+Project Gutenberg Etexts are often created from several printed
+editions, all of which are confirmed as Public Domain in the US
+unless a copyright notice is included. Thus, we usually do not
+keep etexts in compliance with any particular paper edition.
+
+We are now trying to release all our etexts one year in advance
+of the official release dates, leaving time for better editing.
+Please be encouraged to tell us about any error or corrections,
+even years after the official publication date.
+
+Please note neither this listing nor its contents are final til
+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.
+
+Most people start at our sites at:
+http://gutenberg.net or
+http://promo.net/pg
+
+These Web sites include award-winning information about Project
+Gutenberg, including how to donate, how to help produce our new
+etexts, and how to subscribe to our email newsletter (free!).
+
+
+Those of you who want to download any Etext before announcement
+can get to them as follows, and just download by date. This is
+also a good way to get them instantly upon announcement, as the
+indexes our cataloguers produce obviously take a while after an
+announcement goes out in the Project Gutenberg Newsletter.

+Information about Project Gutenberg (one page)
+
+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any etext selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2001 as we release over 50 new Etext
+files per month, or 500 more Etexts in 2000 for a total of 4000+
+If they reach just 1-2% of the world's population then the total
+should reach over 300 billion Etexts given away by year's end.
+
+The Goal of Project Gutenberg is to Give Away One Trillion Etext
+Files by December 31, 2001. [10,000 x 100,000,000 = 1 Trillion]
+This is ten thousand titles each to one hundred million readers,
+which is only about 4% of the present number of computer users.
+
+At our revised rates of production, we will reach only one-third
+of that goal by the end of 2001, or about 4,000 Etexts. We need
+funding, as well as continued efforts by volunteers, to maintain
+or increase our production and reach our goals.
+
+The Project Gutenberg Literary Archive Foundation has been created
+to secure a future for Project Gutenberg into the next millennium.

+CHAPTER I
+
+A MAN ON THE ROOF
+
+
+"Tom, I don't believe it can be done!"
+
+"But, Dad, I'm sure it can!"
+
+Tom Swift looked over at his father, who was seated in an easy
+chair in the library. The elderly gentleman--his hair was quite
+white now--slowly shook his head, as he murmured again:
+
+"It can't be done, Tom! It can't be done! I admit that you've made
+a lot of wonderful things--things I never dreamed of--but this is
+too much. To transmit pictures over a telephone wire, so that
+persons cannot only see to whom they are talking, as well as hear
+them--well, to be frank with you, Tom, I should be sorry to see
+you waste your time trying to invent such a thing."
+
+"I don't agree with you. Not only do I think it can be done, but
+I'm going to do it. In fact, I've already started on it. As for
+wasting my time, well, I haven't anything in particular to do, now
+that my giant cannon has been perfected, so I might as well be
+working on my new photo telephone instead of sitting around idle."
+
+"Yes, Tom, I agree with you there," said Mr. Swift. "Sitting
+around idle isn't good for anyone--man or boy, young or old. So
+don't think I'm finding fault because you're busy."
+
+"It's only that I don't want to see you throw away your efforts,
+only to be disappointed in the end. It can't be done, Tom, it
+can't be done," and the aged inventor shook his head in pitying
+doubt.
+
+Tom only smiled confidently, and went on:
+
+"Well, Dad, all you'll have to do will be to wait and see. It
+isn't going to be easy--I grant that. In fact, I've run up against
+more snags, the little way I've gone so far, than I like to admit.
+But I'm going to stick at it, and before this year is out I'll
+guarantee, Father, that you can be at one end of the telephone
+wire, talking to me, at the other, and I'll see you and you'll see
+me--if not as plainly as we see each other now, at least plainly
+enough to make sure of each other."
+
+Mr. Swift chuckled silently, gradually breaking into a louder
+laugh. Instead of being angry, Tom only regarded his father with
+an indulgent smile, and continued:
+
+"All right, Dad. Go ahead, laugh!"
+
+"Well, Tom, I'm not exactly laughing at YOU--it's more at the
+idea than anything else. The idea of talking over a wire and, at
+the same time, having light waves, as well as electrical waves
+passing on the same conductor!"
+
+"All right, Dad, go ahead and laugh. I don't mind," said Tom,
+good-naturedly. "Folks laughed at Bell, when he said he could send
+a human voice over a copper spring; but Bell went ahead and to-day
+we can talk over a thousand miles by wire. That was the telephone."
+
+"Folks laughed at Morse when he said he could send a message over
+the wire. He let 'em laugh, but we have the telegraph. Folks
+laughed at Edison, when he said he could take the human voice--or
+any other sound--and fix it on a wax cylinder or a hard-rubber
+plate--but he did it, and we have the phonograph. And folks
+laughed at Santos Dumont, at the Wrights, and at all the other
+fellows, who said they could take a heavier-than-air machine, and
+skim above the clouds like a bird; but we do it--I've done it--
+you've done it."
+
+"Hold on, Tom!" protested Mr. Swift. "I give up! Don't rub it in
+on your old dad. I admit that folks did laugh at those inventors,
+with their seemingly impossible schemes, but they made good. And
+you've made good lots of times where I thought you wouldn't. But
+just stop to consider for a moment. This thing of sending a
+picture over a telephone wire is totally out of the question, and
+entirely opposed to all the principles of science."
+
+"What do I care for principles of science?" cried Tom, and he
+strode about the room so rapidly that Eradicate, the old colored
+servant, who came in with the mail, skipped out of the library
+with the remark:
+
+"Deed, an' Massa Tom must be pow'fully preragitated dis mawnin'!"
+
+"Some of the scientists said it was totally opposed to all natural
+laws when I planned my electric rifle," went on Tom. "But I made
+it, and it shot. They said my air glider would never stay up, but
+she did."
+
+"But, Tom, this is different. You are talking of sending light
+waves--one of the most delicate forms of motion in the world--over
+a material wire. It can't be done!"
+
+"Look here, Dad!" exclaimed Tom, coming to a halt in front of his
+parent. "What is light, anyhow? Merely another form of motion;
+isn't it?"
+
+"Well, yes, Tom, I suppose it is."
+
+"Of course it is," said Tom. "With vibrations of a certain length
+and rapidity we get sound--the faster the vibration per second the
+higher the sound note. Now, then, we have sound waves, or
+vibrations, traveling at the rate of a mile in a little less than
+five seconds; that is, with the air at a temperature of sixty
+degrees. With each increase of a degree of temperature we get an
+increase of about a foot per second in the rapidity with which
+sound travels."
+
+"Now, then, light shoots along at the rate of 186,000,000 miles a
+second. That is more than many times around the earth in a second
+of time. So we have sound, one kind of wave motion, or energy; we
+have light, a higher degree of vibration or wave motion, and then
+we come to electricity--and nobody has ever yet exactly measured
+the intensity or speed of the electric vibrations."
+
+"But what I'm getting at is this--that electricity must travel
+pretty nearly as fast as light--if not faster. So I believe that
+electricity and light have about the same kind of vibrations, or
+wave motion."
+
+"Now, then, if they do have--and I admit it's up to me to prove
+it," went on Tom, earnestly--"why can't I send light-waves over a
+wire, as well as electrical waves?"
+
+Mr. Swift was silent for a moment. Then he said, slowly:
+
+"Well, Tom, I never heard it argued just that way before. Maybe
+there's something in your photo telephone after all. But it never
+has been done. You can't deny that!"
+
+He looked at his son triumphantly. It was not because he wanted to
+get the better of him in argument, that Mr. Swift held to his own
+views; but he wanted to bring out the best that was in his
+offspring. Tom accepted the challenge instantly.
+
+"Yes, Dad, it has been done, in a way!" he said, earnestly. "No
+one has sent a picture over a telephone wire, as far as I know,
+but during the recent hydroplane tests at Monte Carlo, photographs
+taken of some of the events in the morning, and afternoon, were
+developed in the evening, and transmitted over five hundred miles
+of wire to Paris, and those same photographs were published in the
+Paris newspapers the next morning."
+
+"Is that right, Tom?"
+
+"It certainly is. The photographs weren't so very clear, but you
+could make out what they were. Of course that is a different
+system than the one I'm thinking of. In that case they took a
+photograph, and made a copper plate of it, as they would for a
+half-tone illustration. This gave them a picture with ridges and
+depressions in copper, little hills and valleys, so to speak,
+according to whether there were light or dark tints in the
+picture. The dark places meant that the copper lines stood up
+higher there than where there were light colors."
+
+"Now, by putting this copper plate on a wooden drum, and revolving
+this drum, with an electrical needle pressing lightly on the
+ridges of copper, they got a varying degree of electrical current.
+Where the needle touched a high place in the copper plate the
+contact was good, and there was a strong current. When the needle
+got to a light place in the copper--a depression, so to speak--the
+contact was not so good, and there was only a weak current."
+
+"At the receiving end of the apparatus there was a sensitized film
+placed on a similar wooden drum. This was to receive the image
+that came over the five hundred miles of wire. Now then, as the
+electrical needle, moving across the copper plate, made electrical
+contacts of different degrees of strength, it worked a delicate
+galvanometer on the receiving end. The galvanometer caused a beam
+of light to vary--to grow brighter or dimmer, according as the
+electrical current was stronger or weaker. And this light, falling
+on the sensitive plate, made a picture, just like the one on the
+copper plate in Monte Carlo."
+
+"In other words, where the copper plate was black, showing that
+considerable printing ink was needed, the negative on the other
+end was made light. Then when that negative was printed it would
+come out black, because more light comes through the light places
+on a photograph negative than through the dark places. And so,
+with the galvanometer making light flashes on the sensitive plate,
+the galvanometer being governed by the electrical contacts five
+hundred miles away, they transmitted a photograph by wire."
+
+"But not a telephone wire, Tom."
+
+"That doesn't make any difference, Dad. It was a wire just the
+same. But I'm not going into that just now, though later I may
+want to send photographs by wire. What I'm aiming at is to make an
+apparatus so that when you go into a telephone booth to talk to a
+friend, you can see him and he can see you, on a specially
+prepared plate that will be attached to the telephone."
+
+"You mean see him as in a looking-glass, Tom?"
+
+"Somewhat, yes. Though I shall probably use a metal plate instead
+of glass. It will be just as if you were talking over a telephone
+in an open field, where you could see the other party and he could
+see you."
+
+"But how are you going to do it, Tom?"
+
+"Well, I haven't quite decided. I shall probably have to use the
+metal called selenium, which is very sensitive to light, and which
+makes a good or a poor electrical conductor according as more or
+less light falls on it. After all, a photograph is only lights and
+shadows, fixed on sensitive paper or films."
+
+"Well, Tom, maybe you can do it, and maybe you can't. I admit
+you've used some good arguments," said Mr. Swift. "But then, it
+all comes down to this: What good will it be if you can succeed in
+sending a picture over a telephone wire?"
+
+"What good, Dad? Why, lots of good. Just think how important it
+will be in business, if you can make sure that you are talking to
+the party you think you are. As it is now, unless you know the
+person's voice, you can't tell that the man on the other end of
+the wire is the person he says he is. And even a voice can be
+imitated."
+
+"But if you know the person yourself, he can't be imitated. If you
+see him, as well as hear his voice, you are sure of what you are
+doing. Why, think of the big business deals that could be made
+over the telephone if the two parties could not only hear but see
+each other. It would be a dead sure thing then. And Mr. Brown
+wouldn't have to take Mr. Smith's word that it was he who was
+talking. He could even get witnesses to look at the wire-image if
+he wanted to, and so clinch the thing. It will prevent a lot of
+frauds."
+
+"Well, Tom, maybe you're right. Go ahead. I'll say no more against
+your plans. I wish you all success, and if I can help you, call on
+me."
+
+"Thanks, Dad. I knew you'd feel that way when you understood. Now
+I'm going--"
+
+But what Tom Swift was going to do he did not say just then, for
+above the heads of father and son sounded a rattling, crashing
+noise, and the whole house seemed to shake Then the voice of
+Eradicate was heard yelling:
+
+"Good land! Good land ob massy! Come out yeah, Massa Tom! Come
+right out yeah! Dere's a man on de roof an' he am all tangled up
+suthin' scandalous! Come right out yeah befo' he falls and
+translocates his neck! Come on!"
+
+
+
+
+
+CHAPTER II
+
+BAD NEWS
+
+
+With startled glances at each other, Tom and his father rushed
+from the library to the side of the house, whence came the cries
+of Eradicate.
+
+"What is it, Rad! what is it?" questioned Tom.
+
+"Is someone hurt?" Mr. Swift wanted to know.
+
+"He mighty soon will be!" exclaimed the colored man. "Look where
+he am holdin' on! Lucky fo' him he grabbed dat chimbley!"
+
+Tom and his father looked to where Eradicate pointed, and saw a
+strange sight. A small biplane-airship had become entangled in
+some of the aerials of Tom's wireless apparatus, and the craft had
+turned turtle, being held from falling by some of the wire braces.
+
+The birdman had fallen out, but had managed to cling to the
+chimney, so that he had not reached the ground, and there he
+clung, while the motor of his airship was banging away, and
+revolving the propeller blades dangerously close to his head.
+
+"Are you hurt?" cried Tom, to the unknown birdman.
+
+"No, but I'm likely to be unless I get out of here!" was the
+gasped-out answer.
+
+"Hold fast!" cried Tom. "We'll have you down in a jiffy. Here,
+Rad, you get the long ladder. Where's Koku? That giant is never
+around when he's wanted. Find Koku, Rad, and send him here."
+
+"Yas, sah, Massa Tom; directly, sah!" and the colored man hastened
+off as fast as his aged legs would take him.
+
+And while preparations are thus under way to rescue the birdman
+from the roof, I will take just a few minutes to tell you a little
+something more about Tom Swift and his numerous inventions, as set
+forth in the previous books of this series.
+
+"Tom Swift and His Motor Cycle" was the first book, and in that I
+related how Tom made the acquaintance of a Mr. Wakefield Damon, of
+the neighboring town of Waterford, and how Tom bought that
+gentleman's motor cycle, after it had tried to climb a tree with
+its rider in the saddle. Mr. Wakefield Damon was an odd man, whose
+favorite expression was "Bless my shoelaces!" or something equally
+absurd. Waterford was not far from Shopton, where Tom and his
+father made their home.
+
+Mr. Swift was also an inventor of note, and Tom soon followed in
+his father's footsteps. They lived in a large house, with many
+shops about it, for their work at times required much machinery.
+
+Mrs. Baggert was the housekeeper who looked after Tom and his
+father, and got their meals, when they consented to take enough
+time from their inventive work to eat. Another member of the
+household was Eradicate Sampson, a genial old colored man, who
+said he was named Eradicate because he used to eradicate the dirt
+about the place.
+
+Koku, just referred to by Tom, was an immense man, a veritable
+giant, whom Tom had brought back with him from one of his trips,
+after escaping from captivity. The young inventor really brought
+two giants, brothers they were, but one had gone to a museum, and
+the other took service with our hero, making himself very useful
+when it came to lifting heavy machinery.
+
+Tom had a close friend in Ned Newton, who was employed in the
+Shopton bank. Another friend was Miss Mary Nestor, a young lady
+whose life Tom had once saved. He had many other friends, and some
+enemies, whom you will meet from time to time in this story.
+
+After Tom had had many adventures on his motor cycle he acquired a
+motor boat, and in that he and Ned went through some strenuous
+times on Lake Carlopa, near Tom's home. Then followed an airship,
+for Tom got that craze, and in the book concerning that machine I
+related some of the things that happened to him. He had even more
+wonderful adventures in his submarine, and with his electric
+runabout our hero was instrumental in saving a bank from ruin by
+making a trip in the speediest car on the road.
+
+After Tom Swift had sent his wireless message, and saved the
+castaways of Earthquake Island, he thought he would give up his
+inventive work for a time, and settle down to a life of ease and
+quiet.
+
+But the call of the spirit of adventure was still too strong for
+him to resist. That was why he sought out the diamond makers, and
+learned the secret of Phantom Mountain. And when he went to the
+Caves of Ice, and there saw his airship wrecked, Tom was well-nigh
+discouraged, But he managed to get back to civilization, and later
+undertook a journey to elephant land, with his powerful electric
+rifle.
+
+Marvelous adventures underground did Tom Swift have when he went
+to the City of Gold, and I have set down some of them in the book
+bearing the latter title. Later on he sought the platinum treasure
+in his air glider. And when Tom was taken captive, in giant land,
+only his speedy airship saved him from a hard fate.
+
+By this time moving pictures were beginning to occupy a large
+place in the scientific, as well as the amusement world, and Tom
+invented a Wizard Camera which did excellent work. Then came the
+need of a powerful light, to enable Uncle Sam's custom officers on
+the border to detect the smugglers, and Tom was successful in
+making his apparatus.
+
+He thought he would take a rest after that, but with the opening
+of the Panama Canal came the need of powerful guns to protect that
+important waterway, and Tom made a Giant Cannon, which enabled the
+longest shots on record to be fired.
+
+Now, some months had passed, after the successful trial of the big
+weapon, and Tom longed for new activities. He found them in the
+idea of a photo telephone, and he and his father were just talking
+of this when interrupted by the accident to the birdman on the
+roof of the Swift home.
+
+"Have you got that ladder, Rad?" cried the young inventor,
+anxiously, as he saw the dangerous position of the man from the
+airship.
+
+"Yas, sah, Massa Tom! I'se a-camin' wif it!"
+
+"And where's Koku? We'll need him!"
+
+"He's a-camin', too!"
+
+"Here Koku!" exclaimed a deep voice, and a big man came running
+around the corner of the house. "What is it, Master?"
+
+"We must get him down, Koku!" said Tom, simply. "I will go up on
+the roof. You had better come, too. Rad, go in the house and get a
+mattress from the bed. Put it down on the ground where he's likely
+to fall. Lively now!"
+
+"Yas, sah, Massa Tom!"
+
+"Me git my own ladder--dat one not strong 'nuff!" grunted Koku,
+who did not speak very good English. He had a very strong ladder,
+of his own make, built to hold his enormous bulk, and this he soon
+brought and placed against the side of the house.
+
+Meanwhile Tom and his father had raised the one Eradicate had
+brought, though Tom did most of the lifting, for his father was
+elderly, and had once suffered from heart trouble.
+
+"We're coming for you!" cried the young inventor as he began to
+ascend the ladder, at the same time observing that the giant was
+coming with his. "Can you hold on a little longer?"
+
+"Yes, I guess so. But I dare not move for fear the propellers will
+strike me."
+
+"I see. I'll soon shut off the motor," said Tom. "What happened,
+anyhow?"
+
+"Well, I was flying over your house. I was on my way to pay you a
+visit, but I didn't intend to do it in just this way," and the
+birdman smiled grimly. "I didn't see your wireless aerials until I
+was plumb into them, and then it was too late. I hope I haven't
+damaged them any."
+
+"Oh, they are easily fixed," said Tom. "I hope you and your
+biplane are not damaged. This way, Koku!" he called to the giant.
+
+"Say, is--is he real, or am I seeing things?" asked the aviator,
+as he looked at the big man.
+
+"Oh, he's real, all right," laughed Tom. "Now, then, I'm going to
+shut off your motor, and then you can quit hugging that chimney,
+and come down."
+
+"I'll be real glad to," said the birdman.
+
+Making his way cautiously along the gutters of the roof, Tom
+managed to reach the motor controls. He pulled out the electrical
+switch, and with a sort of cough and groan the motor stopped. The
+big propellers ceased revolving, and the aviator could leave his
+perch in safety.
+
+This he did, edging along until he could climb down and meet Tom,
+who stood near the ladder.
+
+"Much obliged," said the birdman, as he shook hands with Tom. "My
+name is Grant Halling. I'm a newcomer in Mansburg," he added,
+naming a town not far from Shopton. "I know you by reputation, so
+you don't need to introduce yourself."
+
+"Glad to meet you," said the young inventor, cordially. "Rather a
+queer place to meet a friend," he went on with a laugh and a
+glance down to the ground. "Can you climb?"
+
+"Oh, yes, I'm used to that. The next thing will be to get my
+machine down."
+
+"Oh, we can manage that with Koku's help," spoke Tom. "Koku, get
+some ropes, and see what you and Rad can do toward getting the
+aeroplane down," he added to the giant. "Let me know if you need
+any help."
+
+"Me can do!" exclaimed the big man. "Me fix him!"
+
+Tom and Mr. Halling made their way down the ladder, while the
+giant proceeded to study out a plan for getting the airship off
+the roof.
+
+"You say you were coming over to see me, when you ran into my
+wireless aerials?" asked Tom, curiously, when he had introduced
+his father to the birdman.
+
+"Yes," went on Mr. Halling. "I have been having some trouble with
+my motor, and I thought perhaps you could tell me what was wrong.
+My friend, Mr. Wakefield Damon, sent me to you."
+
+"What! Do you know Mr. Damon?" cried Tom.
+
+"I've known' him for some years. I met him in the West, but I
+hadn't seen him lately, until I came East. He sent me to see you,
+and said you would help me."
+
+"Well, any friend of Mr. Damon's is a friend of mine!" exclaimed
+Tom, genially. "I'll have a look at your machine as soon as Koku
+gets it down. How is Mr. Damon, anyhow? I haven't seen him in over
+two weeks."
+
+"I'm sorry to say he isn't very well, Mr. Swift."
+
+"Is he ill? What is the trouble?"
+
+"He isn't exactly ill," went on Mr. Halling, "but he is fretting
+himself into a sickness, worrying over his lost fortune."
+
+"His lost fortune!" cried Tom, in surprise at the bad news
+concerning his friend. "I didn't know he had lost his money!"
+
+"He hasn't yet, but he's in a fair way to, he says. It's something
+about bad investments, and he did speak of the trickery of one
+man, I didn't get the particulars. But he certainly feels very
+badly over it."
+
+"I should think he would," put in Mr. Swift. "Tom, we must look
+into this. If we can help Mr. Damon--"
+
+"We certainly will," interrupted Tom. "Now come in the house, Mr.
+Halling. I'm sure you must be quite shaken up by your upset."
+
+"I am, to tell you the truth, though it isn't the first accident
+I've had in my airship."
+
+They were proceeding toward the house, when there came a cry from
+Koku, who had fastened a rope about the airship to lower it.
+
+"Master! Master!" cried the giant. "The rope am slippin'. Grab the
+end of it!"
+
+
+
+
+
+CHAPTER III
+
+TOM'S FAILURE
+
+
+"Come on!" cried Tom, quickly, as, turning', he saw the accident
+about to happen. "Your craft will surely be smashed if she slips
+to the ground, Mr. Halling!"
+
+"You're right! This seems to be my unlucky day!" The birdman,
+limping slightly from his fall, hurried with Tom to where a rope
+trailed on the ground. Koku had fastened one end to the airship,
+and had taken a turn of the cable about the chimney. He had been
+lowering the biplane to the ground, but he had not allowed for its
+great weight, and the rope had slipped from his big hands.
+
+But Tom and Mr. Halling were just in time. They grabbed the
+slipping hempen strands, and thus checked the falling craft until
+Koku could get a better grip.
+
+"All right now," said the giant, when he had made fast the rope.
+"Me fix now. Master can go."
+
+"Think he can lower it?" asked Mr. Halling, doubtfully.
+
+"Oh, surely," said Tom. "Koku's as strong as a horse. You needn't
+worry. He'll get it down all right. But you are limping."
+
+"Yes, I jammed my leg a little."
+
+"Don't you want a doctor?"
+
+"Oh, no, not for a little thing like that."
+
+But Tom insisted on looking at his new friend's wound, and found
+quite a cut on the thigh, which the young inventor insisted on
+binding up.
+
+"That feels better," said the birdman, as he stretched out on a
+couch. "Now if you can look my machine over, and tell me what's
+the matter with it, I'll be much obliged to you, and I'll get on
+my way."
+
+"Not quite so fast as that!" laughed Tom. "I wouldn't want to see
+you start off with your lame leg, and certainly I would not want
+to see you use your aircraft after what she's gone through, until
+we've given her a test. You can't tell what part you might have
+strained."
+
+"Well, I suppose you are right. But I think I'd better go to a
+hotel, or send for an auto and go home."
+
+"Now you needn't do anything of the kind," spoke Tom, hospitably.
+"We've got lots of room here, and for that matter we have plenty
+of autos and airships, too, as well as a motor boat. You just rest
+yourself here. Later we'll look over your craft."
+
+After dinner, when Mr. Halling said he felt much better, Tom
+agreed to go out with him and look at the airship. As he feared,
+he found several things the matter with it, in addition to the
+motor trouble which had been the cause for Mr. Halling's call on
+the young inventor.
+
+"Can she be fixed?" asked the birdman, who explained that, as yet,
+he was only an amateur in the practice of flying.
+
+"Oh, yes, we can fix her up for you," said Tom. "But it will take
+several days. You'll have to leave it here."
+
+"Well, I'll be glad to do that, for I know she will be all the
+better when you get through with her. But I think I am able to go
+on home now, and I really ought to. There is some business I must
+attend to."
+
+"Speaking of business," remarked Tom, "can you tell me anything
+more of Mr. Damon's financial troubles?"
+
+"No, not much. All I know is that when I called on him the other
+day I found him with his check book out, and he was doing a lot of
+figuring. He looked pretty blue and downcast, I can tell you."
+
+"I'm sorry about that," spoke Tom, musingly. "Mr. Damon is a very
+good friend of mine, and I'd do anything to help him. I certainly
+wouldn't like to see him lose his fortune. Bad investments, you
+say it was?"
+
+"Partly so, and yet I'm inclined to think if he does lose his
+money it will be due to some trickery. Mr. Damon is not the man to
+make bad investments by himself."
+
+"Indeed he is not," agreed Tom. "You say he spoke of some man?"
+
+"Yes, but not definitely. He did not mention any name. But Mr.
+Damon was certainly quite blue."
+
+"That's unlike him," remarked Tom. "He is usually very jolly. He
+must be feeling quite badly. I'll go over and have a talk with
+him, as soon as I can."
+
+"Do. I think he would appreciate it. And now I must see about
+getting home."
+
+"I'll take you in one of my cars," said Tom, who had several
+automobiles. "I don't want to see you strain that injured leg of
+yours."
+
+"You're very good--especially after I tangled up your wireless
+aerials; but I didn't see them until I was right into them,"
+apologized Mr. Halling.
+
+"They're a new kind of wire," said Tom, "and are not very plain to
+see. I must put up some warning signs. But don't worry about
+damaging them. They were only up temporarily anyhow, and I was
+going to take them down to arrange for my photo telephone."
+
+"Photo telephone, eh? Is that something new?"
+
+"It will be--if I can get it working," said Tom, with a smile.
+
+A little later Tom had taken Mr. Halling home, and then he set
+about making arrangements for repairing the damaged airship. This
+took him the better part of a week, but he did not regret the
+time, for while he was working he was busy making plans for his
+newest invention--the photo telephone.
+
+One afternoon, when Tom had completed the repairs to the airship,
+and had spent some time setting up an experimental telephone line,
+the young inventor received a call from his chum, Ned Newton.
+
+"Well, well, what are you up to now?" asked Ned, as he saw his
+chum seated in a booth, with a telephone receiver to his ear,
+meanwhile looking steadily at a polished metal plate in front of
+him. "Trying to hypnotize yourself, Tom?"
+
+"Not exactly. Quiet, Ned, please. I'm trying to listen."
+
+Ned was too familiar with his chum's work to take offense at this.
+The young banker took a seat on a box, and silently watched Tom.
+The inventor shifted several switches, pressed one button after
+another, and tilted the polished metal plate at different angles.
+Then he closed the door of the little telephone booth, and Ned,
+through the ground glass door, saw a light shining.
+
+"I wonder what new game Tom is up to?" Ned mused.
+
+Presently the door opened, and Tom stuck out his head.
+
+"Ned, come here," he invited. "Look at that metal plate and see if
+you can notice anything on it. I've been staring at it so steadily
+that my eyes are full of sticks. See what you can make out."
+
+"What is this?" asked Ned. "No trick; is it? I won't be blown up,
+or get my eyes full of pepper; will I?"
+
+"Nonsense! Of course not. I'm trying to make a photo telephone. I
+have the telephone part down pat, but I can't see anything of the
+photo image. See if you can."
+
+Ned stared at the polished plate, while Tom did things to it,
+making electrical connections, and tilting it at various angles.
+
+"See anything, Ned?" asked Tom.
+
+The other shook his head.
+
+"Whom am I supposed to see?" he asked.
+
+"Why, Koku is at the other end of the wire. I'm having him help
+me."
+
+Ned gazed from the polished plate out of a side window of the
+shop, into the yard.
+
+"Well, that Koku is certainly a wonderful giant," said Ned, with a
+laugh.
+
+"How so?" asked Tom.
+
+"Why he can not be in two places at once. You say he ought to be
+at the other end of this wire, and there he is out there, spading
+up the garden."
+
+Tom stared for a second and then exclaimed:
+
+"Well, if that isn't the limit! I put him in the telephone booth
+in the machine shop, and told him to stay there until I was
+through. What in the world is he doing out there?"
+
+"Koku!" he called to the giant, "why didn't you stay at the
+telephone where I put you? Why did you run away?"
+
+"Ha!" exclaimed the giant, who, for all his great size was a
+simple chap, "little thing go 'tick-tick' and then 'clap-clap!'
+Koku no like--Koku t'ink bad spirit in telumfoam--Koku come out!"
+
+"Well, no wonder I couldn't see any image on the plate!" exclaimed
+Tom. "There was nobody there. Now, Ned, you try it; will you,
+please?"
+
+"Sure. Anything to oblige!"
+
+"Then go in the other telephone booth. You can talk to me on the
+wire. Say anything you like--the telephone part is all right. Then
+you just stand so that the light in the booth shines on your face.
+The machine will do the rest--if it works."
+
+Ned hurried off and was soon talking to his chum over the wire
+from the branch telephone in the machine shop. Ned stood in the
+glare of an electric light, and looked at a polished plate similar
+to the one in the other booth.
+
+"Are you there, Ned?" asked Tom.
+
+"Yes, I'm here."
+
+"Is the light on?"
+
+"Yes."
+
+"And you're looking at the plate?"
+
+"Sure. Can you see any reflection in your plate?"
+
+"No, not a thing," answered Tom, and there was great
+discouragement in his voice. "The thing is a failure, Ned. Come on
+back," and the young banker could hear his chum hang up the
+telephone receiver at the other end.
+
+"That's too bad," murmured Ned, knowing how Tom must feel. "I'll
+have to cheer him up a bit."
+
+
+
+
+
+CHAPTER IV
+
+RUN DOWN
+
+
+When Ned Newton got back to where Tom sat in the small telephone
+booth, the young banker found his chum staring rather moodily at
+the polished metal plate on the shelf that held the talking
+instrument.
+
+"So it was no go; eh, Tom?"
+
+"No go at all, Ned, and I thought sure I had it right this time."
+
+"Then this isn't your first experiment?"
+
+"Land no! I've been at it, off and on, for over a month, and I
+can't seem to get any farther. I'm up against a snag now, good and
+hard."
+
+"Then there wasn't any image on your plate?"
+
+"Not a thing, Ned. I don't suppose you caught any glimpse of me in
+your plate?" asked Tom, half hopefully.
+
+"No. I couldn't see a thing. So you are going to try and make this
+thing work both ways, are you?"
+
+"That's my intention, But I can fix it so that a person can
+control the apparatus at his end, and only see the person he is
+talking to, not being seen himself, unless he wishes it. That is,
+I hope to do that. Just now nobody can see anybody," and Tom
+sighed.
+
+"Give it up," advised Ned. "It's too hard a nut to crack, Tom!"
+
+"Indeed, I'll not give it up, Ned! I'm going to work along a new
+line. I must try a different solution of selenium on the metal
+plate. Perhaps I may have to try using a sensitized plate, and
+develop it later, though I do want to get the machine down so you
+can see a perfect image without the need of developing. And I
+will, too!" cried Tom. "I'll get some new selenium."
+
+Eradicate, who came into the shop just then, heard the end of
+Tom's remarks. A strange look came over his honest black face, and
+he exclaimed:
+
+"What all am dat, Massa Tom? Yo'ah gwine t' bring de new millenium
+heah? Dat's de end of de world, ain't it-dat millenium? Golly!
+Dish yeah coon neber 'spected t' lib t' see dat. De millenium! Oh
+mah landy!"
+
+"No, Rad!" laughed Tom. "I was speaking about selenium, a sort of
+metallic combination that is a peculiar conductor of electricity.
+The more light that shines on it the better conductor it is, and
+the less light, the poorer."
+
+"It must be queer stuff," said Ned.
+
+"It is," declared Tom. "I think it is the only thing to use in
+this photo telephone experiment, though I might try the metal
+plate method, as they did between Monte Carlo and Paris. But I am
+not trying to make newspaper pictures."
+
+"What is selenium, anyhow?" asked Ned. "Remember, Tom, I'm not up
+on this scientific stuff as you are."
+
+"Selenium," went on Tom, "was discovered in 1817, by J. J.
+Berzelius, and he gave it that name from the Greek word for moon,
+on account of selenium being so similar, in some ways, to
+tellurium. That last is named after the Latin word tellus, the
+earth."
+
+"Do they dig it?" Ned wanted to know.
+
+"Well, sometimes selenium is found in combination with metals, in
+the form of selenides, the more important minerals of that kind
+being eucharite, crooksite, clausthalite, naumannite and zorgite--"
+
+"Good night!" interrupted Ned, with a laugh, holding up his hands.
+"Stop it, Tom!" he pleaded. "You'll give me a headache with all
+those big words."
+
+"Oh, they're easy, once you get used to them," said the young
+inventor, with a smile. "Perhaps it will be easier if I say that
+sometimes selenium is found in native sulphur. Selenium is usually
+obtained from the flue-dust or chamber deposits of some factory
+where sulphuric acid is made. They take this dust and treat it
+with acids until they get the pure selenium. Sometimes selenium
+comes in crystal forms, and again it is combined with various
+metals for different uses."
+
+"There's one good thing about it. There are several varieties, and
+I'll try them all before I give up."
+
+"That's the way to talk!" cried Ned. "Never say die! Don't give up
+the ship, and all that. But, Tom, what you need now is a little
+fun. You've been poking away at this too long. Come on out on the
+lake, and have a ride in the motor boat. It will do you good. It
+will do me good. I'm a bit rusty myself--been working hard lately.
+Come on--let's go out on the lake."
+
+"I believe I will!" exclaimed Tom, after thinking it over for a
+moment. "I need a little fresh air. Sitting in that telephone
+booth, trying to get an image on a plate, and not succeeding, has
+gotten on my nerves. I want to write out an order for Koku to take
+to town, though. I want to get some fresh selenium, and then I'm
+going to make new plates."
+
+Tom made some memoranda, and then, giving Koku the order for the
+chemist, the young inventor closed up his shop, and went with Ned
+down to Lake Carlopa, where the motor boat was moored.
+
+This was not the same boat Tom had first purchased, some years
+ago, but a comparatively new and powerful craft.
+
+"It sure is one grand little day for a ride," remarked Ned, as he
+got in the craft, while Tom looked over the engine.
+
+"Yes, I'm glad you came over, and routed me out," said the young
+inventor. "When I get going on a thing I don't know enough to
+stop. Oh, I forgot something!"
+
+"What?" asked Ned.
+
+"I forgot to leave word about Mr. Railing's airship. It's all
+fixed and ready for him, but I put on a new control, and I wanted
+to explain to him about it. He might not know how to work it. I
+left word with father, though, that if he came for it he must not
+try it until he had seen me. I guess it will be all right. I don't
+want to go back to the house now."
+
+"No, it's too far," agreed Ned.
+
+"I have it!" exclaimed Tom. "I'll telephone to dad from here, not
+to let Halling go up until I come back. He may not come for his
+machine; but, if he does, it's best to be on the safe side Ned."
+
+"Oh, sure."
+
+Accordingly, Tom 'phoned from his boat-house, and Mr. Swift
+promised to see the bird-man if he called. Then Ned and Tom gave
+themselves up to the delights of a trip on the water.
+
+The Kilo, which name Tom had selected for his new craft, was a
+powerful boat, and comfortable. It swept on down the lake, and
+many other persons, in their pleasure craft, turned to look at
+Tom's fine one.
+
+"Lots of folks out to-day," observed Ned, as they went around a
+point of the shore.
+
+"Yes, quite a number," agreed Tom, leaning forward to adjust the
+motor. "I wonder what's got into her?" he said, in some annoyance,
+as he made various adjustments. "One of the cylinders is missing."
+
+"Maybe it needs a new spark plug," suggested Ned.
+
+"Maybe. Guess I'll stop and put one in."
+
+Tom slowed down the motor, and headed his boat over toward shore,
+intending to tie up there for a while.
+
+As he shifted the wheel he heard a cry behind him, and at the same
+time a hoarse, domineering voice called out:
+
+"Here, what do you mean, changing your course that way? Look out,
+or I'll run you down! Get out of my way, you land-lubber, you!"
+
+Startled, Ned and Tom turned. They saw, rushing up on them from
+astern, a powerful red motor boat, at the wheel of which sat a
+stout man, with a very florid face and a commanding air.
+
+"Get out of my way!" he cried. "I can't stop so short! Look out,
+or I'll run you down!"
+
+Tom, with a fierce feeling of resentment at the fellow, was about
+to shift the course of the Kilo, but he was too late.
+
+A moment later there came a smashing blow on the stern port
+quarter and the Kilo heeled over at a dangerous angle, while, with
+a rending, splintering sound of wood, the big red motorboat swept
+on past Tom and Ned, her rubstreak grinding along the side of the
+Kilo.
+
+
+
+
+
+CHAPTER V
+
+SHARP WORDS
+
+
+"Great Scott, Tom! What happened?"
+
+"I know as much as you, Ned. That fellow ran us down, that's all."
+
+"Are we leaking?" and with this question Ned sprang from his place
+near the bow, and looked toward the stern, where the heaviest blow
+had been struck.
+
+The Kilo had swung back to an even keel again, but was still
+bobbing about on the water.
+
+"Any hole there?" cried Tom, as he swung the wheel over to point
+his craft toward shore, in case she showed a tendency to sink.
+
+"I can't see any hole," answered Ned. "But water is coming in
+here."
+
+"Then there's a leak all right! Probably some of the seams are
+opened, or it may be coming in around the shaft stuffing-box.
+Here, Ned, take the wheel, and I'll start up the engine again,"
+for with the blow the motor had stopped.
+
+"What are you going to do?" asked Ned, as he again made his way
+forward.
+
+"Take her to shore, of course. It's deep out here and I don't want
+her to go down at this point."
+
+"Say, what do you think of that fellow, anyhow, Tom?"
+
+"I wouldn't like to tell you. Look, he's coming back."
+
+This was so, for, as the boys watched, the big red motor boat had
+swung about in a circle and was headed for them.
+
+"I'll tell him what I think of him, at any rate," murmured Tom, as
+he bent over his motor. "And, later on, I'll let the lawyers talk
+to him."
+
+"You mean you'll sue him, Tom?"
+
+"Well, I'm certainly not going to let him run into me and spring a
+leak, for nothing. That won't go with me!"
+
+By this time Tom had the motor started, but he throttled it down
+so that it just turned the propeller. With it running at full
+speed there was considerable vibration, and this would further
+open the leaking seams. So much water might thus be let in that
+the craft could not be gotten ashore.
+
+"Head her over, Ned," cried Tom, when he found he had sufficient
+headway. "Steer for Ramsey's dock. There's a marine railway next
+to him, and I can haul her out for repairs."
+
+"That's the talk, Tom!" cried his chum.
+
+By this time the big, red motor boat was close beside Tom's craft.
+
+The man at the wheel, a stout-bodied and stout-faced man, with a
+complexion nearly the color of his boat, glared at the two young
+men.
+
+"What do you fellows mean?" called out the man, in deep booming
+tones--tones that he tried to make imposing, but which, to the
+trained ears of Tom and Ned, sounded only like the enraged bellow
+of some bully. "What do you mean, I say? Getting on my course like
+that!"
+
+Ned could see Tom biting his lips, and clenching his hands to keep
+down his temper. But it was too much. To be run into, and then
+insulted, was more than Tom could stand.
+
+"Look here!" he cried, standing up and facing the red-faced man,
+"I don't know who you are, and I don't care. But I'll tell you one
+thing--you'll pay for the damage you did to my boat!"
+
+"I'll pay for it? Come, that's pretty good! Ha! Ha!" laughed the
+self-important man. "Why, I was thinking of making a complaint
+against you for crossing my course that way. If I find my boat is
+damaged I shall certainly do so anyhow. Have we suffered any
+damage, Snuffin?" and he looked back at a grimy-faced mechinician
+who was oiling the big, throbbing motor, which was now running
+with the clutch out.
+
+"No, sir, I don't think we're damaged, sir," answered the man,
+deferentially.
+
+"Well, it's a lucky thing for these land-lubbers that we aren't. I
+should certainly sue them. The idea of crossing my course the way
+they did. Weren't they in the wrong, Snuffin?"
+
+The man hesitated for a moment, and glanced at Tom and Ned, as
+though asking their indulgence.
+
+"Well, I asked you a question, Snuffin!" exclaimed the red-faced
+man sharply.
+
+"Yes--yes, sir, they shouldn't have turned the way they did,"
+answered the man, in a low voice.
+
+"Well, of all the nerve!" murmured Tom, and stopped his motor.
+Then, stepping to the side of his disabled and leaking boat, he
+exclaimed:
+
+"Look here! Either you folks don't know anything about navigation
+rules, or you aren't heeding them. I had a perfect right to turn
+and go ashore when I did, for I found my engine was out of order,
+and I wanted to fix it. I blew the usual signal on the whistle,
+showing my intention to turn off my course, and if you had been
+listening you would have heard it."
+
+"If you had even been watching you would have seen me shift, and
+then, coming on at the speed you did, it was your place to warn me
+by a whistle, so that I could keep straight on until you had
+passed me."
+
+"But you did not. You kept right on and ran into me, and the only
+wonder is that you didn't sink me. Talk about me getting in your
+way! Why, you deliberately ran me down after I had given the right
+signal. I'll make a complaint against you, that's what I will."
+
+If possible the red-faced man got even more rosy than usual. He
+fairly puffed up, he was so angry.
+
+"Listen to that, will you, Snuffin!" he cried. "Listen to that! He
+says he blew his whistle to tell us he was going to turn in."
+
+"That's what I did!" said Tom, calmly.
+
+"Preposterous! Did you hear it, Snuffin?" puffed the important
+man.
+
+"Yes--yes, I think I did, sir," answered the machinist, in a
+hesitating voice.
+
+"You did? What! You mean to tell me you heard their whistle?"
+
+"Yes--yes, sir!"
+
+"Why--why--er--I--" the big man puffed and blew, but seemed to
+find no words in which to express himself. "Snuffin, I'll have a
+talk with you when we get home," he finally said. most
+significantly. "The idea of saying you heard a whistle blown!
+There was nothing of the kind! I shall make a complaint against
+these land-lubbers myself. Do you know who they are, Snuffin?"
+
+"Yes--yes, sir," was the answer, as the man glanced at Tom. "At
+least I know one of them, sir."
+
+"Very good. Give me his name. I'll attend to the rest."
+
+Tom looked at the big man sharply. He had never seen him before,
+as far as he could recall. As for the machinist, the young
+inventor had a dim recollection that once the man might have
+worked in his shop.
+
+"Go ahead, Snuffin!" said the big man, mopping his face with a
+large silk handkerchief, which, even at that distance, gave out a
+powerful perfume. "Go ahead, Snuffin, and we will settle this
+matter later," and, adjusting a large rose in his buttonhole, the
+self-important individual took his place on the cushioned seat at
+the wheel, while the big red motor boat drew off down the river.
+
+"Well, of all the nerve!" gasped Ned. "Isn't he the limit?"
+
+"Never mind," spoke Tom, with a little laugh. "I'm sorry I lost my
+temper, and even bothered to answer him. We'll let the lawyers do
+the rest of the talking. Take the wheel, Ned."
+
+"But are you going to let him get away like this, Tom? Without
+asking him to pay for the damage to your boat, when he was clearly
+in the wrong?"
+
+"Oh, I'll ask him to pay all right; but I'll do it the proper way.
+Now come on. If we stay here chinning much longer the Kilo will go
+down. I must find out who he is. I think I know Snuffin--he used
+to work for me, I now recall."
+
+"Don't you know who that big man is?" asked Ned, as he took the
+wheel, while Tom again started the motor. The water was now almost
+up to the lower rim of the fly wheel.
+
+"No; who is he?" asked Tom.
+
+"Shallock Peters."
+
+"Well, I know as much as I did before," laughed Tom. "That doesn't
+tell me anything."
+
+"Why, I thought everybody in the town knew Shallock Peters," went
+on Ned. "He tried to do some business with our bank, but was
+turned down. I hear he's gone to the other one, though. He's what
+we call a get-rich-quick schemer, Tom--a promoter."
+
+"I thought he acted like that sort of a character."
+
+"Well, that's what he is. He's got half a dozen schemes under way,
+and he hasn't been in town over a month. I wonder you haven't seen
+or heard of him."
+
+"I've been too busy over my photo telephone."
+
+"I suppose so. Well, this fellow Peters struck Shopton about a
+month ago. He bought the old Wardell homestead, and began to show
+off at once. He's got two autos, and this big motor boat. He
+always goes around with a silk hat and a flower in his buttonhole.
+A big bluff--that's what he is."
+
+"He acted so to me," was Tom's comment. "Well, he isn't going to
+scare me. The idea! Why, he seemed to think we were in the wrong;
+whereas he was, and his man knew it, too."
+
+"Yes, but the poor fellow was afraid to say so. I felt sorry for
+him."
+
+"So did I," added Tom. "Well, Kilo is out of commission for the
+present. Guess we'll have to finish our outing by walking, Ned."
+
+"Oh, I don't mind. But it makes me mad to have a fellow act the
+way he did."
+
+"Well, there's no good in getting mad," was Tom's smiling
+rejoinder. "We'll take it out of him legally. That's the best way
+in the end. But I can't help saying I don't like Mr. Shallock
+Peters."
+
+"And I don't either," added Ned.
+
+
+
+
+
+CHAPTER VI
+
+A WARNING
+
+
+"There, she's about right now, Ned. Hold her there!"
+
+"Aye, aye, Captain Tom!"
+
+"Jove, she's leaking like a sieve! We only got her here just in
+time!"
+
+"That's right," agreed Ned.
+
+Tom and his chum had managed to get the Kilo to Ramsey's dock, and
+over the ways of the inclined marine railway that led from the
+shop on shore down into the river. Then, poling the craft along,
+until she was in the "cradle," Ned held her there while Tom went
+on shore to wind up the windlass that pulled the car, containing
+the boat, up the incline.
+
+"I'll give you a hand, as soon as I find she sets level," called
+Ned, from his place in the boat.
+
+"All right--don't worry. There are good gears on this windlass,
+and she works easy," replied Tom.
+
+In a short time the boat was out of the water, but, as Tom grimly
+remarked, "the water was not out of her," for a stream poured from
+the stuffing-box, through which the propeller shaft entered, and
+water also ran out through the seams that had been opened by the
+collision.
+
+"Quite a smash, Tom," observed the boat repairer, when he had come
+out to look over the Kilo. "How'd it happen?"
+
+"Oh, Shallock Peters, with his big red boat, ran into us!" said
+Ned, sharply.
+
+"Ha, Peters; eh?" exclaimed the boatman. "That's the second craft
+he's damaged inside a week with his speed mania. There's Bert
+Johnson's little speeder over there," and he pointed to one over
+which some men were working. "Had to put a whole new stern in her,
+and what do you think that man Peters did?"
+
+"What?" asked Tom, as he bent down to see how much damage his
+craft had sustained.
+
+"He wouldn't pay young Johnson a cent of money for the repairs,"
+went on Mr. Houston, the boatman. "It was all Peters's fault,
+too."
+
+"Couldn't he make him pay?" asked Tom.
+
+"Well, young Johnson asked for it--no more than right, too; but
+Peters only sneered and laughed at him."
+
+"Why didn't he sue?" asked Ned.
+
+"Costs too much money to hire lawyers, I reckon. So he played you
+the same trick; eh. Tom?"
+
+"Pretty much, yes. But he won't get off so easily, I can tell you
+that!" and there was a grim and determined look on the face of the
+young inventor. "How long will it take to fix my boat, Mr.
+Houston?"
+
+"Nigh onto two weeks, Tom. I'm terrible rushed now."
+
+Tom whistled ruefully.
+
+"I could do it myself quicker, if I could get her back to my
+shop," he said. "But she'd sink on the home trip. All right, do
+the best you can, Mr. Houston."
+
+"I will that, Tom."
+
+The two chums walked out of the boat-repair place.
+
+"What are you going to do, Tom?" asked Ned, as they strolled
+along.
+
+"Well, since we can't go motor boating, I guess I may as well go
+back and see if that new supply of selenium has come. I do want to
+get my photo telephone working, Ned."
+
+"And that's all the outing you're going to take--less than an
+hour!" exclaimed Ned, reproachfully.
+
+"Oh, well, all you wanted to do was to get me out of a rut, as you
+called it," laughed Tom. "And you've done it--you and Mr. Peters
+together. It jolted up my brain, and I guess I can think better
+now. Come on back and watch me tinker away, Ned."
+
+"Not much! I'm going to stay out and get some fresh air while I
+can. You'd better, too."
+
+"I will, later."
+
+So Tom turned back to his workshop, and Ned strolled on into the
+country, for his day's work at the bank was over. And for some
+time after that--until far into the night--Tom Swift worked at the
+knotty problem of the photo telephone.
+
+But the young inventor was baffled. Try as he might, he could not
+get the image to show on the metal plate, nor could he get any
+results by using a regular photographic plate, and developing it
+afterward.
+
+"There is something wrong with the transmission of the light waves
+over the wire," Tom confessed to his father.
+
+"You'll never do it, Tom," said the aged inventor. "You are only
+wasting a whole lot of time."
+
+"Well, as I haven't anything else to do now, it isn't much loss,"
+spoke Tom, ruefully. "But I'm going to make this work, Dad!"
+
+"All right, son. It's up to you. Only I tell you it can't be
+done."
+
+Tom, himself, was almost ready to admit this, when, a week later,
+he seemed to be no nearer a solution of the problem than he was at
+first. He had tried everything he could think of, and he had
+Eradicate and Koku, the giant, almost distracted, by making them
+stay in small telephone booths for hours at a time, while the
+young inventor tried to get some reflection of one face or the
+other to come over the wire.
+
+Koku finally got so nervous over the matter, that he flatly
+refused to "pose" any longer, so Tom was forced to use Eradicate.
+As for that elderly man of all work, after many trials, all
+unsuccessful, he remarked:
+
+"Massa Tom, I reckon I knows what's wrong."
+
+"Yes, Rad? Well, what is it?"
+
+"Mah face am too black--dat's de trouble. You done want a white-
+complected gen'man to stand in dat booth an' look at dat lookin'
+glass plate. I'se too black! I suah is!"
+
+"No, that isn't it, Rad," laughed Tom, hopelessly. "If the thing
+works at all it will send a black man's face over the wire as well
+as a white man's. I guess the truth of it is that you're like
+Koku. You're getting tired. I don't know as I blame you. I'm
+getting a bit weary myself. I'm going to take a rest. I'll send
+for another kind of selenium crystals I've heard of, and we'll try
+them. In the meanwhile--I'll take a little vacation."
+
+"Get out my small airship, Rad, and I'll take a little flight."
+
+"Dat's de way to talk, Massa Tom," was the glad rejoinder.
+
+"I'm going over to see Mr. Damon, Father," announced Tom to Mr.
+Swift a little later, when his speedy monoplane was waiting for
+him. "I haven't seen him in some time, and I'd like to get at the
+truth of what Mr. Halling said about Mr. Damon's fortune being in
+danger. I'll be back soon."
+
+"All right, Tom. And say--"
+
+"Yes, Dad, what is it?" asked Tom, as he paused in the act of
+getting in the seat.
+
+"If he wants any ready cash, you know we've got plenty."
+
+"Oh, sure. I was going to tell him we'd help him out."
+
+Then, as Koku spun the propeller blades, Tom grasped the steering
+wheel, and, tilting the elevating rudder, he was soon soaring into
+the air, he and his craft becoming smaller and smaller as they
+were lost to sight in the distance, while the rattle and roar of
+the powerful motor became fainter.
+
+In a comparatively short time Tom had made a successful landing in
+the big yard in front of Mr. Damon's house, and, walking up the
+path, kept a lookout for his friend.
+
+"I wonder why he didn't come out to meet me?" mused Tom, for
+usually when the eccentric man heard the throbbing of Tom's motor,
+he was out waiting for the young inventor. But this time it was
+not the case.
+
+"Is Mr. Damon in?" Tom asked of the maid who answered his ring.
+
+"Yes, Mr. Swift. You'll find him in the library," and she ushered
+him in.
+
+"Oh, hello, Tom," greeted Mr. Damon, but the tone was so listless,
+and his friend's manner so gloomy that the young inventor was
+quite embarrassed.
+
+"Have a chair," went on Mr. Damon. "I'll talk to you in a minute,
+Tom. I've got to finish this letter, and it's a hard one to write,
+let me tell you."
+
+Now Tom was more astonished than ever. Not once had Mr. Damon
+"blessed," anything, and when this did not happen Tom was sure
+something was wrong. He waited until his friend had sealed the
+letter, and turned to him with a sigh. Then Tom said boldly:
+
+"Mr. Damon, is it true that you're having hard luck--in money
+matters?"
+
+"Why, yes, Tom, I'm afraid I am," was the quick answer. "But who
+told you?"
+
+"Grant Halling. He was over to get me to fix his airship," and Tom
+briefly related what had happened.
+
+"Oh, yes, I did mention the matter to him," went on Mr. Damon, and
+his tone was still listless. "So he told you; did he? Well,
+matters aren't any better, Tom. In fact, they're worse. I just had
+to write to a man who was asking for help, and I had to refuse
+him, though he needs it very much. The truth is I hadn't the
+money. Tom, I'm afraid I'm going to be a very poor man soon."
+
+"Impossible, Mr. Damon! Why, I thought your investments--"
+
+"I've made some bad ones of late, Tom. I've been pretty foolish,
+I'm afraid. I drew out some money I had in government bonds, and
+invested in certain stocks sold by a Mr. Shallock Peters."
+
+"Shallock Peters!" cried Tom, almost jumping out of his chair.
+"Why, I know him--I mean I've met him."
+
+"Have you, Tom? Well, then, all I've got to say is to steer clear
+of him, my boy. Don't have anything to do with him," and, with
+something of a return of his usual energy Mr. Damon banged his
+fist down on his desk. "Give him a wide berth, Tom, and if you see
+him coming, turn your back. He'd talk a miser into giving him his
+last cent. Keep away from Shallock Peters, Tom. Bless my necktie,
+he's a scoundrel, that's what he is!" and again Mr. Damon banged
+his desk forcibly.
+
+
+
+
+
+CHAPTER VII
+
+SOFT WORDS
+
+
+"Well, I'm glad of one thing!" exclaimed Tom, when the ink bottle
+and the paper cutter on Mr. Damon's desk had ceased rattling,
+because of the violence of the blow. "I'm glad of one thing."
+
+"What's that, Tom?" asked his friend.
+
+"I heard you bless something at last--the first time since I came
+in."
+
+"Oh!" and Mr. Damon laughed. "Well, Tom, I haven't been blessing
+things lately--that's a fact. I haven't had the heart for it.
+There are too many business complications. I wish I'd never met
+this Peters."
+
+"So do I," said Tom. "My motor boat would not have been damaged
+then."
+
+"Did he do that, Tom?"
+
+"He certainly did, and then he accused me of being at fault."
+
+"That would be just like him. Tell me about it, Tom."
+
+When the young inventor finished the story of the collision Mr.
+Damon sat silent for a moment. Then he remarked slowly:
+
+"That's just like Peters. A big bluff--that's what he is. I wish
+I'd discovered that fact sooner--I'd be money in pocket. But I
+allowed myself to be deceived by his talk about big profits. At
+first he seemed like a smart business man, and he certainly had
+fine recommendations. But I am inclined to believe, now, that the
+recommendations were forged."
+
+"What did he do to you, Mr. Damon?" asked Tom, with ready
+sympathy.
+
+"It's too complicated to go into details over, Tom, but to make a
+long story short, he got me to invest nearly all my fortune in
+some enterprises that, I fear, are doomed to failure. And if they
+do fail, I'll be a ruined man."
+
+"No, you won't!" exclaimed Tom. "That's one reason why I came here
+to-day. Father told me to offer you all the ready money you needed
+to get out of your trouble. How much do you need, Mr. Damon?"
+
+"Bless my collar button! That's like your father, Tom," and now
+Mr. Damon seemed more like his old self. "Bless my shoes, a man
+never knows who his real friends are until trouble comes. I can't
+say how I thank you and your father, Tom. But I'm not going to
+take advantage of him."
+
+"It wouldn't be taking any advantage of him, Mr. Damon. He has
+money lying idle, and he'd like to have you use it."
+
+"Well, Tom, I might use it, if I had only myself to think about.
+But there's no use in throwing good money after bad. If I took
+yours now this fellow Peters would only get it, and that would be
+the last of it."
+
+"No, Tom, thank you and your father just the same, but I'll try to
+weather the storm a bit longer myself. Then, if I do go down I
+won't drag anybody else with me. I'll hang on to the wreck a bit
+longer. The storm may blow over, or--or something may happen to
+this fellow Peters."
+
+"Has he really got you in his grip, Mr. Damon?"
+
+"He has, and, to a certain extent, it's my own fault. I should
+have been suspicious of him. And now, Tom, let me give you a
+further word of warning. You heard me say to steer clear of this
+Peters?"
+
+"Yes, and I'm going to. But I'm going to make him pay for damaging
+my boat, if I possibly can."
+
+"Maybe it would be wiser not to try that, Tom. I tell you he's a
+tricky man. And one thing more. I have heard that this man Peters
+makes a specialty of organizing companies to take up new
+inventions."
+
+"Is that so?" asked Tom, interestedly.
+
+"Yes, but that's as far as it goes. Peters gets the invention, and
+the man, out of whose brain it came, gets nothing."
+
+"In other words, he swindles them?"
+
+"That's it, Tom. If not in one way, then in another. He cheats
+them out of the profits of their inventions. So I want to warn you
+to be on the lookout."
+
+"Don't worry," said Tom. "Peters will get nothing from my father
+or me. We'll be on our guard. Not that I think he will try it, but
+it's just as well to be warned. I didn't like him from the moment
+he ran into me, and, now that I know what he has done to you, I
+like him still less. He won't get anything from me!"
+
+"I'm glad to hear you say so, Tom. I wish he'd gotten nothing out
+of me."
+
+"Are you sure you won't let my father help you, financially, Mr.
+Damon?"
+
+"No, Tom, at least not for the present. I'm going to make another
+fight to hold on to my fortune. If I find I can't do it alone,
+then I'll call on you. I'm real glad you called. Bless my
+shoestring! I feel better now."
+
+"I'm glad of it," laughed Tom, and he saw that his friend was in a
+better state of mind, as his "blessings" showed.
+
+Tom remained for a little longer, talking to Mr. Damon, and then
+took his leave, flying back home in the airship.
+
+"Gen'man t' see yo', Massa Tom," announced Eradicate, as he helped
+Tom wheel the monoplane back into the shed.
+
+"Is that so, Rad? Where is he?"
+
+"Settin' in th' library. Yo' father am out, so I asted him in
+dere."
+
+"That's right, Rad. Who is he, do you know?"
+
+"No, sah, Massa Tom, I doan't. He shore does use a pow'ful nice
+perfume on his pocket hanky, though. Yum-yum!"
+
+"Perfume!" exclaimed Tom, his mind going back to the day he had
+had the trouble with Mr. Peters. "Is he a big, red-faced man,
+Rad?"
+
+"No, sah, Massa Tom. He's a white-faced, skinny man."
+
+"Then it can't be Peters," mused Tom. "I guess perhaps it's that
+lawyer I wrote to about bringing suit to get back what it cost me
+to have the Kilo fixed. I'll see him at once. Oh, by the way, it
+isn't Mr. Grant Halling; is it? The gentleman who got tangled up
+in our aerials with his airship? Is it he?"
+
+"No, sah, Massa Tom. 'Tain't him."
+
+"I thought perhaps he had gotten into more trouble," mused Tom, as
+he took off his airship "togs," and started for the house. For Mr.
+Halling had called for his repaired airship some time ago, and had
+promised to pay Tom another and more conventional visit, some
+future day.
+
+Tom did not know the visitor whom he greeted in the library a
+little later. The man, as Eradicate had said, was rather pale of
+face, and certainly he was not very fleshy.
+
+"Mr. Tom Swift, I think?" said the man, rising and holding out his
+hand.
+
+"That's my name. I don't believe I know you, though."
+
+"No, I haven't your reputation," said the man, with a laugh that
+Tom did not like. "We can't all be great inventors like you," and,
+somehow, Tom liked the man less than before, for he detected an
+undertone of sneering patronage in the words. Tom disliked praise,
+and he felt that this was not sincere.
+
+"I have called on a little matter of business," went on the man.
+"My name is Harrison Boylan, and I represent Mr. Shallock Peters."
+
+Instinctively Tom stiffened. Receiving a call from a
+representative of the man against whom Mr. Damon had warned him
+only a short time before was a strange coincidence, Tom thought.
+
+"You had some little accident, when your motor boat and that of
+Mr. Peters collided, a brief time ago; did you not?" went on Mr.
+Boylan.
+
+"I did," said Tom, and, as he motioned the caller to be seated Tom
+saw, with a start, that some of the drawings of his photo
+telephone were lying on a desk in plain sight. They were within
+easy reach of the man, and Tom thought the sheets looked as though
+they had been recently handled. They were not in the orderly array
+Tom had made of them before going out.
+
+"If he is a spy, and has been looking at them," mused Tom, "he may
+steal my invention." Then he calmed himself, as he realized that
+he, himself, had not yet perfected his latest idea. "I guess he
+couldn't make much of the drawings," Tom thought.
+
+"Yes, the collision was most unfortunate," went on Mr. Boylan,
+"and Mr. Peters has instructed me to say--"
+
+"If he's told you to say that it was my fault, you may as well
+save your time," cut in Tom. "I don't want to be impolite, but I
+have my own opinion of the affair. And I might add that I have
+instructed a lawyer to begin a suit against Mr. Peters--"
+
+"No necessity for that at all!" interrupted the man, in soft
+accents. "No necessity at all. I am sorry you did that, for there
+was no need. Mr. Peters has instructed me to say that he realizes
+the accident was entirely his own fault, and he is very willing--
+nay, anxious, to pay all damages. In fact, that is why I am here,
+and I am empowered, my dear Mr. Swift, to offer you five hundred
+dollars, to pay for the repairs to your motor boat. If that is not
+enough--"
+
+The man paused, and drew a thick wallet front his pocket. Tom felt
+a little embarrassed over what he had said.
+
+"Oh," spoke the young inventor, "the repair bill is only about
+three hundred dollars. I'm sorry--"
+
+"Now that's all right, Mr. Swift! It's all right," and the man,
+with his soft words, raised a white, restraining hand. "Not
+another word. Mr. Peters did not know who you were that day he so
+unfortunately ran into you. If he had, he would not have spoken as
+he did. He supposed you were some amateur motor-boatist, and he
+was--well, he admits it--he was provoked."
+
+"Since then he has made inquiries, and, learning who you were, he
+at once authorized me to make a settlement in full. So if five
+hundred dollars--"
+
+"The repair bill," said Tom, and his voice was not very cordial,
+in spite of the other's persuasive smile, "the bill came to three
+hundred forty-seven dollars. Here is the receipted bill. I paid
+it, and, to be frank with you, I intended bringing suit against
+Mr. Peters for that sum."
+
+"No need, no need at all, I assure you!" interrupted Mr. Boylan,
+as he counted off some bills. "There you are, and I regret that
+you and Mr. Peters had such a misunderstanding. It was all his
+fault, and he wants to apologize to you."
+
+"The apology is accepted," said Tom, and he smiled a trifle. "Also
+the money. I take it merely as a matter of justice, for I assure
+you that Mr. Peters's own machinist will say the accident was his
+employer's fault."
+
+"No doubt of it, not the least in the world," said the caller.
+"And now that I have this disagreeable business over, let me speak
+of something more pleasant."
+
+Instinctively Tom felt that now the real object of the man's call
+would be made plain--that the matter of paying the damages was
+only a blind. Tom steeled himself for what was to come.
+
+"You know, I suppose," went on Mr. Boylan, smiling at Tom, "that
+Mr. Peters is a man of many and large interests."
+
+"I have heard something like that," said Tom, cautiously.
+
+"Yes. Well, he is an organizer--a promoter, if you like. He
+supplies the money for large enterprises, and is, therefore, a
+benefactor of the human race. Where persons have no cash with
+which to exploit their--well, say their inventions. Mr. Peters
+takes them, and makes money out of them."
+
+"No doubt," thought Tom, grimly.
+
+"In other cases, where an inventor is working at a handicap, say
+with too many interests, Mr. Peters takes hold of one of his
+ideas, and makes it pay much better than the inventor has been
+able to do."
+
+"Now, Mr. Peters has heard of you, and he would like to do you
+good."
+
+"Yes, I guess he would," thought Tom. "He would like to do me--and
+do me good and brown. Here's where I've got to play a game
+myself."
+
+"And so," went on Mr. Boylan, "Mr. Peters has sent me to you to
+ask you to allow him to exploit one, or several, of your
+inventions. He will form a large stock company, put one of your
+inventions on the market, and make you a rich man. Now what do you
+say?" and he looked at Tom and smiled--smiled, the young inventor
+could not help thinking, like a cat looking at a mouse. "What do
+you say, Mr. Swift?"
+
+For a moment Tom did not answer. Then getting up and opening the
+library door, to indicate that the interview was at an end, the
+young inventor smiled, and said:
+
+"Tell Mr. Peters that I thank him, but that I have nothing for him
+to exploit, or with which to form a company to market."
+
+"Wha--what!" faltered the visitor. "Do you mean to say you will
+not take advantage of his remarkable offer?"
+
+"That's just what I mean to say," replied Tom, with a smile.
+
+"You won't do business with Mr. Peters? You won't let him do you
+good?"
+
+"No," said Tom, quietly.
+
+"Why--why, that's the strangest--the most preposterous thing I
+ever heard of!" protested Mr. Boylan. "What--what shall I say to
+Mr. Peters?"
+
+"Tell him," said Tom, "tell him, from me, and excuse the slang, if
+you like, but tell him there is--nothing doing!"
+
+
+
+
+
+CHAPTER VIII
+
+TOM IS BAFFLED
+
+
+Amazement held Mr. Boylan silent for a moment, and then, staring
+at Tom, as though he could not believe what he had heard the young
+inventor say, the representative of Mr. Peters exclaimed:
+
+"Nothing doing?"
+
+"That's what I said," repeated Tom, calmly.
+
+"But--but you don't understand, I'm afraid."
+
+"Oh, but indeed I do."
+
+"Then you refuse to let my friend, Mr. Peters, exploit some of
+your inventions?"
+
+"I refuse absolutely."
+
+"Oh, come now. Take an invention that hasn't been very
+successful."
+
+"Well, I don't like to boast," said Tom with a smile, "but all of
+my inventions have been successful. They don't need any aid from
+Mr. Peters, thank you."
+
+"But this one!" went on the visitor eagerly, "this one about some
+new kind of telephone," and he motioned to the drawings on the
+table. "Has that been a success? Excuse me for having looked at
+the plans, but I did not think you would mind. Has that telephone
+been a success? If it has not perhaps Mr. Peters could form a
+company to--"
+
+"How did you know those drawings referred to a telephone?" asked
+Tom, suspiciously, for the papers did not make it clear just what
+the invention was.
+
+"Why, I understood--I heard, in fact, that you were working on a
+new photo telephone, and--"
+
+"Who told you?" asked Tom quickly.
+
+"Oh, no one in particular. The colored man who sent me here
+mentioned--"
+
+"Eradicate!" thought Tom. "He must have been talking. That isn't
+like him. I must look into this."
+
+Then to his caller he said:
+
+"Really, you must excuse me, Mr. Boylan, but I don't care to do
+any business with Mr. Peters. Tell him, with my thanks, that there
+is really nothing doing in his line. I prefer to exploit my own
+inventions."
+
+"That is your last word?"
+
+"Yes," returned Tom, as he gathered up the drawings.
+
+"Well," said Mr. Boylan, and Tom could not help thinking there was
+a veiled threat in his tones, "you will regret this. You will be
+sorry for not having accepted this offer."
+
+"I think not," replied Tom, confidently. "Good-day."
+
+The young inventor sat for some time thinking deeply, when his
+visitor had gone. He called Eradicate to him, and gently
+questioned the old colored man, for Eradicate was ageing fast of
+late, and Tom did not want him to feel badly.
+
+It developed that the servant had been closely cross-questioned by
+Mr. Boylan, while he was waiting for Tom, and it was small wonder
+that the old colored man had let slip a reference to the photo
+telephone. But he really knew nothing of the details of the
+invention, so he could have given out no secrets.
+
+"But at the same time," mused Tom, "I must be on guard against
+these fellows. That Boylan seems a pretty slick sort of a chap. As
+for Peters, he's a big 'bluff,' to be perfectly frank. I'm glad I
+had Mr. Damon's warning in mind, or I might have been tempted to
+do business with him."
+
+"Now to get busy at this photo telephone again. I'm going to try a
+totally different system of transmission. I'll use an alternating
+current on the third wire, and see if that makes it any better.
+And I'll put in the most sensitive selenium plate I can make. I'm
+going to have this thing a success."
+
+Tom carefully examined the drawings of his invention, at which
+papers Mr. Boylan had confessed to looking. As far as the young
+inventor could tell none was missing, and as they were not
+completed it would be hard work for anyone not familiar with them
+to have gotten any of Tom's ideas.
+
+"But at the same time I'm going to be on my guard," mused Tom.
+"And now for another trial."
+
+Tom Swift worked hard during the following week, and so closely
+did he stick to his home and workshop that he did not even pay a
+visit to Mr. Damon, so he did not learn in what condition that
+gentleman's affairs were. Tom even denied himself to his chum Ned,
+so taken up was the young inventor with working out the telephone
+problem, until Ned fairly forced himself into the shop one day,
+and insisted on Tom coming out.
+
+"You need some fresh air!" exclaimed Ned. "Come on out in the
+motor boat again. She's all fixed now; isn't she?"
+
+"Yes," answered Tom, "but--"
+
+"Oh, 'but me no buts,' as Mr. Shakespeare would say. Come on, Tom.
+It will do you good. I want a spin myself."
+
+"All right, I will go for a little while," agreed Tom. "I am
+feeling a bit rusty, and my head seems filled with cobwebs."
+
+"Can't get the old thing to come out properly; eh?"
+
+"No. I guess dad was more than half right when he said it couldn't
+be done. But I haven't given up. Maybe I'll think of some new plan
+if I take a little run. Come along."
+
+They went down to the boat house, and soon were out on the lake in
+the Kilo.
+
+"She runs better since you had her fixed," remarked Ned.
+
+"Yes, they did a good job."
+
+"Did you sue Peters?"
+
+"Didn't have to. He sent the money," and Tom told of his interview
+with Mr. Boylan. This was news to Ned, as was also the financial
+trouble of Mr. Damon.
+
+"Well," said the young banker, "that bears out what I had heard of
+Peters--that he was a get-rich-quick chap, and a good one to steer
+clear of."
+
+"Speaking of steering clear," laughed Tom, "there he is now, in
+his big boat," and he pointed to a red blur coming up the lake.
+"I'll give him a wide enough berth this time."
+
+But though Mr. Peters, in his powerful motor boat, passed close to
+Tom's more modest craft, the big man did not glance toward our
+hero and his chum. Nor did Mr. Boylan, who was with his friend,
+look over.
+
+"I guess they've had enough of you," chuckled Ned.
+
+"Probably he wishes he hadn't paid me that money," said Tom. "Very
+likely he thought, after he handed it over, that I'd be only too
+willing to let him manage one of my inventions. But he has another
+guess coming."
+
+Tom and Ned rode on for some distance, thoroughly enjoying the
+spin on the lake that fine Summer day. They stopped for lunch at a
+picnic resort, and coming back in the cool of the evening they
+found themselves in the midst of a little flotilla of pleasure
+craft, all decorated with Japanese lanterns.
+
+"Better slow down a bit," Ned advised Tom, for many of the
+pleasure craft were canoes and light row boats. "Our wash may
+upset some of them."
+
+"Guess you're right, old man," agreed Tom, as he closed the
+gasoline throttle, to reduce speed. Hardly had he done so than
+there broke in upon the merry shouts and singing of the pleasure-
+seekers the staccato exhaust of a powerful motor boat, coming
+directly behind Tom's craft.
+
+Then came the shrill warning of an electrical siren horn.
+
+"Somebody's in a hurry," observed Tom.
+
+"Yes," answered Ned. "It sound's like Peters's boat, too."
+
+"It is!" exclaimed Tom. "Here he comes. He ought to know better
+than to cut through this raft of boats at that speed."
+
+"Is he headed toward us?"
+
+"No, I guess he's had enough of that. But look at him!"
+
+With undiminished speed the burly promoter was driving his boat
+on. The big vibrating horn kept up its clamor, and a powerful
+searchlight in front dazzled the eyes.
+
+"Look out! Look out!" cried several.
+
+Many of the rowers and paddlers made haste to clear a lane for the
+big, speedy motor craft, and Peters and his friends (for there
+were several men in his boat now) seemed to accept this as a
+matter of course, and their right.
+
+"Somebody'll be swamped!" exclaimed Ned.
+
+Hardly had he spoken than, as the big red boat dashed past in a
+smother of foam, there came a startled cry in girls' voices.
+
+"Look!" cried Tom. "That canoe's upset! Speed her up, Ned! We've
+got to get 'em!"
+
+
+
+
+
+CHAPTER IX
+
+A GLEAM OF HOPE
+
+
+"Where are they?"
+
+"Who are they?"
+
+"Over this way! There's their canoe!"
+
+"Look out for that motor boat!"
+
+"Who was it ran them down? They ought to be arrested!"
+
+These were only a few of the cries that followed the upsetting of
+the frail canoe by the wash from the powerful red boat. On Tom's
+Kilo there was a small, electrical searchlight which he had not
+yet switched on. But, with his call to Ned Newton to speed up the
+motor, that had been slowed down, Tom, with one turn of his
+fingers, set the lamp aglow, while, with the other hand, he
+whirled the wheel over to head his craft for the spot where he saw
+two figures struggling in the water.
+
+Fortunately the lanterns on the various canoes and row-boats, as
+well as the light on the bow of Tom's Kilo, made an illumination
+that gave the rescuers a good chance to work. Many other boats
+besides Tom's had headed for the scene, but his was the more
+practical, since the others--all quite small ones--were pretty
+well filled.
+
+"There they are, Ned!" Tom suddenly cried. "Throw out the clutch!
+I'll get 'em!"
+
+"Want any help?"
+
+"No, you stay at the engine, and mind what I say. Reverse now!
+We're going to pass them!"
+
+Ned threw in the backing gear, and the screw churned the water to
+foam under the stern of the Kilo.
+
+Tom leaned over the bow, and made a grab for the gasping,
+struggling figure of a girl in the water. At the same time he had
+tossed overboard a cork life ring, attached to a rope which, in
+turn, was made fast to the forward deck-cleat. "Grab that!" cried
+Tom. "Hold on, and I'll have you out in a second! That's enough,
+Ned! Shut her off!"
+
+The Kilo came to a standstill, and, a second later, Tom had pulled
+into his boat one of the girls. She would have collapsed, and
+fallen in a heap on the bottom boards, had not Ned, who had come
+forward from the engine, caught her.
+
+Then Tom, again leaning over the side, pulled in the other girl,
+who was clinging to the life ring.
+
+"You're all right," Tom assured her, as she came up, gasping,
+choking and crying hysterically. "You're all right!"
+
+"Is--is Minnie saved?" she sobbed.
+
+"Yes, Grace! I'm here," answered the one Ned was supporting.
+
+"Oh, wasn't it terrible!" cried the second girl Tom had saved.
+
+"I thought we would be drowned, even though we can swim."
+
+"Yes, it--it was so--so sudden!" gasped her companion. "What
+happened?"
+
+"The wash from that big boat upset you," explained Tom. "That
+fellow ought to be ashamed of himself, rushing along the way he
+did. Now, can I take you girls anywhere? Your canoe seems to have
+drifted off."
+
+"I have it!" someone called. "It's turned over, but I can tow it
+to shore."
+
+"And I'll take the girls home," offered a gentleman in a large
+rowboat. "My wife will look after them. They live near us," and he
+mentioned his own name and the names of the two girls Tom had
+saved. The young inventor did not know them, but he introduced
+himself and Ned.
+
+"This is the annual moonlight outing of our little boat club,"
+explained the man who had offered to look after the girls, "and it
+is the first time we ever had an accident. This was not our fault,
+though."
+
+"Indeed it was not," agreed Tom, after he had helped the two
+dripping young ladies into the rowboat. "It was due to Mr.
+Peters's speed mania."
+
+"I shall make a complaint against him to the navigation
+authorities," said Mr. Ralston, who was looking after the girls.
+"He must think he, alone, has any rights on this lake."
+
+With renewed thanks to Tom and Ned, the rescued girls were rowed
+off to their homes, while the interrupted water carnival was
+continued.
+
+"Some little excitement; eh, Tom?" remarked Ned, when they were
+once more under way.
+
+"Yes. We seem to run into that fellow Peters, or some of his
+doings, quite often lately."
+
+"And it isn't a good sign, either," murmured Ned.
+
+For some minutes after that Tom did not speak. In fact he was so
+silent that Ned at last inquired:
+
+"What's the matter, Tom--in love?"
+
+"Far from it. But, Ned, I've got an idea."
+
+"And I've got a wet suit of clothes where that nice young lady
+fainted in my arms. I'm soaked."
+
+"That's what gave me the idea--the water, I mean. I noticed how
+everything was reflected in it, and, do you know, Ned, I believe I
+have been working on the wrong principle for my photo telephone."
+
+"Wrong, Tom, how is that?"
+
+"Why, I've been using a dry plate, and I think I should have used
+a wet one. You know how even in a little puddle of water on the
+sidewalk you can see yourself reflected?"
+
+"Yes, I've often seen that."
+
+"Well then, 'bless my watch chain!' as Mr. Damon would say, I
+think I've got just what I want. I'm going to try a wet plate now,
+and I think it will work. Come on now. Speed up! I'm in a great
+big hurry to get home and try it!"
+
+"Well, Tom, I sure will be glad if you've got the right idea,"
+laughed Ned. "It will be worth getting wet through for, if you
+strike something. Good luck!"
+
+Tom could hardly wait to fasten up his boat for the night, so
+eager was he to get to his shop laboratory and try the new idea. A
+gleam of hope had come to him.
+
+It was still early evening, and Tom, when enticed out by Ned, had
+left his photo telephone apparatus in readiness to go on with his
+trials as soon as he should have come back.
+
+"Now for it, Ned!" exclaimed the young inventor, as he took off
+his coat. "First I'll sensitize a selenium plate, and then I'll
+wet it. Water is always a good conductor of electricity, and it's
+a wonder that I forgot that when I was planning this photo
+telephone. But seeing the sparkle of lights, and the reflection of
+ourselves in the lake to-night, brought it back to me. Now then,
+you haven't anything special to do; have you?"
+
+"Not a thing, Tom."
+
+"That's good. Then you get in this other telephone closet--the one
+in the casting shop. I'll put a prepared plate in there, and one
+in the booth where I'm to sit. Then I'll switch on the current,
+and we'll see if I can make you out, and you notice whether my
+image appears on your plate."
+
+It took some little time to make ready for this new test. Tom was
+filled with enthusiasm, and he was sure it was going to be
+successful this time. Ned watched him prepare the selenium plates
+--plates that were so sensitive to illumination that, in the dark,
+the metal would hardly transmit a current of electricity, but in
+the light would do so readily, its conductivity depending on the
+amount of light it received.
+
+"There, I guess we're all ready, Ned," announced Tom, at last.
+"Now you go to your little coop, and I'll shut myself up in mine.
+We can talk over the telephone."
+
+Seated in the little booth in one of the smaller of Tom's shops,
+Ned proceeded with his part in the new experiment. A small shelf
+had been fitted up in the booth, or closet, and on this was the
+apparatus, consisting of a portable telephone set, and a small
+box, in which was set a selenium plate. This plate had been wet by
+a spray of water in order to test Tom's new theory.
+
+In a similar booth, several hundred feet away, and in another
+building, Tom took his place. The two booths were connected by
+wires, and in each one was an electric light.
+
+"All ready, Ned?" asked Tom, through the telephone.
+
+"All ready," came the answer.
+
+"Now then, turn on your switch--the one I showed you--and look
+right at the sensitized plate. Then turn out your light, and
+slowly turn it on. It's a new kind, and the light comes up
+gradually, like gas or an oil lamp. Turn it on easily."
+
+"I get you, Tom."
+
+Ned did as requested. Slowly the illumination in the booth
+increased.
+
+"Do you get anything, Tom?" asked Ned, over the wire.
+
+"Not yet," was the somewhat discouraged answer. "Go ahead, turn on
+more light, and keep your face close to the plate."
+
+Ned did so.
+
+"How about it now?" he asked, a moment later.
+
+"Nothing--yet," was the answer. And then suddenly Tom's voice rose
+to a scream over the wire.
+
+"Ned--Ned! Quick!" he called. "Come here--I--I--"
+
+The voice died off into a meaningless gurgle.
+
+
+
+
+
+CHAPTER X
+
+MIDNIGHT VISITORS
+
+
+Ned Newton never knew exactly how he got out of the telephone
+booth. He seemed to give but one jump, tearing the clamped
+receiver from his ear, and almost upsetting the photo apparatus in
+his mad rush to help Tom. Certain it is, however, that he did get
+out, and a few seconds later he was speeding toward the shop where
+Tom had taken his position in a booth.
+
+Ned burst in, crying out:
+
+"Tom! What is it? What happened? What's the matter?"
+
+There was no answer. Fearing the worst, Ned hurried to the small
+booth, in one corner of the big, dimly lighted shop. He could see
+Tom's lamp burning in the telephone compartment,
+
+"Tom! Tom!" called the young banker.
+
+Still there was no answer, and Ned, springing forward, threw open
+the double, sound-proof door of the booth. Then he saw Tom lying
+unconscious, with his head and arms on the table in front of him,
+while the low buzzing of the electrical apparatus in the
+transmitting box told that the current had not been shut off.
+
+"Tom! Tom!" cried Ned in his chum's ear He shook him by the
+shoulder,
+
+"Are you hurt? What is the matter?"
+
+The young inventor seemed unconscious, and for a moment Ned had a
+wild idea that Tom had been shocked to death, possibly by some
+crossed live wire coming in contact with the telephone circuit.
+
+"But that couldn't have happened, or I'd have been shocked
+myself," mused Ned.
+
+Then he became aware of a curious, sweet, sickish odor in the
+booth. It was overpowering. Ned felt himself growing dizzy.
+
+"I have it--chloroform!" he gasped. "In some way Tom has been
+overcome by chloroform. I've got to get him to the fresh air."
+
+Once he had solved the puzzle of Tom's unconsciousness, Ned was
+quick to act. He caught Tom under the arms, and dragged him out of
+the booth, and to the outer door of the shop. Almost before Ned
+had reached there with his limp burden, Tom began to revive, and
+soon the fresh, cool night air completed the work.
+
+"I--I," began the young inventor. "Ned, I--I--"
+
+"Now take it easy, Tom," advised his chum. "You'll be all right in
+a few minutes. What happened? Shall I call your father, or Koku?"
+
+"No--don't. It would only--only alarm dad," faltered Tom. "I'm
+getting all right now. But he--he nearly had me, Ned!"
+
+"He had you? What do you mean, Tom? Who had you?"
+
+"I don't know who it was, but when I was talking to you over the
+wire, all of a sudden I felt a hand behind me. It slipped over my
+mouth and nose, and I smelled chloroform. I knew right away
+something was wrong, and I called to you. That's all I remember. I
+guess I must have gone off."
+
+"You did," spoke Ned. "You were unconscious when I got to you. I
+couldn't imagine what had happened. First I thought it was an
+electrical shock. Then I smelled that chloroform. But who could it
+have been, Tom?"
+
+"Give it up, Ned! I haven't the slightest idea."
+
+"Could they have been going to rob you?"
+
+"I haven't a thing but a nickel watch on me," went on Tom. "I left
+all my cash in the house. If it was robbery, it wasn't me,
+personally, they were after."
+
+"What then? Some of your inventions?"
+
+"That's my idea now, Ned. You remember some years ago Jake Burke
+and his gang held me up and took one of dad's patents away from
+me?"
+
+"Yes, I've heard you mention that. It was when you first got your
+motor cycle; wasn't it?"
+
+"That's right. Well, what I was going to say was that they used
+chloroform on me then, and--"
+
+"You think this is the same crowd? Why, I thought they were
+captured."
+
+"No, they got away, but I haven't heard anything of them in years.
+Now it may be they have come back for revenge, for you know we got
+back the stolen property."
+
+"That's right. Say, Tom, it might be so. What are you going to do
+about it?"
+
+"I hardly know. If it was Jake Burke, alias Happy Harry, and his
+crowd, including Appleson, Morse and Featherton, they're a bad
+lot. I wouldn't want father to know they were around, for he'd be
+sure to worry himself sick. He never really got over the time they
+attacked me, and got the patent away. Dad sure thought he was
+ruined then."
+
+"Now if I tell him I was chloroformed again to-night, and that I
+think it was Burke and his crowd, he'd be sure to get ill over it.
+So I'm just going to keep mum."
+
+"Well, perhaps it's the best plan. But you ought to do something."
+
+"Oh, I will, Ned, don't worry about that. I feel much better now."
+
+"How did it happen?" asked Ned, his curiosity not yet satisfied.
+
+"I don't know, exactly. I was in the booth, talking to you, and
+not paying much attention to anything else. I was adjusting and
+readjusting the current, trying to get that image to appear on the
+plate. All at once, I felt someone back of me, and, before I could
+turn, that hand, with the chloroform sponge, was over my mouth and
+nose. I struggled, and called out, but it wasn't much use."
+
+"But they didn't do anything else--they didn't take anything; did
+they, Tom?"
+
+"I don't know, Ned. We'll have to look around. They must have
+sneaked into the shop. I left the door open, you see. It would
+have been easy enough."
+
+"How many were there?"
+
+"I couldn't tell. I only felt one fellow at me; but he may have
+had others with him."
+
+"What particular invention were they after, Tom?"
+
+"I'm sure I don't know. There are several models in here that
+would be valuable. I know one thing, though, they couldn't have
+been after my photo telephone," and Tom laughed grimly.
+
+"Why not?" Ned wanted to know.
+
+"Because it's a failure--that's what! It's a dead, sure failure,
+Ned, and I'm going to give it up!" and Tom spoke bitterly.
+
+"Oh, don't say that!" urged his chum. "You may be right on the
+verge of perfecting it, Tom. Didn't you see any image at all on
+the plate?"
+
+"Not a shadow. I must be on the wrong track. Well, never mind
+about that now. I'm going to look around, and see if those fellows
+took anything."
+
+Tom was feeling more like himself again, the effects of the
+chloroform having passed away. He had breathed the fumes of it for
+only a little while, so no harm had been done. He and Ned made an
+examination of the shop, but found nothing missing.
+
+There were no traces of the intruders, however, though the two
+chums looked carefully about outside the building.
+
+"You were too quick for them, Ned," said Tom. "You came as soon as
+I called. They heard me speaking, and must have known that I had
+given the alarm."
+
+"Yes, I didn't lose any time," admitted Ned, "but I didn't see a
+sign of anyone as I ran up."
+
+"They must have been pretty quick at getting away. Well, now to
+decide what's best to do to-night."
+
+After some consultation and consideration it was decided to set
+the burglar alarms in every building of the Swift plant. Some time
+previous, when he had been working on a number of valuable
+inventions, unscrupulous men had tried to steal his ideas and
+models. To prevent this Tom had arranged a system of burglar
+alarms, and had also fitted up a wizard camera that would take
+moving pictures of anyone coming within its focus. The camera
+could be set to work at night, in connection with the burglar
+alarms.
+
+The apparatus was effective, and thus an end was put to the
+efforts of the criminals. But now it seemed Tom would have to take
+new precautionary measures. His camera, however, was not
+available, as he had loaned it to a scientific society for
+exhibition.
+
+"But we'll attach the burglar wires," decided Tom, "and see what
+happens."
+
+"It might be a good plan to have Koku on guard," said Tom's chum.
+"That giant could handle four or five of the chaps as easily as
+you and I could tackle one."
+
+"That's right," agreed Tom. "I'll put him on guard. Whew! That
+chloroform is giving me a headache. Guess I'll go to bed. I wish
+you'd stay over to-night, Ned, if you haven't anything else to do.
+I may need you."
+
+"Then of course I'll stay, Tom. I'll telephone home that I won't
+be in."
+
+A little later Tom had put away his new photo telephone apparatus,
+and had prepared for the warm reception of any unbidden callers.
+
+"I wish I hadn't started on this new invention," said Tom, half
+bitterly, as he locked up the main parts of his machine, "I know
+it will never work."
+
+"Oh, yes it will," spoke Ned, cheerfully. "You never failed yet,
+Tom Swift, in anything you undertook, and you're not going to
+now."
+
+"Well, that's good of you to say, Ned, but I think you're wrong
+this time. But I'm not going to think any more about it to-night,
+anyhow. Now to find Koku and put him on watch."
+
+The giant listened carefully to Tom's simple instructions.
+
+"If any bad men come in the night, Koku," said the young inventor,
+"you catch them!"
+
+"Yes, master, me catch!" said Koku, grimly. "Me catch!" and he
+stretched out his powerful arms, and clenched his big hands in a
+way that boded no good to evildoers.
+
+Nothing was said to Mr. Swift, to Mrs. Baggert, or to Eradicate
+about what had happened, for Tom did not want to worry them. The
+burglar alarms were set, Koku took his place where he could watch
+the signals, and at the same time be ready to rush out, for,
+somehow, Tom had an idea that the men who had attacked him would
+come back.
+
+Tom and Ned occupied adjoining rooms, and soon were ready for bed.
+But, somehow, Tom could not sleep. He lay awake, tossing from side
+to side, and, in spite of his resolution not to think about his
+photo telephone invention, his mind ran on nothing but that.
+
+"I can't see what next to do to make it work," he told himself,
+over and over again. "Something is wrong--but what?"
+
+At length he fell into a fitful doze, and he had a wild dream that
+he was sliding down hill on a big mirror in which all sorts of
+reflections were seen--reflections that he could not get to show
+in the selenium plates.
+
+Then Tom felt the mirror bobbing up and down like a motor boat in
+a storm. He felt the vibration, and he heard a voice calling in
+his ear:
+
+"Get up, Tom! Get up!"
+
+"Yes! What is it?" he sleepily exclaimed,
+
+"Hush!" was the caution he heard, and then he realized that his
+dream had been caused by Ned shaking him.
+
+"Well?" whispered Tom, in tense tones.
+
+"Midnight visitors!" answered his chum "The burglar alarm has just
+gone off! The airship hangar drop fell. Koku has gone out. Come
+on!"
+
+
+
+
+
+CHAPTER XI
+
+THE AIRSHIP IS TAKEN
+
+
+Tom leaped silently out of bed, and stood for a moment half
+dazed, so soundly had he been sleeping.
+
+"Come on!" urged Ned softly, realizing that his chum had not fully
+comprehended. "Koku will hold them until we get there. I haven't
+roused anyone else."
+
+"That's right," whispered Tom, as he began putting on his clothes.
+"I don't want father to know. When did it happen?"
+
+"Just a little while ago. I couldn't sleep very well, but I fell
+into a doze, and then I heard the buzzer of the alarm go off. I
+saw that the drop, showing that the hangar had been entered, had
+fallen. I got to the window in time to see Koku going toward the
+shed from his little coop. Then I came to you."
+
+"Glad you did," answered Tom. "I didn't think I was sleeping so
+soundly."
+
+Together the two chums made their way from their rooms down the
+dimly-lighted hall to a side door, whence they could reach the
+airship hangar, or shed.
+
+"Won't we need something--a gun or--" began Ned.
+
+"Clubs are better--especially at night when you can't see to aim
+very well," whispered back Tom. "I've got a couple of good ones
+downstairs. I could use my electric rifle, and set it merely to
+disable temporarily whoever the charge hit, but it's a little too
+risky. Koku has a habit of getting in the way at the most
+unexpected times. He's so big, you know. I think clubs will be
+best."
+
+"All right, Tom, just as you say," agreed Ned. "But who do you
+think it can be?"
+
+"I haven't the least idea. Probably the same fellows who were
+after me before, though. This time I'll find out what their game
+is, and what they're after."
+
+The chums reached the lower hall, and there Tom picked out two
+African war clubs which he had brought back with him from one of
+his many trips into wild lands.
+
+"These are just the thing!" exclaimed Ned, swinging his about.
+
+"Careful," cautioned Tom, "If you hit something you'll rouse the
+house, and I don't want my father and Mrs. Baggert, to say nothing
+of Eradicate, awakened."
+
+"Excuse me," murmured Ned. "But we'd better be getting a move on."
+
+"That's right," agreed Tom. He dropped into a side pocket a small
+but powerful electric flash lamp, and then he and Ned let
+themselves out.
+
+There had been a bright moon, but it was now overcast by clouds.
+However, there was sufficient light to enable the two lads to see
+objects quite clearly. All about them were the various buildings
+that made up the manufacturing and experimental plant of Tom Swift
+and his father. Farthest away from the house was the big shed
+where once Tom had kept a balloon, but which was now given over to
+his several airships. In front of it was a big, level grassy
+space, needed to enable the aircraft to get a "running start"
+before they could mount into the clouds.
+
+"See anything of Koku?" whispered Ned.
+
+"No," answered Tom, in the same cautious voice. "I guess he must
+be hiding--"
+
+"There he goes now!" hissed Ned, pointing to a big figure that was
+approaching the hangar. It was undoubtedly that of the giant, and
+he could be seen, in the dim light, stalking cautiously along.
+
+"I wonder where the uninvited guests are?" asked Tom.
+
+"Probably in the airship shed," answered Ned. "Koku was after them
+as soon as the alarm went off, and they couldn't have gotten away.
+They must be inside there yet. But what can their game be?"
+
+"It's hard to say," admitted Tom. "They may be trying to get
+something belonging to me, or they may imagine they can pick up
+some valuable secrets. Or they may--" He stopped suddenly, and
+then exclaimed:
+
+"Come on, Ned! They're after one of the airships! That's it! My
+big biplane is all ready to start, and they can get it in motion
+inside of a few seconds. Oh, why didn't I hurry?" he added,
+bitterly.
+
+But the hangar was still some distance away, and it would take two
+or three minutes of running to reach it.
+
+Meanwhile, and at the instant Tom had his thought of the possible
+theft of his biggest aircraft, something happened.
+
+The doors of the shed were suddenly thrown open, and the two boys
+could see the large airship being wheeled out. The hazy light of
+the moon behind the clouds shone on the expanse of white planes,
+and on the fish-tail rudder, one of Tom's latest ideas.
+
+"Hey, there!" cried Tom, warningly.
+
+"Leave that alone!" yelled Ned.
+
+"Koku! Koku!" shouted Tom, shrilly. "Get after those fellows!"
+
+"Me get!" boomed out the giant, in his deep voice.
+
+He had been standing near the entrance to the hangar, probably
+waiting for developments, and watching for the arrival of Tom and
+Ned. The big form was seen to leap forward, and then several dark
+shadows swarmed from around the airship, and were seen to fling
+themselves upon the giant.
+
+"That's a fight!" cried Ned. "They're attacking him!"
+
+"Koku can take care of himself!" murmured Tom. "But come on. I
+don't see what their game is."
+
+He understood a moment later, however, for while several of the
+midnight visitors were engaged in a hand-to-hand tussle with the
+giant there came a sharp, throbbing roar of the airship motor in
+motion. The propellers were being whirled rapidly about.
+
+"Koku! Koku!" cried Tom, for he was still some distance off.
+"Never mind them! Don't let the airship be taken!"
+
+But Koku could only grunt. Big and strong as he was, half a dozen
+men attacking him at once hampered him. He threw them from him,
+one after another, and was gradually making his way toward the now
+slowly-moving airship. But would he be in time?
+
+Tom and Ned could not hope to reach the machine before Koku,
+though they were running at top speed.
+
+"Koku! Koku!" yelled Tom. "Don't let them get away!"
+
+But Koku could only grunt--harder this time--for he fell heavily,
+being tripped by a stick thrust between his legs. He lay for a
+moment stunned.
+
+"They're going to get away!" panted Tom, making an effort to
+increase his speed.
+
+"That's what!" agreed Ned.
+
+Even as they spoke the roar of the airship motor increased.
+Several of the dark forms which had been engaged in the struggle
+with Koku were seen to pick themselves up, and run toward the
+airship, that was now in motion, moving on the bicycle wheels over
+the grass plot, preparatory to mounting upward in the sky.
+
+"Stop! Stop!" commanded Tom. But it was all in vain.
+
+The men leaped aboard the airship, which could carry six persons,
+and a moment later, with a deafening roar, as the engine opened up
+full, the big craft shot upward, taking away all but two of the
+midnight visitors. These, who had seemingly been stunned by Koku,
+now arose from the ground, and staggered off in the darkness.
+
+"Get them!" cried Tom.
+
+"We must see to Koku!" added Ned, "Look, there goes your airship,
+Tom!"
+
+"Yes, I know. But we can't stop that now. Let's see if we can get
+a clue in these fellows!"
+
+He pointed toward the two who had run off in the dark underbrush
+surrounding the hangar plaza, and he and Ned trailed them as well
+as they could. But from the first they knew it would be useless,
+for there were many hiding places, and, a little way beyond, was a
+clump of trees.
+
+After a short search Tom gave up reluctantly, and came back to
+where Koku was now sitting on the ground.
+
+"Are you hurt?" he asked of the giant.
+
+"My mind hurt--that all," said the big man.
+
+"I guess he means his feelings are hurt," Tom explained. "Do you
+know who they were, Koku?"
+
+"No, master."
+
+"But we must do something!" cried Ned. "They've got your airship,
+Tom."
+
+"I know it," said the young inventor, calmly. "But we can't do
+anything now. You can hardly hear her, let alone see her. She's
+moving fast!"
+
+He pointed upward to the darkness. Like some black bird of prey
+the airship was already lost to sight, though it would have seemed
+as if her white planes might render her visible. But she had moved
+so swiftly that, during the short search, she had already
+disappeared.
+
+"Aren't you going to do anything?" asked Ned.
+
+"Certainly," spoke Tom. "I'm going to telephone an alarm to all
+the nearby towns. This is certainly a queer game, Ned."
+
+
+
+
+
+CHAPTER XII
+
+A STRANGE DISAPPEARANCE
+
+
+Disappointed and puzzled, Tom and Ned went to where Koku was
+standing in rather a dazed attitude. The giant, like all large
+bodies, moved slowly, not only bodily but mentally. He could
+understand exactly what had happened, except that he had not
+prevailed over the "pygmies" who had attacked him. They had been
+too many for him.
+
+"Let's take a look inside," suggested Tom, when, by another glance
+upward, he had made sure that all trace of his big airship was
+gone. "Maybe we can get a clue. Then, Koku, you tell us what
+happened."
+
+"It all happened to me," said the giant, simply. "Me no make
+anything happen to them."
+
+"That's about right," laughed Tom, ruefully. "It all happened to
+us."
+
+The lights in the hangar were switched on, but a careful search
+revealed little. The men, half a dozen or more, had come evidently
+well prepared for the taking away of Tom Swift's airship, and they
+had done so.
+
+Entrance had been effected by forcing a small side door. True, the
+burglar alarm had given notice of the presence of the men, but Tom
+and Ned had not acted quite quickly enough. Koku had been at the
+hangar almost as soon as the men themselves, but he had watched
+and waited for orders, instead of going in at once, and this had
+given the intruders time to wheel out the craft and start the
+motor.
+
+"Why didn't you jump right in on them when you saw what they were
+up to, Koku?" asked Tom.
+
+"Me wait for master. Me think master want to see who men were. Me
+go in--they run."
+
+"Well, of course that's so, in a way," admitted Tom. "They
+probably would have run, but they'd have run WITHOUT my airship
+instead of WITH it, if they hadn't had time to get it outside the
+hangar. However, there's no use in crying over lost biplanes. The
+next thing is how to get her back. Did you know any of the men,
+Koku?"
+
+"No, master."
+
+"Then we haven't any clue that way. They laid their plans well.
+They just let you tangle yourself up with them, Koku, while the
+head ones got the motor going; an easy matter, since it was all
+ready to start. Then they tripped you, Koku, and as many of them
+as could, made a jump for the machine. Then they were off."
+
+"Well, what's the next thing to do?" asked Ned, when another look
+about the shed had shown that not the slightest clue was
+available.
+
+"I'm going to do some telephoning," Tom stated. "A big airship
+like mine can't go scooting around the country without being
+noticed. And those fellows can't go on forever. They've got to
+have gasoline and oil, and to get them they'll have to come down.
+I'll get it back, sooner or later; but the question is: Why did
+they take her?"
+
+"To sell," suggested Ned.
+
+"I think not," Tom said. "A big airship like mine isn't easy to
+sell. People who would buy it would ask questions that might not
+easily be answered. I'm inclined to think that some other reason
+made them take her, and it's up to us to find out what it was.
+Let's go into the house."
+
+"Hark!" suddenly exclaimed Ned, holding up his hand for silence.
+They all heard footsteps outside the hangar.
+
+Tom sprang to the door, flashing his electric light, and a voice
+exclaimed:
+
+"Golly! Chicken thieves!"
+
+"Oh, is it you, Eradicate?" asked the young inventor, with a
+laugh. "No, it isn't chicken thieves--they were after bigger game
+this time."
+
+"Suffin happen?" asked the colored man. "Massa Swift he heah a
+noise, an' see a light, an' he sent me out yeah t' see what all am
+gwine on."
+
+"Yes, something happened," admitted Tom. "They got the Eagle,
+Rad."
+
+"What! Yo' big airship?"
+
+"Yes."
+
+"Huh! Dat's too bad, Massa Tom. I suah am sorry t' heah dat. Who
+done it?"
+
+"We don't know, Rad."
+
+"Maybe it was dat low-down cousin ob mine what tried t' git mah
+chickens, onct!"
+
+"No, Rad, it wasn't your cousin. But I'll telephone the alarm to
+the police. They may be able to help me get the Eagle back."
+
+Within the next hour several messages were sent to the authorities
+of nearby towns, asking them to be on the watch for the stolen
+airship. This was about all that could be done, and after Mr.
+Swift had been told the story of the night's happenings, everyone
+went back to bed again.
+
+Further search the next morning brought forth no clues, though
+Tom, Ned and the others beat about in the bushes where the men had
+disappeared.
+
+One or two reports were heard from surrounding towns, to the
+effect that several persons had heard a strange throbbing sound in
+the night, that, possibly, was caused by the passage of the
+airship overhead. One such report came from Waterford, the home
+town of Mr. Damon.
+
+"Let's go over there," suggested Ned, to his chum. "I'd like to
+see our friend, and maybe we can get some other clues by
+circulating around there."
+
+"Oh, I don't know," spoke Tom, rather listlessly.
+
+"Why not?" Ned wanted to know.
+
+"Well, I ought to be working on my photo telephone," was the
+answer. "I've got a new idea now. I'm going to try a different
+kind of current, and use a more sensitive plate. And I'll use a
+tungsten filament lamp in the sending booth."
+
+"Oh, let your experiments go for a little while, Tom," suggested
+Ned. "Come on over to Mr. Damon's. The trouble with you is that
+you keep too long at a thing, once you start."
+
+"That's the only way to succeed," remarked Tom. "Really, Ned,
+while I feel sorry about the airship, of course, I ought to be
+working on my telephone. I'll get the Eagle back sooner or later."
+
+"That's not the way to talk, Tom. Let's follow up this clue."
+
+"Well, if you insist on it I suppose I may as well go. We'll take
+the little monoplane. I've fixed her up to carry double. I guess--
+"
+
+Tom Swift broke off suddenly, as the telephone at his elbow rang.
+
+"Hello," he said, taking off the receiver. "Yes, this is Tom
+Swift. Oh, good morning, Mrs. Damon! Eh! What's that? Mr. Damon
+has disappeared? You don't tell me! Disappeared! Yes, yes, I can
+come right over. Be there in a few minutes. Eh? You don't know
+what to make of it? Oh, well, maybe it can easily be explained.
+Yes, Ned Newton and I will be right over. Don't worry."
+
+Tom hung up the receiver and turned to his chum.
+
+"What do you think of that?" he asked.
+
+"What is it?"
+
+"Why, Mr. Damon mysteriously vanished last night, and this morning
+word came from his bankers that every cent of his fortune had
+disappeared! He's lost everything!"
+
+"Maybe--maybe--" hesitated Ned.
+
+"No, Mr. Damon isn't that kind of a man," said Tom, stoutly. "He
+hasn't made away with himself."
+
+"But something is wrong!"
+
+"Evidently, and it's up to us to find out what it is. I shouldn't
+be surprised but that he knew of this coming trouble and started
+out to prevent it if he could."
+
+"But he wouldn't disappear and make his wife worry."
+
+"No, that's so. Well, we'll have to go over there and find out all
+about it."
+
+"Say, Tom!" exclaimed Ned, as they were getting the small, but
+swift monoplane ready for the flight, "could there be any
+connection with the disappearance of Mr. Damon and the taking of
+the Eagle?"
+
+Tom started in surprise.
+
+"How could there be?" he asked.
+
+"Oh, I don't know," answered Ned. "It was only an idea."
+
+"Well, we'll see what Mrs. Damon has to say," spoke the young
+inventor, as he took his seat beside Ned, and motioned to Koku to
+twirl the propeller.
+
+
+
+
+
+CHAPTER XIII
+
+THE TELEPHONE PICTURE
+
+
+"Oh, Tom Swift! I'm so glad to see you!"
+
+Mrs. Damon clasped her arms, in motherly fashion, about the young
+inventor. He held her close, and his own eyes were not free from
+tears as he witnessed the grief of his best friend's wife.
+
+"Now, don't worry, Mrs. Damon," said Tom, sympathetically.
+"Everything will be all right," and he led her to a chair.
+
+"All right, Tom! How can it be?" and the lady raised a tear-
+stained face. "My husband has disappeared, without a word! It's
+just as if the earth had opened and swallowed him up! I can't find
+a trace of him! How can it be all right?"
+
+"Well, we'll find him, Mrs. Damon. Don't worry. Ned and I will get
+right to work, and I'll have all the police and detectives within
+fifty miles on the search--if we have to go that far."
+
+"Oh, it's awfully good of you, Tom. I--I didn't know who else to
+turn to in my trouble but you."
+
+"And why shouldn't you come to me? I'd do anything for you and Mr.
+Damon. Now tell me all about it."
+
+Tom and Ned had just arrived at the Damon home in the airship, to
+find the wife of the eccentric man almost distracted over her
+husband's strange disappearance.
+
+"It happened last night," Mrs. Damon said, when she was somewhat
+composed. "Last night about twelve o'clock."
+
+"Twelve o'clock!" cried Tom, in surprise "Why that's about the
+time--"
+
+He stopped suddenly.
+
+"What were you going to say?" asked Mrs. Damon.
+
+"Oh--nothing," answered Tom. "I--I'll tell you later. Go on,
+please."
+
+"It is all so confusing," proceeded Mrs. Damon. "You know my
+husband has been in trouble of late--financial trouble?"
+
+"Yes," responded Tom, "he mentioned it to me."
+
+"I don't know any of the details," sighed Mrs. Damon, "but I know
+he was mixed up with a man named Peters."
+
+"I know him, too," spoke Tom, grimly.
+
+"My husband has been very gloomy of late," went on Mrs. Damon. "He
+foolishly entrusted almost his entire fortune to that man, and
+last night he told me it was probably all gone. He said he saw
+only the barest chance to save it, but that he was going to take
+that chance."
+
+"Did he go into details?" asked Tom.
+
+"No, that was all he said. That was about ten o'clock. He didn't
+want to go to bed. He just sat about, and he kept saying over and
+over again: 'Bless my tombstone!' 'Bless the cemetery!' and all
+such stuff as that. You know how he was," and she smiled through
+her tears.
+
+"Yes," said Tom. "I know. Only it wasn't like him to bless such
+grewsome things. He was more jolly."
+
+"He hasn't been, of late," sighed his wife. "Well, he sat about
+all the evening, and he kept figuring away, trying, I suppose, to
+find some way out of his trouble."
+
+"Why didn't he come to my father?" cried Tom. "I told him he could
+have all the money he needed to tide him over."
+
+"Well, Mr. Damon was queer that way," said his wife. "He wanted to
+be independent. I urged him to call you up, but he said he'd fight
+it out alone."
+
+"As I said, we sat there, and he kept feeling more and more blue,
+and blessing his funeral, and the hearse and all such things as
+that. He kept looking at the clock, too, and I wondered at that."
+
+"'Are you expecting someone?' I asked him. He said he wasn't,
+exactly, but I made sure he was, and finally, about half-past
+eleven, he put on his hat and went out."
+
+"'Where are you going?' I asked him."
+
+"'Oh, just to get a breath of air. I can't sleep,' he said. I
+didn't think much of that, as he often used to go out and walk
+about a bit before going to bed. So he went out, and I began to
+see about locking up, for I never trust the servants."
+
+"It must have been about an hour later when I heard voices out in
+front. I looked, and I saw Mr. Damon talking to a man."
+
+"Who was he?" asked Tom, eagerly, on the alert for the slightest
+clue.
+
+"I thought at the time," said Mrs. Damon, "that it was one of the
+neighbors. I have learned since, however, that it was not. Anyhow,
+this man and Mr. Damon stood talking for a little while, and then
+they went off together. I didn't think it strange at the time,
+supposing he was merely strolling up and down in front with Mr.
+Blackson, who lives next door, He often had done that before."
+
+"Well, I saw that the house was locked up, and then I sat down in
+a chair to wait for Mr. Damon to come back. I was getting sleepy,
+for we don't usually stay up so late. I suppose I must have dozed
+off, but I was suddenly awakened by hearing a peculiar noise. I
+sat up in alarm, and then I realized that Mr. Damon had not come
+in."
+
+"I was frightened then, and I called my maid. It was nearly one
+o'clock, and my husband never stays out as late as that. We went
+next door, and found that Mr. Blackson had not been out of his
+house that evening. So it could not have been he to whom Mr. Damon
+was speaking."
+
+"We roused up other neighbors, and they searched all about the
+grounds, thinking he might have been overcome by a sudden faint.
+But we could not find him. My husband had disappeared--
+mysteriously disappeared!" and the lady broke into sobs.
+
+"Now don't worry," said Tom, soothingly, as he put his arms about
+her as he would have done to his own mother, had she been alive,
+"We'll get him back!"
+
+"But how can you? No one knows where he is."
+
+"Oh, yes!" said Tom, confidently, "Mr. Damon himself knows where
+he is, and unless he has gone away voluntarily, I think you will
+soon hear from him."
+
+"What do you mean by--voluntarily?" asked the wife.
+
+"First let me ask you a question," came from Tom. "You said you
+were awakened by a peculiar noise. What sort of a sound was it?"
+
+"Why, a whirring, throbbing noise, like--like--"
+
+She paused for a comparison.
+
+"Like an airship?" asked Tom, with a good deal of eagerness.
+
+"That was it!" cried Mrs. Damon. "I was trying to think where I
+had heard the sound before. It was just like the noise your
+airship makes, Tom!"
+
+"That settles it!" exclaimed the young inventor.
+
+"Settles what?" asked Ned.
+
+"The manner of Mr. Damon's disappearance. He was taken away--or
+went away--in my airship--the airship that was stolen from my shed
+last night!"
+
+Mrs. Damon stared at Tom in amazement.
+
+"Why--why--how could that be?" she asked.
+
+Quickly Tom told of what had happened at his place.
+
+"I begin to see through it," he said. "There is some plot here,
+and we've got to get to the bottom of it. Mr. Damon either went
+with these men in the airship willingly, or he was taken away by
+force. I'm inclined to think he went of his own accord, or you
+would have heard some outcry, Mrs. Damon."
+
+"Well, perhaps so," she admitted. "But would he go away in that
+manner without telling me?"
+
+"He might," said Tom, willing to test his theory on all sides. "He
+might not have wanted you to worry, for you know you dislike him
+to go up an airships."
+
+"Yes, I do. Oh, if I only thought he did go away of his own
+accord, I could understand it. He went, if he did, to try and save
+his fortune."
+
+"It does look as though he had an appointment with someone, Tom,"
+suggested Ned. "His looking at the clock, and then going out, and all
+that."
+
+"Yes," admitted the young inventor, "and now I'm inclined to
+change my theory a bit. It may have been some other airship than
+mine that was used."
+
+"How so?" asked Ned.
+
+"Because the men who took mine were unprincipled fellows. Mr.
+Damon would not have gone away with men who would steal an
+airship."
+
+"Not if he knew it," admitted Ned. "Well, then, let's consider two
+airships--yours and the other that came to keep the appointment
+with Mr. Damon. If the last is true, why should he want to go away
+in an airship at midnight? Why couldn't he take a train, or an
+auto?"
+
+"Well, we don't know all the ins and outs," admitted Tom. "Taking
+a midnight airship ride is rather strange, but that may have been
+the only course open. We'll have to let the explanation go until
+later. At any rate, Mrs. Damon, I feel sure that your husband did
+go off through the air--either in my Eagle or in some other
+craft."
+
+"Well, I'm glad to hear you say so, Tom Swift, though it sounds a
+dreadful thing to say. But if he did go off of his own accord, I
+know he did it for the best. And he may not have told me, for fear
+I would worry. I can understand that. But why isn't he back now?"
+
+Tom had been rather dreading that question. It was one he had
+asked himself, and he had found no good answer for it. If there
+had been such need of haste, that an airship had to be used. why
+had not Mr. Damon come back ere this? Unless, as Tom feared to
+admit, even to himself, there had been some accident.
+
+Half a dozen theories flashed through his mind, but he could not
+select a good, working one,--particularly as there were no clues.
+Disappearing in an airship was the one best means of not leaving a
+trace behind. An auto, a motor boat, a train, a horse and
+carriage--all these could be more or less easily traced. But an
+airship--
+
+If Mr. Damon wanted to cover up his tracks, or if he had been
+taken away, and his captors wanted to baffle pursuit, the best
+means had been adopted.
+
+"Now don't you worry," advised Tom to Mrs. Damon. "I know it looks
+funny, but I think it will come out all right. Ned and I will do
+all we can. Mr. Damon must have known what he was about. But, to
+be on the safe side, we'll send out a general alarm through the
+police."
+
+"Oh, I don't know what I'd done if you hadn't come to help me!"
+exclaimed Mrs. Damon.
+
+"Just you leave it to me!" said the young inventor, cheerfully.
+"I'll find Mr. Damon!"
+
+But, though he spoke thus confidently, Tom Swift had not the
+slightest notion, just then, of how to set about his difficult
+task. He had had hard problems to solve before, so he was not
+going to give up this one. First he wanted to think matters out,
+and arrange a plan of action.
+
+He and Ned made a careful examination of the grounds of the Damon
+homestead. There was little they could learn, though they did find
+where an airship had landed in a meadow, not far away, and where
+it had made a flying start off again.
+
+Carefully Tom looked at the marks made by the wheels of the
+airship.
+
+"They're the same distance apart as those on the Eagle," he said
+to his chum, "and the tires are the same. But that isn't saying
+anything, as lots of airships have the same equipment. So we won't
+jump to any conclusions that way."
+
+Tom and Ned interviewed several of the neighbors, but beyond
+learning that some of them had heard the throbbing of the midnight
+airship, that was as far as they got on that line.
+
+There was nothing more they could do in Waterford, and, leaving
+Mrs. Damon, who had summoned a relative to stay with her, the two
+chums made a quick trip back through the air to Shopton. As
+Eradicate came out to help put away the monoplane Tom noticed that
+the colored man was holding one hand as though it hurt him.
+
+"What's the matter, Rad?" asked the young investor.
+
+"Oh, nuffin--jest natcherly nuffin, Massa Tom."
+
+But Eradicate spoke evasively and in a manner that roused Tom's
+suspicions.
+
+"Boomerang, your mule, didn't kick you; did he?"
+
+"No, sah, Massa Tom, no sah. 'Twern't nuffin laik dat."
+
+"But what was it? Your hand is hurt!"
+
+"Well, Massa Tom, I s'pose I done bettah tell yo' all. I'se had a
+shock!"
+
+"A shock?"
+
+"Yas, sah. A shock. A lickrish shock."
+
+"Oh, you mean an electrical shock. That's too bad. I suppose you
+must have touched a live wire."
+
+"No, sah. 'Twern't dat way."
+
+"How was it, then?"
+
+"Well, yo' see, Massa Tom, I were playin' a joke on Koku."
+
+"Oh, you were; eh? Then I suppose Koku shocked you," laughed Tom.
+
+"No, sah. I--I'll tell you. Dat giant man he were in de telefoam
+boof in de pattern shop--you know--de one where yo' all been
+tryin' to make pishures."
+
+"Yes, I know. Go on!" exclaimed Tom, impatiently.
+
+"Well, he were in dere, Massa Tom, an' I slipped into de boof in
+de next shop--de odder place where yo' all been 'speermentin'. I
+called out on de telefoam, loud laik de Angel Gabriel gwine t'
+holler at de last trump: 'Look out, yo' ole sinnah!' I yell it
+jest t' scare Koku."
+
+"I see," said Tom, a bit severely, for he did not like Eradicate
+interfering with the instruments. "And did you scare Koku?"
+
+"Oh, yas, sah, Massa Tom. I skeered him all right; but suffin else
+done happen. When I put down de telefoam I got a terrible shock.
+It hurts yit!"
+
+"Well," remarked Tom, "I suppose I ought to feel sorry for you,
+but I can't. You should let things alone. Now I've got to see if
+you did any damage. Come along, Ned."
+
+Tom was the first to enter the telephone booth where Eradicate had
+played the part of the Angel Gabriel. He looked at the wires and
+apparatus, but could see nothing wrong.
+
+Then he glanced at the selenium plate, on which he hoped, some
+day, to imprint an image from over the wire. And, as he saw the
+smooth surface he started, and cried.
+
+"Ned! Ned, come here quick!"
+
+"What is it?" asked his chum, Crowding into the booth.
+
+"Look at that plate! Tell me what you see!"
+
+Ned looked.
+
+"Why--why it's Koku's picture!" he gasped.
+
+"Exactly!" cried Tom. "In some way my experiment has succeeded
+when I was away. Eradicate must have made some new connection by
+his monkeying. Ned, it's a success! I've got my first photo
+telephone picture! Hurray!"
+
+
+
+
+
+CHAPTER XIV
+
+MAKING IMPROVEMENTS
+
+
+Tom Swift was so overjoyed and excited that for a few moments he
+capered about, inside the booth, and outside, knocking against his
+chum Ned, clapping him on the back, and doing all manner of boyish
+"stunts."
+
+"It's a success, Ned! I've struck it!" cried Tom, in delight.
+
+"Ouch! You struck ME, you mean!" replied Ned, rubbing his
+shoulder, where the young inventor had imparted a resounding blow
+of joy.
+
+"What of it?" exclaimed Tom. "My apparatus works! I can send a
+picture by telephone! It's great, Ned!"
+
+"But I don't exactly understand how it happened," said Ned, in
+some bewilderment, as he gazed at the selenium plate.
+
+"Neither do I," admitted Tom, when he had somewhat calmed down.
+"That is, I don't exactly understand what made the thing succeed
+now, when it wouldn't work for me a little while ago. But I've got
+to go into that. I'll have to interview that rascal Eradicate, and
+learn what he did when he played that trick on Koku. Yes, and I'll
+have to see Koku, too. We've got to get at the bottom of this,
+Ned."
+
+"I suppose so. You've got your hands full, Tom, with your photo
+telephone, and the disappearance of Mr. Damon."
+
+"Yes, and my own airship, too. I must get after that. Whew! A lot
+of things to do! But I like work, Ned. The more the better."
+
+"Yes, that's like you, Tom. But what are you going to get at
+first?"
+
+"Let me see; the telephone, I think. I'll have Rad and Koku in
+here and talk to them. I say, you Eradicate!" he called out of the
+door of the shop, as he saw the colored man going past, holding
+his shocked arm tenderly.
+
+"Yas, sah, Massa Tom, I'se comin'! What is it yo' all wants, Massa
+Tom?"
+
+"I want you to show me exactly what you did to the wires, and
+other things in here, when you played that Angel Gabriel trick on
+your partner Koku."
+
+"Partner! He ain't mah partner!" exclaimed Eradicate with a scowl,
+for there was not the best of feeling between the two. Eradicate
+had served in the Swift family many years, and he rather resented
+the coming of the giant, who performed many services formerly the
+province of the colored man.
+
+"Well, never mind what he is, Rad," laughed Tom. "You just show me
+what you did. Come now, something happened in here, and I want to
+find out what it was."
+
+"Oh, suffin done happened all right, Massa Tom. Yas, sah! Suffin
+done happened!" cried Eradicate, with such odd emphasis that Tom
+and Ned both laughed.
+
+"An' suffin happened to me," went on the colored man, rubbing his
+shocked arm.
+
+"Well, tell us about it," suggested Tom.
+
+"It was dish yeah way," proceeded Eradicate. And he told more in
+detail how, seeing Koku cleaning and sweeping out the other
+telephone booth, he had thought of the trick to play on him. Both
+telephones had what are called "amplifiers" attached, that could
+be switched on when needed. These amplifiers were somewhat like
+the horn of a phonograph--they increased, or magnified the sound,
+so that one could hear a voice from any part of the shop, and need
+not necessarily have the telephone receiver at his ear.
+
+Seeing Koku near the instrument, Eradicate had switched on the
+amplifier, and had called into his instrument, trying to scare the
+giant. And he did startle Koku, for the loud voice, coming so
+suddenly, sent the giant out of the booth on the run.
+
+"But you must have done something else," insisted Tom. "Look here,
+Rad," and the young inventor pointed to the picture on the plate.
+
+"Mah gracious sakes!" gasped the colored man. "Why dat's Koku
+hisse'f!" and he looked in awe at the likeness.
+
+"That's what you did, Rad!"
+
+"Me? I done dat? No, sah, Massa Tom. I neber did! No, sah!"
+Eradicate spoke emphatically.
+
+"Yes you did, Rad. You took that picture of Koku over my photo
+telephone, and I want you to show me exactly what you did--what
+wires and switches you touched and changed, and all that."
+
+"Yo--yo' done say I tuck dat pishure, Massa Tom?"
+
+"You sure did, Rad."
+
+"Well--well, good land o' massy! An' I done dat!"
+
+Eradicate stared in wonder at the image of the giant on the plate,
+and shook his head doubtingly.
+
+"I--I didn't know I could do it. I never knowed I had it in me!"
+he murmured.
+
+Tom and Ned laughed long and loud, and then the young inventor
+said:
+
+"Now look here, Rad. You've done me a mighty big service, though
+you didn't know it, and I want to thank you. I'm sorry about your
+arm, and I'll have the doctor look at it. But now I want you to
+show me all the things you touched when you played that joke on
+Koku. In some way you did what I haven't been able to do, You took
+the picture. There's probably just one little thing I've
+overlooked, and you stumbled on it by accident. Now go ahead and
+show me."
+
+Eradicate thought for a moment, and then said:
+
+"Well, I done turned on de current, laik I seen you done, Massa
+Tom."
+
+"Yes, go on. You connected the telephone."
+
+"Yas, sah. Den I switched on that flyer thing yo' all has rigged
+up."
+
+"You switched on the amplifier, yes. Go on."
+
+"An'--an' den I plugged in dish year wire," and the colored man
+pointed to one near the top of the booth.
+
+"You switched on that wire, Rad! Why, great Scott, man! That's
+connected to the arc light circuit--it carries over a thousand
+volts. And you switched that into the telephone circuit?"
+
+"Dat's what I done did, Massa Tom; yas, Bah!"
+
+"What for?"
+
+"Why, I done want t' make mah voice good an' loud t' skeer dat
+rascal Koku!"
+
+Tom stared at the colored man in amazement.
+
+"No wonder you got a shock!" exclaimed the young inventor. "You
+didn't get all the thousand volts, for part of it was shunted off;
+but you got a good charge, all right. So that's what did the
+business; eh? It was the combination of the two electrical
+circuits that sent the photograph over the wire."
+
+"I understand it now, Rad; but you did more than I've been able to
+do. I never, in a hundred years, would have thought of switching
+on that current. It never occurred to me. But you, doing it by
+accident, brought out the truth. It's often that way in
+discoveries. And Koku was standing in the other telephone booth,
+near the plate there, when you switched in this current, Rad?"
+
+"Yas, sah, Massa Tom. He were. An' yo' ought t' see him hop when
+he heard mah voice yellin' at him. Ha! ha! ha!"
+
+Eradicate chuckled at the thought. Then a pain in his shocked arm
+made him wince. A wry look passed over his face.
+
+"Yas, sah, Koku done jump about ten feet," he said. "An'--an' den
+I jump too. Ain't no use in denyin' dat fact. I done jump when I
+got dat shock!"
+
+"All right, Rad. You may go now. I think I'm on the right track!"
+exclaimed Tom. "Come on, Ned, we'll try some experiments, and
+we'll see what we can do."
+
+"No shocks though--cut out the shocks, Tom," stipulated his chum.
+
+"Oh, sure! No shocks! Now let's bet busy and improve on
+Eradicate's Angel Gabriel system."
+
+Tom made a quick examination of the apparatus.
+
+"I understand it, I think," he said. "Koku was near the plate in
+the other booth when Rad put on the double current. There was a
+light there, and in an instant his likeness was sent over the
+wire, and imprinted on this plate. Now let's see what we can do.
+You go to that other booth, Ned. I'll see if I can get your
+picture, and send you mine. Here, take some extra selenium plates
+along. You know how to connect them."
+
+"I think so," answered Ned.
+
+"This image is really too faint to be of much use," went on Tom,
+as he looked at the one of Koku. "I think I can improve on it. But
+we're on the right track."
+
+A little later Ned stood in the other booth, while Tom arranged
+the wires, and made the connections in the way accidently
+discovered by Eradicate. The young inventor had put in a new
+plate, carefully putting away the one with the picture of the
+giant, This plate could be used again, when the film, into which
+the image was imprinted, had been washed off.
+
+"All ready, Ned," called Tom, over the wire, when he was about to
+turn the switch. "Stand still, and I'll get you."
+
+The connection was made, and Tom uttered a cry of joy. For there,
+staring at him from the plate in front of him was the face of Ned.
+
+It was somewhat reduced in size, of course, and was not extra
+clear, but anyone who knew Ned could have told he was at the other
+end of the wire.
+
+"Do you get me, Tom?" called Ned, over the telephone.
+
+"I sure do! Now see if you can get me."
+
+Tom made other connections, and then looked at the sending plate
+of his instrument, there being both a sending and receiving plate
+in each booth, just as there was a receiver and a transmitter to
+the telephone.
+
+"Hurray! I see you, Tom!" cried Ned, over the wire. "Say, this is
+great!"
+
+"It isn't as good as I want it," went on Tom. "But it proves that
+I'm right. The photo telephone is a fact, and now persons using
+the wire can be sure of the other person they are conversing with.
+I must tell dad. He wouldn't believe I could do it!"
+
+And indeed Mr. Swift was surprised when Tom proved, by actual
+demonstration, that a picture could be sent over the wire.
+
+"Tom, I congratulate you!" declared the aged inventor. "It is good
+news!"
+
+"Yes, but we have bad news of Mr. Damon," said Tom, and he told
+his father of the disappearance of the eccentric man. Mr. Swift at
+once telephoned his sympathy to Mrs. Damon, and offered to do
+anything he could for her.
+
+"But Tom can help you more than I can," he said. "You can depend
+on Tom."
+
+"I know that," replied Mrs. Damon, over the wire.
+
+And certainly Tom Swift had many things to do now. He hardly knew
+at what to begin first, but now, since he was on the right road in
+regard to his photo telephone, he would work at improving it.
+
+And to this end he devoted himself, after he had sent out a
+general alarm to the police of nearby towns, in regard to the
+disappearance of Mr. Damon. The airship clue, he believed, as did
+the police, would be a good one to work on.
+
+For several days after this nothing of moment occurred. Mr. Damon
+could not be located, and Tom's airship might still be sailing
+above the clouds as far as getting any trace of it was concerned.
+
+Meanwhile the young inventor, with the help of Ned, who was given
+a leave of absence from the bank, worked hard to improve the photo
+telephone.
+
+
+
+
+
+CHAPTER XV
+
+THE AIRSHIP CLUE
+
+
+"Now Ned, we'll try again. I'm going to use a still stronger
+current, and this is the most sensitive selenium plate I've turned
+out yet. We'll see if we can't get a better likeness of you--one
+that will be plainer."
+
+It was Tom Swift who was speaking, and he and his chum had just
+completed some hard work on the new photo telephone. Though the
+apparatus did what Tom had claimed for it, still he was far from
+satisfied. He could transmit over the wire the picture of a person
+talking at the telephone, but the likeness was too faint to make
+the apparatus commercially profitable.
+
+"It's like the first moving pictures," said Tom. "They moved, but
+that was about all they did."
+
+"I say," remarked Ned, as he was about to take his place in the
+booth where the telephone and apparatus were located, "this
+double-strength electrical current you're speaking of won't shock
+me; will it? I don't want what happened to Eradicate to happen to
+me, Tom."
+
+"Don't worry. Nothing will happen. The trouble with Rad was that
+he didn't have the wires insulated when he turned that arc current
+switch by mistake--or, rather, to play his joke. But he's all
+right now."
+
+"Yes, but I'm not going to take any chances," insisted Ned. "I
+want to be insulated myself."
+
+"I'll see to that," promised Tom. "Now get to your booth."
+
+For the purpose of experiments Tom had strung a new line between
+two of his shops, They were both within sight, and the line was
+not very long; but, as I have said, Tom knew that if his apparatus
+would work over a short distance, it would also be successful over
+a long one, provided he could maintain the proper force of
+current, which he was sure could be accomplished.
+
+"And if they can send pictures from Monte Carlo to Paris I can do
+the same," declared Tom, though his system of photo telephony was
+different from sending by a telegraph system--a reproduction of a
+picture on a copper plate. Tom's apparatus transmitted the
+likeness of the living person.
+
+It took some little time for the young inventor, and Ned working
+with him, to fix up the new wires and switch on the current. But
+at last it was complete, and Ned took his place at one telephone,
+with the two sensitive plates before him. Tom did the same, and
+they proceeded to talk over the wire, first making sure that the
+vocal connection was perfect.
+
+"All ready now, Ned! We'll try it," called Tom to his chum, over
+the wire. "Look straight at the plate. I want to get your image
+first, and then I'll send mine, if it's a success,"
+
+Ned did as requested, and in a few minutes he could hear Tom
+exclaim, joyfully:
+
+"It's better, Ned! It's coming out real clear. I can see you
+almost as plainly as if you were right in the booth with me. But
+turn on your light a little stronger."
+
+Tom could hear, through the telephone, his chum moving about, and
+then he caught a startled exclamation.
+
+"What's the matter?" asked Tom anxiously.
+
+"I got a shock!" cried Ned. "I thought you said you had this thing
+fixed. Great Scott, Tom! It nearly yanked the arm off me! Is this
+a joke?"
+
+"No, old man. No, of course not! Something must be wrong. I didn't
+mean that. Wait, I'll take a look. Say, it does seem as if
+everything was going wrong with this invention. But I'm on the
+right track, and soon I'll have it all right. Wait a second. I'll
+be right over."
+
+Tom found that it was only a simple displacement of a wire that
+had given Ned a shock, and he soon had this remedied.
+
+"Now we'll try again," he said. This time nothing wrong occurred,
+and soon Tom saw the clearest image he had yet observed on his
+telephone photo plate.
+
+"Switch me on now, Ned," he called to his chum, and Ned reported
+that he could see Tom very plainly.
+
+"So far--so good," observed Tom, as he came from the booth. "But
+there are several things I want yet to do."
+
+"Such as what?" questioned Ned.
+
+"Well, I want to arrange to have two kinds of pictures come over
+the wire. I want it so that a person can go into a booth, call up
+a friend, and then switch on the picture plate, so he can see his
+friend as well as talk to him. I want this plate to be like a
+mirror, so that any number of images can be made to appear on it.
+In that way it can be used over and over again. In fact it will be
+exactly like a mirror, or a telescope. No matter how far two
+persons may be apart they can both see and talk to one another."
+
+"That's a big contract, Tom."
+
+"Yes, but you've seen that it can be done. Then another thing I
+want to do is to have it arranged so that I can make a photograph
+of a person over a wire."
+
+"Meaning what?"
+
+"Meaning that if a certain person talks to me over the wire, I can
+turn my switch, and get a picture of him here at my apparatus
+connected with my telephone. To do that I'll merely need a sending
+apparatus at the other end of the telephone line--not a receiving
+machine."
+
+"Could you arrange it so that the person who was talking to you
+would have his picture taken whether he wanted it or not?" asked
+Ned.
+
+"Yes, it might be done," spoke Tom, thoughtfully. "I could conceal
+the sending plate somewhere in the telephone booth, and arrange
+the proper light, I suppose."
+
+"That might be a good way in which to catch a criminal," went on
+Ned. "Often crooks call up on the telephone, but they know they
+are safe. The authorities can't see them--they can only hear them.
+Now if you could get a photograph of them while they were
+telephoning--"
+
+"I see!" cried Tom, excitedly. "That's a great idea! I'll work on
+that, Ned."
+
+And, all enthusiasm, Tom began to plan new schemes with his photo
+telephone.
+
+The young inventor did not forget his promise to help Mrs. Damon.
+But he could get absolutely no clue to her husband's whereabouts.
+Mr. Damon had completely and mysteriously disappeared. His
+fortune, too, seemed to have been swallowed up by the sharpers,
+though lawyers engaged by Tom could fasten no criminal acts on Mr.
+Peters, who indignantly denied that he had done anything unlawful.
+
+If he had, he had done it in such a way that he could not be
+brought to justice. The promoter was still about Shopton, as well
+groomed as ever, with his rose in his buttonhole, and wearing his
+silk hat. He still speeded up and down Lake Carlopa in his
+powerful motor boat. But he gave Tom Swift a wide berth.
+
+Late one night, when Tom and Ned had been working at the new photo
+telephone, after all the rest of the household had retired, Tom
+suddenly looked up from his drawings and exclaimed:
+
+"What's that?"
+
+"What's what?" inquired Ned.
+
+"That sound? Don't you hear it? Listen!"
+
+"It's an airship--maybe yours coming back!" cried the young
+banker.
+
+As he spoke Ned did hear, seemingly in the air above the house, a
+curious, throbbing, pulsating sound.
+
+"That's so! It is an airship motor!" exclaimed Tom. "Come on out!"
+
+Together they rushed from the house, but, ere they reached the
+yard, the sound had ceased. They looked up into the sky, but could
+see nothing, though the night was light from a full moon.
+
+"I certainly heard it," said Tom.
+
+"So did I," asserted Ned. "But where is it now?"
+
+They advanced toward the group of work-buildings. Something
+showing white in the moonlight, before the hangar, caught Ned's
+eyes.
+
+"Look!" he exclaimed. "There's an airship, Tom!"
+
+The two rushed over to the level landing place before the big
+shed. And there, as if she had just been run out for a flight, was
+the Eagle. She had come back in the night, as mysteriously as she
+had been taken away.
+
+
+
+
+
+CHAPTER XVI
+
+SUCCESS
+
+
+"Well, this gets me!" exclaimed Tom.
+
+"It sure is strange," agreed Ned. "How did she come here?"
+
+"She didn't come alone--that's sure," went on Tom. "Someone
+brought her here, made a landing, and got away before we could get
+out."
+
+The two chums were standing near the Eagle, which had come back so
+mysteriously.
+
+"Just a couple of seconds sooner and we'd have seen who brought
+her here," went on Tom. "But they must have shut off the motor
+some distance up, and then they volplaned down. That's why we
+didn't hear them."
+
+Ned went over and put his hand on the motor.
+
+"Ouch!" he cried, jumping back. "It's hot!"
+
+"Showing that she's been running up to within a few minutes ago,"
+said Tom. "Well, as I said before, this sure does get me. First
+these mysterious men take my airship, and then they bring her back
+again, without so much as thanking me for the use of her."
+
+"Who in the world can they be?" asked Ned.
+
+"I haven't the least idea. But I'm going to find out, if it's at
+all possible. We'll look the machine over in the morning, and see
+if we can get any clues. No use in doing that now. Come on, we'll
+put her back in the hangar."
+
+"Say!" exclaimed Ned, as a sudden idea came to him. "It couldn't
+be Mr. Damon who had your airship; could it, Tom?"
+
+"I don't know. Why do you ask that?"
+
+"Well, he might have wanted to get away from his enemies for a
+while, and he might have taken your Eagle, and--"
+
+"Mr. Damon wouldn't trail along with a crowd like the one that
+took away my airship," said Tom, decidedly. "You've got another
+guess coming, Ned. Mr. Damon had nothing to do with this."
+
+"And yet the night he disappeared an airship was heard near his
+house."
+
+"That's so. Well, I give up. This is sure a mystery. We'll have a
+look at it in the morning. One thing I'll do, though, I'll
+telephone over to Mr. Damon's house and see if his wife has heard
+any news. I've been doing that quite often of late, so she won't
+think anything of it. In that way we can find out if he had
+anything to do with my airship. But let's run her into the shed
+first."
+
+This was done, and Koku, the giant, was sent to sleep in the
+hangar to guard against another theft. But it was not likely that
+the mysterious men, once having brought the airship back, would
+come for it again.
+
+Tom called up Mrs. Damon on the telephone, but there was no news
+of the missing man. He expressed his sympathy, and said he would
+come and see her soon. He told Mrs. Damon not to get discouraged,
+adding that he, and others, were doing all that was possible. But,
+in spite of this, Mrs. Damon, naturally, did worry.
+
+The next morning the two chums inspected the airship, so
+mysteriously returned to them. Part after part they went over, and
+found nothing wrong. The motor ran perfectly, and there was not so
+much as a bent spoke in the landing wheels. For all that could be
+told by an inspection of the craft she might never have been out
+of the hangar.
+
+"Hello, here's something!" cried Tom, as he got up from the
+operator's seat, where he had taken his place to test the various
+controls.
+
+"What is it?" asked Ned.
+
+"A button. A queer sort of a button. I never had any like that on
+my clothes, and I'm sure you didn't. Look!" and Tom held out a
+large, metal button of curious design.
+
+"It must have come off the coat of one of the men who had your
+airship, Tom," said his chum. "Save it. You may find that it's a
+clue."
+
+"I will. No telling what it may lead to. Well, I guess that's all
+we can find."
+
+And it was. But Tom little realized what a clue the button was
+going to be. Nothing more could be learned by staring at the
+returned airship, so he and Ned went back to the house.
+
+Tom Swift had many things to do, but his chief concern was for the
+photo telephone. Now that he was near the goal of success he
+worked harder than ever. The idea Ned had given him of being able
+to take the picture of a person at the instrument--without the
+knowledge of that person--appealed strongly to Tom.
+
+"That's going to be a valuable invention!" he declared, but little
+he knew how valuable it would prove to him and to others.
+
+It was about a week later when Tom was ready to try the new
+apparatus. Meanwhile he had prepared different plates, and had
+changed his wiring system. In the days that had passed nothing new
+had been learned concerning the whereabouts of Mr. Damon, nor of
+the men who had so mysteriously taken away Tom's airship.
+
+All was in readiness for the trial. Tom sent Ned to the booth that
+he had constructed in the airship hangar, some distance away from
+the house. The other booth Tom had placed in his library, an
+entirely new system of wires being used.
+
+"Now Ned," explained Tom, "the idea is this! You go into that
+booth, just as if it were a public one, and ring me up in the
+regular way. Of course we haven't a central here, but that doesn't
+matter. Now while I'm talking to you I want to see you. You don't
+know that, of course."
+
+"The point is to see if I can get your picture while you're
+talking to me, and not let you know a thing about it."
+
+"Think you can do it, Tom?"
+
+"I'm going to try. We'll soon know. Go ahead."
+
+A little later Ned was calling up his chum, as casually as he
+could, under the circumstances.
+
+"All right!" called Tom to his chum. "Start in and talk. Say
+anything you like--it doesn't matter. I want to see if I can get
+your picture. Is the light burning in your booth?"
+
+"Yes, Tom."
+
+"All right then. Go ahead."
+
+Ned talked of the weather--of anything. Meanwhile Tom was busy.
+Concealed in the booth occupied by Ned was a sending plate. It
+could not be seen unless one knew just where to look for it. In
+Tom's booth was a receiving plate.
+
+The experiment did not take long. Presently Tom called to Ned that
+he need stay there no longer.
+
+"Come on to the house," invited the young inventor, "and we'll
+develope this plate." For in this system it was necessary to
+develope the receiving plate, as is done with an ordinary
+photographic one. Tom wanted a permanent record.
+
+Eagerly the chums in the dark room looked down into the tray
+containing the plate and the developing solution.
+
+"Something's coming out!" cried Ned, eagerly.
+
+"Yes! And it's you!" exclaimed Tom. "See, Ned, I got your picture
+over the telephone. Success! I've struck it! This is the best
+yet!"
+
+At that moment, as the picture came out more and more plainly,
+someone knocked on the door of the dark room.
+
+"Who is it?" asked Tom.
+
+"Gen'man t' see you," said Eradicate. "He say he come from Mistah
+Peters!"
+
+"Mr. Peters--that rascally promoter!" whispered Tom to his chum.
+"What does this mean?"
+
+
+
+
+
+CHAPTER XVII
+
+THE MYSTERIOUS MESSAGE
+
+
+Tom Swift and his chum looked at one another strangely for a
+moment in the dim, red light of the dark room. Then the young
+inventor spoke:
+
+"I'm not going to see him. Tell him so, Rad!"
+
+"Hold on a second," suggested Ned. "Maybe you had better see him,
+Tom. It may have something to with Mr. Damon's lost fortune."
+
+"That's so! I didn't think of that. And I may get a clue to his
+disappearance, though I don't imagine Peters had anything to do
+with that. Wait, Rad. Tell the gentleman I'll see him. Did he give
+any name, Rad?"
+
+"Yas, sah. Him done say him Mistah Boylan."
+
+"The same man who called to see me once before, trying to get me
+to do some business with Peters," murmured Tom. "Very well, I'll
+see him as soon as this picture is fixed. Tell him to wait, Rad."
+
+A little later Tom went to where his caller awaited in the
+library. This time there were no plans to be looked at, the young
+inventor having made a practice of keeping all his valuable papers
+locked in a safe.
+
+"You go into the next room, Ned," Tom had said to his chum. "Leave
+the door open, so you can hear what is said."
+
+"Why, do you think there'll be trouble? Maybe we'd better have
+Koku on hand to--"
+
+"Oh, no, nothing like that," laughed Tom. "I just want you to
+listen to what's said so, if need be, you can be a witness later.
+I don't know what their game is, but I don't trust Peters and his
+crowd. They may want to get control of some of my patents, and
+they may try some underhanded work. If they do I want to be in a
+position to stop them."
+
+"All right," agreed Ned, and he took his place.
+
+But Mr. Boylan's errand was not at all sensational, it would seem.
+He bowed to Tom, perhaps a little distantly, for they had not
+parted the best of friends on a former occasion.
+
+"I suppose you are surprised to see me," began Mr. Boylan.
+
+"Well, I am, to tell the truth," Tom said, calmly.
+
+"I am here at the request of my employer, Mr. Peters," went on the
+caller. "He says he is forming a new and very powerful company to
+exploit airships, and he wants to know whether you would not
+reconsider your determination not to let him do some business for
+you."
+
+"No, I'm afraid I don't care to go into anything like that," said
+Tom.
+
+"It would be a good thing for you," proceeded Mr. Boylan, eagerly.
+"Mr. Peters is able to command large capital, and if you would
+permit the use of your airships--or one of them--as a model, and
+would supervise the construction of others, we could confidently
+expect large sales. Thus you would profit, and I am frank to admit
+that the company, and Mr. Peters, also, would make money. Mr.
+Peters is perfectly free to confess that he is in business to make
+money, but he is also willing to let others share with him. Come
+now, what do you say?"
+
+"I am sorry, but I shall have to say the same thing I said
+before," replied Tom. "Nothing doing!"
+
+Mr. Boylan glanced rather angrily at the young inventor, and then,
+with a shrug of his shoulders, remarked:
+
+"Well, you have the say, of course. But I would like to remind you
+that this is going to be a very large airship company, and if your
+inventions are not exploited some others will be. And Mr. Peters
+also desired me to say that this is the last offer he would make
+you."
+
+"Tell him," said Tom, "that I am much obliged, but that I have no
+business that I can entrust to him. If he wishes to make some
+other type of airship, that is his affair. Good-day."
+
+As Mr. Boylan was going out Tom noticed a button dangling from the
+back of his caller's coat. It hung by a thread, being one of the
+pair usually sewed on the back of a cutaway garment.
+
+"I think you had better take off that button before it falls,"
+suggested Tom. "You may lose it, and perhaps it would be hard to
+match."
+
+"That's so. Thank you!" said Mr. Boylan. He tried to reach around
+and get it, but he was too stout to turn easily, especially as the
+coat was tight-fitting.
+
+"I'll get it for you," offered Tom, as he pulled it off. "There is
+one missing, though," he said, as he handed the button to the man.
+And then Tom started as he saw the pattern of the one in his hand.
+
+"One gone? That's too bad," murmured Mr. Boylan. "Those buttons
+were imported, and I doubt if I can replace them. They are rather
+odd."
+
+"Yes," agreed Tom, gazing as if fascinated at the one he still
+held. "They are rather odd."
+
+And then, as he passed it over, like a flash it came to him where
+he had seen a button like that before. He had found it in his
+airship, which had been so mysteriously taken away and returned.
+
+Tom could hardly restrain his impatience until Mr. Boylan had
+gone. The young inventor had half a notion to produce the other
+button, matching the one he had just pulled off his visitor's
+coat, and tell where he had found it. But he held himself back. He
+wanted to talk first to Ned.
+
+And, when his chum came in, Tom cried:
+
+"Ned, what do you think? I know who had my airship!"
+
+"How?" asked Ned, in wonder.
+
+"By that button clue! Yes, it's the same kind--they're as alike as
+twins!" and Tom brought out the button which he had put away in
+his desk. "See, Boylan had one just like this on the back of his
+coat. The other was missing. Here it is--it was in the seat of my
+airship, where it was probably pulled off as he moved about. Ned,
+I think I've got the right clue at last."
+
+Ned said nothing for several seconds. Then he remarked slowly:
+
+"Well, Tom, it proves one thing; but not the other."
+
+"What do you mean?"
+
+"I mean that it may be perfectly true that the button came off Mr.
+Boylan's coat, but that doesn't prove that he wore it. You can be
+reasonably sure that the coat was having a ride in your Eagle, but
+was Boylan in the coat? That's the question."
+
+"In the coat? Of course he was in it!" cried Tom.
+
+"You can't be sure. Someone may have borrowed his coat to take a
+midnight ride in the airship."
+
+"Mr. Boylan doesn't look to be the kind of a man who would lend
+his clothes," remarked Tom.
+
+"You never can tell. Someone may have borrowed it without his
+knowledge. You'd better go a bit slow, Tom."
+
+"Well, maybe I had. But it's a clue, anyhow."
+
+Ned agreed to this.
+
+"And all I've got to do is to find out who was in the coat when it
+was riding about in my airship," went on Tom.
+
+"Yes," said Ned, "and then maybe you'll have some clue to the
+disappearance of Mr. Damon."
+
+"Right you are! Come on, let's get busy!"
+
+"As if we hadn't been busy all the while!" laughed Ned. "I'll lose
+my place at the bank if I don't get back soon."
+
+"Oh, stay a little longer--a few days," urged Tom. "I'm sure that
+something is going to happen soon. Anyhow my photo telephone is
+about perfected. But I've just thought of another improvement."
+
+"What is it?"
+
+"I'm going to arrange a sort of dictaphone, or phonograph, so I
+can get a permanent record of what a person says over the wire, as
+well as get a picture of him saying it. Then everything will be
+complete. This last won't be hard to do, as there are several
+machines on the market now, for preserving a record of telephone
+conversations. I'll make mine a bit different, though."
+
+"Tom, is there any limit to what you're going to do?" asked Ned,
+admiringly.
+
+"Oh, yes, I'm going to stop soon, and retire," laughed the young
+inventor.
+
+After talking the matter over, Tom and his chum decided to wait a
+day or so before taking any action in regard to the button clue to
+the takers of the airship. After all, no great harm had been done,
+and Tom was more anxious to locate Mr. Damon, and try to get back
+his fortune, as well as to perfect his photo telephone, than he
+was to discover those who had helped themselves to the Eagle.
+
+Tom and Ned put in some busy days, arranging the phonograph
+attachment. It was easy, compared to the hard work of sending a
+picture over the wire. They paid several visits to Mrs. Damon, but
+she had no news of her missing husband, and, as the days went by,
+she suffered more and more under the strain.
+
+Finally Tom's new invention was fully completed. It was a great
+success, and he not only secured pictures of Ned and others over
+the wire, as he talked to them, but he imprinted on wax cylinders,
+to be reproduced later, the very things they said.
+
+It was a day or so after he had demonstrated his new attachment
+for the first time, that Tom received a most urgent message from
+Mrs. Damon.
+
+"Tom," she said, over the telephone, "I wish you would call.
+Something very mysterious has happened."
+
+"Mr. Damon hasn't come back; has he?" asked Tom eagerly.
+
+"No--but I wish I could say he had. This concerns him, however.
+Can you come?"
+
+"I'll be there right away."
+
+In his speedy monoplane Tom soon reached Waterford. Ned did not
+accompany him this time.
+
+"Now what is it, Mrs. Damon?" asked the young inventor.
+
+"About half an hour before I called you," she said, "I received a
+mysterious message."
+
+"Who brought it?" asked Tom quickly.
+
+"No one. It came over the telephone. Someone, whose voice I did
+not know, said to me: 'Sign the land papers, and send them to us,
+and your husband will be released.'"
+
+"That message came over the wire?" cried Tom, excitedly.
+
+"Yes," answered Mrs. Damon. "Oh, I am so frightened! I don't know
+what to do!" and the lady burst into tears.
+
+
+
+
+
+CHAPTER XVIII
+
+ANOTHER CALL
+
+
+Tom Swift, for the moment, did not know what to do. It was a
+strange situation, and one he had never thought of. What did the
+mysterious message mean? He must think it all out, and plan some
+line of action. Clearly Mrs. Damon was not able to do so.
+
+"Now let's get at this in some kind of order," suggested the
+youth, when Mrs. Damon had calmed herself. It was his habit to
+have a method about doing things. "And don't worry," he advised.
+"I am certain some good will come of this. It proves one thing,
+that's sure."
+
+"What is it, Tom?"
+
+"That Mr. Damon is alive and well. Otherwise the message would not
+have said he would be 'released.' It wasn't from anyone you know;
+was it?"
+
+"No, I'm sure I never heard the voice before."
+
+Tom paused a moment to think how useful his photo telephone and
+phonograph arrangement might have been in this case.
+
+"How did the telephone call come in?" inquired the young inventor.
+
+"In the usual way," answered Mrs. Damon. "The bell rang, and, as I
+happened to be near the instrument, I answered it, as I often do,
+when the maid is busy. A voice asked if I was Mrs. Damon, and of
+course I said I was. Then I heard this: 'Sign the land papers, and
+send them to us, and your husband will be released.'"
+
+"Was that all?" Tom asked.
+
+"I think so--I made a note of it at the time." Mrs. Damon looked
+into a small red book. "No, that wasn't all," she said, quickly.
+"I was so astonished, at hearing those strange words about my
+husband, that I didn't know what to say. Before I could ask any
+questions the voice went on to say, rather abruptly: 'We will call
+you again.'"
+
+"That's good!" cried Tom. "I only hope they do it while I am here.
+Perhaps I can get some clue as to who it was called you. But was
+this all you heard?"
+
+"Yes, I'm sure that was all. I had forgotten about the last words,
+but I see I have them written down in my note book."
+
+"Did you ask any questions?" inquired Tom.
+
+"Oh, indeed I did! As soon as I got over being stunned by what I
+heard, I asked all sorts of questions. I demanded to know who was
+speaking, what they meant, where they were, and all that. I begged
+them to tell me something of my husband."
+
+"And what did they say?"
+
+"Not a thing. There wasn't a sound in the telephone. The receiver
+was hung up, breaking the connection after that message to me--
+that mysterious message."
+
+"Yes, it was mysterious," agreed Tom, thoughtfully. "I can't
+understand it. But didn't you try to learn from the central
+operator where the call had come from?"
+
+"Oh, yes, indeed, Tom! As soon as I found out the person speaking
+to me had rung off, I got the girl in the exchange."
+
+"And what did she say?"
+
+"That the call came from an automatic pay station in a drug store
+in town. I have the address. It was one of those telephones where
+you put your money for the call in a slot."
+
+"I see. Well, the first thing to do is for me to go to that drug
+store and find out, if I can, who used the telephone about that
+time. It's a slim chance, but we'll have to take it. Was it a
+man's voice, or a woman's?"
+
+"Oh, a man's, I'm sure. It was very deep and heavy. No woman could
+speak like that."
+
+"So much is settled, anyhow. Now about the land papers--what was
+meant?"
+
+"I'll tell you," said Mrs. Damon. "You know part of our property--
+considerable land and some buildings--is in my name. Mr. Damon had
+it fixed so a number of years ago, in order to protect me. No one
+could get this property, and land, unless I signed the deeds, or
+agreed to sign them. Now all of Mr. Damon's fortune is tied up in
+some of Mr. Peters's companies. That is why my husband has
+disappeared."
+
+"He didn't disappear--he was taken away against his will; I'm
+positive of that!" exclaimed Tom.
+
+"Perhaps so," agreed Mrs. Damon, sadly. "But those are the papers
+referred to, I'm sure."
+
+"Probably," assented Tom. "The rascals want to get control of
+everything--even your possessions. Not satisfied with ruining Mr.
+Damon, they want to make you a beggar, too. So they are playing on
+your fears. They promise to release your husband if you will give
+them the land."
+
+"Yes, that must be it, Tom. What would you advise me to do? I am
+so frightened over this!"
+
+"Do? Don't you do anything!" cried Tom. "We'll fool these rascals
+yet. If they got those papers they might release Mr. Damon, or
+they might not--fearing he would cause their arrest later. But
+we'll have him released anyhow, and we'll save what is left of
+your fortune. Put those land papers in a safe-deposit box, and let
+me do the rest. I'm going to catch those fellows!"
+
+"But how, Tom? You don't know who they are. And a mere message
+over a telephone won't give you a clue to where they are."
+
+"Perhaps not an ordinary message," agreed Tom. "But I'm going to
+try some of my new inventions. You said they told you they were
+going to call again?"
+
+"That's what they said, Tom."
+
+"Well, when they do, I want to be here. I want to listen to that
+message. If you will allow me, I'll take up my residence here for
+a while, Mrs. Damon."
+
+"Allow you? I'll be only too glad if you will, Tom. But I thought
+you were going to try to get some clue from the drug store where
+the mysterious message came from."
+
+"I'll let Ned Newton do that. I want to stay here."
+
+Tom telephoned to Ned to meet him at Mrs. Damon's house, and also
+to bring with him certain things from the laboratory. And when Ned
+arrived in an auto, with various bits of apparatus, Tom put in
+some busy hours.
+
+Meanwhile Ned was sent to the drug store, to see if any clues
+could be obtained there as to who had sent the message. As Tom had
+feared, nothing could be learned. There were several automatic
+'phones in the place, and they were used very often during the day
+by the public. The drug clerks took little or no notice of the
+persons entering or leaving the booths, since the dropping of a
+coin in the slot was all that was necessary to be connected with
+central.
+
+"Well, we've got to wait for the second call here," said Tom, who
+had been busy during Ned's absence. He had fitted to Mrs. Damon's
+telephone a recording wax phonograph cylinder, to get a record of
+the speaker's voice. And he had also put in an extension
+telephone, so that he could listen while Mrs. Damon talked to the
+unknown.
+
+"There, I guess we're ready for them," said Tom, late that
+afternoon. But no queer call came in that day. It was the next
+morning. about ten o'clock, after Mrs. Damon had passed a restless
+night, that the telephone bell rang. Tom, who was on the alert,
+was at his auxiliary instrument in a flash. He motioned to Mrs.
+Damon to answer on the main wire.
+
+"Hello," she spoke into the transmitter. "Who is this?"
+
+"Are you Mrs. Damon?" Tom heard come over the wire in a deep
+voice, and by the manner in which Mrs. Damon signalled the young
+inventor knew that, at the other end of the line, was the
+mysterious man who had spoken before.
+
+
+
+
+
+CHAPTER XIX
+
+THE BUZZING SOUND
+
+
+"Are you Mrs. Damon?" came the question again--rather more
+impatiently this time, Tom thought.
+
+"Yes," answered the lady, glancing over at Tom. The extension
+telephone was in the same room. Softly Tom switched on the
+phonograph attachment. The little wax cylinder began to revolve
+noiselessly, ready to record the faintest word that came over the
+wire.
+
+"You got a message from me yesterday," went on the hoarse voice.
+In vain Tom tried to recall whether or not he had heard it before.
+He could not place it.
+
+"Who are you?" asked Mrs. Damon. She and Tom had previously agreed
+on a line of talk. "Tell me your name, please."
+
+"There's no need for any names to be used," went on the unknown at
+the other end of the wire. "You heard what I said yesterday. Are
+you willing to send me those land title papers, if we release your
+husband?"
+
+"But where shall I send them?" asked Mrs. Damon, to gain time.
+
+"You'll be told where. And listen--no tricks! You needn't try to
+find out who I am, nor where I am. Just send those papers if you
+want to see your husband again."
+
+"Oh, how is he? Tell me about him! You are cruel to keep him a
+prisoner like this! I demand that you release him!"
+
+Tom had not told Mrs. Damon to say this. It came out of her own
+heart--she could not prevent the agonized outburst.
+
+"Never mind about that, now," came the gruff voice over the wire.
+"Are you willing to send the papers?"
+
+Mrs. Damon looked over to Tom for silent instructions. He nodded
+his head in assent.
+
+"Yes, I--I will send them if you tell me where to get them to you
+--if you will release Mr. Damon," said the anxious wife. "But tell
+me who you are--and where you are!" she begged.
+
+"None of that! I'm not looking to be arrested. You get the papers
+ready, and I'll let you know to-morrow, about this time, where to
+send them."
+
+"Wait a minute!" called Mrs. Damon, to gain more time. "I must
+know just what papers you want."
+
+"All right, I'll tell you," and he began to describe the different
+ones.
+
+It took a little time for the unknown to give this information to
+Mrs. Damon. The man was very particular about the papers. There
+were trust deeds, among other things, and he probably thought that
+once he had possession of them, with Mrs. Damon's signature, even
+though it had been obtained under a threat, he could claim the
+property. Later it was learned that such was not the case, for
+Mrs. Damon, with Tom's aid, could have proved the fraud, had the
+scoundrels tried to get the remainder of the Damon fortune.
+
+But at the time it seemed to the helpless woman that everything
+she owned would be taken from her. Though she said she did not
+care, as long as Mr. Damon was restored to her.
+
+As I have said, the telephoning of the instructions about the
+papers took some time. Tom had counted on this, and had made his
+plans accordingly.
+
+As soon as the telephone call had come in, Tom had communicated
+with a private detective who was in waiting, and this man had gone
+to the drug store whence the first call had come. He was going to
+try to make the arrest of the man telephoning.
+
+But for fear the scoundrel would go to a different instrument, Tom
+took another precaution. This was to have one of the operators in
+the central exchange on the watch. As soon as Mrs. Damon's house
+was in connection with another telephone, the location of the
+latter would be noted, and another private detective would be sent
+there. Thus Tom hoped to catch the man at the 'phone.
+
+Meanwhile Tom listened to the hoarse voice at the other end of the
+wire, giving the directions to Mrs. Damon. Tom hoped that soon
+there would be an arrest made.
+
+Meanwhile the talk was being faithfully recorded on the phonograph
+cylinder. And, as the man talked on, Tom became aware of a curious
+undercurrent of sound. It was a buzzing noise, that Tom knew did
+not come from the instrument itself. It was not the peculiar
+tapping, singing noise heard in a telephone receiver, caused by
+induced electrical currents, or by wire trouble.
+
+"This is certainly different," mused Tom. He was trying to recall
+where he had heard the noise before. Sometimes it was faint, and
+then it would gradually increase, droning off into faintness once
+more. Occasionally it was so loud that Mrs. Damon could not hear
+the talk about the papers, and the man would have to repeat.
+
+But finally he came to an end.
+
+"This is all now," he said, sharply. Tom heard the words above the
+queer, buzzing, humming sound. "You are keeping me too long. I
+think you are up to some game, but it won't do you any good, Mrs.
+Damon. I'll 'phone you to-morrow where to send the papers. And if
+you don't send them--if you try any tricks--it will be the worse
+for you and Mr. Damon!"
+
+There was a click, that told of a receiver being placed back on
+the hook, and the voice ceased. So, also, did the queer, buzzing
+sound over which Tom puzzled.
+
+"What can it have been?" he asked. "Did you hear it, Mrs. Damon?"
+
+"What, Tom?"
+
+"That buzzing sound."
+
+"Yes, I heard, but I didn't know what it was. Oh, Tom, what shall
+I do?"
+
+"Don't worry. We'll see if anything happened. They may have caught
+that fellow. If not I'll plan another scheme."
+
+Tom's first act was to call up the telephone exchange to learn
+where the second call had come from. He got the information at
+once. The address was in the suburbs. The man had not gone to the
+drug store this time.
+
+"Did the detective get out to that address?" asked Tom eagerly of
+the manager.
+
+"Yes. As soon as we were certain that he was the party you wanted,
+your man got right after him, Mr. Swift."
+
+"That's good, I hope he catches him!" cried the young inventor. "We'll
+have to wait and find out."
+
+"He said he'd call up and let you know as soon as he reached the
+place," the telephone manager informed Tom.
+
+There was nothing to do but wait, and meanwhile Tom did what he
+could to comfort Mrs. Damon. She was quite nervous and inclined to
+be hysterical, and the youth thought it wise to have a cousin, who
+had come to stay with her, summon the doctor.
+
+"But, Tom, what shall I do about those papers?" Mrs. Damon asked
+him. "Shall I send them?"
+
+"Indeed not!"
+
+"But I want Mr. Damon restored to me," she pleaded. "I don't care
+about the money. He can make more."
+
+"Well, we'll not give those scoundrels the satisfaction of getting
+any money out of you. Just wait now, I'll work this thing out, and
+find a way to catch that fellow. If I could only think what that
+buzzing sound was--"
+
+Then, in a flash, it came to Tom.
+
+"A sawmill! A planing mill!" he cried. "That's what it was! That
+fellow was telephoning from some place near a sawmill!"
+
+The telephone rang in the midst of Tom's excited comments.
+
+"Yes--yes!" he called eagerly. "Who is it--what is it?"
+
+"This is Larsen--the private detective you sent."
+
+"Oh, yes, you were at the drug store."
+
+"Yes, Mr. Swift. Well, that party didn't call up from here."
+
+"I know, Larsen. It was from another station. We're after him.
+Much obliged to you. Come on back."
+
+Tom was sure his theory was right. The man had called up the Damon
+house from some telephone near a sawmill. And a little later Tom's
+theory was proved to be true. He got a report from the second
+detective. Unfortunately the man had not been able to reach the
+telephone station before the unknown speaker had departed.
+
+"Was the place near a sawmill?" asked Tom, eagerly.
+
+"It was," answered the detective over the wire. "The telephone is
+right next door to one. It's an automatic pay station and no one
+seems to have noticed who the man was who telephoned. I couldn't
+get a single clue. I'm sorry."
+
+"Never mind," said Tom, as cheerfully as he could. "I think I'm on
+the right track now. I'm going to lay a trap for this fellow."
+
+
+
+
+
+CHAPTER XX
+
+SETTING THE TRAP
+
+
+Troublesome problems seemed to be multiplying for Tom Swift. He
+admitted as much himself after the failure to capture the man who
+had telephoned to Mrs. Damon. He had hoped that his plan of
+sending detectives to the location of the telephones would
+succeed. Since it had not the youth must try other means.
+
+"Now, Ned," he said to his chum, when they were on their way from
+Mrs. Damon's, it being impossible to do anything further there.
+"Now, Ned, we've got to think this thing out together."
+
+"I'm willing, Tom. I'll do what I can."
+
+"I know you will. Now the thing to do is to go at this thing
+systematically. Otherwise we'll be working around in a circle, and
+won't get anywhere. In the first place, let's set down what we do
+know. Then we'll put down what we don't know, and go after that."
+
+"Put down what you don't know?" exclaimed Ned. "How are you going
+to put down a thing when you don't know it?"
+
+"I mean we can put a question mark after it, so to speak. For
+instance we don't know where Mr. Damon is, but we want to find
+out."
+
+"Oh, I see. Well, let's start off with the things we do know."
+
+The two friends were at Tom's house by now, having come from
+Waterford in Tom's airship. After thinking over all the exciting
+happenings of the past few days, Tom remarked: "Now, Ned, for the
+things we do know. In the first place Mr. Damon is missing, and
+his fortune is about gone. There is considerable left to Mrs.
+Damon, however, but those scoundrels may get that away from her,
+if we don't watch out. Secondly, my airship was taken and brought
+back, with a button more than it had when it went away. Said
+button exactly matched one off Mr. Boylan's coat."
+
+"Thirdly, Mr. Damon was either taken away or went away, in an
+airship--either in mine or someone else's. Fourthly, Mrs. Damon
+has received telephonic communications from the man, or men, who
+have her husband. Fifthly, Mr. Peters, either legally or
+illegally, is responsible for the loss of Mr. Damon's fortune.
+Now: there you are--for the things we do know."
+
+"Now for the things we don't know. We don't know who has taken
+Mr. Damon away, nor where he is, to begin with the most important."
+
+"Hold on, Tom, I think you're wrong," broke in Ned.
+
+"In what way?"
+
+"About not knowing who is responsible for the taking away of Mr.
+Damon. I think it's as plain as the nose on your face that Peters
+is responsible."
+
+"I can't see it that way," said Tom, quickly. "I will admit that
+it looks as though Boylan had been in my airship, but as for
+Peters taking Mr. Damon away--why, Peters is around town all the
+while, and if he had a hand in the disappearance of Mr. Damon, do
+you think he'd stay here, when he knows we are working on the
+case? And would he send Boylan to see me if Boylan had been one of
+those who had a hand in it? They wouldn't dare, especially as they
+know I'm working on the case."
+
+"Peters is a bad lot. I'll grant you, though, he was fair enough
+to pay for my motor boat. I don't believe he had anything to do
+with taking Mr. Damon away."
+
+"Do you think he was the person who was talking to Mrs. Damon
+about the papers?"
+
+"No, Ned. I don't. I listened to that fellow's voice carefully. It
+wasn't like Peters's. I'm going to put it in the phonograph, too,
+and let you listen to it. Then see what you say."
+
+Tom did this, a little later. The record of the voice, as it came
+over the wire, was listened to from the wax cylinder, and Ned had
+to admit that it was not much like that of the promoter.
+
+"Well, what's next to be done?" asked the young banker.
+
+"I'm going to set a trap," replied Tom, with a grin.
+
+"Set a trap?"
+
+"Yes, a sort of mouse-trap. I'm glad my photo telephone is now
+perfected, Ned."
+
+"What has that got to do with it?"
+
+"That's going to be my trap, Ned. Here is my game. You know this
+fellow--this strange unknown--is going to call up Mrs. Damon
+to-morrow. Well, I'll be ready for him. I'm going to put in the booth
+where he will telephone from, one of my photo telephones--that is, the
+sending apparatus. In Mrs. Damon's house, attached to her telephone,
+will be the receiving plate, as well as the phonograph cylinder."
+
+"When this fellow starts to talk he'll be sending us his picture,
+though he won't know it, and we'll be getting a record of his
+voice. Then we'll have him just where we want him."
+
+"Good!" cried Ned. "But, Tom, there's a weak spot in your mouse-
+trap."
+
+"What is it?"
+
+"How are you going to know which telephone the unknown will call
+up from? He may go to any of a hundred, more or less."
+
+"He might--yes. But that's a chance we've got to take. It isn't so
+much of a chance, though when you stop to think that he will
+probably go to some public telephone in an isolated spot, and,
+unless I'm much mistaken he will go to a telephone near where he
+was to-day. He knows that was safe, since we didn't capture him,
+and he's very likely to come back."
+
+"But to make the thing as sure as possible, I'm going to attach my
+apparatus to a number of public telephones in the vicinity of the
+one near the sawmill. So if the fellow doesn't get caught in one,
+he will in another. I admit it's taking a chance; but what else
+can we do?"
+
+"I suppose you're right, Tom. It's like setting a number of
+traps."
+
+"Exactly. A trapper can't be sure where he is going to get his
+catch, so he picks out the place, or run-way, where the game has
+been in the habit of coming. He hides his traps about that place,
+and trusts to luck that the animal will blunder into one of them."
+
+"Criminals, to my way of thinking, are a good bit like animals.
+They seem to come back to their old haunts. Nearly any police
+story proves this. And it's that on which I am counting to capture
+this criminal. So I'm going to fit up as many telephones with my
+photo and phonograph outfit, as I can in the time we have. You'll
+have to help me. Luckily I've got plenty of selenium plates for
+the sending end. I'll only need one at the receiving end. Now
+we'll have to go and have a talk with the telephone manager, after
+which we'll get busy."
+
+"You've overlooked one thing, Tom."
+
+"What's that, Ned?"
+
+"Why, if you know about which telephone this fellow is going to
+use, why can't you have police stationed near it to capture him as
+soon as he begins to talk?"
+
+"Well, I did think of that, Ned; but it won't work."
+
+"Why not?"
+
+"Because, in the first place this man, or some of his friends,
+will be on the watch. When he goes into the place to telephone
+there'll be a look-out, I'm sure, and he'd either put off talking
+to Mrs. Damon, or he'd escape before we had any evidence against
+him."
+
+"You see I've got to get evidence that will stand in the courts to
+convict this fellow, and if he's scared off before we get that,
+the game will be up."
+
+"That's what my photo telephone will do--it will get the evidence,
+just as a dictaphone does. In fact, I'm thinking of working it out
+on those lines, after I clear up this business."
+
+"Just suppose we had detectives stationed at all the telephones
+near the sawmill, where this fellow would be likely to go. In the
+first place no one has seen him, as far as we know, so there's no
+telling what sort of a chap he is. And you can't go up to a
+perfect stranger and arrest him because you think he is the man
+who has spirited away Mr. Damon."
+
+"Another thing. Until this fellow has talked, and made his offer
+to Mrs. Damon, to restore her husband, in exchange for certain
+papers, we have no hold over him."
+
+"But he has done that, Tom. You heard him, and you have his voice
+down on the wax cylinder."
+
+"Yes, but I haven't had a glimpse of his face. That's what I want,
+and what I'm going to get. Suppose he does go into the telephone
+booth, and tell Mrs. Damon an address where she is to send the
+papers. Even if a detective was near at hand he might not catch
+what was said. Or, if he did, on what ground could he arrest a man
+who, very likely, would be a perfect stranger to him? The
+detective couldn't say: 'I take you into custody for telephoning
+an address to Mrs. Damon.' That, in itself, is no crime."
+
+"No, I suppose not," admitted Ned. "You've got this all thought
+out, Tom."
+
+"I hope I have. You see it takes quite a combination to get
+evidence against a criminal--evidence that will convict him.
+That's why I have to be so careful in setting my trap."
+
+"I see, Tom. Well, it's about time for us to get busy; isn't it?"
+
+"It sure is. There's lots to do. First we'll go see the telephone
+people."
+
+Tom explained to the 'phone manager the necessity for what he was
+about to do. The manager at once agreed to let the young inventor
+have a free hand. He was much interested in the photo telephone,
+and Tom promised to give his company a chance to use it on their
+lines, later.
+
+The telephone near the sawmill was easily located. It was in a
+general store, and the instrument was in a booth. To this
+instrument Tom attached his sending plate, and he also substituted
+for the ordinary incandescent light, a powerful tungsten one, that
+would give illumination enough to cause the likeness to be
+transmitted over the wire.
+
+The same thing was done to a number of the public telephones in
+that vicinity, each one being fitted up so that the picture of
+whoever talked would be transmitted over the wire when Tom turned
+the switch. To help the plan further the telephone manager marked
+a number of other 'phones, "Out of Order," for the time being.
+
+"Now, I think we're done!" exclaimed the young inventor, with a
+sigh, late that night. He and Ned and the line manager had worked
+hard.
+
+"Yes," answered the young banker, "the traps are set. The question
+is: Will our rat be caught?"
+
+
+
+
+
+CHAPTER XXI
+
+THE PHOTO TELEPHONE
+
+
+Tom Swift was taking, as he afterward confessed, "a mighty big
+chance." But it seemed the only way. He was working against
+cunning men, and had to be as cunning as they.
+
+True, the man he hoped to capture, through the combination of his
+photo telephone and the phonograph, might go to some other
+instrument than one of those Tom had adjusted. But this could not
+be helped. In all he had put his new attachment on eight 'phones
+in the vicinity of the sawmill. So he had eight chances in his
+favor, and as many against him as there were other telephones in
+use.
+
+"It's a mighty small margin in our favor," sighed Tom.
+
+"It sure is," agreed Ned. They were at Mrs., Damon's house,
+waiting for the call to come in.
+
+"But we couldn't do anything else," went on Tom.
+
+"No," spoke Ned, "and I have a great deal of hope in the
+proverbial Swift luck, Tom."
+
+"Well, I only hope it holds good this time!" laughed the young
+inventor.
+
+"There are a good many things that can go wrong," observed Ned.
+"The least little slip-up may spoil your traps, Tom."
+
+"I know it, Ned. But I've got to take the chance. We've just got
+to do something for Mrs. Damon. She's wearing herself out by
+worrying," he added in a low voice, for indeed the wife of his
+friend felt the absence of her husband greatly. She had lost
+flesh, she ate scarcely anything, and her nights were wakeful ones
+of terror.
+
+"What if this fails?" asked Ned.
+
+"Then I'm going to work that button clue to the limit," replied
+Tom. "I'll go to Boylan and see what he and Peters have to say."
+
+"If you'd done as I suggested you'd have gone to them first,"
+spoke Ned. "You'll find they're mixed up in this."
+
+"Maybe; but I doubt it. I tell you there isn't a clue leading to
+Peters--as yet."
+
+"But there will be," insisted Ned. "You'll see that that I'm right
+this time."
+
+"I can't see it, Ned. As a matter of fact, I would have gone to
+Boylan about that button I found in my airship only I've been so
+busy on this photo telephone, and in arranging the trap, that I
+haven't had time. But if this fails--and I'm hoping it won't--I'll
+get after him," and there was a grim look on the young inventor's
+face.
+
+It was wearying and nervous work--this waiting. Tom and Ned felt
+the strain as they sat there in Mrs. Damon's library, near the
+telephone. It had been fitted up in readiness. Attached to the
+receiving wires was a sensitive plate, on which Tom hoped would be
+imprinted the image of the man at the other end of the wire--the
+criminal who, in exchange for the valuable land papers, would give
+Mr. Damon his liberty.
+
+There was also the phonograph cylinder to record the man's voice.
+Several times, while waiting for the call to come in, Tom got up
+to test the apparatus. It was in perfect working order.
+
+As before, there was an extension telephone, so that Mrs. Damon
+could talk to the unknown, while Tom could hear as well. But he
+planned to take no part in the conversation unless something
+unforeseen occurred.
+
+Mr. Damon was an enthusiastic photographer, and he had a dark room
+adjoining his library. It was in this dark room that Tom planned
+to develop the photo telephone plate.
+
+On this occasion he was not going to use the metal plate in which,
+ordinarily, the image of the person talking appeared. That record
+was but a fleeting one, as in a mirror. This time Tom wanted a
+permanent picture that could, if necessary, be used in a court of
+justice.
+
+Tom's plan was this: If the person who had demanded the papers
+came to one of the photo telephones, and spoke to Mrs. Damon, Tom
+would switch on the receiving apparatus. Thus, while the man was
+talking, his picture would be taken, though he would not know of
+the thing being done.
+
+His voice would also be recorded on the wax cylinder, and he would
+be equally unaware of this.
+
+When Tom had imprinted the fellow's image on the prepared plate,
+he would go quickly to the dark room and develop it. A wet print
+could be made, and with this as evidence, and to use in
+identification, a quick trip could be made to the place whence the
+man had telephoned. Tom hoped thus to capture him.
+
+To this end he had his airship in waiting, and as soon as he had
+developed the picture he planned to rush off to the vicinity of
+the sawmill, and make a prisoner of the man whose features would
+be revealed to him over the wire.
+
+It was a hazardous plan--a risky one--but it was the best that he
+could evolve. Tom had instructed Mrs. Damon to keep the man in
+conversation as long as possible, in order to give the young
+inventor himself time to rush off in his airship. But of course
+the man might get suspicious and leave. That was another chance
+that had to be taken.
+
+"If I had thought of it in time," said Tom, musingly, as he paced
+up and down in the library waiting for the 'phone to ring, "if I
+had thought of it in time I would have rigged up two plates--one
+for a temporary, or looking-glass, picture, and the other for a
+permanent one. In that way I could rush off as soon as I got a
+glimpse of the fellow. But it's too late to do that now. I'll have
+to develop this plate."
+
+Waiting is the most wearisome work there is. Tom and Ned found
+this to be the case, as they sat there, hoping each moment that
+the telephone bell would ring, and that the man at the other end
+of the wire would be the mysterious stranger. Mrs. Damon, too,
+felt the nervous strain.
+
+"This is about the hour he called up yesterday," said Tom, in a
+low voice, after coming back from a trip to the window to see that
+his airship was in readiness. He had brought over to help in
+starting it, for he was using his most powerful and speedy craft,
+and the propellers were hard to turn.
+
+"Yes," answered Mrs. Damon. "It was just about this hour, Tom. Oh,
+I do hope--"
+
+She was interrupted by the jingle of the telephone bell. With a
+jump Tom was at the auxiliary instrument, while Mrs. Damon lifted
+off the receiver of her own telephone.
+
+"Yes; what is it?" she asked, in a voice that she tried to make
+calm.
+
+"Do you know who this is?" Tom heard come over the wire.
+
+"Are you the--er--the person who was to give me an address where I
+am to send certain papers?"
+
+"Yes. I'm the same one. I'm glad to see that you have acted
+sensibly. If I get the papers all right, you'll soon have your
+husband back. Now do as I say. Take down this address."
+
+"Very well," assented Mrs. Damon. She looked over at Tom. He was
+intently listening, and he, too, would note the address given. The
+trap was about to be sprung. The game had walked into it. Just
+which telephone was being used Tom could not as yet tell. It was
+evidently not the one nearest the planing mill, for Tom could not
+hear the buzzing sound. It was well he had put his attachment on
+several instruments.
+
+"One moment, please," said Mrs. Damon, to the unknown at the other
+end of the wire. This was in accordance with the pre-arranged
+plan.
+
+"Well, what is it?" asked the man, impatiently. "I have no time to
+waste."
+
+Tom heard again the same gruff tones, and he tried in vain to
+recognize them.
+
+"I want you take down a message to Mr. Damon," said his wife.
+"This is very important. It can do you no harm to give him this
+message; but I want you to get it exact. If you do not promise to
+deliver it I shall call all negotiations off."
+
+"Oh, all right I'll take the message; but be quick about it. Then
+I'll give you the address where you are to send the papers."
+
+"This is the message," went on Mrs. Damon. "Please write it down.
+It is very important to me. Have you a pencil?"
+
+"Yes, I have one. Wait until I get a bit of paper. It's so dark in
+this booth--wait until I turn on the light."
+
+Tom could not repress a pleased and joyful exclamation. It was
+just what he had hoped the man would do--turn on the light in the
+booth. Indeed, it was necessary for the success of the trap that
+the light be switched on. Otherwise no picture could be
+transmitted over the wire. And the plan of having the man write
+down a message to Mr. Damon was arranged with that end in view.
+The man would need a light to see to write, and Tom's apparatus
+must be lighted in order to make it work. The plot was coming
+along finely.
+
+"There!" exclaimed the man at the other end of the wire. "I have a
+light now. Go ahead with your message, Mrs. Damon. But make it
+short. I can't stay here long."
+
+Then Mrs. Damon began dictating the message she and Tom had agreed
+upon. It was as long as they dared make it, for they wanted to
+keep the man in the booth to the last second.
+
+"Dear Husband," began Mrs. Damon. What the message was does not
+matter. It has nothing to do with this story. Sufficient to say
+that the moment the man began writing it down, as Tom could tell
+over the sensitive wire, by the scratching of the pencil--at that
+moment Tom, knowing the light was on in the distant telephone
+booth, switched on the picture-taking apparatus. His receiving
+apparatus at once indicated that the image was being made on the
+sensitive plate.
+
+It took only a few seconds of time, and with the plate in the
+holder Tom hastened to the dark room to develop it. Ned took his
+chum's place at the telephone, to see that all worked smoothly.
+The photo telephone had done it's work. Whose image would be found
+imprinted on the sensitive plate? Tom's hands trembled so that he
+could scarcely put it in the developing solution.
+
+
+
+
+
+CHAPTER XXII
+
+THE ESCAPE
+
+
+Ned Newton, listening at the auxiliary telephone heard the man, to
+whom Mrs. Damon was dictating her message to her husband, utter an
+exclamation of impatience.
+
+"I'm afraid I can't take down any more," he called. "That is
+enough. Now you listen. I want you to send me those papers."
+
+"And I am willing to," went on Mrs. Damon, while Ned listened to
+the talk, the phonograph faithfully recording it.
+
+"I wonder whose picture Tom will find," mused Ned.
+
+The unknown, at the other end of the wire, began giving Mrs. Damon
+a description of just what papers he wanted, and how to mail them
+to him. He gave an address that Ned recognized as that of a cigar
+store, where many persons received their mail under assumed names.
+The postal authorities had, for a long time, tried to get evidence
+against it
+
+"That's going to make it hard to get him, when he comes for the
+papers," thought Ned. "He's a foxy criminal, all right. But I
+guess Tom will turn the trick."
+
+Mrs. Damon was carefully noting down the address. She really
+intended to send the papers, if it proved that there was no other
+way in which she could secure the release of her husband. But she
+did not count on all of Tom's plans. "Why doesn't he develop that
+plate?" thought Ned. "He'll be too late, in spite of his airship.
+That fellow will skip."
+
+It was at that moment that Tom came into the library. He moved
+cautiously, for he realized that a loud sound in the room would
+carry to the man at the other end of the wire. Tom motioned for
+Ned to come to him. He held out a dripping photographic plate.
+
+"It's Peters!" said Tom, in a hoarse whisper.
+
+"Peters?" gasped Ned. "How could it be? His voice--"
+
+"I know. It didn't sound a bit like Peters over the 'phone, but
+there's his picture, all right!"
+
+Tom held up the plate. There, imprinted on it by the wonderful
+power of the young inventor's latest appliance, was the image of
+the rascally promoter. As plainly as in life he was shown, even to
+his silk hat and the flower in his button-hole. He was in a
+telephone booth--that much could be told from the photograph that
+had been transmitted over the wire, but which booth could not be
+said--they were nearly all alike.
+
+"Peters!" gasped Ned. "I thought he was the fellow, Tom."
+
+"Yes, I know. You were right, and I was wrong. But I did not
+recognize his voice. It was very hoarse. He must have a bad cold."
+Later this was learned to have been the case. "There's no time to
+lose," whispered Tom, while Mrs. Damon was doing her best to
+prolong the conversation in order to hold the man at the other end
+of the wire. "Ned, get central on the other telephone, and see
+where this call came from. Then we'll get there as fast as the
+airship will take us."
+
+A second and temporary telephone line had been installed in the
+Damon home, and on this Ned was soon talking, while Tom, putting
+the photographic plate away for future use, rushed out to get his
+airship in shape for a quick flight. He had modified his plans.
+Instead of having a detective take a print of the photo telephone
+image, and make the arrest, Tom was going to try to capture Peters
+himself. He believed he could do it. One look at the wet plate was
+enough. He knew Peters, though it upset some of his theories to
+learn that it was the promoter who was responsible for Mr. Damon's
+disappearance.
+
+The man at the other end of the wire was evidently getting
+impatient. Possibly he suspected some trick. "I've got to go now,"
+he called to Mrs. Damon. "If I don't get those papers in the
+morning it will be the worse for Mr. Damon."
+
+"Oh, I'll send you the papers," she said.
+
+By this time Ned had gotten into communication with the manager of
+the central telephone exchange, and had learned the location of
+the instrument Peters was using. It was about a mile from the one
+near the sawmill.
+
+"Come on!" called Tom to his chum, as the latter gave him this
+information. "The Firefly is tuned up for a hundred miles an hour!
+We'll be there in ten minutes! We must catch him red-handed, if
+possible!"
+
+"He's gone!" gasped Mrs. Damon as she came to the outer door, and
+watched Tom and Ned taking their places in the airship, while Koku
+prepared to twirl the propellers.
+
+"Gone!" echoed Tom, blankly.
+
+"Yes, he hung up the receiver."
+
+"See if you can't get him back," suggested the young inventor.
+"Ask Central to ring that number again. We'll be there in a jiffy.
+Maybe he'll come to the telephone again. Or he may even call up
+his partners and tell them the game is working his way. Try to get
+him back, Mrs. Damon."
+
+"I will," she said.
+
+And, as she hurried back to the instrument, Tom and Ned shot up
+toward the blue sky in an endeavor to capture the man at the other
+telephone.
+
+"And to think it was Peters!" cried Tom into Ned's ear, shouting
+to be heard above the roar of the motor exhaust.
+
+"I thought he'd turn out to be mixed up in the affair," said Ned.
+
+"Well, you were right. I was off, that time," admitted Tom, as he
+guided his powerful craft above the trees. "I was willing to admit
+that he had something to do with Mr. Damon's financial trouble,
+but as for kidnapping him--well, you never can tell."
+
+They drove on at a breath-catching pace, and it seemed hardly a
+minute after leaving Mrs. Damon's house before Tom called:
+
+"There's the building where the telephone is located."
+
+"And now for that rascal Peters!" cried Ned.
+
+The airship swooped down, to the great astonishment of some
+workmen nearby.
+
+Hardly had the wheels ceased revolving on the ground, as Tom made
+a quick landing, than he was out of his seat, and running toward
+the telephone. He knew the place at once from having heard Ned's
+description, and besides, this was one of the places where he had
+installed his apparatus.
+
+Into the store Tom burst, and made a rush for the 'phone booth. He
+threw open the door. The place was empty!
+
+"The man--the man who was telephoning!" Tom called to the
+proprietor of the place.
+
+"You mean that big man, with the tall hat, who was in there so
+long?"
+
+"Yes, where is he?"
+
+"Gone. About two minutes ago."
+
+"Which way?"
+
+"Over toward Shopton, and in one of the fastest autos that ever
+scattered dust in this section."
+
+"He's escaped us!" said Tom to Ned. "But we'll get him yet! Come
+on!"
+
+"I'm with you. Say, do you know what this looks like to me?"
+
+"What?"
+
+"It looks as if Peters was scared and was going to run away to
+stay!"
+
+
+
+
+
+CHAPTER XXIII
+
+ON THE TRAIL
+
+
+Such a crowd had quickly gathered about Tom's airship that it was
+impossible to start it. Men and boys, and even some girls and
+women, coming from no one knew where, stood about the machine,
+making wondering remarks about it.
+
+"Stand back, if you please!" cried Tom, good-naturedly. "We've
+got to get after the fellow in the auto."
+
+"You'll have hard work catching him, friend, in that rig,"
+remarked a man. "He was fracturing all the speed laws ever passed.
+I reckon he was going nigh onto sixty miles an hour."
+
+"We can make a hundred," spoke Ned, quietly.
+
+"A hundred! Get out!" cried the man. "Nothing can go as fast as
+that!"
+
+"We'll show you, if we once get started," said Tom. "I guess we'll
+have to get one of these fellows to twirl the propellers for us,
+Ned," he added. "I didn't think, or I'd have brought the self-
+starting machine," for this one of Tom's had to be started by
+someone turning over the propellers, once or twice, to enable the
+motor to begin to speed. On some of his aircraft the young
+inventor had attached a starter, something like the ones on the
+newest autos.
+
+"What are you going to do?" asked Ned, as Tom looked to the
+priming of the cylinders.
+
+"I'm going to get on the trail of Peters," he said. "He's at the
+bottom of the whole business; and it's a surprise to me. I'm going
+to trail him right down to the ground now, and make him give up
+Mr. Damon and his fortune,"
+
+"But you don't know where he is, Tom."
+
+"I'll find out. He isn't such an easy man to miss--he's too
+conspicuous. Besides, if he's just left in his auto we may catch
+him before he gets to Shopton."
+
+"Do you think he's going there?"
+
+"I think so. And I think, Ned, that he's become suspicious and
+will light out. Something must have happened, while he was
+telephoning, and he got frightened, as big a bluff as he is. But
+we'll get him. Come on! Will you turn over the propellers, please?
+I'll show you how to do it," Tom went on to a big, strong man
+standing close to the blades.
+
+"Sure I'll do it," was the answer. "I was a helper once at an
+airship meet, and I know how."
+
+"Get back out of the way in time," the young inventor warned him.
+"They start very suddenly, sometimes."
+
+"All right, friend, I'll watch out," was the reply, and with Tom
+and Ned in their seats, the former at the steering wheel, the
+craft of the air was soon throbbing and trembling under the first
+turn, for the cylinders were still warm from the run from Mrs.
+Damon's house.
+
+The telephone was in an outlying section of Waterford--a section
+devoted in the main to shops and factories, and the homes of those
+employed in various lines of manufacture. Peters had chosen his
+place well, for there were many roads leading to and from this
+section, and he could easily make his escape.
+
+"But we'll get after him," thought Tom, grimly, as he let the
+airship run down the straight road a short distance on the bicycle
+wheels, to give it momentum enough so that it would rise.
+
+Then, with the tilting of the elevation rudder, the craft rose
+gracefully, amid admiring cheers from the crowd. Tom did not go up
+very far, as he wanted to hover near the ground, to pick out the
+speeding auto containing Peters.
+
+But this time luck was not with Tom. He and Ned did sight a number
+of cars speeding along the highway toward Shopton, but when they
+got near enough to observe the occupants they were disappointed
+not to behold the man they sought. Tom circled about for some
+time, but it was of no use, and then he headed his craft back
+toward Waterford.
+
+"Where are you going?" asked Ned, yelling the words into the ear
+of his chum.
+
+"Back to Mrs. Damon's," answered Tom, in equally loud tones.
+
+It was impossible to talk above the roaring and throbbing of the
+motor, so the two lads kept silent until the airship had landed
+near Mrs. Damon's home.
+
+"I want to see if Mrs. Damon is all right," Tom explained, as he
+jumped from the still moving machine. "Then we'll go to Shopton,
+and cause Peters's arrest. I can make a charge against him now,
+and the evidence of the photo telephone will convict him, I'm
+sure. And I also want to see if Mrs. Damon has had any other
+word."
+
+She had not, however, though she was more nervous and worried than
+ever.
+
+"Oh, Tom, what shall I do?" she exclaimed. "I am so frightened!
+What do you suppose they will do to Mr. Damon?"
+
+"Nothing at all!" Tom assured her. "He will be all right. I think
+matters are coming to a crisis now, and very likely he'll be with
+you inside of twenty-four hours. The game is up, and I guess
+Peters knows it. I'm going to have him arrested at once."
+
+"Shall I send those land papers, Tom?"
+
+"Indeed you must not! But I'll talk to you about that later. Just
+put away that phonograph record of Peters's talk. I'll take along
+the photo telephone negative, and have some prints made--or, I
+guess, since we're going in the airship, that I'd better leave it
+here for the present. We'll use it as evidence against Peters.
+Come on, Ned."
+
+"Where to now?"
+
+"Peters's house. He's probably there, arranging to cover up his
+tracks when he lights out."
+
+But Shallock Peters did better than merely cover up his tracks. He
+covered himself up, so to speak. For when Ned and Tom, after a
+quick flight in the airship, reached his house, the promoter had
+left, and the servants, who were quite excited, did not know where
+he had gone.
+
+"He just packed up a few clothes and ran out," said one of the
+maids. "He didn't say anything about our wages, either, and he
+owes me over a month."
+
+"Me too," said another.
+
+"Well, if he doesn't pay me some of my back wages soon, I'll sue
+him!" declared the gardener. "He owes me more than three months,
+but he kept putting me off."
+
+And, so it seemed, Peters had done with several of his employes.
+When the promoter came to Shopton he had taken an elaborate house
+and engaged a staff of servants. Peters was not married, but he
+gave a number of entertainments to which the wealthy men of
+Shopton and their wives came. Later it was found that the bills
+for these had never been paid. In short, Peters was a "bluff" in
+more ways than one.
+
+Tom told enough of his story to the servants to get them on his
+side. Indeed, now that their employer had gone, and under such
+queer circumstances, they had no sympathy for him. They were only
+concerned about their own money, and Tom was given admittance to
+the house.
+
+Tom made a casual search, hoping to find some clue to the
+whereabouts of Mr. Damon, or to get some papers that would save
+his fortune. But the search was unsuccessful.
+
+There was a safe in the room Peters used for an office, but when
+Tom got there the strong box was open, and only some worthless
+documents remained.
+
+"He smelled a rat, all right," said Tom, grimly. "After he
+telephoned to Mrs. Damon something happened that gave him an
+intimation that someone was after him. So he got away as soon as
+he could."
+
+"But what are you going to do about it, Tom?"
+
+"Get right after him. He can't have gotten very far. I want him
+and I want Boylan. We're getting close to the end of the trail,
+Ned."
+
+"Yes, but we haven't found Mr. Damon yet, and his fortune seems to
+have vanished."
+
+"Well, we'll do the best we can," said Tom, grimly. "Now I'm going
+to get a warrant for the arrest of Peters, and one for Boylan, and
+I'm going to get myself appointed a special officer with power to
+serve them. We've got our work cut out for us, Ned."
+
+"Well, I'm with you to the end."
+
+"I know you are!" cried Tom.
+
+
+
+
+
+CHAPTER XXIV
+
+THE LONELY HOUSE
+
+
+The young inventor had little difficulty in getting the warrants
+he sought. In the case of Boylan, who seemed to be Peters's right-
+hand man, when it came to criminal work, Tom made a charge of
+unlawfully taking the airship. This would be enough to hold the
+man on until other evidence could be obtained against him.
+
+As for Peters, he was accused of taking certain valuable bonds and
+stocks belonging to Mr. Damon. Mrs. Damon gave the necessary
+evidence in this case, and the authorities were told that later,
+when Peters should have been arrested, other evidence so
+skillfully gotten by Tom's photo telephone, would be brought
+before the court.
+
+"It's a new way of convicting a man--by a photo telephone--but I
+guess it's a good one," said the judge who signed the warrants.
+
+"Well, now that we've got what we want, the next thing to do is to
+get the men--Peters, and the others," said Tom, as he and Ned sat
+in Tom's library after several hours of strenuous work.
+
+"How are you going to start?" the young banker wanted to know. "It
+seems a strange thing that a man like Mr. Damon could be made away
+with, and kept in hiding so long without something being heard of
+him. I'm afraid, Tom, that something must have happened to him."
+
+"I think so too, Ned. Nothing serious, though," Tom added,
+quickly, as he saw the look of alarm on his chum's face. "I think
+Mr. Damon at first went away of his own accord."
+
+"Of his own accord?"
+
+"Yes. I think Peters induced him to go with him, on the pretense
+that he could recover his fortune. After getting Mr. Damon in
+their power they kept him, probably to get the rest of his fortune
+away from him."
+
+"But you stopped that, Tom," said Ned, proud of his chum's
+abilities.
+
+"Well, I hope so," admitted the young inventor. "But I've still
+got plenty to do."
+
+"Have you a starting point?"
+
+"For one thing," Tom answered, "I'm going to have Mrs. Damon mail
+a fake package to the address Peters gave. If he, or any of his
+men, call for it, we'll have a detective on the watch, and arrest
+them."
+
+"Good!"
+
+"Of course it may not work," spoke Tom; "but it's something to
+try, and we can't miss any chances."
+
+Accordingly, the next day, a package containing only blank paper,
+made up to represent the documents demanded by Peters as the price
+of releasing Mr. Damon, was mailed to the address Mrs. Damon had
+received over the wire from the rascally promoter. Then a private
+detective was engaged to be on the watch, to take into custody
+whoever called for the bundle. Tom, though, had not much hope of
+anything coming of this, as it was evident that Peters had taken
+the alarm, and left.
+
+"And now," said Tom, when he had safely put away the wax record,
+containing the incriminating talk of Peters, and had printed
+several photographs, so wonderfully taken over the wire, "now to
+get on the trail again."
+
+It was not an easy one to follow. Tom began at the deserted home
+of the alleged financier. The establishment was broken up, for
+many tradesmen came with bills that had not been paid, and some of
+them levied on what little personal property there was to satisfy
+their claims. The servants left, sorrowful enough over their
+missing wages. The place was closed up under the sheriff's orders.
+
+But of Peters and his men not a trace could be found. Tom and Ned
+traveled all over the surrounding country, looking for clues, but
+in vain. They made several trips in the airship, but finally
+decided that an automobile was more practical for their work, and
+kept to that.
+
+They did find some traces of Peters. As Tom had said, the man was
+too prominent not to be noticed. He might have disguised himself,
+though it seemed that the promoter was a proud man, and liked to
+be seen in flashy clothes, a silk hat, and with a buttonhole
+bouquet.
+
+This made it easy to get the first trace of him. He had been seen
+to take a train at the Shopton station, though he had not bought a
+ticket. The promoter had paid his fare to Branchford, a junction
+point, but there all trace of him was lost. It was not even
+certain that he went there.
+
+"He may have done that to throw us off," said Tom. "Just because
+he paid his way to Branchford, doesn't say he went there. He may
+have gotten off at the next station beyond Shopton."
+
+"Do you think he's still lingering around here?" asked Ned.
+
+"I shouldn't be surprised," was Tom's answer. "He knows that there
+is still some of the Damon property left, and he is probably
+hungry for that. We'll get him yet, Ned."
+
+But at the end of several days Tom's hopes did not seem in a fair
+way to be realized. He and Ned followed one useless clue after
+another. All the trails seemed blind ones. But Tom never gave up.
+
+He was devoting all his time now to the finding of his friend Mr.
+Damon, and to the recovery of his fortune. In fact the latter was
+not so important to Tom as was the former. For Mrs. Damon was on
+the verge of a nervous collapse on account of the absence of her
+husband.
+
+"If I could only have some word from him, Tom!" she cried,
+helplessly.
+
+To Tom the matter was very puzzling. It seemed utterly impossible
+that Mr. Damon could be kept so close a prisoner that he could not
+manage to get some word to his friends. It was not as if he was a
+child. He was a man of more than ordinary abilities. Surely he
+might find a way to outwit his enemies.
+
+But the days passed, and no word came. A number of detectives had
+been employed, but they were no more successful than Tom. The
+latter had given up his inventive work, for the time being, to
+devote all his time to the solution of the mystery.
+
+Tom and Ned had been away from Shopton for three days, following
+the most promising clue they had yet received. But it had failed
+at the end, and one afternoon they found themselves in a small
+town, about a hundred miles from Shopton. They had been motoring.
+
+"I think I'll call up the house," said Tom. "Dad may have received
+some news, or Mrs. Damon may have sent him some word. I'll get my
+father on the wire."
+
+Connection to Tom's house was soon made, and Ned, who was
+listening to his chum's remarks, was startled to hear him cry out:
+
+"What's that you say? My airship taken again? When did it happen?
+Yes, I'm listening. Go on, Father!"
+
+Then followed a silence while Tom listened, breaking in now and
+then with an excited remark, Suddenly he called:
+
+"Good-by, Dad! I'm coming right home!"
+
+Tom hung up the receiver with a bang, and turned to his chum.
+
+"What do you think!" he cried. "The Eagle was taken again last
+night! The same way as before. Nobody got a glimpse of the
+thieves, though. Dad has been trying to get in communication with
+me ever since. I'm glad I called up. Now we'll get right back to
+Shopton, and see what we can do. This is the limit! Peters and his
+crowd will be kidnapping us, next."
+
+"That's right," agreed Ned.
+
+He and Tom were soon off again, speeding in the auto toward
+Shopton. But the roads were bad, after a heavy rain, and they did
+not make fast time.
+
+The coming of dusk found them with more than thirty miles to go.
+They were in an almost deserted section of the country when
+suddenly, as they were running slowly up a hill, there was a
+sudden crack, the auto gave a lurch to one side of the roadway and
+then settled heavily. Tom clapped on both brakes quickly, and gave
+a cry of dismay.
+
+"Broken front axle!" he said. "We're dished, Ned!"
+
+They got out, being no more harmed than by the jolting. The car
+was out of commission. The two chums looked around Except for a
+lonely house, that bore every mark of being deserted, not a
+dwelling was in sight where they might ask for aid or shelter.
+
+And, as they looked, from that lonely house came a strange cry--a
+cry as though for help!
+
+
+
+
+
+CHAPTER XXV
+
+THE AIRSHIP CAPTURE
+
+
+"Did you hear that?" cried Ned.
+
+"I certainly did," answered Tom. "What was it."
+
+"Sounded to me like a cry of some sort."
+
+"It was. An animal, I'd say."
+
+The two chums moved away from the broken auto, and looked at each
+other. Then, by a common impulse, they started toward the lonely
+house, which was set back some distance from the road.
+
+"Let's see who it was," suggested Tom, "After all, though it looks
+deserted, there may be someone in the house, and we've got to have
+some kind of help. I don't want to leave my car on the road all
+night, though it will have to be repaired before I can use it
+again."
+
+"It sure is a bad break," agreed Ned.
+
+As they walked toward the deserted House they heard the strange
+cry again. It was louder this time, and following it the boys
+heard a sound as if a blow had been struck.
+
+"Someone is being attacked!" cried Tom. "Maybe some poor tramp has
+taken shelter in there and a dog is after them. Come on, Ned,
+we've got to help!"
+
+They started on a run for the lonely house, but while still some
+distance away a curious thing happened.
+
+There was a sudden cry--an appeal for help it seemed--but this
+time in the open. And, as Tom and Ned looked, they saw several men
+running from the rear of the old house. Between them they carried
+an inert form,
+
+"Something's wrong!" exclaimed Tom, "There's crooked work going on
+here, Ned."
+
+"You're right! It's up to us to stop it! Come on!"
+
+But before the boys had taken half a dozen more steps they heard
+that which caused them great surprise. For from a shed behind the
+house came the unmistakable throb and roar of a motor.
+
+"They're going off in an auto!" cried Ned.
+
+"And they're carrying someone with them!" exclaimed Tom.
+
+By this time they had gotten to a point where they could see the
+shed, and what was their astonishment to see being rolled from it
+a big biplane. At the sight of it Tom cried:
+
+"It's the Eagle! That's my airship, Ned!"
+
+"You're right! How did it get here?"
+
+"That's for us to find out. I shouldn't wonder, Ned, but what
+we're at last on the trail of Peters and his crowd!"
+
+The men--there were four or five of them, Ned guessed--now broke
+into a run, still carrying among them the inert form of another.
+The cries for help had ceased, and it seemed as if the unfortunate
+one was unconscious.
+
+A moment later, and before the boys could do anything, had they
+the power, the men fairly jumped aboard Tom Swift's biggest
+airship. The unconscious one was carried with them.
+
+Then the motor was speeded up. The roar and throbbing were almost
+deafening.
+
+"Stop that! Hold on! That's my machine!" yelled Tom.
+
+He might as well have spoken to the wind. With a rush and a roar
+the big Eagle shot away and upward, carrying the men and their
+mysterious, unconscious companion. It was getting too dark for Tom
+and Ned to make out the forms or features of the strangers.
+
+"We're too late!" said Ned, hopelessly.
+
+"Yes, they got away," agreed Tom. "Oh, if only I had my speedy
+little monoplane!"
+
+"But who can they be? How did your airship get here? And who is
+that man they carried out of the house?" cried Ned.
+
+"I don't know the last--maybe one of their crowd who was injured
+in a fight."
+
+"What crowd?"
+
+"The Peters gang, of course. Can't you see it, Ned?"
+
+Unable to do anything, the two youths watched the flight of the
+Eagle. She did not move at her usual speed, for she was carrying
+too heavy a load.
+
+Presently from the air overhead, and slightly behind them, the
+boys heard the sound of another motor. They turned quickly.
+
+"Look!" cried Ned. "Another airship, by all that's wonderful!"
+
+"If we could only stop them!" exclaimed Tom. "That's a big
+machine, and they could take us aboard. Then we could chase the
+Eagle. We could catch her, too, for she's overloaded!"
+
+Frantically he and Tom waved their caps at the man who was now
+almost overhead in his airship. The boys did not call. They well
+knew, with the noise of the motor, the occupant of the airship
+could not hear them. But they waved and pointed to the slowly-
+moving Eagle.
+
+To their surprise and delight the man above them shut off his
+engine, and seemed about to come down. Then Tom cried, knowing he
+could be heard:
+
+"Help us capture that airship? It's mine and they've stolen it!"
+
+"All right! Be with you in a minute!" came back the answer from
+above.
+
+The second biplane came down to earth, ands as it ceased running
+along on its bicycle wheels, the occupant jumped out.
+
+"Hello, Tom Swift!" he called, as he took off his goggles.
+
+"Why--why it's Mr. Halling!" cried the young inventor, in delight,
+recognizing the birdman who had brought him the first news of Mr.
+Damon's trouble, the day the airship became entangled in the
+aerials of the wireless on Tom's house.
+
+"What are you doing here, Tom?" asked Mr. Hailing. "What has
+happened?"
+
+"We're looking for Mr. Damon. That's a bad crowd there," and he
+pointed toward the other aircraft. "They have my Eagle. Can you
+help me catch them?"
+
+"I certainly can--and will! Get aboard! I can carry four."
+
+"Then you have a new machine?"
+
+"Yes, and a dandy! All the latest improvements--self-starter and
+all! I'm glad of a chance to show it to you."
+
+"And I'm glad, too!" cried Tom. "It was providential that you
+happened along. What were you doing here?"
+
+"Just out on a trial spin. But come on, if we're going to catch
+those fellows!"
+
+Quickly Tom, Ned, and Mr. Halling climbed into the seats of the
+new airship. It was started from a switch, and in a few seconds it
+was on the wing, chasing after the Eagle.
+
+Then began a strange race, a race in the air after the unknown
+strangers who had Tom's machine. Had the Eagle not been so heavily
+laden it might have escaped, for Tom's craft was a speedy one. But
+this time it had to give the palm to Mr. Grant Halling's. Faster
+and faster in pursuit flew the Star, as the new craft was called.
+Faster and faster, until at last, coming directly over the Eagle,
+Mr. Halling sent his craft down in such a manner as to "blanket"
+the other. In an instant she began to sink, and with cries of
+alarm the men shut off the motor and started to volplane to the
+earth.
+
+But they made an unskillful landing. The Eagle tilted to one side,
+and came down with a crash. There were cries of pain, then
+silence, and a few seconds later two men ran away from the
+disabled airship. But there were three senseless forms on the
+ground beside the craft when Tom, Ned and Mr. Halling ran up. In
+the fading light Tom saw a face he knew--three faces in fact.
+
+"Mr. Damon!" he cried. "We've found him, Ned!"
+
+"But--too late--maybe!" answered Ned, in a low voice, as he, too,
+recognized the man who had been missing so long.
+
+Mr. Halling was bending over the unconscious form of his friend.
+
+"He's alive!" he cried, joyfully. "And not much hurt, either. But
+he has been ill, and looks half starved. Who are these men?"
+
+Tom gave a hasty look.
+
+"Shallock Peters and Harrison Boylan!" he cried. "Ned, at last
+we've caught the scoundrels!"
+
+It was true. Chance had played into the hands of Tom Swift. While
+Mr. Halling was looking after Mr. Damon, reviving him, the young
+inventor and Ned quickly bound the hands and feet of the two
+plotters with pieces of wire from the broken airship.
+
+Presently Mr. Damon opened his eyes.
+
+"Where am I? What happened? Oh, bless my watch chain--it's Tom
+Swift! Bless my cigar case, I--"
+
+"He's all right!" cried Tom, joyfully. "When Mr. Damon blesses
+something beside his tombstone he's all right."
+
+Peters and Boylan soon revived, both being merely stunned, as was
+Mr. Damon. They looked about in wonder, and then, feeling that
+they were prisoners, resigned themselves to their fate. Both men
+were shabbily dressed, and Tom would hardly have known the once
+spick and span Mr. Peters. He had no rose in his buttonhole now.
+
+"Well, you have me, I see," he said, coolly. "I was afraid we were
+playing for too high a stake."
+
+"Yes, we've got you," replied Tom,
+
+"But you can't prove much against me," went on Peters. "I'll deny
+everything."
+
+"We'll see about that," added the young inventor, grimly, and
+thought of the picture in the plate and the record on the wax
+cylinder.
+
+"We've got to get Mr. Damon to some place where he can be looked
+after," broke in Mr. Halling. "Then we'll hear the story."
+
+A passing farmer was prevailed on to take the party in his big
+wagon to the nearest town, Mr. Hailing going on ahead in his
+airship. Tom's craft could not be moved, being badly damaged.
+
+Once in town Peters and Boylan were put in jail, on the charges
+for which Tom carried warrants. Mr. Damon was taken to a hotel and
+a doctor summoned. It was as Mr. Halling had guessed. His friend
+had been ill, and so weak that he could not get out of bed. It was
+this that enabled the plotters to so easily keep him a prisoner.
+
+By degrees Mr. Damon told his story. He had rashly allowed Peters
+to get control of most of his fortune, and, in a vain hope of
+getting back some of his losses, had, one night--the night he
+disappeared, in fact--agreed to meet Peters and some of his men to
+talk matters over. Of this Mr. Damon said nothing to his wife.
+
+He went out that night to meet Peters in the garden, but the
+plotters had changed their plans. They boldly kidnapped their
+victim, chloroformed him and took him away in Tom's airship, which
+Boylan and some of his tools daringly stole a short time
+previously. Later they returned it, as they had no use for it at
+the lonely house.
+
+Mr. Damon was taken to the house, and there kept a prisoner. The
+men hoped to prevail on the fears of his wife to make her give up
+the valuable property. But we have seen how Tom foiled Peters.
+
+The experience of Mr. Damon, coupled with rough treatment he
+received, and lack of good food, soon made him ill. He was so weak
+that he could not help himself, and with that he was kept under
+guard. So he had no chance to escape or send his wife or friends
+any word.
+
+"But I'm all right now, Tom, thanks to you!" said he. "Bless my
+pocketbook, I don't care if my fortune is lost, as long as I'm
+alive and can get back to my wife."
+
+"But I don't believe your fortune will be lost," said Tom. "I
+think I have the picture and other evidence that will save it,"
+and he told of his photo telephone, and of what it had
+accomplished.
+
+"Bless my eyelashes!" cried Mr. Damon. "What a young man you are,
+Tom Swift!"
+
+Tom smiled gladly. He knew now that his old friend was himself
+once more.
+
+There is little left to tell. Chance had aided Tom in a most
+wonderful way--chance and the presence of Mr. Halling with his
+airship at just the right moment.
+
+Tom made a diligent effort to find out who it was that had
+chloroformed him in the telephone booth that time, but learned
+nothing definite. Peters and Boylan were both examined as to this
+on their trials, but denied it, and the young inventor was forced
+to conclude that it must have been some of the unscrupulous men
+who had taken his father's patent some time before.
+
+"They may have heard of your prosperity, and thought it a good
+chance to rob you," suggested Ned.
+
+"Maybe," agreed Tom. "Well, we'll let it go at that. Only I hope
+they don't come again."
+
+Mr. Damon was soon home with his wife again, and Peters and Boylan
+were held in heavy bail. They had secreted most of Mr. Damon's
+wealth, falsely telling him it was lost, and they were forced to
+give back his fortune. The evidence against them was clear and
+conclusive. When Tom went into court with his phonograph record of
+the talk of Peters, even though the man's voice was hoarse from a
+cold when he talked, and when his picture was shown, in the
+telephone booth, the jury at once convicted him.
+
+Boylan, when he learned of the missing button in Tom's possession,
+confessed that he and some of his men who were birdmen had taken
+Tom's airship. They wanted a means of getting Mr. Damon to the
+lonely house without being traced, and they accomplished it.
+
+As Tom had surmised, Peters had become suspicious after his last
+talk with Mrs. Damon, and had fled. He disguised himself and went
+into hiding with the others at the lonely house. Then he learned
+that the authorities of another city. where he had swindled many,
+were on his trail, and he decided to decamp with his gang, taking
+Mr. Damon with them. For this purpose Tom's airship was taken the
+second time, and a wholesale escape, with Mr. Damon a prisoner,
+was planned.
+
+But fate was against the plotters. Two of them did manage to get
+away, but they were not really wanted. The big fish were Peters
+and Boylan, and they were securely caught in the net of the law.
+Peters was greatly surprised when he learned of Tom's trap, and of
+the photo telephone. He had no idea he had been incriminating
+himself when he talked over the wire.
+
+"Well, it's all over," remarked Ned to Tom, one day, when the
+disabled auto and the airship had been brought home and repaired.
+"The plotters are in prison for long terms, and Mr. Damon is
+found, together with his fortune. The photo telephone did it,
+Tom."
+
+"Not all of it--but a good bit," admitted the young inventor, with
+a smile.
+
+"What are you going to do next, Tom?"
+
+"I hardly know. I think--"
+
+Before Tom could finish, a voice was heard in the hall outside the
+library.
+
+"Bless my overshoes! Where's Tom? I want to thank him again for
+what he did for me," and Mr. Damon, now fully recovered, came in.
+"Bless my suspender button, but it's good to be alive, Tom!" he
+cried.
+
+"It certainly is," agreed Tom. "And the next time you go for a
+conference with such men as Peters, look out for airships."
+
+"I will, Tom, I will!" exclaimed Mr. Damon. "Bless my watch chain,
+I will!"
+
+And now, for a time, we will say good-bye to Tom Swift, leaving
+him to perfect his other inventions.

+
+<P>
+"Tom, I don't believe it can be done!"
+
+<P>
+"But, Dad, I'm sure it can!"
+
+<P>
+Tom Swift looked over at his father, who was seated in an easy
+chair in the library. The elderly gentleman--his hair was quite
+white now--slowly shook his head, as he murmured again:
+
+<P>
+"It can't be done, Tom! It can't be done! I admit that you've made
+a lot of wonderful things--things I never dreamed of--but this is
+too much. To transmit pictures over a telephone wire, so that
+persons cannot only see to whom they are talking, as well as hear
+them--well, to be frank with you, Tom, I should be sorry to see
+you waste your time trying to invent such a thing."
+
+<P>
+"I don't agree with you. Not only do I think it can be done, but
+I'm going to do it. In fact, I've already started on it. As for
+wasting my time, well, I haven't anything in particular to do, now
+that my giant cannon has been perfected, so I might as well be
+working on my new photo telephone instead of sitting around idle."
+
+<P>
+"Yes, Tom, I agree with you there," said Mr. Swift. "Sitting
+around idle isn't good for anyone--man or boy, young or old. So
+don't think I'm finding fault because you're busy."
+
+<P>
+"It's only that I don't want to see you throw away your efforts,
+only to be disappointed in the end. It can't be done, Tom, it
+can't be done," and the aged inventor shook his head in pitying
+doubt.
+
+<P>
+Tom only smiled confidently, and went on:
+
+<P>
+"Well, Dad, all you'll have to do will be to wait and see. It
+isn't going to be easy--I grant that. In fact, I've run up against
+more snags, the little way I've gone so far, than I like to admit.
+But I'm going to stick at it, and before this year is out I'll
+guarantee, Father, that you can be at one end of the telephone
+wire, talking to me, at the other, and I'll see you and you'll see
+me--if not as plainly as we see each other now, at least plainly
+enough to make sure of each other."
+
+<P>
+Mr. Swift chuckled silently, gradually breaking into a louder
+laugh. Instead of being angry, Tom only regarded his father with
+an indulgent smile, and continued:
+
+<P>
+"All right, Dad. Go ahead, laugh!"
+
+<P>
+"Well, Tom, I'm not exactly laughing at <i>you</i>--it's more at the
+idea than anything else. The idea of talking over a wire and, at
+the same time, having light waves, as well as electrical waves
+passing on the same conductor!"
+
+<P>
+"All right, Dad, go ahead and laugh. I don't mind," said Tom,
+good-naturedly. "Folks laughed at Bell, when he said he could send
+a human voice over a copper spring; but Bell went ahead and to-day
+we can talk over a thousand miles by wire. That was the telephone."
+
+<P>
+"Folks laughed at Morse when he said he could send a message over the
+wire. He let 'em laugh, but we have the telegraph. Folks laughed at
+Edison, when he said he could take the human voice--or any other
+sound--and fix it on a wax cylinder or a hard-rubber plate--but he did
+it, and we have the phonograph. And folks laughed at Santos Dumont, at
+the Wrights, and at all the other fellows, who said they could take a
+heavier-than-air machine, and skim above the clouds like a bird; but
+we do it--I've done it--you've done it."
+
+<P>
+"Hold on, Tom!" protested Mr. Swift. "I give up! Don't rub it in
+on your old dad. I admit that folks did laugh at those inventors,
+with their seemingly impossible schemes, but they made good. And
+you've made good lots of times where I thought you wouldn't. But
+just stop to consider for a moment. This thing of sending a
+picture over a telephone wire is totally out of the question, and
+entirely opposed to all the principles of science."
+
+<P>
+"What do I care for principles of science?" cried Tom, and he
+strode about the room so rapidly that Eradicate, the old colored
+servant, who came in with the mail, skipped out of the library
+with the remark:
+
+<P>
+"Deed, an' Massa Tom must be pow'fully preragitated dis mawnin'!"
+
+<P>
+"Some of the scientists said it was totally opposed to all natural
+laws when I planned my electric rifle," went on Tom. "But I made
+it, and it shot. They said my air glider would never stay up, but
+she did."
+
+<P>
+"But, Tom, this is different. You are talking of sending light
+waves--one of the most delicate forms of motion in the world--over
+a material wire. It can't be done!"
+
+<P>
+"Look here, Dad!" exclaimed Tom, coming to a halt in front of his
+parent. "What is light, anyhow? Merely another form of motion;
+isn't it?"
+
+<P>
+"Well, yes, Tom, I suppose it is."
+
+<P>
+"Of course it is," said Tom. "With vibrations of a certain length
+and rapidity we get sound--the faster the vibration per second the
+higher the sound note. Now, then, we have sound waves, or
+vibrations, traveling at the rate of a mile in a little less than
+five seconds; that is, with the air at a temperature of sixty
+degrees. With each increase of a degree of temperature we get an
+increase of about a foot per second in the rapidity with which
+sound travels."
+
+<P>
+"Now, then, light shoots along at the rate of 186,000,000 miles a
+second. That is more than many times around the earth in a second
+of time. So we have sound, one kind of wave motion, or energy; we
+have light, a higher degree of vibration or wave motion, and then
+we come to electricity--and nobody has ever yet exactly measured
+the intensity or speed of the electric vibrations."
+
+<P>
+"But what I'm getting at is this--that electricity must travel
+pretty nearly as fast as light--if not faster. So I believe that
+electricity and light have about the same kind of vibrations, or
+wave motion."
+
+<P>
+"Now, then, if they do have--and I admit it's up to me to prove
+it," went on Tom, earnestly--"why can't I send light-waves over a
+wire, as well as electrical waves?"
+
+<P>
+Mr. Swift was silent for a moment. Then he said, slowly:
+
+<P>
+"Well, Tom, I never heard it argued just that way before. Maybe
+there's something in your photo telephone after all. But it never
+has been done. You can't deny that!"
+
+<P>
+He looked at his son triumphantly. It was not because he wanted to
+get the better of him in argument, that Mr. Swift held to his own
+views; but he wanted to bring out the best that was in his
+offspring. Tom accepted the challenge instantly.
+
+<P>
+"Yes, Dad, it has been done, in a way!" he said, earnestly. "No
+one has sent a picture over a telephone wire, as far as I know,
+but during the recent hydroplane tests at Monte Carlo, photographs
+taken of some of the events in the morning, and afternoon, were
+developed in the evening, and transmitted over five hundred miles
+of wire to Paris, and those same photographs were published in the
+Paris newspapers the next morning."
+
+<P>
+"Is that right, Tom?"
+
+<P>
+"It certainly is. The photographs weren't so very clear, but you
+could make out what they were. Of course that is a different
+system than the one I'm thinking of. In that case they took a
+photograph, and made a copper plate of it, as they would for a
+half-tone illustration. This gave them a picture with ridges and
+depressions in copper, little hills and valleys, so to speak,
+according to whether there were light or dark tints in the
+picture. The dark places meant that the copper lines stood up
+higher there than where there were light colors."
+
+<P>
+"Now, by putting this copper plate on a wooden drum, and revolving
+this drum, with an electrical needle pressing lightly on the
+ridges of copper, they got a varying degree of electrical current.
+Where the needle touched a high place in the copper plate the
+contact was good, and there was a strong current. When the needle
+got to a light place in the copper--a depression, so to speak--the
+contact was not so good, and there was only a weak current."
+
+<P>
+"At the receiving end of the apparatus there was a sensitized film
+placed on a similar wooden drum. This was to receive the image
+that came over the five hundred miles of wire. Now then, as the
+electrical needle, moving across the copper plate, made electrical
+contacts of different degrees of strength, it worked a delicate
+galvanometer on the receiving end. The galvanometer caused a beam
+of light to vary--to grow brighter or dimmer, according as the
+electrical current was stronger or weaker. And this light, falling
+on the sensitive plate, made a picture, just like the one on the
+copper plate in Monte Carlo."
+
+<P>
+"In other words, where the copper plate was black, showing that
+considerable printing ink was needed, the negative on the other
+end was made light. Then when that negative was printed it would
+come out black, because more light comes through the light places
+on a photograph negative than through the dark places. And so,
+with the galvanometer making light flashes on the sensitive plate,
+the galvanometer being governed by the electrical contacts five
+hundred miles away, they transmitted a photograph by wire."
+
+<P>
+"But not a telephone wire, Tom."
+
+<P>
+"That doesn't make any difference, Dad. It was a wire just the
+same. But I'm not going into that just now, though later I may
+want to send photographs by wire. What I'm aiming at is to make an
+apparatus so that when you go into a telephone booth to talk to a
+friend, you can see him and he can see you, on a specially
+prepared plate that will be attached to the telephone."
+
+<P>
+"You mean see him as in a looking-glass, Tom?"
+
+<P>
+"Somewhat, yes. Though I shall probably use a metal plate instead
+of glass. It will be just as if you were talking over a telephone
+in an open field, where you could see the other party and he could
+see you."
+
+<P>
+"But how are you going to do it, Tom?"
+
+<P>
+"Well, I haven't quite decided. I shall probably have to use the
+metal called selenium, which is very sensitive to light, and which
+makes a good or a poor electrical conductor according as more or
+less light falls on it. After all, a photograph is only lights and
+shadows, fixed on sensitive paper or films."
+
+<P>
+"Well, Tom, maybe you can do it, and maybe you can't. I admit
+you've used some good arguments," said Mr. Swift. "But then, it
+all comes down to this: What good will it be if you can succeed in
+sending a picture over a telephone wire?"
+
+<P>
+"What good, Dad? Why, lots of good. Just think how important it
+will be in business, if you can make sure that you are talking to
+the party you think you are. As it is now, unless you know the
+person's voice, you can't tell that the man on the other end of
+the wire is the person he says he is. And even a voice can be
+imitated."
+
+<P>
+"But if you know the person yourself, he can't be imitated. If you
+see him, as well as hear his voice, you are sure of what you are
+doing. Why, think of the big business deals that could be made
+over the telephone if the two parties could not only hear but see
+each other. It would be a dead sure thing then. And Mr. Brown
+wouldn't have to take Mr. Smith's word that it was he who was
+talking. He could even get witnesses to look at the wire-image if
+he wanted to, and so clinch the thing. It will prevent a lot of
+frauds."
+
+<P>
+"Well, Tom, maybe you're right. Go ahead. I'll say no more against
+your plans. I wish you all success, and if I can help you, call on
+me."
+
+<P>
+"Thanks, Dad. I knew you'd feel that way when you understood. Now
+I'm going--"
+
+<P>
+But what Tom Swift was going to do he did not say just then, for
+above the heads of father and son sounded a rattling, crashing
+noise, and the whole house seemed to shake Then the voice of
+Eradicate was heard yelling:
+
+<P>
+"Good land! Good land ob massy! Come out yeah, Massa Tom! Come
+right out yeah! Dere's a man on de roof an' he am all tangled up
+suthin' scandalous! Come right out yeah befo' he falls and
+translocates his neck! Come on!"
+
+
+

+<H3>Chapter II Bad News</H3>
+
+
+<P>
+With startled glances at each other, Tom and his father rushed
+from the library to the side of the house, whence came the cries
+of Eradicate.
+
+<P>
+"What is it, Rad! what is it?" questioned Tom.
+
+<P>
+"Is someone hurt?" Mr. Swift wanted to know.
+
+<P>
+"He mighty soon will be!" exclaimed the colored man. "Look where
+he am holdin' on! Lucky fo' him he grabbed dat chimbley!"
+
+<P>
+Tom and his father looked to where Eradicate pointed, and saw a
+strange sight. A small biplane-airship had become entangled in
+some of the aerials of Tom's wireless apparatus, and the craft had
+turned turtle, being held from falling by some of the wire braces.
+
+<P>
+The birdman had fallen out, but had managed to cling to the
+chimney, so that he had not reached the ground, and there he
+clung, while the motor of his airship was banging away, and
+revolving the propeller blades dangerously close to his head.
+
+<P>
+"Are you hurt?" cried Tom, to the unknown birdman.
+
+<P>
+"No, but I'm likely to be unless I get out of here!" was the
+gasped-out answer.
+
+<P>
+"Hold fast!" cried Tom. "We'll have you down in a jiffy. Here,
+Rad, you get the long ladder. Where's Koku? That giant is never
+around when he's wanted. Find Koku, Rad, and send him here."
+
+<P>
+"Yas, sah, Massa Tom; directly, sah!" and the colored man hastened
+off as fast as his aged legs would take him.
+
+<P>
+And while preparations are thus under way to rescue the birdman
+from the roof, I will take just a few minutes to tell you a little
+something more about Tom Swift and his numerous inventions, as set
+forth in the previous books of this series.
+
+<P>
+"Tom Swift and His Motor Cycle" was the first book, and in that I
+related how Tom made the acquaintance of a Mr. Wakefield Damon, of
+the neighboring town of Waterford, and how Tom bought that
+gentleman's motor cycle, after it had tried to climb a tree with
+its rider in the saddle. Mr. Wakefield Damon was an odd man, whose
+favorite expression was "Bless my shoelaces!" or something equally
+absurd. Waterford was not far from Shopton, where Tom and his
+father made their home.
+
+<P>
+Mr. Swift was also an inventor of note, and Tom soon followed in
+his father's footsteps. They lived in a large house, with many
+shops about it, for their work at times required much machinery.
+
+<P>
+Mrs. Baggert was the housekeeper who looked after Tom and his
+father, and got their meals, when they consented to take enough
+time from their inventive work to eat. Another member of the
+household was Eradicate Sampson, a genial old colored man, who
+said he was named Eradicate because he used to eradicate the dirt
+about the place.
+
+<P>
+Koku, just referred to by Tom, was an immense man, a veritable
+giant, whom Tom had brought back with him from one of his trips,
+after escaping from captivity. The young inventor really brought
+two giants, brothers they were, but one had gone to a museum, and
+the other took service with our hero, making himself very useful
+when it came to lifting heavy machinery.
+
+<P>
+Tom had a close friend in Ned Newton, who was employed in the
+Shopton bank. Another friend was Miss Mary Nestor, a young lady
+whose life Tom had once saved. He had many other friends, and some
+enemies, whom you will meet from time to time in this story.
+
+<P>
+After Tom had had many adventures on his motor cycle he acquired a
+motor boat, and in that he and Ned went through some strenuous
+times on Lake Carlopa, near Tom's home. Then followed an airship,
+for Tom got that craze, and in the book concerning that machine I
+related some of the things that happened to him. He had even more
+wonderful adventures in his submarine, and with his electric
+runabout our hero was instrumental in saving a bank from ruin by
+making a trip in the speediest car on the road.
+
+<P>
+After Tom Swift had sent his wireless message, and saved the
+castaways of Earthquake Island, he thought he would give up his
+inventive work for a time, and settle down to a life of ease and
+quiet.
+
+<P>
+But the call of the spirit of adventure was still too strong for
+him to resist. That was why he sought out the diamond makers, and
+learned the secret of Phantom Mountain. And when he went to the
+Caves of Ice, and there saw his airship wrecked, Tom was well-nigh
+discouraged, But he managed to get back to civilization, and later
+undertook a journey to elephant land, with his powerful electric
+rifle.
+
+<P>
+Marvelous adventures underground did Tom Swift have when he went
+to the City of Gold, and I have set down some of them in the book
+bearing the latter title. Later on he sought the platinum treasure
+in his air glider. And when Tom was taken captive, in giant land,
+only his speedy airship saved him from a hard fate.
+
+<P>
+By this time moving pictures were beginning to occupy a large
+place in the scientific, as well as the amusement world, and Tom
+invented a Wizard Camera which did excellent work. Then came the
+need of a powerful light, to enable Uncle Sam's custom officers on
+the border to detect the smugglers, and Tom was successful in
+making his apparatus.
+
+<P>
+He thought he would take a rest after that, but with the opening
+of the Panama Canal came the need of powerful guns to protect that
+important waterway, and Tom made a Giant Cannon, which enabled the
+longest shots on record to be fired.
+
+<P>
+Now, some months had passed, after the successful trial of the big
+weapon, and Tom longed for new activities. He found them in the
+idea of a photo telephone, and he and his father were just talking
+of this when interrupted by the accident to the birdman on the
+roof of the Swift home.
+
+<P>
+"Have you got that ladder, Rad?" cried the young inventor,
+anxiously, as he saw the dangerous position of the man from the
+airship.
+
+<P>
+"Yas, sah, Massa Tom! I'se a-camin' wif it!"
+
+<P>
+"And where's Koku? We'll need him!"
+
+<P>
+"He's a-camin', too!"
+
+<P>
+"Here Koku!" exclaimed a deep voice, and a big man came running
+around the corner of the house. "What is it, Master?"
+
+<P>
+"We must get him down, Koku!" said Tom, simply. "I will go up on
+the roof. You had better come, too. Rad, go in the house and get a
+mattress from the bed. Put it down on the ground where he's likely
+to fall. Lively now!"
+
+<P>
+"Yas, sah, Massa Tom!"
+
+<P>
+"Me git my own ladder--dat one not strong 'nuff!" grunted Koku,
+who did not speak very good English. He had a very strong ladder,
+of his own make, built to hold his enormous bulk, and this he soon
+brought and placed against the side of the house.
+
+<P>
+Meanwhile Tom and his father had raised the one Eradicate had
+brought, though Tom did most of the lifting, for his father was
+elderly, and had once suffered from heart trouble.
+
+<P>
+"We're coming for you!" cried the young inventor as he began to
+ascend the ladder, at the same time observing that the giant was
+coming with his. "Can you hold on a little longer?"
+
+<P>
+"Yes, I guess so. But I dare not move for fear the propellers will
+strike me."
+
+<P>
+"I see. I'll soon shut off the motor," said Tom. "What happened,
+anyhow?"
+
+<P>
+"Well, I was flying over your house. I was on my way to pay you a
+visit, but I didn't intend to do it in just this way," and the
+birdman smiled grimly. "I didn't see your wireless aerials until I
+was plumb into them, and then it was too late. I hope I haven't
+damaged them any."
+
+<P>
+"Oh, they are easily fixed," said Tom. "I hope you and your
+biplane are not damaged. This way, Koku!" he called to the giant.
+
+<P>
+"Say, is--is he real, or am I seeing things?" asked the aviator,
+as he looked at the big man.
+
+<P>
+"Oh, he's real, all right," laughed Tom. "Now, then, I'm going to
+shut off your motor, and then you can quit hugging that chimney,
+and come down."
+
+<P>
+"I'll be real glad to," said the birdman.
+
+<P>
+Making his way cautiously along the gutters of the roof, Tom
+managed to reach the motor controls. He pulled out the electrical
+switch, and with a sort of cough and groan the motor stopped. The
+big propellers ceased revolving, and the aviator could leave his
+perch in safety.
+
+<P>
+This he did, edging along until he could climb down and meet Tom,
+who stood near the ladder.
+
+<P>
+"Much obliged," said the birdman, as he shook hands with Tom. "My
+name is Grant Halling. I'm a newcomer in Mansburg," he added,
+naming a town not far from Shopton. "I know you by reputation, so
+you don't need to introduce yourself."
+
+<P>
+"Glad to meet you," said the young inventor, cordially. "Rather a
+queer place to meet a friend," he went on with a laugh and a
+glance down to the ground. "Can you climb?"
+
+<P>
+"Oh, yes, I'm used to that. The next thing will be to get my
+machine down."
+
+<P>
+"Oh, we can manage that with Koku's help," spoke Tom. "Koku, get
+some ropes, and see what you and Rad can do toward getting the
+aeroplane down," he added to the giant. "Let me know if you need
+any help."
+
+<P>
+"Me can do!" exclaimed the big man. "Me fix him!"
+
+<P>
+Tom and Mr. Halling made their way down the ladder, while the
+giant proceeded to study out a plan for getting the airship off
+the roof.
+
+<P>
+"You say you were coming over to see me, when you ran into my
+wireless aerials?" asked Tom, curiously, when he had introduced
+his father to the birdman.
+
+<P>
+"Yes," went on Mr. Halling. "I have been having some trouble with
+my motor, and I thought perhaps you could tell me what was wrong.
+My friend, Mr. Wakefield Damon, sent me to you."
+
+<P>
+"What! Do you know Mr. Damon?" cried Tom.
+
+<P>
+"I've known' him for some years. I met him in the West, but I
+hadn't seen him lately, until I came East. He sent me to see you,
+and said you would help me."
+
+<P>
+"Well, any friend of Mr. Damon's is a friend of mine!" exclaimed
+Tom, genially. "I'll have a look at your machine as soon as Koku
+gets it down. How is Mr. Damon, anyhow? I haven't seen him in over
+two weeks."
+
+<P>
+"I'm sorry to say he isn't very well, Mr. Swift."
+
+<P>
+"Is he ill? What is the trouble?"
+
+<P>
+"He isn't exactly ill," went on Mr. Halling, "but he is fretting
+himself into a sickness, worrying over his lost fortune."
+
+<P>
+"His lost fortune!" cried Tom, in surprise at the bad news
+concerning his friend. "I didn't know he had lost his money!"
+
+<P>
+"He hasn't yet, but he's in a fair way to, he says. It's something
+about bad investments, and he did speak of the trickery of one
+man, I didn't get the particulars. But he certainly feels very
+badly over it."
+
+<P>
+"I should think he would," put in Mr. Swift. "Tom, we must look
+into this. If we can help Mr. Damon--"
+
+<P>
+"We certainly will," interrupted Tom. "Now come in the house, Mr.
+Halling. I'm sure you must be quite shaken up by your upset."
+
+<P>
+"I am, to tell you the truth, though it isn't the first accident
+I've had in my airship."
+
+<P>
+They were proceeding toward the house, when there came a cry from
+Koku, who had fastened a rope about the airship to lower it.
+
+<P>
+"Master! Master!" cried the giant. "The rope am slippin'. Grab the
+end of it!"
+
+
+
+
+
+<P>
+<A NAME="III"></A>
+<H3>Chapter III Tom's Failure</H3>
+
+
+<P>
+"Come on!" cried Tom, quickly, as, turning', he saw the accident
+about to happen. "Your craft will surely be smashed if she slips
+to the ground, Mr. Halling!"
+
+<P>
+"You're right! This seems to be my unlucky day!" The birdman,
+limping slightly from his fall, hurried with Tom to where a rope
+trailed on the ground. Koku had fastened one end to the airship,
+and had taken a turn of the cable about the chimney. He had been
+lowering the biplane to the ground, but he had not allowed for its
+great weight, and the rope had slipped from his big hands.
+
+<P>
+But Tom and Mr. Halling were just in time. They grabbed the
+slipping hempen strands, and thus checked the falling craft until
+Koku could get a better grip.
+
+<P>
+"All right now," said the giant, when he had made fast the rope.
+"Me fix now. Master can go."
+
+<P>
+"Think he can lower it?" asked Mr. Halling, doubtfully.
+
+<P>
+"Oh, surely," said Tom. "Koku's as strong as a horse. You needn't
+worry. He'll get it down all right. But you are limping."
+
+<P>
+"Yes, I jammed my leg a little."
+
+<P>
+"Don't you want a doctor?"
+
+<P>
+"Oh, no, not for a little thing like that."
+
+<P>
+But Tom insisted on looking at his new friend's wound, and found
+quite a cut on the thigh, which the young inventor insisted on
+binding up.
+
+<P>
+"That feels better," said the birdman, as he stretched out on a
+couch. "Now if you can look my machine over, and tell me what's
+the matter with it, I'll be much obliged to you, and I'll get on
+my way."
+
+<P>
+"Not quite so fast as that!" laughed Tom. "I wouldn't want to see
+you start off with your lame leg, and certainly I would not want
+to see you use your aircraft after what she's gone through, until
+we've given her a test. You can't tell what part you might have
+strained."
+
+<P>
+"Well, I suppose you are right. But I think I'd better go to a
+hotel, or send for an auto and go home."
+
+<P>
+"Now you needn't do anything of the kind," spoke Tom, hospitably.
+"We've got lots of room here, and for that matter we have plenty
+of autos and airships, too, as well as a motor boat. You just rest
+yourself here. Later we'll look over your craft."
+
+<P>
+After dinner, when Mr. Halling said he felt much better, Tom
+agreed to go out with him and look at the airship. As he feared,
+he found several things the matter with it, in addition to the
+motor trouble which had been the cause for Mr. Halling's call on
+the young inventor.
+
+<P>
+"Can she be fixed?" asked the birdman, who explained that, as yet,
+he was only an amateur in the practice of flying.
+
+<P>
+"Oh, yes, we can fix her up for you," said Tom. "But it will take
+several days. You'll have to leave it here."
+
+<P>
+"Well, I'll be glad to do that, for I know she will be all the
+better when you get through with her. But I think I am able to go
+on home now, and I really ought to. There is some business I must
+attend to."
+
+<P>
+"Speaking of business," remarked Tom, "can you tell me anything
+more of Mr. Damon's financial troubles?"
+
+<P>
+"No, not much. All I know is that when I called on him the other
+day I found him with his check book out, and he was doing a lot of
+figuring. He looked pretty blue and downcast, I can tell you."
+
+<P>
+"I'm sorry about that," spoke Tom, musingly. "Mr. Damon is a very
+good friend of mine, and I'd do anything to help him. I certainly
+wouldn't like to see him lose his fortune. Bad investments, you
+say it was?"
+
+<P>
+"Partly so, and yet I'm inclined to think if he does lose his
+money it will be due to some trickery. Mr. Damon is not the man to
+make bad investments by himself."
+
+<P>
+"Indeed he is not," agreed Tom. "You say he spoke of some man?"
+
+<P>
+"Yes, but not definitely. He did not mention any name. But Mr.
+Damon was certainly quite blue."
+
+<P>
+"That's unlike him," remarked Tom. "He is usually very jolly. He
+must be feeling quite badly. I'll go over and have a talk with
+him, as soon as I can."
+
+<P>
+"Do. I think he would appreciate it. And now I must see about
+getting home."
+
+<P>
+"I'll take you in one of my cars," said Tom, who had several
+automobiles. "I don't want to see you strain that injured leg of
+yours."
+
+<P>
+"You're very good--especially after I tangled up your wireless
+aerials; but I didn't see them until I was right into them,"
+apologized Mr. Halling.
+
+<P>
+"They're a new kind of wire," said Tom, "and are not very plain to
+see. I must put up some warning signs. But don't worry about
+damaging them. They were only up temporarily anyhow, and I was
+going to take them down to arrange for my photo telephone."
+
+<P>
+"Photo telephone, eh? Is that something new?"
+
+<P>
+"It will be--if I can get it working," said Tom, with a smile.
+
+<P>
+A little later Tom had taken Mr. Halling home, and then he set
+about making arrangements for repairing the damaged airship. This
+took him the better part of a week, but he did not regret the
+time, for while he was working he was busy making plans for his
+newest invention--the photo telephone.
+
+<P>
+One afternoon, when Tom had completed the repairs to the airship,
+and had spent some time setting up an experimental telephone line,
+the young inventor received a call from his chum, Ned Newton.
+
+<P>
+"Well, well, what are you up to now?" asked Ned, as he saw his
+chum seated in a booth, with a telephone receiver to his ear,
+meanwhile looking steadily at a polished metal plate in front of
+him. "Trying to hypnotize yourself, Tom?"
+
+<P>
+"Not exactly. Quiet, Ned, please. I'm trying to listen."
+
+<P>
+Ned was too familiar with his chum's work to take offense at this.
+The young banker took a seat on a box, and silently watched Tom.
+The inventor shifted several switches, pressed one button after
+another, and tilted the polished metal plate at different angles.
+Then he closed the door of the little telephone booth, and Ned,
+through the ground glass door, saw a light shining.
+
+<P>
+"I wonder what new game Tom is up to?" Ned mused.
+
+<P>
+Presently the door opened, and Tom stuck out his head.
+
+<P>
+"Ned, come here," he invited. "Look at that metal plate and see if
+you can notice anything on it. I've been staring at it so steadily
+that my eyes are full of sticks. See what you can make out."
+
+<P>
+"What is this?" asked Ned. "No trick; is it? I won't be blown up,
+or get my eyes full of pepper; will I?"
+
+<P>
+"Nonsense! Of course not. I'm trying to make a photo telephone. I
+have the telephone part down pat, but I can't see anything of the
+photo image. See if you can."
+
+<P>
+Ned stared at the polished plate, while Tom did things to it,
+making electrical connections, and tilting it at various angles.
+
+<P>
+"See anything, Ned?" asked Tom.
+
+<P>
+The other shook his head.
+
+<P>
+"Whom am I supposed to see?" he asked.
+
+<P>
+"Why, Koku is at the other end of the wire. I'm having him help
+me."
+
+<P>
+Ned gazed from the polished plate out of a side window of the
+shop, into the yard.
+
+<P>
+"Well, that Koku is certainly a wonderful giant," said Ned, with a
+laugh.
+
+<P>
+"How so?" asked Tom.
+
+<P>
+"Why he can not be in two places at once. You say he ought to be
+at the other end of this wire, and there he is out there, spading
+up the garden."
+
+<P>
+Tom stared for a second and then exclaimed:
+
+<P>
+"Well, if that isn't the limit! I put him in the telephone booth
+in the machine shop, and told him to stay there until I was
+through. What in the world is he doing out there?"
+
+<P>
+"Koku!" he called to the giant, "why didn't you stay at the
+telephone where I put you? Why did you run away?"
+
+<P>
+"Ha!" exclaimed the giant, who, for all his great size was a
+simple chap, "little thing go 'tick-tick' and then 'clap-clap!'
+Koku no like--Koku t'ink bad spirit in telumfoam--Koku come out!"
+
+<P>
+"Well, no wonder I couldn't see any image on the plate!" exclaimed
+Tom. "There was nobody there. Now, Ned, you try it; will you,
+please?"
+
+<P>
+"Sure. Anything to oblige!"
+
+<P>
+"Then go in the other telephone booth. You can talk to me on the
+wire. Say anything you like--the telephone part is all right. Then
+you just stand so that the light in the booth shines on your face.
+The machine will do the rest--if it works."
+
+<P>
+Ned hurried off and was soon talking to his chum over the wire
+from the branch telephone in the machine shop. Ned stood in the
+glare of an electric light, and looked at a polished plate similar
+to the one in the other booth.
+
+<P>
+"Are you there, Ned?" asked Tom.
+
+<P>
+"Yes, I'm here."
+
+<P>
+"Is the light on?"
+
+<P>
+"Yes."
+
+<P>
+"And you're looking at the plate?"
+
+<P>
+"Sure. Can you see any reflection in your plate?"
+
+<P>
+"No, not a thing," answered Tom, and there was great
+discouragement in his voice. "The thing is a failure, Ned. Come on
+back," and the young banker could hear his chum hang up the
+telephone receiver at the other end.
+
+<P>
+"That's too bad," murmured Ned, knowing how Tom must feel. "I'll
+have to cheer him up a bit."
+
+
+
+
+
+<P>
+<A NAME="IV"></A>
+<H3>Chapter IV Run Down</H3>
+
+
+<P>
+When Ned Newton got back to where Tom sat in the small telephone
+booth, the young banker found his chum staring rather moodily at
+the polished metal plate on the shelf that held the talking
+instrument.
+
+<P>
+"So it was no go; eh, Tom?"
+
+<P>
+"No go at all, Ned, and I thought sure I had it right this time."
+
+<P>
+"Then this isn't your first experiment?"
+
+<P>
+"Land no! I've been at it, off and on, for over a month, and I
+can't seem to get any farther. I'm up against a snag now, good and
+hard."
+
+<P>
+"Then there wasn't any image on your plate?"
+
+<P>
+"Not a thing, Ned. I don't suppose you caught any glimpse of me in
+your plate?" asked Tom, half hopefully.
+
+<P>
+"No. I couldn't see a thing. So you are going to try and make this
+thing work both ways, are you?"
+
+<P>
+"That's my intention, But I can fix it so that a person can
+control the apparatus at his end, and only see the person he is
+talking to, not being seen himself, unless he wishes it. That is,
+I hope to do that. Just now nobody can see anybody," and Tom
+sighed.
+
+<P>
+"Give it up," advised Ned. "It's too hard a nut to crack, Tom!"
+
+<P>
+"Indeed, I'll not give it up, Ned! I'm going to work along a new
+line. I must try a different solution of selenium on the metal
+plate. Perhaps I may have to try using a sensitized plate, and
+develop it later, though I do want to get the machine down so you
+can see a perfect image without the need of developing. And I
+will, too!" cried Tom. "I'll get some new selenium."
+
+<P>
+Eradicate, who came into the shop just then, heard the end of
+Tom's remarks. A strange look came over his honest black face, and
+he exclaimed:
+
+<P>
+"What all am dat, Massa Tom? Yo'ah gwine t' bring de new millenium
+heah? Dat's de end of de world, ain't it-dat millenium? Golly!
+Dish yeah coon neber 'spected t' lib t' see dat. De millenium! Oh
+mah landy!"
+
+<P>
+"No, Rad!" laughed Tom. "I was speaking about selenium, a sort of
+metallic combination that is a peculiar conductor of electricity.
+The more light that shines on it the better conductor it is, and
+the less light, the poorer."
+
+<P>
+"It must be queer stuff," said Ned.
+
+<P>
+"It is," declared Tom. "I think it is the only thing to use in
+this photo telephone experiment, though I might try the metal
+plate method, as they did between Monte Carlo and Paris. But I am
+not trying to make newspaper pictures."
+
+<P>
+"What is selenium, anyhow?" asked Ned. "Remember, Tom, I'm not up
+on this scientific stuff as you are."
+
+<P>
+"Selenium," went on Tom, "was discovered in 1817, by J. J.
+Berzelius, and he gave it that name from the Greek word for moon,
+on account of selenium being so similar, in some ways, to
+tellurium. That last is named after the Latin word tellus, the
+earth."
+
+<P>
+"Do they dig it?" Ned wanted to know.
+
+<P>
+"Well, sometimes selenium is found in combination with metals, in
+the form of selenides, the more important minerals of that kind
+being eucharite, crooksite, clausthalite, naumannite and zorgite--"
+
+<P>
+"Good night!" interrupted Ned, with a laugh, holding up his hands.
+"Stop it, Tom!" he pleaded. "You'll give me a headache with all
+those big words."
+
+<P>
+"Oh, they're easy, once you get used to them," said the young
+inventor, with a smile. "Perhaps it will be easier if I say that
+sometimes selenium is found in native sulphur. Selenium is usually
+obtained from the flue-dust or chamber deposits of some factory
+where sulphuric acid is made. They take this dust and treat it
+with acids until they get the pure selenium. Sometimes selenium
+comes in crystal forms, and again it is combined with various
+metals for different uses."
+
+<P>
+"There's one good thing about it. There are several varieties, and
+I'll try them all before I give up."
+
+<P>
+"That's the way to talk!" cried Ned. "Never say die! Don't give up
+the ship, and all that. But, Tom, what you need now is a little
+fun. You've been poking away at this too long. Come on out on the
+lake, and have a ride in the motor boat. It will do you good. It
+will do me good. I'm a bit rusty myself--been working hard lately.
+Come on--let's go out on the lake."
+
+<P>
+"I believe I will!" exclaimed Tom, after thinking it over for a
+moment. "I need a little fresh air. Sitting in that telephone
+booth, trying to get an image on a plate, and not succeeding, has
+gotten on my nerves. I want to write out an order for Koku to take
+to town, though. I want to get some fresh selenium, and then I'm
+going to make new plates."
+
+<P>
+Tom made some memoranda, and then, giving Koku the order for the
+chemist, the young inventor closed up his shop, and went with Ned
+down to Lake Carlopa, where the motor boat was moored.
+
+<P>
+This was not the same boat Tom had first purchased, some years
+ago, but a comparatively new and powerful craft.
+
+<P>
+"It sure is one grand little day for a ride," remarked Ned, as he
+got in the craft, while Tom looked over the engine.
+
+<P>
+"Yes, I'm glad you came over, and routed me out," said the young
+inventor. "When I get going on a thing I don't know enough to
+stop. Oh, I forgot something!"
+
+<P>
+"What?" asked Ned.
+
+<P>
+"I forgot to leave word about Mr. Railing's airship. It's all
+fixed and ready for him, but I put on a new control, and I wanted
+to explain to him about it. He might not know how to work it. I
+left word with father, though, that if he came for it he must not
+try it until he had seen me. I guess it will be all right. I don't
+want to go back to the house now."
+
+<P>
+"No, it's too far," agreed Ned.
+
+<P>
+"I have it!" exclaimed Tom. "I'll telephone to dad from here, not
+to let Halling go up until I come back. He may not come for his
+machine; but, if he does, it's best to be on the safe side Ned."
+
+<P>
+"Oh, sure."
+
+<P>
+Accordingly, Tom 'phoned from his boat-house, and Mr. Swift
+promised to see the bird-man if he called. Then Ned and Tom gave
+themselves up to the delights of a trip on the water.
+
+<P>
+The <i>Kilo</i>, which name Tom had selected for his new craft, was a
+powerful boat, and comfortable. It swept on down the lake, and
+many other persons, in their pleasure craft, turned to look at
+Tom's fine one.
+
+<P>
+"Lots of folks out to-day," observed Ned, as they went around a
+point of the shore.
+
+<P>
+"Yes, quite a number," agreed Tom, leaning forward to adjust the
+motor. "I wonder what's got into her?" he said, in some annoyance,
+as he made various adjustments. "One of the cylinders is missing."
+
+<P>
+"Maybe it needs a new spark plug," suggested Ned.
+
+<P>
+"Maybe. Guess I'll stop and put one in."
+
+<P>
+Tom slowed down the motor, and headed his boat over toward shore,
+intending to tie up there for a while.
+
+<P>
+As he shifted the wheel he heard a cry behind him, and at the same
+time a hoarse, domineering voice called out:
+
+<P>
+"Here, what do you mean, changing your course that way? Look out,
+or I'll run you down! Get out of my way, you land-lubber, you!"
+
+<P>
+Startled, Ned and Tom turned. They saw, rushing up on them from
+astern, a powerful red motor boat, at the wheel of which sat a
+stout man, with a very florid face and a commanding air.
+
+<P>
+"Get out of my way!" he cried. "I can't stop so short! Look out,
+or I'll run you down!"
+
+<P>
+Tom, with a fierce feeling of resentment at the fellow, was about
+to shift the course of the <i>Kilo</i>, but he was too late.
+
+<P>
+A moment later there came a smashing blow on the stern port
+quarter and the <i>Kilo</i> heeled over at a dangerous angle, while, with
+a rending, splintering sound of wood, the big red motorboat swept
+on past Tom and Ned, her rubstreak grinding along the side of the
+<i>Kilo</i>.
+
+
+
+
+
+<P>
+<A NAME="V"></A>
+<H3>Chapter V Sharp Words</H3>
+
+
+<P>
+"Great Scott, Tom! What happened?"
+
+<P>
+"I know as much as you, Ned. That fellow ran us down, that's all."
+
+<P>
+"Are we leaking?" and with this question Ned sprang from his place
+near the bow, and looked toward the stern, where the heaviest blow
+had been struck.
+
+<P>
+The <i>Kilo</i> had swung back to an even keel again, but was still
+bobbing about on the water.
+
+<P>
+"Any hole there?" cried Tom, as he swung the wheel over to point
+his craft toward shore, in case she showed a tendency to sink.
+
+<P>
+"I can't see any hole," answered Ned. "But water is coming in
+here."
+
+<P>
+"Then there's a leak all right! Probably some of the seams are
+opened, or it may be coming in around the shaft stuffing-box.
+Here, Ned, take the wheel, and I'll start up the engine again,"
+for with the blow the motor had stopped.
+
+<P>
+"What are you going to do?" asked Ned, as he again made his way
+forward.
+
+<P>
+"Take her to shore, of course. It's deep out here and I don't want
+her to go down at this point."
+
+<P>
+"Say, what do you think of that fellow, anyhow, Tom?"
+
+<P>
+"I wouldn't like to tell you. Look, he's coming back."
+
+<P>
+This was so, for, as the boys watched, the big red motor boat had
+swung about in a circle and was headed for them.
+
+<P>
+"I'll tell him what I think of him, at any rate," murmured Tom, as
+he bent over his motor. "And, later on, I'll let the lawyers talk
+to him."
+
+<P>
+"You mean you'll sue him, Tom?"
+
+<P>
+"Well, I'm certainly not going to let him run into me and spring a
+leak, for nothing. That won't go with me!"
+
+<P>
+By this time Tom had the motor started, but he throttled it down
+so that it just turned the propeller. With it running at full
+speed there was considerable vibration, and this would further
+open the leaking seams. So much water might thus be let in that
+the craft could not be gotten ashore.
+
+<P>
+"Head her over, Ned," cried Tom, when he found he had sufficient
+headway. "Steer for Ramsey's dock. There's a marine railway next
+to him, and I can haul her out for repairs."
+
+<P>
+"That's the talk, Tom!" cried his chum.
+
+<P>
+By this time the big, red motor boat was close beside Tom's craft.
+
+<P>
+The man at the wheel, a stout-bodied and stout-faced man, with a
+complexion nearly the color of his boat, glared at the two young
+men.
+
+<P>
+"What do you fellows mean?" called out the man, in deep booming
+tones--tones that he tried to make imposing, but which, to the
+trained ears of Tom and Ned, sounded only like the enraged bellow
+of some bully. "What do you mean, I say? Getting on my course like
+that!"
+
+<P>
+Ned could see Tom biting his lips, and clenching his hands to keep
+down his temper. But it was too much. To be run into, and then
+insulted, was more than Tom could stand.
+
+<P>
+"Look here!" he cried, standing up and facing the red-faced man,
+"I don't know who you are, and I don't care. But I'll tell you one
+thing--you'll pay for the damage you did to my boat!"
+
+<P>
+"I'll pay for it? Come, that's pretty good! Ha! Ha!" laughed the
+self-important man. "Why, I was thinking of making a complaint
+against you for crossing my course that way. If I find my boat is
+damaged I shall certainly do so anyhow. Have we suffered any
+damage, Snuffin?" and he looked back at a grimy-faced mechinician
+who was oiling the big, throbbing motor, which was now running
+with the clutch out.
+
+<P>
+"No, sir, I don't think we're damaged, sir," answered the man,
+deferentially.
+
+<P>
+"Well, it's a lucky thing for these land-lubbers that we aren't. I
+should certainly sue them. The idea of crossing my course the way
+they did. Weren't they in the wrong, Snuffin?"
+
+<P>
+The man hesitated for a moment, and glanced at Tom and Ned, as
+though asking their indulgence.
+
+<P>
+"Well, I asked you a question, Snuffin!" exclaimed the red-faced
+man sharply.
+
+<P>
+"Yes--yes, sir, they shouldn't have turned the way they did,"
+answered the man, in a low voice.
+
+<P>
+"Well, of all the nerve!" murmured Tom, and stopped his motor.
+Then, stepping to the side of his disabled and leaking boat, he
+exclaimed:
+
+<P>
+"Look here! Either you folks don't know anything about navigation
+rules, or you aren't heeding them. I had a perfect right to turn
+and go ashore when I did, for I found my engine was out of order,
+and I wanted to fix it. I blew the usual signal on the whistle,
+showing my intention to turn off my course, and if you had been
+listening you would have heard it."
+
+<P>
+"If you had even been watching you would have seen me shift, and
+then, coming on at the speed you did, it was your place to warn me
+by a whistle, so that I could keep straight on until you had
+passed me."
+
+<P>
+"But you did not. You kept right on and ran into me, and the only
+wonder is that you didn't sink me. Talk about me getting in your
+way! Why, you deliberately ran me down after I had given the right
+signal. I'll make a complaint against you, that's what I will."
+
+<P>
+If possible the red-faced man got even more rosy than usual. He
+fairly puffed up, he was so angry.
+
+<P>
+"Listen to that, will you, Snuffin!" he cried. "Listen to that! He
+says he blew his whistle to tell us he was going to turn in."
+
+<P>
+"That's what I did!" said Tom, calmly.
+
+<P>
+"Preposterous! Did you hear it, Snuffin?" puffed the important
+man.
+
+<P>
+"Yes--yes, I think I did, sir," answered the machinist, in a
+hesitating voice.
+
+<P>
+"You did? What! You mean to tell me you heard their whistle?"
+
+<P>
+"Yes--yes, sir!"
+
+<P>
+"Why--why--er--I--" the big man puffed and blew, but seemed to
+find no words in which to express himself. "Snuffin, I'll have a
+talk with you when we get home," he finally said. most
+significantly. "The idea of saying you heard a whistle blown!
+There was nothing of the kind! I shall make a complaint against
+these land-lubbers myself. Do you know who they are, Snuffin?"
+
+<P>
+"Yes--yes, sir," was the answer, as the man glanced at Tom. "At
+least I know one of them, sir."
+
+<P>
+"Very good. Give me his name. I'll attend to the rest."
+
+<P>
+Tom looked at the big man sharply. He had never seen him before,
+as far as he could recall. As for the machinist, the young
+inventor had a dim recollection that once the man might have
+worked in his shop.
+
+<P>
+"Go ahead, Snuffin!" said the big man, mopping his face with a
+large silk handkerchief, which, even at that distance, gave out a
+powerful perfume. "Go ahead, Snuffin, and we will settle this
+matter later," and, adjusting a large rose in his buttonhole, the
+self-important individual took his place on the cushioned seat at
+the wheel, while the big red motor boat drew off down the river.
+
+<P>
+"Well, of all the nerve!" gasped Ned. "Isn't he the limit?"
+
+<P>
+"Never mind," spoke Tom, with a little laugh. "I'm sorry I lost my
+temper, and even bothered to answer him. We'll let the lawyers do
+the rest of the talking. Take the wheel, Ned."
+
+<P>
+"But are you going to let him get away like this, Tom? Without
+asking him to pay for the damage to your boat, when he was clearly
+in the wrong?"
+
+<P>
+"Oh, I'll ask him to pay all right; but I'll do it the proper way.
+Now come on. If we stay here chinning much longer the <i>Kilo</i> will go
+down. I must find out who he is. I think I know Snuffin--he used
+to work for me, I now recall."
+
+<P>
+"Don't you know who that big man is?" asked Ned, as he took the
+wheel, while Tom again started the motor. The water was now almost
+up to the lower rim of the fly wheel.
+
+<P>
+"No; who is he?" asked Tom.
+
+<P>
+"Shallock Peters."
+
+<P>
+"Well, I know as much as I did before," laughed Tom. "That doesn't
+tell me anything."
+
+<P>
+"Why, I thought everybody in the town knew Shallock Peters," went
+on Ned. "He tried to do some business with our bank, but was
+turned down. I hear he's gone to the other one, though. He's what
+we call a get-rich-quick schemer, Tom--a promoter."
+
+<P>
+"I thought he acted like that sort of a character."
+
+<P>
+"Well, that's what he is. He's got half a dozen schemes under way,
+and he hasn't been in town over a month. I wonder you haven't seen
+or heard of him."
+
+<P>
+"I've been too busy over my photo telephone."
+
+<P>
+"I suppose so. Well, this fellow Peters struck Shopton about a
+month ago. He bought the old Wardell homestead, and began to show
+off at once. He's got two autos, and this big motor boat. He
+always goes around with a silk hat and a flower in his buttonhole.
+A big bluff--that's what he is."
+
+<P>
+"He acted so to me," was Tom's comment. "Well, he isn't going to
+scare me. The idea! Why, he seemed to think we were in the wrong;
+whereas he was, and his man knew it, too."
+
+<P>
+"Yes, but the poor fellow was afraid to say so. I felt sorry for
+him."
+
+<P>
+"So did I," added Tom. "Well, <i>Kilo</i> is out of commission for the
+present. Guess we'll have to finish our outing by walking, Ned."
+
+<P>
+"Oh, I don't mind. But it makes me mad to have a fellow act the
+way he did."
+
+<P>
+"Well, there's no good in getting mad," was Tom's smiling
+rejoinder. "We'll take it out of him legally. That's the best way
+in the end. But I can't help saying I don't like Mr. Shallock
+Peters."
+
+<P>
+"And I don't either," added Ned.
+
+
+
+
+
+<P>
+<A NAME="VI"></A>
+<H3>Chapter VI A Warning</H3>
+
+
+<P>
+"There, she's about right now, Ned. Hold her there!"
+
+<P>
+"Aye, aye, Captain Tom!"
+
+<P>
+"Jove, she's leaking like a sieve! We only got her here just in
+time!"
+
+<P>
+"That's right," agreed Ned.
+
+<P>
+Tom and his chum had managed to get the <i>Kilo</i> to Ramsey's dock, and
+over the ways of the inclined marine railway that led from the
+shop on shore down into the river. Then, poling the craft along,
+until she was in the "cradle," Ned held her there while Tom went
+on shore to wind up the windlass that pulled the car, containing
+the boat, up the incline.
+
+<P>
+"I'll give you a hand, as soon as I find she sets level," called
+Ned, from his place in the boat.
+
+<P>
+"All right--don't worry. There are good gears on this windlass,
+and she works easy," replied Tom.
+
+<P>
+In a short time the boat was out of the water, but, as Tom grimly
+remarked, "the water was not out of her," for a stream poured from
+the stuffing-box, through which the propeller shaft entered, and
+water also ran out through the seams that had been opened by the
+collision.
+
+<P>
+"Quite a smash, Tom," observed the boat repairer, when he had come
+out to look over the <i>Kilo</i>. "How'd it happen?"
+
+<P>
+"Oh, Shallock Peters, with his big red boat, ran into us!" said
+Ned, sharply.
+
+<P>
+"Ha, Peters; eh?" exclaimed the boatman. "That's the second craft
+he's damaged inside a week with his speed mania. There's Bert
+Johnson's little speeder over there," and he pointed to one over
+which some men were working. "Had to put a whole new stern in her,
+and what do you think that man Peters did?"
+
+<P>
+"What?" asked Tom, as he bent down to see how much damage his
+craft had sustained.
+
+<P>
+"He wouldn't pay young Johnson a cent of money for the repairs,"
+went on Mr. Houston, the boatman. "It was all Peters's fault,
+too."
+
+<P>
+"Couldn't he make him pay?" asked Tom.
+
+<P>
+"Well, young Johnson asked for it--no more than right, too; but
+Peters only sneered and laughed at him."
+
+<P>
+"Why didn't he sue?" asked Ned.
+
+<P>
+"Costs too much money to hire lawyers, I reckon. So he played you
+the same trick; eh. Tom?"
+
+<P>
+"Pretty much, yes. But he won't get off so easily, I can tell you
+that!" and there was a grim and determined look on the face of the
+young inventor. "How long will it take to fix my boat, Mr.
+Houston?"
+
+<P>
+"Nigh onto two weeks, Tom. I'm terrible rushed now."
+
+<P>
+Tom whistled ruefully.
+
+<P>
+"I could do it myself quicker, if I could get her back to my
+shop," he said. "But she'd sink on the home trip. All right, do
+the best you can, Mr. Houston."
+
+<P>
+"I will that, Tom."
+
+<P>
+The two chums walked out of the boat-repair place.
+
+<P>
+"What are you going to do, Tom?" asked Ned, as they strolled
+along.
+
+<P>
+"Well, since we can't go motor boating, I guess I may as well go
+back and see if that new supply of selenium has come. I do want to
+get my photo telephone working, Ned."
+
+<P>
+"And that's all the outing you're going to take--less than an
+hour!" exclaimed Ned, reproachfully.
+
+<P>
+"Oh, well, all you wanted to do was to get me out of a rut, as you
+called it," laughed Tom. "And you've done it--you and Mr. Peters
+together. It jolted up my brain, and I guess I can think better
+now. Come on back and watch me tinker away, Ned."
+
+<P>
+"Not much! I'm going to stay out and get some fresh air while I
+can. You'd better, too."
+
+<P>
+"I will, later."
+
+<P>
+So Tom turned back to his workshop, and Ned strolled on into the
+country, for his day's work at the bank was over. And for some
+time after that--until far into the night--Tom Swift worked at the
+knotty problem of the photo telephone.
+
+<P>
+But the young inventor was baffled. Try as he might, he could not
+get the image to show on the metal plate, nor could he get any
+results by using a regular photographic plate, and developing it
+afterward.
+
+<P>
+"There is something wrong with the transmission of the light waves
+over the wire," Tom confessed to his father.
+
+<P>
+"You'll never do it, Tom," said the aged inventor. "You are only
+wasting a whole lot of time."
+
+<P>
+"Well, as I haven't anything else to do now, it isn't much loss,"
+spoke Tom, ruefully. "But I'm going to make this work, Dad!"
+
+<P>
+"All right, son. It's up to you. Only I tell you it can't be
+done."
+
+<P>
+Tom, himself, was almost ready to admit this, when, a week later,
+he seemed to be no nearer a solution of the problem than he was at
+first. He had tried everything he could think of, and he had
+Eradicate and Koku, the giant, almost distracted, by making them
+stay in small telephone booths for hours at a time, while the
+young inventor tried to get some reflection of one face or the
+other to come over the wire.
+
+<P>
+Koku finally got so nervous over the matter, that he flatly
+refused to "pose" any longer, so Tom was forced to use Eradicate.
+As for that elderly man of all work, after many trials, all
+unsuccessful, he remarked:
+
+<P>
+"Massa Tom, I reckon I knows what's wrong."
+
+<P>
+"Yes, Rad? Well, what is it?"
+
+<P>
+"Mah face am too black--dat's de trouble. You done want a white-complected
+gen'man to stand in dat booth an' look at dat lookin'
+glass plate. I'se too black! I suah is!"
+
+<P>
+"No, that isn't it, Rad," laughed Tom, hopelessly. "If the thing
+works at all it will send a black man's face over the wire as well
+as a white man's. I guess the truth of it is that you're like
+Koku. You're getting tired. I don't know as I blame you. I'm
+getting a bit weary myself. I'm going to take a rest. I'll send
+for another kind of selenium crystals I've heard of, and we'll try
+them. In the meanwhile--I'll take a little vacation."
+
+<P>
+"Get out my small airship, Rad, and I'll take a little flight."
+
+<P>
+"Dat's de way to talk, Massa Tom," was the glad rejoinder.
+
+<P>
+"I'm going over to see Mr. Damon, Father," announced Tom to Mr.
+Swift a little later, when his speedy monoplane was waiting for
+him. "I haven't seen him in some time, and I'd like to get at the
+truth of what Mr. Halling said about Mr. Damon's fortune being in
+danger. I'll be back soon."
+
+<P>
+"All right, Tom. And say--"
+
+<P>
+"Yes, Dad, what is it?" asked Tom, as he paused in the act of
+getting in the seat.
+
+<P>
+"If he wants any ready cash, you know we've got plenty."
+
+<P>
+"Oh, sure. I was going to tell him we'd help him out."
+
+<P>
+Then, as Koku spun the propeller blades, Tom grasped the steering
+wheel, and, tilting the elevating rudder, he was soon soaring into
+the air, he and his craft becoming smaller and smaller as they
+were lost to sight in the distance, while the rattle and roar of
+the powerful motor became fainter.
+
+<P>
+In a comparatively short time Tom had made a successful landing in
+the big yard in front of Mr. Damon's house, and, walking up the
+path, kept a lookout for his friend.
+
+<P>
+"I wonder why he didn't come out to meet me?" mused Tom, for
+usually when the eccentric man heard the throbbing of Tom's motor,
+he was out waiting for the young inventor. But this time it was
+not the case.
+
+<P>
+"Is Mr. Damon in?" Tom asked of the maid who answered his ring.
+
+<P>
+"Yes, Mr. Swift. You'll find him in the library," and she ushered
+him in.
+
+<P>
+"Oh, hello, Tom," greeted Mr. Damon, but the tone was so listless,
+and his friend's manner so gloomy that the young inventor was
+quite embarrassed.
+
+<P>
+"Have a chair," went on Mr. Damon. "I'll talk to you in a minute,
+Tom. I've got to finish this letter, and it's a hard one to write,
+let me tell you."
+
+<P>
+Now Tom was more astonished than ever. Not once had Mr. Damon
+"blessed," anything, and when this did not happen Tom was sure
+something was wrong. He waited until his friend had sealed the
+letter, and turned to him with a sigh. Then Tom said boldly:
+
+<P>
+"Mr. Damon, is it true that you're having hard luck--in money
+matters?"
+
+<P>
+"Why, yes, Tom, I'm afraid I am," was the quick answer. "But who
+told you?"
+
+<P>
+"Grant Halling. He was over to get me to fix his airship," and Tom
+briefly related what had happened.
+
+<P>
+"Oh, yes, I did mention the matter to him," went on Mr. Damon, and
+his tone was still listless. "So he told you; did he? Well,
+matters aren't any better, Tom. In fact, they're worse. I just had
+to write to a man who was asking for help, and I had to refuse
+him, though he needs it very much. The truth is I hadn't the
+money. Tom, I'm afraid I'm going to be a very poor man soon."
+
+<P>
+"Impossible, Mr. Damon! Why, I thought your investments--"
+
+<P>
+"I've made some bad ones of late, Tom. I've been pretty foolish,
+I'm afraid. I drew out some money I had in government bonds, and
+invested in certain stocks sold by a Mr. Shallock Peters."
+
+<P>
+"Shallock Peters!" cried Tom, almost jumping out of his chair.
+"Why, I know him--I mean I've met him."
+
+<P>
+"Have you, Tom? Well, then, all I've got to say is to steer clear
+of him, my boy. Don't have anything to do with him," and, with
+something of a return of his usual energy Mr. Damon banged his
+fist down on his desk. "Give him a wide berth, Tom, and if you see
+him coming, turn your back. He'd talk a miser into giving him his
+last cent. Keep away from Shallock Peters, Tom. Bless my necktie,
+he's a scoundrel, that's what he is!" and again Mr. Damon banged
+his desk forcibly.

+
+
+<P>
+"Well, I'm glad of one thing!" exclaimed Tom, when the ink bottle
+and the paper cutter on Mr. Damon's desk had ceased rattling,
+because of the violence of the blow. "I'm glad of one thing."
+
+<P>
+"What's that, Tom?" asked his friend.
+
+<P>
+"I heard you bless something at last--the first time since I came
+in."
+
+<P>
+"Oh!" and Mr. Damon laughed. "Well, Tom, I haven't been blessing
+things lately--that's a fact. I haven't had the heart for it.
+There are too many business complications. I wish I'd never met
+this Peters."
+
+<P>
+"So do I," said Tom. "My motor boat would not have been damaged
+then."
+
+<P>
+"Did he do that, Tom?"
+
+<P>
+"He certainly did, and then he accused me of being at fault."
+
+<P>
+"That would be just like him. Tell me about it, Tom."
+
+<P>
+When the young inventor finished the story of the collision Mr.
+Damon sat silent for a moment. Then he remarked slowly:
+
+<P>
+"That's just like Peters. A big bluff--that's what he is. I wish
+I'd discovered that fact sooner--I'd be money in pocket. But I
+allowed myself to be deceived by his talk about big profits. At
+first he seemed like a smart business man, and he certainly had
+fine recommendations. But I am inclined to believe, now, that the
+recommendations were forged."
+
+<P>
+"What did he do to you, Mr. Damon?" asked Tom, with ready
+sympathy.
+
+<P>
+"It's too complicated to go into details over, Tom, but to make a
+long story short, he got me to invest nearly all my fortune in
+some enterprises that, I fear, are doomed to failure. And if they
+do fail, I'll be a ruined man."
+
+<P>
+"No, you won't!" exclaimed Tom. "That's one reason why I came here
+to-day. Father told me to offer you all the ready money you needed
+to get out of your trouble. How much do you need, Mr. Damon?"
+
+<P>
+"Bless my collar button! That's like your father, Tom," and now
+Mr. Damon seemed more like his old self. "Bless my shoes, a man
+never knows who his real friends are until trouble comes. I can't
+say how I thank you and your father, Tom. But I'm not going to
+take advantage of him."
+
+<P>
+"It wouldn't be taking any advantage of him, Mr. Damon. He has
+money lying idle, and he'd like to have you use it."
+
+<P>
+"Well, Tom, I might use it, if I had only myself to think about.
+But there's no use in throwing good money after bad. If I took
+yours now this fellow Peters would only get it, and that would be
+the last of it."
+
+<P>
+"No, Tom, thank you and your father just the same, but I'll try to
+weather the storm a bit longer myself. Then, if I do go down I
+won't drag anybody else with me. I'll hang on to the wreck a bit
+longer. The storm may blow over, or--or something may happen to
+this fellow Peters."
+
+<P>
+"Has he really got you in his grip, Mr. Damon?"
+
+<P>
+"He has, and, to a certain extent, it's my own fault. I should
+have been suspicious of him. And now, Tom, let me give you a
+further word of warning. You heard me say to steer clear of this
+Peters?"
+
+<P>
+"Yes, and I'm going to. But I'm going to make him pay for damaging
+my boat, if I possibly can."
+
+<P>
+"Maybe it would be wiser not to try that, Tom. I tell you he's a
+tricky man. And one thing more. I have heard that this man Peters
+makes a specialty of organizing companies to take up new
+inventions."
+
+<P>
+"Is that so?" asked Tom, interestedly.
+
+<P>
+"Yes, but that's as far as it goes. Peters gets the invention, and
+the man, out of whose brain it came, gets nothing."
+
+<P>
+"In other words, he swindles them?"
+
+<P>
+"That's it, Tom. If not in one way, then in another. He cheats
+them out of the profits of their inventions. So I want to warn you
+to be on the lookout."
+
+<P>
+"Don't worry," said Tom. "Peters will get nothing from my father
+or me. We'll be on our guard. Not that I think he will try it, but
+it's just as well to be warned. I didn't like him from the moment
+he ran into me, and, now that I know what he has done to you, I
+like him still less. He won't get anything from me!"
+
+<P>
+"I'm glad to hear you say so, Tom. I wish he'd gotten nothing out
+of me."
+
+<P>
+"Are you sure you won't let my father help you, financially, Mr.
+Damon?"
+
+<P>
+"No, Tom, at least not for the present. I'm going to make another
+fight to hold on to my fortune. If I find I can't do it alone,
+then I'll call on you. I'm real glad you called. Bless my
+shoestring! I feel better now."
+
+<P>
+"I'm glad of it," laughed Tom, and he saw that his friend was in a
+better state of mind, as his "blessings" showed.
+
+<P>
+Tom remained for a little longer, talking to Mr. Damon, and then
+took his leave, flying back home in the airship.
+
+<P>
+"Gen'man t' see yo', Massa Tom," announced Eradicate, as he helped
+Tom wheel the monoplane back into the shed.
+
+<P>
+"Is that so, Rad? Where is he?"
+
+<P>
+"Settin' in th' library. Yo' father am out, so I asted him in
+dere."
+
+<P>
+"That's right, Rad. Who is he, do you know?"
+
+<P>
+"No, sah, Massa Tom, I doan't. He shore does use a pow'ful nice
+perfume on his pocket hanky, though. Yum-yum!"
+
+<P>
+"Perfume!" exclaimed Tom, his mind going back to the day he had
+had the trouble with Mr. Peters. "Is he a big, red-faced man,
+Rad?"
+
+<P>
+"No, sah, Massa Tom. He's a white-faced, skinny man."
+
+<P>
+"Then it can't be Peters," mused Tom. "I guess perhaps it's that
+lawyer I wrote to about bringing suit to get back what it cost me
+to have the <i>Kilo</i> fixed. I'll see him at once. Oh, by the way, it
+isn't Mr. Grant Halling; is it? The gentleman who got tangled up
+in our aerials with his airship? Is it he?"
+
+<P>
+"No, sah, Massa Tom. 'Tain't him."
+
+<P>
+"I thought perhaps he had gotten into more trouble," mused Tom, as
+he took off his airship "togs," and started for the house. For Mr.
+Halling had called for his repaired airship some time ago, and had
+promised to pay Tom another and more conventional visit, some
+future day.
+
+<P>
+Tom did not know the visitor whom he greeted in the library a
+little later. The man, as Eradicate had said, was rather pale of
+face, and certainly he was not very fleshy.
+
+<P>
+"Mr. Tom Swift, I think?" said the man, rising and holding out his
+hand.
+
+<P>
+"That's my name. I don't believe I know you, though."
+
+<P>
+"No, I haven't your reputation," said the man, with a laugh that
+Tom did not like. "We can't all be great inventors like you," and,
+somehow, Tom liked the man less than before, for he detected an
+undertone of sneering patronage in the words. Tom disliked praise,
+and he felt that this was not sincere.
+
+<P>
+"I have called on a little matter of business," went on the man.
+"My name is Harrison Boylan, and I represent Mr. Shallock Peters."
+
+<P>
+Instinctively Tom stiffened. Receiving a call from a
+representative of the man against whom Mr. Damon had warned him
+only a short time before was a strange coincidence, Tom thought.
+
+<P>
+"You had some little accident, when your motor boat and that of
+Mr. Peters collided, a brief time ago; did you not?" went on Mr.
+Boylan.
+
+<P>
+"I did," said Tom, and, as he motioned the caller to be seated Tom
+saw, with a start, that some of the drawings of his photo
+telephone were lying on a desk in plain sight. They were within
+easy reach of the man, and Tom thought the sheets looked as though
+they had been recently handled. They were not in the orderly array
+Tom had made of them before going out.
+
+<P>
+"If he is a spy, and has been looking at them," mused Tom, "he may
+steal my invention." Then he calmed himself, as he realized that
+he, himself, had not yet perfected his latest idea. "I guess he
+couldn't make much of the drawings," Tom thought.
+
+<P>
+"Yes, the collision was most unfortunate," went on Mr. Boylan,
+"and Mr. Peters has instructed me to say--"
+
+<P>
+"If he's told you to say that it was my fault, you may as well
+save your time," cut in Tom. "I don't want to be impolite, but I
+have my own opinion of the affair. And I might add that I have
+instructed a lawyer to begin a suit against Mr. Peters--"
+
+<P>
+"No necessity for that at all!" interrupted the man, in soft
+accents. "No necessity at all. I am sorry you did that, for there was
+no need. Mr. Peters has instructed me to say that he realizes the
+accident was entirely his own fault, and he is very willing--nay,
+anxious, to pay all damages. In fact, that is why I am here, and I am
+empowered, my dear Mr. Swift, to offer you five hundred dollars, to
+pay for the repairs to your motor boat. If that is not enough--"
+
+<P>
+The man paused, and drew a thick wallet front his pocket. Tom felt
+a little embarrassed over what he had said.
+
+<P>
+"Oh," spoke the young inventor, "the repair bill is only about
+three hundred dollars. I'm sorry--"
+
+<P>
+"Now that's all right, Mr. Swift! It's all right," and the man,
+with his soft words, raised a white, restraining hand. "Not
+another word. Mr. Peters did not know who you were that day he so
+unfortunately ran into you. If he had, he would not have spoken as
+he did. He supposed you were some amateur motor-boatist, and he
+was--well, he admits it--he was provoked."
+
+<P>
+"Since then he has made inquiries, and, learning who you were, he
+at once authorized me to make a settlement in full. So if five
+hundred dollars--"
+
+<P>
+"The repair bill," said Tom, and his voice was not very cordial,
+in spite of the other's persuasive smile, "the bill came to three
+hundred forty-seven dollars. Here is the receipted bill. I paid
+it, and, to be frank with you, I intended bringing suit against
+Mr. Peters for that sum."
+
+<P>
+"No need, no need at all, I assure you!" interrupted Mr. Boylan,
+as he counted off some bills. "There you are, and I regret that
+you and Mr. Peters had such a misunderstanding. It was all his
+fault, and he wants to apologize to you."
+
+<P>
+"The apology is accepted," said Tom, and he smiled a trifle. "Also
+the money. I take it merely as a matter of justice, for I assure
+you that Mr. Peters's own machinist will say the accident was his
+employer's fault."
+
+<P>
+"No doubt of it, not the least in the world," said the caller.
+"And now that I have this disagreeable business over, let me speak
+of something more pleasant."
+
+<P>
+Instinctively Tom felt that now the real object of the man's call
+would be made plain--that the matter of paying the damages was
+only a blind. Tom steeled himself for what was to come.
+
+<P>
+"You know, I suppose," went on Mr. Boylan, smiling at Tom, "that
+Mr. Peters is a man of many and large interests."
+
+<P>
+"I have heard something like that," said Tom, cautiously.
+
+<P>
+"Yes. Well, he is an organizer--a promoter, if you like. He
+supplies the money for large enterprises, and is, therefore, a
+benefactor of the human race. Where persons have no cash with
+which to exploit their--well, say their inventions. Mr. Peters
+takes them, and makes money out of them."
+
+<P>
+"No doubt," thought Tom, grimly.
+
+<P>
+"In other cases, where an inventor is working at a handicap, say
+with too many interests, Mr. Peters takes hold of one of his
+ideas, and makes it pay much better than the inventor has been
+able to do."
+
+<P>
+"Now, Mr. Peters has heard of you, and he would like to do you
+good."
+
+<P>
+"Yes, I guess he would," thought Tom. "He would like to do me--and
+do me good and brown. Here's where I've got to play a game
+myself."
+
+<P>
+"And so," went on Mr. Boylan, "Mr. Peters has sent me to you to
+ask you to allow him to exploit one, or several, of your
+inventions. He will form a large stock company, put one of your
+inventions on the market, and make you a rich man. Now what do you
+say?" and he looked at Tom and smiled--smiled, the young inventor
+could not help thinking, like a cat looking at a mouse. "What do
+you say, Mr. Swift?"
+
+<P>
+For a moment Tom did not answer. Then getting up and opening the
+library door, to indicate that the interview was at an end, the
+young inventor smiled, and said:
+
+<P>
+"Tell Mr. Peters that I thank him, but that I have nothing for him
+to exploit, or with which to form a company to market."
+
+<P>
+"Wha--what!" faltered the visitor. "Do you mean to say you will
+not take advantage of his remarkable offer?"
+
+<P>
+"That's just what I mean to say," replied Tom, with a smile.
+
+<P>
+"You won't do business with Mr. Peters? You won't let him do you
+good?"
+
+<P>
+"No," said Tom, quietly.
+
+<P>
+"Why--why, that's the strangest--the most preposterous thing I
+ever heard of!" protested Mr. Boylan. "What--what shall I say to
+Mr. Peters?"
+
+<P>
+"Tell him," said Tom, "tell him, from me, and excuse the slang, if
+you like, but tell him there is--nothing doing!"
+
+
+
+
+
+<P>
+<A NAME="VIII"></A>
+<H3>Chapter VIII Tom Is Baffled</H3>
+
+
+<P>
+Amazement held Mr. Boylan silent for a moment, and then, staring
+at Tom, as though he could not believe what he had heard the young
+inventor say, the representative of Mr. Peters exclaimed:
+
+<P>
+"Nothing doing?"
+
+<P>
+"That's what I said," repeated Tom, calmly.
+
+<P>
+"But--but you don't understand, I'm afraid."
+
+<P>
+"Oh, but indeed I do."
+
+<P>
+"Then you refuse to let my friend, Mr. Peters, exploit some of
+your inventions?"
+
+<P>
+"I refuse absolutely."
+
+<P>
+"Oh, come now. Take an invention that hasn't been very
+successful."
+
+<P>
+"Well, I don't like to boast," said Tom with a smile, "but all of
+my inventions have been successful. They don't need any aid from
+Mr. Peters, thank you."
+
+<P>
+"But this one!" went on the visitor eagerly, "this one about some
+new kind of telephone," and he motioned to the drawings on the
+table. "Has that been a success? Excuse me for having looked at
+the plans, but I did not think you would mind. Has that telephone
+been a success? If it has not perhaps Mr. Peters could form a
+company to--"
+
+<P>
+"How did you know those drawings referred to a telephone?" asked
+Tom, suspiciously, for the papers did not make it clear just what
+the invention was.
+
+<P>
+"Why, I understood--I heard, in fact, that you were working on a
+new photo telephone, and--"
+
+<P>
+"Who told you?" asked Tom quickly.
+
+<P>
+"Oh, no one in particular. The colored man who sent me here
+mentioned--"
+
+<P>
+"Eradicate!" thought Tom. "He must have been talking. That isn't
+like him. I must look into this."
+
+<P>
+Then to his caller he said:
+
+<P>
+"Really, you must excuse me, Mr. Boylan, but I don't care to do
+any business with Mr. Peters. Tell him, with my thanks, that there
+is really nothing doing in his line. I prefer to exploit my own
+inventions."
+
+<P>
+"That is your last word?"
+
+<P>
+"Yes," returned Tom, as he gathered up the drawings.
+
+<P>
+"Well," said Mr. Boylan, and Tom could not help thinking there was
+a veiled threat in his tones, "you will regret this. You will be
+sorry for not having accepted this offer."
+
+<P>
+"I think not," replied Tom, confidently. "Good-day."
+
+<P>
+The young inventor sat for some time thinking deeply, when his
+visitor had gone. He called Eradicate to him, and gently
+questioned the old colored man, for Eradicate was ageing fast of
+late, and Tom did not want him to feel badly.
+
+<P>
+It developed that the servant had been closely cross-questioned by
+Mr. Boylan, while he was waiting for Tom, and it was small wonder
+that the old colored man had let slip a reference to the photo
+telephone. But he really knew nothing of the details of the
+invention, so he could have given out no secrets.
+
+<P>
+"But at the same time," mused Tom, "I must be on guard against
+these fellows. That Boylan seems a pretty slick sort of a chap. As
+for Peters, he's a big 'bluff,' to be perfectly frank. I'm glad I
+had Mr. Damon's warning in mind, or I might have been tempted to
+do business with him."
+
+<P>
+"Now to get busy at this photo telephone again. I'm going to try a
+totally different system of transmission. I'll use an alternating
+current on the third wire, and see if that makes it any better.
+And I'll put in the most sensitive selenium plate I can make. I'm
+going to have this thing a success."
+
+<P>
+Tom carefully examined the drawings of his invention, at which
+papers Mr. Boylan had confessed to looking. As far as the young
+inventor could tell none was missing, and as they were not
+completed it would be hard work for anyone not familiar with them
+to have gotten any of Tom's ideas.
+
+<P>
+"But at the same time I'm going to be on my guard," mused Tom.
+"And now for another trial."
+
+<P>
+Tom Swift worked hard during the following week, and so closely
+did he stick to his home and workshop that he did not even pay a
+visit to Mr. Damon, so he did not learn in what condition that
+gentleman's affairs were. Tom even denied himself to his chum Ned,
+so taken up was the young inventor with working out the telephone
+problem, until Ned fairly forced himself into the shop one day,
+and insisted on Tom coming out.
+
+<P>
+"You need some fresh air!" exclaimed Ned. "Come on out in the
+motor boat again. She's all fixed now; isn't she?"
+
+<P>
+"Yes," answered Tom, "but--"
+
+<P>
+"Oh, 'but me no buts,' as Mr. Shakespeare would say. Come on, Tom.
+It will do you good. I want a spin myself."
+
+<P>
+"All right, I will go for a little while," agreed Tom. "I am
+feeling a bit rusty, and my head seems filled with cobwebs."
+
+<P>
+"Can't get the old thing to come out properly; eh?"
+
+<P>
+"No. I guess dad was more than half right when he said it couldn't
+be done. But I haven't given up. Maybe I'll think of some new plan
+if I take a little run. Come along."
+
+<P>
+They went down to the boat house, and soon were out on the lake in
+the <i>Kilo</i>.
+
+<P>
+"She runs better since you had her fixed," remarked Ned.
+
+<P>
+"Yes, they did a good job."
+
+<P>
+"Did you sue Peters?"
+
+<P>
+"Didn't have to. He sent the money," and Tom told of his interview
+with Mr. Boylan. This was news to Ned, as was also the financial
+trouble of Mr. Damon.
+
+<P>
+"Well," said the young banker, "that bears out what I had heard of
+Peters--that he was a get-rich-quick chap, and a good one to steer
+clear of."
+
+<P>
+"Speaking of steering clear," laughed Tom, "there he is now, in
+his big boat," and he pointed to a red blur coming up the lake.
+"I'll give him a wide enough berth this time."
+
+<P>
+But though Mr. Peters, in his powerful motor boat, passed close to
+Tom's more modest craft, the big man did not glance toward our
+hero and his chum. Nor did Mr. Boylan, who was with his friend,
+look over.
+
+<P>
+"I guess they've had enough of you," chuckled Ned.
+
+<P>
+"Probably he wishes he hadn't paid me that money," said Tom. "Very
+likely he thought, after he handed it over, that I'd be only too
+willing to let him manage one of my inventions. But he has another
+guess coming."
+
+<P>
+Tom and Ned rode on for some distance, thoroughly enjoying the
+spin on the lake that fine Summer day. They stopped for lunch at a
+picnic resort, and coming back in the cool of the evening they
+found themselves in the midst of a little flotilla of pleasure
+craft, all decorated with Japanese lanterns.
+
+<P>
+"Better slow down a bit," Ned advised Tom, for many of the
+pleasure craft were canoes and light row boats. "Our wash may
+upset some of them."
+
+<P>
+"Guess you're right, old man," agreed Tom, as he closed the
+gasolene throttle, to reduce speed. Hardly had he done so than
+there broke in upon the merry shouts and singing of the pleasureseekers
+the staccato exhaust of a powerful motor boat, coming
+directly behind Tom's craft.
+
+<P>
+Then came the shrill warning of an electrical siren horn.
+
+<P>
+"Somebody's in a hurry," observed Tom.
+
+<P>
+"Yes," answered Ned. "It sound's like Peters's boat, too."
+
+<P>
+"It is!" exclaimed Tom. "Here he comes. He ought to know better
+than to cut through this raft of boats at that speed."
+
+<P>
+"Is he headed toward us?"
+
+<P>
+"No, I guess he's had enough of that. But look at him!"
+
+<P>
+With undiminished speed the burly promoter was driving his boat
+on. The big vibrating horn kept up its clamor, and a powerful
+searchlight in front dazzled the eyes.
+
+<P>
+"Look out! Look out!" cried several.
+
+<P>
+Many of the rowers and paddlers made haste to clear a lane for the
+big, speedy motor craft, and Peters and his friends (for there
+were several men in his boat now) seemed to accept this as a
+matter of course, and their right.
+
+<P>
+"Somebody'll be swamped!" exclaimed Ned.
+
+<P>
+Hardly had he spoken than, as the big red boat dashed past in a
+smother of foam, there came a startled cry in girls' voices.
+
+<P>
+"Look!" cried Tom. "That canoe's upset! Speed her up, Ned! We've
+got to get 'em!"
+
+
+
+
+
+<P>
+<A NAME="IX"></A>
+<H3>Chapter IX A Gleam Of Hope</H3>
+
+
+<P>
+"Where are they?"
+
+<P>
+"Who are they?"
+
+<P>
+"Over this way! There's their canoe!"
+
+<P>
+"Look out for that motor boat!"
+
+<P>
+"Who was it ran them down? They ought to be arrested!"
+
+<P>
+These were only a few of the cries that followed the upsetting of
+the frail canoe by the wash from the powerful red boat. On Tom's
+<i>Kilo</i> there was a small, electrical searchlight which he had not
+yet switched on. But, with his call to Ned Newton to speed up the
+motor, that had been slowed down, Tom, with one turn of his
+fingers, set the lamp aglow, while, with the other hand, he
+whirled the wheel over to head his craft for the spot where he saw
+two figures struggling in the water.
+
+<P>
+Fortunately the lanterns on the various canoes and row-boats, as
+well as the light on the bow of Tom's <i>Kilo</i>, made an illumination
+that gave the rescuers a good chance to work. Many other boats
+besides Tom's had headed for the scene, but his was the more
+practical, since the others--all quite small ones--were pretty
+well filled.
+
+<P>
+"There they are, Ned!" Tom suddenly cried. "Throw out the clutch!
+I'll get 'em!"
+
+<P>
+"Want any help?"
+
+<P>
+"No, you stay at the engine, and mind what I say. Reverse now!
+We're going to pass them!"
+
+<P>
+Ned threw in the backing gear, and the screw churned the water to
+foam under the stern of the <i>Kilo</i>.
+
+<P>
+Tom leaned over the bow, and made a grab for the gasping,
+struggling figure of a girl in the water. At the same time he had
+tossed overboard a cork life ring, attached to a rope which, in
+turn, was made fast to the forward deck-cleat. "Grab that!" cried
+Tom. "Hold on, and I'll have you out in a second! That's enough,
+Ned! Shut her off!"
+
+<P>
+The <i>Kilo</i> came to a standstill, and, a second later, Tom had pulled
+into his boat one of the girls. She would have collapsed, and
+fallen in a heap on the bottom boards, had not Ned, who had come
+forward from the engine, caught her.
+
+<P>
+Then Tom, again leaning over the side, pulled in the other girl,
+who was clinging to the life ring.
+
+<P>
+"You're all right," Tom assured her, as she came up, gasping,
+choking and crying hysterically. "You're all right!"
+
+<P>
+"Is--is Minnie saved?" she sobbed.
+
+<P>
+"Yes, Grace! I'm here," answered the one Ned was supporting.
+
+<P>
+"Oh, wasn't it terrible!" cried the second girl Tom had saved.
+
+<P>
+"I thought we would be drowned, even though we can swim."
+
+<P>
+"Yes, it--it was so--so sudden!" gasped her companion. "What
+happened?"
+
+<P>
+"The wash from that big boat upset you," explained Tom. "That
+fellow ought to be ashamed of himself, rushing along the way he
+did. Now, can I take you girls anywhere? Your canoe seems to have
+drifted off."
+
+<P>
+"I have it!" someone called. "It's turned over, but I can tow it
+to shore."
+
+<P>
+"And I'll take the girls home," offered a gentleman in a large
+rowboat. "My wife will look after them. They live near us," and he
+mentioned his own name and the names of the two girls Tom had
+saved. The young inventor did not know them, but he introduced
+himself and Ned.
+
+<P>
+"This is the annual moonlight outing of our little boat club,"
+explained the man who had offered to look after the girls, "and it
+is the first time we ever had an accident. This was not our fault,
+though."
+
+<P>
+"Indeed it was not," agreed Tom, after he had helped the two
+dripping young ladies into the rowboat. "It was due to Mr.
+Peters's speed mania."
+
+<P>
+"I shall make a complaint against him to the navigation
+authorities," said Mr. Ralston, who was looking after the girls.
+"He must think he, alone, has any rights on this lake."
+
+<P>
+With renewed thanks to Tom and Ned, the rescued girls were rowed
+off to their homes, while the interrupted water carnival was
+continued.
+
+<P>
+"Some little excitement; eh, Tom?" remarked Ned, when they were
+once more under way.
+
+<P>
+"Yes. We seem to run into that fellow Peters, or some of his
+doings, quite often lately."
+
+<P>
+"And it isn't a good sign, either," murmured Ned.
+
+<P>
+For some minutes after that Tom did not speak. In fact he was so
+silent that Ned at last inquired:
+
+<P>
+"What's the matter, Tom--in love?"
+
+<P>
+"Far from it. But, Ned, I've got an idea."
+
+<P>
+"And I've got a wet suit of clothes where that nice young lady
+fainted in my arms. I'm soaked."
+
+<P>
+"That's what gave me the idea--the water, I mean. I noticed how
+everything was reflected in it, and, do you know, Ned, I believe I
+have been working on the wrong principle for my photo telephone."
+
+<P>
+"Wrong, Tom, how is that?"
+
+<P>
+"Why, I've been using a dry plate, and I think I should have used
+a wet one. You know how even in a little puddle of water on the
+sidewalk you can see yourself reflected?"
+
+<P>
+"Yes, I've often seen that."
+
+<P>
+"Well then, 'bless my watch chain!' as Mr. Damon would say, I
+think I've got just what I want. I'm going to try a wet plate now,
+and I think it will work. Come on now. Speed up! I'm in a great
+big hurry to get home and try it!"
+
+<P>
+"Well, Tom, I sure will be glad if you've got the right idea,"
+laughed Ned. "It will be worth getting wet through for, if you
+strike something. Good luck!"
+
+<P>
+Tom could hardly wait to fasten up his boat for the night, so
+eager was he to get to his shop laboratory and try the new idea. A
+gleam of hope had come to him.
+
+<P>
+It was still early evening, and Tom, when enticed out by Ned, had
+left his photo telephone apparatus in readiness to go on with his
+trials as soon as he should have come back.
+
+<P>
+"Now for it, Ned!" exclaimed the young inventor, as he took off
+his coat. "First I'll sensitize a selenium plate, and then I'll
+wet it. Water is always a good conductor of electricity, and it's
+a wonder that I forgot that when I was planning this photo
+telephone. But seeing the sparkle of lights, and the reflection of
+ourselves in the lake to-night, brought it back to me. Now then,
+you haven't anything special to do; have you?"
+
+<P>
+"Not a thing, Tom."
+
+<P>
+"That's good. Then you get in this other telephone closet--the one
+in the casting shop. I'll put a prepared plate in there, and one
+in the booth where I'm to sit. Then I'll switch on the current,
+and we'll see if I can make you out, and you notice whether my
+image appears on your plate."
+
+<P>
+It took some little time to make ready for this new test. Tom was
+filled with enthusiasm, and he was sure it was going to be
+successful this time. Ned watched him prepare the selenium plates
+--plates that were so sensitive to illumination that, in the dark,
+the metal would hardly transmit a current of electricity, but in
+the light would do so readily, its conductivity depending on the
+amount of light it received.
+
+<P>
+"There, I guess we're all ready, Ned," announced Tom, at last.
+"Now you go to your little coop, and I'll shut myself up in mine.
+We can talk over the telephone."
+
+<P>
+Seated in the little booth in one of the smaller of Tom's shops,
+Ned proceeded with his part in the new experiment. A small shelf
+had been fitted up in the booth, or closet, and on this was the
+apparatus, consisting of a portable telephone set, and a small
+box, in which was set a selenium plate. This plate had been wet by
+a spray of water in order to test Tom's new theory.
+
+<P>
+In a similar booth, several hundred feet away, and in another
+building, Tom took his place. The two booths were connected by
+wires, and in each one was an electric light.
+
+<P>
+"All ready, Ned?" asked Tom, through the telephone.
+
+<P>
+"All ready," came the answer.
+
+<P>
+"Now then, turn on your switch--the one I showed you--and look
+right at the sensitized plate. Then turn out your light, and
+slowly turn it on. It's a new kind, and the light comes up
+gradually, like gas or an oil lamp. Turn it on easily."
+
+<P>
+"I get you, Tom."
+
+<P>
+Ned did as requested. Slowly the illumination in the booth
+increased.
+
+<P>
+"Do you get anything, Tom?" asked Ned, over the wire.
+
+<P>
+"Not yet," was the somewhat discouraged answer. "Go ahead, turn on
+more light, and keep your face close to the plate."
+
+<P>
+Ned did so.
+
+<P>
+"How about it now?" he asked, a moment later.
+
+<P>
+"Nothing--yet," was the answer. And then suddenly Tom's voice rose
+to a scream over the wire.
+
+<P>
+"Ned--Ned! Quick!" he called. "Come here--I--I--"
+
+<P>
+The voice died off into a meaningless gurgle.
+
+
+

+<H3>Chapter X Midnight Visitors</H3>
+
+
+<P>
+Ned Newton never knew exactly how he got out of the telephone
+booth. He seemed to give but one jump, tearing the clamped
+receiver from his ear, and almost upsetting the photo apparatus in
+his mad rush to help Tom. Certain it is, however, that he did get
+out, and a few seconds later he was speeding toward the shop where
+Tom had taken his position in a booth.
+
+<P>
+Ned burst in, crying out:
+
+<P>
+"Tom! What is it? What happened? What's the matter?"
+
+<P>
+There was no answer. Fearing the worst, Ned hurried to the small
+booth, in one corner of the big, dimly lighted shop. He could see
+Tom's lamp burning in the telephone compartment,
+
+<P>
+"Tom! Tom!" called the young banker.
+
+<P>
+Still there was no answer, and Ned, springing forward, threw open
+the double, sound-proof door of the booth. Then he saw Tom lying
+unconscious, with his head and arms on the table in front of him,
+while the low buzzing of the electrical apparatus in the
+transmitting box told that the current had not been shut off.
+
+<P>
+"Tom! Tom!" cried Ned in his chum's ear He shook him by the
+shoulder,
+
+<P>
+"Are you hurt? What is the matter?"
+
+<P>
+The young inventor seemed unconscious, and for a moment Ned had a
+wild idea that Tom had been shocked to death, possibly by some
+crossed live wire coming in contact with the telephone circuit.
+
+<P>
+"But that couldn't have happened, or I'd have been shocked
+myself," mused Ned.
+
+<P>
+Then he became aware of a curious, sweet, sickish odor in the
+booth. It was overpowering. Ned felt himself growing dizzy.
+
+<P>
+"I have it--chloroform!" he gasped. "In some way Tom has been
+overcome by chloroform. I've got to get him to the fresh air."
+
+<P>
+Once he had solved the puzzle of Tom's unconsciousness, Ned was
+quick to act. He caught Tom under the arms, and dragged him out of
+the booth, and to the outer door of the shop. Almost before Ned
+had reached there with his limp burden, Tom began to revive, and
+soon the fresh, cool night air completed the work.
+
+<P>
+"I--I," began the young inventor. "Ned, I--I--"
+
+<P>
+"Now take it easy, Tom," advised his chum. "You'll be all right in
+a few minutes. What happened? Shall I call your father, or Koku?"
+
+<P>
+"No--don't. It would only--only alarm dad," faltered Tom. "I'm
+getting all right now. But he--he nearly had me, Ned!"
+
+<P>
+"He had you? What do you mean, Tom? Who had you?"
+
+<P>
+"I don't know who it was, but when I was talking to you over the
+wire, all of a sudden I felt a hand behind me. It slipped over my
+mouth and nose, and I smelled chloroform. I knew right away
+something was wrong, and I called to you. That's all I remember. I
+guess I must have gone off."
+
+<P>
+"You did," spoke Ned. "You were unconscious when I got to you. I
+couldn't imagine what had happened. First I thought it was an
+electrical shock. Then I smelled that chloroform. But who could it
+have been, Tom?"
+
+<P>
+"Give it up, Ned! I haven't the slightest idea."
+
+<P>
+"Could they have been going to rob you?"
+
+<P>
+"I haven't a thing but a nickel watch on me," went on Tom. "I left
+all my cash in the house. If it was robbery, it wasn't me,
+personally, they were after."
+
+<P>
+"What then? Some of your inventions?"
+
+<P>
+"That's my idea now, Ned. You remember some years ago Jake Burke
+and his gang held me up and took one of dad's patents away from
+me?"
+
+<P>
+"Yes, I've heard you mention that. It was when you first got your
+motor cycle; wasn't it?"
+
+<P>
+"That's right. Well, what I was going to say was that they used
+chloroform on me then, and--"
+
+<P>
+"You think this is the same crowd? Why, I thought they were
+captured."
+
+<P>
+"No, they got away, but I haven't heard anything of them in years.
+Now it may be they have come back for revenge, for you know we got
+back the stolen property."
+
+<P>
+"That's right. Say, Tom, it might be so. What are you going to do
+about it?"
+
+<P>
+"I hardly know. If it was Jake Burke, alias Happy Harry, and his
+crowd, including Appleson, Morse and Featherton, they're a bad
+lot. I wouldn't want father to know they were around, for he'd be
+sure to worry himself sick. He never really got over the time they
+attacked me, and got the patent away. Dad sure thought he was
+ruined then."
+
+<P>
+"Now if I tell him I was chloroformed again to-night, and that I
+think it was Burke and his crowd, he'd be sure to get ill over it.
+So I'm just going to keep mum."
+
+<P>
+"Well, perhaps it's the best plan. But you ought to do something."
+
+<P>
+"Oh, I will, Ned, don't worry about that. I feel much better now."
+
+<P>
+"How did it happen?" asked Ned, his curiosity not yet satisfied.
+
+<P>
+"I don't know, exactly. I was in the booth, talking to you, and
+not paying much attention to anything else. I was adjusting and
+readjusting the current, trying to get that image to appear on the
+plate. All at once, I felt someone back of me, and, before I could
+turn, that hand, with the chloroform sponge, was over my mouth and
+nose. I struggled, and called out, but it wasn't much use."
+
+<P>
+"But they didn't do anything else--they didn't take anything; did
+they, Tom?"
+
+<P>
+"I don't know, Ned. We'll have to look around. They must have
+sneaked into the shop. I left the door open, you see. It would
+have been easy enough."
+
+<P>
+"How many were there?"
+
+<P>
+"I couldn't tell. I only felt one fellow at me; but he may have
+had others with him."
+
+<P>
+"What particular invention were they after, Tom?"
+
+<P>
+"I'm sure I don't know. There are several models in here that
+would be valuable. I know one thing, though, they couldn't have
+been after my photo telephone," and Tom laughed grimly.
+
+<P>
+"Why not?" Ned wanted to know.
+
+<P>
+"Because it's a failure--that's what! It's a dead, sure failure,
+Ned, and I'm going to give it up!" and Tom spoke bitterly.
+
+<P>
+"Oh, don't say that!" urged his chum. "You may be right on the
+verge of perfecting it, Tom. Didn't you see any image at all on
+the plate?"
+
+<P>
+"Not a shadow. I must be on the wrong track. Well, never mind
+about that now. I'm going to look around, and see if those fellows
+took anything."
+
+<P>
+Tom was feeling more like himself again, the effects of the
+chloroform having passed away. He had breathed the fumes of it for
+only a little while, so no harm had been done. He and Ned made an
+examination of the shop, but found nothing missing.
+
+<P>
+There were no traces of the intruders, however, though the two
+chums looked carefully about outside the building.
+
+<P>
+"You were too quick for them, Ned," said Tom. "You came as soon as
+I called. They heard me speaking, and must have known that I had
+given the alarm."
+
+<P>
+"Yes, I didn't lose any time," admitted Ned, "but I didn't see a
+sign of anyone as I ran up."
+
+<P>
+"They must have been pretty quick at getting away. Well, now to
+decide what's best to do to-night."
+
+<P>
+After some consultation and consideration it was decided to set
+the burglar alarms in every building of the Swift plant. Some time
+previous, when he had been working on a number of valuable
+inventions, unscrupulous men had tried to steal his ideas and
+models. To prevent this Tom had arranged a system of burglar
+alarms, and had also fitted up a wizard camera that would take
+moving pictures of anyone coming within its focus. The camera
+could be set to work at night, in connection with the burglar
+alarms.
+
+<P>
+The apparatus was effective, and thus an end was put to the
+efforts of the criminals. But now it seemed Tom would have to take
+new precautionary measures. His camera, however, was not
+available, as he had loaned it to a scientific society for
+exhibition.
+
+<P>
+"But we'll attach the burglar wires," decided Tom, "and see what
+happens."
+
+<P>
+"It might be a good plan to have Koku on guard," said Tom's chum.
+"That giant could handle four or five of the chaps as easily as
+you and I could tackle one."
+
+<P>
+"That's right," agreed Tom. "I'll put him on guard. Whew! That
+chloroform is giving me a headache. Guess I'll go to bed. I wish
+you'd stay over to-night, Ned, if you haven't anything else to do.
+I may need you."
+
+<P>
+"Then of course I'll stay, Tom. I'll telephone home that I won't
+be in."
+
+<P>
+A little later Tom had put away his new photo telephone apparatus,
+and had prepared for the warm reception of any unbidden callers.
+
+<P>
+"I wish I hadn't started on this new invention," said Tom, half
+bitterly, as he locked up the main parts of his machine, "I know
+it will never work."
+
+<P>
+"Oh, yes it will," spoke Ned, cheerfully. "You never failed yet,
+Tom Swift, in anything you undertook, and you're not going to
+now."
+
+<P>
+"Well, that's good of you to say, Ned, but I think you're wrong
+this time. But I'm not going to think any more about it to-night,
+anyhow. Now to find Koku and put him on watch."
+
+<P>
+The giant listened carefully to Tom's simple instructions.
+
+<P>
+"If any bad men come in the night, Koku," said the young inventor,
+"you catch them!"
+
+<P>
+"Yes, master, me catch!" said Koku, grimly. "Me catch!" and he
+stretched out his powerful arms, and clenched his big hands in a
+way that boded no good to evildoers.
+
+<P>
+Nothing was said to Mr. Swift, to Mrs. Baggert, or to Eradicate
+about what had happened, for Tom did not want to worry them. The
+burglar alarms were set, Koku took his place where he could watch
+the signals, and at the same time be ready to rush out, for,
+somehow, Tom had an idea that the men who had attacked him would
+come back.
+
+<P>
+Tom and Ned occupied adjoining rooms, and soon were ready for bed.
+But, somehow, Tom could not sleep. He lay awake, tossing from side
+to side, and, in spite of his resolution not to think about his
+photo telephone invention, his mind ran on nothing but that.
+
+<P>
+"I can't see what next to do to make it work," he told himself,
+over and over again. "Something is wrong--but what?"
+
+<P>
+At length he fell into a fitful doze, and he had a wild dream that
+he was sliding down hill on a big mirror in which all sorts of
+reflections were seen--reflections that he could not get to show
+in the selenium plates.
+
+<P>
+Then Tom felt the mirror bobbing up and down like a motor boat in
+a storm. He felt the vibration, and he heard a voice calling in
+his ear:
+
+<P>
+"Get up, Tom! Get up!"
+
+<P>
+"Yes! What is it?" he sleepily exclaimed,
+
+<P>
+"Hush!" was the caution he heard, and then he realized that his
+dream had been caused by Ned shaking him.
+
+<P>
+"Well?" whispered Tom, in tense tones.
+
+<P>
+"Midnight visitors!" answered his chum "The burglar alarm has just
+gone off! The airship hangar drop fell. Koku has gone out. Come
+on!"
+
+
+
+
+
+<P>
+<A NAME="XI"></A>
+<H3>Chapter XI The Airship Is Taken</H3>
+
+
+<P>
+Tom leaped silently out of bed, and stood for a moment half
+dazed, so soundly had he been sleeping.
+
+<P>
+"Come on!" urged Ned softly, realizing that his chum had not fully
+comprehended. "Koku will hold them until we get there. I haven't
+roused anyone else."
+
+<P>
+"That's right," whispered Tom, as he began putting on his clothes.
+"I don't want father to know. When did it happen?"
+
+<P>
+"Just a little while ago. I couldn't sleep very well, but I fell
+into a doze, and then I heard the buzzer of the alarm go off. I
+saw that the drop, showing that the hangar had been entered, had
+fallen. I got to the window in time to see Koku going toward the
+shed from his little coop. Then I came to you."
+
+<P>
+"Glad you did," answered Tom. "I didn't think I was sleeping so
+soundly."
+
+<P>
+Together the two chums made their way from their rooms down the
+dimly-lighted hall to a side door, whence they could reach the
+airship hangar, or shed.
+
+<P>
+"Won't we need something--a gun or--" began Ned.
+
+<P>
+"Clubs are better--especially at night when you can't see to aim
+very well," whispered back Tom. "I've got a couple of good ones
+downstairs. I could use my electric rifle, and set it merely to
+disable temporarily whoever the charge hit, but it's a little too
+risky. Koku has a habit of getting in the way at the most
+unexpected times. He's so big, you know. I think clubs will be
+best."
+
+<P>
+"All right, Tom, just as you say," agreed Ned. "But who do you
+think it can be?"
+
+<P>
+"I haven't the least idea. Probably the same fellows who were
+after me before, though. This time I'll find out what their game
+is, and what they're after."
+
+<P>
+The chums reached the lower hall, and there Tom picked out two
+African war clubs which he had brought back with him from one of
+his many trips into wild lands.
+
+<P>
+"These are just the thing!" exclaimed Ned, swinging his about.
+
+<P>
+"Careful," cautioned Tom, "If you hit something you'll rouse the
+house, and I don't want my father and Mrs. Baggert, to say nothing
+of Eradicate, awakened."
+
+<P>
+"Excuse me," murmured Ned. "But we'd better be getting a move on."
+
+<P>
+"That's right," agreed Tom. He dropped into a side pocket a small
+but powerful electric flash lamp, and then he and Ned let
+themselves out.
+
+<P>
+There had been a bright moon, but it was now overcast by clouds.
+However, there was sufficient light to enable the two lads to see
+objects quite clearly. All about them were the various buildings
+that made up the manufacturing and experimental plant of Tom Swift
+and his father. Farthest away from the house was the big shed
+where once Tom had kept a balloon, but which was now given over to
+his several airships. In front of it was a big, level grassy
+space, needed to enable the aircraft to get a "running start"
+before they could mount into the clouds.
+
+<P>
+"See anything of Koku?" whispered Ned.
+
+<P>
+"No," answered Tom, in the same cautious voice. "I guess he must
+be hiding--"
+
+<P>
+"There he goes now!" hissed Ned, pointing to a big figure that was
+approaching the hangar. It was undoubtedly that of the giant, and
+he could be seen, in the dim light, stalking cautiously along.
+
+<P>
+"I wonder where the uninvited guests are?" asked Tom.
+
+<P>
+"Probably in the airship shed," answered Ned. "Koku was after them
+as soon as the alarm went off, and they couldn't have gotten away.
+They must be inside there yet. But what can their game be?"
+
+<P>
+"It's hard to say," admitted Tom. "They may be trying to get
+something belonging to me, or they may imagine they can pick up
+some valuable secrets. Or they may--" He stopped suddenly, and
+then exclaimed:
+
+<P>
+"Come on, Ned! They're after one of the airships! That's it! My
+big biplane is all ready to start, and they can get it in motion
+inside of a few seconds. Oh, why didn't I hurry?" he added,
+bitterly.
+
+<P>
+But the hangar was still some distance away, and it would take two
+or three minutes of running to reach it.
+
+<P>
+Meanwhile, and at the instant Tom had his thought of the possible
+theft of his biggest aircraft, something happened.
+
+<P>
+The doors of the shed were suddenly thrown open, and the two boys
+could see the large airship being wheeled out. The hazy light of
+the moon behind the clouds shone on the expanse of white planes,
+and on the fish-tail rudder, one of Tom's latest ideas.
+
+<P>
+"Hey, there!" cried Tom, warningly.
+
+<P>
+"Leave that alone!" yelled Ned.
+
+<P>
+"Koku! Koku!" shouted Tom, shrilly. "Get after those fellows!"
+
+<P>
+"Me get!" boomed out the giant, in his deep voice.
+
+<P>
+He had been standing near the entrance to the hangar, probably
+waiting for developments, and watching for the arrival of Tom and
+Ned. The big form was seen to leap forward, and then several dark
+shadows swarmed from around the airship, and were seen to fling
+themselves upon the giant.
+
+<P>
+"That's a fight!" cried Ned. "They're attacking him!"
+
+<P>
+"Koku can take care of himself!" murmured Tom. "But come on. I
+don't see what their game is."
+
+<P>
+He understood a moment later, however, for while several of the
+midnight visitors were engaged in a hand-to-hand tussle with the
+giant there came a sharp, throbbing roar of the airship motor in
+motion. The propellers were being whirled rapidly about.
+
+<P>
+"Koku! Koku!" cried Tom, for he was still some distance off.
+"Never mind them! Don't let the airship be taken!"
+
+<P>
+But Koku could only grunt. Big and strong as he was, half a dozen
+men attacking him at once hampered him. He threw them from him,
+one after another, and was gradually making his way toward the now
+slowly-moving airship. But would he be in time?
+
+<P>
+Tom and Ned could not hope to reach the machine before Koku,
+though they were running at top speed.
+
+<P>
+"Koku! Koku!" yelled Tom. "Don't let them get away!"
+
+<P>
+But Koku could only grunt--harder this time--for he fell heavily,
+being tripped by a stick thrust between his legs. He lay for a
+moment stunned.
+
+<P>
+"They're going to get away!" panted Tom, making an effort to
+increase his speed.
+
+<P>
+"That's what!" agreed Ned.
+
+<P>
+Even as they spoke the roar of the airship motor increased.
+Several of the dark forms which had been engaged in the struggle
+with Koku were seen to pick themselves up, and run toward the
+airship, that was now in motion, moving on the bicycle wheels over
+the grass plot, preparatory to mounting upward in the sky.
+
+<P>
+"Stop! Stop!" commanded Tom. But it was all in vain.
+
+<P>
+The men leaped aboard the airship, which could carry six persons,
+and a moment later, with a deafening roar, as the engine opened up
+full, the big craft shot upward, taking away all but two of the
+midnight visitors. These, who had seemingly been stunned by Koku,
+now arose from the ground, and staggered off in the darkness.
+
+<P>
+"Get them!" cried Tom.
+
+<P>
+"We must see to Koku!" added Ned, "Look, there goes your airship,
+Tom!"
+
+<P>
+"Yes, I know. But we can't stop that now. Let's see if we can get
+a clew in these fellows!"
+
+<P>
+He pointed toward the two who had run off in the dark underbrush
+surrounding the hangar plaza, and he and Ned trailed them as well
+as they could. But from the first they knew it would be useless,
+for there were many hiding places, and, a little way beyond, was a
+clump of trees.
+
+<P>
+After a short search Tom gave up reluctantly, and came back to
+where Koku was now sitting on the ground.
+
+<P>
+"Are you hurt?" he asked of the giant.
+
+<P>
+"My mind hurt--that all," said the big man.
+
+<P>
+"I guess he means his feelings are hurt," Tom explained. "Do you
+know who they were, Koku?"
+
+<P>
+"No, master."
+
+<P>
+"But we must do something!" cried Ned. "They've got your airship,
+Tom."
+
+<P>
+"I know it," said the young inventor, calmly. "But we can't do
+anything now. You can hardly hear her, let alone see her. She's
+moving fast!"
+
+<P>
+He pointed upward to the darkness. Like some black bird of prey
+the airship was already lost to sight, though it would have seemed
+as if her white planes might render her visible. But she had moved
+so swiftly that, during the short search, she had already
+disappeared.
+
+<P>
+"Aren't you going to do anything?" asked Ned.
+
+<P>
+"Certainly," spoke Tom. "I'm going to telephone an alarm to all
+the nearby towns. This is certainly a queer game, Ned."
+
+
+
+
+
+<P>
+<A NAME="XII"></A>
+<H3>Chapter XII A Strange Disappearance</H3>
+
+
+<P>
+Disappointed and puzzled, Tom and Ned went to where Koku was
+standing in rather a dazed attitude. The giant, like all large
+bodies, moved slowly, not only bodily but mentally. He could
+understand exactly what had happened, except that he had not
+prevailed over the "pygmies" who had attacked him. They had been
+too many for him.
+
+<P>
+"Let's take a look inside," suggested Tom, when, by another glance
+upward, he had made sure that all trace of his big airship was
+gone. "Maybe we can get a clew. Then, Koku, you tell us what
+happened."
+
+<P>
+"It all happened to me," said the giant, simply. "Me no make
+anything happen to them."
+
+<P>
+"That's about right," laughed Tom, ruefully. "It all happened to
+us."
+
+<P>
+The lights in the hangar were switched on, but a careful search
+revealed little. The men, half a dozen or more, had come evidently
+well prepared for the taking away of Tom Swift's airship, and they
+had done so.
+
+<P>
+Entrance had been effected by forcing a small side door. True, the
+burglar alarm had given notice of the presence of the men, but Tom
+and Ned had not acted quite quickly enough. Koku had been at the
+hangar almost as soon as the men themselves, but he had watched
+and waited for orders, instead of going in at once, and this had
+given the intruders time to wheel out the craft and start the
+motor.
+
+<P>
+"Why didn't you jump right in on them when you saw what they were
+up to, Koku?" asked Tom.
+
+<P>
+"Me wait for master. Me think master want to see who men were. Me
+go in--they run."
+
+<P>
+"Well, of course that's so, in a way," admitted Tom. "They
+probably would have run, but they'd have run <i>without</i> my airship
+instead of <i>with</i> it, if they hadn't had time to get it outside the
+hangar. However, there's no use in crying over lost biplanes. The
+next thing is how to get her back. Did you know any of the men,
+Koku?"
+
+<P>
+"No, master."
+
+<P>
+"Then we haven't any clew that way. They laid their plans well.
+They just let you tangle yourself up with them, Koku, while the
+head ones got the motor going; an easy matter, since it was all
+ready to start. Then they tripped you, Koku, and as many of them
+as could, made a jump for the machine. Then they were off."
+
+<P>
+"Well, what's the next thing to do?" asked Ned, when another look
+about the shed had shown that not the slightest clew was
+available.
+
+<P>
+"I'm going to do some telephoning," Tom stated. "A big airship
+like mine can't go scooting around the country without being
+noticed. And those fellows can't go on forever. They've got to
+have gasolene and oil, and to get them they'll have to come down.
+I'll get it back, sooner or later; but the question is: Why did
+they take her?"
+
+<P>
+"To sell," suggested Ned.
+
+<P>
+"I think not," Tom said. "A big airship like mine isn't easy to
+sell. People who would buy it would ask questions that might not
+easily be answered. I'm inclined to think that some other reason
+made them take her, and it's up to us to find out what it was.
+Let's go into the house."
+
+<P>
+"Hark!" suddenly exclaimed Ned, holding up his hand for silence.
+They all heard footsteps outside the hangar.
+
+<P>
+Tom sprang to the door, flashing his electric light, and a voice
+exclaimed:
+
+<P>
+"Golly! Chicken thieves!"
+
+<P>
+"Oh, is it you, Eradicate?" asked the young inventor, with a
+laugh. "No, it isn't chicken thieves--they were after bigger game
+this time."
+
+<P>
+"Suffin happen?" asked the colored man. "Massa Swift he heah a
+noise, an' see a light, an' he sent me out yeah t' see what all am
+gwine on."
+
+<P>
+"Yes, something happened," admitted Tom. "They got the <i>Eagle</i>,
+Rad."
+
+<P>
+"What! Yo' big airship?"
+
+<P>
+"Yes."
+
+<P>
+"Huh! Dat's too bad, Massa Tom. I suah am sorry t' heah dat. Who
+done it?"
+
+<P>
+"We don't know, Rad."
+
+<P>
+"Maybe it was dat low-down cousin ob mine what tried t' git mah
+chickens, onct!"
+
+<P>
+"No, Rad, it wasn't your cousin. But I'll telephone the alarm to
+the police. They may be able to help me get the <i>Eagle</i> back."
+
+<P>
+Within the next hour several messages were sent to the authorities
+of nearby towns, asking them to be on the watch for the stolen
+airship. This was about all that could be done, and after Mr.
+Swift had been told the story of the night's happenings, everyone
+went back to bed again.
+
+<P>
+Further search the next morning brought forth no clews, though
+Tom, Ned and the others beat about in the bushes where the men had
+disappeared.
+
+<P>
+One or two reports were heard from surrounding towns, to the
+effect that several persons had heard a strange throbbing sound in
+the night, that, possibly, was caused by the passage of the
+airship overhead. One such report came from Waterford, the home
+town of Mr. Damon.
+
+<P>
+"Let's go over there," suggested Ned, to his chum. "I'd like to
+see our friend, and maybe we can get some other clews by
+circulating around there."
+
+<P>
+"Oh, I don't know," spoke Tom, rather listlessly.
+
+<P>
+"Why not?" Ned wanted to know.
+
+<P>
+"Well, I ought to be working on my photo telephone," was the
+answer. "I've got a new idea now. I'm going to try a different
+kind of current, and use a more sensitive plate. And I'll use a
+tungsten filament lamp in the sending booth."
+
+<P>
+"Oh, let your experiments go for a little while, Tom," suggested
+Ned. "Come on over to Mr. Damon's. The trouble with you is that
+you keep too long at a thing, once you start."
+
+<P>
+"That's the only way to succeed," remarked Tom. "Really, Ned,
+while I feel sorry about the airship, of course, I ought to be
+working on my telephone. I'll get the <i>Eagle</i> back sooner or later."
+
+<P>
+"That's not the way to talk, Tom. Let's follow up this clew."
+
+<P>
+"Well, if you insist on it I suppose I may as well go. We'll take
+the little monoplane. I've fixed her up to carry double. I guess--"
+
+<P>
+Tom Swift broke off suddenly, as the telephone at his elbow rang.
+
+<P>
+"Hello," he said, taking off the receiver. "Yes, this is Tom
+Swift. Oh, good morning, Mrs. Damon! Eh! What's that? Mr. Damon
+has disappeared? You don't tell me! Disappeared! Yes, yes, I can
+come right over. Be there in a few minutes. Eh? You don't know
+what to make of it? Oh, well, maybe it can easily be explained.
+Yes, Ned Newton and I will be right over. Don't worry."
+
+<P>
+Tom hung up the receiver and turned to his chum.
+
+<P>
+"What do you think of that?" he asked.
+
+<P>
+"What is it?"
+
+<P>
+"Why, Mr. Damon mysteriously vanished last night, and this morning
+word came from his bankers that every cent of his fortune had
+disappeared! He's lost everything!"
+
+<P>
+"Maybe--maybe--" hesitated Ned.
+
+<P>
+"No, Mr. Damon isn't that kind of a man," said Tom, stoutly. "He
+hasn't made away with himself."
+
+<P>
+"But something is wrong!"
+
+<P>
+"Evidently, and it's up to us to find out what it is. I shouldn't
+be surprised but that he knew of this coming trouble and started
+out to prevent it if he could."
+
+<P>
+"But he wouldn't disappear and make his wife worry."
+
+<P>
+"No, that's so. Well, we'll have to go over there and find out all
+about it."
+
+<P>
+"Say, Tom!" exclaimed Ned, as they were getting the small, but
+swift monoplane ready for the flight, "could there be any
+connection with the disappearance of Mr. Damon and the taking of
+the <i>Eagle</i>?"
+
+<P>
+Tom started in surprise.
+
+<P>
+"How could there be?" he asked.
+
+<P>
+"Oh, I don't know," answered Ned. "It was only an idea."
+
+<P>
+"Well, we'll see what Mrs. Damon has to say," spoke the young
+inventor, as he took his seat beside Ned, and motioned to Koku to
+twirl the propeller.
+
+
+
+
+
+<P>
+<A NAME="XIII"></A>
+<H3>Chapter XIII The Telephone Picture</H3>
+
+
+<P>
+"Oh, Tom Swift! I'm so glad to see you!"
+
+<P>
+Mrs. Damon clasped her arms, in motherly fashion, about the young
+inventor. He held her close, and his own eyes were not free from
+tears as he witnessed the grief of his best friend's wife.
+
+<P>
+"Now, don't worry, Mrs. Damon," said Tom, sympathetically.
+"Everything will be all right," and he led her to a chair.
+
+<P>
+"All right, Tom! How can it be?" and the lady raised a tear-stained
+face. "My husband has disappeared, without a word! It's
+just as if the earth had opened and swallowed him up! I can't find
+a trace of him! How can it be all right?"
+
+<P>
+"Well, we'll find him, Mrs. Damon. Don't worry. Ned and I will get
+right to work, and I'll have all the police and detectives within
+fifty miles on the search--if we have to go that far."
+
+<P>
+"Oh, it's awfully good of you, Tom. I--I didn't know who else to
+turn to in my trouble but you."
+
+<P>
+"And why shouldn't you come to me? I'd do anything for you and Mr.
+Damon. Now tell me all about it."
+
+<P>
+Tom and Ned had just arrived at the Damon home in the airship, to
+find the wife of the eccentric man almost distracted over her
+husband's strange disappearance.
+
+<P>
+"It happened last night," Mrs. Damon said, when she was somewhat
+composed. "Last night about twelve o'clock."
+
+<P>
+"Twelve o'clock!" cried Tom, in surprise "Why that's about the
+time--"
+
+<P>
+He stopped suddenly.
+
+<P>
+"What were you going to say?" asked Mrs. Damon.
+
+<P>
+"Oh--nothing," answered Tom. "I--I'll tell you later. Go on,
+please."
+
+<P>
+"It is all so confusing," proceeded Mrs. Damon. "You know my
+husband has been in trouble of late--financial trouble?"
+
+<P>
+"Yes," responded Tom, "he mentioned it to me."
+
+<P>
+"I don't know any of the details," sighed Mrs. Damon, "but I know
+he was mixed up with a man named Peters."
+
+<P>
+"I know him, too," spoke Tom, grimly.
+
+<P>
+"My husband has been very gloomy of late," went on Mrs. Damon. "He
+foolishly entrusted almost his entire fortune to that man, and
+last night he told me it was probably all gone. He said he saw
+only the barest chance to save it, but that he was going to take
+that chance."
+
+<P>
+"Did he go into details?" asked Tom.
+
+<P>
+"No, that was all he said. That was about ten o'clock. He didn't
+want to go to bed. He just sat about, and he kept saying over and
+over again: 'Bless my tombstone!' 'Bless the cemetery!' and all
+such stuff as that. You know how he was," and she smiled through
+her tears.
+
+<P>
+"Yes," said Tom. "I know. Only it wasn't like him to bless such
+grewsome things. He was more jolly."
+
+<P>
+"He hasn't been, of late," sighed his wife. "Well, he sat about
+all the evening, and he kept figuring away, trying, I suppose, to
+find some way out of his trouble."
+
+<P>
+"Why didn't he come to my father?" cried Tom. "I told him he could
+have all the money he needed to tide him over."
+
+<P>
+"Well, Mr. Damon was queer that way," said his wife. "He wanted to
+be independent. I urged him to call you up, but he said he'd fight
+it out alone."
+
+<P>
+"As I said, we sat there, and he kept feeling more and more blue,
+and blessing his funeral, and the hearse and all such things as
+that. He kept looking at the clock, too, and I wondered at that."
+
+<P>
+"'Are you expecting someone?' I asked him. He said he wasn't,
+exactly, but I made sure he was, and finally, about half-past
+eleven, he put on his hat and went out."
+
+<P>
+"'Where are you going?' I asked him."
+
+<P>
+"'Oh, just to get a breath of air. I can't sleep,' he said. I
+didn't think much of that, as he often used to go out and walk
+about a bit before going to bed. So he went out, and I began to
+see about locking up, for I never trust the servants."
+
+<P>
+"It must have been about an hour later when I heard voices out in
+front. I looked, and I saw Mr. Damon talking to a man."
+
+<P>
+"Who was he?" asked Tom, eagerly, on the alert for the slightest
+clew.
+
+<P>
+"I thought at the time," said Mrs. Damon, "that it was one of the
+neighbors. I have learned since, however, that it was not. Anyhow,
+this man and Mr. Damon stood talking for a little while, and then
+they went off together. I didn't think it strange at the time,
+supposing he was merely strolling up and down in front with Mr.
+Blackson, who lives next door, He often had done that before."
+
+<P>
+"Well, I saw that the house was locked up, and then I sat down in
+a chair to wait for Mr. Damon to come back. I was getting sleepy,
+for we don't usually stay up so late. I suppose I must have dozed
+off, but I was suddenly awakened by hearing a peculiar noise. I
+sat up in alarm, and then I realized that Mr. Damon had not come
+in."
+
+<P>
+"I was frightened then, and I called my maid. It was nearly one
+o'clock, and my husband never stays out as late as that. We went
+next door, and found that Mr. Blackson had not been out of his
+house that evening. So it could not have been he to whom Mr. Damon
+was speaking."
+
+<P>
+"We roused up other neighbors, and they searched all about the
+grounds, thinking he might have been overcome by a sudden faint. But
+we could not find him. My husband had disappeared--mysteriously
+disappeared!" and the lady broke into sobs.
+
+<P>
+"Now don't worry," said Tom, soothingly, as he put his arms about
+her as he would have done to his own mother, had she been alive,
+"We'll get him back!"
+
+<P>
+"But how can you? No one knows where he is."
+
+<P>
+"Oh, yes!" said Tom, confidently, "Mr. Damon himself knows where
+he is, and unless he has gone away voluntarily, I think you will
+soon hear from him."
+
+<P>
+"What do you mean by--voluntarily?" asked the wife.
+
+<P>
+"First let me ask you a question," came from Tom. "You said you
+were awakened by a peculiar noise. What sort of a sound was it?"
+
+<P>
+"Why, a whirring, throbbing noise, like--like--"
+
+<P>
+She paused for a comparison.
+
+<P>
+"Like an airship?" asked Tom, with a good deal of eagerness.
+
+<P>
+"That was it!" cried Mrs. Damon. "I was trying to think where I
+had heard the sound before. It was just like the noise your
+airship makes, Tom!"
+
+<P>
+"That settles it!" exclaimed the young inventor.
+
+<P>
+"Settles what?" asked Ned.
+
+<P>
+"The manner of Mr. Damon's disappearance. He was taken away--or
+went away--in my airship--the airship that was stolen from my shed
+last night!"
+
+<P>
+Mrs. Damon stared at Tom in amazement.
+
+<P>
+"Why--why--how could that be?" she asked.
+
+<P>
+Quickly Tom told of what had happened at his place.
+
+<P>
+"I begin to see through it," he said. "There is some plot here,
+and we've got to get to the bottom of it. Mr. Damon either went
+with these men in the airship willingly, or he was taken away by
+force. I'm inclined to think he went of his own accord, or you
+would have heard some outcry, Mrs. Damon."
+
+<P>
+"Well, perhaps so," she admitted. "But would he go away in that
+manner without telling me?"
+
+<P>
+"He might," said Tom, willing to test his theory on all sides. "He
+might not have wanted you to worry, for you know you dislike him
+to go up an airships."
+
+<P>
+"Yes, I do. Oh, if I only thought he did go away of his own
+accord, I could understand it. He went, if he did, to try and save
+his fortune."
+
+<P>
+"It does look as though he had an appointment with someone, Tom,"
+suggested Ned. "His looking at the clock, and then going out, and all
+that."
+
+<P>
+"Yes," admitted the young inventor, "and now I'm inclined to
+change my theory a bit. It may have been some other airship than
+mine that was used."
+
+<P>
+"How so?" asked Ned.
+
+<P>
+"Because the men who took mine were unprincipled fellows. Mr.
+Damon would not have gone away with men who would steal an
+airship."
+
+<P>
+"Not if he knew it," admitted Ned. "Well, then, let's consider two
+airships--yours and the other that came to keep the appointment
+with Mr. Damon. If the last is true, why should he want to go away
+in an airship at midnight? Why couldn't he take a train, or an
+auto?"
+
+<P>
+"Well, we don't know all the ins and outs," admitted Tom. "Taking
+a midnight airship ride is rather strange, but that may have been
+the only course open. We'll have to let the explanation go until
+later. At any rate, Mrs. Damon, I feel sure that your husband did
+go off through the air--either in my <i>Eagle</i> or in some other
+craft."
+
+<P>
+"Well, I'm glad to hear you say so, Tom Swift, though it sounds a
+dreadful thing to say. But if he did go off of his own accord, I
+know he did it for the best. And he may not have told me, for fear
+I would worry. I can understand that. But why isn't he back now?"
+
+<P>
+Tom had been rather dreading that question. It was one he had
+asked himself, and he had found no good answer for it. If there
+had been such need of haste, that an airship had to be used. why
+had not Mr. Damon come back ere this? Unless, as Tom feared to
+admit, even to himself, there had been some accident.
+
+<P>
+Half a dozen theories flashed through his mind, but he could not
+select a good, working one,--particularly as there were no clews.
+Disappearing in an airship was the one best means of not leaving a
+trace behind. An auto, a motor boat, a train, a horse and
+carriage--all these could be more or less easily traced. But an
+airship--
+
+<P>
+If Mr. Damon wanted to cover up his tracks, or if he had been
+taken away, and his captors wanted to baffle pursuit, the best
+means had been adopted.
+
+<P>
+"Now don't you worry," advised Tom to Mrs. Damon. "I know it looks
+funny, but I think it will come out all right. Ned and I will do
+all we can. Mr. Damon must have known what he was about. But, to
+be on the safe side, we'll send out a general alarm through the
+police."
+
+<P>
+"Oh, I don't know what I'd done if you hadn't come to help me!"
+exclaimed Mrs. Damon.
+
+<P>
+"Just you leave it to me!" said the young inventor, cheerfully.
+"I'll find Mr. Damon!"
+
+<P>
+But, though he spoke thus confidently, Tom Swift had not the
+slightest notion, just then, of how to set about his difficult
+task. He had had hard problems to solve before, so he was not
+going to give up this one. First he wanted to think matters out,
+and arrange a plan of action.
+
+<P>
+He and Ned made a careful examination of the grounds of the Damon
+homestead. There was little they could learn, though they did find
+where an airship had landed in a meadow, not far away, and where
+it had made a flying start off again.
+
+<P>
+Carefully Tom looked at the marks made by the wheels of the
+airship.
+
+<P>
+"They're the same distance apart as those on the <i>Eagle</i>," he said
+to his chum, "and the tires are the same. But that isn't saying
+anything, as lots of airships have the same equipment. So we won't
+jump to any conclusions that way."
+
+<P>
+Tom and Ned interviewed several of the neighbors, but beyond
+learning that some of them had heard the throbbing of the midnight
+airship, that was as far as they got on that line.
+
+<P>
+There was nothing more they could do in Waterford, and, leaving
+Mrs. Damon, who had summoned a relative to stay with her, the two
+chums made a quick trip back through the air to Shopton. As
+Eradicate came out to help put away the monoplane Tom noticed that
+the colored man was holding one hand as though it hurt him.
+
+<P>
+"What's the matter, Rad?" asked the young investor.
+
+<P>
+"Oh, nuffin--jest natcherly nuffin, Massa Tom."
+
+<P>
+But Eradicate spoke evasively and in a manner that roused Tom's
+suspicions.
+
+<P>
+"Boomerang, your mule, didn't kick you; did he?"
+
+<P>
+"No, sah, Massa Tom, no sah. 'Twern't nuffin laik dat."
+
+<P>
+"But what was it? Your hand is hurt!"
+
+<P>
+"Well, Massa Tom, I s'pose I done bettah tell yo' all. I'se had a
+shock!"
+
+<P>
+"A shock?"
+
+<P>
+"Yas, sah. A shock. A lickrish shock."
+
+<P>
+"Oh, you mean an electrical shock. That's too bad. I suppose you
+must have touched a live wire."
+
+<P>
+"No, sah. 'Twern't dat way."
+
+<P>
+"How was it, then?"
+
+<P>
+"Well, yo' see, Massa Tom, I were playin' a joke on Koku."
+
+<P>
+"Oh, you were; eh? Then I suppose Koku shocked you," laughed Tom.
+
+<P>
+"No, sah. I--I'll tell you. Dat giant man he were in de telefoam
+boof in de pattern shop--you know--de one where yo' all been
+tryin' to make pishures."
+
+<P>
+"Yes, I know. Go on!" exclaimed Tom, impatiently.
+
+<P>
+"Well, he were in dere, Massa Tom, an' I slipped into de boof in
+de next shop--de odder place where yo' all been 'speermentin'. I
+called out on de telefoam, loud laik de Angel Gabriel gwine t'
+holler at de last trump: 'Look out, yo' ole sinnah!' I yell it
+jest t' scare Koku."
+
+<P>
+"I see," said Tom, a bit severely, for he did not like Eradicate
+interfering with the instruments. "And did you scare Koku?"
+
+<P>
+"Oh, yas, sah, Massa Tom. I skeered him all right; but suffin else
+done happen. When I put down de telefoam I got a terrible shock.
+It hurts yit!"
+
+<P>
+"Well," remarked Tom, "I suppose I ought to feel sorry for you,
+but I can't. You should let things alone. Now I've got to see if
+you did any damage. Come along, Ned."
+
+<P>
+Tom was the first to enter the telephone booth where Eradicate had
+played the part of the Angel Gabriel. He looked at the wires and
+apparatus, but could see nothing wrong.
+
+<P>
+Then he glanced at the selenium plate, on which he hoped, some
+day, to imprint an image from over the wire. And, as he saw the
+smooth surface he started, and cried.
+
+<P>
+"Ned! Ned, come here quick!"
+
+<P>
+"What is it?" asked his chum, Crowding into the booth.
+
+<P>
+"Look at that plate! Tell me what you see!"
+
+<P>
+Ned looked.
+
+<P>
+"Why--why it's Koku's picture!" he gasped.
+
+<P>
+"Exactly!" cried Tom. "In some way my experiment has succeeded
+when I was away. Eradicate must have made some new connection by
+his monkeying. Ned, it's a success! I've got my first photo
+telephone picture! Hurray!"
+
+
+
+

+
+
+<P>
+Tom Swift was so overjoyed and excited that for a few moments he
+capered about, inside the booth, and outside, knocking against his
+chum Ned, clapping him on the back, and doing all manner of boyish
+"stunts."
+
+<P>
+"It's a success, Ned! I've struck it!" cried Tom, in delight.
+
+<P>
+"Ouch! You struck <i>me</i>, you mean!" replied Ned, rubbing his
+shoulder, where the young inventor had imparted a resounding blow
+of joy.
+
+<P>
+"What of it?" exclaimed Tom. "My apparatus works! I can send a
+picture by telephone! It's great, Ned!"
+
+<P>
+"But I don't exactly understand how it happened," said Ned, in
+some bewilderment, as he gazed at the selenium plate.
+
+<P>
+"Neither do I," admitted Tom, when he had somewhat calmed down.
+"That is, I don't exactly understand what made the thing succeed
+now, when it wouldn't work for me a little while ago. But I've got
+to go into that. I'll have to interview that rascal Eradicate, and
+learn what he did when he played that trick on Koku. Yes, and I'll
+have to see Koku, too. We've got to get at the bottom of this,
+Ned."
+
+<P>
+"I suppose so. You've got your hands full, Tom, with your photo
+telephone, and the disappearance of Mr. Damon."
+
+<P>
+"Yes, and my own airship, too. I must get after that. Whew! A lot
+of things to do! But I like work, Ned. The more the better."
+
+<P>
+"Yes, that's like you, Tom. But what are you going to get at
+first?"
+
+<P>
+"Let me see; the telephone, I think. I'll have Rad and Koku in
+here and talk to them. I say, you Eradicate!" he called out of the
+door of the shop, as he saw the colored man going past, holding
+his shocked arm tenderly.
+
+<P>
+"Yas, sah, Massa Tom, I'se comin'! What is it yo' all wants, Massa
+Tom?"
+
+<P>
+"I want you to show me exactly what you did to the wires, and
+other things in here, when you played that Angel Gabriel trick on
+your partner Koku."
+
+<P>
+"Partner! He ain't mah partner!" exclaimed Eradicate with a scowl,
+for there was not the best of feeling between the two. Eradicate
+had served in the Swift family many years, and he rather resented
+the coming of the giant, who performed many services formerly the
+province of the colored man.
+
+<P>
+"Well, never mind what he is, Rad," laughed Tom. "You just show me
+what you did. Come now, something happened in here, and I want to
+find out what it was."
+
+<P>
+"Oh, suffin done happened all right, Massa Tom. Yas, sah! Suffin
+done happened!" cried Eradicate, with such odd emphasis that Tom
+and Ned both laughed.
+
+<P>
+"An' suffin happened to me," went on the colored man, rubbing his
+shocked arm.
+
+<P>
+"Well, tell us about it," suggested Tom.
+
+<P>
+"It was dish yeah way," proceeded Eradicate. And he told more in
+detail how, seeing Koku cleaning and sweeping out the other
+telephone booth, he had thought of the trick to play on him. Both
+telephones had what are called "amplifiers" attached, that could
+be switched on when needed. These amplifiers were somewhat like
+the horn of a phonograph--they increased, or magnified the sound,
+so that one could hear a voice from any part of the shop, and need
+not necessarily have the telephone receiver at his ear.
+
+<P>
+Seeing Koku near the instrument, Eradicate had switched on the
+amplifier, and had called into his instrument, trying to scare the
+giant. And he did startle Koku, for the loud voice, coming so
+suddenly, sent the giant out of the booth on the run.
+
+<P>
+"But you must have done something else," insisted Tom. "Look here,
+Rad," and the young inventor pointed to the picture on the plate.
+
+<P>
+"Mah gracious sakes!" gasped the colored man. "Why dat's Koku
+hisse'f!" and he looked in awe at the likeness.
+
+<P>
+"That's what you did, Rad!"
+
+<P>
+"Me? I done dat? No, sah, Massa Tom. I neber did! No, sah!"
+Eradicate spoke emphatically.
+
+<P>
+"Yes you did, Rad. You took that picture of Koku over my photo
+telephone, and I want you to show me exactly what you did--what
+wires and switches you touched and changed, and all that."
+
+<P>
+"Yo--yo' done say I tuck dat pishure, Massa Tom?"
+
+<P>
+"You sure did, Rad."
+
+<P>
+"Well--well, good land o' massy! An' I done dat!"
+
+<P>
+Eradicate stared in wonder at the image of the giant on the plate,
+and shook his head doubtingly.
+
+<P>
+"I--I didn't know I could do it. I never knowed I had it in me!"
+he murmured.
+
+<P>
+Tom and Ned laughed long and loud, and then the young inventor
+said:
+
+<P>
+"Now look here, Rad. You've done me a mighty big service, though
+you didn't know it, and I want to thank you. I'm sorry about your
+arm, and I'll have the doctor look at it. But now I want you to
+show me all the things you touched when you played that joke on
+Koku. In some way you did what I haven't been able to do, You took
+the picture. There's probably just one little thing I've
+overlooked, and you stumbled on it by accident. Now go ahead and
+show me."
+
+<P>
+Eradicate thought for a moment, and then said:
+
+<P>
+"Well, I done turned on de current, laik I seen you done, Massa
+Tom."
+
+<P>
+"Yes, go on. You connected the telephone."
+
+<P>
+"Yas, sah. Den I switched on that flyer thing yo' all has rigged
+up."
+
+<P>
+"You switched on the amplifier, yes. Go on."
+
+<P>
+"An'--an' den I plugged in dish year wire," and the colored man
+pointed to one near the top of the booth.
+
+<P>
+"You switched on that wire, Rad! Why, great Scott, man! That's
+connected to the arc light circuit--it carries over a thousand
+volts. And you switched that into the telephone circuit?"
+
+<P>
+"Dat's what I done did, Massa Tom; yas, Bah!"
+
+<P>
+"What for?"
+
+<P>
+"Why, I done want t' make mah voice good an' loud t' skeer dat
+rascal Koku!"
+
+<P>
+Tom stared at the colored man in amazement.
+
+<P>
+"No wonder you got a shock!" exclaimed the young inventor. "You
+didn't get all the thousand volts, for part of it was shunted off;
+but you got a good charge, all right. So that's what did the
+business; eh? It was the combination of the two electrical
+circuits that sent the photograph over the wire."
+
+<P>
+"I understand it now, Rad; but you did more than I've been able to
+do. I never, in a hundred years, would have thought of switching
+on that current. It never occurred to me. But you, doing it by
+accident, brought out the truth. It's often that way in
+discoveries. And Koku was standing in the other telephone booth,
+near the plate there, when you switched in this current, Rad?"
+
+<P>
+"Yas, sah, Massa Tom. He were. An' yo' ought t' see him hop when
+he heard mah voice yellin' at him. Ha! ha! ha!"
+
+<P>
+Eradicate chuckled at the thought. Then a pain in his shocked arm
+made him wince. A wry look passed over his face.
+
+<P>
+"Yas, sah, Koku done jump about ten feet," he said. "An'--an' den
+I jump too. Ain't no use in denyin' dat fact. I done jump when I
+got dat shock!"
+
+<P>
+"All right, Rad. You may go now. I think I'm on the right track!"
+exclaimed Tom. "Come on, Ned, we'll try some experiments, and
+we'll see what we can do."
+
+<P>
+"No shocks though--cut out the shocks, Tom," stipulated his chum.
+
+<P>
+"Oh, sure! No shocks! Now let's bet busy and improve on
+Eradicate's Angel Gabriel system."
+
+<P>
+Tom made a quick examination of the apparatus.
+
+<P>
+"I understand it, I think," he said. "Koku was near the plate in
+the other booth when Rad put on the double current. There was a
+light there, and in an instant his likeness was sent over the
+wire, and imprinted on this plate. Now let's see what we can do.
+You go to that other booth, Ned. I'll see if I can get your
+picture, and send you mine. Here, take some extra selenium plates
+along. You know how to connect them."
+
+<P>
+"I think so," answered Ned.
+
+<P>
+"This image is really too faint to be of much use," went on Tom,
+as he looked at the one of Koku. "I think I can improve on it. But
+we're on the right track."
+
+<P>
+A little later Ned stood in the other booth, while Tom arranged
+the wires, and made the connections in the way accidently
+discovered by Eradicate. The young inventor had put in a new
+plate, carefully putting away the one with the picture of the
+giant, This plate could be used again, when the film, into which
+the image was imprinted, had been washed off.
+
+<P>
+"All ready, Ned," called Tom, over the wire, when he was about to
+turn the switch. "Stand still, and I'll get you."
+
+<P>
+The connection was made, and Tom uttered a cry of joy. For there,
+staring at him from the plate in front of him was the face of Ned.
+
+<P>
+It was somewhat reduced in size, of course, and was not extra
+clear, but anyone who knew Ned could have told he was at the other
+end of the wire.
+
+<P>
+"Do you get me, Tom?" called Ned, over the telephone.
+
+<P>
+"I sure do! Now see if you can get me."
+
+<P>
+Tom made other connections, and then looked at the sending plate
+of his instrument, there being both a sending and receiving plate
+in each booth, just as there was a receiver and a transmitter to
+the telephone.
+
+<P>
+"Hurray! I see you, Tom!" cried Ned, over the wire. "Say, this is
+great!"
+
+<P>
+"It isn't as good as I want it," went on Tom. "But it proves that
+I'm right. The photo telephone is a fact, and now persons using
+the wire can be sure of the other person they are conversing with.
+I must tell dad. He wouldn't believe I could do it!"
+
+<P>
+And indeed Mr. Swift was surprised when Tom proved, by actual
+demonstration, that a picture could be sent over the wire.
+
+<P>
+"Tom, I congratulate you!" declared the aged inventor. "It is good
+news!"
+
+<P>
+"Yes, but we have bad news of Mr. Damon," said Tom, and he told
+his father of the disappearance of the eccentric man. Mr. Swift at
+once telephoned his sympathy to Mrs. Damon, and offered to do
+anything he could for her.
+
+<P>
+"But Tom can help you more than I can," he said. "You can depend
+on Tom."
+
+<P>
+"I know that," replied Mrs. Damon, over the wire.
+
+<P>
+And certainly Tom Swift had many things to do now. He hardly knew
+at what to begin first, but now, since he was on the right road in
+regard to his photo telephone, he would work at improving it.
+
+<P>
+And to this end he devoted himself, after he had sent out a
+general alarm to the police of nearby towns, in regard to the
+disappearance of Mr. Damon. The airship clew, he believed, as did
+the police, would be a good one to work on.
+
+<P>
+For several days after this nothing of moment occurred. Mr. Damon
+could not be located, and Tom's airship might still be sailing
+above the clouds as far as getting any trace of it was concerned.
+
+<P>
+Meanwhile the young inventor, with the help of Ned, who was given
+a leave of absence from the bank, worked hard to improve the photo
+telephone.
+
+
+
+
+
+<P>
+<A NAME="XV"></A>
+<H3>Chapter XV The Airship Clew</H3>
+
+
+<P>
+"Now Ned, we'll try again. I'm going to use a still stronger
+current, and this is the most sensitive selenium plate I've turned
+out yet. We'll see if we can't get a better likeness of you--one
+that will be plainer."
+
+<P>
+It was Tom Swift who was speaking, and he and his chum had just
+completed some hard work on the new photo telephone. Though the
+apparatus did what Tom had claimed for it, still he was far from
+satisfied. He could transmit over the wire the picture of a person
+talking at the telephone, but the likeness was too faint to make
+the apparatus commercially profitable.
+
+<P>
+"It's like the first moving pictures," said Tom. "They moved, but
+that was about all they did."
+
+<P>
+"I say," remarked Ned, as he was about to take his place in the
+booth where the telephone and apparatus were located, "this
+double-strength electrical current you're speaking of won't shock
+me; will it? I don't want what happened to Eradicate to happen to
+me, Tom."
+
+<P>
+"Don't worry. Nothing will happen. The trouble with Rad was that
+he didn't have the wires insulated when he turned that arc current
+switch by mistake--or, rather, to play his joke. But he's all
+right now."
+
+<P>
+"Yes, but I'm not going to take any chances," insisted Ned. "I
+want to be insulated myself."
+
+<P>
+"I'll see to that," promised Tom. "Now get to your booth."
+
+<P>
+For the purpose of experiments Tom had strung a new line between
+two of his shops, They were both within sight, and the line was
+not very long; but, as I have said, Tom knew that if his apparatus
+would work over a short distance, it would also be successful over
+a long one, provided he could maintain the proper force of
+current, which he was sure could be accomplished.
+
+<P>
+"And if they can send pictures from Monte Carlo to Paris I can do
+the same," declared Tom, though his system of photo telephony was
+different from sending by a telegraph system--a reproduction of a
+picture on a copper plate. Tom's apparatus transmitted the
+likeness of the living person.
+
+<P>
+It took some little time for the young inventor, and Ned working
+with him, to fix up the new wires and switch on the current. But
+at last it was complete, and Ned took his place at one telephone,
+with the two sensitive plates before him. Tom did the same, and
+they proceeded to talk over the wire, first making sure that the
+vocal connection was perfect.
+
+<P>
+"All ready now, Ned! We'll try it," called Tom to his chum, over
+the wire. "Look straight at the plate. I want to get your image
+first, and then I'll send mine, if it's a success,"
+
+<P>
+Ned did as requested, and in a few minutes he could hear Tom
+exclaim, joyfully:
+
+<P>
+"It's better, Ned! It's coming out real clear. I can see you
+almost as plainly as if you were right in the booth with me. But
+turn on your light a little stronger."
+
+<P>
+Tom could hear, through the telephone, his chum moving about, and
+then he caught a startled exclamation.
+
+<P>
+"What's the matter?" asked Tom anxiously.
+
+<P>
+"I got a shock!" cried Ned. "I thought you said you had this thing
+fixed. Great Scott, Tom! It nearly yanked the arm off me! Is this
+a joke?"
+
+<P>
+"No, old man. No, of course not! Something must be wrong. I didn't
+mean that. Wait, I'll take a look. Say, it does seem as if
+everything was going wrong with this invention. But I'm on the
+right track, and soon I'll have it all right. Wait a second. I'll
+be right over."
+
+<P>
+Tom found that it was only a simple displacement of a wire that
+had given Ned a shock, and he soon had this remedied.
+
+<P>
+"Now we'll try again," he said. This time nothing wrong occurred,
+and soon Tom saw the clearest image he had yet observed on his
+telephone photo plate.
+
+<P>
+"Switch me on now, Ned," he called to his chum, and Ned reported
+that he could see Tom very plainly.
+
+<P>
+"So far--so good," observed Tom, as he came from the booth. "But
+there are several things I want yet to do."
+
+<P>
+"Such as what?" questioned Ned.
+
+<P>
+"Well, I want to arrange to have two kinds of pictures come over
+the wire. I want it so that a person can go into a booth, call up
+a friend, and then switch on the picture plate, so he can see his
+friend as well as talk to him. I want this plate to be like a
+mirror, so that any number of images can be made to appear on it.
+In that way it can be used over and over again. In fact it will be
+exactly like a mirror, or a telescope. No matter how far two
+persons may be apart they can both see and talk to one another."
+
+<P>
+"That's a big contract, Tom."
+
+<P>
+"Yes, but you've seen that it can be done. Then another thing I
+want to do is to have it arranged so that I can make a photograph
+of a person over a wire."
+
+<P>
+"Meaning what?"
+
+<P>
+"Meaning that if a certain person talks to me over the wire, I can
+turn my switch, and get a picture of him here at my apparatus
+connected with my telephone. To do that I'll merely need a sending
+apparatus at the other end of the telephone line--not a receiving
+machine."
+
+<P>
+"Could you arrange it so that the person who was talking to you
+would have his picture taken whether he wanted it or not?" asked
+Ned.
+
+<P>
+"Yes, it might be done," spoke Tom, thoughtfully. "I could conceal
+the sending plate somewhere in the telephone booth, and arrange
+the proper light, I suppose."
+
+<P>
+"That might be a good way in which to catch a criminal," went on
+Ned. "Often crooks call up on the telephone, but they know they
+are safe. The authorities can't see them--they can only hear them.
+Now if you could get a photograph of them while they were
+telephoning--"
+
+<P>
+"I see!" cried Tom, excitedly. "That's a great idea! I'll work on
+that, Ned."
+
+<P>
+And, all enthusiasm, Tom began to plan new schemes with his photo
+telephone.
+
+<P>
+The young inventor did not forget his promise to help Mrs. Damon.
+But he could get absolutely no clew to her husband's whereabouts.
+Mr. Damon had completely and mysteriously disappeared. His
+fortune, too, seemed to have been swallowed up by the sharpers,
+though lawyers engaged by Tom could fasten no criminal acts on Mr.
+Peters, who indignantly denied that he had done anything unlawful.
+
+<P>
+If he had, he had done it in such a way that he could not be
+brought to justice. The promoter was still about Shopton, as well
+groomed as ever, with his rose in his buttonhole, and wearing his
+silk hat. He still speeded up and down Lake Carlopa in his
+powerful motor boat. But he gave Tom Swift a wide berth.
+
+<P>
+Late one night, when Tom and Ned had been working at the new photo
+telephone, after all the rest of the household had retired, Tom
+suddenly looked up from his drawings and exclaimed:
+
+<P>
+"What's that?"
+
+<P>
+"What's what?" inquired Ned.
+
+<P>
+"That sound? Don't you hear it? Listen!"
+
+<P>
+"It's an airship--maybe yours coming back!" cried the young
+banker.
+
+<P>
+As he spoke Ned did hear, seemingly in the air above the house, a
+curious, throbbing, pulsating sound.
+
+<P>
+"That's so! It is an airship motor!" exclaimed Tom. "Come on out!"
+
+<P>
+Together they rushed from the house, but, ere they reached the
+yard, the sound had ceased. They looked up into the sky, but could
+see nothing, though the night was light from a full moon.
+
+<P>
+"I certainly heard it," said Tom.
+
+<P>
+"So did I," asserted Ned. "But where is it now?"
+
+<P>
+They advanced toward the group of work-buildings. Something
+showing white in the moonlight, before the hangar, caught Ned's
+eyes.
+
+<P>
+"Look!" he exclaimed. "There's an airship, Tom!"
+
+<P>
+The two rushed over to the level landing place before the big
+shed. And there, as if she had just been run out for a flight, was
+the <i>Eagle</i>. She had come back in the night, as mysteriously as she
+had been taken away.
+
+
+
+
+
+<P>
+<A NAME="XVI"></A>
+<H3>Chapter XVI Success</H3>
+
+
+<P>
+"Well, this gets me!" exclaimed Tom.
+
+<P>
+"It sure is strange," agreed Ned. "How did she come here?"
+
+<P>
+"She didn't come alone--that's sure," went on Tom. "Someone
+brought her here, made a landing, and got away before we could get
+out."
+
+<P>
+The two chums were standing near the <i>Eagle</i>, which had come back so
+mysteriously.
+
+<P>
+"Just a couple of seconds sooner and we'd have seen who brought
+her here," went on Tom. "But they must have shut off the motor
+some distance up, and then they volplaned down. That's why we
+didn't hear them."
+
+<P>
+Ned went over and put his hand on the motor.
+
+<P>
+"Ouch!" he cried, jumping back. "It's hot!"
+
+<P>
+"Showing that she's been running up to within a few minutes ago,"
+said Tom. "Well, as I said before, this sure does get me. First
+these mysterious men take my airship, and then they bring her back
+again, without so much as thanking me for the use of her."
+
+<P>
+"Who in the world can they be?" asked Ned.
+
+<P>
+"I haven't the least idea. But I'm going to find out, if it's at
+all possible. We'll look the machine over in the morning, and see
+if we can get any clews. No use in doing that now. Come on, we'll
+put her back in the hangar."
+
+<P>
+"Say!" exclaimed Ned, as a sudden idea came to him. "It couldn't
+be Mr. Damon who had your airship; could it, Tom?"
+
+<P>
+"I don't know. Why do you ask that?"
+
+<P>
+"Well, he might have wanted to get away from his enemies for a
+while, and he might have taken your <i>Eagle</i>, and--"
+
+<P>
+"Mr. Damon wouldn't trail along with a crowd like the one that
+took away my airship," said Tom, decidedly. "You've got another
+guess coming, Ned. Mr. Damon had nothing to do with this."
+
+<P>
+"And yet the night he disappeared an airship was heard near his
+house."
+
+<P>
+"That's so. Well, I give up. This is sure a mystery. We'll have a
+look at it in the morning. One thing I'll do, though, I'll
+telephone over to Mr. Damon's house and see if his wife has heard
+any news. I've been doing that quite often of late, so she won't
+think anything of it. In that way we can find out if he had
+anything to do with my airship. But let's run her into the shed
+first."
+
+<P>
+This was done, and Koku, the giant, was sent to sleep in the
+hangar to guard against another theft. But it was not likely that
+the mysterious men, once having brought the airship back, would
+come for it again.
+
+<P>
+Tom called up Mrs. Damon on the telephone, but there was no news
+of the missing man. He expressed his sympathy, and said he would
+come and see her soon. He told Mrs. Damon not to get discouraged,
+adding that he, and others, were doing all that was possible. But,
+in spite of this, Mrs. Damon, naturally, did worry.
+
+<P>
+The next morning the two chums inspected the airship, so
+mysteriously returned to them. Part after part they went over, and
+found nothing wrong. The motor ran perfectly, and there was not so
+much as a bent spoke in the landing wheels. For all that could be
+told by an inspection of the craft she might never have been out
+of the hangar.
+
+<P>
+"Hello, here's something!" cried Tom, as he got up from the
+operator's seat, where he had taken his place to test the various
+controls.
+
+<P>
+"What is it?" asked Ned.
+
+<P>
+"A button. A queer sort of a button. I never had any like that on
+my clothes, and I'm sure you didn't. Look!" and Tom held out a
+large, metal button of curious design.
+
+<P>
+"It must have come off the coat of one of the men who had your
+airship, Tom," said his chum. "Save it. You may find that it's a
+clew."
+
+<P>
+"I will. No telling what it may lead to. Well, I guess that's all
+we can find."
+
+<P>
+And it was. But Tom little realized what a clew the button was
+going to be. Nothing more could be learned by staring at the
+returned airship, so he and Ned went back to the house.
+
+<P>
+Tom Swift had many things to do, but his chief concern was for the
+photo telephone. Now that he was near the goal of success he
+worked harder than ever. The idea Ned had given him of being able
+to take the picture of a person at the instrument--without the
+knowledge of that person--appealed strongly to Tom.
+
+<P>
+"That's going to be a valuable invention!" he declared, but little
+he knew how valuable it would prove to him and to others.
+
+<P>
+It was about a week later when Tom was ready to try the new
+apparatus. Meanwhile he had prepared different plates, and had
+changed his wiring system. In the days that had passed nothing new
+had been learned concerning the whereabouts of Mr. Damon, nor of
+the men who had so mysteriously taken away Tom's airship.
+
+<P>
+All was in readiness for the trial. Tom sent Ned to the booth that
+he had constructed in the airship hangar, some distance away from
+the house. The other booth Tom had placed in his library, an
+entirely new system of wires being used.
+
+<P>
+"Now Ned," explained Tom, "the idea is this! You go into that
+booth, just as if it were a public one, and ring me up in the
+regular way. Of course we haven't a central here, but that doesn't
+matter. Now while I'm talking to you I want to see you. You don't
+know that, of course."
+
+<P>
+"The point is to see if I can get your picture while you're
+talking to me, and not let you know a thing about it."
+
+<P>
+"Think you can do it, Tom?"
+
+<P>
+"I'm going to try. We'll soon know. Go ahead."
+
+<P>
+A little later Ned was calling up his chum, as casually as he
+could, under the circumstances.
+
+<P>
+"All right!" called Tom to his chum. "Start in and talk. Say
+anything you like--it doesn't matter. I want to see if I can get
+your picture. Is the light burning in your booth?"
+
+<P>
+"Yes, Tom."
+
+<P>
+"All right then. Go ahead."
+
+<P>
+Ned talked of the weather--of anything. Meanwhile Tom was busy.
+Concealed in the booth occupied by Ned was a sending plate. It
+could not be seen unless one knew just where to look for it. In
+Tom's booth was a receiving plate.
+
+<P>
+The experiment did not take long. Presently Tom called to Ned that
+he need stay there no longer.
+
+<P>
+"Come on to the house," invited the young inventor, "and we'll
+develope this plate." For in this system it was necessary to
+develope the receiving plate, as is done with an ordinary
+photographic one. Tom wanted a permanent record.
+
+<P>
+Eagerly the chums in the dark room looked down into the tray
+containing the plate and the developing solution.
+
+<P>
+"Something's coming out!" cried Ned, eagerly.
+
+<P>
+"Yes! And it's you!" exclaimed Tom. "See, Ned, I got your picture
+over the telephone. Success! I've struck it! This is the best
+yet!"
+
+<P>
+At that moment, as the picture came out more and more plainly,
+someone knocked on the door of the dark room.
+
+<P>
+"Who is it?" asked Tom.
+
+<P>
+"Gen'man t' see you," said Eradicate. "He say he come from Mistah
+Peters!"
+
+<P>
+"Mr. Peters--that rascally promoter!" whispered Tom to his chum.
+"What does this mean?"
+
+
+
+
+
+<P>
+<A NAME="XVII"></A>
+<H3>Chapter XVII The Mysterious Message</H3>
+
+
+<P>
+Tom Swift and his chum looked at one another strangely for a
+moment in the dim, red light of the dark room. Then the young
+inventor spoke:
+
+<P>
+"I'm not going to see him. Tell him so, Rad!"
+
+<P>
+"Hold on a second," suggested Ned. "Maybe you had better see him,
+Tom. It may have something to with Mr. Damon's lost fortune."
+
+<P>
+"That's so! I didn't think of that. And I may get a clew to his
+disappearance, though I don't imagine Peters had anything to do
+with that. Wait, Rad. Tell the gentleman I'll see him. Did he give
+any name, Rad?"
+
+<P>
+"Yas, sah. Him done say him Mistah Boylan."
+
+<P>
+"The same man who called to see me once before, trying to get me
+to do some business with Peters," murmured Tom. "Very well, I'll
+see him as soon as this picture is fixed. Tell him to wait, Rad."
+
+<P>
+A little later Tom went to where his caller awaited in the
+library. This time there were no plans to be looked at, the young
+inventor having made a practice of keeping all his valuable papers
+locked in a safe.
+
+<P>
+"You go into the next room, Ned," Tom had said to his chum. "Leave
+the door open, so you can hear what is said."
+
+<P>
+"Why, do you think there'll be trouble? Maybe we'd better have
+Koku on hand to--"
+
+<P>
+"Oh, no, nothing like that," laughed Tom. "I just want you to
+listen to what's said so, if need be, you can be a witness later.
+I don't know what their game is, but I don't trust Peters and his
+crowd. They may want to get control of some of my patents, and
+they may try some underhanded work. If they do I want to be in a
+position to stop them."
+
+<P>
+"All right," agreed Ned, and he took his place.
+
+<P>
+But Mr. Boylan's errand was not at all sensational, it would seem.
+He bowed to Tom, perhaps a little distantly, for they had not
+parted the best of friends on a former occasion.
+
+<P>
+"I suppose you are surprised to see me," began Mr. Boylan.
+
+<P>
+"Well, I am, to tell the truth," Tom said, calmly.
+
+<P>
+"I am here at the request of my employer, Mr. Peters," went on the
+caller. "He says he is forming a new and very powerful company to
+exploit airships, and he wants to know whether you would not
+reconsider your determination not to let him do some business for
+you."
+
+<P>
+"No, I'm afraid I don't care to go into anything like that," said
+Tom.
+
+<P>
+"It would be a good thing for you," proceeded Mr. Boylan, eagerly.
+"Mr. Peters is able to command large capital, and if you would
+permit the use of your airships--or one of them--as a model, and
+would supervise the construction of others, we could confidently
+expect large sales. Thus you would profit, and I am frank to admit
+that the company, and Mr. Peters, also, would make money. Mr.
+Peters is perfectly free to confess that he is in business to make
+money, but he is also willing to let others share with him. Come
+now, what do you say?"
+
+<P>
+"I am sorry, but I shall have to say the same thing I said
+before," replied Tom. "Nothing doing!"
+
+<P>
+Mr. Boylan glanced rather angrily at the young inventor, and then,
+with a shrug of his shoulders, remarked:
+
+<P>
+"Well, you have the say, of course. But I would like to remind you
+that this is going to be a very large airship company, and if your
+inventions are not exploited some others will be. And Mr. Peters
+also desired me to say that this is the last offer he would make
+you."
+
+<P>
+"Tell him," said Tom, "that I am much obliged, but that I have no
+business that I can entrust to him. If he wishes to make some
+other type of airship, that is his affair. Good-day."
+
+<P>
+As Mr. Boylan was going out Tom noticed a button dangling from the
+back of his caller's coat. It hung by a thread, being one of the
+pair usually sewed on the back of a cutaway garment.
+
+<P>
+"I think you had better take off that button before it falls,"
+suggested Tom. "You may lose it, and perhaps it would be hard to
+match."
+
+<P>
+"That's so. Thank you!" said Mr. Boylan. He tried to reach around
+and get it, but he was too stout to turn easily, especially as the
+coat was tight-fitting.
+
+<P>
+"I'll get it for you," offered Tom, as he pulled it off. "There is
+one missing, though," he said, as he handed the button to the man.
+And then Tom started as he saw the pattern of the one in his hand.
+
+<P>
+"One gone? That's too bad," murmured Mr. Boylan. "Those buttons
+were imported, and I doubt if I can replace them. They are rather
+odd."
+
+<P>
+"Yes," agreed Tom, gazing as if fascinated at the one he still
+held. "They are rather odd."
+
+<P>
+And then, as he passed it over, like a flash it came to him where
+he had seen a button like that before. He had found it in his
+airship, which had been so mysteriously taken away and returned.
+
+<P>
+Tom could hardly restrain his impatience until Mr. Boylan had
+gone. The young inventor had half a notion to produce the other
+button, matching the one he had just pulled off his visitor's
+coat, and tell where he had found it. But he held himself back. He
+wanted to talk first to Ned.
+
+<P>
+And, when his chum came in, Tom cried:
+
+<P>
+"Ned, what do you think? I know who had my airship!"
+
+<P>
+"How?" asked Ned, in wonder.
+
+<P>
+"By that button clew! Yes, it's the same kind--they're as alike as
+twins!" and Tom brought out the button which he had put away in
+his desk. "See, Boylan had one just like this on the back of his
+coat. The other was missing. Here it is--it was in the seat of my
+airship, where it was probably pulled off as he moved about. Ned,
+I think I've got the right clew at last."
+
+<P>
+Ned said nothing for several seconds. Then he remarked slowly:
+
+<P>
+"Well, Tom, it proves one thing; but not the other."
+
+<P>
+"What do you mean?"
+
+<P>
+"I mean that it may be perfectly true that the button came off Mr.
+Boylan's coat, but that doesn't prove that he wore it. You can be
+reasonably sure that the coat was having a ride in your <i>Eagle</i>, but
+was Boylan in the coat? That's the question."
+
+<P>
+"In the coat? Of course he was in it!" cried Tom.
+
+<P>
+"You can't be sure. Someone may have borrowed his coat to take a
+midnight ride in the airship."
+
+<P>
+"Mr. Boylan doesn't look to be the kind of a man who would lend
+his clothes," remarked Tom.
+
+<P>
+"You never can tell. Someone may have borrowed it without his
+knowledge. You'd better go a bit slow, Tom."
+
+<P>
+"Well, maybe I had. But it's a clew, anyhow."
+
+<P>
+Ned agreed to this.
+
+<P>
+"And all I've got to do is to find out who was in the coat when it
+was riding about in my airship," went on Tom.
+
+<P>
+"Yes," said Ned, "and then maybe you'll have some clew to the
+disappearance of Mr. Damon."
+
+<P>
+"Right you are! Come on, let's get busy!"
+
+<P>
+"As if we hadn't been busy all the while!" laughed Ned. "I'll lose
+my place at the bank if I don't get back soon."
+
+<P>
+"Oh, stay a little longer--a few days," urged Tom. "I'm sure that
+something is going to happen soon. Anyhow my photo telephone is
+about perfected. But I've just thought of another improvement."
+
+<P>
+"What is it?"
+
+<P>
+"I'm going to arrange a sort of dictaphone, or phonograph, so I
+can get a permanent record of what a person says over the wire, as
+well as get a picture of him saying it. Then everything will be
+complete. This last won't be hard to do, as there are several
+machines on the market now, for preserving a record of telephone
+conversations. I'll make mine a bit different, though."
+
+<P>
+"Tom, is there any limit to what you're going to do?" asked Ned,
+admiringly.
+
+<P>
+"Oh, yes, I'm going to stop soon, and retire," laughed the young
+inventor.
+
+<P>
+After talking the matter over, Tom and his chum decided to wait a
+day or so before taking any action in regard to the button clew to
+the takers of the airship. After all, no great harm had been done,
+and Tom was more anxious to locate Mr. Damon, and try to get back
+his fortune, as well as to perfect his photo telephone, than he
+was to discover those who had helped themselves to the <i>Eagle</i>.
+
+<P>
+Tom and Ned put in some busy days, arranging the phonograph
+attachment. It was easy, compared to the hard work of sending a
+picture over the wire. They paid several visits to Mrs. Damon, but
+she had no news of her missing husband, and, as the days went by,
+she suffered more and more under the strain.
+
+<P>
+Finally Tom's new invention was fully completed. It was a great
+success, and he not only secured pictures of Ned and others over
+the wire, as he talked to them, but he imprinted on wax cylinders,
+to be reproduced later, the very things they said.
+
+<P>
+It was a day or so after he had demonstrated his new attachment
+for the first time, that Tom received a most urgent message from
+Mrs. Damon.
+
+<P>
+"Tom," she said, over the telephone, "I wish you would call.
+Something very mysterious has happened."
+
+<P>
+"Mr. Damon hasn't come back; has he?" asked Tom eagerly.
+
+<P>
+"No--but I wish I could say he had. This concerns him, however.
+Can you come?"
+
+<P>
+"I'll be there right away."
+
+<P>
+In his speedy monoplane Tom soon reached Waterford. Ned did not
+accompany him this time.
+
+<P>
+"Now what is it, Mrs. Damon?" asked the young inventor.
+
+<P>
+"About half an hour before I called you," she said, "I received a
+mysterious message."
+
+<P>
+"Who brought it?" asked Tom quickly.
+
+<P>
+"No one. It came over the telephone. Someone, whose voice I did
+not know, said to me: 'Sign the land papers, and send them to us,
+and your husband will be released.'"
+
+<P>
+"That message came over the wire?" cried Tom, excitedly.
+
+<P>
+"Yes," answered Mrs. Damon. "Oh, I am so frightened! I don't know
+what to do!" and the lady burst into tears.
+
+
+
+
+
+<P>
+<A NAME="XVIII"></A>
+<H3>Chapter XVIII Another Call</H3>
+
+
+<P>
+Tom Swift, for the moment, did not know what to do. It was a
+strange situation, and one he had never thought of. What did the
+mysterious message mean? He must think it all out, and plan some
+line of action. Clearly Mrs. Damon was not able to do so.
+
+<P>
+"Now let's get at this in some kind of order," suggested the
+youth, when Mrs. Damon had calmed herself. It was his habit to
+have a method about doing things. "And don't worry," he advised.
+"I am certain some good will come of this. It proves one thing,
+that's sure."
+
+<P>
+"What is it, Tom?"
+
+<P>
+"That Mr. Damon is alive and well. Otherwise the message would not
+have said he would be 'released.' It wasn't from anyone you know;
+was it?"
+
+<P>
+"No, I'm sure I never heard the voice before."
+
+<P>
+Tom paused a moment to think how useful his photo telephone and
+phonograph arrangement might have been in this case.
+
+<P>
+"How did the telephone call come in?" inquired the young inventor.
+
+<P>
+"In the usual way," answered Mrs. Damon. "The bell rang, and, as I
+happened to be near the instrument, I answered it, as I often do,
+when the maid is busy. A voice asked if I was Mrs. Damon, and of
+course I said I was. Then I heard this: 'Sign the land papers, and
+send them to us, and your husband will be released.'"
+
+<P>
+"Was that all?" Tom asked.
+
+<P>
+"I think so--I made a note of it at the time." Mrs. Damon looked
+into a small red book. "No, that wasn't all," she said, quickly.
+"I was so astonished, at hearing those strange words about my
+husband, that I didn't know what to say. Before I could ask any
+questions the voice went on to say, rather abruptly: 'We will call
+you again.'"
+
+<P>
+"That's good!" cried Tom. "I only hope they do it while I am here.
+Perhaps I can get some clew as to who it was called you. But was
+this all you heard?"
+
+<P>
+"Yes, I'm sure that was all. I had forgotten about the last words,
+but I see I have them written down in my note book."
+
+<P>
+"Did you ask any questions?" inquired Tom.
+
+<P>
+"Oh, indeed I did! As soon as I got over being stunned by what I
+heard, I asked all sorts of questions. I demanded to know who was
+speaking, what they meant, where they were, and all that. I begged
+them to tell me something of my husband."
+
+<P>
+"And what did they say?"
+
+<P>
+"Not a thing. There wasn't a sound in the telephone. The receiver was
+hung up, breaking the connection after that message to me--that
+mysterious message."
+
+<P>
+"Yes, it was mysterious," agreed Tom, thoughtfully. "I can't
+understand it. But didn't you try to learn from the central
+operator where the call had come from?"
+
+<P>
+"Oh, yes, indeed, Tom! As soon as I found out the person speaking
+to me had rung off, I got the girl in the exchange."
+
+<P>
+"And what did she say?"
+
+<P>
+"That the call came from an automatic pay station in a drug store
+in town. I have the address. It was one of those telephones where
+you put your money for the call in a slot."
+
+<P>
+"I see. Well, the first thing to do is for me to go to that drug
+store and find out, if I can, who used the telephone about that
+time. It's a slim chance, but we'll have to take it. Was it a
+man's voice, or a woman's?"
+
+<P>
+"Oh, a man's, I'm sure. It was very deep and heavy. No woman could
+speak like that."
+
+<P>
+"So much is settled, anyhow. Now about the land papers--what was
+meant?"
+
+<P>
+"I'll tell you," said Mrs. Damon. "You know part of our
+property--considerable land and some buildings--is in my
+name. Mr. Damon had it fixed so a number of years ago, in order to
+protect me. No one could get this property, and land, unless I signed
+the deeds, or agreed to sign them. Now all of Mr. Damon's fortune is
+tied up in some of Mr. Peters's companies. That is why my husband has
+disappeared."
+
+<P>
+"He didn't disappear--he was taken away against his will; I'm
+positive of that!" exclaimed Tom.
+
+<P>
+"Perhaps so," agreed Mrs. Damon, sadly. "But those are the papers
+referred to, I'm sure."
+
+<P>
+"Probably," assented Tom. "The rascals want to get control of
+everything--even your possessions. Not satisfied with ruining Mr.
+Damon, they want to make you a beggar, too. So they are playing on
+your fears. They promise to release your husband if you will give
+them the land."
+
+<P>
+"Yes, that must be it, Tom. What would you advise me to do? I am
+so frightened over this!"
+
+<P>
+"Do? Don't you do anything!" cried Tom. "We'll fool these rascals
+yet. If they got those papers they might release Mr. Damon, or
+they might not--fearing he would cause their arrest later. But
+we'll have him released anyhow, and we'll save what is left of
+your fortune. Put those land papers in a safe-deposit box, and let
+me do the rest. I'm going to catch those fellows!"
+
+<P>
+"But how, Tom? You don't know who they are. And a mere message
+over a telephone won't give you a clew to where they are."
+
+<P>
+"Perhaps not an ordinary message," agreed Tom. "But I'm going to
+try some of my new inventions. You said they told you they were
+going to call again?"
+
+<P>
+"That's what they said, Tom."
+
+<P>
+"Well, when they do, I want to be here. I want to listen to that
+message. If you will allow me, I'll take up my residence here for
+a while, Mrs. Damon."
+
+<P>
+"Allow you? I'll be only too glad if you will, Tom. But I thought
+you were going to try to get some clew from the drug store where
+the mysterious message came from."
+
+<P>
+"I'll let Ned Newton do that. I want to stay here."
+
+<P>
+Tom telephoned to Ned to meet him at Mrs. Damon's house, and also
+to bring with him certain things from the laboratory. And when Ned
+arrived in an auto, with various bits of apparatus, Tom put in
+some busy hours.
+
+<P>
+Meanwhile Ned was sent to the drug store, to see if any clews
+could be obtained there as to who had sent the message. As Tom had
+feared, nothing could be learned. There were several automatic
+'phones in the place, and they were used very often during the day
+by the public. The drug clerks took little or no notice of the
+persons entering or leaving the booths, since the dropping of a
+coin in the slot was all that was necessary to be connected with
+central.
+
+<P>
+"Well, we've got to wait for the second call here," said Tom, who
+had been busy during Ned's absence. He had fitted to Mrs. Damon's
+telephone a recording wax phonograph cylinder, to get a record of
+the speaker's voice. And he had also put in an extension
+telephone, so that he could listen while Mrs. Damon talked to the
+unknown.
+
+<P>
+"There, I guess we're ready for them," said Tom, late that
+afternoon. But no queer call came in that day. It was the next
+morning. about ten o'clock, after Mrs. Damon had passed a restless
+night, that the telephone bell rang. Tom, who was on the alert,
+was at his auxiliary instrument in a flash. He motioned to Mrs.
+Damon to answer on the main wire.
+
+<P>
+"Hello," she spoke into the transmitter. "Who is this?"
+
+<P>
+"Are you Mrs. Damon?" Tom heard come over the wire in a deep
+voice, and by the manner in which Mrs. Damon signalled the young
+inventor knew that, at the other end of the line, was the
+mysterious man who had spoken before.
+
+
+
+
+
+<P>
+<A NAME="XIX"></A>
+<H3>Chapter XIX The Buzzing Sound</H3>
+
+
+<P>
+"Are you Mrs. Damon?" came the question again--rather more
+impatiently this time, Tom thought.
+
+<P>
+"Yes," answered the lady, glancing over at Tom. The extension
+telephone was in the same room. Softly Tom switched on the
+phonograph attachment. The little wax cylinder began to revolve
+noiselessly, ready to record the faintest word that came over the
+wire.
+
+<P>
+"You got a message from me yesterday," went on the hoarse voice.
+In vain Tom tried to recall whether or not he had heard it before.
+He could not place it.
+
+<P>
+"Who are you?" asked Mrs. Damon. She and Tom had previously agreed
+on a line of talk. "Tell me your name, please."
+
+<P>
+"There's no need for any names to be used," went on the unknown at
+the other end of the wire. "You heard what I said yesterday. Are
+you willing to send me those land title papers, if we release your
+husband?"
+
+<P>
+"But where shall I send them?" asked Mrs. Damon, to gain time.
+
+<P>
+"You'll be told where. And listen--no tricks! You needn't try to
+find out who I am, nor where I am. Just send those papers if you
+want to see your husband again."
+
+<P>
+"Oh, how is he? Tell me about him! You are cruel to keep him a
+prisoner like this! I demand that you release him!"
+
+<P>
+Tom had not told Mrs. Damon to say this. It came out of her own
+heart--she could not prevent the agonized outburst.
+
+<P>
+"Never mind about that, now," came the gruff voice over the wire.
+"Are you willing to send the papers?"
+
+<P>
+Mrs. Damon looked over to Tom for silent instructions. He nodded
+his head in assent.
+
+<P>
+"Yes, I--I will send them if you tell me where to get them to you--if
+you will release Mr. Damon," said the anxious wife. "But tell me who
+you are--and where you are!" she begged.
+
+<P>
+"None of that! I'm not looking to be arrested. You get the papers
+ready, and I'll let you know to-morrow, about this time, where to
+send them."
+
+<P>
+"Wait a minute!" called Mrs. Damon, to gain more time. "I must
+know just what papers you want."
+
+<P>
+"All right, I'll tell you," and he began to describe the different
+ones.
+
+<P>
+It took a little time for the unknown to give this information to
+Mrs. Damon. The man was very particular about the papers. There
+were trust deeds, among other things, and he probably thought that
+once he had possession of them, with Mrs. Damon's signature, even
+though it had been obtained under a threat, he could claim the
+property. Later it was learned that such was not the case, for
+Mrs. Damon, with Tom's aid, could have proved the fraud, had the
+scoundrels tried to get the remainder of the Damon fortune.
+
+<P>
+But at the time it seemed to the helpless woman that everything
+she owned would be taken from her. Though she said she did not
+care, as long as Mr. Damon was restored to her.
+
+<P>
+As I have said, the telephoning of the instructions about the
+papers took some time. Tom had counted on this, and had made his
+plans accordingly.
+
+<P>
+As soon as the telephone call had come in, Tom had communicated
+with a private detective who was in waiting, and this man had gone
+to the drug store whence the first call had come. He was going to
+try to make the arrest of the man telephoning.
+
+<P>
+But for fear the scoundrel would go to a different instrument, Tom
+took another precaution. This was to have one of the operators in
+the central exchange on the watch. As soon as Mrs. Damon's house
+was in connection with another telephone, the location of the
+latter would be noted, and another private detective would be sent
+there. Thus Tom hoped to catch the man at the 'phone.
+
+<P>
+Meanwhile Tom listened to the hoarse voice at the other end of the
+wire, giving the directions to Mrs. Damon. Tom hoped that soon
+there would be an arrest made.
+
+<P>
+Meanwhile the talk was being faithfully recorded on the phonograph
+cylinder. And, as the man talked on, Tom became aware of a curious
+undercurrent of sound. It was a buzzing noise, that Tom knew did
+not come from the instrument itself. It was not the peculiar
+tapping, singing noise heard in a telephone receiver, caused by
+induced electrical currents, or by wire trouble.
+
+<P>
+"This is certainly different," mused Tom. He was trying to recall
+where he had heard the noise before. Sometimes it was faint, and
+then it would gradually increase, droning off into faintness once
+more. Occasionally it was so loud that Mrs. Damon could not hear
+the talk about the papers, and the man would have to repeat.
+
+<P>
+But finally he came to an end.
+
+<P>
+"This is all now," he said, sharply. Tom heard the words above the
+queer, buzzing, humming sound. "You are keeping me too long. I
+think you are up to some game, but it won't do you any good, Mrs.
+Damon. I'll 'phone you to-morrow where to send the papers. And if
+you don't send them--if you try any tricks--it will be the worse
+for you and Mr. Damon!"
+
+<P>
+There was a click, that told of a receiver being placed back on
+the hook, and the voice ceased. So, also, did the queer, buzzing
+sound over which Tom puzzled.
+
+<P>
+"What can it have been?" he asked. "Did you hear it, Mrs. Damon?"
+
+<P>
+"What, Tom?"
+
+<P>
+"That buzzing sound."
+
+<P>
+"Yes, I heard, but I didn't know what it was. Oh, Tom, what shall
+I do?"
+
+<P>
+"Don't worry. We'll see if anything happened. They may have caught
+that fellow. If not I'll plan another scheme."
+
+<P>
+Tom's first act was to call up the telephone exchange to learn
+where the second call had come from. He got the information at
+once. The address was in the suburbs. The man had not gone to the
+drug store this time.
+
+<P>
+"Did the detective get out to that address?" asked Tom eagerly of
+the manager.
+
+<P>
+"Yes. As soon as we were certain that he was the party you wanted,
+your man got right after him, Mr. Swift."
+
+<P>
+"That's good, I hope he catches him!" cried the young inventor. "We'll
+have to wait and find out."
+
+<P>
+"He said he'd call up and let you know as soon as he reached the
+place," the telephone manager informed Tom.
+
+<P>
+There was nothing to do but wait, and meanwhile Tom did what he
+could to comfort Mrs. Damon. She was quite nervous and inclined to
+be hysterical, and the youth thought it wise to have a cousin, who
+had come to stay with her, summon the doctor.
+
+<P>
+"But, Tom, what shall I do about those papers?" Mrs. Damon asked
+him. "Shall I send them?"
+
+<P>
+"Indeed not!"
+
+<P>
+"But I want Mr. Damon restored to me," she pleaded. "I don't care
+about the money. He can make more."
+
+<P>
+"Well, we'll not give those scoundrels the satisfaction of getting
+any money out of you. Just wait now, I'll work this thing out, and
+find a way to catch that fellow. If I could only think what that
+buzzing sound was--"
+
+<P>
+Then, in a flash, it came to Tom.
+
+<P>
+"A sawmill! A planing mill!" he cried. "That's what it was! That
+fellow was telephoning from some place near a sawmill!"
+
+<P>
+The telephone rang in the midst of Tom's excited comments.
+
+<P>
+"Yes--yes!" he called eagerly. "Who is it--what is it?"
+
+<P>
+"This is Larsen--the private detective you sent."
+
+<P>
+"Oh, yes, you were at the drug store."
+
+<P>
+"Yes, Mr. Swift. Well, that party didn't call up from here."
+
+<P>
+"I know, Larsen. It was from another station. We're after him.
+Much obliged to you. Come on back."
+
+<P>
+Tom was sure his theory was right. The man had called up the Damon
+house from some telephone near a sawmill. And a little later Tom's
+theory was proved to be true. He got a report from the second
+detective. Unfortunately the man had not been able to reach the
+telephone station before the unknown speaker had departed.
+
+<P>
+"Was the place near a sawmill?" asked Tom, eagerly.
+
+<P>
+"It was," answered the detective over the wire. "The telephone is
+right next door to one. It's an automatic pay station and no one
+seems to have noticed who the man was who telephoned. I couldn't
+get a single clew. I'm sorry."
+
+<P>
+"Never mind," said Tom, as cheerfully as he could. "I think I'm on
+the right track now. I'm going to lay a trap for this fellow."
+
+
+
+
+
+<P>

+
+
+<P>
+Troublesome problems seemed to be multiplying for Tom Swift. He
+admitted as much himself after the failure to capture the man who
+had telephoned to Mrs. Damon. He had hoped that his plan of
+sending detectives to the location of the telephones would
+succeed. Since it had not the youth must try other means.
+
+<P>
+"Now, Ned," he said to his chum, when they were on their way from
+Mrs. Damon's, it being impossible to do anything further there.
+"Now, Ned, we've got to think this thing out together."
+
+<P>
+"I'm willing, Tom. I'll do what I can."
+
+<P>
+"I know you will. Now the thing to do is to go at this thing
+systematically. Otherwise we'll be working around in a circle, and
+won't get anywhere. In the first place, let's set down what we do
+know. Then we'll put down what we don't know, and go after that."
+
+<P>
+"Put down what you don't know?" exclaimed Ned. "How are you going
+to put down a thing when you don't know it?"
+
+<P>
+"I mean we can put a question mark after it, so to speak. For
+instance we don't know where Mr. Damon is, but we want to find
+out."
+
+<P>
+"Oh, I see. Well, let's start off with the things we do know."
+
+<P>
+The two friends were at Tom's house by now, having come from
+Waterford in Tom's airship. After thinking over all the exciting
+happenings of the past few days, Tom remarked: "Now, Ned, for the
+things we do know. In the first place Mr. Damon is missing, and
+his fortune is about gone. There is considerable left to Mrs.
+Damon, however, but those scoundrels may get that away from her,
+if we don't watch out. Secondly, my airship was taken and brought
+back, with a button more than it had when it went away. Said
+button exactly matched one off Mr. Boylan's coat."
+
+<P>
+"Thirdly, Mr. Damon was either taken away or went away, in an
+airship--either in mine or someone else's. Fourthly, Mrs. Damon
+has received telephonic communications from the man, or men, who
+have her husband. Fifthly, Mr. Peters, either legally or
+illegally, is responsible for the loss of Mr. Damon's fortune.
+Now: there you are--for the things we do know."
+
+<P>
+"Now for the things we don't know. We don't know who has taken
+Mr. Damon away, nor where he is, to begin with the most important."
+
+<P>
+"Hold on, Tom, I think you're wrong," broke in Ned.
+
+<P>
+"In what way?"
+
+<P>
+"About not knowing who is responsible for the taking away of Mr.
+Damon. I think it's as plain as the nose on your face that Peters
+is responsible."
+
+<P>
+"I can't see it that way," said Tom, quickly. "I will admit that
+it looks as though Boylan had been in my airship, but as for
+Peters taking Mr. Damon away--why, Peters is around town all the
+while, and if he had a hand in the disappearance of Mr. Damon, do
+you think he'd stay here, when he knows we are working on the
+case? And would he send Boylan to see me if Boylan had been one of
+those who had a hand in it? They wouldn't dare, especially as they
+know I'm working on the case."
+
+<P>
+"Peters is a bad lot. I'll grant you, though, he was fair enough
+to pay for my motor boat. I don't believe he had anything to do
+with taking Mr. Damon away."
+
+<P>
+"Do you think he was the person who was talking to Mrs. Damon
+about the papers?"
+
+<P>
+"No, Ned. I don't. I listened to that fellow's voice carefully. It
+wasn't like Peters's. I'm going to put it in the phonograph, too,
+and let you listen to it. Then see what you say."
+
+<P>
+Tom did this, a little later. The record of the voice, as it came
+over the wire, was listened to from the wax cylinder, and Ned had
+to admit that it was not much like that of the promoter.
+
+<P>
+"Well, what's next to be done?" asked the young banker.
+
+<P>
+"I'm going to set a trap," replied Tom, with a grin.
+
+<P>
+"Set a trap?"
+
+<P>
+"Yes, a sort of mouse-trap. I'm glad my photo telephone is now
+perfected, Ned."
+
+<P>
+"What has that got to do with it?"
+
+<P>
+"That's going to be my trap, Ned. Here is my game. You know this
+fellow--this strange unknown--is going to call up Mrs. Damon to-morrow.
+Well, I'll be ready for him. I'm going to put in the booth
+where he will telephone from, one of my photo telephones--that is,
+the sending apparatus. In Mrs. Damon's house, attached to her
+telephone, will be the receiving plate, as well as the phonograph
+cylinder."
+
+<P>
+"When this fellow starts to talk he'll be sending us his picture,
+though he won't know it, and we'll be getting a record of his
+voice. Then we'll have him just where we want him."
+
+<P>
+"Good!" cried Ned. "But, Tom, there's a weak spot in your mouse-trap."
+
+
+<P>
+"What is it?"
+
+<P>
+"How are you going to know which telephone the unknown will call
+up from? He may go to any of a hundred, more or less."
+
+<P>
+"He might--yes. But that's a chance we've got to take. It isn't so
+much of a chance, though when you stop to think that he will
+probably go to some public telephone in an isolated spot, and,
+unless I'm much mistaken he will go to a telephone near where he
+was to-day. He knows that was safe, since we didn't capture him,
+and he's very likely to come back."
+
+<P>
+"But to make the thing as sure as possible, I'm going to attach my
+apparatus to a number of public telephones in the vicinity of the
+one near the sawmill. So if the fellow doesn't get caught in one,
+he will in another. I admit it's taking a chance; but what else
+can we do?"
+
+<P>
+"I suppose you're right, Tom. It's like setting a number of
+traps."
+
+<P>
+"Exactly. A trapper can't be sure where he is going to get his
+catch, so he picks out the place, or run-way, where the game has
+been in the habit of coming. He hides his traps about that place,
+and trusts to luck that the animal will blunder into one of them."
+
+<P>
+"Criminals, to my way of thinking, are a good bit like animals.
+They seem to come back to their old haunts. Nearly any police
+story proves this. And it's that on which I am counting to capture
+this criminal. So I'm going to fit up as many telephones with my
+photo and phonograph outfit, as I can in the time we have. You'll
+have to help me. Luckily I've got plenty of selenium plates for
+the sending end. I'll only need one at the receiving end. Now
+we'll have to go and have a talk with the telephone manager, after
+which we'll get busy."
+
+<P>
+"You've overlooked one thing, Tom."
+
+<P>
+"What's that, Ned?"
+
+<P>
+"Why, if you know about which telephone this fellow is going to
+use, why can't you have police stationed near it to capture him as
+soon as he begins to talk?"
+
+<P>
+"Well, I did think of that, Ned; but it won't work."
+
+<P>
+"Why not?"
+
+<P>
+"Because, in the first place this man, or some of his friends,
+will be on the watch. When he goes into the place to telephone
+there'll be a look-out, I'm sure, and he'd either put off talking
+to Mrs. Damon, or he'd escape before we had any evidence against
+him."
+
+<P>
+"You see I've got to get evidence that will stand in the courts to
+convict this fellow, and if he's scared off before we get that,
+the game will be up."
+
+<P>
+"That's what my photo telephone will do--it will get the evidence,
+just as a dictaphone does. In fact, I'm thinking of working it out
+on those lines, after I clear up this business."
+
+<P>
+"Just suppose we had detectives stationed at all the telephones
+near the sawmill, where this fellow would be likely to go. In the
+first place no one has seen him, as far as we know, so there's no
+telling what sort of a chap he is. And you can't go up to a
+perfect stranger and arrest him because you think he is the man
+who has spirited away Mr. Damon."
+
+<P>
+"Another thing. Until this fellow has talked, and made his offer
+to Mrs. Damon, to restore her husband, in exchange for certain
+papers, we have no hold over him."
+
+<P>
+"But he has done that, Tom. You heard him, and you have his voice
+down on the wax cylinder."
+
+<P>
+"Yes, but I haven't had a glimpse of his face. That's what I want,
+and what I'm going to get. Suppose he does go into the telephone
+booth, and tell Mrs. Damon an address where she is to send the
+papers. Even if a detective was near at hand he might not catch
+what was said. Or, if he did, on what ground could he arrest a man
+who, very likely, would be a perfect stranger to him? The
+detective couldn't say: 'I take you into custody for telephoning
+an address to Mrs. Damon.' That, in itself, is no crime."
+
+<P>
+"No, I suppose not," admitted Ned. "You've got this all thought
+out, Tom."
+
+<P>
+"I hope I have. You see it takes quite a combination to get
+evidence against a criminal--evidence that will convict him.
+That's why I have to be so careful in setting my trap."
+
+<P>
+"I see, Tom. Well, it's about time for us to get busy; isn't it?"
+
+<P>
+"It sure is. There's lots to do. First we'll go see the telephone
+people."
+
+<P>
+Tom explained to the 'phone manager the necessity for what he was
+about to do. The manager at once agreed to let the young inventor
+have a free hand. He was much interested in the photo telephone,
+and Tom promised to give his company a chance to use it on their
+lines, later.
+
+<P>
+The telephone near the sawmill was easily located. It was in a
+general store, and the instrument was in a booth. To this
+instrument Tom attached his sending plate, and he also substituted
+for the ordinary incandescent light, a powerful tungsten one, that
+would give illumination enough to cause the likeness to be
+transmitted over the wire.
+
+<P>
+The same thing was done to a number of the public telephones in
+that vicinity, each one being fitted up so that the picture of
+whoever talked would be transmitted over the wire when Tom turned
+the switch. To help the plan further the telephone manager marked
+a number of other 'phones, "Out of Order," for the time being.
+
+<P>
+"Now, I think we're done!" exclaimed the young inventor, with a
+sigh, late that night. He and Ned and the line manager had worked
+hard.
+
+<P>
+"Yes," answered the young banker, "the traps are set. The question
+is: Will our rat be caught?"
+
+
+
+
+
+<P>

+<H3>Chapter XXI The Photo Telephone</H3>
+
+
+<P>
+Tom Swift was taking, as he afterward confessed, "a mighty big
+chance." But it seemed the only way. He was working against
+cunning men, and had to be as cunning as they.
+
+<P>
+True, the man he hoped to capture, through the combination of his
+photo telephone and the phonograph, might go to some other
+instrument than one of those Tom had adjusted. But this could not
+be helped. In all he had put his new attachment on eight 'phones
+in the vicinity of the sawmill. So he had eight chances in his
+favor, and as many against him as there were other telephones in
+use.
+
+<P>
+"It's a mighty small margin in our favor," sighed Tom.
+
+<P>
+"It sure is," agreed Ned. They were at Mrs., Damon's house,
+waiting for the call to come in.
+
+<P>
+"But we couldn't do anything else," went on Tom.
+
+<P>
+"No," spoke Ned, "and I have a great deal of hope in the
+proverbial Swift luck, Tom."
+
+<P>
+"Well, I only hope it holds good this time!" laughed the young
+inventor.
+
+<P>
+"There are a good many things that can go wrong," observed Ned.
+"The least little slip-up may spoil your traps, Tom."
+
+<P>
+"I know it, Ned. But I've got to take the chance. We've just got
+to do something for Mrs. Damon. She's wearing herself out by
+worrying," he added in a low voice, for indeed the wife of his
+friend felt the absence of her husband greatly. She had lost
+flesh, she ate scarcely anything, and her nights were wakeful ones
+of terror.
+
+<P>
+"What if this fails?" asked Ned.
+
+<P>
+"Then I'm going to work that button clew to the limit," replied
+Tom. "I'll go to Boylan and see what he and Peters have to say."
+
+<P>
+"If you'd done as I suggested you'd have gone to them first,"
+spoke Ned. "You'll find they're mixed up in this."
+
+<P>
+"Maybe; but I doubt it. I tell you there isn't a clew leading to
+Peters--as yet."
+
+<P>
+"But there will be," insisted Ned. "You'll see that that I'm right
+this time."
+
+<P>
+"I can't see it, Ned. As a matter of fact, I would have gone to
+Boylan about that button I found in my airship only I've been so
+busy on this photo telephone, and in arranging the trap, that I
+haven't had time. But if this fails--and I'm hoping it won't--I'll
+get after him," and there was a grim look on the young inventor's
+face.
+
+<P>
+It was wearying and nervous work--this waiting. Tom and Ned felt
+the strain as they sat there in Mrs. Damon's library, near the
+telephone. It had been fitted up in readiness. Attached to the
+receiving wires was a sensitive plate, on which Tom hoped would be
+imprinted the image of the man at the other end of the wire--the
+criminal who, in exchange for the valuable land papers, would give
+Mr. Damon his liberty.
+
+<P>
+There was also the phonograph cylinder to record the man's voice.
+Several times, while waiting for the call to come in, Tom got up
+to test the apparatus. It was in perfect working order.
+
+<P>
+As before, there was an extension telephone, so that Mrs. Damon
+could talk to the unknown, while Tom could hear as well. But he
+planned to take no part in the conversation unless something
+unforeseen occurred.
+
+<P>
+Mr. Damon was an enthusiastic photographer, and he had a dark room
+adjoining his library. It was in this dark room that Tom planned
+to develop the photo telephone plate.
+
+<P>
+On this occasion he was not going to use the metal plate in which,
+ordinarily, the image of the person talking appeared. That record
+was but a fleeting one, as in a mirror. This time Tom wanted a
+permanent picture that could, if necessary, be used in a court of
+justice.
+
+<P>
+Tom's plan was this: If the person who had demanded the papers
+came to one of the photo telephones, and spoke to Mrs. Damon, Tom
+would switch on the receiving apparatus. Thus, while the man was
+talking, his picture would be taken, though he would not know of
+the thing being done.
+
+<P>
+His voice would also be recorded on the wax cylinder, and he would
+be equally unaware of this.
+
+<P>
+When Tom had imprinted the fellow's image on the prepared plate,
+he would go quickly to the dark room and develop it. A wet print
+could be made, and with this as evidence, and to use in
+identification, a quick trip could be made to the place whence the
+man had telephoned. Tom hoped thus to capture him.
+
+<P>
+To this end he had his airship in waiting, and as soon as he had
+developed the picture he planned to rush off to the vicinity of
+the sawmill, and make a prisoner of the man whose features would
+be revealed to him over the wire.
+
+<P>
+It was a hazardous plan--a risky one--but it was the best that he
+could evolve. Tom had instructed Mrs. Damon to keep the man in
+conversation as long as possible, in order to give the young
+inventor himself time to rush off in his airship. But of course
+the man might get suspicious and leave. That was another chance
+that had to be taken.
+
+<P>
+"If I had thought of it in time," said Tom, musingly, as he paced
+up and down in the library waiting for the 'phone to ring, "if I
+had thought of it in time I would have rigged up two plates--one
+for a temporary, or looking-glass, picture, and the other for a
+permanent one. In that way I could rush off as soon as I got a
+glimpse of the fellow. But it's too late to do that now. I'll have
+to develop this plate."
+
+<P>
+Waiting is the most wearisome work there is. Tom and Ned found
+this to be the case, as they sat there, hoping each moment that
+the telephone bell would ring, and that the man at the other end
+of the wire would be the mysterious stranger. Mrs. Damon, too,
+felt the nervous strain.
+
+<P>
+"This is about the hour he called up yesterday," said Tom, in a
+low voice, after coming back from a trip to the window to see that
+his airship was in readiness. He had brought over to help in
+starting it, for he was using his most powerful and speedy craft,
+and the propellers were hard to turn.
+
+<P>
+"Yes," answered Mrs. Damon. "It was just about this hour, Tom. Oh,
+I do hope--"
+
+<P>
+She was interrupted by the jingle of the telephone bell. With a
+jump Tom was at the auxiliary instrument, while Mrs. Damon lifted
+off the receiver of her own telephone.
+
+<P>
+"Yes; what is it?" she asked, in a voice that she tried to make
+calm.
+
+<P>
+"Do you know who this is?" Tom heard come over the wire.
+
+<P>
+"Are you the--er--the person who was to give me an address where I
+am to send certain papers?"
+
+<P>
+"Yes. I'm the same one. I'm glad to see that you have acted
+sensibly. If I get the papers all right, you'll soon have your
+husband back. Now do as I say. Take down this address."
+
+<P>
+"Very well," assented Mrs. Damon. She looked over at Tom. He was
+intently listening, and he, too, would note the address given. The
+trap was about to be sprung. The game had walked into it. Just
+which telephone was being used Tom could not as yet tell. It was
+evidently not the one nearest the planing mill, for Tom could not
+hear the buzzing sound. It was well he had put his attachment on
+several instruments.
+
+<P>
+"One moment, please," said Mrs. Damon, to the unknown at the other
+end of the wire. This was in accordance with the pre-arranged
+plan.
+
+<P>
+"Well, what is it?" asked the man, impatiently. "I have no time to
+waste."
+
+<P>
+Tom heard again the same gruff tones, and he tried in vain to
+recognize them.
+
+<P>
+"I want you take down a message to Mr. Damon," said his wife.
+"This is very important. It can do you no harm to give him this
+message; but I want you to get it exact. If you do not promise to
+deliver it I shall call all negotiations off."
+
+<P>
+"Oh, all right I'll take the message; but be quick about it. Then
+I'll give you the address where you are to send the papers."
+
+<P>
+"This is the message," went on Mrs. Damon. "Please write it down.
+It is very important to me. Have you a pencil?"
+
+<P>
+"Yes, I have one. Wait until I get a bit of paper. It's so dark in
+this booth--wait until I turn on the light."
+
+<P>
+Tom could not repress a pleased and joyful exclamation. It was
+just what he had hoped the man would do--turn on the light in the
+booth. Indeed, it was necessary for the success of the trap that
+the light be switched on. Otherwise no picture could be
+transmitted over the wire. And the plan of having the man write
+down a message to Mr. Damon was arranged with that end in view.
+The man would need a light to see to write, and Tom's apparatus
+must be lighted in order to make it work. The plot was coming
+along finely.
+
+<P>
+"There!" exclaimed the man at the other end of the wire. "I have a
+light now. Go ahead with your message, Mrs. Damon. But make it
+short. I can't stay here long."
+
+<P>
+Then Mrs. Damon began dictating the message she and Tom had agreed
+upon. It was as long as they dared make it, for they wanted to
+keep the man in the booth to the last second.
+
+<P>
+"Dear Husband," began Mrs. Damon. What the message was does not
+matter. It has nothing to do with this story. Sufficient to say
+that the moment the man began writing it down, as Tom could tell
+over the sensitive wire, by the scratching of the pencil--at that
+moment Tom, knowing the light was on in the distant telephone
+booth, switched on the picture-taking apparatus. His receiving
+apparatus at once indicated that the image was being made on the
+sensitive plate.
+
+<P>
+It took only a few seconds of time, and with the plate in the
+holder Tom hastened to the dark room to develop it. Ned took his
+chum's place at the telephone, to see that all worked smoothly.
+The photo telephone had done it's work. Whose image would be found
+imprinted on the sensitive plate? Tom's hands trembled so that he
+could scarcely put it in the developing solution.

+Ned Newton, listening at the auxiliary telephone heard the man, to
+whom Mrs. Damon was dictating her message to her husband, utter an
+exclamation of impatience.
+
+<P>
+"I'm afraid I can't take down any more," he called. "That is
+enough. Now you listen. I want you to send me those papers."
+
+<P>
+"And I am willing to," went on Mrs. Damon, while Ned listened to
+the talk, the phonograph faithfully recording it.
+
+<P>
+"I wonder whose picture Tom will find," mused Ned.
+
+<P>
+The unknown, at the other end of the wire, began giving Mrs. Damon
+a description of just what papers he wanted, and how to mail them
+to him. He gave an address that Ned recognized as that of a cigar
+store, where many persons received their mail under assumed names.
+The postal authorities had, for a long time, tried to get evidence
+against it
+
+<P>
+"That's going to make it hard to get him, when he comes for the
+papers," thought Ned. "He's a foxy criminal, all right. But I
+guess Tom will turn the trick."
+
+<P>
+Mrs. Damon was carefully noting down the address. She really
+intended to send the papers, if it proved that there was no other
+way in which she could secure the release of her husband. But she
+did not count on all of Tom's plans. "Why doesn't he develop that
+plate?" thought Ned. "He'll be too late, in spite of his airship.
+That fellow will skip."
+
+<P>
+It was at that moment that Tom came into the library. He moved
+cautiously, for he realized that a loud sound in the room would
+carry to the man at the other end of the wire. Tom motioned for
+Ned to come to him. He held out a dripping photographic plate.
+
+<P>
+"It's Peters!" said Tom, in a hoarse whisper.
+
+<P>
+"Peters?" gasped Ned. "How could it be? His voice--"
+
+<P>
+"I know. It didn't sound a bit like Peters over the 'phone, but
+there's his picture, all right!"
+
+<P>
+Tom held up the plate. There, imprinted on it by the wonderful
+power of the young inventor's latest appliance, was the image of
+the rascally promoter. As plainly as in life he was shown, even to
+his silk hat and the flower in his button-hole. He was in a
+telephone booth--that much could be told from the photograph that
+had been transmitted over the wire, but which booth could not be
+said--they were nearly all alike.
+
+<P>
+"Peters!" gasped Ned. "I thought he was the fellow, Tom."
+
+<P>
+"Yes, I know. You were right, and I was wrong. But I did not
+recognize his voice. It was very hoarse. He must have a bad cold."
+Later this was learned to have been the case. "There's no time to
+lose," whispered Tom, while Mrs. Damon was doing her best to
+prolong the conversation in order to hold the man at the other end
+of the wire. "Ned, get central on the other telephone, and see
+where this call came from. Then we'll get there as fast as the
+airship will take us."
+
+<P>
+A second and temporary telephone line had been installed in the
+Damon home, and on this Ned was soon talking, while Tom, putting
+the photographic plate away for future use, rushed out to get his
+airship in shape for a quick flight. He had modified his plans.
+Instead of having a detective take a print of the photo telephone
+image, and make the arrest, Tom was going to try to capture Peters
+himself. He believed he could do it. One look at the wet plate was
+enough. He knew Peters, though it upset some of his theories to
+learn that it was the promoter who was responsible for Mr. Damon's
+disappearance.
+
+<P>
+The man at the other end of the wire was evidently getting
+impatient. Possibly he suspected some trick. "I've got to go now,"
+he called to Mrs. Damon. "If I don't get those papers in the
+morning it will be the worse for Mr. Damon."
+
+<P>
+"Oh, I'll send you the papers," she said.
+
+<P>
+By this time Ned had gotten into communication with the manager of
+the central telephone exchange, and had learned the location of
+the instrument Peters was using. It was about a mile from the one
+near the sawmill.
+
+<P>
+"Come on!" called Tom to his chum, as the latter gave him this
+information. "The Firefly is tuned up for a hundred miles an hour!
+We'll be there in ten minutes! We must catch him red-handed, if
+possible!"
+
+<P>
+"He's gone!" gasped Mrs. Damon as she came to the outer door, and
+watched Tom and Ned taking their places in the airship, while Koku
+prepared to twirl the propellers.
+
+<P>
+"Gone!" echoed Tom, blankly.
+
+<P>
+"Yes, he hung up the receiver."
+
+<P>
+"See if you can't get him back," suggested the young inventor.
+"Ask Central to ring that number again. We'll be there in a jiffy.
+Maybe he'll come to the telephone again. Or he may even call up
+his partners and tell them the game is working his way. Try to get
+him back, Mrs. Damon."
+
+<P>
+"I will," she said.
+
+<P>
+And, as she hurried back to the instrument, Tom and Ned shot up
+toward the blue sky in an endeavor to capture the man at the other
+telephone.
+
+<P>
+"And to think it was Peters!" cried Tom into Ned's ear, shouting
+to be heard above the roar of the motor exhaust.
+
+<P>
+"I thought he'd turn out to be mixed up in the affair," said Ned.
+
+<P>
+"Well, you were right. I was off, that time," admitted Tom, as he
+guided his powerful craft above the trees. "I was willing to admit
+that he had something to do with Mr. Damon's financial trouble,
+but as for kidnapping him--well, you never can tell."
+
+<P>
+They drove on at a breath-catching pace, and it seemed hardly a
+minute after leaving Mrs. Damon's house before Tom called:
+
+<P>
+"There's the building where the telephone is located."
+
+<P>
+"And now for that rascal Peters!" cried Ned.
+
+<P>
+The airship swooped down, to the great astonishment of some
+workmen nearby.
+
+<P>
+Hardly had the wheels ceased revolving on the ground, as Tom made
+a quick landing, than he was out of his seat, and running toward
+the telephone. He knew the place at once from having heard Ned's
+description, and besides, this was one of the places where he had
+installed his apparatus.
+
+<P>
+Into the store Tom burst, and made a rush for the 'phone booth. He
+threw open the door. The place was empty!
+
+<P>
+"The man--the man who was telephoning!" Tom called to the
+proprietor of the place.
+
+<P>
+"You mean that big man, with the tall hat, who was in there so
+long?"
+
+<P>
+"Yes, where is he?"
+
+<P>
+"Gone. About two minutes ago."
+
+<P>
+"Which way?"
+
+<P>
+"Over toward Shopton, and in one of the fastest autos that ever
+scattered dust in this section."
+
+<P>
+"He's escaped us!" said Tom to Ned. "But we'll get him yet! Come
+on!"
+
+<P>
+"I'm with you. Say, do you know what this looks like to me?"
+
+<P>
+"What?"
+
+<P>
+"It looks as if Peters was scared and was going to run away to
+stay!"
+
+
+

+<A NAME="XXIII"></A>
+<H3>Chapter XXIII On The Trail</H3>
+
+
+<P>
+Such a crowd had quickly gathered about Tom's airship that it was
+impossible to start it. Men and boys, and even some girls and
+women, coming from no one knew where, stood about the machine,
+making wondering remarks about it.
+
+<P>
+"Stand back, if you please!" cried Tom, good-naturedly. "We've
+got to get after the fellow in the auto."
+
+<P>
+"You'll have hard work catching him, friend, in that rig,"
+remarked a man. "He was fracturing all the speed laws ever passed.
+I reckon he was going nigh onto sixty miles an hour."
+
+<P>
+"We can make a hundred," spoke Ned, quietly.
+
+<P>
+"A hundred! Get out!" cried the man. "Nothing can go as fast as
+that!"
+
+<P>
+"We'll show you, if we once get started," said Tom. "I guess we'll
+have to get one of these fellows to twirl the propellers for us,
+Ned," he added. "I didn't think, or I'd have brought the selfstarting
+machine," for this one of Tom's had to be started by
+someone turning over the propellers, once or twice, to enable the
+motor to begin to speed. On some of his aircraft the young
+inventor had attached a starter, something like the ones on the
+newest autos.
+
+<P>
+"What are you going to do?" asked Ned, as Tom looked to the
+priming of the cylinders.
+
+<P>
+"I'm going to get on the trail of Peters," he said. "He's at the
+bottom of the whole business; and it's a surprise to me. I'm going
+to trail him right down to the ground now, and make him give up
+Mr. Damon and his fortune,"
+
+<P>
+"But you don't know where he is, Tom."
+
+<P>
+"I'll find out. He isn't such an easy man to miss--he's too
+conspicuous. Besides, if he's just left in his auto we may catch
+him before he gets to Shopton."
+
+<P>
+"Do you think he's going there?"
+
+<P>
+"I think so. And I think, Ned, that he's become suspicious and
+will light out. Something must have happened, while he was
+telephoning, and he got frightened, as big a bluff as he is. But
+we'll get him. Come on! Will you turn over the propellers, please?
+I'll show you how to do it," Tom went on to a big, strong man
+standing close to the blades.
+
+<P>
+"Sure I'll do it," was the answer. "I was a helper once at an
+airship meet, and I know how."
+
+<P>
+"Get back out of the way in time," the young inventor warned him.
+"They start very suddenly, sometimes."
+
+<P>
+"All right, friend, I'll watch out," was the reply, and with Tom
+and Ned in their seats, the former at the steering wheel, the
+craft of the air was soon throbbing and trembling under the first
+turn, for the cylinders were still warm from the run from Mrs.
+Damon's house.
+
+<P>
+The telephone was in an outlying section of Waterford--a section
+devoted in the main to shops and factories, and the homes of those
+employed in various lines of manufacture. Peters had chosen his
+place well, for there were many roads leading to and from this
+section, and he could easily make his escape.
+
+<P>
+"But we'll get after him," thought Tom, grimly, as he let the
+airship run down the straight road a short distance on the bicycle
+wheels, to give it momentum enough so that it would rise.
+
+<P>
+Then, with the tilting of the elevation rudder, the craft rose
+gracefully, amid admiring cheers from the crowd. Tom did not go up
+very far, as he wanted to hover near the ground, to pick out the
+speeding auto containing Peters.
+
+<P>
+But this time luck was not with Tom. He and Ned did sight a number
+of cars speeding along the highway toward Shopton, but when they
+got near enough to observe the occupants they were disappointed
+not to behold the man they sought. Tom circled about for some
+time, but it was of no use, and then he headed his craft back
+toward Waterford.
+
+<P>
+"Where are you going?" asked Ned, yelling the words into the ear
+of his chum.
+
+<P>
+"Back to Mrs. Damon's," answered Tom, in equally loud tones.
+
+<P>
+It was impossible to talk above the roaring and throbbing of the
+motor, so the two lads kept silent until the airship had landed
+near Mrs. Damon's home.
+
+<P>
+"I want to see if Mrs. Damon is all right," Tom explained, as he
+jumped from the still moving machine. "Then we'll go to Shopton,
+and cause Peters's arrest. I can make a charge against him now,
+and the evidence of the photo telephone will convict him, I'm
+sure. And I also want to see if Mrs. Damon has had any other
+word."
+
+<P>
+She had not, however, though she was more nervous and worried than
+ever.
+
+<P>
+"Oh, Tom, what shall I do?" she exclaimed. "I am so frightened!
+What do you suppose they will do to Mr. Damon?"
+
+<P>
+"Nothing at all!" Tom assured her. "He will be all right. I think
+matters are coming to a crisis now, and very likely he'll be with
+you inside of twenty-four hours. The game is up, and I guess
+Peters knows it. I'm going to have him arrested at once."
+
+<P>
+"Shall I send those land papers, Tom?"
+
+<P>
+"Indeed you must not! But I'll talk to you about that later. Just
+put away that phonograph record of Peters's talk. I'll take along
+the photo telephone negative, and have some prints made--or, I
+guess, since we're going in the airship, that I'd better leave it
+here for the present. We'll use it as evidence against Peters.
+Come on, Ned."
+
+<P>
+"Where to now?"
+
+<P>
+"Peters's house. He's probably there, arranging to cover up his
+tracks when he lights out."
+
+<P>
+But Shallock Peters did better than merely cover up his tracks. He
+covered himself up, so to speak. For when Ned and Tom, after a
+quick flight in the airship, reached his house, the promoter had
+left, and the servants, who were quite excited, did not know where
+he had gone.
+
+<P>
+"He just packed up a few clothes and ran out," said one of the
+maids. "He didn't say anything about our wages, either, and he
+owes me over a month."
+
+<P>
+"Me too," said another.
+
+<P>
+"Well, if he doesn't pay me some of my back wages soon, I'll sue
+him!" declared the gardener. "He owes me more than three months,
+but he kept putting me off."
+
+<P>
+And, so it seemed, Peters had done with several of his employes.
+When the promoter came to Shopton he had taken an elaborate house
+and engaged a staff of servants. Peters was not married, but he
+gave a number of entertainments to which the wealthy men of
+Shopton and their wives came. Later it was found that the bills
+for these had never been paid. In short, Peters was a "bluff" in
+more ways than one.
+
+<P>
+Tom told enough of his story to the servants to get them on his
+side. Indeed, now that their employer had gone, and under such
+queer circumstances, they had no sympathy for him. They were only
+concerned about their own money, and Tom was given admittance to
+the house.
+
+<P>
+Tom made a casual search, hoping to find some clew to the
+whereabouts of Mr. Damon, or to get some papers that would save
+his fortune. But the search was unsuccessful.
+
+<P>
+There was a safe in the room Peters used for an office, but when
+Tom got there the strong box was open, and only some worthless
+documents remained.
+
+<P>
+"He smelled a rat, all right," said Tom, grimly. "After he
+telephoned to Mrs. Damon something happened that gave him an
+intimation that someone was after him. So he got away as soon as
+he could."
+
+<P>
+"But what are you going to do about it, Tom?"
+
+<P>
+"Get right after him. He can't have gotten very far. I want him
+and I want Boylan. We're getting close to the end of the trail,
+Ned."
+
+<P>
+"Yes, but we haven't found Mr. Damon yet, and his fortune seems to
+have vanished."
+
+<P>
+"Well, we'll do the best we can," said Tom, grimly. "Now I'm going
+to get a warrant for the arrest of Peters, and one for Boylan, and
+I'm going to get myself appointed a special officer with power to
+serve them. We've got our work cut out for us, Ned."
+
+<P>
+"Well, I'm with you to the end."
+
+<P>
+"I know you are!" cried Tom.
+
+
+
+
+
+<P>
+<A NAME="XXIV"></A>
+<H3>Chapter XXIV The Lonely House</H3>
+
+
+<P>
+The young inventor had little difficulty in getting the warrants
+he sought. In the case of Boylan, who seemed to be Peters's righthand
+man, when it came to criminal work, Tom made a charge of
+unlawfully taking the airship. This would be enough to hold the
+man on until other evidence could be obtained against him.
+
+<P>
+As for Peters, he was accused of taking certain valuable bonds and
+stocks belonging to Mr. Damon. Mrs. Damon gave the necessary
+evidence in this case, and the authorities were told that later,
+when Peters should have been arrested, other evidence so
+skillfully gotten by Tom's photo telephone, would be brought
+before the court.
+
+<P>
+"It's a new way of convicting a man--by a photo telephone--but I
+guess it's a good one," said the judge who signed the warrants.
+
+<P>
+"Well, now that we've got what we want, the next thing to do is to
+get the men--Peters, and the others," said Tom, as he and Ned sat
+in Tom's library after several hours of strenuous work.
+
+<P>
+"How are you going to start?" the young banker wanted to know. "It
+seems a strange thing that a man like Mr. Damon could be made away
+with, and kept in hiding so long without something being heard of
+him. I'm afraid, Tom, that something must have happened to him."
+
+<P>
+"I think so too, Ned. Nothing serious, though," Tom added,
+quickly, as he saw the look of alarm on his chum's face. "I think
+Mr. Damon at first went away of his own accord."
+
+<P>
+"Of his own accord?"
+
+<P>
+"Yes. I think Peters induced him to go with him, on the pretense
+that he could recover his fortune. After getting Mr. Damon in
+their power they kept him, probably to get the rest of his fortune
+away from him."
+
+<P>
+"But you stopped that, Tom," said Ned, proud of his chum's
+abilities.
+
+<P>
+"Well, I hope so," admitted the young inventor. "But I've still
+got plenty to do."
+
+<P>
+"Have you a starting point?"
+
+<P>
+"For one thing," Tom answered, "I'm going to have Mrs. Damon mail
+a fake package to the address Peters gave. If he, or any of his
+men, call for it, we'll have a detective on the watch, and arrest
+them."
+
+<P>
+"Good!"
+
+<P>
+"Of course it may not work," spoke Tom; "but it's something to
+try, and we can't miss any chances."
+
+<P>
+Accordingly, the next day, a package containing only blank paper,
+made up to represent the documents demanded by Peters as the price
+of releasing Mr. Damon, was mailed to the address Mrs. Damon had
+received over the wire from the rascally promoter. Then a private
+detective was engaged to be on the watch, to take into custody
+whoever called for the bundle. Tom, though, had not much hope of
+anything coming of this, as it was evident that Peters had taken
+the alarm, and left.
+
+<P>
+"And now," said Tom, when he had safely put away the wax record,
+containing the incriminating talk of Peters, and had printed
+several photographs, so wonderfully taken over the wire, "now to
+get on the trail again."
+
+<P>
+It was not an easy one to follow. Tom began at the deserted home
+of the alleged financier. The establishment was broken up, for
+many tradesmen came with bills that had not been paid, and some of
+them levied on what little personal property there was to satisfy
+their claims. The servants left, sorrowful enough over their
+missing wages. The place was closed up under the sheriff's orders.
+
+<P>
+But of Peters and his men not a trace could be found. Tom and Ned
+traveled all over the surrounding country, looking for clews, but
+in vain. They made several trips in the airship, but finally
+decided that an automobile was more practical for their work, and
+kept to that.
+
+<P>
+They did find some traces of Peters. As Tom had said, the man was
+too prominent not to be noticed. He might have disguised himself,
+though it seemed that the promoter was a proud man, and liked to
+be seen in flashy clothes, a silk hat, and with a buttonhole
+bouquet.
+
+<P>
+This made it easy to get the first trace of him. He had been seen
+to take a train at the Shopton station, though he had not bought a
+ticket. The promoter had paid his fare to Branchford, a junction
+point, but there all trace of him was lost. It was not even
+certain that he went there.
+
+<P>
+"He may have done that to throw us off," said Tom. "Just because
+he paid his way to Branchford, doesn't say he went there. He may
+have gotten off at the next station beyond Shopton."
+
+<P>
+"Do you think he's still lingering around here?" asked Ned.
+
+<P>
+"I shouldn't be surprised," was Tom's answer. "He knows that there
+is still some of the Damon property left, and he is probably
+hungry for that. We'll get him yet, Ned."
+
+<P>
+But at the end of several days Tom's hopes did not seem in a fair
+way to be realized. He and Ned followed one useless clew after
+another. All the trails seemed blind ones. But Tom never gave up.
+
+<P>
+He was devoting all his time now to the finding of his friend Mr.
+Damon, and to the recovery of his fortune. In fact the latter was
+not so important to Tom as was the former. For Mrs. Damon was on
+the verge of a nervous collapse on account of the absence of her
+husband.
+
+<P>
+"If I could only have some word from him, Tom!" she cried,
+helplessly.
+
+<P>
+To Tom the matter was very puzzling. It seemed utterly impossible
+that Mr. Damon could be kept so close a prisoner that he could not
+manage to get some word to his friends. It was not as if he was a
+child. He was a man of more than ordinary abilities. Surely he
+might find a way to outwit his enemies.
+
+<P>
+But the days passed, and no word came. A number of detectives had
+been employed, but they were no more successful than Tom. The
+latter had given up his inventive work, for the time being, to
+devote all his time to the solution of the mystery.
+
+<P>
+Tom and Ned had been away from Shopton for three days, following
+the most promising clew they had yet received. But it had failed
+at the end, and one afternoon they found themselves in a small
+town, about a hundred miles from Shopton. They had been motoring.
+
+<P>
+"I think I'll call up the house," said Tom. "Dad may have received
+some news, or Mrs. Damon may have sent him some word. I'll get my
+father on the wire."
+
+<P>
+Connection to Tom's house was soon made, and Ned, who was
+listening to his chum's remarks, was startled to hear him cry out:
+
+<P>
+"What's that you say? My airship taken again? When did it happen?
+Yes, I'm listening. Go on, Father!"
+
+<P>
+Then followed a silence while Tom listened, breaking in now and
+then with an excited remark, Suddenly he called:
+
+<P>
+"Good-by, Dad! I'm coming right home!"
+
+<P>
+Tom hung up the receiver with a bang, and turned to his chum.
+
+<P>
+"What do you think!" he cried. "The <i>Eagle</i> was taken again last
+night! The same way as before. Nobody got a glimpse of the
+thieves, though. Dad has been trying to get in communication with
+me ever since. I'm glad I called up. Now we'll get right back to
+Shopton, and see what we can do. This is the limit! Peters and his
+crowd will be kidnapping us, next."
+
+<P>
+"That's right," agreed Ned.
+
+<P>
+He and Tom were soon off again, speeding in the auto toward
+Shopton. But the roads were bad, after a heavy rain, and they did
+not make fast time.
+
+<P>
+The coming of dusk found them with more than thirty miles to go.
+They were in an almost deserted section of the country when
+suddenly, as they were running slowly up a hill, there was a
+sudden crack, the auto gave a lurch to one side of the roadway and
+then settled heavily. Tom clapped on both brakes quickly, and gave
+a cry of dismay.
+
+<P>
+"Broken front axle!" he said. "We're dished, Ned!"
+
+<P>
+They got out, being no more harmed than by the jolting. The car
+was out of commission. The two chums looked around Except for a
+lonely house, that bore every mark of being deserted, not a
+dwelling was in sight where they might ask for aid or shelter.
+
+<P>
+And, as they looked, from that lonely house came a strange cry--a
+cry as though for help!
+
+
+
+
+
+<P>
+<A NAME="XXV"></A>
+<H3>Chapter XXV The Airship Capture</H3>
+
+
+<P>
+"Did you hear that?" cried Ned.
+
+<P>
+"I certainly did," answered Tom. "What was it."
+
+<P>
+"Sounded to me like a cry of some sort."
+
+<P>
+"It was. An animal, I'd say."
+
+<P>
+The two chums moved away from the broken auto, and looked at each
+other. Then, by a common impulse, they started toward the lonely
+house, which was set back some distance from the road.
+
+<P>
+"Let's see who it was," suggested Tom, "After all, though it looks
+deserted, there may be someone in the house, and we've got to have
+some kind of help. I don't want to leave my car on the road all
+night, though it will have to be repaired before I can use it
+again."
+
+<P>
+"It sure is a bad break," agreed Ned.
+
+<P>
+As they walked toward the deserted house they heard the strange
+cry again. It was louder this time, and following it the boys
+heard a sound as if a blow had been struck.
+
+<P>
+"Someone is being attacked!" cried Tom. "Maybe some poor tramp has
+taken shelter in there and a dog is after them. Come on, Ned,
+we've got to help!"
+
+<P>
+They started on a run for the lonely house, but while still some
+distance away a curious thing happened.
+
+<P>
+There was a sudden cry--an appeal for help it seemed--but this
+time in the open. And, as Tom and Ned looked, they saw several men
+running from the rear of the old house. Between them they carried
+an inert form,
+
+<P>
+"Something's wrong!" exclaimed Tom, "There's crooked work going on
+here, Ned."
+
+<P>
+"You're right! It's up to us to stop it! Come on!"
+
+<P>
+But before the boys had taken half a dozen more steps they heard
+that which caused them great surprise. For from a shed behind the
+house came the unmistakable throb and roar of a motor.
+
+<P>
+"They're going off in an auto!" cried Ned.
+
+<P>
+"And they're carrying someone with them!" exclaimed Tom.
+
+<P>
+By this time they had gotten to a point where they could see the
+shed, and what was their astonishment to see being rolled from it
+a big biplane. At the sight of it Tom cried:
+
+<P>
+"It's the <i>Eagle</i>! That's my airship, Ned!"
+
+<P>
+"You're right! How did it get here?"
+
+<P>
+"That's for us to find out. I shouldn't wonder, Ned, but what
+we're at last on the trail of Peters and his crowd!"
+
+<P>
+The men--there were four or five of them, Ned guessed--now broke
+into a run, still carrying among them the inert form of another.
+The cries for help had ceased, and it seemed as if the unfortunate
+one was unconscious.
+
+<P>
+A moment later, and before the boys could do anything, had they
+the power, the men fairly jumped aboard Tom Swift's biggest
+airship. The unconscious one was carried with them.
+
+<P>
+Then the motor was speeded up. The roar and throbbing were almost
+deafening.
+
+<P>
+"Stop that! Hold on! That's my machine!" yelled Tom.
+
+<P>
+He might as well have spoken to the wind. With a rush and a roar
+the big <i>Eagle</i> shot away and upward, carrying the men and their
+mysterious, unconscious companion. It was getting too dark for Tom
+and Ned to make out the forms or features of the strangers.
+
+<P>
+"We're too late!" said Ned, hopelessly.
+
+<P>
+"Yes, they got away," agreed Tom. "Oh, if only I had my speedy
+little monoplane!"
+
+<P>
+"But who can they be? How did your airship get here? And who is
+that man they carried out of the house?" cried Ned.
+
+<P>
+"I don't know the last--maybe one of their crowd who was injured
+in a fight."
+
+<P>
+"What crowd?"
+
+<P>
+"The Peters gang, of course. Can't you see it, Ned?"
+
+<P>
+Unable to do anything, the two youths watched the flight of the
+<i>Eagle</i>. She did not move at her usual speed, for she was carrying
+too heavy a load.
+
+<P>
+Presently from the air overhead, and slightly behind them, the
+boys heard the sound of another motor. They turned quickly.
+
+<P>
+"Look!" cried Ned. "Another airship, by all that's wonderful!"
+
+<P>
+"If we could only stop them!" exclaimed Tom. "That's a big
+machine, and they could take us aboard. Then we could chase the
+<i>Eagle</i>. We could catch her, too, for she's overloaded!"
+
+<P>
+Frantically he and Tom waved their caps at the man who was now
+almost overhead in his airship. The boys did not call. They well
+knew, with the noise of the motor, the occupant of the airship
+could not hear them. But they waved and pointed to the slowly-moving
+<i>Eagle</i>.
+
+<P>
+To their surprise and delight the man above them shut off his
+engine, and seemed about to come down. Then Tom cried, knowing he
+could be heard:
+
+<P>
+"Help us capture that airship? It's mine and they've stolen it!"
+
+<P>
+"All right! Be with you in a minute!" came back the answer from
+above.
+
+<P>
+The second biplane came down to earth, ands as it ceased running
+along on its bicycle wheels, the occupant jumped out.
+
+<P>
+"Hello, Tom Swift!" he called, as he took off his goggles.
+
+<P>
+"Why--why it's Mr. Halling!" cried the young inventor, in delight,
+recognizing the birdman who had brought him the first news of Mr.
+Damon's trouble, the day the airship became entangled in the
+aerials of the wireless on Tom's house.
+
+<P>
+"What are you doing here, Tom?" asked Mr. Hailing. "What has
+happened?"
+
+<P>
+"We're looking for Mr. Damon. That's a bad crowd there," and he
+pointed toward the other aircraft. "They have my <i>Eagle</i>. Can you
+help me catch them?"
+
+<P>
+"I certainly can--and will! Get aboard! I can carry four."
+
+<P>
+"Then you have a new machine?"
+
+<P>
+"Yes, and a dandy! All the latest improvements--self-starter and
+all! I'm glad of a chance to show it to you."
+
+<P>
+"And I'm glad, too!" cried Tom. "It was providential that you
+happened along. What were you doing here?"
+
+<P>
+"Just out on a trial spin. But come on, if we're going to catch
+those fellows!"
+
+<P>
+Quickly Tom, Ned, and Mr. Halling climbed into the seats of the
+new airship. It was started from a switch, and in a few seconds it
+was on the wing, chasing after the <i>Eagle</i>.
+
+<P>
+Then began a strange race, a race in the air after the unknown
+strangers who had Tom's machine. Had the <i>Eagle</i> not been so heavily
+laden it might have escaped, for Tom's craft was a speedy one. But
+this time it had to give the palm to Mr. Grant Halling's. Faster
+and faster in pursuit flew the <i>Star</i>, as the new craft was called.
+Faster and faster, until at last, coming directly over the <i>Eagle</i>,
+Mr. Halling sent his craft down in such a manner as to "blanket"
+the other. In an instant she began to sink, and with cries of
+alarm the men shut off the motor and started to volplane to the
+earth.
+
+<P>
+But they made an unskillful landing. The <i>Eagle</i> tilted to one side,
+and came down with a crash. There were cries of pain, then
+silence, and a few seconds later two men ran away from the
+disabled airship. But there were three senseless forms on the
+ground beside the craft when Tom, Ned and Mr. Halling ran up. In
+the fading light Tom saw a face he knew--three faces in fact.
+
+<P>
+"Mr. Damon!" he cried. "We've found him, Ned!"
+
+<P>
+"But--too late--maybe!" answered Ned, in a low voice, as he, too,
+recognized the man who had been missing so long.
+
+<P>
+Mr. Halling was bending over the unconscious form of his friend.
+
+<P>
+"He's alive!" he cried, joyfully. "And not much hurt, either. But
+he has been ill, and looks half starved. Who are these men?"
+
+<P>
+Tom gave a hasty look.
+
+<P>
+"Shallock Peters and Harrison Boylan!" he cried. "Ned, at last
+we've caught the scoundrels!"
+
+<P>
+It was true. Chance had played into the hands of Tom Swift. While
+Mr. Halling was looking after Mr. Damon, reviving him, the young
+inventor and Ned quickly bound the hands and feet of the two
+plotters with pieces of wire from the broken airship.
+
+<P>
+Presently Mr. Damon opened his eyes.
+
+<P>
+"Where am I? What happened? Oh, bless my watch chain--it's Tom
+Swift! Bless my cigar case, I--"
+
+<P>
+"He's all right!" cried Tom, joyfully. "When Mr. Damon blesses
+something beside his tombstone he's all right."
+
+<P>
+Peters and Boylan soon revived, both being merely stunned, as was
+Mr. Damon. They looked about in wonder, and then, feeling that
+they were prisoners, resigned themselves to their fate. Both men
+were shabbily dressed, and Tom would hardly have known the once
+spick and span Mr. Peters. He had no rose in his buttonhole now.
+
+<P>
+"Well, you have me, I see," he said, coolly. "I was afraid we were
+playing for too high a stake."
+
+<P>
+"Yes, we've got you," replied Tom,
+
+<P>
+"But you can't prove much against me," went on Peters. "I'll deny
+everything."
+
+<P>
+"We'll see about that," added the young inventor, grimly, and
+thought of the picture in the plate and the record on the wax
+cylinder.
+
+<P>
+"We've got to get Mr. Damon to some place where he can be looked
+after," broke in Mr. Halling. "Then we'll hear the story."
+
+<P>
+A passing farmer was prevailed on to take the party in his big
+wagon to the nearest town, Mr. Hailing going on ahead in his
+airship. Tom's craft could not be moved, being badly damaged.
+
+<P>
+Once in town Peters and Boylan were put in jail, on the charges
+for which Tom carried warrants. Mr. Damon was taken to a hotel and
+a doctor summoned. It was as Mr. Halling had guessed. His friend
+had been ill, and so weak that he could not get out of bed. It was
+this that enabled the plotters to so easily keep him a prisoner.
+
+<P>
+By degrees Mr. Damon told his story. He had rashly allowed Peters
+to get control of most of his fortune, and, in a vain hope of
+getting back some of his losses, had, one night--the night he
+disappeared, in fact--agreed to meet Peters and some of his men to
+talk matters over. Of this Mr. Damon said nothing to his wife.
+
+<P>
+He went out that night to meet Peters in the garden, but the
+plotters had changed their plans. They boldly kidnapped their
+victim, chloroformed him and took him away in Tom's airship, which
+Boylan and some of his tools daringly stole a short time
+previously. Later they returned it, as they had no use for it at
+the lonely house.
+
+<P>
+Mr. Damon was taken to the house, and there kept a prisoner. The
+men hoped to prevail on the fears of his wife to make her give up
+the valuable property. But we have seen how Tom foiled Peters.
+
+<P>
+The experience of Mr. Damon, coupled with rough treatment he
+received, and lack of good food, soon made him ill. He was so weak
+that he could not help himself, and with that he was kept under
+guard. So he had no chance to escape or send his wife or friends
+any word.
+
+<P>
+"But I'm all right now, Tom, thanks to you!" said he. "Bless my
+pocketbook, I don't care if my fortune is lost, as long as I'm
+alive and can get back to my wife."
+
+<P>
+"But I don't believe your fortune will be lost," said Tom. "I
+think I have the picture and other evidence that will save it,"
+and he told of his photo telephone, and of what it had
+accomplished.
+
+<P>
+"Bless my eyelashes!" cried Mr. Damon. "What a young man you are,
+Tom Swift!"
+
+<P>
+Tom smiled gladly. He knew now that his old friend was himself
+once more.
+
+<P>
+There is little left to tell. Chance had aided Tom in a most
+wonderful way--chance and the presence of Mr. Halling with his
+airship at just the right moment.
+
+<P>
+Tom made a diligent effort to find out who it was that had
+chloroformed him in the telephone booth that time, but learned
+nothing definite. Peters and Boylan were both examined as to this
+on their trials, but denied it, and the young inventor was forced
+to conclude that it must have been some of the unscrupulous men
+who had taken his father's patent some time before.
+
+<P>
+"They may have heard of your prosperity, and thought it a good
+chance to rob you," suggested Ned.
+
+<P>
+"Maybe," agreed Tom. "Well, we'll let it go at that. Only I hope
+they don't come again."
+
+<P>
+Mr. Damon was soon home with his wife again, and Peters and Boylan
+were held in heavy bail. They had secreted most of Mr. Damon's
+wealth, falsely telling him it was lost, and they were forced to
+give back his fortune. The evidence against them was clear and
+conclusive. When Tom went into court with his phonograph record of
+the talk of Peters, even though the man's voice was hoarse from a
+cold when he talked, and when his picture was shown, in the
+telephone booth, the jury at once convicted him.
+
+<P>
+Boylan, when he learned of the missing button in Tom's possession,
+confessed that he and some of his men who were birdmen had taken
+Tom's airship. They wanted a means of getting Mr. Damon to the
+lonely house without being traced, and they accomplished it.
+
+<P>
+As Tom had surmised, Peters had become suspicious after his last
+talk with Mrs. Damon, and had fled. He disguised himself and went
+into hiding with the others at the lonely house. Then he learned
+that the authorities of another city. where he had swindled many,
+were on his trail, and he decided to decamp with his gang, taking
+Mr. Damon with them. For this purpose Tom's airship was taken the
+second time, and a wholesale escape, with Mr. Damon a prisoner,
+was planned.
+
+<P>
+But fate was against the plotters. Two of them did manage to get
+away, but they were not really wanted. The big fish were Peters
+and Boylan, and they were securely caught in the net of the law.
+Peters was greatly surprised when he learned of Tom's trap, and of
+the photo telephone. He had no idea he had been incriminating
+himself when he talked over the wire.
+
+<P>
+"Well, it's all over," remarked Ned to Tom, one day, when the
+disabled auto and the airship had been brought home and repaired.
+"The plotters are in prison for long terms, and Mr. Damon is
+found, together with his fortune. The photo telephone did it,
+Tom."
+
+<P>
+"Not all of it--but a good bit," admitted the young inventor, with
+a smile.
+
+<P>
+"What are you going to do next, Tom?"
+
+<P>
+"I hardly know. I think--"
+
+<P>
+Before Tom could finish, a voice was heard in the hall outside the
+library.
+
+<P>
+"Bless my overshoes! Where's Tom? I want to thank him again for
+what he did for me," and Mr. Damon, now fully recovered, came in.
+"Bless my suspender button, but it's good to be alive, Tom!" he
+cried.
+
+<P>
+"It certainly is," agreed Tom. "And the next time you go for a
+conference with such men as Peters, look out for airships."
+
+<P>
+"I will, Tom, I will!" exclaimed Mr. Damon. "Bless my watch chain,
+I will!"
+
+<P>
+And now, for a time, we will say good-bye to Tom Swift, leaving
+him to perfect his other inventions.

+
+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any eBook selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2002 as we release over 100 new text
+files per month: 1240 more eBooks in 2001 for a total of 4000+
+We are already on our way to trying for 2000 more eBooks in 2002
+If they reach just 1-2% of the world's population then the total
+will reach over half a trillion eBooks given away by year's end.
+
+The Goal of Project Gutenberg is to Give Away 1 Trillion eBooks!
+This is ten thousand titles each to one hundred million readers,
+which is only about 4% of the present number of computer users.
