+CHAPTER I
+
+THE DEPARTURE OF THE OVERLAND LIMITED
+
+
+The Overland Limited, aglow with lights, stood in the Dearborn
+Street station in Chicago waiting for eight o'clock and the last of
+its fortunate passengers. Near the entrance gates, through which
+perspiring men and women were hurrying, stood the rear cars of the
+train. Within these could be seen joyous passengers locating
+themselves and arranging bags and parcels.
+
+In fifteen minutes the long journey of Ned Napier and his chum Alan
+Hope to the far southwest was to begin.
+
+At the other end of the big shed, where the cars of the long train
+seemed to fade almost out of sight, four persons were anxiously
+awaiting the approach of the hour of departure. One of these, the
+conductor of the train, consulted his watch, as he had done several
+times already, holding it close within the glow of his green-shaded
+lantern.
+
+"It's getting pretty close to time, Major Honeywell," he said with
+some concern. "You're sure he'll be here?"
+
+The man addressed, who stood leaning lightly on a cane and whose
+soft dark hat and clothes indicated his military calling, showed
+similar concern, but replied confidently:
+
+"We have nearly fifteen minutes. Young Napier has a reputation for
+never failing. I'm sure he'll be here in time."
+
+"Here's the telegram," interrupted young Alan Hope, as he drew a
+yellow sheet from his pocket. "It is from Youngstown, Ohio, and
+says Ned's train is on time. He left Washington yesterday and if
+everything is all right he reached the Union Depot a half hour ago.
+He'll be here."
+
+"Well, you know we can't wait, much as I'd like to," replied the
+conductor. "You'd better have everything ready."
+
+"She's dat, sah," interrupted the fourth person of the group, a
+young negro, who, as he spoke, placed his hand on the side door of
+the car, and moved it on its easy running bearings.
+
+"You see, there isn't much time left," continued the sympathetic
+train official. "We're coupling up." And he nodded toward the
+gloom beyond the train shed out of which the big compound locomotive
+was already emerging. The military man with the cane became more
+apprehensive.
+
+"What shall we do if Ned fails to get here?" he said suddenly after
+peering down the long platform toward the busy end of the station.
+
+"Oh, we didn't go into this to fail," cheerily responded the youth
+by his side. "If we 'fall down' it won't be on a simple thing like
+this. He'll be here. It won't take us but three minutes to
+transfer the stuff when it gets here. Never fear. I'll just take
+another look in the car to make sure."
+
+As he did so the colored boy exclaimed:
+
+"It's all right. Here's de screws as he done tole us to git and
+here's de screw-driver outen de box as he done writ us to have ready
+and dar's de door all ready fur to fly open."
+
+To prove it the lad gave the wide door in the side of the car a
+shove, and as it ran back on its track a portion of the inside of
+the car was exposed. It was a peculiar car and worth description,
+for in it, next to the big engine and ahead of all the other cars of
+the almost endless train, Ned Napier, his friend Alan Hope, and
+their servant, Elmer Grissom, were to be the sole passengers on a
+most mysterious and, as it proved, most eventful journey. In
+railroad parlance the car was what is known as a "club" car. Half
+of the interior was bare and unfinished, like the compartment in
+which, on special and limited trains, baggage is carried. This part
+of the car, now exposed to view, was dimly lighted with one
+incandescent bulb. In the half-light it could be seen that the
+space was almost wholly filled with tanks, boxes, casks, crates and
+bundles, all systematically braced to prevent jarring or smashing.
+It was plainly not the luggage of ordinary travelers. Except for a
+narrow passageway in the center of the car and a space about five
+square next the open door, every inch, to the very ventilators of
+the car, was crowded with bound or crated, numbered and tagged
+packages. In the open space next the door Alan Hope now appeared.
+
+"Coming yet?" he asked with apparent confidence as he peered
+outside.
+
+The colored boy Elmer shook his head.
+
+Just then the conductor returned and again his watch.
+
+"Eight minutes," he said; "time's getting along and I've got to go
+back and see about my train. I don't want to make you nervous, but
+do you want us to take this car if fails to get here with the
+stuff?"
+
+"I suppose there's no need," replied the military man, beginning to
+show irritation. "But there's eight minutes yet."
+
+"I know," replied the conductor, "but after we are coupled up and it
+is time to leave we can't stop to cut this car out. We've got to
+have five minutes for that. At five minutes of eight you'll have to
+decide whether it is go or stay. I'm sorry--but you'll have to
+decide in a minute or two."
+
+"Decide it now," interrupted Alan from the open car door. "We're
+going and he'll be here."
+
+The Major appeared to be in doubt as to the wisdom of this, but
+before he could say anything Alan continued:
+
+"Couple up whenever you want to, Mr. Conductor, we'll be ready," and
+he sprang out of the car, his face set with determination.
+
+By that time the throbbing engine had silently moved up next the car
+and two grimy depot men with smoky torches had swung off the
+footboard to make the connections.
+
+"Got to know," repeated the sympathetic conductor. "Only five
+minutes." He looked at the Major for the final word.
+
+The latter peered down the long almost vacant platform. There was
+no one in sight but the late arrivals being helped aboard the cars
+in the far end of the station. Then he gave another look of appeal
+at his own watch as if in doubt what to say. To send a special car
+half way across the continent was no inexpensive project. And to
+send it without the person or the precious material that it was
+intended seemed not only a waste of money but foolish. Although the
+anxious man had both confidence and nerve it could be seen that he
+was in a quandary.
+
+"Five minutes," exclaimed the railway official. "Does she go or
+stay?"
+
+Before the man could answer, Alan faced him and with a hand on the
+Major's arm exclaimed:
+
+"Ned will be here, he can't fail; tell him we're going."
+
+The Major smiled. "That's it," he exclaimed suddenly. "Take her
+along. It's up to us to take care of ourselves."
+
+"Good," said the conductor, "I hope he'll make it."
+
+With a signal to couple on the engine he hurried away for a final
+inspection of his train.
+
+For a moment the three persons left behind stood in silence. There
+was a hiss of the engine as it pushed the connecting blocks together
+and then those waiting so anxiously could hear the jar of connecting
+valves as the brake hose were snapped. Confident as Alan was, it
+gave him a sinking feeling. Then, as the swish of tests sounded and
+the gnome-like figures of the depot men crawled from under the car,
+the Major looked again at his watch in despair.
+
+"Four minutes--"
+
+Before he could say more Alan caught sight of a movement among those
+gathered around the last car at the far end of the depot.
+
+"There he is!" he shouted and darted forward.
+
+"He sho'ly is," exclaimed Elmer, his white teeth showing, "and Yar's
+de screw driver and yar's de screws all ready."
+
+A slowly moving truck had carefully turned the end of the waiting
+train and, drawn by two baggage-room employees, was making its way
+along the platform. By its side walked a boy--a lad of about
+seventeen. One of his hands rested on the truck and his eyes were
+carefully fixed on the load it bore. This was a black, iron-bound
+case about four feet long, three feet deep and perhaps a yard in
+height. On each side in red letters were the words:
+
+"Explosive; no fire." Beneath this ominous legend were two large
+iron handles.
+
+When the men drawing the truck quickened their pace the boy spoke to
+them sharply and they fell again into a steady walk. For the
+curious onlookers through whom the strange little caravan passed the
+lad by the side of the truck seemed to have no concern. A traveling
+cap was pushed back from his young face and his keen and alert eyes
+and the tone of his voice indicated a quality that goes with those
+born to command.
+
+"Hello, Ned," came a ringing greeting from Alan as he ran forward.
+"They were afraid you wouldn't get here. But I knew you would.
+It's only a minute or two. Hurry."
+
+"Four," said the new arrival cheerfully and confidently.
+
+He gave his left hand to Alan and a better welcome in a cheery word
+of greeting, but his right hand did not leave the truck. Nor did
+his eyes leave it except for a moment.
+
+"And the Major?" asked the new arrival as the truck rumbled on.
+
+"Waiting to bid us good-bye."
+
+"Everything aboard and shipshape?"
+
+"Everything but this," and Alan glanced at the black case on the
+truck.
+
+"I've carried it a thousand miles like a baby," laughed Ned. "Rode
+with it all the way in the express car."
+
+"Then you didn't sleep last night?"
+
+Ned laughed. "It was too interesting," he answered, "and I can
+sleep to-night. But I'm glad it's here with no one killed and not a
+drop spilled."
+
+Advancing leaning heavily on his cane, the military man had hurried
+forward, his face radiant.
+
+"Welcome, my boy, and congratulations. But for goodness' sake
+hurry," he began hastily.
+
+Ned smiled again. "I think we had better not hurry this," and he
+pointed to the truck load. "That's the reason I'm late. I walked
+the horses from the Union Depot. You see we can't afford to spill
+our supplies. It was too hard to make and cost too much."
+
+In another moment the truck was abreast of the open car door.
+
+"Back her up," exclaimed Ned giving a hand himself to the tongue of
+the truck. Then, as the top of the truck came up flush with the car
+door and floor he sprang lightly on the truck and motioned the men
+to do likewise. For a moment they hesitated, but being reassured,
+Ned and Alan and the truck men lined up on either side of the big
+case. Slowly and carefully, with a brawny truck man on each side to
+help the less stoutly muscled lads, the case slid forward and with a
+"yeo-ho" or two from Ned it was soon in the car. Without a pause it
+was pushed at once into a space outlined on the floor.
+
+"And about two minutes to spare,"' cried the Major from the platform
+jubilantly and thankfully.
+
+"Not quite," laughed Ned, "but it'll be a half a minute and that's
+as good as an hour. The screws, Elmer."
+
+The colored boy, who had been busy keeping out of the way, sprang
+forward to perform his part of the apparently ticklish job. It was
+then seen that each bottom corner of the mysterious box had an iron
+flange. In the center of' each of these was a small hole.
+
+"Major," called out Ned as the truck men climbed out of the car,
+"these men were very obliging and careful."
+
+The Major understood him, and as he began searching his pockets for
+a bill Ned quickly inserted four screws in the waiting holes and
+with a few sharp turns of the screw driver made the case hard and
+fast to the floor of the car. Almost as quickly he threw the door
+into place and bolted it, and then with Alan hurried out for a last
+word to the friend who was so much interested in his success.
+
+"Was I right?" he exclaimed. "Half a minute?"
+
+"To the dot," enthusiastically answered the Major. "Now, boys,
+good-bye. Everything in that car is exactly as you planned and
+asked. From now on it is subject to your orders alone. What mine
+are you know. God bless you both and good luck to you!"
+
+As the boys took his hand Ned handed him a letter. "I'm sorry I
+couldn't have seen my mother again, but please send her this. I
+wrote it to-day on the train."
+
+Far down the line of cars came the words, "all aboard," and Elmer,
+cap in hand, sprang onto the steps.
+
+"Good-bye," exclaimed Alan, "and thank you for the great chance
+you're giving us."
+
+"Good-bye," said Ned, "if we fail in our work it won't be your
+fault, Major."
+
+And then, as the train began to move, the boys stepped aboard, off
+at last, after six weeks preparation, in search of the lost Cibola
+and the treasure of the Turquoise Temple.
+
+
+
+
+CHAPTER II
+
+NED'S MEETING WITH MAJOR BALDWIN HONEYWELL
+
+
+Six weeks before Ned Napier and Alan Hope had set out on this trip
+Ned had been the surprised recipient of a mysterious note. In this
+message, written on the stationery of the Annex Hotel, he was urged
+to call on the writer the next morning at ten o'clock. With his
+mother's approval he had kept the engagement. The events which
+followed will explain how Ned came to take his momentous journey to
+the far southwest.
+
+Promptly on the hour Ned presented himself at the office desk. A
+clerk with a handful of letters gave him a half glance and turned
+away.
+
+"I say," began Ned in a voice that made the clerk turn quickly, "I
+want some information."
+
+The man stepped forward, leaned over the counter far enough to get a
+full view of his questioner, and answered:
+
+"All right, sonny. What can I do for you?"
+
+"You can tell me if Major Baldwin Honeywell is staying here."
+
+"Friend of Major Baldwin's?" asked the clerk, his smile broadening.
+
+"If Major Honeywell is stopping here I suppose he is paying well for
+his entertainment," replied Ned after a moment's pause.
+
+"Sure," answered the facetious clerk, "regular rates."
+
+"Perhaps that ought to include civil attention to those he has
+business with. I have an appointment with him at ten o'clock. I
+wish you would see at once that he knows I am here."
+
+The clerk's smile was not quite so broad now but he was still
+amused.
+
+"What name shall I give, son?" He was about to repeat the "sonny"
+that had grated a little on Ned's sense of the proprieties but he
+stopped short--and added: "Have you a card, Mr.--?"
+
+"I have no card and I don't call myself 'Mr.'," answered Ned, "but
+you can say that Ned Napier is here and will be glad to see Major
+Honeywell whenever it is convenient."
+
+At the mention of "Ned Napier" the clerk's airiness disappeared. A
+certain respect seemed to take its place. Then he leaned forward
+and said a good deal more politely: "You are not the Ned Napier?"
+
+"I never heard of any other one of that name," answered the boy.
+"But I think we are losing time. Please say I'm here."
+
+A moment later a page announced that Major Honeywell, in suite 8 A,
+desired Mr. Napier to be shown up at once. Reaching the apartment
+the page knocked and there was a quick "Come in."
+
+Hat in hand, and with all the manliness and dignity his seventeen
+years afforded, Ned stepped into the room. At a table a man had
+just risen as if from work on some papers. As the man turned to
+come forward and his eyes fell upon the lad he paused as if
+surprised. Ned Napier was neither large nor small for his age. But
+his circumstances had been such, financially, that his attire was
+plain and perhaps old fashioned--much of it the handiwork of his
+frugal and fond mother; and the absence of smart and up-to-date
+ideas in clothes and shoes made him look, perhaps, even younger than
+his years. Other lads of his acquaintance--those in his classes in
+high school--aped their elders. Ned's time and interests were too
+much given up to his boyish ambition to permit this.
+
+Ned saw a man of about sixty years, with snow-white moustache,
+dressed in blue. The man had every appearance of being both a
+soldier and an officer. His face was tanned as if by much exposure
+to the sun, but the line of white at the top of his forehead, where
+his hat gave protection, suggested that the color was both recent
+and transitory. Major Honeywell's hair, which was yet dark and only
+slightly streaked with gray, was too long to suggest present active
+service, as Ned at once concluded. His face, too, had something of
+the student in it, and this effect was increased by a pair of large
+gold spectacles with double lenses. The man's contracted eyes gave
+the youth the uncomfortable feeling of being microscopically
+examined, and Ned was for a moment ill at ease. The manner of the
+scrutiny was that of a scholar who had before him a strange new
+specimen. Ned, still with hat in hand, felt more like a dead bug
+than a very live boy. Then the white-mustached man smiled, took
+off his heavy-lensed glasses, and stepped forward with his hand
+extended.
+
+"I am Major Honeywell," he began in a low voice, "formerly of the
+regular army and later detailed on ethnological work for the
+Government. You are--"
+
+"Ned Napier," responded his youthful caller.
+
+"You must take no offense if I am a little surprised," exclaimed
+Major Honeywell; "I had supposed you would be older. Perhaps your
+surprise came first on receiving my note?"
+
+"It did," replied Ned; "I was surprised and so was my mother. But
+she thought I ought to come, although we could not imagine what you
+wanted."
+
+Major Honeywell smiled and motioned Ned to a chair with a
+graciousness that made the lad more comfortable. It had taken but a
+passing glance to reveal to the boy that he was in the presence of
+no ordinary man. The articles scattered about the room, which
+apparently were part of his host's traveling outfit, confirmed this.
+Of three leather cases or trunks in front of the mantel and within
+Ned's view, one was open. On the extended top of this, still partly
+covered with the folds of a light Indian blanket, were several flat
+and dull plates or dishes of Indian design, more or less broken and
+chipped. From the case came a pungent aromatic smell such as Ned
+had noticed in the "Early American" room of the museum. He was not
+quite sure what "ethno" meant, but he made a guess that it related
+to old Indian things, and this theory he confirmed to himself when
+he noticed on the table that Major Honeywell had just left another
+piece of pottery and by its side a large reading or magnifying
+glass.
+
+"A collector," thought Ned, more puzzled than ever.
+
+"I thank you for coming," said Major Honeywell finally. "It was
+good of you to do so. But I had supposed you were older--at least a
+young man," and he smiled again as if in some doubt.
+
+"Perhaps," replied Ned with just a shadow of resentment in his
+voice, "if you will tell me why you sent for me I can help you in
+making up your mind as to whether you were wrong in doing so. I'm
+seventeen."
+
+Major Honeywell arose, took off his glasses again and walked to
+where Ned was sitting.
+
+"I hope you'll not take offense, my boy. But my business with you
+is most important. It is possibly the most important thing that has
+ever come to me. Fate, or chance more properly, of course, seems to
+have brought us together. If what I have in mind and have partly
+hoped could be brought about, is brought about, you will have no
+reason to regret my sending for you. We must be sure of ourselves.
+So far we know almost nothing about each other. Since our
+acquaintance may mean a great deal to us let us be sure of
+ourselves. Therefore, you will pardon me if I ask you if you are
+the Ned Napier?"
+
+Ned laughed good-naturedly.
+
+"That's what the clerk down stairs asked me few moments ago--if I
+were the Ned Napier. Well, I never heard of any other Ned Napier.
+But boys don't carry credentials, you know, Major Honeywell. I'll
+take your word for it that you are Major Baldwin Honeywell, formerly
+of the United States Army, and now of the--what do you call
+it--ethno--?"
+
+"Ethnological survey," laughed the Major. "Then, since we know each
+other, I want to congratulate you, my young friend, on being one of
+the brightest, nerviest, and most promising young men of America.
+I've read about you and that's why I sent for you."
+
+Ned could only conclude one thing and it made him blush. "You mean
+my dirigible balloon experience last summer?" he asked with growing
+embarrassment.
+
+"I do," replied Major Honeywell with what Ned thought was wholly
+unnecessary warmth and enthusiasm, "and I want to shake the hand and
+congratulate the youngest, most daring and most promising balloon
+navigator in the world."
+
+
+
+
+CHAPTER III
+
+THE RELATION OF MIGUEL VASQUEZ
+
+
+It may be well to recount how such a young lad as Ned had become so
+famous.
+
+Ned's father had been a consulting engineer with a fondness for
+aeronautics. When Mr. Napier died, a year before Ned's meeting with
+the Major, it was discovered that he was making in his little shop a
+small dirigible balloon to be used at an amusement park. Mr.
+Napier's death was sudden. Manufacturer's bills for the balloon bag
+and engine came due and Ned, young as he was, knew that he must pay
+them. Putting on all the dignity that his sixteen years would
+permit he called on the manager of the amusement park.
+
+"I hear your father is dead," said the manager. "I suppose we have
+lost the twenty-five per cent we advanced on the air ship."
+
+"Why do you suppose that?"
+
+"Because he had complete charge of the work and we have no one to
+take his place."
+
+"I mean to do that myself," said Ned.
+
+The manager smiled and shook his head. "No doubt you would try--you
+look it--but we don't care to experiment."
+
+"But you want the air ship, don't you? You've advertised it."
+
+"Yes, it was ordered--through your father. Since he is dead and
+cannot contribute his services, our agreement is void."
+
+"Very well," replied Ned. "Good day."
+
+"Look here," interrupted the manager, "what do you mean to do?"
+
+"I'm going out to sell an air ship."
+
+"You mean our air ship?"
+
+"You said the contract is void."
+
+The manager laughed again, but not as jovially.
+
+"You ought to get on," he exclaimed.
+
+"I've got to get on, and I'm going to do it by being on the square."
+
+"I guess you're right. What's your proposition?"
+
+"Since you've thrown up the contract I'm going to sell the balloon
+at a profit. The price is now $3,000. And I want a contract as
+operator for six weeks at $100 per week."
+
+The manager stared at Ned and then exclaimed. "I'll do it. You are
+the very youngster we want."
+
+That was how Ned Napier came to finish the air ship his father had
+planned, and how it happened all that summer that the papers printed
+news stories and Sunday specials with pictures of his daring
+flights, and how Major Baldwin Honeywell and other happened to speak
+of him as the Ned Napier.
+
+To return to the scene of Ned's meeting with the Major--
+
+"My name is Ned Napier," the boy began as soon as his host's
+cordiality gave him a chance, "and I am the young man the newspapers
+wrote about."
+
+"I certainly made no mistake in sending for you," exclaimed the
+soldier. "But, before I say more I want you to realize that this
+is, to me, a most important matter."
+
+"You mean it is--"
+
+"A solemn secret. I want secure your services in a desperate and
+daring adventure that will mean a great deal to me--and a great deal
+to you."
+
+"Certainly," was the boy's response. "I give you my pledge on that."
+
+A look of relief came into the old soldier's face.
+
+"If I furnished you the money," went on Major Honeywell suddenly,
+"could you produce in a short time a practical and manageable
+balloon?"
+
+Before the boy could answer the old soldier continued: "I don't mean
+one of those affairs in which ascensions of an hour or so are made.
+I mean one in which you could travel for several days--perhaps a
+week?"
+
+"No," said Ned, "it can't be done. No one has yet remained in the
+air in a balloon over fifty-two hours."
+
+Major Honeywell said nothing, but Ned could see that what he had
+told the Major had dashed some budding hope.
+
+"That is," Ned hastened to explain, "you couldn't do it unless you
+periodically renewed your supply of hydrogen. I really believe,"
+continued Ned, "that I ought to know more about what you are
+planning to accomplish."
+
+Again the white-mustached man was silent a few moments, and then he
+told without reserve the great secret. He began with an account of
+himself. Until three years before he had been an officer in the
+United States cavalry, stationed in the southwest. Then the
+President had assigned him to ethnological work. His special work
+was in the ruins of the Sedentary Pueblos. While scaling a cliff in
+this work he fell and permanently injured his left knee.
+
+Resigning from the army, he traveled for a year and then went to
+visit an old friend, Senor Pedro Oje, whose immense sheep herds in
+Southwestern Colorado had made their owner a millionaire.
+
+While here, hearing of an ancient nearby pueblo, just south of the
+Mesa Verde, Major Honeywell and his friend drove to the settlement.
+To Major Honeywell's surprise he found an old friend in Totontenac,
+the chief. As the two white men were about to leave, old Totontenac
+presented to his soldier friend an ancient funeral urn.
+
+Major Honeywell was almost paralyzed with astonishment when he saw
+that the vessel was sealed and that it bore on its side, instead of
+the conventional Aztec design, this inscription in black: "Miguel
+Vasquez, 1545."
+
+"What was in it?" asked Ned quickly when the Major came to this part
+of his narrative.
+
+"That man was undoubtedly a soldier who marched out of Mexico in
+1539 with Friar Marcos, the great explorer," went on Major
+Honeywell, ignoring the question, "and when others gave up the
+search for the famed seven cities of Cibola and the wealth of the
+Aztecs that every Spaniard believed rivaled the treasure of the
+Incas, this man kept on. Either by accident or design Miguel
+Vasquez was left by the expedition and six years later he wrote on
+cowhide and concealed in that vase one of the most valuable historic
+records extant in America to-day--confirmation that there was a real
+basis for the tales that lured the Spaniards to this region in quest
+of treasure."
+
+Stepping to a trunk Major Honeywell took from a compartment a tin
+tube. From this he extracted a stiff sheet of parchment-like
+material.
+
+"It's writing, isn't it?" exclaimed Ned.
+
+"Yes, and Spanish. It is Miguel Vasquez's last will and testament,
+written over three hundred and fifty years ago. And here is a
+translation of it. You may read it yourself. That is my
+secret--and yours now!"
+
+And these are the words that turned the current of Ned Napier's
+life:
+
+"A relation of Miguel Vasquez soldier of Spain made in the year 1546
+concerning the hidden city of Tune Cha. Coming out of Saint Michael
+in the Province of Culican I journeyed with Captain Marco de Nica in
+1539. At Vacupa I departed from him and remained now six years
+among those of this land. Three years I dwelt in the town of Acuco
+and heard often of the city of Tune Cha wherein is to be found the
+Temple of Turquoise than which none more beautiful is to be found,
+not even in Castile itself. Such I have seen with my own eyes. It
+standeth within a palace of five hundred rooms or more wherein are
+to be found priestly vessels of gold and silver. And this same
+palace or City of Priests is compassed about by a massive wall. And
+in the center of the palace standeth the Temple, facing the sun
+which is the sacred place of al Quivera, Arche and Guyas. And the
+walls of this Temple are naught but precious Turquoise even to the
+height of forty feet or more, and the pillars thereof are of gold
+and silver alternate. Knowledge of this hidden and beautiful city
+hath not been reported unto Spain nor even unto Nueva Espana. From
+Acuco it lieth thirty day's travel west of north and as I estimate
+in 36 degrees latitude in the mountains of Tune Cha. From the Rio
+de Chuco it lieth west six days' travel. Nor may it be discovered
+but by those who have knowledge of it.
+ Miguel Vasquez"
+
+"What I had hoped to do," said Major Honeywell at last, "was to make
+the most perfect balloon ever built and discover through you this
+hidden temple of turquoise treasure. You say you cannot do it."
+
+Something he had never felt before shot through Ned's body. His
+face flushed and then grew pale under the spell that was on him.
+
+"Major Honeywell," he said suddenly, "I don't know of a balloon that
+can be made to fly for a week. But if it is necessary to have one
+to do what you wish I'll make it and I'll find Vasquez's Turquoise
+Temple."
+
+
+
+
+CHAPTER IV
+
+THE CONTRACT, AND LIQUID HYDROGEN
+
+
+"I knew you'd do it," exclaimed Major Honeywell, beaming. "Now
+we'll have my friend Senor Oje up and get right at the details."
+
+"One moment, Major Honeywell. It is easy to say what I just told
+you. But it means I've got to do something no one has ever done.
+I've got to take with me--in the balloon, of course--the material to
+replace the gas I lose."
+
+"Well, that's easy, isn't it? For you--" qualified the old soldier.
+
+"I guess you don't know much about ballooning," laughed Ned.
+
+"Will money enable you to do it?"
+
+"I hope so! Other experimenters have tried to carry materials to
+make gas. I'm going to take the gas itself in a glass jar."
+
+"In a glass jar!"
+
+"Precisely. Liquefied hydrogen gas."
+
+At that moment Senor Pedro Oje, who had been summoned by Major
+Honeywell, entered the room. An almost Indian complexion and cast
+of countenance indicated his Mexican origin. What had taken place
+was related to Senor Oje, and he left no doubt that he was
+thoroughly in sympathy with the project. He soon put matters on a
+business basis.
+
+"We are to share alike in what is found, I understand," he said.
+"Major Honeywell will have a third interest because the secret is
+his. This young man is to have a third because the risk is his.
+And I am to have a similar portion for furnishing the capital. And
+that brings us to the real starting point," the Mexican capitalist
+continued. "What is it to cost?"
+
+"Ten thousand dollars at least," answered Ned instantly.
+
+"Phew!" exclaimed Major Honeywell.
+
+Senor Oje, not unused to speculative investments, gave no sign of
+surprise.
+
+"How shall it be arranged?" was his only comment.
+
+"Put that amount to my personal credit in the First National
+Bank--if you care to trust me."
+
+"We are trusting you with more than that," replied Major Honeywell
+with earnestness.
+
+"It will take me six weeks to make my arrangements. In that time,
+as I need the money, I will draw on the account," said Ned.
+
+"Very good," said Senor Oje; "I will draw up the agreement."
+
+"Now," continued Ned, addressing Major Honeywell, "what is your
+interpretation of the message of the Spaniard?"
+
+"Of course Vasquez's words must be modernized. What he termed the
+Tune Cha Mountains begin in New Mexico and extend northwesterly into
+Arizona and Utah. In many places their plateaus rise eight thousand
+feet above the sea. Their thousands of peaks and canyons are fit
+rivals of the wonders of the Grand Canyon of the Colorado. Nowadays
+they are known by many names--the Sierra Chusca, the Lokaeboka, the
+Carrisco. 'Thirty days' travel west of north' is not very definite,
+but it certainly locates the palace in the far northwestern part of
+these mountains.
+
+"The Rio de Chuco can only mean the Chusco river. The only place in
+its winding course that is six days' journey from the mountains is
+where it joins the Amarilla. This is south and east of Wilson's
+Peak, which is our landmark."
+
+"Very good," exclaimed Ned, briskly. "Now, what is the nearest
+point in civilization?"
+
+"Clarkeville, Arizona."
+
+"Then that is my starting point. This is June twentieth. I shall
+be ready by the last day of July. Of course I shall need a special
+car."
+
+"Very well," responded the capitalist. "I see you know what you
+want."
+
+"Incidentally," exclaimed Ned, "I shall, of course, be permitted to
+carry my own assistants."
+
+"Assistants? Yes, of course," replied Major Honeywell, "but they
+must be persons of discretion."
+
+"My chum, Alan Hope, who will make the ascension with me, will be
+one, and a colored boy, Elmer Grissom, who has helped me prepare for
+all my flights, will be the other."
+
+There was no dissent.
+
+"When shall I make my report?" Ned added.
+
+Major Honeywell and his friend conferred a moment.
+
+"Will five weeks be enough time for your exploration?"
+
+"I think so; perhaps less."
+
+"Then we will meet you at the Coates House in Kansas City on the
+first day of August."
+
+Senor Oje arose and lit a fresh black cigar.
+
+"It will be well for you and Major Honeywell to talk over these
+things while I see my Chicago banker," said he. And with a
+good-natured "Adios, Senores," he left the apartment.
+
+"Now, about this liquid hydrogen?" began Major Honeywell at once.
+
+"Well," said Ned, "instead of ballast, I'm going to carry reserve
+hydrogen with me."
+
+"And is that so difficult?" asked the Major.
+
+"Impossible, if you try to carry material to make the gas," answered
+the boy.
+
+"And so you are going to carry it in liquid form?"
+
+"I'm going to try, although the making of liquid hydrogen is, so
+far, pretty much a theory. It has been made only under tremendous
+pressure and at minus 423 degrees Fahrenheit."
+
+The Major whistled.
+
+"That is so cold that ice is red hot comparatively," explained Ned.
+"This work must be done, in Washington."
+
+They discussed the balloon itself, and the car and the engine for
+propelling it; where these were to be made in the East, and how they
+were to be forwarded to Chicago as they were completed. Ned himself
+was to go East at once and remain there until the last thing was
+accomplished.
+
+Ned's chum, Alan Hope, had just taken employment for the school
+vacation in a large sporting goods store not far from the hotel. A
+few minutes later Ned walked leisurely into this store and sought
+out the fire-arms department, where Alan was on duty.
+
+"Hello, Ned," exclaimed Alan, "what do you think of this?" And with
+a smile he handed him an automatic pistol he was inspecting.
+
+Restraining himself, Ned looked it over carefully.
+
+"It holds ten cartridges and it's a beauty," declared Alan.
+
+Ned weighed it carefully in his hand. "What's it worth?" he asked
+with dignity.
+
+"Eighteen dollars."
+
+"I think we'll need three of them!"
+
+Alan laughed.
+
+"And there are a good many other things I think we shall need," went
+on Ned, soberly.
+
+"This hot weather is pretty bad on some people," laughed Alan.
+"But, by the way, who are 'we?"'
+
+"You and Elmer Grissom and I," answered Ned carelessly.
+
+"And where are we going?" continued Alan, who was not unused to
+Ned's joking.
+
+"On a little run in a private car down into New Mexico."
+
+Alan looked at him a moment and then determined to have the joke
+out.
+
+"Then what are we going to do?" he asked, still laughing.
+
+"Make a trip through an unexplored mountain region in the best
+dirigible balloon ever built."
+
+Alan wondered just where the joke came in. "And then?" he
+continued.
+
+"Discover enough hidden treasure of jewels and silver and gold to
+make us rich."
+
+"Shall I get you a cabbage leaf and some ice water?" asked Alan.
+
+"Get your father's consent that you can go; that'll be all,"
+announced Ned and then, breaking into a laugh, he relieved the
+perplexed Alan by explaining what had just taken place. In ten
+minutes Alan had secured permission to be off for the remainder of
+the day and the two boys hurried away for luncheon, to revel in
+dreams of their great opportunity.
+
+By night Mrs. Napier had consented, though with tears, to Ned's
+going, and later Alan's father reluctantly did the same. As Ned was
+to leave the next afternoon and had to see Major Honeywell and Senor
+Oje in the morning it was a busy evening that the two boys spent in
+Ned's workshop.
+
+At one o'clock in the morning Alan's work in Chicago was outlined
+and Ned's needs in the East were all listed.
+
+"And now," exclaimed the tired but exuberant Alan, "it is all
+arranged but the name. What are we to call the air ship?"
+
+"The 'Cibola,'" answered Ned without hesitation, "the dream of the
+Spanish invaders and our hope of success."
+
+
+
+
+CHAPTER V
+
+A DINNER PARTY ON THE PLACIDA
+
+
+The long, heavy, limited train on which the young air ship boys were
+at last embarked on their extraordinary mission pulled slowly out of
+the station.
+
+Ned made a quick survey of the Placida. Coming out of the baggage
+end he passed first into a drawing room. In this were two sections
+that opened up into four berths. Beyond the berths a passageway led
+to a private stateroom. When the boys reached the stateroom, Elmer
+was standing at the door with a happy smile on his face.
+
+"Fo' de captain," exclaimed the colored boy.
+
+"Where are you to bunk, Alan?" Ned asked, quickly.
+
+"Oh, the crew is in the main room."
+
+"Not much," exclaimed Ned. "We're partners in this enterprise. I
+don't have any better than the rest."
+
+And in another moment he had dropped his valise alongside Alan's
+berth.
+
+"We'll keep the little room for consultations," he said with a
+laugh, "when we don't want Elmer to hear us talking about the
+Indians."
+
+The colored lad grunted.
+
+"Can't scare me wif no Injun talk," he said. "I specs I ain't half
+so 'fraid o' Injuns as I is o' dat stuff in de black box."
+
+"And it's time to attend to the 'stuff,'" interrupted Ned.
+
+They returned to the baggage room.
+
+"Now," Ned began, "the door to this car must be kept locked except
+when the train crew are compelled to come through. We, in turn,
+must be careful about fire and lights. But, for fear of accident, I
+have taken some precautions."
+
+Alan and Elmer then saw that the top of the case was fitted with a
+lid the edges of which were bound with rubber. In the center of the
+covering was a short spout.
+
+"What's the use of an air and gas proof top with a hole in it?"
+asked Alan, inspecting it curiously.
+
+"Maybe dat's to let de air in and de lid's to keep de hydrogum from
+gettin' out," volunteered the colored boy.
+
+Ned was too busy to answer the one or to laugh at the other. He had
+unlocked the lid and thrown it back. About six inches beneath the
+top of the case stood eight iron boxes--two rows with four boxes in
+each. These boxes, six inches square, were each about three feet in
+height and in each could be seen the neck of a glass vessel.
+Securely packed in their iron jackets to prevent breaking, stood the
+glass receptacles, open-mouthed and apparently empty. But down
+below the shadowed rims were soft clouds of gaseous vapor, beneath
+which reposed the precious contents that had cost Ned over a
+thousand dollars--the liquid hydrogen.
+
+On top of the square iron buckets was coiled eight or ten feet of
+rubber hose. Taking it out Ned closed and locked the lid. He then
+screwed one end of the hose onto the open spout and, springing to
+the top of the case, passed the other end out of the open
+ventilator.
+
+"Now," Ned explained, "we are in less danger. Difficult as it is to
+condense hydrogen, it is more difficult to keep it in liquid form.
+It constantly seeks to return to gas. In a closed place it might
+make trouble."
+
+Elmer had already disappeared, with popping eyes and mumbles of
+protest. Alan proudly exhibited to his friend the results of his
+share of the work of preparation. Every crate, box, barrel and
+package was numbered and labeled and securely fastened in place.
+
+On one side of the car stood five large oak tanks, looking like the
+famous beer tuns of Germany.
+
+"I can make more hydrogen in those than you've got in your black
+box," Alan exclaimed jokingly.
+
+"I'll have a better look at them in the daylight," finally said Ned;
+"and now those easy chairs in the other car would feel pretty good."
+
+"Aren't sleepy, are you?" asked Alan, forgetting that his chum had
+not slept the night before.
+
+"No," said Ned, "only happy. But I'd be happier if I had had time
+to get a good hot supper."
+
+"All ready, sah, in de stateroom," announced Elmer's cheerful voice.
+
+Both boys turned--Ned in surprise.
+
+"Supper's all ready, sah!" continued the colored boy, "and waiting
+fo' you all."
+
+In the stateroom was a sight to arouse a sleepy boy and to delight a
+hungry one. In the middle of a small table was a bunch of pink
+roses. On either side, in a dish of cracked ice, was the half of a
+luscious cantaloupe. Silver knives, forks and spoons, sparkling
+glass-ware and snowy napkins at once revealed the resources of the
+Placida's pantry.
+
+"Well, I'll be jiggered!" exclaimed Ned.
+
+"Pretty nifty, eh?" laughed Alan.
+
+"Well, if this isn't the last straw!" exclaimed Ned as they seated
+themselves. "But I want to thank you both. I didn't know how
+hungry I really was--"
+
+He was about to plunge a spoon into the fragrant, cool melon when he
+saw a folded note by his plate. Opening it he read:
+
+"Dear Ned: Good luck and good voyage. The roses are from my own
+garden. Bring me a turquoise ring.
+ MARY HOPE."
+
+It was from Alan's sister.
+
+"Shall we do it, Alan?" he cried.
+
+"Shall we?" answered Alan wringing his chum's hand. "We'll do it
+or--"
+
+"Is you all ready for dis?" asked the young chef suddenly appearing
+with a smoking broiled steak. "It can't wait no longer."
+
+And it did not have to.
+
+An hour later the two happy boys sat on either side of the table in
+the drawing room of their car.
+
+"Are you getting nervous?" began Alan.
+
+"About what?" asked Ned.
+
+"Oh, about everything. The responsibility for this car and the
+setting up of your balloon, and the trip itself."
+
+"Are you?" exclaimed Ned.
+
+"My, no, I'm not. But then I'm not the captain. But I thought you
+might be."
+
+"Aren't we getting along all right?"
+
+"Perhaps too well," Alan answered.
+
+"Never talk that way," interrupted Ned decisively. "Everything is
+happening as it does because we planned it just that way. Things
+can't go too well. That is a foolish idea. The good fortune of
+careful preparation should only confirm your judgment."
+
+This was the sort of advice Alan had to take now and then from his
+friend; but it always did him good.
+
+"Then you don't believe in good luck?" rather sheepishly suggested
+Alan.
+
+"I believe in it, yes," replied Ned, "if it comes--and I never put
+it aside. But I never count on it."
+
+Sleep seemed to have fled from Ned's eyes. Although Alan suggested
+that it might be well to turn in early and be up early, Ned insisted
+on seeing Major Honeywell's chart of the country they were to
+explore, saying that he had another night on the journey in which he
+could sleep.
+
+The chart was really only a rough pencil sketch. The instructions
+were more in detail.
+
+"This country, now a portion of the reservation of the Navajo and
+Southern Ute Indians, is a wilderness," Major Honeywell wrote.
+"White men do not visit it because the Indians will not permit them.
+Mining prospectors who have tried to do so have been murdered."
+
+"Cheerful, isn't it?" interrupted Alan.
+
+"This jumble of mountains has no connection with our two great
+western mountain ranges. The towering plateaus, cut with yawning
+canyons, are plainly the result of some special volcanic action.
+This unknown region extends over a hundred miles northwest and
+southeast, and on all sides drops suddenly into the sandy deserts.
+At Clarkeville the desert begins at once. If you will start a
+little east of north and locate the Indian village of Toliatchi,
+twenty miles away, you will be on the Arroyo Chusco. Although the
+bed of this stream may be dry it can be traced northward sixty-five
+miles, where it unites with the Amarilla, eighty-five miles from
+Clarkeville. At the juncture of these water courses, if you face
+west, the roughest part of the Tunit Chas will confront you. At
+your right will be Wilson's Peak. That portion of the Tunit Chas to
+the southwest forms the Lu-ka-ch-ka mountains. To the northeast lie
+the Charriscos. Somewhere in these mountains lie the temple and the
+treasures we seek."
+
+
+
+
+CHAPTER VI
+
+BOB RUSSELL OF THE KANSAS CITY COMET
+
+
+When the Overland reached Kansas City at nine o'clock the next
+morning the air ship boys were just finishing an appetizing
+breakfast of fruit, omelet, pancakes and coffee. The Placida, their
+special car, came to a stop at the far end of the station train
+shed, and, covered with dust as it was, and almost hidden among
+hissing engines and baggage and express cars, there seemed little
+reason for it to attract attention. Of course it was not ignored by
+the railway officials. No sooner was the train at rest than the
+depot master and the division superintendent were knocking at the
+door. They had special orders concerning the car, and immediately
+wheels and brakes were being tested and ice and water were being
+taken aboard.
+
+The railway officials made a quick inspection of the car, asked if
+anything was needed, and were soon gone. A few minutes after they
+had left a young man suddenly appeared, dodging among the cars. He
+sprang on to the rear step of the Placida, but before he could enter
+the car, the door of which had been left open by the departing
+officials, the vigilant form of Elmer Grissom blocked his way.
+
+"Who's in charge here?" demanded the stranger. "I'm a reporter and
+want to see him in a hurry."
+
+The railway officials had been admitted through the baggage portion
+of the car, but Elmer knew that this way was not open to everyone.
+He understood the need of secrecy, and politely forcing the reporter
+out of the door on to the platform he led him to the front of the
+car.
+
+"If you'll give me yo' card," he then said with dignity, "I'll take
+it in, sah."
+
+As he was about to do so, Ned and Alan emerged from the car for a
+few mouthfuls of fresh air.
+
+"Hey!" exclaimed the impatient young man, "I'd like to see the man
+in charge of this car. It's important and I'm in a hurry. I'm a
+reporter for the Comet."
+
+The boys smiled.
+
+"We are in charge," answered Ned. "What can we do for you?"
+
+The reporter seemed taken somewhat aback at seeing two youngsters
+directing a special car. His bearing changed at once.
+
+"I've been sent to get a story about where you are going and what
+you are going to do," he said with a little more consideration;
+"that is, if you care to tell."
+
+Ned puckered up his lips and thought. He had met reporters before
+and he knew what a "story" meant.
+
+"I think we don't care to say," he replied in a moment. He did not
+even care to say it was a secret. Even that admission, he knew,
+would be a basis for something that might interfere with his plans.
+
+"Our correspondent in Chicago says you left there last evening with
+a carload of new and powerful explosives."
+
+"Was such a story printed this morning?" asked Ned, eyeing the
+reporter closely.
+
+"I think not," said the reporter, "but we are an afternoon paper,
+you know. We have a report that you are on your way to Mare Island,
+California, and that you have a carload of explosives for the navy."
+
+"Was such a story printed this morning?" repeated Ned, smiling
+again.
+
+"No, it wasn't. But it will be this afternoon," answered the young
+man impatiently.
+
+"If such a report had been known in Chicago last night," replied Ned
+sharply, "it would have been in every newspaper in that city and
+this city this morning. No correspondent sent you such a story.
+You are a poor guesser."
+
+The reporter was at least four years older than Ned and Alan.
+Therefore, he gave a little start of surprise. He had been trapped
+in a trick that he had often worked successfully on many an older
+person. For Bob Russell, easily the brightest and quickest-witted
+reporter in his city, thus to be turned down by two "kids" would
+never do. Without wasting time to deny Ned's charge, he tried a
+belligerent role.
+
+"Do you deny you have newly invented ammunition in that car?" he
+exclaimed brusquely.
+
+"I deny nothing and refuse to be put in the attitude of doing so,"
+calmly answered Ned. "Although it happens you are wrong again."
+
+The young man laughed and again changed his tactics.
+
+"Well, look here, boys, what's the use of getting mad about this?
+You're working on something, just as I'm working on a newspaper.
+You've got a good story somewhere about you and I'd like to have it.
+What's the matter with being good fellows and loosening up?"
+
+"Because it is purely a business matter in which the public would be
+too much concerned if it knew what we were doing."
+
+"Well, whatever it is, it's good--I know that," replied the young
+journalist, laughing, "and I'm sorry I'm not in it with you--special
+car--flowers--traveling like railroad presidents. I'm on. But,
+say, when this thing breaks I'd like to be in on the yarn. I was
+lying. I never heard of you before the train pulled in. But you
+know the railroad people are on. They told me you had a black case
+marked 'Explosive.' That's all I know. Say, couldn't you tell me
+this--are you going through to the coast?"
+
+Ned relented a little.
+
+"Perhaps," he said smiling, "we might go to the coast."
+
+"You might?" interrupted the reporter eagerly.
+
+"Or we might stop in the mountains."
+
+The reporter looked perplexed.
+
+"Then you've got something to do with mining?" interrupted the
+impulsive journalist, "and it isn't the navy yard. But you came
+from Washington! I know that, you see."
+
+"Yes," volunteered Ned, "but we might be from the Hydrographic
+Office."
+
+"Cloud breakers," quickly interrupted the reporter again. "How's
+that for a guess? Are you rain makers?"
+
+"What are they?" innocently asked Alan.
+
+The reporter saw he was wrong.
+
+"I give it up," he said shrugging his shoulders. "You are two wise
+lads."
+
+"Not wise," suggested Ned, "but attending strictly to our business."
+
+"Right you are," answered the reporter.
+
+"I've got to leave you to have a look through the train. Sorry I'm
+not in on this. Where ever you're going, it looks good to me. When
+you come back, don't forget me. Save the story for me, Bob Russell
+of the Comet."
+
+Handing his card to the boys with a cheery "So long!" he was gone.
+The boys felt a little relieved. They had done what they could to
+protect the interests of their patrons and themselves by keeping
+their mission a strict secret. So far as Ned knew, the only persons
+who had knowledge of what they were doing and where they were going
+were his mother and sister, Alan's family, and Major Honeywell and
+Senor Oje. Not even Elmer Grissom's parents knew where he was
+bound--it was sufficient for them to know that he was with Ned. Of
+course the railway people knew where the car was to stop. Beyond
+these it was necessary for no one else to know what was being
+done--not even the manufacturers who made the balloon, the engine and
+their precious gas. But what the young air navigators desired and
+what Bob Russell wanted were two different things.
+
+
+
+
+CHAPTER VII
+
+THE MAKING OF A NEWSPAPER STORY
+
+
+Let us see whether the young reporter was baffled by the reticence
+of the secretive boys.
+
+"Every one to his trade," murmured Bob Russell, as he hastened from
+Ned and Alan, "and now, me to mine."
+
+Bob was what was known on his paper as the "depot reporter." It was
+not the most important assignment, for usually his work consisted
+only in describing such notable personages as passed through the
+city and now and then in interviewing the more important of these.
+But this day he was confronted with a mystery and it was his
+business to solve it. He acted quickly.
+
+Hurrying after the depot master, with whom of course he was
+friendly, he persuaded that official to go at once to the conductor
+of the train and ascertain the names of the boys. This was a simple
+thing, done in that manner, for even the passengers in a special or
+private car must have regular tickets. The conductor at once
+revealed the identity of the three passengers. Although Bob knew
+the conductor, he realized that he stood a chance of being refused
+even thin information if he asked for it personally.
+
+While his friend the depot master was getting this information, Bob
+quickly, but apparently carelessly, approached the head brakeman who
+had helped bring the train from Chicago. It was Tom Smithers--also
+a friend of Bob's, who made a point of knowing every employee
+running into the station.
+
+"I see you've got the Placida with you?" began Bob indifferently.
+
+"Yep," answered Tom, "and loaded to the axles. All except
+passengers. She's running light on them. Two boys and a coon."
+
+"I just had a talk with them," remarked Bob, carelessly offering the
+brakeman a cigar. "Pretty dusty, eh?" After a moment's casual talk
+Bob returned to the subject.
+
+"I guess those kids must be next--running a car with locked doors."
+
+"Locked doors!" snorted Tom, putting his cigar away for a
+surreptitious smoke. "Not on your life. Not against me. You bet
+she was open whenever I rang."
+
+"But it might just as well have been locked," said Bob. "The place
+is so jammed full of stuff. I couldn't make out what it was, but
+there was a wad of it."
+
+The unsuspecting brakeman then gave Bob what he was hoping to get.
+
+"Well, I stopped and saw it," he confessed. "I roused up the coon
+after midnight to have a look at the ropes and when I came back I
+took my time. They got a case of powder or dynamite in there marked
+'Explosive.' I didn't bother that but the rest was plain. Half the
+boxes in the car were labeled 'balloon works' or 'motor works.'
+It's a balloon show--nothing else."
+
+"Where is the car going?"
+
+"They ain't consulted me," laughed Tom.
+
+A few moments later Bob was in the office of the division
+superintendent. When he left he knew that the Placida would be
+dropped on the only siding at the little town of Clarkeville in New
+Mexico. He had also looked over the best map in the offices and
+fixed in his mind the topography of the adjacent country.
+
+Before half past nine Bob had presented these scattered facts to his
+city editor.
+
+"It's a story, all right, Bob, and a good one. Go to it," said the
+editor. And Bob did the best he knew how--in a newspaper way. On
+the suggestion of the editor he telegraphed to the representative of
+the Comet in Chicago: "Who is Ned Napier?" In a little over an hour
+he had a hundred and fifty word telegram outlining Ned's aeronautic
+career and concluding: "Why? What do you know? Napier not here.
+Family won't talk."
+
+Then Bob began his story. It was, for a reporter of his experience,
+brilliant, with good deductions, good guesses and good ambiguous
+generalities. It seemed to tell more than it really did.
+
+At four o'clock that afternoon Ned and Alan were speeding over the
+green and fertile prairies of middle Kansas in blissful ignorance of
+what Bob Russell had done. Under striking headlines appeared the
+following story:
+
+"Ned Napier, the famous young aeronaut of Chicago, passed through
+the city this morning on his way to the southwest to execute the
+most daring and important balloon journey ever undertaken in this
+country. Accompanied by an assistant, Alan Hope, and on board a
+special car packed with $50,000 worth of apparatus he will proceed
+to Clarkeville, an insignificant town in New Mexico, from which
+place he will make his hazardous flight over the mountains lying to
+the north. The aerial journey may possibly extended over the Sierra
+Nevadas as far as the Pacific Coast.
+
+"The details of the expedition are not made public, as young Napier
+has been retained by the authorities at Washington and is operating
+under a strict pledge of secrecy. The knowledge that such an
+expedition is under way was made known for the first time to the
+representative of the Comet by Mr. Napier at the Union Station this
+morning. While slow to discuss the ultimate object of his trip Mr.
+Napier talked of his plans in a general way.
+
+"'I represent the Hydrographic Department,' he said to the reporter,
+'and the journey I am about to make may extend from Clarkeville as
+far as the Pacific. I hope it will accomplish what the department
+has planned, but you know that we who are in this profession are
+always prepared for failure. My assistant and I may easily have our
+lives crushed out on the rugged peaks of the mountain chain we are
+attempting to cross.'
+
+"Mr. Napier suggested that some might conclude that he had been sent
+out as a 'rain maker,' or 'cloud breaker' in an attempt to secure
+rain for the arid plains, but he laughed at this idea.
+
+"In the government's special car, carefully safeguarded, is carried
+a large can of a new and powerful explosive. In exhibiting this to
+the reporter Mr. Napier good-naturedly said:
+
+"'I am sorry I cannot tell the public the exact character of this
+new explosive. But the secret belongs to the government.'
+
+"When it was suggested that the explosive might be destined for
+certain elaborate experiments in the unpopulated wilderness of the
+region to which the expedition is now hastening on the Limited, Mr.
+Napier would only answer;
+
+"My lips are sealed. I can say no more. But I compliment the
+Comet in discovering what all the eastern papers have missed--that a
+stupendous thing is projected and that I have the honor, with my
+friend, Mr. Hope, to attempt it."
+
+Then followed an elaborate rewritten version of what had been
+telegraphed from Chicago concerning Ned. After this was a detailed
+account of the car, not omitting little Mary Hope's bouquet of faded
+roses, which in Bob's story became "a wealth of cut blossoms, the
+tribute of Mr. Napier's scientific friends."
+
+What Bob wrote was in type by twelve o'clock. Three hundred words
+of it were telegraphed to the Chicago evening newspapers. Sharp at
+six o'clock that evening the Chicago correspondent of the New York
+World sent advice to his paper that he had a story on the mystery of
+what Ned Napier was about to do for the government. Word came back
+at once to send on the story.
+
+At ten o'clock the telegraph editor of the World in New York took
+the account just received to the managing editor of the paper.
+
+There was a minute's consultation, a nod of the head, and at twelve
+o'clock that night Bob Russell was awakened to respond to a
+telephone call. It was his own managing editor who read him this
+telegram:
+
+Managing Editor, Comet, Kansas City
+
+Send man at once to follow Chicago balloon man and discover mission.
+Advance funds and draw on us. Will share story with you.
+
+Managing Editor,
+New York World.
+
+It is hardly necessary to say that Bob Russell was a passenger on
+the Limited leaving the next morning. He was just twenty-four hours
+behind in the race, but he meant, if he could, to execute his
+orders, and was already smiling delightedly in anticipation of what
+he knew would be a contest of wits.
+
+
+
+
+CHAPTER VIII
+
+THE HOSPITALITY OF NEW MEXICO
+
+
+Clarkeville was even smaller than the boys had imagined it. The
+little depot was far more pretentious than any other building in
+sight. Beyond this was a wide and exceedingly dusty street. On the
+far side of this unpaved roadway was a row of one- and two-story
+frame buildings. Here and there was a cheaper structure of little
+else but corrugated iron sheets, while to the left, where a similar
+street crossed the railroad at right angles, there was a one-story
+cement building proudly labeled "Bank." Both streets suddenly
+disappeared in a sandy, treeless plain.
+
+Wooden awnings in front of the buildings extended over the sidewalk.
+At the edge of these awnings were a few teams and many saddled
+horses, some of them hitched to posts, and others standing with their
+bridle reins dropped to the ground. Not many persons were in sight.
+The deep and cloudless blue sky was brilliant with the noonday sun
+while a hot breezeless haze hung over all.
+
+The Limited had made its usual daily pause and then to the surprise
+of the agent had run down beyond the water tank with one car,
+switched it back onto the one siding until it stood opposite the
+musty smelling freight shed, and, quickly coupling up again, had
+gone.
+
+Ned and Alan had alighted when the train stopped. Around them the
+boys could detect the first signs of the real West. At one end of
+the station a big-hatted Mexican squatted by a hot tamale can.
+Among others idling near were some high-heeled and sombrero-topped
+cow-boys, whose easy and loose clothing made Alan envious at once.
+Even the depot attendants, with their belts and loosely knotted
+neckerchiefs, seemed gayer and freer than their brother laborers
+back in the East.
+
+With coats off and collars loosened the two boys filled their lungs
+with the tonic air, for, in spite of the heat, a certain dryness
+seemed to give life and vigor to the atmosphere.
+
+"There it is, Alan," exclaimed Ned finally, pointing away to the
+north and the distant mountains, "beyond those peaks and somewhere
+under that sapphire sky is our land of promise. We'll be in it in a
+few days."
+
+The brilliant sky, the exhilarating air and the new life about them
+filled both boys with enthusiasm.
+
+"Whoopee!" almost shouted Alan finally, throwing out his arms as if
+to embrace his friend. "All we need is an Indian or two and I guess
+we'd be out West for sure."
+
+"You may not be so anxious to see them before we start back,"
+remarked Ned. "Anyway, I promise you enough of them in this
+country."
+
+With the departure of the train, the two boys became the center of
+some attention. Strangers were not plentiful in Clarkeville, and
+when the news spread that a special car was standing behind the
+freight shed on the far side of the tracks there was an instant rush
+of idlers in that direction. Ned and Alan returned with them and
+smiling good-naturedly right and left took stand at the forward car
+steps.
+
+It was about two o'clock in the afternoon, but so anxious had the
+boys become in the last stage of their journey that they had ordered
+Elmer to put off the noonday meal until they reached Clarkeville.
+The colored boy, troubled over the notion of a good dinner spoiling,
+was waiting on the car platform for it chance to get his "bosses,"
+as he delighted to call them, into the car.
+
+Before he could do so, and while the two chums were answering idle
+questions as to whether they were a "show," Ned's quick eye caught
+sight of a more important personage. A middle-aged man, not quite
+so western in appearance as the others, but plainly as much at home
+in the saddle, rode up with a clatter and sprang from his pony.
+
+Ned advanced quickly, spurred on by the new arrival's quick "Howdy,
+strangers!"
+
+"My name is Ned Napier," explained the lad, "and this is my friend,
+Alan Hope."
+
+The rider held out his hand.
+
+"I'm Curt Bradley, and I'm the mayor of this town," he replied by
+way of introduction.
+
+"Glad to meet you," answered Ned. "You've just saved me the trouble
+of looking you up, for that would have been my first business."
+
+"Not to be over cur'ous," laughed the Mayor as his eyes took in the
+big expensive car and then returned to the two boys, "might I
+inquire the nature o' yer business."
+
+Ned laughed.
+
+"Certainly," he answered, "but come aboard first. Elmer," he said
+to the waiting cook, waiter and porter, "another plate for Mr.
+Bradley."
+
+And in spite of the wholesome-looking but bronzed Mr. Bradley's
+protest that gentleman was soon sitting with the boys before what
+was perhaps the most elaborate meal he had ever eaten. His protest
+came from the fact that he had already had his dinner, but the fresh
+fruit and vegetables and spring chicken were temptations too strong
+for him.
+
+When Ned saw that their new acquaintance was at his ease and rapidly
+becoming satisfied he lost no time in coming to the point.
+
+"Our visit here, Mr. Bradley, is, in part, a secret. I hope you
+will accept my assurance, however, that it can in no way operate
+against or damage your town or its residents or the country round
+about. I want your assistance."
+
+"Ye can hev that," came the quick answer, "and if your lay is no
+one's business, why, it ain't none o' ours."
+
+"I'm glad to hear that," answered Ned. "But there may be some who
+will not be so considerate."
+
+"When I pass the word I guess they'll all think about like me,"
+interrupted the Clarkeville official. "Ye jest tell me what it is
+you want."
+
+"First I'll explain to you that in the other part of this car we
+have the material to make a dirigible balloon."
+
+"A what!" exclaimed the Mayor, his mouth full of chicken.
+
+"A balloon that you can guide through the air."
+
+Curt Bradley dropped his knife.
+
+"One o' them flyin' machines?"
+
+"Exactly."
+
+"And kin we all see it fly?"
+
+"Certainly," answered Ned, "if you will just see that no one
+interferes with us. I shall be glad in time to show you, I hope,
+the most perfect dirigible balloon ever put together and to explain
+just how it is to be operated. But in a few days, when it is ready,
+we are going to sail away on business that is our own. And when
+that time comes curiosity must stop. If anyone attempts to
+ascertain where we are going or what we mean to do I sound warning
+now that we will do all we can to prove to him that it is none of
+his business."
+
+The Mayor looked at them in surprise.
+
+"Why," he began, "I suppose ye must be on a mighty partic'lar job.
+Are you--?"
+
+"There!" interrupted Ned. "You see you are beginning to ask
+questions. Since we can't answer them we'd rather not hear them."
+
+"Right," exclaimed the Mayor. "Give me yer word it's all fair and
+square and that ye ain't violatin' no laws and I'll give ye my word
+they won't be no more questions asked."
+
+"I'm glad to do that," answered Ned, "we want certain accommodations
+for which we are willing to pay. But we want the confidence of
+Clarkeville that we are all right, even if we are a little young."
+
+"Clarkeville is yours," laughed the Mayor, getting up from the
+table, "and now what do ye want first?"
+
+In another hour the two boys, guided by Mayor Bradley, had examined
+the entire settlement. A little way down the railroad track they
+found a rather ramshackle building, mostly tin roof, and behind it a
+large plot of ground surrounded with a high corral or fence. The
+sign read "Buck's Corral." In the East it would have been called a
+livery stable. The air navigators engaged the place at five dollars
+a day for a week or more, and put a half dozen Mexican laborers at
+work removing the few horses and cleaning out the building and
+corral. The proprietor, who owned one of the few wagons in the
+town, they also hired as a drayman at $2.50 a day for himself and
+team.
+
+Work began at once. Through Mayor Bradley three reliable men were
+employed as watchmen, and these, in eight-hour shifts, undertook the
+duty of seeing that nothing in the corral was molested in the
+absence of Ned and Alan. Then the work of transporting material
+began, the first task being the removal of the five large generating
+tanks.
+
+Alan had been thoughtful enough to foresee the need of special
+clothing, and it was not long before he and Ned and even Elmer
+Grissom were enjoying the freedom of wide-brimmed hats, stout
+shirts, thick-soled shoes, and belts. Elmer's duty was the constant
+care of the Placida, which he only left on special permission. Ned
+and Alan were free to devote themselves wholly to the agreeable and
+long anticipated task of at last "getting ready."
+
+Help was easily hired and with Buck's wagon in service the
+wide-opened doors of the baggage car seemed to give out more boxes,
+crates and bundles than a full freight car. When strangers were on
+the car the colored boy stood like a sentinel over the black case
+which was made less conspicuous by being covered with a blanket.
+And his constant injunction "No smokin', sah," soon won him a
+sobriquet, Mexicans and cow-boys alike calling him "Smoky."
+
+Elmer was relieved from picket duty in time to prepare an extra
+supper to which Mayor Bradley, Buck, and Jack Jellup, the town
+marshal, were invited. It was extra work for "Smoky," who took his
+new name with a mild protest; but when he called the crew to the
+meal it was apparent that he harbored no resentment. Jack and Buck
+took their seats gingerly, but the boys soon made all at home.
+
+"There ain't agoin' to be no pay took fur this day's work," suddenly
+exclaimed Buck as he finished a generous portion of cold sliced ham
+and potato salad.
+
+The boys laughed in protest.
+
+"I ain't seen real food in ten years," continued Buck, "and what I
+said goes. This meal's worth a week's work to me."
+
+"All I got to say, young uns," interrupted Jack Jellup, the marshal,
+"is that this 'ere town is yours."
+
+Jack's idea of hospitality was an invitation to the boys to visit
+the town saloons as his guest, but Ned arid Alan laughed and thanked
+him, pleading weariness as a reason for declining. The final
+tribute of the three guests, however, before they left, was to push
+the Placida along with crowbars until it was free of the freight
+house and stood where the evening breeze could freely find its way
+through the windows. Then with hearty "buenos noches," ("Good
+night") and promises to see that every one was on hand early in the
+morning, they left.
+
+For some time Ned, Alan and Elmer sat in camp chairs on the car
+platform reveling in the glorious starlit night. From somewhere in
+the little town came the sound of low singing and a Spanish air
+played on the mandolin. It was all so different from the life the
+boys had known that it seemed like a dream. And when their real
+dreams did come it was of the not far distant Tunit Chas.
+
+
+
+
+CHAPTER IX
+
+"CALIFORNY KID" GETS A JOB
+
+
+Old Buck's horse-corral had blossomed over night into a modern
+balloon factory. And the proprietor, with his bronco team, and the
+superintending Ned and Alan made big gaps the next day in the
+precious freight of the Placida. By noon the five casks for
+generating hydrogen, the cooling and purifying box, and the lead
+pipe and other equipment, had been transferred to the old horse
+yard. Three tons of iron turnings, forwarded by freight in advance,
+were found in the keeping of the railroad agent. It took Buck six
+trips to move this, and that consumed the afternoon.
+
+A special trip was made by the wagon just after luncheon. This was
+to transport the tool chest--practically two chests, for it was a
+large one containing both wood and iron-working tools. With it rode
+the two boys, both in overalls and ready to begin the setting up and
+adjustment of the generating tanks.
+
+After their arrival at the corral, the rest of the afternoon, in
+spite of the heat, slipped quickly away. But by night a foundation
+had been leveled in a corner of the yard and the five barrel-like
+generators were firmly anchored and connected by lead pipes with the
+cooling and purifying box.
+
+"Looks purty much like a distillery," commented Buck, who had just
+made his last trip with the iron shavings, which were now piled
+close by the casks.
+
+"And is," laughed Ned, "in a way."
+
+But he volunteered no more. In fact the whole matter was a mystery
+to every one in the town, except Mayor Curt Bradley and Marshal Jack
+Jellup.
+
+In the morning the first work accomplished was the removal, one at a
+time, of ten casks of sulphuric acid, each weighing four hundred
+pounds. It was a delicate job and not unattended with danger in
+case of a cask breaking. The boys began to realize the need of help
+of a higher grade than that of the "greasers" who had been thus far
+their only assistants except Buck.
+
+Their usual good luck seemed to be with them, however, for just in
+the middle of the work of sliding a heavy carboy of acid from the
+wagon a stranger stepped from the group of onlookers, and without
+words gave a hand to the job.
+
+Alan was about to thank him hurriedly, when the stranger said:
+"Wot's the game, son? Wot's doin'?"
+
+Alan was at first inclined to resent this "tough" familiarity. Then
+he realized that the language of the man was in his natural manner
+of speaking, and he said:
+
+"Who are you and where are you from?"
+
+"Give you one guess," laughed the stranger. "No! Can't tell a
+'bo'? Well, just tramp. Wot's dew name? I lost me card case. Me
+nom de plumb is Kid, Californy Kid. And me address is--well wot's
+de name o' dis munificent metropolis?"
+
+"Clarkeville, New Mexico," answered Alan smiling.
+
+"Well, den me address is dat. Wot's de nex' inquiry?"
+
+The man was young. His clothing was worn and greasy, his shoes were
+patched, and those parts of his face and hands that could be seen
+between smears of coal dust were red from exposure and the sun.
+
+"How do you happen to be here?" continued Alan.
+
+"Well, cul--beg pardon, son--de fact is I lost me purse and de
+brakeman on de fast freight wouldn't take me check. I was dumped.
+And I can't get away exceptin' I walk."
+
+"Then you wouldn't care to work?"
+
+"Will dis beautiful city give me coin and chuck widout work?"
+
+"I'm afraid not," laughed Alan.
+
+"Den' it's work for yours truly," answered the tramp with a sort of
+cheery humor. "But, say, boss, ye couldn't stake me to a drink and
+some chuck afore I loosen up me muscles?"
+
+"Your pay will be two dollars a day," said Alan, "but no drinking
+goes. Here's a note that will get you something to eat." And
+writing a message to Elmer the tramp was soon hurrying to the car
+for a meal. A half hour later, with his sleeves rolled up, he
+returned, riding alongside Buck on the wagon.
+
+Ned had given the new hand little attention.
+
+Now he looked him over and asked:
+
+"What's your real name?"
+
+"Gus, boss; or, spellin' it out, Gustave Lippe. How's dat for a
+handle--Lippe?"
+
+Ned looked at the young man long and sharply.
+
+"One name, they say, is as good as another out here. But I didn't
+know tramps got this far west."
+
+"Sure," answered the tramp, "It's long jumps and hard ones. It's me
+last excursion dis way."
+
+"Well," said Ned slowly, "you can work for us as long as you are not
+too inquisitive."
+
+"Dat's me, boss. I'm de clam till me two dollars per will git me to
+de next whistle."
+
+"Then you'd better arrange to board with Buck."
+
+"Dat's me lay, boss, already booked. Now show me some work. Me
+trunk was checked t'roo and I ain't nuttin' on me mind but me job."
+
+"Well, you had better spend the rest of the afternoon in cleaning up
+a bit," suggested Ned. "Here's five dollars in advance. Report
+early in the morning."
+
+"Tank's, boss," said Gus, the tramp. But he took the bill slowly.
+
+"But, you can't spend it on beer and whisky and work for us," added
+Ned.
+
+Gus shifted uneasily.
+
+"You'd better have a bath and a shave. And if you need clothes and
+can get them here," continued Ned, "I'll advance more to-morrow--if
+you show up all right."
+
+"I kin work widdout a shave," the man said, "ain't der nuttin' doin'
+to-day?"
+
+Assured that to-morrow was when he was wanted the tramp slowly and
+apparently reluctantly turned and slouched away toward the stores.
+
+"What do you make of him, Ned?" asked Alan as the two toys resumed
+work.
+
+"Too slangy, I think," commented Ned.
+
+But the final stowing of the acid soon drove the tramp from the
+minds of the boys.
+
+When the young aeronauts finally closed the corral and returned to
+the car, the sun a great red ball, was just dropping behind the
+serrated mountains of the western horizon. On the car steps, Ned
+turned and pointed to the north. Far away the dusky gray of the
+plains deepened into darker and darker shadows that ended in a low
+black mass. But here and there from the black wall rose irregular
+spires, their tops pink-tipped by the red sun.
+
+"Yes," exclaimed Alan, "the Tunit Chas--our mountains."
+
+And even though the vigilant Elmer called from within, the boys
+stood and gazed in silence until the last glow had died away and the
+land of their hopes was lost under the stars.
+
+Important as was the work to be done in Buck's corral, there was
+another vital thing to be accomplished while this progressed. That
+was the creation of a base of supplies near the navigator's field of
+work. This was preferably to be at the junction of the Amarilla and
+Chusco rivers, and that point lay just eighty-five miles to the
+north. Between Clarkeville and that spot there were no roads and,
+at this time of the year, perhaps, no water. With the best wagon
+and team they might be able to get, this trip over the desert would
+require not less than five days.
+
+It was impossible for either of the boys to go on this important
+errand, as both were needed on the spot to set up the balloon. So
+it had long since been decided that Elmer was to have charge of this
+secondary expedition. And since it was Elmer who would have to
+conduct the expedition safely to its destination and establish a
+relief camp, the colored boy had been thoroughly coached in his
+coming task.
+
+"Kin I?" the boy had said more than once. "When de Cibola gits dar
+I'll be dar. And ain't no Indians nor rattlesnakes nor hot weather
+goin' to break up dat camp."
+
+And the camp meant gasoline, water, food and a stepping stone back
+to civilization, whether the expedition ended in failure or success.
+As the boys had already planned that Buck should furnish the wagon
+and horses and guide Elmer's caravan, they had asked him to call
+that evening to talk it over.
+
+"I'm ready to start, yes, right now," Elmer had said as he served
+the good supper over which he had been laboring, "but I does jes
+nach'elly hate to turn you young gemmen over to dese greaser cooks."
+
+The boys laughed. "You don't think we can keep this up all summer,
+do you?" exclaimed, Ned. "Even 'greaser' cooks are better than
+having nothing to eat. And up there," nodding toward the north,
+"there won't be any cooks."
+
+"Don't forget," interrupted Elmer, "camp--camp--well, my camp. When
+you get dar dar'll be a good meal waitin' you and when you git outen
+de mountains I'll still be dar waitin' wid eatin's."
+
+The boys laughed again.
+
+"Like as not," suggested Alan, "if you get all that truck up there.
+You'll certainly have enough. But don't you bother about the eating.
+You just watch the water and the gasoline."
+
+"Till de snow flies," exclaimed Elmer with emphasis.
+
+"Which, right there," dryly remarked Ned as he disposed of the last
+of a generous slice of melon, "is rather indefinite."
+
+When Buck, whose real name they had discovered to be William
+Bourke--easily corrupted into "Buck"--appeared, the boys had a delicate
+job before them. Inquiry had quickly shown them that Buck's twenty-five
+years on the old Santa Fe trail as guide and an active service in the
+army as scout easily made him the man to conduct Elmer to the north.
+
+To all their long explanations and reasons Buck listened in silence.
+When there seemed nothing more to be said, Buck smothered the still
+glowing end of a cigarette between his dark weather-beaten fingers
+and said slowly:
+
+"When do we start?"
+
+It was arranged that on the second morning Buck should be ready for
+a journey of uncertain length; that the general direction should be
+north; that the final destination should be revealed by Elmer on the
+second morning out.
+
+"Soldier-like," Buck had commented, "and that's the way I like it."
+
+Buck and an assistant were to take an outfit of two wagons, each
+drawn by four horses. In the lighter wagon six barrels of water
+were to be carried for use in case the usual "water holes" were dry.
+In case of an accident, the lighter wagon and horses were to be sent
+south by the second man and Elmer and Buck were to make a quick dash
+forward with what water and supplies could be carried on the other
+wagon.
+
+Old Buck made rather light of the matter.
+
+"Injuns ain't nothin' nowadays," he had explained, shrugging his
+shoulders, "ye jest want to keep yer bearin's and git used to
+drinkin' atmosphere and ye'r all right."
+
+The contract with Buck called for thirty dollars a day in money and
+food for himself and a helper. Both parties to the contract were
+satisfied and after Buck's fresh cigarette disappeared in the
+direction of the town the boys lost no time in turning in for a good
+night's rest.
+
+
+
+
+CHAPTER X
+
+AN ERROR IN CALCULATION
+
+
+While Buck was busy getting his wagons and horses and water casks
+ready the next morning the boys were not surprised to see Gus, the
+tramp, drive up just after breakfast with the moving team.
+
+"Have you had breakfast?" asked Alan by way of a greeting.
+
+"Have," retorted Gus, pulling up his team awkwardly. "It's me
+wrappin' meself around tortillas till I feel like a bag o' corn
+meal."
+
+"I can't see that you've spent any great amount of that five dollars
+on yourself," interrupted Ned, noticing the tramp's unshaven face
+and the still visible traces of coal smoke.
+
+"Well, boss, ye'r right. Dead right. But, ye see, de barber o' dis
+growin' city only works on Saturday and me friend Buck's bat' tub
+has a leak. Anyhow, de ladies hereabouts is scarce and few. Think
+wot a swell I'll be when Sunday comes."
+
+"Come in the car. We've plenty of water, and soap too," suggested
+Alan, smiling.
+
+'"Well, boss, don't tempt me. I'm working. I can't soldier away no
+time dudin' meself up on do bosses' time."
+
+"All right," replied Ned, laughing, "every one to his taste."
+
+There was plenty of work to be done, and in a few minutes all were
+at it. The chief task this day was the unloading of the materials
+yet on the car. That had to be done by night, except in the case of
+the boxes marked "Overland," all of which had been carefully and
+specially crated for wagon transportation. Of these there seemed a
+great many, and they were all put in one pile in the space made
+vacant by the removal of the gas generators. The hydrogen case,
+covered with a blanket, stood always under Elmer's watchful eye.
+This was to be removed last.
+
+As the boys meant to stay close by their valuable outfit, they
+planned to load Elmer's caravan early the next morning and to see it
+start on its trying and dangerous trip. Then they intended to
+remove the hydrogen cask to the corral and take up their own abode
+in the same place. The Placida--with no little regret--was to be
+surrendered to the railroad and returned to Chicago.
+
+For that reason this was a busy day. Load after load of crates,
+boxes, and bundles were carried to the big corral, the teams
+stirring up the dust of Clarkeville's main street on their way. It
+was heavy work, and required care. Smoky-faced Gus was earning his
+pay. So skilful and adroit was he in executing tasks assigned him
+that Ned commented on it to Alan.
+
+While the boys were at their noonday lunch Buck appeared to report
+progress. The big wagon was to come from a sheep ranch, ten miles
+to the south. A man had gone for it and would arrive with it that
+night. The wheels of the smaller wagon were being soaked in water
+and the axles had been greased.
+
+Ned could not resist asking:
+
+"How's your new boarder, Buck?"
+
+"Ain't seen much o' him. Purty poor feeder fur a tramp. Can't get
+a tortilla down him nohow."
+
+Ned looked at Alan significantly.
+
+"Hasn't any baggage, has he?" continued Ned.
+
+"Not a stitch. Lessen you allow fur a extra suit o' underclothes."
+
+"Under clothing?" exclaimed Ned. "Two suits?"
+
+"Yep. And fine, too. My old woman washed a suit to-day and she
+'lows as how it cost more than the rest o' his outfit."
+
+"Don't you think that funny?"
+
+"'What?" responded Alan sleepily.
+
+"Why, a tramp with two suits of fine underwear?"
+
+"Probably he stole them."
+
+"And probably he didn't. A real tramp might steal them, but he
+wouldn't wear them."
+
+"Well, what do you care," laughed Alan, "whether he's a tramp or not
+so long as he's useful?"
+
+Ned was silent a few moments.
+
+"Tramp or not, that fellow will bear watching."
+
+"All right," conceded Alan, "I guess we can do that."
+
+By night the barn and horse yard of the corral looked like a
+combination manufactory and hardware store. The seven sections of
+the skeleton-like car stretched across the old horse yard like a
+disjointed snake; crated aeroplane guides, and the propeller and the
+rudder leaned against the fence, looking like the frame work of a
+house; the more compact engine, motor, radiator and fan stood ready
+for unpacking under the shelter shed, while shafts, connections and
+boxes of small parts filled a large part of the empty stalls. The
+tins of gasoline for experimental flights and the first trip to
+Elmer's camp were in a far corner of the yard, and in the wagon shed
+stood the two immense special trunks containing the gas bag and the
+Italian hemp netting.
+
+The evening meal was not as cheery and chatty an affair as the
+preceding ones had been, although Elmer had done his best in honor
+of their farewell. And the boys insisted that at this last meal the
+waiter should be dispensed with, and Elmer was put at the head of
+the table.
+
+"Yo' make me feel as if I was a startin' fo' do norf pole,"
+exclaimed Elmer. "I don't see what's de use of so much fussin'."
+
+"Well, anyway," exclaimed Ned, holding up a glass of iced tea,
+"here's luck to you, Elmer."
+
+"And de same to you," answered Elmer. "And to all of us."
+
+Rising bell was to ring at four o'clock the next morning; so the
+boys all turned in at once after they had cleaned up the kitchen.
+
+It was about twelve o'clock when a sudden call sounded through the
+car.
+
+"Alan!".
+
+It was Ned, who, clad in pajamas, was shaking his chum. The latter,
+dazed for a moment, sprang upright, soundly whacking his head on the
+upper berth, in which Elmer was snoring loudly.
+
+"What is it?" he exclaimed, rolling out on the floor. "Who hit me?
+Indians?"
+
+"Not yet," laughed Ned, shaking his "pal" into wakefulness.
+"Listen!"
+
+He struck a match, lit a candle and sat down on the edge of the
+berth.
+
+"You're a bum calculator," he began, eyeing Alan.
+
+"I didn't calculate where that berth was," answered Alan ruefully,
+rubbing a lump on the top of his head.
+
+"And you didn't calculate where we are now," somewhat excitedly
+added Ned. "And I didn't think of it until just now."
+
+"Go on," interrupted the still sleepy Alan. "If it's a riddle I
+give it up."
+
+"I suppose you know what the air pressure is to a square inch,"
+answered Ned, like a school teacher rebuking a slow scholar.
+
+"Why, 14.7 pounds, of course."
+
+"Where?" exclaimed Ned again, sharply.
+
+"Where?" echoed Alan.
+
+"Why, at the sea level-that's where. Not out here. Do you know how
+high we are above sea level right here?"
+
+Alan began to see the point and a smile came over his face. He had
+no chance to answer:
+
+"We're a little short of seven thousand feet up in the air right
+here in Clarkeville," continued Ned in about the same tone of
+exultation he might have used had he found a gold mine. "Now,
+listen. How many cubic feet of gas does our balloon hold?"
+
+That question was easy. The boys knew that as well as the
+multiplication table.
+
+"Sixty-five thousand, four hundred and ninety-three feet."
+
+"And how much weight is it going to carry?"
+
+"Three thousand nine hundred and thirty-five and a half pounds."
+
+"Exactly," went on Ned. "That's the weight we are going to carry
+figured at sea level. Did it ever occur to you that our sixty-five
+hundred feet of hydrogen can lift more way up here seven thousand
+feet in the air, than it can at sea level? Did it ever occur to my
+special engineer and calculator that as the weight and pressure of
+the air grows less our hydrogen will lift just that much more
+weight.
+
+"By the great horn spoon!" exclaimed Alan. "Give me that candle."
+
+In another moment he was at the drawing room table with a pencil in
+his hand. It did not take him long to make his calculations.
+
+"Live and learn," he exclaimed finally. "I'm certainly all you said
+was a 'bum calculator.' Our altitude here is 6,875 feet, for I took
+it to-day just for practice. And we can carry in our balloon just
+exactly 693.6 pounds more than we figured."
+
+"I thought so," laughed Ned. "It came to me in a dream, I guess.
+But you don't need to feel badly. You say I'm the boss, yet I never
+thought of it. You see, the trouble is that all the balloon
+ascensions ordinarily are made from the large cities of America or
+Europe. Who ever thought of ascending a mountain to get a start?
+But since we have done so we must figure accordingly."
+
+"And what is the first thing you are going to add?" asked Alan.
+
+"First thing?" exclaimed Ned. "First and last and in the middle,
+gasoline. We may find water in the mountains and we might even find
+food, but we're not going to find gasoline. Now we'll do part of
+our work whether Elmer meets us or fails."
+
+The incident showed the essential difference between Ned's mind and
+Alan's. Alan was careful, precise, and adept in detail. Ned had
+the "dreams" and inspirations of an inventor.
+
+
+
+
+CHAPTER XI
+
+A DISGUISE PENETRATED
+
+
+The boys, in spite of their broken slumbers, all turned out promptly
+at four o'clock the next morning. They found this hour the
+pleasantest of the day in this hot and dry region. The late moon
+was just disappearing, and over the plains swept a breeze that
+hinted of snow on some mountain peak not far away. Not a sound
+broke the stillness but the occasional cry of a skulking coyote.
+
+"Hear it, Elmer," said Alan, as the boys got busy in the baggage
+car. "You want to look out for those fellows."
+
+"I ain't feared o' no cutes and I ain't feared of no Injun,"
+solemnly answered Elmer, "jist so dem rattlers gives me de go-by.
+Dat's all I ast."
+
+Buck's big wagon had arrived and was backed up to the car and now,
+by the light of a lantern hanging above the door, the work of
+loading began.
+
+With their improved gas bag the boys had figured on a record flight
+without renewing the gas supply. They had hoped to be able to stay
+at least seventy-two hours in the air. But during a large part of
+this time they expected to drift without the engines, for they could
+not carry enough gasoline to last for more than twenty-four hours of
+engine work. By their new calculations they had more than enough
+gasoline, and according to Ned it seemed probable that the decreased
+air pressure on the bag might extend the period of flight another
+twenty-four hours, or to four days.
+
+After that all would depend on the liquid hydrogen. The remarkable
+qualities of this unique product were to be tested for the first
+time in the history of ballooning. When the gas in the bag had
+diminished by leakage through the valves and elsewhere so that it
+was no longer sufficient to carry the car, the liquid hydrogen was
+to be turned into gas which was to take the place of that lost. Ned
+had left Washington with sixteen cubic feet of the liquid in eight
+delicate Dewar bulbs, or casks. He figured that one-quarter of it
+would be lost by evaporation, leaving twelve cubic feet. This seems
+a small supply until one understands that the hydrogen increases in
+volume 880 times as it returns into gas from the liquid form. The
+twelve cubic feet of liquid, therefore, would give them a little
+over ten thousand cubic feet of new gas. And this, with the loss of
+ballast and provisions in three or four days, Ned calculated, would
+give the balloon a new life of a day or so.
+
+Therefore, the secret plan was a direct journey to Elmer's camp, a
+flight of eighty-five miles, which would bring the Cibola near to
+the foot of the mountains of mystery. After this camp had been
+located and more gasoline taken aboard the boys were to head their
+craft toward the Tunit Chas mountains. What would follow they could
+not foresee. With good luck they might be able to hover birdlike
+over the peaks, canyons and plateaus for five days. With bad luck
+they might have to come down sooner or fall. Then, if the Cibola
+failed them, they would have to find their way to the treasure
+temple and the ruined palace on foot in a rugged wilderness,
+infested with unfriendly Indians and reptiles, or struggle back, in
+some manner, if they could, to Elmer's relief station, and thus to
+civilization.
+
+Should the worst happen and the balloon fail them, the boys might be
+lost in a desolate region that is even now uncharted by the
+government. The only resources they would have would be the Cibola
+equipment and their own ability to take care of themselves. In any
+event, the knowledge that Elmer and Buck were in camp ready to
+succor them meant a good deal. And that was why the loading of the
+overland outfit had so much interest for the boys.
+
+Of tins of provisions there were many: condensed foods--German
+erbswurst, or army rations of ground peas and meat; dried potatoes;
+eggs in powdered form; preserved and salt meats; hard tack; tea and
+coffee; flour; and evaporated fruits. The water was already
+arranged for and the wagon containing the casks was at Buck's adobe
+house.
+
+On the floor of the wagon, packed in bunch grass, were the precious
+gasoline casks. On top of all came the silk waterproof tent and the
+camp equipage. Stowed under the seat was the box containing spare
+flags, a heliograph, part of a wireless telephone outfit (the other
+part was to be carried in the balloon) and compass. Two magazine
+rifles and ammunition were included in the outfit, and Elmer donned
+for the first time in his life a belt and holster to carry one of
+the magazine revolvers that Ned had bought on the day when he first
+told Alan what he had undertaken to do.
+
+By the time this work was done it was day. Then came breakfast,
+which Elmer insisted on preparing. He even demanded that he be
+given time to make hot biscuits. These, with thick slices of
+broiled ham, the last of their oranges, and hot fragrant coffee
+constituted the last meal on the Placida.
+
+As the meal came to an end the clump, clump of horses' feet in the
+sand announced that Buck had arrived and that it was time for
+breaking the "special car" camp. Alan and Elmer hastened to clean
+up the little kitchen that had given the boys so many savory meals
+and to pack up the remaining provisions, and Ned jumped off the car
+to see Buck.
+
+To the lad's surprise he found Gus, the tramp, just as dirty and
+just as cheerful as ever, proudly mounted on one of the newly
+arrived horses. Buck noticed the surprise in Ned's face and
+explained:
+
+"The helper I thought I could get fell down on me. My boarder's
+goin' with us. I guess he'll do."
+
+"You understand you don't know where you're going," said Ned,
+approaching Gus as he rolled off his horse, "nor when you're coming
+back?"
+
+"I knows dat we ride and dat dere's chuck a-plenty," smiled Gus,
+"and whichever way it is," he added lowering his voice and
+chuckling, "can't be no worse dan Buck's place--fur me."
+
+"Do you want to go?"
+
+"Well, I ain't a settin' up nights a longin' to, but to oblige a
+friend, Mr. Buck, I allowed meself to be persuaded."
+
+"Well, we'll see," said Ned.
+
+Ned rather wanted to watch this young man. Something suggested that
+the tramp was too quick witted to be made a party to their plans.
+Ned didn't exactly know what harm the stranger could do them, but he
+decided to talk it over with Alan. While Buck was hitching up the
+horses Ned turned to go into the car.
+
+They were loading from the far side opposite the hydrogen cask and
+as Ned passed the corner of the car he almost ran into the station
+agent. The agent, who was also the telegraph operator, had a
+telegram for Ned, which the boy took eagerly. Ned had sent a
+message to Major Honeywell, telling of their safe arrival, and did
+not doubt that this was some important afterthought of the Major's.
+The address ran: "Mr. Ned Napier, Private car Placida, Clarkeville,
+New Mexico." Tearing open the envelope Ned read:
+
+"Just learned Kansas City Comet has story mysterious trip for
+government starting Clarkeville. Real object not known. Look out
+not followed.
+
+"Baldwin Honeywell."
+
+With three jumps Ned was in the car and had pull Alan into the
+drawing room portion. The telegram was read again and the two boys
+looked at each other in astonishment.
+
+"How could they?" began Alan.
+
+"No matter how," answered Ned, almost out of breath. "They did and
+that's enough. Now I know!"
+
+"Know what?"
+
+Ned pushed his chum to the side of the car and pointed outside where
+Buck and his helper were at work.
+
+"Look at him," he exclaimed.
+
+"At Buck?"
+
+"No. At the tramp who won't wash his face, who has a gentleman's
+underclothes and who is so anxious to work for us!"
+
+"Well, I see him. But--"
+
+"Haven't you ever seen those sharp eyes before?"
+
+"You don't mean--?"
+
+"I do. If that isn't Bob Russell, the Comet reporter, I'm a goat."
+
+
+
+
+CHAPTER XII
+
+NED TO BOB RUSSELL'S RESCUE
+
+
+It was a time for quick and fast thinking, and Ned and Alan did it.
+Alan's instant suggestion that they denounce the disguised tramp was
+almost as quickly voted down.
+
+"So long as we didn't know who he was he had the advantage of us.
+Now that we know--" and neither of them now doubted the fact for an
+instant. "We have the advantage of him," argued Ned. "Let's turn
+that knowledge to profit. We can easily guess what he is trying to
+do. Major Honeywell's message says our real object is not known.
+This reporter has learned something, and I suspect he could have
+found quite a lot from the train crew. On that he has written a
+good enough story to attract attention. That shows he is no fool.
+And he wouldn't come out here unless he had been sent. Who would
+send him? Why, his paper, of course, to discover our real mission."
+
+"What can we do to head him off?" mused Alan.
+
+"There are two ways," suggested Ned, "and we've got to make one of
+them effective. I don't know how he has guessed but he must not
+have another guess. And he's seen a good deal."
+
+"We might have him arrested," suggested Alan.
+
+Ned thought awhile.
+
+"I'll tell you, Alan," he said finally. "The young men of the press
+to-day may write fanciful stories, and they may even 'fake' where it
+injures no one, but personally they won't lie. Let's call our tramp
+in here, confront him with his imposture and give him his choice of
+writing nothing or of being drummed out of town."
+
+"Who'll make him leave town?"
+
+"Marshal Jack Jellup wouldn't need two suggestions on that score.
+And more, he'd see that the order was obeyed. I don't like to do
+it, but I think we're justified. He's taking that chance."
+
+Again the thing was gone over, with arguments for and against, and
+then Elmer was hastily dispatched to find Jellup and bring him to
+the car.
+
+"And Buck will lose his helper," laughed Alan.
+
+"Better that than a second expedition on our heels," answered Ned
+
+"Gus!" he called, throwing open a window. "Come in here!"
+
+The tramp soon stood before them.
+
+"Geel Dis is a swell joint," were the tramp's first words as with
+apparent awkwardness he entered the car.
+
+Ned acted as spokesman.
+
+"You say you've promised Buck to go with him without knowing where
+you are going?"
+
+"Dat's about de cheese."
+
+"Well, we are willing. But I may as well tell you that this is a
+secret expedition. If you go you must promise that you will not
+tell anyone what you see or hear."
+
+The tramp's face suddenly took on a peculiar look, but it was gone
+as quickly.
+
+"I gives me woid. I won't open me trap to no one."
+
+"Meaning you won't say anything about it?" smiled Ned inquiringly.
+
+"Dat's it. Mum's de woid. I won't open me trap."
+
+"Nor write anything?"
+
+The furtive look came back, this time more pronounced.
+
+"Me to write! Wit wot? Me new typewriter?"
+
+"That isn't an answer. Do you promise, if we send you with Buck,
+that you'll neither tell nor write nor make known in any way what
+you learn about what we are doing?"
+
+"Say, look here, boss. Quit yer kiddin'. Me name is Lippe and
+mebbe I shoot it off a bit too frequent now and then, but you don't
+need to be afeered o' me peachin' to de udder'Bos.'"
+
+"I'm not afraid of that," continued Ned. "We don't care what you
+tell all the tramps this side of Kansas City. But we don't want you
+to print anything more about us in the Comet."
+
+Hardly a flush came on the tramp's face. There was a quick movement
+of the lips as if he were about to make protest and then he laughed
+outright.
+
+"Bob Russell," said Ned, also laughing, "would you like the use of
+our bath tub for a few moments?"
+
+"Would I!" laughed the young reporter rubbing his tinted and smoke
+begrimed hands together as if to wash them. "Well, I guess I would.
+My hands are up. What's next?"
+
+"Wash up and we'll see," exclaimed Ned.
+
+The young reporter was still laughing. "And if it isn't too much
+trouble," he asked, "would you mind if Buck took his check over to
+the depot and got the suit case that it calls for? Then we'll talk
+business."
+
+In less than twenty minutes the sun burnt, dirty Gus Lippe had been
+transformed into the dapper Bob Russell. When he reappeared in
+fresh linen, outing clothes and a natty straw hat, he was still
+laughing. Approaching the group in the drawing room, where Marshal
+Jack Jellup had now arrived, the young reporter took out his pocket
+book and a five dollar bill.
+
+"I'll pay that back first," he began; and then noticing one of his
+cards he politely handed it to the marshal. It read:
+
+ROBERT RUSSELL
+KANSAS CITY COMET
+
+"Ye'r a purty fresh kid," sneered Jellup.
+
+"At your service, Mr. Officer."
+
+Jellup had already received an explanation of the whole affair and
+was aching to exercise his authority.
+
+"Ye'r an impostor," he began, "and ef ye hadn't been caught, ye'd
+have taken money on false pretenses. I was onto ye."
+
+"Oh, now," interrupted Bob, "at two dollars Mex per day I'd have
+given good value."
+
+"Mebbe," retorted the marshal, "but these gentlemen hev come here on
+particular business and they came like gentlemen. The officials o'
+this city hev give their word that there shouldn't be no interferin'
+with their plans. And thet's what you're a-doin'. Now git!"
+
+Ned broke in:
+
+"One moment, Mr. Marshall"
+
+"Oh, that's all right, Mr. Napier," exclaimed the reporter, "he
+doesn't mean just that. He knows I don't have to leave here so long
+as I obey the law."
+
+"Ye don't, don't ye?" retorted the marshal. "Well, there ain't no
+back east law down here. Our law books mebbe got all burnt up. And
+mebbe I happen to be purty much o' the law myself. Ye'll git and
+git quick."
+
+Again Ned interfered.
+
+"I suppose if we ask you to permit Mr. Russell to stay here he can,"
+he asked.
+
+"Well, I reckon that would be so. Ef ye ask it I reckon I'll have
+to," he replied surlily.
+
+Ned and Alan held a brief consultation.
+
+"We have decided to ask the authorities to permit you to remain here
+on one condition."
+
+The intelligent face of Bob took on a quizzical air as he waited to
+hear the condition.
+
+"That is," went on Ned, "that you give us your word that you will
+not make known anything you have seen here, or of our plans so far
+as you may know them."
+
+Bob's answer was immediate.
+
+"I can't do that," he said, "I was sent here to do just that thing,
+and as quickly and as fully as I can. You ought to understand, and
+do, I think, that I have a duty to perform. I've taken the trouble
+to come all the way out here to get a story. I've got it and of
+course I'm going to use it. I should be false to my duty, to my
+employers and to myself if I promised not to do this."
+
+"But you don't know our story."
+
+"And I'm sorry. But I should have known it all if I had had a
+little better luck."
+
+"Then you won't promise?"
+
+"Decidedly not."
+
+The boys showed that they were as stubborn as he.
+
+"Then we'll see that you learn no more," Alan exclaimed angrily.
+
+Bob smiled. "You can't take away what I already know, and it will
+take a pretty long story to tell all I am going to guess from what I
+have seen."
+
+As he spoke his eyes were on Major Honeywell's chart of the Tunit
+Chas Mountains, which had carelessly been left lying on the table
+where it had been in use during breakfast in the last explanations
+to Elmer.
+
+Ned's face reddened in new anger. He did not resent what the young
+reporter was doing; he even realized that he might do the same thing
+himself; but he was chagrined to find himself caught in such a
+simple manner. That was a big piece of additional information for
+Russell to have, and Ned knew it. Hard as the thing was to do he
+would at least put the young man out of the way of further
+discoveries.
+
+"All right," he exclaimed, "we've tried to do the fair and decent
+thing, and if you want to be stubborn Marshal Jellup can do as he
+likes."
+
+"Git!"
+
+It was the marshal who spoke and he did so as if it were a pleasure.
+
+"I'll take the Limited west to Gallup at noon," said Russell, "if I
+can stop it and catch the eastbound train there to-night."
+
+"Then ye'll flag it along the road," shouted Jellup, "fur ye'll get
+out o' here on foot and in a hurry."
+
+"On foot?" exclaimed Russell in surprise.
+
+"That's what I said an' ye heerd me."
+
+Russell looked in appeal at the two boys.
+
+Ned was mad, and mad all over.
+
+"You are so quick to have your own way," he said, "you can't blame
+us."
+
+"All right," was the cheery response, "it'll lend a bit of local
+color to the story. Goodbye, boys. And good luck to you. I'll see
+you when you come back."
+
+"Remember," said Alan relenting a trifle, "we'll let you stay until
+we leave if you'll promise to write nothing."
+
+Bob laughed again.
+
+"What good would that do me? No experience means anything to me
+that I can't turn into copy. And as for walking--I'd walk from here
+to Kansas City or crawl before I'd lie down on my shop like that."
+
+"Come on, kid, get busy," exclaimed Jellup again. "An' when ye
+start, don't bother about lingerin', because I'll be hangin' around
+and I'm good with this at some distance."
+
+As he spoke he drew a Colt 44 and tapped it.
+
+"Never fear, Mr. Jellup," laughed Bob. "I suppose I can express my
+suit case to the next town?"
+
+"Ye can't do no business in this city, d'ye hear? Now, come on."
+
+"Say, partner," interrupted Bob with his usual good humor, "if you
+will let me take a snap of you I'll make you celebrated. 'Famous
+gun man' of New Mexico. It'll be great."
+
+In another moment the nettled marshal had Bob by the shoulder and
+was whirling him out of the car. On the steps he threw the suit
+case onto the sandy plain and then pushed the reporter roughly down
+the steps. Ned and Alan stood, with flushed faces, watching the
+reporter pick up his hat and suit case. Then young Russell made a
+remark they could not hear and the marshal's revolver flashed in the
+air. They could see the boy's face grow pale at last, but as he
+straightened up the two men disappeared around the freight house.
+
+Like a flash Ned was on the ground and after the marshal and his
+victim. Alan and Buck came running in the rear, for the alert Buck
+saw that something was in the air. It was early day and only a
+straggler or two was in sight at the depot. The sun, already
+mounting high, foretold a day of depressing heat. The steel lines
+of the railway stretched interminably eastward toward the first stop
+forty miles away.
+
+Bob Russell, pale but defiant, stood in the middle of the track, his
+heavy suit case in his hand.
+
+Suddenly there was the crack of a revolver and the dust flew about
+the young reporter's feet.
+
+"Jist as a sample!" roared the angered Jellup. "The next one'll be
+higher up." And his trembling finger pointed down the hot sandy
+track.
+
+There was nothing more to be done. The pale-faced but nervy
+reporter turned toward the east and started slowly down the track.
+
+Ned ran forward.
+
+"Russell!" he shouted, "Russell!"
+
+As the reporter paused and turned, hearing his name, there was a
+second report of the marshal's revolver and Russell's suit case flew
+from his hand, ripped and torn ragged by a forty-four bullet.
+
+The smoke of the explosion puffed upward and, where it had been, the
+marshal saw Ned Napier's automatic magazine revolver under his nose.
+
+The boy was white with indignation. The possible serious results
+that might come to him and his plans meant nothing in his anger at
+such a dastardly act.
+
+"It isn't a Colt," he said with dry lips, "but, if you make another
+move like that it's got ten shots and they come out all together."
+
+
+
+
+CHAPTER XIII
+
+QUICK JUSTICE IN THE WEST
+
+
+Jack Jellup, marshal and "bad man," was never more surprised in his
+life. But Jack was no fool, and something in Ned Napier's eyes made
+the westerner conclude instantly that he had unexpectedly and
+unquestionably "barked up the wrong tree." For a few moments the
+marshal and the young aeronaut stood facing each other and then
+Jellup sneered:
+
+"Do you reckon you'd better run this town?"
+
+"No, nor you," quietly answered Ned, "and if that's the way you are
+going to do it you can settle with me right now. I'm going to stand
+on my rights."
+
+He was conscious that Russell had hurried back and was behind him.
+Another second and there was a sharp click. Both Jellup and Ned
+turned to see the nervy young reporter with the torn suit case open
+on the ground at his feet. A snap shot camera was in his hand. His
+face was white, but there was a trace of his usual smile on it. Ned
+wanted to laugh too, but the situation was too serious.
+
+"I've got you both," said Bob, a little nervously, "and if it's a
+good one I've got a dandy--'shooting up the town or the bad man
+covered'--"
+
+Had it not been for Ned's lightning-like action these might have
+been Bob's last words. Jellup's pistol had flashed once more, but
+as it dew into position Ned's own weapon rose with it under Jellup's
+right hand and the marshal's shot passed over Bob's head. Before
+Jellup and Ned could recover themselves Bob's camera was on the
+ground and the reporter had his own revolver, which he had grabbed
+quickly from the suit case.
+
+In the center of this group now stood, unarmed, Alan Hope and old
+Buck. Almost at the same time a dozen men, attracted by the melee,
+had also intervened and had taken charge of the three excited
+combatants.
+
+Pushing the crowd right and left appeared the stalwart form of Mayor
+Curt Bradley, weaponless, but with the stem face of one who gives
+orders that cannot be ignored.
+
+"Put 'em up, every one of you," he exclaimed; "do ye hear? Put 'em
+up."
+
+"Ye'r both under arrest," shouted Jellup to Ned and Bob.
+
+There was a quick explanation and then Mayor Bradley, still very
+stem of face, ordered everybody across the street to his office
+above the drug store. Men seemed to spring out of the ground, and
+the room was instantly packed to suffocation. Marshal Jellup made a
+formal charge against the two boys of "resisting and interfering
+with an officer" and then each told his story. The decision was
+immediate. Mayor Bradley ordered that both boys be released and the
+court be instantly cleared.
+
+Jellup made his way noisily toward the door, his face white with
+rage. Apparently a number present were his friends and cronies, for
+the looks of sympathy that he got turned into open murmurs of
+dissent.
+
+Mayor Bradley was on his feet at once.
+
+"What's the matter?" he began incisively. "Is there some one here
+who wants to appeal from my decision?"
+
+The hubbub subsided but there wag no response.
+
+"The time to make any complaint about my decision is right now and
+to me," went on the tall Bradley, looking over those in the room.
+
+But no one apparently cared to take up Jellup's cause. When the
+spectators had gone the Mayor, who had sternly watched the slow exit
+of the last loiterer, turned to the boys.
+
+"I thank you, Mr. Bradley," exclaimed Ned earnestly.
+
+"And I want to thank both of you," quickly added Bob Russell, taking
+the hand of each. "I'm the cause of this and I'm sorry. I guess
+you saved my life twice," he added, wringing Ned's hand. "If it
+hadn't been for you the Comet certainly would never have heard from
+me again. I guess that, puts all my obligation up to you."
+
+"No," said Ned, "I can't let you say that. You have your own duty
+just as I have mine. We'll go over to the car and wait for the two
+o'clock Limited. Then you are at liberty to go and write your story
+and do its you like."
+
+"He don't have to leave," interrupted the Mayor; "this is a free
+town and it's going to be an orderly one."
+
+"And I'm not going to," broke in Bob. "You've got yourself in a
+muss over me and some of these soreheads may try to make you more
+trouble. If you'll let me, I'll stay to the end and if it comes to
+a mix-up I'm going to be right there with you."
+
+Mayor Bradley smiled and old Buck slapped the reporter on the back.
+
+"But how about the story you say you are going to write about us,"
+asked Alan.
+
+"There wouldn't have been any story if it hadn't been for Mr.
+Napier," replied Bob. "And there isn't going to be one until he
+tells me to write it. It's up to him."
+
+Ned was looking out of the window at the curious loungers standing
+in the street. He was thinking of the work yet to be done and of
+all the difficulties that the discomfited marshal might put in his
+way. It wasn't a "picnic proposition." He didn't fear for himself,
+but the thought of his expensive and delicate outfit and of how
+easily it might be irreparably injured was not reassuring.
+
+"Russell," he said finally, "I think we need you. If you care to
+stay with us we'll be glad to have you. It isn't because I don't
+want to be bluffed by Jellup, but because you are game. If you'll
+go with Buck and Elmer, I'll try to make it worth your while--some
+time--and you shall be the historian of this expedition--when the
+time comes to write its story."
+
+Am hour later the delayed overland expedition was on its way toward
+the desert. There had been a quick shopping expedition in the
+stores of Clarkeville and Bob Russell, in a new hat and boots and
+various other articles of clothing, most of them too large for him,
+sat proudly on the driver's seat of the second wagon. Around his
+waist was a new cartridge belt and holster carrying Ned's gift, a 44
+revolver--"for game or rattlesnakes," as the boys expressed it, but
+the weapon was not concealed when the little cavalcade traversed the
+main street of the town, and if Jellup was an onlooker Ned felt sure
+that the outwitted marshal would think twice before again molesting
+the expedition.
+
+"All set," laughed Bob, as the final farewells had been said, and he
+held up his camera, "now for the real thing."
+
+Ned and Alan were now alone. To tell the truth, the excitement of
+the morning had been rather trying for them, but if it left them a
+trifle nervous they soon forgot their apprehension in making the
+last of the transfer. There was now another reason for abandoning
+the car. With headquarters established in the corral they would be
+near the balloon and its equipment, and if Jellup should permit his
+ill will to develop into some overt act, they would be in a position
+more easily to protect themselves. For that reason a number of
+their "greaser" assistants were taken to the car before noon and the
+hydrogen cask was loaded on the small wagon and carefully freighted
+to the corral. Then followed the remainder of the provisions and
+the personal belongings of the boys. Early in the afternoon the
+Placida was closed and turned over to the railway agent.
+
+
+
+
+CHAPTER XIV
+
+BUILDING AN AIR SHIP
+
+
+When Ned announced to Alan that they would at once unpack and test
+the motor--"for we might as well stop if the engine isn't right," as
+he put it--all thoughts of the troubles of the early day vanished.
+And the motor certainly was a beauty. Though some expert had
+recommended the French motor, Ned had preferred to use one made in
+America, not only because he had been able to get it quicker but
+because he believed it as good as the foreign make.
+
+The engine had eight air-cooled cylinders, in two sets of four,
+placed at an angle of ninety degrees to each other. The crank case
+was of aluminum and the shaft of vanadium steel, hollow, and
+specially treated to insure toughness. All the studs or bolts were
+of the same steel. Complete, with balance wheel, it weighed two
+hundred pounds. The ignition was accomplished by six dry batteries
+and a single-wire vibrating coil. It was rated at fifty horsepower.
+
+So exactly had the preliminary work been done at the factory that in
+two hours the boys were able to have the engine bolted to the
+section of the car where it was to be used, and before evening the
+radiator tubes and pump of the cooling system were also in place.
+Temporary connections were set up and the sparking wires attached,
+and then the reservoir was filled with gasoline. A little jar as
+the wheel was turned, then a couple of sharp explosions, and the
+engine fell to its work as if it had been running for weeks.
+
+Ned shut it off after a moment's critical inspection.
+
+"Let her flicker!" pleaded Alan. "We've waited so long for a real
+one that I like to hear her buzz."
+
+"We'll let her buzz when we can use the buzz," laughed Ned.
+"Gasoline is gasoline, you know."
+
+Night did not stop the work of the eager lads. As soon as they had
+eaten a light meal, Ned and Alan, with a couple of lanterns and a
+half dozen of candles, began to adjust the sections of the car.
+These, seven in number, when joined, were 54.12 feet in length. The
+American spruce frame and the aluminum joints were all intact. This
+work finished the day.
+
+Blankets on the rough floor were good enough for the explorers that
+night. The luxury of the Placida's mattresses and fresh sheets was
+missed, as was Elmer's skill as a chef when it was time for
+breakfast the next morning. The boys were not so indifferent about
+this meal as they had been about that of the evening before. They
+had no stove, but they took the time to arrange a regular camp in a
+comer of the corral. A little fire was soon burning, at which they
+made coffee and toasted some bacon. This, with hardtack and some
+preserved fruit, they thought was enough, for they were determined
+not to disturb the carefully packed provisions that were to be
+carried in the balloon.
+
+"Have you had enough?" asked Ned as the last piece of scorched bacon
+disappeared.
+
+"Enough?" answered Alan. "A regular banquet!"
+
+Just then there was a loud thump on the closed door of the barn.
+
+"The hands are arriving," explained Ned, and he hastened to open the
+door.
+
+A few of the workmen were there, but the knocking had been done by a
+pleasant faced woman--apparently a Mexican. A black shawl covered
+her head and one arm. It was Mrs. Bourke, Buck's wife.
+
+"I thought," she said smiling, "hungry."
+
+Without further words she threw back the shawl and revealed a small
+tin pail. The appetizing odor made Ned's mouth water. In the
+bottom of the bucket were frijoles, or boiled and fried Mexican
+black beans cooked in pepper, and on top of these were a half dozen
+smoking hot tortillas or corn cakes.
+
+"Mrs. Buck," exclaimed Alan, "you have saved our lives!"
+
+All recollection of his recent banquet seemed to have disappeared,
+and so did Mrs. Bourke's bucket of beans and cakes, in double-quick
+order. The reward was a bright silver dollar for the thoughtful
+woman and a contract that she should come three times a day and
+prepare the boys' meals. It would have been easier to have gone to
+Buck's home, only a short distance away, but the boys were now
+determined to stay in the corral, or leave it only one at a time.
+However, they soon developed a taste for Mrs. Bourke's peculiar hot
+wholesome dishes and these, with what provisions they had on hand,
+were a fair substitute for Elmer's cooking.
+
+The frijoles having been disposed of, Ned at once went out, and was
+fortunate in finding a load of rough lumber and a sort of
+jack-carpenter. With the help of the boys a four foot-high series of
+"horses" or frames was set up in the center of the corral. This was
+for the car to rest on while it was being assembled. It was
+elevated so that the propeller and aeroplanes and rudder could all
+be tested after being set up. The propeller, 11.48 feet in length,
+revolved in bearings four feet above the bottom of the car.
+
+After noonday refreshment the middle section of the car, to which
+the engine was already attached, was carefully lifted into place
+with the aid of the workmen, and then the laborers were paid off and
+dismissed--all except the watchmen. From now on there was nothing
+that the boys could not do themselves, and they wanted to be
+undisturbed and alone. The putting together of the car was a treat
+of which they had long dreamed and they were happy in their work.
+
+The remaining sections were easily laid on 'the "horses" and then
+came the bolts and the bracing with piano wire. When brought
+together the fifty-four foot long skeleton was in shape much like a
+cigar. The main frame was six feet high, tapering to five feet at
+each end. In depth the dimensions were the same. The engine rested
+on the floor of the middle section and was accessible in all its
+parts from that compartment. An elevation of the floor in the
+forward part of this section made it possible for one to stand high
+enough to have an outlook in all directions through openings in a
+hooded elevation that projected above the top of the section.
+
+This hood was of a waterproof silk, coated with powdered aluminum,
+that metal being used because of its semi-incombustibility. This
+silk also covered the sides of the central compartment, making a
+wind-, rain- and waterproof cabin. The lookout windows on all four
+sides were covered with isinglass. The bottom of the framework of
+the car forward and aft of the engine compartment had a ladder-like
+flooring of spruce, inserted more for strengthening the car than for
+service. But on top of the car, reaching from end to end, was a
+continuous runway two feet wide which could be used in hurriedly
+visiting either propeller or rudder. This runway was protected by
+guide ropes of Italian hemp running through posts extended upward
+from the sides of the car. The top of the engine compartment was
+completely floored, making a platform 6 x 6.12 feet square. This
+was surrounded by a protecting network, and Alan named it the
+"bridge."
+
+A light rope-ladder extended into the engine cabin from an opening
+in the roof, making the top floor space or bridge and the upper
+runways quickly accessible. The gasoline reservoir, just forward of
+the engine, was connected with the bridge by a copper supply pipe.
+The extra supply of gasoline was to be carried on the bridge in the
+open air, and lashed to the netting instead of being stored in
+permanent reservoirs as is the usual practice. This was in order
+that the empty vessels might be thrown overboard when it was
+necessary to lighten the balloon.
+
+The other sections of the car were each 8 feet long and decreasing
+in height from 6 feet next the cabin to 5 feet at the end of the
+car. In the two sections just forward of the cabin and in the two
+just aft provision had been made for attaching the eight liquid
+hydrogen casks--four at each end. As this liquid was reconverted
+into gas the light sheet-iron casings might likewise be cast
+overboard to lighten the balloon. As needed, the liquid hydrogen
+jars, coated with mercury, were to be taken from their casings and
+carried to the bridge where the reconverter was located.
+
+Aft of the engine cabin was the store room for water and provisions.
+The grooves and rods for the counterweights and equilibrium adjuster
+ran in the middle of the upper footway and the propeller shaft
+rested on the bottom of the forward section of the car.
+
+At ten o'clock that evening all the work on the car was finished
+except the buckling on of the aluminum silk sides and the hanging of
+the propeller, the rudder and the aeroplane sides. It was as long
+and as hard a day's work as either of the boys had ever done. They
+were dead tired, but happy, and after a sousing wash-up they got
+into their pajamas and, throwing their blankets on the floor of the
+little office, were soon fast asleep.
+
+
+
+
+CHAPTER XV
+
+HOW JACK JELLUP LOST AN ARM
+
+
+In spite of his fatigue Ned did not sleep soundly. It had been
+threatening a thunder storm all evening and the increasing
+oppressiveness of the air made the young, aeronaut wakeful. The
+long whistle and jarring stop of the midnight local train finally
+fully aroused him. In the west the thunder was rumbling and great
+sheets of heat lightning promised a storm in a short time. After
+slipping out into the corral and seeing that the waterproof silk
+sides of the car were securely buttoned around the engine Ned
+returned and again tried to go to sleep.
+
+But his restlessness continued. In his early sleep he had had a
+vivid dream about the wagon expedition. In this he thought that
+Marshal Jack Jellup had followed Elmer, Bob and Buck and set fire to
+the wagons while his friends were asleep in camp. It was a relief
+to awaken and find that the flash of light was lightning and not, as
+he had imagined in his dream, an explosion of the gasoline carried
+in Buck's big wagon. He lay awake awhile regretting the quarrel
+with Jellup, and then he sank into a doze again.
+
+But his active brain would not rest. Again he fell into a dream.
+This time the picture was very real. The big balloon had been
+finished and launched. A thrill ran through him as he felt the
+monster craft poise and waver and then slowly rise above the corral.
+He could hear the cheers of those gathered about. But in the midst
+of them he heard the sudden crack of a revolver. Jack Jellup had
+put a bullet through the silken bulk of the bag. The cold
+perspiration broke out on Ned's forehead.
+
+The dream was so real that he thought he could hear the taunting
+voice of Jellup. In feverish excitement Ned sprang upright, to find
+a pair of strong arms clasped about him. He did not cry out. A
+wave of cold fear seemed to benumb his tongue and brain. He knew
+this was no dream.
+
+Forced onto his back, his face and eyes partly covered by the
+shoulders of his sudden captor, Ned's returning consciousness made
+him aware that there was a dim light in the office.
+
+"It's Jellup, Ned," exclaimed in a whisper a sudden voice which Ned
+instantly recognized as Alan's.
+
+"No more from you," exclaimed a rough voice in quick reply. "Here's
+the rope, Domingo."
+
+The man on top of Ned knew his business. Almost before the boy
+realized what was being done his hands and feet were caught in
+dexterous knots and he was helpless.
+
+"Now," continued the other voice, "let's have a few minutes' talk."
+
+Ned's assailant had arisen, and for the first time the boy could
+look about. In the center of the room, with a sputtering candle in
+his hand, stood the revengeful Jellup. His companion Ned at once
+remembered as one of the noisy court room spectators of the day
+before. Between the two, clad in his pajamas and similarly bound,
+was poor Alan.
+
+"Ye can stand or set, jist as ye like," began Jellup. "Me and me
+deputy hev made this little visit to ye fur a purpose. The citizens
+of this town is tired of yer carryin's on and they've just delegated
+me to ascertain what it all means. We got a purty good idee."
+
+"Well, what is your idea?" interrupted Ned, slowly regaining his
+composure and his natural defiance.
+
+"My idee is that ye don't need no flyin' machine anywhar except to
+git away quick and what we want to know is what air ye goin' to take
+with you when ye fly away?"
+
+"Nothing that doesn't belong to us," answered Ned, "if that is what
+you mean."
+
+"Ye ain't, eh? I suppose ye don't know that thar's enough cow money
+in our bank to be worth stealin'?"
+
+Both Ned and Alan looked at each other astounded.
+
+"You don't think we look like safe robbers, do you?" began Alan.
+
+"Ye look just slick enough fur that and more," retorted the marshal
+who had placed the candle on the table and roughly pulled Ned to his
+feet. "But I didn't come here to argy. Ye began by vilatin' the
+law and ye didn't come the way down here for no fun. Ef that ain't
+yer game, and we don't put it above ye, what's yer lay?"
+
+"There's only one answer," said Ned. "None of your business."
+
+The marshal shoved Ned nearer the table.
+
+"Mebbe ye want to apologize fur that little bluff of yers
+yesterday--"
+
+"No," said Ned, "but I'll accept yours."
+
+Jellup's right hand was on his revolver.
+
+"I ain't hyar to make no threats," he exclaimed, "and ye don't need
+to be afeered that I'm going to shoot ye. But I've got just one
+other little proposition. Ef ye don't cotton to that, why, thar
+ain't agoin' to be no Fourth o' July balloon ascension around hyar."
+
+Ned straightened up.
+
+"Your proposition can't be a fair one or you wouldn't come like a
+thief at this time of night--"
+
+Jellup's pistol flashed in the air but fell back again as the
+marshal's left hand shot upward and struck Ned full in the face.
+Even as the tears sprang into the bound boys eyes and pain and anger
+flushed his pallid face, the cowardly Jellup fell backward and
+stumbled to the floor. Alan, standing just behind the man, had shot
+his knees forward, striking Jellup's legs in the hollow of his
+knees, and, thrown off his balance, the westerner lay sprawling on
+the floor. Before the marshal's confederate could interfere, Alan,
+tightly as he was bound, had flung himself on top of Jellup and with
+all the power he could throw into the act had butted his head into
+the marshal's face.
+
+Am oath and a cry of pain indicated how true the stroke had been.
+Both Ned and the companion of Jellup sprang forward at the same time
+and the four fell in a silent distorted heap. But the encounter was
+unequal. In another moment both boys were lying side by side on the
+floor and their captors stood over them. Even in the half light of
+the little room both boys could see the blood-smeared cheek of the
+marshal.
+
+Jellup's hand was on Domingo's arm holding him back from further
+attack on the helpless boys and the marshal was restraining his
+anger as a snake withholds its venom until it strikes.
+
+"Purty good," sneered the marshal, "and the funny thing is ye hain't
+got a bullet through ye fur it. But my business ain't with dead
+ones. Onct more, air ye goin' to say what ye'r a plannin' to do?"
+
+"Since it doesn't concern you in the least," said Ned, slowly, "no."
+
+Jellup was silent a moment.
+
+"Fur kids ye seem to have plenty o' money. Ye'r purty free
+spenders. I'll give ye one more chance. Ef ye've got a thousand
+dollars handy fur a kind of a bond as it were I guess that'll sort
+o' protect us."
+
+"You mean for bribery?" exclaimed Alan.
+
+"No, just instead of stealing," angrily added Ned. "We haven't a
+thousand dollars and if we had you couldn't get a cent of it. And
+to save you some trouble I'll say that what we have is in your
+bank."
+
+Another half-uttered oath sounded on Jellup's lips.
+
+"In thet case," retorted the marshal, "we'll jest show you that we
+mean business. That's a lie about the bank. Produce or take the
+consequences."
+
+"Help yourself," replied Ned, "if you think we are lying."
+
+"I ain't no pickpocket," retorted Jellup, "this is official. I tell
+ye it's a bond and this is yer last chanct to make good."
+
+The boys remained silent.
+
+But Jellup's companion was already busy. Leaving the marshal to
+stand guard over the boys he made a quick search of their clothing.
+But Ned was not so used to money as to be careless in the handling
+of it and the six hundred dollars that he had in gold was in a belt
+carefully concealed in the top of the liquid hydrogen crate, which,
+for safety, had been stored in a corner of the room.
+
+When the silent Domingo threw down the working garments of the boys
+he took up the candle and began a tour of the room. The big black
+liquid hydrogen crate attracted his attention and he approached it.
+The red "Explosive--no fire" letters of warning apparently meant
+nothing to him, but Jellup halted him with a sharp warning, followed
+by a few words in Mexican. Domingo handed the candle to Jellup and
+the latter stepped toward the box.
+
+"That means what it says," exclaimed Ned quickly and sharply.
+
+The crate stood as it had been carried from Washington with the top
+on and the connecting hose extended upward through a hole made in
+the low roof in order that the slowly accumulating reconverted gas
+might escape in safety.
+
+"Mebbe," said Jellup, "mebbe yes and mebbe no. I guess they ain't
+nothin' agoin' to explode that ain't set afire."
+
+Ned noticed with satisfaction that the lid was properly locked.
+Jellup noticed it too. Without a word, he turned and easily found
+Ned's keys. Again he approached the crate, looking over the keys.
+
+"Jellup," exclaimed Ned in alarm, "there's gas in that box, and if
+you go near it with a light you'll blow us all up."
+
+"Gas, eh?" answered the eager Jellup. "Don't run no sich bluffs on
+me."
+
+"I warn you," cried Ned as the man approached the box, "it's taking
+your life in your hands."
+
+Something in the tone of Ned's voice must have alarmed Jellup, for
+he paused. Then he retreated a few steps and handed the almost
+burned out candle to the vigilant Domingo.
+
+"I allow I kin jest hev a look without no light to oblige you. I've
+been purty curious about this precious package ever since I see it.
+And ye'r a sight too anxious consarnin' my safety."
+
+What might really happen Ned did not exactly know. The gas
+generated from the liquid hydrogen was highly inflammable and
+explosive when confined. But the evaporation was exceedingly slow
+and the exhaust hose should easily carry the forming gas in safety
+to the air. But even a small accumulation might be in the partly
+depleted bulbs or the top of the crate and a fire would certainly
+ensue even if there was no violent explosion. And besides, just
+beneath the lid was their money--the cash Ned had secured for their
+further expenses and the return home.
+
+"We are anxious for all of us," explained Alan.
+
+"And mebbe anxious fur something else," sneered the marshal. "I
+reckon a peek in the dark ain't agoin' to hurt no one--an' it may
+help some."
+
+"Drop on your face, Alan," whispered Ned, "and lie flat."
+
+It was the only precaution they could take. Both felt that all
+their plans might end in a moment. But Ned could not resist
+watching--even though his face was close to the floor. He saw
+Jellup examine each key, guess the right one at once and then insert
+it in the lock. Yet, despite his assumed bravado, it was apparent
+that the man had considerable apprehension. For, before he turned
+the lock, he motioned to Domingo to retire further with the candle.
+
+Finally, as if summoning his courage, the avaricious marshal snapped
+the key, threw back the catches on each end of the crate and then
+slowly and gingerly and at arm's length began to lift the lid. With
+the top an inch ajar he paused, waited a moment or two, and then
+began sniffing as if searching for an odor.
+
+Ned saw him.
+
+"It doesn't smell," he explained quickly, "but it's there. Look
+out!"
+
+"Don't smell!" retorted Jellup. "Gas as don't smell? Well, that's
+agoin' some, I guess."
+
+Nevertheless, he had dropped the lid.
+
+But as quickly recovering himself he reached forward again and with
+a quick motion threw the top up and sprang back.
+
+To Ned's relief nothing happened. Either the light was too far away
+or the gas had all been removed by the hose. But this relief was
+quickly succeeded by another alarm. There had been no explosion,
+but their financial means were now at the mercy of two thieves, and
+he and his churn, bound and helpless, were powerless to protect
+either themselves or their funds. There was nothing to be done but
+to grin and bear it. For Ned's new leather money belt, containing
+six hundred dollars in gold was stretched out conspicuously and at
+full length on top of one of the two rows of glass bulbs in the
+case.
+
+"Lyin', as I thought," exclaimed Jellup. "Gimme' the light,
+Domingo." And the chuckle that followed almost instantly was
+indication enough that he had discovered the boys' small fortune.
+
+"Dangerous, eh!" he laughed. "Now, we'll see if the city gits its
+bond."
+
+Then he paused as if a thought had entered his head.
+
+"But, jest to keep the record clean, I reckon ye'd better give it to
+me yerself, young 'un. Jack Jellup ain't no burglar. Loosen him
+up, Domingo. And fur fear ye might need persuadin' jest take a peek
+at this," and he drew his revolver.
+
+When Ned had been liberated, Jellup pointed to the money belt.
+
+"Jest be good enough to hand me whatever's in that," he exclaimed,
+"without no hesitation. Then we'll have a little talk about what
+else is agoin' to happen."
+
+It was hard to surrender so easily but the risk of attacking two
+armed men single-handed was great. Ned walked slowly toward the
+crate.
+
+"Get busy," ordered Jellup; "we've got other business yit to talk
+of."
+
+Ned had a sudden impulse. The thing flashed on him and taking hold
+of the belt in the middle he lifted it until the two ends were just
+over an open-mouthed bulb of hydrogen, and then as if by accident
+dropped the belt into the jar. The clear, watery liquid splashed
+and the belt disappeared.
+
+"Water," shouted the eager Jellup, "Jist plain water." And as Ned
+sprang back the gold-fevered marshal sprang forward and plunged his
+hand into the liquid.
+
+He did not immediately know that his hand was in the depth of a
+liquid whose temperature was 423 degrees below zero. But the thin
+film of gas that instantly formed and protected his naked flesh
+dissipated in a moment and then one benumbing, paralyzing shock
+swept over Jack Jellup's body.
+
+With a cry wrung from him by pain such as few mortals have ever
+experienced and survived, the stricken man fell unconscious to the
+floor--his arm frozen as solid as crystallized steel.
+
+
+
+
+CHAPTER XVI
+
+READY TO "LET GO ALL"
+
+
+In the confusion that followed the sudden extinction of the candle,
+while Ned was freeing Alan and Jack Jellup was uttering heartrending
+groans, the marshal's confederate lost his nerve and made his
+escape. When a lantern had been procured, immediate attention was
+given to the stricken man.
+
+Ned hastened to secure a bucket of water. Wrapping the corner of a
+blanket about the handle of a tin dipper he ladled out a spoonful of
+the liquid hydrogen and, although the numbing chill ran through his
+fingers and up his arm, he managed to pour the hydrogen into the
+contents of the bucket.
+
+The pail of lukewarm water became almost instantly a cake of solid
+ice. As Ned dropped the tin dipper to the hard adobe floor it flew
+into a hundred pieces. The inconceivable cold had crystallized the
+metal until the slightest shock was sufficient to break it into
+pieces.
+
+At the sound of the crashing tin Ned instantly thought of the belt
+of gold yet in the hydrogen jar. But a human being was in pain, and
+he gave his first attention to the suffering marshal. He had made
+the ice to use in drawing the frost out of Jellup's frozen arm. In
+a few moments he had mashed a portion of the ice into small bits,
+and using a blanket to make a pack, he soon had Jellup's rigid arm
+encased in the fine ice. This he applied for the same reason that
+snow and ice water are applied to frozen ears and noses. But his
+treatment was of no avail.
+
+The rain was now falling steadily and it was dark, but Ned found
+that it was nearly day--a little after four o'clock. Jellup's
+suffering was so extreme that the boys had given him a hypodermic
+insertion of morphine, using their "snake-bite" outfit, and in a few
+minutes the man's ravings ceased and he quieted into a deep sleep.
+
+While awaiting this, attention was given the gold. Feeling free to
+approach the now open jars with a light it was seen that a portion
+of, the belt protruded above the liquid. A cord with a sailor slip
+knot was lowered over the extended bit of leather, drawn taut with a
+jerk and the belt was slowly lifted out. A folded blanket had been
+placed on the floor to receive it. As Ned expected, the leather
+crumbled and broke like glass as the belt fell on the soft blanket.
+
+"If you want change for a twenty-dollar gold piece just tap one of
+those with a stick." said Ned, laughing and pointing to the gold
+pieces scattered among the broken fragments of the belt.
+
+"Not I," exclaimed Alan, "not after what happened to the tin
+dipper."
+
+Leaving Alan to watch over the unconscious Jellup and the frozen
+gold, Ned dressed himself, and in spite of the rain hastened out in
+the just perceptible dawn to carry out a plan he and Alan had agreed
+upon. An hour later, with the assistance of Mayor Bradley, the
+marshal, now somewhat easier, was placed in a bed in his own home.
+Unless the silent Mexican told it no soul in all Clarkeville other
+than Mayor Bradley and the air ship boys knew why Jellup was absent
+from his haunts and his post of duty that day. Nor did many of them
+ever know, when Jellup reappeared on the streets after weeks of
+suffering, how he had been injured. They only knew that his right
+arm was gone and that he was no longer marshal.
+
+The rain ceased with the coming of the day.
+
+"If we don't get away pretty soon," suggested Alan, as Ned was
+getting into dry clothing preparatory to tackling another of Mrs.
+Buck's meals, "this thing will be getting on my nerves."
+
+"Well," answered Ned philosophically, "there is mighty little worth
+having in this world that isn't hard to get."
+
+If all went well that day the boys hoped to be ready to make their
+departure that night or the next morning. Therefore they went to
+work with a vim. Both felt more comfortable when, after finding
+that the gold coins had returned to their normal condition, they had
+again concealed them. The propeller, rudder and aeroplane guides
+were now put in place and tested.
+
+As the engine, with a speed of 1,400 revolutions but geared down to
+800, began to turn the shaft and the twelve-foot propeller began to
+revolve, Ned swung his hat in the air. Without a break the speed
+increased to 500, 600, and then 700 revolutions a minute.
+
+"Shut her off," exclaimed Alan joyously, as the white arms flew
+round and round and the air shot backwards on both sides of the long
+car. At 750 revolutions the car was rocking and lurching as if it
+would soar birdlike into the air. At 800 the powerful pulling
+propeller began to overcome the rigidity of the framework on which
+the car rested and as Alan caught and held the car, fearful that it
+was about to fly away under the propeller power alone, Ned shut off
+the engine.
+
+The next instant the two boys, with clasped hands, were doing an
+Indian war dance in their glee.
+
+It was not long until the rudder wires and the aeroplane shafts had
+been attached to their proper guide wheels in the lookout or pilot
+portion of the engine cabin. Then came the preparation of the
+balloon bag itself. Here again Ned showed what he had accomplished
+in the six weeks he had spent in the East.
+
+Clearing a space near the generating tanks, they placed the one
+hundred sand bags, weighing forty pounds each, in parallel rows.
+These sacks, with convenient loops on each for attaching the rigging
+of the bag as it was being filled, had already been prepared by the
+"greaser" laborers, but the placing of the two tons of dead weight
+was not a joke, and the boys regretted that they had not kept a few
+men around. But by noon this was done, and then the great
+waterproof fiber trunk containing the silk bag was rolled out
+between the retaining bags. The boys could not carry it, as the
+balloon itself weighed seven hundred and twenty pounds, but they
+improvised rollers and with many a laughing "yo he ho" finally
+accomplished the task.
+
+The bag had been made by one of the leading aeronautical engineers
+of America, whose factory, strangely enough, was in one of the small
+inland towns of New York State. In a spirit of humor the
+manufactory had been termed the "Balloon Farm," and so famous was it
+that Ned had even planned to spend a part of his summer vacation
+visiting it. When Major Honeywell gave him the opportunity, Ned was
+at once determined to utilize every advanced idea of the skilled
+owner, whatever the cost.
+
+The result was a machine-varnished and, as nearly as such a thing
+was possible, hydrogen gas-proof bag. In the construction of this
+the experienced manufacturer and engineer, who was no other than
+Professor Carl E. Meyers, the hero of hundreds of ascents, had used
+a new machine which applied simultaneously to both sides of the bag
+fabric several thin films of elastic varnish. The bag itself
+consisted of two layers of Japan silk between which was a layer of
+rubber, all being sewed together and then vulcanized.
+
+But the balloon trunk was not opened at once. The pipe to convey
+the gas from the cooler and purifying tank had been brought in
+four-foot lengths of light wood, cemented and shellacked. Eight
+lengths of these were laid to the center of the cleared place and
+then the joints were wound with binding cement tape. When these
+things had been satisfactorily adjusted it was mid-afternoon.
+Everything now seemed ready for the filling up of the generating
+tanks, the inflation, the flight, and "good-bye."
+
+Therefore, a final consultation was held. Wind tests conducted each
+day had shown the prevailing breezes favorable, or at least not
+against the aeronauts. The inflation would require approximately
+ten hours. If begun at once this would make the departure possible
+about midnight. This was not undesirable as the absence of the hot
+southwestern sun would make the gas easier to control. But another
+thing had to be taken into consideration. Only four days had
+elapsed since Elmer and Bob and Buck had started. Were they yet at
+the rendezvous?
+
+"I don't see what difference that makes," said Alan. "We expect to
+sail directly north and east of the foothills. If they have not
+reached their camp they must be nearly there and on the way. We've
+got to locate them with our glasses anyway. Let's start and pick
+them up where we find them."
+
+"True enough," answered Ned. "The way the engine is working, in
+this light favoring wind, we ought to make eighteen miles an hour
+anyway. If we leave at midnight, by five o'clock in the morning we
+can be ninety miles north. The only trouble is in the handling of
+the bag. It's going to take at least twenty men to move the
+inflated bag from the retaining weights to the car and we can't make
+the rigging fast in the dark. We'd better begin work at four
+o'clock to-morrow morning, as soon as it begins to be light, and get
+away about two in the afternoon. I think we'll see our friends
+about seven or just at dark, if we do."
+
+
+
+
+CHAPTER XVII
+
+AN INTERRUPTED FLIGHT
+
+
+And so it was arranged. The young aeronauts thus had all afternoon
+to store provisions, water, gasoline and the instruments. The
+altitude barometer, the recording thermometer, the statoscope and
+recording hygrometer, together with the telescopic camera were each
+given a place on the bridge and lashed to the netting. The
+twenty-five-foot rope-ladder, strong but light, that was to hang
+below the car, and the anchor and drag rope, were attached, the name
+pennant of white with the word "Cibola" resplendent in blue, "turquoise
+blue," explained Ned--was unfurled on its little staff just abaft the
+big propeller, and a new silk American flag was laid out it the stern
+of the car to be run up on its halyards as soon as the bag was attached.
+
+Then came the careful transfer of the liquid hydrogen. One at a
+time the cast iron eases were carried from the building, hoisted
+aboard the car and lashed in place. Before supper Ned had time to
+go to the depot and send a telegram to Major Honeywell, who was yet
+in Chicago. It read:
+
+"Ready for inflation. All O. K. Sail at 2 P. M. to-morrow, August
+11."
+
+He then visited "Saloon Row" and arranged for twenty men to report
+at four o'clock the next morning. No chances were to be taken that
+night. Dividing the hours up to four A. M. into two watches, the
+two boys had supper and Ned was soon fast asleep on the floor of the
+car "trying it out."
+
+At the first blush of dawn the corral gates were thrown open and in
+a short time all the men engaged reported. Some of them were put to
+work dumping the heavy iron filings into the big oak gas generators
+and Ned and Alan began the delicate work of laying out the bag,
+bottom side up the thin silken folds of the golden shell were slowly
+lifted and laid on the ground. When the bottom filling valve had
+been attached to the wooden gas conduits the mammoth sections of the
+long gas receptacle were stretched out on top and then carefully
+smoothed until an even inflation was assured.
+
+This done, the rigging trunk was opened and the seine-like mass of
+delicate hemp cords laid over the bag. No "greasers" were permitted
+to assist in this. Ned and Alan, in bare feet, laboriously but
+carefully drew the silk folds of the bag into the net. When this
+was completed the suspension cords reached out in all directions
+like skeleton fingers. In a quarter of an hour these had been
+attached to the retaining bags with slip knots and then the boys
+were surprised to find that it was already after six o'clock. At
+their best they could not now hope to reach the relief camp before
+nine o'clock and after dark.
+
+Mrs. Buck came with a huge pot of coffee for all, and then followed
+the last step. One by one, borne on the shoulders of the curious
+workmen, the dangerous carboys of sulphuric acid were emptied into
+the generating tanks. The boys guided each step of the men,
+explaining the danger, and the work was finally completed without
+hitch or accident.
+
+At the first bubble of gas the boys felt like doing another war
+dance. But they were "business men" now and had to put on dignity
+in the face of their employees. In two hours the reaction of the
+bubbling acid had sent enough hydrogen through the purifier to raise
+the bag shoulder-high and everything was going splendidly. The boys
+had removed their working clothes and were now in the light but warm
+canvas suits and caps they meant to wear in their flight.
+
+Ned stole away a few minutes and at the bank secured bills to pay
+off the men. On his way back he stopped to invite Mayor Bradley to
+lunch with them on the Cibola and to be present at the "let go." By
+noon the men had been paid and the articles of baggage and tools
+that were to be left behind had been packed, tagged with shipping
+directions and turned over to Buck's wife.
+
+The cigar-like bag, 98.4 feet long and 17.4 feet in diameter, which
+was to hold over 65,000 feet of gas, was now so far inflated that it
+was nearly off the ground. Then Mayor Bradley came. With pride the
+boys bade him climb into the cabin of the Cibola.
+
+"You won't find anything hot in a balloon, Mr. Mayor," laughed Ned,
+"except the reception. Make yourself at home."
+
+On the bridge of the craft the two boys and their guest had
+luncheon. Cold potted chicken and baked beans served on wooden
+plates with hardtack and water, and sweet chocolate for dessert, was
+the simple meal, but it tasted like a feast.
+
+"Have you christened the craft yet?" finally asked the Mayor who had
+absorbed some of the enthusiasm of the young aeronauts.
+
+"That's for you to do," politely answered Ned.
+
+The luncheon was hurried to a finish, for the boys could see that
+the bag needed final attention. It had risen higher and higher and
+was now swaying and tugging at the suspension ropes. Both boys
+alighted and at once began straightening the extension ropes. Here
+and there where the cordage net was out of place they pulled down
+the bag and adjusted the rigging. Finally a little after three
+o'clock, the great case had filled out until its smooth glistening
+sides resembled the skin of a fat sausage.
+
+"All ready!" ordered Ned as he shut of the valve of the cooling and
+purifying box. "Now, every man bear a hand."
+
+One at a time the extension cords were untied from the retaining
+bags, and each of the workmen was given four of the light but strong
+lines. The Mayor himself passed among the men with stern
+injunctions to hold fast. As the last cord was loosed the great
+tugging bag was held wholly by the scared men. Then, with slow and
+measured steps, the double line of assistants advanced to the car
+and along each side of it.
+
+"All steady," commanded Ned when each man had been placed; "now hang
+onto her."
+
+Then he and Alan, springing into the car, began the work of making
+it fast to the bag. There was a place marked for each of the
+extension ropes, and the air ship builders, beginning at each end of
+the car, carefully adjusted and tied the end of each rope to the
+frame of the ship. As the cords were taken from the attendants the
+men took hold of the lower framework of the car, and to make doubly
+sure each man was cautioned to throw his entire weight into the
+work.
+
+At last the final rope was made fast, and three thousand pounds of
+human flesh and muscle were holding the tugging balloon. Ned,
+covered with perspiration, and nervous but happy, was hastily
+connecting the compensating balloon tube with the hand blower on the
+bridge, and Alan had run astern to tie the new national colors to
+the halyards swinging from the end of the bag.
+
+"Hold on," cried Ned seeing that Alan was ready to run up the stars
+and stripes. "Just a moment. Are you all ready, Mr. Mayor?"
+
+"All ready," came the answer from the town official, as he stood on
+a box, his hat off and a revolver in his hand.
+
+"With a western salute I christen this balloon the 'Cibola,'" he
+exclaimed, and a shot punctuated his speech. "Good luck and
+goodbye!"
+
+As the shot sounded Alan's flag ran fluttering upwards. Ned's eyes
+took one final look fore and aft and then he leaned over the car for
+the last words for which all were waiting.
+
+They were on his lips and the eyes of twenty straining men were
+fixed on him to hear the command, "Let go." One nervous attendant,
+apparently thinking the order had been given, threw up his arms with
+a shout.
+
+At that instant there was a second sharp pistol shot, and a quick
+cry from the street outside the corral.
+
+"Hold on there, all of you!" shouted Ned. His dream had rushed back
+to him with a sickening chill. Had some one shot at the towering
+bag? "Hold on!" he yelled.
+
+At that moment there was another shout and Bob Russell, his face red
+with the sun and his shirt wet with perspiration, walked into the
+corral. In his right hand was gripped a revolver and in his left a
+repeating rifle. In front of him, and prodded on by Bob's pistol,
+was the Mexican, Domingo, Jack Jellup's tool and fellow thief.
+
+
+
+
+CHAPTER XVIII
+
+FREE AND AFLOAT AT LAST
+
+
+This is what had happened.
+
+At the time of the rain storm, two days before, Buck and his
+cavalcade were in camp on the bank of the dry Chusco, sixty miles
+north of Clarkeville. The experienced scout knew that a water
+supply was now assured, and he at once followed prearranged orders
+by instructing Bob to return with the smaller wagon. This was a sad
+blow to the young reporter, but it was a part of his contract and he
+knew that it was his duty to obey. And with necessity before him,
+he acted promptly. Emptying the heavy casks, Bob started on the
+back trail at five the following morning, and by night had made
+thirty miles with the light wagon. All day he wondered if it might
+not be possible to reach Clarkeville again before the Cibola sailed.
+
+The next morning, spurred on by the hope that he might do this, he
+started at daybreak. By the middle of the morning he was on the old
+wagon trail and making better time. Some time after two o'clock he
+came up over the rise of the last foothills and saw, eight miles
+away, the glistening shape which he at once knew was the inflated
+balloon. He hesitated a moment and then, unhitching the horses,
+mounted one bareback and began a dash for the town. The animals
+were tired and worn, and progress was slow, but it beat walking, and
+Bob urged them on.
+
+As the young reporter came nearer and the balloon grew more distinct
+he knew that it would be a close call. From time to time as the
+winded horses dropped into a walk Bob wondered why he was making
+such a race. "I can't go with them," he argued. But, like the
+trained reporter, he decided that no effort was wasted that gave him
+new information. And it was something out of the ordinary to see
+the most complete balloon ever made start on a mysterious flight
+into the wilderness.
+
+So he spurred up the horses anew. The hot sun reflected from the
+yellow sands burnt his face and his muscles were sore, but he stuck
+to it. When half a mile from the town he could see the boys on the
+bridge of the Cibola. When a quarter of a mile away he decided that
+he could beat the horses by going afoot, and, throwing himself to
+the ground, he ran onward, knowing that the tired animals would
+follow. Out of breath he reached the edge of the town and stumbled
+on toward the corral.
+
+With head down he plunged forward. Almost at his goal he threw his
+head up for breath just in time to notice a kneeling man with a
+rifle at his shoulder.
+
+"Hey!" yelled Bob with what breath he had.
+
+Then he saw that the man was aiming directly at the balloon swaying
+above the nearby corral fence. He also recognized the man instantly
+as one of the sullen court spectators, and Jellup's crony. The
+rifleman dropped the muzzle of his gun and turned.
+
+"I guess I am something of a gun man," explained Bob later to the
+boys, "for I had that new revolver of mine on the 'greaser' before I
+knew what I was doing myself. I didn't even then realize what he
+was about to do. But I had the drop on him and when I figured out
+that he meant to put a hole in the balloon, why, I just had him
+right. And here he is."
+
+Alan looked at Ned. Both boys were puzzled. A few moment's talk
+with Russell explained the whole situation. The balloon was ready
+and the relief expedition was undoubtedly now in camp awaiting them.
+It needed only the words and they would be off with the inquisitive
+reporter left safely behind. And yet the word did not come. Ned
+and Alan stood looking at Bob, and the reporter gazed in turn at the
+beautiful straining car. Bob's face was a study. He had now made
+some return to Ned for possibly saving his own life, but none of the
+boys was thinking of that. In Bob's fine young face was the longing
+of a child. In Ned's and Alan's faces were the traces of boyish
+sympathy.
+
+The young aeronauts were very close to each other and all were
+silent. Then Alan turned slowly to Ned and with a little quaver in
+his voice whispered, "Shall we?"
+
+Ned made no answer. A smile lit up his face and he sprang down the
+little ladder into the engine cabin followed by his chum. Almost
+instantly the trap door in the floor of the car dropped down. A
+moment later three fifty-pound sacks of ballast tumbled through the
+door to the ground beneath. The bag tugged and strained as Ned
+reappeared above.
+
+"Hurry up, Bob, if you're going with us," he said quietly, leaning
+over the net of the bridge, "and close the door as you come up."
+
+Bob hesitated, as if he had not heard aright, but then he
+understood, and with tears in his eyes be sprang forward. There was
+a jar and Ned knew the new passenger was aboard.
+
+"All ready?" he called sharply from the bridge.
+
+"Aye, aye, captain," came in a choking but jubilant voice from the
+inside of the cabin.
+
+"Stand by, everybody," sharply ordered Ned. And then, as Bob's
+shoulders appeared through the hatchway, the commander of the air
+ship gave a final look about.
+
+"Let go all," he cried sharply. "Everybody!"
+
+For a moment only one clinging workman careened the buoyant craft
+and then, straight up, the Cibola bounded like a rubber ball.
+
+"Good-bye, all," came from Ned, cap in hand, as he leaned from the
+bridge.
+
+There were cheers from below and the Cibola was at last free and
+afloat.
+
+"Sit down here and keep quiet," sharply ordered Ned as Bob crawled
+out on deck. Then the commander of the balloon disappeared below.
+
+There were almost immediately several sharp, muffled explosions, and
+then the white propeller began to turn. The balloon was drifting
+quickly toward the northwest and rising--Bob could see its shadow
+following on the sandy plain. Then the arms of the propeller turned
+faster and faster and a velvet whirr in the cabin showed that the
+engine was falling to work. As the propeller blades settled into a
+steady hum the vibration of the car indicated increased speed. This
+Bob could also detect from the more swiftly flying shadow.
+
+The shadow was also growing smaller, and this meant that the Cibola
+was still ascending. Now the shadow paused and turned. Alan had
+thrown the rudder over and the balloon had responded instantly. The
+aeroplane arms stretched out horizontally on each side of the car.
+Ned, reappearing, took a quick look at the altitude gauge and again
+disappeared. The aeroplane arms dipped in front almost forty-five
+degrees and the current, blown back by the propeller, struck them
+with a jar. The craft again responded and slowly took a downward
+slant.
+
+Propeller, rudder and aeroplane being at work, Ned again appeared.
+
+"Go below," he ordered sharply, "and bear a hand when needed."
+
+Bob did so. Alan was on the pilot platform with his hands on the
+wheel controlling the rudder wires. His eyes were fixed straight
+ahead.
+
+"See that lever," he said, jerking his head to the left.
+
+Bob quickly discovered the aeroplane guider control and sprang to
+it.
+
+"Wait for orders," added Alan.
+
+
+
+
+CHAPTER XIX
+
+THE FIRST FLIGHT
+
+
+The balloon was still sliding downwards and swiftly forward. For
+several minutes the three boys stood in silence. Only the steady
+whirr of the engine and a musical humming of vibrating wires could
+be heard. Bob wondered if they were headed earthward again, for he
+could see the approaching foothills widening out beneath. At last,
+when they could not have been over five hundred feet from the
+ground, came the quick order:
+
+"Right the planes."
+
+Bob was almost caught napping, for he was busy looking through the
+window. But his hands responded instantly, and he almost choked
+with chagrin to find that he had started to throw the lever the
+wrong way. But his recovery of himself was instant and with a
+desperate pull he forced the guiding planes back horizontally. The
+glide downward stopped and the Cibola shot forward with renewed
+speed.
+
+On the bridge Ned held a fluttering chart before him.
+
+"How is she heading?" he called to Pilot Alan at the wheel. With a
+glance at the compass before him Alan promptly responded:
+
+"Nor'nor'east."
+
+"Make it north by east."
+
+A quick slight movement and a strain told that the alteration had
+been made.
+
+"North by east it is," sang out Alan.
+
+"Keep her there," was the echoing response.
+
+Bob was thrilled. Every word was to him a joy. Everything had
+happened so quickly that he hardly knew what it all meant, but he
+was happy. Even the sudden discipline pleased him and he was glad
+to be a part of it. The knowledge that a younger boy was giving him
+orders did not bother him. He had skill in his own line, but he saw
+and realized that in the Cibola Ned Napier was in charge and meant
+business.
+
+For some time then no word was heard. The Cibola, speeding, swiftly
+onward, had crossed the low foothills and was pulling herself
+through the almost breezeless air like a modern liner, five hundred
+feet above the ground. She was holding her course beautifully.
+Then Ned appeared and tested the gas exhaust and oil feed of the
+engine.
+
+"Were you ever in a balloon before?" he said when he had finished,
+turning sharply towards Bob.
+
+"Never," answered Bob, glad enough for a chance to say something.
+
+"Have you any matches?" somewhat sternly asked the commander of the
+Cibola.
+
+"Sure," replied Bob reaching in his pocket and finding one.
+
+"Any more? All of them."
+
+Surprised, Bob searched his clothes and discovered a few more which
+he obediently handed over to his superior officer. Noting the look
+of surprise in the reporter's face Ned laughed.
+
+"The first rule in a balloon is 'No fire.' But beginners forget,
+sometimes; we can't take this chance with you."
+
+"Take anything I have got," answered Bob with his old smile, which
+had now been in eclipse for some time, "and if I can speak at last I
+want to say that you boys are white, clean white, through and
+through. Didn't you need that ballast?"
+
+"We may need it badly," said Ned, laughing. "If it should become
+necessary I suppose you won't mind if we throw you overboard."
+
+"No," retorted Bob, "not if it is a little at, a time. But you're
+bricks--both of you--if I thank you I'll cry." The tears were again
+in his eyes.
+
+"Well, it wasn't the thing to do, I suppose," said Ned turning away,
+"but you looked so hungry to go, and I knew what it meant. So I
+thought we'd just give you a little ride up to the camp."
+
+"Yes, of course," answered Bob slowly as his hopes fell. "Put me
+out wherever you like," he added.
+
+"You can go up now and have a look around," said Ned at last, "both
+of you. I'll take the wheel."
+
+The relieved boys scrambled onto the bridge deck. Night was coming
+on and the mountains to the west were already black. Evening
+shadows were lengthening on the sloping plains beneath and a gentle,
+rising breeze flapped the flag and pennant and swayed the bag above
+them. Beneath, the Chusco wound its half dry course and off to the
+east a blue haze, melting into the unending sand, told of a treeless
+and waterless waste.
+
+"And there," exclaimed Alan at last, pointing off to the northwest
+where snow-capped, ragged peaks rose out of a black jumble of
+mountains, "are the Tunit Chas and the land of our dreams.
+To-morrow--"
+
+"One moment," interrupted Bob quickly. "I think you are forgetting.
+That is your secret and not mine."
+
+Alan flushed. "I forgot," he said with a stammer, "and I thank
+you."
+
+"I can't afford to make you sorry you brought me," added Bob, "and
+you are not going to be."
+
+There was a little jar. The propeller slackened a trifle, and Alan
+explained that Ned had headed the Cibola another point into the
+freshening breeze.
+
+"Steward," said Ned from below, "it's seven o'clock and I'm hungry.
+Besides, it's getting pretty dark down here."
+
+Alan and Bob looked at each other and laughed.
+
+"That certainly means me," exclaimed Bob, and both boys clambered
+below. With Alan's help Bob made his first examination of the store
+room.
+
+The meal was rather haphazard, as the boys, carried away by the
+excitement of their new flight, had neglected to eat when it was
+light. But water and hardtack were easily accessible, and Alan,
+taking the first two cans at hand, found happily that they contained
+sardines and veal loaf.
+
+"We'll eat on deck," suggested Ned, as he set the wheel and had
+another look at the engine, which had not missed a revolution.
+
+The night that greeted them was magnificent. The moon was not yet
+up, but the stars were scintillating in the inky sky and the deep
+silence of the clouds and desert was about them. Bob gazed as if
+spellbound. The charm of the night appealed to him as it did to Ned
+and Alan; but with it his brain formed phrases--"cloudland by
+night," "a dash to the stars." The reporter in him was thinking
+"copy."
+
+"Hey, there, wake up!" cried practical Ned.
+
+Bob flew to his task; with a turn he had the veal loaf can open and
+had dumped its contents in the wooden plate held by Alan.
+
+In another moment he would have thrown the empty can overboard but
+the watchful Ned, ready for another lesson in aeronautics, caught
+his hand.
+
+"Don't you like the route we are taking?" laughed Ned.
+
+Bob's face showed he did not understand.
+
+"The loss of the weight of that can might send us sparing upward a
+thousand feet," explained Ned dryly, "so don't cast over ballast
+until you get orders."
+
+Bob shook his head. "Well doesn't that beat all," he exclaimed.
+
+As night fell and the air grew heavier, the barometer showed that
+the Cibola had a tendency to rise. The aeroplanes were readjusted
+and then for an hour the craft sped on untouched. At eight o'clock
+Ned said:
+
+"We haven't traveled over eighteen miles in an hour and we've been
+afloat four hours. If we are still over the Chusco and Elmer and
+Buck are at the appointed place we may be within ten or twelve miles
+of them."
+
+"They are going to burn three small camp fires set in a triangle,
+you remember," remarked Bob.
+
+"Therefore," suggested. Ned, "all keep a sharp lookout."
+
+At half past eight Ned showed some concern. No lights had been
+sighted and the reckoning showed that they must be within two or
+three miles of the probable location of the camp. Another fifteen
+minutes went by, and yet no signal fires were seen. They had now
+passed over the junction of the two rivers, if their calculations
+were right, and Ned and Alan were in a quandary.
+
+"It's no use to go on," commented Ned; "so we'll just make a wide
+circle and see what we can find."
+
+It was also useless to look below. In the darkness there was no
+sight of either river or desert.
+
+"It we don't pick them up in that way," continued Ned, "we'll
+descend and tie up for the night."
+
+Both Ned and Alan went below, and with the engine shut down to half
+speed the Cibola was turned on her course in a wide sweep. Bob
+alone watched with anxious eyes, until he was joined in a short time
+by Ned. There was no sound but the soft chug-chug of the engine,
+and for some time neither spoke. The breeze of the early evening
+had died and there was not a breath of air. Alan in the dark cabin
+below held the wheel and Ned and Bob alone, hanging over the side
+net, watched and listened in vain.
+
+
+
+
+CHAPTER XX
+
+FIGHTING INDIANS WITH A SEARCHLIGHT
+
+
+"Stop her!" It was Ned's voice in quick command. The young
+aeronaut, peering over the side of the car of the Cibola into the
+black night, had suddenly seen something that prompted the order.
+It was a distant flash of light. This was followed by an echoing
+explosion. The other boys heard the explosion and all instantly
+knew that it was a shot from a firearm. Almost before Alan could
+shut off the power Ned had disappeared into the cabin to help head
+the balloon in the direction of the spurt of fire. The Cibola
+slackened speed and they waited, drifting slowly toward the east.
+Then, suddenly, and almost together came two streaks of fire and two
+more explosions.
+
+"One of them might mean a signal," said Ned gravely, "but they were
+not from the same spot. If it were Elmer he would have the three
+fires. If it is Elmer and Buck and they can't make a fire and are
+shooting I am afraid it means trouble."
+
+"It may mean Indians," suggested Bob, "and they may have put out
+their fires for safety."
+
+"They might even be holding off an attack of some kind," added Alan
+anxiously.
+
+Just then there was another crack of a firearm now a little nearer.
+The Cibola was drifting directly toward the sound, but very slowly,
+and would soon have lost all headway.
+
+"I don't want to be presumptuous," said Bob in a low voice, "but
+can't we land and find out what the trouble is?"
+
+"We can find out without landing," replied Alan.
+
+It was so dark in the cabin that the boys could only dimly see each
+other, but Ned was groping about near the silent engine. In a
+moment he had secured from the ammunition case a storage electric
+light, and cautiously shading the lens with his cap he asked Bob to
+hold it. Then he turned to his chum.
+
+"I didn't know just how we would use our little drop light," he
+began; "but it seems that the idea wasn't half bad. There is a
+tribe of Indians not far from here that would steal a horse or cut a
+man's throat quickly enough--the renegade or Southern Utes." As he
+spoke he was digging in a chest extracting various small parcels.
+"Not even the other Indians have any use for the Utes. And there is
+only one thing to do. We must first find out if our friends are
+below."
+
+With the help of the flashlight Bob could we that Ned held in his
+hand a large, high candle-power incandescent bulb and was adjusting
+it in a silver reflector.
+
+"With an electric light?" exclaimed Bob.
+
+"Why not?" replied Ned. "And the help of our little dynamo."
+
+Ned took the flashlight, held it under his coat, and crawled around
+in front of the silent engine. "It's here," he explained for Bob's
+benefit, "and I am just throwing the gear onto the propeller shaft."
+
+"Well, if you are afraid to show this little light why aren't you
+afraid to show a brighter light?" asked the observing reporter.
+
+Alan answered him.
+
+"We are only afraid because it might draw an attack from some
+observer. Balloonists are never safe from meddlesome persons or
+worse. But there isn't the same danger if the light isn't on the
+balloon."
+
+"Sure," said Bob. "I understand that. But you can't hold it very
+far away."
+
+"No," answered Ned, "that's why we braided two good copper wires in
+our drag rope." As he said this he opened the trap door in the
+floor of the cabin and feeling about in the dark soon had hold of
+the coiled drag.
+
+"I guess I'm dull," began Bob.
+
+"No," interrupted Alan, "only you haven't given two or three years
+to figuring out the possibilities of an air ship."
+
+Ned was attaching the bulb, reflector down, to the end of the rope.
+
+"That rope is three hundred feet long. A light at the end of it is
+quite a way from our bag.
+
+"Oh, I see," exclaimed Bob at last. "If we find Indians and they
+shoot at our searchlight they are pretty sure to miss us."
+
+"That is the theory," answered Ned.
+
+And then the plan in Ned's mind was explained. The engine was to be
+started at quarter speed, which meant that the sound would be
+imperceptible; and, lying on the floor of the cabin, Ned was to
+direct the movements of the ship, with Alan at the rudder wheel and
+Bob at the aeroplane guider.
+
+"A quarter to ten o'clock," said Ned glancing at his watch as he
+shut off the concealed flashlight, "and now start her up."
+
+As Alan started the engine and it began to turn the propeller they
+could tell by the light breeze that the car was moving again, but
+very slowly. The other boys could also hear Ned delicately paying
+out the long drag rope. At last it was all out. Then Ned crawled
+forward again to the dynamo and up to the partly open floor of the
+car and whispered that he was ready. The multiple gear was already
+speeding the little generator swiftly.
+
+"Lie down on the floor and watch," murmured Ned softly, "I'm going
+to turn her on."
+
+Alan and Bob did so. As their two heads filled the open trap in the
+cabin floor there was a click and then, as if some necromancy had
+focused the sun on a part of the darkened world, a circle of light
+seemed to spring out of the desert beneath. Yellow, with here and
+there a ragged rock and a sage brush or two, the shadows of the
+rocks and brush black like spilled ink, and the sand glaring back at
+them with almost quivering brightness, the circle shot back and
+forth as the light followed the swinging rope. But no living thing
+was in sight. A click and all was black again.
+
+"Nothing doing," exclaimed Bob.
+
+"Wait," suggested Ned, "persons we couldn't see may have seen them."
+
+Almost as he spoke there was another quick report.
+
+"Did you see the flash, Alan?" asked Ned eagerly, for he had been
+busy with the dynamo.
+
+But Alan was already at the wheel, and again the car swung from its
+course.
+
+"Wait," he exclaimed, "turn it on again when I give the word."
+
+After perhaps two minutes he gave the signal and again Ned flashed
+the gleaming bulb. Again the circle sprang apparently out of the
+black ground. As the car drifted forward the black blotched golden
+sand ran the opposite way like a whirling panorama. A coyote
+sprang, dazed, from a clump of bushes and back again, but that was
+all.
+
+"Give him another chance," whispered Alan, and the light flashed
+out.
+
+"Listen," exclaimed Bob breathlessly, "wasn't that a cry?"
+
+Another moment and the sound came again.
+
+"Elmer!" exclaimed the two air ship boys together.
+
+The Cibola swung instantly at Alan's quick touch. Again the light
+flashed. Sand and rock and brush. The brilliant circle of light
+shot here and there, but the anxious watchers saw sign of neither
+friend nor foe. Then like a flash the level plain dropped into the
+sudden slope of a coulee and the darker shadow of water blotted out
+the glare of sand.
+
+"The river," whispered Ned. "Now watch sharp."
+
+As the light was blotted out this time Alan swung the wheel again.
+He knew instantly that they were on the wrong track, as they were
+going east and crossing the Chusco. Elmer and Buck would not cross
+the river. The camp was to be on the west side.
+
+"Follow the river," ordered Ned quickly; "the west shore."
+
+In order that the Cibola might be laid on the new course Ned threw
+on the light switch again. As he did so and the light flashed there
+was the sharp crack of a rifle and the light was gone.
+
+"Turn her on," exclaimed Alan; "I want to get a line on the river
+bed."
+
+Ned laughed. "I'll need a new bulb first. Some one down below
+turned it off."
+
+"What?" exclaimed the other boys together.
+
+"Shot out," calmly retorted Ned.
+
+
+
+
+CHAPTER XXI
+
+A CORDITE BOMB AND ITS WORK
+
+
+In a moment the boys were hauling in the rope and Ned was back in
+the cabin after a new bulb which he secured and attached in the
+dark.
+
+"Now give her a swing," he said as Bob again lowered the rope. "It
+will make it harder to hit."
+
+When Bob announced that all the rope was paid out Ned snapped the
+switch again. In spite of the gravity of the situation all the boys
+were tempted to laugh. A brilliant green glow shot down. An
+emerald circle of light flooded the ground beneath.
+
+"If anyone sees that they'll sure think it's a drug store,"
+suggested Bob.
+
+"'Or a sign of the Great Spirit, perhaps," added Ned soberly, "it
+may help us in more ways than one, if Indians are--"
+
+"Look," hoarsely shouted Alan, "there, over there!"
+
+But his words were superfluous. The three boys saw the same thing.
+And then as the wide swaying of the bulb swept the gnome-like
+picture in green from view Ned threw himself over and shut off the
+engine.
+
+Not a hundred feet beneath the brilliant bulb the precipitous bank
+of the river had again shot into the circle of light. At the very
+edge of the cliff stood the big freight wagon. Behind it, between
+the wagon and the steep river bank, stood two horses. At one end
+two more lay prostrate on the ground. In front a light barrier of
+boxes and barrels rose a few feet from the ground. And there, a
+rifle at his shoulder, knelt Elmer Grissom, their friend and
+servant. Buck was nowhere in sight.
+
+Their worst fears were realized.
+
+As the dramatic picture flashed from view each boy knew that it was
+time to act.
+
+"What's to be done?" exclaimed Alan, his voice choking.
+
+"There can't be many of them," answered Ned finally, as if thinking,
+"or they would pushed their attack. If we could locate them the
+rest would be easy. Let Bob take the wheel and try to get over the
+wagon again; I have an idea."
+
+The Cibola again answered the rudder and circled, Ned flashing the
+bulb until the river came beneath them. This required but a few
+moments, but, before the craft had gathered momentum on the way
+back, there were four shots almost together about three hundred
+yards to the right of where they supposed the wagon stood, and a
+quick reply from the river bank.
+
+"Our light did it," exclaimed Alan, "they are rushing the
+barricade."
+
+"Indians don't rush together, if it is Indians," replied Ned. "Keep
+on up the bank, Bob. It's risky for Elmer," he added with a husky
+voice, "but we've got to take chances."
+
+Again the light flashed. Ned and Alan hurried to the bridge.
+
+Within its circle and almost together, sealing the seamed and hard
+bank of the river, were five dark figures. As the powerful light
+encircled them the crouching figures sprang backwards. But they
+were not quicker than the alert and prepared Ned Napier. A small
+round object shot downward from his hands. The glare of flame as
+the missile struck true and the thunderous roar that hurled the big
+bag of the Cibola sideways told that the cordite bomb had done its
+work well.
+
+Bob was speechless. Ned and Alan were already in hurried
+consultation. They could not count on fortunately finding the other
+besiegers all together, "'and there are at least four more," said
+Ned. The rescue of the lone besieged lad was not an easy problem.
+The boys believed themselves now just above the wagon again, but
+they were afraid to draw possible fire to the barricade by showing
+another light.
+
+The hurling of the bomb overboard had shot the Cibola heavenward
+like a bird. Before they realized it the aeronauts had mounted up
+at least two thousand feet. They then began maneuvering to regain
+their position. But this was not so easy. A flash of the suspended
+searchlight gave them not a trace of their bearings and it was
+plainly apparent they would have to use time and patience in
+recovering the location of the besieged wagon. Using their best
+judgment, they put the aeroplanes to work, and, circling slowly, the
+Cibola gradually came nearer and nearer to the ground. After ten
+minutes or more the car gave a sharp bound upward.
+
+"The drag has touched the ground," exclaimed Ned.
+
+The aeroplanes were righted, the engine was stopped, and again the
+balloon was drifting. There was not a sound to guide the aeronauts.
+The contact with the ground had broken the bulb and it was not
+replaced. For aught the rescuers knew they might be again directly
+over the wagon. Not a shot had been fired since the roar of the
+explosion, but there was no reason to believe that the yet living
+besiegers had withdrawn.
+
+"More likely planning a final attack," suggested Alan.
+
+Again a council was held.
+
+"We've got to take the risk," said Ned at last in desperation; "we
+can't do anything up here."
+
+And then, with Alan's approval, the propeller was set turning again,
+but so slowly that the big balloon was just moving under control.
+The aeroplanes were also set to bring the craft nearer the ground
+and, as a precaution, Bob was sent onto the bridge with an open
+knife to cut away ballast if sudden ascent were needed. The drag
+rope had been brought in. There were no means of knowing how near
+the car might be to the earth and the suspense was decidedly trying.
+
+"I guess I can come a little nearer finding out," exclaimed Ned
+finally to the others in a whisper.
+
+Alan did not know what he meant, but he resumed his place at the
+wheel. Ned had disappeared in the dark.
+
+"Where are you, Ned?" asked Alan anxiously at last.
+
+The answer came from beneath the car.
+
+"Only down here, but I'm going lower," Ned replied, again in a
+whisper. "Be ready with that ballast."
+
+A perspiration of fear broke out on Alan's body. He sprang to the
+open trap door.
+
+Just discernible in the darkness was Ned's slowly retreating form.
+
+He was climbing down the twenty-five-foot rope landing ladder with
+only his own strong grip and the spruce rungs to save him from
+death.
+
+There was nothing to be said or done. Bob did not know what was
+going on below, but he knew that he had a task set for him, and in
+the long silence that followed while the Cibola settled lower and
+lower and drifted on and on in the dark he stood, knife in hand, at
+the ballast bags.
+
+
+
+
+CHAPTER XXII
+
+A THRILLING RESCUE IN MID-AIR
+
+
+Buck, the guide, and Elmer Grissom had reached their appointed
+rendezvous at two o'clock that afternoon. The hot journey had been
+tedious and uneventful. Only at the half-breed settlement twenty
+miles north of Clarkeville had they seen a human being. Therefore,
+after they had been in camp about an hour, even the vigilant,
+experienced Buck was startled to observe suddenly a solitary
+Indian--his horse as statuesque as himself--watching them from a
+knoll some two hundred yards distant.
+
+As the old scout raised both hands in signal of peace the Indian
+rode forward. The man was not in the Indian panoply of the old
+days, except that he wore moccasins and had two bands of red and
+yellow paint on his broad, dark face. A black wide-brimmed hat, a
+faded blue shirt and trousers completed his outfit.
+
+"How?" exclaimed the Indian.
+
+"Navajo?" answered Buck.
+
+"Ute!" came the answer. "Where go?"
+
+"Right here," said Buck good-naturedly, pointing to the ground.
+
+"Ute land!" retorted the Indian without a trace of expression in his
+face.
+
+"No," retorted Buck sharply, "not Ute land. Ute land there,"
+pointing north, "in Colorado."
+
+"Ute land!" exclaimed the red man again, this time scowling.
+
+Buck only shook his head.
+
+Then the Indian suddenly threw himself from his horse, strode to the
+wagon and threw up the tail curtain. Safely stored therein he saw
+the protected tins of gasoline.
+
+"Whisky?" he exclaimed.
+
+"No," laughed Elmer, "not whisky."
+
+"Whisky," repeated the stranger turning towards Buck; "drink!"
+
+But Buck shook his head.
+
+With out another word the Ute walked haughtily to his horse, threw
+himself upon it, and, clasping his heels to its sides, rode quickly
+away.
+
+"I'm sorry," exclaimed the veteran at last.
+
+"I had no idea that there were Utes around here."'
+
+"He doesn't seem dangerous," commented Elmer.
+
+"No," answered Buck, "men who'd cut your throat for a horse never
+do. The chances are he isn't alone."
+
+Elmer looked up in surprise.
+
+"We'll just make sure," exclaimed Buck, making as light of the
+affair as possible. "I don't want to lose my horses and you don't
+want to lose your freight. We'll make ourselves ready in case our
+friends come back to make us a little visit."
+
+And as night came on and Elmer helped Buck draw the wagon close to
+the river bank, where approach from the rear would be difficult, the
+boy began to realize what it meant to get away from the telegraph
+and policemen and law and order. And when the experienced scout
+unloaded a portion of their heavier freight and began to build a
+small barrier Elmer's usual joviality cooled into silence. The
+three piles of brush and driftwood from the river were laid out some
+distance in front of the camp in preparation for the agreed signal
+fires and then, before the sun went down, the scout and his
+companion made their camp fire and had supper.
+
+"What do yo' expec' dey'll do?" asked the colored lad at last.
+
+"Well, you can't tell. Injuns are puzzles. When they steal they
+steal in the dark. When they fight they fight at daybreak."
+
+"What do yo' suggest?"
+
+"To tell the truth, son," answered Buck, "there ain't much to do but
+keep yer eyes open and pop it to the first red horse thief ye see
+crawlin' around in the night."
+
+"Hadn't we better light our signal fires?" asked Elmer.
+
+"There won't be any signal fires to-night," replied Buck, slowly,
+"if you want my advice. It's one thing for a bluffin' Ute to walk
+up in the daylight when you've got a fair chance to give him as good
+as he sends, and its another thing for him to get a bead on you a
+sittin' in the light o' yer camp fire--him in the dark."
+
+Elmer saw and understood.
+
+So night fell in silence with Buck and Elmer keyed up and ready to
+meet any possible attack.
+
+Nothing happened until several hours had passed. Neither Elmer nor
+Buck were any the less alert, however. The old scout was pacing up
+and down in front of the barricade and perhaps a hundred feet from
+it. Elmer could just hear his soft footfalls in the sand. Suddenly
+these ceased. Almost at the same moment there was the crack of
+Buck's rifle, a groan and a moment later the scout was inside the
+barricade.
+
+"I guess I got him all right," he whispered, "he was makin' too much
+noise."
+
+This was the shot Ned heard miles away in the Cibola.
+
+Again for some minutes there was no sound and then, suddenly and
+from the left, came a spit of flame in the dark. Almost before
+Elmer heard the explosion Buck's gun had spoken in reply. Both
+bullets went wild, but Buck explained that it was necessary to give
+shot for shot, "and right at 'em," said Buck, "as it takes a little
+o' the ginger out o' them."
+
+But the besiegers had undoubtedly widened out. The next signs of
+them were two shots, almost together. Elmer's rifle made quick
+reply, but, to the boy's surprise, Buck failed to fire in return.
+The scout had disappeared from his companion's side. Before Elmer
+could call out he heard a rush at the end of the barricade, and then
+two explosions almost together and not ten feet away. He could not
+describe the sound that followed, but he knew that it meant the
+convulsions of human beings in agony. He whispered his companion's
+name, but there was no answer--only a gasp.
+
+In the black darkness the colored boy, revolver in hand, crawled
+forward. At the end of the barricade Buck's body was lying. As the
+boy's hand fell on the old man's breast he knew that it was blood he
+felt.
+
+"Buck," he whispered, "Buck! Is yo' hurt?"
+
+He put his arm under his friend's head. For a moment the unconscious
+form yielded and then convulsively straightened. Elmer knew that his
+companion and protector was dead.
+
+With strength that he did not know he had Elmer laid Buck's dead
+body behind the little wall of freight boxes.
+
+Then, as if by intuition, he sprang forward and found what he
+suspected--the unmoving form of an Indian. Unable to see, Elmer
+quickly felt over the adjacent ground with his hands and discovered
+the dead Ute's rifle. The revolver was gone. In the same manner he
+recovered both Buck's rifle and revolver, and then prepared to do
+his duty--to protect his employer's goods so long as he could.
+
+He was scarcely entrenched again, with the three magazine rifles
+laid on the barricade before him, when his straining ears heard a
+new sound. Far away and faint, but meaning only one thing, the soft
+chugging of a motor. The Cibola! There could be no doubt of it.
+The instant feeling of relief was shattered even as it gave Elmer
+new courage; to attempt to light the signal fires would probably
+mean instant death. And without them how would his friends know his
+position or peril? But one thing he could do; and even knowing that
+it would mean an answering shot from the skulking horse thieves he
+discharged his revolver into the air.
+
+Then the sound of the motor died away and the long minutes dragged
+by. When it began again, and more softly, the sound was nearer.
+Nearer, and nearer it came and then the circle of light fell on the
+wagon and was gone. "At least they know where I am," thought Elmer
+to himself, and settled down courageously for renewed attack,
+determined to hold out to the last. At this moment came the shot
+that put out the Cibola's light.
+
+The nervy boy had been tempted to abandon the wagon and follow the
+light, but his second judgment was against this. "If they can, the
+boys will come back," he argued, "and I'll only get out of this when
+I have to."
+
+To Elmer's surprise the attackers had been strangely silent for some
+time. With more experience he would have known that this meant even
+greater danger, but he only hoped it was due to the distracting and
+mysterious flying light. Then the sepulchral green light burst out
+in its funnel-like volume. It was coming back. It flared, went
+out, shot over the distant sands again like a searching' eye and
+then began moving straight up the river bank towards the wagon.
+Then came the earth rending explosion. Nor could the besieged boy
+know even then that Ned's well-aimed bomb had sent five Utes to
+their last sleep.
+
+When the sound of the explosion had died away and Elmer had
+recovered himself--for the shock had thrown him forward on the
+barricade--the whirr of the Cibola's motor was again far away. But
+it was directly above him!
+
+As if the attackers had been paralyzed by the explosion, the long
+interval continued without a shot. Then suddenly, from the right
+and left and front, the real attack began. One shot sounded as a
+signal, and then from a half circle before him half a dozen bullets
+tore their way towards the boy and his barricade. Most of them went
+wild. Two hit the boxes and half stunned the lone guardian behind
+them. The assailants did not know that one of the two white men was
+dead, and Elmer, in hopes temporarily to deceive them, fired two of
+the rifles at the same moment.
+
+But his enemies were closing in; the half circle was growing smaller
+and the crash of the bullets in the wagon above him and in the
+barricade in front told the boy that the end could not be far away.
+To the right in the direction of the explosion there was a gap in
+the fast closing circle. It was folly to delay longer. If escape
+were possible, it was in that direction. He would make one
+desperate attempt. One shot remained in his rifles. Putting it
+where he thought it would do the most good, and catching up the two
+yet full revolvers, the colored boy crawled under the wagon and
+crept hastily along the river bank.
+
+And yet he did not dare to attempt to pass the end of the Indian
+semi-circle. It was one chance in a thousand. Throwing himself on
+the ground, he waited. "Crack!" It was the rifle of an Indian, not
+fifty feet away and coming nearer. The stealthy footfalls told
+Elmer that his foe was heading straight for the river bank and that
+he was in the Ute's path. Then he could hear the Indian's deep
+breathing. Detection was inevitable.
+
+One last thing remained to be done--to kill the Indian and make a
+dash forward down the river bank. And he must act before his foe
+discovered him. Elmer's revolver flashed fire and he saw his foe of
+the red and yellow face bound into the air and then topple forward
+with a cry of anguish.
+
+The boy turned, but too late. Directly in front he heard the sudden
+shouts of other Indians. The river at his back! Flight down its
+cement-like bank was impossible. He might plunge forward and pray
+that the water was beneath.
+
+The death cry of the man he had shot and the echoing yells of the
+Indians behind him had been taken up by others. He knew the
+determined savages were making a final rush. Indian cries seemed to
+come from the very ground at his feet. He hesitated no lodger.
+
+As he turned to the river a sudden and strange wave of cool air
+struck down on him from above. Without reasoning he paused. That
+pause saved his life. In that swift moment he heard the low creak
+of something straining. His eyes pierced the black about him. Was
+it a shadow? Something was brushing by him like a great bird asleep
+on the wing. Then it was on him.
+
+"Ned?" It was only a whisper but it was enough.
+
+"Elmer, here, quick!"
+
+Even the whisper had brought an instant shot, but the colored boy
+had hurled himself toward the voice and an instant later a strong
+young arm was about the besieged lad.
+
+It was Ned Napier on the swaying ladder of the Cibola.
+
+"Cut away," came the low quick order and before even the nearby
+besiegers could locate the sound Bob Russell, high above, had
+slashed the lashings of a bag of ballast. The big balloon sprang
+forward, Elmer dangling in the air, and then settled again to the
+earth as the desperate colored boy found the last rung of the ladder
+and clung fast opposite his rescuer.
+
+"Another, another," called Ned springing up the fragile length of
+the doubly laden ladder.
+
+A thud on the ground told where another bag of ballast had fallen.
+The crash of the fallen fifty-pound bag of sand probably saved the
+Cibola. Shot after shot poured in the direction of the sound,
+although the Cibola, dragging forward, yet refused to rise. Elmer,
+at the bottom of the ladder, was helping the car onward in low
+bounds by touching the ground with one foot.
+
+Then the air craft settled again. Elmer's weight was too much. A
+mad thought came into the boy's brain. The Indians had located the
+new invader and yells nearby told that hot pursuit was already being
+made. Then the spit, spit, of new shots showed the risk the boys
+had taken. Elmer realized it. Should he hang on and endanger the
+lives of his friends, or should he let go?
+
+There seemed no time to think, but the boy's hand had already
+loosened when out of the black came the hot breath of the foremost
+pursuer. As the savage sprang forward Elmer's free arm gave him a
+blow full in the face. At the same instant the Cibola sprang upward
+like a bullet. A volley of shots rang out below, but they were too
+late. The balloon had saved Elmer's life, and even before the lad
+had made his way up the swaying ladder into the cabin it was a
+thousand feet in the air.
+
+
+
+
+CHAPTER XXIII
+
+CAMP EAGLE IN THE MOUNTAINS
+
+
+It seemed too wonderful to be true. But words were proof enough
+that Ned Napier and Alan Hope had found a new use for dirigible
+balloons. Faithful Buck's death was more than the loss of a
+companion. In the short time the boys had known him he had shown
+that under his rough frontier bearing he was a brave and honest man.
+
+"We can't go back now," explained Ned, "and we can't afford to land
+and wait for day. We can't all stay in the Cibola, and those of us
+who are landed must be left in a safe place. Our work," he
+continued turning to Bob, "is in the Tunit Chas Mountains, thirty
+miles west of here. It seems as if you had to know it. We'll go
+there to-night and land, if we can, on some isolated and inaccessible
+plateau. We'll make that our new relief camp and you and Elmer must
+take charge of it. To-morrow Alan and I will return in the Cibola to
+our abandoned wagon, bury Buck and bring away such of our stores as
+may be left. It's going to be a great loss, for I suppose the
+Indians have stolen everything. If the gasoline is gone it will cut
+short our work in the mountains."
+
+"I don't think it will be lost," said Elmer, quietly. "We tried to
+save it. We rolled it into the river."
+
+"But it will float away," exclaimed Alan.
+
+"Unless de tins caught on in de drift in de bend jes' below,"
+answered Elmer. "I seen four ob de eight tins dar befo' dark."
+
+"That's what I call genius," exclaimed Ned. "Elmer, you're a brick!
+And now our course is due east at half speed. By daybreak we'll be
+over the Tunit Chas. Until then, the rest of you turn in. I'll run
+the ship."
+
+Fifteen minutes later, despite the nerve-racking experiences of the
+momentous day, Alan, Bob and Elmer were wrapped in their blankets
+and sound asleep on the bridge deck of the Cibola.
+
+The night passed slowly, but Captain Ned stood the long trick at the
+wheel, happy and content. To feel the Cibola, the product of his
+youthful genius, at last moving forward in obedience to his
+slightest touch drove all thought of fatigue and sleep from him.
+
+But, above all, the early light of the coming day was to reveal to
+him a sight of the land of his hopes. There, before him, were the
+Tunit Chas; peaks and chasms of unsolved mystery wherein the
+centuries had held close their secret. Many trials had blocked his
+way. Was he now about to reap the reward of his labors? Did the
+hidden city of Cibola lie somewhere below him? Or were the Palace
+of the Pueblos and the Turquoise Temple but empty myths?
+
+The young aeronaut's present plans were simple enough. The Cibola
+had now been afloat twelve hours and nearly half her gasoline was
+exhausted. More than once in the night Ned had noticed that the
+balloon was settling lower and he had been forced to maintain his
+level by casting over ballast. It was apparent that they were
+already losing gas.
+
+In boyish impulse and sympathy they had made Bob Russell, the young
+reporter, a third and unexpected passenger, and accident had forced
+them to add Elmer Grissom, their colored friend and servant. And
+these extra occupants of the car must be landed at the earliest
+opportunity.
+
+This became imperative now because, the relief and supply station on
+the Chusco river having been destroyed, the Cibola must add enough
+ballast and gasoline to make its exploring tour in the mountains in
+one journey. The original plan had been to make quick dashes to
+the camp on the Chusco for gasoline and then return to the
+mountains. To provide for this new weight the two new passengers
+and a good portion of the air ship's stores must be landed. And the
+most feasible plan seemed to be to set up a new emergency camp in
+the heart of the mountains.
+
+Many things might happen to the now perfectly working balloon. And,
+even if cast away in the mountains, it was no part of Ned and Alan's
+plan to cease searching for the temple of treasure until dire
+necessity drove them from it. In case wreck and privation came it
+would be comforting to know that somewhere in the same wilderness
+food and friends awaited them.
+
+The first glow of the sun painted for the ever watchful pilot a
+picture beyond the possibilities of brush and canvas. Here and
+there out of the blackness below sprang rosy points, the sun-tinted
+peaks of the Tunit Chas. Down the mountain sides, like rivers of
+silver pink, fell the sun's light. Then the valleys began to open
+out of the chasm of night-dark canyons wrought in the wilderness of
+the mountain sides. Here and there, oases left by the devastating
+hand of time, rose high plateaus, tree-crowned and verdant. And
+then, higher up among the white peaks, sentinel-like, stood giant
+tables whose brown tops and precipitous sides told of inaccessible
+and arid wastes. "And somewhere," said Ned to himself, "in this
+Titanic chaos lies the object of our search."
+
+Starting at half speed, Ned had soon reduced the engine to quarter
+speed. When he aroused his sleeping companions Wilson's peak, their
+chief landmark, was just in sight far behind. His calculations
+placed the present location of the Cibola thirty miles from the
+Chusco river and just over the eastern Tunit Chas Mountains.
+
+"All hands turn to," shouted Ned cheerily, "and stand by to make a
+landing."
+
+There was a scramble, a rubbing of yet sleepy eyes and then an
+outburst of admiring wonder. The Cibola had sailed over two broken
+ridges enclosing an irregular, broken valley and was now looking
+down on a shelf-like plateau abutting on the second ridge and west
+of it. On three sides the plateau dropped precipitately into a
+lower rock-strewn, valley. On its eastern side it joined the still
+higher ridge. A pine forest crowned the top of the shelf-like
+mountain side and then ran up to the higher slopes until the carpet
+of green faded into the brown wastes of the timber line. In the
+very center of the wilderness of trees glistened a little lake of
+mountain water. From it the silver thread of a rivulet wormed its
+way for a mile or more among the trees and then trickled over the
+side of the cliff in a vapory waterfall.
+
+Ned had swung the Cibola into a wide curve and the balloon and car
+were soon directly over the mountain creek. He threw the aeroplane
+guides downward and the slowly moving car drifted lower until it was
+but four hundred feet above the water and the overhanging pines.
+Then, following the water course beneath, the air ship floated back
+into the woods and the little lake widened out beneath them. Two
+deer, at the water's edge, stood unalarmed. On the south of the
+lake a grassy opening indicated Ned's destination.
+
+"Here," he explained, "we can make a safe landing. It is an ideal
+place for a camp, with plenty of firewood and water."
+
+"And meat, too," interrupted Alan, pointing to the deer.
+
+"Venison and bear meat too, no doubt," laughed Ned.
+
+From the top of a dead pine tree an eagle rose and soared lazily
+away.
+
+"It's like the camping out places you read about," exclaimed Bob.
+"That eagle nest completes the picture."
+
+"It does," interrupted Ned, "and I hope you won't forget the
+picture. That high, barren tree is your landmark. Some day you may
+need it. Remember; from the valley below your camp can be found by
+locating the little waterfall on the cliff. From the timber line
+above you will know it when you see the eagle's nest. And now let
+go the anchor. We have no gas to spare, and can't afford to open
+the valve."
+
+To make a landing in a balloon without throwing open a valve and
+wasting precious gas is almost impossible. The craft could only be
+kept near the ground by keeping it in motion or by causing the
+propeller fans to depress currents of air on the aeroplanes.
+Therefore, as soon as the engine stopped, the Cibola would mount
+higher. But resourceful Ned had long since thought out this
+problem.
+
+The engine's speed was reduced and the anchor was quickly lowered
+until it caught hard and fast in a strong pine tree. The contact
+shook the fragile car and sent the bag bounding, but when it was
+seen that the iron had fixed itself firmly three of the boys,
+pulling on the anchor rope, gradually drew the great buoyant car
+down until it floated just above the tree top. To drag it lower
+was, impossible, for one sharp branch might injure the bag beyond
+repair.
+
+When the ship was safely anchored just above the tree, the
+twenty-five foot landing ladder was lowered and Ned himself made his
+way down its fragile rungs into the tree. .
+
+"Hold on tight," he continued, "I'm getting off."
+
+As he did so and found footing in the tree branches the Cibola
+tugged to free itself, as if, overjoyed to be rid of Ned's one
+hundred and forty-five pounds of weight. As soon as the young
+commander was safely on the ground he ordered the other boys to pay
+out the anchor rope and again the Cibola rose in the air.
+
+"Now," ordered Ned, "start your engine and head the car over the
+opening."
+
+While Ned stood below directing, with hands to his mouth,
+trumpet-wise, the Cibola strained at her anchor rope and then,
+obeying her rudder, moved directly over the open space, her nose
+pointing skyward at an angle of forty-five degrees.
+
+"Hold her," yelled Ned, "and haul back."
+
+The boys again strained at the taut anchor rope until the car stood
+just clear of the trees and some two hundred feet in the air.
+
+"Now lower your drag rope and an empty ballast bag," called Ned.
+
+While this was being done the navigator of the Cibola was busy
+carrying chunks of broken rock from the margin of the little lake,
+and in a short time the boys above were hauling away on the rope and
+lifting aboard new ballast. With each bag of it the Cibola sank
+lower and lower, until finally, when it was almost balanced in the
+air, Ned easily drew the balloon to the ground.
+
+But the landing was not yet finished. Not a passenger in the craft
+could step ashore until Ned had added more stone. But when enough
+of this had been lifted up to the hands above, and Elmer could
+alight, the two willing workers on the ground soon made it possible
+for the other boys to spring overboard. Then the four of them
+loaded enough more rock on the bridge to take the place of the
+stores to be landed.
+
+There were not many things that could be left: water, and half the
+provisions and, preserved goods; a few cooking utensils; blankets,
+an extra compass, two revolvers, a hatchet and saw; a light silk
+tent; matches and candles, a medicine case, ammunition, and, to make
+way for the gasoline that it was hoped might be recovered, all the
+extra oil on board--for the reservoirs yet contained an ample supply
+to make the trip back to the scene of Elmer's attack.
+
+At a safe distance from the balloon Elmer had returned to his
+favorite occupation. He got a fire going and while the other boys
+replaced the rocks on board with bags of sand from the margin of the
+lake the colored lad made hot coffee and broiled some bacon. It was
+a luxury after the cold, dry food of the long night.
+
+"When you come back this evening," exclaimed Bob jovially, "I'll try
+to have a juicy venison steak."
+
+"An' hot biscuits," chimed in Elmer.
+
+"And a good bed of balsam boughs," added Bob, "and a fine camp fire,
+and we can sit wound it and talk it all over."
+
+"And if we don't get back to-night you'd better have your camp fire
+anyway," said Ned.
+
+"Ain't you goin' to git back to-night?" ruefully interrupted Elmer,
+as he poured the smoking coffee.
+
+"You never know what you are going to do in a balloon," answered Ned.
+"If we can we will. If we can't we won't. If we are not back
+to-night we may not be here for several days. We've got work ahead
+now, and plenty of it."
+
+"We'll be here when you come," replied Bob earnestly, with a smoking
+bit of bacon in his fingers, "whenever that is."
+
+"No," replied Ned, "if we are not here in six days you must make
+your way out to civilization. You have food enough but you can't
+wait longer than that. As for directions, all I can say is that
+from this ridge back of us you can see across the half desert valley
+to the higher range of mountains. Should you cross the valley
+bearing almost due east and be able to get over or through that
+second ridge you will be able to see the top of Mount Wilson, thirty
+miles further east. From Mount Wilson it is fifteen miles southeast
+to the camp Elmer made. There you should pick up the trail of
+Buck's wagon back to the railroad eighty-five miles south."
+
+Bob's eyes opened.
+
+"Is it as bad as that?" he said half laughing. "We'll certainly
+have to get busy if the Cibola breaks down."
+
+"Or," went on Ned, "any strewn in the valley below here flows
+finally into the San Juan River to the north. If you can make your
+way to this river and then succeed in following its banks eastward
+until you reach the plains, some time or other you'll find a
+frontier settlement."
+
+"Or Utes," interrupted Alan.
+
+"Gib me de mountain road," exclaimed Elmer quickly.
+"Nomo'Utesfo'me!"
+
+"Yes," added Ned, "that's the trouble. The route to the San Juan is
+not only through a barren, broken mountain region, but it gets you
+finally right into the Southern Ute reservation. And, remember,
+too, that this is Navajo land. Your safety with them, should you be
+discovered, will be in diplomacy. And now good-bye--until we meet
+again."
+
+"And if we don't," replied Bob, huskily, taking the hands of the two
+boys in turn, "I just want to say again that you boys have done for
+me what I can't forget and what I can't repay. I don't know why you
+are here, and I don't want to know. What I've seen will never be
+revealed, when I get back to Kansas City and the Comet, until you
+tell me I am free to tell it. And you'd know what that means to me
+if you knew what a cracking good yarn my experience has given me
+already. Good-bye and good luck!"
+
+Ned and Alan clambered aboard; the rocks were cast overboard, and as
+the Cibola shot skyward the boys could hear Elmer calling:
+
+"Member, boys--we all'll be at Camp Eagle an' supper will be
+awaitin'."
+
+
+
+
+CHAPTER XXIV
+
+A GRAVE IN THE DESERT
+
+
+But Ned and Alan did not eat with their friends that night, nor for
+some days to come. And when they saw each other again one of
+Elmer's juicy venison steaks would have seemed to all of them the
+sweetest morsel ever eaten by man.
+
+Ned only waited to help inflate the balloonet in the big balloon
+with the little hand blower for the Cibola showed quite perceptibly
+the loss of gas after her twenty hours of inflation. Then, the
+course having been laid, he left the wheel and engine to Alan's care
+and turned in for his long needed rest.
+
+Alan had determined on a record flight. He allowed the Cibola to
+rise higher than it had yet flown, about 5,000 feet, and then
+setting the aeroplanes on a slight incline he headed the car on a
+down slant for Mount Wilson's just visible peak, thirty miles away.
+
+There was no economy in half speed, for time and the utilization of
+their gas were more precious than gasoline. "We can always float
+without gasoline," the boys had said to themselves, "but we can't
+move without gas." Therefore the Cibola was soon at its maximum and
+the enthusiastic Alan knew that Ned would have a short sleep.
+
+In an hour and twenty-one minutes the swift dirigible was abreast of
+the peak of Mount Wilson, and then, without slackening speed, Alan
+altered her course southeast toward the scene of the previous
+night's hair-raising experience. Long before he reached the place
+he was able to make the juncture of the two rivers his landmark, and
+the ship pointed her course as straight as a railroad train. After
+thirty minutes sailing from Mount Wilson, Buck's rendezvous could be
+made out, three miles beyond.
+
+One glance told the whole sad story. Two dead horses alone marked
+the spot where their freight wagon had stood. Alan aroused Ned, and
+as the Cibola sailed low over the place the boys saw that the
+thieving Utes had gone--with the wagon, horses, freight and their
+dead companions.
+
+Poor Buck's body was lying where the brave escort had fallen.
+
+"We can't make two landings," suggested Ned. "We'll find the
+gasoline and then come back and bury our friend."
+
+Disappointed, although they had really in their hearts expected
+nothing less, the young navigators turned the Cibola and sailed
+slowly down the river in the hope that the gasoline would be found
+where Elmer had described it as lying.
+
+They were as richly rewarded here as they had been previously
+disappointed. The drift, a tangled jumble of small mountain wood,
+had caught and preserved seven of their eight tins of gasoline.
+
+It was now noon, and broiling hot, but luncheon was not thought of
+and the difficult work of recovering the heavy packages was begun.
+This presented a new difficulty, for again the boys were determined
+not to lose any gas in making a landing.
+
+The drift was too light to hold their anchor although two trials at
+this were made. Not a bush or tree was to be found nearby. In
+despair at last, Alan was about to suggest opening the valve--for it
+was imperative that they secure the gasoline--when Ned turned the
+bow of the craft down stream.
+
+"Perhaps we can find anchorage further down," he explained.
+
+"But if will be pretty hard work carrying these tins," Alan began.
+
+"They floated where they are, didn't they?" smiled Ned. "What's the
+matter with letting them float a little further?"
+
+His hope was realized. But the solution was fully a mile away. On
+a sandy bar, half buried in the sand, the stout end of a cottonwood
+trunk, the flotsam of some extraordinary freshet, had come into
+view. The experience of the morning was repeated, but on a smaller
+scale, for here were no dangerous tree limbs to threaten their
+delicate silken bag. After two trials and much pulling and hauling
+the car of the Cibola was tied fast to the snag, half over the
+shallow water and half over the sand.
+
+Then, naked as when they were born, and suffering not a little from
+the pitiless sun, the boys started afresh. Alan made his way back
+up the river and began to prod out the stranded tin casks. All were
+soon bobbing along in the slow current, with Alan behind them like a
+lumber driver of the northwest dislodging logs left in the shallows.
+Ned below soon had all of them in shallow water.
+
+By means of a coil of the drag rope, looped in turn about the tins
+of recovered fuel, Ned lifting below and Alan pulling above soon
+transferred the gasoline to the bobbing Cibola. As each cask
+ascended, a portion of the extra ballast was dumped overboard.
+
+Then, dressing themselves and improvising what tools they could, the
+boys made their way sorrowfully to the scene of the previous night's
+tragedy. Buck's body was carefully removed and decently buried. A
+mound of boulders was made over the grave to designate the spot, and
+with the hope that some day they might return and suitably mark the
+desert tomb the boys took a mournful farewell.
+
+
+
+
+CHAPTER XXV
+
+BARTERING STORES A MILE IN THE AIR
+
+
+"And now," said Alan, "it's ho, for Camp Eagle and our search at
+last."
+
+"I don't know about all that sentiment," answered Ned, thoughtfully.
+"I've been--"
+
+But he was interrupted. The boys, aboard the Cibola again, were
+just about to cast off when Alan cut short Ned's remark with an
+exclamation.
+
+"Isn't that a balloon?" he exclaimed pointing to an orange-like
+object high in the heavens toward the west.
+
+Ned caught up the binoculars and had a quick look at the rapidly
+moving ball which was rushing toward them from over the distant
+Tunit Chas Mountains.
+
+"No question about it," answered Ned, handing Alan the glasses; "a
+balloon, and a big one."
+
+"And out here, too!" commented Alan in surprise. "I guess the world
+is pretty small after all."
+
+"Everything ready?" asked Ned eagerly. And then as the retaining
+rope was untied from the frame of the car and slipped down and out
+from under the cottonwood snag the Cibola shot upward.
+
+"I have an idea," continued Ned, "and please don't object until you
+think it over. Let's make a little social call on the stranger!"
+
+"A call!" exclaimed Alan, plainly showing his astonishment; "a call
+on a balloon five thousand feet in the air?"
+
+"Certainly. We are going that high anyway. And we have the means
+of going where we like. If we go up until we strike the same,
+stratum of air the stranger is moving in we have our propeller and
+aeroplanes to check and guide ourselves. When it passes we can
+easily run alongside!"
+
+"Well, if that isn't the limit!" laughed Alan. "And I suppose we'll
+exchange greetings and messages like ships long at sea."
+
+"And," added Ned, "we can send some word to Major Honeywell. You
+can see our fast flying friend isn't going to stop around here."
+
+The Cibola was rising fast and the two air craft were coming closer
+and closer. As the dirigible reached the altitude at which the free
+balloon was sailing Ned put the aeroplane in operation, stopped the
+ascent of the Cibola and then, sweeping his own car into the same
+direction with the other balloon he reversed the propeller and held
+his own craft against the breeze until the stranger swept by.
+
+Then, throwing on the propeller again at full speed, Ned made the
+Cibola bound after the other craft, and in a few minutes, aided by
+the favoring wind, they were within hailing distance.
+
+Ned was on the bridge, his face flushed with the novelty of the
+race. A mile above the earth, the two air ships came closer until,
+as if running on parallel tracks, they were nearly together and
+abreast.
+
+"Balloon ahoy!" exclaimed Ned at last and in true maritime style.
+
+"The Arrow of Los Angeles, bound across the continent," came the
+sharp answer.
+
+"The Cibola from Clarkeville, New Mexico," called Ned in reply,
+"exploring. Please report us over Mount Wilson."
+
+Then the two ships of the sky came closer. The boys could see that
+the Arrow was well equipped for its purpose. Two determined looking
+aeronauts were leaning from the heavily laden car.
+
+"Need anything?" shouted the Arrow cordially.
+
+"In good shape," answered Ned, "but a little short on provisions."
+
+"Plenty here," came quickly from the Arrow, "glad to exchange
+fifty-pound emergency rations for ballast."
+
+"All right," responded Ned, "stand by to make a line fast."
+
+Alan, at the engine, brought the air ship up as skillfully as a
+pilot might a vessel, and as the two cars almost touched Ned passed
+the end of his drag rope, and the occupants of the Arrow with a
+quick turn made her basket fast to the bridge of the Cibola. There
+were handshakes, mutual congratulations and quick explanations. The
+Arrow, the property of a wealthy amateur balloonist, was attempting
+to sail, from the Pacific to the Atlantic and was, so far, beating
+the best calculation of her owner. In reaching the desired height
+that morning, however, much ballast had been used and the
+possibility of a renewed supply was jumped at.
+
+"These extra provisions were packed with the idea of possibly using
+them as ballast and we don't really need them. And, so," they
+explained to the boys, "if you do you had better take them and give
+us sand."
+
+The exchange was quickly made, and then, having stored their new
+food supply safely on the bridge, they said hasty farewells.
+
+Ned had scribbled this note on a page from his note book: "Major
+Baldwin Honeywell, Annex, Chicago. By courtesy of Balloon Arrow.
+Bourke, escort, killed by Indians. Search begins at once. Camp
+established on plateau, second range Tunit Chas Mountains, thirty
+miles due east Wilson's Peak. Greetings. Written 5,600 feet above
+San Juan River, New Mexico. Ned Napier and Alan Hope."
+
+The case of provisions weighed a trifle more than the ballast given
+in exchange, and as the line holding the two cars together was cast
+off the Cibola sank slowly below the level of the Arrow. Then, as
+the Cibola's engines began to push the car ahead in a wide turning
+circle, Ned called up to the disappearing Arrow:
+
+"Great country, this New Mexico, where you can buy food with sand.
+Good-bye and success to you!"
+
+The answer was lost in space as the ships parted.
+
+"And now," said Ned, after lashing the now case of provisions to the
+bridge netting, "we've wasted some more precious time. Do you still
+think we had better lose a night at Camp Eagle? We have all the
+fuel we can carry."
+
+Alan saw what was in the wind.
+
+"We have extra provisions, water and gasoline. My own judgment is
+we had better make at once for our starting point."
+
+"I guess you are right," answered Alan after long thought; "I don't
+know what is to be gained by the trouble of a landing at the camp by
+the lake."
+
+"Nothing but that hot supper," smiled Ned, "and we'll have to put
+that off a few days, I think."
+
+"All right," agreed Alan, "set your course and with luck we'll do a
+little treasure hunting before dark."
+
+This being settled, the prow of the Cibola was pointed a little west
+of northwest, and, dropping to a lower stratum to escape the lively
+eastern breeze at the higher altitude, the boys started at last
+directly for the and arid broken mountains of Northwestern Arizona.
+
+This region, bordering on the great sand dunes lying beyond the
+Chelly River, was to be the beginning point of their arduous and
+momentous search. From that place to a point nearly one hundred
+miles to the southeast lay the secret fastnesses of mountain, canyon
+and mesa wherein, somewhere, according to the Spanish soldier's
+record, was the secret city of a dead race and the treasure that had
+brought Ned and Alan half way across a continent.
+
+What such a search meant one glance at the monotonous and unending
+rock easily told. On foot, only the compass could lead a man
+forward in such wilderness of abrupt heights and winding chasms. As
+the boys meant to manage it, the attempt had possibilities, but it
+might mean days of drifting, of watching, of doubling back and forth
+over every possible site. And that was now their task.
+
+So far as they could, Ned and Alan meant to begin at the extreme
+northern end of this unknown land and, sailing back and forth from
+east to west, cover every foot of exposed ground with their powerful
+glasses.
+
+Both boys had long since agreed in this conclusion: the "city" meant
+no more than one large structure similar to but on a larger scale
+than those found in the Chaco Canyon at the extreme southern end of
+the Tunit Chas Mountains. This would be indicated now by nothing
+more than rectangular lines of wall stones, probably in piles,
+outlining the shape of the "city" or palace. Prominent among these
+ruins should be the more elevated temple, the object of their
+search. And beneath this should be found the underground "khivas"
+or religious chambers.
+
+That this "city" was secret or hidden was proof to Ned and Alan and
+Major Honeywell that it would not occupy a prominent place such as
+an exposed plateau or a high level mesa. Only one other location
+was left, the abutting shelf of some canyon. And the young
+navigators had pictured to themselves that, if this should prove to
+be the location, the shelf would be so elevated as not to be visible
+from the front or below and that it would be concealed from above by
+an extended and overhanging cliff.
+
+"Look for it as you would look for a bird's nest in the cliff,"
+suggested Ned. And that was the plan of search.
+
+It was nearly three o'clock when the boys had bade farewell to the
+Arrow and about half past five when the Cibola sailed over the
+second ridge of the Tunit Chas. But the course was far to the north
+and there was naturally no sign of the waterfall plateau or Camp
+Eagle. For a time they thought of passing over the camp and
+dropping a message, but this pleasant idea was given up.
+
+"Although," as Alan expressed it, "one of Elmer's hot suppers and a
+soft bed of balsam boughs to-night wouldn't be bad."
+
+Ned thought of the four nights of hard floor and agreed, but he
+said:
+
+"You'll have to forget soft beds if we're ever going to find Cibola.
+We'll come down to-night, though, and make a camp of our own with a
+fire and a pot of coffee, and at daybreak we'll be off."
+
+The boys had taken a light luncheon just after starting on the
+return trip, and now, soaring over the Tunit Chas again, they began
+to be anxious for night and supper.
+
+At seven o'clock the peaks and ridges below them had begun to drop
+into foothills and as the great sandy deserts of distant Utah and
+nearer by Arizona came before their eyes the boys decided that it
+was time to anchor for the night. They were sailing over the
+eastern slope of the last low ranges of hills, barren of trees or
+vegetation. The aeroplanes being given the proper depression, the
+Cibola shot earthward and then, the propeller coming to a pause,
+floated gently along above the jumble of rocks. Making fast the
+anchor in a ragged pile of these the boys soon drew the Cibola to
+the ground and lashed her fore and aft to heavy boulders.
+
+The firm ground felt delicious to the tired boys and they refreshed
+themselves with a brisk race over the open space between the rock
+piles. Then came Alan's camp fire, a hot supper and preparations
+for a good night's rest. There were no pine needles of balsam
+boughs, but fatigue made a fine mattress, and it was not long before
+the tired boys, rolled up in their blankets, were fast asleep on the
+soft sand.
+
+"I hope," said Ned drowsily as they were dropping off to sleep,
+"that we won't have any Jack Jellups or thieving Utes to-night. My
+nerves need rest."
+
+Then the boys got eight good hours of health and strength giving
+sleep in the tonic air of the Arizona Mountains.
+
+
+
+
+CHAPTER XXVI
+
+THE SECRET TUNNEL IN THE MESA
+
+
+At five o'clock Ned and Alan were astir. With regrets that they
+were not at Camp Eagle for a plunge in the cool mountain lake, they
+prepared another hot meal, ate it, and boarded the Cibola.
+
+The balloon had now been inflated thirty-eight hours and was
+noticeably showing the loss of its gas. While the top of the bag
+was yet round and firm in the heat of the sun the lower sides had
+become a trifle flabby as the cool evening had come on. Up to this
+time all records for balloon flight had been broken a fact due to
+the renewed buoyancy caused each day by the hot, Southwestern Sun.
+And, exploration in and quick ascent from the canyons before them
+would before long call for the use of ballast. The boys agreed that
+the time had arrived to utilize their liquid hydrogen. The
+shrinkage that night had been quite perceptible.
+
+They regretted that but two-thirds of this remained--about eleven
+cubic feet. This when reconverted meant nearly twelve thousand
+cubic feet of new gas at their present altitude. As the work of
+converting the gas involved care, preparation for it was made before
+the Cibola was cut loose.
+
+The reconverter, a reduced inversion of the apparatus used in making
+liquid air, was made ready. When the muffled explosions and the
+heat of the tubes told the boys that the reconverter was working
+perfectly and pumping new and needed gas into the shrunken Cibola's
+long bag, the lashings were loosed and once more the faithful
+dirigible mounted skyward.
+
+With Major Honeywell's map of the region spread out on the deck of
+the bridge and the binoculars in hand Ned began the long anticipated
+search for the lost city.
+
+All day the process of turning the liquid hydrogen back into buoyant
+gas went on. And all day the Cibola wound her devious course over
+the peaks and chasms beneath. By night half the hydrogen jars were
+empty and Ned and Alan saw the evening close in on them without a
+sign of the object of their search. When darkness stopped further
+work the balloon was brought to earth and camp made again.
+
+The following day, as uneventful as the first, gave no indication of
+the secret city. The rest of the liquid hydrogen was transformed
+into gas. The sun seemed to enfold the craft in a fiery embrace.
+When camp was made again that night the Cibola had been afloat
+eighty hours.
+
+"I think she is good for another forty-eight hours," said Ned that
+night. "If we find nothing in two more days we'll have our choice
+of going out on foot or of quitting in time to pick up Elmer and Bob
+and make a dash to civilization. What do you say?"
+
+"I don't know," replied Alan, "I'd hate to give up as long as we can
+fly. I think the boys can care for themselves. Let's stick to it.
+We have provisions and there is water in some places."
+
+"Well," answered Ned, "we'll have two more days time in which to
+decide."
+
+The next morning the Cibola showed plainly that her gas was rapidly
+escaping. New life was given to the balloon by casting overboard
+some empty hydrogen casks. The fourth day broke hotter than ever.
+In all the wilderness examined by the tired and strained eyes of the
+searchers, not a human being had been seen--not even a wandering
+Navajo. This day they began the search with renewed vigor, but with
+the same monotonous result--miles of hopelessly desert rock and sand
+beneath them, with a little vegetation now and then, but so sign of
+Indian remains.
+
+At noon Ned said:
+
+"If we were not in a balloon with a compass and sextant I should say
+we were lost. And if Indians ever lived and died hereabouts they
+certainly left so signs of their bones."
+
+By six O'clock, with the sun gratefully low, Alan expressed
+discouragement.
+
+"To-morrow at this time," he said, "if we see no indication of the
+old palace or city or whatever it was--if it ever was--I think I'll
+vote to try to find Camp Eagle and get out."
+
+"We'll see to-morrow," answered Ned stoutly.
+
+That night at dark, a landing was made on the ledge of a point of
+land ending in a rounded cliff pointing south, selected because the
+place was open to the breeze and cool. The Cibola had approached
+the height from the west, and the boys believed that the promontory
+projected from yet higher ground beyond. On those portions of the
+cliff that they could see there was neither shelf nor projection of
+any kind. The walls rose almost like cut stone and were apparently
+about three hundred feet high. As the Cibola was about to descend,
+Alan, who was taking a last survey from the bridge, called Ned's
+attention to the fact that even the far side of the supposed
+promontory was separated from the mountains beyond, and that a chasm
+at least a half mile wide separated the two heights.
+
+"It's a mesa," replied Ned with renewed enthusiasm, "and it will be
+a good thing to look over it to-morrow. These high and almost
+unapproachable islands of rock were favorite dwelling places for the
+Indians."
+
+"But a temple up here wouldn't be a secret very long," replied Alan.
+"We've seen this point all afternoon. It's prominent enough."
+
+"That's so," answered Ned, "but we are here, so let's make a landing
+and eat, and dream over it."
+
+The balloon had now lost so much gas that a landing was easy, and,
+tired with four days' profitless search and its strain, the young
+aeronauts were soon beyond even dreams.
+
+It was with no small alarm that the boys saw, when they awoke with
+the first rays of the sun, that the car of the Cibola, which had
+been anchored fore and aft to heaped up rocks during the night, was
+now resting on the ground. Gas, was rapidly escaping. But fortunately
+the aeroplanes and propeller had been left properly in a horizontal
+position and no damage had been done.
+
+The boys knew that by throwing over enough ballast and stores the
+Cibola could be made good for one more flight, but that probably it
+would be the last. Therefore, the inevitable seemed forced upon
+them. They would fortify themselves with a good breakfast, look
+over the mesa, make one more circling flight and then attempt to
+find Camp Eagle. While Alan made haste to prepare breakfast, Ned
+determined first on an examination of the mesa point by daylight.
+
+The rock had a top area of perhaps forty or fifty acres. It had a
+rolling surface and was coated with a carpet of dusty sand, except
+in the northwest corner. The northern end of the mesa, Ned could
+see, widened and ended in a sharp rise almost wall-like in form. At
+the western end this wall-like elevation turned the corner and
+extended south a short distance, finally dropping down to the
+general level of the mesa. In this protected comer grew a strange
+grove of gnarled and twisted pines, ill nourished and apparently
+very old. Between this comer of the mesa and the sharper promontory
+whereon the Cibola had come to anchor, was a wide, sandy, barren
+depression.
+
+The narrow portion of the rocky island where the boys had made camp
+drew in abruptly to make the point that marked the southern end of
+the mesa. Ned turned first toward the point.
+
+When he had advanced, making his way slightly upward all the time,
+to where the narrow mesa was not over four hundred feet wide, the
+lad was astounded to suddenly discover a deep and narrow fissure or
+chasm. It was dark, with sides as abrupt as the cliffs of the mesa,
+and too wide to jump across. A cold air was already rising from the
+opening into the warmer atmosphere above.
+
+In his astonishment Ned called to his chum.
+
+"What surprises me," exclaimed Ned, "is the character of the
+opening. If it extended from cliff to cliff I should say that the
+same freak of nature that made this solitary island of rock also
+split off this end at some time. But it is closed at each end."
+
+Alan hastened to the end of the fissure, near the side of the mesa.
+
+"It looks to me," he said, "as if it had extended entirely across at
+some time and the ends walled up later."
+
+The boys made a closer examination.
+
+"You're right," said Ned when he discovered that each end of the
+rift had been filled with closely fitted rock, "and human hands did
+it."
+
+Alan sprang up in excitement.
+
+"That's the first sign we've had," he exclaimed. "Do you suppose it
+means anything?"
+
+The edge of the cliff was so abrupt that the boys had to lie down to
+look over in safety.
+
+"It does," Ned answered. "The reason you can't see that chasm from
+below or from in front is because the face of it is walled up. And
+it is walled so skillfully that you can't detect it from even a
+short distance."
+
+"That's to hide something," quickly replied Alan, "but I don't see--"
+
+Ned was standing on top of the short filled-in portion of the chasm.
+
+"Look!" he exclaimed, suddenly interrupting his friend. "These
+stones are steps, and, they are worn!"
+
+
+
+
+CHAPTER XXVII
+
+THE TURQUOISE TEMPLE DISCOVERED
+
+
+In another moment he had sprung forward and was quickly descending
+into the narrow, dark pit, with Alan close behind. A cave-like
+smell and a rapidly, cooling air greeted them. They were soon in
+almost complete darkness. When the walls had narrowed to but a few
+feet, a thin ribbon of blue sky was all that could be seen above.
+
+The steps had come to an end. An ascending elevation began just in
+front of them. This they made out by the light of a match, which
+flickered uncertainly in the bad air. Bats dashed against the walls
+and every movement was followed by a cloud of dust.
+
+"Do you feel anything?" suddenly exclaimed Alan. "Seems to me like
+a current of air on my feet."
+
+Ned lit another match.
+
+Before them they again made out an ascending slant such as they had
+come down. But the base of it was hollowed out in the form of a
+small cave. As the light went out both boys stooped to look further
+into this opening.
+
+"Light!" they exclaimed almost together.
+
+They were looking through a tunnel made, as they afterward found, in
+the base of the filled-in portion of the chasm. Reptiles, bats and
+dust were forgotten now. Plunging forward on their hands and knees,
+the two boys advanced without difficulty to the distant mouth of the
+tunnel.
+
+It ended abruptly in the face of the mesa cliff, one hundred feet
+above the valley below. There was not the slightest ledge below it
+and the side of the mesa dropped so precipitately that access to the
+tunnel mouth from without seemed impossible. The possibility of a
+climb to that entrance to reach the mesa above was out of the
+question.
+
+The boys, panting for breath, lay on the floor of the tunnel with
+their heads just out of the opening.
+
+"Some one has used this place, but how did they ever get up here?"
+asked Alan.
+
+"I don't know and I don't care," said Ned with excitement. "But I
+do know that this entrance is concealed. Why, you couldn't even see
+it from below--it's so small. And it was made that way for a
+purpose. That must mean Cibola. Let's get busy."
+
+There were one hundred and thirty-five steps to mount, and each was
+about a foot and a half high. When Ned and Alan were on top of the
+mesa again they were out of breath and their clothes were white with
+dust. They were also choked, thirsty and hungry.
+
+"Eat heartily," laughed Ned, when they began breakfast over again;
+"we are going to have a busy day, I hope."
+
+"What is your theory?"
+
+"That our treasure is right here if it is anywhere," exclaimed Ned.
+
+Alan laughed. "The place is barren as a barn floor," he said; "I
+don't see any very large palace or temple hereabouts."
+
+"I don't either. That's why I'm going to look for it--and look
+hard."
+
+"And our gas slipping away at a lively rate!" interrupted Alan
+again.
+
+"Let it all go," said Ned. "We know how we can get down within a
+hundred feet of the ground, anyway. That's some consolation."'
+
+"First we will make a circuit of the north end," continued Ned,
+after breakfast, "and if nothing comes of that--no unseen hollows or
+new crevices--we'll try this sandy hollow, even if it is smooth as a
+plain."
+
+The circuit of a fifty-acre area requires time and it was an hour
+before the boys had traversed the edge of the precipitous cliff. At
+every few yards they examined the face of the mesa for gaps or shelves,
+but there seemed hardly a resting place for a bird.
+
+Tired and hot, the sun being now high above them, the young
+aeronauts finally reached the north-eastern corner of the mesa
+without finding a sign or suggestion of Indians, or even of animal
+remains.
+
+Alan had thrown himself on the ground at this point for a rest, when
+with an exclamation Ned darted from his side. As Alan's eyes
+followed him he saw the cause of the exclamation. From where they
+stood--directly east from the ancient grove--they could see for the
+first time that the trees stood in a wide double semi-circle, and,
+directly in the center, perhaps fifteen feet in height, arose a
+column of masonry. It was snow white in color and glistened like
+glass.
+
+There was no question about it.
+
+The fabled Temple of Turquoise, its deep blue glaze lost in the
+whitening sun of three centuries, stood before them. Almost
+overcome with the emotion of success the two boys stood as if
+transfixed. Then cautiously, as if afraid the wonderful pile might
+dissolve itself into a dream, they moved forward.
+
+In this protected corner of the mesa where the winds of ages had
+gradually deposited a thin sandy soil, the hand of man had planted
+two almost complete circles of trees. Therein, and generally
+agreeing with the record of the long dead Vasquez, were the plain
+outlines of a stone structure. At places, where the walls crossed,
+and at some of the corners, the masonry yet rose to the height of a
+man. And again, it fell into long irregular piles of jumbled
+blocks. Sifted sand filled each corner and crevice.
+
+In the center of the ruins rose the turquoise column. From this,
+and in a line with the true east to where the boys stood, extended
+an open approach. Almost reverently Ned and Alan advanced up this
+walk.
+
+It was easily seen that the structure had contained a maze of
+rooms--over three hundred, they afterwards discovered--and that the
+white column stood in a hollow square.
+
+"It's white," almost whispered Alan.
+
+"Yes," answered Ned; "it ought to be blue."
+
+They were now at the foot of the column. Directly in front stood an
+opening or door. Bordering this was a framework of brick-like
+squares or tiles, black, and ornamented with white figures.
+
+"Just like pottery," said Alan, noticing the true geometrical design
+and the still cruder outlines of animals.
+
+"Look," exclaimed Ned, pointing to the top of the door.
+
+Here, the small tiles were replaced with a large square of black
+tile, in the center of which shone a dull yellow radiating design.
+
+"A symbol of the sun," explained Alan, "and of gold!" he added
+excitedly.
+
+"Then it certainly is our secret city," said Ned.
+
+As he said this he was busy with his knife, digging at the
+glistening white bits with which the column was coated. Finally one
+came off. It fell into his hand and the back of it came into view.
+
+The two boys broke out in an exclamation of delight. The protected
+portion of the piece was a deep sky blue.
+
+"The Turquoise Temple!" they both cried together. "Hurrah!"
+
+When night came again Ned and Alan were almost too excited for rest
+or sleep. Nor did they taste food again until the dust of the ruins
+warned them temporarily to abandon their search. To walk into a
+treasure house that the daring adventurers of two races had
+overlooked for three hundred years was enough to turn the heads of
+any two boys.
+
+The "Doorway of the Sun" as Alan called it, led into a chamber about
+fifteen feet square. The walls of this were lined with smooth clay
+squares of black tile, undecorated. Eight feet above the floor,
+which was also of clay tile and half buried under sand, rose a
+ceiling of arched stones. There was no opening in this, but steps
+on the outside of the temple and in the rear led to a chamber above,
+in the front of which, and also facing the sun, was another opening
+about two feet from the floor. In front of this window was a stone
+bench or altar. The meaning of it the boys did not know. This room
+was barren of either decoration or utensil and it was half full of
+the debris of what had apparently been another arched stone roof.
+Only the front or eastern side of the structure was coated with the
+precious turquoise; the other sides of the column were of plain,
+fairly well fitted, mortarless stone blocks.
+
+
+
+
+CHAPTER XXVIII
+
+THE COLLAPSE OF THE CIBOLA
+
+
+An opening in the paved court in the rear of the Temple, half filled
+with drifted sand, led into a "khiva" or secret religious council
+chamber beneath. Herein the young adventurers discovered their
+wonderland and the reward for all their labors.
+
+Hastily returning to the balloon, they procured candles and
+improvised scoops out of the sides of the tin emergency ration case
+obtained from the Arrow. Major Honeywell had warned the boys that
+the floors of all closed chambers of this sort were covered with the
+accumulated dust of ages.
+
+The first examination of the "khiva" resulted in disappointment.
+The immediate impression that the boys received was one of cave-like
+barrenness. In the half-light only a gray monotony met the eye.
+Yet under this ghostlike pall, forms soon began to appear. In the
+center of the chamber stood what was apparently an altar. In spite
+of its burden of dust an elevation could be seen about eight inches
+high and seven feet in diameter, on which was a boxlike structure
+about three feet square and four feet high. On top of this was a
+dust-covered figure. Beyond, in the deepest gloom, the mouths of
+four radiating tunnels leading still further into the ground could
+be seen. The roof was supported by irregular round columns,
+apparently of wood, arranged in two circles.
+
+Before beginning an exploration of the chamber the boys decided to
+ascertain the depth of the dust covering the floor, into which they
+had already sunk over their shoe tops. This was stifling work, for
+the soft powder ran back as fast as it was dug away. A half hour at
+least was consumed in reaching the bard surface beneath. The
+coating of dust was nearly three feet deep.
+
+As Ned climbed out of the little excavation Alan held the candle
+down. To the astonishment of the boys a beautiful blue sheen met
+their gaze.
+
+"Turquoise flooring!" shouted Ned.
+
+It was true. The entire "khiva," so far as the boys subsequently
+uncovered its floor, was a crude mosaic of the most perfect
+turquoise, the pieces, varying in size, being laid in a lime-like
+cement.
+
+A general survey of the room and its connecting tunnels showed that
+each radiating arm led, with about twenty feet of passageway, into a
+smaller room. In each of these rooms were nine column placed in a
+rectangle. The main chamber was circular in form, forty-eight feet
+in diameter, and the smaller apartments were twenty-four feet
+square.
+
+Ned while at work examining the floor, suddenly ceased and rushed to
+one of the columns.
+
+"You remember," he exclaimed, "the Spaniard said these columns were
+of gold and silver."
+
+But in this the ancient record was wrong. The inner six supports
+were painted a faded yellow and the second row, twelve in number,
+was colored red, as the boys discovered later when they brushed and
+cleaned some of them. Around each of the inner columns, however,
+there were two metal bands about two inches wide and thirty inches
+apart. The lower ones were six feet from the floor. They were of
+heavy gold with loops or hooks extending from each side, as if
+festoons or connecting bands had once extended from pillar to
+pillar.
+
+"Not a bad substitute!" exclaimed Ned.
+
+The second line of twelve columns had similar rings of silver, as
+the boys discovered in good time. The movable contents of the room
+were not easily examined, as each object on the floor was buried
+under a mound of heavy, suffocating dust. Bats had made the place
+an undisturbed refuge, and the repulsive flutter of these creatures
+was disconcerting.
+
+A preliminary examination of the four lateral passages and the rooms
+at their far end showed that these were probably store rooms,
+excepting the one on the east side. Here, on shelves, fixed on
+columns or posts similar to the colored supports in the principal
+chamber, were eight oblong forms. Even the dust and refuse could
+not disguise the nature of these--they were unmistakably mummies,
+the embalmed bodies of either chiefs or priests. At the head and
+foot of each were various dust covered receptacles and utensils.
+
+The afternoon was too short for the boys to accomplish the removal
+of anything.
+
+"I feel like a grave robber," panted Alan, soberly, as the two boys
+clambered out into the fresh air, finding, to their surprise, that
+it was already night.
+
+"Well, I don't," said Ned. "These things are so old that they seem
+to belong to Time itself. I feel more like a gold miner who has at
+last struck a rich vein--and it's our vein."
+
+But, as so often happens, ill luck came close on good fortune. The
+first glance of the young aeronauts at the camp and the Cibola was
+enough to chill their new happiness. The big gas bag had settled so
+low that it half concealed the car, which was resting flat on the
+ground. The buoyancy of the air ship was gone. Without more gas
+the Cibola could not make another flight. It was a severe blow to
+Ned and Alan; but they met the issue squarely.
+
+"There is no use in worrying," said Ned, finally, when they realized
+the exact situation, "and we've got to make the best of it.
+Besides," he said, laughing, "we are not ready to go."
+
+"That's right," replied Alan, thinking of the yet unexamined
+contents of the Treasure Temple, "and when we are ready I guess
+we'll be no worse off than Bob and Elmer. I suppose we can manage
+the one hundred foot descent some way."
+
+Ned pointed to the hundreds of yards of net cordage.
+
+"Right," exclaimed Alan, "that'll be easy--a rope ladder."
+
+It was almost dark and the boys were covered with the penetrating
+grime of the long undisturbed "khiva." A meager wash up and supper
+and rest were in order. But Ned said:
+
+"By morning the Cibola will be in collapse. It is a valuable
+machine, and it ought not be left out here on this point unprotected
+from the seasons. We shall probably never see it again, but while
+we can move it let's tow it over in front of the temple and put the
+bag and engine and instruments in the protected room."
+
+It was not a difficult task. With no great effort the car was half
+carried and half dragged down the slope and then to the clearing in
+the pine grove where the boys soon made a new camp. To complete
+their work the big bag of the balloon was untied from the car and
+drawn, half inflated, into the pathway leading to the temple door.
+Then, with no small regret, the boys opened the escape valve, and in
+a few minutes the collapsed Cibola was stretched like the cast off
+skin of a snake along the sandy pathway, ready to be rolled up and
+compactly stored away.
+
+
+
+
+CHAPTER XXIX
+
+THE GOLDEN EAGLE OF THE AZTECS
+
+
+In the morning the boys went at their task with renewed vigor.
+Inventory was first taken of the stores and provisions. There was
+enough food for about six days, if used with care. Of water there
+was a supply apparently for a little longer period. But the choking
+dust of the "khiva" made bathing almost a necessity, and, used in
+this way, even sparingly, the supply would not last over two days.
+
+"No more baths until we go down into the valley," ordered Ned.
+"Cleanliness would be a comfort, but we'll have to be uncomfortable."
+
+Permanent camp was made in the cabin of the dirigible. In arranging
+this all the machinery, the engine, the blower, the dynamo, the
+reconverter and the aeroplanes, the rudder and the propeller were
+unmounted, and the smaller articles made ready for storing in the
+temple entrance. There were four casks of gasoline left unused. As
+these were being carried to the temple Ned suddenly exclaimed:
+
+"Why not rig up the engine and dynamo and use an electric light down
+in our cave of Mystery."
+
+"Good," answered Alan, "and while we are at it, why not hook up the
+balloonet blower with the engine and get fresh air?"
+
+The stowing away of the machinery, the packing of the gas bag and
+the setting up of the engine and dynamo and blower afforded plenty
+of work until noon; and then, while the trusty little engine was
+pumping volumes of good sweet air into the hot, almost suffocating
+chamber below ground, the boys had luncheon.
+
+Then began the real exhumation of the long buried articles in the
+secret religious chamber of the almost forgotten race. As
+revelation succeeded revelation in the next two days the paralyzing
+wonder that first came to Ned and Alan was succeeded by the dullness
+of fatigue. At intervals of not more than an hour they came above
+ground for fresh air. The absence of water soon converted them into
+bronze-like human statues. They could feel that their lungs were
+becoming clogged with the almost impalpable dust. But they
+persevered. The prize was too rich to be abandoned because of mere
+physical discomfort.
+
+By means of the wired drag rope the powerful incandescent light was
+carried to all the chambers. And one after another, as the blower
+gave the boys air and helped sweep away the clouds of dust, the
+remains which had lain buried for over three centuries were
+uncovered and brought above ground.
+
+Of the pottery itself, vases, jars, and religious ceremonial
+utensils, perfect in shape and displaying ornamentation that would
+have delighted Major Honeywell, the excavators could take little
+note. After removing the twelve gold hoops or bands from the
+supporting columns and twenty similar silver rings from the second
+row of pillars, the boys penetrated the elevation in the center of
+the "khiva."
+
+As the end of the blower pipe was directed against this square
+column, the sediment of centuries disappeared. Then the brilliantly
+penetrating glare of the reflected electric light fell on the
+elevation and both boys burst out in an exclamation of amazement.
+
+
+On what had been a ceremonial dais stood the treasure of the secret
+city of Cibola--an image of the sacred Golden Eagle of the Aztecs.
+The revered bird of the Aztecs stood upright, its extended head
+peering east. The body of this aboriginal work of art, crude in
+form, was of massive silver. And to it were attached overlapping
+plates of gold in the similitude of feathers. The unfolded wings
+were also of gold. The head, beak and talons were of gold, and the
+eyes were two polished bits of quartz. The idol, for such no doubt
+it was, stood forty inches in height and weighed about three hundred
+pounds.
+
+The base on which the precious eagle stood was completely covered
+with the deepest blue turquoise. At its foot and covering the dais
+were the crumbled traces of many articles of cloth, feathers, bits
+of wood and pottery, and the like, all, no doubt, fragments of
+priestly utensils of worship. The most ornate and best preserved of
+these was a large flat bowl covered on the inside with skillfully
+cut mother-of-pearl. This was still iridescently beautiful, and the
+more striking because its milk white exterior was unmarked by
+decoration.
+
+Each mummy, when hauled into the open air and examined, gave more
+positive proof of the riches that had been collected in this sacred
+retreat. The funeral bowls placed at the feet of the bodies varied
+in form and material. Some of these were of plain black and white
+pottery, others were coated with gold, silver, or mother-of-pearl.
+The bowls apparently had once contained food. In all there were
+two golden bowls, four of silver, one of pearl and one of pottery.
+
+Each mummy was wound with as much care as was ever bestowed on the
+Egyptian royal dead. The woven wrappings were coated with pitch and
+beneath them were colored cotton cloths, affording proof of a high
+civilization. The richest treasures of the dead were the
+breastplates and necklaces found on each. These astounded the young
+investigators.
+
+These plates and beads had been strung on deer sinews, which, not
+having been protected by pitch, were now only lines of dust. But,
+lying on the breast of each there was invariably a "body scraper,"
+(as Major Honeywell afterwards termed them) of gold, silver or
+mother-of-pearl. Mother-of-pearl discs were the commonest neck
+decoration. Of these the boys discovered four.
+
+On three of the bodies were pierced pearl bead necklaces. On the
+most elaborately wrapped figure, that of a head priest or high
+chief, came the crowning discovery. This was a necklace of pierced
+amethysts. And on the breast of this figure was a flat plate of
+gold with sixteen radiating points, each of these terminating in a
+large luminous unpierced and polished amethyst.
+
+About the waist of this shriveled figure were the remains of a
+jeweled belt. The foundation or back of this had dissolved into
+dust, but careful unwrapping of the cerements revealed the priceless
+ornamentation. This decoration was of alternating squares of
+mother-of-pearl, in each of which glistened a perfect amethyst, and
+of matchless turquoise squares set with great pearls.
+
+
+
+
+CHAPTER XXX
+
+A QUARTER OF A TON OF TREASURE
+
+
+It was impossible for the boys even to venture an estimate on the
+value of the immense mine of turquoise, although they realized that
+the increasing scarcity of the jewel made the beautiful and unique
+specimens everywhere about them worth a great deal of money. Nor
+had they any idea of the value of the mother-of-pearl bowls, nor of
+the hundreds of beautiful and unique ceremonial and funeral urns and
+vases. Least of all, could they put even an approximate price on
+the amethyst and pearl necklaces. Even their most sanguine hopes of
+discovering the hidden city of Cibola had not led the adventurers to
+investigate the current prices of precious stones.
+
+Knowing, however, what the prices of gold and silver were, they
+could form some estimate of the worth of this part of the treasure.
+
+By comparison with the known weights of certain articles in the car
+the two boys made the following list of metal pieces discovered:
+
+ GOLD POUNDS
+
+ Twelve bands. Weight each 2 lbs. 1 oz. 26
+ Two bowls. Weight each 6 lbs 12
+ Two "body-scrapers." Weight each 9 oz 1 1/2
+ Wings, head and talons of Sacred Eagle 82
+ Breastplate 3
+ Radiating sun over entrance 12
+
+ Total, 136 1/2, or 1,638 ounces.
+
+ SILVER POUNDS
+
+ Twenty-four bands. Weight each 1 lb. 8 oz 40
+ Four bowls. Weight each 5 lbs 20
+ Four "body-scrapers." Weight 10 oz.. 3 1/3
+ Body of Sacred Eagle. Weight 218
+ Ninety-six miscellaneous rings, bands,
+ anklets and wristlets, many set with
+ mother-of-pearl and turquoise 16 1/3
+
+ Total, 297 2/3, or 3,580 ounces.
+
+
+The market value of these precious metals was easily computed. The
+silver at sixty cents an ounce was worth $2,148. The more valuable
+gold, at twenty dollars an ounce, was worth $32,760. Together, the
+484 pounds were worth $34,908.
+
+"And one-third of that," said Ned with a smile--almost discernible
+beneath his dust--begrimed face, "is nearly $12,000. And that is
+$6,000 for each of us."
+
+"But how about the amethysts and pearls?" said Alan.
+
+"I suppose," answered Ned, "that they are worth a great deal more,
+but I don't know. I should think that those that have no holes in
+them would be very valuable."
+
+All this figuring was intensely interesting, but the boys, as the
+revelation progressed, knew that they were now facing a new problem.
+They could not possibly carry that gold and silver, to say nothing
+of even a portion of the exquisite mother-of-pearl bowls or the
+finest samples of the turquoise. When, in the end, nearly a quarter
+of a ton of the metal treasure alone lay in a heap in the corner of
+the temple vestibule they could come to but one conclusion.
+
+This portion of the treasure would have to be removed at another
+time.
+
+"It has lain here undisturbed for over three hundred years," said
+Ned hopefully, though sadly, "and we'll have to take a chance that
+it can be left a while longer."
+
+Sorrowfully enough Alan agreed. It was to be no easy work getting
+out of the wilderness, and food must be carried. That might be more
+precious to them than gold before they saw a railroad again. The
+boys agreed to take at noon the next day the exact latitude and
+longitude of the mesa. The latitude, on one slip of paper, was to
+be carried by one boy and the longitude, on another piece, was to be
+in the possession of the other. This was a precaution against
+accidental revelation of the treasure mesa.
+
+The set jewels were removed. There were two hundred and ninety-four
+pierced pearls and ninety-eight pierced amethysts. Among the whole
+gems, eighteen magnificent pearls were extracted from the jeweled
+belt. Eighteen unpierced amethysts were also taken from the
+alternating turquoise squares of the belt and sixteen magnificent
+amethysts from the gold breastplate.
+
+It was then that the sewing kit supplied by Alan's sister Mary came
+into service. A small piece of aluminum waterproof silk cabin
+covering was converted into two flat bags and in these the stones,
+equally divided, were enclosed and concealed under the clothing and
+beneath the right arm of each lad. In addition, each boy took half
+of the mother-of-pearl and turquoise belt plates as the finest
+specimens of each material.
+
+"And to show that there is gold too," suggested Alan, "we might as
+well take along, these gold 'scrapers,' which won't bother us much,"
+So these two pieces were strung on cords and suspended about the
+necks of the young treasure seekers.
+
+"And to-morrow," exclaimed Ned joyfully when all this was done,
+"we'll get down from here and get a bath."
+
+"Amen," added Alan earnestly.
+
+Until it was twelve o'clock, the time to take their observation, the
+boys spent the next morning in last preparations and making
+everything shipshape. The framework of the car was left intact, but
+weighted by stones to prevent injury by the wind. Everything
+movable was stored in the entrance room of the temple, including
+three and one-half cans of gasoline. The engine was oiled and
+covered with blankets. Underneath the smoothly folded balloon, in
+the folds of which dry sand had been liberally sprinkled to prevent
+possible adhesions of the varnish, lay nearly thirty-five thousand
+dollars' worth of curiously wrought gold and silver. This was first
+completely covered with sand.
+
+The two provision packs for the retreat to civilization had been
+carefully arranged. How long the journey might take they could not
+estimate. They had decided to their way east, in hope of falling in
+with Elmer and Bob, and this meant the crossing of at least two
+mountain ranges and thirty miles of barren foothills to Mount
+Wilson. Then, if they turned south, they would traverse eighty-five
+miles of sandy plain in which water was infrequent.
+
+Their own provisions were exhausted. What they now depended on was
+the emergency case secured from the Arrow. This supply was intended
+to be enough for two men for two weeks.
+
+"It certainly ought not take us that long,"' complained Alan. "Why
+not leave half the supply and take a little gold?"
+
+But Ned was obdurate. He explained that they might fall in with the
+other boys, and that if they did Elmer and Bob might be wholly out
+of supplies.
+
+"We can come back if we get out in good shape," explained Ned, "and
+if we don't get out what'll be the use of a back load of gold?"
+
+That settled it. The food packs were made up of the following
+supplies: Flour, 12 lbs; corn meal, 5 lbs; beans, 5 lbs; bacon, 7 1/2
+lbs; rice, 5 lbs; oatmeal, 2 lbs; baking powder, 1/2 lb; coffee, I
+lb; tea, 1/2 lb; sugar, 5 lbs; lard, 2 1/2 lbs; salt, 1/2 lb; pepper,
+1/8 lb. Each provision pack weighed twenty-one pounds. In addition
+there was an aluminum frying pan, a coffee pot and two aluminum
+plates. A water canteen, a blanket, a revolver and belt of
+ammunition and a knife apiece completed the equipment. Alan carried
+in addition the "snake bite" case, the compass and small hatchet,
+and Ned the money belt containing over five hundred dollars in gold.
+
+The sealed glass tubes of matches were divided between the two boys
+and then, as it was noon, the sextant that Ned had been so careful
+to bring with them was used for the first and last time. The
+observation made and noted, and the record of it divided as planned,
+Ned and Alan were ready to begin their attempt to make their way out
+of the rock-bound wilderness. With provisions, water, blanket and
+arms each lad was carrying about thirty-five pounds.
+
+"Would you still like a few pounds of Aztec treasure?" laughed Ned
+as they stood with packs adjusted.
+
+"I should say not," retorted Alan; "I'm satisfied."
+
+The method of lowering themselves from the hole in the face of the
+cliff to the ground, one hundred feet beneath, had been worked out
+in detail and the apparatus made in the evenings by the light of
+their camp fire. And early that morning Alan had carried the long
+rope ladder down the chasm and to the mouth of the tunnel. Now, in
+addition to their packs, the two boys carried between them a section
+of one of the pine trees, about six feet long.
+
+As they stood, ready to leave, Ned raised his cap.
+
+"Good bye, old Cibola," he said with moisture in his eyes, "until we
+meet again, if ever."
+
+"If ever?" added Alan quickly with as much gaiety as he could
+summon. "You don't think we'll ever let anyone else lift that
+little pile?" and he pointed to the well filled entrance room of the
+temple.
+
+"No," answered Ned, soberly, "if we have as good luck on the land as
+we had in the air."
+
+Ned and Alan meant to reach the earth by means of a rope ladder.
+This they had constructed from the stout Italian hemp suspension
+cords of the Cibola. These ropes, each thirty feet in length, were
+knotted and then doubled to insure strength. For the last
+twenty-five feet at the bottom the landing ladder of the balloon was
+used. The rungs, two feet apart, were of pine from a felled tree,
+and were thirty-eight in number.
+
+For anchorage, the six-foot length of tree was dragged to the mouth
+of the tunnel and, five feet from the opening, wedged between the
+floor and roof of the tunnel, slightly inclined forward. The strain
+on the bottom would thus only fix the supporting section more firmly
+in place. From the bottom of the pine shaft a loop of four of the
+suspension cords reached just out of the tunnel opening. To this
+loop the top rang of the ladder was tied, with a separate
+hundred-foot length of cord. After the ladder had been made firm
+with a running slip knot the hundred-foot length of cord was dropped
+to the ground.
+
+This arrangement had been provided in order that the rope ladder
+might be removed after the descent. By a jerk of the cord the slip
+knot would be loosened and the ladder, released, would fall of its
+own weight. Another length of rope had been prepared, this one
+somewhat over a hundred feet long and also doubled for strength.
+This was for the lowering of the packs and other articles by one of
+the boys after the other had descended. To insure its free running
+and to prevent its wearing through on the edge of the cliff, a six
+inch section of the pine tree had been prepared, flattened on one
+side and having a wide smooth groove in the top. This, attached to
+a short length of rope, which was made fast with the ladder loop to
+the upright shaft in the tunnel, was fixed on the verge of the
+opening.
+
+Finally everything had been arranged and made fast. Each of the two
+boys insisted that he should go down first. To solve the dispute,
+they cast lots and the risk of testing the rope fell to Ned.
+Slipping off his shoes and socks, which he hung about his neck, he
+sprang to the ladder. Alan hung over the edge and watched him with
+apprehension, but Ned, feeling his way carefully, was soon on the
+ground.
+
+His shout was the signal to begin the work of lowering the packs.
+And down they came, one after another; provisions, revolvers,
+blankets, water bottles, and even the money belt, for Ned had made
+himself as light as possible for his descent.
+
+At last it was Alan's turn. The last load had descended, the
+lowering line had been released, drawn up and stowed away. The slip
+knot was examined anew and then Alan followed Ned down the slender,
+fragile swaying rope ladder. When he had reached the ground by
+Ned's side and the strain was over, the boys shook hands jubilantly.
+
+"--And now," shouted Ned with a laugh, "last chance! If you want to
+go back for a new load say so before it is too late."
+
+Alan, exhausted with the climb, shook his head.
+
+"Then stand from under," cried Ned.
+
+As he jerked the slip knot cord the boys sprang aside and the long
+ladder, wriggling, crashed at their feet.
+
+The only means of reaching the towering elevation had been removed
+and the only visible sign of their brief occupancy of the secret
+mesa had been destroyed.
+
+
+
+
+CHAPTER XXXI
+
+AN ADVENTURE WITH THE NAVAJOS
+
+
+Three days later, Ned Napier and Alan Hope, worn and almost
+exhausted with the steady climb and descent of countless rocky
+heights, made their camp for the night at the foot of a rugged
+slope. Their shoes were torn so that a protection of rags was
+necessary. The hot and pitiless sun had seemingly dried up their
+boyish spirits. Silent with fatigue, having plodded steadily
+forward since sunrise, they threw themselves on the sand.
+
+The young adventurers were headed straight for the east. And still
+the last range of mountains was beyond them. Led by the compass,
+they held to their course, sometimes passing miles out of their path
+to avoid some inaccessible mesa, but more often scaling ragged and
+tiresome heights.
+
+Eating had now become a matter of form and necessity. There was no
+longer the keen joy in making camp. During the three days the boys
+had seen no living object except birds, rabbits, many deer and two
+bears, all of which they had left unmolested in their eagerness to
+press forward. But at noon on this day Alan, having occasion to
+glance backwards, was positive that he saw a human head. Whether
+white man or Indian he could not determine. The incident gave the
+lads no little, concern, but as no further sign of a human being was
+seen that day they finally forgot the matter.
+
+That night, after making tea and taking a little more pains than
+usual with their supper in an effort to revive their spirits as well
+as their tired bodies, Ned and Alan spread their blankets at the
+edge of a pine grove. Almost before it was dark they were both
+sound asleep.
+
+Some hours later Alan awoke with the instant consciousness of an
+unusual sound. Motionless and straining his ears, he heard deep
+breathing just behind him. A new moon was just sinking below the
+buttes on the far side of the little valley in which they had
+stopped for rest, but under the pines the shadows were deep. He
+knew that danger was near and he did not move. In another moment he
+felt a soft hand on his waist, as swift and as silent as a snake,
+and he knew that the hand was extracting his revolver.
+
+Then, from his half-opened eyes, he saw a figure crouching over his
+chum just opposite. Some one no doubt was also removing Ned's
+weapon. Then there was the pressure of stealthy footsteps on the
+pine needles and Alan moved his head until he could see two
+indistinct forms moving from the shadows of the timber across the
+open space to the dying embers of their little fire. There he could
+easily discern five or six figures. He was about to put his hand on
+Ned's face to awaken him gently when he saw the entire group coming
+directly toward their sleeping place. Their movements now revealed
+plainly that they were Indians.
+
+With cold beads of perspiration covering his body Alan again
+pretended sleep. It was now apparent that they had been followed,
+and, no doubt, by Navajos. Perhaps this was the end of their
+toilsome retreat. With visions of death presenting themselves, he
+wondered again whether he ought to arouse Ned. Then he realized the
+futility of such action. As the moccasined feet drew near Alan
+could read death in each approaching sound. But at the edge of the
+trees there was another pause, and then he knew that the Indians had
+scattered.
+
+Straining every muscle in an effort to breathe naturally, like one
+asleep, the boy counted the seconds while he waited for the clutch
+of a savage hand. And as the moment passed and the attack did not
+come he tried to speculate on what the strangers were doing. A
+guttural half exclamation soon allowed him a quick breath of
+temporary relief. The Indians were only after their supplies.
+
+The savages had found the half-concealed packs of the two boys.
+Alan knew this by the location of the sounds that now came to him,
+and then, as the prowlers withdrew again into the open and the faint
+moonlight, it could be seen that they were bearing all the
+belongings of the two lads. For perhaps ten minutes Alan lay
+without moving and watched the Indians. He could make out that they
+were hastily looking over the packs and dividing what yet remained
+among themselves. Then ponies were led to the place of the camp
+fire and the members of the band quickly threw themselves on their
+animals and disappeared into the night.
+
+Almost paralyzed with the knowledge of what this meant Alan now
+softly put his hand on Ned's face:
+
+"Are you awake?" came instantly from Ned.
+
+"Are you?" retorted Alan in surprise.
+
+"Yes," whispered Ned, "I saw it all. But I didn't move, because I
+was afraid of arousing you."
+
+"Here, too," exclaimed Alan. "Did you feel them take your
+revolver?"
+
+Ned's band flew to his belt.
+
+"Is yours gone too? I saw them when they came up from the fire.
+But you did right to keep still. If we had moved I expect we'd have
+had our throats cut."
+
+"That was one of them I saw to-day," added Alan, "and I guess we're
+lucky to be alive."
+
+"Yes," added Ned rising to his feet, "we are. They are satisfied, I
+suppose, to let us starve."
+
+The prospect was a trying one. If the range behind them was the one
+they hoped it was, there was only one more valley between its summit
+and the outer ridge of the Tunit Chas. If they could reach this
+ridge they believed they might see Mount Wilson's peak. But even
+that meant another thirty miles to the scene of the attack on Buck's
+camp on the banks of the Chusco. And from that place it was
+eighty-five miles to a railroad and help!
+
+The boys sat in the edge of the pines as the new moon disappeared,
+leaving them in utter darkness, and tried desperately to encourage
+each other. Both had the grit to set themselves stoutly to the
+apparently hopeless task. Without food or firearms and possibly
+without water, they knew they would find the task gigantic. But
+nothing was to be gained by waiting for starvation and death in the
+wilderness, and their decision was to do what they could, to try the
+almost impossible, and if they failed to fail with their faces
+toward the east.
+
+"Why not start now?" urged Alan. "Let's use what strength we have."
+
+But Ned showed him the folly of this.
+
+"A night's rest will enable us to make better time to-morrow. And
+besides, we can't make headway when we can't follow the compass."
+
+Retiring a little further into the woods the boys composed
+themselves again and before long were once more fast asleep.
+
+
+
+
+CHAPTER XXXII
+
+ALAN SUCCUMBS TO EXHAUSTION
+
+
+The boys were up at dawn. Not an article had the marauders left but
+the two water canteens which had fortunately been left hanging from
+the low branches of a pine. It was useless to look for more--there
+was nothing more to be found.
+
+"Anyway," laughed Ned, "it leaves us in light marching order and we
+can make better time. I'm glad we had a good supper."
+
+As no breakfast was in sight the two boys filled the water bottles
+at the creek in the valley, and at five o'clock, taking their
+bearings due east, Ned and Alan struck upwards through the pine
+woods. It was a not unpleasant climb while the boys were fresh, but
+as the slope grew more precipitous the work began to tell. At one
+o'clock the crest was reached.
+
+"How would you like a piece of broiled bacon, some pancakes and a
+cup of coffee, Ned?" asked Alan as they paused to rest.
+
+"In the middle of the day and on the top of a mountain I always
+prefer plain water," laughed Ned in reply. "Here's to you!"
+
+With a big drink from the lukewarm canteens the boys did not pause
+long.
+
+"To-night," continued Ned, "we ought to sleep high up in the
+foothills over there."
+
+With that inspiration the sore-footed and jaded lads made good time
+going down the slope. Then another rivulet was encountered, in
+which they bathed and by which they rested a spell. Alan would have
+been glad to pass the night here, but Ned urged him on, and as night
+fell again the hungry, exhausted boys found themselves far up on the
+new slope. Then they slept again, restlessly and on the rocky
+ground, for they had abandoned their blankets.
+
+The boys did not wait for daylight. In the half dawn they were
+afoot.
+
+"Take another hitch in your belt, chum, and don't think of the
+Placida." laughed Ned. "We'll make it all right, somehow."
+
+Stiff in limb, their feet twitching with the pain of blisters, Ned
+and Alan toiled slowly through the last of the pines and out into
+the rocky higher slopes of the range. It was like climbing an
+upright wall, Alan said, but the pain of going on was less than the
+despair of giving up. A little after six o'clock Ned, ahead, pulled
+himself breathless to the highest point.
+
+Alan stopped a little below and waited in anxiety. Before he could
+ask whether it was the last ridge, Ned's voice broke out into a
+shout.
+
+"Come on, old man, we're all right. There's old Wilson, the
+grandest mountain peak in the world. Hurrah for Mount Wilson!"
+
+But there was no echo to his exclamation. Poor Alan, succumbing to
+pain and exhaustion, had sunk insensible to the ground. In another
+moment Ned was at his chum's side. Forcing some water between
+Alan's lips and bathing his face with some more of the precious
+liquid, Ned soon brought him back to consciousness. Alan sprang up
+in chagrin, and with tears in his eyes insisted that he had only
+stumbled and fallen. But Ned knew the truth. His friend's bright
+eyes and feverish skin told that his condition was grave.
+
+The unseen tears came to Ned's eyes, for it was at least thirty
+miles to more water and the plains. And should they even reach the
+Chusco, he could see only death in the desert.
+
+"You'll feel better in the cool of the woods down there," said Ned
+gently, "and maybe we can kill a rabbit. Hurrah, come on, Alan!
+Brace up. It's all down hill, now. Here's for the woods and
+broiled rabbit!"
+
+In a new spurt of life another start was made and the two chums set
+out down the slope. In one of Ned's hands was a rock. It was to be
+the death warrant of any small animal, and his eyes were busy
+examining each sheltered rocky nook and bush. Suddenly a feverish
+hand caught his.
+
+"Look," whispered Alan.
+
+Ned's eyes followed his chum's gaze.
+
+It was a spiral of thin smoke in the trees below.
+
+With a shout, Ned sprang forward. Then he turned. Alan was
+standing still. Ned's heart grew cold:
+
+"See the smoke," Alan was repeating, "see the nice smoke. Maybe
+it's a house on fire."
+
+His friend was delirious. Ned flew to his side once more and again
+his touch revived the exhausted boy. Almost five days of wandering
+and the exhausting toil on the mesa had proved too much for the more
+delicate Alan, and Ned realized with sickening horror that the
+situation was critical.
+
+"I'm all right, Ned," answered Alan when his chum was once more with
+him; "just a little lightheaded. But that's all."
+
+What was to be done? The smoke might be that of a forest fire. And
+it might mean Indians. But even an enemy is welcome when starvation
+and death confronts one. Almost at the end of his own resources,
+the determined Ned forced himself into a last effort. He used no
+words of persuasion, for Alan allowed Ned to take his hand, and
+thus, silently and slowly, the two moved forward again. Perhaps
+another half mile was made between rocks and down gullies and then
+Alan exclaimed pitifully:
+
+"It's no use, Ned, I can't, I can't. My feet." Burying his
+fevered face in his hands, the boy wept, partly in pain and partly
+because he knew that he was holding back his chum.
+
+At such periods Ned Napier was at his best. With kind words he
+sought to encourage his friend. He used the little water left to
+bathe Alan's face, and the last of his shirt in binding anew his
+friend's bleeding feet. He tried to joke and speculated on the
+possibilities of the smoke beyond them, but it was without avail.
+Poor Alan could not rise again. The fever of exhaustion was on him
+and with a last appeal to Ned to leave him the boy threw himself on
+the ground and fainted away.
+
+There was no doubt now as to what was to be done. Unless he could
+bring help to his friend in a short time Ned knew it would mean
+death. And that meant death for both, for young Napier would never
+abandon his friend. Like a drunken man Ned turned and stumbled
+forward.
+
+
+
+
+CHAPTER XXXIII
+
+A FORLORN DASH FOR HELP
+
+
+Am hour later Alan Hope, carried by the faithful Elmer Grissom and
+the jovial Bob Russell, was laid gently on a blanket by the fire
+whose smoke had attracted the attention of the ragged, worn
+wanderers. Not until the sun had set did the exhausted lad open his
+eyes again. But water and food had been forced through his lips and
+when reason came back strength was not far behind.
+
+Ned sat by his chum's side all day, bathing his face and making him
+as comfortable as possible; from Elmer's medicine packet. A few
+mouthfuls of food had sufficed Ned. But that night, when Alan came
+again to his senses, the four boys held a thanksgiving about a
+cheerful fire and ate together. But it was no banquet.
+
+What had happened was soon repeated to the weak but happy Alan.
+Elmer and Bob had waited and watched for ten days, using their
+stores sparingly and ready always for the return of Ned and Alan.
+Two days they had seen the Cibola a speck in the sky far to the
+west, and had watched it from the little waterfall on the edge of
+the plateau. Then it disappeared and they never saw it again. This
+was three days after the boys departed from Camp Eagle.
+
+Husbanding their provisions as well as they could, they at last
+decided to start on their return to the outside world.
+
+This was two days before. The tent and the heavier articles were
+hidden in a cache. Their food had been reduced to a meager
+quantity. They had two pounds of bacon, six pounds of flour, two
+ounces of tea and a little over a pound of beans. In addition they
+had a half dozen bouillon tablets, a little salt, pepper and sugar,
+and a complete and unopened medicine packet in which were quinine,
+adhesive plaster, cotton, bandages, morphine, and other needed and
+compact drugs. With this light pack each boy had a rifle and a
+revolver, a few cooking utensils and a blanket.
+
+Elmer had his own water bottle, and Bob improvised two out of the
+empty baking powder can and a lard pail.
+
+Thus equipped, Camp Eagle was abandoned, and led by their compass
+Elmer and Bob had set out bravely for Mount Wilson and the Chusco.
+But it was with no small regret that they made their way up the long
+slope behind them and then across the valley beyond. But, fresh and
+strong of limb, they pushed forward and with Mount Wilson as a
+landmark made camp on the second night in the timber on the slope of
+the outer range.
+
+Never wholly despairing of meeting Ned and Alan again, the two boys
+were frugal both of their strength and their stores. The food they
+carried would have been sufficient for a healthy man for perhaps a
+week. They could not count on reaching civilization again within
+that time, even with good luck. That meant half rations at the
+best. But if accidents came and delay even half rations would be
+cut down. So, that night, in camp, there was no feasting. A little
+tea, and a cake of dough apiece made their supper; and then they
+slept.
+
+In the morning as they were about to breakfast and be off again Bob
+caught sight of a deer. A little jerked venison would not come
+amiss, he thought, and as the ammunition was plentiful he darted
+through the woods in pursuit. The fact that Bob was a poor hunter
+probably saved Alan's life. He was gone an hour and a half and when
+he returned it was after seven o'clock.
+
+The two boys had just extinguished their fire and were about to
+shoulder their packs when a well-known but strained call arrested
+them.
+
+"Camp ahoy?"
+
+It was their leader, Ned Napier, his cheeks sunken, and his body
+swaying from weakness, but cheery as of old, advancing slowly
+through the trees.
+
+Food and a night's rest restored Ned's strength. "And now, my
+friends," said he in the morning, "these bandages and a little food
+and good companionship have worked wonders. We are all ourselves
+again. But we can't stay here, pleasant--as it is. Alan ought not
+to travel for another day and then he ought to have some husky
+attendant. Bob, you are nominated for that job. Elmer and I will
+take a few pinches of tea, the soup tablets, one revolver and a
+rifle and--"
+
+"And what?" exclaimed Alan, suspicious of Ned's suggestion.
+
+"And," continued Ned, "We'll just dash on ahead and bring you some
+help."
+
+"No, siree," shouted Alan. "Do you think get back to Clarkeville,
+one hundred and fifteen miles or more, on six soup tablets? And for
+me? If you think you ought to go, all right. But you'll take half
+of the food."
+
+"Or more," interrupted Bob, "give us a little flour and salt and
+some matches. I reckon I can get a deer before night."
+
+But Ned convinced them in the end that he was right. He argued that
+each mile he and Elmer made in advance was nearer help. Alan must
+advance slowly.
+
+"All you've got to do," he explained to Bob and Alan, "is to reach
+the Chusco, where Elmer camped, and take care of yourselves for
+seven or eight days. And we'll be there to help you, unless
+something happens. You won't have much to eat but you'll have water
+and you have ammunition."
+
+And at seven o'clock that morning they parted. Just before the
+farewells Alan called Ned to one side and said:
+
+"Hadn't you better take my bag?" indicating the jewel case under his
+arm.
+
+"Why?" answered Ned.
+
+"Well, you know we may never see each other again."
+
+Ned took his chum's hand.
+
+"Alan," he said, "we were not born to lose ourselves in the woods,
+much less to die there. We'll meet again all right. Don't you have
+any fears on that point. But if we shouldn't, I won't care for
+amethysts or pearls. If I don't see you again it'll be because I'm
+beyond the need of those things."
+
+There were handshakes and cheering, good wishes, and the relief
+section was off.
+
+"Elmer," said Alan, after the two had been trailing through the
+trees Indian fashion some time, "it is daylight at four o'clock and
+dark at seven--that's fifteen hours. Can you walk two miles an
+hour?"
+
+"Sho'ly," smiled Elmer, showing his white teeth.
+
+"Well, that's thirty miles a day. If we could do that for four days
+we'd be in Clarkeville!"
+
+"Clarkeville in fo' days it am den," echoed Elmer, "or bust."
+
+"We've got six soup tablets. If we dine on one at ten o'clock in
+the morning and one at seven o'clock in the evening we'll have
+regular meals for three days."
+
+"And de las' day we won't need none, we'll be in such a hurry,"
+added the colored boy, happy again in Ned's company.
+
+That was the spirit in which the expedition started. Late that
+afternoon they emerged from the timber and were on the sandy
+foothills where progress was faster. Ned's feet bothered him and he
+was in constant pain, but the adhesive plaster and cotton had been
+of the greatest help. There was no pause. The first day's schedule
+he was determined to make and at about eight o'clock the relief
+expedition gave a shout. The Chusco lay before them.
+
+A little fire, some tea and bouillon--made in the pan after the tea
+was consumed--and the two boys found a bed on the soft sand with no
+covering but the deep Mexican sky. At dawn they were up and away
+after a bath in the muddy river. Elmer was now the guide and he
+readily picked up Buck's old wagon trail. Sharp at ten o'clock a
+halt was made for breakfast, bouillon now without tea. Ned, his
+face a little more sunken and his legs a little more unsteady than
+the day before, was sitting on the ground resting his burning feet,
+when Elmer suddenly touched him on the shoulder, set the soup pan
+quickly on the sand and drew his revolver.
+
+Far down the trail a horseman was approaching. Behind him in the
+distance followed a wagon. What did this mean?
+
+"Well, whoever it is, we'll have the soup," said Ned.
+
+This consumed, Ned and his friend started forward.
+
+"If it's good luck we'll meet it sooner this way," said Ned, "if
+it's bad we'll know the worst quicker."
+
+But it was good luck. The rider soon galloped up and swung his wide
+hat in the air. It was Curt Bradley, the mayor of Clarkeville.
+
+
+
+
+CHAPTER XXXIV
+
+THE RESCUE
+
+
+They told Ned afterwards that he keeled over in the sand and fainted
+dead away, but he always insisted that he didn't faint, that he knew
+everything that was going on. Yet he did not hear a word of the
+long story told by Elmer. When he roused himself he was lying in
+the shade of the big freight wagon and a couple of cowboys were
+getting breakfast ready.
+
+Then Mayor Bradley explained his presence in that mysterious way in
+which bad news always travels friendly Indians had sent him word of
+the attack on Buck's outfit and of the death of the veteran
+plainsman. This news had just reached Clarkeville and Mayor Bradley
+had at once set out to find the body if possible, and assist those
+who escaped.
+
+Of course all speed was made toward the foothills and that evening
+Alan and Bob, the former only a shadow of the lively youngster who
+had left Clarkeville but two weeks before, were found and rescued.
+That night there was a new camp on the Chusco and meat and hot
+bread. The only shadow to dim the happiness of the rescued boys was
+the recollection of the murdered Buck.
+
+The return to Clarkeville was made by easy stages in four days, and
+even Alan was nearly his old self when that town was reached. One
+night's rest in real beds, with fresh linen from the baggage they
+had left behind them, and baths, removed the traces of privation and
+suffering. There was little more to detain Ned and Alan.
+
+A telegram was dispatched to Major Honeywell at Kansas City, where
+the boys and their patrons had agreed to meet. Then Ned's tool
+chest was forwarded by freight to Chicago. In company with Mayor
+Bradley Ned and Alan visited Mrs. Bourke, Buck's widow. Retaining
+enough to cover the costs of transportation to Kansas City he gave
+the widow what remained of his funds, nearly five hundred dollars,
+and all the heavy stores remaining in the corral.
+
+At midnight of that day four wide-awake and alert boys, neatly clad
+in summer suits, boarded the local train bound east for Albuquerque.
+The last hand they shook was that of Mayor Bradley.
+
+"Mr. Mayor," said Ned as he parted from his friend, "I'm sorry I
+can't tell you why we were here, or what we were doing. But you
+were our friend and we'll never forget you. Some day I'm going to
+show you how highly we regard you. And some day I hope I'll be able
+to tell you what our mission was."
+
+Three days later the quartette of boys sprang from the Limited in
+the Union depot at Kansas City. The parting had come. None of the
+boys knew what that meant until the last moment.
+
+"'Ned," said Bob Russell, once again in the field of his profession,
+"I've had many a strange assignment in my work and I expect to have
+many another, but I'll never have one like this. I've got the story
+of my life, but I haven't got yours. If the time ever comes when I
+can write it, when you are free to tell it, just remember your best
+friend, Bob Russell, reporter, Kansas City Comet."
+
+"Bob," answered Ned wringing his hand, "you have missed a good
+story. I'm sorry. It wasn't because you were not a good reporter.
+It was just our good luck. But if things work out the way I hope,
+I'm going to give you something better than a good story."
+
+"And," broke in Alan, "just want to say this: if chance ever throws
+adventures my way again I hope that the companions I share it with
+will always include Bob Russell."
+
+The details of how Ned and Alan, just one day late, kept their
+engagement with major Honeywell and Senor' Oje in the Coates House,
+and of the almost unbelievable report they made and the rich
+evidence of its genuineness that they submitted do not really belong
+in an account of the flight of the Cibola. Two things were done at
+once, however. A handsome gold watch was purchased and sent to
+Mayor Bradley with the compliments of Ned and Alan, and Senor Oje
+forwarded an additional check for a thousand dollars to Buck's
+widow.
+
+The report on the value of the stones carried from the treasure
+temple by the two boys was such that Senor Oje gave them his check
+for $25,000. Out of this each boy contributed part of his share
+toward a sum sufficient to give Elmer a business education. Finally
+the two boys bought a draft for a thousand dollars, payable to
+Robert Russell. With it went this note: "Please accept this as some
+slight compensation for the story you did not get."
+
+But in good time Bob Russell did get his story. For, otherwise,
+this narrative would never have been written.
+
+How it came about that Bob got his story; how the treasure left in
+the Turquoise Temple was finally lifted; how the young aeronauts in
+doing it battled successfully with a maelstrom in the clouds, were
+driven far out over the Pacific, cast away on a derelict and finally
+made an escape with their "sneering idol" by aeroplane into the
+wilds of Mexico, is a later and more remarkable chapter in the
+adventures of Ned Napier and Alan Hope, to be told in "The Air-Ship
+Boys Adrift, or Saved by an Aeroplane."

+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of

+exists because of the efforts of hundreds of volunteers and donations
+from people in all walks of life.
+

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

+<h3>
+CHAPTER I
+</h3>
+
+<h3>
+THE DEPARTURE OF THE OVERLAND LIMITED
+</h3>
+
+<p>
+The Overland Limited, aglow with lights, stood in the Dearborn
+Street station in Chicago waiting for eight o'clock and the last of
+its fortunate passengers. Near the entrance gates, through which
+perspiring men and women were hurrying, stood the rear cars of the
+train. Within these could be seen joyous passengers locating
+themselves and arranging bags and parcels.
+</p>
+
+<p>
+In fifteen minutes the long journey of Ned Napier and his chum Alan
+Hope to the far southwest was to begin.
+</p>
+
+<p>
+At the other end of the big shed, where the cars of the long train
+seemed to fade almost out of sight, four persons were anxiously
+awaiting the approach of the hour of departure. One of these, the
+conductor of the train, consulted his watch, as he had done several
+times already, holding it close within the glow of his green-shaded
+lantern.
+</p>
+
+<p>
+"It's getting pretty close to time, Major Honeywell," he said with
+some concern. "You're sure he'll be here?"
+</p>
+
+<p>
+The man addressed, who stood leaning lightly on a cane and whose
+soft dark hat and clothes indicated his military calling, showed
+similar concern, but replied confidently:
+</p>
+
+<p>
+"We have nearly fifteen minutes. Young Napier has a reputation for
+never failing. I'm sure he'll be here in time."
+</p>
+
+<p>
+"Here's the telegram," interrupted young Alan Hope, as he drew a
+yellow sheet from his pocket. "It is from Youngstown, Ohio, and
+says Ned's train is on time. He left Washington yesterday and if
+everything is all right he reached the Union Depot a half hour ago.
+He'll be here."
+</p>
+
+<p>
+"Well, you know we can't wait, much as I'd like to," replied the
+conductor. "You'd better have everything ready."
+</p>
+
+<p>
+"She's dat, sah," interrupted the fourth person of the group, a
+young negro, who, as he spoke, placed his hand on the side door of
+the car, and moved it on its easy running bearings.
+</p>
+
+<p>
+"You see, there isn't much time left," continued the sympathetic
+train official. "We're coupling up." And he nodded toward the
+gloom beyond the train shed out of which the big compound locomotive
+was already emerging. The military man with the cane became more
+apprehensive.
+</p>
+
+<p>
+"What shall we do if Ned fails to get here?" he said suddenly after
+peering down the long platform toward the busy end of the station.
+</p>
+
+<p>
+"Oh, we didn't go into this to fail," cheerily responded the youth
+by his side. "If we 'fall down' it won't be on a simple thing like
+this. He'll be here. It won't take us but three minutes to
+transfer the stuff when it gets here. Never fear. I'll just take
+another look in the car to make sure."
+</p>
+
+<p>
+As he did so the colored boy exclaimed:
+</p>
+
+<p>
+"It's all right. Here's de screws as he done tole us to git and
+here's de screw-driver outen de box as he done writ us to have ready
+and dar's de door all ready fur to fly open."
+</p>
+
+<p>
+To prove it the lad gave the wide door in the side of the car a
+shove, and as it ran back on its track a portion of the inside of
+the car was exposed. It was a peculiar car and worth description,
+for in it, next to the big engine and ahead of all the other cars of
+the almost endless train, Ned Napier, his friend Alan Hope, and
+their servant, Elmer Grissom, were to be the sole passengers on a
+most mysterious and, as it proved, most eventful journey. In
+railroad parlance the car was what is known as a "club" car. Half
+of the interior was bare and unfinished, like the compartment in
+which, on special and limited trains, baggage is carried. This part
+of the car, now exposed to view, was dimly lighted with one
+incandescent bulb. In the half-light it could be seen that the
+space was almost wholly filled with tanks, boxes, casks, crates and
+bundles, all systematically braced to prevent jarring or smashing.
+It was plainly not the luggage of ordinary travelers. Except for a
+narrow passageway in the center of the car and a space about five
+square next the open door, every inch, to the very ventilators of
+the car, was crowded with bound or crated, numbered and tagged
+packages. In the open space next the door Alan Hope now appeared.
+</p>
+
+<p>
+"Coming yet?" he asked with apparent confidence as he peered
+outside.
+</p>
+
+<p>
+The colored boy Elmer shook his head.
+</p>
+
+<p>
+Just then the conductor returned and again his watch.
+</p>
+
+<p>
+"Eight minutes," he said; "time's getting along and I've got to go
+back and see about my train. I don't want to make you nervous, but
+do you want us to take this car if fails to get here with the
+stuff?"
+</p>
+
+<p>
+"I suppose there's no need," replied the military man, beginning to
+show irritation. "But there's eight minutes yet."
+</p>
+
+<p>
+"I know," replied the conductor, "but after we are coupled up and it
+is time to leave we can't stop to cut this car out. We've got to
+have five minutes for that. At five minutes of eight you'll have to
+decide whether it is go or stay. I'm sorry&mdash;but you'll have to
+decide in a minute or two."
+</p>
+
+<p>
+"Decide it now," interrupted Alan from the open car door. "We're
+going and he'll be here."
+</p>
+
+<p>
+The Major appeared to be in doubt as to the wisdom of this, but
+before he could say anything Alan continued:
+</p>
+
+<p>
+"Couple up whenever you want to, Mr. Conductor, we'll be ready," and
+he sprang out of the car, his face set with determination.
+</p>
+
+<p>
+By that time the throbbing engine had silently moved up next the car
+and two grimy depot men with smoky torches had swung off the
+footboard to make the connections.
+</p>
+
+<p>
+"Got to know," repeated the sympathetic conductor. "Only five
+minutes." He looked at the Major for the final word.
+</p>
+
+<p>
+The latter peered down the long almost vacant platform. There was
+no one in sight but the late arrivals being helped aboard the cars
+in the far end of the station. Then he gave another look of appeal
+at his own watch as if in doubt what to say. To send a special car
+half way across the continent was no inexpensive project. And to
+send it without the person or the precious material that it was
+intended seemed not only a waste of money but foolish. Although the
+anxious man had both confidence and nerve it could be seen that he
+was in a quandary.
+</p>
+
+<p>
+"Five minutes," exclaimed the railway official. "Does she go or
+stay?"
+</p>
+
+<p>
+Before the man could answer, Alan faced him and with a hand on the
+Major's arm exclaimed:
+</p>
+
+<p>
+"Ned will be here, he can't fail; tell him we're going."
+</p>
+
+<p>
+The Major smiled. "That's it," he exclaimed suddenly. "Take her
+along. It's up to us to take care of ourselves."
+</p>
+
+<p>
+"Good," said the conductor, "I hope he'll make it."
+</p>
+
+<p>
+With a signal to couple on the engine he hurried away for a final
+inspection of his train.
+</p>
+
+<p>
+For a moment the three persons left behind stood in silence. There
+was a hiss of the engine as it pushed the connecting blocks together
+and then those waiting so anxiously could hear the jar of connecting
+valves as the brake hose were snapped. Confident as Alan was, it
+gave him a sinking feeling. Then, as the swish of tests sounded and
+the gnome-like figures of the depot men crawled from under the car,
+the Major looked again at his watch in despair.
+</p>
+
+<p>
+"Four minutes&mdash;"
+</p>
+
+<p>
+Before he could say more Alan caught sight of a movement among those
+gathered around the last car at the far end of the depot.
+</p>
+
+<p>
+"There he is!" he shouted and darted forward.
+</p>
+
+<p>
+"He sho'ly is," exclaimed Elmer, his white teeth showing, "and Yar's
+de screw driver and yar's de screws all ready."
+</p>
+
+<p>
+A slowly moving truck had carefully turned the end of the waiting
+train and, drawn by two baggage-room employees, was making its way
+along the platform. By its side walked a boy&mdash;a lad of about
+seventeen. One of his hands rested on the truck and his eyes were
+carefully fixed on the load it bore. This was a black, iron-bound
+case about four feet long, three feet deep and perhaps a yard in
+height. On each side in red letters were the words:
+</p>
+
+<p>
+"Explosive; no fire." Beneath this ominous legend were two large
+iron handles.
+</p>
+
+<p>
+When the men drawing the truck quickened their pace the boy spoke to
+them sharply and they fell again into a steady walk. For the
+curious onlookers through whom the strange little caravan passed the
+lad by the side of the truck seemed to have no concern. A traveling
+cap was pushed back from his young face and his keen and alert eyes
+and the tone of his voice indicated a quality that goes with those
+born to command.
+</p>
+
+<p>
+"Hello, Ned," came a ringing greeting from Alan as he ran forward.
+"They were afraid you wouldn't get here. But I knew you would.
+It's only a minute or two. Hurry."
+</p>
+
+<p>
+"Four," said the new arrival cheerfully and confidently.
+</p>
+
+<p>
+He gave his left hand to Alan and a better welcome in a cheery word
+of greeting, but his right hand did not leave the truck. Nor did
+his eyes leave it except for a moment.
+</p>
+
+<p>
+"And the Major?" asked the new arrival as the truck rumbled on.
+</p>
+
+<p>
+"Waiting to bid us good-bye."
+</p>
+
+<p>
+"Everything aboard and shipshape?"
+</p>
+
+<p>
+"Everything but this," and Alan glanced at the black case on the
+truck.
+</p>
+
+<p>
+"I've carried it a thousand miles like a baby," laughed Ned. "Rode
+with it all the way in the express car."
+</p>
+
+<p>
+"Then you didn't sleep last night?"
+</p>
+
+<p>
+Ned laughed. "It was too interesting," he answered, "and I can
+sleep to-night. But I'm glad it's here with no one killed and not a
+drop spilled."
+</p>
+
+<p>
+Advancing leaning heavily on his cane, the military man had hurried
+forward, his face radiant.
+</p>
+
+<p>
+"Welcome, my boy, and congratulations. But for goodness' sake
+hurry," he began hastily.
+</p>
+
+<p>
+Ned smiled again. "I think we had better not hurry this," and he
+pointed to the truck load. "That's the reason I'm late. I walked
+the horses from the Union Depot. You see we can't afford to spill
+our supplies. It was too hard to make and cost too much."
+</p>
+
+<p>
+In another moment the truck was abreast of the open car door.
+</p>
+
+<p>
+"Back her up," exclaimed Ned giving a hand himself to the tongue of
+the truck. Then, as the top of the truck came up flush with the car
+door and floor he sprang lightly on the truck and motioned the men
+to do likewise. For a moment they hesitated, but being reassured,
+Ned and Alan and the truck men lined up on either side of the big
+case. Slowly and carefully, with a brawny truck man on each side to
+help the less stoutly muscled lads, the case slid forward and with a
+"yeo-ho" or two from Ned it was soon in the car. Without a pause it
+was pushed at once into a space outlined on the floor.
+</p>
+
+<p>
+"And about two minutes to spare,"' cried the Major from the platform
+jubilantly and thankfully.
+</p>
+
+<p>
+"Not quite," laughed Ned, "but it'll be a half a minute and that's
+as good as an hour. The screws, Elmer."
+</p>
+
+<p>
+The colored boy, who had been busy keeping out of the way, sprang
+forward to perform his part of the apparently ticklish job. It was
+then seen that each bottom corner of the mysterious box had an iron
+flange. In the center of' each of these was a small hole.
+</p>
+
+<p>
+"Major," called out Ned as the truck men climbed out of the car,
+"these men were very obliging and careful."
+</p>
+
+<p>
+The Major understood him, and as he began searching his pockets for
+a bill Ned quickly inserted four screws in the waiting holes and
+with a few sharp turns of the screw driver made the case hard and
+fast to the floor of the car. Almost as quickly he threw the door
+into place and bolted it, and then with Alan hurried out for a last
+word to the friend who was so much interested in his success.
+</p>
+
+<p>
+"Was I right?" he exclaimed. "Half a minute?"
+</p>
+
+<p>
+"To the dot," enthusiastically answered the Major. "Now, boys,
+good-bye. Everything in that car is exactly as you planned and
+asked. From now on it is subject to your orders alone. What mine
+are you know. God bless you both and good luck to you!"
+</p>
+
+<p>
+As the boys took his hand Ned handed him a letter. "I'm sorry I
+couldn't have seen my mother again, but please send her this. I
+wrote it to-day on the train."
+</p>
+
+<p>
+Far down the line of cars came the words, "all aboard," and Elmer,
+cap in hand, sprang onto the steps.
+</p>
+
+<p>
+"Good-bye," exclaimed Alan, "and thank you for the great chance
+you're giving us."
+</p>
+
+<p>
+"Good-bye," said Ned, "if we fail in our work it won't be your
+fault, Major."
+</p>
+
+<p>
+And then, as the train began to move, the boys stepped aboard, off
+at last, after six weeks preparation, in search of the lost Cibola
+and the treasure of the Turquoise Temple.

+CHAPTER II

+
+<h3>
+NED'S MEETING WITH MAJOR BALDWIN HONEYWELL
+</h3>
+
+<p>
+Six weeks before Ned Napier and Alan Hope had set out on this trip
+Ned had been the surprised recipient of a mysterious note. In this
+message, written on the stationery of the Annex Hotel, he was urged
+to call on the writer the next morning at ten o'clock. With his
+mother's approval he had kept the engagement. The events which
+followed will explain how Ned came to take his momentous journey to
+the far southwest.
+</p>
+
+<p>
+Promptly on the hour Ned presented himself at the office desk. A
+clerk with a handful of letters gave him a half glance and turned
+away.
+</p>
+
+<p>
+"I say," began Ned in a voice that made the clerk turn quickly, "I
+want some information."
+</p>
+
+<p>
+The man stepped forward, leaned over the counter far enough to get a
+full view of his questioner, and answered:
+</p>
+
+<p>
+"All right, sonny. What can I do for you?"
+</p>
+
+<p>
+"You can tell me if Major Baldwin Honeywell is staying here."
+</p>
+
+<p>
+"Friend of Major Baldwin's?" asked the clerk, his smile broadening.
+</p>
+
+<p>
+"If Major Honeywell is stopping here I suppose he is paying well for
+his entertainment," replied Ned after a moment's pause.
+</p>
+
+<p>
+"Sure," answered the facetious clerk, "regular rates."
+</p>
+
+<p>
+"Perhaps that ought to include civil attention to those he has
+business with. I have an appointment with him at ten o'clock. I
+wish you would see at once that he knows I am here."
+</p>
+
+<p>
+The clerk's smile was not quite so broad now but he was still
+amused.
+</p>
+
+<p>
+"What name shall I give, son?" He was about to repeat the "sonny"
+that had grated a little on Ned's sense of the proprieties but he
+stopped short&mdash;and added: "Have you a card, Mr.&mdash;?"
+</p>
+
+<p>
+"I have no card and I don't call myself 'Mr.'," answered Ned, "but
+you can say that Ned Napier is here and will be glad to see Major
+Honeywell whenever it is convenient."
+</p>
+
+<p>
+At the mention of "Ned Napier" the clerk's airiness disappeared. A
+certain respect seemed to take its place. Then he leaned forward
+and said a good deal more politely: "You are not the Ned Napier?"
+</p>
+
+<p>
+"I never heard of any other one of that name," answered the boy.
+"But I think we are losing time. Please say I'm here."
+</p>
+
+<p>
+A moment later a page announced that Major Honeywell, in suite 8 A,
+desired Mr. Napier to be shown up at once. Reaching the apartment
+the page knocked and there was a quick "Come in."
+</p>
+
+<p>
+Hat in hand, and with all the manliness and dignity his seventeen
+years afforded, Ned stepped into the room. At a table a man had
+just risen as if from work on some papers. As the man turned to
+come forward and his eyes fell upon the lad he paused as if
+surprised. Ned Napier was neither large nor small for his age. But
+his circumstances had been such, financially, that his attire was
+plain and perhaps old fashioned&mdash;much of it the handiwork of his
+frugal and fond mother; and the absence of smart and up-to-date
+ideas in clothes and shoes made him look, perhaps, even younger than
+his years. Other lads of his acquaintance&mdash;those in his classes in
+high school&mdash;aped their elders. Ned's time and interests were too
+much given up to his boyish ambition to permit this.
+</p>
+
+<p>
+Ned saw a man of about sixty years, with snow-white moustache,
+dressed in blue. The man had every appearance of being both a
+soldier and an officer. His face was tanned as if by much exposure
+to the sun, but the line of white at the top of his forehead, where
+his hat gave protection, suggested that the color was both recent
+and transitory. Major Honeywell's hair, which was yet dark and only
+slightly streaked with gray, was too long to suggest present active
+service, as Ned at once concluded. His face, too, had something of
+the student in it, and this effect was increased by a pair of large
+gold spectacles with double lenses. The man's contracted eyes gave
+the youth the uncomfortable feeling of being microscopically
+examined, and Ned was for a moment ill at ease. The manner of the
+scrutiny was that of a scholar who had before him a strange new
+specimen. Ned, still with hat in hand, felt more like a dead bug
+than a very live boy. Then the white-mustached man smiled, took
+off his heavy-lensed glasses, and stepped forward with his hand
+extended.
+</p>
+
+<p>
+"I am Major Honeywell," he began in a low voice, "formerly of the
+regular army and later detailed on ethnological work for the
+Government. You are&mdash;"
+</p>
+
+<p>
+"Ned Napier," responded his youthful caller.
+</p>
+
+<p>
+"You must take no offense if I am a little surprised," exclaimed
+Major Honeywell; "I had supposed you would be older. Perhaps your
+surprise came first on receiving my note?"
+</p>
+
+<p>
+"It did," replied Ned; "I was surprised and so was my mother. But
+she thought I ought to come, although we could not imagine what you
+wanted."
+</p>
+
+<p>
+Major Honeywell smiled and motioned Ned to a chair with a
+graciousness that made the lad more comfortable. It had taken but a
+passing glance to reveal to the boy that he was in the presence of
+no ordinary man. The articles scattered about the room, which
+apparently were part of his host's traveling outfit, confirmed this.
+Of three leather cases or trunks in front of the mantel and within
+Ned's view, one was open. On the extended top of this, still partly
+covered with the folds of a light Indian blanket, were several flat
+and dull plates or dishes of Indian design, more or less broken and
+chipped. From the case came a pungent aromatic smell such as Ned
+had noticed in the "Early American" room of the museum. He was not
+quite sure what "ethno" meant, but he made a guess that it related
+to old Indian things, and this theory he confirmed to himself when
+he noticed on the table that Major Honeywell had just left another
+piece of pottery and by its side a large reading or magnifying
+glass.
+</p>
+
+<p>
+"A collector," thought Ned, more puzzled than ever.
+</p>
+
+<p>
+"I thank you for coming," said Major Honeywell finally. "It was
+good of you to do so. But I had supposed you were older&mdash;at least a
+young man," and he smiled again as if in some doubt.
+</p>
+
+<p>
+"Perhaps," replied Ned with just a shadow of resentment in his
+voice, "if you will tell me why you sent for me I can help you in
+making up your mind as to whether you were wrong in doing so. I'm
+seventeen."
+</p>
+
+<p>
+Major Honeywell arose, took off his glasses again and walked to
+where Ned was sitting.
+</p>
+
+<p>
+"I hope you'll not take offense, my boy. But my business with you
+is most important. It is possibly the most important thing that has
+ever come to me. Fate, or chance more properly, of course, seems to
+have brought us together. If what I have in mind and have partly
+hoped could be brought about, is brought about, you will have no
+reason to regret my sending for you. We must be sure of ourselves.
+So far we know almost nothing about each other. Since our
+acquaintance may mean a great deal to us let us be sure of
+ourselves. Therefore, you will pardon me if I ask you if you are
+the Ned Napier?"
+</p>
+
+<p>
+Ned laughed good-naturedly.
+</p>
+
+<p>
+"That's what the clerk down stairs asked me few moments ago&mdash;if I
+were the Ned Napier. Well, I never heard of any other Ned Napier.
+But boys don't carry credentials, you know, Major Honeywell. I'll
+take your word for it that you are Major Baldwin Honeywell, formerly
+of the United States Army, and now of the&mdash;what do you call
+it&mdash;ethno&mdash;?"
+</p>
+
+<p>
+"Ethnological survey," laughed the Major. "Then, since we know each
+other, I want to congratulate you, my young friend, on being one of
+the brightest, nerviest, and most promising young men of America.
+I've read about you and that's why I sent for you."
+</p>
+
+<p>
+Ned could only conclude one thing and it made him blush. "You mean
+my dirigible balloon experience last summer?" he asked with growing
+embarrassment.
+</p>
+
+<p>
+"I do," replied Major Honeywell with what Ned thought was wholly
+unnecessary warmth and enthusiasm, "and I want to shake the hand and
+congratulate the youngest, most daring and most promising balloon
+navigator in the world."

+<h3>
+CHAPTER III
+</h3>
+
+<h3>
+THE RELATION OF MIGUEL VASQUEZ
+</h3>
+
+<p>
+It may be well to recount how such a young lad as Ned had become so
+famous.
+</p>
+
+<p>
+Ned's father had been a consulting engineer with a fondness for
+aeronautics. When Mr. Napier died, a year before Ned's meeting with
+the Major, it was discovered that he was making in his little shop a
+small dirigible balloon to be used at an amusement park. Mr.
+Napier's death was sudden. Manufacturer's bills for the balloon bag
+and engine came due and Ned, young as he was, knew that he must pay
+them. Putting on all the dignity that his sixteen years would
+permit he called on the manager of the amusement park.
+</p>
+
+<p>
+"I hear your father is dead," said the manager. "I suppose we have
+lost the twenty-five per cent we advanced on the air ship."
+</p>
+
+<p>
+"Why do you suppose that?"
+</p>
+
+<p>
+"Because he had complete charge of the work and we have no one to
+take his place."
+</p>
+
+<p>
+"I mean to do that myself," said Ned.
+</p>
+
+<p>
+The manager smiled and shook his head. "No doubt you would try&mdash;you
+look it&mdash;but we don't care to experiment."
+</p>
+
+<p>
+"But you want the air ship, don't you? You've advertised it."
+</p>
+
+<p>
+"Yes, it was ordered&mdash;through your father. Since he is dead and
+cannot contribute his services, our agreement is void."
+</p>
+
+<p>
+"Very well," replied Ned. "Good day."
+</p>
+
+<p>
+"Look here," interrupted the manager, "what do you mean to do?"
+</p>
+
+<p>
+"I'm going out to sell an air ship."
+</p>
+
+<p>
+"You mean our air ship?"
+</p>
+
+<p>
+"You said the contract is void."
+</p>
+
+<p>
+The manager laughed again, but not as jovially.
+</p>
+
+<p>
+"You ought to get on," he exclaimed.
+</p>
+
+<p>
+"I've got to get on, and I'm going to do it by being on the square."
+</p>
+
+<p>
+"I guess you're right. What's your proposition?"
+</p>
+
+<p>
+"Since you've thrown up the contract I'm going to sell the balloon
+at a profit. The price is now $3,000. And I want a contract as
+operator for six weeks at $100 per week."
+</p>
+
+<p>
+The manager stared at Ned and then exclaimed. "I'll do it. You are
+the very youngster we want."
+</p>
+
+<p>
+That was how Ned Napier came to finish the air ship his father had
+planned, and how it happened all that summer that the papers printed
+news stories and Sunday specials with pictures of his daring
+flights, and how Major Baldwin Honeywell and other happened to speak
+of him as the Ned Napier.
+</p>
+
+<p>
+To return to the scene of Ned's meeting with the Major&mdash;
+</p>
+
+<p>
+"My name is Ned Napier," the boy began as soon as his host's
+cordiality gave him a chance, "and I am the young man the newspapers
+wrote about."
+</p>
+
+<p>
+"I certainly made no mistake in sending for you," exclaimed the
+soldier. "But, before I say more I want you to realize that this
+is, to me, a most important matter."
+</p>
+
+<p>
+"You mean it is&mdash;"
+</p>
+
+<p>
+"A solemn secret. I want secure your services in a desperate and
+daring adventure that will mean a great deal to me&mdash;and a great deal
+to you."
+</p>
+
+<p>
+"Certainly," was the boy's response. "I give you my pledge on that."
+</p>
+
+<p>
+A look of relief came into the old soldier's face.
+</p>
+
+<p>
+"If I furnished you the money," went on Major Honeywell suddenly,
+"could you produce in a short time a practical and manageable
+balloon?"
+</p>
+
+<p>
+Before the boy could answer the old soldier continued: "I don't mean
+one of those affairs in which ascensions of an hour or so are made.
+I mean one in which you could travel for several days&mdash;perhaps a
+week?"
+</p>
+
+<p>
+"No," said Ned, "it can't be done. No one has yet remained in the
+air in a balloon over fifty-two hours."
+</p>
+
+<p>
+Major Honeywell said nothing, but Ned could see that what he had
+told the Major had dashed some budding hope.
+</p>
+
+<p>
+"That is," Ned hastened to explain, "you couldn't do it unless you
+periodically renewed your supply of hydrogen. I really believe,"
+continued Ned, "that I ought to know more about what you are
+planning to accomplish."
+</p>
+
+<p>
+Again the white-mustached man was silent a few moments, and then he
+told without reserve the great secret. He began with an account of
+himself. Until three years before he had been an officer in the
+United States cavalry, stationed in the southwest. Then the
+President had assigned him to ethnological work. His special work
+was in the ruins of the Sedentary Pueblos. While scaling a cliff in
+this work he fell and permanently injured his left knee.
+</p>
+
+<p>
+Resigning from the army, he traveled for a year and then went to
+visit an old friend, Senor Pedro Oje, whose immense sheep herds in
+Southwestern Colorado had made their owner a millionaire.
+</p>
+
+<p>
+While here, hearing of an ancient nearby pueblo, just south of the
+Mesa Verde, Major Honeywell and his friend drove to the settlement.
+To Major Honeywell's surprise he found an old friend in Totontenac,
+the chief. As the two white men were about to leave, old Totontenac
+presented to his soldier friend an ancient funeral urn.
+</p>
+
+<p>
+Major Honeywell was almost paralyzed with astonishment when he saw
+that the vessel was sealed and that it bore on its side, instead of
+the conventional Aztec design, this inscription in black: "Miguel
+Vasquez, 1545."
+</p>
+
+<p>
+"What was in it?" asked Ned quickly when the Major came to this part
+of his narrative.
+</p>
+
+<p>
+"That man was undoubtedly a soldier who marched out of Mexico in
+1539 with Friar Marcos, the great explorer," went on Major
+Honeywell, ignoring the question, "and when others gave up the
+search for the famed seven cities of Cibola and the wealth of the
+Aztecs that every Spaniard believed rivaled the treasure of the
+Incas, this man kept on. Either by accident or design Miguel
+Vasquez was left by the expedition and six years later he wrote on
+cowhide and concealed in that vase one of the most valuable historic
+records extant in America to-day&mdash;confirmation that there was a real
+basis for the tales that lured the Spaniards to this region in quest
+of treasure."
+</p>
+
+<p>
+Stepping to a trunk Major Honeywell took from a compartment a tin
+tube. From this he extracted a stiff sheet of parchment-like
+material.
+</p>
+
+<p>
+"It's writing, isn't it?" exclaimed Ned.
+</p>
+
+<p>
+"Yes, and Spanish. It is Miguel Vasquez's last will and testament,
+written over three hundred and fifty years ago. And here is a
+translation of it. You may read it yourself. That is my
+secret&mdash;and yours now!"
+</p>
+
+<p>
+And these are the words that turned the current of Ned Napier's
+life:
+</p>
+
+<p>
+"A relation of Miguel Vasquez soldier of Spain made in the year 1546
+concerning the hidden city of Tune Cha. Coming out of Saint Michael
+in the Province of Culican I journeyed with Captain Marco de Nica in
+1539. At Vacupa I departed from him and remained now six years
+among those of this land. Three years I dwelt in the town of Acuco
+and heard often of the city of Tune Cha wherein is to be found the
+Temple of Turquoise than which none more beautiful is to be found,
+not even in Castile itself. Such I have seen with my own eyes. It
+standeth within a palace of five hundred rooms or more wherein are
+to be found priestly vessels of gold and silver. And this same
+palace or City of Priests is compassed about by a massive wall. And
+in the center of the palace standeth the Temple, facing the sun
+which is the sacred place of al Quivera, Arche and Guyas. And the
+walls of this Temple are naught but precious Turquoise even to the
+height of forty feet or more, and the pillars thereof are of gold
+and silver alternate. Knowledge of this hidden and beautiful city
+hath not been reported unto Spain nor even unto Nueva Espana. From
+Acuco it lieth thirty day's travel west of north and as I estimate
+in 36 degrees latitude in the mountains of Tune Cha. From the Rio
+de Chuco it lieth west six days' travel. Nor may it be discovered
+but by those who have knowledge of it.
+ Miguel Vasquez"<br />
+</p>
+
+<p>
+"What I had hoped to do," said Major Honeywell at last, "was to make
+the most perfect balloon ever built and discover through you this
+hidden temple of turquoise treasure. You say you cannot do it."
+</p>
+
+<p>
+Something he had never felt before shot through Ned's body. His
+face flushed and then grew pale under the spell that was on him.
+</p>
+
+<p>
+"Major Honeywell," he said suddenly, "I don't know of a balloon that
+can be made to fly for a week. But if it is necessary to have one
+to do what you wish I'll make it and I'll find Vasquez's Turquoise
+Temple."
+</p>
+
+<p><br /><br /><br /></p>
+
+<p><a id="chap04"></a></p>
+<h3>
+CHAPTER IV
+</h3>
+
+<h3>
+THE CONTRACT, AND LIQUID HYDROGEN
+</h3>
+
+<p>
+"I knew you'd do it," exclaimed Major Honeywell, beaming. "Now
+we'll have my friend Senor Oje up and get right at the details."
+</p>
+
+<p>
+"One moment, Major Honeywell. It is easy to say what I just told
+you. But it means I've got to do something no one has ever done.
+I've got to take with me&mdash;in the balloon, of course&mdash;the material to
+replace the gas I lose."
+</p>
+
+<p>
+"Well, that's easy, isn't it? For you&mdash;" qualified the old soldier.
+</p>
+
+<p>
+"I guess you don't know much about ballooning," laughed Ned.
+</p>
+
+<p>
+"Will money enable you to do it?"
+</p>
+
+<p>
+"I hope so! Other experimenters have tried to carry materials to
+make gas. I'm going to take the gas itself in a glass jar."
+</p>
+
+<p>
+"In a glass jar!"
+</p>
+
+<p>
+"Precisely. Liquefied hydrogen gas."
+</p>
+
+<p>
+At that moment Senor Pedro Oje, who had been summoned by Major
+Honeywell, entered the room. An almost Indian complexion and cast
+of countenance indicated his Mexican origin. What had taken place
+was related to Senor Oje, and he left no doubt that he was
+thoroughly in sympathy with the project. He soon put matters on a
+business basis.
+</p>
+
+<p>
+"We are to share alike in what is found, I understand," he said.
+"Major Honeywell will have a third interest because the secret is
+his. This young man is to have a third because the risk is his.
+And I am to have a similar portion for furnishing the capital. And
+that brings us to the real starting point," the Mexican capitalist
+continued. "What is it to cost?"
+</p>
+
+<p>
+"Ten thousand dollars at least," answered Ned instantly.
+</p>
+
+<p>
+"Phew!" exclaimed Major Honeywell.
+</p>
+
+<p>
+Senor Oje, not unused to speculative investments, gave no sign of
+surprise.
+</p>
+
+<p>
+"How shall it be arranged?" was his only comment.
+</p>
+
+<p>
+"Put that amount to my personal credit in the First National
+Bank&mdash;if you care to trust me."
+</p>
+
+<p>
+"We are trusting you with more than that," replied Major Honeywell
+with earnestness.
+</p>
+
+<p>
+"It will take me six weeks to make my arrangements. In that time,
+as I need the money, I will draw on the account," said Ned.
+</p>
+
+<p>
+"Very good," said Senor Oje; "I will draw up the agreement."
+</p>
+
+<p>
+"Now," continued Ned, addressing Major Honeywell, "what is your
+interpretation of the message of the Spaniard?"
+</p>
+
+<p>
+"Of course Vasquez's words must be modernized. What he termed the
+Tune Cha Mountains begin in New Mexico and extend northwesterly into
+Arizona and Utah. In many places their plateaus rise eight thousand
+feet above the sea. Their thousands of peaks and canyons are fit
+rivals of the wonders of the Grand Canyon of the Colorado. Nowadays
+they are known by many names&mdash;the Sierra Chusca, the Lokaeboka, the
+Carrisco. 'Thirty days' travel west of north' is not very definite,
+but it certainly locates the palace in the far northwestern part of
+these mountains.
+</p>
+
+<p>
+"The Rio de Chuco can only mean the Chusco river. The only place in
+its winding course that is six days' journey from the mountains is
+where it joins the Amarilla. This is south and east of Wilson's
+Peak, which is our landmark."
+</p>
+
+<p>
+"Very good," exclaimed Ned, briskly. "Now, what is the nearest
+point in civilization?"
+</p>
+
+<p>
+"Clarkeville, Arizona."
+</p>
+
+<p>
+"Then that is my starting point. This is June twentieth. I shall
+be ready by the last day of July. Of course I shall need a special
+car."
+</p>
+
+<p>
+"Very well," responded the capitalist. "I see you know what you
+want."
+</p>
+
+<p>
+"Incidentally," exclaimed Ned, "I shall, of course, be permitted to
+carry my own assistants."
+</p>
+
+<p>
+"Assistants? Yes, of course," replied Major Honeywell, "but they
+must be persons of discretion."
+</p>
+
+<p>
+"My chum, Alan Hope, who will make the ascension with me, will be
+one, and a colored boy, Elmer Grissom, who has helped me prepare for
+all my flights, will be the other."
+</p>
+
+<p>
+There was no dissent.
+</p>
+
+<p>
+"When shall I make my report?" Ned added.
+</p>
+
+<p>
+Major Honeywell and his friend conferred a moment.
+</p>
+
+<p>
+"Will five weeks be enough time for your exploration?"
+</p>
+
+<p>
+"I think so; perhaps less."
+</p>
+
+<p>
+"Then we will meet you at the Coates House in Kansas City on the
+first day of August."
+</p>
+
+<p>
+Senor Oje arose and lit a fresh black cigar.
+</p>
+
+<p>
+"It will be well for you and Major Honeywell to talk over these
+things while I see my Chicago banker," said he. And with a
+good-natured "Adios, Senores," he left the apartment.
+</p>
+
+<p>
+"Now, about this liquid hydrogen?" began Major Honeywell at once.
+</p>
+
+<p>
+"Well," said Ned, "instead of ballast, I'm going to carry reserve
+hydrogen with me."
+</p>
+
+<p>
+"And is that so difficult?" asked the Major.
+</p>
+
+<p>
+"Impossible, if you try to carry material to make the gas," answered
+the boy.
+</p>
+
+<p>
+"And so you are going to carry it in liquid form?"
+</p>
+
+<p>
+"I'm going to try, although the making of liquid hydrogen is, so
+far, pretty much a theory. It has been made only under tremendous
+pressure and at minus 423 degrees Fahrenheit."
+</p>
+
+<p>
+The Major whistled.
+</p>
+
+<p>
+"That is so cold that ice is red hot comparatively," explained Ned.
+"This work must be done, in Washington."
+</p>
+
+<p>
+They discussed the balloon itself, and the car and the engine for
+propelling it; where these were to be made in the East, and how they
+were to be forwarded to Chicago as they were completed. Ned himself
+was to go East at once and remain there until the last thing was
+accomplished.
+</p>
+
+<p>
+Ned's chum, Alan Hope, had just taken employment for the school
+vacation in a large sporting goods store not far from the hotel. A
+few minutes later Ned walked leisurely into this store and sought
+out the fire-arms department, where Alan was on duty.
+</p>
+
+<p>
+"Hello, Ned," exclaimed Alan, "what do you think of this?" And with
+a smile he handed him an automatic pistol he was inspecting.
+</p>
+
+<p>
+Restraining himself, Ned looked it over carefully.
+</p>
+
+<p>
+"It holds ten cartridges and it's a beauty," declared Alan.
+</p>
+
+<p>
+Ned weighed it carefully in his hand. "What's it worth?" he asked
+with dignity.
+</p>
+
+<p>
+"Eighteen dollars."
+</p>
+
+<p>
+"I think we'll need three of them!"
+</p>
+
+<p>
+Alan laughed.
+</p>
+
+<p>
+"And there are a good many other things I think we shall need," went
+on Ned, soberly.
+</p>
+
+<p>
+"This hot weather is pretty bad on some people," laughed Alan.
+"But, by the way, who are 'we?"'
+</p>
+
+<p>
+"You and Elmer Grissom and I," answered Ned carelessly.
+</p>
+
+<p>
+"And where are we going?" continued Alan, who was not unused to
+Ned's joking.
+</p>
+
+<p>
+"On a little run in a private car down into New Mexico."
+</p>
+
+<p>
+Alan looked at him a moment and then determined to have the joke
+out.
+</p>
+
+<p>
+"Then what are we going to do?" he asked, still laughing.
+</p>
+
+<p>
+"Make a trip through an unexplored mountain region in the best
+dirigible balloon ever built."
+</p>
+
+<p>
+Alan wondered just where the joke came in. "And then?" he
+continued.
+</p>
+
+<p>
+"Discover enough hidden treasure of jewels and silver and gold to
+make us rich."
+</p>
+
+<p>
+"Shall I get you a cabbage leaf and some ice water?" asked Alan.
+</p>
+
+<p>
+"Get your father's consent that you can go; that'll be all,"
+announced Ned and then, breaking into a laugh, he relieved the
+perplexed Alan by explaining what had just taken place. In ten
+minutes Alan had secured permission to be off for the remainder of
+the day and the two boys hurried away for luncheon, to revel in
+dreams of their great opportunity.
+</p>
+
+<p>
+By night Mrs. Napier had consented, though with tears, to Ned's
+going, and later Alan's father reluctantly did the same. As Ned was
+to leave the next afternoon and had to see Major Honeywell and Senor
+Oje in the morning it was a busy evening that the two boys spent in
+Ned's workshop.
+</p>
+
+<p>
+At one o'clock in the morning Alan's work in Chicago was outlined
+and Ned's needs in the East were all listed.
+</p>
+
+<p>
+"And now," exclaimed the tired but exuberant Alan, "it is all
+arranged but the name. What are we to call the air ship?"
+</p>
+
+<p>
+"The 'Cibola,'" answered Ned without hesitation, "the dream of the
+Spanish invaders and our hope of success."

+<h3>
+CHAPTER V
+</h3>
+
+<h3>
+A DINNER PARTY ON THE PLACIDA
+</h3>
+
+<p>
+The long, heavy, limited train on which the young air ship boys were
+at last embarked on their extraordinary mission pulled slowly out of
+the station.
+</p>
+
+<p>
+Ned made a quick survey of the Placida. Coming out of the baggage
+end he passed first into a drawing room. In this were two sections
+that opened up into four berths. Beyond the berths a passageway led
+to a private stateroom. When the boys reached the stateroom, Elmer
+was standing at the door with a happy smile on his face.
+</p>
+
+<p>
+"Fo' de captain," exclaimed the colored boy.
+</p>
+
+<p>
+"Where are you to bunk, Alan?" Ned asked, quickly.
+</p>
+
+<p>
+"Oh, the crew is in the main room."
+</p>
+
+<p>
+"Not much," exclaimed Ned. "We're partners in this enterprise. I
+don't have any better than the rest."
+</p>
+
+<p>
+And in another moment he had dropped his valise alongside Alan's
+berth.
+</p>
+
+<p>
+"We'll keep the little room for consultations," he said with a
+laugh, "when we don't want Elmer to hear us talking about the
+Indians."
+</p>
+
+<p>
+The colored lad grunted.
+</p>
+
+<p>
+"Can't scare me wif no Injun talk," he said. "I specs I ain't half
+so 'fraid o' Injuns as I is o' dat stuff in de black box."
+</p>
+
+<p>
+"And it's time to attend to the 'stuff,'" interrupted Ned.
+</p>
+
+<p>
+They returned to the baggage room.
+</p>
+
+<p>
+"Now," Ned began, "the door to this car must be kept locked except
+when the train crew are compelled to come through. We, in turn,
+must be careful about fire and lights. But, for fear of accident, I
+have taken some precautions."
+</p>
+
+<p>
+Alan and Elmer then saw that the top of the case was fitted with a
+lid the edges of which were bound with rubber. In the center of the
+covering was a short spout.
+</p>
+
+<p>
+"What's the use of an air and gas proof top with a hole in it?"
+asked Alan, inspecting it curiously.
+</p>
+
+<p>
+"Maybe dat's to let de air in and de lid's to keep de hydrogum from
+gettin' out," volunteered the colored boy.
+</p>
+
+<p>
+Ned was too busy to answer the one or to laugh at the other. He had
+unlocked the lid and thrown it back. About six inches beneath the
+top of the case stood eight iron boxes&mdash;two rows with four boxes in
+each. These boxes, six inches square, were each about three feet in
+height and in each could be seen the neck of a glass vessel.
+Securely packed in their iron jackets to prevent breaking, stood the
+glass receptacles, open-mouthed and apparently empty. But down
+below the shadowed rims were soft clouds of gaseous vapor, beneath
+which reposed the precious contents that had cost Ned over a
+thousand dollars&mdash;the liquid hydrogen.
+</p>
+
+<p>
+On top of the square iron buckets was coiled eight or ten feet of
+rubber hose. Taking it out Ned closed and locked the lid. He then
+screwed one end of the hose onto the open spout and, springing to
+the top of the case, passed the other end out of the open
+ventilator.
+</p>
+
+<p>
+"Now," Ned explained, "we are in less danger. Difficult as it is to
+condense hydrogen, it is more difficult to keep it in liquid form.
+It constantly seeks to return to gas. In a closed place it might
+make trouble."
+</p>
+
+<p>
+Elmer had already disappeared, with popping eyes and mumbles of
+protest. Alan proudly exhibited to his friend the results of his
+share of the work of preparation. Every crate, box, barrel and
+package was numbered and labeled and securely fastened in place.
+</p>
+
+<p>
+On one side of the car stood five large oak tanks, looking like the
+famous beer tuns of Germany.
+</p>
+
+<p>
+"I can make more hydrogen in those than you've got in your black
+box," Alan exclaimed jokingly.
+</p>
+
+<p>
+"I'll have a better look at them in the daylight," finally said Ned;
+"and now those easy chairs in the other car would feel pretty good."
+</p>
+
+<p>
+"Aren't sleepy, are you?" asked Alan, forgetting that his chum had
+not slept the night before.
+</p>
+
+<p>
+"No," said Ned, "only happy. But I'd be happier if I had had time
+to get a good hot supper."
+</p>
+
+<p>
+"All ready, sah, in de stateroom," announced Elmer's cheerful voice.
+</p>
+
+<p>
+Both boys turned&mdash;Ned in surprise.
+</p>
+
+<p>
+"Supper's all ready, sah!" continued the colored boy, "and waiting
+fo' you all."
+</p>
+
+<p>
+In the stateroom was a sight to arouse a sleepy boy and to delight a
+hungry one. In the middle of a small table was a bunch of pink
+roses. On either side, in a dish of cracked ice, was the half of a
+luscious cantaloupe. Silver knives, forks and spoons, sparkling
+glass-ware and snowy napkins at once revealed the resources of the
+Placida's pantry.
+</p>
+
+<p>
+"Well, I'll be jiggered!" exclaimed Ned.
+</p>
+
+<p>
+"Pretty nifty, eh?" laughed Alan.
+</p>
+
+<p>
+"Well, if this isn't the last straw!" exclaimed Ned as they seated
+themselves. "But I want to thank you both. I didn't know how
+hungry I really was&mdash;"
+</p>
+
+<p>
+He was about to plunge a spoon into the fragrant, cool melon when he
+saw a folded note by his plate. Opening it he read:
+</p>
+
+<p>
+"Dear Ned: Good luck and good voyage. The roses are from my own
+garden. Bring me a turquoise ring.
+ MARY HOPE."<br />
+</p>
+
+<p>
+It was from Alan's sister.
+</p>
+
+<p>
+"Shall we do it, Alan?" he cried.
+</p>
+
+<p>
+"Shall we?" answered Alan wringing his chum's hand. "We'll do it
+or&mdash;"
+</p>
+
+<p>
+"Is you all ready for dis?" asked the young chef suddenly appearing
+with a smoking broiled steak. "It can't wait no longer."
+</p>
+
+<p>
+And it did not have to.
+</p>
+
+<p>
+An hour later the two happy boys sat on either side of the table in
+the drawing room of their car.
+</p>
+
+<p>
+"Are you getting nervous?" began Alan.
+</p>
+
+<p>
+"About what?" asked Ned.
+</p>
+
+<p>
+"Oh, about everything. The responsibility for this car and the
+setting up of your balloon, and the trip itself."
+</p>
+
+<p>
+"Are you?" exclaimed Ned.
+</p>
+
+<p>
+"My, no, I'm not. But then I'm not the captain. But I thought you
+might be."
+</p>
+
+<p>
+"Aren't we getting along all right?"
+</p>
+
+<p>
+"Perhaps too well," Alan answered.
+</p>
+
+<p>
+"Never talk that way," interrupted Ned decisively. "Everything is
+happening as it does because we planned it just that way. Things
+can't go too well. That is a foolish idea. The good fortune of
+careful preparation should only confirm your judgment."
+</p>
+
+<p>
+This was the sort of advice Alan had to take now and then from his
+friend; but it always did him good.
+</p>
+
+<p>
+"Then you don't believe in good luck?" rather sheepishly suggested
+Alan.
+</p>
+
+<p>
+"I believe in it, yes," replied Ned, "if it comes&mdash;and I never put
+it aside. But I never count on it."
+</p>
+
+<p>
+Sleep seemed to have fled from Ned's eyes. Although Alan suggested
+that it might be well to turn in early and be up early, Ned insisted
+on seeing Major Honeywell's chart of the country they were to
+explore, saying that he had another night on the journey in which he
+could sleep.
+</p>
+
+<p>
+The chart was really only a rough pencil sketch. The instructions
+were more in detail.
+</p>
+
+<p>
+"This country, now a portion of the reservation of the Navajo and
+Southern Ute Indians, is a wilderness," Major Honeywell wrote.
+"White men do not visit it because the Indians will not permit them.
+Mining prospectors who have tried to do so have been murdered."
+</p>
+
+<p>
+"Cheerful, isn't it?" interrupted Alan.
+</p>
+
+<p>
+"This jumble of mountains has no connection with our two great
+western mountain ranges. The towering plateaus, cut with yawning
+canyons, are plainly the result of some special volcanic action.
+This unknown region extends over a hundred miles northwest and
+southeast, and on all sides drops suddenly into the sandy deserts.
+At Clarkeville the desert begins at once. If you will start a
+little east of north and locate the Indian village of Toliatchi,
+twenty miles away, you will be on the Arroyo Chusco. Although the
+bed of this stream may be dry it can be traced northward sixty-five
+miles, where it unites with the Amarilla, eighty-five miles from
+Clarkeville. At the juncture of these water courses, if you face
+west, the roughest part of the Tunit Chas will confront you. At
+your right will be Wilson's Peak. That portion of the Tunit Chas to
+the southwest forms the Lu-ka-ch-ka mountains. To the northeast lie
+the Charriscos. Somewhere in these mountains lie the temple and the
+treasures we seek."

+<h3>
+CHAPTER VI
+</h3>
+
+<h3>
+BOB RUSSELL OF THE KANSAS CITY COMET
+</h3>
+
+<p>
+When the Overland reached Kansas City at nine o'clock the next
+morning the air ship boys were just finishing an appetizing
+breakfast of fruit, omelet, pancakes and coffee. The Placida, their
+special car, came to a stop at the far end of the station train
+shed, and, covered with dust as it was, and almost hidden among
+hissing engines and baggage and express cars, there seemed little
+reason for it to attract attention. Of course it was not ignored by
+the railway officials. No sooner was the train at rest than the
+depot master and the division superintendent were knocking at the
+door. They had special orders concerning the car, and immediately
+wheels and brakes were being tested and ice and water were being
+taken aboard.
+</p>
+
+<p>
+The railway officials made a quick inspection of the car, asked if
+anything was needed, and were soon gone. A few minutes after they
+had left a young man suddenly appeared, dodging among the cars. He
+sprang on to the rear step of the Placida, but before he could enter
+the car, the door of which had been left open by the departing
+officials, the vigilant form of Elmer Grissom blocked his way.
+</p>
+
+<p>
+"Who's in charge here?" demanded the stranger. "I'm a reporter and
+want to see him in a hurry."
+</p>
+
+<p>
+The railway officials had been admitted through the baggage portion
+of the car, but Elmer knew that this way was not open to everyone.
+He understood the need of secrecy, and politely forcing the reporter
+out of the door on to the platform he led him to the front of the
+car.
+</p>
+
+<p>
+"If you'll give me yo' card," he then said with dignity, "I'll take
+it in, sah."
+</p>
+
+<p>
+As he was about to do so, Ned and Alan emerged from the car for a
+few mouthfuls of fresh air.
+</p>
+
+<p>
+"Hey!" exclaimed the impatient young man, "I'd like to see the man
+in charge of this car. It's important and I'm in a hurry. I'm a
+reporter for the Comet."
+</p>
+
+<p>
+The boys smiled.
+</p>
+
+<p>
+"We are in charge," answered Ned. "What can we do for you?"
+</p>
+
+<p>
+The reporter seemed taken somewhat aback at seeing two youngsters
+directing a special car. His bearing changed at once.
+</p>
+
+<p>
+"I've been sent to get a story about where you are going and what
+you are going to do," he said with a little more consideration;
+"that is, if you care to tell."
+</p>
+
+<p>
+Ned puckered up his lips and thought. He had met reporters before
+and he knew what a "story" meant.
+</p>
+
+<p>
+"I think we don't care to say," he replied in a moment. He did not
+even care to say it was a secret. Even that admission, he knew,
+would be a basis for something that might interfere with his plans.
+</p>
+
+<p>
+"Our correspondent in Chicago says you left there last evening with
+a carload of new and powerful explosives."
+</p>
+
+<p>
+"Was such a story printed this morning?" asked Ned, eyeing the
+reporter closely.
+</p>
+
+<p>
+"I think not," said the reporter, "but we are an afternoon paper,
+you know. We have a report that you are on your way to Mare Island,
+California, and that you have a carload of explosives for the navy."
+</p>
+
+<p>
+"Was such a story printed this morning?" repeated Ned, smiling
+again.
+</p>
+
+<p>
+"No, it wasn't. But it will be this afternoon," answered the young
+man impatiently.
+</p>
+
+<p>
+"If such a report had been known in Chicago last night," replied Ned
+sharply, "it would have been in every newspaper in that city and
+this city this morning. No correspondent sent you such a story.
+You are a poor guesser."
+</p>
+
+<p>
+The reporter was at least four years older than Ned and Alan.
+Therefore, he gave a little start of surprise. He had been trapped
+in a trick that he had often worked successfully on many an older
+person. For Bob Russell, easily the brightest and quickest-witted
+reporter in his city, thus to be turned down by two "kids" would
+never do. Without wasting time to deny Ned's charge, he tried a
+belligerent role.
+</p>
+
+<p>
+"Do you deny you have newly invented ammunition in that car?" he
+exclaimed brusquely.
+</p>
+
+<p>
+"I deny nothing and refuse to be put in the attitude of doing so,"
+calmly answered Ned. "Although it happens you are wrong again."
+</p>
+
+<p>
+The young man laughed and again changed his tactics.
+</p>
+
+<p>
+"Well, look here, boys, what's the use of getting mad about this?
+You're working on something, just as I'm working on a newspaper.
+You've got a good story somewhere about you and I'd like to have it.
+What's the matter with being good fellows and loosening up?"
+</p>
+
+<p>
+"Because it is purely a business matter in which the public would be
+too much concerned if it knew what we were doing."
+</p>
+
+<p>
+"Well, whatever it is, it's good&mdash;I know that," replied the young
+journalist, laughing, "and I'm sorry I'm not in it with you&mdash;special
+car&mdash;flowers&mdash;traveling like railroad presidents. I'm on. But,
+say, when this thing breaks I'd like to be in on the yarn. I was
+lying. I never heard of you before the train pulled in. But you
+know the railroad people are on. They told me you had a black case
+marked 'Explosive.' That's all I know. Say, couldn't you tell me
+this&mdash;are you going through to the coast?"
+</p>
+
+<p>
+Ned relented a little.
+</p>
+
+<p>
+"Perhaps," he said smiling, "we might go to the coast."
+</p>
+
+<p>
+"You might?" interrupted the reporter eagerly.
+</p>
+
+<p>
+"Or we might stop in the mountains."
+</p>
+
+<p>
+The reporter looked perplexed.
+</p>
+
+<p>
+"Then you've got something to do with mining?" interrupted the
+impulsive journalist, "and it isn't the navy yard. But you came
+from Washington! I know that, you see."
+</p>
+
+<p>
+"Yes," volunteered Ned, "but we might be from the Hydrographic
+Office."
+</p>
+
+<p>
+"Cloud breakers," quickly interrupted the reporter again. "How's
+that for a guess? Are you rain makers?"
+</p>
+
+<p>
+"What are they?" innocently asked Alan.
+</p>
+
+<p>
+The reporter saw he was wrong.
+</p>
+
+<p>
+"I give it up," he said shrugging his shoulders. "You are two wise
+lads."
+</p>
+
+<p>
+"Not wise," suggested Ned, "but attending strictly to our business."
+</p>
+
+<p>
+"Right you are," answered the reporter.
+</p>
+
+<p>
+"I've got to leave you to have a look through the train. Sorry I'm
+not in on this. Where ever you're going, it looks good to me. When
+you come back, don't forget me. Save the story for me, Bob Russell
+of the Comet."
+</p>
+
+<p>
+Handing his card to the boys with a cheery "So long!" he was gone.
+The boys felt a little relieved. They had done what they could to
+protect the interests of their patrons and themselves by keeping
+their mission a strict secret. So far as Ned knew, the only persons
+who had knowledge of what they were doing and where they were going
+were his mother and sister, Alan's family, and Major Honeywell and
+Senor Oje. Not even Elmer Grissom's parents knew where he was
+bound&mdash;it was sufficient for them to know that he was with Ned. Of
+course the railway people knew where the car was to stop. Beyond
+these it was necessary for no one else to know what was being
+done&mdash;not even the manufacturers who made the balloon, the engine and
+their precious gas. But what the young air navigators desired and
+what Bob Russell wanted were two different things.

+<h3>
+CHAPTER VII
+</h3>
+
+<h3>
+THE MAKING OF A NEWSPAPER STORY
+</h3>
+
+<p>
+Let us see whether the young reporter was baffled by the reticence
+of the secretive boys.
+</p>
+
+<p>
+"Every one to his trade," murmured Bob Russell, as he hastened from
+Ned and Alan, "and now, me to mine."
+</p>
+
+<p>
+Bob was what was known on his paper as the "depot reporter." It was
+not the most important assignment, for usually his work consisted
+only in describing such notable personages as passed through the
+city and now and then in interviewing the more important of these.
+But this day he was confronted with a mystery and it was his
+business to solve it. He acted quickly.
+</p>
+
+<p>
+Hurrying after the depot master, with whom of course he was
+friendly, he persuaded that official to go at once to the conductor
+of the train and ascertain the names of the boys. This was a simple
+thing, done in that manner, for even the passengers in a special or
+private car must have regular tickets. The conductor at once
+revealed the identity of the three passengers. Although Bob knew
+the conductor, he realized that he stood a chance of being refused
+even thin information if he asked for it personally.
+</p>
+
+<p>
+While his friend the depot master was getting this information, Bob
+quickly, but apparently carelessly, approached the head brakeman who
+had helped bring the train from Chicago. It was Tom Smithers&mdash;also
+a friend of Bob's, who made a point of knowing every employee
+running into the station.
+</p>
+
+<p>
+"I see you've got the Placida with you?" began Bob indifferently.
+</p>
+
+<p>
+"Yep," answered Tom, "and loaded to the axles. All except
+passengers. She's running light on them. Two boys and a coon."
+</p>
+
+<p>
+"I just had a talk with them," remarked Bob, carelessly offering the
+brakeman a cigar. "Pretty dusty, eh?" After a moment's casual talk
+Bob returned to the subject.
+</p>
+
+<p>
+"I guess those kids must be next&mdash;running a car with locked doors."
+</p>
+
+<p>
+"Locked doors!" snorted Tom, putting his cigar away for a
+surreptitious smoke. "Not on your life. Not against me. You bet
+she was open whenever I rang."
+</p>
+
+<p>
+"But it might just as well have been locked," said Bob. "The place
+is so jammed full of stuff. I couldn't make out what it was, but
+there was a wad of it."
+</p>
+
+<p>
+The unsuspecting brakeman then gave Bob what he was hoping to get.
+</p>
+
+<p>
+"Well, I stopped and saw it," he confessed. "I roused up the coon
+after midnight to have a look at the ropes and when I came back I
+took my time. They got a case of powder or dynamite in there marked
+'Explosive.' I didn't bother that but the rest was plain. Half the
+boxes in the car were labeled 'balloon works' or 'motor works.'
+It's a balloon show&mdash;nothing else."
+</p>
+
+<p>
+"Where is the car going?"
+</p>
+
+<p>
+"They ain't consulted me," laughed Tom.
+</p>
+
+<p>
+A few moments later Bob was in the office of the division
+superintendent. When he left he knew that the Placida would be
+dropped on the only siding at the little town of Clarkeville in New
+Mexico. He had also looked over the best map in the offices and
+fixed in his mind the topography of the adjacent country.
+</p>
+
+<p>
+Before half past nine Bob had presented these scattered facts to his
+city editor.
+</p>
+
+<p>
+"It's a story, all right, Bob, and a good one. Go to it," said the
+editor. And Bob did the best he knew how&mdash;in a newspaper way. On
+the suggestion of the editor he telegraphed to the representative of
+the Comet in Chicago: "Who is Ned Napier?" In a little over an hour
+he had a hundred and fifty word telegram outlining Ned's aeronautic
+career and concluding: "Why? What do you know? Napier not here.
+Family won't talk."
+</p>
+
+<p>
+Then Bob began his story. It was, for a reporter of his experience,
+brilliant, with good deductions, good guesses and good ambiguous
+generalities. It seemed to tell more than it really did.
+</p>
+
+<p>
+At four o'clock that afternoon Ned and Alan were speeding over the
+green and fertile prairies of middle Kansas in blissful ignorance of
+what Bob Russell had done. Under striking headlines appeared the
+following story:
+</p>
+
+<p>
+"Ned Napier, the famous young aeronaut of Chicago, passed through
+the city this morning on his way to the southwest to execute the
+most daring and important balloon journey ever undertaken in this
+country. Accompanied by an assistant, Alan Hope, and on board a
+special car packed with $50,000 worth of apparatus he will proceed
+to Clarkeville, an insignificant town in New Mexico, from which
+place he will make his hazardous flight over the mountains lying to
+the north. The aerial journey may possibly extended over the Sierra
+Nevadas as far as the Pacific Coast.
+</p>
+
+<p>
+"The details of the expedition are not made public, as young Napier
+has been retained by the authorities at Washington and is operating
+under a strict pledge of secrecy. The knowledge that such an
+expedition is under way was made known for the first time to the
+representative of the Comet by Mr. Napier at the Union Station this
+morning. While slow to discuss the ultimate object of his trip Mr.
+Napier talked of his plans in a general way.
+</p>
+
+<p>
+"'I represent the Hydrographic Department,' he said to the reporter,
+'and the journey I am about to make may extend from Clarkeville as
+far as the Pacific. I hope it will accomplish what the department
+has planned, but you know that we who are in this profession are
+always prepared for failure. My assistant and I may easily have our
+lives crushed out on the rugged peaks of the mountain chain we are
+attempting to cross.'
+</p>
+
+<p>
+"Mr. Napier suggested that some might conclude that he had been sent
+out as a 'rain maker,' or 'cloud breaker' in an attempt to secure
+rain for the arid plains, but he laughed at this idea.
+</p>
+
+<p>
+"In the government's special car, carefully safeguarded, is carried
+a large can of a new and powerful explosive. In exhibiting this to
+the reporter Mr. Napier good-naturedly said:
+</p>
+
+<p>
+"'I am sorry I cannot tell the public the exact character of this
+new explosive. But the secret belongs to the government.'
+</p>
+
+<p>
+"When it was suggested that the explosive might be destined for
+certain elaborate experiments in the unpopulated wilderness of the
+region to which the expedition is now hastening on the Limited, Mr.
+Napier would only answer;
+</p>
+
+<p>
+"My lips are sealed. I can say no more. But I compliment the
+Comet in discovering what all the eastern papers have missed&mdash;that a
+stupendous thing is projected and that I have the honor, with my
+friend, Mr. Hope, to attempt it."
+</p>
+
+<p>
+Then followed an elaborate rewritten version of what had been
+telegraphed from Chicago concerning Ned. After this was a detailed
+account of the car, not omitting little Mary Hope's bouquet of faded
+roses, which in Bob's story became "a wealth of cut blossoms, the
+tribute of Mr. Napier's scientific friends."
+</p>
+
+<p>
+What Bob wrote was in type by twelve o'clock. Three hundred words
+of it were telegraphed to the Chicago evening newspapers. Sharp at
+six o'clock that evening the Chicago correspondent of the New York
+World sent advice to his paper that he had a story on the mystery of
+what Ned Napier was about to do for the government. Word came back
+at once to send on the story.
+</p>
+
+<p>
+At ten o'clock the telegraph editor of the World in New York took
+the account just received to the managing editor of the paper.
+</p>
+
+<p>
+There was a minute's consultation, a nod of the head, and at twelve
+o'clock that night Bob Russell was awakened to respond to a
+telephone call. It was his own managing editor who read him this
+telegram:
+</p>
+
+<p>
+Managing Editor, Comet, Kansas City
+</p>
+
+<p>
+Send man at once to follow Chicago balloon man and discover mission.
+Advance funds and draw on us. Will share story with you.
+</p>
+
+<p>
+Managing Editor,
+New York World.
+</p>
+
+<p>
+It is hardly necessary to say that Bob Russell was a passenger on
+the Limited leaving the next morning. He was just twenty-four hours
+behind in the race, but he meant, if he could, to execute his
+orders, and was already smiling delightedly in anticipation of what
+he knew would be a contest of wits.

+<h3>
+CHAPTER VIII
+</h3>
+
+<h3>
+THE HOSPITALITY OF NEW MEXICO
+</h3>
+
+<p>
+Clarkeville was even smaller than the boys had imagined it. The
+little depot was far more pretentious than any other building in
+sight. Beyond this was a wide and exceedingly dusty street. On the
+far side of this unpaved roadway was a row of one- and two-story
+frame buildings. Here and there was a cheaper structure of little
+else but corrugated iron sheets, while to the left, where a similar
+street crossed the railroad at right angles, there was a one-story
+cement building proudly labeled "Bank." Both streets suddenly
+disappeared in a sandy, treeless plain.
+</p>
+
+<p>
+Wooden awnings in front of the buildings extended over the sidewalk.
+At the edge of these awnings were a few teams and many saddled
+horses, some of them hitched to posts, and others standing with their
+bridle reins dropped to the ground. Not many persons were in sight.
+The deep and cloudless blue sky was brilliant with the noonday sun
+while a hot breezeless haze hung over all.
+</p>
+
+<p>
+The Limited had made its usual daily pause and then to the surprise
+of the agent had run down beyond the water tank with one car,
+switched it back onto the one siding until it stood opposite the
+musty smelling freight shed, and, quickly coupling up again, had
+gone.
+</p>
+
+<p>
+Ned and Alan had alighted when the train stopped. Around them the
+boys could detect the first signs of the real West. At one end of
+the station a big-hatted Mexican squatted by a hot tamale can.
+Among others idling near were some high-heeled and sombrero-topped
+cow-boys, whose easy and loose clothing made Alan envious at once.
+Even the depot attendants, with their belts and loosely knotted
+neckerchiefs, seemed gayer and freer than their brother laborers
+back in the East.
+</p>
+
+<p>
+With coats off and collars loosened the two boys filled their lungs
+with the tonic air, for, in spite of the heat, a certain dryness
+seemed to give life and vigor to the atmosphere.
+</p>
+
+<p>
+"There it is, Alan," exclaimed Ned finally, pointing away to the
+north and the distant mountains, "beyond those peaks and somewhere
+under that sapphire sky is our land of promise. We'll be in it in a
+few days."
+</p>
+
+<p>
+The brilliant sky, the exhilarating air and the new life about them
+filled both boys with enthusiasm.
+</p>
+
+<p>
+"Whoopee!" almost shouted Alan finally, throwing out his arms as if
+to embrace his friend. "All we need is an Indian or two and I guess
+we'd be out West for sure."
+</p>
+
+<p>
+"You may not be so anxious to see them before we start back,"
+remarked Ned. "Anyway, I promise you enough of them in this
+country."
+</p>
+
+<p>
+With the departure of the train, the two boys became the center of
+some attention. Strangers were not plentiful in Clarkeville, and
+when the news spread that a special car was standing behind the
+freight shed on the far side of the tracks there was an instant rush
+of idlers in that direction. Ned and Alan returned with them and
+smiling good-naturedly right and left took stand at the forward car
+steps.
+</p>
+
+<p>
+It was about two o'clock in the afternoon, but so anxious had the
+boys become in the last stage of their journey that they had ordered
+Elmer to put off the noonday meal until they reached Clarkeville.
+The colored boy, troubled over the notion of a good dinner spoiling,
+was waiting on the car platform for it chance to get his "bosses,"
+as he delighted to call them, into the car.
+</p>
+
+<p>
+Before he could do so, and while the two chums were answering idle
+questions as to whether they were a "show," Ned's quick eye caught
+sight of a more important personage. A middle-aged man, not quite
+so western in appearance as the others, but plainly as much at home
+in the saddle, rode up with a clatter and sprang from his pony.
+</p>
+
+<p>
+Ned advanced quickly, spurred on by the new arrival's quick "Howdy,
+strangers!"
+</p>
+
+<p>
+"My name is Ned Napier," explained the lad, "and this is my friend,
+Alan Hope."
+</p>
+
+<p>
+The rider held out his hand.
+</p>
+
+<p>
+"I'm Curt Bradley, and I'm the mayor of this town," he replied by
+way of introduction.
+</p>
+
+<p>
+"Glad to meet you," answered Ned. "You've just saved me the trouble
+of looking you up, for that would have been my first business."
+</p>
+
+<p>
+"Not to be over cur'ous," laughed the Mayor as his eyes took in the
+big expensive car and then returned to the two boys, "might I
+inquire the nature o' yer business."
+</p>
+
+<p>
+Ned laughed.
+</p>
+
+<p>
+"Certainly," he answered, "but come aboard first. Elmer," he said
+to the waiting cook, waiter and porter, "another plate for Mr.
+Bradley."
+</p>
+
+<p>
+And in spite of the wholesome-looking but bronzed Mr. Bradley's
+protest that gentleman was soon sitting with the boys before what
+was perhaps the most elaborate meal he had ever eaten. His protest
+came from the fact that he had already had his dinner, but the fresh
+fruit and vegetables and spring chicken were temptations too strong
+for him.
+</p>
+
+<p>
+When Ned saw that their new acquaintance was at his ease and rapidly
+becoming satisfied he lost no time in coming to the point.
+</p>
+
+<p>
+"Our visit here, Mr. Bradley, is, in part, a secret. I hope you
+will accept my assurance, however, that it can in no way operate
+against or damage your town or its residents or the country round
+about. I want your assistance."
+</p>
+
+<p>
+"Ye can hev that," came the quick answer, "and if your lay is no
+one's business, why, it ain't none o' ours."
+</p>
+
+<p>
+"I'm glad to hear that," answered Ned. "But there may be some who
+will not be so considerate."
+</p>
+
+<p>
+"When I pass the word I guess they'll all think about like me,"
+interrupted the Clarkeville official. "Ye jest tell me what it is
+you want."
+</p>
+
+<p>
+"First I'll explain to you that in the other part of this car we
+have the material to make a dirigible balloon."
+</p>
+
+<p>
+"A what!" exclaimed the Mayor, his mouth full of chicken.
+</p>
+
+<p>
+"A balloon that you can guide through the air."
+</p>
+
+<p>
+Curt Bradley dropped his knife.
+</p>
+
+<p>
+"One o' them flyin' machines?"
+</p>
+
+<p>
+"Exactly."
+</p>
+
+<p>
+"And kin we all see it fly?"
+</p>
+
+<p>
+"Certainly," answered Ned, "if you will just see that no one
+interferes with us. I shall be glad in time to show you, I hope,
+the most perfect dirigible balloon ever put together and to explain
+just how it is to be operated. But in a few days, when it is ready,
+we are going to sail away on business that is our own. And when
+that time comes curiosity must stop. If anyone attempts to
+ascertain where we are going or what we mean to do I sound warning
+now that we will do all we can to prove to him that it is none of
+his business."
+</p>
+
+<p>
+The Mayor looked at them in surprise.
+</p>
+
+<p>
+"Why," he began, "I suppose ye must be on a mighty partic'lar job.
+Are you&mdash;?"
+</p>
+
+<p>
+"There!" interrupted Ned. "You see you are beginning to ask
+questions. Since we can't answer them we'd rather not hear them."
+</p>
+
+<p>
+"Right," exclaimed the Mayor. "Give me yer word it's all fair and
+square and that ye ain't violatin' no laws and I'll give ye my word
+they won't be no more questions asked."
+</p>
+
+<p>
+"I'm glad to do that," answered Ned, "we want certain accommodations
+for which we are willing to pay. But we want the confidence of
+Clarkeville that we are all right, even if we are a little young."
+</p>
+
+<p>
+"Clarkeville is yours," laughed the Mayor, getting up from the
+table, "and now what do ye want first?"
+</p>
+
+<p>
+In another hour the two boys, guided by Mayor Bradley, had examined
+the entire settlement. A little way down the railroad track they
+found a rather ramshackle building, mostly tin roof, and behind it a
+large plot of ground surrounded with a high corral or fence. The
+sign read "Buck's Corral." In the East it would have been called a
+livery stable. The air navigators engaged the place at five dollars
+a day for a week or more, and put a half dozen Mexican laborers at
+work removing the few horses and cleaning out the building and
+corral. The proprietor, who owned one of the few wagons in the
+town, they also hired as a drayman at $2.50 a day for himself and
+team.
+</p>
+
+<p>
+Work began at once. Through Mayor Bradley three reliable men were
+employed as watchmen, and these, in eight-hour shifts, undertook the
+duty of seeing that nothing in the corral was molested in the
+absence of Ned and Alan. Then the work of transporting material
+began, the first task being the removal of the five large generating
+tanks.
+</p>
+
+<p>
+Alan had been thoughtful enough to foresee the need of special
+clothing, and it was not long before he and Ned and even Elmer
+Grissom were enjoying the freedom of wide-brimmed hats, stout
+shirts, thick-soled shoes, and belts. Elmer's duty was the constant
+care of the Placida, which he only left on special permission. Ned
+and Alan were free to devote themselves wholly to the agreeable and
+long anticipated task of at last "getting ready."
+</p>
+
+<p>
+Help was easily hired and with Buck's wagon in service the
+wide-opened doors of the baggage car seemed to give out more boxes,
+crates and bundles than a full freight car. When strangers were on
+the car the colored boy stood like a sentinel over the black case
+which was made less conspicuous by being covered with a blanket.
+And his constant injunction "No smokin', sah," soon won him a
+sobriquet, Mexicans and cow-boys alike calling him "Smoky."
+</p>
+
+<p>
+Elmer was relieved from picket duty in time to prepare an extra
+supper to which Mayor Bradley, Buck, and Jack Jellup, the town
+marshal, were invited. It was extra work for "Smoky," who took his
+new name with a mild protest; but when he called the crew to the
+meal it was apparent that he harbored no resentment. Jack and Buck
+took their seats gingerly, but the boys soon made all at home.
+</p>
+
+<p>
+"There ain't agoin' to be no pay took fur this day's work," suddenly
+exclaimed Buck as he finished a generous portion of cold sliced ham
+and potato salad.
+</p>
+
+<p>
+The boys laughed in protest.
+</p>
+
+<p>
+"I ain't seen real food in ten years," continued Buck, "and what I
+said goes. This meal's worth a week's work to me."
+</p>
+
+<p>
+"All I got to say, young uns," interrupted Jack Jellup, the marshal,
+"is that this 'ere town is yours."
+</p>
+
+<p>
+Jack's idea of hospitality was an invitation to the boys to visit
+the town saloons as his guest, but Ned arid Alan laughed and thanked
+him, pleading weariness as a reason for declining. The final
+tribute of the three guests, however, before they left, was to push
+the Placida along with crowbars until it was free of the freight
+house and stood where the evening breeze could freely find its way
+through the windows. Then with hearty "buenos noches," ("Good
+night") and promises to see that every one was on hand early in the
+morning, they left.
+</p>
+
+<p>
+For some time Ned, Alan and Elmer sat in camp chairs on the car
+platform reveling in the glorious starlit night. From somewhere in
+the little town came the sound of low singing and a Spanish air
+played on the mandolin. It was all so different from the life the
+boys had known that it seemed like a dream. And when their real
+dreams did come it was of the not far distant Tunit Chas.

+<h3>
+CHAPTER IX
+</h3>
+
+<h3>
+"CALIFORNY KID" GETS A JOB
+</h3>
+
+<p>
+Old Buck's horse-corral had blossomed over night into a modern
+balloon factory. And the proprietor, with his bronco team, and the
+superintending Ned and Alan made big gaps the next day in the
+precious freight of the Placida. By noon the five casks for
+generating hydrogen, the cooling and purifying box, and the lead
+pipe and other equipment, had been transferred to the old horse
+yard. Three tons of iron turnings, forwarded by freight in advance,
+were found in the keeping of the railroad agent. It took Buck six
+trips to move this, and that consumed the afternoon.
+</p>
+
+<p>
+A special trip was made by the wagon just after luncheon. This was
+to transport the tool chest&mdash;practically two chests, for it was a
+large one containing both wood and iron-working tools. With it rode
+the two boys, both in overalls and ready to begin the setting up and
+adjustment of the generating tanks.
+</p>
+
+<p>
+After their arrival at the corral, the rest of the afternoon, in
+spite of the heat, slipped quickly away. But by night a foundation
+had been leveled in a corner of the yard and the five barrel-like
+generators were firmly anchored and connected by lead pipes with the
+cooling and purifying box.
+</p>
+
+<p>
+"Looks purty much like a distillery," commented Buck, who had just
+made his last trip with the iron shavings, which were now piled
+close by the casks.
+</p>
+
+<p>
+"And is," laughed Ned, "in a way."
+</p>
+
+<p>
+But he volunteered no more. In fact the whole matter was a mystery
+to every one in the town, except Mayor Curt Bradley and Marshal Jack
+Jellup.
+</p>
+
+<p>
+In the morning the first work accomplished was the removal, one at a
+time, of ten casks of sulphuric acid, each weighing four hundred
+pounds. It was a delicate job and not unattended with danger in
+case of a cask breaking. The boys began to realize the need of help
+of a higher grade than that of the "greasers" who had been thus far
+their only assistants except Buck.
+</p>
+
+<p>
+Their usual good luck seemed to be with them, however, for just in
+the middle of the work of sliding a heavy carboy of acid from the
+wagon a stranger stepped from the group of onlookers, and without
+words gave a hand to the job.
+</p>
+
+<p>
+Alan was about to thank him hurriedly, when the stranger said:
+"Wot's the game, son? Wot's doin'?"
+</p>
+
+<p>
+Alan was at first inclined to resent this "tough" familiarity. Then
+he realized that the language of the man was in his natural manner
+of speaking, and he said:
+</p>
+
+<p>
+"Who are you and where are you from?"
+</p>
+
+<p>
+"Give you one guess," laughed the stranger. "No! Can't tell a
+'bo'? Well, just tramp. Wot's dew name? I lost me card case. Me
+nom de plumb is Kid, Californy Kid. And me address is&mdash;well wot's
+de name o' dis munificent metropolis?"
+</p>
+
+<p>
+"Clarkeville, New Mexico," answered Alan smiling.
+</p>
+
+<p>
+"Well, den me address is dat. Wot's de nex' inquiry?"
+</p>
+
+<p>
+The man was young. His clothing was worn and greasy, his shoes were
+patched, and those parts of his face and hands that could be seen
+between smears of coal dust were red from exposure and the sun.
+</p>
+
+<p>
+"How do you happen to be here?" continued Alan.
+</p>
+
+<p>
+"Well, cul&mdash;beg pardon, son&mdash;de fact is I lost me purse and de
+brakeman on de fast freight wouldn't take me check. I was dumped.
+And I can't get away exceptin' I walk."
+</p>
+
+<p>
+"Then you wouldn't care to work?"
+</p>
+
+<p>
+"Will dis beautiful city give me coin and chuck widout work?"
+</p>
+
+<p>
+"I'm afraid not," laughed Alan.
+</p>
+
+<p>
+"Den' it's work for yours truly," answered the tramp with a sort of
+cheery humor. "But, say, boss, ye couldn't stake me to a drink and
+some chuck afore I loosen up me muscles?"
+</p>
+
+<p>
+"Your pay will be two dollars a day," said Alan, "but no drinking
+goes. Here's a note that will get you something to eat." And
+writing a message to Elmer the tramp was soon hurrying to the car
+for a meal. A half hour later, with his sleeves rolled up, he
+returned, riding alongside Buck on the wagon.
+</p>
+
+<p>
+Ned had given the new hand little attention.
+</p>
+
+<p>
+Now he looked him over and asked:
+</p>
+
+<p>
+"What's your real name?"
+</p>
+
+<p>
+"Gus, boss; or, spellin' it out, Gustave Lippe. How's dat for a
+handle&mdash;Lippe?"
+</p>
+
+<p>
+Ned looked at the young man long and sharply.
+</p>
+
+<p>
+"One name, they say, is as good as another out here. But I didn't
+know tramps got this far west."
+</p>
+
+<p>
+"Sure," answered the tramp, "It's long jumps and hard ones. It's me
+last excursion dis way."
+</p>
+
+<p>
+"Well," said Ned slowly, "you can work for us as long as you are not
+too inquisitive."
+</p>
+
+<p>
+"Dat's me, boss. I'm de clam till me two dollars per will git me to
+de next whistle."
+</p>
+
+<p>
+"Then you'd better arrange to board with Buck."
+</p>
+
+<p>
+"Dat's me lay, boss, already booked. Now show me some work. Me
+trunk was checked t'roo and I ain't nuttin' on me mind but me job."
+</p>
+
+<p>
+"Well, you had better spend the rest of the afternoon in cleaning up
+a bit," suggested Ned. "Here's five dollars in advance. Report
+early in the morning."
+</p>
+
+<p>
+"Tank's, boss," said Gus, the tramp. But he took the bill slowly.
+</p>
+
+<p>
+"But, you can't spend it on beer and whisky and work for us," added
+Ned.
+</p>
+
+<p>
+Gus shifted uneasily.
+</p>
+
+<p>
+"You'd better have a bath and a shave. And if you need clothes and
+can get them here," continued Ned, "I'll advance more to-morrow&mdash;if
+you show up all right."
+</p>
+
+<p>
+"I kin work widdout a shave," the man said, "ain't der nuttin' doin'
+to-day?"
+</p>
+
+<p>
+Assured that to-morrow was when he was wanted the tramp slowly and
+apparently reluctantly turned and slouched away toward the stores.
+</p>
+
+<p>
+"What do you make of him, Ned?" asked Alan as the two toys resumed
+work.
+</p>
+
+<p>
+"Too slangy, I think," commented Ned.
+</p>
+
+<p>
+But the final stowing of the acid soon drove the tramp from the
+minds of the boys.
+</p>
+
+<p>
+When the young aeronauts finally closed the corral and returned to
+the car, the sun a great red ball, was just dropping behind the
+serrated mountains of the western horizon. On the car steps, Ned
+turned and pointed to the north. Far away the dusky gray of the
+plains deepened into darker and darker shadows that ended in a low
+black mass. But here and there from the black wall rose irregular
+spires, their tops pink-tipped by the red sun.
+</p>
+
+<p>
+"Yes," exclaimed Alan, "the Tunit Chas&mdash;our mountains."
+</p>
+
+<p>
+And even though the vigilant Elmer called from within, the boys
+stood and gazed in silence until the last glow had died away and the
+land of their hopes was lost under the stars.
+</p>
+
+<p>
+Important as was the work to be done in Buck's corral, there was
+another vital thing to be accomplished while this progressed. That
+was the creation of a base of supplies near the navigator's field of
+work. This was preferably to be at the junction of the Amarilla and
+Chusco rivers, and that point lay just eighty-five miles to the
+north. Between Clarkeville and that spot there were no roads and,
+at this time of the year, perhaps, no water. With the best wagon
+and team they might be able to get, this trip over the desert would
+require not less than five days.
+</p>
+
+<p>
+It was impossible for either of the boys to go on this important
+errand, as both were needed on the spot to set up the balloon. So
+it had long since been decided that Elmer was to have charge of this
+secondary expedition. And since it was Elmer who would have to
+conduct the expedition safely to its destination and establish a
+relief camp, the colored boy had been thoroughly coached in his
+coming task.
+</p>
+
+<p>
+"Kin I?" the boy had said more than once. "When de Cibola gits dar
+I'll be dar. And ain't no Indians nor rattlesnakes nor hot weather
+goin' to break up dat camp."
+</p>
+
+<p>
+And the camp meant gasoline, water, food and a stepping stone back
+to civilization, whether the expedition ended in failure or success.
+As the boys had already planned that Buck should furnish the wagon
+and horses and guide Elmer's caravan, they had asked him to call
+that evening to talk it over.
+</p>
+
+<p>
+"I'm ready to start, yes, right now," Elmer had said as he served
+the good supper over which he had been laboring, "but I does jes
+nach'elly hate to turn you young gemmen over to dese greaser cooks."
+</p>
+
+<p>
+The boys laughed. "You don't think we can keep this up all summer,
+do you?" exclaimed, Ned. "Even 'greaser' cooks are better than
+having nothing to eat. And up there," nodding toward the north,
+"there won't be any cooks."
+</p>
+
+<p>
+"Don't forget," interrupted Elmer, "camp&mdash;camp&mdash;well, my camp. When
+you get dar dar'll be a good meal waitin' you and when you git outen
+de mountains I'll still be dar waitin' wid eatin's."
+</p>
+
+<p>
+The boys laughed again.
+</p>
+
+<p>
+"Like as not," suggested Alan, "if you get all that truck up there.
+You'll certainly have enough. But don't you bother about the eating.
+You just watch the water and the gasoline."
+</p>
+
+<p>
+"Till de snow flies," exclaimed Elmer with emphasis.
+</p>
+
+<p>
+"Which, right there," dryly remarked Ned as he disposed of the last
+of a generous slice of melon, "is rather indefinite."
+</p>
+
+<p>
+When Buck, whose real name they had discovered to be William
+Bourke&mdash;easily corrupted into "Buck"&mdash;appeared, the boys had a delicate
+job before them. Inquiry had quickly shown them that Buck's twenty-five
+years on the old Santa Fe trail as guide and an active service in the
+army as scout easily made him the man to conduct Elmer to the north.
+</p>
+
+<p>
+To all their long explanations and reasons Buck listened in silence.
+When there seemed nothing more to be said, Buck smothered the still
+glowing end of a cigarette between his dark weather-beaten fingers
+and said slowly:
+</p>
+
+<p>
+"When do we start?"
+</p>
+
+<p>
+It was arranged that on the second morning Buck should be ready for
+a journey of uncertain length; that the general direction should be
+north; that the final destination should be revealed by Elmer on the
+second morning out.
+</p>
+
+<p>
+"Soldier-like," Buck had commented, "and that's the way I like it."
+</p>
+
+<p>
+Buck and an assistant were to take an outfit of two wagons, each
+drawn by four horses. In the lighter wagon six barrels of water
+were to be carried for use in case the usual "water holes" were dry.
+In case of an accident, the lighter wagon and horses were to be sent
+south by the second man and Elmer and Buck were to make a quick dash
+forward with what water and supplies could be carried on the other
+wagon.
+</p>
+
+<p>
+Old Buck made rather light of the matter.
+</p>
+
+<p>
+"Injuns ain't nothin' nowadays," he had explained, shrugging his
+shoulders, "ye jest want to keep yer bearin's and git used to
+drinkin' atmosphere and ye'r all right."
+</p>
+
+<p>
+The contract with Buck called for thirty dollars a day in money and
+food for himself and a helper. Both parties to the contract were
+satisfied and after Buck's fresh cigarette disappeared in the
+direction of the town the boys lost no time in turning in for a good
+night's rest.

+<h3>
+CHAPTER X
+</h3>
+
+<h3>
+AN ERROR IN CALCULATION
+</h3>
+
+<p>
+While Buck was busy getting his wagons and horses and water casks
+ready the next morning the boys were not surprised to see Gus, the
+tramp, drive up just after breakfast with the moving team.
+</p>
+
+<p>
+"Have you had breakfast?" asked Alan by way of a greeting.
+</p>
+
+<p>
+"Have," retorted Gus, pulling up his team awkwardly. "It's me
+wrappin' meself around tortillas till I feel like a bag o' corn
+meal."
+</p>
+
+<p>
+"I can't see that you've spent any great amount of that five dollars
+on yourself," interrupted Ned, noticing the tramp's unshaven face
+and the still visible traces of coal smoke.
+</p>
+
+<p>
+"Well, boss, ye'r right. Dead right. But, ye see, de barber o' dis
+growin' city only works on Saturday and me friend Buck's bat' tub
+has a leak. Anyhow, de ladies hereabouts is scarce and few. Think
+wot a swell I'll be when Sunday comes."
+</p>
+
+<p>
+"Come in the car. We've plenty of water, and soap too," suggested
+Alan, smiling.
+</p>
+
+<p>
+'"Well, boss, don't tempt me. I'm working. I can't soldier away no
+time dudin' meself up on do bosses' time."
+</p>
+
+<p>
+"All right," replied Ned, laughing, "every one to his taste."
+</p>
+
+<p>
+There was plenty of work to be done, and in a few minutes all were
+at it. The chief task this day was the unloading of the materials
+yet on the car. That had to be done by night, except in the case of
+the boxes marked "Overland," all of which had been carefully and
+specially crated for wagon transportation. Of these there seemed a
+great many, and they were all put in one pile in the space made
+vacant by the removal of the gas generators. The hydrogen case,
+covered with a blanket, stood always under Elmer's watchful eye.
+This was to be removed last.
+</p>
+
+<p>
+As the boys meant to stay close by their valuable outfit, they
+planned to load Elmer's caravan early the next morning and to see it
+start on its trying and dangerous trip. Then they intended to
+remove the hydrogen cask to the corral and take up their own abode
+in the same place. The Placida&mdash;with no little regret&mdash;was to be
+surrendered to the railroad and returned to Chicago.
+</p>
+
+<p>
+For that reason this was a busy day. Load after load of crates,
+boxes, and bundles were carried to the big corral, the teams
+stirring up the dust of Clarkeville's main street on their way. It
+was heavy work, and required care. Smoky-faced Gus was earning his
+pay. So skilful and adroit was he in executing tasks assigned him
+that Ned commented on it to Alan.
+</p>
+
+<p>
+While the boys were at their noonday lunch Buck appeared to report
+progress. The big wagon was to come from a sheep ranch, ten miles
+to the south. A man had gone for it and would arrive with it that
+night. The wheels of the smaller wagon were being soaked in water
+and the axles had been greased.
+</p>
+
+<p>
+Ned could not resist asking:
+</p>
+
+<p>
+"How's your new boarder, Buck?"
+</p>
+
+<p>
+"Ain't seen much o' him. Purty poor feeder fur a tramp. Can't get
+a tortilla down him nohow."
+</p>
+
+<p>
+Ned looked at Alan significantly.
+</p>
+
+<p>
+"Hasn't any baggage, has he?" continued Ned.
+</p>
+
+<p>
+"Not a stitch. Lessen you allow fur a extra suit o' underclothes."
+</p>
+
+<p>
+"Under clothing?" exclaimed Ned. "Two suits?"
+</p>
+
+<p>
+"Yep. And fine, too. My old woman washed a suit to-day and she
+'lows as how it cost more than the rest o' his outfit."
+</p>
+
+<p>
+"Don't you think that funny?"
+</p>
+
+<p>
+"'What?" responded Alan sleepily.
+</p>
+
+<p>
+"Why, a tramp with two suits of fine underwear?"
+</p>
+
+<p>
+"Probably he stole them."
+</p>
+
+<p>
+"And probably he didn't. A real tramp might steal them, but he
+wouldn't wear them."
+</p>
+
+<p>
+"Well, what do you care," laughed Alan, "whether he's a tramp or not
+so long as he's useful?"
+</p>
+
+<p>
+Ned was silent a few moments.
+</p>
+
+<p>
+"Tramp or not, that fellow will bear watching."
+</p>
+
+<p>
+"All right," conceded Alan, "I guess we can do that."
+</p>
+
+<p>
+By night the barn and horse yard of the corral looked like a
+combination manufactory and hardware store. The seven sections of
+the skeleton-like car stretched across the old horse yard like a
+disjointed snake; crated aeroplane guides, and the propeller and the
+rudder leaned against the fence, looking like the frame work of a
+house; the more compact engine, motor, radiator and fan stood ready
+for unpacking under the shelter shed, while shafts, connections and
+boxes of small parts filled a large part of the empty stalls. The
+tins of gasoline for experimental flights and the first trip to
+Elmer's camp were in a far corner of the yard, and in the wagon shed
+stood the two immense special trunks containing the gas bag and the
+Italian hemp netting.
+</p>
+
+<p>
+The evening meal was not as cheery and chatty an affair as the
+preceding ones had been, although Elmer had done his best in honor
+of their farewell. And the boys insisted that at this last meal the
+waiter should be dispensed with, and Elmer was put at the head of
+the table.
+</p>
+
+<p>
+"Yo' make me feel as if I was a startin' fo' do norf pole,"
+exclaimed Elmer. "I don't see what's de use of so much fussin'."
+</p>
+
+<p>
+"Well, anyway," exclaimed Ned, holding up a glass of iced tea,
+"here's luck to you, Elmer."
+</p>
+
+<p>
+"And de same to you," answered Elmer. "And to all of us."
+</p>
+
+<p>
+Rising bell was to ring at four o'clock the next morning; so the
+boys all turned in at once after they had cleaned up the kitchen.
+</p>
+
+<p>
+It was about twelve o'clock when a sudden call sounded through the
+car.
+</p>
+
+<p>
+"Alan!".
+</p>
+
+<p>
+It was Ned, who, clad in pajamas, was shaking his chum. The latter,
+dazed for a moment, sprang upright, soundly whacking his head on the
+upper berth, in which Elmer was snoring loudly.
+</p>
+
+<p>
+"What is it?" he exclaimed, rolling out on the floor. "Who hit me?
+Indians?"
+</p>
+
+<p>
+"Not yet," laughed Ned, shaking his "pal" into wakefulness.
+"Listen!"
+</p>
+
+<p>
+He struck a match, lit a candle and sat down on the edge of the
+berth.
+</p>
+
+<p>
+"You're a bum calculator," he began, eyeing Alan.
+</p>
+
+<p>
+"I didn't calculate where that berth was," answered Alan ruefully,
+rubbing a lump on the top of his head.
+</p>
+
+<p>
+"And you didn't calculate where we are now," somewhat excitedly
+added Ned. "And I didn't think of it until just now."
+</p>
+
+<p>
+"Go on," interrupted the still sleepy Alan. "If it's a riddle I
+give it up."
+</p>
+
+<p>
+"I suppose you know what the air pressure is to a square inch,"
+answered Ned, like a school teacher rebuking a slow scholar.
+</p>
+
+<p>
+"Why, 14.7 pounds, of course."
+</p>
+
+<p>
+"Where?" exclaimed Ned again, sharply.
+</p>
+
+<p>
+"Where?" echoed Alan.
+</p>
+
+<p>
+"Why, at the sea level-that's where. Not out here. Do you know how
+high we are above sea level right here?"
+</p>
+
+<p>
+Alan began to see the point and a smile came over his face. He had
+no chance to answer:
+</p>
+
+<p>
+"We're a little short of seven thousand feet up in the air right
+here in Clarkeville," continued Ned in about the same tone of
+exultation he might have used had he found a gold mine. "Now,
+listen. How many cubic feet of gas does our balloon hold?"
+</p>
+
+<p>
+That question was easy. The boys knew that as well as the
+multiplication table.
+</p>
+
+<p>
+"Sixty-five thousand, four hundred and ninety-three feet."
+</p>
+
+<p>
+"And how much weight is it going to carry?"
+</p>
+
+<p>
+"Three thousand nine hundred and thirty-five and a half pounds."
+</p>
+
+<p>
+"Exactly," went on Ned. "That's the weight we are going to carry
+figured at sea level. Did it ever occur to you that our sixty-five
+hundred feet of hydrogen can lift more way up here seven thousand
+feet in the air, than it can at sea level? Did it ever occur to my
+special engineer and calculator that as the weight and pressure of
+the air grows less our hydrogen will lift just that much more
+weight.
+</p>
+
+<p>
+"By the great horn spoon!" exclaimed Alan. "Give me that candle."
+</p>
+
+<p>
+In another moment he was at the drawing room table with a pencil in
+his hand. It did not take him long to make his calculations.
+</p>
+
+<p>
+"Live and learn," he exclaimed finally. "I'm certainly all you said
+was a 'bum calculator.' Our altitude here is 6,875 feet, for I took
+it to-day just for practice. And we can carry in our balloon just
+exactly 693.6 pounds more than we figured."
+</p>
+
+<p>
+"I thought so," laughed Ned. "It came to me in a dream, I guess.
+But you don't need to feel badly. You say I'm the boss, yet I never
+thought of it. You see, the trouble is that all the balloon
+ascensions ordinarily are made from the large cities of America or
+Europe. Who ever thought of ascending a mountain to get a start?
+But since we have done so we must figure accordingly."
+</p>
+
+<p>
+"And what is the first thing you are going to add?" asked Alan.
+</p>
+
+<p>
+"First thing?" exclaimed Ned. "First and last and in the middle,
+gasoline. We may find water in the mountains and we might even find
+food, but we're not going to find gasoline. Now we'll do part of
+our work whether Elmer meets us or fails."
+</p>
+
+<p>
+The incident showed the essential difference between Ned's mind and
+Alan's. Alan was careful, precise, and adept in detail. Ned had
+the "dreams" and inspirations of an inventor.

+<h3>
+CHAPTER XI
+</h3>
+
+<h3>
+A DISGUISE PENETRATED
+</h3>
+
+<p>
+The boys, in spite of their broken slumbers, all turned out promptly
+at four o'clock the next morning. They found this hour the
+pleasantest of the day in this hot and dry region. The late moon
+was just disappearing, and over the plains swept a breeze that
+hinted of snow on some mountain peak not far away. Not a sound
+broke the stillness but the occasional cry of a skulking coyote.
+</p>
+
+<p>
+"Hear it, Elmer," said Alan, as the boys got busy in the baggage
+car. "You want to look out for those fellows."
+</p>
+
+<p>
+"I ain't feared o' no cutes and I ain't feared of no Injun,"
+solemnly answered Elmer, "jist so dem rattlers gives me de go-by.
+Dat's all I ast."
+</p>
+
+<p>
+Buck's big wagon had arrived and was backed up to the car and now,
+by the light of a lantern hanging above the door, the work of
+loading began.
+</p>
+
+<p>
+With their improved gas bag the boys had figured on a record flight
+without renewing the gas supply. They had hoped to be able to stay
+at least seventy-two hours in the air. But during a large part of
+this time they expected to drift without the engines, for they could
+not carry enough gasoline to last for more than twenty-four hours of
+engine work. By their new calculations they had more than enough
+gasoline, and according to Ned it seemed probable that the decreased
+air pressure on the bag might extend the period of flight another
+twenty-four hours, or to four days.
+</p>
+
+<p>
+After that all would depend on the liquid hydrogen. The remarkable
+qualities of this unique product were to be tested for the first
+time in the history of ballooning. When the gas in the bag had
+diminished by leakage through the valves and elsewhere so that it
+was no longer sufficient to carry the car, the liquid hydrogen was
+to be turned into gas which was to take the place of that lost. Ned
+had left Washington with sixteen cubic feet of the liquid in eight
+delicate Dewar bulbs, or casks. He figured that one-quarter of it
+would be lost by evaporation, leaving twelve cubic feet. This seems
+a small supply until one understands that the hydrogen increases in
+volume 880 times as it returns into gas from the liquid form. The
+twelve cubic feet of liquid, therefore, would give them a little
+over ten thousand cubic feet of new gas. And this, with the loss of
+ballast and provisions in three or four days, Ned calculated, would
+give the balloon a new life of a day or so.
+</p>
+
+<p>
+Therefore, the secret plan was a direct journey to Elmer's camp, a
+flight of eighty-five miles, which would bring the Cibola near to
+the foot of the mountains of mystery. After this camp had been
+located and more gasoline taken aboard the boys were to head their
+craft toward the Tunit Chas mountains. What would follow they could
+not foresee. With good luck they might be able to hover birdlike
+over the peaks, canyons and plateaus for five days. With bad luck
+they might have to come down sooner or fall. Then, if the Cibola
+failed them, they would have to find their way to the treasure
+temple and the ruined palace on foot in a rugged wilderness,
+infested with unfriendly Indians and reptiles, or struggle back, in
+some manner, if they could, to Elmer's relief station, and thus to
+civilization.
+</p>
+
+<p>
+Should the worst happen and the balloon fail them, the boys might be
+lost in a desolate region that is even now uncharted by the
+government. The only resources they would have would be the Cibola
+equipment and their own ability to take care of themselves. In any
+event, the knowledge that Elmer and Buck were in camp ready to
+succor them meant a good deal. And that was why the loading of the
+overland outfit had so much interest for the boys.
+</p>
+
+<p>
+Of tins of provisions there were many: condensed foods&mdash;German
+erbswurst, or army rations of ground peas and meat; dried potatoes;
+eggs in powdered form; preserved and salt meats; hard tack; tea and
+coffee; flour; and evaporated fruits. The water was already
+arranged for and the wagon containing the casks was at Buck's adobe
+house.
+</p>
+
+<p>
+On the floor of the wagon, packed in bunch grass, were the precious
+gasoline casks. On top of all came the silk waterproof tent and the
+camp equipage. Stowed under the seat was the box containing spare
+flags, a heliograph, part of a wireless telephone outfit (the other
+part was to be carried in the balloon) and compass. Two magazine
+rifles and ammunition were included in the outfit, and Elmer donned
+for the first time in his life a belt and holster to carry one of
+the magazine revolvers that Ned had bought on the day when he first
+told Alan what he had undertaken to do.
+</p>
+
+<p>
+By the time this work was done it was day. Then came breakfast,
+which Elmer insisted on preparing. He even demanded that he be
+given time to make hot biscuits. These, with thick slices of
+broiled ham, the last of their oranges, and hot fragrant coffee
+constituted the last meal on the Placida.
+</p>
+
+<p>
+As the meal came to an end the clump, clump of horses' feet in the
+sand announced that Buck had arrived and that it was time for
+breaking the "special car" camp. Alan and Elmer hastened to clean
+up the little kitchen that had given the boys so many savory meals
+and to pack up the remaining provisions, and Ned jumped off the car
+to see Buck.
+</p>
+
+<p>
+To the lad's surprise he found Gus, the tramp, just as dirty and
+just as cheerful as ever, proudly mounted on one of the newly
+arrived horses. Buck noticed the surprise in Ned's face and
+explained:
+</p>
+
+<p>
+"The helper I thought I could get fell down on me. My boarder's
+goin' with us. I guess he'll do."
+</p>
+
+<p>
+"You understand you don't know where you're going," said Ned,
+approaching Gus as he rolled off his horse, "nor when you're coming
+back?"
+</p>
+
+<p>
+"I knows dat we ride and dat dere's chuck a-plenty," smiled Gus,
+"and whichever way it is," he added lowering his voice and
+chuckling, "can't be no worse dan Buck's place&mdash;fur me."
+</p>
+
+<p>
+"Do you want to go?"
+</p>
+
+<p>
+"Well, I ain't a settin' up nights a longin' to, but to oblige a
+friend, Mr. Buck, I allowed meself to be persuaded."
+</p>
+
+<p>
+"Well, we'll see," said Ned.
+</p>
+
+<p>
+Ned rather wanted to watch this young man. Something suggested that
+the tramp was too quick witted to be made a party to their plans.
+Ned didn't exactly know what harm the stranger could do them, but he
+decided to talk it over with Alan. While Buck was hitching up the
+horses Ned turned to go into the car.
+</p>
+
+<p>
+They were loading from the far side opposite the hydrogen cask and
+as Ned passed the corner of the car he almost ran into the station
+agent. The agent, who was also the telegraph operator, had a
+telegram for Ned, which the boy took eagerly. Ned had sent a
+message to Major Honeywell, telling of their safe arrival, and did
+not doubt that this was some important afterthought of the Major's.
+The address ran: "Mr. Ned Napier, Private car Placida, Clarkeville,
+New Mexico." Tearing open the envelope Ned read:
+</p>
+
+<p>
+"Just learned Kansas City Comet has story mysterious trip for
+government starting Clarkeville. Real object not known. Look out
+not followed.
+</p>
+
+<p>
+"Baldwin Honeywell."
+</p>
+
+<p>
+With three jumps Ned was in the car and had pull Alan into the
+drawing room portion. The telegram was read again and the two boys
+looked at each other in astonishment.
+</p>
+
+<p>
+"How could they?" began Alan.
+</p>
+
+<p>
+"No matter how," answered Ned, almost out of breath. "They did and
+that's enough. Now I know!"
+</p>
+
+<p>
+"Know what?"
+</p>
+
+<p>
+Ned pushed his chum to the side of the car and pointed outside where
+Buck and his helper were at work.
+</p>
+
+<p>
+"Look at him," he exclaimed.
+</p>
+
+<p>
+"At Buck?"
+</p>
+
+<p>
+"No. At the tramp who won't wash his face, who has a gentleman's
+underclothes and who is so anxious to work for us!"
+</p>
+
+<p>
+"Well, I see him. But&mdash;"
+</p>
+
+<p>
+"Haven't you ever seen those sharp eyes before?"
+</p>
+
+<p>
+"You don't mean&mdash;?"
+</p>
+
+<p>
+"I do. If that isn't Bob Russell, the Comet reporter, I'm a goat."
+</p>

+<h3>
+CHAPTER XII
+</h3>
+
+<h3>
+NED TO BOB RUSSELL'S RESCUE
+</h3>
+
+<p>
+It was a time for quick and fast thinking, and Ned and Alan did it.
+Alan's instant suggestion that they denounce the disguised tramp was
+almost as quickly voted down.
+</p>
+
+<p>
+"So long as we didn't know who he was he had the advantage of us.
+Now that we know&mdash;" and neither of them now doubted the fact for an
+instant. "We have the advantage of him," argued Ned. "Let's turn
+that knowledge to profit. We can easily guess what he is trying to
+do. Major Honeywell's message says our real object is not known.
+This reporter has learned something, and I suspect he could have
+found quite a lot from the train crew. On that he has written a
+good enough story to attract attention. That shows he is no fool.
+And he wouldn't come out here unless he had been sent. Who would
+send him? Why, his paper, of course, to discover our real mission."
+</p>
+
+<p>
+"What can we do to head him off?" mused Alan.
+</p>
+
+<p>
+"There are two ways," suggested Ned, "and we've got to make one of
+them effective. I don't know how he has guessed but he must not
+have another guess. And he's seen a good deal."
+</p>
+
+<p>
+"We might have him arrested," suggested Alan.
+</p>
+
+<p>
+Ned thought awhile.
+</p>
+
+<p>
+"I'll tell you, Alan," he said finally. "The young men of the press
+to-day may write fanciful stories, and they may even 'fake' where it
+injures no one, but personally they won't lie. Let's call our tramp
+in here, confront him with his imposture and give him his choice of
+writing nothing or of being drummed out of town."
+</p>
+
+<p>
+"Who'll make him leave town?"
+</p>
+
+<p>
+"Marshal Jack Jellup wouldn't need two suggestions on that score.
+And more, he'd see that the order was obeyed. I don't like to do
+it, but I think we're justified. He's taking that chance."
+</p>
+
+<p>
+Again the thing was gone over, with arguments for and against, and
+then Elmer was hastily dispatched to find Jellup and bring him to
+the car.
+</p>
+
+<p>
+"And Buck will lose his helper," laughed Alan.
+</p>
+
+<p>
+"Better that than a second expedition on our heels," answered Ned
+</p>
+
+<p>
+"Gus!" he called, throwing open a window. "Come in here!"
+</p>
+
+<p>
+The tramp soon stood before them.
+</p>
+
+<p>
+"Geel Dis is a swell joint," were the tramp's first words as with
+apparent awkwardness he entered the car.
+</p>
+
+<p>
+Ned acted as spokesman.
+</p>
+
+<p>
+"You say you've promised Buck to go with him without knowing where
+you are going?"
+</p>
+
+<p>
+"Dat's about de cheese."
+</p>
+
+<p>
+"Well, we are willing. But I may as well tell you that this is a
+secret expedition. If you go you must promise that you will not
+tell anyone what you see or hear."
+</p>
+
+<p>
+The tramp's face suddenly took on a peculiar look, but it was gone
+as quickly.
+</p>
+
+<p>
+"I gives me woid. I won't open me trap to no one."
+</p>
+
+<p>
+"Meaning you won't say anything about it?" smiled Ned inquiringly.
+</p>
+
+<p>
+"Dat's it. Mum's de woid. I won't open me trap."
+</p>
+
+<p>
+"Nor write anything?"
+</p>
+
+<p>
+The furtive look came back, this time more pronounced.
+</p>
+
+<p>
+"Me to write! Wit wot? Me new typewriter?"
+</p>
+
+<p>
+"That isn't an answer. Do you promise, if we send you with Buck,
+that you'll neither tell nor write nor make known in any way what
+you learn about what we are doing?"
+</p>
+
+<p>
+"Say, look here, boss. Quit yer kiddin'. Me name is Lippe and
+mebbe I shoot it off a bit too frequent now and then, but you don't
+need to be afeered o' me peachin' to de udder'Bos.'"
+</p>
+
+<p>
+"I'm not afraid of that," continued Ned. "We don't care what you
+tell all the tramps this side of Kansas City. But we don't want you
+to print anything more about us in the Comet."
+</p>
+
+<p>
+Hardly a flush came on the tramp's face. There was a quick movement
+of the lips as if he were about to make protest and then he laughed
+outright.
+</p>
+
+<p>
+"Bob Russell," said Ned, also laughing, "would you like the use of
+our bath tub for a few moments?"
+</p>
+
+<p>
+"Would I!" laughed the young reporter rubbing his tinted and smoke
+begrimed hands together as if to wash them. "Well, I guess I would.
+My hands are up. What's next?"
+</p>
+
+<p>
+"Wash up and we'll see," exclaimed Ned.
+</p>
+
+<p>
+The young reporter was still laughing. "And if it isn't too much
+trouble," he asked, "would you mind if Buck took his check over to
+the depot and got the suit case that it calls for? Then we'll talk
+business."
+</p>
+
+<p>
+In less than twenty minutes the sun burnt, dirty Gus Lippe had been
+transformed into the dapper Bob Russell. When he reappeared in
+fresh linen, outing clothes and a natty straw hat, he was still
+laughing. Approaching the group in the drawing room, where Marshal
+Jack Jellup had now arrived, the young reporter took out his pocket
+book and a five dollar bill.
+</p>
+
+<p>
+"I'll pay that back first," he began; and then noticing one of his
+cards he politely handed it to the marshal. It read:
+</p>
+
+<p>
+ROBERT RUSSELL
+KANSAS CITY COMET
+</p>
+
+<p>
+"Ye'r a purty fresh kid," sneered Jellup.
+</p>
+
+<p>
+"At your service, Mr. Officer."
+</p>
+
+<p>
+Jellup had already received an explanation of the whole affair and
+was aching to exercise his authority.
+</p>
+
+<p>
+"Ye'r an impostor," he began, "and ef ye hadn't been caught, ye'd
+have taken money on false pretenses. I was onto ye."
+</p>
+
+<p>
+"Oh, now," interrupted Bob, "at two dollars Mex per day I'd have
+given good value."
+</p>
+
+<p>
+"Mebbe," retorted the marshal, "but these gentlemen hev come here on
+particular business and they came like gentlemen. The officials o'
+this city hev give their word that there shouldn't be no interferin'
+with their plans. And thet's what you're a-doin'. Now git!"
+</p>
+
+<p>
+Ned broke in:
+</p>
+
+<p>
+"One moment, Mr. Marshall"
+</p>
+
+<p>
+"Oh, that's all right, Mr. Napier," exclaimed the reporter, "he
+doesn't mean just that. He knows I don't have to leave here so long
+as I obey the law."
+</p>
+
+<p>
+"Ye don't, don't ye?" retorted the marshal. "Well, there ain't no
+back east law down here. Our law books mebbe got all burnt up. And
+mebbe I happen to be purty much o' the law myself. Ye'll git and
+git quick."
+</p>
+
+<p>
+Again Ned interfered.
+</p>
+
+<p>
+"I suppose if we ask you to permit Mr. Russell to stay here he can,"
+he asked.
+</p>
+
+<p>
+"Well, I reckon that would be so. Ef ye ask it I reckon I'll have
+to," he replied surlily.
+</p>
+
+<p>
+Ned and Alan held a brief consultation.
+</p>
+
+<p>
+"We have decided to ask the authorities to permit you to remain here
+on one condition."
+</p>
+
+<p>
+The intelligent face of Bob took on a quizzical air as he waited to
+hear the condition.
+</p>
+
+<p>
+"That is," went on Ned, "that you give us your word that you will
+not make known anything you have seen here, or of our plans so far
+as you may know them."
+</p>
+
+<p>
+Bob's answer was immediate.
+</p>
+
+<p>
+"I can't do that," he said, "I was sent here to do just that thing,
+and as quickly and as fully as I can. You ought to understand, and
+do, I think, that I have a duty to perform. I've taken the trouble
+to come all the way out here to get a story. I've got it and of
+course I'm going to use it. I should be false to my duty, to my
+employers and to myself if I promised not to do this."
+</p>
+
+<p>
+"But you don't know our story."
+</p>
+
+<p>
+"And I'm sorry. But I should have known it all if I had had a
+little better luck."
+</p>
+
+<p>
+"Then you won't promise?"
+</p>
+
+<p>
+"Decidedly not."
+</p>
+
+<p>
+The boys showed that they were as stubborn as he.
+</p>
+
+<p>
+"Then we'll see that you learn no more," Alan exclaimed angrily.
+</p>
+
+<p>
+Bob smiled. "You can't take away what I already know, and it will
+take a pretty long story to tell all I am going to guess from what I
+have seen."
+</p>
+
+<p>
+As he spoke his eyes were on Major Honeywell's chart of the Tunit
+Chas Mountains, which had carelessly been left lying on the table
+where it had been in use during breakfast in the last explanations
+to Elmer.
+</p>
+
+<p>
+Ned's face reddened in new anger. He did not resent what the young
+reporter was doing; he even realized that he might do the same thing
+himself; but he was chagrined to find himself caught in such a
+simple manner. That was a big piece of additional information for
+Russell to have, and Ned knew it. Hard as the thing was to do he
+would at least put the young man out of the way of further
+discoveries.
+</p>
+
+<p>
+"All right," he exclaimed, "we've tried to do the fair and decent
+thing, and if you want to be stubborn Marshal Jellup can do as he
+likes."
+</p>
+
+<p>
+"Git!"
+</p>
+
+<p>
+It was the marshal who spoke and he did so as if it were a pleasure.
+</p>
+
+<p>
+"I'll take the Limited west to Gallup at noon," said Russell, "if I
+can stop it and catch the eastbound train there to-night."
+</p>
+
+<p>
+"Then ye'll flag it along the road," shouted Jellup, "fur ye'll get
+out o' here on foot and in a hurry."
+</p>
+
+<p>
+"On foot?" exclaimed Russell in surprise.
+</p>
+
+<p>
+"That's what I said an' ye heerd me."
+</p>
+
+<p>
+Russell looked in appeal at the two boys.
+</p>
+
+<p>
+Ned was mad, and mad all over.
+</p>
+
+<p>
+"You are so quick to have your own way," he said, "you can't blame
+us."
+</p>
+
+<p>
+"All right," was the cheery response, "it'll lend a bit of local
+color to the story. Goodbye, boys. And good luck to you. I'll see
+you when you come back."
+</p>
+
+<p>
+"Remember," said Alan relenting a trifle, "we'll let you stay until
+we leave if you'll promise to write nothing."
+</p>
+
+<p>
+Bob laughed again.
+</p>
+
+<p>
+"What good would that do me? No experience means anything to me
+that I can't turn into copy. And as for walking&mdash;I'd walk from here
+to Kansas City or crawl before I'd lie down on my shop like that."
+</p>
+
+<p>
+"Come on, kid, get busy," exclaimed Jellup again. "An' when ye
+start, don't bother about lingerin', because I'll be hangin' around
+and I'm good with this at some distance."
+</p>
+
+<p>
+As he spoke he drew a Colt 44 and tapped it.
+</p>
+
+<p>
+"Never fear, Mr. Jellup," laughed Bob. "I suppose I can express my
+suit case to the next town?"
+</p>
+
+<p>
+"Ye can't do no business in this city, d'ye hear? Now, come on."
+</p>
+
+<p>
+"Say, partner," interrupted Bob with his usual good humor, "if you
+will let me take a snap of you I'll make you celebrated. 'Famous
+gun man' of New Mexico. It'll be great."
+</p>
+
+<p>
+In another moment the nettled marshal had Bob by the shoulder and
+was whirling him out of the car. On the steps he threw the suit
+case onto the sandy plain and then pushed the reporter roughly down
+the steps. Ned and Alan stood, with flushed faces, watching the
+reporter pick up his hat and suit case. Then young Russell made a
+remark they could not hear and the marshal's revolver flashed in the
+air. They could see the boy's face grow pale at last, but as he
+straightened up the two men disappeared around the freight house.
+</p>
+
+<p>
+Like a flash Ned was on the ground and after the marshal and his
+victim. Alan and Buck came running in the rear, for the alert Buck
+saw that something was in the air. It was early day and only a
+straggler or two was in sight at the depot. The sun, already
+mounting high, foretold a day of depressing heat. The steel lines
+of the railway stretched interminably eastward toward the first stop
+forty miles away.
+</p>
+
+<p>
+Bob Russell, pale but defiant, stood in the middle of the track, his
+heavy suit case in his hand.
+</p>
+
+<p>
+Suddenly there was the crack of a revolver and the dust flew about
+the young reporter's feet.
+</p>
+
+<p>
+"Jist as a sample!" roared the angered Jellup. "The next one'll be
+higher up." And his trembling finger pointed down the hot sandy
+track.
+</p>
+
+<p>
+There was nothing more to be done. The pale-faced but nervy
+reporter turned toward the east and started slowly down the track.
+</p>
+
+<p>
+Ned ran forward.
+</p>
+
+<p>
+"Russell!" he shouted, "Russell!"
+</p>
+
+<p>
+As the reporter paused and turned, hearing his name, there was a
+second report of the marshal's revolver and Russell's suit case flew
+from his hand, ripped and torn ragged by a forty-four bullet.
+</p>
+
+<p>
+The smoke of the explosion puffed upward and, where it had been, the
+marshal saw Ned Napier's automatic magazine revolver under his nose.
+</p>
+
+<p>
+The boy was white with indignation. The possible serious results
+that might come to him and his plans meant nothing in his anger at
+such a dastardly act.
+</p>
+
+<p>
+"It isn't a Colt," he said with dry lips, "but, if you make another
+move like that it's got ten shots and they come out all together."

+<h3>
+CHAPTER XIII
+</h3>
+
+<h3>
+QUICK JUSTICE IN THE WEST
+</h3>
+
+<p>
+Jack Jellup, marshal and "bad man," was never more surprised in his
+life. But Jack was no fool, and something in Ned Napier's eyes made
+the westerner conclude instantly that he had unexpectedly and
+unquestionably "barked up the wrong tree." For a few moments the
+marshal and the young aeronaut stood facing each other and then
+Jellup sneered:
+</p>
+
+<p>
+"Do you reckon you'd better run this town?"
+</p>
+
+<p>
+"No, nor you," quietly answered Ned, "and if that's the way you are
+going to do it you can settle with me right now. I'm going to stand
+on my rights."
+</p>
+
+<p>
+He was conscious that Russell had hurried back and was behind him.
+Another second and there was a sharp click. Both Jellup and Ned
+turned to see the nervy young reporter with the torn suit case open
+on the ground at his feet. A snap shot camera was in his hand. His
+face was white, but there was a trace of his usual smile on it. Ned
+wanted to laugh too, but the situation was too serious.
+</p>
+
+<p>
+"I've got you both," said Bob, a little nervously, "and if it's a
+good one I've got a dandy&mdash;'shooting up the town or the bad man
+covered'&mdash;"
+</p>
+
+<p>
+Had it not been for Ned's lightning-like action these might have
+been Bob's last words. Jellup's pistol had flashed once more, but
+as it dew into position Ned's own weapon rose with it under Jellup's
+right hand and the marshal's shot passed over Bob's head. Before
+Jellup and Ned could recover themselves Bob's camera was on the
+ground and the reporter had his own revolver, which he had grabbed
+quickly from the suit case.
+</p>
+
+<p>
+In the center of this group now stood, unarmed, Alan Hope and old
+Buck. Almost at the same time a dozen men, attracted by the melee,
+had also intervened and had taken charge of the three excited
+combatants.
+</p>
+
+<p>
+Pushing the crowd right and left appeared the stalwart form of Mayor
+Curt Bradley, weaponless, but with the stem face of one who gives
+orders that cannot be ignored.
+</p>
+
+<p>
+"Put 'em up, every one of you," he exclaimed; "do ye hear? Put 'em
+up."
+</p>
+
+<p>
+"Ye'r both under arrest," shouted Jellup to Ned and Bob.
+</p>
+
+<p>
+There was a quick explanation and then Mayor Bradley, still very
+stem of face, ordered everybody across the street to his office
+above the drug store. Men seemed to spring out of the ground, and
+the room was instantly packed to suffocation. Marshal Jellup made a
+formal charge against the two boys of "resisting and interfering
+with an officer" and then each told his story. The decision was
+immediate. Mayor Bradley ordered that both boys be released and the
+court be instantly cleared.
+</p>
+
+<p>
+Jellup made his way noisily toward the door, his face white with
+rage. Apparently a number present were his friends and cronies, for
+the looks of sympathy that he got turned into open murmurs of
+dissent.
+</p>
+
+<p>
+Mayor Bradley was on his feet at once.
+</p>
+
+<p>
+"What's the matter?" he began incisively. "Is there some one here
+who wants to appeal from my decision?"
+</p>
+
+<p>
+The hubbub subsided but there wag no response.
+</p>
+
+<p>
+"The time to make any complaint about my decision is right now and
+to me," went on the tall Bradley, looking over those in the room.
+</p>
+
+<p>
+But no one apparently cared to take up Jellup's cause. When the
+spectators had gone the Mayor, who had sternly watched the slow exit
+of the last loiterer, turned to the boys.
+</p>
+
+<p>
+"I thank you, Mr. Bradley," exclaimed Ned earnestly.
+</p>
+
+<p>
+"And I want to thank both of you," quickly added Bob Russell, taking
+the hand of each. "I'm the cause of this and I'm sorry. I guess
+you saved my life twice," he added, wringing Ned's hand. "If it
+hadn't been for you the Comet certainly would never have heard from
+me again. I guess that, puts all my obligation up to you."
+</p>
+
+<p>
+"No," said Ned, "I can't let you say that. You have your own duty
+just as I have mine. We'll go over to the car and wait for the two
+o'clock Limited. Then you are at liberty to go and write your story
+and do its you like."
+</p>
+
+<p>
+"He don't have to leave," interrupted the Mayor; "this is a free
+town and it's going to be an orderly one."
+</p>
+
+<p>
+"And I'm not going to," broke in Bob. "You've got yourself in a
+muss over me and some of these soreheads may try to make you more
+trouble. If you'll let me, I'll stay to the end and if it comes to
+a mix-up I'm going to be right there with you."
+</p>
+
+<p>
+Mayor Bradley smiled and old Buck slapped the reporter on the back.
+</p>
+
+<p>
+"But how about the story you say you are going to write about us,"
+asked Alan.
+</p>
+
+<p>
+"There wouldn't have been any story if it hadn't been for Mr.
+Napier," replied Bob. "And there isn't going to be one until he
+tells me to write it. It's up to him."
+</p>
+
+<p>
+Ned was looking out of the window at the curious loungers standing
+in the street. He was thinking of the work yet to be done and of
+all the difficulties that the discomfited marshal might put in his
+way. It wasn't a "picnic proposition." He didn't fear for himself,
+but the thought of his expensive and delicate outfit and of how
+easily it might be irreparably injured was not reassuring.
+</p>
+
+<p>
+"Russell," he said finally, "I think we need you. If you care to
+stay with us we'll be glad to have you. It isn't because I don't
+want to be bluffed by Jellup, but because you are game. If you'll
+go with Buck and Elmer, I'll try to make it worth your while&mdash;some
+time&mdash;and you shall be the historian of this expedition&mdash;when the
+time comes to write its story."
+</p>
+
+<p>
+Am hour later the delayed overland expedition was on its way toward
+the desert. There had been a quick shopping expedition in the
+stores of Clarkeville and Bob Russell, in a new hat and boots and
+various other articles of clothing, most of them too large for him,
+sat proudly on the driver's seat of the second wagon. Around his
+waist was a new cartridge belt and holster carrying Ned's gift, a 44
+revolver&mdash;"for game or rattlesnakes," as the boys expressed it, but
+the weapon was not concealed when the little cavalcade traversed the
+main street of the town, and if Jellup was an onlooker Ned felt sure
+that the outwitted marshal would think twice before again molesting
+the expedition.
+</p>
+
+<p>
+"All set," laughed Bob, as the final farewells had been said, and he
+held up his camera, "now for the real thing."
+</p>
+
+<p>
+Ned and Alan were now alone. To tell the truth, the excitement of
+the morning had been rather trying for them, but if it left them a
+trifle nervous they soon forgot their apprehension in making the
+last of the transfer. There was now another reason for abandoning
+the car. With headquarters established in the corral they would be
+near the balloon and its equipment, and if Jellup should permit his
+ill will to develop into some overt act, they would be in a position
+more easily to protect themselves. For that reason a number of
+their "greaser" assistants were taken to the car before noon and the
+hydrogen cask was loaded on the small wagon and carefully freighted
+to the corral. Then followed the remainder of the provisions and
+the personal belongings of the boys. Early in the afternoon the
+Placida was closed and turned over to the railway agent.
+</p>

+<p><a id="chap14"></a></p>
+<h3>
+CHAPTER XIV
+</h3>
+
+<h3>
+BUILDING AN AIR SHIP
+</h3>
+
+<p>
+When Ned announced to Alan that they would at once unpack and test
+the motor&mdash;"for we might as well stop if the engine isn't right," as
+he put it&mdash;all thoughts of the troubles of the early day vanished.
+And the motor certainly was a beauty. Though some expert had
+recommended the French motor, Ned had preferred to use one made in
+America, not only because he had been able to get it quicker but
+because he believed it as good as the foreign make.
+</p>
+
+<p>
+The engine had eight air-cooled cylinders, in two sets of four,
+placed at an angle of ninety degrees to each other. The crank case
+was of aluminum and the shaft of vanadium steel, hollow, and
+specially treated to insure toughness. All the studs or bolts were
+of the same steel. Complete, with balance wheel, it weighed two
+hundred pounds. The ignition was accomplished by six dry batteries
+and a single-wire vibrating coil. It was rated at fifty horsepower.
+</p>
+
+<p>
+So exactly had the preliminary work been done at the factory that in
+two hours the boys were able to have the engine bolted to the
+section of the car where it was to be used, and before evening the
+radiator tubes and pump of the cooling system were also in place.
+Temporary connections were set up and the sparking wires attached,
+and then the reservoir was filled with gasoline. A little jar as
+the wheel was turned, then a couple of sharp explosions, and the
+engine fell to its work as if it had been running for weeks.
+</p>
+
+<p>
+Ned shut it off after a moment's critical inspection.
+</p>
+
+<p>
+"Let her flicker!" pleaded Alan. "We've waited so long for a real
+one that I like to hear her buzz."
+</p>
+
+<p>
+"We'll let her buzz when we can use the buzz," laughed Ned.
+"Gasoline is gasoline, you know."
+</p>
+
+<p>
+Night did not stop the work of the eager lads. As soon as they had
+eaten a light meal, Ned and Alan, with a couple of lanterns and a
+half dozen of candles, began to adjust the sections of the car.
+These, seven in number, when joined, were 54.12 feet in length. The
+American spruce frame and the aluminum joints were all intact. This
+work finished the day.
+</p>
+
+<p>
+Blankets on the rough floor were good enough for the explorers that
+night. The luxury of the Placida's mattresses and fresh sheets was
+missed, as was Elmer's skill as a chef when it was time for
+breakfast the next morning. The boys were not so indifferent about
+this meal as they had been about that of the evening before. They
+had no stove, but they took the time to arrange a regular camp in a
+comer of the corral. A little fire was soon burning, at which they
+made coffee and toasted some bacon. This, with hardtack and some
+preserved fruit, they thought was enough, for they were determined
+not to disturb the carefully packed provisions that were to be
+carried in the balloon.
+</p>
+
+<p>
+"Have you had enough?" asked Ned as the last piece of scorched bacon
+disappeared.
+</p>
+
+<p>
+"Enough?" answered Alan. "A regular banquet!"
+</p>
+
+<p>
+Just then there was a loud thump on the closed door of the barn.
+</p>
+
+<p>
+"The hands are arriving," explained Ned, and he hastened to open the
+door.
+</p>
+
+<p>
+A few of the workmen were there, but the knocking had been done by a
+pleasant faced woman&mdash;apparently a Mexican. A black shawl covered
+her head and one arm. It was Mrs. Bourke, Buck's wife.
+</p>
+
+<p>
+"I thought," she said smiling, "hungry."
+</p>
+
+<p>
+Without further words she threw back the shawl and revealed a small
+tin pail. The appetizing odor made Ned's mouth water. In the
+bottom of the bucket were frijoles, or boiled and fried Mexican
+black beans cooked in pepper, and on top of these were a half dozen
+smoking hot tortillas or corn cakes.
+</p>
+
+<p>
+"Mrs. Buck," exclaimed Alan, "you have saved our lives!"
+</p>
+
+<p>
+All recollection of his recent banquet seemed to have disappeared,
+and so did Mrs. Bourke's bucket of beans and cakes, in double-quick
+order. The reward was a bright silver dollar for the thoughtful
+woman and a contract that she should come three times a day and
+prepare the boys' meals. It would have been easier to have gone to
+Buck's home, only a short distance away, but the boys were now
+determined to stay in the corral, or leave it only one at a time.
+However, they soon developed a taste for Mrs. Bourke's peculiar hot
+wholesome dishes and these, with what provisions they had on hand,
+were a fair substitute for Elmer's cooking.
+</p>
+
+<p>
+The frijoles having been disposed of, Ned at once went out, and was
+fortunate in finding a load of rough lumber and a sort of
+jack-carpenter. With the help of the boys a four foot-high series of
+"horses" or frames was set up in the center of the corral. This was
+for the car to rest on while it was being assembled. It was
+elevated so that the propeller and aeroplanes and rudder could all
+be tested after being set up. The propeller, 11.48 feet in length,
+revolved in bearings four feet above the bottom of the car.
+</p>
+
+<p>
+After noonday refreshment the middle section of the car, to which
+the engine was already attached, was carefully lifted into place
+with the aid of the workmen, and then the laborers were paid off and
+dismissed&mdash;all except the watchmen. From now on there was nothing
+that the boys could not do themselves, and they wanted to be
+undisturbed and alone. The putting together of the car was a treat
+of which they had long dreamed and they were happy in their work.
+</p>
+
+<p>
+The remaining sections were easily laid on 'the "horses" and then
+came the bolts and the bracing with piano wire. When brought
+together the fifty-four foot long skeleton was in shape much like a
+cigar. The main frame was six feet high, tapering to five feet at
+each end. In depth the dimensions were the same. The engine rested
+on the floor of the middle section and was accessible in all its
+parts from that compartment. An elevation of the floor in the
+forward part of this section made it possible for one to stand high
+enough to have an outlook in all directions through openings in a
+hooded elevation that projected above the top of the section.
+</p>
+
+<p>
+This hood was of a waterproof silk, coated with powdered aluminum,
+that metal being used because of its semi-incombustibility. This
+silk also covered the sides of the central compartment, making a
+wind-, rain- and waterproof cabin. The lookout windows on all four
+sides were covered with isinglass. The bottom of the framework of
+the car forward and aft of the engine compartment had a ladder-like
+flooring of spruce, inserted more for strengthening the car than for
+service. But on top of the car, reaching from end to end, was a
+continuous runway two feet wide which could be used in hurriedly
+visiting either propeller or rudder. This runway was protected by
+guide ropes of Italian hemp running through posts extended upward
+from the sides of the car. The top of the engine compartment was
+completely floored, making a platform 6 x 6.12 feet square. This
+was surrounded by a protecting network, and Alan named it the
+"bridge."
+</p>
+
+<p>
+A light rope-ladder extended into the engine cabin from an opening
+in the roof, making the top floor space or bridge and the upper
+runways quickly accessible. The gasoline reservoir, just forward of
+the engine, was connected with the bridge by a copper supply pipe.
+The extra supply of gasoline was to be carried on the bridge in the
+open air, and lashed to the netting instead of being stored in
+permanent reservoirs as is the usual practice. This was in order
+that the empty vessels might be thrown overboard when it was
+necessary to lighten the balloon.
+</p>
+
+<p>
+The other sections of the car were each 8 feet long and decreasing
+in height from 6 feet next the cabin to 5 feet at the end of the
+car. In the two sections just forward of the cabin and in the two
+just aft provision had been made for attaching the eight liquid
+hydrogen casks&mdash;four at each end. As this liquid was reconverted
+into gas the light sheet-iron casings might likewise be cast
+overboard to lighten the balloon. As needed, the liquid hydrogen
+jars, coated with mercury, were to be taken from their casings and
+carried to the bridge where the reconverter was located.
+</p>
+
+<p>
+Aft of the engine cabin was the store room for water and provisions.
+The grooves and rods for the counterweights and equilibrium adjuster
+ran in the middle of the upper footway and the propeller shaft
+rested on the bottom of the forward section of the car.
+</p>
+
+<p>
+At ten o'clock that evening all the work on the car was finished
+except the buckling on of the aluminum silk sides and the hanging of
+the propeller, the rudder and the aeroplane sides. It was as long
+and as hard a day's work as either of the boys had ever done. They
+were dead tired, but happy, and after a sousing wash-up they got
+into their pajamas and, throwing their blankets on the floor of the
+little office, were soon fast asleep.

+<h3>
+CHAPTER XV
+</h3>
+
+<h3>
+HOW JACK JELLUP LOST AN ARM
+</h3>
+
+<p>
+In spite of his fatigue Ned did not sleep soundly. It had been
+threatening a thunder storm all evening and the increasing
+oppressiveness of the air made the young, aeronaut wakeful. The
+long whistle and jarring stop of the midnight local train finally
+fully aroused him. In the west the thunder was rumbling and great
+sheets of heat lightning promised a storm in a short time. After
+slipping out into the corral and seeing that the waterproof silk
+sides of the car were securely buttoned around the engine Ned
+returned and again tried to go to sleep.
+</p>
+
+<p>
+But his restlessness continued. In his early sleep he had had a
+vivid dream about the wagon expedition. In this he thought that
+Marshal Jack Jellup had followed Elmer, Bob and Buck and set fire to
+the wagons while his friends were asleep in camp. It was a relief
+to awaken and find that the flash of light was lightning and not, as
+he had imagined in his dream, an explosion of the gasoline carried
+in Buck's big wagon. He lay awake awhile regretting the quarrel
+with Jellup, and then he sank into a doze again.
+</p>
+
+<p>
+But his active brain would not rest. Again he fell into a dream.
+This time the picture was very real. The big balloon had been
+finished and launched. A thrill ran through him as he felt the
+monster craft poise and waver and then slowly rise above the corral.
+He could hear the cheers of those gathered about. But in the midst
+of them he heard the sudden crack of a revolver. Jack Jellup had
+put a bullet through the silken bulk of the bag. The cold
+perspiration broke out on Ned's forehead.
+</p>
+
+<p>
+The dream was so real that he thought he could hear the taunting
+voice of Jellup. In feverish excitement Ned sprang upright, to find
+a pair of strong arms clasped about him. He did not cry out. A
+wave of cold fear seemed to benumb his tongue and brain. He knew
+this was no dream.
+</p>
+
+<p>
+Forced onto his back, his face and eyes partly covered by the
+shoulders of his sudden captor, Ned's returning consciousness made
+him aware that there was a dim light in the office.
+</p>
+
+<p>
+"It's Jellup, Ned," exclaimed in a whisper a sudden voice which Ned
+instantly recognized as Alan's.
+</p>
+
+<p>
+"No more from you," exclaimed a rough voice in quick reply. "Here's
+the rope, Domingo."
+</p>
+
+<p>
+The man on top of Ned knew his business. Almost before the boy
+realized what was being done his hands and feet were caught in
+dexterous knots and he was helpless.
+</p>
+
+<p>
+"Now," continued the other voice, "let's have a few minutes' talk."
+</p>
+
+<p>
+Ned's assailant had arisen, and for the first time the boy could
+look about. In the center of the room, with a sputtering candle in
+his hand, stood the revengeful Jellup. His companion Ned at once
+remembered as one of the noisy court room spectators of the day
+before. Between the two, clad in his pajamas and similarly bound,
+was poor Alan.
+</p>
+
+<p>
+"Ye can stand or set, jist as ye like," began Jellup. "Me and me
+deputy hev made this little visit to ye fur a purpose. The citizens
+of this town is tired of yer carryin's on and they've just delegated
+me to ascertain what it all means. We got a purty good idee."
+</p>
+
+<p>
+"Well, what is your idea?" interrupted Ned, slowly regaining his
+composure and his natural defiance.
+</p>
+
+<p>
+"My idee is that ye don't need no flyin' machine anywhar except to
+git away quick and what we want to know is what air ye goin' to take
+with you when ye fly away?"
+</p>
+
+<p>
+"Nothing that doesn't belong to us," answered Ned, "if that is what
+you mean."
+</p>
+
+<p>
+"Ye ain't, eh? I suppose ye don't know that thar's enough cow money
+in our bank to be worth stealin'?"
+</p>
+
+<p>
+Both Ned and Alan looked at each other astounded.
+</p>
+
+<p>
+"You don't think we look like safe robbers, do you?" began Alan.
+</p>
+
+<p>
+"Ye look just slick enough fur that and more," retorted the marshal
+who had placed the candle on the table and roughly pulled Ned to his
+feet. "But I didn't come here to argy. Ye began by vilatin' the
+law and ye didn't come the way down here for no fun. Ef that ain't
+yer game, and we don't put it above ye, what's yer lay?"
+</p>
+
+<p>
+"There's only one answer," said Ned. "None of your business."
+</p>
+
+<p>
+The marshal shoved Ned nearer the table.
+</p>
+
+<p>
+"Mebbe ye want to apologize fur that little bluff of yers
+yesterday&mdash;"
+</p>
+
+<p>
+"No," said Ned, "but I'll accept yours."
+</p>
+
+<p>
+Jellup's right hand was on his revolver.
+</p>
+
+<p>
+"I ain't hyar to make no threats," he exclaimed, "and ye don't need
+to be afeered that I'm going to shoot ye. But I've got just one
+other little proposition. Ef ye don't cotton to that, why, thar
+ain't agoin' to be no Fourth o' July balloon ascension around hyar."
+</p>
+
+<p>
+Ned straightened up.
+</p>
+
+<p>
+"Your proposition can't be a fair one or you wouldn't come like a
+thief at this time of night&mdash;"
+</p>
+
+<p>
+Jellup's pistol flashed in the air but fell back again as the
+marshal's left hand shot upward and struck Ned full in the face.
+Even as the tears sprang into the bound boys eyes and pain and anger
+flushed his pallid face, the cowardly Jellup fell backward and
+stumbled to the floor. Alan, standing just behind the man, had shot
+his knees forward, striking Jellup's legs in the hollow of his
+knees, and, thrown off his balance, the westerner lay sprawling on
+the floor. Before the marshal's confederate could interfere, Alan,
+tightly as he was bound, had flung himself on top of Jellup and with
+all the power he could throw into the act had butted his head into
+the marshal's face.
+</p>
+
+<p>
+Am oath and a cry of pain indicated how true the stroke had been.
+Both Ned and the companion of Jellup sprang forward at the same time
+and the four fell in a silent distorted heap. But the encounter was
+unequal. In another moment both boys were lying side by side on the
+floor and their captors stood over them. Even in the half light of
+the little room both boys could see the blood-smeared cheek of the
+marshal.
+</p>
+
+<p>
+Jellup's hand was on Domingo's arm holding him back from further
+attack on the helpless boys and the marshal was restraining his
+anger as a snake withholds its venom until it strikes.
+</p>
+
+<p>
+"Purty good," sneered the marshal, "and the funny thing is ye hain't
+got a bullet through ye fur it. But my business ain't with dead
+ones. Onct more, air ye goin' to say what ye'r a plannin' to do?"
+</p>
+
+<p>
+"Since it doesn't concern you in the least," said Ned, slowly, "no."
+</p>
+
+<p>
+Jellup was silent a moment.
+</p>
+
+<p>
+"Fur kids ye seem to have plenty o' money. Ye'r purty free
+spenders. I'll give ye one more chance. Ef ye've got a thousand
+dollars handy fur a kind of a bond as it were I guess that'll sort
+o' protect us."
+</p>
+
+<p>
+"You mean for bribery?" exclaimed Alan.
+</p>
+
+<p>
+"No, just instead of stealing," angrily added Ned. "We haven't a
+thousand dollars and if we had you couldn't get a cent of it. And
+to save you some trouble I'll say that what we have is in your
+bank."
+</p>
+
+<p>
+Another half-uttered oath sounded on Jellup's lips.
+</p>
+
+<p>
+"In thet case," retorted the marshal, "we'll jest show you that we
+mean business. That's a lie about the bank. Produce or take the
+consequences."
+</p>
+
+<p>
+"Help yourself," replied Ned, "if you think we are lying."
+</p>
+
+<p>
+"I ain't no pickpocket," retorted Jellup, "this is official. I tell
+ye it's a bond and this is yer last chanct to make good."
+</p>
+
+<p>
+The boys remained silent.
+</p>
+
+<p>
+But Jellup's companion was already busy. Leaving the marshal to
+stand guard over the boys he made a quick search of their clothing.
+But Ned was not so used to money as to be careless in the handling
+of it and the six hundred dollars that he had in gold was in a belt
+carefully concealed in the top of the liquid hydrogen crate, which,
+for safety, had been stored in a corner of the room.
+</p>
+
+<p>
+When the silent Domingo threw down the working garments of the boys
+he took up the candle and began a tour of the room. The big black
+liquid hydrogen crate attracted his attention and he approached it.
+The red "Explosive&mdash;no fire" letters of warning apparently meant
+nothing to him, but Jellup halted him with a sharp warning, followed
+by a few words in Mexican. Domingo handed the candle to Jellup and
+the latter stepped toward the box.
+</p>
+
+<p>
+"That means what it says," exclaimed Ned quickly and sharply.
+</p>
+
+<p>
+The crate stood as it had been carried from Washington with the top
+on and the connecting hose extended upward through a hole made in
+the low roof in order that the slowly accumulating reconverted gas
+might escape in safety.
+</p>
+
+<p>
+"Mebbe," said Jellup, "mebbe yes and mebbe no. I guess they ain't
+nothin' agoin' to explode that ain't set afire."
+</p>
+
+<p>
+Ned noticed with satisfaction that the lid was properly locked.
+Jellup noticed it too. Without a word, he turned and easily found
+Ned's keys. Again he approached the crate, looking over the keys.
+</p>
+
+<p>
+"Jellup," exclaimed Ned in alarm, "there's gas in that box, and if
+you go near it with a light you'll blow us all up."
+</p>
+
+<p>
+"Gas, eh?" answered the eager Jellup. "Don't run no sich bluffs on
+me."
+</p>
+
+<p>
+"I warn you," cried Ned as the man approached the box, "it's taking
+your life in your hands."
+</p>
+
+<p>
+Something in the tone of Ned's voice must have alarmed Jellup, for
+he paused. Then he retreated a few steps and handed the almost
+burned out candle to the vigilant Domingo.
+</p>
+
+<p>
+"I allow I kin jest hev a look without no light to oblige you. I've
+been purty curious about this precious package ever since I see it.
+And ye'r a sight too anxious consarnin' my safety."
+</p>
+
+<p>
+What might really happen Ned did not exactly know. The gas
+generated from the liquid hydrogen was highly inflammable and
+explosive when confined. But the evaporation was exceedingly slow
+and the exhaust hose should easily carry the forming gas in safety
+to the air. But even a small accumulation might be in the partly
+depleted bulbs or the top of the crate and a fire would certainly
+ensue even if there was no violent explosion. And besides, just
+beneath the lid was their money&mdash;the cash Ned had secured for their
+further expenses and the return home.
+</p>
+
+<p>
+"We are anxious for all of us," explained Alan.
+</p>
+
+<p>
+"And mebbe anxious fur something else," sneered the marshal. "I
+reckon a peek in the dark ain't agoin' to hurt no one&mdash;an' it may
+help some."
+</p>
+
+<p>
+"Drop on your face, Alan," whispered Ned, "and lie flat."
+</p>
+
+<p>
+It was the only precaution they could take. Both felt that all
+their plans might end in a moment. But Ned could not resist
+watching&mdash;even though his face was close to the floor. He saw
+Jellup examine each key, guess the right one at once and then insert
+it in the lock. Yet, despite his assumed bravado, it was apparent
+that the man had considerable apprehension. For, before he turned
+the lock, he motioned to Domingo to retire further with the candle.
+</p>
+
+<p>
+Finally, as if summoning his courage, the avaricious marshal snapped
+the key, threw back the catches on each end of the crate and then
+slowly and gingerly and at arm's length began to lift the lid. With
+the top an inch ajar he paused, waited a moment or two, and then
+began sniffing as if searching for an odor.
+</p>
+
+<p>
+Ned saw him.
+</p>
+
+<p>
+"It doesn't smell," he explained quickly, "but it's there. Look
+out!"
+</p>
+
+<p>
+"Don't smell!" retorted Jellup. "Gas as don't smell? Well, that's
+agoin' some, I guess."
+</p>
+
+<p>
+Nevertheless, he had dropped the lid.
+</p>
+
+<p>
+But as quickly recovering himself he reached forward again and with
+a quick motion threw the top up and sprang back.
+</p>
+
+<p>
+To Ned's relief nothing happened. Either the light was too far away
+or the gas had all been removed by the hose. But this relief was
+quickly succeeded by another alarm. There had been no explosion,
+but their financial means were now at the mercy of two thieves, and
+he and his churn, bound and helpless, were powerless to protect
+either themselves or their funds. There was nothing to be done but
+to grin and bear it. For Ned's new leather money belt, containing
+six hundred dollars in gold was stretched out conspicuously and at
+full length on top of one of the two rows of glass bulbs in the
+case.
+</p>
+
+<p>
+"Lyin', as I thought," exclaimed Jellup. "Gimme' the light,
+Domingo." And the chuckle that followed almost instantly was
+indication enough that he had discovered the boys' small fortune.
+</p>
+
+<p>
+"Dangerous, eh!" he laughed. "Now, we'll see if the city gits its
+bond."
+</p>
+
+<p>
+Then he paused as if a thought had entered his head.
+</p>
+
+<p>
+"But, jest to keep the record clean, I reckon ye'd better give it to
+me yerself, young 'un. Jack Jellup ain't no burglar. Loosen him
+up, Domingo. And fur fear ye might need persuadin' jest take a peek
+at this," and he drew his revolver.
+</p>
+
+<p>
+When Ned had been liberated, Jellup pointed to the money belt.
+</p>
+
+<p>
+"Jest be good enough to hand me whatever's in that," he exclaimed,
+"without no hesitation. Then we'll have a little talk about what
+else is agoin' to happen."
+</p>
+
+<p>
+It was hard to surrender so easily but the risk of attacking two
+armed men single-handed was great. Ned walked slowly toward the
+crate.
+</p>
+
+<p>
+"Get busy," ordered Jellup; "we've got other business yit to talk
+of."
+</p>
+
+<p>
+Ned had a sudden impulse. The thing flashed on him and taking hold
+of the belt in the middle he lifted it until the two ends were just
+over an open-mouthed bulb of hydrogen, and then as if by accident
+dropped the belt into the jar. The clear, watery liquid splashed
+and the belt disappeared.
+</p>
+
+<p>
+"Water," shouted the eager Jellup, "Jist plain water." And as Ned
+sprang back the gold-fevered marshal sprang forward and plunged his
+hand into the liquid.
+</p>
+
+<p>
+He did not immediately know that his hand was in the depth of a
+liquid whose temperature was 423 degrees below zero. But the thin
+film of gas that instantly formed and protected his naked flesh
+dissipated in a moment and then one benumbing, paralyzing shock
+swept over Jack Jellup's body.
+</p>
+
+<p>
+With a cry wrung from him by pain such as few mortals have ever
+experienced and survived, the stricken man fell unconscious to the
+floor&mdash;his arm frozen as solid as crystallized steel.
+</p>

+<h3>
+CHAPTER XVI
+</h3>
+
+<h3>
+READY TO "LET GO ALL"
+</h3>
+
+<p>
+In the confusion that followed the sudden extinction of the candle,
+while Ned was freeing Alan and Jack Jellup was uttering heartrending
+groans, the marshal's confederate lost his nerve and made his
+escape. When a lantern had been procured, immediate attention was
+given to the stricken man.
+</p>
+
+<p>
+Ned hastened to secure a bucket of water. Wrapping the corner of a
+blanket about the handle of a tin dipper he ladled out a spoonful of
+the liquid hydrogen and, although the numbing chill ran through his
+fingers and up his arm, he managed to pour the hydrogen into the
+contents of the bucket.
+</p>
+
+<p>
+The pail of lukewarm water became almost instantly a cake of solid
+ice. As Ned dropped the tin dipper to the hard adobe floor it flew
+into a hundred pieces. The inconceivable cold had crystallized the
+metal until the slightest shock was sufficient to break it into
+pieces.
+</p>
+
+<p>
+At the sound of the crashing tin Ned instantly thought of the belt
+of gold yet in the hydrogen jar. But a human being was in pain, and
+he gave his first attention to the suffering marshal. He had made
+the ice to use in drawing the frost out of Jellup's frozen arm. In
+a few moments he had mashed a portion of the ice into small bits,
+and using a blanket to make a pack, he soon had Jellup's rigid arm
+encased in the fine ice. This he applied for the same reason that
+snow and ice water are applied to frozen ears and noses. But his
+treatment was of no avail.
+</p>
+
+<p>
+The rain was now falling steadily and it was dark, but Ned found
+that it was nearly day&mdash;a little after four o'clock. Jellup's
+suffering was so extreme that the boys had given him a hypodermic
+insertion of morphine, using their "snake-bite" outfit, and in a few
+minutes the man's ravings ceased and he quieted into a deep sleep.
+</p>
+
+<p>
+While awaiting this, attention was given the gold. Feeling free to
+approach the now open jars with a light it was seen that a portion
+of, the belt protruded above the liquid. A cord with a sailor slip
+knot was lowered over the extended bit of leather, drawn taut with a
+jerk and the belt was slowly lifted out. A folded blanket had been
+placed on the floor to receive it. As Ned expected, the leather
+crumbled and broke like glass as the belt fell on the soft blanket.
+</p>
+
+<p>
+"If you want change for a twenty-dollar gold piece just tap one of
+those with a stick." said Ned, laughing and pointing to the gold
+pieces scattered among the broken fragments of the belt.
+</p>
+
+<p>
+"Not I," exclaimed Alan, "not after what happened to the tin
+dipper."
+</p>
+
+<p>
+Leaving Alan to watch over the unconscious Jellup and the frozen
+gold, Ned dressed himself, and in spite of the rain hastened out in
+the just perceptible dawn to carry out a plan he and Alan had agreed
+upon. An hour later, with the assistance of Mayor Bradley, the
+marshal, now somewhat easier, was placed in a bed in his own home.
+Unless the silent Mexican told it no soul in all Clarkeville other
+than Mayor Bradley and the air ship boys knew why Jellup was absent
+from his haunts and his post of duty that day. Nor did many of them
+ever know, when Jellup reappeared on the streets after weeks of
+suffering, how he had been injured. They only knew that his right
+arm was gone and that he was no longer marshal.
+</p>
+
+<p>
+The rain ceased with the coming of the day.
+</p>
+
+<p>
+"If we don't get away pretty soon," suggested Alan, as Ned was
+getting into dry clothing preparatory to tackling another of Mrs.
+Buck's meals, "this thing will be getting on my nerves."
+</p>
+
+<p>
+"Well," answered Ned philosophically, "there is mighty little worth
+having in this world that isn't hard to get."
+</p>
+
+<p>
+If all went well that day the boys hoped to be ready to make their
+departure that night or the next morning. Therefore they went to
+work with a vim. Both felt more comfortable when, after finding
+that the gold coins had returned to their normal condition, they had
+again concealed them. The propeller, rudder and aeroplane guides
+were now put in place and tested.
+</p>
+
+<p>
+As the engine, with a speed of 1,400 revolutions but geared down to
+800, began to turn the shaft and the twelve-foot propeller began to
+revolve, Ned swung his hat in the air. Without a break the speed
+increased to 500, 600, and then 700 revolutions a minute.
+</p>
+
+<p>
+"Shut her off," exclaimed Alan joyously, as the white arms flew
+round and round and the air shot backwards on both sides of the long
+car. At 750 revolutions the car was rocking and lurching as if it
+would soar birdlike into the air. At 800 the powerful pulling
+propeller began to overcome the rigidity of the framework on which
+the car rested and as Alan caught and held the car, fearful that it
+was about to fly away under the propeller power alone, Ned shut off
+the engine.
+</p>
+
+<p>
+The next instant the two boys, with clasped hands, were doing an
+Indian war dance in their glee.
+</p>
+
+<p>
+It was not long until the rudder wires and the aeroplane shafts had
+been attached to their proper guide wheels in the lookout or pilot
+portion of the engine cabin. Then came the preparation of the
+balloon bag itself. Here again Ned showed what he had accomplished
+in the six weeks he had spent in the East.
+</p>
+
+<p>
+Clearing a space near the generating tanks, they placed the one
+hundred sand bags, weighing forty pounds each, in parallel rows.
+These sacks, with convenient loops on each for attaching the rigging
+of the bag as it was being filled, had already been prepared by the
+"greaser" laborers, but the placing of the two tons of dead weight
+was not a joke, and the boys regretted that they had not kept a few
+men around. But by noon this was done, and then the great
+waterproof fiber trunk containing the silk bag was rolled out
+between the retaining bags. The boys could not carry it, as the
+balloon itself weighed seven hundred and twenty pounds, but they
+improvised rollers and with many a laughing "yo he ho" finally
+accomplished the task.
+</p>
+
+<p>
+The bag had been made by one of the leading aeronautical engineers
+of America, whose factory, strangely enough, was in one of the small
+inland towns of New York State. In a spirit of humor the
+manufactory had been termed the "Balloon Farm," and so famous was it
+that Ned had even planned to spend a part of his summer vacation
+visiting it. When Major Honeywell gave him the opportunity, Ned was
+at once determined to utilize every advanced idea of the skilled
+owner, whatever the cost.
+</p>
+
+<p>
+The result was a machine-varnished and, as nearly as such a thing
+was possible, hydrogen gas-proof bag. In the construction of this
+the experienced manufacturer and engineer, who was no other than
+Professor Carl E. Meyers, the hero of hundreds of ascents, had used
+a new machine which applied simultaneously to both sides of the bag
+fabric several thin films of elastic varnish. The bag itself
+consisted of two layers of Japan silk between which was a layer of
+rubber, all being sewed together and then vulcanized.
+</p>
+
+<p>
+But the balloon trunk was not opened at once. The pipe to convey
+the gas from the cooler and purifying tank had been brought in
+four-foot lengths of light wood, cemented and shellacked. Eight
+lengths of these were laid to the center of the cleared place and
+then the joints were wound with binding cement tape. When these
+things had been satisfactorily adjusted it was mid-afternoon.
+Everything now seemed ready for the filling up of the generating
+tanks, the inflation, the flight, and "good-bye."
+</p>
+
+<p>
+Therefore, a final consultation was held. Wind tests conducted each
+day had shown the prevailing breezes favorable, or at least not
+against the aeronauts. The inflation would require approximately
+ten hours. If begun at once this would make the departure possible
+about midnight. This was not undesirable as the absence of the hot
+southwestern sun would make the gas easier to control. But another
+thing had to be taken into consideration. Only four days had
+elapsed since Elmer and Bob and Buck had started. Were they yet at
+the rendezvous?
+</p>
+
+<p>
+"I don't see what difference that makes," said Alan. "We expect to
+sail directly north and east of the foothills. If they have not
+reached their camp they must be nearly there and on the way. We've
+got to locate them with our glasses anyway. Let's start and pick
+them up where we find them."
+</p>
+
+<p>
+"True enough," answered Ned. "The way the engine is working, in
+this light favoring wind, we ought to make eighteen miles an hour
+anyway. If we leave at midnight, by five o'clock in the morning we
+can be ninety miles north. The only trouble is in the handling of
+the bag. It's going to take at least twenty men to move the
+inflated bag from the retaining weights to the car and we can't make
+the rigging fast in the dark. We'd better begin work at four
+o'clock to-morrow morning, as soon as it begins to be light, and get
+away about two in the afternoon. I think we'll see our friends
+about seven or just at dark, if we do."

+<h3>
+CHAPTER XVII
+</h3>
+
+<h3>
+AN INTERRUPTED FLIGHT
+</h3>
+
+<p>
+And so it was arranged. The young aeronauts thus had all afternoon
+to store provisions, water, gasoline and the instruments. The
+altitude barometer, the recording thermometer, the statoscope and
+recording hygrometer, together with the telescopic camera were each
+given a place on the bridge and lashed to the netting. The
+twenty-five-foot rope-ladder, strong but light, that was to hang
+below the car, and the anchor and drag rope, were attached, the name
+pennant of white with the word "Cibola" resplendent in blue, "turquoise
+blue," explained Ned&mdash;was unfurled on its little staff just abaft the
+big propeller, and a new silk American flag was laid out it the stern
+of the car to be run up on its halyards as soon as the bag was attached.
+</p>
+
+<p>
+Then came the careful transfer of the liquid hydrogen. One at a
+time the cast iron eases were carried from the building, hoisted
+aboard the car and lashed in place. Before supper Ned had time to
+go to the depot and send a telegram to Major Honeywell, who was yet
+in Chicago. It read:
+</p>
+
+<p>
+"Ready for inflation. All O. K. Sail at 2 P. M. to-morrow, August
+11."
+</p>
+
+<p>
+He then visited "Saloon Row" and arranged for twenty men to report
+at four o'clock the next morning. No chances were to be taken that
+night. Dividing the hours up to four A. M. into two watches, the
+two boys had supper and Ned was soon fast asleep on the floor of the
+car "trying it out."
+</p>
+
+<p>
+At the first blush of dawn the corral gates were thrown open and in
+a short time all the men engaged reported. Some of them were put to
+work dumping the heavy iron filings into the big oak gas generators
+and Ned and Alan began the delicate work of laying out the bag,
+bottom side up the thin silken folds of the golden shell were slowly
+lifted and laid on the ground. When the bottom filling valve had
+been attached to the wooden gas conduits the mammoth sections of the
+long gas receptacle were stretched out on top and then carefully
+smoothed until an even inflation was assured.
+</p>
+
+<p>
+This done, the rigging trunk was opened and the seine-like mass of
+delicate hemp cords laid over the bag. No "greasers" were permitted
+to assist in this. Ned and Alan, in bare feet, laboriously but
+carefully drew the silk folds of the bag into the net. When this
+was completed the suspension cords reached out in all directions
+like skeleton fingers. In a quarter of an hour these had been
+attached to the retaining bags with slip knots and then the boys
+were surprised to find that it was already after six o'clock. At
+their best they could not now hope to reach the relief camp before
+nine o'clock and after dark.
+</p>
+
+<p>
+Mrs. Buck came with a huge pot of coffee for all, and then followed
+the last step. One by one, borne on the shoulders of the curious
+workmen, the dangerous carboys of sulphuric acid were emptied into
+the generating tanks. The boys guided each step of the men,
+explaining the danger, and the work was finally completed without
+hitch or accident.
+</p>
+
+<p>
+At the first bubble of gas the boys felt like doing another war
+dance. But they were "business men" now and had to put on dignity
+in the face of their employees. In two hours the reaction of the
+bubbling acid had sent enough hydrogen through the purifier to raise
+the bag shoulder-high and everything was going splendidly. The boys
+had removed their working clothes and were now in the light but warm
+canvas suits and caps they meant to wear in their flight.
+</p>
+
+<p>
+Ned stole away a few minutes and at the bank secured bills to pay
+off the men. On his way back he stopped to invite Mayor Bradley to
+lunch with them on the Cibola and to be present at the "let go." By
+noon the men had been paid and the articles of baggage and tools
+that were to be left behind had been packed, tagged with shipping
+directions and turned over to Buck's wife.
+</p>
+
+<p>
+The cigar-like bag, 98.4 feet long and 17.4 feet in diameter, which
+was to hold over 65,000 feet of gas, was now so far inflated that it
+was nearly off the ground. Then Mayor Bradley came. With pride the
+boys bade him climb into the cabin of the Cibola.
+</p>
+
+<p>
+"You won't find anything hot in a balloon, Mr. Mayor," laughed Ned,
+"except the reception. Make yourself at home."
+</p>
+
+<p>
+On the bridge of the craft the two boys and their guest had
+luncheon. Cold potted chicken and baked beans served on wooden
+plates with hardtack and water, and sweet chocolate for dessert, was
+the simple meal, but it tasted like a feast.
+</p>
+
+<p>
+"Have you christened the craft yet?" finally asked the Mayor who had
+absorbed some of the enthusiasm of the young aeronauts.
+</p>
+
+<p>
+"That's for you to do," politely answered Ned.
+</p>
+
+<p>
+The luncheon was hurried to a finish, for the boys could see that
+the bag needed final attention. It had risen higher and higher and
+was now swaying and tugging at the suspension ropes. Both boys
+alighted and at once began straightening the extension ropes. Here
+and there where the cordage net was out of place they pulled down
+the bag and adjusted the rigging. Finally a little after three
+o'clock, the great case had filled out until its smooth glistening
+sides resembled the skin of a fat sausage.
+</p>
+
+<p>
+"All ready!" ordered Ned as he shut of the valve of the cooling and
+purifying box. "Now, every man bear a hand."
+</p>
+
+<p>
+One at a time the extension cords were untied from the retaining
+bags, and each of the workmen was given four of the light but strong
+lines. The Mayor himself passed among the men with stern
+injunctions to hold fast. As the last cord was loosed the great
+tugging bag was held wholly by the scared men. Then, with slow and
+measured steps, the double line of assistants advanced to the car
+and along each side of it.
+</p>
+
+<p>
+"All steady," commanded Ned when each man had been placed; "now hang
+onto her."
+</p>
+
+<p>
+Then he and Alan, springing into the car, began the work of making
+it fast to the bag. There was a place marked for each of the
+extension ropes, and the air ship builders, beginning at each end of
+the car, carefully adjusted and tied the end of each rope to the
+frame of the ship. As the cords were taken from the attendants the
+men took hold of the lower framework of the car, and to make doubly
+sure each man was cautioned to throw his entire weight into the
+work.
+</p>
+
+<p>
+At last the final rope was made fast, and three thousand pounds of
+human flesh and muscle were holding the tugging balloon. Ned,
+covered with perspiration, and nervous but happy, was hastily
+connecting the compensating balloon tube with the hand blower on the
+bridge, and Alan had run astern to tie the new national colors to
+the halyards swinging from the end of the bag.
+</p>
+
+<p>
+"Hold on," cried Ned seeing that Alan was ready to run up the stars
+and stripes. "Just a moment. Are you all ready, Mr. Mayor?"
+</p>
+
+<p>
+"All ready," came the answer from the town official, as he stood on
+a box, his hat off and a revolver in his hand.
+</p>
+
+<p>
+"With a western salute I christen this balloon the 'Cibola,'" he
+exclaimed, and a shot punctuated his speech. "Good luck and
+goodbye!"
+</p>
+
+<p>
+As the shot sounded Alan's flag ran fluttering upwards. Ned's eyes
+took one final look fore and aft and then he leaned over the car for
+the last words for which all were waiting.
+</p>
+
+<p>
+They were on his lips and the eyes of twenty straining men were
+fixed on him to hear the command, "Let go." One nervous attendant,
+apparently thinking the order had been given, threw up his arms with
+a shout.
+</p>
+
+<p>
+At that instant there was a second sharp pistol shot, and a quick
+cry from the street outside the corral.
+</p>
+
+<p>
+"Hold on there, all of you!" shouted Ned. His dream had rushed back
+to him with a sickening chill. Had some one shot at the towering
+bag? "Hold on!" he yelled.
+</p>
+
+<p>
+At that moment there was another shout and Bob Russell, his face red
+with the sun and his shirt wet with perspiration, walked into the
+corral. In his right hand was gripped a revolver and in his left a
+repeating rifle. In front of him, and prodded on by Bob's pistol,
+was the Mexican, Domingo, Jack Jellup's tool and fellow thief.

+<h3>
+CHAPTER XVIII
+</h3>
+
+<h3>
+FREE AND AFLOAT AT LAST
+</h3>
+
+<p>
+This is what had happened.
+</p>
+
+<p>
+At the time of the rain storm, two days before, Buck and his
+cavalcade were in camp on the bank of the dry Chusco, sixty miles
+north of Clarkeville. The experienced scout knew that a water
+supply was now assured, and he at once followed prearranged orders
+by instructing Bob to return with the smaller wagon. This was a sad
+blow to the young reporter, but it was a part of his contract and he
+knew that it was his duty to obey. And with necessity before him,
+he acted promptly. Emptying the heavy casks, Bob started on the
+back trail at five the following morning, and by night had made
+thirty miles with the light wagon. All day he wondered if it might
+not be possible to reach Clarkeville again before the Cibola sailed.
+</p>
+
+<p>
+The next morning, spurred on by the hope that he might do this, he
+started at daybreak. By the middle of the morning he was on the old
+wagon trail and making better time. Some time after two o'clock he
+came up over the rise of the last foothills and saw, eight miles
+away, the glistening shape which he at once knew was the inflated
+balloon. He hesitated a moment and then, unhitching the horses,
+mounted one bareback and began a dash for the town. The animals
+were tired and worn, and progress was slow, but it beat walking, and
+Bob urged them on.
+</p>
+
+<p>
+As the young reporter came nearer and the balloon grew more distinct
+he knew that it would be a close call. From time to time as the
+winded horses dropped into a walk Bob wondered why he was making
+such a race. "I can't go with them," he argued. But, like the
+trained reporter, he decided that no effort was wasted that gave him
+new information. And it was something out of the ordinary to see
+the most complete balloon ever made start on a mysterious flight
+into the wilderness.
+</p>
+
+<p>
+So he spurred up the horses anew. The hot sun reflected from the
+yellow sands burnt his face and his muscles were sore, but he stuck
+to it. When half a mile from the town he could see the boys on the
+bridge of the Cibola. When a quarter of a mile away he decided that
+he could beat the horses by going afoot, and, throwing himself to
+the ground, he ran onward, knowing that the tired animals would
+follow. Out of breath he reached the edge of the town and stumbled
+on toward the corral.
+</p>
+
+<p>
+With head down he plunged forward. Almost at his goal he threw his
+head up for breath just in time to notice a kneeling man with a
+rifle at his shoulder.
+</p>
+
+<p>
+"Hey!" yelled Bob with what breath he had.
+</p>
+
+<p>
+Then he saw that the man was aiming directly at the balloon swaying
+above the nearby corral fence. He also recognized the man instantly
+as one of the sullen court spectators, and Jellup's crony. The
+rifleman dropped the muzzle of his gun and turned.
+</p>
+
+<p>
+"I guess I am something of a gun man," explained Bob later to the
+boys, "for I had that new revolver of mine on the 'greaser' before I
+knew what I was doing myself. I didn't even then realize what he
+was about to do. But I had the drop on him and when I figured out
+that he meant to put a hole in the balloon, why, I just had him
+right. And here he is."
+</p>
+
+<p>
+Alan looked at Ned. Both boys were puzzled. A few moment's talk
+with Russell explained the whole situation. The balloon was ready
+and the relief expedition was undoubtedly now in camp awaiting them.
+It needed only the words and they would be off with the inquisitive
+reporter left safely behind. And yet the word did not come. Ned
+and Alan stood looking at Bob, and the reporter gazed in turn at the
+beautiful straining car. Bob's face was a study. He had now made
+some return to Ned for possibly saving his own life, but none of the
+boys was thinking of that. In Bob's fine young face was the longing
+of a child. In Ned's and Alan's faces were the traces of boyish
+sympathy.
+</p>
+
+<p>
+The young aeronauts were very close to each other and all were
+silent. Then Alan turned slowly to Ned and with a little quaver in
+his voice whispered, "Shall we?"
+</p>
+
+<p>
+Ned made no answer. A smile lit up his face and he sprang down the
+little ladder into the engine cabin followed by his chum. Almost
+instantly the trap door in the floor of the car dropped down. A
+moment later three fifty-pound sacks of ballast tumbled through the
+door to the ground beneath. The bag tugged and strained as Ned
+reappeared above.
+</p>
+
+<p>
+"Hurry up, Bob, if you're going with us," he said quietly, leaning
+over the net of the bridge, "and close the door as you come up."
+</p>
+
+<p>
+Bob hesitated, as if he had not heard aright, but then he
+understood, and with tears in his eyes be sprang forward. There was
+a jar and Ned knew the new passenger was aboard.
+</p>
+
+<p>
+"All ready?" he called sharply from the bridge.
+</p>
+
+<p>
+"Aye, aye, captain," came in a choking but jubilant voice from the
+inside of the cabin.
+</p>
+
+<p>
+"Stand by, everybody," sharply ordered Ned. And then, as Bob's
+shoulders appeared through the hatchway, the commander of the air
+ship gave a final look about.
+</p>
+
+<p>
+"Let go all," he cried sharply. "Everybody!"
+</p>
+
+<p>
+For a moment only one clinging workman careened the buoyant craft
+and then, straight up, the Cibola bounded like a rubber ball.
+</p>
+
+<p>
+"Good-bye, all," came from Ned, cap in hand, as he leaned from the
+bridge.
+</p>
+
+<p>
+There were cheers from below and the Cibola was at last free and
+afloat.
+</p>
+
+<p>
+"Sit down here and keep quiet," sharply ordered Ned as Bob crawled
+out on deck. Then the commander of the balloon disappeared below.
+</p>
+
+<p>
+There were almost immediately several sharp, muffled explosions, and
+then the white propeller began to turn. The balloon was drifting
+quickly toward the northwest and rising&mdash;Bob could see its shadow
+following on the sandy plain. Then the arms of the propeller turned
+faster and faster and a velvet whirr in the cabin showed that the
+engine was falling to work. As the propeller blades settled into a
+steady hum the vibration of the car indicated increased speed. This
+Bob could also detect from the more swiftly flying shadow.
+</p>
+
+<p>
+The shadow was also growing smaller, and this meant that the Cibola
+was still ascending. Now the shadow paused and turned. Alan had
+thrown the rudder over and the balloon had responded instantly. The
+aeroplane arms stretched out horizontally on each side of the car.
+Ned, reappearing, took a quick look at the altitude gauge and again
+disappeared. The aeroplane arms dipped in front almost forty-five
+degrees and the current, blown back by the propeller, struck them
+with a jar. The craft again responded and slowly took a downward
+slant.
+</p>
+
+<p>
+Propeller, rudder and aeroplane being at work, Ned again appeared.
+</p>
+
+<p>
+"Go below," he ordered sharply, "and bear a hand when needed."
+</p>
+
+<p>
+Bob did so. Alan was on the pilot platform with his hands on the
+wheel controlling the rudder wires. His eyes were fixed straight
+ahead.
+</p>
+
+<p>
+"See that lever," he said, jerking his head to the left.
+</p>
+
+<p>
+Bob quickly discovered the aeroplane guider control and sprang to
+it.
+</p>
+
+<p>
+"Wait for orders," added Alan.
+</p>
+
+<p><br /><br /><br /></p>

+<h3>
+CHAPTER XIX
+</h3>
+
+<h3>
+THE FIRST FLIGHT
+</h3>
+
+<p>
+The balloon was still sliding downwards and swiftly forward. For
+several minutes the three boys stood in silence. Only the steady
+whirr of the engine and a musical humming of vibrating wires could
+be heard. Bob wondered if they were headed earthward again, for he
+could see the approaching foothills widening out beneath. At last,
+when they could not have been over five hundred feet from the
+ground, came the quick order:
+</p>
+
+<p>
+"Right the planes."
+</p>
+
+<p>
+Bob was almost caught napping, for he was busy looking through the
+window. But his hands responded instantly, and he almost choked
+with chagrin to find that he had started to throw the lever the
+wrong way. But his recovery of himself was instant and with a
+desperate pull he forced the guiding planes back horizontally. The
+glide downward stopped and the Cibola shot forward with renewed
+speed.
+</p>
+
+<p>
+On the bridge Ned held a fluttering chart before him.
+</p>
+
+<p>
+"How is she heading?" he called to Pilot Alan at the wheel. With a
+glance at the compass before him Alan promptly responded:
+</p>
+
+<p>
+"Nor'nor'east."
+</p>
+
+<p>
+"Make it north by east."
+</p>
+
+<p>
+A quick slight movement and a strain told that the alteration had
+been made.
+</p>
+
+<p>
+"North by east it is," sang out Alan.
+</p>
+
+<p>
+"Keep her there," was the echoing response.
+</p>
+
+<p>
+Bob was thrilled. Every word was to him a joy. Everything had
+happened so quickly that he hardly knew what it all meant, but he
+was happy. Even the sudden discipline pleased him and he was glad
+to be a part of it. The knowledge that a younger boy was giving him
+orders did not bother him. He had skill in his own line, but he saw
+and realized that in the Cibola Ned Napier was in charge and meant
+business.
+</p>
+
+<p>
+For some time then no word was heard. The Cibola, speeding, swiftly
+onward, had crossed the low foothills and was pulling herself
+through the almost breezeless air like a modern liner, five hundred
+feet above the ground. She was holding her course beautifully.
+Then Ned appeared and tested the gas exhaust and oil feed of the
+engine.
+</p>
+
+<p>
+"Were you ever in a balloon before?" he said when he had finished,
+turning sharply towards Bob.
+</p>
+
+<p>
+"Never," answered Bob, glad enough for a chance to say something.
+</p>
+
+<p>
+"Have you any matches?" somewhat sternly asked the commander of the
+Cibola.
+</p>
+
+<p>
+"Sure," replied Bob reaching in his pocket and finding one.
+</p>
+
+<p>
+"Any more? All of them."
+</p>
+
+<p>
+Surprised, Bob searched his clothes and discovered a few more which
+he obediently handed over to his superior officer. Noting the look
+of surprise in the reporter's face Ned laughed.
+</p>
+
+<p>
+"The first rule in a balloon is 'No fire.' But beginners forget,
+sometimes; we can't take this chance with you."
+</p>
+
+<p>
+"Take anything I have got," answered Bob with his old smile, which
+had now been in eclipse for some time, "and if I can speak at last I
+want to say that you boys are white, clean white, through and
+through. Didn't you need that ballast?"
+</p>
+
+<p>
+"We may need it badly," said Ned, laughing. "If it should become
+necessary I suppose you won't mind if we throw you overboard."
+</p>
+
+<p>
+"No," retorted Bob, "not if it is a little at, a time. But you're
+bricks&mdash;both of you&mdash;if I thank you I'll cry." The tears were again
+in his eyes.
+</p>
+
+<p>
+"Well, it wasn't the thing to do, I suppose," said Ned turning away,
+"but you looked so hungry to go, and I knew what it meant. So I
+thought we'd just give you a little ride up to the camp."
+</p>
+
+<p>
+"Yes, of course," answered Bob slowly as his hopes fell. "Put me
+out wherever you like," he added.
+</p>
+
+<p>
+"You can go up now and have a look around," said Ned at last, "both
+of you. I'll take the wheel."
+</p>
+
+<p>
+The relieved boys scrambled onto the bridge deck. Night was coming
+on and the mountains to the west were already black. Evening
+shadows were lengthening on the sloping plains beneath and a gentle,
+rising breeze flapped the flag and pennant and swayed the bag above
+them. Beneath, the Chusco wound its half dry course and off to the
+east a blue haze, melting into the unending sand, told of a treeless
+and waterless waste.
+</p>
+
+<p>
+"And there," exclaimed Alan at last, pointing off to the northwest
+where snow-capped, ragged peaks rose out of a black jumble of
+mountains, "are the Tunit Chas and the land of our dreams.
+To-morrow&mdash;"
+</p>
+
+<p>
+"One moment," interrupted Bob quickly. "I think you are forgetting.
+That is your secret and not mine."
+</p>
+
+<p>
+Alan flushed. "I forgot," he said with a stammer, "and I thank
+you."
+</p>
+
+<p>
+"I can't afford to make you sorry you brought me," added Bob, "and
+you are not going to be."
+</p>
+
+<p>
+There was a little jar. The propeller slackened a trifle, and Alan
+explained that Ned had headed the Cibola another point into the
+freshening breeze.
+</p>
+
+<p>
+"Steward," said Ned from below, "it's seven o'clock and I'm hungry.
+Besides, it's getting pretty dark down here."
+</p>
+
+<p>
+Alan and Bob looked at each other and laughed.
+</p>
+
+<p>
+"That certainly means me," exclaimed Bob, and both boys clambered
+below. With Alan's help Bob made his first examination of the store
+room.
+</p>
+
+<p>
+The meal was rather haphazard, as the boys, carried away by the
+excitement of their new flight, had neglected to eat when it was
+light. But water and hardtack were easily accessible, and Alan,
+taking the first two cans at hand, found happily that they contained
+sardines and veal loaf.
+</p>
+
+<p>
+"We'll eat on deck," suggested Ned, as he set the wheel and had
+another look at the engine, which had not missed a revolution.
+</p>
+
+<p>
+The night that greeted them was magnificent. The moon was not yet
+up, but the stars were scintillating in the inky sky and the deep
+silence of the clouds and desert was about them. Bob gazed as if
+spellbound. The charm of the night appealed to him as it did to Ned
+and Alan; but with it his brain formed phrases&mdash;"cloudland by
+night," "a dash to the stars." The reporter in him was thinking
+"copy."
+</p>
+
+<p>
+"Hey, there, wake up!" cried practical Ned.
+</p>
+
+<p>
+Bob flew to his task; with a turn he had the veal loaf can open and
+had dumped its contents in the wooden plate held by Alan.
+</p>
+
+<p>
+In another moment he would have thrown the empty can overboard but
+the watchful Ned, ready for another lesson in aeronautics, caught
+his hand.
+</p>
+
+<p>
+"Don't you like the route we are taking?" laughed Ned.
+</p>
+
+<p>
+Bob's face showed he did not understand.
+</p>
+
+<p>
+"The loss of the weight of that can might send us sparing upward a
+thousand feet," explained Ned dryly, "so don't cast over ballast
+until you get orders."
+</p>
+
+<p>
+Bob shook his head. "Well doesn't that beat all," he exclaimed.
+</p>
+
+<p>
+As night fell and the air grew heavier, the barometer showed that
+the Cibola had a tendency to rise. The aeroplanes were readjusted
+and then for an hour the craft sped on untouched. At eight o'clock
+Ned said:
+</p>
+
+<p>
+"We haven't traveled over eighteen miles in an hour and we've been
+afloat four hours. If we are still over the Chusco and Elmer and
+Buck are at the appointed place we may be within ten or twelve miles
+of them."
+</p>
+
+<p>
+"They are going to burn three small camp fires set in a triangle,
+you remember," remarked Bob.
+</p>
+
+<p>
+"Therefore," suggested. Ned, "all keep a sharp lookout."
+</p>
+
+<p>
+At half past eight Ned showed some concern. No lights had been
+sighted and the reckoning showed that they must be within two or
+three miles of the probable location of the camp. Another fifteen
+minutes went by, and yet no signal fires were seen. They had now
+passed over the junction of the two rivers, if their calculations
+were right, and Ned and Alan were in a quandary.
+</p>
+
+<p>
+"It's no use to go on," commented Ned; "so we'll just make a wide
+circle and see what we can find."
+</p>
+
+<p>
+It was also useless to look below. In the darkness there was no
+sight of either river or desert.
+</p>
+
+<p>
+"It we don't pick them up in that way," continued Ned, "we'll
+descend and tie up for the night."
+</p>
+
+<p>
+Both Ned and Alan went below, and with the engine shut down to half
+speed the Cibola was turned on her course in a wide sweep. Bob
+alone watched with anxious eyes, until he was joined in a short time
+by Ned. There was no sound but the soft chug-chug of the engine,
+and for some time neither spoke. The breeze of the early evening
+had died and there was not a breath of air. Alan in the dark cabin
+below held the wheel and Ned and Bob alone, hanging over the side
+net, watched and listened in vain.

+<h3>
+CHAPTER XX
+</h3>
+
+<h3>
+FIGHTING INDIANS WITH A SEARCHLIGHT
+</h3>
+
+<p>
+"Stop her!" It was Ned's voice in quick command. The young
+aeronaut, peering over the side of the car of the Cibola into the
+black night, had suddenly seen something that prompted the order.
+It was a distant flash of light. This was followed by an echoing
+explosion. The other boys heard the explosion and all instantly
+knew that it was a shot from a firearm. Almost before Alan could
+shut off the power Ned had disappeared into the cabin to help head
+the balloon in the direction of the spurt of fire. The Cibola
+slackened speed and they waited, drifting slowly toward the east.
+Then, suddenly, and almost together came two streaks of fire and two
+more explosions.
+</p>
+
+<p>
+"One of them might mean a signal," said Ned gravely, "but they were
+not from the same spot. If it were Elmer he would have the three
+fires. If it is Elmer and Buck and they can't make a fire and are
+shooting I am afraid it means trouble."
+</p>
+
+<p>
+"It may mean Indians," suggested Bob, "and they may have put out
+their fires for safety."
+</p>
+
+<p>
+"They might even be holding off an attack of some kind," added Alan
+anxiously.
+</p>
+
+<p>
+Just then there was another crack of a firearm now a little nearer.
+The Cibola was drifting directly toward the sound, but very slowly,
+and would soon have lost all headway.
+</p>
+
+<p>
+"I don't want to be presumptuous," said Bob in a low voice, "but
+can't we land and find out what the trouble is?"
+</p>
+
+<p>
+"We can find out without landing," replied Alan.
+</p>
+
+<p>
+It was so dark in the cabin that the boys could only dimly see each
+other, but Ned was groping about near the silent engine. In a
+moment he had secured from the ammunition case a storage electric
+light, and cautiously shading the lens with his cap he asked Bob to
+hold it. Then he turned to his chum.
+</p>
+
+<p>
+"I didn't know just how we would use our little drop light," he
+began; "but it seems that the idea wasn't half bad. There is a
+tribe of Indians not far from here that would steal a horse or cut a
+man's throat quickly enough&mdash;the renegade or Southern Utes." As he
+spoke he was digging in a chest extracting various small parcels.
+"Not even the other Indians have any use for the Utes. And there is
+only one thing to do. We must first find out if our friends are
+below."
+</p>
+
+<p>
+With the help of the flashlight Bob could we that Ned held in his
+hand a large, high candle-power incandescent bulb and was adjusting
+it in a silver reflector.
+</p>
+
+<p>
+"With an electric light?" exclaimed Bob.
+</p>
+
+<p>
+"Why not?" replied Ned. "And the help of our little dynamo."
+</p>
+
+<p>
+Ned took the flashlight, held it under his coat, and crawled around
+in front of the silent engine. "It's here," he explained for Bob's
+benefit, "and I am just throwing the gear onto the propeller shaft."
+</p>
+
+<p>
+"Well, if you are afraid to show this little light why aren't you
+afraid to show a brighter light?" asked the observing reporter.
+</p>
+
+<p>
+Alan answered him.
+</p>
+
+<p>
+"We are only afraid because it might draw an attack from some
+observer. Balloonists are never safe from meddlesome persons or
+worse. But there isn't the same danger if the light isn't on the
+balloon."
+</p>
+
+<p>
+"Sure," said Bob. "I understand that. But you can't hold it very
+far away."
+</p>
+
+<p>
+"No," answered Ned, "that's why we braided two good copper wires in
+our drag rope." As he said this he opened the trap door in the
+floor of the cabin and feeling about in the dark soon had hold of
+the coiled drag.
+</p>
+
+<p>
+"I guess I'm dull," began Bob.
+</p>
+
+<p>
+"No," interrupted Alan, "only you haven't given two or three years
+to figuring out the possibilities of an air ship."
+</p>
+
+<p>
+Ned was attaching the bulb, reflector down, to the end of the rope.
+</p>
+
+<p>
+"That rope is three hundred feet long. A light at the end of it is
+quite a way from our bag.
+</p>
+
+<p>
+"Oh, I see," exclaimed Bob at last. "If we find Indians and they
+shoot at our searchlight they are pretty sure to miss us."
+</p>
+
+<p>
+"That is the theory," answered Ned.
+</p>
+
+<p>
+And then the plan in Ned's mind was explained. The engine was to be
+started at quarter speed, which meant that the sound would be
+imperceptible; and, lying on the floor of the cabin, Ned was to
+direct the movements of the ship, with Alan at the rudder wheel and
+Bob at the aeroplane guider.
+</p>
+
+<p>
+"A quarter to ten o'clock," said Ned glancing at his watch as he
+shut off the concealed flashlight, "and now start her up."
+</p>
+
+<p>
+As Alan started the engine and it began to turn the propeller they
+could tell by the light breeze that the car was moving again, but
+very slowly. The other boys could also hear Ned delicately paying
+out the long drag rope. At last it was all out. Then Ned crawled
+forward again to the dynamo and up to the partly open floor of the
+car and whispered that he was ready. The multiple gear was already
+speeding the little generator swiftly.
+</p>
+
+<p>
+"Lie down on the floor and watch," murmured Ned softly, "I'm going
+to turn her on."
+</p>
+
+<p>
+Alan and Bob did so. As their two heads filled the open trap in the
+cabin floor there was a click and then, as if some necromancy had
+focused the sun on a part of the darkened world, a circle of light
+seemed to spring out of the desert beneath. Yellow, with here and
+there a ragged rock and a sage brush or two, the shadows of the
+rocks and brush black like spilled ink, and the sand glaring back at
+them with almost quivering brightness, the circle shot back and
+forth as the light followed the swinging rope. But no living thing
+was in sight. A click and all was black again.
+</p>
+
+<p>
+"Nothing doing," exclaimed Bob.
+</p>
+
+<p>
+"Wait," suggested Ned, "persons we couldn't see may have seen them."
+</p>
+
+<p>
+Almost as he spoke there was another quick report.
+</p>
+
+<p>
+"Did you see the flash, Alan?" asked Ned eagerly, for he had been
+busy with the dynamo.
+</p>
+
+<p>
+But Alan was already at the wheel, and again the car swung from its
+course.
+</p>
+
+<p>
+"Wait," he exclaimed, "turn it on again when I give the word."
+</p>
+
+<p>
+After perhaps two minutes he gave the signal and again Ned flashed
+the gleaming bulb. Again the circle sprang apparently out of the
+black ground. As the car drifted forward the black blotched golden
+sand ran the opposite way like a whirling panorama. A coyote
+sprang, dazed, from a clump of bushes and back again, but that was
+all.
+</p>
+
+<p>
+"Give him another chance," whispered Alan, and the light flashed
+out.
+</p>
+
+<p>
+"Listen," exclaimed Bob breathlessly, "wasn't that a cry?"
+</p>
+
+<p>
+Another moment and the sound came again.
+</p>
+
+<p>
+"Elmer!" exclaimed the two air ship boys together.
+</p>
+
+<p>
+The Cibola swung instantly at Alan's quick touch. Again the light
+flashed. Sand and rock and brush. The brilliant circle of light
+shot here and there, but the anxious watchers saw sign of neither
+friend nor foe. Then like a flash the level plain dropped into the
+sudden slope of a coulee and the darker shadow of water blotted out
+the glare of sand.
+</p>
+
+<p>
+"The river," whispered Ned. "Now watch sharp."
+</p>
+
+<p>
+As the light was blotted out this time Alan swung the wheel again.
+He knew instantly that they were on the wrong track, as they were
+going east and crossing the Chusco. Elmer and Buck would not cross
+the river. The camp was to be on the west side.
+</p>
+
+<p>
+"Follow the river," ordered Ned quickly; "the west shore."
+</p>
+
+<p>
+In order that the Cibola might be laid on the new course Ned threw
+on the light switch again. As he did so and the light flashed there
+was the sharp crack of a rifle and the light was gone.
+</p>
+
+<p>
+"Turn her on," exclaimed Alan; "I want to get a line on the river
+bed."
+</p>
+
+<p>
+Ned laughed. "I'll need a new bulb first. Some one down below
+turned it off."
+</p>
+
+<p>
+"What?" exclaimed the other boys together.
+</p>
+
+<p>
+"Shot out," calmly retorted Ned.
+</p>
+
+<p><br /><br /><br /></p>
+
+<p><a id="chap21"></a></p>
+<h3>
+CHAPTER XXI
+</h3>
+
+<h3>
+A CORDITE BOMB AND ITS WORK
+</h3>
+
+<p>
+In a moment the boys were hauling in the rope and Ned was back in
+the cabin after a new bulb which he secured and attached in the
+dark.
+</p>
+
+<p>
+"Now give her a swing," he said as Bob again lowered the rope. "It
+will make it harder to hit."
+</p>
+
+<p>
+When Bob announced that all the rope was paid out Ned snapped the
+switch again. In spite of the gravity of the situation all the boys
+were tempted to laugh. A brilliant green glow shot down. An
+emerald circle of light flooded the ground beneath.
+</p>
+
+<p>
+"If anyone sees that they'll sure think it's a drug store,"
+suggested Bob.
+</p>
+
+<p>
+"'Or a sign of the Great Spirit, perhaps," added Ned soberly, "it
+may help us in more ways than one, if Indians are&mdash;"
+</p>
+
+<p>
+"Look," hoarsely shouted Alan, "there, over there!"
+</p>
+
+<p>
+But his words were superfluous. The three boys saw the same thing.
+And then as the wide swaying of the bulb swept the gnome-like
+picture in green from view Ned threw himself over and shut off the
+engine.
+</p>
+
+<p>
+Not a hundred feet beneath the brilliant bulb the precipitous bank
+of the river had again shot into the circle of light. At the very
+edge of the cliff stood the big freight wagon. Behind it, between
+the wagon and the steep river bank, stood two horses. At one end
+two more lay prostrate on the ground. In front a light barrier of
+boxes and barrels rose a few feet from the ground. And there, a
+rifle at his shoulder, knelt Elmer Grissom, their friend and
+servant. Buck was nowhere in sight.
+</p>
+
+<p>
+Their worst fears were realized.
+</p>
+
+<p>
+As the dramatic picture flashed from view each boy knew that it was
+time to act.
+</p>
+
+<p>
+"What's to be done?" exclaimed Alan, his voice choking.
+</p>
+
+<p>
+"There can't be many of them," answered Ned finally, as if thinking,
+"or they would pushed their attack. If we could locate them the
+rest would be easy. Let Bob take the wheel and try to get over the
+wagon again; I have an idea."
+</p>
+
+<p>
+The Cibola again answered the rudder and circled, Ned flashing the
+bulb until the river came beneath them. This required but a few
+moments, but, before the craft had gathered momentum on the way
+back, there were four shots almost together about three hundred
+yards to the right of where they supposed the wagon stood, and a
+quick reply from the river bank.
+</p>
+
+<p>
+"Our light did it," exclaimed Alan, "they are rushing the
+barricade."
+</p>
+
+<p>
+"Indians don't rush together, if it is Indians," replied Ned. "Keep
+on up the bank, Bob. It's risky for Elmer," he added with a husky
+voice, "but we've got to take chances."
+</p>
+
+<p>
+Again the light flashed. Ned and Alan hurried to the bridge.
+</p>
+
+<p>
+Within its circle and almost together, sealing the seamed and hard
+bank of the river, were five dark figures. As the powerful light
+encircled them the crouching figures sprang backwards. But they
+were not quicker than the alert and prepared Ned Napier. A small
+round object shot downward from his hands. The glare of flame as
+the missile struck true and the thunderous roar that hurled the big
+bag of the Cibola sideways told that the cordite bomb had done its
+work well.
+</p>
+
+<p>
+Bob was speechless. Ned and Alan were already in hurried
+consultation. They could not count on fortunately finding the other
+besiegers all together, "'and there are at least four more," said
+Ned. The rescue of the lone besieged lad was not an easy problem.
+The boys believed themselves now just above the wagon again, but
+they were afraid to draw possible fire to the barricade by showing
+another light.
+</p>
+
+<p>
+The hurling of the bomb overboard had shot the Cibola heavenward
+like a bird. Before they realized it the aeronauts had mounted up
+at least two thousand feet. They then began maneuvering to regain
+their position. But this was not so easy. A flash of the suspended
+searchlight gave them not a trace of their bearings and it was
+plainly apparent they would have to use time and patience in
+recovering the location of the besieged wagon. Using their best
+judgment, they put the aeroplanes to work, and, circling slowly, the
+Cibola gradually came nearer and nearer to the ground. After ten
+minutes or more the car gave a sharp bound upward.
+</p>
+
+<p>
+"The drag has touched the ground," exclaimed Ned.
+</p>
+
+<p>
+The aeroplanes were righted, the engine was stopped, and again the
+balloon was drifting. There was not a sound to guide the aeronauts.
+The contact with the ground had broken the bulb and it was not
+replaced. For aught the rescuers knew they might be again directly
+over the wagon. Not a shot had been fired since the roar of the
+explosion, but there was no reason to believe that the yet living
+besiegers had withdrawn.
+</p>
+
+<p>
+"More likely planning a final attack," suggested Alan.
+</p>
+
+<p>
+Again a council was held.
+</p>
+
+<p>
+"We've got to take the risk," said Ned at last in desperation; "we
+can't do anything up here."
+</p>
+
+<p>
+And then, with Alan's approval, the propeller was set turning again,
+but so slowly that the big balloon was just moving under control.
+The aeroplanes were also set to bring the craft nearer the ground
+and, as a precaution, Bob was sent onto the bridge with an open
+knife to cut away ballast if sudden ascent were needed. The drag
+rope had been brought in. There were no means of knowing how near
+the car might be to the earth and the suspense was decidedly trying.
+</p>
+
+<p>
+"I guess I can come a little nearer finding out," exclaimed Ned
+finally to the others in a whisper.
+</p>
+
+<p>
+Alan did not know what he meant, but he resumed his place at the
+wheel. Ned had disappeared in the dark.
+</p>
+
+<p>
+"Where are you, Ned?" asked Alan anxiously at last.
+</p>
+
+<p>
+The answer came from beneath the car.
+</p>
+
+<p>
+"Only down here, but I'm going lower," Ned replied, again in a
+whisper. "Be ready with that ballast."
+</p>
+
+<p>
+A perspiration of fear broke out on Alan's body. He sprang to the
+open trap door.
+</p>
+
+<p>
+Just discernible in the darkness was Ned's slowly retreating form.
+</p>
+
+<p>
+He was climbing down the twenty-five-foot rope landing ladder with
+only his own strong grip and the spruce rungs to save him from
+death.
+</p>
+
+<p>
+There was nothing to be said or done. Bob did not know what was
+going on below, but he knew that he had a task set for him, and in
+the long silence that followed while the Cibola settled lower and
+lower and drifted on and on in the dark he stood, knife in hand, at
+the ballast bags.

+<h3>
+CHAPTER XXII
+</h3>
+
+<h3>
+A THRILLING RESCUE IN MID-AIR
+</h3>
+
+<p>
+Buck, the guide, and Elmer Grissom had reached their appointed
+rendezvous at two o'clock that afternoon. The hot journey had been
+tedious and uneventful. Only at the half-breed settlement twenty
+miles north of Clarkeville had they seen a human being. Therefore,
+after they had been in camp about an hour, even the vigilant,
+experienced Buck was startled to observe suddenly a solitary
+Indian&mdash;his horse as statuesque as himself&mdash;watching them from a
+knoll some two hundred yards distant.
+</p>
+
+<p>
+As the old scout raised both hands in signal of peace the Indian
+rode forward. The man was not in the Indian panoply of the old
+days, except that he wore moccasins and had two bands of red and
+yellow paint on his broad, dark face. A black wide-brimmed hat, a
+faded blue shirt and trousers completed his outfit.
+</p>
+
+<p>
+"How?" exclaimed the Indian.
+</p>
+
+<p>
+"Navajo?" answered Buck.
+</p>
+
+<p>
+"Ute!" came the answer. "Where go?"
+</p>
+
+<p>
+"Right here," said Buck good-naturedly, pointing to the ground.
+</p>
+
+<p>
+"Ute land!" retorted the Indian without a trace of expression in his
+face.
+</p>
+
+<p>
+"No," retorted Buck sharply, "not Ute land. Ute land there,"
+pointing north, "in Colorado."
+</p>
+
+<p>
+"Ute land!" exclaimed the red man again, this time scowling.
+</p>
+
+<p>
+Buck only shook his head.
+</p>
+
+<p>
+Then the Indian suddenly threw himself from his horse, strode to the
+wagon and threw up the tail curtain. Safely stored therein he saw
+the protected tins of gasoline.
+</p>
+
+<p>
+"Whisky?" he exclaimed.
+</p>
+
+<p>
+"No," laughed Elmer, "not whisky."
+</p>
+
+<p>
+"Whisky," repeated the stranger turning towards Buck; "drink!"
+</p>
+
+<p>
+But Buck shook his head.
+</p>
+
+<p>
+With out another word the Ute walked haughtily to his horse, threw
+himself upon it, and, clasping his heels to its sides, rode quickly
+away.
+</p>
+
+<p>
+"I'm sorry," exclaimed the veteran at last.
+</p>
+
+<p>
+"I had no idea that there were Utes around here."'
+</p>
+
+<p>
+"He doesn't seem dangerous," commented Elmer.
+</p>
+
+<p>
+"No," answered Buck, "men who'd cut your throat for a horse never
+do. The chances are he isn't alone."
+</p>
+
+<p>
+Elmer looked up in surprise.
+</p>
+
+<p>
+"We'll just make sure," exclaimed Buck, making as light of the
+affair as possible. "I don't want to lose my horses and you don't
+want to lose your freight. We'll make ourselves ready in case our
+friends come back to make us a little visit."
+</p>
+
+<p>
+And as night came on and Elmer helped Buck draw the wagon close to
+the river bank, where approach from the rear would be difficult, the
+boy began to realize what it meant to get away from the telegraph
+and policemen and law and order. And when the experienced scout
+unloaded a portion of their heavier freight and began to build a
+small barrier Elmer's usual joviality cooled into silence. The
+three piles of brush and driftwood from the river were laid out some
+distance in front of the camp in preparation for the agreed signal
+fires and then, before the sun went down, the scout and his
+companion made their camp fire and had supper.
+</p>
+
+<p>
+"What do yo' expec' dey'll do?" asked the colored lad at last.
+</p>
+
+<p>
+"Well, you can't tell. Injuns are puzzles. When they steal they
+steal in the dark. When they fight they fight at daybreak."
+</p>
+
+<p>
+"What do yo' suggest?"
+</p>
+
+<p>
+"To tell the truth, son," answered Buck, "there ain't much to do but
+keep yer eyes open and pop it to the first red horse thief ye see
+crawlin' around in the night."
+</p>
+
+<p>
+"Hadn't we better light our signal fires?" asked Elmer.
+</p>
+
+<p>
+"There won't be any signal fires to-night," replied Buck, slowly,
+"if you want my advice. It's one thing for a bluffin' Ute to walk
+up in the daylight when you've got a fair chance to give him as good
+as he sends, and its another thing for him to get a bead on you a
+sittin' in the light o' yer camp fire&mdash;him in the dark."
+</p>
+
+<p>
+Elmer saw and understood.
+</p>
+
+<p>
+So night fell in silence with Buck and Elmer keyed up and ready to
+meet any possible attack.
+</p>
+
+<p>
+Nothing happened until several hours had passed. Neither Elmer nor
+Buck were any the less alert, however. The old scout was pacing up
+and down in front of the barricade and perhaps a hundred feet from
+it. Elmer could just hear his soft footfalls in the sand. Suddenly
+these ceased. Almost at the same moment there was the crack of
+Buck's rifle, a groan and a moment later the scout was inside the
+barricade.
+</p>
+
+<p>
+"I guess I got him all right," he whispered, "he was makin' too much
+noise."
+</p>
+
+<p>
+This was the shot Ned heard miles away in the Cibola.
+</p>
+
+<p>
+Again for some minutes there was no sound and then, suddenly and
+from the left, came a spit of flame in the dark. Almost before
+Elmer heard the explosion Buck's gun had spoken in reply. Both
+bullets went wild, but Buck explained that it was necessary to give
+shot for shot, "and right at 'em," said Buck, "as it takes a little
+o' the ginger out o' them."
+</p>
+
+<p>
+But the besiegers had undoubtedly widened out. The next signs of
+them were two shots, almost together. Elmer's rifle made quick
+reply, but, to the boy's surprise, Buck failed to fire in return.
+The scout had disappeared from his companion's side. Before Elmer
+could call out he heard a rush at the end of the barricade, and then
+two explosions almost together and not ten feet away. He could not
+describe the sound that followed, but he knew that it meant the
+convulsions of human beings in agony. He whispered his companion's
+name, but there was no answer&mdash;only a gasp.
+</p>
+
+<p>
+In the black darkness the colored boy, revolver in hand, crawled
+forward. At the end of the barricade Buck's body was lying. As the
+boy's hand fell on the old man's breast he knew that it was blood he
+felt.
+</p>
+
+<p>
+"Buck," he whispered, "Buck! Is yo' hurt?"
+</p>
+
+<p>
+He put his arm under his friend's head. For a moment the unconscious
+form yielded and then convulsively straightened. Elmer knew that his
+companion and protector was dead.
+</p>
+
+<p>
+With strength that he did not know he had Elmer laid Buck's dead
+body behind the little wall of freight boxes.
+</p>
+
+<p>
+Then, as if by intuition, he sprang forward and found what he
+suspected&mdash;the unmoving form of an Indian. Unable to see, Elmer
+quickly felt over the adjacent ground with his hands and discovered
+the dead Ute's rifle. The revolver was gone. In the same manner he
+recovered both Buck's rifle and revolver, and then prepared to do
+his duty&mdash;to protect his employer's goods so long as he could.
+</p>
+
+<p>
+He was scarcely entrenched again, with the three magazine rifles
+laid on the barricade before him, when his straining ears heard a
+new sound. Far away and faint, but meaning only one thing, the soft
+chugging of a motor. The Cibola! There could be no doubt of it.
+The instant feeling of relief was shattered even as it gave Elmer
+new courage; to attempt to light the signal fires would probably
+mean instant death. And without them how would his friends know his
+position or peril? But one thing he could do; and even knowing that
+it would mean an answering shot from the skulking horse thieves he
+discharged his revolver into the air.
+</p>
+
+<p>
+Then the sound of the motor died away and the long minutes dragged
+by. When it began again, and more softly, the sound was nearer.
+Nearer, and nearer it came and then the circle of light fell on the
+wagon and was gone. "At least they know where I am," thought Elmer
+to himself, and settled down courageously for renewed attack,
+determined to hold out to the last. At this moment came the shot
+that put out the Cibola's light.
+</p>
+
+<p>
+The nervy boy had been tempted to abandon the wagon and follow the
+light, but his second judgment was against this. "If they can, the
+boys will come back," he argued, "and I'll only get out of this when
+I have to."
+</p>
+
+<p>
+To Elmer's surprise the attackers had been strangely silent for some
+time. With more experience he would have known that this meant even
+greater danger, but he only hoped it was due to the distracting and
+mysterious flying light. Then the sepulchral green light burst out
+in its funnel-like volume. It was coming back. It flared, went
+out, shot over the distant sands again like a searching' eye and
+then began moving straight up the river bank towards the wagon.
+Then came the earth rending explosion. Nor could the besieged boy
+know even then that Ned's well-aimed bomb had sent five Utes to
+their last sleep.
+</p>
+
+<p>
+When the sound of the explosion had died away and Elmer had
+recovered himself&mdash;for the shock had thrown him forward on the
+barricade&mdash;the whirr of the Cibola's motor was again far away. But
+it was directly above him!
+</p>
+
+<p>
+As if the attackers had been paralyzed by the explosion, the long
+interval continued without a shot. Then suddenly, from the right
+and left and front, the real attack began. One shot sounded as a
+signal, and then from a half circle before him half a dozen bullets
+tore their way towards the boy and his barricade. Most of them went
+wild. Two hit the boxes and half stunned the lone guardian behind
+them. The assailants did not know that one of the two white men was
+dead, and Elmer, in hopes temporarily to deceive them, fired two of
+the rifles at the same moment.
+</p>
+
+<p>
+But his enemies were closing in; the half circle was growing smaller
+and the crash of the bullets in the wagon above him and in the
+barricade in front told the boy that the end could not be far away.
+To the right in the direction of the explosion there was a gap in
+the fast closing circle. It was folly to delay longer. If escape
+were possible, it was in that direction. He would make one
+desperate attempt. One shot remained in his rifles. Putting it
+where he thought it would do the most good, and catching up the two
+yet full revolvers, the colored boy crawled under the wagon and
+crept hastily along the river bank.
+</p>
+
+<p>
+And yet he did not dare to attempt to pass the end of the Indian
+semi-circle. It was one chance in a thousand. Throwing himself on
+the ground, he waited. "Crack!" It was the rifle of an Indian, not
+fifty feet away and coming nearer. The stealthy footfalls told
+Elmer that his foe was heading straight for the river bank and that
+he was in the Ute's path. Then he could hear the Indian's deep
+breathing. Detection was inevitable.
+</p>
+
+<p>
+One last thing remained to be done&mdash;to kill the Indian and make a
+dash forward down the river bank. And he must act before his foe
+discovered him. Elmer's revolver flashed fire and he saw his foe of
+the red and yellow face bound into the air and then topple forward
+with a cry of anguish.
+</p>
+
+<p>
+The boy turned, but too late. Directly in front he heard the sudden
+shouts of other Indians. The river at his back! Flight down its
+cement-like bank was impossible. He might plunge forward and pray
+that the water was beneath.
+</p>
+
+<p>
+The death cry of the man he had shot and the echoing yells of the
+Indians behind him had been taken up by others. He knew the
+determined savages were making a final rush. Indian cries seemed to
+come from the very ground at his feet. He hesitated no lodger.
+</p>
+
+<p>
+As he turned to the river a sudden and strange wave of cool air
+struck down on him from above. Without reasoning he paused. That
+pause saved his life. In that swift moment he heard the low creak
+of something straining. His eyes pierced the black about him. Was
+it a shadow? Something was brushing by him like a great bird asleep
+on the wing. Then it was on him.
+</p>
+
+<p>
+"Ned?" It was only a whisper but it was enough.
+</p>
+
+<p>
+"Elmer, here, quick!"
+</p>
+
+<p>
+Even the whisper had brought an instant shot, but the colored boy
+had hurled himself toward the voice and an instant later a strong
+young arm was about the besieged lad.
+</p>
+
+<p>
+It was Ned Napier on the swaying ladder of the Cibola.
+</p>
+
+<p>
+"Cut away," came the low quick order and before even the nearby
+besiegers could locate the sound Bob Russell, high above, had
+slashed the lashings of a bag of ballast. The big balloon sprang
+forward, Elmer dangling in the air, and then settled again to the
+earth as the desperate colored boy found the last rung of the ladder
+and clung fast opposite his rescuer.
+</p>
+
+<p>
+"Another, another," called Ned springing up the fragile length of
+the doubly laden ladder.
+</p>
+
+<p>
+A thud on the ground told where another bag of ballast had fallen.
+The crash of the fallen fifty-pound bag of sand probably saved the
+Cibola. Shot after shot poured in the direction of the sound,
+although the Cibola, dragging forward, yet refused to rise. Elmer,
+at the bottom of the ladder, was helping the car onward in low
+bounds by touching the ground with one foot.
+</p>
+
+<p>
+Then the air craft settled again. Elmer's weight was too much. A
+mad thought came into the boy's brain. The Indians had located the
+new invader and yells nearby told that hot pursuit was already being
+made. Then the spit, spit, of new shots showed the risk the boys
+had taken. Elmer realized it. Should he hang on and endanger the
+lives of his friends, or should he let go?
+</p>
+
+<p>
+There seemed no time to think, but the boy's hand had already
+loosened when out of the black came the hot breath of the foremost
+pursuer. As the savage sprang forward Elmer's free arm gave him a
+blow full in the face. At the same instant the Cibola sprang upward
+like a bullet. A volley of shots rang out below, but they were too
+late. The balloon had saved Elmer's life, and even before the lad
+had made his way up the swaying ladder into the cabin it was a
+thousand feet in the air.

+<h3>
+CHAPTER XXIII
+</h3>
+
+<h3>
+CAMP EAGLE IN THE MOUNTAINS
+</h3>
+
+<p>
+It seemed too wonderful to be true. But words were proof enough
+that Ned Napier and Alan Hope had found a new use for dirigible
+balloons. Faithful Buck's death was more than the loss of a
+companion. In the short time the boys had known him he had shown
+that under his rough frontier bearing he was a brave and honest man.
+</p>
+
+<p>
+"We can't go back now," explained Ned, "and we can't afford to land
+and wait for day. We can't all stay in the Cibola, and those of us
+who are landed must be left in a safe place. Our work," he
+continued turning to Bob, "is in the Tunit Chas Mountains, thirty
+miles west of here. It seems as if you had to know it. We'll go
+there to-night and land, if we can, on some isolated and inaccessible
+plateau. We'll make that our new relief camp and you and Elmer must
+take charge of it. To-morrow Alan and I will return in the Cibola to
+our abandoned wagon, bury Buck and bring away such of our stores as
+may be left. It's going to be a great loss, for I suppose the
+Indians have stolen everything. If the gasoline is gone it will cut
+short our work in the mountains."
+</p>
+
+<p>
+"I don't think it will be lost," said Elmer, quietly. "We tried to
+save it. We rolled it into the river."
+</p>
+
+<p>
+"But it will float away," exclaimed Alan.
+</p>
+
+<p>
+"Unless de tins caught on in de drift in de bend jes' below,"
+answered Elmer. "I seen four ob de eight tins dar befo' dark."
+</p>
+
+<p>
+"That's what I call genius," exclaimed Ned. "Elmer, you're a brick!
+And now our course is due east at half speed. By daybreak we'll be
+over the Tunit Chas. Until then, the rest of you turn in. I'll run
+the ship."
+</p>
+
+<p>
+Fifteen minutes later, despite the nerve-racking experiences of the
+momentous day, Alan, Bob and Elmer were wrapped in their blankets
+and sound asleep on the bridge deck of the Cibola.
+</p>
+
+<p>
+The night passed slowly, but Captain Ned stood the long trick at the
+wheel, happy and content. To feel the Cibola, the product of his
+youthful genius, at last moving forward in obedience to his
+slightest touch drove all thought of fatigue and sleep from him.
+</p>
+
+<p>
+But, above all, the early light of the coming day was to reveal to
+him a sight of the land of his hopes. There, before him, were the
+Tunit Chas; peaks and chasms of unsolved mystery wherein the
+centuries had held close their secret. Many trials had blocked his
+way. Was he now about to reap the reward of his labors? Did the
+hidden city of Cibola lie somewhere below him? Or were the Palace
+of the Pueblos and the Turquoise Temple but empty myths?
+</p>
+
+<p>
+The young aeronaut's present plans were simple enough. The Cibola
+had now been afloat twelve hours and nearly half her gasoline was
+exhausted. More than once in the night Ned had noticed that the
+balloon was settling lower and he had been forced to maintain his
+level by casting over ballast. It was apparent that they were
+already losing gas.
+</p>
+
+<p>
+In boyish impulse and sympathy they had made Bob Russell, the young
+reporter, a third and unexpected passenger, and accident had forced
+them to add Elmer Grissom, their colored friend and servant. And
+these extra occupants of the car must be landed at the earliest
+opportunity.
+</p>
+
+<p>
+This became imperative now because, the relief and supply station on
+the Chusco river having been destroyed, the Cibola must add enough
+ballast and gasoline to make its exploring tour in the mountains in
+one journey. The original plan had been to make quick dashes to
+the camp on the Chusco for gasoline and then return to the
+mountains. To provide for this new weight the two new passengers
+and a good portion of the air ship's stores must be landed. And the
+most feasible plan seemed to be to set up a new emergency camp in
+the heart of the mountains.
+</p>
+
+<p>
+Many things might happen to the now perfectly working balloon. And,
+even if cast away in the mountains, it was no part of Ned and Alan's
+plan to cease searching for the temple of treasure until dire
+necessity drove them from it. In case wreck and privation came it
+would be comforting to know that somewhere in the same wilderness
+food and friends awaited them.
+</p>
+
+<p>
+The first glow of the sun painted for the ever watchful pilot a
+picture beyond the possibilities of brush and canvas. Here and
+there out of the blackness below sprang rosy points, the sun-tinted
+peaks of the Tunit Chas. Down the mountain sides, like rivers of
+silver pink, fell the sun's light. Then the valleys began to open
+out of the chasm of night-dark canyons wrought in the wilderness of
+the mountain sides. Here and there, oases left by the devastating
+hand of time, rose high plateaus, tree-crowned and verdant. And
+then, higher up among the white peaks, sentinel-like, stood giant
+tables whose brown tops and precipitous sides told of inaccessible
+and arid wastes. "And somewhere," said Ned to himself, "in this
+Titanic chaos lies the object of our search."
+</p>
+
+<p>
+Starting at half speed, Ned had soon reduced the engine to quarter
+speed. When he aroused his sleeping companions Wilson's peak, their
+chief landmark, was just in sight far behind. His calculations
+placed the present location of the Cibola thirty miles from the
+Chusco river and just over the eastern Tunit Chas Mountains.
+</p>
+
+<p>
+"All hands turn to," shouted Ned cheerily, "and stand by to make a
+landing."
+</p>
+
+<p>
+There was a scramble, a rubbing of yet sleepy eyes and then an
+outburst of admiring wonder. The Cibola had sailed over two broken
+ridges enclosing an irregular, broken valley and was now looking
+down on a shelf-like plateau abutting on the second ridge and west
+of it. On three sides the plateau dropped precipitately into a
+lower rock-strewn, valley. On its eastern side it joined the still
+higher ridge. A pine forest crowned the top of the shelf-like
+mountain side and then ran up to the higher slopes until the carpet
+of green faded into the brown wastes of the timber line. In the
+very center of the wilderness of trees glistened a little lake of
+mountain water. From it the silver thread of a rivulet wormed its
+way for a mile or more among the trees and then trickled over the
+side of the cliff in a vapory waterfall.
+</p>
+
+<p>
+Ned had swung the Cibola into a wide curve and the balloon and car
+were soon directly over the mountain creek. He threw the aeroplane
+guides downward and the slowly moving car drifted lower until it was
+but four hundred feet above the water and the overhanging pines.
+Then, following the water course beneath, the air ship floated back
+into the woods and the little lake widened out beneath them. Two
+deer, at the water's edge, stood unalarmed. On the south of the
+lake a grassy opening indicated Ned's destination.
+</p>
+
+<p>
+"Here," he explained, "we can make a safe landing. It is an ideal
+place for a camp, with plenty of firewood and water."
+</p>
+
+<p>
+"And meat, too," interrupted Alan, pointing to the deer.
+</p>
+
+<p>
+"Venison and bear meat too, no doubt," laughed Ned.
+</p>
+
+<p>
+From the top of a dead pine tree an eagle rose and soared lazily
+away.
+</p>
+
+<p>
+"It's like the camping out places you read about," exclaimed Bob.
+"That eagle nest completes the picture."
+</p>
+
+<p>
+"It does," interrupted Ned, "and I hope you won't forget the
+picture. That high, barren tree is your landmark. Some day you may
+need it. Remember; from the valley below your camp can be found by
+locating the little waterfall on the cliff. From the timber line
+above you will know it when you see the eagle's nest. And now let
+go the anchor. We have no gas to spare, and can't afford to open
+the valve."
+</p>
+
+<p>
+To make a landing in a balloon without throwing open a valve and
+wasting precious gas is almost impossible. The craft could only be
+kept near the ground by keeping it in motion or by causing the
+propeller fans to depress currents of air on the aeroplanes.
+Therefore, as soon as the engine stopped, the Cibola would mount
+higher. But resourceful Ned had long since thought out this
+problem.
+</p>
+
+<p>
+The engine's speed was reduced and the anchor was quickly lowered
+until it caught hard and fast in a strong pine tree. The contact
+shook the fragile car and sent the bag bounding, but when it was
+seen that the iron had fixed itself firmly three of the boys,
+pulling on the anchor rope, gradually drew the great buoyant car
+down until it floated just above the tree top. To drag it lower
+was, impossible, for one sharp branch might injure the bag beyond
+repair.
+</p>
+
+<p>
+When the ship was safely anchored just above the tree, the
+twenty-five foot landing ladder was lowered and Ned himself made his
+way down its fragile rungs into the tree. .
+</p>
+
+<p>
+"Hold on tight," he continued, "I'm getting off."
+</p>
+
+<p>
+As he did so and found footing in the tree branches the Cibola
+tugged to free itself, as if, overjoyed to be rid of Ned's one
+hundred and forty-five pounds of weight. As soon as the young
+commander was safely on the ground he ordered the other boys to pay
+out the anchor rope and again the Cibola rose in the air.
+</p>
+
+<p>
+"Now," ordered Ned, "start your engine and head the car over the
+opening."
+</p>
+
+<p>
+While Ned stood below directing, with hands to his mouth,
+trumpet-wise, the Cibola strained at her anchor rope and then,
+obeying her rudder, moved directly over the open space, her nose
+pointing skyward at an angle of forty-five degrees.
+</p>
+
+<p>
+"Hold her," yelled Ned, "and haul back."
+</p>
+
+<p>
+The boys again strained at the taut anchor rope until the car stood
+just clear of the trees and some two hundred feet in the air.
+</p>
+
+<p>
+"Now lower your drag rope and an empty ballast bag," called Ned.
+</p>
+
+<p>
+While this was being done the navigator of the Cibola was busy
+carrying chunks of broken rock from the margin of the little lake,
+and in a short time the boys above were hauling away on the rope and
+lifting aboard new ballast. With each bag of it the Cibola sank
+lower and lower, until finally, when it was almost balanced in the
+air, Ned easily drew the balloon to the ground.
+</p>
+
+<p>
+But the landing was not yet finished. Not a passenger in the craft
+could step ashore until Ned had added more stone. But when enough
+of this had been lifted up to the hands above, and Elmer could
+alight, the two willing workers on the ground soon made it possible
+for the other boys to spring overboard. Then the four of them
+loaded enough more rock on the bridge to take the place of the
+stores to be landed.
+</p>
+
+<p>
+There were not many things that could be left: water, and half the
+provisions and, preserved goods; a few cooking utensils; blankets,
+an extra compass, two revolvers, a hatchet and saw; a light silk
+tent; matches and candles, a medicine case, ammunition, and, to make
+way for the gasoline that it was hoped might be recovered, all the
+extra oil on board&mdash;for the reservoirs yet contained an ample supply
+to make the trip back to the scene of Elmer's attack.
+</p>
+
+<p>
+At a safe distance from the balloon Elmer had returned to his
+favorite occupation. He got a fire going and while the other boys
+replaced the rocks on board with bags of sand from the margin of the
+lake the colored lad made hot coffee and broiled some bacon. It was
+a luxury after the cold, dry food of the long night.
+</p>
+
+<p>
+"When you come back this evening," exclaimed Bob jovially, "I'll try
+to have a juicy venison steak."
+</p>
+
+<p>
+"An' hot biscuits," chimed in Elmer.
+</p>
+
+<p>
+"And a good bed of balsam boughs," added Bob, "and a fine camp fire,
+and we can sit wound it and talk it all over."
+</p>
+
+<p>
+"And if we don't get back to-night you'd better have your camp fire
+anyway," said Ned.
+</p>
+
+<p>
+"Ain't you goin' to git back to-night?" ruefully interrupted Elmer,
+as he poured the smoking coffee.
+</p>
+
+<p>
+"You never know what you are going to do in a balloon," answered Ned.
+"If we can we will. If we can't we won't. If we are not back
+to-night we may not be here for several days. We've got work ahead
+now, and plenty of it."
+</p>
+
+<p>
+"We'll be here when you come," replied Bob earnestly, with a smoking
+bit of bacon in his fingers, "whenever that is."
+</p>
+
+<p>
+"No," replied Ned, "if we are not here in six days you must make
+your way out to civilization. You have food enough but you can't
+wait longer than that. As for directions, all I can say is that
+from this ridge back of us you can see across the half desert valley
+to the higher range of mountains. Should you cross the valley
+bearing almost due east and be able to get over or through that
+second ridge you will be able to see the top of Mount Wilson, thirty
+miles further east. From Mount Wilson it is fifteen miles southeast
+to the camp Elmer made. There you should pick up the trail of
+Buck's wagon back to the railroad eighty-five miles south."
+</p>
+
+<p>
+Bob's eyes opened.
+</p>
+
+<p>
+"Is it as bad as that?" he said half laughing. "We'll certainly
+have to get busy if the Cibola breaks down."
+</p>
+
+<p>
+"Or," went on Ned, "any strewn in the valley below here flows
+finally into the San Juan River to the north. If you can make your
+way to this river and then succeed in following its banks eastward
+until you reach the plains, some time or other you'll find a
+frontier settlement."
+</p>
+
+<p>
+"Or Utes," interrupted Alan.
+</p>
+
+<p>
+"Gib me de mountain road," exclaimed Elmer quickly.
+"Nomo'Utesfo'me!"
+</p>
+
+<p>
+"Yes," added Ned, "that's the trouble. The route to the San Juan is
+not only through a barren, broken mountain region, but it gets you
+finally right into the Southern Ute reservation. And, remember,
+too, that this is Navajo land. Your safety with them, should you be
+discovered, will be in diplomacy. And now good-bye&mdash;until we meet
+again."
+</p>
+
+<p>
+"And if we don't," replied Bob, huskily, taking the hands of the two
+boys in turn, "I just want to say again that you boys have done for
+me what I can't forget and what I can't repay. I don't know why you
+are here, and I don't want to know. What I've seen will never be
+revealed, when I get back to Kansas City and the Comet, until you
+tell me I am free to tell it. And you'd know what that means to me
+if you knew what a cracking good yarn my experience has given me
+already. Good-bye and good luck!"
+</p>
+
+<p>
+Ned and Alan clambered aboard; the rocks were cast overboard, and as
+the Cibola shot skyward the boys could hear Elmer calling:
+</p>
+
+<p>
+"Member, boys&mdash;we all'll be at Camp Eagle an' supper will be
+awaitin'."
+</p>

+<h3>
+CHAPTER XXIV
+</h3>
+
+<h3>
+A GRAVE IN THE DESERT
+</h3>
+
+<p>
+But Ned and Alan did not eat with their friends that night, nor for
+some days to come. And when they saw each other again one of
+Elmer's juicy venison steaks would have seemed to all of them the
+sweetest morsel ever eaten by man.
+</p>
+
+<p>
+Ned only waited to help inflate the balloonet in the big balloon
+with the little hand blower for the Cibola showed quite perceptibly
+the loss of gas after her twenty hours of inflation. Then, the
+course having been laid, he left the wheel and engine to Alan's care
+and turned in for his long needed rest.
+</p>
+
+<p>
+Alan had determined on a record flight. He allowed the Cibola to
+rise higher than it had yet flown, about 5,000 feet, and then
+setting the aeroplanes on a slight incline he headed the car on a
+down slant for Mount Wilson's just visible peak, thirty miles away.
+</p>
+
+<p>
+There was no economy in half speed, for time and the utilization of
+their gas were more precious than gasoline. "We can always float
+without gasoline," the boys had said to themselves, "but we can't
+move without gas." Therefore the Cibola was soon at its maximum and
+the enthusiastic Alan knew that Ned would have a short sleep.
+</p>
+
+<p>
+In an hour and twenty-one minutes the swift dirigible was abreast of
+the peak of Mount Wilson, and then, without slackening speed, Alan
+altered her course southeast toward the scene of the previous
+night's hair-raising experience. Long before he reached the place
+he was able to make the juncture of the two rivers his landmark, and
+the ship pointed her course as straight as a railroad train. After
+thirty minutes sailing from Mount Wilson, Buck's rendezvous could be
+made out, three miles beyond.
+</p>
+
+<p>
+One glance told the whole sad story. Two dead horses alone marked
+the spot where their freight wagon had stood. Alan aroused Ned, and
+as the Cibola sailed low over the place the boys saw that the
+thieving Utes had gone&mdash;with the wagon, horses, freight and their
+dead companions.
+</p>
+
+<p>
+Poor Buck's body was lying where the brave escort had fallen.
+</p>
+
+<p>
+"We can't make two landings," suggested Ned. "We'll find the
+gasoline and then come back and bury our friend."
+</p>
+
+<p>
+Disappointed, although they had really in their hearts expected
+nothing less, the young navigators turned the Cibola and sailed
+slowly down the river in the hope that the gasoline would be found
+where Elmer had described it as lying.
+</p>
+
+<p>
+They were as richly rewarded here as they had been previously
+disappointed. The drift, a tangled jumble of small mountain wood,
+had caught and preserved seven of their eight tins of gasoline.
+</p>
+
+<p>
+It was now noon, and broiling hot, but luncheon was not thought of
+and the difficult work of recovering the heavy packages was begun.
+This presented a new difficulty, for again the boys were determined
+not to lose any gas in making a landing.
+</p>
+
+<p>
+The drift was too light to hold their anchor although two trials at
+this were made. Not a bush or tree was to be found nearby. In
+despair at last, Alan was about to suggest opening the valve&mdash;for it
+was imperative that they secure the gasoline&mdash;when Ned turned the
+bow of the craft down stream.
+</p>
+
+<p>
+"Perhaps we can find anchorage further down," he explained.
+</p>
+
+<p>
+"But if will be pretty hard work carrying these tins," Alan began.
+</p>
+
+<p>
+"They floated where they are, didn't they?" smiled Ned. "What's the
+matter with letting them float a little further?"
+</p>
+
+<p>
+His hope was realized. But the solution was fully a mile away. On
+a sandy bar, half buried in the sand, the stout end of a cottonwood
+trunk, the flotsam of some extraordinary freshet, had come into
+view. The experience of the morning was repeated, but on a smaller
+scale, for here were no dangerous tree limbs to threaten their
+delicate silken bag. After two trials and much pulling and hauling
+the car of the Cibola was tied fast to the snag, half over the
+shallow water and half over the sand.
+</p>
+
+<p>
+Then, naked as when they were born, and suffering not a little from
+the pitiless sun, the boys started afresh. Alan made his way back
+up the river and began to prod out the stranded tin casks. All were
+soon bobbing along in the slow current, with Alan behind them like a
+lumber driver of the northwest dislodging logs left in the shallows.
+Ned below soon had all of them in shallow water.
+</p>
+
+<p>
+By means of a coil of the drag rope, looped in turn about the tins
+of recovered fuel, Ned lifting below and Alan pulling above soon
+transferred the gasoline to the bobbing Cibola. As each cask
+ascended, a portion of the extra ballast was dumped overboard.
+</p>
+
+<p>
+Then, dressing themselves and improvising what tools they could, the
+boys made their way sorrowfully to the scene of the previous night's
+tragedy. Buck's body was carefully removed and decently buried. A
+mound of boulders was made over the grave to designate the spot, and
+with the hope that some day they might return and suitably mark the
+desert tomb the boys took a mournful farewell.

+CHAPTER XXV

+
+<h3>
+BARTERING STORES A MILE IN THE AIR
+</h3>
+
+<p>
+"And now," said Alan, "it's ho, for Camp Eagle and our search at
+last."
+</p>
+
+<p>
+"I don't know about all that sentiment," answered Ned, thoughtfully.
+"I've been&mdash;"
+</p>
+
+<p>
+But he was interrupted. The boys, aboard the Cibola again, were
+just about to cast off when Alan cut short Ned's remark with an
+exclamation.
+</p>
+
+<p>
+"Isn't that a balloon?" he exclaimed pointing to an orange-like
+object high in the heavens toward the west.
+</p>
+
+<p>
+Ned caught up the binoculars and had a quick look at the rapidly
+moving ball which was rushing toward them from over the distant
+Tunit Chas Mountains.
+</p>
+
+<p>
+"No question about it," answered Ned, handing Alan the glasses; "a
+balloon, and a big one."
+</p>
+
+<p>
+"And out here, too!" commented Alan in surprise. "I guess the world
+is pretty small after all."
+</p>
+
+<p>
+"Everything ready?" asked Ned eagerly. And then as the retaining
+rope was untied from the frame of the car and slipped down and out
+from under the cottonwood snag the Cibola shot upward.
+</p>
+
+<p>
+"I have an idea," continued Ned, "and please don't object until you
+think it over. Let's make a little social call on the stranger!"
+</p>
+
+<p>
+"A call!" exclaimed Alan, plainly showing his astonishment; "a call
+on a balloon five thousand feet in the air?"
+</p>
+
+<p>
+"Certainly. We are going that high anyway. And we have the means
+of going where we like. If we go up until we strike the same,
+stratum of air the stranger is moving in we have our propeller and
+aeroplanes to check and guide ourselves. When it passes we can
+easily run alongside!"
+</p>
+
+<p>
+"Well, if that isn't the limit!" laughed Alan. "And I suppose we'll
+exchange greetings and messages like ships long at sea."
+</p>
+
+<p>
+"And," added Ned, "we can send some word to Major Honeywell. You
+can see our fast flying friend isn't going to stop around here."
+</p>
+
+<p>
+The Cibola was rising fast and the two air craft were coming closer
+and closer. As the dirigible reached the altitude at which the free
+balloon was sailing Ned put the aeroplane in operation, stopped the
+ascent of the Cibola and then, sweeping his own car into the same
+direction with the other balloon he reversed the propeller and held
+his own craft against the breeze until the stranger swept by.
+</p>
+
+<p>
+Then, throwing on the propeller again at full speed, Ned made the
+Cibola bound after the other craft, and in a few minutes, aided by
+the favoring wind, they were within hailing distance.
+</p>
+
+<p>
+Ned was on the bridge, his face flushed with the novelty of the
+race. A mile above the earth, the two air ships came closer until,
+as if running on parallel tracks, they were nearly together and
+abreast.
+</p>
+
+<p>
+"Balloon ahoy!" exclaimed Ned at last and in true maritime style.
+</p>
+
+<p>
+"The Arrow of Los Angeles, bound across the continent," came the
+sharp answer.
+</p>
+
+<p>
+"The Cibola from Clarkeville, New Mexico," called Ned in reply,
+"exploring. Please report us over Mount Wilson."
+</p>
+
+<p>
+Then the two ships of the sky came closer. The boys could see that
+the Arrow was well equipped for its purpose. Two determined looking
+aeronauts were leaning from the heavily laden car.
+</p>
+
+<p>
+"Need anything?" shouted the Arrow cordially.
+</p>
+
+<p>
+"In good shape," answered Ned, "but a little short on provisions."
+</p>
+
+<p>
+"Plenty here," came quickly from the Arrow, "glad to exchange
+fifty-pound emergency rations for ballast."
+</p>
+
+<p>
+"All right," responded Ned, "stand by to make a line fast."
+</p>
+
+<p>
+Alan, at the engine, brought the air ship up as skillfully as a
+pilot might a vessel, and as the two cars almost touched Ned passed
+the end of his drag rope, and the occupants of the Arrow with a
+quick turn made her basket fast to the bridge of the Cibola. There
+were handshakes, mutual congratulations and quick explanations. The
+Arrow, the property of a wealthy amateur balloonist, was attempting
+to sail, from the Pacific to the Atlantic and was, so far, beating
+the best calculation of her owner. In reaching the desired height
+that morning, however, much ballast had been used and the
+possibility of a renewed supply was jumped at.
+</p>
+
+<p>
+"These extra provisions were packed with the idea of possibly using
+them as ballast and we don't really need them. And, so," they
+explained to the boys, "if you do you had better take them and give
+us sand."
+</p>
+
+<p>
+The exchange was quickly made, and then, having stored their new
+food supply safely on the bridge, they said hasty farewells.
+</p>
+
+<p>
+Ned had scribbled this note on a page from his note book: "Major
+Baldwin Honeywell, Annex, Chicago. By courtesy of Balloon Arrow.
+Bourke, escort, killed by Indians. Search begins at once. Camp
+established on plateau, second range Tunit Chas Mountains, thirty
+miles due east Wilson's Peak. Greetings. Written 5,600 feet above
+San Juan River, New Mexico. Ned Napier and Alan Hope."
+</p>
+
+<p>
+The case of provisions weighed a trifle more than the ballast given
+in exchange, and as the line holding the two cars together was cast
+off the Cibola sank slowly below the level of the Arrow. Then, as
+the Cibola's engines began to push the car ahead in a wide turning
+circle, Ned called up to the disappearing Arrow:
+</p>
+
+<p>
+"Great country, this New Mexico, where you can buy food with sand.
+Good-bye and success to you!"
+</p>
+
+<p>
+The answer was lost in space as the ships parted.
+</p>
+
+<p>
+"And now," said Ned, after lashing the now case of provisions to the
+bridge netting, "we've wasted some more precious time. Do you still
+think we had better lose a night at Camp Eagle? We have all the
+fuel we can carry."
+</p>
+
+<p>
+Alan saw what was in the wind.
+</p>
+
+<p>
+"We have extra provisions, water and gasoline. My own judgment is
+we had better make at once for our starting point."
+</p>
+
+<p>
+"I guess you are right," answered Alan after long thought; "I don't
+know what is to be gained by the trouble of a landing at the camp by
+the lake."
+</p>
+
+<p>
+"Nothing but that hot supper," smiled Ned, "and we'll have to put
+that off a few days, I think."
+</p>
+
+<p>
+"All right," agreed Alan, "set your course and with luck we'll do a
+little treasure hunting before dark."
+</p>
+
+<p>
+This being settled, the prow of the Cibola was pointed a little west
+of northwest, and, dropping to a lower stratum to escape the lively
+eastern breeze at the higher altitude, the boys started at last
+directly for the and arid broken mountains of Northwestern Arizona.
+</p>
+
+<p>
+This region, bordering on the great sand dunes lying beyond the
+Chelly River, was to be the beginning point of their arduous and
+momentous search. From that place to a point nearly one hundred
+miles to the southeast lay the secret fastnesses of mountain, canyon
+and mesa wherein, somewhere, according to the Spanish soldier's
+record, was the secret city of a dead race and the treasure that had
+brought Ned and Alan half way across a continent.
+</p>
+
+<p>
+What such a search meant one glance at the monotonous and unending
+rock easily told. On foot, only the compass could lead a man
+forward in such wilderness of abrupt heights and winding chasms. As
+the boys meant to manage it, the attempt had possibilities, but it
+might mean days of drifting, of watching, of doubling back and forth
+over every possible site. And that was now their task.
+</p>
+
+<p>
+So far as they could, Ned and Alan meant to begin at the extreme
+northern end of this unknown land and, sailing back and forth from
+east to west, cover every foot of exposed ground with their powerful
+glasses.
+</p>
+
+<p>
+Both boys had long since agreed in this conclusion: the "city" meant
+no more than one large structure similar to but on a larger scale
+than those found in the Chaco Canyon at the extreme southern end of
+the Tunit Chas Mountains. This would be indicated now by nothing
+more than rectangular lines of wall stones, probably in piles,
+outlining the shape of the "city" or palace. Prominent among these
+ruins should be the more elevated temple, the object of their
+search. And beneath this should be found the underground "khivas"
+or religious chambers.
+</p>
+
+<p>
+That this "city" was secret or hidden was proof to Ned and Alan and
+Major Honeywell that it would not occupy a prominent place such as
+an exposed plateau or a high level mesa. Only one other location
+was left, the abutting shelf of some canyon. And the young
+navigators had pictured to themselves that, if this should prove to
+be the location, the shelf would be so elevated as not to be visible
+from the front or below and that it would be concealed from above by
+an extended and overhanging cliff.
+</p>
+
+<p>
+"Look for it as you would look for a bird's nest in the cliff,"
+suggested Ned. And that was the plan of search.
+</p>
+
+<p>
+It was nearly three o'clock when the boys had bade farewell to the
+Arrow and about half past five when the Cibola sailed over the
+second ridge of the Tunit Chas. But the course was far to the north
+and there was naturally no sign of the waterfall plateau or Camp
+Eagle. For a time they thought of passing over the camp and
+dropping a message, but this pleasant idea was given up.
+</p>
+
+<p>
+"Although," as Alan expressed it, "one of Elmer's hot suppers and a
+soft bed of balsam boughs to-night wouldn't be bad."
+</p>
+
+<p>
+Ned thought of the four nights of hard floor and agreed, but he
+said:
+</p>
+
+<p>
+"You'll have to forget soft beds if we're ever going to find Cibola.
+We'll come down to-night, though, and make a camp of our own with a
+fire and a pot of coffee, and at daybreak we'll be off."
+</p>
+
+<p>
+The boys had taken a light luncheon just after starting on the
+return trip, and now, soaring over the Tunit Chas again, they began
+to be anxious for night and supper.
+</p>
+
+<p>
+At seven o'clock the peaks and ridges below them had begun to drop
+into foothills and as the great sandy deserts of distant Utah and
+nearer by Arizona came before their eyes the boys decided that it
+was time to anchor for the night. They were sailing over the
+eastern slope of the last low ranges of hills, barren of trees or
+vegetation. The aeroplanes being given the proper depression, the
+Cibola shot earthward and then, the propeller coming to a pause,
+floated gently along above the jumble of rocks. Making fast the
+anchor in a ragged pile of these the boys soon drew the Cibola to
+the ground and lashed her fore and aft to heavy boulders.
+</p>
+
+<p>
+The firm ground felt delicious to the tired boys and they refreshed
+themselves with a brisk race over the open space between the rock
+piles. Then came Alan's camp fire, a hot supper and preparations
+for a good night's rest. There were no pine needles of balsam
+boughs, but fatigue made a fine mattress, and it was not long before
+the tired boys, rolled up in their blankets, were fast asleep on the
+soft sand.
+</p>
+
+<p>
+"I hope," said Ned drowsily as they were dropping off to sleep,
+"that we won't have any Jack Jellups or thieving Utes to-night. My
+nerves need rest."
+</p>
+
+<p>
+Then the boys got eight good hours of health and strength giving
+sleep in the tonic air of the Arizona Mountains.

+<h3>
+CHAPTER XXVI
+</h3>
+
+<h3>
+THE SECRET TUNNEL IN THE MESA
+</h3>
+
+<p>
+At five o'clock Ned and Alan were astir. With regrets that they
+were not at Camp Eagle for a plunge in the cool mountain lake, they
+prepared another hot meal, ate it, and boarded the Cibola.
+</p>
+
+<p>
+The balloon had now been inflated thirty-eight hours and was
+noticeably showing the loss of its gas. While the top of the bag
+was yet round and firm in the heat of the sun the lower sides had
+become a trifle flabby as the cool evening had come on. Up to this
+time all records for balloon flight had been broken a fact due to
+the renewed buoyancy caused each day by the hot, Southwestern Sun.
+And, exploration in and quick ascent from the canyons before them
+would before long call for the use of ballast. The boys agreed that
+the time had arrived to utilize their liquid hydrogen. The
+shrinkage that night had been quite perceptible.
+</p>
+
+<p>
+They regretted that but two-thirds of this remained&mdash;about eleven
+cubic feet. This when reconverted meant nearly twelve thousand
+cubic feet of new gas at their present altitude. As the work of
+converting the gas involved care, preparation for it was made before
+the Cibola was cut loose.
+</p>
+
+<p>
+The reconverter, a reduced inversion of the apparatus used in making
+liquid air, was made ready. When the muffled explosions and the
+heat of the tubes told the boys that the reconverter was working
+perfectly and pumping new and needed gas into the shrunken Cibola's
+long bag, the lashings were loosed and once more the faithful
+dirigible mounted skyward.
+</p>
+
+<p>
+With Major Honeywell's map of the region spread out on the deck of
+the bridge and the binoculars in hand Ned began the long anticipated
+search for the lost city.
+</p>
+
+<p>
+All day the process of turning the liquid hydrogen back into buoyant
+gas went on. And all day the Cibola wound her devious course over
+the peaks and chasms beneath. By night half the hydrogen jars were
+empty and Ned and Alan saw the evening close in on them without a
+sign of the object of their search. When darkness stopped further
+work the balloon was brought to earth and camp made again.
+</p>
+
+<p>
+The following day, as uneventful as the first, gave no indication of
+the secret city. The rest of the liquid hydrogen was transformed
+into gas. The sun seemed to enfold the craft in a fiery embrace.
+When camp was made again that night the Cibola had been afloat
+eighty hours.
+</p>
+
+<p>
+"I think she is good for another forty-eight hours," said Ned that
+night. "If we find nothing in two more days we'll have our choice
+of going out on foot or of quitting in time to pick up Elmer and Bob
+and make a dash to civilization. What do you say?"
+</p>
+
+<p>
+"I don't know," replied Alan, "I'd hate to give up as long as we can
+fly. I think the boys can care for themselves. Let's stick to it.
+We have provisions and there is water in some places."
+</p>
+
+<p>
+"Well," answered Ned, "we'll have two more days time in which to
+decide."
+</p>
+
+<p>
+The next morning the Cibola showed plainly that her gas was rapidly
+escaping. New life was given to the balloon by casting overboard
+some empty hydrogen casks. The fourth day broke hotter than ever.
+In all the wilderness examined by the tired and strained eyes of the
+searchers, not a human being had been seen&mdash;not even a wandering
+Navajo. This day they began the search with renewed vigor, but with
+the same monotonous result&mdash;miles of hopelessly desert rock and sand
+beneath them, with a little vegetation now and then, but so sign of
+Indian remains.
+</p>
+
+<p>
+At noon Ned said:
+</p>
+
+<p>
+"If we were not in a balloon with a compass and sextant I should say
+we were lost. And if Indians ever lived and died hereabouts they
+certainly left so signs of their bones."
+</p>
+
+<p>
+By six O'clock, with the sun gratefully low, Alan expressed
+discouragement.
+</p>
+
+<p>
+"To-morrow at this time," he said, "if we see no indication of the
+old palace or city or whatever it was&mdash;if it ever was&mdash;I think I'll
+vote to try to find Camp Eagle and get out."
+</p>
+
+<p>
+"We'll see to-morrow," answered Ned stoutly.
+</p>
+
+<p>
+That night at dark, a landing was made on the ledge of a point of
+land ending in a rounded cliff pointing south, selected because the
+place was open to the breeze and cool. The Cibola had approached
+the height from the west, and the boys believed that the promontory
+projected from yet higher ground beyond. On those portions of the
+cliff that they could see there was neither shelf nor projection of
+any kind. The walls rose almost like cut stone and were apparently
+about three hundred feet high. As the Cibola was about to descend,
+Alan, who was taking a last survey from the bridge, called Ned's
+attention to the fact that even the far side of the supposed
+promontory was separated from the mountains beyond, and that a chasm
+at least a half mile wide separated the two heights.
+</p>
+
+<p>
+"It's a mesa," replied Ned with renewed enthusiasm, "and it will be
+a good thing to look over it to-morrow. These high and almost
+unapproachable islands of rock were favorite dwelling places for the
+Indians."
+</p>
+
+<p>
+"But a temple up here wouldn't be a secret very long," replied Alan.
+"We've seen this point all afternoon. It's prominent enough."
+</p>
+
+<p>
+"That's so," answered Ned, "but we are here, so let's make a landing
+and eat, and dream over it."
+</p>
+
+<p>
+The balloon had now lost so much gas that a landing was easy, and,
+tired with four days' profitless search and its strain, the young
+aeronauts were soon beyond even dreams.
+</p>
+
+<p>
+It was with no small alarm that the boys saw, when they awoke with
+the first rays of the sun, that the car of the Cibola, which had
+been anchored fore and aft to heaped up rocks during the night, was
+now resting on the ground. Gas, was rapidly escaping. But fortunately
+the aeroplanes and propeller had been left properly in a horizontal
+position and no damage had been done.
+</p>
+
+<p>
+The boys knew that by throwing over enough ballast and stores the
+Cibola could be made good for one more flight, but that probably it
+would be the last. Therefore, the inevitable seemed forced upon
+them. They would fortify themselves with a good breakfast, look
+over the mesa, make one more circling flight and then attempt to
+find Camp Eagle. While Alan made haste to prepare breakfast, Ned
+determined first on an examination of the mesa point by daylight.
+</p>
+
+<p>
+The rock had a top area of perhaps forty or fifty acres. It had a
+rolling surface and was coated with a carpet of dusty sand, except
+in the northwest corner. The northern end of the mesa, Ned could
+see, widened and ended in a sharp rise almost wall-like in form. At
+the western end this wall-like elevation turned the corner and
+extended south a short distance, finally dropping down to the
+general level of the mesa. In this protected comer grew a strange
+grove of gnarled and twisted pines, ill nourished and apparently
+very old. Between this comer of the mesa and the sharper promontory
+whereon the Cibola had come to anchor, was a wide, sandy, barren
+depression.
+</p>
+
+<p>
+The narrow portion of the rocky island where the boys had made camp
+drew in abruptly to make the point that marked the southern end of
+the mesa. Ned turned first toward the point.
+</p>
+
+<p>
+When he had advanced, making his way slightly upward all the time,
+to where the narrow mesa was not over four hundred feet wide, the
+lad was astounded to suddenly discover a deep and narrow fissure or
+chasm. It was dark, with sides as abrupt as the cliffs of the mesa,
+and too wide to jump across. A cold air was already rising from the
+opening into the warmer atmosphere above.
+</p>
+
+<p>
+In his astonishment Ned called to his chum.
+</p>
+
+<p>
+"What surprises me," exclaimed Ned, "is the character of the
+opening. If it extended from cliff to cliff I should say that the
+same freak of nature that made this solitary island of rock also
+split off this end at some time. But it is closed at each end."
+</p>
+
+<p>
+Alan hastened to the end of the fissure, near the side of the mesa.
+</p>
+
+<p>
+"It looks to me," he said, "as if it had extended entirely across at
+some time and the ends walled up later."
+</p>
+
+<p>
+The boys made a closer examination.
+</p>
+
+<p>
+"You're right," said Ned when he discovered that each end of the
+rift had been filled with closely fitted rock, "and human hands did
+it."
+</p>
+
+<p>
+Alan sprang up in excitement.
+</p>
+
+<p>
+"That's the first sign we've had," he exclaimed. "Do you suppose it
+means anything?"
+</p>
+
+<p>
+The edge of the cliff was so abrupt that the boys had to lie down to
+look over in safety.
+</p>
+
+<p>
+"It does," Ned answered. "The reason you can't see that chasm from
+below or from in front is because the face of it is walled up. And
+it is walled so skillfully that you can't detect it from even a
+short distance."
+</p>
+
+<p>
+"That's to hide something," quickly replied Alan, "but I don't see&mdash;"
+</p>
+
+<p>
+Ned was standing on top of the short filled-in portion of the chasm.
+</p>
+
+<p>
+"Look!" he exclaimed, suddenly interrupting his friend. "These
+stones are steps, and, they are worn!"
+</p>
+
+<p><br /><br /><br /></p>
+

+<h3>
+CHAPTER XXVII
+</h3>
+
+<h3>
+THE TURQUOISE TEMPLE DISCOVERED
+</h3>
+
+<p>
+In another moment he had sprung forward and was quickly descending
+into the narrow, dark pit, with Alan close behind. A cave-like
+smell and a rapidly, cooling air greeted them. They were soon in
+almost complete darkness. When the walls had narrowed to but a few
+feet, a thin ribbon of blue sky was all that could be seen above.
+</p>
+
+<p>
+The steps had come to an end. An ascending elevation began just in
+front of them. This they made out by the light of a match, which
+flickered uncertainly in the bad air. Bats dashed against the walls
+and every movement was followed by a cloud of dust.
+</p>
+
+<p>
+"Do you feel anything?" suddenly exclaimed Alan. "Seems to me like
+a current of air on my feet."
+</p>
+
+<p>
+Ned lit another match.
+</p>
+
+<p>
+Before them they again made out an ascending slant such as they had
+come down. But the base of it was hollowed out in the form of a
+small cave. As the light went out both boys stooped to look further
+into this opening.
+</p>
+
+<p>
+"Light!" they exclaimed almost together.
+</p>
+
+<p>
+They were looking through a tunnel made, as they afterward found, in
+the base of the filled-in portion of the chasm. Reptiles, bats and
+dust were forgotten now. Plunging forward on their hands and knees,
+the two boys advanced without difficulty to the distant mouth of the
+tunnel.
+</p>
+
+<p>
+It ended abruptly in the face of the mesa cliff, one hundred feet
+above the valley below. There was not the slightest ledge below it
+and the side of the mesa dropped so precipitately that access to the
+tunnel mouth from without seemed impossible. The possibility of a
+climb to that entrance to reach the mesa above was out of the
+question.
+</p>
+
+<p>
+The boys, panting for breath, lay on the floor of the tunnel with
+their heads just out of the opening.
+</p>
+
+<p>
+"Some one has used this place, but how did they ever get up here?"
+asked Alan.
+</p>
+
+<p>
+"I don't know and I don't care," said Ned with excitement. "But I
+do know that this entrance is concealed. Why, you couldn't even see
+it from below&mdash;it's so small. And it was made that way for a
+purpose. That must mean Cibola. Let's get busy."
+</p>
+
+<p>
+There were one hundred and thirty-five steps to mount, and each was
+about a foot and a half high. When Ned and Alan were on top of the
+mesa again they were out of breath and their clothes were white with
+dust. They were also choked, thirsty and hungry.
+</p>
+
+<p>
+"Eat heartily," laughed Ned, when they began breakfast over again;
+"we are going to have a busy day, I hope."
+</p>
+
+<p>
+"What is your theory?"
+</p>
+
+<p>
+"That our treasure is right here if it is anywhere," exclaimed Ned.
+</p>
+
+<p>
+Alan laughed. "The place is barren as a barn floor," he said; "I
+don't see any very large palace or temple hereabouts."
+</p>
+
+<p>
+"I don't either. That's why I'm going to look for it&mdash;and look
+hard."
+</p>
+
+<p>
+"And our gas slipping away at a lively rate!" interrupted Alan
+again.
+</p>
+
+<p>
+"Let it all go," said Ned. "We know how we can get down within a
+hundred feet of the ground, anyway. That's some consolation."'
+</p>
+
+<p>
+"First we will make a circuit of the north end," continued Ned,
+after breakfast, "and if nothing comes of that&mdash;no unseen hollows or
+new crevices&mdash;we'll try this sandy hollow, even if it is smooth as a
+plain."
+</p>
+
+<p>
+The circuit of a fifty-acre area requires time and it was an hour
+before the boys had traversed the edge of the precipitous cliff. At
+every few yards they examined the face of the mesa for gaps or shelves,
+but there seemed hardly a resting place for a bird.
+</p>
+
+<p>
+Tired and hot, the sun being now high above them, the young
+aeronauts finally reached the north-eastern corner of the mesa
+without finding a sign or suggestion of Indians, or even of animal
+remains.
+</p>
+
+<p>
+Alan had thrown himself on the ground at this point for a rest, when
+with an exclamation Ned darted from his side. As Alan's eyes
+followed him he saw the cause of the exclamation. From where they
+stood&mdash;directly east from the ancient grove&mdash;they could see for the
+first time that the trees stood in a wide double semi-circle, and,
+directly in the center, perhaps fifteen feet in height, arose a
+column of masonry. It was snow white in color and glistened like
+glass.
+</p>
+
+<p>
+There was no question about it.
+</p>
+
+<p>
+The fabled Temple of Turquoise, its deep blue glaze lost in the
+whitening sun of three centuries, stood before them. Almost
+overcome with the emotion of success the two boys stood as if
+transfixed. Then cautiously, as if afraid the wonderful pile might
+dissolve itself into a dream, they moved forward.
+</p>
+
+<p>
+In this protected corner of the mesa where the winds of ages had
+gradually deposited a thin sandy soil, the hand of man had planted
+two almost complete circles of trees. Therein, and generally
+agreeing with the record of the long dead Vasquez, were the plain
+outlines of a stone structure. At places, where the walls crossed,
+and at some of the corners, the masonry yet rose to the height of a
+man. And again, it fell into long irregular piles of jumbled
+blocks. Sifted sand filled each corner and crevice.
+</p>
+
+<p>
+In the center of the ruins rose the turquoise column. From this,
+and in a line with the true east to where the boys stood, extended
+an open approach. Almost reverently Ned and Alan advanced up this
+walk.
+</p>
+
+<p>
+It was easily seen that the structure had contained a maze of
+rooms&mdash;over three hundred, they afterwards discovered&mdash;and that the
+white column stood in a hollow square.
+</p>
+
+<p>
+"It's white," almost whispered Alan.
+</p>
+
+<p>
+"Yes," answered Ned; "it ought to be blue."
+</p>
+
+<p>
+They were now at the foot of the column. Directly in front stood an
+opening or door. Bordering this was a framework of brick-like
+squares or tiles, black, and ornamented with white figures.
+</p>
+
+<p>
+"Just like pottery," said Alan, noticing the true geometrical design
+and the still cruder outlines of animals.
+</p>
+
+<p>
+"Look," exclaimed Ned, pointing to the top of the door.
+</p>
+
+<p>
+Here, the small tiles were replaced with a large square of black
+tile, in the center of which shone a dull yellow radiating design.
+</p>
+
+<p>
+"A symbol of the sun," explained Alan, "and of gold!" he added
+excitedly.
+</p>
+
+<p>
+"Then it certainly is our secret city," said Ned.
+</p>
+
+<p>
+As he said this he was busy with his knife, digging at the
+glistening white bits with which the column was coated. Finally one
+came off. It fell into his hand and the back of it came into view.
+</p>
+
+<p>
+The two boys broke out in an exclamation of delight. The protected
+portion of the piece was a deep sky blue.
+</p>
+
+<p>
+"The Turquoise Temple!" they both cried together. "Hurrah!"
+</p>
+
+<p>
+When night came again Ned and Alan were almost too excited for rest
+or sleep. Nor did they taste food again until the dust of the ruins
+warned them temporarily to abandon their search. To walk into a
+treasure house that the daring adventurers of two races had
+overlooked for three hundred years was enough to turn the heads of
+any two boys.
+</p>
+
+<p>
+The "Doorway of the Sun" as Alan called it, led into a chamber about
+fifteen feet square. The walls of this were lined with smooth clay
+squares of black tile, undecorated. Eight feet above the floor,
+which was also of clay tile and half buried under sand, rose a
+ceiling of arched stones. There was no opening in this, but steps
+on the outside of the temple and in the rear led to a chamber above,
+in the front of which, and also facing the sun, was another opening
+about two feet from the floor. In front of this window was a stone
+bench or altar. The meaning of it the boys did not know. This room
+was barren of either decoration or utensil and it was half full of
+the debris of what had apparently been another arched stone roof.
+Only the front or eastern side of the structure was coated with the
+precious turquoise; the other sides of the column were of plain,
+fairly well fitted, mortarless stone blocks.

+<h3>
+CHAPTER XXVIII
+</h3>
+
+<h3>
+THE COLLAPSE OF THE CIBOLA
+</h3>
+
+<p>
+An opening in the paved court in the rear of the Temple, half filled
+with drifted sand, led into a "khiva" or secret religious council
+chamber beneath. Herein the young adventurers discovered their
+wonderland and the reward for all their labors.
+</p>
+
+<p>
+Hastily returning to the balloon, they procured candles and
+improvised scoops out of the sides of the tin emergency ration case
+obtained from the Arrow. Major Honeywell had warned the boys that
+the floors of all closed chambers of this sort were covered with the
+accumulated dust of ages.
+</p>
+
+<p>
+The first examination of the "khiva" resulted in disappointment.
+The immediate impression that the boys received was one of cave-like
+barrenness. In the half-light only a gray monotony met the eye.
+Yet under this ghostlike pall, forms soon began to appear. In the
+center of the chamber stood what was apparently an altar. In spite
+of its burden of dust an elevation could be seen about eight inches
+high and seven feet in diameter, on which was a boxlike structure
+about three feet square and four feet high. On top of this was a
+dust-covered figure. Beyond, in the deepest gloom, the mouths of
+four radiating tunnels leading still further into the ground could
+be seen. The roof was supported by irregular round columns,
+apparently of wood, arranged in two circles.
+</p>
+
+<p>
+Before beginning an exploration of the chamber the boys decided to
+ascertain the depth of the dust covering the floor, into which they
+had already sunk over their shoe tops. This was stifling work, for
+the soft powder ran back as fast as it was dug away. A half hour at
+least was consumed in reaching the bard surface beneath. The
+coating of dust was nearly three feet deep.
+</p>
+
+<p>
+As Ned climbed out of the little excavation Alan held the candle
+down. To the astonishment of the boys a beautiful blue sheen met
+their gaze.
+</p>
+
+<p>
+"Turquoise flooring!" shouted Ned.
+</p>
+
+<p>
+It was true. The entire "khiva," so far as the boys subsequently
+uncovered its floor, was a crude mosaic of the most perfect
+turquoise, the pieces, varying in size, being laid in a lime-like
+cement.
+</p>
+
+<p>
+A general survey of the room and its connecting tunnels showed that
+each radiating arm led, with about twenty feet of passageway, into a
+smaller room. In each of these rooms were nine column placed in a
+rectangle. The main chamber was circular in form, forty-eight feet
+in diameter, and the smaller apartments were twenty-four feet
+square.
+</p>
+
+<p>
+Ned while at work examining the floor, suddenly ceased and rushed to
+one of the columns.
+</p>
+
+<p>
+"You remember," he exclaimed, "the Spaniard said these columns were
+of gold and silver."
+</p>
+
+<p>
+But in this the ancient record was wrong. The inner six supports
+were painted a faded yellow and the second row, twelve in number,
+was colored red, as the boys discovered later when they brushed and
+cleaned some of them. Around each of the inner columns, however,
+there were two metal bands about two inches wide and thirty inches
+apart. The lower ones were six feet from the floor. They were of
+heavy gold with loops or hooks extending from each side, as if
+festoons or connecting bands had once extended from pillar to
+pillar.
+</p>
+
+<p>
+"Not a bad substitute!" exclaimed Ned.
+</p>
+
+<p>
+The second line of twelve columns had similar rings of silver, as
+the boys discovered in good time. The movable contents of the room
+were not easily examined, as each object on the floor was buried
+under a mound of heavy, suffocating dust. Bats had made the place
+an undisturbed refuge, and the repulsive flutter of these creatures
+was disconcerting.
+</p>
+
+<p>
+A preliminary examination of the four lateral passages and the rooms
+at their far end showed that these were probably store rooms,
+excepting the one on the east side. Here, on shelves, fixed on
+columns or posts similar to the colored supports in the principal
+chamber, were eight oblong forms. Even the dust and refuse could
+not disguise the nature of these&mdash;they were unmistakably mummies,
+the embalmed bodies of either chiefs or priests. At the head and
+foot of each were various dust covered receptacles and utensils.
+</p>
+
+<p>
+The afternoon was too short for the boys to accomplish the removal
+of anything.
+</p>
+
+<p>
+"I feel like a grave robber," panted Alan, soberly, as the two boys
+clambered out into the fresh air, finding, to their surprise, that
+it was already night.
+</p>
+
+<p>
+"Well, I don't," said Ned. "These things are so old that they seem
+to belong to Time itself. I feel more like a gold miner who has at
+last struck a rich vein&mdash;and it's our vein."
+</p>
+
+<p>
+But, as so often happens, ill luck came close on good fortune. The
+first glance of the young aeronauts at the camp and the Cibola was
+enough to chill their new happiness. The big gas bag had settled so
+low that it half concealed the car, which was resting flat on the
+ground. The buoyancy of the air ship was gone. Without more gas
+the Cibola could not make another flight. It was a severe blow to
+Ned and Alan; but they met the issue squarely.
+</p>
+
+<p>
+"There is no use in worrying," said Ned, finally, when they realized
+the exact situation, "and we've got to make the best of it.
+Besides," he said, laughing, "we are not ready to go."
+</p>
+
+<p>
+"That's right," replied Alan, thinking of the yet unexamined
+contents of the Treasure Temple, "and when we are ready I guess
+we'll be no worse off than Bob and Elmer. I suppose we can manage
+the one hundred foot descent some way."
+</p>
+
+<p>
+Ned pointed to the hundreds of yards of net cordage.
+</p>
+
+<p>
+"Right," exclaimed Alan, "that'll be easy&mdash;a rope ladder."
+</p>
+
+<p>
+It was almost dark and the boys were covered with the penetrating
+grime of the long undisturbed "khiva." A meager wash up and supper
+and rest were in order. But Ned said:
+</p>
+
+<p>
+"By morning the Cibola will be in collapse. It is a valuable
+machine, and it ought not be left out here on this point unprotected
+from the seasons. We shall probably never see it again, but while
+we can move it let's tow it over in front of the temple and put the
+bag and engine and instruments in the protected room."
+</p>
+
+<p>
+It was not a difficult task. With no great effort the car was half
+carried and half dragged down the slope and then to the clearing in
+the pine grove where the boys soon made a new camp. To complete
+their work the big bag of the balloon was untied from the car and
+drawn, half inflated, into the pathway leading to the temple door.
+Then, with no small regret, the boys opened the escape valve, and in
+a few minutes the collapsed Cibola was stretched like the cast off
+skin of a snake along the sandy pathway, ready to be rolled up and
+compactly stored away.

+<h3>
+CHAPTER XXIX
+</h3>
+
+<h3>
+THE GOLDEN EAGLE OF THE AZTECS
+</h3>
+
+<p>
+In the morning the boys went at their task with renewed vigor.
+Inventory was first taken of the stores and provisions. There was
+enough food for about six days, if used with care. Of water there
+was a supply apparently for a little longer period. But the choking
+dust of the "khiva" made bathing almost a necessity, and, used in
+this way, even sparingly, the supply would not last over two days.
+</p>
+
+<p>
+"No more baths until we go down into the valley," ordered Ned.
+"Cleanliness would be a comfort, but we'll have to be uncomfortable."
+</p>
+
+<p>
+Permanent camp was made in the cabin of the dirigible. In arranging
+this all the machinery, the engine, the blower, the dynamo, the
+reconverter and the aeroplanes, the rudder and the propeller were
+unmounted, and the smaller articles made ready for storing in the
+temple entrance. There were four casks of gasoline left unused. As
+these were being carried to the temple Ned suddenly exclaimed:
+</p>
+
+<p>
+"Why not rig up the engine and dynamo and use an electric light down
+in our cave of Mystery."
+</p>
+
+<p>
+"Good," answered Alan, "and while we are at it, why not hook up the
+balloonet blower with the engine and get fresh air?"
+</p>
+
+<p>
+The stowing away of the machinery, the packing of the gas bag and
+the setting up of the engine and dynamo and blower afforded plenty
+of work until noon; and then, while the trusty little engine was
+pumping volumes of good sweet air into the hot, almost suffocating
+chamber below ground, the boys had luncheon.
+</p>
+
+<p>
+Then began the real exhumation of the long buried articles in the
+secret religious chamber of the almost forgotten race. As
+revelation succeeded revelation in the next two days the paralyzing
+wonder that first came to Ned and Alan was succeeded by the dullness
+of fatigue. At intervals of not more than an hour they came above
+ground for fresh air. The absence of water soon converted them into
+bronze-like human statues. They could feel that their lungs were
+becoming clogged with the almost impalpable dust. But they
+persevered. The prize was too rich to be abandoned because of mere
+physical discomfort.
+</p>
+
+<p>
+By means of the wired drag rope the powerful incandescent light was
+carried to all the chambers. And one after another, as the blower
+gave the boys air and helped sweep away the clouds of dust, the
+remains which had lain buried for over three centuries were
+uncovered and brought above ground.
+</p>
+
+<p>
+Of the pottery itself, vases, jars, and religious ceremonial
+utensils, perfect in shape and displaying ornamentation that would
+have delighted Major Honeywell, the excavators could take little
+note. After removing the twelve gold hoops or bands from the
+supporting columns and twenty similar silver rings from the second
+row of pillars, the boys penetrated the elevation in the center of
+the "khiva."
+</p>
+
+<p>
+As the end of the blower pipe was directed against this square
+column, the sediment of centuries disappeared. Then the brilliantly
+penetrating glare of the reflected electric light fell on the
+elevation and both boys burst out in an exclamation of amazement.
+</p>
+
+<p>
+</p>
+
+<p>
+On what had been a ceremonial dais stood the treasure of the secret
+city of Cibola&mdash;an image of the sacred Golden Eagle of the Aztecs.
+The revered bird of the Aztecs stood upright, its extended head
+peering east. The body of this aboriginal work of art, crude in
+form, was of massive silver. And to it were attached overlapping
+plates of gold in the similitude of feathers. The unfolded wings
+were also of gold. The head, beak and talons were of gold, and the
+eyes were two polished bits of quartz. The idol, for such no doubt
+it was, stood forty inches in height and weighed about three hundred
+pounds.
+</p>
+
+<p>
+The base on which the precious eagle stood was completely covered
+with the deepest blue turquoise. At its foot and covering the dais
+were the crumbled traces of many articles of cloth, feathers, bits
+of wood and pottery, and the like, all, no doubt, fragments of
+priestly utensils of worship. The most ornate and best preserved of
+these was a large flat bowl covered on the inside with skillfully
+cut mother-of-pearl. This was still iridescently beautiful, and the
+more striking because its milk white exterior was unmarked by
+decoration.
+</p>
+
+<p>
+Each mummy, when hauled into the open air and examined, gave more
+positive proof of the riches that had been collected in this sacred
+retreat. The funeral bowls placed at the feet of the bodies varied
+in form and material. Some of these were of plain black and white
+pottery, others were coated with gold, silver, or mother-of-pearl.
+The bowls apparently had once contained food. In all there were
+two golden bowls, four of silver, one of pearl and one of pottery.
+</p>
+
+<p>
+Each mummy was wound with as much care as was ever bestowed on the
+Egyptian royal dead. The woven wrappings were coated with pitch and
+beneath them were colored cotton cloths, affording proof of a high
+civilization. The richest treasures of the dead were the
+breastplates and necklaces found on each. These astounded the young
+investigators.
+</p>
+
+<p>
+These plates and beads had been strung on deer sinews, which, not
+having been protected by pitch, were now only lines of dust. But,
+lying on the breast of each there was invariably a "body scraper,"
+(as Major Honeywell afterwards termed them) of gold, silver or
+mother-of-pearl. Mother-of-pearl discs were the commonest neck
+decoration. Of these the boys discovered four.
+</p>
+
+<p>
+On three of the bodies were pierced pearl bead necklaces. On the
+most elaborately wrapped figure, that of a head priest or high
+chief, came the crowning discovery. This was a necklace of pierced
+amethysts. And on the breast of this figure was a flat plate of
+gold with sixteen radiating points, each of these terminating in a
+large luminous unpierced and polished amethyst.
+</p>
+
+<p>
+About the waist of this shriveled figure were the remains of a
+jeweled belt. The foundation or back of this had dissolved into
+dust, but careful unwrapping of the cerements revealed the priceless
+ornamentation. This decoration was of alternating squares of
+mother-of-pearl, in each of which glistened a perfect amethyst, and
+of matchless turquoise squares set with great pearls.
+</p>
+
+<p><br /><br /><br /></p>

+<p><a id="chap30"></a></p>
+<h3>
+CHAPTER XXX
+</h3>
+
+<h3>
+A QUARTER OF A TON OF TREASURE
+</h3>
+
+<p>
+It was impossible for the boys even to venture an estimate on the
+value of the immense mine of turquoise, although they realized that
+the increasing scarcity of the jewel made the beautiful and unique
+specimens everywhere about them worth a great deal of money. Nor
+had they any idea of the value of the mother-of-pearl bowls, nor of
+the hundreds of beautiful and unique ceremonial and funeral urns and
+vases. Least of all, could they put even an approximate price on
+the amethyst and pearl necklaces. Even their most sanguine hopes of
+discovering the hidden city of Cibola had not led the adventurers to
+investigate the current prices of precious stones.
+</p>
+
+<p>
+Knowing, however, what the prices of gold and silver were, they
+could form some estimate of the worth of this part of the treasure.
+</p>
+
+<p>
+By comparison with the known weights of certain articles in the car
+the two boys made the following list of metal pieces discovered:
+</p>
+
+<pre>
+ GOLD POUNDS
+
+ Twelve bands. Weight each 2 lbs. 1 oz. 26
+ Two bowls. Weight each 6 lbs 12
+ Two "body-scrapers." Weight each 9 oz 1 1/2
+ Wings, head and talons of Sacred Eagle 82
+ Breastplate 3
+ Radiating sun over entrance 12
+
+ Total, 136 1/2, or 1,638 ounces.
+
+ SILVER POUNDS
+
+ Twenty-four bands. Weight each 1 lb. 8 oz 40
+ Four bowls. Weight each 5 lbs 20
+ Four "body-scrapers." Weight 10 oz.. 3 1/3
+ Body of Sacred Eagle. Weight 218
+ Ninety-six miscellaneous rings, bands,
+ anklets and wristlets, many set with
+ mother-of-pearl and turquoise 16 1/3
+
+ Total, 297 2/3, or 3,580 ounces.
+</pre>
+
+<p><br /></p>
+
+<p>
+The market value of these precious metals was easily computed. The
+silver at sixty cents an ounce was worth $2,148. The more valuable
+gold, at twenty dollars an ounce, was worth $32,760. Together, the
+484 pounds were worth $34,908.
+</p>
+
+<p>
+"And one-third of that," said Ned with a smile&mdash;almost discernible
+beneath his dust&mdash;begrimed face, "is nearly $12,000. And that is
+$6,000 for each of us."
+</p>
+
+<p>
+"But how about the amethysts and pearls?" said Alan.
+</p>
+
+<p>
+"I suppose," answered Ned, "that they are worth a great deal more,
+but I don't know. I should think that those that have no holes in
+them would be very valuable."
+</p>
+
+<p>
+All this figuring was intensely interesting, but the boys, as the
+revelation progressed, knew that they were now facing a new problem.
+They could not possibly carry that gold and silver, to say nothing
+of even a portion of the exquisite mother-of-pearl bowls or the
+finest samples of the turquoise. When, in the end, nearly a quarter
+of a ton of the metal treasure alone lay in a heap in the corner of
+the temple vestibule they could come to but one conclusion.
+</p>
+
+<p>
+This portion of the treasure would have to be removed at another
+time.
+</p>
+
+<p>
+"It has lain here undisturbed for over three hundred years," said
+Ned hopefully, though sadly, "and we'll have to take a chance that
+it can be left a while longer."
+</p>
+
+<p>
+Sorrowfully enough Alan agreed. It was to be no easy work getting
+out of the wilderness, and food must be carried. That might be more
+precious to them than gold before they saw a railroad again. The
+boys agreed to take at noon the next day the exact latitude and
+longitude of the mesa. The latitude, on one slip of paper, was to
+be carried by one boy and the longitude, on another piece, was to be
+in the possession of the other. This was a precaution against
+accidental revelation of the treasure mesa.
+</p>
+
+<p>
+The set jewels were removed. There were two hundred and ninety-four
+pierced pearls and ninety-eight pierced amethysts. Among the whole
+gems, eighteen magnificent pearls were extracted from the jeweled
+belt. Eighteen unpierced amethysts were also taken from the
+alternating turquoise squares of the belt and sixteen magnificent
+amethysts from the gold breastplate.
+</p>
+
+<p>
+It was then that the sewing kit supplied by Alan's sister Mary came
+into service. A small piece of aluminum waterproof silk cabin
+covering was converted into two flat bags and in these the stones,
+equally divided, were enclosed and concealed under the clothing and
+beneath the right arm of each lad. In addition, each boy took half
+of the mother-of-pearl and turquoise belt plates as the finest
+specimens of each material.
+</p>
+
+<p>
+"And to show that there is gold too," suggested Alan, "we might as
+well take along, these gold 'scrapers,' which won't bother us much,"
+So these two pieces were strung on cords and suspended about the
+necks of the young treasure seekers.
+</p>
+
+<p>
+"And to-morrow," exclaimed Ned joyfully when all this was done,
+"we'll get down from here and get a bath."
+</p>
+
+<p>
+"Amen," added Alan earnestly.
+</p>
+
+<p>
+Until it was twelve o'clock, the time to take their observation, the
+boys spent the next morning in last preparations and making
+everything shipshape. The framework of the car was left intact, but
+weighted by stones to prevent injury by the wind. Everything
+movable was stored in the entrance room of the temple, including
+three and one-half cans of gasoline. The engine was oiled and
+covered with blankets. Underneath the smoothly folded balloon, in
+the folds of which dry sand had been liberally sprinkled to prevent
+possible adhesions of the varnish, lay nearly thirty-five thousand
+dollars' worth of curiously wrought gold and silver. This was first
+completely covered with sand.
+</p>
+
+<p>
+The two provision packs for the retreat to civilization had been
+carefully arranged. How long the journey might take they could not
+estimate. They had decided to their way east, in hope of falling in
+with Elmer and Bob, and this meant the crossing of at least two
+mountain ranges and thirty miles of barren foothills to Mount
+Wilson. Then, if they turned south, they would traverse eighty-five
+miles of sandy plain in which water was infrequent.
+</p>
+
+<p>
+Their own provisions were exhausted. What they now depended on was
+the emergency case secured from the Arrow. This supply was intended
+to be enough for two men for two weeks.
+</p>
+
+<p>
+"It certainly ought not take us that long,"' complained Alan. "Why
+not leave half the supply and take a little gold?"
+</p>
+
+<p>
+But Ned was obdurate. He explained that they might fall in with the
+other boys, and that if they did Elmer and Bob might be wholly out
+of supplies.
+</p>
+
+<p>
+"We can come back if we get out in good shape," explained Ned, "and
+if we don't get out what'll be the use of a back load of gold?"
+</p>
+
+<p>
+That settled it. The food packs were made up of the following
+supplies: Flour, 12 lbs; corn meal, 5 lbs; beans, 5 lbs; bacon, 7 1/2
+lbs; rice, 5 lbs; oatmeal, 2 lbs; baking powder, 1/2 lb; coffee, I
+lb; tea, 1/2 lb; sugar, 5 lbs; lard, 2 1/2 lbs; salt, 1/2 lb; pepper,
+1/8 lb. Each provision pack weighed twenty-one pounds. In addition
+there was an aluminum frying pan, a coffee pot and two aluminum
+plates. A water canteen, a blanket, a revolver and belt of
+ammunition and a knife apiece completed the equipment. Alan carried
+in addition the "snake bite" case, the compass and small hatchet,
+and Ned the money belt containing over five hundred dollars in gold.
+</p>
+
+<p>
+The sealed glass tubes of matches were divided between the two boys
+and then, as it was noon, the sextant that Ned had been so careful
+to bring with them was used for the first and last time. The
+observation made and noted, and the record of it divided as planned,
+Ned and Alan were ready to begin their attempt to make their way out
+of the rock-bound wilderness. With provisions, water, blanket and
+arms each lad was carrying about thirty-five pounds.
+</p>
+
+<p>
+"Would you still like a few pounds of Aztec treasure?" laughed Ned
+as they stood with packs adjusted.
+</p>
+
+<p>
+"I should say not," retorted Alan; "I'm satisfied."
+</p>
+
+<p>
+The method of lowering themselves from the hole in the face of the
+cliff to the ground, one hundred feet beneath, had been worked out
+in detail and the apparatus made in the evenings by the light of
+their camp fire. And early that morning Alan had carried the long
+rope ladder down the chasm and to the mouth of the tunnel. Now, in
+addition to their packs, the two boys carried between them a section
+of one of the pine trees, about six feet long.
+</p>
+
+<p>
+As they stood, ready to leave, Ned raised his cap.
+</p>
+
+<p>
+"Good bye, old Cibola," he said with moisture in his eyes, "until we
+meet again, if ever."
+</p>
+
+<p>
+"If ever?" added Alan quickly with as much gaiety as he could
+summon. "You don't think we'll ever let anyone else lift that
+little pile?" and he pointed to the well filled entrance room of the
+temple.
+</p>
+
+<p>
+"No," answered Ned, soberly, "if we have as good luck on the land as
+we had in the air."
+</p>
+
+<p>
+Ned and Alan meant to reach the earth by means of a rope ladder.
+This they had constructed from the stout Italian hemp suspension
+cords of the Cibola. These ropes, each thirty feet in length, were
+knotted and then doubled to insure strength. For the last
+twenty-five feet at the bottom the landing ladder of the balloon was
+used. The rungs, two feet apart, were of pine from a felled tree,
+and were thirty-eight in number.
+</p>
+
+<p>
+For anchorage, the six-foot length of tree was dragged to the mouth
+of the tunnel and, five feet from the opening, wedged between the
+floor and roof of the tunnel, slightly inclined forward. The strain
+on the bottom would thus only fix the supporting section more firmly
+in place. From the bottom of the pine shaft a loop of four of the
+suspension cords reached just out of the tunnel opening. To this
+loop the top rang of the ladder was tied, with a separate
+hundred-foot length of cord. After the ladder had been made firm
+with a running slip knot the hundred-foot length of cord was dropped
+to the ground.
+</p>
+
+<p>
+This arrangement had been provided in order that the rope ladder
+might be removed after the descent. By a jerk of the cord the slip
+knot would be loosened and the ladder, released, would fall of its
+own weight. Another length of rope had been prepared, this one
+somewhat over a hundred feet long and also doubled for strength.
+This was for the lowering of the packs and other articles by one of
+the boys after the other had descended. To insure its free running
+and to prevent its wearing through on the edge of the cliff, a six
+inch section of the pine tree had been prepared, flattened on one
+side and having a wide smooth groove in the top. This, attached to
+a short length of rope, which was made fast with the ladder loop to
+the upright shaft in the tunnel, was fixed on the verge of the
+opening.
+</p>
+
+<p>
+Finally everything had been arranged and made fast. Each of the two
+boys insisted that he should go down first. To solve the dispute,
+they cast lots and the risk of testing the rope fell to Ned.
+Slipping off his shoes and socks, which he hung about his neck, he
+sprang to the ladder. Alan hung over the edge and watched him with
+apprehension, but Ned, feeling his way carefully, was soon on the
+ground.
+</p>
+
+<p>
+His shout was the signal to begin the work of lowering the packs.
+And down they came, one after another; provisions, revolvers,
+blankets, water bottles, and even the money belt, for Ned had made
+himself as light as possible for his descent.
+</p>
+
+<p>
+At last it was Alan's turn. The last load had descended, the
+lowering line had been released, drawn up and stowed away. The slip
+knot was examined anew and then Alan followed Ned down the slender,
+fragile swaying rope ladder. When he had reached the ground by
+Ned's side and the strain was over, the boys shook hands jubilantly.
+</p>
+
+<p>
+"&mdash;And now," shouted Ned with a laugh, "last chance! If you want to
+go back for a new load say so before it is too late."
+</p>
+
+<p>
+Alan, exhausted with the climb, shook his head.
+</p>
+
+<p>
+"Then stand from under," cried Ned.
+</p>
+
+<p>
+As he jerked the slip knot cord the boys sprang aside and the long
+ladder, wriggling, crashed at their feet.
+</p>
+
+<p>
+The only means of reaching the towering elevation had been removed
+and the only visible sign of their brief occupancy of the secret
+mesa had been destroyed.

+<h3>
+CHAPTER XXXI
+</h3>
+
+<h3>
+AN ADVENTURE WITH THE NAVAJOS
+</h3>
+
+<p>
+Three days later, Ned Napier and Alan Hope, worn and almost
+exhausted with the steady climb and descent of countless rocky
+heights, made their camp for the night at the foot of a rugged
+slope. Their shoes were torn so that a protection of rags was
+necessary. The hot and pitiless sun had seemingly dried up their
+boyish spirits. Silent with fatigue, having plodded steadily
+forward since sunrise, they threw themselves on the sand.
+</p>
+
+<p>
+The young adventurers were headed straight for the east. And still
+the last range of mountains was beyond them. Led by the compass,
+they held to their course, sometimes passing miles out of their path
+to avoid some inaccessible mesa, but more often scaling ragged and
+tiresome heights.
+</p>
+
+<p>
+Eating had now become a matter of form and necessity. There was no
+longer the keen joy in making camp. During the three days the boys
+had seen no living object except birds, rabbits, many deer and two
+bears, all of which they had left unmolested in their eagerness to
+press forward. But at noon on this day Alan, having occasion to
+glance backwards, was positive that he saw a human head. Whether
+white man or Indian he could not determine. The incident gave the
+lads no little, concern, but as no further sign of a human being was
+seen that day they finally forgot the matter.
+</p>
+
+<p>
+That night, after making tea and taking a little more pains than
+usual with their supper in an effort to revive their spirits as well
+as their tired bodies, Ned and Alan spread their blankets at the
+edge of a pine grove. Almost before it was dark they were both
+sound asleep.
+</p>
+
+<p>
+Some hours later Alan awoke with the instant consciousness of an
+unusual sound. Motionless and straining his ears, he heard deep
+breathing just behind him. A new moon was just sinking below the
+buttes on the far side of the little valley in which they had
+stopped for rest, but under the pines the shadows were deep. He
+knew that danger was near and he did not move. In another moment he
+felt a soft hand on his waist, as swift and as silent as a snake,
+and he knew that the hand was extracting his revolver.
+</p>
+
+<p>
+Then, from his half-opened eyes, he saw a figure crouching over his
+chum just opposite. Some one no doubt was also removing Ned's
+weapon. Then there was the pressure of stealthy footsteps on the
+pine needles and Alan moved his head until he could see two
+indistinct forms moving from the shadows of the timber across the
+open space to the dying embers of their little fire. There he could
+easily discern five or six figures. He was about to put his hand on
+Ned's face to awaken him gently when he saw the entire group coming
+directly toward their sleeping place. Their movements now revealed
+plainly that they were Indians.
+</p>
+
+<p>
+With cold beads of perspiration covering his body Alan again
+pretended sleep. It was now apparent that they had been followed,
+and, no doubt, by Navajos. Perhaps this was the end of their
+toilsome retreat. With visions of death presenting themselves, he
+wondered again whether he ought to arouse Ned. Then he realized the
+futility of such action. As the moccasined feet drew near Alan
+could read death in each approaching sound. But at the edge of the
+trees there was another pause, and then he knew that the Indians had
+scattered.
+</p>
+
+<p>
+Straining every muscle in an effort to breathe naturally, like one
+asleep, the boy counted the seconds while he waited for the clutch
+of a savage hand. And as the moment passed and the attack did not
+come he tried to speculate on what the strangers were doing. A
+guttural half exclamation soon allowed him a quick breath of
+temporary relief. The Indians were only after their supplies.
+</p>
+
+<p>
+The savages had found the half-concealed packs of the two boys.
+Alan knew this by the location of the sounds that now came to him,
+and then, as the prowlers withdrew again into the open and the faint
+moonlight, it could be seen that they were bearing all the
+belongings of the two lads. For perhaps ten minutes Alan lay
+without moving and watched the Indians. He could make out that they
+were hastily looking over the packs and dividing what yet remained
+among themselves. Then ponies were led to the place of the camp
+fire and the members of the band quickly threw themselves on their
+animals and disappeared into the night.
+</p>
+
+<p>
+Almost paralyzed with the knowledge of what this meant Alan now
+softly put his hand on Ned's face:
+</p>
+
+<p>
+"Are you awake?" came instantly from Ned.
+</p>
+
+<p>
+"Are you?" retorted Alan in surprise.
+</p>
+
+<p>
+"Yes," whispered Ned, "I saw it all. But I didn't move, because I
+was afraid of arousing you."
+</p>
+
+<p>
+"Here, too," exclaimed Alan. "Did you feel them take your
+revolver?"
+</p>
+
+<p>
+Ned's band flew to his belt.
+</p>
+
+<p>
+"Is yours gone too? I saw them when they came up from the fire.
+But you did right to keep still. If we had moved I expect we'd have
+had our throats cut."
+</p>
+
+<p>
+"That was one of them I saw to-day," added Alan, "and I guess we're
+lucky to be alive."
+</p>
+
+<p>
+"Yes," added Ned rising to his feet, "we are. They are satisfied, I
+suppose, to let us starve."
+</p>
+
+<p>
+The prospect was a trying one. If the range behind them was the one
+they hoped it was, there was only one more valley between its summit
+and the outer ridge of the Tunit Chas. If they could reach this
+ridge they believed they might see Mount Wilson's peak. But even
+that meant another thirty miles to the scene of the attack on Buck's
+camp on the banks of the Chusco. And from that place it was
+eighty-five miles to a railroad and help!
+</p>
+
+<p>
+The boys sat in the edge of the pines as the new moon disappeared,
+leaving them in utter darkness, and tried desperately to encourage
+each other. Both had the grit to set themselves stoutly to the
+apparently hopeless task. Without food or firearms and possibly
+without water, they knew they would find the task gigantic. But
+nothing was to be gained by waiting for starvation and death in the
+wilderness, and their decision was to do what they could, to try the
+almost impossible, and if they failed to fail with their faces
+toward the east.
+</p>
+
+<p>
+"Why not start now?" urged Alan. "Let's use what strength we have."
+</p>
+
+<p>
+But Ned showed him the folly of this.
+</p>
+
+<p>
+"A night's rest will enable us to make better time to-morrow. And
+besides, we can't make headway when we can't follow the compass."
+</p>
+
+<p>
+Retiring a little further into the woods the boys composed
+themselves again and before long were once more fast asleep.

+<h3>
+CHAPTER XXXII
+</h3>
+
+<h3>
+ALAN SUCCUMBS TO EXHAUSTION
+</h3>
+
+<p>
+The boys were up at dawn. Not an article had the marauders left but
+the two water canteens which had fortunately been left hanging from
+the low branches of a pine. It was useless to look for more&mdash;there
+was nothing more to be found.
+</p>
+
+<p>
+"Anyway," laughed Ned, "it leaves us in light marching order and we
+can make better time. I'm glad we had a good supper."
+</p>
+
+<p>
+As no breakfast was in sight the two boys filled the water bottles
+at the creek in the valley, and at five o'clock, taking their
+bearings due east, Ned and Alan struck upwards through the pine
+woods. It was a not unpleasant climb while the boys were fresh, but
+as the slope grew more precipitous the work began to tell. At one
+o'clock the crest was reached.
+</p>
+
+<p>
+"How would you like a piece of broiled bacon, some pancakes and a
+cup of coffee, Ned?" asked Alan as they paused to rest.
+</p>
+
+<p>
+"In the middle of the day and on the top of a mountain I always
+prefer plain water," laughed Ned in reply. "Here's to you!"
+</p>
+
+<p>
+With a big drink from the lukewarm canteens the boys did not pause
+long.
+</p>
+
+<p>
+"To-night," continued Ned, "we ought to sleep high up in the
+foothills over there."
+</p>
+
+<p>
+With that inspiration the sore-footed and jaded lads made good time
+going down the slope. Then another rivulet was encountered, in
+which they bathed and by which they rested a spell. Alan would have
+been glad to pass the night here, but Ned urged him on, and as night
+fell again the hungry, exhausted boys found themselves far up on the
+new slope. Then they slept again, restlessly and on the rocky
+ground, for they had abandoned their blankets.
+</p>
+
+<p>
+The boys did not wait for daylight. In the half dawn they were
+afoot.
+</p>
+
+<p>
+"Take another hitch in your belt, chum, and don't think of the
+Placida." laughed Ned. "We'll make it all right, somehow."
+</p>
+
+<p>
+Stiff in limb, their feet twitching with the pain of blisters, Ned
+and Alan toiled slowly through the last of the pines and out into
+the rocky higher slopes of the range. It was like climbing an
+upright wall, Alan said, but the pain of going on was less than the
+despair of giving up. A little after six o'clock Ned, ahead, pulled
+himself breathless to the highest point.
+</p>
+
+<p>
+Alan stopped a little below and waited in anxiety. Before he could
+ask whether it was the last ridge, Ned's voice broke out into a
+shout.
+</p>
+
+<p>
+"Come on, old man, we're all right. There's old Wilson, the
+grandest mountain peak in the world. Hurrah for Mount Wilson!"
+</p>
+
+<p>
+But there was no echo to his exclamation. Poor Alan, succumbing to
+pain and exhaustion, had sunk insensible to the ground. In another
+moment Ned was at his chum's side. Forcing some water between
+Alan's lips and bathing his face with some more of the precious
+liquid, Ned soon brought him back to consciousness. Alan sprang up
+in chagrin, and with tears in his eyes insisted that he had only
+stumbled and fallen. But Ned knew the truth. His friend's bright
+eyes and feverish skin told that his condition was grave.
+</p>
+
+<p>
+The unseen tears came to Ned's eyes, for it was at least thirty
+miles to more water and the plains. And should they even reach the
+Chusco, he could see only death in the desert.
+</p>
+
+<p>
+"You'll feel better in the cool of the woods down there," said Ned
+gently, "and maybe we can kill a rabbit. Hurrah, come on, Alan!
+Brace up. It's all down hill, now. Here's for the woods and
+broiled rabbit!"
+</p>
+
+<p>
+In a new spurt of life another start was made and the two chums set
+out down the slope. In one of Ned's hands was a rock. It was to be
+the death warrant of any small animal, and his eyes were busy
+examining each sheltered rocky nook and bush. Suddenly a feverish
+hand caught his.
+</p>
+
+<p>
+"Look," whispered Alan.
+</p>
+
+<p>
+Ned's eyes followed his chum's gaze.
+</p>
+
+<p>
+It was a spiral of thin smoke in the trees below.
+</p>
+
+<p>
+With a shout, Ned sprang forward. Then he turned. Alan was
+standing still. Ned's heart grew cold:
+</p>
+
+<p>
+"See the smoke," Alan was repeating, "see the nice smoke. Maybe
+it's a house on fire."
+</p>
+
+<p>
+His friend was delirious. Ned flew to his side once more and again
+his touch revived the exhausted boy. Almost five days of wandering
+and the exhausting toil on the mesa had proved too much for the more
+delicate Alan, and Ned realized with sickening horror that the
+situation was critical.
+</p>
+
+<p>
+"I'm all right, Ned," answered Alan when his chum was once more with
+him; "just a little lightheaded. But that's all."
+</p>
+
+<p>
+What was to be done? The smoke might be that of a forest fire. And
+it might mean Indians. But even an enemy is welcome when starvation
+and death confronts one. Almost at the end of his own resources,
+the determined Ned forced himself into a last effort. He used no
+words of persuasion, for Alan allowed Ned to take his hand, and
+thus, silently and slowly, the two moved forward again. Perhaps
+another half mile was made between rocks and down gullies and then
+Alan exclaimed pitifully:
+</p>
+
+<p>
+"It's no use, Ned, I can't, I can't. My feet." Burying his
+fevered face in his hands, the boy wept, partly in pain and partly
+because he knew that he was holding back his chum.
+</p>
+
+<p>
+At such periods Ned Napier was at his best. With kind words he
+sought to encourage his friend. He used the little water left to
+bathe Alan's face, and the last of his shirt in binding anew his
+friend's bleeding feet. He tried to joke and speculated on the
+possibilities of the smoke beyond them, but it was without avail.
+Poor Alan could not rise again. The fever of exhaustion was on him
+and with a last appeal to Ned to leave him the boy threw himself on
+the ground and fainted away.
+</p>
+
+<p>
+There was no doubt now as to what was to be done. Unless he could
+bring help to his friend in a short time Ned knew it would mean
+death. And that meant death for both, for young Napier would never
+abandon his friend. Like a drunken man Ned turned and stumbled
+forward.
+</p>
+

+<h3>
+CHAPTER XXXIII
+</h3>
+
+<h3>
+A FORLORN DASH FOR HELP
+</h3>
+
+<p>
+Am hour later Alan Hope, carried by the faithful Elmer Grissom and
+the jovial Bob Russell, was laid gently on a blanket by the fire
+whose smoke had attracted the attention of the ragged, worn
+wanderers. Not until the sun had set did the exhausted lad open his
+eyes again. But water and food had been forced through his lips and
+when reason came back strength was not far behind.
+</p>
+
+<p>
+Ned sat by his chum's side all day, bathing his face and making him
+as comfortable as possible; from Elmer's medicine packet. A few
+mouthfuls of food had sufficed Ned. But that night, when Alan came
+again to his senses, the four boys held a thanksgiving about a
+cheerful fire and ate together. But it was no banquet.
+</p>
+
+<p>
+What had happened was soon repeated to the weak but happy Alan.
+Elmer and Bob had waited and watched for ten days, using their
+stores sparingly and ready always for the return of Ned and Alan.
+Two days they had seen the Cibola a speck in the sky far to the
+west, and had watched it from the little waterfall on the edge of
+the plateau. Then it disappeared and they never saw it again. This
+was three days after the boys departed from Camp Eagle.
+</p>
+
+<p>
+Husbanding their provisions as well as they could, they at last
+decided to start on their return to the outside world.
+</p>
+
+<p>
+This was two days before. The tent and the heavier articles were
+hidden in a cache. Their food had been reduced to a meager
+quantity. They had two pounds of bacon, six pounds of flour, two
+ounces of tea and a little over a pound of beans. In addition they
+had a half dozen bouillon tablets, a little salt, pepper and sugar,
+and a complete and unopened medicine packet in which were quinine,
+adhesive plaster, cotton, bandages, morphine, and other needed and
+compact drugs. With this light pack each boy had a rifle and a
+revolver, a few cooking utensils and a blanket.
+</p>
+
+<p>
+Elmer had his own water bottle, and Bob improvised two out of the
+empty baking powder can and a lard pail.
+</p>
+
+<p>
+Thus equipped, Camp Eagle was abandoned, and led by their compass
+Elmer and Bob had set out bravely for Mount Wilson and the Chusco.
+But it was with no small regret that they made their way up the long
+slope behind them and then across the valley beyond. But, fresh and
+strong of limb, they pushed forward and with Mount Wilson as a
+landmark made camp on the second night in the timber on the slope of
+the outer range.
+</p>
+
+<p>
+Never wholly despairing of meeting Ned and Alan again, the two boys
+were frugal both of their strength and their stores. The food they
+carried would have been sufficient for a healthy man for perhaps a
+week. They could not count on reaching civilization again within
+that time, even with good luck. That meant half rations at the
+best. But if accidents came and delay even half rations would be
+cut down. So, that night, in camp, there was no feasting. A little
+tea, and a cake of dough apiece made their supper; and then they
+slept.
+</p>
+
+<p>
+In the morning as they were about to breakfast and be off again Bob
+caught sight of a deer. A little jerked venison would not come
+amiss, he thought, and as the ammunition was plentiful he darted
+through the woods in pursuit. The fact that Bob was a poor hunter
+probably saved Alan's life. He was gone an hour and a half and when
+he returned it was after seven o'clock.
+</p>
+
+<p>
+The two boys had just extinguished their fire and were about to
+shoulder their packs when a well-known but strained call arrested
+them.
+</p>
+
+<p>
+"Camp ahoy?"
+</p>
+
+<p>
+It was their leader, Ned Napier, his cheeks sunken, and his body
+swaying from weakness, but cheery as of old, advancing slowly
+through the trees.
+</p>
+
+<p>
+Food and a night's rest restored Ned's strength. "And now, my
+friends," said he in the morning, "these bandages and a little food
+and good companionship have worked wonders. We are all ourselves
+again. But we can't stay here, pleasant&mdash;as it is. Alan ought not
+to travel for another day and then he ought to have some husky
+attendant. Bob, you are nominated for that job. Elmer and I will
+take a few pinches of tea, the soup tablets, one revolver and a
+rifle and&mdash;"
+</p>
+
+<p>
+"And what?" exclaimed Alan, suspicious of Ned's suggestion.
+</p>
+
+<p>
+"And," continued Ned, "We'll just dash on ahead and bring you some
+help."
+</p>
+
+<p>
+"No, siree," shouted Alan. "Do you think get back to Clarkeville,
+one hundred and fifteen miles or more, on six soup tablets? And for
+me? If you think you ought to go, all right. But you'll take half
+of the food."
+</p>
+
+<p>
+"Or more," interrupted Bob, "give us a little flour and salt and
+some matches. I reckon I can get a deer before night."
+</p>
+
+<p>
+But Ned convinced them in the end that he was right. He argued that
+each mile he and Elmer made in advance was nearer help. Alan must
+advance slowly.
+</p>
+
+<p>
+"All you've got to do," he explained to Bob and Alan, "is to reach
+the Chusco, where Elmer camped, and take care of yourselves for
+seven or eight days. And we'll be there to help you, unless
+something happens. You won't have much to eat but you'll have water
+and you have ammunition."
+</p>
+
+<p>
+And at seven o'clock that morning they parted. Just before the
+farewells Alan called Ned to one side and said:
+</p>
+
+<p>
+"Hadn't you better take my bag?" indicating the jewel case under his
+arm.
+</p>
+
+<p>
+"Why?" answered Ned.
+</p>
+
+<p>
+"Well, you know we may never see each other again."
+</p>
+
+<p>
+Ned took his chum's hand.
+</p>
+
+<p>
+"Alan," he said, "we were not born to lose ourselves in the woods,
+much less to die there. We'll meet again all right. Don't you have
+any fears on that point. But if we shouldn't, I won't care for
+amethysts or pearls. If I don't see you again it'll be because I'm
+beyond the need of those things."
+</p>
+
+<p>
+There were handshakes and cheering, good wishes, and the relief
+section was off.
+</p>
+
+<p>
+"Elmer," said Alan, after the two had been trailing through the
+trees Indian fashion some time, "it is daylight at four o'clock and
+dark at seven&mdash;that's fifteen hours. Can you walk two miles an
+hour?"
+</p>
+
+<p>
+"Sho'ly," smiled Elmer, showing his white teeth.
+</p>
+
+<p>
+"Well, that's thirty miles a day. If we could do that for four days
+we'd be in Clarkeville!"
+</p>
+
+<p>
+"Clarkeville in fo' days it am den," echoed Elmer, "or bust."
+</p>
+
+<p>
+"We've got six soup tablets. If we dine on one at ten o'clock in
+the morning and one at seven o'clock in the evening we'll have
+regular meals for three days."
+</p>
+
+<p>
+"And de las' day we won't need none, we'll be in such a hurry,"
+added the colored boy, happy again in Ned's company.
+</p>
+
+<p>
+That was the spirit in which the expedition started. Late that
+afternoon they emerged from the timber and were on the sandy
+foothills where progress was faster. Ned's feet bothered him and he
+was in constant pain, but the adhesive plaster and cotton had been
+of the greatest help. There was no pause. The first day's schedule
+he was determined to make and at about eight o'clock the relief
+expedition gave a shout. The Chusco lay before them.
+</p>
+
+<p>
+A little fire, some tea and bouillon&mdash;made in the pan after the tea
+was consumed&mdash;and the two boys found a bed on the soft sand with no
+covering but the deep Mexican sky. At dawn they were up and away
+after a bath in the muddy river. Elmer was now the guide and he
+readily picked up Buck's old wagon trail. Sharp at ten o'clock a
+halt was made for breakfast, bouillon now without tea. Ned, his
+face a little more sunken and his legs a little more unsteady than
+the day before, was sitting on the ground resting his burning feet,
+when Elmer suddenly touched him on the shoulder, set the soup pan
+quickly on the sand and drew his revolver.
+</p>
+
+<p>
+Far down the trail a horseman was approaching. Behind him in the
+distance followed a wagon. What did this mean?
+</p>
+
+<p>
+"Well, whoever it is, we'll have the soup," said Ned.
+</p>
+
+<p>
+This consumed, Ned and his friend started forward.

+"If it's good luck we'll meet it sooner this way," said Ned, "if
+it's bad we'll know the worst quicker."
+</p>
+
+<p>
+But it was good luck. The rider soon galloped up and swung his wide
+hat in the air. It was Curt Bradley, the mayor of Clarkeville.

+<h3>
+THE RESCUE
+</h3>
+
+<p>
+They told Ned afterwards that he keeled over in the sand and fainted
+dead away, but he always insisted that he didn't faint, that he knew
+everything that was going on. Yet he did not hear a word of the
+long story told by Elmer. When he roused himself he was lying in
+the shade of the big freight wagon and a couple of cowboys were
+getting breakfast ready.
+</p>
+
+<p>
+Then Mayor Bradley explained his presence in that mysterious way in
+which bad news always travels friendly Indians had sent him word of
+the attack on Buck's outfit and of the death of the veteran
+plainsman. This news had just reached Clarkeville and Mayor Bradley
+had at once set out to find the body if possible, and assist those
+who escaped.
+</p>
+
+<p>
+Of course all speed was made toward the foothills and that evening
+Alan and Bob, the former only a shadow of the lively youngster who
+had left Clarkeville but two weeks before, were found and rescued.
+That night there was a new camp on the Chusco and meat and hot
+bread. The only shadow to dim the happiness of the rescued boys was
+the recollection of the murdered Buck.
+</p>
+
+<p>
+The return to Clarkeville was made by easy stages in four days, and
+even Alan was nearly his old self when that town was reached. One
+night's rest in real beds, with fresh linen from the baggage they
+had left behind them, and baths, removed the traces of privation and
+suffering. There was little more to detain Ned and Alan.
+</p>
+
+<p>
+A telegram was dispatched to Major Honeywell at Kansas City, where
+the boys and their patrons had agreed to meet. Then Ned's tool
+chest was forwarded by freight to Chicago. In company with Mayor
+Bradley Ned and Alan visited Mrs. Bourke, Buck's widow. Retaining
+enough to cover the costs of transportation to Kansas City he gave
+the widow what remained of his funds, nearly five hundred dollars,
+and all the heavy stores remaining in the corral.
+</p>
+
+<p>
+At midnight of that day four wide-awake and alert boys, neatly clad
+in summer suits, boarded the local train bound east for Albuquerque.
+The last hand they shook was that of Mayor Bradley.
+</p>
+
+<p>
+"Mr. Mayor," said Ned as he parted from his friend, "I'm sorry I
+can't tell you why we were here, or what we were doing. But you
+were our friend and we'll never forget you. Some day I'm going to
+show you how highly we regard you. And some day I hope I'll be able
+to tell you what our mission was."
+</p>
+
+<p>
+Three days later the quartette of boys sprang from the Limited in
+the Union depot at Kansas City. The parting had come. None of the
+boys knew what that meant until the last moment.
+</p>
+
+<p>
+"'Ned," said Bob Russell, once again in the field of his profession,
+"I've had many a strange assignment in my work and I expect to have
+many another, but I'll never have one like this. I've got the story
+of my life, but I haven't got yours. If the time ever comes when I
+can write it, when you are free to tell it, just remember your best
+friend, Bob Russell, reporter, Kansas City Comet."
+</p>
+
+<p>
+"Bob," answered Ned wringing his hand, "you have missed a good
+story. I'm sorry. It wasn't because you were not a good reporter.
+It was just our good luck. But if things work out the way I hope,
+I'm going to give you something better than a good story."
+</p>
+
+<p>
+"And," broke in Alan, "just want to say this: if chance ever throws
+adventures my way again I hope that the companions I share it with
+will always include Bob Russell."
+</p>
+
+<p>
+The details of how Ned and Alan, just one day late, kept their
+engagement with major Honeywell and Senor' Oje in the Coates House,
+and of the almost unbelievable report they made and the rich
+evidence of its genuineness that they submitted do not really belong
+in an account of the flight of the Cibola. Two things were done at
+once, however. A handsome gold watch was purchased and sent to
+Mayor Bradley with the compliments of Ned and Alan, and Senor Oje
+forwarded an additional check for a thousand dollars to Buck's
+widow.
+</p>
+
+<p>
+The report on the value of the stones carried from the treasure
+temple by the two boys was such that Senor Oje gave them his check
+for $25,000. Out of this each boy contributed part of his share
+toward a sum sufficient to give Elmer a business education. Finally
+the two boys bought a draft for a thousand dollars, payable to
+Robert Russell. With it went this note: "Please accept this as some
+slight compensation for the story you did not get."
+</p>
+
+<p>
+But in good time Bob Russell did get his story. For, otherwise,
+this narrative would never have been written.
+</p>
+
+<p>
+How it came about that Bob got his story; how the treasure left in
+the Turquoise Temple was finally lifted; how the young aeronauts in
+doing it battled successfully with a maelstrom in the clouds, were
+driven far out over the Pacific, cast away on a derelict and finally
+made an escape with their "sneering idol" by aeroplane into the
+wilds of Mexico, is a later and more remarkable chapter in the
+adventures of Ned Napier and Alan Hope, to be told in "The Air-Ship
+Boys Adrift, or Saved by an Aeroplane."

+phrase "Project Gutenberg" is associated) is accessed, displayed,
+performed, viewed, copied or distributed:
+
+ This eBook is for the use of anyone anywhere in the United States and

+ are located before using this ebook.
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is
+derived from texts not protected by U.S. copyright law (does not
+contain a notice indicating that it is posted with permission of the
+copyright holder), the work can be copied and distributed to anyone in

+ License. You must require such a user to return or destroy all
+ copies of the works possessed in a physical medium and discontinue

+trademark. Contact the Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+works not protected by U.S. copyright law in creating the Project
+Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
+electronic works, and the medium on which they may be stored, may
+contain "Defects," such as, but not limited to, incomplete, inaccurate
+or corrupt data, transcription errors, a copyright or other
+intellectual property infringement, a defective or damaged disk or
+other medium, a computer virus, or computer codes that damage or
+cannot be read by your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project

+or entity providing it to you may choose to give you a second
+opportunity to receive the work electronically in lieu of a refund. If
+the second copy is also defective, you may demand a refund in writing
+without further opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS', WITH NO

+including legal fees, that arise directly or indirectly from any of
+the following which you do or cause to occur: (a) distribution of this
+or any Project Gutenberg-tm work, (b) alteration, modification, or
+additions or deletions to any Project Gutenberg-tm work, and (c) any
+Defect you cause.
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of
+computers including obsolete, old, middle-aged and new computers. It
+exists because of the efforts of hundreds of volunteers and donations
+from people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future
+generations. To learn more about the Project Gutenberg Literary
+Archive Foundation and how your efforts and donations can help, see
+Sections 3 and 4 and the Foundation information page at
+www.gutenberg.org
+
+
+
+Section 3. Information about the Project Gutenberg Literary Archive Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Contributions to the Project Gutenberg Literary
+Archive Foundation are tax deductible to the full extent permitted by
+U.S. federal laws and your state's laws.

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

+
+By H. L. Sayler

+
+
+CHAPTER I
+
+THE DEPARTURE OF THE OVERLAND LIMITED
+
+
+The Overland Limited, aglow with lights, stood in the Dearborn
+Street station in Chicago waiting for eight o'clock and the last of
+its fortunate passengers. Near the entrance gates, through which
+perspiring men and women were hurrying, stood the rear cars of the
+train. Within these could be seen joyous passengers locating
+themselves and arranging bags and parcels.
+
+In fifteen minutes the long journey of Ned Napier and his chum Alan
+Hope to the far southwest was to begin.
+
+At the other end of the big shed, where the cars of the long train
+seemed to fade almost out of sight, four persons were anxiously
+awaiting the approach of the hour of departure. One of these, the
+conductor of the train, consulted his watch, as he had done several
+times already, holding it close within the glow of his green-shaded
+lantern.
+
+"It's getting pretty close to time, Major Honeywell," he said with
+some concern. "You're sure he'll be here?"
+
+The man addressed, who stood leaning lightly on a cane and whose
+soft dark hat and clothes indicated his military calling, showed
+similar concern, but replied confidently:
+
+"We have nearly fifteen minutes. Young Napier has a reputation for
+never failing. I'm sure he'll be here in time."
+
+"Here's the telegram," interrupted young Alan Hope, as he drew a
+yellow sheet from his pocket. "It is from Youngstown, Ohio, and
+says Ned's train is on time. He left Washington yesterday and if
+everything is all right he reached the Union Depot a half hour ago.
+He'll be here."
+
+"Well, you know we can't wait, much as I'd like to," replied the
+conductor. "You'd better have everything ready."
+
+"She's dat, sah," interrupted the fourth person of the group, a
+young negro, who, as he spoke, placed his hand on the side door of
+the car, and moved it on its easy running bearings.
+
+"You see, there isn't much time left," continued the sympathetic
+train official. "We're coupling up." And he nodded toward the
+gloom beyond the train shed out of which the big compound locomotive
+was already emerging. The military man with the cane became more
+apprehensive.
+
+"What shall we do if Ned fails to get here?" he said suddenly after
+peering down the long platform toward the busy end of the station.
+
+"Oh, we didn't go into this to fail," cheerily responded the youth
+by his side. "If we 'fall down' it won't be on a simple thing like
+this. He'll be here. It won't take us but three minutes to
+transfer the stuff when it gets here. Never fear. I'll just take
+another look in the car to make sure."
+
+As he did so the colored boy exclaimed:
+
+"It's all right. Here's de screws as he done tole us to git and
+here's de screw-driver outen de box as he done writ us to have ready
+and dar's de door all ready fur to fly open."
+
+To prove it the lad gave the wide door in the side of the car a
+shove, and as it ran back on its track a portion of the inside of
+the car was exposed. It was a peculiar car and worth description,
+for in it, next to the big engine and ahead of all the other cars of
+the almost endless train, Ned Napier, his friend Alan Hope, and
+their servant, Elmer Grissom, were to be the sole passengers on a
+most mysterious and, as it proved, most eventful journey. In
+railroad parlance the car was what is known as a "club" car. Half
+of the interior was bare and unfinished, like the compartment in
+which, on special and limited trains, baggage is carried. This part
+of the car, now exposed to view, was dimly lighted with one
+incandescent bulb. In the half-light it could be seen that the
+space was almost wholly filled with tanks, boxes, casks, crates and
+bundles, all systematically braced to prevent jarring or smashing.
+It was plainly not the luggage of ordinary travelers. Except for a
+narrow passageway in the center of the car and a space about five
+square next the open door, every inch, to the very ventilators of
+the car, was crowded with bound or crated, numbered and tagged
+packages. In the open space next the door Alan Hope now appeared.
+
+"Coming yet?" he asked with apparent confidence as he peered
+outside.
+
+The colored boy Elmer shook his head.
+
+Just then the conductor returned and again his watch.
+
+"Eight minutes," he said; "time's getting along and I've got to go
+back and see about my train. I don't want to make you nervous, but
+do you want us to take this car if fails to get here with the
+stuff?"
+
+"I suppose there's no need," replied the military man, beginning to
+show irritation. "But there's eight minutes yet."
+
+"I know," replied the conductor, "but after we are coupled up and it
+is time to leave we can't stop to cut this car out. We've got to
+have five minutes for that. At five minutes of eight you'll have to
+decide whether it is go or stay. I'm sorry--but you'll have to
+decide in a minute or two."
+
+"Decide it now," interrupted Alan from the open car door. "We're
+going and he'll be here."
+
+The Major appeared to be in doubt as to the wisdom of this, but
+before he could say anything Alan continued:
+
+"Couple up whenever you want to, Mr. Conductor, we'll be ready," and
+he sprang out of the car, his face set with determination.
+
+By that time the throbbing engine had silently moved up next the car
+and two grimy depot men with smoky torches had swung off the
+footboard to make the connections.
+
+"Got to know," repeated the sympathetic conductor. "Only five
+minutes." He looked at the Major for the final word.
+
+The latter peered down the long almost vacant platform. There was
+no one in sight but the late arrivals being helped aboard the cars
+in the far end of the station. Then he gave another look of appeal
+at his own watch as if in doubt what to say. To send a special car
+half way across the continent was no inexpensive project. And to
+send it without the person or the precious material that it was
+intended seemed not only a waste of money but foolish. Although the
+anxious man had both confidence and nerve it could be seen that he
+was in a quandary.
+
+"Five minutes," exclaimed the railway official. "Does she go or
+stay?"
+
+Before the man could answer, Alan faced him and with a hand on the
+Major's arm exclaimed:
+
+"Ned will be here, he can't fail; tell him we're going."
+
+The Major smiled. "That's it," he exclaimed suddenly. "Take her
+along. It's up to us to take care of ourselves."
+
+"Good," said the conductor, "I hope he'll make it."
+
+With a signal to couple on the engine he hurried away for a final
+inspection of his train.
+
+For a moment the three persons left behind stood in silence. There
+was a hiss of the engine as it pushed the connecting blocks together
+and then those waiting so anxiously could hear the jar of connecting
+valves as the brake hose were snapped. Confident as Alan was, it
+gave him a sinking feeling. Then, as the swish of tests sounded and
+the gnome-like figures of the depot men crawled from under the car,
+the Major looked again at his watch in despair.
+
+"Four minutes--"
+
+Before he could say more Alan caught sight of a movement among those
+gathered around the last car at the far end of the depot.
+
+"There he is!" he shouted and darted forward.
+
+"He sho'ly is," exclaimed Elmer, his white teeth showing, "and Yar's
+de screw driver and yar's de screws all ready."
+
+A slowly moving truck had carefully turned the end of the waiting
+train and, drawn by two baggage-room employees, was making its way
+along the platform. By its side walked a boy--a lad of about
+seventeen. One of his hands rested on the truck and his eyes were
+carefully fixed on the load it bore. This was a black, iron-bound
+case about four feet long, three feet deep and perhaps a yard in
+height. On each side in red letters were the words:
+
+"Explosive; no fire." Beneath this ominous legend were two large
+iron handles.
+
+When the men drawing the truck quickened their pace the boy spoke to
+them sharply and they fell again into a steady walk. For the
+curious onlookers through whom the strange little caravan passed the
+lad by the side of the truck seemed to have no concern. A traveling
+cap was pushed back from his young face and his keen and alert eyes
+and the tone of his voice indicated a quality that goes with those
+born to command.
+
+"Hello, Ned," came a ringing greeting from Alan as he ran forward.
+"They were afraid you wouldn't get here. But I knew you would.
+It's only a minute or two. Hurry."
+
+"Four," said the new arrival cheerfully and confidently.
+
+He gave his left hand to Alan and a better welcome in a cheery word
+of greeting, but his right hand did not leave the truck. Nor did
+his eyes leave it except for a moment.
+
+"And the Major?" asked the new arrival as the truck rumbled on.
+
+"Waiting to bid us good-bye."
+
+"Everything aboard and shipshape?"
+
+"Everything but this," and Alan glanced at the black case on the
+truck.
+
+"I've carried it a thousand miles like a baby," laughed Ned. "Rode
+with it all the way in the express car."
+
+"Then you didn't sleep last night?"
+
+Ned laughed. "It was too interesting," he answered, "and I can
+sleep to-night. But I'm glad it's here with no one killed and not a
+drop spilled."
+
+Advancing leaning heavily on his cane, the military man had hurried
+forward, his face radiant.
+
+"Welcome, my boy, and congratulations. But for goodness' sake
+hurry," he began hastily.
+
+Ned smiled again. "I think we had better not hurry this," and he
+pointed to the truck load. "That's the reason I'm late. I walked
+the horses from the Union Depot. You see we can't afford to spill
+our supplies. It was too hard to make and cost too much."
+
+In another moment the truck was abreast of the open car door.
+
+"Back her up," exclaimed Ned giving a hand himself to the tongue of
+the truck. Then, as the top of the truck came up flush with the car
+door and floor he sprang lightly on the truck and motioned the men
+to do likewise. For a moment they hesitated, but being reassured,
+Ned and Alan and the truck men lined up on either side of the big
+case. Slowly and carefully, with a brawny truck man on each side to
+help the less stoutly muscled lads, the case slid forward and with a
+"yeo-ho" or two from Ned it was soon in the car. Without a pause it
+was pushed at once into a space outlined on the floor.
+
+"And about two minutes to spare,"' cried the Major from the platform
+jubilantly and thankfully.
+
+"Not quite," laughed Ned, "but it'll be a half a minute and that's
+as good as an hour. The screws, Elmer."
+
+The colored boy, who had been busy keeping out of the way, sprang
+forward to perform his part of the apparently ticklish job. It was
+then seen that each bottom corner of the mysterious box had an iron
+flange. In the center of' each of these was a small hole.
+
+"Major," called out Ned as the truck men climbed out of the car,
+"these men were very obliging and careful."
+
+The Major understood him, and as he began searching his pockets for
+a bill Ned quickly inserted four screws in the waiting holes and
+with a few sharp turns of the screw driver made the case hard and
+fast to the floor of the car. Almost as quickly he threw the door
+into place and bolted it, and then with Alan hurried out for a last
+word to the friend who was so much interested in his success.
+
+"Was I right?" he exclaimed. "Half a minute?"
+
+"To the dot," enthusiastically answered the Major. "Now, boys,
+good-bye. Everything in that car is exactly as you planned and
+asked. From now on it is subject to your orders alone. What mine
+are you know. God bless you both and good luck to you!"
+
+As the boys took his hand Ned handed him a letter. "I'm sorry I
+couldn't have seen my mother again, but please send her this. I
+wrote it to-day on the train."
+
+Far down the line of cars came the words, "all aboard," and Elmer,
+cap in hand, sprang onto the steps.
+
+"Good-bye," exclaimed Alan, "and thank you for the great chance
+you're giving us."
+
+"Good-bye," said Ned, "if we fail in our work it won't be your
+fault, Major."
+
+And then, as the train began to move, the boys stepped aboard, off
+at last, after six weeks preparation, in search of the lost Cibola
+and the treasure of the Turquoise Temple.
+
+
+
+
+CHAPTER II
+
+NED'S MEETING WITH MAJOR BALDWIN HONEYWELL
+
+
+Six weeks before Ned Napier and Alan Hope had set out on this trip
+Ned had been the surprised recipient of a mysterious note. In this
+message, written on the stationery of the Annex Hotel, he was urged
+to call on the writer the next morning at ten o'clock. With his
+mother's approval he had kept the engagement. The events which
+followed will explain how Ned came to take his momentous journey to
+the far southwest.
+
+Promptly on the hour Ned presented himself at the office desk. A
+clerk with a handful of letters gave him a half glance and turned
+away.
+
+"I say," began Ned in a voice that made the clerk turn quickly, "I
+want some information."
+
+The man stepped forward, leaned over the counter far enough to get a
+full view of his questioner, and answered:
+
+"All right, sonny. What can I do for you?"
+
+"You can tell me if Major Baldwin Honeywell is staying here."
+
+"Friend of Major Baldwin's?" asked the clerk, his smile broadening.
+
+"If Major Honeywell is stopping here I suppose he is paying well for
+his entertainment," replied Ned after a moment's pause.
+
+"Sure," answered the facetious clerk, "regular rates."
+
+"Perhaps that ought to include civil attention to those he has
+business with. I have an appointment with him at ten o'clock. I
+wish you would see at once that he knows I am here."
+
+The clerk's smile was not quite so broad now but he was still
+amused.
+
+"What name shall I give, son?" He was about to repeat the "sonny"
+that had grated a little on Ned's sense of the proprieties but he
+stopped short--and added: "Have you a card, Mr.--?"
+
+"I have no card and I don't call myself 'Mr.'," answered Ned, "but
+you can say that Ned Napier is here and will be glad to see Major
+Honeywell whenever it is convenient."
+
+At the mention of "Ned Napier" the clerk's airiness disappeared. A
+certain respect seemed to take its place. Then he leaned forward
+and said a good deal more politely: "You are not the Ned Napier?"
+
+"I never heard of any other one of that name," answered the boy.
+"But I think we are losing time. Please say I'm here."
+
+A moment later a page announced that Major Honeywell, in suite 8 A,
+desired Mr. Napier to be shown up at once. Reaching the apartment
+the page knocked and there was a quick "Come in."
+
+Hat in hand, and with all the manliness and dignity his seventeen
+years afforded, Ned stepped into the room. At a table a man had
+just risen as if from work on some papers. As the man turned to
+come forward and his eyes fell upon the lad he paused as if
+surprised. Ned Napier was neither large nor small for his age. But
+his circumstances had been such, financially, that his attire was
+plain and perhaps old fashioned--much of it the handiwork of his
+frugal and fond mother; and the absence of smart and up-to-date
+ideas in clothes and shoes made him look, perhaps, even younger than
+his years. Other lads of his acquaintance--those in his classes in
+high school--aped their elders. Ned's time and interests were too
+much given up to his boyish ambition to permit this.
+
+Ned saw a man of about sixty years, with snow-white moustache,
+dressed in blue. The man had every appearance of being both a
+soldier and an officer. His face was tanned as if by much exposure
+to the sun, but the line of white at the top of his forehead, where
+his hat gave protection, suggested that the color was both recent
+and transitory. Major Honeywell's hair, which was yet dark and only
+slightly streaked with gray, was too long to suggest present active
+service, as Ned at once concluded. His face, too, had something of
+the student in it, and this effect was increased by a pair of large
+gold spectacles with double lenses. The man's contracted eyes gave
+the youth the uncomfortable feeling of being microscopically
+examined, and Ned was for a moment ill at ease. The manner of the
+scrutiny was that of a scholar who had before him a strange new
+specimen. Ned, still with hat in hand, felt more like a dead bug
+than a very live boy. Then the white-mustached man smiled, took
+off his heavy-lensed glasses, and stepped forward with his hand
+extended.
+
+"I am Major Honeywell," he began in a low voice, "formerly of the
+regular army and later detailed on ethnological work for the
+Government. You are--"
+
+"Ned Napier," responded his youthful caller.
+
+"You must take no offense if I am a little surprised," exclaimed
+Major Honeywell; "I had supposed you would be older. Perhaps your
+surprise came first on receiving my note?"
+
+"It did," replied Ned; "I was surprised and so was my mother. But
+she thought I ought to come, although we could not imagine what you
+wanted."
+
+Major Honeywell smiled and motioned Ned to a chair with a
+graciousness that made the lad more comfortable. It had taken but a
+passing glance to reveal to the boy that he was in the presence of
+no ordinary man. The articles scattered about the room, which
+apparently were part of his host's traveling outfit, confirmed this.
+Of three leather cases or trunks in front of the mantel and within
+Ned's view, one was open. On the extended top of this, still partly
+covered with the folds of a light Indian blanket, were several flat
+and dull plates or dishes of Indian design, more or less broken and
+chipped. From the case came a pungent aromatic smell such as Ned
+had noticed in the "Early American" room of the museum. He was not
+quite sure what "ethno" meant, but he made a guess that it related
+to old Indian things, and this theory he confirmed to himself when
+he noticed on the table that Major Honeywell had just left another
+piece of pottery and by its side a large reading or magnifying
+glass.
+
+"A collector," thought Ned, more puzzled than ever.
+
+"I thank you for coming," said Major Honeywell finally. "It was
+good of you to do so. But I had supposed you were older--at least a
+young man," and he smiled again as if in some doubt.
+
+"Perhaps," replied Ned with just a shadow of resentment in his
+voice, "if you will tell me why you sent for me I can help you in
+making up your mind as to whether you were wrong in doing so. I'm
+seventeen."
+
+Major Honeywell arose, took off his glasses again and walked to
+where Ned was sitting.
+
+"I hope you'll not take offense, my boy. But my business with you
+is most important. It is possibly the most important thing that has
+ever come to me. Fate, or chance more properly, of course, seems to
+have brought us together. If what I have in mind and have partly
+hoped could be brought about, is brought about, you will have no
+reason to regret my sending for you. We must be sure of ourselves.
+So far we know almost nothing about each other. Since our
+acquaintance may mean a great deal to us let us be sure of
+ourselves. Therefore, you will pardon me if I ask you if you are
+the Ned Napier?"
+
+Ned laughed good-naturedly.
+
+"That's what the clerk down stairs asked me few moments ago--if I
+were the Ned Napier. Well, I never heard of any other Ned Napier.
+But boys don't carry credentials, you know, Major Honeywell. I'll
+take your word for it that you are Major Baldwin Honeywell, formerly
+of the United States Army, and now of the--what do you call
+it--ethno--?"
+
+"Ethnological survey," laughed the Major. "Then, since we know each
+other, I want to congratulate you, my young friend, on being one of
+the brightest, nerviest, and most promising young men of America.
+I've read about you and that's why I sent for you."
+
+Ned could only conclude one thing and it made him blush. "You mean
+my dirigible balloon experience last summer?" he asked with growing
+embarrassment.
+
+"I do," replied Major Honeywell with what Ned thought was wholly
+unnecessary warmth and enthusiasm, "and I want to shake the hand and
+congratulate the youngest, most daring and most promising balloon
+navigator in the world."
+
+
+
+
+CHAPTER III
+
+THE RELATION OF MIGUEL VASQUEZ
+
+
+It may be well to recount how such a young lad as Ned had become so
+famous.
+
+Ned's father had been a consulting engineer with a fondness for
+aeronautics. When Mr. Napier died, a year before Ned's meeting with
+the Major, it was discovered that he was making in his little shop a
+small dirigible balloon to be used at an amusement park. Mr.
+Napier's death was sudden. Manufacturer's bills for the balloon bag
+and engine came due and Ned, young as he was, knew that he must pay
+them. Putting on all the dignity that his sixteen years would
+permit he called on the manager of the amusement park.
+
+"I hear your father is dead," said the manager. "I suppose we have
+lost the twenty-five per cent we advanced on the air ship."
+
+"Why do you suppose that?"
+
+"Because he had complete charge of the work and we have no one to
+take his place."
+
+"I mean to do that myself," said Ned.
+
+The manager smiled and shook his head. "No doubt you would try--you
+look it--but we don't care to experiment."
+
+"But you want the air ship, don't you? You've advertised it."
+
+"Yes, it was ordered--through your father. Since he is dead and
+cannot contribute his services, our agreement is void."
+
+"Very well," replied Ned. "Good day."
+
+"Look here," interrupted the manager, "what do you mean to do?"
+
+"I'm going out to sell an air ship."
+
+"You mean our air ship?"
+
+"You said the contract is void."
+
+The manager laughed again, but not as jovially.
+
+"You ought to get on," he exclaimed.
+
+"I've got to get on, and I'm going to do it by being on the square."
+
+"I guess you're right. What's your proposition?"
+
+"Since you've thrown up the contract I'm going to sell the balloon
+at a profit. The price is now $3,000. And I want a contract as
+operator for six weeks at $100 per week."
+
+The manager stared at Ned and then exclaimed. "I'll do it. You are
+the very youngster we want."
+
+That was how Ned Napier came to finish the air ship his father had
+planned, and how it happened all that summer that the papers printed
+news stories and Sunday specials with pictures of his daring
+flights, and how Major Baldwin Honeywell and other happened to speak
+of him as the Ned Napier.
+
+To return to the scene of Ned's meeting with the Major--
+
+"My name is Ned Napier," the boy began as soon as his host's
+cordiality gave him a chance, "and I am the young man the newspapers
+wrote about."
+
+"I certainly made no mistake in sending for you," exclaimed the
+soldier. "But, before I say more I want you to realize that this
+is, to me, a most important matter."
+
+"You mean it is--"
+
+"A solemn secret. I want secure your services in a desperate and
+daring adventure that will mean a great deal to me--and a great deal
+to you."
+
+"Certainly," was the boy's response. "I give you my pledge on that."
+
+A look of relief came into the old soldier's face.
+
+"If I furnished you the money," went on Major Honeywell suddenly,
+"could you produce in a short time a practical and manageable
+balloon?"
+
+Before the boy could answer the old soldier continued: "I don't mean
+one of those affairs in which ascensions of an hour or so are made.
+I mean one in which you could travel for several days--perhaps a
+week?"
+
+"No," said Ned, "it can't be done. No one has yet remained in the
+air in a balloon over fifty-two hours."
+
+Major Honeywell said nothing, but Ned could see that what he had
+told the Major had dashed some budding hope.
+
+"That is," Ned hastened to explain, "you couldn't do it unless you
+periodically renewed your supply of hydrogen. I really believe,"
+continued Ned, "that I ought to know more about what you are
+planning to accomplish."
+
+Again the white-mustached man was silent a few moments, and then he
+told without reserve the great secret. He began with an account of
+himself. Until three years before he had been an officer in the
+United States cavalry, stationed in the southwest. Then the
+President had assigned him to ethnological work. His special work
+was in the ruins of the Sedentary Pueblos. While scaling a cliff in
+this work he fell and permanently injured his left knee.
+
+Resigning from the army, he traveled for a year and then went to
+visit an old friend, Senor Pedro Oje, whose immense sheep herds in
+Southwestern Colorado had made their owner a millionaire.
+
+While here, hearing of an ancient nearby pueblo, just south of the
+Mesa Verde, Major Honeywell and his friend drove to the settlement.
+To Major Honeywell's surprise he found an old friend in Totontenac,
+the chief. As the two white men were about to leave, old Totontenac
+presented to his soldier friend an ancient funeral urn.
+
+Major Honeywell was almost paralyzed with astonishment when he saw
+that the vessel was sealed and that it bore on its side, instead of
+the conventional Aztec design, this inscription in black: "Miguel
+Vasquez, 1545."
+
+"What was in it?" asked Ned quickly when the Major came to this part
+of his narrative.
+
+"That man was undoubtedly a soldier who marched out of Mexico in
+1539 with Friar Marcos, the great explorer," went on Major
+Honeywell, ignoring the question, "and when others gave up the
+search for the famed seven cities of Cibola and the wealth of the
+Aztecs that every Spaniard believed rivaled the treasure of the
+Incas, this man kept on. Either by accident or design Miguel
+Vasquez was left by the expedition and six years later he wrote on
+cowhide and concealed in that vase one of the most valuable historic
+records extant in America to-day--confirmation that there was a real
+basis for the tales that lured the Spaniards to this region in quest
+of treasure."
+
+Stepping to a trunk Major Honeywell took from a compartment a tin
+tube. From this he extracted a stiff sheet of parchment-like
+material.
+
+"It's writing, isn't it?" exclaimed Ned.
+
+"Yes, and Spanish. It is Miguel Vasquez's last will and testament,
+written over three hundred and fifty years ago. And here is a
+translation of it. You may read it yourself. That is my secret--
+and yours now!"
+
+And these are the words that turned the current of Ned Napier's
+life:
+
+"A relation of Miguel Vasquez soldier of Spain made in the year 1546
+concerning the hidden city of Tune Cha. Coming out of Saint Michael
+in the Province of Culican I journeyed with Captain Marco de Nica in
+1539. At Vacupa I departed from him and remained now six years
+among those of this land. Three years I dwelt in the town of Acuco
+and heard often of the city of Tune Cha wherein is to be found the
+Temple of Turquoise than which none more beautiful is to be found,
+not even in Castile itself. Such I have seen with my own eyes. It
+standeth within a palace of five hundred rooms or more wherein are
+to be found priestly vessels of gold and silver. And this same
+palace or City of Priests is compassed about by a massive wall. And
+in the center of the palace standeth the Temple, facing the sun
+which is the sacred place of al Quivera, Arche and Guyas. And the
+walls of this Temple are naught but precious Turquoise even to the
+height of forty feet or more, and the pillars thereof are of gold
+and silver alternate. Knowledge of this hidden and beautiful city
+hath not been reported unto Spain nor even unto Nueva Espana. From
+Acuco it lieth thirty day's travel west of north and as I estimate
+in 36 degrees latitude in the mountains of Tune Cha. From the Rio
+de Chuco it lieth west six days' travel. Nor may it be discovered
+but by those who have knowledge of it.
+ Miguel Vasquez"
+
+"What I had hoped to do," said Major Honeywell at last, "was to make
+the most perfect balloon ever built and discover through you this
+hidden temple of turquoise treasure. You say you cannot do it."
+
+Something he had never felt before shot through Ned's body. His
+face flushed and then grew pale under the spell that was on him.
+
+"Major Honeywell," he said suddenly, "I don't know of a balloon that
+can be made to fly for a week. But if it is necessary to have one
+to do what you wish I'll make it and I'll find Vasquez's Turquoise
+Temple."
+
+
+
+
+CHAPTER IV
+
+THE CONTRACT, AND LIQUID HYDROGEN
+
+
+"I knew you'd do it," exclaimed Major Honeywell, beaming. "Now
+we'll have my friend Senor Oje up and get right at the details."
+
+"One moment, Major Honeywell. It is easy to say what I just told
+you. But it means I've got to do something no one has ever done.
+I've got to take with me--in the balloon, of course--the material to
+replace the gas I lose."
+
+"Well, that's easy, isn't it? For you--" qualified the old soldier.
+
+"I guess you don't know much about ballooning," laughed Ned.
+
+"Will money enable you to do it?"
+
+"I hope so! Other experimenters have tried to carry materials to
+make gas. I'm going to take the gas itself in a glass jar."
+
+"In a glass jar!"
+
+"Precisely. Liquefied hydrogen gas."
+
+At that moment Senor Pedro Oje, who had been summoned by Major
+Honeywell, entered the room. An almost Indian complexion and cast
+of countenance indicated his Mexican origin. What had taken place
+was related to Senor Oje, and he left no doubt that he was
+thoroughly in sympathy with the project. He soon put matters on a
+business basis.
+
+"We are to share alike in what is found, I understand," he said.
+"Major Honeywell will have a third interest because the secret is
+his. This young man is to have a third because the risk is his.
+And I am to have a similar portion for furnishing the capital. And
+that brings us to the real starting point," the Mexican capitalist
+continued. "What is it to cost?"
+
+"Ten thousand dollars at least," answered Ned instantly.
+
+"Phew!" exclaimed Major Honeywell.
+
+Senor Oje, not unused to speculative investments, gave no sign of
+surprise.
+
+"How shall it be arranged?" was his only comment.
+
+"Put that amount to my personal credit in the First National Bank--
+if you care to trust me."
+
+"We are trusting you with more than that," replied Major Honeywell
+with earnestness.
+
+"It will take me six weeks to make my arrangements. In that time,
+as I need the money, I will draw on the account," said Ned.
+
+"Very good," said Senor Oje; "I will draw up the agreement."
+
+"Now," continued Ned, addressing Major Honeywell, "what is your
+interpretation of the message of the Spaniard?"
+
+"Of course Vasquez's words must be modernized. What he termed the
+Tune Cha Mountains begin in New Mexico and extend northwesterly into
+Arizona and Utah. In many places their plateaus rise eight thousand
+feet above the sea. Their thousands of peaks and canyons are fit
+rivals of the wonders of the Grand Canyon of the Colorado. Nowadays
+they are known by many names--the Sierra Chusca, the Lokaeboka, the
+Carrisco. 'Thirty days' travel west of north' is not very definite,
+but it certainly locates the palace in the far northwestern part of
+these mountains.
+
+"The Rio de Chuco can only mean the Chusco river. The only place in
+its winding course that is six days' journey from the mountains is
+where it joins the Amarilla. This is south and east of Wilson's
+Peak, which is our landmark."
+
+"Very good," exclaimed Ned, briskly. "Now, what is the nearest
+point in civilization?"
+
+"Clarkeville, Arizona."
+
+"Then that is my starting point. This is June twentieth. I shall
+be ready by the last day of July. Of course I shall need a special
+car."
+
+"Very well," responded the capitalist. "I see you know what you
+want."
+
+"Incidentally," exclaimed Ned, "I shall, of course, be permitted to
+carry my own assistants."
+
+"Assistants? Yes, of course," replied Major Honeywell, "but they
+must be persons of discretion."
+
+"My chum, Alan Hope, who will make the ascension with me, will be
+one, and a colored boy, Elmer Grissom, who has helped me prepare for
+all my flights, will be the other."
+
+There was no dissent.
+
+"When shall I make my report?" Ned added.
+
+Major Honeywell and his friend conferred a moment.
+
+"Will five weeks be enough time for your exploration?"
+
+"I think so; perhaps less."
+
+"Then we will meet you at the Coates House in Kansas City on the
+first day of August."
+
+Senor Oje arose and lit a fresh black cigar.
+
+"It will be well for you and Major Honeywell to talk over these
+things while I see my Chicago banker," said he. And with a good-
+natured "Adios, Senores," he left the apartment.
+
+"Now, about this liquid hydrogen?" began Major Honeywell at once.
+
+"Well," said Ned, "instead of ballast, I'm going to carry reserve
+hydrogen with me."
+
+"And is that so difficult?" asked the Major.
+
+"Impossible, if you try to carry material to make the gas," answered
+the boy.
+
+"And so you are going to carry it in liquid form?"
+
+"I'm going to try, although the making of liquid hydrogen is, so
+far, pretty much a theory. It has been made only under tremendous
+pressure and at minus 423 degrees Fahrenheit."
+
+The Major whistled.
+
+"That is so cold that ice is red hot comparatively," explained Ned.
+"This work must be done, in Washington."
+
+They discussed the balloon itself, and the car and the engine for
+propelling it; where these were to be made in the East, and how they
+were to be forwarded to Chicago as they were completed. Ned himself
+was to go East at once and remain there until the last thing was
+accomplished.
+
+Ned's chum, Alan Hope, had just taken employment for the school
+vacation in a large sporting goods store not far from the hotel. A
+few minutes later Ned walked leisurely into this store and sought
+out the fire-arms department, where Alan was on duty.
+
+"Hello, Ned," exclaimed Alan, "what do you think of this?" And with
+a smile he handed him an automatic pistol he was inspecting.
+
+Restraining himself, Ned looked it over carefully.
+
+"It holds ten cartridges and it's a beauty," declared Alan.
+
+Ned weighed it carefully in his hand. "What's it worth?" he asked
+with dignity.
+
+"Eighteen dollars."
+
+"I think we'll need three of them!"
+
+Alan laughed.
+
+"And there are a good many other things I think we shall need," went
+on Ned, soberly.
+
+"This hot weather is pretty bad on some people," laughed Alan.
+"But, by the way, who are 'we?"'
+
+"You and Elmer Grissom and I," answered Ned carelessly.
+
+"And where are we going?" continued Alan, who was not unused to
+Ned's joking.
+
+"On a little run in a private car down into New Mexico."
+
+Alan looked at him a moment and then determined to have the joke
+out.
+
+"Then what are we going to do?" he asked, still laughing.
+
+"Make a trip through an unexplored mountain region in the best
+dirigible balloon ever built."
+
+Alan wondered just where the joke came in. "And then?" he
+continued.
+
+"Discover enough hidden treasure of jewels and silver and gold to
+make us rich."
+
+"Shall I get you a cabbage leaf and some ice water?" asked Alan.
+
+"Get your father's consent that you can go; that'll be all,"
+announced Ned and then, breaking into a laugh, he relieved the
+perplexed Alan by explaining what had just taken place. In ten
+minutes Alan had secured permission to be off for the remainder of
+the day and the two boys hurried away for luncheon, to revel in
+dreams of their great opportunity.
+
+By night Mrs. Napier had consented, though with tears, to Ned's
+going, and later Alan's father reluctantly did the same. As Ned was
+to leave the next afternoon and had to see Major Honeywell and Senor
+Oje in the morning it was a busy evening that the two boys spent in
+Ned's workshop.
+
+At one o'clock in the morning Alan's work in Chicago was outlined
+and Ned's needs in the East were all listed.
+
+"And now," exclaimed the tired but exuberant Alan, "it is all
+arranged but the name. What are we to call the air ship?"
+
+"The 'Cibola,'" answered Ned without hesitation, "the dream of the
+Spanish invaders and our hope of success."
+
+
+
+
+CHAPTER V
+
+A DINNER PARTY ON THE PLACIDA
+
+
+The long, heavy, limited train on which the young air ship boys were
+at last embarked on their extraordinary mission pulled slowly out of
+the station.
+
+Ned made a quick survey of the Placida. Coming out of the baggage
+end he passed first into a drawing room. In this were two sections
+that opened up into four berths. Beyond the berths a passageway led
+to a private stateroom. When the boys reached the stateroom, Elmer
+was standing at the door with a happy smile on his face.
+
+"Fo' de captain," exclaimed the colored boy.
+
+"Where are you to bunk, Alan?" Ned asked, quickly.
+
+"Oh, the crew is in the main room."
+
+"Not much," exclaimed Ned. "We're partners in this enterprise. I
+don't have any better than the rest."
+
+And in another moment he had dropped his valise alongside Alan's
+berth.
+
+"We'll keep the little room for consultations," he said with a
+laugh, "when we don't want Elmer to hear us talking about the
+Indians."
+
+The colored lad grunted.
+
+"Can't scare me wif no Injun talk," he said. "I specs I ain't half
+so 'fraid o' Injuns as I is o' dat stuff in de black box."
+
+"And it's time to attend to the 'stuff,'" interrupted Ned.
+
+They returned to the baggage room.
+
+"Now," Ned began, "the door to this car must be kept locked except
+when the train crew are compelled to come through. We, in turn,
+must be careful about fire and lights. But, for fear of accident, I
+have taken some precautions."
+
+Alan and Elmer then saw that the top of the case was fitted with a
+lid the edges of which were bound with rubber. In the center of the
+covering was a short spout.
+
+"What's the use of an air and gas proof top with a hole in it?"
+asked Alan, inspecting it curiously.
+
+"Maybe dat's to let de air in and de lid's to keep de hydrogum from
+gettin' out," volunteered the colored boy.
+
+Ned was too busy to answer the one or to laugh at the other. He had
+unlocked the lid and thrown it back. About six inches beneath the
+top of the case stood eight iron boxes--two rows with four boxes in
+each. These boxes, six inches square, were each about three feet in
+height and in each could be seen the neck of a glass vessel.
+Securely packed in their iron jackets to prevent breaking, stood the
+glass receptacles, open-mouthed and apparently empty. But down
+below the shadowed rims were soft clouds of gaseous vapor, beneath
+which reposed the precious contents that had cost Ned over a
+thousand dollars--the liquid hydrogen.
+
+On top of the square iron buckets was coiled eight or ten feet of
+rubber hose. Taking it out Ned closed and locked the lid. He then
+screwed one end of the hose onto the open spout and, springing to
+the top of the case, passed the other end out of the open
+ventilator.
+
+"Now," Ned explained, "we are in less danger. Difficult as it is to
+condense hydrogen, it is more difficult to keep it in liquid form.
+It constantly seeks to return to gas. In a closed place it might
+make trouble."
+
+Elmer had already disappeared, with popping eyes and mumbles of
+protest. Alan proudly exhibited to his friend the results of his
+share of the work of preparation. Every crate, box, barrel and
+package was numbered and labeled and securely fastened in place.
+
+On one side of the car stood five large oak tanks, looking like the
+famous beer tuns of Germany.
+
+"I can make more hydrogen in those than you've got in your black
+box," Alan exclaimed jokingly.
+
+"I'll have a better look at them in the daylight," finally said Ned;
+"and now those easy chairs in the other car would feel pretty good."
+
+"Aren't sleepy, are you?" asked Alan, forgetting that his chum had
+not slept the night before.
+
+"No," said Ned, "only happy. But I'd be happier if I had had time
+to get a good hot supper."
+
+"All ready, sah, in de stateroom," announced Elmer's cheerful voice.
+
+Both boys turned--Ned in surprise.
+
+"Supper's all ready, sah!" continued the colored boy, "and waiting
+fo' you all."
+
+In the stateroom was a sight to arouse a sleepy boy and to delight a
+hungry one. In the middle of a small table was a bunch of pink
+roses. On either side, in a dish of cracked ice, was the half of a
+luscious cantaloupe. Silver knives, forks and spoons, sparkling
+glass-ware and snowy napkins at once revealed the resources of the
+Placida's pantry.
+
+"Well, I'll be jiggered!" exclaimed Ned.
+
+"Pretty nifty, eh?" laughed Alan.
+
+"Well, if this isn't the last straw!" exclaimed Ned as they seated
+themselves. "But I want to thank you both. I didn't know how
+hungry I really was--"
+
+He was about to plunge a spoon into the fragrant, cool melon when he
+saw a folded note by his plate. Opening it he read:
+
+"Dear Ned: Good luck and good voyage. The roses are from my own
+garden. Bring me a turquoise ring.
+ MARY HOPE."
+
+It was from Alan's sister.
+
+"Shall we do it, Alan?" he cried.
+
+"Shall we?" answered Alan wringing his chum's hand. "We'll do it
+or--"
+
+"Is you all ready for dis?" asked the young chef suddenly appearing
+with a smoking broiled steak. "It can't wait no longer."
+
+And it did not have to.
+
+An hour later the two happy boys sat on either side of the table in
+the drawing room of their car.
+
+"Are you getting nervous?" began Alan.
+
+"About what?" asked Ned.
+
+"Oh, about everything. The responsibility for this car and the
+setting up of your balloon, and the trip itself."
+
+"Are you?" exclaimed Ned.
+
+"My, no, I'm not. But then I'm not the captain. But I thought you
+might be."
+
+"Aren't we getting along all right?"
+
+"Perhaps too well," Alan answered.
+
+"Never talk that way," interrupted Ned decisively. "Everything is
+happening as it does because we planned it just that way. Things
+can't go too well. That is a foolish idea. The good fortune of
+careful preparation should only confirm your judgment."
+
+This was the sort of advice Alan had to take now and then from his
+friend; but it always did him good.
+
+"Then you don't believe in good luck?" rather sheepishly suggested
+Alan.
+
+"I believe in it, yes," replied Ned, "if it comes--and I never put
+it aside. But I never count on it."
+
+Sleep seemed to have fled from Ned's eyes. Although Alan suggested
+that it might be well to turn in early and be up early, Ned insisted
+on seeing Major Honeywell's chart of the country they were to
+explore, saying that he had another night on the journey in which he
+could sleep.
+
+The chart was really only a rough pencil sketch. The instructions
+were more in detail.
+
+"This country, now a portion of the reservation of the Navajo and
+Southern Ute Indians, is a wilderness," Major Honeywell wrote.
+"White men do not visit it because the Indians will not permit them.
+Mining prospectors who have tried to do so have been murdered."
+
+"Cheerful, isn't it?" interrupted Alan.
+
+"This jumble of mountains has no connection with our two great
+western mountain ranges. The towering plateaus, cut with yawning
+canyons, are plainly the result of some special volcanic action.
+This unknown region extends over a hundred miles northwest and
+southeast, and on all sides drops suddenly into the sandy deserts.
+At Clarkeville the desert begins at once. If you will start a
+little east of north and locate the Indian village of Toliatchi,
+twenty miles away, you will be on the Arroyo Chusco. Although the
+bed of this stream may be dry it can be traced northward sixty-five
+miles, where it unites with the Amarilla, eighty-five miles from
+Clarkeville. At the juncture of these water courses, if you face
+west, the roughest part of the Tunit Chas will confront you. At
+your right will be Wilson's Peak. That portion of the Tunit Chas to
+the southwest forms the Lu-ka-ch-ka mountains. To the northeast lie
+the Charriscos. Somewhere in these mountains lie the temple and the
+treasures we seek."
+
+
+
+
+CHAPTER VI
+
+BOB RUSSELL OF THE KANSAS CITY COMET
+
+
+When the Overland reached Kansas City at nine o'clock the next
+morning the air ship boys were just finishing an appetizing
+breakfast of fruit, omelet, pancakes and coffee. The Placida, their
+special car, came to a stop at the far end of the station train
+shed, and, covered with dust as it was, and almost hidden among
+hissing engines and baggage and express cars, there seemed little
+reason for it to attract attention. Of course it was not ignored by
+the railway officials. No sooner was the train at rest than the
+depot master and the division superintendent were knocking at the
+door. They had special orders concerning the car, and immediately
+wheels and brakes were being tested and ice and water were being
+taken aboard.
+
+The railway officials made a quick inspection of the car, asked if
+anything was needed, and were soon gone. A few minutes after they
+had left a young man suddenly appeared, dodging among the cars. He
+sprang on to the rear step of the Placida, but before he could enter
+the car, the door of which had been left open by the departing
+officials, the vigilant form of Elmer Grissom blocked his way.
+
+"Who's in charge here?" demanded the stranger. "I'm a reporter and
+want to see him in a hurry."
+
+The railway officials had been admitted through the baggage portion
+of the car, but Elmer knew that this way was not open to everyone.
+He understood the need of secrecy, and politely forcing the reporter
+out of the door on to the platform he led him to the front of the
+car.
+
+"If you'll give me yo' card," he then said with dignity, "I'll take
+it in, sah."
+
+As he was about to do so, Ned and Alan emerged from the car for a
+few mouthfuls of fresh air.
+
+"Hey!" exclaimed the impatient young man, "I'd like to see the man
+in charge of this car. It's important and I'm in a hurry. I'm a
+reporter for the Comet."
+
+The boys smiled.
+
+"We are in charge," answered Ned. "What can we do for you?"
+
+The reporter seemed taken somewhat aback at seeing two youngsters
+directing a special car. His bearing changed at once.
+
+"I've been sent to get a story about where you are going and what
+you are going to do," he said with a little more consideration;
+"that is, if you care to tell."
+
+Ned puckered up his lips and thought. He had met reporters before
+and he knew what a "story" meant.
+
+"I think we don't care to say," he replied in a moment. He did not
+even care to say it was a secret. Even that admission, he knew,
+would be a basis for something that might interfere with his plans,
+
+"Our correspondent in Chicago says you left there last evening with
+a carload of new and powerful explosives."
+
+"Was such a story printed this morning?" asked Ned, eyeing the
+reporter closely.
+
+"I think not," said the reporter, "but we are an afternoon paper,
+you know. We have a report that you are on your way to Mare Island,
+California, and that you have a carload of explosives for the navy."
+
+"Was such a story printed this morning?" repeated Ned, smiling
+again.
+
+"No, it wasn't. But it will be this afternoon," answered the young
+man impatiently.
+
+"If such a report had been known in Chicago last night," replied Ned
+sharply, "it would have been in every newspaper in that city and
+this city this morning. No correspondent sent you such a story.
+You are a poor guesser."
+
+The reporter was at least four years older than Ned and Alan.
+Therefore, he gave a little start of surprise. He had been trapped
+in a trick that he had often worked successfully on many an older
+person. For Bob Russell, easily the brightest and quickest-witted
+reporter in his city, thus to be turned down by two "kids" would
+never do. Without wasting time to deny Ned's charge, he tried a
+belligerent role.
+
+"Do you deny you have newly invented ammunition in that car?" he
+exclaimed brusquely.
+
+"I deny nothing and refuse to be put in the attitude of doing so,"
+calmly answered Ned. "Although it happens you are wrong again."
+
+The young man laughed and again changed his tactics.
+
+"Well, look here, boys, what's the use of getting mad about this?
+You're working on something, just as I'm working on a newspaper.
+You've got a good story somewhere about you and I'd like to have it.
+What's the matter with being good fellows and loosening up?"
+
+"Because it is purely a business matter in which the public would be
+too much concerned if it knew what we were doing."
+
+"Well, whatever it is, it's good--I know that," replied the young
+journalist, laughing, "and I'm sorry I'm not in it with you--special
+car--flowers--traveling like railroad presidents. I'm on. But,
+say, when this thing breaks I'd like to be in on the yarn. I was
+lying. I never heard of you before the train pulled in. But you
+know the railroad people are on. They told me you had a black case
+marked 'Explosive.' That's all I know. Say, couldn't you tell me
+this--are you going through to the coast?"
+
+Ned relented a little.
+
+"Perhaps," he said smiling, "we might go to the coast."
+
+"You might?" interrupted the reporter eagerly.
+
+"Or we might stop in the mountains."
+
+The reporter looked perplexed.
+
+"Then you've got something to do with mining?" interrupted the
+impulsive journalist, "and it isn't the navy yard. But you came
+from Washington! I know that, you see."
+
+"Yes," volunteered Ned, "but we might be from the Hydrographic
+Office."
+
+"Cloud breakers," quickly interrupted the reporter again. "How's
+that for a guess? Are you rain makers?"
+
+"What are they?" innocently asked Alan.
+
+The reporter saw he was wrong.
+
+"I give it up," he said shrugging his shoulders. "You are two wise
+lads."
+
+"Not wise," suggested Ned, "but attending strictly to our business."
+
+"Right you are," answered the reporter.
+
+"I've got to leave you to have a look through the train. Sorry I'm
+not in on this. Where ever you're going, it looks good to me. When
+you come back, don't forget me. Save the story for me, Bob Russell
+of the Comet."
+
+Handing his card to the boys with a cheery "So long!" he was gone.
+The boys felt a little relieved. They had done what they could to
+protect the interests of their patrons and themselves by keeping
+their mission a strict secret. So far as Ned knew, the only persons
+who had knowledge of what they were doing and where they were going
+were his mother and sister, Alan's family, and Major Honeywell and
+Senor Oje. Not even Elmer Grissom's parents knew where he was
+bound--it was sufficient for them to know that he was with Ned. Of
+course the railway people knew where the car was to stop. Beyond
+these it was necessary for no one else to know what was being done--
+not even the manufacturers who made the balloon, the engine and
+their precious gas. But what the young air navigators desired and
+what Bob Russell wanted were two different things.
+
+
+
+
+CHAPTER VII
+
+THE MAKING OF A NEWSPAPER STORY
+
+
+Let us see whether the young reporter was baffled by the reticence
+of the secretive boys.
+
+"Every one to his trade," murmured Bob Russell, as he hastened from
+Ned and Alan, "and now, me to mine."
+
+Bob was what was known on his paper as the "depot reporter." It was
+not the most important assignment, for usually his work consisted
+only in describing such notable personages as passed through the
+city and now and then in interviewing the more important of these.
+But this day he was confronted with a mystery and it was his
+business to solve it. He acted quickly.
+
+Hurrying after the depot master, with whom of course he was
+friendly, he persuaded that official to go at once to the conductor
+of the train and ascertain the names of the boys. This was a simple
+thing, done in that manner, for even the passengers in a special or
+private car must have regular tickets. The conductor at once
+revealed the identity of the three passengers. Although Bob knew
+the conductor, he realized that he stood a chance of being refused
+even thin information if he asked for it personally.
+
+While his friend the depot master was getting this information, Bob
+quickly, but apparently carelessly, approached the head brakeman who
+had helped bring the train from Chicago. It was Tom Smithers--also
+a friend of Bob's, who made a point of knowing every employee
+running into the station.
+
+"I see you've got the Placida with you?" began Bob indifferently.
+
+"Yep," answered Tom, "and loaded to the axles. All except
+passengers. She's running light on them. Two boys and a coon."
+
+"I just had a talk with them," remarked Bob, carelessly offering the
+brakeman a cigar. "Pretty dusty, eh?" After a moment's casual talk
+Bob returned to the subject.
+
+"I guess those kids must be next--running a car with locked doors."
+
+"Locked doors!" snorted Tom, putting his cigar away for a
+surreptitious smoke. "Not on your life. Not against me. You bet
+she was open whenever I rang."
+
+"But it might just as well have been locked," said Bob. "The place
+is so jammed full of stuff. I couldn't make out what it was, but
+there was a wad of it."
+
+The unsuspecting brakeman then gave Bob what he was hoping to get.
+
+"Well, I stopped and saw it," he confessed. "I roused up the coon
+after midnight to have a look at the ropes and when I came back I
+took my time. They got a case of powder or dynamite in there marked
+'Explosive.' I didn't bother that but the rest was plain. Half the
+boxes in the car were labeled 'balloon works' or 'motor works.'
+It's a balloon show--nothing else."
+
+"Where is the car going?"
+
+"They ain't consulted me," laughed Tom.
+
+A few moments later Bob was in the office of the division
+superintendent. When he left he knew that the Placida would be
+dropped on the only siding at the little town of Clarkeville in New
+Mexico. He had also looked over the best map in the offices and
+fixed in his mind the topography of the adjacent country.
+
+Before half past nine Bob had presented these scattered facts to his
+city editor.
+
+"It's a story, all right, Bob, and a good one. Go to it," said the
+editor. And Bob did the best he knew how--in a newspaper way. On
+the suggestion of the editor he telegraphed to the representative of
+the Comet in Chicago: "Who is Ned Napier?" In a little over an hour
+he had a hundred and fifty word telegram outlining Ned's aeronautic
+career and concluding: "Why? What do you know? Napier not here.
+Family won't talk."
+
+Then Bob began his story. It was, for a reporter of his experience,
+brilliant, with good deductions, good guesses and good ambiguous
+generalities. It seemed to tell more than it really did.
+
+At four o'clock that afternoon Ned and Alan were speeding over the
+green and fertile prairies of middle Kansas in blissful ignorance of
+what Bob Russell had done. Under striking headlines appeared the
+following story:
+
+"Ned Napier, the famous young aeronaut of Chicago, passed through
+the city this morning on his way to the southwest to execute the
+most daring and important balloon journey ever undertaken in this
+country. Accompanied by an assistant, Alan Hope, and on board a
+special car packed with $50,000 worth of apparatus he will proceed
+to Clarkeville, an insignificant town in New Mexico, from which
+place he will make his hazardous flight over the mountains lying to
+the north. The aerial journey may possibly extended over the Sierra
+Nevadas as far as the Pacific Coast.
+
+"The details of the expedition are not made public, as young Napier
+has been retained by the authorities at Washington and is operating
+under a strict pledge of secrecy. The knowledge that such an
+expedition is under way was made known for the first time to the
+representative of the Comet by Mr. Napier at the Union Station this
+morning. While slow to discuss the ultimate object of his trip Mr.
+Napier talked of his plans in a general way.
+
+"'I represent the Hydrographic Department,' he said to the reporter,
+'and the journey I am about to make may extend from Clarkeville as
+far as the Pacific. I hope it will accomplish what the department
+has planned, but you know that we who are in this profession are
+always prepared for failure. My assistant and I may easily have our
+lives crushed out on the rugged peaks of the mountain chain we are
+attempting to cross.'
+
+"Mr. Napier suggested that some might conclude that he had been sent
+out as a 'rain maker,' or 'cloud breaker' in an attempt to secure
+rain for the arid plains, but he laughed at this idea.
+
+"In the government's special car, carefully safeguarded, is carried
+a large can of a new and powerful explosive. In exhibiting this to
+the reporter Mr. Napier good-naturedly said:
+
+"'I am sorry I cannot tell the public the exact character of this
+new explosive. But the secret belongs to the government.'
+
+"When it was suggested that the explosive might be destined for
+certain elaborate experiments in the unpopulated wilderness of the
+region to which the expedition is now hastening on the Limited, Mr.
+Napier would only answer;
+
+"My lips are sealed. I can say no more. But I compliment the
+Comet in discovering what all the eastern papers have missed--that a
+stupendous thing is projected and that I have the honor, with my
+friend, Mr. Hope, to attempt it."
+
+Then followed an elaborate rewritten version of what had been
+telegraphed from Chicago concerning Ned. After this was a detailed
+account of the car, not omitting little Mary Hope's bouquet of faded
+roses, which in Bob's story became "a wealth of cut blossoms, the
+tribute of Mr. Napier's scientific friends."
+
+What Bob wrote was in type by twelve o'clock. Three hundred words
+of it were telegraphed to the Chicago evening newspapers. Sharp at
+six o'clock that evening the Chicago correspondent of the New York
+World sent advice to his paper that he had a story on the mystery of
+what Ned Napier was about to do for the government. Word came back
+at once to send on the story.
+
+At ten o'clock the telegraph editor of the World in New York took
+the account just received to the managing editor of the paper.
+
+There was a minute's consultation, a nod of the head, and at twelve
+o'clock that night Bob Russell was awakened to respond to a
+telephone call. It was his own managing editor who read him this
+telegram:
+
+Managing Editor, Comet, Kansas City
+
+Send man at once to follow Chicago balloon man and discover mission.
+Advance funds and draw on us. Will share story with you.
+
+Managing Editor,
+New York World.
+
+It is hardly necessary to say that Bob Russell was a passenger on
+the Limited leaving the next morning. He was just twenty-four hours
+behind in the race, but he meant, if he could, to execute his
+orders, and was already smiling delightedly in anticipation of what
+he knew would be a contest of wits.
+

+
+CHAPTER VIII
+
+THE HOSPITALITY OF NEW MEXICO
+
+
+Clarkeville was even smaller than the boys had imagined it. The
+little depot was far more pretentious than any other building in
+sight. Beyond this was a wide and exceedingly dusty street. On the
+far side of this unpaved roadway was a row of one- and two-story
+frame buildings. Here and there was a cheaper structure of little
+else but corrugated iron sheets, while to the left, where a similar
+street crossed the railroad at right angles, there was a one-story
+cement building proudly labeled "Bank." Both streets suddenly
+disappeared in a sandy, treeless plain.
+
+Wooden awnings in front of the buildings extended over the sidewalk.
+At the edge of these awnings were a few teams and many saddled
+horses, some of them hitched to posts, and others standing with their
+bridle reins dropped to the ground. Not many persons were in sight.
+The deep and cloudless blue sky was brilliant with the noonday sun
+while a hot breezeless haze hung over all.
+
+The Limited had made its usual daily pause and then to the surprise
+of the agent had run down beyond the water tank with one car,
+switched it back onto the one siding until it stood opposite the
+musty smelling freight shed, and, quickly coupling up again, had
+gone.
+
+Ned and Alan had alighted when the train stopped. Around them the
+boys could detect the first signs of the real West. At one end of
+the station a big-hatted Mexican squatted by a hot tamale can.
+Among others idling near were some high-heeled and sombrero-topped
+cow-boys, whose easy and loose clothing made Alan envious at once.
+Even the depot attendants, with their belts and loosely knotted
+neckerchiefs, seemed gayer and freer than their brother laborers
+back in the East.
+
+With coats off and collars loosened the two boys filled their lungs
+with the tonic air, for, in spite of the heat, a certain dryness
+seemed to give life and vigor to the atmosphere.
+
+"There it is, Alan," exclaimed Ned finally, pointing away to the
+north and the distant mountains, "beyond those peaks and somewhere
+under that sapphire sky is our land of promise. We'll be in it in a
+few days."
+
+The brilliant sky, the exhilarating air and the new life about them
+filled both boys with enthusiasm.
+
+"Whoopee!" almost shouted Alan finally, throwing out his arms as if
+to embrace his friend. "All we need is an Indian or two and I guess
+we'd be out West for sure."
+
+"You may not be so anxious to see them before we start back,"
+remarked Ned. "Anyway, I promise you enough of them in this
+country."
+
+With the departure of the train, the two boys became the center of
+some attention. Strangers were not plentiful in Clarkeville, and
+when the news spread that a special car was standing behind the
+freight shed on the far side of the tracks there was an instant rush
+of idlers in that direction. Ned and Alan returned with them and
+smiling good-naturedly right and left took stand at the forward car
+steps.
+
+It was about two o'clock in the afternoon, but so anxious had the
+boys become in the last stage of their journey that they had ordered
+Elmer to put off the noonday meal until they reached Clarkeville.
+The colored boy, troubled over the notion of a good dinner spoiling,
+was waiting on the car platform for it chance to get his "bosses,"
+as be delighted to call them, into the car.
+
+Before he could do so, and while the two chums were answering idle
+questions as to whether they were a "show," Ned's quick eye caught
+sight of a more important personage. A middle-aged man, not quite
+so western in appearance as the others, but plainly as much at home
+in the saddle, rode up with a clatter and sprang from his pony.
+
+Ned advanced quickly, spurred on by the new arrival's quick "Howdy,
+strangers!"
+
+"My name is Ned Napier," explained the lad, "and this is my friend,
+Alan Hope."
+
+The rider held out his hand.
+
+"I'm Curt Bradley, and I'm the mayor of this town," he replied by
+way of introduction.
+
+"Glad to meet you," answered Ned. "You've just saved me the trouble
+of looking you up, for that would have been my first business."
+
+"Not to be over cur'ous," laughed the Mayor as his eyes took in the
+big expensive car and then returned to the two boys, "might I
+inquire the nature o' yer business."
+
+Ned laughed.
+
+"Certainly," he answered, "but come aboard first. Elmer," he said
+to the waiting cook, waiter and porter, "another plate for Mr.
+Bradley."
+
+And in spite of the wholesome-looking but bronzed Mr. Bradley's
+protest that gentleman was soon sitting with the boys before what
+was perhaps the most elaborate meal he had ever eaten. His protest
+came from the fact that he had already had his dinner, but the fresh
+fruit and vegetables and spring chicken were temptations too strong
+for him.
+
+When Ned saw that their new acquaintance was at his ease and rapidly
+becoming satisfied he lost no time in coming to the point.
+
+"Our visit here, Mr. Bradley, is, in part, a secret. I hope you
+will accept my assurance, however, that it can in no way operate
+against or damage your town or its residents or the country round
+about. I want your assistance."
+
+"Ye can hev that," came the quick answer, "and if your lay is no
+one's business, why, it ain't none o' ours."
+
+"I'm glad to hear that," answered Ned. "But there may be some who
+will not be so considerate."
+
+"When I pass the word I guess they'll all think about like me,"
+interrupted the Clarkeville official. "Ye jest tell me what it is
+you want."
+
+"First I'll explain to you that in the other part of this car we
+have the material to make a dirigible balloon."
+
+"A what!" exclaimed the Mayor, his mouth full of chicken.
+
+"A balloon that you can guide through the air."
+
+Curt Bradley dropped his knife.
+
+"One o' them flyin' machines?"
+
+"Exactly."
+
+"And kin we all see it fly?"
+
+"Certainly," answered Ned, "if you will just see that no one
+interferes with us. I shall be glad in time to show you, I hope,
+the most perfect dirigible balloon ever put together and to explain
+just how it is to be operated. But in a few days, when it is ready,
+we are going to sail away on business that is our own. And when
+that time comes curiosity must stop. If anyone attempts to
+ascertain where we are going or what we mean to do I sound warning
+now that we will do all we can to prove to him that it is none of
+his business."
+
+The Mayor looked at them in surprise.
+
+"Why," he began, "I suppose ye must be on a mighty partic'lar job.
+Are you--?"
+
+"There!" interrupted Ned. "You see you are beginning to ask
+questions. Since we can't answer them we'd rather not hear them."
+
+"Right," exclaimed the Mayor. "Give me yer word it's all fair and
+square and that ye ain't violatin' no laws and I'll give ye my word
+they won't be no more questions asked."
+
+"I'm glad to do that," answered Ned, "we want certain accommodations
+for which we are willing to pay. But we want the confidence of
+Clarkeville that we are all right, even if we are a little young."
+
+"Clarkeville is yours," laughed the Mayor, getting up from the
+table, "and now what do ye want first?"
+
+In another hour the two boys, guided by Mayor Bradley, had examined
+the entire settlement. A little way down the railroad track they
+found a rather ramshackle building, mostly tin roof, and behind it a
+large plot of ground surrounded with a high corral or fence. The
+sign read "Buck's Corral." In the East it would have been called a
+livery stable. The air navigators engaged the place at five dollars
+a day for a week or more, and put a half dozen Mexican laborers at
+work removing the few horses and cleaning out the building and
+corral. The proprietor, who owned one of the few wagons in the
+town, they also hired as a drayman at $2.50 a day for himself and
+team.
+
+Work began at once. Through Mayor Bradley three reliable men were
+employed as watchmen, and these, in eight-hour shifts, undertook the
+duty of seeing that nothing in the corral was molested in the
+absence of Ned and Alan. Then the work of transporting material
+began, the first task being the removal of the five large generating
+tanks.
+
+Alan had been thoughtful enough to foresee the need of special
+clothing, and it was not long before he and Ned and even Elmer
+Grissom were enjoying the freedom of wide-brimmed hats, stout
+shirts, thick-soled shoes, and belts. Elmer's duty was the constant
+care of the Placida, which he only left on special permission. Ned
+and Alan were free to devote themselves wholly to the agreeable and
+long anticipated task of at last "getting ready."
+
+Help was easily hired and with Buck's wagon in service the
+wide-opened doors of the baggage car seemed to give out more boxes,
+crates and bundles than a full freight car. When strangers were on
+the car the colored boy stood like a sentinel over the black case
+which was made less conspicuous by being covered with a blanket.
+And his constant injunction "No smokin', sah," soon won him a
+sobriquet, Mexicans and cow-boys alike calling him "Smoky."
+
+Elmer was relieved from picket duty in time to prepare an extra
+supper to which Mayor Bradley, Buck, and Jack Jellup, the town
+marshal, were invited. It was extra work for "Smoky," who took his
+new name with a mild protest; but when he called the crew to the
+meal it was apparent that he harbored no resentment. Jack and Buck
+took their seats gingerly, but the boys soon made all at home.
+
+"There ain't agoin' to be no pay took fur this day's work," suddenly
+exclaimed Buck as he finished a generous portion of cold sliced ham
+and potato salad.
+
+The boys laughed in protest.
+
+"I ain't seen real food in ten years," continued Buck, "and what I
+said goes. This meal's worth a week's work to me."
+
+"All I got to say, young uns," interrupted Jack Jellup, the marshal,
+"is that this 'ere town is yours."
+
+Jack's idea of hospitality was an invitation to the boys to visit
+the town saloons as his guest, but Ned arid Alan laughed and thanked
+him, pleading weariness as a reason for declining. The final
+tribute of the three guests, however, before they left, was to push
+the Placida along with crowbars until it was free of the freight
+house and stood where the evening breeze could freely find its way
+through the windows. Then with hearty "buenos noches," ("Good
+night") and promises to see that every one was on hand early in the
+morning, they left.
+
+For some time Ned, Alan and Elmer sat in camp chairs on the car
+platform reveling in the glorious starlit night. From somewhere in
+the little town came the sound of low singing and a Spanish air
+played on the mandolin. It was all so different from the life the
+boys had known that it seemed like a dream. And when their real
+dreams did come it was of the not far distant Tunit Chas.
+
+
+
+
+CHAPTER IX
+
+"CALIFORNY KID" GETS A JOB
+
+
+Old Buck's horse-corral had blossomed over night into a modern
+balloon factory. And the proprietor, with his bronco team, and the
+superintending Ned and Alan made big gaps the next day in the
+precious freight of the Placida. By noon the five casks for
+generating hydrogen, the cooling and purifying box, and the lead
+pipe and other equipment, had been transferred to the old horse
+yard. Three tons of iron turnings, forwarded by freight in advance,
+were found in the keeping of the railroad agent. It took Buck six
+trips to move this, and that consumed the afternoon.
+
+A special trip was made by the wagon just after luncheon. This was
+to transport the tool chest--practically two chests, for it was a
+large one containing both wood and iron-working tools. With it rode
+the two boys, both in overalls and ready to begin the setting up and
+adjustment of the generating tanks.
+
+After their arrival at the corral, the rest of the afternoon, in
+spite of the heat, slipped quickly away. But by night a foundation
+had been leveled in a corner of the yard and the five barrel-like
+generators were firmly anchored and connected by lead pipes with the
+cooling and purifying box.
+
+"Looks purty much like a distillery," commented Buck, who had just
+made his last trip with the iron shavings, which were now piled
+close by the casks.
+
+"And is," laughed Ned, "in a way."
+
+But he volunteered no more. In fact the whole matter was a mystery
+to every one in the town, except Mayor Curt Bradley and Marshal Jack
+Jellup.
+
+In the morning the first work accomplished was the removal, one at a
+time, of ten casks of sulphuric acid, each weighing four hundred
+pounds. It was a delicate job and not unattended with danger in
+case of a cask breaking. The boys began to realize the need of help
+of a higher grade than that of the "greasers" who had been thus far
+their only assistants except Buck.
+
+Their usual good luck seemed to be with them, however, for just in
+the middle of the work of sliding a heavy carboy of acid from the
+wagon a stranger stepped from the group of onlookers, and without
+words gave a hand to the job.
+
+Alan was about to thank him hurriedly, when the stranger said:
+"Wot's the game, son? Wot's doin'?"
+
+Alan was at first inclined to resent this "tough" familiarity. Then
+he realized that the language of the man was in his natural manner
+of speaking, and he said:
+
+"Who are you and where are you from?"
+
+"Give you one guess," laughed the stranger. "No! Can't tell a
+'bo'? Well, just tramp. Wot's dew name? I lost me card case. Me
+nom de plumb is Kid, Californy Kid. And me address is--well wot's
+de name o' dis munificent metropolis?"
+
+"Clarkeville, New Mexico," answered Alan smiling.
+
+"Well, den me address is dat. Wot's de nex' inquiry?"
+
+The man was young. His clothing was worn and greasy, his shoes were
+patched, and those parts of his face and hands that could be seen
+between smears of coal dust were red from exposure and the sun.
+
+"How do you happen to be here?" continued Alan.
+
+"Well, cul--beg pardon, son--de fact is I lost me purse and de
+brakeman on de fast freight wouldn't take me check. I was dumped.
+And I can't get away exceptin' I walk."
+
+"Then you wouldn't care to work?"
+
+"Will dis beautiful city give me coin and chuck widout work?"
+
+"I'm afraid not," laughed Alan.
+
+"Den' it's work for yours truly," answered the tramp with a sort of
+cheery humor. "But, say, boss, ye couldn't stake me to a drink and
+some chuck afore I loosen up me muscles?"
+
+"Your pay will be two dollars a day," said Alan, "but no drinking
+goes. Here's a note that will get you something to eat." And
+writing a message to Elmer the tramp was soon hurrying to the car
+for a meal. A half hour later, with his sleeves rolled up, he
+returned, riding alongside Buck on the wagon.
+
+Ned had given the new hand little attention.
+
+Now he looked him over and asked:
+
+"What's your real name?"
+
+"Gus, boss; or, spellin' it out, Gustave Lippe. How's dat for a
+handle--Lippe?"
+
+Ned looked at the young man long and sharply.
+
+"One name, they say, is as good as another out here. But I didn't
+know tramps got this far west."
+
+"Sure," answered the tramp, "It's long jumps and hard ones. It's me
+last excursion dis way."
+
+"Well," said Ned slowly, "you can work for us as long as you are not
+too inquisitive."
+
+"Dat's me, boss. I'm de clam till me two dollars per will git me to
+de next whistle."
+
+"Then you'd better arrange to board with Buck."
+
+"Dat's me lay, boss, already booked. Now show me some work. Me
+trunk was checked t'roo and I ain't nuttin' on me mind but me job."
+
+"Well, you had better spend the rest of the afternoon in cleaning up
+a bit," suggested Ned. "Here's five dollars in advance. Report
+early in the morning."
+
+"Tank's, boss," said Gus, the tramp. But he took the bill slowly.
+
+"But, you can't spend it on beer and whisky and work for us," added
+Ned.
+
+Gus shifted uneasily.
+
+"You'd better have a bath and a shave. And if you need clothes and
+can get them here," continued Ned, "I'll advance more to-morrow--if
+you show up all right."
+
+"I kin work widdout a shave," the man said, "ain't der nuttin' doin'
+to-day?"
+
+Assured that to-morrow was when he was wanted the tramp slowly and
+apparently reluctantly turned and slouched away toward the stores.
+
+"What do you make of him, Ned?" asked Alan as the two toys resumed
+work.
+
+"Too slangy, I think," commented Ned.
+
+But the final stowing of the acid soon drove the tramp from the
+minds of the boys.
+
+When the young aeronauts finally closed the corral and returned to
+the car, the sun a great red ball, was just dropping behind the
+serrated mountains of the western horizon. On the car steps, Ned
+turned and pointed to the north. Far away the dusky gray of the
+plains deepened into darker and darker shadows that ended in a low
+black mass. But here and there from the black wall rose irregular
+spires, their tops pink-tipped by the red sun.
+
+"Yes," exclaimed Alan, "the Tunit Chas--our mountains."
+
+And even though the vigilant Elmer called from within, the boys
+stood and gazed in silence until the last glow had died away and the
+land of their hopes was lost under the stars.
+
+Important as was the work to be done in Buck's corral, there was
+another vital thing to be accomplished while this progressed. That
+was the creation of a base of supplies near the navigator's field of
+work. This was preferably to be at the junction of the Amarilla and
+Chusco rivers, and that point lay just eighty-five miles to the
+north. Between Clarkeville and that spot there were no roads and,
+at this time of the year, perhaps, no water. With the best wagon
+and team they might be able to get, this trip over the desert would
+require not less than five days.
+
+It was impossible for either of the boys to go on this important
+errand, as both were needed on the spot to set up the balloon. So
+it had long since been decided that Elmer was to have charge of this
+secondary expedition. And since it was Elmer who would have to
+conduct the expedition safely to its destination and establish a
+relief camp, the colored boy had been thoroughly coached in his
+coming task.
+
+"Kin I?" the boy had said more than once. "When de Cibola gits dar
+I'll be dar. And ain't no Indians nor rattlesnakes nor hot weather
+goin' to break up dat camp."
+
+And the camp meant gasoline, water, food and a stepping stone back
+to civilization, whether the expedition ended in failure or success.
+As the boys had already planned that Buck should furnish the wagon
+and horses and guide Elmer's caravan, they had asked him to call
+that evening to talk it over.
+
+"I'm ready to start, yes, right now," Elmer had said as he served
+the good supper over which he had been laboring, "but I does jes
+nach'elly hate to turn you young gemmen over to dese greaser cooks."
+
+The boys laughed. "You don't think we can keep this up all summer,
+do you?" exclaimed, Ned. "Even 'greaser' cooks are better than
+having nothing to eat. And up there," nodding toward the north,
+"there won't be any cooks."
+
+"Don't forget," interrupted Elmer, "camp--camp--well, my camp. When
+you get dar dar'll be a good meal waitin' you and when you git outen
+de mountains I'll still be dar waitin' wid eatin's."
+
+The boys laughed again.
+
+"Like as not," suggested Alan, "if you get all that truck up there.
+You'll certainly have enough. But don't you bother about the eating.
+You just watch the water and the gasoline."
+
+"Till de snow flies," exclaimed Elmer with emphasis.
+
+"Which, right there," dryly remarked Ned as he disposed of the last
+of a generous slice of melon, "is rather indefinite."
+
+When Buck, whose real name they had discovered to be William
+Bourke--easily corrupted into "Buck"--appeared, the boys had a delicate
+job before them. Inquiry had quickly shown them that Buck's twenty-five
+years on the old Santa Fe trail as guide and an active service in the
+army as scout easily made him the man to conduct Elmer to the north.
+
+To all their long explanations and reasons Buck listened in silence.
+When there seemed nothing more to be said, Buck smothered the still
+glowing end of a cigarette between his dark weather-beaten fingers
+and said slowly:
+
+"When do we start?"
+
+It was arranged that on the second morning Buck should be ready for
+a journey of uncertain length; that the general direction should be
+north; that the final destination should be revealed by Elmer on the
+second morning out.
+
+"Soldier-like," Buck had commented, "and that's the way I like it."
+
+Buck and an assistant were to take an outfit of two wagons, each
+drawn by four horses. In the lighter wagon six barrels of water
+were to be carried for use in case the usual "water holes" were dry.
+In case of an accident, the lighter wagon and horses were to be sent
+south by the second man and Elmer and Buck were to make a quick dash
+forward with what water and supplies could be carried on the other
+wagon.
+
+Old Buck made rather light of the matter.
+
+"Injuns ain't nothin' nowadays," he had explained, shrugging his
+shoulders, "ye jest want to keep yer bearin's and git used to
+drinkin' atmosphere and ye'r all right."
+
+The contract with Buck called for thirty dollars a day in money and
+food for himself and a helper. Both parties to the contract were
+satisfied and after Buck's fresh cigarette disappeared in the
+direction of the town the boys lost no time in turning in for a good
+night's rest.
+
+
+
+
+CHAPTER X
+
+AN ERROR IN CALCULATION
+
+
+While Buck was busy getting his wagons and horses and water casks
+ready the next morning the boys were not surprised to see Gus, the
+tramp, drive up just after breakfast with the moving team.
+
+"Have you had breakfast?" asked Alan by way of a greeting.
+
+"Have," retorted Gus, pulling up his team awkwardly. "It's me
+wrappin' meself around tortillas till I feel like a bag o' corn
+meal."
+
+"I can't see that you've spent any great amount of that five dollars
+on yourself," interrupted Ned, noticing the tramp's unshaven face
+and the still visible traces of coal smoke.
+
+"Well, boss, ye'r right. Dead right. But, ye see, de barber o' dis
+growin' city only works on Saturday and me friend Buck's bat' tub
+has a leak. Anyhow, de ladies hereabouts is scarce and few. Think
+wot a swell I'll be when Sunday comes."
+
+"Come in the car. We've plenty of water, and soap too," suggested
+Alan, smiling.
+
+'"Well, boss, don't tempt me. I'm working. I can't soldier away no
+time dudin' meself up on do bosses' time."
+
+"All right," replied Ned, laughing, "every one to his taste."
+
+There was plenty of work to be done, and in a few minutes all were
+at it. The chief task this day was the unloading of the materials
+yet on the car. That had to be done by night, except in the case of
+the boxes marked "Overland," all of which had been carefully and
+specially crated for wagon transportation. Of these there seemed a
+great many, and they were all put in one pile in the space made
+vacant by the removal of the gas generators. The hydrogen case,
+covered with a blanket, stood always under Elmer's watchful eye.
+This was to be removed last.
+
+As the boys meant to stay close by their valuable outfit, they
+planned to load Elmer's caravan early the next morning and to see it
+start on its trying and dangerous trip. Then they intended to
+remove the hydrogen cask to the corral and take up their own abode
+in the same place. The Placida--with no little regret--was to be
+surrendered to the railroad and returned to Chicago.
+
+For that reason this was a busy day. Load after load of crates,
+boxes, and bundles were carried to the big corral, the teams
+stirring up the dust of Clarkeville's main street on their way. It
+was heavy work, and required care. Smoky-faced Gus was earning his
+pay. So skilful and adroit was he in executing tasks assigned him
+that Ned commented on it to Alan.
+
+While the boys were at their noonday lunch Buck appeared to report
+progress. The big wagon was to come from a sheep ranch, ten miles
+to the south. A man had gone for it and would arrive with it that
+night. The wheels of the smaller wagon were being soaked in water
+and the axles had been greased.
+
+Ned could not resist asking:
+
+"How's your new boarder, Buck?"
+
+"Ain't seen much o' him. Purty poor feeder fur a tramp. Can't get
+a tortilla down him nohow."
+
+Ned looked at Alan significantly.
+
+"Hasn't any baggage, has he?" continued Ned.
+
+"Not a stitch. Lessen you allow fur a extra suit o' underclothes."
+
+"Under clothing?" exclaimed Ned. "Two suits?"
+
+"Yep. And fine, too. My old woman washed a suit to-day and she
+'lows as how it cost more than the rest o' his outfit."
+
+"Don't you think that funny?"
+
+"'What?" responded Alan sleepily.
+
+"Why, a tramp with two suits of fine underwear?"
+
+"Probably he stole them."
+
+"And probably be didn't. A real tramp might steal them, but he
+wouldn't wear them."
+
+"Well, what do you care," laughed Alan, "whether he's a tramp or not
+so long as he's useful?"
+
+Ned was silent a few moments.
+
+"Tramp or not, that fellow will bear watching."
+
+"All right," conceded Alan, "I guess we can do that."
+
+By night the barn and horse yard of the corral looked like a
+combination manufactory and hardware store. The seven sections of
+the skeleton-like car stretched across the old horse yard like a
+disjointed snake; crated aeroplane guides, and the propeller and the
+rudder leaned against the fence, looking like the frame work of a
+house; the more compact engine, motor, radiator and fan stood ready
+for unpacking under the shelter shed, while shafts, connections and
+boxes of small parts filled a large part of the empty stalls. The
+tins of gasoline for experimental flights and the first trip to
+Elmer's camp were in a far corner of the yard, and in the wagon shed
+stood the two immense special trunks containing the gas bag and the
+Italian hemp netting.
+
+The evening meal was not as cheery and chatty an affair as the
+preceding ones had been, although Elmer had done his best in honor
+of their farewell. And the boys insisted that at this last meal the
+waiter should be dispensed with, and Elmer was put at the head of
+the table.
+
+"Yo' make me feel as if I was a startin' fo' do norf pole,"
+exclaimed Elmer. "I don't see what's de use of so much fussin'."
+
+"Well, anyway," exclaimed Ned, holding up a glass of iced tea,
+"here's luck to you, Elmer."
+
+"And de same to you," answered Elmer. "And to all of us."
+
+Rising bell was to ring at four o'clock the next morning; so the
+boys all turned in at once after they had cleaned up the kitchen.
+
+It was about twelve o'clock when a sudden call sounded through the
+car.
+
+"Alan!".
+
+It was Ned, who, clad in pajamas, was shaking his chum. The latter,
+dazed for a moment, sprang upright, soundly whacking his head on the
+upper berth, in which Elmer was snoring loudly.
+
+"What is it?" he exclaimed, rolling out on the floor. "Who hit me?
+Indians?"
+
+"Not yet," laughed Ned, shaking his "pal" into wakefulness.
+"Listen!"
+
+He struck a match, lit a candle and sat down on the edge of the
+berth.
+
+"You're a bum calculator," he began, eyeing Alan.
+
+"I didn't calculate where that berth was," answered Alan ruefully,
+rubbing a lump on the top of his head.
+
+"And you didn't calculate where we are now," somewhat excitedly
+added Ned. "And I didn't think of it until just now."
+
+"Go on," interrupted the still sleepy Alan. "If it's a riddle I
+give it up."
+
+"I suppose you know what the air pressure is to a square inch,"
+answered Ned, like a school teacher rebuking a slow scholar.
+
+"Why, 14.7 pounds, of course."
+
+"Where?" exclaimed Ned again, sharply.
+
+"Where?" echoed Alan.
+
+"Why, at the sea level-that's where. Not out here. Do you know how
+high we are above sea level right here?"
+
+Alan began to see the point and a smile came over his face. He had
+no chance to answer:
+
+"We're a little short of seven thousand feet up in the air right
+here in Clarkeville," continued Ned in about the same tone of
+exultation he might have used had he found a gold mine. "Now,
+listen. How many cubic feet of gas does our balloon hold?"
+
+That question was easy. The boys knew that as well as the
+multiplication table.
+
+"Sixty-five thousand, four hundred and ninety-three feet."
+
+"And how much weight is it going to carry?"
+
+"Three thousand nine hundred and thirty-five and a half pounds."
+
+"Exactly," went on Ned. "That's the weight we are going to carry
+figured at sea level. Did it ever occur to you that our sixty-five
+hundred feet of hydrogen can lift more way up here seven thousand
+feet in the air, than it can at sea level? Did it ever occur to my
+special engineer and calculator that as the weight and pressure of
+the air grows less our hydrogen will lift just that much more
+weight.
+
+"By the great horn spoon!" exclaimed Alan. "Give me that candle."
+
+In another moment he was at the drawing room table with a pencil in
+his hand. It did not take him long to make his calculations.
+
+"Live and learn," he exclaimed finally. "I'm certainly all you said
+was a 'bum calculator.' Our altitude here is 6,875 feet, for I took
+it to-day just for practice. And we can carry in our balloon just
+exactly 693.6 pounds more than we figured."
+
+"I thought so," laughed Ned. "It came to me in a dream, I guess.
+But you don't need to feel badly. You say I'm the boss, yet I never
+thought of it. You see, the trouble is that all the balloon
+ascensions ordinarily are made from the large cities of America or
+Europe. Who ever thought of ascending a mountain to get a start?
+But since we have done so we must figure accordingly."
+
+"And what is the first thing you are going to add?" asked Alan.
+
+"First thing?" exclaimed Ned. "First and last and in the middle,
+gasoline. We may find water in the mountains and we might even find
+food, but we're not going to find gasoline. Now we'll do part of
+our work whether Elmer meets us or fails."
+
+The incident showed the essential difference between Ned's mind and
+Alan's. Alan was careful, precise, and adept in detail. Ned had
+the "dreams" and inspirations of an inventor.
+
+
+
+
+CHAPTER XI
+
+A DISGUISE PENETRATED
+
+
+The boys, in spite of their broken slumbers, all turned out promptly
+at four o'clock the next morning. They found this hour the
+pleasantest of the day in this hot and dry region. The late moon
+was just disappearing, and over the plains swept a breeze that
+hinted of snow on some mountain peak not far away. Not a sound
+broke the stillness but the occasional cry of a skulking coyote.
+
+"Hear it, Elmer," said Alan, as the boys got busy in the baggage
+car. "You want to look out for those fellows."
+
+"I ain't feared o' no cutes and I ain't feared of no Injun,"
+solemnly answered Elmer, "jist so dem rattlers gives me de go-by.
+Dat's all I ast."
+
+Buck's big wagon had arrived and was backed up to the car and now,
+by the light of a lantern hanging above the door, the work of
+loading began.
+
+With their improved gas bag the boys had figured on a record flight
+without renewing the gas supply. They had hoped to be able to stay
+at least seventy-two hours in the air. But during a large part of
+this time they expected to drift without the engines, for they could
+not carry enough gasoline to last for more than twenty-four hours of
+engine work. By their new calculations they had more than enough
+gasoline, and according to Ned it seemed probable that the decreased
+air pressure on the bag might extend the period of flight another
+twenty-four hours, or to four days.
+
+After that all would depend on the liquid hydrogen. The remarkable
+qualities of this unique product were to be tested for the first
+time in the history of ballooning. When the gas in the bag had
+diminished by leakage through the valves and elsewhere so that it
+was no longer sufficient to carry the car, the liquid hydrogen was
+to be turned into gas which was to take the place of that lost. Ned
+had left Washington with sixteen cubic feet of the liquid in eight
+delicate Dewar bulbs, or casks. He figured that one-quarter of it
+would be lost by evaporation, leaving twelve cubic feet. This seems
+a small supply until one understands that the hydrogen increases in
+volume 880 times as it returns into gas from the liquid form. The
+twelve cubic feet of liquid, therefore, would give them a little
+over ten thousand cubic feet of new gas. And this, with the loss of
+ballast and provisions in three or four days, Ned calculated, would
+give the balloon a new life of a day or so.
+
+Therefore, the secret plan was a direct journey to Elmer's camp, a
+flight of eighty-five miles, which would bring the Cibola near to
+the foot of the mountains of mystery. After this camp had been
+located and more gasoline taken aboard the boys were to head their
+craft toward the Tunit Chas mountains. What would follow they could
+not foresee. With good luck they might be able to hover birdlike
+over the peaks, canyons and plateaus for five days. With bad luck
+they might have to come down sooner or fall. Then, if the Cibola
+failed them, they would have to find their way to the treasure
+temple and the ruined palace on foot in a rugged wilderness,
+infested with unfriendly Indians and reptiles, or struggle back, in
+some manner, if they could, to Elmer's relief station, and thus to
+civilization.
+
+Should the worst happen and the balloon fail them, the boys might be
+lost in a desolate region that is even now uncharted by the
+government. The only resources they would have would be the Cibola
+equipment and their own ability to take care of themselves. In any
+event, the knowledge that Elmer and Buck were in camp ready to
+succor them meant a good deal. And that was why the loading of the
+overland outfit had so much interest for the boys.
+
+Of tins of provisions there were many: condensed foods--German
+erbswurst, or army rations of ground peas and meat; dried potatoes;
+eggs in powdered form; preserved and salt meats; hard tack; tea and
+coffee; flour; and evaporated fruits. The water was already
+arranged for and the wagon containing the casks was at Buck's adobe
+house.
+
+On the floor of the wagon, packed in bunch grass, were the precious
+gasoline casks. On top of all came the silk waterproof tent and the
+camp equipage. Stowed under the seat was the box containing spare
+flags, a heliograph, part of a wireless telephone outfit (the other
+part was to be carried in the balloon) and compass. Two magazine
+rifles and ammunition were included in the outfit, and Elmer donned
+for the first time in his life a belt and holster to carry one of
+the magazine revolvers that Ned had bought on the day when he first
+told Alan what he had undertaken to do.
+
+By the time this work was done it was day. Then came breakfast,
+which Elmer insisted on preparing. He even demanded that he be
+given time to make hot biscuits. These, with thick slices of
+broiled ham, the last of their oranges, and hot fragrant coffee
+constituted the last meal on the Placida.
+
+As the meal came to an end the clump, clump of horses' feet in the
+sand announced that Buck had arrived and that it was time for
+breaking the "special car" camp. Alan and Elmer hastened to clean
+up the little kitchen that had given the boys so many savory meals
+and to pack up the remaining provisions, and Ned jumped off the car
+to see Buck.
+
+To the lad's surprise he found Gus, the tramp, just as dirty and
+just as cheerful as ever, proudly mounted on one of the newly
+arrived horses. Buck noticed the surprise in Ned's face and
+explained:
+
+"The helper I thought I could get fell down on me. My boarder's
+goin' with us. I guess he'll do."
+
+"You understand you don't know where you're going," said Ned,
+approaching Gus as he rolled off his horse, "nor when you're coming
+back?"
+
+"I knows dat we ride and dat dere's chuck a-plenty," smiled Gus,
+"and whichever way it is," he added lowering his voice and
+chuckling, "can't be no worse dan Buck's place--fur me."
+
+"Do you want to go?"
+
+"Well, I ain't a settin' up nights a longin' to, but to oblige a
+friend, Mr. Buck, I allowed meself to be persuaded."
+
+"Well, we'll see," said Ned.
+
+Ned rather wanted to watch this young man. Something suggested that
+the tramp was too quick witted to be made a party to their plans.
+Ned didn't exactly know what harm the stranger could do them, but he
+decided to talk it over with Alan. While Buck was hitching up the
+horses Ned turned to go into the car.
+
+They were loading from the far side opposite the hydrogen cask and
+as Ned passed the corner of the car he almost ran into the station
+agent. The agent, who was also the telegraph operator, had a
+telegram for Ned, which the boy took eagerly. Ned had sent a
+message to Major Honeywell, telling of their safe arrival, and did
+not doubt that this was some important afterthought of the Major's.
+The address ran: "Mr. Ned Napier, Private car Placida, Clarkeville,
+New Mexico." Tearing open the envelope Ned read:
+
+"Just learned Kansas City Comet has story mysterious trip for
+government starting Clarkeville. Real object not known. Look out
+not followed.
+
+"Baldwin Honeywell."
+
+With three jumps Ned was in the car and had pull Alan into the
+drawing room portion. The telegram was read again and the two boys
+looked at each other in astonishment.
+
+"How could they?" began Alan.
+
+"No matter how," answered Ned, almost out of breath. "They did and
+that's enough. Now I know!"
+
+"Know what?"
+
+Ned pushed his chum to the side of the car and pointed outside where
+Buck and his helper were at work.
+
+"Look at him," he exclaimed.
+
+"At Buck?"
+
+"No. At the tramp who won't wash his face, who has a gentleman's
+underclothes and who is so anxious to work for us!"
+
+"Well, I see him. But--"
+
+"Haven't you ever seen those sharp eyes before?"
+
+"You don't mean--?"
+
+"I do. If that isn't Bob Russell, the Comet reporter, I'm a goat."
+
+
+
+
+CHAPTER XII
+
+NED TO BOB RUSSELL'S RESCUE
+
+
+It was a time for quick and fast thinking, and Ned and Alan did it.
+Alan's instant suggestion that they denounce the disguised tramp was
+almost as quickly voted down.
+
+"So long as we didn't know who he was he had the advantage of us.
+Now that we know--" and neither of them now doubted the fact for an
+instant. "We have the advantage of him," argued Ned. "Let's turn
+that knowledge to profit. We can easily guess what he is trying to
+do. Major Honeywell's message says our real object is not known.
+This reporter has learned something, and I suspect he could have
+found quite a lot from the train crew. On that he has written a
+good enough story to attract attention. That shows he is no fool.
+And he wouldn't come out here unless he had been sent. Who would
+send him? Why, his paper, of course, to discover our real mission."
+
+"What can we do to head him off?" mused Alan.
+
+"There are two ways," suggested Ned, "and we've got to make one of
+them effective. I don't know how he has guessed but he must not
+have another guess. And he's seen a good deal."
+
+"We might have him arrested," suggested Alan.
+
+Ned thought awhile.
+
+"I'll tell you, Alan," he said finally. "The young men of the press
+to-day may write fanciful stories, and they may even 'fake' where it
+injures no one, but personally they won't lie. Let's call our tramp
+in here, confront him with his imposture and give him his choice of
+writing nothing or of being drummed out of town."
+
+"Who'll make him leave town?"
+
+"Marshal Jack Jellup wouldn't need two suggestions on that score.
+And more, he'd see that the order was obeyed. I don't like to do
+it, but I think we're justified. He's taking that chance."
+
+Again the thing was gone over, with arguments for and against, and
+then Elmer was hastily dispatched to find Jellup and bring him to
+the car.
+
+"And Buck will lose his helper," laughed Alan.
+
+"Better that than a second expedition on our heels," answered Ned
+
+"Gus!" he called, throwing open a window. "Come in here!"
+
+The tramp soon stood before them.
+
+"Geel Dis is a swell joint," were the tramp's first words as with
+apparent awkwardness he entered the car.
+
+Ned acted as spokesman.
+
+"You say you've promised Buck to go with him without knowing where
+you are going?"
+
+"Dat's about de cheese."
+
+"Well, we are willing. But I may as well tell you that this is a
+secret expedition. If you go you must promise that you will not
+tell anyone what you see or hear."
+
+The tramp's face suddenly took on a peculiar look, but it was gone
+as quickly.
+
+"I gives me woid. I won't open me trap to no one."
+
+"Meaning you won't say anything about it?" smiled Ned inquiringly.
+
+"Dat's it. Mum's de woid. I won't open me trap."
+
+"Nor write anything?"
+
+The furtive look came back, this time more pronounced.
+
+"Me to write! Wit wot? Me new typewriter?"
+
+"That isn't an answer. Do you promise, if we send you with Buck,
+that you'll neither tell nor write nor make known in any way what
+you learn about what we are doing?"
+
+"Say, look here, boss. Quit yer kiddin'. Me name is Lippe and
+mebbe I shoot it off a bit too frequent now and then, but you don't
+need to be afeered o' me peachin' to de udder'Bos.'"
+
+"I'm not afraid of that," continued Ned. "We don't care what you
+tell all the tramps this side of Kansas City. But we don't want you
+to print anything more about us in the Comet."
+
+Hardly a flush came on the tramp's face. There was a quick movement
+of the lips as if he were about to make protest and then he laughed
+outright.
+
+"Bob Russell," said Ned, also laughing, "would you like the use of
+our bath tub for a few moments?"
+
+"Would I!" laughed the young reporter rubbing his tinted and smoke
+begrimed hands together as if to wash them. "Well, I guess I would.
+My hands are up. What's next?"
+
+"Wash up and we'll see," exclaimed Ned.
+
+The young reporter was still laughing. "And if it isn't too much
+trouble," he asked, "would you mind if Buck took his check over to
+the depot and got the suit case that it calls for? Then we'll talk
+business."
+
+In less than twenty minutes the sun burnt, dirty Gus Lippe had been
+transformed into the dapper Bob Russell. When be reappeared in
+fresh linen, outing clothes and a natty straw hat, he was still
+laughing. Approaching the group in the drawing room, where Marshal
+Jack Jellup had now arrived, the young reporter took out his pocket
+book and a five dollar bill.
+
+"I'll pay that back first," he began; and then noticing one of his
+cards he politely handed it to the marshal. It read:
+
+ROBERT RUSSELL
+KANSAS CITY COMET
+
+"Ye'r a purty fresh kid," sneered Jellup.
+
+"At your service, Mr. Officer."
+
+Jellup had already received an explanation of the whole affair and
+was aching to exercise his authority.
+
+"Ye'r an impostor," he began, "and ef ye hadn't been caught, ye'd
+have taken money on false pretenses. I was onto ye."
+
+"Oh, now," interrupted Bob, "at two dollars Mex per day I'd have
+given good value."
+
+"Mebbe," retorted the marshal, "but these gentlemen hev come here on
+particular business and they came like gentlemen. The officials o'
+this city hev give their word that there shouldn't be no interferin'
+with their plans. And thet's what you're a-doin'. Now git!"
+
+Ned broke in:
+
+"One moment, Mr. Marshall"
+
+"Oh, that's all right, Mr. Napier," exclaimed the reporter, "he
+doesn't mean just that. He knows I don't have to leave here so long
+as I obey the law."
+
+"Ye don't, don't ye?" retorted the marshal. "Well, there ain't no
+back east law down here. Our law books mebbe got all burnt up. And
+mebbe I happen to be purty much o' the law myself. Ye'll git and
+git quick."
+
+Again Ned interfered.
+
+"I suppose if we ask you to permit Mr. Russell to stay here he can,"
+he asked.
+
+"Well, I reckon that would be so. Ef ye ask it I reckon I'll have
+to," he replied surlily.
+
+Ned and Alan held a brief consultation.
+
+"We have decided to ask the authorities to permit you to remain here
+on one condition."
+
+The, intelligent face of Bob took on a quizzical air as he waited to
+hear the condition.
+
+"That is," went on Ned, "that you give us your word that you will
+not make known anything you have seen here, or of our plans so far
+as you may know them."
+
+Bob's answer was immediate.
+
+"I can't do that," he said, "I was sent here to do just that thing,
+and as quickly and as fully as I can. You ought to understand, and
+do, I think, that I have a duty to perform. I've taken the trouble
+to come all the way out here to get a story. I've got it and of
+course I'm going to use it. I should be false to my duty, to my
+employers and to myself if I promised not to do this."
+
+"But you don't know our story."
+
+"And I'm sorry. But I should have known it all if I had had a
+little better luck."
+
+"Then you won't promise?"
+
+"Decidedly not."
+
+The boys showed that they were as stubborn as he.
+
+"Then we'll see that you learn no more," Alan exclaimed angrily.
+
+Bob smiled. "You can't take away what I already know, and it will
+take a pretty long story to tell all I am going to guess from what I
+have seen."
+
+As he spoke his eyes were on Major Honeywell's chart of the Tunit
+Chas Mountains, which had carelessly been left lying on the table
+where it had been in use during breakfast in the last explanations
+to Elmer.
+
+Ned's face reddened in new anger. He did not resent what the young
+reporter was doing; he even realized that he might do the same thing
+himself; but he was chagrined to find himself caught in such a
+simple manner. That was a big piece of additional information for
+Russell to have, and Ned knew it. Hard as the thing was to do he
+would at least put the young man out of the way of further
+discoveries.
+
+"All right," he exclaimed, "we've tried to do the fair and decent
+thing, and if you want to be stubborn Marshal Jellup can do as he
+likes."
+
+"Git!"
+
+It was the marshal who spoke and he did so as if it were a pleasure.
+
+"I'll take the Limited west to Gallup at noon," said Russell, "if I
+can stop it and catch the eastbound train there to-night."
+
+"Then ye'll flag it along the road," shouted Jellup, "fur ye'll get
+out o' here on foot and in a hurry."
+
+"On foot?" exclaimed Russell in surprise.
+
+"That's what I said an' ye heerd me."
+
+Russell looked in appeal at the two boys.
+
+Ned was mad, and mad all over.
+
+"You are so quick to have your own way," he said, "you can't blame
+us."
+
+"All right," was the cheery response, "it'll lend a bit of local
+color to the story. Goodbye, boys. And good luck to you. I'll see
+you when you come back."
+
+"Remember," said Alan relenting a trifle, "we'll let you stay until
+we leave if you'll promise to write nothing."
+
+Bob laughed again.
+
+"What good would that do me? No experience means anything to me
+that I can't turn into copy. And as for walking--I'd walk from here
+to Kansas City or crawl before I'd lie down on my shop like that."
+
+"Come on, kid, get busy," exclaimed Jellup again. "An' when ye
+start, don't bother about lingerin', because I'll be hangin' around
+and I'm good with this at some distance."
+
+As he spoke he drew a Colt 44 and tapped it.
+
+"Never fear, Mr. Jellup," laughed Bob. "I suppose I can express my
+suit case to the next town?"
+
+"Ye can't do no business in this city, d'ye hear? Now, come on."
+
+"Say, partner," interrupted Bob with his usual good humor, "if you
+will let me take a snap of you I'll make you celebrated. 'Famous
+gun man' of New Mexico. It'll be great."
+
+In another moment the nettled marshal had Bob by the shoulder and
+was whirling him out of the car. On the steps he threw the suit
+case onto the sandy plain and then pushed the reporter roughly down
+the steps. Ned and Alan stood, with flushed faces, watching the
+reporter pick up his hat and suit case. Then young Russell made a
+remark they could not hear and the marshal's revolver flashed in the
+air. They could see the boy's face grow pale at last, but as he
+straightened up the two men disappeared around the freight house.
+
+Like a flash Ned was on the ground and after the marshal and his
+victim. Alan and Buck came running in the rear, for the alert Buck
+saw that something was in the air. It was early day and only a
+straggler or two was in sight at the depot. The sun, already
+mounting high, foretold a day of depressing heat. The steel lines
+of the railway stretched interminably eastward toward the first stop
+forty miles away.
+
+Bob Russell, pale but defiant, stood in the middle of the track, his
+heavy suit case in his hand.
+
+Suddenly there was the crack of a revolver and the dust flew about
+the young reporter's feet.
+
+"Jist as a sample!" roared the angered Jellup. "The next one'll be
+higher up." And his trembling finger pointed down the hot sandy
+track.
+
+There was nothing more to be done. The pale-faced but nervy
+reporter turned toward the east and started slowly down the track.
+
+Ned ran forward.
+
+"Russell!" he shouted, "Russell!"
+
+As the reporter paused and turned, hearing his name, there was a
+second report of the marshal's revolver and Russell's suit case flew
+from his hand, ripped and torn ragged by a forty-four bullet.
+
+The smoke of the explosion puffed upward and, where it had been, the
+marshal saw Ned Napier's automatic magazine revolver under his nose.
+
+The boy was white with indignation. The possible serious results
+that might come to him and his plans meant nothing in his anger at
+such a dastardly act.
+
+"It isn't a Colt," he said with dry lips, "but, if you make another
+move like that it's got ten shots and they come out all together."
+
+
+
+
+CHAPTER XIII
+
+QUICK JUSTICE IN THE WEST
+
+
+Jack Jellup, marshal and "bad man," was never more surprised in his
+life. But Jack was no fool, and something in Ned Napier's eyes made
+the westerner conclude instantly that he had unexpectedly and
+unquestionably "barked up the wrong tree." For a few moments the
+marshal and the young aeronaut stood facing each other and then
+Jellup sneered:
+
+"Do you reckon you'd better run this town?"
+
+"No, nor you," quietly answered Ned, "and if that's the way you are
+going to do it you can settle with me right now. I'm going to stand
+on my rights."
+
+He was conscious that Russell had hurried back and was behind him.
+Another second and there was a sharp click. Both Jellup and Ned
+turned to see the nervy young reporter with the torn suit case open
+on the ground at his feet. A snap shot camera was in his hand. His
+face was white, but there was a trace of his usual smile on it. Ned
+wanted to laugh too, but the situation was too serious.
+
+"I've got you both," said Bob, a little nervously, "and if it's a
+good one I've got a dandy--'shooting up the town or the bad man
+covered'--"
+
+Had it not been for Ned's lightning-like action these might have
+been Bob's last words. Jellup's pistol had flashed once more, but
+as it dew into position Ned's own weapon rose with it under Jellup's
+right hand and the marshal's shot passed over Bob's head. Before
+Jellup and Ned could recover themselves Bob's camera was on the
+ground and the reporter had his own revolver, which he had grabbed
+quickly from the suit case.
+
+In the center of this group now stood, unarmed, Alan Hope and old
+Buck. Almost at the same time a dozen men, attracted by the melee,
+had also intervened and had taken charge of the three excited
+combatants.
+
+Pushing the crowd right and left appeared the stalwart form of Mayor
+Curt Bradley, weaponless, but with the stem face of one who gives
+orders that cannot be ignored.
+
+"Put 'em up, every one of you," he exclaimed; "do ye hear? Put 'em
+up."
+
+"Ye'r both under arrest," shouted Jellup to Ned and Bob.
+
+There was a quick explanation and then Mayor Bradley, still very
+stem of face, ordered everybody across the street to his office
+above the drug store. Men seemed to spring out of the ground, and
+the room was instantly packed to suffocation. Marshal Jellup made a
+formal charge against the two boys of "resisting and interfering
+with an officer" and then each told his story. The decision was
+immediate. Mayor Bradley ordered that both boys be released and the
+court be instantly cleared.
+
+Jellup made his way noisily toward the door, his face white with
+rage. Apparently a number present were his friends and cronies, for
+the looks of sympathy that he got turned into open murmurs of
+dissent.
+
+Mayor Bradley was on his feet at once.
+
+"What's the matter?" he began incisively. "Is there some one here
+who wants to appeal from my decision?"
+
+The hubbub subsided but there wag no response.
+
+"The time to make any complaint about my decision is right now and
+to me," went on the tall Bradley, looking over those in the room.
+
+But no one apparently cared to take up Jellup's cause. When the
+spectators had gone the Mayor, who had sternly watched the slow exit
+of the last loiterer, turned to the boys.
+
+"I thank you, Mr. Bradley," exclaimed Ned earnestly.
+
+"And I want to thank both of you," quickly added Bob Russell, taking
+the hand of each. "I'm the cause of this and I'm sorry. I guess
+you saved my life twice," he added, wringing Ned's hand. "If it
+hadn't been for you the Comet certainly would never have heard from
+me again. I guess that, puts all my obligation up to you."
+
+"No," said Ned, "I can't let you say that. You have your own duty
+just as I have mine. We'll go over to the car and wait for the two
+o'clock Limited. Then you are at liberty to go and write your story
+and do its you like."
+
+"He don't have to leave," interrupted the Mayor; "this is a free
+town and it's going to be an orderly one."
+
+"And I'm not going to," broke in Bob. "You've got yourself in a
+muss over me and some of these soreheads may try to make you more
+trouble. If you'll let me, I'll stay to the end and if it comes to
+a mix-up I'm going to be right there with you."
+
+Mayor Bradley smiled and old Buck slapped the reporter on the back.
+
+"But how about the story you say you are going to write about us,"
+asked Alan.
+
+"There wouldn't have been any story if it hadn't been for Mr.
+Napier," replied Bob. "And there isn't going to be one until he
+tells me to write it. It's up to him."
+
+Ned was looking out of the window at the curious loungers standing
+in the street. He was thinking of the work yet to be done and of
+all the difficulties that the discomfited marshal might put in his
+way. It wasn't a "picnic proposition." He didn't fear for himself,
+but the thought of his expensive and delicate outfit and of how
+easily it might be irreparably injured was not reassuring.
+
+"Russell," he said finally, "I think we need you. If you care to
+stay with us we'll be glad to have you. It isn't because I don't
+want to be bluffed by Jellup, but because you are game. If you'll
+go with Buck and Elmer, I'll try to make it worth your while--some
+time--and you shall be the historian of this expedition--when the
+time comes to write its story."
+
+Am hour later the delayed overland expedition was on its way toward
+the desert. There had been a quick shopping expedition in the
+stores of Clarkeville and Bob Russell, in a new hat and boots and
+various other articles of clothing, most of them too large for him,
+sat proudly on the driver's seat of the second wagon. Around his
+waist was a new cartridge belt and holster carrying Ned's gift, a 44
+revolver--"for game or rattlesnakes," as the boys expressed it, but
+the weapon was not concealed when the little cavalcade traversed the
+main street of the town, and if Jellup was an onlooker Ned felt sure
+that the outwitted marshal would think twice before again molesting
+the expedition.
+
+"All set," laughed Bob, as the final farewells had been said, and he
+held up his camera, "now for the real thing."
+
+Ned and Alan were now alone. To tell the truth, the excitement of
+the morning had been rather trying for them, but if it left them a
+trifle nervous they soon forgot their apprehension in making the
+last of the transfer. There was now another reason for abandoning
+the car. With headquarters established in the corral they would be
+near the balloon and its equipment, and if Jellup should permit his
+ill will to develop into some overt act, they would be in a position
+more easily to protect themselves. For that reason a number of
+their "greaser" assistants were taken to the car before noon and the
+hydrogen cask was loaded on the small wagon and carefully freighted
+to the corral. Then followed the remainder of the provisions and
+the personal belongings of the boys. Early in the afternoon the
+Placida was closed and turned over to the railway agent.
+
+
+
+
+CHAPTER XIV
+
+BUILDING AN AIR SHIP
+
+
+When Ned announced to Alan that they would at once unpack and test
+the motor--"for we might as well stop if the engine isn't right," as
+he put it--all thoughts of the troubles of the early day vanished.
+And the motor certainly was a beauty. Though some expert had
+recommended the French motor, Ned had preferred to use one made in
+America, not only because he had been able to get it quicker but
+because he believed it as good as the foreign make.
+
+The engine had eight air-cooled cylinders, in two sets of four,
+placed at an angle of ninety degrees to each other. The crank case
+was of aluminum and the shaft of vanadium steel, hollow, and
+specially treated to insure toughness. All the studs or bolts were
+of the same steel. Complete, with balance wheel, it weighed two
+hundred pounds. The ignition was accomplished by six dry batteries
+and a single-wire vibrating coil. It was rated at fifty horsepower.
+
+So exactly had the preliminary work been done at the factory that in
+two hours the boys were able to have the engine bolted to the
+section of the car where it was to be used, and before evening the
+radiator tubes and pump of the cooling system were also in place.
+Temporary connections were set up and the sparking wires attached,
+and then the reservoir was filled with gasoline. A little jar as
+the wheel was turned, then a couple of sharp explosions, and the
+engine fell to its work as if it had been running for weeks.
+
+Ned shut it off after a moment's critical inspection.
+
+"Let her flicker!" pleaded Alan. "We've waited so long for a real
+one that I like to hear her buzz."
+
+"We'll let her buzz when we can use the buzz," laughed Ned.
+"Gasoline is gasoline, you know."
+
+Night did not stop the work of the eager lads. As soon as they had
+eaten a light meal, Ned and Alan, with a couple of lanterns and a
+half dozen of candles, began to adjust the sections of the car.
+These, seven in number, when joined, were 54.12 feet in length. The
+American spruce frame and the aluminum joints were all intact. This
+work finished the day.
+
+Blankets on the rough floor were good enough for the explorers that
+night. The luxury of the Placida's mattresses and fresh sheets was
+missed, as was Elmer's skill as a chef when it was time for
+breakfast the next morning. The boys were not so indifferent about
+this meal as they had been about that of the evening before. They
+had no stove, but they took the time to arrange a regular camp in a
+comer of the corral. A little fire was soon burning, at which they
+made coffee and toasted some bacon. This, with hardtack and some
+preserved fruit, they thought was enough, for they were determined
+not to disturb the carefully packed provisions that were to be
+carried in the balloon.
+
+"Have you had enough?" asked Ned as the last piece of scorched bacon
+disappeared.
+
+"Enough?" answered Alan. "A regular banquet!"
+
+ Just then there was a loud thump on the closed door of the barn.
+
+"The hands are arriving," explained Ned, and he hastened to open the
+door.
+
+A few of the workmen were there, but the knocking had been done by a
+pleasant faced woman--apparently a Mexican. A black shawl covered
+her head and one arm. It was Mrs. Bourke, Buck's wife.
+
+"I thought," she said smiling, "hungry."
+
+Without further words she threw back the shawl and revealed a small
+tin pail. The appetizing odor made Ned's mouth water. In the
+bottom of the bucket were frijoles, or boiled and fried Mexican
+black beans cooked in pepper, and on top of these were a half dozen
+smoking hot tortillas or corn cakes.
+
+"Mrs. Buck," exclaimed Alan, "you have saved our lives!"
+
+All recollection of his recent banquet seemed to have disappeared,
+and so did Mrs. Bourke's bucket of beans and cakes, in double-quick
+order. The reward was a bright silver dollar for the thoughtful
+woman and a contract that she should come three times a day and
+prepare the boys' meals. It would have been easier to have gone to
+Buck's home, only a short distance away, but the boys were now
+determined to stay in the corral, or leave it only one at a time.
+However, they soon developed a taste for Mrs. Bourke's peculiar hot
+wholesome dishes and these, with what provisions they had on hand,
+were a fair substitute for Elmer's cooking.
+
+The frijoles having been disposed of, Ned at once went out, and was
+fortunate in finding a load of rough lumber and a sort of jack-
+carpenter. With the help of the boys a four foot-high series of
+"horses" or frames was set up in the center of the corral. This was
+for the car to rest on while it was being assembled. It was
+elevated so that the propeller and aeroplanes and rudder could all
+be tested after being set up. The propeller, 11.48 feet in length,
+revolved in bearings four feet above the bottom of the car.
+
+After noonday refreshment the middle section of the car, to which
+the engine was already attached, was carefully lifted into place
+with the aid of the workmen, and then the laborers were paid off and
+dismissed--all except the watchmen. From now on there was nothing
+that the boys could not do themselves, and they wanted to be
+undisturbed and alone. The putting together of the car was a treat
+of which they had long dreamed and they were happy in their work.
+
+The remaining sections were easily laid on 'the "horses" and then
+came the bolts and the bracing with piano wire. When brought
+together the fifty-four foot long skeleton was in shape much like a
+cigar. The main frame was six feet high, tapering to five feet at
+each end. In depth the dimensions were the same. The engine rested
+on the floor of the middle section and was accessible in all its
+parts from that compartment. An elevation of the floor in the
+forward part of this section made it possible for one to stand high
+enough to have an outlook in all directions through openings in a
+hooded elevation that projected above the top of the section.
+
+This hood was of a waterproof silk, coated with powdered aluminum,
+that metal being used because of its semi-incombustibility. This
+silk also covered the sides of the central compartment, making a
+wind-, rain- and waterproof cabin. The lookout windows on all four
+sides were covered with isinglass. The bottom of the framework of
+the car forward and aft of the engine compartment had a ladder-like
+flooring of spruce, inserted more for strengthening the car than for
+service. But on top of the car, reaching from end to end, was a
+continuous runway two feet wide which could be used in hurriedly
+visiting either propeller or rudder. This runway was protected by
+guide ropes of Italian hemp running through posts extended upward
+from the sides of the car. The top of the engine compartment was
+completely floored, making a platform 6 x 6.12 feet square. This
+was surrounded by a protecting network, and Alan named it the
+"bridge."
+
+A light rope-ladder extended into the engine cabin from an opening
+in the roof, making the top floor space or bridge and the upper
+runways quickly accessible. The gasoline reservoir, just forward of
+the engine, was connected with the bridge by a copper supply pipe.
+The extra supply of gasoline was to be carried on the bridge in the
+open air, and lashed to the netting instead of being stored in
+permanent reservoirs as is the usual practice. This was in order
+that the empty vessels might be thrown overboard when it was
+necessary to lighten the balloon.
+
+The other sections of the car were each 8 feet long and decreasing
+in height from 6 feet next the cabin to 5 feet at the end of the
+car. In the two sections just forward of the cabin and in the two
+just aft provision had been made for attaching the eight liquid
+hydrogen casks--four at each end. As this liquid was reconverted
+into gas the light sheet-iron casings might likewise be cast
+overboard to lighten the balloon. As needed, the liquid hydrogen
+jars, coated with mercury, were to be taken from their casings and
+carried to the bridge where the reconverter was located.
+
+Aft of the engine cabin was the store room for water and provisions.
+The grooves and rods for the counterweights and equilibrium adjuster
+ran in the middle of the upper footway and the propeller shaft
+rested on the bottom of the forward section of the car.
+
+At ten o'clock that evening all the work on the car was finished
+except the buckling on of the aluminum silk sides and the hanging of
+the propeller, the rudder and the aeroplane sides. It was as long
+and as hard a day's work as either of the boys had ever done. They
+were dead tired, but happy, and after a sousing wash-up they got
+into their pajamas and, throwing their blankets on the floor of the
+little office, were soon fast asleep.
+
+
+
+
+CHAPTER XV
+
+HOW JACK JELLUP LOST AN ARM
+
+
+In spite of his fatigue Ned did not sleep soundly. It had been
+threatening a thunder storm all evening and the increasing
+oppressiveness of the air made the young, aeronaut wakeful. The
+long whistle and jarring stop of the midnight local train finally
+fully aroused him. In the west the thunder was rumbling and great
+sheets of heat lightning promised a storm in a short time. After
+slipping out into the corral and seeing that the waterproof silk
+sides of the car were securely buttoned around the engine Ned
+returned and again tried to go to sleep.
+
+But his restlessness continued. In his early sleep he had had a
+vivid dream about the wagon expedition. In this he thought that
+Marshal Jack Jellup had followed Elmer, Bob and Buck and set fire to
+the wagons while his friends were asleep in camp. It was a relief
+to awaken and find that the flash of light was lightning and not, as
+he had imagined in his dream, an explosion of the gasoline carried
+in Buck's big wagon. He lay awake awhile regretting the quarrel
+with Jellup, and then he sank into a doze again.
+
+But his active brain would not rest. Again he fell into a dream.
+This time the picture was very real. The big balloon had been
+finished and launched. A thrill ran through him as he felt the
+monster craft poise and waver and then slowly rise above the corral.
+He could hear the cheers of those gathered about. But in the midst
+of them be heard the sudden crack of a revolver. Jack Jellup had
+put a bullet through the silken bulk of the bag. The cold
+perspiration broke out on Ned's forehead.
+
+The dream was so real that he thought he could hear the taunting
+voice of Jellup. In feverish excitement Ned sprang upright, to find
+a pair of strong arms clasped about him. He did not cry out. A
+wave of cold fear seemed to benumb his tongue and brain. He knew
+this was no dream.
+
+Forced onto his back, his face and eyes partly covered by the
+shoulders of his sudden captor, Ned's returning consciousness made
+him aware that there was a dim light in the office.
+
+"It's Jellup, Ned," exclaimed in a whisper a sudden voice which Ned
+instantly recognized as Alan's.
+
+"No more from you," exclaimed a rough voice in quick reply. "Here's
+the rope, Domingo."
+
+The man on top of Ned knew his business. Almost before the boy
+realized what was being done his hands and feet were caught in
+dexterous knots and he was helpless.
+
+"Now," continued the other voice, "let's have a few minutes' talk."
+
+Ned's assailant had arisen, and for the first time the boy could
+look about. In the center of the room, with a sputtering candle in
+his hand, stood the revengeful Jellup. His companion Ned at once
+remembered as one of the noisy court room spectators of the day
+before. Between the two, clad in his pajamas and similarly bound,
+was poor Alan.
+
+"Ye can stand or set, jist as ye like," began Jellup. "Me and me
+deputy hev made this little visit to ye fur a purpose. The citizens
+of this town is tired of yer carryin's on and they've just delegated
+me to ascertain what it all means. We got a purty good idee."
+
+"Well, what is your idea?" interrupted Ned, slowly regaining his
+composure and his natural defiance.
+
+"My idee is that ye don't need no flyin' machine anywhar except to
+git away quick and what we want to know is what air ye goin' to take
+with you when ye fly away?"
+
+"Nothing that doesn't belong to us," answered Ned, "if that is what
+you mean."
+
+"Ye ain't, eh? I suppose ye don't know that thar's enough cow money
+in our bank to be worth stealin'?"
+
+Both Ned and Alan looked at each other astounded.
+
+"You don't think we look like safe robbers, do you?" began Alan.
+
+"Ye look just slick enough fur that and more," retorted the marshal
+who had placed the candle on the table and roughly pulled Ned to his
+feet. "But I didn't come here to argy. Ye began by vilatin' the
+law and ye didn't come the way down here for no fun. Ef that ain't
+yer game, and we don't put it above ye, what's yer lay?"
+
+"There's only one answer," said Ned. "None of your business."
+
+The marshal shoved Ned nearer the table.
+
+"Mebbe ye want to apologize fur that little bluff of yers
+yesterday--"
+
+"No," said Ned, "but I'll accept yours."
+
+Jellup's right hand was on his revolver.
+
+"I ain't hyar to make no threats," he exclaimed, "and ye don't need
+to be afeered that I'm going to shoot ye. But I've got just one
+other little proposition. Ef ye don't cotton to that, why, thar
+ain't agoin' to be no Fourth o' July balloon ascension around hyar."
+
+Ned straightened up.
+
+"Your proposition can't be a fair one or you wouldn't come like a
+thief at this time of night--"
+
+Jellup's pistol flashed in the air but fell back again as the
+marshal's left hand shot upward and struck Ned full in the face.
+Even as the tears sprang into the bound boys eyes and pain and anger
+flushed his pallid face, the cowardly Jellup fell backward and
+stumbled to the floor. Alan, standing just behind the man, had shot
+his knees forward, striking Jellup's legs in the hollow of his
+knees, and, thrown off his balance, the westerner lay sprawling on
+the floor. Before the marshal's confederate could interfere, Alan,
+tightly as he was bound, had flung himself on top of Jellup and with
+all the power he could throw into the act had butted his head into
+the marshal's face.
+
+Am oath and a cry of pain indicated how true the stroke had been.
+Both Ned and the companion of Jellup sprang forward at the same time
+and the four fell in a silent distorted heap. But the encounter was
+unequal. In another moment both boys were lying side by side on the
+floor and their captors stood over them. Even in the half light of
+the little room both boys could see the blood-smeared cheek of the
+marshal.
+
+Jellup's hand was on Domingo's arm holding him back from further
+attack on the helpless boys and the marshal was restraining his
+anger as a snake withholds its venom until it strikes.
+
+"Purty good," sneered the marshal, "and the funny thing is ye hain't
+got a bullet through ye fur it. But my business ain't with dead
+ones. Onct more, air ye goin' to say what ye'r a plannin' to do?"
+
+"Since it doesn't concern you in the least," said Ned, slowly, "no."
+
+Jellup was silent a moment.
+
+"Fur kids ye seem to have plenty o' money. Ye'r purty free
+spenders. I'll give ye one more chance. Ef ye've got a thousand
+dollars handy fur a kind of a bond as it were I guess that'll sort
+o' protect us."
+
+"You mean for bribery?" exclaimed Alan.
+
+"No, just instead of stealing," angrily added Ned. "We haven't a
+thousand dollars and if we had you couldn't get a cent of it. And
+to save you some trouble I'll say that what we have is in your
+bank."
+
+Another half-uttered oath sounded on Jellup's lips.
+
+"In thet case," retorted the marshal, "we'll jest show you that we
+mean business. That's a lie about the bank. Produce or take the
+consequences."
+
+"Help yourself," replied Ned, "if you think we are lying."
+
+"I ain't no pickpocket," retorted Jellup, "this is official. I tell
+ye it's a bond and this is yer last chanct to make good."
+
+The boys remained silent.
+
+But Jellup's companion was already busy. Leaving the marshal to
+stand guard over the boys he made a quick search of their clothing.
+But Ned was not so used to money as to be careless in the handling
+of it and the six hundred dollars that he had in gold was in a belt
+carefully concealed in the top of the liquid hydrogen crate, which,
+for safety, had been stored in a corner of the room.
+
+When the silent Domingo threw down the working garments of the boys
+he took up the candle and began a tour of the room. The big black
+liquid hydrogen crate attracted his attention and he approached it.
+The red "Explosive--no fire" letters of warning apparently meant
+nothing to him, but Jellup halted him with a sharp warning, followed
+by a few words in Mexican. Domingo handed the candle to Jellup and
+the latter stepped toward the box.
+
+"That means what it says," exclaimed Ned quickly and sharply.
+
+The crate stood as it had been carried from Washington with the top
+on and the connecting hose extended upward through a hole made in
+the low roof in order that the slowly accumulating reconverted gas
+might escape in safety.
+
+"Mebbe," said Jellup, "mebbe yes and mebbe no. I guess they ain't
+nothin' agoin' to explode that ain't set afire."
+
+Ned noticed with satisfaction that the lid was properly locked.
+Jellup noticed it too. Without a word, he turned and easily found
+Ned's keys. Again he approached the crate, looking over the keys.
+
+"Jellup," exclaimed Ned in alarm, "there's gas in that box, and if
+you go near it with a light you'll blow us all up."
+
+"Gas, eh?" answered the eager Jellup. "Don't run no sich bluffs on
+me."
+
+"I warn you," cried Ned as the man approached the box, "it's taking
+your life in your hands."
+
+Something in the tone of Ned's voice must have alarmed Jellup, for
+he paused. Then he retreated a few steps and handed the almost
+burned out candle to the vigilant Domingo.
+
+"I allow I kin jest hev a look without no light to oblige you. I've
+been purty curious about this precious package ever since I see it.
+And ye'r a sight too anxious consarnin' my safety."
+
+What might really happen Ned did not exactly know. The gas
+generated from the liquid hydrogen was highly inflammable and
+explosive when confined. But the evaporation was exceedingly slow
+and the exhaust hose should easily carry the forming gas in safety
+to the air. But even a small accumulation might be in the partly
+depleted bulbs or the top of the crate and a fire would certainly
+ensue even if there was no violent explosion. And besides, just
+beneath the lid was their money--the cash Ned had secured for their
+further expenses and the return home.
+
+"We are anxious for all of us," explained Alan.
+
+"And mebbe anxious fur something else," sneered the marshal. "I
+reckon a peek in the dark ain't agoin' to hurt no one--an' it may
+help some."
+
+"Drop on your face, Alan," whispered Ned, "and lie flat."
+
+It was the only precaution they could take. Both felt that all
+their plans might end in a moment. But Ned could not resist
+watching--even though his face was close to the floor. He saw
+Jellup examine each key, guess the right one at once and then insert
+it in the lock. Yet, despite his assumed bravado, it was apparent
+that the man had considerable apprehension. For, before he turned
+the lock, he motioned to Domingo to retire further with the candle.
+
+Finally, as if summoning his courage, the avaricious marshal snapped
+the key, threw back the catches on each end of the crate and then
+slowly and gingerly and at arm's length began to lift the lid. With
+the top an inch ajar he paused, waited a moment or two, and then
+began sniffing as if searching for an odor.
+
+Ned saw him.
+
+"It doesn't smell," he explained quickly, "but it's there. Look
+out!"
+
+"Don't smell!" retorted Jellup. "Gas as don't smell? Well, that's
+agoin' some, I guess."
+
+Nevertheless, he had dropped the lid.
+
+But as quickly recovering himself he reached forward again and with
+a quick motion threw the top up and sprang back.
+
+To Ned's relief nothing happened. Either the light was too far away
+or the gas had all been removed by the hose. But this relief was
+quickly succeeded by another alarm. There had been no explosion,
+but their financial means were now at the mercy of two thieves, and
+he and his churn, bound and helpless, were powerless to protect
+either themselves or their funds. There was nothing to be done but
+to grin and bear it. For Ned's new leather money belt, containing
+six hundred dollars in gold was stretched out conspicuously and at
+full length on top of one of the two rows of glass bulbs in the
+case.
+
+"Lyin', as I thought," exclaimed Jellup. "Gimme' the light,
+Domingo." And the chuckle that followed almost instantly was
+indication enough that he had discovered the boys' small fortune.
+
+"Dangerous, eh!" he laughed. "Now, we'll see if the city gits its
+bond."
+
+Then he paused as if a thought had entered his head.
+
+"But, jest to keep the record clean, I reckon ye'd better give it to
+me yerself, young 'un. Jack Jellup ain't no burglar. Loosen him
+up, Domingo. And fur fear ye might need persuadin' jest take a peek
+at this," and he drew his revolver.
+
+When Ned had been liberated, Jellup pointed to the money belt.
+
+"Jest be good enough to hand me whatever's in that," he exclaimed,
+"without no hesitation. Then we'll have a little talk about what
+else is agoin' to happen."
+
+It was hard to surrender so easily but the risk of attacking two
+armed men single-handed was great. Ned walked slowly toward the
+crate.
+
+"Get busy," ordered Jellup; "we've got other business yit to talk
+of."
+
+Ned had a sudden impulse. The thing flashed on him and taking hold
+of the belt in the middle he lifted it until the two ends were just
+over an open-mouthed bulb of hydrogen, and then as if by accident
+dropped the belt into the jar. The clear, watery liquid splashed
+and the belt disappeared.
+
+"Water," shouted the eager Jellup, "Jist plain water." And as Ned
+sprang back the gold-fevered marshal sprang forward and plunged his
+hand into the liquid.
+
+He did not immediately know that his hand was in the depth of a
+liquid whose temperature was 423 degrees below zero. But the thin
+film of gas that instantly formed and protected his naked flesh
+dissipated in a moment and then one benumbing, paralyzing shock
+swept over Jack Jellup's body.
+
+With a cry wrung from him by pain such as few mortals have ever
+experienced and survived, the stricken man fell unconscious to the
+floor--his arm frozen as solid as crystallized steel.
+
+
+
+
+CHAPTER XVI
+
+READY TO "LET GO ALL"
+
+
+In the confusion that followed the sudden extinction of the candle,
+while Ned was freeing Alan and Jack Jellup was uttering heartrending
+groans, the marshal's confederate lost his nerve and made his
+escape. When a lantern had been procured, immediate attention was
+given to the stricken man.
+
+Ned hastened to secure a bucket of water. Wrapping the corner of a
+blanket about the handle of a tin dipper he ladled out a spoonful of
+the liquid hydrogen and, although the numbing chill ran through his
+fingers and up his arm, he managed to pour the hydrogen into the
+contents of the bucket.
+
+The pail of lukewarm water became almost instantly a cake of solid
+ice. As Ned dropped the tin dipper to the hard adobe floor it flew
+into a hundred pieces. The inconceivable cold had crystallized the
+metal until the slightest shock was sufficient to break it into
+pieces.
+
+At the sound of the crashing tin Ned instantly thought of the belt
+of gold yet in the hydrogen jar. But a human being was in pain, and
+he gave his first attention to the suffering marshal. He had made
+the ice to use in drawing the frost out of Jellup's frozen arm. In
+a few moments he had mashed a portion of the ice into small bits,
+and using a blanket to make a pack, he soon had Jellup's rigid arm
+encased in the fine ice. This he applied for the same reason that
+snow and ice water are applied to frozen ears and noses. But his
+treatment was of no avail.
+
+The rain was now falling steadily and it was dark, but Ned found
+that it was nearly day--a little after four o'clock. Jellup's
+suffering was so extreme that the boys had given him a hypodermic
+insertion of morphine, using their "snake-bite" outfit, and in a few
+minutes the man's ravings ceased and he quieted into a deep sleep.
+
+While awaiting this, attention was given the gold. Feeling free to
+approach the now open jars with a light it was seen that a portion
+of, the belt protruded above the liquid. A cord with a sailor slip
+knot was lowered over the extended bit of leather, drawn taut with a
+jerk and the belt was slowly lifted out. A folded blanket had been
+placed on the floor to receive it. As Ned expected, the leather
+crumbled and broke like glass as the belt fell on the soft blanket.
+
+"If you want change for a twenty-dollar gold piece just tap one of
+those with a stick." said Ned, laughing and pointing to the gold
+pieces scattered among the broken fragments of the belt.
+
+"Not I," exclaimed Alan, "not after what happened to the tin
+dipper."
+
+Leaving Alan to watch over the unconscious Jellup and the frozen
+gold, Ned dressed himself, and in spite of the rain hastened out in
+the just perceptible dawn to carry out a plan he and Alan had agreed
+upon. An hour later, with the assistance of Mayor Bradley, the
+marshal, now somewhat easier, was placed in a bed in his own home.
+Unless the silent Mexican told it no soul in all Clarkeville other
+than Mayor Bradley and the air ship boys knew why Jellup was absent
+from his haunts and his post of duty that day. Nor did many of them
+ever know, when Jellup reappeared on the streets after weeks of
+suffering, how he had been injured. They only knew that his right
+arm was gone and that he was no longer marshal.
+
+The rain ceased with the coming of the day.
+
+"If we don't get away pretty soon," suggested Alan, as Ned was
+getting into dry clothing preparatory to tackling another of Mrs.
+Buck's meals, "this thing will be getting on my nerves."
+
+"Well," answered Ned philosophically, "there is mighty little worth
+having in this world that isn't hard to get."
+
+If all went well that day the boys hoped to be ready to make their
+departure that night or the next morning. Therefore they went to
+work with a vim. Both felt more comfortable when, after finding
+that the gold coins had returned to their normal condition, they had
+again concealed them. The propeller, rudder and aeroplane guides
+were now put in place and tested.
+
+As the engine, with a speed of 1,400 revolutions but geared down to
+800, began to turn the shaft and the twelve-foot propeller began to
+revolve, Ned swung his hat in the air. Without a break the speed
+increased to 500, 600, and then 700 revolutions a minute.
+
+"Shut her off," exclaimed Alan joyously, as the white arms flew
+round and round and the air shot backwards on both sides of the long
+car. At 750 revolutions the car was rocking and lurching as if it
+would soar birdlike into the air. At 800 the powerful pulling
+propeller began to overcome the rigidity of the framework on which
+the car rested and as Alan caught and held the car, fearful that it
+was about to fly away under the propeller power alone, Ned shut off
+the engine.
+
+The next instant the two boys, with clasped hands, were doing an
+Indian war dance in their glee.
+
+It was not long until the rudder wires and the aeroplane shafts had
+been attached to their proper guide wheels in the lookout or pilot
+portion of the engine cabin. Then came the preparation of the
+balloon bag itself. Here again Ned showed what he had accomplished
+in the six weeks he had spent in the East.
+
+Clearing a space near the generating tanks, they placed the one
+hundred sand bags, weighing forty pounds each, in parallel rows.
+These sacks, with convenient loops on each for attaching the rigging
+of the bag as it was being filled, had already been prepared by the
+"greaser" laborers, but the placing of the two tons of dead weight
+was not a joke, and the boys regretted that they had not kept a few
+men around. But by noon this was done, and then the great
+waterproof fiber trunk containing the silk bag was rolled out
+between the retaining bags. The boys could not carry it, as the
+balloon itself weighed seven hundred and twenty pounds, but they
+improvised rollers and with many a laughing "yo he ho" finally
+accomplished the task.
+
+The bag had been made by one of the leading aeronautical engineers
+of America, whose factory, strangely enough, was in one of the small
+inland towns of New York State. In a spirit of humor the
+manufactory had been termed the "Balloon Farm," and so famous was it
+that Ned had even planned to spend a part of his summer vacation
+visiting it. When Major Honeywell gave him the opportunity, Ned was
+at once determined to utilize every advanced idea of the skilled
+owner, whatever the cost.
+
+The result was a machine-varnished and, as nearly as such a thing
+was possible, hydrogen gas-proof bag. In the construction of this
+the experienced manufacturer and engineer, who was no other than
+Professor Carl E. Meyers, the hero of hundreds of ascents, had used
+a new machine which applied simultaneously to both sides of the bag
+fabric several thin films of elastic varnish. The bag itself
+consisted of two layers of Japan silk between which was a layer of
+rubber, all being sewed together and then vulcanized.
+
+But the balloon trunk was not opened at once. The pipe to convey
+the gas from the cooler and purifying tank had been brought in
+four-foot lengths of light wood, cemented and shellacked. Eight
+lengths of these were laid to the center of the cleared place and
+then the joints were wound with binding cement tape. When these
+things had been satisfactorily adjusted it was mid-afternoon.
+Everything now seemed ready for the filling up of the generating
+tanks, the inflation, the flight, and "good-bye."
+
+Therefore, a final consultation was held. Wind tests conducted each
+day had shown the prevailing breezes favorable, or at least not
+against the aeronauts. The inflation would require approximately
+ten hours. If begun at once this would make the departure possible
+about midnight. This was not undesirable as the absence of the hot
+southwestern sun would make the gas easier to control. But another
+thing had to be taken into consideration. Only four days had
+elapsed since Elmer and Bob and Buck had started. Were they yet at
+the rendezvous?
+
+"I don't see what difference that makes," said Alan. "We expect to
+sail directly north and east of the foothills. If they have not
+reached their camp they must be nearly there and on the way. We've
+got to locate them with our glasses anyway. Let's start and pick
+them up where we find them."
+
+"True enough," answered Ned. "The way the engine is working, in
+this light favoring wind, we ought to make eighteen miles an hour
+anyway. If we leave at midnight, by five o'clock in the morning we
+can be ninety miles north. The only trouble is in the handling of
+the bag. It's going to take at least twenty men to move the
+inflated bag from the retaining weights to the car and we can't make
+the rigging fast in the dark. We'd better begin work at four
+o'clock to-morrow morning, as soon as it begins to be light, and get
+away about two in the afternoon. I think we'll see our friends
+about seven or just at dark, if we do."
+
+
+
+
+CHAPTER XVII
+
+AN INTERRUPTED FLIGHT
+
+
+And so it was arranged. The young aeronauts thus had all afternoon
+to store provisions, water, gasoline and the instruments. The
+altitude barometer, the recording thermometer, the statoscope and
+recording hygrometer, together with the telescopic camera were each
+given a place on the bridge and lashed to the netting. The
+twenty-five-foot rope-ladder, strong but light, that was to hang
+below the car, and the anchor and drag rope, were attached, the name
+pennant of white with the word "Cibola" resplendent in blue, "turquoise
+blue," explained Ned--was unfurled on its little staff just abaft the
+big propeller, and a new silk American flag was laid out it the stern
+of the car to be run up on its halyards as soon as the bag was attached.
+
+Then came the careful transfer of the liquid hydrogen. One at a
+time the cast iron eases were carried from the building, hoisted
+aboard the car and lashed in place. Before supper Ned had time to
+go to the depot and send a telegram to Major Honeywell, who was yet
+in Chicago. It read:
+
+"Ready for inflation. All O. K. Sail at 2 P. M. to-morrow, August
+11."
+
+He then visited "Saloon Row" and arranged for twenty men to report
+at four o'clock the next morning. No chances were to be taken that
+night. Dividing the hours up to four A. M. into two watches, the
+two boys had supper and Ned was soon fast asleep on the floor of the
+car "trying it out."
+
+At the first blush of dawn the corral gates were thrown open and in
+a short time all the men engaged reported. Some of them were put to
+work dumping the heavy iron filings into the big oak gas generators
+and Ned and Alan began the delicate work of laying out the bag,
+bottom side up the thin silken folds of the golden shell were slowly
+lifted and laid on the ground. When the bottom filling valve had
+been attached to the wooden gas conduits the mammoth sections of the
+long gas receptacle were stretched out on top and then carefully
+smoothed until an even inflation was assured.
+
+This done, the rigging trunk was opened and the seine-like mass of
+delicate hemp cords laid over the bag. No "greasers" were permitted
+to assist in this. Ned and Alan, in bare feet, laboriously but
+carefully drew the silk folds of the bag into the net. When this
+was completed the suspension cords reached out in all directions
+like skeleton fingers. In a quarter of an hour these had been
+attached to the retaining bags with slip knots and then the boys
+were surprised to find that it was already after six o'clock. At
+their best they could not now hope to reach the relief camp before
+nine o'clock and after dark.
+
+Mrs. Buck came with a huge pot of coffee for all, and then followed
+the last step. One by one, borne on the shoulders of the curious
+workmen, the dangerous carboys of sulphuric acid were emptied into
+the generating tanks. The boys guided each step of the men,
+explaining the danger, and the work was finally completed without
+hitch or accident.
+
+At the first bubble of gas the boys felt like doing another war
+dance. But they were "business men" now and had to put on dignity
+in the face of their employees. In two hours the reaction of the
+bubbling acid had sent enough hydrogen through the purifier to raise
+the bag shoulder-high and everything was going splendidly. The boys
+had removed their working clothes and were now in the light but warm
+canvas suits and caps they meant to wear in their flight.
+
+Ned stole away a few minutes and at the bank secured bills to pay
+off the men. On his way back he stopped to invite Mayor Bradley to
+lunch with them on the Cibola and to be present at the "let go." By
+noon the men had been paid and the articles of baggage and tools
+that were to be left behind had been packed, tagged with shipping
+directions and turned over to Buck's wife.
+
+The cigar-like bag, 98.4 feet long and 17.4 feet in diameter, which
+was to hold over 65,000 feet of gas, was now so far inflated that it
+was nearly off the ground. Then Mayor Bradley came. With pride the
+boys bade him climb into the cabin of the Cibola.
+
+"You won't find anything hot in a balloon, Mr. Mayor," laughed Ned,
+"except the reception. Make yourself at home."
+
+On the bridge of the craft the two boys and their guest had
+luncheon. Cold potted chicken and baked beans served on wooden
+plates with hardtack and water, and sweet chocolate for dessert, was
+the simple meal, but it tasted like a feast.
+
+"Have you christened the craft yet?" finally asked the Mayor who had
+absorbed some of the enthusiasm of the young aeronauts.
+
+"That's for you to do," politely answered Ned.
+
+The luncheon was hurried to a finish, for the boys could see that
+the bag needed final attention. It had risen higher and higher and
+was now swaying and tugging at the suspension ropes. Both boys
+alighted and at once began straightening the extension ropes. Here
+and there where the cordage net was out of place they pulled down
+the bag and adjusted the rigging. Finally a little after three
+o'clock, the great case had filled out until its smooth glistening
+sides resembled the skin of a fat sausage.
+
+"All ready!" ordered Ned as he shut of the valve of the cooling and
+purifying box. "Now, every man bear a hand."
+
+One at a time the extension cords were untied from the retaining
+bags, and each of the workmen was given four of the light but strong
+lines. The Mayor himself passed among the men with stern
+injunctions to hold fast. As the last cord was loosed the great
+tugging bag was held wholly by the scared men. Then, with slow and
+measured steps, the double line of assistants advanced to the car
+and along each side of it.
+
+"All steady," commanded Ned when each man had been placed; "now hang
+onto her."
+
+Then he and Alan, springing into the car, began the work of making
+it fast to the bag. There was a place marked for each of the
+extension ropes, and the air ship builders, beginning at each end of
+the car, carefully adjusted and tied the end of each rope to the
+frame of the ship. As the cords were taken from the attendants the
+men took hold of the lower framework of the car, and to make doubly
+sure each man was cautioned to throw his entire weight into the
+work.
+
+At last the final rope was made fast, and three thousand pounds of
+human flesh and muscle were holding the tugging balloon. Ned,
+covered with perspiration, and nervous but happy, was hastily
+connecting the compensating balloon tube with the hand blower on the
+bridge, and Alan had run astern to tie the new national colors to
+the halyards swinging from the end of the bag.
+
+"Hold on," cried Ned seeing that Alan was ready to run up the stars
+and stripes. "Just a moment. Are you all ready, Mr. Mayor?"
+
+"All ready," came the answer from the town official, as he stood on
+a box, his hat off and a revolver in his hand.
+
+"With a western salute I christen this balloon the 'Cibola,'" he
+exclaimed, and a shot punctuated his speech. "Good luck and
+goodbye!"
+
+As the shot sounded Alan's flag ran fluttering upwards. Ned's eyes
+took one final look fore and aft and then he leaned over the car for
+the last words for which all were waiting.
+
+They were on his lips and the eyes of twenty straining men were
+fixed on him to hear the command, "Let go." One nervous attendant,
+apparently thinking the order had been given, threw up his arms with
+a shout.
+
+At that instant there was a second sharp pistol shot, and a quick
+cry from the street outside the corral.
+
+"Hold on there, all of you!" shouted Ned. His dream had rushed back
+to him with a sickening chill. Had some one shot at the towering
+bag? "Hold on!" he yelled.
+
+At that moment there was another shout and Bob Russell, his face red
+with the sun and his shirt wet with perspiration, walked into the
+corral. In his right hand was gripped a revolver and in his left a
+repeating rifle. In front of him, and prodded on by Bob's pistol,
+was the Mexican, Domingo, Jack Jellup's tool and fellow thief.
+
+
+
+
+CHAPTER XVIII
+
+FREE AND AFLOAT AT LAST
+
+
+This is what had happened.
+
+At the time of the rain storm, two days before, Buck and his
+cavalcade were in camp on the bank of the dry Chusco, sixty miles
+north of Clarkeville. The experienced scout knew that a water
+supply was now assured, and he at once followed prearranged orders
+by instructing Bob to return with the smaller wagon. This was a sad
+blow to the young reporter, but it was a part of his contract and he
+knew that it was his duty to obey. And with necessity before him,
+he acted promptly. Emptying the heavy casks, Bob started on the
+back trail at five the following morning, and by night had made
+thirty miles with the light wagon. All day he wondered if it might
+not be possible to reach Clarkeville again before the Cibola sailed.
+
+The next morning, spurred on by the hope that he might do this, he
+started at daybreak. By the middle of the morning he was on the old
+wagon trail and making better time. Some time after two o'clock he
+came up over the rise of the last foothills and saw, eight miles
+away, the glistening shape which he at once knew was the inflated
+balloon. He hesitated a moment and then, unhitching the horses,
+mounted one bareback and began a dash for the town. The animals
+were tired and worn, and progress was slow, but it beat walking, and
+Bob urged them on.
+
+As the young reporter came nearer and the balloon grew more distinct
+he knew that it would be a close call. From time to time as the
+winded horses dropped into a walk Bob wondered why he was making
+such a race. "I can't go with them," he argued. But, like the
+trained reporter, be decided that no effort was wasted that gave him
+new information. And it was something out of the ordinary to see
+the most complete balloon ever made start on a mysterious flight
+into the wilderness.
+
+So he spurred up the horses anew. The hot sun reflected from the
+yellow sands burnt his face and his muscles were sore, but he stuck
+to it. When half a mile from the town he could see the boys on the
+bridge of the Cibola. When a quarter of a mile away he decided that
+he could beat the horses by going afoot, and, throwing himself to
+the ground, he ran onward, knowing that the tired animals would
+follow. Out of breath he reached the edge of the town and stumbled
+on toward the corral.
+
+With head down he plunged forward. Almost at his goal he threw his
+head up for breath just in time to notice a kneeling man with a
+rifle at his shoulder.
+
+"Hey!" yelled Bob with what breath he had.
+
+Then he saw that the man was aiming directly at the balloon swaying
+above the nearby corral fence. He also recognized the man instantly
+as one of the sullen court spectators, and Jellup's crony. The
+rifleman dropped the muzzle of his gun and turned.
+
+"I guess I am something of a gun man," explained Bob later to the
+boys, "for I had that new revolver of mine on the 'greaser' before I
+knew what I was doing myself. I didn't even then realize what he
+was about to do. But I had the drop on him and when I figured out
+that he meant to put a hole in the balloon, why, I just had him
+right. And here he is."
+
+Alan looked at Ned. Both boys were puzzled. A few moment's talk
+with Russell explained the whole situation. The balloon was ready
+and the relief expedition was undoubtedly now in camp awaiting them.
+It needed only the words and they would be off with the inquisitive
+reporter left safely behind. And yet the word did not come. Ned
+and Alan stood looking at Bob, and the reporter gazed in turn at the
+beautiful straining car. Bob's face was a study. He had now made
+some return to Ned for possibly saving his own life, but none of the
+boys was thinking of that. In Bob's fine young face was the longing
+of a child. In Ned's and Alan's faces were the traces of boyish
+sympathy.
+
+The young aeronauts were very close to each other and all were
+silent. Then Alan turned slowly to Ned and with a little quaver in
+his voice whispered, "Shall we?"
+
+Ned made no answer. A smile lit up his face and he sprang down the
+little ladder into the engine cabin followed by his chum. Almost
+instantly the trap door in the floor of the car dropped down. A
+moment later three fifty-pound sacks of ballast tumbled through the
+door to the ground beneath. The bag tugged and strained as Ned
+reappeared above.
+
+"Hurry up, Bob, if you're going with us," he said quietly, leaning
+over the net of the bridge, "and close the door as you come up."
+
+Bob hesitated, as if he had not heard aright, but then he
+understood, and with tears in his eyes be sprang forward. There was
+a jar and Ned knew the new passenger was aboard.
+
+"All ready?" he called sharply from the bridge.
+
+"Aye, aye, captain," came in a choking but jubilant voice from the
+inside of the cabin.
+
+"Stand by, everybody," sharply ordered Ned. And then, as Bob's
+shoulders appeared through the hatchway, the commander of the air
+ship gave a final look about.
+
+"Let go all," he cried sharply. "Everybody!"
+
+For a moment only one clinging workman careened the buoyant craft
+and then, straight up, the Cibola bounded like a rubber ball.
+
+"Good-bye, all," came from Ned, cap in hand, as he leaned from the
+bridge.
+
+There were cheers from below and the Cibola was at last free and
+afloat.
+
+"Sit down here and keep quiet," sharply ordered Ned as Bob crawled
+out on deck. Then the commander of the balloon disappeared below.
+
+There were almost immediately several sharp, muffled explosions, and
+then the white propeller began to turn. The balloon was drifting
+quickly toward the northwest and rising--Bob could see its shadow
+following on the sandy plain. Then the arms of the propeller turned
+faster and faster and a velvet whirr in the cabin showed that the
+engine was falling to work. As the propeller blades settled into a
+steady hum the vibration of the car indicated increased speed. This
+Bob could also detect from the more swiftly flying shadow.
+
+The shadow was also growing smaller, and this meant that the Cibola
+was still ascending. Now the shadow paused and turned. Alan had
+thrown the rudder over and the balloon had responded instantly. The
+aeroplane arms stretched out horizontally on each side of the car.
+Ned, reappearing, took a quick look at the altitude gauge and again
+disappeared. The aeroplane arms dipped in front almost forty-five
+degrees and the current, blown back by the propeller, struck them
+with a jar. The craft again responded and slowly took a downward
+slant.
+
+Propeller, rudder and aeroplane being at work, Ned again appeared.
+
+"Go below," he ordered sharply, "and bear a hand when needed."
+
+Bob did so. Alan was on the pilot platform with his hands on the
+wheel controlling the rudder wires. His eyes were fixed straight
+ahead.
+
+"See that lever," he said, jerking his head to the left.
+
+Bob quickly discovered the aeroplane guider control and sprang to
+it.
+
+"Wait for orders," added Alan.
+
+
+
+
+CHAPTER XIX
+
+THE FIRST FLIGHT
+
+
+The balloon was still sliding downwards and swiftly forward. For
+several minutes the three boys stood in silence. Only the steady
+whirr of the engine and a musical humming of vibrating wires could
+be heard. Bob wondered if they were headed earthward again, for he
+could see the approaching foothills widening out beneath. At last,
+when they could not have been over five hundred feet from the
+ground, came the quick order:
+
+"Right the planes."
+
+Bob was almost caught napping, for he was busy looking through the
+window. But his hands responded instantly, and he almost choked
+with chagrin to find that he had started to throw the lever the
+wrong way. But his recovery of himself was instant and with a
+desperate pull he forced the guiding planes back horizontally. The
+glide downward stopped and the Cibola shot forward with renewed
+speed.
+
+On the bridge Ned held a fluttering chart before him.
+
+"How is she heading?" he called to Pilot Alan at the wheel. With a
+glance at the compass before him Alan promptly responded:
+
+"Nor'nor'east."
+
+"Make it north by east."
+
+A quick slight movement and a strain told that the alteration had
+been made.
+
+"North by east it is," sang out Alan.
+
+"Keep her there," was the echoing response.
+
+Bob was thrilled. Every word was to him a joy. Everything had
+happened so quickly that he hardly knew what it all meant, but he
+was happy. Even the sudden discipline pleased him and he was glad
+to be a part of it. The knowledge that a younger boy was giving him
+orders did not bother him. He had skill in his own line, but he saw
+and realized that in the Cibola Ned Napier was in charge and meant
+business.
+
+For some time then no word was heard. The Cibola, speeding, swiftly
+onward, had crossed the low foothills and was pulling herself
+through the almost breezeless air like a modern liner, five hundred
+feet above the ground. She was holding her course beautifully.
+Then Ned appeared and tested the gas exhaust and oil feed of the
+engine.
+
+"Were you ever in a balloon before?" he said when he had finished,
+turning sharply towards Bob.
+
+"Never," answered Bob, glad enough for a chance to say something.
+
+"Have you any matches?" somewhat sternly asked the commander of the
+Cibola.
+
+"Sure," replied Bob reaching in his pocket and finding one.
+
+"Any more? All of them."
+
+Surprised, Bob searched his clothes and discovered a few more which
+he obediently handed over to his superior officer. Noting the look
+of surprise in the reporter's face Ned laughed.
+
+"The first rule in a balloon is 'No fire.' But beginners forget,
+sometimes; we can't take this chance with you."
+
+"Take anything I have got," answered Bob with his old smile, which
+had now been in eclipse for some time, "and if I can speak at last I
+want to say that you boys are white, clean white, through and
+through. Didn't you need that ballast?"
+
+"We may need it badly," said Ned, laughing. "If it should become
+necessary I suppose you won't mind if we throw you overboard."
+
+"No," retorted Bob, "not if it is a little at, a time. But you're
+bricks--both of you--if I thank you I'll cry." The tears were again
+in his eyes.
+
+"Well, it wasn't the thing to do, I suppose," said Ned turning away,
+"but you looked so hungry to go, and I knew what it meant. So I
+thought we'd just give you a little ride up to the camp."
+
+"Yes, of course," answered Bob slowly as his hopes fell. "Put me
+out wherever you like," he added.
+
+"You can go up now and have a look around," said Ned at last, "both
+of you. I'll take the wheel."
+
+The relieved boys scrambled onto the bridge deck. Night was coming
+on and the mountains to the west were already black. Evening
+shadows were lengthening on the sloping plains beneath and a gentle,
+rising breeze flapped the flag and pennant and swayed the bag above
+them. Beneath, the Chusco wound its half dry course and off to the
+east a blue haze, melting into the unending sand, told of a treeless
+and waterless waste.
+
+"And there," exclaimed Alan at last, pointing off to the northwest
+where snow-capped, ragged peaks rose out of a black jumble of
+mountains, "are the Tunit Chas and the land of our dreams.
+To-morrow--"
+
+"One moment," interrupted Bob quickly. "I think you are forgetting.
+That is your secret and not mine."
+
+Alan flushed. "I forgot," he said with a stammer, "and I thank
+you."
+
+"I can't afford to make you sorry you brought me," added Bob, "and
+you are not going to be."
+
+There was a little jar. The propeller slackened a trifle, and Alan
+explained that Ned had headed the Cibola another point into the
+freshening breeze.
+
+"Steward," said Ned from below, "it's seven o'clock and I'm hungry.
+Besides, it's getting pretty dark down here."
+
+Alan and Bob looked at each other and laughed.
+
+"That certainly means me," exclaimed Bob, and both boys clambered
+below. With Alan's help Bob made his first examination of the store
+room.
+
+The meal was rather haphazard, as the boys, carried away by the
+excitement of their new flight, had neglected to eat when it was
+light. But water and hardtack were easily accessible, and Alan,
+taking the first two cans at hand, found happily that they contained
+sardines and veal loaf.
+
+"We'll eat on deck," suggested Ned, as he set the wheel and had
+another look at the engine, which had not missed a revolution.
+
+The night that greeted them was magnificent. The moon was not yet
+up, but the stars were scintillating in the inky sky and the deep
+silence of the clouds and desert was about them. Bob gazed as if
+spellbound. The charm of the night appealed to him as it did to Ned
+and Alan; but with it his brain formed phrases--"cloudland by
+night," "a dash to the stars." The reporter in him was thinking
+"copy."
+
+"Hey, there, wake up!" cried practical Ned.
+
+Bob flew to his task; with a turn he had the veal loaf can open and
+had dumped its contents in the wooden plate held by Alan.
+
+In another moment he would have thrown the empty can overboard but
+the watchful Ned, ready for another lesson in aeronautics, caught
+his hand.
+
+"Don't you like the route we are taking?" laughed Ned.
+
+Bob's face showed he did not understand.
+
+"The loss of the weight of that can might send us sparing upward a
+thousand feet," explained Ned dryly, "so don't cast over ballast
+until you get orders."
+
+Bob shook his head. "Well doesn't that beat all," he exclaimed.
+
+As night fell and the air grew heavier, the barometer showed that
+the Cibola had a tendency to rise. The aeroplanes were readjusted
+and then for an hour the craft sped on untouched. At eight o'clock
+Ned said:
+
+"We haven't traveled over eighteen miles in an hour and we've been
+afloat four hours. If we are still over the Chusco and Elmer and
+Buck are at the appointed place we may be within ten or twelve miles
+of them."
+
+"They are going to burn three small camp fires set in a triangle,
+you remember," remarked Bob.
+
+"Therefore," suggested. Ned, "all keep a sharp lookout."
+
+At half past eight Ned showed some concern. No lights had been
+sighted and the reckoning showed that they must be within two or
+three miles of the probable location of the camp. Another fifteen
+minutes went by, and yet no signal fires were seen. They had now
+passed over the junction of the two rivers, if their calculations
+were right, and Ned and Alan were in a quandary.
+
+"It's no use to go on," commented Ned; "so we'll just make a wide
+circle and see what we can find."
+
+It was also useless to look below. In the darkness there was no
+sight of either river or desert.
+
+"It we don't pick them up in that way," continued Ned, "we'll
+descend and tie up for the night."
+
+Both Ned and Alan went below, and with the engine shut down to half
+speed the Cibola was turned on her course in a wide sweep. Bob
+alone watched with anxious eyes, until he was joined in a short time
+by Ned. There was no sound but the soft chug-chug of the engine,
+and for some time neither spoke. The breeze of the early evening
+had died and there was not a breath of air. Alan in the dark cabin
+below held the wheel and Ned and Bob alone, hanging over the side
+net, watched and listened in vain.
+
+
+
+
+CHAPTER XX
+
+FIGHTING INDIANS WITH A SEARCHLIGHT
+
+
+"Stop her!" It was Ned's voice in quick command. The young
+aeronaut, peering over the side of the car of the Cibola into the
+black night, had suddenly seen something that prompted the order.
+It was a distant flash of light. This was followed by an echoing
+explosion. The other boys heard the explosion and all instantly
+knew that it was a shot from a firearm. Almost before Alan could
+shut off the power Ned had disappeared into the cabin to help head
+the balloon in the direction of the spurt of fire. The Cibola
+slackened speed and they waited, drifting slowly toward the east.
+Then, suddenly, and almost together came two streaks of fire and two
+more explosions.
+
+"One of them might mean a signal," said Ned gravely, "but they were
+not from the same spot. If it were Elmer he would have the three
+fires. If it is Elmer and Buck and they can't make a fire and are
+shooting I am afraid it means trouble."
+
+"It may mean Indians," suggested Bob, "and they may have put out
+their fires for safety."
+
+"They might even be holding off an attack of some kind," added Alan
+anxiously.
+
+Just then there was another crack of a firearm now a little nearer.
+The Cibola was drifting directly toward the sound, but very slowly,
+and would soon have lost all headway.
+
+"I don't want to be presumptuous," said Bob in a low voice, "but
+can't we land and find out what the trouble is?"
+
+"We can find out without landing," replied Alan.
+
+It was so dark in the cabin that the boys could only dimly see each
+other, but Ned was groping about near the silent engine. In a
+moment he had secured from the ammunition case a storage electric
+light, and cautiously shading the lens with his cap he asked Bob to
+hold it. Then he turned to his chum.
+
+"I didn't know just how we would use our little drop light," he
+began; "but it seems that the idea wasn't half bad. There is a
+tribe of Indians not far from here that would steal a horse or cut a
+man's throat quickly enough--the renegade or Southern Utes." As he
+spoke he was digging in a chest extracting various small parcels.
+"Not even the other Indians have any use for the Utes. And there is
+only one thing to do. We must first find out if our friends are
+below."
+
+With the help of the flashlight Bob could we that Ned held in his
+hand a large, high candle-power incandescent bulb and was adjusting
+it in a silver reflector.
+
+"With an electric light?" exclaimed Bob.
+
+"Why not?" replied Ned. "And the help of our little dynamo."
+
+Ned took the flashlight, held it under his coat, and crawled around
+in front of the silent engine. "It's here," he explained for Bob's
+benefit, "and I am just throwing the gear onto the propeller shaft."
+
+"Well, if you are afraid to show this little light why aren't you
+afraid to show a brighter light?" asked the observing reporter.
+
+Alan answered him.
+
+"We are only afraid because it might draw an attack from some
+observer. Balloonists are never safe from meddlesome persons or
+worse. But there isn't the same danger if the light isn't on the
+balloon."
+
+"Sure," said Bob. "I understand that. But you can't hold it very
+far away."
+
+"No," answered Ned, "that's why we braided two good copper wires in
+our drag rope." As he said this he opened the trap door in the
+floor of the cabin and feeling about in the dark soon had hold of
+the coiled drag.
+
+"I guess I'm dull," began Bob.
+
+"No," interrupted Alan, "only you haven't given two or three years
+to figuring out the possibilities of an air ship."
+
+Ned was attaching the bulb, reflector down, to the end of the rope.
+
+"That rope is three hundred feet long. A light at the end of it is
+quite a way from our bag.
+
+"Oh, I see," exclaimed Bob at last. "If we find Indians and they
+shoot at our searchlight they are pretty sure to miss us."
+
+"That is the theory," answered Ned.
+
+And then the plan in Ned's mind was explained. The engine was to be
+started at quarter speed, which meant that the sound would be
+imperceptible; and, lying on the floor of the cabin, Ned was to
+direct the movements of the ship, with Alan at the rudder wheel and
+Bob at the aeroplane guider.
+
+"A quarter to ten o'clock," said Ned glancing at his watch as he
+shut off the concealed flashlight, "and now start her up."
+
+As Alan started the engine and it began to turn the propeller they
+could tell by the light breeze that the car was moving again, but
+very slowly. The other boys could also hear Ned delicately paying
+out the long drag rope. At last it was all out. Then Ned crawled
+forward again to the dynamo and up to the partly open floor of the
+car and whispered that he was ready. The multiple gear was already
+speeding the little generator swiftly.
+
+"Lie down on the floor and watch," murmured Ned softly, "I'm going
+to turn her on."
+
+Alan and Bob did so. As their two heads filled the open trap in the
+cabin floor there was a click and then, as if some necromancy had
+focused the sun on a part of the darkened world, a circle of light
+seemed to spring out of the desert beneath. Yellow, with here and
+there a ragged rock and a sage brush or two, the shadows of the
+rocks and brush black like spilled ink, and the sand glaring back at
+them with almost quivering brightness, the circle shot back and
+forth as the light followed the swinging rope. But no living thing
+was in sight. A click and all was black again.
+
+"Nothing doing," exclaimed Bob.
+
+"Wait," suggested Ned, "persons we couldn't see may have seen them."
+
+Almost as he spoke there was another quick report.
+
+"Did you see the flash, Alan?" asked Ned eagerly, for he had been
+busy with the dynamo.
+
+But Alan was already at the wheel, and again the car swung from its
+course.
+
+"Wait," he exclaimed, "turn it on again when I give the word."
+
+After perhaps two minutes he gave the signal and again Ned flashed
+the gleaming bulb. Again the circle sprang apparently out of the
+black ground. As the car drifted forward the black blotched golden
+sand ran the opposite way like a whirling panorama. A coyote
+sprang, dazed, from a clump of bushes and back again, but that was
+all.
+
+"Give him another chance," whispered Alan, and the light flashed
+out.
+
+"Listen," exclaimed Bob breathlessly, "wasn't that a cry?"
+
+Another moment and the sound came again.
+
+"Elmer!" exclaimed the two air ship boys together.
+
+The Cibola swung instantly at Alan's quick touch. Again the light
+flashed. Sand and rock and brush. The brilliant circle of light
+shot here and there, but the anxious watchers saw sign of neither
+friend nor foe. Then like a flash the level plain dropped into the
+sudden slope of a coulee and the darker shadow of water blotted out
+the glare of sand.
+
+"The river," whispered Ned. "Now watch sharp."
+
+As the light was blotted out this time Alan swung the wheel again.
+He knew instantly that they were on the wrong track, as they were
+going east and crossing the Chusco. Elmer and Buck would not cross
+the river. The camp was to be on the west side.
+
+"Follow the river," ordered Ned quickly; "the west shore."
+
+In order that the Cibola might be laid on the new course Ned threw
+on the light switch again. As he did so and the light flashed there
+was the sharp crack of a rifle and the light was gone.
+
+"Turn her on," exclaimed Alan; "I want to get a line on the river
+bed."
+
+Ned laughed. "I'll need a new bulb first. Some one down below
+turned it off."
+
+"What?" exclaimed the other boys together.
+
+"Shot out," calmly retorted Ned.
+
+
+
+
+CHAPTER XXI
+
+A CORDITE BOMB AND ITS WORK
+
+
+In a moment the boys were hauling in the rope and Ned was back in
+the cabin after a new bulb which he secured and attached in the
+dark.
+
+"Now give her a swing," he said as Bob again lowered the rope. "It
+will make it harder to hit."
+
+When Bob announced that all the rope was paid out Ned snapped the
+switch again. In spite of the gravity of the situation all the boys
+were tempted to laugh. A brilliant green glow shot down. An
+emerald circle of light flooded the ground beneath.
+
+"If anyone sees that they'll sure think it's a drug store,"
+suggested Bob.
+
+"'Or a sign of the Great Spirit, perhaps," added Ned soberly, "it
+may help us in more ways than one, if Indians are--"
+
+"Look," hoarsely shouted Alan, "there, over there!"
+
+But his words were superfluous. The three boys saw the same thing.
+And then as the wide swaying of the bulb swept the gnome-like
+picture in green from view Ned threw himself over and shut off the
+engine.
+
+Not a hundred feet beneath the brilliant bulb the precipitous bank
+of the river had again shot into the circle of light. At the very
+edge of the cliff stood the big freight wagon. Behind it, between
+the wagon and the steep river bank, stood two horses. At one end
+two more lay prostrate on the ground. In front a light barrier of
+boxes and barrels rose a few feet from the ground. And there, a
+rifle at his shoulder, knelt Elmer Grissom, their friend and
+servant. Buck was nowhere in sight.
+
+Their worst fears were realized.
+
+As the dramatic picture flashed from view each boy knew that it was
+time to act.
+
+"What's to be done?" exclaimed Alan, his voice choking.
+
+"There can't be many of them," answered Ned finally, as if thinking,
+"or they would pushed their attack. If we could locate them the
+rest would be easy. Let Bob take the wheel and try to get over the
+wagon again; I have an idea."
+
+The Cibola again answered the rudder and circled, Ned flashing the
+bulb until the river came beneath them. This required but a few
+moments, but, before the craft had gathered momentum on the way
+back, there were four shots almost together about three hundred
+yards to the right of where they supposed the wagon stood, and a
+quick reply from the river bank.
+
+"Our light did it," exclaimed Alan, "they are rushing the
+barricade."
+
+"Indians don't rush together, if it is Indians," replied Ned. "Keep
+on up the bank, Bob. It's risky for Elmer," he added with a husky
+voice, "but we've got to take chances."
+
+Again the light flashed. Ned and Alan hurried to the bridge.
+
+Within its circle and almost together, sealing the seamed and hard
+bank of the river, were five dark figures. As the powerful light
+encircled them the crouching figures sprang backwards. But they
+were not quicker than the alert and prepared Ned Napier. A small
+round object shot downward from his hands. The glare of flame as
+the missile struck true and the thunderous roar that hurled the big
+bag of the Cibola sideways told that the cordite bomb had done its
+work well.
+
+Bob was speechless. Ned and Alan were already in hurried
+consultation. They could not count on fortunately finding the other
+besiegers all together, "'and there are at least four more," said
+Ned. The rescue of the lone besieged lad was not an easy problem.
+The boys believed themselves now just above the wagon again, but
+they were afraid to draw possible fire to the barricade by showing
+another light.
+
+The hurling of the bomb overboard had shot the Cibola heavenward
+like a bird. Before they realized it the aeronauts had mounted up
+at least two thousand feet. They then began maneuvering to regain
+their position. But this was not so easy. A flash of the suspended
+searchlight gave them not a trace of their bearings and it was
+plainly apparent they would have to use time and patience in
+recovering the location of the besieged wagon. Using their best
+judgment, they put the aeroplanes to work, and, circling slowly, the
+Cibola gradually came nearer and nearer to the ground. After ten
+minutes or more the car gave a sharp bound upward.
+
+"The drag has touched the ground," exclaimed Ned.
+
+The aeroplanes were righted, the engine was stopped, and again the
+balloon was drifting. There was not a sound to guide the aeronauts.
+The contact with the ground had broken the bulb and it was not
+replaced. For aught the rescuers knew they might be again directly
+over the wagon. Not a shot had been fired since the roar of the
+explosion, but there was no reason to believe that the yet living
+besiegers had withdrawn.
+
+"More likely planning a final attack," suggested Alan.
+
+Again a council was held.
+
+"We've got to take the risk," said Ned at last in desperation; "we
+can't do anything up here."
+
+And then, with Alan's approval, the propeller was set turning again,
+but so slowly that the big balloon was just moving under control.
+The aeroplanes were also set to bring the craft nearer the ground
+and, as a precaution, Bob was sent onto the bridge with an open
+knife to cut away ballast if sudden ascent were needed. The drag
+rope had been brought in. There were no means of knowing how near
+the car might be to the earth and the suspense was decidedly trying.
+
+"I guess I can come a little nearer finding out," exclaimed Ned
+finally to the others in a whisper.
+
+Alan did not know what he meant, but he resumed his place at the
+wheel. Ned had disappeared in the dark.
+
+"Where are you, Ned?" asked Alan anxiously at last.
+
+The answer came from beneath the car.
+
+"Only down here, but I'm going lower," Ned replied, again in a
+whisper. "Be ready with that ballast."
+
+A perspiration of fear broke out on Alan's body. He sprang to the
+open trap door.
+
+Just discernible in the darkness was Ned's slowly retreating form.
+
+He was climbing down the twenty-five-foot rope landing ladder with
+only his own strong grip and the spruce rungs to save him from
+death.
+
+There was nothing to be said or done. Bob did not know what was
+going on below, but he knew that he had a task set for him, and in
+the long silence that followed while the Cibola settled lower and
+lower and drifted on and on in the dark he stood, knife in hand, at
+the ballast bags.
+
+
+
+
+CHAPTER XXII
+
+A THRILLING RESCUE IN MID-AIR
+
+
+Buck, the guide, and Elmer Grissom had reached their appointed
+rendezvous at two o'clock that afternoon. The hot journey had been
+tedious and uneventful. Only at the half-breed settlement twenty
+miles north of Clarkeville had they seen a human being. Therefore,
+after they had been in camp about an hour, even the vigilant,
+experienced Buck was startled to observe suddenly a solitary
+Indian--his horse as statuesque as himself--watching them from a
+knoll some two hundred yards distant.
+
+As the old scout raised both hands in signal of peace the Indian
+rode forward. The man was not in the Indian panoply of the old
+days, except that he wore moccasins and had two bands of red and
+yellow paint on his broad, dark face. A black wide-brimmed hat, a
+faded blue shirt and trousers completed his outfit.
+
+"How?" exclaimed the Indian.
+
+"Navajo?" answered Buck.
+
+"Ute!" came the answer. "Where go?"
+
+"Right here," said Buck good-naturedly, pointing to the ground.
+
+"Ute land!" retorted the Indian without a trace of expression in his
+face.
+
+"No," retorted Buck sharply, "not Ute land. Ute land there,"
+pointing north, "in Colorado."
+
+"Ute land!" exclaimed the red man again, this time scowling.
+
+Buck only shook his head.
+
+Then the Indian suddenly threw himself from his horse, strode to the
+wagon and threw up the tail curtain. Safely stored therein he saw
+the protected tins of gasoline.
+
+"Whisky?" he exclaimed.
+
+"No," laughed Elmer, "not whisky."
+
+"Whisky," repeated the stranger turning towards Buck; "drink!"
+
+But Buck shook his head.
+
+With out another word the Ute walked haughtily to his horse, threw
+himself upon it, and, clasping his heels to its sides, rode quickly
+away.
+
+"I'm sorry," exclaimed the veteran at last.
+
+"I had no idea that there were Utes around here."'
+
+"He doesn't seem dangerous," commented Elmer.
+
+"No," answered Buck, "men who'd cut your throat for a horse never
+do. The chances are he isn't alone."
+
+Elmer looked up in surprise.
+
+"We'll just make sure," exclaimed Buck, making as light of the
+affair as possible. "I don't want to lose my horses and you don't
+want to lose your freight. We'll make ourselves ready in case our
+friends come back to make us a little visit."
+
+And as night came on and Elmer helped Buck draw the wagon close to
+the river bank, where approach from the rear would be difficult, the
+boy began to realize what it meant to get away from the telegraph
+and policemen and law and order. And when the experienced scout
+unloaded a portion of their heavier freight and began to build a
+small barrier Elmer's usual joviality cooled into silence. The
+three piles of brush and driftwood from the river were laid out some
+distance in front of the camp in preparation for the agreed signal
+fires and then, before the sun went down, the scout and his
+companion made their camp fire and had supper.
+
+"What do yo' expec' deyll do?" asked the colored lad at last.
+
+"Well, you can't tell. Injuns are puzzles. When they steal they
+steal in the dark. When they fight they fight at daybreak."
+
+"What do yo' suggest?"
+
+"To tell the truth, son," answered Buck, "there ain't much to do but
+keep yer eyes open and pop it to the first red horse thief ye see
+crawlin' around in the night."
+
+"Hadn't we better light our signal fires?" asked Elmer.
+
+"There won't be any signal fires to-night," replied Buck, slowly,
+"if you want my advice. It's one thing for a bluffin' Ute to walk
+up in the daylight when you've got a fair chance to give him as good
+as he sends, and its another thing for him to get a bead on you a
+sittin' in the light o' yer camp fire--him in the dark."
+
+Elmer saw and understood.
+
+So night fell in silence with Buck and Elmer keyed up and ready to
+meet any possible attack.
+
+Nothing happened until several hours had passed. Neither Elmer nor
+Buck were any the less alert, however. The old scout was pacing up
+and down in front of the barricade and perhaps a hundred feet from
+it. Elmer could just hear his soft footfalls in the sand. Suddenly
+these ceased. Almost at the same moment there was the crack of
+Buck's rifle, a groan and a moment later the scout was inside the
+barricade.
+
+"I guess I got him all right," he whispered, "he was makin' too much
+noise."
+
+This was the shot Ned heard miles away in the Cibola.
+
+Again for some minutes there was no sound and then, suddenly and
+from the left, came a spit of flame in the dark. Almost before
+Elmer heard the explosion Buck's gun had spoken in reply. Both
+bullets went wild, but Buck explained that it was necessary to give
+shot for shot, "and right at 'em," said Buck, "as it takes a little
+o' the ginger out o' them."
+
+But the besiegers had undoubtedly widened out. The next signs of
+them were two shots, almost together. Elmer's rifle made quick
+reply, but, to the boy's surprise, Buck failed to fire in return.
+The scout had disappeared from his companion's side. Before Elmer
+could call out he heard a rush at the end of the barricade, and then
+two explosions almost together and not ten feet away. He could not
+describe the sound that followed, but he knew that it meant the
+convulsions of human beings in agony. He whispered his companion's
+name, but there was no answer--only a gasp.
+
+In the black darkness the colored boy, revolver in hand, crawled
+forward. At the end of the barricade Buck's body was lying. As the
+boy's hand fell on the old man's breast he knew that it was blood he
+felt.
+
+"Buck," he whispered, "Buck! Is yo' hurt?"
+
+He put his arm under his friend's head. For a moment the unconscious
+form yielded and then convulsively straightened. Elmer knew that his
+companion and protector was dead.
+
+With strength that he did not know he had Elmer laid Buck's dead
+body behind the little wall of freight boxes.
+
+Then, as if by intuition, he sprang forward and found what he
+suspected--the unmoving form of an Indian. Unable to see, Elmer
+quickly felt over the adjacent ground with his hands and discovered
+the dead Ute's rifle. The revolver was gone. In the same manner he
+recovered both Buck's rifle and revolver, and then prepared to do
+his duty--to protect his employer's goods so long as he could.
+
+He was scarcely entrenched again, with the three magazine rifles
+laid on the barricade before him, when his straining ears heard a
+new sound. Far away and faint, but meaning only one thing, the soft
+chugging of a motor. The Cibola! There could be no doubt of it.
+The instant feeling of relief was shattered even as it gave Elmer
+new courage; to attempt to light the signal fires would probably
+mean instant death. And without them how would his friends know his
+position or peril? But one thing he could do; and even knowing that
+it would mean an answering shot from the skulking horse thieves he
+discharged his revolver into the air.
+
+Then the sound of the motor died away and the long minutes dragged
+by. When it began again, and more softly, the sound was nearer.
+Nearer, and nearer it came and then the circle of light fell on the
+wagon and was gone. "At least they know where I am," thought Elmer
+to himself, and settled down courageously for renewed attack,
+determined to hold out to the last. At this moment came the shot
+that put out the Cibola's light.
+
+The nervy boy had been tempted to abandon the wagon and follow the
+light, but his second judgment was against this. "If they can, the
+boys will come back," he argued, "and I'll only get out of this when
+I have to."
+
+To Elmer's surprise the attackers had been strangely silent for some
+time. With more experience he would have known that this meant even
+greater danger, but he only hoped it was due to the distracting and
+mysterious flying light. Then the sepulchral green light burst out
+in its funnel-like volume. It was coming back. It flared, went
+out, shot over the distant sands again like a searching' eye and
+then began moving straight up the river bank towards the wagon.
+Then came the earth rending explosion. Nor could the besieged boy
+know even then that Ned's well-aimed bomb had sent five Utes to
+their last sleep.
+
+When the sound of the explosion had died away and Elmer had
+recovered himself--for the shock had thrown him forward on the
+barricade--the whirr of the Cibola's motor was again far away. But
+it was directly above him!
+
+As if the attackers had been paralyzed by the explosion, the long
+interval continued without a shot. Then suddenly, from the right
+and left and front, the real attack began. One shot sounded as a
+signal, and then from a half circle before him half a dozen bullets
+tore their way towards the boy and his barricade. Most of them went
+wild. Two hit the boxes and half stunned the lone guardian behind
+them. The assailants did not know that one of the two white men was
+dead, and Elmer, in hopes temporarily to deceive them, fired two of
+the rifles at the same moment.
+
+But his enemies were closing in; the half circle was growing smaller
+and the crash of the bullets in the wagon above him and in the
+barricade in front told the boy that the end could not be far away.
+To the right in the direction of the explosion there was a gap in
+the fast closing circle. It was folly to delay longer. If escape
+were possible, it was in that direction. He would make one
+desperate attempt. One shot remained in his rifles. Putting it
+where he thought it would do the most good, and catching up the two
+yet full revolvers, the colored boy crawled under the wagon and
+crept hastily along the river bank.
+
+And yet he did not dare to attempt to pass the end of the Indian
+semi-circle. It was one chance in a thousand. Throwing himself on
+the ground, he waited. "Crack!" It was the rifle of an Indian, not
+fifty feet away and coming nearer. The stealthy footfalls told
+Elmer that his foe was heading straight for the river bank and that
+he was in the Ute's path. Then he could hear the Indian's deep
+breathing. Detection was inevitable.
+
+One last thing remained to be done--to kill the Indian and make a
+dash forward down the river bank. And he must act before his foe
+discovered him. Elmer's revolver flashed fire and he saw his foe of
+the red and yellow face bound into the air and then topple forward
+with a cry of anguish.
+
+The boy turned, but too late. Directly in front he heard the sudden
+shouts of other Indians. The river at his back! Flight down its
+cement-like bank was impossible. He might plunge forward and pray
+that the water was beneath.
+
+The death cry of the man he had shot and the echoing yells of the
+Indians behind him had been taken up by others. He knew the
+determined savages were making a final rush. Indian cries seemed to
+come from the very ground at his feet. He hesitated no lodger.
+
+As he turned to the river a sudden and strange wave of cool air
+struck down on him from above. Without reasoning he paused. That
+pause saved his life. In that swift moment he heard the low creak
+of something straining. His eyes pierced the black about him. Was
+it a shadow? Something was brushing by him like a great bird asleep
+on the wing. Then it was on him.
+
+"Ned?" It was only a whisper but it was enough.
+
+"Elmer, here, quick!"
+
+Even the whisper had brought an instant shot, but the colored boy
+had hurled himself toward the voice and an instant later a strong
+young arm was about the besieged lad.
+
+It was Ned Napier on the swaying ladder of the Cibola.
+
+"Cut away," came the low quick order and before even the nearby
+besiegers could locate the sound Bob Russell, high above, had
+slashed the lashings of a bag of ballast. The big balloon sprang
+forward, Elmer dangling in the air, and then settled again to the
+earth as the desperate colored boy found the last rung of the ladder
+and clung fast opposite his rescuer.
+
+"Another, another," called Ned springing up the fragile length of
+the doubly laden ladder.
+
+A thud on the ground told where another bag of ballast had fallen.
+The crash of the fallen fifty-pound bag of sand probably saved the
+Cibola. Shot after shot poured in the direction of the sound,
+although the Cibola, dragging forward, yet refused to rise. Elmer,
+at the bottom of the ladder, was helping the car onward in low
+bounds by touching the ground with one foot.
+
+Then the air craft settled again. Elmer's weight was too much. A
+mad thought came into the boy's brain. The Indians had located the
+new invader and yells nearby told that hot pursuit was already being
+made. Then the spit, spit, of new shots showed the risk the boys
+had taken. Elmer realized it. Should he hang on and endanger the
+lives of his friends, or should he let go?
+
+There seemed no time to think, but the boy's hand had already
+loosened when out of the black came the hot breath of the foremost
+pursuer. As the savage sprang forward Elmer's free arm gave him a
+blow full in the face. At the same instant the Cibola sprang upward
+like a bullet. A volley of shots rang out below, but they were too
+late. The balloon had saved Elmer's life, and even before the lad
+had made his way up the swaying ladder into the cabin it was a
+thousand feet in the air.
+
+
+
+
+CHATER XXIII
+
+CAMP EAGLE IN THE MOUNTAINS
+
+
+It seemed too wonderful to be true. But words were proof enough
+that Ned Napier and Alan Hope had found a new use for dirigible
+balloons. Faithful Buck's death was more than the loss of a
+companion. In the short time the boys had known him he had shown
+that under his rough frontier bearing he was a brave and honest man.
+
+"We can't go back now," explained Ned, "and we can't afford to land
+and wait for day. We can't all stay in the Cibola, and those of us
+who are landed must be left in a safe place. Our work," he
+continued turning to Bob, "is in the Tunit Chas Mountains, thirty
+miles west of here. It seems as if you had to know it. We'll go
+there to-night and land, if we can, on some isolated and inaccessible
+plateau. We'll make that our new relief camp and you and Elmer must
+take charge of it. To-morrow Alan and I will return in the Cibola to
+our abandoned wagon, bury Buck and bring away such of our stores as
+may be left. It's going to be a great loss, for I suppose the
+Indians have stolen everything. If the gasoline is gone it will cut
+short our work in the mountains."
+
+"I don't think it will be lost," said Elmer, quietly. "We tried to
+save it. We rolled it into the river."
+
+"But it will float away," exclaimed Alan.
+
+"Unless de tins caught on in de drift in de bend jes' below,"
+answered Elmer. "I seen four ob de eight tins dar befo' dark."
+
+"That's what I call genius," exclaimed Ned. "Elmer, you're a brick!
+And now our course is due east at half speed. By daybreak we'll be
+over the Tunit Chas. Until then, the rest of you turn in. I'll run
+the ship."
+
+Fifteen minutes later, despite the nerve-racking experiences of the
+momentous day, Alan, Bob and Elmer were wrapped in their blankets
+and sound asleep on the bridge deck of the Cibola.
+
+The night passed slowly, but Captain Ned stood the long trick at the
+wheel, happy and content. To feel the Cibola, the product of his
+youthful genius, at last moving forward in obedience to his
+slightest touch drove all thought of fatigue and sleep from him.
+
+But, above all, the early light of the coming day was to reveal to
+him a sight of the land of his hopes. There, before him, were the
+Tunit Chas; peaks and chasms of unsolved mystery wherein the
+centuries had held close their secret. Many trials had blocked his
+way. Was he now about to reap the reward of his labors? Did the
+hidden city of Cibola lie somewhere below him? Or were the Palace
+of the Pueblos and the Turquoise Temple but empty myths?
+
+The young aeronaut's present plans were simple enough. The Cibola
+had now been afloat twelve hours and nearly half her gasoline was
+exhausted. More than once in the night Ned had noticed that the
+balloon was settling lower and he had been forced to maintain his
+level by casting over ballast. It was apparent that they were
+already losing gas.
+
+In boyish impulse and sympathy they had made Bob Russell, the young
+reporter, a third and unexpected passenger, and accident had forced
+them to add Elmer Grissom, their colored friend and servant. And
+these extra occupants of the car must be landed at the earliest
+opportunity.
+
+This became imperative now because, the relief and supply station on
+the Chusco river having been destroyed, the Cibola must add enough
+ballast and gasoline to make its exploring tour in the mountains in
+one journey. The original plan had been to make quick dashes to
+the camp on the Chusco for gasoline and then return to the
+mountains. To provide for this new weight the two new passengers
+and a good portion of the air ship's stores must be landed. And the
+most feasible plan seemed to be to set up a new emergency camp in
+the heart of the mountains.
+
+Many things might happen to the now perfectly working balloon. And,
+even if cast away in the mountains, it was no part of Ned and Alan's
+plan to cease searching for the temple of treasure until dire
+necessity drove them from it. In case wreck and privation came it
+would be comforting to know that somewhere in the same wilderness
+food and friends awaited them.
+
+The first glow of the sun painted for the ever watchful pilot a
+picture beyond the possibilities of brush and canvas. Here and
+there out of the blackness below sprang rosy points, the sun-tinted
+peaks of the Tunit Chas. Down the mountain sides, like rivers of
+silver pink, fell the sun's light. Then the valleys began to open
+out of the chasm of night-dark canyons wrought in the wilderness of
+the mountain sides. Here and there, oases left by the devastating
+hand of time, rose high plateaus, tree-crowned and verdant. And
+then, higher up among the white peaks, sentinel-like, stood giant
+tables whose brown tops and precipitous sides told of inaccessible
+and arid wastes. "And somewhere," said Ned to himself, "in this
+Titanic chaos lies the object of our search."
+
+Starting at half speed, Ned had soon reduced the engine to quarter
+speed. When he aroused his sleeping companions Wilson's peak, their
+chief landmark, was just in sight far behind. His calculations
+placed the present location of the Cibola thirty miles from the
+Chusco river and just over the eastern Tunit Chas Mountains.
+
+"All hands turn to," shouted Ned cheerily, "and stand by to make a
+landing."
+
+There was a scramble, a rubbing of yet sleepy eyes and then an
+outburst of admiring wonder. The Cibola had sailed over two broken
+ridges enclosing an irregular, broken valley and was now looking
+down on a shelf-like plateau abutting on the second ridge and west
+of it. On three sides the plateau dropped precipitately into a
+lower rock-strewn, valley. On its eastern side it joined the still
+higher ridge. A pine forest crowned the top of the shelf-like
+mountain side and then ran up to the higher slopes until the carpet
+of green faded into the brown wastes of the timber line. In the
+very center of the wilderness of trees glistened a little lake of
+mountain water. From it the silver thread of a rivulet wormed its
+way for a mile or more among the trees and then trickled over the
+side of the cliff in a vapory waterfall.
+
+Ned had swung the Cibola into a wide curve and the balloon and car
+were soon directly over the mountain creek. He threw the aeroplane
+guides downward and the slowly moving car drifted lower until it was
+but four hundred feet above the water and the overhanging pines.
+Then, following the water course beneath, the air ship floated back
+into the woods and the little lake widened out beneath them. Two
+deer, at the water's edge, stood unalarmed. On the south of the
+lake a grassy opening indicated Ned's destination.
+
+"Here," he explained, "we can make a safe landing. It is an ideal
+place for a camp, with plenty of firewood and water."
+
+"And meat, too," interrupted Alan, pointing to the deer.
+
+"Venison and bear meat too, no doubt," laughed Ned.
+
+From the top of a dead pine tree an eagle rose and soared lazily
+away.
+
+"It's like the camping out places you read about," exclaimed Bob.
+"That eagle nest completes the picture."
+
+"It does," interrupted Ned, "and I hope you won't forget the
+picture. That high, barren tree is your landmark. Some day you may
+need it. Remember; from the valley below your camp can be found by
+locating the little waterfall on the cliff. From the timber line
+above you will know it when you see the eagle's nest. And now let
+go the anchor. We have no gas to spare, and can't afford to open
+the valve."
+
+To make a landing in a balloon without throwing open a valve and
+wasting precious gas is almost impossible. The craft could only be
+kept near the ground by keeping it in motion or by causing the
+propeller fans to depress currents of air on the aeroplanes.
+Therefore, as soon as the engine stopped, the Cibola would mount
+higher. But resourceful Ned had long since thought out this
+problem.
+
+The engine's speed was reduced and the anchor was quickly lowered
+until it caught hard and fast in a strong pine tree. The contact
+shook the fragile car and sent the bag bounding, but when it was
+seen that the iron had fixed itself firmly three of the boys,
+pulling on the anchor rope, gradually drew the great buoyant car
+down until it floated just above the tree top. To drag it lower
+was, impossible, for one sharp branch might injure the bag beyond
+repair.
+
+When the ship was safely anchored just above the tree, the
+twenty-five foot landing ladder was lowered and Ned himself made his
+way down its fragile rungs into the tree. .
+
+"Hold on tight," he continued, "I'm getting off."
+
+As he did so and found footing in the tree branches the Cibola
+tugged to free itself, as if, overjoyed to be rid of Ned's one
+hundred and forty-five pounds of weight. As soon as the young
+commander was safely on the ground he ordered the other boys to pay
+out the anchor rope and again the Cibola rose in the air.
+
+"Now," ordered Ned, "start your engine and head the car over the
+opening."
+
+While Ned stood below directing, with hands to his mouth,
+trumpet-wise, the Cibola strained at her anchor rope and then,
+obeying her rudder, moved directly over the open space, her nose
+pointing skyward at an angle of forty-five degrees.
+
+"Hold her," yelled Ned, "and haul back."
+
+The boys again strained at the taut anchor rope until the car stood
+just clear of the trees and some two hundred feet in the air.
+
+"Now lower your drag rope and an empty ballast bag," called Ned.
+
+While this was being done the navigator of the Cibola was busy
+carrying chunks of broken rock from the margin of the little lake,
+and in a short time the boys above were hauling away on the rope and
+lifting aboard new ballast. With each bag of it the Cibola sank
+lower and lower, until finally, when it was almost balanced in the
+air, Ned easily drew the balloon to the ground.
+
+But the landing was not yet finished. Not a passenger in the craft
+could step ashore until Ned had added more stone. But when enough
+of this had been lifted up to the hands above, and Elmer could
+alight, the two willing workers on the ground soon made it possible
+for the other boys to spring overboard. Then the four of them
+loaded enough more rock on the bridge to take the place of the
+stores to be landed.
+
+There were not many things that could be left: water, and half the
+provisions and, preserved goods; a few cooking utensils; blankets,
+an extra compass, two revolvers, a hatchet and saw; a light silk
+tent; matches and candles, a medicine case, ammunition, and, to make
+way for the gasoline that it was hoped might be recovered, all the
+extra oil on board--for the reservoirs yet contained an ample supply
+to make the trip back to the scene of Elmer's attack.
+
+At a safe distance from the balloon Elmer had returned to his
+favorite occupation. He got a fire going and while the other boys
+replaced the rocks on board with bags of sand from the margin of the
+lake the colored lad made hot coffee and broiled some bacon. It was
+a luxury after the cold, dry food of the long night.
+
+"When you come back this evening," exclaimed Bob jovially, "I'll try
+to have a juicy venison steak."
+
+"An' hot biscuits," chimed in Elmer.
+
+"And a good bed of balsam boughs," added Bob, "and a fine camp fire,
+and we can sit wound it and talk it all over."
+
+"And if we don't get back to-night you'd better have your camp fire
+anyway," said Ned,
+
+"Ain't you goin' to git back to-night?" ruefully interrupted Elmer,
+as he poured the smoking coffee.
+
+"You never know what you are going to do in a balloon," answered Ned.
+"If we can we will. If we can't we won't. If we are not back
+to-night we may not be here for several days. We've got work ahead
+now, and plenty of it."
+
+"We'll be here when you come," replied Bob earnestly, with a smoking
+bit of bacon in his fingers, "whenever that is."
+
+"No," replied Ned, "if we are not here in six days you must make
+your way out to civilization. You have food enough but you can't
+wait longer than that. As for directions, all I can say is that
+from this ridge back of us you can see across the half desert valley
+to the higher range of mountains. Should you cross the valley
+bearing almost due east and be able to get over or through that
+second ridge you will be able to see the top of Mount Wilson, thirty
+miles further east. From Mount Wilson it is fifteen miles southeast
+to the camp Elmer made. There you should pick up the trail of
+Buck's wagon back to the railroad eighty-five miles south."
+
+Bob's eyes opened.
+
+"Is it as bad as that?" he said half laughing. "We'll certainly
+have to get busy if the Cibola breaks down."
+
+"Or," went on Ned, "any strewn in the valley below here flows
+finally into the San Juan River to the north. If you can make your
+way to this river and then succeed in following its banks eastward
+until you reach the plains, some time or other you'll find a
+frontier settlement."
+
+"Or Utes," interrupted Alan.
+
+"Gib me de mountain road," exclaimed Elmer quickly.
+"Nomo'Utesfo'me!"
+
+"Yes," added Ned, "that's the trouble. The route to the San Juan is
+not only through a barren, broken mountain region, but it gets you
+finally right into the Southern Ute reservation. And, remember,
+too, that this is Navajo land. Your safety with them, should you be
+discovered, will be in diplomacy. And now good-bye--until we meet
+again."
+
+"And if we don't," replied Bob, huskily, taking the hands of the two
+boys in turn, "I just want to say again that you boys have done for
+me what I can't forget and what I can't repay. I don't know why you
+are here, and I don't want to know. What I've seen will never be
+revealed, when I get back to Kansas City and the Comet, until you
+tell me I am free to tell it. And you'd know what that means to me
+if you knew what a cracking good yarn my experience has given me
+already. Good-bye and good luck!"
+
+Ned and Alan clambered aboard; the rocks were cast overboard, and as
+the Cibola shot skyward the boys could hear Elmer calling:
+
+"Member, boys--we all'll be at Camp Eagle an' supper will be
+awaitin'."
+
+
+
+
+CHAPTER XXIV
+
+A GRAVE IN THE DESERT
+
+
+But Ned and Alan did not eat with their friends that night, nor for
+some days to come. And when they saw each other again one of
+Elmer's juicy venison steaks would have seemed to all of them the
+sweetest morsel ever eaten by man.
+
+Ned only waited to help inflate the balloonet in the big balloon
+with the little hand blower for the Cibola showed quite perceptibly
+the loss of gas after her twenty hours of inflation. Then, the
+course having been laid, he left the wheel and engine to Alan's care
+and turned in for his long needed rest.
+
+Alan had determined on a record flight. He allowed the Cibola to
+rise higher than it had yet flown, about 5,000 feet, and then
+setting the aeroplanes on a slight incline he headed the car on a
+down slant for Mount Wilson's just visible peak, thirty miles away.
+
+There was no economy in half speed, for time and the utilization of
+their gas were more precious than gasoline. "We can always float
+without gasoline," the boys had said to themselves, "but we can't
+move without gas." Therefore the Cibola was soon at its maximum and
+the enthusiastic Alan knew that Ned would have a short sleep.
+
+In an hour and twenty-one minutes the swift dirigible was abreast of
+the peak of Mount Wilson, and then, without slackening speed, Alan
+altered her course southeast toward the scene of the previous
+night's hair-raising experience. Long before he reached the place
+he was able to make the juncture of the two rivers his landmark, and
+the ship pointed her course as straight as a railroad train. After
+thirty minutes sailing from Mount Wilson, Buck's rendezvous could be
+made out, three miles beyond.
+
+One glance told the whole sad story. Two dead horses alone marked
+the spot where their freight wagon had stood. Alan aroused Ned, and
+as the Cibola sailed low over the place the boys saw that the
+thieving Utes had gone--with the wagon, horses, freight and their
+dead companions.
+
+Poor Buck's body was lying where the brave escort had fallen.
+
+"We can't make two landings," suggested Ned. "We'll find the
+gasoline and then come back and bury our friend."
+
+Disappointed, although they had really in their hearts expected
+nothing less, the young navigators turned the Cibola and sailed
+slowly down the river in the hope that the gasoline would be found
+where Elmer had described it as lying.
+
+They were as richly rewarded here as they had been previously
+disappointed. The drift, a tangled jumble of small mountain wood,
+had caught and preserved seven of their eight tins of gasoline.
+
+It was now noon, and broiling hot, but luncheon was not thought of
+and the difficult work of recovering the heavy packages was begun.
+This presented a new difficulty, for again the boys were determined
+not to lose any gas in making a landing.
+
+The drift was too light to hold their anchor although two trials at
+this were made. Not a bush or tree was to be found nearby. In
+despair at last, Alan was about to suggest opening the valve--for it
+was imperative that they secure the gasoline--when Ned turned the
+bow of the craft down stream.
+
+"Perhaps we can find anchorage further down," he explained.
+
+"But if will be pretty hard work carrying these tins," Alan began.
+
+"They floated where they are, didn't they?" smiled Ned. "What's the
+matter with letting them float a little further?"
+
+His hope was realized. But the solution was fully a mile away. On
+a sandy bar, half buried in the sand, the stout end of a cottonwood
+trunk, the flotsam of some extraordinary freshet, had come into
+view. The experience of the morning was repeated, but on a smaller
+scale, for here were no dangerous tree limbs to threaten their
+delicate silken bag. After two trials and much pulling and hauling
+the car of the Cibola was tied fast to the snag, half over the
+shallow water and half over the sand.
+
+Then, naked as when they were born, and suffering not a little from
+the pitiless sun, the boys started afresh. Alan made his way back
+up the river and began to prod out the stranded tin casks. All were
+soon bobbing along in the slow current, with Alan behind them like a
+lumber driver of the northwest dislodging logs left in the shallows.
+Ned below soon had all of them in shallow water.
+
+By means of a coil of the drag rope, looped in turn about the tins
+of recovered fuel, Ned lifting below and Alan pulling above soon
+transferred the gasoline to the bobbing Cibola. As each cask
+ascended, a portion of the extra ballast was dumped overboard.
+
+Then, dressing themselves and improvising what tools they could, the
+boys made their way sorrowfully to the scene of the previous night's
+tragedy. Buck's body was carefully removed and decently buried. A
+mound of boulders was made over the grave to designate the spot, and
+with the hope that some day they might return and suitably mark the
+desert tomb the boys took a mournful farewell.
+
+
+
+
+CHAPTER XXV
+
+BARTERING STORES A MILE IN THE AIR
+
+
+"And now," said Alan, "it's ho, for Camp Eagle and our search at
+last."
+
+"I don't know about all that sentiment," answered Ned, thoughtfully.
+"I've been--"
+
+But he was interrupted. The boys, aboard the Cibola again, were
+just about to cast off when Alan cut short Ned's remark with an
+exclamation.
+
+"Isn't that a balloon?" he exclaimed pointing to an orange-like
+object high in the heavens toward the west.
+
+Ned caught up the binoculars and had a quick look at the rapidly
+moving ball which was rushing toward them from over the distant
+Tunit Chas Mountains.
+
+"No question about it," answered Ned, handing Alan the glasses; "a
+balloon, and a big one."
+
+"And out here, too!" commented Alan in surprise. "I guess the world
+is pretty small after all."
+
+"Everything ready?" asked Ned eagerly. And then as the retaining
+rope was untied from the frame of the car and slipped down and out
+from under the cottonwood snag the Cibola shot upward.
+
+"I have an idea," continued Ned, "and please don't object until you
+think it over. Let's make a little social call on the stranger!"
+
+"A call!" exclaimed Alan, plainly showing his astonishment; "a call
+on a balloon five thousand feet in the air?"
+
+"Certainly. We are going that high anyway. And we have the means
+of going where we like. If we go up until we strike the same,
+stratum of air the stranger is moving in we have our propeller and
+aeroplanes to check and guide ourselves. When it passes we can
+easily run alongside!"
+
+"Well, if that isn't the limit!" laughed Alan. "And I suppose we'll
+exchange greetings and messages like ships long at sea."
+
+"And," added Ned, "we can send some word to Major Honeywell. You
+can see our fast flying friend isn't going to stop around here."
+
+The Cibola was rising fast and the two air craft were coming closer
+and closer. As the dirigible reached the altitude at which the free
+balloon was sailing Ned put the aeroplane in operation, stopped the
+ascent of the Cibola and then, sweeping his own car into the same
+direction with the other balloon he reversed the propeller and held
+his own craft against the breeze until the stranger swept by.
+
+Then, throwing on the propeller again at full speed, Ned made the
+Cibola bound after the other craft, and in a few minutes, aided by
+the favoring wind, they were within hailing distance.
+
+Ned was on the bridge, his face flushed with the novelty of the
+race. A mile above the earth, the two air ships came closer until,
+as if running on parallel tracks, they were nearly together and
+abreast.
+
+"Balloon ahoy!" exclaimed Ned at last and in true maritime style.
+
+"The Arrow of Los Angeles, bound across the continent," came the
+sharp answer.
+
+"The Cibola from Clarkeville, New Mexico," called Ned in reply,
+"exploring. Please report us over Mount Wilson."
+
+Then the two ships of the sky came closer. The boys could see that
+the Arrow was well equipped for its purpose. Two determined looking
+aeronauts were leaning from the heavily laden car.
+
+"Need anything?" shouted the Arrow cordially.
+
+"In good shape," answered Ned, "but a little short on provisions."
+
+"Plenty here," came quickly from the Arrow, "glad to exchange
+fifty-pound emergency rations for ballast."
+
+"All right," responded Ned, "stand by to make a line fast."
+
+Alan, at the engine, brought the air ship up as skillfully as a
+pilot might a vessel, and as the two cars almost touched Ned passed
+the end of his drag rope, and the occupants of the Arrow with a
+quick turn made her basket fast to the bridge of the Cibola. There
+were handshakes, mutual congratulations and quick explanations. The
+Arrow, the property of a wealthy amateur balloonist, was attempting
+to sail, from the Pacific to the Atlantic and was, so far, beating
+the best calculation of her owner. In reaching the desired height
+that morning, however, much ballast had been used and the
+possibility of a renewed supply was jumped at.
+
+"These extra provisions were packed with the idea of possibly using
+them as ballast and we don't really need them. And, so," they
+explained to the boys, "if you do you had better take them and give
+us sand."
+
+The exchange was quickly made, and then, having stored their new
+food supply safely on the bridge, they said hasty farewells.
+
+Ned had scribbled this note on a page from his note book: "Major
+Baldwin Honeywell, Annex, Chicago. By courtesy of Balloon Arrow.
+Bourke, escort, killed by Indians. Search begins at once. Camp
+established on plateau, second range Tunit Chas Mountains, thirty
+miles due east Wilson's Peak. Greetings. Written 5,600 feet above
+San Juan River, New Mexico. Ned Napier and Alan Hope."
+
+The case of provisions weighed a trifle more than the ballast given
+in exchange, and as the line holding the two cars together was cast
+off the Cibola sank slowly below the level of the Arrow. Then, as
+the Cibola's engines began to push the car ahead in a wide turning
+circle, Ned called up to the disappearing Arrow:
+
+"Great country, this New Mexico, where you can buy food with sand.
+Good-bye and success to you!"
+
+The answer was lost in space as the ships parted.
+
+"And now," said Ned, after lashing the now case of provisions to the
+bridge netting, "we've wasted some more precious time. Do you still
+think we had better lose a night at Camp Eagle? We have all the
+fuel we can carry."
+
+Alan saw what was in the wind.
+
+"We have extra provisions, water and gasoline. My own judgment is
+we had better make at once for our starting point."
+
+"I guess you are right," answered Alan after long thought; "I don't
+know what is to be gained by the trouble of a landing at the camp by
+the lake."
+
+"Nothing but that hot supper," smiled Ned, "and we'll have to put
+that off a few days, I think."
+
+"All right," agreed Alan, "set your course and with luck we'll do a
+little treasure hunting before dark."
+
+This being settled, the prow of the Cibola was pointed a little west
+of northwest, and, dropping to a lower stratum to escape the lively
+eastern breeze at the higher altitude, the boys started at last
+directly for the and arid broken mountains of Northwestern Arizona.
+
+This region, bordering on the great sand dunes lying beyond the
+Chelly River, was to be the beginning point of their arduous and
+momentous search. From that place to a point nearly one hundred
+miles to the southeast lay the secret fastnesses of mountain, canyon
+and mesa wherein, somewhere, according to the Spanish soldier's
+record, was the secret city of a dead race and the treasure that had
+brought Ned and Alan half way across a continent.
+
+What such a search meant one glance at the monotonous and unending
+rock easily told. On foot, only the compass could lead a man
+forward in such wilderness of abrupt heights and winding chasms. As
+the boys meant to manage it, the attempt had possibilities, but it
+might mean days of drifting, of watching, of doubling back and forth
+over every possible site. And that was now their task.
+
+So far as they could, Ned and Alan meant to begin at the extreme
+northern end of this unknown land and, sailing back and forth from
+east to west, cover every foot of exposed ground with their powerful
+glasses.
+
+Both boys had long since agreed in this conclusion: the "city" meant
+no more than one large structure similar to but on a larger scale
+than those found in the Chaco Canyon at the extreme southern end of
+the Tunit Chas Mountains. This would be indicated now by nothing
+more than rectangular lines of wall stones, probably in piles,
+outlining the shape of the "city" or palace. Prominent among these
+ruins should be the more elevated temple, the object of their
+search. And beneath this should be found the underground "khivas"
+or religious chambers.
+
+That this "city" was secret or hidden was proof to Ned and Alan and
+Major Honeywell that it would not occupy a prominent place such as
+an exposed plateau or a high level mesa. Only one other location
+was left, the abutting shelf of some canyon. And the young
+navigators had pictured to themselves that, if this should prove to
+be the location, the shelf would be so elevated as not to be visible
+from the front or below and that it would be concealed from above by
+an extended and overhanging cliff.
+
+"Look for it as you would look for a bird's nest in the cliff,"
+suggested Ned. And that was the plan of search.
+
+It was nearly three o'clock when the boys had bade farewell to the
+Arrow and about half past five when the Cibola sailed over the
+second ridge of the Tunit Chas. But the course was far to the north
+and there was naturally no sign of the waterfall plateau or Camp
+Eagle. For a time they thought of passing over the camp and
+dropping a message, but this pleasant idea was given up.
+
+"Although," as Alan expressed it, "one of Elmer's hot suppers and a
+soft bed of balsam boughs to-night wouldn't be bad."
+
+Ned thought of the four nights of hard floor and agreed, but he
+said:
+
+"You'll have to forget soft beds if we're ever going to find Cibola.
+We'll come down to-night, though, and make a camp of our own with a
+fire and a pot of coffee, and at daybreak we'll be off."
+
+The boys had taken a light luncheon just after starting on the
+return trip, and now, soaring over the Tunit Chas again, they began
+to be anxious for night and supper.
+
+At seven o'clock the peaks and ridges below them had begun to drop
+into foothills and as the great sandy deserts of distant Utah and
+nearer by Arizona came before their eyes the boys decided that it
+was time to anchor for the night. They were sailing over the
+eastern slope of the last low ranges of hills, barren of trees or
+vegetation. The aeroplanes being given the proper depression, the
+Cibola shot earthward and then, the propeller coming to a pause,
+floated gently along above the jumble of rocks. Making fast the
+anchor in a ragged pile of these the boys soon drew the Cibola to
+the ground and lashed her fore and aft to heavy boulders.
+
+The firm ground felt delicious to the tired boys and they refreshed
+themselves with a brisk race over the open space between the rock
+piles. Then came Alan's camp fire, a hot supper and preparations
+for a good night's rest. There were no pine needles of balsam
+boughs, but fatigue made a fine mattress, and it was not long before
+the tired boys, rolled up in their blankets, were fast asleep on the
+soft sand.
+
+"I hope," said Ned drowsily as they were dropping off to sleep,
+"that we won't have any Jack Jellups or thieving Utes to-night. My
+nerves need rest."
+
+Then the boys got eight good hours of health and strength giving
+sleep in the tonic air of the Arizona Mountains.
+
+
+
+
+CHAPTER XXVI
+
+THE SECRET TUNNEL IN THE MESA
+
+
+At five o'clock Ned and Alan were astir. With regrets that they
+were not at Camp Eagle for a plunge in the cool mountain lake, they
+prepared another hot meal, ate it, and boarded the Cibola.
+
+The balloon had now been inflated thirty-eight hours and was
+noticeably showing the loss of its gas. While the top of the bag
+was yet round and firm in the heat of the sun the lower sides had
+become a trifle flabby as the cool evening had come on. Up to this
+time all records for balloon flight had been broken a fact due to
+the renewed buoyancy caused each day by the hot, Southwestern Sun.
+And, exploration in and quick ascent from the canyons before them
+would before long call for the use of ballast. The boys agreed that
+the time had arrived to utilize their liquid hydrogen. The
+shrinkage that night had been quite perceptible.
+
+They regretted that but two-thirds of this remained--about eleven
+cubic feet. This when reconverted meant nearly twelve thousand
+cubic feet of new gas at their present altitude. As the work of
+converting the gas involved care, preparation for it was made before
+the Cibola was cut loose.
+
+The reconverter, a reduced inversion of the apparatus used in making
+liquid air, was made ready. When the muffled explosions and the
+heat of the tubes told the boys that the reconverter was working
+perfectly and pumping new and needed gas into the shrunken Cibola's
+long bag, the lashings were loosed and once more the faithful
+dirigible mounted skyward.
+
+With Major Honeywell's map of the region spread out on the deck of
+the bridge and the binoculars in hand Ned began the long anticipated
+search for the lost city.
+
+All day the process of turning the liquid hydrogen back into buoyant
+gas went on. And all day the Cibola wound her devious course over
+the peaks and chasms beneath. By night half the hydrogen jars were
+empty and Ned and Alan saw the evening close in on them without a
+sign of the object of their search. When darkness stopped further
+work the balloon was brought to earth and camp made again.
+
+The following day, as uneventful as the first, gave no indication of
+the secret city. The rest of the liquid hydrogen was transformed
+into gas. The sun seemed to enfold the craft in a fiery embrace.
+When camp was made again that night the Cibola had been afloat
+eighty hours.
+
+"I think she is good for another forty-eight hours," said Ned that
+night. "If we find nothing in two more days we'll have our choice
+of going out on foot or of quitting in time to pick up Elmer and Bob
+and make a dash to civilization. What do you say?"
+
+"I don't know," replied Alan, "I'd hate to give up as long as we can
+fly. I think the boys can care for themselves. Let's stick to it.
+We have provisions and there is water in some places."
+
+"Well," answered Ned, "we'll have two more days time in which to
+decide."
+
+The next morning the Cibola showed plainly that her gas was rapidly
+escaping. New life was given to the balloon by casting overboard
+some empty hydrogen casks. The fourth day broke hotter than ever.
+In all the wilderness examined by the tired and strained eyes of the
+searchers, not a human being had been seen--not even a wandering
+Navajo. This day they began the search with renewed vigor, but with
+the same monotonous result--miles of hopelessly desert rock and sand
+beneath them, with a little vegetation now and then, but so sign of
+Indian remains.
+
+At noon Ned said:
+
+"If we were not in a balloon with a compass and sextant I should say
+we were lost. And if Indians ever lived and died hereabouts they
+certainly left so signs of their bones."
+
+By six O'clock, with the sun gratefully low, Alan expressed
+discouragement.
+
+"To-morrow at this time," he said, "if we see no indication of the
+old palace or city or whatever it was--if it ever was--I think I'll
+vote to try to find Camp Eagle and get out."
+
+"We'll see to-morrow," answered Ned stoutly.
+
+That night at dark, a landing was made on the ledge of a point of
+land ending in a rounded cliff pointing south, selected because the
+place was open to the breeze and cool. The Cibola had approached
+the height from the west, and the boys believed that the promontory
+projected from yet higher ground beyond. On those portions of the
+cliff that they could see there was neither shelf nor projection of
+any kind. The walls rose almost like cut stone and were apparently
+about three hundred feet high. As the Cibola was about to descend,
+Alan, who was taking a last survey from the bridge, called Ned's
+attention to the fact that even the far side of the supposed
+promontory was separated from the mountains beyond, and that a chasm
+at least a half mile wide separated the two heights.
+
+"It's a mesa," replied Ned with renewed enthusiasm, "and it will be
+a good thing to look over it to-morrow. These high and almost
+unapproachable islands of rock were favorite dwelling places for the
+Indians."
+
+"But a temple up here wouldn't be a secret very long," replied Alan.
+"We've seen this point all afternoon. It's prominent enough."
+
+"That's so," answered Ned, "but we are here, so let's make a landing
+and eat, and dream over it."
+
+The balloon had now lost so much gas that a landing was easy, and,
+tired with four days' profitless search and its strain, the young
+aeronauts were soon beyond even dreams.
+
+It was with no small alarm that the boys saw, when they awoke with
+the first rays of the sun, that the car of the Cibola, which had
+been anchored fore and aft to heaped up rocks during the night, was
+now resting on the ground. Gas, was rapidly escaping. But fortunately
+the aeroplanes and propeller had been left properly in a horizontal
+position and no damage had been done.
+
+The boys knew that by throwing over enough ballast and stores the
+Cibola could be made good for one more flight, but that probably it
+would be the last. Therefore, the inevitable seemed forced upon
+them. They would fortify themselves with a good breakfast, look
+over the mesa, make one more circling flight and then attempt to
+find Camp Eagle. While Alan made haste to prepare breakfast, Ned
+determined first on an examination of the mesa point by daylight.
+
+The rock had a top area of perhaps forty or fifty acres. It had a
+rolling surface and was coated with a carpet of dusty sand, except
+in the northwest corner. The northern end of the mesa, Ned could
+see, widened and ended in a sharp rise almost wall-like in form. At
+the western end this wall-like elevation turned the corner and
+extended south a short distance, finally dropping down to the
+general level of the mesa. In this protected comer grew a strange
+grove of gnarled and twisted pines, ill nourished and apparently
+very old. Between this comer of the mesa and the sharper promontory
+whereon the Cibola had come to anchor, was a wide, sandy, barren
+depression.
+
+The narrow portion of the rocky island where the boys had made camp
+drew in abruptly to make the point that marked the southern end of
+the mesa. Ned turned first toward the point.
+
+When he had advanced, making his way slightly upward all the time,
+to where the narrow mesa was not over four hundred feet wide, the
+lad was astounded to suddenly discover a deep and narrow fissure or
+chasm. It was dark, with sides as abrupt as the cliffs of the mesa,
+and too wide to jump across. A cold air was already rising from the
+opening into the warmer atmosphere above.
+
+In his astonishment Ned called to his chum.
+
+"What surprises me," exclaimed Ned, "is the character of the
+opening. If it extended from cliff to cliff I should say that the
+same freak of nature that made this solitary island of rock also
+split off this end at some time. But it is closed at each end."
+
+Alan hastened to the end of the fissure, near the side of the mesa.
+
+"It looks to me," he said, "as if it had extended entirely across at
+some time and the ends walled up later."
+
+The boys made a closer examination.
+
+"You're right," said Ned when he discovered that each end of the
+rift had been filled with closely fitted rock, "and human hands did
+it."
+
+Alan sprang up in excitement.
+
+"That's the first sign we've had," he exclaimed. "Do you suppose it
+means anything?"
+
+The edge of the cliff was so abrupt that the boys had to lie down to
+look over in safety.
+
+"It does," Ned answered. "The reason you can't see that chasm from
+below or from in front is because the face of it is walled up. And
+it is walled so skillfully that you can't detect it from even a
+short distance."
+
+"That's to hide something," quickly replied Alan, "but I don't see--
+"
+
+Ned was standing on top of the short filled-in portion of the chasm.
+
+"Look!" he exclaimed, suddenly interrupting his friend. "These
+stones are steps, and, they are worn!"
+
+
+
+
+CHAPTER XXVII
+
+THE TURQUOISE TEMPLE DISCOVERED
+
+
+In another moment he had sprung forward and was quickly descending
+into the narrow, dark pit, with Alan close behind. A cave-like
+smell and a rapidly, cooling air greeted them. They were soon in
+almost complete darkness. When the walls had narrowed to but a few
+feet, a thin ribbon of blue sky was all that could be seen above.
+
+The steps had come to an end. An ascending elevation began just in
+front of them. This they made out by the light of a match, which
+flickered uncertainly in the bad air. Bats dashed against the walls
+and every movement was followed by a cloud of dust.
+
+"Do you feel anything?" suddenly exclaimed Alan. "Seems to me like
+a current of air on my feet."
+
+Ned lit another match.
+
+Before them they again made out an ascending slant such as they had
+come down. But the base of it was hollowed out in the form of a
+small cave. As the light went out both boys stooped to look further
+into this opening.
+
+"Light!" they exclaimed almost together.
+
+They were looking through a tunnel made, as they afterward found, in
+the base of the filled-in portion of the chasm. Reptiles, bats and
+dust were forgotten now. Plunging forward on their hands and knees,
+the two boys advanced without difficulty to the distant mouth of the
+tunnel.
+
+It ended abruptly in the face of the mesa cliff, one hundred feet
+above the valley below. There was not the slightest ledge below it
+and the side of the mesa dropped so precipitately that access to the
+tunnel mouth from without seemed impossible. The possibility of a
+climb to that entrance to reach the mesa above was out of the
+question.
+
+The boys, panting for breath, lay on the floor of the tunnel with
+their heads just out of the opening.
+
+"Some one has used this place, but how did they ever get up here?"
+asked Alan.
+
+"I don't know and I don't care," said Ned with excitement. "But I
+do know that this entrance is concealed. Why, you couldn't even see
+it from below--it's so small. And it was made that way for a
+purpose. That must mean Cibola. Let's get busy."
+
+There were one hundred and thirty-five steps to mount, and each was
+about a foot and a half high. When Ned and Alan were on top of the
+mesa again they were out of breath and their clothes were white with
+dust. They were also choked, thirsty and hungry.
+
+"Eat heartily," laughed Ned, when they began breakfast over again;
+"we are going to have a busy day, I hope."
+
+"What is your theory?"
+
+"That our treasure is right here if it is anywhere," exclaimed Ned.
+
+Alan laughed. "The place is barren as a barn floor," he said; "I
+don't see any very large palace or temple hereabouts."
+
+"I don't either. That's why I'm going to look for it--and look
+hard."
+
+"And our gas slipping away at a lively rate!" interrupted Alan
+again.
+
+"Let it all go," said Ned. "We know how we can get down within a
+hundred feet of the ground, anyway. That's some consolation."'
+
+"First we will make a circuit of the north end," continued Ned,
+after breakfast, "and if nothing comes of that--no unseen hollows or
+new crevices--we'll try this sandy hollow, even if it is smooth as a
+plain."
+
+The circuit of a fifty-acre area requires time and it was an hour
+before the boys had traversed the edge of the precipitous cliff. At
+every few yards they examined the face of the mesa for gaps or shelves,
+but there seemed hardly a resting place for a bird.
+
+Tired and hot, the sun being now high above them, the young
+aeronauts finally reached the north-eastern corner of the mesa
+without finding a sign or suggestion of Indians, or even of animal
+remains.
+
+Alan had thrown himself on the ground at this point for a rest, when
+with an exclamation Ned darted from his side. As Alan's eyes
+followed him he saw the cause of the exclamation. From where they
+stood--directly east from the ancient grove--they could see for the
+first time that the trees stood in a wide double semi-circle, and,
+directly in the center, perhaps fifteen feet in height, arose a
+column of masonry. It was snow white in color and glistened like
+glass.
+
+There was no question about it.
+
+The fabled Temple of Turquoise, its deep blue glaze lost in the
+whitening sun of three centuries, stood before them. Almost
+overcome with the emotion of success the two boys stood as if
+transfixed. Then cautiously, as if afraid the wonderful pile might
+dissolve itself into a dream, they moved forward.
+
+In this protected corner of the mesa where the winds of ages had
+gradually deposited a thin sandy soil, the hand of man had planted
+two almost complete circles of trees. Therein, and generally
+agreeing with the record of the long dead Vasquez, were the plain
+outlines of a stone structure. At places, where the walls crossed,
+and at some of the corners, the masonry yet rose to the height of a
+man. And again, it fell into long irregular piles of jumbled
+blocks. Sifted sand filled each corner and crevice.
+
+In the center of the ruins rose the turquoise column. From this,
+and in a line with the true east to where the boys stood, extended
+an open approach. Almost reverently Ned and Alan advanced up this
+walk.
+
+It was easily seen that the structure had contained a maze of
+rooms--over three hundred, they afterwards discovered--and that the
+white column stood in a hollow square.
+
+"It's white," almost whispered Alan.
+
+"Yes," answered Ned; "it ought to be blue."
+
+They were now at the foot of the column. Directly in front stood an
+opening or door. Bordering this was a framework of brick-like
+squares or tiles, black, and ornamented with white figures.
+
+"Just like pottery," said Alan, noticing the true geometrical design
+and the still cruder outlines of animals.
+
+"Look," exclaimed Ned, pointing to the top of the door.
+
+Here, the small tiles were replaced with a large square of black
+tile, in the center of which shone a dull yellow radiating design.
+
+"A symbol of the sun," explained Alan, "and of gold!" he added
+excitedly.
+
+"Then it certainly is our secret city," said Ned.
+
+As he said this he was busy with his knife, digging at the
+glistening white bits with which the column was coated. Finally one
+came off. It fell into his hand and the back of it came into view.
+
+The two boys broke out in an exclamation of delight. The protected
+portion of the piece was a deep sky blue.
+
+"The Turquoise Temple!" they both cried together. "Hurrah!"
+
+When night came again Ned and Alan were almost too excited for rest
+or sleep. Nor did they taste food again until the dust of the ruins
+warned them temporarily to abandon their search. To walk into a
+treasure house that the daring adventurers of two races had
+overlooked for three hundred years was enough to turn the heads of
+any two boys.
+
+The "Doorway of the Sun" as Alan called it, led into a chamber about
+fifteen feet square. The walls of this were lined with smooth clay
+squares of black tile, undecorated. Eight feet above the floor,
+which was also of clay tile and half buried under sand, rose a
+ceiling of arched stones. There was no opening in this, but steps
+on the outside of the temple and in the rear led to a chamber above,
+in the front of which, and also facing the sun, was another opening
+about two feet from the floor. In front of this window was a stone
+bench or altar. The meaning of it the boys did not know. This room
+was barren of either decoration or utensil and it was half full of
+the debris of what had apparently been another arched stone roof.
+Only the front or eastern side of the structure was coated with the
+precious turquoise; the other sides of the column were of plain,
+fairly well fitted, mortarless stone blocks.
+
+
+
+
+CHAPTER XXVIII
+
+THE COLLAPSE OF THE CIBOLA
+
+
+An opening in the paved court in the rear of the Temple, half filled
+with drifted sand, led into a "khiva" or secret religious council
+chamber beneath. Herein the young adventurers discovered their
+wonderland and the reward for all their labors.
+
+Hastily returning to the balloon, they procured candles and
+improvised scoops out of the sides of the tin emergency ration case
+obtained from the Arrow. Major Honeywell had warned the boys that
+the floors of all closed chambers of this sort were covered with the
+accumulated dust of ages.
+
+The first examination of the "khiva" resulted in disappointment.
+The immediate impression that the boys received was one of cave-like
+barrenness. In the half-light only a gray monotony met the eye.
+Yet under this ghostlike pall, forms soon began to appear. In the
+center of the chamber stood what was apparently an altar. In spite
+of its burden of dust an elevation could be seen about eight inches
+high and seven feet in diameter, on which was a boxlike structure
+about three feet square and four feet high. On top of this was a
+dust-covered figure. Beyond, in the deepest gloom, the mouths of
+four radiating tunnels leading still further into the ground could
+be seen. The roof was supported by irregular round columns,
+apparently of wood, arranged in two circles.
+
+Before beginning an exploration of the chamber the boys decided to
+ascertain the depth of the dust covering the floor, into which they
+had already sunk over their shoe tops. This was stifling work, for
+the soft powder ran back as fast as it was dug away. A half hour at
+least was consumed in reaching the bard surface beneath. The
+coating of dust was nearly three feet deep.
+
+As Ned climbed out of the little excavation Alan held the candle
+down. To the astonishment of the boys a beautiful blue sheen met
+their gaze.
+
+"Turquoise flooring!" shouted Ned.
+
+It was true. The entire "khiva," so far as the boys subsequently
+uncovered its floor, was a crude mosaic of the most perfect
+turquoise, the pieces, varying in size, being laid in a lime-like
+cement.
+
+A general survey of the room and its connecting tunnels showed that
+each radiating arm led, with about twenty feet of passageway, into a
+smaller room. In each of these rooms were nine column placed in a
+rectangle. The main chamber was circular in form, forty-eight feet
+in diameter, and the smaller apartments were twenty-four feet
+square.
+
+Ned while at work examining the floor, suddenly ceased and rushed to
+one of the columns.
+
+"You remember," he exclaimed, "the Spaniard said these columns were
+of gold and silver."
+
+But in this the ancient record was wrong. The inner six supports
+were painted a faded yellow and the second row, twelve in number,
+was colored red, as the boys discovered later when they brushed and
+cleaned some of them. Around each of the inner columns, however,
+there were two metal bands about two inches wide and thirty inches
+apart. The lower ones were six feet from the floor. They were of
+heavy gold with loops or hooks extending from each side, as if
+festoons or connecting bands had once extended from pillar to
+pillar.
+
+"Not a bad substitute!" exclaimed Ned.
+
+The second line of twelve columns had similar rings of silver, as
+the boys discovered in good time. The movable contents of the room
+were not easily examined, as each object on the floor was buried
+under a mound of heavy, suffocating dust. Bats had made the place
+an undisturbed refuge, and the repulsive flutter of these creatures
+was disconcerting.
+
+A preliminary examination of the four lateral passages and the rooms
+at their far end showed that these were probably store rooms,
+excepting the one on the east side. Here, on shelves, fixed on
+columns or posts similar to the colored supports in the principal
+chamber, were eight oblong forms. Even the dust and refuse could
+not disguise the nature of these--they were unmistakably mummies,
+the embalmed bodies of either chiefs or priests. At the head and
+foot of each were various dust covered receptacles and utensils.
+
+The afternoon was too short for the boys to accomplish the removal
+of anything.
+
+"I feel like a grave robber," panted Alan, soberly, as the two boys
+clambered out into the fresh air, finding, to their surprise, that
+it was already night.
+
+"Well, I don't," said Ned. "These things are so old that they seem
+to belong to Time itself. I feel more like a gold miner who has at
+last struck a rich vein--and it's our vein."
+
+But, as so often happens, ill luck came close on good fortune. The
+first glance of the young aeronauts at the camp and the Cibola was
+enough to chill their new happiness. The big gas bag had settled so
+low that it half concealed the car, which was resting flat on the
+ground. The buoyancy of the air ship was gone. Without more gas
+the Cibola could not make another flight. It was a severe blow to
+Ned and Alan; but they met the issue squarely.
+
+"There is no use in worrying," said Ned, finally, when they realized
+the exact situation, "and we've got to make the best of it.
+Besides," he said, laughing, "we are not ready to go."
+
+"That's right," replied Alan, thinking of the yet unexamined
+contents of the Treasure Temple, "and when we are ready I guess
+we'll be no worse off than Bob and Elmer. I suppose we can manage
+the one hundred foot descent some way."
+
+Ned pointed to the hundreds of yards of net cordage.
+
+"Right," exclaimed Alan, "that'll be easy--a rope ladder."
+
+It was almost dark and the boys were covered with the penetrating
+grime of the long undisturbed "khiva." A meager wash up and supper
+and rest were in order. But Ned said:
+
+"By morning the Cibola will be in collapse. It is a valuable
+machine, and it ought not be left out here on this point unprotected
+from the seasons. We shall probably never see it again, but while
+we can move it let's tow it over in front of the temple and put the
+bag and engine and instruments in the protected room."
+
+It was not a difficult task. With no great effort the car was half
+carried and half dragged down the slope and then to the clearing in
+the pine grove where the boys soon made a new camp. To complete
+their work the big bag of the balloon was untied from the car and
+drawn, half inflated, into the pathway leading to the temple door.
+Then, with no small regret, the boys opened the escape valve, and in
+a few minutes the collapsed Cibola was stretched like the cast off
+skin of a snake along the sandy pathway, ready to be rolled up and
+compactly stored away.
+
+
+
+
+CHAPTER XXIX
+
+THE GOLDEN EAGLE OF THE AZTECS
+
+
+In the morning the boys went at their task with renewed vigor.
+Inventory was first taken of the stores and provisions. There was
+enough food for about six days, if used with care. Of water there
+was a supply apparently for a little longer period. But the choking
+dust of the "khiva" made bathing almost a necessity, and, used in
+this way, even sparingly, the supply would not last over two days.
+
+"No more baths until we go down into the valley," ordered Ned.
+"Cleanliness would be a comfort, but we'll have to be uncomfortable."
+
+Permanent camp was made in the cabin of the dirigible. In arranging
+this all the machinery, the engine, the blower, the dynamo, the
+reconverter and the aeroplanes, the rudder and the propeller were
+unmounted, and the smaller articles made ready for storing in the
+temple entrance. There were four casks of gasoline left unused. As
+these were being carried to the temple Ned suddenly exclaimed:
+
+"Why not rig up the engine and dynamo and use an electric light down
+in our cave of Mystery."
+
+"Good," answered Alan, "and while we are at it, why not hook up the
+balloonet blower with the engine and get fresh air?"
+
+The stowing away of the machinery, the packing of the gas bag and
+the setting up of the engine and dynamo and blower afforded plenty
+of work until noon; and then, while the trusty little engine was
+pumping volumes of good sweet air into the hot, almost suffocating
+chamber below ground, the boys had luncheon.
+
+Then began the real exhumation of the long buried articles in the
+secret religious chamber of the almost forgotten race. As
+revelation succeeded revelation in the next two days the paralyzing
+wonder that first came to Ned and Alan was succeeded by the dullness
+of fatigue. At intervals of not more than an hour they came above
+ground for fresh air. The absence of water soon converted them into
+bronze-like human statues. They could feel that their lungs were
+becoming clogged with the almost impalpable dust. But they
+persevered. The prize was too rich to be abandoned because of mere
+physical discomfort.
+
+By means of the wired drag rope the powerful incandescent light was
+carried to all the chambers. And one after another, as the blower
+gave the boys air and helped sweep away the clouds of dust, the
+remains which had lain buried for over three centuries were
+uncovered and brought above ground.
+
+Of the pottery itself, vases, jars, and religious ceremonial
+utensils, perfect in shape and displaying ornamentation that would
+have delighted Major Honeywell, the excavators could take little
+note. After removing the twelve gold hoops or bands from the
+supporting columns and twenty similar silver rings from the second
+row of pillars, the boys penetrated the elevation in the center of
+the "khiva."
+
+As the end of the blower pipe was directed against this square
+column, the sediment of centuries disappeared. Then the brilliantly
+penetrating glare of the reflected electric light fell on the
+elevation and both boys burst out in an exclamation of amazement.
+
+
+On what had been a ceremonial dais stood the treasure of the secret
+city of Cibola--an image of the sacred Golden Eagle of the Aztecs.
+The revered bird of the Aztecs stood upright, its extended head
+peering east. The body of this aboriginal work of art, crude in
+form, was of massive silver. And to it were attached overlapping
+plates of gold in the similitude of feathers. The unfolded wings
+were also of gold. The head, beak and talons were of gold, and the
+eyes were two polished bits of quartz. The idol, for such no doubt
+it was, stood forty inches in height and weighed about three hundred
+pounds.
+
+The base on which the precious eagle stood was completely covered
+with the deepest blue turquoise. At its foot and covering the dais
+were the crumbled traces of many articles of cloth, feathers, bits
+of wood and pottery, and the like, all, no doubt, fragments of
+priestly utensils of worship. The most ornate and best preserved of
+these was a large flat bowl covered on the inside with skillfully
+cut mother-of-pearl. This was still iridescently beautiful, and the
+more striking because its milk white exterior was unmarked by
+decoration.
+
+Each mummy, when hauled into the open air and examined, gave more
+positive proof of the riches that had been collected in this sacred
+retreat. The funeral bowls placed at the feet of the bodies varied
+in form and material. Some of these were of plain black and white
+pottery, others were coated with gold, silver, or mother-of-pearl.
+The bowls apparently had once contained food. In all there were
+two golden bowls, four of silver, one of pearl and one of pottery.
+
+Each mummy was wound with as much care as was ever bestowed on the
+Egyptian royal dead. The woven wrappings were coated with pitch and
+beneath them were colored cotton cloths, affording proof of a high
+civilization. The richest treasures of the dead were the
+breastplates and necklaces found on each. These astounded the young
+investigators.
+
+These plates and beads had been strung on deer sinews, which, not
+having been protected by pitch, were now only lines of dust. But,
+lying on the breast of each there was invariably a "body scraper,"
+(as Major Honeywell afterwards termed them) of gold, silver or
+mother-of-pearl. Mother-of-pearl discs were the commonest neck
+decoration. Of these the boys discovered four.
+
+On three of the bodies were pierced pearl bead necklaces. On the
+most elaborately wrapped figure, that of a head priest or high
+chief, came the crowning discovery. This was a necklace of pierced
+amethysts. And on the breast of this figure was a flat plate of
+gold with sixteen radiating points, each of these terminating in a
+large luminous unpierced and polished amethyst.
+
+About the waist of this shriveled figure were the remains of a
+jeweled belt. The foundation or back of this had dissolved into
+dust, but careful unwrapping of the cerements revealed the priceless
+ornamentation. This decoration was of alternating squares of
+mother-of-pearl, in each of which glistened a perfect amethyst, and
+of matchless turquoise squares set with great pearls.
+
+
+
+
+CHAPTER XXX
+
+A QUARTER OF A TON OF TREASURE
+
+
+It was impossible for the boys even to venture an estimate on the
+value of the immense mine of turquoise, although they realized that
+the increasing scarcity of the jewel made the beautiful and unique
+specimens everywhere about them worth a great deal of money. Nor
+had they any idea of the value of the mother-of-pearl bowls, nor of
+the hundreds of beautiful and unique ceremonial and funeral urns and
+vases. Least of all, could they put even an approximate price on
+the amethyst and pearl necklaces. Even their most sanguine hopes of
+discovering the hidden city of Cibola had not led the adventurers to
+investigate the current prices of precious stones.
+
+Knowing, however, what the prices of gold and silver were, they
+could form some estimate of the worth of this part of the treasure.
+
+By comparison with the known weights of certain articles in the car
+the two boys made the following list of metal pieces discovered:
+
+GOLD POUNDS
+
+Twelve bands. Weight each 2 lbs. I oz. 26
+Two bowls. Weight each 6 lbs 12
+Two "body-scrapers." Weight each 9 oz 1 1/2
+Wings, head and talons of Sacred Eagle 82
+Breastplate 3
+Radiating sun over entrance 12
+
+Total, 136 1/2, or 1,638 ounces.
+
+SILVER POUNDS
+
+Twenty-four bands. Weight each I lb. 8 oz 40
+Four bowls. Weight each 5 lbs 20
+Four "body-scrapers." Weight 10 oz.. 3 1/3
+Body of Sacred Eagle. Weight 218
+Ninety-six miscellaneous rings, bands,
+ anklets and wristlets, many set with
+ mother-of-pearl and turquoise 16 1/3
+
+Total, 297 2/3, or 3,580 ounces.
+
+
+The market value of these precious metals was easily computed. The
+silver at sixty cents an ounce was worth $2,148. The more valuable
+gold, at twenty dollars an ounce, was worth $32,760. Together, the
+484 pounds were worth $34,908.
+
+"And one-third of that," said Ned with a smile--almost discernible
+beneath his dust--begrimed face, "is nearly $12,000. And that is
+$6,000 for each of us."
+
+"But how about the amethysts and pearls?" said Alan.
+
+"I suppose," answered Ned, "that they are worth a great deal more,
+but I don't know. I should think that those that have no holes in
+them would be very valuable."
+
+All this figuring was intensely interesting, but the boys, as the
+revelation progressed, knew that they were now facing a new problem.
+They could not possibly carry that gold and silver, to say nothing
+of even a portion of the exquisite mother-of-pearl bowls or the
+finest samples of the turquoise. When, in the end, nearly a quarter
+of a ton of the metal treasure alone lay in a heap in the corner of
+the temple vestibule they could come to but one conclusion.
+
+This portion of the treasure would have to be removed at another
+time.
+
+"It has lain here undisturbed for over three hundred years," said
+Ned hopefully, though sadly, "and we'll have to take a chance that
+it can be left a while longer."
+
+Sorrowfully enough Alan agreed. It was to be no easy work getting
+out of the wilderness, and food must be carried. That might be more
+precious to them than gold before they saw a railroad again. The
+boys agreed to take at noon the next day the exact latitude and
+longitude of the mesa. The latitude, on one slip of paper, was to
+be carried by one boy and the longitude, on another piece, was to be
+in the possession of the other. This was a precaution against
+accidental revelation of the treasure mesa.
+
+The set jewels were removed. There were two hundred and ninety-four
+pierced pearls and ninety-eight pierced amethysts. Among the whole
+gems, eighteen magnificent pearls were extracted from the jeweled
+belt. Eighteen unpierced amethysts were also taken from the
+alternating turquoise squares of the belt and sixteen magnificent
+amethysts from the gold breastplate.
+
+It was then that the sewing kit supplied by Alan's sister Mary came
+into service. A small piece of aluminum waterproof silk cabin
+covering was converted into two flat bags and in these the stones,
+equally divided, were enclosed and concealed under the clothing and
+beneath the right arm of each lad. In addition, each boy took half
+of the mother-of-pearl and turquoise belt plates as the finest
+specimens of each material.
+
+"And to show that there is gold too," suggested Alan, "we might as
+well take along, these gold 'scrapers,' which won't bother us much,"
+So these two pieces were strung on cords and suspended about the
+necks of the young treasure seekers.
+
+"And to-morrow," exclaimed Ned joyfully when all this was done,
+"we'll get down from here and get a bath."
+
+"Amen," added Alan earnestly.
+
+Until it was twelve o'clock, the time to take their observation, the
+boys spent the next morning in last preparations and making
+everything shipshape. The framework of the car was left intact, but
+weighted by stones to prevent injury by the wind. Everything
+movable was stored in the entrance room of the temple, including
+three and one-half cans of gasoline. The engine was oiled and
+covered with blankets. Underneath the smoothly folded balloon, in
+the folds of which dry sand had been liberally sprinkled to prevent
+possible adhesions of the varnish, lay nearly thirty-five thousand
+dollars' worth of curiously wrought gold and silver. This was first
+completely covered with sand.
+
+The two provision packs for the retreat to civilization had been
+carefully arranged. How long the journey might take the, could not
+estimate. They had decided to their way east, in hope of falling in
+with Elmer and Bob, and this meant the crossing of at least two
+mountain ranges and thirty miles of barren foothills to Mount
+Wilson. Then, if they turned south, they would traverse eighty-five
+miles of sandy plain in which water was infrequent.
+
+Their own provisions were exhausted. What they now depended on was
+the emergency case secured from the Arrow. This supply was intended
+to be enough for two men for two weeks.
+
+"It certainly ought not take us that long,"' complained Alan. "Why
+not leave half the supply and take a little gold?"
+
+But Ned was obdurate. He explained that they might fall in with the
+other boys, and that if they did Elmer and Bob might be wholly out
+of supplies.
+
+"We can come back if we get out in good shape," explained Ned, "and
+if we don't get out what'll be the use of a back load of gold?"
+
+That settled it. The food packs were made up of the following
+supplies: Flour, 12 lbs; corn meal, 5 lbs; beans, 5 lbs; bacon, 7 1/2
+lbs; rice, 5 lbs; oatmeal, 2 lbs; baking powder, 1/2 lb; coffee, I
+lb; tea, 1/2 lb; sugar, 5 lbs; lard, 2 1/2 lbs; salt, 1/2 lb; pepper,
+1/8 lb. Each provision pack weighed twenty-one pounds. In addition
+there was an aluminum frying pan, a coffee pot and two aluminum
+plates. A water canteen, a blanket, a revolver and belt of
+ammunition and a knife apiece completed the equipment. Alan carried
+in addition the "snake bite" case, the compass and small hatchet,
+and Ned the money belt containing over five hundred dollars in gold.
+
+The sealed glass tubes of matches were divided between the two boys
+and then, as it was noon, the sextant that Ned had been so careful
+to bring with them was used for the first and last time. The
+observation made and noted, and the record of it divided as planned,
+Ned and Alan were ready to begin their attempt to make their way out
+of the rock-bound wilderness. With provisions, water, blanket and
+arms each lad was carrying about thirty-five pounds.
+
+"Would you still like a few pounds of Aztec treasure?" laughed Ned
+as they stood with packs adjusted.
+
+"I should say not," retorted Alan; "I'm satisfied."
+
+The method of lowering themselves from the hole in the face of the
+cliff to the ground, one hundred feet beneath, had been worked out
+in detail and the apparatus made in the evenings by the light of
+their camp fire. And early that morning Alan had carried the long
+rope ladder down the chasm and to the mouth of the tunnel. Now, in
+addition to their packs, the two boys carried between them a section
+of one of the pine trees, about six feet long.
+
+As they stood, ready to leave, Ned raised his cap.
+
+"Good bye, old Cibola," he said with moisture in his eyes, "until we
+meet again, if ever."
+
+"If ever?" added Alan quickly with as much gaiety as he could
+summon. "You don't think we'll ever let anyone else lift that
+little pile?" and he pointed to the well filled entrance room of the
+temple.
+
+"No," answered Ned, soberly, "if we have as good luck on the land as
+we had in the air."
+
+Ned and Alan meant to reach the earth by means of a rope ladder.
+This they had constructed from the stout Italian hemp suspension
+cords of the Cibola. These ropes, each thirty feet in length, were
+knotted and then doubled to insure strength. For the last
+twenty-five feet at the bottom the landing ladder of the balloon was
+used. The rungs, two feet apart, were of pine from a felled tree,
+and were thirty-eight in number.
+
+For anchorage, the six-foot length of tree was dragged to the mouth
+of the tunnel and, five feet from the opening, wedged between the
+floor and roof of the tunnel, slightly inclined forward. The strain
+on the bottom would thus only fix the supporting section more firmly
+in place. From the bottom of the pine shaft a loop of four of the
+suspension cords reached just out of the tunnel opening. To this
+loop the top rang of the ladder was tied, with a separate
+hundred-foot length of cord. After the ladder had been made firm
+with a running slip knot the hundred-foot length of cord was dropped
+to the ground.
+
+This arrangement had been provided in order that the rope ladder
+might be removed after the descent. By a jerk of the cord the slip
+knot would be loosened and the ladder, released, would fall of its
+own weight. Another length of rope had been prepared, this one
+somewhat over a hundred feet long and also doubled for strength.
+This was for the lowering of the packs and other articles by one of
+the boys after the other had descended. To insure its free running
+and to prevent its wearing through on the edge of the cliff, a six
+inch section of the pine tree had been prepared, flattened on one
+side and having a wide smooth groove in the top. This, attached to
+a short length of rope, which was made fast with the ladder loop to
+the upright shaft in the tunnel, was fixed on the verge of the
+opening.
+
+Finally everything had been arranged and made fast. Each of the two
+boys insisted that he should go down first. To solve the dispute,
+they cast lots and the risk of testing the rope fell to Ned.
+Slipping off his shoes and socks, which he hung about his neck, he
+sprang to the ladder. Alan hung over the edge and watched him with
+apprehension, but Ned, feeling his way carefully, was soon on the
+ground.
+
+His shout was the signal to begin the work of lowering the packs.
+And down they came, one after another; provisions, revolvers,
+blankets, water bottles, and even the money belt, for Ned had made
+himself as light as possible for his descent.
+
+At last it was Alan's turn. The last load had descended, the
+lowering line had been released, drawn up and stowed away. The slip
+knot was examined anew and then Alan followed Ned down the slender,
+fragile swaying rope ladder. When he had reached the ground by
+Ned's side and the strain was over, the boys shook hands jubilantly.
+
+"--And now," shouted Ned with a laugh, "last chance! If you want to
+go back for a new load say so before it is too late."
+
+Alan, exhausted with the climb, shook his head.
+
+"Then stand from under," cried Ned.
+
+As he jerked the slip knot cord the boys sprang aside and the long
+ladder, wriggling, crashed at their feet.
+
+The only means of reaching the towering elevation had been removed
+and the only visible sign of their brief occupancy of the secret
+mesa had been destroyed.
+
+
+
+
+CHAPTER XXXI
+
+AN ADVENTURE WITH THE NAVAJOS
+
+
+Three days later, Ned Napier and Alan Hope, worn and almost
+exhausted with the steady climb and descent of countless rocky
+heights, made their camp for the night at the foot of a rugged
+slope. Their shoes were torn so that a protection of rags was
+necessary. The hot and pitiless sun had seemingly dried up their
+boyish spirits. Silent with fatigue, having plodded steadily
+forward since sunrise, they threw themselves on the sand.
+
+The young adventurers were headed straight for the east. And still
+the last range of mountains was beyond them. Led by the compass,
+they held to their course, sometimes passing miles out of their path
+to avoid some inaccessible mesa, but more often scaling ragged and
+tiresome heights.
+
+Eating had now become a matter of form and necessity. There was no
+longer the keen joy in making camp. During the three days the boys
+had seen no living object except birds, rabbits, many deer and two
+bears, all of which they had left unmolested in their eagerness to
+press forward. But at noon on this day Alan, having occasion to
+glance backwards, was positive that he saw a human head. Whether
+white man or Indian he could not determine. The incident gave the
+lads no little, concern, but as no further sign of a human being was
+seen that day they finally forgot the matter.
+
+That night, after making tea and taking a little more pains than
+usual with their supper in an effort to revive their spirits as well
+as their tired bodies, Ned and Alan spread their blankets at the
+edge of a pine grove. Almost before it was dark they were both
+sound asleep.
+
+Some hours later Alan awoke with the instant consciousness of an
+unusual sound. Motionless and straining his ears, he heard deep
+breathing just behind him. A new moon was just sinking below the
+buttes on the far side of the little valley in which they had
+stopped for rest, but under the pines the shadows were deep. He
+knew that danger was near and he did not move. In another moment he
+felt a soft hand on his waist, as swift and as silent as a snake,
+and he knew that the hand was extracting his revolver.
+
+Then, from his half-opened eyes, he saw a figure crouching over his
+chum just opposite. Some one no doubt was also removing Ned's
+weapon. Then there was the pressure of stealthy footsteps on the
+pine needles and Alan moved his head until he could see two
+indistinct forms moving from the shadows of the timber across the
+open space to the dying embers of their little fire. There he could
+easily discern five or six figures. He was about to put his hand on
+Ned's face to awaken him gently when he saw the entire group coming
+directly toward their sleeping place. Their movements now revealed
+plainly that they were Indians.
+
+With cold beads of perspiration covering his body Alan again
+pretended sleep. It was now apparent that they had been followed,
+and, no doubt, by Navajos. Perhaps this was the end of their
+toilsome retreat. With visions of death presenting themselves, he
+wondered again whether he ought to arouse Ned. Then he realized the
+futility of such action. As the moccasined feet drew near Alan
+could read death in each approaching sound. But at the edge of the
+trees there was another pause, and then he knew that the Indians had
+scattered.
+
+Straining every muscle in an effort to breathe naturally, like one
+asleep, the boy counted the seconds while he waited for the clutch
+of a savage hand. And as the moment passed and the attack did not
+come he tried to speculate on what the strangers were doing. A
+guttural half exclamation soon allowed him a quick breath of
+temporary relief. The Indians were only after their supplies.
+
+The savages had found the half-concealed packs of the two boys.
+Alan knew this by the location of the sounds that now came to him,
+and then, as the prowlers withdrew again into the open and the faint
+moonlight, it could be seen that they were bearing all the
+belongings of the two lads. For perhaps ten minutes Alan lay
+without moving and watched the Indians. He could make out that they
+were hastily looking over the packs and dividing what yet remained
+among themselves. Then ponies were led to the place of the camp
+fire and the members of the band quickly threw themselves on their
+animals and disappeared into the night.
+
+Almost paralyzed with the knowledge of what this meant Alan now
+softly put his hand on Ned's face:
+
+"Are you awake?" came instantly from Ned.
+
+"Are you?" retorted Alan in surprise.
+
+"Yes," whispered Ned, "I saw it all. But I didn't move, because I
+was afraid of arousing you."
+
+"Here, too," exclaimed Alan. "Did you feel them take your
+revolver?"
+
+Ned's band flew to his belt.
+
+"Is yours gone too? I saw them when they came up from the fire.
+But you did right to keep still. If we had moved I expect we'd have
+had our throats cut."
+
+"That was one of them I saw to-day," added Alan, "and I guess we're
+lucky to be alive."
+
+"Yes," added Ned rising to his feet, "we are. They are satisfied, I
+suppose, to let us starve."
+
+The prospect was a trying one. If the range behind them was the one
+they hoped it was, there was only one more valley between its summit
+and the outer ridge of the Tunit Chas. If they could reach this
+ridge they believed they might see Mount Wilson's peak. But even
+that meant another thirty miles to the scene of the attack on Buck's
+camp on the banks of the Chusco. And from that place it was
+eighty-five miles to a railroad and help!
+
+The boys sat in the edge of the pines as the new moon disappeared,
+leaving them in utter darkness, and tried desperately to encourage
+each other. Both had the grit to set themselves stoutly to the
+apparently hopeless task. Without food or firearms and possibly
+without water, they knew they would find the task gigantic. But
+nothing was to be gained by waiting for starvation and death in the
+wilderness, and their decision was to do what they could, to try the
+almost impossible, and if they failed to fail with their faces
+toward the east.
+
+"Why not start now?" urged Alan. "Let's use what strength we have."
+
+But Ned showed him the folly of this.
+
+"A night's rest will enable us to make better time to-morrow. And
+besides, we can't make headway when we can't follow the compass."
+
+Retiring a little further into the woods the boys composed
+themselves again and before long were once more fast asleep.
+
+
+
+
+CHAPTER XXXII
+
+ALAN SUCCUMBS TO EXHAUSTION
+
+
+The boys were up at dawn. Not an article had the marauders left but
+the two water canteens which had fortunately been left hanging from
+the low branches of a pine. It was useless to look for more--there
+was nothing more to be found.
+
+"Anyway," laughed Ned, "it leaves us in light marching order and we
+can make better time. I'm glad we had a good supper."
+
+As no breakfast was in sight the two boys filled the water bottles
+at the creek in the valley, and at five o'clock, taking their
+bearings due east, Ned and Alan struck upwards through the pine
+woods. It was a not unpleasant climb while the boys were fresh, but
+as the slope grew more precipitous the work began to tell. At one
+o'clock the crest was reached.
+
+"How would you like a piece of broiled bacon, some pancakes and a
+cup of coffee, Ned?" asked Alan as they paused to rest.
+
+"In the middle of the day and on the top of a mountain I always
+prefer plain water," laughed Ned in reply. "Here's to you!"
+
+With a big drink from the lukewarm canteens the boys did not pause
+long.
+
+"To-night," continued Ned, "we ought to sleep high up in the
+foothills over there."
+
+With that inspiration the sore-footed and jaded lads made good time
+going down the slope. Then another rivulet was encountered, in
+which they bathed and by which they rested a spell. Alan would have
+been glad to pass the night here, but Ned urged him on, and as night
+fell again the hungry, exhausted boys found themselves far up on the
+new slope. Then they slept again, restlessly and on the rocky
+ground, for they had abandoned their blankets.
+
+The boys did not wait for daylight. In the half dawn they were
+afoot.
+
+"Take another hitch in your belt, chum, and don't think of the
+Placida." laughed Ned. "We'll make it all right, somehow."
+
+Stiff in limb, their feet twitching with the pain of blisters, Ned
+and Alan toiled slowly through the last of the pines and out into
+the rocky higher slopes of the range. It was like climbing an
+upright wall, Alan said, but the pain of going on was less than the
+despair of giving up. A little after six o'clock Ned, ahead, pulled
+himself breathless to the highest point.
+
+Alan stopped a little below and waited in anxiety. Before he could
+ask whether it was the last ridge, Ned's voice broke out into a
+shout.
+
+"Come on, old man, we're all right. There's old Wilson, the
+grandest mountain peak in the world. Hurrah for Mount Wilson!"
+
+But there was no echo to his exclamation. Poor Alan, succumbing to
+pain and exhaustion, had sunk insensible to the ground. In another
+moment Ned was at his chum's side. Forcing some water between
+Alan's lips and bathing his face with some more of the precious
+liquid, Ned soon brought him back to consciousness. Alan sprang up
+in chagrin, and with tears in his eyes insisted that he had only
+stumbled and fallen. But Ned knew the truth. His friend's bright
+eyes and feverish skin told that his condition was grave.
+ The unseen tears came to Ned's eyes, for it was at least thirty
+miles to more water and the plains. And should they even reach the
+Chusco, he could see only death in the desert.
+
+"You'll feel better in the cool of the woods down there," said Ned
+gently, "and maybe we can kill a rabbit. Hurrah, come on, Alan!
+Brace up. It's all down hill, now. Here's for the woods and
+broiled rabbit!"
+
+In a new spurt of life another start was made and the two chums set
+out down the slope. In one of Ned's hands was a rock. It was to be
+the death warrant of any small animal, and his eyes were busy
+examining each sheltered rocky nook and bush. Suddenly a feverish
+hand caught his.
+
+"Look," whispered Alan.
+
+Ned's eyes followed his chum's gaze.
+
+It was a spiral of thin smoke in the trees below.
+
+With a shout, Ned sprang forward. Then he turned. Alan was
+standing still. Ned's heart grew cold:
+
+"See the smoke," Alan was repeating, "see the nice smoke. Maybe
+it's a house on fire."
+
+His friend was delirious. Ned flew to his side once more and again
+his touch revived the exhausted boy. Almost five days of wandering
+and the exhausting toil on the mesa had proved too much for the more
+delicate Alan, and Ned realized with sickening horror that the
+situation was critical.
+
+"I'm all right, Ned," answered Alan when his chum was once more with
+him; "just a little lightheaded. But that's all."
+
+What was to be done? The smoke might be that of a forest fire. And
+it might mean Indians. But even an enemy is welcome when starvation
+and death confronts one. Almost at the end of his own resources,
+the determined Ned forced himself into a last effort. He used no
+words of persuasion, for Alan allowed Ned to take his hand, and
+thus, silently and slowly, the two moved forward again. Perhaps
+another half mile was made between rocks and down gullies and then
+Alan exclaimed pitifully:
+
+"It's no use, Ned, I can't, I can't. My feet." Burying his
+fevered face in his hands, the boy wept, partly in pain and partly
+because he knew that he was holding back his chum.
+
+At such periods Ned Napier was at his best. With kind words he
+sought to encourage his friend. He used the little water left to
+bathe Alan's face, and the last of his shirt in binding anew his
+friend's bleeding feet. He tried to joke and speculated on the
+possibilities of the smoke beyond them, but it was without avail.
+Poor Alan could not rise again. The fever of exhaustion was on him
+and with a last appeal to Ned to leave him the boy threw himself on
+the ground and fainted away.
+
+There was no doubt now as to what was to be done. Unless he could
+bring help to his friend in a short time Ned knew it would mean
+death. And that meant death for both, for young Napier would never
+abandon his friend. Like a drunken man Ned turned and stumbled
+forward.
+
+
+
+
+CHAPTER XXXIII
+
+A FORLORN DASH FOR HELP
+
+
+Am hour later Alan Hope, carried by the faithful Elmer Grissom and
+the jovial Bob Russell, was laid gently on a blanket by the fire
+whose smoke had attracted the attention of the ragged, worn
+wanderers. Not until the sun had set did the exhausted lad open his
+eyes again. But water and food had been forced through his lips and
+when reason came back strength was not far behind.
+
+Ned sat by his chum's side all day, bathing his face and making him
+as comfortable as possible; from Elmer's medicine packet. A few
+mouthfuls of food had sufficed Ned. But that night, when Alan came
+again to his senses, the four boys held a thanksgiving about a
+cheerful fire and ate together. But it was no banquet.
+
+What had happened was soon repeated to the weak but happy Alan.
+Elmer and Bob had waited and watched for ten days, using their
+stores sparingly and ready always for the return of Ned and Alan.
+Two days they had seen the Cibola a speck in the sky far to the
+west, and had watched it from the little waterfall on the edge of
+the plateau. Then it disappeared and they never saw it again. This
+was three days after the boys departed from Camp Eagle.
+
+Husbanding their provisions as well as they could, they at last
+decided to start on their return to the outside world.
+
+This was two days before. The tent and the heavier articles were
+hidden in a cache. Their food had been reduced to a meager
+quantity. They had two pounds of bacon, six pounds of flour, two
+ounces of tea and a little over a pound of beans. In addition they
+had a half dozen bouillon tablets, a little salt, pepper and sugar,
+and a complete and unopened medicine packet in which were quinine,
+adhesive plaster, cotton, bandages, morphine, and other needed and
+compact drugs. With this light pack each boy had a rifle and a
+revolver, a few cooking utensils and a blanket.
+
+Elmer had his own water bottle, and Bob improvised two out of the
+empty baking powder can and a lard pail.
+
+Thus equipped, Camp Eagle was abandoned, and led by their compass
+Elmer and Bob had set out bravely for Mount Wilson and the Chusco.
+But it was with no small regret that they made their way up the long
+slope behind them and then across the valley beyond. But, fresh and
+strong of limb, they pushed forward and with Mount Wilson as a
+landmark made camp on the second night in the timber on the slope of
+the outer range.
+
+Never wholly despairing of meeting Ned and Alan again, the two boys
+were frugal both of their strength and their stores. The food they
+carried would have been sufficient for a healthy man for perhaps a
+week. They could not count on reaching civilization again within
+that time, even with good luck. That meant half rations at the
+best. But if accidents came and delay even half rations would be
+cut down. So, that night, in camp, there was no feasting. A little
+tea, and a cake of dough apiece made their supper; and then they
+slept.
+
+In the morning as they were about to breakfast and be off again Bob
+caught sight of a deer. A little jerked venison would not come
+amiss, he thought, and as the ammunition was plentiful he darted
+through the woods in pursuit. The fact that Bob was a poor hunter
+probably saved Alan's life. He was gone an hour and a half and when
+he returned it was after seven o'clock.
+
+The two boys had just extinguished their fire and were about to
+shoulder their packs when a well-known but strained call arrested
+them.
+
+"Camp ahoy?"
+
+It was their leader, Ned Napier, his cheeks sunken, and his body
+swaying from weakness, but cheery as of old, advancing slowly
+through the trees.
+
+Food and a night's rest restored Ned's strength. "And now, my
+friends," said he in the morning, "these bandages and a little food
+and good companionship have worked wonders. We are all ourselves
+again. But we can't stay here, pleasant--as it is. Alan ought not
+to travel for another day and then he ought to have some husky
+attendant. Bob, you are nominated for that job. Elmer and I will
+take a few pinches of tea, the soup tablets, one revolver and a
+rifle and--"
+
+"And what?" exclaimed Alan, suspicious of Ned's suggestion.
+
+"And," continued Ned, "We'll just dash on ahead and bring you some
+help."
+
+"No, siree," shouted Alan. "Do you think get back to Clarkeville,
+one hundred and fifteen miles or more, on six soup tablets? And for
+me? If you think you ought to go, all right. But you'll take half
+of the food."
+
+"Or more," interrupted Bob, "give us a little flour and salt and
+some matches. I reckon I can get a deer before night."
+
+But Ned convinced them in the end that he was right. He argued that
+each mile he and Elmer made in advance was nearer help. Alan must
+advance slowly.
+
+"All you've got to do," he explained to Bob and Alan, "is to reach
+the Chusco, where Elmer camped, and take care of yourselves for
+seven or eight days. And we'll be there to help you, unless
+something happens. You won't have much to eat but you'll have water
+and you have ammunition."
+
+And at seven o'clock that morning they parted. Just before the
+farewells Alan called Ned to one side and said:
+
+"Hadn't you better take my bag?" indicating the jewel case under his
+arm.
+
+"Why?" answered Ned.
+
+"Well, you know we may never see each other again."
+
+Ned took his chum's hand.
+
+"Alan," he said, "we were not born to lose ourselves in the woods,
+much less to die there. We'll meet again all right. Don't you have
+any fears on that point. But if we shouldn't, I won't care for
+amethysts or pearls. If I don't see you again it'll be because I'm
+beyond the need of those things."
+
+There were handshakes and cheering, good wishes, and the relief
+section was off.
+
+"Elmer," said Alan, after the two had been trailing through the
+trees Indian fashion some time, "it is daylight at four o'clock and
+dark at seven--that's fifteen hours. Can you walk two miles an
+hour?"
+
+"Sho'ly," smiled Elmer, showing his white teeth.
+
+"Well, that's thirty miles a day. If we could do that for four days
+we'd be in Clarkeville!"
+
+"Claikeville in fo' days it am den," echoed Elmer, "or bust."
+
+"We've got six soup tablets. If we dine on one at ten o'clock in
+the morning and one at seven o'clock in the evening we'll have
+regular meals for three days."
+
+"And de las' day we won't need none, we'll be in such a hurry,"
+added the colored boy, happy again in Ned's company.
+
+That was the spirit in which the expedition started. Late that
+afternoon they emerged from the timber and were on the sandy
+foothills where progress was faster. Ned's feet bothered him and he
+was in constant pain, but the adhesive plaster and cotton had been
+of the greatest help. There was no pause. The first day's schedule
+he was determined to make and at about eight o'clock the relief
+expedition gave a shout. The Chusco lay before them.
+
+A little fire, some tea and bouillon--made in the pan after the tea
+was consumed--and the two boys found a bed on the soft sand with no
+covering but the deep Mexican sky. At dawn they were up and away
+after a bath in the muddy river. Elmer was now the guide and he
+readily picked up Buck's old wagon trail. Sharp at ten o'clock a
+halt was made for breakfast, bouillon now without tea. Ned, his
+face a little more sunken and his legs a little more unsteady than
+the day before, was sitting on the ground resting his burning feet,
+when Elmer suddenly touched him on the shoulder, set the soup pan
+quickly on the sand and drew his revolver.
+
+Far down the trail a horseman was approaching. Behind him in the
+distance followed a wagon. What did this mean?
+
+"Well, whoever it is, we'll have the soup," said Ned.
+
+This consumed, Ned and his friend started forward.
+
+"If it's good luck we'll meet it sooner this way," said Ned, "if
+it's bad we'll know the worst quicker."
+
+But it was good luck. The rider soon galloped up and swung his wide
+hat in the air. It was Curt Bradley, the mayor of Clarkeville.
+
+
+
+
+CHAPTER XXXIV
+
+THE RESCUE
+
+
+They told Ned afterwards that he keeled over in the sand and fainted
+dead away, but he always insisted that he didn't faint, that he knew
+everything that was going on. Yet he did not hear a word of the
+long story told by Elmer. When he roused himself he was lying in
+the shade of the big freight wagon and a couple of cowboys were
+getting breakfast ready.
+
+Then Mayor Bradley explained his presence in that mysterious way in
+which bad news always travels friendly Indians had sent him word of
+the attack on Buck's outfit and of the death of the veteran
+plainsman. This news had just reached Clarkeville and Mayor Bradley
+had at once set out to find the body if possible, and assist those
+who escaped.
+
+Of course all speed was made toward the foothills and that evening
+Alan and Bob, the former only a shadow of the lively youngster who
+had left Clarkeville but two weeks before, were found and rescued.
+That night there was a new camp on the Chusco and meat and hot
+bread. The only shadow to dim the happiness of the rescued boys was
+the recollection of the murdered Buck.
+
+The return to Clarkeville was made by easy stages in four days, and
+even Alan was nearly his old self when that town was reached. One
+night's rest in real beds, with fresh linen from the baggage they
+had left behind them, and baths, removed the traces of privation and
+suffering. There was little more to detain Ned and Alan.
+
+A telegram was dispatched to Major Honeywell at Kansas City, where
+the boys and their patrons had agreed to meet. Then Ned's tool
+chest was forwarded by freight to Chicago. In company with Mayor
+Bradley Ned and Alan visited Mrs. Bourke, Buck's widow. Retaining
+enough to cover the costs of transportation to Kansas City he gave
+the widow what remained of his funds, nearly five hundred dollars,
+and all the heavy stores remaining in the corral.
+
+At midnight of that day four wide-awake and alert boys, neatly clad
+in summer suits, boarded the local train bound east for Albuquerque.
+The last hand they shook was that of Mayor Bradley.
+
+"Mr. Mayor," said Ned as he parted from his friend, "I'm sorry I
+can't tell you why we were here, or what we were doing. But you
+were our friend and we'll never forget you. Some day I'm going to
+show you how highly we regard you. And some day I hope I'll be able
+to tell you what our mission was."
+
+Three days later the quartette of boys sprang from the Limited in
+the Union depot at Kansas City. The parting had come. None of the
+boys knew what that meant until the last moment.
+
+"'Ned," said Bob Russell, once again in the field of his profession,
+"I've had many a strange assignment in my work and I expect to have
+many another, but I'll never have one like this. I've got the story
+of my life, but I haven't got yours. If the time ever comes when I
+can write it, when you are free to tell it, just remember your best
+friend, Bob Russell, reporter, Kansas City Comet."
+
+"Bob," answered Ned wringing his hand, "you have missed a good
+story. I'm sorry. It wasn't because you were not a good reporter.
+It was just our good luck. But if things work out the way I hope,
+I'm going to give you something better than a good story."
+
+"And," broke in Alan, "just want to say this: if chance ever throws
+adventures my way again I hope that the companions I share it with
+will always include Bob Russell."
+
+The details of how Ned and Alan, just one day late, kept their
+engagement with major Honeywell and Senor' Oje in the Coates House,
+and of the almost unbelievable report they made and the rich
+evidence of its genuineness that they submitted do not really belong
+in an account of the flight of the Cibola. Two things were done at
+once, however. A handsome gold watch was purchased and sent to
+Mayor Bradley with the compliments of Ned and Alan, and Senor Oje
+forwarded an additional check for a thousand dollars to Buck's
+widow.
+
+The report on the value of the stones carried from the treasure
+temple by the two boys was such that Senor Oje gave them his check
+for $25,000. Out of this each boy contributed part of his share
+toward a sum sufficient to give Elmer a business education. Finally
+the two boys bought a draft for a thousand dollars, payable to
+Robert Russell. With it went this note: "Please accept this as some
+slight compensation for the story you did not get."
+
+But in good time Bob Russell did get his story. For, otherwise,
+this narrative would never have been written.
+
+How it came about that Bob got his story; how the treasure left in
+the Turquoise Temple was finally lifted; how the young aeronauts in
+doing it battled successfully with a maelstrom in the clouds, were
+driven far out over the Pacific, cast away on a derelict and finally
+made an escape with their "sneering idol" by aeroplane into the
+wilds of Mexico, is a later and more remarkable chapter in the
+adventures of Ned Napier and Alan Hope, to be told in "The Air-Ship
+Boys Adrift, or Saved by an Aeroplane."

+Project Gutenberg eBooks 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 eBooks in compliance with any particular paper edition.
+
+We are now trying to release all our eBooks 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 eBooks 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 Web sites at:

+
+
+Those of you who want to download any eBook before announcement
+can get to them as follows, and just download by date. This is

+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 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.
