
+
+They had left their tent standing, as they proposed making that spot
+their headquarters until they located the cave they were seeking. What
+their course would be after that would depend on the circumstances.
+
+If they had expected to have an easy task locating the cavern in which
+Mr. Jenks had seen diamonds made, the adventurers were disappointed. All
+that day they tramped up and down the mountain, looking for some secret
+entrance, but none was disclosed. The higher they went up the great
+peak, the fainter became the trail, until, at length it vanished
+completely.
+
+But this was not to be wondered at, since it was on solid rock, in which
+no footsteps would leave an impression.
+
+“They never brought you up here in a wagon, Mr. Jenks,” decided Tom,
+when he saw how steep the place was.
+
+“I'm inclined to think so myself,” admitted the diamond man. “They must
+have reached the cave from some other way. As a matter of fact, I walked
+some distance after getting out of the vehicle, before we got to the
+cavern. But, even at that, I don't believe we came this way.”
+
+“Yet the phantom was here,” persisted Tom, “and I'm convinced that the
+cave is in this neighborhood. It's up to us to find it!”
+
+But they searched the remainder of that day in vain, and as night was
+coming on, they made their way back to the camp. As Tom, who was in
+the lead, approached the tent, he saw something black fastened to the
+entrance.
+
+“Hello!” he cried. “Some one's been here. That wasn't on the tent when
+we left this morning.”
+
+“What is it?” asked Mr. Damon.
+
+“A black piece of paper, written on with white ink,” replied the lad. He
+was reading it, and, as he perused it a look of surprise came over his
+face.
+
+“Listen to this!” called Tom. “It's evidently from the diamond makers.”
+
+Holding up the black paper, on which the white writing stood out in bold
+relief Tom read aloud:
+
+
+“Be warned in time! Go back before it is too late! You are near to
+death! Go back!”
+
+
+“Bless my shoelaces!” cried Mr. Damon. “This is getting serious.”
+
+
+
+
+CHAPTER XV--THE LANDSLIDE
+
+
+Gathered about the young inventor, the three men looked at the warning.
+The writing was poor, and it was evident that an attempt had been made
+to disguise it. But there was no misspelling of words, and there were no
+rudely drawn daggers, or bloody hands or anything of that sort. In fact,
+it was a very business-like sort of warning.
+
+“Rather odd,” commented Mr. Jenks. “Black paper and white ink.”
+
+“White ink is easy enough to make,” stated Mr. Parker. “I fancy they
+wanted it as conspicuous as possible.”
+
+“Yes,” agreed Tom, “and this warning, together with the antics of the
+thing in white last night, shows that they are aware of our presence
+here, and perhaps know who we are. We will have to be on our guard.”
+
+“Do you think that fellow Munson, whom we left in the forest, could have
+gotten here and warned them?” asked Mr. Damon.
+
+“It's possible,” admitted Tom, “but now let's see if the person who
+pinned this warning on our tent took any of our things.”
+
+A hasty examination, however, showed that nothing had been disturbed,
+and Tom and Mr. Damon were soon getting supper ready, everyone talking,
+during the progress of the meal, about the events of the day, and the
+rather weird culmination of it.
+
+“Well, we haven't had a great deal of success--so far,” admitted Tom, as
+they sat about the fire, in the fast gathering dusk. “I think, perhaps,
+we'd better try on the other side of the mountain to-morrow. We've
+explored this side pretty thoroughly.”
+
+“Good idea,” commented Mr. Jenks. “We'll do it, and move our camp. I
+only hope those fellows don't find our airship and destroy it. We'll
+have a hard time getting back to civilization again, if we have to walk
+all the way.”
+
+This contingency caused Tom some uneasiness. He did not like to think
+that the unscrupulous men might damage the Red Cloud, that had been
+built only after hard labor. But he knew he could accomplish nothing by
+worrying, and he tried to dismiss the matter from his mind.
+
+They rather expected to see the thing in white again that night, but it
+did not appear, and morning came without anything having disturbed their
+heavy sleep, for they were tired from the day's tramp.
+
+It took them the greater part of the day to make a circuit of the base
+of Phantom Mountain in order to get to a place where a sort of trail led
+upward.
+
+“It's too late to do anything to-night,” decided Tom, as they set up the
+tent. “We'll rest, and start the first thing in the morning.”
+
+“And the ghost isn't likely to find us here,” added Mr. Damon. “Where
+are you going, Mr. Parker?” he asked, as he saw the scientist tramping a
+little way up the side of the mountain.
+
+“I am going to make some observations,” was the answer, and no one paid
+any more attention to him for some time. Supper was nearly ready when
+Mr. Parker returned. His face wore a rather serious air, and Mr. Damon,
+noting it, asked laughingly:
+
+“Well, did you discover any volcanoes, that may erupt during the night,
+and scare us to death?”
+
+“No,” replied Mr. Parker, calmly, “but there is every indication that we
+will soon have a terrific electrical storm. From a high peak I caught a
+glimpse of one working this way across the mountains.”
+
+“Then we'd better fasten the tent well down,” called Tom. “We don't want
+it to blow away.”
+
+“There will not be much danger from wind,” was Mr. Parker's opinion.
+
+“From what then?” asked Mr. Jenks.
+
+“From the discharges of lightning among these mountain peaks, which
+contain so much iron ore. We will be in grave danger.”
+
+The fact that the scientist had not always made correct predictions was
+not now considered by his hearers, and Tom and the two men gazed at Mr.
+Parker in some alarm.
+
+“Is there anything we can do to avoid it?” asked Mr. Jenks.
+
+“The only thing to do would be to leave the mountain,” was the answer,
+“and, as the iron ore extends for miles, we can not get out of the
+danger zone before the storm will reach us. It will be here in less than
+half an hour.”
+
+“Then we'd better have supper,” remarked Tom, practically, “and get
+ready for it. Perhaps it may not be as bad as Mr. Parker fears.”
+
+“It will be bad enough,” declared the gloomy scientist, and he seemed to
+find pleasure in his announcement.
+
+The meal was soon over, and Tom busied himself in looking to the guy
+ropes of the tent, for he feared lest there might be wind with the
+storm. That it was coming was evident, for now low mutterings of thunder
+could be heard off toward the west.
+
+Black clouds rapidly obscured the heavens, and the sound of thunder
+increased. Fitful flashes of lightning could be seen forking across the
+sky in jagged chains of purple light.
+
+“It's going to be a heavy storm,” Tom admitted to himself. “I hope
+lightning doesn't strike around here.”
+
+The storm came on rapidly, but there was a curious quietness in the air
+that was more alarming than if a wind had blown. The campfire burned
+steadily, and there was a certain oppressiveness in the atmosphere.
+
+It was now quite dark, save when the fitful lightning flashes came,
+and they illuminated the scene brilliantly for a few seconds. Then, by
+contrast, it was blacker than ever.
+
+Suddenly, as Tom was gazing up toward the peak of Phantom Mountain, he
+saw something that caused him to cry out in alarm. He pointed upward,
+and whispered hoarsely:
+
+“The ghost again! There's our friend in white!”
+
+The others looked, and saw the same weird figure that had menaced them
+when they were encamped on the other side of the peak.
+
+“They must have followed us,” said Mr. Jenks, in a low voice.
+
+Slowly the figure advanced, It waved the long white arms, as if in
+warning. At times it would be only dimly visible in the blackness, then,
+suddenly it would stand out in bold relief as a great flash of fire
+split the clouds.
+
+The thunder, meanwhile, had been growing louder and sharper, indicating
+the nearer approach of the storm. Each lightning flash was followed in a
+second or two, by a terrific clap. Still there was no wind nor rain, and
+the campfire burned steadily.
+
+All at once there was a crash as if the very mountain had split asunder,
+and the adventurers saw a great ball of purple-bluish fire shoot down,
+as if from some cloud, and strike against the side of the crag, not a
+hundred feet from where stood the ghostly figure in white.
+
+“That was a bad one,” cried Mr. Damon, shouting so as to be heard above
+the echoes of the thunderclap.
+
+Almost as he spoke there came another explosion, even louder than the
+one preceding. A great ball of fire, pear shaped, leaped for the same
+spot in the mountain.
+
+“There's a mass of iron ore there!” yelled Mr. Parker. “The lightning is
+attracted to it!”
+
+His voice was swallowed up in the terrific crash that followed, and,
+as there came another flash of the celestial fire, the figure in
+white could be seen hurrying back up the mountain trail. Evidently the
+electrical storm, with lightning bolts discharging so close, was too
+much for the “ghost.”
+
+In another instant it looked as if the whole place about where the
+diamond seekers stood, was a mass of fire. Great forked tongues of
+lightning leaped from the clouds, and seemed to lick the ground. There
+was a rattle and bang of thunder, like the firing of a battery of guns.
+Tom and the others felt themselves tingling all over, as if they had
+hold of an electrical battery, and there was a strong smell of sulphur
+in the air.
+
+“We are in the midst of the storm!” cried Mr. Parker. “We are standing
+on a mass of iron ore! Any minute may be our last!”
+
+But fate had not intended the adventurers for death by lightning. Almost
+as suddenly as it had begun, the discharge of the tongues of fire ceased
+in the immediate vicinity of our friends. They stood still--awed--not
+knowing what to do.
+
+Then, once more, came a terrific clap! A great mass of fire, like some
+red-hot ingot from a foundry, was hurled through the air, straight at
+the face of the mountain, and at the spot where the figure in white had
+stood but a few minutes before.
+
+Instantly the earth trembled, as it had at Earthquake Island, but it was
+not the same. It was over in a few seconds. Then, as the diamond seekers
+looked, they saw in the glare of a score of lightning flashes that
+followed the one great clap, the whole side of the mountain slip away,
+and go crashing into the valley below.
+
+“A landslide!” cried Mr. Parker. “That is the landslide which I
+predicted! The lightning bolt has split Phantom Mountain!”
+
+
+
+
+CHAPTER XVI--THE VAST CAVERN
+
+
+For a time the roiling, slipping, sliding and tumbling of the mass of
+earth and stones, down the side of the mountain, effectually drowned
+all other sounds. Even the thunder was stilled, and though Tom and his
+companions called to one another in terror, their voices could not rise
+above that terrific tumult.
+
+Finally, when they found that the direction of the slide was away from
+their tent, and that they were not likely to be engulfed, they grew more
+calm.
+
+Gradually the noise subsided. The great boulders had rolled to the
+bottom of the valley, and now only a mass of earth and stones was
+sliding down. Even this stopped in about five minutes, and, as though
+satisfied with what it had done, the electrical storm passed. Not a drop
+of rain had fallen.
+
+“Bless my shirt studs!” exclaimed Mr. Damon, who was the first to speak
+after the din had quieted. “Bless my soul! But that was awful!”
+
+“It was just what I expected,” said Mr. Parker, calmly. “I knew, from
+my observations, that we were in a region where landslides and terrific
+electrical storms may be expected at any time. I fully looked for this.”
+
+“Well,” remarked Mr. Jenks, rather sarcastically, “I hope it came up to
+your expectations, Mr. Parker.”
+
+“Oh, fully,” was the answer, “though I wish it could have happened
+in daylight, so that I could better have observed certain phenomena
+regarding the landslide. They are very interesting.”
+
+“At a distance,” admitted Tom, with a laugh of relief. “Well, I'm glad
+it's over, though we'll have to wait until morning to see what damage
+has been done. Lucky we weren't struck by lightning. I never saw such
+bolts!”
+
+“Me, either!” declared Mr. Damon. “This mountain seems to attract them.”
+
+“It is like a magnet,” said Mr. Parker. “I think I shall be able to make
+some fine observations here.”
+
+“If we live through it,” murmured Mr. Jenks.
+
+They watched the play of lightning about a distant bank of clouds,
+but the storm was now far away, only a faint rumbling of thunder being
+heard.
+
+“I'm wondering what happened to the phantom,” said Tom, after a pause.
+“Seems to me he was right in that track of the storm.”
+
+“Do you think it was a 'he'?” asked Mr. Jenks.
+
+“I think we'll find that it's some sort of a man,” answered the young
+inventor. “We may find out very soon, now. I've changed my theory about
+the ghost being reflections of light.”
+
+“How's that?” Mr. Damon wanted to know.
+
+“Well, I think we are on the side of Phantom Mountain where the diamond
+cave is,” went on the lad. “The fact that the phantom appeared here,
+soon after we arrived, shows that the men kept close track of our
+movements. It also shows, I think, that the phantom did not have to
+travel far to be on the spot, whereas we had to make quite a trip to get
+around the base of the mountain. I think the cave is up there,” and
+Tom pointed toward the spot where the weird figure had been last seen,
+before the storm drove it back.
+
+“There may be two phantoms,” suggested Mr. Jenks. “They may keep one on
+this side of the mountain, and one on the other, to warn intruders away.
+
+“It's possible,” admitted Tom. “Well, we'll see how things look in the
+morning, when we'll take up our march again, and go up the mountain.
+We'll reach the top, if possible, which we couldn't do from the other
+side, as it was too steep.”
+
+“I hope we shall be able to go forward in the morning,” came from Mr.
+Jenks.
+
+“What do you mean?” asked the lad, struck by a peculiar significance in
+the diamond man's tones.
+
+“Why, that landslide may have opened a great gully in the side of
+Phantom Mountain, which will prevent us from passing. It was a terrific
+lot of earth and stones that slid away,” answered Mr. Jenks.
+
+“It certainly was,” agreed Mr. Parker. “I would not be surprised if
+the mountain was half destroyed, and it may be that the diamond cave no
+longer exists.”
+
+“Not very cheerful, to say the least,” murmured Mr. Jenks to Tom, and,
+as it was getting quite chilly, following the storm, they went inside
+the tent.
+
+Tom could hardly wait for daylight, to get up and see what havoc the
+landslide had wrought. As soon as the first faint flush of dawn showed
+over the eastern peaks, he hurried from the tent. Mr. Damon heard him
+arise, and followed.
+
+A curious scene met their eyes. All about were great rocks rent and torn
+by the awful power of the lightning. The fronts of the stone cliffs
+were scarred and burned by the electrical fire, and fantastic markings,
+grotesque faces, and leering animals seemed to have been drawn by some
+gigantic artist who used a bolt from heaven for his brush.
+
+But the eyes of Tom and Mr. Damon took all this in at a glance, and then
+their gaze went forward to where the avalanche had torn away a great
+part of the mountain.
+
+“Whew! I should say it was a landslide!” cried Tom.
+
+“Bless my wishbone, yes!” agreed Mr. Damon.
+
+Below them, in the valley, lay piled immense masses of earth and stones.
+Boulders were heaped up on boulders, and rocks upon rocks, being tossed
+about in heaps, strung about in long ridges, and swirled about in
+curves, as though some cyclone had toyed with them after the lightning
+flash had tossed them there.
+
+“But the mountain isn't half gone,” said Tom, as his eyes took in what
+was left of the phantom berg. “I guess it will take a few more bolts
+like that one, to put this hill out of business.”
+
+Though the landslide had been a great one, the larger part of the
+mountain still stood. An immense slice had been taken from one side, but
+the summit was untouched.
+
+“And there's where the diamond cave is!” cried Tom, pointing to it.
+
+“I think so myself,” agreed Mr. Jenks, who came from the tent at that
+moment, and joined the lad and Mr. Damon. “I think we shall find the
+cave somewhere up there. We must start for it, as soon as we have eaten,
+and we may reach it by night.”
+
+The three stood gazing up toward the summit of the great mountain.
+Suddenly, as the sun rose higher in the heavens, it sent a shaft of rosy
+light on the face of the berg that had been scarred by the landslide.
+Tom Swift uttered an exclamation, and pointed at something.
+
+“See!” he cried. “Look where the trail is--the trail down which the
+phantom must have come. It is on the edge of a cliff now!”
+
+They looked, and saw that this was so. The increasing light had just
+revealed it to them. When the lightning bolt had torn away a great
+portion of the mountain it had cut sheer down for a great depth and
+when the earth and stones fell away they left a narrow pathway, winding
+around the mountain, but so near the edge of a great chasm, that there
+was room but for one person at a time to walk on that footway. The
+uncertain trail up Phantom Mountain had all but been destroyed.
+
+“The way up to the peak is by that path, now,” spoke Tom, in a low
+voice.
+
+“Bless my soul!” cried Mr. Damon. “It's as much as a man's life is worth
+to attempt it. If he got dizzy, he'd topple over, and fall a thousand
+feet. Dare we risk it?”
+
+“It's the only way to get up,” went on Tom. “It's either that way, or
+not at all. We've tried the other side without success. We must go up
+this way--or turn back.”
+
+“Then we'll go up!” cried Mr. Jenks. “It may not be as dangerous as it
+looks from here.”
+
+But it was even more dangerous than it appeared, when they went part way
+up it after a hasty breakfast. The trail was a mere ledge of rock now,
+and in some places, to get around a projecting edge of the mountain,
+they had to stand with their backs to the dizzy depths at their feet,
+and with both arms outstretched work their way around to where the trail
+was wider.
+
+“Shall we risk it?” asked Tom, when they had tried the way, and found
+it so dangerous. “We can't take anything with us--even our guns, for
+we couldn't carry them, and if we reach the mouth of the cave, and find
+those men there--”
+
+He paused significantly. The adventurers looked at one another. The
+search for the diamond makers was becoming more and more dangerous.
+
+“I say let's go on!” decided Mr. Damon, suddenly. “We want to locate
+that cave, first of all. Perhaps, when we do find it, we may see some
+easier way of getting to it than this. And if those diamond makers do
+attack us--well, I don't believe they'll shoot defenseless men, and they
+may listen to reason, and give Mr. Jenks his rights--tell him how to
+make diamonds in return for the money he gave them.”
+
+“I don't believe those scoundrels will listen to reason,” replied the
+diamond man, “but I agree with Mr. Damon that we ought to go on. We may
+find some other means of reaching the cave--if we can discover it, and
+we'll take a chance with the men.”
+
+“Forward it is, then!” cried Tom. “I have a revolver, and I can supply
+one of you gentlemen with another. They may come in useful in an
+emergency. Let's go back to camp, take a little lunch in our pockets,
+and try to scale the mountain.”
+
+They were soon on their way up the dizzy path once more, and, as they
+advanced, they found it growing more and more dangerous. In some places
+they found it almost impossible to get around certain corners, where
+there was barely room for their feet. As Tom remarked grimly, a fat man
+never could have done it. Fortunately they were all comparatively thin,
+for their hard work, and not too abundant food, since they had left the
+airship, had reduced their weight.
+
+Up and up they went, higher and higher, sometimes finding the path wide
+enough for two to walk abreast, and again seeing it narrow almost to
+a ribbon. They hardly dared look down into the chasm at their left--a
+chasm filled, in part, with the rocks and boulders tossed into it by the
+lightning bolt.
+
+Tom was in the lead, and had just made a dangerous turn around a
+shoulder of rock--one of those places where he had to extend both arms,
+and fairly hug the cliff before he could get around.
+
+But, when he had made it, and found himself on a broad pathway, cut
+in the living rock, he gave a great shout--a shout that caused his
+companions to hasten to his side. They found the young inventor pointing
+to a clump of bushes and small trees.
+
+But it was not the shrubbery that Tom desired to call to their
+attention. They saw that in an instant, for, dimly seen through the
+leaves, was something black, and, as they looked more closely, they saw
+that it was a great hole in the side of the mountain--a vast cavern,
+opening like a tunnel.
+
+“The cave! The cave!” cried Tom. “The diamond makers' cave!”
+
+Hardly had he spoken than two men, each one carrying a gun, showed
+themselves in the mouth of the cavern, and, instant later they both ran
+toward the little party of adventurers.
+
+
+
+
+CHAPTER XVII--THE PHANTOM CAPTURED
+
+
+Surprise held Tom and his friends almost spellbound for the moment.
+The young inventor's hand went toward the pocket where he carried his
+revolver. Mr. Jenks, who had the only other weapon, sought to draw it,
+but he was stopped by a gesture of one of the two men with guns.
+
+“Hold on, strangers!” the man cried. “I know what you're up to! Better
+not try to draw anything--it might not be healthy. Now, then, who are
+you, and what do you want?”
+
+The question came rather as a surprise, at least to Tom and Mr. Jenks.
+They had taken it for granted that these men--if they were the diamond
+makers--would know Mr. Jenks, and guess at his errand in coming back
+to Phantom Mountain. But, it seemed, that they took them all for casual
+strangers.
+
+No one answered for a moment. Tom caught the eye of Mr. Jenks, and there
+was a look of hope in it. If ever there was a time for strategy, it was
+now. Evidently Munson, the stowaway on the airship, had not yet been
+able to send a warning to his confederates. And neither of the two men
+recognized Mr. Jenks as the man who had been defrauded of his rights.
+It might be possible to conceal the real object of the adventurers until
+they had time to formulate a plan of action.
+
+“Well,” exclaimed the man with the gun, impatiently, “I ask you folks a
+question. What do you want?”
+
+Fortunately, neither Mr. Damon nor Mr. Parker replied. The former
+because he deferred to Tom and Mr. Jenks, and the scientist because he
+was busy inspecting some curious rocks he picked up. As it turned out
+this was the luckiest thing he could have done. It lent color to what
+Mr. Jenks said a moment later.
+
+“What are you doing up here?” demanded the man again. “Don't you know
+this is private property?”
+
+“We--we were just looking around,” answered Mr. Jenks, which was true
+enough; as far as it went.
+
+“Prospecting,” added Tom.
+
+“After gold?” demanded the second man, suspiciously.
+
+“We'd be glad to find some,” retorted the lad. At that moment Mr. Parker
+began breaking off bits of rock with a small geologist's hammer which he
+carried. The men with the guns looked at him.
+
+“So you think you'll find gold up here?” asked the one who had first
+spoken.
+
+“Is there any?” inquired Tom, trying to make his voice sound eager.
+
+“Nary a bit, strangers,” was the answer, and the two men laughed
+heartily. “Now, we don't want to seem harsh,” went on the man who seemed
+to be the spokesman, “but you'd better get away from here. This is
+private ground, and dangerous too--how'd you ever get up the trail--we
+heard it was destroyed.”
+
+“There is still a narrow path,” said Mr. Jenks. “We came up that--the
+lightning and landslide haven't left much of it, though.”
+
+Mr. Parker looked quickly up from the rocks at which he was tapping with
+his small hammer. “You have terrific lightning up here,” he said. “I am
+much interested in it, from a scientific standpoint. I predict that some
+day the entire mountain will be destroyed by a blast from the sky.”
+
+“I hope it won't be right away,” spoke one of the men. “Now I guess you
+folks had better be leaving while there's a path left to go down by.”
+
+“Might I ask,” broke in Mr. Parker, as calmly as though he was lecturing
+to a class of students, “might I ask if you have noticed any peculiar
+effect of the lightning up here on the summit of the mountain? Does it
+fuse and melt rocks, so to speak?”
+
+“What's that?” cried the spokesman, with a sudden flash of anger. The
+two men looked at each other.
+
+“I wanted to know, merely for scientific reasons, whether the lightning
+up here ever melted rocks?” repeated Mr. Jenks.
+
+“Well, whether it's for scientific reasons or for any other, I'm not
+going to answer you!” snapped the man. “It's none of your affair what
+the lightning does up here. Now you'd all better 'vamoose'--clear out!”
+
+“All right--we'll go,” said Tom, quickly, at the same time motioning to
+Mr. Jenks to agree with him. The eyes of the young inventor were
+roving about. He saw what looked like a second trail, leading down the
+mountain, from the far side of the cave. He was convinced now that there
+was another way to get to it. Possibly they might find it. At any rate
+nothing more could be done now. They must go back, for the cavern was
+too well guarded to attempt to enter it by force--at least just yet.
+
+“Yes, we'll go back,” assented Mr. Jenks.
+
+Mr. Parker was tapping away at the rocks. He looked toward the black
+mouth of the big cave. On what corresponded to the roof of it, some
+distance back from the entrance, he saw a slender metal rod sticking up
+into the air.
+
+“May I ask if that's a lightning rod?” he inquired innocently. “If
+it is, I should like to ask about its action in a mountain that is so
+impregnated with iron ore.
+
+“You may ask until you get tired!” cried the spokesman, again showing
+unreasoning anger, “but you'll get no answer from us. Now get away from
+here before we do something desperate. You're on private ground and
+you're not wanted. Clear out while you have the chance.”
+
+There was no help for it. Slowly our friends turned and began to go
+down the dangerous trail. They were soon out of sight of the two men who
+stood before the cave, with their guns ready, but neither Tom nor any of
+his companions spoke for some time.
+
+When they had rounded one of the most dangerous turns the young inventor
+sat down to rest, an example followed by the others.
+
+“Well,” asked Tom, “do you think those are some of the diamond makers,
+Mr. Jenks?”
+
+“I certainly do, though I never saw those two men before. If I could
+once get inside the cave, I could tell whether or not it was the one
+where I was practically held a prisoner. But I'm sure it is. I know some
+of the men used to go off every day with guns, and not come back until
+night. I have no doubt they were on guard, just as these two are. And,
+also, I think I heard them speak of a second entrance to the cavern. The
+one we just saw may not be the main one, through which I was taken.”
+
+“I believe we are on the right track,” ventured Mr. Damon, “but we will
+either have to go up there after dark, which will be risky, on account
+of the narrow trail, or else we will have to find some other path.”
+
+“The last would be better,” spoke Tom.
+
+“That rod of metal sticking up on top of the cave interested me,” said
+the scientist. “Did you hear anything of that when you were here before,
+Mr. Jenks?”
+
+“No. Probably that is only a lightning rod, or it may be a staff for a
+signal flag. But what surprises me is that those men didn't suspect
+that we were seeking to discover their secret. They took us for ordinary
+prospectors.”
+
+“So much the better,” remarked Tom. “We have a chance now of getting
+inside that cave. But we will have to go back to camp, and make other
+plans. And we must hurry, or it will be dark before we get there.”
+
+They hastened their steps, pausing only briefly to eat some of the lunch
+they had brought along, and to drink from a spring that bubbled from the
+side of the mountain. It was getting dusk when they got back to their
+tent. They found nothing disturbed.
+
+“I wonder if we'll see that phantom again to-night?” ventured Tom, as
+they were sitting about the campfire a little later.
+
+“Probably not,” remarked Mr. Jenks. “I don't believe the ghost will
+venture down the dangerous trail after dark, and the gang may think
+that the warning given us by the two men on guard at the cave will be
+sufficient. But if we don't leave here by to-morrow I think we will have
+another visit from the thing in white.”
+
+It was about an hour after this when Tom was collecting some wood in a
+pile nearer the fire, so as to have it ready to throw on, in case there
+was any alarm in the night, that he happened to look up toward the
+summit of the mountain. A slight noise, as of loose stones rolling down,
+attracted his attention, and, at first, he feared lest another landslide
+was beginning, but a moment later he saw what caused it.
+
+There, advancing down the steep and dangerous trail was the figure
+in white--the phantom. Instantly a daring plan came into Tom's head.
+Dropping the wood softly, he moved back out of the glare of the fire.
+
+“Mr. Jenks!” he called in a whisper.
+
+The diamond man, who was behind the tent, came toward Tom.
+
+“What is it?” he asked. Then, as he saw the ghostly visitor, he added:
+“Oh--the phantom again! What's it up to?”
+
+“The same thing,” replied Tom, “but it won't do it long, if my plan
+succeeds.”
+
+“What plan is that, Tom?”
+
+“I'm going to try to capture that--that man--or whatever it is. Will you
+help?”
+
+“Surely!”
+
+“Then let's work around behind it, while Mr. Damon and Mr. Parker come
+up from in front. We'll solve this part of the mystery, anyhow, if it's
+possible!”
+
+The two other men were soon told of the plan. Meanwhile the thing in
+white had advanced slowly, until within a few hundred feet of the camp.
+They could see now that it was no shaft of light, but some white body,
+shaped like a tall, thin man, draped in a white garment. The long arms
+waved to and fro. There was no semblance of a head.
+
+“You and Mr. Parker go right toward it, slowly, Mr. Damon,” advised
+Tom. “Mr. Jenks and I will make a circle, and get in back. Then, if it's
+anything alive we'll have it.”
+
+The “ghost” continued to advance. Tom and the diamond man stole off to
+one side, their buckskin moccasins making no sound. Mr. Damon and the
+scientist went boldly forward.
+
+This movement appeared to disconcert the spirit. It halted, waved the
+arms with greater vigor than before, and seemed to indicate to the
+adventurers that it was dangerous to advance. But Mr. Damon and Mr.
+Parker kept on. They wanted to give Tom and Mr. Jenks time enough to
+make the circuit.
+
+Suddenly the stillness of the night was broken by a low whistle. It was
+Tom's signal that he and Mr. Jenks were ready.
+
+“Come on! Run!” cried Mr. Damon.
+
+The scientist and the eccentric man leaped forward.
+
+The “ghost” heard the whistle, and heard the spoken words. The thing in
+white hesitated a moment, and then raised one arm. There was a flash of
+fire, and a loud report.
+
+“He's firing in the air!” cried Tom. “Come on, we have him now!”
+
+Undaunted by the display of firearms, Mr. Damon and Mr. Parker kept on.
+They could hear Tom and Mr. Jenks running up in back of the figure.
+The latter also heard this, and suddenly turned. Caught between the two
+forces of our friends, the “ghost” was at a loss what to do.
+
+The next instant Tom, who had distanced Mr. Jenks, made a flying tackle
+for the figure in white, and caught it around the legs. Very substantial
+legs they were, too, Tom felt--the legs of a man.
+
+“Wow!” yelled the “ghost,” as he went down in a heap, the revolver
+falling from his hand.
+
+“Come on!” cried Tom. “I have him!”
+
+His friends rushed to his aid. There was a confused mass of dark bodies,
+arms and legs mingled with something tall and thin, all in white.
+Suddenly the moon came from behind a cloud and they could see what they
+had captured--for captured the phantom was.
+
+It proved to be a rather small man, who wore upon his shoulders a
+framework of wood, over which some white cloth was draped. It had fallen
+off him when Tom made that tackle.
+
+“Well,” remarked the young inventor, as he sat on the struggling man's
+chest. “I guess we've got you.”
+
+“I rather guess you have, stranger,” was the cool reply.
+
+
+
+
+CHAPTER XVIII--BILL RENSHAW WILL HELP
+
+
+They were all panting from the exertion of the run up the mountain and
+the contest with the phantom--a phantom no longer--though, truth to
+tell, the struggle was not nearly so fierce as Tom had expected. He
+thought the “ghost” would put up a stiff fight.
+
+“Got any ropes to tie him with?” asked Mr. Damon, who was helping Tom
+hold the man down.
+
+“Ropes? You aren't going to tie me up are you, strangers?” asked the
+captive.
+
+“That's what we are!” exclaimed Mr. Jenks. “We've had trouble enough in
+this matter, and if I've got one of the gang, perhaps I can get some of
+the others, and have my rights. So tie him up, Tom, and we'll take him
+to camp.
+
+“Oh, you needn't go to all that trouble, strangers,” went on the man,
+calmly. “If one of you will get off my chest, and the other gentleman
+ease up on my stomach a bit, I'll walk wherever you want me, and not
+make any trouble. I haven't got a gun.”
+
+“Bless my gloves! But you're a cool one,” commented Mr. Damon, as he
+complied with the man's request, and got up from his stomach. “But look
+out for him, Tom. He had a gun, for he fired it in the air.”
+
+“He hasn't it now,” answered the young inventor. “I knocked it from his
+hand when I leaped for him.”
+
+“That's what you did,” assented the man, as he got up, while Tom kept a
+tight hold of him, as did Mr. Jenks. “What kind of a grizzly bear hug do
+you call that, anyhow, that you gave me?”
+
+“That was a football tackle,” explained Tom.
+
+“I allers heard that was a dangerous game!” remarked the former phantom
+simply. “Well, now you've got me, what are you going to do with me?”
+
+“Take you where we can have a good look at you,” replied Mr. Jenks, as
+he kicked aside the wooden framework, and the sheet which had made the
+“ghost” appear so tall. “So this is how you worked it; eh?”
+
+“Yep. That was the 'haunt' stranger. I made it myself, and it worked all
+right until you folks come along. I rather suspicioned from the first,
+when I played the trick over on 'tother side of the mountain, that you
+wouldn't be so easy to fool as most prospectors are.”
+
+“Oh, so you're the only ghost then?” asked Tom.
+
+“I'm the only one.”
+
+By this time they had reached the camp. Tom threw some light logs on the
+fire, which blazed up brightly. As the flames illuminated the face of
+their captive, Mr. Jenks looked at him, and cried out:
+
+“Why it's Bill Renshaw!”
+
+“That's me,” admitted the man who had played the part of the phantom,
+“and thunder-turtles! if it ain't Mr. Jenks who was once in the diamond
+cave with us. Whatever happened to you? I never heard. The others said
+you got tired and went away.”
+
+“They took me away--defrauded me of my rights!” declared Mr. Jenks,
+bitterly. “But I'll get them back! To think of Bill Renshaw playing the
+part of a ghost!”
+
+“They made me do it,” went on the man, somewhat dejectedly. “I wanted to
+be at work in the cave, but they wouldn't let me.”
+
+“Is this man one of the diamond makers?” asked Tom, in great surprise.
+
+“He is--one of the helpers, though I don't believe he knows the secret
+of making the gems,” explained Mr. Jenks. “He was one of the men in the
+cave when I was there before, and he and I struck up quite a friendship;
+didn't we, Renshaw?”
+
+“That's what, and there ain't no reason why we can't be friends now;
+that is unless you hold a grudge against me for firing at you. But I
+only shot in the air, to scare you away. Them's my instructions. I'm
+supposed to be on guard, and scare away strangers. I'm tired of the
+work, too, for I don't get my share, and those other fellows, in the
+cave, get all the money from the diamonds.”
+
+Tom Swift uttered an exclamation. A sudden plan had come to him. Quickly
+he whispered to Mr. Jenks:
+
+“Make a friend of this man if possible. He evidently is dissatisfied.
+Offer him a sum to show us another way into the cave, and we may yet
+discover the secret of the diamond makers.”
+
+“I will,” declared Mr. Jenks, quietly. Then, turning to Renshaw, he
+added:
+
+“Bill, come over here. I want to have a talk with you. Perhaps it will
+be to our mutual advantage.”
+
+He led the former phantom to one side, and for some time conversed
+earnestly with him. Mr. Jenks told the story of how he had been deceived
+by Folwell and the others who were at the head of the gang of diamond
+makers. The rich man related how they had taken his money, and, after
+promising to disclose the secret process to him, had broken faith, and
+had drugged him, afterward taking him out of the cave.
+
+“I want only my rights, and that for which I paid,” concluded Mr. Jenks.
+“Now, I gather that these men haven't treated you altogether fairly,
+Bill.”
+
+“Indeed they haven't. I helped 'em to the best of my ability, and all
+I get out of it is to stay out on this lonely side of the mountain,
+and play ghost. They owe me money, too, and they won't pay me, either,
+though they have lots, for they sold some diamonds lately.”
+
+“Then they are still making diamonds?” asked Mr. Jenks, eagerly. “Have
+you seen them? Do you know the secret?”
+
+“No, I don't know it, for they won't let me in on it. I'm always sent
+out of the cave just before they make the gems. But I know they've made
+some lately, and have sold 'em. I want my share.”
+
+“Look here!” exclaimed Mr. Jenks, quickly, wishing to strike while the
+iron was hot. “I'll make you a proposition. Show us how to get into that
+cave, unknown to the diamond makers, and I'll pay you twice what they
+agreed to. Is it a bargain?”
+
+Bill Renshaw considered a moment. Then he thrust out his hand, clasped
+that of Mr. Jenks, and exclaimed:
+
+“It is. I'll take you into the cave by an entrance that's seldom used.
+There are four ways to get in. The one where the two men drove you back
+is the rear one. The front one is on the other side of the mountain, but
+it's so well concealed that you'd never find it. But I can take you to
+one where you can get in, and those fellows will never know it. And,
+what's more, I'll help you if it comes to a fight!”
+
+“Good!” exclaimed Mr. Jenks. “I think we'll discover the secret of the
+diamond makers this time,” and he went to tell the others of the success
+of his talk. Bill Renshaw had been converted from an enemy into a
+friend, and the former phantom was now ready to lead Tom and the others
+into the secret cave.
+
+“We'll start in the morning,” decided Mr. Jenks, who, after many
+disappointments, at last saw success ahead of him.
+
+
+
+
+CHAPTER XIX--IN THE SECRET CAVE
+
+
+Tom Swift was up at break of day, and the others were not far behind
+him.
+
+“Now for the secret cave!” cried the young inventor as he gazed up
+the mountain, in the interior of which the mysterious band of men were
+making the diamonds.
+
+“Have you made any plans, Bill?” asked Mr. Jenks of the former phantom,
+who had cast his lot in with the adventurers. “What will be the best
+course for us to follow?”
+
+“You just leave it to me, Mr. Jenks,” was the answer. “I'll get you into
+the cave, and those fellows, who, I believe, are trying to do me out of
+my rights, as they did you out of yours, will never know a thing about
+it.”
+
+“Bless my finger-nails!” cried Mr. Damon. “That will be great! We can
+get in the cave, and watch them make the diamonds at our leisure.”
+
+“They don't make them every day,” explained Renshaw. “It seems they
+have to wait for certain occasions. Mostly they make the diamonds when
+there's a big storm.”
+
+“A big storm,” asked the scientist with a sudden show of interest.
+“Do you mean one of those electrical storms, such as we had the other
+night?”
+
+“That's it, Mr. Parker, though why they wait until there's a storm is
+more than I can tell.”
+
+“Perhaps they know that on such occasions no one will venture up the
+mountain,” spoke Mr. Damon.
+
+“No, it isn't that,” declared the scientist. “I think I am on the
+track of a great scientific discovery, and I will soon be able to make
+observations that will confirm it.”
+
+“Well, I'm going to make an observation right now,” said Tom, with a
+laugh. “I'm going to see what there is for breakfast.”
+
+“And that reminds me,” came from Mr. Jenks, “shall we move our camp,
+Bill, and take the tent with us to the cave?”
+
+“I hardly think so,” was the answer. “I think the best plan would be to
+conceal the tent somewhere around here, in case you might need it again.
+You can also store what food you have left.”
+
+“But, bless my appetite, we don't want to starve in that diamond cave!”
+ objected Mr. Damon.
+
+“I'll see that you don't,” declared Bill Renshaw. “I'll take you in
+there, unbeknownst to those fellows, and I'll provide you with plenty
+of food and water. You see the cave is so big that there are some parts
+they never visit.”
+
+“And we can stay in one of those parts, and eat?” asked Tom.
+
+“Sure,” answered Bill.
+
+“And watch the diamond makers at work?” asked Mr. Jenks.
+
+“That's it,” replied the former phantom.
+
+“Then the sooner we get started the better,” remarked Mr. Damon. Mr.
+Parker said nothing. He appeared to be thinking deeply, and was tapping
+at some rocks with his little hammer.
+
+The advice of Bill Renshaw was followed, and the tent, and what food
+remained, was concealed in the bushes, with rocks piled over to keep
+away prowling animals. Then they started for the secret cave.
+
+The man who played the part of a ghost picked up the framework and white
+cloth that had formed his disguise.
+
+“I'll still have to use this,” he explained, “for I don't want those
+fellows to know that I'm helping you. I'll continue to play the spirit
+of the mountain, but there won't be much need of it. I don't think any
+more people will come prospecting out here.”
+
+“Have you heard of the arrival of Farley Munson?” asked Tom, as he
+related the facts about the stowaway.
+
+“He hadn't arrived up to a day or so ago,” answered Bill. “I guess he's
+still traveling. Farley is one of the heads of the gang,” he added, “and
+a dangerous man.”
+
+As Bill led the way toward the cave, taking a route that the adventurers
+had never suspected led to it, he explained that the cavern was a large
+one, capable of holding an army.
+
+“But there's only a small part of it used by the diamond makers,” he
+added. “They work in a small recess, near the summit of the mountain.
+The little cave, where I'm going to take you, opens off from it by a
+long passage. And, except that you'll be pretty much in the dark, you'll
+be quite comfortable. There are tables, chairs, and some bunks in the
+place. I can get you some lights, and plenty of food.”
+
+“But, if you are seen taking away food, won't the others suspect
+something?” asked Tom.
+
+“I do pretty much as I please,” said Bill. “I go and come when I like.
+All I'm supposed to do is to watch my two sides of the mountain, play
+the ghost, and give warning when any one is coming. Sometimes I leave
+black and white messages, like the one I put on your tent. Those fellows
+fix 'em up for me. I've told 'em about you, though I didn't know who you
+were, and they think you have gone, for the two men on guard at the rear
+entrance so reported. Sometimes I stay out on the mountain for a couple
+of days at a time, when the weather's good, and don't go back to the
+cave. Those times I take food with me, and so if they see me making off
+with some supplies they'll think I'm going to camp out.”
+
+“It doesn't look as though we'd ever get into a cave near the top of the
+mountain, going this way,” said Tom, as they marched along. “We're going
+down, instead of up.”
+
+“That's the secret of this trail,” explained Bill. “We go down in a
+sort of valley, and then go up a pretty stiff place, and then we're on
+a direct trail to the entrance I told you about. It's a steep road to
+climb, but I guess we can manage it.”
+
+And a hard climb the adventurers did find it. The road was almost as bad
+as the one along the edge of the chasm, but they managed to negotiate
+it, and finally found themselves on a fairly good trail.
+
+“We'll soon be there,” Bill assured them. “After you get in the little
+cave, where I'm going to hide you, I'll have to leave you for a spell,
+until I get my ghost rigging fixed up again. But I'll see that you have
+plenty of food and drink.”
+
+A little later their guide came to a sudden halt, and peered around
+anxiously.
+
+“What's the matter?” asked Tom.
+
+“I was just looking to see if any of the men were about,” he answered.
+“But I guess not--it looks all right. The entrance is right here.”
+
+They were on a side of the mountain, near the summit. Below stretched a
+magnificent scene. A great valley lay at their feet, and they could look
+off to many distant peaks. The main trail to Leadville, and the one to
+the settlement of Indian Ridge, was in sight.
+
+Suddenly Tom, who had been using a small but powerful telescope, uttered
+an exclamation, and focussed the instrument on a speck that seemed
+moving along on the trail below.
+
+“A man--coming up the mountain,” cried Tom. “And--it can't be--yet it
+is--it's Farley Munson--the stowaway!” he cried. “He's coming here!”
+
+“Let me look!” begged Mr. Jenks, taking the glass from Tom. An instant
+later the diamond man exclaimed: “Yes, it's Munson!”
+
+“Then in here with you--quick!” cried Renshaw. “He can't see us yet, and
+we'll be out of sight in another minute.”
+
+The former spirit pulled aside some thick bushes, and pointed to a hole
+which was disclosed.
+
+“The entrance to the secret cave,” he announced. “Slip in all of you.”
+
+Tom, after another glance at the man toiling his way up the mountain,
+entered the cavern. He was followed by the others. Bill was the last to
+enter, and he replaced the bushes over the entrance.
+
+“At last!” exclaimed Mr. Jenks, as he gazed up at the roof of the
+dimly-lighted vault in which they found themselves.
+
+“Yes, we're in the diamond makers' secret cave,” added Tom. “Now to
+catch them at work!”
+
+“Come on,” advised Bill, in a low tone, “We're not safe yet,” and he
+produced a lantern from some hidden recess, lighted the wick, and led
+the way. As the others followed they were aware of a subdued noise in
+the great cavern.
+
+
+
+
+CHAPTER XX--MAKING THE DIAMONDS
+
+
+“What's that noise?” asked Tom, as their guide flashed the lantern to
+show them the way.
+
+“That's the men getting ready to make diamonds, I guess,” was the
+answer. “You see it takes quite a while to get the stuff ready. I don't
+know what they use--they never tell me any of their secrets.”
+
+“Oh, I know the ingredients well enough,” said Mr. Jenks, “but I
+don't know the secret of how they apply the terrific heat and pressure
+necessary to fuse the materials into diamonds.”
+
+“Well, you'll soon know,” declared Bill Renshaw. “Of course it isn't
+always successful. I've known 'em to try half a dozen times before they
+got any diamonds big enough to satisfy 'em. They gave me some of the
+small ones when I asked for my wages.
+
+“How did you come to get in with these men?” asked Tom, curious to
+understand how a person seemingly as honest as Renshaw appeared to be
+had cast his lot in with the men who had broken faith with Mr. Jenks.
+
+“Oh, I've lived around these parts all my life,” was the answer. “I knew
+of this cave before these diamond fellers came to it. In fact, I
+showed it to 'em. It was several years ago that a party of men who were
+prospecting around here came to me and asked if I knew of a small cave
+near the top of a high mountain, where lightning storms were frequent.
+I told them about Phantom Mountain, as it was called then, and also of
+this cave. If there's any place where they have worse lightning storms
+than here, I'd like to know it. They scare me, sometimes, like the night
+when that landslide happened, and I'm sort of used to 'em.
+
+“Well, I took these men to the cave, and they hired me as a sort of
+lookout. Then they began their work, and at first I didn't know what
+they were up to, but finally I caught on. Then Mr. Jenks came, and
+disappeared mysteriously, though then I didn't know that they had played
+a trick on him. I was outside most of the time, pretending I was the
+ghost. So that's how I came to get in with 'em, and I wish I was out.”
+
+“You soon will be, I think,” declared Mr. Jenks. “But won't our talking
+be heard by the men?”
+
+“No danger. There is a thick wall between this part of the cave, and the
+part where they live and work. I'll soon have you well hid, and then you
+wait until I come back.”
+
+“What about Munson?” asked Tom. “He is evidently on his way here to tell
+his confederates about us.”
+
+“He won't know what has happened to us,” said Mr. Jenks, “and he won't
+see anything of us. I guess we're safe enough.”
+
+Through the dark passage they followed Bill Renshaw until he came to a
+halt in a place that suddenly widened and broadened into a good-sized
+cave.
+
+“Here's your stopping place,” said the former ghost. “Now if you follow
+that passage, off to the left,” and he pointed to it, “you'll come
+to the larger part of the cave where the diamond makers are. But go
+cautiously, and don't make any noise. I won't be responsible for what
+happens.”
+
+“We'll take all the risk,” interrupted Tom.
+
+“All right. Now there's a couple of lanterns around here. I'll light
+them, and leave you for a while until I can get some grub. I'll be back
+as soon as I can.”
+
+He glided away, after lighting two lanterns, by the gleams of which
+the adventurers could see that they were in a vaulted cavern that had
+evidently been fitted up as a living apartment. The sides, roof and
+floor were of stone. It was clean, and the air was fresh. There were
+some chairs, a table, and several cots, with pieces of bagging for
+bedding, though it was warm in the place.
+
+“I guess we can stay here until we discover the secret,” spoke Tom.
+
+“Bless my watch! We can if we have something to eat,” came from Mr.
+Damon, with something like a sigh. “I'm hungry!”
+
+“And I want to make some observations,” said Mr. Parker. “From what I
+have seen of this mountain, I would not be surprised if this cave was
+to be suddenly destroyed by a landslide or a lightning bolt. I will make
+some further investigations.”
+
+“Well, if it's going to cause you to make such gloomy prophecies as
+that, I'd just as soon you wouldn't look any further,” spoke Tom, in
+a low voice. But Mr. Parker, taking one of the lanterns, set about
+examining the rock of which the cave consisted.
+
+In a short time Bill Renshaw returned with enough food to last for two
+days. He said he was going out on the mountain once more to act the part
+of a lookout, and would visit the adventurers again the next day.
+
+“In the meanwhile you can do just as you please,” he said. “Nobody is
+likely to disturb you here, and you can sneak up and take a look at the
+men in the other cave whenever you're ready. Only be careful--that's all
+I've got to say. They're desperate men.”
+
+It was not very pleasant, eating in the gloomy cavern, but they made the
+best of it. They cooked on a small oil-stove they found in the place,
+and after some hot coffee they felt much better.
+
+“Well,” remarked Tom, after a while, “shall we take a chance, and go
+look at the men at work?”
+
+“I think so,” answered Mr. Jenks. “The sooner we discover this mystery,
+the better. Then we can go back home.”
+
+“And recover my airship,” added Tom, who was a bit uneasy regarding the
+safety of the Red Cloud.
+
+“Then, bless my finger-rings! let's go and see if we can find the big
+cave your friend the ghost told us of,” suggested Mr. Damon.
+
+Cautiously they made their way along the passage Bill had pointed out.
+As they went forward the subdued noise became louder, and finally they
+could feel the vibration of machinery.
+
+“This is the place,” whispered Mr. Jenks. “That sound we hear is one of
+the mixing machines, for grinding the materials--carbon and the other
+substances--which go to make up the diamonds. I remember hearing that
+when I was in the cave before.”
+
+“Then we must be near the place,” observed Tom.
+
+“Yes, but I didn't have much chance to look around when I was here
+before. They wouldn't let me. I never even knew of the small cave Bill
+took us to.”
+
+“Well, if we're close to it, we'd better go cautiously, and not talk any
+more than we're obliged to,” suggested Mr. Parker, and they agreed that
+this was good advice.
+
+They walked on softly. Suddenly Tom, who was in the lead, saw a gleam of
+light.
+
+“We're here,” he whispered. “I'll put out our lantern, now,” which he
+did. Then, stealing forward he and the others beheld a curious sight.
+The tunnel they were in ended at a small hole which opened into a large
+cavern, and, fortunately, this opening was concealed from the view of
+those in the main place.
+
+“The diamond makers!” whispered Tom, hoarsely, pointing to several men
+grouped about a number of strange machines.
+
+“Yes--the very place where I was,” answered Mr. Jenks, “and there is the
+apparatus--the steel box--from which the diamonds are taken--now to see
+how they make them.”
+
+Fascinated, the adventurers looked into the cave. The men there were
+unaware of the presence of our friends, and were busily engaged. Some
+attended to the grinding machine, the roar and clatter of which made
+it possible for Tom and the others to talk and move about without being
+overheard. Into this machine certain ingredients were put, and they were
+then pulverized, and taken out in powdery form.
+
+The power to run the mixing machine was a gasoline motor, which
+chug-chugged away in one corner of the cave.
+
+As the powder was taken out, other men fashioned it into small balls,
+which were put on pan, and into a sort of oven, that was heated by a
+gasoline stove.
+
+“Is that how they make the diamonds?” asked Mr. Damon.
+
+“That is evidently the first step,” said Mr. Jenks. “Those balls of
+powdered chemicals are partly baked, and then they are put into the
+steel box. In some way terrific heat and pressure are applied, and the
+diamonds are made. But how the heat and pressure are obtained is what we
+have yet to learn.”
+
+He paused to watch the men at work. They were all busy, some attending
+to the machines, and others coming and going in and out of the cave. In
+one part a man was apparently getting ready a meal.
+
+Suddenly there rushed into the cave a man who seemed much excited.
+
+“Are you nearly ready with that stuff?” he cried. “There's a good storm
+gathering on the mountain!”
+
+“Yes, we'll be ready in half an hour,” answered one of the men at the
+mixing machine.
+
+“Good. It will be flashing lightning bolts then, and we can see what
+luck we have. The last batch was a failure.” The man hurried out again.
+Mr. Parker touched Tom and Mr. Jenks on their shoulders.
+
+“What is it?” asked Tom.
+
+“I know the secret of making the diamonds,” said the scientist.
+
+“What?” cried Mr. Jenks.
+
+“It is by the awful power of the lightning bolts!” whispered Mr. Parker.
+“Everything is explained now--the reason why they make diamonds in this
+lonely place, near the top of the mountain. They need a place where the
+lightning is powerful. I can understand it now--I suspected it before.
+They make diamonds by lightning!”
+
+“Are you sure?” cried Mr. Jenks.
+
+“Positive.”
+
+“I agree with you,” said Tom Swift. “I was just getting on that track
+myself, when I saw the electric wires running to the steel box. That
+explains the upright rod on the top of the mountain. The man says
+a storm is coming--very well; we'll stay here and watch them make
+diamonds!”
+
+As he spoke there came the mutter of thunder, and the mountain vibrated
+slightly. The men in the cave redoubled their activity. Tom and his
+friends felt that the secret process they had so long sought was about
+to be demonstrated before their eyes.
+
+
+
+CHAPTER XXI--FLASHING GEMS
+
+
+Eagerly the adventurers looked through the opening at the end of the
+passage into the larger cave. The men opened the small oven in which the
+balls of white chemicals and carbon mixed, had been baked, and a pile of
+things, that looked like irregularly-shaped marbles, were placed in the
+steel box.
+
+This box, which was about the size of a trunk, was of massive metal. It
+was placed in a recess in the solid rock, and all about were layers of
+asbestos and other substances that were nonconductors of heat.
+
+“That box becomes red hot,” exclaimed Mr. Jenks, in a whisper. “When
+things are in readiness, that lever is pulled and the diamonds are
+made. I pulled it once, but I did not then know the process involved. I
+supposed that the lightning had nothing to do with making the diamonds.”
+
+“It has--a most important part,” said Mr. Parker. The hidden adventurers
+could talk in perfect safety now, for the men in the large cave were too
+excited to pay much attention to them. The muttering of the thunder
+grew louder, and at times a particularly loud crash told that a bolt had
+struck somewhere in the vicinity of the cave.
+
+“But, bless my watch-charm!” exclaimed Mr. Damon, “I didn't know
+lightning made diamonds.”
+
+“It does not--always,” went on the scientist. “But great heat and
+pressure are necessary to create the gems. In nature this was probably
+obtained by prehistoric volcanic fires, and by the terrific pressure of
+immense rocks. It is possible to make diamonds in the laboratory of the
+chemist, but they are so minute as to be practically valueless.
+
+“However, these men seem to have hit upon a new plan. They utilize the
+terrific heat of lightning, and the pressure which is instantaneously
+obtained when the bolt strikes. I am anxious to see how it is done.
+Look, I think they are getting ready to make the gems.”
+
+Indeed there seemed to be an air of expectancy among the diamond makers.
+The mixing machine had now been stopped, and, as it was more quiet
+in the cave, our friends, in their hiding-place, had to speak in mere
+whispers. All the men were now gathered about the great steel box.
+
+This receptacle had been closed by a solid metal door, which was screwed
+and clamped tight. Then one of the men examined a number of heavily
+insulated electric wires that extended from the box off into the
+darkness where Tom and his companions could not discern them.
+
+“That's Folwell--the man I befriended, and who got me into this game,”
+ whispered Mr. Jenks. “He was also one of the first to turn against me. I
+think he's one of the leaders.”
+
+Folwell came back, after having gone into a dark part of the cave. He
+went over to an electrical switch on one of the stone walls.
+
+“It's almost time,” Tom heard him say to his confederates. “The storm is
+coming up rapidly.”
+
+“Will it be severe enough?” asked one of the helpers. “We had all our
+work for nothing last time. The flashes weren't heavy enough.”
+
+“These will be,” asserted Folwell. “The indicator shows nearly a million
+volts now, and it's increasing.”
+
+“A million volts!” exclaimed Tom. “I hope it doesn't strike anywhere
+around here.”
+
+“Oh, it will probably be harmlessly conducted down on the heavy wires,”
+ said Mr. Parker. “We are in no danger, at present, though ultimately I
+expect to see the whole mountain shattered by a lightning bolt.”
+
+“Cheerful prospect,” murmured Tom.
+
+There was a terrific crash outside. The rocky floor of the cave
+trembled.
+
+“Here she comes!” cried Folwell. “Get back, everybody! I'm going to
+throw over the switch now!”
+
+The men retreated well away from the steel box. Folwell threw over the
+lever--the same one Mr. Jenks remembered pulling. Then the man ran
+to the electric switch on the wall, and snapped that into place,
+establishing a connection.
+
+There was a moment's pause, as Folwell ran to join the others in their
+place of safety. Then from without there came a most nerve-racking and
+terrifying crash. It seemed as if the very mountain would be rent into
+fragments.
+
+Watching with eager eyes, the adventurers saw sparks flash from the
+steel box. Instantly it became red hot, and then glowed white and
+incandescent. It was almost at the melting point.
+
+Then came comparative quiet, as the echoes of the thunder died away amid
+the mountain peaks.
+
+“I guess that did the trick!” cried Folwell. “It was a terrific crash
+all right!”
+
+He and the others ran forward. The steel box was now a cherry red,
+for it was cooling. Folwell threw back the lever, and another man
+disconnected the switch. There was a period of waiting until the box was
+cool enough to open. Then the heavy door was swung back.
+
+With a long iron rod Folwell drew something from the retort. It was the
+tray which had held the white balls. But they were white no longer, for
+they had been turned into diamonds. From their hiding-place Tom and the
+others could see the flashing gems, for, in spite of the fact that the
+diamonds were uncut, some of them sparkled most brilliantly, due to the
+peculiar manner in which they were made.
+
+“We have the secret of the diamonds!” whispered Mr. Jenks. “There must
+be a quart of the gems there!”
+
+The men gathered about Folwell, uttering exclamations of delight. The
+diamonds were too hot to handle yet.
+
+“That's going some!” exclaimed the chief of the diamond makers. “We have
+a small fortune here.”
+
+The was a sudden commotion at one end of the cave. A man rushed in. At
+the sight of him Tom stared and uttered an exclamation.
+
+“Munson--the stowaway!” he whispered.
+
+“Hello!” cried Folwell, as he saw his confederate. “I thought you were
+East, keeping Jenks away from here.”
+
+“He got the best of me!” cried Munson, “he and that Tom Swift! I stowed
+away on their airship, but they found me out by a wireless message,
+and marooned me in the woods. I've been trying to get here ever since!
+Didn't you get my messages of warning?”
+
+“No--what warnings?” cried Folwell.
+
+“About Jenks, Tom Swift and the others. They're here--they must be on
+Phantom Mountain now. In fact, I shouldn't be surprised if they were in
+this cave. I traced them to their camp, but they're gone. They may be
+among us now--in some of the secret recesses!”
+
+For an instant Folwell stared at the bearer of these tidings. Then he
+cried out:
+
+“Scatter men, and find these fellows! We must get them before they
+discover our secret!”
+
+“It's too late--we know it!” exulted Tom Swift. Then he whispered to
+the others to hurry to the part of the cave where Bill Renshaw had first
+hidden them.
+
+
+
+
+CHAPTER XXII--PRISONERS
+
+
+“Do you think there is any danger of them finding us?” asked Mr. Damon,
+as he hurried along beside Tom.
+
+“I'm afraid so,” was the answer. “I've been worried ever since we saw
+Munson heading this way. But we couldn't do any differently.”
+
+“Perhaps Bill Renshaw may be able to conceal us,” suggested Mr. Jenks.
+“Very likely he knows that Munson is on hand. Perhaps we will be safe
+for a while. I want to make a few more observations as to how they
+manufacture the diamonds, and then, with what I already know, I'll have
+the secret.”
+
+“And I'd like to make some scientific tests of the sides and bottom
+rocks of the cave,” spoke Mr. Parker. “I think it will bear out my
+theory that the mountain will soon be destroyed.”
+
+“Well, you were right about Earthquake Island, and you may be right
+about this mountain,” said Tom, “but if it is going to be annihilated I
+hope we get far enough away from it.”
+
+“We can keep our presence here a secret for a few more days, I think
+that will be long enough,” proceeded Mr. Jenks. “Then we will leave.”
+
+“And, in the meanwhile, they'll be searching for us,” objected Mr.
+Damon. “I wish that ghost-chap would come back and tell us what to do.
+Bless my liver-pin, but we are going to be in considerable danger, I'm
+afraid! Those men may capture us, and decide to make diamond dust from
+us.”
+
+“Come on--hurry to the little cave,” urged Tom. “Then we'll get ready to
+defend ourselves.”
+
+“The main cave is a large one,” said Mr. Jenks, “and there are many
+hiding places in it. In fact, it is so large that it will take those
+fellows several days to complete a circuit of it. By that time Bill
+Renshaw may come back, and take us to some place in which they have
+already searched for us. Then we'll be comparatively safe.”
+
+This thought was some consolation to them, as they made their way
+through the dark passage, dimly illuminated by the lantern they had
+rekindled, to the place where Bill had hidden them. They found things
+as they had left them, and proceeded to get a meal, though Tom said it
+would be best not to cook anything, or even to make coffee, for fear the
+odors would enable the searchers to trail them.
+
+So they ate cold food, glad to get that. Silently they sat about the
+dimly-lighted cavern, and discussed the situation. True they might even
+now retreat, going out of the entrance Bill had showed them, and so
+escape. But Mr. Jenks felt that his mission was not completed yet, and
+they all agreed to stay with him.
+
+“For there are several points about making diamonds that are not
+quite clear to me,” he said. “I need to know how that steel box is
+constructed, how the electrical switches are arranged, what kind of
+lightning rods they use, and how they regulate the pressure. The other
+things, and how to mix the ingredients, I already know.”
+
+“Then we'll do our best to help you,” promised Tom. “But now I think we
+had better see what sort of a defense we can put up. We have our guns
+and revolvers, and with these chairs and tables we can build a sort of
+barricade behind which we can take refuge if those fellows do discover
+our hiding place.”
+
+This was conceded to be a good idea, and soon a rude sort of fort was
+made, behind which the adventurers could take their stand and fight, if
+necessary, though they hoped this would not come to pass.
+
+They remained quietly in the cave the remainder of that day, and, when
+it was night, as they could tell by their timepieces--there was no
+daylight--they divided the hours into watches, taking turns standing
+guard.
+
+Morning, at least in point of time, came without any disturbance, and
+they made a cold breakfast. They hoped that Bill Renshaw would come, but
+he did not appear.
+
+After sitting in the dark cave until afternoon, Tom said:
+
+“I think we might as well go and take another observation of the big
+cave. We can tell what the men are doing, then, for they don't seem to
+have been near us. Maybe they have given up the search for us, and we
+can see them at work, and Mr. Jenks can gain what further knowledge he
+needs.”
+
+“That will be a good plan,” agreed the diamond man. “It's maddening to
+sit here, doing nothing.”
+
+“And it will be comparatively safe to go from here to our former post of
+observation,” added Tom, “for there doesn't seem to be any opening along
+the tunnel, into the larger cave, except the place where we were.”
+
+Accordingly they started off. Cautiously they looked through the opening
+into the apartment where they had seen the diamonds made.
+
+“There's not a soul here!” exclaimed Tom, in a whisper. The others
+looked. The place was deserted--the machinery silent. Mr. Jenks peered
+in for a moment, and then exclaimed:
+
+“I'm going in! Now's my chance to find out all that I wish to know! It
+may never come again, and then we can soon leave Phantom Mountain!”
+
+It was a daring plan, but it seemed to be the best one to follow. They
+were all tired of inactivity. Mr. Jenks managed to get through the
+opening, and dropped into the big cave. The others followed. Mr. Jenks
+hurried over to the steel box, and began an examination of it. Tom Swift
+was looking at the electrical switch. He saw how it was constructed. Mr.
+Damon and Mr. Parker were peering interestedly about.
+
+Suddenly the sound of voices was heard, and the echo of footsteps. Mr.
+Jenks started.
+
+“They're coming back!” he whispered hoarsely. “Run!”
+
+They all turned and sped toward their hiding place. But they were too
+late. An instant later Folwell, Munson and the other diamond makers
+confronted them. Our friends made a bold rush, but were caught before
+they could go ten feet.
+
+“We have them!” cried Munson. “They walked right into our hands!”
+
+It was true. Tom Swift and the others were the prisoners of the diamond
+makers.
+
+
+
+CHAPTER XXIII--BROKEN BONDS
+
+
+“Well,” remarked Tom Swift, in mournful tones, “this looks as if we were
+up against it; doesn't it?”
+
+“Bless my umbrella, it certainly does,” agreed Mr. Damon.
+
+“And it's all my fault,” said Mr. Jenks. “I shouldn't have gone into the
+big cave. I might have known those men would come back any time.”
+
+The above conversation took place as our friends lay securely bound in
+a small cave, or recess, opening from the larger cavern, where, about
+an hour before, they had been captured and made prisoners by the diamond
+makers. Despite their struggles they had been overpowered and bound,
+being carried to the cave, where they were laid in a row on some old
+bags.
+
+“It certainly is a most unpleasant situation, to say the least,”
+ observed Mr. Parker.
+
+“And all my fault,” repeated Mr. Jenks.
+
+“Oh, no it isn't,” declared Tom Swift, quickly. “We were just as ready
+to follow you into that cave as you were to go. No one could tell that
+the men would return so soon. It's nobody's fault. It's just our bad
+luck.”
+
+From where he lay, tied hand and foot, the young inventor could look
+out into the cave where he and the others had been caught. The diamond
+makers were busily engaged, apparently in getting ready to manufacture
+another batch of the precious stones. They paid little attention to
+their captives, save to warn them, when they had first been taken into
+the little cave, that it was useless to try to escape.
+
+“They needn't have told us that,” observed Tom, as he and the others
+were talking over their situation in low voices. “I don't believe any
+one could loosen these ropes.”
+
+“They certainly are pretty tight,” agreed Mr. Damon. “I've been tugging
+and straining at mine for the last half hour, and all I've succeeded in
+doing is to make the cords cut into my flesh.”
+
+“Better give it up,” advised Mr. Jenks.
+
+“We'll just have to wait.”
+
+“For what?” the scientist wanted to know.
+
+“To see what they'll do with us. They can't keep us here forever.
+They'll have to let us go some time.” Following their capture, Folwell
+and Munson, the latter the stowaway of the airship, had been in earnest
+conversation regarding our friends, but what conclusion they had reached
+the adventurers could only guess.
+
+“And we didn't have time to examine the diamond-making machinery close
+enough so that we could duplicate it if necessary,” complained Tom, a
+little later.
+
+“No,” agreed Mr. Jenks. “There are certain things about it that are not
+clear to me. Well, I don't believe I'll have another chance to inspect
+it. They'll take good care of that, though they seem to be getting ready
+to make more diamonds.”
+
+“Perhaps they're going to manufacture a big batch, and then leave this
+place,” suggested Mr. Damon. “They will probably go to some other secret
+cave, and leave us here.”
+
+“I hope they untie us before they leave, and give us something to eat,”
+ remarked the young inventor.
+
+For two hours longer the captives lay there, in most uncomfortable
+positions. Then Folwell and Munson, leaving the group of diamond makers
+who were grouped about the machinery, approached the captives.
+
+“Well,” remarked Munson, “we got ahead of you after all; didn't we. You
+thought you had our secret, but it will be a long while before you ever
+make diamonds.”
+
+“What are you going to do with us?” asked Tom.
+
+“Never mind. You came where you had no right to, and you must take the
+consequences.”
+
+“We did have a right to come here!” exclaimed Mr. Jenks. “I am entitled
+to know how the diamonds are made. I paid for the information, and you
+tricked me. If ever it's possible I'll have the whole gang arrested for
+swindling.”
+
+“You'll never get the chance!” declared Folwell. “You were given some
+diamonds for the money you invested, and that makes us square.”
+
+“No, it doesn't!” declared Mr. Jenks. “I invested the money to learn how
+to make diamonds, and you know it! You tricked me, and I had a right
+to try to discover your secret! I nearly have it, too, and I'll get it
+completely before I'm done with you!”
+
+“No, you won't!” boasted Folwell. “But we didn't come here to tell you
+that. We came to give you something to eat. We're not savages and
+we'll treat you as well as we can in spite of the fact that you are
+trespassers. We're going to give you some grub, but I warn you that any
+attempt to escape will mean that some of you will get hurt.”
+
+He signalled to some of his confederates. These men unbound the
+captives' arms, and stood over them while they ate some coarse food that
+was brought into the small cave. They were given coffee to drink, and
+then, when the simple meal was over, they were securely bound again,
+and left to themselves, while the diamond makers went back to their
+machinery.
+
+It was evident that they were going to attempt a big operation, for an
+unusually large quantity of the white stuff was prepared. The prisoners
+watched them idly. They could see some but not all of the operations. In
+this way several hours passed.
+
+Gloom possessed the hearts of Tom and his friends. Not only had their
+expedition been almost a failure so far, but the young inventor was
+worried lest the gang might discover and wreck his airship. This would
+prove a serious loss. Lying there in the semi-darkness the lad imagined
+all sorts of unpleasant happenings.
+
+At times he dozed off, as did the others. They had become somewhat used
+to the pain caused by the bonds, for their nerves were numb from the
+strain and pressure.
+
+Once, as he was lightly sleeping, Tom was awakened by hearing loud
+voices in the main cave. He looked out, rolling over slightly to get a
+better view. He saw the man who, once before had run in to give news of
+an approaching electrical storm.
+
+“Are you fellows all ready?” asked this same man again.
+
+“Yes. Is there another storm coming?”
+
+“Yes, and it's going to be a corker!” was the reply. “It's one of the
+worst I've ever seen. It's sweeping right up the valley. It'll be here
+in an hour.”
+
+“That's good. We need a big flash to make all the material we have
+prepared into diamonds. It's the biggest batch we ever tried. I hope it
+succeeds, for we're going to leave--” The rest was in so low a tone that
+Tom could not catch it.
+
+The storm messenger departed. Folwell and Munson busied themselves about
+the machinery. Tom dozed off again, dimly wondering what had become of
+Bill Renshaw, and whether the former ghost knew of their plight. The
+others were asleep, as the young inventor saw by the dim light of a
+lantern in the cave. Then, he too, shut his eyes.
+
+Tom was suddenly awakened by feeling some one's hands moving about his
+clothing. At first he thought it was one of the diamond-making gang, who
+had sneaked in to rob him. “Here! What are you up to?” exclaimed Tom.
+
+“Quiet!” cautioned a voice. “Are you all here?”
+
+“All of us--yes. But who are you?”
+
+“Easy--keep quiet, Tom Swift! I'm Bill Renshaw! I've been searching all
+over for you, since I got back to your cave and found it empty. Now I'm
+going to free you. I got in here by a secret entrance. Wait, I'll cut
+your ropes.” There was a slight sound, and an instant later Tom was
+freed from his bonds.
+
+
+
+
+CHAPTER XXIV--IN GREAT PERIL
+
+
+The young inventor could scarcely believe the good luck that had so
+unexpectedly come to him and his companions. No sooner was Tom able to
+move freely about than Bill Renshaw performed the same service for Mr.
+Jenks and the others, cautioning them to be quiet as he awakened them,
+and cut the ropes.
+
+“Bless my circulation!” exclaimed Mr. Damon, in a hoarse whisper. “How
+did you ever get here. I'd given ourselves up for lost.”
+
+“Oh, I came in off the mountain, as there's a big storm due,” explained
+the man. “There was no need of me playing the haunt in daytime, anyhow.
+I went to the cave, found you and your things gone, and I surmised that
+you might have walked into some trap.”
+
+“We did,” admitted Mr. Jenks, grimly.
+
+“Well, I hunted around until I found you,” went on Bill. “This mountain
+is honeycombed with caves, all opening from the large one, I know them
+better than these fellows do, so I could explore freely, and keep out of
+their sight. They didn't know that there was a second entrance to this
+place, but I did, and I made for it, when I couldn't find you in some of
+the other caves where I looked. And, sure enough, here you were.”
+
+“Well, we can't thank you enough,” said Mr. Parker. “But you say there
+is a big storm coming?”
+
+“One of the biggest that's been around these parts in some time,”
+ replied Bill.
+
+“Then perhaps the mountain will be destroyed,” went on the scientist, as
+calmly as if he had remarked that it might rain.
+
+“I hope nothing like that happens until we get away,” spoke Mr. Damon,
+fervently.
+
+“What had we better do?” inquired Tom.
+
+“Get away, unless you want to discover some more of their secrets,”
+ advised Bill. “Those fellows are planning something, but I can't find
+out what it is. They are suspicious of me, I think. But they are up to
+something, and I believe, it would be best for you to leave while you
+have the chance. It may not be healthy to stay. That's why I did my best
+to untie you.”
+
+“We appreciate what you have done,” declared Mr. Jenks, “but I want my
+rights. I must learn a few more facts about how to make diamonds from
+lightning flashes, and then I will have the same secret they cheated me
+out of. I think if we wait a while we may be able to see the parts of
+the process that are not quite clear to us. What do you say, Tom Swift?”
+
+“Well, I would like to learn the secret,” replied the lad, “and if Bill
+thinks it's safe to stay here a while longer--”
+
+“Oh, I guess it will be safe enough,” was the reply. “Those fellows
+won't bother about you now that they are about to make some more
+diamonds. Besides, they think you're all tied up. Yes, you can stay here
+and watch, I reckon. I've got a couple of guns, and--”
+
+“Then we'll stay,” decided Tom. “We can put up a better fight now.”
+
+Silently, in their prison, but which they could now leave whenever they
+pleased, the adventurers watched the diamond makers once more. The same
+process they had witnessed before was gone through with. The white balls
+were put inside the steel box and sealed up. Then they waited for the
+storm to reach its height.
+
+That this would not be long was evidenced by the mutterings of thunder
+which every moment grew louder. The outburst of electrical fury was
+likely to take place momentarily, and that it would be unusually severe
+was shown by the precautions taken by the diamond makers. They attached
+a number of extra wires, and brought out some insulated, hard rubber
+platforms, on which they themselves stood. Tom and Mr. Jenks were much
+interested in watching this detail of the work, and sought to learn how
+each part of the process was done.
+
+“I almost think we can make diamonds, Tom, when we get back to
+civilization,” whispered Mr. Jenks.
+
+“I hope we can,” answered Tom, “and we can't get back any too soon to
+suit me. I want to be in my airship again.”
+
+“I don't blame you. But look, they are getting ready to adjust the
+switch.”
+
+The adventurers ceased their whispered talk, and eagerly watched the
+diamond makers. Folwell and Munson were hurrying to and fro in the big
+cave, attending to the adjustments of the machinery.
+
+“On your insulated plates--all of you,” Folwell gave the order. “This
+is going to be a terrific storm. The gage shows twice the power we have
+ever used, and it's creeping up every minute! We'll have more diamonds
+than ever had before!”
+
+“Yes, if the mountain isn't destroyed,” added Mr. Parker, in a low
+voice. “I predict that it will be split from top to bottom!”
+
+“Comforting,” thought Tom, grimly.
+
+“I guess we're all ready,” said Folwell, in a low tone to Munson. “We'd
+better get insulated ourselves. I'm going to throw the switch.”
+
+He did so. A moment later the man who had before given warning of the
+storm came dashing in. He was very much excited.
+
+“It's awful!” he cried. “The lightning is striking all over! Big rocks
+are being split like logs of wood!”
+
+“Well, it can't do any damage in here,” said Munson. “We are well
+protected. Get on one of the plates,” and he motioned to one of the
+hard-rubber platforms that was not occupied. The roar and rumble of the
+storm outside had given place to short terrific crashes. In their small
+cave the adventurers could feel the solid ground shake.
+
+A bluish light began dancing about the electrical wires. There was a
+smell of sulphur in the air. Crash after crash resounded outside. A
+flash of flame lit up the whole interior of the cave. It came from the
+copper switch.
+
+“Something's wrong with the insulation!” cried Munson.
+
+“Don't go near it!” yelled Folwell. “If you value your life, stand
+still!”
+
+Hardly had he spoken than inside the cavern there sounded a report like
+that of a small cannon. A big ball of fire danced about the middle of
+the cave and then leaped on top of the steel box.
+
+“This is a fearful storm,” cried Munson.
+
+The adventurers in the cave did not know what to say or do. They were in
+deadly peril.
+
+Suddenly there came a crash louder than any that had preceded it. The
+whole side of the cave where the switches were was a mass of bluish
+flame. Then came a ripping, tearing sound, and a tangle of wires and
+copper connections were thrown to the floor. At the same time the steel
+box, containing the materials from which diamonds were made, turned
+blue, and flames shot from it.
+
+“It's all up with us!” cried Munson. “Run for it, everybody! The wires
+are down, and this place will be an electric furnace in another minute!”
+
+He leaped toward the exit from the cave.
+
+“What about those fellows?” asked Folwell, indicating the place where
+Tom and the others had been tied.
+
+“They'll have to do the best they can! It's every man for himself, now!”
+ yelled Munson. There was a wild scramble from the cavern.
+
+“Come on!” cried Tom. “We must escape! It's our only chance!”
+
+He leaped into the big cave, followed by the others. Already long
+tongues of electrical fire were shooting out from the walls and roof as
+Tom Swift and his companions, evading them as best they could, sought
+safety in flight.
+
+
+
+CHAPTER XXV--THE MOUNTAIN SHATTERED--CONCLUSION
+
+
+“Can't we get some of the diamonds?” cried Mr. Damon, as he raced along
+behind Tom. “Now's our chance. Those fellows have all gone!” The odd man
+made a grab for something as he ran.
+
+“It's as much as our lives are worth,” declared the young inventor. “We
+dare not stop! Come on!”
+
+“I'd like to investigate some of the machinery,” spoke Mr. Jenks, “but I
+wouldn't stop, even for that.”
+
+“The storm is too dangerous,” called Bill Renshaw. “I can show you a
+shorter way out than the one those fellows have taken. Follow me.”
+
+“No way can be too short,” said Mr. Parker, solemnly. “This mountain
+will go to pieces shortly, I think!”
+
+Tom shuddered. He remembered how narrow had been their escape when
+Earthquake Island sank into the sea. And that some terrific upheaval was
+now imminent might be judged from the awful reports that sounded more
+plainly as the adventurers raced toward the opening of the cave. It was
+like the bombardment of some doomed city.
+
+Mr. Jenks and Tom cast one longing look behind at the complicated and
+expensive machinery that had been installed in the cave by the diamond
+makers. They had abandoned it, and in it lay the secret of making
+precious gems. But there was no time to stop now, and investigate.
+
+“This way,” urged Bill Renshaw. “We'll soon be out.”
+
+“But won't it be dangerous to go outside?” asked Mr. Damon. “Shan't we
+be struck by lightning? There is some protection in here.”
+
+“None at all,” said Mr. Parker, quickly. “This mountain is a natural
+lightning rod. To stay here in this cave will be sure death when the
+storm gets directly over it. And that will be very soon. We must get
+on insulated ground. Is there any part of this mountain that does not
+contain iron ore?” the scientist asked of the former spirit.
+
+“Yes; the way out by which we are going lands on a dirt hill.”
+
+“That's good; then we may be saved.”
+
+On they ran. They had no lanterns, but the blue light of the
+electricity, as it leaped from point to point inside the cave, where
+there were outcroppings of iron ore, made the place bright enough to
+see.
+
+“Here we are!” cried Bill Renshaw at length. “Here's the way out!”
+
+Making a sudden turn in the winding passage he showed the adventurers
+a small opening in the side of the crag. In an instant they had passed
+through, and found themselves in daylight once more. The sudden glare
+almost blinded them, for, though the sky was overcast by clouds, from
+which jagged tongues of lightning played, the outside was much lighter
+than the dark cave.
+
+“I should say it was a storm!” cried Tom Swift. “See, it is striking
+every minute, and all around us!”
+
+In fact, lightning bolts were falling on every side of the adventurers.
+Every time the balls of fire struck, they burst open great stones,
+or seared a livid scar on the face of some cliff. As for Tom and the
+others, they stood on a dry dirt hill, in which, fortunately, there was
+no iron ore. To this fact they undoubtedly owed their lives, though
+had there been rain, to moisten the ground and make the earth a good
+conductor of electricity, they probably would have been badly shocked.
+But the electrical outburst was not accompanied by rain.
+
+Tom looked up. He saw a compact mass of cloud moving toward the summit
+of the mountain on the slope of which they stood. From this cloud there
+played shafts of reddish-green fire.
+
+“Look!” called the young inventor to Mr. Parker. The instant the latter
+saw the cloud, he cried:
+
+“We must get away from here by all means! That is the center of the
+storm. As soon as it gets over the mountain, where that lightning rod
+is, all the electrical fluid will be discharged in one bolt at the
+mountain, and it will be destroyed! We must run, but keep on the dirt
+places! Run for your lives!”
+
+They needed no second warning. Turning, they fled down the steep side of
+the mountain, slipping and stumbling, but taking care not to step on any
+iron ore. Behind them flashed the lightning bolts.
+
+Suddenly there was a most awful crash. It seemed as if the end of the
+world had come, and the ear drums of Tom and his companion almost burst
+with the fearful report. The concussion knocked them down, and they lay
+stunned for a moment.
+
+Following the terrible report there was a low, rumbling sound. Hardly
+knowing whether he was dead or alive, Tom opened his eyes and looked
+about him. What he saw caused him to cry out in terror.
+
+The whole mountain seemed bathed in fire. Great blue, red and green
+flashes played around it. Then the towering cliff seemed to melt and
+crumble up, and the great peak, the top of it containing the diamond
+makers' cave, from which they had fled but a few minutes before, the
+entire summit was toppled over into the valley on the other side, and in
+the direction opposite to that where the adventurers stood.
+
+Then came a profound silence, and the lightning ceased. The storm was
+over, and only the rattle of stones and boulders, as they came to rest
+in the valley below, reached the ears of our friends.
+
+“Phantom Mountain has been destroyed, just as I said it would be,” spoke
+Mr. Parker, solemnly. Once more he had prophesied correctly.
+
+For a few minutes the adventurers hardly knew what to say. They arose
+awkwardly from the ground where the shock had tossed them. Then Tom
+remarked, as calmly as possible:
+
+“Well, it's all over. I guess we may as well get back to our airship.”
+
+“What became of Munson and the others?” asked Mr. Damon.
+
+Mr. Jenks pointed to the trail, far below. The figures of some men,
+running madly, could be seen.
+
+“There they go,” he said; “I fancy we have seen the last of them.” And
+they had, for some time at least.
+
+There was little use lingering any longer on Phantom Mountain--indeed
+little of it was left on which to remain. Looking back toward the place
+where the cave had been, Tom and the others started forward again.
+The diamond-making machinery had all been destroyed. So, also, had the
+finished diamonds stored in the cavern and the large supply which had
+probably been made by the last terrific crash. No one would ever have
+them now. Tom and Mr. Jenks felt a sense of disappointment, but they
+were glad to have escaped with their lives. They sought their former
+camp, but the tent and all their food was buried under tons of earth and
+rocks.
+
+Three days later, after rather severe hardships, they were near the
+place where they had left the Red Cloud. They had suffered cold and
+hunger, for they had no food supplies, and, had it not been that Bill
+Renshaw knew the haunts of some game, of which they managed to snare
+some, they would have fared badly, for they had left their guns in the
+cave.
+
+“Well, there are the trees behind which I hope my airship is hidden,”
+ announced Tom, as they came to the spot. “Good old Red Cloud! Maybe we
+won't do some eating when we get aboard, eh?”
+
+“Bless my appetite! but we certainly will!” cried Mr. Damon.
+
+“There's somebody walking around the place,” spoke Mr. Jenks.
+
+“I hope it's no one who has damaged the ship,” came from Tom,
+apprehensively. He broke into a run, and soon confronted an aged miner,
+who seemed to have established a rude sort of camp near the airship.
+
+“Is anything the matter?” asked Tom, breathlessly. “Is my airship all
+right?”
+
+“I guess she's all right, stranger,” was the reply. “I don't know much
+about these contraptions, but I haven't touched her. I knowed she was an
+airship, for I've seen pictures of 'em, and I've been waiting until the
+owner came along.”
+
+“Why?” asked Tom, wonderingly.
+
+“Because I've got a proposition to make to you,” went on the miner, who
+said his name was Abe Abercrombie. “I've been a miner for a good many
+years, and I'm just back from Alaska, prospecting around here. I haven't
+had any luck, but I know of a gold mine in Alaska that will make us all
+rich. Only it needs an airship to get to it, and I've been figuring how
+to hire one. Then I comes along, and I sees this big one, and I makes up
+my mind to stay here until the owners come back. That's what I've done.
+Now, if I prove that I'm telling the truth, will you go to Alaska--to
+the valley of gold with me?”
+
+“I don't know,” answered Tom, to whom the proposition was rather sudden.
+“We've just had some pretty startling adventures, and we're almost
+starved. Wait until we get something to eat, and we'll talk. Come aboard
+the Red Cloud,” and the lad led the way to his craft which was in as
+good condition as when he left it to go to the diamond cave. Later he
+listened to the miner's story.
+
+Tom Swift did go to the valley of gold in Alaska, and what happened to
+him and his companions there will be told of in the next volume of this
+series, to be called “Tom Swift in the Caves of Ice; or, the Wreck of
+the Airship.”
+
+It did not take our friends long, after they had eaten a hearty meal,
+to generate some fresh gas, and start the Red Cloud on her homeward way.
+Tom wanted to take Bill Renshaw with him, but the old man said he would
+rather remain among the mountains where he had been born. So, after
+paying him well for his services, they said good-by to him. Abercrombie,
+the miner, also remained behind, but promised to call and see Tom in a
+few months.
+
+“Well, we didn't make any money out of this trip,” observed Mr. Jenks,
+rather dubiously, as they were nearing Shopton, after an uneventful
+trip. “I guess I owe you considerable, Tom Swift. I promised to get you
+a lot of diamonds, but all I have are those I had from my first visit to
+the cave.”
+
+“Oh, that's all right,” spoke Tom, easily. “The experience was worth all
+the trip cost.”
+
+“Speaking of diamonds, look here!” exclaimed Mr. Damon, suddenly, and he
+pulled out a double handful.
+
+“Where did you get them?” cried the others in astonishment.
+
+“I grabbed them up, as we ran from the cave,” said the eccentric man;
+“but, bless my gaiters! I forgot all about them until you spoke. We'll
+share them.”
+
+These diamonds, some of which were large, proved very valuable, though
+the total sum was far below what Mr. Jenks hoped to make when he started
+on the remarkable trip. Tom gave Mary Nestor a very fine stone, and it
+was set in a ring, instead of a pin, this time.
+
+On their arrival in Shopton, where Mr. Swift, the housekeeper, Mr.
+Jackson and Eradicate Sampson were much alarmed for Tom's safety, an
+attempt was made to manufacture diamonds, using a powerful electric
+current instead of lightning. But it was not a success, and so Mr. Jenks
+concluded to give up his search for the secret which was lost on Phantom
+Mountain.
+
+And now we will take leave of Tom Swift, to meet him again soon in other
+adventures he is destined to have in the caves of ice and the valley of
+gold.

+ <h2>
+ CHAPTER I&mdash;A SUSPICIOUS JEWELER
+ </h2>
+ <p>
+ &ldquo;Well, Tom Swift, I don't believe you will make any mistake if you buy
+ that diamond,&rdquo; said the jeweler to a young man who was inspecting a tray
+ of pins, set with the sparkling stones. &ldquo;It is of the first water, and
+ without a flaw.&rdquo;
+ </p>
+ <p>
+ &ldquo;It certainly seems so, Mr. Track. I don't know much about diamonds, and
+ I'm depending on you. But this one looks to be all right.&rdquo;
+ </p>
+ <p>
+ &ldquo;Is it for yourself, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Er&mdash;no&mdash;that is, not exactly,&rdquo; and Tom Swift, the young
+ inventor of airships and submarines, blushed slightly.
+ </p>
+ <p>
+ &ldquo;Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I think she
+ would like a pin of this sort. True, it's rather expensive, but&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;No, it isn't for Mrs. Baggert, Mr. Track,&rdquo; and Tom seemed a bit
+ embarrassed.
+ </p>
+ <p>
+ &ldquo;No? Well, then, Tom&mdash;of course it's none of my affair, except to
+ sell you a good stone, But if this brooch is for a young lady, I can't
+ recommend anything nicer. Do you think you will take this; or do you
+ prefer to look at some others?&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I think this will do, Mr. Track. I guess I'll take&mdash;&rdquo;
+ </p>
+ <p>
+ Tom's words were interrupted by a sudden action on the part of the
+ jeweler. Mr. Track ran from behind the showcase and hastened toward the
+ front door.
+ </p>
+ <p>
+ &ldquo;Did you see him, Tom?&rdquo; he cried. &ldquo;I wonder which way he went?&rdquo;
+ </p>
+ <p>
+ &ldquo;Who?&rdquo; asked the lad, following the shopkeeper.
+ </p>
+ <p>
+ &ldquo;That man. He's been walking up and down in front of my place for the last
+ ten minutes&mdash;ever since you've been in here, in fact, and I don't
+ like his looks.&rdquo;
+ </p>
+ <p>
+ &ldquo;What did he do?&rdquo;
+ </p>
+ <p>
+ &ldquo;Nothing much, except to stare in here as if he was sizing my place up.&rdquo;
+ </p>
+ <p>
+ &ldquo;Sizing it up?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes. Getting the lay of the land, so he or some confederate could commit
+ a robbery, maybe.&rdquo;
+ </p>
+ <p>
+ &ldquo;A robbery? Do you think that man was a thief?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know that he was, Tom, and yet a jeweler has to be always on the
+ watch, and that isn't a joke, either, Tom Swift. Swindlers and thieves are
+ always on the alert for a chance to rob a jewelry store, and they work
+ many games.&rdquo;
+ </p>
+ <p>
+ &ldquo;I didn't notice any particular man looking in here,&rdquo; said Tom, who still
+ held the diamond brooch in his hand.
+ </p>
+ <p>
+ &ldquo;Well I did,&rdquo; went on the jeweler. &ldquo;I happened to glance out of the window
+ when you were looking at the pins, and I saw his eyes staring in here in a
+ suspicious manner. He may have a confederate with him, and, when you're
+ gone, one may come in, and pretend to want to look at some diamonds. Then,
+ when I'm showing him some, the other man will enter, engage my attention,
+ and the first man will slip out with a diamond ring or pin. It's often
+ done.&rdquo;
+ </p>
+ <p>
+ &ldquo;You seem to have it all worked out, Mr. Track,&rdquo; observed the lad, with a
+ smile. &ldquo;How do you know but what I'm in with a gang of thieves, and that
+ I'm only pretending to want to buy a diamond pin?&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I guess I haven't known you, Tom Swift, ever since you were big
+ enough to toddle, not to be sure about what you're up to. But I certainly
+ didn't like the looks of that man. However, let's forget about him. He
+ seems to have gone down the street, and, after all, perhaps I was
+ mistaken. Just wait until I show you a few more styles before you decide.
+ The young lady may like one of these,&rdquo; and the jeweler went to another
+ showcase and took out some more trays of brooches.
+ </p>
+ <p>
+ &ldquo;What makes you think she's a young lady, Mr. Track?&rdquo; asked the lad.
+ </p>
+ <p>
+ &ldquo;Oh, it's easy guessing, Tom. We jewelers are good readers of character. I
+ can size up a young fellow coming in here to buy an engagement or a
+ wedding ring, as soon as he enters the door. I suppose you'll soon be in
+ the market for one of those, Tom, if all the reports I hear about you are
+ true&mdash;you and a certain Mary Nestor.&rdquo;
+ </p>
+ <p>
+ &ldquo;I&mdash;er&mdash;I think I don't care for any of these pins,&rdquo; spoke Tom,
+ quickly, with a blush. &ldquo;I like the first lot best. I think I'll take the
+ one I had in my hand when that man alarmed you. Ha! That's odd! What did I
+ do with it?&rdquo;
+ </p>
+ <p>
+ Tom looked about on the showcase, and glanced down on the floor. He had
+ mislaid the brooch, but the jeweler, with a laugh, lifted it out of a tray
+ a moment later.
+ </p>
+ <p>
+ &ldquo;I saw you lay it down,&rdquo; he said. &ldquo;We jewelers have to be on the watch.
+ Here it is. I'll just put it in a box, and&mdash;&rdquo;
+ </p>
+ <p>
+ With an exclamation, Mr. Track gave a hasty glance toward his big show
+ window. Tom looked up, and saw a man's face peering in. At the sight of
+ it, he, too, uttered a cry of surprise.
+ </p>
+ <p>
+ The next instant the man outside knocked on the glass, apparently with a
+ piece of metal, making a sharp sound. As soon as he heard it, the jeweler
+ once more sprang from behind the showcase, and leaped for the door crying:
+ </p>
+ <p>
+ &ldquo;There's the thief! He's trying to cut a hole through my show window and
+ reach in and get something! It's an old trick. I'll get the police! Tom,
+ you stay here on guard!&rdquo; and before the lad could utter a protest, the
+ jeweler had opened the door, and was speeding down the street in the
+ gathering darkness.
+ </p>
+ <p>
+ Tom stared about him in some bewilderment. He was left alone in charge of
+ a very valuable stock of jewelry, the owner of which was racing after a
+ supposed thief, crying:
+ </p>
+ <p>
+ &ldquo;Police! Help! Thieves! Stop him, somebody!&rdquo;
+ </p>
+ <p>
+ &ldquo;This is a queer go,&rdquo; mused Tom. &ldquo;I wonder who that man was? He looked
+ like somebody I know, and yet I can't seem to place his face. I wonder if
+ he was trying to rob the place? Maybe there's another one&mdash;a
+ confederate&mdash;around here.&rdquo;
+ </p>
+ <p>
+ This thought rather alarmed Tom, so he went to the door, and looked up and
+ down the street. He could see no suspicious characters, but in the
+ direction in which the jeweler was running there was a little throng of
+ people, following Mr. Track after the man who had knocked on the window.
+ </p>
+ <p>
+ &ldquo;I wish I was there, instead of here,&rdquo; mused the lad. &ldquo;Still I can't
+ leave, or a thief might come in. Perhaps that was the game, and one of the
+ gang is hanging around, hoping the store will be deserted, so he can enter
+ and take what he likes.&rdquo;
+ </p>
+ <p>
+ Tom had read of such cases, and he at once resolved that he would not only
+ remain in the jewelry shop, but that he would lock the door, which he at
+ once proceeded to do. Then he breathed easier.
+ </p>
+ <p>
+ The town of Shopton, in the outskirts of which Tom lived with his father,
+ and where the scene above narrated took place, was none too well lighted
+ at night, and the lad had his doubts about the jeweler catching the
+ oddly-acting man, especially as the latter had a good start.
+ </p>
+ <p>
+ &ldquo;But some one may head him off,&rdquo; reasoned Tom. &ldquo;Though if they do catch
+ him, I don't see what they can prove against him. Hello, here I am
+ carrying this diamond pin around. I might lose it. Guess I'll put it back
+ on the tray.&rdquo;
+ </p>
+ <p>
+ He replaced in the proper receptacle one of the pins he had been examining
+ when the excitement occurred.
+ </p>
+ <p>
+ &ldquo;I wonder if Mary will like that?&rdquo; he said, softly. &ldquo;I hope she does.
+ Perhaps it would be better if she could come here herself and pick out one&mdash;&rdquo;
+ </p>
+ <p>
+ Tom's musing was suddenly interrupted by a sharp tattoo on the glass door
+ of the jewelry shop. With a start, he looked up, to see staring in on him
+ the face of the man who had been there before&mdash;the man of whom the
+ jeweler was even then in chase.
+ </p>
+ <p>
+ &ldquo;Why&mdash;why&mdash;&mdash;&rdquo; stammered Tom.
+ </p>
+ <p>
+ The man knocked again.
+ </p>
+ <p>
+ &ldquo;Tom&mdash;Tom Swift!&rdquo; he called. &ldquo;Don't you know me?&rdquo;
+ </p>
+ <p>
+ &ldquo;Know you&mdash;you?&rdquo; repeated the lad.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;don't you remember Earthquake Island&mdash;how we were nearly
+ killed there&mdash;don't you remember Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ Tom was so startled that he could only repeat words after the strange man,
+ who was talking to him from outside the glass door.
+ </p>
+ <p>
+ &ldquo;Yes, Mr. Jenks,&rdquo; was the reply. &ldquo;Mr. Barcoe Jenks, who makes diamonds. I
+ saw you in the store about to buy a diamond&mdash;I wanted to tell you not
+ to&mdash;I'll give you a better diamond than you can buy&mdash;I just
+ arrived in this place&mdash;I must have a private talk with you&mdash;Come
+ out&mdash;I'll share a wonderful secret with you.&rdquo;
+ </p>
+ <p>
+ A flood of memory came to Tom. He did recall the very strange man who
+ walked around Earthquake Island&mdash;where Tom and some friends had been
+ marooned recently&mdash;walked about with a pocketful of what he said were
+ diamonds. Now Barcoe Jenks was here.
+ </p>
+ <p>
+ &ldquo;I must see you privately, Tom Swift,&rdquo; went on Mr. Jenks, as he once more
+ tapped on the glass. &ldquo;Don't waste money buying diamonds, when you and I
+ can make better ones. Where can I have a talk with you? I&mdash;&rdquo; Mr.
+ Jenks suddenly looked down the dimly-lighted street. &ldquo;They're coming
+ back!&rdquo; he cried. &ldquo;I don't want to be seen. I'll call at your house later
+ to-night&mdash;be on the watch for me&mdash;until then&mdash;good-by!&rdquo;
+ </p>
+ <p>
+ He waved his hand, and was gone in an instant. Tom stood staring at the
+ glass door. He hardly knew whether to believe it or not&mdash;perhaps it
+ was all a dream.
+ </p>
+ <p>
+ He pinched himself to make sure that he was awake. Very substantial flesh
+ met his thumb and finger, and he felt the pain.
+ </p>
+ <p>
+ &ldquo;I'm awake all right,&rdquo; he murmured. &ldquo;But Barcoe Jenks here&mdash;and still
+ talking that nonsense about his manufactured diamonds. I think he must be
+ crazy. I wonder&mdash;&rdquo;
+ </p>
+ <p>
+ Once more the lad's musing was interrupted. He heard a murmur of excited
+ voices outside the store, on the street. Then the door of the jewelry shop
+ was tried. Mr. Track's face was pressed against the glass.
+ </p>
+ <p>
+ &ldquo;Open the door! Let me in, Tom!&rdquo; he called. &ldquo;I've caught the thief,&rdquo; and
+ as the lad unlocked the portal he saw that the jeweler held by the arm a
+ ragged lad. &ldquo;Ah; you scoundrel! I've caught you!&rdquo; cried the diamond
+ merchant, shaking the small chap, while Tom looked on, more mystified than
+ ever.

+ <h2>
+ CHAPTER II&mdash;A MIDNIGHT VISIT
+ </h2>
+ <p>
+ While Mr. Track, the jeweler, and several citizens, attracted by the chase
+ after the supposed thief, are crowded into the store, anxious to hear
+ explanations of the strange affair, I will take the opportunity to tell
+ you something of Tom Swift, the lad who is to figure in this story.
+ </p>
+ <p>
+ Many of you have already made his acquaintance, when he has been speeding
+ about in his airship or fast electric runabout, and to others we will
+ state that our hero first made his bow to the public in the book called
+ &ldquo;Tom Swift and His Motor-Cycle,&rdquo; the initial volume of this series.
+ </p>
+ <p>
+ In that story there was related how Tom made the acquaintance of an odd
+ individual, named Mr. Wakefield Damon, who was continually blessing
+ himself, some part of his anatomy, or his possessions. Mr. Damon was
+ riding a motor-cycle, and it started to climb a tree, to his pain and
+ fright. Afterward Tom purchased the machine, and had many adventures on
+ it, including a chase after a gang of men who had stolen a valuable patent
+ model belonging to Mr. Swift.
+ </p>
+ <p>
+ Mr. Swift and his son were both inventors. They lived together in a fine
+ house in the suburbs of Shopton, New York, and with them dwelt Mrs.
+ Baggert, the housekeeper (for Tom's mother was dead), and also Garret
+ Jackson, an expert engineer, who aided the young inventor and his father
+ in perfecting many machines.
+ </p>
+ <p>
+ There was also another semi-member of the household, to wit, Eradicate
+ Sampson, an eccentric colored man, who owned a mule called Boomerang.
+ Eradicate did odd jobs around the place, and the mule assisted his owner&mdash;that
+ is when the mule felt like it.
+ </p>
+ <p>
+ In the second volume of the series, entitled &ldquo;Tom Swift and His
+ Motor-Boat,&rdquo; there was related the incidents following a pursuit after a
+ gang of unprincipled men, who sought to get possession of some of Mr.
+ Swift's patents, and it was while in this boat that Tom, his father, and a
+ friend, Ned Newton, rescued from Lake Carlopa a Mr. John Sharp, who fell
+ from his burning balloon. Mr. Sharp was a skilled aeronaut, and after his
+ recovery he joined Tom in building a big airship, called the Red Cloud.
+ Tom's adventures in this craft are set down in detail in the third volume
+ of the series, called &ldquo;Tom Swift and His Airship.&rdquo; Not only did he and Mr.
+ Sharp and Mr. Damon make a great trip, but they captured some bank
+ robbers, and incidentally cleared themselves from the imputation of having
+ looted the vault of seventy-five thousand dollars, which charge was
+ fostered by a certain Mr. Foger, and his son Andy, who was Tom's enemy.
+ </p>
+ <p>
+ Not satisfied with having conquered the air, Tom and his father set to
+ work to gain a victory over the ocean. They built a boat that could
+ navigate under water, and, in the fourth book of the series, called &ldquo;Tom
+ Swift and His Submarine Boat,&rdquo; you will find an account of how they went
+ under the ocean to secure a sunken treasure, and the fight they had with
+ their enemies who sought to get it away from them. They went through many
+ perils, not the least of which was capture by a foreign warship.
+ </p>
+ <p>
+ In the fifth book, entitled &ldquo;Tom Swift and His Electric Runabout,&rdquo; there
+ was told the story of a wonderfully speedy electric automobile the young
+ inventor constructed, and how he made a great race in it, and saved from
+ ruin a bank, in which his father and Mr. Damon were interested.
+ </p>
+ <p>
+ Tom's ability as an inventor had, by this time, become well known. One
+ day, as related in a volume called &ldquo;Tom Swift and His Wireless Message,&rdquo;
+ he received a letter from a Mr. Hosmer Fenwick, of Philadelphia, asking
+ his aid in perfecting an airship which the resident of the Quaker City had
+ built, but which would not work. In his small monoplane, the Butterfly,
+ Tom and Mr. Damon went to Philadelphia, as Mr. Damon was acquainted with
+ Mr. Fenwick.
+ </p>
+ <p>
+ Tom carefully inspected the Whizzer which was the name of Mr. Fenwick's
+ airship, and, after some difficulties, succeeded in getting the electric
+ craft in shape to make a flight.
+ </p>
+ <p>
+ Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape May in the
+ Whizzer, but were caught in a terrific storm, and blown out to sea. The
+ wind became a hurricane, the airship was disabled, and wrecked in mid-air.
+ When it fell to earth it landed on one of the small West Indian islands,
+ but what was the terror of the three castaways to find that the island was
+ subject to earthquake shocks.
+ </p>
+ <p>
+ But the earth-tremors were not the only surprise in store for Tom and his
+ two friends, On the island they found five men and two ladies, who, by
+ strange chance, had been stranded there when the yacht Resolute, owned by
+ Mr. George Hosbrook, was wrecked in the same storm that disabled the
+ airship. Mr. Hosbrook, a millionaire, was taking a party of friends to the
+ West Indies.
+ </p>
+ <p>
+ When the castaways (among whom were Mr. and Mrs. Amos Nestor, parents of
+ Mary Nestor, a girl of whom Tom was very fond) found that there was danger
+ of the island being destroyed in an earthquake, they were in despair.
+ There seemed no way of being rescued, as the island was out of the line of
+ regular ship travel.
+ </p>
+ <p>
+ Tom, however, was resourceful. With the electrical apparatus from the
+ wrecked airship, he built a wireless plant, and sent messages for help,
+ broadcast over the ocean.
+ </p>
+ <p>
+ They were finally heard, and answered, by an operator on board the steamer
+ Camberanian, which came on under forced draught, and rescued Tom and his
+ friends. It was only just in time, for, no sooner had they gotten aboard
+ the steamer in lifeboats, than the whole island was destroyed by an
+ earthquake shock.
+ </p>
+ <p>
+ But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the
+ others, got safely home. Among the survivors from the yacht Resolute was a
+ Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom through
+ the glass window of the jewelry store. Mr. Jenks was a peculiar man. Tom
+ discovered this on Earthquake Island. Mr. Jenks carried with him some
+ stones which he said were diamonds. He asserted that he had made them, but
+ Tom did not know whether or not to believe this.
+ </p>
+ <p>
+ When it seemed that the castaways would not be saved Mr. Jenks offered Tom
+ a large sum in these same diamonds for some plan whereby he might escape
+ the earthquakes. Mr. Jenks said there was a certain secret in connection
+ with the manufactured diamonds that he had to solve&mdash;that he had been
+ defrauded of his rights&mdash;and that a certain Phantom Mountain figured
+ in it. But Tom, at that time, paid little attention to Mr. Jenks' talk.
+ The time was to come, however, when he would attach much importance to it.
+ </p>
+ <p>
+ When this story opens, Tom was more interested in Mr. Barcoe Jenks than in
+ any one else, and was wondering what he wanted to see him about. The young
+ inventor could not quite understand how Mr. Track, the jeweler, could come
+ back with a lad he suspected of being a thief, when the person who had
+ acted so suspiciously, and who had knocked on the glass, was the queer
+ man, Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Yes, Tom I caught him,&rdquo; the jeweler went on. &ldquo;I chased after him, and
+ nabbed him. It was hard work, too, for I'm not a good runner. Now, you
+ little rascal, tell me why you tried to rob my store?&rdquo; and the diamond
+ merchant shook the lad roughly.
+ </p>
+ <p>
+ &ldquo;I&mdash;I didn't try to rob your store,&rdquo; was the timid answer.
+ </p>
+ <p>
+ &ldquo;Well, perhaps you didn't, exactly, but your confederates did. Why did you
+ rap on the glass, and why were you staring in so intently?&rdquo;
+ </p>
+ <p>
+ &ldquo;I wasn't lookin' in.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, if it wasn't you, it was some one just like you. But why did you
+ run when I raced down the street?&rdquo;
+ </p>
+ <p>
+ &ldquo;I&mdash;I don't know,&rdquo; and the lad began to snivel. &ldquo;I&mdash;I jest ran&mdash;that's
+ all&mdash;'cause I see everybody else runnin', an' I thought there was a
+ fire.&rdquo;
+ </p>
+ <p>
+ &ldquo;Ha! That's a likely story! You ran because you are guilty! I'm going to
+ hand you over to the police.&rdquo;
+ </p>
+ <p>
+ &ldquo;Did he get anything, Mr. Track?&rdquo; asked one of the men who had joined the
+ jeweler in the chase.
+ </p>
+ <p>
+ &ldquo;No, I can't say that he did. He didn't get a chance. Tom Swift was in
+ here at the time. But this fellow was only waiting for a chance to steal,
+ or else to aid his confederates.&rdquo;
+ </p>
+ <p>
+ &ldquo;But, if he didn't take anything, I don't see how you can have him
+ arrested,&rdquo; went on the man.
+ </p>
+ <p>
+ &ldquo;On suspicion; that's how!&rdquo; asserted Mr. Track. &ldquo;Will some one get me a
+ constable?&rdquo;
+ </p>
+ <p>
+ &ldquo;I wouldn't call a constable,&rdquo; said Tom, quietly.
+ </p>
+ <p>
+ &ldquo;Why not?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because that isn't the person who looked in your window.&rdquo;
+ </p>
+ <p>
+ &ldquo;How do you know, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because that person came back while you were out. I saw him.&rdquo;
+ </p>
+ <p>
+ &ldquo;You saw him? Did he try to steal any of my diamonds, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;No, I guess he doesn't need any.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why not?&rdquo; There was wonder in the jeweler's tone.
+ </p>
+ <p>
+ &ldquo;Why, he claims he can make all he wants.&rdquo;
+ </p>
+ <p>
+ &ldquo;Make diamonds?&rdquo;
+ </p>
+ <p>
+ &ldquo;So he says.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why, he must be crazy!&rdquo; and Mr. Track laughed.
+ </p>
+ <p>
+ &ldquo;Perhaps he is,&rdquo; admitted Tom, &ldquo;I'm only telling you what he says. He's
+ the person who acted so suspiciously. He came back here, I'm telling you,
+ while you were running down the street, and spoke to me.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, then you know him?&rdquo; The jeweler's voice was suspicious.
+ </p>
+ <p>
+ &ldquo;I didn't at first,&rdquo; admitted Tom. &ldquo;But when he said he was Mr. Barcoe
+ Jenks, I remembered that I had met him when I was cast away on Earthquake
+ Island.&rdquo;
+ </p>
+ <p>
+ &ldquo;And he says he can make diamonds?&rdquo; asked Mr. Track.
+ </p>
+ <p>
+ &ldquo;What did he want of you?&rdquo; and the jeweler looked at Tom, quizzically.
+ </p>
+ <p>
+ &ldquo;He wanted to have a talk with me,&rdquo; replied the lad, &ldquo;and when he saw me
+ in your store, he tried to attract my attention by knocking on the glass.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's a queer way to do,&rdquo; declared Mr. Track. &ldquo;What did he want?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know exactly,&rdquo; answered Tom, not caring to go into details just
+ then. &ldquo;But I'm sure, Mr. Track, that you've got the wrong person there.
+ That lad never looked in the window, nor knocked on the glass.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's right&mdash;I didn't,&rdquo; asserted the captive.
+ </p>
+ <p>
+ The jeweler looked doubtful.
+ </p>
+ <p>
+ &ldquo;Why did you run?&rdquo; he asked.
+ </p>
+ <p>
+ &ldquo;I told you, I thought there was a fire.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's right, I don't believe he's the fellow you want,&rdquo; put in another
+ man. &ldquo;I was standing on the corner, near White's grocery store, and I
+ noticed this lad. That was before I heard you yelling, and saw you coming,
+ and then I joined in the chase. I guess the man you were after got away,
+ Track.&rdquo;
+ </p>
+ <p>
+ &ldquo;He did,&rdquo; asserted Tom. &ldquo;He came back here, a little while ago, and he ran
+ away just now, as he heard you coming.&rdquo;
+ </p>
+ <p>
+ &ldquo;Where did he go?&rdquo; asked the jeweler, eagerly.
+ </p>
+ <p>
+ &ldquo;I don't know,&rdquo; answered Tom. &ldquo;Only you've got the wrong lad here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, perhaps I have,&rdquo; admitted the diamond merchant. &ldquo;You can go,
+ youngster, but next time, don't run if you're not guilty.&rdquo;
+ </p>
+ <p>
+ &ldquo;I thought there was a fire,&rdquo; repeated the lad, as he hurriedly slipped
+ through the crowd in the store, and disappeared down the dark street.
+ </p>
+ <p>
+ &ldquo;Well, I guess the excitement's all over, and, anyhow, you weren't robbed,
+ Track,&rdquo; said a stout man, as he left the store. The others soon followed,
+ and Tom and the jeweler were once more alone in the shop.
+ </p>
+ <p>
+ &ldquo;Can you tell me something about this man, Tom?&rdquo; asked Mr. Track, eagerly.
+ &ldquo;So he really makes diamonds. Who is he?&rdquo;
+ </p>
+ <p>
+ &ldquo;I'd rather not tell&mdash;just now,&rdquo; replied the young inventor. &ldquo;I don't
+ take much stock in him, myself. I think he's visionary. He may think he
+ has made diamonds, and he may have made some stones that look like them.
+ I'm very skeptical.&rdquo;
+ </p>
+ <p>
+ &ldquo;If you could bring me some, Tom, I could soon tell whether they were real
+ or not. Can you?&rdquo;
+ </p>
+ <p>
+ The lad shook his head.
+ </p>
+ <p>
+ &ldquo;I don't expect to see Mr. Jenks again,&rdquo; he said. &ldquo;He talked rather wildly
+ about waiting to meet me, but that man is odd&mdash;crazy, perhaps&mdash;and
+ I don't imagine I'll see him. He's harmless, but he's eccentric. Well,
+ there was quite some excitement for a time.&rdquo;
+ </p>
+ <p>
+ &ldquo;I should say there was. I thought it was a plan to rob me,&rdquo; and the
+ jeweler began putting away the diamond pins. In fact, the excitement so
+ filled the minds of himself and Tom that neither of them thought any more
+ of the object of the lad's visit, and the young inventor departed without
+ purchasing the pin he had come after.
+ </p>
+ <p>
+ It was not until he was out on the street, walking toward his home, that
+ the matter came back to his mind.
+ </p>
+ <p>
+ &ldquo;I declare!&rdquo; he exclaimed. &ldquo;I didn't get that pin for Mary, after all!
+ Well, never mind, I have a week until her birthday, and I can get it
+ to-morrow.&rdquo;
+ </p>
+ <p>
+ He walked rapidly toward home, for the weather looked threatening, and Tom
+ had no umbrella. He was musing on the happenings of the evening when he
+ reached his house. His father was out, as was Garret Jackson, the
+ engineer; and Mrs. Baggert, the housekeeper, was entertaining a lady in
+ the sitting-room, so, as Tom was rather tired, he went directly to his own
+ room, and, a little later got into bed.
+ </p>
+ <p>
+ It was shortly after midnight when he was awakened by hearing a rattling
+ on the window of his room. The reason he was able to fix the time so
+ accurately was because as soon as he awakened he pressed a little electric
+ button, and it illuminated the face of a small clock on his bureau. The
+ hands pointed to five minutes past twelve.
+ </p>
+ <p>
+ &ldquo;Humph! That sounds like hail!&rdquo; exclaimed Tom, as he arose, and looked out
+ of the casement. &ldquo;I wonder if any of the skylights of the airship shed are
+ open? There might be some damage. Guess I'd better go out and take a
+ look.&rdquo;
+ </p>
+ <p>
+ He had mentally reasoned this far before he had looked out, and when he
+ saw that the moon was brightly shining in a clear sky, he was a bit
+ surprised.
+ </p>
+ <p>
+ &ldquo;Why&mdash;that wasn't hail,&rdquo; he murmured. &ldquo;It isn't even raining. I
+ wonder what it was?&rdquo;
+ </p>
+ <p>
+ He was answered a moment later, for a shower of fine gravel from the walk
+ flew up and clattered against the glass. With a start, Tom looked down,
+ and saw a dark figure standing under an apple tree.
+ </p>
+ <p>
+ &ldquo;Hello! Who's there?&rdquo; called the lad, after he had raised the sash.
+ </p>
+ <p>
+ &ldquo;It's I&mdash;Mr. Jenks,&rdquo; was the surprising answer.
+ </p>
+ <p>
+ &ldquo;Mr. Jenks?&rdquo; repeated Tom.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;Barcoe Jenks, of Earthquake Island.&rdquo;
+ </p>
+ <p>
+ &ldquo;You here? What do you want?&rdquo;
+ </p>
+ <p>
+ &ldquo;Can you come down?&rdquo;
+ </p>
+ <p>
+ &ldquo;What for?&rdquo;
+ </p>
+ <p>
+ &ldquo;Tom Swift, I've something very important to tell you,&rdquo; was the answer in
+ a low voice, yet which carried to Tom's ears perfectly. &ldquo;Do you want to
+ make a fortune for yourself&mdash;and for me?&rdquo;
+ </p>
+ <p>
+ &ldquo;How?&rdquo; Tom was beginning to think more and more that Mr. Jenks was crazy.
+ </p>
+ <p>
+ &ldquo;How? By helping me to discover the secret of Phantom Mountain, where the
+ diamonds are made! Will you?&rdquo;
+ </p>
+ <p>
+ &ldquo;Wait a minute&mdash;I'll come down,&rdquo; answered Tom, and he began to grope
+ for his clothes in the dim light of the little electric lamp.
+ </p>
+ <p>
+ What was the secret of Phantom Mountain? What did Mr. Jenks really want?
+ Could he make diamonds? Tom asked himself these questions as he hastily
+ dressed to go down to his midnight visitor.

+ <h2>
+ CHAPTER III&mdash;A STRANGE STORY
+ </h2>
+ <p>
+ &ldquo;Well, Mr. Jenks,&rdquo; began Tom, when he had descended to the garden, and
+ greeted the man who had acted so strangely on Earthquake Island, &ldquo;this is
+ rather an odd time for a visit.&rdquo;
+ </p>
+ <p>
+ &ldquo;I realize that, Tom Swift,&rdquo; was the answer, and the lad noticed that the
+ man spoke much more calmly than he had that evening at the jewelry shop.
+ &ldquo;I realize that, but I have to be cautious in my movements.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because there are enemies on my track. If they thought I was seeking aid
+ to discover the secret of Phantom Mountain, my life might pay the
+ forfeit.&rdquo;
+ </p>
+ <p>
+ &ldquo;Are you in earnest, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I certainly am, and, while I must apologize for awakening you at this
+ unseemly hour, and for the mysterious nature of my visit, if you will let
+ me tell my story, you will see the need of secrecy.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I don't mind being awakened,&rdquo; answered Tom, good-naturedly, &ldquo;but I
+ will be frank with you, Mr. Jenks. I hardly can believe what you have
+ stated to me several times&mdash;that you know how diamonds can be made.&rdquo;
+ </p>
+ <p>
+ &ldquo;I can prove it to you,&rdquo; was the quiet answer.
+ </p>
+ <p>
+ &ldquo;Yes, I know. For centuries men have tried to discover the secret of
+ transmuting base metals into gold, and how to make diamonds by chemical
+ means. But they have all been failures.&rdquo;
+ </p>
+ <p>
+ &ldquo;All except this process&mdash;the process used at Phantom Mountain,&rdquo;
+ insisted the queer man. &ldquo;Do you want to hear my story?&rdquo;
+ </p>
+ <p>
+ &ldquo;I have no objections.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then let me warn you,&rdquo; went on Mr. Jenks, &ldquo;that if you do hear it, you
+ will be so fascinated by it that I am sure you will want to cast your lot
+ in with mine, and aid me to get my rights, and solve the mystery. And I
+ also want to warn you that if you do, there is a certain amount of danger
+ connected with it.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm used to danger,&rdquo; answered Tom, quietly. &ldquo;Let me hear your story. But
+ first explain how you came to come here, and why you acted so strangely at
+ the jewelry store.&rdquo;
+ </p>
+ <p>
+ &ldquo;Willingly. I tried to attract your attention at the store, because I saw
+ that you were going to buy a diamond, and I didn't want you to.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why not?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because I want to present you with a beautiful stone, that will answer
+ your purpose as well or better, than any one you could buy. That will
+ prove my story better than any amount of words or argument. But I could
+ not attract your attention without also attracting that of the jeweler. He
+ became suspicious, gave chase, and I thought it best to vanish. I hope no
+ one was made to suffer for what may have been my imprudence.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, the lad whom Mr. Track caught was let go. But how did you happen to
+ come to Shopton?&rdquo;
+ </p>
+ <p>
+ &ldquo;To see you. I got your address from the owner of the yacht Resolute. I
+ knew that if there was one person who could aid me to recover my rights,
+ it would be you, Tom Swift. Will you help me? Will you come with me to
+ discover the secret of Phantom Mountain? If we go, it will have to be in
+ an airship, for in no other way, I think, can we come upon the place, as
+ it is closely guarded. Will you come? I will pay you well.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps I had better hear your story,&rdquo; said the young inventor. &ldquo;But
+ first let me suggest that we move farther away from the house. My father,
+ or Mr. Jackson, or the housekeeper, may hear us talking, and it may
+ disturb them. Come with me to my private shop,&rdquo; and Tom led the way to a
+ small building where he did experimental work. He unlocked the door with a
+ key he carried, turned on the lights, which were run by a storage battery,
+ and motioned Mr. Jenks to a seat.
+ </p>
+ <p>
+ &ldquo;Now I'll hear your story,&rdquo; said Tom.
+ </p>
+ <p>
+ &ldquo;I'll make it as short as possible,&rdquo; went on the queer man. &ldquo;To begin
+ with, it is now several years ago since a poorly dressed stranger applied
+ to me one night for money enough to get a meal and a bed to sleep in. I
+ was living in New York City at the time, and this was midnight, as I was
+ returning home from my club.
+ </p>
+ <p>
+ &ldquo;I was touched by the man's appearance, and gave him some money. He asked
+ for my card, saying he would repay me some day. I gave it to him, little
+ thinking I would hear from the man again. But I did. He called at my
+ apartments about a week later, saying he had secured work as an expert
+ setter of diamonds, and wanted to repay me. I did not want to take his
+ money, but the fact that such a sorry looking specimen of manhood as he
+ had been when I aided him, was an expert handler of gems interested me. I
+ talked with the man, and he made a curious statement.
+ </p>
+ <p>
+ &ldquo;This man, who gave his name as Enos Folwell, said he knew a place where
+ diamonds could be made, partly in a scientific manner, and partly by the
+ forces of nature. I laughed at him, but he told me so many details that I
+ began to believe him. He said he and some other friends of his, who were
+ diamond cutters, had a plant in the midst of the Rocky Mountains, where
+ they had succeeded in making several small, but very perfect diamonds.
+ They had come to the end of their rope, though, so to speak, because they
+ could not afford to buy the materials needed. Folwell said that he and his
+ companions had temporarily separated, had left the mountain where they
+ made diamonds, and agreed to meet there later when they had more money
+ with which to purchase materials. They had all agreed to go out into
+ civilization, and work for enough funds to enable them to go on with their
+ diamond making.
+ </p>
+ <p>
+ &ldquo;I hardly knew whether to believe the man or not, but he offered proof. He
+ had several small, but very perfect diamonds with him, and he gave them to
+ me, to have tested in any way I desired.
+ </p>
+ <p>
+ &ldquo;I promised to look into the matter, and, as I was quite wealthy, as, in
+ fact I am now, and if I found that the stones he gave me were real, I said
+ I might invest some money in the plant.&rdquo;
+ </p>
+ <p>
+ &ldquo;Were the diamonds good?&rdquo; asked Tom, who was beginning to be interested.
+ </p>
+ <p>
+ &ldquo;They were&mdash;stones of the first water, though small. An expert gem
+ merchant, to whom I took them, said he had never seen any diamonds like
+ them, and he wanted to know where I got them. Of course I did not tell
+ him.
+ </p>
+ <p>
+ &ldquo;To make a long story short, I saw Folwell again, told him to communicate
+ with his companions, and to tell them that I would agree to supply the
+ cash needed, if I could share in the diamond making. To this they agreed,
+ and, after some weeks spent in preparation, a party of us set out for
+ Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Phantom Mountain?&rdquo; interrupted Tom. &ldquo;Where is it?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know, exactly&mdash;it's somewhere in the Rockies, but the exact
+ location is a mystery. That is why I need your help. You will soon
+ understand the reason. Well, as I said, myself, Folwell and the others,
+ who were not exactly prepossessing sort of men, started west. When we got
+ to a small town, called Indian Ridge, near Leadville, Colorado, the men
+ insisted that I must now proceed in secret, and consent to be blindfolded,
+ as they were not yet ready to reveal the secret of the place where they
+ made the diamonds.
+ </p>
+ <p>
+ &ldquo;I did not want to agree to this, but they insisted, and I gave in,
+ foolishly perhaps. At any rate I was blindfolded one night, placed in a
+ wagon, and we drove off into the mountains. After traveling for some
+ distance I was led, still blindfolded, up a steep trail.
+ </p>
+ <p>
+ &ldquo;When the bandage was taken off my eyes I saw that I was in a large cave.
+ The men were with me, and they apologized for the necessity that caused
+ them to blindfold me. They said they were ready to proceed with the making
+ of diamonds, but I must promise not to seek to discover the secret until
+ they gave me permission, nor was I to attempt to leave the cave. I had to
+ agree.
+ </p>
+ <p>
+ &ldquo;Next they demanded that I give them a large sum, which I had promised
+ when they showed me, conclusively, that they could make diamonds. I
+ refused to do this until I had seen some of the precious stones, and they
+ agreed that this was fair, but said I would have to wait a few days.
+ </p>
+ <p>
+ &ldquo;Well, I waited, and, all that while, I was virtually a prisoner in the
+ cave. All I could learn was that it was in the midst of a great range,
+ near the top, and that one of the peaks was called Phantom Mountain. Why,
+ I did not learn until later.
+ </p>
+ <p>
+ &ldquo;At last one night, during a terrific thunder storm, the leader of the
+ diamond makers&mdash;Folwell&mdash;announced that I could now see the
+ stones made. The men had been preparing their chemicals for some days
+ previous. I was taken into a small chamber of the cave, and there saw
+ quite a complicated apparatus. Part of it was a great steel box, with a
+ lever on it.
+ </p>
+ <p>
+ &ldquo;We will let you make some diamonds for yourself,&rdquo; Folwell said to me, and
+ he directed me to pull the lever of the box, at a certain signal. The
+ signal came, just as a terrific crash of thunder shook the very mountain
+ inside of which we were. The box of steel got red-hot, and when it cooled
+ off it was opened, and was given a handful of white stones.
+ </p>
+ <p>
+ &ldquo;Were they diamonds?&rdquo; asked Tom, eagerly.
+ </p>
+ <p>
+ Mr. Jenks held out one hand. In the palm glittered a large stone&mdash;ostensibly
+ a diamond. In the rays of the moon it showed all the colors of the rainbow&mdash;a
+ beautiful gem. &ldquo;That is one of the stones I made&mdash;or rather that I
+ supposed I had made,&rdquo; went on Mr. Jenks. &ldquo;It is one of several I have, but
+ they have not all been cut and polished as has this one.
+ </p>
+ <p>
+ &ldquo;Naturally I was much impressed by what I saw, and, after I had made
+ certain tests which convinced me that the stones in the steel box were
+ diamonds, I paid over the money as I had promised. That was my undoing.&rdquo;
+ </p>
+ <p>
+ &ldquo;How?&rdquo;
+ </p>
+ <p>
+ &ldquo;As soon as the men got the cash, they had no further use for me. The next
+ I remember is eating a rude meal, while we discussed the future of making
+ diamonds. I knew nothing more until I found myself back in the small hotel
+ at Indian Ridge, whence I had gone some time previous, with the men, to
+ the cave in the mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;What happened?&rdquo; asked Tom, much surprised by the unexpected outcome of
+ the affair.
+ </p>
+ <p>
+ &ldquo;I had been tricked, that was all! As soon as the men had my money they
+ had no further use for me. They did not want me to learn the secret of
+ their diamond making, and they drugged me, carried me away from the cave,
+ and left me in the hotel.&rdquo;
+ </p>
+ <p>
+ &ldquo;Didn't you try to find the cave again?&rdquo;
+ </p>
+ <p>
+ &ldquo;I did, but without avail. I spent some time in the Rockies, but no one
+ could tell where Phantom Mountain was; in fact, few had heard of it, and I
+ was nearly lost searching for it.
+ </p>
+ <p>
+ &ldquo;I came back East, determined to get even. I had given the men a very
+ large sum of money, and, in exchange, they had given me several diamonds.
+ Probably the stones are worth nearly as much as the money I invested, but
+ I was cheated, for I was promised an equal share in the profits. These
+ were denied me, and I was tricked. I determined to be revenged, or at
+ least to discover the secret of making diamonds. It is my right.&rdquo;
+ </p>
+ <p>
+ &ldquo;I agree with you,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;But, up to the time I met you on Earthquake Island, I could form no plan
+ for discovering Phantom Mountain, and learning the secret of the diamond
+ makers,&rdquo; went on Mr. Jenks. &ldquo;I carried the gems about with me, as you
+ doubtless saw when we were on the island. But I knew I needed an airship
+ in which to fly over the mountains, and pick out the location of the cave
+ where the diamonds are made.&rdquo;
+ </p>
+ <p>
+ &ldquo;But how can you locate it, if you were blindfolded when you were taken
+ there, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I forgot to tell you that, on our journey into the mountains, and just
+ before I was carried into the cave, I managed to raise one corner of the
+ bandage. I caught a glimpse of a very peculiarly shaped cliff&mdash;it is
+ like a great head, standing out in bold relief against the moonlight, when
+ I saw it. That head of rock is near the cave. It may be the landmark by
+ which we can locate Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps,&rdquo; admitted the young inventor.
+ </p>
+ <p>
+ &ldquo;What I want to know is this,&rdquo; went on Mr. Jenks. &ldquo;Will you go with me on
+ this quest&mdash;go in your airship to discover the secret of the diamond
+ makers? If you will, I will share with you whatever diamonds we can
+ discover, or make; besides paying all expenses. Will you go, Tom Swift?&rdquo;
+ </p>
+ <p>
+ The young inventor did not know what to answer. How far was Mr. Jenks to
+ be trusted? Were the stones he had real diamonds? Was his story,
+ fantastical as it sounded&mdash;true? Would it be safe for Tom to go?
+ </p>
+ <p>
+ The lad asked himself these questions. Mr. Jenks saw his hesitation.
+ </p>
+ <p>
+ &ldquo;Here,&rdquo; said the strange man, &ldquo;I will prove what I say. Take this diamond.
+ I intended it for you, anyhow, for what you did for me on Earthquake
+ Island. Take it, and&mdash;and give it to the person for whom you were
+ about to purchase a diamond to-night. But, first of all, take it to a gem
+ expert, and get his opinion. That will prove the truth of what I say, Tom
+ Swift, and I feel sure that you will cast your lot in with mine, and help
+ me to discover the secret of Phantom Mountain, and aid me to get my rights
+ from the diamond makers!&rdquo;

+ <h2>
+ CHAPTER IV&mdash;ANDY FOGER GETS A FRIGHT
+ </h2>
+ <p>
+ Tom Swift considered a few minutes. On the face of it, the proposition
+ appealed to him. He had been home some time now after his adventures on
+ Earthquake Island, and he was beginning to long for more excitement. The
+ search for the mysterious mountain, and the cave of the diamond makers,
+ might offer a new field for him. But there came to him a certain distrust
+ of Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I don't like to doubt your word,&rdquo; began Tom, slowly, &ldquo;but you know, Mr.
+ Jenks, that some of the greatest chemists have tried in vain to make
+ diamonds; or, at best, they have made only tiny ones. To think that any
+ man, or set of men, made real diamonds as large as the ones you have,
+ doesn't seem&mdash;well&mdash;&rdquo; and Tom hesitated.
+ </p>
+ <p>
+ &ldquo;You mean you can hardly believe me?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I guess that's it,&rdquo; assented Tom.
+ </p>
+ <p>
+ &ldquo;I don't blame you a bit!&rdquo; exclaimed the odd man. &ldquo;In fact, I didn't
+ believe it when they told me they could make diamonds. But they proved it
+ to me. I'm ready now to prove it to you.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll tell you what I'll do. Here's this one stone, cut ready for setting.
+ Here's another, uncut,&rdquo; and Mr. Jenks drew from his pocket what looked
+ like a piece of crystal. &ldquo;Take them to any jeweler,&rdquo; he resumed&mdash;&ldquo;to
+ the one in whose place I saw you to-night. I'll abide by the verdict you
+ get, and I'll come here to-morrow night, and hear what you have to say.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why do you come at night?&rdquo; asked Tom, thinking there was something
+ suspicious in that.
+ </p>
+ <p>
+ &ldquo;Because my life might be in danger if I was seen talking to you, and
+ showing you diamonds in the daytime&mdash;especially just now.
+ </p>
+ <p>
+ &ldquo;Why at this particular time?&rdquo;
+ </p>
+ <p>
+ &ldquo;For the reason that the diamond makers are on my trail. As long as I
+ remained quiet, after their shabby treatment of me, and did not try to
+ discover their secret, they were all right. But, after I realized that I
+ had been cheated out of my rights, and when I began to make an
+ investigation, with a view to discovering their secret whereabouts, I
+ received mysterious and anonymous warnings to stop.&rdquo;
+ </p>
+ <p>
+ &ldquo;But I did not. I came East, and tried to get help to discover the cave of
+ the diamond makers, but I was unsuccessful. I needed an airship, as I said,
+ and no person who could operate one, would agree to go with me on the
+ quest. Again I received a warning to drop all search for the diamond
+ makers, but I persisted, and about a week ago I found I was being
+ shadowed.&rdquo;
+ </p>
+ <p>
+ &ldquo;Shadowed; by whom?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;By a man I never remember seeing, but who, I have no doubt, is one of the
+ diamond-making gang.&rdquo;
+ </p>
+ <p>
+ &ldquo;Do you think he means you harm?&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm sure of it. That is the reason I have to act so in secret, and come
+ to see you at night. I don't want those scoundrels to find out what I am
+ about to do. On my return from Earthquake Island, I again endeavored to
+ interest an airship man in my plan, but he evidently thought me insane.
+ Then I thought of you, as I had done before, but I was afraid you, too,
+ would laugh at my proposition. However, I decided to come here, and I did.
+ It seemed almost providential that my first view of you was in a jewelry
+ shop, looking at diamonds. I took it as a good omen. Now it remains with
+ you. May I call here to-morrow night, and get your answer?&rdquo;
+ </p>
+ <p>
+ Tom Swift made up his mind quickly. After all it would be easy enough to
+ find out if the diamonds were real. If they were, he could then decide
+ whether or not to go with Mr. Jenks on the mysterious quest. So he
+ answered:
+ </p>
+ <p>
+ &ldquo;I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow night.
+ In the meanwhile, for my own satisfaction, I'll let an expert look at
+ these stones.&rdquo;
+ </p>
+ <p>
+ &ldquo;Get the greatest diamond expert in the world, and he'll pronounce them
+ perfect!&rdquo; predicted the odd man. &ldquo;Now I'll bid you goodnight, and be
+ going. I'll be here at this time to-morrow.&rdquo;
+ </p>
+ <p>
+ As Mr. Jenks turned aside there was a movement among the trees in the
+ orchard, and a shadowy figure was seen hurrying away.
+ </p>
+ <p>
+ &ldquo;Who's that?&rdquo; asked the diamond man, in a hoarse whisper. &ldquo;Did you see
+ that, Tom Swift? Some one was here&mdash;listening to what I said! Perhaps
+ it was the man who has been shadowing me!&rdquo;
+ </p>
+ <p>
+ &ldquo;I think not. I guess it was Eradicate Sampson, a colored man who does
+ work for us,&rdquo; said Tom. &ldquo;Is that you, Rad?&rdquo; he called.
+ </p>
+ <p>
+ &ldquo;Yais, sah, Massa Tom, heah I is!&rdquo; answered the voice of the negro, but it
+ came from an entirely different direction than that in which the shadowy
+ figure had been seen.
+ </p>
+ <p>
+ &ldquo;Where are you, Rad?&rdquo; called the young inventor.
+ </p>
+ <p>
+ &ldquo;Right heah,&rdquo; was the reply, and the colored man came from the direction
+ of the stable. &ldquo;I were jest out seein' if mah mule Boomerang were all
+ right. Sometimes he's restless, an' don't sleep laik he oughter.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then that wasn't you over in the orchard?&rdquo; asked Tom, in some uneasiness.
+ </p>
+ <p>
+ &ldquo;No, sah, I ain't been in de orchard. I were sleepin' in mah shack, till
+ jest a few minutes ago, when I got up, an' went in t' see Boomerang. I had
+ a dream dat some coon were tryin t' steal him, an' it sort ob 'sturbed me,
+ laik.&rdquo;
+ </p>
+ <p>
+ &ldquo;If it wasn't your man, it was some one else,&rdquo; said Mr. Jenks, decidedly.
+ </p>
+ <p>
+ &ldquo;We'll have a look!&rdquo; exclaimed Tom. &ldquo;Here, Rad, come over and scurry among
+ those trees. We just saw some one sneaking around.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll sure do dat!&rdquo; cried the colored man. &ldquo;Mebby it were somebody arter
+ Boomerang! I'll find 'em.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe it was any one after the mule,&rdquo; murmured Mr. Jenks, &ldquo;but
+ it certainly was some one&mdash;more likely some one after me.&rdquo;
+ </p>
+ <p>
+ The three made a hasty search among the trees, but the intruder had
+ vanished, leaving no trace. They went out into the road, which the moon
+ threw into bold relief along its white stretch, but there was no figure
+ scurrying away.
+ </p>
+ <p>
+ &ldquo;Whoever it was, is gone,&rdquo; spoke Tom. &ldquo;You can go back to bed, Rad,&rdquo; for
+ the colored man, of late, had been sleeping in a shack on the Swift
+ premises.
+ </p>
+ <p>
+ &ldquo;And I guess it's time for me to go, too,&rdquo; added Mr. Jenks. &ldquo;I'll be here
+ to-morrow night, Tom, and I hope your answer will be favorable.&rdquo;
+ </p>
+ <p>
+ Tom did not sleep well the remainder of the night, for his fitful slumbers
+ were disturbed by dreams of enormous caves, filled with diamonds, with
+ dark, shadowy figures trying to put him into a red-hot steel box. Once he
+ awakened with a start, and put his hand under his pillow to feel if the
+ two stones Mr. Jenks had given him, were still there. They had not been
+ disturbed.
+ </p>
+ <p>
+ Tom made up his mind to find out if the stones were really diamonds,
+ before saying anything to his father about the chance of going to seek
+ Phantom Mountain. And the young inventor wished to get the opinion of some
+ other jeweler than Mr. Track&mdash;at least, at first.
+ </p>
+ <p>
+ &ldquo;Though if this one proves to be a good gem, I'll have Mr. Track set it in
+ a brooch, and give it to Mary for her birthday,&rdquo; decided the young
+ inventor. &ldquo;Guess I'll take a run over to Chester in the Butterfly, and see
+ what one of the jewelers there has to say.&rdquo;
+ </p>
+ <p>
+ In addition to his big airship, Red Cloud, Tom owned a small, swift
+ monoplane, which he called Butterfly. This had been damaged by Andy Foger
+ just before Tom left on the trip that ended at Earthquake Island, but the
+ monoplane had been repaired, and Andy had left town, not having returned
+ since.
+ </p>
+ <p>
+ Telling his father that he was going off on a little business trip, which
+ he often did in his aeroplane, Tom, with the aid of Mr. Jackson, the
+ engineer, wheeled the Butterfly out of its shed.
+ </p>
+ <p>
+ Adjusting the mechanism, and seeing that it was in good shape, Tom took
+ his place in one of the two seats, for the monoplane would carry two. Mr.
+ Jackson then spun the propellers, and, with a crackle and roar the motor
+ started. Over the ground ran the dainty, little aeroplane, until, having
+ momentum enough, Tom tilted the wing planes and the machine sailed up into
+ the air.
+ </p>
+ <p>
+ Rising about a thousand feet, and circling about several times to test the
+ wind currents, Tom headed his craft toward Chester, a city about fifty
+ miles from Shopton. In his pocket, snugly tucked away, were the two stones
+ Mr. Jenks had given him.
+ </p>
+ <p>
+ It was not long before Tom saw, looming up in the distance the church
+ spires and towering factory chimneys of Chester, for his machine was a
+ speedy one, and could make ninety miles an hour when driven. But now a
+ slower speed satisfied our hero.
+ </p>
+ <p>
+ &ldquo;I'll just drop down outside of the city,&rdquo; he reasoned, &ldquo;for too much of a
+ crowd gathers when I land in the street. Besides I might frighten horses,
+ and then, too, it's hard to get a good start from the street. I'll leave
+ it in some barn until I want to go back.&rdquo;
+ </p>
+ <p>
+ Tom sent his craft down, in order to pick out a safe place for a landing.
+ He was then over the suburbs of the city, and was following the line of a
+ straight country road.
+ </p>
+ <p>
+ &ldquo;Looks like a good place there,&rdquo; he murmured. &ldquo;I'll shut off the motor,
+ and vol-plane down.&rdquo;
+ </p>
+ <p>
+ Suiting the action to the word, Tom shut off his power. The little craft
+ dipped toward the ground, but the lad threw up the forward planes, and
+ caught a current of air that sent him skimming along horizontally.
+ </p>
+ <p>
+ As he got nearer to the ground, he saw the figure of a lad riding a
+ bicycle along the country highway. Something about the figure struck Tom
+ as being familiar, and he recognized the cyclist a moment later.
+ </p>
+ <p>
+ &ldquo;It's Andy Foger!&rdquo; said Tom, in a whisper. &ldquo;I wondered where he had been
+ keeping himself since he damaged the Butterfly. Evidently he doesn't dare
+ venture back to Shopton. Well, here's where I give him a scare.&rdquo;
+ </p>
+ <p>
+ Tom's monoplane was making no more noise, now, than a soaring bird. He was
+ gliding swiftly toward the earth, and, with the plan in his mind of
+ administering some sort of punishment to the bully, he aimed the machine
+ directly at him.
+ </p>
+ <p>
+ Nearer and nearer shot the monoplane, as quietly as a sheet of paper might
+ fall. Andy pedaled on, never looking up nor behind him, A moment later, as
+ Tom threw up his headplanes, to make his landing more easy, and just as he
+ swooped down at one side of the cyclist, our hero let out a most alarming
+ yell, right into Andy's ear.
+ </p>
+ <p>
+ &ldquo;Now I've got you!&rdquo; he shouted. &ldquo;I'll teach you to slash my aeroplane!
+ Come with me!&rdquo;
+ </p>
+ <p>
+ Andy gave one look at the white bird-like apparatus that had flown up
+ beside him so noiselessly, and, being too frightened to recognize Tom's
+ voice, must have thought that he had been overtaken by some supernatural
+ visitor.
+ </p>
+ <p>
+ Andy gave a yell like an Indian, about to do a stage scalping act, and
+ fairly dived over the handlebars of his bicycle, sprawling in a heap on
+ the dusty road.
+ </p>
+ <p>
+ &ldquo;I guess that will hold you for a while,&rdquo; observed Tom, grimly, as he put
+ on the ground-brake and brought his monoplane to a stop not far from the
+ fallen rider.

+ <h2>
+ CHAPTER V&mdash;A MYSTERIOUS MAN
+ </h2>
+ <p>
+ For several minutes Andy Foger did not arise. He remained prostrate in the
+ dust, and Tom, observing him, thought perhaps the bully might have been
+ seriously injured. But, a little later, Andy cautiously raised his head,
+ and inquired in a frightened voice:
+ </p>
+ <p>
+ &ldquo;Is it&mdash;is it gone?&rdquo;
+ </p>
+ <p>
+ &ldquo;Is what gone?&rdquo; asked Tom, grimly.
+ </p>
+ <p>
+ At the sound of his voice, Andy looked up. &ldquo;Was that you, Tom Swift?&rdquo; he
+ demanded. &ldquo;Did you knock me off my wheel?&rdquo;
+ </p>
+ <p>
+ &ldquo;My monoplane and I together did,&rdquo; was the reply; &ldquo;or, rather, we didn't.
+ It was the nervous reaction caused by your fright, and the knowledge that
+ you had done wrong, that made you jump over the handlebars. That's the
+ scientific explanation.&rdquo;
+ </p>
+ <p>
+ &ldquo;You&mdash;you did it!&rdquo; stammered Andy, getting to his feet. He wasn't
+ hurt much, Tom thought.
+ </p>
+ <p>
+ &ldquo;Have it your own way,&rdquo; resumed our hero. &ldquo;Did you think it was a
+ hob-goblin in a chariot of fire after you, Andy?&rdquo;
+ </p>
+ <p>
+ &ldquo;Huh! Never mind what I thought! I'll have you arrested for this!&rdquo;
+ </p>
+ <p>
+ &ldquo;Will you? Delighted, as the boys say. Hop in my airship and I'll take you
+ right into town. And when I get you there I'll make a charge of malicious
+ mischief against you, for breaking the propeller of the Butterfly and
+ slashing her wings. I've mended her up, however, so she goes better than
+ ever, and I can take you to the police station in jig time. Want to come,
+ Andy?&rdquo;
+ </p>
+ <p>
+ This was too much for the bully. He knew that Tom would have a clear case
+ against him, and he did not dare answer. Instead he shuffled over to where
+ his wheel lay, picked it up, and rode slowly off.
+ </p>
+ <p>
+ &ldquo;Good riddance,&rdquo; murmured Tom. He looked about, and saw that he was near a
+ house, in the rear of which was a good-sized barn. &ldquo;Guess I'll ask if I
+ can leave the Butterfly there,&rdquo; he murmured, and, ringing the doorbell, he
+ was greeted by a man.
+ </p>
+ <p>
+ &ldquo;I'll pay you if you'll let me store my machine in the barn a little
+ while, until I go into the city, and return,&rdquo; spoke the lad.
+ </p>
+ <p>
+ &ldquo;Indeed, you're welcome to leave it there without pay,&rdquo; was the answer.
+ &ldquo;I'm interested in airships, and, I'll consider it a favor if you'll let
+ me look yours over while it's here.&rdquo;
+ </p>
+ <p>
+ Tom readily agreed, and a few minutes later he had caught a trolley going
+ into the city. He was soon in one of the largest jewelry stores of
+ Chester.
+ </p>
+ <p>
+ &ldquo;I'd like to get an expert opinion as to whether or not those stones are
+ diamonds,&rdquo; spoke Tom, to the polite clerk who came up to wait on him, and
+ our hero handed over the two gems which Mr. Jenks had given him. &ldquo;I'm
+ willing to pay for the appraisement, of course,&rdquo; the young inventor added,
+ as he saw the clerk looking rather doubtfully at him, for Tom had on a
+ rough suit, which he always donned when he flew in his monoplane.
+ </p>
+ <p>
+ &ldquo;I'll turn them over to our Mr. Porter, a gem expert,&rdquo; said the clerk.
+ &ldquo;Please be seated.&rdquo;
+ </p>
+ <p>
+ The young man disappeared into a private office with the stones, and Tom
+ waited. He wondered if he was going to have his trouble for his pains.
+ Presently two elderly gentlemen came from the little room, on the glass
+ door of which appeared the word &ldquo;Diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;Who brought these stones in?&rdquo; asked one of the men, evidently the
+ proprietor, from the deference paid him by the clerk. The latter motioned
+ to Tom.
+ </p>
+ <p>
+ &ldquo;Will you kindly step inside here?&rdquo; requested the elderly man. When the
+ door was closed, Tom found himself in a room which was mostly taken up
+ with a bench for the display of precious stones, a few chairs, and some
+ lights arranged peculiarly; while various scales and instruments stood on
+ a table.
+ </p>
+ <p>
+ &ldquo;You wished an opinion on&mdash;on these?&rdquo; queried the proprietor of the
+ place. Tom noticed at once that the word &ldquo;diamonds&rdquo; was not used.
+ </p>
+ <p>
+ &ldquo;I wanted to find out if they were of any value,&rdquo; he said. &ldquo;Are they
+ diamonds?&rdquo;
+ </p>
+ <p>
+ &ldquo;Would you mind stating where you got them?&rdquo; asked the other of the two
+ men.
+ </p>
+ <p>
+ &ldquo;Is that necessary?&rdquo; inquired the lad. &ldquo;I came by them in a legitimate
+ manner, if that's what you mean, and I can satisfy you on that point. I am
+ willing to pay for any information you may give me as to their value.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, it isn't that,&rdquo; the proprietor hastened to assure him. &ldquo;But these are
+ diamonds of such a peculiar kind, so perfect and without a flaw, that I
+ wondered from what part of the world they came.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then they are diamonds?&rdquo; asked Tom, eagerly.
+ </p>
+ <p>
+ &ldquo;The finest I have ever tested!&rdquo; declared the other man, evidently Mr.
+ Porter, the gem expert. &ldquo;They are a joy to look at, Mr. Roberts,&rdquo; he went
+ on, turning to the proprietor. &ldquo;If it is possible to get a supply of them
+ you would be justified in asking half as much again as we charge for
+ African or Indian diamonds. The Kimberly products are not to be compared
+ to these,&rdquo; and he looked at the two stones in his hand&mdash;the one cut,
+ and sparkling brilliantly, the other in a rough state.
+ </p>
+ <p>
+ &ldquo;Do you care to state where these diamonds came from?&rdquo; asked Mr. Roberts,
+ looking critically at Tom.
+ </p>
+ <p>
+ &ldquo;I had rather not,&rdquo; answered the lad. &ldquo;It is enough for me to know that
+ they are diamonds. How much is your charge?&rdquo;
+ </p>
+ <p>
+ &ldquo;Nothing,&rdquo; was the unexpected answer. &ldquo;We are very glad to have had the
+ opportunity of seeing such stones. Is there any chance of getting any
+ more?&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps,&rdquo; answered Tom, as he accepted the gems which the expert held out
+ to him.
+ </p>
+ <p>
+ &ldquo;Then might we speak for a supply?&rdquo; went on Mr. Roberts, eagerly. &ldquo;We will
+ pay you the full market price.&rdquo;
+ </p>
+ <p>
+ &ldquo;What is the value of these stones?&rdquo; asked Tom.
+ </p>
+ <p>
+ Mr. Roberts looked at his gem expert.
+ </p>
+ <p>
+ &ldquo;It is difficult to say,&rdquo; was the answer of the man who had handed Tom the
+ gems. &ldquo;They are so far superior to the usual run of diamonds, that I feel
+ justified in saying that the cut one would bring fifteen hundred dollars,
+ anywhere. In fact, I would offer that for it. The other is larger, though
+ what it would lose in cutting would be hard to say. I should say it was
+ worth two thousand dollars as it is now.&rdquo;
+ </p>
+ <p>
+ &ldquo;Thirty-five hundred dollars for these two stones!&rdquo; exclaimed Tom.
+ </p>
+ <p>
+ &ldquo;They are worth every cent of it,&rdquo; declared Mr. Roberts. &ldquo;Do you want to
+ sell?&rdquo;
+ </p>
+ <p>
+ Tom shook his head. He could scarcely believe the good news. Mr. Jenks had
+ told the truth. Now the young inventor could go with him to seek the
+ diamond makers.
+ </p>
+ <p>
+ &ldquo;Can you get any more of these?&rdquo; went on Mr. Roberts.
+ </p>
+ <p>
+ &ldquo;I think so&mdash;that is I don't know&mdash;I am going to try,&rdquo; answered
+ the lad.
+ </p>
+ <p>
+ &ldquo;Then if you succeed I wish you would sell us some,&rdquo; fairly begged the
+ proprietor of the store.
+ </p>
+ <p>
+ &ldquo;I will,&rdquo; promised Tom, but he little knew what lay before him, or perhaps
+ he would not have made that promise. He thanked the diamond merchant for
+ his kindness, and arranged to have the cut stone set in a pin for Miss
+ Nestor. The uncut gem Tom took away with him.
+ </p>
+ <p>
+ Thinking of many things, and wondering how best to start in his airship
+ Red Cloud for the mysterious Phantom Mountain, Tom hurried back to where
+ he had left the monoplane, wheeled it out, and was soon soaring through
+ the air toward Shopton.
+ </p>
+ <p>
+ &ldquo;I think I'll go with Mr. Jenks,&rdquo; he decided, as he prepared for a landing
+ in the open space near his aeroplane shed. &ldquo;It will be a risky trip,
+ perhaps, but I've taken risks before. When Mr. Jenks comes to-night I'll
+ tell him I'll help him to get his rights, and discover the secret of the
+ diamond makers.&rdquo;
+ </p>
+ <p>
+ As Tom was wheeling the Butterfly into the shed, Eradicate came out to
+ help him.
+ </p>
+ <p>
+ &ldquo;Dere's a gen'man here to see yo', Massa Tom,&rdquo; said the colored man.
+ </p>
+ <p>
+ &ldquo;Who is it?&rdquo;
+ </p>
+ <p>
+ &ldquo;I dunno. He keep askin' ef yo' de lad what done bust up Earthquake
+ Island, an' send lightnin' flashes up to de sky, an' all sech questions
+ laik dat.&rdquo;
+ </p>
+ <p>
+ &ldquo;It isn't Mr. Damon; is it, Rad? He hasn't been around in some time.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, Massa Tom, it ain't him. I knows dat blessin' man good an' proper. I
+ jest wish he'd bless mah mule Boomerang some day, an' take some oh de
+ temper out ob him. No, sah, it ain't Massa Damon. De gen'man's in de
+ airship shed waitin' fo' you.&rdquo;
+ </p>
+ <p>
+ &ldquo;In the airship shed! No strangers are allowed in there, Rad.&rdquo;
+ </p>
+ <p>
+ &ldquo;I knows it, Massa Tom, but he done persisted his se'f inter it, an' he
+ wouldn't come out when I told him; an' your pa an' Mr. Jackson ain't
+ home.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll see about this,&rdquo; exclaimed Tom, striding to the large shed, where
+ the Red Cloud was kept. As he entered it he saw a man looking over the
+ wonderful craft.
+ </p>
+ <p>
+ &ldquo;Did you want to see me?&rdquo; asked Tom, sharply, for he did not like
+ strangers prowling around.
+ </p>
+ <p>
+ &ldquo;I did, and I apologize for entering here, but I am interested in
+ airships, and I thought you might want to hire a pilot. I am in need of
+ employment, and I have had considerable to do with balloons and
+ aeroplanes, but never with an airship like this, which combines the two
+ features. Do you wish to hire any one.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, I don't!&rdquo; replied Tom, sharply, for he did not like the looks of the
+ man.
+ </p>
+ <p>
+ &ldquo;I was told that you did,&rdquo; was the rather surprising answer.
+ </p>
+ <p>
+ &ldquo;Who told you?&rdquo;
+ </p>
+ <p>
+ The man looked all around the shed, before replying, as if fearful of
+ being overheard. Then, stepping close to Tom, he whispered:
+ </p>
+ <p>
+ &ldquo;Mr. Jenks told me!&rdquo;
+ </p>
+ <p>
+ &ldquo;Mr. Jenks?&rdquo; Tom could not conceal his astonishment.
+ </p>
+ <p>
+ &ldquo;Yes. Mr. Barcoe Jenks. But I did not come here to merely ask you for
+ employment. I would like to hire out to you, but the real object of my
+ visit was to say this to you.&rdquo;
+ </p>
+ <p>
+ The man approached still closer to Tom, and, in a lower voice, and one
+ that could scarcely be heard, he fairly hissed:
+ </p>
+ <p>
+ &ldquo;Don't go with Barcoe Jenks to seek the diamond makers!&rdquo;
+ </p>
+ <p>
+ Then, before Tom could put out a hand to detain him, had the lad so
+ wished, the man turned suddenly, and fairly ran from the shed.

+ <h2>
+ CHAPTER VI&mdash;MR. DAMON IS ON HAND
+ </h2>
+ <p>
+ The young inventor stood almost spellbound for a few moments. Then
+ recovering himself he made a dash for the door through which the
+ mysterious man had disappeared. Tom saw him sprinting down the road, and
+ was half-minded to take after him, but a cooler thought warned him that he
+ had better not.
+ </p>
+ <p>
+ &ldquo;He may be one of those men who are on Mr. Jenks' trail,&rdquo; reasoned Tom, in
+ which case it might not be altogether safe to attempt to stop him, and
+ make him explain. Or he may be a lunatic, and in that case it wouldn't be
+ altogether healthy to interfere with him.
+ </p>
+ <p>
+ &ldquo;I'll just let him go, and tell Mr. Jenks about him when he comes
+ to-night. But I must warn Rad never to let him in here again. He might
+ damage the airship.&rdquo;
+ </p>
+ <p>
+ Calling to the colored man, Tom pointed to the stranger, who was almost
+ out of sight down the road, and said earnestly:
+ </p>
+ <p>
+ &ldquo;Rad, do you see that fellow?&rdquo;
+ </p>
+ <p>
+ &ldquo;I sho do, Massa Tom, but I sorter has t' strain my eyes t' do it. He's
+ goin' laik my mule Boomerang does when he's comm' home t' dinnah.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's right, Rad. Well, never let that man set foot inside our fence
+ again! If he comes, and I'm home, call me. If I'm away, call dad or Mr.
+ Jackson, and if you're here alone, drive him away, somehow.&rdquo;
+ </p>
+ <p>
+ &ldquo;I will, Massa Tom!&rdquo; exclaimed the colored man, earnestly, &ldquo;an' if I can't
+ do it alone, I'll get Boomerang t' help. Once let dat ar' mule git his
+ heels on a pusson, an' dat pusson ain't goin' t' come bodderin' around any
+ mo'&mdash;that is, not right away.&rdquo;
+ </p>
+ <p>
+ &ldquo;I believe you, Rad. Well, keep a lookout for him, and don't let him in,&rdquo;
+ and with that Tom entered the house to think over matters. They were
+ beginning to assume an aspect he did not altogether like. Not that Tom was
+ afraid of danger, but he preferred to meet it in the open, and the
+ warning, or threat, of the mysterious man disquieted him.
+ </p>
+ <p>
+ When Mr. Swift came home, a little later, his son told him of the midnight
+ interview with Mr. Jenks, for, up to this time, the aged inventor was
+ unaware of it, and Tom also gave an account of the diamonds, speaking of
+ their value.
+ </p>
+ <p>
+ &ldquo;And do you propose to go to Phantom Mountain, in search of the makers of
+ these gems, Tom?&rdquo; asked Mr. Swift.
+ </p>
+ <p>
+ &ldquo;I had about decided to do so, dad.&rdquo;
+ </p>
+ <p>
+ &ldquo;And you're going in the Red Cloud?'
+ </p>
+ <p>
+ &ldquo;Yes.&rdquo;
+ </p>
+ <p>
+ &ldquo;Who are going with you?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, Mr. Jenks will go, of course, and I've no doubt but that if I
+ mention the prospective trip to Mr. Damon, that he'll bless his skating
+ cap, or something like that, and come along.&rdquo;
+ </p>
+ <p>
+ &ldquo;I suppose so, Tom, and I'd like to have you take him. But I think you'll
+ need some one else.&rdquo;
+ </p>
+ <p>
+ &ldquo;Because, from what you have told me, you are going out to a dangerous
+ part of the country, and you may have to deal with unscrupulous men. Three
+ of you are hardly enough to cope with them. You ought to have at least
+ another member of your party. If I was not busy on my invention of a new
+ wireless motor I would go along, but I can't leave. You might take Mr.
+ Jackson.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, you need him here to help you, dad.&rdquo;
+ </p>
+ <p>
+ &ldquo;How about Eradicate?&rdquo;
+ </p>
+ <p>
+ Tom smiled.
+ </p>
+ <p>
+ &ldquo;Rad would get homesick for his mule Boomerang, and I'd have to bring him
+ back just when we'd found the diamonds,&rdquo; replied the young inventor. &ldquo;No,
+ we'll have to think of some one else. I'll ask Mr. Damon, and then I'll
+ consider matters further. I expect to see Mr. Jenks to-night, and he may
+ have some one in mind.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps that will be a good plan. Well, Tom, I trust you will take good
+ care of yourself, and not run into unnecessary danger. Is the Red Cloud in
+ good shape for the voyage?&rdquo;
+ </p>
+ <p>
+ &ldquo;It needs looking over. I'm going to get right at it.&rdquo;
+ </p>
+ <p>
+ &ldquo;It's a pretty indefinite sort of a quest you're going on, Tom, my son.
+ How do you expect to find Phantom Mountain?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it's going to be quite a task. In the first place we'll head for
+ Leadville, Colorado, and then we'll go to Indian Ridge and make some
+ inquiries. We may get on the track of the place that way. If we don't, why
+ I'll take the airship up as high as is necessary and sort of prospect
+ until we see that big cliff that's shaped like a head. That will give us
+ something to go by.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, do the best you can. If you can discover the secret of making
+ diamonds it will be a valuable one.&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess it will, dad; and Mr. Jenks is entitled to know it, for he paid
+ his good money to that end. He has promised to go halves with me, as
+ payment for the use of the airship, and I must say the two diamonds he
+ gave me last night have proved very valuable.&rdquo;
+ </p>
+ <p>
+ &ldquo;Two diamonds, Tom? You only showed me one, an uncut gem;&rdquo; and Mr. Swift
+ looked at his son.
+ </p>
+ <p>
+ &ldquo;Oh, the other&mdash;er&mdash;the other is&mdash;I left it with a
+ jeweler,&rdquo; and Tom blushed a trifle, as he thought of the present he
+ contemplated making to Mary Nestor.
+ </p>
+ <p>
+ That afternoon, as Tom was out in the shed of the Red Cloud looking over
+ the airship, to see what would be necessary to do to it in order to get it
+ in shape for a long trip, he heard voices outside.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;yes, I know the way in perfectly well,&rdquo; he caught. &ldquo;You needn't
+ bother to come, my good fellow. Just step this way, and I'll show you
+ something worth seeing.&rdquo;
+ </p>
+ <p>
+ &ldquo;I wonder if it's that mysterious man coming back?&rdquo; thought Tom. He
+ dropped the tool he was using, and hurried to the door. As he approached
+ it he heard the voice continue.
+ </p>
+ <p>
+ &ldquo;Why bless my shoe laces, Mr. Parker! You'll see a wonderful airship, I
+ promise you. Wonderful! Bless my hatband, but I hope Tom is here!&rdquo;
+ </p>
+ <p>
+ &ldquo;Mr. Damon!&rdquo; exclaimed our hero, as he recognized the tones of his
+ eccentric friend. &ldquo;But who is with him?&rdquo;
+ </p>
+ <p>
+ A moment later he caught sight of the gentleman who was always blessing
+ himself, or something. Behind him stood another man, whose features Tom
+ could not see plainly.
+ </p>
+ <p>
+ &ldquo;Hello, Tom Swift!&rdquo; called Mr. Damon. &ldquo;Looking over the Red Cloud, eh?
+ Does that mean you're off on another trip?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess it does,&rdquo; answered the lad.
+ </p>
+ <p>
+ &ldquo;Where to this time? if I may ask.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm thinking of going off to the mountains to find a band of men engaged
+ in making diamonds,&rdquo; replied Tom.
+ </p>
+ <p>
+ &ldquo;Making diamonds! Bless my finger ring! Making diamonds! A trip to the
+ mountains! Bless my disposition! but do you know I'd like to go with you!&rdquo;
+ </p>
+ <p>
+ &ldquo;I was thinking of asking you, Mr. Damon.&rdquo;
+ </p>
+ <p>
+ &ldquo;Were you? Bless my heart, I'm glad you thought of me. You don't by any
+ possible chance want another person; do you?&rdquo;
+ </p>
+ <p>
+ &ldquo;We were thinking of having four in the party, Mr. Damon,&rdquo; and Tom
+ wondered who was with his eccentric friend.
+ </p>
+ <p>
+ &ldquo;Then bless my election ticket! This is the very chance for you, Mr.
+ Parker!&rdquo; cried Mr. Damon. &ldquo;Will you go with us? It will be just what you
+ need,&rdquo; and Mr. Damon stepped aside, revealing to Tom the features of Mr.
+ Ralph Parker, the scientist who had correctly predicted the destruction of
+ Earthquake Island.

+ <h2>
+ CHAPTER VII&mdash;MR. PARKER PREDICTS
+ </h2>
+ <p>
+ Tom Swift was a most generous lad, but when he saw that Mr. Damon had with
+ him Mr. Parker, the gloomy scientist, who seemed to take delight in
+ predicting disasters, our hero's spirits were not exactly of the best. He
+ would have much preferred not to take Mr. Parker on the quest for the
+ diamond makers, but, since Mr. Damon had mentioned it, he did not see how
+ he could very well refuse.
+ </p>
+ <p>
+ &ldquo;But perhaps he won't care to go,&rdquo; thought Tom.
+ </p>
+ <p>
+ He was undeceived a moment later, however, for the scientist remarked:
+ </p>
+ <p>
+ I am very glad to meet you once more, Mr. Swift. I have scarcely thanked
+ you enough for what you did for us in erecting your wireless station on
+ Earthquake Island, which, as you recall, I predicted would sink into the
+ sea. It did, I am glad to say, not because I like to see islands
+ destroyed, but because science has been vindicated. Now I have just heard
+ you remark that you are about to set off to the mountains in search of
+ some men who are making diamonds. I need hardly state that this is utterly
+ useless, for no diamonds, commercially valuable, can be made by men. But
+ the trip may be valuable in that it will permit me to demonstrate some
+ scientific facts.
+ </p>
+ <p>
+ &ldquo;Therefore, if you will permit me, I will be very glad to accompany you
+ and Mr. Damon. I shall be delighted, in short, and I can start as soon as
+ you are ready.&rdquo;
+ </p>
+ <p>
+ &ldquo;There's no hope for it!&rdquo; thought Tom, dismally. &ldquo;I suppose he'll wake up
+ every morning, and predict that before night the world will come to an
+ end, or he'll prophesy that the airship will blow up, and vanish, when
+ about seven miles above the clouds. Well, there's no way out of it, so
+ here goes.&rdquo;
+ </p>
+ <p>
+ Thereupon Tom welcomed the scientist as cordially as he could, and invited
+ him to form one of the party that would set off in the airship to search
+ for Phantom Mountain.
+ </p>
+ <p>
+ &ldquo;Bless my jewelry box!&rdquo; exclaimed Mr. Damon, when this formality was over.
+ &ldquo;Tell me more about it, Tom.&rdquo;
+ </p>
+ <p>
+ Which our hero did, stating the need of maintaining secrecy on account of
+ the danger to Mr. Jenks. Mr. Damon and Mr. Parker both agreed to say
+ nothing about the matter, and then the scientist became much interested in
+ the Red Cloud, which he closely examined. He even complimented Tom on the
+ skill shown in making it, and, contrary to our hero's expectation, did not
+ predict that it would blow up the next time it was used.
+ </p>
+ <p>
+ &ldquo;How did you happen to arrive just at this time, Mr. Damon?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;It was partly due to Mr. Parker,&rdquo; was the answer. &ldquo;I had not seen him
+ since we were rescued from the island, until a few days ago he called on
+ me at my home. I happened to mention that you lived near here, and
+ suggested that he might like to see some of your inventions. He agreed,
+ and we came over in my auto. And now, bless my liver-pin! I find you about
+ to start off on another trip.&rdquo;
+ </p>
+ <p>
+ &ldquo;And have you fully decided to go with me?&rdquo; asked Tom. &ldquo;There may be
+ danger, and I don't like the way that mysterious man behaved.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, bless my revolver!&rdquo; cried Mr. Damon. &ldquo;I'm used to danger by this
+ time. Of course I'm going, and so is Mr. Parker. Do you know,&rdquo; and the
+ man, who was always blessing something, came closer to the lad, and
+ whispered: &ldquo;Do you know, Tom, Mr. Parker is a very peculiar individual.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm sure of it,&rdquo; answered the young inventor, looking at the gentleman in
+ question, who was then inside the airship cabin.
+ </p>
+ <p>
+ &ldquo;But he's all right, even if he is predicting unpleasant things,&rdquo; went on
+ Mr. Damon. &ldquo;I think we'll get better acquainted with him after a bit.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope so,&rdquo; agreed Tom, but he did not realize then how close his
+ companionship with Mr. Parker was to be, nor what dangers they were to
+ share later.
+ </p>
+ <p>
+ The friends talked at considerable length of the prospective trip, and
+ Tom, by this time, had ascertained what needed to be done to the airship
+ to get it in shape to travel. It would take about a week, and, in the
+ meanwhile, Mr. Damon would go home and get his affairs in order for the
+ voyage. Tom's father was introduced to Mr. Parker, and, the former,
+ finding that the scientist held some views in common with him, invited the
+ gloomy predictor to remain at the Swift home until the Red Cloud was ready
+ to sail. Tom could not repress a groan at this, but he decided he would
+ have to make the best of it.
+ </p>
+ <p>
+ Mr. Damon left for home that afternoon, promising to be on hand at the
+ time set to start for Phantom Mountain.
+ </p>
+ <p>
+ Tom was up waiting for Mr. Jenks at twelve o'clock that night. Shortly
+ after the hour he saw a dark figure steal into the orchard. At first he
+ feared lest it might be one of the spies who were, he was now convinced,
+ on the trail of the man who was seeking to discover the secret of the
+ diamond makers. But a whistle, which came to the lad's ear a moment later
+ (that being a signal Mr. Jenks had agreed to sound), told Tom that it was
+ none other than the visitor he expected.
+ </p>
+ <p>
+ &ldquo;All right, Mr. Jenks, I'm here,&rdquo; called Tom, cautiously. &ldquo;Come over this
+ way,&rdquo; and he went out from the shadow of the house, where he had been
+ waiting, and met the men. &ldquo;We'll go into my private work-shop,&rdquo; the youth
+ added, leading the way.
+ </p>
+ <p>
+ &ldquo;Have you decided to go with me?&rdquo; asked Mr. Jenks, in an anxious whisper.
+ &ldquo;Did you find the diamonds to be real ones?&rdquo;
+ </p>
+ <p>
+ &ldquo;I did; and I'm going,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;Good! That relieves my mind. But we are still in danger. I was followed
+ by my shadower to-day, and only succeeded in shaking him off just before
+ coming here. I don't believe he knows what I am about to do.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, yes he does,&rdquo; said Tom.
+ </p>
+ <p>
+ &ldquo;He does? How?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because he was here, and warned me against you!&rdquo;
+ </p>
+ <p>
+ &ldquo;You don't mean it! Well, they are getting desperate! We must be on our
+ guard. What sort of a man was he?&rdquo;
+ </p>
+ <p>
+ Tom described the fellow, and Mr. Jenks stated that this tallied with the
+ appearance of the person who had been shadowing him.
+ </p>
+ <p>
+ &ldquo;But we'll fool them yet!&rdquo; cried Tom, who had now fully entered into the
+ spirit of the affair. &ldquo;If they can follow us in the Red Cloud they're
+ welcome to. I think we'll get ahead of them.&rdquo;
+ </p>
+ <p>
+ He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed that it
+ would add to the strength of the party to take these two gentlemen along.
+ </p>
+ <p>
+ &ldquo;Though I can't say I care so much for Mr. Parker,&rdquo; he added. &ldquo;But now as
+ to ways and means. When can we start?&rdquo;
+ </p>
+ <p>
+ Thereupon he and Tom talked over details in the seclusion of the little
+ office, and arranged to leave Shopton in about a week. In the meanwhile
+ the airship would be overhauled, stocked with supplies and provisions, and
+ be made ready for a swift dash to the mountains.
+ </p>
+ <p>
+ &ldquo;And now I must be going,&rdquo; said Mr. Jenks. &ldquo;I have a great deal to do
+ before I can start on this trip, and I hope I am not prevented by any of
+ those men who seem to be trailing me.&rdquo;
+ </p>
+ <p>
+ &ldquo;How could they prevent you?&rdquo; Tom wanted to know.
+ </p>
+ <p>
+ &ldquo;Oh, there are any number of ways,&rdquo; was the answer. &ldquo;But I'm glad you
+ found that my diamonds were real. We'll soon have plenty, if all goes
+ well.&rdquo;
+ </p>
+ <p>
+ As Mr. Jenks left the shop, he started back, in some alarm.
+ </p>
+ <p>
+ &ldquo;What's the matter?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Over there&mdash;I thought I saw a figure sneaking along under the trees&mdash;that
+ man&mdash;perhaps&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;That's Eradicate, our colored helper,&rdquo; replied Tom, with a laugh. &ldquo;I
+ posted him there to see that no strangers came into the orchard.
+ Everything all right, Rad?&rdquo; he asked, raising his voice.
+ </p>
+ <p>
+ &ldquo;Yais, sah, Massa Tom. Nobody been around yeah this night.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's good. You can go to bed now,&rdquo; and Eradicate, yawning loudly, went
+ to his shack. A little later Tom sought his own room, Mr. Jenks having
+ hurried off to town, where he was boarding.
+ </p>
+ <p>
+ The next few days saw Tom busily engaged on the airship, making some
+ changes and a few repairs that were needed. His father, Eradicate and Mr.
+ Jackson helped him. As for Mr. Parker, the scientist, he went about the
+ place, being much interested in the various machines which Tom or Mr.
+ Swift had patented.
+ </p>
+ <p>
+ At other times the scientist would stroll about the extensive grounds,
+ making what he said were &ldquo;observations.&rdquo; One afternoon Tom saw him,
+ apparently much excited, kneeling down back of a shed, with his ear to the
+ ground.
+ </p>
+ <p>
+ &ldquo;What is the matter?&rdquo; asked the lad, thinking perhaps Mr. Parker might be
+ ill.
+ </p>
+ <p>
+ &ldquo;Have you ever had any earthquakes here, Tom Swift?&rdquo; asked the scientist,
+ quietly.
+ </p>
+ <p>
+ &ldquo;Earthquakes? No. We had enough of them on the island.&rdquo;
+ </p>
+ <p>
+ &ldquo;And you are going to have one here, in about two minutes!&rdquo; cried Mr.
+ Parker. &ldquo;I predict that this place will be shaken by a tremendous shock
+ very soon. We had all better get away from the vicinity of buildings.&rdquo;
+ </p>
+ <p>
+ &ldquo;What makes you think there will be an earthquake?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Because I can hear the rumbling beneath the ground at this very minute.
+ It is increasing in volume, showing that the tremors are working this way.
+ There will soon be a great subterranean upheaval! Listen for yourself.&rdquo;
+ </p>
+ <p>
+ Tom cast himself down on the grass. Placing his ear close to the ground he
+ did hear a series of dull thuds. He arose, not a little alarmed. There had
+ never been any earthquakes in Shopton, yet he had great respect for Mr.
+ Parker's scientific attainments.
+ </p>
+ <p>
+ Just then Eradicate Sampson came along. He saw Tom and Mr. Parker lying
+ flat on the ground, and surprise showed on his honest, black face.
+ </p>
+ <p>
+ &ldquo;Fo' de land sakes!&rdquo; cried Eradicate. &ldquo;What am de mattah now, Massa Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Earthquake coming,&rdquo; answered Tom, briefly. &ldquo;Better get away from the
+ buildings, Rad. They might fall!&rdquo; Tom's face showed the alarm he felt.
+ What would happen to all of his valuable machines&mdash;to the Red Cloud?
+ </p>
+ <p>
+ &ldquo;Earthquake?&rdquo; murmured Eradicate, and he, too, cast himself down to
+ listen. A moment later he arose with a laugh.
+ </p>
+ <p>
+ &ldquo;What's the matter?&rdquo; cried Tom.
+ </p>
+ <p>
+ &ldquo;Why, dat ain't no earthquake!&rdquo; declared the colored man.
+ </p>
+ <p>
+ &ldquo;No. Then perhaps you know what it is,&rdquo; said Mr. Parker, somewhat sharply.
+ </p>
+ <p>
+ &ldquo;Course I knows what it am,&rdquo; answered Eradicate, with dignity. &ldquo;Dat noise
+ am my mule Boomerang, kickin' in his stable, on account oh me not feedin'
+ him yet. Dat's what it am. I'se gwine right now t' gib him his oats, and
+ den yo' see dat de noise stop. Boomerang allers kick dat way when he's
+ hungry. I show yo'!&rdquo;
+ </p>
+ <p>
+ And, sure enough, when Eradicate had gone to the mule's stable, which was
+ near where Mr. Parker had heard the mysterious sounds, they immediately
+ ceased.
+ </p>
+ <p>
+ &ldquo;Dat mule was all de earthquake dere was around here,&rdquo; said the colored
+ man as he came out.
+ </p>
+ <p>
+ Mr. Parker walked away, saying nothing, and Tom did not make any comments&mdash;just
+ then.

+ <h2>
+ CHAPTER VIII&mdash;OFF FOR THE WEST
+ </h2>
+ <p>
+ It was a great relief to Tom, to find that there was no danger from an
+ earth tremor. Now that he had made up his mind to go in search of the
+ diamond makers, he wanted nothing to interfere with it. Lest the feelings
+ of Mr. Parker might be hurt by the mistake he had made, the young inventor
+ cautioned Eradicate not to say anything more about the matter.
+ </p>
+ <p>
+ &ldquo;'Deed an' I won't,&rdquo; the colored man promised. &ldquo;I'se only too glad dere
+ wa'n't no earthquake, dat's what I is.&rdquo;
+ </p>
+ <p>
+ As for Mr. Parker, he did not appear much put out by his error in
+ predicting.
+ </p>
+ <p>
+ &ldquo;I am sure that what I heard was a tremor, due to some distant earthquake
+ shock,&rdquo; he said. &ldquo;The mule's kicking was only a coincidence.&rdquo;
+ </p>
+ <p>
+ And Tom let him have his way about it. The week was drawing to a close,
+ and the Red Cloud was nearly in shape for the voyage. At almost the last
+ minute Tom found that he needed some electrical apparatus for the airship,
+ and as he had to go to Chester for it, he decided he would make the trip
+ in his monoplane, and, while in the city, would also get the diamond pin
+ he was having made for Mary Nestor.
+ </p>
+ <p>
+ He started off early one morning, in the swift little craft Butterfly, and
+ soon had reached Chester. The diamond brooch was ready for him.
+ </p>
+ <p>
+ &ldquo;It is one of the most beautiful stones we have ever set,&rdquo; the diamond
+ merchant told him. &ldquo;Don't forget, if you find any more, Mr. Swift, to let
+ us have a chance to bid on them.&rdquo;
+ </p>
+ <p>
+ &ldquo;I may,&rdquo; Tom promised, rather indefinitely. Then, having purchased his
+ electrical supplies, he made a quick trip to Shopton, stopping on the way
+ to call on Miss Nestor.
+ </p>
+ <p>
+ &ldquo;Why Tom, I'm delighted to see you!&rdquo; cried the girl, blushing prettily.
+ &ldquo;Did you come for some apple turnovers?&rdquo; and she laughed, as she referred
+ to a call Tom had once paid, when a new cook had been engaged, and when
+ the pastry formed a feature of the meal.
+ </p>
+ <p>
+ &ldquo;No turnovers this time,&rdquo; said the young inventor. &ldquo;I came to wish you
+ many happy returns of the day.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, you remembered my birthday! How nice of you!&rdquo;
+ </p>
+ <p>
+ &ldquo;And here is something else,&rdquo; added our hero, rather awkwardly, as he
+ handed her the diamond pin.
+ </p>
+ <p>
+ &ldquo;Oh, Tom! This for me! Oh, it's too lovely&mdash;it's far too much!&rdquo;
+ </p>
+ <p>
+ &ldquo;It isn't half enough!&rdquo; he declared, warmly.
+ </p>
+ <p>
+ &ldquo;Oh, what a large diamond!&rdquo; Mary cried as she saw the sparkling stone. &ldquo;I
+ never saw one so large and beautiful!&rdquo;
+ </p>
+ <p>
+ &ldquo;It's just as easy to make them large as small,&rdquo; explained Tom.
+ </p>
+ <p>
+ &ldquo;Make them?&rdquo; she looked the surprise she felt.
+ </p>
+ <p>
+ &ldquo;Yes, I'm about to start for the place where diamonds are made.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, Tom! But isn't it dangerous? I mean won't you have to go to some far
+ country&mdash;like Africa&mdash;to get to where diamonds are made?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, we are going on quite a trip, but not as far as that. And as for
+ the danger&mdash;well, we'll have to take what comes,&rdquo; and he told her
+ something of the proposed quest.
+ </p>
+ <p>
+ &ldquo;Oh, it sounds&mdash;sounds scary!&rdquo; Mary exclaimed, when she had heard of
+ Mr. Jenks' experience. &ldquo;Do be careful, Tom!&rdquo;
+ </p>
+ <p>
+ &ldquo;I will,&rdquo; he promised, and, somehow he was glad that she had cautioned him
+ thus&mdash;and in such tones as she had used. For Mary Nestor was a girl
+ that any young chap would have been glad to have manifest an interest in
+ him.
+ </p>
+ <p>
+ &ldquo;Well, I guess I'll have to say good-by,&rdquo; spoke Tom, at length. &ldquo;We expect
+ to start in a couple of days, and I may not get another chance to see
+ you.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I&mdash;I hope you come back safely,&rdquo; faltered Mary, and then she
+ held out her hand, and Tom&mdash;well, it's none of our affair what Tom
+ did after that, except to say that he hurried out, fairly jumped into his
+ monoplane, and completed the trip home.
+ </p>
+ <p>
+ As the Red Cloud has been fully described in the volume entitled &ldquo;Tom
+ Swift and His Airship,&rdquo; we will not go into details about it now.
+ Sufficient to say that it was a combination of a biplane and dirigible
+ balloon. It could be used either as one or the other, and the gas-bag
+ feature was of value when the wind was too great to allow the use of the
+ planes, or when the motive power, for some reason stopped. In that event
+ the airship could remain suspended far above the clouds if necessary.
+ There was provision for manufacturing the gas on board.
+ </p>
+ <p>
+ The Red Cloud was fitted up to accommodate about ten persons, though it
+ was seldom that this number was carried. Two persons could successfully
+ operate the machinery. There were sleeping berths, and in the main cabin a
+ sitting-room, a dining-room, and a kitchen. There was also the motor
+ compartment, and a steering tower, from which the engines could be
+ controlled.
+ </p>
+ <p>
+ It was in this craft that the seekers after the diamond makers proposed
+ undertaking the trip. Mr. Damon came on from his home in Waterfield about
+ two days before the date set to leave, and Mr. Jenks, had, three days
+ before this, taken up his abode at the Swift home. Mr. Parker, as has been
+ stated, was already there, and he had put in his time making a number of
+ scientific observations, though he had made no more predictions.
+ </p>
+ <p>
+ Nothing more had been seen of the mysterious man who had warned Tom, and
+ the young inventor and Mr. Jenks began to hope that they had thrown their
+ enemies off the track.
+ </p>
+ <p>
+ &ldquo;Though I don't imagine they'll give up altogether,&rdquo; said Mr. Jenks.
+ &ldquo;They're too desperate for that. We'll have trouble with them yet.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it can't be helped,&rdquo; decided Tom. &ldquo;We'll try and be ready for it,
+ when it comes,&rdquo; and then, dismissing the matter from his mind, he busied
+ himself about the airship.
+ </p>
+ <p>
+ The food and supplies had all been put aboard, and they expected to start
+ the next morning. In order to make sure that any stones which they might
+ succeed in getting from the diamond makers were real gems, a set of
+ testing apparatus was taken along. Mr. Parker had had some experience in
+ this line, and, in spite of the fact that he might make direful
+ predictions, Tom was rather glad, after all, that the scientist was going
+ to accompany them.
+ </p>
+ <p>
+ &ldquo;But what is worrying me,&rdquo; said Mr. Damon, &ldquo;is what we are going to do
+ after we get to Phantom Mountain. What are your plans, Mr. Jenks? Will you
+ go in, and demand your share of the diamond-making business?&rdquo;
+ </p>
+ <p>
+ &ldquo;I have a right to it, as I invested a large sum in it, and I am entitled
+ to more than a half-share. But, of course, I can't say what I'll do until
+ I get there. We may have to act very secretly.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm inclined to think we will,&rdquo; said Tom. &ldquo;My plan would be to gain
+ access to the cave, if possible, and watch them at work. We might be able
+ to discover the secret of making diamonds, and, after all, that's what you
+ want, isn't it, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, I paid my money for the secret, and I ought to have it. If I can get
+ it quietly, so much the better. If not, I'll fight for my rights!&rdquo; and he
+ looked very determined.
+ </p>
+ <p>
+ &ldquo;Bless my powder horn!&rdquo; cried Mr. Damon. &ldquo;That's the way to talk! And so
+ we're to go cruising about in the air, looking for a mountain shaped like
+ a man's head.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's it,&rdquo; agreed Mr. Jenks, &ldquo;and when we find it we will be near
+ Phantom Mountain, and the diamond makers.&rdquo;
+ </p>
+ <p>
+ The final details were completed that night. The last of the supplies had
+ been put aboard, the larder was well stocked, the diamond testing
+ apparatus was stored safely away, and all that remained was for the
+ adventurers to board the Red Cloud in the morning, and soar away.
+ </p>
+ <p>
+ That night Tom was uneasy. Several times he got up, and looked toward the
+ shed where the airship was stored. He could not rid himself of the idea
+ that the men to whose interest it was that the diamond-making secret
+ remain undiscovered, might attempt to wreck the airship before the start.
+ Consequently both Eradicate Sampson and Engineer Jackson were on guard.
+ Tom looked from his window, to the shed where the Red Cloud was housed. He
+ saw nothing to cause him any uneasiness.
+ </p>
+ <p>
+ &ldquo;I guess I'm just nervous,&rdquo; he mused. &ldquo;But, all the same, I'll be glad
+ when we've started.&rdquo;
+ </p>
+ <p>
+ They were all up early the next morning, Mr. Damon beginning the day by
+ blessing the sunrise, and many other things that struck his fancy. The
+ airship was wheeled out of the shed, and Tom gave her a final inspection.
+ </p>
+ <p>
+ &ldquo;It's all right,&rdquo; he declared. &ldquo;All aboard!&rdquo;
+ </p>
+ <p>
+ &ldquo;Now, do be careful,&rdquo; begged Mr. Swift. &ldquo;Don't take too many chances,
+ Tom.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll not.&rdquo;
+ </p>
+ <p>
+ The adventurers were in the forward part of the ship, and Tom had taken
+ his place at the wheels and levers in the pilot house. As he was about to
+ start the motor he looked toward the road, and saw a horse and carriage.
+ In the vehicle was a girlish figure, at the sight of which Tom blushed and
+ smiled. He waved his hand.
+ </p>
+ <p>
+ &ldquo;I came to wish you good luck!&rdquo; cried Mary Nestor, for it was she in the
+ carriage.
+ </p>
+ <p>
+ &ldquo;Thanks!&rdquo; cried Tom, leaning from the window of the pilot house. &ldquo;It was
+ good of you to get up so early.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh. I'm always up early,&rdquo; she informed him.
+ </p>
+ <p>
+ &ldquo;Look out that the motor doesn't scare your horse,&rdquo; Tom warned her.
+ </p>
+ <p>
+ &ldquo;Old Dobbin doesn't mind anything,&rdquo; was her answer. &ldquo;I'll see that he
+ doesn't run away with me, as long as you're not on earth to rescue me.
+ Good-by, Tom!&rdquo;
+ </p>
+ <p>
+ &ldquo;Good-by!&rdquo; he called, and then he pulled the lever that set in motion the
+ motor, and whirled the great propellers about. They whizzed around with a
+ roar, and the Red Cloud, shivering and trembling with the vibration, rose
+ in the air like some great bird.
+ </p>
+ <p>
+ &ldquo;We're off for the West and Phantom Mountain!&rdquo; called Tom to his
+ companions.
+ </p>
+ <p>
+ As the airship soared upward, Eradicate Sampson ran forward from where he
+ had been standing near his mule Boomerang. He waved his hands, and shouted
+ something.
+ </p>
+ <p>
+ &ldquo;Bless my hatband! What does he want?&rdquo; asked Mr. Damon, watching him
+ curiously.
+ </p>
+ <p>
+ &ldquo;It sounds as if he were calling to us to come back,&rdquo; spoke Mr. Parker.
+ </p>
+ <p>
+ &ldquo;It's too late now,&rdquo; decided Tom. &ldquo;Maybe he forgot to tell us good-by,&rdquo;
+ but, he felt a vague wonder at Eradicate's odd motions; for the colored
+ man was pointing toward the stern of the airship, as if there was
+ something wrong there. But the Red Cloud soared on.

+ <h2>
+ CHAPTER IX&mdash;A WARNING BY WIRELESS
+ </h2>
+ <p>
+ Rapidly the airship ascended, and, when it was high over the town of
+ Shopton, Tom headed the craft due west. Looking down he tried to descry
+ Mary Nestor, in her carriage, but the trees were in the way, their
+ interlocking branches hiding the girl. Tom did see crowds of other
+ persons, though, thronging the streets of Shopton, for, though the young
+ inventor had made many flights, there was always a novelty about them,
+ that brought out the curious.
+ </p>
+ <p>
+ &ldquo;A good start, Tom Swift,&rdquo; complimented Mr. Parker. &ldquo;Is it always as easy
+ as this?&rdquo;
+ </p>
+ <p>
+ &ldquo;Starting always is,&rdquo; was the answer, &ldquo;though, as the Irishman said,
+ coming down isn't sometimes quite so comfortable.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my gizzard! That's so,&rdquo; cried the eccentric Mr. Damon. &ldquo;Can we
+ vol-plane to earth in the Red Cloud, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, but not as easily as in the Butterfly. However I hope we will not
+ have to. Now, Mr. Damon, if you will just take charge of the steering
+ apparatus for a minute, I want to go aft.&rdquo;
+ </p>
+ <p>
+ &ldquo;What for?&rdquo;
+ </p>
+ <p>
+ &ldquo;I wish to see if everything is all right. I can't imagine why Eradicate
+ was making those queer motions.&rdquo;
+ </p>
+ <p>
+ Mr. Damon, who knew how to operate the Red Cloud, was soon guiding her on
+ the course, while Tom made his way to the rear compartments, through the
+ motor room, where the stores of supplies and food were kept. He made a
+ careful examination, looking from an after window, and even going out on a
+ small, open platform, but could discover nothing wrong.
+ </p>
+ <p>
+ &ldquo;I guess Rad was just capering about without any special object,&rdquo; mused
+ Tom, but it was not long after this that they learned to their dismay,
+ that the colored man had had a method in his madness.
+ </p>
+ <p>
+ On his way back through the motor room Tom looked to the machinery, and
+ adjusted some of the auxiliary oil feeders. The various pieces of
+ apparatus were working well, though the engine had not yet been speeded up
+ to its limit. Tom wanted it to &ldquo;warm-up&rdquo; first.
+ </p>
+ <p>
+ &ldquo;Everything all right?&rdquo; asked Mr. Damon, as Tom rejoined them in the pilot
+ house, which was just forward of the living room in the main cabin.
+ </p>
+ <p>
+ &ldquo;Yes, I can't imagine what made Rad act that way. But I'll set the
+ automatic steering gear now, Mr. Damon, and then you will be relieved.&rdquo;
+ </p>
+ <p>
+ Mr. Jenks was gazing off toward the west&mdash;to where he hoped to
+ discover the secret of Phantom Mountain.
+ </p>
+ <p>
+ &ldquo;How do you like it?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;It's great,&rdquo; replied the diamond man. &ldquo;I've never been in an airship
+ before, and it's different than what I expected; but it's great! It's the
+ only craft that will serve our purpose among the towering mountain peaks,
+ where the diamond makers are hidden. I hope we can find them.&rdquo;
+ </p>
+ <p>
+ In a little while the Red Cloud was skimming along at faster speed, guided
+ by the automatic rudders, so that no one was needed in the pilot house,
+ since there was no danger of collisions. Airships are not quite numerous
+ enough for that, yet, though they may soon become so.
+ </p>
+ <p>
+ Tom and the others devoted several hours to arranging their staterooms and
+ bunks, and getting their clothing stowed away, and when this was done Mr.
+ Parker and Mr. Jenks sat gazing off into space.
+ </p>
+ <p>
+ &ldquo;It's hard to realize that we are really in an airship,&rdquo; observed the
+ diamond man. &ldquo;At first I thought I would be frightened, but I'm not a bit.
+ It doesn't seem as if anything could happen.&rdquo;
+ </p>
+ <p>
+ &ldquo;Something is likely to happen soon,&rdquo; said Mr. Parker, suddenly, as he
+ gazed at some weather instruments on the cabin wall.
+ </p>
+ <p>
+ &ldquo;Bless my soul! Don't say that!&rdquo; cried Mr. Damon. &ldquo;What is it?&rdquo;
+ </p>
+ <p>
+ &ldquo;I think, from my observations, that we will soon have a hurricane,&rdquo; said
+ the scientific man. &ldquo;There is every indication of it;&rdquo; and he seemed quite
+ delighted at the prospect of his prediction coming true.
+ </p>
+ <p>
+ &ldquo;A hurricane!&rdquo; cried Mr. Damon. &ldquo;I hope it isn't like the one that blew us
+ to Earthquake Island.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I think there will be no danger,&rdquo; spoke Tom. &ldquo;If it comes on to blow
+ we will ascend or descend out of the path of the storm. This craft is not
+ like the ill-fated Whizzer. I can more easily handle the Red Cloud; even
+ in a bad storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm glad to hear that,&rdquo; remarked Mr. Jenks. &ldquo;It would be too bad to be
+ wrecked before we got to Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I predict that we will have a bad storm,&rdquo; insisted Mr. Parker, and
+ Tom could not help wishing that the scientist would keep his gloomy
+ forebodings to himself.
+ </p>
+ <p>
+ However the storm had not developed up to noon, when Tom, with Mr. Damon's
+ help, served a fine meal in the dining-room. In the afternoon the speed of
+ the ship was increased, and by night they had covered several hundred
+ miles. Through the darkness the Red Cloud kept on, making good time. Tom
+ got up, occasionally, to look to the machinery, but it was all
+ automatically controlled, and an alarm bell would sound in his stateroom
+ when anything went wrong.
+ </p>
+ <p>
+ &ldquo;Bless my napkin!&rdquo; exclaimed Mr. Damon the next morning, as they sat down
+ to a breakfast of fruit, ham and eggs and fragrant coffee, &ldquo;this is living
+ as well as in a hotel, and yet we are&mdash;how far are we above the
+ earth, Tom?&rdquo; he asked, turning to the young inventor.
+ </p>
+ <p>
+ &ldquo;About two miles now. I just sent her up, as I thought I detected that
+ storm Mr. Parker spoke of.&rdquo;
+ </p>
+ <p>
+ &ldquo;I told you it would come,&rdquo; declared the scientist, and there was a small
+ hurricane below them that morning, but only the lower edge of it caught
+ the Red Cloud, and when Tom sent her up still higher she found a
+ comparatively quiet zone, where she slid along at good speed.
+ </p>
+ <p>
+ That afternoon Tom busied himself about some wires and a number of
+ complicated pieces of apparatus which were in one corner of the main
+ cabin.
+ </p>
+ <p>
+ &ldquo;What are you doing now?&rdquo; asked Mr. Jenks, who had been talking with Mr.
+ Parker, and showing that scientist some of the manufactured diamonds.
+ </p>
+ <p>
+ &ldquo;Getting our wireless apparatus in shape,&rdquo; answered the lad. &ldquo;I should
+ have done it before, but I had so much to do that I couldn't get at it.
+ I'm going to send off some messages. Dad will want to know how we are
+ doing.&rdquo;
+ </p>
+ <p>
+ As he worked away, he also made up his mind to send another message, in
+ care of his father, for there was a receiving station in the Swift home.
+ And to whom this message was addressed Tom did not say, but we fancy some
+ of our readers can guess.
+ </p>
+ <p>
+ Finally, after several hours of work, the wireless was in shape to send
+ and receive messages. Tom pulled over the lever, and a crackling sound was
+ heard, as the electricity leaped from the transmitters into space. Then he
+ clamped the receiver on his ear.
+ </p>
+ <p>
+ &ldquo;All ready,&rdquo; he announced. &ldquo;Has anybody any messages they wish sent?&rdquo; For,
+ with the courtesy of a true host he was ready to serve his guests before
+ he forwarded his own wireless notes.
+ </p>
+ <p>
+ &ldquo;Just tell my wife that I'm enjoying myself,&rdquo; requested Mr. Damon. &ldquo;Bless
+ my footstool! But this is great! We're off the earth yet, connected with
+ it.&rdquo;
+ </p>
+ <p>
+ Mr. Jenks had no one to whom he wanted to send any word, but Mr. Parker
+ wish to wire to a fellow scientist the result of some observations made in
+ the upper air.
+ </p>
+ <p>
+ Tom noted all the messages down, and then, when all was in readiness he
+ began to call his home station. He knew that either his father or Mr.
+ Jackson, the engineer, could receive the wireless.
+ </p>
+ <p>
+ But, no sooner had the young inventor sent off the first few dots and
+ dashes representing &ldquo;S. I.&rdquo;&mdash;his home station call&mdash;than he
+ started and a look of surprise came over his face.
+ </p>
+ <p>
+ &ldquo;They're calling us!&rdquo; he exclaimed.
+ </p>
+ <p>
+ &ldquo;Who is?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;My house&mdash;my father. He&mdash;he's been trying to get us ever since
+ we started, but I didn't have the wireless in shape to receive messages.
+ Oh, I hope it's not too late!&rdquo;
+ </p>
+ <p>
+ &ldquo;Too late! Bless my soul, too late for what?&rdquo; gasped Mr. Damon, somewhat
+ alarmed by Tom's manner.
+ </p>
+ <p>
+ The lad did not answer at once. He was intently listening to a series of
+ dots and dashes that clicked in the telephone receiver clamped to his left
+ ear. On his face there was a look of worriment.
+ </p>
+ <p>
+ &ldquo;Father has just sent me a message,&rdquo; he said. &ldquo;It's a warning flashed
+ through space! He's been trying to get it to me since yesterday!&rdquo;
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; asked Mr. Jenks, rising from his seat.
+ </p>
+ <p>
+ &ldquo;The mysterious man is aboard the airship&mdash;hidden away!&rdquo; cried Tom.
+ &ldquo;That's what Eradicate was trying to call to our attention as we started
+ off. Eradicate saw his face at a rear window, and tried to warn us! The
+ mysterious man is a stowaway on board!&rdquo;
+ </p>

+ <h2>
+ CHAPTER X&mdash;DROPPING THE STOWAWAY
+ </h2>
+ <p>
+ Tom's excited announcement startled Mr. Damon and the others as much as if
+ the young inventor had informed them that the airship had exploded and was
+ about to dash with them to the earth. The men leaped to their feet, and
+ stared at the lad.
+ </p>
+ <p>
+ &ldquo;A stowaway on board!&rdquo; cried Mr. Damon. &ldquo;Bless my soul! How did he&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;Are you sure that message is straight?&rdquo; asked Mr. Jenks. &ldquo;Did Eradicate
+ see the man?&rdquo;
+ </p>
+ <p>
+ &ldquo;He says he did,&rdquo; answered Tom. &ldquo;The man is hidden away on board now&mdash;probably
+ among the stores and supplies.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my tomato sauce!&rdquo; exploded Mr. Damon. &ldquo;I hope he doesn't eat them
+ all up!&rdquo;
+ </p>
+ <p>
+ &ldquo;We must get him out at once!&rdquo; declared Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I knew something would happen on this voyage,&rdquo; came from Mr. Parker. &ldquo;I
+ predicted it from the first!&rdquo;
+ </p>
+ <p>
+ Tom thought considerable, but he did not answer the scientist just then.
+ Another communication was coming to him by wireless. He listened intently.
+ </p>
+ <p>
+ &ldquo;Father says,&rdquo; the lad told his companions &ldquo;that Eradicate only had a
+ glimpse of the man at the last moment. He was looking from the rear
+ storeroom window&mdash;he's the same man who called on me that time&mdash;Rad
+ remembers him very well.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my shoes! What's to be done?&rdquo; inquired Mr. Damon, looking around
+ helplessly.
+ </p>
+ <p>
+ &ldquo;We must get him out, that's all,&rdquo; decided Mr. Jenks; with vigor. &ldquo;Get him
+ out and drop him overboard!&rdquo;
+ </p>
+ <p>
+ &ldquo;Drop him overboard!&rdquo; cried Mr. Parker, in horror.
+ </p>
+ <p>
+ &ldquo;Not exactly, but get rid of him,&rdquo; proceeded the diamond seeker. &ldquo;That man
+ is one of my enemies. He has been sent by the band of diamond makers
+ hidden among the mountains, to spy on me, and, if possible, prevent me
+ from seeking to discover their secret. He tried to work on Tom's Swift's
+ fears, and frighten him from using his airship on this quest. Then, when
+ he failed, the man must have sneaked into the shed, and hidden himself in
+ the ship. We must get rid of him, or he may wreck the Red Cloud!&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so!&rdquo; cried Tom. &ldquo;We must try to capture him. I think we had better&mdash;&rdquo;
+ the lad paused, and again listened to the wireless message. &ldquo;Father says
+ Eradicate saw the man have a gun, so we must be careful,&rdquo; the young
+ inventor translated the dots and dashes.
+ </p>
+ <p>
+ &ldquo;Bless my powder horn!&rdquo; exploded Mr. Damon.
+ </p>
+ <p>
+ &ldquo;We shall have to proceed cautiously then,&rdquo; spoke Mr. Jenks. &ldquo;If he is
+ like any others in the gang he is a desperate man.&rdquo;
+ </p>
+ <p>
+ &ldquo;Better sneak up on him then, if we can,&rdquo; proposed Mr. Parker. &ldquo;There are
+ enough of us to cope with one man, even if he is armed. You have weapons
+ aboard, haven't you?&rdquo; he inquired of Tom.
+ </p>
+ <p>
+ &ldquo;Yes,&rdquo; was the hesitating answer, &ldquo;but I don't want to use them if I can
+ help it. Not only because of the danger, and a dislike of shedding blood,
+ but because a stray bullet might pierce the gas bag and damage the ship.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so,&rdquo; agreed Mr. Jenks. &ldquo;Well, I guess if we go at it the right way
+ we can capture him without any shooting. But we must talk more quietly&mdash;we
+ ought to have whispered&mdash;he may have heard us.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't think so,&rdquo; replied Tom. &ldquo;The storeroom is far enough off so that
+ he couldn't hear us. Besides, the motor makes such a racket that he
+ couldn't distinguish what we were talking about, even if he heard our
+ voices. So, unless he heard the wireless working, and suspects something
+ from that, he probably doesn't know that we are aware of his presence
+ aboard.&rdquo;
+ </p>
+ <p>
+ &ldquo;But why do you think he has remained quiet all this while, Tom?&rdquo; asked
+ Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Probably he wants to wait until the ship is farther out west,&rdquo; suggested
+ Mr. Jenks. &ldquo;Then he will be nearer his friends, and can get help, if he
+ needs it.&rdquo;
+ </p>
+ <p>
+ &ldquo;And do you really believe he would destroy the Red Cloud?&rdquo; asked Mr.
+ Parker.
+ </p>
+ <p>
+ &ldquo;I think that all he is waiting for is a favorable chance,&rdquo; declared the
+ diamond seeker. &ldquo;He would destroy the craft, and us too, if he could
+ prevent us from discovering the secret of Phantom Mountain, I believe.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we must get ahead of him,&rdquo; decided Tom, quietly. &ldquo;I have just
+ flashed to dad a message, telling him that we will heed his warning. Now
+ to capture the stowaway!&rdquo;
+ </p>
+ <p>
+ &ldquo;And while we're about it, give him a good scare when we do get him,&rdquo;
+ suggested Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;How?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Threaten to drop him overboard. Perhaps that will make him tell how he
+ happened to get in our ship, and what are the plans of the gang of diamond
+ makers. We may get valuable information that way.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe you can scare such fellows much,&rdquo; was Tom's opinion, but
+ it was agreed to try.
+ </p>
+ <p>
+ &ldquo;How are you going to capture him?&rdquo; asked Mr. Parker. &ldquo;If he has a gun it
+ won't be any too easy to go in the storeroom, and drag him out.&rdquo;
+ </p>
+ <p>
+ &ldquo;We'll have to use a little strategy,&rdquo; decided Tom, and then they
+ discussed several plans. The one finally adopted was that Tom and Mr.
+ Damon should enter the storeroom, casually, as if in search of food to
+ cook for supper. They would discuss various dishes, and Mr. Damon was to
+ express a preference for something in the food line, the box containing
+ which, was well back in the room. This would give the two a chance to
+ penetrate to the far end of the apartment, without arousing the suspicions
+ of the hidden man, who, doubtless, would be listening to the conversation.
+ </p>
+ <p>
+ &ldquo;And as soon as we get sight of him, you and I will jump right at him, Mr.
+ Damon,&rdquo; said Tom. &ldquo;Jump before he has a chance to use his gun. Mr. Jenks
+ and Mr. Parker will be waiting outside the room, to catch him if he gets
+ away from us. I'll have some ropes ready, and we'll tie him up, and&mdash;well,
+ we'll decide later what to do with him.&rdquo;
+ </p>
+ <p>
+ &ldquo;All right. I'm ready as soon as you are, Tom,&rdquo; said the eccentric man.
+ &ldquo;Come ahead.&rdquo;
+ </p>
+ <p>
+ They went softly to the storeroom, and listened at the door. There was no
+ sound heard save that made by the machinery.
+ </p>
+ <p>
+ &ldquo;I wonder if he's really here?&rdquo; whispered Mr. Damon.
+ </p>
+ <p>
+ &ldquo;We'll soon find out,&rdquo; answered Tom. &ldquo;Let's go in.&rdquo;
+ </p>
+ <p>
+ They entered, and, in pursuance of their plan, Tom and his friend talked
+ of various foods.
+ </p>
+ <p>
+ &ldquo;I think I'd like some of that canned lobster, with French dressing on,&rdquo;
+ spoke the eccentric man.
+ </p>
+ <p>
+ &ldquo;That's away in the back end of the room,&rdquo; said Tom, in a loud voice.
+ &ldquo;It's under a lot of boxes.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then I'll help you get it out! Bless my frying pan! but I am very fond of
+ lobster!&rdquo; exclaimed Mr. Damon, in as natural tones as was possible under
+ the circumstances.
+ </p>
+ <p>
+ He and Tom moved cautiously back among the boxes and barrels. They were
+ glancing about with eager eyes. Tom switched on an electric light, and,
+ the instant he did so, he was aware of a movement in a little space formed
+ by one box which was placed on top, of two others. The lad saw a dark
+ figure moving, as if to get farther out of sight.
+ </p>
+ <p>
+ &ldquo;I've got him!&rdquo; cried Tom, making a dive for the shadow.
+ </p>
+ <p>
+ A moment later the young inventor was bowled over, as a dark figure leaped
+ over his head.
+ </p>
+ <p>
+ &ldquo;Catch him, Mr. Damon!&rdquo; he cried.
+ </p>
+ <p>
+ &ldquo;Bless my hatband! I&mdash;I&mdash;&rdquo; Mr. Damon's voice ended in a grunt.
+ He, too, had been knocked down by the fleeing man.
+ </p>
+ <p>
+ &ldquo;Look out, Mr. Jenks!&rdquo; cried Tom, to warn those on guard at the door of
+ the storeroom.
+ </p>
+ <p>
+ There was the report of a gun, some excited shouts, and when Tom could
+ scramble to his feet, and rush out, he beheld Mr. Parker calmly sitting on
+ a struggling man, while Mr. Jenks held a gun, that was still smoking.
+ </p>
+ <p>
+ &ldquo;We caught him!&rdquo; cried the scientist.
+ </p>
+ <p>
+ &ldquo;Anybody hurt?&rdquo; asked Tom, anxiously.
+ </p>
+ <p>
+ &ldquo;No, I knocked up his gun as he fired,&rdquo; explained Mr. Jenks. &ldquo;Where are
+ the ropes, Tom?&rdquo;
+ </p>
+ <p>
+ The cords were produced and the man, who had now ceased to struggle, was
+ tightly bound. He uttered not a word, but he smiled grimly when Mr. Damon
+ remarked:
+ </p>
+ <p>
+ &ldquo;I guess I'll go back in the storeroom, Tom, and see how much food he
+ ate.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I guess he didn't take much,&rdquo; declared the lad. &ldquo;He wasn't there long
+ enough.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, Farley Munson, so it's you, is it?&rdquo; asked Mr. Jenks, as he surveyed
+ the prisoner.
+ </p>
+ <p>
+ &ldquo;Do you know him?&rdquo; asked Tom, in some surprise.
+ </p>
+ <p>
+ &ldquo;He was in with the diamond makers,&rdquo; said Mr. Jenks. &ldquo;He was one of those
+ who took me to the secret cave. But it will be the last time he ever goes
+ there. How high up are we, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;About two miles. Why?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess that will be far enough to let him fall,&rdquo; went on the diamond
+ seeker. &ldquo;Come on, Mr. Damon, help me throw him overboard!&rdquo;
+ </p>
+ <p>
+ &ldquo;You&mdash;you're not going to throw me over&mdash;with the airship two
+ miles high; are you?&rdquo; gasped the man.
+ </p>
+ <p>
+ &ldquo;Will you tell us what we want to know, if we don't?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;What do you want to know?&rdquo;
+ </p>
+ <p>
+ &ldquo;How you got aboard, and what your object was in coming.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's easy enough. I had been hanging around the shed for several days,
+ watching a chance to get in. Finally I saw it, when that colored man went
+ to feed his mule, and I slipped in, and hid in the airship. The stores
+ were all in then, and I stowed myself away among the boxes. I had food and
+ water, so I didn't touch any of yours,&rdquo; and he looked at Mr. Damon, who
+ seemed much relieved.
+ </p>
+ <p>
+ &ldquo;And what was your object?&rdquo; demanded Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I wanted to prevent you from going to Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;How?&rdquo;
+ </p>
+ <p>
+ &ldquo;By destroying the airship if need be. But I hoped to accomplish it by
+ other means. I would have stopped at nothing, though, to prevent you. You
+ must keep away from there!&rdquo;
+ </p>
+ <p>
+ &ldquo;And if we refuse?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Then you'll have to take what comes!&rdquo;
+ </p>
+ <p>
+ &ldquo;But not from you!&rdquo; exclaimed Mr. Jenks. &ldquo;We're going to get rid of you.&rdquo;
+ </p>
+ <p>
+ The man's face showed the alarm he felt.
+ </p>
+ <p>
+ &ldquo;Oh, don't worry,&rdquo; said Mr. Jenks, quickly, &ldquo;we're not going to toss you
+ overboard. We're not as desperate as your crowd. But we're going to get
+ rid of you, and then go on before you can send any word to your
+ confederates. We'll put you off in the most lonesome spot we can find, and
+ I guess you'll be some time getting back to civilization. By that time
+ we'll have the secret of the diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;You never will!&rdquo; declared the man, firmly. And he would say nothing more,
+ though by threats and promises Mr. Jenks tried to get from him something
+ about the men in with him, and where the cave of the diamonds was located.
+ </p>
+ <p>
+ Heavily bound with ropes the man was locked in a small closet, to be kept
+ there until a favorable spot was reached for letting him go. Mr. Jenks'
+ plan, of dropping him down in some place where he would have difficulty in
+ sending on word to his confederates was considered a good one.
+ </p>
+ <p>
+ Three days later, in crossing over a lonely region, near the Nebraska
+ National Forest, Farley Munson, which was one of the names the spy went
+ by, was dropped off the airship, when it was sent down to within a few
+ feet of the earth.
+ </p>
+ <p>
+ &ldquo;It will take you some time to get to a telegraph office,&rdquo; said Mr. Jenks,
+ as a package of food, and a flask of water was tossed down to the
+ stowaway. He shook his fist at those in the airship, and shouted after
+ them:
+ </p>
+ <p>
+ &ldquo;You'll never discover the secret of Phantom Mountain!&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, we will,&rdquo; declared Tom, as he sent the Red Cloud high into the air
+ again.

+ <h2>
+ CHAPTER XI&mdash;A WEARY SEARCH
+ </h2>
+ <p>
+ During the three days when the stowaway had been kept a prisoner, the Red
+ Cloud had made good time on her western trip. She was now about two
+ hundred and fifty miles from Leadville, Colorado, and Tom knew he could
+ accomplish that distance in a short time. It was necessary, therefore,
+ since they were so close to the place where the real search would begin,
+ to make some more definite plans.
+ </p>
+ <p>
+ &ldquo;We will need to replenish our supply of gasoline,&rdquo; said Tom, shortly
+ after the stowaway had been dropped, and when the young inventor had made
+ a general inspection of the airship.
+ </p>
+ <p>
+ &ldquo;Is it all gone?&rdquo; inquired Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Not all, but we will soon be in the wildest part of the Rocky Mountains,
+ and gasoline is difficult to procure there. So I want to fill all our
+ reserve tanks. But I would rather do that before we get far into
+ Colorado.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo; inquired Mr. Parker.
+ </p>
+ <p>
+ &ldquo;Because airships are not so common but what the appearance of one
+ attracts attention. Ours is sure to be talked about, and commented on. In
+ that case, in spite of our precaution in putting Munson off in this lonely
+ place, word of the Red Cloud being in the vicinity of Leadville may reach
+ the diamond makers, and put them on their guard. We want to take them
+ unawares if we can.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so,&rdquo; agreed Mr. Jenks. &ldquo;We had better get our gasoline at the
+ first stopping place, then, and proceed with our search. Our first object
+ ought to be to look for the landmark&mdash;the head of stone. Then we can
+ begin to prospect about a bit.&rdquo;
+ </p>
+ <p>
+ &ldquo;My idea, exactly,&rdquo; declared Tom. &ldquo;Well, then, I'll go down at the first
+ place we cross, where we can get gasoline, and then we'll be in a position
+ to hover in the air for a long time, without descending.&rdquo;
+ </p>
+ <p>
+ The airship kept on her way, traveling slowly the remainder of that day,
+ and at dusk, when there was less chance of big crowds seeing them, the Red
+ Cloud was sent down on the outskirts of a large village. Tom and Mr. Damon
+ went to a supply store, and arranged to have a sufficient quantity of the
+ gasoline taken out to the airship. It was delivered after dark, and little
+ talk was occasioned by the few who were aware of the presence of the
+ craft. Then, once more, they went aloft, and Tom sent several wireless
+ messages to Shopton, including one to Miss Nestor.
+ </p>
+ <p>
+ &ldquo;Please tell my wife that I am well, and that I have a good appetite,&rdquo;
+ said Mr. Damon.
+ </p>
+ <p>
+ Mr. Parker also sent a message to a scientific friend of his, stating that
+ he made some observations among the mountains, of the region in which the
+ airship then was, and that the indications were that a great landslide
+ would soon take place.
+ </p>
+ <p>
+ &ldquo;That won't worry us,&rdquo; spoke Tom, &ldquo;for we'll be far above it.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope we will be near enough to enable me to observe it, and make some
+ scientific notes,&rdquo; came from Mr. Parker. &ldquo;I am positive that one of these
+ mountain peaks that we saw to-day will disappear in a landslide within a
+ few days. I have an instrument somewhat like the one that records
+ earthquakes, and it has been acting strangely of late.&rdquo;
+ </p>
+ <p>
+ Tom wondered what enjoyment Mr. Parker got out of life, when he was always
+ looking for some calamity to happen, but the scientist seemed to take as
+ much pleasure in his gloomy forebodings now, as he had on Earthquake
+ Island.
+ </p>
+ <p>
+ They reached the vicinity of Leadville the next day, but took care to keep
+ high above the city, so that the airship could not be observed. With
+ powerful glasses they examined the mountainous country, looking for the
+ little settlement of Indian Ridge.
+ </p>
+ <p>
+ &ldquo;There it is!&rdquo; exclaimed Mr. Jenks, just as dusk was settling down. &ldquo;I can
+ make out the hotel I stopped at. Now we can really begin our search. The
+ next thing is to find the stone head, and then, I think, I will have my
+ bearings.&rdquo;
+ </p>
+ <p>
+ &ldquo;We'll begin the hunt for that landmark in the morning,&rdquo; said Tom.
+ </p>
+ <p>
+ High in the air hovered the Red Cloud. At that distance above the earth
+ she must have looked like some great bird, and the adventurers thought it
+ unlikely that any one in the vicinity of Leadville would observe them.
+ </p>
+ <p>
+ The quest for the great mountain peak, that looked like a stone head, was
+ under way. Back and forth sailed the airship. Sometimes she was enveloped
+ in fog, and no sight could be had of the earth below. At other times there
+ were rain storms, which likewise prevented a view. Mr. Parker was on the
+ lookout for his predicted mountain landslide, but it did not occur, and he
+ was much disappointed.
+ </p>
+ <p>
+ &ldquo;It's queer I can't pick out that landmark,&rdquo; said Mr. Jenks after two days
+ of weary searching, when their eyes were strained from long peering
+ through telescopes. &ldquo;I'm sure it was around Indian Ridge, yet we've
+ covered almost all the ground in this neighborhood, and I haven't had a
+ glimpse of it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps it was destroyed in a landslide, or some cataclysm of nature,&rdquo;
+ suggested Mr. Parker. &ldquo;That is very possible.&rdquo;
+ </p>
+ <p>
+ &ldquo;If that's the case we're going to have a hard time to locate the cave of
+ the diamond makers,&rdquo; answered Mr. Jenks, &ldquo;but I hope it isn't so.&rdquo;
+ </p>
+ <p>
+ They continued the search for another day, and then Tom, as they sat in
+ the comfortable cabin of the airship that night, hovering almost
+ motionless (for the motor had been shut down) made a proposition.
+ </p>
+ <p>
+ &ldquo;Why not descend in some secluded place,&rdquo; he suggested, &ldquo;and wander around
+ on foot, making inquiries of the miners. They may know where the stone
+ head is, or they may even know about Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Good idea,&rdquo; spoke Mr. Jenks. &ldquo;We'll do it.&rdquo;
+ </p>
+ <p>
+ Accordingly, the next morning, the Red Cloud was lowered in a good but
+ lonely landing place, and securely moored. It was in a valley, well
+ screened from observation, and the craft was not likely to be seen, but,
+ to guard against any damage being done to it by passing hunters or miners,
+ Mr. Parker and Mr. Damon agreed to remain on guard in it, while Tom and
+ Mr. Jenks spent a day or two traveling around, making inquiries.
+ </p>
+ <p>
+ The young inventor and his companion proceeded on foot to a small
+ settlement, where they hired horses on which to make their way about. They
+ were to be gone two days, and in that time they hoped to get on the right
+ trail.

+ <h2>
+ CHAPTER XII&mdash;THE GREAT STONE HEAD
+ </h2>
+ <p>
+ It was a wild and desolate country in which Tom Swift and Mr. Jenks were
+ traveling. Villages were far apart, and they were at best but small
+ settlements. In their journeys from place to place they met few travelers.
+ </p>
+ <p>
+ But of these few they made cautious inquiries as to the location of
+ Phantom Mountain, or the landmark known as the great stone head.
+ Prospectors, miners and hunters, whom they asked, shook their heads.
+ </p>
+ <p>
+ &ldquo;I've heard of Phantom Mountain,&rdquo; said one grizzled miner, &ldquo;but I couldn't
+ say where it is. Maybe it's only a fish story&mdash;the place may not even
+ exist.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, it does, for I've been there!&rdquo; exclaimed Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Then why don't you go back to it?&rdquo; asked the miner.
+ </p>
+ <p>
+ &ldquo;Because I can't locate it again,&rdquo; was the reply.
+ </p>
+ <p>
+ &ldquo;Humph! Mighty queer if you've seen a place once, and can't get to it
+ again,&rdquo; and the man looked as if he thought there was something strange
+ about Tom and his companion. Mr. Jenks did not want to say that he had
+ been taken to the mountain blindfolded, for that would have caused too
+ much talk.
+ </p>
+ <p>
+ &ldquo;I think if we spent to-night in a place where the miners congregate,
+ listened to their talk, and put a few casual questions to them, more as if
+ we were only asking out of idle curiosity, we might learn something,&rdquo;
+ suggested Tom.
+ </p>
+ <p>
+ &ldquo;Very well, we'll try that scheme.&rdquo;
+ </p>
+ <p>
+ Accordingly, after they had left the suspicious miner the two proceeded to
+ a small milling town, not far from Indian Ridge. There they engaged rooms
+ for the night at the only hotel, and, after supper they sat around the
+ combined dance hall and gambling place.
+ </p>
+ <p>
+ There were wild, rough scenes, which were distasteful to Tom, and to Mr.
+ Jenks, but they felt that this was their only chance to get on the right
+ trail, and so they stayed. As strangers in a western mining settlement
+ they were made roughly welcome, and in response to their inquiries about
+ the country, they were told many tales, some of which were evidently
+ gotten up for the benefit of the &ldquo;tenderfeet.&rdquo;
+ </p>
+ <p>
+ &ldquo;Is there a place around here called Phantom Mountain?&rdquo; asked Tom, at
+ length, as quietly as he could.
+ </p>
+ <p>
+ &ldquo;Never heard of it, stranger,&rdquo; replied a miner who had done most of the
+ talking. &ldquo;I never heard of it, and what Bill Slatterly don't know ain't
+ worth knowin'. I'm Bill Slatterly,&rdquo; he added, lest there be some doubt on
+ that score.
+ </p>
+ <p>
+ &ldquo;Isn't there some sort of a landmark around here shaped like a great stone
+ head?&rdquo; went on Tom, after some unimportant questions. &ldquo;Seems to me I've
+ heard of that.&rdquo;
+ </p>
+ <p>
+ &ldquo;Nary a one,&rdquo; answered Mr. Slatterly. &ldquo;No stone heads, and no Phantom
+ Mountains&mdash;nary a one.
+ </p>
+ <p>
+ &ldquo;Who says there ain't no Phantom Mountains?&rdquo; demanded an elderly miner,
+ who had been dozing in one corner of the room, but who was awakened by
+ Slatterly's loud voice. &ldquo;Who says so?&rdquo;
+ </p>
+ <p>
+ &ldquo;I do,&rdquo; answered the one who claimed to know everything.
+ </p>
+ <p>
+ &ldquo;Then you're wrong!&rdquo; Tom's heart commenced beating faster than usual.
+ </p>
+ <p>
+ &ldquo;Do you mean to say you've seen Phantom Mountain, Jed Nugg?&rdquo; demanded
+ Slatterly.
+ </p>
+ <p>
+ &ldquo;No, I ain't exactly seen it, an' I don't want to, but there is such a
+ place, about sixty mile from here. Folks says it's haunted, and them sort
+ of places I steer clear from.&rdquo;
+ </p>
+ <p>
+ &ldquo;Can you tell me about it?&rdquo; asked Mr. Jenks, eagerly. &ldquo;I am interested in
+ such things.&rdquo;
+ </p>
+ <p>
+ &ldquo;I can't tell you much about it,&rdquo; was the reply, &ldquo;and I wouldn't git too
+ interested, if I was you. It might not be healthy. All I know is that one
+ time my partner and I were in hard luck. We got grub-staked, and went out
+ prospectin'. We strayed into a wild part of the country about sixty mile
+ from here, and one night we camped on a mountain&mdash;a wild, desolate
+ place it was too.&rdquo;
+ </p>
+ <p>
+ The miner stopped, and began leisurely filling his pipe.
+ </p>
+ <p>
+ &ldquo;Well?&rdquo; asked Tom, trying not to let his voice sound too eager.
+ </p>
+ <p>
+ &ldquo;Well, that was Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ The miner seemed to have finished his story.
+ </p>
+ <p>
+ &ldquo;Is that all?&rdquo; asked Mr. Jenks. &ldquo;How did you know it was Phantom
+ Mountain?&rdquo;
+ </p>
+ <p>
+ &ldquo;'Cause we seen the ghost&mdash;my partner and I&mdash;that's why!&rdquo;
+ exclaimed the man, puffing on his pipe. &ldquo;As I said, we was campin' there,
+ and 'long about midnight we seen somethin' tall and white, and all
+ shimmerin', with a sort of yellow fire, slidin' down the side of the
+ mountain. It made straight for our camp.&rdquo;
+ </p>
+ <p>
+ &ldquo;Huh! Guess you run, didn't you, Jed?&rdquo; asked Bill Slatterly.
+ </p>
+ <p>
+ &ldquo;Course we did. You'd a run too, if you seen a ghost comm' at you, an'
+ firin' a gun.&rdquo;
+ </p>
+ <p>
+ &ldquo;Ghosts can't fire guns!&rdquo; declared Bill. &ldquo;I guess you dreamed it, Jed.&rdquo;
+ </p>
+ <p>
+ &ldquo;Ghosts can't fire guns, eh? That's all you know about it. This one did,
+ and to prove I didn't dream it, there was a bullet hole in my hat next
+ mornin'. I could prove it, too, only I ain't got that hat any more. But
+ that was Phantom Mountain, strangers, an' my advice to you is to keep away
+ from it. I was on it but I didn't exactly see it, 'cause it was dark at
+ the time.&rdquo;
+ </p>
+ <p>
+ &ldquo;Was it near a peak that looked like a stone head?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;It were, stranger, but I didn't take much notice of it. Me and my partner
+ got out of them diggin's next day, and I never went back. I ain't never
+ said much about this place, but it's called Phantom Mountain all right,
+ and I ain't the only one that's seen a ghost there. Other grub-stakers has
+ had the same experience.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why ain't I never heard about it?&rdquo; demanded Bill, suspiciously.
+ </p>
+ <p>
+ &ldquo;'Cause as why you're allers so busy talkin' that you don't never listen
+ to nothin' I reckon,&rdquo; was Jed's answer, amid laughter.
+ </p>
+ <p>
+ &ldquo;Can you tell us what trail to take to get there?&rdquo; asked Tom, of the
+ miner.
+ </p>
+ <p>
+ &ldquo;Yes, it's called the old silver trail, and you strike it by goin' to a
+ place called Black Gulch, about forty mile from here. Then it's twenty
+ mile farther on. But take my advice and don't go.&rdquo;
+ </p>
+ <p>
+ &ldquo;Can it be reached by way of Indian Ridge?&rdquo; asked Mr. Jenks, wondering how
+ he had been taken to the cave of the diamond makers. He did not remember
+ Black Gulch.
+ </p>
+ <p>
+ &ldquo;Yes, you can git there by Indian Ridge way, but it's more dangerous.
+ You're likely to lose your way, for that's a trail that's seldom
+ traveled.&rdquo; Mr. Jenks thought that, perhaps, was the reason the gang had
+ taken him that way. &ldquo;It's easier to get to the stone head and Phantom
+ Mountain by Black Gulch, but it ain't healthy to go there, strangers, take
+ my advice on that,&rdquo; concluded the miner, as he prepared to go to sleep
+ again.
+ </p>
+ <p>
+ Tom could scarcely contain the exultation he felt. At last, it seemed,
+ they were on the trail. He motioned to Mr. Jenks, and they slipped quietly
+ from the place, just as another dance was beginning.
+ </p>
+ <p>
+ &ldquo;Now for Black Gulch!&rdquo; cried Tom. &ldquo;We must hurry back to the airship, and
+ tell the good news.
+ </p>
+ <p>
+ &ldquo;It's too late to-night,&rdquo; decided Mr. Jenks, and so they waited until
+ morning, when they made an early start.
+ </p>
+ <p>
+ They found Mr. Damon and Mr. Parker anxiously awaiting their return. Mr.
+ Damon blessed so many things that he was nearly out of breath, and Mr.
+ Parker related something of the observations he had made.
+ </p>
+ <p>
+ &ldquo;I think I have discovered traces of a dormant volcano,&rdquo; he said. &ldquo;I am in
+ hopes that it will have an eruption while we are here.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm not,&rdquo; spoke Tom, decidedly. &ldquo;We'll start for Black Gulch as soon as
+ possible.&rdquo;
+ </p>
+ <p>
+ The airship once more rose in the air, and, following the directions the
+ miner had given him, Tom pointed his craft for the depression in the
+ mountains which had been given the name Black Gulch. It was reached in a
+ short time, and then, making a turn up a long valley the airship proceeded
+ at reduced speed.
+ </p>
+ <p>
+ &ldquo;We ought to see that stone head soon now,&rdquo; spoke Tom, as he peered from
+ the windows of the pilot house.
+ </p>
+ <p>
+ &ldquo;It's queer we didn't notice it when we were up in the air,&rdquo; remarked Mr.
+ Jenks. &ldquo;We've been over this place before, I'm sure of it.&rdquo;
+ </p>
+ <p>
+ The next moment Mr. Damon uttered a cry. &ldquo;Bless my watch-chain!&rdquo; he
+ exclaimed. &ldquo;Look at that!&rdquo;
+ </p>
+ <p>
+ He pointed off to the left. There, jutting out from the side of a steep
+ mountain peak was a mass of stone&mdash;black stone&mdash;which, as the
+ airship slowly approached, took the form and shape of a giant's head.
+ </p>
+ <p>
+ &ldquo;That's it! That's it!&rdquo; cried Tom. &ldquo;The great stone head!&rdquo;
+ </p>
+ <p>
+ &ldquo;And now for Phantom Mountain and the diamonds!&rdquo; shouted Mr. Jenks, as Tom
+ let the airship slowly settle to the bottom of the valley.

+ <h2>
+ CHAPTER XIII&mdash;ON PHANTOM MOUNTAIN
+ </h2>
+ <p>
+ Out from the Red Cloud piled Tom and the others. They made a rush for the
+ irregular mass of rock which bore so strong a resemblance to the head of
+ some gigantic man.
+ </p>
+ <p>
+ &ldquo;That's the one! That's the thing I saw when they were taking me along
+ here blindfolded!&rdquo; exclaimed Mr. Jenks. &ldquo;I'm sure we're on the right
+ trail, now!&rdquo;
+ </p>
+ <p>
+ &ldquo;But what gets me, though,&rdquo; remarked Mr. Damon, &ldquo;is why we couldn't see
+ that landmark when we were up in the air. We had a fine view, and ought to
+ have been able to pick it out with the telescopes.&rdquo;
+ </p>
+ <p>
+ The adventurers saw the reason a few seconds later. The image was visible
+ only from one place, and that was directly looking up the valley. If one
+ went too far to the right or left the head disappeared from view behind
+ jutting crags, and it was impossible to see it from overhead, because the
+ head was almost under a great spur of a mighty mountain.
+ </p>
+ <p>
+ &ldquo;We might have hunted for it a week in the airship, and been directly over
+ it,&rdquo; said Tom, &ldquo;and yet we would never have seen it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, but we never would have gotten here in such good shape if it hadn't
+ been for your wonderful craft,&rdquo; declared Mr. Jenks. &ldquo;It brought us here
+ safely and quickly, and enabled us to elude the men who tried to keep us
+ back. We're here in spite of them. If we had traveled by train they might
+ have interfered with us in a dozen ways.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so,&rdquo; agreed Mr. Damon. &ldquo;Well, now we're here, what's to be done?
+ Which way do we start to reach the cave where the diamonds are
+ manufactured, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;That I can't say. As you know, I only had a momentary glimpse of this
+ stone head as they were taking me along the trail. Then one of the men
+ noticed that the bandage had slipped and he pulled it into place. So I
+ really can't say which direction to take now, in order to discover the
+ secret.&rdquo;
+ </p>
+ <p>
+ &ldquo;How long after you saw the head before you reached the cave?&rdquo; asked Tom.
+ &ldquo;In that way we may be able to tell how far away it is.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I should say it was about two or three hours after I saw the head,
+ before we got to the halting place, and I was carried into the cave. That
+ would make it several miles from here, for we went in a wagon.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, and they might have driven in a round-about way, in order to deceive
+ you,&rdquo; suggested Mr. Damon. &ldquo;At best we have but a faint idea where the
+ diamond cave is, but we must search for it; eh, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Certainly. We'll start right in. And as the airship will be of but little
+ service to us now, I suggest that we leave it in this valley. It is very
+ much secluded, and no one will harm it, I think. We can then start off
+ prospecting, for I have a large portable tent, and we can carry enough
+ food with us, with what game we can shoot, to enable us to live. I have a
+ regular camping outfit on board.&rdquo;
+ </p>
+ <p>
+ &ldquo;Fine!&rdquo; cried Mr. Parker, &ldquo;and that will give me a chance to make some
+ observations among the mountains, and perhaps I can predict when a
+ landslide, or an eruption of some dormant volcano, may occur.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my stars!&rdquo; cried Mr. Damon. &ldquo;I don't wish you any bad luck, Mr.
+ Parker, but I sincerely hope nothing of the sort happens! We had enough of
+ that on Earthquake Island!&rdquo;
+ </p>
+ <p>
+ &ldquo;One can not halt the forces of nature,&rdquo; said the scientist, solemnly.
+ &ldquo;There are many towering peaks around here which may contain old
+ volcanoes. And I notice the presence of iron ore all about. This must be a
+ wonderful place in a thunder and lightning storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo; asked Tom, curiously.
+ </p>
+ <p>
+ &ldquo;Because lightning would be powerfully attracted here by the presence of
+ the metal. In fact there is evidence that many of the peaks have been
+ struck by lightning,&rdquo; and the scientist showed curious, livid scars on the
+ stone faces of the peaks within sight.
+ </p>
+ <p>
+ &ldquo;Then this is a good place to stay away from in a storm,&rdquo; observed Mr.
+ Damon. &ldquo;However, we won't worry about that now. If this is the landmark
+ Mr. Jenks was searching for, then we must be in the vicinity of Phantom
+ Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;I think we are,&rdquo; declared the diamond seeker. &ldquo;Probably it is within
+ sight now, but there are so many peaks, and this is such a wild and
+ desolate part of the country that we may have trouble in locating it.&rdquo;
+ </p>
+ <p>
+ &ldquo;We've got to make a beginning, anyhow,&rdquo; decided Tom, &ldquo;and the sooner the
+ better. Come, we'll make up our camping kits, and start out.&rdquo;
+ </p>
+ <p>
+ It was something to know that they were on the right trail, and it was a
+ relief to be able to busy oneself, and not be aimlessly searching for a
+ mysterious landmark. They all felt this, and soon the airship was taken to
+ a secluded part of the valley, where it was well hidden from sight in a
+ grove of trees.
+ </p>
+ <p>
+ Tom and Mr. Damon then served a good meal, and preparations were made to
+ start on their search among the mountains&mdash;a search which they hoped
+ would lead them to Phantom Mountain, and the cave of the diamond makers.
+ </p>
+ <p>
+ The tent which would afford them shelter was in sections, and could be
+ laced together. They carried food, compressed into small packages, coffee,
+ a few cooking utensils; and each one had a gun, Tom carrying a combination
+ rifle and shotgun, for game.
+ </p>
+ <p>
+ &ldquo;We can't live very high while we're on the trail,&rdquo; said the young
+ inventor, &ldquo;but it won't be much worse than it was on Earthquake Island.
+ Are we all ready?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess so,&rdquo; answered Mr. Damon. &ldquo;How long are we going to be away?&rdquo;
+ </p>
+ <p>
+ &ldquo;Until we find the diamond makers!&rdquo; declared Tom, firmly.
+ </p>
+ <p>
+ Shouldering their packs, the adventurers started off. Tom turned for a
+ last look at his airship, dimly seen amid the trees. Would he ever come
+ back to the Red Cloud? Would she be there when he did return? Would their
+ quest be successful? These questions the lad asked himself, as he followed
+ his companions along the rocky trail.
+ </p>
+ <p>
+ &ldquo;Perhaps we can find the road by which these men go in and out of the
+ cave,&rdquo; suggested Mr. Damon, when they had gone on for several miles.
+ </p>
+ <p>
+ &ldquo;I fancy not,&rdquo; replied Mr. Jenks. &ldquo;They probably take great pains to hide
+ it. I think though, that our best plan will be to go here and there,
+ looking for the entrance to the cave. I believe I would remember the
+ place.&rdquo;
+ </p>
+ <p>
+ &ldquo;But why can't you follow the directions given by the miner who told you
+ about Phantom Mountain?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Because his talk was too indefinite,&rdquo; answered Mr. Jenks. &ldquo;He was so
+ frightened by seeing what he believed to be a ghost, that he didn't take
+ much notice of the location of the place. All he knows is that Phantom
+ Mountain is somewhere around here.&rdquo;
+ </p>
+ <p>
+ &ldquo;And we've got to hunt until we find it; is that the idea?&rdquo; asked Mr.
+ Parker.
+ </p>
+ <p>
+ &ldquo;Or until we see the phantom,&rdquo; added Tom, in a low voice.
+ </p>
+ <p>
+ &ldquo;Bless my topknot!&rdquo; exclaimed Mr. Damon. &ldquo;You don't mean to say you expect
+ to see that ghost; do you Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps,&rdquo; answered the young inventor, and he did not add something else
+ of which he was thinking. For Tom had a curious theory regarding the
+ phantom.
+ </p>
+ <p>
+ They tramped about the remainder of that day. Toward evening Tom shot some
+ birds, which made a welcome addition to their supper. Then the tent was
+ put together, some spruce and hemlock boughs were cut to make a soft bed,
+ and on these, while the light of a campfire gleamed in on them, the
+ adventurers slept.
+ </p>
+ <p>
+ Their experience the following day was similar to the first. They saw no
+ evidence of a large cave such as Mr. Jenks had described, nor were there
+ any traces of men having gone back and forth among the mountains, as might
+ have been expected of the diamond makers, for, as Mr. Jenks had said, they
+ made frequent journeys to the settlement for food, and other supplies.
+ </p>
+ <p>
+ &ldquo;Well, I haven't begun to give up yet,&rdquo; announced Tom, on the third day,
+ when their quest was still unsuccessful. &ldquo;But I think we are making one
+ mistake.&rdquo;
+ </p>
+ <p>
+ &ldquo;What is that?&rdquo; inquired Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I think we should go up higher. In my opinion the cave is near the top of
+ some peak; isn't it, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I have that impression, though, as you know, I never saw the outside of
+ it. Still, it might not be a bad idea to ascend some of these peaks.&rdquo;
+ </p>
+ <p>
+ Following this suggestion, they laid their trail more toward the sky, and
+ that night found them encamped several thousand feet above the sea-level.
+ It was quite cool, and the campfire was a big one about which they sat
+ after supper, talking of many things.
+ </p>
+ <p>
+ Tom did not sleep well that night. He tossed from side to side on the bed
+ of boughs, and once or twice got up to replenish the fire, which had
+ burned low. His companions were in deep slumber.
+ </p>
+ <p>
+ &ldquo;I wonder what time it is?&rdquo; mused Tom, when he had been up the third time
+ to throw wood on the blaze. &ldquo;Must be near morning.&rdquo; He looked at his
+ watch, and was somewhat startled to see that it was only a little after
+ twelve. Somehow it seemed much later.
+ </p>
+ <p>
+ As he was putting the timepiece back into his pocket the lad looked around
+ at the dark and gloomy mountains, amid which they were encamped. As his
+ gaze wandered toward the peak of the one on the side of which the tent was
+ pitched, he gave a start of surprise.
+ </p>
+ <p>
+ For, coming down a place where, that afternoon, Tom had noticed a sort of
+ indefinite trail was a figure in white. A tall, waving figure, which
+ swayed this way and that&mdash;a figure which halted and then came on
+ again.
+ </p>
+ <p>
+ &ldquo;I wonder&mdash;I wonder if that can be a wisp of fog?&rdquo; mused the young
+ inventor. He rubbed his eyes, thinking it might be a swirling of the night
+ mist or a defect of vision. Then, as he saw more plainly, he noticed the
+ thing in white rushing toward him.
+ </p>
+ <p>
+ &ldquo;It's the phantom&mdash;the phantom!&rdquo; cried Tom, aloud. &ldquo;It's the thing
+ the miner saw! We're on Phantom Mountain now!&rdquo;

+ <h2>
+ CHAPTER XIV&mdash;WARNED BACK
+ </h2>
+ <p>
+ Tom's cries awakened the sleepers in the tent. Mr. Damon was the first to
+ rush out.
+ </p>
+ <p>
+ &ldquo;Bless my nightcap, Tom!&rdquo; he cried. &ldquo;What is it? What has happened? Are we
+ attacked by a mountain lion?&rdquo;
+ </p>
+ <p>
+ For answer the young inventor pointed up the mountain, to where, in the
+ dim light from a crescent moon, there stood boldly revealed, the figure in
+ white.
+ </p>
+ <p>
+ &ldquo;Bless&mdash;bless my very existence!&rdquo; cried the odd man. &ldquo;What is it,
+ Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;The phantom,&rdquo; was the quiet answer. &ldquo;Watch it, and see what it does.&rdquo;
+ </p>
+ <p>
+ By this time Mr. Jenks and Mr. Parker had joined Tom and Mr. Damon. The
+ four diamond seekers stood gazing at the apparition. And, as they looked,
+ the thing in white, seemingly too tall for any human being, slid slowly
+ forward, with a gliding motion. Then it raised its long, white arms, and
+ waved them threateningly at the adventurers.
+ </p>
+ <p>
+ &ldquo;It's motioning us to go back,&rdquo; said Mr. Parker in an awed whisper. &ldquo;It
+ doesn't want us to go any farther.&rdquo;
+ </p>
+ <p>
+ &ldquo;Very likely,&rdquo; agreed Tom, coolly. &ldquo;But we're not going to be frightened
+ by anything like that; are we?&rdquo;
+ </p>
+ <p>
+ &ldquo;Not much!&rdquo; exclaimed Mr. Jenks. &ldquo;I expected this. A ghost can't drive me
+ back from getting my rights from those scoundrels!&rdquo;
+ </p>
+ <p>
+ &ldquo;Suppose it uses a revolver to back up its demand?&rdquo; asked the scientist.
+ </p>
+ <p>
+ &ldquo;Wait until it does,&rdquo; answered Mr. Jenks. But the figure in white
+ evidently had no such intentions. It came on a little distance farther,
+ still waving the long arms threateningly, and then it suddenly
+ disappeared, seeming to dissolve in the misty shadows of the night.
+ </p>
+ <p>
+ &ldquo;Bless my suspenders!&rdquo; cried Mr. Damon. &ldquo;That's a very strange proceeding!
+ Very strange! What do you make of it, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;It is evidently some man dressed up in a sheet,&rdquo; declared Mr. Jenks. &ldquo;I
+ expected as much.&rdquo;
+ </p>
+ <p>
+ &ldquo;The work of those diamond makers; do you think?&rdquo; continued Mr. Damon.
+ </p>
+ <p>
+ &ldquo;I believe so,&rdquo; answered Tom, slowly, for he was trying to think it out.
+ &ldquo;I believe they are the cause of the phantom, though I don't know that
+ it's a man dressed in a sheet.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why isn't it?&rdquo; demanded Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Because it was too tall for a man, unless he's a giant.&rdquo;
+ </p>
+ <p>
+ &ldquo;He may have been on stilts,&rdquo; suggested Mr. Parker.
+ </p>
+ <p>
+ &ldquo;No man on stilts could walk along that way,&rdquo; declared Tom, confidently.
+ &ldquo;He glided along too easily. I am inclined to think it may be some sort of
+ a light.&rdquo;
+ </p>
+ <p>
+ &ldquo;A light?&rdquo; queried Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Yes, the diamond makers may be hidden in some small cave near here, and
+ they may have some sort of a magic lantern or a similar arrangement, for
+ throwing a shadow picture. They could arrange it to move as they liked,
+ and could cause it to disappear at will. That, I think, is the ghost we
+ have just seen.&rdquo;
+ </p>
+ <p>
+ &ldquo;But the diamond makers have only been in this mountain recently,&rdquo;
+ objected Mr. Jenks, &ldquo;and the phantom was here before them. In fact, that
+ was what gave the place its name.&rdquo;
+ </p>
+ <p>
+ &ldquo;That may be,&rdquo; admitted the lad. &ldquo;There are many places that have the name
+ of being haunted, but no one ever sees the ghost. It is always some one
+ else, who has heard of some one who has seen it. That may have been the
+ case here. I grant that this place may have been called 'Phantom Mountain'
+ for a number of years, due to the superstitious tales of miners. The
+ diamond makers came along, found the conditions just right for their work,
+ and adopted the ghost, so to speak. As there wasn't any real spirit they
+ made one, and they use it to scare people away. I think that's what we've
+ just seen, though I may be wrong in my theory as to what the phantom is.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it's gone now, at any rate,&rdquo; said Mr. Jenks, &ldquo;and I think we'd
+ better get back inside the tent. It's cold out here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Aren't some of us going to stand guard?&rdquo; demanded Mr. Damon.
+ </p>
+ <p>
+ &ldquo;What for?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Why&mdash;er&mdash;bless my key-ring! Suppose that ghost takes a notion
+ to come down here, and use his gun, as he did on the miners?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe that will happen,&rdquo; remarked Tom. &ldquo;The diamond makers, if
+ the white thing had anything to do with them, have given us a warning, and
+ I think they'll at least wait until morning to see how we heed it.&rdquo;
+ </p>
+ <p>
+ &ldquo;We aren't going to heed it!&rdquo; burst out Mr. Jenks. &ldquo;I'm going to go right
+ ahead and find that cave where they make diamonds!&rdquo;
+ </p>
+ <p>
+ &ldquo;And we're with you!&rdquo; exclaimed Tom. &ldquo;We'll have a good fire going the
+ rest of the night, and that may keep intruders away. In the morning we'll
+ begin our search, and we'll go up the trail where we saw the white
+ figure.&rdquo;
+ </p>
+ <p>
+ A big pile of wood had been collected for the fire, and Tom now piled some
+ logs and branches on the blaze. It would last for some time now, and the
+ adventurers, still talking of the &ldquo;ghost&rdquo; went back into the tent. It was
+ over an hour before they all got to sleep again, and Mr. Jenks and Mr.
+ Damon took turns in getting up once or twice during the remainder of the
+ night to replenish the fire.
+ </p>
+ <p>
+ Morning dawned without anything further having occurred to disturb them,
+ and, after a hearty breakfast, to which Tom added some fish he caught in a
+ nearby mountain stream, they set off up the trail on Phantom Mountain.
+ </p>
+ <p>
+ They had left their tent standing, as they proposed making that spot their
+ headquarters until they located the cave they were seeking. What their
+ course would be after that would depend on the circumstances.
+ </p>
+ <p>
+ If they had expected to have an easy task locating the cavern in which Mr.
+ Jenks had seen diamonds made, the adventurers were disappointed. All that
+ day they tramped up and down the mountain, looking for some secret
+ entrance, but none was disclosed. The higher they went up the great peak,
+ the fainter became the trail, until, at length it vanished completely.
+ </p>
+ <p>
+ But this was not to be wondered at, since it was on solid rock, in which
+ no footsteps would leave an impression.
+ </p>
+ <p>
+ &ldquo;They never brought you up here in a wagon, Mr. Jenks,&rdquo; decided Tom, when
+ he saw how steep the place was.
+ </p>
+ <p>
+ &ldquo;I'm inclined to think so myself,&rdquo; admitted the diamond man. &ldquo;They must
+ have reached the cave from some other way. As a matter of fact, I walked
+ some distance after getting out of the vehicle, before we got to the
+ cavern. But, even at that, I don't believe we came this way.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yet the phantom was here,&rdquo; persisted Tom, &ldquo;and I'm convinced that the
+ cave is in this neighborhood. It's up to us to find it!&rdquo;
+ </p>
+ <p>
+ But they searched the remainder of that day in vain, and as night was
+ coming on, they made their way back to the camp. As Tom, who was in the
+ lead, approached the tent, he saw something black fastened to the
+ entrance.
+ </p>
+ <p>
+ &ldquo;Hello!&rdquo; he cried. &ldquo;Some one's been here. That wasn't on the tent when we
+ left this morning.&rdquo;
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;A black piece of paper, written on with white ink,&rdquo; replied the lad. He
+ was reading it, and, as he perused it a look of surprise came over his
+ face.
+ </p>
+ <p>
+ &ldquo;Listen to this!&rdquo; called Tom. &ldquo;It's evidently from the diamond makers.&rdquo;
+ </p>
+ <p>
+ Holding up the black paper, on which the white writing stood out in bold
+ relief Tom read aloud:
+ </p>
+ <p>
+ &ldquo;Be warned in time! Go back before it is too late! You are near to death!
+ Go back!&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my shoelaces!&rdquo; cried Mr. Damon. &ldquo;This is getting serious.&rdquo;
+ </p>

+ <h2>
+ CHAPTER XV&mdash;THE LANDSLIDE
+ </h2>
+ <p>
+ Gathered about the young inventor, the three men looked at the warning.
+ The writing was poor, and it was evident that an attempt had been made to
+ disguise it. But there was no misspelling of words, and there were no
+ rudely drawn daggers, or bloody hands or anything of that sort. In fact,
+ it was a very business-like sort of warning.
+ </p>
+ <p>
+ &ldquo;Rather odd,&rdquo; commented Mr. Jenks. &ldquo;Black paper and white ink.&rdquo;
+ </p>
+ <p>
+ &ldquo;White ink is easy enough to make,&rdquo; stated Mr. Parker. &ldquo;I fancy they
+ wanted it as conspicuous as possible.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes,&rdquo; agreed Tom, &ldquo;and this warning, together with the antics of the
+ thing in white last night, shows that they are aware of our presence here,
+ and perhaps know who we are. We will have to be on our guard.&rdquo;
+ </p>
+ <p>
+ &ldquo;Do you think that fellow Munson, whom we left in the forest, could have
+ gotten here and warned them?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;It's possible,&rdquo; admitted Tom, &ldquo;but now let's see if the person who pinned
+ this warning on our tent took any of our things.&rdquo;
+ </p>
+ <p>
+ A hasty examination, however, showed that nothing had been disturbed, and
+ Tom and Mr. Damon were soon getting supper ready, everyone talking, during
+ the progress of the meal, about the events of the day, and the rather
+ weird culmination of it.
+ </p>
+ <p>
+ &ldquo;Well, we haven't had a great deal of success&mdash;so far,&rdquo; admitted Tom,
+ as they sat about the fire, in the fast gathering dusk. &ldquo;I think, perhaps,
+ we'd better try on the other side of the mountain to-morrow. We've
+ explored this side pretty thoroughly.&rdquo;
+ </p>
+ <p>
+ &ldquo;Good idea,&rdquo; commented Mr. Jenks. &ldquo;We'll do it, and move our camp. I only
+ hope those fellows don't find our airship and destroy it. We'll have a
+ hard time getting back to civilization again, if we have to walk all the
+ way.&rdquo;
+ </p>
+ <p>
+ This contingency caused Tom some uneasiness. He did not like to think that
+ the unscrupulous men might damage the Red Cloud, that had been built only
+ after hard labor. But he knew he could accomplish nothing by worrying, and
+ he tried to dismiss the matter from his mind.
+ </p>
+ <p>
+ They rather expected to see the thing in white again that night, but it
+ did not appear, and morning came without anything having disturbed their
+ heavy sleep, for they were tired from the day's tramp.
+ </p>
+ <p>
+ It took them the greater part of the day to make a circuit of the base of
+ Phantom Mountain in order to get to a place where a sort of trail led
+ upward.
+ </p>
+ <p>
+ &ldquo;It's too late to do anything to-night,&rdquo; decided Tom, as they set up the
+ tent. &ldquo;We'll rest, and start the first thing in the morning.&rdquo;
+ </p>
+ <p>
+ &ldquo;And the ghost isn't likely to find us here,&rdquo; added Mr. Damon. &ldquo;Where are
+ you going, Mr. Parker?&rdquo; he asked, as he saw the scientist tramping a
+ little way up the side of the mountain.
+ </p>
+ <p>
+ &ldquo;I am going to make some observations,&rdquo; was the answer, and no one paid
+ any more attention to him for some time. Supper was nearly ready when Mr.
+ Parker returned. His face wore a rather serious air, and Mr. Damon, noting
+ it, asked laughingly:
+ </p>
+ <p>
+ &ldquo;Well, did you discover any volcanoes, that may erupt during the night,
+ and scare us to death?&rdquo;
+ </p>
+ <p>
+ &ldquo;No,&rdquo; replied Mr. Parker, calmly, &ldquo;but there is every indication that we
+ will soon have a terrific electrical storm. From a high peak I caught a
+ glimpse of one working this way across the mountains.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'd better fasten the tent well down,&rdquo; called Tom. &ldquo;We don't want
+ it to blow away.&rdquo;
+ </p>
+ <p>
+ &ldquo;There will not be much danger from wind,&rdquo; was Mr. Parker's opinion.
+ </p>
+ <p>
+ &ldquo;From what then?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;From the discharges of lightning among these mountain peaks, which
+ contain so much iron ore. We will be in grave danger.&rdquo;
+ </p>
+ <p>
+ The fact that the scientist had not always made correct predictions was
+ not now considered by his hearers, and Tom and the two men gazed at Mr.
+ Parker in some alarm.
+ </p>
+ <p>
+ &ldquo;Is there anything we can do to avoid it?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;The only thing to do would be to leave the mountain,&rdquo; was the answer,
+ &ldquo;and, as the iron ore extends for miles, we can not get out of the danger
+ zone before the storm will reach us. It will be here in less than half an
+ hour.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'd better have supper,&rdquo; remarked Tom, practically, &ldquo;and get ready
+ for it. Perhaps it may not be as bad as Mr. Parker fears.&rdquo;
+ </p>
+ <p>
+ &ldquo;It will be bad enough,&rdquo; declared the gloomy scientist, and he seemed to
+ find pleasure in his announcement.
+ </p>
+ <p>
+ The meal was soon over, and Tom busied himself in looking to the guy ropes
+ of the tent, for he feared lest there might be wind with the storm. That
+ it was coming was evident, for now low mutterings of thunder could be
+ heard off toward the west.
+ </p>
+ <p>
+ Black clouds rapidly obscured the heavens, and the sound of thunder
+ increased. Fitful flashes of lightning could be seen forking across the
+ sky in jagged chains of purple light.
+ </p>
+ <p>
+ &ldquo;It's going to be a heavy storm,&rdquo; Tom admitted to himself. &ldquo;I hope
+ lightning doesn't strike around here.&rdquo;
+ </p>
+ <p>
+ The storm came on rapidly, but there was a curious quietness in the air
+ that was more alarming than if a wind had blown. The campfire burned
+ steadily, and there was a certain oppressiveness in the atmosphere.
+ </p>
+ <p>
+ It was now quite dark, save when the fitful lightning flashes came, and
+ they illuminated the scene brilliantly for a few seconds. Then, by
+ contrast, it was blacker than ever.
+ </p>
+ <p>
+ Suddenly, as Tom was gazing up toward the peak of Phantom Mountain, he saw
+ something that caused him to cry out in alarm. He pointed upward, and
+ whispered hoarsely:
+ </p>
+ <p>
+ &ldquo;The ghost again! There's our friend in white!&rdquo;
+ </p>
+ <p>
+ The others looked, and saw the same weird figure that had menaced them
+ when they were encamped on the other side of the peak.
+ </p>
+ <p>
+ &ldquo;They must have followed us,&rdquo; said Mr. Jenks, in a low voice.
+ </p>
+ <p>
+ Slowly the figure advanced, It waved the long white arms, as if in
+ warning. At times it would be only dimly visible in the blackness, then,
+ suddenly it would stand out in bold relief as a great flash of fire split
+ the clouds.
+ </p>
+ <p>
+ The thunder, meanwhile, had been growing louder and sharper, indicating
+ the nearer approach of the storm. Each lightning flash was followed in a
+ second or two, by a terrific clap. Still there was no wind nor rain, and
+ the campfire burned steadily.
+ </p>
+ <p>
+ All at once there was a crash as if the very mountain had split asunder,
+ and the adventurers saw a great ball of purple-bluish fire shoot down, as
+ if from some cloud, and strike against the side of the crag, not a hundred
+ feet from where stood the ghostly figure in white.
+ </p>
+ <p>
+ &ldquo;That was a bad one,&rdquo; cried Mr. Damon, shouting so as to be heard above
+ the echoes of the thunderclap.
+ </p>
+ <p>
+ Almost as he spoke there came another explosion, even louder than the one
+ preceding. A great ball of fire, pear shaped, leaped for the same spot in
+ the mountain.
+ </p>
+ <p>
+ &ldquo;There's a mass of iron ore there!&rdquo; yelled Mr. Parker. &ldquo;The lightning is
+ attracted to it!&rdquo;
+ </p>
+ <p>
+ His voice was swallowed up in the terrific crash that followed, and, as
+ there came another flash of the celestial fire, the figure in white could
+ be seen hurrying back up the mountain trail. Evidently the electrical
+ storm, with lightning bolts discharging so close, was too much for the
+ &ldquo;ghost.&rdquo;
+ </p>
+ <p>
+ In another instant it looked as if the whole place about where the diamond
+ seekers stood, was a mass of fire. Great forked tongues of lightning
+ leaped from the clouds, and seemed to lick the ground. There was a rattle
+ and bang of thunder, like the firing of a battery of guns. Tom and the
+ others felt themselves tingling all over, as if they had hold of an
+ electrical battery, and there was a strong smell of sulphur in the air.
+ </p>
+ <p>
+ &ldquo;We are in the midst of the storm!&rdquo; cried Mr. Parker. &ldquo;We are standing on
+ a mass of iron ore! Any minute may be our last!&rdquo;
+ </p>
+ <p>
+ But fate had not intended the adventurers for death by lightning. Almost
+ as suddenly as it had begun, the discharge of the tongues of fire ceased
+ in the immediate vicinity of our friends. They stood still&mdash;awed&mdash;not
+ knowing what to do.
+ </p>
+ <p>
+ Then, once more, came a terrific clap! A great mass of fire, like some
+ red-hot ingot from a foundry, was hurled through the air, straight at the
+ face of the mountain, and at the spot where the figure in white had stood
+ but a few minutes before.
+ </p>
+ <p>
+ Instantly the earth trembled, as it had at Earthquake Island, but it was
+ not the same. It was over in a few seconds. Then, as the diamond seekers
+ looked, they saw in the glare of a score of lightning flashes that
+ followed the one great clap, the whole side of the mountain slip away, and
+ go crashing into the valley below.
+ </p>
+ <p>
+ &ldquo;A landslide!&rdquo; cried Mr. Parker. &ldquo;That is the landslide which I predicted!
+ The lightning bolt has split Phantom Mountain!&rdquo;

+ <h2>
+ CHAPTER XVI&mdash;THE VAST CAVERN
+ </h2>
+ <p>
+ For a time the roiling, slipping, sliding and tumbling of the mass of
+ earth and stones, down the side of the mountain, effectually drowned all
+ other sounds. Even the thunder was stilled, and though Tom and his
+ companions called to one another in terror, their voices could not rise
+ above that terrific tumult.
+ </p>
+ <p>
+ Finally, when they found that the direction of the slide was away from
+ their tent, and that they were not likely to be engulfed, they grew more
+ calm.
+ </p>
+ <p>
+ Gradually the noise subsided. The great boulders had rolled to the bottom
+ of the valley, and now only a mass of earth and stones was sliding down.
+ Even this stopped in about five minutes, and, as though satisfied with
+ what it had done, the electrical storm passed. Not a drop of rain had
+ fallen.
+ </p>
+ <p>
+ &ldquo;Bless my shirt studs!&rdquo; exclaimed Mr. Damon, who was the first to speak
+ after the din had quieted. &ldquo;Bless my soul! But that was awful!&rdquo;
+ </p>
+ <p>
+ &ldquo;It was just what I expected,&rdquo; said Mr. Parker, calmly. &ldquo;I knew, from my
+ observations, that we were in a region where landslides and terrific
+ electrical storms may be expected at any time. I fully looked for this.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked Mr. Jenks, rather sarcastically, &ldquo;I hope it came up to
+ your expectations, Mr. Parker.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, fully,&rdquo; was the answer, &ldquo;though I wish it could have happened in
+ daylight, so that I could better have observed certain phenomena regarding
+ the landslide. They are very interesting.&rdquo;
+ </p>
+ <p>
+ &ldquo;At a distance,&rdquo; admitted Tom, with a laugh of relief. &ldquo;Well, I'm glad
+ it's over, though we'll have to wait until morning to see what damage has
+ been done. Lucky we weren't struck by lightning. I never saw such bolts!&rdquo;
+ </p>
+ <p>
+ &ldquo;Me, either!&rdquo; declared Mr. Damon. &ldquo;This mountain seems to attract them.&rdquo;
+ </p>
+ <p>
+ &ldquo;It is like a magnet,&rdquo; said Mr. Parker. &ldquo;I think I shall be able to make
+ some fine observations here.&rdquo;
+ </p>
+ <p>
+ &ldquo;If we live through it,&rdquo; murmured Mr. Jenks.
+ </p>
+ <p>
+ They watched the play of lightning about a distant bank of clouds, but the
+ storm was now far away, only a faint rumbling of thunder being heard.
+ </p>
+ <p>
+ &ldquo;I'm wondering what happened to the phantom,&rdquo; said Tom, after a pause.
+ &ldquo;Seems to me he was right in that track of the storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;Do you think it was a 'he'?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I think we'll find that it's some sort of a man,&rdquo; answered the young
+ inventor. &ldquo;We may find out very soon, now. I've changed my theory about
+ the ghost being reflections of light.&rdquo;
+ </p>
+ <p>
+ &ldquo;How's that?&rdquo; Mr. Damon wanted to know.
+ </p>
+ <p>
+ &ldquo;Well, I think we are on the side of Phantom Mountain where the diamond
+ cave is,&rdquo; went on the lad. &ldquo;The fact that the phantom appeared here, soon
+ after we arrived, shows that the men kept close track of our movements. It
+ also shows, I think, that the phantom did not have to travel far to be on
+ the spot, whereas we had to make quite a trip to get around the base of
+ the mountain. I think the cave is up there,&rdquo; and Tom pointed toward the
+ spot where the weird figure had been last seen, before the storm drove it
+ back.
+ </p>
+ <p>
+ &ldquo;There may be two phantoms,&rdquo; suggested Mr. Jenks. &ldquo;They may keep one on
+ this side of the mountain, and one on the other, to warn intruders away.
+ </p>
+ <p>
+ &ldquo;It's possible,&rdquo; admitted Tom. &ldquo;Well, we'll see how things look in the
+ morning, when we'll take up our march again, and go up the mountain. We'll
+ reach the top, if possible, which we couldn't do from the other side, as
+ it was too steep.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope we shall be able to go forward in the morning,&rdquo; came from Mr.
+ Jenks.
+ </p>
+ <p>
+ &ldquo;What do you mean?&rdquo; asked the lad, struck by a peculiar significance in
+ the diamond man's tones.
+ </p>
+ <p>
+ &ldquo;Why, that landslide may have opened a great gully in the side of Phantom
+ Mountain, which will prevent us from passing. It was a terrific lot of
+ earth and stones that slid away,&rdquo; answered Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;It certainly was,&rdquo; agreed Mr. Parker. &ldquo;I would not be surprised if the
+ mountain was half destroyed, and it may be that the diamond cave no longer
+ exists.&rdquo;
+ </p>
+ <p>
+ &ldquo;Not very cheerful, to say the least,&rdquo; murmured Mr. Jenks to Tom, and, as
+ it was getting quite chilly, following the storm, they went inside the
+ tent.
+ </p>
+ <p>
+ Tom could hardly wait for daylight, to get up and see what havoc the
+ landslide had wrought. As soon as the first faint flush of dawn showed
+ over the eastern peaks, he hurried from the tent. Mr. Damon heard him
+ arise, and followed.
+ </p>
+ <p>
+ A curious scene met their eyes. All about were great rocks rent and torn
+ by the awful power of the lightning. The fronts of the stone cliffs were
+ scarred and burned by the electrical fire, and fantastic markings,
+ grotesque faces, and leering animals seemed to have been drawn by some
+ gigantic artist who used a bolt from heaven for his brush.
+ </p>
+ <p>
+ But the eyes of Tom and Mr. Damon took all this in at a glance, and then
+ their gaze went forward to where the avalanche had torn away a great part
+ of the mountain.
+ </p>
+ <p>
+ &ldquo;Whew! I should say it was a landslide!&rdquo; cried Tom.
+ </p>
+ <p>
+ &ldquo;Bless my wishbone, yes!&rdquo; agreed Mr. Damon.
+ </p>
+ <p>
+ Below them, in the valley, lay piled immense masses of earth and stones.
+ Boulders were heaped up on boulders, and rocks upon rocks, being tossed
+ about in heaps, strung about in long ridges, and swirled about in curves,
+ as though some cyclone had toyed with them after the lightning flash had
+ tossed them there.
+ </p>
+ <p>
+ &ldquo;But the mountain isn't half gone,&rdquo; said Tom, as his eyes took in what was
+ left of the phantom berg. &ldquo;I guess it will take a few more bolts like that
+ one, to put this hill out of business.&rdquo;
+ </p>
+ <p>
+ Though the landslide had been a great one, the larger part of the mountain
+ still stood. An immense slice had been taken from one side, but the summit
+ was untouched.
+ </p>
+ <p>
+ &ldquo;And there's where the diamond cave is!&rdquo; cried Tom, pointing to it.
+ </p>
+ <p>
+ &ldquo;I think so myself,&rdquo; agreed Mr. Jenks, who came from the tent at that
+ moment, and joined the lad and Mr. Damon. &ldquo;I think we shall find the cave
+ somewhere up there. We must start for it, as soon as we have eaten, and we
+ may reach it by night.&rdquo;
+ </p>
+ <p>
+ The three stood gazing up toward the summit of the great mountain.
+ Suddenly, as the sun rose higher in the heavens, it sent a shaft of rosy
+ light on the face of the berg that had been scarred by the landslide. Tom
+ Swift uttered an exclamation, and pointed at something.
+ </p>
+ <p>
+ &ldquo;See!&rdquo; he cried. &ldquo;Look where the trail is&mdash;the trail down which the
+ phantom must have come. It is on the edge of a cliff now!&rdquo;
+ </p>
+ <p>
+ They looked, and saw that this was so. The increasing light had just
+ revealed it to them. When the lightning bolt had torn away a great portion
+ of the mountain it had cut sheer down for a great depth and when the earth
+ and stones fell away they left a narrow pathway, winding around the
+ mountain, but so near the edge of a great chasm, that there was room but
+ for one person at a time to walk on that footway. The uncertain trail up
+ Phantom Mountain had all but been destroyed.
+ </p>
+ <p>
+ &ldquo;The way up to the peak is by that path, now,&rdquo; spoke Tom, in a low voice.
+ </p>
+ <p>
+ &ldquo;Bless my soul!&rdquo; cried Mr. Damon. &ldquo;It's as much as a man's life is worth
+ to attempt it. If he got dizzy, he'd topple over, and fall a thousand
+ feet. Dare we risk it?&rdquo;
+ </p>
+ <p>
+ &ldquo;It's the only way to get up,&rdquo; went on Tom. &ldquo;It's either that way, or not
+ at all. We've tried the other side without success. We must go up this way&mdash;or
+ turn back.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'll go up!&rdquo; cried Mr. Jenks. &ldquo;It may not be as dangerous as it
+ looks from here.&rdquo;
+ </p>
+ <p>
+ But it was even more dangerous than it appeared, when they went part way
+ up it after a hasty breakfast. The trail was a mere ledge of rock now, and
+ in some places, to get around a projecting edge of the mountain, they had
+ to stand with their backs to the dizzy depths at their feet, and with both
+ arms outstretched work their way around to where the trail was wider.
+ </p>
+ <p>
+ &ldquo;Shall we risk it?&rdquo; asked Tom, when they had tried the way, and found it
+ so dangerous. &ldquo;We can't take anything with us&mdash;even our guns, for we
+ couldn't carry them, and if we reach the mouth of the cave, and find those
+ men there&mdash;&rdquo;
+ </p>
+ <p>
+ He paused significantly. The adventurers looked at one another. The search
+ for the diamond makers was becoming more and more dangerous.
+ </p>
+ <p>
+ &ldquo;I say let's go on!&rdquo; decided Mr. Damon, suddenly. &ldquo;We want to locate that
+ cave, first of all. Perhaps, when we do find it, we may see some easier
+ way of getting to it than this. And if those diamond makers do attack us&mdash;well,
+ I don't believe they'll shoot defenseless men, and they may listen to
+ reason, and give Mr. Jenks his rights&mdash;tell him how to make diamonds
+ in return for the money he gave them.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe those scoundrels will listen to reason,&rdquo; replied the
+ diamond man, &ldquo;but I agree with Mr. Damon that we ought to go on. We may
+ find some other means of reaching the cave&mdash;if we can discover it,
+ and we'll take a chance with the men.&rdquo;
+ </p>
+ <p>
+ &ldquo;Forward it is, then!&rdquo; cried Tom. &ldquo;I have a revolver, and I can supply one
+ of you gentlemen with another. They may come in useful in an emergency.
+ Let's go back to camp, take a little lunch in our pockets, and try to
+ scale the mountain.&rdquo;
+ </p>
+ <p>
+ They were soon on their way up the dizzy path once more, and, as they
+ advanced, they found it growing more and more dangerous. In some places
+ they found it almost impossible to get around certain corners, where there
+ was barely room for their feet. As Tom remarked grimly, a fat man never
+ could have done it. Fortunately they were all comparatively thin, for
+ their hard work, and not too abundant food, since they had left the
+ airship, had reduced their weight.
+ </p>
+ <p>
+ Up and up they went, higher and higher, sometimes finding the path wide
+ enough for two to walk abreast, and again seeing it narrow almost to a
+ ribbon. They hardly dared look down into the chasm at their left&mdash;a
+ chasm filled, in part, with the rocks and boulders tossed into it by the
+ lightning bolt.
+ </p>
+ <p>
+ Tom was in the lead, and had just made a dangerous turn around a shoulder
+ of rock&mdash;one of those places where he had to extend both arms, and
+ fairly hug the cliff before he could get around.
+ </p>
+ <p>
+ But, when he had made it, and found himself on a broad pathway, cut in the
+ living rock, he gave a great shout&mdash;a shout that caused his
+ companions to hasten to his side. They found the young inventor pointing
+ to a clump of bushes and small trees.
+ </p>
+ <p>
+ But it was not the shrubbery that Tom desired to call to their attention.
+ They saw that in an instant, for, dimly seen through the leaves, was
+ something black, and, as they looked more closely, they saw that it was a
+ great hole in the side of the mountain&mdash;a vast cavern, opening like a
+ tunnel.
+ </p>
+ <p>
+ &ldquo;The cave! The cave!&rdquo; cried Tom. &ldquo;The diamond makers' cave!&rdquo;
+ </p>
+ <p>
+ Hardly had he spoken than two men, each one carrying a gun, showed
+ themselves in the mouth of the cavern, and, instant later they both ran
+ toward the little party of adventurers.

+ <h2>
+ CHAPTER XVII&mdash;THE PHANTOM CAPTURED
+ </h2>
+ <p>
+ Surprise held Tom and his friends almost spellbound for the moment. The
+ young inventor's hand went toward the pocket where he carried his
+ revolver. Mr. Jenks, who had the only other weapon, sought to draw it, but
+ he was stopped by a gesture of one of the two men with guns.
+ </p>
+ <p>
+ &ldquo;Hold on, strangers!&rdquo; the man cried. &ldquo;I know what you're up to! Better not
+ try to draw anything&mdash;it might not be healthy. Now, then, who are
+ you, and what do you want?&rdquo;
+ </p>
+ <p>
+ The question came rather as a surprise, at least to Tom and Mr. Jenks.
+ They had taken it for granted that these men&mdash;if they were the
+ diamond makers&mdash;would know Mr. Jenks, and guess at his errand in
+ coming back to Phantom Mountain. But, it seemed, that they took them all
+ for casual strangers.
+ </p>
+ <p>
+ No one answered for a moment. Tom caught the eye of Mr. Jenks, and there
+ was a look of hope in it. If ever there was a time for strategy, it was
+ now. Evidently Munson, the stowaway on the airship, had not yet been able
+ to send a warning to his confederates. And neither of the two men
+ recognized Mr. Jenks as the man who had been defrauded of his rights. It
+ might be possible to conceal the real object of the adventurers until they
+ had time to formulate a plan of action.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; exclaimed the man with the gun, impatiently, &ldquo;I ask you folks a
+ question. What do you want?&rdquo;
+ </p>
+ <p>
+ Fortunately, neither Mr. Damon nor Mr. Parker replied. The former because
+ he deferred to Tom and Mr. Jenks, and the scientist because he was busy
+ inspecting some curious rocks he picked up. As it turned out this was the
+ luckiest thing he could have done. It lent color to what Mr. Jenks said a
+ moment later.
+ </p>
+ <p>
+ &ldquo;What are you doing up here?&rdquo; demanded the man again. &ldquo;Don't you know this
+ is private property?&rdquo;
+ </p>
+ <p>
+ &ldquo;We&mdash;we were just looking around,&rdquo; answered Mr. Jenks, which was true
+ enough; as far as it went.
+ </p>
+ <p>
+ &ldquo;Prospecting,&rdquo; added Tom.
+ </p>
+ <p>
+ &ldquo;After gold?&rdquo; demanded the second man, suspiciously.
+ </p>
+ <p>
+ &ldquo;We'd be glad to find some,&rdquo; retorted the lad. At that moment Mr. Parker
+ began breaking off bits of rock with a small geologist's hammer which he
+ carried. The men with the guns looked at him.
+ </p>
+ <p>
+ &ldquo;So you think you'll find gold up here?&rdquo; asked the one who had first
+ spoken.
+ </p>
+ <p>
+ &ldquo;Is there any?&rdquo; inquired Tom, trying to make his voice sound eager.
+ </p>
+ <p>
+ &ldquo;Nary a bit, strangers,&rdquo; was the answer, and the two men laughed heartily.
+ &ldquo;Now, we don't want to seem harsh,&rdquo; went on the man who seemed to be the
+ spokesman, &ldquo;but you'd better get away from here. This is private ground,
+ and dangerous too&mdash;how'd you ever get up the trail&mdash;we heard it
+ was destroyed.&rdquo;
+ </p>
+ <p>
+ &ldquo;There is still a narrow path,&rdquo; said Mr. Jenks. &ldquo;We came up that&mdash;the
+ lightning and landslide haven't left much of it, though.&rdquo;
+ </p>
+ <p>
+ Mr. Parker looked quickly up from the rocks at which he was tapping with
+ his small hammer. &ldquo;You have terrific lightning up here,&rdquo; he said. &ldquo;I am
+ much interested in it, from a scientific standpoint. I predict that some
+ day the entire mountain will be destroyed by a blast from the sky.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope it won't be right away,&rdquo; spoke one of the men. &ldquo;Now I guess you
+ folks had better be leaving while there's a path left to go down by.&rdquo;
+ </p>
+ <p>
+ &ldquo;Might I ask,&rdquo; broke in Mr. Parker, as calmly as though he was lecturing
+ to a class of students, &ldquo;might I ask if you have noticed any peculiar
+ effect of the lightning up here on the summit of the mountain? Does it
+ fuse and melt rocks, so to speak?&rdquo;
+ </p>
+ <p>
+ &ldquo;What's that?&rdquo; cried the spokesman, with a sudden flash of anger. The two
+ men looked at each other.
+ </p>
+ <p>
+ &ldquo;I wanted to know, merely for scientific reasons, whether the lightning up
+ here ever melted rocks?&rdquo; repeated Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Well, whether it's for scientific reasons or for any other, I'm not going
+ to answer you!&rdquo; snapped the man. &ldquo;It's none of your affair what the
+ lightning does up here. Now you'd all better 'vamoose'&mdash;clear out!&rdquo;
+ </p>
+ <p>
+ &ldquo;All right&mdash;we'll go,&rdquo; said Tom, quickly, at the same time motioning
+ to Mr. Jenks to agree with him. The eyes of the young inventor were roving
+ about. He saw what looked like a second trail, leading down the mountain,
+ from the far side of the cave. He was convinced now that there was another
+ way to get to it. Possibly they might find it. At any rate nothing more
+ could be done now. They must go back, for the cavern was too well guarded
+ to attempt to enter it by force&mdash;at least just yet.
+ </p>
+ <p>
+ &ldquo;Yes, we'll go back,&rdquo; assented Mr. Jenks.
+ </p>
+ <p>
+ Mr. Parker was tapping away at the rocks. He looked toward the black mouth
+ of the big cave. On what corresponded to the roof of it, some distance
+ back from the entrance, he saw a slender metal rod sticking up into the
+ air.
+ </p>
+ <p>
+ &ldquo;May I ask if that's a lightning rod?&rdquo; he inquired innocently. &ldquo;If it is,
+ I should like to ask about its action in a mountain that is so impregnated
+ with iron ore.
+ </p>
+ <p>
+ &ldquo;You may ask until you get tired!&rdquo; cried the spokesman, again showing
+ unreasoning anger, &ldquo;but you'll get no answer from us. Now get away from
+ here before we do something desperate. You're on private ground and you're
+ not wanted. Clear out while you have the chance.&rdquo;
+ </p>
+ <p>
+ There was no help for it. Slowly our friends turned and began to go down
+ the dangerous trail. They were soon out of sight of the two men who stood
+ before the cave, with their guns ready, but neither Tom nor any of his
+ companions spoke for some time.
+ </p>
+ <p>
+ When they had rounded one of the most dangerous turns the young inventor
+ sat down to rest, an example followed by the others.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; asked Tom, &ldquo;do you think those are some of the diamond makers, Mr.
+ Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I certainly do, though I never saw those two men before. If I could once
+ get inside the cave, I could tell whether or not it was the one where I
+ was practically held a prisoner. But I'm sure it is. I know some of the
+ men used to go off every day with guns, and not come back until night. I
+ have no doubt they were on guard, just as these two are. And, also, I
+ think I heard them speak of a second entrance to the cavern. The one we
+ just saw may not be the main one, through which I was taken.&rdquo;
+ </p>
+ <p>
+ &ldquo;I believe we are on the right track,&rdquo; ventured Mr. Damon, &ldquo;but we will
+ either have to go up there after dark, which will be risky, on account of
+ the narrow trail, or else we will have to find some other path.&rdquo;
+ </p>
+ <p>
+ &ldquo;The last would be better,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;That rod of metal sticking up on top of the cave interested me,&rdquo; said the
+ scientist. &ldquo;Did you hear anything of that when you were here before, Mr.
+ Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;No. Probably that is only a lightning rod, or it may be a staff for a
+ signal flag. But what surprises me is that those men didn't suspect that
+ we were seeking to discover their secret. They took us for ordinary
+ prospectors.&rdquo;
+ </p>
+ <p>
+ &ldquo;So much the better,&rdquo; remarked Tom. &ldquo;We have a chance now of getting
+ inside that cave. But we will have to go back to camp, and make other
+ plans. And we must hurry, or it will be dark before we get there.&rdquo;
+ </p>
+ <p>
+ They hastened their steps, pausing only briefly to eat some of the lunch
+ they had brought along, and to drink from a spring that bubbled from the
+ side of the mountain. It was getting dusk when they got back to their
+ tent. They found nothing disturbed.
+ </p>
+ <p>
+ &ldquo;I wonder if we'll see that phantom again to-night?&rdquo; ventured Tom, as they
+ were sitting about the campfire a little later.
+ </p>
+ <p>
+ &ldquo;Probably not,&rdquo; remarked Mr. Jenks. &ldquo;I don't believe the ghost will
+ venture down the dangerous trail after dark, and the gang may think that
+ the warning given us by the two men on guard at the cave will be
+ sufficient. But if we don't leave here by to-morrow I think we will have
+ another visit from the thing in white.&rdquo;
+ </p>
+ <p>
+ It was about an hour after this when Tom was collecting some wood in a
+ pile nearer the fire, so as to have it ready to throw on, in case there
+ was any alarm in the night, that he happened to look up toward the summit
+ of the mountain. A slight noise, as of loose stones rolling down,
+ attracted his attention, and, at first, he feared lest another landslide
+ was beginning, but a moment later he saw what caused it.
+ </p>
+ <p>
+ There, advancing down the steep and dangerous trail was the figure in
+ white&mdash;the phantom. Instantly a daring plan came into Tom's head.
+ Dropping the wood softly, he moved back out of the glare of the fire.
+ </p>
+ <p>
+ &ldquo;Mr. Jenks!&rdquo; he called in a whisper.
+ </p>
+ <p>
+ The diamond man, who was behind the tent, came toward Tom.
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; he asked. Then, as he saw the ghostly visitor, he added: &ldquo;Oh&mdash;the
+ phantom again! What's it up to?&rdquo;
+ </p>
+ <p>
+ &ldquo;The same thing,&rdquo; replied Tom, &ldquo;but it won't do it long, if my plan
+ succeeds.&rdquo;
+ </p>
+ <p>
+ &ldquo;What plan is that, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm going to try to capture that&mdash;that man&mdash;or whatever it is.
+ Will you help?&rdquo;
+ </p>
+ <p>
+ &ldquo;Surely!&rdquo;
+ </p>
+ <p>
+ &ldquo;Then let's work around behind it, while Mr. Damon and Mr. Parker come up
+ from in front. We'll solve this part of the mystery, anyhow, if it's
+ possible!&rdquo;
+ </p>
+ <p>
+ The two other men were soon told of the plan. Meanwhile the thing in white
+ had advanced slowly, until within a few hundred feet of the camp. They
+ could see now that it was no shaft of light, but some white body, shaped
+ like a tall, thin man, draped in a white garment. The long arms waved to
+ and fro. There was no semblance of a head.
+ </p>
+ <p>
+ &ldquo;You and Mr. Parker go right toward it, slowly, Mr. Damon,&rdquo; advised Tom.
+ &ldquo;Mr. Jenks and I will make a circle, and get in back. Then, if it's
+ anything alive we'll have it.&rdquo;
+ </p>
+ <p>
+ The &ldquo;ghost&rdquo; continued to advance. Tom and the diamond man stole off to one
+ side, their buckskin moccasins making no sound. Mr. Damon and the
+ scientist went boldly forward.
+ </p>
+ <p>
+ This movement appeared to disconcert the spirit. It halted, waved the arms
+ with greater vigor than before, and seemed to indicate to the adventurers
+ that it was dangerous to advance. But Mr. Damon and Mr. Parker kept on.
+ They wanted to give Tom and Mr. Jenks time enough to make the circuit.
+ </p>
+ <p>
+ Suddenly the stillness of the night was broken by a low whistle. It was
+ Tom's signal that he and Mr. Jenks were ready.
+ </p>
+ <p>
+ &ldquo;Come on! Run!&rdquo; cried Mr. Damon.
+ </p>
+ <p>
+ The scientist and the eccentric man leaped forward.
+ </p>
+ <p>
+ The &ldquo;ghost&rdquo; heard the whistle, and heard the spoken words. The thing in
+ white hesitated a moment, and then raised one arm. There was a flash of
+ fire, and a loud report.
+ </p>
+ <p>
+ &ldquo;He's firing in the air!&rdquo; cried Tom. &ldquo;Come on, we have him now!&rdquo;
+ </p>
+ <p>
+ Undaunted by the display of firearms, Mr. Damon and Mr. Parker kept on.
+ They could hear Tom and Mr. Jenks running up in back of the figure. The
+ latter also heard this, and suddenly turned. Caught between the two forces
+ of our friends, the &ldquo;ghost&rdquo; was at a loss what to do.
+ </p>
+ <p>
+ The next instant Tom, who had distanced Mr. Jenks, made a flying tackle
+ for the figure in white, and caught it around the legs. Very substantial
+ legs they were, too, Tom felt&mdash;the legs of a man.
+ </p>
+ <p>
+ &ldquo;Wow!&rdquo; yelled the &ldquo;ghost,&rdquo; as he went down in a heap, the revolver falling
+ from his hand.
+ </p>
+ <p>
+ &ldquo;Come on!&rdquo; cried Tom. &ldquo;I have him!&rdquo;
+ </p>
+ <p>
+ His friends rushed to his aid. There was a confused mass of dark bodies,
+ arms and legs mingled with something tall and thin, all in white. Suddenly
+ the moon came from behind a cloud and they could see what they had
+ captured&mdash;for captured the phantom was.
+ </p>
+ <p>
+ It proved to be a rather small man, who wore upon his shoulders a
+ framework of wood, over which some white cloth was draped. It had fallen
+ off him when Tom made that tackle.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked the young inventor, as he sat on the struggling man's
+ chest. &ldquo;I guess we've got you.&rdquo;
+ </p>
+ <p>
+ &ldquo;I rather guess you have, stranger,&rdquo; was the cool reply.

+ <h2>
+ CHAPTER XVIII&mdash;BILL RENSHAW WILL HELP
+ </h2>
+ <p>
+ They were all panting from the exertion of the run up the mountain and the
+ contest with the phantom&mdash;a phantom no longer&mdash;though, truth to
+ tell, the struggle was not nearly so fierce as Tom had expected. He
+ thought the &ldquo;ghost&rdquo; would put up a stiff fight.
+ </p>
+ <p>
+ &ldquo;Got any ropes to tie him with?&rdquo; asked Mr. Damon, who was helping Tom hold
+ the man down.
+ </p>
+ <p>
+ &ldquo;Ropes? You aren't going to tie me up are you, strangers?&rdquo; asked the
+ captive.
+ </p>
+ <p>
+ &ldquo;That's what we are!&rdquo; exclaimed Mr. Jenks. &ldquo;We've had trouble enough in
+ this matter, and if I've got one of the gang, perhaps I can get some of
+ the others, and have my rights. So tie him up, Tom, and we'll take him to
+ camp.
+ </p>
+ <p>
+ &ldquo;Oh, you needn't go to all that trouble, strangers,&rdquo; went on the man,
+ calmly. &ldquo;If one of you will get off my chest, and the other gentleman ease
+ up on my stomach a bit, I'll walk wherever you want me, and not make any
+ trouble. I haven't got a gun.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my gloves! But you're a cool one,&rdquo; commented Mr. Damon, as he
+ complied with the man's request, and got up from his stomach. &ldquo;But look
+ out for him, Tom. He had a gun, for he fired it in the air.&rdquo;
+ </p>
+ <p>
+ &ldquo;He hasn't it now,&rdquo; answered the young inventor. &ldquo;I knocked it from his
+ hand when I leaped for him.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's what you did,&rdquo; assented the man, as he got up, while Tom kept a
+ tight hold of him, as did Mr. Jenks. &ldquo;What kind of a grizzly bear hug do
+ you call that, anyhow, that you gave me?&rdquo;
+ </p>
+ <p>
+ &ldquo;That was a football tackle,&rdquo; explained Tom.
+ </p>
+ <p>
+ &ldquo;I allers heard that was a dangerous game!&rdquo; remarked the former phantom
+ simply. &ldquo;Well, now you've got me, what are you going to do with me?&rdquo;
+ </p>
+ <p>
+ &ldquo;Take you where we can have a good look at you,&rdquo; replied Mr. Jenks, as he
+ kicked aside the wooden framework, and the sheet which had made the
+ &ldquo;ghost&rdquo; appear so tall. &ldquo;So this is how you worked it; eh?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yep. That was the 'haunt' stranger. I made it myself, and it worked all
+ right until you folks come along. I rather suspicioned from the first,
+ when I played the trick over on 'tother side of the mountain, that you
+ wouldn't be so easy to fool as most prospectors are.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, so you're the only ghost then?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I'm the only one.&rdquo;
+ </p>
+ <p>
+ By this time they had reached the camp. Tom threw some light logs on the
+ fire, which blazed up brightly. As the flames illuminated the face of
+ their captive, Mr. Jenks looked at him, and cried out:
+ </p>
+ <p>
+ &ldquo;Why it's Bill Renshaw!&rdquo;
+ </p>
+ <p>
+ &ldquo;That's me,&rdquo; admitted the man who had played the part of the phantom, &ldquo;and
+ thunder-turtles! if it ain't Mr. Jenks who was once in the diamond cave
+ with us. Whatever happened to you? I never heard. The others said you got
+ tired and went away.&rdquo;
+ </p>
+ <p>
+ &ldquo;They took me away&mdash;defrauded me of my rights!&rdquo; declared Mr. Jenks,
+ bitterly. &ldquo;But I'll get them back! To think of Bill Renshaw playing the
+ part of a ghost!&rdquo;
+ </p>
+ <p>
+ &ldquo;They made me do it,&rdquo; went on the man, somewhat dejectedly. &ldquo;I wanted to
+ be at work in the cave, but they wouldn't let me.&rdquo;
+ </p>
+ <p>
+ &ldquo;Is this man one of the diamond makers?&rdquo; asked Tom, in great surprise.
+ </p>
+ <p>
+ &ldquo;He is&mdash;one of the helpers, though I don't believe he knows the
+ secret of making the gems,&rdquo; explained Mr. Jenks. &ldquo;He was one of the men in
+ the cave when I was there before, and he and I struck up quite a
+ friendship; didn't we, Renshaw?&rdquo;
+ </p>
+ <p>
+ &ldquo;That's what, and there ain't no reason why we can't be friends now; that
+ is unless you hold a grudge against me for firing at you. But I only shot
+ in the air, to scare you away. Them's my instructions. I'm supposed to be
+ on guard, and scare away strangers. I'm tired of the work, too, for I
+ don't get my share, and those other fellows, in the cave, get all the
+ money from the diamonds.&rdquo;
+ </p>
+ <p>
+ Tom Swift uttered an exclamation. A sudden plan had come to him. Quickly
+ he whispered to Mr. Jenks:
+ </p>
+ <p>
+ &ldquo;Make a friend of this man if possible. He evidently is dissatisfied.
+ Offer him a sum to show us another way into the cave, and we may yet
+ discover the secret of the diamond makers.&rdquo;
+ </p>
+ <p>
+ &ldquo;I will,&rdquo; declared Mr. Jenks, quietly. Then, turning to Renshaw, he added:
+ </p>
+ <p>
+ &ldquo;Bill, come over here. I want to have a talk with you. Perhaps it will be
+ to our mutual advantage.&rdquo;
+ </p>
+ <p>
+ He led the former phantom to one side, and for some time conversed
+ earnestly with him. Mr. Jenks told the story of how he had been deceived
+ by Folwell and the others who were at the head of the gang of diamond
+ makers. The rich man related how they had taken his money, and, after
+ promising to disclose the secret process to him, had broken faith, and had
+ drugged him, afterward taking him out of the cave.
+ </p>
+ <p>
+ &ldquo;I want only my rights, and that for which I paid,&rdquo; concluded Mr. Jenks.
+ &ldquo;Now, I gather that these men haven't treated you altogether fairly,
+ Bill.&rdquo;
+ </p>
+ <p>
+ &ldquo;Indeed they haven't. I helped 'em to the best of my ability, and all I
+ get out of it is to stay out on this lonely side of the mountain, and play
+ ghost. They owe me money, too, and they won't pay me, either, though they
+ have lots, for they sold some diamonds lately.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then they are still making diamonds?&rdquo; asked Mr. Jenks, eagerly. &ldquo;Have you
+ seen them? Do you know the secret?&rdquo;
+ </p>
+ <p>
+ &ldquo;No, I don't know it, for they won't let me in on it. I'm always sent out
+ of the cave just before they make the gems. But I know they've made some
+ lately, and have sold 'em. I want my share.&rdquo;
+ </p>
+ <p>
+ &ldquo;Look here!&rdquo; exclaimed Mr. Jenks, quickly, wishing to strike while the
+ iron was hot. &ldquo;I'll make you a proposition. Show us how to get into that
+ cave, unknown to the diamond makers, and I'll pay you twice what they
+ agreed to. Is it a bargain?&rdquo;
+ </p>
+ <p>
+ Bill Renshaw considered a moment. Then he thrust out his hand, clasped
+ that of Mr. Jenks, and exclaimed:
+ </p>
+ <p>
+ &ldquo;It is. I'll take you into the cave by an entrance that's seldom used.
+ There are four ways to get in. The one where the two men drove you back is
+ the rear one. The front one is on the other side of the mountain, but it's
+ so well concealed that you'd never find it. But I can take you to one
+ where you can get in, and those fellows will never know it. And, what's
+ more, I'll help you if it comes to a fight!&rdquo;
+ </p>
+ <p>
+ &ldquo;Good!&rdquo; exclaimed Mr. Jenks. &ldquo;I think we'll discover the secret of the
+ diamond makers this time,&rdquo; and he went to tell the others of the success
+ of his talk. Bill Renshaw had been converted from an enemy into a friend,
+ and the former phantom was now ready to lead Tom and the others into the
+ secret cave.
+ </p>
+ <p>
+ &ldquo;We'll start in the morning,&rdquo; decided Mr. Jenks, who, after many
+ disappointments, at last saw success ahead of him.

+ <h2>
+ CHAPTER XIX&mdash;IN THE SECRET CAVE
+ </h2>
+ <p>
+ Tom Swift was up at break of day, and the others were not far behind him.
+ </p>
+ <p>
+ &ldquo;Now for the secret cave!&rdquo; cried the young inventor as he gazed up the
+ mountain, in the interior of which the mysterious band of men were making
+ the diamonds.
+ </p>
+ <p>
+ &ldquo;Have you made any plans, Bill?&rdquo; asked Mr. Jenks of the former phantom,
+ who had cast his lot in with the adventurers. &ldquo;What will be the best
+ course for us to follow?&rdquo;
+ </p>
+ <p>
+ &ldquo;You just leave it to me, Mr. Jenks,&rdquo; was the answer. &ldquo;I'll get you into
+ the cave, and those fellows, who, I believe, are trying to do me out of my
+ rights, as they did you out of yours, will never know a thing about it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my finger-nails!&rdquo; cried Mr. Damon. &ldquo;That will be great! We can get
+ in the cave, and watch them make the diamonds at our leisure.&rdquo;
+ </p>
+ <p>
+ &ldquo;They don't make them every day,&rdquo; explained Renshaw. &ldquo;It seems they have
+ to wait for certain occasions. Mostly they make the diamonds when there's
+ a big storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;A big storm,&rdquo; asked the scientist with a sudden show of interest. &ldquo;Do you
+ mean one of those electrical storms, such as we had the other night?&rdquo;
+ </p>
+ <p>
+ &ldquo;That's it, Mr. Parker, though why they wait until there's a storm is more
+ than I can tell.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps they know that on such occasions no one will venture up the
+ mountain,&rdquo; spoke Mr. Damon.
+ </p>
+ <p>
+ &ldquo;No, it isn't that,&rdquo; declared the scientist. &ldquo;I think I am on the track of
+ a great scientific discovery, and I will soon be able to make observations
+ that will confirm it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I'm going to make an observation right now,&rdquo; said Tom, with a
+ laugh. &ldquo;I'm going to see what there is for breakfast.&rdquo;
+ </p>
+ <p>
+ &ldquo;And that reminds me,&rdquo; came from Mr. Jenks, &ldquo;shall we move our camp, Bill,
+ and take the tent with us to the cave?&rdquo;
+ </p>
+ <p>
+ &ldquo;I hardly think so,&rdquo; was the answer. &ldquo;I think the best plan would be to
+ conceal the tent somewhere around here, in case you might need it again.
+ You can also store what food you have left.&rdquo;
+ </p>
+ <p>
+ &ldquo;But, bless my appetite, we don't want to starve in that diamond cave!&rdquo;
+ objected Mr. Damon.
+ </p>
+ <p>
+ &ldquo;I'll see that you don't,&rdquo; declared Bill Renshaw. &ldquo;I'll take you in there,
+ unbeknownst to those fellows, and I'll provide you with plenty of food and
+ water. You see the cave is so big that there are some parts they never
+ visit.&rdquo;
+ </p>
+ <p>
+ &ldquo;And we can stay in one of those parts, and eat?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Sure,&rdquo; answered Bill.
+ </p>
+ <p>
+ &ldquo;And watch the diamond makers at work?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;That's it,&rdquo; replied the former phantom.
+ </p>
+ <p>
+ &ldquo;Then the sooner we get started the better,&rdquo; remarked Mr. Damon. Mr.
+ Parker said nothing. He appeared to be thinking deeply, and was tapping at
+ some rocks with his little hammer.
+ </p>
+ <p>
+ The advice of Bill Renshaw was followed, and the tent, and what food
+ remained, was concealed in the bushes, with rocks piled over to keep away
+ prowling animals. Then they started for the secret cave.
+ </p>
+ <p>
+ The man who played the part of a ghost picked up the framework and white
+ cloth that had formed his disguise.
+ </p>
+ <p>
+ &ldquo;I'll still have to use this,&rdquo; he explained, &ldquo;for I don't want those
+ fellows to know that I'm helping you. I'll continue to play the spirit of
+ the mountain, but there won't be much need of it. I don't think any more
+ people will come prospecting out here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Have you heard of the arrival of Farley Munson?&rdquo; asked Tom, as he related
+ the facts about the stowaway.
+ </p>
+ <p>
+ &ldquo;He hadn't arrived up to a day or so ago,&rdquo; answered Bill. &ldquo;I guess he's
+ still traveling. Farley is one of the heads of the gang,&rdquo; he added, &ldquo;and a
+ dangerous man.&rdquo;
+ </p>
+ <p>
+ As Bill led the way toward the cave, taking a route that the adventurers
+ had never suspected led to it, he explained that the cavern was a large
+ one, capable of holding an army.
+ </p>
+ <p>
+ &ldquo;But there's only a small part of it used by the diamond makers,&rdquo; he
+ added. &ldquo;They work in a small recess, near the summit of the mountain. The
+ little cave, where I'm going to take you, opens off from it by a long
+ passage. And, except that you'll be pretty much in the dark, you'll be
+ quite comfortable. There are tables, chairs, and some bunks in the place.
+ I can get you some lights, and plenty of food.&rdquo;
+ </p>
+ <p>
+ &ldquo;But, if you are seen taking away food, won't the others suspect
+ something?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I do pretty much as I please,&rdquo; said Bill. &ldquo;I go and come when I like. All
+ I'm supposed to do is to watch my two sides of the mountain, play the
+ ghost, and give warning when any one is coming. Sometimes I leave black
+ and white messages, like the one I put on your tent. Those fellows fix 'em
+ up for me. I've told 'em about you, though I didn't know who you were, and
+ they think you have gone, for the two men on guard at the rear entrance so
+ reported. Sometimes I stay out on the mountain for a couple of days at a
+ time, when the weather's good, and don't go back to the cave. Those times
+ I take food with me, and so if they see me making off with some supplies
+ they'll think I'm going to camp out.&rdquo;
+ </p>
+ <p>
+ &ldquo;It doesn't look as though we'd ever get into a cave near the top of the
+ mountain, going this way,&rdquo; said Tom, as they marched along. &ldquo;We're going
+ down, instead of up.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's the secret of this trail,&rdquo; explained Bill. &ldquo;We go down in a sort
+ of valley, and then go up a pretty stiff place, and then we're on a direct
+ trail to the entrance I told you about. It's a steep road to climb, but I
+ guess we can manage it.&rdquo;
+ </p>
+ <p>
+ And a hard climb the adventurers did find it. The road was almost as bad
+ as the one along the edge of the chasm, but they managed to negotiate it,
+ and finally found themselves on a fairly good trail.
+ </p>
+ <p>
+ &ldquo;We'll soon be there,&rdquo; Bill assured them. &ldquo;After you get in the little
+ cave, where I'm going to hide you, I'll have to leave you for a spell,
+ until I get my ghost rigging fixed up again. But I'll see that you have
+ plenty of food and drink.&rdquo;
+ </p>
+ <p>
+ A little later their guide came to a sudden halt, and peered around
+ anxiously.
+ </p>
+ <p>
+ &ldquo;What's the matter?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I was just looking to see if any of the men were about,&rdquo; he answered.
+ &ldquo;But I guess not&mdash;it looks all right. The entrance is right here.&rdquo;
+ </p>
+ <p>
+ They were on a side of the mountain, near the summit. Below stretched a
+ magnificent scene. A great valley lay at their feet, and they could look
+ off to many distant peaks. The main trail to Leadville, and the one to the
+ settlement of Indian Ridge, was in sight.
+ </p>
+ <p>
+ Suddenly Tom, who had been using a small but powerful telescope, uttered
+ an exclamation, and focussed the instrument on a speck that seemed moving
+ along on the trail below.
+ </p>
+ <p>
+ &ldquo;A man&mdash;coming up the mountain,&rdquo; cried Tom. &ldquo;And&mdash;it can't be&mdash;yet
+ it is&mdash;it's Farley Munson&mdash;the stowaway!&rdquo; he cried. &ldquo;He's coming
+ here!&rdquo;
+ </p>
+ <p>
+ &ldquo;Let me look!&rdquo; begged Mr. Jenks, taking the glass from Tom. An instant
+ later the diamond man exclaimed: &ldquo;Yes, it's Munson!&rdquo;
+ </p>
+ <p>
+ &ldquo;Then in here with you&mdash;quick!&rdquo; cried Renshaw. &ldquo;He can't see us yet,
+ and we'll be out of sight in another minute.&rdquo;
+ </p>
+ <p>
+ The former spirit pulled aside some thick bushes, and pointed to a hole
+ which was disclosed.
+ </p>
+ <p>
+ &ldquo;The entrance to the secret cave,&rdquo; he announced. &ldquo;Slip in all of you.&rdquo;
+ </p>
+ <p>
+ Tom, after another glance at the man toiling his way up the mountain,
+ entered the cavern. He was followed by the others. Bill was the last to
+ enter, and he replaced the bushes over the entrance.
+ </p>
+ <p>
+ &ldquo;At last!&rdquo; exclaimed Mr. Jenks, as he gazed up at the roof of the
+ dimly-lighted vault in which they found themselves.
+ </p>
+ <p>
+ &ldquo;Yes, we're in the diamond makers' secret cave,&rdquo; added Tom. &ldquo;Now to catch
+ them at work!&rdquo;
+ </p>
+ <p>
+ &ldquo;Come on,&rdquo; advised Bill, in a low tone, &ldquo;We're not safe yet,&rdquo; and he
+ produced a lantern from some hidden recess, lighted the wick, and led the
+ way. As the others followed they were aware of a subdued noise in the
+ great cavern.

+ <h2>
+ CHAPTER XX&mdash;MAKING THE DIAMONDS
+ </h2>
+ <p>
+ &ldquo;What's that noise?&rdquo; asked Tom, as their guide flashed the lantern to show
+ them the way.
+ </p>
+ <p>
+ &ldquo;That's the men getting ready to make diamonds, I guess,&rdquo; was the answer.
+ &ldquo;You see it takes quite a while to get the stuff ready. I don't know what
+ they use&mdash;they never tell me any of their secrets.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I know the ingredients well enough,&rdquo; said Mr. Jenks, &ldquo;but I don't
+ know the secret of how they apply the terrific heat and pressure necessary
+ to fuse the materials into diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, you'll soon know,&rdquo; declared Bill Renshaw. &ldquo;Of course it isn't
+ always successful. I've known 'em to try half a dozen times before they
+ got any diamonds big enough to satisfy 'em. They gave me some of the small
+ ones when I asked for my wages.
+ </p>
+ <p>
+ &ldquo;How did you come to get in with these men?&rdquo; asked Tom, curious to
+ understand how a person seemingly as honest as Renshaw appeared to be had
+ cast his lot in with the men who had broken faith with Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Oh, I've lived around these parts all my life,&rdquo; was the answer. &ldquo;I knew
+ of this cave before these diamond fellers came to it. In fact, I showed it
+ to 'em. It was several years ago that a party of men who were prospecting
+ around here came to me and asked if I knew of a small cave near the top of
+ a high mountain, where lightning storms were frequent. I told them about
+ Phantom Mountain, as it was called then, and also of this cave. If there's
+ any place where they have worse lightning storms than here, I'd like to
+ know it. They scare me, sometimes, like the night when that landslide
+ happened, and I'm sort of used to 'em.
+ </p>
+ <p>
+ &ldquo;Well, I took these men to the cave, and they hired me as a sort of
+ lookout. Then they began their work, and at first I didn't know what they
+ were up to, but finally I caught on. Then Mr. Jenks came, and disappeared
+ mysteriously, though then I didn't know that they had played a trick on
+ him. I was outside most of the time, pretending I was the ghost. So that's
+ how I came to get in with 'em, and I wish I was out.&rdquo;
+ </p>
+ <p>
+ &ldquo;You soon will be, I think,&rdquo; declared Mr. Jenks. &ldquo;But won't our talking be
+ heard by the men?&rdquo;
+ </p>
+ <p>
+ &ldquo;No danger. There is a thick wall between this part of the cave, and the
+ part where they live and work. I'll soon have you well hid, and then you
+ wait until I come back.&rdquo;
+ </p>
+ <p>
+ &ldquo;What about Munson?&rdquo; asked Tom. &ldquo;He is evidently on his way here to tell
+ his confederates about us.&rdquo;
+ </p>
+ <p>
+ &ldquo;He won't know what has happened to us,&rdquo; said Mr. Jenks, &ldquo;and he won't see
+ anything of us. I guess we're safe enough.&rdquo;
+ </p>
+ <p>
+ Through the dark passage they followed Bill Renshaw until he came to a
+ halt in a place that suddenly widened and broadened into a good-sized
+ cave.
+ </p>
+ <p>
+ &ldquo;Here's your stopping place,&rdquo; said the former ghost. &ldquo;Now if you follow
+ that passage, off to the left,&rdquo; and he pointed to it, &ldquo;you'll come to the
+ larger part of the cave where the diamond makers are. But go cautiously,
+ and don't make any noise. I won't be responsible for what happens.&rdquo;
+ </p>
+ <p>
+ &ldquo;We'll take all the risk,&rdquo; interrupted Tom.
+ </p>
+ <p>
+ &ldquo;All right. Now there's a couple of lanterns around here. I'll light them,
+ and leave you for a while until I can get some grub. I'll be back as soon
+ as I can.&rdquo;
+ </p>
+ <p>
+ He glided away, after lighting two lanterns, by the gleams of which the
+ adventurers could see that they were in a vaulted cavern that had
+ evidently been fitted up as a living apartment. The sides, roof and floor
+ were of stone. It was clean, and the air was fresh. There were some
+ chairs, a table, and several cots, with pieces of bagging for bedding,
+ though it was warm in the place.
+ </p>
+ <p>
+ &ldquo;I guess we can stay here until we discover the secret,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;Bless my watch! We can if we have something to eat,&rdquo; came from Mr. Damon,
+ with something like a sigh. &ldquo;I'm hungry!&rdquo;
+ </p>
+ <p>
+ &ldquo;And I want to make some observations,&rdquo; said Mr. Parker. &ldquo;From what I have
+ seen of this mountain, I would not be surprised if this cave was to be
+ suddenly destroyed by a landslide or a lightning bolt. I will make some
+ further investigations.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, if it's going to cause you to make such gloomy prophecies as that,
+ I'd just as soon you wouldn't look any further,&rdquo; spoke Tom, in a low
+ voice. But Mr. Parker, taking one of the lanterns, set about examining the
+ rock of which the cave consisted.
+ </p>
+ <p>
+ In a short time Bill Renshaw returned with enough food to last for two
+ days. He said he was going out on the mountain once more to act the part
+ of a lookout, and would visit the adventurers again the next day.
+ </p>
+ <p>
+ &ldquo;In the meanwhile you can do just as you please,&rdquo; he said. &ldquo;Nobody is
+ likely to disturb you here, and you can sneak up and take a look at the
+ men in the other cave whenever you're ready. Only be careful&mdash;that's
+ all I've got to say. They're desperate men.&rdquo;
+ </p>
+ <p>
+ It was not very pleasant, eating in the gloomy cavern, but they made the
+ best of it. They cooked on a small oil-stove they found in the place, and
+ after some hot coffee they felt much better.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked Tom, after a while, &ldquo;shall we take a chance, and go look
+ at the men at work?&rdquo;
+ </p>
+ <p>
+ &ldquo;I think so,&rdquo; answered Mr. Jenks. &ldquo;The sooner we discover this mystery,
+ the better. Then we can go back home.&rdquo;
+ </p>
+ <p>
+ &ldquo;And recover my airship,&rdquo; added Tom, who was a bit uneasy regarding the
+ safety of the Red Cloud.
+ </p>
+ <p>
+ &ldquo;Then, bless my finger-rings! let's go and see if we can find the big cave
+ your friend the ghost told us of,&rdquo; suggested Mr. Damon.
+ </p>
+ <p>
+ Cautiously they made their way along the passage Bill had pointed out. As
+ they went forward the subdued noise became louder, and finally they could
+ feel the vibration of machinery.
+ </p>
+ <p>
+ &ldquo;This is the place,&rdquo; whispered Mr. Jenks. &ldquo;That sound we hear is one of
+ the mixing machines, for grinding the materials&mdash;carbon and the other
+ substances&mdash;which go to make up the diamonds. I remember hearing that
+ when I was in the cave before.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we must be near the place,&rdquo; observed Tom.
+ </p>
+ <p>
+ &ldquo;Yes, but I didn't have much chance to look around when I was here before.
+ They wouldn't let me. I never even knew of the small cave Bill took us
+ to.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, if we're close to it, we'd better go cautiously, and not talk any
+ more than we're obliged to,&rdquo; suggested Mr. Parker, and they agreed that
+ this was good advice.
+ </p>
+ <p>
+ They walked on softly. Suddenly Tom, who was in the lead, saw a gleam of
+ light.
+ </p>
+ <p>
+ &ldquo;We're here,&rdquo; he whispered. &ldquo;I'll put out our lantern, now,&rdquo; which he did.
+ Then, stealing forward he and the others beheld a curious sight. The
+ tunnel they were in ended at a small hole which opened into a large
+ cavern, and, fortunately, this opening was concealed from the view of
+ those in the main place.
+ </p>
+ <p>
+ &ldquo;The diamond makers!&rdquo; whispered Tom, hoarsely, pointing to several men
+ grouped about a number of strange machines.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;the very place where I was,&rdquo; answered Mr. Jenks, &ldquo;and there is
+ the apparatus&mdash;the steel box&mdash;from which the diamonds are taken&mdash;now
+ to see how they make them.&rdquo;
+ </p>
+ <p>
+ Fascinated, the adventurers looked into the cave. The men there were
+ unaware of the presence of our friends, and were busily engaged. Some
+ attended to the grinding machine, the roar and clatter of which made it
+ possible for Tom and the others to talk and move about without being
+ overheard. Into this machine certain ingredients were put, and they were
+ then pulverized, and taken out in powdery form.
+ </p>
+ <p>
+ The power to run the mixing machine was a gasoline motor, which
+ chug-chugged away in one corner of the cave.
+ </p>
+ <p>
+ As the powder was taken out, other men fashioned it into small balls,
+ which were put on pan, and into a sort of oven, that was heated by a
+ gasoline stove.
+ </p>
+ <p>
+ &ldquo;Is that how they make the diamonds?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;That is evidently the first step,&rdquo; said Mr. Jenks. &ldquo;Those balls of
+ powdered chemicals are partly baked, and then they are put into the steel
+ box. In some way terrific heat and pressure are applied, and the diamonds
+ are made. But how the heat and pressure are obtained is what we have yet
+ to learn.&rdquo;
+ </p>
+ <p>
+ He paused to watch the men at work. They were all busy, some attending to
+ the machines, and others coming and going in and out of the cave. In one
+ part a man was apparently getting ready a meal.
+ </p>
+ <p>
+ Suddenly there rushed into the cave a man who seemed much excited.
+ </p>
+ <p>
+ &ldquo;Are you nearly ready with that stuff?&rdquo; he cried. &ldquo;There's a good storm
+ gathering on the mountain!&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, we'll be ready in half an hour,&rdquo; answered one of the men at the
+ mixing machine.
+ </p>
+ <p>
+ &ldquo;Good. It will be flashing lightning bolts then, and we can see what luck
+ we have. The last batch was a failure.&rdquo; The man hurried out again. Mr.
+ Parker touched Tom and Mr. Jenks on their shoulders.
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I know the secret of making the diamonds,&rdquo; said the scientist.
+ </p>
+ <p>
+ &ldquo;What?&rdquo; cried Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;It is by the awful power of the lightning bolts!&rdquo; whispered Mr. Parker.
+ &ldquo;Everything is explained now&mdash;the reason why they make diamonds in
+ this lonely place, near the top of the mountain. They need a place where
+ the lightning is powerful. I can understand it now&mdash;I suspected it
+ before. They make diamonds by lightning!&rdquo;
+ </p>
+ <p>
+ &ldquo;Are you sure?&rdquo; cried Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Positive.&rdquo;
+ </p>
+ <p>
+ &ldquo;I agree with you,&rdquo; said Tom Swift. &ldquo;I was just getting on that track
+ myself, when I saw the electric wires running to the steel box. That
+ explains the upright rod on the top of the mountain. The man says a storm
+ is coming&mdash;very well; we'll stay here and watch them make diamonds!&rdquo;
+ </p>
+ <p>
+ As he spoke there came the mutter of thunder, and the mountain vibrated
+ slightly. The men in the cave redoubled their activity. Tom and his
+ friends felt that the secret process they had so long sought was about to
+ be demonstrated before their eyes.

+ <h2>
+ CHAPTER XXI&mdash;FLASHING GEMS
+ </h2>
+ <p>
+ Eagerly the adventurers looked through the opening at the end of the
+ passage into the larger cave. The men opened the small oven in which the
+ balls of white chemicals and carbon mixed, had been baked, and a pile of
+ things, that looked like irregularly-shaped marbles, were placed in the
+ steel box.
+ </p>
+ <p>
+ This box, which was about the size of a trunk, was of massive metal. It
+ was placed in a recess in the solid rock, and all about were layers of
+ asbestos and other substances that were nonconductors of heat.
+ </p>
+ <p>
+ &ldquo;That box becomes red hot,&rdquo; exclaimed Mr. Jenks, in a whisper. &ldquo;When
+ things are in readiness, that lever is pulled and the diamonds are made. I
+ pulled it once, but I did not then know the process involved. I supposed
+ that the lightning had nothing to do with making the diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;It has&mdash;a most important part,&rdquo; said Mr. Parker. The hidden
+ adventurers could talk in perfect safety now, for the men in the large
+ cave were too excited to pay much attention to them. The muttering of the
+ thunder grew louder, and at times a particularly loud crash told that a
+ bolt had struck somewhere in the vicinity of the cave.
+ </p>
+ <p>
+ &ldquo;But, bless my watch-charm!&rdquo; exclaimed Mr. Damon, &ldquo;I didn't know lightning
+ made diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;It does not&mdash;always,&rdquo; went on the scientist. &ldquo;But great heat and
+ pressure are necessary to create the gems. In nature this was probably
+ obtained by prehistoric volcanic fires, and by the terrific pressure of
+ immense rocks. It is possible to make diamonds in the laboratory of the
+ chemist, but they are so minute as to be practically valueless.
+ </p>
+ <p>
+ &ldquo;However, these men seem to have hit upon a new plan. They utilize the
+ terrific heat of lightning, and the pressure which is instantaneously
+ obtained when the bolt strikes. I am anxious to see how it is done. Look,
+ I think they are getting ready to make the gems.&rdquo;
+ </p>
+ <p>
+ Indeed there seemed to be an air of expectancy among the diamond makers.
+ The mixing machine had now been stopped, and, as it was more quiet in the
+ cave, our friends, in their hiding-place, had to speak in mere whispers.
+ All the men were now gathered about the great steel box.
+ </p>
+ <p>
+ This receptacle had been closed by a solid metal door, which was screwed
+ and clamped tight. Then one of the men examined a number of heavily
+ insulated electric wires that extended from the box off into the darkness
+ where Tom and his companions could not discern them.
+ </p>
+ <p>
+ &ldquo;That's Folwell&mdash;the man I befriended, and who got me into this
+ game,&rdquo; whispered Mr. Jenks. &ldquo;He was also one of the first to turn against
+ me. I think he's one of the leaders.&rdquo;
+ </p>
+ <p>
+ Folwell came back, after having gone into a dark part of the cave. He went
+ over to an electrical switch on one of the stone walls.
+ </p>
+ <p>
+ &ldquo;It's almost time,&rdquo; Tom heard him say to his confederates. &ldquo;The storm is
+ coming up rapidly.&rdquo;
+ </p>
+ <p>
+ &ldquo;Will it be severe enough?&rdquo; asked one of the helpers. &ldquo;We had all our work
+ for nothing last time. The flashes weren't heavy enough.&rdquo;
+ </p>
+ <p>
+ &ldquo;These will be,&rdquo; asserted Folwell. &ldquo;The indicator shows nearly a million
+ volts now, and it's increasing.&rdquo;
+ </p>
+ <p>
+ &ldquo;A million volts!&rdquo; exclaimed Tom. &ldquo;I hope it doesn't strike anywhere
+ around here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, it will probably be harmlessly conducted down on the heavy wires,&rdquo;
+ said Mr. Parker. &ldquo;We are in no danger, at present, though ultimately I
+ expect to see the whole mountain shattered by a lightning bolt.&rdquo;
+ </p>
+ <p>
+ &ldquo;Cheerful prospect,&rdquo; murmured Tom.
+ </p>
+ <p>
+ There was a terrific crash outside. The rocky floor of the cave trembled.
+ </p>
+ <p>
+ &ldquo;Here she comes!&rdquo; cried Folwell. &ldquo;Get back, everybody! I'm going to throw
+ over the switch now!&rdquo;
+ </p>
+ <p>
+ The men retreated well away from the steel box. Folwell threw over the
+ lever&mdash;the same one Mr. Jenks remembered pulling. Then the man ran to
+ the electric switch on the wall, and snapped that into place, establishing
+ a connection.
+ </p>
+ <p>
+ There was a moment's pause, as Folwell ran to join the others in their
+ place of safety. Then from without there came a most nerve-racking and
+ terrifying crash. It seemed as if the very mountain would be rent into
+ fragments.
+ </p>
+ <p>
+ Watching with eager eyes, the adventurers saw sparks flash from the steel
+ box. Instantly it became red hot, and then glowed white and incandescent.
+ It was almost at the melting point.
+ </p>
+ <p>
+ Then came comparative quiet, as the echoes of the thunder died away amid
+ the mountain peaks.
+ </p>
+ <p>
+ &ldquo;I guess that did the trick!&rdquo; cried Folwell. &ldquo;It was a terrific crash all
+ right!&rdquo;
+ </p>
+ <p>
+ He and the others ran forward. The steel box was now a cherry red, for it
+ was cooling. Folwell threw back the lever, and another man disconnected
+ the switch. There was a period of waiting until the box was cool enough to
+ open. Then the heavy door was swung back.
+ </p>
+ <p>
+ With a long iron rod Folwell drew something from the retort. It was the
+ tray which had held the white balls. But they were white no longer, for
+ they had been turned into diamonds. From their hiding-place Tom and the
+ others could see the flashing gems, for, in spite of the fact that the
+ diamonds were uncut, some of them sparkled most brilliantly, due to the
+ peculiar manner in which they were made.
+ </p>
+ <p>
+ &ldquo;We have the secret of the diamonds!&rdquo; whispered Mr. Jenks. &ldquo;There must be
+ a quart of the gems there!&rdquo;
+ </p>
+ <p>
+ The men gathered about Folwell, uttering exclamations of delight. The
+ diamonds were too hot to handle yet.
+ </p>
+ <p>
+ &ldquo;That's going some!&rdquo; exclaimed the chief of the diamond makers. &ldquo;We have a
+ small fortune here.&rdquo;
+ </p>
+ <p>
+ The was a sudden commotion at one end of the cave. A man rushed in. At the
+ sight of him Tom stared and uttered an exclamation.
+ </p>
+ <p>
+ &ldquo;Munson&mdash;the stowaway!&rdquo; he whispered.
+ </p>
+ <p>
+ &ldquo;Hello!&rdquo; cried Folwell, as he saw his confederate. &ldquo;I thought you were
+ East, keeping Jenks away from here.&rdquo;
+ </p>
+ <p>
+ &ldquo;He got the best of me!&rdquo; cried Munson, &ldquo;he and that Tom Swift! I stowed
+ away on their airship, but they found me out by a wireless message, and
+ marooned me in the woods. I've been trying to get here ever since! Didn't
+ you get my messages of warning?&rdquo;
+ </p>
+ <p>
+ &ldquo;No&mdash;what warnings?&rdquo; cried Folwell.
+ </p>
+ <p>
+ &ldquo;About Jenks, Tom Swift and the others. They're here&mdash;they must be on
+ Phantom Mountain now. In fact, I shouldn't be surprised if they were in
+ this cave. I traced them to their camp, but they're gone. They may be
+ among us now&mdash;in some of the secret recesses!&rdquo;
+ </p>
+ <p>
+ For an instant Folwell stared at the bearer of these tidings. Then he
+ cried out:
+ </p>
+ <p>
+ &ldquo;Scatter men, and find these fellows! We must get them before they
+ discover our secret!&rdquo;
+ </p>
+ <p>
+ &ldquo;It's too late&mdash;we know it!&rdquo; exulted Tom Swift. Then he whispered to
+ the others to hurry to the part of the cave where Bill Renshaw had first
+ hidden them.

+ <h2>
+ CHAPTER XXII&mdash;PRISONERS
+ </h2>
+ <p>
+ &ldquo;Do you think there is any danger of them finding us?&rdquo; asked Mr. Damon, as
+ he hurried along beside Tom.
+ </p>
+ <p>
+ &ldquo;I'm afraid so,&rdquo; was the answer. &ldquo;I've been worried ever since we saw
+ Munson heading this way. But we couldn't do any differently.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps Bill Renshaw may be able to conceal us,&rdquo; suggested Mr. Jenks.
+ &ldquo;Very likely he knows that Munson is on hand. Perhaps we will be safe for
+ a while. I want to make a few more observations as to how they manufacture
+ the diamonds, and then, with what I already know, I'll have the secret.&rdquo;
+ </p>
+ <p>
+ &ldquo;And I'd like to make some scientific tests of the sides and bottom rocks
+ of the cave,&rdquo; spoke Mr. Parker. &ldquo;I think it will bear out my theory that
+ the mountain will soon be destroyed.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, you were right about Earthquake Island, and you may be right about
+ this mountain,&rdquo; said Tom, &ldquo;but if it is going to be annihilated I hope we
+ get far enough away from it.&rdquo;
+ </p>
+ <p>
+ &ldquo;We can keep our presence here a secret for a few more days, I think that
+ will be long enough,&rdquo; proceeded Mr. Jenks. &ldquo;Then we will leave.&rdquo;
+ </p>
+ <p>
+ &ldquo;And, in the meanwhile, they'll be searching for us,&rdquo; objected Mr. Damon.
+ &ldquo;I wish that ghost-chap would come back and tell us what to do. Bless my
+ liver-pin, but we are going to be in considerable danger, I'm afraid!
+ Those men may capture us, and decide to make diamond dust from us.&rdquo;
+ </p>
+ <p>
+ &ldquo;Come on&mdash;hurry to the little cave,&rdquo; urged Tom. &ldquo;Then we'll get ready
+ to defend ourselves.&rdquo;
+ </p>
+ <p>
+ &ldquo;The main cave is a large one,&rdquo; said Mr. Jenks, &ldquo;and there are many hiding
+ places in it. In fact, it is so large that it will take those fellows
+ several days to complete a circuit of it. By that time Bill Renshaw may
+ come back, and take us to some place in which they have already searched
+ for us. Then we'll be comparatively safe.&rdquo;
+ </p>
+ <p>
+ This thought was some consolation to them, as they made their way through
+ the dark passage, dimly illuminated by the lantern they had rekindled, to
+ the place where Bill had hidden them. They found things as they had left
+ them, and proceeded to get a meal, though Tom said it would be best not to
+ cook anything, or even to make coffee, for fear the odors would enable the
+ searchers to trail them.
+ </p>
+ <p>
+ So they ate cold food, glad to get that. Silently they sat about the
+ dimly-lighted cavern, and discussed the situation. True they might even
+ now retreat, going out of the entrance Bill had showed them, and so
+ escape. But Mr. Jenks felt that his mission was not completed yet, and
+ they all agreed to stay with him.
+ </p>
+ <p>
+ &ldquo;For there are several points about making diamonds that are not quite
+ clear to me,&rdquo; he said. &ldquo;I need to know how that steel box is constructed,
+ how the electrical switches are arranged, what kind of lightning rods they
+ use, and how they regulate the pressure. The other things, and how to mix
+ the ingredients, I already know.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'll do our best to help you,&rdquo; promised Tom. &ldquo;But now I think we
+ had better see what sort of a defense we can put up. We have our guns and
+ revolvers, and with these chairs and tables we can build a sort of
+ barricade behind which we can take refuge if those fellows do discover our
+ hiding place.&rdquo;
+ </p>
+ <p>
+ This was conceded to be a good idea, and soon a rude sort of fort was
+ made, behind which the adventurers could take their stand and fight, if
+ necessary, though they hoped this would not come to pass.
+ </p>
+ <p>
+ They remained quietly in the cave the remainder of that day, and, when it
+ was night, as they could tell by their timepieces&mdash;there was no
+ daylight&mdash;they divided the hours into watches, taking turns standing
+ guard.
+ </p>
+ <p>
+ Morning, at least in point of time, came without any disturbance, and they
+ made a cold breakfast. They hoped that Bill Renshaw would come, but he did
+ not appear.
+ </p>
+ <p>
+ After sitting in the dark cave until afternoon, Tom said:
+ </p>
+ <p>
+ &ldquo;I think we might as well go and take another observation of the big cave.
+ We can tell what the men are doing, then, for they don't seem to have been
+ near us. Maybe they have given up the search for us, and we can see them
+ at work, and Mr. Jenks can gain what further knowledge he needs.&rdquo;
+ </p>
+ <p>
+ &ldquo;That will be a good plan,&rdquo; agreed the diamond man. &ldquo;It's maddening to sit
+ here, doing nothing.&rdquo;
+ </p>
+ <p>
+ &ldquo;And it will be comparatively safe to go from here to our former post of
+ observation,&rdquo; added Tom, &ldquo;for there doesn't seem to be any opening along
+ the tunnel, into the larger cave, except the place where we were.&rdquo;
+ </p>
+ <p>
+ Accordingly they started off. Cautiously they looked through the opening
+ into the apartment where they had seen the diamonds made.
+ </p>
+ <p>
+ &ldquo;There's not a soul here!&rdquo; exclaimed Tom, in a whisper. The others looked.
+ The place was deserted&mdash;the machinery silent. Mr. Jenks peered in for
+ a moment, and then exclaimed:
+ </p>
+ <p>
+ &ldquo;I'm going in! Now's my chance to find out all that I wish to know! It may
+ never come again, and then we can soon leave Phantom Mountain!&rdquo;
+ </p>
+ <p>
+ It was a daring plan, but it seemed to be the best one to follow. They
+ were all tired of inactivity. Mr. Jenks managed to get through the
+ opening, and dropped into the big cave. The others followed. Mr. Jenks
+ hurried over to the steel box, and began an examination of it. Tom Swift
+ was looking at the electrical switch. He saw how it was constructed. Mr.
+ Damon and Mr. Parker were peering interestedly about.
+ </p>
+ <p>
+ Suddenly the sound of voices was heard, and the echo of footsteps. Mr.
+ Jenks started.
+ </p>
+ <p>
+ &ldquo;They're coming back!&rdquo; he whispered hoarsely. &ldquo;Run!&rdquo;
+ </p>
+ <p>
+ They all turned and sped toward their hiding place. But they were too
+ late. An instant later Folwell, Munson and the other diamond makers
+ confronted them. Our friends made a bold rush, but were caught before they
+ could go ten feet.
+ </p>
+ <p>
+ &ldquo;We have them!&rdquo; cried Munson. &ldquo;They walked right into our hands!&rdquo;
+ </p>
+ <p>
+ It was true. Tom Swift and the others were the prisoners of the diamond
+ makers.

+ <h2>
+ CHAPTER XXIII&mdash;BROKEN BONDS
+ </h2>
+ <p>
+ &ldquo;Well,&rdquo; remarked Tom Swift, in mournful tones, &ldquo;this looks as if we were
+ up against it; doesn't it?&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my umbrella, it certainly does,&rdquo; agreed Mr. Damon.
+ </p>
+ <p>
+ &ldquo;And it's all my fault,&rdquo; said Mr. Jenks. &ldquo;I shouldn't have gone into the
+ big cave. I might have known those men would come back any time.&rdquo;
+ </p>
+ <p>
+ The above conversation took place as our friends lay securely bound in a
+ small cave, or recess, opening from the larger cavern, where, about an
+ hour before, they had been captured and made prisoners by the diamond
+ makers. Despite their struggles they had been overpowered and bound, being
+ carried to the cave, where they were laid in a row on some old bags.
+ </p>
+ <p>
+ &ldquo;It certainly is a most unpleasant situation, to say the least,&rdquo; observed
+ Mr. Parker.
+ </p>
+ <p>
+ &ldquo;And all my fault,&rdquo; repeated Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Oh, no it isn't,&rdquo; declared Tom Swift, quickly. &ldquo;We were just as ready to
+ follow you into that cave as you were to go. No one could tell that the
+ men would return so soon. It's nobody's fault. It's just our bad luck.&rdquo;
+ </p>
+ <p>
+ From where he lay, tied hand and foot, the young inventor could look out
+ into the cave where he and the others had been caught. The diamond makers
+ were busily engaged, apparently in getting ready to manufacture another
+ batch of the precious stones. They paid little attention to their
+ captives, save to warn them, when they had first been taken into the
+ little cave, that it was useless to try to escape.
+ </p>
+ <p>
+ &ldquo;They needn't have told us that,&rdquo; observed Tom, as he and the others were
+ talking over their situation in low voices. &ldquo;I don't believe any one could
+ loosen these ropes.&rdquo;
+ </p>
+ <p>
+ &ldquo;They certainly are pretty tight,&rdquo; agreed Mr. Damon. &ldquo;I've been tugging
+ and straining at mine for the last half hour, and all I've succeeded in
+ doing is to make the cords cut into my flesh.&rdquo;
+ </p>
+ <p>
+ &ldquo;Better give it up,&rdquo; advised Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;We'll just have to wait.&rdquo;
+ </p>
+ <p>
+ &ldquo;For what?&rdquo; the scientist wanted to know.
+ </p>
+ <p>
+ &ldquo;To see what they'll do with us. They can't keep us here forever. They'll
+ have to let us go some time.&rdquo; Following their capture, Folwell and Munson,
+ the latter the stowaway of the airship, had been in earnest conversation
+ regarding our friends, but what conclusion they had reached the
+ adventurers could only guess.
+ </p>
+ <p>
+ &ldquo;And we didn't have time to examine the diamond-making machinery close
+ enough so that we could duplicate it if necessary,&rdquo; complained Tom, a
+ little later.
+ </p>
+ <p>
+ &ldquo;No,&rdquo; agreed Mr. Jenks. &ldquo;There are certain things about it that are not
+ clear to me. Well, I don't believe I'll have another chance to inspect it.
+ They'll take good care of that, though they seem to be getting ready to
+ make more diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps they're going to manufacture a big batch, and then leave this
+ place,&rdquo; suggested Mr. Damon. &ldquo;They will probably go to some other secret
+ cave, and leave us here.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope they untie us before they leave, and give us something to eat,&rdquo;
+ remarked the young inventor.
+ </p>
+ <p>
+ For two hours longer the captives lay there, in most uncomfortable
+ positions. Then Folwell and Munson, leaving the group of diamond makers
+ who were grouped about the machinery, approached the captives.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked Munson, &ldquo;we got ahead of you after all; didn't we. You
+ thought you had our secret, but it will be a long while before you ever
+ make diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;What are you going to do with us?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Never mind. You came where you had no right to, and you must take the
+ consequences.&rdquo;
+ </p>
+ <p>
+ &ldquo;We did have a right to come here!&rdquo; exclaimed Mr. Jenks. &ldquo;I am entitled to
+ know how the diamonds are made. I paid for the information, and you
+ tricked me. If ever it's possible I'll have the whole gang arrested for
+ swindling.&rdquo;
+ </p>
+ <p>
+ &ldquo;You'll never get the chance!&rdquo; declared Folwell. &ldquo;You were given some
+ diamonds for the money you invested, and that makes us square.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, it doesn't!&rdquo; declared Mr. Jenks. &ldquo;I invested the money to learn how
+ to make diamonds, and you know it! You tricked me, and I had a right to
+ try to discover your secret! I nearly have it, too, and I'll get it
+ completely before I'm done with you!&rdquo;
+ </p>
+ <p>
+ &ldquo;No, you won't!&rdquo; boasted Folwell. &ldquo;But we didn't come here to tell you
+ that. We came to give you something to eat. We're not savages and we'll
+ treat you as well as we can in spite of the fact that you are trespassers.
+ We're going to give you some grub, but I warn you that any attempt to
+ escape will mean that some of you will get hurt.&rdquo;
+ </p>
+ <p>
+ He signalled to some of his confederates. These men unbound the captives'
+ arms, and stood over them while they ate some coarse food that was brought
+ into the small cave. They were given coffee to drink, and then, when the
+ simple meal was over, they were securely bound again, and left to
+ themselves, while the diamond makers went back to their machinery.
+ </p>
+ <p>
+ It was evident that they were going to attempt a big operation, for an
+ unusually large quantity of the white stuff was prepared. The prisoners
+ watched them idly. They could see some but not all of the operations. In
+ this way several hours passed.
+ </p>
+ <p>
+ Gloom possessed the hearts of Tom and his friends. Not only had their
+ expedition been almost a failure so far, but the young inventor was
+ worried lest the gang might discover and wreck his airship. This would
+ prove a serious loss. Lying there in the semi-darkness the lad imagined
+ all sorts of unpleasant happenings.
+ </p>
+ <p>
+ At times he dozed off, as did the others. They had become somewhat used to
+ the pain caused by the bonds, for their nerves were numb from the strain
+ and pressure.
+ </p>
+ <p>
+ Once, as he was lightly sleeping, Tom was awakened by hearing loud voices
+ in the main cave. He looked out, rolling over slightly to get a better
+ view. He saw the man who, once before had run in to give news of an
+ approaching electrical storm.
+ </p>
+ <p>
+ &ldquo;Are you fellows all ready?&rdquo; asked this same man again.
+ </p>
+ <p>
+ &ldquo;Yes. Is there another storm coming?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, and it's going to be a corker!&rdquo; was the reply. &ldquo;It's one of the
+ worst I've ever seen. It's sweeping right up the valley. It'll be here in
+ an hour.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's good. We need a big flash to make all the material we have
+ prepared into diamonds. It's the biggest batch we ever tried. I hope it
+ succeeds, for we're going to leave&mdash;&rdquo; The rest was in so low a tone
+ that Tom could not catch it.
+ </p>
+ <p>
+ The storm messenger departed. Folwell and Munson busied themselves about
+ the machinery. Tom dozed off again, dimly wondering what had become of
+ Bill Renshaw, and whether the former ghost knew of their plight. The
+ others were asleep, as the young inventor saw by the dim light of a
+ lantern in the cave. Then, he too, shut his eyes.
+ </p>
+ <p>
+ Tom was suddenly awakened by feeling some one's hands moving about his
+ clothing. At first he thought it was one of the diamond-making gang, who
+ had sneaked in to rob him. &ldquo;Here! What are you up to?&rdquo; exclaimed Tom.
+ </p>
+ <p>
+ &ldquo;Quiet!&rdquo; cautioned a voice. &ldquo;Are you all here?&rdquo;
+ </p>
+ <p>
+ &ldquo;All of us&mdash;yes. But who are you?&rdquo;
+ </p>
+ <p>
+ &ldquo;Easy&mdash;keep quiet, Tom Swift! I'm Bill Renshaw! I've been searching
+ all over for you, since I got back to your cave and found it empty. Now
+ I'm going to free you. I got in here by a secret entrance. Wait, I'll cut
+ your ropes.&rdquo; There was a slight sound, and an instant later Tom was freed
+ from his bonds.

+ <h2>
+ CHAPTER XXIV&mdash;IN GREAT PERIL
+ </h2>
+ <p>
+ The young inventor could scarcely believe the good luck that had so
+ unexpectedly come to him and his companions. No sooner was Tom able to
+ move freely about than Bill Renshaw performed the same service for Mr.
+ Jenks and the others, cautioning them to be quiet as he awakened them, and
+ cut the ropes.
+ </p>
+ <p>
+ &ldquo;Bless my circulation!&rdquo; exclaimed Mr. Damon, in a hoarse whisper. &ldquo;How did
+ you ever get here. I'd given ourselves up for lost.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I came in off the mountain, as there's a big storm due,&rdquo; explained
+ the man. &ldquo;There was no need of me playing the haunt in daytime, anyhow. I
+ went to the cave, found you and your things gone, and I surmised that you
+ might have walked into some trap.&rdquo;
+ </p>
+ <p>
+ &ldquo;We did,&rdquo; admitted Mr. Jenks, grimly.
+ </p>
+ <p>
+ &ldquo;Well, I hunted around until I found you,&rdquo; went on Bill. &ldquo;This mountain is
+ honeycombed with caves, all opening from the large one, I know them better
+ than these fellows do, so I could explore freely, and keep out of their
+ sight. They didn't know that there was a second entrance to this place,
+ but I did, and I made for it, when I couldn't find you in some of the
+ other caves where I looked. And, sure enough, here you were.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, we can't thank you enough,&rdquo; said Mr. Parker. &ldquo;But you say there is
+ a big storm coming?&rdquo;
+ </p>
+ <p>
+ &ldquo;One of the biggest that's been around these parts in some time,&rdquo; replied
+ Bill.
+ </p>
+ <p>
+ &ldquo;Then perhaps the mountain will be destroyed,&rdquo; went on the scientist, as
+ calmly as if he had remarked that it might rain.
+ </p>
+ <p>
+ &ldquo;I hope nothing like that happens until we get away,&rdquo; spoke Mr. Damon,
+ fervently.
+ </p>
+ <p>
+ &ldquo;What had we better do?&rdquo; inquired Tom.
+ </p>
+ <p>
+ &ldquo;Get away, unless you want to discover some more of their secrets,&rdquo;
+ advised Bill. &ldquo;Those fellows are planning something, but I can't find out
+ what it is. They are suspicious of me, I think. But they are up to
+ something, and I believe, it would be best for you to leave while you have
+ the chance. It may not be healthy to stay. That's why I did my best to
+ untie you.&rdquo;
+ </p>
+ <p>
+ &ldquo;We appreciate what you have done,&rdquo; declared Mr. Jenks, &ldquo;but I want my
+ rights. I must learn a few more facts about how to make diamonds from
+ lightning flashes, and then I will have the same secret they cheated me
+ out of. I think if we wait a while we may be able to see the parts of the
+ process that are not quite clear to us. What do you say, Tom Swift?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I would like to learn the secret,&rdquo; replied the lad, &ldquo;and if Bill
+ thinks it's safe to stay here a while longer&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I guess it will be safe enough,&rdquo; was the reply. &ldquo;Those fellows won't
+ bother about you now that they are about to make some more diamonds.
+ Besides, they think you're all tied up. Yes, you can stay here and watch,
+ I reckon. I've got a couple of guns, and&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'll stay,&rdquo; decided Tom. &ldquo;We can put up a better fight now.&rdquo;
+ </p>
+ <p>
+ Silently, in their prison, but which they could now leave whenever they
+ pleased, the adventurers watched the diamond makers once more. The same
+ process they had witnessed before was gone through with. The white balls
+ were put inside the steel box and sealed up. Then they waited for the
+ storm to reach its height.
+ </p>
+ <p>
+ That this would not be long was evidenced by the mutterings of thunder
+ which every moment grew louder. The outburst of electrical fury was likely
+ to take place momentarily, and that it would be unusually severe was shown
+ by the precautions taken by the diamond makers. They attached a number of
+ extra wires, and brought out some insulated, hard rubber platforms, on
+ which they themselves stood. Tom and Mr. Jenks were much interested in
+ watching this detail of the work, and sought to learn how each part of the
+ process was done.
+ </p>
+ <p>
+ &ldquo;I almost think we can make diamonds, Tom, when we get back to
+ civilization,&rdquo; whispered Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I hope we can,&rdquo; answered Tom, &ldquo;and we can't get back any too soon to suit
+ me. I want to be in my airship again.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't blame you. But look, they are getting ready to adjust the
+ switch.&rdquo;
+ </p>
+ <p>
+ The adventurers ceased their whispered talk, and eagerly watched the
+ diamond makers. Folwell and Munson were hurrying to and fro in the big
+ cave, attending to the adjustments of the machinery.
+ </p>
+ <p>
+ &ldquo;On your insulated plates&mdash;all of you,&rdquo; Folwell gave the order. &ldquo;This
+ is going to be a terrific storm. The gage shows twice the power we have
+ ever used, and it's creeping up every minute! We'll have more diamonds
+ than ever had before!&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, if the mountain isn't destroyed,&rdquo; added Mr. Parker, in a low voice.
+ &ldquo;I predict that it will be split from top to bottom!&rdquo;
+ </p>
+ <p>
+ &ldquo;Comforting,&rdquo; thought Tom, grimly.
+ </p>
+ <p>
+ &ldquo;I guess we're all ready,&rdquo; said Folwell, in a low tone to Munson. &ldquo;We'd
+ better get insulated ourselves. I'm going to throw the switch.&rdquo;
+ </p>
+ <p>
+ He did so. A moment later the man who had before given warning of the
+ storm came dashing in. He was very much excited.
+ </p>
+ <p>
+ &ldquo;It's awful!&rdquo; he cried. &ldquo;The lightning is striking all over! Big rocks are
+ being split like logs of wood!&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it can't do any damage in here,&rdquo; said Munson. &ldquo;We are well
+ protected. Get on one of the plates,&rdquo; and he motioned to one of the
+ hard-rubber platforms that was not occupied. The roar and rumble of the
+ storm outside had given place to short terrific crashes. In their small
+ cave the adventurers could feel the solid ground shake.
+ </p>
+ <p>
+ A bluish light began dancing about the electrical wires. There was a smell
+ of sulphur in the air. Crash after crash resounded outside. A flash of
+ flame lit up the whole interior of the cave. It came from the copper
+ switch.
+ </p>
+ <p>
+ &ldquo;Something's wrong with the insulation!&rdquo; cried Munson.
+ </p>
+ <p>
+ &ldquo;Don't go near it!&rdquo; yelled Folwell. &ldquo;If you value your life, stand still!&rdquo;
+ </p>
+ <p>
+ Hardly had he spoken than inside the cavern there sounded a report like
+ that of a small cannon. A big ball of fire danced about the middle of the
+ cave and then leaped on top of the steel box.
+ </p>
+ <p>
+ &ldquo;This is a fearful storm,&rdquo; cried Munson.
+ </p>
+ <p>
+ The adventurers in the cave did not know what to say or do. They were in
+ deadly peril.
+ </p>
+ <p>
+ Suddenly there came a crash louder than any that had preceded it. The
+ whole side of the cave where the switches were was a mass of bluish flame.
+ Then came a ripping, tearing sound, and a tangle of wires and copper
+ connections were thrown to the floor. At the same time the steel box,
+ containing the materials from which diamonds were made, turned blue, and
+ flames shot from it.
+ </p>
+ <p>
+ &ldquo;It's all up with us!&rdquo; cried Munson. &ldquo;Run for it, everybody! The wires are
+ down, and this place will be an electric furnace in another minute!&rdquo;
+ </p>
+ <p>
+ He leaped toward the exit from the cave.
+ </p>
+ <p>
+ &ldquo;What about those fellows?&rdquo; asked Folwell, indicating the place where Tom
+ and the others had been tied.
+ </p>
+ <p>
+ &ldquo;They'll have to do the best they can! It's every man for himself, now!&rdquo;
+ yelled Munson. There was a wild scramble from the cavern.
+ </p>
+ <p>
+ &ldquo;Come on!&rdquo; cried Tom. &ldquo;We must escape! It's our only chance!&rdquo;
+ </p>
+ <p>
+ He leaped into the big cave, followed by the others. Already long tongues
+ of electrical fire were shooting out from the walls and roof as Tom Swift
+ and his companions, evading them as best they could, sought safety in
+ flight.

+ <h2>
+ CHAPTER XXV&mdash;THE MOUNTAIN SHATTERED&mdash;CONCLUSION
+ </h2>
+ <p>
+ &ldquo;Can't we get some of the diamonds?&rdquo; cried Mr. Damon, as he raced along
+ behind Tom. &ldquo;Now's our chance. Those fellows have all gone!&rdquo; The odd man
+ made a grab for something as he ran.
+ </p>
+ <p>
+ &ldquo;It's as much as our lives are worth,&rdquo; declared the young inventor. &ldquo;We
+ dare not stop! Come on!&rdquo;
+ </p>
+ <p>
+ &ldquo;I'd like to investigate some of the machinery,&rdquo; spoke Mr. Jenks, &ldquo;but I
+ wouldn't stop, even for that.&rdquo;
+ </p>
+ <p>
+ &ldquo;The storm is too dangerous,&rdquo; called Bill Renshaw. &ldquo;I can show you a
+ shorter way out than the one those fellows have taken. Follow me.&rdquo;
+ </p>
+ <p>
+ &ldquo;No way can be too short,&rdquo; said Mr. Parker, solemnly. &ldquo;This mountain will
+ go to pieces shortly, I think!&rdquo;
+ </p>
+ <p>
+ Tom shuddered. He remembered how narrow had been their escape when
+ Earthquake Island sank into the sea. And that some terrific upheaval was
+ now imminent might be judged from the awful reports that sounded more
+ plainly as the adventurers raced toward the opening of the cave. It was
+ like the bombardment of some doomed city.
+ </p>
+ <p>
+ Mr. Jenks and Tom cast one longing look behind at the complicated and
+ expensive machinery that had been installed in the cave by the diamond
+ makers. They had abandoned it, and in it lay the secret of making precious
+ gems. But there was no time to stop now, and investigate.
+ </p>
+ <p>
+ &ldquo;This way,&rdquo; urged Bill Renshaw. &ldquo;We'll soon be out.&rdquo;
+ </p>
+ <p>
+ &ldquo;But won't it be dangerous to go outside?&rdquo; asked Mr. Damon. &ldquo;Shan't we be
+ struck by lightning? There is some protection in here.&rdquo;
+ </p>
+ <p>
+ &ldquo;None at all,&rdquo; said Mr. Parker, quickly. &ldquo;This mountain is a natural
+ lightning rod. To stay here in this cave will be sure death when the storm
+ gets directly over it. And that will be very soon. We must get on
+ insulated ground. Is there any part of this mountain that does not contain
+ iron ore?&rdquo; the scientist asked of the former spirit.
+ </p>
+ <p>
+ &ldquo;Yes; the way out by which we are going lands on a dirt hill.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's good; then we may be saved.&rdquo;
+ </p>
+ <p>
+ On they ran. They had no lanterns, but the blue light of the electricity,
+ as it leaped from point to point inside the cave, where there were
+ outcroppings of iron ore, made the place bright enough to see.
+ </p>
+ <p>
+ &ldquo;Here we are!&rdquo; cried Bill Renshaw at length. &ldquo;Here's the way out!&rdquo;
+ </p>
+ <p>
+ Making a sudden turn in the winding passage he showed the adventurers a
+ small opening in the side of the crag. In an instant they had passed
+ through, and found themselves in daylight once more. The sudden glare
+ almost blinded them, for, though the sky was overcast by clouds, from
+ which jagged tongues of lightning played, the outside was much lighter
+ than the dark cave.
+ </p>
+ <p>
+ &ldquo;I should say it was a storm!&rdquo; cried Tom Swift. &ldquo;See, it is striking every
+ minute, and all around us!&rdquo;
+ </p>
+ <p>
+ In fact, lightning bolts were falling on every side of the adventurers.
+ Every time the balls of fire struck, they burst open great stones, or
+ seared a livid scar on the face of some cliff. As for Tom and the others,
+ they stood on a dry dirt hill, in which, fortunately, there was no iron
+ ore. To this fact they undoubtedly owed their lives, though had there been
+ rain, to moisten the ground and make the earth a good conductor of
+ electricity, they probably would have been badly shocked. But the
+ electrical outburst was not accompanied by rain.
+ </p>
+ <p>
+ Tom looked up. He saw a compact mass of cloud moving toward the summit of
+ the mountain on the slope of which they stood. From this cloud there
+ played shafts of reddish-green fire.
+ </p>
+ <p>
+ &ldquo;Look!&rdquo; called the young inventor to Mr. Parker. The instant the latter
+ saw the cloud, he cried:
+ </p>
+ <p>
+ &ldquo;We must get away from here by all means! That is the center of the storm.
+ As soon as it gets over the mountain, where that lightning rod is, all the
+ electrical fluid will be discharged in one bolt at the mountain, and it
+ will be destroyed! We must run, but keep on the dirt places! Run for your
+ lives!&rdquo;
+ </p>
+ <p>
+ They needed no second warning. Turning, they fled down the steep side of
+ the mountain, slipping and stumbling, but taking care not to step on any
+ iron ore. Behind them flashed the lightning bolts.
+ </p>
+ <p>
+ Suddenly there was a most awful crash. It seemed as if the end of the
+ world had come, and the ear drums of Tom and his companion almost burst
+ with the fearful report. The concussion knocked them down, and they lay
+ stunned for a moment.
+ </p>
+ <p>
+ Following the terrible report there was a low, rumbling sound. Hardly
+ knowing whether he was dead or alive, Tom opened his eyes and looked about
+ him. What he saw caused him to cry out in terror.
+ </p>
+ <p>
+ The whole mountain seemed bathed in fire. Great blue, red and green
+ flashes played around it. Then the towering cliff seemed to melt and
+ crumble up, and the great peak, the top of it containing the diamond
+ makers' cave, from which they had fled but a few minutes before, the
+ entire summit was toppled over into the valley on the other side, and in
+ the direction opposite to that where the adventurers stood.
+ </p>
+ <p>
+ Then came a profound silence, and the lightning ceased. The storm was
+ over, and only the rattle of stones and boulders, as they came to rest in
+ the valley below, reached the ears of our friends.
+ </p>
+ <p>
+ &ldquo;Phantom Mountain has been destroyed, just as I said it would be,&rdquo; spoke
+ Mr. Parker, solemnly. Once more he had prophesied correctly.
+ </p>
+ <p>
+ For a few minutes the adventurers hardly knew what to say. They arose
+ awkwardly from the ground where the shock had tossed them. Then Tom
+ remarked, as calmly as possible:
+ </p>
+ <p>
+ &ldquo;Well, it's all over. I guess we may as well get back to our airship.&rdquo;
+ </p>
+ <p>
+ &ldquo;What became of Munson and the others?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ Mr. Jenks pointed to the trail, far below. The figures of some men,
+ running madly, could be seen.
+ </p>
+ <p>
+ &ldquo;There they go,&rdquo; he said; &ldquo;I fancy we have seen the last of them.&rdquo; And
+ they had, for some time at least.
+ </p>
+ <p>
+ There was little use lingering any longer on Phantom Mountain&mdash;indeed
+ little of it was left on which to remain. Looking back toward the place
+ where the cave had been, Tom and the others started forward again. The
+ diamond-making machinery had all been destroyed. So, also, had the
+ finished diamonds stored in the cavern and the large supply which had
+ probably been made by the last terrific crash. No one would ever have them
+ now. Tom and Mr. Jenks felt a sense of disappointment, but they were glad
+ to have escaped with their lives. They sought their former camp, but the
+ tent and all their food was buried under tons of earth and rocks.
+ </p>
+ <p>
+ Three days later, after rather severe hardships, they were near the place
+ where they had left the Red Cloud. They had suffered cold and hunger, for
+ they had no food supplies, and, had it not been that Bill Renshaw knew the
+ haunts of some game, of which they managed to snare some, they would have
+ fared badly, for they had left their guns in the cave.
+ </p>
+ <p>
+ &ldquo;Well, there are the trees behind which I hope my airship is hidden,&rdquo;
+ announced Tom, as they came to the spot. &ldquo;Good old Red Cloud! Maybe we
+ won't do some eating when we get aboard, eh?&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my appetite! but we certainly will!&rdquo; cried Mr. Damon.
+ </p>
+ <p>
+ &ldquo;There's somebody walking around the place,&rdquo; spoke Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I hope it's no one who has damaged the ship,&rdquo; came from Tom,
+ apprehensively. He broke into a run, and soon confronted an aged miner,
+ who seemed to have established a rude sort of camp near the airship.
+ </p>
+ <p>
+ &ldquo;Is anything the matter?&rdquo; asked Tom, breathlessly. &ldquo;Is my airship all
+ right?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess she's all right, stranger,&rdquo; was the reply. &ldquo;I don't know much
+ about these contraptions, but I haven't touched her. I knowed she was an
+ airship, for I've seen pictures of 'em, and I've been waiting until the
+ owner came along.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo; asked Tom, wonderingly.
+ </p>
+ <p>
+ &ldquo;Because I've got a proposition to make to you,&rdquo; went on the miner, who
+ said his name was Abe Abercrombie. &ldquo;I've been a miner for a good many
+ years, and I'm just back from Alaska, prospecting around here. I haven't
+ had any luck, but I know of a gold mine in Alaska that will make us all
+ rich. Only it needs an airship to get to it, and I've been figuring how to
+ hire one. Then I comes along, and I sees this big one, and I makes up my
+ mind to stay here until the owners come back. That's what I've done. Now,
+ if I prove that I'm telling the truth, will you go to Alaska&mdash;to the
+ valley of gold with me?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know,&rdquo; answered Tom, to whom the proposition was rather sudden.
+ &ldquo;We've just had some pretty startling adventures, and we're almost
+ starved. Wait until we get something to eat, and we'll talk. Come aboard
+ the Red Cloud,&rdquo; and the lad led the way to his craft which was in as good
+ condition as when he left it to go to the diamond cave. Later he listened
+ to the miner's story.
+ </p>
+ <p>
+ Tom Swift did go to the valley of gold in Alaska, and what happened to him
+ and his companions there will be told of in the next volume of this
+ series, to be called &ldquo;Tom Swift in the Caves of Ice; or, the Wreck of the
+ Airship.&rdquo;
+ </p>
+ <p>
+ It did not take our friends long, after they had eaten a hearty meal, to
+ generate some fresh gas, and start the Red Cloud on her homeward way. Tom
+ wanted to take Bill Renshaw with him, but the old man said he would rather
+ remain among the mountains where he had been born. So, after paying him
+ well for his services, they said good-by to him. Abercrombie, the miner,
+ also remained behind, but promised to call and see Tom in a few months.
+ </p>
+ <p>
+ &ldquo;Well, we didn't make any money out of this trip,&rdquo; observed Mr. Jenks,
+ rather dubiously, as they were nearing Shopton, after an uneventful trip.
+ &ldquo;I guess I owe you considerable, Tom Swift. I promised to get you a lot of
+ diamonds, but all I have are those I had from my first visit to the cave.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, that's all right,&rdquo; spoke Tom, easily. &ldquo;The experience was worth all
+ the trip cost.&rdquo;
+ </p>
+ <p>
+ &ldquo;Speaking of diamonds, look here!&rdquo; exclaimed Mr. Damon, suddenly, and he
+ pulled out a double handful.
+ </p>
+ <p>
+ &ldquo;Where did you get them?&rdquo; cried the others in astonishment.
+ </p>
+ <p>
+ &ldquo;I grabbed them up, as we ran from the cave,&rdquo; said the eccentric man;
+ &ldquo;but, bless my gaiters! I forgot all about them until you spoke. We'll
+ share them.&rdquo;
+ </p>
+ <p>
+ These diamonds, some of which were large, proved very valuable, though the
+ total sum was far below what Mr. Jenks hoped to make when he started on
+ the remarkable trip. Tom gave Mary Nestor a very fine stone, and it was
+ set in a ring, instead of a pin, this time.
+ </p>
+ <p>
+ On their arrival in Shopton, where Mr. Swift, the housekeeper, Mr. Jackson
+ and Eradicate Sampson were much alarmed for Tom's safety, an attempt was
+ made to manufacture diamonds, using a powerful electric current instead of
+ lightning. But it was not a success, and so Mr. Jenks concluded to give up
+ his search for the secret which was lost on Phantom Mountain.
+ </p>
+ <p>
+ And now we will take leave of Tom Swift, to meet him again soon in other
+ adventures he is destined to have in the caves of ice and the valley of
+ gold.

+CHAPTER I--A SUSPICIOUS JEWELER
+
+
+“Well, Tom Swift, I don't believe you will make any mistake if you buy
+that diamond,” said the jeweler to a young man who was inspecting a tray
+of pins, set with the sparkling stones. “It is of the first water, and
+without a flaw.”
+
+“It certainly seems so, Mr. Track. I don't know much about diamonds, and
+I'm depending on you. But this one looks to be all right.”
+
+“Is it for yourself, Tom?”
+
+“Er--no--that is, not exactly,” and Tom Swift, the young inventor of
+airships and submarines, blushed slightly.
+
+“Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I think she
+would like a pin of this sort. True, it's rather expensive, but--”
+
+“No, it isn't for Mrs. Baggert, Mr. Track,” and Tom seemed a bit
+embarrassed.
+
+“No? Well, then, Tom--of course it's none of my affair, except to
+sell you a good stone, But if this brooch is for a young lady, I can't
+recommend anything nicer. Do you think you will take this; or do you
+prefer to look at some others?”
+
+“Oh, I think this will do, Mr. Track. I guess I'll take--”
+
+Tom's words were interrupted by a sudden action on the part of the
+jeweler. Mr. Track ran from behind the showcase and hastened toward the
+front door.
+
+“Did you see him, Tom?” he cried. “I wonder which way he went?”
+
+“Who?” asked the lad, following the shopkeeper.
+
+“That man. He's been walking up and down in front of my place for the
+last ten minutes--ever since you've been in here, in fact, and I don't
+like his looks.”
+
+“What did he do?”
+
+“Nothing much, except to stare in here as if he was sizing my place up.”
+
+“Sizing it up?”
+
+“Yes. Getting the lay of the land, so he or some confederate could
+commit a robbery, maybe.”
+
+“A robbery? Do you think that man was a thief?”
+
+“I don't know that he was, Tom, and yet a jeweler has to be always
+on the watch, and that isn't a joke, either, Tom Swift. Swindlers and
+thieves are always on the alert for a chance to rob a jewelry store, and
+they work many games.”
+
+“I didn't notice any particular man looking in here,” said Tom, who
+still held the diamond brooch in his hand.
+
+“Well I did,” went on the jeweler. “I happened to glance out of the
+window when you were looking at the pins, and I saw his eyes staring in
+here in a suspicious manner. He may have a confederate with him, and,
+when you're gone, one may come in, and pretend to want to look at some
+diamonds. Then, when I'm showing him some, the other man will enter,
+engage my attention, and the first man will slip out with a diamond ring
+or pin. It's often done.”
+
+“You seem to have it all worked out, Mr. Track,” observed the lad, with
+a smile. “How do you know but what I'm in with a gang of thieves, and
+that I'm only pretending to want to buy a diamond pin?”
+
+“Oh, I guess I haven't known you, Tom Swift, ever since you were
+big enough to toddle, not to be sure about what you're up to. But I
+certainly didn't like the looks of that man. However, let's forget about
+him. He seems to have gone down the street, and, after all, perhaps I
+was mistaken. Just wait until I show you a few more styles before you
+decide. The young lady may like one of these,” and the jeweler went to
+another showcase and took out some more trays of brooches.
+
+“What makes you think she's a young lady, Mr. Track?” asked the lad.
+
+“Oh, it's easy guessing, Tom. We jewelers are good readers of character.
+I can size up a young fellow coming in here to buy an engagement or a
+wedding ring, as soon as he enters the door. I suppose you'll soon be
+in the market for one of those, Tom, if all the reports I hear about you
+are true--you and a certain Mary Nestor.”
+
+“I--er--I think I don't care for any of these pins,” spoke Tom, quickly,
+with a blush. “I like the first lot best. I think I'll take the one I
+had in my hand when that man alarmed you. Ha! That's odd! What did I do
+with it?”
+
+Tom looked about on the showcase, and glanced down on the floor. He had
+mislaid the brooch, but the jeweler, with a laugh, lifted it out of a
+tray a moment later.
+
+“I saw you lay it down,” he said. “We jewelers have to be on the watch.
+Here it is. I'll just put it in a box, and--”
+
+With an exclamation, Mr. Track gave a hasty glance toward his big show
+window. Tom looked up, and saw a man's face peering in. At the sight of
+it, he, too, uttered a cry of surprise.
+
+The next instant the man outside knocked on the glass, apparently with
+a piece of metal, making a sharp sound. As soon as he heard it, the
+jeweler once more sprang from behind the showcase, and leaped for the
+door crying:
+
+“There's the thief! He's trying to cut a hole through my show window and
+reach in and get something! It's an old trick. I'll get the police! Tom,
+you stay here on guard!” and before the lad could utter a protest, the
+jeweler had opened the door, and was speeding down the street in the
+gathering darkness.
+
+Tom stared about him in some bewilderment. He was left alone in charge
+of a very valuable stock of jewelry, the owner of which was racing after
+a supposed thief, crying:
+
+“Police! Help! Thieves! Stop him, somebody!”
+
+“This is a queer go,” mused Tom. “I wonder who that man was? He looked
+like somebody I know, and yet I can't seem to place his face. I
+wonder if he was trying to rob the place? Maybe there's another one--a
+confederate--around here.”
+
+This thought rather alarmed Tom, so he went to the door, and looked up
+and down the street. He could see no suspicious characters, but in the
+direction in which the jeweler was running there was a little throng of
+people, following Mr. Track after the man who had knocked on the window.
+
+“I wish I was there, instead of here,” mused the lad. “Still I can't
+leave, or a thief might come in. Perhaps that was the game, and one of
+the gang is hanging around, hoping the store will be deserted, so he can
+enter and take what he likes.”
+
+Tom had read of such cases, and he at once resolved that he would not
+only remain in the jewelry shop, but that he would lock the door, which
+he at once proceeded to do. Then he breathed easier.
+
+The town of Shopton, in the outskirts of which Tom lived with his
+father, and where the scene above narrated took place, was none too well
+lighted at night, and the lad had his doubts about the jeweler catching
+the oddly-acting man, especially as the latter had a good start.
+
+“But some one may head him off,” reasoned Tom. “Though if they do catch
+him, I don't see what they can prove against him. Hello, here I am
+carrying this diamond pin around. I might lose it. Guess I'll put it
+back on the tray.”
+
+He replaced in the proper receptacle one of the pins he had been
+examining when the excitement occurred.
+
+“I wonder if Mary will like that?” he said, softly. “I hope she does.
+Perhaps it would be better if she could come here herself and pick out
+one--”
+
+Tom's musing was suddenly interrupted by a sharp tattoo on the glass
+door of the jewelry shop. With a start, he looked up, to see staring in
+on him the face of the man who had been there before--the man of whom
+the jeweler was even then in chase.
+
+“Why--why----” stammered Tom.
+
+The man knocked again.
+
+“Tom--Tom Swift!” he called. “Don't you know me?”
+
+“Know you--you?” repeated the lad.
+
+“Yes--don't you remember Earthquake Island--how we were nearly killed
+there--don't you remember Mr. Jenks?”
+
+“Mr. Jenks?”
+
+Tom was so startled that he could only repeat words after the strange
+man, who was talking to him from outside the glass door.
+
+“Yes, Mr. Jenks,” was the reply. “Mr. Barcoe Jenks, who makes diamonds.
+I saw you in the store about to buy a diamond--I wanted to tell you not
+to--I'll give you a better diamond than you can buy--I just arrived in
+this place--I must have a private talk with you--Come out--I'll share a
+wonderful secret with you.”
+
+A flood of memory came to Tom. He did recall the very strange man who
+walked around Earthquake Island--where Tom and some friends had been
+marooned recently--walked about with a pocketful of what he said were
+diamonds. Now Barcoe Jenks was here.
+
+“I must see you privately, Tom Swift,” went on Mr. Jenks, as he once
+more tapped on the glass. “Don't waste money buying diamonds, when you
+and I can make better ones. Where can I have a talk with you? I--” Mr.
+Jenks suddenly looked down the dimly-lighted street. “They're coming
+back!” he cried. “I don't want to be seen. I'll call at your house later
+to-night--be on the watch for me--until then--good-by!”
+
+He waved his hand, and was gone in an instant. Tom stood staring at the
+glass door. He hardly knew whether to believe it or not--perhaps it was
+all a dream.
+
+He pinched himself to make sure that he was awake. Very substantial
+flesh met his thumb and finger, and he felt the pain.
+
+“I'm awake all right,” he murmured. “But Barcoe Jenks here--and still
+talking that nonsense about his manufactured diamonds. I think he must
+be crazy. I wonder--”
+
+Once more the lad's musing was interrupted. He heard a murmur of excited
+voices outside the store, on the street. Then the door of the jewelry
+shop was tried. Mr. Track's face was pressed against the glass.
+
+“Open the door! Let me in, Tom!” he called. “I've caught the thief,” and
+as the lad unlocked the portal he saw that the jeweler held by the arm
+a ragged lad. “Ah; you scoundrel! I've caught you!” cried the diamond
+merchant, shaking the small chap, while Tom looked on, more mystified
+than ever.
+
+
+
+
+CHAPTER II--A MIDNIGHT VISIT
+
+
+While Mr. Track, the jeweler, and several citizens, attracted by the
+chase after the supposed thief, are crowded into the store, anxious to
+hear explanations of the strange affair, I will take the opportunity to
+tell you something of Tom Swift, the lad who is to figure in this story.
+
+Many of you have already made his acquaintance, when he has been
+speeding about in his airship or fast electric runabout, and to others
+we will state that our hero first made his bow to the public in the
+book called “Tom Swift and His Motor-Cycle,” the initial volume of this
+series.
+
+In that story there was related how Tom made the acquaintance of an
+odd individual, named Mr. Wakefield Damon, who was continually blessing
+himself, some part of his anatomy, or his possessions. Mr. Damon was
+riding a motor-cycle, and it started to climb a tree, to his pain and
+fright. Afterward Tom purchased the machine, and had many adventures
+on it, including a chase after a gang of men who had stolen a valuable
+patent model belonging to Mr. Swift.
+
+Mr. Swift and his son were both inventors. They lived together in a
+fine house in the suburbs of Shopton, New York, and with them dwelt Mrs.
+Baggert, the housekeeper (for Tom's mother was dead), and also Garret
+Jackson, an expert engineer, who aided the young inventor and his father
+in perfecting many machines.
+
+There was also another semi-member of the household, to wit, Eradicate
+Sampson, an eccentric colored man, who owned a mule called Boomerang.
+Eradicate did odd jobs around the place, and the mule assisted his
+owner--that is when the mule felt like it.
+
+In the second volume of the series, entitled “Tom Swift and His
+Motor-Boat,” there was related the incidents following a pursuit after
+a gang of unprincipled men, who sought to get possession of some of Mr.
+Swift's patents, and it was while in this boat that Tom, his father, and
+a friend, Ned Newton, rescued from Lake Carlopa a Mr. John Sharp, who
+fell from his burning balloon. Mr. Sharp was a skilled aeronaut, and
+after his recovery he joined Tom in building a big airship, called the
+Red Cloud. Tom's adventures in this craft are set down in detail in the
+third volume of the series, called “Tom Swift and His Airship.” Not only
+did he and Mr. Sharp and Mr. Damon make a great trip, but they captured
+some bank robbers, and incidentally cleared themselves from the
+imputation of having looted the vault of seventy-five thousand dollars,
+which charge was fostered by a certain Mr. Foger, and his son Andy, who
+was Tom's enemy.
+
+Not satisfied with having conquered the air, Tom and his father set
+to work to gain a victory over the ocean. They built a boat that could
+navigate under water, and, in the fourth book of the series, called “Tom
+Swift and His Submarine Boat,” you will find an account of how they went
+under the ocean to secure a sunken treasure, and the fight they had with
+their enemies who sought to get it away from them. They went through
+many perils, not the least of which was capture by a foreign warship.
+
+In the fifth book, entitled “Tom Swift and His Electric Runabout,” there
+was told the story of a wonderfully speedy electric automobile the young
+inventor constructed, and how he made a great race in it, and saved from
+ruin a bank, in which his father and Mr. Damon were interested.
+
+Tom's ability as an inventor had, by this time, become well known. One
+day, as related in a volume called “Tom Swift and His Wireless Message,”
+ he received a letter from a Mr. Hosmer Fenwick, of Philadelphia, asking
+his aid in perfecting an airship which the resident of the Quaker
+City had built, but which would not work. In his small monoplane, the
+Butterfly, Tom and Mr. Damon went to Philadelphia, as Mr. Damon was
+acquainted with Mr. Fenwick.
+
+Tom carefully inspected the Whizzer which was the name of Mr. Fenwick's
+airship, and, after some difficulties, succeeded in getting the electric
+craft in shape to make a flight.
+
+Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape May in the
+Whizzer, but were caught in a terrific storm, and blown out to sea.
+The wind became a hurricane, the airship was disabled, and wrecked in
+mid-air. When it fell to earth it landed on one of the small West Indian
+islands, but what was the terror of the three castaways to find that the
+island was subject to earthquake shocks.
+
+But the earth-tremors were not the only surprise in store for Tom and
+his two friends, On the island they found five men and two ladies, who,
+by strange chance, had been stranded there when the yacht Resolute,
+owned by Mr. George Hosbrook, was wrecked in the same storm that
+disabled the airship. Mr. Hosbrook, a millionaire, was taking a party of
+friends to the West Indies.
+
+When the castaways (among whom were Mr. and Mrs. Amos Nestor, parents
+of Mary Nestor, a girl of whom Tom was very fond) found that there was
+danger of the island being destroyed in an earthquake, they were in
+despair. There seemed no way of being rescued, as the island was out of
+the line of regular ship travel.
+
+Tom, however, was resourceful. With the electrical apparatus from the
+wrecked airship, he built a wireless plant, and sent messages for help,
+broadcast over the ocean.
+
+They were finally heard, and answered, by an operator on board the
+steamer Camberanian, which came on under forced draught, and rescued
+Tom and his friends. It was only just in time, for, no sooner had
+they gotten aboard the steamer in lifeboats, than the whole island was
+destroyed by an earthquake shock.
+
+But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the
+others, got safely home. Among the survivors from the yacht Resolute
+was a Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom
+through the glass window of the jewelry store. Mr. Jenks was a peculiar
+man. Tom discovered this on Earthquake Island. Mr. Jenks carried with
+him some stones which he said were diamonds. He asserted that he had
+made them, but Tom did not know whether or not to believe this.
+
+When it seemed that the castaways would not be saved Mr. Jenks offered
+Tom a large sum in these same diamonds for some plan whereby he might
+escape the earthquakes. Mr. Jenks said there was a certain secret in
+connection with the manufactured diamonds that he had to solve--that he
+had been defrauded of his rights--and that a certain Phantom Mountain
+figured in it. But Tom, at that time, paid little attention to Mr.
+Jenks' talk. The time was to come, however, when he would attach much
+importance to it.
+
+When this story opens, Tom was more interested in Mr. Barcoe Jenks than
+in any one else, and was wondering what he wanted to see him about. The
+young inventor could not quite understand how Mr. Track, the jeweler,
+could come back with a lad he suspected of being a thief, when the
+person who had acted so suspiciously, and who had knocked on the glass,
+was the queer man, Mr. Jenks.
+
+“Yes, Tom I caught him,” the jeweler went on. “I chased after him, and
+nabbed him. It was hard work, too, for I'm not a good runner. Now, you
+little rascal, tell me why you tried to rob my store?” and the diamond
+merchant shook the lad roughly.
+
+“I--I didn't try to rob your store,” was the timid answer.
+
+“Well, perhaps you didn't, exactly, but your confederates did. Why did
+you rap on the glass, and why were you staring in so intently?”
+
+“I wasn't lookin' in.”
+
+“Well, if it wasn't you, it was some one just like you. But why did you
+run when I raced down the street?”
+
+“I--I don't know,” and the lad began to snivel. “I--I jest ran--that's
+all--'cause I see everybody else runnin', an' I thought there was a
+fire.”
+
+“Ha! That's a likely story! You ran because you are guilty! I'm going to
+hand you over to the police.”
+
+“Did he get anything, Mr. Track?” asked one of the men who had joined
+the jeweler in the chase.
+
+“No, I can't say that he did. He didn't get a chance. Tom Swift was
+in here at the time. But this fellow was only waiting for a chance to
+steal, or else to aid his confederates.”
+
+“But, if he didn't take anything, I don't see how you can have him
+arrested,” went on the man.
+
+“On suspicion; that's how!” asserted Mr. Track. “Will some one get me a
+constable?”
+
+“I wouldn't call a constable,” said Tom, quietly.
+
+“Why not?”
+
+“Because that isn't the person who looked in your window.”
+
+“How do you know, Tom?”
+
+“Because that person came back while you were out. I saw him.”
+
+“You saw him? Did he try to steal any of my diamonds, Tom?”
+
+“No, I guess he doesn't need any.”
+
+“Why not?” There was wonder in the jeweler's tone.
+
+“Why, he claims he can make all he wants.”
+
+“Make diamonds?”
+
+“So he says.”
+
+“Why, he must be crazy!” and Mr. Track laughed.
+
+“Perhaps he is,” admitted Tom, “I'm only telling you what he says. He's
+the person who acted so suspiciously. He came back here, I'm telling
+you, while you were running down the street, and spoke to me.”
+
+“Oh, then you know him?” The jeweler's voice was suspicious.
+
+“I didn't at first,” admitted Tom. “But when he said he was Mr.
+Barcoe Jenks, I remembered that I had met him when I was cast away on
+Earthquake Island.”
+
+“And he says he can make diamonds?” asked Mr. Track.
+
+“What did he want of you?” and the jeweler looked at Tom, quizzically.
+
+“He wanted to have a talk with me,” replied the lad, “and when he saw
+me in your store, he tried to attract my attention by knocking on the
+glass.”
+
+“That's a queer way to do,” declared Mr. Track. “What did he want?”
+
+“I don't know exactly,” answered Tom, not caring to go into details just
+then. “But I'm sure, Mr. Track, that you've got the wrong person there.
+That lad never looked in the window, nor knocked on the glass.”
+
+“That's right--I didn't,” asserted the captive.
+
+The jeweler looked doubtful.
+
+“Why did you run?” he asked.
+
+“I told you, I thought there was a fire.”
+
+“That's right, I don't believe he's the fellow you want,” put in another
+man. “I was standing on the corner, near White's grocery store, and
+I noticed this lad. That was before I heard you yelling, and saw you
+coming, and then I joined in the chase. I guess the man you were after
+got away, Track.”
+
+“He did,” asserted Tom. “He came back here, a little while ago, and he
+ran away just now, as he heard you coming.”
+
+“Where did he go?” asked the jeweler, eagerly.
+
+“I don't know,” answered Tom. “Only you've got the wrong lad here.”
+
+“Well, perhaps I have,” admitted the diamond merchant. “You can go,
+youngster, but next time, don't run if you're not guilty.”
+
+“I thought there was a fire,” repeated the lad, as he hurriedly slipped
+through the crowd in the store, and disappeared down the dark street.
+
+“Well, I guess the excitement's all over, and, anyhow, you weren't
+robbed, Track,” said a stout man, as he left the store. The others soon
+followed, and Tom and the jeweler were once more alone in the shop.
+
+“Can you tell me something about this man, Tom?” asked Mr. Track,
+eagerly. “So he really makes diamonds. Who is he?”
+
+“I'd rather not tell--just now,” replied the young inventor. “I don't
+take much stock in him, myself. I think he's visionary. He may think he
+has made diamonds, and he may have made some stones that look like them.
+I'm very skeptical.”
+
+“If you could bring me some, Tom, I could soon tell whether they were
+real or not. Can you?”
+
+The lad shook his head.
+
+“I don't expect to see Mr. Jenks again,” he said. “He talked
+rather wildly about waiting to meet me, but that man is odd--crazy,
+perhaps--and I don't imagine I'll see him. He's harmless, but he's
+eccentric. Well, there was quite some excitement for a time.”
+
+“I should say there was. I thought it was a plan to rob me,” and the
+jeweler began putting away the diamond pins. In fact, the excitement
+so filled the minds of himself and Tom that neither of them thought any
+more of the object of the lad's visit, and the young inventor departed
+without purchasing the pin he had come after.
+
+It was not until he was out on the street, walking toward his home, that
+the matter came back to his mind.
+
+“I declare!” he exclaimed. “I didn't get that pin for Mary, after all!
+Well, never mind, I have a week until her birthday, and I can get it
+to-morrow.”
+
+He walked rapidly toward home, for the weather looked threatening, and
+Tom had no umbrella. He was musing on the happenings of the evening when
+he reached his house. His father was out, as was Garret Jackson, the
+engineer; and Mrs. Baggert, the housekeeper, was entertaining a lady in
+the sitting-room, so, as Tom was rather tired, he went directly to his
+own room, and, a little later got into bed.
+
+It was shortly after midnight when he was awakened by hearing a rattling
+on the window of his room. The reason he was able to fix the time
+so accurately was because as soon as he awakened he pressed a little
+electric button, and it illuminated the face of a small clock on his
+bureau. The hands pointed to five minutes past twelve.
+
+“Humph! That sounds like hail!” exclaimed Tom, as he arose, and looked
+out of the casement. “I wonder if any of the skylights of the airship
+shed are open? There might be some damage. Guess I'd better go out and
+take a look.”
+
+He had mentally reasoned this far before he had looked out, and when
+he saw that the moon was brightly shining in a clear sky, he was a bit
+surprised.
+
+“Why--that wasn't hail,” he murmured. “It isn't even raining. I wonder
+what it was?”
+
+He was answered a moment later, for a shower of fine gravel from the
+walk flew up and clattered against the glass. With a start, Tom looked
+down, and saw a dark figure standing under an apple tree.
+
+“Hello! Who's there?” called the lad, after he had raised the sash.
+
+“It's I--Mr. Jenks,” was the surprising answer.
+
+“Mr. Jenks?” repeated Tom.
+
+“Yes--Barcoe Jenks, of Earthquake Island.”
+
+“You here? What do you want?”
+
+“Can you come down?”
+
+“What for?”
+
+“Tom Swift, I've something very important to tell you,” was the answer
+in a low voice, yet which carried to Tom's ears perfectly. “Do you want
+to make a fortune for yourself--and for me?”
+
+“How?” Tom was beginning to think more and more that Mr. Jenks was
+crazy.
+
+“How? By helping me to discover the secret of Phantom Mountain, where
+the diamonds are made! Will you?”
+
+“Wait a minute--I'll come down,” answered Tom, and he began to grope for
+his clothes in the dim light of the little electric lamp.
+
+What was the secret of Phantom Mountain? What did Mr. Jenks really want?
+Could he make diamonds? Tom asked himself these questions as he hastily
+dressed to go down to his midnight visitor.
+
+
+
+
+CHAPTER III--A STRANGE STORY
+
+
+“Well, Mr. Jenks,” began Tom, when he had descended to the garden, and
+greeted the man who had acted so strangely on Earthquake Island, “this
+is rather an odd time for a visit.”
+
+“I realize that, Tom Swift,” was the answer, and the lad noticed that
+the man spoke much more calmly than he had that evening at the jewelry
+shop. “I realize that, but I have to be cautious in my movements.”
+
+“Why?”
+
+“Because there are enemies on my track. If they thought I was seeking
+aid to discover the secret of Phantom Mountain, my life might pay the
+forfeit.”
+
+“Are you in earnest, Mr. Jenks?”
+
+“I certainly am, and, while I must apologize for awakening you at this
+unseemly hour, and for the mysterious nature of my visit, if you will
+let me tell my story, you will see the need of secrecy.”
+
+“Oh, I don't mind being awakened,” answered Tom, good-naturedly, “but
+I will be frank with you, Mr. Jenks. I hardly can believe what you have
+stated to me several times--that you know how diamonds can be made.”
+
+“I can prove it to you,” was the quiet answer.
+
+“Yes, I know. For centuries men have tried to discover the secret of
+transmuting base metals into gold, and how to make diamonds by chemical
+means. But they have all been failures.”
+
+“All except this process--the process used at Phantom Mountain,”
+ insisted the queer man. “Do you want to hear my story?”
+
+“I have no objections.”
+
+“Then let me warn you,” went on Mr. Jenks, “that if you do hear it, you
+will be so fascinated by it that I am sure you will want to cast your
+lot in with mine, and aid me to get my rights, and solve the mystery.
+And I also want to warn you that if you do, there is a certain amount of
+danger connected with it.”
+
+“I'm used to danger,” answered Tom, quietly. “Let me hear your story.
+But first explain how you came to come here, and why you acted so
+strangely at the jewelry store.”
+
+“Willingly. I tried to attract your attention at the store, because I
+saw that you were going to buy a diamond, and I didn't want you to.”
+
+“Why not?”
+
+“Because I want to present you with a beautiful stone, that will answer
+your purpose as well or better, than any one you could buy. That will
+prove my story better than any amount of words or argument. But I could
+not attract your attention without also attracting that of the jeweler.
+He became suspicious, gave chase, and I thought it best to vanish. I
+hope no one was made to suffer for what may have been my imprudence.”
+
+“No, the lad whom Mr. Track caught was let go. But how did you happen to
+come to Shopton?”
+
+“To see you. I got your address from the owner of the yacht Resolute. I
+knew that if there was one person who could aid me to recover my rights,
+it would be you, Tom Swift. Will you help me? Will you come with me to
+discover the secret of Phantom Mountain? If we go, it will have to be in
+an airship, for in no other way, I think, can we come upon the place, as
+it is closely guarded. Will you come? I will pay you well.”
+
+“Perhaps I had better hear your story,” said the young inventor. “But
+first let me suggest that we move farther away from the house. My
+father, or Mr. Jackson, or the housekeeper, may hear us talking, and it
+may disturb them. Come with me to my private shop,” and Tom led the way
+to a small building where he did experimental work. He unlocked the door
+with a key he carried, turned on the lights, which were run by a storage
+battery, and motioned Mr. Jenks to a seat.
+
+“Now I'll hear your story,” said Tom.
+
+“I'll make it as short as possible,” went on the queer man. “To begin
+with, it is now several years ago since a poorly dressed stranger
+applied to me one night for money enough to get a meal and a bed to
+sleep in. I was living in New York City at the time, and this was
+midnight, as I was returning home from my club.
+
+“I was touched by the man's appearance, and gave him some money. He
+asked for my card, saying he would repay me some day. I gave it to him,
+little thinking I would hear from the man again. But I did. He called
+at my apartments about a week later, saying he had secured work as an
+expert setter of diamonds, and wanted to repay me. I did not want to
+take his money, but the fact that such a sorry looking specimen of
+manhood as he had been when I aided him, was an expert handler of gems
+interested me. I talked with the man, and he made a curious statement.
+
+“This man, who gave his name as Enos Folwell, said he knew a place where
+diamonds could be made, partly in a scientific manner, and partly by the
+forces of nature. I laughed at him, but he told me so many details that
+I began to believe him. He said he and some other friends of his, who
+were diamond cutters, had a plant in the midst of the Rocky Mountains,
+where they had succeeded in making several small, but very perfect
+diamonds. They had come to the end of their rope, though, so to speak,
+because they could not afford to buy the materials needed. Folwell
+said that he and his companions had temporarily separated, had left the
+mountain where they made diamonds, and agreed to meet there later when
+they had more money with which to purchase materials. They had all
+agreed to go out into civilization, and work for enough funds to enable
+them to go on with their diamond making.
+
+“I hardly knew whether to believe the man or not, but he offered proof.
+He had several small, but very perfect diamonds with him, and he gave
+them to me, to have tested in any way I desired.
+
+“I promised to look into the matter, and, as I was quite wealthy, as,
+in fact I am now, and if I found that the stones he gave me were real, I
+said I might invest some money in the plant.”
+
+“Were the diamonds good?” asked Tom, who was beginning to be interested.
+
+“They were--stones of the first water, though small. An expert gem
+merchant, to whom I took them, said he had never seen any diamonds like
+them, and he wanted to know where I got them. Of course I did not tell
+him.
+
+“To make a long story short, I saw Folwell again, told him to
+communicate with his companions, and to tell them that I would agree to
+supply the cash needed, if I could share in the diamond making. To this
+they agreed, and, after some weeks spent in preparation, a party of us
+set out for Phantom Mountain.”
+
+“Phantom Mountain?” interrupted Tom. “Where is it?”
+
+“I don't know, exactly--it's somewhere in the Rockies, but the exact
+location is a mystery. That is why I need your help. You will soon
+understand the reason. Well, as I said, myself, Folwell and the others,
+who were not exactly prepossessing sort of men, started west. When we
+got to a small town, called Indian Ridge, near Leadville, Colorado,
+the men insisted that I must now proceed in secret, and consent to be
+blindfolded, as they were not yet ready to reveal the secret of the
+place where they made the diamonds.
+
+“I did not want to agree to this, but they insisted, and I gave in,
+foolishly perhaps. At any rate I was blindfolded one night, placed in
+a wagon, and we drove off into the mountains. After traveling for some
+distance I was led, still blindfolded, up a steep trail.
+
+“When the bandage was taken off my eyes I saw that I was in a large
+cave. The men were with me, and they apologized for the necessity that
+caused them to blindfold me. They said they were ready to proceed with
+the making of diamonds, but I must promise not to seek to discover the
+secret until they gave me permission, nor was I to attempt to leave the
+cave. I had to agree.
+
+“Next they demanded that I give them a large sum, which I had promised
+when they showed me, conclusively, that they could make diamonds. I
+refused to do this until I had seen some of the precious stones, and
+they agreed that this was fair, but said I would have to wait a few
+days.
+
+“Well, I waited, and, all that while, I was virtually a prisoner in the
+cave. All I could learn was that it was in the midst of a great range,
+near the top, and that one of the peaks was called Phantom Mountain.
+Why, I did not learn until later.
+
+“At last one night, during a terrific thunder storm, the leader of the
+diamond makers--Folwell--announced that I could now see the stones made.
+The men had been preparing their chemicals for some days previous. I
+was taken into a small chamber of the cave, and there saw quite a
+complicated apparatus. Part of it was a great steel box, with a lever on
+it.
+
+“We will let you make some diamonds for yourself,” Folwell said to me,
+and he directed me to pull the lever of the box, at a certain signal.
+The signal came, just as a terrific crash of thunder shook the very
+mountain inside of which we were. The box of steel got red-hot, and when
+it cooled off it was opened, and was given a handful of white stones.
+
+“Were they diamonds?” asked Tom, eagerly.
+
+Mr. Jenks held out one hand. In the palm glittered a large
+stone--ostensibly a diamond. In the rays of the moon it showed all the
+colors of the rainbow--a beautiful gem. “That is one of the stones I
+made--or rather that I supposed I had made,” went on Mr. Jenks. “It is
+one of several I have, but they have not all been cut and polished as
+has this one.
+
+“Naturally I was much impressed by what I saw, and, after I had made
+certain tests which convinced me that the stones in the steel box were
+diamonds, I paid over the money as I had promised. That was my undoing.”
+
+“How?”
+
+“As soon as the men got the cash, they had no further use for me. The
+next I remember is eating a rude meal, while we discussed the future of
+making diamonds. I knew nothing more until I found myself back in the
+small hotel at Indian Ridge, whence I had gone some time previous, with
+the men, to the cave in the mountain.”
+
+“What happened?” asked Tom, much surprised by the unexpected outcome of
+the affair.
+
+“I had been tricked, that was all! As soon as the men had my
+money they had no further use for me. They did not want me to learn the
+secret of their diamond making, and they drugged me, carried me away
+from the cave, and left me in the hotel.”
+
+“Didn't you try to find the cave again?”
+
+“I did, but without avail. I spent some time in the Rockies, but no one
+could tell where Phantom Mountain was; in fact, few had heard of it, and
+I was nearly lost searching for it.
+
+“I came back East, determined to get even. I had given the men a
+very large sum of money, and, in exchange, they had given me several
+diamonds. Probably the stones are worth nearly as much as the money I
+invested, but I was cheated, for I was promised an equal share in the
+profits. These were denied me, and I was tricked. I determined to be
+revenged, or at least to discover the secret of making diamonds. It is
+my right.”
+
+“I agree with you,” spoke Tom.
+
+“But, up to the time I met you on Earthquake Island, I could form no
+plan for discovering Phantom Mountain, and learning the secret of the
+diamond makers,” went on Mr. Jenks. “I carried the gems about with me,
+as you doubtless saw when we were on the island. But I knew I needed an
+airship in which to fly over the mountains, and pick out the location of
+the cave where the diamonds are made.”
+
+“But how can you locate it, if you were blindfolded when you were taken
+there, Mr. Jenks?”
+
+“I forgot to tell you that, on our journey into the mountains, and just
+before I was carried into the cave, I managed to raise one corner of
+the bandage. I caught a glimpse of a very peculiarly shaped cliff--it
+is like a great head, standing out in bold relief against the moonlight,
+when I saw it. That head of rock is near the cave. It may be the
+landmark by which we can locate Phantom Mountain.”
+
+“Perhaps,” admitted the young inventor.
+
+“What I want to know is this,” went on Mr. Jenks. “Will you go with me
+on this quest--go in your airship to discover the secret of the diamond
+makers? If you will, I will share with you whatever diamonds we can
+discover, or make; besides paying all expenses. Will you go, Tom Swift?”
+
+The young inventor did not know what to answer. How far was Mr. Jenks
+to be trusted? Were the stones he had real diamonds? Was his story,
+fantastical as it sounded--true? Would it be safe for Tom to go?
+
+The lad asked himself these questions. Mr. Jenks saw his hesitation.
+
+“Here,” said the strange man, “I will prove what I say. Take this
+diamond. I intended it for you, anyhow, for what you did for me on
+Earthquake Island. Take it, and--and give it to the person for whom you
+were about to purchase a diamond to-night. But, first of all, take it to
+a gem expert, and get his opinion. That will prove the truth of what
+I say, Tom Swift, and I feel sure that you will cast your lot in with
+mine, and help me to discover the secret of Phantom Mountain, and aid me
+to get my rights from the diamond makers!”
+
+
+
+
+CHAPTER IV--ANDY FOGER GETS A FRIGHT
+
+
+Tom Swift considered a few minutes. On the face of it, the proposition
+appealed to him. He had been home some time now after his adventures on
+Earthquake Island, and he was beginning to long for more excitement. The
+search for the mysterious mountain, and the cave of the diamond makers,
+might offer a new field for him. But there came to him a certain
+distrust of Mr. Jenks.
+
+“I don't like to doubt your word,” began Tom, slowly, “but you know,
+Mr. Jenks, that some of the greatest chemists have tried in vain to make
+diamonds; or, at best, they have made only tiny ones. To think that any
+man, or set of men, made real diamonds as large as the ones you have,
+doesn't seem--well--” and Tom hesitated.
+
+“You mean you can hardly believe me?” asked Mr. Jenks.
+
+“I guess that's it,” assented Tom.
+
+“I don't blame you a bit!” exclaimed the odd man. “In fact, I didn't
+believe it when they told me they could make diamonds. But they proved
+it to me. I'm ready now to prove it to you.”
+
+“I'll tell you what I'll do. Here's this one stone, cut ready for
+setting. Here's another, uncut,” and Mr. Jenks drew from his pocket
+what looked like a piece of crystal. “Take them to any jeweler,” he
+resumed--“to the one in whose place I saw you to-night. I'll abide by
+the verdict you get, and I'll come here to-morrow night, and hear what
+you have to say.”
+
+“Why do you come at night?” asked Tom, thinking there was something
+suspicious in that.
+
+“Because my life might be in danger if I was seen talking to you, and
+showing you diamonds in the daytime--especially just now.
+
+“Why at this particular time?”
+
+“For the reason that the diamond makers are on my trail. As long as I
+remained quiet, after their shabby treatment of me, and did not try to
+discover their secret, they were all right. But, after I realized that
+I had been cheated out of my rights, and when I began to make an
+investigation, with a view to discovering their secret whereabouts, I
+received mysterious and anonymous warnings to stop.”
+
+“But I did not. I came East, and tried to get help to discover the cave
+of the diamond makers, but I was unsuccessful. I needed an airship, as
+I said, and no person who could operate one, would agree to go with
+me on the quest. Again I received a warning to drop all search for the
+diamond makers, but I persisted, and about a week ago I found I was
+being shadowed.”
+
+“Shadowed; by whom?” asked Tom.
+
+“By a man I never remember seeing, but who, I have no doubt, is one of
+the diamond-making gang.”
+
+“Do you think he means you harm?”
+
+“I'm sure of it. That is the reason I have to act so in secret, and come
+to see you at night. I don't want those scoundrels to find out what I am
+about to do. On my return from Earthquake Island, I again endeavored to
+interest an airship man in my plan, but he evidently thought me insane.
+Then I thought of you, as I had done before, but I was afraid you, too,
+would laugh at my proposition. However, I decided to come here, and I
+did. It seemed almost providential that my first view of you was in
+a jewelry shop, looking at diamonds. I took it as a good omen. Now it
+remains with you. May I call here to-morrow night, and get your answer?”
+
+Tom Swift made up his mind quickly. After all it would be easy enough to
+find out if the diamonds were real. If they were, he could then decide
+whether or not to go with Mr. Jenks on the mysterious quest. So he
+answered:
+
+“I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow
+night. In the meanwhile, for my own satisfaction, I'll let an expert
+look at these stones.”
+
+“Get the greatest diamond expert in the world, and he'll pronounce them
+perfect!” predicted the odd man. “Now I'll bid you goodnight, and be
+going. I'll be here at this time to-morrow.”
+
+As Mr. Jenks turned aside there was a movement among the trees in the
+orchard, and a shadowy figure was seen hurrying away.
+
+“Who's that?” asked the diamond man, in a hoarse whisper. “Did you see
+that, Tom Swift? Some one was here--listening to what I said! Perhaps it
+was the man who has been shadowing me!”
+
+“I think not. I guess it was Eradicate Sampson, a colored man who does
+work for us,” said Tom. “Is that you, Rad?” he called.
+
+“Yais, sah, Massa Tom, heah I is!” answered the voice of the negro,
+but it came from an entirely different direction than that in which the
+shadowy figure had been seen.
+
+“Where are you, Rad?” called the young inventor.
+
+“Right heah,” was the reply, and the colored man came from the direction
+of the stable. “I were jest out seein' if mah mule Boomerang were all
+right. Sometimes he's restless, an' don't sleep laik he oughter.”
+
+“Then that wasn't you over in the orchard?” asked Tom, in some
+uneasiness.
+
+“No, sah, I ain't been in de orchard. I were sleepin' in mah shack, till
+jest a few minutes ago, when I got up, an' went in t' see Boomerang.
+I had a dream dat some coon were tryin t' steal him, an' it sort ob
+'sturbed me, laik.”
+
+“If it wasn't your man, it was some one else,” said Mr. Jenks,
+decidedly.
+
+“We'll have a look!” exclaimed Tom. “Here, Rad, come over and scurry
+among those trees. We just saw some one sneaking around.”
+
+“I'll sure do dat!” cried the colored man. “Mebby it were somebody arter
+Boomerang! I'll find 'em.”
+
+“I don't believe it was any one after the mule,” murmured Mr. Jenks,
+“but it certainly was some one--more likely some one after me.”
+
+The three made a hasty search among the trees, but the intruder had
+vanished, leaving no trace. They went out into the road, which the moon
+threw into bold relief along its white stretch, but there was no figure
+scurrying away.
+
+“Whoever it was, is gone,” spoke Tom. “You can go back to bed, Rad,”
+ for the colored man, of late, had been sleeping in a shack on the Swift
+premises.
+
+“And I guess it's time for me to go, too,” added Mr. Jenks. “I'll be
+here to-morrow night, Tom, and I hope your answer will be favorable.”
+
+Tom did not sleep well the remainder of the night, for his fitful
+slumbers were disturbed by dreams of enormous caves, filled with
+diamonds, with dark, shadowy figures trying to put him into a red-hot
+steel box. Once he awakened with a start, and put his hand under his
+pillow to feel if the two stones Mr. Jenks had given him, were still
+there. They had not been disturbed.
+
+Tom made up his mind to find out if the stones were really diamonds,
+before saying anything to his father about the chance of going to seek
+Phantom Mountain. And the young inventor wished to get the opinion of
+some other jeweler than Mr. Track--at least, at first.
+
+“Though if this one proves to be a good gem, I'll have Mr. Track set it
+in a brooch, and give it to Mary for her birthday,” decided the young
+inventor. “Guess I'll take a run over to Chester in the Butterfly, and
+see what one of the jewelers there has to say.”
+
+In addition to his big airship, Red Cloud, Tom owned a small, swift
+monoplane, which he called Butterfly. This had been damaged by Andy
+Foger just before Tom left on the trip that ended at Earthquake Island,
+but the monoplane had been repaired, and Andy had left town, not having
+returned since.
+
+Telling his father that he was going off on a little business trip,
+which he often did in his aeroplane, Tom, with the aid of Mr. Jackson,
+the engineer, wheeled the Butterfly out of its shed.
+
+Adjusting the mechanism, and seeing that it was in good shape, Tom took
+his place in one of the two seats, for the monoplane would carry two.
+Mr. Jackson then spun the propellers, and, with a crackle and roar the
+motor started. Over the ground ran the dainty, little aeroplane, until,
+having momentum enough, Tom tilted the wing planes and the machine
+sailed up into the air.
+
+Rising about a thousand feet, and circling about several times to test
+the wind currents, Tom headed his craft toward Chester, a city about
+fifty miles from Shopton. In his pocket, snugly tucked away, were the
+two stones Mr. Jenks had given him.
+
+It was not long before Tom saw, looming up in the distance the church
+spires and towering factory chimneys of Chester, for his machine was a
+speedy one, and could make ninety miles an hour when driven. But now a
+slower speed satisfied our hero.
+
+“I'll just drop down outside of the city,” he reasoned, “for too much
+of a crowd gathers when I land in the street. Besides I might frighten
+horses, and then, too, it's hard to get a good start from the street.
+I'll leave it in some barn until I want to go back.”
+
+Tom sent his craft down, in order to pick out a safe place for a
+landing. He was then over the suburbs of the city, and was following the
+line of a straight country road.
+
+“Looks like a good place there,” he murmured. “I'll shut off the motor,
+and vol-plane down.”
+
+Suiting the action to the word, Tom shut off his power. The little craft
+dipped toward the ground, but the lad threw up the forward planes, and
+caught a current of air that sent him skimming along horizontally.
+
+As he got nearer to the ground, he saw the figure of a lad riding a
+bicycle along the country highway. Something about the figure struck Tom
+as being familiar, and he recognized the cyclist a moment later.
+
+“It's Andy Foger!” said Tom, in a whisper. “I wondered where he had been
+keeping himself since he damaged the Butterfly. Evidently he doesn't
+dare venture back to Shopton. Well, here's where I give him a scare.”
+
+Tom's monoplane was making no more noise, now, than a soaring bird. He
+was gliding swiftly toward the earth, and, with the plan in his mind of
+administering some sort of punishment to the bully, he aimed the machine
+directly at him.
+
+Nearer and nearer shot the monoplane, as quietly as a sheet of paper
+might fall. Andy pedaled on, never looking up nor behind him, A moment
+later, as Tom threw up his headplanes, to make his landing more easy,
+and just as he swooped down at one side of the cyclist, our hero let out
+a most alarming yell, right into Andy's ear.
+
+“Now I've got you!” he shouted. “I'll teach you to slash my aeroplane!
+Come with me!”
+
+Andy gave one look at the white bird-like apparatus that had flown up
+beside him so noiselessly, and, being too frightened to recognize Tom's
+voice, must have thought that he had been overtaken by some supernatural
+visitor.
+
+Andy gave a yell like an Indian, about to do a stage scalping act, and
+fairly dived over the handlebars of his bicycle, sprawling in a heap on
+the dusty road.
+
+“I guess that will hold you for a while,” observed Tom, grimly, as he
+put on the ground-brake and brought his monoplane to a stop not far from
+the fallen rider.
+
+
+
+
+CHAPTER V--A MYSTERIOUS MAN
+
+
+For several minutes Andy Foger did not arise. He remained prostrate in
+the dust, and Tom, observing him, thought perhaps the bully might have
+been seriously injured. But, a little later, Andy cautiously raised his
+head, and inquired in a frightened voice:
+
+“Is it--is it gone?”
+
+“Is what gone?” asked Tom, grimly.
+
+At the sound of his voice, Andy looked up. “Was that you, Tom Swift?” he
+demanded. “Did you knock me off my wheel?”
+
+“My monoplane and I together did,” was the reply; “or, rather, we
+didn't. It was the nervous reaction caused by your fright, and
+the knowledge that you had done wrong, that made you jump over the
+handlebars. That's the scientific explanation.”
+
+“You--you did it!” stammered Andy, getting to his feet. He wasn't hurt
+much, Tom thought.
+
+“Have it your own way,” resumed our hero. “Did you think it was a
+hob-goblin in a chariot of fire after you, Andy?”
+
+“Huh! Never mind what I thought! I'll have you arrested for this!”
+
+“Will you? Delighted, as the boys say. Hop in my airship and I'll take
+you right into town. And when I get you there I'll make a charge of
+malicious mischief against you, for breaking the propeller of the
+Butterfly and slashing her wings. I've mended her up, however, so she
+goes better than ever, and I can take you to the police station in jig
+time. Want to come, Andy?”
+
+This was too much for the bully. He knew that Tom would have a clear
+case against him, and he did not dare answer. Instead he shuffled over
+to where his wheel lay, picked it up, and rode slowly off.
+
+“Good riddance,” murmured Tom. He looked about, and saw that he was near
+a house, in the rear of which was a good-sized barn. “Guess I'll ask
+if I can leave the Butterfly there,” he murmured, and, ringing the
+doorbell, he was greeted by a man.
+
+“I'll pay you if you'll let me store my machine in the barn a little
+while, until I go into the city, and return,” spoke the lad.
+
+“Indeed, you're welcome to leave it there without pay,” was the answer.
+“I'm interested in airships, and, I'll consider it a favor if you'll let
+me look yours over while it's here.”
+
+Tom readily agreed, and a few minutes later he had caught a trolley
+going into the city. He was soon in one of the largest jewelry stores of
+Chester.
+
+“I'd like to get an expert opinion as to whether or not those stones are
+diamonds,” spoke Tom, to the polite clerk who came up to wait on him,
+and our hero handed over the two gems which Mr. Jenks had given him.
+“I'm willing to pay for the appraisement, of course,” the young inventor
+added, as he saw the clerk looking rather doubtfully at him, for Tom had
+on a rough suit, which he always donned when he flew in his monoplane.
+
+“I'll turn them over to our Mr. Porter, a gem expert,” said the clerk.
+“Please be seated.”
+
+The young man disappeared into a private office with the stones, and Tom
+waited. He wondered if he was going to have his trouble for his pains.
+Presently two elderly gentlemen came from the little room, on the glass
+door of which appeared the word “Diamonds.”
+
+“Who brought these stones in?” asked one of the men, evidently the
+proprietor, from the deference paid him by the clerk. The latter
+motioned to Tom.
+
+“Will you kindly step inside here?” requested the elderly man. When the
+door was closed, Tom found himself in a room which was mostly taken up
+with a bench for the display of precious stones, a few chairs, and some
+lights arranged peculiarly; while various scales and instruments stood
+on a table.
+
+“You wished an opinion on--on these?” queried the proprietor of the
+place. Tom noticed at once that the word “diamonds” was not used.
+
+“I wanted to find out if they were of any value,” he said. “Are they
+diamonds?”
+
+“Would you mind stating where you got them?” asked the other of the two
+men.
+
+“Is that necessary?” inquired the lad. “I came by them in a legitimate
+manner, if that's what you mean, and I can satisfy you on that point.
+I am willing to pay for any information you may give me as to their
+value.”
+
+“Oh, it isn't that,” the proprietor hastened to assure him. “But these
+are diamonds of such a peculiar kind, so perfect and without a flaw,
+that I wondered from what part of the world they came.”
+
+“Then they are diamonds?” asked Tom, eagerly.
+
+“The finest I have ever tested!” declared the other man, evidently Mr.
+Porter, the gem expert. “They are a joy to look at, Mr. Roberts,” he
+went on, turning to the proprietor. “If it is possible to get a supply
+of them you would be justified in asking half as much again as we charge
+for African or Indian diamonds. The Kimberly products are not to be
+compared to these,” and he looked at the two stones in his hand--the one
+cut, and sparkling brilliantly, the other in a rough state.
+
+“Do you care to state where these diamonds came from?” asked Mr.
+Roberts, looking critically at Tom.
+
+“I had rather not,” answered the lad. “It is enough for me to know that
+they are diamonds. How much is your charge?”
+
+“Nothing,” was the unexpected answer. “We are very glad to have had the
+opportunity of seeing such stones. Is there any chance of getting any
+more?”
+
+“Perhaps,” answered Tom, as he accepted the gems which the expert held
+out to him.
+
+“Then might we speak for a supply?” went on Mr. Roberts, eagerly. “We
+will pay you the full market price.”
+
+“What is the value of these stones?” asked Tom.
+
+Mr. Roberts looked at his gem expert.
+
+“It is difficult to say,” was the answer of the man who had handed Tom
+the gems. “They are so far superior to the usual run of diamonds, that
+I feel justified in saying that the cut one would bring fifteen hundred
+dollars, anywhere. In fact, I would offer that for it. The other is
+larger, though what it would lose in cutting would be hard to say. I
+should say it was worth two thousand dollars as it is now.”
+
+“Thirty-five hundred dollars for these two stones!” exclaimed Tom.
+
+“They are worth every cent of it,” declared Mr. Roberts. “Do you want to
+sell?”
+
+Tom shook his head. He could scarcely believe the good news. Mr. Jenks
+had told the truth. Now the young inventor could go with him to seek the
+diamond makers.
+
+“Can you get any more of these?” went on Mr. Roberts.
+
+“I think so--that is I don't know--I am going to try,” answered the lad.
+
+“Then if you succeed I wish you would sell us some,” fairly begged the
+proprietor of the store.
+
+“I will,” promised Tom, but he little knew what lay before him, or
+perhaps he would not have made that promise. He thanked the diamond
+merchant for his kindness, and arranged to have the cut stone set in a
+pin for Miss Nestor. The uncut gem Tom took away with him.
+
+Thinking of many things, and wondering how best to start in his airship
+Red Cloud for the mysterious Phantom Mountain, Tom hurried back to where
+he had left the monoplane, wheeled it out, and was soon soaring through
+the air toward Shopton.
+
+“I think I'll go with Mr. Jenks,” he decided, as he prepared for a
+landing in the open space near his aeroplane shed. “It will be a
+risky trip, perhaps, but I've taken risks before. When Mr. Jenks comes
+to-night I'll tell him I'll help him to get his rights, and discover the
+secret of the diamond makers.”
+
+As Tom was wheeling the Butterfly into the shed, Eradicate came out to
+help him.
+
+“Dere's a gen'man here to see yo', Massa Tom,” said the colored man.
+
+“Who is it?”
+
+“I dunno. He keep askin' ef yo' de lad what done bust up Earthquake
+Island, an' send lightnin' flashes up to de sky, an' all sech questions
+laik dat.”
+
+“It isn't Mr. Damon; is it, Rad? He hasn't been around in some time.”
+
+“No, Massa Tom, it ain't him. I knows dat blessin' man good an' proper.
+I jest wish he'd bless mah mule Boomerang some day, an' take some oh
+de temper out ob him. No, sah, it ain't Massa Damon. De gen'man's in de
+airship shed waitin' fo' you.”
+
+“In the airship shed! No strangers are allowed in there, Rad.”
+
+“I knows it, Massa Tom, but he done persisted his se'f inter it, an'
+he wouldn't come out when I told him; an' your pa an' Mr. Jackson ain't
+home.”
+
+“I'll see about this,” exclaimed Tom, striding to the large shed, where
+the Red Cloud was kept. As he entered it he saw a man looking over the
+wonderful craft.
+
+“Did you want to see me?” asked Tom, sharply, for he did not like
+strangers prowling around.
+
+“I did, and I apologize for entering here, but I am interested in
+airships, and I thought you might want to hire a pilot. I am in need
+of employment, and I have had considerable to do with balloons and
+aeroplanes, but never with an airship like this, which combines the two
+features. Do you wish to hire any one.”
+
+“No, I don't!” replied Tom, sharply, for he did not like the looks of
+the man.
+
+“I was told that you did,” was the rather surprising answer.
+
+“Who told you?”
+
+The man looked all around the shed, before replying, as if fearful of
+being overheard. Then, stepping close to Tom, he whispered:
+
+“Mr. Jenks told me!”
+
+“Mr. Jenks?” Tom could not conceal his astonishment.
+
+“Yes. Mr. Barcoe Jenks. But I did not come here to merely ask you for
+employment. I would like to hire out to you, but the real object of my
+visit was to say this to you.”
+
+The man approached still closer to Tom, and, in a lower voice, and one
+that could scarcely be heard, he fairly hissed:
+
+“Don't go with Barcoe Jenks to seek the diamond makers!”
+
+Then, before Tom could put out a hand to detain him, had the lad so
+wished, the man turned suddenly, and fairly ran from the shed.
+
+
+
+
+CHAPTER VI--MR. DAMON IS ON HAND
+
+
+The young inventor stood almost spellbound for a few moments. Then
+recovering himself he made a dash for the door through which the
+mysterious man had disappeared. Tom saw him sprinting down the road, and
+was half-minded to take after him, but a cooler thought warned him that
+he had better not.
+
+“He may be one of those men who are on Mr. Jenks' trail,” reasoned Tom,
+in which case it might not be altogether safe to attempt to stop him,
+and make him explain. Or he may be a lunatic, and in that case it
+wouldn't be altogether healthy to interfere with him.
+
+“I'll just let him go, and tell Mr. Jenks about him when he comes
+to-night. But I must warn Rad never to let him in here again. He might
+damage the airship.”
+
+Calling to the colored man, Tom pointed to the stranger, who was almost
+out of sight down the road, and said earnestly:
+
+“Rad, do you see that fellow?”
+
+“I sho do, Massa Tom, but I sorter has t' strain my eyes t' do it. He's
+goin' laik my mule Boomerang does when he's comm' home t' dinnah.”
+
+“That's right, Rad. Well, never let that man set foot inside our fence
+again! If he comes, and I'm home, call me. If I'm away, call dad or Mr.
+Jackson, and if you're here alone, drive him away, somehow.”
+
+“I will, Massa Tom!” exclaimed the colored man, earnestly, “an' if I
+can't do it alone, I'll get Boomerang t' help. Once let dat ar' mule
+git his heels on a pusson, an' dat pusson ain't goin' t' come bodderin'
+around any mo'--that is, not right away.”
+
+“I believe you, Rad. Well, keep a lookout for him, and don't let him
+in,” and with that Tom entered the house to think over matters. They
+were beginning to assume an aspect he did not altogether like. Not that
+Tom was afraid of danger, but he preferred to meet it in the open, and
+the warning, or threat, of the mysterious man disquieted him.
+
+When Mr. Swift came home, a little later, his son told him of the
+midnight interview with Mr. Jenks, for, up to this time, the aged
+inventor was unaware of it, and Tom also gave an account of the
+diamonds, speaking of their value.
+
+“And do you propose to go to Phantom Mountain, in search of the makers
+of these gems, Tom?” asked Mr. Swift.
+
+“I had about decided to do so, dad.”
+
+“And you're going in the Red Cloud?'
+
+“Yes.”
+
+“Who are going with you?”
+
+“Well, Mr. Jenks will go, of course, and I've no doubt but that if I
+mention the prospective trip to Mr. Damon, that he'll bless his skating
+cap, or something like that, and come along.”
+
+“I suppose so, Tom, and I'd like to have you take him. But I think
+you'll need some one else.”
+
+“Because, from what you have told me, you are going out to a dangerous
+part of the country, and you may have to deal with unscrupulous men.
+Three of you are hardly enough to cope with them. You ought to have at
+least another member of your party. If I was not busy on my invention of
+a new wireless motor I would go along, but I can't leave. You might take
+Mr. Jackson.”
+
+“No, you need him here to help you, dad.”
+
+“How about Eradicate?”
+
+Tom smiled.
+
+“Rad would get homesick for his mule Boomerang, and I'd have to bring
+him back just when we'd found the diamonds,” replied the young inventor.
+“No, we'll have to think of some one else. I'll ask Mr. Damon, and then
+I'll consider matters further. I expect to see Mr. Jenks to-night, and
+he may have some one in mind.”
+
+“Perhaps that will be a good plan. Well, Tom, I trust you will take good
+care of yourself, and not run into unnecessary danger. Is the Red Cloud
+in good shape for the voyage?”
+
+“It needs looking over. I'm going to get right at it.”
+
+“It's a pretty indefinite sort of a quest you're going on, Tom, my son.
+How do you expect to find Phantom Mountain?”
+
+“Well, it's going to be quite a task. In the first place we'll head for
+Leadville, Colorado, and then we'll go to Indian Ridge and make some
+inquiries. We may get on the track of the place that way. If we don't,
+why I'll take the airship up as high as is necessary and sort of
+prospect until we see that big cliff that's shaped like a head. That
+will give us something to go by.”
+
+“Well, do the best you can. If you can discover the secret of making
+diamonds it will be a valuable one.”
+
+“I guess it will, dad; and Mr. Jenks is entitled to know it, for he paid
+his good money to that end. He has promised to go halves with me, as
+payment for the use of the airship, and I must say the two diamonds he
+gave me last night have proved very valuable.”
+
+“Two diamonds, Tom? You only showed me one, an uncut gem;” and Mr. Swift
+looked at his son.
+
+“Oh, the other--er--the other is--I left it with a jeweler,” and Tom
+blushed a trifle, as he thought of the present he contemplated making to
+Mary Nestor.
+
+That afternoon, as Tom was out in the shed of the Red Cloud looking over
+the airship, to see what would be necessary to do to it in order to get
+it in shape for a long trip, he heard voices outside.
+
+“Yes--yes, I know the way in perfectly well,” he caught. “You needn't
+bother to come, my good fellow. Just step this way, and I'll show you
+something worth seeing.”
+
+“I wonder if it's that mysterious man coming back?” thought Tom. He
+dropped the tool he was using, and hurried to the door. As he approached
+it he heard the voice continue.
+
+“Why bless my shoe laces, Mr. Parker! You'll see a wonderful airship, I
+promise you. Wonderful! Bless my hatband, but I hope Tom is here!”
+
+“Mr. Damon!” exclaimed our hero, as he recognized the tones of his
+eccentric friend. “But who is with him?”
+
+A moment later he caught sight of the gentleman who was always blessing
+himself, or something. Behind him stood another man, whose features Tom
+could not see plainly.
+
+“Hello, Tom Swift!” called Mr. Damon. “Looking over the Red Cloud, eh?
+Does that mean you're off on another trip?”
+
+“I guess it does,” answered the lad.
+
+“Where to this time? if I may ask.”
+
+“I'm thinking of going off to the mountains to find a band of men
+engaged in making diamonds,” replied Tom.
+
+“Making diamonds! Bless my finger ring! Making diamonds! A trip to the
+mountains! Bless my disposition! but do you know I'd like to go with
+you!”
+
+“I was thinking of asking you, Mr. Damon.”
+
+“Were you? Bless my heart, I'm glad you thought of me. You don't by any
+possible chance want another person; do you?”
+
+“We were thinking of having four in the party, Mr. Damon,” and Tom
+wondered who was with his eccentric friend.
+
+“Then bless my election ticket! This is the very chance for you, Mr.
+Parker!” cried Mr. Damon. “Will you go with us? It will be just what you
+need,” and Mr. Damon stepped aside, revealing to Tom the features of Mr.
+Ralph Parker, the scientist who had correctly predicted the destruction
+of Earthquake Island.
+
+
+
+
+CHAPTER VII--MR. PARKER PREDICTS
+
+
+Tom Swift was a most generous lad, but when he saw that Mr. Damon had
+with him Mr. Parker, the gloomy scientist, who seemed to take delight in
+predicting disasters, our hero's spirits were not exactly of the best.
+He would have much preferred not to take Mr. Parker on the quest for the
+diamond makers, but, since Mr. Damon had mentioned it, he did not see
+how he could very well refuse.
+
+“But perhaps he won't care to go,” thought Tom.
+
+He was undeceived a moment later, however, for the scientist remarked:
+
+I am very glad to meet you once more, Mr. Swift. I have scarcely thanked
+you enough for what you did for us in erecting your wireless station on
+Earthquake Island, which, as you recall, I predicted would sink into
+the sea. It did, I am glad to say, not because I like to see islands
+destroyed, but because science has been vindicated. Now I have just
+heard you remark that you are about to set off to the mountains in
+search of some men who are making diamonds. I need hardly state that
+this is utterly useless, for no diamonds, commercially valuable, can be
+made by men. But the trip may be valuable in that it will permit me to
+demonstrate some scientific facts.
+
+“Therefore, if you will permit me, I will be very glad to accompany you
+and Mr. Damon. I shall be delighted, in short, and I can start as soon
+as you are ready.”
+
+“There's no hope for it!” thought Tom, dismally. “I suppose he'll wake
+up every morning, and predict that before night the world will come to
+an end, or he'll prophesy that the airship will blow up, and vanish,
+when about seven miles above the clouds. Well, there's no way out of it,
+so here goes.”
+
+Thereupon Tom welcomed the scientist as cordially as he could, and
+invited him to form one of the party that would set off in the airship
+to search for Phantom Mountain.
+
+“Bless my jewelry box!” exclaimed Mr. Damon, when this formality was
+over. “Tell me more about it, Tom.”
+
+Which our hero did, stating the need of maintaining secrecy on account
+of the danger to Mr. Jenks. Mr. Damon and Mr. Parker both agreed to say
+nothing about the matter, and then the scientist became much interested
+in the Red Cloud, which he closely examined. He even complimented Tom on
+the skill shown in making it, and, contrary to our hero's expectation,
+did not predict that it would blow up the next time it was used.
+
+“How did you happen to arrive just at this time, Mr. Damon?” asked Tom.
+
+“It was partly due to Mr. Parker,” was the answer. “I had not seen him
+since we were rescued from the island, until a few days ago he called
+on me at my home. I happened to mention that you lived near here, and
+suggested that he might like to see some of your inventions. He agreed,
+and we came over in my auto. And now, bless my liver-pin! I find you
+about to start off on another trip.”
+
+“And have you fully decided to go with me?” asked Tom. “There may be
+danger, and I don't like the way that mysterious man behaved.”
+
+“Oh, bless my revolver!” cried Mr. Damon. “I'm used to danger by this
+time. Of course I'm going, and so is Mr. Parker. Do you know,” and the
+man, who was always blessing something, came closer to the lad, and
+whispered: “Do you know, Tom, Mr. Parker is a very peculiar individual.”
+
+“I'm sure of it,” answered the young inventor, looking at the gentleman
+in question, who was then inside the airship cabin.
+
+“But he's all right, even if he is predicting unpleasant things,” went
+on Mr. Damon. “I think we'll get better acquainted with him after a
+bit.”
+
+“I hope so,” agreed Tom, but he did not realize then how close his
+companionship with Mr. Parker was to be, nor what dangers they were to
+share later.
+
+The friends talked at considerable length of the prospective trip, and
+Tom, by this time, had ascertained what needed to be done to the airship
+to get it in shape to travel. It would take about a week, and, in the
+meanwhile, Mr. Damon would go home and get his affairs in order for
+the voyage. Tom's father was introduced to Mr. Parker, and, the former,
+finding that the scientist held some views in common with him, invited
+the gloomy predictor to remain at the Swift home until the Red Cloud was
+ready to sail. Tom could not repress a groan at this, but he decided he
+would have to make the best of it.
+
+Mr. Damon left for home that afternoon, promising to be on hand at the
+time set to start for Phantom Mountain.
+
+Tom was up waiting for Mr. Jenks at twelve o'clock that night. Shortly
+after the hour he saw a dark figure steal into the orchard. At first he
+feared lest it might be one of the spies who were, he was now convinced,
+on the trail of the man who was seeking to discover the secret of the
+diamond makers. But a whistle, which came to the lad's ear a moment
+later (that being a signal Mr. Jenks had agreed to sound), told Tom that
+it was none other than the visitor he expected.
+
+“All right, Mr. Jenks, I'm here,” called Tom, cautiously. “Come over
+this way,” and he went out from the shadow of the house, where he had
+been waiting, and met the men. “We'll go into my private work-shop,” the
+youth added, leading the way.
+
+“Have you decided to go with me?” asked Mr. Jenks, in an anxious
+whisper. “Did you find the diamonds to be real ones?”
+
+“I did; and I'm going,” spoke Tom.
+
+“Good! That relieves my mind. But we are still in danger. I was followed
+by my shadower to-day, and only succeeded in shaking him off just before
+coming here. I don't believe he knows what I am about to do.”
+
+“Oh, yes he does,” said Tom.
+
+“He does? How?”
+
+“Because he was here, and warned me against you!”
+
+“You don't mean it! Well, they are getting desperate! We must be on our
+guard. What sort of a man was he?”
+
+Tom described the fellow, and Mr. Jenks stated that this tallied with
+the appearance of the person who had been shadowing him.
+
+“But we'll fool them yet!” cried Tom, who had now fully entered into the
+spirit of the affair. “If they can follow us in the Red Cloud they're
+welcome to. I think we'll get ahead of them.”
+
+He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed that
+it would add to the strength of the party to take these two gentlemen
+along.
+
+“Though I can't say I care so much for Mr. Parker,” he added. “But now
+as to ways and means. When can we start?”
+
+Thereupon he and Tom talked over details in the seclusion of the little
+office, and arranged to leave Shopton in about a week. In the meanwhile
+the airship would be overhauled, stocked with supplies and provisions,
+and be made ready for a swift dash to the mountains.
+
+“And now I must be going,” said Mr. Jenks. “I have a great deal to do
+before I can start on this trip, and I hope I am not prevented by any of
+those men who seem to be trailing me.”
+
+“How could they prevent you?” Tom wanted to know.
+
+“Oh, there are any number of ways,” was the answer. “But I'm glad you
+found that my diamonds were real. We'll soon have plenty, if all goes
+well.”
+
+As Mr. Jenks left the shop, he started back, in some alarm.
+
+“What's the matter?” asked Tom.
+
+“Over there--I thought I saw a figure sneaking along under the
+trees--that man--perhaps--”
+
+“That's Eradicate, our colored helper,” replied Tom, with a laugh.
+“I posted him there to see that no strangers came into the orchard.
+Everything all right, Rad?” he asked, raising his voice.
+
+“Yais, sah, Massa Tom. Nobody been around yeah this night.”
+
+“That's good. You can go to bed now,” and Eradicate, yawning loudly,
+went to his shack. A little later Tom sought his own room, Mr. Jenks
+having hurried off to town, where he was boarding.
+
+The next few days saw Tom busily engaged on the airship, making some
+changes and a few repairs that were needed. His father, Eradicate and
+Mr. Jackson helped him. As for Mr. Parker, the scientist, he went about
+the place, being much interested in the various machines which Tom or
+Mr. Swift had patented.
+
+At other times the scientist would stroll about the extensive grounds,
+making what he said were “observations.” One afternoon Tom saw him,
+apparently much excited, kneeling down back of a shed, with his ear to
+the ground.
+
+“What is the matter?” asked the lad, thinking perhaps Mr. Parker might
+be ill.
+
+“Have you ever had any earthquakes here, Tom Swift?” asked the
+scientist, quietly.
+
+“Earthquakes? No. We had enough of them on the island.”
+
+“And you are going to have one here, in about two minutes!” cried Mr.
+Parker. “I predict that this place will be shaken by a tremendous shock
+very soon. We had all better get away from the vicinity of buildings.”
+
+“What makes you think there will be an earthquake?” asked Tom.
+
+“Because I can hear the rumbling beneath the ground at this very minute.
+It is increasing in volume, showing that the tremors are working this
+way. There will soon be a great subterranean upheaval! Listen for
+yourself.”
+
+Tom cast himself down on the grass. Placing his ear close to the ground
+he did hear a series of dull thuds. He arose, not a little alarmed.
+There had never been any earthquakes in Shopton, yet he had great
+respect for Mr. Parker's scientific attainments.
+
+Just then Eradicate Sampson came along. He saw Tom and Mr. Parker lying
+flat on the ground, and surprise showed on his honest, black face.
+
+“Fo' de land sakes!” cried Eradicate. “What am de mattah now, Massa
+Tom?”
+
+“Earthquake coming,” answered Tom, briefly. “Better get away from the
+buildings, Rad. They might fall!” Tom's face showed the alarm he felt.
+What would happen to all of his valuable machines--to the Red Cloud?
+
+“Earthquake?” murmured Eradicate, and he, too, cast himself down to
+listen. A moment later he arose with a laugh.
+
+“What's the matter?” cried Tom.
+
+“Why, dat ain't no earthquake!” declared the colored man.
+
+“No. Then perhaps you know what it is,” said Mr. Parker, somewhat
+sharply.
+
+“Course I knows what it am,” answered Eradicate, with dignity. “Dat
+noise am my mule Boomerang, kickin' in his stable, on account oh me not
+feedin' him yet. Dat's what it am. I'se gwine right now t' gib him his
+oats, and den yo' see dat de noise stop. Boomerang allers kick dat way
+when he's hungry. I show yo'!”
+
+And, sure enough, when Eradicate had gone to the mule's stable,
+which was near where Mr. Parker had heard the mysterious sounds, they
+immediately ceased.
+
+“Dat mule was all de earthquake dere was around here,” said the colored
+man as he came out.
+
+Mr. Parker walked away, saying nothing, and Tom did not make any
+comments--just then.
+
+
+
+
+CHAPTER VIII--OFF FOR THE WEST
+
+
+It was a great relief to Tom, to find that there was no danger from an
+earth tremor. Now that he had made up his mind to go in search of
+the diamond makers, he wanted nothing to interfere with it. Lest the
+feelings of Mr. Parker might be hurt by the mistake he had made, the
+young inventor cautioned Eradicate not to say anything more about the
+matter.
+
+“'Deed an' I won't,” the colored man promised. “I'se only too glad dere
+wa'n't no earthquake, dat's what I is.”
+
+As for Mr. Parker, he did not appear much put out by his error in
+predicting.
+
+“I am sure that what I heard was a tremor, due to some distant
+earthquake shock,” he said. “The mule's kicking was only a coincidence.”
+
+And Tom let him have his way about it. The week was drawing to a close,
+and the Red Cloud was nearly in shape for the voyage. At almost the
+last minute Tom found that he needed some electrical apparatus for the
+airship, and as he had to go to Chester for it, he decided he would make
+the trip in his monoplane, and, while in the city, would also get the
+diamond pin he was having made for Mary Nestor.
+
+He started off early one morning, in the swift little craft Butterfly,
+and soon had reached Chester. The diamond brooch was ready for him.
+
+“It is one of the most beautiful stones we have ever set,” the diamond
+merchant told him. “Don't forget, if you find any more, Mr. Swift, to
+let us have a chance to bid on them.”
+
+“I may,” Tom promised, rather indefinitely. Then, having purchased his
+electrical supplies, he made a quick trip to Shopton, stopping on the
+way to call on Miss Nestor.
+
+“Why Tom, I'm delighted to see you!” cried the girl, blushing prettily.
+“Did you come for some apple turnovers?” and she laughed, as she
+referred to a call Tom had once paid, when a new cook had been engaged,
+and when the pastry formed a feature of the meal.
+
+“No turnovers this time,” said the young inventor. “I came to wish you
+many happy returns of the day.”
+
+“Oh, you remembered my birthday! How nice of you!”
+
+“And here is something else,” added our hero, rather awkwardly, as he
+handed her the diamond pin.
+
+“Oh, Tom! This for me! Oh, it's too lovely--it's far too much!”
+
+“It isn't half enough!” he declared, warmly.
+
+“Oh, what a large diamond!” Mary cried as she saw the sparkling stone.
+“I never saw one so large and beautiful!”
+
+“It's just as easy to make them large as small,” explained Tom.
+
+“Make them?” she looked the surprise she felt.
+
+“Yes, I'm about to start for the place where diamonds are made.”
+
+“Oh, Tom! But isn't it dangerous? I mean won't you have to go to some
+far country--like Africa--to get to where diamonds are made?”
+
+“Well, we are going on quite a trip, but not as far as that. And as
+for the danger--well, we'll have to take what comes,” and he told her
+something of the proposed quest.
+
+“Oh, it sounds--sounds scary!” Mary exclaimed, when she had heard of Mr.
+Jenks' experience. “Do be careful, Tom!”
+
+“I will,” he promised, and, somehow he was glad that she had cautioned
+him thus--and in such tones as she had used. For Mary Nestor was a girl
+that any young chap would have been glad to have manifest an interest in
+him.
+
+“Well, I guess I'll have to say good-by,” spoke Tom, at length. “We
+expect to start in a couple of days, and I may not get another chance to
+see you.”
+
+“Oh, I--I hope you come back safely,” faltered Mary, and then she held
+out her hand, and Tom--well, it's none of our affair what Tom did
+after that, except to say that he hurried out, fairly jumped into his
+monoplane, and completed the trip home.
+
+As the Red Cloud has been fully described in the volume entitled “Tom
+Swift and His Airship,” we will not go into details about it now.
+Sufficient to say that it was a combination of a biplane and dirigible
+balloon. It could be used either as one or the other, and the gas-bag
+feature was of value when the wind was too great to allow the use of the
+planes, or when the motive power, for some reason stopped. In that event
+the airship could remain suspended far above the clouds if necessary.
+There was provision for manufacturing the gas on board.
+
+The Red Cloud was fitted up to accommodate about ten persons, though it
+was seldom that this number was carried. Two persons could successfully
+operate the machinery. There were sleeping berths, and in the main cabin
+a sitting-room, a dining-room, and a kitchen. There was also the motor
+compartment, and a steering tower, from which the engines could be
+controlled.
+
+It was in this craft that the seekers after the diamond makers proposed
+undertaking the trip. Mr. Damon came on from his home in Waterfield
+about two days before the date set to leave, and Mr. Jenks, had, three
+days before this, taken up his abode at the Swift home. Mr. Parker, as
+has been stated, was already there, and he had put in his time making
+a number of scientific observations, though he had made no more
+predictions.
+
+Nothing more had been seen of the mysterious man who had warned Tom,
+and the young inventor and Mr. Jenks began to hope that they had thrown
+their enemies off the track.
+
+“Though I don't imagine they'll give up altogether,” said Mr. Jenks.
+“They're too desperate for that. We'll have trouble with them yet.”
+
+“Well, it can't be helped,” decided Tom. “We'll try and be ready for it,
+when it comes,” and then, dismissing the matter from his mind, he busied
+himself about the airship.
+
+The food and supplies had all been put aboard, and they expected to
+start the next morning. In order to make sure that any stones which they
+might succeed in getting from the diamond makers were real gems, a set
+of testing apparatus was taken along. Mr. Parker had had some experience
+in this line, and, in spite of the fact that he might make direful
+predictions, Tom was rather glad, after all, that the scientist was
+going to accompany them.
+
+“But what is worrying me,” said Mr. Damon, “is what we are going to do
+after we get to Phantom Mountain. What are your plans, Mr. Jenks? Will
+you go in, and demand your share of the diamond-making business?”
+
+“I have a right to it, as I invested a large sum in it, and I am
+entitled to more than a half-share. But, of course, I can't say what
+I'll do until I get there. We may have to act very secretly.”
+
+“I'm inclined to think we will,” said Tom. “My plan would be to gain
+access to the cave, if possible, and watch them at work. We might be
+able to discover the secret of making diamonds, and, after all, that's
+what you want, isn't it, Mr. Jenks?”
+
+“Yes, I paid my money for the secret, and I ought to have it. If I can
+get it quietly, so much the better. If not, I'll fight for my rights!”
+ and he looked very determined.
+
+“Bless my powder horn!” cried Mr. Damon. “That's the way to talk! And
+so we're to go cruising about in the air, looking for a mountain shaped
+like a man's head.”
+
+“That's it,” agreed Mr. Jenks, “and when we find it we will be near
+Phantom Mountain, and the diamond makers.”
+
+The final details were completed that night. The last of the supplies
+had been put aboard, the larder was well stocked, the diamond testing
+apparatus was stored safely away, and all that remained was for the
+adventurers to board the Red Cloud in the morning, and soar away.
+
+That night Tom was uneasy. Several times he got up, and looked toward
+the shed where the airship was stored. He could not rid himself of
+the idea that the men to whose interest it was that the diamond-making
+secret remain undiscovered, might attempt to wreck the airship before
+the start. Consequently both Eradicate Sampson and Engineer Jackson were
+on guard. Tom looked from his window, to the shed where the Red Cloud
+was housed. He saw nothing to cause him any uneasiness.
+
+“I guess I'm just nervous,” he mused. “But, all the same, I'll be glad
+when we've started.”
+
+They were all up early the next morning, Mr. Damon beginning the day by
+blessing the sunrise, and many other things that struck his fancy.
+The airship was wheeled out of the shed, and Tom gave her a final
+inspection.
+
+“It's all right,” he declared. “All aboard!”
+
+“Now, do be careful,” begged Mr. Swift. “Don't take too many chances,
+Tom.”
+
+“I'll not.”
+
+The adventurers were in the forward part of the ship, and Tom had taken
+his place at the wheels and levers in the pilot house. As he was about
+to start the motor he looked toward the road, and saw a horse and
+carriage. In the vehicle was a girlish figure, at the sight of which Tom
+blushed and smiled. He waved his hand.
+
+“I came to wish you good luck!” cried Mary Nestor, for it was she in the
+carriage.
+
+“Thanks!” cried Tom, leaning from the window of the pilot house. “It was
+good of you to get up so early.”
+
+“Oh. I'm always up early,” she informed him.
+
+“Look out that the motor doesn't scare your horse,” Tom warned her.
+
+“Old Dobbin doesn't mind anything,” was her answer. “I'll see that he
+doesn't run away with me, as long as you're not on earth to rescue me.
+Good-by, Tom!”
+
+“Good-by!” he called, and then he pulled the lever that set in motion
+the motor, and whirled the great propellers about. They whizzed around
+with a roar, and the Red Cloud, shivering and trembling with the
+vibration, rose in the air like some great bird.
+
+“We're off for the West and Phantom Mountain!” called Tom to his
+companions.
+
+As the airship soared upward, Eradicate Sampson ran forward from where
+he had been standing near his mule Boomerang. He waved his hands, and
+shouted something.
+
+“Bless my hatband! What does he want?” asked Mr. Damon, watching him
+curiously.
+
+“It sounds as if he were calling to us to come back,” spoke Mr. Parker.
+
+“It's too late now,” decided Tom. “Maybe he forgot to tell us good-by,”
+ but, he felt a vague wonder at Eradicate's odd motions; for the colored
+man was pointing toward the stern of the airship, as if there was
+something wrong there. But the Red Cloud soared on.
+
+
+
+
+CHAPTER IX--A WARNING BY WIRELESS
+
+
+Rapidly the airship ascended, and, when it was high over the town of
+Shopton, Tom headed the craft due west. Looking down he tried to descry
+Mary Nestor, in her carriage, but the trees were in the way, their
+interlocking branches hiding the girl. Tom did see crowds of other
+persons, though, thronging the streets of Shopton, for, though the young
+inventor had made many flights, there was always a novelty about them,
+that brought out the curious.
+
+“A good start, Tom Swift,” complimented Mr. Parker. “Is it always as
+easy as this?”
+
+“Starting always is,” was the answer, “though, as the Irishman said,
+coming down isn't sometimes quite so comfortable.”
+
+“Bless my gizzard! That's so,” cried the eccentric Mr. Damon. “Can we
+vol-plane to earth in the Red Cloud, Tom?”
+
+“Yes, but not as easily as in the Butterfly. However I hope we will not
+have to. Now, Mr. Damon, if you will just take charge of the steering
+apparatus for a minute, I want to go aft.”
+
+“What for?”
+
+“I wish to see if everything is all right. I can't imagine why Eradicate
+was making those queer motions.”
+
+Mr. Damon, who knew how to operate the Red Cloud, was soon guiding her
+on the course, while Tom made his way to the rear compartments, through
+the motor room, where the stores of supplies and food were kept. He made
+a careful examination, looking from an after window, and even going out
+on a small, open platform, but could discover nothing wrong.
+
+“I guess Rad was just capering about without any special object,” mused
+Tom, but it was not long after this that they learned to their dismay,
+that the colored man had had a method in his madness.
+
+On his way back through the motor room Tom looked to the machinery,
+and adjusted some of the auxiliary oil feeders. The various pieces of
+apparatus were working well, though the engine had not yet been speeded
+up to its limit. Tom wanted it to “warm-up” first.
+
+“Everything all right?” asked Mr. Damon, as Tom rejoined them in the
+pilot house, which was just forward of the living room in the main
+cabin.
+
+“Yes, I can't imagine what made Rad act that way. But I'll set the
+automatic steering gear now, Mr. Damon, and then you will be relieved.”
+
+Mr. Jenks was gazing off toward the west--to where he hoped to discover
+the secret of Phantom Mountain.
+
+“How do you like it?” asked Tom.
+
+“It's great,” replied the diamond man. “I've never been in an airship
+before, and it's different than what I expected; but it's great! It's
+the only craft that will serve our purpose among the towering mountain
+peaks, where the diamond makers are hidden. I hope we can find them.”
+
+In a little while the Red Cloud was skimming along at faster speed,
+guided by the automatic rudders, so that no one was needed in the pilot
+house, since there was no danger of collisions. Airships are not quite
+numerous enough for that, yet, though they may soon become so.
+
+Tom and the others devoted several hours to arranging their staterooms
+and bunks, and getting their clothing stowed away, and when this was
+done Mr. Parker and Mr. Jenks sat gazing off into space.
+
+“It's hard to realize that we are really in an airship,” observed the
+diamond man. “At first I thought I would be frightened, but I'm not a
+bit. It doesn't seem as if anything could happen.”
+
+“Something is likely to happen soon,” said Mr. Parker, suddenly, as he
+gazed at some weather instruments on the cabin wall.
+
+“Bless my soul! Don't say that!” cried Mr. Damon. “What is it?”
+
+“I think, from my observations, that we will soon have a hurricane,”
+ said the scientific man. “There is every indication of it;” and he
+seemed quite delighted at the prospect of his prediction coming true.
+
+“A hurricane!” cried Mr. Damon. “I hope it isn't like the one that blew
+us to Earthquake Island.”
+
+“Oh, I think there will be no danger,” spoke Tom. “If it comes on to
+blow we will ascend or descend out of the path of the storm. This craft
+is not like the ill-fated Whizzer. I can more easily handle the Red
+Cloud; even in a bad storm.”
+
+“I'm glad to hear that,” remarked Mr. Jenks. “It would be too bad to be
+wrecked before we got to Phantom Mountain.”
+
+“Well, I predict that we will have a bad storm,” insisted Mr. Parker,
+and Tom could not help wishing that the scientist would keep his gloomy
+forebodings to himself.
+
+However the storm had not developed up to noon, when Tom, with Mr.
+Damon's help, served a fine meal in the dining-room. In the afternoon
+the speed of the ship was increased, and by night they had covered
+several hundred miles. Through the darkness the Red Cloud kept on,
+making good time. Tom got up, occasionally, to look to the machinery,
+but it was all automatically controlled, and an alarm bell would sound
+in his stateroom when anything went wrong.
+
+“Bless my napkin!” exclaimed Mr. Damon the next morning, as they sat
+down to a breakfast of fruit, ham and eggs and fragrant coffee, “this is
+living as well as in a hotel, and yet we are--how far are we above the
+earth, Tom?” he asked, turning to the young inventor.
+
+“About two miles now. I just sent her up, as I thought I detected that
+storm Mr. Parker spoke of.”
+
+“I told you it would come,” declared the scientist, and there was a
+small hurricane below them that morning, but only the lower edge of it
+caught the Red Cloud, and when Tom sent her up still higher she found a
+comparatively quiet zone, where she slid along at good speed.
+
+That afternoon Tom busied himself about some wires and a number of
+complicated pieces of apparatus which were in one corner of the main
+cabin.
+
+“What are you doing now?” asked Mr. Jenks, who had been talking with Mr.
+Parker, and showing that scientist some of the manufactured diamonds.
+
+“Getting our wireless apparatus in shape,” answered the lad. “I should
+have done it before, but I had so much to do that I couldn't get at it.
+I'm going to send off some messages. Dad will want to know how we are
+doing.”
+
+As he worked away, he also made up his mind to send another message, in
+care of his father, for there was a receiving station in the Swift home.
+And to whom this message was addressed Tom did not say, but we fancy
+some of our readers can guess.
+
+Finally, after several hours of work, the wireless was in shape to send
+and receive messages. Tom pulled over the lever, and a crackling sound
+was heard, as the electricity leaped from the transmitters into space.
+Then he clamped the receiver on his ear.
+
+“All ready,” he announced. “Has anybody any messages they wish sent?”
+ For, with the courtesy of a true host he was ready to serve his guests
+before he forwarded his own wireless notes.
+
+“Just tell my wife that I'm enjoying myself,” requested Mr. Damon.
+“Bless my footstool! But this is great! We're off the earth yet,
+connected with it.”
+
+Mr. Jenks had no one to whom he wanted to send any word, but Mr. Parker
+wish to wire to a fellow scientist the result of some observations made
+in the upper air.
+
+Tom noted all the messages down, and then, when all was in readiness he
+began to call his home station. He knew that either his father or Mr.
+Jackson, the engineer, could receive the wireless.
+
+But, no sooner had the young inventor sent off the first few dots and
+dashes representing “S. I.”--his home station call--than he started and
+a look of surprise came over his face.
+
+“They're calling us!” he exclaimed.
+
+“Who is?” asked Mr. Jenks.
+
+“My house--my father. He--he's been trying to get us ever since we
+started, but I didn't have the wireless in shape to receive messages.
+Oh, I hope it's not too late!”
+
+“Too late! Bless my soul, too late for what?” gasped Mr. Damon, somewhat
+alarmed by Tom's manner.
+
+The lad did not answer at once. He was intently listening to a series
+of dots and dashes that clicked in the telephone receiver clamped to his
+left ear. On his face there was a look of worriment.
+
+“Father has just sent me a message,” he said. “It's a warning flashed
+through space! He's been trying to get it to me since yesterday!”
+
+“What is it?” asked Mr. Jenks, rising from his seat.
+
+“The mysterious man is aboard the airship--hidden away!” cried Tom.
+“That's what Eradicate was trying to call to our attention as we started
+off. Eradicate saw his face at a rear window, and tried to warn us! The
+mysterious man is a stowaway on board!”
+
+
+
+
+CHAPTER X--DROPPING THE STOWAWAY
+
+
+Tom's excited announcement startled Mr. Damon and the others as much as
+if the young inventor had informed them that the airship had exploded
+and was about to dash with them to the earth. The men leaped to their
+feet, and stared at the lad.
+
+“A stowaway on board!” cried Mr. Damon. “Bless my soul! How did he--”
+
+“Are you sure that message is straight?” asked Mr. Jenks. “Did Eradicate
+see the man?”
+
+“He says he did,” answered Tom. “The man is hidden away on board
+now--probably among the stores and supplies.”
+
+“Bless my tomato sauce!” exploded Mr. Damon. “I hope he doesn't eat them
+all up!”
+
+“We must get him out at once!” declared Mr. Jenks.
+
+“I knew something would happen on this voyage,” came from Mr. Parker. “I
+predicted it from the first!”
+
+Tom thought considerable, but he did not answer the scientist just
+then. Another communication was coming to him by wireless. He listened
+intently.
+
+“Father says,” the lad told his companions “that Eradicate only had
+a glimpse of the man at the last moment. He was looking from the rear
+storeroom window--he's the same man who called on me that time--Rad
+remembers him very well.”
+
+“Bless my shoes! What's to be done?” inquired Mr. Damon, looking around
+helplessly.
+
+“We must get him out, that's all,” decided Mr. Jenks; with vigor. “Get
+him out and drop him overboard!”
+
+“Drop him overboard!” cried Mr. Parker, in horror.
+
+“Not exactly, but get rid of him,” proceeded the diamond seeker. “That
+man is one of my enemies. He has been sent by the band of diamond makers
+hidden among the mountains, to spy on me, and, if possible, prevent me
+from seeking to discover their secret. He tried to work on Tom's Swift's
+fears, and frighten him from using his airship on this quest. Then, when
+he failed, the man must have sneaked into the shed, and hidden himself
+in the ship. We must get rid of him, or he may wreck the Red Cloud!”
+
+“That's so!” cried Tom. “We must try to capture him. I think we had
+better--” the lad paused, and again listened to the wireless message.
+“Father says Eradicate saw the man have a gun, so we must be careful,”
+ the young inventor translated the dots and dashes.
+
+“Bless my powder horn!” exploded Mr. Damon.
+
+“We shall have to proceed cautiously then,” spoke Mr. Jenks. “If he is
+like any others in the gang he is a desperate man.”
+
+“Better sneak up on him then, if we can,” proposed Mr. Parker. “There
+are enough of us to cope with one man, even if he is armed. You have
+weapons aboard, haven't you?” he inquired of Tom.
+
+“Yes,” was the hesitating answer, “but I don't want to use them if I
+can help it. Not only because of the danger, and a dislike of shedding
+blood, but because a stray bullet might pierce the gas bag and damage
+the ship.”
+
+“That's so,” agreed Mr. Jenks. “Well, I guess if we go at it the right
+way we can capture him without any shooting. But we must talk more
+quietly--we ought to have whispered--he may have heard us.”
+
+“I don't think so,” replied Tom. “The storeroom is far enough off so
+that he couldn't hear us. Besides, the motor makes such a racket that
+he couldn't distinguish what we were talking about, even if he heard our
+voices. So, unless he heard the wireless working, and suspects something
+from that, he probably doesn't know that we are aware of his presence
+aboard.”
+
+“But why do you think he has remained quiet all this while, Tom?” asked
+Mr. Damon.
+
+“Probably he wants to wait until the ship is farther out west,”
+ suggested Mr. Jenks. “Then he will be nearer his friends, and can get
+help, if he needs it.”
+
+“And do you really believe he would destroy the Red Cloud?” asked Mr.
+Parker.
+
+“I think that all he is waiting for is a favorable chance,” declared
+the diamond seeker. “He would destroy the craft, and us too, if he could
+prevent us from discovering the secret of Phantom Mountain, I believe.”
+
+“Then we must get ahead of him,” decided Tom, quietly. “I have just
+flashed to dad a message, telling him that we will heed his warning. Now
+to capture the stowaway!”
+
+“And while we're about it, give him a good scare when we do get him,”
+ suggested Mr. Jenks.
+
+“How?” asked Tom.
+
+“Threaten to drop him overboard. Perhaps that will make him tell how
+he happened to get in our ship, and what are the plans of the gang of
+diamond makers. We may get valuable information that way.”
+
+“I don't believe you can scare such fellows much,” was Tom's opinion,
+but it was agreed to try.
+
+“How are you going to capture him?” asked Mr. Parker. “If he has a gun
+it won't be any too easy to go in the storeroom, and drag him out.”
+
+“We'll have to use a little strategy,” decided Tom, and then they
+discussed several plans. The one finally adopted was that Tom and Mr.
+Damon should enter the storeroom, casually, as if in search of food to
+cook for supper. They would discuss various dishes, and Mr. Damon was to
+express a preference for something in the food line, the box containing
+which, was well back in the room. This would give the two a chance
+to penetrate to the far end of the apartment, without arousing the
+suspicions of the hidden man, who, doubtless, would be listening to the
+conversation.
+
+“And as soon as we get sight of him, you and I will jump right at him,
+Mr. Damon,” said Tom. “Jump before he has a chance to use his gun. Mr.
+Jenks and Mr. Parker will be waiting outside the room, to catch him if
+he gets away from us. I'll have some ropes ready, and we'll tie him up,
+and--well, we'll decide later what to do with him.”
+
+“All right. I'm ready as soon as you are, Tom,” said the eccentric man.
+“Come ahead.”
+
+They went softly to the storeroom, and listened at the door. There was
+no sound heard save that made by the machinery.
+
+“I wonder if he's really here?” whispered Mr. Damon.
+
+“We'll soon find out,” answered Tom. “Let's go in.”
+
+They entered, and, in pursuance of their plan, Tom and his friend talked
+of various foods.
+
+“I think I'd like some of that canned lobster, with French dressing on,”
+ spoke the eccentric man.
+
+“That's away in the back end of the room,” said Tom, in a loud voice.
+“It's under a lot of boxes.”
+
+“Then I'll help you get it out! Bless my frying pan! but I am very fond
+of lobster!” exclaimed Mr. Damon, in as natural tones as was possible
+under the circumstances.
+
+He and Tom moved cautiously back among the boxes and barrels. They were
+glancing about with eager eyes. Tom switched on an electric light, and,
+the instant he did so, he was aware of a movement in a little space
+formed by one box which was placed on top, of two others. The lad saw a
+dark figure moving, as if to get farther out of sight.
+
+“I've got him!” cried Tom, making a dive for the shadow.
+
+A moment later the young inventor was bowled over, as a dark figure
+leaped over his head.
+
+“Catch him, Mr. Damon!” he cried.
+
+“Bless my hatband! I--I--” Mr. Damon's voice ended in a grunt. He, too,
+had been knocked down by the fleeing man.
+
+“Look out, Mr. Jenks!” cried Tom, to warn those on guard at the door of
+the storeroom.
+
+There was the report of a gun, some excited shouts, and when Tom could
+scramble to his feet, and rush out, he beheld Mr. Parker calmly sitting
+on a struggling man, while Mr. Jenks held a gun, that was still smoking.
+
+“We caught him!” cried the scientist.
+
+“Anybody hurt?” asked Tom, anxiously.
+
+“No, I knocked up his gun as he fired,” explained Mr. Jenks. “Where are
+the ropes, Tom?”
+
+The cords were produced and the man, who had now ceased to struggle,
+was tightly bound. He uttered not a word, but he smiled grimly when Mr.
+Damon remarked:
+
+“I guess I'll go back in the storeroom, Tom, and see how much food he
+ate.”
+
+“Oh, I guess he didn't take much,” declared the lad. “He wasn't there
+long enough.”
+
+“Well, Farley Munson, so it's you, is it?” asked Mr. Jenks, as he
+surveyed the prisoner.
+
+“Do you know him?” asked Tom, in some surprise.
+
+“He was in with the diamond makers,” said Mr. Jenks. “He was one of
+those who took me to the secret cave. But it will be the last time he
+ever goes there. How high up are we, Tom?”
+
+“About two miles. Why?”
+
+“I guess that will be far enough to let him fall,” went on the diamond
+seeker. “Come on, Mr. Damon, help me throw him overboard!”
+
+“You--you're not going to throw me over--with the airship two miles
+high; are you?” gasped the man.
+
+“Will you tell us what we want to know, if we don't?” asked Mr. Jenks.
+
+“What do you want to know?”
+
+“How you got aboard, and what your object was in coming.”
+
+“That's easy enough. I had been hanging around the shed for several
+days, watching a chance to get in. Finally I saw it, when that colored
+man went to feed his mule, and I slipped in, and hid in the airship. The
+stores were all in then, and I stowed myself away among the boxes. I had
+food and water, so I didn't touch any of yours,” and he looked at Mr.
+Damon, who seemed much relieved.
+
+“And what was your object?” demanded Mr. Jenks.
+
+“I wanted to prevent you from going to Phantom Mountain.”
+
+“How?”
+
+“By destroying the airship if need be. But I hoped to accomplish it by
+other means. I would have stopped at nothing, though, to prevent you.
+You must keep away from there!”
+
+“And if we refuse?” asked Tom.
+
+“Then you'll have to take what comes!”
+
+“But not from you!” exclaimed Mr. Jenks. “We're going to get rid of
+you.”
+
+The man's face showed the alarm he felt.
+
+“Oh, don't worry,” said Mr. Jenks, quickly, “we're not going to toss you
+overboard. We're not as desperate as your crowd. But we're going to
+get rid of you, and then go on before you can send any word to your
+confederates. We'll put you off in the most lonesome spot we can find,
+and I guess you'll be some time getting back to civilization. By that
+time we'll have the secret of the diamonds.”
+
+“You never will!” declared the man, firmly. And he would say nothing
+more, though by threats and promises Mr. Jenks tried to get from him
+something about the men in with him, and where the cave of the diamonds
+was located.
+
+Heavily bound with ropes the man was locked in a small closet, to be
+kept there until a favorable spot was reached for letting him go. Mr.
+Jenks' plan, of dropping him down in some place where he would have
+difficulty in sending on word to his confederates was considered a good
+one.
+
+Three days later, in crossing over a lonely region, near the Nebraska
+National Forest, Farley Munson, which was one of the names the spy went
+by, was dropped off the airship, when it was sent down to within a few
+feet of the earth.
+
+“It will take you some time to get to a telegraph office,” said Mr.
+Jenks, as a package of food, and a flask of water was tossed down to the
+stowaway. He shook his fist at those in the airship, and shouted after
+them:
+
+“You'll never discover the secret of Phantom Mountain!”
+
+“Yes, we will,” declared Tom, as he sent the Red Cloud high into the air
+again.
+
+
+
+CHAPTER XI--A WEARY SEARCH
+
+
+During the three days when the stowaway had been kept a prisoner, the
+Red Cloud had made good time on her western trip. She was now about two
+hundred and fifty miles from Leadville, Colorado, and Tom knew he could
+accomplish that distance in a short time. It was necessary, therefore,
+since they were so close to the place where the real search would begin,
+to make some more definite plans.
+
+“We will need to replenish our supply of gasoline,” said Tom, shortly
+after the stowaway had been dropped, and when the young inventor had
+made a general inspection of the airship.
+
+“Is it all gone?” inquired Mr. Damon.
+
+“Not all, but we will soon be in the wildest part of the Rocky
+Mountains, and gasoline is difficult to procure there. So I want to fill
+all our reserve tanks. But I would rather do that before we get far into
+Colorado.”
+
+“Why?” inquired Mr. Parker.
+
+“Because airships are not so common but what the appearance of one
+attracts attention. Ours is sure to be talked about, and commented on.
+In that case, in spite of our precaution in putting Munson off in this
+lonely place, word of the Red Cloud being in the vicinity of Leadville
+may reach the diamond makers, and put them on their guard. We want to
+take them unawares if we can.”
+
+“That's so,” agreed Mr. Jenks. “We had better get our gasoline at the
+first stopping place, then, and proceed with our search. Our first
+object ought to be to look for the landmark--the head of stone. Then we
+can begin to prospect about a bit.”
+
+“My idea, exactly,” declared Tom. “Well, then, I'll go down at the
+first place we cross, where we can get gasoline, and then we'll be in a
+position to hover in the air for a long time, without descending.”
+
+The airship kept on her way, traveling slowly the remainder of that day,
+and at dusk, when there was less chance of big crowds seeing them, the
+Red Cloud was sent down on the outskirts of a large village. Tom and Mr.
+Damon went to a supply store, and arranged to have a sufficient quantity
+of the gasoline taken out to the airship. It was delivered after dark,
+and little talk was occasioned by the few who were aware of the presence
+of the craft. Then, once more, they went aloft, and Tom sent several
+wireless messages to Shopton, including one to Miss Nestor.
+
+“Please tell my wife that I am well, and that I have a good appetite,”
+ said Mr. Damon.
+
+Mr. Parker also sent a message to a scientific friend of his, stating
+that he made some observations among the mountains, of the region in
+which the airship then was, and that the indications were that a great
+landslide would soon take place.
+
+“That won't worry us,” spoke Tom, “for we'll be far above it.”
+
+“I hope we will be near enough to enable me to observe it, and make
+some scientific notes,” came from Mr. Parker. “I am positive that one
+of these mountain peaks that we saw to-day will disappear in a landslide
+within a few days. I have an instrument somewhat like the one that
+records earthquakes, and it has been acting strangely of late.”
+
+Tom wondered what enjoyment Mr. Parker got out of life, when he was
+always looking for some calamity to happen, but the scientist seemed
+to take as much pleasure in his gloomy forebodings now, as he had on
+Earthquake Island.
+
+They reached the vicinity of Leadville the next day, but took care to
+keep high above the city, so that the airship could not be observed.
+With powerful glasses they examined the mountainous country, looking for
+the little settlement of Indian Ridge.
+
+“There it is!” exclaimed Mr. Jenks, just as dusk was settling down. “I
+can make out the hotel I stopped at. Now we can really begin our search.
+The next thing is to find the stone head, and then, I think, I will have
+my bearings.”
+
+“We'll begin the hunt for that landmark in the morning,” said Tom.
+
+High in the air hovered the Red Cloud. At that distance above the earth
+she must have looked like some great bird, and the adventurers thought
+it unlikely that any one in the vicinity of Leadville would observe
+them.
+
+The quest for the great mountain peak, that looked like a stone head,
+was under way. Back and forth sailed the airship. Sometimes she was
+enveloped in fog, and no sight could be had of the earth below. At
+other times there were rain storms, which likewise prevented a view. Mr.
+Parker was on the lookout for his predicted mountain landslide, but it
+did not occur, and he was much disappointed.
+
+“It's queer I can't pick out that landmark,” said Mr. Jenks after two
+days of weary searching, when their eyes were strained from long peering
+through telescopes. “I'm sure it was around Indian Ridge, yet we've
+covered almost all the ground in this neighborhood, and I haven't had a
+glimpse of it.”
+
+“Perhaps it was destroyed in a landslide, or some cataclysm of nature,”
+ suggested Mr. Parker. “That is very possible.”
+
+“If that's the case we're going to have a hard time to locate the cave
+of the diamond makers,” answered Mr. Jenks, “but I hope it isn't so.”
+
+They continued the search for another day, and then Tom, as they sat
+in the comfortable cabin of the airship that night, hovering almost
+motionless (for the motor had been shut down) made a proposition.
+
+“Why not descend in some secluded place,” he suggested, “and wander
+around on foot, making inquiries of the miners. They may know where the
+stone head is, or they may even know about Phantom Mountain.”
+
+“Good idea,” spoke Mr. Jenks. “We'll do it.”
+
+Accordingly, the next morning, the Red Cloud was lowered in a good but
+lonely landing place, and securely moored. It was in a valley, well
+screened from observation, and the craft was not likely to be seen,
+but, to guard against any damage being done to it by passing hunters or
+miners, Mr. Parker and Mr. Damon agreed to remain on guard in it, while
+Tom and Mr. Jenks spent a day or two traveling around, making inquiries.
+
+The young inventor and his companion proceeded on foot to a small
+settlement, where they hired horses on which to make their way about.
+They were to be gone two days, and in that time they hoped to get on the
+right trail.
+
+
+
+
+CHAPTER XII--THE GREAT STONE HEAD
+
+
+It was a wild and desolate country in which Tom Swift and Mr. Jenks
+were traveling. Villages were far apart, and they were at best but
+small settlements. In their journeys from place to place they met few
+travelers.
+
+But of these few they made cautious inquiries as to the location
+of Phantom Mountain, or the landmark known as the great stone head.
+Prospectors, miners and hunters, whom they asked, shook their heads.
+
+“I've heard of Phantom Mountain,” said one grizzled miner, “but I
+couldn't say where it is. Maybe it's only a fish story--the place may
+not even exist.”
+
+“Oh, it does, for I've been there!” exclaimed Mr. Jenks.
+
+“Then why don't you go back to it?” asked the miner.
+
+“Because I can't locate it again,” was the reply.
+
+“Humph! Mighty queer if you've seen a place once, and can't get to it
+again,” and the man looked as if he thought there was something strange
+about Tom and his companion. Mr. Jenks did not want to say that he had
+been taken to the mountain blindfolded, for that would have caused too
+much talk.
+
+“I think if we spent to-night in a place where the miners congregate,
+listened to their talk, and put a few casual questions to them, more as
+if we were only asking out of idle curiosity, we might learn something,”
+ suggested Tom.
+
+“Very well, we'll try that scheme.”
+
+Accordingly, after they had left the suspicious miner the two proceeded
+to a small milling town, not far from Indian Ridge. There they engaged
+rooms for the night at the only hotel, and, after supper they sat around
+the combined dance hall and gambling place.
+
+There were wild, rough scenes, which were distasteful to Tom, and to Mr.
+Jenks, but they felt that this was their only chance to get on the right
+trail, and so they stayed. As strangers in a western mining settlement
+they were made roughly welcome, and in response to their inquiries about
+the country, they were told many tales, some of which were evidently
+gotten up for the benefit of the “tenderfeet.”
+
+“Is there a place around here called Phantom Mountain?” asked Tom, at
+length, as quietly as he could.
+
+“Never heard of it, stranger,” replied a miner who had done most of the
+talking. “I never heard of it, and what Bill Slatterly don't know ain't
+worth knowin'. I'm Bill Slatterly,” he added, lest there be some doubt
+on that score.
+
+“Isn't there some sort of a landmark around here shaped like a great
+stone head?” went on Tom, after some unimportant questions. “Seems to me
+I've heard of that.”
+
+“Nary a one,” answered Mr. Slatterly. “No stone heads, and no Phantom
+Mountains--nary a one.
+
+“Who says there ain't no Phantom Mountains?” demanded an elderly miner,
+who had been dozing in one corner of the room, but who was awakened by
+Slatterly's loud voice. “Who says so?”
+
+“I do,” answered the one who claimed to know everything.
+
+“Then you're wrong!” Tom's heart commenced beating faster than usual.
+
+“Do you mean to say you've seen Phantom Mountain, Jed Nugg?” demanded
+Slatterly.
+
+“No, I ain't exactly seen it, an' I don't want to, but there is such
+a place, about sixty mile from here. Folks says it's haunted, and them
+sort of places I steer clear from.”
+
+“Can you tell me about it?” asked Mr. Jenks, eagerly. “I am interested
+in such things.”
+
+“I can't tell you much about it,” was the reply, “and I wouldn't git too
+interested, if I was you. It might not be healthy. All I know is that
+one time my partner and I were in hard luck. We got grub-staked, and
+went out prospectin'. We strayed into a wild part of the country about
+sixty mile from here, and one night we camped on a mountain--a wild,
+desolate place it was too.”
+
+The miner stopped, and began leisurely filling his pipe.
+
+“Well?” asked Tom, trying not to let his voice sound too eager.
+
+“Well, that was Phantom Mountain.”
+
+The miner seemed to have finished his story.
+
+“Is that all?” asked Mr. Jenks. “How did you know it was Phantom
+Mountain?”
+
+“'Cause we seen the ghost--my partner and I--that's why!” exclaimed the
+man, puffing on his pipe. “As I said, we was campin' there, and 'long
+about midnight we seen somethin' tall and white, and all shimmerin',
+with a sort of yellow fire, slidin' down the side of the mountain. It
+made straight for our camp.”
+
+“Huh! Guess you run, didn't you, Jed?” asked Bill Slatterly.
+
+“Course we did. You'd a run too, if you seen a ghost comm' at you, an'
+firin' a gun.”
+
+“Ghosts can't fire guns!” declared Bill. “I guess you dreamed it, Jed.”
+
+“Ghosts can't fire guns, eh? That's all you know about it. This one did,
+and to prove I didn't dream it, there was a bullet hole in my hat next
+mornin'. I could prove it, too, only I ain't got that hat any more. But
+that was Phantom Mountain, strangers, an' my advice to you is to keep
+away from it. I was on it but I didn't exactly see it, 'cause it was
+dark at the time.”
+
+“Was it near a peak that looked like a stone head?” asked Tom.
+
+“It were, stranger, but I didn't take much notice of it. Me and my
+partner got out of them diggin's next day, and I never went back. I
+ain't never said much about this place, but it's called Phantom Mountain
+all right, and I ain't the only one that's seen a ghost there. Other
+grub-stakers has had the same experience.”
+
+“Why ain't I never heard about it?” demanded Bill, suspiciously.
+
+“'Cause as why you're allers so busy talkin' that you don't never listen
+to nothin' I reckon,” was Jed's answer, amid laughter.
+
+“Can you tell us what trail to take to get there?” asked Tom, of the
+miner.
+
+“Yes, it's called the old silver trail, and you strike it by goin' to a
+place called Black Gulch, about forty mile from here. Then it's twenty
+mile farther on. But take my advice and don't go.”
+
+“Can it be reached by way of Indian Ridge?” asked Mr. Jenks, wondering
+how he had been taken to the cave of the diamond makers. He did not
+remember Black Gulch.
+
+“Yes, you can git there by Indian Ridge way, but it's more dangerous.
+You're likely to lose your way, for that's a trail that's seldom
+traveled.” Mr. Jenks thought that, perhaps, was the reason the gang had
+taken him that way. “It's easier to get to the stone head and Phantom
+Mountain by Black Gulch, but it ain't healthy to go there, strangers,
+take my advice on that,” concluded the miner, as he prepared to go to
+sleep again.
+
+Tom could scarcely contain the exultation he felt. At last, it seemed,
+they were on the trail. He motioned to Mr. Jenks, and they slipped
+quietly from the place, just as another dance was beginning.
+
+“Now for Black Gulch!” cried Tom. “We must hurry back to the airship,
+and tell the good news.
+
+“It's too late to-night,” decided Mr. Jenks, and so they waited until
+morning, when they made an early start.
+
+They found Mr. Damon and Mr. Parker anxiously awaiting their return. Mr.
+Damon blessed so many things that he was nearly out of breath, and Mr.
+Parker related something of the observations he had made.
+
+“I think I have discovered traces of a dormant volcano,” he said. “I am
+in hopes that it will have an eruption while we are here.”
+
+“I'm not,” spoke Tom, decidedly. “We'll start for Black Gulch as soon as
+possible.”
+
+The airship once more rose in the air, and, following the directions
+the miner had given him, Tom pointed his craft for the depression in the
+mountains which had been given the name Black Gulch. It was reached in
+a short time, and then, making a turn up a long valley the airship
+proceeded at reduced speed.
+
+“We ought to see that stone head soon now,” spoke Tom, as he peered from
+the windows of the pilot house.
+
+“It's queer we didn't notice it when we were up in the air,” remarked
+Mr. Jenks. “We've been over this place before, I'm sure of it.”
+
+The next moment Mr. Damon uttered a cry. “Bless my watch-chain!” he
+exclaimed. “Look at that!”
+
+He pointed off to the left. There, jutting out from the side of a steep
+mountain peak was a mass of stone--black stone--which, as the airship
+slowly approached, took the form and shape of a giant's head.
+
+“That's it! That's it!” cried Tom. “The great stone head!”
+
+“And now for Phantom Mountain and the diamonds!” shouted Mr. Jenks, as
+Tom let the airship slowly settle to the bottom of the valley.
+
+
+
+
+CHAPTER XIII--ON PHANTOM MOUNTAIN
+
+
+Out from the Red Cloud piled Tom and the others. They made a rush for
+the irregular mass of rock which bore so strong a resemblance to the
+head of some gigantic man.
+
+“That's the one! That's the thing I saw when they were taking me along
+here blindfolded!” exclaimed Mr. Jenks. “I'm sure we're on the right
+trail, now!”
+
+“But what gets me, though,” remarked Mr. Damon, “is why we couldn't see
+that landmark when we were up in the air. We had a fine view, and ought
+to have been able to pick it out with the telescopes.”
+
+The adventurers saw the reason a few seconds later. The image was
+visible only from one place, and that was directly looking up the
+valley. If one went too far to the right or left the head disappeared
+from view behind jutting crags, and it was impossible to see it from
+overhead, because the head was almost under a great spur of a mighty
+mountain.
+
+“We might have hunted for it a week in the airship, and been directly
+over it,” said Tom, “and yet we would never have seen it.”
+
+“Yes, but we never would have gotten here in such good shape if it
+hadn't been for your wonderful craft,” declared Mr. Jenks. “It brought
+us here safely and quickly, and enabled us to elude the men who tried to
+keep us back. We're here in spite of them. If we had traveled by train
+they might have interfered with us in a dozen ways.”
+
+“That's so,” agreed Mr. Damon. “Well, now we're here, what's to be
+done? Which way do we start to reach the cave where the diamonds are
+manufactured, Mr. Jenks?”
+
+“That I can't say. As you know, I only had a momentary glimpse of this
+stone head as they were taking me along the trail. Then one of the men
+noticed that the bandage had slipped and he pulled it into place. So I
+really can't say which direction to take now, in order to discover the
+secret.”
+
+“How long after you saw the head before you reached the cave?” asked
+Tom. “In that way we may be able to tell how far away it is.”
+
+“Well, I should say it was about two or three hours after I saw the
+head, before we got to the halting place, and I was carried into the
+cave. That would make it several miles from here, for we went in a
+wagon.”
+
+“Yes, and they might have driven in a round-about way, in order to
+deceive you,” suggested Mr. Damon. “At best we have but a faint idea
+where the diamond cave is, but we must search for it; eh, Tom?”
+
+“Certainly. We'll start right in. And as the airship will be of but
+little service to us now, I suggest that we leave it in this valley.
+It is very much secluded, and no one will harm it, I think. We can then
+start off prospecting, for I have a large portable tent, and we can
+carry enough food with us, with what game we can shoot, to enable us to
+live. I have a regular camping outfit on board.”
+
+“Fine!” cried Mr. Parker, “and that will give me a chance to make some
+observations among the mountains, and perhaps I can predict when a
+landslide, or an eruption of some dormant volcano, may occur.”
+
+“Bless my stars!” cried Mr. Damon. “I don't wish you any bad luck, Mr.
+Parker, but I sincerely hope nothing of the sort happens! We had enough
+of that on Earthquake Island!”
+
+“One can not halt the forces of nature,” said the scientist, solemnly.
+“There are many towering peaks around here which may contain old
+volcanoes. And I notice the presence of iron ore all about. This must be
+a wonderful place in a thunder and lightning storm.”
+
+“Why?” asked Tom, curiously.
+
+“Because lightning would be powerfully attracted here by the presence
+of the metal. In fact there is evidence that many of the peaks have been
+struck by lightning,” and the scientist showed curious, livid scars on
+the stone faces of the peaks within sight.
+
+“Then this is a good place to stay away from in a storm,” observed Mr.
+Damon. “However, we won't worry about that now. If this is the landmark
+Mr. Jenks was searching for, then we must be in the vicinity of Phantom
+Mountain.”
+
+“I think we are,” declared the diamond seeker. “Probably it is within
+sight now, but there are so many peaks, and this is such a wild and
+desolate part of the country that we may have trouble in locating it.”
+
+“We've got to make a beginning, anyhow,” decided Tom, “and the sooner
+the better. Come, we'll make up our camping kits, and start out.”
+
+It was something to know that they were on the right trail, and it was a
+relief to be able to busy oneself, and not be aimlessly searching for a
+mysterious landmark. They all felt this, and soon the airship was taken
+to a secluded part of the valley, where it was well hidden from sight in
+a grove of trees.
+
+Tom and Mr. Damon then served a good meal, and preparations were made
+to start on their search among the mountains--a search which they hoped
+would lead them to Phantom Mountain, and the cave of the diamond makers.
+
+The tent which would afford them shelter was in sections, and could
+be laced together. They carried food, compressed into small packages,
+coffee, a few cooking utensils; and each one had a gun, Tom carrying a
+combination rifle and shotgun, for game.
+
+“We can't live very high while we're on the trail,” said the young
+inventor, “but it won't be much worse than it was on Earthquake Island.
+Are we all ready?”
+
+“I guess so,” answered Mr. Damon. “How long are we going to be away?”
+
+“Until we find the diamond makers!” declared Tom, firmly.
+
+Shouldering their packs, the adventurers started off. Tom turned for a
+last look at his airship, dimly seen amid the trees. Would he ever come
+back to the Red Cloud? Would she be there when he did return? Would
+their quest be successful? These questions the lad asked himself, as he
+followed his companions along the rocky trail.
+
+“Perhaps we can find the road by which these men go in and out of the
+cave,” suggested Mr. Damon, when they had gone on for several miles.
+
+“I fancy not,” replied Mr. Jenks. “They probably take great pains to
+hide it. I think though, that our best plan will be to go here and
+there, looking for the entrance to the cave. I believe I would remember
+the place.”
+
+“But why can't you follow the directions given by the miner who told you
+about Phantom Mountain?” asked Mr. Damon.
+
+“Because his talk was too indefinite,” answered Mr. Jenks. “He was so
+frightened by seeing what he believed to be a ghost, that he didn't take
+much notice of the location of the place. All he knows is that Phantom
+Mountain is somewhere around here.”
+
+“And we've got to hunt until we find it; is that the idea?” asked Mr.
+Parker.
+
+“Or until we see the phantom,” added Tom, in a low voice.
+
+“Bless my topknot!” exclaimed Mr. Damon. “You don't mean to say you
+expect to see that ghost; do you Tom?”
+
+“Perhaps,” answered the young inventor, and he did not add something
+else of which he was thinking. For Tom had a curious theory regarding
+the phantom.
+
+They tramped about the remainder of that day. Toward evening Tom shot
+some birds, which made a welcome addition to their supper. Then the tent
+was put together, some spruce and hemlock boughs were cut to make a soft
+bed, and on these, while the light of a campfire gleamed in on them, the
+adventurers slept.
+
+Their experience the following day was similar to the first. They saw no
+evidence of a large cave such as Mr. Jenks had described, nor were there
+any traces of men having gone back and forth among the mountains, as
+might have been expected of the diamond makers, for, as Mr. Jenks had
+said, they made frequent journeys to the settlement for food, and other
+supplies.
+
+“Well, I haven't begun to give up yet,” announced Tom, on the third day,
+when their quest was still unsuccessful. “But I think we are making one
+mistake.”
+
+“What is that?” inquired Mr. Jenks.
+
+“I think we should go up higher. In my opinion the cave is near the top
+of some peak; isn't it, Mr. Jenks?”
+
+“I have that impression, though, as you know, I never saw the outside of
+it. Still, it might not be a bad idea to ascend some of these peaks.”
+
+Following this suggestion, they laid their trail more toward the sky,
+and that night found them encamped several thousand feet above the
+sea-level. It was quite cool, and the campfire was a big one about which
+they sat after supper, talking of many things.
+
+Tom did not sleep well that night. He tossed from side to side on the
+bed of boughs, and once or twice got up to replenish the fire, which had
+burned low. His companions were in deep slumber.
+
+“I wonder what time it is?” mused Tom, when he had been up the third
+time to throw wood on the blaze. “Must be near morning.” He looked at
+his watch, and was somewhat startled to see that it was only a little
+after twelve. Somehow it seemed much later.
+
+As he was putting the timepiece back into his pocket the lad looked
+around at the dark and gloomy mountains, amid which they were encamped.
+As his gaze wandered toward the peak of the one on the side of which the
+tent was pitched, he gave a start of surprise.
+
+For, coming down a place where, that afternoon, Tom had noticed a sort
+of indefinite trail was a figure in white. A tall, waving figure, which
+swayed this way and that--a figure which halted and then came on again.
+
+“I wonder--I wonder if that can be a wisp of fog?” mused the young
+inventor. He rubbed his eyes, thinking it might be a swirling of the
+night mist or a defect of vision. Then, as he saw more plainly, he
+noticed the thing in white rushing toward him.
+
+“It's the phantom--the phantom!” cried Tom, aloud. “It's the thing the
+miner saw! We're on Phantom Mountain now!”
+
+
+
+
+CHAPTER XIV--WARNED BACK
+
+
+Tom's cries awakened the sleepers in the tent. Mr. Damon was the first
+to rush out.
+
+“Bless my nightcap, Tom!” he cried. “What is it? What has happened? Are
+we attacked by a mountain lion?”
+
+For answer the young inventor pointed up the mountain, to where, in the
+dim light from a crescent moon, there stood boldly revealed, the figure
+in white.
+
+“Bless--bless my very existence!” cried the odd man. “What is it, Tom?”
+
+“The phantom,” was the quiet answer. “Watch it, and see what it does.”
+
+By this time Mr. Jenks and Mr. Parker had joined Tom and Mr. Damon.
+The four diamond seekers stood gazing at the apparition. And, as they
+looked, the thing in white, seemingly too tall for any human being, slid
+slowly forward, with a gliding motion. Then it raised its long, white
+arms, and waved them threateningly at the adventurers.
+
+“It's motioning us to go back,” said Mr. Parker in an awed whisper. “It
+doesn't want us to go any farther.”
+
+“Very likely,” agreed Tom, coolly. “But we're not going to be frightened
+by anything like that; are we?”
+
+“Not much!” exclaimed Mr. Jenks. “I expected this. A ghost can't drive
+me back from getting my rights from those scoundrels!”
+
+“Suppose it uses a revolver to back up its demand?” asked the scientist.
+
+“Wait until it does,” answered Mr. Jenks. But the figure in white
+evidently had no such intentions. It came on a little distance
+farther, still waving the long arms threateningly, and then it suddenly
+disappeared, seeming to dissolve in the misty shadows of the night.
+
+“Bless my suspenders!” cried Mr. Damon. “That's a very strange
+proceeding! Very strange! What do you make of it, Tom?”
+
+“It is evidently some man dressed up in a sheet,” declared Mr. Jenks. “I
+expected as much.”
+
+“The work of those diamond makers; do you think?” continued Mr. Damon.
+
+“I believe so,” answered Tom, slowly, for he was trying to think it out.
+“I believe they are the cause of the phantom, though I don't know that
+it's a man dressed in a sheet.”
+
+“Why isn't it?” demanded Mr. Jenks.
+
+“Because it was too tall for a man, unless he's a giant.”
+
+“He may have been on stilts,” suggested Mr. Parker.
+
+“No man on stilts could walk along that way,” declared Tom, confidently.
+“He glided along too easily. I am inclined to think it may be some sort
+of a light.”
+
+“A light?” queried Mr. Damon.
+
+“Yes, the diamond makers may be hidden in some small cave near here, and
+they may have some sort of a magic lantern or a similar arrangement, for
+throwing a shadow picture. They could arrange it to move as they liked,
+and could cause it to disappear at will. That, I think, is the ghost we
+have just seen.”
+
+“But the diamond makers have only been in this mountain recently,”
+ objected Mr. Jenks, “and the phantom was here before them. In fact, that
+was what gave the place its name.”
+
+“That may be,” admitted the lad. “There are many places that have the
+name of being haunted, but no one ever sees the ghost. It is always some
+one else, who has heard of some one who has seen it. That may have been
+the case here. I grant that this place may have been called 'Phantom
+Mountain' for a number of years, due to the superstitious tales of
+miners. The diamond makers came along, found the conditions just right
+for their work, and adopted the ghost, so to speak. As there wasn't any
+real spirit they made one, and they use it to scare people away. I think
+that's what we've just seen, though I may be wrong in my theory as to
+what the phantom is.”
+
+“Well, it's gone now, at any rate,” said Mr. Jenks, “and I think we'd
+better get back inside the tent. It's cold out here.”
+
+“Aren't some of us going to stand guard?” demanded Mr. Damon.
+
+“What for?” asked Mr. Jenks.
+
+“Why--er--bless my key-ring! Suppose that ghost takes a notion to come
+down here, and use his gun, as he did on the miners?”
+
+“I don't believe that will happen,” remarked Tom. “The diamond makers,
+if the white thing had anything to do with them, have given us a
+warning, and I think they'll at least wait until morning to see how we
+heed it.”
+
+“We aren't going to heed it!” burst out Mr. Jenks. “I'm going to go
+right ahead and find that cave where they make diamonds!”
+
+“And we're with you!” exclaimed Tom. “We'll have a good fire going the
+rest of the night, and that may keep intruders away. In the morning
+we'll begin our search, and we'll go up the trail where we saw the white
+figure.”
+
+A big pile of wood had been collected for the fire, and Tom now piled
+some logs and branches on the blaze. It would last for some time now,
+and the adventurers, still talking of the “ghost” went back into the
+tent. It was over an hour before they all got to sleep again, and Mr.
+Jenks and Mr. Damon took turns in getting up once or twice during the
+remainder of the night to replenish the fire.
+
+Morning dawned without anything further having occurred to disturb them,
+and, after a hearty breakfast, to which Tom added some fish he caught in
+a nearby mountain stream, they set off up the trail on Phantom Mountain.
+
+They had left their tent standing, as they proposed making that spot
+their headquarters until they located the cave they were seeking. What
+their course would be after that would depend on the circumstances.
+
+If they had expected to have an easy task locating the cavern in which
+Mr. Jenks had seen diamonds made, the adventurers were disappointed. All
+that day they tramped up and down the mountain, looking for some secret
+entrance, but none was disclosed. The higher they went up the great
+peak, the fainter became the trail, until, at length it vanished
+completely.
+
+But this was not to be wondered at, since it was on solid rock, in which
+no footsteps would leave an impression.
+
+“They never brought you up here in a wagon, Mr. Jenks,” decided Tom,
+when he saw how steep the place was.
+
+“I'm inclined to think so myself,” admitted the diamond man. “They must
+have reached the cave from some other way. As a matter of fact, I walked
+some distance after getting out of the vehicle, before we got to the
+cavern. But, even at that, I don't believe we came this way.”
+
+“Yet the phantom was here,” persisted Tom, “and I'm convinced that the
+cave is in this neighborhood. It's up to us to find it!”
+
+But they searched the remainder of that day in vain, and as night was
+coming on, they made their way back to the camp. As Tom, who was in
+the lead, approached the tent, he saw something black fastened to the
+entrance.
+
+“Hello!” he cried. “Some one's been here. That wasn't on the tent when
+we left this morning.”
+
+“What is it?” asked Mr. Damon.
+
+“A black piece of paper, written on with white ink,” replied the lad. He
+was reading it, and, as he perused it a look of surprise came over his
+face.
+
+“Listen to this!” called Tom. “It's evidently from the diamond makers.”
+
+Holding up the black paper, on which the white writing stood out in bold
+relief Tom read aloud:
+
+
+“Be warned in time! Go back before it is too late! You are near to
+death! Go back!”
+
+
+“Bless my shoelaces!” cried Mr. Damon. “This is getting serious.”
+
+
+
+
+CHAPTER XV--THE LANDSLIDE
+
+
+Gathered about the young inventor, the three men looked at the warning.
+The writing was poor, and it was evident that an attempt had been made
+to disguise it. But there was no misspelling of words, and there were no
+rudely drawn daggers, or bloody hands or anything of that sort. In fact,
+it was a very business-like sort of warning.
+
+“Rather odd,” commented Mr. Jenks. “Black paper and white ink.”
+
+“White ink is easy enough to make,” stated Mr. Parker. “I fancy they
+wanted it as conspicuous as possible.”
+
+“Yes,” agreed Tom, “and this warning, together with the antics of the
+thing in white last night, shows that they are aware of our presence
+here, and perhaps know who we are. We will have to be on our guard.”
+
+“Do you think that fellow Munson, whom we left in the forest, could have
+gotten here and warned them?” asked Mr. Damon.
+
+“It's possible,” admitted Tom, “but now let's see if the person who
+pinned this warning on our tent took any of our things.”
+
+A hasty examination, however, showed that nothing had been disturbed,
+and Tom and Mr. Damon were soon getting supper ready, everyone talking,
+during the progress of the meal, about the events of the day, and the
+rather weird culmination of it.
+
+“Well, we haven't had a great deal of success--so far,” admitted Tom, as
+they sat about the fire, in the fast gathering dusk. “I think, perhaps,
+we'd better try on the other side of the mountain to-morrow. We've
+explored this side pretty thoroughly.”
+
+“Good idea,” commented Mr. Jenks. “We'll do it, and move our camp. I
+only hope those fellows don't find our airship and destroy it. We'll
+have a hard time getting back to civilization again, if we have to walk
+all the way.”
+
+This contingency caused Tom some uneasiness. He did not like to think
+that the unscrupulous men might damage the Red Cloud, that had been
+built only after hard labor. But he knew he could accomplish nothing by
+worrying, and he tried to dismiss the matter from his mind.
+
+They rather expected to see the thing in white again that night, but it
+did not appear, and morning came without anything having disturbed their
+heavy sleep, for they were tired from the day's tramp.
+
+It took them the greater part of the day to make a circuit of the base
+of Phantom Mountain in order to get to a place where a sort of trail led
+upward.
+
+“It's too late to do anything to-night,” decided Tom, as they set up the
+tent. “We'll rest, and start the first thing in the morning.”
+
+“And the ghost isn't likely to find us here,” added Mr. Damon. “Where
+are you going, Mr. Parker?” he asked, as he saw the scientist tramping a
+little way up the side of the mountain.
+
+“I am going to make some observations,” was the answer, and no one paid
+any more attention to him for some time. Supper was nearly ready when
+Mr. Parker returned. His face wore a rather serious air, and Mr. Damon,
+noting it, asked laughingly:
+
+“Well, did you discover any volcanoes, that may erupt during the night,
+and scare us to death?”
+
+“No,” replied Mr. Parker, calmly, “but there is every indication that we
+will soon have a terrific electrical storm. From a high peak I caught a
+glimpse of one working this way across the mountains.”
+
+“Then we'd better fasten the tent well down,” called Tom. “We don't want
+it to blow away.”
+
+“There will not be much danger from wind,” was Mr. Parker's opinion.
+
+“From what then?” asked Mr. Jenks.
+
+“From the discharges of lightning among these mountain peaks, which
+contain so much iron ore. We will be in grave danger.”
+
+The fact that the scientist had not always made correct predictions was
+not now considered by his hearers, and Tom and the two men gazed at Mr.
+Parker in some alarm.
+
+“Is there anything we can do to avoid it?” asked Mr. Jenks.
+
+“The only thing to do would be to leave the mountain,” was the answer,
+“and, as the iron ore extends for miles, we can not get out of the
+danger zone before the storm will reach us. It will be here in less than
+half an hour.”
+
+“Then we'd better have supper,” remarked Tom, practically, “and get
+ready for it. Perhaps it may not be as bad as Mr. Parker fears.”
+
+“It will be bad enough,” declared the gloomy scientist, and he seemed to
+find pleasure in his announcement.
+
+The meal was soon over, and Tom busied himself in looking to the guy
+ropes of the tent, for he feared lest there might be wind with the
+storm. That it was coming was evident, for now low mutterings of thunder
+could be heard off toward the west.
+
+Black clouds rapidly obscured the heavens, and the sound of thunder
+increased. Fitful flashes of lightning could be seen forking across the
+sky in jagged chains of purple light.
+
+“It's going to be a heavy storm,” Tom admitted to himself. “I hope
+lightning doesn't strike around here.”
+
+The storm came on rapidly, but there was a curious quietness in the air
+that was more alarming than if a wind had blown. The campfire burned
+steadily, and there was a certain oppressiveness in the atmosphere.
+
+It was now quite dark, save when the fitful lightning flashes came,
+and they illuminated the scene brilliantly for a few seconds. Then, by
+contrast, it was blacker than ever.
+
+Suddenly, as Tom was gazing up toward the peak of Phantom Mountain, he
+saw something that caused him to cry out in alarm. He pointed upward,
+and whispered hoarsely:
+
+“The ghost again! There's our friend in white!”
+
+The others looked, and saw the same weird figure that had menaced them
+when they were encamped on the other side of the peak.
+
+“They must have followed us,” said Mr. Jenks, in a low voice.
+
+Slowly the figure advanced, It waved the long white arms, as if in
+warning. At times it would be only dimly visible in the blackness, then,
+suddenly it would stand out in bold relief as a great flash of fire
+split the clouds.
+
+The thunder, meanwhile, had been growing louder and sharper, indicating
+the nearer approach of the storm. Each lightning flash was followed in a
+second or two, by a terrific clap. Still there was no wind nor rain, and
+the campfire burned steadily.
+
+All at once there was a crash as if the very mountain had split asunder,
+and the adventurers saw a great ball of purple-bluish fire shoot down,
+as if from some cloud, and strike against the side of the crag, not a
+hundred feet from where stood the ghostly figure in white.
+
+“That was a bad one,” cried Mr. Damon, shouting so as to be heard above
+the echoes of the thunderclap.
+
+Almost as he spoke there came another explosion, even louder than the
+one preceding. A great ball of fire, pear shaped, leaped for the same
+spot in the mountain.
+
+“There's a mass of iron ore there!” yelled Mr. Parker. “The lightning is
+attracted to it!”
+
+His voice was swallowed up in the terrific crash that followed, and,
+as there came another flash of the celestial fire, the figure in
+white could be seen hurrying back up the mountain trail. Evidently the
+electrical storm, with lightning bolts discharging so close, was too
+much for the “ghost.”
+
+In another instant it looked as if the whole place about where the
+diamond seekers stood, was a mass of fire. Great forked tongues of
+lightning leaped from the clouds, and seemed to lick the ground. There
+was a rattle and bang of thunder, like the firing of a battery of guns.
+Tom and the others felt themselves tingling all over, as if they had
+hold of an electrical battery, and there was a strong smell of sulphur
+in the air.
+
+“We are in the midst of the storm!” cried Mr. Parker. “We are standing
+on a mass of iron ore! Any minute may be our last!”
+
+But fate had not intended the adventurers for death by lightning. Almost
+as suddenly as it had begun, the discharge of the tongues of fire ceased
+in the immediate vicinity of our friends. They stood still--awed--not
+knowing what to do.
+
+Then, once more, came a terrific clap! A great mass of fire, like some
+red-hot ingot from a foundry, was hurled through the air, straight at
+the face of the mountain, and at the spot where the figure in white had
+stood but a few minutes before.
+
+Instantly the earth trembled, as it had at Earthquake Island, but it was
+not the same. It was over in a few seconds. Then, as the diamond seekers
+looked, they saw in the glare of a score of lightning flashes that
+followed the one great clap, the whole side of the mountain slip away,
+and go crashing into the valley below.
+
+“A landslide!” cried Mr. Parker. “That is the landslide which I
+predicted! The lightning bolt has split Phantom Mountain!”
+
+
+
+
+CHAPTER XVI--THE VAST CAVERN
+
+
+For a time the roiling, slipping, sliding and tumbling of the mass of
+earth and stones, down the side of the mountain, effectually drowned
+all other sounds. Even the thunder was stilled, and though Tom and his
+companions called to one another in terror, their voices could not rise
+above that terrific tumult.
+
+Finally, when they found that the direction of the slide was away from
+their tent, and that they were not likely to be engulfed, they grew more
+calm.
+
+Gradually the noise subsided. The great boulders had rolled to the
+bottom of the valley, and now only a mass of earth and stones was
+sliding down. Even this stopped in about five minutes, and, as though
+satisfied with what it had done, the electrical storm passed. Not a drop
+of rain had fallen.
+
+“Bless my shirt studs!” exclaimed Mr. Damon, who was the first to speak
+after the din had quieted. “Bless my soul! But that was awful!”
+
+“It was just what I expected,” said Mr. Parker, calmly. “I knew, from
+my observations, that we were in a region where landslides and terrific
+electrical storms may be expected at any time. I fully looked for this.”
+
+“Well,” remarked Mr. Jenks, rather sarcastically, “I hope it came up to
+your expectations, Mr. Parker.”
+
+“Oh, fully,” was the answer, “though I wish it could have happened
+in daylight, so that I could better have observed certain phenomena
+regarding the landslide. They are very interesting.”
+
+“At a distance,” admitted Tom, with a laugh of relief. “Well, I'm glad
+it's over, though we'll have to wait until morning to see what damage
+has been done. Lucky we weren't struck by lightning. I never saw such
+bolts!”
+
+“Me, either!” declared Mr. Damon. “This mountain seems to attract them.”
+
+“It is like a magnet,” said Mr. Parker. “I think I shall be able to make
+some fine observations here.”
+
+“If we live through it,” murmured Mr. Jenks.
+
+They watched the play of lightning about a distant bank of clouds,
+but the storm was now far away, only a faint rumbling of thunder being
+heard.
+
+“I'm wondering what happened to the phantom,” said Tom, after a pause.
+“Seems to me he was right in that track of the storm.”
+
+“Do you think it was a 'he'?” asked Mr. Jenks.
+
+“I think we'll find that it's some sort of a man,” answered the young
+inventor. “We may find out very soon, now. I've changed my theory about
+the ghost being reflections of light.”
+
+“How's that?” Mr. Damon wanted to know.
+
+“Well, I think we are on the side of Phantom Mountain where the diamond
+cave is,” went on the lad. “The fact that the phantom appeared here,
+soon after we arrived, shows that the men kept close track of our
+movements. It also shows, I think, that the phantom did not have to
+travel far to be on the spot, whereas we had to make quite a trip to get
+around the base of the mountain. I think the cave is up there,” and
+Tom pointed toward the spot where the weird figure had been last seen,
+before the storm drove it back.
+
+“There may be two phantoms,” suggested Mr. Jenks. “They may keep one on
+this side of the mountain, and one on the other, to warn intruders away.
+
+“It's possible,” admitted Tom. “Well, we'll see how things look in the
+morning, when we'll take up our march again, and go up the mountain.
+We'll reach the top, if possible, which we couldn't do from the other
+side, as it was too steep.”
+
+“I hope we shall be able to go forward in the morning,” came from Mr.
+Jenks.
+
+“What do you mean?” asked the lad, struck by a peculiar significance in
+the diamond man's tones.
+
+“Why, that landslide may have opened a great gully in the side of
+Phantom Mountain, which will prevent us from passing. It was a terrific
+lot of earth and stones that slid away,” answered Mr. Jenks.
+
+“It certainly was,” agreed Mr. Parker. “I would not be surprised if
+the mountain was half destroyed, and it may be that the diamond cave no
+longer exists.”
+
+“Not very cheerful, to say the least,” murmured Mr. Jenks to Tom, and,
+as it was getting quite chilly, following the storm, they went inside
+the tent.
+
+Tom could hardly wait for daylight, to get up and see what havoc the
+landslide had wrought. As soon as the first faint flush of dawn showed
+over the eastern peaks, he hurried from the tent. Mr. Damon heard him
+arise, and followed.
+
+A curious scene met their eyes. All about were great rocks rent and torn
+by the awful power of the lightning. The fronts of the stone cliffs
+were scarred and burned by the electrical fire, and fantastic markings,
+grotesque faces, and leering animals seemed to have been drawn by some
+gigantic artist who used a bolt from heaven for his brush.
+
+But the eyes of Tom and Mr. Damon took all this in at a glance, and then
+their gaze went forward to where the avalanche had torn away a great
+part of the mountain.
+
+“Whew! I should say it was a landslide!” cried Tom.
+
+“Bless my wishbone, yes!” agreed Mr. Damon.
+
+Below them, in the valley, lay piled immense masses of earth and stones.
+Boulders were heaped up on boulders, and rocks upon rocks, being tossed
+about in heaps, strung about in long ridges, and swirled about in
+curves, as though some cyclone had toyed with them after the lightning
+flash had tossed them there.
+
+“But the mountain isn't half gone,” said Tom, as his eyes took in what
+was left of the phantom berg. “I guess it will take a few more bolts
+like that one, to put this hill out of business.”
+
+Though the landslide had been a great one, the larger part of the
+mountain still stood. An immense slice had been taken from one side, but
+the summit was untouched.
+
+“And there's where the diamond cave is!” cried Tom, pointing to it.
+
+“I think so myself,” agreed Mr. Jenks, who came from the tent at that
+moment, and joined the lad and Mr. Damon. “I think we shall find the
+cave somewhere up there. We must start for it, as soon as we have eaten,
+and we may reach it by night.”
+
+The three stood gazing up toward the summit of the great mountain.
+Suddenly, as the sun rose higher in the heavens, it sent a shaft of rosy
+light on the face of the berg that had been scarred by the landslide.
+Tom Swift uttered an exclamation, and pointed at something.
+
+“See!” he cried. “Look where the trail is--the trail down which the
+phantom must have come. It is on the edge of a cliff now!”
+
+They looked, and saw that this was so. The increasing light had just
+revealed it to them. When the lightning bolt had torn away a great
+portion of the mountain it had cut sheer down for a great depth and
+when the earth and stones fell away they left a narrow pathway, winding
+around the mountain, but so near the edge of a great chasm, that there
+was room but for one person at a time to walk on that footway. The
+uncertain trail up Phantom Mountain had all but been destroyed.
+
+“The way up to the peak is by that path, now,” spoke Tom, in a low
+voice.
+
+“Bless my soul!” cried Mr. Damon. “It's as much as a man's life is worth
+to attempt it. If he got dizzy, he'd topple over, and fall a thousand
+feet. Dare we risk it?”
+
+“It's the only way to get up,” went on Tom. “It's either that way, or
+not at all. We've tried the other side without success. We must go up
+this way--or turn back.”
+
+“Then we'll go up!” cried Mr. Jenks. “It may not be as dangerous as it
+looks from here.”
+
+But it was even more dangerous than it appeared, when they went part way
+up it after a hasty breakfast. The trail was a mere ledge of rock now,
+and in some places, to get around a projecting edge of the mountain,
+they had to stand with their backs to the dizzy depths at their feet,
+and with both arms outstretched work their way around to where the trail
+was wider.
+
+“Shall we risk it?” asked Tom, when they had tried the way, and found
+it so dangerous. “We can't take anything with us--even our guns, for
+we couldn't carry them, and if we reach the mouth of the cave, and find
+those men there--”
+
+He paused significantly. The adventurers looked at one another. The
+search for the diamond makers was becoming more and more dangerous.
+
+“I say let's go on!” decided Mr. Damon, suddenly. “We want to locate
+that cave, first of all. Perhaps, when we do find it, we may see some
+easier way of getting to it than this. And if those diamond makers do
+attack us--well, I don't believe they'll shoot defenseless men, and they
+may listen to reason, and give Mr. Jenks his rights--tell him how to
+make diamonds in return for the money he gave them.”
+
+“I don't believe those scoundrels will listen to reason,” replied the
+diamond man, “but I agree with Mr. Damon that we ought to go on. We may
+find some other means of reaching the cave--if we can discover it, and
+we'll take a chance with the men.”
+
+“Forward it is, then!” cried Tom. “I have a revolver, and I can supply
+one of you gentlemen with another. They may come in useful in an
+emergency. Let's go back to camp, take a little lunch in our pockets,
+and try to scale the mountain.”
+
+They were soon on their way up the dizzy path once more, and, as they
+advanced, they found it growing more and more dangerous. In some places
+they found it almost impossible to get around certain corners, where
+there was barely room for their feet. As Tom remarked grimly, a fat man
+never could have done it. Fortunately they were all comparatively thin,
+for their hard work, and not too abundant food, since they had left the
+airship, had reduced their weight.
+
+Up and up they went, higher and higher, sometimes finding the path wide
+enough for two to walk abreast, and again seeing it narrow almost to
+a ribbon. They hardly dared look down into the chasm at their left--a
+chasm filled, in part, with the rocks and boulders tossed into it by the
+lightning bolt.
+
+Tom was in the lead, and had just made a dangerous turn around a
+shoulder of rock--one of those places where he had to extend both arms,
+and fairly hug the cliff before he could get around.
+
+But, when he had made it, and found himself on a broad pathway, cut
+in the living rock, he gave a great shout--a shout that caused his
+companions to hasten to his side. They found the young inventor pointing
+to a clump of bushes and small trees.
+
+But it was not the shrubbery that Tom desired to call to their
+attention. They saw that in an instant, for, dimly seen through the
+leaves, was something black, and, as they looked more closely, they saw
+that it was a great hole in the side of the mountain--a vast cavern,
+opening like a tunnel.
+
+“The cave! The cave!” cried Tom. “The diamond makers' cave!”
+
+Hardly had he spoken than two men, each one carrying a gun, showed
+themselves in the mouth of the cavern, and, instant later they both ran
+toward the little party of adventurers.
+
+
+
+
+CHAPTER XVII--THE PHANTOM CAPTURED
+
+
+Surprise held Tom and his friends almost spellbound for the moment.
+The young inventor's hand went toward the pocket where he carried his
+revolver. Mr. Jenks, who had the only other weapon, sought to draw it,
+but he was stopped by a gesture of one of the two men with guns.
+
+“Hold on, strangers!” the man cried. “I know what you're up to! Better
+not try to draw anything--it might not be healthy. Now, then, who are
+you, and what do you want?”
+
+The question came rather as a surprise, at least to Tom and Mr. Jenks.
+They had taken it for granted that these men--if they were the diamond
+makers--would know Mr. Jenks, and guess at his errand in coming back
+to Phantom Mountain. But, it seemed, that they took them all for casual
+strangers.
+
+No one answered for a moment. Tom caught the eye of Mr. Jenks, and there
+was a look of hope in it. If ever there was a time for strategy, it was
+now. Evidently Munson, the stowaway on the airship, had not yet been
+able to send a warning to his confederates. And neither of the two men
+recognized Mr. Jenks as the man who had been defrauded of his rights.
+It might be possible to conceal the real object of the adventurers until
+they had time to formulate a plan of action.
+
+“Well,” exclaimed the man with the gun, impatiently, “I ask you folks a
+question. What do you want?”
+
+Fortunately, neither Mr. Damon nor Mr. Parker replied. The former
+because he deferred to Tom and Mr. Jenks, and the scientist because he
+was busy inspecting some curious rocks he picked up. As it turned out
+this was the luckiest thing he could have done. It lent color to what
+Mr. Jenks said a moment later.
+
+“What are you doing up here?” demanded the man again. “Don't you know
+this is private property?”
+
+“We--we were just looking around,” answered Mr. Jenks, which was true
+enough; as far as it went.
+
+“Prospecting,” added Tom.
+
+“After gold?” demanded the second man, suspiciously.
+
+“We'd be glad to find some,” retorted the lad. At that moment Mr. Parker
+began breaking off bits of rock with a small geologist's hammer which he
+carried. The men with the guns looked at him.
+
+“So you think you'll find gold up here?” asked the one who had first
+spoken.
+
+“Is there any?” inquired Tom, trying to make his voice sound eager.
+
+“Nary a bit, strangers,” was the answer, and the two men laughed
+heartily. “Now, we don't want to seem harsh,” went on the man who seemed
+to be the spokesman, “but you'd better get away from here. This is
+private ground, and dangerous too--how'd you ever get up the trail--we
+heard it was destroyed.”
+
+“There is still a narrow path,” said Mr. Jenks. “We came up that--the
+lightning and landslide haven't left much of it, though.”
+
+Mr. Parker looked quickly up from the rocks at which he was tapping with
+his small hammer. “You have terrific lightning up here,” he said. “I am
+much interested in it, from a scientific standpoint. I predict that some
+day the entire mountain will be destroyed by a blast from the sky.”
+
+“I hope it won't be right away,” spoke one of the men. “Now I guess you
+folks had better be leaving while there's a path left to go down by.”
+
+“Might I ask,” broke in Mr. Parker, as calmly as though he was lecturing
+to a class of students, “might I ask if you have noticed any peculiar
+effect of the lightning up here on the summit of the mountain? Does it
+fuse and melt rocks, so to speak?”
+
+“What's that?” cried the spokesman, with a sudden flash of anger. The
+two men looked at each other.
+
+“I wanted to know, merely for scientific reasons, whether the lightning
+up here ever melted rocks?” repeated Mr. Jenks.
+
+“Well, whether it's for scientific reasons or for any other, I'm not
+going to answer you!” snapped the man. “It's none of your affair what
+the lightning does up here. Now you'd all better 'vamoose'--clear out!”
+
+“All right--we'll go,” said Tom, quickly, at the same time motioning to
+Mr. Jenks to agree with him. The eyes of the young inventor were
+roving about. He saw what looked like a second trail, leading down the
+mountain, from the far side of the cave. He was convinced now that there
+was another way to get to it. Possibly they might find it. At any rate
+nothing more could be done now. They must go back, for the cavern was
+too well guarded to attempt to enter it by force--at least just yet.
+
+“Yes, we'll go back,” assented Mr. Jenks.
+
+Mr. Parker was tapping away at the rocks. He looked toward the black
+mouth of the big cave. On what corresponded to the roof of it, some
+distance back from the entrance, he saw a slender metal rod sticking up
+into the air.
+
+“May I ask if that's a lightning rod?” he inquired innocently. “If
+it is, I should like to ask about its action in a mountain that is so
+impregnated with iron ore.
+
+“You may ask until you get tired!” cried the spokesman, again showing
+unreasoning anger, “but you'll get no answer from us. Now get away from
+here before we do something desperate. You're on private ground and
+you're not wanted. Clear out while you have the chance.”
+
+There was no help for it. Slowly our friends turned and began to go
+down the dangerous trail. They were soon out of sight of the two men who
+stood before the cave, with their guns ready, but neither Tom nor any of
+his companions spoke for some time.
+
+When they had rounded one of the most dangerous turns the young inventor
+sat down to rest, an example followed by the others.
+
+“Well,” asked Tom, “do you think those are some of the diamond makers,
+Mr. Jenks?”
+
+“I certainly do, though I never saw those two men before. If I could
+once get inside the cave, I could tell whether or not it was the one
+where I was practically held a prisoner. But I'm sure it is. I know some
+of the men used to go off every day with guns, and not come back until
+night. I have no doubt they were on guard, just as these two are. And,
+also, I think I heard them speak of a second entrance to the cavern. The
+one we just saw may not be the main one, through which I was taken.”
+
+“I believe we are on the right track,” ventured Mr. Damon, “but we will
+either have to go up there after dark, which will be risky, on account
+of the narrow trail, or else we will have to find some other path.”
+
+“The last would be better,” spoke Tom.
+
+“That rod of metal sticking up on top of the cave interested me,” said
+the scientist. “Did you hear anything of that when you were here before,
+Mr. Jenks?”
+
+“No. Probably that is only a lightning rod, or it may be a staff for a
+signal flag. But what surprises me is that those men didn't suspect
+that we were seeking to discover their secret. They took us for ordinary
+prospectors.”
+
+“So much the better,” remarked Tom. “We have a chance now of getting
+inside that cave. But we will have to go back to camp, and make other
+plans. And we must hurry, or it will be dark before we get there.”
+
+They hastened their steps, pausing only briefly to eat some of the lunch
+they had brought along, and to drink from a spring that bubbled from the
+side of the mountain. It was getting dusk when they got back to their
+tent. They found nothing disturbed.
+
+“I wonder if we'll see that phantom again to-night?” ventured Tom, as
+they were sitting about the campfire a little later.
+
+“Probably not,” remarked Mr. Jenks. “I don't believe the ghost will
+venture down the dangerous trail after dark, and the gang may think
+that the warning given us by the two men on guard at the cave will be
+sufficient. But if we don't leave here by to-morrow I think we will have
+another visit from the thing in white.”
+
+It was about an hour after this when Tom was collecting some wood in a
+pile nearer the fire, so as to have it ready to throw on, in case there
+was any alarm in the night, that he happened to look up toward the
+summit of the mountain. A slight noise, as of loose stones rolling down,
+attracted his attention, and, at first, he feared lest another landslide
+was beginning, but a moment later he saw what caused it.
+
+There, advancing down the steep and dangerous trail was the figure
+in white--the phantom. Instantly a daring plan came into Tom's head.
+Dropping the wood softly, he moved back out of the glare of the fire.
+
+“Mr. Jenks!” he called in a whisper.
+
+The diamond man, who was behind the tent, came toward Tom.
+
+“What is it?” he asked. Then, as he saw the ghostly visitor, he added:
+“Oh--the phantom again! What's it up to?”
+
+“The same thing,” replied Tom, “but it won't do it long, if my plan
+succeeds.”
+
+“What plan is that, Tom?”
+
+“I'm going to try to capture that--that man--or whatever it is. Will you
+help?”
+
+“Surely!”
+
+“Then let's work around behind it, while Mr. Damon and Mr. Parker come
+up from in front. We'll solve this part of the mystery, anyhow, if it's
+possible!”
+
+The two other men were soon told of the plan. Meanwhile the thing in
+white had advanced slowly, until within a few hundred feet of the camp.
+They could see now that it was no shaft of light, but some white body,
+shaped like a tall, thin man, draped in a white garment. The long arms
+waved to and fro. There was no semblance of a head.
+
+“You and Mr. Parker go right toward it, slowly, Mr. Damon,” advised
+Tom. “Mr. Jenks and I will make a circle, and get in back. Then, if it's
+anything alive we'll have it.”
+
+The “ghost” continued to advance. Tom and the diamond man stole off to
+one side, their buckskin moccasins making no sound. Mr. Damon and the
+scientist went boldly forward.
+
+This movement appeared to disconcert the spirit. It halted, waved the
+arms with greater vigor than before, and seemed to indicate to the
+adventurers that it was dangerous to advance. But Mr. Damon and Mr.
+Parker kept on. They wanted to give Tom and Mr. Jenks time enough to
+make the circuit.
+
+Suddenly the stillness of the night was broken by a low whistle. It was
+Tom's signal that he and Mr. Jenks were ready.
+
+“Come on! Run!” cried Mr. Damon.
+
+The scientist and the eccentric man leaped forward.
+
+The “ghost” heard the whistle, and heard the spoken words. The thing in
+white hesitated a moment, and then raised one arm. There was a flash of
+fire, and a loud report.
+
+“He's firing in the air!” cried Tom. “Come on, we have him now!”
+
+Undaunted by the display of firearms, Mr. Damon and Mr. Parker kept on.
+They could hear Tom and Mr. Jenks running up in back of the figure.
+The latter also heard this, and suddenly turned. Caught between the two
+forces of our friends, the “ghost” was at a loss what to do.
+
+The next instant Tom, who had distanced Mr. Jenks, made a flying tackle
+for the figure in white, and caught it around the legs. Very substantial
+legs they were, too, Tom felt--the legs of a man.
+
+“Wow!” yelled the “ghost,” as he went down in a heap, the revolver
+falling from his hand.
+
+“Come on!” cried Tom. “I have him!”
+
+His friends rushed to his aid. There was a confused mass of dark bodies,
+arms and legs mingled with something tall and thin, all in white.
+Suddenly the moon came from behind a cloud and they could see what they
+had captured--for captured the phantom was.
+
+It proved to be a rather small man, who wore upon his shoulders a
+framework of wood, over which some white cloth was draped. It had fallen
+off him when Tom made that tackle.
+
+“Well,” remarked the young inventor, as he sat on the struggling man's
+chest. “I guess we've got you.”
+
+“I rather guess you have, stranger,” was the cool reply.
+
+
+
+
+CHAPTER XVIII--BILL RENSHAW WILL HELP
+
+
+They were all panting from the exertion of the run up the mountain and
+the contest with the phantom--a phantom no longer--though, truth to
+tell, the struggle was not nearly so fierce as Tom had expected. He
+thought the “ghost” would put up a stiff fight.
+
+“Got any ropes to tie him with?” asked Mr. Damon, who was helping Tom
+hold the man down.
+
+“Ropes? You aren't going to tie me up are you, strangers?” asked the
+captive.
+
+“That's what we are!” exclaimed Mr. Jenks. “We've had trouble enough in
+this matter, and if I've got one of the gang, perhaps I can get some of
+the others, and have my rights. So tie him up, Tom, and we'll take him
+to camp.
+
+“Oh, you needn't go to all that trouble, strangers,” went on the man,
+calmly. “If one of you will get off my chest, and the other gentleman
+ease up on my stomach a bit, I'll walk wherever you want me, and not
+make any trouble. I haven't got a gun.”
+
+“Bless my gloves! But you're a cool one,” commented Mr. Damon, as he
+complied with the man's request, and got up from his stomach. “But look
+out for him, Tom. He had a gun, for he fired it in the air.”
+
+“He hasn't it now,” answered the young inventor. “I knocked it from his
+hand when I leaped for him.”
+
+“That's what you did,” assented the man, as he got up, while Tom kept a
+tight hold of him, as did Mr. Jenks. “What kind of a grizzly bear hug do
+you call that, anyhow, that you gave me?”
+
+“That was a football tackle,” explained Tom.
+
+“I allers heard that was a dangerous game!” remarked the former phantom
+simply. “Well, now you've got me, what are you going to do with me?”
+
+“Take you where we can have a good look at you,” replied Mr. Jenks, as
+he kicked aside the wooden framework, and the sheet which had made the
+“ghost” appear so tall. “So this is how you worked it; eh?”
+
+“Yep. That was the 'haunt' stranger. I made it myself, and it worked all
+right until you folks come along. I rather suspicioned from the first,
+when I played the trick over on 'tother side of the mountain, that you
+wouldn't be so easy to fool as most prospectors are.”
+
+“Oh, so you're the only ghost then?” asked Tom.
+
+“I'm the only one.”
+
+By this time they had reached the camp. Tom threw some light logs on the
+fire, which blazed up brightly. As the flames illuminated the face of
+their captive, Mr. Jenks looked at him, and cried out:
+
+“Why it's Bill Renshaw!”
+
+“That's me,” admitted the man who had played the part of the phantom,
+“and thunder-turtles! if it ain't Mr. Jenks who was once in the diamond
+cave with us. Whatever happened to you? I never heard. The others said
+you got tired and went away.”
+
+“They took me away--defrauded me of my rights!” declared Mr. Jenks,
+bitterly. “But I'll get them back! To think of Bill Renshaw playing the
+part of a ghost!”
+
+“They made me do it,” went on the man, somewhat dejectedly. “I wanted to
+be at work in the cave, but they wouldn't let me.”
+
+“Is this man one of the diamond makers?” asked Tom, in great surprise.
+
+“He is--one of the helpers, though I don't believe he knows the secret
+of making the gems,” explained Mr. Jenks. “He was one of the men in the
+cave when I was there before, and he and I struck up quite a friendship;
+didn't we, Renshaw?”
+
+“That's what, and there ain't no reason why we can't be friends now;
+that is unless you hold a grudge against me for firing at you. But I
+only shot in the air, to scare you away. Them's my instructions. I'm
+supposed to be on guard, and scare away strangers. I'm tired of the
+work, too, for I don't get my share, and those other fellows, in the
+cave, get all the money from the diamonds.”
+
+Tom Swift uttered an exclamation. A sudden plan had come to him. Quickly
+he whispered to Mr. Jenks:
+
+“Make a friend of this man if possible. He evidently is dissatisfied.
+Offer him a sum to show us another way into the cave, and we may yet
+discover the secret of the diamond makers.”
+
+“I will,” declared Mr. Jenks, quietly. Then, turning to Renshaw, he
+added:
+
+“Bill, come over here. I want to have a talk with you. Perhaps it will
+be to our mutual advantage.”
+
+He led the former phantom to one side, and for some time conversed
+earnestly with him. Mr. Jenks told the story of how he had been deceived
+by Folwell and the others who were at the head of the gang of diamond
+makers. The rich man related how they had taken his money, and, after
+promising to disclose the secret process to him, had broken faith, and
+had drugged him, afterward taking him out of the cave.
+
+“I want only my rights, and that for which I paid,” concluded Mr. Jenks.
+“Now, I gather that these men haven't treated you altogether fairly,
+Bill.”
+
+“Indeed they haven't. I helped 'em to the best of my ability, and all
+I get out of it is to stay out on this lonely side of the mountain,
+and play ghost. They owe me money, too, and they won't pay me, either,
+though they have lots, for they sold some diamonds lately.”
+
+“Then they are still making diamonds?” asked Mr. Jenks, eagerly. “Have
+you seen them? Do you know the secret?”
+
+“No, I don't know it, for they won't let me in on it. I'm always sent
+out of the cave just before they make the gems. But I know they've made
+some lately, and have sold 'em. I want my share.”
+
+“Look here!” exclaimed Mr. Jenks, quickly, wishing to strike while the
+iron was hot. “I'll make you a proposition. Show us how to get into that
+cave, unknown to the diamond makers, and I'll pay you twice what they
+agreed to. Is it a bargain?”
+
+Bill Renshaw considered a moment. Then he thrust out his hand, clasped
+that of Mr. Jenks, and exclaimed:
+
+“It is. I'll take you into the cave by an entrance that's seldom used.
+There are four ways to get in. The one where the two men drove you back
+is the rear one. The front one is on the other side of the mountain, but
+it's so well concealed that you'd never find it. But I can take you to
+one where you can get in, and those fellows will never know it. And,
+what's more, I'll help you if it comes to a fight!”
+
+“Good!” exclaimed Mr. Jenks. “I think we'll discover the secret of the
+diamond makers this time,” and he went to tell the others of the success
+of his talk. Bill Renshaw had been converted from an enemy into a
+friend, and the former phantom was now ready to lead Tom and the others
+into the secret cave.
+
+“We'll start in the morning,” decided Mr. Jenks, who, after many
+disappointments, at last saw success ahead of him.
+
+
+
+
+CHAPTER XIX--IN THE SECRET CAVE
+
+
+Tom Swift was up at break of day, and the others were not far behind
+him.
+
+“Now for the secret cave!” cried the young inventor as he gazed up
+the mountain, in the interior of which the mysterious band of men were
+making the diamonds.
+
+“Have you made any plans, Bill?” asked Mr. Jenks of the former phantom,
+who had cast his lot in with the adventurers. “What will be the best
+course for us to follow?”
+
+“You just leave it to me, Mr. Jenks,” was the answer. “I'll get you into
+the cave, and those fellows, who, I believe, are trying to do me out of
+my rights, as they did you out of yours, will never know a thing about
+it.”
+
+“Bless my finger-nails!” cried Mr. Damon. “That will be great! We can
+get in the cave, and watch them make the diamonds at our leisure.”
+
+“They don't make them every day,” explained Renshaw. “It seems they
+have to wait for certain occasions. Mostly they make the diamonds when
+there's a big storm.”
+
+“A big storm,” asked the scientist with a sudden show of interest.
+“Do you mean one of those electrical storms, such as we had the other
+night?”
+
+“That's it, Mr. Parker, though why they wait until there's a storm is
+more than I can tell.”
+
+“Perhaps they know that on such occasions no one will venture up the
+mountain,” spoke Mr. Damon.
+
+“No, it isn't that,” declared the scientist. “I think I am on the
+track of a great scientific discovery, and I will soon be able to make
+observations that will confirm it.”
+
+“Well, I'm going to make an observation right now,” said Tom, with a
+laugh. “I'm going to see what there is for breakfast.”
+
+“And that reminds me,” came from Mr. Jenks, “shall we move our camp,
+Bill, and take the tent with us to the cave?”
+
+“I hardly think so,” was the answer. “I think the best plan would be to
+conceal the tent somewhere around here, in case you might need it again.
+You can also store what food you have left.”
+
+“But, bless my appetite, we don't want to starve in that diamond cave!”
+ objected Mr. Damon.
+
+“I'll see that you don't,” declared Bill Renshaw. “I'll take you in
+there, unbeknownst to those fellows, and I'll provide you with plenty
+of food and water. You see the cave is so big that there are some parts
+they never visit.”
+
+“And we can stay in one of those parts, and eat?” asked Tom.
+
+“Sure,” answered Bill.
+
+“And watch the diamond makers at work?” asked Mr. Jenks.
+
+“That's it,” replied the former phantom.
+
+“Then the sooner we get started the better,” remarked Mr. Damon. Mr.
+Parker said nothing. He appeared to be thinking deeply, and was tapping
+at some rocks with his little hammer.
+
+The advice of Bill Renshaw was followed, and the tent, and what food
+remained, was concealed in the bushes, with rocks piled over to keep
+away prowling animals. Then they started for the secret cave.
+
+The man who played the part of a ghost picked up the framework and white
+cloth that had formed his disguise.
+
+“I'll still have to use this,” he explained, “for I don't want those
+fellows to know that I'm helping you. I'll continue to play the spirit
+of the mountain, but there won't be much need of it. I don't think any
+more people will come prospecting out here.”
+
+“Have you heard of the arrival of Farley Munson?” asked Tom, as he
+related the facts about the stowaway.
+
+“He hadn't arrived up to a day or so ago,” answered Bill. “I guess he's
+still traveling. Farley is one of the heads of the gang,” he added, “and
+a dangerous man.”
+
+As Bill led the way toward the cave, taking a route that the adventurers
+had never suspected led to it, he explained that the cavern was a large
+one, capable of holding an army.
+
+“But there's only a small part of it used by the diamond makers,” he
+added. “They work in a small recess, near the summit of the mountain.
+The little cave, where I'm going to take you, opens off from it by a
+long passage. And, except that you'll be pretty much in the dark, you'll
+be quite comfortable. There are tables, chairs, and some bunks in the
+place. I can get you some lights, and plenty of food.”
+
+“But, if you are seen taking away food, won't the others suspect
+something?” asked Tom.
+
+“I do pretty much as I please,” said Bill. “I go and come when I like.
+All I'm supposed to do is to watch my two sides of the mountain, play
+the ghost, and give warning when any one is coming. Sometimes I leave
+black and white messages, like the one I put on your tent. Those fellows
+fix 'em up for me. I've told 'em about you, though I didn't know who you
+were, and they think you have gone, for the two men on guard at the rear
+entrance so reported. Sometimes I stay out on the mountain for a couple
+of days at a time, when the weather's good, and don't go back to the
+cave. Those times I take food with me, and so if they see me making off
+with some supplies they'll think I'm going to camp out.”
+
+“It doesn't look as though we'd ever get into a cave near the top of the
+mountain, going this way,” said Tom, as they marched along. “We're going
+down, instead of up.”
+
+“That's the secret of this trail,” explained Bill. “We go down in a
+sort of valley, and then go up a pretty stiff place, and then we're on
+a direct trail to the entrance I told you about. It's a steep road to
+climb, but I guess we can manage it.”
+
+And a hard climb the adventurers did find it. The road was almost as bad
+as the one along the edge of the chasm, but they managed to negotiate
+it, and finally found themselves on a fairly good trail.
+
+“We'll soon be there,” Bill assured them. “After you get in the little
+cave, where I'm going to hide you, I'll have to leave you for a spell,
+until I get my ghost rigging fixed up again. But I'll see that you have
+plenty of food and drink.”
+
+A little later their guide came to a sudden halt, and peered around
+anxiously.
+
+“What's the matter?” asked Tom.
+
+“I was just looking to see if any of the men were about,” he answered.
+“But I guess not--it looks all right. The entrance is right here.”
+
+They were on a side of the mountain, near the summit. Below stretched a
+magnificent scene. A great valley lay at their feet, and they could look
+off to many distant peaks. The main trail to Leadville, and the one to
+the settlement of Indian Ridge, was in sight.
+
+Suddenly Tom, who had been using a small but powerful telescope, uttered
+an exclamation, and focussed the instrument on a speck that seemed
+moving along on the trail below.
+
+“A man--coming up the mountain,” cried Tom. “And--it can't be--yet it
+is--it's Farley Munson--the stowaway!” he cried. “He's coming here!”
+
+“Let me look!” begged Mr. Jenks, taking the glass from Tom. An instant
+later the diamond man exclaimed: “Yes, it's Munson!”
+
+“Then in here with you--quick!” cried Renshaw. “He can't see us yet, and
+we'll be out of sight in another minute.”
+
+The former spirit pulled aside some thick bushes, and pointed to a hole
+which was disclosed.
+
+“The entrance to the secret cave,” he announced. “Slip in all of you.”
+
+Tom, after another glance at the man toiling his way up the mountain,
+entered the cavern. He was followed by the others. Bill was the last to
+enter, and he replaced the bushes over the entrance.
+
+“At last!” exclaimed Mr. Jenks, as he gazed up at the roof of the
+dimly-lighted vault in which they found themselves.
+
+“Yes, we're in the diamond makers' secret cave,” added Tom. “Now to
+catch them at work!”
+
+“Come on,” advised Bill, in a low tone, “We're not safe yet,” and he
+produced a lantern from some hidden recess, lighted the wick, and led
+the way. As the others followed they were aware of a subdued noise in
+the great cavern.
+
+
+
+
+CHAPTER XX--MAKING THE DIAMONDS
+
+
+“What's that noise?” asked Tom, as their guide flashed the lantern to
+show them the way.
+
+“That's the men getting ready to make diamonds, I guess,” was the
+answer. “You see it takes quite a while to get the stuff ready. I don't
+know what they use--they never tell me any of their secrets.”
+
+“Oh, I know the ingredients well enough,” said Mr. Jenks, “but I
+don't know the secret of how they apply the terrific heat and pressure
+necessary to fuse the materials into diamonds.”
+
+“Well, you'll soon know,” declared Bill Renshaw. “Of course it isn't
+always successful. I've known 'em to try half a dozen times before they
+got any diamonds big enough to satisfy 'em. They gave me some of the
+small ones when I asked for my wages.
+
+“How did you come to get in with these men?” asked Tom, curious to
+understand how a person seemingly as honest as Renshaw appeared to be
+had cast his lot in with the men who had broken faith with Mr. Jenks.
+
+“Oh, I've lived around these parts all my life,” was the answer. “I knew
+of this cave before these diamond fellers came to it. In fact, I
+showed it to 'em. It was several years ago that a party of men who were
+prospecting around here came to me and asked if I knew of a small cave
+near the top of a high mountain, where lightning storms were frequent.
+I told them about Phantom Mountain, as it was called then, and also of
+this cave. If there's any place where they have worse lightning storms
+than here, I'd like to know it. They scare me, sometimes, like the night
+when that landslide happened, and I'm sort of used to 'em.
+
+“Well, I took these men to the cave, and they hired me as a sort of
+lookout. Then they began their work, and at first I didn't know what
+they were up to, but finally I caught on. Then Mr. Jenks came, and
+disappeared mysteriously, though then I didn't know that they had played
+a trick on him. I was outside most of the time, pretending I was the
+ghost. So that's how I came to get in with 'em, and I wish I was out.”
+
+“You soon will be, I think,” declared Mr. Jenks. “But won't our talking
+be heard by the men?”
+
+“No danger. There is a thick wall between this part of the cave, and the
+part where they live and work. I'll soon have you well hid, and then you
+wait until I come back.”
+
+“What about Munson?” asked Tom. “He is evidently on his way here to tell
+his confederates about us.”
+
+“He won't know what has happened to us,” said Mr. Jenks, “and he won't
+see anything of us. I guess we're safe enough.”
+
+Through the dark passage they followed Bill Renshaw until he came to a
+halt in a place that suddenly widened and broadened into a good-sized
+cave.
+
+“Here's your stopping place,” said the former ghost. “Now if you follow
+that passage, off to the left,” and he pointed to it, “you'll come
+to the larger part of the cave where the diamond makers are. But go
+cautiously, and don't make any noise. I won't be responsible for what
+happens.”
+
+“We'll take all the risk,” interrupted Tom.
+
+“All right. Now there's a couple of lanterns around here. I'll light
+them, and leave you for a while until I can get some grub. I'll be back
+as soon as I can.”
+
+He glided away, after lighting two lanterns, by the gleams of which
+the adventurers could see that they were in a vaulted cavern that had
+evidently been fitted up as a living apartment. The sides, roof and
+floor were of stone. It was clean, and the air was fresh. There were
+some chairs, a table, and several cots, with pieces of bagging for
+bedding, though it was warm in the place.
+
+“I guess we can stay here until we discover the secret,” spoke Tom.
+
+“Bless my watch! We can if we have something to eat,” came from Mr.
+Damon, with something like a sigh. “I'm hungry!”
+
+“And I want to make some observations,” said Mr. Parker. “From what I
+have seen of this mountain, I would not be surprised if this cave was
+to be suddenly destroyed by a landslide or a lightning bolt. I will make
+some further investigations.”
+
+“Well, if it's going to cause you to make such gloomy prophecies as
+that, I'd just as soon you wouldn't look any further,” spoke Tom, in
+a low voice. But Mr. Parker, taking one of the lanterns, set about
+examining the rock of which the cave consisted.
+
+In a short time Bill Renshaw returned with enough food to last for two
+days. He said he was going out on the mountain once more to act the part
+of a lookout, and would visit the adventurers again the next day.
+
+“In the meanwhile you can do just as you please,” he said. “Nobody is
+likely to disturb you here, and you can sneak up and take a look at the
+men in the other cave whenever you're ready. Only be careful--that's all
+I've got to say. They're desperate men.”
+
+It was not very pleasant, eating in the gloomy cavern, but they made the
+best of it. They cooked on a small oil-stove they found in the place,
+and after some hot coffee they felt much better.
+
+“Well,” remarked Tom, after a while, “shall we take a chance, and go
+look at the men at work?”
+
+“I think so,” answered Mr. Jenks. “The sooner we discover this mystery,
+the better. Then we can go back home.”
+
+“And recover my airship,” added Tom, who was a bit uneasy regarding the
+safety of the Red Cloud.
+
+“Then, bless my finger-rings! let's go and see if we can find the big
+cave your friend the ghost told us of,” suggested Mr. Damon.
+
+Cautiously they made their way along the passage Bill had pointed out.
+As they went forward the subdued noise became louder, and finally they
+could feel the vibration of machinery.
+
+“This is the place,” whispered Mr. Jenks. “That sound we hear is one of
+the mixing machines, for grinding the materials--carbon and the other
+substances--which go to make up the diamonds. I remember hearing that
+when I was in the cave before.”
+
+“Then we must be near the place,” observed Tom.
+
+“Yes, but I didn't have much chance to look around when I was here
+before. They wouldn't let me. I never even knew of the small cave Bill
+took us to.”
+
+“Well, if we're close to it, we'd better go cautiously, and not talk any
+more than we're obliged to,” suggested Mr. Parker, and they agreed that
+this was good advice.
+
+They walked on softly. Suddenly Tom, who was in the lead, saw a gleam of
+light.
+
+“We're here,” he whispered. “I'll put out our lantern, now,” which he
+did. Then, stealing forward he and the others beheld a curious sight.
+The tunnel they were in ended at a small hole which opened into a large
+cavern, and, fortunately, this opening was concealed from the view of
+those in the main place.
+
+“The diamond makers!” whispered Tom, hoarsely, pointing to several men
+grouped about a number of strange machines.
+
+“Yes--the very place where I was,” answered Mr. Jenks, “and there is the
+apparatus--the steel box--from which the diamonds are taken--now to see
+how they make them.”
+
+Fascinated, the adventurers looked into the cave. The men there were
+unaware of the presence of our friends, and were busily engaged. Some
+attended to the grinding machine, the roar and clatter of which made
+it possible for Tom and the others to talk and move about without being
+overheard. Into this machine certain ingredients were put, and they were
+then pulverized, and taken out in powdery form.
+
+The power to run the mixing machine was a gasoline motor, which
+chug-chugged away in one corner of the cave.
+
+As the powder was taken out, other men fashioned it into small balls,
+which were put on pan, and into a sort of oven, that was heated by a
+gasoline stove.
+
+“Is that how they make the diamonds?” asked Mr. Damon.
+
+“That is evidently the first step,” said Mr. Jenks. “Those balls of
+powdered chemicals are partly baked, and then they are put into the
+steel box. In some way terrific heat and pressure are applied, and the
+diamonds are made. But how the heat and pressure are obtained is what we
+have yet to learn.”
+
+He paused to watch the men at work. They were all busy, some attending
+to the machines, and others coming and going in and out of the cave. In
+one part a man was apparently getting ready a meal.
+
+Suddenly there rushed into the cave a man who seemed much excited.
+
+“Are you nearly ready with that stuff?” he cried. “There's a good storm
+gathering on the mountain!”
+
+“Yes, we'll be ready in half an hour,” answered one of the men at the
+mixing machine.
+
+“Good. It will be flashing lightning bolts then, and we can see what
+luck we have. The last batch was a failure.” The man hurried out again.
+Mr. Parker touched Tom and Mr. Jenks on their shoulders.
+
+“What is it?” asked Tom.
+
+“I know the secret of making the diamonds,” said the scientist.
+
+“What?” cried Mr. Jenks.
+
+“It is by the awful power of the lightning bolts!” whispered Mr. Parker.
+“Everything is explained now--the reason why they make diamonds in this
+lonely place, near the top of the mountain. They need a place where the
+lightning is powerful. I can understand it now--I suspected it before.
+They make diamonds by lightning!”
+
+“Are you sure?” cried Mr. Jenks.
+
+“Positive.”
+
+“I agree with you,” said Tom Swift. “I was just getting on that track
+myself, when I saw the electric wires running to the steel box. That
+explains the upright rod on the top of the mountain. The man says
+a storm is coming--very well; we'll stay here and watch them make
+diamonds!”
+
+As he spoke there came the mutter of thunder, and the mountain vibrated
+slightly. The men in the cave redoubled their activity. Tom and his
+friends felt that the secret process they had so long sought was about
+to be demonstrated before their eyes.
+
+
+
+CHAPTER XXI--FLASHING GEMS
+
+
+Eagerly the adventurers looked through the opening at the end of the
+passage into the larger cave. The men opened the small oven in which the
+balls of white chemicals and carbon mixed, had been baked, and a pile of
+things, that looked like irregularly-shaped marbles, were placed in the
+steel box.
+
+This box, which was about the size of a trunk, was of massive metal. It
+was placed in a recess in the solid rock, and all about were layers of
+asbestos and other substances that were nonconductors of heat.
+
+“That box becomes red hot,” exclaimed Mr. Jenks, in a whisper. “When
+things are in readiness, that lever is pulled and the diamonds are
+made. I pulled it once, but I did not then know the process involved. I
+supposed that the lightning had nothing to do with making the diamonds.”
+
+“It has--a most important part,” said Mr. Parker. The hidden adventurers
+could talk in perfect safety now, for the men in the large cave were too
+excited to pay much attention to them. The muttering of the thunder
+grew louder, and at times a particularly loud crash told that a bolt had
+struck somewhere in the vicinity of the cave.
+
+“But, bless my watch-charm!” exclaimed Mr. Damon, “I didn't know
+lightning made diamonds.”
+
+“It does not--always,” went on the scientist. “But great heat and
+pressure are necessary to create the gems. In nature this was probably
+obtained by prehistoric volcanic fires, and by the terrific pressure of
+immense rocks. It is possible to make diamonds in the laboratory of the
+chemist, but they are so minute as to be practically valueless.
+
+“However, these men seem to have hit upon a new plan. They utilize the
+terrific heat of lightning, and the pressure which is instantaneously
+obtained when the bolt strikes. I am anxious to see how it is done.
+Look, I think they are getting ready to make the gems.”
+
+Indeed there seemed to be an air of expectancy among the diamond makers.
+The mixing machine had now been stopped, and, as it was more quiet
+in the cave, our friends, in their hiding-place, had to speak in mere
+whispers. All the men were now gathered about the great steel box.
+
+This receptacle had been closed by a solid metal door, which was screwed
+and clamped tight. Then one of the men examined a number of heavily
+insulated electric wires that extended from the box off into the
+darkness where Tom and his companions could not discern them.
+
+“That's Folwell--the man I befriended, and who got me into this game,”
+ whispered Mr. Jenks. “He was also one of the first to turn against me. I
+think he's one of the leaders.”
+
+Folwell came back, after having gone into a dark part of the cave. He
+went over to an electrical switch on one of the stone walls.
+
+“It's almost time,” Tom heard him say to his confederates. “The storm is
+coming up rapidly.”
+
+“Will it be severe enough?” asked one of the helpers. “We had all our
+work for nothing last time. The flashes weren't heavy enough.”
+
+“These will be,” asserted Folwell. “The indicator shows nearly a million
+volts now, and it's increasing.”
+
+“A million volts!” exclaimed Tom. “I hope it doesn't strike anywhere
+around here.”
+
+“Oh, it will probably be harmlessly conducted down on the heavy wires,”
+ said Mr. Parker. “We are in no danger, at present, though ultimately I
+expect to see the whole mountain shattered by a lightning bolt.”
+
+“Cheerful prospect,” murmured Tom.
+
+There was a terrific crash outside. The rocky floor of the cave
+trembled.
+
+“Here she comes!” cried Folwell. “Get back, everybody! I'm going to
+throw over the switch now!”
+
+The men retreated well away from the steel box. Folwell threw over the
+lever--the same one Mr. Jenks remembered pulling. Then the man ran
+to the electric switch on the wall, and snapped that into place,
+establishing a connection.
+
+There was a moment's pause, as Folwell ran to join the others in their
+place of safety. Then from without there came a most nerve-racking and
+terrifying crash. It seemed as if the very mountain would be rent into
+fragments.
+
+Watching with eager eyes, the adventurers saw sparks flash from the
+steel box. Instantly it became red hot, and then glowed white and
+incandescent. It was almost at the melting point.
+
+Then came comparative quiet, as the echoes of the thunder died away amid
+the mountain peaks.
+
+“I guess that did the trick!” cried Folwell. “It was a terrific crash
+all right!”
+
+He and the others ran forward. The steel box was now a cherry red,
+for it was cooling. Folwell threw back the lever, and another man
+disconnected the switch. There was a period of waiting until the box was
+cool enough to open. Then the heavy door was swung back.
+
+With a long iron rod Folwell drew something from the retort. It was the
+tray which had held the white balls. But they were white no longer, for
+they had been turned into diamonds. From their hiding-place Tom and the
+others could see the flashing gems, for, in spite of the fact that the
+diamonds were uncut, some of them sparkled most brilliantly, due to the
+peculiar manner in which they were made.
+
+“We have the secret of the diamonds!” whispered Mr. Jenks. “There must
+be a quart of the gems there!”
+
+The men gathered about Folwell, uttering exclamations of delight. The
+diamonds were too hot to handle yet.
+
+“That's going some!” exclaimed the chief of the diamond makers. “We have
+a small fortune here.”
+
+The was a sudden commotion at one end of the cave. A man rushed in. At
+the sight of him Tom stared and uttered an exclamation.
+
+“Munson--the stowaway!” he whispered.
+
+“Hello!” cried Folwell, as he saw his confederate. “I thought you were
+East, keeping Jenks away from here.”
+
+“He got the best of me!” cried Munson, “he and that Tom Swift! I stowed
+away on their airship, but they found me out by a wireless message,
+and marooned me in the woods. I've been trying to get here ever since!
+Didn't you get my messages of warning?”
+
+“No--what warnings?” cried Folwell.
+
+“About Jenks, Tom Swift and the others. They're here--they must be on
+Phantom Mountain now. In fact, I shouldn't be surprised if they were in
+this cave. I traced them to their camp, but they're gone. They may be
+among us now--in some of the secret recesses!”
+
+For an instant Folwell stared at the bearer of these tidings. Then he
+cried out:
+
+“Scatter men, and find these fellows! We must get them before they
+discover our secret!”
+
+“It's too late--we know it!” exulted Tom Swift. Then he whispered to
+the others to hurry to the part of the cave where Bill Renshaw had first
+hidden them.
+
+
+
+
+CHAPTER XXII--PRISONERS
+
+
+“Do you think there is any danger of them finding us?” asked Mr. Damon,
+as he hurried along beside Tom.
+
+“I'm afraid so,” was the answer. “I've been worried ever since we saw
+Munson heading this way. But we couldn't do any differently.”
+
+“Perhaps Bill Renshaw may be able to conceal us,” suggested Mr. Jenks.
+“Very likely he knows that Munson is on hand. Perhaps we will be safe
+for a while. I want to make a few more observations as to how they
+manufacture the diamonds, and then, with what I already know, I'll have
+the secret.”
+
+“And I'd like to make some scientific tests of the sides and bottom
+rocks of the cave,” spoke Mr. Parker. “I think it will bear out my
+theory that the mountain will soon be destroyed.”
+
+“Well, you were right about Earthquake Island, and you may be right
+about this mountain,” said Tom, “but if it is going to be annihilated I
+hope we get far enough away from it.”
+
+“We can keep our presence here a secret for a few more days, I think
+that will be long enough,” proceeded Mr. Jenks. “Then we will leave.”
+
+“And, in the meanwhile, they'll be searching for us,” objected Mr.
+Damon. “I wish that ghost-chap would come back and tell us what to do.
+Bless my liver-pin, but we are going to be in considerable danger, I'm
+afraid! Those men may capture us, and decide to make diamond dust from
+us.”
+
+“Come on--hurry to the little cave,” urged Tom. “Then we'll get ready to
+defend ourselves.”
+
+“The main cave is a large one,” said Mr. Jenks, “and there are many
+hiding places in it. In fact, it is so large that it will take those
+fellows several days to complete a circuit of it. By that time Bill
+Renshaw may come back, and take us to some place in which they have
+already searched for us. Then we'll be comparatively safe.”
+
+This thought was some consolation to them, as they made their way
+through the dark passage, dimly illuminated by the lantern they had
+rekindled, to the place where Bill had hidden them. They found things
+as they had left them, and proceeded to get a meal, though Tom said it
+would be best not to cook anything, or even to make coffee, for fear the
+odors would enable the searchers to trail them.
+
+So they ate cold food, glad to get that. Silently they sat about the
+dimly-lighted cavern, and discussed the situation. True they might even
+now retreat, going out of the entrance Bill had showed them, and so
+escape. But Mr. Jenks felt that his mission was not completed yet, and
+they all agreed to stay with him.
+
+“For there are several points about making diamonds that are not
+quite clear to me,” he said. “I need to know how that steel box is
+constructed, how the electrical switches are arranged, what kind of
+lightning rods they use, and how they regulate the pressure. The other
+things, and how to mix the ingredients, I already know.”
+
+“Then we'll do our best to help you,” promised Tom. “But now I think we
+had better see what sort of a defense we can put up. We have our guns
+and revolvers, and with these chairs and tables we can build a sort of
+barricade behind which we can take refuge if those fellows do discover
+our hiding place.”
+
+This was conceded to be a good idea, and soon a rude sort of fort was
+made, behind which the adventurers could take their stand and fight, if
+necessary, though they hoped this would not come to pass.
+
+They remained quietly in the cave the remainder of that day, and, when
+it was night, as they could tell by their timepieces--there was no
+daylight--they divided the hours into watches, taking turns standing
+guard.
+
+Morning, at least in point of time, came without any disturbance, and
+they made a cold breakfast. They hoped that Bill Renshaw would come, but
+he did not appear.
+
+After sitting in the dark cave until afternoon, Tom said:
+
+“I think we might as well go and take another observation of the big
+cave. We can tell what the men are doing, then, for they don't seem to
+have been near us. Maybe they have given up the search for us, and we
+can see them at work, and Mr. Jenks can gain what further knowledge he
+needs.”
+
+“That will be a good plan,” agreed the diamond man. “It's maddening to
+sit here, doing nothing.”
+
+“And it will be comparatively safe to go from here to our former post of
+observation,” added Tom, “for there doesn't seem to be any opening along
+the tunnel, into the larger cave, except the place where we were.”
+
+Accordingly they started off. Cautiously they looked through the opening
+into the apartment where they had seen the diamonds made.
+
+“There's not a soul here!” exclaimed Tom, in a whisper. The others
+looked. The place was deserted--the machinery silent. Mr. Jenks peered
+in for a moment, and then exclaimed:
+
+“I'm going in! Now's my chance to find out all that I wish to know! It
+may never come again, and then we can soon leave Phantom Mountain!”
+
+It was a daring plan, but it seemed to be the best one to follow. They
+were all tired of inactivity. Mr. Jenks managed to get through the
+opening, and dropped into the big cave. The others followed. Mr. Jenks
+hurried over to the steel box, and began an examination of it. Tom Swift
+was looking at the electrical switch. He saw how it was constructed. Mr.
+Damon and Mr. Parker were peering interestedly about.
+
+Suddenly the sound of voices was heard, and the echo of footsteps. Mr.
+Jenks started.
+
+“They're coming back!” he whispered hoarsely. “Run!”
+
+They all turned and sped toward their hiding place. But they were too
+late. An instant later Folwell, Munson and the other diamond makers
+confronted them. Our friends made a bold rush, but were caught before
+they could go ten feet.
+
+“We have them!” cried Munson. “They walked right into our hands!”
+
+It was true. Tom Swift and the others were the prisoners of the diamond
+makers.
+
+
+
+CHAPTER XXIII--BROKEN BONDS
+
+
+“Well,” remarked Tom Swift, in mournful tones, “this looks as if we were
+up against it; doesn't it?”
+
+“Bless my umbrella, it certainly does,” agreed Mr. Damon.
+
+“And it's all my fault,” said Mr. Jenks. “I shouldn't have gone into the
+big cave. I might have known those men would come back any time.”
+
+The above conversation took place as our friends lay securely bound in
+a small cave, or recess, opening from the larger cavern, where, about
+an hour before, they had been captured and made prisoners by the diamond
+makers. Despite their struggles they had been overpowered and bound,
+being carried to the cave, where they were laid in a row on some old
+bags.
+
+“It certainly is a most unpleasant situation, to say the least,”
+ observed Mr. Parker.
+
+“And all my fault,” repeated Mr. Jenks.
+
+“Oh, no it isn't,” declared Tom Swift, quickly. “We were just as ready
+to follow you into that cave as you were to go. No one could tell that
+the men would return so soon. It's nobody's fault. It's just our bad
+luck.”
+
+From where he lay, tied hand and foot, the young inventor could look
+out into the cave where he and the others had been caught. The diamond
+makers were busily engaged, apparently in getting ready to manufacture
+another batch of the precious stones. They paid little attention to
+their captives, save to warn them, when they had first been taken into
+the little cave, that it was useless to try to escape.
+
+“They needn't have told us that,” observed Tom, as he and the others
+were talking over their situation in low voices. “I don't believe any
+one could loosen these ropes.”
+
+“They certainly are pretty tight,” agreed Mr. Damon. “I've been tugging
+and straining at mine for the last half hour, and all I've succeeded in
+doing is to make the cords cut into my flesh.”
+
+“Better give it up,” advised Mr. Jenks.
+
+“We'll just have to wait.”
+
+“For what?” the scientist wanted to know.
+
+“To see what they'll do with us. They can't keep us here forever.
+They'll have to let us go some time.” Following their capture, Folwell
+and Munson, the latter the stowaway of the airship, had been in earnest
+conversation regarding our friends, but what conclusion they had reached
+the adventurers could only guess.
+
+“And we didn't have time to examine the diamond-making machinery close
+enough so that we could duplicate it if necessary,” complained Tom, a
+little later.
+
+“No,” agreed Mr. Jenks. “There are certain things about it that are not
+clear to me. Well, I don't believe I'll have another chance to inspect
+it. They'll take good care of that, though they seem to be getting ready
+to make more diamonds.”
+
+“Perhaps they're going to manufacture a big batch, and then leave this
+place,” suggested Mr. Damon. “They will probably go to some other secret
+cave, and leave us here.”
+
+“I hope they untie us before they leave, and give us something to eat,”
+ remarked the young inventor.
+
+For two hours longer the captives lay there, in most uncomfortable
+positions. Then Folwell and Munson, leaving the group of diamond makers
+who were grouped about the machinery, approached the captives.
+
+“Well,” remarked Munson, “we got ahead of you after all; didn't we. You
+thought you had our secret, but it will be a long while before you ever
+make diamonds.”
+
+“What are you going to do with us?” asked Tom.
+
+“Never mind. You came where you had no right to, and you must take the
+consequences.”
+
+“We did have a right to come here!” exclaimed Mr. Jenks. “I am entitled
+to know how the diamonds are made. I paid for the information, and you
+tricked me. If ever it's possible I'll have the whole gang arrested for
+swindling.”
+
+“You'll never get the chance!” declared Folwell. “You were given some
+diamonds for the money you invested, and that makes us square.”
+
+“No, it doesn't!” declared Mr. Jenks. “I invested the money to learn how
+to make diamonds, and you know it! You tricked me, and I had a right
+to try to discover your secret! I nearly have it, too, and I'll get it
+completely before I'm done with you!”
+
+“No, you won't!” boasted Folwell. “But we didn't come here to tell you
+that. We came to give you something to eat. We're not savages and
+we'll treat you as well as we can in spite of the fact that you are
+trespassers. We're going to give you some grub, but I warn you that any
+attempt to escape will mean that some of you will get hurt.”
+
+He signalled to some of his confederates. These men unbound the
+captives' arms, and stood over them while they ate some coarse food that
+was brought into the small cave. They were given coffee to drink, and
+then, when the simple meal was over, they were securely bound again,
+and left to themselves, while the diamond makers went back to their
+machinery.
+
+It was evident that they were going to attempt a big operation, for an
+unusually large quantity of the white stuff was prepared. The prisoners
+watched them idly. They could see some but not all of the operations. In
+this way several hours passed.
+
+Gloom possessed the hearts of Tom and his friends. Not only had their
+expedition been almost a failure so far, but the young inventor was
+worried lest the gang might discover and wreck his airship. This would
+prove a serious loss. Lying there in the semi-darkness the lad imagined
+all sorts of unpleasant happenings.
+
+At times he dozed off, as did the others. They had become somewhat used
+to the pain caused by the bonds, for their nerves were numb from the
+strain and pressure.
+
+Once, as he was lightly sleeping, Tom was awakened by hearing loud
+voices in the main cave. He looked out, rolling over slightly to get a
+better view. He saw the man who, once before had run in to give news of
+an approaching electrical storm.
+
+“Are you fellows all ready?” asked this same man again.
+
+“Yes. Is there another storm coming?”
+
+“Yes, and it's going to be a corker!” was the reply. “It's one of the
+worst I've ever seen. It's sweeping right up the valley. It'll be here
+in an hour.”
+
+“That's good. We need a big flash to make all the material we have
+prepared into diamonds. It's the biggest batch we ever tried. I hope it
+succeeds, for we're going to leave--” The rest was in so low a tone that
+Tom could not catch it.
+
+The storm messenger departed. Folwell and Munson busied themselves about
+the machinery. Tom dozed off again, dimly wondering what had become of
+Bill Renshaw, and whether the former ghost knew of their plight. The
+others were asleep, as the young inventor saw by the dim light of a
+lantern in the cave. Then, he too, shut his eyes.
+
+Tom was suddenly awakened by feeling some one's hands moving about his
+clothing. At first he thought it was one of the diamond-making gang, who
+had sneaked in to rob him. “Here! What are you up to?” exclaimed Tom.
+
+“Quiet!” cautioned a voice. “Are you all here?”
+
+“All of us--yes. But who are you?”
+
+“Easy--keep quiet, Tom Swift! I'm Bill Renshaw! I've been searching all
+over for you, since I got back to your cave and found it empty. Now I'm
+going to free you. I got in here by a secret entrance. Wait, I'll cut
+your ropes.” There was a slight sound, and an instant later Tom was
+freed from his bonds.
+
+
+
+
+CHAPTER XXIV--IN GREAT PERIL
+
+
+The young inventor could scarcely believe the good luck that had so
+unexpectedly come to him and his companions. No sooner was Tom able to
+move freely about than Bill Renshaw performed the same service for Mr.
+Jenks and the others, cautioning them to be quiet as he awakened them,
+and cut the ropes.
+
+“Bless my circulation!” exclaimed Mr. Damon, in a hoarse whisper. “How
+did you ever get here. I'd given ourselves up for lost.”
+
+“Oh, I came in off the mountain, as there's a big storm due,” explained
+the man. “There was no need of me playing the haunt in daytime, anyhow.
+I went to the cave, found you and your things gone, and I surmised that
+you might have walked into some trap.”
+
+“We did,” admitted Mr. Jenks, grimly.
+
+“Well, I hunted around until I found you,” went on Bill. “This mountain
+is honeycombed with caves, all opening from the large one, I know them
+better than these fellows do, so I could explore freely, and keep out of
+their sight. They didn't know that there was a second entrance to this
+place, but I did, and I made for it, when I couldn't find you in some of
+the other caves where I looked. And, sure enough, here you were.”
+
+“Well, we can't thank you enough,” said Mr. Parker. “But you say there
+is a big storm coming?”
+
+“One of the biggest that's been around these parts in some time,”
+ replied Bill.
+
+“Then perhaps the mountain will be destroyed,” went on the scientist, as
+calmly as if he had remarked that it might rain.
+
+“I hope nothing like that happens until we get away,” spoke Mr. Damon,
+fervently.
+
+“What had we better do?” inquired Tom.
+
+“Get away, unless you want to discover some more of their secrets,”
+ advised Bill. “Those fellows are planning something, but I can't find
+out what it is. They are suspicious of me, I think. But they are up to
+something, and I believe, it would be best for you to leave while you
+have the chance. It may not be healthy to stay. That's why I did my best
+to untie you.”
+
+“We appreciate what you have done,” declared Mr. Jenks, “but I want my
+rights. I must learn a few more facts about how to make diamonds from
+lightning flashes, and then I will have the same secret they cheated me
+out of. I think if we wait a while we may be able to see the parts of
+the process that are not quite clear to us. What do you say, Tom Swift?”
+
+“Well, I would like to learn the secret,” replied the lad, “and if Bill
+thinks it's safe to stay here a while longer--”
+
+“Oh, I guess it will be safe enough,” was the reply. “Those fellows
+won't bother about you now that they are about to make some more
+diamonds. Besides, they think you're all tied up. Yes, you can stay here
+and watch, I reckon. I've got a couple of guns, and--”
+
+“Then we'll stay,” decided Tom. “We can put up a better fight now.”
+
+Silently, in their prison, but which they could now leave whenever they
+pleased, the adventurers watched the diamond makers once more. The same
+process they had witnessed before was gone through with. The white balls
+were put inside the steel box and sealed up. Then they waited for the
+storm to reach its height.
+
+That this would not be long was evidenced by the mutterings of thunder
+which every moment grew louder. The outburst of electrical fury was
+likely to take place momentarily, and that it would be unusually severe
+was shown by the precautions taken by the diamond makers. They attached
+a number of extra wires, and brought out some insulated, hard rubber
+platforms, on which they themselves stood. Tom and Mr. Jenks were much
+interested in watching this detail of the work, and sought to learn how
+each part of the process was done.
+
+“I almost think we can make diamonds, Tom, when we get back to
+civilization,” whispered Mr. Jenks.
+
+“I hope we can,” answered Tom, “and we can't get back any too soon to
+suit me. I want to be in my airship again.”
+
+“I don't blame you. But look, they are getting ready to adjust the
+switch.”
+
+The adventurers ceased their whispered talk, and eagerly watched the
+diamond makers. Folwell and Munson were hurrying to and fro in the big
+cave, attending to the adjustments of the machinery.
+
+“On your insulated plates--all of you,” Folwell gave the order. “This
+is going to be a terrific storm. The gage shows twice the power we have
+ever used, and it's creeping up every minute! We'll have more diamonds
+than ever had before!”
+
+“Yes, if the mountain isn't destroyed,” added Mr. Parker, in a low
+voice. “I predict that it will be split from top to bottom!”
+
+“Comforting,” thought Tom, grimly.
+
+“I guess we're all ready,” said Folwell, in a low tone to Munson. “We'd
+better get insulated ourselves. I'm going to throw the switch.”
+
+He did so. A moment later the man who had before given warning of the
+storm came dashing in. He was very much excited.
+
+“It's awful!” he cried. “The lightning is striking all over! Big rocks
+are being split like logs of wood!”
+
+“Well, it can't do any damage in here,” said Munson. “We are well
+protected. Get on one of the plates,” and he motioned to one of the
+hard-rubber platforms that was not occupied. The roar and rumble of the
+storm outside had given place to short terrific crashes. In their small
+cave the adventurers could feel the solid ground shake.
+
+A bluish light began dancing about the electrical wires. There was a
+smell of sulphur in the air. Crash after crash resounded outside. A
+flash of flame lit up the whole interior of the cave. It came from the
+copper switch.
+
+“Something's wrong with the insulation!” cried Munson.
+
+“Don't go near it!” yelled Folwell. “If you value your life, stand
+still!”
+
+Hardly had he spoken than inside the cavern there sounded a report like
+that of a small cannon. A big ball of fire danced about the middle of
+the cave and then leaped on top of the steel box.
+
+“This is a fearful storm,” cried Munson.
+
+The adventurers in the cave did not know what to say or do. They were in
+deadly peril.
+
+Suddenly there came a crash louder than any that had preceded it. The
+whole side of the cave where the switches were was a mass of bluish
+flame. Then came a ripping, tearing sound, and a tangle of wires and
+copper connections were thrown to the floor. At the same time the steel
+box, containing the materials from which diamonds were made, turned
+blue, and flames shot from it.
+
+“It's all up with us!” cried Munson. “Run for it, everybody! The wires
+are down, and this place will be an electric furnace in another minute!”
+
+He leaped toward the exit from the cave.
+
+“What about those fellows?” asked Folwell, indicating the place where
+Tom and the others had been tied.
+
+“They'll have to do the best they can! It's every man for himself, now!”
+ yelled Munson. There was a wild scramble from the cavern.
+
+“Come on!” cried Tom. “We must escape! It's our only chance!”
+
+He leaped into the big cave, followed by the others. Already long
+tongues of electrical fire were shooting out from the walls and roof as
+Tom Swift and his companions, evading them as best they could, sought
+safety in flight.
+
+
+
+CHAPTER XXV--THE MOUNTAIN SHATTERED--CONCLUSION
+
+
+“Can't we get some of the diamonds?” cried Mr. Damon, as he raced along
+behind Tom. “Now's our chance. Those fellows have all gone!” The odd man
+made a grab for something as he ran.
+
+“It's as much as our lives are worth,” declared the young inventor. “We
+dare not stop! Come on!”
+
+“I'd like to investigate some of the machinery,” spoke Mr. Jenks, “but I
+wouldn't stop, even for that.”
+
+“The storm is too dangerous,” called Bill Renshaw. “I can show you a
+shorter way out than the one those fellows have taken. Follow me.”
+
+“No way can be too short,” said Mr. Parker, solemnly. “This mountain
+will go to pieces shortly, I think!”
+
+Tom shuddered. He remembered how narrow had been their escape when
+Earthquake Island sank into the sea. And that some terrific upheaval was
+now imminent might be judged from the awful reports that sounded more
+plainly as the adventurers raced toward the opening of the cave. It was
+like the bombardment of some doomed city.
+
+Mr. Jenks and Tom cast one longing look behind at the complicated and
+expensive machinery that had been installed in the cave by the diamond
+makers. They had abandoned it, and in it lay the secret of making
+precious gems. But there was no time to stop now, and investigate.
+
+“This way,” urged Bill Renshaw. “We'll soon be out.”
+
+“But won't it be dangerous to go outside?” asked Mr. Damon. “Shan't we
+be struck by lightning? There is some protection in here.”
+
+“None at all,” said Mr. Parker, quickly. “This mountain is a natural
+lightning rod. To stay here in this cave will be sure death when the
+storm gets directly over it. And that will be very soon. We must get
+on insulated ground. Is there any part of this mountain that does not
+contain iron ore?” the scientist asked of the former spirit.
+
+“Yes; the way out by which we are going lands on a dirt hill.”
+
+“That's good; then we may be saved.”
+
+On they ran. They had no lanterns, but the blue light of the
+electricity, as it leaped from point to point inside the cave, where
+there were outcroppings of iron ore, made the place bright enough to
+see.
+
+“Here we are!” cried Bill Renshaw at length. “Here's the way out!”
+
+Making a sudden turn in the winding passage he showed the adventurers
+a small opening in the side of the crag. In an instant they had passed
+through, and found themselves in daylight once more. The sudden glare
+almost blinded them, for, though the sky was overcast by clouds, from
+which jagged tongues of lightning played, the outside was much lighter
+than the dark cave.
+
+“I should say it was a storm!” cried Tom Swift. “See, it is striking
+every minute, and all around us!”
+
+In fact, lightning bolts were falling on every side of the adventurers.
+Every time the balls of fire struck, they burst open great stones,
+or seared a livid scar on the face of some cliff. As for Tom and the
+others, they stood on a dry dirt hill, in which, fortunately, there was
+no iron ore. To this fact they undoubtedly owed their lives, though
+had there been rain, to moisten the ground and make the earth a good
+conductor of electricity, they probably would have been badly shocked.
+But the electrical outburst was not accompanied by rain.
+
+Tom looked up. He saw a compact mass of cloud moving toward the summit
+of the mountain on the slope of which they stood. From this cloud there
+played shafts of reddish-green fire.
+
+“Look!” called the young inventor to Mr. Parker. The instant the latter
+saw the cloud, he cried:
+
+“We must get away from here by all means! That is the center of the
+storm. As soon as it gets over the mountain, where that lightning rod
+is, all the electrical fluid will be discharged in one bolt at the
+mountain, and it will be destroyed! We must run, but keep on the dirt
+places! Run for your lives!”
+
+They needed no second warning. Turning, they fled down the steep side of
+the mountain, slipping and stumbling, but taking care not to step on any
+iron ore. Behind them flashed the lightning bolts.
+
+Suddenly there was a most awful crash. It seemed as if the end of the
+world had come, and the ear drums of Tom and his companion almost burst
+with the fearful report. The concussion knocked them down, and they lay
+stunned for a moment.
+
+Following the terrible report there was a low, rumbling sound. Hardly
+knowing whether he was dead or alive, Tom opened his eyes and looked
+about him. What he saw caused him to cry out in terror.
+
+The whole mountain seemed bathed in fire. Great blue, red and green
+flashes played around it. Then the towering cliff seemed to melt and
+crumble up, and the great peak, the top of it containing the diamond
+makers' cave, from which they had fled but a few minutes before, the
+entire summit was toppled over into the valley on the other side, and in
+the direction opposite to that where the adventurers stood.
+
+Then came a profound silence, and the lightning ceased. The storm was
+over, and only the rattle of stones and boulders, as they came to rest
+in the valley below, reached the ears of our friends.
+
+“Phantom Mountain has been destroyed, just as I said it would be,” spoke
+Mr. Parker, solemnly. Once more he had prophesied correctly.
+
+For a few minutes the adventurers hardly knew what to say. They arose
+awkwardly from the ground where the shock had tossed them. Then Tom
+remarked, as calmly as possible:
+
+“Well, it's all over. I guess we may as well get back to our airship.”
+
+“What became of Munson and the others?” asked Mr. Damon.
+
+Mr. Jenks pointed to the trail, far below. The figures of some men,
+running madly, could be seen.
+
+“There they go,” he said; “I fancy we have seen the last of them.” And
+they had, for some time at least.
+
+There was little use lingering any longer on Phantom Mountain--indeed
+little of it was left on which to remain. Looking back toward the place
+where the cave had been, Tom and the others started forward again.
+The diamond-making machinery had all been destroyed. So, also, had the
+finished diamonds stored in the cavern and the large supply which had
+probably been made by the last terrific crash. No one would ever have
+them now. Tom and Mr. Jenks felt a sense of disappointment, but they
+were glad to have escaped with their lives. They sought their former
+camp, but the tent and all their food was buried under tons of earth and
+rocks.
+
+Three days later, after rather severe hardships, they were near the
+place where they had left the Red Cloud. They had suffered cold and
+hunger, for they had no food supplies, and, had it not been that Bill
+Renshaw knew the haunts of some game, of which they managed to snare
+some, they would have fared badly, for they had left their guns in the
+cave.
+
+“Well, there are the trees behind which I hope my airship is hidden,”
+ announced Tom, as they came to the spot. “Good old Red Cloud! Maybe we
+won't do some eating when we get aboard, eh?”
+
+“Bless my appetite! but we certainly will!” cried Mr. Damon.
+
+“There's somebody walking around the place,” spoke Mr. Jenks.
+
+“I hope it's no one who has damaged the ship,” came from Tom,
+apprehensively. He broke into a run, and soon confronted an aged miner,
+who seemed to have established a rude sort of camp near the airship.
+
+“Is anything the matter?” asked Tom, breathlessly. “Is my airship all
+right?”
+
+“I guess she's all right, stranger,” was the reply. “I don't know much
+about these contraptions, but I haven't touched her. I knowed she was an
+airship, for I've seen pictures of 'em, and I've been waiting until the
+owner came along.”
+
+“Why?” asked Tom, wonderingly.
+
+“Because I've got a proposition to make to you,” went on the miner, who
+said his name was Abe Abercrombie. “I've been a miner for a good many
+years, and I'm just back from Alaska, prospecting around here. I haven't
+had any luck, but I know of a gold mine in Alaska that will make us all
+rich. Only it needs an airship to get to it, and I've been figuring how
+to hire one. Then I comes along, and I sees this big one, and I makes up
+my mind to stay here until the owners come back. That's what I've done.
+Now, if I prove that I'm telling the truth, will you go to Alaska--to
+the valley of gold with me?”
+
+“I don't know,” answered Tom, to whom the proposition was rather sudden.
+“We've just had some pretty startling adventures, and we're almost
+starved. Wait until we get something to eat, and we'll talk. Come aboard
+the Red Cloud,” and the lad led the way to his craft which was in as
+good condition as when he left it to go to the diamond cave. Later he
+listened to the miner's story.
+
+Tom Swift did go to the valley of gold in Alaska, and what happened to
+him and his companions there will be told of in the next volume of this
+series, to be called “Tom Swift in the Caves of Ice; or, the Wreck of
+the Airship.”
+
+It did not take our friends long, after they had eaten a hearty meal,
+to generate some fresh gas, and start the Red Cloud on her homeward way.
+Tom wanted to take Bill Renshaw with him, but the old man said he would
+rather remain among the mountains where he had been born. So, after
+paying him well for his services, they said good-by to him. Abercrombie,
+the miner, also remained behind, but promised to call and see Tom in a
+few months.
+
+“Well, we didn't make any money out of this trip,” observed Mr. Jenks,
+rather dubiously, as they were nearing Shopton, after an uneventful
+trip. “I guess I owe you considerable, Tom Swift. I promised to get you
+a lot of diamonds, but all I have are those I had from my first visit to
+the cave.”
+
+“Oh, that's all right,” spoke Tom, easily. “The experience was worth all
+the trip cost.”
+
+“Speaking of diamonds, look here!” exclaimed Mr. Damon, suddenly, and he
+pulled out a double handful.
+
+“Where did you get them?” cried the others in astonishment.
+
+“I grabbed them up, as we ran from the cave,” said the eccentric man;
+“but, bless my gaiters! I forgot all about them until you spoke. We'll
+share them.”
+
+These diamonds, some of which were large, proved very valuable, though
+the total sum was far below what Mr. Jenks hoped to make when he started
+on the remarkable trip. Tom gave Mary Nestor a very fine stone, and it
+was set in a ring, instead of a pin, this time.
+
+On their arrival in Shopton, where Mr. Swift, the housekeeper, Mr.
+Jackson and Eradicate Sampson were much alarmed for Tom's safety, an
+attempt was made to manufacture diamonds, using a powerful electric
+current instead of lightning. But it was not a success, and so Mr. Jenks
+concluded to give up his search for the secret which was lost on Phantom
+Mountain.
+
+And now we will take leave of Tom Swift, to meet him again soon in other
+adventures he is destined to have in the caves of ice and the valley of
+gold.

+
+1.B. “Project Gutenberg” is a registered trademark. It may only be

+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation (“the Foundation”
+ or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently

+Gutenberg” is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included

+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase “Project Gutenberg” associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3. If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder. Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.

+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.

+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form. However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+“Plain Vanilla ASCII” or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original “Plain Vanilla ASCII” or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.

+- You pay a royalty fee of 20% of the gross profits you derive from
+ the use of Project Gutenberg-tm works calculated using the method
+ you already use to calculate your applicable taxes. The fee is
+ owed to the owner of the Project Gutenberg-tm trademark, but he
+ has agreed to donate royalties under this paragraph to the
+ Project Gutenberg Literary Archive Foundation. Royalty payments
+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and
+ sent to the Project Gutenberg Literary Archive Foundation at the
+ address specified in Section 4, “Information about donations to
+ the Project Gutenberg Literary Archive Foundation.”
+
+- You provide a full refund of any money paid by a user who notifies
+ you in writing (or by e-mail) within 30 days of receipt that s/he
+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+ money paid for a work or a replacement copy, if a defect in the
+ electronic work is discovered and reported to you within 90 days
+ of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+ distribution of Project Gutenberg-tm works.
+
+1.E.9. If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark. Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+“Defects,” such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right
+of Replacement or Refund” described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from. If you
+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5. Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org. Email contact links and up to date contact
+information can be found at the Foundation's web site and official
+page at http://pglaf.org
+
+For additional contact information:
+ Dr. Gregory B. Newby
+ Chief Executive and Director
+ gbnewby@pglaf.org
+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+ <h2>
+ CHAPTER I&mdash;A SUSPICIOUS JEWELER
+ </h2>
+ <p>
+ &ldquo;Well, Tom Swift, I don't believe you will make any mistake if you buy
+ that diamond,&rdquo; said the jeweler to a young man who was inspecting a tray
+ of pins, set with the sparkling stones. &ldquo;It is of the first water, and
+ without a flaw.&rdquo;
+ </p>
+ <p>
+ &ldquo;It certainly seems so, Mr. Track. I don't know much about diamonds, and
+ I'm depending on you. But this one looks to be all right.&rdquo;
+ </p>
+ <p>
+ &ldquo;Is it for yourself, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Er&mdash;no&mdash;that is, not exactly,&rdquo; and Tom Swift, the young
+ inventor of airships and submarines, blushed slightly.
+ </p>
+ <p>
+ &ldquo;Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I think she
+ would like a pin of this sort. True, it's rather expensive, but&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;No, it isn't for Mrs. Baggert, Mr. Track,&rdquo; and Tom seemed a bit
+ embarrassed.
+ </p>
+ <p>
+ &ldquo;No? Well, then, Tom&mdash;of course it's none of my affair, except to
+ sell you a good stone, But if this brooch is for a young lady, I can't
+ recommend anything nicer. Do you think you will take this; or do you
+ prefer to look at some others?&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I think this will do, Mr. Track. I guess I'll take&mdash;&rdquo;
+ </p>
+ <p>
+ Tom's words were interrupted by a sudden action on the part of the
+ jeweler. Mr. Track ran from behind the showcase and hastened toward the
+ front door.
+ </p>
+ <p>
+ &ldquo;Did you see him, Tom?&rdquo; he cried. &ldquo;I wonder which way he went?&rdquo;
+ </p>
+ <p>
+ &ldquo;Who?&rdquo; asked the lad, following the shopkeeper.
+ </p>
+ <p>
+ &ldquo;That man. He's been walking up and down in front of my place for the last
+ ten minutes&mdash;ever since you've been in here, in fact, and I don't
+ like his looks.&rdquo;
+ </p>
+ <p>
+ &ldquo;What did he do?&rdquo;
+ </p>
+ <p>
+ &ldquo;Nothing much, except to stare in here as if he was sizing my place up.&rdquo;
+ </p>
+ <p>
+ &ldquo;Sizing it up?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes. Getting the lay of the land, so he or some confederate could commit
+ a robbery, maybe.&rdquo;
+ </p>
+ <p>
+ &ldquo;A robbery? Do you think that man was a thief?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know that he was, Tom, and yet a jeweler has to be always on the
+ watch, and that isn't a joke, either, Tom Swift. Swindlers and thieves are
+ always on the alert for a chance to rob a jewelry store, and they work
+ many games.&rdquo;
+ </p>
+ <p>
+ &ldquo;I didn't notice any particular man looking in here,&rdquo; said Tom, who still
+ held the diamond brooch in his hand.
+ </p>
+ <p>
+ &ldquo;Well I did,&rdquo; went on the jeweler. &ldquo;I happened to glance out of the window
+ when you were looking at the pins, and I saw his eyes staring in here in a
+ suspicious manner. He may have a confederate with him, and, when you're
+ gone, one may come in, and pretend to want to look at some diamonds. Then,
+ when I'm showing him some, the other man will enter, engage my attention,
+ and the first man will slip out with a diamond ring or pin. It's often
+ done.&rdquo;
+ </p>
+ <p>
+ &ldquo;You seem to have it all worked out, Mr. Track,&rdquo; observed the lad, with a
+ smile. &ldquo;How do you know but what I'm in with a gang of thieves, and that
+ I'm only pretending to want to buy a diamond pin?&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I guess I haven't known you, Tom Swift, ever since you were big
+ enough to toddle, not to be sure about what you're up to. But I certainly
+ didn't like the looks of that man. However, let's forget about him. He
+ seems to have gone down the street, and, after all, perhaps I was
+ mistaken. Just wait until I show you a few more styles before you decide.
+ The young lady may like one of these,&rdquo; and the jeweler went to another
+ showcase and took out some more trays of brooches.
+ </p>
+ <p>
+ &ldquo;What makes you think she's a young lady, Mr. Track?&rdquo; asked the lad.
+ </p>
+ <p>
+ &ldquo;Oh, it's easy guessing, Tom. We jewelers are good readers of character. I
+ can size up a young fellow coming in here to buy an engagement or a
+ wedding ring, as soon as he enters the door. I suppose you'll soon be in
+ the market for one of those, Tom, if all the reports I hear about you are
+ true&mdash;you and a certain Mary Nestor.&rdquo;
+ </p>
+ <p>
+ &ldquo;I&mdash;er&mdash;I think I don't care for any of these pins,&rdquo; spoke Tom,
+ quickly, with a blush. &ldquo;I like the first lot best. I think I'll take the
+ one I had in my hand when that man alarmed you. Ha! That's odd! What did I
+ do with it?&rdquo;
+ </p>
+ <p>
+ Tom looked about on the showcase, and glanced down on the floor. He had
+ mislaid the brooch, but the jeweler, with a laugh, lifted it out of a tray
+ a moment later.
+ </p>
+ <p>
+ &ldquo;I saw you lay it down,&rdquo; he said. &ldquo;We jewelers have to be on the watch.
+ Here it is. I'll just put it in a box, and&mdash;&rdquo;
+ </p>
+ <p>
+ With an exclamation, Mr. Track gave a hasty glance toward his big show
+ window. Tom looked up, and saw a man's face peering in. At the sight of
+ it, he, too, uttered a cry of surprise.
+ </p>
+ <p>
+ The next instant the man outside knocked on the glass, apparently with a
+ piece of metal, making a sharp sound. As soon as he heard it, the jeweler
+ once more sprang from behind the showcase, and leaped for the door crying:
+ </p>
+ <p>
+ &ldquo;There's the thief! He's trying to cut a hole through my show window and
+ reach in and get something! It's an old trick. I'll get the police! Tom,
+ you stay here on guard!&rdquo; and before the lad could utter a protest, the
+ jeweler had opened the door, and was speeding down the street in the
+ gathering darkness.
+ </p>
+ <p>
+ Tom stared about him in some bewilderment. He was left alone in charge of
+ a very valuable stock of jewelry, the owner of which was racing after a
+ supposed thief, crying:
+ </p>
+ <p>
+ &ldquo;Police! Help! Thieves! Stop him, somebody!&rdquo;
+ </p>
+ <p>
+ &ldquo;This is a queer go,&rdquo; mused Tom. &ldquo;I wonder who that man was? He looked
+ like somebody I know, and yet I can't seem to place his face. I wonder if
+ he was trying to rob the place? Maybe there's another one&mdash;a
+ confederate&mdash;around here.&rdquo;
+ </p>
+ <p>
+ This thought rather alarmed Tom, so he went to the door, and looked up and
+ down the street. He could see no suspicious characters, but in the
+ direction in which the jeweler was running there was a little throng of
+ people, following Mr. Track after the man who had knocked on the window.
+ </p>
+ <p>
+ &ldquo;I wish I was there, instead of here,&rdquo; mused the lad. &ldquo;Still I can't
+ leave, or a thief might come in. Perhaps that was the game, and one of the
+ gang is hanging around, hoping the store will be deserted, so he can enter
+ and take what he likes.&rdquo;
+ </p>
+ <p>
+ Tom had read of such cases, and he at once resolved that he would not only
+ remain in the jewelry shop, but that he would lock the door, which he at
+ once proceeded to do. Then he breathed easier.
+ </p>
+ <p>
+ The town of Shopton, in the outskirts of which Tom lived with his father,
+ and where the scene above narrated took place, was none too well lighted
+ at night, and the lad had his doubts about the jeweler catching the
+ oddly-acting man, especially as the latter had a good start.
+ </p>
+ <p>
+ &ldquo;But some one may head him off,&rdquo; reasoned Tom. &ldquo;Though if they do catch
+ him, I don't see what they can prove against him. Hello, here I am
+ carrying this diamond pin around. I might lose it. Guess I'll put it back
+ on the tray.&rdquo;
+ </p>
+ <p>
+ He replaced in the proper receptacle one of the pins he had been examining
+ when the excitement occurred.
+ </p>
+ <p>
+ &ldquo;I wonder if Mary will like that?&rdquo; he said, softly. &ldquo;I hope she does.
+ Perhaps it would be better if she could come here herself and pick out one&mdash;&rdquo;
+ </p>
+ <p>
+ Tom's musing was suddenly interrupted by a sharp tattoo on the glass door
+ of the jewelry shop. With a start, he looked up, to see staring in on him
+ the face of the man who had been there before&mdash;the man of whom the
+ jeweler was even then in chase.
+ </p>
+ <p>
+ &ldquo;Why&mdash;why&mdash;&mdash;&rdquo; stammered Tom.
+ </p>
+ <p>
+ The man knocked again.
+ </p>
+ <p>
+ &ldquo;Tom&mdash;Tom Swift!&rdquo; he called. &ldquo;Don't you know me?&rdquo;
+ </p>
+ <p>
+ &ldquo;Know you&mdash;you?&rdquo; repeated the lad.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;don't you remember Earthquake Island&mdash;how we were nearly
+ killed there&mdash;don't you remember Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ Tom was so startled that he could only repeat words after the strange man,
+ who was talking to him from outside the glass door.
+ </p>
+ <p>
+ &ldquo;Yes, Mr. Jenks,&rdquo; was the reply. &ldquo;Mr. Barcoe Jenks, who makes diamonds. I
+ saw you in the store about to buy a diamond&mdash;I wanted to tell you not
+ to&mdash;I'll give you a better diamond than you can buy&mdash;I just
+ arrived in this place&mdash;I must have a private talk with you&mdash;Come
+ out&mdash;I'll share a wonderful secret with you.&rdquo;
+ </p>
+ <p>
+ A flood of memory came to Tom. He did recall the very strange man who
+ walked around Earthquake Island&mdash;where Tom and some friends had been
+ marooned recently&mdash;walked about with a pocketful of what he said were
+ diamonds. Now Barcoe Jenks was here.
+ </p>
+ <p>
+ &ldquo;I must see you privately, Tom Swift,&rdquo; went on Mr. Jenks, as he once more
+ tapped on the glass. &ldquo;Don't waste money buying diamonds, when you and I
+ can make better ones. Where can I have a talk with you? I&mdash;&rdquo; Mr.
+ Jenks suddenly looked down the dimly-lighted street. &ldquo;They're coming
+ back!&rdquo; he cried. &ldquo;I don't want to be seen. I'll call at your house later
+ to-night&mdash;be on the watch for me&mdash;until then&mdash;good-by!&rdquo;
+ </p>
+ <p>
+ He waved his hand, and was gone in an instant. Tom stood staring at the
+ glass door. He hardly knew whether to believe it or not&mdash;perhaps it
+ was all a dream.
+ </p>
+ <p>
+ He pinched himself to make sure that he was awake. Very substantial flesh
+ met his thumb and finger, and he felt the pain.
+ </p>
+ <p>
+ &ldquo;I'm awake all right,&rdquo; he murmured. &ldquo;But Barcoe Jenks here&mdash;and still
+ talking that nonsense about his manufactured diamonds. I think he must be
+ crazy. I wonder&mdash;&rdquo;
+ </p>
+ <p>
+ Once more the lad's musing was interrupted. He heard a murmur of excited
+ voices outside the store, on the street. Then the door of the jewelry shop
+ was tried. Mr. Track's face was pressed against the glass.
+ </p>
+ <p>
+ &ldquo;Open the door! Let me in, Tom!&rdquo; he called. &ldquo;I've caught the thief,&rdquo; and
+ as the lad unlocked the portal he saw that the jeweler held by the arm a
+ ragged lad. &ldquo;Ah; you scoundrel! I've caught you!&rdquo; cried the diamond
+ merchant, shaking the small chap, while Tom looked on, more mystified than
+ ever.

+ <h2>
+ CHAPTER II&mdash;A MIDNIGHT VISIT
+ </h2>
+ <p>
+ While Mr. Track, the jeweler, and several citizens, attracted by the chase
+ after the supposed thief, are crowded into the store, anxious to hear
+ explanations of the strange affair, I will take the opportunity to tell
+ you something of Tom Swift, the lad who is to figure in this story.
+ </p>
+ <p>
+ Many of you have already made his acquaintance, when he has been speeding
+ about in his airship or fast electric runabout, and to others we will
+ state that our hero first made his bow to the public in the book called
+ &ldquo;Tom Swift and His Motor-Cycle,&rdquo; the initial volume of this series.
+ </p>
+ <p>
+ In that story there was related how Tom made the acquaintance of an odd
+ individual, named Mr. Wakefield Damon, who was continually blessing
+ himself, some part of his anatomy, or his possessions. Mr. Damon was
+ riding a motor-cycle, and it started to climb a tree, to his pain and
+ fright. Afterward Tom purchased the machine, and had many adventures on
+ it, including a chase after a gang of men who had stolen a valuable patent
+ model belonging to Mr. Swift.
+ </p>
+ <p>
+ Mr. Swift and his son were both inventors. They lived together in a fine
+ house in the suburbs of Shopton, New York, and with them dwelt Mrs.
+ Baggert, the housekeeper (for Tom's mother was dead), and also Garret
+ Jackson, an expert engineer, who aided the young inventor and his father
+ in perfecting many machines.
+ </p>
+ <p>
+ There was also another semi-member of the household, to wit, Eradicate
+ Sampson, an eccentric colored man, who owned a mule called Boomerang.
+ Eradicate did odd jobs around the place, and the mule assisted his owner&mdash;that
+ is when the mule felt like it.
+ </p>
+ <p>
+ In the second volume of the series, entitled &ldquo;Tom Swift and His
+ Motor-Boat,&rdquo; there was related the incidents following a pursuit after a
+ gang of unprincipled men, who sought to get possession of some of Mr.
+ Swift's patents, and it was while in this boat that Tom, his father, and a
+ friend, Ned Newton, rescued from Lake Carlopa a Mr. John Sharp, who fell
+ from his burning balloon. Mr. Sharp was a skilled aeronaut, and after his
+ recovery he joined Tom in building a big airship, called the Red Cloud.
+ Tom's adventures in this craft are set down in detail in the third volume
+ of the series, called &ldquo;Tom Swift and His Airship.&rdquo; Not only did he and Mr.
+ Sharp and Mr. Damon make a great trip, but they captured some bank
+ robbers, and incidentally cleared themselves from the imputation of having
+ looted the vault of seventy-five thousand dollars, which charge was
+ fostered by a certain Mr. Foger, and his son Andy, who was Tom's enemy.
+ </p>
+ <p>
+ Not satisfied with having conquered the air, Tom and his father set to
+ work to gain a victory over the ocean. They built a boat that could
+ navigate under water, and, in the fourth book of the series, called &ldquo;Tom
+ Swift and His Submarine Boat,&rdquo; you will find an account of how they went
+ under the ocean to secure a sunken treasure, and the fight they had with
+ their enemies who sought to get it away from them. They went through many
+ perils, not the least of which was capture by a foreign warship.
+ </p>
+ <p>
+ In the fifth book, entitled &ldquo;Tom Swift and His Electric Runabout,&rdquo; there
+ was told the story of a wonderfully speedy electric automobile the young
+ inventor constructed, and how he made a great race in it, and saved from
+ ruin a bank, in which his father and Mr. Damon were interested.
+ </p>
+ <p>
+ Tom's ability as an inventor had, by this time, become well known. One
+ day, as related in a volume called &ldquo;Tom Swift and His Wireless Message,&rdquo;
+ he received a letter from a Mr. Hosmer Fenwick, of Philadelphia, asking
+ his aid in perfecting an airship which the resident of the Quaker City had
+ built, but which would not work. In his small monoplane, the Butterfly,
+ Tom and Mr. Damon went to Philadelphia, as Mr. Damon was acquainted with
+ Mr. Fenwick.
+ </p>
+ <p>
+ Tom carefully inspected the Whizzer which was the name of Mr. Fenwick's
+ airship, and, after some difficulties, succeeded in getting the electric
+ craft in shape to make a flight.
+ </p>
+ <p>
+ Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape May in the
+ Whizzer, but were caught in a terrific storm, and blown out to sea. The
+ wind became a hurricane, the airship was disabled, and wrecked in mid-air.
+ When it fell to earth it landed on one of the small West Indian islands,
+ but what was the terror of the three castaways to find that the island was
+ subject to earthquake shocks.
+ </p>
+ <p>
+ But the earth-tremors were not the only surprise in store for Tom and his
+ two friends, On the island they found five men and two ladies, who, by
+ strange chance, had been stranded there when the yacht Resolute, owned by
+ Mr. George Hosbrook, was wrecked in the same storm that disabled the
+ airship. Mr. Hosbrook, a millionaire, was taking a party of friends to the
+ West Indies.
+ </p>
+ <p>
+ When the castaways (among whom were Mr. and Mrs. Amos Nestor, parents of
+ Mary Nestor, a girl of whom Tom was very fond) found that there was danger
+ of the island being destroyed in an earthquake, they were in despair.
+ There seemed no way of being rescued, as the island was out of the line of
+ regular ship travel.
+ </p>
+ <p>
+ Tom, however, was resourceful. With the electrical apparatus from the
+ wrecked airship, he built a wireless plant, and sent messages for help,
+ broadcast over the ocean.
+ </p>
+ <p>
+ They were finally heard, and answered, by an operator on board the steamer
+ Camberanian, which came on under forced draught, and rescued Tom and his
+ friends. It was only just in time, for, no sooner had they gotten aboard
+ the steamer in lifeboats, than the whole island was destroyed by an
+ earthquake shock.
+ </p>
+ <p>
+ But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the
+ others, got safely home. Among the survivors from the yacht Resolute was a
+ Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom through
+ the glass window of the jewelry store. Mr. Jenks was a peculiar man. Tom
+ discovered this on Earthquake Island. Mr. Jenks carried with him some
+ stones which he said were diamonds. He asserted that he had made them, but
+ Tom did not know whether or not to believe this.
+ </p>
+ <p>
+ When it seemed that the castaways would not be saved Mr. Jenks offered Tom
+ a large sum in these same diamonds for some plan whereby he might escape
+ the earthquakes. Mr. Jenks said there was a certain secret in connection
+ with the manufactured diamonds that he had to solve&mdash;that he had been
+ defrauded of his rights&mdash;and that a certain Phantom Mountain figured
+ in it. But Tom, at that time, paid little attention to Mr. Jenks' talk.
+ The time was to come, however, when he would attach much importance to it.
+ </p>
+ <p>
+ When this story opens, Tom was more interested in Mr. Barcoe Jenks than in
+ any one else, and was wondering what he wanted to see him about. The young
+ inventor could not quite understand how Mr. Track, the jeweler, could come
+ back with a lad he suspected of being a thief, when the person who had
+ acted so suspiciously, and who had knocked on the glass, was the queer
+ man, Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Yes, Tom I caught him,&rdquo; the jeweler went on. &ldquo;I chased after him, and
+ nabbed him. It was hard work, too, for I'm not a good runner. Now, you
+ little rascal, tell me why you tried to rob my store?&rdquo; and the diamond
+ merchant shook the lad roughly.
+ </p>
+ <p>
+ &ldquo;I&mdash;I didn't try to rob your store,&rdquo; was the timid answer.
+ </p>
+ <p>
+ &ldquo;Well, perhaps you didn't, exactly, but your confederates did. Why did you
+ rap on the glass, and why were you staring in so intently?&rdquo;
+ </p>
+ <p>
+ &ldquo;I wasn't lookin' in.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, if it wasn't you, it was some one just like you. But why did you
+ run when I raced down the street?&rdquo;
+ </p>
+ <p>
+ &ldquo;I&mdash;I don't know,&rdquo; and the lad began to snivel. &ldquo;I&mdash;I jest ran&mdash;that's
+ all&mdash;'cause I see everybody else runnin', an' I thought there was a
+ fire.&rdquo;
+ </p>
+ <p>
+ &ldquo;Ha! That's a likely story! You ran because you are guilty! I'm going to
+ hand you over to the police.&rdquo;
+ </p>
+ <p>
+ &ldquo;Did he get anything, Mr. Track?&rdquo; asked one of the men who had joined the
+ jeweler in the chase.
+ </p>
+ <p>
+ &ldquo;No, I can't say that he did. He didn't get a chance. Tom Swift was in
+ here at the time. But this fellow was only waiting for a chance to steal,
+ or else to aid his confederates.&rdquo;
+ </p>
+ <p>
+ &ldquo;But, if he didn't take anything, I don't see how you can have him
+ arrested,&rdquo; went on the man.
+ </p>
+ <p>
+ &ldquo;On suspicion; that's how!&rdquo; asserted Mr. Track. &ldquo;Will some one get me a
+ constable?&rdquo;
+ </p>
+ <p>
+ &ldquo;I wouldn't call a constable,&rdquo; said Tom, quietly.
+ </p>
+ <p>
+ &ldquo;Why not?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because that isn't the person who looked in your window.&rdquo;
+ </p>
+ <p>
+ &ldquo;How do you know, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because that person came back while you were out. I saw him.&rdquo;
+ </p>
+ <p>
+ &ldquo;You saw him? Did he try to steal any of my diamonds, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;No, I guess he doesn't need any.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why not?&rdquo; There was wonder in the jeweler's tone.
+ </p>
+ <p>
+ &ldquo;Why, he claims he can make all he wants.&rdquo;
+ </p>
+ <p>
+ &ldquo;Make diamonds?&rdquo;
+ </p>
+ <p>
+ &ldquo;So he says.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why, he must be crazy!&rdquo; and Mr. Track laughed.
+ </p>
+ <p>
+ &ldquo;Perhaps he is,&rdquo; admitted Tom, &ldquo;I'm only telling you what he says. He's
+ the person who acted so suspiciously. He came back here, I'm telling you,
+ while you were running down the street, and spoke to me.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, then you know him?&rdquo; The jeweler's voice was suspicious.
+ </p>
+ <p>
+ &ldquo;I didn't at first,&rdquo; admitted Tom. &ldquo;But when he said he was Mr. Barcoe
+ Jenks, I remembered that I had met him when I was cast away on Earthquake
+ Island.&rdquo;
+ </p>
+ <p>
+ &ldquo;And he says he can make diamonds?&rdquo; asked Mr. Track.
+ </p>
+ <p>
+ &ldquo;What did he want of you?&rdquo; and the jeweler looked at Tom, quizzically.
+ </p>
+ <p>
+ &ldquo;He wanted to have a talk with me,&rdquo; replied the lad, &ldquo;and when he saw me
+ in your store, he tried to attract my attention by knocking on the glass.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's a queer way to do,&rdquo; declared Mr. Track. &ldquo;What did he want?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know exactly,&rdquo; answered Tom, not caring to go into details just
+ then. &ldquo;But I'm sure, Mr. Track, that you've got the wrong person there.
+ That lad never looked in the window, nor knocked on the glass.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's right&mdash;I didn't,&rdquo; asserted the captive.
+ </p>
+ <p>
+ The jeweler looked doubtful.
+ </p>
+ <p>
+ &ldquo;Why did you run?&rdquo; he asked.
+ </p>
+ <p>
+ &ldquo;I told you, I thought there was a fire.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's right, I don't believe he's the fellow you want,&rdquo; put in another
+ man. &ldquo;I was standing on the corner, near White's grocery store, and I
+ noticed this lad. That was before I heard you yelling, and saw you coming,
+ and then I joined in the chase. I guess the man you were after got away,
+ Track.&rdquo;
+ </p>
+ <p>
+ &ldquo;He did,&rdquo; asserted Tom. &ldquo;He came back here, a little while ago, and he ran
+ away just now, as he heard you coming.&rdquo;
+ </p>
+ <p>
+ &ldquo;Where did he go?&rdquo; asked the jeweler, eagerly.
+ </p>
+ <p>
+ &ldquo;I don't know,&rdquo; answered Tom. &ldquo;Only you've got the wrong lad here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, perhaps I have,&rdquo; admitted the diamond merchant. &ldquo;You can go,
+ youngster, but next time, don't run if you're not guilty.&rdquo;
+ </p>
+ <p>
+ &ldquo;I thought there was a fire,&rdquo; repeated the lad, as he hurriedly slipped
+ through the crowd in the store, and disappeared down the dark street.
+ </p>
+ <p>
+ &ldquo;Well, I guess the excitement's all over, and, anyhow, you weren't robbed,
+ Track,&rdquo; said a stout man, as he left the store. The others soon followed,
+ and Tom and the jeweler were once more alone in the shop.
+ </p>
+ <p>
+ &ldquo;Can you tell me something about this man, Tom?&rdquo; asked Mr. Track, eagerly.
+ &ldquo;So he really makes diamonds. Who is he?&rdquo;
+ </p>
+ <p>
+ &ldquo;I'd rather not tell&mdash;just now,&rdquo; replied the young inventor. &ldquo;I don't
+ take much stock in him, myself. I think he's visionary. He may think he
+ has made diamonds, and he may have made some stones that look like them.
+ I'm very skeptical.&rdquo;
+ </p>
+ <p>
+ &ldquo;If you could bring me some, Tom, I could soon tell whether they were real
+ or not. Can you?&rdquo;
+ </p>
+ <p>
+ The lad shook his head.
+ </p>
+ <p>
+ &ldquo;I don't expect to see Mr. Jenks again,&rdquo; he said. &ldquo;He talked rather wildly
+ about waiting to meet me, but that man is odd&mdash;crazy, perhaps&mdash;and
+ I don't imagine I'll see him. He's harmless, but he's eccentric. Well,
+ there was quite some excitement for a time.&rdquo;
+ </p>
+ <p>
+ &ldquo;I should say there was. I thought it was a plan to rob me,&rdquo; and the
+ jeweler began putting away the diamond pins. In fact, the excitement so
+ filled the minds of himself and Tom that neither of them thought any more
+ of the object of the lad's visit, and the young inventor departed without
+ purchasing the pin he had come after.
+ </p>
+ <p>
+ It was not until he was out on the street, walking toward his home, that
+ the matter came back to his mind.
+ </p>
+ <p>
+ &ldquo;I declare!&rdquo; he exclaimed. &ldquo;I didn't get that pin for Mary, after all!
+ Well, never mind, I have a week until her birthday, and I can get it
+ to-morrow.&rdquo;
+ </p>
+ <p>
+ He walked rapidly toward home, for the weather looked threatening, and Tom
+ had no umbrella. He was musing on the happenings of the evening when he
+ reached his house. His father was out, as was Garret Jackson, the
+ engineer; and Mrs. Baggert, the housekeeper, was entertaining a lady in
+ the sitting-room, so, as Tom was rather tired, he went directly to his own
+ room, and, a little later got into bed.
+ </p>
+ <p>
+ It was shortly after midnight when he was awakened by hearing a rattling
+ on the window of his room. The reason he was able to fix the time so
+ accurately was because as soon as he awakened he pressed a little electric
+ button, and it illuminated the face of a small clock on his bureau. The
+ hands pointed to five minutes past twelve.
+ </p>
+ <p>
+ &ldquo;Humph! That sounds like hail!&rdquo; exclaimed Tom, as he arose, and looked out
+ of the casement. &ldquo;I wonder if any of the skylights of the airship shed are
+ open? There might be some damage. Guess I'd better go out and take a
+ look.&rdquo;
+ </p>
+ <p>
+ He had mentally reasoned this far before he had looked out, and when he
+ saw that the moon was brightly shining in a clear sky, he was a bit
+ surprised.
+ </p>
+ <p>
+ &ldquo;Why&mdash;that wasn't hail,&rdquo; he murmured. &ldquo;It isn't even raining. I
+ wonder what it was?&rdquo;
+ </p>
+ <p>
+ He was answered a moment later, for a shower of fine gravel from the walk
+ flew up and clattered against the glass. With a start, Tom looked down,
+ and saw a dark figure standing under an apple tree.
+ </p>
+ <p>
+ &ldquo;Hello! Who's there?&rdquo; called the lad, after he had raised the sash.
+ </p>
+ <p>
+ &ldquo;It's I&mdash;Mr. Jenks,&rdquo; was the surprising answer.
+ </p>
+ <p>
+ &ldquo;Mr. Jenks?&rdquo; repeated Tom.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;Barcoe Jenks, of Earthquake Island.&rdquo;
+ </p>
+ <p>
+ &ldquo;You here? What do you want?&rdquo;
+ </p>
+ <p>
+ &ldquo;Can you come down?&rdquo;
+ </p>
+ <p>
+ &ldquo;What for?&rdquo;
+ </p>
+ <p>
+ &ldquo;Tom Swift, I've something very important to tell you,&rdquo; was the answer in
+ a low voice, yet which carried to Tom's ears perfectly. &ldquo;Do you want to
+ make a fortune for yourself&mdash;and for me?&rdquo;
+ </p>
+ <p>
+ &ldquo;How?&rdquo; Tom was beginning to think more and more that Mr. Jenks was crazy.
+ </p>
+ <p>
+ &ldquo;How? By helping me to discover the secret of Phantom Mountain, where the
+ diamonds are made! Will you?&rdquo;
+ </p>
+ <p>
+ &ldquo;Wait a minute&mdash;I'll come down,&rdquo; answered Tom, and he began to grope
+ for his clothes in the dim light of the little electric lamp.
+ </p>
+ <p>
+ What was the secret of Phantom Mountain? What did Mr. Jenks really want?
+ Could he make diamonds? Tom asked himself these questions as he hastily
+ dressed to go down to his midnight visitor.

+ <h2>
+ CHAPTER III&mdash;A STRANGE STORY
+ </h2>
+ <p>
+ &ldquo;Well, Mr. Jenks,&rdquo; began Tom, when he had descended to the garden, and
+ greeted the man who had acted so strangely on Earthquake Island, &ldquo;this is
+ rather an odd time for a visit.&rdquo;
+ </p>
+ <p>
+ &ldquo;I realize that, Tom Swift,&rdquo; was the answer, and the lad noticed that the
+ man spoke much more calmly than he had that evening at the jewelry shop.
+ &ldquo;I realize that, but I have to be cautious in my movements.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because there are enemies on my track. If they thought I was seeking aid
+ to discover the secret of Phantom Mountain, my life might pay the
+ forfeit.&rdquo;
+ </p>
+ <p>
+ &ldquo;Are you in earnest, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I certainly am, and, while I must apologize for awakening you at this
+ unseemly hour, and for the mysterious nature of my visit, if you will let
+ me tell my story, you will see the need of secrecy.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I don't mind being awakened,&rdquo; answered Tom, good-naturedly, &ldquo;but I
+ will be frank with you, Mr. Jenks. I hardly can believe what you have
+ stated to me several times&mdash;that you know how diamonds can be made.&rdquo;
+ </p>
+ <p>
+ &ldquo;I can prove it to you,&rdquo; was the quiet answer.
+ </p>
+ <p>
+ &ldquo;Yes, I know. For centuries men have tried to discover the secret of
+ transmuting base metals into gold, and how to make diamonds by chemical
+ means. But they have all been failures.&rdquo;
+ </p>
+ <p>
+ &ldquo;All except this process&mdash;the process used at Phantom Mountain,&rdquo;
+ insisted the queer man. &ldquo;Do you want to hear my story?&rdquo;
+ </p>
+ <p>
+ &ldquo;I have no objections.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then let me warn you,&rdquo; went on Mr. Jenks, &ldquo;that if you do hear it, you
+ will be so fascinated by it that I am sure you will want to cast your lot
+ in with mine, and aid me to get my rights, and solve the mystery. And I
+ also want to warn you that if you do, there is a certain amount of danger
+ connected with it.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm used to danger,&rdquo; answered Tom, quietly. &ldquo;Let me hear your story. But
+ first explain how you came to come here, and why you acted so strangely at
+ the jewelry store.&rdquo;
+ </p>
+ <p>
+ &ldquo;Willingly. I tried to attract your attention at the store, because I saw
+ that you were going to buy a diamond, and I didn't want you to.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why not?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because I want to present you with a beautiful stone, that will answer
+ your purpose as well or better, than any one you could buy. That will
+ prove my story better than any amount of words or argument. But I could
+ not attract your attention without also attracting that of the jeweler. He
+ became suspicious, gave chase, and I thought it best to vanish. I hope no
+ one was made to suffer for what may have been my imprudence.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, the lad whom Mr. Track caught was let go. But how did you happen to
+ come to Shopton?&rdquo;
+ </p>
+ <p>
+ &ldquo;To see you. I got your address from the owner of the yacht Resolute. I
+ knew that if there was one person who could aid me to recover my rights,
+ it would be you, Tom Swift. Will you help me? Will you come with me to
+ discover the secret of Phantom Mountain? If we go, it will have to be in
+ an airship, for in no other way, I think, can we come upon the place, as
+ it is closely guarded. Will you come? I will pay you well.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps I had better hear your story,&rdquo; said the young inventor. &ldquo;But
+ first let me suggest that we move farther away from the house. My father,
+ or Mr. Jackson, or the housekeeper, may hear us talking, and it may
+ disturb them. Come with me to my private shop,&rdquo; and Tom led the way to a
+ small building where he did experimental work. He unlocked the door with a
+ key he carried, turned on the lights, which were run by a storage battery,
+ and motioned Mr. Jenks to a seat.
+ </p>
+ <p>
+ &ldquo;Now I'll hear your story,&rdquo; said Tom.
+ </p>
+ <p>
+ &ldquo;I'll make it as short as possible,&rdquo; went on the queer man. &ldquo;To begin
+ with, it is now several years ago since a poorly dressed stranger applied
+ to me one night for money enough to get a meal and a bed to sleep in. I
+ was living in New York City at the time, and this was midnight, as I was
+ returning home from my club.
+ </p>
+ <p>
+ &ldquo;I was touched by the man's appearance, and gave him some money. He asked
+ for my card, saying he would repay me some day. I gave it to him, little
+ thinking I would hear from the man again. But I did. He called at my
+ apartments about a week later, saying he had secured work as an expert
+ setter of diamonds, and wanted to repay me. I did not want to take his
+ money, but the fact that such a sorry looking specimen of manhood as he
+ had been when I aided him, was an expert handler of gems interested me. I
+ talked with the man, and he made a curious statement.
+ </p>
+ <p>
+ &ldquo;This man, who gave his name as Enos Folwell, said he knew a place where
+ diamonds could be made, partly in a scientific manner, and partly by the
+ forces of nature. I laughed at him, but he told me so many details that I
+ began to believe him. He said he and some other friends of his, who were
+ diamond cutters, had a plant in the midst of the Rocky Mountains, where
+ they had succeeded in making several small, but very perfect diamonds.
+ They had come to the end of their rope, though, so to speak, because they
+ could not afford to buy the materials needed. Folwell said that he and his
+ companions had temporarily separated, had left the mountain where they
+ made diamonds, and agreed to meet there later when they had more money
+ with which to purchase materials. They had all agreed to go out into
+ civilization, and work for enough funds to enable them to go on with their
+ diamond making.
+ </p>
+ <p>
+ &ldquo;I hardly knew whether to believe the man or not, but he offered proof. He
+ had several small, but very perfect diamonds with him, and he gave them to
+ me, to have tested in any way I desired.
+ </p>
+ <p>
+ &ldquo;I promised to look into the matter, and, as I was quite wealthy, as, in
+ fact I am now, and if I found that the stones he gave me were real, I said
+ I might invest some money in the plant.&rdquo;
+ </p>
+ <p>
+ &ldquo;Were the diamonds good?&rdquo; asked Tom, who was beginning to be interested.
+ </p>
+ <p>
+ &ldquo;They were&mdash;stones of the first water, though small. An expert gem
+ merchant, to whom I took them, said he had never seen any diamonds like
+ them, and he wanted to know where I got them. Of course I did not tell
+ him.
+ </p>
+ <p>
+ &ldquo;To make a long story short, I saw Folwell again, told him to communicate
+ with his companions, and to tell them that I would agree to supply the
+ cash needed, if I could share in the diamond making. To this they agreed,
+ and, after some weeks spent in preparation, a party of us set out for
+ Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Phantom Mountain?&rdquo; interrupted Tom. &ldquo;Where is it?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know, exactly&mdash;it's somewhere in the Rockies, but the exact
+ location is a mystery. That is why I need your help. You will soon
+ understand the reason. Well, as I said, myself, Folwell and the others,
+ who were not exactly prepossessing sort of men, started west. When we got
+ to a small town, called Indian Ridge, near Leadville, Colorado, the men
+ insisted that I must now proceed in secret, and consent to be blindfolded,
+ as they were not yet ready to reveal the secret of the place where they
+ made the diamonds.
+ </p>
+ <p>
+ &ldquo;I did not want to agree to this, but they insisted, and I gave in,
+ foolishly perhaps. At any rate I was blindfolded one night, placed in a
+ wagon, and we drove off into the mountains. After traveling for some
+ distance I was led, still blindfolded, up a steep trail.
+ </p>
+ <p>
+ &ldquo;When the bandage was taken off my eyes I saw that I was in a large cave.
+ The men were with me, and they apologized for the necessity that caused
+ them to blindfold me. They said they were ready to proceed with the making
+ of diamonds, but I must promise not to seek to discover the secret until
+ they gave me permission, nor was I to attempt to leave the cave. I had to
+ agree.
+ </p>
+ <p>
+ &ldquo;Next they demanded that I give them a large sum, which I had promised
+ when they showed me, conclusively, that they could make diamonds. I
+ refused to do this until I had seen some of the precious stones, and they
+ agreed that this was fair, but said I would have to wait a few days.
+ </p>
+ <p>
+ &ldquo;Well, I waited, and, all that while, I was virtually a prisoner in the
+ cave. All I could learn was that it was in the midst of a great range,
+ near the top, and that one of the peaks was called Phantom Mountain. Why,
+ I did not learn until later.
+ </p>
+ <p>
+ &ldquo;At last one night, during a terrific thunder storm, the leader of the
+ diamond makers&mdash;Folwell&mdash;announced that I could now see the
+ stones made. The men had been preparing their chemicals for some days
+ previous. I was taken into a small chamber of the cave, and there saw
+ quite a complicated apparatus. Part of it was a great steel box, with a
+ lever on it.
+ </p>
+ <p>
+ &ldquo;We will let you make some diamonds for yourself,&rdquo; Folwell said to me, and
+ he directed me to pull the lever of the box, at a certain signal. The
+ signal came, just as a terrific crash of thunder shook the very mountain
+ inside of which we were. The box of steel got red-hot, and when it cooled
+ off it was opened, and was given a handful of white stones.
+ </p>
+ <p>
+ &ldquo;Were they diamonds?&rdquo; asked Tom, eagerly.
+ </p>
+ <p>
+ Mr. Jenks held out one hand. In the palm glittered a large stone&mdash;ostensibly
+ a diamond. In the rays of the moon it showed all the colors of the rainbow&mdash;a
+ beautiful gem. &ldquo;That is one of the stones I made&mdash;or rather that I
+ supposed I had made,&rdquo; went on Mr. Jenks. &ldquo;It is one of several I have, but
+ they have not all been cut and polished as has this one.
+ </p>
+ <p>
+ &ldquo;Naturally I was much impressed by what I saw, and, after I had made
+ certain tests which convinced me that the stones in the steel box were
+ diamonds, I paid over the money as I had promised. That was my undoing.&rdquo;
+ </p>
+ <p>
+ &ldquo;How?&rdquo;
+ </p>
+ <p>
+ &ldquo;As soon as the men got the cash, they had no further use for me. The next
+ I remember is eating a rude meal, while we discussed the future of making
+ diamonds. I knew nothing more until I found myself back in the small hotel
+ at Indian Ridge, whence I had gone some time previous, with the men, to
+ the cave in the mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;What happened?&rdquo; asked Tom, much surprised by the unexpected outcome of
+ the affair.
+ </p>
+ <p>
+ &ldquo;I had been tricked, that was all! As soon as the men had my money they
+ had no further use for me. They did not want me to learn the secret of
+ their diamond making, and they drugged me, carried me away from the cave,
+ and left me in the hotel.&rdquo;
+ </p>
+ <p>
+ &ldquo;Didn't you try to find the cave again?&rdquo;
+ </p>
+ <p>
+ &ldquo;I did, but without avail. I spent some time in the Rockies, but no one
+ could tell where Phantom Mountain was; in fact, few had heard of it, and I
+ was nearly lost searching for it.
+ </p>
+ <p>
+ &ldquo;I came back East, determined to get even. I had given the men a very
+ large sum of money, and, in exchange, they had given me several diamonds.
+ Probably the stones are worth nearly as much as the money I invested, but
+ I was cheated, for I was promised an equal share in the profits. These
+ were denied me, and I was tricked. I determined to be revenged, or at
+ least to discover the secret of making diamonds. It is my right.&rdquo;
+ </p>
+ <p>
+ &ldquo;I agree with you,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;But, up to the time I met you on Earthquake Island, I could form no plan
+ for discovering Phantom Mountain, and learning the secret of the diamond
+ makers,&rdquo; went on Mr. Jenks. &ldquo;I carried the gems about with me, as you
+ doubtless saw when we were on the island. But I knew I needed an airship
+ in which to fly over the mountains, and pick out the location of the cave
+ where the diamonds are made.&rdquo;
+ </p>
+ <p>
+ &ldquo;But how can you locate it, if you were blindfolded when you were taken
+ there, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I forgot to tell you that, on our journey into the mountains, and just
+ before I was carried into the cave, I managed to raise one corner of the
+ bandage. I caught a glimpse of a very peculiarly shaped cliff&mdash;it is
+ like a great head, standing out in bold relief against the moonlight, when
+ I saw it. That head of rock is near the cave. It may be the landmark by
+ which we can locate Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps,&rdquo; admitted the young inventor.
+ </p>
+ <p>
+ &ldquo;What I want to know is this,&rdquo; went on Mr. Jenks. &ldquo;Will you go with me on
+ this quest&mdash;go in your airship to discover the secret of the diamond
+ makers? If you will, I will share with you whatever diamonds we can
+ discover, or make; besides paying all expenses. Will you go, Tom Swift?&rdquo;
+ </p>
+ <p>
+ The young inventor did not know what to answer. How far was Mr. Jenks to
+ be trusted? Were the stones he had real diamonds? Was his story,
+ fantastical as it sounded&mdash;true? Would it be safe for Tom to go?
+ </p>
+ <p>
+ The lad asked himself these questions. Mr. Jenks saw his hesitation.
+ </p>
+ <p>
+ &ldquo;Here,&rdquo; said the strange man, &ldquo;I will prove what I say. Take this diamond.
+ I intended it for you, anyhow, for what you did for me on Earthquake
+ Island. Take it, and&mdash;and give it to the person for whom you were
+ about to purchase a diamond to-night. But, first of all, take it to a gem
+ expert, and get his opinion. That will prove the truth of what I say, Tom
+ Swift, and I feel sure that you will cast your lot in with mine, and help
+ me to discover the secret of Phantom Mountain, and aid me to get my rights
+ from the diamond makers!&rdquo;

+ <h2>
+ CHAPTER IV&mdash;ANDY FOGER GETS A FRIGHT
+ </h2>
+ <p>
+ Tom Swift considered a few minutes. On the face of it, the proposition
+ appealed to him. He had been home some time now after his adventures on
+ Earthquake Island, and he was beginning to long for more excitement. The
+ search for the mysterious mountain, and the cave of the diamond makers,
+ might offer a new field for him. But there came to him a certain distrust
+ of Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I don't like to doubt your word,&rdquo; began Tom, slowly, &ldquo;but you know, Mr.
+ Jenks, that some of the greatest chemists have tried in vain to make
+ diamonds; or, at best, they have made only tiny ones. To think that any
+ man, or set of men, made real diamonds as large as the ones you have,
+ doesn't seem&mdash;well&mdash;&rdquo; and Tom hesitated.
+ </p>
+ <p>
+ &ldquo;You mean you can hardly believe me?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I guess that's it,&rdquo; assented Tom.
+ </p>
+ <p>
+ &ldquo;I don't blame you a bit!&rdquo; exclaimed the odd man. &ldquo;In fact, I didn't
+ believe it when they told me they could make diamonds. But they proved it
+ to me. I'm ready now to prove it to you.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll tell you what I'll do. Here's this one stone, cut ready for setting.
+ Here's another, uncut,&rdquo; and Mr. Jenks drew from his pocket what looked
+ like a piece of crystal. &ldquo;Take them to any jeweler,&rdquo; he resumed&mdash;&ldquo;to
+ the one in whose place I saw you to-night. I'll abide by the verdict you
+ get, and I'll come here to-morrow night, and hear what you have to say.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why do you come at night?&rdquo; asked Tom, thinking there was something
+ suspicious in that.
+ </p>
+ <p>
+ &ldquo;Because my life might be in danger if I was seen talking to you, and
+ showing you diamonds in the daytime&mdash;especially just now.
+ </p>
+ <p>
+ &ldquo;Why at this particular time?&rdquo;
+ </p>
+ <p>
+ &ldquo;For the reason that the diamond makers are on my trail. As long as I
+ remained quiet, after their shabby treatment of me, and did not try to
+ discover their secret, they were all right. But, after I realized that I
+ had been cheated out of my rights, and when I began to make an
+ investigation, with a view to discovering their secret whereabouts, I
+ received mysterious and anonymous warnings to stop.&rdquo;
+ </p>
+ <p>
+ &ldquo;But I did not. I came East, and tried to get help to discover the cave of
+ the diamond makers, but I was unsuccessful. I needed an airship, as I said,
+ and no person who could operate one, would agree to go with me on the
+ quest. Again I received a warning to drop all search for the diamond
+ makers, but I persisted, and about a week ago I found I was being
+ shadowed.&rdquo;
+ </p>
+ <p>
+ &ldquo;Shadowed; by whom?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;By a man I never remember seeing, but who, I have no doubt, is one of the
+ diamond-making gang.&rdquo;
+ </p>
+ <p>
+ &ldquo;Do you think he means you harm?&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm sure of it. That is the reason I have to act so in secret, and come
+ to see you at night. I don't want those scoundrels to find out what I am
+ about to do. On my return from Earthquake Island, I again endeavored to
+ interest an airship man in my plan, but he evidently thought me insane.
+ Then I thought of you, as I had done before, but I was afraid you, too,
+ would laugh at my proposition. However, I decided to come here, and I did.
+ It seemed almost providential that my first view of you was in a jewelry
+ shop, looking at diamonds. I took it as a good omen. Now it remains with
+ you. May I call here to-morrow night, and get your answer?&rdquo;
+ </p>
+ <p>
+ Tom Swift made up his mind quickly. After all it would be easy enough to
+ find out if the diamonds were real. If they were, he could then decide
+ whether or not to go with Mr. Jenks on the mysterious quest. So he
+ answered:
+ </p>
+ <p>
+ &ldquo;I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow night.
+ In the meanwhile, for my own satisfaction, I'll let an expert look at
+ these stones.&rdquo;
+ </p>
+ <p>
+ &ldquo;Get the greatest diamond expert in the world, and he'll pronounce them
+ perfect!&rdquo; predicted the odd man. &ldquo;Now I'll bid you goodnight, and be
+ going. I'll be here at this time to-morrow.&rdquo;
+ </p>
+ <p>
+ As Mr. Jenks turned aside there was a movement among the trees in the
+ orchard, and a shadowy figure was seen hurrying away.
+ </p>
+ <p>
+ &ldquo;Who's that?&rdquo; asked the diamond man, in a hoarse whisper. &ldquo;Did you see
+ that, Tom Swift? Some one was here&mdash;listening to what I said! Perhaps
+ it was the man who has been shadowing me!&rdquo;
+ </p>
+ <p>
+ &ldquo;I think not. I guess it was Eradicate Sampson, a colored man who does
+ work for us,&rdquo; said Tom. &ldquo;Is that you, Rad?&rdquo; he called.
+ </p>
+ <p>
+ &ldquo;Yais, sah, Massa Tom, heah I is!&rdquo; answered the voice of the negro, but it
+ came from an entirely different direction than that in which the shadowy
+ figure had been seen.
+ </p>
+ <p>
+ &ldquo;Where are you, Rad?&rdquo; called the young inventor.
+ </p>
+ <p>
+ &ldquo;Right heah,&rdquo; was the reply, and the colored man came from the direction
+ of the stable. &ldquo;I were jest out seein' if mah mule Boomerang were all
+ right. Sometimes he's restless, an' don't sleep laik he oughter.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then that wasn't you over in the orchard?&rdquo; asked Tom, in some uneasiness.
+ </p>
+ <p>
+ &ldquo;No, sah, I ain't been in de orchard. I were sleepin' in mah shack, till
+ jest a few minutes ago, when I got up, an' went in t' see Boomerang. I had
+ a dream dat some coon were tryin t' steal him, an' it sort ob 'sturbed me,
+ laik.&rdquo;
+ </p>
+ <p>
+ &ldquo;If it wasn't your man, it was some one else,&rdquo; said Mr. Jenks, decidedly.
+ </p>
+ <p>
+ &ldquo;We'll have a look!&rdquo; exclaimed Tom. &ldquo;Here, Rad, come over and scurry among
+ those trees. We just saw some one sneaking around.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll sure do dat!&rdquo; cried the colored man. &ldquo;Mebby it were somebody arter
+ Boomerang! I'll find 'em.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe it was any one after the mule,&rdquo; murmured Mr. Jenks, &ldquo;but
+ it certainly was some one&mdash;more likely some one after me.&rdquo;
+ </p>
+ <p>
+ The three made a hasty search among the trees, but the intruder had
+ vanished, leaving no trace. They went out into the road, which the moon
+ threw into bold relief along its white stretch, but there was no figure
+ scurrying away.
+ </p>
+ <p>
+ &ldquo;Whoever it was, is gone,&rdquo; spoke Tom. &ldquo;You can go back to bed, Rad,&rdquo; for
+ the colored man, of late, had been sleeping in a shack on the Swift
+ premises.
+ </p>
+ <p>
+ &ldquo;And I guess it's time for me to go, too,&rdquo; added Mr. Jenks. &ldquo;I'll be here
+ to-morrow night, Tom, and I hope your answer will be favorable.&rdquo;
+ </p>
+ <p>
+ Tom did not sleep well the remainder of the night, for his fitful slumbers
+ were disturbed by dreams of enormous caves, filled with diamonds, with
+ dark, shadowy figures trying to put him into a red-hot steel box. Once he
+ awakened with a start, and put his hand under his pillow to feel if the
+ two stones Mr. Jenks had given him, were still there. They had not been
+ disturbed.
+ </p>
+ <p>
+ Tom made up his mind to find out if the stones were really diamonds,
+ before saying anything to his father about the chance of going to seek
+ Phantom Mountain. And the young inventor wished to get the opinion of some
+ other jeweler than Mr. Track&mdash;at least, at first.
+ </p>
+ <p>
+ &ldquo;Though if this one proves to be a good gem, I'll have Mr. Track set it in
+ a brooch, and give it to Mary for her birthday,&rdquo; decided the young
+ inventor. &ldquo;Guess I'll take a run over to Chester in the Butterfly, and see
+ what one of the jewelers there has to say.&rdquo;
+ </p>
+ <p>
+ In addition to his big airship, Red Cloud, Tom owned a small, swift
+ monoplane, which he called Butterfly. This had been damaged by Andy Foger
+ just before Tom left on the trip that ended at Earthquake Island, but the
+ monoplane had been repaired, and Andy had left town, not having returned
+ since.
+ </p>
+ <p>
+ Telling his father that he was going off on a little business trip, which
+ he often did in his aeroplane, Tom, with the aid of Mr. Jackson, the
+ engineer, wheeled the Butterfly out of its shed.
+ </p>
+ <p>
+ Adjusting the mechanism, and seeing that it was in good shape, Tom took
+ his place in one of the two seats, for the monoplane would carry two. Mr.
+ Jackson then spun the propellers, and, with a crackle and roar the motor
+ started. Over the ground ran the dainty, little aeroplane, until, having
+ momentum enough, Tom tilted the wing planes and the machine sailed up into
+ the air.
+ </p>
+ <p>
+ Rising about a thousand feet, and circling about several times to test the
+ wind currents, Tom headed his craft toward Chester, a city about fifty
+ miles from Shopton. In his pocket, snugly tucked away, were the two stones
+ Mr. Jenks had given him.
+ </p>
+ <p>
+ It was not long before Tom saw, looming up in the distance the church
+ spires and towering factory chimneys of Chester, for his machine was a
+ speedy one, and could make ninety miles an hour when driven. But now a
+ slower speed satisfied our hero.
+ </p>
+ <p>
+ &ldquo;I'll just drop down outside of the city,&rdquo; he reasoned, &ldquo;for too much of a
+ crowd gathers when I land in the street. Besides I might frighten horses,
+ and then, too, it's hard to get a good start from the street. I'll leave
+ it in some barn until I want to go back.&rdquo;
+ </p>
+ <p>
+ Tom sent his craft down, in order to pick out a safe place for a landing.
+ He was then over the suburbs of the city, and was following the line of a
+ straight country road.
+ </p>
+ <p>
+ &ldquo;Looks like a good place there,&rdquo; he murmured. &ldquo;I'll shut off the motor,
+ and vol-plane down.&rdquo;
+ </p>
+ <p>
+ Suiting the action to the word, Tom shut off his power. The little craft
+ dipped toward the ground, but the lad threw up the forward planes, and
+ caught a current of air that sent him skimming along horizontally.
+ </p>
+ <p>
+ As he got nearer to the ground, he saw the figure of a lad riding a
+ bicycle along the country highway. Something about the figure struck Tom
+ as being familiar, and he recognized the cyclist a moment later.
+ </p>
+ <p>
+ &ldquo;It's Andy Foger!&rdquo; said Tom, in a whisper. &ldquo;I wondered where he had been
+ keeping himself since he damaged the Butterfly. Evidently he doesn't dare
+ venture back to Shopton. Well, here's where I give him a scare.&rdquo;
+ </p>
+ <p>
+ Tom's monoplane was making no more noise, now, than a soaring bird. He was
+ gliding swiftly toward the earth, and, with the plan in his mind of
+ administering some sort of punishment to the bully, he aimed the machine
+ directly at him.
+ </p>
+ <p>
+ Nearer and nearer shot the monoplane, as quietly as a sheet of paper might
+ fall. Andy pedaled on, never looking up nor behind him, A moment later, as
+ Tom threw up his headplanes, to make his landing more easy, and just as he
+ swooped down at one side of the cyclist, our hero let out a most alarming
+ yell, right into Andy's ear.
+ </p>
+ <p>
+ &ldquo;Now I've got you!&rdquo; he shouted. &ldquo;I'll teach you to slash my aeroplane!
+ Come with me!&rdquo;
+ </p>
+ <p>
+ Andy gave one look at the white bird-like apparatus that had flown up
+ beside him so noiselessly, and, being too frightened to recognize Tom's
+ voice, must have thought that he had been overtaken by some supernatural
+ visitor.
+ </p>
+ <p>
+ Andy gave a yell like an Indian, about to do a stage scalping act, and
+ fairly dived over the handlebars of his bicycle, sprawling in a heap on
+ the dusty road.
+ </p>
+ <p>
+ &ldquo;I guess that will hold you for a while,&rdquo; observed Tom, grimly, as he put
+ on the ground-brake and brought his monoplane to a stop not far from the
+ fallen rider.

+ <h2>
+ CHAPTER V&mdash;A MYSTERIOUS MAN
+ </h2>
+ <p>
+ For several minutes Andy Foger did not arise. He remained prostrate in the
+ dust, and Tom, observing him, thought perhaps the bully might have been
+ seriously injured. But, a little later, Andy cautiously raised his head,
+ and inquired in a frightened voice:
+ </p>
+ <p>
+ &ldquo;Is it&mdash;is it gone?&rdquo;
+ </p>
+ <p>
+ &ldquo;Is what gone?&rdquo; asked Tom, grimly.
+ </p>
+ <p>
+ At the sound of his voice, Andy looked up. &ldquo;Was that you, Tom Swift?&rdquo; he
+ demanded. &ldquo;Did you knock me off my wheel?&rdquo;
+ </p>
+ <p>
+ &ldquo;My monoplane and I together did,&rdquo; was the reply; &ldquo;or, rather, we didn't.
+ It was the nervous reaction caused by your fright, and the knowledge that
+ you had done wrong, that made you jump over the handlebars. That's the
+ scientific explanation.&rdquo;
+ </p>
+ <p>
+ &ldquo;You&mdash;you did it!&rdquo; stammered Andy, getting to his feet. He wasn't
+ hurt much, Tom thought.
+ </p>
+ <p>
+ &ldquo;Have it your own way,&rdquo; resumed our hero. &ldquo;Did you think it was a
+ hob-goblin in a chariot of fire after you, Andy?&rdquo;
+ </p>
+ <p>
+ &ldquo;Huh! Never mind what I thought! I'll have you arrested for this!&rdquo;
+ </p>
+ <p>
+ &ldquo;Will you? Delighted, as the boys say. Hop in my airship and I'll take you
+ right into town. And when I get you there I'll make a charge of malicious
+ mischief against you, for breaking the propeller of the Butterfly and
+ slashing her wings. I've mended her up, however, so she goes better than
+ ever, and I can take you to the police station in jig time. Want to come,
+ Andy?&rdquo;
+ </p>
+ <p>
+ This was too much for the bully. He knew that Tom would have a clear case
+ against him, and he did not dare answer. Instead he shuffled over to where
+ his wheel lay, picked it up, and rode slowly off.
+ </p>
+ <p>
+ &ldquo;Good riddance,&rdquo; murmured Tom. He looked about, and saw that he was near a
+ house, in the rear of which was a good-sized barn. &ldquo;Guess I'll ask if I
+ can leave the Butterfly there,&rdquo; he murmured, and, ringing the doorbell, he
+ was greeted by a man.
+ </p>
+ <p>
+ &ldquo;I'll pay you if you'll let me store my machine in the barn a little
+ while, until I go into the city, and return,&rdquo; spoke the lad.
+ </p>
+ <p>
+ &ldquo;Indeed, you're welcome to leave it there without pay,&rdquo; was the answer.
+ &ldquo;I'm interested in airships, and, I'll consider it a favor if you'll let
+ me look yours over while it's here.&rdquo;
+ </p>
+ <p>
+ Tom readily agreed, and a few minutes later he had caught a trolley going
+ into the city. He was soon in one of the largest jewelry stores of
+ Chester.
+ </p>
+ <p>
+ &ldquo;I'd like to get an expert opinion as to whether or not those stones are
+ diamonds,&rdquo; spoke Tom, to the polite clerk who came up to wait on him, and
+ our hero handed over the two gems which Mr. Jenks had given him. &ldquo;I'm
+ willing to pay for the appraisement, of course,&rdquo; the young inventor added,
+ as he saw the clerk looking rather doubtfully at him, for Tom had on a
+ rough suit, which he always donned when he flew in his monoplane.
+ </p>
+ <p>
+ &ldquo;I'll turn them over to our Mr. Porter, a gem expert,&rdquo; said the clerk.
+ &ldquo;Please be seated.&rdquo;
+ </p>
+ <p>
+ The young man disappeared into a private office with the stones, and Tom
+ waited. He wondered if he was going to have his trouble for his pains.
+ Presently two elderly gentlemen came from the little room, on the glass
+ door of which appeared the word &ldquo;Diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;Who brought these stones in?&rdquo; asked one of the men, evidently the
+ proprietor, from the deference paid him by the clerk. The latter motioned
+ to Tom.
+ </p>
+ <p>
+ &ldquo;Will you kindly step inside here?&rdquo; requested the elderly man. When the
+ door was closed, Tom found himself in a room which was mostly taken up
+ with a bench for the display of precious stones, a few chairs, and some
+ lights arranged peculiarly; while various scales and instruments stood on
+ a table.
+ </p>
+ <p>
+ &ldquo;You wished an opinion on&mdash;on these?&rdquo; queried the proprietor of the
+ place. Tom noticed at once that the word &ldquo;diamonds&rdquo; was not used.
+ </p>
+ <p>
+ &ldquo;I wanted to find out if they were of any value,&rdquo; he said. &ldquo;Are they
+ diamonds?&rdquo;
+ </p>
+ <p>
+ &ldquo;Would you mind stating where you got them?&rdquo; asked the other of the two
+ men.
+ </p>
+ <p>
+ &ldquo;Is that necessary?&rdquo; inquired the lad. &ldquo;I came by them in a legitimate
+ manner, if that's what you mean, and I can satisfy you on that point. I am
+ willing to pay for any information you may give me as to their value.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, it isn't that,&rdquo; the proprietor hastened to assure him. &ldquo;But these are
+ diamonds of such a peculiar kind, so perfect and without a flaw, that I
+ wondered from what part of the world they came.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then they are diamonds?&rdquo; asked Tom, eagerly.
+ </p>
+ <p>
+ &ldquo;The finest I have ever tested!&rdquo; declared the other man, evidently Mr.
+ Porter, the gem expert. &ldquo;They are a joy to look at, Mr. Roberts,&rdquo; he went
+ on, turning to the proprietor. &ldquo;If it is possible to get a supply of them
+ you would be justified in asking half as much again as we charge for
+ African or Indian diamonds. The Kimberly products are not to be compared
+ to these,&rdquo; and he looked at the two stones in his hand&mdash;the one cut,
+ and sparkling brilliantly, the other in a rough state.
+ </p>
+ <p>
+ &ldquo;Do you care to state where these diamonds came from?&rdquo; asked Mr. Roberts,
+ looking critically at Tom.
+ </p>
+ <p>
+ &ldquo;I had rather not,&rdquo; answered the lad. &ldquo;It is enough for me to know that
+ they are diamonds. How much is your charge?&rdquo;
+ </p>
+ <p>
+ &ldquo;Nothing,&rdquo; was the unexpected answer. &ldquo;We are very glad to have had the
+ opportunity of seeing such stones. Is there any chance of getting any
+ more?&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps,&rdquo; answered Tom, as he accepted the gems which the expert held out
+ to him.
+ </p>
+ <p>
+ &ldquo;Then might we speak for a supply?&rdquo; went on Mr. Roberts, eagerly. &ldquo;We will
+ pay you the full market price.&rdquo;
+ </p>
+ <p>
+ &ldquo;What is the value of these stones?&rdquo; asked Tom.
+ </p>
+ <p>
+ Mr. Roberts looked at his gem expert.
+ </p>
+ <p>
+ &ldquo;It is difficult to say,&rdquo; was the answer of the man who had handed Tom the
+ gems. &ldquo;They are so far superior to the usual run of diamonds, that I feel
+ justified in saying that the cut one would bring fifteen hundred dollars,
+ anywhere. In fact, I would offer that for it. The other is larger, though
+ what it would lose in cutting would be hard to say. I should say it was
+ worth two thousand dollars as it is now.&rdquo;
+ </p>
+ <p>
+ &ldquo;Thirty-five hundred dollars for these two stones!&rdquo; exclaimed Tom.
+ </p>
+ <p>
+ &ldquo;They are worth every cent of it,&rdquo; declared Mr. Roberts. &ldquo;Do you want to
+ sell?&rdquo;
+ </p>
+ <p>
+ Tom shook his head. He could scarcely believe the good news. Mr. Jenks had
+ told the truth. Now the young inventor could go with him to seek the
+ diamond makers.
+ </p>
+ <p>
+ &ldquo;Can you get any more of these?&rdquo; went on Mr. Roberts.
+ </p>
+ <p>
+ &ldquo;I think so&mdash;that is I don't know&mdash;I am going to try,&rdquo; answered
+ the lad.
+ </p>
+ <p>
+ &ldquo;Then if you succeed I wish you would sell us some,&rdquo; fairly begged the
+ proprietor of the store.
+ </p>
+ <p>
+ &ldquo;I will,&rdquo; promised Tom, but he little knew what lay before him, or perhaps
+ he would not have made that promise. He thanked the diamond merchant for
+ his kindness, and arranged to have the cut stone set in a pin for Miss
+ Nestor. The uncut gem Tom took away with him.
+ </p>
+ <p>
+ Thinking of many things, and wondering how best to start in his airship
+ Red Cloud for the mysterious Phantom Mountain, Tom hurried back to where
+ he had left the monoplane, wheeled it out, and was soon soaring through
+ the air toward Shopton.
+ </p>
+ <p>
+ &ldquo;I think I'll go with Mr. Jenks,&rdquo; he decided, as he prepared for a landing
+ in the open space near his aeroplane shed. &ldquo;It will be a risky trip,
+ perhaps, but I've taken risks before. When Mr. Jenks comes to-night I'll
+ tell him I'll help him to get his rights, and discover the secret of the
+ diamond makers.&rdquo;
+ </p>
+ <p>
+ As Tom was wheeling the Butterfly into the shed, Eradicate came out to
+ help him.
+ </p>
+ <p>
+ &ldquo;Dere's a gen'man here to see yo', Massa Tom,&rdquo; said the colored man.
+ </p>
+ <p>
+ &ldquo;Who is it?&rdquo;
+ </p>
+ <p>
+ &ldquo;I dunno. He keep askin' ef yo' de lad what done bust up Earthquake
+ Island, an' send lightnin' flashes up to de sky, an' all sech questions
+ laik dat.&rdquo;
+ </p>
+ <p>
+ &ldquo;It isn't Mr. Damon; is it, Rad? He hasn't been around in some time.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, Massa Tom, it ain't him. I knows dat blessin' man good an' proper. I
+ jest wish he'd bless mah mule Boomerang some day, an' take some oh de
+ temper out ob him. No, sah, it ain't Massa Damon. De gen'man's in de
+ airship shed waitin' fo' you.&rdquo;
+ </p>
+ <p>
+ &ldquo;In the airship shed! No strangers are allowed in there, Rad.&rdquo;
+ </p>
+ <p>
+ &ldquo;I knows it, Massa Tom, but he done persisted his se'f inter it, an' he
+ wouldn't come out when I told him; an' your pa an' Mr. Jackson ain't
+ home.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll see about this,&rdquo; exclaimed Tom, striding to the large shed, where
+ the Red Cloud was kept. As he entered it he saw a man looking over the
+ wonderful craft.
+ </p>
+ <p>
+ &ldquo;Did you want to see me?&rdquo; asked Tom, sharply, for he did not like
+ strangers prowling around.
+ </p>
+ <p>
+ &ldquo;I did, and I apologize for entering here, but I am interested in
+ airships, and I thought you might want to hire a pilot. I am in need of
+ employment, and I have had considerable to do with balloons and
+ aeroplanes, but never with an airship like this, which combines the two
+ features. Do you wish to hire any one.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, I don't!&rdquo; replied Tom, sharply, for he did not like the looks of the
+ man.
+ </p>
+ <p>
+ &ldquo;I was told that you did,&rdquo; was the rather surprising answer.
+ </p>
+ <p>
+ &ldquo;Who told you?&rdquo;
+ </p>
+ <p>
+ The man looked all around the shed, before replying, as if fearful of
+ being overheard. Then, stepping close to Tom, he whispered:
+ </p>
+ <p>
+ &ldquo;Mr. Jenks told me!&rdquo;
+ </p>
+ <p>
+ &ldquo;Mr. Jenks?&rdquo; Tom could not conceal his astonishment.
+ </p>
+ <p>
+ &ldquo;Yes. Mr. Barcoe Jenks. But I did not come here to merely ask you for
+ employment. I would like to hire out to you, but the real object of my
+ visit was to say this to you.&rdquo;
+ </p>
+ <p>
+ The man approached still closer to Tom, and, in a lower voice, and one
+ that could scarcely be heard, he fairly hissed:
+ </p>
+ <p>
+ &ldquo;Don't go with Barcoe Jenks to seek the diamond makers!&rdquo;
+ </p>
+ <p>
+ Then, before Tom could put out a hand to detain him, had the lad so
+ wished, the man turned suddenly, and fairly ran from the shed.

+ <h2>
+ CHAPTER VI&mdash;MR. DAMON IS ON HAND
+ </h2>
+ <p>
+ The young inventor stood almost spellbound for a few moments. Then
+ recovering himself he made a dash for the door through which the
+ mysterious man had disappeared. Tom saw him sprinting down the road, and
+ was half-minded to take after him, but a cooler thought warned him that he
+ had better not.
+ </p>
+ <p>
+ &ldquo;He may be one of those men who are on Mr. Jenks' trail,&rdquo; reasoned Tom, in
+ which case it might not be altogether safe to attempt to stop him, and
+ make him explain. Or he may be a lunatic, and in that case it wouldn't be
+ altogether healthy to interfere with him.
+ </p>
+ <p>
+ &ldquo;I'll just let him go, and tell Mr. Jenks about him when he comes
+ to-night. But I must warn Rad never to let him in here again. He might
+ damage the airship.&rdquo;
+ </p>
+ <p>
+ Calling to the colored man, Tom pointed to the stranger, who was almost
+ out of sight down the road, and said earnestly:
+ </p>
+ <p>
+ &ldquo;Rad, do you see that fellow?&rdquo;
+ </p>
+ <p>
+ &ldquo;I sho do, Massa Tom, but I sorter has t' strain my eyes t' do it. He's
+ goin' laik my mule Boomerang does when he's comm' home t' dinnah.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's right, Rad. Well, never let that man set foot inside our fence
+ again! If he comes, and I'm home, call me. If I'm away, call dad or Mr.
+ Jackson, and if you're here alone, drive him away, somehow.&rdquo;
+ </p>
+ <p>
+ &ldquo;I will, Massa Tom!&rdquo; exclaimed the colored man, earnestly, &ldquo;an' if I can't
+ do it alone, I'll get Boomerang t' help. Once let dat ar' mule git his
+ heels on a pusson, an' dat pusson ain't goin' t' come bodderin' around any
+ mo'&mdash;that is, not right away.&rdquo;
+ </p>
+ <p>
+ &ldquo;I believe you, Rad. Well, keep a lookout for him, and don't let him in,&rdquo;
+ and with that Tom entered the house to think over matters. They were
+ beginning to assume an aspect he did not altogether like. Not that Tom was
+ afraid of danger, but he preferred to meet it in the open, and the
+ warning, or threat, of the mysterious man disquieted him.
+ </p>
+ <p>
+ When Mr. Swift came home, a little later, his son told him of the midnight
+ interview with Mr. Jenks, for, up to this time, the aged inventor was
+ unaware of it, and Tom also gave an account of the diamonds, speaking of
+ their value.
+ </p>
+ <p>
+ &ldquo;And do you propose to go to Phantom Mountain, in search of the makers of
+ these gems, Tom?&rdquo; asked Mr. Swift.
+ </p>
+ <p>
+ &ldquo;I had about decided to do so, dad.&rdquo;
+ </p>
+ <p>
+ &ldquo;And you're going in the Red Cloud?'
+ </p>
+ <p>
+ &ldquo;Yes.&rdquo;
+ </p>
+ <p>
+ &ldquo;Who are going with you?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, Mr. Jenks will go, of course, and I've no doubt but that if I
+ mention the prospective trip to Mr. Damon, that he'll bless his skating
+ cap, or something like that, and come along.&rdquo;
+ </p>
+ <p>
+ &ldquo;I suppose so, Tom, and I'd like to have you take him. But I think you'll
+ need some one else.&rdquo;
+ </p>
+ <p>
+ &ldquo;Because, from what you have told me, you are going out to a dangerous
+ part of the country, and you may have to deal with unscrupulous men. Three
+ of you are hardly enough to cope with them. You ought to have at least
+ another member of your party. If I was not busy on my invention of a new
+ wireless motor I would go along, but I can't leave. You might take Mr.
+ Jackson.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, you need him here to help you, dad.&rdquo;
+ </p>
+ <p>
+ &ldquo;How about Eradicate?&rdquo;
+ </p>
+ <p>
+ Tom smiled.
+ </p>
+ <p>
+ &ldquo;Rad would get homesick for his mule Boomerang, and I'd have to bring him
+ back just when we'd found the diamonds,&rdquo; replied the young inventor. &ldquo;No,
+ we'll have to think of some one else. I'll ask Mr. Damon, and then I'll
+ consider matters further. I expect to see Mr. Jenks to-night, and he may
+ have some one in mind.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps that will be a good plan. Well, Tom, I trust you will take good
+ care of yourself, and not run into unnecessary danger. Is the Red Cloud in
+ good shape for the voyage?&rdquo;
+ </p>
+ <p>
+ &ldquo;It needs looking over. I'm going to get right at it.&rdquo;
+ </p>
+ <p>
+ &ldquo;It's a pretty indefinite sort of a quest you're going on, Tom, my son.
+ How do you expect to find Phantom Mountain?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it's going to be quite a task. In the first place we'll head for
+ Leadville, Colorado, and then we'll go to Indian Ridge and make some
+ inquiries. We may get on the track of the place that way. If we don't, why
+ I'll take the airship up as high as is necessary and sort of prospect
+ until we see that big cliff that's shaped like a head. That will give us
+ something to go by.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, do the best you can. If you can discover the secret of making
+ diamonds it will be a valuable one.&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess it will, dad; and Mr. Jenks is entitled to know it, for he paid
+ his good money to that end. He has promised to go halves with me, as
+ payment for the use of the airship, and I must say the two diamonds he
+ gave me last night have proved very valuable.&rdquo;
+ </p>
+ <p>
+ &ldquo;Two diamonds, Tom? You only showed me one, an uncut gem;&rdquo; and Mr. Swift
+ looked at his son.
+ </p>
+ <p>
+ &ldquo;Oh, the other&mdash;er&mdash;the other is&mdash;I left it with a
+ jeweler,&rdquo; and Tom blushed a trifle, as he thought of the present he
+ contemplated making to Mary Nestor.
+ </p>
+ <p>
+ That afternoon, as Tom was out in the shed of the Red Cloud looking over
+ the airship, to see what would be necessary to do to it in order to get it
+ in shape for a long trip, he heard voices outside.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;yes, I know the way in perfectly well,&rdquo; he caught. &ldquo;You needn't
+ bother to come, my good fellow. Just step this way, and I'll show you
+ something worth seeing.&rdquo;
+ </p>
+ <p>
+ &ldquo;I wonder if it's that mysterious man coming back?&rdquo; thought Tom. He
+ dropped the tool he was using, and hurried to the door. As he approached
+ it he heard the voice continue.
+ </p>
+ <p>
+ &ldquo;Why bless my shoe laces, Mr. Parker! You'll see a wonderful airship, I
+ promise you. Wonderful! Bless my hatband, but I hope Tom is here!&rdquo;
+ </p>
+ <p>
+ &ldquo;Mr. Damon!&rdquo; exclaimed our hero, as he recognized the tones of his
+ eccentric friend. &ldquo;But who is with him?&rdquo;
+ </p>
+ <p>
+ A moment later he caught sight of the gentleman who was always blessing
+ himself, or something. Behind him stood another man, whose features Tom
+ could not see plainly.
+ </p>
+ <p>
+ &ldquo;Hello, Tom Swift!&rdquo; called Mr. Damon. &ldquo;Looking over the Red Cloud, eh?
+ Does that mean you're off on another trip?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess it does,&rdquo; answered the lad.
+ </p>
+ <p>
+ &ldquo;Where to this time? if I may ask.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm thinking of going off to the mountains to find a band of men engaged
+ in making diamonds,&rdquo; replied Tom.
+ </p>
+ <p>
+ &ldquo;Making diamonds! Bless my finger ring! Making diamonds! A trip to the
+ mountains! Bless my disposition! but do you know I'd like to go with you!&rdquo;
+ </p>
+ <p>
+ &ldquo;I was thinking of asking you, Mr. Damon.&rdquo;
+ </p>
+ <p>
+ &ldquo;Were you? Bless my heart, I'm glad you thought of me. You don't by any
+ possible chance want another person; do you?&rdquo;
+ </p>
+ <p>
+ &ldquo;We were thinking of having four in the party, Mr. Damon,&rdquo; and Tom
+ wondered who was with his eccentric friend.
+ </p>
+ <p>
+ &ldquo;Then bless my election ticket! This is the very chance for you, Mr.
+ Parker!&rdquo; cried Mr. Damon. &ldquo;Will you go with us? It will be just what you
+ need,&rdquo; and Mr. Damon stepped aside, revealing to Tom the features of Mr.
+ Ralph Parker, the scientist who had correctly predicted the destruction of
+ Earthquake Island.

+ <h2>
+ CHAPTER VII&mdash;MR. PARKER PREDICTS
+ </h2>
+ <p>
+ Tom Swift was a most generous lad, but when he saw that Mr. Damon had with
+ him Mr. Parker, the gloomy scientist, who seemed to take delight in
+ predicting disasters, our hero's spirits were not exactly of the best. He
+ would have much preferred not to take Mr. Parker on the quest for the
+ diamond makers, but, since Mr. Damon had mentioned it, he did not see how
+ he could very well refuse.
+ </p>
+ <p>
+ &ldquo;But perhaps he won't care to go,&rdquo; thought Tom.
+ </p>
+ <p>
+ He was undeceived a moment later, however, for the scientist remarked:
+ </p>
+ <p>
+ I am very glad to meet you once more, Mr. Swift. I have scarcely thanked
+ you enough for what you did for us in erecting your wireless station on
+ Earthquake Island, which, as you recall, I predicted would sink into the
+ sea. It did, I am glad to say, not because I like to see islands
+ destroyed, but because science has been vindicated. Now I have just heard
+ you remark that you are about to set off to the mountains in search of
+ some men who are making diamonds. I need hardly state that this is utterly
+ useless, for no diamonds, commercially valuable, can be made by men. But
+ the trip may be valuable in that it will permit me to demonstrate some
+ scientific facts.
+ </p>
+ <p>
+ &ldquo;Therefore, if you will permit me, I will be very glad to accompany you
+ and Mr. Damon. I shall be delighted, in short, and I can start as soon as
+ you are ready.&rdquo;
+ </p>
+ <p>
+ &ldquo;There's no hope for it!&rdquo; thought Tom, dismally. &ldquo;I suppose he'll wake up
+ every morning, and predict that before night the world will come to an
+ end, or he'll prophesy that the airship will blow up, and vanish, when
+ about seven miles above the clouds. Well, there's no way out of it, so
+ here goes.&rdquo;
+ </p>
+ <p>
+ Thereupon Tom welcomed the scientist as cordially as he could, and invited
+ him to form one of the party that would set off in the airship to search
+ for Phantom Mountain.
+ </p>
+ <p>
+ &ldquo;Bless my jewelry box!&rdquo; exclaimed Mr. Damon, when this formality was over.
+ &ldquo;Tell me more about it, Tom.&rdquo;
+ </p>
+ <p>
+ Which our hero did, stating the need of maintaining secrecy on account of
+ the danger to Mr. Jenks. Mr. Damon and Mr. Parker both agreed to say
+ nothing about the matter, and then the scientist became much interested in
+ the Red Cloud, which he closely examined. He even complimented Tom on the
+ skill shown in making it, and, contrary to our hero's expectation, did not
+ predict that it would blow up the next time it was used.
+ </p>
+ <p>
+ &ldquo;How did you happen to arrive just at this time, Mr. Damon?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;It was partly due to Mr. Parker,&rdquo; was the answer. &ldquo;I had not seen him
+ since we were rescued from the island, until a few days ago he called on
+ me at my home. I happened to mention that you lived near here, and
+ suggested that he might like to see some of your inventions. He agreed,
+ and we came over in my auto. And now, bless my liver-pin! I find you about
+ to start off on another trip.&rdquo;
+ </p>
+ <p>
+ &ldquo;And have you fully decided to go with me?&rdquo; asked Tom. &ldquo;There may be
+ danger, and I don't like the way that mysterious man behaved.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, bless my revolver!&rdquo; cried Mr. Damon. &ldquo;I'm used to danger by this
+ time. Of course I'm going, and so is Mr. Parker. Do you know,&rdquo; and the
+ man, who was always blessing something, came closer to the lad, and
+ whispered: &ldquo;Do you know, Tom, Mr. Parker is a very peculiar individual.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm sure of it,&rdquo; answered the young inventor, looking at the gentleman in
+ question, who was then inside the airship cabin.
+ </p>
+ <p>
+ &ldquo;But he's all right, even if he is predicting unpleasant things,&rdquo; went on
+ Mr. Damon. &ldquo;I think we'll get better acquainted with him after a bit.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope so,&rdquo; agreed Tom, but he did not realize then how close his
+ companionship with Mr. Parker was to be, nor what dangers they were to
+ share later.
+ </p>
+ <p>
+ The friends talked at considerable length of the prospective trip, and
+ Tom, by this time, had ascertained what needed to be done to the airship
+ to get it in shape to travel. It would take about a week, and, in the
+ meanwhile, Mr. Damon would go home and get his affairs in order for the
+ voyage. Tom's father was introduced to Mr. Parker, and, the former,
+ finding that the scientist held some views in common with him, invited the
+ gloomy predictor to remain at the Swift home until the Red Cloud was ready
+ to sail. Tom could not repress a groan at this, but he decided he would
+ have to make the best of it.
+ </p>
+ <p>
+ Mr. Damon left for home that afternoon, promising to be on hand at the
+ time set to start for Phantom Mountain.
+ </p>
+ <p>
+ Tom was up waiting for Mr. Jenks at twelve o'clock that night. Shortly
+ after the hour he saw a dark figure steal into the orchard. At first he
+ feared lest it might be one of the spies who were, he was now convinced,
+ on the trail of the man who was seeking to discover the secret of the
+ diamond makers. But a whistle, which came to the lad's ear a moment later
+ (that being a signal Mr. Jenks had agreed to sound), told Tom that it was
+ none other than the visitor he expected.
+ </p>
+ <p>
+ &ldquo;All right, Mr. Jenks, I'm here,&rdquo; called Tom, cautiously. &ldquo;Come over this
+ way,&rdquo; and he went out from the shadow of the house, where he had been
+ waiting, and met the men. &ldquo;We'll go into my private work-shop,&rdquo; the youth
+ added, leading the way.
+ </p>
+ <p>
+ &ldquo;Have you decided to go with me?&rdquo; asked Mr. Jenks, in an anxious whisper.
+ &ldquo;Did you find the diamonds to be real ones?&rdquo;
+ </p>
+ <p>
+ &ldquo;I did; and I'm going,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;Good! That relieves my mind. But we are still in danger. I was followed
+ by my shadower to-day, and only succeeded in shaking him off just before
+ coming here. I don't believe he knows what I am about to do.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, yes he does,&rdquo; said Tom.
+ </p>
+ <p>
+ &ldquo;He does? How?&rdquo;
+ </p>
+ <p>
+ &ldquo;Because he was here, and warned me against you!&rdquo;
+ </p>
+ <p>
+ &ldquo;You don't mean it! Well, they are getting desperate! We must be on our
+ guard. What sort of a man was he?&rdquo;
+ </p>
+ <p>
+ Tom described the fellow, and Mr. Jenks stated that this tallied with the
+ appearance of the person who had been shadowing him.
+ </p>
+ <p>
+ &ldquo;But we'll fool them yet!&rdquo; cried Tom, who had now fully entered into the
+ spirit of the affair. &ldquo;If they can follow us in the Red Cloud they're
+ welcome to. I think we'll get ahead of them.&rdquo;
+ </p>
+ <p>
+ He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed that it
+ would add to the strength of the party to take these two gentlemen along.
+ </p>
+ <p>
+ &ldquo;Though I can't say I care so much for Mr. Parker,&rdquo; he added. &ldquo;But now as
+ to ways and means. When can we start?&rdquo;
+ </p>
+ <p>
+ Thereupon he and Tom talked over details in the seclusion of the little
+ office, and arranged to leave Shopton in about a week. In the meanwhile
+ the airship would be overhauled, stocked with supplies and provisions, and
+ be made ready for a swift dash to the mountains.
+ </p>
+ <p>
+ &ldquo;And now I must be going,&rdquo; said Mr. Jenks. &ldquo;I have a great deal to do
+ before I can start on this trip, and I hope I am not prevented by any of
+ those men who seem to be trailing me.&rdquo;
+ </p>
+ <p>
+ &ldquo;How could they prevent you?&rdquo; Tom wanted to know.
+ </p>
+ <p>
+ &ldquo;Oh, there are any number of ways,&rdquo; was the answer. &ldquo;But I'm glad you
+ found that my diamonds were real. We'll soon have plenty, if all goes
+ well.&rdquo;
+ </p>
+ <p>
+ As Mr. Jenks left the shop, he started back, in some alarm.
+ </p>
+ <p>
+ &ldquo;What's the matter?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Over there&mdash;I thought I saw a figure sneaking along under the trees&mdash;that
+ man&mdash;perhaps&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;That's Eradicate, our colored helper,&rdquo; replied Tom, with a laugh. &ldquo;I
+ posted him there to see that no strangers came into the orchard.
+ Everything all right, Rad?&rdquo; he asked, raising his voice.
+ </p>
+ <p>
+ &ldquo;Yais, sah, Massa Tom. Nobody been around yeah this night.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's good. You can go to bed now,&rdquo; and Eradicate, yawning loudly, went
+ to his shack. A little later Tom sought his own room, Mr. Jenks having
+ hurried off to town, where he was boarding.
+ </p>
+ <p>
+ The next few days saw Tom busily engaged on the airship, making some
+ changes and a few repairs that were needed. His father, Eradicate and Mr.
+ Jackson helped him. As for Mr. Parker, the scientist, he went about the
+ place, being much interested in the various machines which Tom or Mr.
+ Swift had patented.
+ </p>
+ <p>
+ At other times the scientist would stroll about the extensive grounds,
+ making what he said were &ldquo;observations.&rdquo; One afternoon Tom saw him,
+ apparently much excited, kneeling down back of a shed, with his ear to the
+ ground.
+ </p>
+ <p>
+ &ldquo;What is the matter?&rdquo; asked the lad, thinking perhaps Mr. Parker might be
+ ill.
+ </p>
+ <p>
+ &ldquo;Have you ever had any earthquakes here, Tom Swift?&rdquo; asked the scientist,
+ quietly.
+ </p>
+ <p>
+ &ldquo;Earthquakes? No. We had enough of them on the island.&rdquo;
+ </p>
+ <p>
+ &ldquo;And you are going to have one here, in about two minutes!&rdquo; cried Mr.
+ Parker. &ldquo;I predict that this place will be shaken by a tremendous shock
+ very soon. We had all better get away from the vicinity of buildings.&rdquo;
+ </p>
+ <p>
+ &ldquo;What makes you think there will be an earthquake?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Because I can hear the rumbling beneath the ground at this very minute.
+ It is increasing in volume, showing that the tremors are working this way.
+ There will soon be a great subterranean upheaval! Listen for yourself.&rdquo;
+ </p>
+ <p>
+ Tom cast himself down on the grass. Placing his ear close to the ground he
+ did hear a series of dull thuds. He arose, not a little alarmed. There had
+ never been any earthquakes in Shopton, yet he had great respect for Mr.
+ Parker's scientific attainments.
+ </p>
+ <p>
+ Just then Eradicate Sampson came along. He saw Tom and Mr. Parker lying
+ flat on the ground, and surprise showed on his honest, black face.
+ </p>
+ <p>
+ &ldquo;Fo' de land sakes!&rdquo; cried Eradicate. &ldquo;What am de mattah now, Massa Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Earthquake coming,&rdquo; answered Tom, briefly. &ldquo;Better get away from the
+ buildings, Rad. They might fall!&rdquo; Tom's face showed the alarm he felt.
+ What would happen to all of his valuable machines&mdash;to the Red Cloud?
+ </p>
+ <p>
+ &ldquo;Earthquake?&rdquo; murmured Eradicate, and he, too, cast himself down to
+ listen. A moment later he arose with a laugh.
+ </p>
+ <p>
+ &ldquo;What's the matter?&rdquo; cried Tom.
+ </p>
+ <p>
+ &ldquo;Why, dat ain't no earthquake!&rdquo; declared the colored man.
+ </p>
+ <p>
+ &ldquo;No. Then perhaps you know what it is,&rdquo; said Mr. Parker, somewhat sharply.
+ </p>
+ <p>
+ &ldquo;Course I knows what it am,&rdquo; answered Eradicate, with dignity. &ldquo;Dat noise
+ am my mule Boomerang, kickin' in his stable, on account oh me not feedin'
+ him yet. Dat's what it am. I'se gwine right now t' gib him his oats, and
+ den yo' see dat de noise stop. Boomerang allers kick dat way when he's
+ hungry. I show yo'!&rdquo;
+ </p>
+ <p>
+ And, sure enough, when Eradicate had gone to the mule's stable, which was
+ near where Mr. Parker had heard the mysterious sounds, they immediately
+ ceased.
+ </p>
+ <p>
+ &ldquo;Dat mule was all de earthquake dere was around here,&rdquo; said the colored
+ man as he came out.
+ </p>
+ <p>
+ Mr. Parker walked away, saying nothing, and Tom did not make any comments&mdash;just
+ then.

+ <h2>
+ CHAPTER VIII&mdash;OFF FOR THE WEST
+ </h2>
+ <p>
+ It was a great relief to Tom, to find that there was no danger from an
+ earth tremor. Now that he had made up his mind to go in search of the
+ diamond makers, he wanted nothing to interfere with it. Lest the feelings
+ of Mr. Parker might be hurt by the mistake he had made, the young inventor
+ cautioned Eradicate not to say anything more about the matter.
+ </p>
+ <p>
+ &ldquo;'Deed an' I won't,&rdquo; the colored man promised. &ldquo;I'se only too glad dere
+ wa'n't no earthquake, dat's what I is.&rdquo;
+ </p>
+ <p>
+ As for Mr. Parker, he did not appear much put out by his error in
+ predicting.
+ </p>
+ <p>
+ &ldquo;I am sure that what I heard was a tremor, due to some distant earthquake
+ shock,&rdquo; he said. &ldquo;The mule's kicking was only a coincidence.&rdquo;
+ </p>
+ <p>
+ And Tom let him have his way about it. The week was drawing to a close,
+ and the Red Cloud was nearly in shape for the voyage. At almost the last
+ minute Tom found that he needed some electrical apparatus for the airship,
+ and as he had to go to Chester for it, he decided he would make the trip
+ in his monoplane, and, while in the city, would also get the diamond pin
+ he was having made for Mary Nestor.
+ </p>
+ <p>
+ He started off early one morning, in the swift little craft Butterfly, and
+ soon had reached Chester. The diamond brooch was ready for him.
+ </p>
+ <p>
+ &ldquo;It is one of the most beautiful stones we have ever set,&rdquo; the diamond
+ merchant told him. &ldquo;Don't forget, if you find any more, Mr. Swift, to let
+ us have a chance to bid on them.&rdquo;
+ </p>
+ <p>
+ &ldquo;I may,&rdquo; Tom promised, rather indefinitely. Then, having purchased his
+ electrical supplies, he made a quick trip to Shopton, stopping on the way
+ to call on Miss Nestor.
+ </p>
+ <p>
+ &ldquo;Why Tom, I'm delighted to see you!&rdquo; cried the girl, blushing prettily.
+ &ldquo;Did you come for some apple turnovers?&rdquo; and she laughed, as she referred
+ to a call Tom had once paid, when a new cook had been engaged, and when
+ the pastry formed a feature of the meal.
+ </p>
+ <p>
+ &ldquo;No turnovers this time,&rdquo; said the young inventor. &ldquo;I came to wish you
+ many happy returns of the day.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, you remembered my birthday! How nice of you!&rdquo;
+ </p>
+ <p>
+ &ldquo;And here is something else,&rdquo; added our hero, rather awkwardly, as he
+ handed her the diamond pin.
+ </p>
+ <p>
+ &ldquo;Oh, Tom! This for me! Oh, it's too lovely&mdash;it's far too much!&rdquo;
+ </p>
+ <p>
+ &ldquo;It isn't half enough!&rdquo; he declared, warmly.
+ </p>
+ <p>
+ &ldquo;Oh, what a large diamond!&rdquo; Mary cried as she saw the sparkling stone. &ldquo;I
+ never saw one so large and beautiful!&rdquo;
+ </p>
+ <p>
+ &ldquo;It's just as easy to make them large as small,&rdquo; explained Tom.
+ </p>
+ <p>
+ &ldquo;Make them?&rdquo; she looked the surprise she felt.
+ </p>
+ <p>
+ &ldquo;Yes, I'm about to start for the place where diamonds are made.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, Tom! But isn't it dangerous? I mean won't you have to go to some far
+ country&mdash;like Africa&mdash;to get to where diamonds are made?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, we are going on quite a trip, but not as far as that. And as for
+ the danger&mdash;well, we'll have to take what comes,&rdquo; and he told her
+ something of the proposed quest.
+ </p>
+ <p>
+ &ldquo;Oh, it sounds&mdash;sounds scary!&rdquo; Mary exclaimed, when she had heard of
+ Mr. Jenks' experience. &ldquo;Do be careful, Tom!&rdquo;
+ </p>
+ <p>
+ &ldquo;I will,&rdquo; he promised, and, somehow he was glad that she had cautioned him
+ thus&mdash;and in such tones as she had used. For Mary Nestor was a girl
+ that any young chap would have been glad to have manifest an interest in
+ him.
+ </p>
+ <p>
+ &ldquo;Well, I guess I'll have to say good-by,&rdquo; spoke Tom, at length. &ldquo;We expect
+ to start in a couple of days, and I may not get another chance to see
+ you.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I&mdash;I hope you come back safely,&rdquo; faltered Mary, and then she
+ held out her hand, and Tom&mdash;well, it's none of our affair what Tom
+ did after that, except to say that he hurried out, fairly jumped into his
+ monoplane, and completed the trip home.
+ </p>
+ <p>
+ As the Red Cloud has been fully described in the volume entitled &ldquo;Tom
+ Swift and His Airship,&rdquo; we will not go into details about it now.
+ Sufficient to say that it was a combination of a biplane and dirigible
+ balloon. It could be used either as one or the other, and the gas-bag
+ feature was of value when the wind was too great to allow the use of the
+ planes, or when the motive power, for some reason stopped. In that event
+ the airship could remain suspended far above the clouds if necessary.
+ There was provision for manufacturing the gas on board.
+ </p>
+ <p>
+ The Red Cloud was fitted up to accommodate about ten persons, though it
+ was seldom that this number was carried. Two persons could successfully
+ operate the machinery. There were sleeping berths, and in the main cabin a
+ sitting-room, a dining-room, and a kitchen. There was also the motor
+ compartment, and a steering tower, from which the engines could be
+ controlled.
+ </p>
+ <p>
+ It was in this craft that the seekers after the diamond makers proposed
+ undertaking the trip. Mr. Damon came on from his home in Waterfield about
+ two days before the date set to leave, and Mr. Jenks, had, three days
+ before this, taken up his abode at the Swift home. Mr. Parker, as has been
+ stated, was already there, and he had put in his time making a number of
+ scientific observations, though he had made no more predictions.
+ </p>
+ <p>
+ Nothing more had been seen of the mysterious man who had warned Tom, and
+ the young inventor and Mr. Jenks began to hope that they had thrown their
+ enemies off the track.
+ </p>
+ <p>
+ &ldquo;Though I don't imagine they'll give up altogether,&rdquo; said Mr. Jenks.
+ &ldquo;They're too desperate for that. We'll have trouble with them yet.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it can't be helped,&rdquo; decided Tom. &ldquo;We'll try and be ready for it,
+ when it comes,&rdquo; and then, dismissing the matter from his mind, he busied
+ himself about the airship.
+ </p>
+ <p>
+ The food and supplies had all been put aboard, and they expected to start
+ the next morning. In order to make sure that any stones which they might
+ succeed in getting from the diamond makers were real gems, a set of
+ testing apparatus was taken along. Mr. Parker had had some experience in
+ this line, and, in spite of the fact that he might make direful
+ predictions, Tom was rather glad, after all, that the scientist was going
+ to accompany them.
+ </p>
+ <p>
+ &ldquo;But what is worrying me,&rdquo; said Mr. Damon, &ldquo;is what we are going to do
+ after we get to Phantom Mountain. What are your plans, Mr. Jenks? Will you
+ go in, and demand your share of the diamond-making business?&rdquo;
+ </p>
+ <p>
+ &ldquo;I have a right to it, as I invested a large sum in it, and I am entitled
+ to more than a half-share. But, of course, I can't say what I'll do until
+ I get there. We may have to act very secretly.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm inclined to think we will,&rdquo; said Tom. &ldquo;My plan would be to gain
+ access to the cave, if possible, and watch them at work. We might be able
+ to discover the secret of making diamonds, and, after all, that's what you
+ want, isn't it, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, I paid my money for the secret, and I ought to have it. If I can get
+ it quietly, so much the better. If not, I'll fight for my rights!&rdquo; and he
+ looked very determined.
+ </p>
+ <p>
+ &ldquo;Bless my powder horn!&rdquo; cried Mr. Damon. &ldquo;That's the way to talk! And so
+ we're to go cruising about in the air, looking for a mountain shaped like
+ a man's head.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's it,&rdquo; agreed Mr. Jenks, &ldquo;and when we find it we will be near
+ Phantom Mountain, and the diamond makers.&rdquo;
+ </p>
+ <p>
+ The final details were completed that night. The last of the supplies had
+ been put aboard, the larder was well stocked, the diamond testing
+ apparatus was stored safely away, and all that remained was for the
+ adventurers to board the Red Cloud in the morning, and soar away.
+ </p>
+ <p>
+ That night Tom was uneasy. Several times he got up, and looked toward the
+ shed where the airship was stored. He could not rid himself of the idea
+ that the men to whose interest it was that the diamond-making secret
+ remain undiscovered, might attempt to wreck the airship before the start.
+ Consequently both Eradicate Sampson and Engineer Jackson were on guard.
+ Tom looked from his window, to the shed where the Red Cloud was housed. He
+ saw nothing to cause him any uneasiness.
+ </p>
+ <p>
+ &ldquo;I guess I'm just nervous,&rdquo; he mused. &ldquo;But, all the same, I'll be glad
+ when we've started.&rdquo;
+ </p>
+ <p>
+ They were all up early the next morning, Mr. Damon beginning the day by
+ blessing the sunrise, and many other things that struck his fancy. The
+ airship was wheeled out of the shed, and Tom gave her a final inspection.
+ </p>
+ <p>
+ &ldquo;It's all right,&rdquo; he declared. &ldquo;All aboard!&rdquo;
+ </p>
+ <p>
+ &ldquo;Now, do be careful,&rdquo; begged Mr. Swift. &ldquo;Don't take too many chances,
+ Tom.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'll not.&rdquo;
+ </p>
+ <p>
+ The adventurers were in the forward part of the ship, and Tom had taken
+ his place at the wheels and levers in the pilot house. As he was about to
+ start the motor he looked toward the road, and saw a horse and carriage.
+ In the vehicle was a girlish figure, at the sight of which Tom blushed and
+ smiled. He waved his hand.
+ </p>
+ <p>
+ &ldquo;I came to wish you good luck!&rdquo; cried Mary Nestor, for it was she in the
+ carriage.
+ </p>
+ <p>
+ &ldquo;Thanks!&rdquo; cried Tom, leaning from the window of the pilot house. &ldquo;It was
+ good of you to get up so early.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh. I'm always up early,&rdquo; she informed him.
+ </p>
+ <p>
+ &ldquo;Look out that the motor doesn't scare your horse,&rdquo; Tom warned her.
+ </p>
+ <p>
+ &ldquo;Old Dobbin doesn't mind anything,&rdquo; was her answer. &ldquo;I'll see that he
+ doesn't run away with me, as long as you're not on earth to rescue me.
+ Good-by, Tom!&rdquo;
+ </p>
+ <p>
+ &ldquo;Good-by!&rdquo; he called, and then he pulled the lever that set in motion the
+ motor, and whirled the great propellers about. They whizzed around with a
+ roar, and the Red Cloud, shivering and trembling with the vibration, rose
+ in the air like some great bird.
+ </p>
+ <p>
+ &ldquo;We're off for the West and Phantom Mountain!&rdquo; called Tom to his
+ companions.
+ </p>
+ <p>
+ As the airship soared upward, Eradicate Sampson ran forward from where he
+ had been standing near his mule Boomerang. He waved his hands, and shouted
+ something.
+ </p>
+ <p>
+ &ldquo;Bless my hatband! What does he want?&rdquo; asked Mr. Damon, watching him
+ curiously.
+ </p>
+ <p>
+ &ldquo;It sounds as if he were calling to us to come back,&rdquo; spoke Mr. Parker.
+ </p>
+ <p>
+ &ldquo;It's too late now,&rdquo; decided Tom. &ldquo;Maybe he forgot to tell us good-by,&rdquo;
+ but, he felt a vague wonder at Eradicate's odd motions; for the colored
+ man was pointing toward the stern of the airship, as if there was
+ something wrong there. But the Red Cloud soared on.

+ <h2>
+ CHAPTER IX&mdash;A WARNING BY WIRELESS
+ </h2>
+ <p>
+ Rapidly the airship ascended, and, when it was high over the town of
+ Shopton, Tom headed the craft due west. Looking down he tried to descry
+ Mary Nestor, in her carriage, but the trees were in the way, their
+ interlocking branches hiding the girl. Tom did see crowds of other
+ persons, though, thronging the streets of Shopton, for, though the young
+ inventor had made many flights, there was always a novelty about them,
+ that brought out the curious.
+ </p>
+ <p>
+ &ldquo;A good start, Tom Swift,&rdquo; complimented Mr. Parker. &ldquo;Is it always as easy
+ as this?&rdquo;
+ </p>
+ <p>
+ &ldquo;Starting always is,&rdquo; was the answer, &ldquo;though, as the Irishman said,
+ coming down isn't sometimes quite so comfortable.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my gizzard! That's so,&rdquo; cried the eccentric Mr. Damon. &ldquo;Can we
+ vol-plane to earth in the Red Cloud, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, but not as easily as in the Butterfly. However I hope we will not
+ have to. Now, Mr. Damon, if you will just take charge of the steering
+ apparatus for a minute, I want to go aft.&rdquo;
+ </p>
+ <p>
+ &ldquo;What for?&rdquo;
+ </p>
+ <p>
+ &ldquo;I wish to see if everything is all right. I can't imagine why Eradicate
+ was making those queer motions.&rdquo;
+ </p>
+ <p>
+ Mr. Damon, who knew how to operate the Red Cloud, was soon guiding her on
+ the course, while Tom made his way to the rear compartments, through the
+ motor room, where the stores of supplies and food were kept. He made a
+ careful examination, looking from an after window, and even going out on a
+ small, open platform, but could discover nothing wrong.
+ </p>
+ <p>
+ &ldquo;I guess Rad was just capering about without any special object,&rdquo; mused
+ Tom, but it was not long after this that they learned to their dismay,
+ that the colored man had had a method in his madness.
+ </p>
+ <p>
+ On his way back through the motor room Tom looked to the machinery, and
+ adjusted some of the auxiliary oil feeders. The various pieces of
+ apparatus were working well, though the engine had not yet been speeded up
+ to its limit. Tom wanted it to &ldquo;warm-up&rdquo; first.
+ </p>
+ <p>
+ &ldquo;Everything all right?&rdquo; asked Mr. Damon, as Tom rejoined them in the pilot
+ house, which was just forward of the living room in the main cabin.
+ </p>
+ <p>
+ &ldquo;Yes, I can't imagine what made Rad act that way. But I'll set the
+ automatic steering gear now, Mr. Damon, and then you will be relieved.&rdquo;
+ </p>
+ <p>
+ Mr. Jenks was gazing off toward the west&mdash;to where he hoped to
+ discover the secret of Phantom Mountain.
+ </p>
+ <p>
+ &ldquo;How do you like it?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;It's great,&rdquo; replied the diamond man. &ldquo;I've never been in an airship
+ before, and it's different than what I expected; but it's great! It's the
+ only craft that will serve our purpose among the towering mountain peaks,
+ where the diamond makers are hidden. I hope we can find them.&rdquo;
+ </p>
+ <p>
+ In a little while the Red Cloud was skimming along at faster speed, guided
+ by the automatic rudders, so that no one was needed in the pilot house,
+ since there was no danger of collisions. Airships are not quite numerous
+ enough for that, yet, though they may soon become so.
+ </p>
+ <p>
+ Tom and the others devoted several hours to arranging their staterooms and
+ bunks, and getting their clothing stowed away, and when this was done Mr.
+ Parker and Mr. Jenks sat gazing off into space.
+ </p>
+ <p>
+ &ldquo;It's hard to realize that we are really in an airship,&rdquo; observed the
+ diamond man. &ldquo;At first I thought I would be frightened, but I'm not a bit.
+ It doesn't seem as if anything could happen.&rdquo;
+ </p>
+ <p>
+ &ldquo;Something is likely to happen soon,&rdquo; said Mr. Parker, suddenly, as he
+ gazed at some weather instruments on the cabin wall.
+ </p>
+ <p>
+ &ldquo;Bless my soul! Don't say that!&rdquo; cried Mr. Damon. &ldquo;What is it?&rdquo;
+ </p>
+ <p>
+ &ldquo;I think, from my observations, that we will soon have a hurricane,&rdquo; said
+ the scientific man. &ldquo;There is every indication of it;&rdquo; and he seemed quite
+ delighted at the prospect of his prediction coming true.
+ </p>
+ <p>
+ &ldquo;A hurricane!&rdquo; cried Mr. Damon. &ldquo;I hope it isn't like the one that blew us
+ to Earthquake Island.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I think there will be no danger,&rdquo; spoke Tom. &ldquo;If it comes on to blow
+ we will ascend or descend out of the path of the storm. This craft is not
+ like the ill-fated Whizzer. I can more easily handle the Red Cloud; even
+ in a bad storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm glad to hear that,&rdquo; remarked Mr. Jenks. &ldquo;It would be too bad to be
+ wrecked before we got to Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I predict that we will have a bad storm,&rdquo; insisted Mr. Parker, and
+ Tom could not help wishing that the scientist would keep his gloomy
+ forebodings to himself.
+ </p>
+ <p>
+ However the storm had not developed up to noon, when Tom, with Mr. Damon's
+ help, served a fine meal in the dining-room. In the afternoon the speed of
+ the ship was increased, and by night they had covered several hundred
+ miles. Through the darkness the Red Cloud kept on, making good time. Tom
+ got up, occasionally, to look to the machinery, but it was all
+ automatically controlled, and an alarm bell would sound in his stateroom
+ when anything went wrong.
+ </p>
+ <p>
+ &ldquo;Bless my napkin!&rdquo; exclaimed Mr. Damon the next morning, as they sat down
+ to a breakfast of fruit, ham and eggs and fragrant coffee, &ldquo;this is living
+ as well as in a hotel, and yet we are&mdash;how far are we above the
+ earth, Tom?&rdquo; he asked, turning to the young inventor.
+ </p>
+ <p>
+ &ldquo;About two miles now. I just sent her up, as I thought I detected that
+ storm Mr. Parker spoke of.&rdquo;
+ </p>
+ <p>
+ &ldquo;I told you it would come,&rdquo; declared the scientist, and there was a small
+ hurricane below them that morning, but only the lower edge of it caught
+ the Red Cloud, and when Tom sent her up still higher she found a
+ comparatively quiet zone, where she slid along at good speed.
+ </p>
+ <p>
+ That afternoon Tom busied himself about some wires and a number of
+ complicated pieces of apparatus which were in one corner of the main
+ cabin.
+ </p>
+ <p>
+ &ldquo;What are you doing now?&rdquo; asked Mr. Jenks, who had been talking with Mr.
+ Parker, and showing that scientist some of the manufactured diamonds.
+ </p>
+ <p>
+ &ldquo;Getting our wireless apparatus in shape,&rdquo; answered the lad. &ldquo;I should
+ have done it before, but I had so much to do that I couldn't get at it.
+ I'm going to send off some messages. Dad will want to know how we are
+ doing.&rdquo;
+ </p>
+ <p>
+ As he worked away, he also made up his mind to send another message, in
+ care of his father, for there was a receiving station in the Swift home.
+ And to whom this message was addressed Tom did not say, but we fancy some
+ of our readers can guess.
+ </p>
+ <p>
+ Finally, after several hours of work, the wireless was in shape to send
+ and receive messages. Tom pulled over the lever, and a crackling sound was
+ heard, as the electricity leaped from the transmitters into space. Then he
+ clamped the receiver on his ear.
+ </p>
+ <p>
+ &ldquo;All ready,&rdquo; he announced. &ldquo;Has anybody any messages they wish sent?&rdquo; For,
+ with the courtesy of a true host he was ready to serve his guests before
+ he forwarded his own wireless notes.
+ </p>
+ <p>
+ &ldquo;Just tell my wife that I'm enjoying myself,&rdquo; requested Mr. Damon. &ldquo;Bless
+ my footstool! But this is great! We're off the earth yet, connected with
+ it.&rdquo;
+ </p>
+ <p>
+ Mr. Jenks had no one to whom he wanted to send any word, but Mr. Parker
+ wish to wire to a fellow scientist the result of some observations made in
+ the upper air.
+ </p>
+ <p>
+ Tom noted all the messages down, and then, when all was in readiness he
+ began to call his home station. He knew that either his father or Mr.
+ Jackson, the engineer, could receive the wireless.
+ </p>
+ <p>
+ But, no sooner had the young inventor sent off the first few dots and
+ dashes representing &ldquo;S. I.&rdquo;&mdash;his home station call&mdash;than he
+ started and a look of surprise came over his face.
+ </p>
+ <p>
+ &ldquo;They're calling us!&rdquo; he exclaimed.
+ </p>
+ <p>
+ &ldquo;Who is?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;My house&mdash;my father. He&mdash;he's been trying to get us ever since
+ we started, but I didn't have the wireless in shape to receive messages.
+ Oh, I hope it's not too late!&rdquo;
+ </p>
+ <p>
+ &ldquo;Too late! Bless my soul, too late for what?&rdquo; gasped Mr. Damon, somewhat
+ alarmed by Tom's manner.
+ </p>
+ <p>
+ The lad did not answer at once. He was intently listening to a series of
+ dots and dashes that clicked in the telephone receiver clamped to his left
+ ear. On his face there was a look of worriment.
+ </p>
+ <p>
+ &ldquo;Father has just sent me a message,&rdquo; he said. &ldquo;It's a warning flashed
+ through space! He's been trying to get it to me since yesterday!&rdquo;
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; asked Mr. Jenks, rising from his seat.
+ </p>
+ <p>
+ &ldquo;The mysterious man is aboard the airship&mdash;hidden away!&rdquo; cried Tom.
+ &ldquo;That's what Eradicate was trying to call to our attention as we started
+ off. Eradicate saw his face at a rear window, and tried to warn us! The
+ mysterious man is a stowaway on board!&rdquo;

+ <h2>
+ CHAPTER X&mdash;DROPPING THE STOWAWAY
+ </h2>
+ <p>
+ Tom's excited announcement startled Mr. Damon and the others as much as if
+ the young inventor had informed them that the airship had exploded and was
+ about to dash with them to the earth. The men leaped to their feet, and
+ stared at the lad.
+ </p>
+ <p>
+ &ldquo;A stowaway on board!&rdquo; cried Mr. Damon. &ldquo;Bless my soul! How did he&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;Are you sure that message is straight?&rdquo; asked Mr. Jenks. &ldquo;Did Eradicate
+ see the man?&rdquo;
+ </p>
+ <p>
+ &ldquo;He says he did,&rdquo; answered Tom. &ldquo;The man is hidden away on board now&mdash;probably
+ among the stores and supplies.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my tomato sauce!&rdquo; exploded Mr. Damon. &ldquo;I hope he doesn't eat them
+ all up!&rdquo;
+ </p>
+ <p>
+ &ldquo;We must get him out at once!&rdquo; declared Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I knew something would happen on this voyage,&rdquo; came from Mr. Parker. &ldquo;I
+ predicted it from the first!&rdquo;
+ </p>
+ <p>
+ Tom thought considerable, but he did not answer the scientist just then.
+ Another communication was coming to him by wireless. He listened intently.
+ </p>
+ <p>
+ &ldquo;Father says,&rdquo; the lad told his companions &ldquo;that Eradicate only had a
+ glimpse of the man at the last moment. He was looking from the rear
+ storeroom window&mdash;he's the same man who called on me that time&mdash;Rad
+ remembers him very well.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my shoes! What's to be done?&rdquo; inquired Mr. Damon, looking around
+ helplessly.
+ </p>
+ <p>
+ &ldquo;We must get him out, that's all,&rdquo; decided Mr. Jenks; with vigor. &ldquo;Get him
+ out and drop him overboard!&rdquo;
+ </p>
+ <p>
+ &ldquo;Drop him overboard!&rdquo; cried Mr. Parker, in horror.
+ </p>
+ <p>
+ &ldquo;Not exactly, but get rid of him,&rdquo; proceeded the diamond seeker. &ldquo;That man
+ is one of my enemies. He has been sent by the band of diamond makers
+ hidden among the mountains, to spy on me, and, if possible, prevent me
+ from seeking to discover their secret. He tried to work on Tom's Swift's
+ fears, and frighten him from using his airship on this quest. Then, when
+ he failed, the man must have sneaked into the shed, and hidden himself in
+ the ship. We must get rid of him, or he may wreck the Red Cloud!&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so!&rdquo; cried Tom. &ldquo;We must try to capture him. I think we had better&mdash;&rdquo;
+ the lad paused, and again listened to the wireless message. &ldquo;Father says
+ Eradicate saw the man have a gun, so we must be careful,&rdquo; the young
+ inventor translated the dots and dashes.
+ </p>
+ <p>
+ &ldquo;Bless my powder horn!&rdquo; exploded Mr. Damon.
+ </p>
+ <p>
+ &ldquo;We shall have to proceed cautiously then,&rdquo; spoke Mr. Jenks. &ldquo;If he is
+ like any others in the gang he is a desperate man.&rdquo;
+ </p>
+ <p>
+ &ldquo;Better sneak up on him then, if we can,&rdquo; proposed Mr. Parker. &ldquo;There are
+ enough of us to cope with one man, even if he is armed. You have weapons
+ aboard, haven't you?&rdquo; he inquired of Tom.
+ </p>
+ <p>
+ &ldquo;Yes,&rdquo; was the hesitating answer, &ldquo;but I don't want to use them if I can
+ help it. Not only because of the danger, and a dislike of shedding blood,
+ but because a stray bullet might pierce the gas bag and damage the ship.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so,&rdquo; agreed Mr. Jenks. &ldquo;Well, I guess if we go at it the right way
+ we can capture him without any shooting. But we must talk more quietly&mdash;we
+ ought to have whispered&mdash;he may have heard us.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't think so,&rdquo; replied Tom. &ldquo;The storeroom is far enough off so that
+ he couldn't hear us. Besides, the motor makes such a racket that he
+ couldn't distinguish what we were talking about, even if he heard our
+ voices. So, unless he heard the wireless working, and suspects something
+ from that, he probably doesn't know that we are aware of his presence
+ aboard.&rdquo;
+ </p>
+ <p>
+ &ldquo;But why do you think he has remained quiet all this while, Tom?&rdquo; asked
+ Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Probably he wants to wait until the ship is farther out west,&rdquo; suggested
+ Mr. Jenks. &ldquo;Then he will be nearer his friends, and can get help, if he
+ needs it.&rdquo;
+ </p>
+ <p>
+ &ldquo;And do you really believe he would destroy the Red Cloud?&rdquo; asked Mr.
+ Parker.
+ </p>
+ <p>
+ &ldquo;I think that all he is waiting for is a favorable chance,&rdquo; declared the
+ diamond seeker. &ldquo;He would destroy the craft, and us too, if he could
+ prevent us from discovering the secret of Phantom Mountain, I believe.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we must get ahead of him,&rdquo; decided Tom, quietly. &ldquo;I have just
+ flashed to dad a message, telling him that we will heed his warning. Now
+ to capture the stowaway!&rdquo;
+ </p>
+ <p>
+ &ldquo;And while we're about it, give him a good scare when we do get him,&rdquo;
+ suggested Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;How?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Threaten to drop him overboard. Perhaps that will make him tell how he
+ happened to get in our ship, and what are the plans of the gang of diamond
+ makers. We may get valuable information that way.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe you can scare such fellows much,&rdquo; was Tom's opinion, but
+ it was agreed to try.
+ </p>
+ <p>
+ &ldquo;How are you going to capture him?&rdquo; asked Mr. Parker. &ldquo;If he has a gun it
+ won't be any too easy to go in the storeroom, and drag him out.&rdquo;
+ </p>
+ <p>
+ &ldquo;We'll have to use a little strategy,&rdquo; decided Tom, and then they
+ discussed several plans. The one finally adopted was that Tom and Mr.
+ Damon should enter the storeroom, casually, as if in search of food to
+ cook for supper. They would discuss various dishes, and Mr. Damon was to
+ express a preference for something in the food line, the box containing
+ which, was well back in the room. This would give the two a chance to
+ penetrate to the far end of the apartment, without arousing the suspicions
+ of the hidden man, who, doubtless, would be listening to the conversation.
+ </p>
+ <p>
+ &ldquo;And as soon as we get sight of him, you and I will jump right at him, Mr.
+ Damon,&rdquo; said Tom. &ldquo;Jump before he has a chance to use his gun. Mr. Jenks
+ and Mr. Parker will be waiting outside the room, to catch him if he gets
+ away from us. I'll have some ropes ready, and we'll tie him up, and&mdash;well,
+ we'll decide later what to do with him.&rdquo;
+ </p>
+ <p>
+ &ldquo;All right. I'm ready as soon as you are, Tom,&rdquo; said the eccentric man.
+ &ldquo;Come ahead.&rdquo;
+ </p>
+ <p>
+ They went softly to the storeroom, and listened at the door. There was no
+ sound heard save that made by the machinery.
+ </p>
+ <p>
+ &ldquo;I wonder if he's really here?&rdquo; whispered Mr. Damon.
+ </p>
+ <p>
+ &ldquo;We'll soon find out,&rdquo; answered Tom. &ldquo;Let's go in.&rdquo;
+ </p>
+ <p>
+ They entered, and, in pursuance of their plan, Tom and his friend talked
+ of various foods.
+ </p>
+ <p>
+ &ldquo;I think I'd like some of that canned lobster, with French dressing on,&rdquo;
+ spoke the eccentric man.
+ </p>
+ <p>
+ &ldquo;That's away in the back end of the room,&rdquo; said Tom, in a loud voice.
+ &ldquo;It's under a lot of boxes.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then I'll help you get it out! Bless my frying pan! but I am very fond of
+ lobster!&rdquo; exclaimed Mr. Damon, in as natural tones as was possible under
+ the circumstances.
+ </p>
+ <p>
+ He and Tom moved cautiously back among the boxes and barrels. They were
+ glancing about with eager eyes. Tom switched on an electric light, and,
+ the instant he did so, he was aware of a movement in a little space formed
+ by one box which was placed on top, of two others. The lad saw a dark
+ figure moving, as if to get farther out of sight.
+ </p>
+ <p>
+ &ldquo;I've got him!&rdquo; cried Tom, making a dive for the shadow.
+ </p>
+ <p>
+ A moment later the young inventor was bowled over, as a dark figure leaped
+ over his head.
+ </p>
+ <p>
+ &ldquo;Catch him, Mr. Damon!&rdquo; he cried.
+ </p>
+ <p>
+ &ldquo;Bless my hatband! I&mdash;I&mdash;&rdquo; Mr. Damon's voice ended in a grunt.
+ He, too, had been knocked down by the fleeing man.
+ </p>
+ <p>
+ &ldquo;Look out, Mr. Jenks!&rdquo; cried Tom, to warn those on guard at the door of
+ the storeroom.
+ </p>
+ <p>
+ There was the report of a gun, some excited shouts, and when Tom could
+ scramble to his feet, and rush out, he beheld Mr. Parker calmly sitting on
+ a struggling man, while Mr. Jenks held a gun, that was still smoking.
+ </p>
+ <p>
+ &ldquo;We caught him!&rdquo; cried the scientist.
+ </p>
+ <p>
+ &ldquo;Anybody hurt?&rdquo; asked Tom, anxiously.
+ </p>
+ <p>
+ &ldquo;No, I knocked up his gun as he fired,&rdquo; explained Mr. Jenks. &ldquo;Where are
+ the ropes, Tom?&rdquo;
+ </p>
+ <p>
+ The cords were produced and the man, who had now ceased to struggle, was
+ tightly bound. He uttered not a word, but he smiled grimly when Mr. Damon
+ remarked:
+ </p>
+ <p>
+ &ldquo;I guess I'll go back in the storeroom, Tom, and see how much food he
+ ate.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I guess he didn't take much,&rdquo; declared the lad. &ldquo;He wasn't there long
+ enough.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, Farley Munson, so it's you, is it?&rdquo; asked Mr. Jenks, as he surveyed
+ the prisoner.
+ </p>
+ <p>
+ &ldquo;Do you know him?&rdquo; asked Tom, in some surprise.
+ </p>
+ <p>
+ &ldquo;He was in with the diamond makers,&rdquo; said Mr. Jenks. &ldquo;He was one of those
+ who took me to the secret cave. But it will be the last time he ever goes
+ there. How high up are we, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;About two miles. Why?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess that will be far enough to let him fall,&rdquo; went on the diamond
+ seeker. &ldquo;Come on, Mr. Damon, help me throw him overboard!&rdquo;
+ </p>
+ <p>
+ &ldquo;You&mdash;you're not going to throw me over&mdash;with the airship two
+ miles high; are you?&rdquo; gasped the man.
+ </p>
+ <p>
+ &ldquo;Will you tell us what we want to know, if we don't?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;What do you want to know?&rdquo;
+ </p>
+ <p>
+ &ldquo;How you got aboard, and what your object was in coming.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's easy enough. I had been hanging around the shed for several days,
+ watching a chance to get in. Finally I saw it, when that colored man went
+ to feed his mule, and I slipped in, and hid in the airship. The stores
+ were all in then, and I stowed myself away among the boxes. I had food and
+ water, so I didn't touch any of yours,&rdquo; and he looked at Mr. Damon, who
+ seemed much relieved.
+ </p>
+ <p>
+ &ldquo;And what was your object?&rdquo; demanded Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I wanted to prevent you from going to Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;How?&rdquo;
+ </p>
+ <p>
+ &ldquo;By destroying the airship if need be. But I hoped to accomplish it by
+ other means. I would have stopped at nothing, though, to prevent you. You
+ must keep away from there!&rdquo;
+ </p>
+ <p>
+ &ldquo;And if we refuse?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Then you'll have to take what comes!&rdquo;
+ </p>
+ <p>
+ &ldquo;But not from you!&rdquo; exclaimed Mr. Jenks. &ldquo;We're going to get rid of you.&rdquo;
+ </p>
+ <p>
+ The man's face showed the alarm he felt.
+ </p>
+ <p>
+ &ldquo;Oh, don't worry,&rdquo; said Mr. Jenks, quickly, &ldquo;we're not going to toss you
+ overboard. We're not as desperate as your crowd. But we're going to get
+ rid of you, and then go on before you can send any word to your
+ confederates. We'll put you off in the most lonesome spot we can find, and
+ I guess you'll be some time getting back to civilization. By that time
+ we'll have the secret of the diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;You never will!&rdquo; declared the man, firmly. And he would say nothing more,
+ though by threats and promises Mr. Jenks tried to get from him something
+ about the men in with him, and where the cave of the diamonds was located.
+ </p>
+ <p>
+ Heavily bound with ropes the man was locked in a small closet, to be kept
+ there until a favorable spot was reached for letting him go. Mr. Jenks'
+ plan, of dropping him down in some place where he would have difficulty in
+ sending on word to his confederates was considered a good one.
+ </p>
+ <p>
+ Three days later, in crossing over a lonely region, near the Nebraska
+ National Forest, Farley Munson, which was one of the names the spy went
+ by, was dropped off the airship, when it was sent down to within a few
+ feet of the earth.
+ </p>
+ <p>
+ &ldquo;It will take you some time to get to a telegraph office,&rdquo; said Mr. Jenks,
+ as a package of food, and a flask of water was tossed down to the
+ stowaway. He shook his fist at those in the airship, and shouted after
+ them:
+ </p>
+ <p>
+ &ldquo;You'll never discover the secret of Phantom Mountain!&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, we will,&rdquo; declared Tom, as he sent the Red Cloud high into the air
+ again.

+ <h2>
+ CHAPTER XI&mdash;A WEARY SEARCH
+ </h2>
+ <p>
+ During the three days when the stowaway had been kept a prisoner, the Red
+ Cloud had made good time on her western trip. She was now about two
+ hundred and fifty miles from Leadville, Colorado, and Tom knew he could
+ accomplish that distance in a short time. It was necessary, therefore,
+ since they were so close to the place where the real search would begin,
+ to make some more definite plans.
+ </p>
+ <p>
+ &ldquo;We will need to replenish our supply of gasoline,&rdquo; said Tom, shortly
+ after the stowaway had been dropped, and when the young inventor had made
+ a general inspection of the airship.
+ </p>
+ <p>
+ &ldquo;Is it all gone?&rdquo; inquired Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Not all, but we will soon be in the wildest part of the Rocky Mountains,
+ and gasoline is difficult to procure there. So I want to fill all our
+ reserve tanks. But I would rather do that before we get far into
+ Colorado.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo; inquired Mr. Parker.
+ </p>
+ <p>
+ &ldquo;Because airships are not so common but what the appearance of one
+ attracts attention. Ours is sure to be talked about, and commented on. In
+ that case, in spite of our precaution in putting Munson off in this lonely
+ place, word of the Red Cloud being in the vicinity of Leadville may reach
+ the diamond makers, and put them on their guard. We want to take them
+ unawares if we can.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so,&rdquo; agreed Mr. Jenks. &ldquo;We had better get our gasoline at the
+ first stopping place, then, and proceed with our search. Our first object
+ ought to be to look for the landmark&mdash;the head of stone. Then we can
+ begin to prospect about a bit.&rdquo;
+ </p>
+ <p>
+ &ldquo;My idea, exactly,&rdquo; declared Tom. &ldquo;Well, then, I'll go down at the first
+ place we cross, where we can get gasoline, and then we'll be in a position
+ to hover in the air for a long time, without descending.&rdquo;
+ </p>
+ <p>
+ The airship kept on her way, traveling slowly the remainder of that day,
+ and at dusk, when there was less chance of big crowds seeing them, the Red
+ Cloud was sent down on the outskirts of a large village. Tom and Mr. Damon
+ went to a supply store, and arranged to have a sufficient quantity of the
+ gasoline taken out to the airship. It was delivered after dark, and little
+ talk was occasioned by the few who were aware of the presence of the
+ craft. Then, once more, they went aloft, and Tom sent several wireless
+ messages to Shopton, including one to Miss Nestor.
+ </p>
+ <p>
+ &ldquo;Please tell my wife that I am well, and that I have a good appetite,&rdquo;
+ said Mr. Damon.
+ </p>
+ <p>
+ Mr. Parker also sent a message to a scientific friend of his, stating that
+ he made some observations among the mountains, of the region in which the
+ airship then was, and that the indications were that a great landslide
+ would soon take place.
+ </p>
+ <p>
+ &ldquo;That won't worry us,&rdquo; spoke Tom, &ldquo;for we'll be far above it.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope we will be near enough to enable me to observe it, and make some
+ scientific notes,&rdquo; came from Mr. Parker. &ldquo;I am positive that one of these
+ mountain peaks that we saw to-day will disappear in a landslide within a
+ few days. I have an instrument somewhat like the one that records
+ earthquakes, and it has been acting strangely of late.&rdquo;
+ </p>
+ <p>
+ Tom wondered what enjoyment Mr. Parker got out of life, when he was always
+ looking for some calamity to happen, but the scientist seemed to take as
+ much pleasure in his gloomy forebodings now, as he had on Earthquake
+ Island.
+ </p>
+ <p>
+ They reached the vicinity of Leadville the next day, but took care to keep
+ high above the city, so that the airship could not be observed. With
+ powerful glasses they examined the mountainous country, looking for the
+ little settlement of Indian Ridge.
+ </p>
+ <p>
+ &ldquo;There it is!&rdquo; exclaimed Mr. Jenks, just as dusk was settling down. &ldquo;I can
+ make out the hotel I stopped at. Now we can really begin our search. The
+ next thing is to find the stone head, and then, I think, I will have my
+ bearings.&rdquo;
+ </p>
+ <p>
+ &ldquo;We'll begin the hunt for that landmark in the morning,&rdquo; said Tom.
+ </p>
+ <p>
+ High in the air hovered the Red Cloud. At that distance above the earth
+ she must have looked like some great bird, and the adventurers thought it
+ unlikely that any one in the vicinity of Leadville would observe them.
+ </p>
+ <p>
+ The quest for the great mountain peak, that looked like a stone head, was
+ under way. Back and forth sailed the airship. Sometimes she was enveloped
+ in fog, and no sight could be had of the earth below. At other times there
+ were rain storms, which likewise prevented a view. Mr. Parker was on the
+ lookout for his predicted mountain landslide, but it did not occur, and he
+ was much disappointed.
+ </p>
+ <p>
+ &ldquo;It's queer I can't pick out that landmark,&rdquo; said Mr. Jenks after two days
+ of weary searching, when their eyes were strained from long peering
+ through telescopes. &ldquo;I'm sure it was around Indian Ridge, yet we've
+ covered almost all the ground in this neighborhood, and I haven't had a
+ glimpse of it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps it was destroyed in a landslide, or some cataclysm of nature,&rdquo;
+ suggested Mr. Parker. &ldquo;That is very possible.&rdquo;
+ </p>
+ <p>
+ &ldquo;If that's the case we're going to have a hard time to locate the cave of
+ the diamond makers,&rdquo; answered Mr. Jenks, &ldquo;but I hope it isn't so.&rdquo;
+ </p>
+ <p>
+ They continued the search for another day, and then Tom, as they sat in
+ the comfortable cabin of the airship that night, hovering almost
+ motionless (for the motor had been shut down) made a proposition.
+ </p>
+ <p>
+ &ldquo;Why not descend in some secluded place,&rdquo; he suggested, &ldquo;and wander around
+ on foot, making inquiries of the miners. They may know where the stone
+ head is, or they may even know about Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;Good idea,&rdquo; spoke Mr. Jenks. &ldquo;We'll do it.&rdquo;
+ </p>
+ <p>
+ Accordingly, the next morning, the Red Cloud was lowered in a good but
+ lonely landing place, and securely moored. It was in a valley, well
+ screened from observation, and the craft was not likely to be seen, but,
+ to guard against any damage being done to it by passing hunters or miners,
+ Mr. Parker and Mr. Damon agreed to remain on guard in it, while Tom and
+ Mr. Jenks spent a day or two traveling around, making inquiries.
+ </p>
+ <p>
+ The young inventor and his companion proceeded on foot to a small
+ settlement, where they hired horses on which to make their way about. They
+ were to be gone two days, and in that time they hoped to get on the right
+ trail.

+ <h2>
+ CHAPTER XII&mdash;THE GREAT STONE HEAD
+ </h2>
+ <p>
+ It was a wild and desolate country in which Tom Swift and Mr. Jenks were
+ traveling. Villages were far apart, and they were at best but small
+ settlements. In their journeys from place to place they met few travelers.
+ </p>
+ <p>
+ But of these few they made cautious inquiries as to the location of
+ Phantom Mountain, or the landmark known as the great stone head.
+ Prospectors, miners and hunters, whom they asked, shook their heads.
+ </p>
+ <p>
+ &ldquo;I've heard of Phantom Mountain,&rdquo; said one grizzled miner, &ldquo;but I couldn't
+ say where it is. Maybe it's only a fish story&mdash;the place may not even
+ exist.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, it does, for I've been there!&rdquo; exclaimed Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Then why don't you go back to it?&rdquo; asked the miner.
+ </p>
+ <p>
+ &ldquo;Because I can't locate it again,&rdquo; was the reply.
+ </p>
+ <p>
+ &ldquo;Humph! Mighty queer if you've seen a place once, and can't get to it
+ again,&rdquo; and the man looked as if he thought there was something strange
+ about Tom and his companion. Mr. Jenks did not want to say that he had
+ been taken to the mountain blindfolded, for that would have caused too
+ much talk.
+ </p>
+ <p>
+ &ldquo;I think if we spent to-night in a place where the miners congregate,
+ listened to their talk, and put a few casual questions to them, more as if
+ we were only asking out of idle curiosity, we might learn something,&rdquo;
+ suggested Tom.
+ </p>
+ <p>
+ &ldquo;Very well, we'll try that scheme.&rdquo;
+ </p>
+ <p>
+ Accordingly, after they had left the suspicious miner the two proceeded to
+ a small milling town, not far from Indian Ridge. There they engaged rooms
+ for the night at the only hotel, and, after supper they sat around the
+ combined dance hall and gambling place.
+ </p>
+ <p>
+ There were wild, rough scenes, which were distasteful to Tom, and to Mr.
+ Jenks, but they felt that this was their only chance to get on the right
+ trail, and so they stayed. As strangers in a western mining settlement
+ they were made roughly welcome, and in response to their inquiries about
+ the country, they were told many tales, some of which were evidently
+ gotten up for the benefit of the &ldquo;tenderfeet.&rdquo;
+ </p>
+ <p>
+ &ldquo;Is there a place around here called Phantom Mountain?&rdquo; asked Tom, at
+ length, as quietly as he could.
+ </p>
+ <p>
+ &ldquo;Never heard of it, stranger,&rdquo; replied a miner who had done most of the
+ talking. &ldquo;I never heard of it, and what Bill Slatterly don't know ain't
+ worth knowin'. I'm Bill Slatterly,&rdquo; he added, lest there be some doubt on
+ that score.
+ </p>
+ <p>
+ &ldquo;Isn't there some sort of a landmark around here shaped like a great stone
+ head?&rdquo; went on Tom, after some unimportant questions. &ldquo;Seems to me I've
+ heard of that.&rdquo;
+ </p>
+ <p>
+ &ldquo;Nary a one,&rdquo; answered Mr. Slatterly. &ldquo;No stone heads, and no Phantom
+ Mountains&mdash;nary a one.
+ </p>
+ <p>
+ &ldquo;Who says there ain't no Phantom Mountains?&rdquo; demanded an elderly miner,
+ who had been dozing in one corner of the room, but who was awakened by
+ Slatterly's loud voice. &ldquo;Who says so?&rdquo;
+ </p>
+ <p>
+ &ldquo;I do,&rdquo; answered the one who claimed to know everything.
+ </p>
+ <p>
+ &ldquo;Then you're wrong!&rdquo; Tom's heart commenced beating faster than usual.
+ </p>
+ <p>
+ &ldquo;Do you mean to say you've seen Phantom Mountain, Jed Nugg?&rdquo; demanded
+ Slatterly.
+ </p>
+ <p>
+ &ldquo;No, I ain't exactly seen it, an' I don't want to, but there is such a
+ place, about sixty mile from here. Folks says it's haunted, and them sort
+ of places I steer clear from.&rdquo;
+ </p>
+ <p>
+ &ldquo;Can you tell me about it?&rdquo; asked Mr. Jenks, eagerly. &ldquo;I am interested in
+ such things.&rdquo;
+ </p>
+ <p>
+ &ldquo;I can't tell you much about it,&rdquo; was the reply, &ldquo;and I wouldn't git too
+ interested, if I was you. It might not be healthy. All I know is that one
+ time my partner and I were in hard luck. We got grub-staked, and went out
+ prospectin'. We strayed into a wild part of the country about sixty mile
+ from here, and one night we camped on a mountain&mdash;a wild, desolate
+ place it was too.&rdquo;
+ </p>
+ <p>
+ The miner stopped, and began leisurely filling his pipe.
+ </p>
+ <p>
+ &ldquo;Well?&rdquo; asked Tom, trying not to let his voice sound too eager.
+ </p>
+ <p>
+ &ldquo;Well, that was Phantom Mountain.&rdquo;
+ </p>
+ <p>
+ The miner seemed to have finished his story.
+ </p>
+ <p>
+ &ldquo;Is that all?&rdquo; asked Mr. Jenks. &ldquo;How did you know it was Phantom
+ Mountain?&rdquo;
+ </p>
+ <p>
+ &ldquo;'Cause we seen the ghost&mdash;my partner and I&mdash;that's why!&rdquo;
+ exclaimed the man, puffing on his pipe. &ldquo;As I said, we was campin' there,
+ and 'long about midnight we seen somethin' tall and white, and all
+ shimmerin', with a sort of yellow fire, slidin' down the side of the
+ mountain. It made straight for our camp.&rdquo;
+ </p>
+ <p>
+ &ldquo;Huh! Guess you run, didn't you, Jed?&rdquo; asked Bill Slatterly.
+ </p>
+ <p>
+ &ldquo;Course we did. You'd a run too, if you seen a ghost comm' at you, an'
+ firin' a gun.&rdquo;
+ </p>
+ <p>
+ &ldquo;Ghosts can't fire guns!&rdquo; declared Bill. &ldquo;I guess you dreamed it, Jed.&rdquo;
+ </p>
+ <p>
+ &ldquo;Ghosts can't fire guns, eh? That's all you know about it. This one did,
+ and to prove I didn't dream it, there was a bullet hole in my hat next
+ mornin'. I could prove it, too, only I ain't got that hat any more. But
+ that was Phantom Mountain, strangers, an' my advice to you is to keep away
+ from it. I was on it but I didn't exactly see it, 'cause it was dark at
+ the time.&rdquo;
+ </p>
+ <p>
+ &ldquo;Was it near a peak that looked like a stone head?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;It were, stranger, but I didn't take much notice of it. Me and my partner
+ got out of them diggin's next day, and I never went back. I ain't never
+ said much about this place, but it's called Phantom Mountain all right,
+ and I ain't the only one that's seen a ghost there. Other grub-stakers has
+ had the same experience.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why ain't I never heard about it?&rdquo; demanded Bill, suspiciously.
+ </p>
+ <p>
+ &ldquo;'Cause as why you're allers so busy talkin' that you don't never listen
+ to nothin' I reckon,&rdquo; was Jed's answer, amid laughter.
+ </p>
+ <p>
+ &ldquo;Can you tell us what trail to take to get there?&rdquo; asked Tom, of the
+ miner.
+ </p>
+ <p>
+ &ldquo;Yes, it's called the old silver trail, and you strike it by goin' to a
+ place called Black Gulch, about forty mile from here. Then it's twenty
+ mile farther on. But take my advice and don't go.&rdquo;
+ </p>
+ <p>
+ &ldquo;Can it be reached by way of Indian Ridge?&rdquo; asked Mr. Jenks, wondering how
+ he had been taken to the cave of the diamond makers. He did not remember
+ Black Gulch.
+ </p>
+ <p>
+ &ldquo;Yes, you can git there by Indian Ridge way, but it's more dangerous.
+ You're likely to lose your way, for that's a trail that's seldom
+ traveled.&rdquo; Mr. Jenks thought that, perhaps, was the reason the gang had
+ taken him that way. &ldquo;It's easier to get to the stone head and Phantom
+ Mountain by Black Gulch, but it ain't healthy to go there, strangers, take
+ my advice on that,&rdquo; concluded the miner, as he prepared to go to sleep
+ again.
+ </p>
+ <p>
+ Tom could scarcely contain the exultation he felt. At last, it seemed,
+ they were on the trail. He motioned to Mr. Jenks, and they slipped quietly
+ from the place, just as another dance was beginning.
+ </p>
+ <p>
+ &ldquo;Now for Black Gulch!&rdquo; cried Tom. &ldquo;We must hurry back to the airship, and
+ tell the good news.
+ </p>
+ <p>
+ &ldquo;It's too late to-night,&rdquo; decided Mr. Jenks, and so they waited until
+ morning, when they made an early start.
+ </p>
+ <p>
+ They found Mr. Damon and Mr. Parker anxiously awaiting their return. Mr.
+ Damon blessed so many things that he was nearly out of breath, and Mr.
+ Parker related something of the observations he had made.
+ </p>
+ <p>
+ &ldquo;I think I have discovered traces of a dormant volcano,&rdquo; he said. &ldquo;I am in
+ hopes that it will have an eruption while we are here.&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm not,&rdquo; spoke Tom, decidedly. &ldquo;We'll start for Black Gulch as soon as
+ possible.&rdquo;
+ </p>
+ <p>
+ The airship once more rose in the air, and, following the directions the
+ miner had given him, Tom pointed his craft for the depression in the
+ mountains which had been given the name Black Gulch. It was reached in a
+ short time, and then, making a turn up a long valley the airship proceeded
+ at reduced speed.
+ </p>
+ <p>
+ &ldquo;We ought to see that stone head soon now,&rdquo; spoke Tom, as he peered from
+ the windows of the pilot house.
+ </p>
+ <p>
+ &ldquo;It's queer we didn't notice it when we were up in the air,&rdquo; remarked Mr.
+ Jenks. &ldquo;We've been over this place before, I'm sure of it.&rdquo;
+ </p>
+ <p>
+ The next moment Mr. Damon uttered a cry. &ldquo;Bless my watch-chain!&rdquo; he
+ exclaimed. &ldquo;Look at that!&rdquo;
+ </p>
+ <p>
+ He pointed off to the left. There, jutting out from the side of a steep
+ mountain peak was a mass of stone&mdash;black stone&mdash;which, as the
+ airship slowly approached, took the form and shape of a giant's head.
+ </p>
+ <p>
+ &ldquo;That's it! That's it!&rdquo; cried Tom. &ldquo;The great stone head!&rdquo;
+ </p>
+ <p>
+ &ldquo;And now for Phantom Mountain and the diamonds!&rdquo; shouted Mr. Jenks, as Tom
+ let the airship slowly settle to the bottom of the valley.

+ <h2>
+ CHAPTER XIII&mdash;ON PHANTOM MOUNTAIN
+ </h2>
+ <p>
+ Out from the Red Cloud piled Tom and the others. They made a rush for the
+ irregular mass of rock which bore so strong a resemblance to the head of
+ some gigantic man.
+ </p>
+ <p>
+ &ldquo;That's the one! That's the thing I saw when they were taking me along
+ here blindfolded!&rdquo; exclaimed Mr. Jenks. &ldquo;I'm sure we're on the right
+ trail, now!&rdquo;
+ </p>
+ <p>
+ &ldquo;But what gets me, though,&rdquo; remarked Mr. Damon, &ldquo;is why we couldn't see
+ that landmark when we were up in the air. We had a fine view, and ought to
+ have been able to pick it out with the telescopes.&rdquo;
+ </p>
+ <p>
+ The adventurers saw the reason a few seconds later. The image was visible
+ only from one place, and that was directly looking up the valley. If one
+ went too far to the right or left the head disappeared from view behind
+ jutting crags, and it was impossible to see it from overhead, because the
+ head was almost under a great spur of a mighty mountain.
+ </p>
+ <p>
+ &ldquo;We might have hunted for it a week in the airship, and been directly over
+ it,&rdquo; said Tom, &ldquo;and yet we would never have seen it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, but we never would have gotten here in such good shape if it hadn't
+ been for your wonderful craft,&rdquo; declared Mr. Jenks. &ldquo;It brought us here
+ safely and quickly, and enabled us to elude the men who tried to keep us
+ back. We're here in spite of them. If we had traveled by train they might
+ have interfered with us in a dozen ways.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's so,&rdquo; agreed Mr. Damon. &ldquo;Well, now we're here, what's to be done?
+ Which way do we start to reach the cave where the diamonds are
+ manufactured, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;That I can't say. As you know, I only had a momentary glimpse of this
+ stone head as they were taking me along the trail. Then one of the men
+ noticed that the bandage had slipped and he pulled it into place. So I
+ really can't say which direction to take now, in order to discover the
+ secret.&rdquo;
+ </p>
+ <p>
+ &ldquo;How long after you saw the head before you reached the cave?&rdquo; asked Tom.
+ &ldquo;In that way we may be able to tell how far away it is.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I should say it was about two or three hours after I saw the head,
+ before we got to the halting place, and I was carried into the cave. That
+ would make it several miles from here, for we went in a wagon.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, and they might have driven in a round-about way, in order to deceive
+ you,&rdquo; suggested Mr. Damon. &ldquo;At best we have but a faint idea where the
+ diamond cave is, but we must search for it; eh, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Certainly. We'll start right in. And as the airship will be of but little
+ service to us now, I suggest that we leave it in this valley. It is very
+ much secluded, and no one will harm it, I think. We can then start off
+ prospecting, for I have a large portable tent, and we can carry enough
+ food with us, with what game we can shoot, to enable us to live. I have a
+ regular camping outfit on board.&rdquo;
+ </p>
+ <p>
+ &ldquo;Fine!&rdquo; cried Mr. Parker, &ldquo;and that will give me a chance to make some
+ observations among the mountains, and perhaps I can predict when a
+ landslide, or an eruption of some dormant volcano, may occur.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my stars!&rdquo; cried Mr. Damon. &ldquo;I don't wish you any bad luck, Mr.
+ Parker, but I sincerely hope nothing of the sort happens! We had enough of
+ that on Earthquake Island!&rdquo;
+ </p>
+ <p>
+ &ldquo;One can not halt the forces of nature,&rdquo; said the scientist, solemnly.
+ &ldquo;There are many towering peaks around here which may contain old
+ volcanoes. And I notice the presence of iron ore all about. This must be a
+ wonderful place in a thunder and lightning storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo; asked Tom, curiously.
+ </p>
+ <p>
+ &ldquo;Because lightning would be powerfully attracted here by the presence of
+ the metal. In fact there is evidence that many of the peaks have been
+ struck by lightning,&rdquo; and the scientist showed curious, livid scars on the
+ stone faces of the peaks within sight.
+ </p>
+ <p>
+ &ldquo;Then this is a good place to stay away from in a storm,&rdquo; observed Mr.
+ Damon. &ldquo;However, we won't worry about that now. If this is the landmark
+ Mr. Jenks was searching for, then we must be in the vicinity of Phantom
+ Mountain.&rdquo;
+ </p>
+ <p>
+ &ldquo;I think we are,&rdquo; declared the diamond seeker. &ldquo;Probably it is within
+ sight now, but there are so many peaks, and this is such a wild and
+ desolate part of the country that we may have trouble in locating it.&rdquo;
+ </p>
+ <p>
+ &ldquo;We've got to make a beginning, anyhow,&rdquo; decided Tom, &ldquo;and the sooner the
+ better. Come, we'll make up our camping kits, and start out.&rdquo;
+ </p>
+ <p>
+ It was something to know that they were on the right trail, and it was a
+ relief to be able to busy oneself, and not be aimlessly searching for a
+ mysterious landmark. They all felt this, and soon the airship was taken to
+ a secluded part of the valley, where it was well hidden from sight in a
+ grove of trees.
+ </p>
+ <p>
+ Tom and Mr. Damon then served a good meal, and preparations were made to
+ start on their search among the mountains&mdash;a search which they hoped
+ would lead them to Phantom Mountain, and the cave of the diamond makers.
+ </p>
+ <p>
+ The tent which would afford them shelter was in sections, and could be
+ laced together. They carried food, compressed into small packages, coffee,
+ a few cooking utensils; and each one had a gun, Tom carrying a combination
+ rifle and shotgun, for game.
+ </p>
+ <p>
+ &ldquo;We can't live very high while we're on the trail,&rdquo; said the young
+ inventor, &ldquo;but it won't be much worse than it was on Earthquake Island.
+ Are we all ready?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess so,&rdquo; answered Mr. Damon. &ldquo;How long are we going to be away?&rdquo;
+ </p>
+ <p>
+ &ldquo;Until we find the diamond makers!&rdquo; declared Tom, firmly.
+ </p>
+ <p>
+ Shouldering their packs, the adventurers started off. Tom turned for a
+ last look at his airship, dimly seen amid the trees. Would he ever come
+ back to the Red Cloud? Would she be there when he did return? Would their
+ quest be successful? These questions the lad asked himself, as he followed
+ his companions along the rocky trail.
+ </p>
+ <p>
+ &ldquo;Perhaps we can find the road by which these men go in and out of the
+ cave,&rdquo; suggested Mr. Damon, when they had gone on for several miles.
+ </p>
+ <p>
+ &ldquo;I fancy not,&rdquo; replied Mr. Jenks. &ldquo;They probably take great pains to hide
+ it. I think though, that our best plan will be to go here and there,
+ looking for the entrance to the cave. I believe I would remember the
+ place.&rdquo;
+ </p>
+ <p>
+ &ldquo;But why can't you follow the directions given by the miner who told you
+ about Phantom Mountain?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Because his talk was too indefinite,&rdquo; answered Mr. Jenks. &ldquo;He was so
+ frightened by seeing what he believed to be a ghost, that he didn't take
+ much notice of the location of the place. All he knows is that Phantom
+ Mountain is somewhere around here.&rdquo;
+ </p>
+ <p>
+ &ldquo;And we've got to hunt until we find it; is that the idea?&rdquo; asked Mr.
+ Parker.
+ </p>
+ <p>
+ &ldquo;Or until we see the phantom,&rdquo; added Tom, in a low voice.
+ </p>
+ <p>
+ &ldquo;Bless my topknot!&rdquo; exclaimed Mr. Damon. &ldquo;You don't mean to say you expect
+ to see that ghost; do you Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps,&rdquo; answered the young inventor, and he did not add something else
+ of which he was thinking. For Tom had a curious theory regarding the
+ phantom.
+ </p>
+ <p>
+ They tramped about the remainder of that day. Toward evening Tom shot some
+ birds, which made a welcome addition to their supper. Then the tent was
+ put together, some spruce and hemlock boughs were cut to make a soft bed,
+ and on these, while the light of a campfire gleamed in on them, the
+ adventurers slept.
+ </p>
+ <p>
+ Their experience the following day was similar to the first. They saw no
+ evidence of a large cave such as Mr. Jenks had described, nor were there
+ any traces of men having gone back and forth among the mountains, as might
+ have been expected of the diamond makers, for, as Mr. Jenks had said, they
+ made frequent journeys to the settlement for food, and other supplies.
+ </p>
+ <p>
+ &ldquo;Well, I haven't begun to give up yet,&rdquo; announced Tom, on the third day,
+ when their quest was still unsuccessful. &ldquo;But I think we are making one
+ mistake.&rdquo;
+ </p>
+ <p>
+ &ldquo;What is that?&rdquo; inquired Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I think we should go up higher. In my opinion the cave is near the top of
+ some peak; isn't it, Mr. Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I have that impression, though, as you know, I never saw the outside of
+ it. Still, it might not be a bad idea to ascend some of these peaks.&rdquo;
+ </p>
+ <p>
+ Following this suggestion, they laid their trail more toward the sky, and
+ that night found them encamped several thousand feet above the sea-level.
+ It was quite cool, and the campfire was a big one about which they sat
+ after supper, talking of many things.
+ </p>
+ <p>
+ Tom did not sleep well that night. He tossed from side to side on the bed
+ of boughs, and once or twice got up to replenish the fire, which had
+ burned low. His companions were in deep slumber.
+ </p>
+ <p>
+ &ldquo;I wonder what time it is?&rdquo; mused Tom, when he had been up the third time
+ to throw wood on the blaze. &ldquo;Must be near morning.&rdquo; He looked at his
+ watch, and was somewhat startled to see that it was only a little after
+ twelve. Somehow it seemed much later.
+ </p>
+ <p>
+ As he was putting the timepiece back into his pocket the lad looked around
+ at the dark and gloomy mountains, amid which they were encamped. As his
+ gaze wandered toward the peak of the one on the side of which the tent was
+ pitched, he gave a start of surprise.
+ </p>
+ <p>
+ For, coming down a place where, that afternoon, Tom had noticed a sort of
+ indefinite trail was a figure in white. A tall, waving figure, which
+ swayed this way and that&mdash;a figure which halted and then came on
+ again.
+ </p>
+ <p>
+ &ldquo;I wonder&mdash;I wonder if that can be a wisp of fog?&rdquo; mused the young
+ inventor. He rubbed his eyes, thinking it might be a swirling of the night
+ mist or a defect of vision. Then, as he saw more plainly, he noticed the
+ thing in white rushing toward him.
+ </p>
+ <p>
+ &ldquo;It's the phantom&mdash;the phantom!&rdquo; cried Tom, aloud. &ldquo;It's the thing
+ the miner saw! We're on Phantom Mountain now!&rdquo;

+ <h2>
+ CHAPTER XIV&mdash;WARNED BACK
+ </h2>
+ <p>
+ Tom's cries awakened the sleepers in the tent. Mr. Damon was the first to
+ rush out.
+ </p>
+ <p>
+ &ldquo;Bless my nightcap, Tom!&rdquo; he cried. &ldquo;What is it? What has happened? Are we
+ attacked by a mountain lion?&rdquo;
+ </p>
+ <p>
+ For answer the young inventor pointed up the mountain, to where, in the
+ dim light from a crescent moon, there stood boldly revealed, the figure in
+ white.
+ </p>
+ <p>
+ &ldquo;Bless&mdash;bless my very existence!&rdquo; cried the odd man. &ldquo;What is it,
+ Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;The phantom,&rdquo; was the quiet answer. &ldquo;Watch it, and see what it does.&rdquo;
+ </p>
+ <p>
+ By this time Mr. Jenks and Mr. Parker had joined Tom and Mr. Damon. The
+ four diamond seekers stood gazing at the apparition. And, as they looked,
+ the thing in white, seemingly too tall for any human being, slid slowly
+ forward, with a gliding motion. Then it raised its long, white arms, and
+ waved them threateningly at the adventurers.
+ </p>
+ <p>
+ &ldquo;It's motioning us to go back,&rdquo; said Mr. Parker in an awed whisper. &ldquo;It
+ doesn't want us to go any farther.&rdquo;
+ </p>
+ <p>
+ &ldquo;Very likely,&rdquo; agreed Tom, coolly. &ldquo;But we're not going to be frightened
+ by anything like that; are we?&rdquo;
+ </p>
+ <p>
+ &ldquo;Not much!&rdquo; exclaimed Mr. Jenks. &ldquo;I expected this. A ghost can't drive me
+ back from getting my rights from those scoundrels!&rdquo;
+ </p>
+ <p>
+ &ldquo;Suppose it uses a revolver to back up its demand?&rdquo; asked the scientist.
+ </p>
+ <p>
+ &ldquo;Wait until it does,&rdquo; answered Mr. Jenks. But the figure in white
+ evidently had no such intentions. It came on a little distance farther,
+ still waving the long arms threateningly, and then it suddenly
+ disappeared, seeming to dissolve in the misty shadows of the night.
+ </p>
+ <p>
+ &ldquo;Bless my suspenders!&rdquo; cried Mr. Damon. &ldquo;That's a very strange proceeding!
+ Very strange! What do you make of it, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;It is evidently some man dressed up in a sheet,&rdquo; declared Mr. Jenks. &ldquo;I
+ expected as much.&rdquo;
+ </p>
+ <p>
+ &ldquo;The work of those diamond makers; do you think?&rdquo; continued Mr. Damon.
+ </p>
+ <p>
+ &ldquo;I believe so,&rdquo; answered Tom, slowly, for he was trying to think it out.
+ &ldquo;I believe they are the cause of the phantom, though I don't know that
+ it's a man dressed in a sheet.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why isn't it?&rdquo; demanded Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Because it was too tall for a man, unless he's a giant.&rdquo;
+ </p>
+ <p>
+ &ldquo;He may have been on stilts,&rdquo; suggested Mr. Parker.
+ </p>
+ <p>
+ &ldquo;No man on stilts could walk along that way,&rdquo; declared Tom, confidently.
+ &ldquo;He glided along too easily. I am inclined to think it may be some sort of
+ a light.&rdquo;
+ </p>
+ <p>
+ &ldquo;A light?&rdquo; queried Mr. Damon.
+ </p>
+ <p>
+ &ldquo;Yes, the diamond makers may be hidden in some small cave near here, and
+ they may have some sort of a magic lantern or a similar arrangement, for
+ throwing a shadow picture. They could arrange it to move as they liked,
+ and could cause it to disappear at will. That, I think, is the ghost we
+ have just seen.&rdquo;
+ </p>
+ <p>
+ &ldquo;But the diamond makers have only been in this mountain recently,&rdquo;
+ objected Mr. Jenks, &ldquo;and the phantom was here before them. In fact, that
+ was what gave the place its name.&rdquo;
+ </p>
+ <p>
+ &ldquo;That may be,&rdquo; admitted the lad. &ldquo;There are many places that have the name
+ of being haunted, but no one ever sees the ghost. It is always some one
+ else, who has heard of some one who has seen it. That may have been the
+ case here. I grant that this place may have been called 'Phantom Mountain'
+ for a number of years, due to the superstitious tales of miners. The
+ diamond makers came along, found the conditions just right for their work,
+ and adopted the ghost, so to speak. As there wasn't any real spirit they
+ made one, and they use it to scare people away. I think that's what we've
+ just seen, though I may be wrong in my theory as to what the phantom is.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it's gone now, at any rate,&rdquo; said Mr. Jenks, &ldquo;and I think we'd
+ better get back inside the tent. It's cold out here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Aren't some of us going to stand guard?&rdquo; demanded Mr. Damon.
+ </p>
+ <p>
+ &ldquo;What for?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Why&mdash;er&mdash;bless my key-ring! Suppose that ghost takes a notion
+ to come down here, and use his gun, as he did on the miners?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe that will happen,&rdquo; remarked Tom. &ldquo;The diamond makers, if
+ the white thing had anything to do with them, have given us a warning, and
+ I think they'll at least wait until morning to see how we heed it.&rdquo;
+ </p>
+ <p>
+ &ldquo;We aren't going to heed it!&rdquo; burst out Mr. Jenks. &ldquo;I'm going to go right
+ ahead and find that cave where they make diamonds!&rdquo;
+ </p>
+ <p>
+ &ldquo;And we're with you!&rdquo; exclaimed Tom. &ldquo;We'll have a good fire going the
+ rest of the night, and that may keep intruders away. In the morning we'll
+ begin our search, and we'll go up the trail where we saw the white
+ figure.&rdquo;
+ </p>
+ <p>
+ A big pile of wood had been collected for the fire, and Tom now piled some
+ logs and branches on the blaze. It would last for some time now, and the
+ adventurers, still talking of the &ldquo;ghost&rdquo; went back into the tent. It was
+ over an hour before they all got to sleep again, and Mr. Jenks and Mr.
+ Damon took turns in getting up once or twice during the remainder of the
+ night to replenish the fire.
+ </p>
+ <p>
+ Morning dawned without anything further having occurred to disturb them,
+ and, after a hearty breakfast, to which Tom added some fish he caught in a
+ nearby mountain stream, they set off up the trail on Phantom Mountain.
+ </p>
+ <p>
+ They had left their tent standing, as they proposed making that spot their
+ headquarters until they located the cave they were seeking. What their
+ course would be after that would depend on the circumstances.
+ </p>
+ <p>
+ If they had expected to have an easy task locating the cavern in which Mr.
+ Jenks had seen diamonds made, the adventurers were disappointed. All that
+ day they tramped up and down the mountain, looking for some secret
+ entrance, but none was disclosed. The higher they went up the great peak,
+ the fainter became the trail, until, at length it vanished completely.
+ </p>
+ <p>
+ But this was not to be wondered at, since it was on solid rock, in which
+ no footsteps would leave an impression.
+ </p>
+ <p>
+ &ldquo;They never brought you up here in a wagon, Mr. Jenks,&rdquo; decided Tom, when
+ he saw how steep the place was.
+ </p>
+ <p>
+ &ldquo;I'm inclined to think so myself,&rdquo; admitted the diamond man. &ldquo;They must
+ have reached the cave from some other way. As a matter of fact, I walked
+ some distance after getting out of the vehicle, before we got to the
+ cavern. But, even at that, I don't believe we came this way.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yet the phantom was here,&rdquo; persisted Tom, &ldquo;and I'm convinced that the
+ cave is in this neighborhood. It's up to us to find it!&rdquo;
+ </p>
+ <p>
+ But they searched the remainder of that day in vain, and as night was
+ coming on, they made their way back to the camp. As Tom, who was in the
+ lead, approached the tent, he saw something black fastened to the
+ entrance.
+ </p>
+ <p>
+ &ldquo;Hello!&rdquo; he cried. &ldquo;Some one's been here. That wasn't on the tent when we
+ left this morning.&rdquo;
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;A black piece of paper, written on with white ink,&rdquo; replied the lad. He
+ was reading it, and, as he perused it a look of surprise came over his
+ face.
+ </p>
+ <p>
+ &ldquo;Listen to this!&rdquo; called Tom. &ldquo;It's evidently from the diamond makers.&rdquo;
+ </p>
+ <p>
+ Holding up the black paper, on which the white writing stood out in bold
+ relief Tom read aloud:
+ </p>
+ <p>
+ &ldquo;Be warned in time! Go back before it is too late! You are near to death!
+ Go back!&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my shoelaces!&rdquo; cried Mr. Damon. &ldquo;This is getting serious.&rdquo;
+ </p>

+ <h2>
+ CHAPTER XV&mdash;THE LANDSLIDE
+ </h2>
+ <p>
+ Gathered about the young inventor, the three men looked at the warning.
+ The writing was poor, and it was evident that an attempt had been made to
+ disguise it. But there was no misspelling of words, and there were no
+ rudely drawn daggers, or bloody hands or anything of that sort. In fact,
+ it was a very business-like sort of warning.
+ </p>
+ <p>
+ &ldquo;Rather odd,&rdquo; commented Mr. Jenks. &ldquo;Black paper and white ink.&rdquo;
+ </p>
+ <p>
+ &ldquo;White ink is easy enough to make,&rdquo; stated Mr. Parker. &ldquo;I fancy they
+ wanted it as conspicuous as possible.&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes,&rdquo; agreed Tom, &ldquo;and this warning, together with the antics of the
+ thing in white last night, shows that they are aware of our presence here,
+ and perhaps know who we are. We will have to be on our guard.&rdquo;
+ </p>
+ <p>
+ &ldquo;Do you think that fellow Munson, whom we left in the forest, could have
+ gotten here and warned them?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;It's possible,&rdquo; admitted Tom, &ldquo;but now let's see if the person who pinned
+ this warning on our tent took any of our things.&rdquo;
+ </p>
+ <p>
+ A hasty examination, however, showed that nothing had been disturbed, and
+ Tom and Mr. Damon were soon getting supper ready, everyone talking, during
+ the progress of the meal, about the events of the day, and the rather
+ weird culmination of it.
+ </p>
+ <p>
+ &ldquo;Well, we haven't had a great deal of success&mdash;so far,&rdquo; admitted Tom,
+ as they sat about the fire, in the fast gathering dusk. &ldquo;I think, perhaps,
+ we'd better try on the other side of the mountain to-morrow. We've
+ explored this side pretty thoroughly.&rdquo;
+ </p>
+ <p>
+ &ldquo;Good idea,&rdquo; commented Mr. Jenks. &ldquo;We'll do it, and move our camp. I only
+ hope those fellows don't find our airship and destroy it. We'll have a
+ hard time getting back to civilization again, if we have to walk all the
+ way.&rdquo;
+ </p>
+ <p>
+ This contingency caused Tom some uneasiness. He did not like to think that
+ the unscrupulous men might damage the Red Cloud, that had been built only
+ after hard labor. But he knew he could accomplish nothing by worrying, and
+ he tried to dismiss the matter from his mind.
+ </p>
+ <p>
+ They rather expected to see the thing in white again that night, but it
+ did not appear, and morning came without anything having disturbed their
+ heavy sleep, for they were tired from the day's tramp.
+ </p>
+ <p>
+ It took them the greater part of the day to make a circuit of the base of
+ Phantom Mountain in order to get to a place where a sort of trail led
+ upward.
+ </p>
+ <p>
+ &ldquo;It's too late to do anything to-night,&rdquo; decided Tom, as they set up the
+ tent. &ldquo;We'll rest, and start the first thing in the morning.&rdquo;
+ </p>
+ <p>
+ &ldquo;And the ghost isn't likely to find us here,&rdquo; added Mr. Damon. &ldquo;Where are
+ you going, Mr. Parker?&rdquo; he asked, as he saw the scientist tramping a
+ little way up the side of the mountain.
+ </p>
+ <p>
+ &ldquo;I am going to make some observations,&rdquo; was the answer, and no one paid
+ any more attention to him for some time. Supper was nearly ready when Mr.
+ Parker returned. His face wore a rather serious air, and Mr. Damon, noting
+ it, asked laughingly:
+ </p>
+ <p>
+ &ldquo;Well, did you discover any volcanoes, that may erupt during the night,
+ and scare us to death?&rdquo;
+ </p>
+ <p>
+ &ldquo;No,&rdquo; replied Mr. Parker, calmly, &ldquo;but there is every indication that we
+ will soon have a terrific electrical storm. From a high peak I caught a
+ glimpse of one working this way across the mountains.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'd better fasten the tent well down,&rdquo; called Tom. &ldquo;We don't want
+ it to blow away.&rdquo;
+ </p>
+ <p>
+ &ldquo;There will not be much danger from wind,&rdquo; was Mr. Parker's opinion.
+ </p>
+ <p>
+ &ldquo;From what then?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;From the discharges of lightning among these mountain peaks, which
+ contain so much iron ore. We will be in grave danger.&rdquo;
+ </p>
+ <p>
+ The fact that the scientist had not always made correct predictions was
+ not now considered by his hearers, and Tom and the two men gazed at Mr.
+ Parker in some alarm.
+ </p>
+ <p>
+ &ldquo;Is there anything we can do to avoid it?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;The only thing to do would be to leave the mountain,&rdquo; was the answer,
+ &ldquo;and, as the iron ore extends for miles, we can not get out of the danger
+ zone before the storm will reach us. It will be here in less than half an
+ hour.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'd better have supper,&rdquo; remarked Tom, practically, &ldquo;and get ready
+ for it. Perhaps it may not be as bad as Mr. Parker fears.&rdquo;
+ </p>
+ <p>
+ &ldquo;It will be bad enough,&rdquo; declared the gloomy scientist, and he seemed to
+ find pleasure in his announcement.
+ </p>
+ <p>
+ The meal was soon over, and Tom busied himself in looking to the guy ropes
+ of the tent, for he feared lest there might be wind with the storm. That
+ it was coming was evident, for now low mutterings of thunder could be
+ heard off toward the west.
+ </p>
+ <p>
+ Black clouds rapidly obscured the heavens, and the sound of thunder
+ increased. Fitful flashes of lightning could be seen forking across the
+ sky in jagged chains of purple light.
+ </p>
+ <p>
+ &ldquo;It's going to be a heavy storm,&rdquo; Tom admitted to himself. &ldquo;I hope
+ lightning doesn't strike around here.&rdquo;
+ </p>
+ <p>
+ The storm came on rapidly, but there was a curious quietness in the air
+ that was more alarming than if a wind had blown. The campfire burned
+ steadily, and there was a certain oppressiveness in the atmosphere.
+ </p>
+ <p>
+ It was now quite dark, save when the fitful lightning flashes came, and
+ they illuminated the scene brilliantly for a few seconds. Then, by
+ contrast, it was blacker than ever.
+ </p>
+ <p>
+ Suddenly, as Tom was gazing up toward the peak of Phantom Mountain, he saw
+ something that caused him to cry out in alarm. He pointed upward, and
+ whispered hoarsely:
+ </p>
+ <p>
+ &ldquo;The ghost again! There's our friend in white!&rdquo;
+ </p>
+ <p>
+ The others looked, and saw the same weird figure that had menaced them
+ when they were encamped on the other side of the peak.
+ </p>
+ <p>
+ &ldquo;They must have followed us,&rdquo; said Mr. Jenks, in a low voice.
+ </p>
+ <p>
+ Slowly the figure advanced, It waved the long white arms, as if in
+ warning. At times it would be only dimly visible in the blackness, then,
+ suddenly it would stand out in bold relief as a great flash of fire split
+ the clouds.
+ </p>
+ <p>
+ The thunder, meanwhile, had been growing louder and sharper, indicating
+ the nearer approach of the storm. Each lightning flash was followed in a
+ second or two, by a terrific clap. Still there was no wind nor rain, and
+ the campfire burned steadily.
+ </p>
+ <p>
+ All at once there was a crash as if the very mountain had split asunder,
+ and the adventurers saw a great ball of purple-bluish fire shoot down, as
+ if from some cloud, and strike against the side of the crag, not a hundred
+ feet from where stood the ghostly figure in white.
+ </p>
+ <p>
+ &ldquo;That was a bad one,&rdquo; cried Mr. Damon, shouting so as to be heard above
+ the echoes of the thunderclap.
+ </p>
+ <p>
+ Almost as he spoke there came another explosion, even louder than the one
+ preceding. A great ball of fire, pear shaped, leaped for the same spot in
+ the mountain.
+ </p>
+ <p>
+ &ldquo;There's a mass of iron ore there!&rdquo; yelled Mr. Parker. &ldquo;The lightning is
+ attracted to it!&rdquo;
+ </p>
+ <p>
+ His voice was swallowed up in the terrific crash that followed, and, as
+ there came another flash of the celestial fire, the figure in white could
+ be seen hurrying back up the mountain trail. Evidently the electrical
+ storm, with lightning bolts discharging so close, was too much for the
+ &ldquo;ghost.&rdquo;
+ </p>
+ <p>
+ In another instant it looked as if the whole place about where the diamond
+ seekers stood, was a mass of fire. Great forked tongues of lightning
+ leaped from the clouds, and seemed to lick the ground. There was a rattle
+ and bang of thunder, like the firing of a battery of guns. Tom and the
+ others felt themselves tingling all over, as if they had hold of an
+ electrical battery, and there was a strong smell of sulphur in the air.
+ </p>
+ <p>
+ &ldquo;We are in the midst of the storm!&rdquo; cried Mr. Parker. &ldquo;We are standing on
+ a mass of iron ore! Any minute may be our last!&rdquo;
+ </p>
+ <p>
+ But fate had not intended the adventurers for death by lightning. Almost
+ as suddenly as it had begun, the discharge of the tongues of fire ceased
+ in the immediate vicinity of our friends. They stood still&mdash;awed&mdash;not
+ knowing what to do.
+ </p>
+ <p>
+ Then, once more, came a terrific clap! A great mass of fire, like some
+ red-hot ingot from a foundry, was hurled through the air, straight at the
+ face of the mountain, and at the spot where the figure in white had stood
+ but a few minutes before.
+ </p>
+ <p>
+ Instantly the earth trembled, as it had at Earthquake Island, but it was
+ not the same. It was over in a few seconds. Then, as the diamond seekers
+ looked, they saw in the glare of a score of lightning flashes that
+ followed the one great clap, the whole side of the mountain slip away, and
+ go crashing into the valley below.
+ </p>
+ <p>
+ &ldquo;A landslide!&rdquo; cried Mr. Parker. &ldquo;That is the landslide which I predicted!
+ The lightning bolt has split Phantom Mountain!&rdquo;

+ <h2>
+ CHAPTER XVI&mdash;THE VAST CAVERN
+ </h2>
+ <p>
+ For a time the roiling, slipping, sliding and tumbling of the mass of
+ earth and stones, down the side of the mountain, effectually drowned all
+ other sounds. Even the thunder was stilled, and though Tom and his
+ companions called to one another in terror, their voices could not rise
+ above that terrific tumult.
+ </p>
+ <p>
+ Finally, when they found that the direction of the slide was away from
+ their tent, and that they were not likely to be engulfed, they grew more
+ calm.
+ </p>
+ <p>
+ Gradually the noise subsided. The great boulders had rolled to the bottom
+ of the valley, and now only a mass of earth and stones was sliding down.
+ Even this stopped in about five minutes, and, as though satisfied with
+ what it had done, the electrical storm passed. Not a drop of rain had
+ fallen.
+ </p>
+ <p>
+ &ldquo;Bless my shirt studs!&rdquo; exclaimed Mr. Damon, who was the first to speak
+ after the din had quieted. &ldquo;Bless my soul! But that was awful!&rdquo;
+ </p>
+ <p>
+ &ldquo;It was just what I expected,&rdquo; said Mr. Parker, calmly. &ldquo;I knew, from my
+ observations, that we were in a region where landslides and terrific
+ electrical storms may be expected at any time. I fully looked for this.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked Mr. Jenks, rather sarcastically, &ldquo;I hope it came up to
+ your expectations, Mr. Parker.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, fully,&rdquo; was the answer, &ldquo;though I wish it could have happened in
+ daylight, so that I could better have observed certain phenomena regarding
+ the landslide. They are very interesting.&rdquo;
+ </p>
+ <p>
+ &ldquo;At a distance,&rdquo; admitted Tom, with a laugh of relief. &ldquo;Well, I'm glad
+ it's over, though we'll have to wait until morning to see what damage has
+ been done. Lucky we weren't struck by lightning. I never saw such bolts!&rdquo;
+ </p>
+ <p>
+ &ldquo;Me, either!&rdquo; declared Mr. Damon. &ldquo;This mountain seems to attract them.&rdquo;
+ </p>
+ <p>
+ &ldquo;It is like a magnet,&rdquo; said Mr. Parker. &ldquo;I think I shall be able to make
+ some fine observations here.&rdquo;
+ </p>
+ <p>
+ &ldquo;If we live through it,&rdquo; murmured Mr. Jenks.
+ </p>
+ <p>
+ They watched the play of lightning about a distant bank of clouds, but the
+ storm was now far away, only a faint rumbling of thunder being heard.
+ </p>
+ <p>
+ &ldquo;I'm wondering what happened to the phantom,&rdquo; said Tom, after a pause.
+ &ldquo;Seems to me he was right in that track of the storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;Do you think it was a 'he'?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I think we'll find that it's some sort of a man,&rdquo; answered the young
+ inventor. &ldquo;We may find out very soon, now. I've changed my theory about
+ the ghost being reflections of light.&rdquo;
+ </p>
+ <p>
+ &ldquo;How's that?&rdquo; Mr. Damon wanted to know.
+ </p>
+ <p>
+ &ldquo;Well, I think we are on the side of Phantom Mountain where the diamond
+ cave is,&rdquo; went on the lad. &ldquo;The fact that the phantom appeared here, soon
+ after we arrived, shows that the men kept close track of our movements. It
+ also shows, I think, that the phantom did not have to travel far to be on
+ the spot, whereas we had to make quite a trip to get around the base of
+ the mountain. I think the cave is up there,&rdquo; and Tom pointed toward the
+ spot where the weird figure had been last seen, before the storm drove it
+ back.
+ </p>
+ <p>
+ &ldquo;There may be two phantoms,&rdquo; suggested Mr. Jenks. &ldquo;They may keep one on
+ this side of the mountain, and one on the other, to warn intruders away.
+ </p>
+ <p>
+ &ldquo;It's possible,&rdquo; admitted Tom. &ldquo;Well, we'll see how things look in the
+ morning, when we'll take up our march again, and go up the mountain. We'll
+ reach the top, if possible, which we couldn't do from the other side, as
+ it was too steep.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope we shall be able to go forward in the morning,&rdquo; came from Mr.
+ Jenks.
+ </p>
+ <p>
+ &ldquo;What do you mean?&rdquo; asked the lad, struck by a peculiar significance in
+ the diamond man's tones.
+ </p>
+ <p>
+ &ldquo;Why, that landslide may have opened a great gully in the side of Phantom
+ Mountain, which will prevent us from passing. It was a terrific lot of
+ earth and stones that slid away,&rdquo; answered Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;It certainly was,&rdquo; agreed Mr. Parker. &ldquo;I would not be surprised if the
+ mountain was half destroyed, and it may be that the diamond cave no longer
+ exists.&rdquo;
+ </p>
+ <p>
+ &ldquo;Not very cheerful, to say the least,&rdquo; murmured Mr. Jenks to Tom, and, as
+ it was getting quite chilly, following the storm, they went inside the
+ tent.
+ </p>
+ <p>
+ Tom could hardly wait for daylight, to get up and see what havoc the
+ landslide had wrought. As soon as the first faint flush of dawn showed
+ over the eastern peaks, he hurried from the tent. Mr. Damon heard him
+ arise, and followed.
+ </p>
+ <p>
+ A curious scene met their eyes. All about were great rocks rent and torn
+ by the awful power of the lightning. The fronts of the stone cliffs were
+ scarred and burned by the electrical fire, and fantastic markings,
+ grotesque faces, and leering animals seemed to have been drawn by some
+ gigantic artist who used a bolt from heaven for his brush.
+ </p>
+ <p>
+ But the eyes of Tom and Mr. Damon took all this in at a glance, and then
+ their gaze went forward to where the avalanche had torn away a great part
+ of the mountain.
+ </p>
+ <p>
+ &ldquo;Whew! I should say it was a landslide!&rdquo; cried Tom.
+ </p>
+ <p>
+ &ldquo;Bless my wishbone, yes!&rdquo; agreed Mr. Damon.
+ </p>
+ <p>
+ Below them, in the valley, lay piled immense masses of earth and stones.
+ Boulders were heaped up on boulders, and rocks upon rocks, being tossed
+ about in heaps, strung about in long ridges, and swirled about in curves,
+ as though some cyclone had toyed with them after the lightning flash had
+ tossed them there.
+ </p>
+ <p>
+ &ldquo;But the mountain isn't half gone,&rdquo; said Tom, as his eyes took in what was
+ left of the phantom berg. &ldquo;I guess it will take a few more bolts like that
+ one, to put this hill out of business.&rdquo;
+ </p>
+ <p>
+ Though the landslide had been a great one, the larger part of the mountain
+ still stood. An immense slice had been taken from one side, but the summit
+ was untouched.
+ </p>
+ <p>
+ &ldquo;And there's where the diamond cave is!&rdquo; cried Tom, pointing to it.
+ </p>
+ <p>
+ &ldquo;I think so myself,&rdquo; agreed Mr. Jenks, who came from the tent at that
+ moment, and joined the lad and Mr. Damon. &ldquo;I think we shall find the cave
+ somewhere up there. We must start for it, as soon as we have eaten, and we
+ may reach it by night.&rdquo;
+ </p>
+ <p>
+ The three stood gazing up toward the summit of the great mountain.
+ Suddenly, as the sun rose higher in the heavens, it sent a shaft of rosy
+ light on the face of the berg that had been scarred by the landslide. Tom
+ Swift uttered an exclamation, and pointed at something.
+ </p>
+ <p>
+ &ldquo;See!&rdquo; he cried. &ldquo;Look where the trail is&mdash;the trail down which the
+ phantom must have come. It is on the edge of a cliff now!&rdquo;
+ </p>
+ <p>
+ They looked, and saw that this was so. The increasing light had just
+ revealed it to them. When the lightning bolt had torn away a great portion
+ of the mountain it had cut sheer down for a great depth and when the earth
+ and stones fell away they left a narrow pathway, winding around the
+ mountain, but so near the edge of a great chasm, that there was room but
+ for one person at a time to walk on that footway. The uncertain trail up
+ Phantom Mountain had all but been destroyed.
+ </p>
+ <p>
+ &ldquo;The way up to the peak is by that path, now,&rdquo; spoke Tom, in a low voice.
+ </p>
+ <p>
+ &ldquo;Bless my soul!&rdquo; cried Mr. Damon. &ldquo;It's as much as a man's life is worth
+ to attempt it. If he got dizzy, he'd topple over, and fall a thousand
+ feet. Dare we risk it?&rdquo;
+ </p>
+ <p>
+ &ldquo;It's the only way to get up,&rdquo; went on Tom. &ldquo;It's either that way, or not
+ at all. We've tried the other side without success. We must go up this way&mdash;or
+ turn back.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'll go up!&rdquo; cried Mr. Jenks. &ldquo;It may not be as dangerous as it
+ looks from here.&rdquo;
+ </p>
+ <p>
+ But it was even more dangerous than it appeared, when they went part way
+ up it after a hasty breakfast. The trail was a mere ledge of rock now, and
+ in some places, to get around a projecting edge of the mountain, they had
+ to stand with their backs to the dizzy depths at their feet, and with both
+ arms outstretched work their way around to where the trail was wider.
+ </p>
+ <p>
+ &ldquo;Shall we risk it?&rdquo; asked Tom, when they had tried the way, and found it
+ so dangerous. &ldquo;We can't take anything with us&mdash;even our guns, for we
+ couldn't carry them, and if we reach the mouth of the cave, and find those
+ men there&mdash;&rdquo;
+ </p>
+ <p>
+ He paused significantly. The adventurers looked at one another. The search
+ for the diamond makers was becoming more and more dangerous.
+ </p>
+ <p>
+ &ldquo;I say let's go on!&rdquo; decided Mr. Damon, suddenly. &ldquo;We want to locate that
+ cave, first of all. Perhaps, when we do find it, we may see some easier
+ way of getting to it than this. And if those diamond makers do attack us&mdash;well,
+ I don't believe they'll shoot defenseless men, and they may listen to
+ reason, and give Mr. Jenks his rights&mdash;tell him how to make diamonds
+ in return for the money he gave them.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't believe those scoundrels will listen to reason,&rdquo; replied the
+ diamond man, &ldquo;but I agree with Mr. Damon that we ought to go on. We may
+ find some other means of reaching the cave&mdash;if we can discover it,
+ and we'll take a chance with the men.&rdquo;
+ </p>
+ <p>
+ &ldquo;Forward it is, then!&rdquo; cried Tom. &ldquo;I have a revolver, and I can supply one
+ of you gentlemen with another. They may come in useful in an emergency.
+ Let's go back to camp, take a little lunch in our pockets, and try to
+ scale the mountain.&rdquo;
+ </p>
+ <p>
+ They were soon on their way up the dizzy path once more, and, as they
+ advanced, they found it growing more and more dangerous. In some places
+ they found it almost impossible to get around certain corners, where there
+ was barely room for their feet. As Tom remarked grimly, a fat man never
+ could have done it. Fortunately they were all comparatively thin, for
+ their hard work, and not too abundant food, since they had left the
+ airship, had reduced their weight.
+ </p>
+ <p>
+ Up and up they went, higher and higher, sometimes finding the path wide
+ enough for two to walk abreast, and again seeing it narrow almost to a
+ ribbon. They hardly dared look down into the chasm at their left&mdash;a
+ chasm filled, in part, with the rocks and boulders tossed into it by the
+ lightning bolt.
+ </p>
+ <p>
+ Tom was in the lead, and had just made a dangerous turn around a shoulder
+ of rock&mdash;one of those places where he had to extend both arms, and
+ fairly hug the cliff before he could get around.
+ </p>
+ <p>
+ But, when he had made it, and found himself on a broad pathway, cut in the
+ living rock, he gave a great shout&mdash;a shout that caused his
+ companions to hasten to his side. They found the young inventor pointing
+ to a clump of bushes and small trees.
+ </p>
+ <p>
+ But it was not the shrubbery that Tom desired to call to their attention.
+ They saw that in an instant, for, dimly seen through the leaves, was
+ something black, and, as they looked more closely, they saw that it was a
+ great hole in the side of the mountain&mdash;a vast cavern, opening like a
+ tunnel.
+ </p>
+ <p>
+ &ldquo;The cave! The cave!&rdquo; cried Tom. &ldquo;The diamond makers' cave!&rdquo;
+ </p>
+ <p>
+ Hardly had he spoken than two men, each one carrying a gun, showed
+ themselves in the mouth of the cavern, and, instant later they both ran
+ toward the little party of adventurers.

+ <h2>
+ CHAPTER XVII&mdash;THE PHANTOM CAPTURED
+ </h2>
+ <p>
+ Surprise held Tom and his friends almost spellbound for the moment. The
+ young inventor's hand went toward the pocket where he carried his
+ revolver. Mr. Jenks, who had the only other weapon, sought to draw it, but
+ he was stopped by a gesture of one of the two men with guns.
+ </p>
+ <p>
+ &ldquo;Hold on, strangers!&rdquo; the man cried. &ldquo;I know what you're up to! Better not
+ try to draw anything&mdash;it might not be healthy. Now, then, who are
+ you, and what do you want?&rdquo;
+ </p>
+ <p>
+ The question came rather as a surprise, at least to Tom and Mr. Jenks.
+ They had taken it for granted that these men&mdash;if they were the
+ diamond makers&mdash;would know Mr. Jenks, and guess at his errand in
+ coming back to Phantom Mountain. But, it seemed, that they took them all
+ for casual strangers.
+ </p>
+ <p>
+ No one answered for a moment. Tom caught the eye of Mr. Jenks, and there
+ was a look of hope in it. If ever there was a time for strategy, it was
+ now. Evidently Munson, the stowaway on the airship, had not yet been able
+ to send a warning to his confederates. And neither of the two men
+ recognized Mr. Jenks as the man who had been defrauded of his rights. It
+ might be possible to conceal the real object of the adventurers until they
+ had time to formulate a plan of action.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; exclaimed the man with the gun, impatiently, &ldquo;I ask you folks a
+ question. What do you want?&rdquo;
+ </p>
+ <p>
+ Fortunately, neither Mr. Damon nor Mr. Parker replied. The former because
+ he deferred to Tom and Mr. Jenks, and the scientist because he was busy
+ inspecting some curious rocks he picked up. As it turned out this was the
+ luckiest thing he could have done. It lent color to what Mr. Jenks said a
+ moment later.
+ </p>
+ <p>
+ &ldquo;What are you doing up here?&rdquo; demanded the man again. &ldquo;Don't you know this
+ is private property?&rdquo;
+ </p>
+ <p>
+ &ldquo;We&mdash;we were just looking around,&rdquo; answered Mr. Jenks, which was true
+ enough; as far as it went.
+ </p>
+ <p>
+ &ldquo;Prospecting,&rdquo; added Tom.
+ </p>
+ <p>
+ &ldquo;After gold?&rdquo; demanded the second man, suspiciously.
+ </p>
+ <p>
+ &ldquo;We'd be glad to find some,&rdquo; retorted the lad. At that moment Mr. Parker
+ began breaking off bits of rock with a small geologist's hammer which he
+ carried. The men with the guns looked at him.
+ </p>
+ <p>
+ &ldquo;So you think you'll find gold up here?&rdquo; asked the one who had first
+ spoken.
+ </p>
+ <p>
+ &ldquo;Is there any?&rdquo; inquired Tom, trying to make his voice sound eager.
+ </p>
+ <p>
+ &ldquo;Nary a bit, strangers,&rdquo; was the answer, and the two men laughed heartily.
+ &ldquo;Now, we don't want to seem harsh,&rdquo; went on the man who seemed to be the
+ spokesman, &ldquo;but you'd better get away from here. This is private ground,
+ and dangerous too&mdash;how'd you ever get up the trail&mdash;we heard it
+ was destroyed.&rdquo;
+ </p>
+ <p>
+ &ldquo;There is still a narrow path,&rdquo; said Mr. Jenks. &ldquo;We came up that&mdash;the
+ lightning and landslide haven't left much of it, though.&rdquo;
+ </p>
+ <p>
+ Mr. Parker looked quickly up from the rocks at which he was tapping with
+ his small hammer. &ldquo;You have terrific lightning up here,&rdquo; he said. &ldquo;I am
+ much interested in it, from a scientific standpoint. I predict that some
+ day the entire mountain will be destroyed by a blast from the sky.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope it won't be right away,&rdquo; spoke one of the men. &ldquo;Now I guess you
+ folks had better be leaving while there's a path left to go down by.&rdquo;
+ </p>
+ <p>
+ &ldquo;Might I ask,&rdquo; broke in Mr. Parker, as calmly as though he was lecturing
+ to a class of students, &ldquo;might I ask if you have noticed any peculiar
+ effect of the lightning up here on the summit of the mountain? Does it
+ fuse and melt rocks, so to speak?&rdquo;
+ </p>
+ <p>
+ &ldquo;What's that?&rdquo; cried the spokesman, with a sudden flash of anger. The two
+ men looked at each other.
+ </p>
+ <p>
+ &ldquo;I wanted to know, merely for scientific reasons, whether the lightning up
+ here ever melted rocks?&rdquo; repeated Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Well, whether it's for scientific reasons or for any other, I'm not going
+ to answer you!&rdquo; snapped the man. &ldquo;It's none of your affair what the
+ lightning does up here. Now you'd all better 'vamoose'&mdash;clear out!&rdquo;
+ </p>
+ <p>
+ &ldquo;All right&mdash;we'll go,&rdquo; said Tom, quickly, at the same time motioning
+ to Mr. Jenks to agree with him. The eyes of the young inventor were roving
+ about. He saw what looked like a second trail, leading down the mountain,
+ from the far side of the cave. He was convinced now that there was another
+ way to get to it. Possibly they might find it. At any rate nothing more
+ could be done now. They must go back, for the cavern was too well guarded
+ to attempt to enter it by force&mdash;at least just yet.
+ </p>
+ <p>
+ &ldquo;Yes, we'll go back,&rdquo; assented Mr. Jenks.
+ </p>
+ <p>
+ Mr. Parker was tapping away at the rocks. He looked toward the black mouth
+ of the big cave. On what corresponded to the roof of it, some distance
+ back from the entrance, he saw a slender metal rod sticking up into the
+ air.
+ </p>
+ <p>
+ &ldquo;May I ask if that's a lightning rod?&rdquo; he inquired innocently. &ldquo;If it is,
+ I should like to ask about its action in a mountain that is so impregnated
+ with iron ore.
+ </p>
+ <p>
+ &ldquo;You may ask until you get tired!&rdquo; cried the spokesman, again showing
+ unreasoning anger, &ldquo;but you'll get no answer from us. Now get away from
+ here before we do something desperate. You're on private ground and you're
+ not wanted. Clear out while you have the chance.&rdquo;
+ </p>
+ <p>
+ There was no help for it. Slowly our friends turned and began to go down
+ the dangerous trail. They were soon out of sight of the two men who stood
+ before the cave, with their guns ready, but neither Tom nor any of his
+ companions spoke for some time.
+ </p>
+ <p>
+ When they had rounded one of the most dangerous turns the young inventor
+ sat down to rest, an example followed by the others.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; asked Tom, &ldquo;do you think those are some of the diamond makers, Mr.
+ Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;I certainly do, though I never saw those two men before. If I could once
+ get inside the cave, I could tell whether or not it was the one where I
+ was practically held a prisoner. But I'm sure it is. I know some of the
+ men used to go off every day with guns, and not come back until night. I
+ have no doubt they were on guard, just as these two are. And, also, I
+ think I heard them speak of a second entrance to the cavern. The one we
+ just saw may not be the main one, through which I was taken.&rdquo;
+ </p>
+ <p>
+ &ldquo;I believe we are on the right track,&rdquo; ventured Mr. Damon, &ldquo;but we will
+ either have to go up there after dark, which will be risky, on account of
+ the narrow trail, or else we will have to find some other path.&rdquo;
+ </p>
+ <p>
+ &ldquo;The last would be better,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;That rod of metal sticking up on top of the cave interested me,&rdquo; said the
+ scientist. &ldquo;Did you hear anything of that when you were here before, Mr.
+ Jenks?&rdquo;
+ </p>
+ <p>
+ &ldquo;No. Probably that is only a lightning rod, or it may be a staff for a
+ signal flag. But what surprises me is that those men didn't suspect that
+ we were seeking to discover their secret. They took us for ordinary
+ prospectors.&rdquo;
+ </p>
+ <p>
+ &ldquo;So much the better,&rdquo; remarked Tom. &ldquo;We have a chance now of getting
+ inside that cave. But we will have to go back to camp, and make other
+ plans. And we must hurry, or it will be dark before we get there.&rdquo;
+ </p>
+ <p>
+ They hastened their steps, pausing only briefly to eat some of the lunch
+ they had brought along, and to drink from a spring that bubbled from the
+ side of the mountain. It was getting dusk when they got back to their
+ tent. They found nothing disturbed.
+ </p>
+ <p>
+ &ldquo;I wonder if we'll see that phantom again to-night?&rdquo; ventured Tom, as they
+ were sitting about the campfire a little later.
+ </p>
+ <p>
+ &ldquo;Probably not,&rdquo; remarked Mr. Jenks. &ldquo;I don't believe the ghost will
+ venture down the dangerous trail after dark, and the gang may think that
+ the warning given us by the two men on guard at the cave will be
+ sufficient. But if we don't leave here by to-morrow I think we will have
+ another visit from the thing in white.&rdquo;
+ </p>
+ <p>
+ It was about an hour after this when Tom was collecting some wood in a
+ pile nearer the fire, so as to have it ready to throw on, in case there
+ was any alarm in the night, that he happened to look up toward the summit
+ of the mountain. A slight noise, as of loose stones rolling down,
+ attracted his attention, and, at first, he feared lest another landslide
+ was beginning, but a moment later he saw what caused it.
+ </p>
+ <p>
+ There, advancing down the steep and dangerous trail was the figure in
+ white&mdash;the phantom. Instantly a daring plan came into Tom's head.
+ Dropping the wood softly, he moved back out of the glare of the fire.
+ </p>
+ <p>
+ &ldquo;Mr. Jenks!&rdquo; he called in a whisper.
+ </p>
+ <p>
+ The diamond man, who was behind the tent, came toward Tom.
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; he asked. Then, as he saw the ghostly visitor, he added: &ldquo;Oh&mdash;the
+ phantom again! What's it up to?&rdquo;
+ </p>
+ <p>
+ &ldquo;The same thing,&rdquo; replied Tom, &ldquo;but it won't do it long, if my plan
+ succeeds.&rdquo;
+ </p>
+ <p>
+ &ldquo;What plan is that, Tom?&rdquo;
+ </p>
+ <p>
+ &ldquo;I'm going to try to capture that&mdash;that man&mdash;or whatever it is.
+ Will you help?&rdquo;
+ </p>
+ <p>
+ &ldquo;Surely!&rdquo;
+ </p>
+ <p>
+ &ldquo;Then let's work around behind it, while Mr. Damon and Mr. Parker come up
+ from in front. We'll solve this part of the mystery, anyhow, if it's
+ possible!&rdquo;
+ </p>
+ <p>
+ The two other men were soon told of the plan. Meanwhile the thing in white
+ had advanced slowly, until within a few hundred feet of the camp. They
+ could see now that it was no shaft of light, but some white body, shaped
+ like a tall, thin man, draped in a white garment. The long arms waved to
+ and fro. There was no semblance of a head.
+ </p>
+ <p>
+ &ldquo;You and Mr. Parker go right toward it, slowly, Mr. Damon,&rdquo; advised Tom.
+ &ldquo;Mr. Jenks and I will make a circle, and get in back. Then, if it's
+ anything alive we'll have it.&rdquo;
+ </p>
+ <p>
+ The &ldquo;ghost&rdquo; continued to advance. Tom and the diamond man stole off to one
+ side, their buckskin moccasins making no sound. Mr. Damon and the
+ scientist went boldly forward.
+ </p>
+ <p>
+ This movement appeared to disconcert the spirit. It halted, waved the arms
+ with greater vigor than before, and seemed to indicate to the adventurers
+ that it was dangerous to advance. But Mr. Damon and Mr. Parker kept on.
+ They wanted to give Tom and Mr. Jenks time enough to make the circuit.
+ </p>
+ <p>
+ Suddenly the stillness of the night was broken by a low whistle. It was
+ Tom's signal that he and Mr. Jenks were ready.
+ </p>
+ <p>
+ &ldquo;Come on! Run!&rdquo; cried Mr. Damon.
+ </p>
+ <p>
+ The scientist and the eccentric man leaped forward.
+ </p>
+ <p>
+ The &ldquo;ghost&rdquo; heard the whistle, and heard the spoken words. The thing in
+ white hesitated a moment, and then raised one arm. There was a flash of
+ fire, and a loud report.
+ </p>
+ <p>
+ &ldquo;He's firing in the air!&rdquo; cried Tom. &ldquo;Come on, we have him now!&rdquo;
+ </p>
+ <p>
+ Undaunted by the display of firearms, Mr. Damon and Mr. Parker kept on.
+ They could hear Tom and Mr. Jenks running up in back of the figure. The
+ latter also heard this, and suddenly turned. Caught between the two forces
+ of our friends, the &ldquo;ghost&rdquo; was at a loss what to do.
+ </p>
+ <p>
+ The next instant Tom, who had distanced Mr. Jenks, made a flying tackle
+ for the figure in white, and caught it around the legs. Very substantial
+ legs they were, too, Tom felt&mdash;the legs of a man.
+ </p>
+ <p>
+ &ldquo;Wow!&rdquo; yelled the &ldquo;ghost,&rdquo; as he went down in a heap, the revolver falling
+ from his hand.
+ </p>
+ <p>
+ &ldquo;Come on!&rdquo; cried Tom. &ldquo;I have him!&rdquo;
+ </p>
+ <p>
+ His friends rushed to his aid. There was a confused mass of dark bodies,
+ arms and legs mingled with something tall and thin, all in white. Suddenly
+ the moon came from behind a cloud and they could see what they had
+ captured&mdash;for captured the phantom was.
+ </p>
+ <p>
+ It proved to be a rather small man, who wore upon his shoulders a
+ framework of wood, over which some white cloth was draped. It had fallen
+ off him when Tom made that tackle.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked the young inventor, as he sat on the struggling man's
+ chest. &ldquo;I guess we've got you.&rdquo;
+ </p>
+ <p>
+ &ldquo;I rather guess you have, stranger,&rdquo; was the cool reply.

+ CHAPTER XVIII&mdash;BILL RENSHAW WILL HELP
+ </h2>
+ <p>
+ They were all panting from the exertion of the run up the mountain and the
+ contest with the phantom&mdash;a phantom no longer&mdash;though, truth to
+ tell, the struggle was not nearly so fierce as Tom had expected. He
+ thought the &ldquo;ghost&rdquo; would put up a stiff fight.
+ </p>
+ <p>
+ &ldquo;Got any ropes to tie him with?&rdquo; asked Mr. Damon, who was helping Tom hold
+ the man down.
+ </p>
+ <p>
+ &ldquo;Ropes? You aren't going to tie me up are you, strangers?&rdquo; asked the
+ captive.
+ </p>
+ <p>
+ &ldquo;That's what we are!&rdquo; exclaimed Mr. Jenks. &ldquo;We've had trouble enough in
+ this matter, and if I've got one of the gang, perhaps I can get some of
+ the others, and have my rights. So tie him up, Tom, and we'll take him to
+ camp.
+ </p>
+ <p>
+ &ldquo;Oh, you needn't go to all that trouble, strangers,&rdquo; went on the man,
+ calmly. &ldquo;If one of you will get off my chest, and the other gentleman ease
+ up on my stomach a bit, I'll walk wherever you want me, and not make any
+ trouble. I haven't got a gun.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my gloves! But you're a cool one,&rdquo; commented Mr. Damon, as he
+ complied with the man's request, and got up from his stomach. &ldquo;But look
+ out for him, Tom. He had a gun, for he fired it in the air.&rdquo;
+ </p>
+ <p>
+ &ldquo;He hasn't it now,&rdquo; answered the young inventor. &ldquo;I knocked it from his
+ hand when I leaped for him.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's what you did,&rdquo; assented the man, as he got up, while Tom kept a
+ tight hold of him, as did Mr. Jenks. &ldquo;What kind of a grizzly bear hug do
+ you call that, anyhow, that you gave me?&rdquo;
+ </p>
+ <p>
+ &ldquo;That was a football tackle,&rdquo; explained Tom.
+ </p>
+ <p>
+ &ldquo;I allers heard that was a dangerous game!&rdquo; remarked the former phantom
+ simply. &ldquo;Well, now you've got me, what are you going to do with me?&rdquo;
+ </p>
+ <p>
+ &ldquo;Take you where we can have a good look at you,&rdquo; replied Mr. Jenks, as he
+ kicked aside the wooden framework, and the sheet which had made the
+ &ldquo;ghost&rdquo; appear so tall. &ldquo;So this is how you worked it; eh?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yep. That was the 'haunt' stranger. I made it myself, and it worked all
+ right until you folks come along. I rather suspicioned from the first,
+ when I played the trick over on 'tother side of the mountain, that you
+ wouldn't be so easy to fool as most prospectors are.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, so you're the only ghost then?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I'm the only one.&rdquo;
+ </p>
+ <p>
+ By this time they had reached the camp. Tom threw some light logs on the
+ fire, which blazed up brightly. As the flames illuminated the face of
+ their captive, Mr. Jenks looked at him, and cried out:
+ </p>
+ <p>
+ &ldquo;Why it's Bill Renshaw!&rdquo;
+ </p>
+ <p>
+ &ldquo;That's me,&rdquo; admitted the man who had played the part of the phantom, &ldquo;and
+ thunder-turtles! if it ain't Mr. Jenks who was once in the diamond cave
+ with us. Whatever happened to you? I never heard. The others said you got
+ tired and went away.&rdquo;
+ </p>
+ <p>
+ &ldquo;They took me away&mdash;defrauded me of my rights!&rdquo; declared Mr. Jenks,
+ bitterly. &ldquo;But I'll get them back! To think of Bill Renshaw playing the
+ part of a ghost!&rdquo;
+ </p>
+ <p>
+ &ldquo;They made me do it,&rdquo; went on the man, somewhat dejectedly. &ldquo;I wanted to
+ be at work in the cave, but they wouldn't let me.&rdquo;
+ </p>
+ <p>
+ &ldquo;Is this man one of the diamond makers?&rdquo; asked Tom, in great surprise.
+ </p>
+ <p>
+ &ldquo;He is&mdash;one of the helpers, though I don't believe he knows the
+ secret of making the gems,&rdquo; explained Mr. Jenks. &ldquo;He was one of the men in
+ the cave when I was there before, and he and I struck up quite a
+ friendship; didn't we, Renshaw?&rdquo;
+ </p>
+ <p>
+ &ldquo;That's what, and there ain't no reason why we can't be friends now; that
+ is unless you hold a grudge against me for firing at you. But I only shot
+ in the air, to scare you away. Them's my instructions. I'm supposed to be
+ on guard, and scare away strangers. I'm tired of the work, too, for I
+ don't get my share, and those other fellows, in the cave, get all the
+ money from the diamonds.&rdquo;
+ </p>
+ <p>
+ Tom Swift uttered an exclamation. A sudden plan had come to him. Quickly
+ he whispered to Mr. Jenks:
+ </p>
+ <p>
+ &ldquo;Make a friend of this man if possible. He evidently is dissatisfied.
+ Offer him a sum to show us another way into the cave, and we may yet
+ discover the secret of the diamond makers.&rdquo;
+ </p>
+ <p>
+ &ldquo;I will,&rdquo; declared Mr. Jenks, quietly. Then, turning to Renshaw, he added:
+ </p>
+ <p>
+ &ldquo;Bill, come over here. I want to have a talk with you. Perhaps it will be
+ to our mutual advantage.&rdquo;
+ </p>
+ <p>
+ He led the former phantom to one side, and for some time conversed
+ earnestly with him. Mr. Jenks told the story of how he had been deceived
+ by Folwell and the others who were at the head of the gang of diamond
+ makers. The rich man related how they had taken his money, and, after
+ promising to disclose the secret process to him, had broken faith, and had
+ drugged him, afterward taking him out of the cave.
+ </p>
+ <p>
+ &ldquo;I want only my rights, and that for which I paid,&rdquo; concluded Mr. Jenks.
+ &ldquo;Now, I gather that these men haven't treated you altogether fairly,
+ Bill.&rdquo;
+ </p>
+ <p>
+ &ldquo;Indeed they haven't. I helped 'em to the best of my ability, and all I
+ get out of it is to stay out on this lonely side of the mountain, and play
+ ghost. They owe me money, too, and they won't pay me, either, though they
+ have lots, for they sold some diamonds lately.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then they are still making diamonds?&rdquo; asked Mr. Jenks, eagerly. &ldquo;Have you
+ seen them? Do you know the secret?&rdquo;
+ </p>
+ <p>
+ &ldquo;No, I don't know it, for they won't let me in on it. I'm always sent out
+ of the cave just before they make the gems. But I know they've made some
+ lately, and have sold 'em. I want my share.&rdquo;
+ </p>
+ <p>
+ &ldquo;Look here!&rdquo; exclaimed Mr. Jenks, quickly, wishing to strike while the
+ iron was hot. &ldquo;I'll make you a proposition. Show us how to get into that
+ cave, unknown to the diamond makers, and I'll pay you twice what they
+ agreed to. Is it a bargain?&rdquo;
+ </p>
+ <p>
+ Bill Renshaw considered a moment. Then he thrust out his hand, clasped
+ that of Mr. Jenks, and exclaimed:
+ </p>
+ <p>
+ &ldquo;It is. I'll take you into the cave by an entrance that's seldom used.
+ There are four ways to get in. The one where the two men drove you back is
+ the rear one. The front one is on the other side of the mountain, but it's
+ so well concealed that you'd never find it. But I can take you to one
+ where you can get in, and those fellows will never know it. And, what's
+ more, I'll help you if it comes to a fight!&rdquo;
+ </p>
+ <p>
+ &ldquo;Good!&rdquo; exclaimed Mr. Jenks. &ldquo;I think we'll discover the secret of the
+ diamond makers this time,&rdquo; and he went to tell the others of the success
+ of his talk. Bill Renshaw had been converted from an enemy into a friend,
+ and the former phantom was now ready to lead Tom and the others into the
+ secret cave.
+ </p>
+ <p>
+ &ldquo;We'll start in the morning,&rdquo; decided Mr. Jenks, who, after many
+ disappointments, at last saw success ahead of him.

+ <h2>
+ CHAPTER XIX&mdash;IN THE SECRET CAVE
+ </h2>
+ <p>
+ Tom Swift was up at break of day, and the others were not far behind him.
+ </p>
+ <p>
+ &ldquo;Now for the secret cave!&rdquo; cried the young inventor as he gazed up the
+ mountain, in the interior of which the mysterious band of men were making
+ the diamonds.
+ </p>
+ <p>
+ &ldquo;Have you made any plans, Bill?&rdquo; asked Mr. Jenks of the former phantom,
+ who had cast his lot in with the adventurers. &ldquo;What will be the best
+ course for us to follow?&rdquo;
+ </p>
+ <p>
+ &ldquo;You just leave it to me, Mr. Jenks,&rdquo; was the answer. &ldquo;I'll get you into
+ the cave, and those fellows, who, I believe, are trying to do me out of my
+ rights, as they did you out of yours, will never know a thing about it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my finger-nails!&rdquo; cried Mr. Damon. &ldquo;That will be great! We can get
+ in the cave, and watch them make the diamonds at our leisure.&rdquo;
+ </p>
+ <p>
+ &ldquo;They don't make them every day,&rdquo; explained Renshaw. &ldquo;It seems they have
+ to wait for certain occasions. Mostly they make the diamonds when there's
+ a big storm.&rdquo;
+ </p>
+ <p>
+ &ldquo;A big storm,&rdquo; asked the scientist with a sudden show of interest. &ldquo;Do you
+ mean one of those electrical storms, such as we had the other night?&rdquo;
+ </p>
+ <p>
+ &ldquo;That's it, Mr. Parker, though why they wait until there's a storm is more
+ than I can tell.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps they know that on such occasions no one will venture up the
+ mountain,&rdquo; spoke Mr. Damon.
+ </p>
+ <p>
+ &ldquo;No, it isn't that,&rdquo; declared the scientist. &ldquo;I think I am on the track of
+ a great scientific discovery, and I will soon be able to make observations
+ that will confirm it.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I'm going to make an observation right now,&rdquo; said Tom, with a
+ laugh. &ldquo;I'm going to see what there is for breakfast.&rdquo;
+ </p>
+ <p>
+ &ldquo;And that reminds me,&rdquo; came from Mr. Jenks, &ldquo;shall we move our camp, Bill,
+ and take the tent with us to the cave?&rdquo;
+ </p>
+ <p>
+ &ldquo;I hardly think so,&rdquo; was the answer. &ldquo;I think the best plan would be to
+ conceal the tent somewhere around here, in case you might need it again.
+ You can also store what food you have left.&rdquo;
+ </p>
+ <p>
+ &ldquo;But, bless my appetite, we don't want to starve in that diamond cave!&rdquo;
+ objected Mr. Damon.
+ </p>
+ <p>
+ &ldquo;I'll see that you don't,&rdquo; declared Bill Renshaw. &ldquo;I'll take you in there,
+ unbeknownst to those fellows, and I'll provide you with plenty of food and
+ water. You see the cave is so big that there are some parts they never
+ visit.&rdquo;
+ </p>
+ <p>
+ &ldquo;And we can stay in one of those parts, and eat?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Sure,&rdquo; answered Bill.
+ </p>
+ <p>
+ &ldquo;And watch the diamond makers at work?&rdquo; asked Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;That's it,&rdquo; replied the former phantom.
+ </p>
+ <p>
+ &ldquo;Then the sooner we get started the better,&rdquo; remarked Mr. Damon. Mr.
+ Parker said nothing. He appeared to be thinking deeply, and was tapping at
+ some rocks with his little hammer.
+ </p>
+ <p>
+ The advice of Bill Renshaw was followed, and the tent, and what food
+ remained, was concealed in the bushes, with rocks piled over to keep away
+ prowling animals. Then they started for the secret cave.
+ </p>
+ <p>
+ The man who played the part of a ghost picked up the framework and white
+ cloth that had formed his disguise.
+ </p>
+ <p>
+ &ldquo;I'll still have to use this,&rdquo; he explained, &ldquo;for I don't want those
+ fellows to know that I'm helping you. I'll continue to play the spirit of
+ the mountain, but there won't be much need of it. I don't think any more
+ people will come prospecting out here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Have you heard of the arrival of Farley Munson?&rdquo; asked Tom, as he related
+ the facts about the stowaway.
+ </p>
+ <p>
+ &ldquo;He hadn't arrived up to a day or so ago,&rdquo; answered Bill. &ldquo;I guess he's
+ still traveling. Farley is one of the heads of the gang,&rdquo; he added, &ldquo;and a
+ dangerous man.&rdquo;
+ </p>
+ <p>
+ As Bill led the way toward the cave, taking a route that the adventurers
+ had never suspected led to it, he explained that the cavern was a large
+ one, capable of holding an army.
+ </p>
+ <p>
+ &ldquo;But there's only a small part of it used by the diamond makers,&rdquo; he
+ added. &ldquo;They work in a small recess, near the summit of the mountain. The
+ little cave, where I'm going to take you, opens off from it by a long
+ passage. And, except that you'll be pretty much in the dark, you'll be
+ quite comfortable. There are tables, chairs, and some bunks in the place.
+ I can get you some lights, and plenty of food.&rdquo;
+ </p>
+ <p>
+ &ldquo;But, if you are seen taking away food, won't the others suspect
+ something?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I do pretty much as I please,&rdquo; said Bill. &ldquo;I go and come when I like. All
+ I'm supposed to do is to watch my two sides of the mountain, play the
+ ghost, and give warning when any one is coming. Sometimes I leave black
+ and white messages, like the one I put on your tent. Those fellows fix 'em
+ up for me. I've told 'em about you, though I didn't know who you were, and
+ they think you have gone, for the two men on guard at the rear entrance so
+ reported. Sometimes I stay out on the mountain for a couple of days at a
+ time, when the weather's good, and don't go back to the cave. Those times
+ I take food with me, and so if they see me making off with some supplies
+ they'll think I'm going to camp out.&rdquo;
+ </p>
+ <p>
+ &ldquo;It doesn't look as though we'd ever get into a cave near the top of the
+ mountain, going this way,&rdquo; said Tom, as they marched along. &ldquo;We're going
+ down, instead of up.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's the secret of this trail,&rdquo; explained Bill. &ldquo;We go down in a sort
+ of valley, and then go up a pretty stiff place, and then we're on a direct
+ trail to the entrance I told you about. It's a steep road to climb, but I
+ guess we can manage it.&rdquo;
+ </p>
+ <p>
+ And a hard climb the adventurers did find it. The road was almost as bad
+ as the one along the edge of the chasm, but they managed to negotiate it,
+ and finally found themselves on a fairly good trail.
+ </p>
+ <p>
+ &ldquo;We'll soon be there,&rdquo; Bill assured them. &ldquo;After you get in the little
+ cave, where I'm going to hide you, I'll have to leave you for a spell,
+ until I get my ghost rigging fixed up again. But I'll see that you have
+ plenty of food and drink.&rdquo;
+ </p>
+ <p>
+ A little later their guide came to a sudden halt, and peered around
+ anxiously.
+ </p>
+ <p>
+ &ldquo;What's the matter?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I was just looking to see if any of the men were about,&rdquo; he answered.
+ &ldquo;But I guess not&mdash;it looks all right. The entrance is right here.&rdquo;
+ </p>
+ <p>
+ They were on a side of the mountain, near the summit. Below stretched a
+ magnificent scene. A great valley lay at their feet, and they could look
+ off to many distant peaks. The main trail to Leadville, and the one to the
+ settlement of Indian Ridge, was in sight.
+ </p>
+ <p>
+ Suddenly Tom, who had been using a small but powerful telescope, uttered
+ an exclamation, and focussed the instrument on a speck that seemed moving
+ along on the trail below.
+ </p>
+ <p>
+ &ldquo;A man&mdash;coming up the mountain,&rdquo; cried Tom. &ldquo;And&mdash;it can't be&mdash;yet
+ it is&mdash;it's Farley Munson&mdash;the stowaway!&rdquo; he cried. &ldquo;He's coming
+ here!&rdquo;
+ </p>
+ <p>
+ &ldquo;Let me look!&rdquo; begged Mr. Jenks, taking the glass from Tom. An instant
+ later the diamond man exclaimed: &ldquo;Yes, it's Munson!&rdquo;
+ </p>
+ <p>
+ &ldquo;Then in here with you&mdash;quick!&rdquo; cried Renshaw. &ldquo;He can't see us yet,
+ and we'll be out of sight in another minute.&rdquo;
+ </p>
+ <p>
+ The former spirit pulled aside some thick bushes, and pointed to a hole
+ which was disclosed.
+ </p>
+ <p>
+ &ldquo;The entrance to the secret cave,&rdquo; he announced. &ldquo;Slip in all of you.&rdquo;
+ </p>
+ <p>
+ Tom, after another glance at the man toiling his way up the mountain,
+ entered the cavern. He was followed by the others. Bill was the last to
+ enter, and he replaced the bushes over the entrance.
+ </p>
+ <p>
+ &ldquo;At last!&rdquo; exclaimed Mr. Jenks, as he gazed up at the roof of the
+ dimly-lighted vault in which they found themselves.
+ </p>
+ <p>
+ &ldquo;Yes, we're in the diamond makers' secret cave,&rdquo; added Tom. &ldquo;Now to catch
+ them at work!&rdquo;
+ </p>
+ <p>
+ &ldquo;Come on,&rdquo; advised Bill, in a low tone, &ldquo;We're not safe yet,&rdquo; and he
+ produced a lantern from some hidden recess, lighted the wick, and led the
+ way. As the others followed they were aware of a subdued noise in the
+ great cavern.

+ <h2>
+ CHAPTER XX&mdash;MAKING THE DIAMONDS
+ </h2>
+ <p>
+ &ldquo;What's that noise?&rdquo; asked Tom, as their guide flashed the lantern to show
+ them the way.
+ </p>
+ <p>
+ &ldquo;That's the men getting ready to make diamonds, I guess,&rdquo; was the answer.
+ &ldquo;You see it takes quite a while to get the stuff ready. I don't know what
+ they use&mdash;they never tell me any of their secrets.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I know the ingredients well enough,&rdquo; said Mr. Jenks, &ldquo;but I don't
+ know the secret of how they apply the terrific heat and pressure necessary
+ to fuse the materials into diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, you'll soon know,&rdquo; declared Bill Renshaw. &ldquo;Of course it isn't
+ always successful. I've known 'em to try half a dozen times before they
+ got any diamonds big enough to satisfy 'em. They gave me some of the small
+ ones when I asked for my wages.
+ </p>
+ <p>
+ &ldquo;How did you come to get in with these men?&rdquo; asked Tom, curious to
+ understand how a person seemingly as honest as Renshaw appeared to be had
+ cast his lot in with the men who had broken faith with Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Oh, I've lived around these parts all my life,&rdquo; was the answer. &ldquo;I knew
+ of this cave before these diamond fellers came to it. In fact, I showed it
+ to 'em. It was several years ago that a party of men who were prospecting
+ around here came to me and asked if I knew of a small cave near the top of
+ a high mountain, where lightning storms were frequent. I told them about
+ Phantom Mountain, as it was called then, and also of this cave. If there's
+ any place where they have worse lightning storms than here, I'd like to
+ know it. They scare me, sometimes, like the night when that landslide
+ happened, and I'm sort of used to 'em.
+ </p>
+ <p>
+ &ldquo;Well, I took these men to the cave, and they hired me as a sort of
+ lookout. Then they began their work, and at first I didn't know what they
+ were up to, but finally I caught on. Then Mr. Jenks came, and disappeared
+ mysteriously, though then I didn't know that they had played a trick on
+ him. I was outside most of the time, pretending I was the ghost. So that's
+ how I came to get in with 'em, and I wish I was out.&rdquo;
+ </p>
+ <p>
+ &ldquo;You soon will be, I think,&rdquo; declared Mr. Jenks. &ldquo;But won't our talking be
+ heard by the men?&rdquo;
+ </p>
+ <p>
+ &ldquo;No danger. There is a thick wall between this part of the cave, and the
+ part where they live and work. I'll soon have you well hid, and then you
+ wait until I come back.&rdquo;
+ </p>
+ <p>
+ &ldquo;What about Munson?&rdquo; asked Tom. &ldquo;He is evidently on his way here to tell
+ his confederates about us.&rdquo;
+ </p>
+ <p>
+ &ldquo;He won't know what has happened to us,&rdquo; said Mr. Jenks, &ldquo;and he won't see
+ anything of us. I guess we're safe enough.&rdquo;
+ </p>
+ <p>
+ Through the dark passage they followed Bill Renshaw until he came to a
+ halt in a place that suddenly widened and broadened into a good-sized
+ cave.
+ </p>
+ <p>
+ &ldquo;Here's your stopping place,&rdquo; said the former ghost. &ldquo;Now if you follow
+ that passage, off to the left,&rdquo; and he pointed to it, &ldquo;you'll come to the
+ larger part of the cave where the diamond makers are. But go cautiously,
+ and don't make any noise. I won't be responsible for what happens.&rdquo;
+ </p>
+ <p>
+ &ldquo;We'll take all the risk,&rdquo; interrupted Tom.
+ </p>
+ <p>
+ &ldquo;All right. Now there's a couple of lanterns around here. I'll light them,
+ and leave you for a while until I can get some grub. I'll be back as soon
+ as I can.&rdquo;
+ </p>
+ <p>
+ He glided away, after lighting two lanterns, by the gleams of which the
+ adventurers could see that they were in a vaulted cavern that had
+ evidently been fitted up as a living apartment. The sides, roof and floor
+ were of stone. It was clean, and the air was fresh. There were some
+ chairs, a table, and several cots, with pieces of bagging for bedding,
+ though it was warm in the place.
+ </p>
+ <p>
+ &ldquo;I guess we can stay here until we discover the secret,&rdquo; spoke Tom.
+ </p>
+ <p>
+ &ldquo;Bless my watch! We can if we have something to eat,&rdquo; came from Mr. Damon,
+ with something like a sigh. &ldquo;I'm hungry!&rdquo;
+ </p>
+ <p>
+ &ldquo;And I want to make some observations,&rdquo; said Mr. Parker. &ldquo;From what I have
+ seen of this mountain, I would not be surprised if this cave was to be
+ suddenly destroyed by a landslide or a lightning bolt. I will make some
+ further investigations.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, if it's going to cause you to make such gloomy prophecies as that,
+ I'd just as soon you wouldn't look any further,&rdquo; spoke Tom, in a low
+ voice. But Mr. Parker, taking one of the lanterns, set about examining the
+ rock of which the cave consisted.
+ </p>
+ <p>
+ In a short time Bill Renshaw returned with enough food to last for two
+ days. He said he was going out on the mountain once more to act the part
+ of a lookout, and would visit the adventurers again the next day.
+ </p>
+ <p>
+ &ldquo;In the meanwhile you can do just as you please,&rdquo; he said. &ldquo;Nobody is
+ likely to disturb you here, and you can sneak up and take a look at the
+ men in the other cave whenever you're ready. Only be careful&mdash;that's
+ all I've got to say. They're desperate men.&rdquo;
+ </p>
+ <p>
+ It was not very pleasant, eating in the gloomy cavern, but they made the
+ best of it. They cooked on a small oil-stove they found in the place, and
+ after some hot coffee they felt much better.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked Tom, after a while, &ldquo;shall we take a chance, and go look
+ at the men at work?&rdquo;
+ </p>
+ <p>
+ &ldquo;I think so,&rdquo; answered Mr. Jenks. &ldquo;The sooner we discover this mystery,
+ the better. Then we can go back home.&rdquo;
+ </p>
+ <p>
+ &ldquo;And recover my airship,&rdquo; added Tom, who was a bit uneasy regarding the
+ safety of the Red Cloud.
+ </p>
+ <p>
+ &ldquo;Then, bless my finger-rings! let's go and see if we can find the big cave
+ your friend the ghost told us of,&rdquo; suggested Mr. Damon.
+ </p>
+ <p>
+ Cautiously they made their way along the passage Bill had pointed out. As
+ they went forward the subdued noise became louder, and finally they could
+ feel the vibration of machinery.
+ </p>
+ <p>
+ &ldquo;This is the place,&rdquo; whispered Mr. Jenks. &ldquo;That sound we hear is one of
+ the mixing machines, for grinding the materials&mdash;carbon and the other
+ substances&mdash;which go to make up the diamonds. I remember hearing that
+ when I was in the cave before.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we must be near the place,&rdquo; observed Tom.
+ </p>
+ <p>
+ &ldquo;Yes, but I didn't have much chance to look around when I was here before.
+ They wouldn't let me. I never even knew of the small cave Bill took us
+ to.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, if we're close to it, we'd better go cautiously, and not talk any
+ more than we're obliged to,&rdquo; suggested Mr. Parker, and they agreed that
+ this was good advice.
+ </p>
+ <p>
+ They walked on softly. Suddenly Tom, who was in the lead, saw a gleam of
+ light.
+ </p>
+ <p>
+ &ldquo;We're here,&rdquo; he whispered. &ldquo;I'll put out our lantern, now,&rdquo; which he did.
+ Then, stealing forward he and the others beheld a curious sight. The
+ tunnel they were in ended at a small hole which opened into a large
+ cavern, and, fortunately, this opening was concealed from the view of
+ those in the main place.
+ </p>
+ <p>
+ &ldquo;The diamond makers!&rdquo; whispered Tom, hoarsely, pointing to several men
+ grouped about a number of strange machines.
+ </p>
+ <p>
+ &ldquo;Yes&mdash;the very place where I was,&rdquo; answered Mr. Jenks, &ldquo;and there is
+ the apparatus&mdash;the steel box&mdash;from which the diamonds are taken&mdash;now
+ to see how they make them.&rdquo;
+ </p>
+ <p>
+ Fascinated, the adventurers looked into the cave. The men there were
+ unaware of the presence of our friends, and were busily engaged. Some
+ attended to the grinding machine, the roar and clatter of which made it
+ possible for Tom and the others to talk and move about without being
+ overheard. Into this machine certain ingredients were put, and they were
+ then pulverized, and taken out in powdery form.
+ </p>
+ <p>
+ The power to run the mixing machine was a gasoline motor, which
+ chug-chugged away in one corner of the cave.
+ </p>
+ <p>
+ As the powder was taken out, other men fashioned it into small balls,
+ which were put on pan, and into a sort of oven, that was heated by a
+ gasoline stove.
+ </p>
+ <p>
+ &ldquo;Is that how they make the diamonds?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ &ldquo;That is evidently the first step,&rdquo; said Mr. Jenks. &ldquo;Those balls of
+ powdered chemicals are partly baked, and then they are put into the steel
+ box. In some way terrific heat and pressure are applied, and the diamonds
+ are made. But how the heat and pressure are obtained is what we have yet
+ to learn.&rdquo;
+ </p>
+ <p>
+ He paused to watch the men at work. They were all busy, some attending to
+ the machines, and others coming and going in and out of the cave. In one
+ part a man was apparently getting ready a meal.
+ </p>
+ <p>
+ Suddenly there rushed into the cave a man who seemed much excited.
+ </p>
+ <p>
+ &ldquo;Are you nearly ready with that stuff?&rdquo; he cried. &ldquo;There's a good storm
+ gathering on the mountain!&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, we'll be ready in half an hour,&rdquo; answered one of the men at the
+ mixing machine.
+ </p>
+ <p>
+ &ldquo;Good. It will be flashing lightning bolts then, and we can see what luck
+ we have. The last batch was a failure.&rdquo; The man hurried out again. Mr.
+ Parker touched Tom and Mr. Jenks on their shoulders.
+ </p>
+ <p>
+ &ldquo;What is it?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;I know the secret of making the diamonds,&rdquo; said the scientist.
+ </p>
+ <p>
+ &ldquo;What?&rdquo; cried Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;It is by the awful power of the lightning bolts!&rdquo; whispered Mr. Parker.
+ &ldquo;Everything is explained now&mdash;the reason why they make diamonds in
+ this lonely place, near the top of the mountain. They need a place where
+ the lightning is powerful. I can understand it now&mdash;I suspected it
+ before. They make diamonds by lightning!&rdquo;
+ </p>
+ <p>
+ &ldquo;Are you sure?&rdquo; cried Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Positive.&rdquo;
+ </p>
+ <p>
+ &ldquo;I agree with you,&rdquo; said Tom Swift. &ldquo;I was just getting on that track
+ myself, when I saw the electric wires running to the steel box. That
+ explains the upright rod on the top of the mountain. The man says a storm
+ is coming&mdash;very well; we'll stay here and watch them make diamonds!&rdquo;
+ </p>
+ <p>
+ As he spoke there came the mutter of thunder, and the mountain vibrated
+ slightly. The men in the cave redoubled their activity. Tom and his
+ friends felt that the secret process they had so long sought was about to
+ be demonstrated before their eyes.

+ <h2>
+ CHAPTER XXI&mdash;FLASHING GEMS
+ </h2>
+ <p>
+ Eagerly the adventurers looked through the opening at the end of the
+ passage into the larger cave. The men opened the small oven in which the
+ balls of white chemicals and carbon mixed, had been baked, and a pile of
+ things, that looked like irregularly-shaped marbles, were placed in the
+ steel box.
+ </p>
+ <p>
+ This box, which was about the size of a trunk, was of massive metal. It
+ was placed in a recess in the solid rock, and all about were layers of
+ asbestos and other substances that were nonconductors of heat.
+ </p>
+ <p>
+ &ldquo;That box becomes red hot,&rdquo; exclaimed Mr. Jenks, in a whisper. &ldquo;When
+ things are in readiness, that lever is pulled and the diamonds are made. I
+ pulled it once, but I did not then know the process involved. I supposed
+ that the lightning had nothing to do with making the diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;It has&mdash;a most important part,&rdquo; said Mr. Parker. The hidden
+ adventurers could talk in perfect safety now, for the men in the large
+ cave were too excited to pay much attention to them. The muttering of the
+ thunder grew louder, and at times a particularly loud crash told that a
+ bolt had struck somewhere in the vicinity of the cave.
+ </p>
+ <p>
+ &ldquo;But, bless my watch-charm!&rdquo; exclaimed Mr. Damon, &ldquo;I didn't know lightning
+ made diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;It does not&mdash;always,&rdquo; went on the scientist. &ldquo;But great heat and
+ pressure are necessary to create the gems. In nature this was probably
+ obtained by prehistoric volcanic fires, and by the terrific pressure of
+ immense rocks. It is possible to make diamonds in the laboratory of the
+ chemist, but they are so minute as to be practically valueless.
+ </p>
+ <p>
+ &ldquo;However, these men seem to have hit upon a new plan. They utilize the
+ terrific heat of lightning, and the pressure which is instantaneously
+ obtained when the bolt strikes. I am anxious to see how it is done. Look,
+ I think they are getting ready to make the gems.&rdquo;
+ </p>
+ <p>
+ Indeed there seemed to be an air of expectancy among the diamond makers.
+ The mixing machine had now been stopped, and, as it was more quiet in the
+ cave, our friends, in their hiding-place, had to speak in mere whispers.
+ All the men were now gathered about the great steel box.
+ </p>
+ <p>
+ This receptacle had been closed by a solid metal door, which was screwed
+ and clamped tight. Then one of the men examined a number of heavily
+ insulated electric wires that extended from the box off into the darkness
+ where Tom and his companions could not discern them.
+ </p>
+ <p>
+ &ldquo;That's Folwell&mdash;the man I befriended, and who got me into this
+ game,&rdquo; whispered Mr. Jenks. &ldquo;He was also one of the first to turn against
+ me. I think he's one of the leaders.&rdquo;
+ </p>
+ <p>
+ Folwell came back, after having gone into a dark part of the cave. He went
+ over to an electrical switch on one of the stone walls.
+ </p>
+ <p>
+ &ldquo;It's almost time,&rdquo; Tom heard him say to his confederates. &ldquo;The storm is
+ coming up rapidly.&rdquo;
+ </p>
+ <p>
+ &ldquo;Will it be severe enough?&rdquo; asked one of the helpers. &ldquo;We had all our work
+ for nothing last time. The flashes weren't heavy enough.&rdquo;
+ </p>
+ <p>
+ &ldquo;These will be,&rdquo; asserted Folwell. &ldquo;The indicator shows nearly a million
+ volts now, and it's increasing.&rdquo;
+ </p>
+ <p>
+ &ldquo;A million volts!&rdquo; exclaimed Tom. &ldquo;I hope it doesn't strike anywhere
+ around here.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, it will probably be harmlessly conducted down on the heavy wires,&rdquo;
+ said Mr. Parker. &ldquo;We are in no danger, at present, though ultimately I
+ expect to see the whole mountain shattered by a lightning bolt.&rdquo;
+ </p>
+ <p>
+ &ldquo;Cheerful prospect,&rdquo; murmured Tom.
+ </p>
+ <p>
+ There was a terrific crash outside. The rocky floor of the cave trembled.
+ </p>
+ <p>
+ &ldquo;Here she comes!&rdquo; cried Folwell. &ldquo;Get back, everybody! I'm going to throw
+ over the switch now!&rdquo;
+ </p>
+ <p>
+ The men retreated well away from the steel box. Folwell threw over the
+ lever&mdash;the same one Mr. Jenks remembered pulling. Then the man ran to
+ the electric switch on the wall, and snapped that into place, establishing
+ a connection.
+ </p>
+ <p>
+ There was a moment's pause, as Folwell ran to join the others in their
+ place of safety. Then from without there came a most nerve-racking and
+ terrifying crash. It seemed as if the very mountain would be rent into
+ fragments.
+ </p>
+ <p>
+ Watching with eager eyes, the adventurers saw sparks flash from the steel
+ box. Instantly it became red hot, and then glowed white and incandescent.
+ It was almost at the melting point.
+ </p>
+ <p>
+ Then came comparative quiet, as the echoes of the thunder died away amid
+ the mountain peaks.
+ </p>
+ <p>
+ &ldquo;I guess that did the trick!&rdquo; cried Folwell. &ldquo;It was a terrific crash all
+ right!&rdquo;
+ </p>
+ <p>
+ He and the others ran forward. The steel box was now a cherry red, for it
+ was cooling. Folwell threw back the lever, and another man disconnected
+ the switch. There was a period of waiting until the box was cool enough to
+ open. Then the heavy door was swung back.
+ </p>
+ <p>
+ With a long iron rod Folwell drew something from the retort. It was the
+ tray which had held the white balls. But they were white no longer, for
+ they had been turned into diamonds. From their hiding-place Tom and the
+ others could see the flashing gems, for, in spite of the fact that the
+ diamonds were uncut, some of them sparkled most brilliantly, due to the
+ peculiar manner in which they were made.
+ </p>
+ <p>
+ &ldquo;We have the secret of the diamonds!&rdquo; whispered Mr. Jenks. &ldquo;There must be
+ a quart of the gems there!&rdquo;
+ </p>
+ <p>
+ The men gathered about Folwell, uttering exclamations of delight. The
+ diamonds were too hot to handle yet.
+ </p>
+ <p>
+ &ldquo;That's going some!&rdquo; exclaimed the chief of the diamond makers. &ldquo;We have a
+ small fortune here.&rdquo;
+ </p>
+ <p>
+ The was a sudden commotion at one end of the cave. A man rushed in. At the
+ sight of him Tom stared and uttered an exclamation.
+ </p>
+ <p>
+ &ldquo;Munson&mdash;the stowaway!&rdquo; he whispered.
+ </p>
+ <p>
+ &ldquo;Hello!&rdquo; cried Folwell, as he saw his confederate. &ldquo;I thought you were
+ East, keeping Jenks away from here.&rdquo;
+ </p>
+ <p>
+ &ldquo;He got the best of me!&rdquo; cried Munson, &ldquo;he and that Tom Swift! I stowed
+ away on their airship, but they found me out by a wireless message, and
+ marooned me in the woods. I've been trying to get here ever since! Didn't
+ you get my messages of warning?&rdquo;
+ </p>
+ <p>
+ &ldquo;No&mdash;what warnings?&rdquo; cried Folwell.
+ </p>
+ <p>
+ &ldquo;About Jenks, Tom Swift and the others. They're here&mdash;they must be on
+ Phantom Mountain now. In fact, I shouldn't be surprised if they were in
+ this cave. I traced them to their camp, but they're gone. They may be
+ among us now&mdash;in some of the secret recesses!&rdquo;
+ </p>
+ <p>
+ For an instant Folwell stared at the bearer of these tidings. Then he
+ cried out:
+ </p>
+ <p>
+ &ldquo;Scatter men, and find these fellows! We must get them before they
+ discover our secret!&rdquo;
+ </p>
+ <p>
+ &ldquo;It's too late&mdash;we know it!&rdquo; exulted Tom Swift. Then he whispered to
+ the others to hurry to the part of the cave where Bill Renshaw had first
+ hidden them.

+ <h2>
+ CHAPTER XXII&mdash;PRISONERS
+ </h2>
+ <p>
+ &ldquo;Do you think there is any danger of them finding us?&rdquo; asked Mr. Damon, as
+ he hurried along beside Tom.
+ </p>
+ <p>
+ &ldquo;I'm afraid so,&rdquo; was the answer. &ldquo;I've been worried ever since we saw
+ Munson heading this way. But we couldn't do any differently.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps Bill Renshaw may be able to conceal us,&rdquo; suggested Mr. Jenks.
+ &ldquo;Very likely he knows that Munson is on hand. Perhaps we will be safe for
+ a while. I want to make a few more observations as to how they manufacture
+ the diamonds, and then, with what I already know, I'll have the secret.&rdquo;
+ </p>
+ <p>
+ &ldquo;And I'd like to make some scientific tests of the sides and bottom rocks
+ of the cave,&rdquo; spoke Mr. Parker. &ldquo;I think it will bear out my theory that
+ the mountain will soon be destroyed.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, you were right about Earthquake Island, and you may be right about
+ this mountain,&rdquo; said Tom, &ldquo;but if it is going to be annihilated I hope we
+ get far enough away from it.&rdquo;
+ </p>
+ <p>
+ &ldquo;We can keep our presence here a secret for a few more days, I think that
+ will be long enough,&rdquo; proceeded Mr. Jenks. &ldquo;Then we will leave.&rdquo;
+ </p>
+ <p>
+ &ldquo;And, in the meanwhile, they'll be searching for us,&rdquo; objected Mr. Damon.
+ &ldquo;I wish that ghost-chap would come back and tell us what to do. Bless my
+ liver-pin, but we are going to be in considerable danger, I'm afraid!
+ Those men may capture us, and decide to make diamond dust from us.&rdquo;
+ </p>
+ <p>
+ &ldquo;Come on&mdash;hurry to the little cave,&rdquo; urged Tom. &ldquo;Then we'll get ready
+ to defend ourselves.&rdquo;
+ </p>
+ <p>
+ &ldquo;The main cave is a large one,&rdquo; said Mr. Jenks, &ldquo;and there are many hiding
+ places in it. In fact, it is so large that it will take those fellows
+ several days to complete a circuit of it. By that time Bill Renshaw may
+ come back, and take us to some place in which they have already searched
+ for us. Then we'll be comparatively safe.&rdquo;
+ </p>
+ <p>
+ This thought was some consolation to them, as they made their way through
+ the dark passage, dimly illuminated by the lantern they had rekindled, to
+ the place where Bill had hidden them. They found things as they had left
+ them, and proceeded to get a meal, though Tom said it would be best not to
+ cook anything, or even to make coffee, for fear the odors would enable the
+ searchers to trail them.
+ </p>
+ <p>
+ So they ate cold food, glad to get that. Silently they sat about the
+ dimly-lighted cavern, and discussed the situation. True they might even
+ now retreat, going out of the entrance Bill had showed them, and so
+ escape. But Mr. Jenks felt that his mission was not completed yet, and
+ they all agreed to stay with him.
+ </p>
+ <p>
+ &ldquo;For there are several points about making diamonds that are not quite
+ clear to me,&rdquo; he said. &ldquo;I need to know how that steel box is constructed,
+ how the electrical switches are arranged, what kind of lightning rods they
+ use, and how they regulate the pressure. The other things, and how to mix
+ the ingredients, I already know.&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'll do our best to help you,&rdquo; promised Tom. &ldquo;But now I think we
+ had better see what sort of a defense we can put up. We have our guns and
+ revolvers, and with these chairs and tables we can build a sort of
+ barricade behind which we can take refuge if those fellows do discover our
+ hiding place.&rdquo;
+ </p>
+ <p>
+ This was conceded to be a good idea, and soon a rude sort of fort was
+ made, behind which the adventurers could take their stand and fight, if
+ necessary, though they hoped this would not come to pass.
+ </p>
+ <p>
+ They remained quietly in the cave the remainder of that day, and, when it
+ was night, as they could tell by their timepieces&mdash;there was no
+ daylight&mdash;they divided the hours into watches, taking turns standing
+ guard.
+ </p>
+ <p>
+ Morning, at least in point of time, came without any disturbance, and they
+ made a cold breakfast. They hoped that Bill Renshaw would come, but he did
+ not appear.
+ </p>
+ <p>
+ After sitting in the dark cave until afternoon, Tom said:
+ </p>
+ <p>
+ &ldquo;I think we might as well go and take another observation of the big cave.
+ We can tell what the men are doing, then, for they don't seem to have been
+ near us. Maybe they have given up the search for us, and we can see them
+ at work, and Mr. Jenks can gain what further knowledge he needs.&rdquo;
+ </p>
+ <p>
+ &ldquo;That will be a good plan,&rdquo; agreed the diamond man. &ldquo;It's maddening to sit
+ here, doing nothing.&rdquo;
+ </p>
+ <p>
+ &ldquo;And it will be comparatively safe to go from here to our former post of
+ observation,&rdquo; added Tom, &ldquo;for there doesn't seem to be any opening along
+ the tunnel, into the larger cave, except the place where we were.&rdquo;
+ </p>
+ <p>
+ Accordingly they started off. Cautiously they looked through the opening
+ into the apartment where they had seen the diamonds made.
+ </p>
+ <p>
+ &ldquo;There's not a soul here!&rdquo; exclaimed Tom, in a whisper. The others looked.
+ The place was deserted&mdash;the machinery silent. Mr. Jenks peered in for
+ a moment, and then exclaimed:
+ </p>
+ <p>
+ &ldquo;I'm going in! Now's my chance to find out all that I wish to know! It may
+ never come again, and then we can soon leave Phantom Mountain!&rdquo;
+ </p>
+ <p>
+ It was a daring plan, but it seemed to be the best one to follow. They
+ were all tired of inactivity. Mr. Jenks managed to get through the
+ opening, and dropped into the big cave. The others followed. Mr. Jenks
+ hurried over to the steel box, and began an examination of it. Tom Swift
+ was looking at the electrical switch. He saw how it was constructed. Mr.
+ Damon and Mr. Parker were peering interestedly about.
+ </p>
+ <p>
+ Suddenly the sound of voices was heard, and the echo of footsteps. Mr.
+ Jenks started.
+ </p>
+ <p>
+ &ldquo;They're coming back!&rdquo; he whispered hoarsely. &ldquo;Run!&rdquo;
+ </p>
+ <p>
+ They all turned and sped toward their hiding place. But they were too
+ late. An instant later Folwell, Munson and the other diamond makers
+ confronted them. Our friends made a bold rush, but were caught before they
+ could go ten feet.
+ </p>
+ <p>
+ &ldquo;We have them!&rdquo; cried Munson. &ldquo;They walked right into our hands!&rdquo;
+ </p>
+ <p>
+ It was true. Tom Swift and the others were the prisoners of the diamond
+ makers.

+ <h2>
+ CHAPTER XXIII&mdash;BROKEN BONDS
+ </h2>
+ <p>
+ &ldquo;Well,&rdquo; remarked Tom Swift, in mournful tones, &ldquo;this looks as if we were
+ up against it; doesn't it?&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my umbrella, it certainly does,&rdquo; agreed Mr. Damon.
+ </p>
+ <p>
+ &ldquo;And it's all my fault,&rdquo; said Mr. Jenks. &ldquo;I shouldn't have gone into the
+ big cave. I might have known those men would come back any time.&rdquo;
+ </p>
+ <p>
+ The above conversation took place as our friends lay securely bound in a
+ small cave, or recess, opening from the larger cavern, where, about an
+ hour before, they had been captured and made prisoners by the diamond
+ makers. Despite their struggles they had been overpowered and bound, being
+ carried to the cave, where they were laid in a row on some old bags.
+ </p>
+ <p>
+ &ldquo;It certainly is a most unpleasant situation, to say the least,&rdquo; observed
+ Mr. Parker.
+ </p>
+ <p>
+ &ldquo;And all my fault,&rdquo; repeated Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;Oh, no it isn't,&rdquo; declared Tom Swift, quickly. &ldquo;We were just as ready to
+ follow you into that cave as you were to go. No one could tell that the
+ men would return so soon. It's nobody's fault. It's just our bad luck.&rdquo;
+ </p>
+ <p>
+ From where he lay, tied hand and foot, the young inventor could look out
+ into the cave where he and the others had been caught. The diamond makers
+ were busily engaged, apparently in getting ready to manufacture another
+ batch of the precious stones. They paid little attention to their
+ captives, save to warn them, when they had first been taken into the
+ little cave, that it was useless to try to escape.
+ </p>
+ <p>
+ &ldquo;They needn't have told us that,&rdquo; observed Tom, as he and the others were
+ talking over their situation in low voices. &ldquo;I don't believe any one could
+ loosen these ropes.&rdquo;
+ </p>
+ <p>
+ &ldquo;They certainly are pretty tight,&rdquo; agreed Mr. Damon. &ldquo;I've been tugging
+ and straining at mine for the last half hour, and all I've succeeded in
+ doing is to make the cords cut into my flesh.&rdquo;
+ </p>
+ <p>
+ &ldquo;Better give it up,&rdquo; advised Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;We'll just have to wait.&rdquo;
+ </p>
+ <p>
+ &ldquo;For what?&rdquo; the scientist wanted to know.
+ </p>
+ <p>
+ &ldquo;To see what they'll do with us. They can't keep us here forever. They'll
+ have to let us go some time.&rdquo; Following their capture, Folwell and Munson,
+ the latter the stowaway of the airship, had been in earnest conversation
+ regarding our friends, but what conclusion they had reached the
+ adventurers could only guess.
+ </p>
+ <p>
+ &ldquo;And we didn't have time to examine the diamond-making machinery close
+ enough so that we could duplicate it if necessary,&rdquo; complained Tom, a
+ little later.
+ </p>
+ <p>
+ &ldquo;No,&rdquo; agreed Mr. Jenks. &ldquo;There are certain things about it that are not
+ clear to me. Well, I don't believe I'll have another chance to inspect it.
+ They'll take good care of that, though they seem to be getting ready to
+ make more diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;Perhaps they're going to manufacture a big batch, and then leave this
+ place,&rdquo; suggested Mr. Damon. &ldquo;They will probably go to some other secret
+ cave, and leave us here.&rdquo;
+ </p>
+ <p>
+ &ldquo;I hope they untie us before they leave, and give us something to eat,&rdquo;
+ remarked the young inventor.
+ </p>
+ <p>
+ For two hours longer the captives lay there, in most uncomfortable
+ positions. Then Folwell and Munson, leaving the group of diamond makers
+ who were grouped about the machinery, approached the captives.
+ </p>
+ <p>
+ &ldquo;Well,&rdquo; remarked Munson, &ldquo;we got ahead of you after all; didn't we. You
+ thought you had our secret, but it will be a long while before you ever
+ make diamonds.&rdquo;
+ </p>
+ <p>
+ &ldquo;What are you going to do with us?&rdquo; asked Tom.
+ </p>
+ <p>
+ &ldquo;Never mind. You came where you had no right to, and you must take the
+ consequences.&rdquo;
+ </p>
+ <p>
+ &ldquo;We did have a right to come here!&rdquo; exclaimed Mr. Jenks. &ldquo;I am entitled to
+ know how the diamonds are made. I paid for the information, and you
+ tricked me. If ever it's possible I'll have the whole gang arrested for
+ swindling.&rdquo;
+ </p>
+ <p>
+ &ldquo;You'll never get the chance!&rdquo; declared Folwell. &ldquo;You were given some
+ diamonds for the money you invested, and that makes us square.&rdquo;
+ </p>
+ <p>
+ &ldquo;No, it doesn't!&rdquo; declared Mr. Jenks. &ldquo;I invested the money to learn how
+ to make diamonds, and you know it! You tricked me, and I had a right to
+ try to discover your secret! I nearly have it, too, and I'll get it
+ completely before I'm done with you!&rdquo;
+ </p>
+ <p>
+ &ldquo;No, you won't!&rdquo; boasted Folwell. &ldquo;But we didn't come here to tell you
+ that. We came to give you something to eat. We're not savages and we'll
+ treat you as well as we can in spite of the fact that you are trespassers.
+ We're going to give you some grub, but I warn you that any attempt to
+ escape will mean that some of you will get hurt.&rdquo;
+ </p>
+ <p>
+ He signalled to some of his confederates. These men unbound the captives'
+ arms, and stood over them while they ate some coarse food that was brought
+ into the small cave. They were given coffee to drink, and then, when the
+ simple meal was over, they were securely bound again, and left to
+ themselves, while the diamond makers went back to their machinery.
+ </p>
+ <p>
+ It was evident that they were going to attempt a big operation, for an
+ unusually large quantity of the white stuff was prepared. The prisoners
+ watched them idly. They could see some but not all of the operations. In
+ this way several hours passed.
+ </p>
+ <p>
+ Gloom possessed the hearts of Tom and his friends. Not only had their
+ expedition been almost a failure so far, but the young inventor was
+ worried lest the gang might discover and wreck his airship. This would
+ prove a serious loss. Lying there in the semi-darkness the lad imagined
+ all sorts of unpleasant happenings.
+ </p>
+ <p>
+ At times he dozed off, as did the others. They had become somewhat used to
+ the pain caused by the bonds, for their nerves were numb from the strain
+ and pressure.
+ </p>
+ <p>
+ Once, as he was lightly sleeping, Tom was awakened by hearing loud voices
+ in the main cave. He looked out, rolling over slightly to get a better
+ view. He saw the man who, once before had run in to give news of an
+ approaching electrical storm.
+ </p>
+ <p>
+ &ldquo;Are you fellows all ready?&rdquo; asked this same man again.
+ </p>
+ <p>
+ &ldquo;Yes. Is there another storm coming?&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, and it's going to be a corker!&rdquo; was the reply. &ldquo;It's one of the
+ worst I've ever seen. It's sweeping right up the valley. It'll be here in
+ an hour.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's good. We need a big flash to make all the material we have
+ prepared into diamonds. It's the biggest batch we ever tried. I hope it
+ succeeds, for we're going to leave&mdash;&rdquo; The rest was in so low a tone
+ that Tom could not catch it.
+ </p>
+ <p>
+ The storm messenger departed. Folwell and Munson busied themselves about
+ the machinery. Tom dozed off again, dimly wondering what had become of
+ Bill Renshaw, and whether the former ghost knew of their plight. The
+ others were asleep, as the young inventor saw by the dim light of a
+ lantern in the cave. Then, he too, shut his eyes.
+ </p>
+ <p>
+ Tom was suddenly awakened by feeling some one's hands moving about his
+ clothing. At first he thought it was one of the diamond-making gang, who
+ had sneaked in to rob him. &ldquo;Here! What are you up to?&rdquo; exclaimed Tom.
+ </p>
+ <p>
+ &ldquo;Quiet!&rdquo; cautioned a voice. &ldquo;Are you all here?&rdquo;
+ </p>
+ <p>
+ &ldquo;All of us&mdash;yes. But who are you?&rdquo;
+ </p>
+ <p>
+ &ldquo;Easy&mdash;keep quiet, Tom Swift! I'm Bill Renshaw! I've been searching
+ all over for you, since I got back to your cave and found it empty. Now
+ I'm going to free you. I got in here by a secret entrance. Wait, I'll cut
+ your ropes.&rdquo; There was a slight sound, and an instant later Tom was freed
+ from his bonds.

+ <h2>
+ CHAPTER XXIV&mdash;IN GREAT PERIL
+ </h2>
+ <p>
+ The young inventor could scarcely believe the good luck that had so
+ unexpectedly come to him and his companions. No sooner was Tom able to
+ move freely about than Bill Renshaw performed the same service for Mr.
+ Jenks and the others, cautioning them to be quiet as he awakened them, and
+ cut the ropes.
+ </p>
+ <p>
+ &ldquo;Bless my circulation!&rdquo; exclaimed Mr. Damon, in a hoarse whisper. &ldquo;How did
+ you ever get here. I'd given ourselves up for lost.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I came in off the mountain, as there's a big storm due,&rdquo; explained
+ the man. &ldquo;There was no need of me playing the haunt in daytime, anyhow. I
+ went to the cave, found you and your things gone, and I surmised that you
+ might have walked into some trap.&rdquo;
+ </p>
+ <p>
+ &ldquo;We did,&rdquo; admitted Mr. Jenks, grimly.
+ </p>
+ <p>
+ &ldquo;Well, I hunted around until I found you,&rdquo; went on Bill. &ldquo;This mountain is
+ honeycombed with caves, all opening from the large one, I know them better
+ than these fellows do, so I could explore freely, and keep out of their
+ sight. They didn't know that there was a second entrance to this place,
+ but I did, and I made for it, when I couldn't find you in some of the
+ other caves where I looked. And, sure enough, here you were.&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, we can't thank you enough,&rdquo; said Mr. Parker. &ldquo;But you say there is
+ a big storm coming?&rdquo;
+ </p>
+ <p>
+ &ldquo;One of the biggest that's been around these parts in some time,&rdquo; replied
+ Bill.
+ </p>
+ <p>
+ &ldquo;Then perhaps the mountain will be destroyed,&rdquo; went on the scientist, as
+ calmly as if he had remarked that it might rain.
+ </p>
+ <p>
+ &ldquo;I hope nothing like that happens until we get away,&rdquo; spoke Mr. Damon,
+ fervently.
+ </p>
+ <p>
+ &ldquo;What had we better do?&rdquo; inquired Tom.
+ </p>
+ <p>
+ &ldquo;Get away, unless you want to discover some more of their secrets,&rdquo;
+ advised Bill. &ldquo;Those fellows are planning something, but I can't find out
+ what it is. They are suspicious of me, I think. But they are up to
+ something, and I believe, it would be best for you to leave while you have
+ the chance. It may not be healthy to stay. That's why I did my best to
+ untie you.&rdquo;
+ </p>
+ <p>
+ &ldquo;We appreciate what you have done,&rdquo; declared Mr. Jenks, &ldquo;but I want my
+ rights. I must learn a few more facts about how to make diamonds from
+ lightning flashes, and then I will have the same secret they cheated me
+ out of. I think if we wait a while we may be able to see the parts of the
+ process that are not quite clear to us. What do you say, Tom Swift?&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, I would like to learn the secret,&rdquo; replied the lad, &ldquo;and if Bill
+ thinks it's safe to stay here a while longer&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, I guess it will be safe enough,&rdquo; was the reply. &ldquo;Those fellows won't
+ bother about you now that they are about to make some more diamonds.
+ Besides, they think you're all tied up. Yes, you can stay here and watch,
+ I reckon. I've got a couple of guns, and&mdash;&rdquo;
+ </p>
+ <p>
+ &ldquo;Then we'll stay,&rdquo; decided Tom. &ldquo;We can put up a better fight now.&rdquo;
+ </p>
+ <p>
+ Silently, in their prison, but which they could now leave whenever they
+ pleased, the adventurers watched the diamond makers once more. The same
+ process they had witnessed before was gone through with. The white balls
+ were put inside the steel box and sealed up. Then they waited for the
+ storm to reach its height.
+ </p>
+ <p>
+ That this would not be long was evidenced by the mutterings of thunder
+ which every moment grew louder. The outburst of electrical fury was likely
+ to take place momentarily, and that it would be unusually severe was shown
+ by the precautions taken by the diamond makers. They attached a number of
+ extra wires, and brought out some insulated, hard rubber platforms, on
+ which they themselves stood. Tom and Mr. Jenks were much interested in
+ watching this detail of the work, and sought to learn how each part of the
+ process was done.
+ </p>
+ <p>
+ &ldquo;I almost think we can make diamonds, Tom, when we get back to
+ civilization,&rdquo; whispered Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I hope we can,&rdquo; answered Tom, &ldquo;and we can't get back any too soon to suit
+ me. I want to be in my airship again.&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't blame you. But look, they are getting ready to adjust the
+ switch.&rdquo;
+ </p>
+ <p>
+ The adventurers ceased their whispered talk, and eagerly watched the
+ diamond makers. Folwell and Munson were hurrying to and fro in the big
+ cave, attending to the adjustments of the machinery.
+ </p>
+ <p>
+ &ldquo;On your insulated plates&mdash;all of you,&rdquo; Folwell gave the order. &ldquo;This
+ is going to be a terrific storm. The gage shows twice the power we have
+ ever used, and it's creeping up every minute! We'll have more diamonds
+ than ever had before!&rdquo;
+ </p>
+ <p>
+ &ldquo;Yes, if the mountain isn't destroyed,&rdquo; added Mr. Parker, in a low voice.
+ &ldquo;I predict that it will be split from top to bottom!&rdquo;
+ </p>
+ <p>
+ &ldquo;Comforting,&rdquo; thought Tom, grimly.
+ </p>
+ <p>
+ &ldquo;I guess we're all ready,&rdquo; said Folwell, in a low tone to Munson. &ldquo;We'd
+ better get insulated ourselves. I'm going to throw the switch.&rdquo;
+ </p>
+ <p>
+ He did so. A moment later the man who had before given warning of the
+ storm came dashing in. He was very much excited.
+ </p>
+ <p>
+ &ldquo;It's awful!&rdquo; he cried. &ldquo;The lightning is striking all over! Big rocks are
+ being split like logs of wood!&rdquo;
+ </p>
+ <p>
+ &ldquo;Well, it can't do any damage in here,&rdquo; said Munson. &ldquo;We are well
+ protected. Get on one of the plates,&rdquo; and he motioned to one of the
+ hard-rubber platforms that was not occupied. The roar and rumble of the
+ storm outside had given place to short terrific crashes. In their small
+ cave the adventurers could feel the solid ground shake.
+ </p>
+ <p>
+ A bluish light began dancing about the electrical wires. There was a smell
+ of sulphur in the air. Crash after crash resounded outside. A flash of
+ flame lit up the whole interior of the cave. It came from the copper
+ switch.
+ </p>
+ <p>
+ &ldquo;Something's wrong with the insulation!&rdquo; cried Munson.
+ </p>
+ <p>
+ &ldquo;Don't go near it!&rdquo; yelled Folwell. &ldquo;If you value your life, stand still!&rdquo;
+ </p>
+ <p>
+ Hardly had he spoken than inside the cavern there sounded a report like
+ that of a small cannon. A big ball of fire danced about the middle of the
+ cave and then leaped on top of the steel box.
+ </p>
+ <p>
+ &ldquo;This is a fearful storm,&rdquo; cried Munson.
+ </p>
+ <p>
+ The adventurers in the cave did not know what to say or do. They were in
+ deadly peril.
+ </p>
+ <p>
+ Suddenly there came a crash louder than any that had preceded it. The
+ whole side of the cave where the switches were was a mass of bluish flame.
+ Then came a ripping, tearing sound, and a tangle of wires and copper
+ connections were thrown to the floor. At the same time the steel box,
+ containing the materials from which diamonds were made, turned blue, and
+ flames shot from it.
+ </p>
+ <p>
+ &ldquo;It's all up with us!&rdquo; cried Munson. &ldquo;Run for it, everybody! The wires are
+ down, and this place will be an electric furnace in another minute!&rdquo;
+ </p>
+ <p>
+ He leaped toward the exit from the cave.
+ </p>
+ <p>
+ &ldquo;What about those fellows?&rdquo; asked Folwell, indicating the place where Tom
+ and the others had been tied.
+ </p>
+ <p>
+ &ldquo;They'll have to do the best they can! It's every man for himself, now!&rdquo;
+ yelled Munson. There was a wild scramble from the cavern.
+ </p>
+ <p>
+ &ldquo;Come on!&rdquo; cried Tom. &ldquo;We must escape! It's our only chance!&rdquo;
+ </p>
+ <p>
+ He leaped into the big cave, followed by the others. Already long tongues
+ of electrical fire were shooting out from the walls and roof as Tom Swift
+ and his companions, evading them as best they could, sought safety in
+ flight.

+ <h2>
+ CHAPTER XXV&mdash;THE MOUNTAIN SHATTERED&mdash;CONCLUSION
+ </h2>
+ <p>
+ &ldquo;Can't we get some of the diamonds?&rdquo; cried Mr. Damon, as he raced along
+ behind Tom. &ldquo;Now's our chance. Those fellows have all gone!&rdquo; The odd man
+ made a grab for something as he ran.
+ </p>
+ <p>
+ &ldquo;It's as much as our lives are worth,&rdquo; declared the young inventor. &ldquo;We
+ dare not stop! Come on!&rdquo;
+ </p>
+ <p>
+ &ldquo;I'd like to investigate some of the machinery,&rdquo; spoke Mr. Jenks, &ldquo;but I
+ wouldn't stop, even for that.&rdquo;
+ </p>
+ <p>
+ &ldquo;The storm is too dangerous,&rdquo; called Bill Renshaw. &ldquo;I can show you a
+ shorter way out than the one those fellows have taken. Follow me.&rdquo;
+ </p>
+ <p>
+ &ldquo;No way can be too short,&rdquo; said Mr. Parker, solemnly. &ldquo;This mountain will
+ go to pieces shortly, I think!&rdquo;
+ </p>
+ <p>
+ Tom shuddered. He remembered how narrow had been their escape when
+ Earthquake Island sank into the sea. And that some terrific upheaval was
+ now imminent might be judged from the awful reports that sounded more
+ plainly as the adventurers raced toward the opening of the cave. It was
+ like the bombardment of some doomed city.
+ </p>
+ <p>
+ Mr. Jenks and Tom cast one longing look behind at the complicated and
+ expensive machinery that had been installed in the cave by the diamond
+ makers. They had abandoned it, and in it lay the secret of making precious
+ gems. But there was no time to stop now, and investigate.
+ </p>
+ <p>
+ &ldquo;This way,&rdquo; urged Bill Renshaw. &ldquo;We'll soon be out.&rdquo;
+ </p>
+ <p>
+ &ldquo;But won't it be dangerous to go outside?&rdquo; asked Mr. Damon. &ldquo;Shan't we be
+ struck by lightning? There is some protection in here.&rdquo;
+ </p>
+ <p>
+ &ldquo;None at all,&rdquo; said Mr. Parker, quickly. &ldquo;This mountain is a natural
+ lightning rod. To stay here in this cave will be sure death when the storm
+ gets directly over it. And that will be very soon. We must get on
+ insulated ground. Is there any part of this mountain that does not contain
+ iron ore?&rdquo; the scientist asked of the former spirit.
+ </p>
+ <p>
+ &ldquo;Yes; the way out by which we are going lands on a dirt hill.&rdquo;
+ </p>
+ <p>
+ &ldquo;That's good; then we may be saved.&rdquo;
+ </p>
+ <p>
+ On they ran. They had no lanterns, but the blue light of the electricity,
+ as it leaped from point to point inside the cave, where there were
+ outcroppings of iron ore, made the place bright enough to see.
+ </p>
+ <p>
+ &ldquo;Here we are!&rdquo; cried Bill Renshaw at length. &ldquo;Here's the way out!&rdquo;
+ </p>
+ <p>
+ Making a sudden turn in the winding passage he showed the adventurers a
+ small opening in the side of the crag. In an instant they had passed
+ through, and found themselves in daylight once more. The sudden glare
+ almost blinded them, for, though the sky was overcast by clouds, from
+ which jagged tongues of lightning played, the outside was much lighter
+ than the dark cave.
+ </p>
+ <p>
+ &ldquo;I should say it was a storm!&rdquo; cried Tom Swift. &ldquo;See, it is striking every
+ minute, and all around us!&rdquo;
+ </p>
+ <p>
+ In fact, lightning bolts were falling on every side of the adventurers.
+ Every time the balls of fire struck, they burst open great stones, or
+ seared a livid scar on the face of some cliff. As for Tom and the others,
+ they stood on a dry dirt hill, in which, fortunately, there was no iron
+ ore. To this fact they undoubtedly owed their lives, though had there been
+ rain, to moisten the ground and make the earth a good conductor of
+ electricity, they probably would have been badly shocked. But the
+ electrical outburst was not accompanied by rain.
+ </p>
+ <p>
+ Tom looked up. He saw a compact mass of cloud moving toward the summit of
+ the mountain on the slope of which they stood. From this cloud there
+ played shafts of reddish-green fire.
+ </p>
+ <p>
+ &ldquo;Look!&rdquo; called the young inventor to Mr. Parker. The instant the latter
+ saw the cloud, he cried:
+ </p>
+ <p>
+ &ldquo;We must get away from here by all means! That is the center of the storm.
+ As soon as it gets over the mountain, where that lightning rod is, all the
+ electrical fluid will be discharged in one bolt at the mountain, and it
+ will be destroyed! We must run, but keep on the dirt places! Run for your
+ lives!&rdquo;
+ </p>
+ <p>
+ They needed no second warning. Turning, they fled down the steep side of
+ the mountain, slipping and stumbling, but taking care not to step on any
+ iron ore. Behind them flashed the lightning bolts.
+ </p>
+ <p>
+ Suddenly there was a most awful crash. It seemed as if the end of the
+ world had come, and the ear drums of Tom and his companion almost burst
+ with the fearful report. The concussion knocked them down, and they lay
+ stunned for a moment.
+ </p>
+ <p>
+ Following the terrible report there was a low, rumbling sound. Hardly
+ knowing whether he was dead or alive, Tom opened his eyes and looked about
+ him. What he saw caused him to cry out in terror.
+ </p>
+ <p>
+ The whole mountain seemed bathed in fire. Great blue, red and green
+ flashes played around it. Then the towering cliff seemed to melt and
+ crumble up, and the great peak, the top of it containing the diamond
+ makers' cave, from which they had fled but a few minutes before, the
+ entire summit was toppled over into the valley on the other side, and in
+ the direction opposite to that where the adventurers stood.
+ </p>
+ <p>
+ Then came a profound silence, and the lightning ceased. The storm was
+ over, and only the rattle of stones and boulders, as they came to rest in
+ the valley below, reached the ears of our friends.
+ </p>
+ <p>
+ &ldquo;Phantom Mountain has been destroyed, just as I said it would be,&rdquo; spoke
+ Mr. Parker, solemnly. Once more he had prophesied correctly.
+ </p>
+ <p>
+ For a few minutes the adventurers hardly knew what to say. They arose
+ awkwardly from the ground where the shock had tossed them. Then Tom
+ remarked, as calmly as possible:
+ </p>
+ <p>
+ &ldquo;Well, it's all over. I guess we may as well get back to our airship.&rdquo;
+ </p>
+ <p>
+ &ldquo;What became of Munson and the others?&rdquo; asked Mr. Damon.
+ </p>
+ <p>
+ Mr. Jenks pointed to the trail, far below. The figures of some men,
+ running madly, could be seen.
+ </p>
+ <p>
+ &ldquo;There they go,&rdquo; he said; &ldquo;I fancy we have seen the last of them.&rdquo; And
+ they had, for some time at least.
+ </p>
+ <p>
+ There was little use lingering any longer on Phantom Mountain&mdash;indeed
+ little of it was left on which to remain. Looking back toward the place
+ where the cave had been, Tom and the others started forward again. The
+ diamond-making machinery had all been destroyed. So, also, had the
+ finished diamonds stored in the cavern and the large supply which had
+ probably been made by the last terrific crash. No one would ever have them
+ now. Tom and Mr. Jenks felt a sense of disappointment, but they were glad
+ to have escaped with their lives. They sought their former camp, but the
+ tent and all their food was buried under tons of earth and rocks.
+ </p>
+ <p>
+ Three days later, after rather severe hardships, they were near the place
+ where they had left the Red Cloud. They had suffered cold and hunger, for
+ they had no food supplies, and, had it not been that Bill Renshaw knew the
+ haunts of some game, of which they managed to snare some, they would have
+ fared badly, for they had left their guns in the cave.
+ </p>
+ <p>
+ &ldquo;Well, there are the trees behind which I hope my airship is hidden,&rdquo;
+ announced Tom, as they came to the spot. &ldquo;Good old Red Cloud! Maybe we
+ won't do some eating when we get aboard, eh?&rdquo;
+ </p>
+ <p>
+ &ldquo;Bless my appetite! but we certainly will!&rdquo; cried Mr. Damon.
+ </p>
+ <p>
+ &ldquo;There's somebody walking around the place,&rdquo; spoke Mr. Jenks.
+ </p>
+ <p>
+ &ldquo;I hope it's no one who has damaged the ship,&rdquo; came from Tom,
+ apprehensively. He broke into a run, and soon confronted an aged miner,
+ who seemed to have established a rude sort of camp near the airship.
+ </p>
+ <p>
+ &ldquo;Is anything the matter?&rdquo; asked Tom, breathlessly. &ldquo;Is my airship all
+ right?&rdquo;
+ </p>
+ <p>
+ &ldquo;I guess she's all right, stranger,&rdquo; was the reply. &ldquo;I don't know much
+ about these contraptions, but I haven't touched her. I knowed she was an
+ airship, for I've seen pictures of 'em, and I've been waiting until the
+ owner came along.&rdquo;
+ </p>
+ <p>
+ &ldquo;Why?&rdquo; asked Tom, wonderingly.
+ </p>
+ <p>
+ &ldquo;Because I've got a proposition to make to you,&rdquo; went on the miner, who
+ said his name was Abe Abercrombie. &ldquo;I've been a miner for a good many
+ years, and I'm just back from Alaska, prospecting around here. I haven't
+ had any luck, but I know of a gold mine in Alaska that will make us all
+ rich. Only it needs an airship to get to it, and I've been figuring how to
+ hire one. Then I comes along, and I sees this big one, and I makes up my
+ mind to stay here until the owners come back. That's what I've done. Now,
+ if I prove that I'm telling the truth, will you go to Alaska&mdash;to the
+ valley of gold with me?&rdquo;
+ </p>
+ <p>
+ &ldquo;I don't know,&rdquo; answered Tom, to whom the proposition was rather sudden.
+ &ldquo;We've just had some pretty startling adventures, and we're almost
+ starved. Wait until we get something to eat, and we'll talk. Come aboard
+ the Red Cloud,&rdquo; and the lad led the way to his craft which was in as good
+ condition as when he left it to go to the diamond cave. Later he listened
+ to the miner's story.
+ </p>
+ <p>
+ Tom Swift did go to the valley of gold in Alaska, and what happened to him
+ and his companions there will be told of in the next volume of this
+ series, to be called &ldquo;Tom Swift in the Caves of Ice; or, the Wreck of the
+ Airship.&rdquo;
+ </p>
+ <p>
+ It did not take our friends long, after they had eaten a hearty meal, to
+ generate some fresh gas, and start the Red Cloud on her homeward way. Tom
+ wanted to take Bill Renshaw with him, but the old man said he would rather
+ remain among the mountains where he had been born. So, after paying him
+ well for his services, they said good-by to him. Abercrombie, the miner,
+ also remained behind, but promised to call and see Tom in a few months.
+ </p>
+ <p>
+ &ldquo;Well, we didn't make any money out of this trip,&rdquo; observed Mr. Jenks,
+ rather dubiously, as they were nearing Shopton, after an uneventful trip.
+ &ldquo;I guess I owe you considerable, Tom Swift. I promised to get you a lot of
+ diamonds, but all I have are those I had from my first visit to the cave.&rdquo;
+ </p>
+ <p>
+ &ldquo;Oh, that's all right,&rdquo; spoke Tom, easily. &ldquo;The experience was worth all
+ the trip cost.&rdquo;
+ </p>
+ <p>
+ &ldquo;Speaking of diamonds, look here!&rdquo; exclaimed Mr. Damon, suddenly, and he
+ pulled out a double handful.
+ </p>
+ <p>
+ &ldquo;Where did you get them?&rdquo; cried the others in astonishment.
+ </p>
+ <p>
+ &ldquo;I grabbed them up, as we ran from the cave,&rdquo; said the eccentric man;
+ &ldquo;but, bless my gaiters! I forgot all about them until you spoke. We'll
+ share them.&rdquo;
+ </p>
+ <p>
+ These diamonds, some of which were large, proved very valuable, though the
+ total sum was far below what Mr. Jenks hoped to make when he started on
+ the remarkable trip. Tom gave Mary Nestor a very fine stone, and it was
+ set in a ring, instead of a pin, this time.
+ </p>
+ <p>
+ On their arrival in Shopton, where Mr. Swift, the housekeeper, Mr. Jackson
+ and Eradicate Sampson were much alarmed for Tom's safety, an attempt was
+ made to manufacture diamonds, using a powerful electric current instead of
+ lightning. But it was not a success, and so Mr. Jenks concluded to give up
+ his search for the secret which was lost on Phantom Mountain.
+ </p>
+ <p>
+ And now we will take leave of Tom Swift, to meet him again soon in other
+ adventures he is destined to have in the caves of ice and the valley of
+ gold.

+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.

+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+
+
+"Well, Tom Swift, I don't believe you will make any mistake if you buy
+that diamond," said the jeweler to a young man who was inspecting a tray
+of pins, set with the sparkling stones. "It is of the first water, and
+without a flaw."
+
+"It certainly seems so, Mr. Track. I don't know much about diamonds, and
+I'm depending on you. But this one looks to be all right."
+
+"Is it for yourself, Tom?"
+
+"Er--no--that is, not exactly," and Tom Swift, the young inventor of
+airships and submarines, blushed slightly.
+
+"Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I think she
+would like a pin of this sort. True, it's rather expensive, but--"
+
+"No, it isn't for Mrs. Baggert, Mr. Track," and Tom seemed a bit
+embarrassed.
+
+"No? Well, then, Tom--of course it's none of my affair, except to
+sell you a good stone, But if this brooch is for a young lady, I can't
+recommend anything nicer. Do you think you will take this; or do you
+prefer to look at some others?"
+
+"Oh, I think this will do, Mr. Track. I guess I'll take--"
+
+Tom's words were interrupted by a sudden action on the part of the
+jeweler. Mr. Track ran from behind the showcase and hastened toward the
+front door.
+
+"Did you see him, Tom?" he cried. "I wonder which way he went?"
+
+"Who?" asked the lad, following the shopkeeper.
+
+"That man. He's been walking up and down in front of my place for the
+last ten minutes--ever since you've been in here, in fact, and I don't
+like his looks."
+
+"What did he do?"
+
+"Nothing much, except to stare in here as if he was sizing my place up."
+
+"Sizing it up?"
+
+"Yes. Getting the lay of the land, so he or some confederate could
+commit a robbery, maybe."
+
+"A robbery? Do you think that man was a thief?"
+
+"I don't know that he was, Tom, and yet a jeweler has to be always
+on the watch, and that isn't a joke, either, Tom Swift. Swindlers and
+thieves are always on the alert for a chance to rob a jewelry store, and
+they work many games."
+
+"I didn't notice any particular man looking in here," said Tom, who
+still held the diamond brooch in his hand.
+
+"Well I did," went on the jeweler. "I happened to glance out of the
+window when you were looking at the pins, and I saw his eyes staring in
+here in a suspicious manner. He may have a confederate with him, and,
+when you're gone, one may come in, and pretend to want to look at some
+diamonds. Then, when I'm showing him some, the other man will enter,
+engage my attention, and the first man will slip out with a diamond ring
+or pin. It's often done."
+
+"You seem to have it all worked out, Mr. Track," observed the lad, with
+a smile. "How do you know but what I'm in with a gang of thieves, and
+that I'm only pretending to want to buy a diamond pin?"
+
+"Oh, I guess I haven't known you, Tom Swift, ever since you were
+big enough to toddle, not to be sure about what you're up to. But I
+certainly didn't like the looks of that man. However, let's forget about
+him. He seems to have gone down the street, and, after all, perhaps I
+was mistaken. Just wait until I show you a few more styles before you
+decide. The young lady may like one of these," and the jeweler went to
+another showcase and took out some more trays of brooches.
+
+"What makes you think she's a young lady, Mr. Track?" asked the lad.
+
+"Oh, it's easy guessing, Tom. We jewelers are good readers of character.
+I can size up a young fellow coming in here to buy an engagement or a
+wedding ring, as soon as he enters the door. I suppose you'll soon be
+in the market for one of those, Tom, if all the reports I hear about you
+are true--you and a certain Mary Nestor."
+
+"I--er--I think I don't care for any of these pins," spoke Tom, quickly,
+with a blush. "I like the first lot best. I think I'll take the one I
+had in my hand when that man alarmed you. Ha! That's odd! What did I do
+with it?"
+
+Tom looked about on the showcase, and glanced down on the floor. He had
+mislaid the brooch, but the jeweler, with a laugh, lifted it out of a
+tray a moment later.
+
+"I saw you lay it down," he said. "We jewelers have to be on the watch.
+Here it is. I'll just put it in a box, and--"
+
+With an exclamation, Mr. Track gave a hasty glance toward his big show
+window. Tom looked up, and saw a man's face peering in. At the sight of
+it, he, too, uttered a cry of surprise.
+
+The next instant the man outside knocked on the glass, apparently with
+a piece of metal, making a sharp sound. As soon as he heard it, the
+jeweler once more sprang from behind the showcase, and leaped for the
+door crying:
+
+"There's the thief! He's trying to cut a hole through my show window and
+reach in and get something! It's an old trick. I'll get the police! Tom,
+you stay here on guard!" and before the lad could utter a protest, the
+jeweler had opened the door, and was speeding down the street in the
+gathering darkness.
+
+Tom stared about him in some bewilderment. He was left alone in charge
+of a very valuable stock of jewelry, the owner of which was racing after
+a supposed thief, crying:
+
+"Police! Help! Thieves! Stop him, somebody!"
+
+"This is a queer go," mused Tom. "I wonder who that man was? He looked
+like somebody I know, and yet I can't seem to place his face. I
+wonder if he was trying to rob the place? Maybe there's another one--a
+confederate--around here."
+
+This thought rather alarmed Tom, so he went to the door, and looked up
+and down the street. He could see no suspicious characters, but in the
+direction in which the jeweler was running there was a little throng of
+people, following Mr. Track after the man who had knocked on the window.
+
+"I wish I was there, instead of here," mused the lad. "Still I can't
+leave, or a thief might come in. Perhaps that was the game, and one of
+the gang is hanging around, hoping the store will be deserted, so he can
+enter and take what he likes."
+
+Tom had read of such cases, and he at once resolved that he would not
+only remain in the jewelry shop, but that he would lock the door, which
+he at once proceeded to do. Then he breathed easier.
+
+The town of Shopton, in the outskirts of which Tom lived with his
+father, and where the scene above narrated took place, was none too well
+lighted at night, and the lad had his doubts about the jeweler catching
+the oddly-acting man, especially as the latter had a good start.
+
+"But some one may head him off," reasoned Tom. "Though if they do catch
+him, I don't see what they can prove against him. Hello, here I am
+carrying this diamond pin around. I might lose it. Guess I'll put it
+back on the tray."
+
+He replaced in the proper receptacle one of the pins he had been
+examining when the excitement occurred.
+
+"I wonder if Mary will like that?" he said, softly. "I hope she does.
+Perhaps it would be better if she could come here herself and pick out
+one--"
+
+Tom's musing was suddenly interrupted by a sharp tattoo on the glass
+door of the jewelry shop. With a start, he looked up, to see staring in
+on him the face of the man who had been there before--the man of whom
+the jeweler was even then in chase.
+
+"Why--why----" stammered Tom.
+
+The man knocked again.
+
+"Tom--Tom Swift!" he called. "Don't you know me?"
+
+"Know you--you?" repeated the lad.
+
+"Yes--don't you remember Earthquake Island--how we were nearly killed
+there--don't you remember Mr. Jenks?"
+
+"Mr. Jenks?"
+
+Tom was so startled that he could only repeat words after the strange
+man, who was talking to him from outside the glass door.
+
+"Yes, Mr. Jenks," was the reply. "Mr. Barcoe Jenks, who makes diamonds.
+I saw you in the store about to buy a diamond--I wanted to tell you not
+to--I'll give you a better diamond than you can buy--I just arrived in
+this place--I must have a private talk with you--Come out--I'll share a
+wonderful secret with you."
+
+A flood of memory came to Tom. He did recall the very strange man who
+walked around Earthquake Island--where Tom and some friends had been
+marooned recently--walked about with a pocketful of what he said were
+diamonds. Now Barcoe Jenks was here.
+
+"I must see you privately, Tom Swift," went on Mr. Jenks, as he once
+more tapped on the glass. "Don't waste money buying diamonds, when you
+and I can make better ones. Where can I have a talk with you? I--" Mr.
+Jenks suddenly looked down the dimly-lighted street. "They're coming
+back!" he cried. "I don't want to be seen. I'll call at your house later
+to-night--be on the watch for me--until then--good-by!"
+
+He waved his hand, and was gone in an instant. Tom stood staring at the
+glass door. He hardly knew whether to believe it or not--perhaps it was
+all a dream.
+
+He pinched himself to make sure that he was awake. Very substantial
+flesh met his thumb and finger, and he felt the pain.
+
+"I'm awake all right," he murmured. "But Barcoe Jenks here--and still
+talking that nonsense about his manufactured diamonds. I think he must
+be crazy. I wonder--"
+
+Once more the lad's musing was interrupted. He heard a murmur of excited
+voices outside the store, on the street. Then the door of the jewelry
+shop was tried. Mr. Track's face was pressed against the glass.
+
+"Open the door! Let me in, Tom!" he called. "I've caught the thief," and
+as the lad unlocked the portal he saw that the jeweler held by the arm
+a ragged lad. "Ah; you scoundrel! I've caught you!" cried the diamond
+merchant, shaking the small chap, while Tom looked on, more mystified
+than ever.
+
+
+
+
+CHAPTER II--A MIDNIGHT VISIT
+
+
+While Mr. Track, the jeweler, and several citizens, attracted by the
+chase after the supposed thief, are crowded into the store, anxious to
+hear explanations of the strange affair, I will take the opportunity to
+tell you something of Tom Swift, the lad who is to figure in this story.
+
+Many of you have already made his acquaintance, when he has been
+speeding about in his airship or fast electric runabout, and to others
+we will state that our hero first made his bow to the public in the
+book called "Tom Swift and His Motor-Cycle," the initial volume of this
+series.
+
+In that story there was related how Tom made the acquaintance of an
+odd individual, named Mr. Wakefield Damon, who was continually blessing
+himself, some part of his anatomy, or his possessions. Mr. Damon was
+riding a motor-cycle, and it started to climb a tree, to his pain and
+fright. Afterward Tom purchased the machine, and had many adventures
+on it, including a chase after a gang of men who had stolen a valuable
+patent model belonging to Mr. Swift.
+
+Mr. Swift and his son were both inventors. They lived together in a
+fine house in the suburbs of Shopton, New York, and with them dwelt Mrs.
+Baggert, the housekeeper (for Tom's mother was dead), and also Garret
+Jackson, an expert engineer, who aided the young inventor and his father
+in perfecting many machines.
+
+There was also another semi-member of the household, to wit, Eradicate
+Sampson, an eccentric colored man, who owned a mule called Boomerang.
+Eradicate did odd jobs around the place, and the mule assisted his
+owner--that is when the mule felt like it.
+
+In the second volume of the series, entitled "Tom Swift and His
+Motor-Boat," there was related the incidents following a pursuit after
+a gang of unprincipled men, who sought to get possession of some of Mr.
+Swift's patents, and it was while in this boat that Tom, his father, and
+a friend, Ned Newton, rescued from Lake Carlopa a Mr. John Sharp, who
+fell from his burning balloon. Mr. Sharp was a skilled aeronaut, and
+after his recovery he joined Tom in building a big airship, called the
+Red Cloud. Tom's adventures in this craft are set down in detail in the
+third volume of the series, called "Tom Swift and His Airship." Not only
+did he and Mr. Sharp and Mr. Damon make a great trip, but they captured
+some bank robbers, and incidentally cleared themselves from the
+imputation of having looted the vault of seventy-five thousand dollars,
+which charge was fostered by a certain Mr. Foger, and his son Andy, who
+was Tom's enemy.
+
+Not satisfied with having conquered the air, Tom and his father set
+to work to gain a victory over the ocean. They built a boat that could
+navigate under water, and, in the fourth book of the series, called "Tom
+Swift and His Submarine Boat," you will find an account of how they went
+under the ocean to secure a sunken treasure, and the fight they had with
+their enemies who sought to get it away from them. They went through
+many perils, not the least of which was capture by a foreign warship.
+
+In the fifth book, entitled "Tom Swift and His Electric Runabout," there
+was told the story of a wonderfully speedy electric automobile the young
+inventor constructed, and how he made a great race in it, and saved from
+ruin a bank, in which his father and Mr. Damon were interested.
+
+Tom's ability as an inventor had, by this time, become well known. One
+day, as related in a volume called "Tom Swift and His Wireless Message,"
+he received a letter from a Mr. Hosmer Fenwick, of Philadelphia, asking
+his aid in perfecting an airship which the resident of the Quaker
+City had built, but which would not work. In his small monoplane, the
+Butterfly, Tom and Mr. Damon went to Philadelphia, as Mr. Damon was
+acquainted with Mr. Fenwick.
+
+Tom carefully inspected the Whizzer which was the name of Mr. Fenwick's
+airship, and, after some difficulties, succeeded in getting the electric
+craft in shape to make a flight.
+
+Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape May in the
+Whizzer, but were caught in a terrific storm, and blown out to sea.
+The wind became a hurricane, the airship was disabled, and wrecked in
+mid-air. When it fell to earth it landed on one of the small West Indian
+islands, but what was the terror of the three castaways to find that the
+island was subject to earthquake shocks.
+
+But the earth-tremors were not the only surprise in store for Tom and
+his two friends, On the island they found five men and two ladies, who,
+by strange chance, had been stranded there when the yacht Resolute,
+owned by Mr. George Hosbrook, was wrecked in the same storm that
+disabled the airship. Mr. Hosbrook, a millionaire, was taking a party of
+friends to the West Indies.
+
+When the castaways (among whom were Mr. and Mrs. Amos Nestor, parents
+of Mary Nestor, a girl of whom Tom was very fond) found that there was
+danger of the island being destroyed in an earthquake, they were in
+despair. There seemed no way of being rescued, as the island was out of
+the line of regular ship travel.
+
+Tom, however, was resourceful. With the electrical apparatus from the
+wrecked airship, he built a wireless plant, and sent messages for help,
+broadcast over the ocean.
+
+They were finally heard, and answered, by an operator on board the
+steamer Camberanian, which came on under forced draught, and rescued
+Tom and his friends. It was only just in time, for, no sooner had
+they gotten aboard the steamer in lifeboats, than the whole island was
+destroyed by an earthquake shock.
+
+But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the
+others, got safely home. Among the survivors from the yacht Resolute
+was a Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom
+through the glass window of the jewelry store. Mr. Jenks was a peculiar
+man. Tom discovered this on Earthquake Island. Mr. Jenks carried with
+him some stones which he said were diamonds. He asserted that he had
+made them, but Tom did not know whether or not to believe this.
+
+When it seemed that the castaways would not be saved Mr. Jenks offered
+Tom a large sum in these same diamonds for some plan whereby he might
+escape the earthquakes. Mr. Jenks said there was a certain secret in
+connection with the manufactured diamonds that he had to solve--that he
+had been defrauded of his rights--and that a certain Phantom Mountain
+figured in it. But Tom, at that time, paid little attention to Mr.
+Jenks' talk. The time was to come, however, when he would attach much
+importance to it.
+
+When this story opens, Tom was more interested in Mr. Barcoe Jenks than
+in any one else, and was wondering what he wanted to see him about. The
+young inventor could not quite understand how Mr. Track, the jeweler,
+could come back with a lad he suspected of being a thief, when the
+person who had acted so suspiciously, and who had knocked on the glass,
+was the queer man, Mr. Jenks.
+
+"Yes, Tom I caught him," the jeweler went on. "I chased after him, and
+nabbed him. It was hard work, too, for I'm not a good runner. Now, you
+little rascal, tell me why you tried to rob my store?" and the diamond
+merchant shook the lad roughly.
+
+"I--I didn't try to rob your store," was the timid answer.
+
+"Well, perhaps you didn't, exactly, but your confederates did. Why did
+you rap on the glass, and why were you staring in so intently?"
+
+"I wasn't lookin' in."
+
+"Well, if it wasn't you, it was some one just like you. But why did you
+run when I raced down the street?"
+
+"I--I don't know," and the lad began to snivel. "I--I jest ran--that's
+all--'cause I see everybody else runnin', an' I thought there was a
+fire."
+
+"Ha! That's a likely story! You ran because you are guilty! I'm going to
+hand you over to the police."
+
+"Did he get anything, Mr. Track?" asked one of the men who had joined
+the jeweler in the chase.
+
+"No, I can't say that he did. He didn't get a chance. Tom Swift was
+in here at the time. But this fellow was only waiting for a chance to
+steal, or else to aid his confederates."
+
+"But, if he didn't take anything, I don't see how you can have him
+arrested," went on the man.
+
+"On suspicion; that's how!" asserted Mr. Track. "Will some one get me a
+constable?"
+
+"I wouldn't call a constable," said Tom, quietly.
+
+"Why not?"
+
+"Because that isn't the person who looked in your window."
+
+"How do you know, Tom?"
+
+"Because that person came back while you were out. I saw him."
+
+"You saw him? Did he try to steal any of my diamonds, Tom?"
+
+"No, I guess he doesn't need any."
+
+"Why not?" There was wonder in the jeweler's tone.
+
+"Why, he claims he can make all he wants."
+
+"Make diamonds?"
+
+"So he says."
+
+"Why, he must be crazy!" and Mr. Track laughed.
+
+"Perhaps he is," admitted Tom, "I'm only telling you what he says. He's
+the person who acted so suspiciously. He came back here, I'm telling
+you, while you were running down the street, and spoke to me."
+
+"Oh, then you know him?" The jeweler's voice was suspicious.
+
+"I didn't at first," admitted Tom. "But when he said he was Mr.
+Barcoe Jenks, I remembered that I had met him when I was cast away on
+Earthquake Island."
+
+"And he says he can make diamonds?" asked Mr. Track.
+
+"What did he want of you?" and the jeweler looked at Tom, quizzically.
+
+"He wanted to have a talk with me," replied the lad, "and when he saw
+me in your store, he tried to attract my attention by knocking on the
+glass."
+
+"That's a queer way to do," declared Mr. Track. "What did he want?"
+
+"I don't know exactly," answered Tom, not caring to go into details just
+then. "But I'm sure, Mr. Track, that you've got the wrong person there.
+That lad never looked in the window, nor knocked on the glass."
+
+"That's right--I didn't," asserted the captive.
+
+The jeweler looked doubtful.
+
+"Why did you run?" he asked.
+
+"I told you, I thought there was a fire."
+
+"That's right, I don't believe he's the fellow you want," put in another
+man. "I was standing on the corner, near White's grocery store, and
+I noticed this lad. That was before I heard you yelling, and saw you
+coming, and then I joined in the chase. I guess the man you were after
+got away, Track."
+
+"He did," asserted Tom. "He came back here, a little while ago, and he
+ran away just now, as he heard you coming."
+
+"Where did he go?" asked the jeweler, eagerly.
+
+"I don't know," answered Tom. "Only you've got the wrong lad here."
+
+"Well, perhaps I have," admitted the diamond merchant. "You can go,
+youngster, but next time, don't run if you're not guilty."
+
+"I thought there was a fire," repeated the lad, as he hurriedly slipped
+through the crowd in the store, and disappeared down the dark street.
+
+"Well, I guess the excitement's all over, and, anyhow, you weren't
+robbed, Track," said a stout man, as he left the store. The others soon
+followed, and Tom and the jeweler were once more alone in the shop.
+
+"Can you tell me something about this man, Tom?" asked Mr. Track,
+eagerly. "So he really makes diamonds. Who is he?"
+
+"I'd rather not tell--just now," replied the young inventor. "I don't
+take much stock in him, myself. I think he's visionary. He may think he
+has made diamonds, and he may have made some stones that look like them.
+I'm very skeptical."
+
+"If you could bring me some, Tom, I could soon tell whether they were
+real or not. Can you?"
+
+The lad shook his head.
+
+"I don't expect to see Mr. Jenks again," he said. "He talked
+rather wildly about waiting to meet me, but that man is odd--crazy,
+perhaps--and I don't imagine I'll see him. He's harmless, but he's
+eccentric. Well, there was quite some excitement for a time."
+
+"I should say there was. I thought it was a plan to rob me," and the
+jeweler began putting away the diamond pins. In fact, the excitement
+so filled the minds of himself and Tom that neither of them thought any
+more of the object of the lad's visit, and the young inventor departed
+without purchasing the pin he had come after.
+
+It was not until he was out on the street, walking toward his home, that
+the matter came back to his mind.
+
+"I declare!" he exclaimed. "I didn't get that pin for Mary, after all!
+Well, never mind, I have a week until her birthday, and I can get it
+to-morrow."
+
+He walked rapidly toward home, for the weather looked threatening, and
+Tom had no umbrella. He was musing on the happenings of the evening when
+he reached his house. His father was out, as was Garret Jackson, the
+engineer; and Mrs. Baggert, the housekeeper, was entertaining a lady in
+the sitting-room, so, as Tom was rather tired, he went directly to his
+own room, and, a little later got into bed.
+
+It was shortly after midnight when he was awakened by hearing a rattling
+on the window of his room. The reason he was able to fix the time
+so accurately was because as soon as he awakened he pressed a little
+electric button, and it illuminated the face of a small clock on his
+bureau. The hands pointed to five minutes past twelve.
+
+"Humph! That sounds like hail!" exclaimed Tom, as he arose, and looked
+out of the casement. "I wonder if any of the skylights of the airship
+shed are open? There might be some damage. Guess I'd better go out and
+take a look."
+
+He had mentally reasoned this far before he had looked out, and when
+he saw that the moon was brightly shining in a clear sky, he was a bit
+surprised.
+
+"Why--that wasn't hail," he murmured. "It isn't even raining. I wonder
+what it was?"
+
+He was answered a moment later, for a shower of fine gravel from the
+walk flew up and clattered against the glass. With a start, Tom looked
+down, and saw a dark figure standing under an apple tree.
+
+"Hello! Who's there?" called the lad, after he had raised the sash.
+
+"It's I--Mr. Jenks," was the surprising answer.
+
+"Mr. Jenks?" repeated Tom.
+
+"Yes--Barcoe Jenks, of Earthquake Island."
+
+"You here? What do you want?"
+
+"Can you come down?"
+
+"What for?"
+
+"Tom Swift, I've something very important to tell you," was the answer
+in a low voice, yet which carried to Tom's ears perfectly. "Do you want
+to make a fortune for yourself--and for me?"
+
+"How?" Tom was beginning to think more and more that Mr. Jenks was
+crazy.
+
+"How? By helping me to discover the secret of Phantom Mountain, where
+the diamonds are made! Will you?"
+
+"Wait a minute--I'll come down," answered Tom, and he began to grope for
+his clothes in the dim light of the little electric lamp.
+
+What was the secret of Phantom Mountain? What did Mr. Jenks really want?
+Could he make diamonds? Tom asked himself these questions as he hastily
+dressed to go down to his midnight visitor.
+
+
+
+
+CHAPTER III--A STRANGE STORY
+
+
+"Well, Mr. Jenks," began Tom, when he had descended to the garden, and
+greeted the man who had acted so strangely on Earthquake Island, "this
+is rather an odd time for a visit."
+
+"I realize that, Tom Swift," was the answer, and the lad noticed that
+the man spoke much more calmly than he had that evening at the jewelry
+shop. "I realize that, but I have to be cautious in my movements."
+
+"Why?"
+
+"Because there are enemies on my track. If they thought I was seeking
+aid to discover the secret of Phantom Mountain, my life might pay the
+forfeit."
+
+"Are you in earnest, Mr. Jenks?"
+
+"I certainly am, and, while I must apologize for awakening you at this
+unseemly hour, and for the mysterious nature of my visit, if you will
+let me tell my story, you will see the need of secrecy."
+
+"Oh, I don't mind being awakened," answered Tom, good-naturedly, "but
+I will be frank with you, Mr. Jenks. I hardly can believe what you have
+stated to me several times--that you know how diamonds can be made."
+
+"I can prove it to you," was the quiet answer.
+
+"Yes, I know. For centuries men have tried to discover the secret of
+transmuting base metals into gold, and how to make diamonds by chemical
+means. But they have all been failures."
+
+"All except this process--the process used at Phantom Mountain,"
+insisted the queer man. "Do you want to hear my story?"
+
+"I have no objections."
+
+"Then let me warn you," went on Mr. Jenks, "that if you do hear it, you
+will be so fascinated by it that I am sure you will want to cast your
+lot in with mine, and aid me to get my rights, and solve the mystery.
+And I also want to warn you that if you do, there is a certain amount of
+danger connected with it."
+
+"I'm used to danger," answered Tom, quietly. "Let me hear your story.
+But first explain how you came to come here, and why you acted so
+strangely at the jewelry store."
+
+"Willingly. I tried to attract your attention at the store, because I
+saw that you were going to buy a diamond, and I didn't want you to."
+
+"Why not?"
+
+"Because I want to present you with a beautiful stone, that will answer
+your purpose as well or better, than any one you could buy. That will
+prove my story better than any amount of words or argument. But I could
+not attract your attention without also attracting that of the jeweler.
+He became suspicious, gave chase, and I thought it best to vanish. I
+hope no one was made to suffer for what may have been my imprudence."
+
+"No, the lad whom Mr. Track caught was let go. But how did you happen to
+come to Shopton?"
+
+"To see you. I got your address from the owner of the yacht Resolute. I
+knew that if there was one person who could aid me to recover my rights,
+it would be you, Tom Swift. Will you help me? Will you come with me to
+discover the secret of Phantom Mountain? If we go, it will have to be in
+an airship, for in no other way, I think, can we come upon the place, as
+it is closely guarded. Will you come? I will pay you well."
+
+"Perhaps I had better hear your story," said the young inventor. "But
+first let me suggest that we move farther away from the house. My
+father, or Mr. Jackson, or the housekeeper, may hear us talking, and it
+may disturb them. Come with me to my private shop," and Tom led the way
+to a small building where he did experimental work. He unlocked the door
+with a key he carried, turned on the lights, which were run by a storage
+battery, and motioned Mr. Jenks to a seat.
+
+"Now I'll hear your story," said Tom.
+
+"I'll make it as short as possible," went on the queer man. "To begin
+with, it is now several years ago since a poorly dressed stranger
+applied to me one night for money enough to get a meal and a bed to
+sleep in. I was living in New York City at the time, and this was
+midnight, as I was returning home from my club.
+
+"I was touched by the man's appearance, and gave him some money. He
+asked for my card, saying he would repay me some day. I gave it to him,
+little thinking I would hear from the man again. But I did. He called
+at my apartments about a week later, saying he had secured work as an
+expert setter of diamonds, and wanted to repay me. I did not want to
+take his money, but the fact that such a sorry looking specimen of
+manhood as he had been when I aided him, was an expert handler of gems
+interested me. I talked with the man, and he made a curious statement.
+
+"This man, who gave his name as Enos Folwell, said he knew a place where
+diamonds could be made, partly in a scientific manner, and partly by the
+forces of nature. I laughed at him, but he told me so many details that
+I began to believe him. He said he and some other friends of his, who
+were diamond cutters, had a plant in the midst of the Rocky Mountains,
+where they had succeeded in making several small, but very perfect
+diamonds. They had come to the end of their rope, though, so to speak,
+because they could not afford to buy the materials needed. Folwell
+said that he and his companions had temporarily separated, had left the
+mountain where they made diamonds, and agreed to meet there later when
+they had more money with which to purchase materials. They had all
+agreed to go out into civilization, and work for enough funds to enable
+them to go on with their diamond making.
+
+"I hardly knew whether to believe the man or not, but he offered proof.
+He had several small, but very perfect diamonds with him, and he gave
+them to me, to have tested in any way I desired.
+
+"I promised to look into the matter, and, as I was quite wealthy, as,
+in fact I am now, and if I found that the stones he gave me were real, I
+said I might invest some money in the plant."
+
+"Were the diamonds good?" asked Tom, who was beginning to be interested.
+
+"They were--stones of the first water, though small. An expert gem
+merchant, to whom I took them, said he had never seen any diamonds like
+them, and he wanted to know where I got them. Of course I did not tell
+him.
+
+"To make a long story short, I saw Folwell again, told him to
+communicate with his companions, and to tell them that I would agree to
+supply the cash needed, if I could share in the diamond making. To this
+they agreed, and, after some weeks spent in preparation, a party of us
+set out for Phantom Mountain."
+
+"Phantom Mountain?" interrupted Tom. "Where is it?"
+
+"I don't know, exactly--it's somewhere in the Rockies, but the exact
+location is a mystery. That is why I need your help. You will soon
+understand the reason. Well, as I said, myself, Folwell and the others,
+who were not exactly prepossessing sort of men, started west. When we
+got to a small town, called Indian Ridge, near Leadville, Colorado,
+the men insisted that I must now proceed in secret, and consent to be
+blindfolded, as they were not yet ready to reveal the secret of the
+place where they made the diamonds.
+
+"I did not want to agree to this, but they insisted, and I gave in,
+foolishly perhaps. At any rate I was blindfolded one night, placed in
+a wagon, and we drove off into the mountains. After traveling for some
+distance I was led, still blindfolded, up a steep trail.
+
+"When the bandage was taken off my eyes I saw that I was in a large
+cave. The men were with me, and they apologized for the necessity that
+caused them to blindfold me. They said they were ready to proceed with
+the making of diamonds, but I must promise not to seek to discover the
+secret until they gave me permission, nor was I to attempt to leave the
+cave. I had to agree.
+
+"Next they demanded that I give them a large sum, which I had promised
+when they showed me, conclusively, that they could make diamonds. I
+refused to do this until I had seen some of the precious stones, and
+they agreed that this was fair, but said I would have to wait a few
+days.
+
+"Well, I waited, and, all that while, I was virtually a prisoner in the
+cave. All I could learn was that it was in the midst of a great range,
+near the top, and that one of the peaks was called Phantom Mountain.
+Why, I did not learn until later.
+
+"At last one night, during a terrific thunder storm, the leader of the
+diamond makers--Folwell--announced that I could now see the stones made.
+The men had been preparing their chemicals for some days previous. I
+was taken into a small chamber of the cave, and there saw quite a
+complicated apparatus. Part of it was a great steel box, with a lever on
+it.
+
+"We will let you make some diamonds for yourself," Folwell said to me,
+and he directed me to pull the lever of the box, at a certain signal.
+The signal came, just as a terrific crash of thunder shook the very
+mountain inside of which we were. The box of steel got red-hot, and when
+it cooled off it was opened, and was given a handful of white stones.
+
+"Were they diamonds?" asked Tom, eagerly.
+
+Mr. Jenks held out one hand. In the palm glittered a large
+stone--ostensibly a diamond. In the rays of the moon it showed all the
+colors of the rainbow--a beautiful gem. "That is one of the stones I
+made--or rather that I supposed I had made," went on Mr. Jenks. "It is
+one of several I have, but they have not all been cut and polished as
+has this one.
+
+"Naturally I was much impressed by what I saw, and, after I had made
+certain tests which convinced me that the stones in the steel box were
+diamonds, I paid over the money as I had promised. That was my undoing."
+
+"How?"
+
+"As soon as the men got the cash, they had no further use for me. The
+next I remember is eating a rude meal, while we discussed the future of
+making diamonds. I knew nothing more until I found myself back in the
+small hotel at Indian Ridge, whence I had gone some time previous, with
+the men, to the cave in the mountain."
+
+"What happened?" asked Tom, much surprised by the unexpected outcome of
+the affair.
+
+"I had been tricked, that was all! As soon as the men had my
+money they had no further use for me. They did not want me to learn the
+secret of their diamond making, and they drugged me, carried me away
+from the cave, and left me in the hotel."
+
+"Didn't you try to find the cave again?"
+
+"I did, but without avail. I spent some time in the Rockies, but no one
+could tell where Phantom Mountain was; in fact, few had heard of it, and
+I was nearly lost searching for it.
+
+"I came back East, determined to get even. I had given the men a
+very large sum of money, and, in exchange, they had given me several
+diamonds. Probably the stones are worth nearly as much as the money I
+invested, but I was cheated, for I was promised an equal share in the
+profits. These were denied me, and I was tricked. I determined to be
+revenged, or at least to discover the secret of making diamonds. It is
+my right."
+
+"I agree with you," spoke Tom.
+
+"But, up to the time I met you on Earthquake Island, I could form no
+plan for discovering Phantom Mountain, and learning the secret of the
+diamond makers," went on Mr. Jenks. "I carried the gems about with me,
+as you doubtless saw when we were on the island. But I knew I needed an
+airship in which to fly over the mountains, and pick out the location of
+the cave where the diamonds are made."
+
+"But how can you locate it, if you were blindfolded when you were taken
+there, Mr. Jenks?"
+
+"I forgot to tell you that, on our journey into the mountains, and just
+before I was carried into the cave, I managed to raise one corner of
+the bandage. I caught a glimpse of a very peculiarly shaped cliff--it
+is like a great head, standing out in bold relief against the moonlight,
+when I saw it. That head of rock is near the cave. It may be the
+landmark by which we can locate Phantom Mountain."
+
+"Perhaps," admitted the young inventor.
+
+"What I want to know is this," went on Mr. Jenks. "Will you go with me
+on this quest--go in your airship to discover the secret of the diamond
+makers? If you will, I will share with you whatever diamonds we can
+discover, or make; besides paying all expenses. Will you go, Tom Swift?"
+
+The young inventor did not know what to answer. How far was Mr. Jenks
+to be trusted? Were the stones he had real diamonds? Was his story,
+fantastical as it sounded--true? Would it be safe for Tom to go?
+
+The lad asked himself these questions. Mr. Jenks saw his hesitation.
+
+"Here," said the strange man, "I will prove what I say. Take this
+diamond. I intended it for you, anyhow, for what you did for me on
+Earthquake Island. Take it, and--and give it to the person for whom you
+were about to purchase a diamond to-night. But, first of all, take it to
+a gem expert, and get his opinion. That will prove the truth of what
+I say, Tom Swift, and I feel sure that you will cast your lot in with
+mine, and help me to discover the secret of Phantom Mountain, and aid me
+to get my rights from the diamond makers!"
+
+
+
+
+CHAPTER IV--ANDY FOGER GETS A FRIGHT
+
+
+Tom Swift considered a few minutes. On the face of it, the proposition
+appealed to him. He had been home some time now after his adventures on
+Earthquake Island, and he was beginning to long for more excitement. The
+search for the mysterious mountain, and the cave of the diamond makers,
+might offer a new field for him. But there came to him a certain
+distrust of Mr. Jenks.
+
+"I don't like to doubt your word," began Tom, slowly, "but you know,
+Mr. Jenks, that some of the greatest chemists have tried in vain to make
+diamonds; or, at best, they have made only tiny ones. To think that any
+man, or set of men, made real diamonds as large as the ones you have,
+doesn't seem--well--" and Tom hesitated.
+
+"You mean you can hardly believe me?" asked Mr. Jenks.
+
+"I guess that's it," assented Tom.
+
+"I don't blame you a bit!" exclaimed the odd man. "In fact, I didn't
+believe it when they told me they could make diamonds. But they proved
+it to me. I'm ready now to prove it to you."
+
+"I'll tell you what I'll do. Here's this one stone, cut ready for
+setting. Here's another, uncut," and Mr. Jenks drew from his pocket
+what looked like a piece of crystal. "Take them to any jeweler," he
+resumed--"to the one in whose place I saw you to-night. I'll abide by
+the verdict you get, and I'll come here to-morrow night, and hear what
+you have to say."
+
+"Why do you come at night?" asked Tom, thinking there was something
+suspicious in that.
+
+"Because my life might be in danger if I was seen talking to you, and
+showing you diamonds in the daytime--especially just now.
+
+"Why at this particular time?"
+
+"For the reason that the diamond makers are on my trail. As long as I
+remained quiet, after their shabby treatment of me, and did not try to
+discover their secret, they were all right. But, after I realized that
+I had been cheated out of my rights, and when I began to make an
+investigation, with a view to discovering their secret whereabouts, I
+received mysterious and anonymous warnings to stop."
+
+"But I did not. I came East, and tried to get help to discover the cave
+of the diamond makers, but I was unsuccessful. I needed an airship, as
+I said, and no person who could operate one, would agree to go with
+me on the quest. Again I received a warning to drop all search for the
+diamond makers, but I persisted, and about a week ago I found I was
+being shadowed."
+
+"Shadowed; by whom?" asked Tom.
+
+"By a man I never remember seeing, but who, I have no doubt, is one of
+the diamond-making gang."
+
+"Do you think he means you harm?"
+
+"I'm sure of it. That is the reason I have to act so in secret, and come
+to see you at night. I don't want those scoundrels to find out what I am
+about to do. On my return from Earthquake Island, I again endeavored to
+interest an airship man in my plan, but he evidently thought me insane.
+Then I thought of you, as I had done before, but I was afraid you, too,
+would laugh at my proposition. However, I decided to come here, and I
+did. It seemed almost providential that my first view of you was in
+a jewelry shop, looking at diamonds. I took it as a good omen. Now it
+remains with you. May I call here to-morrow night, and get your answer?"
+
+Tom Swift made up his mind quickly. After all it would be easy enough to
+find out if the diamonds were real. If they were, he could then decide
+whether or not to go with Mr. Jenks on the mysterious quest. So he
+answered:
+
+"I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow
+night. In the meanwhile, for my own satisfaction, I'll let an expert
+look at these stones."
+
+"Get the greatest diamond expert in the world, and he'll pronounce them
+perfect!" predicted the odd man. "Now I'll bid you goodnight, and be
+going. I'll be here at this time to-morrow."
+
+As Mr. Jenks turned aside there was a movement among the trees in the
+orchard, and a shadowy figure was seen hurrying away.
+
+"Who's that?" asked the diamond man, in a hoarse whisper. "Did you see
+that, Tom Swift? Some one was here--listening to what I said! Perhaps it
+was the man who has been shadowing me!"
+
+"I think not. I guess it was Eradicate Sampson, a colored man who does
+work for us," said Tom. "Is that you, Rad?" he called.
+
+"Yais, sah, Massa Tom, heah I is!" answered the voice of the negro,
+but it came from an entirely different direction than that in which the
+shadowy figure had been seen.
+
+"Where are you, Rad?" called the young inventor.
+
+"Right heah," was the reply, and the colored man came from the direction
+of the stable. "I were jest out seein' if mah mule Boomerang were all
+right. Sometimes he's restless, an' don't sleep laik he oughter."
+
+"Then that wasn't you over in the orchard?" asked Tom, in some
+uneasiness.
+
+"No, sah, I ain't been in de orchard. I were sleepin' in mah shack, till
+jest a few minutes ago, when I got up, an' went in t' see Boomerang.
+I had a dream dat some coon were tryin t' steal him, an' it sort ob
+'sturbed me, laik."
+
+"If it wasn't your man, it was some one else," said Mr. Jenks,
+decidedly.
+
+"We'll have a look!" exclaimed Tom. "Here, Rad, come over and scurry
+among those trees. We just saw some one sneaking around."
+
+"I'll sure do dat!" cried the colored man. "Mebby it were somebody arter
+Boomerang! I'll find 'em."
+
+"I don't believe it was any one after the mule," murmured Mr. Jenks,
+"but it certainly was some one--more likely some one after me."
+
+The three made a hasty search among the trees, but the intruder had
+vanished, leaving no trace. They went out into the road, which the moon
+threw into bold relief along its white stretch, but there was no figure
+scurrying away.
+
+"Whoever it was, is gone," spoke Tom. "You can go back to bed, Rad,"
+for the colored man, of late, had been sleeping in a shack on the Swift
+premises.
+
+"And I guess it's time for me to go, too," added Mr. Jenks. "I'll be
+here to-morrow night, Tom, and I hope your answer will be favorable."
+
+Tom did not sleep well the remainder of the night, for his fitful
+slumbers were disturbed by dreams of enormous caves, filled with
+diamonds, with dark, shadowy figures trying to put him into a red-hot
+steel box. Once he awakened with a start, and put his hand under his
+pillow to feel if the two stones Mr. Jenks had given him, were still
+there. They had not been disturbed.
+
+Tom made up his mind to find out if the stones were really diamonds,
+before saying anything to his father about the chance of going to seek
+Phantom Mountain. And the young inventor wished to get the opinion of
+some other jeweler than Mr. Track--at least, at first.
+
+"Though if this one proves to be a good gem, I'll have Mr. Track set it
+in a brooch, and give it to Mary for her birthday," decided the young
+inventor. "Guess I'll take a run over to Chester in the Butterfly, and
+see what one of the jewelers there has to say."
+
+In addition to his big airship, Red Cloud, Tom owned a small, swift
+monoplane, which he called Butterfly. This had been damaged by Andy
+Foger just before Tom left on the trip that ended at Earthquake Island,
+but the monoplane had been repaired, and Andy had left town, not having
+returned since.
+
+Telling his father that he was going off on a little business trip,
+which he often did in his aeroplane, Tom, with the aid of Mr. Jackson,
+the engineer, wheeled the Butterfly out of its shed.
+
+Adjusting the mechanism, and seeing that it was in good shape, Tom took
+his place in one of the two seats, for the monoplane would carry two.
+Mr. Jackson then spun the propellers, and, with a crackle and roar the
+motor started. Over the ground ran the dainty, little aeroplane, until,
+having momentum enough, Tom tilted the wing planes and the machine
+sailed up into the air.
+
+Rising about a thousand feet, and circling about several times to test
+the wind currents, Tom headed his craft toward Chester, a city about
+fifty miles from Shopton. In his pocket, snugly tucked away, were the
+two stones Mr. Jenks had given him.
+
+It was not long before Tom saw, looming up in the distance the church
+spires and towering factory chimneys of Chester, for his machine was a
+speedy one, and could make ninety miles an hour when driven. But now a
+slower speed satisfied our hero.
+
+"I'll just drop down outside of the city," he reasoned, "for too much
+of a crowd gathers when I land in the street. Besides I might frighten
+horses, and then, too, it's hard to get a good start from the street.
+I'll leave it in some barn until I want to go back."
+
+Tom sent his craft down, in order to pick out a safe place for a
+landing. He was then over the suburbs of the city, and was following the
+line of a straight country road.
+
+"Looks like a good place there," he murmured. "I'll shut off the motor,
+and vol-plane down."
+
+Suiting the action to the word, Tom shut off his power. The little craft
+dipped toward the ground, but the lad threw up the forward planes, and
+caught a current of air that sent him skimming along horizontally.
+
+As he got nearer to the ground, he saw the figure of a lad riding a
+bicycle along the country highway. Something about the figure struck Tom
+as being familiar, and he recognized the cyclist a moment later.
+
+"It's Andy Foger!" said Tom, in a whisper. "I wondered where he had been
+keeping himself since he damaged the Butterfly. Evidently he doesn't
+dare venture back to Shopton. Well, here's where I give him a scare."
+
+Tom's monoplane was making no more noise, now, than a soaring bird. He
+was gliding swiftly toward the earth, and, with the plan in his mind of
+administering some sort of punishment to the bully, he aimed the machine
+directly at him.
+
+Nearer and nearer shot the monoplane, as quietly as a sheet of paper
+might fall. Andy pedaled on, never looking up nor behind him, A moment
+later, as Tom threw up his headplanes, to make his landing more easy,
+and just as he swooped down at one side of the cyclist, our hero let out
+a most alarming yell, right into Andy's ear.
+
+"Now I've got you!" he shouted. "I'll teach you to slash my aeroplane!
+Come with me!"
+
+Andy gave one look at the white bird-like apparatus that had flown up
+beside him so noiselessly, and, being too frightened to recognize Tom's
+voice, must have thought that he had been overtaken by some supernatural
+visitor.
+
+Andy gave a yell like an Indian, about to do a stage scalping act, and
+fairly dived over the handlebars of his bicycle, sprawling in a heap on
+the dusty road.
+
+"I guess that will hold you for a while," observed Tom, grimly, as he
+put on the ground-brake and brought his monoplane to a stop not far from
+the fallen rider.
+
+
+
+
+CHAPTER V--A MYSTERIOUS MAN
+
+
+For several minutes Andy Foger did not arise. He remained prostrate in
+the dust, and Tom, observing him, thought perhaps the bully might have
+been seriously injured. But, a little later, Andy cautiously raised his
+head, and inquired in a frightened voice:
+
+"Is it--is it gone?"
+
+"Is what gone?" asked Tom, grimly.
+
+At the sound of his voice, Andy looked up. "Was that you, Tom Swift?" he
+demanded. "Did you knock me off my wheel?"
+
+"My monoplane and I together did," was the reply; "or, rather, we
+didn't. It was the nervous reaction caused by your fright, and
+the knowledge that you had done wrong, that made you jump over the
+handlebars. That's the scientific explanation."
+
+"You--you did it!" stammered Andy, getting to his feet. He wasn't hurt
+much, Tom thought.
+
+"Have it your own way," resumed our hero. "Did you think it was a
+hob-goblin in a chariot of fire after you, Andy?"
+
+"Huh! Never mind what I thought! I'll have you arrested for this!"
+
+"Will you? Delighted, as the boys say. Hop in my airship and I'll take
+you right into town. And when I get you there I'll make a charge of
+malicious mischief against you, for breaking the propeller of the
+Butterfly and slashing her wings. I've mended her up, however, so she
+goes better than ever, and I can take you to the police station in jig
+time. Want to come, Andy?"
+
+This was too much for the bully. He knew that Tom would have a clear
+case against him, and he did not dare answer. Instead he shuffled over
+to where his wheel lay, picked it up, and rode slowly off.
+
+"Good riddance," murmured Tom. He looked about, and saw that he was near
+a house, in the rear of which was a good-sized barn. "Guess I'll ask
+if I can leave the Butterfly there," he murmured, and, ringing the
+doorbell, he was greeted by a man.
+
+"I'll pay you if you'll let me store my machine in the barn a little
+while, until I go into the city, and return," spoke the lad.
+
+"Indeed, you're welcome to leave it there without pay," was the answer.
+"I'm interested in airships, and, I'll consider it a favor if you'll let
+me look yours over while it's here."
+
+Tom readily agreed, and a few minutes later he had caught a trolley
+going into the city. He was soon in one of the largest jewelry stores of
+Chester.
+
+"I'd like to get an expert opinion as to whether or not those stones are
+diamonds," spoke Tom, to the polite clerk who came up to wait on him,
+and our hero handed over the two gems which Mr. Jenks had given him.
+"I'm willing to pay for the appraisement, of course," the young inventor
+added, as he saw the clerk looking rather doubtfully at him, for Tom had
+on a rough suit, which he always donned when he flew in his monoplane.
+
+"I'll turn them over to our Mr. Porter, a gem expert," said the clerk.
+"Please be seated."
+
+The young man disappeared into a private office with the stones, and Tom
+waited. He wondered if he was going to have his trouble for his pains.
+Presently two elderly gentlemen came from the little room, on the glass
+door of which appeared the word "Diamonds."
+
+"Who brought these stones in?" asked one of the men, evidently the
+proprietor, from the deference paid him by the clerk. The latter
+motioned to Tom.
+
+"Will you kindly step inside here?" requested the elderly man. When the
+door was closed, Tom found himself in a room which was mostly taken up
+with a bench for the display of precious stones, a few chairs, and some
+lights arranged peculiarly; while various scales and instruments stood
+on a table.
+
+"You wished an opinion on--on these?" queried the proprietor of the
+place. Tom noticed at once that the word "diamonds" was not used.
+
+"I wanted to find out if they were of any value," he said. "Are they
+diamonds?"
+
+"Would you mind stating where you got them?" asked the other of the two
+men.
+
+"Is that necessary?" inquired the lad. "I came by them in a legitimate
+manner, if that's what you mean, and I can satisfy you on that point.
+I am willing to pay for any information you may give me as to their
+value."
+
+"Oh, it isn't that," the proprietor hastened to assure him. "But these
+are diamonds of such a peculiar kind, so perfect and without a flaw,
+that I wondered from what part of the world they came."
+
+"Then they are diamonds?" asked Tom, eagerly.
+
+"The finest I have ever tested!" declared the other man, evidently Mr.
+Porter, the gem expert. "They are a joy to look at, Mr. Roberts," he
+went on, turning to the proprietor. "If it is possible to get a supply
+of them you would be justified in asking half as much again as we charge
+for African or Indian diamonds. The Kimberly products are not to be
+compared to these," and he looked at the two stones in his hand--the one
+cut, and sparkling brilliantly, the other in a rough state.
+
+"Do you care to state where these diamonds came from?" asked Mr.
+Roberts, looking critically at Tom.
+
+"I had rather not," answered the lad. "It is enough for me to know that
+they are diamonds. How much is your charge?"
+
+"Nothing," was the unexpected answer. "We are very glad to have had the
+opportunity of seeing such stones. Is there any chance of getting any
+more?"
+
+"Perhaps," answered Tom, as he accepted the gems which the expert held
+out to him.
+
+"Then might we speak for a supply?" went on Mr. Roberts, eagerly. "We
+will pay you the full market price."
+
+"What is the value of these stones?" asked Tom.
+
+Mr. Roberts looked at his gem expert.
+
+"It is difficult to say," was the answer of the man who had handed Tom
+the gems. "They are so far superior to the usual run of diamonds, that
+I feel justified in saying that the cut one would bring fifteen hundred
+dollars, anywhere. In fact, I would offer that for it. The other is
+larger, though what it would lose in cutting would be hard to say. I
+should say it was worth two thousand dollars as it is now."
+
+"Thirty-five hundred dollars for these two stones!" exclaimed Tom.
+
+"They are worth every cent of it," declared Mr. Roberts. "Do you want to
+sell?"
+
+Tom shook his head. He could scarcely believe the good news. Mr. Jenks
+had told the truth. Now the young inventor could go with him to seek the
+diamond makers.
+
+"Can you get any more of these?" went on Mr. Roberts.
+
+"I think so--that is I don't know--I am going to try," answered the lad.
+
+"Then if you succeed I wish you would sell us some," fairly begged the
+proprietor of the store.
+
+"I will," promised Tom, but he little knew what lay before him, or
+perhaps he would not have made that promise. He thanked the diamond
+merchant for his kindness, and arranged to have the cut stone set in a
+pin for Miss Nestor. The uncut gem Tom took away with him.
+
+Thinking of many things, and wondering how best to start in his airship
+Red Cloud for the mysterious Phantom Mountain, Tom hurried back to where
+he had left the monoplane, wheeled it out, and was soon soaring through
+the air toward Shopton.
+
+"I think I'll go with Mr. Jenks," he decided, as he prepared for a
+landing in the open space near his aeroplane shed. "It will be a
+risky trip, perhaps, but I've taken risks before. When Mr. Jenks comes
+to-night I'll tell him I'll help him to get his rights, and discover the
+secret of the diamond makers."
+
+As Tom was wheeling the Butterfly into the shed, Eradicate came out to
+help him.
+
+"Dere's a gen'man here to see yo', Massa Tom," said the colored man.
+
+"Who is it?"
+
+"I dunno. He keep askin' ef yo' de lad what done bust up Earthquake
+Island, an' send lightnin' flashes up to de sky, an' all sech questions
+laik dat."
+
+"It isn't Mr. Damon; is it, Rad? He hasn't been around in some time."
+
+"No, Massa Tom, it ain't him. I knows dat blessin' man good an' proper.
+I jest wish he'd bless mah mule Boomerang some day, an' take some oh
+de temper out ob him. No, sah, it ain't Massa Damon. De gen'man's in de
+airship shed waitin' fo' you."
+
+"In the airship shed! No strangers are allowed in there, Rad."
+
+"I knows it, Massa Tom, but he done persisted his se'f inter it, an'
+he wouldn't come out when I told him; an' your pa an' Mr. Jackson ain't
+home."
+
+"I'll see about this," exclaimed Tom, striding to the large shed, where
+the Red Cloud was kept. As he entered it he saw a man looking over the
+wonderful craft.
+
+"Did you want to see me?" asked Tom, sharply, for he did not like
+strangers prowling around.
+
+"I did, and I apologize for entering here, but I am interested in
+airships, and I thought you might want to hire a pilot. I am in need
+of employment, and I have had considerable to do with balloons and
+aeroplanes, but never with an airship like this, which combines the two
+features. Do you wish to hire any one."
+
+"No, I don't!" replied Tom, sharply, for he did not like the looks of
+the man.
+
+"I was told that you did," was the rather surprising answer.
+
+"Who told you?"
+
+The man looked all around the shed, before replying, as if fearful of
+being overheard. Then, stepping close to Tom, he whispered:
+
+"Mr. Jenks told me!"
+
+"Mr. Jenks?" Tom could not conceal his astonishment.
+
+"Yes. Mr. Barcoe Jenks. But I did not come here to merely ask you for
+employment. I would like to hire out to you, but the real object of my
+visit was to say this to you."
+
+The man approached still closer to Tom, and, in a lower voice, and one
+that could scarcely be heard, he fairly hissed:
+
+"Don't go with Barcoe Jenks to seek the diamond makers!"
+
+Then, before Tom could put out a hand to detain him, had the lad so
+wished, the man turned suddenly, and fairly ran from the shed.
+
+
+
+
+CHAPTER VI--MR. DAMON IS ON HAND
+
+
+The young inventor stood almost spellbound for a few moments. Then
+recovering himself he made a dash for the door through which the
+mysterious man had disappeared. Tom saw him sprinting down the road, and
+was half-minded to take after him, but a cooler thought warned him that
+he had better not.
+
+"He may be one of those men who are on Mr. Jenks' trail," reasoned Tom,
+in which case it might not be altogether safe to attempt to stop him,
+and make him explain. Or he may be a lunatic, and in that case it
+wouldn't be altogether healthy to interfere with him.
+
+"I'll just let him go, and tell Mr. Jenks about him when he comes
+to-night. But I must warn Rad never to let him in here again. He might
+damage the airship."
+
+Calling to the colored man, Tom pointed to the stranger, who was almost
+out of sight down the road, and said earnestly:
+
+"Rad, do you see that fellow?"
+
+"I sho do, Massa Tom, but I sorter has t' strain my eyes t' do it. He's
+goin' laik my mule Boomerang does when he's comm' home t' dinnah."
+
+"That's right, Rad. Well, never let that man set foot inside our fence
+again! If he comes, and I'm home, call me. If I'm away, call dad or Mr.
+Jackson, and if you're here alone, drive him away, somehow."
+
+"I will, Massa Tom!" exclaimed the colored man, earnestly, "an' if I
+can't do it alone, I'll get Boomerang t' help. Once let dat ar' mule
+git his heels on a pusson, an' dat pusson ain't goin' t' come bodderin'
+around any mo'--that is, not right away."
+
+"I believe you, Rad. Well, keep a lookout for him, and don't let him
+in," and with that Tom entered the house to think over matters. They
+were beginning to assume an aspect he did not altogether like. Not that
+Tom was afraid of danger, but he preferred to meet it in the open, and
+the warning, or threat, of the mysterious man disquieted him.
+
+When Mr. Swift came home, a little later, his son told him of the
+midnight interview with Mr. Jenks, for, up to this time, the aged
+inventor was unaware of it, and Tom also gave an account of the
+diamonds, speaking of their value.
+
+"And do you propose to go to Phantom Mountain, in search of the makers
+of these gems, Tom?" asked Mr. Swift.
+
+"I had about decided to do so, dad."
+
+"And you're going in the Red Cloud?'
+
+"Yes."
+
+"Who are going with you?"
+
+"Well, Mr. Jenks will go, of course, and I've no doubt but that if I
+mention the prospective trip to Mr. Damon, that he'll bless his skating
+cap, or something like that, and come along."
+
+"I suppose so, Tom, and I'd like to have you take him. But I think
+you'll need some one else."
+
+"Because, from what you have told me, you are going out to a dangerous
+part of the country, and you may have to deal with unscrupulous men.
+Three of you are hardly enough to cope with them. You ought to have at
+least another member of your party. If I was not busy on my invention of
+a new wireless motor I would go along, but I can't leave. You might take
+Mr. Jackson."
+
+"No, you need him here to help you, dad."
+
+"How about Eradicate?"
+
+Tom smiled.
+
+"Rad would get homesick for his mule Boomerang, and I'd have to bring
+him back just when we'd found the diamonds," replied the young inventor.
+"No, we'll have to think of some one else. I'll ask Mr. Damon, and then
+I'll consider matters further. I expect to see Mr. Jenks to-night, and
+he may have some one in mind."
+
+"Perhaps that will be a good plan. Well, Tom, I trust you will take good
+care of yourself, and not run into unnecessary danger. Is the Red Cloud
+in good shape for the voyage?"
+
+"It needs looking over. I'm going to get right at it."
+
+"It's a pretty indefinite sort of a quest you're going on, Tom, my son.
+How do you expect to find Phantom Mountain?"
+
+"Well, it's going to be quite a task. In the first place we'll head for
+Leadville, Colorado, and then we'll go to Indian Ridge and make some
+inquiries. We may get on the track of the place that way. If we don't,
+why I'll take the airship up as high as is necessary and sort of
+prospect until we see that big cliff that's shaped like a head. That
+will give us something to go by."
+
+"Well, do the best you can. If you can discover the secret of making
+diamonds it will be a valuable one."
+
+"I guess it will, dad; and Mr. Jenks is entitled to know it, for he paid
+his good money to that end. He has promised to go halves with me, as
+payment for the use of the airship, and I must say the two diamonds he
+gave me last night have proved very valuable."
+
+"Two diamonds, Tom? You only showed me one, an uncut gem;" and Mr. Swift
+looked at his son.
+
+"Oh, the other--er--the other is--I left it with a jeweler," and Tom
+blushed a trifle, as he thought of the present he contemplated making to
+Mary Nestor.
+
+That afternoon, as Tom was out in the shed of the Red Cloud looking over
+the airship, to see what would be necessary to do to it in order to get
+it in shape for a long trip, he heard voices outside.
+
+"Yes--yes, I know the way in perfectly well," he caught. "You needn't
+bother to come, my good fellow. Just step this way, and I'll show you
+something worth seeing."
+
+"I wonder if it's that mysterious man coming back?" thought Tom. He
+dropped the tool he was using, and hurried to the door. As he approached
+it he heard the voice continue.
+
+"Why bless my shoe laces, Mr. Parker! You'll see a wonderful airship, I
+promise you. Wonderful! Bless my hatband, but I hope Tom is here!"
+
+"Mr. Damon!" exclaimed our hero, as he recognized the tones of his
+eccentric friend. "But who is with him?"
+
+A moment later he caught sight of the gentleman who was always blessing
+himself, or something. Behind him stood another man, whose features Tom
+could not see plainly.
+
+"Hello, Tom Swift!" called Mr. Damon. "Looking over the Red Cloud, eh?
+Does that mean you're off on another trip?"
+
+"I guess it does," answered the lad.
+
+"Where to this time? if I may ask."
+
+"I'm thinking of going off to the mountains to find a band of men
+engaged in making diamonds," replied Tom.
+
+"Making diamonds! Bless my finger ring! Making diamonds! A trip to the
+mountains! Bless my disposition! but do you know I'd like to go with
+you!"
+
+"I was thinking of asking you, Mr. Damon."
+
+"Were you? Bless my heart, I'm glad you thought of me. You don't by any
+possible chance want another person; do you?"
+
+"We were thinking of having four in the party, Mr. Damon," and Tom
+wondered who was with his eccentric friend.
+
+"Then bless my election ticket! This is the very chance for you, Mr.
+Parker!" cried Mr. Damon. "Will you go with us? It will be just what you
+need," and Mr. Damon stepped aside, revealing to Tom the features of Mr.
+Ralph Parker, the scientist who had correctly predicted the destruction
+of Earthquake Island.
+
+
+
+
+CHAPTER VII--MR. PARKER PREDICTS
+
+
+Tom Swift was a most generous lad, but when he saw that Mr. Damon had
+with him Mr. Parker, the gloomy scientist, who seemed to take delight in
+predicting disasters, our hero's spirits were not exactly of the best.
+He would have much preferred not to take Mr. Parker on the quest for the
+diamond makers, but, since Mr. Damon had mentioned it, he did not see
+how he could very well refuse.
+
+"But perhaps he won't care to go," thought Tom.
+
+He was undeceived a moment later, however, for the scientist remarked:
+
+I am very glad to meet you once more, Mr. Swift. I have scarcely thanked
+you enough for what you did for us in erecting your wireless station on
+Earthquake Island, which, as you recall, I predicted would sink into
+the sea. It did, I am glad to say, not because I like to see islands
+destroyed, but because science has been vindicated. Now I have just
+heard you remark that you are about to set off to the mountains in
+search of some men who are making diamonds. I need hardly state that
+this is utterly useless, for no diamonds, commercially valuable, can be
+made by men. But the trip may be valuable in that it will permit me to
+demonstrate some scientific facts.
+
+"Therefore, if you will permit me, I will be very glad to accompany you
+and Mr. Damon. I shall be delighted, in short, and I can start as soon
+as you are ready."
+
+"There's no hope for it!" thought Tom, dismally. "I suppose he'll wake
+up every morning, and predict that before night the world will come to
+an end, or he'll prophesy that the airship will blow up, and vanish,
+when about seven miles above the clouds. Well, there's no way out of it,
+so here goes."
+
+Thereupon Tom welcomed the scientist as cordially as he could, and
+invited him to form one of the party that would set off in the airship
+to search for Phantom Mountain.
+
+"Bless my jewelry box!" exclaimed Mr. Damon, when this formality was
+over. "Tell me more about it, Tom."
+
+Which our hero did, stating the need of maintaining secrecy on account
+of the danger to Mr. Jenks. Mr. Damon and Mr. Parker both agreed to say
+nothing about the matter, and then the scientist became much interested
+in the Red Cloud, which he closely examined. He even complimented Tom on
+the skill shown in making it, and, contrary to our hero's expectation,
+did not predict that it would blow up the next time it was used.
+
+"How did you happen to arrive just at this time, Mr. Damon?" asked Tom.
+
+"It was partly due to Mr. Parker," was the answer. "I had not seen him
+since we were rescued from the island, until a few days ago he called
+on me at my home. I happened to mention that you lived near here, and
+suggested that he might like to see some of your inventions. He agreed,
+and we came over in my auto. And now, bless my liver-pin! I find you
+about to start off on another trip."
+
+"And have you fully decided to go with me?" asked Tom. "There may be
+danger, and I don't like the way that mysterious man behaved."
+
+"Oh, bless my revolver!" cried Mr. Damon. "I'm used to danger by this
+time. Of course I'm going, and so is Mr. Parker. Do you know," and the
+man, who was always blessing something, came closer to the lad, and
+whispered: "Do you know, Tom, Mr. Parker is a very peculiar individual."
+
+"I'm sure of it," answered the young inventor, looking at the gentleman
+in question, who was then inside the airship cabin.
+
+"But he's all right, even if he is predicting unpleasant things," went
+on Mr. Damon. "I think we'll get better acquainted with him after a
+bit."
+
+"I hope so," agreed Tom, but he did not realize then how close his
+companionship with Mr. Parker was to be, nor what dangers they were to
+share later.
+
+The friends talked at considerable length of the prospective trip, and
+Tom, by this time, had ascertained what needed to be done to the airship
+to get it in shape to travel. It would take about a week, and, in the
+meanwhile, Mr. Damon would go home and get his affairs in order for
+the voyage. Tom's father was introduced to Mr. Parker, and, the former,
+finding that the scientist held some views in common with him, invited
+the gloomy predictor to remain at the Swift home until the Red Cloud was
+ready to sail. Tom could not repress a groan at this, but he decided he
+would have to make the best of it.
+
+Mr. Damon left for home that afternoon, promising to be on hand at the
+time set to start for Phantom Mountain.
+
+Tom was up waiting for Mr. Jenks at twelve o'clock that night. Shortly
+after the hour he saw a dark figure steal into the orchard. At first he
+feared lest it might be one of the spies who were, he was now convinced,
+on the trail of the man who was seeking to discover the secret of the
+diamond makers. But a whistle, which came to the lad's ear a moment
+later (that being a signal Mr. Jenks had agreed to sound), told Tom that
+it was none other than the visitor he expected.
+
+"All right, Mr. Jenks, I'm here," called Tom, cautiously. "Come over
+this way," and he went out from the shadow of the house, where he had
+been waiting, and met the men. "We'll go into my private work-shop," the
+youth added, leading the way.
+
+"Have you decided to go with me?" asked Mr. Jenks, in an anxious
+whisper. "Did you find the diamonds to be real ones?"
+
+"I did; and I'm going," spoke Tom.
+
+"Good! That relieves my mind. But we are still in danger. I was followed
+by my shadower to-day, and only succeeded in shaking him off just before
+coming here. I don't believe he knows what I am about to do."
+
+"Oh, yes he does," said Tom.
+
+"He does? How?"
+
+"Because he was here, and warned me against you!"
+
+"You don't mean it! Well, they are getting desperate! We must be on our
+guard. What sort of a man was he?"
+
+Tom described the fellow, and Mr. Jenks stated that this tallied with
+the appearance of the person who had been shadowing him.
+
+"But we'll fool them yet!" cried Tom, who had now fully entered into the
+spirit of the affair. "If they can follow us in the Red Cloud they're
+welcome to. I think we'll get ahead of them."
+
+He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed that
+it would add to the strength of the party to take these two gentlemen
+along.
+
+"Though I can't say I care so much for Mr. Parker," he added. "But now
+as to ways and means. When can we start?"
+
+Thereupon he and Tom talked over details in the seclusion of the little
+office, and arranged to leave Shopton in about a week. In the meanwhile
+the airship would be overhauled, stocked with supplies and provisions,
+and be made ready for a swift dash to the mountains.
+
+"And now I must be going," said Mr. Jenks. "I have a great deal to do
+before I can start on this trip, and I hope I am not prevented by any of
+those men who seem to be trailing me."
+
+"How could they prevent you?" Tom wanted to know.
+
+"Oh, there are any number of ways," was the answer. "But I'm glad you
+found that my diamonds were real. We'll soon have plenty, if all goes
+well."
+
+As Mr. Jenks left the shop, he started back, in some alarm.
+
+"What's the matter?" asked Tom.
+
+"Over there--I thought I saw a figure sneaking along under the
+trees--that man--perhaps--"
+
+"That's Eradicate, our colored helper," replied Tom, with a laugh.
+"I posted him there to see that no strangers came into the orchard.
+Everything all right, Rad?" he asked, raising his voice.
+
+"Yais, sah, Massa Tom. Nobody been around yeah this night."
+
+"That's good. You can go to bed now," and Eradicate, yawning loudly,
+went to his shack. A little later Tom sought his own room, Mr. Jenks
+having hurried off to town, where he was boarding.
+
+The next few days saw Tom busily engaged on the airship, making some
+changes and a few repairs that were needed. His father, Eradicate and
+Mr. Jackson helped him. As for Mr. Parker, the scientist, he went about
+the place, being much interested in the various machines which Tom or
+Mr. Swift had patented.
+
+At other times the scientist would stroll about the extensive grounds,
+making what he said were "observations." One afternoon Tom saw him,
+apparently much excited, kneeling down back of a shed, with his ear to
+the ground.
+
+"What is the matter?" asked the lad, thinking perhaps Mr. Parker might
+be ill.
+
+"Have you ever had any earthquakes here, Tom Swift?" asked the
+scientist, quietly.
+
+"Earthquakes? No. We had enough of them on the island."
+
+"And you are going to have one here, in about two minutes!" cried Mr.
+Parker. "I predict that this place will be shaken by a tremendous shock
+very soon. We had all better get away from the vicinity of buildings."
+
+"What makes you think there will be an earthquake?" asked Tom.
+
+"Because I can hear the rumbling beneath the ground at this very minute.
+It is increasing in volume, showing that the tremors are working this
+way. There will soon be a great subterranean upheaval! Listen for
+yourself."
+
+Tom cast himself down on the grass. Placing his ear close to the ground
+he did hear a series of dull thuds. He arose, not a little alarmed.
+There had never been any earthquakes in Shopton, yet he had great
+respect for Mr. Parker's scientific attainments.
+
+Just then Eradicate Sampson came along. He saw Tom and Mr. Parker lying
+flat on the ground, and surprise showed on his honest, black face.
+
+"Fo' de land sakes!" cried Eradicate. "What am de mattah now, Massa
+Tom?"
+
+"Earthquake coming," answered Tom, briefly. "Better get away from the
+buildings, Rad. They might fall!" Tom's face showed the alarm he felt.
+What would happen to all of his valuable machines--to the Red Cloud?
+
+"Earthquake?" murmured Eradicate, and he, too, cast himself down to
+listen. A moment later he arose with a laugh.
+
+"What's the matter?" cried Tom.
+
+"Why, dat ain't no earthquake!" declared the colored man.
+
+"No. Then perhaps you know what it is," said Mr. Parker, somewhat
+sharply.
+
+"Course I knows what it am," answered Eradicate, with dignity. "Dat
+noise am my mule Boomerang, kickin' in his stable, on account oh me not
+feedin' him yet. Dat's what it am. I'se gwine right now t' gib him his
+oats, and den yo' see dat de noise stop. Boomerang allers kick dat way
+when he's hungry. I show yo'!"
+
+And, sure enough, when Eradicate had gone to the mule's stable,
+which was near where Mr. Parker had heard the mysterious sounds, they
+immediately ceased.
+
+"Dat mule was all de earthquake dere was around here," said the colored
+man as he came out.
+
+Mr. Parker walked away, saying nothing, and Tom did not make any
+comments--just then.
+
+
+
+
+CHAPTER VIII--OFF FOR THE WEST
+
+
+It was a great relief to Tom, to find that there was no danger from an
+earth tremor. Now that he had made up his mind to go in search of
+the diamond makers, he wanted nothing to interfere with it. Lest the
+feelings of Mr. Parker might be hurt by the mistake he had made, the
+young inventor cautioned Eradicate not to say anything more about the
+matter.
+
+"'Deed an' I won't," the colored man promised. "I'se only too glad dere
+wa'n't no earthquake, dat's what I is."
+
+As for Mr. Parker, he did not appear much put out by his error in
+predicting.
+
+"I am sure that what I heard was a tremor, due to some distant
+earthquake shock," he said. "The mule's kicking was only a coincidence."
+
+And Tom let him have his way about it. The week was drawing to a close,
+and the Red Cloud was nearly in shape for the voyage. At almost the
+last minute Tom found that he needed some electrical apparatus for the
+airship, and as he had to go to Chester for it, he decided he would make
+the trip in his monoplane, and, while in the city, would also get the
+diamond pin he was having made for Mary Nestor.
+
+He started off early one morning, in the swift little craft Butterfly,
+and soon had reached Chester. The diamond brooch was ready for him.
+
+"It is one of the most beautiful stones we have ever set," the diamond
+merchant told him. "Don't forget, if you find any more, Mr. Swift, to
+let us have a chance to bid on them."
+
+"I may," Tom promised, rather indefinitely. Then, having purchased his
+electrical supplies, he made a quick trip to Shopton, stopping on the
+way to call on Miss Nestor.
+
+"Why Tom, I'm delighted to see you!" cried the girl, blushing prettily.
+"Did you come for some apple turnovers?" and she laughed, as she
+referred to a call Tom had once paid, when a new cook had been engaged,
+and when the pastry formed a feature of the meal.
+
+"No turnovers this time," said the young inventor. "I came to wish you
+many happy returns of the day."
+
+"Oh, you remembered my birthday! How nice of you!"
+
+"And here is something else," added our hero, rather awkwardly, as he
+handed her the diamond pin.
+
+"Oh, Tom! This for me! Oh, it's too lovely--it's far too much!"
+
+"It isn't half enough!" he declared, warmly.
+
+"Oh, what a large diamond!" Mary cried as she saw the sparkling stone.
+"I never saw one so large and beautiful!"
+
+"It's just as easy to make them large as small," explained Tom.
+
+"Make them?" she looked the surprise she felt.
+
+"Yes, I'm about to start for the place where diamonds are made."
+
+"Oh, Tom! But isn't it dangerous? I mean won't you have to go to some
+far country--like Africa--to get to where diamonds are made?"
+
+"Well, we are going on quite a trip, but not as far as that. And as
+for the danger--well, we'll have to take what comes," and he told her
+something of the proposed quest.
+
+"Oh, it sounds--sounds scary!" Mary exclaimed, when she had heard of Mr.
+Jenks' experience. "Do be careful, Tom!"
+
+"I will," he promised, and, somehow he was glad that she had cautioned
+him thus--and in such tones as she had used. For Mary Nestor was a girl
+that any young chap would have been glad to have manifest an interest in
+him.
+
+"Well, I guess I'll have to say good-by," spoke Tom, at length. "We
+expect to start in a couple of days, and I may not get another chance to
+see you."
+
+"Oh, I--I hope you come back safely," faltered Mary, and then she held
+out her hand, and Tom--well, it's none of our affair what Tom did
+after that, except to say that he hurried out, fairly jumped into his
+monoplane, and completed the trip home.
+
+As the Red Cloud has been fully described in the volume entitled "Tom
+Swift and His Airship," we will not go into details about it now.
+Sufficient to say that it was a combination of a biplane and dirigible
+balloon. It could be used either as one or the other, and the gas-bag
+feature was of value when the wind was too great to allow the use of the
+planes, or when the motive power, for some reason stopped. In that event
+the airship could remain suspended far above the clouds if necessary.
+There was provision for manufacturing the gas on board.
+
+The Red Cloud was fitted up to accommodate about ten persons, though it
+was seldom that this number was carried. Two persons could successfully
+operate the machinery. There were sleeping berths, and in the main cabin
+a sitting-room, a dining-room, and a kitchen. There was also the motor
+compartment, and a steering tower, from which the engines could be
+controlled.
+
+It was in this craft that the seekers after the diamond makers proposed
+undertaking the trip. Mr. Damon came on from his home in Waterfield
+about two days before the date set to leave, and Mr. Jenks, had, three
+days before this, taken up his abode at the Swift home. Mr. Parker, as
+has been stated, was already there, and he had put in his time making
+a number of scientific observations, though he had made no more
+predictions.
+
+Nothing more had been seen of the mysterious man who had warned Tom,
+and the young inventor and Mr. Jenks began to hope that they had thrown
+their enemies off the track.
+
+"Though I don't imagine they'll give up altogether," said Mr. Jenks.
+"They're too desperate for that. We'll have trouble with them yet."
+
+"Well, it can't be helped," decided Tom. "We'll try and be ready for it,
+when it comes," and then, dismissing the matter from his mind, he busied
+himself about the airship.
+
+The food and supplies had all been put aboard, and they expected to
+start the next morning. In order to make sure that any stones which they
+might succeed in getting from the diamond makers were real gems, a set
+of testing apparatus was taken along. Mr. Parker had had some experience
+in this line, and, in spite of the fact that he might make direful
+predictions, Tom was rather glad, after all, that the scientist was
+going to accompany them.
+
+"But what is worrying me," said Mr. Damon, "is what we are going to do
+after we get to Phantom Mountain. What are your plans, Mr. Jenks? Will
+you go in, and demand your share of the diamond-making business?"
+
+"I have a right to it, as I invested a large sum in it, and I am
+entitled to more than a half-share. But, of course, I can't say what
+I'll do until I get there. We may have to act very secretly."
+
+"I'm inclined to think we will," said Tom. "My plan would be to gain
+access to the cave, if possible, and watch them at work. We might be
+able to discover the secret of making diamonds, and, after all, that's
+what you want, isn't it, Mr. Jenks?"
+
+"Yes, I paid my money for the secret, and I ought to have it. If I can
+get it quietly, so much the better. If not, I'll fight for my rights!"
+and he looked very determined.
+
+"Bless my powder horn!" cried Mr. Damon. "That's the way to talk! And
+so we're to go cruising about in the air, looking for a mountain shaped
+like a man's head."
+
+"That's it," agreed Mr. Jenks, "and when we find it we will be near
+Phantom Mountain, and the diamond makers."
+
+The final details were completed that night. The last of the supplies
+had been put aboard, the larder was well stocked, the diamond testing
+apparatus was stored safely away, and all that remained was for the
+adventurers to board the Red Cloud in the morning, and soar away.
+
+That night Tom was uneasy. Several times he got up, and looked toward
+the shed where the airship was stored. He could not rid himself of
+the idea that the men to whose interest it was that the diamond-making
+secret remain undiscovered, might attempt to wreck the airship before
+the start. Consequently both Eradicate Sampson and Engineer Jackson were
+on guard. Tom looked from his window, to the shed where the Red Cloud
+was housed. He saw nothing to cause him any uneasiness.
+
+"I guess I'm just nervous," he mused. "But, all the same, I'll be glad
+when we've started."
+
+They were all up early the next morning, Mr. Damon beginning the day by
+blessing the sunrise, and many other things that struck his fancy.
+The airship was wheeled out of the shed, and Tom gave her a final
+inspection.
+
+"It's all right," he declared. "All aboard!"
+
+"Now, do be careful," begged Mr. Swift. "Don't take too many chances,
+Tom."
+
+"I'll not."
+
+The adventurers were in the forward part of the ship, and Tom had taken
+his place at the wheels and levers in the pilot house. As he was about
+to start the motor he looked toward the road, and saw a horse and
+carriage. In the vehicle was a girlish figure, at the sight of which Tom
+blushed and smiled. He waved his hand.
+
+"I came to wish you good luck!" cried Mary Nestor, for it was she in the
+carriage.
+
+"Thanks!" cried Tom, leaning from the window of the pilot house. "It was
+good of you to get up so early."
+
+"Oh. I'm always up early," she informed him.
+
+"Look out that the motor doesn't scare your horse," Tom warned her.
+
+"Old Dobbin doesn't mind anything," was her answer. "I'll see that he
+doesn't run away with me, as long as you're not on earth to rescue me.
+Good-by, Tom!"
+
+"Good-by!" he called, and then he pulled the lever that set in motion
+the motor, and whirled the great propellers about. They whizzed around
+with a roar, and the Red Cloud, shivering and trembling with the
+vibration, rose in the air like some great bird.
+
+"We're off for the West and Phantom Mountain!" called Tom to his
+companions.
+
+As the airship soared upward, Eradicate Sampson ran forward from where
+he had been standing near his mule Boomerang. He waved his hands, and
+shouted something.
+
+"Bless my hatband! What does he want?" asked Mr. Damon, watching him
+curiously.
+
+"It sounds as if he were calling to us to come back," spoke Mr. Parker.
+
+"It's too late now," decided Tom. "Maybe he forgot to tell us good-by,"
+but, he felt a vague wonder at Eradicate's odd motions; for the colored
+man was pointing toward the stern of the airship, as if there was
+something wrong there. But the Red Cloud soared on.
+
+
+
+
+CHAPTER IX--A WARNING BY WIRELESS
+
+
+Rapidly the airship ascended, and, when it was high over the town of
+Shopton, Tom headed the craft due west. Looking down he tried to descry
+Mary Nestor, in her carriage, but the trees were in the way, their
+interlocking branches hiding the girl. Tom did see crowds of other
+persons, though, thronging the streets of Shopton, for, though the young
+inventor had made many flights, there was always a novelty about them,
+that brought out the curious.
+
+"A good start, Tom Swift," complimented Mr. Parker. "Is it always as
+easy as this?"
+
+"Starting always is," was the answer, "though, as the Irishman said,
+coming down isn't sometimes quite so comfortable."
+
+"Bless my gizzard! That's so," cried the eccentric Mr. Damon. "Can we
+vol-plane to earth in the Red Cloud, Tom?"
+
+"Yes, but not as easily as in the Butterfly. However I hope we will not
+have to. Now, Mr. Damon, if you will just take charge of the steering
+apparatus for a minute, I want to go aft."
+
+"What for?"
+
+"I wish to see if everything is all right. I can't imagine why Eradicate
+was making those queer motions."
+
+Mr. Damon, who knew how to operate the Red Cloud, was soon guiding her
+on the course, while Tom made his way to the rear compartments, through
+the motor room, where the stores of supplies and food were kept. He made
+a careful examination, looking from an after window, and even going out
+on a small, open platform, but could discover nothing wrong.
+
+"I guess Rad was just capering about without any special object," mused
+Tom, but it was not long after this that they learned to their dismay,
+that the colored man had had a method in his madness.
+
+On his way back through the motor room Tom looked to the machinery,
+and adjusted some of the auxiliary oil feeders. The various pieces of
+apparatus were working well, though the engine had not yet been speeded
+up to its limit. Tom wanted it to "warm-up" first.
+
+"Everything all right?" asked Mr. Damon, as Tom rejoined them in the
+pilot house, which was just forward of the living room in the main
+cabin.
+
+"Yes, I can't imagine what made Rad act that way. But I'll set the
+automatic steering gear now, Mr. Damon, and then you will be relieved."
+
+Mr. Jenks was gazing off toward the west--to where he hoped to discover
+the secret of Phantom Mountain.
+
+"How do you like it?" asked Tom.
+
+"It's great," replied the diamond man. "I've never been in an airship
+before, and it's different than what I expected; but it's great! It's
+the only craft that will serve our purpose among the towering mountain
+peaks, where the diamond makers are hidden. I hope we can find them."
+
+In a little while the Red Cloud was skimming along at faster speed,
+guided by the automatic rudders, so that no one was needed in the pilot
+house, since there was no danger of collisions. Airships are not quite
+numerous enough for that, yet, though they may soon become so.
+
+Tom and the others devoted several hours to arranging their staterooms
+and bunks, and getting their clothing stowed away, and when this was
+done Mr. Parker and Mr. Jenks sat gazing off into space.
+
+"It's hard to realize that we are really in an airship," observed the
+diamond man. "At first I thought I would be frightened, but I'm not a
+bit. It doesn't seem as if anything could happen."
+
+"Something is likely to happen soon," said Mr. Parker, suddenly, as he
+gazed at some weather instruments on the cabin wall.
+
+"Bless my soul! Don't say that!" cried Mr. Damon. "What is it?"
+
+"I think, from my observations, that we will soon have a hurricane,"
+said the scientific man. "There is every indication of it;" and he
+seemed quite delighted at the prospect of his prediction coming true.
+
+"A hurricane!" cried Mr. Damon. "I hope it isn't like the one that blew
+us to Earthquake Island."
+
+"Oh, I think there will be no danger," spoke Tom. "If it comes on to
+blow we will ascend or descend out of the path of the storm. This craft
+is not like the ill-fated Whizzer. I can more easily handle the Red
+Cloud; even in a bad storm."
+
+"I'm glad to hear that," remarked Mr. Jenks. "It would be too bad to be
+wrecked before we got to Phantom Mountain."
+
+"Well, I predict that we will have a bad storm," insisted Mr. Parker,
+and Tom could not help wishing that the scientist would keep his gloomy
+forebodings to himself.
+
+However the storm had not developed up to noon, when Tom, with Mr.
+Damon's help, served a fine meal in the dining-room. In the afternoon
+the speed of the ship was increased, and by night they had covered
+several hundred miles. Through the darkness the Red Cloud kept on,
+making good time. Tom got up, occasionally, to look to the machinery,
+but it was all automatically controlled, and an alarm bell would sound
+in his stateroom when anything went wrong.
+
+"Bless my napkin!" exclaimed Mr. Damon the next morning, as they sat
+down to a breakfast of fruit, ham and eggs and fragrant coffee, "this is
+living as well as in a hotel, and yet we are--how far are we above the
+earth, Tom?" he asked, turning to the young inventor.
+
+"About two miles now. I just sent her up, as I thought I detected that
+storm Mr. Parker spoke of."
+
+"I told you it would come," declared the scientist, and there was a
+small hurricane below them that morning, but only the lower edge of it
+caught the Red Cloud, and when Tom sent her up still higher she found a
+comparatively quiet zone, where she slid along at good speed.
+
+That afternoon Tom busied himself about some wires and a number of
+complicated pieces of apparatus which were in one corner of the main
+cabin.
+
+"What are you doing now?" asked Mr. Jenks, who had been talking with Mr.
+Parker, and showing that scientist some of the manufactured diamonds.
+
+"Getting our wireless apparatus in shape," answered the lad. "I should
+have done it before, but I had so much to do that I couldn't get at it.
+I'm going to send off some messages. Dad will want to know how we are
+doing."
+
+As he worked away, he also made up his mind to send another message, in
+care of his father, for there was a receiving station in the Swift home.
+And to whom this message was addressed Tom did not say, but we fancy
+some of our readers can guess.
+
+Finally, after several hours of work, the wireless was in shape to send
+and receive messages. Tom pulled over the lever, and a crackling sound
+was heard, as the electricity leaped from the transmitters into space.
+Then he clamped the receiver on his ear.
+
+"All ready," he announced. "Has anybody any messages they wish sent?"
+For, with the courtesy of a true host he was ready to serve his guests
+before he forwarded his own wireless notes.
+
+"Just tell my wife that I'm enjoying myself," requested Mr. Damon.
+"Bless my footstool! But this is great! We're off the earth yet,
+connected with it."
+
+Mr. Jenks had no one to whom he wanted to send any word, but Mr. Parker
+wish to wire to a fellow scientist the result of some observations made
+in the upper air.
+
+Tom noted all the messages down, and then, when all was in readiness he
+began to call his home station. He knew that either his father or Mr.
+Jackson, the engineer, could receive the wireless.
+
+But, no sooner had the young inventor sent off the first few dots and
+dashes representing "S. I."--his home station call--than he started and
+a look of surprise came over his face.
+
+"They're calling us!" he exclaimed.
+
+"Who is?" asked Mr. Jenks.
+
+"My house--my father. He--he's been trying to get us ever since we
+started, but I didn't have the wireless in shape to receive messages.
+Oh, I hope it's not too late!"
+
+"Too late! Bless my soul, too late for what?" gasped Mr. Damon, somewhat
+alarmed by Tom's manner.
+
+The lad did not answer at once. He was intently listening to a series
+of dots and dashes that clicked in the telephone receiver clamped to his
+left ear. On his face there was a look of worriment.
+
+"Father has just sent me a message," he said. "It's a warning flashed
+through space! He's been trying to get it to me since yesterday!"
+
+"What is it?" asked Mr. Jenks, rising from his seat.
+
+"The mysterious man is aboard the airship--hidden away!" cried Tom.
+"That's what Eradicate was trying to call to our attention as we started
+off. Eradicate saw his face at a rear window, and tried to warn us! The
+mysterious man is a stowaway on board!"
+
+
+
+
+CHAPTER X--DROPPING THE STOWAWAY
+
+
+Tom's excited announcement startled Mr. Damon and the others as much as
+if the young inventor had informed them that the airship had exploded
+and was about to dash with them to the earth. The men leaped to their
+feet, and stared at the lad.
+
+"A stowaway on board!" cried Mr. Damon. "Bless my soul! How did he--"
+
+"Are you sure that message is straight?" asked Mr. Jenks. "Did Eradicate
+see the man?"
+
+"He says he did," answered Tom. "The man is hidden away on board
+now--probably among the stores and supplies."
+
+"Bless my tomato sauce!" exploded Mr. Damon. "I hope he doesn't eat them
+all up!"
+
+"We must get him out at once!" declared Mr. Jenks.
+
+"I knew something would happen on this voyage," came from Mr. Parker. "I
+predicted it from the first!"
+
+Tom thought considerable, but he did not answer the scientist just
+then. Another communication was coming to him by wireless. He listened
+intently.
+
+"Father says," the lad told his companions "that Eradicate only had
+a glimpse of the man at the last moment. He was looking from the rear
+storeroom window--he's the same man who called on me that time--Rad
+remembers him very well."
+
+"Bless my shoes! What's to be done?" inquired Mr. Damon, looking around
+helplessly.
+
+"We must get him out, that's all," decided Mr. Jenks; with vigor. "Get
+him out and drop him overboard!"
+
+"Drop him overboard!" cried Mr. Parker, in horror.
+
+"Not exactly, but get rid of him," proceeded the diamond seeker. "That
+man is one of my enemies. He has been sent by the band of diamond makers
+hidden among the mountains, to spy on me, and, if possible, prevent me
+from seeking to discover their secret. He tried to work on Tom's Swift's
+fears, and frighten him from using his airship on this quest. Then, when
+he failed, the man must have sneaked into the shed, and hidden himself
+in the ship. We must get rid of him, or he may wreck the Red Cloud!"
+
+"That's so!" cried Tom. "We must try to capture him. I think we had
+better--" the lad paused, and again listened to the wireless message.
+"Father says Eradicate saw the man have a gun, so we must be careful,"
+the young inventor translated the dots and dashes.
+
+"Bless my powder horn!" exploded Mr. Damon.
+
+"We shall have to proceed cautiously then," spoke Mr. Jenks. "If he is
+like any others in the gang he is a desperate man."
+
+"Better sneak up on him then, if we can," proposed Mr. Parker. "There
+are enough of us to cope with one man, even if he is armed. You have
+weapons aboard, haven't you?" he inquired of Tom.
+
+"Yes," was the hesitating answer, "but I don't want to use them if I
+can help it. Not only because of the danger, and a dislike of shedding
+blood, but because a stray bullet might pierce the gas bag and damage
+the ship."
+
+"That's so," agreed Mr. Jenks. "Well, I guess if we go at it the right
+way we can capture him without any shooting. But we must talk more
+quietly--we ought to have whispered--he may have heard us."
+
+"I don't think so," replied Tom. "The storeroom is far enough off so
+that he couldn't hear us. Besides, the motor makes such a racket that
+he couldn't distinguish what we were talking about, even if he heard our
+voices. So, unless he heard the wireless working, and suspects something
+from that, he probably doesn't know that we are aware of his presence
+aboard."
+
+"But why do you think he has remained quiet all this while, Tom?" asked
+Mr. Damon.
+
+"Probably he wants to wait until the ship is farther out west,"
+suggested Mr. Jenks. "Then he will be nearer his friends, and can get
+help, if he needs it."
+
+"And do you really believe he would destroy the Red Cloud?" asked Mr.
+Parker.
+
+"I think that all he is waiting for is a favorable chance," declared
+the diamond seeker. "He would destroy the craft, and us too, if he could
+prevent us from discovering the secret of Phantom Mountain, I believe."
+
+"Then we must get ahead of him," decided Tom, quietly. "I have just
+flashed to dad a message, telling him that we will heed his warning. Now
+to capture the stowaway!"
+
+"And while we're about it, give him a good scare when we do get him,"
+suggested Mr. Jenks.
+
+"How?" asked Tom.
+
+"Threaten to drop him overboard. Perhaps that will make him tell how
+he happened to get in our ship, and what are the plans of the gang of
+diamond makers. We may get valuable information that way."
+
+"I don't believe you can scare such fellows much," was Tom's opinion,
+but it was agreed to try.
+
+"How are you going to capture him?" asked Mr. Parker. "If he has a gun
+it won't be any too easy to go in the storeroom, and drag him out."
+
+"We'll have to use a little strategy," decided Tom, and then they
+discussed several plans. The one finally adopted was that Tom and Mr.
+Damon should enter the storeroom, casually, as if in search of food to
+cook for supper. They would discuss various dishes, and Mr. Damon was to
+express a preference for something in the food line, the box containing
+which, was well back in the room. This would give the two a chance
+to penetrate to the far end of the apartment, without arousing the
+suspicions of the hidden man, who, doubtless, would be listening to the
+conversation.
+
+"And as soon as we get sight of him, you and I will jump right at him,
+Mr. Damon," said Tom. "Jump before he has a chance to use his gun. Mr.
+Jenks and Mr. Parker will be waiting outside the room, to catch him if
+he gets away from us. I'll have some ropes ready, and we'll tie him up,
+and--well, we'll decide later what to do with him."
+
+"All right. I'm ready as soon as you are, Tom," said the eccentric man.
+"Come ahead."
+
+They went softly to the storeroom, and listened at the door. There was
+no sound heard save that made by the machinery.
+
+"I wonder if he's really here?" whispered Mr. Damon.
+
+"We'll soon find out," answered Tom. "Let's go in."
+
+They entered, and, in pursuance of their plan, Tom and his friend talked
+of various foods.
+
+"I think I'd like some of that canned lobster, with French dressing on,"
+spoke the eccentric man.
+
+"That's away in the back end of the room," said Tom, in a loud voice.
+"It's under a lot of boxes."
+
+"Then I'll help you get it out! Bless my frying pan! but I am very fond
+of lobster!" exclaimed Mr. Damon, in as natural tones as was possible
+under the circumstances.
+
+He and Tom moved cautiously back among the boxes and barrels. They were
+glancing about with eager eyes. Tom switched on an electric light, and,
+the instant he did so, he was aware of a movement in a little space
+formed by one box which was placed on top, of two others. The lad saw a
+dark figure moving, as if to get farther out of sight.
+
+"I've got him!" cried Tom, making a dive for the shadow.
+
+A moment later the young inventor was bowled over, as a dark figure
+leaped over his head.
+
+"Catch him, Mr. Damon!" he cried.
+
+"Bless my hatband! I--I--" Mr. Damon's voice ended in a grunt. He, too,
+had been knocked down by the fleeing man.
+
+"Look out, Mr. Jenks!" cried Tom, to warn those on guard at the door of
+the storeroom.
+
+There was the report of a gun, some excited shouts, and when Tom could
+scramble to his feet, and rush out, he beheld Mr. Parker calmly sitting
+on a struggling man, while Mr. Jenks held a gun, that was still smoking.
+
+"We caught him!" cried the scientist.
+
+"Anybody hurt?" asked Tom, anxiously.
+
+"No, I knocked up his gun as he fired," explained Mr. Jenks. "Where are
+the ropes, Tom?"
+
+The cords were produced and the man, who had now ceased to struggle,
+was tightly bound. He uttered not a word, but he smiled grimly when Mr.
+Damon remarked:
+
+"I guess I'll go back in the storeroom, Tom, and see how much food he
+ate."
+
+"Oh, I guess he didn't take much," declared the lad. "He wasn't there
+long enough."
+
+"Well, Farley Munson, so it's you, is it?" asked Mr. Jenks, as he
+surveyed the prisoner.
+
+"Do you know him?" asked Tom, in some surprise.
+
+"He was in with the diamond makers," said Mr. Jenks. "He was one of
+those who took me to the secret cave. But it will be the last time he
+ever goes there. How high up are we, Tom?"
+
+"About two miles. Why?"
+
+"I guess that will be far enough to let him fall," went on the diamond
+seeker. "Come on, Mr. Damon, help me throw him overboard!"
+
+"You--you're not going to throw me over--with the airship two miles
+high; are you?" gasped the man.
+
+"Will you tell us what we want to know, if we don't?" asked Mr. Jenks.
+
+"What do you want to know?"
+
+"How you got aboard, and what your object was in coming."
+
+"That's easy enough. I had been hanging around the shed for several
+days, watching a chance to get in. Finally I saw it, when that colored
+man went to feed his mule, and I slipped in, and hid in the airship. The
+stores were all in then, and I stowed myself away among the boxes. I had
+food and water, so I didn't touch any of yours," and he looked at Mr.
+Damon, who seemed much relieved.
+
+"And what was your object?" demanded Mr. Jenks.
+
+"I wanted to prevent you from going to Phantom Mountain."
+
+"How?"
+
+"By destroying the airship if need be. But I hoped to accomplish it by
+other means. I would have stopped at nothing, though, to prevent you.
+You must keep away from there!"
+
+"And if we refuse?" asked Tom.
+
+"Then you'll have to take what comes!"
+
+"But not from you!" exclaimed Mr. Jenks. "We're going to get rid of
+you."
+
+The man's face showed the alarm he felt.
+
+"Oh, don't worry," said Mr. Jenks, quickly, "we're not going to toss you
+overboard. We're not as desperate as your crowd. But we're going to
+get rid of you, and then go on before you can send any word to your
+confederates. We'll put you off in the most lonesome spot we can find,
+and I guess you'll be some time getting back to civilization. By that
+time we'll have the secret of the diamonds."
+
+"You never will!" declared the man, firmly. And he would say nothing
+more, though by threats and promises Mr. Jenks tried to get from him
+something about the men in with him, and where the cave of the diamonds
+was located.
+
+Heavily bound with ropes the man was locked in a small closet, to be
+kept there until a favorable spot was reached for letting him go. Mr.
+Jenks' plan, of dropping him down in some place where he would have
+difficulty in sending on word to his confederates was considered a good
+one.
+
+Three days later, in crossing over a lonely region, near the Nebraska
+National Forest, Farley Munson, which was one of the names the spy went
+by, was dropped off the airship, when it was sent down to within a few
+feet of the earth.
+
+"It will take you some time to get to a telegraph office," said Mr.
+Jenks, as a package of food, and a flask of water was tossed down to the
+stowaway. He shook his fist at those in the airship, and shouted after
+them:
+
+"You'll never discover the secret of Phantom Mountain!"
+
+"Yes, we will," declared Tom, as he sent the Red Cloud high into the air
+again.
+
+
+
+CHAPTER XI--A WEARY SEARCH
+
+
+During the three days when the stowaway had been kept a prisoner, the
+Red Cloud had made good time on her western trip. She was now about two
+hundred and fifty miles from Leadville, Colorado, and Tom knew he could
+accomplish that distance in a short time. It was necessary, therefore,
+since they were so close to the place where the real search would begin,
+to make some more definite plans.
+
+"We will need to replenish our supply of gasoline," said Tom, shortly
+after the stowaway had been dropped, and when the young inventor had
+made a general inspection of the airship.
+
+"Is it all gone?" inquired Mr. Damon.
+
+"Not all, but we will soon be in the wildest part of the Rocky
+Mountains, and gasoline is difficult to procure there. So I want to fill
+all our reserve tanks. But I would rather do that before we get far into
+Colorado."
+
+"Why?" inquired Mr. Parker.
+
+"Because airships are not so common but what the appearance of one
+attracts attention. Ours is sure to be talked about, and commented on.
+In that case, in spite of our precaution in putting Munson off in this
+lonely place, word of the Red Cloud being in the vicinity of Leadville
+may reach the diamond makers, and put them on their guard. We want to
+take them unawares if we can."
+
+"That's so," agreed Mr. Jenks. "We had better get our gasoline at the
+first stopping place, then, and proceed with our search. Our first
+object ought to be to look for the landmark--the head of stone. Then we
+can begin to prospect about a bit."
+
+"My idea, exactly," declared Tom. "Well, then, I'll go down at the
+first place we cross, where we can get gasoline, and then we'll be in a
+position to hover in the air for a long time, without descending."
+
+The airship kept on her way, traveling slowly the remainder of that day,
+and at dusk, when there was less chance of big crowds seeing them, the
+Red Cloud was sent down on the outskirts of a large village. Tom and Mr.
+Damon went to a supply store, and arranged to have a sufficient quantity
+of the gasoline taken out to the airship. It was delivered after dark,
+and little talk was occasioned by the few who were aware of the presence
+of the craft. Then, once more, they went aloft, and Tom sent several
+wireless messages to Shopton, including one to Miss Nestor.
+
+"Please tell my wife that I am well, and that I have a good appetite,"
+said Mr. Damon.
+
+Mr. Parker also sent a message to a scientific friend of his, stating
+that he made some observations among the mountains, of the region in
+which the airship then was, and that the indications were that a great
+landslide would soon take place.
+
+"That won't worry us," spoke Tom, "for we'll be far above it."
+
+"I hope we will be near enough to enable me to observe it, and make
+some scientific notes," came from Mr. Parker. "I am positive that one
+of these mountain peaks that we saw to-day will disappear in a landslide
+within a few days. I have an instrument somewhat like the one that
+records earthquakes, and it has been acting strangely of late."
+
+Tom wondered what enjoyment Mr. Parker got out of life, when he was
+always looking for some calamity to happen, but the scientist seemed
+to take as much pleasure in his gloomy forebodings now, as he had on
+Earthquake Island.
+
+They reached the vicinity of Leadville the next day, but took care to
+keep high above the city, so that the airship could not be observed.
+With powerful glasses they examined the mountainous country, looking for
+the little settlement of Indian Ridge.
+
+"There it is!" exclaimed Mr. Jenks, just as dusk was settling down. "I
+can make out the hotel I stopped at. Now we can really begin our search.
+The next thing is to find the stone head, and then, I think, I will have
+my bearings."
+
+"We'll begin the hunt for that landmark in the morning," said Tom.
+
+High in the air hovered the Red Cloud. At that distance above the earth
+she must have looked like some great bird, and the adventurers thought
+it unlikely that any one in the vicinity of Leadville would observe
+them.
+
+The quest for the great mountain peak, that looked like a stone head,
+was under way. Back and forth sailed the airship. Sometimes she was
+enveloped in fog, and no sight could be had of the earth below. At
+other times there were rain storms, which likewise prevented a view. Mr.
+Parker was on the lookout for his predicted mountain landslide, but it
+did not occur, and he was much disappointed.
+
+"It's queer I can't pick out that landmark," said Mr. Jenks after two
+days of weary searching, when their eyes were strained from long peering
+through telescopes. "I'm sure it was around Indian Ridge, yet we've
+covered almost all the ground in this neighborhood, and I haven't had a
+glimpse of it."
+
+"Perhaps it was destroyed in a landslide, or some cataclysm of nature,"
+suggested Mr. Parker. "That is very possible."
+
+"If that's the case we're going to have a hard time to locate the cave
+of the diamond makers," answered Mr. Jenks, "but I hope it isn't so."
+
+They continued the search for another day, and then Tom, as they sat
+in the comfortable cabin of the airship that night, hovering almost
+motionless (for the motor had been shut down) made a proposition.
+
+"Why not descend in some secluded place," he suggested, "and wander
+around on foot, making inquiries of the miners. They may know where the
+stone head is, or they may even know about Phantom Mountain."
+
+"Good idea," spoke Mr. Jenks. "We'll do it."
+
+Accordingly, the next morning, the Red Cloud was lowered in a good but
+lonely landing place, and securely moored. It was in a valley, well
+screened from observation, and the craft was not likely to be seen,
+but, to guard against any damage being done to it by passing hunters or
+miners, Mr. Parker and Mr. Damon agreed to remain on guard in it, while
+Tom and Mr. Jenks spent a day or two traveling around, making inquiries.
+
+The young inventor and his companion proceeded on foot to a small
+settlement, where they hired horses on which to make their way about.
+They were to be gone two days, and in that time they hoped to get on the
+right trail.
+
+
+
+
+CHAPTER XII--THE GREAT STONE HEAD
+
+
+It was a wild and desolate country in which Tom Swift and Mr. Jenks
+were traveling. Villages were far apart, and they were at best but
+small settlements. In their journeys from place to place they met few
+travelers.
+
+But of these few they made cautious inquiries as to the location
+of Phantom Mountain, or the landmark known as the great stone head.
+Prospectors, miners and hunters, whom they asked, shook their heads.
+
+"I've heard of Phantom Mountain," said one grizzled miner, "but I
+couldn't say where it is. Maybe it's only a fish story--the place may
+not even exist."
+
+"Oh, it does, for I've been there!" exclaimed Mr. Jenks.
+
+"Then why don't you go back to it?" asked the miner.
+
+"Because I can't locate it again," was the reply.
+
+"Humph! Mighty queer if you've seen a place once, and can't get to it
+again," and the man looked as if he thought there was something strange
+about Tom and his companion. Mr. Jenks did not want to say that he had
+been taken to the mountain blindfolded, for that would have caused too
+much talk.
+
+"I think if we spent to-night in a place where the miners congregate,
+listened to their talk, and put a few casual questions to them, more as
+if we were only asking out of idle curiosity, we might learn something,"
+suggested Tom.
+
+"Very well, we'll try that scheme."
+
+Accordingly, after they had left the suspicious miner the two proceeded
+to a small milling town, not far from Indian Ridge. There they engaged
+rooms for the night at the only hotel, and, after supper they sat around
+the combined dance hall and gambling place.
+
+There were wild, rough scenes, which were distasteful to Tom, and to Mr.
+Jenks, but they felt that this was their only chance to get on the right
+trail, and so they stayed. As strangers in a western mining settlement
+they were made roughly welcome, and in response to their inquiries about
+the country, they were told many tales, some of which were evidently
+gotten up for the benefit of the "tenderfeet."
+
+"Is there a place around here called Phantom Mountain?" asked Tom, at
+length, as quietly as he could.
+
+"Never heard of it, stranger," replied a miner who had done most of the
+talking. "I never heard of it, and what Bill Slatterly don't know ain't
+worth knowin'. I'm Bill Slatterly," he added, lest there be some doubt
+on that score.
+
+"Isn't there some sort of a landmark around here shaped like a great
+stone head?" went on Tom, after some unimportant questions. "Seems to me
+I've heard of that."
+
+"Nary a one," answered Mr. Slatterly. "No stone heads, and no Phantom
+Mountains--nary a one.
+
+"Who says there ain't no Phantom Mountains?" demanded an elderly miner,
+who had been dozing in one corner of the room, but who was awakened by
+Slatterly's loud voice. "Who says so?"
+
+"I do," answered the one who claimed to know everything.
+
+"Then you're wrong!" Tom's heart commenced beating faster than usual.
+
+"Do you mean to say you've seen Phantom Mountain, Jed Nugg?" demanded
+Slatterly.
+
+"No, I ain't exactly seen it, an' I don't want to, but there is such
+a place, about sixty mile from here. Folks says it's haunted, and them
+sort of places I steer clear from."
+
+"Can you tell me about it?" asked Mr. Jenks, eagerly. "I am interested
+in such things."
+
+"I can't tell you much about it," was the reply, "and I wouldn't git too
+interested, if I was you. It might not be healthy. All I know is that
+one time my partner and I were in hard luck. We got grub-staked, and
+went out prospectin'. We strayed into a wild part of the country about
+sixty mile from here, and one night we camped on a mountain--a wild,
+desolate place it was too."
+
+The miner stopped, and began leisurely filling his pipe.
+
+"Well?" asked Tom, trying not to let his voice sound too eager.
+
+"Well, that was Phantom Mountain."
+
+The miner seemed to have finished his story.
+
+"Is that all?" asked Mr. Jenks. "How did you know it was Phantom
+Mountain?"
+
+"'Cause we seen the ghost--my partner and I--that's why!" exclaimed the
+man, puffing on his pipe. "As I said, we was campin' there, and 'long
+about midnight we seen somethin' tall and white, and all shimmerin',
+with a sort of yellow fire, slidin' down the side of the mountain. It
+made straight for our camp."
+
+"Huh! Guess you run, didn't you, Jed?" asked Bill Slatterly.
+
+"Course we did. You'd a run too, if you seen a ghost comm' at you, an'
+firin' a gun."
+
+"Ghosts can't fire guns!" declared Bill. "I guess you dreamed it, Jed."
+
+"Ghosts can't fire guns, eh? That's all you know about it. This one did,
+and to prove I didn't dream it, there was a bullet hole in my hat next
+mornin'. I could prove it, too, only I ain't got that hat any more. But
+that was Phantom Mountain, strangers, an' my advice to you is to keep
+away from it. I was on it but I didn't exactly see it, 'cause it was
+dark at the time."
+
+"Was it near a peak that looked like a stone head?" asked Tom.
+
+"It were, stranger, but I didn't take much notice of it. Me and my
+partner got out of them diggin's next day, and I never went back. I
+ain't never said much about this place, but it's called Phantom Mountain
+all right, and I ain't the only one that's seen a ghost there. Other
+grub-stakers has had the same experience."
+
+"Why ain't I never heard about it?" demanded Bill, suspiciously.
+
+"'Cause as why you're allers so busy talkin' that you don't never listen
+to nothin' I reckon," was Jed's answer, amid laughter.
+
+"Can you tell us what trail to take to get there?" asked Tom, of the
+miner.
+
+"Yes, it's called the old silver trail, and you strike it by goin' to a
+place called Black Gulch, about forty mile from here. Then it's twenty
+mile farther on. But take my advice and don't go."
+
+"Can it be reached by way of Indian Ridge?" asked Mr. Jenks, wondering
+how he had been taken to the cave of the diamond makers. He did not
+remember Black Gulch.
+
+"Yes, you can git there by Indian Ridge way, but it's more dangerous.
+You're likely to lose your way, for that's a trail that's seldom
+traveled." Mr. Jenks thought that, perhaps, was the reason the gang had
+taken him that way. "It's easier to get to the stone head and Phantom
+Mountain by Black Gulch, but it ain't healthy to go there, strangers,
+take my advice on that," concluded the miner, as he prepared to go to
+sleep again.
+
+Tom could scarcely contain the exultation he felt. At last, it seemed,
+they were on the trail. He motioned to Mr. Jenks, and they slipped
+quietly from the place, just as another dance was beginning.
+
+"Now for Black Gulch!" cried Tom. "We must hurry back to the airship,
+and tell the good news.
+
+"It's too late to-night," decided Mr. Jenks, and so they waited until
+morning, when they made an early start.
+
+They found Mr. Damon and Mr. Parker anxiously awaiting their return. Mr.
+Damon blessed so many things that he was nearly out of breath, and Mr.
+Parker related something of the observations he had made.
+
+"I think I have discovered traces of a dormant volcano," he said. "I am
+in hopes that it will have an eruption while we are here."
+
+"I'm not," spoke Tom, decidedly. "We'll start for Black Gulch as soon as
+possible."
+
+The airship once more rose in the air, and, following the directions
+the miner had given him, Tom pointed his craft for the depression in the
+mountains which had been given the name Black Gulch. It was reached in
+a short time, and then, making a turn up a long valley the airship
+proceeded at reduced speed.
+
+"We ought to see that stone head soon now," spoke Tom, as he peered from
+the windows of the pilot house.
+
+"It's queer we didn't notice it when we were up in the air," remarked
+Mr. Jenks. "We've been over this place before, I'm sure of it."
+
+The next moment Mr. Damon uttered a cry. "Bless my watch-chain!" he
+exclaimed. "Look at that!"
+
+He pointed off to the left. There, jutting out from the side of a steep
+mountain peak was a mass of stone--black stone--which, as the airship
+slowly approached, took the form and shape of a giant's head.
+
+"That's it! That's it!" cried Tom. "The great stone head!"
+
+"And now for Phantom Mountain and the diamonds!" shouted Mr. Jenks, as
+Tom let the airship slowly settle to the bottom of the valley.
+
+
+
+
+CHAPTER XIII--ON PHANTOM MOUNTAIN
+
+
+Out from the Red Cloud piled Tom and the others. They made a rush for
+the irregular mass of rock which bore so strong a resemblance to the
+head of some gigantic man.
+
+"That's the one! That's the thing I saw when they were taking me along
+here blindfolded!" exclaimed Mr. Jenks. "I'm sure we're on the right
+trail, now!"
+
+"But what gets me, though," remarked Mr. Damon, "is why we couldn't see
+that landmark when we were up in the air. We had a fine view, and ought
+to have been able to pick it out with the telescopes."
+
+The adventurers saw the reason a few seconds later. The image was
+visible only from one place, and that was directly looking up the
+valley. If one went too far to the right or left the head disappeared
+from view behind jutting crags, and it was impossible to see it from
+overhead, because the head was almost under a great spur of a mighty
+mountain.
+
+"We might have hunted for it a week in the airship, and been directly
+over it," said Tom, "and yet we would never have seen it."
+
+"Yes, but we never would have gotten here in such good shape if it
+hadn't been for your wonderful craft," declared Mr. Jenks. "It brought
+us here safely and quickly, and enabled us to elude the men who tried to
+keep us back. We're here in spite of them. If we had traveled by train
+they might have interfered with us in a dozen ways."
+
+"That's so," agreed Mr. Damon. "Well, now we're here, what's to be
+done? Which way do we start to reach the cave where the diamonds are
+manufactured, Mr. Jenks?"
+
+"That I can't say. As you know, I only had a momentary glimpse of this
+stone head as they were taking me along the trail. Then one of the men
+noticed that the bandage had slipped and he pulled it into place. So I
+really can't say which direction to take now, in order to discover the
+secret."
+
+"How long after you saw the head before you reached the cave?" asked
+Tom. "In that way we may be able to tell how far away it is."
+
+"Well, I should say it was about two or three hours after I saw the
+head, before we got to the halting place, and I was carried into the
+cave. That would make it several miles from here, for we went in a
+wagon."
+
+"Yes, and they might have driven in a round-about way, in order to
+deceive you," suggested Mr. Damon. "At best we have but a faint idea
+where the diamond cave is, but we must search for it; eh, Tom?"
+
+"Certainly. We'll start right in. And as the airship will be of but
+little service to us now, I suggest that we leave it in this valley.
+It is very much secluded, and no one will harm it, I think. We can then
+start off prospecting, for I have a large portable tent, and we can
+carry enough food with us, with what game we can shoot, to enable us to
+live. I have a regular camping outfit on board."
+
+"Fine!" cried Mr. Parker, "and that will give me a chance to make some
+observations among the mountains, and perhaps I can predict when a
+landslide, or an eruption of some dormant volcano, may occur."
+
+"Bless my stars!" cried Mr. Damon. "I don't wish you any bad luck, Mr.
+Parker, but I sincerely hope nothing of the sort happens! We had enough
+of that on Earthquake Island!"
+
+"One can not halt the forces of nature," said the scientist, solemnly.
+"There are many towering peaks around here which may contain old
+volcanoes. And I notice the presence of iron ore all about. This must be
+a wonderful place in a thunder and lightning storm."
+
+"Why?" asked Tom, curiously.
+
+"Because lightning would be powerfully attracted here by the presence
+of the metal. In fact there is evidence that many of the peaks have been
+struck by lightning," and the scientist showed curious, livid scars on
+the stone faces of the peaks within sight.
+
+"Then this is a good place to stay away from in a storm," observed Mr.
+Damon. "However, we won't worry about that now. If this is the landmark
+Mr. Jenks was searching for, then we must be in the vicinity of Phantom
+Mountain."
+
+"I think we are," declared the diamond seeker. "Probably it is within
+sight now, but there are so many peaks, and this is such a wild and
+desolate part of the country that we may have trouble in locating it."
+
+"We've got to make a beginning, anyhow," decided Tom, "and the sooner
+the better. Come, we'll make up our camping kits, and start out."
+
+It was something to know that they were on the right trail, and it was a
+relief to be able to busy oneself, and not be aimlessly searching for a
+mysterious landmark. They all felt this, and soon the airship was taken
+to a secluded part of the valley, where it was well hidden from sight in
+a grove of trees.
+
+Tom and Mr. Damon then served a good meal, and preparations were made
+to start on their search among the mountains--a search which they hoped
+would lead them to Phantom Mountain, and the cave of the diamond makers.
+
+The tent which would afford them shelter was in sections, and could
+be laced together. They carried food, compressed into small packages,
+coffee, a few cooking utensils; and each one had a gun, Tom carrying a
+combination rifle and shotgun, for game.
+
+"We can't live very high while we're on the trail," said the young
+inventor, "but it won't be much worse than it was on Earthquake Island.
+Are we all ready?"
+
+"I guess so," answered Mr. Damon. "How long are we going to be away?"
+
+"Until we find the diamond makers!" declared Tom, firmly.
+
+Shouldering their packs, the adventurers started off. Tom turned for a
+last look at his airship, dimly seen amid the trees. Would he ever come
+back to the Red Cloud? Would she be there when he did return? Would
+their quest be successful? These questions the lad asked himself, as he
+followed his companions along the rocky trail.
+
+"Perhaps we can find the road by which these men go in and out of the
+cave," suggested Mr. Damon, when they had gone on for several miles.
+
+"I fancy not," replied Mr. Jenks. "They probably take great pains to
+hide it. I think though, that our best plan will be to go here and
+there, looking for the entrance to the cave. I believe I would remember
+the place."
+
+"But why can't you follow the directions given by the miner who told you
+about Phantom Mountain?" asked Mr. Damon.
+
+"Because his talk was too indefinite," answered Mr. Jenks. "He was so
+frightened by seeing what he believed to be a ghost, that he didn't take
+much notice of the location of the place. All he knows is that Phantom
+Mountain is somewhere around here."
+
+"And we've got to hunt until we find it; is that the idea?" asked Mr.
+Parker.
+
+"Or until we see the phantom," added Tom, in a low voice.
+
+"Bless my topknot!" exclaimed Mr. Damon. "You don't mean to say you
+expect to see that ghost; do you Tom?"
+
+"Perhaps," answered the young inventor, and he did not add something
+else of which he was thinking. For Tom had a curious theory regarding
+the phantom.
+
+They tramped about the remainder of that day. Toward evening Tom shot
+some birds, which made a welcome addition to their supper. Then the tent
+was put together, some spruce and hemlock boughs were cut to make a soft
+bed, and on these, while the light of a campfire gleamed in on them, the
+adventurers slept.
+
+Their experience the following day was similar to the first. They saw no
+evidence of a large cave such as Mr. Jenks had described, nor were there
+any traces of men having gone back and forth among the mountains, as
+might have been expected of the diamond makers, for, as Mr. Jenks had
+said, they made frequent journeys to the settlement for food, and other
+supplies.
+
+"Well, I haven't begun to give up yet," announced Tom, on the third day,
+when their quest was still unsuccessful. "But I think we are making one
+mistake."
+
+"What is that?" inquired Mr. Jenks.
+
+"I think we should go up higher. In my opinion the cave is near the top
+of some peak; isn't it, Mr. Jenks?"
+
+"I have that impression, though, as you know, I never saw the outside of
+it. Still, it might not be a bad idea to ascend some of these peaks."
+
+Following this suggestion, they laid their trail more toward the sky,
+and that night found them encamped several thousand feet above the
+sea-level. It was quite cool, and the campfire was a big one about which
+they sat after supper, talking of many things.
+
+Tom did not sleep well that night. He tossed from side to side on the
+bed of boughs, and once or twice got up to replenish the fire, which had
+burned low. His companions were in deep slumber.
+
+"I wonder what time it is?" mused Tom, when he had been up the third
+time to throw wood on the blaze. "Must be near morning." He looked at
+his watch, and was somewhat startled to see that it was only a little
+after twelve. Somehow it seemed much later.
+
+As he was putting the timepiece back into his pocket the lad looked
+around at the dark and gloomy mountains, amid which they were encamped.
+As his gaze wandered toward the peak of the one on the side of which the
+tent was pitched, he gave a start of surprise.
+
+For, coming down a place where, that afternoon, Tom had noticed a sort
+of indefinite trail was a figure in white. A tall, waving figure, which
+swayed this way and that--a figure which halted and then came on again.
+
+"I wonder--I wonder if that can be a wisp of fog?" mused the young
+inventor. He rubbed his eyes, thinking it might be a swirling of the
+night mist or a defect of vision. Then, as he saw more plainly, he
+noticed the thing in white rushing toward him.
+
+"It's the phantom--the phantom!" cried Tom, aloud. "It's the thing the
+miner saw! We're on Phantom Mountain now!"
+
+
+
+
+CHAPTER XIV--WARNED BACK
+
+
+Tom's cries awakened the sleepers in the tent. Mr. Damon was the first
+to rush out.
+
+"Bless my nightcap, Tom!" he cried. "What is it? What has happened? Are
+we attacked by a mountain lion?"
+
+For answer the young inventor pointed up the mountain, to where, in the
+dim light from a crescent moon, there stood boldly revealed, the figure
+in white.
+
+"Bless--bless my very existence!" cried the odd man. "What is it, Tom?"
+
+"The phantom," was the quiet answer. "Watch it, and see what it does."
+
+By this time Mr. Jenks and Mr. Parker had joined Tom and Mr. Damon.
+The four diamond seekers stood gazing at the apparition. And, as they
+looked, the thing in white, seemingly too tall for any human being, slid
+slowly forward, with a gliding motion. Then it raised its long, white
+arms, and waved them threateningly at the adventurers.
+
+"It's motioning us to go back," said Mr. Parker in an awed whisper. "It
+doesn't want us to go any farther."
+
+"Very likely," agreed Tom, coolly. "But we're not going to be frightened
+by anything like that; are we?"
+
+"Not much!" exclaimed Mr. Jenks. "I expected this. A ghost can't drive
+me back from getting my rights from those scoundrels!"
+
+"Suppose it uses a revolver to back up its demand?" asked the scientist.
+
+"Wait until it does," answered Mr. Jenks. But the figure in white
+evidently had no such intentions. It came on a little distance
+farther, still waving the long arms threateningly, and then it suddenly
+disappeared, seeming to dissolve in the misty shadows of the night.
+
+"Bless my suspenders!" cried Mr. Damon. "That's a very strange
+proceeding! Very strange! What do you make of it, Tom?"
+
+"It is evidently some man dressed up in a sheet," declared Mr. Jenks. "I
+expected as much."
+
+"The work of those diamond makers; do you think?" continued Mr. Damon.
+
+"I believe so," answered Tom, slowly, for he was trying to think it out.
+"I believe they are the cause of the phantom, though I don't know that
+it's a man dressed in a sheet."
+
+"Why isn't it?" demanded Mr. Jenks.
+
+"Because it was too tall for a man, unless he's a giant."
+
+"He may have been on stilts," suggested Mr. Parker.
+
+"No man on stilts could walk along that way," declared Tom, confidently.
+"He glided along too easily. I am inclined to think it may be some sort
+of a light."
+
+"A light?" queried Mr. Damon.
+
+"Yes, the diamond makers may be hidden in some small cave near here, and
+they may have some sort of a magic lantern or a similar arrangement, for
+throwing a shadow picture. They could arrange it to move as they liked,
+and could cause it to disappear at will. That, I think, is the ghost we
+have just seen."
+
+"But the diamond makers have only been in this mountain recently,"
+objected Mr. Jenks, "and the phantom was here before them. In fact, that
+was what gave the place its name."
+
+"That may be," admitted the lad. "There are many places that have the
+name of being haunted, but no one ever sees the ghost. It is always some
+one else, who has heard of some one who has seen it. That may have been
+the case here. I grant that this place may have been called 'Phantom
+Mountain' for a number of years, due to the superstitious tales of
+miners. The diamond makers came along, found the conditions just right
+for their work, and adopted the ghost, so to speak. As there wasn't any
+real spirit they made one, and they use it to scare people away. I think
+that's what we've just seen, though I may be wrong in my theory as to
+what the phantom is."
+
+"Well, it's gone now, at any rate," said Mr. Jenks, "and I think we'd
+better get back inside the tent. It's cold out here."
+
+"Aren't some of us going to stand guard?" demanded Mr. Damon.
+
+"What for?" asked Mr. Jenks.
+
+"Why--er--bless my key-ring! Suppose that ghost takes a notion to come
+down here, and use his gun, as he did on the miners?"
+
+"I don't believe that will happen," remarked Tom. "The diamond makers,
+if the white thing had anything to do with them, have given us a
+warning, and I think they'll at least wait until morning to see how we
+heed it."
+
+"We aren't going to heed it!" burst out Mr. Jenks. "I'm going to go
+right ahead and find that cave where they make diamonds!"
+
+"And we're with you!" exclaimed Tom. "We'll have a good fire going the
+rest of the night, and that may keep intruders away. In the morning
+we'll begin our search, and we'll go up the trail where we saw the white
+figure."
+
+A big pile of wood had been collected for the fire, and Tom now piled
+some logs and branches on the blaze. It would last for some time now,
+and the adventurers, still talking of the "ghost" went back into the
+tent. It was over an hour before they all got to sleep again, and Mr.
+Jenks and Mr. Damon took turns in getting up once or twice during the
+remainder of the night to replenish the fire.
+
+Morning dawned without anything further having occurred to disturb them,
+and, after a hearty breakfast, to which Tom added some fish he caught in
+a nearby mountain stream, they set off up the trail on Phantom Mountain.
+
+They had left their tent standing, as they proposed making that spot
+their headquarters until they located the cave they were seeking. What
+their course would be after that would depend on the circumstances.
+
+If they had expected to have an easy task locating the cavern in which
+Mr. Jenks had seen diamonds made, the adventurers were disappointed. All
+that day they tramped up and down the mountain, looking for some secret
+entrance, but none was disclosed. The higher they went up the great
+peak, the fainter became the trail, until, at length it vanished
+completely.
+
+But this was not to be wondered at, since it was on solid rock, in which
+no footsteps would leave an impression.
+
+"They never brought you up here in a wagon, Mr. Jenks," decided Tom,
+when he saw how steep the place was.
+
+"I'm inclined to think so myself," admitted the diamond man. "They must
+have reached the cave from some other way. As a matter of fact, I walked
+some distance after getting out of the vehicle, before we got to the
+cavern. But, even at that, I don't believe we came this way."
+
+"Yet the phantom was here," persisted Tom, "and I'm convinced that the
+cave is in this neighborhood. It's up to us to find it!"
+
+But they searched the remainder of that day in vain, and as night was
+coming on, they made their way back to the camp. As Tom, who was in
+the lead, approached the tent, he saw something black fastened to the
+entrance.
+
+"Hello!" he cried. "Some one's been here. That wasn't on the tent when
+we left this morning."
+
+"What is it?" asked Mr. Damon.
+
+"A black piece of paper, written on with white ink," replied the lad. He
+was reading it, and, as he perused it a look of surprise came over his
+face.
+
+"Listen to this!" called Tom. "It's evidently from the diamond makers."
+
+Holding up the black paper, on which the white writing stood out in bold
+relief Tom read aloud:
+
+
+"Be warned in time! Go back before it is too late! You are near to
+death! Go back!"
+
+
+"Bless my shoelaces!" cried Mr. Damon. "This is getting serious."
+
+
+
+
+CHAPTER XV--THE LANDSLIDE
+
+
+Gathered about the young inventor, the three men looked at the warning.
+The writing was poor, and it was evident that an attempt had been made
+to disguise it. But there was no misspelling of words, and there were no
+rudely drawn daggers, or bloody hands or anything of that sort. In fact,
+it was a very business-like sort of warning.
+
+"Rather odd," commented Mr. Jenks. "Black paper and white ink."
+
+"White ink is easy enough to make," stated Mr. Parker. "I fancy they
+wanted it as conspicuous as possible."
+
+"Yes," agreed Tom, "and this warning, together with the antics of the
+thing in white last night, shows that they are aware of our presence
+here, and perhaps know who we are. We will have to be on our guard."
+
+"Do you think that fellow Munson, whom we left in the forest, could have
+gotten here and warned them?" asked Mr. Damon.
+
+"It's possible," admitted Tom, "but now let's see if the person who
+pinned this warning on our tent took any of our things."
+
+A hasty examination, however, showed that nothing had been disturbed,
+and Tom and Mr. Damon were soon getting supper ready, everyone talking,
+during the progress of the meal, about the events of the day, and the
+rather weird culmination of it.
+
+"Well, we haven't had a great deal of success--so far," admitted Tom, as
+they sat about the fire, in the fast gathering dusk. "I think, perhaps,
+we'd better try on the other side of the mountain to-morrow. We've
+explored this side pretty thoroughly."
+
+"Good idea," commented Mr. Jenks. "We'll do it, and move our camp. I
+only hope those fellows don't find our airship and destroy it. We'll
+have a hard time getting back to civilization again, if we have to walk
+all the way."
+
+This contingency caused Tom some uneasiness. He did not like to think
+that the unscrupulous men might damage the Red Cloud, that had been
+built only after hard labor. But he knew he could accomplish nothing by
+worrying, and he tried to dismiss the matter from his mind.
+
+They rather expected to see the thing in white again that night, but it
+did not appear, and morning came without anything having disturbed their
+heavy sleep, for they were tired from the day's tramp.
+
+It took them the greater part of the day to make a circuit of the base
+of Phantom Mountain in order to get to a place where a sort of trail led
+upward.
+
+"It's too late to do anything to-night," decided Tom, as they set up the
+tent. "We'll rest, and start the first thing in the morning."
+
+"And the ghost isn't likely to find us here," added Mr. Damon. "Where
+are you going, Mr. Parker?" he asked, as he saw the scientist tramping a
+little way up the side of the mountain.
+
+"I am going to make some observations," was the answer, and no one paid
+any more attention to him for some time. Supper was nearly ready when
+Mr. Parker returned. His face wore a rather serious air, and Mr. Damon,
+noting it, asked laughingly:
+
+"Well, did you discover any volcanoes, that may erupt during the night,
+and scare us to death?"
+
+"No," replied Mr. Parker, calmly, "but there is every indication that we
+will soon have a terrific electrical storm. From a high peak I caught a
+glimpse of one working this way across the mountains."
+
+"Then we'd better fasten the tent well down," called Tom. "We don't want
+it to blow away."
+
+"There will not be much danger from wind," was Mr. Parker's opinion.
+
+"From what then?" asked Mr. Jenks.
+
+"From the discharges of lightning among these mountain peaks, which
+contain so much iron ore. We will be in grave danger."
+
+The fact that the scientist had not always made correct predictions was
+not now considered by his hearers, and Tom and the two men gazed at Mr.
+Parker in some alarm.
+
+"Is there anything we can do to avoid it?" asked Mr. Jenks.
+
+"The only thing to do would be to leave the mountain," was the answer,
+"and, as the iron ore extends for miles, we can not get out of the
+danger zone before the storm will reach us. It will be here in less than
+half an hour."
+
+"Then we'd better have supper," remarked Tom, practically, "and get
+ready for it. Perhaps it may not be as bad as Mr. Parker fears."
+
+"It will be bad enough," declared the gloomy scientist, and he seemed to
+find pleasure in his announcement.
+
+The meal was soon over, and Tom busied himself in looking to the guy
+ropes of the tent, for he feared lest there might be wind with the
+storm. That it was coming was evident, for now low mutterings of thunder
+could be heard off toward the west.
+
+Black clouds rapidly obscured the heavens, and the sound of thunder
+increased. Fitful flashes of lightning could be seen forking across the
+sky in jagged chains of purple light.
+
+"It's going to be a heavy storm," Tom admitted to himself. "I hope
+lightning doesn't strike around here."
+
+The storm came on rapidly, but there was a curious quietness in the air
+that was more alarming than if a wind had blown. The campfire burned
+steadily, and there was a certain oppressiveness in the atmosphere.
+
+It was now quite dark, save when the fitful lightning flashes came,
+and they illuminated the scene brilliantly for a few seconds. Then, by
+contrast, it was blacker than ever.
+
+Suddenly, as Tom was gazing up toward the peak of Phantom Mountain, he
+saw something that caused him to cry out in alarm. He pointed upward,
+and whispered hoarsely:
+
+"The ghost again! There's our friend in white!"
+
+The others looked, and saw the same weird figure that had menaced them
+when they were encamped on the other side of the peak.
+
+"They must have followed us," said Mr. Jenks, in a low voice.
+
+Slowly the figure advanced, It waved the long white arms, as if in
+warning. At times it would be only dimly visible in the blackness, then,
+suddenly it would stand out in bold relief as a great flash of fire
+split the clouds.
+
+The thunder, meanwhile, had been growing louder and sharper, indicating
+the nearer approach of the storm. Each lightning flash was followed in a
+second or two, by a terrific clap. Still there was no wind nor rain, and
+the campfire burned steadily.
+
+All at once there was a crash as if the very mountain had split asunder,
+and the adventurers saw a great ball of purple-bluish fire shoot down,
+as if from some cloud, and strike against the side of the crag, not a
+hundred feet from where stood the ghostly figure in white.
+
+"That was a bad one," cried Mr. Damon, shouting so as to be heard above
+the echoes of the thunderclap.
+
+Almost as he spoke there came another explosion, even louder than the
+one preceding. A great ball of fire, pear shaped, leaped for the same
+spot in the mountain.
+
+"There's a mass of iron ore there!" yelled Mr. Parker. "The lightning is
+attracted to it!"
+
+His voice was swallowed up in the terrific crash that followed, and,
+as there came another flash of the celestial fire, the figure in
+white could be seen hurrying back up the mountain trail. Evidently the
+electrical storm, with lightning bolts discharging so close, was too
+much for the "ghost."
+
+In another instant it looked as if the whole place about where the
+diamond seekers stood, was a mass of fire. Great forked tongues of
+lightning leaped from the clouds, and seemed to lick the ground. There
+was a rattle and bang of thunder, like the firing of a battery of guns.
+Tom and the others felt themselves tingling all over, as if they had
+hold of an electrical battery, and there was a strong smell of sulphur
+in the air.
+
+"We are in the midst of the storm!" cried Mr. Parker. "We are standing
+on a mass of iron ore! Any minute may be our last!"
+
+But fate had not intended the adventurers for death by lightning. Almost
+as suddenly as it had begun, the discharge of the tongues of fire ceased
+in the immediate vicinity of our friends. They stood still--awed--not
+knowing what to do.
+
+Then, once more, came a terrific clap! A great mass of fire, like some
+red-hot ingot from a foundry, was hurled through the air, straight at
+the face of the mountain, and at the spot where the figure in white had
+stood but a few minutes before.
+
+Instantly the earth trembled, as it had at Earthquake Island, but it was
+not the same. It was over in a few seconds. Then, as the diamond seekers
+looked, they saw in the glare of a score of lightning flashes that
+followed the one great clap, the whole side of the mountain slip away,
+and go crashing into the valley below.
+
+"A landslide!" cried Mr. Parker. "That is the landslide which I
+predicted! The lightning bolt has split Phantom Mountain!"
+
+
+
+
+CHAPTER XVI--THE VAST CAVERN
+
+
+For a time the roiling, slipping, sliding and tumbling of the mass of
+earth and stones, down the side of the mountain, effectually drowned
+all other sounds. Even the thunder was stilled, and though Tom and his
+companions called to one another in terror, their voices could not rise
+above that terrific tumult.
+
+Finally, when they found that the direction of the slide was away from
+their tent, and that they were not likely to be engulfed, they grew more
+calm.
+
+Gradually the noise subsided. The great boulders had rolled to the
+bottom of the valley, and now only a mass of earth and stones was
+sliding down. Even this stopped in about five minutes, and, as though
+satisfied with what it had done, the electrical storm passed. Not a drop
+of rain had fallen.
+
+"Bless my shirt studs!" exclaimed Mr. Damon, who was the first to speak
+after the din had quieted. "Bless my soul! But that was awful!"
+
+"It was just what I expected," said Mr. Parker, calmly. "I knew, from
+my observations, that we were in a region where landslides and terrific
+electrical storms may be expected at any time. I fully looked for this."
+
+"Well," remarked Mr. Jenks, rather sarcastically, "I hope it came up to
+your expectations, Mr. Parker."
+
+"Oh, fully," was the answer, "though I wish it could have happened
+in daylight, so that I could better have observed certain phenomena
+regarding the landslide. They are very interesting."
+
+"At a distance," admitted Tom, with a laugh of relief. "Well, I'm glad
+it's over, though we'll have to wait until morning to see what damage
+has been done. Lucky we weren't struck by lightning. I never saw such
+bolts!"
+
+"Me, either!" declared Mr. Damon. "This mountain seems to attract them."
+
+"It is like a magnet," said Mr. Parker. "I think I shall be able to make
+some fine observations here."
+
+"If we live through it," murmured Mr. Jenks.
+
+They watched the play of lightning about a distant bank of clouds,
+but the storm was now far away, only a faint rumbling of thunder being
+heard.
+
+"I'm wondering what happened to the phantom," said Tom, after a pause.
+"Seems to me he was right in that track of the storm."
+
+"Do you think it was a 'he'?" asked Mr. Jenks.
+
+"I think we'll find that it's some sort of a man," answered the young
+inventor. "We may find out very soon, now. I've changed my theory about
+the ghost being reflections of light."
+
+"How's that?" Mr. Damon wanted to know.
+
+"Well, I think we are on the side of Phantom Mountain where the diamond
+cave is," went on the lad. "The fact that the phantom appeared here,
+soon after we arrived, shows that the men kept close track of our
+movements. It also shows, I think, that the phantom did not have to
+travel far to be on the spot, whereas we had to make quite a trip to get
+around the base of the mountain. I think the cave is up there," and
+Tom pointed toward the spot where the weird figure had been last seen,
+before the storm drove it back.
+
+"There may be two phantoms," suggested Mr. Jenks. "They may keep one on
+this side of the mountain, and one on the other, to warn intruders away.
+
+"It's possible," admitted Tom. "Well, we'll see how things look in the
+morning, when we'll take up our march again, and go up the mountain.
+We'll reach the top, if possible, which we couldn't do from the other
+side, as it was too steep."
+
+"I hope we shall be able to go forward in the morning," came from Mr.
+Jenks.
+
+"What do you mean?" asked the lad, struck by a peculiar significance in
+the diamond man's tones.
+
+"Why, that landslide may have opened a great gully in the side of
+Phantom Mountain, which will prevent us from passing. It was a terrific
+lot of earth and stones that slid away," answered Mr. Jenks.
+
+"It certainly was," agreed Mr. Parker. "I would not be surprised if
+the mountain was half destroyed, and it may be that the diamond cave no
+longer exists."
+
+"Not very cheerful, to say the least," murmured Mr. Jenks to Tom, and,
+as it was getting quite chilly, following the storm, they went inside
+the tent.
+
+Tom could hardly wait for daylight, to get up and see what havoc the
+landslide had wrought. As soon as the first faint flush of dawn showed
+over the eastern peaks, he hurried from the tent. Mr. Damon heard him
+arise, and followed.
+
+A curious scene met their eyes. All about were great rocks rent and torn
+by the awful power of the lightning. The fronts of the stone cliffs
+were scarred and burned by the electrical fire, and fantastic markings,
+grotesque faces, and leering animals seemed to have been drawn by some
+gigantic artist who used a bolt from heaven for his brush.
+
+But the eyes of Tom and Mr. Damon took all this in at a glance, and then
+their gaze went forward to where the avalanche had torn away a great
+part of the mountain.
+
+"Whew! I should say it was a landslide!" cried Tom.
+
+"Bless my wishbone, yes!" agreed Mr. Damon.
+
+Below them, in the valley, lay piled immense masses of earth and stones.
+Boulders were heaped up on boulders, and rocks upon rocks, being tossed
+about in heaps, strung about in long ridges, and swirled about in
+curves, as though some cyclone had toyed with them after the lightning
+flash had tossed them there.
+
+"But the mountain isn't half gone," said Tom, as his eyes took in what
+was left of the phantom berg. "I guess it will take a few more bolts
+like that one, to put this hill out of business."
+
+Though the landslide had been a great one, the larger part of the
+mountain still stood. An immense slice had been taken from one side, but
+the summit was untouched.
+
+"And there's where the diamond cave is!" cried Tom, pointing to it.
+
+"I think so myself," agreed Mr. Jenks, who came from the tent at that
+moment, and joined the lad and Mr. Damon. "I think we shall find the
+cave somewhere up there. We must start for it, as soon as we have eaten,
+and we may reach it by night."
+
+The three stood gazing up toward the summit of the great mountain.
+Suddenly, as the sun rose higher in the heavens, it sent a shaft of rosy
+light on the face of the berg that had been scarred by the landslide.
+Tom Swift uttered an exclamation, and pointed at something.
+
+"See!" he cried. "Look where the trail is--the trail down which the
+phantom must have come. It is on the edge of a cliff now!"
+
+They looked, and saw that this was so. The increasing light had just
+revealed it to them. When the lightning bolt had torn away a great
+portion of the mountain it had cut sheer down for a great depth and
+when the earth and stones fell away they left a narrow pathway, winding
+around the mountain, but so near the edge of a great chasm, that there
+was room but for one person at a time to walk on that footway. The
+uncertain trail up Phantom Mountain had all but been destroyed.
+
+"The way up to the peak is by that path, now," spoke Tom, in a low
+voice.
+
+"Bless my soul!" cried Mr. Damon. "It's as much as a man's life is worth
+to attempt it. If he got dizzy, he'd topple over, and fall a thousand
+feet. Dare we risk it?"
+
+"It's the only way to get up," went on Tom. "It's either that way, or
+not at all. We've tried the other side without success. We must go up
+this way--or turn back."
+
+"Then we'll go up!" cried Mr. Jenks. "It may not be as dangerous as it
+looks from here."
+
+But it was even more dangerous than it appeared, when they went part way
+up it after a hasty breakfast. The trail was a mere ledge of rock now,
+and in some places, to get around a projecting edge of the mountain,
+they had to stand with their backs to the dizzy depths at their feet,
+and with both arms outstretched work their way around to where the trail
+was wider.
+
+"Shall we risk it?" asked Tom, when they had tried the way, and found
+it so dangerous. "We can't take anything with us--even our guns, for
+we couldn't carry them, and if we reach the mouth of the cave, and find
+those men there--"
+
+He paused significantly. The adventurers looked at one another. The
+search for the diamond makers was becoming more and more dangerous.
+
+"I say let's go on!" decided Mr. Damon, suddenly. "We want to locate
+that cave, first of all. Perhaps, when we do find it, we may see some
+easier way of getting to it than this. And if those diamond makers do
+attack us--well, I don't believe they'll shoot defenseless men, and they
+may listen to reason, and give Mr. Jenks his rights--tell him how to
+make diamonds in return for the money he gave them."
+
+"I don't believe those scoundrels will listen to reason," replied the
+diamond man, "but I agree with Mr. Damon that we ought to go on. We may
+find some other means of reaching the cave--if we can discover it, and
+we'll take a chance with the men."
+
+"Forward it is, then!" cried Tom. "I have a revolver, and I can supply
+one of you gentlemen with another. They may come in useful in an
+emergency. Let's go back to camp, take a little lunch in our pockets,
+and try to scale the mountain."
+
+They were soon on their way up the dizzy path once more, and, as they
+advanced, they found it growing more and more dangerous. In some places
+they found it almost impossible to get around certain corners, where
+there was barely room for their feet. As Tom remarked grimly, a fat man
+never could have done it. Fortunately they were all comparatively thin,
+for their hard work, and not too abundant food, since they had left the
+airship, had reduced their weight.
+
+Up and up they went, higher and higher, sometimes finding the path wide
+enough for two to walk abreast, and again seeing it narrow almost to
+a ribbon. They hardly dared look down into the chasm at their left--a
+chasm filled, in part, with the rocks and boulders tossed into it by the
+lightning bolt.
+
+Tom was in the lead, and had just made a dangerous turn around a
+shoulder of rock--one of those places where he had to extend both arms,
+and fairly hug the cliff before he could get around.
+
+But, when he had made it, and found himself on a broad pathway, cut
+in the living rock, he gave a great shout--a shout that caused his
+companions to hasten to his side. They found the young inventor pointing
+to a clump of bushes and small trees.
+
+But it was not the shrubbery that Tom desired to call to their
+attention. They saw that in an instant, for, dimly seen through the
+leaves, was something black, and, as they looked more closely, they saw
+that it was a great hole in the side of the mountain--a vast cavern,
+opening like a tunnel.
+
+"The cave! The cave!" cried Tom. "The diamond makers' cave!"
+
+Hardly had he spoken than two men, each one carrying a gun, showed
+themselves in the mouth of the cavern, and, instant later they both ran
+toward the little party of adventurers.
+
+
+
+
+CHAPTER XVII--THE PHANTOM CAPTURED
+
+
+Surprise held Tom and his friends almost spellbound for the moment.
+The young inventor's hand went toward the pocket where he carried his
+revolver. Mr. Jenks, who had the only other weapon, sought to draw it,
+but he was stopped by a gesture of one of the two men with guns.
+
+"Hold on, strangers!" the man cried. "I know what you're up to! Better
+not try to draw anything--it might not be healthy. Now, then, who are
+you, and what do you want?"
+
+The question came rather as a surprise, at least to Tom and Mr. Jenks.
+They had taken it for granted that these men--if they were the diamond
+makers--would know Mr. Jenks, and guess at his errand in coming back
+to Phantom Mountain. But, it seemed, that they took them all for casual
+strangers.
+
+No one answered for a moment. Tom caught the eye of Mr. Jenks, and there
+was a look of hope in it. If ever there was a time for strategy, it was
+now. Evidently Munson, the stowaway on the airship, had not yet been
+able to send a warning to his confederates. And neither of the two men
+recognized Mr. Jenks as the man who had been defrauded of his rights.
+It might be possible to conceal the real object of the adventurers until
+they had time to formulate a plan of action.
+
+"Well," exclaimed the man with the gun, impatiently, "I ask you folks a
+question. What do you want?"
+
+Fortunately, neither Mr. Damon nor Mr. Parker replied. The former
+because he deferred to Tom and Mr. Jenks, and the scientist because he
+was busy inspecting some curious rocks he picked up. As it turned out
+this was the luckiest thing he could have done. It lent color to what
+Mr. Jenks said a moment later.
+
+"What are you doing up here?" demanded the man again. "Don't you know
+this is private property?"
+
+"We--we were just looking around," answered Mr. Jenks, which was true
+enough; as far as it went.
+
+"Prospecting," added Tom.
+
+"After gold?" demanded the second man, suspiciously.
+
+"We'd be glad to find some," retorted the lad. At that moment Mr. Parker
+began breaking off bits of rock with a small geologist's hammer which he
+carried. The men with the guns looked at him.
+
+"So you think you'll find gold up here?" asked the one who had first
+spoken.
+
+"Is there any?" inquired Tom, trying to make his voice sound eager.
+
+"Nary a bit, strangers," was the answer, and the two men laughed
+heartily. "Now, we don't want to seem harsh," went on the man who seemed
+to be the spokesman, "but you'd better get away from here. This is
+private ground, and dangerous too--how'd you ever get up the trail--we
+heard it was destroyed."
+
+"There is still a narrow path," said Mr. Jenks. "We came up that--the
+lightning and landslide haven't left much of it, though."
+
+Mr. Parker looked quickly up from the rocks at which he was tapping with
+his small hammer. "You have terrific lightning up here," he said. "I am
+much interested in it, from a scientific standpoint. I predict that some
+day the entire mountain will be destroyed by a blast from the sky."
+
+"I hope it won't be right away," spoke one of the men. "Now I guess you
+folks had better be leaving while there's a path left to go down by."
+
+"Might I ask," broke in Mr. Parker, as calmly as though he was lecturing
+to a class of students, "might I ask if you have noticed any peculiar
+effect of the lightning up here on the summit of the mountain? Does it
+fuse and melt rocks, so to speak?"
+
+"What's that?" cried the spokesman, with a sudden flash of anger. The
+two men looked at each other.
+
+"I wanted to know, merely for scientific reasons, whether the lightning
+up here ever melted rocks?" repeated Mr. Jenks.
+
+"Well, whether it's for scientific reasons or for any other, I'm not
+going to answer you!" snapped the man. "It's none of your affair what
+the lightning does up here. Now you'd all better 'vamoose'--clear out!"
+
+"All right--we'll go," said Tom, quickly, at the same time motioning to
+Mr. Jenks to agree with him. The eyes of the young inventor were
+roving about. He saw what looked like a second trail, leading down the
+mountain, from the far side of the cave. He was convinced now that there
+was another way to get to it. Possibly they might find it. At any rate
+nothing more could be done now. They must go back, for the cavern was
+too well guarded to attempt to enter it by force--at least just yet.
+
+"Yes, we'll go back," assented Mr. Jenks.
+
+Mr. Parker was tapping away at the rocks. He looked toward the black
+mouth of the big cave. On what corresponded to the roof of it, some
+distance back from the entrance, he saw a slender metal rod sticking up
+into the air.
+
+"May I ask if that's a lightning rod?" he inquired innocently. "If
+it is, I should like to ask about its action in a mountain that is so
+impregnated with iron ore.
+
+"You may ask until you get tired!" cried the spokesman, again showing
+unreasoning anger, "but you'll get no answer from us. Now get away from
+here before we do something desperate. You're on private ground and
+you're not wanted. Clear out while you have the chance."
+
+There was no help for it. Slowly our friends turned and began to go
+down the dangerous trail. They were soon out of sight of the two men who
+stood before the cave, with their guns ready, but neither Tom nor any of
+his companions spoke for some time.
+
+When they had rounded one of the most dangerous turns the young inventor
+sat down to rest, an example followed by the others.
+
+"Well," asked Tom, "do you think those are some of the diamond makers,
+Mr. Jenks?"
+
+"I certainly do, though I never saw those two men before. If I could
+once get inside the cave, I could tell whether or not it was the one
+where I was practically held a prisoner. But I'm sure it is. I know some
+of the men used to go off every day with guns, and not come back until
+night. I have no doubt they were on guard, just as these two are. And,
+also, I think I heard them speak of a second entrance to the cavern. The
+one we just saw may not be the main one, through which I was taken."
+
+"I believe we are on the right track," ventured Mr. Damon, "but we will
+either have to go up there after dark, which will be risky, on account
+of the narrow trail, or else we will have to find some other path."
+
+"The last would be better," spoke Tom.
+
+"That rod of metal sticking up on top of the cave interested me," said
+the scientist. "Did you hear anything of that when you were here before,
+Mr. Jenks?"
+
+"No. Probably that is only a lightning rod, or it may be a staff for a
+signal flag. But what surprises me is that those men didn't suspect
+that we were seeking to discover their secret. They took us for ordinary
+prospectors."
+
+"So much the better," remarked Tom. "We have a chance now of getting
+inside that cave. But we will have to go back to camp, and make other
+plans. And we must hurry, or it will be dark before we get there."
+
+They hastened their steps, pausing only briefly to eat some of the lunch
+they had brought along, and to drink from a spring that bubbled from the
+side of the mountain. It was getting dusk when they got back to their
+tent. They found nothing disturbed.
+
+"I wonder if we'll see that phantom again to-night?" ventured Tom, as
+they were sitting about the campfire a little later.
+
+"Probably not," remarked Mr. Jenks. "I don't believe the ghost will
+venture down the dangerous trail after dark, and the gang may think
+that the warning given us by the two men on guard at the cave will be
+sufficient. But if we don't leave here by to-morrow I think we will have
+another visit from the thing in white."
+
+It was about an hour after this when Tom was collecting some wood in a
+pile nearer the fire, so as to have it ready to throw on, in case there
+was any alarm in the night, that he happened to look up toward the
+summit of the mountain. A slight noise, as of loose stones rolling down,
+attracted his attention, and, at first, he feared lest another landslide
+was beginning, but a moment later he saw what caused it.
+
+There, advancing down the steep and dangerous trail was the figure
+in white--the phantom. Instantly a daring plan came into Tom's head.
+Dropping the wood softly, he moved back out of the glare of the fire.
+
+"Mr. Jenks!" he called in a whisper.
+
+The diamond man, who was behind the tent, came toward Tom.
+
+"What is it?" he asked. Then, as he saw the ghostly visitor, he added:
+"Oh--the phantom again! What's it up to?"
+
+"The same thing," replied Tom, "but it won't do it long, if my plan
+succeeds."
+
+"What plan is that, Tom?"
+
+"I'm going to try to capture that--that man--or whatever it is. Will you
+help?"
+
+"Surely!"
+
+"Then let's work around behind it, while Mr. Damon and Mr. Parker come
+up from in front. We'll solve this part of the mystery, anyhow, if it's
+possible!"
+
+The two other men were soon told of the plan. Meanwhile the thing in
+white had advanced slowly, until within a few hundred feet of the camp.
+They could see now that it was no shaft of light, but some white body,
+shaped like a tall, thin man, draped in a white garment. The long arms
+waved to and fro. There was no semblance of a head.
+
+"You and Mr. Parker go right toward it, slowly, Mr. Damon," advised
+Tom. "Mr. Jenks and I will make a circle, and get in back. Then, if it's
+anything alive we'll have it."
+
+The "ghost" continued to advance. Tom and the diamond man stole off to
+one side, their buckskin moccasins making no sound. Mr. Damon and the
+scientist went boldly forward.
+
+This movement appeared to disconcert the spirit. It halted, waved the
+arms with greater vigor than before, and seemed to indicate to the
+adventurers that it was dangerous to advance. But Mr. Damon and Mr.
+Parker kept on. They wanted to give Tom and Mr. Jenks time enough to
+make the circuit.
+
+Suddenly the stillness of the night was broken by a low whistle. It was
+Tom's signal that he and Mr. Jenks were ready.
+
+"Come on! Run!" cried Mr. Damon.
+
+The scientist and the eccentric man leaped forward.
+
+The "ghost" heard the whistle, and heard the spoken words. The thing in
+white hesitated a moment, and then raised one arm. There was a flash of
+fire, and a loud report.
+
+"He's firing in the air!" cried Tom. "Come on, we have him now!"
+
+Undaunted by the display of firearms, Mr. Damon and Mr. Parker kept on.
+They could hear Tom and Mr. Jenks running up in back of the figure.
+The latter also heard this, and suddenly turned. Caught between the two
+forces of our friends, the "ghost" was at a loss what to do.
+
+The next instant Tom, who had distanced Mr. Jenks, made a flying tackle
+for the figure in white, and caught it around the legs. Very substantial
+legs they were, too, Tom felt--the legs of a man.
+
+"Wow!" yelled the "ghost," as he went down in a heap, the revolver
+falling from his hand.
+
+"Come on!" cried Tom. "I have him!"
+
+His friends rushed to his aid. There was a confused mass of dark bodies,
+arms and legs mingled with something tall and thin, all in white.
+Suddenly the moon came from behind a cloud and they could see what they
+had captured--for captured the phantom was.
+
+It proved to be a rather small man, who wore upon his shoulders a
+framework of wood, over which some white cloth was draped. It had fallen
+off him when Tom made that tackle.
+
+"Well," remarked the young inventor, as he sat on the struggling man's
+chest. "I guess we've got you."
+
+"I rather guess you have, stranger," was the cool reply.
+
+
+
+
+CHAPTER XVIII--BILL RENSHAW WILL HELP
+
+
+They were all panting from the exertion of the run up the mountain and
+the contest with the phantom--a phantom no longer--though, truth to
+tell, the struggle was not nearly so fierce as Tom had expected. He
+thought the "ghost" would put up a stiff fight.
+
+"Got any ropes to tie him with?" asked Mr. Damon, who was helping Tom
+hold the man down.
+
+"Ropes? You aren't going to tie me up are you, strangers?" asked the
+captive.
+
+"That's what we are!" exclaimed Mr. Jenks. "We've had trouble enough in
+this matter, and if I've got one of the gang, perhaps I can get some of
+the others, and have my rights. So tie him up, Tom, and we'll take him
+to camp.
+
+"Oh, you needn't go to all that trouble, strangers," went on the man,
+calmly. "If one of you will get off my chest, and the other gentleman
+ease up on my stomach a bit, I'll walk wherever you want me, and not
+make any trouble. I haven't got a gun."
+
+"Bless my gloves! But you're a cool one," commented Mr. Damon, as he
+complied with the man's request, and got up from his stomach. "But look
+out for him, Tom. He had a gun, for he fired it in the air."
+
+"He hasn't it now," answered the young inventor. "I knocked it from his
+hand when I leaped for him."
+
+"That's what you did," assented the man, as he got up, while Tom kept a
+tight hold of him, as did Mr. Jenks. "What kind of a grizzly bear hug do
+you call that, anyhow, that you gave me?"
+
+"That was a football tackle," explained Tom.
+
+"I allers heard that was a dangerous game!" remarked the former phantom
+simply. "Well, now you've got me, what are you going to do with me?"
+
+"Take you where we can have a good look at you," replied Mr. Jenks, as
+he kicked aside the wooden framework, and the sheet which had made the
+"ghost" appear so tall. "So this is how you worked it; eh?"
+
+"Yep. That was the 'haunt' stranger. I made it myself, and it worked all
+right until you folks come along. I rather suspicioned from the first,
+when I played the trick over on 'tother side of the mountain, that you
+wouldn't be so easy to fool as most prospectors are."
+
+"Oh, so you're the only ghost then?" asked Tom.
+
+"I'm the only one."
+
+By this time they had reached the camp. Tom threw some light logs on the
+fire, which blazed up brightly. As the flames illuminated the face of
+their captive, Mr. Jenks looked at him, and cried out:
+
+"Why it's Bill Renshaw!"
+
+"That's me," admitted the man who had played the part of the phantom,
+"and thunder-turtles! if it ain't Mr. Jenks who was once in the diamond
+cave with us. Whatever happened to you? I never heard. The others said
+you got tired and went away."
+
+"They took me away--defrauded me of my rights!" declared Mr. Jenks,
+bitterly. "But I'll get them back! To think of Bill Renshaw playing the
+part of a ghost!"
+
+"They made me do it," went on the man, somewhat dejectedly. "I wanted to
+be at work in the cave, but they wouldn't let me."
+
+"Is this man one of the diamond makers?" asked Tom, in great surprise.
+
+"He is--one of the helpers, though I don't believe he knows the secret
+of making the gems," explained Mr. Jenks. "He was one of the men in the
+cave when I was there before, and he and I struck up quite a friendship;
+didn't we, Renshaw?"
+
+"That's what, and there ain't no reason why we can't be friends now;
+that is unless you hold a grudge against me for firing at you. But I
+only shot in the air, to scare you away. Them's my instructions. I'm
+supposed to be on guard, and scare away strangers. I'm tired of the
+work, too, for I don't get my share, and those other fellows, in the
+cave, get all the money from the diamonds."
+
+Tom Swift uttered an exclamation. A sudden plan had come to him. Quickly
+he whispered to Mr. Jenks:
+
+"Make a friend of this man if possible. He evidently is dissatisfied.
+Offer him a sum to show us another way into the cave, and we may yet
+discover the secret of the diamond makers."
+
+"I will," declared Mr. Jenks, quietly. Then, turning to Renshaw, he
+added:
+
+"Bill, come over here. I want to have a talk with you. Perhaps it will
+be to our mutual advantage."
+
+He led the former phantom to one side, and for some time conversed
+earnestly with him. Mr. Jenks told the story of how he had been deceived
+by Folwell and the others who were at the head of the gang of diamond
+makers. The rich man related how they had taken his money, and, after
+promising to disclose the secret process to him, had broken faith, and
+had drugged him, afterward taking him out of the cave.
+
+"I want only my rights, and that for which I paid," concluded Mr. Jenks.
+"Now, I gather that these men haven't treated you altogether fairly,
+Bill."
+
+"Indeed they haven't. I helped 'em to the best of my ability, and all
+I get out of it is to stay out on this lonely side of the mountain,
+and play ghost. They owe me money, too, and they won't pay me, either,
+though they have lots, for they sold some diamonds lately."
+
+"Then they are still making diamonds?" asked Mr. Jenks, eagerly. "Have
+you seen them? Do you know the secret?"
+
+"No, I don't know it, for they won't let me in on it. I'm always sent
+out of the cave just before they make the gems. But I know they've made
+some lately, and have sold 'em. I want my share."
+
+"Look here!" exclaimed Mr. Jenks, quickly, wishing to strike while the
+iron was hot. "I'll make you a proposition. Show us how to get into that
+cave, unknown to the diamond makers, and I'll pay you twice what they
+agreed to. Is it a bargain?"
+
+Bill Renshaw considered a moment. Then he thrust out his hand, clasped
+that of Mr. Jenks, and exclaimed:
+
+"It is. I'll take you into the cave by an entrance that's seldom used.
+There are four ways to get in. The one where the two men drove you back
+is the rear one. The front one is on the other side of the mountain, but
+it's so well concealed that you'd never find it. But I can take you to
+one where you can get in, and those fellows will never know it. And,
+what's more, I'll help you if it comes to a fight!"
+
+"Good!" exclaimed Mr. Jenks. "I think we'll discover the secret of the
+diamond makers this time," and he went to tell the others of the success
+of his talk. Bill Renshaw had been converted from an enemy into a
+friend, and the former phantom was now ready to lead Tom and the others
+into the secret cave.
+
+"We'll start in the morning," decided Mr. Jenks, who, after many
+disappointments, at last saw success ahead of him.
+
+
+
+
+CHAPTER XIX--IN THE SECRET CAVE
+
+
+Tom Swift was up at break of day, and the others were not far behind
+him.
+
+"Now for the secret cave!" cried the young inventor as he gazed up
+the mountain, in the interior of which the mysterious band of men were
+making the diamonds.
+
+"Have you made any plans, Bill?" asked Mr. Jenks of the former phantom,
+who had cast his lot in with the adventurers. "What will be the best
+course for us to follow?"
+
+"You just leave it to me, Mr. Jenks," was the answer. "I'll get you into
+the cave, and those fellows, who, I believe, are trying to do me out of
+my rights, as they did you out of yours, will never know a thing about
+it."
+
+"Bless my finger-nails!" cried Mr. Damon. "That will be great! We can
+get in the cave, and watch them make the diamonds at our leisure."
+
+"They don't make them every day," explained Renshaw. "It seems they
+have to wait for certain occasions. Mostly they make the diamonds when
+there's a big storm."
+
+"A big storm," asked the scientist with a sudden show of interest.
+"Do you mean one of those electrical storms, such as we had the other
+night?"
+
+"That's it, Mr. Parker, though why they wait until there's a storm is
+more than I can tell."
+
+"Perhaps they know that on such occasions no one will venture up the
+mountain," spoke Mr. Damon.
+
+"No, it isn't that," declared the scientist. "I think I am on the
+track of a great scientific discovery, and I will soon be able to make
+observations that will confirm it."
+
+"Well, I'm going to make an observation right now," said Tom, with a
+laugh. "I'm going to see what there is for breakfast."
+
+"And that reminds me," came from Mr. Jenks, "shall we move our camp,
+Bill, and take the tent with us to the cave?"
+
+"I hardly think so," was the answer. "I think the best plan would be to
+conceal the tent somewhere around here, in case you might need it again.
+You can also store what food you have left."
+
+"But, bless my appetite, we don't want to starve in that diamond cave!"
+objected Mr. Damon.
+
+"I'll see that you don't," declared Bill Renshaw. "I'll take you in
+there, unbeknownst to those fellows, and I'll provide you with plenty
+of food and water. You see the cave is so big that there are some parts
+they never visit."
+
+"And we can stay in one of those parts, and eat?" asked Tom.
+
+"Sure," answered Bill.
+
+"And watch the diamond makers at work?" asked Mr. Jenks.
+
+"That's it," replied the former phantom.
+
+"Then the sooner we get started the better," remarked Mr. Damon. Mr.
+Parker said nothing. He appeared to be thinking deeply, and was tapping
+at some rocks with his little hammer.
+
+The advice of Bill Renshaw was followed, and the tent, and what food
+remained, was concealed in the bushes, with rocks piled over to keep
+away prowling animals. Then they started for the secret cave.
+
+The man who played the part of a ghost picked up the framework and white
+cloth that had formed his disguise.
+
+"I'll still have to use this," he explained, "for I don't want those
+fellows to know that I'm helping you. I'll continue to play the spirit
+of the mountain, but there won't be much need of it. I don't think any
+more people will come prospecting out here."
+
+"Have you heard of the arrival of Farley Munson?" asked Tom, as he
+related the facts about the stowaway.
+
+"He hadn't arrived up to a day or so ago," answered Bill. "I guess he's
+still traveling. Farley is one of the heads of the gang," he added, "and
+a dangerous man."
+
+As Bill led the way toward the cave, taking a route that the adventurers
+had never suspected led to it, he explained that the cavern was a large
+one, capable of holding an army.
+
+"But there's only a small part of it used by the diamond makers," he
+added. "They work in a small recess, near the summit of the mountain.
+The little cave, where I'm going to take you, opens off from it by a
+long passage. And, except that you'll be pretty much in the dark, you'll
+be quite comfortable. There are tables, chairs, and some bunks in the
+place. I can get you some lights, and plenty of food."
+
+"But, if you are seen taking away food, won't the others suspect
+something?" asked Tom.
+
+"I do pretty much as I please," said Bill. "I go and come when I like.
+All I'm supposed to do is to watch my two sides of the mountain, play
+the ghost, and give warning when any one is coming. Sometimes I leave
+black and white messages, like the one I put on your tent. Those fellows
+fix 'em up for me. I've told 'em about you, though I didn't know who you
+were, and they think you have gone, for the two men on guard at the rear
+entrance so reported. Sometimes I stay out on the mountain for a couple
+of days at a time, when the weather's good, and don't go back to the
+cave. Those times I take food with me, and so if they see me making off
+with some supplies they'll think I'm going to camp out."
+
+"It doesn't look as though we'd ever get into a cave near the top of the
+mountain, going this way," said Tom, as they marched along. "We're going
+down, instead of up."
+
+"That's the secret of this trail," explained Bill. "We go down in a
+sort of valley, and then go up a pretty stiff place, and then we're on
+a direct trail to the entrance I told you about. It's a steep road to
+climb, but I guess we can manage it."
+
+And a hard climb the adventurers did find it. The road was almost as bad
+as the one along the edge of the chasm, but they managed to negotiate
+it, and finally found themselves on a fairly good trail.
+
+"We'll soon be there," Bill assured them. "After you get in the little
+cave, where I'm going to hide you, I'll have to leave you for a spell,
+until I get my ghost rigging fixed up again. But I'll see that you have
+plenty of food and drink."
+
+A little later their guide came to a sudden halt, and peered around
+anxiously.
+
+"What's the matter?" asked Tom.
+
+"I was just looking to see if any of the men were about," he answered.
+"But I guess not--it looks all right. The entrance is right here."
+
+They were on a side of the mountain, near the summit. Below stretched a
+magnificent scene. A great valley lay at their feet, and they could look
+off to many distant peaks. The main trail to Leadville, and the one to
+the settlement of Indian Ridge, was in sight.
+
+Suddenly Tom, who had been using a small but powerful telescope, uttered
+an exclamation, and focussed the instrument on a speck that seemed
+moving along on the trail below.
+
+"A man--coming up the mountain," cried Tom. "And--it can't be--yet it
+is--it's Farley Munson--the stowaway!" he cried. "He's coming here!"
+
+"Let me look!" begged Mr. Jenks, taking the glass from Tom. An instant
+later the diamond man exclaimed: "Yes, it's Munson!"
+
+"Then in here with you--quick!" cried Renshaw. "He can't see us yet, and
+we'll be out of sight in another minute."
+
+The former spirit pulled aside some thick bushes, and pointed to a hole
+which was disclosed.
+
+"The entrance to the secret cave," he announced. "Slip in all of you."
+
+Tom, after another glance at the man toiling his way up the mountain,
+entered the cavern. He was followed by the others. Bill was the last to
+enter, and he replaced the bushes over the entrance.
+
+"At last!" exclaimed Mr. Jenks, as he gazed up at the roof of the
+dimly-lighted vault in which they found themselves.
+
+"Yes, we're in the diamond makers' secret cave," added Tom. "Now to
+catch them at work!"
+
+"Come on," advised Bill, in a low tone, "We're not safe yet," and he
+produced a lantern from some hidden recess, lighted the wick, and led
+the way. As the others followed they were aware of a subdued noise in
+the great cavern.
+
+
+
+
+CHAPTER XX--MAKING THE DIAMONDS
+
+
+"What's that noise?" asked Tom, as their guide flashed the lantern to
+show them the way.
+
+"That's the men getting ready to make diamonds, I guess," was the
+answer. "You see it takes quite a while to get the stuff ready. I don't
+know what they use--they never tell me any of their secrets."
+
+"Oh, I know the ingredients well enough," said Mr. Jenks, "but I
+don't know the secret of how they apply the terrific heat and pressure
+necessary to fuse the materials into diamonds."
+
+"Well, you'll soon know," declared Bill Renshaw. "Of course it isn't
+always successful. I've known 'em to try half a dozen times before they
+got any diamonds big enough to satisfy 'em. They gave me some of the
+small ones when I asked for my wages.
+
+"How did you come to get in with these men?" asked Tom, curious to
+understand how a person seemingly as honest as Renshaw appeared to be
+had cast his lot in with the men who had broken faith with Mr. Jenks.
+
+"Oh, I've lived around these parts all my life," was the answer. "I knew
+of this cave before these diamond fellers came to it. In fact, I
+showed it to 'em. It was several years ago that a party of men who were
+prospecting around here came to me and asked if I knew of a small cave
+near the top of a high mountain, where lightning storms were frequent.
+I told them about Phantom Mountain, as it was called then, and also of
+this cave. If there's any place where they have worse lightning storms
+than here, I'd like to know it. They scare me, sometimes, like the night
+when that landslide happened, and I'm sort of used to 'em.
+
+"Well, I took these men to the cave, and they hired me as a sort of
+lookout. Then they began their work, and at first I didn't know what
+they were up to, but finally I caught on. Then Mr. Jenks came, and
+disappeared mysteriously, though then I didn't know that they had played
+a trick on him. I was outside most of the time, pretending I was the
+ghost. So that's how I came to get in with 'em, and I wish I was out."
+
+"You soon will be, I think," declared Mr. Jenks. "But won't our talking
+be heard by the men?"
+
+"No danger. There is a thick wall between this part of the cave, and the
+part where they live and work. I'll soon have you well hid, and then you
+wait until I come back."
+
+"What about Munson?" asked Tom. "He is evidently on his way here to tell
+his confederates about us."
+
+"He won't know what has happened to us," said Mr. Jenks, "and he won't
+see anything of us. I guess we're safe enough."
+
+Through the dark passage they followed Bill Renshaw until he came to a
+halt in a place that suddenly widened and broadened into a good-sized
+cave.
+
+"Here's your stopping place," said the former ghost. "Now if you follow
+that passage, off to the left," and he pointed to it, "you'll come
+to the larger part of the cave where the diamond makers are. But go
+cautiously, and don't make any noise. I won't be responsible for what
+happens."
+
+"We'll take all the risk," interrupted Tom.
+
+"All right. Now there's a couple of lanterns around here. I'll light
+them, and leave you for a while until I can get some grub. I'll be back
+as soon as I can."
+
+He glided away, after lighting two lanterns, by the gleams of which
+the adventurers could see that they were in a vaulted cavern that had
+evidently been fitted up as a living apartment. The sides, roof and
+floor were of stone. It was clean, and the air was fresh. There were
+some chairs, a table, and several cots, with pieces of bagging for
+bedding, though it was warm in the place.
+
+"I guess we can stay here until we discover the secret," spoke Tom.
+
+"Bless my watch! We can if we have something to eat," came from Mr.
+Damon, with something like a sigh. "I'm hungry!"
+
+"And I want to make some observations," said Mr. Parker. "From what I
+have seen of this mountain, I would not be surprised if this cave was
+to be suddenly destroyed by a landslide or a lightning bolt. I will make
+some further investigations."
+
+"Well, if it's going to cause you to make such gloomy prophecies as
+that, I'd just as soon you wouldn't look any further," spoke Tom, in
+a low voice. But Mr. Parker, taking one of the lanterns, set about
+examining the rock of which the cave consisted.
+
+In a short time Bill Renshaw returned with enough food to last for two
+days. He said he was going out on the mountain once more to act the part
+of a lookout, and would visit the adventurers again the next day.
+
+"In the meanwhile you can do just as you please," he said. "Nobody is
+likely to disturb you here, and you can sneak up and take a look at the
+men in the other cave whenever you're ready. Only be careful--that's all
+I've got to say. They're desperate men."
+
+It was not very pleasant, eating in the gloomy cavern, but they made the
+best of it. They cooked on a small oil-stove they found in the place,
+and after some hot coffee they felt much better.
+
+"Well," remarked Tom, after a while, "shall we take a chance, and go
+look at the men at work?"
+
+"I think so," answered Mr. Jenks. "The sooner we discover this mystery,
+the better. Then we can go back home."
+
+"And recover my airship," added Tom, who was a bit uneasy regarding the
+safety of the Red Cloud.
+
+"Then, bless my finger-rings! let's go and see if we can find the big
+cave your friend the ghost told us of," suggested Mr. Damon.
+
+Cautiously they made their way along the passage Bill had pointed out.
+As they went forward the subdued noise became louder, and finally they
+could feel the vibration of machinery.
+
+"This is the place," whispered Mr. Jenks. "That sound we hear is one of
+the mixing machines, for grinding the materials--carbon and the other
+substances--which go to make up the diamonds. I remember hearing that
+when I was in the cave before."
+
+"Then we must be near the place," observed Tom.
+
+"Yes, but I didn't have much chance to look around when I was here
+before. They wouldn't let me. I never even knew of the small cave Bill
+took us to."
+
+"Well, if we're close to it, we'd better go cautiously, and not talk any
+more than we're obliged to," suggested Mr. Parker, and they agreed that
+this was good advice.
+
+They walked on softly. Suddenly Tom, who was in the lead, saw a gleam of
+light.
+
+"We're here," he whispered. "I'll put out our lantern, now," which he
+did. Then, stealing forward he and the others beheld a curious sight.
+The tunnel they were in ended at a small hole which opened into a large
+cavern, and, fortunately, this opening was concealed from the view of
+those in the main place.
+
+"The diamond makers!" whispered Tom, hoarsely, pointing to several men
+grouped about a number of strange machines.
+
+"Yes--the very place where I was," answered Mr. Jenks, "and there is the
+apparatus--the steel box--from which the diamonds are taken--now to see
+how they make them."
+
+Fascinated, the adventurers looked into the cave. The men there were
+unaware of the presence of our friends, and were busily engaged. Some
+attended to the grinding machine, the roar and clatter of which made
+it possible for Tom and the others to talk and move about without being
+overheard. Into this machine certain ingredients were put, and they were
+then pulverized, and taken out in powdery form.
+
+The power to run the mixing machine was a gasoline motor, which
+chug-chugged away in one corner of the cave.
+
+As the powder was taken out, other men fashioned it into small balls,
+which were put on pan, and into a sort of oven, that was heated by a
+gasoline stove.
+
+"Is that how they make the diamonds?" asked Mr. Damon.
+
+"That is evidently the first step," said Mr. Jenks. "Those balls of
+powdered chemicals are partly baked, and then they are put into the
+steel box. In some way terrific heat and pressure are applied, and the
+diamonds are made. But how the heat and pressure are obtained is what we
+have yet to learn."
+
+He paused to watch the men at work. They were all busy, some attending
+to the machines, and others coming and going in and out of the cave. In
+one part a man was apparently getting ready a meal.
+
+Suddenly there rushed into the cave a man who seemed much excited.
+
+"Are you nearly ready with that stuff?" he cried. "There's a good storm
+gathering on the mountain!"
+
+"Yes, we'll be ready in half an hour," answered one of the men at the
+mixing machine.
+
+"Good. It will be flashing lightning bolts then, and we can see what
+luck we have. The last batch was a failure." The man hurried out again.
+Mr. Parker touched Tom and Mr. Jenks on their shoulders.
+
+"What is it?" asked Tom.
+
+"I know the secret of making the diamonds," said the scientist.
+
+"What?" cried Mr. Jenks.
+
+"It is by the awful power of the lightning bolts!" whispered Mr. Parker.
+"Everything is explained now--the reason why they make diamonds in this
+lonely place, near the top of the mountain. They need a place where the
+lightning is powerful. I can understand it now--I suspected it before.
+They make diamonds by lightning!"
+
+"Are you sure?" cried Mr. Jenks.
+
+"Positive."
+
+"I agree with you," said Tom Swift. "I was just getting on that track
+myself, when I saw the electric wires running to the steel box. That
+explains the upright rod on the top of the mountain. The man says
+a storm is coming--very well; we'll stay here and watch them make
+diamonds!"
+
+As he spoke there came the mutter of thunder, and the mountain vibrated
+slightly. The men in the cave redoubled their activity. Tom and his
+friends felt that the secret process they had so long sought was about
+to be demonstrated before their eyes.
+
+
+
+CHAPTER XXI--FLASHING GEMS
+
+
+Eagerly the adventurers looked through the opening at the end of the
+passage into the larger cave. The men opened the small oven in which the
+balls of white chemicals and carbon mixed, had been baked, and a pile of
+things, that looked like irregularly-shaped marbles, were placed in the
+steel box.
+
+This box, which was about the size of a trunk, was of massive metal. It
+was placed in a recess in the solid rock, and all about were layers of
+asbestos and other substances that were nonconductors of heat.
+
+"That box becomes red hot," exclaimed Mr. Jenks, in a whisper. "When
+things are in readiness, that lever is pulled and the diamonds are
+made. I pulled it once, but I did not then know the process involved. I
+supposed that the lightning had nothing to do with making the diamonds."
+
+"It has--a most important part," said Mr. Parker. The hidden adventurers
+could talk in perfect safety now, for the men in the large cave were too
+excited to pay much attention to them. The muttering of the thunder
+grew louder, and at times a particularly loud crash told that a bolt had
+struck somewhere in the vicinity of the cave.
+
+"But, bless my watch-charm!" exclaimed Mr. Damon, "I didn't know
+lightning made diamonds."
+
+"It does not--always," went on the scientist. "But great heat and
+pressure are necessary to create the gems. In nature this was probably
+obtained by prehistoric volcanic fires, and by the terrific pressure of
+immense rocks. It is possible to make diamonds in the laboratory of the
+chemist, but they are so minute as to be practically valueless.
+
+"However, these men seem to have hit upon a new plan. They utilize the
+terrific heat of lightning, and the pressure which is instantaneously
+obtained when the bolt strikes. I am anxious to see how it is done.
+Look, I think they are getting ready to make the gems."
+
+Indeed there seemed to be an air of expectancy among the diamond makers.
+The mixing machine had now been stopped, and, as it was more quiet
+in the cave, our friends, in their hiding-place, had to speak in mere
+whispers. All the men were now gathered about the great steel box.
+
+This receptacle had been closed by a solid metal door, which was screwed
+and clamped tight. Then one of the men examined a number of heavily
+insulated electric wires that extended from the box off into the
+darkness where Tom and his companions could not discern them.
+
+"That's Folwell--the man I befriended, and who got me into this game,"
+whispered Mr. Jenks. "He was also one of the first to turn against me. I
+think he's one of the leaders."
+
+Folwell came back, after having gone into a dark part of the cave. He
+went over to an electrical switch on one of the stone walls.
+
+"It's almost time," Tom heard him say to his confederates. "The storm is
+coming up rapidly."
+
+"Will it be severe enough?" asked one of the helpers. "We had all our
+work for nothing last time. The flashes weren't heavy enough."
+
+"These will be," asserted Folwell. "The indicator shows nearly a million
+volts now, and it's increasing."
+
+"A million volts!" exclaimed Tom. "I hope it doesn't strike anywhere
+around here."
+
+"Oh, it will probably be harmlessly conducted down on the heavy wires,"
+said Mr. Parker. "We are in no danger, at present, though ultimately I
+expect to see the whole mountain shattered by a lightning bolt."
+
+"Cheerful prospect," murmured Tom.
+
+There was a terrific crash outside. The rocky floor of the cave
+trembled.
+
+"Here she comes!" cried Folwell. "Get back, everybody! I'm going to
+throw over the switch now!"
+
+The men retreated well away from the steel box. Folwell threw over the
+lever--the same one Mr. Jenks remembered pulling. Then the man ran
+to the electric switch on the wall, and snapped that into place,
+establishing a connection.
+
+There was a moment's pause, as Folwell ran to join the others in their
+place of safety. Then from without there came a most nerve-racking and
+terrifying crash. It seemed as if the very mountain would be rent into
+fragments.
+
+Watching with eager eyes, the adventurers saw sparks flash from the
+steel box. Instantly it became red hot, and then glowed white and
+incandescent. It was almost at the melting point.
+
+Then came comparative quiet, as the echoes of the thunder died away amid
+the mountain peaks.
+
+"I guess that did the trick!" cried Folwell. "It was a terrific crash
+all right!"
+
+He and the others ran forward. The steel box was now a cherry red,
+for it was cooling. Folwell threw back the lever, and another man
+disconnected the switch. There was a period of waiting until the box was
+cool enough to open. Then the heavy door was swung back.
+
+With a long iron rod Folwell drew something from the retort. It was the
+tray which had held the white balls. But they were white no longer, for
+they had been turned into diamonds. From their hiding-place Tom and the
+others could see the flashing gems, for, in spite of the fact that the
+diamonds were uncut, some of them sparkled most brilliantly, due to the
+peculiar manner in which they were made.
+
+"We have the secret of the diamonds!" whispered Mr. Jenks. "There must
+be a quart of the gems there!"
+
+The men gathered about Folwell, uttering exclamations of delight. The
+diamonds were too hot to handle yet.
+
+"That's going some!" exclaimed the chief of the diamond makers. "We have
+a small fortune here."
+
+The was a sudden commotion at one end of the cave. A man rushed in. At
+the sight of him Tom stared and uttered an exclamation.
+
+"Munson--the stowaway!" he whispered.
+
+"Hello!" cried Folwell, as he saw his confederate. "I thought you were
+East, keeping Jenks away from here."
+
+"He got the best of me!" cried Munson, "he and that Tom Swift! I stowed
+away on their airship, but they found me out by a wireless message,
+and marooned me in the woods. I've been trying to get here ever since!
+Didn't you get my messages of warning?"
+
+"No--what warnings?" cried Folwell.
+
+"About Jenks, Tom Swift and the others. They're here--they must be on
+Phantom Mountain now. In fact, I shouldn't be surprised if they were in
+this cave. I traced them to their camp, but they're gone. They may be
+among us now--in some of the secret recesses!"
+
+For an instant Folwell stared at the bearer of these tidings. Then he
+cried out:
+
+"Scatter men, and find these fellows! We must get them before they
+discover our secret!"
+
+"It's too late--we know it!" exulted Tom Swift. Then he whispered to
+the others to hurry to the part of the cave where Bill Renshaw had first
+hidden them.
+
+
+
+
+CHAPTER XXII--PRISONERS
+
+
+"Do you think there is any danger of them finding us?" asked Mr. Damon,
+as he hurried along beside Tom.
+
+"I'm afraid so," was the answer. "I've been worried ever since we saw
+Munson heading this way. But we couldn't do any differently."
+
+"Perhaps Bill Renshaw may be able to conceal us," suggested Mr. Jenks.
+"Very likely he knows that Munson is on hand. Perhaps we will be safe
+for a while. I want to make a few more observations as to how they
+manufacture the diamonds, and then, with what I already know, I'll have
+the secret."
+
+"And I'd like to make some scientific tests of the sides and bottom
+rocks of the cave," spoke Mr. Parker. "I think it will bear out my
+theory that the mountain will soon be destroyed."
+
+"Well, you were right about Earthquake Island, and you may be right
+about this mountain," said Tom, "but if it is going to be annihilated I
+hope we get far enough away from it."
+
+"We can keep our presence here a secret for a few more days, I think
+that will be long enough," proceeded Mr. Jenks. "Then we will leave."
+
+"And, in the meanwhile, they'll be searching for us," objected Mr.
+Damon. "I wish that ghost-chap would come back and tell us what to do.
+Bless my liver-pin, but we are going to be in considerable danger, I'm
+afraid! Those men may capture us, and decide to make diamond dust from
+us."
+
+"Come on--hurry to the little cave," urged Tom. "Then we'll get ready to
+defend ourselves."
+
+"The main cave is a large one," said Mr. Jenks, "and there are many
+hiding places in it. In fact, it is so large that it will take those
+fellows several days to complete a circuit of it. By that time Bill
+Renshaw may come back, and take us to some place in which they have
+already searched for us. Then we'll be comparatively safe."
+
+This thought was some consolation to them, as they made their way
+through the dark passage, dimly illuminated by the lantern they had
+rekindled, to the place where Bill had hidden them. They found things
+as they had left them, and proceeded to get a meal, though Tom said it
+would be best not to cook anything, or even to make coffee, for fear the
+odors would enable the searchers to trail them.
+
+So they ate cold food, glad to get that. Silently they sat about the
+dimly-lighted cavern, and discussed the situation. True they might even
+now retreat, going out of the entrance Bill had showed them, and so
+escape. But Mr. Jenks felt that his mission was not completed yet, and
+they all agreed to stay with him.
+
+"For there are several points about making diamonds that are not
+quite clear to me," he said. "I need to know how that steel box is
+constructed, how the electrical switches are arranged, what kind of
+lightning rods they use, and how they regulate the pressure. The other
+things, and how to mix the ingredients, I already know."
+
+"Then we'll do our best to help you," promised Tom. "But now I think we
+had better see what sort of a defense we can put up. We have our guns
+and revolvers, and with these chairs and tables we can build a sort of
+barricade behind which we can take refuge if those fellows do discover
+our hiding place."
+
+This was conceded to be a good idea, and soon a rude sort of fort was
+made, behind which the adventurers could take their stand and fight, if
+necessary, though they hoped this would not come to pass.
+
+They remained quietly in the cave the remainder of that day, and, when
+it was night, as they could tell by their timepieces--there was no
+daylight--they divided the hours into watches, taking turns standing
+guard.
+
+Morning, at least in point of time, came without any disturbance, and
+they made a cold breakfast. They hoped that Bill Renshaw would come, but
+he did not appear.
+
+After sitting in the dark cave until afternoon, Tom said:
+
+"I think we might as well go and take another observation of the big
+cave. We can tell what the men are doing, then, for they don't seem to
+have been near us. Maybe they have given up the search for us, and we
+can see them at work, and Mr. Jenks can gain what further knowledge he
+needs."
+
+"That will be a good plan," agreed the diamond man. "It's maddening to
+sit here, doing nothing."
+
+"And it will be comparatively safe to go from here to our former post of
+observation," added Tom, "for there doesn't seem to be any opening along
+the tunnel, into the larger cave, except the place where we were."
+
+Accordingly they started off. Cautiously they looked through the opening
+into the apartment where they had seen the diamonds made.
+
+"There's not a soul here!" exclaimed Tom, in a whisper. The others
+looked. The place was deserted--the machinery silent. Mr. Jenks peered
+in for a moment, and then exclaimed:
+
+"I'm going in! Now's my chance to find out all that I wish to know! It
+may never come again, and then we can soon leave Phantom Mountain!"
+
+It was a daring plan, but it seemed to be the best one to follow. They
+were all tired of inactivity. Mr. Jenks managed to get through the
+opening, and dropped into the big cave. The others followed. Mr. Jenks
+hurried over to the steel box, and began an examination of it. Tom Swift
+was looking at the electrical switch. He saw how it was constructed. Mr.
+Damon and Mr. Parker were peering interestedly about.
+
+Suddenly the sound of voices was heard, and the echo of footsteps. Mr.
+Jenks started.
+
+"They're coming back!" he whispered hoarsely. "Run!"
+
+They all turned and sped toward their hiding place. But they were too
+late. An instant later Folwell, Munson and the other diamond makers
+confronted them. Our friends made a bold rush, but were caught before
+they could go ten feet.
+
+"We have them!" cried Munson. "They walked right into our hands!"
+
+It was true. Tom Swift and the others were the prisoners of the diamond
+makers.
+
+
+
+CHAPTER XXIII--BROKEN BONDS
+
+
+"Well," remarked Tom Swift, in mournful tones, "this looks as if we were
+up against it; doesn't it?"
+
+"Bless my umbrella, it certainly does," agreed Mr. Damon.
+
+"And it's all my fault," said Mr. Jenks. "I shouldn't have gone into the
+big cave. I might have known those men would come back any time."
+
+The above conversation took place as our friends lay securely bound in
+a small cave, or recess, opening from the larger cavern, where, about
+an hour before, they had been captured and made prisoners by the diamond
+makers. Despite their struggles they had been overpowered and bound,
+being carried to the cave, where they were laid in a row on some old
+bags.
+
+"It certainly is a most unpleasant situation, to say the least,"
+observed Mr. Parker.
+
+"And all my fault," repeated Mr. Jenks.
+
+"Oh, no it isn't," declared Tom Swift, quickly. "We were just as ready
+to follow you into that cave as you were to go. No one could tell that
+the men would return so soon. It's nobody's fault. It's just our bad
+luck."
+
+From where he lay, tied hand and foot, the young inventor could look
+out into the cave where he and the others had been caught. The diamond
+makers were busily engaged, apparently in getting ready to manufacture
+another batch of the precious stones. They paid little attention to
+their captives, save to warn them, when they had first been taken into
+the little cave, that it was useless to try to escape.
+
+"They needn't have told us that," observed Tom, as he and the others
+were talking over their situation in low voices. "I don't believe any
+one could loosen these ropes."
+
+"They certainly are pretty tight," agreed Mr. Damon. "I've been tugging
+and straining at mine for the last half hour, and all I've succeeded in
+doing is to make the cords cut into my flesh."
+
+"Better give it up," advised Mr. Jenks.
+
+"We'll just have to wait."
+
+"For what?" the scientist wanted to know.
+
+"To see what they'll do with us. They can't keep us here forever.
+They'll have to let us go some time." Following their capture, Folwell
+and Munson, the latter the stowaway of the airship, had been in earnest
+conversation regarding our friends, but what conclusion they had reached
+the adventurers could only guess.
+
+"And we didn't have time to examine the diamond-making machinery close
+enough so that we could duplicate it if necessary," complained Tom, a
+little later.
+
+"No," agreed Mr. Jenks. "There are certain things about it that are not
+clear to me. Well, I don't believe I'll have another chance to inspect
+it. They'll take good care of that, though they seem to be getting ready
+to make more diamonds."
+
+"Perhaps they're going to manufacture a big batch, and then leave this
+place," suggested Mr. Damon. "They will probably go to some other secret
+cave, and leave us here."
+
+"I hope they untie us before they leave, and give us something to eat,"
+remarked the young inventor.
+
+For two hours longer the captives lay there, in most uncomfortable
+positions. Then Folwell and Munson, leaving the group of diamond makers
+who were grouped about the machinery, approached the captives.
+
+"Well," remarked Munson, "we got ahead of you after all; didn't we. You
+thought you had our secret, but it will be a long while before you ever
+make diamonds."
+
+"What are you going to do with us?" asked Tom.
+
+"Never mind. You came where you had no right to, and you must take the
+consequences."
+
+"We did have a right to come here!" exclaimed Mr. Jenks. "I am entitled
+to know how the diamonds are made. I paid for the information, and you
+tricked me. If ever it's possible I'll have the whole gang arrested for
+swindling."
+
+"You'll never get the chance!" declared Folwell. "You were given some
+diamonds for the money you invested, and that makes us square."
+
+"No, it doesn't!" declared Mr. Jenks. "I invested the money to learn how
+to make diamonds, and you know it! You tricked me, and I had a right
+to try to discover your secret! I nearly have it, too, and I'll get it
+completely before I'm done with you!"
+
+"No, you won't!" boasted Folwell. "But we didn't come here to tell you
+that. We came to give you something to eat. We're not savages and
+we'll treat you as well as we can in spite of the fact that you are
+trespassers. We're going to give you some grub, but I warn you that any
+attempt to escape will mean that some of you will get hurt."
+
+He signalled to some of his confederates. These men unbound the
+captives' arms, and stood over them while they ate some coarse food that
+was brought into the small cave. They were given coffee to drink, and
+then, when the simple meal was over, they were securely bound again,
+and left to themselves, while the diamond makers went back to their
+machinery.
+
+It was evident that they were going to attempt a big operation, for an
+unusually large quantity of the white stuff was prepared. The prisoners
+watched them idly. They could see some but not all of the operations. In
+this way several hours passed.
+
+Gloom possessed the hearts of Tom and his friends. Not only had their
+expedition been almost a failure so far, but the young inventor was
+worried lest the gang might discover and wreck his airship. This would
+prove a serious loss. Lying there in the semi-darkness the lad imagined
+all sorts of unpleasant happenings.
+
+At times he dozed off, as did the others. They had become somewhat used
+to the pain caused by the bonds, for their nerves were numb from the
+strain and pressure.
+
+Once, as he was lightly sleeping, Tom was awakened by hearing loud
+voices in the main cave. He looked out, rolling over slightly to get a
+better view. He saw the man who, once before had run in to give news of
+an approaching electrical storm.
+
+"Are you fellows all ready?" asked this same man again.
+
+"Yes. Is there another storm coming?"
+
+"Yes, and it's going to be a corker!" was the reply. "It's one of the
+worst I've ever seen. It's sweeping right up the valley. It'll be here
+in an hour."
+
+"That's good. We need a big flash to make all the material we have
+prepared into diamonds. It's the biggest batch we ever tried. I hope it
+succeeds, for we're going to leave--" The rest was in so low a tone that
+Tom could not catch it.
+
+The storm messenger departed. Folwell and Munson busied themselves about
+the machinery. Tom dozed off again, dimly wondering what had become of
+Bill Renshaw, and whether the former ghost knew of their plight. The
+others were asleep, as the young inventor saw by the dim light of a
+lantern in the cave. Then, he too, shut his eyes.
+
+Tom was suddenly awakened by feeling some one's hands moving about his
+clothing. At first he thought it was one of the diamond-making gang, who
+had sneaked in to rob him. "Here! What are you up to?" exclaimed Tom.
+
+"Quiet!" cautioned a voice. "Are you all here?"
+
+"All of us--yes. But who are you?"
+
+"Easy--keep quiet, Tom Swift! I'm Bill Renshaw! I've been searching all
+over for you, since I got back to your cave and found it empty. Now I'm
+going to free you. I got in here by a secret entrance. Wait, I'll cut
+your ropes." There was a slight sound, and an instant later Tom was
+freed from his bonds.
+
+
+
+
+CHAPTER XXIV--IN GREAT PERIL
+
+
+The young inventor could scarcely believe the good luck that had so
+unexpectedly come to him and his companions. No sooner was Tom able to
+move freely about than Bill Renshaw performed the same service for Mr.
+Jenks and the others, cautioning them to be quiet as he awakened them,
+and cut the ropes.
+
+"Bless my circulation!" exclaimed Mr. Damon, in a hoarse whisper. "How
+did you ever get here. I'd given ourselves up for lost."
+
+"Oh, I came in off the mountain, as there's a big storm due," explained
+the man. "There was no need of me playing the haunt in daytime, anyhow.
+I went to the cave, found you and your things gone, and I surmised that
+you might have walked into some trap."
+
+"We did," admitted Mr. Jenks, grimly.
+
+"Well, I hunted around until I found you," went on Bill. "This mountain
+is honeycombed with caves, all opening from the large one, I know them
+better than these fellows do, so I could explore freely, and keep out of
+their sight. They didn't know that there was a second entrance to this
+place, but I did, and I made for it, when I couldn't find you in some of
+the other caves where I looked. And, sure enough, here you were."
+
+"Well, we can't thank you enough," said Mr. Parker. "But you say there
+is a big storm coming?"
+
+"One of the biggest that's been around these parts in some time,"
+replied Bill.
+
+"Then perhaps the mountain will be destroyed," went on the scientist, as
+calmly as if he had remarked that it might rain.
+
+"I hope nothing like that happens until we get away," spoke Mr. Damon,
+fervently.
+
+"What had we better do?" inquired Tom.
+
+"Get away, unless you want to discover some more of their secrets,"
+advised Bill. "Those fellows are planning something, but I can't find
+out what it is. They are suspicious of me, I think. But they are up to
+something, and I believe, it would be best for you to leave while you
+have the chance. It may not be healthy to stay. That's why I did my best
+to untie you."
+
+"We appreciate what you have done," declared Mr. Jenks, "but I want my
+rights. I must learn a few more facts about how to make diamonds from
+lightning flashes, and then I will have the same secret they cheated me
+out of. I think if we wait a while we may be able to see the parts of
+the process that are not quite clear to us. What do you say, Tom Swift?"
+
+"Well, I would like to learn the secret," replied the lad, "and if Bill
+thinks it's safe to stay here a while longer--"
+
+"Oh, I guess it will be safe enough," was the reply. "Those fellows
+won't bother about you now that they are about to make some more
+diamonds. Besides, they think you're all tied up. Yes, you can stay here
+and watch, I reckon. I've got a couple of guns, and--"
+
+"Then we'll stay," decided Tom. "We can put up a better fight now."
+
+Silently, in their prison, but which they could now leave whenever they
+pleased, the adventurers watched the diamond makers once more. The same
+process they had witnessed before was gone through with. The white balls
+were put inside the steel box and sealed up. Then they waited for the
+storm to reach its height.
+
+That this would not be long was evidenced by the mutterings of thunder
+which every moment grew louder. The outburst of electrical fury was
+likely to take place momentarily, and that it would be unusually severe
+was shown by the precautions taken by the diamond makers. They attached
+a number of extra wires, and brought out some insulated, hard rubber
+platforms, on which they themselves stood. Tom and Mr. Jenks were much
+interested in watching this detail of the work, and sought to learn how
+each part of the process was done.
+
+"I almost think we can make diamonds, Tom, when we get back to
+civilization," whispered Mr. Jenks.
+
+"I hope we can," answered Tom, "and we can't get back any too soon to
+suit me. I want to be in my airship again."
+
+"I don't blame you. But look, they are getting ready to adjust the
+switch."
+
+The adventurers ceased their whispered talk, and eagerly watched the
+diamond makers. Folwell and Munson were hurrying to and fro in the big
+cave, attending to the adjustments of the machinery.
+
+"On your insulated plates--all of you," Folwell gave the order. "This
+is going to be a terrific storm. The gage shows twice the power we have
+ever used, and it's creeping up every minute! We'll have more diamonds
+than ever had before!"
+
+"Yes, if the mountain isn't destroyed," added Mr. Parker, in a low
+voice. "I predict that it will be split from top to bottom!"
+
+"Comforting," thought Tom, grimly.
+
+"I guess we're all ready," said Folwell, in a low tone to Munson. "We'd
+better get insulated ourselves. I'm going to throw the switch."
+
+He did so. A moment later the man who had before given warning of the
+storm came dashing in. He was very much excited.
+
+"It's awful!" he cried. "The lightning is striking all over! Big rocks
+are being split like logs of wood!"
+
+"Well, it can't do any damage in here," said Munson. "We are well
+protected. Get on one of the plates," and he motioned to one of the
+hard-rubber platforms that was not occupied. The roar and rumble of the
+storm outside had given place to short terrific crashes. In their small
+cave the adventurers could feel the solid ground shake.
+
+A bluish light began dancing about the electrical wires. There was a
+smell of sulphur in the air. Crash after crash resounded outside. A
+flash of flame lit up the whole interior of the cave. It came from the
+copper switch.
+
+"Something's wrong with the insulation!" cried Munson.
+
+"Don't go near it!" yelled Folwell. "If you value your life, stand
+still!"
+
+Hardly had he spoken than inside the cavern there sounded a report like
+that of a small cannon. A big ball of fire danced about the middle of
+the cave and then leaped on top of the steel box.
+
+"This is a fearful storm," cried Munson.
+
+The adventurers in the cave did not know what to say or do. They were in
+deadly peril.
+
+Suddenly there came a crash louder than any that had preceded it. The
+whole side of the cave where the switches were was a mass of bluish
+flame. Then came a ripping, tearing sound, and a tangle of wires and
+copper connections were thrown to the floor. At the same time the steel
+box, containing the materials from which diamonds were made, turned
+blue, and flames shot from it.
+
+"It's all up with us!" cried Munson. "Run for it, everybody! The wires
+are down, and this place will be an electric furnace in another minute!"
+
+He leaped toward the exit from the cave.
+
+"What about those fellows?" asked Folwell, indicating the place where
+Tom and the others had been tied.
+
+"They'll have to do the best they can! It's every man for himself, now!"
+yelled Munson. There was a wild scramble from the cavern.
+
+"Come on!" cried Tom. "We must escape! It's our only chance!"
+
+He leaped into the big cave, followed by the others. Already long
+tongues of electrical fire were shooting out from the walls and roof as
+Tom Swift and his companions, evading them as best they could, sought
+safety in flight.
+
+
+
+CHAPTER XXV--THE MOUNTAIN SHATTERED--CONCLUSION
+
+
+"Can't we get some of the diamonds?" cried Mr. Damon, as he raced along
+behind Tom. "Now's our chance. Those fellows have all gone!" The odd man
+made a grab for something as he ran.
+
+"It's as much as our lives are worth," declared the young inventor. "We
+dare not stop! Come on!"
+
+"I'd like to investigate some of the machinery," spoke Mr. Jenks, "but I
+wouldn't stop, even for that."
+
+"The storm is too dangerous," called Bill Renshaw. "I can show you a
+shorter way out than the one those fellows have taken. Follow me."
+
+"No way can be too short," said Mr. Parker, solemnly. "This mountain
+will go to pieces shortly, I think!"
+
+Tom shuddered. He remembered how narrow had been their escape when
+Earthquake Island sank into the sea. And that some terrific upheaval was
+now imminent might be judged from the awful reports that sounded more
+plainly as the adventurers raced toward the opening of the cave. It was
+like the bombardment of some doomed city.
+
+Mr. Jenks and Tom cast one longing look behind at the complicated and
+expensive machinery that had been installed in the cave by the diamond
+makers. They had abandoned it, and in it lay the secret of making
+precious gems. But there was no time to stop now, and investigate.
+
+"This way," urged Bill Renshaw. "We'll soon be out."
+
+"But won't it be dangerous to go outside?" asked Mr. Damon. "Shan't we
+be struck by lightning? There is some protection in here."
+
+"None at all," said Mr. Parker, quickly. "This mountain is a natural
+lightning rod. To stay here in this cave will be sure death when the
+storm gets directly over it. And that will be very soon. We must get
+on insulated ground. Is there any part of this mountain that does not
+contain iron ore?" the scientist asked of the former spirit.
+
+"Yes; the way out by which we are going lands on a dirt hill."
+
+"That's good; then we may be saved."
+
+On they ran. They had no lanterns, but the blue light of the
+electricity, as it leaped from point to point inside the cave, where
+there were outcroppings of iron ore, made the place bright enough to
+see.
+
+"Here we are!" cried Bill Renshaw at length. "Here's the way out!"
+
+Making a sudden turn in the winding passage he showed the adventurers
+a small opening in the side of the crag. In an instant they had passed
+through, and found themselves in daylight once more. The sudden glare
+almost blinded them, for, though the sky was overcast by clouds, from
+which jagged tongues of lightning played, the outside was much lighter
+than the dark cave.
+
+"I should say it was a storm!" cried Tom Swift. "See, it is striking
+every minute, and all around us!"
+
+In fact, lightning bolts were falling on every side of the adventurers.
+Every time the balls of fire struck, they burst open great stones,
+or seared a livid scar on the face of some cliff. As for Tom and the
+others, they stood on a dry dirt hill, in which, fortunately, there was
+no iron ore. To this fact they undoubtedly owed their lives, though
+had there been rain, to moisten the ground and make the earth a good
+conductor of electricity, they probably would have been badly shocked.
+But the electrical outburst was not accompanied by rain.
+
+Tom looked up. He saw a compact mass of cloud moving toward the summit
+of the mountain on the slope of which they stood. From this cloud there
+played shafts of reddish-green fire.
+
+"Look!" called the young inventor to Mr. Parker. The instant the latter
+saw the cloud, he cried:
+
+"We must get away from here by all means! That is the center of the
+storm. As soon as it gets over the mountain, where that lightning rod
+is, all the electrical fluid will be discharged in one bolt at the
+mountain, and it will be destroyed! We must run, but keep on the dirt
+places! Run for your lives!"
+
+They needed no second warning. Turning, they fled down the steep side of
+the mountain, slipping and stumbling, but taking care not to step on any
+iron ore. Behind them flashed the lightning bolts.
+
+Suddenly there was a most awful crash. It seemed as if the end of the
+world had come, and the ear drums of Tom and his companion almost burst
+with the fearful report. The concussion knocked them down, and they lay
+stunned for a moment.
+
+Following the terrible report there was a low, rumbling sound. Hardly
+knowing whether he was dead or alive, Tom opened his eyes and looked
+about him. What he saw caused him to cry out in terror.
+
+The whole mountain seemed bathed in fire. Great blue, red and green
+flashes played around it. Then the towering cliff seemed to melt and
+crumble up, and the great peak, the top of it containing the diamond
+makers' cave, from which they had fled but a few minutes before, the
+entire summit was toppled over into the valley on the other side, and in
+the direction opposite to that where the adventurers stood.
+
+Then came a profound silence, and the lightning ceased. The storm was
+over, and only the rattle of stones and boulders, as they came to rest
+in the valley below, reached the ears of our friends.
+
+"Phantom Mountain has been destroyed, just as I said it would be," spoke
+Mr. Parker, solemnly. Once more he had prophesied correctly.
+
+For a few minutes the adventurers hardly knew what to say. They arose
+awkwardly from the ground where the shock had tossed them. Then Tom
+remarked, as calmly as possible:
+
+"Well, it's all over. I guess we may as well get back to our airship."
+
+"What became of Munson and the others?" asked Mr. Damon.
+
+Mr. Jenks pointed to the trail, far below. The figures of some men,
+running madly, could be seen.
+
+"There they go," he said; "I fancy we have seen the last of them." And
+they had, for some time at least.
+
+There was little use lingering any longer on Phantom Mountain--indeed
+little of it was left on which to remain. Looking back toward the place
+where the cave had been, Tom and the others started forward again.
+The diamond-making machinery had all been destroyed. So, also, had the
+finished diamonds stored in the cavern and the large supply which had
+probably been made by the last terrific crash. No one would ever have
+them now. Tom and Mr. Jenks felt a sense of disappointment, but they
+were glad to have escaped with their lives. They sought their former
+camp, but the tent and all their food was buried under tons of earth and
+rocks.
+
+Three days later, after rather severe hardships, they were near the
+place where they had left the Red Cloud. They had suffered cold and
+hunger, for they had no food supplies, and, had it not been that Bill
+Renshaw knew the haunts of some game, of which they managed to snare
+some, they would have fared badly, for they had left their guns in the
+cave.
+
+"Well, there are the trees behind which I hope my airship is hidden,"
+announced Tom, as they came to the spot. "Good old Red Cloud! Maybe we
+won't do some eating when we get aboard, eh?"
+
+"Bless my appetite! but we certainly will!" cried Mr. Damon.
+
+"There's somebody walking around the place," spoke Mr. Jenks.
+
+"I hope it's no one who has damaged the ship," came from Tom,
+apprehensively. He broke into a run, and soon confronted an aged miner,
+who seemed to have established a rude sort of camp near the airship.
+
+"Is anything the matter?" asked Tom, breathlessly. "Is my airship all
+right?"
+
+"I guess she's all right, stranger," was the reply. "I don't know much
+about these contraptions, but I haven't touched her. I knowed she was an
+airship, for I've seen pictures of 'em, and I've been waiting until the
+owner came along."
+
+"Why?" asked Tom, wonderingly.
+
+"Because I've got a proposition to make to you," went on the miner, who
+said his name was Abe Abercrombie. "I've been a miner for a good many
+years, and I'm just back from Alaska, prospecting around here. I haven't
+had any luck, but I know of a gold mine in Alaska that will make us all
+rich. Only it needs an airship to get to it, and I've been figuring how
+to hire one. Then I comes along, and I sees this big one, and I makes up
+my mind to stay here until the owners come back. That's what I've done.
+Now, if I prove that I'm telling the truth, will you go to Alaska--to
+the valley of gold with me?"
+
+"I don't know," answered Tom, to whom the proposition was rather sudden.
+"We've just had some pretty startling adventures, and we're almost
+starved. Wait until we get something to eat, and we'll talk. Come aboard
+the Red Cloud," and the lad led the way to his craft which was in as
+good condition as when he left it to go to the diamond cave. Later he
+listened to the miner's story.
+
+Tom Swift did go to the valley of gold in Alaska, and what happened to
+him and his companions there will be told of in the next volume of this
+series, to be called "Tom Swift in the Caves of Ice; or, the Wreck of
+the Airship."
+
+It did not take our friends long, after they had eaten a hearty meal,
+to generate some fresh gas, and start the Red Cloud on her homeward way.
+Tom wanted to take Bill Renshaw with him, but the old man said he would
+rather remain among the mountains where he had been born. So, after
+paying him well for his services, they said good-by to him. Abercrombie,
+the miner, also remained behind, but promised to call and see Tom in a
+few months.
+
+"Well, we didn't make any money out of this trip," observed Mr. Jenks,
+rather dubiously, as they were nearing Shopton, after an uneventful
+trip. "I guess I owe you considerable, Tom Swift. I promised to get you
+a lot of diamonds, but all I have are those I had from my first visit to
+the cave."
+
+"Oh, that's all right," spoke Tom, easily. "The experience was worth all
+the trip cost."
+
+"Speaking of diamonds, look here!" exclaimed Mr. Damon, suddenly, and he
+pulled out a double handful.
+
+"Where did you get them?" cried the others in astonishment.
+
+"I grabbed them up, as we ran from the cave," said the eccentric man;
+"but, bless my gaiters! I forgot all about them until you spoke. We'll
+share them."
+
+These diamonds, some of which were large, proved very valuable, though
+the total sum was far below what Mr. Jenks hoped to make when he started
+on the remarkable trip. Tom gave Mary Nestor a very fine stone, and it
+was set in a ring, instead of a pin, this time.
+
+On their arrival in Shopton, where Mr. Swift, the housekeeper, Mr.
+Jackson and Eradicate Sampson were much alarmed for Tom's safety, an
+attempt was made to manufacture diamonds, using a powerful electric
+current instead of lightning. But it was not a success, and so Mr. Jenks
+concluded to give up his search for the secret which was lost on Phantom
+Mountain.
+
+And now we will take leave of Tom Swift, to meet him again soon in other
+adventures he is destined to have in the caves of ice and the valley of
+gold.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+Project Gutenberg's Etext of Tom Swift Among the Diamond Makers
+*****This file should be named 07tom10.txt or 07tom10.zip******
+
+Corrected EDITIONS of our etexts get a new NUMBER, 07tom11.txt.
+VERSIONS based on separate sources get new LETTER, 07tom10a.txt.
+
+
+This Etext was prepared for Project Gutenberg by Anthony Matonac.
+
+
+We are now trying to release all our books one month in advance
+of the official release dates, for time for better editing.
+
+Please note: neither this list nor its contents are final till
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg Etexts is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so. To be sure you have an
+up to date first edition [xxxxx10x.xxx] please check file sizes
+in the first week of the next month. Since our ftp program has
+a bug in it that scrambles the date [tried to fix and failed] a
+look at the file size will have to do, but we will try to see a
+new copy has at least one byte more or less.
+
+
+Information about Project Gutenberg (one page)
+
+We produce about two million dollars for each hour we work. The
+fifty hours is one conservative estimate for how long it we take
+to get any etext selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. This
+projected audience is one hundred million readers. If our value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour this year as we release thirty-two text
+files per month: or 400 more Etexts in 1996 for a total of 800.
+If these reach just 10% of the computerized population, then the
+total should reach 80 billion Etexts.
+
+The Goal of Project Gutenberg is to Give Away One Trillion Etext
+Files by the December 31, 2001. [10,000 x 100,000,000=Trillion]
+This is ten thousand titles each to one hundred million readers,
+which is only 10% of the present number of computer users. 2001
+should have at least twice as many computer users as that, so it
+will require us reaching less than 5% of the users in 2001.

+CHAPTER I--A SUSPICIOUS JEWELER
+
+
+"Well, Tom Swift, I don't believe you will make any mistake if
+you buy that diamond," said the jeweler to a young man who was
+inspecting a tray of pins, set with the sparkling stones. "It is
+of the first water, and without a flaw."
+
+"It certainly seems so, Mr. Track. I don't know much about
+diamonds, and I'm depending on you. But this one looks to be all
+right."
+
+"Is it for yourself, Tom?"
+
+"Er--no--that is, not exactly," and Tom Swift, the young
+inventor of airships and submarines, blushed slightly.
+
+"Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I
+think she would like a pin of this sort. True, it's rather
+expensive, but--"
+
+"No, it isn't for Mrs. Baggert, Mr. Track," and Tom seemed a
+bit embarrassed.
+
+"No? Well, then, Tom--of course it's none of my affair, except
+to sell you a good stone, But if this brooch is for a young lady,
+I can't recommend anything nicer. Do you think you will take
+this; or do you prefer to look at some others?"
+
+"Oh, I think this will do, Mr. Track. I guess I'll take--"
+
+Tom's Words were interrupted by a sudden action on the part of
+the jeweler. Mr. Track ran from behind the showcase and hastened
+toward the front door.
+
+"Did you see him, Tom?" he cried. "I wonder which way he went?"
+
+"Who?" asked the lad, following the shopkeeper.
+
+"That man. He's been walking up and down in front of my place
+for the last ten minutes--ever since you've been in here, in
+fact, and I don't like his looks."
+
+"What did he do?"
+
+"Nothing much, except to stare in here as if he was sizing my
+place up."
+
+"Sizing it up?"
+
+"Yes. Getting the lay of the land, so he or some confederate
+could commit a robbery, maybe."
+
+"A robbery? Do you think that man was a thief?"
+
+"I don't know that he was, Tom, and yet a jeweler has to be
+always on the watch, and that isn't a joke, either, Tom Swift.
+Swindlers and thieves are always on the alert for a chance to rob
+a jewelry store, and they work many games."
+
+"I didn't notice any particular man looking in here," said Tom,
+who still held the diamond brooch in his hand.
+
+"Well I did," went on the jeweler. "I happened to glance out of
+the window when you were looking at the pins, and I saw his eyes
+staring in here in a suspicious manner. He may have a confederate
+with him, and, when you're gone, one may come in, and pretend to
+want to look at some diamonds. Then, when I'm showing him some,
+the other man will enter, engage my attention, and the first man
+will slip out with a diamond ring or pin. It's often done."
+
+"You seem to have it all worked out, Mr. Track," observed the
+lad, with a smile. "How do you know but what I'm in with a gang
+of thieves, and that I'm only pretending to want to buy a diamond
+pin?"
+
+"Oh, I guess I haven't known you, Tom Swift, ever since you
+were big enough to toddle, not to be sure about what you're up
+to. But I certainly didn't like the looks of that man. However,
+let's forget about him. He seems to have gone down the street,
+and, after all, perhaps I was mistaken. Just wait until I show
+you a few more styles before you decide. The young lady may like
+one of these," and the jeweler went to another showcase and took
+out some more trays of brooches.
+
+"What makes you think she's a young lady, Mr. Track?" asked the
+lad.
+
+"Oh, it's easy guessing, Tom. We jewelers are good readers of
+character. I can size up a young fellow coming in here to buy an
+engagement or a wedding ring, as soon as he enters the door. I
+suppose you'll soon be in the market for one of those, Tom, if
+all the reports I hear about you are true--you and a certain Mary
+Nestor."
+
+"I--er--I think I don't care for any of these pins," spoke Tom,
+quickly, with a blush. "I like the first lot best. I think I'll
+take the one I had in my hand when that man alarmed you. Ha!
+That's odd! What did I do with it?"
+
+Tom looked about on the showcase, and glanced down on the
+floor. He had mislaid the brooch, but the jeweler, with a laugh,
+lifted it out of a tray a moment later.
+
+"I saw you lay it down," he said. "We jewelers have to be on
+the watch. Here it is. I'll just put it in a box, and--"
+
+With an exclamation, Mr. Track gave a hasty glance toward his
+big show window. Tom looked up, and saw a man's face peering in.
+At the sight of it, he, too, uttered a cry of surprise.
+
+The next instant the man outside knocked on the glass,
+apparently with a piece of metal, making a sharp sound. As soon
+as he heard it, the jeweler once more sprang from behind the
+showcase, and leaped for the door crying:
+
+"There's the thief! He's trying to cut a hole through my show
+window and reach in and get something! It's an old trick. I'll
+get the police! Tom, you stay here on guard!" and before the lad
+could utter a protest, the jeweler had opened the door, and was
+speeding down the street in the gathering darkness.
+
+Tom stared about him in some bewilderment. He was left alone in
+charge of a very valuable stock of jewelry, the owner of which
+was racing after a supposed thief, crying:
+
+"Police! Help! Thieves! Stop him, somebody!"
+
+"This is a queer go," mused Tom. "I wonder who that man was? He
+looked like somebody I know, and yet I can't seem to place his
+face. I wonder if he was trying to rob the placer Maybe there's
+another one--a confederate--around here."
+
+This thought rather alarmed Tom, so he went to the door, and
+looked up and down the street. He could see no suspicious
+characters, but in the direction in which the jeweler was running
+there was a little throng of people, following Mr. Track after
+the man who had knocked on the window.
+
+"I wish I was there, instead of here," mused the lad. "Still I
+can't leave, or a thief might come in. Perhaps that was the game,
+and one of the gang is hanging around, hoping the store will be
+deserted, so he can enter and take what he likes."
+
+Tom had read of such cases, and he at once resolved that he
+would not only remain in the jewelry shop, but that he would lock
+the door, which he at once proceeded to do. Then he breathed
+easier.
+
+The town of Shopton, in the outskirts of which Tom lived with
+his father, and where the scene above narrated took place, was
+none too well lighted at night, and the lad had his doubts about
+the jeweler catching the oddly-acting man, especially as the
+latter had a good start.
+
+"But some one may head him off," reasoned Tom. "Though if they
+do catch him, I don't see what they can prove against him. Hello,
+here I am carrying this diamond pin around. I might lose it.
+Guess I'll put it back on the tray."
+
+He replaced in the proper receptacle one of the pins he bad
+been examining when the excitement occurred.
+
+"I wonder if Mary will like that?" he said, softly. "I hope she
+does. Perhaps it would be better if she could come here herself
+and pick out one--"
+
+Tom's musing was suddenly interrupted by a sharp tattoo on the
+glass door of the jewelry shop. With a start, he looked up, to
+see staring in on him the face of the man who had been there
+before--the man of whom the jeweler was even then in chase.
+
+"Why--why----" stammered Tom.
+
+The man knocked again.
+
+"Tom--Tom Swift!" he called. "Don't you know me?"
+
+"Know you--you?" repeated the lad.
+
+"Yes--don't you remember Earthquake Island--how we were nearly
+killed there--don't you remember Mr. Jenks?"
+
+"Mr. Jenks?"
+
+Tom was so startled that he could only repeat words after the
+strange man, who was talking to him from outside the glass door.
+
+"Yes, Mr. Jenks," was the reply. "Mr. Barcoe Jenks, who makes
+diamonds. I saw you in the store about to buy a diamond--I wanted
+to tell you not to--I'll give you a better diamond than you can
+buy--I just arrived in this place--I must have a private talk
+with you--Come out--I'll share a wonderful secret with you."
+
+A flood of memory came to Tom. He did recall the very strange
+man who walked around Earthquake Island--where Tom and some
+friends had been marooned recently--walked about with a pocketful
+of what he said were diamonds. Now Barcoe Jenks was here.
+
+"I must see you privately, Tom Swift," went on Mr. Jenks, as he
+once more tapped on the glass. "Don't waste money buying
+diamonds, when you and I can make better ones. Where can I have a
+talk with you? I--" Mr. Jenks suddenly looked down the dimly-lighted
+street. "They're coming back!" he cried. "I don't want to
+be seen. I'll call at your house later to-night--be on the watch
+for me--until then--good-by!"
+
+He waved his hand, and was gone in an instant. Tom stood
+staring at the glass door. He hardly knew whether to believe it
+or not--perhaps it was all a dream.
+
+He pinched himself to make sure that he was awake. Very
+substantial flesh met his thumb and finger, and he felt the pain.
+
+"I'm awake all right," he murmured. "But Barcoe Jenks here--and
+still talking that nonsense about his manufactured diamonds. I
+think he must be crazy. I wonder--"
+
+Once more the lad's musing was interrupted. He heard a murmur
+of excited voices outside the store, on the street. Then the door
+of the jewelry shop was tried. Mr. Track's face was pressed
+against the glass.
+
+"Open the door! Let me in, Tom!" he called. "I've caught the
+thief," and as the lad unlocked the portal he saw that the
+jeweler held by the arm a ragged lad. "Ah; you scoundrel! I've
+caught you!" cried the diamond merchant, shaking the small chap,
+while Tom looked on, more mystified than ever.
+
+
+
+
+CHAPTER II--A MIDNIGHT VISIT
+
+
+While Mr. Track, the jeweler, and several citizens, attracted
+by the chase after the supposed thief, are crowded into the
+store, anxious to hear explanations of the strange affair, I will
+take the opportunity to tell you something of Tom Swift, the lad
+who is to figure in this story.
+
+Many of you have already made his acquaintance, when he has
+been speeding about in his airship or fast electric runabout, and
+to others we will state that our hero first made his bow to the
+public in the book called "Tom Swift and His Motor-Cycle," the
+initial volume of this series.
+
+In that story there was related how Tom made the acquaintance
+of an odd individual, named Mr. Wakefield Damon, who was
+continually blessing himself, some part of his anatomy, or his
+possessions. Mr. Damon was riding a motor-cycle, and it started
+to climb a tree, to his pain and fright. Afterward Tom purchased
+the machine, and had many adventures on it, including a chase
+after a gang of men who had stolen a valuable patent model
+belonging to Mr. Swift.
+
+Mr. Swift, and his son were both inventors. They lived together
+in a fine house in the suburbs of Shopton, New York, and with
+them dwelt Mrs. Baggert, the housekeeper (for Tom's mother was
+dead), and also Garret Jackson, an expert engineer, who aided the
+young inventor and his father in perfecting many machines.
+
+There was also another semi-member of the household, to wit,
+Eradicate Sampson, an eccentric colored man, who owned a mule
+called Boomerang. Eradicate did odd jobs around the place, and
+the mule assisted his owner--that is when the mule felt like it.
+
+In the second volume of the series, entitled "Tom Swift and His
+Motor-Boat," there was related the incidents following a pursuit
+after a gang of unprincipled men, who sought to get Possession of
+some of Mr. Swift's patents, and it was while in this boat that
+Tom, his father, and a friend, Ned Newton, rescued from Lake
+Carlopa a Mr. John Sharp, who fell from his burning balloon. Mr.
+Sharp was a skilled aeronaut, and after his recovery he joined
+Tom in building a big airship, called the Red Cloud. Tom's
+adventures in this craft are set down in detail in the third
+volume of the series, called "Tom Swift and His Airship." Not
+only did he and Mr. Sharp and Mr. Damon make a great trip, but
+they captured some bank robbers, and incidentally cleared
+themselves from the imputation of having looted the vault of
+seventy-five thousand dollars, which charge was fostered by a
+certain Mr. Foger, and his son Andy, who was Tom's enemy.
+
+Not satisfied with having conquered the air, Tom and his father
+set to work to gain a victory over the ocean. They built a boat
+that could navigate under water, and, in the fourth book of the
+series, called "Tom Swift and His Submarine Boat," you will find
+an account of how they went under the ocean to secure a sunken
+treasure, and the fight they had with their enemies who sought to
+get it away from them. They went through many perils, not the
+least of which was capture by a foreign warship.
+
+In the fifth book, entitled "Tom Swift and His Electric
+Runabout," there was told the story of a wonderfully speedy
+electric automobile the young inventor constructed, and how he
+made a great race in it, and saved from ruin a bank, in which his
+father and Mr. Damon were interested.
+
+Tom's ability as an inventor had, by this time, become well
+known. One day, as related in a volume called "Tom Swift and His
+Wireless Message," he received a letter from a Mr. Hosmer
+Fenwick, of Philadelphia, asking his aid in perfecting an airship
+which the resident of the Quaker City had built, but which would
+not work. In his small monoplane, the Butterfly, Tom and Mr.
+Damon went to Philadelphia, as Mr. Damon was acquainted with Mr.
+Fenwick.
+
+Tom carefully inspected the Whizzer which was the name of Mr.
+Fenwick's airship, and, after some difficulties, succeeded in
+getting the electric craft in shape to make a flight.
+
+Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape
+May in the Whizzer, but were caught in a terrific storm, and
+blown out to sea. The wind became a hurricane, the airship was
+disabled, and wrecked in mid-air. When it fell to earth it landed
+on one of the small West Indian islands, but what was the terror
+of the three castaways to find that the island was subject to
+earthquake shocks.
+
+But the earth-tremors were not the only surprise in store for
+Tom and his two friends, On the island they found five men and
+two ladies, who, by strange chance, had been stranded there when
+the yacht Resolute, owned by Mr. George Hosbrook, was wrecked in
+the same storm that disabled the airship. Mr. Hosbrook, a
+millionaire, was taking a party of friends to the West Indies.
+
+When the castaways (among whom were Mr. and Mrs. Amos Nestor,
+parents of Mary Nestor, a girl of whom Tom was very fond) found
+that there was danger of the island being destroyed in an
+earthquake, they were in despair. There seemed no way of being
+rescued, as the island was out of the line of regular ship
+travel.
+
+Tom, however, was resourceful. With the electrical apparatus
+from the wrecked airship, he built a wireless plant, and sent
+messages for help, broadcast over the ocean.
+
+They were finally heard, and answered, by an operator on board
+the steamer Camberanian, which came on under forced draught, and
+rescued Tom and his friends. It was only just in time, for, no
+sooner had they gotten aboard the steamer in lifeboats, than the
+whole island was destroyed by an earthquake shock.
+
+But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick,
+and all the others, got safely home. Among the survivors from the
+yacht Resolute was a Mr. Barcoe Jenks, who now, most unexpectedly,
+had confronted Tom through the glass window of the jewelry
+store. Mr. Jenks was a peculiar man. Tom discovered this on Earthquake
+Island. Mr. Jenks carried with him some stones which he said were
+diamonds. He asserted that he had made them, but Tom did not know
+whether or not to believe this.
+
+When it seemed that the castaways would not be saved Mr. Jenks
+offered Tom a large sum in these same diamonds for some plan
+whereby he might escape the earthquakes. Mr. Jenks said there was
+a certain secret in connection with the manufactured diamonds
+that he had to solve--that he had been defrauded of his rights--and
+that a certain Phantom Mountain figured in it. But Tom, at that time,
+paid little attention to Mr. Jenks' talk. The time was to come,
+however, when he would attach much importance to it.
+
+When this story opens, Tom was more interested in Mr. Barcoe
+Jenks than in any one else, and was wondering what he wanted to
+see him about. The young inventor could not quite understand how
+Mr. Track, the jeweler, could come back with a lad he suspected
+of being a thief, when the person who had acted so suspiciously,
+and who had knocked on the glass, was the queer man, Mr. Jenks.
+
+"Yes, Tom I caught him," the jeweler went on. "I chased after
+him, and nabbed him. It was hard work, too, for I'm not a good
+runner. Now, you little rascal, tell me why you tried to rob my
+store?" and the diamond merchant shook the lad roughly.
+
+"I--I didn't try to rob your store," was the timid answer.
+
+"Well, perhaps you didn't, exactly, but your confederates did.
+Why did you rap on the glass, and why were you staring in so
+intently?"
+
+"I wasn't lookin' in."
+
+"Well, if it wasn't you, it was some one just like you. But why
+did you run when I raced down the street?"
+
+"I--I don't know," and the lad began to snivel. "I--I jest ran--that's
+all--'cause I see everybody else runnin', an' I thought
+there was a fire."
+
+"Ha! That's a likely story! You ran because you are guilty! I'm
+going to hand you over to the police."
+
+"Did he get anything, Mr. Track?" asked one of the men who had
+joined the jeweler in the chase.
+
+"No, I can't say that he did. He didn't get a chance. Tom Swift
+was in here at the time. But this fellow was only waiting for a
+chance to steal, or else to aid his confederates."
+
+"But, if he didn't take anything, I don't see how you can have
+him arrested," went on the man.
+
+"On suspicion; that's how!" asserted Mr. Track. "Will some one
+get me a constable?"
+
+"I wouldn't call a constable," said Tom, quietly.
+
+"Why not?"
+
+"Because that isn't the person who looked in your window."
+
+"How do you know, Tom?"
+
+"Because that person came back while you were out. I saw him."
+
+"You saw him? Did he try to steal any of my diamonds, Tom?"
+
+"No, I guess he doesn't need any."
+
+"Why not?" There was wonder in the jeweler's tone.
+
+"Why, he claims he can make all he wants."
+
+"Make diamonds?"
+
+"So he says."
+
+"Why, he must be crazy!" and Mr. Track laughed.
+
+"Perhaps he is," admitted Tom, "I'm only telling you what he
+says. He's the person who acted so suspiciously. He came back
+here, I'm telling you, while you were running down the street,
+and spoke to me."
+
+"Oh, then you know him?" The jeweler's voice was suspicious.
+
+"I didn't at first," admitted Tom. "But when he said he was Mr.
+Barcoe Jenks, I remembered that I had met him when I was cast
+away on Earthquake Island."
+
+"And he says he can make diamonds?" asked Mr. Track.
+
+"What did he want of you?" and the jeweler looked at Tom,
+quizzically.
+
+"He wanted to have a talk with me," replied the lad, "and when
+he saw me in your store, he tried to attract my attention by
+knocking on the glass."
+
+"That's a queer way to do," declared Mr. Track. "What did he
+want?"
+
+"I don't know exactly," answered Tom, not caring to go into
+details just then. "But I'm sure, Mr. Track, that you've got the
+wrong person there. That lad never looked in the window, nor
+knocked on the glass."
+
+"That's right--I didn't," asserted the captive.
+
+The jeweler looked doubtful.
+
+"Why did you run?" he asked.
+
+"I told you, I thought there was a fire."
+
+"That's right, I don't believe he's the fellow you want," put
+in another man. "I was standing on the corner, near White's
+grocery store, and I noticed this lad. That was before I heard
+you yelling, and saw you coming, and then I joined in the chase.
+I guess the man you were after got away, Track."
+
+"He did," asserted Tom. "He came back here, a little while ago,
+and he ran away just now, as he heard you coming."
+
+"Where did he go?" asked the jeweler, eagerly.
+
+"I don't know," answered Tom. "Only you've got the wrong lad
+here."
+
+"Well, perhaps I have," admitted the diamond merchant. "You can
+go, youngster, but next time, don't run if you're not guilty."
+
+"I thought there was a fire," repeated the lad, as he hurriedly
+slipped through the crowd in the store, and disappeared down the
+dark street.
+
+"Well, I guess the excitement's all over, and, anyhow, you
+weren't robbed, Track," said a stout man, as he left the store.
+The others soon followed, and Tom and the jeweler were once more
+alone in the shop.
+
+"Can you tell me something about this man, Tom?" asked Mr.
+Track, eagerly. "So he really makes diamonds. Who is he?"
+
+"I'd rather not tell--just now," replied the young inventor. "I
+don't take much stock in him, myself. I think he's visionary. He
+may think he has made diamonds, and he may have made some stones
+that look like them. I'm very skeptical."
+
+"If you could bring me some, Tom, I could soon tell whether
+they were real or not. Can you?"
+
+The lad shook his head.
+
+"I don't expect to see Mr. Jenks again," he said. "He talked
+rather wildly about waiting to meet me, but that man is odd--crazy,
+perhaps--and I don't imagine I'll see him. He's harmless,but he's
+eccentric. Well, there was quite some excitement for a time."
+
+"I should say there was. I thought it was a plan to rob me,"
+and the jeweler began putting away the diamond pins. In fact, the
+excitement so filled the minds of himself and Tom that neither of
+them thought any more of the object of the lad's visit, and the
+young inventor departed without purchasing the pin he had come after.
+
+It was not until he was out on the street, walking toward his
+home, that the matter came back to his mind.
+
+"I declare!" he exclaimed. "I didn't get that pin for Mary,
+after all! Well, never mind, I have a week until her birthday,
+and I can get it to-morrow."
+
+He walked rapidly toward home, for the weather looked
+threatening, and Tom had no umbrella. He was musing on the
+happenings of the evening when he reached his house. His father
+was out, as was Garret Jackson, the engineer; and Mrs. Baggert,
+the housekeeper, was entertaining a lady in the sitting-room, so,
+as Tom was rather tired, he went directly to his own room, and, a
+little later got into bed.
+
+It was shortly after midnight when he was awakened by hearing a
+rattling on the window of his room. The reason he was able to fix
+the time so accurately was because as soon as he awakened he
+pressed a little electric button, and it illuminated the face of
+a small clock on his bureau. The hands pointed to five minutes
+past twelve.
+
+"Humph! That sounds like hail!" exclaimed Tom, as he arose, and
+looked out of the casement. "I wonder if any of the skylights of
+the airship shed are open? There might be some damage. Guess I'd
+better go out and take a look."
+
+He had mentally reasoned this far before he had looked out, and
+when he saw that the moon was brightly shining in a clear sky, he
+was a bit surprised.
+
+"Why--that wasn't hail," he murmured. "It isn't even raining. I
+wonder what it was?"
+
+He was answered a moment later, for a shower of fine gravel
+from the walk flew up and clattered against the glass. With a
+start, Tom looked down, and saw a dark figure standing under an
+apple tree.
+
+"Hello! Who's there?" called the lad, after he had raised the
+sash.
+
+"It's I--Mr. Jenks," was the surprising answer.
+
+"Mr. Jenks?" repeated Tom.
+
+"Yes--Barcoe Jenks, of Earthquake Island."
+
+"You here? What do you want?"
+
+"Can you come down?"
+
+"What for?"
+
+"Tom Swift, I've something very important to tell you," was the
+answer in a low voice, yet which carried to Tom's ears perfectly.
+"Do you want to make a fortune for yourself--and for me?"
+
+"How?" Tom was beginning to think more and more that Mr. Jenks
+was crazy.
+
+"How? By helping me to discover the secret of Phantom Mountain,
+where the diamonds are made! Will you?"
+
+"Wait a minute--I'll come down," answered Tom, and he began to
+grope for his clothes in the dim light of the little electric
+lamp.
+
+What was the secret of Phantom Mountain? What did Mr. Jenks
+really want? Could he make diamonds? Tom asked himself these
+questions as he hastily dressed to go down to his midnight
+visitor.
+
+
+
+
+CHAPTER III--A STRANGE STORY
+
+
+"Well, Mr. Jenks," began Tom, when he had descended to the
+garden, and greeted the man who had acted so strangely on
+Earthquake Island, "this is rather an odd time for a visit."
+
+"I realize that, Tom Swift," was the answer, and the lad
+noticed that the man spoke much more calmly than he had that
+evening at the jewelry shop. "I realize that, but I have to be
+cautious in my movements."
+
+"Why?"
+
+"Because there are enemies on my track. If they thought I was
+seeking aid to discover the secret of Phantom Mountain, my life
+might pay the forfeit."
+
+"Are you in earnest, Mr. Jenks?"
+
+"I certainly am, and, while I must apologize for awakening you
+at this unseemly hour, and for the mysterious nature of my visit,
+if you will let me tell my story, you will see the need of
+secrecy."
+
+"Oh, I don't mind being awakened," answered Tom, good-naturedly,
+"but I will be frank with you, Mr. Jenks. I hardly can believe what
+you have stated to me several times--that you know how diamonds
+can be made."
+
+"I can prove it to you," was the quiet answer.
+
+"Yes, I know. For centuries men have tried to discover the
+secret of transmuting base metals into gold, and how to make
+diamonds by chemical means. But they have all been failures."
+
+"All except this process--the process used at Phantom
+Mountain," insisted the queer man. "Do you want to hear my
+story?"
+
+"I have no objections."
+
+"Then let me warn you," went on Mr. Jenks, "that if you do hear
+it, you will be so fascinated by it that I am sure you will want
+to cast your lot in with mine, and aid me to get my rights, and
+solve the mystery. And I also want to warn you that if you do,
+there is a certain amount of danger connected with it."
+
+"I'm used to danger," answered Tom, quietly. "Let me hear your
+story. But first explain how you came to come here, and why you
+acted so strangely at the jewelry store."
+
+"Willingly. I tried to attract your attention at the store,
+because I saw that you were going to buy a diamond, and I didn't
+want you to."
+
+"Why not?"
+
+"Because I want to present you with a beautiful stone, that
+will answer your purpose as well or better, than any one you
+could buy. That will prove my story better than any amount of
+words or argument. But I could not attract your attention without
+also attracting that of the jeweler. He became suspicious, gave
+chase, and I thought it best to vanish. I hope no one was made to
+suffer for what may have been my imprudence."
+
+"No, the lad whom Mr. Track caught was let go. But how did you
+happen to come to Shopton?"
+
+"To see you. I got your address from the owner of the yacht
+Resolute. I knew that if there was one person who could aid me to
+recover my rights, it would be you, Tom Swift. Will you help me?
+Will you come with me to discover the secret of Phantom Mountain?
+If we go, it will have to be in an airship, for in no other way,
+I think, can we come upon the place, as it is closely guarded.
+Will you come? I will pay you well."
+
+"Perhaps I had better hear your story," said the young
+inventor. "But first let me suggest that we move farther away
+from the house. My father, or Mr. Jackson, or the housekeeper,
+may hear us talking, and it may disturb them. Come with me to my
+private shop," and Tom led the way to a small building where he
+did experimental work. He unlocked the door with a key he
+carried, turned on the lights, which were run by a storage
+battery, and motioned Mr. Jenks to a seat.
+
+"Now I'll hear your story," said Tom.
+
+"I'll make it as short as possible," went on the queer man. "To
+begin with, it is now several years ago since a poorly dressed
+stranger applied to me one night for money enough to get a meal
+and a bed to sleep in. I was living in New York City at the time,
+and this was midnight, as I was returning home from my club.
+
+"I was touched by the man's appearance, and gave him some
+money. He asked for my card, saying he would repay me some day. I
+gave it to him, little thinking I would hear from the man again.
+But I did. He called at my apartments about a week later, saying
+he had secured work as an expert setter of diamonds, and wanted
+to repay me. I did not want to take his money, but the fact that
+such a sorry looking specimen of manhood as he had been when I
+aided him, was an expert handler of gems interested me. I talked
+with the man, and he made a curious statement.
+
+"This man, who gave his name as Enos Folwell, said he knew a place
+where diamonds could be made, partly in a scientific manner, and
+partly by the forces of nature. I laughed at him, but he told me so
+many details that I began to believe him. He said he and some other
+friends of his, who were diamond cutters, had a plant in the midst of
+the Rocky Mountains, where they had succeeded in making several small,
+but very perfect diamonds. They had come to the end of their rope,
+though, so to speak, because they could not afford to buy the materials
+needed. Folwell said that he and his companions had temporarily
+separated, had left the mountain where they made diamonds, and agreed
+to meet there later when they had more money with which to purchase
+materials. They had all agreed to go out into civilization, and work
+for enough funds to enable them to go on with their diamond making.
+
+"I hardly knew whether to believe the man or not, but he
+offered proof. He had several small, but very perfect diamonds
+with him, and he gave them to me, to have tested in any way I
+desired.
+
+"I promised to look into the matter, and, as I was quite
+wealthy, as, in fact I am now, and if I found that the stones he
+gave me were real, I said I might invest some money in the
+plant."
+
+"Were the diamonds good?" asked Tom, who was beginning to be
+interested.
+
+"They were--stones of the first water, though small. An expert
+gem merchant, to whom I took them, said he had never seen any
+diamonds like them, and he wanted to know where I got them. Of
+course I did not tell him.
+
+"To make a long story short, I saw Folwell again, told him to
+communicate with his companions, and to tell them that I would
+agree to supply the cash needed, if I could share in the diamond
+making. To this they agreed, and, after some weeks spent in
+preparation, a party of us set out for Phantom Mountain."
+
+"Phantom Mountain?" interrupted Tom. "Where is it?"
+
+"I don't know, exactly--it's somewhere in the Rockies, but the
+exact location is a mystery. That is why I need your help. You
+will soon understand the reason. Well, as I said, myself, Folwell
+and the others, who were not exactly prepossessing sort of men,
+started west. When we got to a small town, called Indian Ridge,
+near Leadville, Colorado, the men insisted that I must now
+proceed in secret, and consent to be blindfolded, as they were
+not yet ready to reveal the secret of the place where they made
+the diamonds.
+
+"I did not want to agree to this, but they insisted, and I gave
+in, foolishly perhaps. At any rate I was blindfolded one night,
+placed in a wagon, and we drove off into the mountains. After
+traveling for some distance I was led, still blindfolded, up a
+steep trail.
+
+"When the bandage was taken off my eyes I saw that I was in a
+large cave. The men were with me, and they apologized for the
+necessity that caused them to blindfold me. They said they were
+ready to proceed with the making of diamonds, but I must promise
+not to seek to discover the secret until they gave me permission,
+nor was I to attempt to leave the cave. I had to agree.
+
+"Next they demanded that I give them a large sum, which I had
+promised when they showed me, conclusively, that they could make
+diamonds. I refused to do this until I had seen some of the
+precious stones, and they agreed that this was fair, but said I
+would have to wait a few days.
+
+"Well, I waited, and, all that while, I was virtually a
+prisoner in the cave. All I could learn was that it was in the
+midst of a great range, near the top, and that one of the peaks
+was called Phantom Mountain. Why, I did not learn until later.
+
+"At last one night, during a terrific thunder storm, the
+leader of the diamond makers--Folwell--announced that I could now
+see the stones made. The men had been preparing their chemicals
+for some days previous. I was taken into a small chamber of the
+cave, and there saw quite a complicated apparatus. Part of it was
+a great steel box, with a lever on it.
+
+"We will let you make some diamonds for yourself," Folwell said
+to me, and he directed me to pull the lever of the box, at a
+certain signal. The signal came, just as a terrific crash of
+thunder shook the very mountain inside of which we were. The box
+of steel got red-hot, and when it cooled off it was opened, and
+was given a handful of white stones."
+
+"Were they diamonds?" asked Tom, eagerly.
+
+Mr. Jenks held out one hand. In the palm glittered a large
+stone--ostensibly a diamond. In the rays of the moon it showed
+all the colors of the rainbow--a beautiful gem. "That is one of
+the stones I made--or rather that I supposed I had made," went on
+Mr. Jenks. "It is one of several I have, but they have not all
+been cut and polished as has this one.
+
+"Naturally I was much impressed by what I saw, and, after I had
+made certain tests which convinced me that the stones in the
+steel box were diamonds, I paid over the money as I had promised.
+That was my undoing."
+
+"How?"
+
+"As soon as the men got the cash, they had no further use for
+me. The next I remember is eating a rude meal, while we discussed
+the future of making diamonds. I knew nothing more until I found
+myself back in the small hotel at Indian Ridge, whence I had gone
+some time previous, with the men, to the cave in the mountain."
+
+"What happened?" asked Tom, much surprised by the unexpected
+outcome of the affair. "I had been tricked, that was all! As soon
+as the men had my money they had no further use for me. They did
+not want me to learn the secret of their diamond making, and they
+drugged me, carried me away from the cave, and left me in the
+hotel."
+
+"Didn't you try to find the cave again?"
+
+"I did, but without avail. I spent some time in the Rockies,
+but no one could tell where Phantom Mountain was; in fact, few
+had heard of it, and I was nearly lost searching for it.
+
+"I came back East, determined to get even. I had given the men
+a very large sum of money, and, in exchange, they had given me
+several diamonds. Probably the stones are worth nearly as much as
+the money I invested, but I was cheated, for I was promised an
+equal share in the profits. These were denied me, and I was
+tricked. I determined to be revenged, or at least to discover the
+secret of making diamonds. It is my right."
+
+"I agree with you," spoke Tom.
+
+"But, up to the time I met you on Earthquake Island, I could
+form no plan for discovering Phantom Mountain, and learning the
+secret of the diamond makers," went on Mr. Jenks. "I carried the
+gems about with me, as you doubtless saw when we were on the
+island. But I knew I needed an airship in which to fly over the
+mountains, and pick out the location of the cave where the
+diamonds are made."
+
+"But how can you locate it, if you were blindfolded when you
+were taken there, Mr. Jenks?"
+
+"I forgot to tell you that, on our journey into the mountains,
+and just before I was carried into the cave, I managed to raise
+one corner of the bandage. I caught a glimpse of a very
+peculiarly shaped cliff--it is like a great head, standing out in
+bold relief against the moonlight, when I saw it. That head of
+rock is near the cave. It may be the landmark by which we can
+locate Phantom Mountain."
+
+"Perhaps," admitted the young inventor.
+
+"What I want to know is this," went on Mr. Jenks. "Will you go
+with me on this quest--go in your airship to discover the secret
+of the diamond makers? If you will, I will share with you
+whatever diamonds we can discover, or make; besides paying all
+expenses. Will you go, Tom Swift?"
+
+The young inventor did not know what to answer. How far was Mr.
+Jenks to be trusted? Were the stones he had real diamonds? Was
+his story, fantastical as it sounded--true? Would it be safe for
+Tom to go?
+
+The lad asked himself these questions. Mr. Jenks saw his
+hesitation.
+
+"Here," said the strange man, "I will prove what I say. Take
+this diamond. I intended it for you, anyhow, for what you did for
+me on Earthquake Island. Take it, and--and give it to the person
+for whom you were about to purchase a diamond to-night. But,
+first of all, take it to a gem expert, and get his opinion. That
+will prove the truth of what I say, Tom Swift, and I feel sure
+that you will cast your lot in with mine, and help me to discover
+the secret of Phantom Mountain, and aid me to get my rights from
+the diamond makers!"
+
+
+
+
+CHAPTER IV--ANDY FOGER GETS A FRIGHT
+
+
+Tom Swift considered a few minutes. On the face of it, the
+proposition appealed to him. He had been home some time now after
+his adventures on Earthquake Island, and he was beginning to long
+for more excitement. The search for the mysterious mountain, and
+the cave of the diamond makers, might offer a new field for him.
+But there came to him a certain distrust of Mr. Jenks.
+
+"I don't like to doubt your word," began Tom, slowly, "but you
+know, Mr. Jenks, that some of the greatest chemists have tried in
+vain to make diamonds; or, at best, they have made only tiny
+ones. To think that any man, or set of men, made real diamonds as
+large as the ones you have, doesn't seem--well--" and Tom
+hesitated.
+
+"You mean you can hardly believe me?" asked Mr. Jenks.
+
+"I guess that's it," assented Tom.
+
+"I don't blame you a bit!" exclaimed the odd man. "In fact, I
+didn't believe it when they told me they could make diamonds. But
+they proved it to me. I'm ready now to prove it to you."
+
+"I'll tell you what I'll do. Here's this one stone, cut ready
+for setting. Here's another, uncut," and Mr. Jenks drew from his
+pocket what looked like a piece of crystal. "Take them to any
+jeweler," he resumed--"to the one in whose place I saw you to-night.
+I'll abide by the verdict you get, and I'll come here to-morrow
+night, and hear what you have to say."
+
+"Why do you come at night?" asked Tom, thinking there was
+something suspicious in that.
+
+"Because my life might be in danger if I was seen talking to
+you, and showing you diamonds in the daytime--especially just
+now.
+
+"Why at this particular time?"
+
+"For the reason that the diamond makers are on my trail. As
+long as I remained quiet, after their shabby treatment of me, and
+did not try to discover their secret, they were all right. But,
+after I realized that I had been cheated out of my rights, and
+when I began to make an investigation, with a view to discovering
+their secret whereabouts, I received mysterious and anonymous
+warnings to stop."
+
+"But I did not. I came East, and tried to get help to discover
+the cave of the diamond makers, but I was unsuccessful. I needed
+an airship, as I--said, and no person who could operate one,
+would agree to go with me on the quest. Again I received a
+warning to drop all search for the diamond makers, but I
+persisted, and about a week ago I found I was being shadowed."
+
+"Shadowed; by whom?" asked Tom.
+
+"By a man I never remember seeing, but who, I have no doubt, is
+one of the diamond-making gang."
+
+"Do you think he means you harm?"
+
+"I'm sure of it. That is the reason I have to act so in secret,
+and come to see you at night. I don't want those scoundrels to
+find out what I am about to do. On my return from Earthquake
+Island, I again endeavored to interest an airship man in my plan,
+but he evidently thought me insane. Then I thought of you, as I
+had done before, but I was afraid you, too, would laugh at my
+proposition. However, I decided to come here, and I did. It
+seemed almost providential that my first view of you was in a
+jewelry shop, looking at diamonds. I took it as a good omen. Now
+it remains with you. May I call here to-morrow night, and get
+your answer?"
+
+Tom Swift made up his mind quickly. After all it would be easy
+enough to find out if the diamonds were real. If they were, he
+could then decide whether or not to go with Mr. Jenks on the
+mysterious quest. So he answered:
+
+"I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow
+night. In the meanwhile, for my own satisfaction, I'll let
+an expert look at these stones."
+
+"Get the greatest diamond expert in the world, and he'll
+pronounce them perfect!" predicted the odd man. "Now I'll bid you
+goodnight, and be going. I'll be here at this time to-morrow."
+
+As Mr. Jenks turned aside there was a movement among the trees
+in the orchard, and a shadowy figure was seen hurrying away.
+
+"Who's that?" asked the diamond man, in a hoarse whisper. "Did
+you see that, Tom Swift? Some one was here--listening to what I
+said! Perhaps it was the man who has been shadowing me!"
+
+"I think not. I guess it was Eradicate Sampson, a colored man
+who does work for us," said Tom. "Is that you, Rad?" he called.
+
+"Yais, sah, Massa Tom, heah I is!" answered the voice of the
+negro, but it came from an entirely different direction than that
+in which the shadowy figure had been seen.
+
+"Where are you, Rad?" called the young inventor.
+
+"Right heah," was the reply, and the colored man came from the
+direction of the stable. "I were jest out seein' if mah mule
+Boomerang were all right. Sometimes he's restless, an' don't
+sleep laik he oughter."
+
+"Then that wasn't you over in the orchard?" asked Tom, in some
+uneasiness.
+
+"No, sah, I ain't been in de orchard. I were sleepin' in mah
+shack, till jest a few minutes ago, when I got up, an' went in t'
+see Boomerang. I had a dream dat some coon were tryin t' steal
+him, an' it sort ob 'sturbed me, laik."
+
+"If it wasn't your man, it was some one else," said Mr. Jenks,
+decidedly.
+
+"We'll have a look!" exclaimed Tom. "Here, Rad, come over and
+scurry among those trees. We just saw some one sneaking around."
+
+"I'll sure do dat!" cried the colored man. "Mebby it were
+somebody arter Boomerang! I'll find 'em."
+
+"I don't believe it was any one after the mule," murmured Mr.
+Jenks, "but it certainly was some one--more likely some one after
+me."
+
+The three made a hasty search among the trees, but the intruder
+had vanished, leaving no trace. They went out into the road,
+which the moon threw into bold relief along its white stretch,
+but there was no figure scurrying away.
+
+"Whoever it was, is gone," spoke Tom. "You can go back to bed,
+Rad," for the colored man, of late, had been sleeping in a shack
+on the Swift premises.
+
+"And I guess it's time for me to go, too," added Mr. Jenks.
+"I'll be here to-morrow night, Tom, and I hope your answer will
+be favorable."
+
+Tom did not sleep well the remainder of the night, for his
+fitful slumbers were disturbed by dreams of enormous caves,
+filled with diamonds, with dark, shadowy figures trying to put
+him into a red-hot steel box. Once he awakened with a start, and
+put his hand under his pillow to feel if the two stones Mr. Jenks
+had given him, were still there. They had not been disturbed.
+
+Tom made up his mind to find out if the stones were really
+diamonds, before saying anything to his father about the chance
+of going to seek Phantom Mountain. And the young inventor wished
+to get the opinion of some other jeweler than Mr. Track--at
+least, at first.
+
+"Though if this one proves to be a good gem, I'll have Mr.
+Track set it in a brooch, and give it to Mary for her birthday,"
+decided the young inventor. "Guess I'll take a run over to
+Chester in the Butterfly, and see what one of the jewelers there
+has to say."
+
+In addition to his big airship, Red Cloud, Tom owned a small,
+swift monoplane, which he called Butterfly. This had been damaged
+by Andy Foger just before Tom left on the trip that ended at
+Earthquake Island, but the monoplane had been repaired, and Andy
+had left town, not having returned since.
+
+Telling his father that he was going off on a little business
+trip, which he often did in his aeroplane, Tom, with the aid of
+Mr. Jackson, the engineer, wheeled the Butterfly out of its shed.
+
+Adjusting the mechanism, and seeing that it was in good shape,
+Tom took his place in one of the two seats, for the monoplane
+would carry two. Mr. Jackson then spun the propellers, and, with
+a crackle and roar the motor started. Over the ground ran the
+dainty, little aeroplane, until, having momentum enough, Tom
+tilted the wing planes and the machine sailed up into the air.
+
+Rising about a thousand feet, and circling about several times
+to test the wind currents, Tom headed his craft toward Chester,
+a city about fifty miles from Shopton. In his pocket, snugly
+tucked away, were the two stones Mr. Jenks had given him.
+
+It was not long before Tom saw, looming up in the distance the
+church spires and towering factory chimneys of Chester, for his
+machine was a speedy one, and could make ninety miles an hour
+when driven. But now a slower speed satisfied our hero.
+
+"I'll just drop down outside of the city," he reasoned, "for
+too much of a crowd gathers when I land in the street. Besides I
+might frighten horses, and then, too, it's hard to get a good
+start from the street. I'll leave it in some barn until I want to
+go back."
+
+Tom sent his craft down, in order to pick out a safe place for
+a landing. He was then over the suburbs of the city, and was
+following the line of a straight country road.
+
+"Looks like a good place there," he murmured. "I'll shut off
+the motor, and vol-plane down."
+
+Suiting the action to the word, Tom shut off his power. The
+little craft dipped toward the ground, but the lad threw up the
+forward planes, and caught a current of air that sent him
+skimming along horizontally.
+
+As he got nearer to the ground, he saw the figure of a lad
+riding a bicycle along the country highway. Something about the
+figure struck Tom as being familiar, and he recognized the
+cyclist a moment later.
+
+"It's Andy Foger!" said Tom, in a whisper. "I wondered where he
+had been keeping himself since he damaged the Butterfly.
+Evidently he doesn't dare venture back to Shopton. Well, here's
+where I give him a scare."
+
+Tom's monoplane was making no more noise, now, than a soaring
+bird. He was gliding swiftly toward the earth, and, with the plan
+in his mind of administering some sort of punishment to the
+bully, he aimed the machine directly at him.
+
+Nearer and nearer shot the monoplane, as quietly as a sheet of
+paper might fall. Andy pedaled on, never looking up nor behind
+him, A moment later, as Tom threw up his headplanes, to make his
+landing more easy, and just as he swooped down at one side of the
+cyclist, our hero let out a most alarming yell, right into Andy's
+ear.
+
+"Now I've got you!" he shouted. "I'll teach you to slash my
+aeroplane! Come with me!"
+
+Andy gave one look at the white bird-like apparatus that had
+flown up beside him so noiselessly, and, being too frightened to
+recognize Tom's voice, must have thought that he had been
+overtaken by some supernatural visitor.
+
+Andy gave a yell like an Indian, about to do a stage scalping
+act, and fairly dived over the handlebars of his bicycle,
+sprawling in a heap on the dusty road.
+
+"I guess that will hold you for a while," observed Tom, grimly,
+as he put on the ground-brake and brought his monoplane to a stop
+not far from the fallen rider.
+
+
+
+
+CHAPTER V--A MYSTERIOUS MAN
+
+
+For several minutes Andy Foger did not arise. He remained
+prostrate in the dust, and Tom, observing him, thought perhaps
+the bully might have been seriously injured. But, a little later,
+Andy cautiously raised his head, and inquired in a frightened
+voice:
+
+"Is it--is it gone?"
+
+"Is what gone?" asked Tom, grimly.
+
+At the sound of his voice, Andy looked up. "Was that you, Tom
+Swift?" he demanded. "Did you knock me off my wheel?"
+
+"My monoplane and I together did," was the reply; "or, rather,
+we didn't. It was the nervous reaction caused by your fright, and
+the knowledge that you had done wrong, that made you jump over
+the handlebars. That's the scientific explanation."
+
+"You--you did it!" stammered Andy, getting to his feet. He
+wasn't hurt much, Tom thought.
+
+"Have it your own way," resumed our hero. "Did you think it was
+a hob-goblin in a chariot of fire after you, Andy?"
+
+"Huh! Never mind what I thought! I'll have you arrested for
+this!"
+
+"Will you? Delighted, as the boys say. Hop in my airship and
+I'll take you right into town. And when I get you there I'll make
+a charge of malicious mischief against you, for breaking the
+propeller of the Butterfly and slashing her wings. I've mended
+her up, however, so she goes better than ever, and I can take you
+to the police station in jig time. Want to come, Andy?"
+
+This was too much for the bully. He knew that Tom would have a
+clear case against him, and he did not dare answer. Instead he
+shuffled over to where his wheel lay, picked it up, and rode
+slowly off.
+
+"Good riddance," murmured Tom. He looked about, and saw that he
+was near a house, in the rear of which was a good-sized barn.
+"Guess I'll ask if I can leave the Butterfly there," he murmured,
+and, ringing the doorbell, he was greeted by a man.
+
+"I'll pay you if you'll let me store my machine in the barn a
+little while, until I go into the city, and return," spoke the
+lad.
+
+"Indeed, you're welcome to leave it there without pay," was the
+answer. "I'm interested in airships, and, I'll consider it a
+favor if you'll let me look yours over while it's here."
+
+Tom readily agreed, and a few minutes later he had caught a
+trolley going into the city. He was soon in one of the largest
+jewelry stores of Chester.
+
+"I'd like to get an expert opinion as to whether or not those
+stones are diamonds," spoke Tom, to the polite clerk who came up
+to wait on him, and our hero handed over the two gems which Mr.
+Jenks had given him. "I'm willing to pay for the appraisement, of
+course," the young inventor added, as he saw the clerk looking
+rather doubtfully at him, for Tom had on a rough suit, which he
+always donned when he flew in his monoplane.
+
+"I'll turn them over to our Mr. Porter, a gem expert," said the
+clerk. "Please be seated."
+
+The young man disappeared into a private office with the
+stones, and Tom waited. He wondered if he was going to have his
+trouble for his pains. Presently two elderly gentlemen came from
+the little room, on the glass door of which appeared the word
+"Diamonds."
+
+"Who brought these stones in?" asked one of the men, evidently
+the proprietor, from the deference paid him by the clerk. The
+latter motioned to Tom.
+
+"Will you kindly step inside here?" requested the elderly man.
+When the door was closed, Tom found himself in a room which was
+mostly taken up with a bench for the display of precious stones,
+a few chairs, and some lights arranged peculiarly; while various
+scales and instruments stood on a table.
+
+"You wished an opinion on--on these?" queried the proprietor of
+the place. Tom noticed at once that the word "diamonds" was not
+used.
+
+"I wanted to find out if they were of any value," he said. "Are
+they diamonds?"
+
+"Would you mind stating where you got them?" asked the other of
+the two men.
+
+"Is that necessary?" inquired the lad. "I came by them in a
+legitimate manner, if that's what you mean, and I can satisfy you
+on that point. I am willing to pay for any information you may
+give me as to their value."
+
+"Oh, it isn't that," the proprietor hastened to assure him.
+"But these are diamonds of such a peculiar kind, so perfect and
+without a flaw, that I wondered from what part of the world they
+came."
+
+"Then they are diamonds?" asked Tom, eagerly.
+
+"The finest I have ever tested!" declared the other man,
+evidently Mr. Porter, the gem expert. "They are a joy to look at,
+Mr. Roberts," he went on, turning to the proprietor. "If it is
+possible to get a supply of them you would be justified in asking
+half as much again as we charge for African or Indian diamonds.
+The Kimberly products are not to be compared to these," and he
+looked at the two stones in his hand--the one cut, and sparkling
+brilliantly, the other in a rough state.
+
+"Do you care to state where these diamonds came from?" asked
+Mr. Roberts, looking critically at Tom.
+
+"I had rather not," answered the lad. "It is enough for me to
+know that they are diamonds. How much is your charge?"
+
+"Nothing," was the unexpected answer. "We are very glad to have
+had the opportunity of seeing such stones. Is there any chance of
+getting any more?"
+
+"Perhaps," answered Tom, as he accepted the gems which the
+expert held out to him.
+
+"Then might we speak for a supply?" went on Mr. Roberts,
+eagerly. "We will pay you the full market price."
+
+"What is the value of these stones?" asked Tom.
+
+Mr. Roberts looked at his gem expert.
+
+"It is difficult to say," was the answer of the man who had
+handed Tom the gems. "They are so far superior to the usual run
+of diamonds, that I feel justified in saying that the cut one
+would bring fifteen hundred dollars, anywhere. In fact, I would
+offer that for it. The other is larger, though what it would lose
+in cutting would be hard to say. I should say it was worth two
+thousand dollars as it is now."
+
+"Thirty-five hundred dollars for these two stones!" exclaimed
+Tom.
+
+"They are worth every cent of it," declared Mr. Roberts. "Do
+you want to sell?"
+
+Tom shook his head. He could scarcely believe the good news.
+Mr. Jenks had told the truth. Now the young inventor could go
+with him to seek the diamond makers.
+
+"Can you get any more of these?" went on Mr. Roberts.
+
+"I think so--that is I don't know--I am going to try," answered
+the lad.
+
+"Then if you succeed I wish you would sell us some," fairly
+begged the proprietor of the store.
+
+"I will," promised Tom, but he little knew what lay before him,
+or perhaps he would not have made that promise. He thanked the
+diamond merchant for his kindness, and arranged to have the cut
+stone set in a pin for Miss Nestor. The uncut gem Tom took away
+with him.
+
+Thinking of many things, and wondering how best to start in his
+airship Red Cloud for the mysterious Phantom Mountain, Tom
+hurried back to where he had left the monoplane, wheeled it out,
+and was soon soaring through the air toward Shopton.
+
+"I think I'll go with Mr. Jenks," he decided, as he prepared
+for a landing in the open space near his aeroplane shed. "It will
+be a risky trip, perhaps, but I've taken risks before. When Mr.
+Jenks comes to-night I'll tell him I'll help him to get his
+rights, and discover the secret of the diamond makers."
+
+As Tom was wheeling the Butterfly into the shed, Eradicate came
+out to help him.
+
+"Dere's a gen'man here to see yo', Massa Tom," said the colored
+man.
+
+"Who is it?"
+
+"I dunno. He keep askin' ef yo' de lad what done bust up
+Earthquake Island, an' send lightnin' flashes up to de sky, an'
+all sech questions laik dat."
+
+"It isn't Mr. Damon; is it, Rad? He hasn't been around in some
+time."
+
+"No, Massa Tom, it ain't him. I knows dat blessin' man good an'
+proper. I jest wish he'd bless mah mule Boomerang some day, an'
+take some oh de temper out ob him. No, sah, it ain't Massa Damon.
+De gen'man's in de airship shed waitin' fo' you."
+
+"In the airship shed! No strangers are allowed in there, Rad."
+
+"I knows it, Massa Tom, but he done persisted his se'f inter
+it, an' he wouldn't come out when I told him; an' your pa an' Mr.
+Jackson ain't home."
+
+"I'll see about this," exclaimed Tom, striding to the large
+shed, where the Red Cloud was kept. As he entered it he saw a man
+looking over the wonderful craft.
+
+"Did you want to see me?" asked Tom, sharply, for he did not
+like strangers prowling around.
+
+"I did, and I apologize for entering here, but I am interested
+in airships, and I thought you might want to hire a pilot. I am
+in need of employment, and I have had considerable to do with
+balloons and aeroplanes, but never with an airship like this,
+which combines the two features. Do you wish to hire any one."
+
+"No, I don't!" replied Tom, sharply, for he did not like the
+looks of the man.
+
+"I was told that you did," was the rather surprising answer.
+
+"Who told you?"
+
+The man looked all around the shed, before replying, as if
+fearful of being overheard. Then, stepping close to Tom, he
+whispered:
+
+"Mr. Jenks told me!"
+
+"Mr. Jenks?" Tom could not conceal his astonishment.
+
+"Yes. Mr. Barcoe Jenks. But I did not come here to merely ask
+you for employment. I would like to hire out to you, but the real
+object of my visit was to say this to you."
+
+The man approached still closer to Tom, and, in a lower voice,
+and one that could scarcely be heard, he fairly hissed:
+
+"Don't go with Barcoe Jenks to seek the diamond makers!"
+
+Then, before Tom could put out a hand to detain him, had the
+lad so wished, the man turned suddenly, and fairly ran from the
+shed.
+
+
+
+
+CHAPTER VI-MR. DAMON IS ON HAND
+
+
+The young inventor stood almost spellbound for a few moments.
+Then recovering himself he made a dash for the door through which
+the mysterious man had disappeared. Tom saw him sprinting down
+the road, and was half-minded to take after him, but a cooler
+thought warned him that he had better not.
+
+"He may be one of those men who are on Mr. Jenks' trail,"
+reasoned Tom, in which case it might not be altogether safe to
+attempt to stop him, and make him explain. Or he may be a
+lunatic, and in that case it wouldn't be altogether healthy to
+interfere with him.
+
+"I'll just let him go, and tell Mr. Jenks about him when he
+comes to-night. But I must warn Rad never to let him in here
+again. He might damage the airship."
+
+Calling to the colored man, Tom pointed to the stranger, who
+was almost out of sight down the road, and said earnestly:
+
+"Rad, do you see that fellow?"
+
+"I sho do, Massa Tom, but I sorter has t' strain my eyes t' do
+it. He's goin' laik my mule Boomerang does when he's comm' home
+t' dinnah."
+
+"That's right, Rad. Well, never let that man set foot inside
+our fence again! If he comes, and I'm home, call me. If I'm away,
+call dad or Mr. Jackson, and if you're here alone, drive him
+away, somehow."
+
+"I will, Massa Tom!" exclaimed the colored man, earnestly, "an'
+if I can't do it alone, I'll get Boomerang t' help. Once let dat
+ar' mule git his heels on a pusson, an' dat pusson ain't goin' t'
+come bodderin' around any mo'--that is, not right away."
+
+"I believe you, Rad. Well, keep a lookout for him, and don't
+let him in," and with that Tom entered the house to think over
+matters. They were beginning to assume an aspect he did not
+altogether like. Not that Tom was afraid of danger, but he
+preferred to meet it in the open, and the warning, or threat, of
+the mysterious man disquieted him.
+
+When Mr. Swift came home, a little later, his son told him of
+the midnight interview with Mr. Jenks, for, up to this time, the
+aged inventor was unaware of it, and Tom also gave an account of
+the diamonds, speaking of their value.
+
+"And do you propose to go to Phantom Mountain, in search of the
+makers of these gems, Tom?" asked Mr. Swift.
+
+"I had about decided to do so, dad."
+
+"And you're going in the Red Cloud?'
+
+"Yes."
+
+"Who are going with you?"
+
+"Well, Mr. Jenks will go, of course, and I've no doubt but that
+if I mention the prospective trip to Mr. Damon, that he'll bless
+his skating cap, or something like that, and come along."
+
+"I suppose so, Tom, and I'd like to have you take him. But I
+think you'll need some one else."
+
+"Because, from what you have told me, you are going out to a
+dangerous part of the country, and you may have to deal with
+unscrupulous men. Three of you are hardly enough to cope with
+them. You ought to have at least another member of your party. If
+I was not busy on my invention of a new wireless motor I would go
+along, but I can't leave. You might take Mr. Jackson."
+
+"No, you need him here to help you, dad."
+
+"How about Eradicate?"
+
+Tom smiled.
+
+"Rad would get homesick for his mule Boomerang, and I'd have to
+bring him back just when we'd found the diamonds," replied the
+young inventor. "No, we'll have to think of some one else. I'll
+ask Mr. Damon, and then I'll consider matters further. I expect
+to see Mr. Jenks to-night, and he may have some one in mind."
+
+"Perhaps that will be a good plan. Well, Tom, I trust you will
+take good care of yourself, and not run into unnecessary danger.
+Is the Red Cloud in good shape for the voyage?"
+
+"It needs looking over. I'm going to get right at it."
+
+"It's a pretty indefinite sort of a quest you're going on, Tom,
+my son. How do you expect to find Phantom Mountain?"
+
+"Well, it's going to be quite a task. In the first place we'll
+head for Leadville, Colorado, and then we'll go to Indian Ridge
+and make some inquiries. We may get on the track of the place
+that way. If we don't, why I'll take the airship up as high as is
+necessary and sort of prospect until we see that big cliff that's
+shaped like a head. That will give us something to go by."
+
+"Well, do the best you can. If you can discover the secret of
+making diamonds it will be a valuable one."
+
+"I guess it will, dad; and Mr. Jenks is entitled to know it,
+for he paid his good money to that end. He has promised to go
+halves with me, as payment for the use of the airship, and I must
+say the two diamonds he gave me last night have proved very
+valuable."
+
+"Two diamonds, Tom? You only showed me one, an uncut gem"; and
+Mr. Swift looked at his son.
+
+"Oh, the other--er--the other is--I left it with a jeweler,"
+and Tom blushed a trifle, as he thought of the present he
+contemplated making to Mary Nestor.
+
+That afternoon, as Tom was out in the shed of the Red Cloud
+looking over the airship, to see what would be necessary to do to
+it in order to get it in shape for a long trip, he heard voices
+outside.
+
+"Yes--yes, I know the way in perfectly well," he caught. "You
+needn't bother to come, my good fellow. Just step this way, and
+I'll show you something worth seeing."
+
+"I wonder if it's that mysterious man coming back?" thought
+Tom. He dropped the tool he was using, and hurried to the door.
+As he approached it he heard the voice continue.
+
+"Why bless my shoe laces, Mr. Parker! You'll see a wonderful
+airship, I promise you. Wonderful! Bless my hatband, but I hope
+Tom is here!"
+
+"Mr. Damon!" exclaimed our hero, as he recognized the tones of
+his eccentric friend. "But who is with him?"
+
+A moment later he caught sight of the gentleman who was always
+blessing himself, or something. Behind him stood another man,
+whose features Tom could not see plainly.
+
+"Hello, Tom Swift!" called Mr. Damon. "Looking over the Red
+Cloud, eh? Does that mean you're off on another trip?"
+
+"I guess it does," answered the lad.
+
+"Where to this time? if I may ask."
+
+"I'm thinking of going off to the mountains to find a band of
+men engaged in making diamonds," replied Tom.
+
+"Making diamonds! Bless my finger ring! Making diamonds! A trip
+to the mountains! Bless my disposition! but do you know I'd like
+to go with you!"
+
+"I was thinking of asking you, Mr. Damon."
+
+"Were you? Bless my heart, I'm glad you thought of me. You
+don't by any possible chance want another person; do you?"
+
+"We were thinking of having four in the party, Mr. Damon," and
+Tom wondered who was with his eccentric friend.
+
+"Then bless my election ticket! This is the very chance for
+you, Mr. Parker!" cried Mr. Damon. "Will you go with us? It will
+be just what you need," and Mr. Damon stepped aside, revealing to
+Tom the features of Mr. Ralph Parker, the scientist who had
+correctly predicted the destruction of Earthquake Island.
+
+
+
+
+CHAPTER VII--MR. PARKER PREDICTS
+
+
+Tom Swift was a most generous lad, but when he saw that Mr.
+Damon had with him Mr. Parker, the gloomy scientist, who seemed
+to take delight in predicting disasters, our hero's spirits were
+not exactly of the best. He would have much preferred not to take
+Mr. Parker on the quest for the diamond makers, but, since Mr.
+Damon had mentioned it, he did not see how he could very well
+refuse.
+
+"But perhaps he won't care to go," thought Tom.
+
+He was undeceived a moment later, however, for the scientist
+remarked:
+
+I am very glad to meet you once more, Mr. Swift. I have
+scarcely thanked you enough for what you did for us in erecting
+your wireless station on Earthquake Island, which, as you recall,
+I predicted would sink into the sea. It did, I am glad to say,
+not because I like to see islands destroyed, but because science
+has been vindicated. Now I have just heard you remark that you
+are about to set off to the mountains in search of some men who
+are making diamonds. I need hardly state that this is utterly
+useless, for no diamonds, commercially valuable, can be made by
+men. But the trip may be valuable in that it will permit me to
+demonstrate some scientific facts.
+
+"Therefore, if you will permit me, I will be very glad to
+accompany you and Mr. Damon. I shall be delighted, in short, and
+I can start as soon as you are ready."
+
+"There's no hope for it!" thought Tom, dismally. "I suppose
+he'll wake up every morning, and predict that before night the
+world will come to an end, or he'll prophesy that the airship
+will blow up, and vanish, when about seven miles above the
+clouds. Well, there's no way out of it, so here goes."
+
+Thereupon Tom welcomed the scientist as cordially as he could,
+and invited him to form one of the party that would set off in
+the airship to search for Phantom Mountain.
+
+"Bless my jewelry box!" exclaimed Mr. Damon, when this
+formality was over. "Tell me more about it, Tom."
+
+Which our hero did, stating the need of maintaining secrecy on
+account of the danger to Mr. Jenks. Mr. Damon and Mr. Parker both
+agreed to say nothing about the matter, and then the scientist
+became much interested in the Red Cloud, which he closely
+examined. He even complimented Tom on the skill shown in making
+it, and, contrary to our hero's expectation, did not predict that
+it would blow up the next time it was used.
+
+"How did you happen to arrive just at this time, Mr. Damon?"
+asked Tom.
+
+"It was partly due to Mr. Parker," was the answer. "I had not
+seen him since we were rescued from the island, until a few days
+ago he called on me at my home. I happened to mention that you
+lived near here, and suggested that he might like to see some of
+your inventions. He agreed, and we came over in my auto. And now,
+bless my liver-pin! I find you about to start off on another
+trip."
+
+"And have you fully decided to go with me?" asked Tom. "There
+may be danger, and I don't like the way that mysterious man
+behaved."
+
+"Oh, bless my revolver!" cried Mr. Damon. "I'm used to danger
+by this time. Of course I'm going, and so is Mr. Parker. Do you
+know," and the man, who was always blessing something, came
+closer to the lad, and whispered: "Do you know, Tom, Mr. Parker
+is a very peculiar individual."
+
+"I'm sure of it," answered the young inventor, looking at the
+gentleman in question, who was then inside the airship cabin.
+
+"But he's all right, even if he is predicting unpleasant
+things," went on Mr. Damon. "I think we'll get better acquainted
+with him after a bit."
+
+"I hope so," agreed Tom, but he did not realize then how close
+his companionship with Mr. Parker was to be, nor what dangers
+they were to share later.
+
+The friends talked at considerable length of the prospective
+trip, and Tom, by this time, had ascertained what needed to be
+done to the airship to get it in shape to travel. It would take
+about a week, and, in the meanwhile, Mr. Damon would go home and
+get his affairs in order for the voyage. Tom's father was
+introduced to Mr. Parker, and, the former, finding that the
+scientist held some views in common with him, invited the gloomy
+predictor to remain at the Swift home until the Red Cloud was
+ready to sail. Tom could not repress a groan at this, but he
+decided he would have to make the best of it.
+
+Mr. Damon left for home that afternoon, promising to be on hand
+at the time set to start for Phantom Mountain.
+
+Tom was up waiting for Mr. Jenks at twelve o'clock that night.
+Shortly after the hour he saw a dark figure steal into the
+orchard. At first he feared lest it might be one of the spies who
+were, he was now convinced, on the trail of the man who was
+seeking to discover the secret of the diamond makers. But a
+whistle, which came to the lad's ear a moment later (that being a
+signal Mr. Jenks had agreed to sound), told Tom that it was none
+other than the visitor he expected.
+
+"All right, Mr. Jenks, I'm here," called Tom, cautiously. "Come
+over this way," and he went out from the shadow of the house,
+where he had been waiting, and met the men. "We'll go into my
+private work-shop," the youth added, leading the way.
+
+"Have you decided to go with me?" asked Mr. Jenks, in an
+anxious whisper. "Did you find the diamonds to be real ones?"
+
+"I did; and I'm going," spoke Tom.
+
+"Good! That relieves my mind. But we are still in danger. I was
+followed by my shadower to-day, and only succeeded in shaking him
+off just before coming here. I don't believe he knows what I am
+about to do."
+
+"Oh, yes he does," said Tom.
+
+"He does? How?"
+
+"Because he was here, and warned me against you!"
+
+"You don't mean it! Well, they are getting desperate! We must
+be on our guard. What sort of a man was he?"
+
+Tom described the fellow, and Mr. Jenks stated that this
+tallied with the appearance of the person who had been shadowing
+him.
+
+"But we'll fool them yet!" cried Tom, who had now fully entered
+into the spirit of the affair. "If they can follow us in the Red
+Cloud they're welcome to. I think we'll get ahead of them."
+
+He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed
+that it would add to the strength of the party to take these two
+gentlemen along.
+
+"Though I can't say I care so much for Mr. Parker," he added.
+"But now as to ways and means. When can we start?"
+
+Thereupon he and Tom talked over details in the seclusion of
+the little office, and arranged to leave Shopton in about a week.
+In the meanwhile the airship would be overhauled, stocked with
+supplies and provisions, and be made ready for a swift dash to
+the mountains.
+
+"And now I must be going," said Mr. Jenks. "I have a great deal
+to do before I can start on this trip, and I hope I am not
+prevented by any of those men who seem to be trailing me."
+
+"How could they prevent you?" Tom wanted to know.
+
+"Oh, there are any number of ways," was the answer. "But I'm
+glad you found that my diamonds were real. We'll soon have
+plenty, if all goes well."
+
+As Mr. Jenks left the shop, he started back, in some alarm.
+
+"What's the matter?" asked Tom.
+
+"Over there--I thought I saw a figure sneaking along under the
+trees--that man--perhaps--"
+
+"That's Eradicate, our colored helper," replied Tom, with a
+laugh. "I posted him there to see that no strangers came into the
+orchard. Everything all right, Rad?" he asked, raising his voice.
+
+"Yais, sah, Massa Tom. Nobody been around yeah this night."
+
+"That's good. You can go to bed now," and Eradicate, yawning
+loudly, went to his shack. A little later Tom sought his own
+room, Mr. Jenks having hurried off to town, where he was
+boarding.
+
+The next few days saw Tom busily engaged on the airship, making
+some changes and a few repairs that were needed. His father,
+Eradicate and Mr. Jackson helped him. As for Mr. Parker, the
+scientist, he went about the place, being much interested in the
+various machines which Tom or Mr. Swift had patented.
+
+At other times the scientist would stroll about the extensive
+grounds, making what he said were "observations." One afternoon
+Tom saw him, apparently much excited, kneeling down back of a
+shed, with his ear to the ground.
+
+"What is the matter?" asked the lad, thinking perhaps Mr.
+Parker might be ill.
+
+"Have you ever had any earthquakes here, Tom Swift?" asked the
+scientist, quietly.
+
+"Earthquakes? No. We had enough of them on the island."
+
+"And you are going to have one here, in about two minutes!"
+cried Mr. Parker. "I predict that this place will be shaken by a
+tremendous shock very soon. We had all better get away from the
+vicinity of buildings."
+
+"What makes you think there will be an earthquake?" asked Tom.
+
+"Because I can hear the rumbling beneath the ground at this
+very minute. It is increasing in volume, showing that the tremors
+are working this way. There will soon be a great subterranean
+upheaval! Listen for yourself."
+
+Tom cast himself down on the grass. Placing his ear close to
+the ground he did hear a series of dull thuds. He arose, not a
+little alarmed. There had never been any earthquakes in Shopton,
+yet he had great respect for Mr. Parker's scientific attainments.
+
+Just then Eradicate Sampson came along. He saw Tom and Mr.
+Parker lying flat on the ground, and surprise showed on his
+honest, black face.
+
+"Fo' de land sakes!" cried Eradicate. "What am de mattah now,
+Massa Tom?"
+
+"Earthquake coming," answered Tom, briefly. "Better get away
+from the buildings, Rad. They might fall!" Tom's face showed the
+alarm he felt. What would happen to all of his valuable
+machines--to the Red Cloud?
+
+"Earthquake?" murmured Eradicate, and he, too, cast himself
+down to listen. A moment later he arose with a laugh.
+
+"What's the matter?" cried Tom.
+
+"Why, dat ain't no earthquake!" declared the colored man.
+
+"No. Then perhaps you know what it is," said Mr. Parker,
+somewhat sharply.
+
+"Course I knows what it am," answered Eradicate, with dignity.
+"Dat noise am my mule Boomerang, kickin' in his stable, on
+account oh me not feedin' him yet. Dat's what it am. I'se gwine
+right now t' gib him his oats, and den yo' see dat de noise stop.
+Boomerang allers kick dat way when he's hungry. I show yo'!"
+
+And, sure enough, when Eradicate had gone to the mule's stable,
+which was near where Mr. Parker had heard the mysterious sounds,
+they immediately ceased.
+
+"Dat mule was all de earthquake dere was around here," said the
+colored man as he came out.
+
+Mr. Parker walked away, saying nothing, and Tom did not make
+any comments--just then.
+
+
+
+
+CHAPTER VIII--OFF FOR THE WEST
+
+
+It was a great relief to Tom, to find that there was no danger
+from an earth tremor. Now that he had made up his mind to go in
+search of the diamond makers, he wanted nothing to interfere with
+it. Lest the feelings of Mr. Parker might be hurt by the mistake
+he had made, the young inventor cautioned Eradicate not to say
+anything more about the matter.
+
+"'Deed an' I won't," the colored man promised. "I'se only too
+glad dere wa'n't no earthquake, dat's what I is."
+
+As for Mr. Parker, he did not appear much put out by his error
+in predicting.
+
+"I am sure that what I heard was a tremor, due to some distant
+earthquake shock," he said. "The mule's kicking was only a
+coincidence."
+
+And Tom let him have his way about it. The week was drawing to
+a close, and the Red Cloud was nearly in shape for the voyage. At
+almost the last minute Tom found that he needed some electrical
+apparatus for the airship, and as he had to go to Chester for it,
+he decided he would make the trip in his monoplane, and, while in
+the city, would also get the diamond pin he was having made for
+Mary Nestor.
+
+He started off early one morning, in the swift little craft
+Butterfly, and soon had reached Chester. The diamond brooch was
+ready for him.
+
+"It is one of the most beautiful stones we have ever set," the
+diamond merchant told him. "Don't forget, if you find any more,
+Mr. Swift, to let us have a chance to bid on them."
+
+"I may," Tom promised, rather indefinitely. Then, having
+purchased his electrical supplies, he made a quick trip to
+Shopton, stopping on the way to call on Miss Nestor.
+
+"Why Tom, I'm delighted to see you!" cried the girl, blushing
+prettily. "Did you come for some apple turnovers?" and she
+laughed, as she referred to a call Tom had once paid, when a new
+cook had been engaged, and when the pastry formed a feature of
+the meal.
+
+"No turnovers this time," said the young inventor. "I came to
+wish you many happy returns of the day."
+
+"Oh, you remembered my birthday! How nice of you!"
+
+"And here is something else," added our hero, rather awkwardly,
+as he handed her the diamond pin.
+
+"Oh, Tom! This for me! Oh, it's too lovely--it's far too much!"
+
+"It isn't half enough!" he declared, warmly. "Oh, what a large
+diamond!" Mary cried as she saw the sparkling stone. "I never saw
+one so large and beautiful!"
+
+"It's just as easy to make them large as small," explained Tom.
+
+"Make them?" she looked the surprise she felt.
+
+"Yes, I'm about to start for the place where diamonds are
+made."
+
+"Oh, Tom! But isn't it dangerous? I mean won't you have to go
+to some far country--like Africa--to get to where diamonds are
+made?"
+
+"Well, we are going on quite a trip, but not as far as that.
+And as for the danger--well, we'll have to take what comes," and
+he told her something of the proposed quest.
+
+"Oh, it sounds--sounds scary!" Mary exclaimed, when she had
+heard of Mr. Jenks' experience. Do be careful, Tom!"
+
+"I will," he promised, and, somehow he was glad that she had
+cautioned him thus--and in such tones as she had used. For Mary
+Nestor was a girl that any young chap would have been glad to
+have manifest an interest in him.
+
+"Well, I guess I'll have to say good-by," spoke Tom, at length.
+"We expect to start in a couple of days, and I may not get
+another chance to see you."
+
+"Oh, I--I hope you come back safely," faltered Mary, and then
+she held out her hand, and Tom--well, it's none of our affair
+what Tom did after that, except to say that he hurried out,
+fairly jumped into his monoplane, and completed the trip home.
+
+As the Red Cloud has been fully described in the volume
+entitled "Tom Swift and His Airship," we will not go into details
+about it now. Sufficient to say that it was a combination of a
+biplane and dirigible balloon. It could be used either as one or
+the other, and the gas-bag feature was of value when the wind was
+too great to allow the use of the planes, or when the motive
+power, for some reason stopped. In that event the airship could
+remain suspended far above the clouds if necessary. There was
+provision for manufacturing the gas on board.
+
+The Red Cloud was fitted up to accommodate about ten persons,
+though it was seldom that this number was carried. Two persons
+could successfully operate the machinery. There were sleeping
+berths, and in the main cabin a sitting-room, a dining-room, and
+a kitchen. There was also the motor compartment, and a steering
+tower, from which the engines could be controlled.
+
+It was in this craft that the seekers after the diamond makers
+proposed undertaking the trip. Mr. Damon came on from his home in
+Waterfield about two days before the date set to leave, and Mr.
+Jenks, had, three days before this, taken up his abode at the
+Swift home. Mr. Parker, as has been stated, was already there,
+and he had put in his time making a number of scientific
+observations, though he had made no more predictions.
+
+Nothing more had been seen of the mysterious man who had warned
+Tom, and the young inventor and Mr. Jenks began to hope that they
+had thrown their enemies off the track.
+
+"Though I don't imagine they'll give up altogether," said Mr.
+Jenks. "They're too desperate for that. We'll have trouble with
+them yet."
+
+"Well, it can't be helped," decided Tom. "We'll try and be
+ready for it, when it comes," and then, dismissing the matter
+from his mind, he busied himself about the airship.
+
+The food and supplies had all been put aboard, and they
+expected to start the next morning. In order to make sure that
+any stones which they might succeed in getting from the diamond
+makers were real gems, a set of testing apparatus was taken
+along. Mr. Parker had had some experience in this line, and, in
+spite of the fact that he might make direful predictions, Tom was
+rather glad, after all, that the scientist was going to accompany
+them.
+
+"But what is worrying me," said Mr. Damon, "is what we are
+going to do after we get to Phantom Mountain. What are your
+plans, Mr. Jenks? Will you go in, and demand your share of the
+diamond-making business?"
+
+"I have a right to it, as I invested a large sum in it, and I
+am entitled to more than a half-share. But, of course, I can't
+say what I'll do until I get there. We may have to act very
+secretly."
+
+"I'm inclined to think we will," said Tom. "My plan would be to
+gain access to the cave, if possible, and watch them at work. We
+might be able to discover the secret of making diamonds, and,
+after all, that's what you want, isn't it, Mr. Jenks?"
+
+"Yes, I paid my money for the secret, and I ought to have it.
+If I can get it quietly, so much the better. If not, I'll fight
+for my rights!" and he looked very determined.
+
+"Bless my powder horn!" cried Mr. Damon. "That's the way to
+talk! And so we're to go cruising about in the air, looking for a
+mountain shaped like a man's head."
+
+"That's it," a greed Mr. Jenks, "and when we find it we will be
+near Phantom Mountain, and the diamond makers."
+
+The final details were completed that night. The last of the
+supplies had been put aboard, the larder was well stocked, the
+diamond testing apparatus was stored safely away, and all that
+remained was for the adventurers to board the Red Cloud in the
+morning, and soar away.
+
+That night Tom was uneasy. Several times he got up, and looked
+toward the shed where the airship was stored. He could not rid
+himself of the idea that the men to whose interest it was that
+the diamond-making secret remain undiscovered, might attempt to
+wreck the airship before the start. Consequently both Eradicate
+Sampson and Engineer Jackson were on guard. Tom looked from his
+window, to the shed where the Red Cloud was housed. He saw
+nothing to cause him any uneasiness.
+
+"I guess I'm just nervous," he mused. "But, all the same, I'll
+be glad when we've started."
+
+They were all up early the next morning, Mr. Damon beginning
+the day by blessing the sunrise, and many other things that
+struck his fancy. The airship was wheeled out of the shed, and
+Tom gave her a final inspection.
+
+"It's all right," he declared. "All aboard!"
+
+"Now, do be careful," begged Mr. Swift. "Don't take too many
+chances, Tom."
+
+"I'll not."
+
+The adventurers were in the forward part of the ship, and Tom
+had taken his place at the wheels and levers in the pilot house.
+As he was about to start the motor he looked toward the road, and
+saw a horse and carriage. In the vehicle was a girlish figure, at
+the sight of which Tom blushed and smiled. He waved his hand.
+
+"I came to wish you good luck!" cried Mary Nestor, for it was
+she in the carriage.
+
+"Thanks!" cried Tom, leaning from the window of the pilot
+house. "It was good of you to get up so early."
+
+"Oh. I'm always up early," she informed him.
+
+"Look out that the motor doesn't scare your horse," Tom warned
+her.
+
+"Old Dobbin doesn't mind anything," was her answer. "I'll see
+that he doesn't run away with me, as long as you're not on earth
+to rescue me. Good-by, Tom!"
+
+"Good-by!" he called, and then he pulled the lever that set in
+motion the motor, and whirled the great propellers about. They
+whizzed around with a roar, and the Red Cloud, shivering and
+trembling with the vibration, rose in the air like some great
+bird.
+
+"We're off for the West and Phantom Mountain!" called Tom to
+his companions.
+
+As the airship soared upward, Eradicate Sampson ran forward
+from where he had been standing near his mule Boomerang. He waved
+his hands, and shouted something.
+
+"Bless my hatband! What does he want?" asked Mr. Damon,
+watching him curiously.
+
+"It sounds as if he were calling to us to come back," spoke Mr.
+Parker.
+
+"It's too late now," decided Tom. "Maybe he forgot to tell us
+good-by," but, he felt a vague wonder at Eradicate's odd motions;
+for the colored man was pointing toward the stern of the airship,
+as if there was something wrong there. But the Red Cloud soared
+on.
+
+
+
+
+CHAPTER IX--A WARNING BY WIRELESS
+
+
+Rapidly the airship ascended, and, when it was high over the
+town of Shopton, Tom headed the craft due west. Looking down he
+tried to descry Mary Nestor, in her carriage, but the trees were
+in the way, their interlocking branches hiding the girl. Tom did
+see crowds of other persons, though, thronging the streets of
+Shopton, for, though the young inventor had made many flights,
+there was always a novelty about them, that brought out the
+curious.
+
+"A good start, Tom Swift," complimented Mr. Parker. "Is it
+always as easy as this?"
+
+"Starting always is," was the answer, "though, as the Irishman
+said, coming down isn't sometimes quite so comfortable."
+
+"Bless my gizzard! That's so," cried the eccentric Mr. Damon.
+"Can we vol-plane to earth in the Red Cloud, Tom?"
+
+"Yes, but not as easily as in the Butterfly. However I hope we
+will not have to. Now, Mr. Damon, if you will just take charge of
+the steering apparatus for a minute, I want to go aft."
+
+"What for?"
+
+"I wish to see if everything is all right. I can't imagine why
+Eradicate was making those queer motions."
+
+Mr. Damon, who knew how to operate the Red Cloud, was soon
+guiding her on the course, while Tom made his way to the rear
+compartments, through the motor room, where the stores of
+supplies and food were kept. He made a careful examination,
+looking from an after window, and even going out on a small, open
+platform, but could discover nothing wrong.
+
+"I guess Rad was just capering about without any special
+object," mused Tom, but it was not long after this that they
+learned to their dismay, that the colored man had had a method in
+his madness.
+
+On his way back through the motor room Tom looked to the
+machinery, and adjusted some of the auxiliary oil feeders. The
+various pieces of apparatus were working well, though the engine
+had not yet been speeded up to its limit. Tom wanted it to "warm-up"
+first.
+
+"Everything all right?" asked Mr. Damon, as Tom rejoined them
+in the pilot house, which was just forward of the living room in
+the main cabin.
+
+"Yes, I can't imagine what made Rad act that way. But I'll set
+the automatic steering gear now, Mr. Damon, and then you will be
+relieved."
+
+Mr. Jenks was gazing off toward the west--to where he hoped to
+discover the secret of Phantom Mountain.
+
+"How do you like it?" asked Tom.
+
+"It's great," replied the diamond man. "I've never been in an
+airship before, and it's different than what I expected; but it's
+great! It's the only craft that will serve our purpose among the
+towering mountain peaks, where the diamond makers are hidden. I
+hope we can find them."
+
+In a little while the Red Cloud was skimming along at faster
+speed, guided by the automatic rudders, so that no one was needed
+in the pilot house, since there was no danger of collisions.
+Airships are not quite numerous enough for that, yet, though they
+may soon become so.
+
+Tom and the others devoted several hours to arranging their
+staterooms and bunks, and getting their clothing stowed away, and
+when this was done Mr. Parker and Mr. Jenks sat gazing off into
+space.
+
+"It's hard to realize that we are really in an airship,"
+observed the diamond man. "At first I thought I would be
+frightened, but I'm not a bit. It doesn't seem as if anything
+could happen."
+
+"Something is likely to happen soon," said Mr. Parker,
+suddenly, as he gazed at some weather instruments on the cabin
+wall.
+
+"Bless my soul! Don't say that!" cried Mr. Damon. "What is it?"
+
+"I think, from my observations, that we will soon have a
+hurricane," said the scientific man. "There is every indication
+of it"'; and he seemed quite delighted at the prospect of his
+prediction coming true.
+
+"A hurricane!" cried Mr. Damon. "I hope it isn't like the one
+that blew us to Earthquake Island."
+
+"Oh, I think there will be no danger," spoke Tom. "If it comes
+on to blow we will ascend or descend out of the path of the
+storm. This craft is not like the ill-fated Whizzer. I can more
+easily handle the Red Cloud; even in a bad storm."
+
+"I'm glad to hear that," remarked Mr. Jenks. "It would be too
+bad to be wrecked before we got to Phantom Mountain."
+
+"Well, I predict that we will have a bad storm," insisted Mr.
+Parker, and Tom could not help wishing that the scientist would
+keep his gloomy forebodings to himself.
+
+However the storm had not developed up to noon, when Tom, with
+Mr. Damon's help, served a fine meal in the dining-room. In the
+afternoon the speed of the ship was increased, and by night they
+had covered several hundred miles. Through the darkness the Red
+Cloud kept on, making good time. Tom got up, occasionally, to
+look to the machinery, but it was all automatically controlled,
+and an alarm bell would sound in his stateroom when anything went
+wrong.
+
+"Bless my napkin!" exclaimed Mr. Damon the next morning, as
+they sat down to a breakfast of fruit, ham and eggs and fragrant
+coffee, "this is living as well as in a hotel, and yet we are--how
+far are we above the earth, Tom?" he asked, turning to the
+young inventor.
+
+"About two miles now. I just sent her up, as I thought I
+detected that storm Mr. Parker spoke of."
+
+"I told you it would come," declared the scientist, and there
+was a small hurricane below them that morning, but only the lower
+edge of it caught the Red Cloud, and when Tom sent her up still
+higher she found a comparatively quiet zone, where she slid along
+at good speed.
+
+That afternoon Tom busied himself about some wires and a number
+of complicated pieces of apparatus which were in one corner of
+the main cabin.
+
+"What are you doing now?" asked Mr. Jenks, who had been talking
+with Mr. Parker, and showing that scientist some of the
+manufactured diamonds.
+
+"Getting our wireless apparatus in shape," answered the lad. "I
+should have done it before, but I had so much to do that I
+couldn't get at it. I'm going to send off some messages. Dad will
+want to know how we are doing."
+
+As he worked away, he also made up his mind to send another
+message, in care of his father, for there was a receiving station
+in the Swift home. And to whom this message was addressed Tom did
+not say, but we fancy some of our readers can guess.
+
+Finally, after several hours of work, the wireless was in shape
+to send and receive messages. Tom pulled over the lever, and a
+crackling sound was heard, as the electricity leaped from the
+transmitters into space. Then he clamped the receiver on his ear.
+
+"All ready," he announced. "Has anybody any messages they wish
+sent?" For, with the courtesy of a true host he was ready to
+serve his guests before he forwarded his own wireless notes.
+
+"Just tell my wife that I'm enjoying myself," requested Mr.
+Damon. "Bless my footstool! But this is great! We're off the
+earth yet, connected with it."
+
+Mr. Jenks had no one to whom he wanted to send any word, but
+Mr. Parker wish to wire to a fellow scientist the result of some
+observations made in the upper air.
+
+Tom noted all the messages down, and then, when all was in
+readiness he began to call his home station. He knew that either
+his father or Mr. Jackson, the engineer, could receive the
+wireless.
+
+But, no sooner had the young inventor sent off the first few
+dots and dashes representing "S. I."--his home station call--than
+he started and a look of surprise came over his face.
+
+"They're calling us!" he exclaimed.
+
+"Who is?" asked Mr. Jenks.
+
+"My house--my father. He--he's been trying to get us ever since
+we started, but I didn't have the wireless in shape to receive
+messages. Oh, I hope it's not too late!"
+
+"Too late! Bless my soul, too late for what?" gasped Mr. Damon,
+somewhat alarmed by Tom's manner.
+
+The lad did not answer at once. He was intently listening to a
+series of dots and dashes that clicked in the telephone receiver
+clamped to his left ear. On his face there was a look of
+worriment.
+
+"Father has just sent me a message," he said. "It's a warning
+flashed through space! He's been trying to get it to me since
+yesterday!"
+
+"What is it?" asked Mr. Jenks, rising from his seat.
+
+"The mysterious man is aboard the airship--hidden away!" cried
+Tom. "That's what Eradicate was trying to call to our attention
+as we started off. Eradicate saw his face at a rear window, and
+tried to warn us! The mysterious man is a stowaway on board!"
+
+
+
+
+CHAPTER X--DROPPING THE STOWAWAY
+
+
+Tom's excited announcement startled Mr. Damon and the others as
+much as if the young inventor had informed them that the airship
+had exploded and was about to dash with them to the earth. The
+men leaped to their feet, and stared at the lad.
+
+"A stowaway on board!" cried Mr. Damon.
+"Bless my soul! How did he--"
+
+"Are you sure that message is straight?" asked Mr. Jenks. "Did
+Eradicate see the man?"
+
+"He says he did," answered Tom. "The man is hidden away on
+board now--probably among the stores and supplies."
+
+"Bless my tomato sauce!" exploded Mr. Damon. "I hope he doesn't
+eat them all up!"
+
+"We must get him out at once!" declared Mr. Jenks.
+
+"I knew something would happen on this voyage," came from Mr.
+Parker. "I predicted it from the first!"
+
+Tom thought considerable, but he did not answer the scientist
+just then. Another communication was coming to him by wireless.
+He listened intently.
+
+"Father says," the lad told his companions "that Eradicate only
+had a glimpse of the man at the last moment. He was looking from
+the rear storeroom window--he's the same man who called on me
+that time--Rad remembers him very well."
+
+"Bless my shoes! What's to be done?" inquired Mr. Damon,
+looking around helplessly.
+
+"We must get him out, that's all," decided Mr. Jenks; with
+vigor. "Get him out and drop him overboard!"
+
+"Drop him overboard!" cried Mr. Parker, in horror.
+
+"Not exactly, but get rid of him," proceeded the diamond
+seeker. "That man is one of my enemies. He has been sent by the
+band of diamond makers hidden among the mountains, to spy on me,
+and, if possible, prevent me from seeking to discover their
+secret. He tried to work on Tom's Swift's fears, and frighten him
+from using his airship on this quest. Then, when he failed, the
+man must have sneaked into the shed, and hidden himself in the
+ship. We must get rid of him, or he may wreck the Red Cloud!"
+
+"That's so!" cried Tom. "We must try to capture him. I think we
+had better--" the lad paused, and again listened to the wireless
+message. "Father says Eradicate saw the man have a gun, so we
+must be careful," the young inventor translated the dots and
+dashes.
+
+"Bless my powder horn!" exploded Mr. Damon.
+
+"We shall have to proceed cautiously then," spoke Mr. Jenks.
+"If he is like any others in the gang he is a desperate man."
+
+"Better sneak up on him then, if we can," proposed Mr. Parker.
+"There are enough of us to cope with one man, even if he is
+armed. You have weapons aboard, haven't you?" he inquired of Tom.
+
+"Yes," was the hesitating answer, "but I don't want to use them
+if I can help it. Not only because of the danger, and a dislike
+of shedding blood, but because a stray bullet might pierce the
+gas bag and damage the ship."
+
+"That's so," agreed Mr. Jenks. "Well, I guess if we go at it
+the right way we can capture him without any shooting. But we
+must talk more quietly--we ought to have whispered--he may have
+heard us."
+
+"I don't think so," replied Tom. "The storeroom is far enough
+off so that he couldn't hear us. Besides, the motor makes such a
+racket that he couldn't distinguish what we were talking about,
+even if he heard our voices. So, unless he heard the wireless
+working, and suspects something from that, he probably doesn't
+know that we are aware of his presence aboard."
+
+"But why do you think he has remained quiet all this while,
+Tom?" asked Mr. Damon.
+
+"Probably he wants to wait until the ship is farther out west,"
+suggested Mr. Jenks. "Then he will be nearer his friends, and can
+get help, if he needs it."
+
+"And do you really believe he would destroy the Red Cloud?"
+asked Mr. Parker.
+
+"I think that all he is waiting for is a favorable chance,"
+declared the diamond seeker. "He would destroy the craft, and us
+too, if he could prevent us from discovering the secret of
+Phantom Mountain, I believe."
+
+"Then we must get ahead of him," decided Tom, quietly. "I have
+just flashed to dad a message, telling him that we will heed his
+warning. Now to capture the stowaway!"
+
+"And while we're about it, give him a good scare when we do get
+him," suggested Mr. Jenks.
+
+"How?" asked Tom.
+
+"Threaten to drop him overboard. Perhaps that will make him
+tell how he happened to get in our ship, and what are the plans
+of the gang of diamond makers. We may get valuable information
+that way."
+
+"I don't believe you can scare such fellows much," was Tom's
+opinion, but it was agreed to try.
+
+"How are you going to capture him?" asked Mr. Parker. "If he
+has a gun it won't be any too easy to go in the storeroom, and
+drag him out."
+
+"We'll have to use a little strategy," decided Tom, and then they
+discussed several plans. The one finally adopted was that Tom and Mr.
+Damon should enter the storeroom, casually, as if in search of food to
+cook for supper. They would discuss various dishes, and Mr. Damon was
+to express a preference for something in the food line, the box
+containing which, was well hack in the room. This would give the two a
+chance to penetrate to the far end of the apartment, without arousing
+the suspicions of the hidden man, who, doubtless, would be listening
+to the conversation.
+
+"And as soon as we get sight of him, you and I will jump right
+at him, Mr. Damon," said Tom. "Jump before he has a chance to use
+his gun. Mr. Jenks and Mr. Parker will be waiting outside the
+room, to catch him if he gets away from us. I'll have some ropes
+ready, and we'll tie him up, and--well, we'll decide later what
+to do with him."
+
+"All right. I'm ready as soon as you are, Tom," said the
+eccentric man. "Come ahead."
+
+They went softly to the storeroom, and listened at the door.
+There was no sound heard save that made by the machinery.
+
+"I wonder if he's really here?" whispered Mr. Damon.
+
+"We'll soon find out," answered Tom. "Let's go in."
+
+They entered, and, in pursuance of their plan, Tom and his
+friend talked of various foods.
+
+"I think I'd like some of that canned lobster, with French
+dressing on," spoke the eccentric man.
+
+"That's away in the back end of the room," said Tom, in a loud
+voice. "It's under a lot of boxes."
+
+"Then I'll help you get it out! Bless my frying pan! but I am
+very fond of lobster!" exclaimed Mr. Damon, in as natural tones
+as was possible under the circumstances.
+
+He and Tom moved cautiously back among the boxes and barrels.
+They were glancing about with eager eyes. Tom switched on an
+electric light, and, the instant he did so, he was aware of a
+movement in a little space formed by one box which was placed on
+top, of two others. The lad saw a dark figure moving, as if to
+get farther out of sight.
+
+"I've got him!" cried Tom, making a dive for the shadow.
+
+A moment later the young inventor was bowled over, as a dark
+figure leaped over his head.
+
+"Catch him, Mr. Damon!" he cried.
+
+"Bless my hatband! I--I--" Mr. Damon's voice ended in a grunt.
+He, too, had been knocked down by the fleeing man.
+
+"Look out, Mr. Jenks!" cried Tom, to warn those on guard at the
+door of the storeroom.
+
+There was the report of a gun, some excited shouts, and when
+Tom could scramble to his feet, and rush out, he beheld Mr.
+Parker calmly sitting on a struggling man, while Mr. Jenks held a
+gun, that was still smoking.
+
+"We caught him!" cried the scientist.
+
+"Anybody hurt?" asked Tom, anxiously.
+
+"No, I knocked up his gun as he fired," explained Mr. Jenks.
+"Where are the ropes, Tom?"
+
+The cords were produced and the man, who had now ceased to
+struggle, was tightly bound. He uttered not a word, but he smiled
+grimly when Mr. Damon remarked:
+
+"I guess I'll go back in the storeroom, Tom, and see how much
+food he ate."
+
+"Oh, I guess he didn't take much," declared the lad. "He wasn't
+there long enough."
+
+"Well, Farley Munson, so it's you, is it?" asked Mr. Jenks, as
+he surveyed the prisoner.
+
+"Do you know him?" asked Tom, in some surprise.
+
+"He was in with the diamond makers," said Mr. Jenks. "He was
+one of those who took me to the secret cave. But it will be the
+last time he ever goes there. How high up are we, Tom?"
+
+"About two miles. Why?"
+
+"I guess that will be far enough to let him fall," went on the
+diamond seeker. "Come on, Mr. Damon, help me throw him overboard!"
+
+"You--you're not going to throw me over--with the airship two
+miles high; are you?" gasped the man.
+
+"Will you tell us what we want to know, if we don't?" asked Mr.
+Jenks.
+
+"What do you want to know?"
+
+"How you got aboard, and what your object was in coming."
+
+"That's easy enough. I had been hanging around the shed for
+several days, watching a chance to get in. Finally I saw it, when
+that colored man went to feed his mule, and I slipped in, and
+hid in the airship. The stores were all in then, and I stowed
+myself away among the boxes. I had food and water, so I didn't
+touch any of yours," and he looked at Mr. Damon, who seemed much
+relieved.
+
+"And what was your object?" demanded Mr. Jenks.
+
+"I wanted to prevent you from going to Phantom Mountain."
+
+"How?"
+
+"By destroying the airship if need be. But I hoped to
+accomplish it by other means. I would have stopped at nothing,
+though, to prevent you. You must keep away from there!"
+
+"And if we refuse?" asked Tom.
+
+"Then you'll have to take what comes!"
+
+"But not from you!" exclaimed Mr. Jenks. "We're going to get
+rid of you."
+
+The man's face showed the alarm he felt.
+
+"Oh, don't worry," said Mr. Jenks, quickly, "we're not going to
+toss you overboard. We're not as desperate as your crowd. But
+we're going to get rid of you, and then go on before you can send
+any word to your confederates. We'll put you off in the most
+lonesome spot we can find, and I guess you'll be some time
+getting back to civilization. By that time we'll have the secret
+of the diamonds."
+
+"You never will!" declared the man, firmly. And he would say
+nothing more, though by threats and promises Mr. Jenks tried to
+get from him something about the men in with him, and where the
+cave of the diamonds was located.
+
+Heavily bound with ropes the man was locked in a small closet,
+to be kept there until a favorable spot was reached for letting
+him go. Mr. Jenks' plan, of dropping him down in some place where
+he would have difficulty in sending on word to his confederates
+was considered a good one.
+
+Three days later, in crossing over a lonely region, near the
+Nebraska National Forest, Farley Munson, which was one of the
+names the spy went by, was dropped off the airship, when it was
+sent down to within a few feet of the earth.
+
+"It will take you some time to get to a telegraph office," said
+Mr. Jenks, as a package of food, and a flask of water was tossed
+down to the stowaway. He shook his fist at those in the airship,
+and shouted after them:
+
+"You'll never discover the secret of Phantom Mountain!"
+
+"Yes, we will," declared Tom, as he sent the Red Cloud high
+into the air again.
+
+
+
+CHAPTER XI--A WEARY SEARCH
+
+
+During the three days when the stowaway had been kept a
+prisoner, the Red Cloud had made good time on her western trip.
+She was now about two hundred and fifty miles from Leadville,
+Colorado, and Tom knew he could accomplish that distance in a
+short time. It was necessary, therefore, since they were so close
+to the place where the real search would begin, to make some more
+definite plans.
+
+"We will need to replenish our supply of gasoline," said Tom,
+shortly after the stowaway had been dropped, and when the young
+inventor had made a general inspection of the airship.
+
+"Is it all gone?" inquired Mr. Damon.
+
+"Not all, but we will soon be in the wildest part of the Rocky
+Mountains, and gasoline is difficult to procure there. So I want
+to fill all our reserve tanks. But I would rather do that before
+we get far into Colorado."
+
+"Why?" inquired Mr. Parker.
+
+"Because airships are not so common but what the appearance of
+one attracts attention. Ours is sure to be talked about, and
+commented on. In that case, in spite of our precaution in putting
+Munson off in this lonely place, word of the Red Cloud being in
+the vicinity of Leadville may reach the diamond makers, and put
+them on their guard. We want to take them unawares if we can."
+
+"That's so," agreed Mr. Jenks. "We had better get our gasoline
+at the first stopping place, then, and proceed with our search.
+Our first object ought to be to look for the landmark--the head
+of stone. Then we can begin to prospect about a bit."
+
+"My idea, exactly," declared Tom. "Well, then, I'll go down at
+the first place we cross, where we can get gasoline, and then
+we'll be in a position to hover in the air for a long time,
+without descending."
+
+The airship kept on her way, traveling slowly the remainder of
+that day, and at dusk, when there was less chance of big crowds
+seeing them, the Red Cloud was sent down on the outskirts of a
+large village. Tom and Mr. Damon went to a supply store, and
+arranged to have a sufficient quantity of the gasoline taken out
+to the airship. It was delivered after dark, and little talk was
+occasioned by the few who were aware of the presence of the
+craft. Then, once more, they went aloft, and Tom sent several
+wireless messages to Shopton, including one to Miss Nestor.
+
+"Please tell my wife that I am well, and that I have a good
+appetite," said Mr. Damon.
+
+Mr. Parker also sent a message to a scientific friend of his, stating
+that he made some observations among the mountains, of the region in
+which the airship then was, and that the indications were that a great
+landslide would soon take place.
+
+"That won't worry us," spoke Tom, "for we'll be far above it."
+
+"I hope we will be near enough to enable me to observe it, and
+make some scientific notes," came from Mr. Parker. "I am positive
+that one of these mountain peaks that we saw to-day will
+disappear in a landslide within a few days. I have an instrument
+somewhat like the one that records earthquakes, and it has been
+acting strangely of late."
+
+Tom wondered what enjoyment Mr. Parker got out of life, when he
+was always looking for some calamity to happen, but the scientist
+seemed to take as much pleasure in his gloomy forebodings now, as
+he had on Earthquake Island.
+
+They reached the vicinity of Leadville the next day, but took
+care to keep high above the city, so that the airship could not
+be observed. With powerful glasses they examined the mountainous
+country, looking for the little settlement of Indian Ridge.
+
+"There it is!" exclaimed Mr. Jenks, just as dusk was settling
+down. I can make out the hotel I stopped at. Now we can really
+begin our search. The next thing is to find the stone head, and
+then, I think, I will have my bearings."
+
+"We'll begin the hunt for that landmark in the morning," said
+Tom.
+
+High in the air hovered the Red Cloud. At that distance above
+the earth she must have looked like some great bird, and the
+adventurers thought it unlikely that any one in the vicinity of
+Leadville would observe them.
+
+The quest for the great mountain peak, that looked like a stone
+head, was under way. Back and forth sailed the airship. Sometimes
+she was enveloped in fog, and no sight could be had of the earth
+below. At other times there were rain storms, which likewise
+prevented a view. Mr. Parker was on the lookout for his predicted
+mountain landslide, but it did not occur, and he was much
+disappointed.
+
+"It's queer I can't pick out that landmark," said Mr. Jenks
+after two days of weary searching, when their eyes were strained
+from long peering through telescopes. "I'm sure it was around
+Indian Ridge, yet we've covered almost all the ground in this
+neighborhood, and I haven't had a glimpse of it."
+
+"Perhaps it was destroyed in a landslide, or some cataclysm of
+nature," suggested Mr. Parker. "That is very possible."
+
+"If that's the case we're going to have a hard time to locate
+the cave of the diamond makers," answered Mr. Jenks, "but I hope
+it isn't so."
+
+They continued the search for another day, and then Tom, as
+they sat in the comfortable cabin of the airship that night,
+hovering almost motionless (for the motor had been shut down)
+made a proposition.
+
+"Why not descend in some secluded place," he suggested, "and
+wander around on foot, making inquiries of the miners. They may
+know where the stone head is, or they may even know about Phantom
+Mountain."
+
+"Good idea," spoke Mr. Jenks. "We'll do it."
+
+Accordingly, the next morning, the Red Cloud was lowered in a
+good but lonely landing place, and securely moored. It was in a
+valley, well screened from observation, and the craft was not
+likely to be seen, but, to guard against any damage being done to
+it by passing hunters or miners, Mr. Parker and Mr. Damon agreed
+to remain on guard in it, while Tom and Mr. Jenks spent a day or
+two traveling around, making inquiries.
+
+The young inventor and his companion proceeded on foot to a
+small settlement, where they hired horses on which to make their
+way about. They were to be gone two days, and in that time they
+hoped to get on the right trail.
+
+
+
+
+CHAPTER XII--THE GREAT STONE HEAD
+
+
+It was a wild and desolate country in which Tom Swift and Mr.
+Jenks were traveling. Villages were far apart, and they were at
+best but small settlements. In their journeys from place to place
+they met few travelers.
+
+But of these few they made cautious inquiries as to the
+location of Phantom Mountain, or the landmark known as the great
+stone head. Prospectors, miners and hunters, whom they asked,
+shook their heads.
+
+"I've heard of Phantom Mountain," said one grizzled miner, "but
+I couldn't say where it is. Maybe it's only a fish story--the
+place may not even exist."
+
+"Oh, it does, for I've been there!" exclaimed Mr. Jenks.
+
+"Then why don't you go back to it?" asked the miner.
+
+"Because I can't locate it again," was the reply.
+
+"Humph! Mighty queer if you've seen a place once, and can't get
+to it again," and the man looked as if he thought there was
+something strange about Tom and his companion. Mr. Jenks did not
+want to say that he had been taken to the mountain blindfolded,
+for that would have caused too much talk.
+
+"I think if we spent to-night in a place where the miners
+congregate, listened to their talk, and put a few casual
+questions to them, more as if we were only asking out of idle
+curiosity, we might learn something," suggested Tom.
+
+"Very well, we'll try that scheme."
+
+Accordingly, after they had left the suspicious miner the two
+proceeded to a small milling town, not far from Indian Ridge.
+There they engaged rooms for the night at the only hotel, and,
+after supper they sat around the combined dance hall and gambling
+place.
+
+There were wild, rough scenes, which were distasteful to Tom,
+and to Mr. Jenks, but they felt that this was their only chance
+to get on the right trail, and so they stayed. As strangers in a
+western mining settlement they were made roughly welcome, and in
+response to their inquiries about the country, they were told
+many tales, some of which were evidently gotten up for the
+benefit of the "tenderfeet."
+
+"Is there a place around here called Phantom Mountain?" asked
+Tom, at length, as quietly as he could.
+
+"Never heard of it, stranger," replied a miner who had done
+most of the talking. "I never heard of it, and what Bill
+Slatterly don't know ain't worth knowin'. I'm Bill Slatterly," he
+added, lest there be some doubt on that score.
+
+"Isn't there some sort of a landmark around here shaped like a
+great stone head?" went on Tom, after some unimportant questions.
+"Seems to me I've heard of that."
+
+"Nary a one," answered Mr. Slatterly. "No stone heads, and no
+Phantom Mountains--nary a one.
+
+"Who says there ain't no Phantom Mountains?" demanded an
+elderly miner, who had been dozing in one corner of the room, but
+who was awakened by Slatterly's loud voice. "Who says so?"
+
+"I do," answered the one who claimed to know everything.
+
+"Then you're wrong!" Tom's heart commenced beating faster than
+usual.
+
+"Do you mean to say you've seen Phantom Mountain, Jed Nugg?"
+demanded Slatterly.
+
+"No, I ain't exactly seen it, an' I don't want to, but there is
+such a place, about sixty mile from here. Folks says it's
+haunted, and them sort of places I steer clear from."
+
+"Can you tell me about it?" asked Mr. Jenks, eagerly. "I am
+interested in such things."
+
+"I can't tell you much about it," was the reply, "and I
+wouldn't git too interested, if I was you. It might not be
+healthy. All I know is that one time my partner and I were in
+hard luck. We got grub-staked, and went out prospectin'. We
+strayed into a wild part of the country about sixty mile from
+here, and one night we camped on a mountain--a wild, desolate
+place it was too."
+
+The miner stopped, and began leisurely filling his pipe.
+
+"Well?" asked Tom, trying not to let his voice sound too eager.
+
+"Well, that was Phantom Mountain."
+
+The miner seemed to have finished his story.
+
+"Is that all?" asked Mr. Jenks. "How did you know it was
+Phantom Mountain?"
+
+"'Cause we seen the ghost--my partner and I--that's why!"
+exclaimed the man, puffing on his pipe. "As I said, we was
+campin' there, and 'long about midnight we seen somethin' tall
+and white, and all shimmerin', with a sort of yellow fire,
+slidin' down the side of the mountain It made straight for our
+camp."
+
+"Huh! Guess you run, didn't you, Jed?" asked Bill Slatterly.
+
+"Course we did. You'd a run too, if you seen a ghost comm' at
+you, an' firm' a gun."
+
+"Ghosts can't fire guns!" declared Bill. "I guess you dreamed
+it, Jed."
+
+"Ghosts can't fire guns, eh? That's all you know about it. This
+one did, and to prove I didn't dream it, there was a bullet hole
+in my hat next mornin'. I could prove it, too, only I ain't got
+that hat any more. But that was Phantom Mountain, strangers, an'
+my advice to you is to keep away from it. I was on it but I
+didn't exactly see it, 'cause it was dark at the time."
+
+"Was it near a peak that looked like a stone
+head?" asked Tom.
+
+"It were, stranger, but I didn't take much notice of it. Me and
+my partner got out of them diggin's next day, and I never went
+back. I ain't never said much about this place, but it's called
+Phantom Mountain all right, and I ain't the only one that's seen
+a ghost there. Other grub-stakers has had the same experience."
+
+"Why ain't I never heard about it?" demanded Bill,
+suspiciously.
+
+"'Cause as why you're allers so busy talkin' that you don't
+never listen to nothin' I reckon," was Jed's answer, amid
+laughter.
+
+"Can you tell us what trail to take to get there?" asked Tom,
+of the miner.
+
+"Yes, it's called the old silver trail, and you strike it by
+goin' to a place called Black Gulch, about forty mile from here.
+Then it's twenty mile farther on. But take my advice and don't
+go."
+
+"Can it be reached by way of Indian Ridge?" asked Mr. Jenks,
+wondering how he had been taken to the cave of the diamond
+makers. He did not remember Black Gulch.
+
+"Yes, you can git there by Indian Ridge way, but it's more
+dangerous. You're likely to lose your way, for that's a trail
+that's seldom traveled." Mr. Jenks thought that, perhaps, was the
+reason the gang had taken him that way. "It's easier to get to
+the stone head and Phantom Mountain by Black Gulch, but it ain't
+healthy to go there, strangers, take my advice on that,"
+concluded the miner, as he prepared to go to sleep again.
+
+Tom could scarcely contain the exultation he felt. At last, it
+seemed, they were on the trail. He motioned to Mr. Jenks, and
+they slipped quietly from the place, just as another dance was
+beginning.
+
+"Now for Black Gulch!" cried Tom. "We must hurry back to the
+airship, and tell the good news.
+
+"It's too late to-night," decided Mr. Jenks, and so they waited
+until morning, when they made an early start.
+
+They found Mr. Damon and Mr. Parker anxiously awaiting their
+return. Mr. Damon blessed so many things that he was nearly out
+of breath, and Mr. Parker related something of the observations
+he had made.
+
+"I think I have discovered traces of a dormant volcano," he
+said. "I am in hopes that it will have an eruption while we are
+here."
+
+"I'm not," spoke Tom, decidedly. "We'll start for Black Gulch
+as soon as possible."
+
+The airship once more rose in the air, and, following the
+directions the miner had given him, Tom pointed his craft for the
+depression in the mountains which had been given the name Black
+Gulch. It was reached in a short time, and then, making a turn up
+a long valley the airship proceeded at reduced speed.
+
+"We ought to see that stone head soon now," spoke Tom, as he
+peered from the windows of the pilot house.
+
+"It's queer we didn't notice it when we were up in the air,"
+remarked Mr. Jenks. "We've been over this place before, I'm sure
+of it."
+
+The next moment Mr. Damon uttered a cry. "Bless my watch-chain!"
+he exclaimed. "Look at that!"
+
+He pointed off to the left. There, jutting out from the side of
+a steep mountain peak was a mass of stone--black stone--which, as
+the airship slowly approached, took the form and shape of a
+giant's head.
+
+"That's it! That's it!" cried Tom. "The great stone head!"
+
+"And now for Phantom Mountain and the diamonds!" shouted Mr.
+Jenks, as Tom let the airship slowly settle to the bottom of the
+valley.
+
+
+
+
+CHAPTER XIII--ON PHANTOM MOUNTAIN
+
+
+Out from the Red Cloud piled Tom and the others. They made a
+rush for the irregular mass of rock which bore so strong a
+resemblance to the head of some gigantic man.
+
+"That's the one! That's the thing I saw when they were taking
+me along here blindfolded!" exclaimed Mr. Jenks. "I'm sure we're
+on the right trail, now!"
+
+"But what gets me, though," remarked Mr. Damon, "is why we
+couldn't see that landmark when we were up in the air. We had a
+fine view, and ought to have been able to pick it out with the
+telescopes."
+
+The adventurers saw the reason a few seconds later. The image
+was visible only from one place, and that was directly looking up
+the valley. If one went too far to the right or left the head
+disappeared from view behind jutting crags, and it was impossible
+to see it from overhead, because the head was almost under a
+great spur of a mighty mountain.
+
+"We might have hunted for it a week in the airship, and been
+directly over it," said Tom, "and yet we would never have seen
+it."
+
+"Yes, but we never would have gotten here in such good shape if
+it hadn't been for your wonderful craft," declared Mr. Jenks. "It
+brought us here safely and quickly, and enabled us to elude the
+men who tried to keep us back. We're here in spite of them. If we
+had traveled by train they might have interfered with us in a
+dozen ways."
+
+"That's so," agreed Mr. Damon. "Well, now we're here, what's to
+be done? Which way do we start to reach the cave where the
+diamonds are manufactured, Mr. Jenks?"
+
+"That I can't say. As you know, I only had a momentary glimpse
+of this stone head as they wore taking me along the trail. Then
+one the men noticed that the bandage had slipped and he pulled it
+into place. So I really can't say which direction to take now, in
+order to discover the secret."
+
+"How long after you saw the head before you reached the cave?"
+asked Tom. "In that way we may be able to tell how far away it
+is."
+
+"Well, I should say it was about two or three hours after I saw
+the head, before we got to the halting place, and I was carried
+into the cave. That would make it several miles from here, for we
+went in a wagon."
+
+"Yes, and they might have driven in a round-about way, in order
+to deceive you," suggested Mr. Damon. "At best we have but a
+faint idea where the diamond cave is, but we must search for it;
+eh, Tom?"
+
+"Certainly. We'll start right in. And as the airship will be of
+but little service to us now, I suggest that we leave it in this
+valley. It is very much secluded, and no one will harm it, I
+think. We can then start off prospecting, for I have a large
+portable tent, and we can carry enough food with us, with what
+game we can shoot, to enable us to live. I have a regular camping
+outfit on board."
+
+"Fine!" cried Mr. Parker, "and that will give me a chance to
+make some observations among the mountains, and perhaps I can
+predict when a landslide, or an eruption of some dormant volcano,
+may occur."
+
+"Bless my stars!" cried Mr. Damon. "I don't wish you any bad
+luck, Mr. Parker, but I sincerely hope nothing of the sort
+happens! We had enough of that on Earthquake Island!"
+
+"One can not halt the forces of nature," said the scientist,
+solemnly. "There are many towering peaks around here which may
+contain old volcanoes. And I notice the presence of iron ore all
+about. This must be a wonderful place in a thunder and lightning
+storm."
+
+"Why?" asked Tom, curiously.
+
+"Because lightning would be powerfully attracted here by the
+presence of the metal. In fact there is evidence that many of the
+peaks have been struck by lightning," and the scientist showed
+curious, livid scars on the stone faces of the peaks within
+sight.
+
+"Then this is a good place to stay away from in a storm,"
+observed Mr. Damon. "However, we won't worry about that now. If
+this is the landmark Mr. Jenks was searching for, then we must be
+in the vicinity of Phantom Mountain."
+
+"I think we are," declared the diamond seeker. "Probably it is
+within sight now, but there are so many peaks, and this is such a
+wild and desolate part of the country that we may have trouble in
+locating it."
+
+"We've got to make a beginning, anyhow," decided Tom, "and the
+sooner the better. Come, we'll make up our camping kits, and
+start out."
+
+It was something to know that they were on the right trail, and
+it was a relief to be able to busy oneself, and not be aimlessly
+searching for a mysterious landmark. They all felt this, and soon
+the airship was taken to a secluded part of the valley, where it
+was well hidden from sight in a grove of trees.
+
+Tom and Mr. Damon then served a good meal, and preparations
+were made to start on their search among the mountains--a search
+which they hoped would lead them to Phantom Mountain, and the
+cave of the diamond makers.
+
+The tent which would afford them shelter was in sections, and
+could be laced together. They carried food, compressed into small
+packages, coffee, a few cooking utensils; and each one had a gun,
+Tom carrying a combination rifle and shotgun, for game.
+
+"We can't live very high while we're on the trail," said the
+young inventor, "but it won't be much worse than it was on
+Earthquake Island. Are we all ready?"
+
+"I guess so," answered Mr. Damon. "How long are we going to be
+away?"
+
+"Until we find the diamond makers!" declared Tom, firmly.
+
+Shouldering their packs, the adventurers started off. Tom
+turned for a last look at his airship, dimly seen amid the trees.
+Would he ever come back to the Red Cloud? Would she be there when
+he did return? Would their quest be successful? These questions
+the lad asked himself, as he followed his companions along the
+rocky trail.
+
+"Perhaps we can find the road by which these men go in and out
+of the cave," suggested Mr. Damon, when they had gone on for
+several miles.
+
+"I fancy not," replied Mr. Jenks. "They probably take great
+pains to hide it. I think though, that our best plan will be to
+go here and there, looking for the entrance to the cave. I
+believe I would remember the place."
+
+"But why can't you follow the directions given by the miner who
+told you about Phantom Mountain?" asked Mr. Damon.
+
+"Because his talk was too indefinite," answered Mr. Jenks. "He
+was so frightened by seeing what he believed to be a ghost, that
+he didn't take much notice of the location of the place. All he
+knows is that Phantom Mountain is somewhere around here."
+
+"And we've got to hunt until we find it; is that the idea?"
+asked Mr. Parker.
+
+"Or until we see the phantom" added Tom, in a low voice.
+
+"Bless my topknot!" exclaimed Mr. Damon. "You don't mean to say
+you expect to see that ghost; do you Tom?"
+
+"Perhaps," answered the young inventor, and he did not add
+something else of which he was thinking. For Tom had a curious
+theory regarding the phantom.
+
+They tramped about the remainder of that day. Toward evening
+Tom shot some birds, which made a welcome addition to their
+supper. Then the tent was put together, some spruce and hemlock
+boughs were cut to make a soft bed, and on these, while the light
+of a campfire gleamed in on them, the adventurers slept.
+
+Their experience the following day was similar to the first.
+They saw no evidence of a large cave such as Mr. Jenks had
+described, nor were there any traces of men having gone back and
+forth among the mountains, as might have been expected of the
+diamond makers, for, as Mr. Jenks had said, they made frequent
+journeys to the settlement for food, and other supplies.
+
+"Well, I haven't begun to give up yet," announced Tom, on the
+third day, when their quest was still unsuccessful. "But I think
+we are making one mistake."
+
+"What is that?" inquired Mr. Jenks.
+
+"I think we should go up higher. In my opinion the cave is near
+the top of some peak; isn't it, Mr. Jenks?"
+
+"I have that impression, though, as you know, I never saw the
+outside of it. Still, it might not be a bad idea to ascend some
+of these peaks."
+
+Following this suggestion, they laid their trail more toward
+the sky, and that night found them encamped several thousand feet
+above the sea-level. It was quite cool, and the campfire was a
+big one about which they sat after supper, talking of many
+things.
+
+Tom did not sleep well that night. He tossed from side to side
+on the bed of boughs, and once or twice got up to replenish the
+fire, which had burned low. His companions were in deep slumber.
+
+"I wonder what time it is?" mused Tom, when he had been up the
+third time to throw wood on the blaze. "Must be near morning." He
+looked at his watch, and was somewhat startled to see that it was
+only a little after twelve. Somehow it seemed much later.
+
+As he was putting the timepiece back into his pocket the lad
+looked around at the dark and gloomy mountains, amid which they
+were encamped. As his gaze wandered toward the peak of the one on
+the side of which the tent was pitched, he gave a start of
+surprise.
+
+For, coming down a place where, that afternoon, Tom had noticed
+a sort of indefinite trail was a figure in white. A tall, waving
+figure, which swayed this way and that--a figure which halted and
+then came on again.
+
+"I wonder--I wonder if that can be a wisp of fog?" mused the
+young inventor. He rubbed his eyes, thinking it might be a
+swirling of the night mist or a defect of vision. Then, as he saw
+more plainly, he noticed the thing in white rushing toward him.
+
+"It's the phantom--the phantom!" cried Tom, aloud. "It's the
+thing the miner saw! We're on Phantom Mountain now!"
+
+
+
+
+CHAPTER XIV--WARNED BACK
+
+
+Tom's cries awakened the sleepers in the tent. Mr. Damon was
+the first to rush out.
+
+"Bless my nightcap, Tom!" he cried. "What is it? What has
+happened? Are we attacked by a mountain lion?"
+
+For answer the young inventor pointed up the mountain, to
+where, in the dim light from a crescent moon, there stood boldly
+revealed, the figure in white.
+
+"Bless--bless my very existence!" cried the odd man. "What is
+it, Tom?"
+
+"The phantom," was the quiet answer. "Watch it, and see what it
+does."
+
+By this time Mr. Jenks and Mr. Parker had joined Tom and Mr.
+Damon. The four diamond seekers stood gazing at the apparition.
+And, as they looked, the thing in white, seemingly too tall for
+any human being, slid slowly forward, with a gliding motion. Then
+it raised its long, white arms, and waved them threateningly at
+the adventurers.
+
+"It's motioning us to go back," said Mr. Parker in an awed
+whisper. "It doesn't want us to go any farther."
+
+"Very likely," agreed Tom, coolly. "But we're not going to be
+frightened by anything like that; are we?"
+
+"Not much!" exclaimed Mr. Jenks. "I expected this. A ghost
+can't drive me back from getting my rights from those scoundrels!"
+
+"Suppose it uses a revolver to back up its demand?" asked the
+scientist.
+
+"Wait until it does," answered Mr. Jenks. But the figure in
+white evidently had no such intentions. It came on a little
+distance farther, still waving the long arms threateningly, and
+then it suddenly disappeared, seeming to dissolve in the misty
+shadows of the night.
+
+"Bless my suspenders!" cried Mr. Damon. "That's a very
+strange proceeding! Very strange! What do you make of it, Tom?"
+
+"It is evidently some man dressed up in a sheet," declared Mr.
+Jenks. "I expected as much."
+
+"The work of those diamond makers; do you think?" continued Mr.
+Damon.
+
+"I believe so," answered Tom, slowly, for he was trying to
+think it out. "I believe they are the cause of the phantom,
+though I don't know that it's a man dressed in a sheet."
+
+"Why isn't it?" demanded Mr. Jenks.
+
+"Because it was too tall for a man, unless he's a giant."
+
+"He may have been on stilts," suggested Mr. Parker.
+
+"No man on stilts could walk along that way," declared Tom,
+confidently. "He glided along too easily. I am inclined to think
+it may be some sort of a light."
+
+"A light?" queried Mr. Damon.
+
+"Yes, the diamond makers may be hidden in some small cave near
+here, and they may have some sort of a magic lantern or a similar
+arrangement, for throwing a shadow picture. They could arrange it
+to move as they liked, and could cause it to disappear at will.
+That, I think, is the ghost we have just seen."
+
+"But the diamond makers have only been in this mountain
+recently," objected Mr. Jenks, "and the phantom was here before
+them. In fact, that was what gave the place its name."
+
+"That may be," admitted the lad. "There are many places that
+have the name of being haunted, but no one ever sees the ghost.
+It is always some one else, who has heard of some one who has
+seen it. That may have been the case here. I grant that this
+place may have been called 'Phantom Mountain' for a number of
+years, due to the superstitious tales of miners. The diamond
+makers came along, found the conditions just right for their
+work, and adopted the ghost, so to speak. As there wasn't any
+real spirit they made one, and they use it to scare people away.
+I think that's what we've just seen, though I may be wrong in my
+theory as to what the phantom is."
+
+"Well, it's gone now, at any rate," said Mr. Jenks, "and I
+think we'd better get back inside the tent. It's cold out here."
+
+"Aren't some of us going to stand guard?" demanded Mr. Damon.
+
+"What for?" asked Mr. Jenks.
+
+"Why--er--bless my key-ring! Suppose that ghost takes a notion
+to come down here, and use his gun, as he did on the miners?"
+
+"I don't believe that will happen," remarked Tom. "The diamond
+makers, if the white thing had anything to do with them, have
+given us a warning, and I think they'll at least wait until
+morning to see how we heed it."
+
+"We aren't going to heed it!" burst out Mr. Jenks. "I'm going
+to go right ahead and find that cave where they make diamonds!"
+
+"And we're with you!" exclaimed Tom. "We'll have a good fire
+going the rest of the night, and that may keep intruders away. In
+the morning we'll begin our search, and we'll go up the trail
+where we saw the white figure."
+
+A big pile of wood had been collected for the fire, and Tom now
+piled some logs and branches on the blaze. It would last for some
+time now, and the adventurers, still talking of the "ghost" went
+back into the tent. It was over an hour before they all got to
+sleep again, and Mr. Jenks and Mr. Damon took turns in getting up
+once or twice during the remainder of the night to replenish the
+fire.
+
+Morning dawned without anything further having occurred to
+disturb them, and, after a hearty breakfast, to which Tom added
+some fish he caught in a nearby mountain stream, they set off up
+the trail on Phantom Mountain.
+
+They had left their tent standing, as they proposed making that
+spot their headquarters until they located the cave they were
+seeking. What their course would be after that would depend on
+the circumstances.
+
+If they had expected to have an easy task locating the cavern
+in which Mr. Jenks had seen diamonds made, the adventurers were
+disappointed. All that day they tramped up and down the mountain,
+looking for some secret entrance, but none was disclosed. The
+higher they went up the great peak, the fainter became the trail,
+until, at length it vanished completely.
+
+But this was not to be wondered at, since it was on solid rock,
+in which no footsteps would leave an impression.
+
+"They never brought you up here in a wagon, Mr. Jenks," decided
+Tom, when he saw how steep the place was.
+
+"I'm inclined to think so myself," admitted the diamond man.
+"They must have reached the cave from some other way. As a matter
+of fact, I walked some distance after getting out of the vehicle,
+before we got to the cavern. But, even at that, I don't believe
+we came this way."
+
+"Yet the phantom was here," persisted Tom, "and I'm convinced
+that the cave is in this neighborhood. It's up to us to find it!"
+
+But they searched the remainder of that day in vain, and as
+night was coming on, they made their way back to the camp. As
+Tom, who was in the lead, approached the tent, he saw something
+black fastened to the entrance.
+
+"Hello!" he cried. "Some one's been here. That wasn't on the
+tent when he left this morning."
+
+"What is it?" asked Mr. Damon.
+
+"A black piece of paper, written on with white ink," replied
+the lad. He was reading it, and, as he perused it a look of
+surprise came over his face.
+
+"Listen to this!" called Tom. "It's evidently from the diamond
+makers."
+
+Holding up the black paper, on which the white writing stood
+out in bold relief Tom read aloud:
+
+
+"Be warned in time! Go back before it is too late! You are near
+to death! Go back!"
+
+
+"Bless my shoelaces!" cried Mr. Damon. "This is getting
+serious."
+
+
+
+
+CHAPTER XV--THE LANDSLIDE
+
+
+Gathered about the young inventor, the three men looked at the
+warning. The writing was poor, and it was evident that an attempt
+had been made to disguise it. But there was no misspelling of
+words, and there were no rudely drawn daggers, or bloody hands or
+anything of that sort. In fact, it was a very business-like sort
+of warning.
+
+"Rather odd," commented Mr. Jenks. "Black paper and white ink."
+
+"White ink is easy enough to make," stated Mr. Parker. "I fancy
+they wanted it as conspicuous as possible."
+
+"Yes," agreed Tom, "and this warning, together with the antics
+of the thing in white last night, shows that they are aware of
+our presence here, and perhaps know who we are. We will have to
+be on our guard."
+
+"Do you think that fellow Munson, whom we left in the forest,
+could have gotten here and warned them?" asked Mr. Damon.
+
+"It's possible," admitted Tom, "but now let's see if the person
+who pinned this warning on our tent took any of our things."
+
+A hasty examination, however, showed that nothing had been
+disturbed, and Tom and Mr. Damon were soon getting supper ready,
+everyone talking, during the progress of the meal, about the
+events of the day, and the rather weird culmination of it.
+
+"Well, we haven't had a great deal of success--so far,"
+admitted Tom, as they sat about the fire, in the fast gathering
+dusk. "I think, perhaps, we'd better try on the other side of the
+mountain to-morrow. We've explored this side pretty thoroughly."
+
+"Good idea," commented Mr. Jenks. "We'll do it, and move our
+camp. I only hope those fellows don't find our airship and
+destroy it. We'll have a hard time getting back to civilization
+again, if we have to walk all the way."
+
+This contingency caused Tom some uneasiness. He did not like to
+think that the unscrupulous men might damage the Red Cloud, that
+had been built only after hard labor. But he knew he could
+accomplish nothing by worrying, and he tried to dismiss the
+matter from his mind.
+
+They rather expected to see the thing in white again that
+night, but it did not appear, and morning came without anything
+having disturbed their heavy sleep, for they were tired from the
+day's tramp.
+
+It took them the greater part of the day to make a circuit of
+the base of Phantom Mountain in order to get to a place where a
+sort of trail led upward.
+
+"It's too late to do anything to-night," decided Tom, as they
+set up the tent. "We'll rest, and start the first thing in the
+morning."
+
+"And the ghost isn't likely to find us here," added Mr. Damon.
+"Where are you going, Mr. Parker?" he asked, as he saw the
+scientist tramping a little way up the side of the mountain.
+
+"I am going to make some observations," was the answer, and no
+one paid any more attention to him for some time. Supper was
+nearly ready when Mr. Parker returned. His face wore a rather
+serious air, and Mr. Damon, noting it, asked laughingly:
+
+"Well, did you discover any volcanoes, that may erupt during
+the night, and scare us to death?"
+
+"No," replied Mr. Parker, calmly, "but there is every
+indication that we will soon have a terrific electrical storm.
+From a high peak I caught a glimpse of one working this way
+across the mountains."
+
+"Then we'd better fasten the tent well down," called Tom. "We
+don't want it to blow away."
+
+"There will not be much danger from wind," was Mr. Parker's
+opinion.
+
+"From what then?" asked Mr. Jenks.
+
+"From the discharges of lightning among these mountain peaks,
+which contain so much iron ore. We will be in grave danger."
+
+The fact that the scientist had not always made correct
+predictions was not now considered by his hearers, and Tom and
+the two men gazed at Mr. Parker in some alarm.
+
+"Is there anything we can do to avoid it?" asked Mr. Jenks.
+
+"The only thing to do would be to leave the mountain," was the
+answer, "and, as the iron ore extends for miles, we can not get
+out of the danger zone before the storm will reach us. It will be
+here in less than half an hour."
+
+"Then we'd better have supper," remarked Tom, practically, "and
+get ready for it. Perhaps it may not be as bad as Mr. Parker
+fears."
+
+"It will be bad enough," declared the gloomy scientist, and he
+seemed to find pleasure in his announcement.
+
+The meal was soon over, and Tom busied himself in looking to
+the guy ropes of the tent, for he feared lest there might be wind
+with the storm. That it was coming was evident, for now low
+mutterings of thunder could be heard off toward the west.
+
+Black clouds rapidly obscured the heavens, and the sound of
+thunder increased. Fitful flashes of lightning could be seen
+forking across the sky in jagged chains of purple light.
+
+"It's going to be a heavy storm," Tom admitted to himself. "I
+hope lightning doesn't strike around here."
+
+The storm came on rapidly, but there was a curious quietness in
+the air that was more alarming than if a wind had blown. The
+campfire burned steadily, and there was a certain oppressiveness
+in the atmosphere.
+
+It was now quite dark, save when the fitful lightning flashes
+came, and they illuminated the scene brilliantly for a few
+seconds. Then, by contrast, it was blacker than ever.
+
+Suddenly, as Tom was gazing up toward the peak of Phantom
+Mountain, he saw something that caused him to cry out in alarm.
+He pointed upward, and whispered hoarsely:
+
+"The ghost again! There's our friend in white!"
+
+The others looked, and saw the same weird figure that had
+menaced them when they were encamped on the other side of the
+peak.
+
+"They must have followed us," said Mr. Jenks, in a low voice.
+
+Slowly the figure advanced, It waved the long white arms, as if
+in warning. At times it would be only dimly visible in the
+blackness, then, suddenly it would stand out in bold relief as a
+great flash of fire split the clouds.
+
+The thunder, meanwhile, had been growing louder and sharper,
+indicating the nearer approach of the storm. Each lightning flash
+was followed in a second or two, by a terrific clap. Still there
+was no wind nor rain, and the campfire burned steadily.
+
+All at once there was a crash as if the very mountain had split
+asunder, and the adventurers saw a great ball of purple-bluish
+fire shoot down, as if from some cloud, and strike against the
+side of the crag, not a hundred feet from where stood the ghostly
+figure in white.
+
+"That was a bad one," cried Mr. Damon, shouting so as to be
+heard above the echoes of the thunderclap.
+
+Almost as he spoke there came another explosion, even louder
+than the one preceding. A great ball of fire, pear shaped, leaped
+for the same spot in the mountain.
+
+"There's a mass of iron ore there!" yelled Mr. Parker. "The
+lightning is attracted to it!"
+
+His voice was swallowed up in the terrific crash that followed,
+and, as there came another flash of the celestial fire, the
+figure in white could be seen hurrying back up the mountain
+trail. Evidently the electrical storm, with lightning bolts
+discharging so close, was too much for the "ghost."
+
+In another instant it looked as if the whole place about where
+the diamond seekers stood, was a mass of fire. Great forked
+tongues of lightning leaped from the clouds, and seemed to lick
+the ground. There was a rattle and bang of thunder, like the
+firing of a battery of guns. Tom and the others felt themselves
+tingling all over, as if they had hold of an electrical battery,
+and there was a strong smell of sulphur in the air.
+
+"We are in the midst of the storm!" cried Mr. Parker. "We are
+standing on a mass of iron ore! Any minute may be our last!"
+
+But fate had not intended the adventurers for death by
+lightning. Almost as suddenly as it had begun, the discharge of
+the tongues of fire ceased in the immediate vicinity of our
+friends. They stood still--awed--not knowing what to do.
+
+Then, once more, came a terrific clap! A great mass of fire,
+like some red-hot ingot from a foundry, was hurled through the
+air, straight at the face of the mountain, and at the spot where
+the figure in white had stood but a few minutes before.
+
+Instantly the earth trembled, as it had at Earthquake Island,
+but it was not the same. It was over in a few seconds. Then, as
+the diamond seekers looked, they saw in the glare of a score of
+lightning flashes that followed the one great clap, the whole
+side of the mountain slip away, and go crashing into the valley
+below.
+
+"A landslide!" cried Mr. Parker. "That is the landslide which I
+predicted! The lightning bolt has split Phantom Mountain!"
+
+
+
+
+CHAPTER XVI--THE VAST CAVERN
+
+
+For a time the roiling, slipping, sliding and tumbling of the
+mass of earth and stones, down the side of the mountain,
+effectually drowned all other sounds. Even the thunder was
+stilled, and though Tom and his companions called to one another
+in terror, their voices could not rise above that terrific
+tumult.
+
+Finally, when they found that the direction of the slide was
+away from their tent, and that they were not likely to be
+engulfed, they grew more calm.
+
+Gradually the noise subsided. The great boulders had rolled to
+the bottom of the valley, and now only a mass of earth and stones
+was sliding down. Even this stopped in about five minutes, and,
+as though satisfied with what it had done, the electrical storm
+passed. Not a drop of rain had fallen.
+
+"Bless my shirt studs!" exclaimed Mr. Damon, who was the first
+to speak after the din had quieted. "Bless my soul! But that was
+awful!"
+
+"It was just what I expected," said Mr. Parker, calmly. "I
+knew, from my observations, that we were in a region where
+landslides and terrific electrical storms may be expected at any
+time. I fully looked for this."
+
+"Well," remarked Mr. Jenks, rather sarcastically, "I hope it
+came up to your expectations, Mr. Parker."
+
+"Oh, fully," was the answer, "though I wish it could have
+happened in daylight, so that I could better have observed
+certain phenomena regarding the landslide. They are very
+interesting."
+
+"At a distance," admitted Tom, with a laugh of relief. "Well,
+I'm glad it's over, though we'll have to wait until morning to
+see what damage has been done. Lucky we weren't struck by
+lightning. I never saw such bolts!"
+
+"Me, either!" declared Mr. Damon. "This mountain seems to
+attract them."
+
+"It is like a magnet," said Mr. Parker. "I think I shall be
+able to make some fine observations here."
+
+"If we live through it," murmured Mr. Jenks.
+
+They watched the play of lightning about a distant bank of
+clouds, but the storm was now far away, only a faint rumbling of
+thunder being heard.
+
+"I'm wondering what happened to the phantom," said Tom, after a
+pause. "Seems to me he was right in that track of the storm."
+
+"Do you think it was a 'he'?" asked Mr. Jenks.
+
+"I think we'll find that it's some sort of a man," answered the
+young inventor. "We may find out very soon, now. I've changed my
+theory about the ghost being reflections of light."
+
+"How's that?" Mr. Damon wanted to know.
+
+"Well, I think we are on the side of Phantom Mountain where the
+diamond cave is," went on the lad. "The fact that the phantom
+appeared here, soon after we arrived, shows that the men kept
+close track of our movements. It also shows, I think, that the
+phantom did not have to travel far to be on the spot, whereas we
+had to make quite a trip to get around the base of the mountain.
+I think the cave is up there," and Tom pointed toward the spot
+where the weird figure had been last seen, before the storm drove
+it back.
+
+"There may be two phantoms," suggested Mr. Jenks. "They may
+keep one on this side of the mountain, and one on the other, to
+warn intruders away.
+
+"It's possible," admitted Tom. "Well, we'll see how things look
+in the morning, when we'll take up our march again, and go up the
+mountain. We'll reach the top, if possible, which we couldn't do
+from the other side, as it was too steep."
+
+"I hope we shall be able to go forward in the morning," came
+from Mr. Jenks.
+
+"What do you mean?" asked the lad, struck by a peculiar
+significance in the diamond man's tones.
+
+"Why, that landslide may have opened a great gully in the side
+of Phantom Mountain, which will prevent us from passing. It was a
+terrific lot of earth and stones that slid away," answered Mr.
+Jenks.
+
+"It certainly was," agreed Mr. Parker. "I would not be
+surprised if the mountain was half destroyed, and it may be that
+the diamond cave no longer exists."
+
+"Not very cheerful, to say the least," murmured Mr. Jenks to
+Tom, and, as it was getting quite chilly, following the storm,
+they went inside the tent.
+
+Tom could hardly wait for daylight, to get up and see what
+havoc the landslide had wrought. As soon as the first faint flush
+of dawn showed over the eastern peaks, he hurried from the tent.
+Mr. Damon heard him arise, and followed.
+
+A curious scene met their eyes. All about were great rocks rent
+and torn by the awful power of the lightning. The fronts of the
+stone cliffs were scarred and burned by the electrical fire, and
+fantastic markings, grotesque faces, and leering animals seemed
+to have been drawn by some gigantic artist who used a bolt from
+heaven for his brush.
+
+But the eyes of Tom and Mr. Damon took all this in at a glance,
+and then their gaze went forward to where the avalanche had torn
+away a great part of the mountain.
+
+"Whew! I should say it was a landslide!" cried Tom.
+
+"Bless my wishbone, yes!" agreed Mr. Damon.
+
+Below them, in the valley, lay piled immense masses of earth
+and stones. Boulders were heaped up on boulders, and rocks upon
+rocks, being tossed about in heaps, strung about in long ridges,
+and swirled about in curves, as though some cyclone had toyed
+with them after the lightning flash had tossed them there.
+
+"But the mountain isn't half gone," said Tom, as his eyes took
+in what was left of the phantom berg. "I guess it will take a few
+more bolts like that one, to put this hill out of business."
+
+Though the landslide had been a great one, the larger part of
+the mountain still stood. An immense slice had been taken from
+one side, but the summit was untouched.
+
+"And there's where the diamond cave is!" cried Tom, pointing to
+it.
+
+"I think so myself," agreed Mr. Jenks, who came from the tent
+at that moment, and joined the lad and Mr. Damon. "I think we
+shall find the cave somewhere up there. We must start for it, as
+soon as we have eaten, and we may reach it by night."
+
+The three stood gazing up toward the summit of the great
+mountain. Suddenly, as the sun rose higher in the heavens, it
+sent a shaft of rosy light on the face of the berg that had been
+scarred by the landslide. Tom Swift uttered an exclamation, and
+pointed at something.
+
+"See!" he cried. "Look where the trail is--the trail down which
+the phantom must have come. It is on the edge of a cliff now!"
+
+They looked, and saw that this was so. The increasing light had
+just revealed it to them. When the lightning bolt had torn away a
+great portion of the mountain it had cut sheer down for a great
+depth and when the earth and stones fell away they left a narrow
+pathway, winding around the mountain, but so near the edge of a
+great chasm, that there was room but for one person at a time to
+walk on that footway. The uncertain trail up Phantom Mountain had
+all but been destroyed.
+
+"The way up to the peak is by that path, now," spoke Tom, in a
+low voice.
+
+"Bless my soul!" cried Mr. Damon. "It's as much as a man's life
+is worth to attempt it. If he got dizzy, he'd topple over, and
+fall a thousand feet. Dare we risk it?"
+
+"It's the only way to get up," went on Tom. "It's either that
+way, or not at all. We've tried the other side without success.
+We must go up this way--or turn back."
+
+"Then we'll go up!" cried Mr. Jenks. "It may not be as
+dangerous as it looks from here."
+
+But it was even more dangerous than it appeared, when they went
+part way up it after a hasty breakfast. The trail was a mere
+ledge of rock now, and in some places, to get around a projecting
+edge of the mountain, they had to stand with their backs to the
+dizzy depths at their feet, and with both arms outstretched work
+their way around to where the trail was wider.
+
+"Shall we risk it?" asked Tom, when they had tried the way, and
+found it so dangerous. "We can't take anything with us--even our
+guns, for we couldn't carry them, and if we reach the month of
+the cave, and find those men there--"
+
+He paused significantly. The adventurers looked at one another.
+The search for the diamond makers was becoming more and more
+dangerous.
+
+"I say let's go on!" decided Mr. Damon, suddenly. "We want to
+locate that cave, first of all. Perhaps, when we do find it, we
+may see some easier way of getting to it than this. And if those
+diamond makers do attack us--well, I don't believe they'll shoot
+defenseless men, and they may listen to reason, and give Mr.
+Jenks his rights--tell him how to make diamonds in return for the
+money he gave them."
+
+"I don't believe those scoundrels will listen to reason,"
+replied the diamond man, "but I agree with Mr. Damon that we
+ought to go on. We may find some other means of reaching the
+cave--if we can discover it, and we'll take a chance with the
+men."
+
+"Forward it is, then!" cried Tom. "I have a revolver, and I can
+supply one of you gentlemen with another. They may come in useful
+in an emergency. Let's go back to camp, take a little lunch in
+our pockets, and try to scale the mountain."
+
+They were soon on their way up the dizzy path once more, and,
+as they advanced, they found it growing more and more dangerous.
+In some places they found it almost impossible to get around
+certain corners, where there was barely room for their feet. As
+Tom remarked grimly, a fat man never could have done it.
+Fortunately they were all comparatively thin, for their hard
+work, and not too abundant food, since they had left the airship,
+had reduced their weight.
+
+Up and up they went, higher and higher, sometimes finding the
+path wide enough for two to walk abreast, and again seeing it
+narrow almost to a ribbon. They hardly dared look down into the
+chasm at their left--a chasm filled, in part, with the rocks and
+boulders tossed into it by the lightning bolt.
+
+Tom was in the lead, and had just made a dangerous turn around
+a shoulder of rock--one of those places where he had to extend
+both arms, and fairly hug the cliff before he could get around.
+
+But, when he had made it, and found himself on a broad pathway,
+cut in the living rock, he gave a great shout--a shout that
+caused his companions to hasten to his side. They found the young
+inventor pointing to a clump of bushes and small trees.
+
+But it was not the shrubbery that Tom desired to call to their
+attention. They saw that in an instant, for, dimly seen through
+the leaves, was something black, and, as they looked more
+closely, they saw that it was a great hole in the side of the
+mountain--a vast cavern, opening like a tunnel.
+
+"The cave! The cave!" cried Tom. "The diamond makers' cave!"
+
+Hardly had he spoken than two men, each one carrying a gun,
+showed themselves in the mouth of the cavern, and, instant later
+they both ran toward the little party of adventurers.
+
+
+
+
+CHAPTER XVII--THE PHANTOM CAPTURED
+
+
+Surprise held Tom and his friends almost spellbound for the
+moment. The young inventor's hand went toward the pocket where he
+carried his revolver. Mr. Jenks, who had the only other weapon,
+sought to draw it, but he was stopped by a gesture of one of the
+two men with guns.
+
+"Hold on, strangers!" the man cried. "I know what you're up to!
+Better not try to draw anything--it might not be healthy. Now,
+then, who are you, and what do you want?"
+
+The question came rather as a surprise, at least to Tom and Mr.
+Jenks. They had taken it for granted that these men--if they were
+the diamond makers--would know Mr. Jenks, and guess at his errand
+in coming back to Phantom Mountain. But, it seemed, that they
+took them all for casual strangers.
+
+No one answered for a moment. Tom caught the eye of Mr. Jenks,
+and there was a look of hope in it. If ever there was a time for
+strategy, it was now. Evidently Munson, the stowaway on the
+airship, had not yet been able to send a warning to his
+confederates. And neither of the two men recognized Mr. Jenks as
+the man who had been defrauded of his rights. It might be
+possible to conceal the real object of the adventurers until they
+had time to formulate a plan of action.
+
+"Well," exclaimed the man with the gun, impatiently, "I ask you
+folks a question. What do you want?"
+
+Fortunately, neither Mr. Damon nor Mr. Parker replied. The
+former because he deferred to Tom and Mr. Jenks, and the
+scientist because he was busy inspecting some curious rocks he
+picked up. As it turned out this was the luckiest thing he could
+have done. It lent color to what Mr. Jenks said a moment later.
+
+"What are you doing up here?" demanded the man again. "Don't
+you know this is private property?"
+
+"We--we were just looking around," answered Mr. Jenks, which
+was true enough; as far as it went.
+
+"Prospecting," added Tom.
+
+"After gold?" demanded the second man, suspiciously.
+
+"We'd be glad to find some," retorted the lad. At that moment
+Mr. Parker began breaking off bits of rock with a small
+geologist's hammer which he carried. The men with the guns looked
+at him.
+
+"So you think you'll find gold up here?" asked the one who had
+first spoken.
+
+"Is there any?" inquired Tom, trying to make his voice sound
+eager.
+
+"Nary a bit, strangers," was the answer, and the two men
+laughed heartily. "Now, we don't want to seem harsh," went on the
+man who seemed to be the spokesman, "but you'd better get away
+from here. This is private ground, and dangerous too--how'd you
+ever get up the trail--we heard it was destroyed."
+
+"There is still a narrow path," said Mr. Jenks. "We came up
+that--the lightning and landslide haven't left much of it,
+though."
+
+Mr. Parker looked quickly up from the rocks at which he was
+tapping with his small hammer. "You have terrific lightning up
+here," he said. "I am much interested in it, from a scientific
+standpoint. I predict that some day the entire mountain will be
+destroyed by a blast from the sky."
+
+"I hope it won't be right away," spoke one of the men. "Now I
+guess you folks had better be leaving while there's a path left
+to go down by."
+
+"Might I ask," broke in Mr. Parker, as calmly as though he was
+lecturing to a class of students, "might I ask if you have
+noticed any peculiar effect of the lightning up here on the
+summit of the mountain? Does it fuse and melt rocks, so to
+speak?"
+
+"What's that?" cried the spokesman, with a sudden flash of
+anger. The two men looked at each other.
+
+"I wanted to know, merely for scientific reasons, whether the
+lightning up here ever melted rocks?" repeated Mr. Jenks.
+
+"Well, whether it's for scientific reasons or for any other,
+I'm not going to answer you!" snapped the man. "It's none of your
+affair what the lightning does up here. Now you'd all better
+'vamoose'--clear out!"
+
+"All right--we'll go," said Tom, quickly, at the same time
+motioning to Mr. Jenks to agree with him. The eyes of the young
+inventor were roving about. He saw what looked like a second
+trail, leading down the mountain, from the far side of the cave.
+He was convinced now that there was another way to get to it.
+Possibly they might find it. At any rate nothing more could be
+done now. They must go back, for the cavern was too well guarded
+to attempt to enter it by force--at least just yet.
+
+"Yes, we'll go back," assented Mr. Jenks.
+
+Mr. Parker was tapping away at the rocks. He looked toward the
+black mouth of the big cave. On what corresponded to the roof of
+it, some distance back from the entrance, he saw a slender metal
+rod sticking up into the air.
+
+"May I ask if that's a lightning rod?" he inquired innocently.
+"If it is, I should like to ask about its action in a mountain
+that is so impregnated with iron ore.
+
+"You may ask until you get tired!" cried the spokesman, again
+showing unreasoning anger, "but you'll get no answer from us. Now
+get away from here before we do something desperate. You're on
+private ground and you're not wanted. Clear out while you have
+the chance."
+
+There was no help for it. Slowly our friends turned and began
+to go down the dangerous trail. They were soon out of sight of
+the two men who stood before the cave, with their guns ready, but
+neither Tom nor any of his companions spoke for some time.
+
+When they had rounded one of the most dangerous turns the young
+inventor sat down to rest, an example followed by the others.
+
+"Well," asked Tom, "do you think those are some of the diamond
+makers, Mr. Jenks?"
+
+"I certainly do, though I never saw those two men before. If I
+could once get inside the cave, I could tell whether or not it
+was the one where I was practically held a prisoner. But I'm sure
+it is. I know some of the men used to go off every day with guns,
+and not come back until night. I have no doubt they were on
+guard, just as these two are. And, also, I think I heard them
+speak of a second entrance to the cavern. The one we just saw may
+not be the main one, through which I was taken."
+
+"I believe we are on the right track," ventured Mr. Damon, "but
+we will either have to go up there after dark, which will be
+risky, on account of the narrow trail, or else we will have to
+find some other path."
+
+"The last would be better," spoke Tom.
+
+"That rod of metal sticking up on top of the cave interested
+me," said the scientist. "Did you hear anything of that when you
+were here before, Mr. Jenks?"
+
+"No. Probably that is only a lightning rod, or it may be a
+staff for a signal flag. But what surprises me is that those men
+didn't suspect that we were seeking to discover their secret.
+They took us for ordinary prospectors."
+
+"So much the better," remarked Tom. "We have a chance now of
+getting inside that cave. But we will have to go back to camp,
+and make other plans. And we must hurry, or it will be dark
+before we get there."
+
+They hastened their steps, pausing only briefly to eat some of
+the lunch they had brought along, and to drink from a spring that
+bubbled from the side of the mountain. It was getting dusk when
+they got back to their tent. They found nothing disturbed.
+
+"I wonder if we'll see that phantom again to-night?" ventured
+Tom, as they were sitting about the campfire a little later.
+
+"Probably not," remarked Mr. Jenks. "I don't believe the ghost
+will venture down the dangerous trail after dark, and the gang
+may think that the warning given us by the two men on guard at
+the cave will be sufficient. But if we don't leave here by
+to-morrow I think we will have another visit from the thing in
+white."
+
+It was about an hour after this when Tom was collecting some
+wood in a pile nearer the fire, so as to have it ready to throw
+on, in case there was any alarm in the night, that he happened to
+look up toward the summit of the mountain. A slight noise, as of
+loose stones rolling down, attracted his attention, and, at
+first, he feared lest another landslide was beginning, but a
+moment later he saw what caused it.
+
+There, advancing down the steep and dangerous trail was the
+figure in white--the phantom. Instantly a daring plan came into
+Tom's head. Dropping the wood softly, he moved back out of the
+glare of the fire.
+
+"Mr. Jenks!" he called in a whisper.
+
+The diamond man, who was behind the tent, came toward Tom.
+
+"What is it?" he asked. Then, as he saw the ghostly visitor, he
+added: "Oh--the phantom again! What's it up to?"
+
+"The same thing," replied Tom, "but it won't do it long, if my
+plan succeeds."
+
+"What plan is that, Tom?"
+
+"I'm going to try to capture that--that man--or whatever it is.
+Will you help?"
+
+"Surely!"
+
+"Then let's work around behind it, while Mr. Damon and Mr.
+Parker come up from in front. We'll solve this part of the
+mystery, anyhow, if it's possible!"
+
+The two other men were soon told of the plan. Meanwhile the
+thing in white had advanced slowly, until within a few hundred
+feet of the camp. They could see now that it was no shaft of
+light, but some white body, shaped like a tall, thin man, draped
+in a white garment. The long arms waved to and fro. There was no
+semblance of a head.
+
+"You and Mr. Parker go right toward it, slowly, Mr. Damon,"
+advised Tom. "Mr. Jenks and I will make a circle, and get in
+back. Then, if it's anything alive we'll have it."
+
+The "ghost" continued to advance. Tom and the diamond man stole
+off to one side, their buckskin moccasins making no sound. Mr.
+Damon and the scientist went boldly forward.
+
+This movement appeared to disconcert the spirit. It halted,
+waved the arms with greater vigor than before, and seemed to
+indicate to the adventurers that it was dangerous to advance. But
+Mr. Damon and Mr. Parker kept on. They wanted to give Tom and Mr.
+Jenks time enough to make the circuit.
+
+Suddenly the stillness of the night was broken by a low
+whistle. It was Tom's signal that he and Mr. Jenks were ready.
+
+"Come on! Run!" cried Mr. Damon.
+
+The scientist and the eccentric man leaped forward.
+
+The "ghost" heard the whistle, and heard the spoken words. The
+thing in white hesitated a moment, and then raised one arm. There
+was a flash of lire, and a loud report.
+
+"He's firing in the air!" cried Tom. "Come on, we have him
+now!"
+
+Undaunted by the display of firearms, Mr. Damon and Mr. Parker
+kept on. They could hear Tom and Mr. Jenks running up in back of
+the figure. The latter also heard this, and suddenly turned.
+Caught between the two forces of our friends, the "ghost" was at
+a loss what to do.
+
+The next instant Tom, who had distanced Mr. Jenks, made a
+flying tackle for the figure in white, and caught it around the
+legs. Very substantial legs they were, too, Tom felt--the legs of
+a man.
+
+"Wow!" yelled the "ghost," as he went down in a heap, the
+revolver falling from his hand.
+
+"Come on!" cried Tom. "I have him!"
+
+His friends rushed to his aid. There was a confused mass of
+dark bodies, arms and legs mingled with something tall and thin,
+all in white. Suddenly the moon came from behind a cloud and they
+could see what they had captured--for captured the phantom was.
+
+It proved to be a rather small man, who wore upon his shoulders
+a framework of wood, over which some white cloth was draped. It
+had fallen off him when Tom made that tackle.
+
+"Well," remarked the young inventor, as he sat on the
+struggling man's chest. "I guess we've got you."
+
+"I rather guess you have, stranger," was the cool reply.
+
+
+
+
+CHAPTER XVIII--BILL RENSHAW WILL HELP
+
+
+They were all panting from the exertion of the run up the
+mountain and the contest with the phantom--a phantom no longer--though,
+truth to tell, the struggle was not nearly so fierce as
+Tom had expected. He thought the "ghost" would put up a stiff
+fight.
+
+"Got any ropes to tie him with?" asked Mr. Damon, who was
+helping Tom hold the man down.
+
+"Ropes? You aren't going to tie me up are you, strangers?"
+asked the captive.
+
+"That's what we are!" exclaimed Mr. Jenks. "We've had trouble
+enough in this matter, and if I've got one of the gang, perhaps I
+can get some of the others, and have my rights. So tie him up,
+Tom, and we'll take him to camp.
+
+"Oh, you needn't go to all that trouble, strangers," went on
+the man, calmly. "If one of you will get off my chest, and the
+other gentleman ease up on my stomach a bit, I'll walk wherever
+you want me, and not make any trouble. I haven't got a gun."
+
+"Bless my gloves! But you're a cool one," commented Mr. Damon,
+as he complied with the man's request, and got up from his
+stomach. "But look out for him, Tom. He had a gun, for he fired
+it in the air."
+
+"He hasn't it now," answered the young inventor. "I knocked it
+from his hand when I leaped for him."
+
+"That's what you did," assented the man, as he got up, while
+Tom kept a tight hold of him, as did Mr. Jenks. "What kind of a
+grizzly bear hug do you call that, anyhow, that you gave me?"
+
+"That was a football tackle," explained Tom.
+
+"I allers heard that was a dangerous game!" remarked the former
+phantom simply. "Well, now you've got me, what are you going to
+do with me?"
+
+"Take you where we can have a good look at you," replied Mr.
+Jenks, as he kicked aside the wooden framework, and the sheet
+which had made the "ghost" appear so tall. "So this is how you
+worked it; eh?"
+
+"Yep. That was the 'haunt' stranger. I made it myself, and it
+worked all right until you folks come along. I rather suspicioned
+from the first, when I played the trick over on 'tother side of
+the mountain, that you wouldn't be so easy to fool as most
+prospectors are."
+
+"Oh, so you're the only ghost then?" asked Tom.
+
+"I'm the only one."
+
+By this time they had reached the camp. Tom threw some light
+logs on the fire, which blazed up brightly. As the flames
+illuminated the face of their captive, Mr. Jenks looked at him,
+and cried out:
+
+"Why it's Bill Renshaw!"
+
+"That's me," admitted the man who had played the part of the
+phantom, "and thunder-turtles! if it ain't Mr. Jenks who was once
+in the diamond cave with us. Whatever happened to you? I never
+heard. The others said you got tired and went away."
+
+"They took me away--defrauded me of my rights!" declared Mr.
+Jenks, bitterly. "But I'll get them back! To think of Bill
+Renshaw playing the part of a ghost!"
+
+"They made me do it," went on the man, somewhat dejectedly. "I
+wanted to be at work in the cave, but they wouldn't let me."
+
+"Is this man one of the diamond makers?" asked Tom, in great
+surprise.
+
+"He is--one of the helpers, though I don't believe he knows the
+secret of making the gems," explained Mr. Jenks. "He was one of
+the men in the cave when I was there before, and he and I struck
+up quite a friendship; didn't we, Renshaw?"
+
+"That's what, and there ain't no reason why we can't be friends
+now; that is unless you hold a grudge against me for firing at
+you. But I only shot in the air, to scare you away. Them's my
+instructions. I'm supposed to be on guard, and scare away
+strangers. I'm tired of the work, too, for I don't get my share,
+and those other fellows, in the cave, get all the money from the
+diamonds."
+
+Tom Swift uttered an exclamation. A sudden plan had come to
+him. Quickly he whispered to Mr. Jenks:
+
+"Make a friend of this man if possible. He evidently is
+dissatisfied. Offer him a sum to show us another way into the
+cave, and we may yet discover the secret of the diamond makers."
+
+"I will," declared Mr. Jenks, quietly. Then, turning to
+Renshaw, he added:
+
+"Bill, come over here. I want to have a talk with you. Perhaps
+it will be to our mutual advantage."
+
+He led the former phantom to one side, and for some time
+conversed earnestly with him. Mr. Jenks told the story of how he
+had been deceived by Folwell and the others who were at the head
+of the gang of diamond makers. The rich man related how they had
+taken his money, and, after promising to disclose the secret
+process to him, had broken faith, and had drugged him, afterward
+taking him out of the cave.
+
+"I want only my rights, and that for which I paid," concluded
+Mr. Jenks. "Now, I gather that these men haven't treated you
+altogether fairly, Bill."
+
+"Indeed they haven't. I helped 'em to the best of my ability,
+and all I get out of it is to stay out on this lonely side of the
+mountain, and play ghost. They owe me money, too, and they won't
+pay me, either, though they have lots, for they sold some
+diamonds lately."
+
+"Then they are still making diamonds?" asked Mr. Jenks,
+eagerly. "Have you seen them? Do you know the secret?"
+
+"No, I don't know it, for they won't let me in on it. I'm
+always sent out of the cave just before they make the gems. But I
+know they've made some lately, and have sold 'em. I want my
+share."
+
+"Look here!" exclaimed Mr. Jenks, quickly, wishing to strike
+while the iron was hot. "I'll make you a proposition. Show us how
+to get into that cave, unknown to the diamond makers, and I'll
+pay you twice what they agreed to. Is it a bargain?"
+
+Bill Renshaw considered a moment. Then he thrust out his hand,
+clasped that of Mr. Jenks, and exclaimed:
+
+"It is. I'll take you into the cave by an entrance that's
+seldom used. There are four ways to get in. The one where the two
+men drove you back is the rear one. The front one is on the other
+side of the mountain, but it's so well concealed that you'd never
+find it. But I can take you to one where you can get in, and
+those fellows will never know it. And, what's more, I'll help you
+if it comes to a fight!"
+
+"Good!" exclaimed Mr. Jenks. "I think we'll discover the secret
+of the diamond makers this time," and he went to tell the others
+of the success of his talk. Bill Renshaw had been converted from
+an enemy into a friend, and the former phantom was now ready to
+lead Tom and the others into the secret cave.
+
+"We'll start in the morning," decided Mr. Jenks, who, after
+many disappointments, at last saw success ahead of him.
+
+
+
+
+CHAPTER XIX--IN THE SECRET CAVE
+
+
+Tom Swift was up at break of day, and the others were not far
+behind him.
+
+"Now for the secret cave!" cried the young inventor as he gazed
+up the mountain, in the interior of which the mysterious band of
+men were making the diamonds.
+
+"Have you made any plans, Bill?" asked Mr. Jenks of the former
+phantom, who had cast his lot in with the adventurers. "What will
+be the best course for us to follow?"
+
+"You just leave it to me, Mr. Jenks," was the answer. "I'll get
+you into the cave, and those fellows, who, I believe, are trying
+to do me out of my rights, as they did you out of yours, will
+never know a thing about it."
+
+"Bless my finger-nails!" cried Mr. Damon. "That will be great!"
+We can get in the cave, and watch them make the diamonds at our
+leisure."
+
+"They don't make them every day," explained Renshaw. "It seems
+they have to wait for certain occasions. Mostly they make the
+diamonds when there's a big storm."
+
+"A big storm" asked the scientist with a sudden show of
+interest. "Do you mean one of those electrical storms, such as we
+had the other night?"
+
+"That's it, Mr. Parker, though why they wait until there's a
+storm is more than I can tell."
+
+"Perhaps they know that on such occasions no one will venture
+up the mountain," spoke Mr. Damon.
+
+"No, it isn't that," declared the scientist. "I think I am on
+the track of a great scientific discovery, and I will soon be
+able to make observations that will confirm it."
+
+"Well, I'm going to make an observation right now," said Tom,
+with a laugh. "I'm going to see what there is for breakfast."
+
+"And that reminds me," came from Mr. Jenks, "shall we move our
+camp, Bill, and take the tent with us to the cave?"
+
+"I hardly think so," was the answer. "I think the best plan
+would be to conceal the tent somewhere around here, in case you
+might need it again. You can also store what food you have left."
+
+"But, bless my appetite, we don't want to starve in that
+diamond cave!" objected Mr. Damon.
+
+"I'll see that you don't," declared Bill Renshaw. "I'll take
+you in there, unbeknownst to those fellows, and I'll provide you
+with plenty of food and water. You see the cave is so big that
+there are some parts they never visit."
+
+"And we can stay in one of those parts, and eat?" asked Tom.
+
+"Sure," answered Bill.
+
+"And watch the diamond makers at work?" asked Mr. Jenks.
+
+"That's it," replied the former phantom.
+
+"Then the sooner we get started the better," remarked Mr.
+Damon. Mr. Parker said nothing. He appeared to be thinking
+deeply, and was tapping at some rocks with his little hammer.
+
+The advice of Bill Renshaw was followed, and the tent, and what
+food remained, was concealed in the bushes, with rocks piled over
+to keep away prowling animals. Then they started for the secret
+cave.
+
+The man who played the part of a ghost picked up the framework
+and white cloth that had formed his disguise.
+
+"I'll still have to use this," he explained, "for I don't want
+those fellows to know that I'm helping you. I'll continue to play
+the spirit of the mountain, but there won't be much need of it. I
+don't think any more people will come prospecting out here."
+
+"Have you heard of the arrival of Farley Munson?" asked Tom, as
+he related the facts about the stowaway.
+
+"He hadn't arrived up to a day or so ago," answered Bill. "I
+guess he's still traveling. Farley is one of the heads of the
+gang," he added, "and a dangerous man."
+
+As Bill led the way toward the cave, taking a route that the
+adventurers had never suspected led to it, he explained that the
+cavern was a large one, capable of holding an army.
+
+"But there's only a small part of it used by the diamond
+makers," he added. "They work in a small recess, near the summit
+of the mountain. The little cave, where I'm going to take you,
+opens off from it by a long passage. And, except that you'll be
+pretty much in the dark, you'll be quite comfortable. There are
+tables, chairs, and some bunks in the place. I can get you some
+lights, and plenty of food."
+
+"But, if you are seen taking away food, won't the others
+suspect something?" asked Tom.
+
+"I do pretty much as I please," said Bill. "I go and come when
+I like. All I'm supposed to do is to watch my two sides of the
+mountain, play the ghost, and give warning when any one is
+coming. Sometimes I leave black and white messages, like the one
+I put on your tent. Those fellows fix 'em up for me. I've told
+'em about you, though I didn't know who you were, and they think
+you have gone, for the two men on guard at the rear entrance so
+reported. Sometimes I stay out on the mountain for a couple of
+days at a time, when the weather's good, and don't go back to the
+cave. Those times I take food with me, and so if they see me
+making off with some supplies they'll think I'm going to camp
+out."
+
+"It doesn't look as though we'd ever get into a cave near the
+top of the mountain, going this way," said Tom, as they marched
+along. "We're going down, instead of up."
+
+"That's the secret of this trail," explained Bill. "We go down
+in a sort of valley, and then go up a pretty stiff place, and
+then we're on a direct trail to the entrance I told you about.
+It's a steep road to climb, but I guess we can manage it."
+
+And a hard climb the adventurers did find it. The road was
+almost as bad as the one along the edge of the chasm, but they
+managed to negotiate it, and finally found themselves on a fairly
+good trail.
+
+"We'll soon be there," Bill assured them. "After you get in the
+little cave, where I'm going to hide you, I'll have to leave you
+for a spell, until I get my ghost rigging fixed up again. But
+I'll see that you have plenty of food and drink."
+
+A little later their guide came to a sudden halt, and peered
+around anxiously.
+
+"What's the matter?" asked Tom.
+
+"I was just looking to see if any of the men were about," he
+answered. "But I guess not--it looks all right. The entrance is
+right here."
+
+They were on a side of the mountain, near the summit. Below
+stretched a magnificent scene. A great valley lay at their feet,
+and they could look off to many distant peaks. The main trail to
+Leadville, and the one to the settlement of Indian Ridge, was in
+sight.
+
+Suddenly Tom, who had been using a small but powerful
+telescope, uttered an exclamation, and focussed the instrument on
+a speck that seemed moving along on the trail below.
+
+"A man--coming up the mountain," cried Tom. "And--it can't be--yet
+it is--it's Farley Munson--the stowaway!" he cried. "He's coming here!"
+
+"Let me look!" begged Mr. Jenks, taking the glass from Tom. An
+instant later the diamond man exclaimed: "Yes, it's Munson!"
+
+"Then in here with you--quick!" cried Renshaw. "He can't see us
+yet, and we'll be out of sight in another minute."
+
+The former spirit pulled aside some thick bushes, and pointed
+to a hole which was disclosed.
+
+"The entrance to the secret cave," he announced. "Slip in all
+of you."
+
+Tom, after another glance at the man toiling his way up the
+mountain, entered the cavern. He was followed by the others. Bill
+was the last to enter, and he replaced the bushes over the
+entrance.
+
+"At last!" exclaimed Mr. Jenks, as he gazed up at the roof of
+the dimly-lighted vault in which they found themselves.
+
+"Yes, we're in the diamond makers' secret cave," added Tom.
+"Now to catch them at work!"
+
+"Come on," advised Bill, in a low tone, "We're not safe yet,"
+and he produced a lantern from some hidden recess, lighted the
+wick, and led the way. As the others followed they were aware of
+a subdued noise in the great cavern.
+
+
+
+
+CHAPTER XX--MAKING THE DIAMONDS
+
+
+"What's that noise?" asked Tom, as their guide flashed the
+lantern to show them the way.
+
+"That's the men getting ready to make diamonds, I guess," was
+the answer. "You see it takes quite a while to get the stuff
+ready. I don't know what they use--they never tell me any of
+their secrets."
+
+"Oh, I know the ingredients well enough," said Mr. Jenks, "but
+I don't know the secret of how they apply the terrific heat and
+pressure necessary to fuse the materials into diamonds."
+
+"Well, you'll soon know," declared Bill Renshaw. "Of course it
+isn't always successful. I've known 'em to try half a dozen times
+before they got any diamonds big enough to satisfy 'em. They gave
+me some of the small ones when I asked for my wages.
+
+"How did you come to get in with these men?" asked Tom, curious
+to understand how a person seemingly as honest as Renshaw
+appeared to be had cast his lot in with the men who had broken
+faith with Mr. Jenks.
+
+"Oh, I've lived around these parts all my life," was the
+answer. "I knew of this cave before these diamond fellers came to
+it. In fact, I showed it to 'em. It was several years ago that a
+party of men who were prospecting around here came to me and
+asked if I knew of a small cave near the top of a high mountain,
+where lightning storms were frequent. I told them about Phantom
+Mountain, as it was called then, and also of this cave. If
+there's any place where they have worse lightning storms than
+here, I'd like to know it. They scare me, sometimes, like the
+night when that landslide happened, and I'm sort of used to 'em.
+
+"Well, I took these men to the cave, and they hired me as a
+sort of lookout. Then they began their work, and at first I
+didn't know what they were up to, but finally I caught on. Then
+Mr. Jenks came, and disappeared mysteriously, though then I
+didn't know that they had played a trick on him. I was outside
+most of the time, pretending I was the ghost. So that's how I
+came to get in with 'em, and I wish I was out."
+
+"You soon will be, I think," declared Mr. Jenks. "But won't our
+talking be heard by the men?"
+
+"No danger. There is a thick wall between this part of the
+cave, and the part where they live and work. I'll soon have you
+well hid, and then you wait until I come back."
+
+"What about Munson?" asked Tom. "He is evidently on his way
+here to tell his confederates about us."
+
+"He won't know what has happened to us," said Mr. Jenks, "and
+he won't see anything of us. I guess we're safe enough."
+
+Through the dark passage they followed Bill Renshaw until he
+came to a halt in a place that suddenly widened and broadened
+into a good-sized cave.
+
+"Here's your stopping place," said the former ghost. "Now if
+you follow that passage, off to the left," and he pointed to it,
+"you'll come to the larger part of the cave where the diamond
+makers are. But go cautiously, and don't make any noise. I won't
+be responsible for what happens."
+
+"We'll take all the risk," interrupted Tom.
+
+"All right. Now there's a couple of lanterns around here. I'll
+light them, and leave you for a while until I can get some grub.
+I'll be back as soon as I can."
+
+He glided away, after lighting two lanterns, by the gleams of
+which the adventurers could see that they were in a vaulted
+cavern that had evidently been fitted up as a living apartment.
+The sides, roof and floor were of stone. It was clean, and the
+air was fresh. There were some chairs, a table, and several cots,
+with pieces of bagging for bedding, though it was warm in the
+place.
+
+"I guess we can stay here until we discover the secret," spoke
+Tom.
+
+"Bless my watch! We can if we have something to eat," came from
+Mr. Damon, with something like a sigh. "I'm hungry!"
+
+"And I want to make some observations," said Mr. Parker. "From
+what I have seen of this mountain, I would not be surprised if
+this cave was to be suddenly destroyed by a landslide or a
+lightning bolt. I will make some further investigations."
+
+"Well, if it's going to cause you to make such gloomy
+prophecies as that, I'd just as soon you wouldn't look any
+further," spoke Tom, in a low voice. But Mr. Parker, taking one
+of the lanterns, set about examining the rock of which the cave
+consisted.
+
+In a short time Bill Renshaw returned with enough food to last
+for two days. He said he was going out on the mountain once more
+to act the part of a lookout, and would visit the adventurers
+again the next day.
+
+"In the meanwhile you can do just as you please," he said.
+"Nobody is likely to disturb you here, and you can sneak up and
+take a look at the men in the other cave whenever you're ready.
+Only be careful--that's all I've got to say. They're desperate
+men."
+
+It was not very pleasant, eating in the gloomy cavern, but they
+made the best of it. They cooked on a small oil-stove they found
+in the place, and after some hot coffee they felt much better.
+
+"Well," remarked Tom, after a while, "shall we take a chance,
+and go look at the men at work?"
+
+"I think so," answered Mr. Jenks. "The sooner we discover this
+mystery, the better. Then we can go back home."
+
+"And recover my airship," added Tom, who was a bit uneasy
+regarding the safety of the Red Cloud.
+
+"Then, bless my finger-rings! let's go and see if we can find
+the big cave your friend the ghost told us of," suggested Mr.
+Damon.
+
+Cautiously they made their way along the passage Bill had
+pointed out. As they went forward the subdued noise became
+louder, and finally they could feel the vibration of machinery.
+
+"This is the place," whispered Mr. Jenks. "That sound we hear
+is one of the mixing machines, for grinding the materials--carbon
+and the other substances--which go to make up the diamonds. I
+remember hearing that when I was in the cave before."
+
+"Then we must be near the place," observed Tom.
+
+"Yes, but I didn't have much chance to look around when I was
+here before. They wouldn't let me. I never even knew of the small
+cave Bill took us to."
+
+"Well, if we're close to it, we'd better go cautiously, and not
+talk any more than we're obliged to," suggested Mr. Parker, and
+they agreed that this was good advice.
+
+They walked on softly. Suddenly Tom, who was in the lead, saw a
+gleam of light.
+
+"We're here," he whispered. "I'll put out our lantern, now,"
+which he did. Then, stealing forward he and the others beheld a
+curious sight. The tunnel they were in ended at a small hole
+which opened into a large cavern, and, fortunately, this opening
+was concealed from the view of those in the main place.
+
+"The diamond makers!" whispered Tom, hoarsely, pointing to
+several men grouped about a number of strange machines.
+
+"Yes--the very place where I was," answered Mr. Jenks, "and
+there is the apparatus--the steel box--from which the diamonds
+are taken--now to see how they make them."
+
+Fascinated, the adventurers looked into the cave. The men there
+were unaware of the presence of our friends, and were busily
+engaged. Some attended to the grinding machine, the roar and
+clatter of which made it possible for Tom and the others to talk
+and move about without being overheard. Into this machine certain
+ingredients were put, and they were then pulverized, and taken
+out in powdery form.
+
+The power to run the mixing machine was a gasoline motor, which
+chug-chugged away in one corner of the cave.
+
+As the powder was taken out, other men fashioned it into small
+balls, which were put on pan, and into a sort of oven, that was
+heated by a gasoline stove.
+
+"Is that how they make the diamonds?" asked Mr. Damon.
+
+"That is evidently the first step," said Mr. Jenks. "Those
+balls of powdered chemicals are partly baked, and then they are
+put into the steel box. In some way terrific heat and pressure
+are applied, and the diamonds are made. But how the heat and
+pressure are obtained is what we have yet to learn."
+
+He paused to watch the men at work. They were all busy, some
+attending to the machines, and others coming and going in and out
+of the cave. In one part a man was apparently getting ready a
+meal.
+
+Suddenly there rushed into the cave a man who seemed much
+excited.
+
+"Are you nearly ready with that stuff?" he cried. "There's a
+good storm gathering on the mountain!"
+
+"Yes, we'll be ready in half an hour," answered one of the men
+at the mixing machine.
+
+"Good. It will be flashing lightning bolts then, and we can see
+what luck we have. The last batch was a failure." The man hurried
+out again. Mr. Parker touched Tom and Mr. Jenks on their
+shoulders.
+
+"What is it?" asked Tom.
+
+"I know the secret of making the diamonds," said the scientist.
+
+"What?" cried Mr. Jenks.
+
+"It is by the awful power of the lightning bolts!" whispered
+Mr. Parker. "Everything is explained now--the reason why they
+make diamonds in this lonely place, near the top of the mountain.
+They need a place where the lightning is powerful. I can
+understand it now--I suspected it before. They make diamonds by
+lightning!"
+
+"Are you sure?" cried Mr. Jenks.
+
+"Positive."
+
+"I agree with you," said Tom Swift. "I was just getting on that
+track myself, when I saw the electric wires running to the steel
+box. That explains the upright rod on the top of the mountain.
+The man says a storm is coming--very well; we'll stay here and
+watch them make diamonds!"
+
+As he spoke there came the mutter of thunder, and the mountain
+vibrated slightly. The men in the cave redoubled their activity.
+Tom and his friends felt that the secret process they had so long
+sought was about to be demonstrated before their eyes.
+
+
+
+CHAPTER XXI--FLASHING GEMS
+
+
+Eagerly the adventurers looked through the opening at the end
+of the passage into the larger cave. The men opened the small
+oven in which the balls of white chemicals and carbon mixed, had
+been baked, and a pile of things, that looked like irregularly-shaped
+marbles, were placed in the steel box.
+
+This box, which was about the size of a trunk, was of massive
+metal. It was placed in a recess in the solid rock, and all about
+were layers of asbestos and other substances that were nonconductors
+of heat.
+
+"That box becomes red hot," exclaimed Mr. Jenks, in a whisper.
+"When things are in readiness, that lever is pulled and the
+diamonds are made. I pulled it once, but I did not then know the
+process involved. I supposed that the lightning had nothing to do
+with making the diamonds."
+
+"It has--a most important part," said Mr. Parker. The hidden
+adventurers could talk in perfect safety now, for the men in the
+large cave were too excited to pay much attention to them. The
+muttering of the thunder grew louder, and at times a particularly
+loud crash told that a bolt had struck somewhere in the vicinity
+of the cave.
+
+"But, bless my watch-charm!" exclaimed Mr. Damon, "I didn't
+know lightning made diamonds."
+
+"It does not--always," went on the scientist. "But great heat
+and pressure are necessary to create the gems. In nature this was
+probably obtained by prehistoric volcanic fires, and by the
+terrific pressure of immense rocks. It is possible to make
+diamonds in the laboratory of the chemist, but they are so minute
+as to be practically valueless.
+
+"However, these men seem to have hit upon a new plan. They
+utilize the terrific heat of lightning, and the pressure which is
+instantaneously obtained when the bolt strikes. I am anxious to
+see how it is done. Look, I think they are getting ready to make
+the gems."
+
+Indeed there seemed to be an air of expectancy among the
+diamond makers. The mixing machine had now been stopped, and, as
+it was more quiet in the cave, our friends, in their hiding-place,
+had to speak in mere whispers. All the men were now gathered
+about the great steel box.
+
+This receptacle had been closed by a solid metal door, which
+was screwed and clamped tight. Then one of the men examined a
+number of heavily insulated electric wires that extended from the
+box off into the darkness where Tom and his companions could not
+discern them.
+
+"That's Folwell--the man I befriended, and who got me into this
+game," whispered Mr. Jenks. "He was also one of the first to turn
+against me. I think he's one of the leaders."
+
+Folwell came back, after having gone into a dark part of the
+cave. He went over to an electrical switch on one of the stone
+walls.
+
+"It's almost time," Tom heard him say to his confederates. "The
+storm is coming up rapidly."
+
+"Will it be severe enough?" asked one of the helpers. "We had
+all our work for nothing last time. The flashes weren't heavy
+enough."
+
+"These will be," asserted Folwell. "The indicator shows nearly
+a million volts now, and it's increasing."
+
+"A million volts!" exclaimed Tom. "I hope it doesn't strike
+anywhere around here."
+
+"Oh, it will probably be harmlessly conducted down on the heavy
+wires," said Mr. Parker. "We are in no danger, at present, though
+ultimately I expect to see the whole mountain shattered by a
+lightning bolt."
+
+"Cheerful prospect," murmured Tom.
+
+There was a terrific crash outside. The rocky floor of the cave
+trembled.
+
+"Here she comes!" cried Folwell. "Get back, everybody! I'm
+going to throw over the switch now!"
+
+The men retreated well away from the steel box. Folwell threw
+over the lever--the same one Mr. Jenks remembered pulling. Then
+the man ran to the electric switch on the wall, and snapped that
+into place, establishing a connection.
+
+There was a moment's pause, as Folwell ran to join the others
+in their place of safety. Then from without there came a most
+nerve-racking and terrifying crash. It seemed as if the very
+mountain would be rent into fragments.
+
+Watching with eager eyes, the adventurers saw sparks flash from
+the steel box. Instantly it became red hot, and then glowed white
+and incandescent. It was almost at the melting point.
+
+Then came comparative quiet, as the echoes of the thunder died
+away amid the mountain peaks.
+
+"I guess that did the trick!" cried Folwell. "It was a terrific
+crash all right!"
+
+He and the others ran forward. The steel box was now a cherry
+red, for it was cooling. Folwell threw back the lever, and
+another man disconnected the switch. There was a period of
+waiting until the box was cool enough to open. Then the heavy
+door was swung back.
+
+With a long iron rod Folwell drew something from the retort. It
+was the tray which had held the white balls. But they were white
+no longer, for they had been turned into diamonds. From their
+hiding-place Tom and the others could see the flashing gems, for,
+in spite of the fact that the diamonds were uncut, some of them
+sparkled most brilliantly, due to the peculiar manner in which
+they were made.
+
+"We have the secret of the diamonds!" whispered Mr. Jenks.
+"There must be a quart of the gems there!"
+
+The men gathered about Folwell, uttering exclamations of
+delight. The diamonds were too hot to handle yet.
+
+"That's going some!" exclaimed the chief of the diamond makers.
+"We have a small fortune here."
+
+The was a sudden commotion at one end of the cave. A man rushed
+in. At the sight of him Tom stared and uttered an exclamation.
+
+"Munson--the stowaway!" he whispered.
+
+"Hello!" cried Folwell, as he saw his confederate. "I thought
+you were East, keeping Jenks away from here."
+
+"He got the best of me!" cried Munson, "he and that Tom Swift!
+I stowed away on their airship, but they found me out by a
+wireless message, and marooned me in the woods. I've been trying
+to get here ever since! Didn't you get my messages of warning?"
+
+"No--what warnings ?" cried Folwell.
+
+"About Jenks, Tom Swift and the others. They're here--they must
+be on Phantom Mountain now. In fact, I shouldn't be surprised if
+they were in this cave. I traced them to their camp, but they're
+gone. They may be among us now--in some of the secret recesses!"
+
+For an instant Folwell stared at the bearer of these tidings.
+Then he cried out:
+
+"Scatter men, and find these fellows! We must get them before
+they discover our secret!"
+
+"It's too late--we know it!" exulted Tom Swift. Then he
+whispered to the others to hurry to the part of the cave where
+Bill Renshaw had first hidden them.
+
+
+
+
+CHAPTER XXII--PRISONERS
+
+
+"Do you think there is any danger of them finding us?" asked
+Mr. Damon, as he hurried along beside Tom.
+
+"I'm afraid so," was the answer. "I've been worried ever since
+we saw Munson heading this way. But we couldn't do any differently."
+
+"Perhaps Bill Renshaw may be able to conceal us," suggested Mr.
+Jenks. "Very likely he knows that Munson is on hand. Perhaps we
+will be safe for a while. I want to make a few more observations
+as to how they manufacture the diamonds, and then, with what I
+already know, I'll have the secret."
+
+"And I'd like to make some scientific tests of the sides and
+bottom rocks of the cave," spoke Mr. Parker. "I think it will
+bear out my theory that the mountain will soon be destroyed."
+
+"Well, you were right about Earthquake Island, and you may be
+right about this mountain," said Tom, "but if it is going to be
+annihilated I hope we get far enough away from it."
+
+"We can keep our presence here a secret for a few more days, I
+think that will be long enough," proceeded Mr. Jenks. "Then we
+will leave."
+
+"And, in the meanwhile, they'll be searching for us," objected
+Mr. Damon. "I wish that ghost-chap would come back and tell us
+what to do. Bless my liver-pin, but we are going to be in
+considerable danger, I'm afraid! Those men may capture us, and
+decide to make diamond dust from us."
+
+"Come on--hurry to the little cave," urged Tom. "Then we'll get
+ready to defend ourselves."
+
+"The main cave is a large one," said Mr. Jenks, "and there are
+many hiding places in it. In fact, it is so large that it will
+take those fellows several days to complete a circuit of it. By
+that time Bill Renshaw may come back, and take us to some place
+in which they have already searched for us. Then we'll be
+comparatively safe."
+
+This thought was some consolation to them, as they made their
+way through the dark passage, dimly illuminated by the lantern
+they had rekindled, to the place where Bill had hidden them. They
+found things as they had left them, and proceeded to get a meal,
+though Tom said it would be best not to cook anything, or even to
+make coffee, for fear the odors would enable the searchers to
+trail them.
+
+So they ate cold food, glad to get that. Silently they sat
+about the dimly-lighted cavern, and discussed the situation. True
+they might even now retreat, going out of the entrance Bill had
+showed them, and so escape. But Mr. Jenks felt that his mission
+was not completed yet, and they all agreed to stay with him.
+
+"For there are several points about making diamonds that are
+not quite clear to me," he said. "I need to know how that steel
+box is constructed, how the electrical switches are arranged,
+what kind of lightning rods they use, and how they regulate the
+pressure. The other things, and how to mix the ingredients, I
+already know."
+
+"Then we'll do our best to help you," promised Tom. "But now I
+think we had better see what sort of a defense we can put up. We
+have our guns and revolvers, and with these chairs and tables we
+can build a sort of barricade behind which we can take refuge if
+those fellows do discover our hiding place."
+
+This was conceded to be a good idea, and soon a rude sort of
+fort was made, behind which the adventurers could take their
+stand and fight, if necessary, though they hoped this would not
+come to pass.
+
+They remained quietly in the cave the remainder of that day,
+and, when it was night, as they could tell by their timepieces--there
+was no daylight--they divided the hours into watches, taking turns
+standing guard.
+
+Morning, at least in point of time, came without any
+disturbance, and they made a cold breakfast. They hoped that Bill
+Renshaw would come, but he did not appear.
+
+After sitting in the dark cave until afternoon, Tom said:
+
+"I think we might as well go and take another observation of
+the big cave. We can tell what the men are doing, then, for they
+don't seem to have been near us. Maybe they have given up the
+search for us, and we can see them at work, and Mr. Jenks can
+gain what further knowledge he needs."
+
+"That will be a good plan," agreed the diamond man. "It's
+maddening to sit here, doing nothing."
+
+"And it will be comparatively safe to go from here to our
+former post of observation," added Tom, "for there doesn't seem
+to be any opening along the tunnel, into the larger cave, except
+the place where we were."
+
+Accordingly they started off. Cautiously they looked through
+the opening into the apartment where they had seen the diamonds
+made.
+
+"There's not a soul here!" exclaimed Tom, in a whisper. The
+others looked. The place was deserted--the machinery silent. Mr.
+Jenks peered in for a moment, and then exclaimed:
+
+"I'm going in! Now's my chance to find out all that I wish to
+know! It may never come again, and then we can soon leave Phantom
+Mountain!"
+
+It was a daring plan, but it seemed to be the best one to
+follow. They were all tired of inactivity. Mr. Jenks managed to
+get through the opening, and dropped into the big cave. The
+others followed. Mr. Jenks hurried over to the steel box, and
+began an examination of it. Tom Swift was looking at the
+electrical switch. He saw how it was constructed. Mr. Damon and
+Mr. Parker were peering interestedly about.
+
+Suddenly the sound of voices was heard, and the echo of
+footsteps. Mr. Jenks started.
+
+"They're coming back!" he whispered hoarsely. "Run!"
+
+They all turned and sped toward their hiding place. But they
+were too late. An instant later Folwell, Munson and the other
+diamond makers confronted them. Our friends made a bold rush, but
+were caught before they could go ten feet.
+
+"We have them!" cried Munson. "They walked right into our
+hands!"
+
+It was true. Tom Swift and the others were the prisoners of the
+diamond makers.
+
+
+
+CHAPTER XXIII--BROKEN BONDS
+
+
+"Well," remarked Tom Swift, in mournful tones, "this looks as
+if we were up against it; doesn't it?"
+
+"Bless my umbrella, it certainly does," agreed Mr. Damon.
+
+"And it's all my fault," said Mr. Jenks. "I shouldn't have gone
+into the big cave. I might have known those men would come back
+any time."
+
+The above conversation took place as our friends lay securely
+bound in a small cave, or recess, opening from the larger cavern,
+where, about an hour before, they had been captured and made
+prisoners by the diamond makers. Despite their struggles they had
+been overpowered and bound, being carried to the cave, where they
+were laid in a row on some old bags.
+
+"It certainly is a most unpleasant situation, to say the
+least," observed Mr. Parker.
+
+"And all my fault," repeated Mr. Jenks.
+
+"Oh, no it isn't," declared Tom Swift, quickly. "We were just
+as ready to follow you into that cave as you were to go. No one
+could tell that the men would return so soon. It's nobody's
+fault. It's just our bad luck."
+
+From where he lay, tied hand and foot, the young inventor could
+look out into the cave where he and the others had been caught.
+The diamond makers were busily engaged, apparently in getting
+ready to manufacture another batch of the precious stones. They
+paid little attention to their captives, save to warn them, when
+they had first been taken into the little cave, that it was
+useless to try to escape.
+
+"They needn't have told us that," observed Tom, as he and the
+others were talking over their situation in low voices. "I don't
+believe any one could loosen these ropes."
+
+"They certainly are pretty tight," agreed Mr. Damon. "I've been
+tugging and straining at mine for the last half hour, and all
+I've succeeded in doing is to make the cords cut into my flesh."
+
+"Better give it up," advised Mr. Jenks.
+
+"We'll just have to wait."
+
+"For what?" the scientist wanted to know.
+
+"To see what they'll do with us. They can't keep us here
+forever. They'll have to let us go some time." Following their
+capture, Folwell and Munson, the latter the stowaway of the
+airship, had been in earnest conversation regarding our friends,
+but what conclusion they had reached the adventurers could only
+guess.
+
+"And we didn't have time to examine the diamond-making
+machinery close enough so that we could duplicate it if
+necessary," complained Tom, a little later.
+
+"No," agreed Mr. Jenks. "There are certain things about it that
+are not clear to me. Well, I don't believe I'll have another
+chance to inspect it. They'll take good care of that, though they
+seem to be getting ready to make more diamonds."
+
+"Perhaps they're going to manufacture a big batch, and then
+leave this place," suggested Mr. Damon. "They will probably go to
+some other secret cave, and leave us here."
+
+"I hope they untie us before they leave, and give us something
+to eat," remarked the young inventor.
+
+For two hours longer the captives lay there, in most
+uncomfortable positions. Then Folwell and Munson, leaving the
+group of diamond makers who were grouped about the machinery,
+approached the captives.
+
+"Well," remarked Munson, "we got ahead of you after all; didn't
+we. You thought you had our secret, but it will be a long while
+before you ever make diamonds."
+
+"What are you going to do with us?" asked Tom.
+
+"Never mind. You came where you had no right to, and you must
+take the consequences."
+
+"We did have a right to come here!" exclaimed Mr. Jenks. "I am
+entitled to know how the diamonds are made. I paid for the
+information, and you tricked me. If ever it's possible I'll have
+the whole gang arrested for swindling."
+
+"You'll never get the chance!" declared Folwell. "You were
+given some diamonds for the money you invested, and that makes us
+square."
+
+"No, it doesn't!" declared Mr. Jenks. "I invested the money to
+learn how to make diamonds, and you know it! You tricked me, and
+I had a right to try to discover your secret! I nearly have it,
+too, and I'll get it completely before I'm done with you!"
+
+"No, you won't!" boasted Folwell. "But we didn't come here to
+tell you that. We came to give you something to eat. We're not
+savages and we'll treat you as well as we can in spite of the
+fact that you are trespassers. We're going to give you some grub,
+but I warn you that any attempt to escape will mean that some of
+you will get hurt."
+
+He signalled to some of his confederates. These men unbound the
+captives' arms, and stood over them while they ate some coarse
+food that was brought into the small cave. They were given coffee
+to drink, and then, when the simple meal was over, they were
+securely bound again, and left to themselves, while the diamond
+makers went back to their machinery.
+
+It was evident that they were going to attempt a big operation,
+for an unusually large quantity of the white stuff was prepared.
+The prisoners watched them idly. They could see some but not all
+of the operations. In this way several hours passed.
+
+Gloom possessed the hearts of Tom and his friends. Not only had
+their expedition been almost a failure so far, but the young
+inventor was worried lest the gang might discover and wreck his
+airship. This would prove a serious loss. Lying there in the
+semi-darkness the lad imagined all sorts of unpleasant happenings.
+
+At times he dozed off, as did the others. They had become
+somewhat used to the pain caused by the bonds, for their nerves
+were numb from the strain and pressure.
+
+Once, as he was lightly sleeping, Tom was awakened by hearing
+loud voices in the main cave. He looked out, rolling over
+slightly to get a better view. He saw the man who, once before
+had run in to give news of an approaching electrical storm.
+
+"Are you fellows all ready?" asked this same man again.
+
+"Yes. Is there another storm coming?"
+
+"Yes, and it's going to be a corker!" was the reply. "It's one
+of the worst I've ever seen. It's sweeping right up the valley.
+It'll be here in an hour."
+
+"That's good. We need a big flash to make all the material we
+have prepared into diamonds. It's the biggest batch we ever
+tried. I hope it succeeds, for we're going to leave--" The rest
+was in so low a tone that Tom could not catch it.
+
+The storm messenger departed. Folwell and Munson busied
+themselves about the machinery. Tom dozed off again, dimly
+wondering what had become of Bill Renshaw, and whether the former
+ghost knew of their plight. The others were asleep, as the young
+inventor saw by the dim light of a lantern in the cave. Then, he
+too, shut his eyes.
+
+Tom was suddenly awakened by feeling some one's hands moving
+about his clothing. At first he thought it was one of the
+diamond-making gang, who had sneaked in to rob him. "Here! What
+are you up to?" exclaimed Tom.
+
+"Quiet!" cautioned a voice. "Are you all here?"
+
+"All of us--yes. But who are you?"
+
+"Easy--keep quiet, Tom Swift! I'm Bill Renshaw! I've been
+searching all over for you, since I got back to your cave and
+found it empty. Now I'm going to free you. I got in here by a
+secret entrance. Wait, I'll cut your ropes." There was a slight
+sound, and an instant later Tom was freed from his bonds.
+
+
+
+
+CHAPTER XXIV--IN GREAT PERIL
+
+
+The young inventor could scarcely believe the good luck that
+had so unexpectedly come to him and his companions. No sooner was
+Tom able to move freely about than Bill Renshaw performed the
+same service for Mr. Jenks and the others, cautioning them to be
+quiet as he awakened them, and cut the ropes.
+
+"Bless my circulation!" exclaimed Mr. Damon, in a hoarse
+whisper. "How did you ever get here. I'd given ourselves up for
+lost."
+
+"Oh, I came in off the mountain, as there's a big storm due,"
+explained the man. "There was no need of me playing the haunt in
+daytime, anyhow. I went to the cave, found you and your things
+gone, and I surmised that you might have walked into some trap."
+
+"We did," admitted Mr. Jenks, grimly.
+
+"Well, I hunted around until I found you," went on Bill. "This
+mountain is honeycombed with caves, all opening from the large
+one, I know them better than these fellows do, so I could explore
+freely, and keep out of their sight. They didn't know that there
+was a second entrance to this place, but I did, and I made for
+it, when I couldn't find you in some of the other caves where I
+looked. And, sure enough, here you were."
+
+"Well, we can't thank you enough," said Mr. Parker. "But you
+say there is a big storm coming?"
+
+"One of the biggest that's been around these parts in some
+time," replied Bill.
+
+"Then perhaps the mountain will be destroyed," went on the
+scientist, as calmly as if he had remarked that it might rain.
+
+"I hope nothing like that happens until we get away," spoke Mr.
+Damon, fervently.
+
+"What had we better do?" inquired Tom.
+
+"Get away, unless you want to discover some more of their
+secrets," advised Bill. "Those fellows are planning something,
+but I can't find out what it is. They are suspicious of me, I
+think. But they are up to something, and I believe, it would be
+best for you to leave while you have the chance. It may not be
+healthy to stay. That's why I did my best to untie you."
+
+"We appreciate what you have done," declared Mr. Jenks, "but I
+want my rights. I must learn a few more facts about how to make
+diamonds from lightning flashes, and then I will have the same
+secret they cheated me out of. I think if we wait a while we may
+be able to see the parts of the process that are not quite clear
+to us. What do you say, Tom Swift?"
+
+"Well, I would like to learn the secret," replied the lad, "and
+if Bill thinks it's safe to stay here a while longer--"
+
+"Oh, I guess it will be safe enough," was the reply. "Those
+fellows won't bother about you now that they are about to make
+some more diamonds. Besides, they think you're all tied up. Yes,
+you can stay here and watch, I reckon. I've got a couple of guns,
+and--"
+
+"Then we'll stay," decided Tom. "We can put up a better fight
+now."
+
+Silently, in their prison, but which they could now leave
+whenever they pleased, the adventurers watched the diamond makers
+once more. The same process they had witnessed before was gone
+through with. The white balls were put inside the steel box and
+sealed up. Then they waited for the storm to reach its height.
+
+That this would not be long was evidenced by the mutterings of
+thunder which every moment grew louder. The outburst of
+electrical fury was likely to take place momentarily, and that it
+would be unusually severe was shown by the precautions taken by
+the diamond makers. They attached a number of extra wires, and
+brought out some insulated, hard rubber platforms, on which they
+themselves stood. Tom and Mr. Jenks were much interested in
+watching this detail of the work, and sought to learn how each
+part of the process was done.
+
+"I almost think we can make diamonds, Tom, when we get back to
+civilization," whispered Mr. Jenks.
+
+"I hope we can," answered Tom, "and we can't get back any too
+soon to suit me. I want to be in my airship again."
+
+"I don't blame you. But look, they are getting ready to adjust
+the switch."
+
+The adventurers ceased their whispered talk, and eagerly
+watched the diamond makers. Folwell and Munson were hurrying to
+and fro in the big cave, attending to the adjustments of the
+machinery.
+
+"On your insulated plates--all of you," Folwell gave the order.
+"This is going to be a terrific storm. The gage shows twice the
+power we have ever used, and it's creeping up every minute! We'll
+have more diamonds than ever had before!"
+
+"Yes, if the mountain isn't destroyed," added Mr. Parker, in a
+low voice. "I predict that it will be split from top to bottom!"
+
+"Comforting," thought Tom, grimly.
+
+"I guess we're all ready," said Folwell, in a low tone to
+Munson. "We'd better get insulated ourselves. I'm going to throw
+the switch."
+
+He did so. A moment later the man who had before given warning
+of the storm came dashing in. He was very much excited.
+
+"It's awful!" he cried. "The lightning is striking all over!
+Big rocks are being split like logs of wood!"
+
+"Well, it can't do any damage in here," said Munson. "We are
+well protected. Get on one of the plates," and he motioned to one
+of the hard-rubber platforms that was not occupied. The roar and
+rumble of the storm outside had given place to short terrific
+crashes. In their small cave the adventurers could feel the solid
+ground shake.
+
+A bluish light began dancing about the electrical wires. There
+was a smell of sulphur in the air. Crash after crash resounded
+outside. A flash of flame lit up the whole interior of the cave.
+It came from the copper switch.
+
+"Something's wrong with the insulation!" cried Munson.
+
+"Don't go near it!" yelled Folwell. "If you value your life,
+stand still!"
+
+Hardly had he spoken than inside the cavern there sounded a
+report like that of a small cannon. A big ball of fire danced
+about the middle of the cave and then leaped on top of the steel
+box.
+
+"This is a fearful storm," cried Munson.
+
+The adventurers in the cave did not know what to say or do.
+They were in deadly peril.
+
+Suddenly there came a crash louder than any that had preceded
+it. The whole side of the cave where the switches were was a mass
+of bluish flame. Then came a ripping, tearing sound, and a tangle
+of wires and copper connections were thrown to the floor. At the
+same time the steel box, containing the materials from which
+diamonds were made, turned blue, and flames shot from it.
+
+"It's all up with us!" cried Munson. "Run for it, everybody!
+The wires are down, and this place will be an electric furnace in
+another minute!"
+
+He leaped toward the exit from the cave.
+
+"What about those fellows?" asked Folwell, indicating the place
+where Tom and the others had been tied.
+
+"They'll have to do the best they can! It's every man for
+himself, now!" yelled Munson. There was a wild scramble from the
+cavern.
+
+"Come on!" cried Tom. "We must escape! It's our only chance!"
+
+He leaped into the big cave, followed by the others. Already
+long tongues of electrical fire were shooting out from the walls
+and roof as Tom Swift and his companions, evading them as best
+they could, sought safety in flight.
+
+
+
+CHAPTER XXV--THE MOUNTAIN SHATTERED--CONCLUSION
+
+
+"Can't we get some of the diamonds?" cried Mr. Damon, as he
+raced along behind Tom. "Now's our chance. Those fellows have all
+gone!" The odd man made a grab for something as he ran.
+
+"It's as much as our lives are worth," declared the young
+inventor. "We dare not stop! Come on!"
+
+"I'd like to investigate some of the machinery," spoke Mr.
+Jenks, "but I wouldn't stop, even for that."
+
+"The storm is too dangerous," called Bill Renshaw. "I can show
+you a shorter way out than the one those fellows have taken.
+Follow me."
+
+"No way can be too short," said Mr. Parker, solemnly. "This
+mountain will go to pieces shortly, I think!"
+
+Tom shuddered. He remembered how narrow had been their escape
+when Earthquake Island sank into the sea. And that some terrific
+upheaval was now imminent might be judged from the awful reports
+that sounded more plainly as the adventurers raced toward the
+opening of the cave. It was like the bombardment of some doomed
+city.
+
+Mr. Jenks and Tom cast one longing look behind at the
+complicated and expensive machinery that had been installed in
+the cave by the diamond makers. They had abandoned it, and in it
+lay the secret of making precious gems. But there was no time to
+stop now, and investigate.
+
+"This way," urged Bill Renshaw. "We'll soon be out."
+
+"But won't it be dangerous to go outside?" asked Mr. Damon.
+"Shan't we be struck by lightning? There is some protection in
+here."
+
+"None at all," said Mr. Parker, quickly. "This mountain is a
+natural lightning rod. To stay here in this cave will be sure
+death when the storm gets directly over it. And that will be very
+soon. We must get on insulated ground. Is there any part of this
+mountain that does not contain iron ore?" the scientist asked of
+the former spirit.
+
+"Yes; the way out by which we are going lands on a dirt hill."
+
+"That's good; then we may be saved."
+
+On they ran. They had no lanterns, but the blue light of the
+electricity, as it leaped from point to point inside the cave,
+where there were outcroppings of iron ore, made the place bright
+enough to see.
+
+"Here we are!" cried Bill Renshaw at length. "Here's the way
+out!"
+
+Making a sudden turn in the winding passage he showed the
+adventurers a small opening in the side of the crag. In an
+instant they had passed through, and found themselves in daylight
+once more. The sudden glare almost blinded them, for, though the
+sky was overcast by clouds, from which jagged tongues of
+lightning played, the outside was much lighter than the dark
+cave.
+
+"I should say it was a storm!" cried Tom Swift. "See, it is
+striking every minute, and all around us!"
+
+In fact, lightning bolts were falling on every side of the
+adventurers. Every time the balls of fire struck, they burst open
+great stones, or seared a livid scar on the face of some cliff.
+As for Tom and the others, they stood on a dry dirt hill, in
+which, fortunately, there was no iron ore. To this fact they
+undoubtedly owed their lives, though had there been rain, to
+moisten the ground and make the earth a good conductor of
+electricity, they probably would have been badly shocked. But the
+electrical outburst was not accompanied by rain.
+
+Tom looked up. He saw a compact mass of cloud moving toward the
+summit of the mountain on the slope of which they stood. From
+this cloud there played shafts of reddish-green fire.
+
+"Look!" called the young inventor to Mr. Parker. The instant
+the latter saw the cloud, he cried:
+
+"We must get away from here by all means! That is the center of
+the storm. As soon as it gets over the mountain, where that
+lightning rod is, all the electrical fluid will be discharged in
+one bolt at the mountain, and it will be destroyed! We must run,
+but keep on the dirt places! Run for your lives!"
+
+They needed no second warning. Turning, they fled down the
+steep side of the mountain, slipping and stumbling, but taking
+care not to step on any iron ore. Behind them flashed the
+lightning bolts.
+
+Suddenly there was a most awful crash. It seemed as if the end
+of the world had come, and the ear drums of Tom and his
+companion almost burst with the fearful report. The concussion
+knocked them down, and they lay stunned for a moment.
+
+Following the terrible report there was a low, rumbling sound.
+Hardly knowing whether he was dead or alive, Tom opened his eyes
+and looked about him. What he saw caused him to cry out in
+terror.
+
+The whole mountain seemed bathed in fire. Great blue, red and
+green flashes played around it. Then the towering cliff seemed to
+melt and crumble up, and the great peak, the top of it containing
+the diamond makers' cave, from which they had fled but a few
+minutes before, the entire summit was toppled over into the
+valley on the other side, and in the direction opposite to that
+where the adventurers stood.
+
+Then came a profound silence, and the lightning ceased. The
+storm was over, and only the rattle of stones and boulders, as
+they came to rest in the valley below, reached the ears of our
+friends.
+
+"Phantom Mountain has been destroyed, just as I said it would
+be," spoke Mr. Parker, solemnly. Once more he had prophesied
+correctly.
+
+For a few minutes the adventurers hardly knew what to say. They
+arose awkwardly from the ground where the shock had tossed them.
+Then Tom remarked, as calmly as possible:
+
+"Well, it's all over. I guess we may as well get back to our
+airship."
+
+"What became of Munson and the others?" asked Mr. Damon.
+
+Mr. Jenks pointed to the trail, far below. The figures of some
+men, running madly, could be seen.
+
+"There they go," he said; "I fancy we have seen the last of
+them." And they had, for some time at least.
+
+There was little use lingering any longer on Phantom Mountain--indeed
+little of it was left on which to remain. Looking back
+toward the place where the cave had been, Tom and the others
+started forward again. The diamond-making machinery had all been
+destroyed. So, also, had the finished diamonds stored in the
+cavern and the large supply which had probably been made by the
+last terrific crash. No one would ever have them now. Tom and Mr.
+Jenks felt a sense of disappointment, but they were glad to have
+escaped with their lives. They sought their former camp, but the
+tent and all their food was buried under tons of earth and rocks.
+
+Three days later, after rather severe hardships, they were near
+the place where they had left the Red Cloud. They had suffered
+cold and hunger, for they had no food supplies, and, had it not
+been that Bill Renshaw knew the haunts of some game, of which
+they managed to snare some, they would have fared badly, for they
+had left their guns in the cave.
+
+"Well, there are the trees behind which I hope my airship is
+hidden," announced Tom, as they came to the spot. "Good old Red
+Cloud! Maybe we won't do some eating when we get aboard, eh?"
+
+"Bless my appetite! but we certainly will!" cried Mr. Damon.
+
+"There's somebody walking around the place," spoke Mr. Jenks.
+
+"I hope it's no one who has damaged the ship," came from Tom,
+apprehensively. He broke into a run, and soon confronted an aged
+miner, who seemed to have established a rude sort of camp near
+the airship.
+
+"Is anything the matter?" asked Tom, breathlessly. "Is my
+airship all right?"
+
+"I guess she's all right, stranger," was the reply. "I don't
+know much about these contraptions, but I haven't touched her. I
+knowed she was an airship, for I've seen pictures of 'em, and
+I've been waiting until the owner came along."
+
+"Why?" asked Tom, wonderingly.
+
+"Because I've got a proposition to make to you," went on the
+miner, who said his name was Abe Abercrombie. "I've been a miner
+for a good many years, and I'm just back from Alaska, prospecting
+around here. I haven't had any luck, but I know of a gold mine
+in Alaska that will make us all rich. Only it needs an airship to
+get to it, and I've been figuring how to hire one. Then I comes
+along, and I sees this big one, and I makes up my mind to stay
+here until the owners come back. That's what I've done. Now, if I
+prove that I'm telling the truth, will you go to Alaska--to the
+valley of gold with me?"
+
+"I don't know," answered Tom, to whom the proposition was
+rather sudden. "We've just had some pretty startling adventures,
+and we're almost starved. Wait until we get something to eat, and
+we'll talk. Come aboard the Red Cloud," and the lad led the way
+to his craft which was in as good condition as when he left it to
+go to the diamond cave. Later he listened to the miner's story.
+
+Tom Swift did go to the valley of gold in Alaska, and what
+happened to him and his companions there will be told of in the
+next volume of this series, to be called "Tom Swift in the Caves
+of Ice; or, the Wreck of the Airship."
+
+It did not take our friends long, after they had eaten a hearty
+meal, to generate some fresh gas, and start the Red Cloud oh her
+homeward way. Tom wanted to take Bill Renshaw with him, but the
+old man said he would rather remain among the mountains where he
+had been born. So, after paying him well for his services, they
+said good-by to him. Abercrombie, the miner, also remained
+behind, but promised to call and see Tom in a few months.
+
+"Well, we didn't make any money out of this trip," observed Mr.
+Jenks, rather dubiously, as they were nearing Shopton, after an
+uneventful trip. "I guess I owe you considerable, Tom Swift. I
+promised to get you a lot of diamonds, but all I have are those I
+had from my first visit to the cave."
+
+"Oh, that's all right," spoke Tom, easily. "The experience was
+worth all the trip cost."
+
+"Speaking of diamonds, look here!" exclaimed Mr. Damon,
+suddenly, and he pulled out a double handful.
+
+"Where did you get them?" cried the others in astonishment.
+
+"I grabbed them up, as we ran from the cave," said the
+eccentric man; "but, bless my gaiters! I forgot all about them
+until you spoke. We'll share them."
+
+These diamonds, some of which were large, proved very valuable,
+though the total sum was far below what Mr. Jenks hoped to make
+when he started on the remarkable trip. Tom gave Mary Nestor a
+very fine stone, and it was set in a ring, instead of a pin, this
+time.
+
+On their arrival in Shopton, where Mr. Swift, the housekeeper,
+Mr. Jackson and Eradicate Sampson were much alarmed for Tom's
+safety, an attempt was made to manufacture diamonds, using a
+powerful electric current instead of lightning. But it was not a
+success, and so Mr. Jenks concluded to give up his search for the
+secret which was lost on Phantom Mountain.
+
+And now we will take leave of Tom Swift, to meet him again soon
+in other adventures he is destined to have in the caves of ice
+and the valley of gold.

+
+
+Project Gutenberg's Etext of Tom Swift Among the Diamond Makers
+*****This file should be named 07tom10.txt or 07tom10.zip******
+
+Corrected EDITIONS of our etexts get a new NUMBER, 07tom11.txt.
+VERSIONS based on separate sources get new LETTER, 07tom10a.txt.
+
+
+This Etext was prepared for Project Gutenberg by Anthony Matonac.
+
+
+We are now trying to release all our books one month in advance
+of the official release dates, for time for better editing.
+
+Please note: neither this list nor its contents are final till
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg Etexts is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so. To be sure you have an
+up to date first edition [xxxxx10x.xxx] please check file sizes
+in the first week of the next month. Since our ftp program has
+a bug in it that scrambles the date [tried to fix and failed] a
+look at the file size will have to do, but we will try to see a
+new copy has at least one byte more or less.
+
+
+Information about Project Gutenberg (one page)
+
+We produce about two million dollars for each hour we work. The
+fifty hours is one conservative estimate for how long it we take
+to get any etext selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. This
+projected audience is one hundred million readers. If our value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour this year as we release thirty-two text
+files per month: or 400 more Etexts in 1996 for a total of 800.
+If these reach just 10% of the computerized population, then the
+total should reach 80 billion Etexts.
+
+The Goal of Project Gutenberg is to Give Away One Trillion Etext
+Files by the December 31, 2001. [10,000 x 100,000,000=Trillion]
+This is ten thousand titles each to one hundred million readers,
+which is only 10% of the present number of computer users. 2001
+should have at least twice as many computer users as that, so it
+will require us reaching less than 5% of the users in 2001.

+We need your donations more than ever!

+
+
+<p>&quot;Well, Tom Swift, I don't believe you will make any mistake if
+you buy that diamond,&quot; said the jeweler to a young man who was
+inspecting a tray of pins, set with the sparkling stones. &quot;It is
+of the first water, and without a flaw.&quot;</p>
+
+<p>&quot;It certainly seems so, Mr. Track. I don't know much about
+diamonds, and I'm depending on you. But this one looks to be all
+right.&quot;</p>
+
+<p>&quot;Is it for yourself, Tom?&quot;</p>
+
+<p>&quot;Er&mdash;no&mdash;that is, not exactly,&quot; and Tom Swift, the young
+inventor of airships and submarines, blushed slightly.</p>
+
+<p>&quot;Ah, I see. It's for your housekeeper, Mrs. Baggert. Well, I
+think she would like a pin of this sort. True, it's rather
+expensive, but&mdash;&quot;</p>
+
+<p>&quot;No, it isn't for Mrs. Baggert, Mr. Track,&quot; and Tom seemed a
+bit embarrassed.</p>
+
+<p>&quot;No? Well, then, Tom&mdash;of course it's none of my affair, except
+to sell you a good stone, But if this brooch is for a young lady,
+I can't recommend anything nicer. Do you think you will take
+this; or do you prefer to look at some others?&quot;</p>
+
+<p>&quot;Oh, I think this will do, Mr. Track. I guess I'll take&mdash;&quot;</p>
+
+<p>Tom's Words were interrupted by a sudden action on the part of
+the jeweler. Mr. Track ran from behind the showcase and hastened
+toward the front door.</p>
+
+<p>&quot;Did you see him, Tom?&quot; he cried. &quot;I wonder which way he went?&quot;</p>
+
+<p>&quot;Who?&quot; asked the lad, following the shopkeeper.</p>
+
+<p>&quot;That man. He's been walking up and down in front of my place
+for the last ten minutes&mdash;ever since you've been in here, in
+fact, and I don't like his looks.&quot;</p>
+
+<p>&quot;What did he do?&quot;</p>
+
+<p>&quot;Nothing much, except to stare in here as if he was sizing my
+place up.&quot;</p>
+
+<p>&quot;Sizing it up?&quot;</p>
+
+<p>&quot;Yes. Getting the lay of the land, so he or some confederate
+could commit a robbery, maybe.&quot;</p>
+
+<p>&quot;A robbery? Do you think that man was a thief?&quot;</p>
+
+<p>&quot;I don't know that he was, Tom, and yet a jeweler has to be
+always on the watch, and that isn't a joke, either, Tom Swift.
+Swindlers and thieves are always on the alert for a chance to rob
+a jewelry store, and they work many games.&quot;</p>
+
+<p>&quot;I didn't notice any particular man looking in here,&quot; said Tom,
+who still held the diamond brooch in his hand.</p>
+
+<p>&quot;Well I did,&quot; went on the jeweler. &quot;I happened to glance out of
+the window when you were looking at the pins, and I saw his eyes
+staring in here in a suspicious manner. He may have a confederate
+with him, and, when you're gone, one may come in, and pretend to
+want to look at some diamonds. Then, when I'm showing him some,
+the other man will enter, engage my attention, and the first man
+will slip out with a diamond ring or pin. It's often done.&quot;</p>
+
+<p>&quot;You seem to have it all worked out, Mr. Track,&quot; observed the
+lad, with a smile. &quot;How do you know but what I'm in with a gang
+of thieves, and that I'm only pretending to want to buy a diamond
+pin?&quot;</p>
+
+<p>&quot;Oh, I guess I haven't known you, Tom Swift, ever since you
+were big enough to toddle, not to be sure about what you're up
+to. But I certainly didn't like the looks of that man. However,
+let's forget about him. He seems to have gone down the street,
+and, after all, perhaps I was mistaken. Just wait until I show
+you a few more styles before you decide. The young lady may like
+one of these,&quot; and the jeweler went to another showcase and took
+out some more trays of brooches.</p>
+
+<p>&quot;What makes you think she's a young lady, Mr. Track?&quot; asked the
+lad.</p>
+
+<p>&quot;Oh, it's easy guessing, Tom. We jewelers are good readers of
+character. I can size up a young fellow coming in here to buy an
+engagement or a wedding ring, as soon as he enters the door. I
+suppose you'll soon be in the market for one of those, Tom, if
+all the reports I hear about you are true&mdash;you and a certain Mary
+Nestor.&quot;</p>
+
+<p>&quot;I&mdash;er&mdash;I think I don't care for any of these pins,&quot; spoke Tom,
+quickly, with a blush. &quot;I like the first lot best. I think I'll
+take the one I had in my hand when that man alarmed you. Ha!
+That's odd! What did I do with it?&quot;</p>
+
+<p>Tom looked about on the showcase, and glanced down on the
+floor. He had mislaid the brooch, but the jeweler, with a laugh,
+lifted it out of a tray a moment later.</p>
+
+<p>&quot;I saw you lay it down,&quot; he said. &quot;We jewelers have to be on
+the watch. Here it is. I'll just put it in a box, and&mdash;&quot;</p>
+
+<p>With an exclamation, Mr. Track gave a hasty glance toward his
+big show window. Tom looked up, and saw a man's face peering in.
+At the sight of it, he, too, uttered a cry of surprise.</p>
+
+<p>The next instant the man outside knocked on the glass,
+apparently with a piece of metal, making a sharp sound. As soon
+as he heard it, the jeweler once more sprang from behind the
+showcase, and leaped for the door crying:</p>
+
+<p>&quot;There's the thief! He's trying to cut a hole through my show
+window and reach in and get something! It's an old trick. I'll
+get the police! Tom, you stay here on guard!&quot; and before the lad
+could utter a protest, the jeweler had opened the door, and was
+speeding down the street in the gathering darkness.</p>
+
+<p>Tom stared about him in some bewilderment. He was left alone in
+charge of a very valuable stock of jewelry, the owner of which
+was racing after a supposed thief, crying:</p>
+
+<p>&quot;Police! Help! Thieves! Stop him, somebody!&quot;</p>
+
+<p>&quot;This is a queer go,&quot; mused Tom. &quot;I wonder who that man was? He
+looked like somebody I know, and yet I can't seem to place his
+face. I wonder if he was trying to rob the placer Maybe there's
+another one&mdash;a confederate&mdash;around here.&quot;</p>
+
+<p>This thought rather alarmed Tom, so he went to the door, and
+looked up and down the street. He could see no suspicious
+characters, but in the direction in which the jeweler was running
+there was a little throng of people, following Mr. Track after
+the man who had knocked on the window.</p>
+
+<p>&quot;I wish I was there, instead of here,&quot; mused the lad. &quot;Still I
+can't leave, or a thief might come in. Perhaps that was the game,
+and one of the gang is hanging around, hoping the store will be
+deserted, so he can enter and take what he likes.&quot;</p>
+
+<p>Tom had read of such cases, and he at once resolved that he
+would not only remain in the jewelry shop, but that he would lock
+the door, which he at once proceeded to do. Then he breathed
+easier.</p>
+
+<p>The town of Shopton, in the outskirts of which Tom lived with
+his father, and where the scene above narrated took place, was
+none too well lighted at night, and the lad had his doubts about
+the jeweler catching the oddly-acting man, especially as the
+latter had a good start.</p>
+
+<p>&quot;But some one may head him off,&quot; reasoned Tom. &quot;Though if they
+do catch him, I don't see what they can prove against him. Hello,
+here I am carrying this diamond pin around. I might lose it.
+Guess I'll put it back on the tray.&quot;</p>
+
+<p>He replaced in the proper receptacle one of the pins he bad
+been examining when the excitement occurred.</p>
+
+<p>&quot;I wonder if Mary will like that?&quot; he said, softly. &quot;I hope she
+does. Perhaps it would be better if she could come here herself
+and pick out one&mdash;&quot;</p>
+
+<p>Tom's musing was suddenly interrupted by a sharp tattoo on the
+glass door of the jewelry shop. With a start, he looked up, to
+see staring in on him the face of the man who had been there
+before&mdash;the man of whom the jeweler was even then in chase.</p>
+
+<p>&quot;Why&mdash;why&mdash;&mdash;&quot; stammered Tom.</p>
+
+<p>The man knocked again.</p>
+
+<p>&quot;Tom&mdash;Tom Swift!&quot; he called. &quot;Don't you know me?&quot;</p>
+
+<p>&quot;Know you&mdash;you?&quot; repeated the lad.</p>
+
+<p>&quot;Yes&mdash;don't you remember Earthquake Island&mdash;how we were nearly
+killed there&mdash;don't you remember Mr. Jenks?&quot;</p>
+
+<p>&quot;Mr. Jenks?&quot;</p>
+
+<p>Tom was so startled that he could only repeat words after the
+strange man, who was talking to him from outside the glass door.</p>
+
+<p>&quot;Yes, Mr. Jenks,&quot; was the reply. &quot;Mr. Barcoe Jenks, who makes
+diamonds. I saw you in the store about to buy a diamond&mdash;I wanted
+to tell you not to&mdash;I'll give you a better diamond than you can
+buy&mdash;I just arrived in this place&mdash;I must have a private talk
+with you&mdash;Come out&mdash;I'll share a wonderful secret with you.&quot;</p>
+
+<p>A flood of memory came to Tom. He did recall the very strange
+man who walked around Earthquake Island&mdash;where Tom and some
+friends had been marooned recently&mdash;walked about with a pocketful
+of what he said were diamonds. Now Barcoe Jenks was here.</p>
+
+<p>&quot;I must see you privately, Tom Swift,&quot; went on Mr. Jenks, as he
+once more tapped on the glass. &quot;Don't waste money buying
+diamonds, when you and I can make better ones. Where can I have a
+talk with you? I&mdash;&quot; Mr. Jenks suddenly looked down the dimly-lighted
+street. &quot;They're coming back!&quot; he cried. &quot;I don't want to
+be seen. I'll call at your house later to-night&mdash;be on the watch
+for me&mdash;until then&mdash;good-by!&quot;</p>
+
+<p>He waved his hand, and was gone in an instant. Tom stood
+staring at the glass door. He hardly knew whether to believe it
+or not&mdash;perhaps it was all a dream.</p>
+
+<p>He pinched himself to make sure that he was awake. Very
+substantial flesh met his thumb and finger, and he felt the pain.</p>
+
+<p>&quot;I'm awake all right,&quot; he murmured. &quot;But Barcoe Jenks here&mdash;and
+still talking that nonsense about his manufactured diamonds. I
+think he must be crazy. I wonder&mdash;&quot;</p>
+
+<p>Once more the lad's musing was interrupted. He heard a murmur
+of excited voices outside the store, on the street. Then the door
+of the jewelry shop was tried. Mr. Track's face was pressed
+against the glass.</p>
+
+<p>&quot;Open the door! Let me in, Tom!&quot; he called. &quot;I've caught the
+thief,&quot; and as the lad unlocked the portal he saw that the
+jeweler held by the arm a ragged lad. &quot;Ah; you scoundrel! I've
+caught you!&quot; cried the diamond merchant, shaking the small chap,
+while Tom looked on, more mystified than ever.</p>

+<h2><a name="CHAPTER_II_A_MIDNIGHT_VISIT" id="CHAPTER_II_A_MIDNIGHT_VISIT" />CHAPTER II&mdash;A MIDNIGHT VISIT</h2>
+
+
+<p>While Mr. Track, the jeweler, and several citizens, attracted
+by the chase after the supposed thief, are crowded into the
+store, anxious to hear explanations of the strange affair, I will
+take the opportunity to tell you something of Tom Swift, the lad
+who is to figure in this story.</p>
+
+<p>Many of you have already made his acquaintance, when he has
+been speeding about in his airship or fast electric runabout, and
+to others we will state that our hero first made his bow to the
+public in the book called &quot;Tom Swift and His Motor-Cycle,&quot; the
+initial volume of this series.</p>
+
+<p>In that story there was related how Tom made the acquaintance
+of an odd individual, named Mr. Wakefield Damon, who was
+continually blessing himself, some part of his anatomy, or his
+possessions. Mr. Damon was riding a motor-cycle, and it started
+to climb a tree, to his pain and fright. Afterward Tom purchased
+the machine, and had many adventures on it, including a chase
+after a gang of men who had stolen a valuable patent model
+belonging to Mr. Swift.</p>
+
+<p>Mr. Swift, and his son were both inventors. They lived together
+in a fine house in the suburbs of Shopton, New York, and with
+them dwelt Mrs. Baggert, the housekeeper (for Tom's mother was
+dead), and also Garret Jackson, an expert engineer, who aided the
+young inventor and his father in perfecting many machines.</p>
+
+<p>There was also another semi-member of the household, to wit,
+Eradicate Sampson, an eccentric colored man, who owned a mule
+called Boomerang. Eradicate did odd jobs around the place, and
+the mule assisted his owner&mdash;that is when the mule felt like it.</p>
+
+<p>In the second volume of the series, entitled &quot;Tom Swift and His
+Motor-Boat,&quot; there was related the incidents following a pursuit
+after a gang of unprincipled men, who sought to get Possession of
+some of Mr. Swift's patents, and it was while in this boat that
+Tom, his father, and a friend, Ned Newton, rescued from Lake
+Carlopa a Mr. John Sharp, who fell from his burning balloon. Mr.
+Sharp was a skilled aeronaut, and after his recovery he joined
+Tom in building a big airship, called the Red Cloud. Tom's
+adventures in this craft are set down in detail in the third
+volume of the series, called &quot;Tom Swift and His Airship.&quot; Not
+only did he and Mr. Sharp and Mr. Damon make a great trip, but
+they captured some bank robbers, and incidentally cleared
+themselves from the imputation of having looted the vault of
+seventy-five thousand dollars, which charge was fostered by a
+certain Mr. Foger, and his son Andy, who was Tom's enemy.</p>
+
+<p>Not satisfied with having conquered the air, Tom and his father
+set to work to gain a victory over the ocean. They built a boat
+that could navigate under water, and, in the fourth book of the
+series, called &quot;Tom Swift and His Submarine Boat,&quot; you will find
+an account of how they went under the ocean to secure a sunken
+treasure, and the fight they had with their enemies who sought to
+get it away from them. They went through many perils, not the
+least of which was capture by a foreign warship.</p>
+
+<p>In the fifth book, entitled &quot;Tom Swift and His Electric
+Runabout,&quot; there was told the story of a wonderfully speedy
+electric automobile the young inventor constructed, and how he
+made a great race in it, and saved from ruin a bank, in which his
+father and Mr. Damon were interested.</p>
+
+<p>Tom's ability as an inventor had, by this time, become well
+known. One day, as related in a volume called &quot;Tom Swift and His
+Wireless Message,&quot; he received a letter from a Mr. Hosmer
+Fenwick, of Philadelphia, asking his aid in perfecting an airship
+which the resident of the Quaker City had built, but which would
+not work. In his small monoplane, the Butterfly, Tom and Mr.
+Damon went to Philadelphia, as Mr. Damon was acquainted with Mr.
+Fenwick.</p>
+
+<p>Tom carefully inspected the Whizzer which was the name of Mr.
+Fenwick's airship, and, after some difficulties, succeeded in
+getting the electric craft in shape to make a flight.</p>
+
+<p>Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape
+May in the Whizzer, but were caught in a terrific storm, and
+blown out to sea. The wind became a hurricane, the airship was
+disabled, and wrecked in mid-air. When it fell to earth it landed
+on one of the small West Indian islands, but what was the terror
+of the three castaways to find that the island was subject to
+earthquake shocks.</p>
+
+<p>But the earth-tremors were not the only surprise in store for
+Tom and his two friends, On the island they found five men and
+two ladies, who, by strange chance, had been stranded there when
+the yacht Resolute, owned by Mr. George Hosbrook, was wrecked in
+the same storm that disabled the airship. Mr. Hosbrook, a
+millionaire, was taking a party of friends to the West Indies.</p>
+
+<p>When the castaways (among whom were Mr. and Mrs. Amos Nestor,
+parents of Mary Nestor, a girl of whom Tom was very fond) found
+that there was danger of the island being destroyed in an
+earthquake, they were in despair. There seemed no way of being
+rescued, as the island was out of the line of regular ship
+travel.</p>
+
+<p>Tom, however, was resourceful. With the electrical apparatus
+from the wrecked airship, he built a wireless plant, and sent
+messages for help, broadcast over the ocean.</p>
+
+<p>They were finally heard, and answered, by an operator on board
+the steamer Camberanian, which came on under forced draught, and
+rescued Tom and his friends. It was only just in time, for, no
+sooner had they gotten aboard the steamer in lifeboats, than the
+whole island was destroyed by an earthquake shock.</p>
+
+<p>But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick,
+and all the others, got safely home. Among the survivors from the
+yacht Resolute was a Mr. Barcoe Jenks, who now, most unexpectedly,
+had confronted Tom through the glass window of the jewelry
+store. Mr. Jenks was a peculiar man. Tom discovered this on Earthquake
+Island. Mr. Jenks carried with him some stones which he said were
+diamonds. He asserted that he had made them, but Tom did not know
+whether or not to believe this.</p>
+
+<p>When it seemed that the castaways would not be saved Mr. Jenks
+offered Tom a large sum in these same diamonds for some plan
+whereby he might escape the earthquakes. Mr. Jenks said there was
+a certain secret in connection with the manufactured diamonds
+that he had to solve&mdash;that he had been defrauded of his rights&mdash;and
+that a certain Phantom Mountain figured in it. But Tom, at that time,
+paid little attention to Mr. Jenks' talk. The time was to come,
+however, when he would attach much importance to it.</p>
+
+<p>When this story opens, Tom was more interested in Mr. Barcoe
+Jenks than in any one else, and was wondering what he wanted to
+see him about. The young inventor could not quite understand how
+Mr. Track, the jeweler, could come back with a lad he suspected
+of being a thief, when the person who had acted so suspiciously,
+and who had knocked on the glass, was the queer man, Mr. Jenks.</p>
+
+<p>&quot;Yes, Tom I caught him,&quot; the jeweler went on. &quot;I chased after
+him, and nabbed him. It was hard work, too, for I'm not a good
+runner. Now, you little rascal, tell me why you tried to rob my
+store?&quot; and the diamond merchant shook the lad roughly.</p>
+
+<p>&quot;I&mdash;I didn't try to rob your store,&quot; was the timid answer.</p>
+
+<p>&quot;Well, perhaps you didn't, exactly, but your confederates did.
+Why did you rap on the glass, and why were you staring in so
+intently?&quot;</p>
+
+<p>&quot;I wasn't lookin' in.&quot;</p>
+
+<p>&quot;Well, if it wasn't you, it was some one just like you. But why
+did you run when I raced down the street?&quot;</p>
+
+<p>&quot;I&mdash;I don't know,&quot; and the lad began to snivel. &quot;I&mdash;I jest ran&mdash;that's
+all&mdash;'cause I see everybody else runnin', an' I thought
+there was a fire.&quot;</p>
+
+<p>&quot;Ha! That's a likely story! You ran because you are guilty! I'm
+going to hand you over to the police.&quot;</p>
+
+<p>&quot;Did he get anything, Mr. Track?&quot; asked one of the men who had
+joined the jeweler in the chase.</p>
+
+<p>&quot;No, I can't say that he did. He didn't get a chance. Tom Swift
+was in here at the time. But this fellow was only waiting for a
+chance to steal, or else to aid his confederates.&quot;</p>
+
+<p>&quot;But, if he didn't take anything, I don't see how you can have
+him arrested,&quot; went on the man.</p>
+
+<p>&quot;On suspicion; that's how!&quot; asserted Mr. Track. &quot;Will some one
+get me a constable?&quot;</p>
+
+<p>&quot;I wouldn't call a constable,&quot; said Tom, quietly.</p>
+
+<p>&quot;Why not?&quot;</p>
+
+<p>&quot;Because that isn't the person who looked in your window.&quot;</p>
+
+<p>&quot;How do you know, Tom?&quot;</p>
+
+<p>&quot;Because that person came back while you were out. I saw him.&quot;</p>
+
+<p>&quot;You saw him? Did he try to steal any of my diamonds, Tom?&quot;</p>
+
+<p>&quot;No, I guess he doesn't need any.&quot;</p>
+
+<p>&quot;Why not?&quot; There was wonder in the jeweler's tone.</p>
+
+<p>&quot;Why, he claims he can make all he wants.&quot;</p>
+
+<p>&quot;Make diamonds?&quot;</p>
+
+<p>&quot;So he says.&quot;</p>
+
+<p>&quot;Why, he must be crazy!&quot; and Mr. Track laughed.</p>
+
+<p>&quot;Perhaps he is,&quot; admitted Tom, &quot;I'm only telling you what he
+says. He's the person who acted so suspiciously. He came back
+here, I'm telling you, while you were running down the street,
+and spoke to me.&quot;</p>
+
+<p>&quot;Oh, then you know him?&quot; The jeweler's voice was suspicious.</p>
+
+<p>&quot;I didn't at first,&quot; admitted Tom. &quot;But when he said he was Mr.
+Barcoe Jenks, I remembered that I had met him when I was cast
+away on Earthquake Island.&quot;</p>
+
+<p>&quot;And he says he can make diamonds?&quot; asked Mr. Track.</p>
+
+<p>&quot;What did he want of you?&quot; and the jeweler looked at Tom,
+quizzically.</p>
+
+<p>&quot;He wanted to have a talk with me,&quot; replied the lad, &quot;and when
+he saw me in your store, he tried to attract my attention by
+knocking on the glass.&quot;</p>
+
+<p>&quot;That's a queer way to do,&quot; declared Mr. Track. &quot;What did he
+want?&quot;</p>
+
+<p>&quot;I don't know exactly,&quot; answered Tom, not caring to go into
+details just then. &quot;But I'm sure, Mr. Track, that you've got the
+wrong person there. That lad never looked in the window, nor
+knocked on the glass.&quot;</p>
+
+<p>&quot;That's right&mdash;I didn't,&quot; asserted the captive.</p>
+
+<p>The jeweler looked doubtful.</p>
+
+<p>&quot;Why did you run?&quot; he asked.</p>
+
+<p>&quot;I told you, I thought there was a fire.&quot;</p>
+
+<p>&quot;That's right, I don't believe he's the fellow you want,&quot; put
+in another man. &quot;I was standing on the corner, near White's
+grocery store, and I noticed this lad. That was before I heard
+you yelling, and saw you coming, and then I joined in the chase.
+I guess the man you were after got away, Track.&quot;</p>
+
+<p>&quot;He did,&quot; asserted Tom. &quot;He came back here, a little while ago,
+and he ran away just now, as he heard you coming.&quot;</p>
+
+<p>&quot;Where did he go?&quot; asked the jeweler, eagerly.</p>
+
+<p>&quot;I don't know,&quot; answered Tom. &quot;Only you've got the wrong lad
+here.&quot;</p>
+
+<p>&quot;Well, perhaps I have,&quot; admitted the diamond merchant. &quot;You can
+go, youngster, but next time, don't run if you're not guilty.&quot;</p>
+
+<p>&quot;I thought there was a fire,&quot; repeated the lad, as he hurriedly
+slipped through the crowd in the store, and disappeared down the
+dark street.</p>
+
+<p>&quot;Well, I guess the excitement's all over, and, anyhow, you
+weren't robbed, Track,&quot; said a stout man, as he left the store.
+The others soon followed, and Tom and the jeweler were once more
+alone in the shop.</p>
+
+<p>&quot;Can you tell me something about this man, Tom?&quot; asked Mr.
+Track, eagerly. &quot;So he really makes diamonds. Who is he?&quot;</p>
+
+<p>&quot;I'd rather not tell&mdash;just now,&quot; replied the young inventor. &quot;I
+don't take much stock in him, myself. I think he's visionary. He
+may think he has made diamonds, and he may have made some stones
+that look like them. I'm very skeptical.&quot;</p>
+
+<p>&quot;If you could bring me some, Tom, I could soon tell whether
+they were real or not. Can you?&quot;</p>
+
+<p>The lad shook his head.</p>
+
+<p>&quot;I don't expect to see Mr. Jenks again,&quot; he said. &quot;He talked
+rather wildly about waiting to meet me, but that man is odd&mdash;crazy,
+perhaps&mdash;and I don't imagine I'll see him. He's harmless,but he's
+eccentric. Well, there was quite some excitement for a time.&quot;</p>
+
+<p>&quot;I should say there was. I thought it was a plan to rob me,&quot;
+and the jeweler began putting away the diamond pins. In fact, the
+excitement so filled the minds of himself and Tom that neither of
+them thought any more of the object of the lad's visit, and the
+young inventor departed without purchasing the pin he had come after.</p>
+
+<p>It was not until he was out on the street, walking toward his
+home, that the matter came back to his mind.</p>
+
+<p>&quot;I declare!&quot; he exclaimed. &quot;I didn't get that pin for Mary,
+after all! Well, never mind, I have a week until her birthday,
+and I can get it to-morrow.&quot;</p>
+
+<p>He walked rapidly toward home, for the weather looked
+threatening, and Tom had no umbrella. He was musing on the
+happenings of the evening when he reached his house. His father
+was out, as was Garret Jackson, the engineer; and Mrs. Baggert,
+the housekeeper, was entertaining a lady in the sitting-room, so,
+as Tom was rather tired, he went directly to his own room, and, a
+little later got into bed.</p>
+
+<p>It was shortly after midnight when he was awakened by hearing a
+rattling on the window of his room. The reason he was able to fix
+the time so accurately was because as soon as he awakened he
+pressed a little electric button, and it illuminated the face of
+a small clock on his bureau. The hands pointed to five minutes
+past twelve.</p>
+
+<p>&quot;Humph! That sounds like hail!&quot; exclaimed Tom, as he arose, and
+looked out of the casement. &quot;I wonder if any of the skylights of
+the airship shed are open? There might be some damage. Guess I'd
+better go out and take a look.&quot;</p>
+
+<p>He had mentally reasoned this far before he had looked out, and
+when he saw that the moon was brightly shining in a clear sky, he
+was a bit surprised.</p>
+
+<p>&quot;Why&mdash;that wasn't hail,&quot; he murmured. &quot;It isn't even raining. I
+wonder what it was?&quot;</p>
+
+<p>He was answered a moment later, for a shower of fine gravel
+from the walk flew up and clattered against the glass. With a
+start, Tom looked down, and saw a dark figure standing under an
+apple tree.</p>
+
+<p>&quot;Hello! Who's there?&quot; called the lad, after he had raised the
+sash.</p>
+
+<p>&quot;It's I&mdash;Mr. Jenks,&quot; was the surprising answer.</p>
+
+<p>&quot;Mr. Jenks?&quot; repeated Tom.</p>
+
+<p>&quot;Yes&mdash;Barcoe Jenks, of Earthquake Island.&quot;</p>
+
+<p>&quot;You here? What do you want?&quot;</p>
+
+<p>&quot;Can you come down?&quot;</p>
+
+<p>&quot;What for?&quot;</p>
+
+<p>&quot;Tom Swift, I've something very important to tell you,&quot; was the
+answer in a low voice, yet which carried to Tom's ears perfectly.
+&quot;Do you want to make a fortune for yourself&mdash;and for me?&quot;</p>
+
+<p>&quot;How?&quot; Tom was beginning to think more and more that Mr. Jenks
+was crazy.</p>
+
+<p>&quot;How? By helping me to discover the secret of Phantom Mountain,
+where the diamonds are made! Will you?&quot;</p>
+
+<p>&quot;Wait a minute&mdash;I'll come down,&quot; answered Tom, and he began to
+grope for his clothes in the dim light of the little electric
+lamp.</p>
+
+<p>What was the secret of Phantom Mountain? What did Mr. Jenks
+really want? Could he make diamonds? Tom asked himself these
+questions as he hastily dressed to go down to his midnight
+visitor.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_III_A_STRANGE_STORY" id="CHAPTER_III_A_STRANGE_STORY" />CHAPTER III&mdash;A STRANGE STORY</h2>
+
+
+<p>&quot;Well, Mr. Jenks,&quot; began Tom, when he had descended to the
+garden, and greeted the man who had acted so strangely on
+Earthquake Island, &quot;this is rather an odd time for a visit.&quot;</p>
+
+<p>&quot;I realize that, Tom Swift,&quot; was the answer, and the lad
+noticed that the man spoke much more calmly than he had that
+evening at the jewelry shop. &quot;I realize that, but I have to be
+cautious in my movements.&quot;</p>
+
+<p>&quot;Why?&quot;</p>
+
+<p>&quot;Because there are enemies on my track. If they thought I was
+seeking aid to discover the secret of Phantom Mountain, my life
+might pay the forfeit.&quot;</p>
+
+<p>&quot;Are you in earnest, Mr. Jenks?&quot;</p>
+
+<p>&quot;I certainly am, and, while I must apologize for awakening you
+at this unseemly hour, and for the mysterious nature of my visit,
+if you will let me tell my story, you will see the need of
+secrecy.&quot;</p>
+
+<p>&quot;Oh, I don't mind being awakened,&quot; answered Tom, good-naturedly,
+&quot;but I will be frank with you, Mr. Jenks. I hardly can believe what
+you have stated to me several times&mdash;that you know how diamonds
+can be made.&quot;</p>
+
+<p>&quot;I can prove it to you,&quot; was the quiet answer.</p>
+
+<p>&quot;Yes, I know. For centuries men have tried to discover the
+secret of transmuting base metals into gold, and how to make
+diamonds by chemical means. But they have all been failures.&quot;</p>
+
+<p>&quot;All except this process&mdash;the process used at Phantom
+Mountain,&quot; insisted the queer man. &quot;Do you want to hear my
+story?&quot;</p>
+
+<p>&quot;I have no objections.&quot;</p>
+
+<p>&quot;Then let me warn you,&quot; went on Mr. Jenks, &quot;that if you do hear
+it, you will be so fascinated by it that I am sure you will want
+to cast your lot in with mine, and aid me to get my rights, and
+solve the mystery. And I also want to warn you that if you do,
+there is a certain amount of danger connected with it.&quot;</p>
+
+<p>&quot;I'm used to danger,&quot; answered Tom, quietly. &quot;Let me hear your
+story. But first explain how you came to come here, and why you
+acted so strangely at the jewelry store.&quot;</p>
+
+<p>&quot;Willingly. I tried to attract your attention at the store,
+because I saw that you were going to buy a diamond, and I didn't
+want you to.&quot;</p>
+
+<p>&quot;Why not?&quot;</p>
+
+<p>&quot;Because I want to present you with a beautiful stone, that
+will answer your purpose as well or better, than any one you
+could buy. That will prove my story better than any amount of
+words or argument. But I could not attract your attention without
+also attracting that of the jeweler. He became suspicious, gave
+chase, and I thought it best to vanish. I hope no one was made to
+suffer for what may have been my imprudence.&quot;</p>
+
+<p>&quot;No, the lad whom Mr. Track caught was let go. But how did you
+happen to come to Shopton?&quot;</p>
+
+<p>&quot;To see you. I got your address from the owner of the yacht
+Resolute. I knew that if there was one person who could aid me to
+recover my rights, it would be you, Tom Swift. Will you help me?
+Will you come with me to discover the secret of Phantom Mountain?
+If we go, it will have to be in an airship, for in no other way,
+I think, can we come upon the place, as it is closely guarded.
+Will you come? I will pay you well.&quot;</p>
+
+<p>&quot;Perhaps I had better hear your story,&quot; said the young
+inventor. &quot;But first let me suggest that we move farther away
+from the house. My father, or Mr. Jackson, or the housekeeper,
+may hear us talking, and it may disturb them. Come with me to my
+private shop,&quot; and Tom led the way to a small building where he
+did experimental work. He unlocked the door with a key he
+carried, turned on the lights, which were run by a storage
+battery, and motioned Mr. Jenks to a seat.</p>
+
+<p>&quot;Now I'll hear your story,&quot; said Tom.</p>
+
+<p>&quot;I'll make it as short as possible,&quot; went on the queer man. &quot;To
+begin with, it is now several years ago since a poorly dressed
+stranger applied to me one night for money enough to get a meal
+and a bed to sleep in. I was living in New York City at the time,
+and this was midnight, as I was returning home from my club.</p>
+
+<p>&quot;I was touched by the man's appearance, and gave him some
+money. He asked for my card, saying he would repay me some day. I
+gave it to him, little thinking I would hear from the man again.
+But I did. He called at my apartments about a week later, saying
+he had secured work as an expert setter of diamonds, and wanted
+to repay me. I did not want to take his money, but the fact that
+such a sorry looking specimen of manhood as he had been when I
+aided him, was an expert handler of gems interested me. I talked
+with the man, and he made a curious statement.</p>
+
+<p>&quot;This man, who gave his name as Enos Folwell, said he knew a place
+where diamonds could be made, partly in a scientific manner, and
+partly by the forces of nature. I laughed at him, but he told me so
+many details that I began to believe him. He said he and some other
+friends of his, who were diamond cutters, had a plant in the midst of
+the Rocky Mountains, where they had succeeded in making several small,
+but very perfect diamonds. They had come to the end of their rope,
+though, so to speak, because they could not afford to buy the materials
+needed. Folwell said that he and his companions had temporarily
+separated, had left the mountain where they made diamonds, and agreed
+to meet there later when they had more money with which to purchase
+materials. They had all agreed to go out into civilization, and work
+for enough funds to enable them to go on with their diamond making.</p>
+
+<p>&quot;I hardly knew whether to believe the man or not, but he
+offered proof. He had several small, but very perfect diamonds
+with him, and he gave them to me, to have tested in any way I
+desired.</p>
+
+<p>&quot;I promised to look into the matter, and, as I was quite
+wealthy, as, in fact I am now, and if I found that the stones he
+gave me were real, I said I might invest some money in the
+plant.&quot;</p>
+
+<p>&quot;Were the diamonds good?&quot; asked Tom, who was beginning to be
+interested.</p>
+
+<p>&quot;They were&mdash;stones of the first water, though small. An expert
+gem merchant, to whom I took them, said he had never seen any
+diamonds like them, and he wanted to know where I got them. Of
+course I did not tell him.</p>
+
+<p>&quot;To make a long story short, I saw Folwell again, told him to
+communicate with his companions, and to tell them that I would
+agree to supply the cash needed, if I could share in the diamond
+making. To this they agreed, and, after some weeks spent in
+preparation, a party of us set out for Phantom Mountain.&quot;</p>
+
+<p>&quot;Phantom Mountain?&quot; interrupted Tom. &quot;Where is it?&quot;</p>
+
+<p>&quot;I don't know, exactly&mdash;it's somewhere in the Rockies, but the
+exact location is a mystery. That is why I need your help. You
+will soon understand the reason. Well, as I said, myself, Folwell
+and the others, who were not exactly prepossessing sort of men,
+started west. When we got to a small town, called Indian Ridge,
+near Leadville, Colorado, the men insisted that I must now
+proceed in secret, and consent to be blindfolded, as they were
+not yet ready to reveal the secret of the place where they made
+the diamonds.</p>
+
+<p>&quot;I did not want to agree to this, but they insisted, and I gave
+in, foolishly perhaps. At any rate I was blindfolded one night,
+placed in a wagon, and we drove off into the mountains. After
+traveling for some distance I was led, still blindfolded, up a
+steep trail.</p>
+
+<p>&quot;When the bandage was taken off my eyes I saw that I was in a
+large cave. The men were with me, and they apologized for the
+necessity that caused them to blindfold me. They said they were
+ready to proceed with the making of diamonds, but I must promise
+not to seek to discover the secret until they gave me permission,
+nor was I to attempt to leave the cave. I had to agree.</p>
+
+<p>&quot;Next they demanded that I give them a large sum, which I had
+promised when they showed me, conclusively, that they could make
+diamonds. I refused to do this until I had seen some of the
+precious stones, and they agreed that this was fair, but said I
+would have to wait a few days.</p>
+
+<p>&quot;Well, I waited, and, all that while, I was virtually a
+prisoner in the cave. All I could learn was that it was in the
+midst of a great range, near the top, and that one of the peaks
+was called Phantom Mountain. Why, I did not learn until later.</p>
+
+<p>&quot;At last one night, during a terrific thunder storm, the
+leader of the diamond makers&mdash;Folwell&mdash;announced that I could now
+see the stones made. The men had been preparing their chemicals
+for some days previous. I was taken into a small chamber of the
+cave, and there saw quite a complicated apparatus. Part of it was
+a great steel box, with a lever on it.</p>
+
+<p>&quot;We will let you make some diamonds for yourself,&quot; Folwell said
+to me, and he directed me to pull the lever of the box, at a
+certain signal. The signal came, just as a terrific crash of
+thunder shook the very mountain inside of which we were. The box
+of steel got red-hot, and when it cooled off it was opened, and
+was given a handful of white stones.&quot;</p>
+
+<p>&quot;Were they diamonds?&quot; asked Tom, eagerly.</p>
+
+<p>Mr. Jenks held out one hand. In the palm glittered a large
+stone&mdash;ostensibly a diamond. In the rays of the moon it showed
+all the colors of the rainbow&mdash;a beautiful gem. &quot;That is one of
+the stones I made&mdash;or rather that I supposed I had made,&quot; went on
+Mr. Jenks. &quot;It is one of several I have, but they have not all
+been cut and polished as has this one.</p>
+
+<p>&quot;Naturally I was much impressed by what I saw, and, after I had
+made certain tests which convinced me that the stones in the
+steel box were diamonds, I paid over the money as I had promised.
+That was my undoing.&quot;</p>
+
+<p>&quot;How?&quot;</p>
+
+<p>&quot;As soon as the men got the cash, they had no further use for
+me. The next I remember is eating a rude meal, while we discussed
+the future of making diamonds. I knew nothing more until I found
+myself back in the small hotel at Indian Ridge, whence I had gone
+some time previous, with the men, to the cave in the mountain.&quot;</p>
+
+<p>&quot;What happened?&quot; asked Tom, much surprised by the unexpected
+outcome of the affair. &quot;I had been tricked, that was all! As soon
+as the men had my money they had no further use for me. They did
+not want me to learn the secret of their diamond making, and they
+drugged me, carried me away from the cave, and left me in the
+hotel.&quot;</p>
+
+<p>&quot;Didn't you try to find the cave again?&quot;</p>
+
+<p>&quot;I did, but without avail. I spent some time in the Rockies,
+but no one could tell where Phantom Mountain was; in fact, few
+had heard of it, and I was nearly lost searching for it.</p>
+
+<p>&quot;I came back East, determined to get even. I had given the men
+a very large sum of money, and, in exchange, they had given me
+several diamonds. Probably the stones are worth nearly as much as
+the money I invested, but I was cheated, for I was promised an
+equal share in the profits. These were denied me, and I was
+tricked. I determined to be revenged, or at least to discover the
+secret of making diamonds. It is my right.&quot;</p>
+
+<p>&quot;I agree with you,&quot; spoke Tom.</p>
+
+<p>&quot;But, up to the time I met you on Earthquake Island, I could
+form no plan for discovering Phantom Mountain, and learning the
+secret of the diamond makers,&quot; went on Mr. Jenks. &quot;I carried the
+gems about with me, as you doubtless saw when we were on the
+island. But I knew I needed an airship in which to fly over the
+mountains, and pick out the location of the cave where the
+diamonds are made.&quot;</p>
+
+<p>&quot;But how can you locate it, if you were blindfolded when you
+were taken there, Mr. Jenks?&quot;</p>
+
+<p>&quot;I forgot to tell you that, on our journey into the mountains,
+and just before I was carried into the cave, I managed to raise
+one corner of the bandage. I caught a glimpse of a very
+peculiarly shaped cliff&mdash;it is like a great head, standing out in
+bold relief against the moonlight, when I saw it. That head of
+rock is near the cave. It may be the landmark by which we can
+locate Phantom Mountain.&quot;</p>
+
+<p>&quot;Perhaps,&quot; admitted the young inventor.</p>
+
+<p>&quot;What I want to know is this,&quot; went on Mr. Jenks. &quot;Will you go
+with me on this quest&mdash;go in your airship to discover the secret
+of the diamond makers? If you will, I will share with you
+whatever diamonds we can discover, or make; besides paying all
+expenses. Will you go, Tom Swift?&quot;</p>
+
+<p>The young inventor did not know what to answer. How far was Mr.
+Jenks to be trusted? Were the stones he had real diamonds? Was
+his story, fantastical as it sounded&mdash;true? Would it be safe for
+Tom to go?</p>
+
+<p>The lad asked himself these questions. Mr. Jenks saw his
+hesitation.</p>
+
+<p>&quot;Here,&quot; said the strange man, &quot;I will prove what I say. Take
+this diamond. I intended it for you, anyhow, for what you did for
+me on Earthquake Island. Take it, and&mdash;and give it to the person
+for whom you were about to purchase a diamond to-night. But,
+first of all, take it to a gem expert, and get his opinion. That
+will prove the truth of what I say, Tom Swift, and I feel sure
+that you will cast your lot in with mine, and help me to discover
+the secret of Phantom Mountain, and aid me to get my rights from
+the diamond makers!&quot;</p>
+

+
+
+<p>Tom Swift considered a few minutes. On the face of it, the
+proposition appealed to him. He had been home some time now after
+his adventures on Earthquake Island, and he was beginning to long
+for more excitement. The search for the mysterious mountain, and
+the cave of the diamond makers, might offer a new field for him.
+But there came to him a certain distrust of Mr. Jenks.</p>
+
+<p>&quot;I don't like to doubt your word,&quot; began Tom, slowly, &quot;but you
+know, Mr. Jenks, that some of the greatest chemists have tried in
+vain to make diamonds; or, at best, they have made only tiny
+ones. To think that any man, or set of men, made real diamonds as
+large as the ones you have, doesn't seem&mdash;well&mdash;&quot; and Tom
+hesitated.</p>
+
+<p>&quot;You mean you can hardly believe me?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;I guess that's it,&quot; assented Tom.</p>
+
+<p>&quot;I don't blame you a bit!&quot; exclaimed the odd man. &quot;In fact, I
+didn't believe it when they told me they could make diamonds. But
+they proved it to me. I'm ready now to prove it to you.&quot;</p>
+
+<p>&quot;I'll tell you what I'll do. Here's this one stone, cut ready
+for setting. Here's another, uncut,&quot; and Mr. Jenks drew from his
+pocket what looked like a piece of crystal. &quot;Take them to any
+jeweler,&quot; he resumed&mdash;&quot;to the one in whose place I saw you to-night.
+I'll abide by the verdict you get, and I'll come here to-morrow
+night, and hear what you have to say.&quot;</p>
+
+<p>&quot;Why do you come at night?&quot; asked Tom, thinking there was
+something suspicious in that.</p>
+
+<p>&quot;Because my life might be in danger if I was seen talking to
+you, and showing you diamonds in the daytime&mdash;especially just
+now.</p>
+
+<p>&quot;Why at this particular time?&quot;</p>
+
+<p>&quot;For the reason that the diamond makers are on my trail. As
+long as I remained quiet, after their shabby treatment of me, and
+did not try to discover their secret, they were all right. But,
+after I realized that I had been cheated out of my rights, and
+when I began to make an investigation, with a view to discovering
+their secret whereabouts, I received mysterious and anonymous
+warnings to stop.&quot;</p>
+
+<p>&quot;But I did not. I came East, and tried to get help to discover
+the cave of the diamond makers, but I was unsuccessful. I needed
+an airship, as I&mdash;said, and no person who could operate one,
+would agree to go with me on the quest. Again I received a
+warning to drop all search for the diamond makers, but I
+persisted, and about a week ago I found I was being shadowed.&quot;</p>
+
+<p>&quot;Shadowed; by whom?&quot; asked Tom.</p>
+
+<p>&quot;By a man I never remember seeing, but who, I have no doubt, is
+one of the diamond-making gang.&quot;</p>
+
+<p>&quot;Do you think he means you harm?&quot;</p>
+
+<p>&quot;I'm sure of it. That is the reason I have to act so in secret,
+and come to see you at night. I don't want those scoundrels to
+find out what I am about to do. On my return from Earthquake
+Island, I again endeavored to interest an airship man in my plan,
+but he evidently thought me insane. Then I thought of you, as I
+had done before, but I was afraid you, too, would laugh at my
+proposition. However, I decided to come here, and I did. It
+seemed almost providential that my first view of you was in a
+jewelry shop, looking at diamonds. I took it as a good omen. Now
+it remains with you. May I call here to-morrow night, and get
+your answer?&quot;</p>
+
+<p>Tom Swift made up his mind quickly. After all it would be easy
+enough to find out if the diamonds were real. If they were, he
+could then decide whether or not to go with Mr. Jenks on the
+mysterious quest. So he answered:</p>
+
+<p>&quot;I'll consider the matter, Mr. Jenks. I'll meet you here to-morrow
+night. In the meanwhile, for my own satisfaction, I'll let
+an expert look at these stones.&quot;</p>
+
+<p>&quot;Get the greatest diamond expert in the world, and he'll
+pronounce them perfect!&quot; predicted the odd man. &quot;Now I'll bid you
+goodnight, and be going. I'll be here at this time to-morrow.&quot;</p>
+
+<p>As Mr. Jenks turned aside there was a movement among the trees
+in the orchard, and a shadowy figure was seen hurrying away.</p>
+
+<p>&quot;Who's that?&quot; asked the diamond man, in a hoarse whisper. &quot;Did
+you see that, Tom Swift? Some one was here&mdash;listening to what I
+said! Perhaps it was the man who has been shadowing me!&quot;</p>
+
+<p>&quot;I think not. I guess it was Eradicate Sampson, a colored man
+who does work for us,&quot; said Tom. &quot;Is that you, Rad?&quot; he called.</p>
+
+<p>&quot;Yais, sah, Massa Tom, heah I is!&quot; answered the voice of the
+negro, but it came from an entirely different direction than that
+in which the shadowy figure had been seen.</p>
+
+<p>&quot;Where are you, Rad?&quot; called the young inventor.</p>
+
+<p>&quot;Right heah,&quot; was the reply, and the colored man came from the
+direction of the stable. &quot;I were jest out seein' if mah mule
+Boomerang were all right. Sometimes he's restless, an' don't
+sleep laik he oughter.&quot;</p>
+
+<p>&quot;Then that wasn't you over in the orchard?&quot; asked Tom, in some
+uneasiness.</p>
+
+<p>&quot;No, sah, I ain't been in de orchard. I were sleepin' in mah
+shack, till jest a few minutes ago, when I got up, an' went in t'
+see Boomerang. I had a dream dat some coon were tryin t' steal
+him, an' it sort ob 'sturbed me, laik.&quot;</p>
+
+<p>&quot;If it wasn't your man, it was some one else,&quot; said Mr. Jenks,
+decidedly.</p>
+
+<p>&quot;We'll have a look!&quot; exclaimed Tom. &quot;Here, Rad, come over and
+scurry among those trees. We just saw some one sneaking around.&quot;</p>
+
+<p>&quot;I'll sure do dat!&quot; cried the colored man. &quot;Mebby it were
+somebody arter Boomerang! I'll find 'em.&quot;</p>
+
+<p>&quot;I don't believe it was any one after the mule,&quot; murmured Mr.
+Jenks, &quot;but it certainly was some one&mdash;more likely some one after
+me.&quot;</p>
+
+<p>The three made a hasty search among the trees, but the intruder
+had vanished, leaving no trace. They went out into the road,
+which the moon threw into bold relief along its white stretch,
+but there was no figure scurrying away.</p>
+
+<p>&quot;Whoever it was, is gone,&quot; spoke Tom. &quot;You can go back to bed,
+Rad,&quot; for the colored man, of late, had been sleeping in a shack
+on the Swift premises.</p>
+
+<p>&quot;And I guess it's time for me to go, too,&quot; added Mr. Jenks.
+&quot;I'll be here to-morrow night, Tom, and I hope your answer will
+be favorable.&quot;</p>
+
+<p>Tom did not sleep well the remainder of the night, for his
+fitful slumbers were disturbed by dreams of enormous caves,
+filled with diamonds, with dark, shadowy figures trying to put
+him into a red-hot steel box. Once he awakened with a start, and
+put his hand under his pillow to feel if the two stones Mr. Jenks
+had given him, were still there. They had not been disturbed.</p>
+
+<p>Tom made up his mind to find out if the stones were really
+diamonds, before saying anything to his father about the chance
+of going to seek Phantom Mountain. And the young inventor wished
+to get the opinion of some other jeweler than Mr. Track&mdash;at
+least, at first.</p>
+
+<p>&quot;Though if this one proves to be a good gem, I'll have Mr.
+Track set it in a brooch, and give it to Mary for her birthday,&quot;
+decided the young inventor. &quot;Guess I'll take a run over to
+Chester in the Butterfly, and see what one of the jewelers there
+has to say.&quot;</p>
+
+<p>In addition to his big airship, Red Cloud, Tom owned a small,
+swift monoplane, which he called Butterfly. This had been damaged
+by Andy Foger just before Tom left on the trip that ended at
+Earthquake Island, but the monoplane had been repaired, and Andy
+had left town, not having returned since.</p>
+
+<p>Telling his father that he was going off on a little business
+trip, which he often did in his aeroplane, Tom, with the aid of
+Mr. Jackson, the engineer, wheeled the Butterfly out of its shed.</p>
+
+<p>Adjusting the mechanism, and seeing that it was in good shape,
+Tom took his place in one of the two seats, for the monoplane
+would carry two. Mr. Jackson then spun the propellers, and, with
+a crackle and roar the motor started. Over the ground ran the
+dainty, little aeroplane, until, having momentum enough, Tom
+tilted the wing planes and the machine sailed up into the air.</p>
+
+<p>Rising about a thousand feet, and circling about several times
+to test the wind currents, Tom headed his craft toward Chester,
+a city about fifty miles from Shopton. In his pocket, snugly
+tucked away, were the two stones Mr. Jenks had given him.</p>
+
+<p>It was not long before Tom saw, looming up in the distance the
+church spires and towering factory chimneys of Chester, for his
+machine was a speedy one, and could make ninety miles an hour
+when driven. But now a slower speed satisfied our hero.</p>
+
+<p>&quot;I'll just drop down outside of the city,&quot; he reasoned, &quot;for
+too much of a crowd gathers when I land in the street. Besides I
+might frighten horses, and then, too, it's hard to get a good
+start from the street. I'll leave it in some barn until I want to
+go back.&quot;</p>
+
+<p>Tom sent his craft down, in order to pick out a safe place for
+a landing. He was then over the suburbs of the city, and was
+following the line of a straight country road.</p>
+
+<p>&quot;Looks like a good place there,&quot; he murmured. &quot;I'll shut off
+the motor, and vol-plane down.&quot;</p>
+
+<p>Suiting the action to the word, Tom shut off his power. The
+little craft dipped toward the ground, but the lad threw up the
+forward planes, and caught a current of air that sent him
+skimming along horizontally.</p>
+
+<p>As he got nearer to the ground, he saw the figure of a lad
+riding a bicycle along the country highway. Something about the
+figure struck Tom as being familiar, and he recognized the
+cyclist a moment later.</p>
+
+<p>&quot;It's Andy Foger!&quot; said Tom, in a whisper. &quot;I wondered where he
+had been keeping himself since he damaged the Butterfly.
+Evidently he doesn't dare venture back to Shopton. Well, here's
+where I give him a scare.&quot;</p>
+
+<p>Tom's monoplane was making no more noise, now, than a soaring
+bird. He was gliding swiftly toward the earth, and, with the plan
+in his mind of administering some sort of punishment to the
+bully, he aimed the machine directly at him.</p>
+
+<p>Nearer and nearer shot the monoplane, as quietly as a sheet of
+paper might fall. Andy pedaled on, never looking up nor behind
+him, A moment later, as Tom threw up his headplanes, to make his
+landing more easy, and just as he swooped down at one side of the
+cyclist, our hero let out a most alarming yell, right into Andy's
+ear.</p>
+
+<p>&quot;Now I've got you!&quot; he shouted. &quot;I'll teach you to slash my
+aeroplane! Come with me!&quot;</p>
+
+<p>Andy gave one look at the white bird-like apparatus that had
+flown up beside him so noiselessly, and, being too frightened to
+recognize Tom's voice, must have thought that he had been
+overtaken by some supernatural visitor.</p>
+
+<p>Andy gave a yell like an Indian, about to do a stage scalping
+act, and fairly dived over the handlebars of his bicycle,
+sprawling in a heap on the dusty road.</p>
+
+<p>&quot;I guess that will hold you for a while,&quot; observed Tom, grimly,
+as he put on the ground-brake and brought his monoplane to a stop
+not far from the fallen rider.</p>
+

+<h2><a name="CHAPTER_V_A_MYSTERIOUS_MAN" id="CHAPTER_V_A_MYSTERIOUS_MAN" />CHAPTER V&mdash;A MYSTERIOUS MAN</h2>
+
+
+<p>For several minutes Andy Foger did not arise. He remained
+prostrate in the dust, and Tom, observing him, thought perhaps
+the bully might have been seriously injured. But, a little later,
+Andy cautiously raised his head, and inquired in a frightened
+voice:</p>
+
+<p>&quot;Is it&mdash;is it gone?&quot;</p>
+
+<p>&quot;Is what gone?&quot; asked Tom, grimly.</p>
+
+<p>At the sound of his voice, Andy looked up. &quot;Was that you, Tom
+Swift?&quot; he demanded. &quot;Did you knock me off my wheel?&quot;</p>
+
+<p>&quot;My monoplane and I together did,&quot; was the reply; &quot;or, rather,
+we didn't. It was the nervous reaction caused by your fright, and
+the knowledge that you had done wrong, that made you jump over
+the handlebars. That's the scientific explanation.&quot;</p>
+
+<p>&quot;You&mdash;you did it!&quot; stammered Andy, getting to his feet. He
+wasn't hurt much, Tom thought.</p>
+
+<p>&quot;Have it your own way,&quot; resumed our hero. &quot;Did you think it was
+a hob-goblin in a chariot of fire after you, Andy?&quot;</p>
+
+<p>&quot;Huh! Never mind what I thought! I'll have you arrested for
+this!&quot;</p>
+
+<p>&quot;Will you? Delighted, as the boys say. Hop in my airship and
+I'll take you right into town. And when I get you there I'll make
+a charge of malicious mischief against you, for breaking the
+propeller of the Butterfly and slashing her wings. I've mended
+her up, however, so she goes better than ever, and I can take you
+to the police station in jig time. Want to come, Andy?&quot;</p>
+
+<p>This was too much for the bully. He knew that Tom would have a
+clear case against him, and he did not dare answer. Instead he
+shuffled over to where his wheel lay, picked it up, and rode
+slowly off.</p>
+
+<p>&quot;Good riddance,&quot; murmured Tom. He looked about, and saw that he
+was near a house, in the rear of which was a good-sized barn.
+&quot;Guess I'll ask if I can leave the Butterfly there,&quot; he murmured,
+and, ringing the doorbell, he was greeted by a man.</p>
+
+<p>&quot;I'll pay you if you'll let me store my machine in the barn a
+little while, until I go into the city, and return,&quot; spoke the
+lad.</p>
+
+<p>&quot;Indeed, you're welcome to leave it there without pay,&quot; was the
+answer. &quot;I'm interested in airships, and, I'll consider it a
+favor if you'll let me look yours over while it's here.&quot;</p>
+
+<p>Tom readily agreed, and a few minutes later he had caught a
+trolley going into the city. He was soon in one of the largest
+jewelry stores of Chester.</p>
+
+<p>&quot;I'd like to get an expert opinion as to whether or not those
+stones are diamonds,&quot; spoke Tom, to the polite clerk who came up
+to wait on him, and our hero handed over the two gems which Mr.
+Jenks had given him. &quot;I'm willing to pay for the appraisement, of
+course,&quot; the young inventor added, as he saw the clerk looking
+rather doubtfully at him, for Tom had on a rough suit, which he
+always donned when he flew in his monoplane.</p>
+
+<p>&quot;I'll turn them over to our Mr. Porter, a gem expert,&quot; said the
+clerk. &quot;Please be seated.&quot;</p>
+
+<p>The young man disappeared into a private office with the
+stones, and Tom waited. He wondered if he was going to have his
+trouble for his pains. Presently two elderly gentlemen came from
+the little room, on the glass door of which appeared the word
+&quot;Diamonds.&quot;</p>
+
+<p>&quot;Who brought these stones in?&quot; asked one of the men, evidently
+the proprietor, from the deference paid him by the clerk. The
+latter motioned to Tom.</p>
+
+<p>&quot;Will you kindly step inside here?&quot; requested the elderly man.
+When the door was closed, Tom found himself in a room which was
+mostly taken up with a bench for the display of precious stones,
+a few chairs, and some lights arranged peculiarly; while various
+scales and instruments stood on a table.</p>
+
+<p>&quot;You wished an opinion on&mdash;on these?&quot; queried the proprietor of
+the place. Tom noticed at once that the word &quot;diamonds&quot; was not
+used.</p>
+
+<p>&quot;I wanted to find out if they were of any value,&quot; he said. &quot;Are
+they diamonds?&quot;</p>
+
+<p>&quot;Would you mind stating where you got them?&quot; asked the other of
+the two men.</p>
+
+<p>&quot;Is that necessary?&quot; inquired the lad. &quot;I came by them in a
+legitimate manner, if that's what you mean, and I can satisfy you
+on that point. I am willing to pay for any information you may
+give me as to their value.&quot;</p>
+
+<p>&quot;Oh, it isn't that,&quot; the proprietor hastened to assure him.
+&quot;But these are diamonds of such a peculiar kind, so perfect and
+without a flaw, that I wondered from what part of the world they
+came.&quot;</p>
+
+<p>&quot;Then they are diamonds?&quot; asked Tom, eagerly.</p>
+
+<p>&quot;The finest I have ever tested!&quot; declared the other man,
+evidently Mr. Porter, the gem expert. &quot;They are a joy to look at,
+Mr. Roberts,&quot; he went on, turning to the proprietor. &quot;If it is
+possible to get a supply of them you would be justified in asking
+half as much again as we charge for African or Indian diamonds.
+The Kimberly products are not to be compared to these,&quot; and he
+looked at the two stones in his hand&mdash;the one cut, and sparkling
+brilliantly, the other in a rough state.</p>
+
+<p>&quot;Do you care to state where these diamonds came from?&quot; asked
+Mr. Roberts, looking critically at Tom.</p>
+
+<p>&quot;I had rather not,&quot; answered the lad. &quot;It is enough for me to
+know that they are diamonds. How much is your charge?&quot;</p>
+
+<p>&quot;Nothing,&quot; was the unexpected answer. &quot;We are very glad to have
+had the opportunity of seeing such stones. Is there any chance of
+getting any more?&quot;</p>
+
+<p>&quot;Perhaps,&quot; answered Tom, as he accepted the gems which the
+expert held out to him.</p>
+
+<p>&quot;Then might we speak for a supply?&quot; went on Mr. Roberts,
+eagerly. &quot;We will pay you the full market price.&quot;</p>
+
+<p>&quot;What is the value of these stones?&quot; asked Tom.</p>
+
+<p>Mr. Roberts looked at his gem expert.</p>
+
+<p>&quot;It is difficult to say,&quot; was the answer of the man who had
+handed Tom the gems. &quot;They are so far superior to the usual run
+of diamonds, that I feel justified in saying that the cut one
+would bring fifteen hundred dollars, anywhere. In fact, I would
+offer that for it. The other is larger, though what it would lose
+in cutting would be hard to say. I should say it was worth two
+thousand dollars as it is now.&quot;</p>
+
+<p>&quot;Thirty-five hundred dollars for these two stones!&quot; exclaimed
+Tom.</p>
+
+<p>&quot;They are worth every cent of it,&quot; declared Mr. Roberts. &quot;Do
+you want to sell?&quot;</p>
+
+<p>Tom shook his head. He could scarcely believe the good news.
+Mr. Jenks had told the truth. Now the young inventor could go
+with him to seek the diamond makers.</p>
+
+<p>&quot;Can you get any more of these?&quot; went on Mr. Roberts.</p>
+
+<p>&quot;I think so&mdash;that is I don't know&mdash;I am going to try,&quot; answered
+the lad.</p>
+
+<p>&quot;Then if you succeed I wish you would sell us some,&quot; fairly
+begged the proprietor of the store.</p>
+
+<p>&quot;I will,&quot; promised Tom, but he little knew what lay before him,
+or perhaps he would not have made that promise. He thanked the
+diamond merchant for his kindness, and arranged to have the cut
+stone set in a pin for Miss Nestor. The uncut gem Tom took away
+with him.</p>
+
+<p>Thinking of many things, and wondering how best to start in his
+airship Red Cloud for the mysterious Phantom Mountain, Tom
+hurried back to where he had left the monoplane, wheeled it out,
+and was soon soaring through the air toward Shopton.</p>
+
+<p>&quot;I think I'll go with Mr. Jenks,&quot; he decided, as he prepared
+for a landing in the open space near his aeroplane shed. &quot;It will
+be a risky trip, perhaps, but I've taken risks before. When Mr.
+Jenks comes to-night I'll tell him I'll help him to get his
+rights, and discover the secret of the diamond makers.&quot;</p>
+
+<p>As Tom was wheeling the Butterfly into the shed, Eradicate came
+out to help him.</p>
+
+<p>&quot;Dere's a gen'man here to see yo', Massa Tom,&quot; said the colored
+man.</p>
+
+<p>&quot;Who is it?&quot;</p>
+
+<p>&quot;I dunno. He keep askin' ef yo' de lad what done bust up
+Earthquake Island, an' send lightnin' flashes up to de sky, an'
+all sech questions laik dat.&quot;</p>
+
+<p>&quot;It isn't Mr. Damon; is it, Rad? He hasn't been around in some
+time.&quot;</p>
+
+<p>&quot;No, Massa Tom, it ain't him. I knows dat blessin' man good an'
+proper. I jest wish he'd bless mah mule Boomerang some day, an'
+take some oh de temper out ob him. No, sah, it ain't Massa Damon.
+De gen'man's in de airship shed waitin' fo' you.&quot;</p>
+
+<p>&quot;In the airship shed! No strangers are allowed in there, Rad.&quot;</p>
+
+<p>&quot;I knows it, Massa Tom, but he done persisted his se'f inter
+it, an' he wouldn't come out when I told him; an' your pa an' Mr.
+Jackson ain't home.&quot;</p>
+
+<p>&quot;I'll see about this,&quot; exclaimed Tom, striding to the large
+shed, where the Red Cloud was kept. As he entered it he saw a man
+looking over the wonderful craft.</p>
+
+<p>&quot;Did you want to see me?&quot; asked Tom, sharply, for he did not
+like strangers prowling around.</p>
+
+<p>&quot;I did, and I apologize for entering here, but I am interested
+in airships, and I thought you might want to hire a pilot. I am
+in need of employment, and I have had considerable to do with
+balloons and aeroplanes, but never with an airship like this,
+which combines the two features. Do you wish to hire any one.&quot;</p>
+
+<p>&quot;No, I don't!&quot; replied Tom, sharply, for he did not like the
+looks of the man.</p>
+
+<p>&quot;I was told that you did,&quot; was the rather surprising answer.</p>
+
+<p>&quot;Who told you?&quot;</p>
+
+<p>The man looked all around the shed, before replying, as if
+fearful of being overheard. Then, stepping close to Tom, he
+whispered:</p>
+
+<p>&quot;Mr. Jenks told me!&quot;</p>
+
+<p>&quot;Mr. Jenks?&quot; Tom could not conceal his astonishment.</p>
+
+<p>&quot;Yes. Mr. Barcoe Jenks. But I did not come here to merely ask
+you for employment. I would like to hire out to you, but the real
+object of my visit was to say this to you.&quot;</p>
+
+<p>The man approached still closer to Tom, and, in a lower voice,
+and one that could scarcely be heard, he fairly hissed:</p>
+
+<p>&quot;Don't go with Barcoe Jenks to seek the diamond makers!&quot;</p>
+
+<p>Then, before Tom could put out a hand to detain him, had the
+lad so wished, the man turned suddenly, and fairly ran from the
+shed.</p>

+<h2><a name="CHAPTER_VI_MR_DAMON_IS_ON_HAND" id="CHAPTER_VI_MR_DAMON_IS_ON_HAND" />CHAPTER VI-MR. DAMON IS ON HAND</h2>
+
+
+<p>The young inventor stood almost spellbound for a few moments.
+Then recovering himself he made a dash for the door through which
+the mysterious man had disappeared. Tom saw him sprinting down
+the road, and was half-minded to take after him, but a cooler
+thought warned him that he had better not.</p>
+
+<p>&quot;He may be one of those men who are on Mr. Jenks' trail,&quot;
+reasoned Tom, in which case it might not be altogether safe to
+attempt to stop him, and make him explain. Or he may be a
+lunatic, and in that case it wouldn't be altogether healthy to
+interfere with him.</p>
+
+<p>&quot;I'll just let him go, and tell Mr. Jenks about him when he
+comes to-night. But I must warn Rad never to let him in here
+again. He might damage the airship.&quot;</p>
+
+<p>Calling to the colored man, Tom pointed to the stranger, who
+was almost out of sight down the road, and said earnestly:</p>
+
+<p>&quot;Rad, do you see that fellow?&quot;</p>
+
+<p>&quot;I sho do, Massa Tom, but I sorter has t' strain my eyes t' do
+it. He's goin' laik my mule Boomerang does when he's comm' home
+t' dinnah.&quot;</p>
+
+<p>&quot;That's right, Rad. Well, never let that man set foot inside
+our fence again! If he comes, and I'm home, call me. If I'm away,
+call dad or Mr. Jackson, and if you're here alone, drive him
+away, somehow.&quot;</p>
+
+<p>&quot;I will, Massa Tom!&quot; exclaimed the colored man, earnestly, &quot;an'
+if I can't do it alone, I'll get Boomerang t' help. Once let dat
+ar' mule git his heels on a pusson, an' dat pusson ain't goin' t'
+come bodderin' around any mo'&mdash;that is, not right away.&quot;</p>
+
+<p>&quot;I believe you, Rad. Well, keep a lookout for him, and don't
+let him in,&quot; and with that Tom entered the house to think over
+matters. They were beginning to assume an aspect he did not
+altogether like. Not that Tom was afraid of danger, but he
+preferred to meet it in the open, and the warning, or threat, of
+the mysterious man disquieted him.</p>
+
+<p>When Mr. Swift came home, a little later, his son told him of
+the midnight interview with Mr. Jenks, for, up to this time, the
+aged inventor was unaware of it, and Tom also gave an account of
+the diamonds, speaking of their value.</p>
+
+<p>&quot;And do you propose to go to Phantom Mountain, in search of the
+makers of these gems, Tom?&quot; asked Mr. Swift.</p>
+
+<p>&quot;I had about decided to do so, dad.&quot;</p>
+
+<p>&quot;And you're going in the Red Cloud?'</p>
+
+<p>&quot;Yes.&quot;</p>
+
+<p>&quot;Who are going with you?&quot;</p>
+
+<p>&quot;Well, Mr. Jenks will go, of course, and I've no doubt but that
+if I mention the prospective trip to Mr. Damon, that he'll bless
+his skating cap, or something like that, and come along.&quot;</p>
+
+<p>&quot;I suppose so, Tom, and I'd like to have you take him. But I
+think you'll need some one else.&quot;</p>
+
+<p>&quot;Because, from what you have told me, you are going out to a
+dangerous part of the country, and you may have to deal with
+unscrupulous men. Three of you are hardly enough to cope with
+them. You ought to have at least another member of your party. If
+I was not busy on my invention of a new wireless motor I would go
+along, but I can't leave. You might take Mr. Jackson.&quot;</p>
+
+<p>&quot;No, you need him here to help you, dad.&quot;</p>
+
+<p>&quot;How about Eradicate?&quot;</p>
+
+<p>Tom smiled.</p>
+
+<p>&quot;Rad would get homesick for his mule Boomerang, and I'd have to
+bring him back just when we'd found the diamonds,&quot; replied the
+young inventor. &quot;No, we'll have to think of some one else. I'll
+ask Mr. Damon, and then I'll consider matters further. I expect
+to see Mr. Jenks to-night, and he may have some one in mind.&quot;</p>
+
+<p>&quot;Perhaps that will be a good plan. Well, Tom, I trust you will
+take good care of yourself, and not run into unnecessary danger.
+Is the Red Cloud in good shape for the voyage?&quot;</p>
+
+<p>&quot;It needs looking over. I'm going to get right at it.&quot;</p>
+
+<p>&quot;It's a pretty indefinite sort of a quest you're going on, Tom,
+my son. How do you expect to find Phantom Mountain?&quot;</p>
+
+<p>&quot;Well, it's going to be quite a task. In the first place we'll
+head for Leadville, Colorado, and then we'll go to Indian Ridge
+and make some inquiries. We may get on the track of the place
+that way. If we don't, why I'll take the airship up as high as is
+necessary and sort of prospect until we see that big cliff that's
+shaped like a head. That will give us something to go by.&quot;</p>
+
+<p>&quot;Well, do the best you can. If you can discover the secret of
+making diamonds it will be a valuable one.&quot;</p>
+
+<p>&quot;I guess it will, dad; and Mr. Jenks is entitled to know it,
+for he paid his good money to that end. He has promised to go
+halves with me, as payment for the use of the airship, and I must
+say the two diamonds he gave me last night have proved very
+valuable.&quot;</p>
+
+<p>&quot;Two diamonds, Tom? You only showed me one, an uncut gem&quot;; and
+Mr. Swift looked at his son.</p>
+
+<p>&quot;Oh, the other&mdash;er&mdash;the other is&mdash;I left it with a jeweler,&quot;
+and Tom blushed a trifle, as he thought of the present he
+contemplated making to Mary Nestor.</p>
+
+<p>That afternoon, as Tom was out in the shed of the Red Cloud
+looking over the airship, to see what would be necessary to do to
+it in order to get it in shape for a long trip, he heard voices
+outside.</p>
+
+<p>&quot;Yes&mdash;yes, I know the way in perfectly well,&quot; he caught. &quot;You
+needn't bother to come, my good fellow. Just step this way, and
+I'll show you something worth seeing.&quot;</p>
+
+<p>&quot;I wonder if it's that mysterious man coming back?&quot; thought
+Tom. He dropped the tool he was using, and hurried to the door.
+As he approached it he heard the voice continue.</p>
+
+<p>&quot;Why bless my shoe laces, Mr. Parker! You'll see a wonderful
+airship, I promise you. Wonderful! Bless my hatband, but I hope
+Tom is here!&quot;</p>
+
+<p>&quot;Mr. Damon!&quot; exclaimed our hero, as he recognized the tones of
+his eccentric friend. &quot;But who is with him?&quot;</p>
+
+<p>A moment later he caught sight of the gentleman who was always
+blessing himself, or something. Behind him stood another man,
+whose features Tom could not see plainly.</p>
+
+<p>&quot;Hello, Tom Swift!&quot; called Mr. Damon. &quot;Looking over the Red
+Cloud, eh? Does that mean you're off on another trip?&quot;</p>
+
+<p>&quot;I guess it does,&quot; answered the lad.</p>
+
+<p>&quot;Where to this time? if I may ask.&quot;</p>
+
+<p>&quot;I'm thinking of going off to the mountains to find a band of
+men engaged in making diamonds,&quot; replied Tom.</p>
+
+<p>&quot;Making diamonds! Bless my finger ring! Making diamonds! A trip
+to the mountains! Bless my disposition! but do you know I'd like
+to go with you!&quot;</p>
+
+<p>&quot;I was thinking of asking you, Mr. Damon.&quot;</p>
+
+<p>&quot;Were you? Bless my heart, I'm glad you thought of me. You
+don't by any possible chance want another person; do you?&quot;</p>
+
+<p>&quot;We were thinking of having four in the party, Mr. Damon,&quot; and
+Tom wondered who was with his eccentric friend.</p>
+
+<p>&quot;Then bless my election ticket! This is the very chance for
+you, Mr. Parker!&quot; cried Mr. Damon. &quot;Will you go with us? It will
+be just what you need,&quot; and Mr. Damon stepped aside, revealing to
+Tom the features of Mr. Ralph Parker, the scientist who had
+correctly predicted the destruction of Earthquake Island.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_VII_MR_PARKER_PREDICTS" id="CHAPTER_VII_MR_PARKER_PREDICTS" />CHAPTER VII&mdash;MR. PARKER PREDICTS</h2>
+
+
+<p>Tom Swift was a most generous lad, but when he saw that Mr.
+Damon had with him Mr. Parker, the gloomy scientist, who seemed
+to take delight in predicting disasters, our hero's spirits were
+not exactly of the best. He would have much preferred not to take
+Mr. Parker on the quest for the diamond makers, but, since Mr.
+Damon had mentioned it, he did not see how he could very well
+refuse.</p>
+
+<p>&quot;But perhaps he won't care to go,&quot; thought Tom.</p>
+
+<p>He was undeceived a moment later, however, for the scientist
+remarked:</p>
+
+<p>I am very glad to meet you once more, Mr. Swift. I have
+scarcely thanked you enough for what you did for us in erecting
+your wireless station on Earthquake Island, which, as you recall,
+I predicted would sink into the sea. It did, I am glad to say,
+not because I like to see islands destroyed, but because science
+has been vindicated. Now I have just heard you remark that you
+are about to set off to the mountains in search of some men who
+are making diamonds. I need hardly state that this is utterly
+useless, for no diamonds, commercially valuable, can be made by
+men. But the trip may be valuable in that it will permit me to
+demonstrate some scientific facts.</p>
+
+<p>&quot;Therefore, if you will permit me, I will be very glad to
+accompany you and Mr. Damon. I shall be delighted, in short, and
+I can start as soon as you are ready.&quot;</p>
+
+<p>&quot;There's no hope for it!&quot; thought Tom, dismally. &quot;I suppose
+he'll wake up every morning, and predict that before night the
+world will come to an end, or he'll prophesy that the airship
+will blow up, and vanish, when about seven miles above the
+clouds. Well, there's no way out of it, so here goes.&quot;</p>
+
+<p>Thereupon Tom welcomed the scientist as cordially as he could,
+and invited him to form one of the party that would set off in
+the airship to search for Phantom Mountain.</p>
+
+<p>&quot;Bless my jewelry box!&quot; exclaimed Mr. Damon, when this
+formality was over. &quot;Tell me more about it, Tom.&quot;</p>
+
+<p>Which our hero did, stating the need of maintaining secrecy on
+account of the danger to Mr. Jenks. Mr. Damon and Mr. Parker both
+agreed to say nothing about the matter, and then the scientist
+became much interested in the Red Cloud, which he closely
+examined. He even complimented Tom on the skill shown in making
+it, and, contrary to our hero's expectation, did not predict that
+it would blow up the next time it was used.</p>
+
+<p>&quot;How did you happen to arrive just at this time, Mr. Damon?&quot;
+asked Tom.</p>
+
+<p>&quot;It was partly due to Mr. Parker,&quot; was the answer. &quot;I had not
+seen him since we were rescued from the island, until a few days
+ago he called on me at my home. I happened to mention that you
+lived near here, and suggested that he might like to see some of
+your inventions. He agreed, and we came over in my auto. And now,
+bless my liver-pin! I find you about to start off on another
+trip.&quot;</p>
+
+<p>&quot;And have you fully decided to go with me?&quot; asked Tom. &quot;There
+may be danger, and I don't like the way that mysterious man
+behaved.&quot;</p>
+
+<p>&quot;Oh, bless my revolver!&quot; cried Mr. Damon. &quot;I'm used to danger
+by this time. Of course I'm going, and so is Mr. Parker. Do you
+know,&quot; and the man, who was always blessing something, came
+closer to the lad, and whispered: &quot;Do you know, Tom, Mr. Parker
+is a very peculiar individual.&quot;</p>
+
+<p>&quot;I'm sure of it,&quot; answered the young inventor, looking at the
+gentleman in question, who was then inside the airship cabin.</p>
+
+<p>&quot;But he's all right, even if he is predicting unpleasant
+things,&quot; went on Mr. Damon. &quot;I think we'll get better acquainted
+with him after a bit.&quot;</p>
+
+<p>&quot;I hope so,&quot; agreed Tom, but he did not realize then how close
+his companionship with Mr. Parker was to be, nor what dangers
+they were to share later.</p>
+
+<p>The friends talked at considerable length of the prospective
+trip, and Tom, by this time, had ascertained what needed to be
+done to the airship to get it in shape to travel. It would take
+about a week, and, in the meanwhile, Mr. Damon would go home and
+get his affairs in order for the voyage. Tom's father was
+introduced to Mr. Parker, and, the former, finding that the
+scientist held some views in common with him, invited the gloomy
+predictor to remain at the Swift home until the Red Cloud was
+ready to sail. Tom could not repress a groan at this, but he
+decided he would have to make the best of it.</p>
+
+<p>Mr. Damon left for home that afternoon, promising to be on hand
+at the time set to start for Phantom Mountain.</p>
+
+<p>Tom was up waiting for Mr. Jenks at twelve o'clock that night.
+Shortly after the hour he saw a dark figure steal into the
+orchard. At first he feared lest it might be one of the spies who
+were, he was now convinced, on the trail of the man who was
+seeking to discover the secret of the diamond makers. But a
+whistle, which came to the lad's ear a moment later (that being a
+signal Mr. Jenks had agreed to sound), told Tom that it was none
+other than the visitor he expected.</p>
+
+<p>&quot;All right, Mr. Jenks, I'm here,&quot; called Tom, cautiously. &quot;Come
+over this way,&quot; and he went out from the shadow of the house,
+where he had been waiting, and met the men. &quot;We'll go into my
+private work-shop,&quot; the youth added, leading the way.</p>
+
+<p>&quot;Have you decided to go with me?&quot; asked Mr. Jenks, in an
+anxious whisper. &quot;Did you find the diamonds to be real ones?&quot;</p>
+
+<p>&quot;I did; and I'm going,&quot; spoke Tom.</p>
+
+<p>&quot;Good! That relieves my mind. But we are still in danger. I was
+followed by my shadower to-day, and only succeeded in shaking him
+off just before coming here. I don't believe he knows what I am
+about to do.&quot;</p>
+
+<p>&quot;Oh, yes he does,&quot; said Tom.</p>
+
+<p>&quot;He does? How?&quot;</p>
+
+<p>&quot;Because he was here, and warned me against you!&quot;</p>
+
+<p>&quot;You don't mean it! Well, they are getting desperate! We must
+be on our guard. What sort of a man was he?&quot;</p>
+
+<p>Tom described the fellow, and Mr. Jenks stated that this
+tallied with the appearance of the person who had been shadowing
+him.</p>
+
+<p>&quot;But we'll fool them yet!&quot; cried Tom, who had now fully entered
+into the spirit of the affair. &quot;If they can follow us in the Red
+Cloud they're welcome to. I think we'll get ahead of them.&quot;</p>
+
+<p>He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed
+that it would add to the strength of the party to take these two
+gentlemen along.</p>
+
+<p>&quot;Though I can't say I care so much for Mr. Parker,&quot; he added.
+&quot;But now as to ways and means. When can we start?&quot;</p>
+
+<p>Thereupon he and Tom talked over details in the seclusion of
+the little office, and arranged to leave Shopton in about a week.
+In the meanwhile the airship would be overhauled, stocked with
+supplies and provisions, and be made ready for a swift dash to
+the mountains.</p>
+
+<p>&quot;And now I must be going,&quot; said Mr. Jenks. &quot;I have a great deal
+to do before I can start on this trip, and I hope I am not
+prevented by any of those men who seem to be trailing me.&quot;</p>
+
+<p>&quot;How could they prevent you?&quot; Tom wanted to know.</p>
+
+<p>&quot;Oh, there are any number of ways,&quot; was the answer. &quot;But I'm
+glad you found that my diamonds were real. We'll soon have
+plenty, if all goes well.&quot;</p>
+
+<p>As Mr. Jenks left the shop, he started back, in some alarm.</p>
+
+<p>&quot;What's the matter?&quot; asked Tom.</p>
+
+<p>&quot;Over there&mdash;I thought I saw a figure sneaking along under the
+trees&mdash;that man&mdash;perhaps&mdash;&quot;</p>
+
+<p>&quot;That's Eradicate, our colored helper,&quot; replied Tom, with a
+laugh. &quot;I posted him there to see that no strangers came into the
+orchard. Everything all right, Rad?&quot; he asked, raising his voice.</p>
+
+<p>&quot;Yais, sah, Massa Tom. Nobody been around yeah this night.&quot;</p>
+
+<p>&quot;That's good. You can go to bed now,&quot; and Eradicate, yawning
+loudly, went to his shack. A little later Tom sought his own
+room, Mr. Jenks having hurried off to town, where he was
+boarding.</p>
+
+<p>The next few days saw Tom busily engaged on the airship, making
+some changes and a few repairs that were needed. His father,
+Eradicate and Mr. Jackson helped him. As for Mr. Parker, the
+scientist, he went about the place, being much interested in the
+various machines which Tom or Mr. Swift had patented.</p>
+
+<p>At other times the scientist would stroll about the extensive
+grounds, making what he said were &quot;observations.&quot; One afternoon
+Tom saw him, apparently much excited, kneeling down back of a
+shed, with his ear to the ground.</p>
+
+<p>&quot;What is the matter?&quot; asked the lad, thinking perhaps Mr.
+Parker might be ill.</p>
+
+<p>&quot;Have you ever had any earthquakes here, Tom Swift?&quot; asked the
+scientist, quietly.</p>
+
+<p>&quot;Earthquakes? No. We had enough of them on the island.&quot;</p>
+
+<p>&quot;And you are going to have one here, in about two minutes!&quot;
+cried Mr. Parker. &quot;I predict that this place will be shaken by a
+tremendous shock very soon. We had all better get away from the
+vicinity of buildings.&quot;</p>
+
+<p>&quot;What makes you think there will be an earthquake?&quot; asked Tom.</p>
+
+<p>&quot;Because I can hear the rumbling beneath the ground at this
+very minute. It is increasing in volume, showing that the tremors
+are working this way. There will soon be a great subterranean
+upheaval! Listen for yourself.&quot;</p>
+
+<p>Tom cast himself down on the grass. Placing his ear close to
+the ground he did hear a series of dull thuds. He arose, not a
+little alarmed. There had never been any earthquakes in Shopton,
+yet he had great respect for Mr. Parker's scientific attainments.</p>
+
+<p>Just then Eradicate Sampson came along. He saw Tom and Mr.
+Parker lying flat on the ground, and surprise showed on his
+honest, black face.</p>
+
+<p>&quot;Fo' de land sakes!&quot; cried Eradicate. &quot;What am de mattah now,
+Massa Tom?&quot;</p>
+
+<p>&quot;Earthquake coming,&quot; answered Tom, briefly. &quot;Better get away
+from the buildings, Rad. They might fall!&quot; Tom's face showed the
+alarm he felt. What would happen to all of his valuable
+machines&mdash;to the Red Cloud?</p>
+
+<p>&quot;Earthquake?&quot; murmured Eradicate, and he, too, cast himself
+down to listen. A moment later he arose with a laugh.</p>
+
+<p>&quot;What's the matter?&quot; cried Tom.</p>
+
+<p>&quot;Why, dat ain't no earthquake!&quot; declared the colored man.</p>
+
+<p>&quot;No. Then perhaps you know what it is,&quot; said Mr. Parker,
+somewhat sharply.</p>
+
+<p>&quot;Course I knows what it am,&quot; answered Eradicate, with dignity.
+&quot;Dat noise am my mule Boomerang, kickin' in his stable, on
+account oh me not feedin' him yet. Dat's what it am. I'se gwine
+right now t' gib him his oats, and den yo' see dat de noise stop.
+Boomerang allers kick dat way when he's hungry. I show yo'!&quot;</p>
+
+<p>And, sure enough, when Eradicate had gone to the mule's stable,
+which was near where Mr. Parker had heard the mysterious sounds,
+they immediately ceased.</p>
+
+<p>&quot;Dat mule was all de earthquake dere was around here,&quot; said the
+colored man as he came out.</p>
+
+<p>Mr. Parker walked away, saying nothing, and Tom did not make
+any comments&mdash;just then.</p>
+
+
+

+
+
+<p>It was a great relief to Tom, to find that there was no danger
+from an earth tremor. Now that he had made up his mind to go in
+search of the diamond makers, he wanted nothing to interfere with
+it. Lest the feelings of Mr. Parker might be hurt by the mistake
+he had made, the young inventor cautioned Eradicate not to say
+anything more about the matter.</p>
+
+<p>&quot;'Deed an' I won't,&quot; the colored man promised. &quot;I'se only too
+glad dere wa'n't no earthquake, dat's what I is.&quot;</p>
+
+<p>As for Mr. Parker, he did not appear much put out by his error
+in predicting.</p>
+
+<p>&quot;I am sure that what I heard was a tremor, due to some distant
+earthquake shock,&quot; he said. &quot;The mule's kicking was only a
+coincidence.&quot;</p>
+
+<p>And Tom let him have his way about it. The week was drawing to
+a close, and the Red Cloud was nearly in shape for the voyage. At
+almost the last minute Tom found that he needed some electrical
+apparatus for the airship, and as he had to go to Chester for it,
+he decided he would make the trip in his monoplane, and, while in
+the city, would also get the diamond pin he was having made for
+Mary Nestor.</p>
+
+<p>He started off early one morning, in the swift little craft
+Butterfly, and soon had reached Chester. The diamond brooch was
+ready for him.</p>
+
+<p>&quot;It is one of the most beautiful stones we have ever set,&quot; the
+diamond merchant told him. &quot;Don't forget, if you find any more,
+Mr. Swift, to let us have a chance to bid on them.&quot;</p>
+
+<p>&quot;I may,&quot; Tom promised, rather indefinitely. Then, having
+purchased his electrical supplies, he made a quick trip to
+Shopton, stopping on the way to call on Miss Nestor.</p>
+
+<p>&quot;Why Tom, I'm delighted to see you!&quot; cried the girl, blushing
+prettily. &quot;Did you come for some apple turnovers?&quot; and she
+laughed, as she referred to a call Tom had once paid, when a new
+cook had been engaged, and when the pastry formed a feature of
+the meal.</p>
+
+<p>&quot;No turnovers this time,&quot; said the young inventor. &quot;I came to
+wish you many happy returns of the day.&quot;</p>
+
+<p>&quot;Oh, you remembered my birthday! How nice of you!&quot;</p>
+
+<p>&quot;And here is something else,&quot; added our hero, rather awkwardly,
+as he handed her the diamond pin.</p>
+
+<p>&quot;Oh, Tom! This for me! Oh, it's too lovely&mdash;it's far too much!&quot;</p>
+
+<p>&quot;It isn't half enough!&quot; he declared, warmly. &quot;Oh, what a large
+diamond!&quot; Mary cried as she saw the sparkling stone. &quot;I never saw
+one so large and beautiful!&quot;</p>
+
+<p>&quot;It's just as easy to make them large as small,&quot; explained Tom.</p>
+
+<p>&quot;Make them?&quot; she looked the surprise she felt.</p>
+
+<p>&quot;Yes, I'm about to start for the place where diamonds are
+made.&quot;</p>
+
+<p>&quot;Oh, Tom! But isn't it dangerous? I mean won't you have to go
+to some far country&mdash;like Africa&mdash;to get to where diamonds are
+made?&quot;</p>
+
+<p>&quot;Well, we are going on quite a trip, but not as far as that.
+And as for the danger&mdash;well, we'll have to take what comes,&quot; and
+he told her something of the proposed quest.</p>
+
+<p>&quot;Oh, it sounds&mdash;sounds scary!&quot; Mary exclaimed, when she had
+heard of Mr. Jenks' experience. Do be careful, Tom!&quot;</p>
+
+<p>&quot;I will,&quot; he promised, and, somehow he was glad that she had
+cautioned him thus&mdash;and in such tones as she had used. For Mary
+Nestor was a girl that any young chap would have been glad to
+have manifest an interest in him.</p>
+
+<p>&quot;Well, I guess I'll have to say good-by,&quot; spoke Tom, at length.
+&quot;We expect to start in a couple of days, and I may not get
+another chance to see you.&quot;</p>
+
+<p>&quot;Oh, I&mdash;I hope you come back safely,&quot; faltered Mary, and then
+she held out her hand, and Tom&mdash;well, it's none of our affair
+what Tom did after that, except to say that he hurried out,
+fairly jumped into his monoplane, and completed the trip home.</p>
+
+<p>As the Red Cloud has been fully described in the volume
+entitled &quot;Tom Swift and His Airship,&quot; we will not go into details
+about it now. Sufficient to say that it was a combination of a
+biplane and dirigible balloon. It could be used either as one or
+the other, and the gas-bag feature was of value when the wind was
+too great to allow the use of the planes, or when the motive
+power, for some reason stopped. In that event the airship could
+remain suspended far above the clouds if necessary. There was
+provision for manufacturing the gas on board.</p>
+
+<p>The Red Cloud was fitted up to accommodate about ten persons,
+though it was seldom that this number was carried. Two persons
+could successfully operate the machinery. There were sleeping
+berths, and in the main cabin a sitting-room, a dining-room, and
+a kitchen. There was also the motor compartment, and a steering
+tower, from which the engines could be controlled.</p>
+
+<p>It was in this craft that the seekers after the diamond makers
+proposed undertaking the trip. Mr. Damon came on from his home in
+Waterfield about two days before the date set to leave, and Mr.
+Jenks, had, three days before this, taken up his abode at the
+Swift home. Mr. Parker, as has been stated, was already there,
+and he had put in his time making a number of scientific
+observations, though he had made no more predictions.</p>
+
+<p>Nothing more had been seen of the mysterious man who had warned
+Tom, and the young inventor and Mr. Jenks began to hope that they
+had thrown their enemies off the track.</p>
+
+<p>&quot;Though I don't imagine they'll give up altogether,&quot; said Mr.
+Jenks. &quot;They're too desperate for that. We'll have trouble with
+them yet.&quot;</p>
+
+<p>&quot;Well, it can't be helped,&quot; decided Tom. &quot;We'll try and be
+ready for it, when it comes,&quot; and then, dismissing the matter
+from his mind, he busied himself about the airship.</p>
+
+<p>The food and supplies had all been put aboard, and they
+expected to start the next morning. In order to make sure that
+any stones which they might succeed in getting from the diamond
+makers were real gems, a set of testing apparatus was taken
+along. Mr. Parker had had some experience in this line, and, in
+spite of the fact that he might make direful predictions, Tom was
+rather glad, after all, that the scientist was going to accompany
+them.</p>
+
+<p>&quot;But what is worrying me,&quot; said Mr. Damon, &quot;is what we are
+going to do after we get to Phantom Mountain. What are your
+plans, Mr. Jenks? Will you go in, and demand your share of the
+diamond-making business?&quot;</p>
+
+<p>&quot;I have a right to it, as I invested a large sum in it, and I
+am entitled to more than a half-share. But, of course, I can't
+say what I'll do until I get there. We may have to act very
+secretly.&quot;</p>
+
+<p>&quot;I'm inclined to think we will,&quot; said Tom. &quot;My plan would be to
+gain access to the cave, if possible, and watch them at work. We
+might be able to discover the secret of making diamonds, and,
+after all, that's what you want, isn't it, Mr. Jenks?&quot;</p>
+
+<p>&quot;Yes, I paid my money for the secret, and I ought to have it.
+If I can get it quietly, so much the better. If not, I'll fight
+for my rights!&quot; and he looked very determined.</p>
+
+<p>&quot;Bless my powder horn!&quot; cried Mr. Damon. &quot;That's the way to
+talk! And so we're to go cruising about in the air, looking for a
+mountain shaped like a man's head.&quot;</p>
+
+<p>&quot;That's it,&quot; a greed Mr. Jenks, &quot;and when we find it we will be
+near Phantom Mountain, and the diamond makers.&quot;</p>
+
+<p>The final details were completed that night. The last of the
+supplies had been put aboard, the larder was well stocked, the
+diamond testing apparatus was stored safely away, and all that
+remained was for the adventurers to board the Red Cloud in the
+morning, and soar away.</p>
+
+<p>That night Tom was uneasy. Several times he got up, and looked
+toward the shed where the airship was stored. He could not rid
+himself of the idea that the men to whose interest it was that
+the diamond-making secret remain undiscovered, might attempt to
+wreck the airship before the start. Consequently both Eradicate
+Sampson and Engineer Jackson were on guard. Tom looked from his
+window, to the shed where the Red Cloud was housed. He saw
+nothing to cause him any uneasiness.</p>
+
+<p>&quot;I guess I'm just nervous,&quot; he mused. &quot;But, all the same, I'll
+be glad when we've started.&quot;</p>
+
+<p>They were all up early the next morning, Mr. Damon beginning
+the day by blessing the sunrise, and many other things that
+struck his fancy. The airship was wheeled out of the shed, and
+Tom gave her a final inspection.</p>
+
+<p>&quot;It's all right,&quot; he declared. &quot;All aboard!&quot;</p>
+
+<p>&quot;Now, do be careful,&quot; begged Mr. Swift. &quot;Don't take too many
+chances, Tom.&quot;</p>
+
+<p>&quot;I'll not.&quot;</p>
+
+<p>The adventurers were in the forward part of the ship, and Tom
+had taken his place at the wheels and levers in the pilot house.
+As he was about to start the motor he looked toward the road, and
+saw a horse and carriage. In the vehicle was a girlish figure, at
+the sight of which Tom blushed and smiled. He waved his hand.</p>
+
+<p>&quot;I came to wish you good luck!&quot; cried Mary Nestor, for it was
+she in the carriage.</p>
+
+<p>&quot;Thanks!&quot; cried Tom, leaning from the window of the pilot
+house. &quot;It was good of you to get up so early.&quot;</p>
+
+<p>&quot;Oh. I'm always up early,&quot; she informed him.</p>
+
+<p>&quot;Look out that the motor doesn't scare your horse,&quot; Tom warned
+her.</p>
+
+<p>&quot;Old Dobbin doesn't mind anything,&quot; was her answer. &quot;I'll see
+that he doesn't run away with me, as long as you're not on earth
+to rescue me. Good-by, Tom!&quot;</p>
+
+<p>&quot;Good-by!&quot; he called, and then he pulled the lever that set in
+motion the motor, and whirled the great propellers about. They
+whizzed around with a roar, and the Red Cloud, shivering and
+trembling with the vibration, rose in the air like some great
+bird.</p>
+
+<p>&quot;We're off for the West and Phantom Mountain!&quot; called Tom to
+his companions.</p>
+
+<p>As the airship soared upward, Eradicate Sampson ran forward
+from where he had been standing near his mule Boomerang. He waved
+his hands, and shouted something.</p>
+
+<p>&quot;Bless my hatband! What does he want?&quot; asked Mr. Damon,
+watching him curiously.</p>
+
+<p>&quot;It sounds as if he were calling to us to come back,&quot; spoke Mr.
+Parker.</p>
+
+<p>&quot;It's too late now,&quot; decided Tom. &quot;Maybe he forgot to tell us
+good-by,&quot; but, he felt a vague wonder at Eradicate's odd motions;
+for the colored man was pointing toward the stern of the airship,
+as if there was something wrong there. But the Red Cloud soared
+on.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_IX_A_WARNING_BY_WIRELESS" id="CHAPTER_IX_A_WARNING_BY_WIRELESS" />CHAPTER IX&mdash;A WARNING BY WIRELESS</h2>
+
+
+<p>Rapidly the airship ascended, and, when it was high over the
+town of Shopton, Tom headed the craft due west. Looking down he
+tried to descry Mary Nestor, in her carriage, but the trees were
+in the way, their interlocking branches hiding the girl. Tom did
+see crowds of other persons, though, thronging the streets of
+Shopton, for, though the young inventor had made many flights,
+there was always a novelty about them, that brought out the
+curious.</p>
+
+<p>&quot;A good start, Tom Swift,&quot; complimented Mr. Parker. &quot;Is it
+always as easy as this?&quot;</p>
+
+<p>&quot;Starting always is,&quot; was the answer, &quot;though, as the Irishman
+said, coming down isn't sometimes quite so comfortable.&quot;</p>
+
+<p>&quot;Bless my gizzard! That's so,&quot; cried the eccentric Mr. Damon.
+&quot;Can we vol-plane to earth in the Red Cloud, Tom?&quot;</p>
+
+<p>&quot;Yes, but not as easily as in the Butterfly. However I hope we
+will not have to. Now, Mr. Damon, if you will just take charge of
+the steering apparatus for a minute, I want to go aft.&quot;</p>
+
+<p>&quot;What for?&quot;</p>
+
+<p>&quot;I wish to see if everything is all right. I can't imagine why
+Eradicate was making those queer motions.&quot;</p>
+
+<p>Mr. Damon, who knew how to operate the Red Cloud, was soon
+guiding her on the course, while Tom made his way to the rear
+compartments, through the motor room, where the stores of
+supplies and food were kept. He made a careful examination,
+looking from an after window, and even going out on a small, open
+platform, but could discover nothing wrong.</p>
+
+<p>&quot;I guess Rad was just capering about without any special
+object,&quot; mused Tom, but it was not long after this that they
+learned to their dismay, that the colored man had had a method in
+his madness.</p>
+
+<p>On his way back through the motor room Tom looked to the
+machinery, and adjusted some of the auxiliary oil feeders. The
+various pieces of apparatus were working well, though the engine
+had not yet been speeded up to its limit. Tom wanted it to &quot;warm-up&quot;
+first.</p>
+
+<p>&quot;Everything all right?&quot; asked Mr. Damon, as Tom rejoined them
+in the pilot house, which was just forward of the living room in
+the main cabin.</p>
+
+<p>&quot;Yes, I can't imagine what made Rad act that way. But I'll set
+the automatic steering gear now, Mr. Damon, and then you will be
+relieved.&quot;</p>
+
+<p>Mr. Jenks was gazing off toward the west&mdash;to where he hoped to
+discover the secret of Phantom Mountain.</p>
+
+<p>&quot;How do you like it?&quot; asked Tom.</p>
+
+<p>&quot;It's great,&quot; replied the diamond man. &quot;I've never been in an
+airship before, and it's different than what I expected; but it's
+great! It's the only craft that will serve our purpose among the
+towering mountain peaks, where the diamond makers are hidden. I
+hope we can find them.&quot;</p>
+
+<p>In a little while the Red Cloud was skimming along at faster
+speed, guided by the automatic rudders, so that no one was needed
+in the pilot house, since there was no danger of collisions.
+Airships are not quite numerous enough for that, yet, though they
+may soon become so.</p>
+
+<p>Tom and the others devoted several hours to arranging their
+staterooms and bunks, and getting their clothing stowed away, and
+when this was done Mr. Parker and Mr. Jenks sat gazing off into
+space.</p>
+
+<p>&quot;It's hard to realize that we are really in an airship,&quot;
+observed the diamond man. &quot;At first I thought I would be
+frightened, but I'm not a bit. It doesn't seem as if anything
+could happen.&quot;</p>
+
+<p>&quot;Something is likely to happen soon,&quot; said Mr. Parker,
+suddenly, as he gazed at some weather instruments on the cabin
+wall.</p>
+
+<p>&quot;Bless my soul! Don't say that!&quot; cried Mr. Damon. &quot;What is it?&quot;</p>
+
+<p>&quot;I think, from my observations, that we will soon have a
+hurricane,&quot; said the scientific man. &quot;There is every indication
+of it&quot;'; and he seemed quite delighted at the prospect of his
+prediction coming true.</p>
+
+<p>&quot;A hurricane!&quot; cried Mr. Damon. &quot;I hope it isn't like the one
+that blew us to Earthquake Island.&quot;</p>
+
+<p>&quot;Oh, I think there will be no danger,&quot; spoke Tom. &quot;If it comes
+on to blow we will ascend or descend out of the path of the
+storm. This craft is not like the ill-fated Whizzer. I can more
+easily handle the Red Cloud; even in a bad storm.&quot;</p>
+
+<p>&quot;I'm glad to hear that,&quot; remarked Mr. Jenks. &quot;It would be too
+bad to be wrecked before we got to Phantom Mountain.&quot;</p>
+
+<p>&quot;Well, I predict that we will have a bad storm,&quot; insisted Mr.
+Parker, and Tom could not help wishing that the scientist would
+keep his gloomy forebodings to himself.</p>
+
+<p>However the storm had not developed up to noon, when Tom, with
+Mr. Damon's help, served a fine meal in the dining-room. In the
+afternoon the speed of the ship was increased, and by night they
+had covered several hundred miles. Through the darkness the Red
+Cloud kept on, making good time. Tom got up, occasionally, to
+look to the machinery, but it was all automatically controlled,
+and an alarm bell would sound in his stateroom when anything went
+wrong.</p>
+
+<p>&quot;Bless my napkin!&quot; exclaimed Mr. Damon the next morning, as
+they sat down to a breakfast of fruit, ham and eggs and fragrant
+coffee, &quot;this is living as well as in a hotel, and yet we are&mdash;how
+far are we above the earth, Tom?&quot; he asked, turning to the
+young inventor.</p>
+
+<p>&quot;About two miles now. I just sent her up, as I thought I
+detected that storm Mr. Parker spoke of.&quot;</p>
+
+<p>&quot;I told you it would come,&quot; declared the scientist, and there
+was a small hurricane below them that morning, but only the lower
+edge of it caught the Red Cloud, and when Tom sent her up still
+higher she found a comparatively quiet zone, where she slid along
+at good speed.</p>
+
+<p>That afternoon Tom busied himself about some wires and a number
+of complicated pieces of apparatus which were in one corner of
+the main cabin.</p>
+
+<p>&quot;What are you doing now?&quot; asked Mr. Jenks, who had been talking
+with Mr. Parker, and showing that scientist some of the
+manufactured diamonds.</p>
+
+<p>&quot;Getting our wireless apparatus in shape,&quot; answered the lad. &quot;I
+should have done it before, but I had so much to do that I
+couldn't get at it. I'm going to send off some messages. Dad will
+want to know how we are doing.&quot;</p>
+
+<p>As he worked away, he also made up his mind to send another
+message, in care of his father, for there was a receiving station
+in the Swift home. And to whom this message was addressed Tom did
+not say, but we fancy some of our readers can guess.</p>
+
+<p>Finally, after several hours of work, the wireless was in shape
+to send and receive messages. Tom pulled over the lever, and a
+crackling sound was heard, as the electricity leaped from the
+transmitters into space. Then he clamped the receiver on his ear.</p>
+
+<p>&quot;All ready,&quot; he announced. &quot;Has anybody any messages they wish
+sent?&quot; For, with the courtesy of a true host he was ready to
+serve his guests before he forwarded his own wireless notes.</p>
+
+<p>&quot;Just tell my wife that I'm enjoying myself,&quot; requested Mr.
+Damon. &quot;Bless my footstool! But this is great! We're off the
+earth yet, connected with it.&quot;</p>
+
+<p>Mr. Jenks had no one to whom he wanted to send any word, but
+Mr. Parker wish to wire to a fellow scientist the result of some
+observations made in the upper air.</p>
+
+<p>Tom noted all the messages down, and then, when all was in
+readiness he began to call his home station. He knew that either
+his father or Mr. Jackson, the engineer, could receive the
+wireless.</p>
+
+<p>But, no sooner had the young inventor sent off the first few
+dots and dashes representing &quot;S. I.&quot;&mdash;his home station call&mdash;than
+he started and a look of surprise came over his face.</p>
+
+<p>&quot;They're calling us!&quot; he exclaimed.</p>
+
+<p>&quot;Who is?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;My house&mdash;my father. He&mdash;he's been trying to get us ever since
+we started, but I didn't have the wireless in shape to receive
+messages. Oh, I hope it's not too late!&quot;</p>
+
+<p>&quot;Too late! Bless my soul, too late for what?&quot; gasped Mr. Damon,
+somewhat alarmed by Tom's manner.</p>
+
+<p>The lad did not answer at once. He was intently listening to a
+series of dots and dashes that clicked in the telephone receiver
+clamped to his left ear. On his face there was a look of
+worriment.</p>
+
+<p>&quot;Father has just sent me a message,&quot; he said. &quot;It's a warning
+flashed through space! He's been trying to get it to me since
+yesterday!&quot;</p>
+
+<p>&quot;What is it?&quot; asked Mr. Jenks, rising from his seat.</p>
+
+<p>&quot;The mysterious man is aboard the airship&mdash;hidden away!&quot; cried
+Tom. &quot;That's what Eradicate was trying to call to our attention
+as we started off. Eradicate saw his face at a rear window, and
+tried to warn us! The mysterious man is a stowaway on board!&quot;</p>
+

+<h2><a name="CHAPTER_X_DROPPING_THE_STOWAWAY" id="CHAPTER_X_DROPPING_THE_STOWAWAY" />CHAPTER X&mdash;DROPPING THE STOWAWAY</h2>
+
+
+<p>Tom's excited announcement startled Mr. Damon and the others as
+much as if the young inventor had informed them that the airship
+had exploded and was about to dash with them to the earth. The
+men leaped to their feet, and stared at the lad.</p>
+
+<p>&quot;A stowaway on board!&quot; cried Mr. Damon.
+&quot;Bless my soul! How did he&mdash;&quot;</p>
+
+<p>&quot;Are you sure that message is straight?&quot; asked Mr. Jenks. &quot;Did
+Eradicate see the man?&quot;</p>
+
+<p>&quot;He says he did,&quot; answered Tom. &quot;The man is hidden away on
+board now&mdash;probably among the stores and supplies.&quot;</p>
+
+<p>&quot;Bless my tomato sauce!&quot; exploded Mr. Damon. &quot;I hope he doesn't
+eat them all up!&quot;</p>
+
+<p>&quot;We must get him out at once!&quot; declared Mr. Jenks.</p>
+
+<p>&quot;I knew something would happen on this voyage,&quot; came from Mr.
+Parker. &quot;I predicted it from the first!&quot;</p>
+
+<p>Tom thought considerable, but he did not answer the scientist
+just then. Another communication was coming to him by wireless.
+He listened intently.</p>
+
+<p>&quot;Father says,&quot; the lad told his companions &quot;that Eradicate only
+had a glimpse of the man at the last moment. He was looking from
+the rear storeroom window&mdash;he's the same man who called on me
+that time&mdash;Rad remembers him very well.&quot;</p>
+
+<p>&quot;Bless my shoes! What's to be done?&quot; inquired Mr. Damon,
+looking around helplessly.</p>
+
+<p>&quot;We must get him out, that's all,&quot; decided Mr. Jenks; with
+vigor. &quot;Get him out and drop him overboard!&quot;</p>
+
+<p>&quot;Drop him overboard!&quot; cried Mr. Parker, in horror.</p>
+
+<p>&quot;Not exactly, but get rid of him,&quot; proceeded the diamond
+seeker. &quot;That man is one of my enemies. He has been sent by the
+band of diamond makers hidden among the mountains, to spy on me,
+and, if possible, prevent me from seeking to discover their
+secret. He tried to work on Tom's Swift's fears, and frighten him
+from using his airship on this quest. Then, when he failed, the
+man must have sneaked into the shed, and hidden himself in the
+ship. We must get rid of him, or he may wreck the Red Cloud!&quot;</p>
+
+<p>&quot;That's so!&quot; cried Tom. &quot;We must try to capture him. I think we
+had better&mdash;&quot; the lad paused, and again listened to the wireless
+message. &quot;Father says Eradicate saw the man have a gun, so we
+must be careful,&quot; the young inventor translated the dots and
+dashes.</p>
+
+<p>&quot;Bless my powder horn!&quot; exploded Mr. Damon.</p>
+
+<p>&quot;We shall have to proceed cautiously then,&quot; spoke Mr. Jenks.
+&quot;If he is like any others in the gang he is a desperate man.&quot;</p>
+
+<p>&quot;Better sneak up on him then, if we can,&quot; proposed Mr. Parker.
+&quot;There are enough of us to cope with one man, even if he is
+armed. You have weapons aboard, haven't you?&quot; he inquired of Tom.</p>
+
+<p>&quot;Yes,&quot; was the hesitating answer, &quot;but I don't want to use them
+if I can help it. Not only because of the danger, and a dislike
+of shedding blood, but because a stray bullet might pierce the
+gas bag and damage the ship.&quot;</p>
+
+<p>&quot;That's so,&quot; agreed Mr. Jenks. &quot;Well, I guess if we go at it
+the right way we can capture him without any shooting. But we
+must talk more quietly&mdash;we ought to have whispered&mdash;he may have
+heard us.&quot;</p>
+
+<p>&quot;I don't think so,&quot; replied Tom. &quot;The storeroom is far enough
+off so that he couldn't hear us. Besides, the motor makes such a
+racket that he couldn't distinguish what we were talking about,
+even if he heard our voices. So, unless he heard the wireless
+working, and suspects something from that, he probably doesn't
+know that we are aware of his presence aboard.&quot;</p>
+
+<p>&quot;But why do you think he has remained quiet all this while,
+Tom?&quot; asked Mr. Damon.</p>
+
+<p>&quot;Probably he wants to wait until the ship is farther out west,&quot;
+suggested Mr. Jenks. &quot;Then he will be nearer his friends, and can
+get help, if he needs it.&quot;</p>
+
+<p>&quot;And do you really believe he would destroy the Red Cloud?&quot;
+asked Mr. Parker.</p>
+
+<p>&quot;I think that all he is waiting for is a favorable chance,&quot;
+declared the diamond seeker. &quot;He would destroy the craft, and us
+too, if he could prevent us from discovering the secret of
+Phantom Mountain, I believe.&quot;</p>
+
+<p>&quot;Then we must get ahead of him,&quot; decided Tom, quietly. &quot;I have
+just flashed to dad a message, telling him that we will heed his
+warning. Now to capture the stowaway!&quot;</p>
+
+<p>&quot;And while we're about it, give him a good scare when we do get
+him,&quot; suggested Mr. Jenks.</p>
+
+<p>&quot;How?&quot; asked Tom.</p>
+
+<p>&quot;Threaten to drop him overboard. Perhaps that will make him
+tell how he happened to get in our ship, and what are the plans
+of the gang of diamond makers. We may get valuable information
+that way.&quot;</p>
+
+<p>&quot;I don't believe you can scare such fellows much,&quot; was Tom's
+opinion, but it was agreed to try.</p>
+
+<p>&quot;How are you going to capture him?&quot; asked Mr. Parker. &quot;If he
+has a gun it won't be any too easy to go in the storeroom, and
+drag him out.&quot;</p>
+
+<p>&quot;We'll have to use a little strategy,&quot; decided Tom, and then they
+discussed several plans. The one finally adopted was that Tom and Mr.
+Damon should enter the storeroom, casually, as if in search of food to
+cook for supper. They would discuss various dishes, and Mr. Damon was
+to express a preference for something in the food line, the box
+containing which, was well hack in the room. This would give the two a
+chance to penetrate to the far end of the apartment, without arousing
+the suspicions of the hidden man, who, doubtless, would be listening
+to the conversation.</p>
+
+<p>&quot;And as soon as we get sight of him, you and I will jump right
+at him, Mr. Damon,&quot; said Tom. &quot;Jump before he has a chance to use
+his gun. Mr. Jenks and Mr. Parker will be waiting outside the
+room, to catch him if he gets away from us. I'll have some ropes
+ready, and we'll tie him up, and&mdash;well, we'll decide later what
+to do with him.&quot;</p>
+
+<p>&quot;All right. I'm ready as soon as you are, Tom,&quot; said the
+eccentric man. &quot;Come ahead.&quot;</p>
+
+<p>They went softly to the storeroom, and listened at the door.
+There was no sound heard save that made by the machinery.</p>
+
+<p>&quot;I wonder if he's really here?&quot; whispered Mr. Damon.</p>
+
+<p>&quot;We'll soon find out,&quot; answered Tom. &quot;Let's go in.&quot;</p>
+
+<p>They entered, and, in pursuance of their plan, Tom and his
+friend talked of various foods.</p>
+
+<p>&quot;I think I'd like some of that canned lobster, with French
+dressing on,&quot; spoke the eccentric man.</p>
+
+<p>&quot;That's away in the back end of the room,&quot; said Tom, in a loud
+voice. &quot;It's under a lot of boxes.&quot;</p>
+
+<p>&quot;Then I'll help you get it out! Bless my frying pan! but I am
+very fond of lobster!&quot; exclaimed Mr. Damon, in as natural tones
+as was possible under the circumstances.</p>
+
+<p>He and Tom moved cautiously back among the boxes and barrels.
+They were glancing about with eager eyes. Tom switched on an
+electric light, and, the instant he did so, he was aware of a
+movement in a little space formed by one box which was placed on
+top, of two others. The lad saw a dark figure moving, as if to
+get farther out of sight.</p>
+
+<p>&quot;I've got him!&quot; cried Tom, making a dive for the shadow.</p>
+
+<p>A moment later the young inventor was bowled over, as a dark
+figure leaped over his head.</p>
+
+<p>&quot;Catch him, Mr. Damon!&quot; he cried.</p>
+
+<p>&quot;Bless my hatband! I&mdash;I&mdash;&quot; Mr. Damon's voice ended in a grunt.
+He, too, had been knocked down by the fleeing man.</p>
+
+<p>&quot;Look out, Mr. Jenks!&quot; cried Tom, to warn those on guard at the
+door of the storeroom.</p>
+
+<p>There was the report of a gun, some excited shouts, and when
+Tom could scramble to his feet, and rush out, he beheld Mr.
+Parker calmly sitting on a struggling man, while Mr. Jenks held a
+gun, that was still smoking.</p>
+
+<p>&quot;We caught him!&quot; cried the scientist.</p>
+
+<p>&quot;Anybody hurt?&quot; asked Tom, anxiously.</p>
+
+<p>&quot;No, I knocked up his gun as he fired,&quot; explained Mr. Jenks.
+&quot;Where are the ropes, Tom?&quot;</p>
+
+<p>The cords were produced and the man, who had now ceased to
+struggle, was tightly bound. He uttered not a word, but he smiled
+grimly when Mr. Damon remarked:</p>
+
+<p>&quot;I guess I'll go back in the storeroom, Tom, and see how much
+food he ate.&quot;</p>
+
+<p>&quot;Oh, I guess he didn't take much,&quot; declared the lad. &quot;He wasn't
+there long enough.&quot;</p>
+
+<p>&quot;Well, Farley Munson, so it's you, is it?&quot; asked Mr. Jenks, as
+he surveyed the prisoner.</p>
+
+<p>&quot;Do you know him?&quot; asked Tom, in some surprise.</p>
+
+<p>&quot;He was in with the diamond makers,&quot; said Mr. Jenks. &quot;He was
+one of those who took me to the secret cave. But it will be the
+last time he ever goes there. How high up are we, Tom?&quot;</p>
+
+<p>&quot;About two miles. Why?&quot;</p>
+
+<p>&quot;I guess that will be far enough to let him fall,&quot; went on the
+diamond seeker. &quot;Come on, Mr. Damon, help me throw him overboard!&quot;</p>
+
+<p>&quot;You&mdash;you're not going to throw me over&mdash;with the airship two
+miles high; are you?&quot; gasped the man.</p>
+
+<p>&quot;Will you tell us what we want to know, if we don't?&quot; asked Mr.
+Jenks.</p>
+
+<p>&quot;What do you want to know?&quot;</p>
+
+<p>&quot;How you got aboard, and what your object was in coming.&quot;</p>
+
+<p>&quot;That's easy enough. I had been hanging around the shed for
+several days, watching a chance to get in. Finally I saw it, when
+that colored man went to feed his mule, and I slipped in, and
+hid in the airship. The stores were all in then, and I stowed
+myself away among the boxes. I had food and water, so I didn't
+touch any of yours,&quot; and he looked at Mr. Damon, who seemed much
+relieved.</p>
+
+<p>&quot;And what was your object?&quot; demanded Mr. Jenks.</p>
+
+<p>&quot;I wanted to prevent you from going to Phantom Mountain.&quot;</p>
+
+<p>&quot;How?&quot;</p>
+
+<p>&quot;By destroying the airship if need be. But I hoped to
+accomplish it by other means. I would have stopped at nothing,
+though, to prevent you. You must keep away from there!&quot;</p>
+
+<p>&quot;And if we refuse?&quot; asked Tom.</p>
+
+<p>&quot;Then you'll have to take what comes!&quot;</p>
+
+<p>&quot;But not from you!&quot; exclaimed Mr. Jenks. &quot;We're going to get
+rid of you.&quot;</p>
+
+<p>The man's face showed the alarm he felt.</p>
+
+<p>&quot;Oh, don't worry,&quot; said Mr. Jenks, quickly, &quot;we're not going to
+toss you overboard. We're not as desperate as your crowd. But
+we're going to get rid of you, and then go on before you can send
+any word to your confederates. We'll put you off in the most
+lonesome spot we can find, and I guess you'll be some time
+getting back to civilization. By that time we'll have the secret
+of the diamonds.&quot;</p>
+
+<p>&quot;You never will!&quot; declared the man, firmly. And he would say
+nothing more, though by threats and promises Mr. Jenks tried to
+get from him something about the men in with him, and where the
+cave of the diamonds was located.</p>
+
+<p>Heavily bound with ropes the man was locked in a small closet,
+to be kept there until a favorable spot was reached for letting
+him go. Mr. Jenks' plan, of dropping him down in some place where
+he would have difficulty in sending on word to his confederates
+was considered a good one.</p>
+
+<p>Three days later, in crossing over a lonely region, near the
+Nebraska National Forest, Farley Munson, which was one of the
+names the spy went by, was dropped off the airship, when it was
+sent down to within a few feet of the earth.</p>
+
+<p>&quot;It will take you some time to get to a telegraph office,&quot; said
+Mr. Jenks, as a package of food, and a flask of water was tossed
+down to the stowaway. He shook his fist at those in the airship,
+and shouted after them:</p>
+
+<p>&quot;You'll never discover the secret of Phantom Mountain!&quot;</p>
+
+<p>&quot;Yes, we will,&quot; declared Tom, as he sent the Red Cloud high
+into the air again.</p>
+
+
+
+<p>CHAPTER XI&mdash;A WEARY SEARCH</p>
+
+
+<p>During the three days when the stowaway had been kept a
+prisoner, the Red Cloud had made good time on her western trip.
+She was now about two hundred and fifty miles from Leadville,
+Colorado, and Tom knew he could accomplish that distance in a
+short time. It was necessary, therefore, since they were so close
+to the place where the real search would begin, to make some more
+definite plans.</p>
+
+<p>&quot;We will need to replenish our supply of gasoline,&quot; said Tom,
+shortly after the stowaway had been dropped, and when the young
+inventor had made a general inspection of the airship.</p>
+
+<p>&quot;Is it all gone?&quot; inquired Mr. Damon.</p>
+
+<p>&quot;Not all, but we will soon be in the wildest part of the Rocky
+Mountains, and gasoline is difficult to procure there. So I want
+to fill all our reserve tanks. But I would rather do that before
+we get far into Colorado.&quot;</p>
+
+<p>&quot;Why?&quot; inquired Mr. Parker.</p>
+
+<p>&quot;Because airships are not so common but what the appearance of
+one attracts attention. Ours is sure to be talked about, and
+commented on. In that case, in spite of our precaution in putting
+Munson off in this lonely place, word of the Red Cloud being in
+the vicinity of Leadville may reach the diamond makers, and put
+them on their guard. We want to take them unawares if we can.&quot;</p>
+
+<p>&quot;That's so,&quot; agreed Mr. Jenks. &quot;We had better get our gasoline
+at the first stopping place, then, and proceed with our search.
+Our first object ought to be to look for the landmark&mdash;the head
+of stone. Then we can begin to prospect about a bit.&quot;</p>
+
+<p>&quot;My idea, exactly,&quot; declared Tom. &quot;Well, then, I'll go down at
+the first place we cross, where we can get gasoline, and then
+we'll be in a position to hover in the air for a long time,
+without descending.&quot;</p>
+
+<p>The airship kept on her way, traveling slowly the remainder of
+that day, and at dusk, when there was less chance of big crowds
+seeing them, the Red Cloud was sent down on the outskirts of a
+large village. Tom and Mr. Damon went to a supply store, and
+arranged to have a sufficient quantity of the gasoline taken out
+to the airship. It was delivered after dark, and little talk was
+occasioned by the few who were aware of the presence of the
+craft. Then, once more, they went aloft, and Tom sent several
+wireless messages to Shopton, including one to Miss Nestor.</p>
+
+<p>&quot;Please tell my wife that I am well, and that I have a good
+appetite,&quot; said Mr. Damon.</p>
+
+<p>Mr. Parker also sent a message to a scientific friend of his, stating
+that he made some observations among the mountains, of the region in
+which the airship then was, and that the indications were that a great
+landslide would soon take place.</p>
+
+<p>&quot;That won't worry us,&quot; spoke Tom, &quot;for we'll be far above it.&quot;</p>
+
+<p>&quot;I hope we will be near enough to enable me to observe it, and
+make some scientific notes,&quot; came from Mr. Parker. &quot;I am positive
+that one of these mountain peaks that we saw to-day will
+disappear in a landslide within a few days. I have an instrument
+somewhat like the one that records earthquakes, and it has been
+acting strangely of late.&quot;</p>
+
+<p>Tom wondered what enjoyment Mr. Parker got out of life, when he
+was always looking for some calamity to happen, but the scientist
+seemed to take as much pleasure in his gloomy forebodings now, as
+he had on Earthquake Island.</p>
+
+<p>They reached the vicinity of Leadville the next day, but took
+care to keep high above the city, so that the airship could not
+be observed. With powerful glasses they examined the mountainous
+country, looking for the little settlement of Indian Ridge.</p>
+
+<p>&quot;There it is!&quot; exclaimed Mr. Jenks, just as dusk was settling
+down. I can make out the hotel I stopped at. Now we can really
+begin our search. The next thing is to find the stone head, and
+then, I think, I will have my bearings.&quot;</p>
+
+<p>&quot;We'll begin the hunt for that landmark in the morning,&quot; said
+Tom.</p>
+
+<p>High in the air hovered the Red Cloud. At that distance above
+the earth she must have looked like some great bird, and the
+adventurers thought it unlikely that any one in the vicinity of
+Leadville would observe them.</p>
+
+<p>The quest for the great mountain peak, that looked like a stone
+head, was under way. Back and forth sailed the airship. Sometimes
+she was enveloped in fog, and no sight could be had of the earth
+below. At other times there were rain storms, which likewise
+prevented a view. Mr. Parker was on the lookout for his predicted
+mountain landslide, but it did not occur, and he was much
+disappointed.</p>
+
+<p>&quot;It's queer I can't pick out that landmark,&quot; said Mr. Jenks
+after two days of weary searching, when their eyes were strained
+from long peering through telescopes. &quot;I'm sure it was around
+Indian Ridge, yet we've covered almost all the ground in this
+neighborhood, and I haven't had a glimpse of it.&quot;</p>
+
+<p>&quot;Perhaps it was destroyed in a landslide, or some cataclysm of
+nature,&quot; suggested Mr. Parker. &quot;That is very possible.&quot;</p>
+
+<p>&quot;If that's the case we're going to have a hard time to locate
+the cave of the diamond makers,&quot; answered Mr. Jenks, &quot;but I hope
+it isn't so.&quot;</p>
+
+<p>They continued the search for another day, and then Tom, as
+they sat in the comfortable cabin of the airship that night,
+hovering almost motionless (for the motor had been shut down)
+made a proposition.</p>
+
+<p>&quot;Why not descend in some secluded place,&quot; he suggested, &quot;and
+wander around on foot, making inquiries of the miners. They may
+know where the stone head is, or they may even know about Phantom
+Mountain.&quot;</p>
+
+<p>&quot;Good idea,&quot; spoke Mr. Jenks. &quot;We'll do it.&quot;</p>
+
+<p>Accordingly, the next morning, the Red Cloud was lowered in a
+good but lonely landing place, and securely moored. It was in a
+valley, well screened from observation, and the craft was not
+likely to be seen, but, to guard against any damage being done to
+it by passing hunters or miners, Mr. Parker and Mr. Damon agreed
+to remain on guard in it, while Tom and Mr. Jenks spent a day or
+two traveling around, making inquiries.</p>
+
+<p>The young inventor and his companion proceeded on foot to a
+small settlement, where they hired horses on which to make their
+way about. They were to be gone two days, and in that time they
+hoped to get on the right trail.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XII_THE_GREAT_STONE_HEAD" id="CHAPTER_XII_THE_GREAT_STONE_HEAD" />CHAPTER XII&mdash;THE GREAT STONE HEAD</h2>
+
+
+<p>It was a wild and desolate country in which Tom Swift and Mr.
+Jenks were traveling. Villages were far apart, and they were at
+best but small settlements. In their journeys from place to place
+they met few travelers.</p>
+
+<p>But of these few they made cautious inquiries as to the
+location of Phantom Mountain, or the landmark known as the great
+stone head. Prospectors, miners and hunters, whom they asked,
+shook their heads.</p>
+
+<p>&quot;I've heard of Phantom Mountain,&quot; said one grizzled miner, &quot;but
+I couldn't say where it is. Maybe it's only a fish story&mdash;the
+place may not even exist.&quot;</p>
+
+<p>&quot;Oh, it does, for I've been there!&quot; exclaimed Mr. Jenks.</p>
+
+<p>&quot;Then why don't you go back to it?&quot; asked the miner.</p>
+
+<p>&quot;Because I can't locate it again,&quot; was the reply.</p>
+
+<p>&quot;Humph! Mighty queer if you've seen a place once, and can't get
+to it again,&quot; and the man looked as if he thought there was
+something strange about Tom and his companion. Mr. Jenks did not
+want to say that he had been taken to the mountain blindfolded,
+for that would have caused too much talk.</p>
+
+<p>&quot;I think if we spent to-night in a place where the miners
+congregate, listened to their talk, and put a few casual
+questions to them, more as if we were only asking out of idle
+curiosity, we might learn something,&quot; suggested Tom.</p>
+
+<p>&quot;Very well, we'll try that scheme.&quot;</p>
+
+<p>Accordingly, after they had left the suspicious miner the two
+proceeded to a small milling town, not far from Indian Ridge.
+There they engaged rooms for the night at the only hotel, and,
+after supper they sat around the combined dance hall and gambling
+place.</p>
+
+<p>There were wild, rough scenes, which were distasteful to Tom,
+and to Mr. Jenks, but they felt that this was their only chance
+to get on the right trail, and so they stayed. As strangers in a
+western mining settlement they were made roughly welcome, and in
+response to their inquiries about the country, they were told
+many tales, some of which were evidently gotten up for the
+benefit of the &quot;tenderfeet.&quot;</p>
+
+<p>&quot;Is there a place around here called Phantom Mountain?&quot; asked
+Tom, at length, as quietly as he could.</p>
+
+<p>&quot;Never heard of it, stranger,&quot; replied a miner who had done
+most of the talking. &quot;I never heard of it, and what Bill
+Slatterly don't know ain't worth knowin'. I'm Bill Slatterly,&quot; he
+added, lest there be some doubt on that score.</p>
+
+<p>&quot;Isn't there some sort of a landmark around here shaped like a
+great stone head?&quot; went on Tom, after some unimportant questions.
+&quot;Seems to me I've heard of that.&quot;</p>
+
+<p>&quot;Nary a one,&quot; answered Mr. Slatterly. &quot;No stone heads, and no
+Phantom Mountains&mdash;nary a one.</p>
+
+<p>&quot;Who says there ain't no Phantom Mountains?&quot; demanded an
+elderly miner, who had been dozing in one corner of the room, but
+who was awakened by Slatterly's loud voice. &quot;Who says so?&quot;</p>
+
+<p>&quot;I do,&quot; answered the one who claimed to know everything.</p>
+
+<p>&quot;Then you're wrong!&quot; Tom's heart commenced beating faster than
+usual.</p>
+
+<p>&quot;Do you mean to say you've seen Phantom Mountain, Jed Nugg?&quot;
+demanded Slatterly.</p>
+
+<p>&quot;No, I ain't exactly seen it, an' I don't want to, but there is
+such a place, about sixty mile from here. Folks says it's
+haunted, and them sort of places I steer clear from.&quot;</p>
+
+<p>&quot;Can you tell me about it?&quot; asked Mr. Jenks, eagerly. &quot;I am
+interested in such things.&quot;</p>
+
+<p>&quot;I can't tell you much about it,&quot; was the reply, &quot;and I
+wouldn't git too interested, if I was you. It might not be
+healthy. All I know is that one time my partner and I were in
+hard luck. We got grub-staked, and went out prospectin'. We
+strayed into a wild part of the country about sixty mile from
+here, and one night we camped on a mountain&mdash;a wild, desolate
+place it was too.&quot;</p>
+
+<p>The miner stopped, and began leisurely filling his pipe.</p>
+
+<p>&quot;Well?&quot; asked Tom, trying not to let his voice sound too eager.</p>
+
+<p>&quot;Well, that was Phantom Mountain.&quot;</p>
+
+<p>The miner seemed to have finished his story.</p>
+
+<p>&quot;Is that all?&quot; asked Mr. Jenks. &quot;How did you know it was
+Phantom Mountain?&quot;</p>
+
+<p>&quot;'Cause we seen the ghost&mdash;my partner and I&mdash;that's why!&quot;
+exclaimed the man, puffing on his pipe. &quot;As I said, we was
+campin' there, and 'long about midnight we seen somethin' tall
+and white, and all shimmerin', with a sort of yellow fire,
+slidin' down the side of the mountain It made straight for our
+camp.&quot;</p>
+
+<p>&quot;Huh! Guess you run, didn't you, Jed?&quot; asked Bill Slatterly.</p>
+
+<p>&quot;Course we did. You'd a run too, if you seen a ghost comm' at
+you, an' firm' a gun.&quot;</p>
+
+<p>&quot;Ghosts can't fire guns!&quot; declared Bill. &quot;I guess you dreamed
+it, Jed.&quot;</p>
+
+<p>&quot;Ghosts can't fire guns, eh? That's all you know about it. This
+one did, and to prove I didn't dream it, there was a bullet hole
+in my hat next mornin'. I could prove it, too, only I ain't got
+that hat any more. But that was Phantom Mountain, strangers, an'
+my advice to you is to keep away from it. I was on it but I
+didn't exactly see it, 'cause it was dark at the time.&quot;</p>
+
+<p>&quot;Was it near a peak that looked like a stone
+head?&quot; asked Tom.</p>
+
+<p>&quot;It were, stranger, but I didn't take much notice of it. Me and
+my partner got out of them diggin's next day, and I never went
+back. I ain't never said much about this place, but it's called
+Phantom Mountain all right, and I ain't the only one that's seen
+a ghost there. Other grub-stakers has had the same experience.&quot;</p>
+
+<p>&quot;Why ain't I never heard about it?&quot; demanded Bill,
+suspiciously.</p>
+
+<p>&quot;'Cause as why you're allers so busy talkin' that you don't
+never listen to nothin' I reckon,&quot; was Jed's answer, amid
+laughter.</p>
+
+<p>&quot;Can you tell us what trail to take to get there?&quot; asked Tom,
+of the miner.</p>
+
+<p>&quot;Yes, it's called the old silver trail, and you strike it by
+goin' to a place called Black Gulch, about forty mile from here.
+Then it's twenty mile farther on. But take my advice and don't
+go.&quot;</p>
+
+<p>&quot;Can it be reached by way of Indian Ridge?&quot; asked Mr. Jenks,
+wondering how he had been taken to the cave of the diamond
+makers. He did not remember Black Gulch.</p>
+
+<p>&quot;Yes, you can git there by Indian Ridge way, but it's more
+dangerous. You're likely to lose your way, for that's a trail
+that's seldom traveled.&quot; Mr. Jenks thought that, perhaps, was the
+reason the gang had taken him that way. &quot;It's easier to get to
+the stone head and Phantom Mountain by Black Gulch, but it ain't
+healthy to go there, strangers, take my advice on that,&quot;
+concluded the miner, as he prepared to go to sleep again.</p>
+
+<p>Tom could scarcely contain the exultation he felt. At last, it
+seemed, they were on the trail. He motioned to Mr. Jenks, and
+they slipped quietly from the place, just as another dance was
+beginning.</p>
+
+<p>&quot;Now for Black Gulch!&quot; cried Tom. &quot;We must hurry back to the
+airship, and tell the good news.</p>
+
+<p>&quot;It's too late to-night,&quot; decided Mr. Jenks, and so they waited
+until morning, when they made an early start.</p>
+
+<p>They found Mr. Damon and Mr. Parker anxiously awaiting their
+return. Mr. Damon blessed so many things that he was nearly out
+of breath, and Mr. Parker related something of the observations
+he had made.</p>
+
+<p>&quot;I think I have discovered traces of a dormant volcano,&quot; he
+said. &quot;I am in hopes that it will have an eruption while we are
+here.&quot;</p>
+
+<p>&quot;I'm not,&quot; spoke Tom, decidedly. &quot;We'll start for Black Gulch
+as soon as possible.&quot;</p>
+
+<p>The airship once more rose in the air, and, following the
+directions the miner had given him, Tom pointed his craft for the
+depression in the mountains which had been given the name Black
+Gulch. It was reached in a short time, and then, making a turn up
+a long valley the airship proceeded at reduced speed.</p>
+
+<p>&quot;We ought to see that stone head soon now,&quot; spoke Tom, as he
+peered from the windows of the pilot house.</p>
+
+<p>&quot;It's queer we didn't notice it when we were up in the air,&quot;
+remarked Mr. Jenks. &quot;We've been over this place before, I'm sure
+of it.&quot;</p>
+
+<p>The next moment Mr. Damon uttered a cry. &quot;Bless my watch-chain!&quot;
+he exclaimed. &quot;Look at that!&quot;</p>
+
+<p>He pointed off to the left. There, jutting out from the side of
+a steep mountain peak was a mass of stone&mdash;black stone&mdash;which, as
+the airship slowly approached, took the form and shape of a
+giant's head.</p>
+
+<p>&quot;That's it! That's it!&quot; cried Tom. &quot;The great stone head!&quot;</p>
+
+<p>&quot;And now for Phantom Mountain and the diamonds!&quot; shouted Mr.
+Jenks, as Tom let the airship slowly settle to the bottom of the
+valley.</p>
+
+

+<h2><a name="CHAPTER_XIII_ON_PHANTOM_MOUNTAIN" id="CHAPTER_XIII_ON_PHANTOM_MOUNTAIN" />CHAPTER XIII&mdash;ON PHANTOM MOUNTAIN</h2>
+
+
+<p>Out from the Red Cloud piled Tom and the others. They made a
+rush for the irregular mass of rock which bore so strong a
+resemblance to the head of some gigantic man.</p>
+
+<p>&quot;That's the one! That's the thing I saw when they were taking
+me along here blindfolded!&quot; exclaimed Mr. Jenks. &quot;I'm sure we're
+on the right trail, now!&quot;</p>
+
+<p>&quot;But what gets me, though,&quot; remarked Mr. Damon, &quot;is why we
+couldn't see that landmark when we were up in the air. We had a
+fine view, and ought to have been able to pick it out with the
+telescopes.&quot;</p>
+
+<p>The adventurers saw the reason a few seconds later. The image
+was visible only from one place, and that was directly looking up
+the valley. If one went too far to the right or left the head
+disappeared from view behind jutting crags, and it was impossible
+to see it from overhead, because the head was almost under a
+great spur of a mighty mountain.</p>
+
+<p>&quot;We might have hunted for it a week in the airship, and been
+directly over it,&quot; said Tom, &quot;and yet we would never have seen
+it.&quot;</p>
+
+<p>&quot;Yes, but we never would have gotten here in such good shape if
+it hadn't been for your wonderful craft,&quot; declared Mr. Jenks. &quot;It
+brought us here safely and quickly, and enabled us to elude the
+men who tried to keep us back. We're here in spite of them. If we
+had traveled by train they might have interfered with us in a
+dozen ways.&quot;</p>
+
+<p>&quot;That's so,&quot; agreed Mr. Damon. &quot;Well, now we're here, what's to
+be done? Which way do we start to reach the cave where the
+diamonds are manufactured, Mr. Jenks?&quot;</p>
+
+<p>&quot;That I can't say. As you know, I only had a momentary glimpse
+of this stone head as they wore taking me along the trail. Then
+one the men noticed that the bandage had slipped and he pulled it
+into place. So I really can't say which direction to take now, in
+order to discover the secret.&quot;</p>
+
+<p>&quot;How long after you saw the head before you reached the cave?&quot;
+asked Tom. &quot;In that way we may be able to tell how far away it
+is.&quot;</p>
+
+<p>&quot;Well, I should say it was about two or three hours after I saw
+the head, before we got to the halting place, and I was carried
+into the cave. That would make it several miles from here, for we
+went in a wagon.&quot;</p>
+
+<p>&quot;Yes, and they might have driven in a round-about way, in order
+to deceive you,&quot; suggested Mr. Damon. &quot;At best we have but a
+faint idea where the diamond cave is, but we must search for it;
+eh, Tom?&quot;</p>
+
+<p>&quot;Certainly. We'll start right in. And as the airship will be of
+but little service to us now, I suggest that we leave it in this
+valley. It is very much secluded, and no one will harm it, I
+think. We can then start off prospecting, for I have a large
+portable tent, and we can carry enough food with us, with what
+game we can shoot, to enable us to live. I have a regular camping
+outfit on board.&quot;</p>
+
+<p>&quot;Fine!&quot; cried Mr. Parker, &quot;and that will give me a chance to
+make some observations among the mountains, and perhaps I can
+predict when a landslide, or an eruption of some dormant volcano,
+may occur.&quot;</p>
+
+<p>&quot;Bless my stars!&quot; cried Mr. Damon. &quot;I don't wish you any bad
+luck, Mr. Parker, but I sincerely hope nothing of the sort
+happens! We had enough of that on Earthquake Island!&quot;</p>
+
+<p>&quot;One can not halt the forces of nature,&quot; said the scientist,
+solemnly. &quot;There are many towering peaks around here which may
+contain old volcanoes. And I notice the presence of iron ore all
+about. This must be a wonderful place in a thunder and lightning
+storm.&quot;</p>
+
+<p>&quot;Why?&quot; asked Tom, curiously.</p>
+
+<p>&quot;Because lightning would be powerfully attracted here by the
+presence of the metal. In fact there is evidence that many of the
+peaks have been struck by lightning,&quot; and the scientist showed
+curious, livid scars on the stone faces of the peaks within
+sight.</p>
+
+<p>&quot;Then this is a good place to stay away from in a storm,&quot;
+observed Mr. Damon. &quot;However, we won't worry about that now. If
+this is the landmark Mr. Jenks was searching for, then we must be
+in the vicinity of Phantom Mountain.&quot;</p>
+
+<p>&quot;I think we are,&quot; declared the diamond seeker. &quot;Probably it is
+within sight now, but there are so many peaks, and this is such a
+wild and desolate part of the country that we may have trouble in
+locating it.&quot;</p>
+
+<p>&quot;We've got to make a beginning, anyhow,&quot; decided Tom, &quot;and the
+sooner the better. Come, we'll make up our camping kits, and
+start out.&quot;</p>
+
+<p>It was something to know that they were on the right trail, and
+it was a relief to be able to busy oneself, and not be aimlessly
+searching for a mysterious landmark. They all felt this, and soon
+the airship was taken to a secluded part of the valley, where it
+was well hidden from sight in a grove of trees.</p>
+
+<p>Tom and Mr. Damon then served a good meal, and preparations
+were made to start on their search among the mountains&mdash;a search
+which they hoped would lead them to Phantom Mountain, and the
+cave of the diamond makers.</p>
+
+<p>The tent which would afford them shelter was in sections, and
+could be laced together. They carried food, compressed into small
+packages, coffee, a few cooking utensils; and each one had a gun,
+Tom carrying a combination rifle and shotgun, for game.</p>
+
+<p>&quot;We can't live very high while we're on the trail,&quot; said the
+young inventor, &quot;but it won't be much worse than it was on
+Earthquake Island. Are we all ready?&quot;</p>
+
+<p>&quot;I guess so,&quot; answered Mr. Damon. &quot;How long are we going to be
+away?&quot;</p>
+
+<p>&quot;Until we find the diamond makers!&quot; declared Tom, firmly.</p>
+
+<p>Shouldering their packs, the adventurers started off. Tom
+turned for a last look at his airship, dimly seen amid the trees.
+Would he ever come back to the Red Cloud? Would she be there when
+he did return? Would their quest be successful? These questions
+the lad asked himself, as he followed his companions along the
+rocky trail.</p>
+
+<p>&quot;Perhaps we can find the road by which these men go in and out
+of the cave,&quot; suggested Mr. Damon, when they had gone on for
+several miles.</p>
+
+<p>&quot;I fancy not,&quot; replied Mr. Jenks. &quot;They probably take great
+pains to hide it. I think though, that our best plan will be to
+go here and there, looking for the entrance to the cave. I
+believe I would remember the place.&quot;</p>
+
+<p>&quot;But why can't you follow the directions given by the miner who
+told you about Phantom Mountain?&quot; asked Mr. Damon.</p>
+
+<p>&quot;Because his talk was too indefinite,&quot; answered Mr. Jenks. &quot;He
+was so frightened by seeing what he believed to be a ghost, that
+he didn't take much notice of the location of the place. All he
+knows is that Phantom Mountain is somewhere around here.&quot;</p>
+
+<p>&quot;And we've got to hunt until we find it; is that the idea?&quot;
+asked Mr. Parker.</p>
+
+<p>&quot;Or until we see the phantom&quot; added Tom, in a low voice.</p>
+
+<p>&quot;Bless my topknot!&quot; exclaimed Mr. Damon. &quot;You don't mean to say
+you expect to see that ghost; do you Tom?&quot;</p>
+
+<p>&quot;Perhaps,&quot; answered the young inventor, and he did not add
+something else of which he was thinking. For Tom had a curious
+theory regarding the phantom.</p>
+
+<p>They tramped about the remainder of that day. Toward evening
+Tom shot some birds, which made a welcome addition to their
+supper. Then the tent was put together, some spruce and hemlock
+boughs were cut to make a soft bed, and on these, while the light
+of a campfire gleamed in on them, the adventurers slept.</p>
+
+<p>Their experience the following day was similar to the first.
+They saw no evidence of a large cave such as Mr. Jenks had
+described, nor were there any traces of men having gone back and
+forth among the mountains, as might have been expected of the
+diamond makers, for, as Mr. Jenks had said, they made frequent
+journeys to the settlement for food, and other supplies.</p>
+
+<p>&quot;Well, I haven't begun to give up yet,&quot; announced Tom, on the
+third day, when their quest was still unsuccessful. &quot;But I think
+we are making one mistake.&quot;</p>
+
+<p>&quot;What is that?&quot; inquired Mr. Jenks.</p>
+
+<p>&quot;I think we should go up higher. In my opinion the cave is near
+the top of some peak; isn't it, Mr. Jenks?&quot;</p>
+
+<p>&quot;I have that impression, though, as you know, I never saw the
+outside of it. Still, it might not be a bad idea to ascend some
+of these peaks.&quot;</p>
+
+<p>Following this suggestion, they laid their trail more toward
+the sky, and that night found them encamped several thousand feet
+above the sea-level. It was quite cool, and the campfire was a
+big one about which they sat after supper, talking of many
+things.</p>
+
+<p>Tom did not sleep well that night. He tossed from side to side
+on the bed of boughs, and once or twice got up to replenish the
+fire, which had burned low. His companions were in deep slumber.</p>
+
+<p>&quot;I wonder what time it is?&quot; mused Tom, when he had been up the
+third time to throw wood on the blaze. &quot;Must be near morning.&quot; He
+looked at his watch, and was somewhat startled to see that it was
+only a little after twelve. Somehow it seemed much later.</p>
+
+<p>As he was putting the timepiece back into his pocket the lad
+looked around at the dark and gloomy mountains, amid which they
+were encamped. As his gaze wandered toward the peak of the one on
+the side of which the tent was pitched, he gave a start of
+surprise.</p>
+
+<p>For, coming down a place where, that afternoon, Tom had noticed
+a sort of indefinite trail was a figure in white. A tall, waving
+figure, which swayed this way and that&mdash;a figure which halted and
+then came on again.</p>
+
+<p>&quot;I wonder&mdash;I wonder if that can be a wisp of fog?&quot; mused the
+young inventor. He rubbed his eyes, thinking it might be a
+swirling of the night mist or a defect of vision. Then, as he saw
+more plainly, he noticed the thing in white rushing toward him.</p>
+
+<p>&quot;It's the phantom&mdash;the phantom!&quot; cried Tom, aloud. &quot;It's the
+thing the miner saw! We're on Phantom Mountain now!&quot;</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XIV_WARNED_BACK" id="CHAPTER_XIV_WARNED_BACK" />CHAPTER XIV&mdash;WARNED BACK</h2>
+
+
+<p>Tom's cries awakened the sleepers in the tent. Mr. Damon was
+the first to rush out.</p>
+
+<p>&quot;Bless my nightcap, Tom!&quot; he cried. &quot;What is it? What has
+happened? Are we attacked by a mountain lion?&quot;</p>
+
+<p>For answer the young inventor pointed up the mountain, to
+where, in the dim light from a crescent moon, there stood boldly
+revealed, the figure in white.</p>
+
+<p>&quot;Bless&mdash;bless my very existence!&quot; cried the odd man. &quot;What is
+it, Tom?&quot;</p>
+
+<p>&quot;The phantom,&quot; was the quiet answer. &quot;Watch it, and see what it
+does.&quot;</p>
+
+<p>By this time Mr. Jenks and Mr. Parker had joined Tom and Mr.
+Damon. The four diamond seekers stood gazing at the apparition.
+And, as they looked, the thing in white, seemingly too tall for
+any human being, slid slowly forward, with a gliding motion. Then
+it raised its long, white arms, and waved them threateningly at
+the adventurers.</p>
+
+<p>&quot;It's motioning us to go back,&quot; said Mr. Parker in an awed
+whisper. &quot;It doesn't want us to go any farther.&quot;</p>
+
+<p>&quot;Very likely,&quot; agreed Tom, coolly. &quot;But we're not going to be
+frightened by anything like that; are we?&quot;</p>
+
+<p>&quot;Not much!&quot; exclaimed Mr. Jenks. &quot;I expected this. A ghost
+can't drive me back from getting my rights from those scoundrels!&quot;</p>
+
+<p>&quot;Suppose it uses a revolver to back up its demand?&quot; asked the
+scientist.</p>
+
+<p>&quot;Wait until it does,&quot; answered Mr. Jenks. But the figure in
+white evidently had no such intentions. It came on a little
+distance farther, still waving the long arms threateningly, and
+then it suddenly disappeared, seeming to dissolve in the misty
+shadows of the night.</p>
+
+<p>&quot;Bless my suspenders!&quot; cried Mr. Damon. &quot;That's a very
+strange proceeding! Very strange! What do you make of it, Tom?&quot;</p>
+
+<p>&quot;It is evidently some man dressed up in a sheet,&quot; declared Mr.
+Jenks. &quot;I expected as much.&quot;</p>
+
+<p>&quot;The work of those diamond makers; do you think?&quot; continued Mr.
+Damon.</p>
+
+<p>&quot;I believe so,&quot; answered Tom, slowly, for he was trying to
+think it out. &quot;I believe they are the cause of the phantom,
+though I don't know that it's a man dressed in a sheet.&quot;</p>
+
+<p>&quot;Why isn't it?&quot; demanded Mr. Jenks.</p>
+
+<p>&quot;Because it was too tall for a man, unless he's a giant.&quot;</p>
+
+<p>&quot;He may have been on stilts,&quot; suggested Mr. Parker.</p>
+
+<p>&quot;No man on stilts could walk along that way,&quot; declared Tom,
+confidently. &quot;He glided along too easily. I am inclined to think
+it may be some sort of a light.&quot;</p>
+
+<p>&quot;A light?&quot; queried Mr. Damon.</p>
+
+<p>&quot;Yes, the diamond makers may be hidden in some small cave near
+here, and they may have some sort of a magic lantern or a similar
+arrangement, for throwing a shadow picture. They could arrange it
+to move as they liked, and could cause it to disappear at will.
+That, I think, is the ghost we have just seen.&quot;</p>
+
+<p>&quot;But the diamond makers have only been in this mountain
+recently,&quot; objected Mr. Jenks, &quot;and the phantom was here before
+them. In fact, that was what gave the place its name.&quot;</p>
+
+<p>&quot;That may be,&quot; admitted the lad. &quot;There are many places that
+have the name of being haunted, but no one ever sees the ghost.
+It is always some one else, who has heard of some one who has
+seen it. That may have been the case here. I grant that this
+place may have been called 'Phantom Mountain' for a number of
+years, due to the superstitious tales of miners. The diamond
+makers came along, found the conditions just right for their
+work, and adopted the ghost, so to speak. As there wasn't any
+real spirit they made one, and they use it to scare people away.
+I think that's what we've just seen, though I may be wrong in my
+theory as to what the phantom is.&quot;</p>
+
+<p>&quot;Well, it's gone now, at any rate,&quot; said Mr. Jenks, &quot;and I
+think we'd better get back inside the tent. It's cold out here.&quot;</p>
+
+<p>&quot;Aren't some of us going to stand guard?&quot; demanded Mr. Damon.</p>
+
+<p>&quot;What for?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;Why&mdash;er&mdash;bless my key-ring! Suppose that ghost takes a notion
+to come down here, and use his gun, as he did on the miners?&quot;</p>
+
+<p>&quot;I don't believe that will happen,&quot; remarked Tom. &quot;The diamond
+makers, if the white thing had anything to do with them, have
+given us a warning, and I think they'll at least wait until
+morning to see how we heed it.&quot;</p>
+
+<p>&quot;We aren't going to heed it!&quot; burst out Mr. Jenks. &quot;I'm going
+to go right ahead and find that cave where they make diamonds!&quot;</p>
+
+<p>&quot;And we're with you!&quot; exclaimed Tom. &quot;We'll have a good fire
+going the rest of the night, and that may keep intruders away. In
+the morning we'll begin our search, and we'll go up the trail
+where we saw the white figure.&quot;</p>
+
+<p>A big pile of wood had been collected for the fire, and Tom now
+piled some logs and branches on the blaze. It would last for some
+time now, and the adventurers, still talking of the &quot;ghost&quot; went
+back into the tent. It was over an hour before they all got to
+sleep again, and Mr. Jenks and Mr. Damon took turns in getting up
+once or twice during the remainder of the night to replenish the
+fire.</p>
+
+<p>Morning dawned without anything further having occurred to
+disturb them, and, after a hearty breakfast, to which Tom added
+some fish he caught in a nearby mountain stream, they set off up
+the trail on Phantom Mountain.</p>
+
+<p>They had left their tent standing, as they proposed making that
+spot their headquarters until they located the cave they were
+seeking. What their course would be after that would depend on
+the circumstances.</p>
+
+<p>If they had expected to have an easy task locating the cavern
+in which Mr. Jenks had seen diamonds made, the adventurers were
+disappointed. All that day they tramped up and down the mountain,
+looking for some secret entrance, but none was disclosed. The
+higher they went up the great peak, the fainter became the trail,
+until, at length it vanished completely.</p>
+
+<p>But this was not to be wondered at, since it was on solid rock,
+in which no footsteps would leave an impression.</p>
+
+<p>&quot;They never brought you up here in a wagon, Mr. Jenks,&quot; decided
+Tom, when he saw how steep the place was.</p>
+
+<p>&quot;I'm inclined to think so myself,&quot; admitted the diamond man.
+&quot;They must have reached the cave from some other way. As a matter
+of fact, I walked some distance after getting out of the vehicle,
+before we got to the cavern. But, even at that, I don't believe
+we came this way.&quot;</p>
+
+<p>&quot;Yet the phantom was here,&quot; persisted Tom, &quot;and I'm convinced
+that the cave is in this neighborhood. It's up to us to find it!&quot;</p>
+
+<p>But they searched the remainder of that day in vain, and as
+night was coming on, they made their way back to the camp. As
+Tom, who was in the lead, approached the tent, he saw something
+black fastened to the entrance.</p>
+
+<p>&quot;Hello!&quot; he cried. &quot;Some one's been here. That wasn't on the
+tent when he left this morning.&quot;</p>
+
+<p>&quot;What is it?&quot; asked Mr. Damon.</p>
+
+<p>&quot;A black piece of paper, written on with white ink,&quot; replied
+the lad. He was reading it, and, as he perused it a look of
+surprise came over his face.</p>
+
+<p>&quot;Listen to this!&quot; called Tom. &quot;It's evidently from the diamond
+makers.&quot;</p>
+
+<p>Holding up the black paper, on which the white writing stood
+out in bold relief Tom read aloud:</p>
+
+
+<p>&quot;Be warned in time! Go back before it is too late! You are near
+to death! Go back!&quot;</p>
+
+
+<p>&quot;Bless my shoelaces!&quot; cried Mr. Damon. &quot;This is getting
+serious.&quot;</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XV_THE_LANDSLIDE" id="CHAPTER_XV_THE_LANDSLIDE" />CHAPTER XV&mdash;THE LANDSLIDE</h2>
+
+
+<p>Gathered about the young inventor, the three men looked at the
+warning. The writing was poor, and it was evident that an attempt
+had been made to disguise it. But there was no misspelling of
+words, and there were no rudely drawn daggers, or bloody hands or
+anything of that sort. In fact, it was a very business-like sort
+of warning.</p>
+
+<p>&quot;Rather odd,&quot; commented Mr. Jenks. &quot;Black paper and white ink.&quot;</p>
+
+<p>&quot;White ink is easy enough to make,&quot; stated Mr. Parker. &quot;I fancy
+they wanted it as conspicuous as possible.&quot;</p>
+
+<p>&quot;Yes,&quot; agreed Tom, &quot;and this warning, together with the antics
+of the thing in white last night, shows that they are aware of
+our presence here, and perhaps know who we are. We will have to
+be on our guard.&quot;</p>
+
+<p>&quot;Do you think that fellow Munson, whom we left in the forest,
+could have gotten here and warned them?&quot; asked Mr. Damon.</p>
+
+<p>&quot;It's possible,&quot; admitted Tom, &quot;but now let's see if the person
+who pinned this warning on our tent took any of our things.&quot;</p>
+
+<p>A hasty examination, however, showed that nothing had been
+disturbed, and Tom and Mr. Damon were soon getting supper ready,
+everyone talking, during the progress of the meal, about the
+events of the day, and the rather weird culmination of it.</p>
+
+<p>&quot;Well, we haven't had a great deal of success&mdash;so far,&quot;
+admitted Tom, as they sat about the fire, in the fast gathering
+dusk. &quot;I think, perhaps, we'd better try on the other side of the
+mountain to-morrow. We've explored this side pretty thoroughly.&quot;</p>
+
+<p>&quot;Good idea,&quot; commented Mr. Jenks. &quot;We'll do it, and move our
+camp. I only hope those fellows don't find our airship and
+destroy it. We'll have a hard time getting back to civilization
+again, if we have to walk all the way.&quot;</p>
+
+<p>This contingency caused Tom some uneasiness. He did not like to
+think that the unscrupulous men might damage the Red Cloud, that
+had been built only after hard labor. But he knew he could
+accomplish nothing by worrying, and he tried to dismiss the
+matter from his mind.</p>
+
+<p>They rather expected to see the thing in white again that
+night, but it did not appear, and morning came without anything
+having disturbed their heavy sleep, for they were tired from the
+day's tramp.</p>
+
+<p>It took them the greater part of the day to make a circuit of
+the base of Phantom Mountain in order to get to a place where a
+sort of trail led upward.</p>
+
+<p>&quot;It's too late to do anything to-night,&quot; decided Tom, as they
+set up the tent. &quot;We'll rest, and start the first thing in the
+morning.&quot;</p>
+
+<p>&quot;And the ghost isn't likely to find us here,&quot; added Mr. Damon.
+&quot;Where are you going, Mr. Parker?&quot; he asked, as he saw the
+scientist tramping a little way up the side of the mountain.</p>
+
+<p>&quot;I am going to make some observations,&quot; was the answer, and no
+one paid any more attention to him for some time. Supper was
+nearly ready when Mr. Parker returned. His face wore a rather
+serious air, and Mr. Damon, noting it, asked laughingly:</p>
+
+<p>&quot;Well, did you discover any volcanoes, that may erupt during
+the night, and scare us to death?&quot;</p>
+
+<p>&quot;No,&quot; replied Mr. Parker, calmly, &quot;but there is every
+indication that we will soon have a terrific electrical storm.
+From a high peak I caught a glimpse of one working this way
+across the mountains.&quot;</p>
+
+<p>&quot;Then we'd better fasten the tent well down,&quot; called Tom. &quot;We
+don't want it to blow away.&quot;</p>
+
+<p>&quot;There will not be much danger from wind,&quot; was Mr. Parker's
+opinion.</p>
+
+<p>&quot;From what then?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;From the discharges of lightning among these mountain peaks,
+which contain so much iron ore. We will be in grave danger.&quot;</p>
+
+<p>The fact that the scientist had not always made correct
+predictions was not now considered by his hearers, and Tom and
+the two men gazed at Mr. Parker in some alarm.</p>
+
+<p>&quot;Is there anything we can do to avoid it?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;The only thing to do would be to leave the mountain,&quot; was the
+answer, &quot;and, as the iron ore extends for miles, we can not get
+out of the danger zone before the storm will reach us. It will be
+here in less than half an hour.&quot;</p>
+
+<p>&quot;Then we'd better have supper,&quot; remarked Tom, practically, &quot;and
+get ready for it. Perhaps it may not be as bad as Mr. Parker
+fears.&quot;</p>
+
+<p>&quot;It will be bad enough,&quot; declared the gloomy scientist, and he
+seemed to find pleasure in his announcement.</p>
+
+<p>The meal was soon over, and Tom busied himself in looking to
+the guy ropes of the tent, for he feared lest there might be wind
+with the storm. That it was coming was evident, for now low
+mutterings of thunder could be heard off toward the west.</p>
+
+<p>Black clouds rapidly obscured the heavens, and the sound of
+thunder increased. Fitful flashes of lightning could be seen
+forking across the sky in jagged chains of purple light.</p>
+
+<p>&quot;It's going to be a heavy storm,&quot; Tom admitted to himself. &quot;I
+hope lightning doesn't strike around here.&quot;</p>
+
+<p>The storm came on rapidly, but there was a curious quietness in
+the air that was more alarming than if a wind had blown. The
+campfire burned steadily, and there was a certain oppressiveness
+in the atmosphere.</p>
+
+<p>It was now quite dark, save when the fitful lightning flashes
+came, and they illuminated the scene brilliantly for a few
+seconds. Then, by contrast, it was blacker than ever.</p>
+
+<p>Suddenly, as Tom was gazing up toward the peak of Phantom
+Mountain, he saw something that caused him to cry out in alarm.
+He pointed upward, and whispered hoarsely:</p>
+
+<p>&quot;The ghost again! There's our friend in white!&quot;</p>
+
+<p>The others looked, and saw the same weird figure that had
+menaced them when they were encamped on the other side of the
+peak.</p>
+
+<p>&quot;They must have followed us,&quot; said Mr. Jenks, in a low voice.</p>
+
+<p>Slowly the figure advanced, It waved the long white arms, as if
+in warning. At times it would be only dimly visible in the
+blackness, then, suddenly it would stand out in bold relief as a
+great flash of fire split the clouds.</p>
+
+<p>The thunder, meanwhile, had been growing louder and sharper,
+indicating the nearer approach of the storm. Each lightning flash
+was followed in a second or two, by a terrific clap. Still there
+was no wind nor rain, and the campfire burned steadily.</p>
+
+<p>All at once there was a crash as if the very mountain had split
+asunder, and the adventurers saw a great ball of purple-bluish
+fire shoot down, as if from some cloud, and strike against the
+side of the crag, not a hundred feet from where stood the ghostly
+figure in white.</p>
+
+<p>&quot;That was a bad one,&quot; cried Mr. Damon, shouting so as to be
+heard above the echoes of the thunderclap.</p>
+
+<p>Almost as he spoke there came another explosion, even louder
+than the one preceding. A great ball of fire, pear shaped, leaped
+for the same spot in the mountain.</p>
+
+<p>&quot;There's a mass of iron ore there!&quot; yelled Mr. Parker. &quot;The
+lightning is attracted to it!&quot;</p>
+
+<p>His voice was swallowed up in the terrific crash that followed,
+and, as there came another flash of the celestial fire, the
+figure in white could be seen hurrying back up the mountain
+trail. Evidently the electrical storm, with lightning bolts
+discharging so close, was too much for the &quot;ghost.&quot;</p>
+
+<p>In another instant it looked as if the whole place about where
+the diamond seekers stood, was a mass of fire. Great forked
+tongues of lightning leaped from the clouds, and seemed to lick
+the ground. There was a rattle and bang of thunder, like the
+firing of a battery of guns. Tom and the others felt themselves
+tingling all over, as if they had hold of an electrical battery,
+and there was a strong smell of sulphur in the air.</p>
+
+<p>&quot;We are in the midst of the storm!&quot; cried Mr. Parker. &quot;We are
+standing on a mass of iron ore! Any minute may be our last!&quot;</p>
+
+<p>But fate had not intended the adventurers for death by
+lightning. Almost as suddenly as it had begun, the discharge of
+the tongues of fire ceased in the immediate vicinity of our
+friends. They stood still&mdash;awed&mdash;not knowing what to do.</p>
+
+<p>Then, once more, came a terrific clap! A great mass of fire,
+like some red-hot ingot from a foundry, was hurled through the
+air, straight at the face of the mountain, and at the spot where
+the figure in white had stood but a few minutes before.</p>
+
+<p>Instantly the earth trembled, as it had at Earthquake Island,
+but it was not the same. It was over in a few seconds. Then, as
+the diamond seekers looked, they saw in the glare of a score of
+lightning flashes that followed the one great clap, the whole
+side of the mountain slip away, and go crashing into the valley
+below.</p>
+
+<p>&quot;A landslide!&quot; cried Mr. Parker. &quot;That is the landslide which I
+predicted! The lightning bolt has split Phantom Mountain!&quot;</p>
+

+
+
+<p>For a time the roiling, slipping, sliding and tumbling of the
+mass of earth and stones, down the side of the mountain,
+effectually drowned all other sounds. Even the thunder was
+stilled, and though Tom and his companions called to one another
+in terror, their voices could not rise above that terrific
+tumult.</p>
+
+<p>Finally, when they found that the direction of the slide was
+away from their tent, and that they were not likely to be
+engulfed, they grew more calm.</p>
+
+<p>Gradually the noise subsided. The great boulders had rolled to
+the bottom of the valley, and now only a mass of earth and stones
+was sliding down. Even this stopped in about five minutes, and,
+as though satisfied with what it had done, the electrical storm
+passed. Not a drop of rain had fallen.</p>
+
+<p>&quot;Bless my shirt studs!&quot; exclaimed Mr. Damon, who was the first
+to speak after the din had quieted. &quot;Bless my soul! But that was
+awful!&quot;</p>
+
+<p>&quot;It was just what I expected,&quot; said Mr. Parker, calmly. &quot;I
+knew, from my observations, that we were in a region where
+landslides and terrific electrical storms may be expected at any
+time. I fully looked for this.&quot;</p>
+
+<p>&quot;Well,&quot; remarked Mr. Jenks, rather sarcastically, &quot;I hope it
+came up to your expectations, Mr. Parker.&quot;</p>
+
+<p>&quot;Oh, fully,&quot; was the answer, &quot;though I wish it could have
+happened in daylight, so that I could better have observed
+certain phenomena regarding the landslide. They are very
+interesting.&quot;</p>
+
+<p>&quot;At a distance,&quot; admitted Tom, with a laugh of relief. &quot;Well,
+I'm glad it's over, though we'll have to wait until morning to
+see what damage has been done. Lucky we weren't struck by
+lightning. I never saw such bolts!&quot;</p>
+
+<p>&quot;Me, either!&quot; declared Mr. Damon. &quot;This mountain seems to
+attract them.&quot;</p>
+
+<p>&quot;It is like a magnet,&quot; said Mr. Parker. &quot;I think I shall be
+able to make some fine observations here.&quot;</p>
+
+<p>&quot;If we live through it,&quot; murmured Mr. Jenks.</p>
+
+<p>They watched the play of lightning about a distant bank of
+clouds, but the storm was now far away, only a faint rumbling of
+thunder being heard.</p>
+
+<p>&quot;I'm wondering what happened to the phantom,&quot; said Tom, after a
+pause. &quot;Seems to me he was right in that track of the storm.&quot;</p>
+
+<p>&quot;Do you think it was a 'he'?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;I think we'll find that it's some sort of a man,&quot; answered the
+young inventor. &quot;We may find out very soon, now. I've changed my
+theory about the ghost being reflections of light.&quot;</p>
+
+<p>&quot;How's that?&quot; Mr. Damon wanted to know.</p>
+
+<p>&quot;Well, I think we are on the side of Phantom Mountain where the
+diamond cave is,&quot; went on the lad. &quot;The fact that the phantom
+appeared here, soon after we arrived, shows that the men kept
+close track of our movements. It also shows, I think, that the
+phantom did not have to travel far to be on the spot, whereas we
+had to make quite a trip to get around the base of the mountain.
+I think the cave is up there,&quot; and Tom pointed toward the spot
+where the weird figure had been last seen, before the storm drove
+it back.</p>
+
+<p>&quot;There may be two phantoms,&quot; suggested Mr. Jenks. &quot;They may
+keep one on this side of the mountain, and one on the other, to
+warn intruders away.</p>
+
+<p>&quot;It's possible,&quot; admitted Tom. &quot;Well, we'll see how things look
+in the morning, when we'll take up our march again, and go up the
+mountain. We'll reach the top, if possible, which we couldn't do
+from the other side, as it was too steep.&quot;</p>
+
+<p>&quot;I hope we shall be able to go forward in the morning,&quot; came
+from Mr. Jenks.</p>
+
+<p>&quot;What do you mean?&quot; asked the lad, struck by a peculiar
+significance in the diamond man's tones.</p>
+
+<p>&quot;Why, that landslide may have opened a great gully in the side
+of Phantom Mountain, which will prevent us from passing. It was a
+terrific lot of earth and stones that slid away,&quot; answered Mr.
+Jenks.</p>
+
+<p>&quot;It certainly was,&quot; agreed Mr. Parker. &quot;I would not be
+surprised if the mountain was half destroyed, and it may be that
+the diamond cave no longer exists.&quot;</p>
+
+<p>&quot;Not very cheerful, to say the least,&quot; murmured Mr. Jenks to
+Tom, and, as it was getting quite chilly, following the storm,
+they went inside the tent.</p>
+
+<p>Tom could hardly wait for daylight, to get up and see what
+havoc the landslide had wrought. As soon as the first faint flush
+of dawn showed over the eastern peaks, he hurried from the tent.
+Mr. Damon heard him arise, and followed.</p>
+
+<p>A curious scene met their eyes. All about were great rocks rent
+and torn by the awful power of the lightning. The fronts of the
+stone cliffs were scarred and burned by the electrical fire, and
+fantastic markings, grotesque faces, and leering animals seemed
+to have been drawn by some gigantic artist who used a bolt from
+heaven for his brush.</p>
+
+<p>But the eyes of Tom and Mr. Damon took all this in at a glance,
+and then their gaze went forward to where the avalanche had torn
+away a great part of the mountain.</p>
+
+<p>&quot;Whew! I should say it was a landslide!&quot; cried Tom.</p>
+
+<p>&quot;Bless my wishbone, yes!&quot; agreed Mr. Damon.</p>
+
+<p>Below them, in the valley, lay piled immense masses of earth
+and stones. Boulders were heaped up on boulders, and rocks upon
+rocks, being tossed about in heaps, strung about in long ridges,
+and swirled about in curves, as though some cyclone had toyed
+with them after the lightning flash had tossed them there.</p>
+
+<p>&quot;But the mountain isn't half gone,&quot; said Tom, as his eyes took
+in what was left of the phantom berg. &quot;I guess it will take a few
+more bolts like that one, to put this hill out of business.&quot;</p>
+
+<p>Though the landslide had been a great one, the larger part of
+the mountain still stood. An immense slice had been taken from
+one side, but the summit was untouched.</p>
+
+<p>&quot;And there's where the diamond cave is!&quot; cried Tom, pointing to
+it.</p>
+
+<p>&quot;I think so myself,&quot; agreed Mr. Jenks, who came from the tent
+at that moment, and joined the lad and Mr. Damon. &quot;I think we
+shall find the cave somewhere up there. We must start for it, as
+soon as we have eaten, and we may reach it by night.&quot;</p>
+
+<p>The three stood gazing up toward the summit of the great
+mountain. Suddenly, as the sun rose higher in the heavens, it
+sent a shaft of rosy light on the face of the berg that had been
+scarred by the landslide. Tom Swift uttered an exclamation, and
+pointed at something.</p>
+
+<p>&quot;See!&quot; he cried. &quot;Look where the trail is&mdash;the trail down which
+the phantom must have come. It is on the edge of a cliff now!&quot;</p>
+
+<p>They looked, and saw that this was so. The increasing light had
+just revealed it to them. When the lightning bolt had torn away a
+great portion of the mountain it had cut sheer down for a great
+depth and when the earth and stones fell away they left a narrow
+pathway, winding around the mountain, but so near the edge of a
+great chasm, that there was room but for one person at a time to
+walk on that footway. The uncertain trail up Phantom Mountain had
+all but been destroyed.</p>
+
+<p>&quot;The way up to the peak is by that path, now,&quot; spoke Tom, in a
+low voice.</p>
+
+<p>&quot;Bless my soul!&quot; cried Mr. Damon. &quot;It's as much as a man's life
+is worth to attempt it. If he got dizzy, he'd topple over, and
+fall a thousand feet. Dare we risk it?&quot;</p>
+
+<p>&quot;It's the only way to get up,&quot; went on Tom. &quot;It's either that
+way, or not at all. We've tried the other side without success.
+We must go up this way&mdash;or turn back.&quot;</p>
+
+<p>&quot;Then we'll go up!&quot; cried Mr. Jenks. &quot;It may not be as
+dangerous as it looks from here.&quot;</p>
+
+<p>But it was even more dangerous than it appeared, when they went
+part way up it after a hasty breakfast. The trail was a mere
+ledge of rock now, and in some places, to get around a projecting
+edge of the mountain, they had to stand with their backs to the
+dizzy depths at their feet, and with both arms outstretched work
+their way around to where the trail was wider.</p>
+
+<p>&quot;Shall we risk it?&quot; asked Tom, when they had tried the way, and
+found it so dangerous. &quot;We can't take anything with us&mdash;even our
+guns, for we couldn't carry them, and if we reach the month of
+the cave, and find those men there&mdash;&quot;</p>
+
+<p>He paused significantly. The adventurers looked at one another.
+The search for the diamond makers was becoming more and more
+dangerous.</p>
+
+<p>&quot;I say let's go on!&quot; decided Mr. Damon, suddenly. &quot;We want to
+locate that cave, first of all. Perhaps, when we do find it, we
+may see some easier way of getting to it than this. And if those
+diamond makers do attack us&mdash;well, I don't believe they'll shoot
+defenseless men, and they may listen to reason, and give Mr.
+Jenks his rights&mdash;tell him how to make diamonds in return for the
+money he gave them.&quot;</p>
+
+<p>&quot;I don't believe those scoundrels will listen to reason,&quot;
+replied the diamond man, &quot;but I agree with Mr. Damon that we
+ought to go on. We may find some other means of reaching the
+cave&mdash;if we can discover it, and we'll take a chance with the
+men.&quot;</p>
+
+<p>&quot;Forward it is, then!&quot; cried Tom. &quot;I have a revolver, and I can
+supply one of you gentlemen with another. They may come in useful
+in an emergency. Let's go back to camp, take a little lunch in
+our pockets, and try to scale the mountain.&quot;</p>
+
+<p>They were soon on their way up the dizzy path once more, and,
+as they advanced, they found it growing more and more dangerous.
+In some places they found it almost impossible to get around
+certain corners, where there was barely room for their feet. As
+Tom remarked grimly, a fat man never could have done it.
+Fortunately they were all comparatively thin, for their hard
+work, and not too abundant food, since they had left the airship,
+had reduced their weight.</p>
+
+<p>Up and up they went, higher and higher, sometimes finding the
+path wide enough for two to walk abreast, and again seeing it
+narrow almost to a ribbon. They hardly dared look down into the
+chasm at their left&mdash;a chasm filled, in part, with the rocks and
+boulders tossed into it by the lightning bolt.</p>
+
+<p>Tom was in the lead, and had just made a dangerous turn around
+a shoulder of rock&mdash;one of those places where he had to extend
+both arms, and fairly hug the cliff before he could get around.</p>
+
+<p>But, when he had made it, and found himself on a broad pathway,
+cut in the living rock, he gave a great shout&mdash;a shout that
+caused his companions to hasten to his side. They found the young
+inventor pointing to a clump of bushes and small trees.</p>
+
+<p>But it was not the shrubbery that Tom desired to call to their
+attention. They saw that in an instant, for, dimly seen through
+the leaves, was something black, and, as they looked more
+closely, they saw that it was a great hole in the side of the
+mountain&mdash;a vast cavern, opening like a tunnel.</p>
+
+<p>&quot;The cave! The cave!&quot; cried Tom. &quot;The diamond makers' cave!&quot;</p>
+
+<p>Hardly had he spoken than two men, each one carrying a gun,
+showed themselves in the mouth of the cavern, and, instant later
+they both ran toward the little party of adventurers.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XVII_THE_PHANTOM_CAPTURED" id="CHAPTER_XVII_THE_PHANTOM_CAPTURED" />CHAPTER XVII&mdash;THE PHANTOM CAPTURED</h2>
+
+
+<p>Surprise held Tom and his friends almost spellbound for the
+moment. The young inventor's hand went toward the pocket where he
+carried his revolver. Mr. Jenks, who had the only other weapon,
+sought to draw it, but he was stopped by a gesture of one of the
+two men with guns.</p>
+
+<p>&quot;Hold on, strangers!&quot; the man cried. &quot;I know what you're up to!
+Better not try to draw anything&mdash;it might not be healthy. Now,
+then, who are you, and what do you want?&quot;</p>
+
+<p>The question came rather as a surprise, at least to Tom and Mr.
+Jenks. They had taken it for granted that these men&mdash;if they were
+the diamond makers&mdash;would know Mr. Jenks, and guess at his errand
+in coming back to Phantom Mountain. But, it seemed, that they
+took them all for casual strangers.</p>
+
+<p>No one answered for a moment. Tom caught the eye of Mr. Jenks,
+and there was a look of hope in it. If ever there was a time for
+strategy, it was now. Evidently Munson, the stowaway on the
+airship, had not yet been able to send a warning to his
+confederates. And neither of the two men recognized Mr. Jenks as
+the man who had been defrauded of his rights. It might be
+possible to conceal the real object of the adventurers until they
+had time to formulate a plan of action.</p>
+
+<p>&quot;Well,&quot; exclaimed the man with the gun, impatiently, &quot;I ask you
+folks a question. What do you want?&quot;</p>
+
+<p>Fortunately, neither Mr. Damon nor Mr. Parker replied. The
+former because he deferred to Tom and Mr. Jenks, and the
+scientist because he was busy inspecting some curious rocks he
+picked up. As it turned out this was the luckiest thing he could
+have done. It lent color to what Mr. Jenks said a moment later.</p>
+
+<p>&quot;What are you doing up here?&quot; demanded the man again. &quot;Don't
+you know this is private property?&quot;</p>
+
+<p>&quot;We&mdash;we were just looking around,&quot; answered Mr. Jenks, which
+was true enough; as far as it went.</p>
+
+<p>&quot;Prospecting,&quot; added Tom.</p>
+
+<p>&quot;After gold?&quot; demanded the second man, suspiciously.</p>
+
+<p>&quot;We'd be glad to find some,&quot; retorted the lad. At that moment
+Mr. Parker began breaking off bits of rock with a small
+geologist's hammer which he carried. The men with the guns looked
+at him.</p>
+
+<p>&quot;So you think you'll find gold up here?&quot; asked the one who had
+first spoken.</p>
+
+<p>&quot;Is there any?&quot; inquired Tom, trying to make his voice sound
+eager.</p>
+
+<p>&quot;Nary a bit, strangers,&quot; was the answer, and the two men
+laughed heartily. &quot;Now, we don't want to seem harsh,&quot; went on the
+man who seemed to be the spokesman, &quot;but you'd better get away
+from here. This is private ground, and dangerous too&mdash;how'd you
+ever get up the trail&mdash;we heard it was destroyed.&quot;</p>
+
+<p>&quot;There is still a narrow path,&quot; said Mr. Jenks. &quot;We came up
+that&mdash;the lightning and landslide haven't left much of it,
+though.&quot;</p>
+
+<p>Mr. Parker looked quickly up from the rocks at which he was
+tapping with his small hammer. &quot;You have terrific lightning up
+here,&quot; he said. &quot;I am much interested in it, from a scientific
+standpoint. I predict that some day the entire mountain will be
+destroyed by a blast from the sky.&quot;</p>
+
+<p>&quot;I hope it won't be right away,&quot; spoke one of the men. &quot;Now I
+guess you folks had better be leaving while there's a path left
+to go down by.&quot;</p>
+
+<p>&quot;Might I ask,&quot; broke in Mr. Parker, as calmly as though he was
+lecturing to a class of students, &quot;might I ask if you have
+noticed any peculiar effect of the lightning up here on the
+summit of the mountain? Does it fuse and melt rocks, so to
+speak?&quot;</p>
+
+<p>&quot;What's that?&quot; cried the spokesman, with a sudden flash of
+anger. The two men looked at each other.</p>
+
+<p>&quot;I wanted to know, merely for scientific reasons, whether the
+lightning up here ever melted rocks?&quot; repeated Mr. Jenks.</p>
+
+<p>&quot;Well, whether it's for scientific reasons or for any other,
+I'm not going to answer you!&quot; snapped the man. &quot;It's none of your
+affair what the lightning does up here. Now you'd all better
+'vamoose'&mdash;clear out!&quot;</p>
+
+<p>&quot;All right&mdash;we'll go,&quot; said Tom, quickly, at the same time
+motioning to Mr. Jenks to agree with him. The eyes of the young
+inventor were roving about. He saw what looked like a second
+trail, leading down the mountain, from the far side of the cave.
+He was convinced now that there was another way to get to it.
+Possibly they might find it. At any rate nothing more could be
+done now. They must go back, for the cavern was too well guarded
+to attempt to enter it by force&mdash;at least just yet.</p>
+
+<p>&quot;Yes, we'll go back,&quot; assented Mr. Jenks.</p>
+
+<p>Mr. Parker was tapping away at the rocks. He looked toward the
+black mouth of the big cave. On what corresponded to the roof of
+it, some distance back from the entrance, he saw a slender metal
+rod sticking up into the air.</p>
+
+<p>&quot;May I ask if that's a lightning rod?&quot; he inquired innocently.
+&quot;If it is, I should like to ask about its action in a mountain
+that is so impregnated with iron ore.</p>
+
+<p>&quot;You may ask until you get tired!&quot; cried the spokesman, again
+showing unreasoning anger, &quot;but you'll get no answer from us. Now
+get away from here before we do something desperate. You're on
+private ground and you're not wanted. Clear out while you have
+the chance.&quot;</p>
+
+<p>There was no help for it. Slowly our friends turned and began
+to go down the dangerous trail. They were soon out of sight of
+the two men who stood before the cave, with their guns ready, but
+neither Tom nor any of his companions spoke for some time.</p>
+
+<p>When they had rounded one of the most dangerous turns the young
+inventor sat down to rest, an example followed by the others.</p>
+
+<p>&quot;Well,&quot; asked Tom, &quot;do you think those are some of the diamond
+makers, Mr. Jenks?&quot;</p>
+
+<p>&quot;I certainly do, though I never saw those two men before. If I
+could once get inside the cave, I could tell whether or not it
+was the one where I was practically held a prisoner. But I'm sure
+it is. I know some of the men used to go off every day with guns,
+and not come back until night. I have no doubt they were on
+guard, just as these two are. And, also, I think I heard them
+speak of a second entrance to the cavern. The one we just saw may
+not be the main one, through which I was taken.&quot;</p>
+
+<p>&quot;I believe we are on the right track,&quot; ventured Mr. Damon, &quot;but
+we will either have to go up there after dark, which will be
+risky, on account of the narrow trail, or else we will have to
+find some other path.&quot;</p>
+
+<p>&quot;The last would be better,&quot; spoke Tom.</p>
+
+<p>&quot;That rod of metal sticking up on top of the cave interested
+me,&quot; said the scientist. &quot;Did you hear anything of that when you
+were here before, Mr. Jenks?&quot;</p>
+
+<p>&quot;No. Probably that is only a lightning rod, or it may be a
+staff for a signal flag. But what surprises me is that those men
+didn't suspect that we were seeking to discover their secret.
+They took us for ordinary prospectors.&quot;</p>
+
+<p>&quot;So much the better,&quot; remarked Tom. &quot;We have a chance now of
+getting inside that cave. But we will have to go back to camp,
+and make other plans. And we must hurry, or it will be dark
+before we get there.&quot;</p>
+
+<p>They hastened their steps, pausing only briefly to eat some of
+the lunch they had brought along, and to drink from a spring that
+bubbled from the side of the mountain. It was getting dusk when
+they got back to their tent. They found nothing disturbed.</p>
+
+<p>&quot;I wonder if we'll see that phantom again to-night?&quot; ventured
+Tom, as they were sitting about the campfire a little later.</p>
+
+<p>&quot;Probably not,&quot; remarked Mr. Jenks. &quot;I don't believe the ghost
+will venture down the dangerous trail after dark, and the gang
+may think that the warning given us by the two men on guard at
+the cave will be sufficient. But if we don't leave here by
+to-morrow I think we will have another visit from the thing in
+white.&quot;</p>
+
+<p>It was about an hour after this when Tom was collecting some
+wood in a pile nearer the fire, so as to have it ready to throw
+on, in case there was any alarm in the night, that he happened to
+look up toward the summit of the mountain. A slight noise, as of
+loose stones rolling down, attracted his attention, and, at
+first, he feared lest another landslide was beginning, but a
+moment later he saw what caused it.</p>
+
+<p>There, advancing down the steep and dangerous trail was the
+figure in white&mdash;the phantom. Instantly a daring plan came into
+Tom's head. Dropping the wood softly, he moved back out of the
+glare of the fire.</p>
+
+<p>&quot;Mr. Jenks!&quot; he called in a whisper.</p>
+
+<p>The diamond man, who was behind the tent, came toward Tom.</p>
+
+<p>&quot;What is it?&quot; he asked. Then, as he saw the ghostly visitor, he
+added: &quot;Oh&mdash;the phantom again! What's it up to?&quot;</p>
+
+<p>&quot;The same thing,&quot; replied Tom, &quot;but it won't do it long, if my
+plan succeeds.&quot;</p>
+
+<p>&quot;What plan is that, Tom?&quot;</p>
+
+<p>&quot;I'm going to try to capture that&mdash;that man&mdash;or whatever it is.
+Will you help?&quot;</p>
+
+<p>&quot;Surely!&quot;</p>
+
+<p>&quot;Then let's work around behind it, while Mr. Damon and Mr.
+Parker come up from in front. We'll solve this part of the
+mystery, anyhow, if it's possible!&quot;</p>
+
+<p>The two other men were soon told of the plan. Meanwhile the
+thing in white had advanced slowly, until within a few hundred
+feet of the camp. They could see now that it was no shaft of
+light, but some white body, shaped like a tall, thin man, draped
+in a white garment. The long arms waved to and fro. There was no
+semblance of a head.</p>
+
+<p>&quot;You and Mr. Parker go right toward it, slowly, Mr. Damon,&quot;
+advised Tom. &quot;Mr. Jenks and I will make a circle, and get in
+back. Then, if it's anything alive we'll have it.&quot;</p>
+
+<p>The &quot;ghost&quot; continued to advance. Tom and the diamond man stole
+off to one side, their buckskin moccasins making no sound. Mr.
+Damon and the scientist went boldly forward.</p>
+
+<p>This movement appeared to disconcert the spirit. It halted,
+waved the arms with greater vigor than before, and seemed to
+indicate to the adventurers that it was dangerous to advance. But
+Mr. Damon and Mr. Parker kept on. They wanted to give Tom and Mr.
+Jenks time enough to make the circuit.</p>
+
+<p>Suddenly the stillness of the night was broken by a low
+whistle. It was Tom's signal that he and Mr. Jenks were ready.</p>
+
+<p>&quot;Come on! Run!&quot; cried Mr. Damon.</p>
+
+<p>The scientist and the eccentric man leaped forward.</p>
+
+<p>The &quot;ghost&quot; heard the whistle, and heard the spoken words. The
+thing in white hesitated a moment, and then raised one arm. There
+was a flash of lire, and a loud report.</p>
+
+<p>&quot;He's firing in the air!&quot; cried Tom. &quot;Come on, we have him
+now!&quot;</p>
+
+<p>Undaunted by the display of firearms, Mr. Damon and Mr. Parker
+kept on. They could hear Tom and Mr. Jenks running up in back of
+the figure. The latter also heard this, and suddenly turned.
+Caught between the two forces of our friends, the &quot;ghost&quot; was at
+a loss what to do.</p>
+
+<p>The next instant Tom, who had distanced Mr. Jenks, made a
+flying tackle for the figure in white, and caught it around the
+legs. Very substantial legs they were, too, Tom felt&mdash;the legs of
+a man.</p>
+
+<p>&quot;Wow!&quot; yelled the &quot;ghost,&quot; as he went down in a heap, the
+revolver falling from his hand.</p>
+
+<p>&quot;Come on!&quot; cried Tom. &quot;I have him!&quot;</p>
+
+<p>His friends rushed to his aid. There was a confused mass of
+dark bodies, arms and legs mingled with something tall and thin,
+all in white. Suddenly the moon came from behind a cloud and they
+could see what they had captured&mdash;for captured the phantom was.</p>
+
+<p>It proved to be a rather small man, who wore upon his shoulders
+a framework of wood, over which some white cloth was draped. It
+had fallen off him when Tom made that tackle.</p>
+
+<p>&quot;Well,&quot; remarked the young inventor, as he sat on the
+struggling man's chest. &quot;I guess we've got you.&quot;</p>
+
+<p>&quot;I rather guess you have, stranger,&quot; was the cool reply.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XVIII_BILL_RENSHAW_WILL_HELP" id="CHAPTER_XVIII_BILL_RENSHAW_WILL_HELP" />CHAPTER XVIII&mdash;BILL RENSHAW WILL HELP</h2>
+
+
+<p>They were all panting from the exertion of the run up the
+mountain and the contest with the phantom&mdash;a phantom no longer&mdash;though,
+truth to tell, the struggle was not nearly so fierce as
+Tom had expected. He thought the &quot;ghost&quot; would put up a stiff
+fight.</p>
+
+<p>&quot;Got any ropes to tie him with?&quot; asked Mr. Damon, who was
+helping Tom hold the man down.</p>
+
+<p>&quot;Ropes? You aren't going to tie me up are you, strangers?&quot;
+asked the captive.</p>
+
+<p>&quot;That's what we are!&quot; exclaimed Mr. Jenks. &quot;We've had trouble
+enough in this matter, and if I've got one of the gang, perhaps I
+can get some of the others, and have my rights. So tie him up,
+Tom, and we'll take him to camp.</p>
+
+<p>&quot;Oh, you needn't go to all that trouble, strangers,&quot; went on
+the man, calmly. &quot;If one of you will get off my chest, and the
+other gentleman ease up on my stomach a bit, I'll walk wherever
+you want me, and not make any trouble. I haven't got a gun.&quot;</p>
+
+<p>&quot;Bless my gloves! But you're a cool one,&quot; commented Mr. Damon,
+as he complied with the man's request, and got up from his
+stomach. &quot;But look out for him, Tom. He had a gun, for he fired
+it in the air.&quot;</p>
+
+<p>&quot;He hasn't it now,&quot; answered the young inventor. &quot;I knocked it
+from his hand when I leaped for him.&quot;</p>
+
+<p>&quot;That's what you did,&quot; assented the man, as he got up, while
+Tom kept a tight hold of him, as did Mr. Jenks. &quot;What kind of a
+grizzly bear hug do you call that, anyhow, that you gave me?&quot;</p>
+
+<p>&quot;That was a football tackle,&quot; explained Tom.</p>
+
+<p>&quot;I allers heard that was a dangerous game!&quot; remarked the former
+phantom simply. &quot;Well, now you've got me, what are you going to
+do with me?&quot;</p>
+
+<p>&quot;Take you where we can have a good look at you,&quot; replied Mr.
+Jenks, as he kicked aside the wooden framework, and the sheet
+which had made the &quot;ghost&quot; appear so tall. &quot;So this is how you
+worked it; eh?&quot;</p>
+
+<p>&quot;Yep. That was the 'haunt' stranger. I made it myself, and it
+worked all right until you folks come along. I rather suspicioned
+from the first, when I played the trick over on 'tother side of
+the mountain, that you wouldn't be so easy to fool as most
+prospectors are.&quot;</p>
+
+<p>&quot;Oh, so you're the only ghost then?&quot; asked Tom.</p>
+
+<p>&quot;I'm the only one.&quot;</p>
+
+<p>By this time they had reached the camp. Tom threw some light
+logs on the fire, which blazed up brightly. As the flames
+illuminated the face of their captive, Mr. Jenks looked at him,
+and cried out:</p>
+
+<p>&quot;Why it's Bill Renshaw!&quot;</p>
+
+<p>&quot;That's me,&quot; admitted the man who had played the part of the
+phantom, &quot;and thunder-turtles! if it ain't Mr. Jenks who was once
+in the diamond cave with us. Whatever happened to you? I never
+heard. The others said you got tired and went away.&quot;</p>
+
+<p>&quot;They took me away&mdash;defrauded me of my rights!&quot; declared Mr.
+Jenks, bitterly. &quot;But I'll get them back! To think of Bill
+Renshaw playing the part of a ghost!&quot;</p>
+
+<p>&quot;They made me do it,&quot; went on the man, somewhat dejectedly. &quot;I
+wanted to be at work in the cave, but they wouldn't let me.&quot;</p>
+
+<p>&quot;Is this man one of the diamond makers?&quot; asked Tom, in great
+surprise.</p>
+
+<p>&quot;He is&mdash;one of the helpers, though I don't believe he knows the
+secret of making the gems,&quot; explained Mr. Jenks. &quot;He was one of
+the men in the cave when I was there before, and he and I struck
+up quite a friendship; didn't we, Renshaw?&quot;</p>
+
+<p>&quot;That's what, and there ain't no reason why we can't be friends
+now; that is unless you hold a grudge against me for firing at
+you. But I only shot in the air, to scare you away. Them's my
+instructions. I'm supposed to be on guard, and scare away
+strangers. I'm tired of the work, too, for I don't get my share,
+and those other fellows, in the cave, get all the money from the
+diamonds.&quot;</p>
+
+<p>Tom Swift uttered an exclamation. A sudden plan had come to
+him. Quickly he whispered to Mr. Jenks:</p>
+
+<p>&quot;Make a friend of this man if possible. He evidently is
+dissatisfied. Offer him a sum to show us another way into the
+cave, and we may yet discover the secret of the diamond makers.&quot;</p>
+
+<p>&quot;I will,&quot; declared Mr. Jenks, quietly. Then, turning to
+Renshaw, he added:</p>
+
+<p>&quot;Bill, come over here. I want to have a talk with you. Perhaps
+it will be to our mutual advantage.&quot;</p>
+
+<p>He led the former phantom to one side, and for some time
+conversed earnestly with him. Mr. Jenks told the story of how he
+had been deceived by Folwell and the others who were at the head
+of the gang of diamond makers. The rich man related how they had
+taken his money, and, after promising to disclose the secret
+process to him, had broken faith, and had drugged him, afterward
+taking him out of the cave.</p>
+
+<p>&quot;I want only my rights, and that for which I paid,&quot; concluded
+Mr. Jenks. &quot;Now, I gather that these men haven't treated you
+altogether fairly, Bill.&quot;</p>
+
+<p>&quot;Indeed they haven't. I helped 'em to the best of my ability,
+and all I get out of it is to stay out on this lonely side of the
+mountain, and play ghost. They owe me money, too, and they won't
+pay me, either, though they have lots, for they sold some
+diamonds lately.&quot;</p>
+
+<p>&quot;Then they are still making diamonds?&quot; asked Mr. Jenks,
+eagerly. &quot;Have you seen them? Do you know the secret?&quot;</p>
+
+<p>&quot;No, I don't know it, for they won't let me in on it. I'm
+always sent out of the cave just before they make the gems. But I
+know they've made some lately, and have sold 'em. I want my
+share.&quot;</p>
+
+<p>&quot;Look here!&quot; exclaimed Mr. Jenks, quickly, wishing to strike
+while the iron was hot. &quot;I'll make you a proposition. Show us how
+to get into that cave, unknown to the diamond makers, and I'll
+pay you twice what they agreed to. Is it a bargain?&quot;</p>
+
+<p>Bill Renshaw considered a moment. Then he thrust out his hand,
+clasped that of Mr. Jenks, and exclaimed:</p>
+
+<p>&quot;It is. I'll take you into the cave by an entrance that's
+seldom used. There are four ways to get in. The one where the two
+men drove you back is the rear one. The front one is on the other
+side of the mountain, but it's so well concealed that you'd never
+find it. But I can take you to one where you can get in, and
+those fellows will never know it. And, what's more, I'll help you
+if it comes to a fight!&quot;</p>
+
+<p>&quot;Good!&quot; exclaimed Mr. Jenks. &quot;I think we'll discover the secret
+of the diamond makers this time,&quot; and he went to tell the others
+of the success of his talk. Bill Renshaw had been converted from
+an enemy into a friend, and the former phantom was now ready to
+lead Tom and the others into the secret cave.</p>
+
+<p>&quot;We'll start in the morning,&quot; decided Mr. Jenks, who, after
+many disappointments, at last saw success ahead of him.</p>

+
+
+<p>Tom Swift was up at break of day, and the others were not far
+behind him.</p>
+
+<p>&quot;Now for the secret cave!&quot; cried the young inventor as he gazed
+up the mountain, in the interior of which the mysterious band of
+men were making the diamonds.</p>
+
+<p>&quot;Have you made any plans, Bill?&quot; asked Mr. Jenks of the former
+phantom, who had cast his lot in with the adventurers. &quot;What will
+be the best course for us to follow?&quot;</p>
+
+<p>&quot;You just leave it to me, Mr. Jenks,&quot; was the answer. &quot;I'll get
+you into the cave, and those fellows, who, I believe, are trying
+to do me out of my rights, as they did you out of yours, will
+never know a thing about it.&quot;</p>
+
+<p>&quot;Bless my finger-nails!&quot; cried Mr. Damon. &quot;That will be great!&quot;
+We can get in the cave, and watch them make the diamonds at our
+leisure.&quot;</p>
+
+<p>&quot;They don't make them every day,&quot; explained Renshaw. &quot;It seems
+they have to wait for certain occasions. Mostly they make the
+diamonds when there's a big storm.&quot;</p>
+
+<p>&quot;A big storm&quot; asked the scientist with a sudden show of
+interest. &quot;Do you mean one of those electrical storms, such as we
+had the other night?&quot;</p>
+
+<p>&quot;That's it, Mr. Parker, though why they wait until there's a
+storm is more than I can tell.&quot;</p>
+
+<p>&quot;Perhaps they know that on such occasions no one will venture
+up the mountain,&quot; spoke Mr. Damon.</p>
+
+<p>&quot;No, it isn't that,&quot; declared the scientist. &quot;I think I am on
+the track of a great scientific discovery, and I will soon be
+able to make observations that will confirm it.&quot;</p>
+
+<p>&quot;Well, I'm going to make an observation right now,&quot; said Tom,
+with a laugh. &quot;I'm going to see what there is for breakfast.&quot;</p>
+
+<p>&quot;And that reminds me,&quot; came from Mr. Jenks, &quot;shall we move our
+camp, Bill, and take the tent with us to the cave?&quot;</p>
+
+<p>&quot;I hardly think so,&quot; was the answer. &quot;I think the best plan
+would be to conceal the tent somewhere around here, in case you
+might need it again. You can also store what food you have left.&quot;</p>
+
+<p>&quot;But, bless my appetite, we don't want to starve in that
+diamond cave!&quot; objected Mr. Damon.</p>
+
+<p>&quot;I'll see that you don't,&quot; declared Bill Renshaw. &quot;I'll take
+you in there, unbeknownst to those fellows, and I'll provide you
+with plenty of food and water. You see the cave is so big that
+there are some parts they never visit.&quot;</p>
+
+<p>&quot;And we can stay in one of those parts, and eat?&quot; asked Tom.</p>
+
+<p>&quot;Sure,&quot; answered Bill.</p>
+
+<p>&quot;And watch the diamond makers at work?&quot; asked Mr. Jenks.</p>
+
+<p>&quot;That's it,&quot; replied the former phantom.</p>
+
+<p>&quot;Then the sooner we get started the better,&quot; remarked Mr.
+Damon. Mr. Parker said nothing. He appeared to be thinking
+deeply, and was tapping at some rocks with his little hammer.</p>
+
+<p>The advice of Bill Renshaw was followed, and the tent, and what
+food remained, was concealed in the bushes, with rocks piled over
+to keep away prowling animals. Then they started for the secret
+cave.</p>
+
+<p>The man who played the part of a ghost picked up the framework
+and white cloth that had formed his disguise.</p>
+
+<p>&quot;I'll still have to use this,&quot; he explained, &quot;for I don't want
+those fellows to know that I'm helping you. I'll continue to play
+the spirit of the mountain, but there won't be much need of it. I
+don't think any more people will come prospecting out here.&quot;</p>
+
+<p>&quot;Have you heard of the arrival of Farley Munson?&quot; asked Tom, as
+he related the facts about the stowaway.</p>
+
+<p>&quot;He hadn't arrived up to a day or so ago,&quot; answered Bill. &quot;I
+guess he's still traveling. Farley is one of the heads of the
+gang,&quot; he added, &quot;and a dangerous man.&quot;</p>
+
+<p>As Bill led the way toward the cave, taking a route that the
+adventurers had never suspected led to it, he explained that the
+cavern was a large one, capable of holding an army.</p>
+
+<p>&quot;But there's only a small part of it used by the diamond
+makers,&quot; he added. &quot;They work in a small recess, near the summit
+of the mountain. The little cave, where I'm going to take you,
+opens off from it by a long passage. And, except that you'll be
+pretty much in the dark, you'll be quite comfortable. There are
+tables, chairs, and some bunks in the place. I can get you some
+lights, and plenty of food.&quot;</p>
+
+<p>&quot;But, if you are seen taking away food, won't the others
+suspect something?&quot; asked Tom.</p>
+
+<p>&quot;I do pretty much as I please,&quot; said Bill. &quot;I go and come when
+I like. All I'm supposed to do is to watch my two sides of the
+mountain, play the ghost, and give warning when any one is
+coming. Sometimes I leave black and white messages, like the one
+I put on your tent. Those fellows fix 'em up for me. I've told
+'em about you, though I didn't know who you were, and they think
+you have gone, for the two men on guard at the rear entrance so
+reported. Sometimes I stay out on the mountain for a couple of
+days at a time, when the weather's good, and don't go back to the
+cave. Those times I take food with me, and so if they see me
+making off with some supplies they'll think I'm going to camp
+out.&quot;</p>
+
+<p>&quot;It doesn't look as though we'd ever get into a cave near the
+top of the mountain, going this way,&quot; said Tom, as they marched
+along. &quot;We're going down, instead of up.&quot;</p>
+
+<p>&quot;That's the secret of this trail,&quot; explained Bill. &quot;We go down
+in a sort of valley, and then go up a pretty stiff place, and
+then we're on a direct trail to the entrance I told you about.
+It's a steep road to climb, but I guess we can manage it.&quot;</p>
+
+<p>And a hard climb the adventurers did find it. The road was
+almost as bad as the one along the edge of the chasm, but they
+managed to negotiate it, and finally found themselves on a fairly
+good trail.</p>
+
+<p>&quot;We'll soon be there,&quot; Bill assured them. &quot;After you get in the
+little cave, where I'm going to hide you, I'll have to leave you
+for a spell, until I get my ghost rigging fixed up again. But
+I'll see that you have plenty of food and drink.&quot;</p>
+
+<p>A little later their guide came to a sudden halt, and peered
+around anxiously.</p>
+
+<p>&quot;What's the matter?&quot; asked Tom.</p>
+
+<p>&quot;I was just looking to see if any of the men were about,&quot; he
+answered. &quot;But I guess not&mdash;it looks all right. The entrance is
+right here.&quot;</p>
+
+<p>They were on a side of the mountain, near the summit. Below
+stretched a magnificent scene. A great valley lay at their feet,
+and they could look off to many distant peaks. The main trail to
+Leadville, and the one to the settlement of Indian Ridge, was in
+sight.</p>
+
+<p>Suddenly Tom, who had been using a small but powerful
+telescope, uttered an exclamation, and focussed the instrument on
+a speck that seemed moving along on the trail below.</p>
+
+<p>&quot;A man&mdash;coming up the mountain,&quot; cried Tom. &quot;And&mdash;it can't be&mdash;yet
+it is&mdash;it's Farley Munson&mdash;the stowaway!&quot; he cried. &quot;He's coming here!&quot;</p>
+
+<p>&quot;Let me look!&quot; begged Mr. Jenks, taking the glass from Tom. An
+instant later the diamond man exclaimed: &quot;Yes, it's Munson!&quot;</p>
+
+<p>&quot;Then in here with you&mdash;quick!&quot; cried Renshaw. &quot;He can't see us
+yet, and we'll be out of sight in another minute.&quot;</p>
+
+<p>The former spirit pulled aside some thick bushes, and pointed
+to a hole which was disclosed.</p>
+
+<p>&quot;The entrance to the secret cave,&quot; he announced. &quot;Slip in all
+of you.&quot;</p>
+
+<p>Tom, after another glance at the man toiling his way up the
+mountain, entered the cavern. He was followed by the others. Bill
+was the last to enter, and he replaced the bushes over the
+entrance.</p>
+
+<p>&quot;At last!&quot; exclaimed Mr. Jenks, as he gazed up at the roof of
+the dimly-lighted vault in which they found themselves.</p>
+
+<p>&quot;Yes, we're in the diamond makers' secret cave,&quot; added Tom.
+&quot;Now to catch them at work!&quot;</p>
+
+<p>&quot;Come on,&quot; advised Bill, in a low tone, &quot;We're not safe yet,&quot;
+and he produced a lantern from some hidden recess, lighted the
+wick, and led the way. As the others followed they were aware of
+a subdued noise in the great cavern.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XX_MAKING_THE_DIAMONDS" id="CHAPTER_XX_MAKING_THE_DIAMONDS" />CHAPTER XX&mdash;MAKING THE DIAMONDS</h2>
+
+
+<p>&quot;What's that noise?&quot; asked Tom, as their guide flashed the
+lantern to show them the way.</p>
+
+<p>&quot;That's the men getting ready to make diamonds, I guess,&quot; was
+the answer. &quot;You see it takes quite a while to get the stuff
+ready. I don't know what they use&mdash;they never tell me any of
+their secrets.&quot;</p>
+
+<p>&quot;Oh, I know the ingredients well enough,&quot; said Mr. Jenks, &quot;but
+I don't know the secret of how they apply the terrific heat and
+pressure necessary to fuse the materials into diamonds.&quot;</p>
+
+<p>&quot;Well, you'll soon know,&quot; declared Bill Renshaw. &quot;Of course it
+isn't always successful. I've known 'em to try half a dozen times
+before they got any diamonds big enough to satisfy 'em. They gave
+me some of the small ones when I asked for my wages.</p>
+
+<p>&quot;How did you come to get in with these men?&quot; asked Tom, curious
+to understand how a person seemingly as honest as Renshaw
+appeared to be had cast his lot in with the men who had broken
+faith with Mr. Jenks.</p>
+
+<p>&quot;Oh, I've lived around these parts all my life,&quot; was the
+answer. &quot;I knew of this cave before these diamond fellers came to
+it. In fact, I showed it to 'em. It was several years ago that a
+party of men who were prospecting around here came to me and
+asked if I knew of a small cave near the top of a high mountain,
+where lightning storms were frequent. I told them about Phantom
+Mountain, as it was called then, and also of this cave. If
+there's any place where they have worse lightning storms than
+here, I'd like to know it. They scare me, sometimes, like the
+night when that landslide happened, and I'm sort of used to 'em.</p>
+
+<p>&quot;Well, I took these men to the cave, and they hired me as a
+sort of lookout. Then they began their work, and at first I
+didn't know what they were up to, but finally I caught on. Then
+Mr. Jenks came, and disappeared mysteriously, though then I
+didn't know that they had played a trick on him. I was outside
+most of the time, pretending I was the ghost. So that's how I
+came to get in with 'em, and I wish I was out.&quot;</p>
+
+<p>&quot;You soon will be, I think,&quot; declared Mr. Jenks. &quot;But won't our
+talking be heard by the men?&quot;</p>
+
+<p>&quot;No danger. There is a thick wall between this part of the
+cave, and the part where they live and work. I'll soon have you
+well hid, and then you wait until I come back.&quot;</p>
+
+<p>&quot;What about Munson?&quot; asked Tom. &quot;He is evidently on his way
+here to tell his confederates about us.&quot;</p>
+
+<p>&quot;He won't know what has happened to us,&quot; said Mr. Jenks, &quot;and
+he won't see anything of us. I guess we're safe enough.&quot;</p>
+
+<p>Through the dark passage they followed Bill Renshaw until he
+came to a halt in a place that suddenly widened and broadened
+into a good-sized cave.</p>
+
+<p>&quot;Here's your stopping place,&quot; said the former ghost. &quot;Now if
+you follow that passage, off to the left,&quot; and he pointed to it,
+&quot;you'll come to the larger part of the cave where the diamond
+makers are. But go cautiously, and don't make any noise. I won't
+be responsible for what happens.&quot;</p>
+
+<p>&quot;We'll take all the risk,&quot; interrupted Tom.</p>
+
+<p>&quot;All right. Now there's a couple of lanterns around here. I'll
+light them, and leave you for a while until I can get some grub.
+I'll be back as soon as I can.&quot;</p>
+
+<p>He glided away, after lighting two lanterns, by the gleams of
+which the adventurers could see that they were in a vaulted
+cavern that had evidently been fitted up as a living apartment.
+The sides, roof and floor were of stone. It was clean, and the
+air was fresh. There were some chairs, a table, and several cots,
+with pieces of bagging for bedding, though it was warm in the
+place.</p>
+
+<p>&quot;I guess we can stay here until we discover the secret,&quot; spoke
+Tom.</p>
+
+<p>&quot;Bless my watch! We can if we have something to eat,&quot; came from
+Mr. Damon, with something like a sigh. &quot;I'm hungry!&quot;</p>
+
+<p>&quot;And I want to make some observations,&quot; said Mr. Parker. &quot;From
+what I have seen of this mountain, I would not be surprised if
+this cave was to be suddenly destroyed by a landslide or a
+lightning bolt. I will make some further investigations.&quot;</p>
+
+<p>&quot;Well, if it's going to cause you to make such gloomy
+prophecies as that, I'd just as soon you wouldn't look any
+further,&quot; spoke Tom, in a low voice. But Mr. Parker, taking one
+of the lanterns, set about examining the rock of which the cave
+consisted.</p>
+
+<p>In a short time Bill Renshaw returned with enough food to last
+for two days. He said he was going out on the mountain once more
+to act the part of a lookout, and would visit the adventurers
+again the next day.</p>
+
+<p>&quot;In the meanwhile you can do just as you please,&quot; he said.
+&quot;Nobody is likely to disturb you here, and you can sneak up and
+take a look at the men in the other cave whenever you're ready.
+Only be careful&mdash;that's all I've got to say. They're desperate
+men.&quot;</p>
+
+<p>It was not very pleasant, eating in the gloomy cavern, but they
+made the best of it. They cooked on a small oil-stove they found
+in the place, and after some hot coffee they felt much better.</p>
+
+<p>&quot;Well,&quot; remarked Tom, after a while, &quot;shall we take a chance,
+and go look at the men at work?&quot;</p>
+
+<p>&quot;I think so,&quot; answered Mr. Jenks. &quot;The sooner we discover this
+mystery, the better. Then we can go back home.&quot;</p>
+
+<p>&quot;And recover my airship,&quot; added Tom, who was a bit uneasy
+regarding the safety of the Red Cloud.</p>
+
+<p>&quot;Then, bless my finger-rings! let's go and see if we can find
+the big cave your friend the ghost told us of,&quot; suggested Mr.
+Damon.</p>
+
+<p>Cautiously they made their way along the passage Bill had
+pointed out. As they went forward the subdued noise became
+louder, and finally they could feel the vibration of machinery.</p>
+
+<p>&quot;This is the place,&quot; whispered Mr. Jenks. &quot;That sound we hear
+is one of the mixing machines, for grinding the materials&mdash;carbon
+and the other substances&mdash;which go to make up the diamonds. I
+remember hearing that when I was in the cave before.&quot;</p>
+
+<p>&quot;Then we must be near the place,&quot; observed Tom.</p>
+
+<p>&quot;Yes, but I didn't have much chance to look around when I was
+here before. They wouldn't let me. I never even knew of the small
+cave Bill took us to.&quot;</p>
+
+<p>&quot;Well, if we're close to it, we'd better go cautiously, and not
+talk any more than we're obliged to,&quot; suggested Mr. Parker, and
+they agreed that this was good advice.</p>
+
+<p>They walked on softly. Suddenly Tom, who was in the lead, saw a
+gleam of light.</p>
+
+<p>&quot;We're here,&quot; he whispered. &quot;I'll put out our lantern, now,&quot;
+which he did. Then, stealing forward he and the others beheld a
+curious sight. The tunnel they were in ended at a small hole
+which opened into a large cavern, and, fortunately, this opening
+was concealed from the view of those in the main place.</p>
+
+<p>&quot;The diamond makers!&quot; whispered Tom, hoarsely, pointing to
+several men grouped about a number of strange machines.</p>
+
+<p>&quot;Yes&mdash;the very place where I was,&quot; answered Mr. Jenks, &quot;and
+there is the apparatus&mdash;the steel box&mdash;from which the diamonds
+are taken&mdash;now to see how they make them.&quot;</p>
+
+<p>Fascinated, the adventurers looked into the cave. The men there
+were unaware of the presence of our friends, and were busily
+engaged. Some attended to the grinding machine, the roar and
+clatter of which made it possible for Tom and the others to talk
+and move about without being overheard. Into this machine certain
+ingredients were put, and they were then pulverized, and taken
+out in powdery form.</p>
+
+<p>The power to run the mixing machine was a gasoline motor, which
+chug-chugged away in one corner of the cave.</p>
+
+<p>As the powder was taken out, other men fashioned it into small
+balls, which were put on pan, and into a sort of oven, that was
+heated by a gasoline stove.</p>
+
+<p>&quot;Is that how they make the diamonds?&quot; asked Mr. Damon.</p>
+
+<p>&quot;That is evidently the first step,&quot; said Mr. Jenks. &quot;Those
+balls of powdered chemicals are partly baked, and then they are
+put into the steel box. In some way terrific heat and pressure
+are applied, and the diamonds are made. But how the heat and
+pressure are obtained is what we have yet to learn.&quot;</p>
+
+<p>He paused to watch the men at work. They were all busy, some
+attending to the machines, and others coming and going in and out
+of the cave. In one part a man was apparently getting ready a
+meal.</p>
+
+<p>Suddenly there rushed into the cave a man who seemed much
+excited.</p>
+
+<p>&quot;Are you nearly ready with that stuff?&quot; he cried. &quot;There's a
+good storm gathering on the mountain!&quot;</p>
+
+<p>&quot;Yes, we'll be ready in half an hour,&quot; answered one of the men
+at the mixing machine.</p>
+
+<p>&quot;Good. It will be flashing lightning bolts then, and we can see
+what luck we have. The last batch was a failure.&quot; The man hurried
+out again. Mr. Parker touched Tom and Mr. Jenks on their
+shoulders.</p>
+
+<p>&quot;What is it?&quot; asked Tom.</p>
+
+<p>&quot;I know the secret of making the diamonds,&quot; said the scientist.</p>
+
+<p>&quot;What?&quot; cried Mr. Jenks.</p>
+
+<p>&quot;It is by the awful power of the lightning bolts!&quot; whispered
+Mr. Parker. &quot;Everything is explained now&mdash;the reason why they
+make diamonds in this lonely place, near the top of the mountain.
+They need a place where the lightning is powerful. I can
+understand it now&mdash;I suspected it before. They make diamonds by
+lightning!&quot;</p>
+
+<p>&quot;Are you sure?&quot; cried Mr. Jenks.</p>
+
+<p>&quot;Positive.&quot;</p>
+
+<p>&quot;I agree with you,&quot; said Tom Swift. &quot;I was just getting on that
+track myself, when I saw the electric wires running to the steel
+box. That explains the upright rod on the top of the mountain.
+The man says a storm is coming&mdash;very well; we'll stay here and
+watch them make diamonds!&quot;</p>
+
+<p>As he spoke there came the mutter of thunder, and the mountain
+vibrated slightly. The men in the cave redoubled their activity.
+Tom and his friends felt that the secret process they had so long
+sought was about to be demonstrated before their eyes.</p>
+
+
+
+<p>CHAPTER XXI&mdash;FLASHING GEMS</p>
+
+
+<p>Eagerly the adventurers looked through the opening at the end
+of the passage into the larger cave. The men opened the small
+oven in which the balls of white chemicals and carbon mixed, had
+been baked, and a pile of things, that looked like irregularly-shaped
+marbles, were placed in the steel box.</p>
+
+<p>This box, which was about the size of a trunk, was of massive
+metal. It was placed in a recess in the solid rock, and all about
+were layers of asbestos and other substances that were nonconductors
+of heat.</p>
+
+<p>&quot;That box becomes red hot,&quot; exclaimed Mr. Jenks, in a whisper.
+&quot;When things are in readiness, that lever is pulled and the
+diamonds are made. I pulled it once, but I did not then know the
+process involved. I supposed that the lightning had nothing to do
+with making the diamonds.&quot;</p>
+
+<p>&quot;It has&mdash;a most important part,&quot; said Mr. Parker. The hidden
+adventurers could talk in perfect safety now, for the men in the
+large cave were too excited to pay much attention to them. The
+muttering of the thunder grew louder, and at times a particularly
+loud crash told that a bolt had struck somewhere in the vicinity
+of the cave.</p>
+
+<p>&quot;But, bless my watch-charm!&quot; exclaimed Mr. Damon, &quot;I didn't
+know lightning made diamonds.&quot;</p>
+
+<p>&quot;It does not&mdash;always,&quot; went on the scientist. &quot;But great heat
+and pressure are necessary to create the gems. In nature this was
+probably obtained by prehistoric volcanic fires, and by the
+terrific pressure of immense rocks. It is possible to make
+diamonds in the laboratory of the chemist, but they are so minute
+as to be practically valueless.</p>
+
+<p>&quot;However, these men seem to have hit upon a new plan. They
+utilize the terrific heat of lightning, and the pressure which is
+instantaneously obtained when the bolt strikes. I am anxious to
+see how it is done. Look, I think they are getting ready to make
+the gems.&quot;</p>
+
+<p>Indeed there seemed to be an air of expectancy among the
+diamond makers. The mixing machine had now been stopped, and, as
+it was more quiet in the cave, our friends, in their hiding-place,
+had to speak in mere whispers. All the men were now gathered
+about the great steel box.</p>
+
+<p>This receptacle had been closed by a solid metal door, which
+was screwed and clamped tight. Then one of the men examined a
+number of heavily insulated electric wires that extended from the
+box off into the darkness where Tom and his companions could not
+discern them.</p>
+
+<p>&quot;That's Folwell&mdash;the man I befriended, and who got me into this
+game,&quot; whispered Mr. Jenks. &quot;He was also one of the first to turn
+against me. I think he's one of the leaders.&quot;</p>
+
+<p>Folwell came back, after having gone into a dark part of the
+cave. He went over to an electrical switch on one of the stone
+walls.</p>
+
+<p>&quot;It's almost time,&quot; Tom heard him say to his confederates. &quot;The
+storm is coming up rapidly.&quot;</p>
+
+<p>&quot;Will it be severe enough?&quot; asked one of the helpers. &quot;We had
+all our work for nothing last time. The flashes weren't heavy
+enough.&quot;</p>
+
+<p>&quot;These will be,&quot; asserted Folwell. &quot;The indicator shows nearly
+a million volts now, and it's increasing.&quot;</p>
+
+<p>&quot;A million volts!&quot; exclaimed Tom. &quot;I hope it doesn't strike
+anywhere around here.&quot;</p>
+
+<p>&quot;Oh, it will probably be harmlessly conducted down on the heavy
+wires,&quot; said Mr. Parker. &quot;We are in no danger, at present, though
+ultimately I expect to see the whole mountain shattered by a
+lightning bolt.&quot;</p>
+
+<p>&quot;Cheerful prospect,&quot; murmured Tom.</p>
+
+<p>There was a terrific crash outside. The rocky floor of the cave
+trembled.</p>
+
+<p>&quot;Here she comes!&quot; cried Folwell. &quot;Get back, everybody! I'm
+going to throw over the switch now!&quot;</p>
+
+<p>The men retreated well away from the steel box. Folwell threw
+over the lever&mdash;the same one Mr. Jenks remembered pulling. Then
+the man ran to the electric switch on the wall, and snapped that
+into place, establishing a connection.</p>
+
+<p>There was a moment's pause, as Folwell ran to join the others
+in their place of safety. Then from without there came a most
+nerve-racking and terrifying crash. It seemed as if the very
+mountain would be rent into fragments.</p>
+
+<p>Watching with eager eyes, the adventurers saw sparks flash from
+the steel box. Instantly it became red hot, and then glowed white
+and incandescent. It was almost at the melting point.</p>
+
+<p>Then came comparative quiet, as the echoes of the thunder died
+away amid the mountain peaks.</p>
+
+<p>&quot;I guess that did the trick!&quot; cried Folwell. &quot;It was a terrific
+crash all right!&quot;</p>
+
+<p>He and the others ran forward. The steel box was now a cherry
+red, for it was cooling. Folwell threw back the lever, and
+another man disconnected the switch. There was a period of
+waiting until the box was cool enough to open. Then the heavy
+door was swung back.</p>
+
+<p>With a long iron rod Folwell drew something from the retort. It
+was the tray which had held the white balls. But they were white
+no longer, for they had been turned into diamonds. From their
+hiding-place Tom and the others could see the flashing gems, for,
+in spite of the fact that the diamonds were uncut, some of them
+sparkled most brilliantly, due to the peculiar manner in which
+they were made.</p>
+
+<p>&quot;We have the secret of the diamonds!&quot; whispered Mr. Jenks.
+&quot;There must be a quart of the gems there!&quot;</p>
+
+<p>The men gathered about Folwell, uttering exclamations of
+delight. The diamonds were too hot to handle yet.</p>
+
+<p>&quot;That's going some!&quot; exclaimed the chief of the diamond makers.
+&quot;We have a small fortune here.&quot;</p>
+
+<p>The was a sudden commotion at one end of the cave. A man rushed
+in. At the sight of him Tom stared and uttered an exclamation.</p>
+
+<p>&quot;Munson&mdash;the stowaway!&quot; he whispered.</p>
+
+<p>&quot;Hello!&quot; cried Folwell, as he saw his confederate. &quot;I thought
+you were East, keeping Jenks away from here.&quot;</p>
+
+<p>&quot;He got the best of me!&quot; cried Munson, &quot;he and that Tom Swift!
+I stowed away on their airship, but they found me out by a
+wireless message, and marooned me in the woods. I've been trying
+to get here ever since! Didn't you get my messages of warning?&quot;</p>
+
+<p>&quot;No&mdash;what warnings ?&quot; cried Folwell.</p>
+
+<p>&quot;About Jenks, Tom Swift and the others. They're here&mdash;they must
+be on Phantom Mountain now. In fact, I shouldn't be surprised if
+they were in this cave. I traced them to their camp, but they're
+gone. They may be among us now&mdash;in some of the secret recesses!&quot;</p>
+
+<p>For an instant Folwell stared at the bearer of these tidings.
+Then he cried out:</p>
+
+<p>&quot;Scatter men, and find these fellows! We must get them before
+they discover our secret!&quot;</p>
+
+<p>&quot;It's too late&mdash;we know it!&quot; exulted Tom Swift. Then he
+whispered to the others to hurry to the part of the cave where
+Bill Renshaw had first hidden them.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XXII_PRISONERS" id="CHAPTER_XXII_PRISONERS" />CHAPTER XXII&mdash;PRISONERS</h2>
+
+
+<p>&quot;Do you think there is any danger of them finding us?&quot; asked
+Mr. Damon, as he hurried along beside Tom.</p>
+
+<p>&quot;I'm afraid so,&quot; was the answer. &quot;I've been worried ever since
+we saw Munson heading this way. But we couldn't do any differently.&quot;</p>
+
+<p>&quot;Perhaps Bill Renshaw may be able to conceal us,&quot; suggested Mr.
+Jenks. &quot;Very likely he knows that Munson is on hand. Perhaps we
+will be safe for a while. I want to make a few more observations
+as to how they manufacture the diamonds, and then, with what I
+already know, I'll have the secret.&quot;</p>
+
+<p>&quot;And I'd like to make some scientific tests of the sides and
+bottom rocks of the cave,&quot; spoke Mr. Parker. &quot;I think it will
+bear out my theory that the mountain will soon be destroyed.&quot;</p>
+
+<p>&quot;Well, you were right about Earthquake Island, and you may be
+right about this mountain,&quot; said Tom, &quot;but if it is going to be
+annihilated I hope we get far enough away from it.&quot;</p>
+
+<p>&quot;We can keep our presence here a secret for a few more days, I
+think that will be long enough,&quot; proceeded Mr. Jenks. &quot;Then we
+will leave.&quot;</p>
+
+<p>&quot;And, in the meanwhile, they'll be searching for us,&quot; objected
+Mr. Damon. &quot;I wish that ghost-chap would come back and tell us
+what to do. Bless my liver-pin, but we are going to be in
+considerable danger, I'm afraid! Those men may capture us, and
+decide to make diamond dust from us.&quot;</p>
+
+<p>&quot;Come on&mdash;hurry to the little cave,&quot; urged Tom. &quot;Then we'll get
+ready to defend ourselves.&quot;</p>
+
+<p>&quot;The main cave is a large one,&quot; said Mr. Jenks, &quot;and there are
+many hiding places in it. In fact, it is so large that it will
+take those fellows several days to complete a circuit of it. By
+that time Bill Renshaw may come back, and take us to some place
+in which they have already searched for us. Then we'll be
+comparatively safe.&quot;</p>
+
+<p>This thought was some consolation to them, as they made their
+way through the dark passage, dimly illuminated by the lantern
+they had rekindled, to the place where Bill had hidden them. They
+found things as they had left them, and proceeded to get a meal,
+though Tom said it would be best not to cook anything, or even to
+make coffee, for fear the odors would enable the searchers to
+trail them.</p>
+
+<p>So they ate cold food, glad to get that. Silently they sat
+about the dimly-lighted cavern, and discussed the situation. True
+they might even now retreat, going out of the entrance Bill had
+showed them, and so escape. But Mr. Jenks felt that his mission
+was not completed yet, and they all agreed to stay with him.</p>
+
+<p>&quot;For there are several points about making diamonds that are
+not quite clear to me,&quot; he said. &quot;I need to know how that steel
+box is constructed, how the electrical switches are arranged,
+what kind of lightning rods they use, and how they regulate the
+pressure. The other things, and how to mix the ingredients, I
+already know.&quot;</p>
+
+<p>&quot;Then we'll do our best to help you,&quot; promised Tom. &quot;But now I
+think we had better see what sort of a defense we can put up. We
+have our guns and revolvers, and with these chairs and tables we
+can build a sort of barricade behind which we can take refuge if
+those fellows do discover our hiding place.&quot;</p>
+
+<p>This was conceded to be a good idea, and soon a rude sort of
+fort was made, behind which the adventurers could take their
+stand and fight, if necessary, though they hoped this would not
+come to pass.</p>
+
+<p>They remained quietly in the cave the remainder of that day,
+and, when it was night, as they could tell by their timepieces&mdash;there
+was no daylight&mdash;they divided the hours into watches, taking turns
+standing guard.</p>
+
+<p>Morning, at least in point of time, came without any
+disturbance, and they made a cold breakfast. They hoped that Bill
+Renshaw would come, but he did not appear.</p>
+
+<p>After sitting in the dark cave until afternoon, Tom said:</p>
+
+<p>&quot;I think we might as well go and take another observation of
+the big cave. We can tell what the men are doing, then, for they
+don't seem to have been near us. Maybe they have given up the
+search for us, and we can see them at work, and Mr. Jenks can
+gain what further knowledge he needs.&quot;</p>
+
+<p>&quot;That will be a good plan,&quot; agreed the diamond man. &quot;It's
+maddening to sit here, doing nothing.&quot;</p>
+
+<p>&quot;And it will be comparatively safe to go from here to our
+former post of observation,&quot; added Tom, &quot;for there doesn't seem
+to be any opening along the tunnel, into the larger cave, except
+the place where we were.&quot;</p>
+
+<p>Accordingly they started off. Cautiously they looked through
+the opening into the apartment where they had seen the diamonds
+made.</p>
+
+<p>&quot;There's not a soul here!&quot; exclaimed Tom, in a whisper. The
+others looked. The place was deserted&mdash;the machinery silent. Mr.
+Jenks peered in for a moment, and then exclaimed:</p>
+
+<p>&quot;I'm going in! Now's my chance to find out all that I wish to
+know! It may never come again, and then we can soon leave Phantom
+Mountain!&quot;</p>
+
+<p>It was a daring plan, but it seemed to be the best one to
+follow. They were all tired of inactivity. Mr. Jenks managed to
+get through the opening, and dropped into the big cave. The
+others followed. Mr. Jenks hurried over to the steel box, and
+began an examination of it. Tom Swift was looking at the
+electrical switch. He saw how it was constructed. Mr. Damon and
+Mr. Parker were peering interestedly about.</p>
+
+<p>Suddenly the sound of voices was heard, and the echo of
+footsteps. Mr. Jenks started.</p>
+
+<p>&quot;They're coming back!&quot; he whispered hoarsely. &quot;Run!&quot;</p>
+
+<p>They all turned and sped toward their hiding place. But they
+were too late. An instant later Folwell, Munson and the other
+diamond makers confronted them. Our friends made a bold rush, but
+were caught before they could go ten feet.</p>
+
+<p>&quot;We have them!&quot; cried Munson. &quot;They walked right into our
+hands!&quot;</p>
+
+<p>It was true. Tom Swift and the others were the prisoners of the
+diamond makers.</p>
+
+
+
+<p>CHAPTER XXIII&mdash;BROKEN BONDS</p>
+
+
+<p>&quot;Well,&quot; remarked Tom Swift, in mournful tones, &quot;this looks as
+if we were up against it; doesn't it?&quot;</p>
+
+<p>&quot;Bless my umbrella, it certainly does,&quot; agreed Mr. Damon.</p>
+
+<p>&quot;And it's all my fault,&quot; said Mr. Jenks. &quot;I shouldn't have gone
+into the big cave. I might have known those men would come back
+any time.&quot;</p>
+
+<p>The above conversation took place as our friends lay securely
+bound in a small cave, or recess, opening from the larger cavern,
+where, about an hour before, they had been captured and made
+prisoners by the diamond makers. Despite their struggles they had
+been overpowered and bound, being carried to the cave, where they
+were laid in a row on some old bags.</p>
+
+<p>&quot;It certainly is a most unpleasant situation, to say the
+least,&quot; observed Mr. Parker.</p>
+
+<p>&quot;And all my fault,&quot; repeated Mr. Jenks.</p>
+
+<p>&quot;Oh, no it isn't,&quot; declared Tom Swift, quickly. &quot;We were just
+as ready to follow you into that cave as you were to go. No one
+could tell that the men would return so soon. It's nobody's
+fault. It's just our bad luck.&quot;</p>
+
+<p>From where he lay, tied hand and foot, the young inventor could
+look out into the cave where he and the others had been caught.
+The diamond makers were busily engaged, apparently in getting
+ready to manufacture another batch of the precious stones. They
+paid little attention to their captives, save to warn them, when
+they had first been taken into the little cave, that it was
+useless to try to escape.</p>
+
+<p>&quot;They needn't have told us that,&quot; observed Tom, as he and the
+others were talking over their situation in low voices. &quot;I don't
+believe any one could loosen these ropes.&quot;</p>
+
+<p>&quot;They certainly are pretty tight,&quot; agreed Mr. Damon. &quot;I've been
+tugging and straining at mine for the last half hour, and all
+I've succeeded in doing is to make the cords cut into my flesh.&quot;</p>
+
+<p>&quot;Better give it up,&quot; advised Mr. Jenks.</p>
+
+<p>&quot;We'll just have to wait.&quot;</p>
+
+<p>&quot;For what?&quot; the scientist wanted to know.</p>
+
+<p>&quot;To see what they'll do with us. They can't keep us here
+forever. They'll have to let us go some time.&quot; Following their
+capture, Folwell and Munson, the latter the stowaway of the
+airship, had been in earnest conversation regarding our friends,
+but what conclusion they had reached the adventurers could only
+guess.</p>
+
+<p>&quot;And we didn't have time to examine the diamond-making
+machinery close enough so that we could duplicate it if
+necessary,&quot; complained Tom, a little later.</p>
+
+<p>&quot;No,&quot; agreed Mr. Jenks. &quot;There are certain things about it that
+are not clear to me. Well, I don't believe I'll have another
+chance to inspect it. They'll take good care of that, though they
+seem to be getting ready to make more diamonds.&quot;</p>
+
+<p>&quot;Perhaps they're going to manufacture a big batch, and then
+leave this place,&quot; suggested Mr. Damon. &quot;They will probably go to
+some other secret cave, and leave us here.&quot;</p>
+
+<p>&quot;I hope they untie us before they leave, and give us something
+to eat,&quot; remarked the young inventor.</p>
+
+<p>For two hours longer the captives lay there, in most
+uncomfortable positions. Then Folwell and Munson, leaving the
+group of diamond makers who were grouped about the machinery,
+approached the captives.</p>
+
+<p>&quot;Well,&quot; remarked Munson, &quot;we got ahead of you after all; didn't
+we. You thought you had our secret, but it will be a long while
+before you ever make diamonds.&quot;</p>
+
+<p>&quot;What are you going to do with us?&quot; asked Tom.</p>
+
+<p>&quot;Never mind. You came where you had no right to, and you must
+take the consequences.&quot;</p>
+
+<p>&quot;We did have a right to come here!&quot; exclaimed Mr. Jenks. &quot;I am
+entitled to know how the diamonds are made. I paid for the
+information, and you tricked me. If ever it's possible I'll have
+the whole gang arrested for swindling.&quot;</p>
+
+<p>&quot;You'll never get the chance!&quot; declared Folwell. &quot;You were
+given some diamonds for the money you invested, and that makes us
+square.&quot;</p>
+
+<p>&quot;No, it doesn't!&quot; declared Mr. Jenks. &quot;I invested the money to
+learn how to make diamonds, and you know it! You tricked me, and
+I had a right to try to discover your secret! I nearly have it,
+too, and I'll get it completely before I'm done with you!&quot;</p>
+
+<p>&quot;No, you won't!&quot; boasted Folwell. &quot;But we didn't come here to
+tell you that. We came to give you something to eat. We're not
+savages and we'll treat you as well as we can in spite of the
+fact that you are trespassers. We're going to give you some grub,
+but I warn you that any attempt to escape will mean that some of
+you will get hurt.&quot;</p>
+
+<p>He signalled to some of his confederates. These men unbound the
+captives' arms, and stood over them while they ate some coarse
+food that was brought into the small cave. They were given coffee
+to drink, and then, when the simple meal was over, they were
+securely bound again, and left to themselves, while the diamond
+makers went back to their machinery.</p>
+
+<p>It was evident that they were going to attempt a big operation,
+for an unusually large quantity of the white stuff was prepared.
+The prisoners watched them idly. They could see some but not all
+of the operations. In this way several hours passed.</p>
+
+<p>Gloom possessed the hearts of Tom and his friends. Not only had
+their expedition been almost a failure so far, but the young
+inventor was worried lest the gang might discover and wreck his
+airship. This would prove a serious loss. Lying there in the
+semi-darkness the lad imagined all sorts of unpleasant happenings.</p>
+
+<p>At times he dozed off, as did the others. They had become
+somewhat used to the pain caused by the bonds, for their nerves
+were numb from the strain and pressure.</p>
+
+<p>Once, as he was lightly sleeping, Tom was awakened by hearing
+loud voices in the main cave. He looked out, rolling over
+slightly to get a better view. He saw the man who, once before
+had run in to give news of an approaching electrical storm.</p>
+
+<p>&quot;Are you fellows all ready?&quot; asked this same man again.</p>
+
+<p>&quot;Yes. Is there another storm coming?&quot;</p>
+
+<p>&quot;Yes, and it's going to be a corker!&quot; was the reply. &quot;It's one
+of the worst I've ever seen. It's sweeping right up the valley.
+It'll be here in an hour.&quot;</p>
+
+<p>&quot;That's good. We need a big flash to make all the material we
+have prepared into diamonds. It's the biggest batch we ever
+tried. I hope it succeeds, for we're going to leave&mdash;&quot; The rest
+was in so low a tone that Tom could not catch it.</p>
+
+<p>The storm messenger departed. Folwell and Munson busied
+themselves about the machinery. Tom dozed off again, dimly
+wondering what had become of Bill Renshaw, and whether the former
+ghost knew of their plight. The others were asleep, as the young
+inventor saw by the dim light of a lantern in the cave. Then, he
+too, shut his eyes.</p>
+
+<p>Tom was suddenly awakened by feeling some one's hands moving
+about his clothing. At first he thought it was one of the
+diamond-making gang, who had sneaked in to rob him. &quot;Here! What
+are you up to?&quot; exclaimed Tom.</p>
+
+<p>&quot;Quiet!&quot; cautioned a voice. &quot;Are you all here?&quot;</p>
+
+<p>&quot;All of us&mdash;yes. But who are you?&quot;</p>
+
+<p>&quot;Easy&mdash;keep quiet, Tom Swift! I'm Bill Renshaw! I've been
+searching all over for you, since I got back to your cave and
+found it empty. Now I'm going to free you. I got in here by a
+secret entrance. Wait, I'll cut your ropes.&quot; There was a slight
+sound, and an instant later Tom was freed from his bonds.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="CHAPTER_XXIV_IN_GREAT_PERIL" id="CHAPTER_XXIV_IN_GREAT_PERIL" />CHAPTER XXIV&mdash;IN GREAT PERIL</h2>
+
+
+<p>The young inventor could scarcely believe the good luck that
+had so unexpectedly come to him and his companions. No sooner was
+Tom able to move freely about than Bill Renshaw performed the
+same service for Mr. Jenks and the others, cautioning them to be
+quiet as he awakened them, and cut the ropes.</p>
+
+<p>&quot;Bless my circulation!&quot; exclaimed Mr. Damon, in a hoarse
+whisper. &quot;How did you ever get here. I'd given ourselves up for
+lost.&quot;</p>
+
+<p>&quot;Oh, I came in off the mountain, as there's a big storm due,&quot;
+explained the man. &quot;There was no need of me playing the haunt in
+daytime, anyhow. I went to the cave, found you and your things
+gone, and I surmised that you might have walked into some trap.&quot;</p>
+
+<p>&quot;We did,&quot; admitted Mr. Jenks, grimly.</p>
+
+<p>&quot;Well, I hunted around until I found you,&quot; went on Bill. &quot;This
+mountain is honeycombed with caves, all opening from the large
+one, I know them better than these fellows do, so I could explore
+freely, and keep out of their sight. They didn't know that there
+was a second entrance to this place, but I did, and I made for
+it, when I couldn't find you in some of the other caves where I
+looked. And, sure enough, here you were.&quot;</p>
+
+<p>&quot;Well, we can't thank you enough,&quot; said Mr. Parker. &quot;But you
+say there is a big storm coming?&quot;</p>
+
+<p>&quot;One of the biggest that's been around these parts in some
+time,&quot; replied Bill.</p>
+
+<p>&quot;Then perhaps the mountain will be destroyed,&quot; went on the
+scientist, as calmly as if he had remarked that it might rain.</p>
+
+<p>&quot;I hope nothing like that happens until we get away,&quot; spoke Mr.
+Damon, fervently.</p>
+
+<p>&quot;What had we better do?&quot; inquired Tom.</p>
+
+<p>&quot;Get away, unless you want to discover some more of their
+secrets,&quot; advised Bill. &quot;Those fellows are planning something,
+but I can't find out what it is. They are suspicious of me, I
+think. But they are up to something, and I believe, it would be
+best for you to leave while you have the chance. It may not be
+healthy to stay. That's why I did my best to untie you.&quot;</p>
+
+<p>&quot;We appreciate what you have done,&quot; declared Mr. Jenks, &quot;but I
+want my rights. I must learn a few more facts about how to make
+diamonds from lightning flashes, and then I will have the same
+secret they cheated me out of. I think if we wait a while we may
+be able to see the parts of the process that are not quite clear
+to us. What do you say, Tom Swift?&quot;</p>
+
+<p>&quot;Well, I would like to learn the secret,&quot; replied the lad, &quot;and
+if Bill thinks it's safe to stay here a while longer&mdash;&quot;</p>
+
+<p>&quot;Oh, I guess it will be safe enough,&quot; was the reply. &quot;Those
+fellows won't bother about you now that they are about to make
+some more diamonds. Besides, they think you're all tied up. Yes,
+you can stay here and watch, I reckon. I've got a couple of guns,
+and&mdash;&quot;</p>
+
+<p>&quot;Then we'll stay,&quot; decided Tom. &quot;We can put up a better fight
+now.&quot;</p>
+
+<p>Silently, in their prison, but which they could now leave
+whenever they pleased, the adventurers watched the diamond makers
+once more. The same process they had witnessed before was gone
+through with. The white balls were put inside the steel box and
+sealed up. Then they waited for the storm to reach its height.</p>
+
+<p>That this would not be long was evidenced by the mutterings of
+thunder which every moment grew louder. The outburst of
+electrical fury was likely to take place momentarily, and that it
+would be unusually severe was shown by the precautions taken by
+the diamond makers. They attached a number of extra wires, and
+brought out some insulated, hard rubber platforms, on which they
+themselves stood. Tom and Mr. Jenks were much interested in
+watching this detail of the work, and sought to learn how each
+part of the process was done.</p>
+
+<p>&quot;I almost think we can make diamonds, Tom, when we get back to
+civilization,&quot; whispered Mr. Jenks.</p>
+
+<p>&quot;I hope we can,&quot; answered Tom, &quot;and we can't get back any too
+soon to suit me. I want to be in my airship again.&quot;</p>
+
+<p>&quot;I don't blame you. But look, they are getting ready to adjust
+the switch.&quot;</p>
+
+<p>The adventurers ceased their whispered talk, and eagerly
+watched the diamond makers. Folwell and Munson were hurrying to
+and fro in the big cave, attending to the adjustments of the
+machinery.</p>
+
+<p>&quot;On your insulated plates&mdash;all of you,&quot; Folwell gave the order.
+&quot;This is going to be a terrific storm. The gage shows twice the
+power we have ever used, and it's creeping up every minute! We'll
+have more diamonds than ever had before!&quot;</p>
+
+<p>&quot;Yes, if the mountain isn't destroyed,&quot; added Mr. Parker, in a
+low voice. &quot;I predict that it will be split from top to bottom!&quot;</p>
+
+<p>&quot;Comforting,&quot; thought Tom, grimly.</p>
+
+<p>&quot;I guess we're all ready,&quot; said Folwell, in a low tone to
+Munson. &quot;We'd better get insulated ourselves. I'm going to throw
+the switch.&quot;</p>
+
+<p>He did so. A moment later the man who had before given warning
+of the storm came dashing in. He was very much excited.</p>
+
+<p>&quot;It's awful!&quot; he cried. &quot;The lightning is striking all over!
+Big rocks are being split like logs of wood!&quot;</p>
+
+<p>&quot;Well, it can't do any damage in here,&quot; said Munson. &quot;We are
+well protected. Get on one of the plates,&quot; and he motioned to one
+of the hard-rubber platforms that was not occupied. The roar and
+rumble of the storm outside had given place to short terrific
+crashes. In their small cave the adventurers could feel the solid
+ground shake.</p>
+
+<p>A bluish light began dancing about the electrical wires. There
+was a smell of sulphur in the air. Crash after crash resounded
+outside. A flash of flame lit up the whole interior of the cave.
+It came from the copper switch.</p>
+
+<p>&quot;Something's wrong with the insulation!&quot; cried Munson.</p>
+
+<p>&quot;Don't go near it!&quot; yelled Folwell. &quot;If you value your life,
+stand still!&quot;</p>
+
+<p>Hardly had he spoken than inside the cavern there sounded a
+report like that of a small cannon. A big ball of fire danced
+about the middle of the cave and then leaped on top of the steel
+box.</p>
+
+<p>&quot;This is a fearful storm,&quot; cried Munson.</p>
+
+<p>The adventurers in the cave did not know what to say or do.
+They were in deadly peril.</p>
+
+<p>Suddenly there came a crash louder than any that had preceded
+it. The whole side of the cave where the switches were was a mass
+of bluish flame. Then came a ripping, tearing sound, and a tangle
+of wires and copper connections were thrown to the floor. At the
+same time the steel box, containing the materials from which
+diamonds were made, turned blue, and flames shot from it.</p>
+
+<p>&quot;It's all up with us!&quot; cried Munson. &quot;Run for it, everybody!
+The wires are down, and this place will be an electric furnace in
+another minute!&quot;</p>
+
+<p>He leaped toward the exit from the cave.</p>
+
+<p>&quot;What about those fellows?&quot; asked Folwell, indicating the place
+where Tom and the others had been tied.</p>
+
+<p>&quot;They'll have to do the best they can! It's every man for
+himself, now!&quot; yelled Munson. There was a wild scramble from the
+cavern.</p>
+
+<p>&quot;Come on!&quot; cried Tom. &quot;We must escape! It's our only chance!&quot;</p>
+
+<p>He leaped into the big cave, followed by the others. Already
+long tongues of electrical fire were shooting out from the walls
+and roof as Tom Swift and his companions, evading them as best
+they could, sought safety in flight.</p>
+
+
+
+<p>CHAPTER XXV&mdash;THE MOUNTAIN SHATTERED&mdash;CONCLUSION</p>
+
+
+<p>&quot;Can't we get some of the diamonds?&quot; cried Mr. Damon, as he
+raced along behind Tom. &quot;Now's our chance. Those fellows have all
+gone!&quot; The odd man made a grab for something as he ran.</p>
+
+<p>&quot;It's as much as our lives are worth,&quot; declared the young
+inventor. &quot;We dare not stop! Come on!&quot;</p>
+
+<p>&quot;I'd like to investigate some of the machinery,&quot; spoke Mr.
+Jenks, &quot;but I wouldn't stop, even for that.&quot;</p>
+
+<p>&quot;The storm is too dangerous,&quot; called Bill Renshaw. &quot;I can show
+you a shorter way out than the one those fellows have taken.
+Follow me.&quot;</p>
+
+<p>&quot;No way can be too short,&quot; said Mr. Parker, solemnly. &quot;This
+mountain will go to pieces shortly, I think!&quot;</p>
+
+<p>Tom shuddered. He remembered how narrow had been their escape
+when Earthquake Island sank into the sea. And that some terrific
+upheaval was now imminent might be judged from the awful reports
+that sounded more plainly as the adventurers raced toward the
+opening of the cave. It was like the bombardment of some doomed
+city.</p>
+
+<p>Mr. Jenks and Tom cast one longing look behind at the
+complicated and expensive machinery that had been installed in
+the cave by the diamond makers. They had abandoned it, and in it
+lay the secret of making precious gems. But there was no time to
+stop now, and investigate.</p>
+
+<p>&quot;This way,&quot; urged Bill Renshaw. &quot;We'll soon be out.&quot;</p>
+
+<p>&quot;But won't it be dangerous to go outside?&quot; asked Mr. Damon.
+&quot;Shan't we be struck by lightning? There is some protection in
+here.&quot;</p>
+
+<p>&quot;None at all,&quot; said Mr. Parker, quickly. &quot;This mountain is a
+natural lightning rod. To stay here in this cave will be sure
+death when the storm gets directly over it. And that will be very
+soon. We must get on insulated ground. Is there any part of this
+mountain that does not contain iron ore?&quot; the scientist asked of
+the former spirit.</p>
+
+<p>&quot;Yes; the way out by which we are going lands on a dirt hill.&quot;</p>
+
+<p>&quot;That's good; then we may be saved.&quot;</p>
+
+<p>On they ran. They had no lanterns, but the blue light of the
+electricity, as it leaped from point to point inside the cave,
+where there were outcroppings of iron ore, made the place bright
+enough to see.</p>
+
+<p>&quot;Here we are!&quot; cried Bill Renshaw at length. &quot;Here's the way
+out!&quot;</p>
+
+<p>Making a sudden turn in the winding passage he showed the
+adventurers a small opening in the side of the crag. In an
+instant they had passed through, and found themselves in daylight
+once more. The sudden glare almost blinded them, for, though the
+sky was overcast by clouds, from which jagged tongues of
+lightning played, the outside was much lighter than the dark
+cave.</p>
+
+<p>&quot;I should say it was a storm!&quot; cried Tom Swift. &quot;See, it is
+striking every minute, and all around us!&quot;</p>
+
+<p>In fact, lightning bolts were falling on every side of the
+adventurers. Every time the balls of fire struck, they burst open
+great stones, or seared a livid scar on the face of some cliff.
+As for Tom and the others, they stood on a dry dirt hill, in
+which, fortunately, there was no iron ore. To this fact they
+undoubtedly owed their lives, though had there been rain, to
+moisten the ground and make the earth a good conductor of
+electricity, they probably would have been badly shocked. But the
+electrical outburst was not accompanied by rain.</p>
+
+<p>Tom looked up. He saw a compact mass of cloud moving toward the
+summit of the mountain on the slope of which they stood. From
+this cloud there played shafts of reddish-green fire.</p>
+
+<p>&quot;Look!&quot; called the young inventor to Mr. Parker. The instant
+the latter saw the cloud, he cried:</p>
+
+<p>&quot;We must get away from here by all means! That is the center of
+the storm. As soon as it gets over the mountain, where that
+lightning rod is, all the electrical fluid will be discharged in
+one bolt at the mountain, and it will be destroyed! We must run,
+but keep on the dirt places! Run for your lives!&quot;</p>
+
+<p>They needed no second warning. Turning, they fled down the
+steep side of the mountain, slipping and stumbling, but taking
+care not to step on any iron ore. Behind them flashed the
+lightning bolts.</p>
+
+<p>Suddenly there was a most awful crash. It seemed as if the end
+of the world had come, and the ear drums of Tom and his
+companion almost burst with the fearful report. The concussion
+knocked them down, and they lay stunned for a moment.</p>
+
+<p>Following the terrible report there was a low, rumbling sound.
+Hardly knowing whether he was dead or alive, Tom opened his eyes
+and looked about him. What he saw caused him to cry out in
+terror.</p>
+
+<p>The whole mountain seemed bathed in fire. Great blue, red and
+green flashes played around it. Then the towering cliff seemed to
+melt and crumble up, and the great peak, the top of it containing
+the diamond makers' cave, from which they had fled but a few
+minutes before, the entire summit was toppled over into the
+valley on the other side, and in the direction opposite to that
+where the adventurers stood.</p>
+
+<p>Then came a profound silence, and the lightning ceased. The
+storm was over, and only the rattle of stones and boulders, as
+they came to rest in the valley below, reached the ears of our
+friends.</p>
+
+<p>&quot;Phantom Mountain has been destroyed, just as I said it would
+be,&quot; spoke Mr. Parker, solemnly. Once more he had prophesied
+correctly.</p>
+
+<p>For a few minutes the adventurers hardly knew what to say. They
+arose awkwardly from the ground where the shock had tossed them.
+Then Tom remarked, as calmly as possible:</p>
+
+<p>&quot;Well, it's all over. I guess we may as well get back to our
+airship.&quot;</p>
+
+<p>&quot;What became of Munson and the others?&quot; asked Mr. Damon.</p>
+
+<p>Mr. Jenks pointed to the trail, far below. The figures of some
+men, running madly, could be seen.</p>
+
+<p>&quot;There they go,&quot; he said; &quot;I fancy we have seen the last of
+them.&quot; And they had, for some time at least.</p>
+
+<p>There was little use lingering any longer on Phantom Mountain&mdash;indeed
+little of it was left on which to remain. Looking back
+toward the place where the cave had been, Tom and the others
+started forward again. The diamond-making machinery had all been
+destroyed. So, also, had the finished diamonds stored in the
+cavern and the large supply which had probably been made by the
+last terrific crash. No one would ever have them now. Tom and Mr.
+Jenks felt a sense of disappointment, but they were glad to have
+escaped with their lives. They sought their former camp, but the
+tent and all their food was buried under tons of earth and rocks.</p>
+
+<p>Three days later, after rather severe hardships, they were near
+the place where they had left the Red Cloud. They had suffered
+cold and hunger, for they had no food supplies, and, had it not
+been that Bill Renshaw knew the haunts of some game, of which
+they managed to snare some, they would have fared badly, for they
+had left their guns in the cave.</p>
+
+<p>&quot;Well, there are the trees behind which I hope my airship is
+hidden,&quot; announced Tom, as they came to the spot. &quot;Good old Red
+Cloud! Maybe we won't do some eating when we get aboard, eh?&quot;</p>
+
+<p>&quot;Bless my appetite! but we certainly will!&quot; cried Mr. Damon.</p>
+
+<p>&quot;There's somebody walking around the place,&quot; spoke Mr. Jenks.</p>
+
+<p>&quot;I hope it's no one who has damaged the ship,&quot; came from Tom,
+apprehensively. He broke into a run, and soon confronted an aged
+miner, who seemed to have established a rude sort of camp near
+the airship.</p>
+
+<p>&quot;Is anything the matter?&quot; asked Tom, breathlessly. &quot;Is my
+airship all right?&quot;</p>
+
+<p>&quot;I guess she's all right, stranger,&quot; was the reply. &quot;I don't
+know much about these contraptions, but I haven't touched her. I
+knowed she was an airship, for I've seen pictures of 'em, and
+I've been waiting until the owner came along.&quot;</p>
+
+<p>&quot;Why?&quot; asked Tom, wonderingly.</p>
+
+<p>&quot;Because I've got a proposition to make to you,&quot; went on the
+miner, who said his name was Abe Abercrombie. &quot;I've been a miner
+for a good many years, and I'm just back from Alaska, prospecting
+around here. I haven't had any luck, but I know of a gold mine
+in Alaska that will make us all rich. Only it needs an airship to
+get to it, and I've been figuring how to hire one. Then I comes
+along, and I sees this big one, and I makes up my mind to stay
+here until the owners come back. That's what I've done. Now, if I
+prove that I'm telling the truth, will you go to Alaska&mdash;to the
+valley of gold with me?&quot;</p>
+
+<p>&quot;I don't know,&quot; answered Tom, to whom the proposition was
+rather sudden. &quot;We've just had some pretty startling adventures,
+and we're almost starved. Wait until we get something to eat, and
+we'll talk. Come aboard the Red Cloud,&quot; and the lad led the way
+to his craft which was in as good condition as when he left it to
+go to the diamond cave. Later he listened to the miner's story.</p>
+
+<p>Tom Swift did go to the valley of gold in Alaska, and what
+happened to him and his companions there will be told of in the
+next volume of this series, to be called &quot;Tom Swift in the Caves
+of Ice; or, the Wreck of the Airship.&quot;</p>
+
+<p>It did not take our friends long, after they had eaten a hearty
+meal, to generate some fresh gas, and start the Red Cloud oh her
+homeward way. Tom wanted to take Bill Renshaw with him, but the
+old man said he would rather remain among the mountains where he
+had been born. So, after paying him well for his services, they
+said good-by to him. Abercrombie, the miner, also remained
+behind, but promised to call and see Tom in a few months.</p>
+
+<p>&quot;Well, we didn't make any money out of this trip,&quot; observed Mr.
+Jenks, rather dubiously, as they were nearing Shopton, after an
+uneventful trip. &quot;I guess I owe you considerable, Tom Swift. I
+promised to get you a lot of diamonds, but all I have are those I
+had from my first visit to the cave.&quot;</p>
+
+<p>&quot;Oh, that's all right,&quot; spoke Tom, easily. &quot;The experience was
+worth all the trip cost.&quot;</p>
+
+<p>&quot;Speaking of diamonds, look here!&quot; exclaimed Mr. Damon,
+suddenly, and he pulled out a double handful.</p>
+
+<p>&quot;Where did you get them?&quot; cried the others in astonishment.</p>
+
+<p>&quot;I grabbed them up, as we ran from the cave,&quot; said the
+eccentric man; &quot;but, bless my gaiters! I forgot all about them
+until you spoke. We'll share them.&quot;</p>
+
+<p>These diamonds, some of which were large, proved very valuable,
+though the total sum was far below what Mr. Jenks hoped to make
+when he started on the remarkable trip. Tom gave Mary Nestor a
+very fine stone, and it was set in a ring, instead of a pin, this
+time.</p>
+
+<p>On their arrival in Shopton, where Mr. Swift, the housekeeper,
+Mr. Jackson and Eradicate Sampson were much alarmed for Tom's
+safety, an attempt was made to manufacture diamonds, using a
+powerful electric current instead of lightning. But it was not a
+success, and so Mr. Jenks concluded to give up his search for the
+secret which was lost on Phantom Mountain.</p>
+
+<p>And now we will take leave of Tom Swift, to meet him again soon
+in other adventures he is destined to have in the caves of ice
+and the valley of gold.</p>
