+CHAPTER I.--A MOUNTAIN MYSTERY.
+
+
+On a sizzling hot afternoon near the middle of August, in the year
+nineteen eleven, three boys dressed in the khaki uniform of the Boy
+Scouts of America stood on a lofty plateau near the British frontier,
+watching with anxious eyes the broken country to the south and west.
+
+"Nothing stirring yet!" Jack Bosworth said, turning to Pat Mack and
+Frank Shaw, his companions. "Ned and Jimmie may be in trouble somewhere.
+I wish we had waited and traveled with them."
+
+"Traveled with them!" repeated Frank Shaw. "We couldn't travel with
+them. We were fired--given the grand bounce--twenty-three sign. Ned
+seemed to want the space in the atmosphere we occupied at Missoula.
+Serve them good and right if they do get distributed over the scenery."
+
+"Never you mind about Ned Nestor and Jimmie McGraw," Pat Mack put in.
+"They can get along all right if someone isn't leading them by the hand.
+Suppose we fix up the camp and get ready for our eats?"
+
+The boys turned away from the lip of the caņon upon which they had been
+standing and busied themselves putting up shelter tents and unpacking
+provisions and camping tools, as they called their blankets and cooking
+vessels.
+
+They had passed the previous night in a sheltered valley lower down,
+sleeping on the ground, under the stars, and had breakfasted from the
+scanty stock of eatables carried in their haversacks. Early that morning
+a train of burros had landed their outfit at the end of a rough trail
+some distance below, and the boys, with long labor and patience, had
+carried it up to the plateau.
+
+The men in charge of the burros had of course volunteered to assist in
+the work of carrying the goods to the place selected for the camp, but
+their offers had been declined with thanks, for the Boy Scouts were
+determined that for the present no outsider should know the exact
+location of their temporary mountain home.
+
+Those who have read the previous books of this series[1] will not be at
+a loss to understand why the location of the camp in the Northwest was
+for a time to remain a secret, so far as possible. Ned Nestor, for whom
+those on the plateau were now waiting, had, some months before that hot
+August afternoon, enlisted in the Secret Service of the United States
+government.
+
+Accompanied by Frank Shaw, Jack Bosworth, Jimmie McGraw and others, he
+had seen active diplomatic service during the Mexican revolution, had
+unearthed a plot against the government in the Panana Canal Zone, and
+had rendered signal service in the Philippines, where he had assisted in
+preventing an armed revolt against the supremacy of the United States
+government.
+
+At the close of his service in the Philippines, he had been commissioned
+to investigate forest fire conditions in the Great Northwest. The boy
+had a wonderful native talent for detective work, and, besides, it was
+thought by the officials in charge of the matter that a party of Boy
+Scouts, camping and roving about in northern Idaho and Montana and in
+the southern sections of British Columbia, would be better able to size
+up the forest fire situation than a party of foresters or government
+secret service men.
+
+So Ned and his four chums had sailed away from Manila, reached San
+Francisco in due season, and, after receiving further instructions and
+arranging for supplies, had headed for the frontier. At Missoula,
+Montana, he had sent Frank, Jack and Pat on ahead, after giving them the
+exact location of the future encampment and arranging for the
+transportation of supplies.
+
+From the first there had been some mystery in the minds of the three
+concerning Ned's strange halt at Missoula. They could not understand why
+he had sent them on ahead of him, for he usually directed every detail
+of their journeyings. When questioned concerning this innovation, Ned
+had only laughed and told the boys to keep out of the jaws of wild
+animals and not get lost.
+
+"I'll be in camp almost as soon as you are," he had said, "and will take
+the first mountain meal with you."
+
+Yet the boys had reached the vicinity of the chosen location on the
+previous day, and Ned had not made his appearance. Naturally the boys
+were more than anxious about the safety of their leader.
+
+"Did Ned say anything to you while at Missoula, about an aeroplane?"
+Jack asked of Frank as they unpacked bacon and corn meal. "You know,
+before we left the Philippines," he went on, slicing the bacon for the
+coming repast, "the officials said we were to have a government
+aeroplane. I was just wondering if the thing would get here after we
+have no use for it."
+
+"He said nothing to me about the arrival of the aeroplane," Frank
+replied, "but I presume he knows when the government air machine will be
+on hand. It may be packed up at Missoula, for all we know," he added,
+"and Ned may have waited there for the purpose of getting it ready for
+flight."
+
+"What the dickens can we do with an aeroplane in this wilderness?"
+demanded Pat, wiping the sweat from his face. "We can't run around among
+the trees with it, can we? Nor yet we can't get gasoline up here to run
+it with. Anyway, I'm no friend to these airships."
+
+"When they travel with upholstered dining coaches in connection, and
+sleeping cars on behind," laughed Jack, "you'll think they're all to the
+good. If we can't chase around among the trees in an aeroplane," he
+continued, "we can sail over the forests and high peaks, can't we?
+Without something of the sort, it would take us about a thousand years
+to get a look-in at this wild country."
+
+"Well," Pat grumbled, "I only hope we won't get our necks broken falling
+out of the contraption. It may be all right to go up in one of the
+foolish things, but I think I'd rather take chances on going over
+Niagara Falls in a rain-water barrel."
+
+"I half believe he will come in the aeroplane," Frank said, shading his
+eyes with his hand and looking out to the south. "He wants to surprise
+us, I take it, and that is why he acted so mysteriously about the
+matter."
+
+"What about Jimmie?" demanded Pat, who would take almost any risk on
+water, but who was filled with horror the moment his feet left the solid
+earth. "He can't bring Jimmie along in his pocket, can he? And even if
+he managed to get the little scamp up on the thing, some trick would be
+turned that would land the 'plane on top of a high tree."
+
+"Two can ride an aeroplane, all right," Frank insisted. "Anyway, quit
+your knocking. Ned knows what he is about, and we'll wait here for him
+if we have to remain until the Rocky Mountains wash down into the
+Pacific Ocean."
+
+"Suppose we climb up on the shelf above," Jack suggested, "and see if we
+can find anything in the sky that looks like an aeroplane. I really
+think Ned and Jimmie will travel here on the air line."
+
+Pat fished a field-glass out of his haversack and passed it over to
+Jack.
+
+"You boys go on up," he said, "and see what there is to be seen. I'll
+stay here and cook this bacon. I could eat a hog on foot right this
+minute. Where did you put those canned beans?"
+
+"Never you mind the canned beans," laughed Jack. "It will be time enough
+to open them when you get the bacon fried to a crisp. I see our finish
+if you got one of the bean cans opened. Say, but I could eat a peak off
+the divide!"
+
+"Well, the divide is up there, all right," Pat grinned, "go on up and
+take a bite off it. On this side that ridge away up there the rivers run
+into the Pacific ocean. On the other side they run into the Atlantic
+ocean. Split a drop when you get on top and send your best wishes to
+both oceans. And don't you remain away too long, either, for this bacon
+is going to be cooked in record-breaking time."
+
+Leaving Pat to prepare the supper, Frank and Jack turned their faces
+upward toward the main divide of the Rocky Mountains, 4,000 feet above
+their heads. It was a splendid scene, and they enjoyed it to the full.
+To the north the green forests of British Columbia stood crinkling under
+the almost direct rays of the August sun, to the east, almost over their
+heads, stood the backbone of the continent of North America, to the
+south stretched the broken land of Montana, while to the west lay the
+valleys and ridges of Idaho, Montana, and Washington beyond which pulsed
+the mighty swells of the Pacific.
+
+Immediately to the north of the position occupied by the camp, and
+within a mile of the international boundary line, Kintla lake lay like a
+mirror in the lap of the mountains, reflecting peaks and silent groves
+in its clear waters. From the lake, ten miles in length by half that in
+width, an outlet flowed westward into the North Branch of the Flathead
+river.
+
+The level plateau where the camp had been pitched was not far from two
+acres in extent, with the bulk of the mountain to the east, a drop of a
+thousand feet to the south, and steep but negotiable inclines to the
+west and north. The lake was 300 feet below the level of the plateau,
+which was about 3,000 feet above the sea level and 4,000 feet below the
+summit of the divide at that point in the long range of mountains.
+
+There were peaks to the north and south which showed eternal snow and
+ice, but there was a lowering of the shoulder of the great chain
+directly to the east, so there was no snow in sight there. There were
+forest trees low down in the caņon to the south, and on the slopes to
+the west and north, but the plateau and the sharp rise toward the summit
+were bare.
+
+While Pat sliced his bacon and mixed corn-meal, soda, salt and water to
+make hoecakes, to be fried in bacon grease, Frank and Jack wormed their
+way up the face of the mountain, toward a shelf of rock some hundred
+feet above the plateau. It was hard climbing, but the lads persisted,
+and soon gained the elevation they sought, from which it was hoped to
+gain a fine view of the country toward Missoula.
+
+"Good thing we don't want to go any farther," Frank exclaimed, throwing
+himself down on the ledge and wiping his streaming face. "We couldn't
+scale the wall ahead with a ladder. Now," he went on, "look out there to
+the south and see if there's an aeroplane in sight."
+
+Jack brought out the field-glass and looked long and anxiously, but
+there was no sign of a man-made bird in the clear sky.
+
+"I don't believe, after all, that he'll come in an aeroplane," the boy
+said, directly. "Suppose he took a notion to get a motor boat and run up
+the north branch of the Flathead river, and so on into Kintla lake, down
+there? How long would it take him to make the trip?"
+
+"About ten thousand years," was Frank's reply. "He never could get up
+the north branch. There's too many waterfalls. Why, man, the stream
+descends several thousand feet before it gets to sea level."
+
+"Anyway," Jack replied, "if you'll get out of my way I'll take a look at
+the lake through the glass."
+
+"You'll probably see him come sailing up the slope in a battleship,"
+Frank said, in a sarcastic tone.
+
+Jack, without speaking, turned his glass to the north and gazed long and
+anxiously over the lake. Presently Frank saw him give a start of
+surprise and lean forward, as if to get a closer view of some object
+which had come into the field of the lens.
+
+"What is it?" he asked.
+
+Jack passed him the glass with no word of explanation, and the boy
+hastily swept the shores of the mountain lake.
+
+"I don't see any motor boat," he said, directly.
+
+"Well, what do you see?" Jack asked, expectantly.
+
+"For one thing," Frank replied, "the smoke of a campfire."
+
+"I saw that, too," Jack said, "and didn't know what to make of it. Also,
+I saw a rowboat sneaking around that green point to the east."
+
+"That is what is puzzling me," Frank replied. "Years ago there was a
+Blackfoot reservation just over the divide, and a Flathead Indian
+reservation down by Flathead lake, to the south, but I had no idea the
+Indians were still about. Still, the people you saw were probably
+Indians. Suppose we go down there and look the matter up. We've got to
+have some sort of a yarn to tell Pat when we get back to camp."
+
+The two boys scrambled down almost vertical surfaces, edged along narrow
+ledges, slid down easier inclines, and finally came to the rim of beach
+about the lake. There, at the eastern end of the pretty body of water,
+they came upon the still glowing embers of a fire.
+
+Close to the spot where the remains of the fire glimmered in the hot
+air, they saw the mouth of a cavern which seemed to tunnel under the
+body of the mountain to the east. There were numerous tracks about the
+fire, and some of them led to the entrance to the cavern.
+
+"Whoever built this fire," Jack exclaimed, "wore big shoes, so it wasn't
+Indians. No, wait!" he added, in a moment, "there are tracks here which
+show no heel marks. What do you make of that?"
+
+"Must be moccasins," Frank said. "The Indians may still be in the woods
+about here."
+
+"I'm going into the cavern to see what's stirring there," Jack said,
+"and before I go I'll have a look at my artillery."
+
+The boy looked his revolver over, and before Frank could utter a
+warning, he darted away into the gloom of the cave. Frank did not follow
+him, but turned in the direction of the point where the boat had
+disappeared.
+
+A dozen yards on his way he stopped and listened. A voice, sounding like
+that of a person in a deep well, reached his ears, and he turned back.
+
+He gained the mouth of the cavern in half a minute and plunged inside.
+It was dark a dozen feet from the entrance, but he struck a match and
+moved on, finally coming to a smooth wall which appeared to shut off
+farther progress.
+
+When he turned about and faced the opening every object between where he
+stood and the mouth stood revealed against the bright sunshine outside.
+There were a few loose rocks, a rude bench, a small goods box, and
+nothing else. Jack was nowhere in eight.
+
+He examined the walls of the cavern but discovered no lateral passages.
+He called out to his chum, but received no response. Where was Jack? If
+he had left the cavern he would have been seen. It was a perplexing
+mystery, and the boy sat down on the box and listened for a repetition
+of the sounds he had heard.
+
+For a moment no sounds came, then a voice, seemingly coming out of the
+solid wall behind him reached his ears. He could distinguish no words
+for a time, and then it seemed that he was being called by name.
+
+He called to Jack again and again, but received no answer. Jack was
+evidently there somewhere, but where? The smooth walls gave no
+indication of any hidden openings, and there was in view no crevice
+through which a voice behind the walls might penetrate. It seemed either
+a silly joke or an impenetrable mystery.

+
+CHAPTER II.--THE SIGNAL IN THE SKY.
+
+
+Frank left the cavern in a moment and walked along the beach toward the
+campfire. His thought was to gather embers and fresh fuel and build up a
+blaze at the end of the cave which would reveal every inch of the
+interior. He was certain that Jack had not left the place, and decided
+that he had fallen into some hidden opening which had escaped his own
+investigation.
+
+As he bent over the remains of the fire he heard a rattle of small
+stones, and, looking up, saw Pat coming down the declivity from the
+plateau where the tents had been set up. The incline was steep, and at
+times Pat was rolling rather than walking. He was in his shirt sleeves
+and bareheaded. At last his red head pitched toward the lake like a
+meteor in downward flight.
+
+Frank rushed forward and caught him as he struck the beach, thus saving
+him from an impromptu bath. Pat struggled to his feet in an instant,
+rubbed his legs and arms to see if any bones had been broken, and then
+turned his head and looked up the incline.
+
+"Talk about shooting the chutes!" he exclaimed. "I wonder what time I
+made coming down?"
+
+"Sure you're not hurt?" asked Frank anxiously.
+
+"Every inch of my body has three bruises, one on top of the other," Pat
+replied, "but I guess I'm able to walk. Say, but that was a
+roller-coaster glide!"
+
+"Why did you try such a foolish caper?" asked Frank.
+
+"Why, I saw you boys here," was the reply, "and started down. You know
+the rest, as the yellow-covered books say. What you boys doing here,
+wasting your time, with the bacon burning to a crisp?"
+
+"We came here to investigate," was the reply, "and Jack went into the
+cavern, and vanished--just vapored into thin air. I'm going to build a
+fire in there and see if I can't condense him!"
+
+"Well," Pat said, listening, "he may have vanished physically, but his
+voice appears to be on deck yet."
+
+Three sharp calls came from the cavern, and both boys dashed inside.
+There was no doubt now that Jack's voice, at least, had condensed, for
+the shouts coming from the back of the cavern were both hearty and
+imperative.
+
+"Hi, there!" Jack called. "Pry this stone out of the doorway!"
+
+"Where are you?" demanded Pat. "Which one of the walls do you want us to
+push in? You're a nice chump, getting in a scrape like this!" he added,
+with a laugh which must have been exasperating to the unseen boy.
+
+"You'll find a crevice where the back of the cave joins the south wall,"
+Jack said, his voice coming faintly to the ears of his chums. "Put your
+fingers in and pull. The blooming door opens outward. Hurry! It's
+stifling in here!"
+
+After burning nearly all the matches they had in their pockets, and
+scorching their fingers on the short sticks, Pat and Frank discovered
+the crevice spoken of and inserted the ends of their fingers.
+
+"Pull!" yelled Jack. "Pull, you loafers! It is moving!"
+
+In a moment the south half of the back wall swung out so suddenly that
+both boys were thrown from their feet and Jack, who had been pushing
+with his whole strength, came tumbling on top of them as they lay on the
+floor of the cavern.
+
+"What sort of a combination is this, anyway?" demanded Pat, struggling
+to his feet. "If I get any more bumps to-day I'll be taking something
+that belongs to some one else. I've had my share."
+
+Frank sprang to the opening as soon as he could disentangle himself from
+the collection of arms and legs and looked in. All was dark and still
+inside, and a gust of dead air struck him in the face. Pat, leaning over
+his shoulder, laid a hand on the rock which had opened so strangely, and
+the next instant it closed softly, sliding into the opening like a door
+operated by well-oiled machinery.
+
+"Now you've done it!" Frank exclaimed, disgustedly, as Pat threw himself
+against the stone in a vain effort to force it open again.
+
+"No harm done," Jack exclaimed. "There's only a stinking cavern in
+there. Wow! I can feel snakes and lizzards crawling on me now! Come! Let
+us get into the open air. Stifles like a grave in here."
+
+The boys hastened outside and stood meditatively before the shining
+waters of the lake, each one trying to think clearly concerning what had
+taken place. They believed themselves--or had believed, rather--miles
+away from any trace of civilization, and yet here was a practical door
+of rock at the end of a cave almost under the great divide.
+
+"We've found something," Frank said, at length. "That thing in there
+never happened. Human hands fashioned that door for some secret purpose.
+And it wasn't Indians, either."
+
+"I guess we've run up against a band of train robbers," suggested Jack,
+with a grin.
+
+"Probably the entrance to some deserted mine," Pat put in. "This region
+has been searched for gold for fifty years. I've heard of mines being
+concealed by moving stones."
+
+"Well," Frank said, after a short silence, during which all listened for
+some indication of the immediate presence of the men who had been seen
+to row around the green point a short time before, "whatever the game
+is, we've got to remove every trace of our visit. When they come back
+they probably won't notice the tracks we have made, for there were
+plenty about before we came here, but we must gather up all the
+match-ends we left in there and leave the door as we found it."
+
+"I found it open and walked in," Jack said, "and then it closed. Whew! I
+felt like I was being shut up in a tomb!"
+
+"How large a place is it in there?" asked Pat.
+
+"Don't know," was the reply. "I had no matches with me, and so could not
+see a thing."
+
+"Then we won't have to open the door again to clean up any muss," Frank
+said, moving toward the entrance to the cavern.
+
+"I wouldn't go in again for a thousand dollars," Jack cried. "If you
+leave it to me, the place is haunted. I heard groans in there."
+
+Frank paused at the entrance and turned back. His matches were about
+gone, and so he took a burning stick from the fire, added two dry
+faggots to it, waited until the three burst into flame, and then entered
+the cave.
+
+To gather up the half-burned matches which had been scattered over the
+floor was the work of only a moment.
+
+"Now you'll have to open the door, if you leave it as I found it," Jack
+said, looking in from the mouth. "Pat will help you."
+
+"Come on in, both of you," Frank directed.
+
+"Not me!" cried Jack. "I hear bones rattling!"
+
+The boys thought he was joking at first, but it soon appeared that he
+was in sober earnest, so Pat and Frank, by exerting their entire
+strength, managed to open the door without his assistance.
+
+"You're afraid of the dark!" Pat taunted, as the boys gathered around
+the fire again.
+
+"I'm not half as afraid of the dark as you are of an aeroplane," Jack
+replied. "If I ever see you going up in a 'plane, I'll go in there
+alone."
+
+"Don't you ever forget that," Pat grinned.
+
+"Oh, I'll be game, all right," was the reply.
+
+Before leaving the beach for the camp the boys walked to the point
+around which the boat had gone and scanned the lake and its shores
+through the field-glass. There was no sign of life anywhere, except
+where the birds swung from forest limbs back from the rim of the lake
+and called each other through the sultry air.
+
+Reaching the camp after a weary climb, they did full justice to the meal
+which Pat had prepared, though the bacon and the hoecakes were stone
+cold, or at least as cold as anything could be in that glare of
+sunlight. Then, the dishes washed and the beds prepared for the night,
+they sat down to watch the lake and the sky to the south, for it was now
+the general belief that Ned would make his appearance with the aeroplane
+which had been promised by the government officials.
+
+The point they had last visited, as well as the location of the fire,
+was in full view of the plateau, so the boys made no efforts to conceal
+their presence there. The men who had been observed in the boat must
+have noted their presence on the plateau before taking their leave.
+Perhaps, they reasoned, they had taken their departure because of this
+invasion.
+
+The sun sank lower and lower in the sky, turning the plateau and the
+smooth waters of the lake to gold, still there were no signs of Ned, no
+indications of the return of the boat to the place from which it had
+been launched. Half an hour after dark, Frank, who was looking through
+the field-glass, caught sight of light in the south which did not appear
+to come from any star.
+
+"Here he comes!" he cried. "That's an aeroplane, all right!"
+
+As the light drew nearer, traveling rapidly, the sharp explosions of the
+gasoline engine became audible. Then a light flickered over the upper
+plane, passed off, and swept the white surface again.
+
+"How does he make that?" demanded Pat. "Looks like a great question
+mark."
+
+"That's what it is," Frank exclaimed. "Now, what does he mean by it?"
+
+
+
+
+Chapter III.--JUST A TYPEWRITER RIBBON.
+
+
+"I don't understand what question he is asking," Jack said, "but I know
+how he makes the signal. He has an electric flashlight, and he tips the
+plane--the upper plane--forward, like he was plunging to the earth, and
+writes the interrogation mark on the under side with the flame of the
+flashlight. See? Then it shines through the canvas and we read it! Great
+idea!"
+
+"That must be the way of it," Frank said, "but what does he want? And
+how does he expect us to answer?"
+
+"If I was up there in the dark on a contraption like that," Pat said,
+"I'd be asking how I was going to find a landing place."
+
+"Sure!" Frank cried. "Ned wants to know where we are, and whether it is
+safe for him to make a landing. Dunderheads! Why didn't we think of that
+before? He is passing now, and may not come back again."
+
+The light flashed by at swift speed, whirled, ascended several hundred
+feet, and came over the plateau, repeating the signal. Then it settled
+down into a steady circling of the camp.
+
+"He knows where we are, all right," Pat said. "What he wants to know is
+if it is safe for him to make a landing. If I ever go up in one of those
+things I'll drag a rope so I can climb down it."
+
+"I'll tell him what he wants to know," Frank said, "if you'll get me a
+long stick on fire most of its length."
+
+"Wigwag?" asked Jack.
+
+"Sure!" was the reply. "Now," Frank continued, "build four fires, one on
+each edge of the plateau. That will show him how large the place is.
+Then I'll take the flaming stick and wigwag o.k. Ned'll understand
+that."
+
+Pat watched the wigwag signal with interest.
+
+"I saw foolish signs like those in the Philippines," he said, with a
+grin. "The natives use them to talk treason to each other. I've heard
+that the same method is used by the East Indians who talk from one
+mountain top to another faster than words on a wire. How does he make
+the o.k. signal?"
+
+"O is one left, followed by one right," Jack replied, "and k is left,
+right, left, right. You won't think the signs are foolish when you see
+how quickly Ned reads them. See! He's shooting away now."
+
+"Perhaps he thinks the signals are being made by savages," Pat said.
+
+The aeroplane darted off to the west for half a minute, then whirled and
+came back. The boys could not see the great 'plane distinctly, but the
+lights which burned on the front were bright and clear, so they saw that
+the 'plane was sweeping toward the earth as it advanced in their
+direction.
+
+"I don't believe many professionals would care to make a landing like
+this," Frank said, as the machine dipped and slid to the ground, exactly
+in the center of the plateau.
+
+"Hello, Ned!" he yelled, as the aeroplane rolled over the smooth surface
+for an instant and stopped.
+
+In a second the three boys were gathered about the machine, pulling at
+the hands and feet of the daring riders. Jimmie McGraw bounded to the
+ground as soon as he could cast off the lines which had held him to his
+quivering seat.
+
+"Say," he cried, "you got a fire here? I'm most froze."
+
+Indeed the little fellow's teeth were chattering.
+
+"Cold?" echoed Pat. "We're melting down here. You're scared, that's
+what's the matter with you. You're scared stiff."
+
+Jimmie made a run for the speaker but brought up at the fire where the
+supper had been cooked.
+
+"Here's comfort!" he cried, extending his hands out over what was left
+of the small blaze. "The next time you get me up in the air I don't go!
+I've been freezing for an hour."
+
+In the meantime Ned Nestor was caring for the aeroplane, looking after
+the delicate machinery and covering it carefully with a huge oil-cloth.
+Pat stood watching the work with a grin on his face.
+
+"Are you thinking of giving me a ride in that thing?" he asked.
+
+"Not to-night!" laughed Ned.
+
+"Well, when you get ready for me to ride the air," Pat said, "just tell
+me the night before, and I'll shoo myself into the hills. If I'm going
+to fall off anything, I'll take the drop from something solid, like a
+mountain top."
+
+"No danger at all, when you know how to operate the machine," Ned
+replied. "There's danger in running anything if you don't know how, even
+a sewing machine."
+
+"Where did you pick it up?" asked Frank.
+
+"He didn't pick it up at all," interposed Pat. "It picked him up."
+
+"I found it at Missoula," was the reply, "all packed and stored away in
+a freight warehouse. I had to get it out at night, and so lost time. The
+people would have kept me there until now giving exhibitions if I had
+shown up during the day."
+
+"But you did leave there in the daytime," urged Jack. "You were never in
+the air since last night."
+
+"We left early this morning," was the reply, "and I was well up in the
+sky before many of the people saw me."
+
+"I never knew you could run one," Frank said.
+
+"Oh, I had some instructions from the Wrights," was the modest reply,
+"and, besides, there was an expert at Missoula who helped me get the
+machine together and contributed a few parting instructions."
+
+"Then you've been in the air all day?" asked Pat.
+
+"No, we stopped several times, of course, once on the right of way of
+the Great Northern railroad and filled our gasoline tanks," was the
+reply, "and rested there a few hours. Jimmie had to eat there, of
+course!"
+
+"Eat!" came the boy's voice from the fire. "If I ever get a bite at food
+again it will drop down into the toes of me shoes! Here!" he shouted, as
+Pat produced a can of pork and beans and started to open it. "You
+needn't mind opening that! I'll just swallow it as it is."
+
+"Bright boy!" laughed Pat, handing him a liberal supply of beans and
+fried bacon. "Now fill up on that and then loosen up on your impressions
+of the sky."
+
+"I thought I'd make an impression on the earth before I got through,"
+Jimmie mumbled, his mouth full of beans. "We went up so far that the
+mountains looked like ant hills, didn't we, Ned?"
+
+"About 7,000 feet," was the reply. "You see," he added, turning to
+Frank, "I wanted to size up the situation before I landed. If there is
+anybody in this upturned country at all, our presence here is known. The
+aeroplane's chatter took good care of that. And, besides, our landing in
+the night, with the lights going, gave unmistakable evidence of
+something stirring."
+
+"I should say so," Frank agreed.
+
+"And so," Ned went on, "I wanted to learn if there were people about
+here, so I might visit them in the morning and put up the bluff of Boy
+Scouts playing with an aeroplane in the woods. We can't attempt anything
+in the mysterious line," he went on. "We've got to be entirely frank
+about everything except the business we are here on."
+
+"Well," Frank said, "we found people here to-day and called on them."
+
+"What sort of people?"
+
+"Well, they seemed to have good broad backs," laughed Frank.
+
+"They ran away from you?" asked Ned, in surprise. "I should think they
+would have proved inquisitive. Where were they?"
+
+"Down by Kintla lake."
+
+"Indians?" asked Ned.
+
+Then Frank told the story of the visit to the shore of the lake and the
+cavern, taking good care to describe the surroundings as closely as
+possible. Ned laughed when the boy came to Jack's adventure in the
+hidden chamber.
+
+"I say it is some deserted mine," Pat declared, when Frank had concluded
+the recital. "What else could it be?"
+
+"Robber's nest!" suggested Jack.
+
+Ned remained silent for a moment and then abruptly asked:
+
+"What kind of footwear made those heelless prints?"
+
+"You may search me!" Jack cut in.
+
+"Must have been Indian moccasins," Frank observed.
+
+Jimmie, who had been standing by the small fire, listening to the talk,
+now advanced to the little circle about the machine and uttered one
+word: "Chinks!"
+
+"It is always Chinks with Jimmie," grinned Frank. "When there is a
+cyclone in New York the Chinks are to blame for it, if you leave it to
+him."
+
+"What would Chinks be doing up here?" demanded Pat.
+
+"Don't they get gold by washing it out?" asked Jack, with a nudge at
+Jimmie's side. "Perhaps they're going to start a laundry!"
+
+While this chaff was in progress Ned stood looking thoughtfully in the
+direction of the lake. Not a word did he say regarding the sudden and
+brief communication Jimmie had presented.
+
+"Any forest fires in sight?" asked Pat, finally breaking the silence.
+
+"Not one," Jimmie answered. "I would have dropped into one if it had
+come my way. It was fierce up there!"
+
+"It is rather cool when you get up a couple of miles," Ned laughed, "and
+Jimmie wouldn't listen to reason regarding his clothes. To-morrow I'll
+give one of you boys a ride, and you may see for yourself."
+
+"Not me!" Pat exclaimed. "I'll stay below and help pick up the pieces."
+
+"I should like to go," Frank said. "We may find the people we saw in the
+rowboat. When we become acquainted with them we may be able to learn
+something about that cavern."
+
+"I would advise remaining silent about the cavern," Ned said. "It may be
+used for some criminal purpose, and we must not admit that we know of
+its existence. We are just carefree lads, here for an outing, remember,"
+he added, with a laugh, "and we are due to make friends with everybody
+we come across."
+
+"But you made us lug all this camping outfit up here," complained Jack,
+"so the men who steered the burros up the hills wouldn't know where we
+camped. What about that?"
+
+"I thought it best to cut off all communication with the people below,"
+explained Ned. "It may be that the purpose of our visit here is
+suspected. In that case some one from below might want to find us--for
+no good purpose. So we'll keep out of sight of the people in the towns,
+unless they see our aeroplane, and cultivate the acquaintance of the
+natives--if there are any."
+
+"How about gasoline and provisions?" asked Pat.
+
+"I have plenty of gasoline stored on the right of way of the Great
+Northern railroad," Ned replied, "enough to last us a month. It was
+piped into a hidden tank from an oil car by a train crew now out of the
+state. We are to get provisions at the same place, if we need more, for
+Uncle Sam fixed all the details for us. All we have to do is to find the
+fellows who are setting forest fires and bring them to punishment."
+
+"We ought to locate every little smudge, with that aeroplane," Frank
+suggested.
+
+"That is my idea," Ned replied. "Have you been keeping a good lookout on
+the lake since you left it?" he added, turning to Pat.
+
+"Some one of us has had eyes on it every minute," was the satisfactory
+reply. "No one has returned, I'm sure."
+
+"You're not thinking of going there to-night, are you?" asked Jack, with
+a slight shiver. "I wouldn't go in there again, even in broad daylight,
+for a million dollars!"
+
+"Pat is afraid of the sky, and Jack is afraid of the bowels of the
+earth!" laughed Frank. "We'll have to tuck them both in bed before we
+can accomplish anything."
+
+"You may all go to bed but one," Ned said, looking about the group, his
+eyes finally resting with a significant look on Frank's excited face. "I
+want to look through that cavern before anything is taken out of it."
+
+Frank, knowing the meaning of the look he had received, went to his
+little tent for his revolver and his electric searchlight and was soon
+ready for the expedition. Jimmie looked sulky for a moment at being left
+out of the game, then his face brightened and he crawled into the tent
+that had been prepared for Nestor and himself and burst into a fit of
+laughter.
+
+"I'll show 'em!" he said, stuffing the blanket into his mouth to
+suppress the sound of his merriment. "I'll teach 'em to put me in the
+discard."
+
+"Any wild animals up here?" asked Ned, as the two started away down the
+steep declivity.
+
+"Two Black Bears and three Wolves!" called Jimmie, from his tent.
+
+This was a reference to the Boy Scout Patrols to which the boys
+belonged. Frank and Jack were members of the famous Black Bear Patrol of
+New York City, while Ned, Pat and Jimmie were members of the Wolf
+Patrol.
+
+As the lad spoke Frank and Jack broke into growls which might well have
+come from the throat of the grizzliest grizzly in the Rocky Mountains,
+while Pat sent forth a wolf howl, which might well have been a signal to
+the pack.
+
+"You may meet the real thing out here," warned Ned, turning back to look
+over the plateau, now shining in the light of a half-moon. "There are
+both bears and wolves in this region. When you meet them, don't wait for
+Boy Scout signs!"
+
+"Oh, we'll initiate 'em, all right," Jimmie called from the tent, and
+Ned and Frank moved on down the declivity toward the lake.
+
+It was still early evening, and the moon was low down in the east, so
+the valley where the lake lay was not touched by its light. Indeed, the
+plateau where the boys were would have been in the shadow of the
+mountain only for the dropping of the shoulder of the divide.
+
+In half an hour the two boys, after several slides which were anything
+but pleasant, gained the beach. The campfire was now dead, and the
+locality was still save for the voice of a night bird and the occasional
+splash of a leaping fish. The mouth of the cavern loomed like a dark
+patch on the lower bulk of the mountain.
+
+Making as little noise as possible, Ned and Frank crept into the cavern,
+advancing by the sense of feeling until they came to the very end before
+turning on one of the electric flashlights. The round eye of the flame
+showed a long, narrow, tunnel-like tube running directly east, under the
+mountain. The door of rock was as the boys had left it earlier in the
+day.
+
+Ned examined that portion of the rock which had swung out into the first
+chamber with considerable care, as the story of the swinging stone had
+interested him greatly. All along the top, up to the center, he found
+the checks of a stone-chisel. Exactly in the middle an elevation of an
+inch fitted into a round cavity in the upper rock. At the bottom the
+same conditions were discovered.
+
+"Rather a clever job," Ned said, "but I don't see how it was ever done."
+
+"This door," Frank said, "is not exactly like the remainder of the wall
+in grain, so it must have been brought here from some other locality. Of
+course there was a hole between these two chambers, or the second one
+would never have been found. It would be easy enough to fit the stone
+door in by grooving out from the lower cavity and sliding the under
+pivot in."
+
+"Sure," Ned replied, getting down to examine the lower part of the door
+more closely, "and that is just what was done. Then the groove was
+filled with concrete. Pretty classy work here!"
+
+"And now the question is this," Frank went on, "what was the door fitted
+for? Why did the men who found the cave desire privacy? Is there gold in
+there? Have the men who have been setting fire to the forests
+established a home here? Is this the hiding place of a band of outlaws?
+You see there are lots of questions to ask about the two caverns," Frank
+added, with an uneasy laugh.
+
+Ned closed the stone door and turned on both electric flashlights,
+making the place light as day where they stood. The inner cavern was as
+bare as the outer one save for dead leaves and grass which lay in heaps
+on the stone floor, and for half a dozen rough benches which were piled
+in one corner. At the farther end hung a gaudy curtain, once handsome,
+but now sadly spotted with mildew because of dampness.
+
+"Here's the inner chamber," laughed Frank, drawing the curtain aside.
+"And it looks like it was the private office of the bunch, too," he
+added, as he turned the light about the walls.
+
+There was a desk in the third cavern, a swivel chair, a small case of
+books, and a rusty safe, which looked as though it had not been opened
+for years. A current of fresh air came from the rear, and a small
+opening was soon discovered.
+
+"That doubtless leads to some caņon not far away," Ned said. "Makes a
+pretty decent place of it, eh?"
+
+"Good enough for any person to hide in," replied Frank. "Now," he added,
+"tell me what you think of it. Who cut this cavern, and who brought the
+furniture here? I'll admit that my thinker is not working."
+
+"Nature made the caverns," Ned replied. "There is what geologists call a
+fault in the rock here. Owing to volcanic action, doubtless, the strata
+shifted, probably thousands of years ago, and when the seam appeared the
+broken pieces fell apart. These chambers show the width of the seam.
+There undoubtedly was a great earthquake at the time, and the lake below
+might have been dredged out at that time."
+
+"Of course," Frank said, "I might have known that! Now, here's another
+question: How far does this seam extend under the Rocky Mountains? If it
+passes beyond these three chambers, why not make a fourth room for
+ourselves so as to be on the spot when the men who make headquarters of
+the place come back?"
+
+"That may be a good thing to do," Ned admitted, "but, still, I would not
+like to be the one to lie in wait here. Suppose we try to learn
+something of the character of the people who come here? They seem to
+sleep on dry leaves and eat off benches. Rather tough bunch, I take it.
+Perhaps we have struck Uncle Sam's enemies the first thing!"
+
+Keeping their lights on, and working as silently as possible, always
+with an eye to the outer cavern, the boys made a careful search of the
+inner chamber. The desk was not fastened, and a cupboard afterward
+discovered in a niche was open also. There were dishes in the cupboard
+and writing materials in the desk.
+
+At the very bottom of the desk drawer Ned came upon a surprise.
+
+"Not so tough as I supposed," he said, turning to Frank. "Here's a
+typewriter ribbon. The sort of people who set fire to forests and hold
+up trains are hardly in the typewriter class. What do you make of it?"
+
+"Well," Frank said, with a chuckle, "if you'll tell me what the
+inhabitants of this place want of typewriter ribbons I'll tell you why
+they bring great tins of opium here. It seems that we have struck
+something more important than forest fires."
+
+
+
+
+CHAPTER IV.--THE AEROPLANE IN DANGER.
+
+
+A strong wind came out of the Western Sea at ten o'clock that night and
+swept the lofty plateau as a woman might have swept it with a new broom.
+Ned and Frank, pursuing their investigations in the cavern, knew nothing
+of what was going on at the camp, but Jack and Pat were not long in
+ignorance of the danger of the situation.
+
+With the first strong rush of wind the boys were on their feet,
+steadying the aeroplane, driving stakes wherever the nature of the
+ground permitted, and running bracing cords. The shelter tents went down
+instantly and were blown against the rocks of the east, where they waved
+canvas arms in the tearing breeze like sheeted ghosts.
+
+The black clouds which swarmed up from the valley brought no rain, but
+fitful flashes of lightning and deep-toned thunder made a threatening
+sky. The roaring of the swirling trees in the caņon and on the slopes
+came up to the ears of the boys like the boom of a strong surf.
+
+After persistent efforts the boys succeeded in bracing the aeroplane so
+that there was little danger of its being swept away, though they still
+remained with their backs to the wind, holding on. As time passed, they
+crept close together in order that the situation might be discussed.
+
+"Lucky thing we remained here," Pat said, tugging with all his might to
+steady the monster machine against a particularly vicious dash of wind.
+
+"It would have gone sure, if we hadn't," Jack screamed back. "I wish Ned
+and Frank would come and help. My back is creaking like a shaft that
+needs oiling with the strain on it."
+
+"A little help wouldn't go amiss," Pat admitted, shouting at the top of
+his lungs in order that he might be heard above the whistling of the
+storm.
+
+"I wonder if we'll ever be able to put the tents up again?" Jack
+shouted. "They are flapping and snapping like musketry out there on the
+rocks. I hope they won't blow away entirely."
+
+Pat gazed anxiously in the direction indicated, but could only see
+pieces of canvas bellying up in the wind, mounting upward like balloons
+at times, then falling back to earth when a short lull came in the
+storm.
+
+"Why," he cried, in a moment, "where's Jimmie? I thought I saw him here
+a moment ago. Have you seen him?"
+
+"Not since the storm," panted Jack.
+
+"He may have been smothered in his tent," Pat shouted. "You hold on here
+while I go and look him up."
+
+"Be sure that you keep close to the ground," warned Jack. "If you don't
+you'll be blown away."
+
+It was not at all difficult for the lad to reach the flapping tents, for
+the wind generously assisted him in the journey. Only that he crept on
+his hands and knees he would have been tossed against the wall where the
+tents lay.
+
+Struggling with the tearing canvas, bracing himself against the face of
+the cliff, the boy looked over the ruined tents but found no indication
+of the presence of the boy he sought, either dead or alive. Then he felt
+along the angle of the foot of the rise with no better success.
+
+"He's not there," he reported, crawling back to Jack, now braced
+tenaciously with his toes and elbows digging into the soil above the
+rock.
+
+"Did you find his clothes?" asked Jack.
+
+"Not a thing belonging to his outfit," was the reply.
+
+"Well, he went to bed, didn't he?" asked Jack, a sudden suspicion
+entering his mind.
+
+"He went into his tent," was the reply, "but I did not see him undress."
+
+Then Pat, much to his astonishment, heard Jack laughing as if mightily
+pleased over something that had taken place.
+
+"You've got your nerve!" he exclaimed. "Laughing at a time like this.
+I'll bet the kid has been blown off the plateau."
+
+There was now a little lull in the drive of the wind and Jack nudged his
+companion with his elbow, turning an amused face as he did so.
+
+"Blown off nothing!" he said. "You saw how he acted when Ned went off
+without him--how sulky he was?"
+
+"I noticed something of the sort."
+
+"Well, Jimmie ducked after him!"
+
+"Why, he was told to remain here."
+
+"He has been told that before," Jack said, "and he's never obeyed
+orders. He followed Ned from Manila to Yokohama, not long ago, and made
+a hit in doing it, too. Oh, it is a sure thing that Jimmie is not far
+from Ned at this minute."
+
+"The little scamp!" grinned Pat.
+
+"He seems to think that Ned can't get along without his constant
+presence and his pranks," Jack continued. "He generally stirs something
+up in his immediate vicinity, but he's a pretty good scout at that."
+
+"I hope he is with Ned," Pat said.
+
+The wind now died down a bit, so that it was no longer necessary to hold
+the aeroplane, and the boys, after seeing that the rope still held,
+began the work of repairing the tents.
+
+The clouds drifted away and the moon looked down as bravely as if it had
+not just hidden its face from sight at the threats of the wind! The
+electric flashlights with which the boys were well provided seemed
+inadequate and Pat started in to build a fire.
+
+"I don't know about that," Jack said. "If there had been a fire here
+when that wind came up it would have been roaring in the caņon now. The
+storm would have swept it down on the trees there, and the whole gully
+would soon have become a roaring furnace. Better cut out the fire."
+
+"I guess you are right," Pat said, reluctantly laying his dry faggots
+aside.
+
+While the boys worked, trying to restore the shelter tents to something
+like form, the wind came up once more and reached out for the aeroplane.
+Pat and Jack renewed their holding efforts, and thanked their stars that
+no fire had been built on the plateau, for the forest about was dry as
+tinder.
+
+Presently a voice which neither recognized came out of the shadows cast
+by a mass of clouds just then occupying the sky where the moon should
+have been.
+
+"Hello!" the voice said.
+
+The boys looked at each other in perplexity for a moment and then Jack
+answered back.
+
+"Hello!" he said.
+
+"Are you all safe up here, safe and sound?" the voice asked, and then
+the figure of a tall man, roughly dressed, but bearing the manner, as
+faintly observed in the darkness, of a gentleman, advanced toward the
+aeroplane, to which the lads were still devoting their whole attention.
+
+"Safe and sound!" repeated Pat.
+
+The stranger sat down by Jack's side and laid hold of the aeroplane.
+
+"Pulls hard, doesn't it?" he asked, as the machine, forced by the wind,
+drew stoutly on the ropes and the muscles of the boys.
+
+[Illustration: ILLUSTRATION No. 2]
+
+"Pulls like a horse," Jack replied.
+
+"I'm Greer, of the forest service," the stranger said, in a moment. "I
+saw a fire up here this afternoon, and I was afraid harm might come from
+it during the gale. One blazing brand down in that caņon, and millions
+of feet of timber would be destroyed."
+
+"As you see," Jack said, "we have no fire."
+
+"This, I presume," Greer said, still pulling at the machine, "is the
+aeroplane your friends came in this evening?"
+
+"The same," replied Pat shortly.
+
+The lad was annoyed to think that the forester, as he called himself,
+had been watching them. If he had taken so much interest in their
+movements, Pat thought, why hadn't he shown himself before?
+
+Jack's thoughts seemed to be running in the same direction. In fact,
+both boys were suspicious of this soft-spoken stranger who had come to
+them out of the storm with questions on his lips.
+
+"Where are your friends?" Greer asked, in a moment. "I hope they are not
+out in the forest thinking of starting a fire?"
+
+"They've gone to the lake after fish," Jack said, accounting for the
+absence of the others with the first words that came to his lips.
+
+Greer gave a quick start and leaned over to look into Jack's face.
+
+"Down at the lake?" he repeated. "Not out in a boat in a storm like
+this?"
+
+"No," replied Jack, gruffly, so gruffly, in fact, that the stranger
+caught the hostile note and turned away.
+
+"I'm always afraid of fire on a night like this," Greer continued in a
+moment, "and rarely sleep until morning. My cabin is back on the
+mountain a short distance, some distance above this plateau. That's how
+I happened to see what was going on here."
+
+"Rather a lonely life," Pat said, resolved to keep the fellow talking if
+he could. "Because," he reasoned, "you can tell what's in a man's head
+if he keeps his mouth open and his tongue moving, but no one can tell
+the secret locked up behind closed lips."
+
+"Yes, it is rather lonely," Greer replied. "I'm glad you boys are here.
+Going to remain long?"
+
+"Only a few weeks--just to hunt and fish," was Jack's reply.
+
+"If you don't mind," Greer went on, "I'll come down and visit you now
+and then."
+
+The statement almost took the form of a question, and Jack gave a
+grudging answer that the visits would be a pleasure, though he believed
+that the man was arranging a way of watching their movements.
+
+"I wish this wind would go down," Greer said, presently. "As I said
+before, I'm always afraid of fire on nights like this. See! The wind
+blows straight off the distant ocean strong and steady, and a fire
+started out there to the west would run over this plateau and over the
+mountain like a wash of tide."
+
+"There's nothing to burn on the plateau," Jack said, glad of an
+opportunity to contradict the stranger.
+
+"Nothing to burn!" Greer repeated. "I reckon you don't know much about
+forest fires, young man! Why, it would burn the soil down to bed rock,
+even evaporate the water in the rock itself and crumble it down to
+ashes. A forest fire is no joking matter."
+
+The boys remained silent, looking cautiously into each other's faces and
+both wondering how a forester, a man marooned in a great wilderness
+should be so exact in his speech, should wear such a shirt--actually a
+dress shirt--as they saw under his rough coat when the wind blew it
+aside.
+
+"I rather think there's more company coming," Greer continued, seeing
+that the boys were not inclined to comment on his warnings. "A moment
+ago I saw a flash of light at the foot of the rise to the west."
+
+The wind was still blowing fiercely, but both boys turned and looked
+down the incline. There was a faint light there now, glimmering among
+the trees.
+
+"It looks like a lantern," Greer said. "And the fellow seems about to
+climb the hill. Good luck to him, in this gale."
+
+"It seems to me," Pat said, "that the light we see is running along on
+the ground. If that should be a forest fire, there would be the dickens
+to pay to-night--and nothing to pay with!"
+
+"That is not the way forest fires start," Greer said, turning indolently
+in the direction of the divide. "That is a man with a lantern."
+
+The boys watched the glimmer below with interest. The man with the
+lantern, if there was a man and a lantern, seemed to be moving with the
+wind. Then, again, he seemed to divide himself, as the lower orders of
+life at the bottom of the seas divide themselves, appearing on both
+sides of a dark space at the same moment.
+
+They were satisfied that something unusual was going on, but were for
+the moment lulled into a half-sense of security by the positive
+assertions of the alleged forester. Presently they turned away from the
+scene below and fixed their eyes on the stranger.
+
+He was standing straight up, his tall figure braced against the wind,
+peering down into the caņon. Notwithstanding the steady wind, the sky
+was now comparatively free of clouds, and they saw him lift a hand with
+something bright shining in it.
+
+It appeared to the lads that he was signaling to some one in the caņon.
+They turned away instantly so that Greer did not note their observation
+of him, and again fixed their gaze on the slope to the west.
+
+The lantern, if there was a lantern, was growing larger! It was showing
+itself in half a dozen places now, and was tracing lights far up in the
+crotches of dead trees. Then the penetrating odor of burning wood and
+grass came up the slope.
+
+Filled with a fear which could hardly be expressed in words, the boys
+faced Greer again. He still stood facing the caņon to the south, but his
+hands were not lifted now. There was no need for that, the boys thought,
+for the previous signal seemed to have sufficed.
+
+Among the dry faggots on the ground at the bottom of the caņon there was
+another man with a lantern. He, too, if there was such a man, was moving
+about among the trees and dividing himself into sections, as the
+rudimental creatures of the world multiply themselves. Pat sprang to
+Greer's side and shook him roughly by the arm.
+
+"There's a fire down there!" he cried.
+
+In the uncertain moonlight the boy saw the stranger's face harden.
+
+"You are mistaken," he said, turning away toward the lake.
+
+"Smell the smoke!" Jack shouted. "I tell you the forest is on fire on
+two sides of us."
+
+"Then your friends have set the fires!" Greer shouted, against the wind.
+"I have been suspicious of you all along--ever since you failed to
+satisfactorily account for the absence of your friends. It is all very
+well for you to come here in an aeroplane and start a conflagration! But
+how do you think that we, who are not so well provided with means of
+getting away, are to escape death?"
+
+Pat drew back his hand, as if to strike the fellow, but Jack restrained
+him.
+
+"You set the fires!" Pat shouted, then. "You set it through your fellow
+conspirators! I saw you signaling to the caņon!"
+
+"You're no more a forester than I am!" Jack added. "You're a scoundrel,
+and ought to be sent to prison for life."
+
+There was no more talk for a time. Greer stood defiantly against the
+wall of rock to the east, as if fearful of an attack from behind, his
+right hand in his bulging pocket. The boys knew that he had a weapon
+there, and their own hands were not empty.
+
+The aeroplane drew and shivered in the rising gale, but now little
+attention was paid to it. Pat and Jack were listening for some
+indication of the return of Ned and Frank. No farther fable of a man
+with a lantern was necessary, for fire was racing up the western slope,
+heading directly for the plateau and the priceless aeroplane. Down in
+the caņon the flames were leaping from tree to tree. A stifling smoke
+filled the air, always in swift motion, but stifling still.
+
+
+
+
+CHAPTER V.--THE REVELATION OF A TRAGEDY.
+
+
+"Smugglers!" Frank exclaimed, dropping an armful of unopened opium tins
+on the floor of the cavern. "Smugglers, all right, all right!"
+
+Ned looked the tins over carefully. They were well covered with Chinese
+characters, and were dirty, as if they had been hidden away in the earth
+for a long time.
+
+"Who would have suspected it?" Frank continued. "We are close to the
+British frontier, but, all the same, this seems to me to be an awkward
+place to land and store the dope stuff."
+
+"Where did you find it?" asked Ned.
+
+"There is a false back to that cupboard in the north wall," Frank
+replied. "When I knocked on the boards they gave forth a hollow sound,
+and so I tore one away. Hence the opium. And there are pipes there,
+too--just such pipes as one sees in the joints on Pell street, in little
+old New York."
+
+"You remember what Jimmie said?" asked Ned.
+
+"I remember a good many things the little rascal has said," was the
+laughing reply. "He's always saying something."
+
+"Well," Ned continued, "the boy was right when he expressed his opinion
+of the heelless footprints in one word."
+
+"Chinks!" grinned Frank. "Of course!"
+
+The boys now went over to the cupboard in the niche and began tearing
+away the boards. After a few had been displaced Ned stopped and began
+experimenting in fitting them in position again.
+
+"What's doing now?" demanded Frank.
+
+"We must remove them so as to be able to return them as we found them
+before we leave," Ned replied. "It is important that the inhabitants of
+this robber den do not know that we have discovered it."
+
+"Don't you ever think they don't know it right now," Frank said. "We
+haven't seen any of them since they rowed around the point, but they're
+stirring about, just the same. We may see more of them before we get out
+of this cavern."
+
+"Well," Ned said, "we must take all the precautions needful, and if they
+are of no avail we shall not be to blame for what takes place. Even if
+they know that we have found the cavern, they need not know that we have
+penetrated into the office chamber. Now, draw that last board away
+carefully, and we'll see what there is behind the false bottom."
+
+Frank drew the board away and was confronted by a long, low tunnel--an
+uncanny, narrow tunnel which had evidently been enlarged from a fault in
+the rock, and which appeared to penetrate far into the bulk of the
+mountain.
+
+"See!" he cried. "The cupboard was built at the mouth of a cross fault
+in the rock, and there is no knowing what is behind it. Hold your
+flashlight higher and I'll crawl in and look about."
+
+"Be careful," Ned warned. "I have seen great holes at the bottom of
+tunnels like that. Don't break your neck, or tumble down so far that I
+can't fish you out."
+
+Frank grinned and crept through the opening made by the removal of the
+back of the closet. The place was not high enough for him to stand
+upright, and so he proceeded on hands and knees.
+
+"This is a bedroom," he shouted back to Ned. "There's lots of ticks and
+blankets here."
+
+There was silence for a moment, and then the boy's voice came from
+farther in the tunnel. "And here's kegs of whisky," he cried. "It smells
+like a Bowery saloon. Come on in!"
+
+"I think one of us would better remain outside," Ned replied. "I
+wouldn't like to be surprised while in there and fastened in with
+rocks."
+
+Frank went on down the tunnel for some distance, calling back, now and
+then, to report his discoveries. There were weapons stored there,
+barrels of gasoline, packages of dynamite.
+
+Then, for several long minutes, there came no voice from the interior,
+and Ned put his head inside and called out softly:
+
+"Frank!"
+
+There was no reply, and Ned was about to advance into the opening when
+the sound of a footstep came on the rocky floor of the chamber just
+behind him. The footstep was a stealthy one, halting, as if some person
+were listening between the steps. Ned's first act was to shut the light
+off from his electric candle.
+
+Then he moved away from the niche in the wall where the cupboard had
+been built in and waited. His greatest fear was that Frank would turn
+about and show his light, and so expose them both to danger. While he
+listened, almost holding his breath, the steps came nearer to the
+cupboard and halted.
+
+But the halt was only for an instant, for the unseen figure moved on
+again, this time back toward the entrance. Directly the footsteps were
+heard no more, and then the crash of falling rocks reached the boy's
+ears. He did not have to think long in order to understand what that
+sound portended.
+
+He knew that they had been observed by some of the outlaws who made the
+cavern their home and their storehouse as well, had been followed into
+the inner chamber, and were now to be fastened into the cavern, probably
+left there to starve, with tons of rock bulking before the entrance to
+the third chamber. It was not a pleasant situation.
+
+While he studied the peril over in as optimistic a mood as was possible
+under the circumstances, he heard Frank calling to him from the narrow
+tunnel behind the cupboard. The boy was evidently excited, for his voice
+rang high.
+
+"Ned!" he cried. "Come on in!"
+
+The noise of falling, rolling rocks stopped at the sound of Frank's
+voice, and Ned thought he heard a half-suppressed chuckle in the
+darkness.
+
+"Hurry!" came Frank's voice once more. "There's something in here that
+takes the nerve out of me."
+
+There was a low exclamation of rage at the entrance, where the stones
+were piling up, and then the grind of falling rocks was continued. Ned
+had, of course, no idea as to how many persons were engaged in building
+up the wall which threatened to shut him in until life was extinct, or
+exactly how it was being done, but he knew that the correct thing for
+him to do was to prevent the completion of the work.
+
+If only one man had arrived at the cavern he might be frightened and
+driven away by a little shooting. With bullets whizzing through what was
+left of the opening, the man who was building the crude wall would not
+be likely to present his body before the space still uncovered. This
+reasoning brought the boy to a consideration of the matter of
+ammunition, but he decided that, with the cartridges carried by Frank,
+they could defend the place for a long time.
+
+But another question intervened. The rocks which, though unseen, he knew
+to be blocking the space where the rug had hung were undoubtedly falling
+from a distance. They might have been stored above the natural doorway
+for the very purpose to which they were now being put.
+
+If this were true, then the building of the trap would continue,
+regardless of his bullets. While he studied over this problem, slowly
+making up his mind to put it to the test, Frank's voice came from the
+tunnel again.
+
+"What's doing out there?" the boy asked. "Why don't you come in here?"
+
+"Shut off your light!" ordered Ned, as a glimmer showed inside.
+
+"Not me," replied Frank. "I need all the light I can get in here!"
+
+"What have you found?" asked Ned anxiously.
+
+Frank did not reply instantly, and Ned heard the rattle of stones while
+he waited for his answer. The task of piling up the wall was progressing
+rapidly, and it seemed to the boy that the stones were all falling from
+a distance.
+
+"Shut off your light and come out," Ned said, impatient at the
+hesitation.
+
+"I wouldn't stay here in the dark for a thousand dollars a second,"
+Frank replied, "but I'll come out. Why don't you show a light?"
+
+"I'm not looking for any chance bullets," Ned replied, coolly. "We're
+caught, my boy, and it is up to us to move cautiously. Why don't you
+turn off your light?" he added, half angrily.
+
+"Oh," Frank replied, "you're getting it out there, too, are you? Well, I
+was trying to save you a shock. There's a dead man in here, and I'm
+going to keep my light going until I'm out of the hole. I did shut it
+off once, and felt the grasp of a hand on my neck--and there wasn't any
+hand there either."
+
+"A dead man?" repeated Ned.
+
+"Sure," Frank replied. "And he's not been dead very long, at that."
+
+Again the boy heard that vicious chuckle at the entrance. Then a voice
+came out of the mouldy darkness:
+
+"How are you getting on in the Secret Service, Ned Nestor?" the voice
+asked.
+
+"Finely!" Ned called back, but it seemed to him that his voice shook
+with the peril of the situation. He was known, his mission there was no
+secret, the enemies of the government were already on the ground, ready
+to combat him in his work. Just how far their hostility would extend was
+evidenced by the fall of rocks outside. It seemed to the boy that the
+struggle would be to the death.
+
+"Who are you talking to?" Frank asked.
+
+Ned did not reply to the question, for there came the sound of a scuffle
+outside, then a shot, a cry of pain, and the cavern was still as a
+grave.
+
+In the silence Frank's movements were heard, and Ned knew that he was
+backing out of the tunnel, with his light still burning. Entirely at a
+loss to account for the fracas outside, Ned awaited his approach with a
+fast-beating heart. When at last he shut off his electric searchlight
+and dropped from the tunnel through the old cupboard Ned seized his hand
+and drew him away.
+
+"Did you fire that shot?" Frank whispered.
+
+"No," was the reply. "There's fighting outside, and the shot was fired
+there. Now, I had a notion of sending a stream of bullets through the
+doorway, but the persons who are fighting the man who came upon us here
+may be our friends, so we must be careful what we do. Here. Take my
+flashlight. Open the two at the same instant and turn the rays on the
+doorway. I'll be ready with my gun."
+
+But before this movement could be carried out a voice the boys knew came
+out of the darkness.
+
+"Wonder you wouldn't give a fellow a lift," Jimmie said, in a panting
+tone. "I've got to the limit with this big stiff."
+
+The lights were on instantly, with Ned and Frank bounding toward the
+opening. The way was narrow, for many rocks had been dropped down from a
+broad ledge just above, but they managed to crawl through. But before
+Ned could reach the struggling pair on the floor the under figure
+wiggled away, staggered for an instant, and then made for the outer air
+at good speed.
+
+Jimmie sat upon the stone floor with a disgusted look on his freckled
+face.
+
+"Now see what you've been an' gone an' done!" he cried. "You've let me
+pirate get away! But he took a bullet with him," he added.
+
+"How many were here?" asked Ned, shutting off his light and telling
+Frank to do the same. "How many men did you see?"
+
+"Just that one," Jimmie replied, sorrowfully, "an' he got away!"
+
+Ned advanced to the entrance and listened. At first he heard the sound
+of limping footsteps, then the sweep of oars. He ran down to the beach
+and swept his light over the waters of the lake. A slender boat was
+speeding far to the north, and a solitary rower was bending to his work.
+
+Now, for the first time, Ned noted that a fierce gale was blowing from
+the west, and his thoughts went back to the plateau where the aeroplane
+lay exposed to the storm. He ran back to the cavern, barely escaping
+being blown off his feet on the way, and called to the boys.
+
+"There's a stiff wind blowing," he said, "and I'm afraid for the
+aeroplane. We must get back to the camp immediately."
+
+"The wind was on when I came in," Jimmie said, "an' it near blew me into
+the lake, even if I did hold on to the trees. We can never make the hill
+in the storm."
+
+"We've got to," Ned insisted.
+
+"Besides," Jimmie continued, "we want to find out about the dead man
+Frank has been telling me about. We can't take him with us, an' he will
+not be here when we come back. Whatever we learn about him, an' the
+cause of his death, must be learned now."
+
+"Sometimes, Jimmie," Frank burst out, "you exhibit signs of almost human
+intelligence!"
+
+"The boy is right," Ned observed. "I'm so rattled that I hardly know
+what I'm about. We ought to be in pursuit of that rascal who is rowing
+on the lake, we ought to be on the plateau, looking after the aeroplane,
+and we ought to be here, finding out if a murder has been committed."
+
+"It is a murder, all right," Frank said, "for the floor in the tunnel is
+sticky with blood."
+
+"I'm goin' in there!" Jimmie exclaimed.
+
+"Go if you want to," Frank grunted.
+
+Ned laid a hand on Jimmie's arm as he started away.
+
+"If you don't mind," he said, "I'd much rather you remained on guard.
+You have keen eyes, and may be of great service here."
+
+"All right!" the boy said. "I'll do anything you ask me to if you don't
+leave me out of the game."
+
+"No danger of your getting into the dust heap," Frank laughed. "How long
+have you been prowling about here?"
+
+"Just a short time," was the reply. "I remained in the tent until I
+thought Pat an' Jack were asleep an' then cut my lucky. Say, but the
+wind was blowin' when I slid down the slope toward the lake."
+
+"It must be fierce up on the plateau," Frank admitted. "Say," he added,
+turning to Ned, "if you don't mind, I'll go on up the hill and help the
+boys with the aeroplane. It would be a tragedy if it should be destroyed
+now."
+
+"All right," Ned said. "Get up there as soon as possible. The boys may
+be having trouble with the 'plane. And Jimmie," he added, "suppose you
+keep an eye on the plateau? The lads may signal."
+
+"Too dark for that," the boy replied, "but I'll keep a sharp lookout,
+just the same. Go on and look over the man Frank found under the
+mountain."
+
+Frank moved on up the hill, clinging to trees as he advanced, and
+stooping low, even then, to escape the force of the wind, while Jimmie
+stationed himself in the opening and looked out on the lake. Ned
+disappeared in the cavern, and the boy saw his torch grow fainter as he
+climbed through the narrow opening left in the rock which had been
+thrown over the natural doorway.
+
+It was getting late and the boy was sleepy, but he struggled manfully to
+keep his eyes open. Directly, however, he had no trouble in this regard,
+for he started up with a strange, acrid odor in his nostrils. The
+low-lying sky was aflame.
+
+
+
+
+CHAPTER VI.--ABOVE THE CLOUDS AT NIGHT.
+
+
+The wind gained strength as the heat of the forest fires increased. The
+roaring of the gale and the heavy undertone of the racing flames
+effectually drowned the voice of the forester, and it was only by the
+motion of his lips that the boys knew that he was trying to talk to
+them.
+
+Presently he threw his hands high above his head, weaponless, then
+lowered one and beckoned to them. Still keeping grasp on their
+revolvers, the boys approached him. His face was deadly pale, save for
+the glow of the fire which shone unnaturally on the wall behind him.
+
+"This is no time for accusations," he shouted. "We must do something to
+check the fire."
+
+"What is to be done?" Jack demanded, half won over by the apparent
+distress of the fellow.
+
+"The blaze will burn itself out against the mountains," was the reply,
+shouted at the top of the speaker's lungs, "but the fire in the caņon
+must be checked by going on ahead and felling trees."
+
+"Won't it burn itself out there, too?" asked Pat.
+
+"I'm afraid not," was the shrill reply. "There is an opening from the
+top of the caņon to a valley in a fold of the hills. The fire will do
+incalculable damage if it passes through that."
+
+"What do you suppose we can do against a fire like that?" demanded Pat.
+"An army could not stop the blaze now."
+
+"You are mistaken!" shrilled the other. "Three choppers can clear a
+space which the fire will not cross."
+
+"We'll get our axes and try," Jack said, reluctantly.
+
+"Then make haste!" Greer shouted. "At all events we must leave this
+place, for the fire will soon be here. Come!"
+
+When the boys turned to verify this statement they saw that the planes
+of the aeroplane were red with the reflection of the blaze below, and
+that the creeping fire was already showing at the lip of the plateau.
+
+"The aeroplane is doomed, I guess," wailed Jack, and Pat thought he saw
+a look of satisfaction in Greer's face as the words reached his ears.
+
+The smoke was now rolling over the plateau in great clouds, but through
+it Pat thought he saw figures moving from the south slope toward the
+aeroplane. Calling out to Jack, he sprang toward the machine, the
+suspicion in his mind that these were confederates of the alleged
+forester, and that the machine was, after all, the main point of attack.
+
+Greer saw the movement and darted toward the boy as if to block his way,
+but Pat struck out viciously and turned him back. Then a bit of flame
+sprang up in the cloud of smoke which was sweeping over the plateau. It
+seemed to Pat that an attempt to burn the machine in advance of the
+arrival of the forest fire was being made.
+
+When he darted forward again Greer caught him by the shoulder and hurled
+him away.
+
+"Get your axes!" he shouted. "There is no time to waste here."
+
+Then the smoke lifted for an instant and Pat saw three figures rise
+above the rim of the northern slope and hasten toward the aeroplane.
+Their arrival there was followed by shots and calls for assistance. Then
+the smoke shut down again, and the roaring of the flames drowned all
+other sounds.
+
+Greer stood for an instant, braced against the wind, shielding his face
+from the hot blasts scorching the grass of the plateau, then turned and
+ran. Then both boys heard a call from the direction of the machine.
+
+"The way is clear to the cavern!" were the words they heard. "Remain
+there until we return!"
+
+"That's Ned," shouted Pat. "Just in time to save the aeroplane."
+
+Almost before the words were out of his mouth there came a lull in the
+wind and the great machine ran forward a few yards, then swung into the
+air. At that moment Frank came running toward the two astonished boys.
+
+"We've got to leg it!" Frank shouted, his mouth close to Jack's ear.
+"Drop low on the ground so as to get fresh air and run!"
+
+Jack, although he had heard Ned's voice giving directions, and although
+he knew that Frank was by his side, could hardly sense the situation, or
+all that had taken place. The action had been so swift that he could not
+yet realize that Ned had snatched the aeroplane away from certain
+destruction and lifted it into the stormy sky in so short a time.
+
+However, he did not stop then to place the events in neat order in his
+mind, for the fire was working across the scant vegetation of the
+plateau and the air was hot and stifling. It was all like a page out of
+the Arabian Nights, but he put the wonder of it away, grasped Frank's
+hand, and, crouching, ran toward the incline leading to the lake. There
+was safety there, at least.
+
+Now and then, in their swift flight, the boys stopped and looked upward,
+hoping to learn something of the fate of the aeroplane, but the great
+machine was not in sight.
+
+"Ned never can make it live in this gale!" Jack almost sobbed, when, at
+last, they all came to a halt at the margin of the lake. "The whole
+shebang will go to pieces and the boys will be killed."
+
+"Aw, forget it!" grunted Pat. "I'm not in love with airships, but I know
+that Ned wouldn't have gone up unless he knew that he could handle the
+machine. He'll lift above the divide and drive straight before the wind.
+The good Lord only knows how far the gale will take him, but I'm betting
+my head against turnips that he'll come back by morning, asking why
+breakfast isn't ready!"
+
+"How did you get wise to the trouble up here?" Jack asked of Frank.
+
+"Why, I don't exactly know," the boy replied. "Ned sent me on ahead to
+look out for the aeroplane. He said he wanted to remain in the cavern
+and investigate. I was making slow progress up the hill when Ned and
+Jimmie came running after me. I had noticed long before that the sky
+looked like fires were burning somewhere."
+
+"I should say so," Pat cut in. "The clouds looked like they had been
+soaked in red paint."
+
+"When Ned came up to me, running like a racehorse," Frank went on, "he
+said he was going to take the aeroplane out, wind or no wind. I didn't
+have much chance to talk with him, but I understood that he was going to
+do just what Pat has suggested--run before the wind and swing back
+whenever he could."
+
+"I presume Jimmie is good and scared by this time!" Jack commented.
+
+"When we got to the machine," Frank went on, "we found two men there
+with some sort of torches in their hands, trying to set the machine on
+fire. We caught them unawares and left them lying there. I hope they
+didn't get burned to death."
+
+There was a short cessation of speech while the boys listened to the
+roaring of the flames and watched the fire mounting into the sky. It was
+a wild scene--one calculated to bring terror to the breast of any human
+being. The wind was dying down a little, but the clouds were still
+driving fast before it, their edges tinged with flame so that they
+resembled golden masses floating across an eternity of space clothed in
+smoke.
+
+While the boys watched the great display Frank pointed to a wall of
+flame rounding the corner of the plateau.
+
+"The fire will burn this slope," he said, "and we've either got to get
+into the cave or out on the lake. Which shall It be?"
+
+"The cave for mine!" Jack cried.
+
+"And mine," echoed Pat. "Who knows what the fire will do to the lake?"
+
+But Frank had had previous experience in the cavern. He was thinking of
+the still figure he had found lying there, and of the dark stains on the
+floor.
+
+"If we could find a boat," he said, without mentioning his real reason
+for objecting to the cave, "we might get along very well on the lake. We
+don't know what stifling air we shall find in the cave, and, besides,
+the men we have just had a fracas with may return at any time. It
+wouldn't be nice to be locked up in that hole in the ground."
+
+The wind was dying down to a steady breeze, and the fires seemed to burn
+lower. The clouds above were dark and threatening, save where gilded by
+the reflection from below, and seemed to be massing. Frank held up a
+hand and shouted.
+
+"Rain!" he cried. "Rain!"
+
+It was no gentle spring shower that opened upon the earth then. The
+fountains of the great deep seemed to have opened wide. The water fell
+in sheets, and in an instant the boys were wet to the skin.
+
+"Better than fire!" Jack suggested.
+
+The rain pelted down upon the forest fires viciously, and the hissing
+protests of the angry embers rose in the air. Through the thick veil of
+the rain clouds of steam could be seen rolling over the lake and along
+the threatened incline. In ten minutes water was pouring down the steep
+hill in sheets and the fires were leaping no more.
+
+Pleased as the boys were at the opportune arrival of the rain-bearing
+clouds, they could not help wondering if the freak of chance which had
+preserved the forests of northern Montana had not brought Ned and Jimmie
+sudden death.
+
+"They never can handle the machine in such an air-ocean," Jack declared,
+but the more optimistic Pat asserted that Ned must have been a mile
+above the rain clouds before a drop of water fell.
+
+"I guess the fire brought this rain on," Frank said, wiggling about in
+his wet garments, "but it's just as wet as if brought about by some
+other means. What are we going to do now?"
+
+"Why not go to the cave until the rain stops?" asked Pat.
+
+"It is colder in there than it is here," Frank said, still thinking of
+the silent figure in the narrow tunnel back of the cupboard.
+
+"We can't get any more water in our clothes and hides than we have now,"
+Jack observed, "so we may as well stay outside and watch for Ned and the
+aeroplane. I don't believe any other person ever took an aeroplane up in
+such a storm. I'm afraid Ned was smashed against the divide."
+
+"Ned's all right," insisted Frank. "Suppose we go back to the plateau
+and see if there's anything left of our tents."
+
+"I'm game for that," Pat said, "but," he added, turning a keen gaze on
+Frank, "I'd like to know why you object to going to the cave. Jack and I
+would like to see it."
+
+"Well," Frank replied, not without some hesitation at bringing the scene
+in the tunnel back to his mind in form for expression in words, "there's
+a crime been committed in the cave, and it's uncanny."
+
+"A crime!" repeated Pat, all excitement at the suggestion of another
+adventure, "what kind of a crime?"
+
+"A murder," replied Frank, with a shiver.
+
+"Let's go in and see," Pat said.
+
+"Frank's afraid," Jack put in.
+
+"Of course I'm afraid," Frank admitted. "You go in there, and crawl on
+your knees through the thick air of a narrow tunnel, and put your hand
+on a dead man's face, and feel your other hand slipping in the blood on
+the floor, and you'll be afraid, too. I'm not going back there."
+
+"We can stand here in the rain all night, if you want to," Pat said,
+with scorn in his voice. "Rainwater is said to be good for the
+complexion."
+
+The wind was slowing down and the rainfall was not so heavy as before.
+The boys, Pat and Jack, joking Frank about his terror for the cave, and
+Frank just a little angry, began the ascent of the slope leading to the
+plateau.
+
+"The rain saved the trees next to the mountain," Pat said, presently,
+"and if it checked the fire on the plateau at the same line our tents
+are all right. Say," he added, "who ever heard of such a downpour as
+that. I reckon the rain swept in from the ocean in heavy clouds which
+were broken open by the mountains."
+
+"Much you know about it!" laughed Jack. "You talk as if you could cut a
+cloud with a knife."
+
+"Anyway," persisted Pat, "the water tumbled out and checked the fires.
+Wonder what became of the man who said his name was Greer? He was
+standing in with the men who were trying to burn the aeroplane, all
+right enough, and I believe the whole circus was started just to destroy
+the airship and bring Ned's investigations to a close."
+
+"We always do get into the thick of it at the first jump," Frank said,
+remembering the bomb under the cottage in the Canal Zone and the raid on
+the nipa hut in the Philippines. "Whenever we've got anything coming to
+us, we get it by lightning express."
+
+"You bet we do!" Jack exclaimed. "Now we're getting a clear sky," he
+added, pointing upward, "and we're getting it short order time, too!"
+
+The heavy clouds were gone, the moon was smiling down on the drenched
+earth, the stars were winking significantly toward a spot on the plateau
+where two unrecognizable figures, half burned away, were lying. When the
+boys reached the top of the climb and advanced to the spot where the
+aeroplane had stood they turned sick with the horror of the thing.
+
+"I almost wish we had let them destroy the aeroplane," sighed Frank. "I
+don't like to think that these men came to their death through us. It is
+awful!"
+
+"Did you shoot them?" asked Pat.
+
+Frank shook his head.
+
+"They shot at us," he said. "They fired as soon as we got to the rim of
+the dip, but missed because of the smoke and the wind. Then we rushed
+them, and they went down--to escape punishment, I thought--and so Ned
+got the aeroplane away."
+
+"Then you had nothing to do with their death," consoled Pat. "They came
+here to commit a crime and were overcome by the smoke and heat."
+
+Frank would gladly have accepted this version of what had taken place,
+but he could not bring his mind to do so at once. The horror of what he
+had found in the cave was still upon him.
+
+Leaving the spot where what remained of the outlaws lay, the boys
+hastened to the wall of rock which terminated the plateau on the east.
+The rain had indeed saved the tents from destruction. The canvas was
+huddled against the wall, stained with smoke and heavy with rain, but in
+fairly good condition.
+
+"We'll have to remain here, or about here, until Ned comes," Pat said,
+"so we may as well put the tents up. I wonder if it isn't most morning?"
+
+"Does that mean that you are getting hungry?" grinned Jack.
+
+"You bet it does!" was the reply. "Anyway, I'm going to see if I can
+find dry wood enough for a fire. If I can I'll make some hot coffee. Ned
+will see the fire, and know we are not in the cave."
+
+Then an exclamation from Frank called the speaker's attention to the
+clear sky over the divide. The upper strata of clouds were drifting
+westward on a high current of air--what few clouds there were--and far
+up in the blue, the moonlight trimming the planes with silver, rode the
+aeroplane, seemingly intact, and working back on the high current toward
+the Pacific coast.
+
+
+
+
+CHAPTER VII.--A KEY WITH A BROKEN STEM.
+
+
+The lights were burning low in a bachelor flat on a noisy street corner
+in the city of San Francisco, and a man of perhaps thirty lay on a couch
+with his eyes closed. There were in this sitting room, which faced one
+of the noisy streets, a grand piano, a costly music cabinet, a walnut
+bookcase filled with expensively bound volumes, numerous lazy chairs of
+leather, and the rug on the polished floor was rich and soft. The
+occupant of the flat evidently enjoyed luxurious things and had the
+money to pay for them.
+
+When a clock in a distant steeple struck midnight there came a knock at
+the locked door in the main corridor which connected with the private
+hallway on which the flat opened. A Japanese servant, small, obsequious,
+keen-eyed, opened the door, after the hesitation of a moment, and peeked
+out. He would have closed it again instantly, seeing a stranger there,
+only Ned Nestor, who had anticipated some action of the kind, thrust a
+shoe into the opening, and, reaching in, unfastened the chain.
+
+"I wish to see Mr. Albert Lemon," he said.
+
+The Jap tried to force the door back and lock it, but was unsuccessful.
+
+"No savvy!" he cried, as Ned brushed past him and stood in the private
+hall.
+
+Ned paid no further attention to him, but entered the sitting room and
+at once advanced to the couch where the man lay. The figure on the couch
+did not move, but the Jap forced himself in the boy's way with his cry
+of "no savvy!"
+
+"Opium?" Ned asked, pointing down to the man.
+
+"No savvy!"
+
+"Hit the pipe?" he asked, putting the question in a new way.
+
+"No savvy! No savvy!"
+
+"Dope, then?" Ned went on. "Tell me if this man has been doping himself
+into unconsciousness. Dope, eh?"
+
+Ned lifted his voice, half hoping that the man on the couch would show
+some signs of life, but there was no movement of the eyelids.
+
+"No savvy!" grunted the Jap.
+
+Ned took the servant by his shoulders, pushed him gently out of the
+room, and closed and locked the door, the key being in the lock on the
+inside.
+
+"No savvy! No savvy!"
+
+The words came through the thin panel of the door in quick succession
+for a minute and then silence. Again Ned advanced to the side of the
+couch and looked down upon the semi-unconscious man.
+
+It was clear to the boy that the fellow sensed what was taking place,
+but was too well satisfied with the drugged condition in which he lay to
+disturb his poise of mind by taking note of anything whatever. The
+figure of the fellow was dressed in expensive clothes of latest cut, but
+they were soiled, and even torn in places.
+
+The disreputable condition of the garments reminded Ned of a suit in
+which he had once been hauled through a briar patch and pulled into a
+pond at the hands, or horns, rather, of a village cow, assisted by a
+rope. His clothes, it is true, had not been expensive ones at the time
+of the occurrence, but the looks of the clothes the drugged man wore
+reminded him of the damage his cheaper ones had sustained.
+
+The face of the man on the couch was deadly pale, with the drawn look
+about the skin which comes of much familiarity with the drug made of the
+poppy. It was still an attractive face, even in its degradation, and the
+forehead was that of a capable man.
+
+Ned drew a chair to the side of the couch and sat down. Even if he
+should at that time succeed in attracting the attention of the man, the
+fellow was in no condition to answer the important questions he was
+there to ask.
+
+Presently the Jap, or some one else, came and rapped lightly on the
+door, and Ned opened it a trifle and looked out.
+
+"No savvy!" cried the Jap, repeating the words like a parrot, standing
+in the hall with many signs of fright on his yellow face.
+
+"All right!" Ned said, shutting the door in his face, "you don't have
+to."
+
+"I can't blame him for thinking this a cheeky invasion," Ned smiled, as
+he returned to his chair at the side of the couch. "It isn't exactly the
+thing to walk into a man's private room in this manner."
+
+Ned had decided to sit by the side of the half conscious man until he
+returned to his full mentality. Questions now might produce only pipe
+dreams, for the imagination is rather too active under such
+circumstances.
+
+Five days before Ned had left the boys in a cup on the western slope of
+the Rocky Mountains, not far from the summit, after explaining to them
+that he was going to the city to investigate a clue connected with the
+murder of the man who had been found in the cavern. Leaving the
+aeroplane safely hidden at Missoula, he had traveled by rail to San
+Francisco.
+
+In his handbag on this trip were two seemingly unimportant articles--a
+piece of tape cut from the inner side of the collar of the dead man's
+coat, and a small, odd-shaped key with the stem broken off so that it
+was only about an inch in length. The key had been the only article
+found in the dead man's pockets. The strip of tape bore the name of a
+San Francisco tailor.
+
+The directory had assisted him in finding the tailor, and the tailor had
+informed him that the coat had been made for one Albert Lemon, whose
+address he gave. So here he was, in Lemon's apartment, seeking
+information concerning the dead man, while Lemon, supposedly Lemon, lay
+in an opium daze on the couch.
+
+But Ned's time, waiting for the man to come back to consciousness, was
+not all wasted. Moving carefully about the room, he found that the
+broken key fitted a writing desk which stood between two windows. The
+lock which it fitted, however, was not in good condition, for the bolt
+had been pried back, damaging the polished edge of the casing which held
+the socket. The desk contained nothing of importance, and Ned left it as
+he found it.
+
+Sitting there in the soft light of the room, he did not know whether the
+man on the couch was Albert Lemon or whether the man who had died in the
+cavern was Albert Lemon. He believed, however, that the outlaws he had
+encountered in the mountains, had murdered the man, and felt that the
+surest way to trace the crime to them was to find out why the man had
+joined them--why he was there in the tunnel back of the cupboard. This
+would be likely to bring out a motive for the deed.
+
+He did not, of course, know whether the dead man had stood as an enemy
+to the outlaws, or whether he had stood as a friend. But that could make
+no difference with the quest he was on. He believed that the outlaws
+were the men he had been instructed to hunt down, and knew that proof
+could be obtained only by an intimate knowledge of their associations,
+their ways, their motives. The friends of the dead man he thought, would
+know something about them, perhaps be able to place them in the circle
+in which they lived when not in the hills.
+
+In work of this kind it is the first task of an investigator to "place"
+the man he is pursuing. The burglar is as good as taken when he is
+traced back to those he associates with in his hours of leisure. In the
+absence of a clue pointing to a person, the investigator busies himself
+in finding a motive. Ned believed that he now had the personal clue. The
+motive would place the proof in his hands.
+
+So his Secret Service work for the government was leading him into the
+investigation of a murder mystery. He smiled as he held up the key and
+wondered if the facts when discovered would bear out the suspicions in
+his mind. Again he asked himself the question:
+
+"Is this Albert Lemon, or was the dead man Albert Lemon?"
+
+After a long time the man on the couch opened his eyes and looked about
+the room. His glance rested for an instant on the figure in the chair at
+his side, but the fact of its being there did not appear to surprise him
+in the least.
+
+"Jap!" he called faintly.
+
+There was a sound at the door, but it was still locked, and the servant
+was unable to obey the summons.
+
+"Bring me a pipe!" were the next words.
+
+The Jap clamored at the door, but did not gain admission. The racket
+seemed to disturb the man not at all.
+
+"I think," Ned said, "that you have had all the dope you need to-night.
+Besides, I want you to answer a few questions."
+
+"Perhaps I have," the man said, "but, supposing that to be the case,
+where do you come in? You are a new one on me, and I hope you won't flop
+out of a window or go up through the roof, as some of the others have
+done. I want to have congenial company to-night. Who are you?"
+
+"Ned Nestor," was the quiet reply.
+
+"So," said the man on the couch. "I've heard of you--read about you and
+the Canal Zone in the newspapers. But you're only a kid. What about
+that?"
+
+"I can't help being young," laughed Ned. "Anyway, that is a fault I'll
+soon get over. We all have it at first."
+
+"And get over it too quickly," said the other, with a sigh. "Well, what
+do you want here?"
+
+"Are you Albert Lemon?" asked Ned abruptly.
+
+"Yes," was the reply, "I'm Albert Lemon. What about it?"
+
+The man was gaining mental strength every moment now, and seemed to
+sense the strange situation.
+
+"Stiles is your tailor?" the boy went on.
+
+"Look here," said the other, rising to a sitting position and passing a
+shaking hand across his brow, as if to brush away the fancies of the
+poppy, "when you convince me that you have a laudable interest in my
+personal affairs I'll be glad to answer your questions."
+
+Ned took the strip of tape from his pocket and held it out to the man on
+the couch.
+
+"Do you recognize that?" he asked.
+
+Lemon nodded coolly, but a look of wonder and alarm was growing in his
+bloodshot eyes, and his jaw dropped a trifle.
+
+"I still lack the proof of laudable interest," he said, with a twisting
+of the face intended for a smile.
+
+"Answer the question," Ned replied, "and I'll inform you of my interest
+in this article--and in you."
+
+"Yes, I recognize it as the private mark of Stiles, my tailor," Lemon
+answered, in a moment. "Where did you get it? If you insist on asking
+personal questions I must insist on the right to do the same thing."
+
+"I cut this private mark," Ned said, "from the collar of a coat found on
+the back of a dead man in Montana, somewhere near the main divide of the
+Rocky Mountains. Do you know how it came there?"
+
+"Yes and no," was the reply.
+
+"Kindly answer the affirmative proposition first," Ned said, with a
+smile.
+
+"Well," said the other, "about three months ago an old college friend of
+mine, one Felix Emory, came to me from Boston. He was in bad with his
+people, and was out of money. I took him in here and tried to brace him
+up. I couldn't do it. His moral stamina was gone."
+
+Lemon paused a moment, and, with a deprecatory smile, pointed to an
+opium pipe which lay on the rug near the couch.
+
+"I understand," Ned said.
+
+"I fed him, and clothed him, and introduced him at the club, and gave
+him every chance in the world to get a brace, but he fought me off. All
+he cared for was a pipe and a pill and a place to sleep it off."
+
+"And so you gave him up as a bad proposition?" asked Ned.
+
+"Not exactly. He wanted to go to the mountains on a hunting trip. Well,
+I thought it would benefit his health, so I rigged up an outfit for his
+use and let him go. You say the man was dead?"
+
+"Quite dead," Ned replied.
+
+"Too much poppy, I presume?" Lemon asked with an ashamed smile.
+
+"Too much steel," Ned answered, sharply.
+
+Lemon stared at the boy for an instant, his eyes more anxious than ever,
+and arose shakingly to his feet.
+
+"Do you mean that he was murdered?" he asked.
+
+Ned nodded.
+
+"Where?" was the next question.
+
+"I found the body in a cavern on the western slope of the Rockies," was
+the reply. "He had been dead only a few hours."
+
+Albert Lemon maintained a thoughtful silence for a time, during which
+Ned eyed his changing expression keenly.
+
+"And what do you wish me to do about it?" he then asked.
+
+"A crime has been committed," Ned replied, "and it seems to me that you
+ought to do all in your power to assist in bringing the criminal to
+punishment."
+
+"Granted, sir. Tell me what to do."
+
+"First, tell me about the men your friend went away with."
+
+"That brings me to the negative proposition," the other answered. "I
+have told you how Felix came by my coat, but I can't tell you whether
+the man the coat was found on was Felix. You must see that for yourself.
+He might have given the garment away, or he might have sold it in the
+city to get money for opium. In short, the coat might have been on the
+body of a man I never saw."
+
+"Then you can't tell me who Emory went away with?" asked Ned.
+
+"Certainly not," was the reply. "I don't know whether he went away at
+all or not."
+
+This was disappointing, but Ned had one more lever with which the man's
+indifference might be lifted, he thought. Before speaking again Lemon
+arose and turned the key in the lock of the door, against which the
+servant was still pounding. The Jap entered and stood by the door,
+looking intently at Ned.
+
+"When you gave him the suit of clothes he went away in," the boy went
+on, shifting his position so that both men would be under his eyes,
+"what articles, if any, remained in the pockets?"
+
+"Not a thing," was the reply. "I looked out for that."
+
+"Then anything discovered in the pockets of the dead man," Ned said,
+taking the key from his pocket and toying carelessly with it, "must have
+belonged to him?"
+
+Ned saw Lemon give a quick start at sight of the key. The Jap advanced a
+step as if to get a closer view of it. Then both men turned their eyes
+for an instant to the broken lock of the writing desk. Ned had gained
+his point. The men recognized the key.
+
+"Where is the body you speak of?" Lemon asked, presently.
+
+"Buried near the cavern in the mountains," was the reply.
+
+"Perhaps you can give me a description of the body," Lemon said. "I
+might be able to say, then, whether the man was Felix."
+
+"Look in the mirror," Ned replied, "and you will see there a fairly good
+representation of the dead man. About the same in height, in size, and,
+yes, in feature."
+
+"Then it must have been Felix," the other said. "His remarkable
+resemblance to myself has often been remarked. Poor fellow! I'm sorry
+that his end should come in so ghastly a form."
+
+There was a short silence, during which Lemon's eyes flitted from the
+key in Ned's fingers to the writing desk.
+
+"I said a moment ago," he observed then, "that I searched the pockets of
+the clothes before I gave them to him, or words to that effect. I
+remember now that I ordered Jap to do it. Did you obey orders?" he
+asked, turning to the servant.
+
+Ned saw the Jap give a quick start, then regain control of himself.
+Lemon, too, looked crestfallen for a moment, then addressed the Jap in
+another tongue.
+
+"I was talking in English," he said, "and forgot for the moment that he
+would not understand me."
+
+There followed a short conversation between the two, and then Lemon
+announced that the Jap had forgotten to look in the pockets of the
+clothes. Ned ignored the explanation and put the key in his pocket. He
+knew now that the Jap could understand English, and also that the key
+belonged to Albert Lemon, alive or dead.
+
+[Illustration: ILLUSTRATION No. 3]
+
+Lemon arose and, going to a table, secured a tobacco pouch and a book of
+cigaret papers. As he rolled a cigaret Ned observed that the middle
+finger of his left hand carried, just below the nail, a blue spot, as if
+he had been using a typewriter since cleaning his hands. Ned noticed it
+particularly, as he himself used a double keyboard machine and usually
+smutted that finger on the ribbon when he rolled the platen.
+
+"Well," Lemon said, "I'll have to ask you to excuse me now. I've been
+off on a long country tramp. You see how mussed up I am. I think I
+crawled through briar patches and wire fences and fell into cow ponds."
+
+Ned turned away without a word, with plenty of food for thought in his
+mind.
+
+
+
+
+CHAPTER VIII.--FATE OF THE STEAK A LA BRIGAND.
+
+
+Jimmie lay stretched at full length under one of the discolored shelter
+tents in a little cup in the heart of the Rocky Mountains. Frank and Pat
+and Jack were moving restlessly about, looking up at the blue sky
+expectantly. Ned had not returned from his trip to San Francisco, and
+the boys were anxious as to his safety.
+
+"He should have taken me with him," Jimmie drawled, presently, when
+Frank threw himself down by the tent. "Then he'd have been all right."
+
+"It is a wonder that he got along in the world at all before he fell
+under your protecting care," Frank replied, with a grin.
+
+"Oh, he managed in some way," Jimmie answered, "but he never got up in
+the world until he took me into partnership," with a wink at his chum.
+
+"He's been up in the world since then, all right," Frank said,
+suggestively.
+
+"Too high up," Jimmie grinned. "Too high up for me, anyway. I thought
+I'd die up there, on the night of the fire."
+
+"In all the history of air navigation," Frank observed, soberly, "there
+was never a trip like that. When I think of the quick start, and the
+wind and the rain, the whole thing seems like a dream. How did he ever
+do it?"
+
+"I don't know," Jimmie replied. "He boosted me into the seat, and the
+next I knew we were off, an' the fire was dropping away from us, an' the
+mountains were growing smaller, an' the peaks looked like warts on the
+world. I felt like I was fallin' over the edge of somethin'."
+
+"And the wind?" questioned Frank. "Didn't it take your breath away?"
+
+"Wind, nothin'," the boy said, scornfully. "There wasn't any wind where
+we were. We went along with it. It was like sailin' on a swift stream.
+Ned tuned the engine up to keep steerway, an' shut his teeth. Then, in
+half a minute, we were above the clouds, an' the moon an' stars were
+askin' what we were doin' up there."
+
+"You're saying it well," Pat said, joining the little group. "If you
+were going so merrily before the wind, why did he want steerway?"
+
+"You don't know much about the atmosphere," laughed Frank, answering for
+Jimmie. "If you did, you'd know that the air blanket of the earth is a
+good deal like a river. It has eddies, and currents, and ripples, and
+holes, too."
+
+"You're good, too!" exclaimed Pat. "Holes in the air is about the best I
+ever heard!"
+
+"Of course there are holes in the air," Frank replied, with the air of
+one imparting valuable information, "especially when there are fires
+beneath. And, let me tell you this, you old red-head," he added, with an
+exasperating grin, "when the air, driven swiftly by the wind, or what we
+call the wind, comes to mountain peaks, and tall trees, and
+sky-scrapers, it just backs up, just the same as water does when it
+comes to a dam, or any obstruction."
+
+"Go it!" Pat cried. "Make it a good one! Where does this air go when it
+backs up?"
+
+"It just hunches up," Frank replied, gravely, "and checks the flow back
+of it, and then eddies and swirls away, fit to twist an aeroplane into
+kindling wood."
+
+"Of course," broke in Jimmie. "I've often read of aeroplanes dropping a
+thousand feet into holes in the air, and of their being swept against
+tall trees and buildings by eddies. It takes a cool head to run an air
+machine in a storm of wind, and that is where Ned won out."
+
+"If he hadn't kept the aeroplane going with the wind at full speed,"
+Frank added, "he would have been in a wreck the first half mile."
+
+"The more I learn about the atmosphere," Pat said, "the less I like it.
+When you get me up in an aeroplane, just send word to the folks that I'm
+tired of life."
+
+"Ned ought to have a Carnegie medal for what he did that night," Jack
+remarked, "and I'm going to speak to father about it when I get home."
+
+"There is no doubt that he ought to have one," Frank said, "but the men
+who really deserve Carnegie medals never get them."
+
+"You're an anarchist!" roared Pat.
+
+"All right," was the sober reply, "but if I had the giving out of the
+medals I'd present them to men who work twelve hours a day and provide
+for families of eight on nine dollars a week--the men who never get
+rested, and who never have enough to eat. They are the ones who ought to
+have the medals."
+
+"Most of them would sell the medals," Jack said, cynically.
+
+"Well," Frank replied, "I shouldn't blame them if they did. I'd rather
+have a porterhouse steak in the interior than a piece of bronze on the
+outside."
+
+"Don't talk about porterhouse steak!" pleaded Jimmie.
+
+"Hungry, little man?" asked Pat.
+
+"Hungry! I'm like one of the men Frank has been telling about. I never
+get rested, never have enough to eat."
+
+The boys fell upon Jimmie and rolled him out of the tent.
+
+"You get busy with fuel," Pat said, after they had given him plenty of
+"movements," "and I'll cook a steak ā la brigand."
+
+"We ain't got no steak," complained Jimmie.
+
+"We've got potatoes, and bacon, and onions," Pat said, "and canned
+beefsteak. You just watch me. I used to cook steak ā la brigand in the
+Philippines."
+
+"Get busy, then," Jimmie said, "and Jack will help get the green wood."
+
+"If you bring green wood here for me to cook with, I'll roast you over
+it," Pat said. "You get a lot of good dry wood that will make coals, and
+I'll show you how to broil a steak ā la brigand."
+
+"Why do you call it a brigand steak?" asked Jimmie.
+
+"Because it takes a red-headed brigand to cook it," suggested Jack,
+dodging out of Pat's reach.
+
+"Never you mind the name," Pat replied. "Get the dry wood and I'll broil
+a steak that will melt in the mouth."
+
+"That old canned stuff?" asked Frank.
+
+"Get the wood," ordered Pat, "and I'll show you."
+
+There were a few dead trees--the sole reminders of a former forest fire
+in that green valley--close at hand, and the wood was soon gathered and
+placed in a great pile near two rocks which Pat had rolled to within a
+yard of each other.
+
+"Here!" Jack called out, as Pat transferred the whole supply to the
+space between the stones, "there's enough fuel there for a week's
+cooking. Quit it!"
+
+"My son," Pat replied, with a provoking air of patronage, "what you
+don't know about broiling a steak ā la brigand would make a
+congressional library."
+
+While the wood was burning down to coals, Pat cut a green slip about an
+inch in diameter at the bottom and peeled and smoothed it nicely.
+
+"Is that to be used to enforce the eating of the steak?" asked Frank,
+winking at the others.
+
+"To keep you from gorging yourselves," Pat replied, going on with his
+work.
+
+In a short time he had the potatoes cut into half-inch slices. Jack had
+peeled them and, following directions with many grins, had also cut a
+round hole an inch in size in the middle of each slice.
+
+"He's going to wear 'em around his neck, like beads," Jimmie suggested,
+looking carefully over the heaped-up dish.
+
+The bacon was now sliced thin, as were the onions, and in the center of
+each slice a round hole was made. Then Pat opened a couple of tins of
+beefsteak--so called by the packers--and cut a hole in the middle of
+each slice. Then he strung a slice of potato on the spit, then a slice
+of bacon, then a slice of onion, then a slice of beef, until there was
+nearly a yard of provisions.
+
+"I begin to feel hungrier than ever!"
+
+Jimmie was dancing around the fire as Pat turned the spit. There were
+only coals now, and Pat kept the toothsome collection turning slowly, so
+as to broil without scorching. The smell of the cooking bacon and onions
+set the boys to getting out the tin plates and making the coffee.
+
+The sun, which had been shining fiercely all day, now seemed to be
+working his way through a mist. The atmosphere appeared to be tinted
+with the yellow haze one sees in the northern states in autumn.
+
+As the boys were keeping watch for Ned and the aeroplane, they noticed
+the change in atmospheric conditions, but attributed it to the rising
+vapor brought out by the heat of the sun.
+
+"Say," Jimmie said, presently, "I smell smoke. I wonder if there's goin'
+to be another forest blaze here?"
+
+"Of course you smell smoke," Jack said, watching the broiling supper.
+"We're cooking a steak ā la brigand, ain't we?"
+
+"Smells like burnin' leaves," Jimmie insisted.
+
+"More like onions," Pat observed.
+
+The boys crouched about the fire for some moments longer and then Jimmie
+arose and began to climb the wall of the cup to the west.
+
+"I'm goin' to see about this," he said.
+
+Frank laid a hand on his arm.
+
+"You wait a minute," he said. "You can't climb that slope in less than
+half an hour, and Ned will be here before that. Look! He's coming now,
+like the wind!"
+
+The aeroplane, high up in the hazy sky, was indeed making good progress
+toward the little cup in the mountain side. While the boys looked they
+saw it shift away to the west, whirl back to the east, dart off to the
+north and back again.
+
+"He's huntin' for us," Jimmie said.
+
+"He's investigating!" Frank cut in.
+
+"Investigating what?" Pat demanded. "He's smelling of this steak ā la
+brigand and is hunting for it. Let be. He'll find us."
+
+The sky was growing more uncertain every minute, and puffs of smoke were
+seen out in the west, over the rim of the cup.
+
+"The world is on fire, I tell you!" Jimmie cried, presently. "That's
+what Ned is shiftin' about for. If the blaze wasn't high up on the
+mountains we couldn't see the columns of smoke over the rim of the
+valley."
+
+"Well," Pat observed, "the fire can't get in here. Nothing to burn."
+
+"It can fill the cup with hot air and scorch us to death," Frank said,
+uneasily. "I think we'd better be looking about for a place to crawl
+into."
+
+"Wait until Ned comes," Jimmie suggested. "He'll know what to do."
+
+The aeroplane acted badly in the currents caused by the burning forest,
+but Ned finally managed to bring it down in the valley. The boys
+gathered about him, all excitement, and the steak ā la brigand was for
+the moment forgotten in the joy at the return of the patrol leader and
+the anxiety to learn something of conditions out in the woods.
+
+"It's going to be a great conflagration," Ned said, "but I think the
+aeroplane will be safe here. The whole slope is on fire."
+
+"I wouldn't take chances on leaving it here," Frank advised. "I'd jump
+over the divide with it."
+
+"I have been in the air three hours now," Ned replied, "and must have a
+rest. Besides, we must remain where we can, if necessary, help head off
+the flames. That is what we are here for, remember."
+
+"Not to fight fires," corrected Frank, "but to find out who sets them."
+
+"Anyhow," Ned replied, "we must fight the fire, if it gives us a chance,
+now that we are here. Now, what do you think that is?" he added, as a
+chorus of howls and cries came up from the slope on the west.
+
+"Sounds like a country circus!" Jimmie laughed.
+
+"That is just what it is!" Ned exclaimed. "Here! Help me roll the
+aeroplane into that nook, where it won't be trampled into splinters. Now
+you boys get behind it, and I'll get in front. Whatever you see or hear,
+don't shoot unless you are actually attacked."
+
+The boys obeyed the commands without a word of comment, well knowing
+what was coming next. A breeze was sliding up the slope, bringing with
+it flying masses of smoke. Presently birds began to stagger through the
+heavy atmosphere, flying low, almost within reaching distance, as they
+had fled long before the mounting flames and were exhausted.
+
+"I wish this would let up a moment," Pat said, "long enough for us to
+reach that steak ā la brigand. It must be about done by this time."
+
+"I'll go an' get it," volunteered Jimmie. "An' eat most of it on the way
+back."
+
+"Then bring the coffee," cried Jack.
+
+"Why can't we all go out there and eat?" asked Frank.
+
+The boys were about starting with a rush when Ned caught two of them by
+the arm and stopped the others by a quick call. Through the smoke and
+the hot air on the rim of the cup, a great head, a head neither white
+nor black, but grizzly, was seen. Then a deer bounded over and crouched
+down in the valley. Next two mountain lions raced over the lip of the
+valley and halted growling, within a few yards of the boys.
+
+"There goes our steak ā la brigand!" Jimmie cried, as the rush of
+frightened animals showed under the smoke. "I'll eat one of them deer to
+pay for this," he added.
+
+"You'll be lucky if one of these wild animals doesn't eat you," Jack
+said. "How would you like to be back in little old Washington Square
+just now?"
+
+"Forget it!" was the boy's only reply.
+
+"Will the fire get here?" Frank asked of Ned, as the wild creatures of
+the forest poured into the valley, regardless of the presence of the
+boys, unmindful of the proximity of each other.
+
+"I don't think the flames will come into the cup," Ned replied, "but if
+the smoke settles here we shall have a hot time of it."
+
+"Huh!" Jimmie cried. "The whole valley is full of mountain lions, an'
+bears, an' deer, an' snakes, an' rabbits. There ain't no room for any
+smoke!"
+
+Then the smoke rolled away for an instant, showing a sun as red as a
+piece of molten iron; showing, too, a huddle of forest animals crowding
+together in the center of the valley. In their terror of the fire they
+had forgotten to be afraid of mankind--of each other!
+
+
+
+
+CHAPTER IX.--THE CHAOS OF A BURNING WORLD.
+
+
+That was a day long to be remembered in the Great Northwest. It is true
+that the destruction of life and property at that time by no means
+equaled the ruin wrought by the forest fires of August, 1910, but the
+conflagration was serious in its final results for all that.
+
+In August of the previous year half a hundred persons lost their lives
+in the fierce fires which swept over portions of Idaho and Montana, and
+more than six billion feet of lumber were destroyed. At that time wild
+animals raced into the log houses of settlers in order to escape the
+flames. In one instance, placed on record by a forester, a mountain lion
+actually sought shelter under a bed.
+
+In that case, too, the fire virtually held its ruthless way until it
+burned itself out, as there were no trails, no telephones, no provisions
+for the fire fighters. The men of the forest patrol were each guarding a
+hundred thousand acres. In the more civilized countries of Europe, a
+thousand acres is considered a large district for one man.
+
+It was hot and close in the odd little valley on the mountain side.
+There seemed a premonition of greater danger in the very air--the
+lifeless air which seemed to dry the lungs beyond power of action. The
+wind, coming over the blazing forests, struck hot upon the face and
+scorched the lips, while the acrid smoke filled the eyes, the ears, the
+nostrils.
+
+It seemed to Ned that everything east of the Kootenai river must be on
+fire. Now and then, drawn by some wayward current of air, the thick
+smoke lifted in the little cup-like valley, and the cowering wild
+animals could be seen, huddling together in the terror of the time, deer
+no longer afraid of lion or bear, lion and bear forgetting to mark their
+prey.
+
+Finally, anxious to know the extent of the disaster, so far as it might
+be judged by a personal view of the country west of the valley, Ned left
+the boys in charge of the aeroplane and crept toward the rim of the cup.
+Jimmie saw him leaving and started on after him, but Jack drew him back.
+
+"Let him go alone, for once," Jack said, "he's only going to find out
+where this menagerie of wild animals comes from."
+
+Jimmie settled sullenly back by Jack's side, resolved to break away at
+the first opportunity and follow the patrol leader.
+
+When Ned gained the elevation he sought, the procession of wild animals
+had come to an end, although birds, frightened and singed by the flames,
+were calling from the sky. Everywhere rolled billows of smoke, blown on
+ahead of the line of fire and in a measure concealing its fatal advance.
+
+Now and then, however, a spurt of hot wind came over the burned waste
+and lifted the curtain for an instant. Then the boy saw that the fire
+was crawling up the slope, not racing as it had earlier in the day, but
+moving steadily, sweeping the earth of the undergrowth, but leaving many
+large trees.
+
+The danger was decreasing there, but lower down the flames were
+consuming everything in their path, eating down great trees and leaving
+fiery, straggling columns to consume them to ashes. Ned thanked his
+stars that the growths on the slope were not dense enough to foster such
+a blaze as that which burned below.
+
+It has been stated by those who know that ordinary care would have
+prevented most of the devastating forest fires which have raged in the
+Northwest. Experts claim that forests should be burned over under
+careful supervision, every three or four years. This, they say, will
+prevent the accumulation of inflammable material such as caused the
+terrible losses of August, 1910.
+
+Ned saw at once the expediency of the proposed remedy. He knew that
+resinous spines, steeped in the drippings of pitch and turp from the
+overhead branches, had lain many inches deep around the trunks of the
+trees, beneath fallen boles, and at the roots of the undergrowth. This
+accumulation made the extinguishing of forest fires impossible. He
+understood that the government had virtually provided for what followed
+by permitting this material to accumulate year after year.
+
+It is declared by foresters and others who strove to check that wall of
+fire that it advanced at the rate of a mile a minute between the
+Kootenai river and the foothills. Below where Ned lay was a burning
+furnace. It was so hot that he dare not lift his face a second time, and
+so he moved back to the aeroplane, which he found still safe from the
+flames, and the wild creatures crouching in the center of the valley.
+
+"What are the prospects?" Frank asked, speaking with his lips close to
+the ear of the patrol leader, for the roaring of the flames rendered
+ordinary conversation difficult.
+
+"There is safety here," Ned replied, "but everything to the west seems
+to be burning."
+
+"Gee!" Jimmie cried, looking Ned in the face, "how would you like to
+meet a friend with a basket of ice?"
+
+"Ice wouldn't last long here," Frank said.
+
+"Not if I got hold of it!" Jimmie grunted.
+
+As the line of fire came nearer to the top of the slope the air grew
+hotter, the smoke denser and more stifling. Pat remembered that a pail
+of water from a spring had been brought to the vicinity of the aeroplane
+soon after Ned landed, and the boys wet their handkerchiefs and bound
+them over their eyes and mouths.
+
+As the heat increased the wild creatures crowding together ominously.
+When a feeble beast was trampled by a stronger one, or when a rattler
+struck at the leg of a bear or deer, there was a cry of pain and a quick
+milling of the pack.
+
+"If this doesn't end soon," Frank shouted to Ned through his
+handkerchief, "there will be a stampede here. Then it will be all off
+for us."
+
+Ned looked around the little circle before replying. The boys certainly
+looked like "white caps" with their sheeted faces.
+
+"We'll have to wait and hope for the best," he said. "If the animals
+come this way, we must stop them, so far as we are able, with our guns
+and electric flashlights."
+
+Presently night fell, and the wind quieted a little at the setting of
+the sun. In a short time the clouds rolled away in sullen, threatening
+groups, and the stars looked down on the forest tragedy. Later, there
+would be moonlight.
+
+"I wonder if all the world is burned, except just this mountain?" Jimmie
+asked, taking the handkerchief from his face and wiping the smoke out of
+his inflamed eyes. "It looks that way."
+
+"There seems to be enough left to hold a lot of heat," Jack said. "I
+don't believe it will ever be cool again."
+
+"If we'd only saved that brigand steak!" wailed Jimmie.
+
+With the half light and the cooler air there came a commotion in the
+mass of forest creatures in the center of the valley. It was night now,
+and they seemed to feel the mounting of their wild instincts to be up
+and away on the hunt.
+
+Under the stars, one by one, they slunk away, bears and mountain lions
+turning sullenly toward the lesser beasts, but still too terrified by
+what they had passed through to feel the pangs of hunger. In half an
+hour the menagerie had vanished, some to the mountain, some over the
+slopes to the north and south. The boys drew long breaths of relief when
+the shambling figure of the last bear disappeared.
+
+Once Jack drew his gun on a fat old buck who seemed desirous of
+investigating the aeroplane, but Ned saw the action and checked the
+slaughter.
+
+"Let him alone," he said. "He's lived through this hell on earth, so
+give him one more chance."
+
+The boys now began gathering up their scattered utensils, restaking the
+tents, and preparing supper. Jimmie proposed another brigand steak, but
+Pat insisted that he never wanted to get near enough to a fire to cook
+again, so they made an indifferent meal of biscuit and tinned pork and
+beans, not even going to the trouble to boil coffee.
+
+While they were eating a gunshot came from the east, followed by the
+challenge of a chanticleer.
+
+"What do you know about that?" demanded Jimmie.
+
+"I suppose," Jack complained, "that we've been eating a picked-up supper
+within a few rods of a farmhouse, or cattle ranch!"
+
+"You might pry open some of the rocks back there," Pat observed, with
+sarcasm, "and see if you can find the house you speak of. It was a human
+throat that crow came from."
+
+"Sure it was!" cried Jimmie. "It was a Boy Scout call. Now just see me
+get him to talking."
+
+"What's a Rooster patrol chap doing here!" asked Jack. "I guess we are
+all having bad dreams."
+
+Jimmie did not reply. Instead he put his hands to his throat and in a
+second a long snarling wolf cry came forth, rising into a shrill call,
+as if summoning a pack at a distance.
+
+"We'll see what he knows about that," the boy said.
+
+As they listened the challenge of the chanticleer came once more. This
+time Jack answered it with the growl of a black bear, which seemed to
+Frank to be a great improvement on his practice stunts in the Black Bear
+Patrol club rooms in New York.
+
+This odd exchange of greetings kept up for some moments, and then the
+figure of a boy of perhaps seventeen was seen in the uncertain light,
+making slow progress down the mountain, a short distance to the north.
+He carried a haversack on his shoulders and was dressed in the khaki
+uniform of the Boy Scouts of America.
+
+"He must be used to mountain work," Jack remarked, as the boy leaped
+lightly from ledge to ledge and finally dropped into the valley. "I
+couldn't do that, even in broad daylight, to save my life!"
+
+The stranger now advanced to the group of boys and gave them the half
+salute of the Boy Scouts, standing with right arm straight out from the
+shoulder, palm outward, three fingers standing vertical, the thumb
+crossing the palm to rest on the bent-in little finger. Ned replied with
+the full salute, which is made with the hand in the same attitude, only
+at the forehead.
+
+"What does the badge say?" demanded Jimmie.
+
+"Be prepared!" was the quick reply.
+
+"For what?" was the next question.
+
+"To assist those in distress."
+
+"You're all right," Jimmie shouted. "What patrol?"
+
+"Chanticleer, Denver," was the reply.
+
+"That accounts for the way you lighted down from the mountain," laughed
+Ned.
+
+"I've got used to climbing in walking the streets of my home town,"
+smiled the other. "Is Ned Nestor here?" he added. "My name is Ernest
+Whipple; I'm looking for Mr. Ned Nestor."
+
+"Here he is, the only good-looker in the bunch," Jack laughed, pushing
+Ned forward. "What do you want of him?"
+
+"My father is connected with the Secret Service at Washington," was the
+reply, "and he posted me as to what was going on here. Said I might come
+out and join the party, if Mr. Nestor would permit it. What do you say?"
+
+Of course the son of a man connected with the Secret Service at
+Washington--a man who undoubtedly knew all the plans of the men who had
+sent Ned into the Northwest--was not to be ignored, but at the same time
+Ernest would have been received into the party on the strength of his
+own engaging personality, his own frank manner. From the very first
+moment he was a favorite with all the boys.
+
+"You're as welcome as the flowers of May!" Frank cried. "Been to
+supper?"
+
+"Last night!" grinned Ernest. "My haversack is empty--also my stomach. I
+had to take to the mountain in order to keep out of the fire, and
+couldn't connect with a grub stake."
+
+"Then there are fires east of the divide?" asked Ned.
+
+"Sure," was the reply, "although they are nothing like the ones over
+here. The foresters are watching them, and there is little danger of
+their getting a big start."
+
+"Where did you find foresters?" asked Ned, wondering if the men who had
+sneaked away from the cavern were not posing as foresters waiting to do
+further mischief.
+
+"They are in camp beyond the summit," was the reply. "They told me they
+had patrols all through the lower levels."
+
+Jack gave a description of the man who had visited the camp on the
+plateau, and was not at all surprised when Ernest identified the fellow
+as the apparent leader of the band of foresters he had passed on his way
+west.
+
+"I see that you don't believe the men are foresters," Ernest said,
+looking into Ned's anxious face. "Well, to tell the truth, I doubt it
+myself. I heard some talk there that set me thinking, after I got away.
+There was a man there who had just arrived from San Francisco, they
+said, and he was doing a good deal of kicking about something that had
+been done, or hadn't been done. I don't know which."
+
+"Can you describe the fellow?" asked Ned, a quick suspicion coming to
+his mind.
+
+"Of course I can," was the reply, and the remainder of the answer gave
+an accurate word photograph of one Albert Lemon.
+
+Ned was thinking fast. How had Lemon reached the eastern side of the
+divide so quickly. He, himself, had traveled swiftly from San Francisco,
+leaving soon after his exit from the bachelor apartment where the
+strange and not entirely satisfactory interview had taken place. He had
+left the man who claimed to be Albert Lemon half dazed and weakened from
+the effects of opium--still weary from a long and exhausting journey, as
+shown by his clothing, and yet the fellow had beaten him out in the race
+to the mountains.
+
+Why? Certainly not to take charge of the body of his unfortunate friend,
+for the grave was not there, but in a little hollow away to the north
+and near the lake. His business seemed to lie with the outlaws who had,
+apparently, committed the crime. Why? Had the man been killed as the
+result of a conspiracy between the two interests?
+
+This point was worth looking into, for the motive for the deed might
+also prove to be the motive for other crimes--among them the burning of
+forests.
+
+
+
+
+CHAPTER X.--CHASING THE MILKY WAY.
+
+
+While the boys were exchanging experiences with Ernest Whipple, talking
+over Boy Scout matters and arranging for a sleeping place for the
+stranger, Ned was busy with his aeroplane. It had not suffered in the
+least from the heat and wind, and there was plenty of gasoline on hand
+for a journey which he was thinking of taking.
+
+"Where are we goin' to-night?" Jimmie asked, finally, strolling over to
+the spot where the great bird lay.
+
+"As the wind is right," Ned laughed, "I thought I'd take a sail over the
+divide and see what the alleged foresters are up to."
+
+"All right," the boy said, "just wait until I get a big blanket to wrap
+up in and I'll go with you."
+
+Ned smiled at the determination of the lad to keep close to his side. He
+knew that Jimmie dreaded the very idea of leaving the solid earth that
+night, still he found him willing to make the ascent merely for the sake
+of being in his company.
+
+"All right, kid," he said. "You may go if you want to, but it may be
+morning before we get back to camp."
+
+"You can't remain in the air all that time," Jimmie said.
+
+"I am fully aware of that," Ned replied, "but I can drop down over on
+the other side and rest and tinker with the machine--if she doesn't work
+just right."
+
+"You haven't got gasoline enough," urged Jimmie, who would have argued
+Ned out of the notion of the night flight if possible, but who was
+determined to go with him if he went.
+
+"The first thing I do," Ned replied, "will be to fly over the Great
+Northern right of way and fill up with gasoline. Besides filling the
+tanks, I shall carry a lot away in an aluminum keg I have provided for
+that purpose."
+
+"Well," Jimmie said, with a tired sigh, "I should think you'd been
+through enough to-day and to-night, without goin' off in the dark, but
+I'm goin' if you do."
+
+After talking with the others regarding his intentions, and warning them
+to keep a sharp lookout during his absence, Ned assisted Jimmie to his
+seat and the two were away. There was scant room for a rise between the
+spot where the machine lay and the foot of the range, but Ned had little
+difficulty in getting into the sky and swinging along in the breeze.
+
+It was now after ten o'clock, and the moon was high in the heavens. To
+the east the dark passes of the mountains showed green and misty in the
+moonlight. To the west the burned spaces looked dark and forbidding,
+with smoke half hiding the ruin that had been wrought. Jimmie clung to
+the machine and insisted that Ned was chasing the Milky Way when he
+lifted the aeroplane up the level of the divide.
+
+Before crossing the divide, however, Ned flew to the Great Northern
+right of way and filled his tanks with gasoline, also filling the extra
+keg. The machine, which was an improved Wright, was then turned to the
+north-east. So perfect have aeroplanes now become that even
+inexperienced drivers may sometimes venture into the air with them with
+impunity, still it is well known that it is more the man than the
+machine that decides whether there shall be a tumble or a successful
+flight.
+
+The aeroplane is a wonderful invention, yet the point which really makes
+it so serviceable is a very simple one. For years inventors studied ways
+of making a heavier-than-air machine sail through the sky like a bird.
+Then the gasoline engine came, and all the rest seemed easy.
+
+But no one could keep control of the aeroplane. It moved about according
+to its own whims, and tipped drivers out at its own sweet will. Then the
+Wrights thought of lifting and lowering the planes to represent the
+wings and feathers of a bird. The secret had been found and required
+only experience and practice. Here was a machine light enough to fly,
+yet strong enough to carry with safety its powerful engine and two or
+more passengers, if there is room provided for them.
+
+It is so stout that a man may walk over it while it lies on the ground,
+and yet so delicate in control when in the air that a slight pull on a
+lever will dip one wing, lift the other, and at the same time turn a
+vertical tail-rudder about to give the necessary balancing pull with
+almost the instinctive adaptability of a bird's wings and feathers.
+
+And this wonderful machine, while speeding through the air with the
+velocity of an express train, can be halted almost instantly and whirled
+about on its tail. It will be seen that it is the man at the levers who
+makes or breaks a journey in the air. One man may do almost anything
+with a machine, while another may send himself to eternity with the same
+one. It was Ned's good fortune that he was naturally ingenious and quick
+to make his hands follow the impulses of his brain.
+
+When a person is thundering through the air, a thousand feet above the
+earth, he must remain perfectly calm, even with the engine thundering
+behind his ears, tears running in streams down his face, and the wind
+fluttering his clothes into rags and ravelings, as he wishes he was back
+on land.
+
+Besides, there are no level plains in the air, as there are on earth.
+Every bird-man knows that he is liable to come up against a fierce
+current or tumble into a hole in the atmosphere at any moment. While
+traveling in water one can see what is ahead and on both sides, but this
+is not so in the air. The currents, swirls, eddies, holes, do not show
+at all.
+
+When Ned left the caché where the gasoline and provisions had been
+hidden away, he put on half speed, swinging steadily skyward on a broad
+spiral. His purpose was to pass over the summit and have a look at the
+forests on the east side.
+
+The passenger's seat in the Wright machine is in the middle. The engine
+is at his right and the driver at his left, so that the balance is the
+same whether an extra person is carried or not. Jimmie was glad of this,
+for it placed him close to Ned. In that half light, with the earth far
+below, with the pounding of the engine and the whistling of the wind,
+the boy felt the need of close human companionship.
+
+He sat in a wooden seat with his back against the rest, holding to one
+of the uprights with both hands, and resting his tingling feet on a
+cross-bar. A guy-wire passed across in front, close to his chest, so he
+was now fastened in.
+
+He wanted to talk with Ned, to hear the sound of his voice, but the
+clamor of the engine prevented that, so he just sat still and looked
+down on the flying forest below. It seemed to him, at least, that the
+forest was moving, while he was standing still in the starlight.
+
+Up the aeroplane went, and still higher up. Jimmie saw the great divide
+below, and saw little red specks in the forests of the eastern slope
+which denoted forest fires not yet grown to maturity. After passing the
+summit Ned saw the campfire of the men Ernest had spoken of. He passed
+them, swung around a circle lower down, selected a spot where he thought
+he could land with safety, and dropped down.
+
+Jimmie declared afterwards that he felt as if he had been thrown out of
+the window of a twenty-story building--and the highest window at that.
+When the aeroplane came into the shadows of the high trees where the
+landing was being made he knew that a wind was blowing at the surface
+and feared that the machine would be carried along on the ground and
+dumped over into a caņon.
+
+The machine sank gracefully into a glade rather high up on the slope,
+and the boys alighted to stretch their legs. Ned's first move was to see
+if there was plenty of room for him to get out. What he found was an
+incline to the east, an incline ending at a great caņon, into which he
+would have been hurled had the aeroplane run fifty feet farther on the
+ground.
+
+"I think I can make it," he said, "but it is risky. It wouldn't be nice
+to take a header a thousand feet down."
+
+After the inspection of the locality Ned extinguished all the lights and
+sat down to map out his plans for the remainder of the night. There were
+the usual noises of the forest, as found at night, but no human sounds
+intruded.
+
+Ned knew that the clamor of the engine must have been heard by the men
+in the camp he had flown over, and he had no doubt that the outlaws
+would make a quick excursion to his landing place, if they could
+determine where it was. So he put out the lights and listened for some
+indication of the approach of the others.
+
+"They won't find us in a thousand years," Jimmie volunteered, as the two
+sat close together under a great tree.
+
+"I hope not," Ned replied, "for then we shall have a better chance to
+find them."
+
+"What do you want to find 'em for?" questioned the boy. "You can't pinch
+'em, 'cause you haven't got the proof, an' you couldn't if you had the
+proof, 'cause there ain't enough of us. They'd eat us up like spinach."
+
+"You are right as far as you have gone," Ned replied, "but you have not
+gone far enough. What I want now is to find out what they are doing
+here. And, also, I want to find out about that fellow from San
+Francisco. If the description is any good, he was in the city when I
+left it, and I don't see how he ever got here so soon. I came part way
+on an aeroplane, but it seems that he traveled farther and beat me out."
+
+"What's he got to do with it?" asked Jimmie. "What did you find out in
+the city? You won't have no luck if you don't tell me all about it."
+
+So, while they waited, Ned told him "all about it," while the boy sat in
+the dusk with his eyes and mouth both opened wide at the mystery of the
+thing.
+
+"I don't believe Albert Lemon ever got out here so soon," the lad said,
+when the story was told. "He couldn't."
+
+"Then who is the man from San Francisco?" asked Ned.
+
+"It can't be the dead man?" questioned Jimmie.
+
+"You saw him buried," Ned answered.
+
+"Then I give it up!" Jimmie said.
+
+The two sat there in silence a long time, then Jimmie gave Ned's arm a
+pull and pointed to a flickering light in the forest just above the
+glade where the aeroplane rested.
+
+"They think you've landed somewhere here," the boy said, "an' have set
+fire to the woods."
+
+"I think you have guessed it," Ned said. "However, the blaze won't run
+very fast up there, for the undergrowth is scanty, so we've got plenty
+of time to get out of the way."
+
+Jimmie scrambled up the slope, clinging to rocks and roots with both
+fingers and feet, and ran toward the blaze. Ned watched the little
+fellow dashing along with no little anxiety, for the outlaws might be
+there in the thickets, watching for some attempt to be made to lift the
+aeroplane.
+
+He saw Jimmie recklessly climb to the top of a great rock which jutted
+out from the side of the mountain and saw his figure outlined against
+the growing blaze on the slope above. Then the fire died down, as if for
+want of material, and the top of the rock could no longer be seen.
+
+Ned listened, but Jimmie did not return. The effort to create a general
+conflagration on the mountain side had evidently failed, for there was
+little to burn save the green boles of trees, that section having been
+swept by fire a year before.
+
+Not daring to leave the aeroplane for even an instant, Ned awaited the
+return of the boy with premonitions of trouble in his mind. Presently he
+heard a shot, then a cry, and after that a brutal laugh. The outlaws
+were nearer than he thought.
+
+There was only one thing for Ned to do, and that was to get the
+aeroplane into the sky immediately, and so once more place it beyond the
+reach of the outlaws. There was nothing he could do to aid Jimmie, he
+reflected, sadly, by remaining there.
+
+It was no task at all to start the rollers down the incline, but the
+caņon threatened if he did not get it off the ground in quick time. He
+knocked the stones out from under the wheels and sprang into his seat.
+The machine, gaining momentum, moved on sedately. It had acquired a fair
+rate of speed when he came within a few feet of the caņon.
+
+Then, after letting it get all the headway possible in that confined
+space without coming too close to the caņon, Ned pulled the lever which
+tilted the front rudder planes. Trifling as the deflection was the
+man-made bird felt its influence and rose from the slope as if endowed
+with life.
+
+It reached the edge of the descent some distance in the air, and the boy
+was congratulating himself on the success of his unaided rise when the
+big machine began to sag as if dropping to the ground, five hundred feet
+below.
+
+The west wall of the caņon ran straight down, and it seemed to Ned that
+he was following it, like an iron spike thrown off the ledge. He knew
+very well what had occurred. He had fallen into one of the down-tipping
+currents so frequent in mountain districts.
+
+The air, he knew, was sliding down the precipice just as water tumbles
+over a dam. If it turned, as it might, when it struck the lower strata
+of air, he might secure control of his machine and manage to lift it out
+of the caņon. If it did not, he would doubtless fall to the rocky floor
+of the caņon, and lie there until some chance hunter or forester came
+upon a heap of bleaching bones and the wreck of an aeroplane.
+
+But even at that swift pace downward, and at that exciting moment, Ned
+found himself puzzling over the strange sight he saw in a break in the
+wall of the caņon. It was a large opening he looked into, and strange
+figures were gathered about a cooking fire.
+
+
+
+
+CHAPTER XI.--THE LUCK OF A BOWERY BOY.
+
+
+Jimmie opened his eyes and looked about. It was a gloomy niche in a
+perpendicular wall that he looked out of. Rock to right and left and
+rear. In front a velvet summer sky, with stars winking over a vast
+stretch of broken country. There was a ledge a foot in width outside the
+entrance to the niche, but the boy could not see how long it was, or
+where it led to.
+
+His head ached and there was a drawing sensation to the skin of his
+forehead and right cheek, as if some sticky substance had congealed
+there. When he reached a hand up to see what the trouble was he found
+that his head was tied up in a cloth. There was no one in sight to ask
+questions of, so he arose to a sitting position and leaned forward.
+
+The action brought on a whirl of dizziness, and he dropped back against
+the wall for support. He knew then that he had received a hard blow on
+the head, and that he had lost considerable blood. Once before in his
+life he had felt that dizzy weakness, and that was after an artery had
+been cut in his leg and he had nearly bled to death before reaching a
+hospital.
+
+When he lay back trying to get something like a balance in his brain, he
+saw that it was near midnight. He knew that by the stars, for he had
+watched them many a hot night, lying on his back on a dray backed up
+some alley down near the East river, in New York.
+
+There were certain stars which always occupied just such a position at
+midnight in New York. He did not know their names, but he knew that at
+midnight in Montana they would not be so far advanced across the sky.
+Therefore he looked for the stars as they appeared at nine o'clock on
+the Atlantic. When he found them he knew from their location that it had
+been something over an hour since he had left Ned and the aeroplane.
+
+The three hours difference in time between New York and Montana--three
+hours in round numbers--would make the midnight stars three hours late,
+of course. Anyway, the boy was pretty certain of the time.
+
+Then his mind went back to Ned and the aeroplane, and the caņon in front
+of the landing place. He recalled the stop, and remembered leaving Ned
+to see what was doing in the way of forest fires. He remembered, too,
+getting up on a high rock to look over at the creeping flames.
+
+But strange to say he did not remember getting down again. The next
+thing on the record of his mind was that niche in the wall and the stars
+shining down out of a summer sky, the same stars he had looked at in old
+New York. Of course he had been struck the blow he had received while
+mounting the rock, otherwise he would know something of the attack.
+
+His mind did not have to travel along the records of the past very far
+to convince him that he had made a mistake in leaving Ned. Of course he
+had been "geezled" by the outlaws, as he expressed it, and of course the
+boys would delay the business they were on in order to look him
+up--which, he reluctantly admitted to himself, would be a waste of time,
+as any boy capable of doing such foolish stunts certainly was not worth
+the trouble of looking up.
+
+Presently the pain in his head became less violent and the dizziness in
+a measure passed away. Then he pushed out to the edge of the ledge and
+sat with his feet hanging over. It was a straight drop down. Below he
+could see a stream of water running along the bottom of the caņon.
+
+Out, perhaps two hundred yards from his resting place, he saw a slope
+half covered with trees. He looked down into the gulf in the hope of
+seeing the aeroplane, but it was not in sight. Ned must have taken it
+away. Or he might have been overpowered and the machine broken up.
+
+Of course the outlaws would break up the machine if they secured
+possession of it. They would not dare use it in that region, and it was
+about as handy a thing to ship away secretly as a white elephant.
+
+There were no lights in sight anywhere, save a slight glow of coals away
+down at the bottom of the caņon. That might be the remains of the
+aeroplane, or it might be a bit of forest fire which had not burned
+itself out. Very much disgusted with himself, the boy leaned farther out
+wondering if there wasn't a ledge which wound its way to the bottom of
+the caņon, or to the summit above.
+
+So intently was he studying on this proposition that he did not hear
+footsteps approaching, nor did he realize that there was any human being
+near him until he felt a hand laid lightly on his shoulder.
+
+"Be careful, young man," the voice said, "or you'll get another tumble.
+How do you feel by this time?"
+
+"Fine!" cried the boy, turning a pair of astonished eyes toward the
+south, where a bulky personage stood blocking the ledge to the extent of
+obscuration.
+
+"Well, don't take any more chances, then," said the bulky person, and
+Jimmie was forced, not ungently, back into the niche.
+
+The man entered after the boy and threw himself down on the stone floor
+of the cut in the wall of the caņon. He was short and stout, with a
+double chin and a pointed forehead which gave his face the appearance of
+being engraved on a lemon. He was quite bald, and his hair, that which
+remained, was turning gray. His eyes were steel blue, and his mouth one
+long, thin-lipped slit between fat cheeks.
+
+Jimmie did not like his looks at all, and he resented the patronizing
+voice and manner. So he leaned sullenly against the wall and waited for
+the other to open the conversation. He had not long to wait, for the man
+was busy in a moment.
+
+"How did you get that fall?" he asked.
+
+So, Jimmie thought, they were going to claim that he had a fall, and
+that they had found him, and cared for him gently, and were now ready to
+do anything in the world for his comfort. The boy decided that the
+correct course for him to pursue was to follow the lead of the other.
+
+"Guess I slipped off a rock," he said, knowing very well that he had
+been knocked off his feet so suddenly that he had instantly lost
+consciousness.
+
+"What were you doing there?" was the next question.
+
+"Why, I had been out in the aeroplane, and I got out to see if the
+forest fire I saw was going to be anything serious, and then I tumbled."
+
+"Where is the boy who was with you in the aeroplane?" asked the other.
+
+Jimmie replied that he had no idea, which was, of course, the answer
+expected of him. His questioner remained silent a moment, looking out
+over the rugged land to the east. When he spoke again it was to ask:
+
+"What are you doing in the Rocky Mountains?"
+
+Jimmie thought that was a cheeky question, and a useless one, for he had
+no doubt that the fellow knew nearly as much about his business as he
+did about his own.
+
+"We're on a vacation," he replied. "Five of us have a camp over on the
+other side of the divide. We're just playing prospectors."
+
+"Very nice vacation for you all," the other said, "but you ought to be
+more careful with your fires. You started a large conflagration
+yesterday."
+
+So the Boy Scouts were to be accused of that! Jimmie wished at that
+moment that the other boys were there. He wanted to tell this fat
+hypocrite what he thought of him and stand a fair show in the fracas
+which might follow.
+
+"I don't think we set any fires," he said. "The fires started a long way
+from our camp."
+
+"I know what I'm talking about," the other said.
+
+Jimmie did not reply. He was wondering what would be the next move of
+the fat party, and whether Ned or the boys left in camp would be out to
+look him up before the morning.
+
+"I am in charge of this district," the other went on. "I'm Captain
+Slocum of the forestry force."
+
+Jimmie did not believe it, but did not say so. He only stared at the
+other in a manner which nettled his dignity.
+
+"I have been watching you boys ever since you have been here," Captain
+Slocum went on. "I didn't know what you were up to, and so I watched."
+
+"Yes, sir," said Jimmie, quite humbly, though angry enough to fight the
+man single-handed.
+
+"It seems that you have left forest fires wherever you have camped,"
+Slocum went on, with an all-knowing air. "To-night I sent a party of
+foresters over to the camp to arrest you all."
+
+"Yes, sir," replied Jimmie again, shutting his lips hard in order to
+prevent saying a great deal more.
+
+"Do you think they will find this Ned Nestor there?" Slocum asked, then.
+
+"I don't know whether he could get his machine back to the camp," Jimmie
+replied.
+
+"Well, wouldn't he go without it?"
+
+"No, sir; I don't think he would, unless it was certain that he could
+not take it with him."
+
+"We'll find him, anyway," Slocum continued.
+
+"Where are you goin' to take us for trial?" Jimmie asked.
+
+"We'll have to consider that part of the matter later on," was the
+reply. "The first thing for us to do is to lock you up good and tight
+and stop the setting of forest fires."
+
+"Yes, sir," replied Jimmie, still humbly, but still thinking what he
+would do to this fat falsifier if he ever got a chance.
+
+"I'm glad you confess," Slocum said.
+
+"I didn't," said Jimmie.
+
+"Why, yes, you did," insisted the other. "You admitted setting the
+fires."
+
+Jimmie made no reply. Far down in the caņon he saw a glint of flame. It
+was not a forest fire. It was not even the red light of a campfire or a
+lantern. The light was white, and the boy knew it for what it was--an
+electric searchlight, such as Ned always carried on his aeroplane trips.
+
+Slocum did not seem to see the light. His eyes were fixed on the face of
+the boy he was talking with, although the features did not show very
+distinctly in the dim light of the night.
+
+"Well, to tell you the truth, we've already captured this Ned Nestor,"
+Slocum added, maliciously, Jimmie thought, "and no doubt my men have
+also captured those at the camp. Nestor broke a leg in trying to get
+away, but when he was fairly cornered he confessed everything."
+
+"Yes, sir," answered Jimmie.
+
+There was nothing else the boy could say without putting himself in the
+way of a beating. If he had expressed his opinion of this story no doubt
+he would have been given physical punishment for his frankness.
+
+"And so," Slocum smiled, "you may as well continue the confession you
+began."
+
+Jimmie recognized this as clumsy work in the third degree, but he did
+not say so. He was watching the light below. Now it disappeared behind a
+great rock or tree. Now it came out in the opening again and moved about
+in a circle.
+
+"Ned is examining his 'plane, preparatory to going back to camp," the
+boy thought. "Wonder if he's been all this time lookin' for me?"
+
+The boy paid little attention to what Slocum said after this. Most of
+the time he was looking into the sky, or anywhere rather than where his
+thoughts were fixed. He had no intention of directing the gaze of the
+alleged forester to what was going on in the caņon.
+
+Directly he saw the flashlight flutter over the white planes then become
+stationary. Ned, he knew, was getting ready to make a flight. He could
+imagine what the boy's feelings were, for he knew Ned's affection for
+him. Indeed, it was with a heavy heart that the patrol leader left the
+place without Jimmie.
+
+"And there is also a suspicion that you boys are interested in getting
+opium over the border without settling with Uncle Sam," Jimmie heard
+Slocum saying, as he watched the aeroplane move forward, lift for a
+moment, and then drop down out of sight. He knew of the precipice just
+ahead of the machine, and trembled for fear that Ned had not been able
+to lift the aeroplane, but had tumbled into the caņon with it.
+
+"Anyway," Slocum continued, "we shall place you under arrest for setting
+fire to the woods and also for smuggling."
+
+Just at that moment Jimmie was not at all interested in what Slocum was
+saying to him. He took no interest whatever in any threat made by the
+fellow. He was watching the caņon for some sign of the reappearance of
+the aeroplane.
+
+After what seemed an eternity to the lad he saw the light again, this
+time higher up than before. It was lifting slowly, turning round and
+round in a spiral, and Jimmie knew that there was no room to mount into
+the sky in a straight line. Ned's control of the machine was wonderful,
+and it lifted gradually until it was above the line of the hills on the
+other side and shot away to the west.
+
+Then Slocum saw it. Jimmie blamed himself for calling his attention to
+it by lifting his head to follow the flight across the sky.
+
+"There is another aeroplane," Slocum said.
+
+Jimmie could not restrain a laugh, which intruded oddly enough on the
+tense silence of the moment.
+
+"You don't think it is Nestor, do you?" Slocum asked.
+
+"Yes, sir," replied Jimmie, still humbly.
+
+"But he must have taken a drop down the caņon," urged Slocum.
+
+"Yes, sir," replied Jimmie, "but you said you had captured him!"
+
+Slocum eyed the boy with rage in his eyes. He knew very well that while
+he had been telling of Ned's capture and confession, Jimmie had been
+watching his chum get his aeroplane out of the caņon.
+
+"You haven't even thanked me for getting you out of the mess I found you
+in, and doctoring up your wound," he said, presently, resolved to keep
+on good terms with the boy for a short time longer, if it was possible
+to do so.
+
+"Thank you, sir!" Jimmie said, very modestly. "I think I must have
+received a good bump on the head."
+
+"Indeed you did," smiled the other.
+
+After a little further talk Slocum led the boy away to a cavern in the
+wall of the caņon which seemed to the weary lad to have no end. He saw
+several people lounging about as he passed through a large chamber, but
+paid little attention to them.
+
+At last Slocum halted in a little alcove opening from a second chamber,
+in which were assembled at least a score of Chinamen.
+
+"These people won't harm you," he said to the boy, swinging his arm
+about to include the group. "Uncle Sam is trying them out in the forest
+service, I don't think much of the idea myself, but I'm not the boss."
+
+Then Slocum went away and Jimmie lay down and watched the Chinamen.
+Listening, he heard one of them speaking in English, then in Chinese. He
+knew that he had heard that peculiar voice and dialect before and
+devoted his whole attention to the fellow.
+
+"Well," he muttered, in a moment, with a grin, "I'm havin' the luck of a
+Bowery boy in this deal, an' that is the greatest luck in the world."
+
+Then he fell to wondering what Chang Chee, the keeper of one of the
+worst Chinese restaurants on Doyers street was doing there, in the heart
+of the Rocky Mountains, mixed up with alleged foresters.
+
+"Just wait until I see Ned!" the boy mused. "I'll put him next to
+somethin'. He'll be glad he brought me with him!"
+
+Then the boy's thoughts went back to the camp in the Valley of the Wild
+Beasts, as he called it. Slocum might have told the truth about the
+attack on the boys, and they might be in trouble at that moment. He
+wondered, too, if, in case they were taken prisoners, they would be
+brought to the cavern.
+
+"Anyhow," the lad mused, "they never intend to let me get out of this.
+If they did, they wouldn't have permitted me a sight of the Chinks.
+Unless I sneak away, there'll be an accident some day, an' then there'll
+be no more Jimmie McGraw!"
+
+The boy was tired and weak, so that even such serious thoughts as these
+could not keep him awake. Wondering what conditions Ned had found at the
+camp, after soaring out of the caņon, he dropped his head against the
+stone wall of the alcove and was soon in a deep sleep. The fumes of
+opium with which the cavern was filled might in a measure have
+contributed to this, but, anyway, nature was exhausted, and the boy's
+slumber was heavy and dreamless.
+
+
+
+
+CHAPTER XII.--A MEMBER OF THE OWL PATROL.
+
+
+When Jimmie awoke the fire which had burned in the cavern had gone out,
+and those who remained in the chamber seemed to be fast asleep. He
+tumbled out of his alcove, still feeling weak and dizzy, and moved
+toward a hanging rug which closed the entrance to the place.
+
+He drew one side of the rug back and saw the white light of day. The sun
+seemed to be high up in the sky, for the ledge at the front of the
+cavern showed a streak of gold. Two Chinamen sat at the entrance to the
+outer cave, and when he advanced toward them they waved him back.
+Instead of retreating he stood regarding them with a puzzled look on his
+face.
+
+One was Chang Chee, the keeper of the disreputable Chinese dive on
+Doyers street, whom Jimmie had noticed the night before, and the other
+was a much younger man--a boy, in fact. When Chang ordered Jimmie back
+the youngster turned toward him a face showing both curiosity and
+interest.
+
+"What's doin' here?" Jimmie demanded, in a moment.
+
+He thought best not to show that he recognized Chang, for he knew that
+the identification of the Chinaman would only add to his peril, if that
+were possible. It was certain that Chang would never permit the
+information that he had been seen there to get out to the government
+officers.
+
+Jimmie's idea at that time was that he had blundered on a gang of opium
+smugglers, although he could not understand why so many Chinamen were,
+apparently, engaged in the illegal traffic.
+
+Chang finally turned his face away, with a frown, and Jimmie advanced a
+step toward the boy, who threw himself carelessly down on his back and
+extended his right arm straight up from the shoulder. Jimmie's eyes
+opened wider, and his breath almost stopped, when he saw the thumb and
+little finger thrown diagonally across the palm of the hand, the tip of
+the thumb covering the nail of the little finger, the three remaining
+fingers pointing upward.
+
+In the excitement of the moment, in the amazement caused by his
+recognition of the Boy Scout challenge, Jimmie lost all caution.
+
+"Say!" he began, but Chang turned a repulsive face and ordered him into
+the rear chamber.
+
+The boy, thankful for the interruption, moved back a few paces,
+believing that the Chinese boy who had given him the sign would
+communicate with him as soon as opportunity offered.
+
+This was the greatest puzzle the lad had ever been called upon to solve.
+Some of the questions he asked himself were:
+
+"How did that Chinese boy become a Boy Scout?"
+
+"Is there a Chinese patrol?"
+
+"Was he permitted to become a member of an American patrol?"
+
+"Why is he mixed up with that disreputable old Chink?"
+
+"Will he help me out of this hole, or will he ignore me?"
+
+Of course there was not one of the questions the boy could answer, so he
+went back to his alcove and sat down, half believing that he had
+imagined the challenge.
+
+As the day wore on the men who had been asleep in the inner chamber
+arose, staggeringly, as if still under the stupefying influence of
+opium, and made their trembling way outside. When they had all
+disappeared Chang pushed the rug aside so as to bring more light and air
+into the place and came and stood looking down on the boy.
+
+Jimmie did not look up. He saw the shrunken figure up as far as the
+knees only. He was resolved not to open any conversation with the Chink.
+If he wanted to talk, Jimmie thought, let him choose his own subject and
+introduce it in his own way.
+
+The yellow face of the Chinaman seemed to take on a more mask-like
+expression--or want of expression, rather--as the silence continued.
+When he spoke it was with a snarl which boded no good to the boy.
+
+"Hungly?" he demanded.
+
+"Hungry?" repeated Jimmie. "You know it! If you've got any rat
+sandwiches or puppy potpies, just introduce me!"
+
+"Flesh!" growled Chang.
+
+"Flesh?" repeated Jimmie. "Oh, yes, you mean fresh? Well, you'd be just
+as fresh as I am if you were as hungry."
+
+"Cheek!" cried Chang. "Kid allels have cheek--an' tummy!"
+
+"Sure," said Jimmie. "Go on an' get me a porterhouse steak with French
+potatoes. I could eat a car of raw onions."
+
+Chang turned away and walked out to the ledge, where the Chinese boy
+stood, looking out into the sunshine. It was a glorious morning, with
+the air clear and just a little sharp, owing to the altitude. Here and
+there little swirls of smoke showed that fires were burning in the
+forest, though none seemed to be close to the range.
+
+Reaching the boy's side Chang addressed a few words to him in Chinese
+and left the cave, turning back, after a few paces, to observe the boy,
+now standing with a long, keen-bladed clasp-knife in his hand. As Chang
+looked the boy ran his finger over the edge of the blade, as if to make
+sure that it was suitable for some purpose he had in view.
+
+With an exclamation of rage Chang charged back at him and snatched the
+knife from his hand.
+
+"You fool!" he cried.
+
+"You let me alone!" shouted the other. "I tell you, I'm going to kill
+him!"
+
+Jimmie heard the words and rose unsteadily to his feet. He recognized
+the voice as that of the boy who had given him the Boy Scout challenge.
+At least it was not that of Chang, and there were only two figures
+outlined against the sky when he looked out beyond the rug, still pushed
+aside.
+
+"Fool! Fool! Fool!"
+
+Chang gritted out the words as he took the Chinese boy by the back of
+the neck and hustled him into the cave. Then he spoke for a minute in
+Chinese and turned away again. Jimmie stepped back into his alcove and
+felt around for a stone, or anything in the shape of a weapon, as the
+boy advanced toward him.
+
+"What does the badge say?"
+
+Jimmie opened his eyes wider than ever, if possible, and stood facing
+the boy, half hiding the stone he had found.
+
+"Be prepared," he replied.
+
+"Then drop that rock!"
+
+Jimmie dropped it and stepped forward.
+
+"Liu, Owl patrol, San Francisco," the Chinese boy said.
+
+"McGraw, Wolf patrol, New York," replied Jimmie.
+
+"You don't look very comfortable in here," Liu said.
+
+"Nixy," replied Jimmie, wondering if the boy really was preparing to
+carry out the threat he had made to Chang.
+
+"You heard what I just said to Chang?" Liu asked.
+
+Jimmie nodded his bandaged head.
+
+"Bluff!" said Liu. "He's watching now to see that I don't make an
+attempt on your life. Had to do it!"
+
+"I see," Jimmie replied, wondering if it wasn't pretty near time to wake
+up.
+
+"Why don't he want me killed?" Jimmie asked in a moment.
+
+"He thinks you have information he needs," was the answer. "Are you
+hungry?"
+
+"That's what Chang asked," Jimmie said, "but he didn't bring me any
+grub."
+
+"He told me to," grinned Liu, "and I told him that I'd kill you if I got
+near enough to do so. He'll hang around until he sees me bring you
+something to eat."
+
+"You ain't so very slow yourself," grinned Jimmie. "Where did you learn
+to speak United States so well?"
+
+"Born in Frisco," was the reply. "The Boy Scouts take me out on their
+hunting trips to do the cooking. That's why I'm here now. I know the
+mountains, and Chang hired me to go along with him."
+
+"An' they took you into the patrol, did they?" asked Jimmie.
+
+"Sure they did," was the reply. "Why not? I'm an American citizen, or
+will be in four years."
+
+"Have they captured any of the others?" asked Jimmie.
+
+The Chinese boy shook his head.
+
+"Have they heard from the men they sent out to capture them?" was the
+next question.
+
+Another shake of the head, then Liu drew closer and whispered.
+
+"Do you see Chang poking his head around that rock in the opening? He's
+watching to see that I don't knife you!"
+
+Jimmie saw the parchment-like face of the old reprobate peering around
+the rock and wanted to heave a stone at it, but knew that this would not
+be good policy. Instead he threw it at Liu, and missed, of course.
+
+"You seem to be wide awake yourself," Liu said.
+
+"Why don't you go and get me some grub?" demanded Jimmie. "I'm near
+starved to death."
+
+"All right!" said Liu, and turned away.
+
+Jimmie was now in a deeper puzzle than before. He had no means of
+knowing whether Liu was telling him the truth. He might be trying to get
+into his confidence in order to gain the information sought, whatever it
+was.
+
+However, in a short time Liu returned with a generous supply of food,
+fried fish, fresh biscuit--the boy wondered how Liu had managed to bake
+them there--coffee, and plenty of tinned goods.
+
+"What's this bunch doin' here?" the boy asked, as he made heavy inroads
+on the fresh fish, coffee and biscuits.
+
+"I don't know," was the hesitating reply.
+
+"I know," Jimmie went on. "They're smuggling opium an' setting fire to
+the woods. They'll all get pinched!"
+
+"I hope so," was the reply.
+
+"It sounds odd to hear a Chinese boy talk straight United States,"
+Jimmie said, after a short silence.
+
+Liu made no reply for a moment. He was watching the ledge outside the
+entrance to the cave. The occasional rattle of pebbles told him that
+some one was standing there, probably just out of sight.
+
+"What is Chang doin' here?" Jimmie asked, presently.
+
+"He's in some scheme with the foresters," was the reply.
+
+"They ain't no foresters!" Jimmie said. "They're timber thieves an'
+smugglers, an' firebugs, an' murderers!"
+
+Liu shuddered but remained silent. After listening a second he went to
+the entrance and looked out. There was no one in sight at first, then a
+roughly dressed fellow came around the angle of the cliff to the north
+and approached him. The fellow was rather short for a man of his width
+of shoulder, and his step was remarkably light and quick for one of his
+apparent weight.
+
+His face was sun and wind-tanned, with plenty of mountain soil on top of
+that. A cartridge-belt encircled the loose jacket he wore and a revolver
+handle protruded from the pistol pocket of his trousers.
+
+"What's the word?" he asked, gruffly, as he came up to Liu.
+
+"Go on in," replied Liu.
+
+Jimmie saw evidences of treachery in the hostile attitude of the
+newcomer and retreated farther into the cavern.
+
+Then he saw Liu doubling up with laughter and stopped. It didn't look
+very amusing to him, especially as the stranger was advancing toward him
+with swift strides. Then something remotely familiar in the set of the
+shoulders, the carriage of the head, attracted his closer attention to
+the figure and he moved forward a step.
+
+"You're a nice little boy to get into a trap like this!"
+
+There was no mistaking that voice. Just how Ned Nestor had secured that
+disguise and found his way to that spot Jimmie did not stop to think. He
+knew that it was his chum, and that was enough. While the two boys
+clasped hands Liu stood regarding them smilingly, at the same time
+watching the entrance.
+
+"How did you ever find this hole?" Jimmie asked, his wonder at the thing
+which had happened mastering all else.
+
+"I saw this cave when my machine dropped into a hole in the air in the
+caņon," was the reply. "The shelf where we landed is just above this
+cavern. There was a fire in the outer room, and numerous Chinamen were
+moving about."
+
+"They're opium smugglers," Jimmie said.
+
+"Man smugglers!" laughed Ned.
+
+"Do you mean that they bring Chinks over the border here, an' so run
+them down into civilization whenever they get a chance?" demanded
+Jimmie.
+
+"That is just it," Ned answered. "We seem to have come upon a lot of the
+articles to be smuggled," he added.
+
+"How did you come across Liu?" Jimmie asked.
+
+"Oh, I met him while I was prowling about not far from the cave, at
+daylight," was the reply. "He helped me get this disguise."
+
+Liu was still watching at the mouth of the cavern, so the boys talked
+freely, with little fear of being disturbed. Ned told of his return to
+the camp, and of the all-night hunt for the missing boy. It took Ned and
+Frank a long time to find the opening the former had seen in his swift
+drop down the caņon, but about daylight it was located.
+
+They had, however, found many Chinamen loitering about, and Frank had
+gone back to camp to reassure the others, while Ned remained on the
+eastern side on the chance of getting into communication with Jimmie.
+While loitering about Liu had come up the slope.
+
+It was quite a long story, that of his getting a perfect understanding
+with Liu, and Ned cut it as short as possible, merely saying that Liu
+had recognized his name, having heard his associates mention it
+frequently. Then the Chinese boy had procured the disguise and Ned had
+stuffed out the shoulders of the coat to give it a better fit.
+
+"I was observed by a half a dozen men, some Americans, some Chinamen,
+while getting in here," Ned said, then, "but the disguise misled them.
+Now, the question is this: How are we going to get out?"
+
+"We'll have to fight our way out?" asked Jimmie.
+
+"It won't answer," Ned replied. "They are too many for us."
+
+Liu now came into the second cave and held up his hand for silence.
+
+"You'll have to hide in the back chamber," he said. "Chang is coming
+in."
+
+"I thought this was the back chamber," Jimmie said.
+
+"I suspect," Liu said, "that there's a chain of caves running through
+the divide. Come on!"
+
+Liu passed back to the west, removed a great box which stood against the
+rear wall, and disclosed an opening through which the patrol leader
+crawled. When the box was replaced Ned stopped and listened. What he
+heard was the click of a typewriter.
+
+
+
+
+CHAPTER XIII.--OFF ON A DESPERATE MISSION.
+
+
+What business calling for the use of a typewriter was being transacted
+under the main divide of the Rocky Mountains?
+
+Ned stood perfectly still in the darkness and listened. He could hear
+the click of the keys and nothing else. At length he moved stealthily
+forward over an even surface, feeling his way in order that he might not
+trip over some unseen obstruction and raise a racket in a tumble.
+
+Presently he came to a rug hanging at the end of the chamber in which he
+was. From the other side of the rug came a faint light. The noise of the
+keys was more distinct here, and the boy knew that he had at least
+located the operator.
+
+While he stood listening and undecided as to what course to pursue, the
+noise of the machine ceased and the operator--a young, well-dressed
+American--came toward him carrying a lighted candle in his hand. Ned
+crouched down in an angle of the wall and waited for him to pass.
+
+The boy was not quite so anxious now to leave the strange rendezvous in
+which he found himself. Some mischief greater than smuggling opium and
+Chinamen over the border might be carried on there. His work seemed to
+be growing on his hands!
+
+He had been sent to that district to investigate the cause of the
+frequent forest fires, and given an aeroplane in order that he might fly
+over the forests in making his observations. It seemed to him now, as he
+lay on his side against a wall of rock, waiting for the typist to pass
+with his light, that he was spending more time under the ground than in
+the air!
+
+The main range of the Rocky Mountains in the northern part of Montana is
+noted for its rugged and irregular formation. It is declared by some
+that the home of the original cave dwellers was here. Many of the great
+caņons are known to be honeycombed with openings almost large enough to
+hide a small city in.
+
+The typist moved straight ahead and his light disappeared from view.
+Then Ned advanced beyond the rug, which appeared to be of fine material,
+and flashed on his light. There was a table in the room, a couple of
+chairs, a row of pigeon-holes attached to the wall.
+
+On the table was a typewriter, in the pigeon-holes were folded papers,
+neatly ticketed and enclosed in rubber bands. Aside from the underground
+smell the place was tolerably comfortable. The air was damp and chilly,
+but Ned was well clothed and did not mind that.
+
+As has been said, the boy was now in no haste to leave the place. He
+believed that the mystery he had been sent out to solve would be solved
+there. For an hour or more he searched over the place, opening the
+folded papers and making a close examination of the typewriter and the
+stock of unused paper in the drawer of the table.
+
+At length, his examination completed, he passed back into the chamber
+behind the rug and listened at the opening through which he had entered.
+A sound of the steady beat of blows reached his ears at first, then a
+low whistle. That was Jimmie, he knew. The lad had a habit of whistling
+softly to himself, usually without time or tune.
+
+Waiting for a lull in the blows, he rapped softly on the box which
+backed up against the opening. Instantly the whistling ceased, and
+Jimmie's voice was heard.
+
+"Come on out," the boy said. "I've been kicking my heels against this
+box for an hour, waitin' for you to signal back."
+
+"Be sure there is no one watching," Ned cautioned.
+
+He heard Jimmie walking away, then heard him coming back. In a moment
+the box was drawn away from the opening.
+
+"You've been in there long enough to dig through to China," Jimmie said,
+as Ned stood by his side. "What did you find in there?"
+
+"A double keyboard typewriter," grinned Ned.
+
+"Quit your kiddin'," answered Jimmie. "You'll be claimin' next that you
+found a brass band in there."
+
+Ned did not stop to explain to the boy all that he had discovered in the
+inner chamber. His work there seemed to be finished now, and he was
+anxious to get back to camp. There was no knowing what had been going on
+there during his absence.
+
+"Where is Liu?" he asked.
+
+"Watchin' outside," was the reply. "He's my guard. Goin' to shoot me if
+I try to get away."
+
+"And the others?" asked Ned.
+
+"Don't know," replied Jimmie. "They herded a lot of Chinks an' went off
+down the valley."
+
+Liu now appeared in the entrance, bowed gravely to the boys, and stepped
+out on the ledge, with a Boy Scout challenge in the wave of his hand.
+
+"He's all right!" Jimmie said. "You ought to see the breakfast he got up
+for me. That feller can cook--an' then some!"
+
+"Call him," Ned suggested, "and we'll see if it is safe for me to go
+out."
+
+"For you to go out!" repeated Jimmie. "For us to go out."
+
+"I think you'd better remain here," Ned replied.
+
+Jimmie looked at his chum in amazement. The light back there was not
+good, but Ned saw several questions in the boy's eyes.
+
+"Liu can protect you, can't he?" Ned asked.
+
+"That's what I don't know," was the reply. "He will do his best, of
+course, but his best might not be good enough."
+
+Ned was thinking fast. If he permitted the boy to leave, the fact of his
+escape would be likely to scatter the outlaws--and he very much wished
+to keep them together for a short time.
+
+"I think," he said, "that we have found the men we want--with the goods.
+If you leave now they will make a quick getaway. You see that, don't
+you?"
+
+"Of course," was the reply. "An' I see, too, that if I remain I'm the
+one that's likely to make a quick getaway--to a country no one comes
+back from."
+
+"There may be some other way," Ned said, thoughtfully. "Give me a chance
+to think it over."
+
+"Oh, I'll stay, all right," Jimmie went on, "if it will do any good. I
+guess they won't eat me alive."
+
+As he spoke the boy put his hand to his eyes and gave them a long rub.
+
+"There's smoke in here," he said. "Don't you smell it?"
+
+"I was thinking of that," Ned replied, anxiously. "There may be a fire
+in the caņon."
+
+Regardless of consequences, Jimmie rushed to the ledge and looked out.
+The sun was no longer in sight, for a mist of smoke hung over the caņon
+and over the slope to the east.
+
+"There's goin' to be the biggest blaze ever!" Jimmie cried.
+
+Liu came to the side of the boys and pointed to the south.
+
+"The fire came through a gully over there," he said. "I was watching it
+from here. It was not put out yesterday, and worked its way over the
+divide. When it gets to going strong here no one can live in this
+cavern. I'm going to get out."
+
+"That's the idea!" Jimmie cried.
+
+The caņon was a veritable fire trap. For years the boughs and the turp
+of the trees had been dropping down. Ned knew that the blaze would mount
+to the cavern and be drawn into it. The atmosphere of the place
+indicated openings at the rear which would serve as chimneys.
+
+"Oh, the devils!" Jimmie cried. "To set a fire like that!"
+
+"They didn't set it, I tell you," insisted Liu, speaking as if in the
+defense of his employers.
+
+"Who did, then?" demanded Jimmie, half angrily.
+
+"It came through from the other side, just as I told you," replied Liu,
+with the utmost good nature. "There'll be a pass through the range some
+day where the fire found its way through."
+
+"But they set the fire on the other side," Jimmie urged. "They set it
+for the purpose of burning our aeroplane an' driving us out of the
+district. When we go out of the district they'll go with us, wearin'
+steel bracelets!" he added.
+
+"I rather think," Liu said, "that they set the fires over there to draw
+the foresters, away from this section, and so protect their business.
+That is what they have been doing right along."
+
+"Yes," Ned said, "there has been a forest fire for every cargo of opium,
+for every gang of Chinamen, that has been brought in over the border."
+
+"So that is the real trouble?" asked Jimmie. "How do you know so much
+about it?"
+
+Ned smiled and pointed to the slope to the east, where columns of fire
+were cutting their way through the timber.
+
+"It strikes me," he said, "that now is a pretty good time for us to get
+out of this. The outlaws won't come back so long as this danger exists,
+and we shall not be missed for a long time--or rather, Liu and Jimmie
+will not be missed."
+
+"They'll think we ran out to escape the heat and lost our lives in the
+fire," Liu said.
+
+Ned stood hesitatingly at the mouth of the cavern while Liu gathered a
+few articles he wanted to take with him.
+
+"If I thought the fire would reach the cave when the big trees in the
+caņon get to going," he mused, "I'd go back and get the papers--or more
+of them."
+
+"It surely will get into the cave," Liu said. "You see, the summit
+scoops down here quite a lot, and the timber line is almost to the top.
+The gulch below is quite high up on this elevation, still it is not so
+very high as compared with some of the summits to the north and south.
+So, you see, the timber line here is capable of getting up a good deal
+of a blaze, especially where the caņons are full of trees. The fire will
+come up here, all right."
+
+Ned darted away, was gone a minute or so, and returned with hands full
+of folded papers.
+
+"What you got?" demanded Jimmie.
+
+Ned laughed but made no satisfactory reply. After stowing the papers
+away in the numerous pockets of his borrowed suit, he led the way down
+the ledge, away from the cave he had first seen in his fall down the
+caņon, and which had proved so profitable to his search.
+
+The air was now filled with smoke. The caņon below was not yet in full
+flame, but a column of destruction was creeping upon it from the south.
+It seemed to Ned that there were numerous small fires, though how this
+could be true he could not understand.
+
+The boys made their way along the ledge without coming upon any of the
+men who had occupied the cavern. It was evident that the few left after
+the departure of the men with the Chinamen had fled before the clouds of
+smoke. The ledge wound up on the plateau from which Ned had dropped the
+night before, and here they paused to decide on some course of action.
+
+The light breeze was from the west, so the fires below were in a measure
+protected from it by the bulk of the summit, but Ned knew that the heat
+would in time bring the air into the burning spaces with a rush, merging
+the little blazes into one gigantic one which might repeat the disasters
+of August, 1910.
+
+Now and then, from far to the east, there came a signal in the shape of
+a gunshot. The faithful foresters were at work there, trying to head off
+the advancing flames before they passed beyond control. The place to
+combat a forest fire, of course, is ahead of it, and not where the red
+line is running through the sputtering timber.
+
+"If I could get the aeroplane," Ned said, as he looked over the country
+from the plateau, "I might get to the fighting line and do some good."
+
+"Where is it?" asked Liu.
+
+"At the camp."
+
+"The others won't dare bring it out, of course?" asked Liu.
+
+"Doubtful," Ned replied. "Frank has always taken a great interest in the
+machine, and was studying its mechanism when I left, but I don't think
+he will attempt to operate it. He ought not to, anyway."
+
+"If the men who left here to pinch the boys," Jimmie said, "showed up at
+the camp, an' Frank got a chance to mount the aeroplane, you bet your
+life he's shootin' through the air with it this minute, or hidin' in
+some valley."
+
+"But there were three of them," Ned urged, "and all couldn't ride."
+
+"They'd try!" gritted Jimmie, "unless Pat got cold feet an' run away."
+
+Ned glanced up at the sky, now very thick with smoke, as the boy spoke.
+He looked with indifference at first, then with interest, then with
+anxiety. There was a shape moving up there, coming slowly toward the
+plateau.
+
+"There they are!" shouted Jimmie, whose attention had been attracted to
+the sky by Ned's fixed gaze. "Frank's runnin' the machine. I'll bet
+dollars to apples that he'll dump her into the caņon when he tries to
+land here."
+
+The aeroplane, indeed, looked as if there were an uncertain hand at the
+helm. She wavered, tipped in the air currents, dipped wickedly, circled
+staggeringly, but finally swooped down on the plateau and, more by good
+luck than good handling, settled down within a dozen feet of the lip of
+the caņon. Frank and Jack were aboard. Pat, they said, had taken to his
+heels at the first suggestion of his joining the others in the ride.
+
+Ned examined the machine carefully and found it in excellent shape,
+although the gasoline was getting low.
+
+"Better go an' get some," Jimmie suggested.
+
+Ned looked toward the line of smoke off to the east.
+
+"We can reach the firing line with what we have," he said, in a moment,
+"and that may be sufficient for the present."
+
+"What you goin' to do?" demanded the boy.
+
+"Going to see if I can't help fight this fire," was the reply.
+
+"From here?" laughed Jack.
+
+Ned indicated a distant line of hills where the forest still stood green
+on the slopes.
+
+"We'll fight the fire from there," he said. "We can see the location
+well enough now, but the smoke will soon shut it out from here."
+
+"What can we do when we get there?" asked Jack. "We are safe enough
+here. The smoke and heat may scorch us a little, but we'll live through
+it, and that is more than we can say about the safety of the place you
+point out."
+
+"Pat will be making his way here," Ned said, "and you may as well remain
+here and meet him. I'll take Frank and go over to the place where the
+foresters are fighting the blaze."
+
+Jimmie was on his feet in an instant.
+
+"Me for the ride with you!" he shouted.
+
+"Some one may have to run the machine back," Ned said. "You can't do
+that, my little man, and Frank can, so Frank goes."
+
+"I don't see what you can do over there that the foresters can't do,"
+Liu said.
+
+"There is no knowing how useful the aeroplane may be," Ned said.
+
+Then the machine was rolled back as far up the plateau as possible, the
+boys took their seats, and then they were lost in the dense clouds of
+smoke in the sky.
+
+[Illustration: ILLUSTRATION No. 4]

+
+
+
+CHAPTER XIV.--THE BATTLE IN THE AIR.
+
+
+The smoke was driving fiercely through the green trees on the slope, and
+the line of fire was not far in the rear. Every moment the wind gained
+force, every minute the flames leaped higher and faster.
+
+The foresters felling trees and clearing a space at an advantageous
+point some distance in advance of the flames were working blindly,
+mechanically. The heat was intense, the smoke suffocating, irritating,
+blinding. The shirts of the workers were open at the throat, their coats
+had long ago been lost as they had been beaten back from one stand to
+another.
+
+Now and then a worker dropped senseless in his tracks, his lips cracked
+with the heat, his face blistered, his tongue lolling from his smarting
+mouth like that of an overworked horse. Then the men who were able to
+move and understand would carry him back to a spot of supposed safety
+and return to re-engage in the almost hopeless fight, the battle which
+the flames were winning in every charge and sally.
+
+The aeroplane, after a narrow escape from destruction, landed on a
+little rise of ground back of the working line when the wind lulled for
+an instant, and hope shone in the faces of the astonished men who
+gathered about to greet the unexpected arrivals.
+
+"We can master it," Green, the leader, said, after many questions had
+been asked and answered, "if we can be supplied with water. We wasted
+our supply wetting our clothes a long time ago, and are suffering."
+
+"Get us water," shouted another, "and we'll win yet."
+
+"There's a spring three miles away," Green went on, speaking in Ned's
+ear, for the roaring of the flames drowned all ordinary conversation.
+"If you can take our water bottles there and fill them we can beat this
+blaze. If you can't we've got to retreat and let the whole district burn
+over."
+
+"I have very little gasoline," Ned replied, "but I'll try."
+
+"We sent two men out not long ago," Green continued, thrusting his
+scorched face close to the boy's. "We sent them out with water bags, but
+there are no trails, and It will take them hours to make the spring and
+return. With your aeroplane you ought to do it within half an hour."
+
+"Fire fighters marooned without a supply of water, or a trail cut to a
+spring!" shouted Frank, scornfully. "Great head some one in authority
+has!"
+
+"There are no trails, no telephones, no horses!" cried Green. "It looks
+as if the government sent us here to die. Hurry up with that water."
+
+"If the gasoline holds out," Ned said, loading a dozen water bags on the
+machine, "I'll be back here in less than half an hour, bar accidents."
+
+"There is plenty of gasoline back there in the shanty," cried Green. "We
+have been using it lately in starting back fires, but the wind is now
+too strong for that. Get a move on, and take all you want."
+
+In a short space of time, but not without great risk, the tanks of the
+aeroplane were filled, and then Ned took in the general situation in the
+sky. The wind was blowing in puffs, but it was certain that a miniature
+tornado was at hand. He thought he could reach the spring, which had
+been described as lying to the southeast, but was not certain that he
+could make his way back.
+
+He believed, however, that by flying either very low or very high up, so
+as to get all the protection possible from the mountain, or escape the
+sweep of wind just above the fire, he might be able to bring in one load
+of water before the worst of the wind storm came. He knew that it was an
+almost unheard of thing to even try to navigate the air in such a gale,
+but human lives were at stake, and he decided to try.
+
+"You'll have to help me up against this wind," Ned said to Green. "If I
+start with the air current I'll be carried too far to the east before my
+power begins to become effective. If I can hold my own against the wind
+until I get above the smoke I think I can win the game."
+
+It was a desperate expedient, but it appeared to be the only possible
+one. If the men had water they might succeed in stopping the fire and
+saving millions of dollars worth of timber. If the fire gained the upper
+hand they might lose their lives. The men cleared and smoothed a path
+for the run of the wheels, by great exertion sent the machine along at
+good speed, and then stood and watched it with anxiety depicted in their
+faces.
+
+The great white bird quivered in the face of the wind, but the motors
+were true to their duty and the rudder held. To turn about in the face
+of that rush would be impossible, so Ned worked his levers guardedly and
+kept the wings as level as he could. Now and then a swirl of heated air
+would shake the hopes of those watching below, but in the end the
+aeroplane drifted slowly ahead, up, higher up, and was lost in the
+smoke.
+
+"The lad is worth his weight in gold!" shouted Green. "He'll do it! I
+know he'll do it!"
+
+"Powerful motor," one of the foresters said. "When we saw the machine
+last she was actually holding her own against the wind."
+
+This was, indeed, the fact, but the wind was not as strong in the higher
+levels as at the upper limit of the heat from the fires. A great fire
+usually brings a great wind, as those who witnessed the burning of
+Chicago and San Francisco well know. The hot air rises, forming a
+partial vacuum, and the colder air rushes in.
+
+Ned and Frank gained the spring, filled their water bags and started
+back. It was no easy task to land near the spring in that whirl of wind,
+nor yet an easy task to get the aeroplane into the air again, but the
+feats were accomplished. Often after that exciting day the boys declared
+that they had no idea how they ever did it.
+
+"We were excited," Frank would say, "and took chances, everything worked
+in our favor, and we loaded the water. We knew that lives were at stake,
+and it seemed that we had the strength of a score of men, and the cool
+heads of men far beyond all excitement. I never saw anything like the
+way Ned handled the levers. The wings and the rudders seemed to me to
+work on a brain suggestion rather than on a movement of the levers."
+
+But the most difficult part of the journey still remained to be
+accomplished after the water had been secured. The 'plane was much
+heavier and did not respond so readily to the hand of the driver, and
+the return course was quartering against the wind. Ned, however, did not
+attempt to move directly toward the destination he sought.
+
+Instead he sailed off to the south, working west as much as possible. He
+tacked as a yacht tacks in the wind and came near upsetting several
+times. He found it impossible to sail low on account of the eddies and
+currents created by the heat, and so lifted the machine far up into the
+air. It was better sailing there, and he managed to get as far west as
+he thought necessary.
+
+But he could not see the landing place. Below was an ocean of smoke, the
+waves heaving in the touch of the wind, the edges now and then tipped
+with flame. Above the sun smiled at him, and the birds flew excitedly
+about, peering down at the threatening roll of clouds.
+
+"I'm afraid," Frank said, grasping an upright and clinging to the water
+bags.
+
+"I never was so frightened in my life," Ned called back, lifting his
+voice so that it might be heard above the snapping of the motors.
+
+"I didn't finish," Frank called back, his heart thumping loudly. "I
+wanted to say that I was afraid we'd sweep past the workers when we
+descended into the smoke and the swifter breeze near the earth."
+
+"I said just what I wanted to say," Ned answered. "I never was half so
+scared in all my life."
+
+Yet his hand on the lever was steady, his brain was as cool as if he had
+been sitting in the Wolf Patrol club room in New York. He knew that the
+dip of a wing a foot lower than he intended might send them both into
+the blazing forest below. He was afraid, but not with a shrinking,
+physical fear, but afraid because he understood the peril he was
+in--because he knew that upon his efforts depended the lives of the
+heroes in the heated hell below.
+
+"We've got to go into that mess of smoke, I suppose?" shouted Frank.
+
+"There is no other way," Ned called back. "We've got to dip down low
+enough to see the line of fire and take our chances on landing where the
+fighters are. You understand that they are farther to the east than when
+we left them?"
+
+"Of course they have been driven back," Frank said. "I never thought of
+that. We may not be able to find them at all."
+
+Ned shut his teeth and settled his jaw.
+
+"We've got to find them," he said.
+
+A long, sullen roaring, like the beating of waves on a beach in a storm,
+now reached the boys' ears, even shutting out the chattering of the
+motors. It came from the west, and passed along, as it seemed, below the
+level held by the aeroplane, now high up in the air.
+
+"If we don't get down there pretty soon," Ned said, shouting, "we will
+be too late. That wind will join the different fires and make one
+roaring mass of the whole northwest. I wish I knew just how far the
+foresters have been driven back."
+
+"Do you know where to look for them, north or south?" asked Frank.
+
+"There is a peak to the west and one to the east," was the reply. "They
+are on a line with the two. But the trouble is that we can't see the
+peaks after we drop down into the smoke."
+
+"There appears to be a little lull in the wind now," Frank said,
+shutting his lips tight, as a man does when about to make a sudden
+plunge into unknown waters.
+
+The remark was suggestive. Ned knew by it that his chum had braced
+himself for the dash.
+
+"Here we go, then," Ned replied. "Remember that we'll go about eighty
+miles an hour when I turn the motor on full head, and that we can't be
+more than five miles from the spot where we left them, so keep your eyes
+out."
+
+The aeroplane dipped gracefully as Ned touched the lever. In a minute
+the boys were surrounded by smoke. It was hot smoke, too, and made
+breathing difficult. Their eyes smarted until their faces were wet with
+nature's protest against such irritation of the organs of sight. The
+chuck-chuck, snap-snap of the motors was in their ears, the seats they
+occupied--frail rests between life and death--shivered under the
+pulsations of the machine.
+
+Now and then the aeroplane dipped frightfully, but the wings and the
+rudders brought it back again.
+
+"Can you see the earth yet?" asked Frank, In an awed tone, which sounded
+like a whisper in that clatter.
+
+"We seem to be over the fire," Ned returned.
+
+And that was all. There was no need of conversation. In all their lives
+they would never be so near to a frightful death as they were then.
+
+First they caught sight of a rocky ridge. Ned knew where that was, and
+realized that he was still in the direct line of the workers. Beyond
+this ridge, he knew, was a valley, so he must drop down. The workers
+were on a level beyond the valley, a great plain of fir and pine between
+gigantic ranges of the Rocky Mountains.
+
+The aeroplane trembled as she dropped, swiftly, apparently straight
+down. Frank grasped his upright and prepared to spring out of the
+wreckage when it fell, if there was anything to fall from after the
+trees had had their way with the frail machine.
+
+The smoke was blinding. Nothing could be seen but smoke for a time. Then
+the dark gray clouds turned red, and Ned knew that he was nearing the
+advance line of the fire, and that it was mounting to the very tops of
+the giant trees on the plain--or elevated plateau, rather, for, though
+comparatively smooth of surface and heavily timbered, it was far above
+sea level.
+
+If you look on an enlarged map of northern Montana you will see that the
+Rocky Mountains do not consist of one great, massive range. There are
+ridges and valleys, and plateaus extending for hundreds of miles along
+the British frontier. There are peaks from which the snow never
+disappears, and there are timber lines which crawl almost to the summit
+of other peaks. There are fertile valleys where cattle grow fat, and
+great gorges where beasts of prey await their victims in thickets.
+
+It is the timber on this great stretch of country that the United States
+government is trying to save.
+
+The heat was blistering now, and Ned feared for the safety of his
+gasoline tanks. At a motion from him Frank removed his coat, carefully,
+for a slight movement in the air is sometimes productive of disastrous
+results, placed it over the tanks, after a great effort, and managed to
+saturate it with water from one of the bags.
+
+Through the smoke a line of tree tops now came into view, low down, and
+the boys knew that they had passed the fire line. Ned tried to slow
+down, but found that he must keep the motors going in order to retain
+control of the machine.
+
+"There's a clear space ahead!" Frank shouted, and Ned dropped. Then a
+giant trunk obtruded itself, and the boy tried to dip and whirl so as to
+dodge it, but the pressure of the wind was too strong.
+
+The machine headed straight for the tree, which seemed to Frank to be
+about a thousand feet high.
+
+"Hang on to the first thing that comes to your hands if she strikes!"
+Ned shouted. "But stick to the 'plane as long as she is clear. There may
+be a current of air which will sweep us away from that tree."
+
+"Here's hoping!" Frank gasped back, and then the smoke shut out the
+view, making the situation doubly dangerous.
+
+
+
+
+CHAPTER XV.--TOLD BY THE FOREST RANGER.
+
+
+The rangers, almost exhausted, were fighting the fire desperately,
+hoping against hope, when the cyclone--it amounted at times almost to
+that--struck the forest. Then they knew that the fight was lost for the
+time being.
+
+It was now a question of escaping from the flames they had been battling
+with. The chief foresters knew very well that there was a way to safety,
+but they had under their command many rangers who had joined the service
+merely for the adventures they anticipated meeting, and these, they
+understood, would be hard to manage.
+
+When the order came to drop everything and fall back some of the new men
+accused those in authority of cowardice and kept on in the course mapped
+out for them under entirely different conditions. Two of them even
+insisted on starting back to the rough shanty and preparing dinner. They
+lost their way in the blazing inferno, and their bones were found two
+weeks later, at the foot of a tree which had been burned into a stub,
+but which had not fallen.
+
+When the danger became apparent to Green who was in charge of the
+company found by Nestor, he ordered his men into a "burn" of half a
+dozen acres in extent. By "burn" is meant a patch of forest which has
+been cleared by fire the previous year. This "burn" was entirely
+stripped of trees. The fire had done its work well, but had been checked
+before spreading.
+
+The men could hear trees falling as they dashed along. The fire was
+screaming, the wind whistling and roaring. Coals of fire, driven like
+arrows by the wind, hit the men in the back as they rushed toward
+safety. At last the "burn" was gained, and the men threw themselves face
+down on the ground. At the eastern edge there were large logs which had
+not been entirely consumed, and some of the men lay down behind them.
+
+The air was so hot that it cut the lungs like acid. Above, across the
+old "burn," streamed a river of flame, now racing like a mountain
+torrent, now dropping sullenly back to the west, like a fiery ceiling
+which had been rolled away. On such occasions the fainting foresters
+below could catch a breath of fresh air and a hazy view of the sky.
+
+Some of the men, half crazed by their sufferings, arose to their feet
+and shook clenched hands at the blazing forests, at the brassy sky, and
+the green hills away to the east. Green crept from one to another and
+whispered that the only hope of life lay in keeping on the ground.
+
+Once when he was creeping toward a man who was moaning in anguish and
+despair he turned his eyes upward to the sky, clear for an instant, for
+the wind was wayward after a time, and saw a speck sweeping out of the
+west, dropping lower and lower, whirling in the wind, racing like an
+express train.
+
+"Dan," he whispered to the man he was trying to comfort, "get a brace!
+There's no use of giving up now. Why, man, the fight is won, and Nestor
+is coming back with water!"
+
+"Impossible!" grunted the other. "Impossible--in this wind!"
+
+"Then look," Green said.
+
+A sheet of flame swept over the "burn," lay upon it for an instant like
+a red-hot roof, and then warped and twisted itself away.
+
+"I see," Dan said, looking into the sky again, "but he can't land.
+Impossible--in this storm!"
+
+"Wait and see!" Green said, and sank back to the earth.
+
+The aeroplane circled, high up, like a bird seeking its prey in the
+burning forest. The wind was tolerably steady at that height, but Ned
+knew that when he came into the lower current he would meet conditions
+which he could not understand.
+
+"There's a place to drop!" Frank shouted to him, pointing ahead to the
+"burn," which seemed only a few yards away.
+
+The aeroplane had missed the tree which had threatened it by an inch,
+and had turned upward again, for there were other trees in the way of a
+descent there. The "burn" was the first free spot that had been
+observed, and, besides, it lay inside the line Ned had figured as
+leading to the foresters.
+
+"Hang on!" Ned cried.
+
+The aeroplane plunged down, almost vertically, and Frank felt as if he
+was standing on his head.
+
+"Don't jump when it strikes the ground," Ned commanded.
+
+Watched by a score of anxious eyes--for the foresters under Green had
+all been told of the coming relief--the aeroplane shot down, struck the
+ground at the center of the "burn," rolled swiftly for a few yards, and
+stopped. At that moment the space above filled with flame.
+
+Both boys threw themselves on the ground and waited. When the fierce
+gust was over the men gathered about them eagerly.
+
+"Did you make it?" asked Green.
+
+"Yes," Ned replied. "Get the bags out and distribute the water. Don't
+let the men waste it."
+
+"I'll see to that," cried Green.
+
+Without the water, without the cooling sips, without the wet cloths held
+over nose and mouth, without the saturated sponges laid on scorched
+heads, the men would have died there in the forest. Presently, when the
+consumption of the timber to the west reduced the heat, when the wind
+quieted down in a measure, they were ready for another fight with the
+flames, and it was owing largely to their exertions that the fire was
+extinguished before millions of acres had been burned over.
+
+"It is a dream!" Green exclaimed, that afternoon, as he stood by Ned and
+the aeroplane. "I don't believe yet that you did it."
+
+"I don't see how I did," laughed Ned. "Anyhow, I'm sure I couldn't do it
+again. I guess Providence took the matter into his own hands. Honestly,
+I do not believe any human strength or skill could do what was done with
+the aeroplane to-day. It was a miracle."
+
+"I know of a nervy boy who had something to do with the miracle," said
+Green.
+
+Ned was naturally anxious regarding Pat, Jack and Jimmie, but believed
+they would show up in good form whenever he got back to the vicinity of
+the place where they had been left. When the boys were in camp with the
+rangers that night, Ned asked Frank about Pat's idea of safety after
+refusing to go up in the aeroplane.
+
+"He said he would stay about the valley," Frank replied. "There is
+plenty of provisions there, you know, and Pat is quite long on the
+eats," he added, with a laugh.
+
+"And Jack and Jimmie will be sure to hang about the neighborhood of the
+caves," Ned said. "The Chinese boy, Liu, will be able to care for them.
+If there is enough gasoline in the tanks, I may go back to the valley
+to-night."
+
+"You'd better get some sleep to-night," Frank advised. "I don't know how
+long it has been since you settled down for a night of it. If you keep
+your brain working right you've got to sleep."
+
+"I really ought to go to San Francisco," was the astonishing reply to
+this advice. "I have work to do there."
+
+"What work?" demanded Frank.
+
+"You see," Ned answered, "we have done nothing yet, except discover a
+crime with which we are supposed to have nothing to do. We have brought
+a little water for the fire-fighters, but we came here for a certain
+purpose, and we have not made good as yet. Perhaps, when I get to
+Frisco, I can hunch my wits, as the baseball fans say, and report good
+progress."
+
+"I don't understand what you mean," Frank said.
+
+"I am not sufficiently sure of my ground to attempt an explanation now,"
+Ned replied.
+
+"Of course," Frank said, thoughtfully, "there's the murder case you went
+to Frisco about before. You might look that up again, but I can't see
+where that has any bearing on this forest fire business."
+
+"You may be surprised," Ned said, "when the end comes. Somehow, I have
+an idea that the two crimes dovetail into each other."
+
+"Nothing stirring!" laughed Frank. "They don't seem to me to match.
+Still, you may have information I do not possess."
+
+An hour later, after the not very elaborate supper had been eaten, Green
+came to the little tent which had been set aside for Ned and Frank. He
+had not wholly escaped the dangers of the day unscathed. There were
+burns on his hands and face, and one of his feet was bandaged.
+
+"Shoe burned through," he said, shortly. "I shall have to walk with a
+crutch for several days."
+
+"You won't like that," Ned suggested.
+
+"No, indeed," was the reply, "especially as I would like to be moving
+about in order to see what has happened to the other boys."
+
+"Have you heard from any of the other groups?" asked Ned.
+
+"Howard came in from the north," was the reply. "Three men killed up
+there. The fire caught them unawares. One of my men has gone south, but
+it will be some hours before I hear from him."
+
+"I am afraid there were several lives lost," Ned said. "In the morning
+I'll fly about and see what I can learn."
+
+"What I came here to talk about," Green said, after a pause, "is this. I
+want to know what you think of the Chinks?"
+
+"The Chinese fire-fighters?" asked Ned.
+
+Green laughed quietly for a moment before replying. Then:
+
+"They told you that, did they?"
+
+Ned nodded. He wanted to jump into the subject without waiting for Green
+to have his say, for he was greatly interested, but prudence told him to
+listen to the forester first.
+
+"Yes," he said. "They told me that."
+
+"Also that they were foresters--the men who told the story about the
+Chinks, I mean?"
+
+"Yes, one of them claimed to be in charge of this district."
+
+"Well, you know better than that now, so there is no use in talking
+about that. You saw some of the Chinks?"
+
+"Certainly. I even had the honor of visiting their residence."
+
+Frank laughed, wondering what sort of a story Ned would have to tell him
+when they were alone again.
+
+"It is a wonder you ever got out again," Green said.
+
+"I left under the excitement of the fire," Ned said. "It was easy
+enough."
+
+"Do you know where the Chinks have gone?" asked Green.
+
+"I think I do," was the reply.
+
+"To San Francisco?"
+
+"Yes, some of them. Others to Portland, I think."
+
+"Smuggled in?"
+
+"Of course, though it seems odd that they should want to cross the
+border so far away from civilization. It must be expensive getting them
+in over such a route."
+
+"The men at the bottom of the game are watched," Green said. "Watched so
+closely that they are obliged to keep out of the actual work and do
+their business through unsuspected channels. After this place has been
+raided they will try some other point."
+
+"You know what has been going on then?" asked Ned, surprised that the
+matter, as understood by the forester, had not been reported to him by
+the Secret Service man in San Francisco.
+
+"Yes," was the reply.
+
+"And you have reported to your superior officers?"
+
+Green nodded, and Ned began to feel provoked at the strange attitude
+taken by the government in the matter. Surely he should have been posted
+as to conditions in the district before being sent on.
+
+"Why wasn't I informed of this new element in the case?" he asked.
+
+"Well," Green replied, "the officials have an idea that the men who are
+running the Chinks and the opium in are the men who are responsible for
+the forest fires. In fact, I have so reported to them for a long time."
+
+"Go on," the puzzled boy requested.
+
+"You see," Green continued, "I might go and pick up a couple of dozen
+Chinks almost any month, and capture a lot of opium, and arrest a few
+men caught with the goods on, but, don't you see, that wouldn't end the
+game?"
+
+"I see that," Ned answered.
+
+"There is a man at the head of this game who is working from behind the
+scenes somewhere," Green hastened to say. "I don't know who he is. The
+officials at San Francisco don't know who he is, or where he is. The big
+guns at Washington know just about as much regarding the head center of
+the game as we do. Well, that is what you were sent here for--to get
+down to cases, as I used to say on South Clark street, Chicago."
+
+"It was thoughtful of them not to interrupt the game until I got here,"
+Ned said.
+
+"Yes, I thought so," Green went on. "I thought that any man, or boy,
+coming here to get to the bottom of this thing would want us to leave a
+few ropes hanging out for him to climb down. You found 'em."
+
+"Yes, I found them," Ned replied. "I found the counterfeit foresters and
+the Chinks, as you call them, and I found something else."
+
+"That is what we expected you would do," Green said, after a moment's
+hesitation. "We wanted you to begin without pointers, with a brain free
+of all the unsuccessful schemes which have been worked. You see, I know
+a great deal about it, my boy," he added with a laugh. "I knew, days
+ago, that you would be here. When I saw the aeroplane in the sky I knew
+who was in charge of it."
+
+"What is the next move?" asked the boy.
+
+"That is for you to say," was the reply. "I am under orders to follow
+any reasonable instructions from you. It is for you to suggest
+something."
+
+"Well," Ned said, "that brings me to a point I was studying over when
+you came in. I was wondering if you would detail men to do certain
+things for me."
+
+"Sure I will. If Washington has confidence enough in you to put you in
+charge of the blindest case in history, why shouldn't I have equal
+confidence in you? You bet I'll be there with the oxen when you give the
+word."
+
+"I thank you," Ned replied. "What I want now is men enough to guard two
+points. One is a cave near Lake Kintla, and the other is the cavern
+where the Chinese have been hiding."
+
+"How many men?" asked Green.
+
+"Two to each place. If there is need of more, others should be ready to
+assist."
+
+"I wish you all success," Green said, after the details of the
+surveillance had been arranged. "We have located the tools, and now it
+is for you to let down to bed rock. The government wants the headpiece
+of this game, and believes that you can put your finger on him. Half a
+dozen inspectors have failed, but I have faith in you, boy."
+
+"Well," Ned replied, "I am glad of your confidence, and thankful for the
+help you promise, and will only say that the man behind the scenes will
+soon be brought out. I think I know his 'cue'!" he added, with a laugh.
+
+"Already?" asked Green.
+
+"I am only expressing confidence in the clues I now hold," Ned said in
+reply. "It may be that the next clues I find will point the other way."
+
+Green shook hands with the boys and went to his tent. It was a clear
+night up above the mountain tops, but down where the boys were the smoke
+of consumed forests lay on the ground like the gray ghost of fallen
+trees. Off to the west the summit of the Rocky Mountains--or one of the
+summits--lifted itself above the smudge, standing like a giant up to his
+neck in gray dust.
+
+"Over there," Frank said, "is Pat--hungry, if you want to know, and
+nearer are Jack and Jimmie. I wish we could hear from them."
+
+"If the ground wasn't still red hot back there," Ned said, "Jimmie would
+be sure to find us."
+
+"By the way," Frank said, presently, "what did you mean when you told
+Green that you had a 'cue' which would bring out the man behind the
+scenes?"
+
+"I meant that I have blundered on a clue which promises well," was the
+reply. "And now," he said, yawning, "I'm going to bed. Rather warm, but
+I think I'll sleep, all right."
+
+In five minutes Ned was sound asleep and Frank was about to lie down by
+his side when Green made his appearance. The forester noted the sleeping
+boy and laid a finger on his lips.
+
+"Let him sleep," he said. "And come out here and see if you know
+anything about the fellow that is tampering with the aeroplane."
+
+"What is he doing to it?" whispered Frank.
+
+"Acts like he was preparing to take a trip in it," was the reply.
+
+The words were followed by the rattle of the motors.
+
+
+
+
+CHAPTER XVI.--HOW A CAT TREED A WOLF.
+
+
+Smoke still hung over the "burn." Now and then it was swept aside by a
+gust of wind which seemed now to blow out of the east, and so did not
+come sizzling with the heat of burned forests. The general effect,
+however, was that of a heavy, stifling fog, and Green and Frank crept
+along toward the aeroplane with their hands held out before their faces.
+
+The clatter of the motors had ceased, but the tap-tap of steel on steel
+was faintly heard as they neared the machine. Occasionally the worker,
+whoever he was, ceased his tapping, as if listening.
+
+"He's got his nerve with him," Frank whispered, as they moved along.
+
+"How did he get here?" asked Green. "That is the question that is
+troubling me."
+
+Presently the two came up so that the figure of the man could be
+discerned, standing before the bulk of the planes. Green sprang forward
+and seized him by the arm. For an instant it seemed as if the capture
+would be made without a struggle, then a shot was fired and a crouching
+figure leaped away.
+
+Frank saw the forester fall and leaped toward the retreating figure. The
+race in the darkness, caused by the pall of smoke which followed, was
+short, for Frank was a noted runner and soon overhauled the fugitive. He
+did not attempt to take hold of the man as he came up. He knew that such
+a course might mean an unequal contest, for he was only a boy.
+
+Instead, he dropped to the ground and caught one of the runner's ankles
+in both hands. Naturally the fellow plunged to the ground head-first. He
+turned quickly and leveled a revolver. There was no warning. The shot
+came instantly, the bullet passing over the boy's head as he dropped
+upon the prostrate figure.
+
+With the hand which held the weapon held closely to the ground, Frank
+struggled with the fellow for an instant, filling the heavy air with his
+cries for assistance. The first shot had been heard by the sleepers, and
+help was at hand immediately. The captive was neatly tied by the light
+of Frank's flashlight, and the foresters gathered about, still rubbing
+their eyes.
+
+The "burn" was not all in darkness all the time, for the glare of the
+smouldering embers to the west lighted the place fairly well. Only for
+the smoke the ruddy light would have made a pretty good illumination.
+When the fellow was lifted to his feet an exclamation of astonishment
+came from the group about him.
+
+"Sawyer!" some one cried.
+
+The prisoner dropped his chin for a moment, as if studying out some
+difficult proposition, then faced the others sheepishly.
+
+"I thought I could get away with it," he said.
+
+A cry now came from the men who had hastened to Green's assistance.
+
+"He's dead, I guess," the voice said.
+
+"I didn't shoot to kill," Sawyer exclaimed. "He can't be dead."
+
+"Why did you shoot at all?" demanded one of the rangers, approaching
+Sawyer with threatening fists.
+
+"He was in my way," was the sullen reply. "I have always wanted an
+aeroplane, and I thought this a good time to get one."
+
+"Did you injure the machine in any way?" asked Frank, as Sawyer stood
+gazing furtively from face to face, his black eyes showing fear.
+
+"When I found I couldn't get it off," was the reply, "I loosened some of
+the burrs. It can be repaired easily enough."
+
+"That is more than can be said for you, if you have killed Green," one
+of the men declared, shaking a fist at the prisoner. "If he's dead
+you'll be hauled up on one of these trees."
+
+"You wouldn't dare do that!" Sawyer cried.
+
+"Wouldn't we?" cried the other. "You'll see when we know whether he will
+live or not. How is it, boys?" he continued, stepping toward the spot
+where Green lay.
+
+The man bending over Green was about to reply when Nestor laid a hand on
+his arm. The boy had been awakened at the first shot and had slipped out
+of his tent and over to the side of the wounded man, being the first to
+arrive there.
+
+"Wait," he said, as the ranger looked up in surprise. "Green is not
+seriously injured," Ned went on, "but I want to make that rascal think
+he is."
+
+"What's the idea?" asked the other, glancing from face to face about
+him.
+
+"When he stands under a tree with a rope about his neck," Ned said,
+"he'll tell us the truth about this affair."
+
+"He was trying to steal the machine," the other said.
+
+"Green has a bullet hole through his shoulder," Ned said, "but I want
+you to treat the prisoner as if the shot had been fatal. Kindly carry
+him to his tent."
+
+The command was instantly obeyed, for the foresters all knew why Ned was
+there, and understood that he was the personal representative of the
+Secret Service chief at Washington. Ned then called Frank aside and
+spoke a few words in a whisper. The boy grinned and hastened back to the
+group about Sawyer.
+
+"Nestor wants to talk with Sawyer," he explained, "and wants me to take
+him to his tent."
+
+"We'll take him to Nestor's tent after we get done with him," declared a
+burly forester whose face bore many evidences of the hard fight he had
+made during the fire. "It won't take us long to settle with him."
+
+Frank spoke a few words to the man and he was one of the first to push
+the prisoner toward Nestor's tent.
+
+"If you'll keep those men off me," were Sawyer's first words, "I'll tell
+you what you want to know. They mean to kill me."
+
+"I think there is little doubt about that," was Ned's reply. "Why did
+you want the aeroplane?"
+
+"If you must know," was the reply, "I was sent here to get it, or to
+wreck it so you couldn't use it."
+
+This looked promising, and Ned waved a hand at Frank.
+
+"Throw him out here!" came a gruff voice from the crowd.
+
+"I won't tell," Sawyer went on, "unless you promise to keep them away
+from me. I didn't mean to kill Green, and no court will convict me."
+
+"When did you come here?" asked Ned.
+
+"A month ago," was the reply. "The day you landed in San Francisco a man
+came to my boarding house and employed me."
+
+"He mentioned the aeroplane?"
+
+"Yes, he knew all about it."
+
+"Treachery in the Secret Service, eh?" asked Ned.
+
+"I don't know how he gained his information," was the reply. "He told me
+that he had secured a job for me in the forest service, and that I was
+to join the crew in this district."
+
+"And steal the aeroplane?"
+
+"Steal it or wreck it. There are men with the other crews. You would
+have found an enemy wherever you landed."
+
+This was all very amazing, and Ned wondered how many pitfalls had been
+set for him in San Francisco. He had no doubt that Sawyer was telling
+the truth. The question was as to whether he would tell the story as it
+was from that point on.
+
+"Who was it that engaged you--gave you your instructions?" he asked.
+
+"I don't know," was the reply.
+
+Ned swung his hand again, and a fierce demand that the prisoner should
+be thrown out arose from the group outside. Sawyer shivered and crept
+out of his camp-chair to Nestor's side. His face was deadly pale, being
+sheltered from the ruddy glow of the fires. Just where the men stood
+outside lay a red lance of light, giving a demon-like look to their
+rugged faces.
+
+"If you don't tell me the truth," Ned said, "I can't protect you."
+
+"I tell you I don't know," wailed the frightened man. "I had never seen
+him before. I wanted a job and took what he offered. I didn't think it
+would be so great a crime to steal or wreck an aeroplane."
+
+"What were you to receive for the job?"
+
+"One thousand dollars."
+
+"Hurry up! Throw that sneak out!"
+
+Sawyer, like the coward he was, threw himself down on the floor of the
+tent and groveled at Ned's feet.
+
+"You would know the man again?" asked Ned.
+
+"Yes; I can pick him out of a score of men."
+
+"You will do this willingly?"
+
+"Yes; I'm sick of the whole game. I didn't mean to hurt Green. I wanted
+to scare him away so I could get back to my tent without being
+recognized. That is all I wanted, and I did not mean to hit him at all."
+
+There was a great deal more talk between the two. Ned soon became
+convinced that Sawyer was a weak man, morally and intellectually, who
+would be apt to follow the lead of one stronger than himself.
+
+After Ned had left a guard over the man and visited Green--who was doing
+very well, and laughing over the trick the boy had played on Sawyer--he
+went back to his rough bed, well satisfied with the events of the night.
+
+"By the way," Frank said, crawling into the tent after assisting in
+caring for the wounded man, "I don't understand what you mean by saying
+that you've got a clue which you think will force the man behind the
+scenes out on the stage, in full view of the audience. If there is such
+a clue hovering about I haven't become acquainted with it."
+
+"The clue is hardly well enough advanced to talk about," Ned replied.
+
+"But if you've got a line on the leader of this bunch you've won the
+case," suggested Frank.
+
+"That is what the government sent me here for," Ned replied. "The chief
+of the Secret Service expects me to round up the man responsible for the
+frequent forest fires. I think now that he should have told me that
+smuggling was going on up here, but he may have had a good reason for
+not doing so."
+
+"You know what Mr. Green said," Frank interrupted. "He said the
+government officers wanted you to take the case and find out everything
+for yourself. Perhaps they feared that you would pay too much attention
+to these smugglers, and let the forest fires issue go with scant
+investigation. They might have arrested the smugglers at any time, you
+know."
+
+"Perhaps so," Ned replied, "But that wouldn't have brought the manager
+of the unlawful enterprises into the hands of the law. After all, the
+Secret Service men may have been right in sending me up here without
+instructions or special information. What a laugh they would have had if
+I had failed to discover the Chinamen and the opium."
+
+"Perhaps they wanted to see if you would discover them," laughed Frank.
+"Have you any idea," he added, "that the Secret Service men knew that
+you would be followed in here--that the plans of the government
+regarding your work were known to the outlaws? Do you think they knew of
+the employment of Sawyer and the others by the men at the head of the
+conspiracy?"
+
+"No; I hardly think the man who gave me final orders at San Francisco
+knew that all he did was known to the men he was fighting," Ned replied.
+"The head of the bunch put a good one over on him there."
+
+"And came near putting one over on you, also," grinned Frank. "The
+aeroplane has been attacked twice already, and others are doubtless
+waiting to get a crack at it."
+
+"They will have to hurry up if they do," Ned said, with a chuckle, "and
+you will have to look out for yourself if they succeed, for I'm going to
+have you take me to Missoula in the morning and then go back and collect
+the boys."
+
+"And not come back here again?" asked Frank.
+
+"Not unless we come back for a pleasure trip," was the reply.
+
+"Well," Frank said, "that pleasure trip idea looks pretty good to me.
+Why not?"
+
+"I may have time," Ned replied.
+
+Frank threw himself on the blankets which had been provided by Mr. Green
+and closed his eyes, which were still smarting from the effects of the
+smoke.
+
+"If you go away to-morrow," he said, presently, "what is to become of
+the clues we found in the cavern by the lake?"
+
+"All provided for," Ned answered.
+
+"And all the Chinks, and everything you discovered while visiting them
+in the caves almost under the divide?"
+
+"Everything provided for," Ned said, sleepily.
+
+"And you think you can close this case by going to San Francisco?"
+demanded Frank, a touch of sarcasm in his tone.
+
+"Go to sleep, little boy," said Ned, in a tantalizing tone.
+
+"But do you?" insisted the boy.
+
+"Of course I do," was the muttered reply. "Go to sleep, little man!"
+
+And Frank tried to obey, but sleep would not come. The fire still
+smouldered over in the west. The ruddy light of the embers was still
+touching the camp with its red fingers. The smoke was still asserting
+itself in the air. The puzzle was still there!
+
+After the boy had rolled over at least fifty times, and arose to consult
+a water bag at least a dozen times, he seated himself under the flap of
+the tent and looked out. There was a moon now, and the smoke only half
+hid it. Far off in the woods wild creatures were expressing their
+opinion of the fire and the wanton destruction of their homes. There was
+a faint rustle in the foliage of the trees east of the "burn."
+
+"Gee!" the boy muttered. "I'd like to come back here for a month!"
+
+Then his attention was attracted to the savage growl of some animal in
+the thicket beyond the fire limit of the "burn." It seemed to the boy as
+if some man-eating creature had cornered a bit of animate supper, but
+couldn't reach it. The language used by the forest resident seemed to be
+in the tongue of the panther. While he listened a cry which was not that
+of a hungry beast came out of the gloom.
+
+That was a cry for help, surely. Frank put his revolver and his
+searchlight into convenient pockets and set out for the scene of the
+disturbance, without awakening any of the sleepers. It was slow work
+pushing through the bushes, and the boy wondered if a fire there, well
+guarded on a quiet day, wouldn't be a good thing.
+
+He kept his searchlight ahead and looked about for the source of the
+noises as he advanced in the darkness. In a short time he heard a voice
+he knew, but hardly expected to hear there.
+
+"Hurry up!" the voice said. "I'm goin' to tumble out of this tree in
+about a minute! I'm that hungry! I thought you might meet me with a pie
+under one arm."
+
+"Well, why don't you come down, then?" Frank asked.
+
+"If you'll turn your honorable attention to that tree to the east,"
+Jimmie said, "your excellency will observe a panther waiting for his
+supper. He's been tracking me all day, getting bolder every minute. Now,
+if I turn this searchlight away for an instant, he'll jump on me, and
+there you are. No more Jimmie McGraw than a rabbit!"
+
+"I didn't see your light at first," Frank said, "for it was hidden by
+the foliage of the trees. I suppose you want me to shoot the cat?"
+
+
+
+
+CHAPTER XVII.--THE TIME FOR THE ROUND-UP.
+
+
+"Sure," Jimmie answered. "Shoot the cat!"
+
+"Well, keep your light on him, and wait until I can get where I can see
+him. The cat frequently resents being wounded."
+
+"Cripes!" cried Jimmie. "Don't shoot unless you kill him, for he'll jump
+at me then for sure. He's angry now--hear him pound with his tail? I
+fired all my loads at him an' he dodged the bullets."
+
+"You couldn't shoot craps!" scorned Frank.
+
+The panther, a great brute made ferocious by the excitement of the fire,
+and probably scorched a little, could now be heard moving in the
+branches of a tree not far from that in which Jimmie was perched. In a
+moment Frank reached a point from which the beast's face could be seen.
+
+He thought to himself that it looked like a tiger head fastened against
+a gray cloud with unseen pins. Jimmie's searchlight brought the evil
+face, the cruel eyes, the back-sloping ears, the faintly-moving jaws,
+out into strong relief, as the circle of flame was only large enough to
+cover the face.
+
+The beast heard Frank moving in the bushes below and turned its head to
+look, at the same time crouching low, as if to spring.
+
+The first bullet struck him fair in the throat, the second entered the
+head just above the eyes, the third, coming so rapidly on the others
+that the three reports seemed to merge into one, entered the body over
+the heart. The great beast was dead when the body struck the ground.
+
+Jimmie was not long in getting down to Frank's side and grasping him by
+the shoulders in a hug which threatened to end in a scuffle.
+
+"Get away!" Frank said. "Suppose there's another cat here? If there is
+he'll get one of us through your foolishness."
+
+"There were two," Jimmie said, coolly, "but I killed one."
+
+"How did you get here?" was the next question, asked as the boys turned
+toward the camp.
+
+"How do you think I got here?" returned Jimmie.
+
+"Walked!" laughed Frank.
+
+"Yes, I walked."
+
+Jimmie stopped and rubbed his legs with careful hands.
+
+"I'm all wore out!" he said. "I can't walk any farther to-night."
+
+"All right," Frank said, with a grin. "I'll leave you both lights to
+keep the cats off with, and my gun, and come out after you in the
+morning after breakfast."
+
+"Oh, my eats!" Jimmie cried. "Lead me to something that will sustain
+life! I'm starving, I tell you."
+
+"You walked all the way?" asked Frank.
+
+"Sure! Forty miles at least."
+
+"Where are the others?"
+
+"Pat, Jack and the Chink Scout? Pat came up just before I started,
+riding on a burro, an' in the custody of a small party of rangers, who
+thought he had been setting fires. The rangers went into camp over
+there, all tired out, an' Jack an' Pat settled down with them. I run
+away."
+
+"They don't know where you are?" asked Frank.
+
+"Nix know!" replied the boy.
+
+"But how did you ever get through the burning forest?" asked Frank,
+hardly believing the boy's story of his long walk.
+
+"This 'burn' is only a mile wide," Jimmie said. "I walked on the south
+edge of it. Say, there are plenty of lives lost! Bears, an' cats, an'
+all that. I guess this will be an agreeable place to live in about a
+week--not!"
+
+The boy was indeed "all in," as he expressed it. He had walked since
+early morning through a tangled forest black with smoke, through an
+atmosphere burned and smoked out of its life-giving qualities. And all
+this exertion in order that he might be near his chum, Nestor.
+
+Fortune had favored the lad, and he had at last blundered on the camp
+where Ned had taken refuge, otherwise he might have died in the forest
+from hunger and exhaustion, or been devoured by some of the savage
+beasts which had followed him all day.
+
+"Where's Ned?" Jimmie asked, as they stood before the little row of
+tents.
+
+"Asleep," was the reply, "and you let him alone for to-night. He's been
+having a lively time. But how in the name of all that's wonderful did
+you ever find your way here?" the boy added.
+
+"I don't know," was the reply. "I knew that Ned would be wherever the
+fire was, and so started east. Not so very long ago I heard a couple of
+shots, and that directed me toward the camp. Who was hurt?"
+
+Frank explained, briefly, what had taken place, hunted up a liberal meal
+for the boy, and then saw him settled for the night.
+
+Ned's astonishment at seeing the boy in the morning may well be
+imagined.
+
+"Huh!" Jimmie said. "You thought you would fool me out of all the fun!"
+
+Ned laughed and asked about the others, finally informing Jimmie that he
+was leaving that morning for San Francisco by the aeroplane route.
+
+"Then I'm goin'!" declared the boy. "I'm not goin' to be chucked into
+the discard again."
+
+"You'll have to sit in Frank's lap," grinned Ned, "and the machine may
+tip over with such a load, at that."
+
+"I guess it didn't tip over when Frank and Jack an' yours truly run it,"
+Jimmie replied. "Anyway, I'm goin' with you."
+
+Before leaving for Missoula, where he was to surrender the aeroplane to
+Frank, Ned had another long talk with Mr. Green, whose wound was not so
+serious as it had been considered the night before. The forester told
+him what he knew of the men under the leadership of Greer, saying that
+he might have arrested Greer at any time during the month, and, what is
+more, convicted him of smuggling both Chinamen and opium over the
+border.
+
+"But what good would it have done?" Green went on. "The conspirators in
+Washington, or New York, or San Francisco would have chosen another
+leader, and the game would have gone on as before."
+
+"That is very true," Ned admitted, "and still, it seems to me that the
+time to round the fellows up has come!"
+
+"Do you give that as an order?" asked the other, a flash of excitement
+showing in his face.
+
+"Yes," was the reply.
+
+"But some of them have gone to Portland with the Chinks--some to Frisco,
+I think. What about that?"
+
+"If you can spare men," Ned said, "follow them."
+
+"You're on!" laughed Green. "I've been waiting for some such orders for
+a long time. You're on!"
+
+"And follow on to Frisco as soon as you can," Ned continued. "Address
+me, or look for me, if you are able to be about after you get there, at
+the Federal building."
+
+"I'll be there in a week," Green said, his eyes showing the joy of the
+coming fight with the outlaws, "and I'll have a bunch of prisoners with
+me."
+
+The forester hesitated a moment, as the importance of the proposed move
+came to him, then faced Ned with a hesitating look. It was plain to the
+boy that Green wanted to ask a question which he believed to be either
+personal or impertinent.
+
+"Is there something else?" Ned asked.
+
+Green still hesitated, his eyes on the ground.
+
+"Are you sure of your clues?" he asked, then.
+
+"I think so," was the reply.
+
+"Because, you see," Green went on, "the government doesn't want any trap
+sprung until the whole bilin' is within reaching distance. After the
+good work you have done here, I wouldn't like to have you order the
+round-up and then find that the men you wanted were still out on the
+range."
+
+"Thank you for your frankness," Ned replied.
+
+"I just want to be sure that you are sure," smiled Green. "It would mix
+things for me to make these arrests and have the big ones get away, now,
+wouldn't it?"
+
+"Indeed it would," Ned admitted, "but I think it is safe to go ahead as
+we planned a moment ago."
+
+"All right!" Green said, but there was still doubt in his eyes.
+
+"And I'll accept all the responsibility," Ned added.
+
+"I have a suggestion to make," Green said, then. "Why not go on to
+Frisco in the aeroplane and ask for instructions? You can make the trip
+in the airship in no time, but it is a long ride by rail."
+
+"I think," Ned replied, with a laugh, "that the game will be ripe just
+about the time I get to Frisco by rail. Besides, I don't want the
+outlaws to know that I'm going to the city. They would know it if they
+saw the aeroplane making for the coast. Well, if I leave Frank
+navigating it in this district they will think I am still here. Don't
+you see?"
+
+"Go it!" laughed Green. "I reckon you know what you're about."
+
+"Anyway," Ned said, "I've got to play the game in my own way if I play
+it at all."
+
+"I see," observed Green, and the two parted.
+
+The aeroplane had not been damaged at all by the fire, but Ned went over
+it carefully before attempting a start. Sawyer, trembling with fright,
+was brought out to show where he had meddled with the machinery.
+
+"I didn't harm it any," the prisoner said.
+
+"There are some burrs missing," Ned said.
+
+Sawyer brought half a dozen out of a pocket and passed them to Ned with
+a reluctant hand.
+
+"I neglected to tell you that I had them in my pocket," he said.
+
+"What did Green say to you this morning?" asked Ned, screwing the burrs
+on where they were needed.
+
+"He says he won't be hard on me, if I tell all I know about the men who
+are doing these tricks," was the reply.
+
+"You told me all you know?" asked Ned.
+
+"Yes, there is nothing else to tell. I'm so glad to think that Green is
+not going to die from the wound I gave him that I'll do everything in my
+power to bring the men who put me up to this to punishment."
+
+"Sure you can identify the man who hired you?"
+
+"Dead certain," was the reply.
+
+"Then I'll have one of the men bring you to Frisco," Ned said. "You will
+be wanted there."
+
+"All right; anything the government wants goes!"
+
+In half an hour the three boys, Ned, Frank and Jimmie, were on the
+aeroplane, sailing through the clear air of a splendid summer morning.
+Below they could see the long, narrow strip of land which had been swept
+by the fires. Off to the north was the British frontier, with Lake
+Kintla glimmering in the sunshine.
+
+"Aren't we going back to that lake cavern again?" asked Frank.
+
+"Not just now," Ned replied.
+
+"I didn't know that you got all you wanted in there," Frank went on. "I
+had an idea that you were trying to identify the man we found dead
+there."
+
+"I think I learned all there was to learn there," Ned replied.
+
+"He spent a lot of time in there before he went to Frisco," Jimmie said.
+"He made me go in there with him, and I didn't like it."
+
+"And so no one will ever know who the dead man was?" asked Frank.
+
+"I have been given a name," Ned said, "a name to call him by, but I
+don't exactly like to accept the information, considering the source
+from which it came."
+
+The aeroplane drifted to the west and north easily under the steady
+pulse of the motors, and the plateau where Jimmie had left the boys and
+the foresters was soon in sight.
+
+"I wonder if they're all alive?" said Jimmie.
+
+"What could happen to them?" demanded Frank.
+
+"Oh," Jimmie replied, with biting sarcasm, "there is nothing here to
+harm 'em! This is a pink tea, this is! This is a church fair, where you
+get ices made out of the cream they skim off the cistern!"
+
+"You're getting nutty!" Frank said, with a grin.
+
+"When I left 'em," Jimmie went on, "the boys an' the foresters were
+wondering if the outlaws would come back an' kill 'em one by one or just
+blow up the caves underneath the plateau an' send 'em up in the air
+without any good means of gettin' down."
+
+"Then we'll look them up," Ned said.
+
+The great divide lay down below, and the plateau was in plain sight,
+with the early sunshine streaming over it. When the aeroplane circled
+about it a shout came up to Ned's ears, then a shot, and the powder
+smoke drifted lazily upward in the clear air.
+
+"Somethin' doin'!" Jimmie cried. "Suppose we go down an' see."
+
+
+
+
+CHAPTER XVIII.--TWO INANIMATE WITNESSES.
+
+
+It was very still in the bachelor apartment, and, as on the occasion of
+his previous visit, Nestor saw, as he slipped through the doorway
+leading from the private hall, that the lights were burning low.
+
+On this night there was no opium-drugged victim lying on the couch.
+There was a movement in the room beyond, and Ned could hear the soft
+tread of slippered feet and occasionally the rattle of dishes. It was
+evident that midnight luncheon was being prepared, and that the master
+of the habitation would soon be on hand.
+
+Closing the door softly--the same having been opened with a skeleton
+key--Ned stepped across the room to the writing desk which he had
+examined on that other night. After searching the half-open drawer for
+an instant, he took out a number of papers and examined them. He also
+took a check-book out and put it into a pocket. The papers he returned
+to the desk. The check-book was an old one, there being few blank checks
+in the binding, but plenty of stubs.
+
+Then Ned looked at the lock of the desk. It had been out of repair at
+his previous visit, but was in excellent shape now. He removed the new
+key and inserted the one with the broken stem which had so excited the
+interest of Albert Lemon and Jap on occasion of his previous visit.
+
+The key with the broken stem did not fit. A new lock had been put on.
+Next Ned went to a mantel over a gas grate and lifted the cover from a
+little ivory box which stood there. At the very bottom of the box, under
+buttons, pins, needles, and odds and ends, he found a key. This one was
+whole, and it was an exact duplicate of the one with the broken stem.
+
+Ned had been in San Francisco three days, and Jimmie was not far away.
+On bringing the aeroplane to the plateau on the day of his return to
+Missoula he had found Ernest Whipple, Jack, Pat, Liu, and a small party
+of rangers anxiously awaiting him. Also "several tough ones waitin' for
+an introduction," as Jimmie put it. It seems that the fake foresters had
+returned to the cave after the fire in the caņon had burned itself out
+and had at once discovered that the prisoner had vanished, also that
+Liu, the Chinese boy, had disappeared with him.
+
+There had been a long search for the missing boys, as the outlaws knew
+very well that the escape meant the bringing of officers to the caves,
+but they had not been discovered until a short time before the arrival
+of the aeroplane.
+
+When Ned reached the plateau--in fact, before he reached it--he heard
+the whistling of bullets aimed at the big bird. The outlaws were trying
+to cripple the aeroplane and so give the riders a tumble. The boys
+landed in safety, however, and joined the others.
+
+Seeing the boys thus reinforced, the outlaws had withdrawn, and the
+rangers had conducted them to a pass which led over the divide. So it
+was that Ned had left them, making their way down toward the Valley of
+the Wild Animals, where a large number of rangers were encamped, and
+where Frank was to come for them with the aeroplane as soon as Ned
+landed at Missoula.
+
+There were numerous shots fired at the aeroplane as it mounted into the
+sky again, but no harm was done.
+
+"If they had been shootin' at that cat last night," Jimmie said, in
+derision, "they would 'a' been eaten alive."
+
+"They are nervous," Frank said, "and don't dare come out of their hiding
+places so as to get a good sight at us. They are afraid of the rangers,
+and afraid that we'll drop a bomb or something of that sort down on
+them."
+
+This explanation of the bad marksmanship, as well as the failure of the
+outlaws to rush the aeroplane, was accepted by the boys, who had
+anticipated a fight with the fellows. It was afterwards learned, too,
+that there were only half a dozen outlaws in the group, and that they
+had been sent back to guard the caves and not to fight rangers unless
+they were attacked.
+
+Ned had been very busy since his return to the city, having made many
+inquiries concerning Albert Lemon and his servant, the Japanese
+attendant who had given the boy such a chilly reception on the night of
+the first visit.
+
+Lemon, he had been informed, was a millionaire of eccentric habits.
+According to Ned's source of information, he would absent himself from
+his usual haunts for days at a time, and would then return to shut
+himself up in his rooms, at home to no one, and attended only by Jap.
+
+After a time the clatter of dishes grew louder in the adjoining room,
+giving notice, doubtless, that the luncheon being prepared was nearly
+ready to serve. Then the boy seated himself behind a screen which cut
+off a corner of the room and waited. He had occupied his retreat only a
+short time when a key turned in the door and the man he had talked with
+on his first visit entered.
+
+It was not the old, half-dazed, disreputable Lemon who stepped into the
+room, but a young man handsomely dressed and evidently very wide awake
+and in the best of spirits. After seeing that the window shades were
+closely drawn he turned on the lights and dropped into a chair at the
+writing desk.
+
+Ned saw him rummage the pigeon-holes for a moment, extract a folded
+paper, and fall to checking off the items. The boy had examined this
+sheet while at the desk, and so knew what it contained. After checking
+the items the man drew out a long pocket-book and placed its contents on
+the writing board.
+
+The boy gave a quick start when he saw what the book had contained, for
+a large package of yellow-back bank notes lay exposed to view. The man
+counted them carefully, compared the total with the figures he had
+marked on the sheet, and then sat back in his chair with a satisfied
+smile on his face.
+
+"Everything correct!" he said.
+
+Then he lighted a cigar and turned to the door opening into the inner
+room.
+
+"Jap!" he called softly. "Oh, Jap!"
+
+The door opened and the servant looked in.
+
+"Come here!" Lemon commanded. "What have you been doing?" he added, as
+the Jap stood before him.
+
+"Nothing," was the reply.
+
+"You are not telling the truth," Lemon said. "You have been seen about
+the city, in tea houses, talking with strangers."
+
+"I have not been out of the rooms," the other insisted, stubbornly.
+
+"Let it pass," Lemon said, in a moment. "There may be some mistake. Any
+one been here?"
+
+"No one."
+
+The servant appeared to have a perfect knowledge of English. He looked
+into his master's face with a bland smile, but now and then his eyes
+sought the screen behind which Ned was hidden.
+
+"Well, some of the boys will be up here to-night," Lemon said. "See that
+there is plenty to eat. Go, now."
+
+The servant turned to the door opening into the private hall, stood with
+his hand on the knob for an instant, and then, apparently changing his
+mind, went out through the doorway by which he had entered. If Lemon had
+been listening intently he would have heard a quick movement in the back
+room as Jap closed the door.
+
+In a moment there was another movement in the private hall, and then Ned
+heard the corridor door open. He pushed the screen aside and stepped out
+before the astonished occupant of the rooms.
+
+"What does this mean?" Lemon demanded, a quiver of excitement--or it
+might have been consternation--in his voice.
+
+While he spoke he moved toward a table where a revolver lay in full
+view.
+
+"Never mind that," Ned said, coolly. "We can arbitrate our differences
+without its assistance. Besides, it is not loaded."
+
+"What are you doing here?" Lemon almost shouted, his face growing white,
+either with rage or fear. "Leave the room immediately."
+
+Ned dropped into a chair and motioned toward another.
+
+"Sit down!" he ordered.
+
+"Your impudence is amazing," Lemon said, but he took the chair.
+
+In a moment, however, he turned to the door.
+
+"Jap!" he called.
+
+Again the door opened and the servant looked in.
+
+"Are you armed?" Lemon asked.
+
+The servant nodded, fixing a pair of inscrutable eyes on Ned's face as
+he did so.
+
+"Very well," was the reply. "Stand there by the door. How did this man
+gain entrance here?"
+
+The only reply was a shrug of the shoulders.
+
+"Let it pass for the present," Lemon said, with a smile of triumph.
+"Stand there and shoot when I give the word."
+
+The servant nodded again. Ned remained seated, his eyes fixed coolly on
+the face of the master.
+
+"Now, what do you want?" demanded Lemon. "You don't look exactly like a
+common sneak thief."
+
+"You doubtless remember," Ned began, in a level voice, "that I did
+myself the honor of calling at these rooms not long ago in quest of
+information of one--of one Felix Emory?"
+
+Lemon started at the name, but gained confidence as he glanced toward
+the servant at the door.
+
+"Yes, I remember," he said. "What about it?"
+
+There was a sharp ring at the corridor door before Ned spoke again. The
+Jap looked inquiringly at his master.
+
+"Company may prove of value just now," Lemon said. "Will you see who is
+there?"
+
+It was clear to Ned that Lemon expected some of the associates he had
+mentioned as "the boys" when giving instructions about the luncheon, and
+there was a smile of welcome on his face when a bustle in the hall told
+of an arrival.
+
+There was only one man, however, and Lemon at first seemed disappointed,
+but in a moment he had his face under perfect control again.
+
+"Father!" he cried, springing to his feet. "It is good to see you here!"
+
+The newcomer, a man of perhaps sixty, well dressed and with the air of a
+man to whom marked attention was due, stood looking into Lemon's face
+for an instant and then grasped his hand.
+
+"You have changed little, my son," he said.
+
+Lemon smiled and indicated Ned with a slight motion of the hand.
+
+"Permit me to present to you my father, Mr. Leon Lemon," he said, "and
+this, father, is a boy burglar who broke into my rooms in quest of
+plunder a short time ago," he added. "We were having quite a cheerful
+talk when you came. I don't know his name, unfortunately."
+
+The old gentleman gave a start and attempted to rise from his chair.
+
+"Don't distress yourself," Lemon said. "He is quite harmless. Besides,
+Jap has him covered with the cannon he delights to carry."
+
+"This is a strange situation," the other said, wiping the sweat of
+excitement from his face.
+
+"One of the incidents which add to the joy of life," Lemon said. "You
+remember Felix Emory?" he added. "Well, his pretense for this call is
+that he came to ask about him. Go ahead, Mr. Burglar."
+
+"Perhaps you will also remember," Ned went on, "that on my former visit
+here I exhibited a key with a broken stem--the key to that writing
+desk?"
+
+Lemon's face hardened and he glanced furtively at the servant, but said
+not a word.
+
+"This key," Ned said, producing the one mentioned, "was found in the
+pocket of the man who was found dead in the Rocky Mountains. You think
+you left it in the suit of clothes you gave Emory?"
+
+"Possibly," was the strained reply. "But we have had enough of this,"
+Lemon added. "Call the police, Jap."
+
+"Just a moment," Ned went on, when the Jap moved toward the door. "When
+you could not find the key, Mr. Lemon, why didn't you use the duplicate.
+The duplicate you kept in the box on the shelf? Why did you think it
+necessary to break the lock?"
+
+"The servant did that," was the angry reply.
+
+"I see," Ned replied, coolly, "perhaps that was done while you were up
+in the mountains with Emory--before he was killed?"
+
+"Possibly," Lemon gritted out.
+
+"Now, since talking with you," Ned continued, "I have been up in the
+mountains. There I found a man using a typewriter. By the way, have you
+a machine here?"
+
+"Certainly not," was the angry reply.
+
+"But you formerly used one here?"
+
+"Never!" was the reply.
+
+"That is strange," Ned said, "for when I came in here not long ago I
+took the liberty of looking through some papers in your desk, for which
+I ask your pardon. Well, I discovered that the machine you used here
+carried a defective letter 'c.' It looked in the writing like an 'o.'
+The machine the man was using under the divide had the same defect. If
+you will observe the sheet you were examining a few moments ago, you
+will note the imperfect letter."
+
+Lemon's teeth clinked together sharply, but he did not speak.
+
+"When I came here last," Ned continued, "you lay in an opium stupor on
+that couch. You had recently returned from a trip to Lake Kintla, where
+Emory was found dead. While in that section you visited a cavern on the
+eastern slope of the divide. There is where you used the typewriter
+taken from these rooms."
+
+"My son never learned the keyboard," said the old gentleman, an angry
+snap in his eyes. "He has never found it necessary to earn money."
+
+Lemon turned to the old man and bowed, gratefully.
+
+"When you lay on the couch that night," Ned continued, "there was the
+smear of the typewriter on the middle finger of your left hand, close to
+the nail. I use a double keyboard machine myself, and sometimes smut my
+finger on the ribbon when I turn the platen. Some papers I chanced upon
+in the mountains bear the mark of a smudged hand. You are careless in
+using the machine. You even left a blue record ribbon in the cave
+headquarters where the dead man was found. That was my first valuable
+clue!"
+
+"What papers did you steal while in the mountains?" demanded Lemon,
+springing to his feet, his face deadly white, his fists swinging
+aimlessly in the air.
+
+"Lists," Ned replied. "Lists of Chinamen brought from over the border,
+and lists of opium cases smuggled in. I have the papers in my possession
+now. They match with the statement you examined just before I made my
+appearance in the room--just before you counted the money you received
+from this illegal traffic."
+
+The old man leaped at Ned, but the boy moved away and stood by the door.
+The Jap stepped closer. There came a sound of whispering, a noise of
+footsteps, from the hall outside. Then the door was opened and Greer,
+Slocum, Chang Chee and two others entered, glancing keenly at Ned as
+they passed him, still standing by the door.
+
+"Do you mean to accuse my son of crime?" shouted the old man, not
+noticing the new-comers in his rage and excitement. "You scoundrel!"
+
+"How do you know," Ned asked, with a smile at the others, "that this man
+is Albert Lemon, your son?"
+
+
+
+
+CHAPTER XIX.--THE MAN BEHIND THE SCENES.
+
+
+"Not my son!" shouted the old man. "This has gone quite far enough! Jap,
+call the police, and order this mad youngster taken away."
+
+The younger man broke into a harsh laugh and turned to those who had
+just entered. Slocum and Chang Chee were whispering together, and a
+dangerous looking knife showed in the hand of the false ranger.
+
+"You hear what father says, boys," Lemon said. "Remember that."
+
+"What is this kid doing here, anyway?" demanded Slocum.
+
+"He came here, evidently, for the purpose of blackmailing me," Lemon
+said. "He has papers stolen from the mountains--lists, he says they
+are--and they should be taken from him by force."
+
+Slocum and Chang Chee started toward the boy, but he waved them back
+with his hand.
+
+"I will lay the papers on the table," he said. "You are quite welcome to
+them for the present."
+
+"I'll take him down to the police station," said Chang. "He ought not to
+be at large. Come, youngster."
+
+"You seem to be able to talk pretty good English now," laughed Ned.
+"Much better than the slang you gave out in the mountains."
+
+"Come!" shouted the Chinaman. "You are here alone, so there is no need
+of a fight. Come along!"
+
+"We'll see about my being here alone presently," Ned said. "Anyhow, I'd
+better be here alone than with any one of you in the dark streets. I
+should be murdered before a block was passed. That is what you came to
+Frisco for, to murder me--just as the man in the lake cavern was
+murdered."
+
+Those in the room looked at each other and remained silent. There was a
+tense moment, when every person there seemed gathering for a spring,
+when the lust of blood seemed in every glaring eye, but it passed.
+
+"Where are the Chinamen you brought away from the British border?" asked
+Ned of Chang Chee. "Are they in this city? Oh," he continued, as Chang
+glared at him, "we knew that you were about to bring in a batch. You
+usually light forest fires in order to attract the attention of the
+rangers when you get ready to unload a band of Chinese on Uncle Sam.
+That is Doyers street cunning, Chang!"
+
+"You see," he went on, "we have had the good luck to discover why the
+forests in Northern Idaho and Montana have been set on fire so
+frequently. I don't care to say what I think of the wisdom of your
+course in so attempting to hide your movements, except that it attracted
+attention instead of diverting it. You firebugs might have been arrested
+long ago," he continued, turning to Slocum, "but it was thought best to
+wait until the head center of the whole conspiracy was in the hands of
+the law. Now that this has been accomplished, I may speak."
+
+The people standing around the boy looked into each other's faces, and
+there was a movement as if to draw weapons.
+
+"Permit me to congratulate you on the discovery of the leader of the
+outlaws," the old man said with a snarl. "Perhaps you will be kind
+enough to give us his name?"
+
+"There are no objections that I know of," was the reply. "His name is
+Felix Emory. You may have heard of him."
+
+"An old acquaintance of my son Albert," the old man said.
+
+"That is the name of the man who was so mysteriously murdered in the
+Kintla lake cave," Slocum observed. "Why do you place the crime on the
+dead?"
+
+"Felix Emory," Ned said, "is not dead. He is alive at this moment--alive
+and in this room!"
+
+The young man broke into a jarring laugh and turned to the old man.
+
+"You remember the strange resemblance between Felix and myself," he
+said. "Well, it seems to have deceived this clever young man. By the
+way, Slocum, why don't you take the lad to the police station? We have
+no more time for him here."
+
+Slocum and another sprang forward, but Ned opened the door with a quick
+motion and stood beyond their reach.
+
+"The man found dead in the cave," the boy said, facing the old man, "had
+met with an accident in his youth. The first joint of the little finger
+of the right hand was missing. Also, there was a scar over his left
+eye--a trifling scar, made with a knife in the hands of a playmate. Do
+you recall these marks of identification, Mr. Lemon?" he added.
+
+The old man threw his hands to his face and stood silent for a moment
+while the others looked on in perplexed silence. When he uncovered his
+face again he stepped forward to the man he had called his son on
+entering the room.
+
+"Let me see your hands, Albert," he said, kindly. "Bend down so I can
+see the scar on your forehead!"
+
+"Step aside, you old fool!" the young man cried, pushing the old man
+back rudely. "We have had enough of this, boys," he continued, turning
+to the others. "The game is up unless we get rid of this dotard and this
+boy. Why don't you get busy?"
+
+The old man dropped into a chair and lifted his face to Ned's.
+
+"You found my son murdered?" he asked. "Then this man Felix Emory stands
+in his shoes! Even I was deceived by him! Why, he has been calling upon
+me for large sums of money during the past month. He has taken
+possession of my boy's rooms. Was it this man Emory who killed him?"
+
+"We believe so," was the reply. "The proof is within reaching distance."
+
+"Out with them both!" shouted Emory.
+
+"Your son Albert took this man in and tried to do something for him,"
+Ned went on, "and was robbed and murdered for his pains. This man Emory
+was the leader of this choice band of smugglers and firebugs when he
+came to your son. The band was on the point of scattering because the
+officers were close on their track. They needed a man well up in the
+world--a man against whom the breath of suspicion had never been
+blown--to represent them in the opium market and the smuggled Chinamen
+market. They sent this man Emory to your son with a proposition, and he
+turned him down. Then they parted. But Albert knew too much and so he
+was lured to the woods and killed, and Emory stood before the world as
+your son. It was a devilish plot, great wealth being the object. If you
+will look at the stubs in this check-book you will see the difference in
+the hand-writing."
+
+"I rather admire your nerve, boy," Slocum said to Ned. "You've got the
+right kind of courage to stand up here and tell all this to us. You know
+very well that we can never let you go out of this place alive? That
+even this old man must suffer for your bit of foolish daring?"
+
+"I'd like to have the training of that kid for a few years," Chang said.
+"I could beat the world with him!"
+
+"Well, you all know what we've got to do," Emory said, angrily. "We've
+got to get rid of the boy and this old man. If we do not, there is an
+end of a rather profitable business. Besides, with Albert Lemon dead, I
+become his heir, with no possible chance of being identified as Felix
+Emory."
+
+"You devil!" shouted the old man. "You murderer!"
+
+Enraged by the exclamation, Emory made a rush for the old man, but was
+stopped by a voice from the doorway opening into the rear room.
+
+"That'll be all for you!" the voice said.
+
+It was Jimmie who stood in the doorway, smiling, and making about the
+worst bow a Boy Scout ever made.
+
+"Don't wiggle about so, gentlemen," he added, "for the men behind this
+partition have you all covered with repeating rifles, and some of them
+are nervous. Stand still while a friend of mine presents you with
+wristlets."
+
+Jap turned and faced the frightened group and then pointed to the wall,
+near the ceiling, where a line of two-inch holes were seen, at each hole
+a shining eye.
+
+"You see," he said, "I cut those holes there to-night, so the boys
+wouldn't have to lie hidden under the furniture. There's a gun behind
+every one of them. And now, with your permission--"
+
+Jimmie passed out a bunch of clattering, ringing handcuffs, and Jap
+slipped them on the wrists of the prisoners. As he did so Frank came
+dashing into the room, swinging his cap aloft. Ernest, Jack, Pat and Liu
+were there, too, overjoyed at the great victory.
+
+"Wow!" he cried. "Here's a wire saying that the bunch was captured at
+Portland to-night, and another from Missoula says the men left in the
+caverns were caught yesterday. I have the honor to report, Mr. Sherlock
+Holmes Nestor," he added, with a low bow, "that the round-up is
+complete."
+
+"Our day will come directly," Emory shouted. "You haven't a word of
+proof against any of us. Your story sounds all right here, but wait
+until you get into court. Our lawyers will pick your yarn apart like a
+rag doll. And you, Jap," he went on, turning to the servant, "when did
+you turn against me?"
+
+"There have been two instances of false personation in this case," Ned
+said. "You, Emory, personated Albert Lemon, whom you murdered, and you,
+Jap, personated the servant Emory brought here after he had seen you
+carried out of the rooms for dead."
+
+"Then that isn't my servant at all?" asked Emory.
+
+"I was in the employ of Albert Lemon," answered the Jap, "when you took
+him away and killed him. When you came back from the mountains you
+caused me to be drugged and killed, as you supposed. But your servant
+hesitated in the work. He finally turned against you, and permitted me
+to come here in his stead. It was he who disclosed the hiding place of
+the duplicate key. He told me, and I told Mr. Nestor."
+
+"It is all a blackmailing conspiracy!" cried Emory.
+
+"When Mr. Nestor came back to the city, three days ago," the servant
+went on, "I was told by the man I was personating in these rooms that
+the whole plot was known. He said that Mr. Nestor knew that you were not
+Albert Lemon, also that I, Albert Lemon's servant, still lived. I didn't
+have much to tell him when he came to me, but I told him all I knew."
+
+"And you let him search my rooms?" cried Emory.
+
+"Of course," was the cool reply. "He has everything required to send you
+to the gallows for the murder of Albert Lemon, and everything necessary
+in the case against the smugglers and firebugs, too. He found Emory's
+servant," he added, facing the father, "in a Japanese tea house, and
+brought him here to me after the closing scene was set for to-night. You
+may talk with him if you want to. He can tell you how the murder of your
+son was planned, also how the plot to kill Mr. Nestor in the mountains
+was laid--here in these rooms."
+
+Again the old man sank into a chair and buried his face in his hands. It
+was a severe blow to him. He had arrived in San Francisco that day,
+anticipating a pleasant month with his son. And now to find him dead!
+
+"It would be interesting," said Slocum, speaking for the first time
+since the arrests, "to know just how this remarkable boy discovered the
+connection between this flat and the mountain caves."
+
+"The murder brought the clue," Ned replied. "From the first the clue led
+here. And then the key without a stem, the smudge on Emory's finger, the
+typewritten sheets, the machine in the mountains--oh, it was all easy
+enough after the discovery that this man Emory did not know where Albert
+Lemon kept his duplicate key to that desk!
+
+"The case is ended," Ned continued, "and all the parties wanted by the
+law are under arrest, so, if you don't mind, gentlemen, I'll go to bed!"
+
+Jack, Pat, Ernest and Liu now advanced into the room and looked
+smilingly at their leader.
+
+"You can't lose us," Jack said. "If you don't mind, we'll take you back
+to the Rocky Mountains for a little fun with the aeroplane. I guess
+there won't be any bold bad smugglers up there to distract our attention
+for a few weeks."
+
+"And then," Jimmie cut in, "I hope you'll all go back to little old New
+York. I'm hungry and thirsty, and sleepy for a walk down the good old
+Bowery and the wise old White Way!"
+
+The case against Felix Emory was so complete that he pleaded guilty on
+being arraigned in court and was sentenced to the gallows. Chang
+received a long sentence for his connection with the murder, and the
+smugglers and firebugs were sent to prison for ten years each.
+
+The clean-up was so complete that Ned was requested to visit Washington
+and confer with the Secret Service chief regarding other cases.
+
+"But, after all," he said, on leaving Jimmie and the other boys,
+including Ernest and Liu, in New York, "I don't think I want any more
+fighting forest fires assignments in the Secret Service. We'll go back
+some day and look over the ground, but I don't think I'll ever be able
+to get some of those rides in the air out of my mind."

+WOODCRAFT
+for Boy Scouts and Others
+
+By OWEN JONES and MARCUS WOODMAN
+
+With a Message to Boy Scouts by SIR BADEN-POWELL, Founder of the Boy
+Scouts' Movement.
+
+One of the essential requirements of the Boy Scout training is a
+Knowledge of Woodcraft. This necessitates a book embracing all the
+subjects and treating on all the topics that a thorough knowledge of
+Woodcraft implies.
+
+This book thoroughly exhausts the subject. It imparts a comprehensive
+knowledge of woods from fungus growth to the most stately monarch of the
+forest; it treats of the habits and lairs of all the feathered and furry
+inhabitants of the woods. Shows how to trail wild animals; how to
+identify birds and beasts by their tracks, calls, etc. Tells how to
+forecast the weather, and in fact treats on every phase of nature with
+which a Boy Scout or any woodman or lover of nature should be familiar.
+The authorship guarantees its authenticity and reliability.
+Indispensable to "Boy Scouts" and others. Printed from large clear type
+on superior paper.
+
+Embellished With Over 100 Thumb Nail Illustrations Taken From Life.
+
+Bound in Cloth. Stamped with unique and appropriate designs in ink.

+Price, 75c Postpaid

+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or

+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the
+phrase "Project Gutenberg" appears, or with which the phrase "Project
+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3. If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder. Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.
+
+1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form. However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7. Do not charge a fee for access to, viewing, displaying,
+performing, copying or distributing any Project Gutenberg-tm works
+unless you comply with paragraph 1.E.8 or 1.E.9.

+ you already use to calculate your applicable taxes. The fee is
+ owed to the owner of the Project Gutenberg-tm trademark, but he
+ has agreed to donate royalties under this paragraph to the
+ Project Gutenberg Literary Archive Foundation. Royalty payments
+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and
+ sent to the Project Gutenberg Literary Archive Foundation at the
+ address specified in Section 4, "Information about donations to
+ the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+ you in writing (or by e-mail) within 30 days of receipt that s/he
+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+ money paid for a work or a replacement copy, if a defect in the
+ electronic work is discovered and reported to you within 90 days
+ of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+ distribution of Project Gutenberg-tm works.
+
+1.E.9. If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark. Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from. If you
+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5. Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org. Email contact links and up to date contact

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

+<h2><span class='pagenum pncolor'><a id='page_7'></a>7</span><a name='chI' id='chI'></a>CHAPTER I.—A MOUNTAIN MYSTERY.</h2>
+<p>
+On a sizzling hot afternoon near the middle
+of August, in the year nineteen eleven, three
+boys dressed in the khaki uniform of the Boy
+Scouts of America stood on a lofty plateau near
+the British frontier, watching with anxious eyes
+the broken country to the south and west.
+</p>
+<p>
+“Nothing stirring yet!” Jack Bosworth said,
+turning to Pat Mack and Frank Shaw, his companions.
+“Ned and Jimmie may be in trouble
+somewhere. I wish we had waited and traveled
+with them.”
+</p>
+<p>
+“Traveled with them!” repeated Frank
+Shaw. “We couldn’t travel with them. We
+were fired—given the grand bounce—twenty-three
+sign. Ned seemed to want the space in
+the atmosphere we occupied at Missoula. Serve
+<span class='pagenum pncolor'><a id='page_8'></a>8</span>
+them good and right if they do get distributed
+over the scenery.”
+</p>
+<p>
+“Never you mind about Ned Nestor and
+Jimmie McGraw,” Pat Mack put in. “They
+can get along all right if someone isn’t leading
+them by the hand. Suppose we fix up the camp
+and get ready for our eats?”
+</p>
+<p>
+The boys turned away from the lip of the
+caÃąon upon which they had been standing and
+busied themselves putting up shelter tents and
+unpacking provisions and camping tools, as they
+called their blankets and cooking vessels.
+</p>
+<p>
+They had passed the previous night in a sheltered
+valley lower down, sleeping on the ground,
+under the stars, and had breakfasted from the
+scanty stock of eatables carried in their haversacks.
+Early that morning a train of burros had
+landed their outfit at the end of a rough trail some
+distance below, and the boys, with long labor and
+patience, had carried it up to the plateau.
+</p>
+<p>
+The men in charge of the burros had of course
+volunteered to assist in the work of carrying the
+goods to the place selected for the camp, but
+their offers had been declined with thanks, for
+the Boy Scouts were determined that for the
+present no outsider should know the exact location
+of their temporary mountain home.
+<span class='pagenum pncolor'><a id='page_9'></a>9</span>
+</p>
+<p>
+Those who have read the previous books of
+this series<a name="FNanchor_1" id="FNanchor_1"></a><a href="#Footnote_1" class="fnanchor"><sup>[1]</sup></a> will not be at a loss to understand
+why the location of the camp in the Northwest
+was for a time to remain a secret, so far as possible.
+Ned Nestor, for whom those on the plateau
+were now waiting, had, some months before
+that hot August afternoon, enlisted in the
+Secret Service of the United States government.
+</p>
+<p>
+Accompanied by Frank Shaw, Jack Bosworth,
+Jimmie McGraw and others, he had seen
+active diplomatic service during the Mexican
+revolution, had unearthed a plot against the government
+in the Panana Canal Zone, and had rendered
+signal service in the Philippines, where
+he had assisted in preventing an armed revolt
+against the supremacy of the United States government.
+</p>
+<p>
+At the close of his service in the Philippines,
+he had been commissioned to investigate forest
+fire conditions in the Great Northwest. The
+boy had a wonderful native talent for detective
+work, and, besides, it was thought by the officials
+in charge of the matter that a party of Boy
+Scouts, camping and roving about in northern
+Idaho and Montana and in the southern
+<span class='pagenum pncolor'><a id='page_10'></a>10</span>
+sections of British Columbia, would be better able
+to size up the forest fire situation than a party
+of foresters or government secret service men.
+</p>
+<p>
+So Ned and his four chums had sailed away
+from Manila, reached San Francisco in due season,
+and, after receiving further instructions and
+arranging for supplies, had headed for the frontier.
+At Missoula, Montana, he had sent Frank,
+Jack and Pat on ahead, after giving them the
+exact location of the future encampment and
+arranging for the transportation of supplies.
+</p>
+<p>
+From the first there had been some mystery in
+the minds of the three concerning Ned’s strange
+halt at Missoula. They could not understand
+why he had sent them on ahead of him, for he
+usually directed every detail of their journeyings.
+When questioned concerning this innovation,
+Ned had only laughed and told the boys to keep
+out of the jaws of wild animals and not get lost.
+</p>
+<p>
+“I’ll be in camp almost as soon as you are,”
+he had said, “and will take the first mountain
+meal with you.”
+</p>
+<p>
+Yet the boys had reached the vicinity of the
+chosen location on the previous day, and Ned
+had not made his appearance. Naturally the
+boys were more than anxious about the safety
+of their leader.
+<span class='pagenum pncolor'><a id='page_11'></a>11</span>
+</p>
+<p>
+“Did Ned say anything to you while at Missoula,
+about an aeroplane?” Jack asked of Frank
+as they unpacked bacon and corn meal. “You
+know, before we left the Philippines,” he went
+on, slicing the bacon for the coming repast, “the
+officials said we were to have a government aeroplane.
+I was just wondering if the thing would
+get here after we have no use for it.”
+</p>
+<p>
+“He said nothing to me about the arrival of
+the aeroplane,” Frank replied, “but I presume
+he knows when the government air machine will
+be on hand. It may be packed up at Missoula,
+for all we know,” he added, “and Ned may have
+waited there for the purpose of getting it ready
+for flight.”
+</p>
+<p>
+“What the dickens can we do with an aeroplane
+in this wilderness?” demanded Pat, wiping
+the sweat from his face. “We can’t run around
+among the trees with it, can we? Nor yet we
+can’t get gasoline up here to run it with. Anyway,
+I’m no friend to these airships.”
+</p>
+<p>
+“When they travel with upholstered dining
+coaches in connection, and sleeping cars on behind,”
+laughed Jack, “you’ll think they’re all
+to the good. If we can’t chase around among
+the trees in an aeroplane,” he continued, “we
+can sail over the forests and high peaks, can’t
+<span class='pagenum pncolor'><a id='page_12'></a>12</span>
+we? Without something of the sort, it would
+take us about a thousand years to get a look-in
+at this wild country.”
+</p>
+<p>
+“Well,” Pat grumbled, “I only hope we
+won’t get our necks broken falling out of the
+contraption. It may be all right to go up in one
+of the foolish things, but I think I’d rather take
+chances on going over Niagara Falls in a rain-water
+barrel.”
+</p>
+<p>
+“I half believe he will come in the aeroplane,”
+Frank said, shading his eyes with his hand and
+looking out to the south. “He wants to surprise
+us, I take it, and that is why he acted so
+mysteriously about the matter.”
+</p>
+<p>
+“What about Jimmie?” demanded Pat,
+who would take almost any risk on water, but
+who was filled with horror the moment his feet
+left the solid earth. “He can’t bring Jimmie
+along in his pocket, can he? And even if he
+managed to get the little scamp up on the thing,
+some trick would be turned that would land the
+’plane on top of a high tree.”
+</p>
+<p>
+“Two can ride an aeroplane, all right,”
+Frank insisted. “Anyway, quit your knocking.
+Ned knows what he is about, and we’ll wait here
+for him if we have to remain until the Rocky
+Mountains wash down into the Pacific Ocean.”
+<span class='pagenum pncolor'><a id='page_13'></a>13</span>
+</p>
+<p>
+“Suppose we climb up on the shelf above,”
+Jack suggested, “and see if we can find anything
+in the sky that looks like an aeroplane. I really
+think Ned and Jimmie will travel here on the
+air line.”
+</p>
+<p>
+Pat fished a field-glass out of his haversack
+and passed it over to Jack.
+</p>
+<p>
+“You boys go on up,” he said, “and see what
+there is to be seen. I’ll stay here and cook this
+bacon. I could eat a hog on foot right this minute.
+Where did you put those canned beans?”
+</p>
+<p>
+“Never you mind the canned beans,” laughed
+Jack. “It will be time enough to open them
+when you get the bacon fried to a crisp. I see
+our finish if you got one of the bean cans opened.
+Say, but I could eat a peak off the divide!”
+</p>
+<p>
+“Well, the divide is up there, all right,” Pat
+grinned, “go on up and take a bite off it. On
+this side that ridge away up there the rivers run
+into the Pacific ocean. On the other side they
+run into the Atlantic ocean. Split a drop when
+you get on top and send your best wishes to
+both oceans. And don’t you remain away too
+long, either, for this bacon is going to be cooked
+in record-breaking time.”
+</p>
+<p>
+Leaving Pat to prepare the supper, Frank
+and Jack turned their faces upward toward the
+<span class='pagenum pncolor'><a id='page_14'></a>14</span>
+main divide of the Rocky Mountains, 4,000 feet
+above their heads. It was a splendid scene,
+and they enjoyed it to the full. To the north
+the green forests of British Columbia stood
+crinkling under the almost direct rays of the
+August sun, to the east, almost over their heads,
+stood the backbone of the continent of North
+America, to the south stretched the broken land
+of Montana, while to the west lay the valleys
+and ridges of Idaho, Montana, and Washington
+beyond which pulsed the mighty swells of the
+Pacific.
+</p>
+<p>
+Immediately to the north of the position
+occupied by the camp, and within a mile of
+the international boundary line, Kintla lake
+lay like a mirror in the lap of the mountains,
+reflecting peaks and silent groves in its clear
+waters. From the lake, ten miles in length by
+half that in width, an outlet flowed westward
+into the North Branch of the Flathead river.
+</p>
+<p>
+The level plateau where the camp had been
+pitched was not far from two acres in extent,
+with the bulk of the mountain to the east, a drop
+of a thousand feet to the south, and steep but
+negotiable inclines to the west and north. The
+lake was 300 feet below the level of the plateau,
+which was about 3,000 feet above the sea level
+<span class='pagenum pncolor'><a id='page_15'></a>15</span>
+and 4,000 feet below the summit of the divide
+at that point in the long range of mountains.
+</p>
+<p>
+There were peaks to the north and south
+which showed eternal snow and ice, but there
+was a lowering of the shoulder of the great chain
+directly to the east, so there was no snow in sight
+there. There were forest trees low down in the
+caÃąon to the south, and on the slopes to the
+west and north, but the plateau and the sharp
+rise toward the summit were bare.
+</p>
+<p>
+While Pat sliced his bacon and mixed corn-meal,
+soda, salt and water to make hoecakes,
+to be fried in bacon grease, Frank and Jack
+wormed their way up the face of the mountain,
+toward a shelf of rock some hundred feet above
+the plateau. It was hard climbing, but the lads
+persisted, and soon gained the elevation they
+sought, from which it was hoped to gain a fine
+view of the country toward Missoula.
+</p>
+<p>
+“Good thing we don’t want to go any farther,”
+Frank exclaimed, throwing himself down
+on the ledge and wiping his streaming face.
+“We couldn’t scale the wall ahead with a ladder.
+Now,” he went on, “look out there to the south
+and see if there’s an aeroplane in sight.”
+</p>
+<p>
+Jack brought out the field-glass and looked
+long and anxiously, but there was no sign of a
+man-made bird in the clear sky.
+<span class='pagenum pncolor'><a id='page_16'></a>16</span>
+</p>
+<p>
+“I don’t believe, after all, that he’ll come in
+an aeroplane,” the boy said, directly. “Suppose
+he took a notion to get a motor boat and
+run up the north branch of the Flathead river,
+and so on into Kintla lake, down there? How
+long would it take him to make the trip?”
+</p>
+<p>
+“About ten thousand years,” was Frank’s
+reply. “He never could get up the north branch.
+There’s too many waterfalls. Why, man, the
+stream descends several thousand feet before it
+gets to sea level.”
+</p>
+<p>
+“Anyway,” Jack replied, “if you’ll get out
+of my way I’ll take a look at the lake through
+the glass.”
+</p>
+<p>
+“You’ll probably see him come sailing up
+the slope in a battleship,” Frank said, in a sarcastic
+tone.
+</p>
+<p>
+Jack, without speaking, turned his glass to
+the north and gazed long and anxiously over
+the lake. Presently Frank saw him give a start
+of surprise and lean forward, as if to get a closer
+view of some object which had come into the
+field of the lens.
+</p>
+<p>
+“What is it?” he asked.
+</p>
+<p>
+Jack passed him the glass with no word of
+explanation, and the boy hastily swept the
+shores of the mountain lake.
+<span class='pagenum pncolor'><a id='page_17'></a>17</span>
+</p>
+<p>
+“I don’t see any motor boat,” he said, directly.
+</p>
+<p>
+“Well, what do you see?” Jack asked, expectantly.
+</p>
+<p>
+“For one thing,” Frank replied, “the smoke
+of a campfire.”
+</p>
+<p>
+“I saw that, too,” Jack said, “and didn’t
+know what to make of it. Also, I saw a rowboat
+sneaking around that green point to the east.”
+</p>
+<p>
+“That is what is puzzling me,” Frank replied.
+“Years ago there was a Blackfoot reservation
+just over the divide, and a Flathead Indian
+reservation down by Flathead lake, to the
+south, but I had no idea the Indians were still
+about. Still, the people you saw were probably
+Indians. Suppose we go down there and look
+the matter up. We’ve got to have some sort of
+a yarn to tell Pat when we get back to camp.”
+</p>
+<p>
+The two boys scrambled down almost vertical
+surfaces, edged along narrow ledges, slid down
+easier inclines, and finally came to the rim of
+beach about the lake. There, at the eastern
+end of the pretty body of water, they came upon
+the still glowing embers of a fire.
+</p>
+<p>
+Close to the spot where the remains of the
+fire glimmered in the hot air, they saw the mouth
+of a cavern which seemed to tunnel under the
+<span class='pagenum pncolor'><a id='page_18'></a>18</span>
+body of the mountain to the east. There were
+numerous tracks about the fire, and some of
+them led to the entrance to the cavern.
+</p>
+<p>
+“Whoever built this fire,” Jack exclaimed,
+“wore big shoes, so it wasn’t Indians. No,
+wait!” he added, in a moment, “there are tracks
+here which show no heel marks. What do you
+make of that?”
+</p>
+<p>
+“Must be moccasins,” Frank said. “The
+Indians may still be in the woods about here.”
+</p>
+<p>
+“I’m going into the cavern to see what’s
+stirring there,” Jack said, “and before I go I’ll
+have a look at my artillery.”
+</p>
+<p>
+The boy looked his revolver over, and before
+Frank could utter a warning, he darted away
+into the gloom of the cave. Frank did not follow
+him, but turned in the direction of the point
+where the boat had disappeared.
+</p>
+<p>
+A dozen yards on his way he stopped and
+listened. A voice, sounding like that of a person
+in a deep well, reached his ears, and he
+turned back.
+</p>
+<p>
+He gained the mouth of the cavern in half a
+minute and plunged inside. It was dark a dozen
+feet from the entrance, but he struck a match
+and moved on, finally coming to a smooth wall
+which appeared to shut off farther progress.
+<span class='pagenum pncolor'><a id='page_19'></a>19</span>
+</p>
+<p>
+When he turned about and faced the opening
+every object between where he stood and the
+mouth stood revealed against the bright sunshine
+outside. There were a few loose rocks, a
+rude bench, a small goods box, and nothing else.
+Jack was nowhere in eight.
+</p>
+<p>
+He examined the walls of the cavern but discovered
+no lateral passages. He called out to
+his chum, but received no response. Where was
+Jack? If he had left the cavern he would have
+been seen. It was a perplexing mystery, and
+the boy sat down on the box and listened for a
+repetition of the sounds he had heard.
+</p>
+<p>
+For a moment no sounds came, then a voice,
+seemingly coming out of the solid wall behind
+him reached his ears. He could distinguish no
+words for a time, and then it seemed that he was
+being called by name.
+</p>
+<p>
+He called to Jack again and again, but received
+no answer. Jack was evidently there
+somewhere, but where? The smooth walls gave
+no indication of any hidden openings, and there
+was in view no crevice through which a voice
+behind the walls might penetrate. It seemed
+either a silly joke or an impenetrable mystery.

+<p>
+Frank left the cavern in a moment and
+walked along the beach toward the campfire.
+His thought was to gather embers and fresh fuel
+and build up a blaze at the end of the cave which
+would reveal every inch of the interior. He was
+certain that Jack had not left the place, and decided
+that he had fallen into some hidden opening
+which had escaped his own investigation.
+</p>
+<p>
+As he bent over the remains of the fire he
+heard a rattle of small stones, and, looking up,
+saw Pat coming down the declivity from the plateau
+where the tents had been set up. The incline
+was steep, and at times Pat was rolling
+rather than walking. He was in his shirt sleeves
+and bareheaded. At last his red head pitched
+toward the lake like a meteor in downward flight.
+</p>
+<p>
+Frank rushed forward and caught him as he
+struck the beach, thus saving him from an impromptu
+bath. Pat struggled to his feet in an
+instant, rubbed his legs and arms to see if any
+bones had been broken, and then turned his head
+and looked up the incline.
+<span class='pagenum pncolor'><a id='page_21'></a>21</span>
+</p>
+<p>
+“Talk about shooting the chutes!” he exclaimed.
+“I wonder what time I made coming
+down?”
+</p>
+<p>
+“Sure you’re not hurt?” asked Frank anxiously.
+</p>
+<p>
+“Every inch of my body has three bruises,
+one on top of the other,” Pat replied, “but I
+guess I’m able to walk. Say, but that was a
+roller-coaster glide!”
+</p>
+<p>
+“Why did you try such a foolish caper?”
+asked Frank.
+</p>
+<p>
+“Why, I saw you boys here,” was the reply,
+“and started down. You know the rest, as the
+yellow-covered books say. What you boys
+doing here, wasting your time, with the bacon
+burning to a crisp?”
+</p>
+<p>
+“We came here to investigate,” was the reply,
+“and Jack went into the cavern, and vanished—just
+vapored into thin air. I’m going to
+build a fire in there and see if I can’t condense
+him!”
+</p>
+<p>
+“Well,” Pat said, listening, “he may have
+vanished physically, but his voice appears to be
+on deck yet.”
+</p>
+<p>
+Three sharp calls came from the cavern, and
+both boys dashed inside. There was no doubt
+now that Jack’s voice, at least, had condensed,
+<span class='pagenum pncolor'><a id='page_22'></a>22</span>
+for the shouts coming from the back of the cavern
+were both hearty and imperative.
+</p>
+<p>
+“Hi, there!” Jack called. “Pry this stone
+out of the doorway!”
+</p>
+<p>
+“Where are you?” demanded Pat. “Which
+one of the walls do you want us to push in?
+You’re a nice chump, getting in a scrape like
+this!” he added, with a laugh which must have
+been exasperating to the unseen boy.
+</p>
+<p>
+“You’ll find a crevice where the back of the
+cave joins the south wall,” Jack said, his voice
+coming faintly to the ears of his chums. “Put
+your fingers in and pull. The blooming door
+opens outward. Hurry! It’s stifling in here!”
+</p>
+<p>
+After burning nearly all the matches they
+had in their pockets, and scorching their fingers
+on the short sticks, Pat and Frank discovered
+the crevice spoken of and inserted the ends of
+their fingers.
+</p>
+<p>
+“Pull!” yelled Jack. “Pull, you loafers! It
+is moving!”
+</p>
+<p>
+In a moment the south half of the back wall
+swung out so suddenly that both boys were
+thrown from their feet and Jack, who had been
+pushing with his whole strength, came tumbling
+on top of them as they lay on the floor of the
+cavern.
+<span class='pagenum pncolor'><a id='page_23'></a>23</span>
+</p>
+<p>
+“What sort of a combination is this, anyway?”
+demanded Pat, struggling to his feet.
+“If I get any more bumps to-day I’ll be taking
+something that belongs to some one else. I’ve
+had my share.”
+</p>
+<p>
+Frank sprang to the opening as soon as he
+could disentangle himself from the collection of
+arms and legs and looked in. All was dark and
+still inside, and a gust of dead air struck him in
+the face. Pat, leaning over his shoulder, laid a
+hand on the rock which had opened so strangely,
+and the next instant it closed softly, sliding into
+the opening like a door operated by well-oiled
+machinery.
+</p>
+<p>
+“Now you’ve done it!” Frank exclaimed,
+disgustedly, as Pat threw himself against the
+stone in a vain effort to force it open again.
+</p>
+<p>
+“No harm done,” Jack exclaimed. “There’s
+only a stinking cavern in there. Wow! I can
+feel snakes and lizzards crawling on me now!
+Come! Let us get into the open air. Stifles
+like a grave in here.”
+</p>
+<p>
+The boys hastened outside and stood meditatively
+before the shining waters of the lake,
+each one trying to think clearly concerning what
+had taken place. They believed themselves—or
+had believed, rather—miles away from any trace
+<span class='pagenum pncolor'><a id='page_24'></a>24</span>
+of civilization, and yet here was a practical door
+of rock at the end of a cave almost under the
+great divide.
+</p>
+<p>
+“We’ve found something,” Frank said, at
+length. “That thing in there never happened.
+Human hands fashioned that door for some secret
+purpose. And it wasn’t Indians, either.”
+</p>
+<p>
+“I guess we’ve run up against a band of train
+robbers,” suggested Jack, with a grin.
+</p>
+<p>
+“Probably the entrance to some deserted
+mine,” Pat put in. “This region has been
+searched for gold for fifty years. I’ve heard of
+mines being concealed by moving stones.”
+</p>
+<p>
+“Well,” Frank said, after a short silence,
+during which all listened for some indication of
+the immediate presence of the men who had been
+seen to row around the green point a short time
+before, “whatever the game is, we’ve got to remove
+every trace of our visit. When they come
+back they probably won’t notice the tracks we
+have made, for there were plenty about before
+we came here, but we must gather up all the
+match-ends we left in there and leave the door
+as we found it.”
+</p>
+<p>
+“I found it open and walked in,” Jack said,
+“and then it closed. Whew! I felt like I was
+being shut up in a tomb!”
+<span class='pagenum pncolor'><a id='page_25'></a>25</span>
+</p>
+<p>
+“How large a place is it in there?” asked Pat.
+</p>
+<p>
+“Don’t know,” was the reply. “I had no
+matches with me, and so could not see a thing.”
+</p>
+<p>
+“Then we won’t have to open the door again
+to clean up any muss,” Frank said, moving toward
+the entrance to the cavern.
+</p>
+<p>
+“I wouldn’t go in again for a thousand dollars,”
+Jack cried. “If you leave it to me, the
+place is haunted. I heard groans in there.”
+</p>
+<p>
+Frank paused at the entrance and turned
+back. His matches were about gone, and so
+he took a burning stick from the fire, added two
+dry faggots to it, waited until the three burst
+into flame, and then entered the cave.
+</p>
+<p>
+To gather up the half-burned matches which
+had been scattered over the floor was the work
+of only a moment.
+</p>
+<p>
+“Now you’ll have to open the door, if you
+leave it as I found it,” Jack said, looking in from
+the mouth. “Pat will help you.”
+</p>
+<p>
+“Come on in, both of you,” Frank directed.
+</p>
+<p>
+“Not me!” cried Jack. “I hear bones rattling!”
+</p>
+<p>
+The boys thought he was joking at first, but it
+soon appeared that he was in sober earnest, so
+Pat and Frank, by exerting their entire strength,
+managed to open the door without his assistance.
+<span class='pagenum pncolor'><a id='page_26'></a>26</span>
+</p>
+<p>
+“You’re afraid of the dark!” Pat taunted,
+as the boys gathered around the fire again.
+</p>
+<p>
+“I’m not half as afraid of the dark as you are
+of an aeroplane,” Jack replied. “If I ever see
+you going up in a ’plane, I’ll go in there alone.”
+</p>
+<p>
+“Don’t you ever forget that,” Pat grinned.
+</p>
+<p>
+“Oh, I’ll be game, all right,” was the reply.
+</p>
+<p>
+Before leaving the beach for the camp the
+boys walked to the point around which the boat
+had gone and scanned the lake and its shores
+through the field-glass. There was no sign of
+life anywhere, except where the birds swung
+from forest limbs back from the rim of the lake
+and called each other through the sultry air.
+</p>
+<p>
+Reaching the camp after a weary climb, they
+did full justice to the meal which Pat had prepared,
+though the bacon and the hoecakes were
+stone cold, or at least as cold as anything could
+be in that glare of sunlight. Then, the dishes
+washed and the beds prepared for the night,
+they sat down to watch the lake and the sky to
+the south, for it was now the general belief that
+Ned would make his appearance with the aeroplane
+which had been promised by the government
+officials.
+</p>
+<p>
+The point they had last visited, as well as
+the location of the fire, was in full view of the
+<span class='pagenum pncolor'><a id='page_27'></a>27</span>
+plateau, so the boys made no efforts to conceal
+their presence there. The men who had been
+observed in the boat must have noted their
+presence on the plateau before taking their leave.
+Perhaps, they reasoned, they had taken their
+departure because of this invasion.
+</p>
+<p>
+The sun sank lower and lower in the sky,
+turning the plateau and the smooth waters of the
+lake to gold, still there were no signs of Ned, no
+indications of the return of the boat to the place
+from which it had been launched. Half an hour
+after dark, Frank, who was looking through the
+field-glass, caught sight of light in the south
+which did not appear to come from any star.
+</p>
+<p>
+“Here he comes!” he cried. “That’s an
+aeroplane, all right!”
+</p>
+<p>
+As the light drew nearer, traveling rapidly,
+the sharp explosions of the gasoline engine became
+audible. Then a light flickered over the
+upper plane, passed off, and swept the white
+surface again.
+</p>
+<p>
+“How does he make that?” demanded Pat.
+“Looks like a great question mark.”
+</p>
+<p>
+“That’s what it is,” Frank exclaimed.
+“Now, what does he mean by it?”
+</p>
+<h2><span class='pagenum pncolor'><a id='page_28'></a>28</span><a name='chIII' id='chIII'></a>Chapter III.—JUST A TYPEWRITER RIBBON.</h2>
+<p>
+“I don’t understand what question he is
+asking,” Jack said, “but I know how he makes
+the signal. He has an electric flashlight, and he
+tips the plane—the upper plane—forward, like he
+was plunging to the earth, and writes the interrogation
+mark on the under side with the flame
+of the flashlight. See? Then it shines through
+the canvas and we read it! Great idea!”
+</p>
+<p>
+“That must be the way of it,” Frank said,
+“but what does he want? And how does he expect
+us to answer?”
+</p>
+<p>
+“If I was up there in the dark on a contraption
+like that,” Pat said, “I’d be asking how I
+was going to find a landing place.”
+</p>
+<p>
+“Sure!” Frank cried. “Ned wants to know
+where we are, and whether it is safe for him to
+make a landing. Dunderheads! Why didn’t
+we think of that before? He is passing now,
+and may not come back again.”
+</p>
+<p>
+The light flashed by at swift speed, whirled,
+ascended several hundred feet, and came over the
+<span class='pagenum pncolor'><a id='page_29'></a>29</span>
+plateau, repeating the signal. Then it settled
+down into a steady circling of the camp.
+</p>
+<p>
+“He knows where we are, all right,” Pat said.
+“What he wants to know is if it is safe for him
+to make a landing. If I ever go up in one of
+those things I’ll drag a rope so I can climb down
+it.”
+</p>
+<p>
+“I’ll tell him what he wants to know,” Frank
+said, “if you’ll get me a long stick on fire most of
+its length.”
+</p>
+<p>
+“Wigwag?” asked Jack.
+</p>
+<p>
+“Sure!” was the reply. “Now,” Frank
+continued, “build four fires, one on each edge of
+the plateau. That will show him how large the
+place is. Then I’ll take the flaming stick and
+wigwag o.k. Ned’ll understand that.”
+</p>
+<p>
+Pat watched the wigwag signal with interest.
+</p>
+<p>
+“I saw foolish signs like those in the Philippines,”
+he said, with a grin. “The natives use
+them to talk treason to each other. I’ve heard
+that the same method is used by the East Indians
+who talk from one mountain top to another
+faster than words on a wire. How does he make
+the o.k. signal?”
+</p>
+<p>
+“O is one left, followed by one right,” Jack
+replied, “and k is left, right, left, right. You
+won’t think the signs are foolish when you see
+<span class='pagenum pncolor'><a id='page_30'></a>30</span>
+how quickly Ned reads them. See! He’s
+shooting away now.”
+</p>
+<p>
+“Perhaps he thinks the signals are being
+made by savages,” Pat said.
+</p>
+<p>
+The aeroplane darted off to the west for half
+a minute, then whirled and came back. The
+boys could not see the great ’plane distinctly,
+but the lights which burned on the front were
+bright and clear, so they saw that the ’plane was
+sweeping toward the earth as it advanced in
+their direction.
+</p>
+<p>
+“I don’t believe many professionals would
+care to make a landing like this,” Frank said,
+as the machine dipped and slid to the ground,
+exactly in the center of the plateau.
+</p>
+<p>
+“Hello, Ned!” he yelled, as the aeroplane
+rolled over the smooth surface for an instant and
+stopped.
+</p>
+<p>
+In a second the three boys were gathered
+about the machine, pulling at the hands and feet
+of the daring riders. Jimmie McGraw bounded
+to the ground as soon as he could cast off the lines
+which had held him to his quivering seat.
+</p>
+<p>
+“Say,” he cried, “you got a fire here? I’m
+most froze.”
+</p>
+<p>
+Indeed the little fellow’s teeth were chattering.
+<span class='pagenum pncolor'><a id='page_31'></a>31</span>
+</p>
+<p>
+“Cold?” echoed Pat. “We’re melting down
+here. You’re scared, that’s what’s the matter
+with you. You’re scared stiff.”
+</p>
+<p>
+Jimmie made a run for the speaker but
+brought up at the fire where the supper had been
+cooked.
+</p>
+<p>
+“Here’s comfort!” he cried, extending his
+hands out over what was left of the small blaze.
+“The next time you get me up in the air I don’t
+go! I’ve been freezing for an hour.”
+</p>
+<p>
+In the meantime Ned Nestor was caring for
+the aeroplane, looking after the delicate machinery
+and covering it carefully with a huge oil-cloth.
+Pat stood watching the work with a grin
+on his face.
+</p>
+<p>
+“Are you thinking of giving me a ride in that
+thing?” he asked.
+</p>
+<p>
+“Not to-night!” laughed Ned.
+</p>
+<p>
+“Well, when you get ready for me to ride the
+air,” Pat said, “just tell me the night before, and
+I’ll shoo myself into the hills. If I’m going to
+fall off anything, I’ll take the drop from something
+solid, like a mountain top.”
+</p>
+<p>
+“No danger at all, when you know how to
+operate the machine,” Ned replied. “There’s
+danger in running anything if you don’t know
+how, even a sewing machine.”
+<span class='pagenum pncolor'><a id='page_32'></a>32</span>
+</p>
+<p>
+“Where did you pick it up?” asked Frank.
+</p>
+<p>
+“He didn’t pick it up at all,” interposed Pat.
+“It picked him up.”
+</p>
+<p>
+“I found it at Missoula,” was the reply, “all
+packed and stored away in a freight warehouse.
+I had to get it out at night, and so lost time.
+The people would have kept me there until now
+giving exhibitions if I had shown up during the
+day.”
+</p>
+<p>
+“But you did leave there in the daytime,”
+urged Jack. “You were never in the air since
+last night.”
+</p>
+<p>
+“We left early this morning,” was the reply,
+“and I was well up in the sky before many of the
+people saw me.”
+</p>
+<p>
+“I never knew you could run one,” Frank
+said.
+</p>
+<p>
+“Oh, I had some instructions from the
+Wrights,” was the modest reply, “and, besides,
+there was an expert at Missoula who helped me
+get the machine together and contributed a few
+parting instructions.”
+</p>
+<p>
+“Then you’ve been in the air all day?”
+asked Pat.
+</p>
+<p>
+“No, we stopped several times, of course,
+once on the right of way of the Great Northern
+railroad and filled our gasoline tanks,” was the
+<span class='pagenum pncolor'><a id='page_33'></a>33</span>
+reply, “and rested there a few hours. Jimmie
+had to eat there, of course!”
+</p>
+<p>
+“Eat!” came the boy’s voice from the fire.
+“If I ever get a bite at food again it will drop
+down into the toes of me shoes! Here!” he
+shouted, as Pat produced a can of pork and beans
+and started to open it. “You needn’t mind
+opening that! I’ll just swallow it as it is.”
+</p>
+<p>
+“Bright boy!” laughed Pat, handing him a
+liberal supply of beans and fried bacon. “Now
+fill up on that and then loosen up on your impressions
+of the sky.”
+</p>
+<p>
+“I thought I’d make an impression on the
+earth before I got through,” Jimmie mumbled, his
+mouth full of beans. “We went up so far that the
+mountains looked like ant hills, didn’t we, Ned?”
+</p>
+<p>
+“About 7,000 feet,” was the reply. “You
+see,” he added, turning to Frank, “I wanted to
+size up the situation before I landed. If there
+is anybody in this upturned country at all, our
+presence here is known. The aeroplane’s chatter
+took good care of that. And, besides, our
+landing in the night, with the lights going, gave
+unmistakable evidence of something stirring.”
+</p>
+<p>
+“I should say so,” Frank agreed.
+</p>
+<p>
+“And so,” Ned went on, “I wanted to learn
+if there were people about here, so I might visit
+<span class='pagenum pncolor'><a id='page_34'></a>34</span>
+them in the morning and put up the bluff of
+Boy Scouts playing with an aeroplane in the
+woods. We can’t attempt anything in the mysterious
+line,” he went on. “We’ve got to be
+entirely frank about everything except the business
+we are here on.”
+</p>
+<p>
+“Well,” Frank said, “we found people here
+to-day and called on them.”
+</p>
+<p>
+“What sort of people?”
+</p>
+<p>
+“Well, they seemed to have good broad
+backs,” laughed Frank.
+</p>
+<p>
+“They ran away from you?” asked Ned, in
+surprise. “I should think they would have
+proved inquisitive. Where were they?”
+</p>
+<p>
+“Down by Kintla lake.”
+</p>
+<p>
+“Indians?” asked Ned.
+</p>
+<p>
+Then Frank told the story of the visit to
+the shore of the lake and the cavern, taking
+good care to describe the surroundings as closely
+as possible. Ned laughed when the boy came
+to Jack’s adventure in the hidden chamber.
+</p>
+<p>
+“I say it is some deserted mine,” Pat declared,
+when Frank had concluded the recital.
+“What else could it be?”
+</p>
+<p>
+“Robber’s nest!” suggested Jack.
+</p>
+<p>
+Ned remained silent for a moment and then
+abruptly asked:
+<span class='pagenum pncolor'><a id='page_35'></a>35</span>
+</p>
+<p>
+“What kind of footwear made those heelless
+prints?”
+</p>
+<p>
+“You may search me!” Jack cut in.
+</p>
+<p>
+“Must have been Indian moccasins,” Frank
+observed.
+</p>
+<p>
+Jimmie, who had been standing by the small
+fire, listening to the talk, now advanced to the
+little circle about the machine and uttered one
+word: “Chinks!”
+</p>
+<p>
+“It is always Chinks with Jimmie,” grinned
+Frank. “When there is a cyclone in New York
+the Chinks are to blame for it, if you leave it to
+him.”
+</p>
+<p>
+“What would Chinks be doing up here?”
+demanded Pat.
+</p>
+<p>
+“Don’t they get gold by washing it out?”
+asked Jack, with a nudge at Jimmie’s side.
+“Perhaps they’re going to start a laundry!”
+</p>
+<p>
+While this chaff was in progress Ned stood
+looking thoughtfully in the direction of the lake.
+Not a word did he say regarding the sudden and
+brief communication Jimmie had presented.
+</p>
+<p>
+“Any forest fires in sight?” asked Pat, finally
+breaking the silence.
+</p>
+<p>
+“Not one,” Jimmie answered. “I would have
+dropped into one if it had come my way. It
+was fierce up there!”
+<span class='pagenum pncolor'><a id='page_36'></a>36</span>
+</p>
+<p>
+“It is rather cool when you get up a couple
+of miles,” Ned laughed, “and Jimmie wouldn’t
+listen to reason regarding his clothes. To-morrow
+I’ll give one of you boys a ride, and you may
+see for yourself.”
+</p>
+<p>
+“Not me!” Pat exclaimed. “I’ll stay below
+and help pick up the pieces.”
+</p>
+<p>
+“I should like to go,” Frank said. “We
+may find the people we saw in the rowboat.
+When we become acquainted with them we may
+be able to learn something about that cavern.”
+</p>
+<p>
+“I would advise remaining silent about the
+cavern,” Ned said. “It may be used for some
+criminal purpose, and we must not admit that
+we know of its existence. We are just carefree
+lads, here for an outing, remember,” he added,
+with a laugh, “and we are due to make friends
+with everybody we come across.”
+</p>
+<p>
+“But you made us lug all this camping outfit
+up here,” complained Jack, “so the men who
+steered the burros up the hills wouldn’t know
+where we camped. What about that?”
+</p>
+<p>
+“I thought it best to cut off all communication
+with the people below,” explained Ned.
+“It may be that the purpose of our visit here is
+suspected. In that case some one from below
+might want to find us—for no good purpose.
+<span class='pagenum pncolor'><a id='page_37'></a>37</span>
+So we’ll keep out of sight of the people in the
+towns, unless they see our aeroplane, and cultivate
+the acquaintance of the natives—if there
+are any.”
+</p>
+<p>
+“How about gasoline and provisions?” asked
+Pat.
+</p>
+<p>
+“I have plenty of gasoline stored on the right
+of way of the Great Northern railroad,” Ned
+replied, “enough to last us a month. It was
+piped into a hidden tank from an oil car by a
+train crew now out of the state. We are to get
+provisions at the same place, if we need more,
+for Uncle Sam fixed all the details for us. All we
+have to do is to find the fellows who are setting
+forest fires and bring them to punishment.”
+</p>
+<p>
+“We ought to locate every little smudge,
+with that aeroplane,” Frank suggested.
+</p>
+<p>
+“That is my idea,” Ned replied. “Have
+you been keeping a good lookout on the lake
+since you left it?” he added, turning to Pat.
+</p>
+<p>
+“Some one of us has had eyes on it every
+minute,” was the satisfactory reply. “No one
+has returned, I’m sure.”
+</p>
+<p>
+“You’re not thinking of going there to-night,
+are you?” asked Jack, with a slight shiver. “I
+wouldn’t go in there again, even in broad daylight,
+for a million dollars!”
+<span class='pagenum pncolor'><a id='page_38'></a>38</span>
+</p>
+<p>
+“Pat is afraid of the sky, and Jack is afraid
+of the bowels of the earth!” laughed Frank.
+“We’ll have to tuck them both in bed before we
+can accomplish anything.”
+</p>
+<p>
+“You may all go to bed but one,” Ned said,
+looking about the group, his eyes finally resting
+with a significant look on Frank’s excited face.
+“I want to look through that cavern before anything
+is taken out of it.”
+</p>
+<p>
+Frank, knowing the meaning of the look he
+had received, went to his little tent for his revolver
+and his electric searchlight and was soon
+ready for the expedition. Jimmie looked sulky
+for a moment at being left out of the game, then
+his face brightened and he crawled into the tent
+that had been prepared for Nestor and himself
+and burst into a fit of laughter.
+</p>
+<p>
+“I’ll show ’em!” he said, stuffing the blanket
+into his mouth to suppress the sound of his merriment.
+“I’ll teach ’em to put me in the discard.”
+</p>
+<p>
+“Any wild animals up here?” asked Ned, as
+the two started away down the steep declivity.
+</p>
+<p>
+“Two Black Bears and three Wolves!” called
+Jimmie, from his tent.
+</p>
+<p>
+This was a reference to the Boy Scout Patrols
+to which the boys belonged. Frank and Jack
+<span class='pagenum pncolor'><a id='page_39'></a>39</span>
+were members of the famous Black Bear Patrol
+of New York City, while Ned, Pat and Jimmie
+were members of the Wolf Patrol.
+</p>
+<p>
+As the lad spoke Frank and Jack broke into
+growls which might well have come from the
+throat of the grizzliest grizzly in the Rocky
+Mountains, while Pat sent forth a wolf howl,
+which might well have been a signal to the pack.
+</p>
+<p>
+“You may meet the real thing out here,”
+warned Ned, turning back to look over the plateau,
+now shining in the light of a half-moon.
+“There are both bears and wolves in this region.
+When you meet them, don’t wait for Boy Scout
+signs!”
+</p>
+<p>
+“Oh, we’ll initiate ’em, all right,” Jimmie
+called from the tent, and Ned and Frank moved
+on down the declivity toward the lake.
+</p>
+<p>
+It was still early evening, and the moon was
+low down in the east, so the valley where the
+lake lay was not touched by its light. Indeed,
+the plateau where the boys were would have
+been in the shadow of the mountain only for the
+dropping of the shoulder of the divide.
+</p>
+<p>
+In half an hour the two boys, after several
+slides which were anything but pleasant, gained
+the beach. The campfire was now dead, and
+<span class='pagenum pncolor'><a id='page_40'></a>40</span>
+the locality was still save for the voice of a night
+bird and the occasional splash of a leaping fish.
+The mouth of the cavern loomed like a dark
+patch on the lower bulk of the mountain.
+</p>
+<p>
+Making as little noise as possible, Ned and
+Frank crept into the cavern, advancing by the
+sense of feeling until they came to the very end
+before turning on one of the electric flashlights.
+The round eye of the flame showed a long, narrow,
+tunnel-like tube running directly east, under
+the mountain. The door of rock was as the boys
+had left it earlier in the day.
+</p>
+<p>
+Ned examined that portion of the rock which
+had swung out into the first chamber with considerable
+care, as the story of the swinging stone
+had interested him greatly. All along the top,
+up to the center, he found the checks of a stone-chisel.
+Exactly in the middle an elevation of an
+inch fitted into a round cavity in the upper rock.
+At the bottom the same conditions were discovered.
+</p>
+<p>
+“Rather a clever job,” Ned said, “but I
+don’t see how it was ever done.”
+</p>
+<p>
+“This door,” Frank said, “is not exactly like
+the remainder of the wall in grain, so it must
+have been brought here from some other locality.
+<span class='pagenum pncolor'><a id='page_41'></a>41</span>
+Of course there was a hole between these two
+chambers, or the second one would never have
+been found. It would be easy enough to fit the
+stone door in by grooving out from the lower
+cavity and sliding the under pivot in.”
+</p>
+<p>
+“Sure,” Ned replied, getting down to examine
+the lower part of the door more closely,
+“and that is just what was done. Then the
+groove was filled with concrete. Pretty classy
+work here!”
+</p>
+<p>
+“And now the question is this,” Frank went
+on, “what was the door fitted for? Why did
+the men who found the cave desire privacy? Is
+there gold in there? Have the men who have
+been setting fire to the forests established a home
+here? Is this the hiding place of a band of outlaws?
+You see there are lots of questions to ask
+about the two caverns,” Frank added, with an
+uneasy laugh.
+</p>
+<p>
+Ned closed the stone door and turned on
+both electric flashlights, making the place light
+as day where they stood. The inner cavern was
+as bare as the outer one save for dead leaves and
+grass which lay in heaps on the stone floor, and
+for half a dozen rough benches which were piled
+in one corner. At the farther end hung a gaudy
+<span class='pagenum pncolor'><a id='page_42'></a>42</span>
+curtain, once handsome, but now sadly spotted
+with mildew because of dampness.
+</p>
+<p>
+“Here’s the inner chamber,” laughed Frank,
+drawing the curtain aside. “And it looks like
+it was the private office of the bunch, too,” he
+added, as he turned the light about the walls.
+</p>
+<p>
+There was a desk in the third cavern, a swivel
+chair, a small case of books, and a rusty safe,
+which looked as though it had not been opened
+for years. A current of fresh air came from the
+rear, and a small opening was soon discovered.
+</p>
+<p>
+“That doubtless leads to some caÃąon not far
+away,” Ned said. “Makes a pretty decent
+place of it, eh?”
+</p>
+<p>
+“Good enough for any person to hide in,”
+replied Frank. “Now,” he added, “tell me
+what you think of it. Who cut this cavern, and
+who brought the furniture here? I’ll admit that
+my thinker is not working.”
+</p>
+<p>
+“Nature made the caverns,” Ned replied.
+“There is what geologists call a fault in the rock
+here. Owing to volcanic action, doubtless, the
+strata shifted, probably thousands of years ago,
+and when the seam appeared the broken pieces
+fell apart. These chambers show the width of
+the seam. There undoubtedly was a great earthquake
+<span class='pagenum pncolor'><a id='page_43'></a>43</span>
+at the time, and the lake below might
+have been dredged out at that time.”
+</p>
+<p>
+“Of course,” Frank said, “I might have
+known that! Now, here’s another question:
+How far does this seam extend under the Rocky
+Mountains? If it passes beyond these three
+chambers, why not make a fourth room for ourselves
+so as to be on the spot when the men who
+make headquarters of the place come back?”
+</p>
+<p>
+“That may be a good thing to do,” Ned admitted,
+“but, still, I would not like to be the
+one to lie in wait here. Suppose we try to learn
+something of the character of the people who
+come here? They seem to sleep on dry leaves
+and eat off benches. Rather tough bunch, I
+take it. Perhaps we have struck Uncle Sam’s
+enemies the first thing!”
+</p>
+<p>
+Keeping their lights on, and working as silently
+as possible, always with an eye to the outer
+cavern, the boys made a careful search of the
+inner chamber. The desk was not fastened, and
+a cupboard afterward discovered in a niche was
+open also. There were dishes in the cupboard
+and writing materials in the desk.
+</p>
+<p>
+At the very bottom of the desk drawer Ned
+came upon a surprise.
+<span class='pagenum pncolor'><a id='page_44'></a>44</span>
+</p>
+<p>
+“Not so tough as I supposed,” he said, turning
+to Frank. “Here’s a typewriter ribbon.
+The sort of people who set fire to forests and hold
+up trains are hardly in the typewriter class.
+What do you make of it?”
+</p>
+<p>
+“Well,” Frank said, with a chuckle, “if
+you’ll tell me what the inhabitants of this place
+want of typewriter ribbons I’ll tell you why they
+bring great tins of opium here. It seems that
+we have struck something more important than
+forest fires.”
+</p>
+<h2><span class='pagenum pncolor'><a id='page_45'></a>45</span><a name='chIV' id='chIV'></a>CHAPTER IV.—THE AEROPLANE IN DANGER.</h2>
+<p>
+A strong wind came out of the Western Sea
+at ten o’clock that night and swept the lofty
+plateau as a woman might have swept it with
+a new broom. Ned and Frank, pursuing their
+investigations in the cavern, knew nothing of
+what was going on at the camp, but Jack and
+Pat were not long in ignorance of the danger of
+the situation.
+</p>
+<p>
+With the first strong rush of wind the boys
+were on their feet, steadying the aeroplane, driving
+stakes wherever the nature of the ground
+permitted, and running bracing cords. The
+shelter tents went down instantly and were
+blown against the rocks of the east, where they
+waved canvas arms in the tearing breeze like
+sheeted ghosts.
+</p>
+<p>
+The black clouds which swarmed up from the
+valley brought no rain, but fitful flashes of lightning
+and deep-toned thunder made a threatening
+sky. The roaring of the swirling trees in the
+caÃąon and on the slopes came up to the ears of
+the boys like the boom of a strong surf.
+<span class='pagenum pncolor'><a id='page_46'></a>46</span>
+</p>
+<p>
+After persistent efforts the boys succeeded in
+bracing the aeroplane so that there was little
+danger of its being swept away, though they
+still remained with their backs to the wind, holding
+on. As time passed, they crept close together
+in order that the situation might be discussed.
+</p>
+<p>
+“Lucky thing we remained here,” Pat said,
+tugging with all his might to steady the monster
+machine against a particularly vicious dash of
+wind.
+</p>
+<p>
+“It would have gone sure, if we hadn’t,”
+Jack screamed back. “I wish Ned and Frank
+would come and help. My back is creaking like
+a shaft that needs oiling with the strain on it.”
+</p>
+<p>
+“A little help wouldn’t go amiss,” Pat admitted,
+shouting at the top of his lungs in order
+that he might be heard above the whistling of
+the storm.
+</p>
+<p>
+“I wonder if we’ll ever be able to put the
+tents up again?” Jack shouted. “They are flapping
+and snapping like musketry out there on the
+rocks. I hope they won’t blow away entirely.”
+</p>
+<p>
+Pat gazed anxiously in the direction indicated,
+but could only see pieces of canvas bellying
+up in the wind, mounting upward like balloons
+<span class='pagenum pncolor'><a id='page_47'></a>47</span>
+at times, then falling back to earth when a short
+lull came in the storm.
+</p>
+<p>
+“Why,” he cried, in a moment, “where’s
+Jimmie? I thought I saw him here a moment
+ago. Have you seen him?”
+</p>
+<p>
+“Not since the storm,” panted Jack.
+</p>
+<p>
+“He may have been smothered in his tent,”
+Pat shouted. “You hold on here while I go and
+look him up.”
+</p>
+<p>
+“Be sure that you keep close to the ground,”
+warned Jack. “If you don’t you’ll be blown
+away.”
+</p>
+<p>
+It was not at all difficult for the lad to reach
+the flapping tents, for the wind generously assisted
+him in the journey. Only that he crept on
+his hands and knees he would have been tossed
+against the wall where the tents lay.
+</p>
+<p>
+Struggling with the tearing canvas, bracing
+himself against the face of the cliff, the boy
+looked over the ruined tents but found no indication
+of the presence of the boy he sought, either
+dead or alive. Then he felt along the angle of
+the foot of the rise with no better success.
+</p>
+<p>
+“He’s not there,” he reported, crawling back
+to Jack, now braced tenaciously with his toes
+and elbows digging into the soil above the rock.
+</p>
+<p>
+“Did you find his clothes?” asked Jack.
+<span class='pagenum pncolor'><a id='page_48'></a>48</span>
+</p>
+<p>
+“Not a thing belonging to his outfit,” was
+the reply.
+</p>
+<p>
+“Well, he went to bed, didn’t he?” asked
+Jack, a sudden suspicion entering his mind.
+</p>
+<p>
+“He went into his tent,” was the reply,
+“but I did not see him undress.”
+</p>
+<p>
+Then Pat, much to his astonishment, heard
+Jack laughing as if mightily pleased over something
+that had taken place.
+</p>
+<p>
+“You’ve got your nerve!” he exclaimed.
+“Laughing at a time like this. I’ll bet the kid
+has been blown off the plateau.”
+</p>
+<p>
+There was now a little lull in the drive of the
+wind and Jack nudged his companion with his
+elbow, turning an amused face as he did so.
+</p>
+<p>
+“Blown off nothing!” he said. “You saw
+how he acted when Ned went off without him—how
+sulky he was?”
+</p>
+<p>
+“I noticed something of the sort.”
+</p>
+<p>
+“Well, Jimmie ducked after him!”
+</p>
+<p>
+“Why, he was told to remain here.”
+</p>
+<p>
+“He has been told that before,” Jack said,
+“and he’s never obeyed orders. He followed
+Ned from Manila to Yokohama, not long ago,
+and made a hit in doing it, too. Oh, it is a sure
+thing that Jimmie is not far from Ned at this
+minute.”
+<span class='pagenum pncolor'><a id='page_49'></a>49</span>
+</p>
+<p>
+“The little scamp!” grinned Pat.
+</p>
+<p>
+“He seems to think that Ned can’t get along
+without his constant presence and his pranks,”
+Jack continued. “He generally stirs something
+up in his immediate vicinity, but he’s a pretty
+good scout at that.”
+</p>
+<p>
+“I hope he is with Ned,” Pat said.
+</p>
+<p>
+The wind now died down a bit, so that it was
+no longer necessary to hold the aeroplane, and
+the boys, after seeing that the rope still held,
+began the work of repairing the tents.
+</p>
+<p>
+The clouds drifted away and the moon looked
+down as bravely as if it had not just hidden its
+face from sight at the threats of the wind! The
+electric flashlights with which the boys were
+well provided seemed inadequate and Pat started
+in to build a fire.
+</p>
+<p>
+“I don’t know about that,” Jack said. “If
+there had been a fire here when that wind came
+up it would have been roaring in the caÃąon now.
+The storm would have swept it down on the
+trees there, and the whole gully would soon have
+become a roaring furnace. Better cut out the
+fire.”
+</p>
+<p>
+“I guess you are right,” Pat said, reluctantly
+laying his dry faggots aside.
+<span class='pagenum pncolor'><a id='page_50'></a>50</span>
+</p>
+<p>
+While the boys worked, trying to restore the
+shelter tents to something like form, the wind
+came up once more and reached out for the aeroplane.
+Pat and Jack renewed their holding
+efforts, and thanked their stars that no fire had
+been built on the plateau, for the forest about
+was dry as tinder.
+</p>
+<p>
+Presently a voice which neither recognized
+came out of the shadows cast by a mass of clouds
+just then occupying the sky where the moon
+should have been.
+</p>
+<p>
+“Hello!” the voice said.
+</p>
+<p>
+The boys looked at each other in perplexity
+for a moment and then Jack answered back.
+</p>
+<p>
+“Hello!” he said.
+</p>
+<p>
+“Are you all safe up here, safe and sound?”
+the voice asked, and then the figure of a tall
+man, roughly dressed, but bearing the manner, as
+faintly observed in the darkness, of a gentleman,
+advanced toward the aeroplane, to which the
+lads were still devoting their whole attention.
+</p>
+<p>
+“Safe and sound!” repeated Pat.
+</p>
+<p>
+The stranger sat down by Jack’s side and
+laid hold of the aeroplane.
+</p>
+<p>
+“Pulls hard, doesn’t it?” he asked, as the
+machine, forced by the wind, drew stoutly on
+the ropes and the muscles of the boys.
+</p>
+<div class='figcenter' style='padding-top: 1em; padding-bottom: 1em'>

+<div><span class='pagenum pncolor'><a id='page_51'></a>51</span></div>
+<p>
+“Pulls like a horse,” Jack replied.
+</p>
+<p>
+“I’m Greer, of the forest service,” the
+stranger said, in a moment. “I saw a fire up
+here this afternoon, and I was afraid harm might
+come from it during the gale. One blazing
+brand down in that caÃąon, and millions of feet
+of timber would be destroyed.”
+</p>
+<p>
+“As you see,” Jack said, “we have no fire.”
+</p>
+<p>
+“This, I presume,” Greer said, still pulling
+at the machine, “is the aeroplane your friends
+came in this evening?”
+</p>
+<p>
+“The same,” replied Pat shortly.
+</p>
+<p>
+The lad was annoyed to think that the forester,
+as he called himself, had been watching
+them. If he had taken so much interest in their
+movements, Pat thought, why hadn’t he shown
+himself before?
+</p>
+<p>
+Jack’s thoughts seemed to be running in the
+same direction. In fact, both boys were suspicious
+of this soft-spoken stranger who had
+come to them out of the storm with questions
+on his lips.
+</p>
+<p>
+“Where are your friends?” Greer asked, in a
+moment. “I hope they are not out in the forest
+thinking of starting a fire?”
+</p>
+<p>
+“They’ve gone to the lake after fish,” Jack
+<span class='pagenum pncolor'><a id='page_52'></a>52</span>
+said, accounting for the absence of the others
+with the first words that came to his lips.
+</p>
+<p>
+Greer gave a quick start and leaned over to
+look into Jack’s face.
+</p>
+<p>
+“Down at the lake?” he repeated. “Not
+out in a boat in a storm like this?”
+</p>
+<p>
+“No,” replied Jack, gruffly, so gruffly, in
+fact, that the stranger caught the hostile note
+and turned away.
+</p>
+<p>
+“I’m always afraid of fire on a night like this,”
+Greer continued in a moment, “and rarely sleep
+until morning. My cabin is back on the mountain
+a short distance, some distance above this
+plateau. That’s how I happened to see what
+was going on here.”
+</p>
+<p>
+“Rather a lonely life,” Pat said, resolved to
+keep the fellow talking if he could. “Because,”
+he reasoned, “you can tell what’s in a man’s
+head if he keeps his mouth open and his tongue
+moving, but no one can tell the secret locked up
+behind closed lips.”
+</p>
+<p>
+“Yes, it is rather lonely,” Greer replied.
+“I’m glad you boys are here. Going to remain
+long?”
+</p>
+<p>
+“Only a few weeks—just to hunt and fish,”
+was Jack’s reply.
+<span class='pagenum pncolor'><a id='page_53'></a>53</span>
+</p>
+<p>
+“If you don’t mind,” Greer went on, “I’ll
+come down and visit you now and then.”
+</p>
+<p>
+The statement almost took the form of a
+question, and Jack gave a grudging answer that
+the visits would be a pleasure, though he believed
+that the man was arranging a way of watching
+their movements.
+</p>
+<p>
+“I wish this wind would go down,” Greer
+said, presently. “As I said before, I’m always
+afraid of fire on nights like this. See! The
+wind blows straight off the distant ocean strong
+and steady, and a fire started out there to the
+west would run over this plateau and over the
+mountain like a wash of tide.”
+</p>
+<p>
+“There’s nothing to burn on the plateau,”
+Jack said, glad of an opportunity to contradict
+the stranger.
+</p>
+<p>
+“Nothing to burn!” Greer repeated. “I
+reckon you don’t know much about forest fires,
+young man! Why, it would burn the soil down
+to bed rock, even evaporate the water in the
+rock itself and crumble it down to ashes. A
+forest fire is no joking matter.”
+</p>
+<p>
+The boys remained silent, looking cautiously
+into each other’s faces and both wondering how
+a forester, a man marooned in a great wilderness
+should be so exact in his speech, should wear
+<span class='pagenum pncolor'><a id='page_54'></a>54</span>
+such a shirt—actually a dress shirt—as they
+saw under his rough coat when the wind blew it
+aside.
+</p>
+<p>
+“I rather think there’s more company coming,”
+Greer continued, seeing that the boys
+were not inclined to comment on his warnings.
+“A moment ago I saw a flash of light at the foot
+of the rise to the west.”
+</p>
+<p>
+The wind was still blowing fiercely, but both
+boys turned and looked down the incline. There
+was a faint light there now, glimmering among
+the trees.
+</p>
+<p>
+“It looks like a lantern,” Greer said. “And
+the fellow seems about to climb the hill. Good
+luck to him, in this gale.”
+</p>
+<p>
+“It seems to me,” Pat said, “that the light
+we see is running along on the ground. If that
+should be a forest fire, there would be the dickens
+to pay to-night—and nothing to pay with!”
+</p>
+<p>
+“That is not the way forest fires start,”
+Greer said, turning indolently in the direction
+of the divide. “That is a man with a lantern.”
+</p>
+<p>
+The boys watched the glimmer below with
+interest. The man with the lantern, if there
+was a man and a lantern, seemed to be moving
+with the wind. Then, again, he seemed to divide
+himself, as the lower orders of life at the bottom
+<span class='pagenum pncolor'><a id='page_55'></a>55</span>
+of the seas divide themselves, appearing on both
+sides of a dark space at the same moment.
+</p>
+<p>
+They were satisfied that something unusual
+was going on, but were for the moment lulled
+into a half-sense of security by the positive assertions
+of the alleged forester. Presently they
+turned away from the scene below and fixed
+their eyes on the stranger.
+</p>
+<p>
+He was standing straight up, his tall figure
+braced against the wind, peering down into the
+caÃąon. Notwithstanding the steady wind, the
+sky was now comparatively free of clouds, and
+they saw him lift a hand with something bright
+shining in it.
+</p>
+<p>
+It appeared to the lads that he was signaling
+to some one in the caÃąon. They turned away
+instantly so that Greer did not note their observation
+of him, and again fixed their gaze
+on the slope to the west.
+</p>
+<p>
+The lantern, if there was a lantern, was growing
+larger! It was showing itself in half a dozen
+places now, and was tracing lights far up in the
+crotches of dead trees. Then the penetrating
+odor of burning wood and grass came up the
+slope.
+</p>
+<p>
+Filled with a fear which could hardly be
+expressed in words, the boys faced Greer again.
+<span class='pagenum pncolor'><a id='page_56'></a>56</span>
+He still stood facing the caÃąon to the south, but
+his hands were not lifted now. There was no
+need for that, the boys thought, for the previous
+signal seemed to have sufficed.
+</p>
+<p>
+Among the dry faggots on the ground at the
+bottom of the caÃąon there was another man with
+a lantern. He, too, if there was such a man, was
+moving about among the trees and dividing himself
+into sections, as the rudimental creatures of
+the world multiply themselves. Pat sprang to
+Greer’s side and shook him roughly by the arm.
+</p>
+<p>
+“There’s a fire down there!” he cried.
+</p>
+<p>
+In the uncertain moonlight the boy saw the
+stranger’s face harden.
+</p>
+<p>
+“You are mistaken,” he said, turning away
+toward the lake.
+</p>
+<p>
+“Smell the smoke!” Jack shouted. “I tell
+you the forest is on fire on two sides of us.”
+</p>
+<p>
+“Then your friends have set the fires!”
+Greer shouted, against the wind. “I have been
+suspicious of you all along—ever since you failed
+to satisfactorily account for the absence of your
+friends. It is all very well for you to come here
+in an aeroplane and start a conflagration! But
+how do you think that we, who are not so well
+provided with means of getting away, are to
+escape death?”
+<span class='pagenum pncolor'><a id='page_57'></a>57</span>
+</p>
+<p>
+Pat drew back his hand, as if to strike the
+fellow, but Jack restrained him.
+</p>
+<p>
+“You set the fires!” Pat shouted, then.
+“You set it through your fellow conspirators!
+I saw you signaling to the caÃąon!”
+</p>
+<p>
+“You’re no more a forester than I am!” Jack
+added. “You’re a scoundrel, and ought to be
+sent to prison for life.”
+</p>
+<p>
+There was no more talk for a time. Greer
+stood defiantly against the wall of rock to the
+east, as if fearful of an attack from behind, his
+right hand in his bulging pocket. The boys
+knew that he had a weapon there, and their own
+hands were not empty.
+</p>
+<p>
+The aeroplane drew and shivered in the rising
+gale, but now little attention was paid to it.
+Pat and Jack were listening for some indication
+of the return of Ned and Frank. No farther
+fable of a man with a lantern was necessary, for
+fire was racing up the western slope, heading
+directly for the plateau and the priceless aeroplane.
+Down in the caÃąon the flames were
+leaping from tree to tree. A stifling smoke filled
+the air, always in swift motion, but stifling still.

+<p>
+“Smugglers!” Frank exclaimed, dropping an
+armful of unopened opium tins on the floor of
+the cavern. “Smugglers, all right, all right!”
+</p>
+<p>
+Ned looked the tins over carefully. They
+were well covered with Chinese characters, and
+were dirty, as if they had been hidden away in
+the earth for a long time.
+</p>
+<p>
+“Who would have suspected it?” Frank continued.
+“We are close to the British frontier,
+but, all the same, this seems to me to be an awkward
+place to land and store the dope stuff.”
+</p>
+<p>
+“Where did you find it?” asked Ned.
+</p>
+<p>
+“There is a false back to that cupboard in
+the north wall,” Frank replied. “When I
+knocked on the boards they gave forth a hollow
+sound, and so I tore one away. Hence the
+opium. And there are pipes there, too—just
+such pipes as one sees in the joints on Pell
+street, in little old New York.”
+</p>
+<p>
+“You remember what Jimmie said?” asked
+Ned.
+<span class='pagenum pncolor'><a id='page_59'></a>59</span>
+</p>
+<p>
+“I remember a good many things the little
+rascal has said,” was the laughing reply. “He’s
+always saying something.”
+</p>
+<p>
+“Well,” Ned continued, “the boy was right
+when he expressed his opinion of the heelless
+footprints in one word.”
+</p>
+<p>
+“Chinks!” grinned Frank. “Of course!”
+</p>
+<p>
+The boys now went over to the cupboard in
+the niche and began tearing away the boards.
+After a few had been displaced Ned stopped and
+began experimenting in fitting them in position
+again.
+</p>
+<p>
+“What’s doing now?” demanded Frank.
+</p>
+<p>
+“We must remove them so as to be able to
+return them as we found them before we leave,”
+Ned replied. “It is important that the inhabitants
+of this robber den do not know that we
+have discovered it.”
+</p>
+<p>
+“Don’t you ever think they don’t know it
+right now,” Frank said. “We haven’t seen any
+of them since they rowed around the point, but
+they’re stirring about, just the same. We may
+see more of them before we get out of this cavern.”
+</p>
+<p>
+“Well,” Ned said, “we must take all the
+precautions needful, and if they are of no avail
+we shall not be to blame for what takes place.
+<span class='pagenum pncolor'><a id='page_60'></a>60</span>
+Even if they know that we have found the cavern,
+they need not know that we have penetrated
+into the office chamber. Now, draw that last
+board away carefully, and we’ll see what there
+is behind the false bottom.”
+</p>
+<p>
+Frank drew the board away and was confronted
+by a long, low tunnel—an uncanny, narrow
+tunnel which had evidently been enlarged
+from a fault in the rock, and which appeared to
+penetrate far into the bulk of the mountain.
+</p>
+<p>
+“See!” he cried. “The cupboard was built
+at the mouth of a cross fault in the rock, and
+there is no knowing what is behind it. Hold
+your flashlight higher and I’ll crawl in and
+look about.”
+</p>
+<p>
+“Be careful,” Ned warned. “I have seen
+great holes at the bottom of tunnels like that.
+Don’t break your neck, or tumble down so far
+that I can’t fish you out.”
+</p>
+<p>
+Frank grinned and crept through the opening
+made by the removal of the back of the closet.
+The place was not high enough for him to stand
+upright, and so he proceeded on hands and knees.
+</p>
+<p>
+“This is a bedroom,” he shouted back to
+Ned. “There’s lots of ticks and blankets here.”
+</p>
+<p>
+There was silence for a moment, and then the
+boy’s voice came from farther in the tunnel.
+<span class='pagenum pncolor'><a id='page_61'></a>61</span>
+“And here’s kegs of whisky,” he cried. “It
+smells like a Bowery saloon. Come on in!”
+</p>
+<p>
+“I think one of us would better remain outside,”
+Ned replied. “I wouldn’t like to be surprised
+while in there and fastened in with rocks.”
+</p>
+<p>
+Frank went on down the tunnel for some distance,
+calling back, now and then, to report his
+discoveries. There were weapons stored there,
+barrels of gasoline, packages of dynamite.
+</p>
+<p>
+Then, for several long minutes, there came
+no voice from the interior, and Ned put his head
+inside and called out softly:
+</p>
+<p>
+“Frank!”
+</p>
+<p>
+There was no reply, and Ned was about to
+advance into the opening when the sound of a
+footstep came on the rocky floor of the chamber
+just behind him. The footstep was a stealthy
+one, halting, as if some person were listening between
+the steps. Ned’s first act was to shut the
+light off from his electric candle.
+</p>
+<p>
+Then he moved away from the niche in the
+wall where the cupboard had been built in and
+waited. His greatest fear was that Frank would
+turn about and show his light, and so expose
+them both to danger. While he listened, almost
+holding his breath, the steps came nearer to the
+cupboard and halted.
+<span class='pagenum pncolor'><a id='page_62'></a>62</span>
+</p>
+<p>
+But the halt was only for an instant, for the
+unseen figure moved on again, this time back
+toward the entrance. Directly the footsteps
+were heard no more, and then the crash of falling
+rocks reached the boy’s ears. He did not have
+to think long in order to understand what that
+sound portended.
+</p>
+<p>
+He knew that they had been observed by
+some of the outlaws who made the cavern their
+home and their storehouse as well, had been followed
+into the inner chamber, and were now to
+be fastened into the cavern, probably left there
+to starve, with tons of rock bulking before the
+entrance to the third chamber. It was not a
+pleasant situation.
+</p>
+<p>
+While he studied the peril over in as optimistic
+a mood as was possible under the circumstances,
+he heard Frank calling to him from the
+narrow tunnel behind the cupboard. The boy
+was evidently excited, for his voice rang high.
+</p>
+<p>
+“Ned!” he cried. “Come on in!”
+</p>
+<p>
+The noise of falling, rolling rocks stopped at
+the sound of Frank’s voice, and Ned thought he
+heard a half-suppressed chuckle in the darkness.
+</p>
+<p>
+“Hurry!” came Frank’s voice once more.
+“There’s something in here that takes the nerve
+out of me.”
+<span class='pagenum pncolor'><a id='page_63'></a>63</span>
+</p>
+<p>
+There was a low exclamation of rage at the
+entrance, where the stones were piling up, and
+then the grind of falling rocks was continued.
+Ned had, of course, no idea as to how many persons
+were engaged in building up the wall which
+threatened to shut him in until life was extinct,
+or exactly how it was being done, but he knew
+that the correct thing for him to do was to prevent
+the completion of the work.
+</p>
+<p>
+If only one man had arrived at the cavern he
+might be frightened and driven away by a little
+shooting. With bullets whizzing through what
+was left of the opening, the man who was building
+the crude wall would not be likely to present his
+body before the space still uncovered. This
+reasoning brought the boy to a consideration of
+the matter of ammunition, but he decided that,
+with the cartridges carried by Frank, they could
+defend the place for a long time.
+</p>
+<p>
+But another question intervened. The rocks
+which, though unseen, he knew to be blocking the
+space where the rug had hung were undoubtedly
+falling from a distance. They might have been
+stored above the natural doorway for the very
+purpose to which they were now being put.
+</p>
+<p>
+If this were true, then the building of the
+trap would continue, regardless of his bullets.
+<span class='pagenum pncolor'><a id='page_64'></a>64</span>
+While he studied over this problem, slowly making
+up his mind to put it to the test, Frank’s
+voice came from the tunnel again.
+</p>
+<p>
+“What’s doing out there?” the boy asked.
+“Why don’t you come in here?”
+</p>
+<p>
+“Shut off your light!” ordered Ned, as a
+glimmer showed inside.
+</p>
+<p>
+“Not me,” replied Frank. “I need all the
+light I can get in here!”
+</p>
+<p>
+“What have you found?” asked Ned anxiously.
+</p>
+<p>
+Frank did not reply instantly, and Ned
+heard the rattle of stones while he waited for
+his answer. The task of piling up the wall was
+progressing rapidly, and it seemed to the boy
+that the stones were all falling from a distance.
+</p>
+<p>
+“Shut off your light and come out,” Ned said,
+impatient at the hesitation.
+</p>
+<p>
+“I wouldn’t stay here in the dark for a thousand
+dollars a second,” Frank replied, “but I’ll
+come out. Why don’t you show a light?”
+</p>
+<p>
+“I’m not looking for any chance bullets,” Ned
+replied, coolly. “We’re caught, my boy, and
+it is up to us to move cautiously. Why don’t
+you turn off your light?” he added, half angrily.
+</p>
+<p>
+“Oh,” Frank replied, “you’re getting it out
+there, too, are you? Well, I was trying to save
+<span class='pagenum pncolor'><a id='page_65'></a>65</span>
+you a shock. There’s a dead man in here, and
+I’m going to keep my light going until I’m out
+of the hole. I did shut it off once, and felt the
+grasp of a hand on my neck—and there wasn’t
+any hand there either.”
+</p>
+<p>
+“A dead man?” repeated Ned.
+</p>
+<p>
+“Sure,” Frank replied. “And he’s not been
+dead very long, at that.”
+</p>
+<p>
+Again the boy heard that vicious chuckle at
+the entrance. Then a voice came out of the
+mouldy darkness:
+</p>
+<p>
+“How are you getting on in the Secret Service,
+Ned Nestor?” the voice asked.
+</p>
+<p>
+“Finely!” Ned called back, but it seemed to
+him that his voice shook with the peril of the
+situation. He was known, his mission there
+was no secret, the enemies of the government
+were already on the ground, ready to combat
+him in his work. Just how far their hostility
+would extend was evidenced by the fall of rocks
+outside. It seemed to the boy that the struggle
+would be to the death.
+</p>
+<p>
+“Who are you talking to?” Frank asked.
+</p>
+<p>
+Ned did not reply to the question, for there
+came the sound of a scuffle outside, then a shot,
+a cry of pain, and the cavern was still as a grave.
+<span class='pagenum pncolor'><a id='page_66'></a>66</span>
+</p>
+<p>
+In the silence Frank’s movements were
+heard, and Ned knew that he was backing out
+of the tunnel, with his light still burning. Entirely
+at a loss to account for the fracas outside,
+Ned awaited his approach with a fast-beating
+heart. When at last he shut off his electric
+searchlight and dropped from the tunnel through
+the old cupboard Ned seized his hand and drew
+him away.
+</p>
+<p>
+“Did you fire that shot?” Frank whispered.
+</p>
+<p>
+“No,” was the reply. “There’s fighting
+outside, and the shot was fired there. Now, I
+had a notion of sending a stream of bullets
+through the doorway, but the persons who are
+fighting the man who came upon us here may
+be our friends, so we must be careful what we do.
+Here. Take my flashlight. Open the two at
+the same instant and turn the rays on the doorway.
+I’ll be ready with my gun.”
+</p>
+<p>
+But before this movement could be carried
+out a voice the boys knew came out of the darkness.
+</p>
+<p>
+“Wonder you wouldn’t give a fellow a lift,”
+Jimmie said, in a panting tone. “I’ve got to
+the limit with this big stiff.”
+</p>
+<p>
+The lights were on instantly, with Ned and
+Frank bounding toward the opening. The way
+<span class='pagenum pncolor'><a id='page_67'></a>67</span>
+was narrow, for many rocks had been dropped
+down from a broad ledge just above, but they
+managed to crawl through. But before Ned
+could reach the struggling pair on the floor the
+under figure wiggled away, staggered for an
+instant, and then made for the outer air at good
+speed.
+</p>
+<p>
+Jimmie sat upon the stone floor with a disgusted
+look on his freckled face.
+</p>
+<p>
+“Now see what you’ve been an’ gone an’
+done!” he cried. “You’ve let me pirate get
+away! But he took a bullet with him,” he
+added.
+</p>
+<p>
+“How many were here?” asked Ned, shutting
+off his light and telling Frank to do the
+same. “How many men did you see?”
+</p>
+<p>
+“Just that one,” Jimmie replied, sorrowfully,
+“an’ he got away!”
+</p>
+<p>
+Ned advanced to the entrance and listened.
+At first he heard the sound of limping footsteps,
+then the sweep of oars. He ran down to the
+beach and swept his light over the waters of the
+lake. A slender boat was speeding far to the
+north, and a solitary rower was bending to his
+work.
+</p>
+<p>
+Now, for the first time, Ned noted that a
+fierce gale was blowing from the west, and his
+<span class='pagenum pncolor'><a id='page_68'></a>68</span>
+thoughts went back to the plateau where the
+aeroplane lay exposed to the storm. He ran
+back to the cavern, barely escaping being blown
+off his feet on the way, and called to the boys.
+</p>
+<p>
+“There’s a stiff wind blowing,” he said, “and
+I’m afraid for the aeroplane. We must get back
+to the camp immediately.”
+</p>
+<p>
+“The wind was on when I came in,” Jimmie
+said, “an’ it near blew me into the lake, even
+if I did hold on to the trees. We can never
+make the hill in the storm.”
+</p>
+<p>
+“We’ve got to,” Ned insisted.
+</p>
+<p>
+“Besides,” Jimmie continued, “we want to
+find out about the dead man Frank has been
+telling me about. We can’t take him with us,
+an’ he will not be here when we come back.
+Whatever we learn about him, an’ the cause of
+his death, must be learned now.”
+</p>
+<p>
+“Sometimes, Jimmie,” Frank burst out,
+“you exhibit signs of almost human intelligence!”
+</p>
+<p>
+“The boy is right,” Ned observed. “I’m
+so rattled that I hardly know what I’m about.
+We ought to be in pursuit of that rascal who is
+rowing on the lake, we ought to be on the plateau,
+looking after the aeroplane, and we ought
+to be here, finding out if a murder has been committed.”
+<span class='pagenum pncolor'><a id='page_69'></a>69</span>
+</p>
+<p>
+“It is a murder, all right,” Frank said, “for
+the floor in the tunnel is sticky with blood.”
+</p>
+<p>
+“I’m goin’ in there!” Jimmie exclaimed.
+</p>
+<p>
+“Go if you want to,” Frank grunted.
+</p>
+<p>
+Ned laid a hand on Jimmie’s arm as he started
+away.
+</p>
+<p>
+“If you don’t mind,” he said, “I’d much
+rather you remained on guard. You have keen
+eyes, and may be of great service here.”
+</p>
+<p>
+“All right!” the boy said. “I’ll do anything
+you ask me to if you don’t leave me out of the
+game.”
+</p>
+<p>
+“No danger of your getting into the dust
+heap,” Frank laughed. “How long have you
+been prowling about here?”
+</p>
+<p>
+“Just a short time,” was the reply. “I remained
+in the tent until I thought Pat an’ Jack
+were asleep an’ then cut my lucky. Say, but
+the wind was blowin’ when I slid down the slope
+toward the lake.”
+</p>
+<p>
+“It must be fierce up on the plateau,” Frank
+admitted. “Say,” he added, turning to Ned,
+“if you don’t mind, I’ll go on up the hill and help
+the boys with the aeroplane. It would be a
+tragedy if it should be destroyed now.”
+</p>
+<p>
+“All right,” Ned said. “Get up there as
+soon as possible. The boys may be having
+<span class='pagenum pncolor'><a id='page_70'></a>70</span>
+trouble with the ’plane. And Jimmie,” he added,
+“suppose you keep an eye on the plateau?
+The lads may signal.”
+</p>
+<p>
+“Too dark for that,” the boy replied, “but
+I’ll keep a sharp lookout, just the same. Go on
+and look over the man Frank found under the
+mountain.”
+</p>
+<p>
+Frank moved on up the hill, clinging to trees
+as he advanced, and stooping low, even then, to
+escape the force of the wind, while Jimmie stationed
+himself in the opening and looked out on
+the lake. Ned disappeared in the cavern, and
+the boy saw his torch grow fainter as he climbed
+through the narrow opening left in the rock
+which had been thrown over the natural doorway.
+</p>
+<p>
+It was getting late and the boy was sleepy,
+but he struggled manfully to keep his eyes open.
+Directly, however, he had no trouble in this regard,
+for he started up with a strange, acrid odor
+in his nostrils. The low-lying sky was aflame.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_71'></a>71</span><a name='chVI' id='chVI'></a>CHAPTER VI.—ABOVE THE CLOUDS AT NIGHT.</h2>
+<p>
+The wind gained strength as the heat of the
+forest fires increased. The roaring of the gale
+and the heavy undertone of the racing flames
+effectually drowned the voice of the forester,
+and it was only by the motion of his lips that the
+boys knew that he was trying to talk to them.
+</p>
+<p>
+Presently he threw his hands high above his
+head, weaponless, then lowered one and beckoned
+to them. Still keeping grasp on their revolvers,
+the boys approached him. His face was deadly
+pale, save for the glow of the fire which shone
+unnaturally on the wall behind him.
+</p>
+<p>
+“This is no time for accusations,” he shouted.
+“We must do something to check the fire.”
+</p>
+<p>
+“What is to be done?” Jack demanded, half
+won over by the apparent distress of the fellow.
+</p>
+<p>
+“The blaze will burn itself out against the
+mountains,” was the reply, shouted at the top
+of the speaker’s lungs, “but the fire in the caÃąon
+must be checked by going on ahead and felling
+trees.”
+<span class='pagenum pncolor'><a id='page_72'></a>72</span>
+</p>
+<p>
+“Won’t it burn itself out there, too?”
+asked Pat.
+</p>
+<p>
+“I’m afraid not,” was the shrill reply.
+“There is an opening from the top of the
+caÃąon to a valley in a fold of the hills. The
+fire will do incalculable damage if it passes
+through that.”
+</p>
+<p>
+“What do you suppose we can do against a
+fire like that?” demanded Pat. “An army
+could not stop the blaze now.”
+</p>
+<p>
+“You are mistaken!” shrilled the other.
+“Three choppers can clear a space which the
+fire will not cross.”
+</p>
+<p>
+“We’ll get our axes and try,” Jack said, reluctantly.
+</p>
+<p>
+“Then make haste!” Greer shouted. “At all
+events we must leave this place, for the fire will
+soon be here. Come!”
+</p>
+<p>
+When the boys turned to verify this statement
+they saw that the planes of the aeroplane
+were red with the reflection of the blaze below,
+and that the creeping fire was already showing
+at the lip of the plateau.
+</p>
+<p>
+“The aeroplane is doomed, I guess,” wailed
+Jack, and Pat thought he saw a look of satisfaction
+in Greer’s face as the words reached
+his ears.
+<span class='pagenum pncolor'><a id='page_73'></a>73</span>
+</p>
+<p>
+The smoke was now rolling over the plateau
+in great clouds, but through it Pat thought he
+saw figures moving from the south slope toward
+the aeroplane. Calling out to Jack, he sprang
+toward the machine, the suspicion in his mind
+that these were confederates of the alleged forester,
+and that the machine was, after all, the
+main point of attack.
+</p>
+<p>
+Greer saw the movement and darted toward
+the boy as if to block his way, but Pat struck
+out viciously and turned him back. Then a bit
+of flame sprang up in the cloud of smoke which
+was sweeping over the plateau. It seemed to
+Pat that an attempt to burn the machine in
+advance of the arrival of the forest fire was being
+made.
+</p>
+<p>
+When he darted forward again Greer caught
+him by the shoulder and hurled him away.
+</p>
+<p>
+“Get your axes!” he shouted. “There is no
+time to waste here.”
+</p>
+<p>
+Then the smoke lifted for an instant and Pat
+saw three figures rise above the rim of the
+northern slope and hasten toward the aeroplane.
+Their arrival there was followed by shots and
+calls for assistance. Then the smoke shut down
+again, and the roaring of the flames drowned
+all other sounds.
+<span class='pagenum pncolor'><a id='page_74'></a>74</span>
+</p>
+<p>
+Greer stood for an instant, braced against
+the wind, shielding his face from the hot blasts
+scorching the grass of the plateau, then turned
+and ran. Then both boys heard a call from the
+direction of the machine.
+</p>
+<p>
+“The way is clear to the cavern!” were the
+words they heard. “Remain there until we return!”
+</p>
+<p>
+“That’s Ned,” shouted Pat. “Just in time
+to save the aeroplane.”
+</p>
+<p>
+Almost before the words were out of his
+mouth there came a lull in the wind and the
+great machine ran forward a few yards, then
+swung into the air. At that moment Frank
+came running toward the two astonished boys.
+</p>
+<p>
+“We’ve got to leg it!” Frank shouted, his
+mouth close to Jack’s ear. “Drop low on the
+ground so as to get fresh air and run!”
+</p>
+<p>
+Jack, although he had heard Ned’s voice
+giving directions, and although he knew that
+Frank was by his side, could hardly sense the
+situation, or all that had taken place. The
+action had been so swift that he could not yet
+realize that Ned had snatched the aeroplane
+away from certain destruction and lifted it into
+the stormy sky in so short a time.
+<span class='pagenum pncolor'><a id='page_75'></a>75</span>
+</p>
+<p>
+However, he did not stop then to place the
+events in neat order in his mind, for the fire was
+working across the scant vegetation of the plateau
+and the air was hot and stifling. It was all
+like a page out of the Arabian Nights, but he put
+the wonder of it away, grasped Frank’s hand,
+and, crouching, ran toward the incline leading
+to the lake. There was safety there, at least.
+</p>
+<p>
+Now and then, in their swift flight, the boys
+stopped and looked upward, hoping to learn
+something of the fate of the aeroplane, but the
+great machine was not in sight.
+</p>
+<p>
+“Ned never can make it live in this gale!”
+Jack almost sobbed, when, at last, they all came
+to a halt at the margin of the lake. “The whole
+shebang will go to pieces and the boys will be
+killed.”
+</p>
+<p>
+“Aw, forget it!” grunted Pat. “I’m not in
+love with airships, but I know that Ned wouldn’t
+have gone up unless he knew that he could handle
+the machine. He’ll lift above the divide and
+drive straight before the wind. The good Lord
+only knows how far the gale will take him, but
+I’m betting my head against turnips that he’ll
+come back by morning, asking why breakfast
+isn’t ready!”
+<span class='pagenum pncolor'><a id='page_76'></a>76</span>
+</p>
+<p>
+“How did you get wise to the trouble up
+here?” Jack asked of Frank.
+</p>
+<p>
+“Why, I don’t exactly know,” the boy replied.
+“Ned sent me on ahead to look out for
+the aeroplane. He said he wanted to remain
+in the cavern and investigate. I was making
+slow progress up the hill when Ned and Jimmie
+came running after me. I had noticed long before
+that the sky looked like fires were burning
+somewhere.”
+</p>
+<p>
+“I should say so,” Pat cut in. “The clouds
+looked like they had been soaked in red paint.”
+</p>
+<p>
+“When Ned came up to me, running like a
+racehorse,” Frank went on, “he said he was
+going to take the aeroplane out, wind or no wind.
+I didn’t have much chance to talk with him, but
+I understood that he was going to do just what
+Pat has suggested—run before the wind and
+swing back whenever he could.”
+</p>
+<p>
+“I presume Jimmie is good and scared by
+this time!” Jack commented.
+</p>
+<p>
+“When we got to the machine,” Frank went
+on, “we found two men there with some sort of
+torches in their hands, trying to set the machine
+on fire. We caught them unawares and left
+them lying there. I hope they didn’t get burned
+to death.”
+<span class='pagenum pncolor'><a id='page_77'></a>77</span>
+</p>
+<p>
+There was a short cessation of speech while
+the boys listened to the roaring of the flames
+and watched the fire mounting into the sky. It
+was a wild scene—one calculated to bring terror
+to the breast of any human being. The wind
+was dying down a little, but the clouds were still
+driving fast before it, their edges tinged with
+flame so that they resembled golden masses
+floating across an eternity of space clothed in
+smoke.
+</p>
+<p>
+While the boys watched the great display
+Frank pointed to a wall of flame rounding the
+corner of the plateau.
+</p>
+<p>
+“The fire will burn this slope,” he said, “and
+we’ve either got to get into the cave or out on
+the lake. Which shall It be?”
+</p>
+<p>
+“The cave for mine!” Jack cried.
+</p>
+<p>
+“And mine,” echoed Pat. “Who knows
+what the fire will do to the lake?”
+</p>
+<p>
+But Frank had had previous experience in
+the cavern. He was thinking of the still figure
+he had found lying there, and of the dark stains
+on the floor.
+</p>
+<p>
+“If we could find a boat,” he said, without
+mentioning his real reason for objecting to the
+cave, “we might get along very well on the lake.
+We don’t know what stifling air we shall find in
+<span class='pagenum pncolor'><a id='page_78'></a>78</span>
+the cave, and, besides, the men we have just had
+a fracas with may return at any time. It
+wouldn’t be nice to be locked up in that hole in
+the ground.”
+</p>
+<p>
+The wind was dying down to a steady breeze,
+and the fires seemed to burn lower. The clouds
+above were dark and threatening, save where
+gilded by the reflection from below, and seemed
+to be massing. Frank held up a hand and
+shouted.
+</p>
+<p>
+“Rain!” he cried. “Rain!”
+</p>
+<p>
+It was no gentle spring shower that opened
+upon the earth then. The fountains of the
+great deep seemed to have opened wide. The
+water fell in sheets, and in an instant the boys
+were wet to the skin.
+</p>
+<p>
+“Better than fire!” Jack suggested.
+</p>
+<p>
+The rain pelted down upon the forest fires
+viciously, and the hissing protests of the angry
+embers rose in the air. Through the thick veil
+of the rain clouds of steam could be seen rolling
+over the lake and along the threatened incline.
+In ten minutes water was pouring down the
+steep hill in sheets and the fires were leaping no
+more.
+</p>
+<p>
+Pleased as the boys were at the opportune
+arrival of the rain-bearing clouds, they could not
+<span class='pagenum pncolor'><a id='page_79'></a>79</span>
+help wondering if the freak of chance which had
+preserved the forests of northern Montana had
+not brought Ned and Jimmie sudden death.
+</p>
+<p>
+“They never can handle the machine in such
+an air-ocean,” Jack declared, but the more optimistic
+Pat asserted that Ned must have been
+a mile above the rain clouds before a drop of
+water fell.
+</p>
+<p>
+“I guess the fire brought this rain on,”
+Frank said, wiggling about in his wet garments,
+“but it’s just as wet as if brought about by some
+other means. What are we going to do now?”
+</p>
+<p>
+“Why not go to the cave until the rain
+stops?” asked Pat.
+</p>
+<p>
+“It is colder in there than it is here,” Frank
+said, still thinking of the silent figure in the narrow
+tunnel back of the cupboard.
+</p>
+<p>
+“We can’t get any more water in our clothes
+and hides than we have now,” Jack observed,
+“so we may as well stay outside and watch for
+Ned and the aeroplane. I don’t believe any
+other person ever took an aeroplane up in such
+a storm. I’m afraid Ned was smashed against
+the divide.”
+</p>
+<p>
+“Ned’s all right,” insisted Frank. “Suppose
+we go back to the plateau and see if there’s
+anything left of our tents.”
+<span class='pagenum pncolor'><a id='page_80'></a>80</span>
+</p>
+<p>
+“I’m game for that,” Pat said, “but,” he
+added, turning a keen gaze on Frank, “I’d like
+to know why you object to going to the cave.
+Jack and I would like to see it.”
+</p>
+<p>
+“Well,” Frank replied, not without some
+hesitation at bringing the scene in the tunnel
+back to his mind in form for expression in words,
+“there’s a crime been committed in the cave,
+and it’s uncanny.”
+</p>
+<p>
+“A crime!” repeated Pat, all excitement at
+the suggestion of another adventure, “what kind
+of a crime?”
+</p>
+<p>
+“A murder,” replied Frank, with a shiver.
+</p>
+<p>
+“Let’s go in and see,” Pat said.
+</p>
+<p>
+“Frank’s afraid,” Jack put in.
+</p>
+<p>
+“Of course I’m afraid,” Frank admitted.
+“You go in there, and crawl on your knees
+through the thick air of a narrow tunnel, and
+put your hand on a dead man’s face, and feel
+your other hand slipping in the blood on the
+floor, and you’ll be afraid, too. I’m not going
+back there.”
+</p>
+<p>
+“We can stand here in the rain all night, if
+you want to,” Pat said, with scorn in his voice.
+“Rainwater is said to be good for the complexion.”
+<span class='pagenum pncolor'><a id='page_81'></a>81</span>
+</p>
+<p>
+The wind was slowing down and the rainfall
+was not so heavy as before. The boys, Pat and
+Jack, joking Frank about his terror for the cave,
+and Frank just a little angry, began the ascent of
+the slope leading to the plateau.
+</p>
+<p>
+“The rain saved the trees next to the mountain,”
+Pat said, presently, “and if it checked the
+fire on the plateau at the same line our tents are
+all right. Say,” he added, “who ever heard of
+such a downpour as that. I reckon the rain
+swept in from the ocean in heavy clouds which
+were broken open by the mountains.”
+</p>
+<p>
+“Much you know about it!” laughed Jack.
+“You talk as if you could cut a cloud with a
+knife.”
+</p>
+<p>
+“Anyway,” persisted Pat, “the water tumbled
+out and checked the fires. Wonder what
+became of the man who said his name was Greer?
+He was standing in with the men who were trying
+to burn the aeroplane, all right enough, and
+I believe the whole circus was started just to
+destroy the airship and bring Ned’s investigations
+to a close.”
+</p>
+<p>
+“We always do get into the thick of it at the
+first jump,” Frank said, remembering the bomb
+under the cottage in the Canal Zone and the
+<span class='pagenum pncolor'><a id='page_82'></a>82</span>
+raid on the nipa hut in the Philippines. “Whenever
+we’ve got anything coming to us, we get it
+by lightning express.”
+</p>
+<p>
+“You bet we do!” Jack exclaimed. “Now
+we’re getting a clear sky,” he added, pointing
+upward, “and we’re getting it short order time,
+too!”
+</p>
+<p>
+The heavy clouds were gone, the moon was
+smiling down on the drenched earth, the stars
+were winking significantly toward a spot on the
+plateau where two unrecognizable figures, half
+burned away, were lying. When the boys
+reached the top of the climb and advanced to the
+spot where the aeroplane had stood they turned
+sick with the horror of the thing.
+</p>
+<p>
+“I almost wish we had let them destroy
+the aeroplane,” sighed Frank. “I don’t like
+to think that these men came to their death
+through us. It is awful!”
+</p>
+<p>
+“Did you shoot them?” asked Pat.
+</p>
+<p>
+Frank shook his head.
+</p>
+<p>
+“They shot at us,” he said. “They fired
+as soon as we got to the rim of the dip, but missed
+because of the smoke and the wind. Then we
+rushed them, and they went down—to escape
+punishment, I thought—and so Ned got the
+aeroplane away.”
+<span class='pagenum pncolor'><a id='page_83'></a>83</span>
+</p>
+<p>
+“Then you had nothing to do with their
+death,” consoled Pat. “They came here to
+commit a crime and were overcome by the smoke
+and heat.”
+</p>
+<p>
+Frank would gladly have accepted this version
+of what had taken place, but he could not
+bring his mind to do so at once. The horror of
+what he had found in the cave was still upon
+him.
+</p>
+<p>
+Leaving the spot where what remained of
+the outlaws lay, the boys hastened to the wall
+of rock which terminated the plateau on the east.
+The rain had indeed saved the tents from destruction.
+The canvas was huddled against the
+wall, stained with smoke and heavy with rain,
+but in fairly good condition.
+</p>
+<p>
+“We’ll have to remain here, or about here,
+until Ned comes,” Pat said, “so we may as well
+put the tents up. I wonder if it isn’t most
+morning?”
+</p>
+<p>
+“Does that mean that you are getting hungry?”
+grinned Jack.
+</p>
+<p>
+“You bet it does!” was the reply. “Anyway,
+I’m going to see if I can find dry wood
+enough for a fire. If I can I’ll make some hot
+coffee. Ned will see the fire, and know we are
+not in the cave.”
+<span class='pagenum pncolor'><a id='page_84'></a>84</span>
+</p>
+<p>
+Then an exclamation from Frank called the
+speaker’s attention to the clear sky over the divide.
+The upper strata of clouds were drifting
+westward on a high current of air—what few
+clouds there were—and far up in the blue, the
+moonlight trimming the planes with silver, rode
+the aeroplane, seemingly intact, and working
+back on the high current toward the Pacific
+coast.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_85'></a>85</span><a name='chVII' id='chVII'></a>CHAPTER VII.—A KEY WITH A BROKEN STEM.</h2>
+<p>
+The lights were burning low in a bachelor
+flat on a noisy street corner in the city of San
+Francisco, and a man of perhaps thirty lay on
+a couch with his eyes closed. There were in
+this sitting room, which faced one of the noisy
+streets, a grand piano, a costly music cabinet, a
+walnut bookcase filled with expensively bound
+volumes, numerous lazy chairs of leather, and
+the rug on the polished floor was rich and soft.
+The occupant of the flat evidently enjoyed
+luxurious things and had the money to pay
+for them.
+</p>
+<p>
+When a clock in a distant steeple struck midnight
+there came a knock at the locked door in
+the main corridor which connected with the
+private hallway on which the flat opened. A
+Japanese servant, small, obsequious, keen-eyed,
+opened the door, after the hesitation of a moment,
+and peeked out. He would have closed
+it again instantly, seeing a stranger there, only
+Ned Nestor, who had anticipated some action
+<span class='pagenum pncolor'><a id='page_86'></a>86</span>
+of the kind, thrust a shoe into the opening, and,
+reaching in, unfastened the chain.
+</p>
+<p>
+“I wish to see Mr. Albert Lemon,” he said.
+</p>
+<p>
+The Jap tried to force the door back and lock
+it, but was unsuccessful.
+</p>
+<p>
+“No savvy!” he cried, as Ned brushed past
+him and stood in the private hall.
+</p>
+<p>
+Ned paid no further attention to him, but
+entered the sitting room and at once advanced to
+the couch where the man lay. The figure on the
+couch did not move, but the Jap forced himself in
+the boy’s way with his cry of “no savvy!”
+</p>
+<p>
+“Opium?” Ned asked, pointing down to
+the man.
+</p>
+<p>
+“No savvy!”
+</p>
+<p>
+“Hit the pipe?” he asked, putting the question
+in a new way.
+</p>
+<p>
+“No savvy! No savvy!”
+</p>
+<p>
+“Dope, then?” Ned went on. “Tell me if
+this man has been doping himself into unconsciousness.
+Dope, eh?”
+</p>
+<p>
+Ned lifted his voice, half hoping that the
+man on the couch would show some signs of life,
+but there was no movement of the eyelids.
+</p>
+<p>
+“No savvy!” grunted the Jap.
+</p>
+<p>
+Ned took the servant by his shoulders,
+pushed him gently out of the room, and closed
+<span class='pagenum pncolor'><a id='page_87'></a>87</span>
+and locked the door, the key being in the lock
+on the inside.
+</p>
+<p>
+“No savvy! No savvy!”
+</p>
+<p>
+The words came through the thin panel of
+the door in quick succession for a minute and
+then silence. Again Ned advanced to the side
+of the couch and looked down upon the semi-unconscious
+man.
+</p>
+<p>
+It was clear to the boy that the fellow sensed
+what was taking place, but was too well satisfied
+with the drugged condition in which he lay
+to disturb his poise of mind by taking note of
+anything whatever. The figure of the fellow
+was dressed in expensive clothes of latest cut,
+but they were soiled, and even torn in places.
+</p>
+<p>
+The disreputable condition of the garments
+reminded Ned of a suit in which he had once
+been hauled through a briar patch and pulled
+into a pond at the hands, or horns, rather, of a
+village cow, assisted by a rope. His clothes, it
+is true, had not been expensive ones at the time
+of the occurrence, but the looks of the clothes
+the drugged man wore reminded him of the
+damage his cheaper ones had sustained.
+</p>
+<p>
+The face of the man on the couch was deadly
+pale, with the drawn look about the skin which
+comes of much familiarity with the drug made
+<span class='pagenum pncolor'><a id='page_88'></a>88</span>
+of the poppy. It was still an attractive face,
+even in its degradation, and the forehead was
+that of a capable man.
+</p>
+<p>
+Ned drew a chair to the side of the couch
+and sat down. Even if he should at that time
+succeed in attracting the attention of the man,
+the fellow was in no condition to answer the
+important questions he was there to ask.
+</p>
+<p>
+Presently the Jap, or some one else, came
+and rapped lightly on the door, and Ned opened
+it a trifle and looked out.
+</p>
+<p>
+“No savvy!” cried the Jap, repeating the
+words like a parrot, standing in the hall with
+many signs of fright on his yellow face.
+</p>
+<p>
+“All right!” Ned said, shutting the door in
+his face, “you don’t have to.”
+</p>
+<p>
+“I can’t blame him for thinking this a cheeky
+invasion,” Ned smiled, as he returned to his
+chair at the side of the couch. “It isn’t exactly
+the thing to walk into a man’s private
+room in this manner.”
+</p>
+<p>
+Ned had decided to sit by the side of the
+half conscious man until he returned to his full
+mentality. Questions now might produce only
+pipe dreams, for the imagination is rather too
+active under such circumstances.
+<span class='pagenum pncolor'><a id='page_89'></a>89</span>
+</p>
+<p>
+Five days before Ned had left the boys in a
+cup on the western slope of the Rocky Mountains,
+not far from the summit, after explaining
+to them that he was going to the city to investigate
+a clue connected with the murder of the
+man who had been found in the cavern. Leaving
+the aeroplane safely hidden at Missoula, he
+had traveled by rail to San Francisco.
+</p>
+<p>
+In his handbag on this trip were two seemingly
+unimportant articles—a piece of tape cut
+from the inner side of the collar of the dead
+man’s coat, and a small, odd-shaped key with the
+stem broken off so that it was only about an inch
+in length. The key had been the only article
+found in the dead man’s pockets. The strip
+of tape bore the name of a San Francisco tailor.
+</p>
+<p>
+The directory had assisted him in finding
+the tailor, and the tailor had informed him that
+the coat had been made for one Albert Lemon,
+whose address he gave. So here he was, in
+Lemon’s apartment, seeking information concerning
+the dead man, while Lemon, supposedly
+Lemon, lay in an opium daze on the couch.
+</p>
+<p>
+But Ned’s time, waiting for the man to come
+back to consciousness, was not all wasted. Moving
+carefully about the room, he found that the
+broken key fitted a writing desk which stood
+<span class='pagenum pncolor'><a id='page_90'></a>90</span>
+between two windows. The lock which it fitted,
+however, was not in good condition, for the bolt
+had been pried back, damaging the polished edge
+of the casing which held the socket. The desk
+contained nothing of importance, and Ned left
+it as he found it.
+</p>
+<p>
+Sitting there in the soft light of the room, he
+did not know whether the man on the couch
+was Albert Lemon or whether the man who had
+died in the cavern was Albert Lemon. He believed,
+however, that the outlaws he had encountered
+in the mountains, had murdered the
+man, and felt that the surest way to trace the
+crime to them was to find out why the man had
+joined them—why he was there in the tunnel
+back of the cupboard. This would be likely to
+bring out a motive for the deed.
+</p>
+<p>
+He did not, of course, know whether the dead
+man had stood as an enemy to the outlaws, or
+whether he had stood as a friend. But that
+could make no difference with the quest he was
+on. He believed that the outlaws were the men
+he had been instructed to hunt down, and knew
+that proof could be obtained only by an intimate
+knowledge of their associations, their ways,
+their motives. The friends of the dead man he
+thought, would know something about them,
+<span class='pagenum pncolor'><a id='page_91'></a>91</span>
+perhaps be able to place them in the circle in
+which they lived when not in the hills.
+</p>
+<p>
+In work of this kind it is the first task of an
+investigator to “place” the man he is pursuing.
+The burglar is as good as taken when he is traced
+back to those he associates with in his hours of
+leisure. In the absence of a clue pointing to a
+person, the investigator busies himself in finding
+a motive. Ned believed that he now had the
+personal clue. The motive would place the
+proof in his hands.
+</p>
+<p>
+So his Secret Service work for the government
+was leading him into the investigation of
+a murder mystery. He smiled as he held up the
+key and wondered if the facts when discovered
+would bear out the suspicions in his mind.
+Again he asked himself the question:
+</p>
+<p>
+“Is this Albert Lemon, or was the dead man
+Albert Lemon?”
+</p>
+<p>
+After a long time the man on the couch
+opened his eyes and looked about the room.
+His glance rested for an instant on the figure in
+the chair at his side, but the fact of its being
+there did not appear to surprise him in the least.
+</p>
+<p>
+“Jap!” he called faintly.
+</p>
+<p>
+There was a sound at the door, but it was
+still locked, and the servant was unable to obey
+the summons.
+<span class='pagenum pncolor'><a id='page_92'></a>92</span>
+</p>
+<p>
+“Bring me a pipe!” were the next words.
+</p>
+<p>
+The Jap clamored at the door, but did not
+gain admission. The racket seemed to disturb
+the man not at all.
+</p>
+<p>
+“I think,” Ned said, “that you have had
+all the dope you need to-night. Besides, I want
+you to answer a few questions.”
+</p>
+<p>
+“Perhaps I have,” the man said, “but, supposing
+that to be the case, where do you come in?
+You are a new one on me, and I hope you won’t
+flop out of a window or go up through the roof, as
+some of the others have done. I want to have
+congenial company to-night. Who are you?”
+</p>
+<p>
+“Ned Nestor,” was the quiet reply.
+</p>
+<p>
+“So,” said the man on the couch. “I’ve
+heard of you—read about you and the Canal
+Zone in the newspapers. But you’re only a kid.
+What about that?”
+</p>
+<p>
+“I can’t help being young,” laughed Ned.
+“Anyway, that is a fault I’ll soon get over. We
+all have it at first.”
+</p>
+<p>
+“And get over it too quickly,” said the other,
+with a sigh. “Well, what do you want here?”
+</p>
+<p>
+“Are you Albert Lemon?” asked Ned abruptly.
+</p>
+<p>
+“Yes,” was the reply, “I’m Albert Lemon.
+What about it?”
+<span class='pagenum pncolor'><a id='page_93'></a>93</span>
+</p>
+<p>
+The man was gaining mental strength every
+moment now, and seemed to sense the strange
+situation.
+</p>
+<p>
+“Stiles is your tailor?” the boy went on.
+</p>
+<p>
+“Look here,” said the other, rising to a sitting
+position and passing a shaking hand across
+his brow, as if to brush away the fancies of the
+poppy, “when you convince me that you have
+a laudable interest in my personal affairs I’ll be
+glad to answer your questions.”
+</p>
+<p>
+Ned took the strip of tape from his pocket
+and held it out to the man on the couch.
+</p>
+<p>
+“Do you recognize that?” he asked.
+</p>
+<p>
+Lemon nodded coolly, but a look of wonder
+and alarm was growing in his bloodshot eyes,
+and his jaw dropped a trifle.
+</p>
+<p>
+“I still lack the proof of laudable interest,”
+he said, with a twisting of the face intended for
+a smile.
+</p>
+<p>
+“Answer the question,” Ned replied, “and
+I’ll inform you of my interest in this article—and
+in you.”
+</p>
+<p>
+“Yes, I recognize it as the private mark of
+Stiles, my tailor,” Lemon answered, in a moment.
+“Where did you get it? If you insist
+on asking personal questions I must insist on
+the right to do the same thing.”
+<span class='pagenum pncolor'><a id='page_94'></a>94</span>
+</p>
+<p>
+“I cut this private mark,” Ned said, “from
+the collar of a coat found on the back of a dead
+man in Montana, somewhere near the main divide
+of the Rocky Mountains. Do you know
+how it came there?”
+</p>
+<p>
+“Yes and no,” was the reply.
+</p>
+<p>
+“Kindly answer the affirmative proposition
+first,” Ned said, with a smile.
+</p>
+<p>
+“Well,” said the other, “about three months
+ago an old college friend of mine, one Felix Emory,
+came to me from Boston. He was in bad
+with his people, and was out of money. I took
+him in here and tried to brace him up. I
+couldn’t do it. His moral stamina was gone.”
+</p>
+<p>
+Lemon paused a moment, and, with a deprecatory
+smile, pointed to an opium pipe which
+lay on the rug near the couch.
+</p>
+<p>
+“I understand,” Ned said.
+</p>
+<p>
+“I fed him, and clothed him, and introduced
+him at the club, and gave him every chance in
+the world to get a brace, but he fought me off.
+All he cared for was a pipe and a pill and a place
+to sleep it off.”
+</p>
+<p>
+“And so you gave him up as a bad proposition?”
+asked Ned.
+</p>
+<p>
+“Not exactly. He wanted to go to the mountains
+on a hunting trip. Well, I thought it would
+<span class='pagenum pncolor'><a id='page_95'></a>95</span>
+benefit his health, so I rigged up an outfit for
+his use and let him go. You say the man was
+dead?”
+</p>
+<p>
+“Quite dead,” Ned replied.
+</p>
+<p>
+“Too much poppy, I presume?” Lemon
+asked with an ashamed smile.
+</p>
+<p>
+“Too much steel,” Ned answered, sharply.
+</p>
+<p>
+Lemon stared at the boy for an instant, his
+eyes more anxious than ever, and arose shakingly
+to his feet.
+</p>
+<p>
+“Do you mean that he was murdered?” he
+asked.
+</p>
+<p>
+Ned nodded.
+</p>
+<p>
+“Where?” was the next question.
+</p>
+<p>
+“I found the body in a cavern on the western
+slope of the Rockies,” was the reply. “He had
+been dead only a few hours.”
+</p>
+<p>
+Albert Lemon maintained a thoughtful silence
+for a time, during which Ned eyed his
+changing expression keenly.
+</p>
+<p>
+“And what do you wish me to do about it?”
+he then asked.
+</p>
+<p>
+“A crime has been committed,” Ned replied,
+“and it seems to me that you ought to do all in
+your power to assist in bringing the criminal to
+punishment.”
+</p>
+<p>
+“Granted, sir. Tell me what to do.”
+<span class='pagenum pncolor'><a id='page_96'></a>96</span>
+</p>
+<p>
+“First, tell me about the men your friend
+went away with.”
+</p>
+<p>
+“That brings me to the negative proposition,”
+the other answered. “I have told you
+how Felix came by my coat, but I can’t tell you
+whether the man the coat was found on was
+Felix. You must see that for yourself. He
+might have given the garment away, or he might
+have sold it in the city to get money for opium.
+In short, the coat might have been on the body
+of a man I never saw.”
+</p>
+<p>
+“Then you can’t tell me who Emory went
+away with?” asked Ned.
+</p>
+<p>
+“Certainly not,” was the reply. “I don’t
+know whether he went away at all or not.”
+</p>
+<p>
+This was disappointing, but Ned had one
+more lever with which the man’s indifference
+might be lifted, he thought. Before speaking
+again Lemon arose and turned the key in the
+lock of the door, against which the servant was
+still pounding. The Jap entered and stood by
+the door, looking intently at Ned.
+</p>
+<p>
+“When you gave him the suit of clothes he
+went away in,” the boy went on, shifting his
+position so that both men would be under his
+eyes, “what articles, if any, remained in the
+pockets?”
+<span class='pagenum pncolor'><a id='page_97'></a>97</span>
+</p>
+<p>
+“Not a thing,” was the reply. “I looked
+out for that.”
+</p>
+<p>
+“Then anything discovered in the pockets
+of the dead man,” Ned said, taking the key
+from his pocket and toying carelessly with it,
+“must have belonged to him?”
+</p>
+<p>
+Ned saw Lemon give a quick start at sight
+of the key. The Jap advanced a step as if to
+get a closer view of it. Then both men turned
+their eyes for an instant to the broken lock of
+the writing desk. Ned had gained his point.
+The men recognized the key.
+</p>
+<p>
+“Where is the body you speak of?” Lemon
+asked, presently.
+</p>
+<p>
+“Buried near the cavern in the mountains,”
+was the reply.
+</p>
+<p>
+“Perhaps you can give me a description of
+the body,” Lemon said. “I might be able to
+say, then, whether the man was Felix.”
+</p>
+<p>
+“Look in the mirror,” Ned replied, “and
+you will see there a fairly good representation of
+the dead man. About the same in height, in
+size, and, yes, in feature.”
+</p>
+<p>
+“Then it must have been Felix,” the other
+said. “His remarkable resemblance to myself has
+often been remarked. Poor fellow! I’m sorry
+that his end should come in so ghastly a form.”
+<span class='pagenum pncolor'><a id='page_98'></a>98</span>
+</p>
+<p>
+There was a short silence, during which Lemon’s
+eyes flitted from the key in Ned’s fingers to
+the writing desk.
+</p>
+<p>
+“I said a moment ago,” he observed then,
+“that I searched the pockets of the clothes
+before I gave them to him, or words to that
+effect. I remember now that I ordered Jap to
+do it. Did you obey orders?” he asked, turning
+to the servant.
+</p>
+<p>
+Ned saw the Jap give a quick start, then
+regain control of himself. Lemon, too, looked
+crestfallen for a moment, then addressed the
+Jap in another tongue.
+</p>
+<p>
+“I was talking in English,” he said, “and
+forgot for the moment that he would not understand
+me.”
+</p>
+<p>
+There followed a short conversation between
+the two, and then Lemon announced that the
+Jap had forgotten to look in the pockets of the
+clothes. Ned ignored the explanation and put
+the key in his pocket. He knew now that the
+Jap could understand English, and also that the
+key belonged to Albert Lemon, alive or dead.

+Lemon arose and, going to a table, secured
+a tobacco pouch and a book of cigaret papers.
+As he rolled a cigaret Ned observed that the
+middle finger of his left hand carried, just
+below the nail, a blue spot, as if he had been using
+a typewriter since cleaning his hands. Ned noticed
+it particularly, as he himself used a double
+keyboard machine and usually smutted that
+finger on the ribbon when he rolled the platen.
+</p>
+<p>
+“Well,” Lemon said, “I’ll have to ask you
+to excuse me now. I’ve been off on a long
+country tramp. You see how mussed up I am.
+I think I crawled through briar patches and wire
+fences and fell into cow ponds.”
+</p>
+<p>
+Ned turned away without a word, with plenty
+of food for thought in his mind.

+<h2><span class='pagenum pncolor'><a id='page_100'></a>100</span><a name='chVIII' id='chVIII'></a>CHAPTER VIII.—FATE OF THE STEAK A LA BRIGAND.</h2>
+<p>
+Jimmie lay stretched at full length under one
+of the discolored shelter tents in a little cup in
+the heart of the Rocky Mountains. Frank and
+Pat and Jack were moving restlessly about, looking
+up at the blue sky expectantly. Ned had
+not returned from his trip to San Francisco,
+and the boys were anxious as to his safety.
+</p>
+<p>
+“He should have taken me with him,” Jimmie
+drawled, presently, when Frank threw himself
+down by the tent. “Then he’d have been
+all right.”
+</p>
+<p>
+“It is a wonder that he got along in the
+world at all before he fell under your protecting
+care,” Frank replied, with a grin.
+</p>
+<p>
+“Oh, he managed in some way,” Jimmie
+answered, “but he never got up in the world until
+he took me into partnership,” with a wink
+at his chum.
+</p>
+<p>
+“He’s been up in the world since then, all
+right,” Frank said, suggestively.
+<span class='pagenum pncolor'><a id='page_101'></a>101</span>
+</p>
+<p>
+“Too high up,” Jimmie grinned. “Too high
+up for me, anyway. I thought I’d die up there,
+on the night of the fire.”
+</p>
+<p>
+“In all the history of air navigation,” Frank
+observed, soberly, “there was never a trip like
+that. When I think of the quick start, and the
+wind and the rain, the whole thing seems like a
+dream. How did he ever do it?”
+</p>
+<p>
+“I don’t know,” Jimmie replied. “He
+boosted me into the seat, and the next I knew
+we were off, an’ the fire was dropping away from
+us, an’ the mountains were growing smaller, an’
+the peaks looked like warts on the world. I
+felt like I was fallin’ over the edge of somethin’.”
+</p>
+<p>
+“And the wind?” questioned Frank. “Didn’t
+it take your breath away?”
+</p>
+<p>
+“Wind, nothin’,” the boy said, scornfully.
+“There wasn’t any wind where we were. We
+went along with it. It was like sailin’ on a swift
+stream. Ned tuned the engine up to keep
+steerway, an’ shut his teeth. Then, in half a
+minute, we were above the clouds, an’ the moon
+an’ stars were askin’ what we were doin’ up
+there.”
+</p>
+<p>
+“You’re saying it well,” Pat said, joining
+the little group. “If you were going so merrily
+before the wind, why did he want steerway?”
+<span class='pagenum pncolor'><a id='page_102'></a>102</span>
+</p>
+<p>
+“You don’t know much about the atmosphere,”
+laughed Frank, answering for Jimmie.
+“If you did, you’d know that the air blanket of
+the earth is a good deal like a river. It has eddies,
+and currents, and ripples, and holes, too.”
+</p>
+<p>
+“You’re good, too!” exclaimed Pat. “Holes
+in the air is about the best I ever heard!”
+</p>
+<p>
+“Of course there are holes in the air,” Frank
+replied, with the air of one imparting valuable
+information, “especially when there are fires beneath.
+And, let me tell you this, you old red-head,”
+he added, with an exasperating grin,
+“when the air, driven swiftly by the wind, or
+what we call the wind, comes to mountain peaks,
+and tall trees, and sky-scrapers, it just backs up,
+just the same as water does when it comes to a
+dam, or any obstruction.”
+</p>
+<p>
+“Go it!” Pat cried. “Make it a good one!
+Where does this air go when it backs up?”
+</p>
+<p>
+“It just hunches up,” Frank replied, gravely,
+“and checks the flow back of it, and then eddies
+and swirls away, fit to twist an aeroplane into
+kindling wood.”
+</p>
+<p>
+“Of course,” broke in Jimmie. “I’ve often
+read of aeroplanes dropping a thousand feet into
+holes in the air, and of their being swept against
+tall trees and buildings by eddies. It takes a
+<span class='pagenum pncolor'><a id='page_103'></a>103</span>
+cool head to run an air machine in a storm of
+wind, and that is where Ned won out.”
+</p>
+<p>
+“If he hadn’t kept the aeroplane going with
+the wind at full speed,” Frank added, “he would
+have been in a wreck the first half mile.”
+</p>
+<p>
+“The more I learn about the atmosphere,”
+Pat said, “the less I like it. When you get me
+up in an aeroplane, just send word to the folks
+that I’m tired of life.”
+</p>
+<p>
+“Ned ought to have a Carnegie medal for
+what he did that night,” Jack remarked, “and
+I’m going to speak to father about it when I get
+home.”
+</p>
+<p>
+“There is no doubt that he ought to have
+one,” Frank said, “but the men who really deserve
+Carnegie medals never get them.”
+</p>
+<p>
+“You’re an anarchist!” roared Pat.
+</p>
+<p>
+“All right,” was the sober reply, “but if I
+had the giving out of the medals I’d present
+them to men who work twelve hours a day and
+provide for families of eight on nine dollars a
+week—the men who never get rested, and who
+never have enough to eat. They are the ones
+who ought to have the medals.”
+</p>
+<p>
+“Most of them would sell the medals,” Jack
+said, cynically.
+<span class='pagenum pncolor'><a id='page_104'></a>104</span>
+</p>
+<p>
+“Well,” Frank replied, “I shouldn’t blame
+them if they did. I’d rather have a porterhouse
+steak in the interior than a piece of bronze on
+the outside.”
+</p>
+<p>
+“Don’t talk about porterhouse steak!” pleaded
+Jimmie.
+</p>
+<p>
+“Hungry, little man?” asked Pat.
+</p>
+<p>
+“Hungry! I’m like one of the men Frank
+has been telling about. I never get rested,
+never have enough to eat.”
+</p>
+<p>
+The boys fell upon Jimmie and rolled him
+out of the tent.
+</p>
+<p>
+“You get busy with fuel,” Pat said, after
+they had given him plenty of “movements,”
+“and I’ll cook a steak à la brigand.”
+</p>
+<p>
+“We ain’t got no steak,” complained Jimmie.
+</p>
+<p>
+“We’ve got potatoes, and bacon, and onions,”
+Pat said, “and canned beefsteak. You just
+watch me. I used to cook steak à la brigand in
+the Philippines.”
+</p>
+<p>
+“Get busy, then,” Jimmie said, “and Jack
+will help get the green wood.”
+</p>
+<p>
+“If you bring green wood here for me to
+cook with, I’ll roast you over it,” Pat said.
+“You get a lot of good dry wood that will make
+coals, and I’ll show you how to broil a steak à
+la brigand.”
+<span class='pagenum pncolor'><a id='page_105'></a>105</span>
+</p>
+<p>
+“Why do you call it a brigand steak?” asked
+Jimmie.
+</p>
+<p>
+“Because it takes a red-headed brigand to
+cook it,” suggested Jack, dodging out of Pat’s
+reach.
+</p>
+<p>
+“Never you mind the name,” Pat replied.
+“Get the dry wood and I’ll broil a steak that will
+melt in the mouth.”
+</p>
+<p>
+“That old canned stuff?” asked Frank.
+</p>
+<p>
+“Get the wood,” ordered Pat, “and I’ll show
+you.”
+</p>
+<p>
+There were a few dead trees—the sole reminders
+of a former forest fire in that green valley—close
+at hand, and the wood was soon gathered
+and placed in a great pile near two rocks
+which Pat had rolled to within a yard of each
+other.
+</p>
+<p>
+“Here!” Jack called out, as Pat transferred
+the whole supply to the space between the
+stones, “there’s enough fuel there for a week’s
+cooking. Quit it!”
+</p>
+<p>
+“My son,” Pat replied, with a provoking air
+of patronage, “what you don’t know about
+broiling a steak à la brigand would make a congressional
+library.”
+</p>
+<p>
+While the wood was burning down to coals,
+Pat cut a green slip about an inch in diameter
+at the bottom and peeled and smoothed it nicely.
+<span class='pagenum pncolor'><a id='page_106'></a>106</span>
+</p>
+<p>
+“Is that to be used to enforce the eating of
+the steak?” asked Frank, winking at the others.
+</p>
+<p>
+“To keep you from gorging yourselves,” Pat
+replied, going on with his work.
+</p>
+<p>
+In a short time he had the potatoes cut into
+half-inch slices. Jack had peeled them and, following
+directions with many grins, had also cut
+a round hole an inch in size in the middle of each
+slice.
+</p>
+<p>
+“He’s going to wear ’em around his neck,
+like beads,” Jimmie suggested, looking carefully
+over the heaped-up dish.
+</p>
+<p>
+The bacon was now sliced thin, as were the
+onions, and in the center of each slice a round
+hole was made. Then Pat opened a couple of
+tins of beefsteak—so called by the packers—and
+cut a hole in the middle of each slice.
+Then he strung a slice of potato on the spit,
+then a slice of bacon, then a slice of onion, then
+a slice of beef, until there was nearly a yard
+of provisions.
+</p>
+<p>
+“I begin to feel hungrier than ever!”
+</p>
+<p>
+Jimmie was dancing around the fire as Pat
+turned the spit. There were only coals now,
+and Pat kept the toothsome collection turning
+slowly, so as to broil without scorching. The
+smell of the cooking bacon and onions set the
+<span class='pagenum pncolor'><a id='page_107'></a>107</span>
+boys to getting out the tin plates and making
+the coffee.
+</p>
+<p>
+The sun, which had been shining fiercely all
+day, now seemed to be working his way through
+a mist. The atmosphere appeared to be tinted
+with the yellow haze one sees in the northern
+states in autumn.
+</p>
+<p>
+As the boys were keeping watch for Ned and
+the aeroplane, they noticed the change in atmospheric
+conditions, but attributed it to the
+rising vapor brought out by the heat of the sun.
+</p>
+<p>
+“Say,” Jimmie said, presently, “I smell
+smoke. I wonder if there’s goin’ to be another
+forest blaze here?”
+</p>
+<p>
+“Of course you smell smoke,” Jack said,
+watching the broiling supper. “We’re cooking
+a steak à la brigand, ain’t we?”
+</p>
+<p>
+“Smells like burnin’ leaves,” Jimmie insisted.
+</p>
+<p>
+“More like onions,” Pat observed.
+</p>
+<p>
+The boys crouched about the fire for some
+moments longer and then Jimmie arose and began
+to climb the wall of the cup to the west.
+</p>
+<p>
+“I’m goin’ to see about this,” he said.
+</p>
+<p>
+Frank laid a hand on his arm.
+</p>
+<p>
+“You wait a minute,” he said. “You can’t
+climb that slope in less than half an hour, and
+<span class='pagenum pncolor'><a id='page_108'></a>108</span>
+Ned will be here before that. Look! He’s
+coming now, like the wind!”
+</p>
+<p>
+The aeroplane, high up in the hazy sky, was
+indeed making good progress toward the little
+cup in the mountain side. While the boys
+looked they saw it shift away to the west, whirl
+back to the east, dart off to the north and back
+again.
+</p>
+<p>
+“He’s huntin’ for us,” Jimmie said.
+</p>
+<p>
+“He’s investigating!” Frank cut in.
+</p>
+<p>
+“Investigating what?” Pat demanded.
+“He’s smelling of this steak à la brigand and is
+hunting for it. Let be. He’ll find us.”
+</p>
+<p>
+The sky was growing more uncertain every
+minute, and puffs of smoke were seen out in the
+west, over the rim of the cup.
+</p>
+<p>
+“The world is on fire, I tell you!” Jimmie
+cried, presently. “That’s what Ned is shiftin’
+about for. If the blaze wasn’t high up on the
+mountains we couldn’t see the columns of smoke
+over the rim of the valley.”
+</p>
+<p>
+“Well,” Pat observed, “the fire can’t get in
+here. Nothing to burn.”
+</p>
+<p>
+“It can fill the cup with hot air and scorch
+us to death,” Frank said, uneasily. “I think
+we’d better be looking about for a place to crawl
+into.”
+<span class='pagenum pncolor'><a id='page_109'></a>109</span>
+</p>
+<p>
+“Wait until Ned comes,” Jimmie suggested.
+“He’ll know what to do.”
+</p>
+<p>
+The aeroplane acted badly in the currents
+caused by the burning forest, but Ned finally
+managed to bring it down in the valley. The
+boys gathered about him, all excitement, and
+the steak à la brigand was for the moment forgotten
+in the joy at the return of the patrol
+leader and the anxiety to learn something of
+conditions out in the woods.
+</p>
+<p>
+“It’s going to be a great conflagration,” Ned
+said, “but I think the aeroplane will be safe
+here. The whole slope is on fire.”
+</p>
+<p>
+“I wouldn’t take chances on leaving it here,”
+Frank advised. “I’d jump over the divide with
+it.”
+</p>
+<p>
+“I have been in the air three hours now,”
+Ned replied, “and must have a rest. Besides,
+we must remain where we can, if necessary, help
+head off the flames. That is what we are here
+for, remember.”
+</p>
+<p>
+“Not to fight fires,” corrected Frank, “but
+to find out who sets them.”
+</p>
+<p>
+“Anyhow,” Ned replied, “we must fight the
+fire, if it gives us a chance, now that we are here.
+Now, what do you think that is?” he added,
+<span class='pagenum pncolor'><a id='page_110'></a>110</span>
+as a chorus of howls and cries came up from the
+slope on the west.
+</p>
+<p>
+“Sounds like a country circus!” Jimmie
+laughed.
+</p>
+<p>
+“That is just what it is!” Ned exclaimed.
+“Here! Help me roll the aeroplane into that
+nook, where it won’t be trampled into splinters.
+Now you boys get behind it, and I’ll get in front.
+Whatever you see or hear, don’t shoot unless
+you are actually attacked.”
+</p>
+<p>
+The boys obeyed the commands without a
+word of comment, well knowing what was coming
+next. A breeze was sliding up the slope,
+bringing with it flying masses of smoke. Presently
+birds began to stagger through the heavy
+atmosphere, flying low, almost within reaching
+distance, as they had fled long before the mounting
+flames and were exhausted.
+</p>
+<p>
+“I wish this would let up a moment,” Pat
+said, “long enough for us to reach that steak
+à la brigand. It must be about done by this
+time.”
+</p>
+<p>
+“I’ll go an’ get it,” volunteered Jimmie.
+“An’ eat most of it on the way back.”
+</p>
+<p>
+“Then bring the coffee,” cried Jack.
+</p>
+<p>
+“Why can’t we all go out there and eat?”
+asked Frank.
+<span class='pagenum pncolor'><a id='page_111'></a>111</span>
+</p>
+<p>
+The boys were about starting with a rush
+when Ned caught two of them by the arm and
+stopped the others by a quick call. Through the
+smoke and the hot air on the rim of the cup, a
+great head, a head neither white nor black, but
+grizzly, was seen. Then a deer bounded over
+and crouched down in the valley. Next two
+mountain lions raced over the lip of the valley
+and halted growling, within a few yards of the
+boys.
+</p>
+<p>
+“There goes our steak à la brigand!” Jimmie
+cried, as the rush of frightened animals
+showed under the smoke. “I’ll eat one of them
+deer to pay for this,” he added.
+</p>
+<p>
+“You’ll be lucky if one of these wild animals
+doesn’t eat you,” Jack said. “How would you
+like to be back in little old Washington Square
+just now?”
+</p>
+<p>
+“Forget it!” was the boy’s only reply.
+</p>
+<p>
+“Will the fire get here?” Frank asked of
+Ned, as the wild creatures of the forest poured
+into the valley, regardless of the presence of the
+boys, unmindful of the proximity of each other.
+</p>
+<p>
+“I don’t think the flames will come into the
+cup,” Ned replied, “but if the smoke settles
+here we shall have a hot time of it.”
+<span class='pagenum pncolor'><a id='page_112'></a>112</span>
+</p>
+<p>
+“Huh!” Jimmie cried. “The whole valley
+is full of mountain lions, an’ bears, an’ deer, an’
+snakes, an’ rabbits. There ain’t no room for
+any smoke!”
+</p>
+<p>
+Then the smoke rolled away for an instant,
+showing a sun as red as a piece of molten iron;
+showing, too, a huddle of forest animals crowding
+together in the center of the valley. In
+their terror of the fire they had forgotten to be
+afraid of mankind—of each other!
+</p>
+<h2><span class='pagenum pncolor'><a id='page_113'></a>113</span><a name='chIX' id='chIX'></a>CHAPTER IX.—THE CHAOS OF A BURNING WORLD.</h2>
+<p>
+That was a day long to be remembered in the
+Great Northwest. It is true that the destruction
+of life and property at that time by no means
+equaled the ruin wrought by the forest fires of
+August, 1910, but the conflagration was serious
+in its final results for all that.
+</p>
+<p>
+In August of the previous year half a hundred
+persons lost their lives in the fierce fires
+which swept over portions of Idaho and Montana,
+and more than six billion feet of lumber
+were destroyed. At that time wild animals
+raced into the log houses of settlers in order to
+escape the flames. In one instance, placed on
+record by a forester, a mountain lion actually
+sought shelter under a bed.
+</p>
+<p>
+In that case, too, the fire virtually held its
+ruthless way until it burned itself out, as there
+were no trails, no telephones, no provisions for
+the fire fighters. The men of the forest patrol were
+each guarding a hundred thousand acres. In the
+more civilized countries of Europe, a thousand
+acres is considered a large district for one man.
+<span class='pagenum pncolor'><a id='page_114'></a>114</span>
+</p>
+<p>
+It was hot and close in the odd little valley
+on the mountain side. There seemed a premonition
+of greater danger in the very air—the
+lifeless air which seemed to dry the lungs beyond
+power of action. The wind, coming over
+the blazing forests, struck hot upon the face and
+scorched the lips, while the acrid smoke filled
+the eyes, the ears, the nostrils.
+</p>
+<p>
+It seemed to Ned that everything east of the
+Kootenai river must be on fire. Now and then,
+drawn by some wayward current of air, the
+thick smoke lifted in the little cup-like valley,
+and the cowering wild animals could be seen,
+huddling together in the terror of the time, deer
+no longer afraid of lion or bear, lion and bear
+forgetting to mark their prey.
+</p>
+<p>
+Finally, anxious to know the extent of the
+disaster, so far as it might be judged by a personal
+view of the country west of the valley,
+Ned left the boys in charge of the aeroplane and
+crept toward the rim of the cup. Jimmie saw
+him leaving and started on after him, but Jack
+drew him back.
+</p>
+<p>
+“Let him go alone, for once,” Jack said,
+“he’s only going to find out where this menagerie
+of wild animals comes from.”
+<span class='pagenum pncolor'><a id='page_115'></a>115</span>
+</p>
+<p>
+Jimmie settled sullenly back by Jack’s side,
+resolved to break away at the first opportunity
+and follow the patrol leader.
+</p>
+<p>
+When Ned gained the elevation he sought,
+the procession of wild animals had come to an
+end, although birds, frightened and singed by
+the flames, were calling from the sky. Everywhere
+rolled billows of smoke, blown on ahead
+of the line of fire and in a measure concealing
+its fatal advance.
+</p>
+<p>
+Now and then, however, a spurt of hot wind
+came over the burned waste and lifted the curtain
+for an instant. Then the boy saw that the
+fire was crawling up the slope, not racing as
+it had earlier in the day, but moving steadily,
+sweeping the earth of the undergrowth, but
+leaving many large trees.
+</p>
+<p>
+The danger was decreasing there, but lower
+down the flames were consuming everything in
+their path, eating down great trees and leaving
+fiery, straggling columns to consume them to
+ashes. Ned thanked his stars that the growths
+on the slope were not dense enough to foster
+such a blaze as that which burned below.
+</p>
+<p>
+It has been stated by those who know that
+ordinary care would have prevented most of the
+devastating forest fires which have raged in the
+<span class='pagenum pncolor'><a id='page_116'></a>116</span>
+Northwest. Experts claim that forests should
+be burned over under careful supervision, every
+three or four years. This, they say, will prevent
+the accumulation of inflammable material such
+as caused the terrible losses of August, 1910.
+</p>
+<p>
+Ned saw at once the expediency of the proposed
+remedy. He knew that resinous spines,
+steeped in the drippings of pitch and turp from
+the overhead branches, had lain many inches
+deep around the trunks of the trees, beneath
+fallen boles, and at the roots of the undergrowth.
+This accumulation made the extinguishing of
+forest fires impossible. He understood that the
+government had virtually provided for what
+followed by permitting this material to accumulate
+year after year.
+</p>
+<p>
+It is declared by foresters and others who
+strove to check that wall of fire that it advanced
+at the rate of a mile a minute between the Kootenai
+river and the foothills. Below where Ned
+lay was a burning furnace. It was so hot that
+he dare not lift his face a second time, and so he
+moved back to the aeroplane, which he found
+still safe from the flames, and the wild creatures
+crouching in the center of the valley.
+</p>
+<p>
+“What are the prospects?” Frank asked,
+speaking with his lips close to the ear of the
+<span class='pagenum pncolor'><a id='page_117'></a>117</span>
+patrol leader, for the roaring of the flames rendered
+ordinary conversation difficult.
+</p>
+<p>
+“There is safety here,” Ned replied, “but
+everything to the west seems to be burning.”
+</p>
+<p>
+“Gee!” Jimmie cried, looking Ned in the
+face, “how would you like to meet a friend
+with a basket of ice?”
+</p>
+<p>
+“Ice wouldn’t last long here,” Frank said.
+</p>
+<p>
+“Not if I got hold of it!” Jimmie grunted.
+</p>
+<p>
+As the line of fire came nearer to the top of
+the slope the air grew hotter, the smoke denser
+and more stifling. Pat remembered that a pail
+of water from a spring had been brought to the
+vicinity of the aeroplane soon after Ned landed,
+and the boys wet their handkerchiefs and bound
+them over their eyes and mouths.
+</p>
+<p>
+As the heat increased the wild creatures
+crowding together ominously. When a feeble
+beast was trampled by a stronger one, or when
+a rattler struck at the leg of a bear or deer, there
+was a cry of pain and a quick milling of the pack.
+</p>
+<p>
+“If this doesn’t end soon,” Frank shouted
+to Ned through his handkerchief, “there will be
+a stampede here. Then it will be all off for us.”
+</p>
+<p>
+Ned looked around the little circle before
+replying. The boys certainly looked like “white
+caps” with their sheeted faces.
+<span class='pagenum pncolor'><a id='page_118'></a>118</span>
+</p>
+<p>
+“We’ll have to wait and hope for the best,”
+he said. “If the animals come this way, we
+must stop them, so far as we are able, with our
+guns and electric flashlights.”
+</p>
+<p>
+Presently night fell, and the wind quieted a
+little at the setting of the sun. In a short time
+the clouds rolled away in sullen, threatening
+groups, and the stars looked down on the forest
+tragedy. Later, there would be moonlight.
+</p>
+<p>
+“I wonder if all the world is burned, except
+just this mountain?” Jimmie asked, taking the
+handkerchief from his face and wiping the smoke
+out of his inflamed eyes. “It looks that way.”
+</p>
+<p>
+“There seems to be enough left to hold a lot
+of heat,” Jack said. “I don’t believe it will
+ever be cool again.”
+</p>
+<p>
+“If we’d only saved that brigand steak!”
+wailed Jimmie.
+</p>
+<p>
+With the half light and the cooler air there
+came a commotion in the mass of forest creatures
+in the center of the valley. It was night now,
+and they seemed to feel the mounting of their
+wild instincts to be up and away on the hunt.
+</p>
+<p>
+Under the stars, one by one, they slunk away,
+bears and mountain lions turning sullenly toward
+the lesser beasts, but still too terrified by
+what they had passed through to feel the pangs
+<span class='pagenum pncolor'><a id='page_119'></a>119</span>
+of hunger. In half an hour the menagerie had
+vanished, some to the mountain, some over the
+slopes to the north and south. The boys drew
+long breaths of relief when the shambling figure
+of the last bear disappeared.
+</p>
+<p>
+Once Jack drew his gun on a fat old buck
+who seemed desirous of investigating the aeroplane,
+but Ned saw the action and checked the
+slaughter.
+</p>
+<p>
+“Let him alone,” he said. “He’s lived
+through this hell on earth, so give him one more
+chance.”
+</p>
+<p>
+The boys now began gathering up their scattered
+utensils, restaking the tents, and preparing
+supper. Jimmie proposed another brigand steak,
+but Pat insisted that he never wanted to get near
+enough to a fire to cook again, so they made an
+indifferent meal of biscuit and tinned pork and
+beans, not even going to the trouble to boil coffee.
+</p>
+<p>
+While they were eating a gunshot came from
+the east, followed by the challenge of a chanticleer.
+</p>
+<p>
+“What do you know about that?” demanded
+Jimmie.
+</p>
+<p>
+“I suppose,” Jack complained, “that we’ve
+been eating a picked-up supper within a few
+rods of a farmhouse, or cattle ranch!”
+<span class='pagenum pncolor'><a id='page_120'></a>120</span>
+</p>
+<p>
+“You might pry open some of the rocks
+back there,” Pat observed, with sarcasm, “and
+see if you can find the house you speak of. It
+was a human throat that crow came from.”
+</p>
+<p>
+“Sure it was!” cried Jimmie. “It was a
+Boy Scout call. Now just see me get him to
+talking.”
+</p>
+<p>
+“What’s a Rooster patrol chap doing here!”
+asked Jack. “I guess we are all having bad
+dreams.”
+</p>
+<p>
+Jimmie did not reply. Instead he put his
+hands to his throat and in a second a long snarling
+wolf cry came forth, rising into a shrill call,
+as if summoning a pack at a distance.
+</p>
+<p>
+“We’ll see what he knows about that,” the
+boy said.
+</p>
+<p>
+As they listened the challenge of the chanticleer
+came once more. This time Jack answered
+it with the growl of a black bear, which seemed
+to Frank to be a great improvement on his practice
+stunts in the Black Bear Patrol club rooms
+in New York.
+</p>
+<p>
+This odd exchange of greetings kept up for
+some moments, and then the figure of a boy
+of perhaps seventeen was seen in the uncertain
+light, making slow progress down the mountain,
+a short distance to the north. He carried a haversack
+<span class='pagenum pncolor'><a id='page_121'></a>121</span>
+on his shoulders and was dressed in the
+khaki uniform of the Boy Scouts of America.
+</p>
+<p>
+“He must be used to mountain work,” Jack
+remarked, as the boy leaped lightly from ledge
+to ledge and finally dropped into the valley. “I
+couldn’t do that, even in broad daylight, to save
+my life!”
+</p>
+<p>
+The stranger now advanced to the group of
+boys and gave them the half salute of the Boy
+Scouts, standing with right arm straight out
+from the shoulder, palm outward, three fingers
+standing vertical, the thumb crossing the palm
+to rest on the bent-in little finger. Ned replied
+with the full salute, which is made with the hand
+in the same attitude, only at the forehead.
+</p>
+<p>
+“What does the badge say?” demanded
+Jimmie.
+</p>
+<p>
+“Be prepared!” was the quick reply.
+</p>
+<p>
+“For what?” was the next question.
+</p>
+<p>
+“To assist those in distress.”
+</p>
+<p>
+“You’re all right,” Jimmie shouted. “What
+patrol?”
+</p>
+<p>
+“Chanticleer, Denver,” was the reply.
+</p>
+<p>
+“That accounts for the way you lighted
+down from the mountain,” laughed Ned.
+</p>
+<p>
+“I’ve got used to climbing in walking the
+streets of my home town,” smiled the other. “Is
+<span class='pagenum pncolor'><a id='page_122'></a>122</span>
+Ned Nestor here?” he added. “My name is
+Ernest Whipple; I’m looking for Mr. Ned Nestor.”
+</p>
+<p>
+“Here he is, the only good-looker in the
+bunch,” Jack laughed, pushing Ned forward.
+“What do you want of him?”
+</p>
+<p>
+“My father is connected with the Secret
+Service at Washington,” was the reply, “and
+he posted me as to what was going on here.
+Said I might come out and join the party, if
+Mr. Nestor would permit it. What do you say?”
+</p>
+<p>
+Of course the son of a man connected with
+the Secret Service at Washington—a man who
+undoubtedly knew all the plans of the men who
+had sent Ned into the Northwest—was not to
+be ignored, but at the same time Ernest would
+have been received into the party on the strength
+of his own engaging personality, his own frank
+manner. From the very first moment he was
+a favorite with all the boys.
+</p>
+<p>
+“You’re as welcome as the flowers of May!”
+Frank cried. “Been to supper?”
+</p>
+<p>
+“Last night!” grinned Ernest. “My haversack
+is empty—also my stomach. I had to
+take to the mountain in order to keep out of the
+fire, and couldn’t connect with a grub stake.”
+</p>
+<p>
+“Then there are fires east of the divide?”
+asked Ned.
+<span class='pagenum pncolor'><a id='page_123'></a>123</span>
+</p>
+<p>
+“Sure,” was the reply, “although they are
+nothing like the ones over here. The foresters
+are watching them, and there is little danger
+of their getting a big start.”
+</p>
+<p>
+“Where did you find foresters?” asked Ned,
+wondering if the men who had sneaked away
+from the cavern were not posing as foresters
+waiting to do further mischief.
+</p>
+<p>
+“They are in camp beyond the summit,”
+was the reply. “They told me they had patrols
+all through the lower levels.”
+</p>
+<p>
+Jack gave a description of the man who had
+visited the camp on the plateau, and was not at
+all surprised when Ernest identified the fellow
+as the apparent leader of the band of foresters
+he had passed on his way west.
+</p>
+<p>
+“I see that you don’t believe the men are
+foresters,” Ernest said, looking into Ned’s anxious
+face. “Well, to tell the truth, I doubt it
+myself. I heard some talk there that set me
+thinking, after I got away. There was a man
+there who had just arrived from San Francisco,
+they said, and he was doing a good deal of kicking
+about something that had been done, or
+hadn’t been done. I don’t know which.”
+</p>
+<p>
+“Can you describe the fellow?” asked Ned,
+a quick suspicion coming to his mind.
+<span class='pagenum pncolor'><a id='page_124'></a>124</span>
+</p>
+<p>
+“Of course I can,” was the reply, and the
+remainder of the answer gave an accurate word
+photograph of one Albert Lemon.
+</p>
+<p>
+Ned was thinking fast. How had Lemon
+reached the eastern side of the divide so quickly.
+He, himself, had traveled swiftly from San Francisco,
+leaving soon after his exit from the bachelor
+apartment where the strange and not entirely
+satisfactory interview had taken place.
+He had left the man who claimed to be Albert
+Lemon half dazed and weakened from the effects
+of opium—still weary from a long and exhausting
+journey, as shown by his clothing, and yet
+the fellow had beaten him out in the race to the
+mountains.
+</p>
+<p>
+Why? Certainly not to take charge of the
+body of his unfortunate friend, for the grave was
+not there, but in a little hollow away to the
+north and near the lake. His business seemed
+to lie with the outlaws who had, apparently,
+committed the crime. Why? Had the man
+been killed as the result of a conspiracy between
+the two interests?
+</p>
+<p>
+This point was worth looking into, for the
+motive for the deed might also prove to be the
+motive for other crimes—among them the burning
+of forests.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_125'></a>125</span><a name='chX' id='chX'></a>CHAPTER X.—CHASING THE MILKY WAY.</h2>
+<p>
+While the boys were exchanging experiences
+with Ernest Whipple, talking over Boy Scout
+matters and arranging for a sleeping place for
+the stranger, Ned was busy with his aeroplane.
+It had not suffered in the least from the heat
+and wind, and there was plenty of gasoline on
+hand for a journey which he was thinking of
+taking.
+</p>
+<p>
+“Where are we goin’ to-night?” Jimmie
+asked, finally, strolling over to the spot where
+the great bird lay.
+</p>
+<p>
+“As the wind is right,” Ned laughed, “I
+thought I’d take a sail over the divide and see
+what the alleged foresters are up to.”
+</p>
+<p>
+“All right,” the boy said, “just wait until
+I get a big blanket to wrap up in and I’ll go with
+you.”
+</p>
+<p>
+Ned smiled at the determination of the lad
+to keep close to his side. He knew that Jimmie
+dreaded the very idea of leaving the solid
+earth that night, still he found him willing to
+<span class='pagenum pncolor'><a id='page_126'></a>126</span>
+make the ascent merely for the sake of being in
+his company.
+</p>
+<p>
+“All right, kid,” he said. “You may go if
+you want to, but it may be morning before we
+get back to camp.”
+</p>
+<p>
+“You can’t remain in the air all that time,”
+Jimmie said.
+</p>
+<p>
+“I am fully aware of that,” Ned replied,
+“but I can drop down over on the other side
+and rest and tinker with the machine—if she
+doesn’t work just right.”
+</p>
+<p>
+“You haven’t got gasoline enough,” urged
+Jimmie, who would have argued Ned out of the
+notion of the night flight if possible, but who
+was determined to go with him if he went.
+</p>
+<p>
+“The first thing I do,” Ned replied, “will
+be to fly over the Great Northern right of way
+and fill up with gasoline. Besides filling the
+tanks, I shall carry a lot away in an aluminum
+keg I have provided for that purpose.”
+</p>
+<p>
+“Well,” Jimmie said, with a tired sigh, “I
+should think you’d been through enough to-day
+and to-night, without goin’ off in the dark, but
+I’m goin’ if you do.”
+</p>
+<p>
+After talking with the others regarding his
+intentions, and warning them to keep a sharp
+lookout during his absence, Ned assisted Jimmie
+<span class='pagenum pncolor'><a id='page_127'></a>127</span>
+to his seat and the two were away. There was
+scant room for a rise between the spot where the
+machine lay and the foot of the range, but Ned
+had little difficulty in getting into the sky and
+swinging along in the breeze.
+</p>
+<p>
+It was now after ten o’clock, and the moon
+was high in the heavens. To the east the dark
+passes of the mountains showed green and misty
+in the moonlight. To the west the burned
+spaces looked dark and forbidding, with smoke
+half hiding the ruin that had been wrought.
+Jimmie clung to the machine and insisted that
+Ned was chasing the Milky Way when he lifted
+the aeroplane up the level of the divide.
+</p>
+<p>
+Before crossing the divide, however, Ned
+flew to the Great Northern right of way and
+filled his tanks with gasoline, also filling the
+extra keg. The machine, which was an improved
+Wright, was then turned to the north-east.
+So perfect have aeroplanes now become
+that even inexperienced drivers may sometimes
+venture into the air with them with impunity,
+still it is well known that it is more the man than
+the machine that decides whether there shall be
+a tumble or a successful flight.
+</p>
+<p>
+The aeroplane is a wonderful invention, yet
+the point which really makes it so serviceable
+<span class='pagenum pncolor'><a id='page_128'></a>128</span>
+is a very simple one. For years inventors studied
+ways of making a heavier-than-air machine
+sail through the sky like a bird. Then the gasoline
+engine came, and all the rest seemed easy.
+</p>
+<p>
+But no one could keep control of the aeroplane.
+It moved about according to its own
+whims, and tipped drivers out at its own sweet
+will. Then the Wrights thought of lifting and
+lowering the planes to represent the wings and
+feathers of a bird. The secret had been found
+and required only experience and practice. Here
+was a machine light enough to fly, yet strong
+enough to carry with safety its powerful engine
+and two or more passengers, if there is room
+provided for them.
+</p>
+<p>
+It is so stout that a man may walk over it
+while it lies on the ground, and yet so delicate
+in control when in the air that a slight pull on
+a lever will dip one wing, lift the other, and at
+the same time turn a vertical tail-rudder about
+to give the necessary balancing pull with almost
+the instinctive adaptability of a bird’s wings and
+feathers.
+</p>
+<p>
+And this wonderful machine, while speeding
+through the air with the velocity of an express
+train, can be halted almost instantly and whirled
+about on its tail. It will be seen that it is the
+<span class='pagenum pncolor'><a id='page_129'></a>129</span>
+man at the levers who makes or breaks a journey
+in the air. One man may do almost anything
+with a machine, while another may send
+himself to eternity with the same one. It was
+Ned’s good fortune that he was naturally ingenious
+and quick to make his hands follow the
+impulses of his brain.
+</p>
+<p>
+When a person is thundering through the
+air, a thousand feet above the earth, he must
+remain perfectly calm, even with the engine
+thundering behind his ears, tears running in
+streams down his face, and the wind fluttering
+his clothes into rags and ravelings, as he wishes
+he was back on land.
+</p>
+<p>
+Besides, there are no level plains in the air,
+as there are on earth. Every bird-man knows
+that he is liable to come up against a fierce current
+or tumble into a hole in the atmosphere
+at any moment. While traveling in water one
+can see what is ahead and on both sides, but
+this is not so in the air. The currents, swirls,
+eddies, holes, do not show at all.
+</p>
+<p>
+When Ned left the cachÃĐ where the gasoline
+and provisions had been hidden away, he put on
+half speed, swinging steadily skyward on a broad
+spiral. His purpose was to pass over the summit
+and have a look at the forests on the east side.
+<span class='pagenum pncolor'><a id='page_130'></a>130</span>
+</p>
+<p>
+The passenger’s seat in the Wright machine
+is in the middle. The engine is at his right and
+the driver at his left, so that the balance is the
+same whether an extra person is carried or not.
+Jimmie was glad of this, for it placed him close
+to Ned. In that half light, with the earth far
+below, with the pounding of the engine and the
+whistling of the wind, the boy felt the need of
+close human companionship.
+</p>
+<p>
+He sat in a wooden seat with his back against
+the rest, holding to one of the uprights with both
+hands, and resting his tingling feet on a cross-bar.
+A guy-wire passed across in front, close
+to his chest, so he was now fastened in.
+</p>
+<p>
+He wanted to talk with Ned, to hear the
+sound of his voice, but the clamor of the engine
+prevented that, so he just sat still and looked
+down on the flying forest below. It seemed to
+him, at least, that the forest was moving, while
+he was standing still in the starlight.
+</p>
+<p>
+Up the aeroplane went, and still higher up.
+Jimmie saw the great divide below, and saw
+little red specks in the forests of the eastern slope
+which denoted forest fires not yet grown to
+maturity. After passing the summit Ned saw
+the campfire of the men Ernest had spoken of.
+He passed them, swung around a circle lower
+<span class='pagenum pncolor'><a id='page_131'></a>131</span>
+down, selected a spot where he thought he could
+land with safety, and dropped down.
+</p>
+<p>
+Jimmie declared afterwards that he felt as
+if he had been thrown out of the window of a
+twenty-story building—and the highest window
+at that. When the aeroplane came into the
+shadows of the high trees where the landing was
+being made he knew that a wind was blowing at
+the surface and feared that the machine would
+be carried along on the ground and dumped over
+into a caÃąon.
+</p>
+<p>
+The machine sank gracefully into a glade
+rather high up on the slope, and the boys alighted
+to stretch their legs. Ned’s first move was to
+see if there was plenty of room for him to get
+out. What he found was an incline to the east,
+an incline ending at a great caÃąon, into which
+he would have been hurled had the aeroplane
+run fifty feet farther on the ground.
+</p>
+<p>
+“I think I can make it,” he said, “but it is
+risky. It wouldn’t be nice to take a header a
+thousand feet down.”
+</p>
+<p>
+After the inspection of the locality Ned extinguished
+all the lights and sat down to map
+out his plans for the remainder of the night.
+There were the usual noises of the forest, as
+found at night, but no human sounds intruded.
+<span class='pagenum pncolor'><a id='page_132'></a>132</span>
+</p>
+<p>
+Ned knew that the clamor of the engine must
+have been heard by the men in the camp he had
+flown over, and he had no doubt that the outlaws
+would make a quick excursion to his landing
+place, if they could determine where it was. So
+he put out the lights and listened for some indication
+of the approach of the others.
+</p>
+<p>
+“They won’t find us in a thousand years,”
+Jimmie volunteered, as the two sat close together
+under a great tree.
+</p>
+<p>
+“I hope not,” Ned replied, “for then we
+shall have a better chance to find them.”
+</p>
+<p>
+“What do you want to find ’em for?” questioned
+the boy. “You can’t pinch ’em, ’cause
+you haven’t got the proof, an’ you couldn’t if
+you had the proof, ’cause there ain’t enough of
+us. They’d eat us up like spinach.”
+</p>
+<p>
+“You are right as far as you have gone,”
+Ned replied, “but you have not gone far enough.
+What I want now is to find out what they are
+doing here. And, also, I want to find out about
+that fellow from San Francisco. If the description
+is any good, he was in the city when I left
+it, and I don’t see how he ever got here so soon.
+I came part way on an aeroplane, but it seems
+that he traveled farther and beat me out.”
+<span class='pagenum pncolor'><a id='page_133'></a>133</span>
+</p>
+<p>
+“What’s he got to do with it?” asked Jimmie.
+“What did you find out in the city? You won’t
+have no luck if you don’t tell me all about it.”
+</p>
+<p>
+So, while they waited, Ned told him “all
+about it,” while the boy sat in the dusk with
+his eyes and mouth both opened wide at the
+mystery of the thing.
+</p>
+<p>
+“I don’t believe Albert Lemon ever got out
+here so soon,” the lad said, when the story was
+told. “He couldn’t.”
+</p>
+<p>
+“Then who is the man from San Francisco?”
+asked Ned.
+</p>
+<p>
+“It can’t be the dead man?” questioned
+Jimmie.
+</p>
+<p>
+“You saw him buried,” Ned answered.
+</p>
+<p>
+“Then I give it up!” Jimmie said.
+</p>
+<p>
+The two sat there in silence a long time, then
+Jimmie gave Ned’s arm a pull and pointed to a
+flickering light in the forest just above the glade
+where the aeroplane rested.
+</p>
+<p>
+“They think you’ve landed somewhere here,”
+the boy said, “an’ have set fire to the woods.”
+</p>
+<p>
+“I think you have guessed it,” Ned said.
+“However, the blaze won’t run very fast up
+there, for the undergrowth is scanty, so we’ve
+got plenty of time to get out of the way.”
+<span class='pagenum pncolor'><a id='page_134'></a>134</span>
+</p>
+<p>
+Jimmie scrambled up the slope, clinging to
+rocks and roots with both fingers and feet, and
+ran toward the blaze. Ned watched the little
+fellow dashing along with no little anxiety, for
+the outlaws might be there in the thickets,
+watching for some attempt to be made to lift
+the aeroplane.
+</p>
+<p>
+He saw Jimmie recklessly climb to the top of
+a great rock which jutted out from the side of
+the mountain and saw his figure outlined against
+the growing blaze on the slope above. Then
+the fire died down, as if for want of material,
+and the top of the rock could no longer be seen.
+</p>
+<p>
+Ned listened, but Jimmie did not return.
+The effort to create a general conflagration on
+the mountain side had evidently failed, for there
+was little to burn save the green boles of trees,
+that section having been swept by fire a year
+before.
+</p>
+<p>
+Not daring to leave the aeroplane for even an
+instant, Ned awaited the return of the boy with
+premonitions of trouble in his mind. Presently
+he heard a shot, then a cry, and after that a
+brutal laugh. The outlaws were nearer than he
+thought.
+</p>
+<p>
+There was only one thing for Ned to do,
+and that was to get the aeroplane into the sky
+<span class='pagenum pncolor'><a id='page_135'></a>135</span>
+immediately, and so once more place it beyond
+the reach of the outlaws. There was nothing he
+could do to aid Jimmie, he reflected, sadly, by
+remaining there.
+</p>
+<p>
+It was no task at all to start the rollers down
+the incline, but the caÃąon threatened if he did
+not get it off the ground in quick time. He
+knocked the stones out from under the wheels
+and sprang into his seat. The machine, gaining
+momentum, moved on sedately. It had
+acquired a fair rate of speed when he came within
+a few feet of the caÃąon.
+</p>
+<p>
+Then, after letting it get all the headway
+possible in that confined space without coming
+too close to the caÃąon, Ned pulled the lever
+which tilted the front rudder planes. Trifling
+as the deflection was the man-made bird felt
+its influence and rose from the slope as if endowed
+with life.
+</p>
+<p>
+It reached the edge of the descent some distance
+in the air, and the boy was congratulating
+himself on the success of his unaided rise when
+the big machine began to sag as if dropping to
+the ground, five hundred feet below.
+</p>
+<p>
+The west wall of the caÃąon ran straight down,
+and it seemed to Ned that he was following it,
+like an iron spike thrown off the ledge. He
+<span class='pagenum pncolor'><a id='page_136'></a>136</span>
+knew very well what had occurred. He had
+fallen into one of the down-tipping currents so
+frequent in mountain districts.
+</p>
+<p>
+The air, he knew, was sliding down the precipice
+just as water tumbles over a dam. If it
+turned, as it might, when it struck the lower
+strata of air, he might secure control of his machine
+and manage to lift it out of the caÃąon. If
+it did not, he would doubtless fall to the rocky
+floor of the caÃąon, and lie there until some
+chance hunter or forester came upon a heap of
+bleaching bones and the wreck of an aeroplane.
+</p>
+<p>
+But even at that swift pace downward, and
+at that exciting moment, Ned found himself
+puzzling over the strange sight he saw in a break
+in the wall of the caÃąon. It was a large opening
+he looked into, and strange figures were gathered
+about a cooking fire.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_137'></a>137</span><a name='chXI' id='chXI'></a>CHAPTER XI.—THE LUCK OF A BOWERY BOY.</h2>
+<p>
+Jimmie opened his eyes and looked about.
+It was a gloomy niche in a perpendicular wall
+that he looked out of. Rock to right and left
+and rear. In front a velvet summer sky, with
+stars winking over a vast stretch of broken
+country. There was a ledge a foot in width
+outside the entrance to the niche, but the boy
+could not see how long it was, or where it led to.
+</p>
+<p>
+His head ached and there was a drawing
+sensation to the skin of his forehead and right
+cheek, as if some sticky substance had congealed
+there. When he reached a hand up to see what
+the trouble was he found that his head was tied
+up in a cloth. There was no one in sight to ask
+questions of, so he arose to a sitting position
+and leaned forward.
+</p>
+<p>
+The action brought on a whirl of dizziness,
+and he dropped back against the wall for support.
+He knew then that he had received a hard
+blow on the head, and that he had lost considerable
+<span class='pagenum pncolor'><a id='page_138'></a>138</span>
+blood. Once before in his life he had felt
+that dizzy weakness, and that was after an artery
+had been cut in his leg and he had nearly
+bled to death before reaching a hospital.
+</p>
+<p>
+When he lay back trying to get something
+like a balance in his brain, he saw that it was
+near midnight. He knew that by the stars, for
+he had watched them many a hot night, lying
+on his back on a dray backed up some alley
+down near the East river, in New York.
+</p>
+<p>
+There were certain stars which always occupied
+just such a position at midnight in New
+York. He did not know their names, but he
+knew that at midnight in Montana they would
+not be so far advanced across the sky. Therefore
+he looked for the stars as they appeared at
+nine o’clock on the Atlantic. When he found
+them he knew from their location that it had
+been something over an hour since he had left
+Ned and the aeroplane.
+</p>
+<p>
+The three hours difference in time between
+New York and Montana—three hours in round
+numbers—would make the midnight stars three
+hours late, of course. Anyway, the boy was
+pretty certain of the time.
+</p>
+<p>
+Then his mind went back to Ned and the
+aeroplane, and the caÃąon in front of the landing
+<span class='pagenum pncolor'><a id='page_139'></a>139</span>
+place. He recalled the stop, and remembered
+leaving Ned to see what was doing in the way
+of forest fires. He remembered, too, getting up
+on a high rock to look over at the creeping flames.
+</p>
+<p>
+But strange to say he did not remember getting
+down again. The next thing on the record
+of his mind was that niche in the wall and the
+stars shining down out of a summer sky, the
+same stars he had looked at in old New York.
+Of course he had been struck the blow he had
+received while mounting the rock, otherwise he
+would know something of the attack.
+</p>
+<p>
+His mind did not have to travel along the
+records of the past very far to convince him that
+he had made a mistake in leaving Ned. Of
+course he had been “geezled” by the outlaws,
+as he expressed it, and of course the boys would
+delay the business they were on in order to look
+him up—which, he reluctantly admitted to himself,
+would be a waste of time, as any boy capable
+of doing such foolish stunts certainly was
+not worth the trouble of looking up.
+</p>
+<p>
+Presently the pain in his head became less
+violent and the dizziness in a measure passed
+away. Then he pushed out to the edge of the
+ledge and sat with his feet hanging over. It
+was a straight drop down. Below he could see
+<span class='pagenum pncolor'><a id='page_140'></a>140</span>
+a stream of water running along the bottom of
+the caÃąon.
+</p>
+<p>
+Out, perhaps two hundred yards from his resting
+place, he saw a slope half covered with trees.
+He looked down into the gulf in the hope of seeing
+the aeroplane, but it was not in sight. Ned
+must have taken it away. Or he might have
+been overpowered and the machine broken up.
+</p>
+<p>
+Of course the outlaws would break up the
+machine if they secured possession of it. They
+would not dare use it in that region, and it was
+about as handy a thing to ship away secretly
+as a white elephant.
+</p>
+<p>
+There were no lights in sight anywhere, save
+a slight glow of coals away down at the bottom
+of the caÃąon. That might be the remains of
+the aeroplane, or it might be a bit of forest fire
+which had not burned itself out. Very much
+disgusted with himself, the boy leaned farther
+out wondering if there wasn’t a ledge which
+wound its way to the bottom of the caÃąon, or
+to the summit above.
+</p>
+<p>
+So intently was he studying on this proposition
+that he did not hear footsteps approaching,
+nor did he realize that there was any human
+being near him until he felt a hand laid lightly
+on his shoulder.
+<span class='pagenum pncolor'><a id='page_141'></a>141</span>
+</p>
+<p>
+“Be careful, young man,” the voice said,
+“or you’ll get another tumble. How do you
+feel by this time?”
+</p>
+<p>
+“Fine!” cried the boy, turning a pair of
+astonished eyes toward the south, where a bulky
+personage stood blocking the ledge to the extent
+of obscuration.
+</p>
+<p>
+“Well, don’t take any more chances, then,”
+said the bulky person, and Jimmie was forced,
+not ungently, back into the niche.
+</p>
+<p>
+The man entered after the boy and threw
+himself down on the stone floor of the cut in the
+wall of the caÃąon. He was short and stout,
+with a double chin and a pointed forehead which
+gave his face the appearance of being engraved
+on a lemon. He was quite bald, and his hair,
+that which remained, was turning gray. His
+eyes were steel blue, and his mouth one long,
+thin-lipped slit between fat cheeks.
+</p>
+<p>
+Jimmie did not like his looks at all, and he
+resented the patronizing voice and manner. So
+he leaned sullenly against the wall and waited for
+the other to open the conversation. He had not
+long to wait, for the man was busy in a moment.
+</p>
+<p>
+“How did you get that fall?” he asked.
+</p>
+<p>
+So, Jimmie thought, they were going to claim
+that he had a fall, and that they had found him,
+<span class='pagenum pncolor'><a id='page_142'></a>142</span>
+and cared for him gently, and were now ready
+to do anything in the world for his comfort.
+The boy decided that the correct course for him
+to pursue was to follow the lead of the other.
+</p>
+<p>
+“Guess I slipped off a rock,” he said, knowing
+very well that he had been knocked off his
+feet so suddenly that he had instantly lost consciousness.
+</p>
+<p>
+“What were you doing there?” was the next
+question.
+</p>
+<p>
+“Why, I had been out in the aeroplane, and
+I got out to see if the forest fire I saw was going
+to be anything serious, and then I tumbled.”
+</p>
+<p>
+“Where is the boy who was with you in the
+aeroplane?” asked the other.
+</p>
+<p>
+Jimmie replied that he had no idea, which
+was, of course, the answer expected of him. His
+questioner remained silent a moment, looking
+out over the rugged land to the east. When he
+spoke again it was to ask:
+</p>
+<p>
+“What are you doing in the Rocky Mountains?”
+</p>
+<p>
+Jimmie thought that was a cheeky question,
+and a useless one, for he had no doubt that the
+fellow knew nearly as much about his business
+as he did about his own.
+<span class='pagenum pncolor'><a id='page_143'></a>143</span>
+</p>
+<p>
+“We’re on a vacation,” he replied. “Five
+of us have a camp over on the other side of the
+divide. We’re just playing prospectors.”
+</p>
+<p>
+“Very nice vacation for you all,” the other
+said, “but you ought to be more careful with
+your fires. You started a large conflagration
+yesterday.”
+</p>
+<p>
+So the Boy Scouts were to be accused of that!
+Jimmie wished at that moment that the other
+boys were there. He wanted to tell this fat
+hypocrite what he thought of him and stand a
+fair show in the fracas which might follow.
+</p>
+<p>
+“I don’t think we set any fires,” he said.
+“The fires started a long way from our camp.”
+</p>
+<p>
+“I know what I’m talking about,” the other
+said.
+</p>
+<p>
+Jimmie did not reply. He was wondering
+what would be the next move of the fat party,
+and whether Ned or the boys left in camp would
+be out to look him up before the morning.
+</p>
+<p>
+“I am in charge of this district,” the other
+went on. “I’m Captain Slocum of the forestry
+force.”
+</p>
+<p>
+Jimmie did not believe it, but did not say so.
+He only stared at the other in a manner which
+nettled his dignity.
+<span class='pagenum pncolor'><a id='page_144'></a>144</span>
+</p>
+<p>
+“I have been watching you boys ever since
+you have been here,” Captain Slocum went on.
+“I didn’t know what you were up to, and so I
+watched.”
+</p>
+<p>
+“Yes, sir,” said Jimmie, quite humbly,
+though angry enough to fight the man single-handed.
+</p>
+<p>
+“It seems that you have left forest fires
+wherever you have camped,” Slocum went on,
+with an all-knowing air. “To-night I sent a
+party of foresters over to the camp to arrest you
+all.”
+</p>
+<p>
+“Yes, sir,” replied Jimmie again, shutting
+his lips hard in order to prevent saying a great
+deal more.
+</p>
+<p>
+“Do you think they will find this Ned Nestor
+there?” Slocum asked, then.
+</p>
+<p>
+“I don’t know whether he could get his machine
+back to the camp,” Jimmie replied.
+</p>
+<p>
+“Well, wouldn’t he go without it?”
+</p>
+<p>
+“No, sir; I don’t think he would, unless it
+was certain that he could not take it with him.”
+</p>
+<p>
+“We’ll find him, anyway,” Slocum continued.
+</p>
+<p>
+“Where are you goin’ to take us for trial?”
+Jimmie asked.
+<span class='pagenum pncolor'><a id='page_145'></a>145</span>
+</p>
+<p>
+“We’ll have to consider that part of the matter
+later on,” was the reply. “The first thing
+for us to do is to lock you up good and tight and
+stop the setting of forest fires.”
+</p>
+<p>
+“Yes, sir,” replied Jimmie, still humbly, but
+still thinking what he would do to this fat falsifier
+if he ever got a chance.
+</p>
+<p>
+“I’m glad you confess,” Slocum said.
+</p>
+<p>
+“I didn’t,” said Jimmie.
+</p>
+<p>
+“Why, yes, you did,” insisted the other.
+“You admitted setting the fires.”
+</p>
+<p>
+Jimmie made no reply. Far down in the
+caÃąon he saw a glint of flame. It was not a forest
+fire. It was not even the red light of a campfire
+or a lantern. The light was white, and the
+boy knew it for what it was—an electric searchlight,
+such as Ned always carried on his aeroplane
+trips.
+</p>
+<p>
+Slocum did not seem to see the light. His
+eyes were fixed on the face of the boy he was
+talking with, although the features did not show
+very distinctly in the dim light of the night.
+</p>
+<p>
+“Well, to tell you the truth, we’ve already
+captured this Ned Nestor,” Slocum added, maliciously,
+Jimmie thought, “and no doubt my
+men have also captured those at the camp.
+Nestor broke a leg in trying to get away, but
+<span class='pagenum pncolor'><a id='page_146'></a>146</span>
+when he was fairly cornered he confessed everything.”
+</p>
+<p>
+“Yes, sir,” answered Jimmie.
+</p>
+<p>
+There was nothing else the boy could say
+without putting himself in the way of a beating.
+If he had expressed his opinion of this story no
+doubt he would have been given physical punishment
+for his frankness.
+</p>
+<p>
+“And so,” Slocum smiled, “you may as well
+continue the confession you began.”
+</p>
+<p>
+Jimmie recognized this as clumsy work in
+the third degree, but he did not say so. He
+was watching the light below. Now it disappeared
+behind a great rock or tree. Now it
+came out in the opening again and moved about
+in a circle.
+</p>
+<p>
+“Ned is examining his ’plane, preparatory to
+going back to camp,” the boy thought. “Wonder
+if he’s been all this time lookin’ for me?”
+</p>
+<p>
+The boy paid little attention to what Slocum
+said after this. Most of the time he was
+looking into the sky, or anywhere rather than
+where his thoughts were fixed. He had no intention
+of directing the gaze of the alleged forester
+to what was going on in the caÃąon.
+</p>
+<p>
+Directly he saw the flashlight flutter over
+the white planes then become stationary. Ned,
+<span class='pagenum pncolor'><a id='page_147'></a>147</span>
+he knew, was getting ready to make a flight. He
+could imagine what the boy’s feelings were, for
+he knew Ned’s affection for him. Indeed, it
+was with a heavy heart that the patrol leader
+left the place without Jimmie.
+</p>
+<p>
+“And there is also a suspicion that you
+boys are interested in getting opium over the
+border without settling with Uncle Sam,” Jimmie
+heard Slocum saying, as he watched the
+aeroplane move forward, lift for a moment, and
+then drop down out of sight. He knew of the
+precipice just ahead of the machine, and trembled
+for fear that Ned had not been able to lift the
+aeroplane, but had tumbled into the caÃąon with
+it.
+</p>
+<p>
+“Anyway,” Slocum continued, “we shall
+place you under arrest for setting fire to the
+woods and also for smuggling.”
+</p>
+<p>
+Just at that moment Jimmie was not at all
+interested in what Slocum was saying to him.
+He took no interest whatever in any threat
+made by the fellow. He was watching the
+caÃąon for some sign of the reappearance of the
+aeroplane.
+</p>
+<p>
+After what seemed an eternity to the lad he
+saw the light again, this time higher up than before.
+<span class='pagenum pncolor'><a id='page_148'></a>148</span>
+It was lifting slowly, turning round and
+round in a spiral, and Jimmie knew that there
+was no room to mount into the sky in a straight
+line. Ned’s control of the machine was wonderful,
+and it lifted gradually until it was above
+the line of the hills on the other side and shot
+away to the west.
+</p>
+<p>
+Then Slocum saw it. Jimmie blamed himself
+for calling his attention to it by lifting his
+head to follow the flight across the sky.
+</p>
+<p>
+“There is another aeroplane,” Slocum said.
+</p>
+<p>
+Jimmie could not restrain a laugh, which
+intruded oddly enough on the tense silence of
+the moment.
+</p>
+<p>
+“You don’t think it is Nestor, do you?”
+Slocum asked.
+</p>
+<p>
+“Yes, sir,” replied Jimmie, still humbly.
+</p>
+<p>
+“But he must have taken a drop down the
+caÃąon,” urged Slocum.
+</p>
+<p>
+“Yes, sir,” replied Jimmie, “but you said
+you had captured him!”
+</p>
+<p>
+Slocum eyed the boy with rage in his eyes.
+He knew very well that while he had been telling
+of Ned’s capture and confession, Jimmie
+had been watching his chum get his aeroplane
+out of the caÃąon.
+<span class='pagenum pncolor'><a id='page_149'></a>149</span>
+</p>
+<p>
+“You haven’t even thanked me for getting
+you out of the mess I found you in, and doctoring
+up your wound,” he said, presently, resolved
+to keep on good terms with the boy for a short
+time longer, if it was possible to do so.
+</p>
+<p>
+“Thank you, sir!” Jimmie said, very modestly.
+“I think I must have received a good
+bump on the head.”
+</p>
+<p>
+“Indeed you did,” smiled the other.
+</p>
+<p>
+After a little further talk Slocum led the boy
+away to a cavern in the wall of the caÃąon which
+seemed to the weary lad to have no end. He
+saw several people lounging about as he passed
+through a large chamber, but paid little attention
+to them.
+</p>
+<p>
+At last Slocum halted in a little alcove opening
+from a second chamber, in which were assembled
+at least a score of Chinamen.
+</p>
+<p>
+“These people won’t harm you,” he said to
+the boy, swinging his arm about to include the
+group. “Uncle Sam is trying them out in the
+forest service, I don’t think much of the idea
+myself, but I’m not the boss.”
+</p>
+<p>
+Then Slocum went away and Jimmie lay
+down and watched the Chinamen. Listening,
+he heard one of them speaking in English, then
+in Chinese. He knew that he had heard that
+<span class='pagenum pncolor'><a id='page_150'></a>150</span>
+peculiar voice and dialect before and devoted
+his whole attention to the fellow.
+</p>
+<p>
+“Well,” he muttered, in a moment, with a
+grin, “I’m havin’ the luck of a Bowery boy in
+this deal, an’ that is the greatest luck in the
+world.”
+</p>
+<p>
+Then he fell to wondering what Chang Chee,
+the keeper of one of the worst Chinese restaurants
+on Doyers street was doing there, in the
+heart of the Rocky Mountains, mixed up with
+alleged foresters.
+</p>
+<p>
+“Just wait until I see Ned!” the boy mused.
+“I’ll put him next to somethin’. He’ll be glad
+he brought me with him!”
+</p>
+<p>
+Then the boy’s thoughts went back to the
+camp in the Valley of the Wild Beasts, as he
+called it. Slocum might have told the truth
+about the attack on the boys, and they might
+be in trouble at that moment. He wondered,
+too, if, in case they were taken prisoners, they
+would be brought to the cavern.
+</p>
+<p>
+“Anyhow,” the lad mused, “they never
+intend to let me get out of this. If they did,
+they wouldn’t have permitted me a sight of the
+Chinks. Unless I sneak away, there’ll be an
+accident some day, an’ then there’ll be no more
+Jimmie McGraw!”
+<span class='pagenum pncolor'><a id='page_151'></a>151</span>
+</p>
+<p>
+The boy was tired and weak, so that even
+such serious thoughts as these could not keep
+him awake. Wondering what conditions Ned
+had found at the camp, after soaring out of the
+caÃąon, he dropped his head against the stone
+wall of the alcove and was soon in a deep sleep.
+The fumes of opium with which the cavern was
+filled might in a measure have contributed to
+this, but, anyway, nature was exhausted, and
+the boy’s slumber was heavy and dreamless.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_152'></a>152</span><a name='chXII' id='chXII'></a>CHAPTER XII.—A MEMBER OF THE OWL PATROL.</h2>
+<p>
+When Jimmie awoke the fire which had
+burned in the cavern had gone out, and those
+who remained in the chamber seemed to be fast
+asleep. He tumbled out of his alcove, still feeling
+weak and dizzy, and moved toward a hanging
+rug which closed the entrance to the place.
+</p>
+<p>
+He drew one side of the rug back and saw
+the white light of day. The sun seemed to be
+high up in the sky, for the ledge at the front of
+the cavern showed a streak of gold. Two Chinamen
+sat at the entrance to the outer cave, and
+when he advanced toward them they waved
+him back. Instead of retreating he stood regarding
+them with a puzzled look on his face.
+</p>
+<p>
+One was Chang Chee, the keeper of the disreputable
+Chinese dive on Doyers street, whom
+Jimmie had noticed the night before, and the
+other was a much younger man—a boy, in fact.
+When Chang ordered Jimmie back the youngster
+turned toward him a face showing both curiosity
+and interest.
+<span class='pagenum pncolor'><a id='page_153'></a>153</span>
+</p>
+<p>
+“What’s doin’ here?” Jimmie demanded, in
+a moment.
+</p>
+<p>
+He thought best not to show that he recognized
+Chang, for he knew that the identification
+of the Chinaman would only add to his peril, if
+that were possible. It was certain that Chang
+would never permit the information that he had
+been seen there to get out to the government
+officers.
+</p>
+<p>
+Jimmie’s idea at that time was that he had
+blundered on a gang of opium smugglers, although
+he could not understand why so many
+Chinamen were, apparently, engaged in the illegal
+traffic.
+</p>
+<p>
+Chang finally turned his face away, with a
+frown, and Jimmie advanced a step toward the
+boy, who threw himself carelessly down on his
+back and extended his right arm straight up
+from the shoulder. Jimmie’s eyes opened wider,
+and his breath almost stopped, when he saw the
+thumb and little finger thrown diagonally across
+the palm of the hand, the tip of the thumb covering
+the nail of the little finger, the three remaining
+fingers pointing upward.
+</p>
+<p>
+In the excitement of the moment, in the
+amazement caused by his recognition of the
+Boy Scout challenge, Jimmie lost all caution.
+<span class='pagenum pncolor'><a id='page_154'></a>154</span>
+</p>
+<p>
+“Say!” he began, but Chang turned a repulsive
+face and ordered him into the rear
+chamber.
+</p>
+<p>
+The boy, thankful for the interruption,
+moved back a few paces, believing that the
+Chinese boy who had given him the sign would
+communicate with him as soon as opportunity
+offered.
+</p>
+<p>
+This was the greatest puzzle the lad had ever
+been called upon to solve. Some of the questions
+he asked himself were:
+</p>
+<p>
+“How did that Chinese boy become a Boy
+Scout?”
+</p>
+<p>
+“Is there a Chinese patrol?”
+</p>
+<p>
+“Was he permitted to become a member of
+an American patrol?”
+</p>
+<p>
+“Why is he mixed up with that disreputable
+old Chink?”
+</p>
+<p>
+“Will he help me out of this hole, or will he
+ignore me?”
+</p>
+<p>
+Of course there was not one of the questions
+the boy could answer, so he went back to his
+alcove and sat down, half believing that he had
+imagined the challenge.
+</p>
+<p>
+As the day wore on the men who had been
+asleep in the inner chamber arose, staggeringly,
+as if still under the stupefying influence of opium,
+<span class='pagenum pncolor'><a id='page_155'></a>155</span>
+and made their trembling way outside.
+When they had all disappeared Chang pushed
+the rug aside so as to bring more light and air
+into the place and came and stood looking down
+on the boy.
+</p>
+<p>
+Jimmie did not look up. He saw the shrunken
+figure up as far as the knees only. He was
+resolved not to open any conversation with the
+Chink. If he wanted to talk, Jimmie thought,
+let him choose his own subject and introduce
+it in his own way.
+</p>
+<p>
+The yellow face of the Chinaman seemed to
+take on a more mask-like expression—or want
+of expression, rather—as the silence continued.
+When he spoke it was with a snarl which boded
+no good to the boy.
+</p>
+<p>
+“Hungly?” he demanded.
+</p>
+<p>
+“Hungry?” repeated Jimmie. “You know
+it! If you’ve got any rat sandwiches or puppy
+potpies, just introduce me!”
+</p>
+<p>
+“Flesh!” growled Chang.
+</p>
+<p>
+“Flesh?” repeated Jimmie. “Oh, yes, you
+mean fresh? Well, you’d be just as fresh as I
+am if you were as hungry.”
+</p>
+<p>
+“Cheek!” cried Chang. “Kid allels have
+cheek—an’ tummy!”
+<span class='pagenum pncolor'><a id='page_156'></a>156</span>
+</p>
+<p>
+“Sure,” said Jimmie. “Go on an’ get me
+a porterhouse steak with French potatoes. I
+could eat a car of raw onions.”
+</p>
+<p>
+Chang turned away and walked out to the
+ledge, where the Chinese boy stood, looking out
+into the sunshine. It was a glorious morning,
+with the air clear and just a little sharp, owing
+to the altitude. Here and there little swirls of
+smoke showed that fires were burning in the
+forest, though none seemed to be close to the
+range.
+</p>
+<p>
+Reaching the boy’s side Chang addressed a
+few words to him in Chinese and left the cave,
+turning back, after a few paces, to observe the
+boy, now standing with a long, keen-bladed
+clasp-knife in his hand. As Chang looked the
+boy ran his finger over the edge of the blade, as
+if to make sure that it was suitable for some purpose
+he had in view.
+</p>
+<p>
+With an exclamation of rage Chang charged
+back at him and snatched the knife from his
+hand.
+</p>
+<p>
+“You fool!” he cried.
+</p>
+<p>
+“You let me alone!” shouted the other. “I
+tell you, I’m going to kill him!”
+</p>
+<p>
+Jimmie heard the words and rose unsteadily
+to his feet. He recognized the voice as that of
+<span class='pagenum pncolor'><a id='page_157'></a>157</span>
+the boy who had given him the Boy Scout challenge.
+At least it was not that of Chang, and
+there were only two figures outlined against the
+sky when he looked out beyond the rug, still
+pushed aside.
+</p>
+<p>
+“Fool! Fool! Fool!”
+</p>
+<p>
+Chang gritted out the words as he took the
+Chinese boy by the back of the neck and hustled
+him into the cave. Then he spoke for a
+minute in Chinese and turned away again.
+Jimmie stepped back into his alcove and felt
+around for a stone, or anything in the shape of a
+weapon, as the boy advanced toward him.
+</p>
+<p>
+“What does the badge say?”
+</p>
+<p>
+Jimmie opened his eyes wider than ever, if
+possible, and stood facing the boy, half hiding
+the stone he had found.
+</p>
+<p>
+“Be prepared,” he replied.
+</p>
+<p>
+“Then drop that rock!”
+</p>
+<p>
+Jimmie dropped it and stepped forward.
+</p>
+<p>
+“Liu, Owl patrol, San Francisco,” the Chinese
+boy said.
+</p>
+<p>
+“McGraw, Wolf patrol, New York,” replied
+Jimmie.
+</p>
+<p>
+“You don’t look very comfortable in here,”
+Liu said.
+<span class='pagenum pncolor'><a id='page_158'></a>158</span>
+</p>
+<p>
+“Nixy,” replied Jimmie, wondering if the
+boy really was preparing to carry out the threat
+he had made to Chang.
+</p>
+<p>
+“You heard what I just said to Chang?”
+Liu asked.
+</p>
+<p>
+Jimmie nodded his bandaged head.
+</p>
+<p>
+“Bluff!” said Liu. “He’s watching now to
+see that I don’t make an attempt on your life.
+Had to do it!”
+</p>
+<p>
+“I see,” Jimmie replied, wondering if it
+wasn’t pretty near time to wake up.
+</p>
+<p>
+“Why don’t he want me killed?” Jimmie
+asked in a moment.
+</p>
+<p>
+“He thinks you have information he needs,”
+was the answer. “Are you hungry?”
+</p>
+<p>
+“That’s what Chang asked,” Jimmie said,
+“but he didn’t bring me any grub.”
+</p>
+<p>
+“He told me to,” grinned Liu, “and I told
+him that I’d kill you if I got near enough to
+do so. He’ll hang around until he sees me
+bring you something to eat.”
+</p>
+<p>
+“You ain’t so very slow yourself,” grinned
+Jimmie. “Where did you learn to speak United
+States so well?”
+</p>
+<p>
+“Born in Frisco,” was the reply. “The
+Boy Scouts take me out on their hunting trips
+to do the cooking. That’s why I’m here now.
+<span class='pagenum pncolor'><a id='page_159'></a>159</span>
+I know the mountains, and Chang hired me to
+go along with him.”
+</p>
+<p>
+“An’ they took you into the patrol, did
+they?” asked Jimmie.
+</p>
+<p>
+“Sure they did,” was the reply. “Why
+not? I’m an American citizen, or will be in
+four years.”
+</p>
+<p>
+“Have they captured any of the others?”
+asked Jimmie.
+</p>
+<p>
+The Chinese boy shook his head.
+</p>
+<p>
+“Have they heard from the men they sent
+out to capture them?” was the next question.
+</p>
+<p>
+Another shake of the head, then Liu drew
+closer and whispered.
+</p>
+<p>
+“Do you see Chang poking his head around
+that rock in the opening? He’s watching to see
+that I don’t knife you!”
+</p>
+<p>
+Jimmie saw the parchment-like face of the
+old reprobate peering around the rock and
+wanted to heave a stone at it, but knew that
+this would not be good policy. Instead he
+threw it at Liu, and missed, of course.
+</p>
+<p>
+“You seem to be wide awake yourself,” Liu
+said.
+</p>
+<p>
+“Why don’t you go and get me some grub?”
+demanded Jimmie. “I’m near starved to death.”
+<span class='pagenum pncolor'><a id='page_160'></a>160</span>
+</p>
+<p>
+“All right!” said Liu, and turned away.
+</p>
+<p>
+Jimmie was now in a deeper puzzle than
+before. He had no means of knowing whether
+Liu was telling him the truth. He might be
+trying to get into his confidence in order to gain
+the information sought, whatever it was.
+</p>
+<p>
+However, in a short time Liu returned with
+a generous supply of food, fried fish, fresh biscuit—the
+boy wondered how Liu had managed
+to bake them there—coffee, and plenty of tinned
+goods.
+</p>
+<p>
+“What’s this bunch doin’ here?” the boy
+asked, as he made heavy inroads on the fresh
+fish, coffee and biscuits.
+</p>
+<p>
+“I don’t know,” was the hesitating reply.
+</p>
+<p>
+“I know,” Jimmie went on. “They’re
+smuggling opium an’ setting fire to the woods.
+They’ll all get pinched!”
+</p>
+<p>
+“I hope so,” was the reply.
+</p>
+<p>
+“It sounds odd to hear a Chinese boy talk
+straight United States,” Jimmie said, after a
+short silence.
+</p>
+<p>
+Liu made no reply for a moment. He was
+watching the ledge outside the entrance to the
+cave. The occasional rattle of pebbles told
+him that some one was standing there, probably
+just out of sight.
+<span class='pagenum pncolor'><a id='page_161'></a>161</span>
+</p>
+<p>
+“What is Chang doin’ here?” Jimmie asked,
+presently.
+</p>
+<p>
+“He’s in some scheme with the foresters,”
+was the reply.
+</p>
+<p>
+“They ain’t no foresters!” Jimmie said.
+“They’re timber thieves an’ smugglers, an’
+firebugs, an’ murderers!”
+</p>
+<p>
+Liu shuddered but remained silent. After
+listening a second he went to the entrance and
+looked out. There was no one in sight at first,
+then a roughly dressed fellow came around the
+angle of the cliff to the north and approached
+him. The fellow was rather short for a man of
+his width of shoulder, and his step was remarkably
+light and quick for one of his apparent
+weight.
+</p>
+<p>
+His face was sun and wind-tanned, with
+plenty of mountain soil on top of that. A cartridge-belt
+encircled the loose jacket he wore and
+a revolver handle protruded from the pistol
+pocket of his trousers.
+</p>
+<p>
+“What’s the word?” he asked, gruffly, as
+he came up to Liu.
+</p>
+<p>
+“Go on in,” replied Liu.
+</p>
+<p>
+Jimmie saw evidences of treachery in the
+hostile attitude of the newcomer and retreated
+farther into the cavern.
+<span class='pagenum pncolor'><a id='page_162'></a>162</span>
+</p>
+<p>
+Then he saw Liu doubling up with laughter
+and stopped. It didn’t look very amusing to
+him, especially as the stranger was advancing
+toward him with swift strides. Then something
+remotely familiar in the set of the shoulders,
+the carriage of the head, attracted his
+closer attention to the figure and he moved forward
+a step.
+</p>
+<p>
+“You’re a nice little boy to get into a trap
+like this!”
+</p>
+<p>
+There was no mistaking that voice. Just
+how Ned Nestor had secured that disguise and
+found his way to that spot Jimmie did not stop
+to think. He knew that it was his chum, and
+that was enough. While the two boys clasped
+hands Liu stood regarding them smilingly, at
+the same time watching the entrance.
+</p>
+<p>
+“How did you ever find this hole?” Jimmie
+asked, his wonder at the thing which had happened
+mastering all else.
+</p>
+<p>
+“I saw this cave when my machine dropped
+into a hole in the air in the caÃąon,” was the
+reply. “The shelf where we landed is just
+above this cavern. There was a fire in the outer
+room, and numerous Chinamen were moving
+about.”
+<span class='pagenum pncolor'><a id='page_163'></a>163</span>
+</p>
+<p>
+“They’re opium smugglers,” Jimmie said.
+</p>
+<p>
+“Man smugglers!” laughed Ned.
+</p>
+<p>
+“Do you mean that they bring Chinks over
+the border here, an’ so run them down into
+civilization whenever they get a chance?” demanded
+Jimmie.
+</p>
+<p>
+“That is just it,” Ned answered. “We
+seem to have come upon a lot of the articles
+to be smuggled,” he added.
+</p>
+<p>
+“How did you come across Liu?” Jimmie
+asked.
+</p>
+<p>
+“Oh, I met him while I was prowling about
+not far from the cave, at daylight,” was the
+reply. “He helped me get this disguise.”
+</p>
+<p>
+Liu was still watching at the mouth of the
+cavern, so the boys talked freely, with little fear
+of being disturbed. Ned told of his return to
+the camp, and of the all-night hunt for the missing
+boy. It took Ned and Frank a long time
+to find the opening the former had seen in his
+swift drop down the caÃąon, but about daylight
+it was located.
+</p>
+<p>
+They had, however, found many Chinamen
+loitering about, and Frank had gone back to
+camp to reassure the others, while Ned remained
+on the eastern side on the chance of getting into
+<span class='pagenum pncolor'><a id='page_164'></a>164</span>
+communication with Jimmie. While loitering
+about Liu had come up the slope.
+</p>
+<p>
+It was quite a long story, that of his getting
+a perfect understanding with Liu, and Ned cut
+it as short as possible, merely saying that Liu
+had recognized his name, having heard his associates
+mention it frequently. Then the Chinese
+boy had procured the disguise and Ned had
+stuffed out the shoulders of the coat to give it a
+better fit.
+</p>
+<p>
+“I was observed by a half a dozen men, some
+Americans, some Chinamen, while getting in
+here,” Ned said, then, “but the disguise misled
+them. Now, the question is this: How are we
+going to get out?”
+</p>
+<p>
+“We’ll have to fight our way out?” asked
+Jimmie.
+</p>
+<p>
+“It won’t answer,” Ned replied. “They
+are too many for us.”
+</p>
+<p>
+Liu now came into the second cave and held
+up his hand for silence.
+</p>
+<p>
+“You’ll have to hide in the back chamber,”
+he said. “Chang is coming in.”
+</p>
+<p>
+“I thought this was the back chamber,”
+Jimmie said.
+</p>
+<p>
+“I suspect,” Liu said, “that there’s a chain
+of caves running through the divide. Come on!”
+<span class='pagenum pncolor'><a id='page_165'></a>165</span>
+</p>
+<p>
+Liu passed back to the west, removed a
+great box which stood against the rear wall, and
+disclosed an opening through which the patrol
+leader crawled. When the box was replaced
+Ned stopped and listened. What he heard was
+the click of a typewriter.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_166'></a>166</span><a name='chXIII' id='chXIII'></a>CHAPTER XIII.—OFF ON A DESPERATE MISSION.</h2>
+<p>
+What business calling for the use of a typewriter
+was being transacted under the main
+divide of the Rocky Mountains?
+</p>
+<p>
+Ned stood perfectly still in the darkness and
+listened. He could hear the click of the keys
+and nothing else. At length he moved stealthily
+forward over an even surface, feeling his way
+in order that he might not trip over some unseen
+obstruction and raise a racket in a tumble.
+</p>
+<p>
+Presently he came to a rug hanging at the
+end of the chamber in which he was. From the
+other side of the rug came a faint light. The
+noise of the keys was more distinct here, and
+the boy knew that he had at least located the
+operator.
+</p>
+<p>
+While he stood listening and undecided as
+to what course to pursue, the noise of the machine
+ceased and the operator—a young, well-dressed
+American—came toward him carrying
+a lighted candle in his hand. Ned crouched
+down in an angle of the wall and waited for him
+to pass.
+<span class='pagenum pncolor'><a id='page_167'></a>167</span>
+</p>
+<p>
+The boy was not quite so anxious now to
+leave the strange rendezvous in which he found
+himself. Some mischief greater than smuggling
+opium and Chinamen over the border might
+be carried on there. His work seemed to be
+growing on his hands!
+</p>
+<p>
+He had been sent to that district to investigate
+the cause of the frequent forest fires, and
+given an aeroplane in order that he might fly
+over the forests in making his observations.
+It seemed to him now, as he lay on his side
+against a wall of rock, waiting for the typist to
+pass with his light, that he was spending more
+time under the ground than in the air!
+</p>
+<p>
+The main range of the Rocky Mountains in
+the northern part of Montana is noted for its
+rugged and irregular formation. It is declared
+by some that the home of the original cave
+dwellers was here. Many of the great caÃąons are
+known to be honeycombed with openings almost
+large enough to hide a small city in.
+</p>
+<p>
+The typist moved straight ahead and his
+light disappeared from view. Then Ned advanced
+beyond the rug, which appeared to be
+of fine material, and flashed on his light. There
+was a table in the room, a couple of chairs, a
+row of pigeon-holes attached to the wall.
+<span class='pagenum pncolor'><a id='page_168'></a>168</span>
+</p>
+<p>
+On the table was a typewriter, in the pigeon-holes
+were folded papers, neatly ticketed and
+enclosed in rubber bands. Aside from the underground
+smell the place was tolerably comfortable.
+The air was damp and chilly, but Ned was well
+clothed and did not mind that.
+</p>
+<p>
+As has been said, the boy was now in no
+haste to leave the place. He believed that the
+mystery he had been sent out to solve would be
+solved there. For an hour or more he searched
+over the place, opening the folded papers and
+making a close examination of the typewriter
+and the stock of unused paper in the drawer of
+the table.
+</p>
+<p>
+At length, his examination completed, he
+passed back into the chamber behind the rug
+and listened at the opening through which he
+had entered. A sound of the steady beat of
+blows reached his ears at first, then a low
+whistle. That was Jimmie, he knew. The lad
+had a habit of whistling softly to himself, usually
+without time or tune.
+</p>
+<p>
+Waiting for a lull in the blows, he rapped
+softly on the box which backed up against the
+opening. Instantly the whistling ceased, and
+Jimmie’s voice was heard.
+<span class='pagenum pncolor'><a id='page_169'></a>169</span>
+</p>
+<p>
+“Come on out,” the boy said. “I’ve been
+kicking my heels against this box for an hour,
+waitin’ for you to signal back.”
+</p>
+<p>
+“Be sure there is no one watching,” Ned
+cautioned.
+</p>
+<p>
+He heard Jimmie walking away, then heard
+him coming back. In a moment the box was
+drawn away from the opening.
+</p>
+<p>
+“You’ve been in there long enough to dig
+through to China,” Jimmie said, as Ned stood
+by his side. “What did you find in there?”
+</p>
+<p>
+“A double keyboard typewriter,” grinned
+Ned.
+</p>
+<p>
+“Quit your kiddin’,” answered Jimmie.
+“You’ll be claimin’ next that you found a brass
+band in there.”
+</p>
+<p>
+Ned did not stop to explain to the boy all
+that he had discovered in the inner chamber.
+His work there seemed to be finished now, and
+he was anxious to get back to camp. There
+was no knowing what had been going on there
+during his absence.
+</p>
+<p>
+“Where is Liu?” he asked.
+</p>
+<p>
+“Watchin’ outside,” was the reply. “He’s
+my guard. Goin’ to shoot me if I try to get
+away.”
+</p>
+<p>
+“And the others?” asked Ned.
+<span class='pagenum pncolor'><a id='page_170'></a>170</span>
+</p>
+<p>
+“Don’t know,” replied Jimmie. “They
+herded a lot of Chinks an’ went off down the
+valley.”
+</p>
+<p>
+Liu now appeared in the entrance, bowed
+gravely to the boys, and stepped out on the
+ledge, with a Boy Scout challenge in the wave
+of his hand.
+</p>
+<p>
+“He’s all right!” Jimmie said. “You ought
+to see the breakfast he got up for me. That
+feller can cook—an’ then some!”
+</p>
+<p>
+“Call him,” Ned suggested, “and we’ll see
+if it is safe for me to go out.”
+</p>
+<p>
+“For you to go out!” repeated Jimmie.
+“For us to go out.”
+</p>
+<p>
+“I think you’d better remain here,” Ned
+replied.
+</p>
+<p>
+Jimmie looked at his chum in amazement.
+The light back there was not good, but Ned
+saw several questions in the boy’s eyes.
+</p>
+<p>
+“Liu can protect you, can’t he?” Ned asked.
+</p>
+<p>
+“That’s what I don’t know,” was the reply.
+“He will do his best, of course, but his best
+might not be good enough.”
+</p>
+<p>
+Ned was thinking fast. If he permitted the
+boy to leave, the fact of his escape would be
+likely to scatter the outlaws—and he very much
+wished to keep them together for a short time.
+<span class='pagenum pncolor'><a id='page_171'></a>171</span>
+</p>
+<p>
+“I think,” he said, “that we have found
+the men we want—with the goods. If you
+leave now they will make a quick getaway.
+You see that, don’t you?”
+</p>
+<p>
+“Of course,” was the reply. “An’ I see,
+too, that if I remain I’m the one that’s likely
+to make a quick getaway—to a country no one
+comes back from.”
+</p>
+<p>
+“There may be some other way,” Ned said,
+thoughtfully. “Give me a chance to think it
+over.”
+</p>
+<p>
+“Oh, I’ll stay, all right,” Jimmie went on,
+“if it will do any good. I guess they won’t eat
+me alive.”
+</p>
+<p>
+As he spoke the boy put his hand to his eyes
+and gave them a long rub.
+</p>
+<p>
+“There’s smoke in here,” he said. “Don’t
+you smell it?”
+</p>
+<p>
+“I was thinking of that,” Ned replied, anxiously.
+“There may be a fire in the caÃąon.”
+</p>
+<p>
+Regardless of consequences, Jimmie rushed
+to the ledge and looked out. The sun was no
+longer in sight, for a mist of smoke hung over
+the caÃąon and over the slope to the east.
+</p>
+<p>
+“There’s goin’ to be the biggest blaze ever!”
+Jimmie cried.
+<span class='pagenum pncolor'><a id='page_172'></a>172</span>
+</p>
+<p>
+Liu came to the side of the boys and pointed
+to the south.
+</p>
+<p>
+“The fire came through a gully over there,”
+he said. “I was watching it from here. It
+was not put out yesterday, and worked its way
+over the divide. When it gets to going strong
+here no one can live in this cavern. I’m going
+to get out.”
+</p>
+<p>
+“That’s the idea!” Jimmie cried.
+</p>
+<p>
+The caÃąon was a veritable fire trap. For
+years the boughs and the turp of the trees had
+been dropping down. Ned knew that the blaze
+would mount to the cavern and be drawn into
+it. The atmosphere of the place indicated
+openings at the rear which would serve as chimneys.
+</p>
+<p>
+“Oh, the devils!” Jimmie cried. “To set
+a fire like that!”
+</p>
+<p>
+“They didn’t set it, I tell you,” insisted Liu,
+speaking as if in the defense of his employers.
+</p>
+<p>
+“Who did, then?” demanded Jimmie, half
+angrily.
+</p>
+<p>
+“It came through from the other side, just
+as I told you,” replied Liu, with the utmost
+good nature. “There’ll be a pass through the
+range some day where the fire found its way
+through.”
+<span class='pagenum pncolor'><a id='page_173'></a>173</span>
+</p>
+<p>
+“But they set the fire on the other side,”
+Jimmie urged. “They set it for the purpose of
+burning our aeroplane an’ driving us out of the
+district. When we go out of the district they’ll
+go with us, wearin’ steel bracelets!” he added.
+</p>
+<p>
+“I rather think,” Liu said, “that they set
+the fires over there to draw the foresters, away
+from this section, and so protect their business.
+That is what they have been doing right along.”
+</p>
+<p>
+“Yes,” Ned said, “there has been a forest fire
+for every cargo of opium, for every gang of Chinamen,
+that has been brought in over the border.”
+</p>
+<p>
+“So that is the real trouble?” asked Jimmie.
+“How do you know so much about it?”
+</p>
+<p>
+Ned smiled and pointed to the slope to the
+east, where columns of fire were cutting their
+way through the timber.
+</p>
+<p>
+“It strikes me,” he said, “that now is a
+pretty good time for us to get out of this. The
+outlaws won’t come back so long as this danger
+exists, and we shall not be missed for a long time—or
+rather, Liu and Jimmie will not be missed.”
+</p>
+<p>
+“They’ll think we ran out to escape the heat
+and lost our lives in the fire,” Liu said.
+</p>
+<p>
+Ned stood hesitatingly at the mouth of the
+cavern while Liu gathered a few articles he
+wanted to take with him.
+<span class='pagenum pncolor'><a id='page_174'></a>174</span>
+</p>
+<p>
+“If I thought the fire would reach the cave
+when the big trees in the caÃąon get to going,”
+he mused, “I’d go back and get the papers—or
+more of them.”
+</p>
+<p>
+“It surely will get into the cave,” Liu said.
+“You see, the summit scoops down here quite
+a lot, and the timber line is almost to the top.
+The gulch below is quite high up on this elevation,
+still it is not so very high as compared
+with some of the summits to the north and
+south. So, you see, the timber line here is capable
+of getting up a good deal of a blaze, especially
+where the caÃąons are full of trees. The
+fire will come up here, all right.”
+</p>
+<p>
+Ned darted away, was gone a minute or so,
+and returned with hands full of folded papers.
+</p>
+<p>
+“What you got?” demanded Jimmie.
+</p>
+<p>
+Ned laughed but made no satisfactory reply.
+After stowing the papers away in the numerous
+pockets of his borrowed suit, he led the way
+down the ledge, away from the cave he had first
+seen in his fall down the caÃąon, and which had
+proved so profitable to his search.
+</p>
+<p>
+The air was now filled with smoke. The
+caÃąon below was not yet in full flame, but a
+column of destruction was creeping upon it from
+the south. It seemed to Ned that there were
+<span class='pagenum pncolor'><a id='page_175'></a>175</span>
+numerous small fires, though how this could be
+true he could not understand.
+</p>
+<p>
+The boys made their way along the ledge
+without coming upon any of the men who had
+occupied the cavern. It was evident that the
+few left after the departure of the men with the
+Chinamen had fled before the clouds of smoke.
+The ledge wound up on the plateau from which
+Ned had dropped the night before, and here they
+paused to decide on some course of action.
+</p>
+<p>
+The light breeze was from the west, so the
+fires below were in a measure protected from it
+by the bulk of the summit, but Ned knew that
+the heat would in time bring the air into the
+burning spaces with a rush, merging the little
+blazes into one gigantic one which might repeat
+the disasters of August, 1910.
+</p>
+<p>
+Now and then, from far to the east, there
+came a signal in the shape of a gunshot. The
+faithful foresters were at work there, trying to
+head off the advancing flames before they passed
+beyond control. The place to combat a forest
+fire, of course, is ahead of it, and not where the
+red line is running through the sputtering timber.
+</p>
+<p>
+“If I could get the aeroplane,” Ned said, as
+he looked over the country from the plateau, “I
+might get to the fighting line and do some good.”
+<span class='pagenum pncolor'><a id='page_176'></a>176</span>
+</p>
+<p>
+“Where is it?” asked Liu.
+</p>
+<p>
+“At the camp.”
+</p>
+<p>
+“The others won’t dare bring it out, of
+course?” asked Liu.
+</p>
+<p>
+“Doubtful,” Ned replied. “Frank has always
+taken a great interest in the machine, and
+was studying its mechanism when I left, but I
+don’t think he will attempt to operate it. He
+ought not to, anyway.”
+</p>
+<p>
+“If the men who left here to pinch the boys,”
+Jimmie said, “showed up at the camp, an’ Frank
+got a chance to mount the aeroplane, you bet
+your life he’s shootin’ through the air with it
+this minute, or hidin’ in some valley.”
+</p>
+<p>
+“But there were three of them,” Ned urged,
+“and all couldn’t ride.”
+</p>
+<p>
+“They’d try!” gritted Jimmie, “unless Pat
+got cold feet an’ run away.”
+</p>
+<p>
+Ned glanced up at the sky, now very thick
+with smoke, as the boy spoke. He looked with
+indifference at first, then with interest, then
+with anxiety. There was a shape moving up
+there, coming slowly toward the plateau.
+</p>
+<p>
+“There they are!” shouted Jimmie, whose
+attention had been attracted to the sky by Ned’s
+fixed gaze. “Frank’s runnin’ the machine. I’ll
+<span class='pagenum pncolor'><a id='page_177'></a>177</span>
+bet dollars to apples that he’ll dump her into
+the caÃąon when he tries to land here.”
+</p>
+<p>
+The aeroplane, indeed, looked as if there were
+an uncertain hand at the helm. She wavered,
+tipped in the air currents, dipped wickedly, circled
+staggeringly, but finally swooped down
+on the plateau and, more by good luck than
+good handling, settled down within a dozen feet
+of the lip of the caÃąon. Frank and Jack were
+aboard. Pat, they said, had taken to his heels
+at the first suggestion of his joining the others
+in the ride.
+</p>
+<p>
+Ned examined the machine carefully and
+found it in excellent shape, although the gasoline
+was getting low.
+</p>
+<p>
+“Better go an’ get some,” Jimmie suggested.
+</p>
+<p>
+Ned looked toward the line of smoke off to
+the east.
+</p>
+<p>
+“We can reach the firing line with what we
+have,” he said, in a moment, “and that may be
+sufficient for the present.”
+</p>
+<p>
+“What you goin’ to do?” demanded the boy.
+</p>
+<p>
+“Going to see if I can’t help fight this fire,”
+was the reply.
+</p>
+<p>
+“From here?” laughed Jack.
+</p>
+<p>
+Ned indicated a distant line of hills where
+the forest still stood green on the slopes.
+<span class='pagenum pncolor'><a id='page_178'></a>178</span>
+</p>
+<p>
+“We’ll fight the fire from there,” he said.
+“We can see the location well enough now, but
+the smoke will soon shut it out from here.”
+</p>
+<p>
+“What can we do when we get there?” asked
+Jack. “We are safe enough here. The smoke
+and heat may scorch us a little, but we’ll live
+through it, and that is more than we can say
+about the safety of the place you point out.”
+</p>
+<p>
+“Pat will be making his way here,” Ned said,
+“and you may as well remain here and meet
+him. I’ll take Frank and go over to the place
+where the foresters are fighting the blaze.”
+</p>
+<p>
+Jimmie was on his feet in an instant.
+</p>
+<p>
+“Me for the ride with you!” he shouted.
+</p>
+<p>
+“Some one may have to run the machine
+back,” Ned said. “You can’t do that, my little
+man, and Frank can, so Frank goes.”
+</p>
+<p>
+“I don’t see what you can do over there that
+the foresters can’t do,” Liu said.
+</p>
+<p>
+“There is no knowing how useful the aeroplane
+may be,” Ned said.
+</p>
+<p>
+Then the machine was rolled back as far up
+the plateau as possible, the boys took their seats,
+and then they were lost in the dense clouds of
+smoke in the sky.

+<h2><span class='pagenum pncolor'><a id='page_179'></a>179</span><a name='chXIV' id='chXIV'></a>CHAPTER XIV.—THE BATTLE IN THE AIR.</h2>
+<p>
+The smoke was driving fiercely through the
+green trees on the slope, and the line of fire was
+not far in the rear. Every moment the wind
+gained force, every minute the flames leaped
+higher and faster.
+</p>
+<p>
+The foresters felling trees and clearing a
+space at an advantageous point some distance
+in advance of the flames were working blindly,
+mechanically. The heat was intense, the smoke
+suffocating, irritating, blinding. The shirts of
+the workers were open at the throat, their coats
+had long ago been lost as they had been beaten
+back from one stand to another.
+</p>
+<p>
+Now and then a worker dropped senseless
+in his tracks, his lips cracked with the heat, his
+face blistered, his tongue lolling from his smarting
+mouth like that of an overworked horse.
+Then the men who were able to move and understand
+would carry him back to a spot of supposed
+safety and return to re-engage in the almost
+hopeless fight, the battle which the flames were
+winning in every charge and sally.
+<span class='pagenum pncolor'><a id='page_180'></a>180</span>
+</p>
+<p>
+The aeroplane, after a narrow escape from
+destruction, landed on a little rise of ground
+back of the working line when the wind lulled
+for an instant, and hope shone in the faces of
+the astonished men who gathered about to greet
+the unexpected arrivals.
+</p>
+<p>
+“We can master it,” Green, the leader, said,
+after many questions had been asked and answered,
+“if we can be supplied with water. We
+wasted our supply wetting our clothes a long
+time ago, and are suffering.”
+</p>
+<p>
+“Get us water,” shouted another, “and we’ll
+win yet.”
+</p>
+<p>
+“There’s a spring three miles away,” Green
+went on, speaking in Ned’s ear, for the roaring
+of the flames drowned all ordinary conversation.
+“If you can take our water bottles there and
+fill them we can beat this blaze. If you can’t
+we’ve got to retreat and let the whole district
+burn over.”
+</p>
+<p>
+“I have very little gasoline,” Ned replied,
+“but I’ll try.”
+</p>
+<p>
+“We sent two men out not long ago,” Green
+continued, thrusting his scorched face close to
+the boy’s. “We sent them out with water bags,
+but there are no trails, and It will take them
+hours to make the spring and return. With
+<span class='pagenum pncolor'><a id='page_181'></a>181</span>
+your aeroplane you ought to do it within half
+an hour.”
+</p>
+<p>
+“Fire fighters marooned without a supply of
+water, or a trail cut to a spring!” shouted Frank,
+scornfully. “Great head some one in authority
+has!”
+</p>
+<p>
+“There are no trails, no telephones, no
+horses!” cried Green. “It looks as if the government
+sent us here to die. Hurry up with
+that water.”
+</p>
+<p>
+“If the gasoline holds out,” Ned said, loading
+a dozen water bags on the machine, “I’ll be back
+here in less than half an hour, bar accidents.”
+</p>
+<p>
+“There is plenty of gasoline back there in
+the shanty,” cried Green. “We have been
+using it lately in starting back fires, but the wind
+is now too strong for that. Get a move on, and
+take all you want.”
+</p>
+<p>
+In a short space of time, but not without
+great risk, the tanks of the aeroplane were filled,
+and then Ned took in the general situation in
+the sky. The wind was blowing in puffs, but
+it was certain that a miniature tornado was at
+hand. He thought he could reach the spring,
+which had been described as lying to the southeast,
+but was not certain that he could make
+his way back.
+<span class='pagenum pncolor'><a id='page_182'></a>182</span>
+</p>
+<p>
+He believed, however, that by flying either
+very low or very high up, so as to get all the protection
+possible from the mountain, or escape
+the sweep of wind just above the fire, he might
+be able to bring in one load of water before the
+worst of the wind storm came. He knew that
+it was an almost unheard of thing to even try
+to navigate the air in such a gale, but human
+lives were at stake, and he decided to try.
+</p>
+<p>
+“You’ll have to help me up against this
+wind,” Ned said to Green. “If I start with the
+air current I’ll be carried too far to the east before
+my power begins to become effective. If
+I can hold my own against the wind until I get
+above the smoke I think I can win the game.”
+</p>
+<p>
+It was a desperate expedient, but it appeared
+to be the only possible one. If the men had
+water they might succeed in stopping the fire
+and saving millions of dollars worth of timber.
+If the fire gained the upper hand they might
+lose their lives. The men cleared and smoothed
+a path for the run of the wheels, by great exertion
+sent the machine along at good speed,
+and then stood and watched it with anxiety
+depicted in their faces.
+</p>
+<p>
+The great white bird quivered in the face of
+the wind, but the motors were true to their duty
+<span class='pagenum pncolor'><a id='page_183'></a>183</span>
+and the rudder held. To turn about in the face
+of that rush would be impossible, so Ned worked
+his levers guardedly and kept the wings as level
+as he could. Now and then a swirl of heated
+air would shake the hopes of those watching below,
+but in the end the aeroplane drifted slowly
+ahead, up, higher up, and was lost in the smoke.
+</p>
+<p>
+“The lad is worth his weight in gold!”
+shouted Green. “He’ll do it! I know he’ll do
+it!”
+</p>
+<p>
+“Powerful motor,” one of the foresters said.
+“When we saw the machine last she was actually
+holding her own against the wind.”
+</p>
+<p>
+This was, indeed, the fact, but the wind was
+not as strong in the higher levels as at the upper
+limit of the heat from the fires. A great fire
+usually brings a great wind, as those who witnessed
+the burning of Chicago and San Francisco
+well know. The hot air rises, forming a
+partial vacuum, and the colder air rushes in.
+</p>
+<p>
+Ned and Frank gained the spring, filled their
+water bags and started back. It was no easy
+task to land near the spring in that whirl of wind,
+nor yet an easy task to get the aeroplane into
+the air again, but the feats were accomplished.
+Often after that exciting day the boys declared
+that they had no idea how they ever did it.
+<span class='pagenum pncolor'><a id='page_184'></a>184</span>
+</p>
+<p>
+“We were excited,” Frank would say, “and
+took chances, everything worked in our favor,
+and we loaded the water. We knew that lives
+were at stake, and it seemed that we had the
+strength of a score of men, and the cool heads
+of men far beyond all excitement. I never saw
+anything like the way Ned handled the levers.
+The wings and the rudders seemed to me to
+work on a brain suggestion rather than on a
+movement of the levers.”
+</p>
+<p>
+But the most difficult part of the journey
+still remained to be accomplished after the water
+had been secured. The ’plane was much heavier
+and did not respond so readily to the hand
+of the driver, and the return course was quartering
+against the wind. Ned, however, did
+not attempt to move directly toward the destination
+he sought.
+</p>
+<p>
+Instead he sailed off to the south, working
+west as much as possible. He tacked as a yacht
+tacks in the wind and came near upsetting several
+times. He found it impossible to sail low
+on account of the eddies and currents created
+by the heat, and so lifted the machine far up
+into the air. It was better sailing there, and
+he managed to get as far west as he thought
+necessary.
+<span class='pagenum pncolor'><a id='page_185'></a>185</span>
+</p>
+<p>
+But he could not see the landing place.
+Below was an ocean of smoke, the waves heaving
+in the touch of the wind, the edges now and
+then tipped with flame. Above the sun smiled
+at him, and the birds flew excitedly about, peering
+down at the threatening roll of clouds.
+</p>
+<p>
+“I’m afraid,” Frank said, grasping an
+upright and clinging to the water bags.
+</p>
+<p>
+“I never was so frightened in my life,” Ned
+called back, lifting his voice so that it might be
+heard above the snapping of the motors.
+</p>
+<p>
+“I didn’t finish,” Frank called back, his
+heart thumping loudly. “I wanted to say that
+I was afraid we’d sweep past the workers when
+we descended into the smoke and the swifter
+breeze near the earth.”
+</p>
+<p>
+“I said just what I wanted to say,” Ned
+answered. “I never was half so scared in all
+my life.”
+</p>
+<p>
+Yet his hand on the lever was steady, his
+brain was as cool as if he had been sitting in the
+Wolf Patrol club room in New York. He knew
+that the dip of a wing a foot lower than he intended
+might send them both into the blazing forest
+below. He was afraid, but not with a shrinking,
+physical fear, but afraid because he understood
+the peril he was in—because he knew that
+<span class='pagenum pncolor'><a id='page_186'></a>186</span>
+upon his efforts depended the lives of the heroes
+in the heated hell below.
+</p>
+<p>
+“We’ve got to go into that mess of smoke, I
+suppose?” shouted Frank.
+</p>
+<p>
+“There is no other way,” Ned called back.
+“We’ve got to dip down low enough to see the
+line of fire and take our chances on landing where
+the fighters are. You understand that they are
+farther to the east than when we left them?”
+</p>
+<p>
+“Of course they have been driven back,”
+Frank said. “I never thought of that. We
+may not be able to find them at all.”
+</p>
+<p>
+Ned shut his teeth and settled his jaw.
+</p>
+<p>
+“We’ve got to find them,” he said.
+</p>
+<p>
+A long, sullen roaring, like the beating of
+waves on a beach in a storm, now reached the
+boys’ ears, even shutting out the chattering of
+the motors. It came from the west, and passed
+along, as it seemed, below the level held by the
+aeroplane, now high up in the air.
+</p>
+<p>
+“If we don’t get down there pretty soon,”
+Ned said, shouting, “we will be too late. That
+wind will join the different fires and make one
+roaring mass of the whole northwest. I wish
+I knew just how far the foresters have been
+driven back.”
+<span class='pagenum pncolor'><a id='page_187'></a>187</span>
+</p>
+<p>
+“Do you know where to look for them, north
+or south?” asked Frank.
+</p>
+<p>
+“There is a peak to the west and one to the
+east,” was the reply. “They are on a line with
+the two. But the trouble is that we can’t see
+the peaks after we drop down into the smoke.”
+</p>
+<p>
+“There appears to be a little lull in the wind
+now,” Frank said, shutting his lips tight, as a
+man does when about to make a sudden plunge
+into unknown waters.
+</p>
+<p>
+The remark was suggestive. Ned knew by
+it that his chum had braced himself for the dash.
+</p>
+<p>
+“Here we go, then,” Ned replied. “Remember
+that we’ll go about eighty miles an
+hour when I turn the motor on full head, and
+that we can’t be more than five miles from the
+spot where we left them, so keep your eyes out.”
+</p>
+<p>
+The aeroplane dipped gracefully as Ned
+touched the lever. In a minute the boys were
+surrounded by smoke. It was hot smoke, too,
+and made breathing difficult. Their eyes smarted
+until their faces were wet with nature’s protest
+against such irritation of the organs of sight.
+The chuck-chuck, snap-snap of the motors was
+in their ears, the seats they occupied—frail
+rests between life and death—shivered under
+the pulsations of the machine.
+<span class='pagenum pncolor'><a id='page_188'></a>188</span>
+</p>
+<p>
+Now and then the aeroplane dipped frightfully,
+but the wings and the rudders brought it
+back again.
+</p>
+<p>
+“Can you see the earth yet?” asked Frank,
+In an awed tone, which sounded like a whisper
+in that clatter.
+</p>
+<p>
+“We seem to be over the fire,” Ned returned.
+</p>
+<p>
+And that was all. There was no need of
+conversation. In all their lives they would
+never be so near to a frightful death as they were
+then.
+</p>
+<p>
+First they caught sight of a rocky ridge.
+Ned knew where that was, and realized that
+he was still in the direct line of the workers.
+Beyond this ridge, he knew, was a valley, so
+he must drop down. The workers were on a
+level beyond the valley, a great plain of fir
+and pine between gigantic ranges of the Rocky
+Mountains.
+</p>
+<p>
+The aeroplane trembled as she dropped, swiftly,
+apparently straight down. Frank grasped
+his upright and prepared to spring out of the
+wreckage when it fell, if there was anything to
+fall from after the trees had had their way with
+the frail machine.
+</p>
+<p>
+The smoke was blinding. Nothing could be
+seen but smoke for a time. Then the dark gray
+<span class='pagenum pncolor'><a id='page_189'></a>189</span>
+clouds turned red, and Ned knew that he was
+nearing the advance line of the fire, and that it
+was mounting to the very tops of the giant trees
+on the plain—or elevated plateau, rather, for,
+though comparatively smooth of surface and
+heavily timbered, it was far above sea level.
+</p>
+<p>
+If you look on an enlarged map of northern
+Montana you will see that the Rocky Mountains
+do not consist of one great, massive range.
+There are ridges and valleys, and plateaus extending
+for hundreds of miles along the British
+frontier. There are peaks from which the snow
+never disappears, and there are timber lines
+which crawl almost to the summit of other peaks.
+There are fertile valleys where cattle grow fat,
+and great gorges where beasts of prey await
+their victims in thickets.
+</p>
+<p>
+It is the timber on this great stretch of country
+that the United States government is trying
+to save.
+</p>
+<p>
+The heat was blistering now, and Ned feared
+for the safety of his gasoline tanks. At a motion
+from him Frank removed his coat, carefully, for
+a slight movement in the air is sometimes productive
+of disastrous results, placed it over the
+tanks, after a great effort, and managed to saturate
+it with water from one of the bags.
+<span class='pagenum pncolor'><a id='page_190'></a>190</span>
+</p>
+<p>
+Through the smoke a line of tree tops now
+came into view, low down, and the boys knew
+that they had passed the fire line. Ned tried
+to slow down, but found that he must keep the
+motors going in order to retain control of the
+machine.
+</p>
+<p>
+“There’s a clear space ahead!” Frank
+shouted, and Ned dropped. Then a giant trunk
+obtruded itself, and the boy tried to dip and
+whirl so as to dodge it, but the pressure of the
+wind was too strong.
+</p>
+<p>
+The machine headed straight for the tree,
+which seemed to Frank to be about a thousand
+feet high.
+</p>
+<p>
+“Hang on to the first thing that comes to
+your hands if she strikes!” Ned shouted. “But
+stick to the ’plane as long as she is clear. There
+may be a current of air which will sweep us away
+from that tree.”
+</p>
+<p>
+“Here’s hoping!” Frank gasped back, and
+then the smoke shut out the view, making the
+situation doubly dangerous.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_191'></a>191</span><a name='chXV' id='chXV'></a>CHAPTER XV.—TOLD BY THE FOREST RANGER.</h2>
+<p>
+The rangers, almost exhausted, were fighting
+the fire desperately, hoping against hope, when
+the cyclone—it amounted at times almost to
+that—struck the forest. Then they knew that
+the fight was lost for the time being.
+</p>
+<p>
+It was now a question of escaping from the
+flames they had been battling with. The chief
+foresters knew very well that there was a way
+to safety, but they had under their command
+many rangers who had joined the service merely
+for the adventures they anticipated meeting,
+and these, they understood, would be hard to
+manage.
+</p>
+<p>
+When the order came to drop everything and
+fall back some of the new men accused those in
+authority of cowardice and kept on in the course
+mapped out for them under entirely different
+conditions. Two of them even insisted on starting
+back to the rough shanty and preparing
+dinner. They lost their way in the blazing
+inferno, and their bones were found two weeks
+<span class='pagenum pncolor'><a id='page_192'></a>192</span>
+later, at the foot of a tree which had been
+burned into a stub, but which had not fallen.
+</p>
+<p>
+When the danger became apparent to Green
+who was in charge of the company found by
+Nestor, he ordered his men into a “burn” of
+half a dozen acres in extent. By “burn” is
+meant a patch of forest which has been cleared
+by fire the previous year. This “burn” was
+entirely stripped of trees. The fire had done
+its work well, but had been checked before
+spreading.
+</p>
+<p>
+The men could hear trees falling as they
+dashed along. The fire was screaming, the wind
+whistling and roaring. Coals of fire, driven like
+arrows by the wind, hit the men in the back as
+they rushed toward safety. At last the “burn”
+was gained, and the men threw themselves face
+down on the ground. At the eastern edge there
+were large logs which had not been entirely
+consumed, and some of the men lay down
+behind them.
+</p>
+<p>
+The air was so hot that it cut the lungs like
+acid. Above, across the old “burn,” streamed
+a river of flame, now racing like a mountain
+torrent, now dropping sullenly back to the west,
+like a fiery ceiling which had been rolled away.
+On such occasions the fainting foresters below
+<span class='pagenum pncolor'><a id='page_193'></a>193</span>
+could catch a breath of fresh air and a hazy
+view of the sky.
+</p>
+<p>
+Some of the men, half crazed by their sufferings,
+arose to their feet and shook clenched hands
+at the blazing forests, at the brassy sky, and the
+green hills away to the east. Green crept from
+one to another and whispered that the only hope
+of life lay in keeping on the ground.
+</p>
+<p>
+Once when he was creeping toward a man
+who was moaning in anguish and despair he
+turned his eyes upward to the sky, clear for an
+instant, for the wind was wayward after a time,
+and saw a speck sweeping out of the west, dropping
+lower and lower, whirling in the wind, racing
+like an express train.
+</p>
+<p>
+“Dan,” he whispered to the man he was trying
+to comfort, “get a brace! There’s no use
+of giving up now. Why, man, the fight is won,
+and Nestor is coming back with water!”
+</p>
+<p>
+“Impossible!” grunted the other. “Impossible—in
+this wind!”
+</p>
+<p>
+“Then look,” Green said.
+</p>
+<p>
+A sheet of flame swept over the “burn,” lay
+upon it for an instant like a red-hot roof, and
+then warped and twisted itself away.
+</p>
+<p>
+“I see,” Dan said, looking into the sky again,
+“but he can’t land. Impossible—in this storm!”
+<span class='pagenum pncolor'><a id='page_194'></a>194</span>
+</p>
+<p>
+“Wait and see!” Green said, and sank back
+to the earth.
+</p>
+<p>
+The aeroplane circled, high up, like a bird
+seeking its prey in the burning forest. The
+wind was tolerably steady at that height, but
+Ned knew that when he came into the lower
+current he would meet conditions which he
+could not understand.
+</p>
+<p>
+“There’s a place to drop!” Frank shouted
+to him, pointing ahead to the “burn,” which
+seemed only a few yards away.
+</p>
+<p>
+The aeroplane had missed the tree which had
+threatened it by an inch, and had turned upward
+again, for there were other trees in the
+way of a descent there. The “burn” was the
+first free spot that had been observed, and,
+besides, it lay inside the line Ned had figured as
+leading to the foresters.
+</p>
+<p>
+“Hang on!” Ned cried.
+</p>
+<p>
+The aeroplane plunged down, almost vertically,
+and Frank felt as if he was standing on
+his head.
+</p>
+<p>
+“Don’t jump when it strikes the ground,”
+Ned commanded.
+</p>
+<p>
+Watched by a score of anxious eyes—for the
+foresters under Green had all been told of the
+coming relief—the aeroplane shot down, struck
+<span class='pagenum pncolor'><a id='page_195'></a>195</span>
+the ground at the center of the “burn,” rolled
+swiftly for a few yards, and stopped. At that
+moment the space above filled with flame.
+</p>
+<p>
+Both boys threw themselves on the ground
+and waited. When the fierce gust was over the
+men gathered about them eagerly.
+</p>
+<p>
+“Did you make it?” asked Green.
+</p>
+<p>
+“Yes,” Ned replied. “Get the bags out
+and distribute the water. Don’t let the men
+waste it.”
+</p>
+<p>
+“I’ll see to that,” cried Green.
+</p>
+<p>
+Without the water, without the cooling sips,
+without the wet cloths held over nose and mouth,
+without the saturated sponges laid on scorched
+heads, the men would have died there in the
+forest. Presently, when the consumption of the
+timber to the west reduced the heat, when the
+wind quieted down in a measure, they were
+ready for another fight with the flames, and it
+was owing largely to their exertions that the
+fire was extinguished before millions of acres
+had been burned over.
+</p>
+<p>
+“It is a dream!” Green exclaimed, that afternoon,
+as he stood by Ned and the aeroplane.
+“I don’t believe yet that you did it.”
+</p>
+<p>
+“I don’t see how I did,” laughed Ned.
+“Anyhow, I’m sure I couldn’t do it again. I
+<span class='pagenum pncolor'><a id='page_196'></a>196</span>
+guess Providence took the matter into his own
+hands. Honestly, I do not believe any human
+strength or skill could do what was done with
+the aeroplane to-day. It was a miracle.”
+</p>
+<p>
+“I know of a nervy boy who had something
+to do with the miracle,” said Green.
+</p>
+<p>
+Ned was naturally anxious regarding Pat,
+Jack and Jimmie, but believed they would show
+up in good form whenever he got back to the
+vicinity of the place where they had been left.
+When the boys were in camp with the rangers
+that night, Ned asked Frank about Pat’s idea
+of safety after refusing to go up in the aeroplane.
+</p>
+<p>
+“He said he would stay about the valley,”
+Frank replied. “There is plenty of provisions
+there, you know, and Pat is quite long on the
+eats,” he added, with a laugh.
+</p>
+<p>
+“And Jack and Jimmie will be sure to hang
+about the neighborhood of the caves,” Ned said.
+“The Chinese boy, Liu, will be able to care for
+them. If there is enough gasoline in the tanks,
+I may go back to the valley to-night.”
+</p>
+<p>
+“You’d better get some sleep to-night,”
+Frank advised. “I don’t know how long it
+has been since you settled down for a night
+of it. If you keep your brain working right
+you’ve got to sleep.”
+<span class='pagenum pncolor'><a id='page_197'></a>197</span>
+</p>
+<p>
+“I really ought to go to San Francisco,” was
+the astonishing reply to this advice. “I have
+work to do there.”
+</p>
+<p>
+“What work?” demanded Frank.
+</p>
+<p>
+“You see,” Ned answered, “we have done
+nothing yet, except discover a crime with which
+we are supposed to have nothing to do. We
+have brought a little water for the fire-fighters,
+but we came here for a certain purpose, and we
+have not made good as yet. Perhaps, when I
+get to Frisco, I can hunch my wits, as the baseball
+fans say, and report good progress.”
+</p>
+<p>
+“I don’t understand what you mean,”
+Frank said.
+</p>
+<p>
+“I am not sufficiently sure of my ground to
+attempt an explanation now,” Ned replied.
+</p>
+<p>
+“Of course,” Frank said, thoughtfully,
+“there’s the murder case you went to Frisco
+about before. You might look that up again,
+but I can’t see where that has any bearing on
+this forest fire business.”
+</p>
+<p>
+“You may be surprised,” Ned said, “when
+the end comes. Somehow, I have an idea that
+the two crimes dovetail into each other.”
+</p>
+<p>
+“Nothing stirring!” laughed Frank. “They
+don’t seem to me to match. Still, you may
+have information I do not possess.”
+<span class='pagenum pncolor'><a id='page_198'></a>198</span>
+</p>
+<p>
+An hour later, after the not very elaborate
+supper had been eaten, Green came to the little
+tent which had been set aside for Ned and Frank.
+He had not wholly escaped the dangers of the
+day unscathed. There were burns on his hands
+and face, and one of his feet was bandaged.
+</p>
+<p>
+“Shoe burned through,” he said, shortly.
+“I shall have to walk with a crutch for several
+days.”
+</p>
+<p>
+“You won’t like that,” Ned suggested.
+</p>
+<p>
+“No, indeed,” was the reply, “especially as
+I would like to be moving about in order to see
+what has happened to the other boys.”
+</p>
+<p>
+“Have you heard from any of the other
+groups?” asked Ned.
+</p>
+<p>
+“Howard came in from the north,” was the
+reply. “Three men killed up there. The fire
+caught them unawares. One of my men has
+gone south, but it will be some hours before I
+hear from him.”
+</p>
+<p>
+“I am afraid there were several lives lost,”
+Ned said. “In the morning I’ll fly about and
+see what I can learn.”
+</p>
+<p>
+“What I came here to talk about,” Green
+said, after a pause, “is this. I want to know
+what you think of the Chinks?”
+</p>
+<p>
+“The Chinese fire-fighters?” asked Ned.
+<span class='pagenum pncolor'><a id='page_199'></a>199</span>
+</p>
+<p>
+Green laughed quietly for a moment before
+replying. Then:
+</p>
+<p>
+“They told you that, did they?”
+</p>
+<p>
+Ned nodded. He wanted to jump into the
+subject without waiting for Green to have his
+say, for he was greatly interested, but prudence
+told him to listen to the forester first.
+</p>
+<p>
+“Yes,” he said. “They told me that.”
+</p>
+<p>
+“Also that they were foresters—the men who
+told the story about the Chinks, I mean?”
+</p>
+<p>
+“Yes, one of them claimed to be in charge of
+this district.”
+</p>
+<p>
+“Well, you know better than that now, so
+there is no use in talking about that. You saw
+some of the Chinks?”
+</p>
+<p>
+“Certainly. I even had the honor of visiting
+their residence.”
+</p>
+<p>
+Frank laughed, wondering what sort of a
+story Ned would have to tell him when they
+were alone again.
+</p>
+<p>
+“It is a wonder you ever got out again,”
+Green said.
+</p>
+<p>
+“I left under the excitement of the fire,”
+Ned said. “It was easy enough.”
+</p>
+<p>
+“Do you know where the Chinks have gone?”
+asked Green.
+</p>
+<p>
+“I think I do,” was the reply.
+<span class='pagenum pncolor'><a id='page_200'></a>200</span>
+</p>
+<p>
+“To San Francisco?”
+</p>
+<p>
+“Yes, some of them. Others to Portland,
+I think.”
+</p>
+<p>
+“Smuggled in?”
+</p>
+<p>
+“Of course, though it seems odd that they
+should want to cross the border so far away from
+civilization. It must be expensive getting them
+in over such a route.”
+</p>
+<p>
+“The men at the bottom of the game are
+watched,” Green said. “Watched so closely
+that they are obliged to keep out of the actual
+work and do their business through unsuspected
+channels. After this place has been raided they
+will try some other point.”
+</p>
+<p>
+“You know what has been going on then?”
+asked Ned, surprised that the matter, as understood
+by the forester, had not been reported to
+him by the Secret Service man in San Francisco.
+</p>
+<p>
+“Yes,” was the reply.
+</p>
+<p>
+“And you have reported to your superior officers?”
+</p>
+<p>
+Green nodded, and Ned began to feel provoked
+at the strange attitude taken by the
+government in the matter. Surely he should
+have been posted as to conditions in the district
+before being sent on.
+<span class='pagenum pncolor'><a id='page_201'></a>201</span>
+</p>
+<p>
+“Why wasn’t I informed of this new element
+in the case?” he asked.
+</p>
+<p>
+“Well,” Green replied, “the officials have
+an idea that the men who are running the Chinks
+and the opium in are the men who are responsible
+for the forest fires. In fact, I have so reported
+to them for a long time.”
+</p>
+<p>
+“Go on,” the puzzled boy requested.
+</p>
+<p>
+“You see,” Green continued, “I might go
+and pick up a couple of dozen Chinks almost
+any month, and capture a lot of opium, and
+arrest a few men caught with the goods on, but,
+don’t you see, that wouldn’t end the game?”
+</p>
+<p>
+“I see that,” Ned answered.
+</p>
+<p>
+“There is a man at the head of this game who
+is working from behind the scenes somewhere,”
+Green hastened to say. “I don’t know who he
+is. The officials at San Francisco don’t know
+who he is, or where he is. The big guns at
+Washington know just about as much regarding
+the head center of the game as we do. Well,
+that is what you were sent here for—to get down
+to cases, as I used to say on South Clark street,
+Chicago.”
+</p>
+<p>
+“It was thoughtful of them not to interrupt
+the game until I got here,” Ned said.
+<span class='pagenum pncolor'><a id='page_202'></a>202</span>
+</p>
+<p>
+“Yes, I thought so,” Green went on. “I
+thought that any man, or boy, coming here to
+get to the bottom of this thing would want us
+to leave a few ropes hanging out for him to climb
+down. You found ’em.”
+</p>
+<p>
+“Yes, I found them,” Ned replied. “I
+found the counterfeit foresters and the Chinks,
+as you call them, and I found something else.”
+</p>
+<p>
+“That is what we expected you would do,”
+Green said, after a moment’s hesitation. “We
+wanted you to begin without pointers, with a
+brain free of all the unsuccessful schemes which
+have been worked. You see, I know a great
+deal about it, my boy,” he added with a laugh.
+“I knew, days ago, that you would be here.
+When I saw the aeroplane in the sky I knew
+who was in charge of it.”
+</p>
+<p>
+“What is the next move?” asked the boy.
+</p>
+<p>
+“That is for you to say,” was the reply. “I
+am under orders to follow any reasonable instructions
+from you. It is for you to suggest something.”
+</p>
+<p>
+“Well,” Ned said, “that brings me to a point
+I was studying over when you came in. I was
+wondering if you would detail men to do certain
+things for me.”
+<span class='pagenum pncolor'><a id='page_203'></a>203</span>
+</p>
+<p>
+“Sure I will. If Washington has confidence
+enough in you to put you in charge of the blindest
+case in history, why shouldn’t I have equal
+confidence in you? You bet I’ll be there with
+the oxen when you give the word.”
+</p>
+<p>
+“I thank you,” Ned replied. “What I
+want now is men enough to guard two points.
+One is a cave near Lake Kintla, and the other is
+the cavern where the Chinese have been hiding.”
+</p>
+<p>
+“How many men?” asked Green.
+</p>
+<p>
+“Two to each place. If there is need of
+more, others should be ready to assist.”
+</p>
+<p>
+“I wish you all success,” Green said, after
+the details of the surveillance had been arranged.
+“We have located the tools, and now it is for
+you to let down to bed rock. The government
+wants the headpiece of this game, and believes
+that you can put your finger on him. Half a
+dozen inspectors have failed, but I have faith
+in you, boy.”
+</p>
+<p>
+“Well,” Ned replied, “I am glad of your confidence,
+and thankful for the help you promise,
+and will only say that the man behind the
+scenes will soon be brought out. I think I know
+his ‘cue’!” he added, with a laugh.
+</p>
+<p>
+“Already?” asked Green.
+<span class='pagenum pncolor'><a id='page_204'></a>204</span>
+</p>
+<p>
+“I am only expressing confidence in the
+clues I now hold,” Ned said in reply. “It may
+be that the next clues I find will point the other
+way.”
+</p>
+<p>
+Green shook hands with the boys and went
+to his tent. It was a clear night up above the
+mountain tops, but down where the boys were
+the smoke of consumed forests lay on the ground
+like the gray ghost of fallen trees. Off to the
+west the summit of the Rocky Mountains—or
+one of the summits—lifted itself above the
+smudge, standing like a giant up to his neck in
+gray dust.
+</p>
+<p>
+“Over there,” Frank said, “is Pat—hungry,
+if you want to know, and nearer are Jack and
+Jimmie. I wish we could hear from them.”
+</p>
+<p>
+“If the ground wasn’t still red hot back
+there,” Ned said, “Jimmie would be sure to
+find us.”
+</p>
+<p>
+“By the way,” Frank said, presently, “what
+did you mean when you told Green that you
+had a ‘cue’ which would bring out the man
+behind the scenes?”
+</p>
+<p>
+“I meant that I have blundered on a clue
+which promises well,” was the reply. “And
+now,” he said, yawning, “I’m going to bed.
+Rather warm, but I think I’ll sleep, all right.”
+<span class='pagenum pncolor'><a id='page_205'></a>205</span>
+</p>
+<p>
+In five minutes Ned was sound asleep and
+Frank was about to lie down by his side when
+Green made his appearance. The forester noted
+the sleeping boy and laid a finger on his lips.
+</p>
+<p>
+“Let him sleep,” he said. “And come out
+here and see if you know anything about the
+fellow that is tampering with the aeroplane.”
+</p>
+<p>
+“What is he doing to it?” whispered Frank.
+</p>
+<p>
+“Acts like he was preparing to take a trip
+in it,” was the reply.
+</p>
+<p>
+The words were followed by the rattle of the
+motors.
+</p>
+<h2><span class='pagenum pncolor'><a id='page_206'></a>206</span><a name='chXVI' id='chXVI'></a>CHAPTER XVI.—HOW A CAT TREED A WOLF.</h2>
+<p>
+Smoke still hung over the “burn.” Now
+and then it was swept aside by a gust of wind
+which seemed now to blow out of the east, and
+so did not come sizzling with the heat of burned
+forests. The general effect, however, was that
+of a heavy, stifling fog, and Green and Frank
+crept along toward the aeroplane with their
+hands held out before their faces.
+</p>
+<p>
+The clatter of the motors had ceased, but
+the tap-tap of steel on steel was faintly heard
+as they neared the machine. Occasionally the
+worker, whoever he was, ceased his tapping, as
+if listening.
+</p>
+<p>
+“He’s got his nerve with him,” Frank whispered,
+as they moved along.
+</p>
+<p>
+“How did he get here?” asked Green.
+“That is the question that is troubling me.”
+</p>
+<p>
+Presently the two came up so that the figure
+of the man could be discerned, standing before
+the bulk of the planes. Green sprang forward
+and seized him by the arm. For an instant it
+<span class='pagenum pncolor'><a id='page_207'></a>207</span>
+seemed as if the capture would be made without
+a struggle, then a shot was fired and a crouching
+figure leaped away.
+</p>
+<p>
+Frank saw the forester fall and leaped toward
+the retreating figure. The race in the
+darkness, caused by the pall of smoke which
+followed, was short, for Frank was a noted runner
+and soon overhauled the fugitive. He did not
+attempt to take hold of the man as he came up.
+He knew that such a course might mean an unequal
+contest, for he was only a boy.
+</p>
+<p>
+Instead, he dropped to the ground and caught
+one of the runner’s ankles in both hands. Naturally
+the fellow plunged to the ground head-first.
+He turned quickly and leveled a revolver.
+There was no warning. The shot came instantly,
+the bullet passing over the boy’s head as he
+dropped upon the prostrate figure.
+</p>
+<p>
+With the hand which held the weapon held
+closely to the ground, Frank struggled with the
+fellow for an instant, filling the heavy air with
+his cries for assistance. The first shot had been
+heard by the sleepers, and help was at hand
+immediately. The captive was neatly tied by
+the light of Frank’s flashlight, and the foresters
+gathered about, still rubbing their eyes.
+</p>
+<p>
+The “burn” was not all in darkness all the
+time, for the glare of the smouldering embers to
+<span class='pagenum pncolor'><a id='page_208'></a>208</span>
+the west lighted the place fairly well. Only
+for the smoke the ruddy light would have made
+a pretty good illumination. When the fellow
+was lifted to his feet an exclamation of astonishment
+came from the group about him.
+</p>
+<p>
+“Sawyer!” some one cried.
+</p>
+<p>
+The prisoner dropped his chin for a moment,
+as if studying out some difficult proposition,
+then faced the others sheepishly.
+</p>
+<p>
+“I thought I could get away with it,” he
+said.
+</p>
+<p>
+A cry now came from the men who had hastened
+to Green’s assistance.
+</p>
+<p>
+“He’s dead, I guess,” the voice said.
+</p>
+<p>
+“I didn’t shoot to kill,” Sawyer exclaimed.
+“He can’t be dead.”
+</p>
+<p>
+“Why did you shoot at all?” demanded one
+of the rangers, approaching Sawyer with threatening
+fists.
+</p>
+<p>
+“He was in my way,” was the sullen reply.
+“I have always wanted an aeroplane, and I
+thought this a good time to get one.”
+</p>
+<p>
+“Did you injure the machine in any way?”
+asked Frank, as Sawyer stood gazing furtively
+from face to face, his black eyes showing fear.
+</p>
+<p>
+“When I found I couldn’t get it off,” was
+the reply, “I loosened some of the burrs. It
+can be repaired easily enough.”
+<span class='pagenum pncolor'><a id='page_209'></a>209</span>
+</p>
+<p>
+“That is more than can be said for you, if
+you have killed Green,” one of the men declared,
+shaking a fist at the prisoner. “If he’s dead
+you’ll be hauled up on one of these trees.”
+</p>
+<p>
+“You wouldn’t dare do that!” Sawyer cried.
+</p>
+<p>
+“Wouldn’t we?” cried the other. “You’ll
+see when we know whether he will live or not.
+How is it, boys?” he continued, stepping toward
+the spot where Green lay.
+</p>
+<p>
+The man bending over Green was about to
+reply when Nestor laid a hand on his arm. The
+boy had been awakened at the first shot and
+had slipped out of his tent and over to the side of
+the wounded man, being the first to arrive there.
+</p>
+<p>
+“Wait,” he said, as the ranger looked up
+in surprise. “Green is not seriously injured,”
+Ned went on, “but I want to make that rascal
+think he is.”
+</p>
+<p>
+“What’s the idea?” asked the other, glancing
+from face to face about him.
+</p>
+<p>
+“When he stands under a tree with a rope
+about his neck,” Ned said, “he’ll tell us the
+truth about this affair.”
+</p>
+<p>
+“He was trying to steal the machine,” the
+other said.
+</p>
+<p>
+“Green has a bullet hole through his shoulder,”
+Ned said, “but I want you to treat the
+<span class='pagenum pncolor'><a id='page_210'></a>210</span>
+prisoner as if the shot had been fatal. Kindly
+carry him to his tent.”
+</p>
+<p>
+The command was instantly obeyed, for the
+foresters all knew why Ned was there, and understood
+that he was the personal representative
+of the Secret Service chief at Washington. Ned
+then called Frank aside and spoke a few words
+in a whisper. The boy grinned and hastened
+back to the group about Sawyer.
+</p>
+<p>
+“Nestor wants to talk with Sawyer,” he explained,
+“and wants me to take him to his tent.”
+</p>
+<p>
+“We’ll take him to Nestor’s tent after we
+get done with him,” declared a burly forester
+whose face bore many evidences of the hard fight
+he had made during the fire. “It won’t take
+us long to settle with him.”
+</p>
+<p>
+Frank spoke a few words to the man and he
+was one of the first to push the prisoner toward
+Nestor’s tent.
+</p>
+<p>
+“If you’ll keep those men off me,” were
+Sawyer’s first words, “I’ll tell you what you
+want to know. They mean to kill me.”
+</p>
+<p>
+“I think there is little doubt about that,”
+was Ned’s reply. “Why did you want the
+aeroplane?”
+</p>
+<p>
+“If you must know,” was the reply, “I was
+sent here to get it, or to wreck it so you couldn’t
+use it.”
+<span class='pagenum pncolor'><a id='page_211'></a>211</span>
+</p>
+<p>
+This looked promising, and Ned waved a
+hand at Frank.
+</p>
+<p>
+“Throw him out here!” came a gruff voice
+from the crowd.
+</p>
+<p>
+“I won’t tell,” Sawyer went on, “unless you
+promise to keep them away from me. I didn’t
+mean to kill Green, and no court will convict
+me.”
+</p>
+<p>
+“When did you come here?” asked Ned.
+</p>
+<p>
+“A month ago,” was the reply. “The day
+you landed in San Francisco a man came to my
+boarding house and employed me.”
+</p>
+<p>
+“He mentioned the aeroplane?”
+</p>
+<p>
+“Yes, he knew all about it.”
+</p>
+<p>
+“Treachery in the Secret Service, eh?” asked
+Ned.
+</p>
+<p>
+“I don’t know how he gained his information,”
+was the reply. “He told me that he had
+secured a job for me in the forest service, and
+that I was to join the crew in this district.”
+</p>
+<p>
+“And steal the aeroplane?”
+</p>
+<p>
+“Steal it or wreck it. There are men with
+the other crews. You would have found an
+enemy wherever you landed.”
+</p>
+<p>
+This was all very amazing, and Ned wondered
+how many pitfalls had been set for him in
+San Francisco. He had no doubt that Sawyer
+<span class='pagenum pncolor'><a id='page_212'></a>212</span>
+was telling the truth. The question was as to
+whether he would tell the story as it was from
+that point on.
+</p>
+<p>
+“Who was it that engaged you—gave you
+your instructions?” he asked.
+</p>
+<p>
+“I don’t know,” was the reply.
+</p>
+<p>
+Ned swung his hand again, and a fierce demand
+that the prisoner should be thrown out
+arose from the group outside. Sawyer shivered
+and crept out of his camp-chair to Nestor’s side.
+His face was deadly pale, being sheltered from
+the ruddy glow of the fires. Just where the men
+stood outside lay a red lance of light, giving a
+demon-like look to their rugged faces.
+</p>
+<p>
+“If you don’t tell me the truth,” Ned said,
+“I can’t protect you.”
+</p>
+<p>
+“I tell you I don’t know,” wailed the frightened
+man. “I had never seen him before. I
+wanted a job and took what he offered. I
+didn’t think it would be so great a crime to steal
+or wreck an aeroplane.”
+</p>
+<p>
+“What were you to receive for the job?”
+</p>
+<p>
+“One thousand dollars.”
+</p>
+<p>
+“Hurry up! Throw that sneak out!”
+</p>
+<p>
+Sawyer, like the coward he was, threw himself
+down on the floor of the tent and groveled
+at Ned’s feet.
+<span class='pagenum pncolor'><a id='page_213'></a>213</span>
+</p>
+<p>
+“You would know the man again?” asked
+Ned.
+</p>
+<p>
+“Yes; I can pick him out of a score of men.”
+</p>
+<p>
+“You will do this willingly?”
+</p>
+<p>
+“Yes; I’m sick of the whole game. I didn’t
+mean to hurt Green. I wanted to scare him
+away so I could get back to my tent without
+being recognized. That is all I wanted, and I
+did not mean to hit him at all.”
+</p>
+<p>
+There was a great deal more talk between
+the two. Ned soon became convinced that
+Sawyer was a weak man, morally and intellectually,
+who would be apt to follow the lead of
+one stronger than himself.
+</p>
+<p>
+After Ned had left a guard over the man
+and visited Green—who was doing very well,
+and laughing over the trick the boy had played
+on Sawyer—he went back to his rough bed, well
+satisfied with the events of the night.
+</p>
+<p>
+“By the way,” Frank said, crawling into
+the tent after assisting in caring for the wounded
+man, “I don’t understand what you mean by
+saying that you’ve got a clue which you think
+will force the man behind the scenes out on the
+stage, in full view of the audience. If there is
+such a clue hovering about I haven’t become
+acquainted with it.”
+<span class='pagenum pncolor'><a id='page_214'></a>214</span>
+</p>
+<p>
+“The clue is hardly well enough advanced to
+talk about,” Ned replied.
+</p>
+<p>
+“But if you’ve got a line on the leader of this
+bunch you’ve won the case,” suggested Frank.
+</p>
+<p>
+“That is what the government sent me here
+for,” Ned replied. “The chief of the Secret
+Service expects me to round up the man responsible
+for the frequent forest fires. I think
+now that he should have told me that smuggling
+was going on up here, but he may have had a
+good reason for not doing so.”
+</p>
+<p>
+“You know what Mr. Green said,” Frank
+interrupted. “He said the government officers
+wanted you to take the case and find out everything
+for yourself. Perhaps they feared that
+you would pay too much attention to these
+smugglers, and let the forest fires issue go with
+scant investigation. They might have arrested
+the smugglers at any time, you know.”
+</p>
+<p>
+“Perhaps so,” Ned replied, “But that wouldn’t
+have brought the manager of the unlawful
+enterprises into the hands of the law. After
+all, the Secret Service men may have been right
+in sending me up here without instructions or
+special information. What a laugh they would
+have had if I had failed to discover the Chinamen
+and the opium.”
+<span class='pagenum pncolor'><a id='page_215'></a>215</span>
+</p>
+<p>
+“Perhaps they wanted to see if you would
+discover them,” laughed Frank. “Have you
+any idea,” he added, “that the Secret Service
+men knew that you would be followed in here—that
+the plans of the government regarding your
+work were known to the outlaws? Do you think
+they knew of the employment of Sawyer and the
+others by the men at the head of the conspiracy?”
+</p>
+<p>
+“No; I hardly think the man who gave me
+final orders at San Francisco knew that all he
+did was known to the men he was fighting,”
+Ned replied. “The head of the bunch put a
+good one over on him there.”
+</p>
+<p>
+“And came near putting one over on you,
+also,” grinned Frank. “The aeroplane has been
+attacked twice already, and others are doubtless
+waiting to get a crack at it.”
+</p>
+<p>
+“They will have to hurry up if they do,”
+Ned said, with a chuckle, “and you will have to
+look out for yourself if they succeed, for I’m
+going to have you take me to Missoula in the
+morning and then go back and collect the boys.”
+</p>
+<p>
+“And not come back here again?” asked
+Frank.
+</p>
+<p>
+“Not unless we come back for a pleasure
+trip,” was the reply.
+<span class='pagenum pncolor'><a id='page_216'></a>216</span>
+</p>
+<p>
+“Well,” Frank said, “that pleasure trip idea
+looks pretty good to me. Why not?”
+</p>
+<p>
+“I may have time,” Ned replied.
+</p>
+<p>
+Frank threw himself on the blankets which
+had been provided by Mr. Green and closed his
+eyes, which were still smarting from the effects
+of the smoke.
+</p>
+<p>
+“If you go away to-morrow,” he said, presently,
+“what is to become of the clues we found
+in the cavern by the lake?”
+</p>
+<p>
+“All provided for,” Ned answered.
+</p>
+<p>
+“And all the Chinks, and everything you
+discovered while visiting them in the caves almost
+under the divide?”
+</p>
+<p>
+“Everything provided for,” Ned said, sleepily.
+</p>
+<p>
+“And you think you can close this case by
+going to San Francisco?” demanded Frank, a
+touch of sarcasm in his tone.
+</p>
+<p>
+“Go to sleep, little boy,” said Ned, in a
+tantalizing tone.
+</p>
+<p>
+“But do you?” insisted the boy.
+</p>
+<p>
+“Of course I do,” was the muttered reply.
+“Go to sleep, little man!”
+</p>
+<p>
+And Frank tried to obey, but sleep would
+not come. The fire still smouldered over in the
+west. The ruddy light of the embers was still
+<span class='pagenum pncolor'><a id='page_217'></a>217</span>
+touching the camp with its red fingers. The
+smoke was still asserting itself in the air. The
+puzzle was still there!
+</p>
+<p>
+After the boy had rolled over at least fifty
+times, and arose to consult a water bag at least
+a dozen times, he seated himself under the flap
+of the tent and looked out. There was a moon
+now, and the smoke only half hid it. Far off
+in the woods wild creatures were expressing
+their opinion of the fire and the wanton destruction
+of their homes. There was a faint rustle
+in the foliage of the trees east of the “burn.”
+</p>
+<p>
+“Gee!” the boy muttered. “I’d like to
+come back here for a month!”
+</p>
+<p>
+Then his attention was attracted to the savage
+growl of some animal in the thicket beyond
+the fire limit of the “burn.” It seemed to the
+boy as if some man-eating creature had cornered
+a bit of animate supper, but couldn’t
+reach it. The language used by the forest resident
+seemed to be in the tongue of the panther.
+While he listened a cry which was not that of a
+hungry beast came out of the gloom.
+</p>
+<p>
+That was a cry for help, surely. Frank put
+his revolver and his searchlight into convenient
+pockets and set out for the scene of the disturbance,
+without awakening any of the sleepers.
+<span class='pagenum pncolor'><a id='page_218'></a>218</span>
+It was slow work pushing through the bushes,
+and the boy wondered if a fire there, well guarded
+on a quiet day, wouldn’t be a good thing.
+</p>
+<p>
+He kept his searchlight ahead and looked
+about for the source of the noises as he advanced
+in the darkness. In a short time he heard a
+voice he knew, but hardly expected to hear
+there.
+</p>
+<p>
+“Hurry up!” the voice said. “I’m goin’ to
+tumble out of this tree in about a minute! I’m
+that hungry! I thought you might meet me
+with a pie under one arm.”
+</p>
+<p>
+“Well, why don’t you come down, then?”
+Frank asked.
+</p>
+<p>
+“If you’ll turn your honorable attention to
+that tree to the east,” Jimmie said, “your excellency
+will observe a panther waiting for his
+supper. He’s been tracking me all day, getting
+bolder every minute. Now, if I turn this searchlight
+away for an instant, he’ll jump on me, and
+there you are. No more Jimmie McGraw than
+a rabbit!”
+</p>
+<p>
+“I didn’t see your light at first,” Frank said,
+“for it was hidden by the foliage of the trees.
+I suppose you want me to shoot the cat?”
+</p>
+<h2><span class='pagenum pncolor'><a id='page_219'></a>219</span><a name='chXVII' id='chXVII'></a>CHAPTER XVII.—THE TIME FOR THE ROUND-UP.</h2>
+<p>
+“Sure,” Jimmie answered. “Shoot the cat!”
+</p>
+<p>
+“Well, keep your light on him, and wait
+until I can get where I can see him. The cat
+frequently resents being wounded.”
+</p>
+<p>
+“Cripes!” cried Jimmie. “Don’t shoot unless
+you kill him, for he’ll jump at me then for
+sure. He’s angry now—hear him pound with
+his tail? I fired all my loads at him an’ he
+dodged the bullets.”
+</p>
+<p>
+“You couldn’t shoot craps!” scorned Frank.
+</p>
+<p>
+The panther, a great brute made ferocious
+by the excitement of the fire, and probably
+scorched a little, could now be heard moving
+in the branches of a tree not far from that
+in which Jimmie was perched. In a moment
+Frank reached a point from which the beast’s
+face could be seen.
+</p>
+<p>
+He thought to himself that it looked like a
+tiger head fastened against a gray cloud with
+unseen pins. Jimmie’s searchlight brought the
+evil face, the cruel eyes, the back-sloping ears,
+<span class='pagenum pncolor'><a id='page_220'></a>220</span>
+the faintly-moving jaws, out into strong relief,
+as the circle of flame was only large enough to
+cover the face.
+</p>
+<p>
+The beast heard Frank moving in the bushes
+below and turned its head to look, at the same
+time crouching low, as if to spring.
+</p>
+<p>
+The first bullet struck him fair in the throat,
+the second entered the head just above the eyes,
+the third, coming so rapidly on the others that
+the three reports seemed to merge into one,
+entered the body over the heart. The great
+beast was dead when the body struck the ground.
+</p>
+<p>
+Jimmie was not long in getting down to
+Frank’s side and grasping him by the shoulders
+in a hug which threatened to end in a scuffle.
+</p>
+<p>
+“Get away!” Frank said. “Suppose there’s
+another cat here? If there is he’ll get one of us
+through your foolishness.”
+</p>
+<p>
+“There were two,” Jimmie said, coolly, “but
+I killed one.”
+</p>
+<p>
+“How did you get here?” was the next question,
+asked as the boys turned toward the camp.
+</p>
+<p>
+“How do you think I got here?” returned
+Jimmie.
+</p>
+<p>
+“Walked!” laughed Frank.
+</p>
+<p>
+“Yes, I walked.”
+</p>
+<p>
+Jimmie stopped and rubbed his legs with
+careful hands.
+<span class='pagenum pncolor'><a id='page_221'></a>221</span>
+</p>
+<p>
+“I’m all wore out!” he said. “I can’t walk
+any farther to-night.”
+</p>
+<p>
+“All right,” Frank said, with a grin. “I’ll
+leave you both lights to keep the cats off with,
+and my gun, and come out after you in the
+morning after breakfast.”
+</p>
+<p>
+“Oh, my eats!” Jimmie cried. “Lead me
+to something that will sustain life! I’m starving,
+I tell you.”
+</p>
+<p>
+“You walked all the way?” asked Frank.
+</p>
+<p>
+“Sure! Forty miles at least.”
+</p>
+<p>
+“Where are the others?”
+</p>
+<p>
+“Pat, Jack and the Chink Scout? Pat came
+up just before I started, riding on a burro, an’
+in the custody of a small party of rangers, who
+thought he had been setting fires. The rangers
+went into camp over there, all tired out, an’
+Jack an’ Pat settled down with them. I run
+away.”
+</p>
+<p>
+“They don’t know where you are?” asked
+Frank.
+</p>
+<p>
+“Nix know!” replied the boy.
+</p>
+<p>
+“But how did you ever get through the burning
+forest?” asked Frank, hardly believing the
+boy’s story of his long walk.
+</p>
+<p>
+“This ‘burn’ is only a mile wide,” Jimmie
+said. “I walked on the south edge of it. Say,
+<span class='pagenum pncolor'><a id='page_222'></a>222</span>
+there are plenty of lives lost! Bears, an’ cats,
+an’ all that. I guess this will be an agreeable
+place to live in about a week—not!”
+</p>
+<p>
+The boy was indeed “all in,” as he expressed
+it. He had walked since early morning through
+a tangled forest black with smoke, through an
+atmosphere burned and smoked out of its life-giving
+qualities. And all this exertion in order
+that he might be near his chum, Nestor.
+</p>
+<p>
+Fortune had favored the lad, and he had at
+last blundered on the camp where Ned had taken
+refuge, otherwise he might have died in the forest
+from hunger and exhaustion, or been devoured
+by some of the savage beasts which had
+followed him all day.
+</p>
+<p>
+“Where’s Ned?” Jimmie asked, as they stood
+before the little row of tents.
+</p>
+<p>
+“Asleep,” was the reply, “and you let him
+alone for to-night. He’s been having a lively
+time. But how in the name of all that’s wonderful
+did you ever find your way here?” the
+boy added.
+</p>
+<p>
+“I don’t know,” was the reply. “I knew
+that Ned would be wherever the fire was, and
+so started east. Not so very long ago I heard
+a couple of shots, and that directed me toward
+the camp. Who was hurt?”
+<span class='pagenum pncolor'><a id='page_223'></a>223</span>
+</p>
+<p>
+Frank explained, briefly, what had taken
+place, hunted up a liberal meal for the boy, and
+then saw him settled for the night.
+</p>
+<p>
+Ned’s astonishment at seeing the boy in the
+morning may well be imagined.
+</p>
+<p>
+“Huh!” Jimmie said. “You thought you
+would fool me out of all the fun!”
+</p>
+<p>
+Ned laughed and asked about the others,
+finally informing Jimmie that he was leaving
+that morning for San Francisco by the aeroplane
+route.
+</p>
+<p>
+“Then I’m goin’!” declared the boy. “I’m
+not goin’ to be chucked into the discard again.”
+</p>
+<p>
+“You’ll have to sit in Frank’s lap,” grinned
+Ned, “and the machine may tip over with such
+a load, at that.”
+</p>
+<p>
+“I guess it didn’t tip over when Frank and
+Jack an’ yours truly run it,” Jimmie replied.
+“Anyway, I’m goin’ with you.”
+</p>
+<p>
+Before leaving for Missoula, where he was
+to surrender the aeroplane to Frank, Ned had
+another long talk with Mr. Green, whose wound
+was not so serious as it had been considered the
+night before. The forester told him what he
+knew of the men under the leadership of Greer,
+saying that he might have arrested Greer at any
+time during the month, and, what is more, convicted
+<span class='pagenum pncolor'><a id='page_224'></a>224</span>
+him of smuggling both Chinamen and
+opium over the border.
+</p>
+<p>
+“But what good would it have done?” Green
+went on. “The conspirators in Washington,
+or New York, or San Francisco would have
+chosen another leader, and the game would have
+gone on as before.”
+</p>
+<p>
+“That is very true,” Ned admitted, “and
+still, it seems to me that the time to round the
+fellows up has come!”
+</p>
+<p>
+“Do you give that as an order?” asked the
+other, a flash of excitement showing in his face.
+</p>
+<p>
+“Yes,” was the reply.
+</p>
+<p>
+“But some of them have gone to Portland
+with the Chinks—some to Frisco, I think. What
+about that?”
+</p>
+<p>
+“If you can spare men,” Ned said, “follow
+them.”
+</p>
+<p>
+“You’re on!” laughed Green. “I’ve been
+waiting for some such orders for a long time.
+You’re on!”
+</p>
+<p>
+“And follow on to Frisco as soon as you can,”
+Ned continued. “Address me, or look for me,
+if you are able to be about after you get there,
+at the Federal building.”
+</p>
+<p>
+“I’ll be there in a week,” Green said, his
+eyes showing the joy of the coming fight with
+<span class='pagenum pncolor'><a id='page_225'></a>225</span>
+the outlaws, “and I’ll have a bunch of prisoners
+with me.”
+</p>
+<p>
+The forester hesitated a moment, as the importance
+of the proposed move came to him,
+then faced Ned with a hesitating look. It was
+plain to the boy that Green wanted to ask a
+question which he believed to be either personal
+or impertinent.
+</p>
+<p>
+“Is there something else?” Ned asked.
+</p>
+<p>
+Green still hesitated, his eyes on the ground.
+</p>
+<p>
+“Are you sure of your clues?” he asked, then.
+</p>
+<p>
+“I think so,” was the reply.
+</p>
+<p>
+“Because, you see,” Green went on, “the
+government doesn’t want any trap sprung until
+the whole bilin’ is within reaching distance.
+After the good work you have done here, I
+wouldn’t like to have you order the round-up
+and then find that the men you wanted were
+still out on the range.”
+</p>
+<p>
+“Thank you for your frankness,” Ned replied.
+</p>
+<p>
+“I just want to be sure that you are sure,”
+smiled Green. “It would mix things for me to
+make these arrests and have the big ones get
+away, now, wouldn’t it?”
+</p>
+<p>
+“Indeed it would,” Ned admitted, “but I
+think it is safe to go ahead as we planned a moment
+ago.”
+<span class='pagenum pncolor'><a id='page_226'></a>226</span>
+</p>
+<p>
+“All right!” Green said, but there was still
+doubt in his eyes.
+</p>
+<p>
+“And I’ll accept all the responsibility,” Ned
+added.
+</p>
+<p>
+“I have a suggestion to make,” Green said,
+then. “Why not go on to Frisco in the aeroplane
+and ask for instructions? You can make
+the trip in the airship in no time, but it is a long
+ride by rail.”
+</p>
+<p>
+“I think,” Ned replied, with a laugh, “that
+the game will be ripe just about the time I get
+to Frisco by rail. Besides, I don’t want the
+outlaws to know that I’m going to the city.
+They would know it if they saw the aeroplane
+making for the coast. Well, if I leave Frank
+navigating it in this district they will think I
+am still here. Don’t you see?”
+</p>
+<p>
+“Go it!” laughed Green. “I reckon you
+know what you’re about.”
+</p>
+<p>
+“Anyway,” Ned said, “I’ve got to play the
+game in my own way if I play it at all.”
+</p>
+<p>
+“I see,” observed Green, and the two parted.
+</p>
+<p>
+The aeroplane had not been damaged at all
+by the fire, but Ned went over it carefully before
+attempting a start. Sawyer, trembling with
+fright, was brought out to show where he had
+meddled with the machinery.
+<span class='pagenum pncolor'><a id='page_227'></a>227</span>
+</p>
+<p>
+“I didn’t harm it any,” the prisoner said.
+</p>
+<p>
+“There are some burrs missing,” Ned said.
+</p>
+<p>
+Sawyer brought half a dozen out of a pocket
+and passed them to Ned with a reluctant hand.
+</p>
+<p>
+“I neglected to tell you that I had them in
+my pocket,” he said.
+</p>
+<p>
+“What did Green say to you this morning?”
+asked Ned, screwing the burrs on where they
+were needed.
+</p>
+<p>
+“He says he won’t be hard on me, if I tell
+all I know about the men who are doing these
+tricks,” was the reply.
+</p>
+<p>
+“You told me all you know?” asked Ned.
+</p>
+<p>
+“Yes, there is nothing else to tell. I’m so
+glad to think that Green is not going to die from
+the wound I gave him that I’ll do everything in
+my power to bring the men who put me up to
+this to punishment.”
+</p>
+<p>
+“Sure you can identify the man who hired
+you?”
+</p>
+<p>
+“Dead certain,” was the reply.
+</p>
+<p>
+“Then I’ll have one of the men bring you to
+Frisco,” Ned said. “You will be wanted there.”
+</p>
+<p>
+“All right; anything the government wants
+goes!”
+</p>
+<p>
+In half an hour the three boys, Ned, Frank
+and Jimmie, were on the aeroplane, sailing
+<span class='pagenum pncolor'><a id='page_228'></a>228</span>
+through the clear air of a splendid summer
+morning. Below they could see the long, narrow
+strip of land which had been swept by the
+fires. Off to the north was the British frontier,
+with Lake Kintla glimmering in the sunshine.
+</p>
+<p>
+“Aren’t we going back to that lake cavern
+again?” asked Frank.
+</p>
+<p>
+“Not just now,” Ned replied.
+</p>
+<p>
+“I didn’t know that you got all you wanted
+in there,” Frank went on. “I had an idea that
+you were trying to identify the man we found
+dead there.”
+</p>
+<p>
+“I think I learned all there was to learn
+there,” Ned replied.
+</p>
+<p>
+“He spent a lot of time in there before he
+went to Frisco,” Jimmie said. “He made me
+go in there with him, and I didn’t like it.”
+</p>
+<p>
+“And so no one will ever know who the dead
+man was?” asked Frank.
+</p>
+<p>
+“I have been given a name,” Ned said, “a
+name to call him by, but I don’t exactly like to
+accept the information, considering the source
+from which it came.”
+</p>
+<p>
+The aeroplane drifted to the west and north
+easily under the steady pulse of the motors, and
+the plateau where Jimmie had left the boys and
+the foresters was soon in sight.
+<span class='pagenum pncolor'><a id='page_229'></a>229</span>
+</p>
+<p>
+“I wonder if they’re all alive?” said Jimmie.
+</p>
+<p>
+“What could happen to them?” demanded
+Frank.
+</p>
+<p>
+“Oh,” Jimmie replied, with biting sarcasm,
+“there is nothing here to harm ’em! This is a
+pink tea, this is! This is a church fair, where
+you get ices made out of the cream they skim
+off the cistern!”
+</p>
+<p>
+“You’re getting nutty!” Frank said, with a
+grin.
+</p>
+<p>
+“When I left ’em,” Jimmie went on, “the
+boys an’ the foresters were wondering if the outlaws
+would come back an’ kill ’em one by one
+or just blow up the caves underneath the plateau
+an’ send ’em up in the air without any good
+means of gettin’ down.”
+</p>
+<p>
+“Then we’ll look them up,” Ned said.
+</p>
+<p>
+The great divide lay down below, and the
+plateau was in plain sight, with the early sunshine
+streaming over it. When the aeroplane
+circled about it a shout came up to Ned’s ears,
+then a shot, and the powder smoke drifted lazily
+upward in the clear air.
+</p>
+<p>
+“Somethin’ doin’!” Jimmie cried. “Suppose
+we go down an’ see.”

+<p>
+It was very still in the bachelor apartment,
+and, as on the occasion of his previous visit,
+Nestor saw, as he slipped through the doorway
+leading from the private hall, that the lights
+were burning low.
+</p>
+<p>
+On this night there was no opium-drugged
+victim lying on the couch. There was a movement
+in the room beyond, and Ned could hear
+the soft tread of slippered feet and occasionally
+the rattle of dishes. It was evident that midnight
+luncheon was being prepared, and that
+the master of the habitation would soon be on
+hand.
+</p>
+<p>
+Closing the door softly—the same having
+been opened with a skeleton key—Ned stepped
+across the room to the writing desk which he
+had examined on that other night. After
+searching the half-open drawer for an instant,
+he took out a number of papers and examined
+them. He also took a check-book out and put
+it into a pocket. The papers he returned to
+<span class='pagenum pncolor'><a id='page_231'></a>231</span>
+the desk. The check-book was an old one,
+there being few blank checks in the binding, but
+plenty of stubs.
+</p>
+<p>
+Then Ned looked at the lock of the desk.
+It had been out of repair at his previous visit,
+but was in excellent shape now. He removed
+the new key and inserted the one with the broken
+stem which had so excited the interest of Albert
+Lemon and Jap on occasion of his previous visit.
+</p>
+<p>
+The key with the broken stem did not fit.
+A new lock had been put on. Next Ned went
+to a mantel over a gas grate and lifted the cover
+from a little ivory box which stood there. At
+the very bottom of the box, under buttons, pins,
+needles, and odds and ends, he found a key.
+This one was whole, and it was an exact duplicate
+of the one with the broken stem.
+</p>
+<p>
+Ned had been in San Francisco three days,
+and Jimmie was not far away. On bringing the
+aeroplane to the plateau on the day of his return
+to Missoula he had found Ernest Whipple,
+Jack, Pat, Liu, and a small party of rangers
+anxiously awaiting him. Also “several tough
+ones waitin’ for an introduction,” as Jimmie
+put it. It seems that the fake foresters had returned
+to the cave after the fire in the caÃąon had
+burned itself out and had at once discovered
+<span class='pagenum pncolor'><a id='page_232'></a>232</span>
+that the prisoner had vanished, also that Liu,
+the Chinese boy, had disappeared with him.
+</p>
+<p>
+There had been a long search for the missing
+boys, as the outlaws knew very well that the
+escape meant the bringing of officers to the caves,
+but they had not been discovered until a short
+time before the arrival of the aeroplane.
+</p>
+<p>
+When Ned reached the plateau—in fact, before
+he reached it—he heard the whistling of
+bullets aimed at the big bird. The outlaws
+were trying to cripple the aeroplane and so give
+the riders a tumble. The boys landed in safety,
+however, and joined the others.
+</p>
+<p>
+Seeing the boys thus reinforced, the outlaws
+had withdrawn, and the rangers had conducted
+them to a pass which led over the divide. So
+it was that Ned had left them, making their way
+down toward the Valley of the Wild Animals,
+where a large number of rangers were encamped,
+and where Frank was to come for them with the
+aeroplane as soon as Ned landed at Missoula.
+</p>
+<p>
+There were numerous shots fired at the aeroplane
+as it mounted into the sky again, but no
+harm was done.
+</p>
+<p>
+“If they had been shootin’ at that cat last
+night,” Jimmie said, in derision, “they would
+’a’ been eaten alive.”
+<span class='pagenum pncolor'><a id='page_233'></a>233</span>
+</p>
+<p>
+“They are nervous,” Frank said, “and don’t
+dare come out of their hiding places so as to get
+a good sight at us. They are afraid of the
+rangers, and afraid that we’ll drop a bomb or
+something of that sort down on them.”
+</p>
+<p>
+This explanation of the bad marksmanship,
+as well as the failure of the outlaws to rush the
+aeroplane, was accepted by the boys, who had
+anticipated a fight with the fellows. It was
+afterwards learned, too, that there were only
+half a dozen outlaws in the group, and that they
+had been sent back to guard the caves and not
+to fight rangers unless they were attacked.
+</p>
+<p>
+Ned had been very busy since his return to
+the city, having made many inquiries concerning
+Albert Lemon and his servant, the Japanese
+attendant who had given the boy such a chilly
+reception on the night of the first visit.
+</p>
+<p>
+Lemon, he had been informed, was a millionaire
+of eccentric habits. According to Ned’s
+source of information, he would absent himself
+from his usual haunts for days at a time, and
+would then return to shut himself up in his
+rooms, at home to no one, and attended only by
+Jap.
+</p>
+<p>
+After a time the clatter of dishes grew louder
+in the adjoining room, giving notice, doubtless,
+<span class='pagenum pncolor'><a id='page_234'></a>234</span>
+that the luncheon being prepared was nearly
+ready to serve. Then the boy seated himself
+behind a screen which cut off a corner of the
+room and waited. He had occupied his retreat
+only a short time when a key turned in the door
+and the man he had talked with on his first visit
+entered.
+</p>
+<p>
+It was not the old, half-dazed, disreputable
+Lemon who stepped into the room, but a young
+man handsomely dressed and evidently very
+wide awake and in the best of spirits. After
+seeing that the window shades were closely
+drawn he turned on the lights and dropped into
+a chair at the writing desk.
+</p>
+<p>
+Ned saw him rummage the pigeon-holes for
+a moment, extract a folded paper, and fall to
+checking off the items. The boy had examined
+this sheet while at the desk, and so knew
+what it contained. After checking the items
+the man drew out a long pocket-book and placed
+its contents on the writing board.
+</p>
+<p>
+The boy gave a quick start when he saw
+what the book had contained, for a large package
+of yellow-back bank notes lay exposed to
+view. The man counted them carefully, compared
+the total with the figures he had marked
+<span class='pagenum pncolor'><a id='page_235'></a>235</span>
+on the sheet, and then sat back in his chair with
+a satisfied smile on his face.
+</p>
+<p>
+“Everything correct!” he said.
+</p>
+<p>
+Then he lighted a cigar and turned to the
+door opening into the inner room.
+</p>
+<p>
+“Jap!” he called softly. “Oh, Jap!”
+</p>
+<p>
+The door opened and the servant looked in.
+</p>
+<p>
+“Come here!” Lemon commanded. “What
+have you been doing?” he added, as the Jap
+stood before him.
+</p>
+<p>
+“Nothing,” was the reply.
+</p>
+<p>
+“You are not telling the truth,” Lemon said.
+“You have been seen about the city, in tea
+houses, talking with strangers.”
+</p>
+<p>
+“I have not been out of the rooms,” the
+other insisted, stubbornly.
+</p>
+<p>
+“Let it pass,” Lemon said, in a moment.
+“There may be some mistake. Any one been
+here?”
+</p>
+<p>
+“No one.”
+</p>
+<p>
+The servant appeared to have a perfect
+knowledge of English. He looked into his master’s
+face with a bland smile, but now and then
+his eyes sought the screen behind which Ned
+was hidden.
+</p>
+<p>
+“Well, some of the boys will be up here to-night,” Lemon
+<span class='pagenum pncolor'><a id='page_236'></a>236</span>
+said. “See that there is plenty
+to eat. Go, now.”
+</p>
+<p>
+The servant turned to the door opening into
+the private hall, stood with his hand on the knob
+for an instant, and then, apparently changing
+his mind, went out through the doorway by
+which he had entered. If Lemon had been listening
+intently he would have heard a quick
+movement in the back room as Jap closed the
+door.
+</p>
+<p>
+In a moment there was another movement in
+the private hall, and then Ned heard the corridor
+door open. He pushed the screen aside and
+stepped out before the astonished occupant of
+the rooms.
+</p>
+<p>
+“What does this mean?” Lemon demanded,
+a quiver of excitement—or it might have been
+consternation—in his voice.
+</p>
+<p>
+While he spoke he moved toward a table
+where a revolver lay in full view.
+</p>
+<p>
+“Never mind that,” Ned said, coolly. “We
+can arbitrate our differences without its assistance.
+Besides, it is not loaded.”
+</p>
+<p>
+“What are you doing here?” Lemon almost
+shouted, his face growing white, either with rage
+or fear. “Leave the room immediately.”
+<span class='pagenum pncolor'><a id='page_237'></a>237</span>
+</p>
+<p>
+Ned dropped into a chair and motioned toward
+another.
+</p>
+<p>
+“Sit down!” he ordered.
+</p>
+<p>
+“Your impudence is amazing,” Lemon said,
+but he took the chair.
+</p>
+<p>
+In a moment, however, he turned to the door.
+</p>
+<p>
+“Jap!” he called.
+</p>
+<p>
+Again the door opened and the servant looked
+in.
+</p>
+<p>
+“Are you armed?” Lemon asked.
+</p>
+<p>
+The servant nodded, fixing a pair of inscrutable
+eyes on Ned’s face as he did so.
+</p>
+<p>
+“Very well,” was the reply. “Stand there
+by the door. How did this man gain entrance
+here?”
+</p>
+<p>
+The only reply was a shrug of the shoulders.
+</p>
+<p>
+“Let it pass for the present,” Lemon said,
+with a smile of triumph. “Stand there and
+shoot when I give the word.”
+</p>
+<p>
+The servant nodded again. Ned remained
+seated, his eyes fixed coolly on the face of the
+master.
+</p>
+<p>
+“Now, what do you want?” demanded
+Lemon. “You don’t look exactly like a common
+sneak thief.”
+</p>
+<p>
+“You doubtless remember,” Ned began, in
+a level voice, “that I did myself the honor of
+<span class='pagenum pncolor'><a id='page_238'></a>238</span>
+calling at these rooms not long ago in quest of
+information of one—of one Felix Emory?”
+</p>
+<p>
+Lemon started at the name, but gained confidence
+as he glanced toward the servant at the
+door.
+</p>
+<p>
+“Yes, I remember,” he said. “What about
+it?”
+</p>
+<p>
+There was a sharp ring at the corridor door
+before Ned spoke again. The Jap looked inquiringly
+at his master.
+</p>
+<p>
+“Company may prove of value just now,”
+Lemon said. “Will you see who is there?”
+</p>
+<p>
+It was clear to Ned that Lemon expected
+some of the associates he had mentioned as
+“the boys” when giving instructions about the
+luncheon, and there was a smile of welcome on
+his face when a bustle in the hall told of an
+arrival.
+</p>
+<p>
+There was only one man, however, and
+Lemon at first seemed disappointed, but in a
+moment he had his face under perfect control
+again.
+</p>
+<p>
+“Father!” he cried, springing to his feet.
+“It is good to see you here!”
+</p>
+<p>
+The newcomer, a man of perhaps sixty,
+well dressed and with the air of a man to whom
+marked attention was due, stood looking into
+<span class='pagenum pncolor'><a id='page_239'></a>239</span>
+Lemon’s face for an instant and then grasped
+his hand.
+</p>
+<p>
+“You have changed little, my son,” he said.
+</p>
+<p>
+Lemon smiled and indicated Ned with a
+slight motion of the hand.
+</p>
+<p>
+“Permit me to present to you my father,
+Mr. Leon Lemon,” he said, “and this, father,
+is a boy burglar who broke into my rooms in
+quest of plunder a short time ago,” he added.
+“We were having quite a cheerful talk when you
+came. I don’t know his name, unfortunately.”
+</p>
+<p>
+The old gentleman gave a start and attempted
+to rise from his chair.
+</p>
+<p>
+“Don’t distress yourself,” Lemon said. “He
+is quite harmless. Besides, Jap has him covered
+with the cannon he delights to carry.”
+</p>
+<p>
+“This is a strange situation,” the other said,
+wiping the sweat of excitement from his face.
+</p>
+<p>
+“One of the incidents which add to the joy
+of life,” Lemon said. “You remember Felix
+Emory?” he added. “Well, his pretense for
+this call is that he came to ask about him. Go
+ahead, Mr. Burglar.”
+</p>
+<p>
+“Perhaps you will also remember,” Ned
+went on, “that on my former visit here I exhibited
+a key with a broken stem—the key to
+that writing desk?”
+<span class='pagenum pncolor'><a id='page_240'></a>240</span>
+</p>
+<p>
+Lemon’s face hardened and he glanced furtively
+at the servant, but said not a word.
+</p>
+<p>
+“This key,” Ned said, producing the one
+mentioned, “was found in the pocket of the man
+who was found dead in the Rocky Mountains.
+You think you left it in the suit of clothes you
+gave Emory?”
+</p>
+<p>
+“Possibly,” was the strained reply. “But
+we have had enough of this,” Lemon added.
+“Call the police, Jap.”
+</p>
+<p>
+“Just a moment,” Ned went on, when the
+Jap moved toward the door. “When you could
+not find the key, Mr. Lemon, why didn’t you
+use the duplicate. The duplicate you kept in
+the box on the shelf? Why did you think it
+necessary to break the lock?”
+</p>
+<p>
+“The servant did that,” was the angry
+reply.
+</p>
+<p>
+“I see,” Ned replied, coolly, “perhaps that
+was done while you were up in the mountains
+with Emory—before he was killed?”
+</p>
+<p>
+“Possibly,” Lemon gritted out.
+</p>
+<p>
+“Now, since talking with you,” Ned continued,
+“I have been up in the mountains.
+There I found a man using a typewriter. By
+the way, have you a machine here?”
+</p>
+<p>
+“Certainly not,” was the angry reply.
+<span class='pagenum pncolor'><a id='page_241'></a>241</span>
+</p>
+<p>
+“But you formerly used one here?”
+</p>
+<p>
+“Never!” was the reply.
+</p>
+<p>
+“That is strange,” Ned said, “for when I
+came in here not long ago I took the liberty of
+looking through some papers in your desk, for
+which I ask your pardon. Well, I discovered
+that the machine you used here carried a defective
+letter ‘c.’ It looked in the writing like an
+‘o.’ The machine the man was using under
+the divide had the same defect. If you will
+observe the sheet you were examining a few
+moments ago, you will note the imperfect letter.”
+</p>
+<p>
+Lemon’s teeth clinked together sharply, but
+he did not speak.
+</p>
+<p>
+“When I came here last,” Ned continued,
+“you lay in an opium stupor on that couch.
+You had recently returned from a trip to Lake
+Kintla, where Emory was found dead. While
+in that section you visited a cavern on the eastern
+slope of the divide. There is where you
+used the typewriter taken from these rooms.”
+</p>
+<p>
+“My son never learned the keyboard,” said
+the old gentleman, an angry snap in his eyes.
+“He has never found it necessary to earn
+money.”
+</p>
+<p>
+Lemon turned to the old man and bowed,
+gratefully.
+<span class='pagenum pncolor'><a id='page_242'></a>242</span>
+</p>
+<p>
+“When you lay on the couch that night,”
+Ned continued, “there was the smear of the
+typewriter on the middle finger of your left hand,
+close to the nail. I use a double keyboard
+machine myself, and sometimes smut my finger
+on the ribbon when I turn the platen. Some
+papers I chanced upon in the mountains bear
+the mark of a smudged hand. You are careless
+in using the machine. You even left a blue
+record ribbon in the cave headquarters where
+the dead man was found. That was my first
+valuable clue!”
+</p>
+<p>
+“What papers did you steal while in the
+mountains?” demanded Lemon, springing to
+his feet, his face deadly white, his fists swinging
+aimlessly in the air.
+</p>
+<p>
+“Lists,” Ned replied. “Lists of Chinamen
+brought from over the border, and lists of opium
+cases smuggled in. I have the papers in my
+possession now. They match with the statement
+you examined just before I made my appearance
+in the room—just before you counted
+the money you received from this illegal traffic.”
+</p>
+<p>
+The old man leaped at Ned, but the boy
+moved away and stood by the door. The Jap
+stepped closer. There came a sound of whispering, a
+<span class='pagenum pncolor'><a id='page_243'></a>243</span>
+noise of footsteps, from the hall outside.
+Then the door was opened and Greer,
+Slocum, Chang Chee and two others entered,
+glancing keenly at Ned as they passed him,
+still standing by the door.
+</p>
+<p>
+“Do you mean to accuse my son of crime?”
+shouted the old man, not noticing the new-comers
+in his rage and excitement. “You
+scoundrel!”
+</p>
+<p>
+“How do you know,” Ned asked, with a
+smile at the others, “that this man is Albert
+Lemon, your son?”
+</p>
+<h2><span class='pagenum pncolor'><a id='page_244'></a>244</span><a name='chXIX' id='chXIX'></a>CHAPTER XIX.—THE MAN BEHIND THE SCENES.</h2>
+<p>
+“Not my son!” shouted the old man. “This
+has gone quite far enough! Jap, call the police,
+and order this mad youngster taken away.”
+</p>
+<p>
+The younger man broke into a harsh laugh
+and turned to those who had just entered. Slocum
+and Chang Chee were whispering together,
+and a dangerous looking knife showed in the
+hand of the false ranger.
+</p>
+<p>
+“You hear what father says, boys,” Lemon
+said. “Remember that.”
+</p>
+<p>
+“What is this kid doing here, anyway?”
+demanded Slocum.
+</p>
+<p>
+“He came here, evidently, for the purpose
+of blackmailing me,” Lemon said. “He has
+papers stolen from the mountains—lists, he
+says they are—and they should be taken from
+him by force.”
+</p>
+<p>
+Slocum and Chang Chee started toward the
+boy, but he waved them back with his hand.
+</p>
+<p>
+“I will lay the papers on the table,” he said.
+“You are quite welcome to them for the present.”
+<span class='pagenum pncolor'><a id='page_245'></a>245</span>
+</p>
+<p>
+“I’ll take him down to the police station,”
+said Chang. “He ought not to be at large.
+Come, youngster.”
+</p>
+<p>
+“You seem to be able to talk pretty good
+English now,” laughed Ned. “Much better
+than the slang you gave out in the mountains.”
+</p>
+<p>
+“Come!” shouted the Chinaman. “You
+are here alone, so there is no need of a fight.
+Come along!”
+</p>
+<p>
+“We’ll see about my being here alone presently,”
+Ned said. “Anyhow, I’d better be
+here alone than with any one of you in the dark
+streets. I should be murdered before a block
+was passed. That is what you came to Frisco
+for, to murder me—just as the man in the lake
+cavern was murdered.”
+</p>
+<p>
+Those in the room looked at each other and
+remained silent. There was a tense moment,
+when every person there seemed gathering for a
+spring, when the lust of blood seemed in every
+glaring eye, but it passed.
+</p>
+<p>
+“Where are the Chinamen you brought away
+from the British border?” asked Ned of Chang
+Chee. “Are they in this city? Oh,” he continued,
+as Chang glared at him, “we knew that
+you were about to bring in a batch. You usually
+light forest fires in order to attract the attention
+<span class='pagenum pncolor'><a id='page_246'></a>246</span>
+of the rangers when you get ready to unload a
+band of Chinese on Uncle Sam. That is Doyers
+street cunning, Chang!”
+</p>
+<p>
+“You see,” he went on, “we have had the
+good luck to discover why the forests in Northern
+Idaho and Montana have been set on fire
+so frequently. I don’t care to say what I think
+of the wisdom of your course in so attempting
+to hide your movements, except that it attracted
+attention instead of diverting it. You
+firebugs might have been arrested long ago,”
+he continued, turning to Slocum, “but it was
+thought best to wait until the head center of
+the whole conspiracy was in the hands of the
+law. Now that this has been accomplished, I
+may speak.”
+</p>
+<p>
+The people standing around the boy looked
+into each other’s faces, and there was a movement
+as if to draw weapons.
+</p>
+<p>
+“Permit me to congratulate you on the
+discovery of the leader of the outlaws,” the old
+man said with a snarl. “Perhaps you will be
+kind enough to give us his name?”
+</p>
+<p>
+“There are no objections that I know of,”
+was the reply. “His name is Felix Emory.
+You may have heard of him.”
+<span class='pagenum pncolor'><a id='page_247'></a>247</span>
+</p>
+<p>
+“An old acquaintance of my son Albert,”
+the old man said.
+</p>
+<p>
+“That is the name of the man who was so
+mysteriously murdered in the Kintla lake
+cave,” Slocum observed. “Why do you place
+the crime on the dead?”
+</p>
+<p>
+“Felix Emory,” Ned said, “is not dead.
+He is alive at this moment—alive and in this
+room!”
+</p>
+<p>
+The young man broke into a jarring laugh
+and turned to the old man.
+</p>
+<p>
+“You remember the strange resemblance between
+Felix and myself,” he said. “Well, it
+seems to have deceived this clever young man.
+By the way, Slocum, why don’t you take the
+lad to the police station? We have no more
+time for him here.”
+</p>
+<p>
+Slocum and another sprang forward, but Ned
+opened the door with a quick motion and stood
+beyond their reach.
+</p>
+<p>
+“The man found dead in the cave,” the boy
+said, facing the old man, “had met with an accident
+in his youth. The first joint of the little
+finger of the right hand was missing. Also,
+there was a scar over his left eye—a trifling scar,
+made with a knife in the hands of a playmate.
+<span class='pagenum pncolor'><a id='page_248'></a>248</span>
+Do you recall these marks of identification, Mr.
+Lemon?” he added.
+</p>
+<p>
+The old man threw his hands to his face and
+stood silent for a moment while the others looked
+on in perplexed silence. When he uncovered
+his face again he stepped forward to the man he
+had called his son on entering the room.
+</p>
+<p>
+“Let me see your hands, Albert,” he said,
+kindly. “Bend down so I can see the scar on
+your forehead!”
+</p>
+<p>
+“Step aside, you old fool!” the young man
+cried, pushing the old man back rudely. “We
+have had enough of this, boys,” he continued,
+turning to the others. “The game is up unless
+we get rid of this dotard and this boy. Why
+don’t you get busy?”
+</p>
+<p>
+The old man dropped into a chair and lifted
+his face to Ned’s.
+</p>
+<p>
+“You found my son murdered?” he asked.
+“Then this man Felix Emory stands in his
+shoes! Even I was deceived by him! Why, he
+has been calling upon me for large sums of money
+during the past month. He has taken possession
+of my boy’s rooms. Was it this man Emory
+who killed him?”
+</p>
+<p>
+“We believe so,” was the reply. “The
+proof is within reaching distance.”
+<span class='pagenum pncolor'><a id='page_249'></a>249</span>
+</p>
+<p>
+“Out with them both!” shouted Emory.
+</p>
+<p>
+“Your son Albert took this man in and tried
+to do something for him,” Ned went on, “and
+was robbed and murdered for his pains. This
+man Emory was the leader of this choice band
+of smugglers and firebugs when he came to your
+son. The band was on the point of scattering
+because the officers were close on their track.
+They needed a man well up in the world—a man
+against whom the breath of suspicion had never
+been blown—to represent them in the opium
+market and the smuggled Chinamen market.
+They sent this man Emory to your son with a
+proposition, and he turned him down. Then
+they parted. But Albert knew too much and
+so he was lured to the woods and killed, and
+Emory stood before the world as your son. It
+was a devilish plot, great wealth being the object.
+If you will look at the stubs in this check-book
+you will see the difference in the hand-writing.”
+</p>
+<p>
+“I rather admire your nerve, boy,” Slocum
+said to Ned. “You’ve got the right kind of
+courage to stand up here and tell all this to us.
+You know very well that we can never let you
+go out of this place alive? That even this old
+man must suffer for your bit of foolish daring?”
+<span class='pagenum pncolor'><a id='page_250'></a>250</span>
+</p>
+<p>
+“I’d like to have the training of that kid for
+a few years,” Chang said. “I could beat the
+world with him!”
+</p>
+<p>
+“Well, you all know what we’ve got to do,”
+Emory said, angrily. “We’ve got to get rid of
+the boy and this old man. If we do not, there
+is an end of a rather profitable business. Besides,
+with Albert Lemon dead, I become his
+heir, with no possible chance of being identified
+as Felix Emory.”
+</p>
+<p>
+“You devil!” shouted the old man. “You
+murderer!”
+</p>
+<p>
+Enraged by the exclamation, Emory made
+a rush for the old man, but was stopped by a
+voice from the doorway opening into the rear
+room.
+</p>
+<p>
+“That’ll be all for you!” the voice said.
+</p>
+<p>
+It was Jimmie who stood in the doorway,
+smiling, and making about the worst bow a Boy
+Scout ever made.
+</p>
+<p>
+“Don’t wiggle about so, gentlemen,” he
+added, “for the men behind this partition have
+you all covered with repeating rifles, and some
+of them are nervous. Stand still while a friend
+of mine presents you with wristlets.”
+</p>
+<p>
+Jap turned and faced the frightened group
+and then pointed to the wall, near the ceiling,
+<span class='pagenum pncolor'><a id='page_251'></a>251</span>
+where a line of two-inch holes were seen, at each
+hole a shining eye.
+</p>
+<p>
+“You see,” he said, “I cut those holes there
+to-night, so the boys wouldn’t have to lie hidden
+under the furniture. There’s a gun behind
+every one of them. And now, with your permission—”
+</p>
+<p>
+Jimmie passed out a bunch of clattering,
+ringing handcuffs, and Jap slipped them on the
+wrists of the prisoners. As he did so Frank
+came dashing into the room, swinging his cap
+aloft. Ernest, Jack, Pat and Liu were there,
+too, overjoyed at the great victory.
+</p>
+<p>
+“Wow!” he cried. “Here’s a wire saying
+that the bunch was captured at Portland to-night,
+and another from Missoula says the men
+left in the caverns were caught yesterday. I
+have the honor to report, Mr. Sherlock Holmes
+Nestor,” he added, with a low bow, “that the
+round-up is complete.”
+</p>
+<p>
+“Our day will come directly,” Emory shouted.
+“You haven’t a word of proof against any
+of us. Your story sounds all right here, but
+wait until you get into court. Our lawyers will
+pick your yarn apart like a rag doll. And you,
+Jap,” he went on, turning to the servant, “when
+did you turn against me?”
+<span class='pagenum pncolor'><a id='page_252'></a>252</span>
+</p>
+<p>
+“There have been two instances of false personation
+in this case,” Ned said. “You, Emory,
+personated Albert Lemon, whom you murdered,
+and you, Jap, personated the servant Emory
+brought here after he had seen you carried out
+of the rooms for dead.”
+</p>
+<p>
+“Then that isn’t my servant at all?” asked
+Emory.
+</p>
+<p>
+“I was in the employ of Albert Lemon,”
+answered the Jap, “when you took him away
+and killed him. When you came back from the
+mountains you caused me to be drugged and
+killed, as you supposed. But your servant hesitated
+in the work. He finally turned against
+you, and permitted me to come here in his stead.
+It was he who disclosed the hiding place of the
+duplicate key. He told me, and I told Mr. Nestor.”
+</p>
+<p>
+“It is all a blackmailing conspiracy!” cried
+Emory.
+</p>
+<p>
+“When Mr. Nestor came back to the city,
+three days ago,” the servant went on, “I was
+told by the man I was personating in these
+rooms that the whole plot was known. He said
+that Mr. Nestor knew that you were not Albert
+Lemon, also that I, Albert Lemon’s servant, still
+<span class='pagenum pncolor'><a id='page_253'></a>253</span>
+lived. I didn’t have much to tell him when he
+came to me, but I told him all I knew.”
+</p>
+<p>
+“And you let him search my rooms?” cried
+Emory.
+</p>
+<p>
+“Of course,” was the cool reply. “He has
+everything required to send you to the gallows
+for the murder of Albert Lemon, and everything
+necessary in the case against the smugglers and
+firebugs, too. He found Emory’s servant,” he
+added, facing the father, “in a Japanese tea
+house, and brought him here to me after the
+closing scene was set for to-night. You may
+talk with him if you want to. He can tell you
+how the murder of your son was planned, also
+how the plot to kill Mr. Nestor in the mountains
+was laid—here in these rooms.”
+</p>
+<p>
+Again the old man sank into a chair and
+buried his face in his hands. It was a severe
+blow to him. He had arrived in San Francisco
+that day, anticipating a pleasant month with
+his son. And now to find him dead!
+</p>
+<p>
+“It would be interesting,” said Slocum,
+speaking for the first time since the arrests, “to
+know just how this remarkable boy discovered
+the connection between this flat and the mountain
+caves.”
+<span class='pagenum pncolor'><a id='page_254'></a>254</span>
+</p>
+<p>
+“The murder brought the clue,” Ned replied.
+“From the first the clue led here. And
+then the key without a stem, the smudge on
+Emory’s finger, the typewritten sheets, the machine
+in the mountains—oh, it was all easy
+enough after the discovery that this man Emory
+did not know where Albert Lemon kept his
+duplicate key to that desk!
+</p>
+<p>
+“The case is ended,” Ned continued, “and
+all the parties wanted by the law are under arrest,
+so, if you don’t mind, gentlemen, I’ll go
+to bed!”
+</p>
+<p>
+Jack, Pat, Ernest and Liu now advanced
+into the room and looked smilingly at their
+leader.
+</p>
+<p>
+“You can’t lose us,” Jack said. “If you
+don’t mind, we’ll take you back to the Rocky
+Mountains for a little fun with the aeroplane.
+I guess there won’t be any bold bad smugglers
+up there to distract our attention for a few
+weeks.”
+</p>
+<p>
+“And then,” Jimmie cut in, “I hope you’ll
+all go back to little old New York. I’m hungry
+and thirsty, and sleepy for a walk down the
+good old Bowery and the wise old White Way!”
+</p>
+<p>
+The case against Felix Emory was so complete
+that he pleaded guilty on being arraigned
+<span class='pagenum pncolor'><a id='page_255'></a>255</span>
+in court and was sentenced to the gallows.
+Chang received a long sentence for his connection
+with the murder, and the smugglers and
+firebugs were sent to prison for ten years each.
+</p>
+<p>
+The clean-up was so complete that Ned was
+requested to visit Washington and confer with
+the Secret Service chief regarding other cases.
+</p>
+<p>
+“But, after all,” he said, on leaving Jimmie
+and the other boys, including Ernest and Liu,
+in New York, “I don’t think I want any more
+fighting forest fires assignments in the Secret
+Service. We’ll go back some day and look over
+the ground, but I don’t think I’ll ever be able
+to get some of those rides in the air out of my
+mind.”

+By OWEN JONES and MARCUS WOODMAN
+</p>
+<p>
+With a Message to Boy Scouts by SIR BADEN-POWELL,
+Founder of the Boy Scouts’ Movement.
+</p>
+<p>
+One of the essential requirements of the Boy
+Scout training is a Knowledge of Woodcraft.
+This necessitates a book embracing
+all the subjects and treating on all the topics that
+a thorough knowledge of Woodcraft implies.
+</p>
+<p>
+This book thoroughly exhausts the subject. It imparts
+a comprehensive knowledge of woods from fungus
+growth to the most stately monarch of the forest;
+it treats of the habits and lairs of all the feathered and
+furry inhabitants of the woods. Shows how to trail
+wild animals; how to identify birds and beasts by
+their tracks, calls, etc. Tells how to forecast the
+weather, and in fact treats on every phase of nature
+with which a Boy Scout or any woodman or lover of
+nature should be familiar. The authorship guarantees
+its authenticity and reliability. Indispensable to “Boy
+Scouts” and others. Printed from large clear type on
+superior paper.
+</p>
+<p>
+Embellished With Over 100 Thumb Nail
+Illustrations Taken From Life.

+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.

+
+CHAPTER I.--A MOUNTAIN MYSTERY.
+
+
+On a sizzling hot afternoon near the middle of August, in the year
+nineteen eleven, three boys dressed in the khaki uniform of the Boy
+Scouts of America stood on a lofty plateau near the British frontier,
+watching with anxious eyes the broken country to the south and west.
+
+"Nothing stirring yet!" Jack Bosworth said, turning to Pat Mack and
+Frank Shaw, his companions. "Ned and Jimmie may be in trouble somewhere.
+I wish we had waited and traveled with them."
+
+"Traveled with them!" repeated Frank Shaw. "We couldn't travel with
+them. We were fired--given the grand bounce--twenty-three sign. Ned
+seemed to want the space in the atmosphere we occupied at Missoula.
+Serve them good and right if they do get distributed over the scenery."
+
+"Never you mind about Ned Nestor and Jimmie McGraw," Pat Mack put in.
+"They can get along all right if someone isn't leading them by the hand.
+Suppose we fix up the camp and get ready for our eats?"
+
+The boys turned away from the lip of the canyon upon which they had been
+standing and busied themselves putting up shelter tents and unpacking
+provisions and camping tools, as they called their blankets and cooking
+vessels.
+
+They had passed the previous night in a sheltered valley lower down,
+sleeping on the ground, under the stars, and had breakfasted from the
+scanty stock of eatables carried in their haversacks. Early that morning
+a train of burros had landed their outfit at the end of a rough trail
+some distance below, and the boys, with long labor and patience, had
+carried it up to the plateau.
+
+The men in charge of the burros had of course volunteered to assist in
+the work of carrying the goods to the place selected for the camp, but
+their offers had been declined with thanks, for the Boy Scouts were
+determined that for the present no outsider should know the exact
+location of their temporary mountain home.
+
+Those who have read the previous books of this series[1] will not be at
+a loss to understand why the location of the camp in the Northwest was
+for a time to remain a secret, so far as possible. Ned Nestor, for whom
+those on the plateau were now waiting, had, some months before that hot
+August afternoon, enlisted in the Secret Service of the United States
+government.
+
+Accompanied by Frank Shaw, Jack Bosworth, Jimmie McGraw and others, he
+had seen active diplomatic service during the Mexican revolution, had
+unearthed a plot against the government in the Panana Canal Zone, and
+had rendered signal service in the Philippines, where he had assisted in
+preventing an armed revolt against the supremacy of the United States
+government.
+
+At the close of his service in the Philippines, he had been commissioned
+to investigate forest fire conditions in the Great Northwest. The boy
+had a wonderful native talent for detective work, and, besides, it was
+thought by the officials in charge of the matter that a party of Boy
+Scouts, camping and roving about in northern Idaho and Montana and in
+the southern sections of British Columbia, would be better able to size
+up the forest fire situation than a party of foresters or government
+secret service men.
+
+So Ned and his four chums had sailed away from Manila, reached San
+Francisco in due season, and, after receiving further instructions and
+arranging for supplies, had headed for the frontier. At Missoula,
+Montana, he had sent Frank, Jack and Pat on ahead, after giving them the
+exact location of the future encampment and arranging for the
+transportation of supplies.
+
+From the first there had been some mystery in the minds of the three
+concerning Ned's strange halt at Missoula. They could not understand why
+he had sent them on ahead of him, for he usually directed every detail
+of their journeyings. When questioned concerning this innovation, Ned
+had only laughed and told the boys to keep out of the jaws of wild
+animals and not get lost.
+
+"I'll be in camp almost as soon as you are," he had said, "and will take
+the first mountain meal with you."
+
+Yet the boys had reached the vicinity of the chosen location on the
+previous day, and Ned had not made his appearance. Naturally the boys
+were more than anxious about the safety of their leader.
+
+"Did Ned say anything to you while at Missoula, about an aeroplane?"
+Jack asked of Frank as they unpacked bacon and corn meal. "You know,
+before we left the Philippines," he went on, slicing the bacon for the
+coming repast, "the officials said we were to have a government
+aeroplane. I was just wondering if the thing would get here after we
+have no use for it."
+
+"He said nothing to me about the arrival of the aeroplane," Frank
+replied, "but I presume he knows when the government air machine will be
+on hand. It may be packed up at Missoula, for all we know," he added,
+"and Ned may have waited there for the purpose of getting it ready for
+flight."
+
+"What the dickens can we do with an aeroplane in this wilderness?"
+demanded Pat, wiping the sweat from his face. "We can't run around among
+the trees with it, can we? Nor yet we can't get gasoline up here to run
+it with. Anyway, I'm no friend to these airships."
+
+"When they travel with upholstered dining coaches in connection, and
+sleeping cars on behind," laughed Jack, "you'll think they're all to the
+good. If we can't chase around among the trees in an aeroplane," he
+continued, "we can sail over the forests and high peaks, can't we?
+Without something of the sort, it would take us about a thousand years
+to get a look-in at this wild country."
+
+"Well," Pat grumbled, "I only hope we won't get our necks broken falling
+out of the contraption. It may be all right to go up in one of the
+foolish things, but I think I'd rather take chances on going over
+Niagara Falls in a rain-water barrel."
+
+"I half believe he will come in the aeroplane," Frank said, shading his
+eyes with his hand and looking out to the south. "He wants to surprise
+us, I take it, and that is why he acted so mysteriously about the
+matter."
+
+"What about Jimmie?" demanded Pat, who would take almost any risk on
+water, but who was filled with horror the moment his feet left the solid
+earth. "He can't bring Jimmie along in his pocket, can he? And even if
+he managed to get the little scamp up on the thing, some trick would be
+turned that would land the 'plane on top of a high tree."
+
+"Two can ride an aeroplane, all right," Frank insisted. "Anyway, quit
+your knocking. Ned knows what he is about, and we'll wait here for him
+if we have to remain until the Rocky Mountains wash down into the
+Pacific Ocean."
+
+"Suppose we climb up on the shelf above," Jack suggested, "and see if we
+can find anything in the sky that looks like an aeroplane. I really
+think Ned and Jimmie will travel here on the air line."
+
+Pat fished a field-glass out of his haversack and passed it over to
+Jack.
+
+"You boys go on up," he said, "and see what there is to be seen. I'll
+stay here and cook this bacon. I could eat a hog on foot right this
+minute. Where did you put those canned beans?"
+
+"Never you mind the canned beans," laughed Jack. "It will be time enough
+to open them when you get the bacon fried to a crisp. I see our finish
+if you got one of the bean cans opened. Say, but I could eat a peak off
+the divide!"
+
+"Well, the divide is up there, all right," Pat grinned, "go on up and
+take a bite off it. On this side that ridge away up there the rivers run
+into the Pacific ocean. On the other side they run into the Atlantic
+ocean. Split a drop when you get on top and send your best wishes to
+both oceans. And don't you remain away too long, either, for this bacon
+is going to be cooked in record-breaking time."
+
+Leaving Pat to prepare the supper, Frank and Jack turned their faces
+upward toward the main divide of the Rocky Mountains, 4,000 feet above
+their heads. It was a splendid scene, and they enjoyed it to the full.
+To the north the green forests of British Columbia stood crinkling under
+the almost direct rays of the August sun, to the east, almost over their
+heads, stood the backbone of the continent of North America, to the
+south stretched the broken land of Montana, while to the west lay the
+valleys and ridges of Idaho, Montana, and Washington beyond which pulsed
+the mighty swells of the Pacific.
+
+Immediately to the north of the position occupied by the camp, and
+within a mile of the international boundary line, Kintla lake lay like a
+mirror in the lap of the mountains, reflecting peaks and silent groves
+in its clear waters. From the lake, ten miles in length by half that in
+width, an outlet flowed westward into the North Branch of the Flathead
+river.
+
+The level plateau where the camp had been pitched was not far from two
+acres in extent, with the bulk of the mountain to the east, a drop of a
+thousand feet to the south, and steep but negotiable inclines to the
+west and north. The lake was 300 feet below the level of the plateau,
+which was about 3,000 feet above the sea level and 4,000 feet below the
+summit of the divide at that point in the long range of mountains.
+
+There were peaks to the north and south which showed eternal snow and
+ice, but there was a lowering of the shoulder of the great chain
+directly to the east, so there was no snow in sight there. There were
+forest trees low down in the canyon to the south, and on the slopes to
+the west and north, but the plateau and the sharp rise toward the summit
+were bare.
+
+While Pat sliced his bacon and mixed corn-meal, soda, salt and water to
+make hoecakes, to be fried in bacon grease, Frank and Jack wormed their
+way up the face of the mountain, toward a shelf of rock some hundred
+feet above the plateau. It was hard climbing, but the lads persisted,
+and soon gained the elevation they sought, from which it was hoped to
+gain a fine view of the country toward Missoula.
+
+"Good thing we don't want to go any farther," Frank exclaimed, throwing
+himself down on the ledge and wiping his streaming face. "We couldn't
+scale the wall ahead with a ladder. Now," he went on, "look out there to
+the south and see if there's an aeroplane in sight."
+
+Jack brought out the field-glass and looked long and anxiously, but
+there was no sign of a man-made bird in the clear sky.
+
+"I don't believe, after all, that he'll come in an aeroplane," the boy
+said, directly. "Suppose he took a notion to get a motor boat and run up
+the north branch of the Flathead river, and so on into Kintla lake, down
+there? How long would it take him to make the trip?"
+
+"About ten thousand years," was Frank's reply. "He never could get up
+the north branch. There's too many waterfalls. Why, man, the stream
+descends several thousand feet before it gets to sea level."
+
+"Anyway," Jack replied, "if you'll get out of my way I'll take a look at
+the lake through the glass."
+
+"You'll probably see him come sailing up the slope in a battleship,"
+Frank said, in a sarcastic tone.
+
+Jack, without speaking, turned his glass to the north and gazed long and
+anxiously over the lake. Presently Frank saw him give a start of
+surprise and lean forward, as if to get a closer view of some object
+which had come into the field of the lens.
+
+"What is it?" he asked.
+
+Jack passed him the glass with no word of explanation, and the boy
+hastily swept the shores of the mountain lake.
+
+"I don't see any motor boat," he said, directly.
+
+"Well, what do you see?" Jack asked, expectantly.
+
+"For one thing," Frank replied, "the smoke of a campfire."
+
+"I saw that, too," Jack said, "and didn't know what to make of it. Also,
+I saw a rowboat sneaking around that green point to the east."
+
+"That is what is puzzling me," Frank replied. "Years ago there was a
+Blackfoot reservation just over the divide, and a Flathead Indian
+reservation down by Flathead lake, to the south, but I had no idea the
+Indians were still about. Still, the people you saw were probably
+Indians. Suppose we go down there and look the matter up. We've got to
+have some sort of a yarn to tell Pat when we get back to camp."
+
+The two boys scrambled down almost vertical surfaces, edged along narrow
+ledges, slid down easier inclines, and finally came to the rim of beach
+about the lake. There, at the eastern end of the pretty body of water,
+they came upon the still glowing embers of a fire.
+
+Close to the spot where the remains of the fire glimmered in the hot
+air, they saw the mouth of a cavern which seemed to tunnel under the
+body of the mountain to the east. There were numerous tracks about the
+fire, and some of them led to the entrance to the cavern.
+
+"Whoever built this fire," Jack exclaimed, "wore big shoes, so it wasn't
+Indians. No, wait!" he added, in a moment, "there are tracks here which
+show no heel marks. What do you make of that?"
+
+"Must be moccasins," Frank said. "The Indians may still be in the woods
+about here."
+
+"I'm going into the cavern to see what's stirring there," Jack said,
+"and before I go I'll have a look at my artillery."
+
+The boy looked his revolver over, and before Frank could utter a
+warning, he darted away into the gloom of the cave. Frank did not follow
+him, but turned in the direction of the point where the boat had
+disappeared.
+
+A dozen yards on his way he stopped and listened. A voice, sounding like
+that of a person in a deep well, reached his ears, and he turned back.
+
+He gained the mouth of the cavern in half a minute and plunged inside.
+It was dark a dozen feet from the entrance, but he struck a match and
+moved on, finally coming to a smooth wall which appeared to shut off
+farther progress.
+
+When he turned about and faced the opening every object between where he
+stood and the mouth stood revealed against the bright sunshine outside.
+There were a few loose rocks, a rude bench, a small goods box, and
+nothing else. Jack was nowhere in eight.
+
+He examined the walls of the cavern but discovered no lateral passages.
+He called out to his chum, but received no response. Where was Jack? If
+he had left the cavern he would have been seen. It was a perplexing
+mystery, and the boy sat down on the box and listened for a repetition
+of the sounds he had heard.
+
+For a moment no sounds came, then a voice, seemingly coming out of the
+solid wall behind him reached his ears. He could distinguish no words
+for a time, and then it seemed that he was being called by name.
+
+He called to Jack again and again, but received no answer. Jack was
+evidently there somewhere, but where? The smooth walls gave no
+indication of any hidden openings, and there was in view no crevice
+through which a voice behind the walls might penetrate. It seemed either
+a silly joke or an impenetrable mystery.

+CHAPTER II.--THE SIGNAL IN THE SKY.
+
+
+Frank left the cavern in a moment and walked along the beach toward the
+campfire. His thought was to gather embers and fresh fuel and build up a
+blaze at the end of the cave which would reveal every inch of the
+interior. He was certain that Jack had not left the place, and decided
+that he had fallen into some hidden opening which had escaped his own
+investigation.
+
+As he bent over the remains of the fire he heard a rattle of small
+stones, and, looking up, saw Pat coming down the declivity from the
+plateau where the tents had been set up. The incline was steep, and at
+times Pat was rolling rather than walking. He was in his shirt sleeves
+and bareheaded. At last his red head pitched toward the lake like a
+meteor in downward flight.
+
+Frank rushed forward and caught him as he struck the beach, thus saving
+him from an impromptu bath. Pat struggled to his feet in an instant,
+rubbed his legs and arms to see if any bones had been broken, and then
+turned his head and looked up the incline.
+
+"Talk about shooting the chutes!" he exclaimed. "I wonder what time I
+made coming down?"
+
+"Sure you're not hurt?" asked Frank anxiously.
+
+"Every inch of my body has three bruises, one on top of the other," Pat
+replied, "but I guess I'm able to walk. Say, but that was a
+roller-coaster glide!"
+
+"Why did you try such a foolish caper?" asked Frank.
+
+"Why, I saw you boys here," was the reply, "and started down. You know
+the rest, as the yellow-covered books say. What you boys doing here,
+wasting your time, with the bacon burning to a crisp?"
+
+"We came here to investigate," was the reply, "and Jack went into the
+cavern, and vanished--just vapored into thin air. I'm going to build a
+fire in there and see if I can't condense him!"
+
+"Well," Pat said, listening, "he may have vanished physically, but his
+voice appears to be on deck yet."
+
+Three sharp calls came from the cavern, and both boys dashed inside.
+There was no doubt now that Jack's voice, at least, had condensed, for
+the shouts coming from the back of the cavern were both hearty and
+imperative.
+
+"Hi, there!" Jack called. "Pry this stone out of the doorway!"
+
+"Where are you?" demanded Pat. "Which one of the walls do you want us to
+push in? You're a nice chump, getting in a scrape like this!" he added,
+with a laugh which must have been exasperating to the unseen boy.
+
+"You'll find a crevice where the back of the cave joins the south wall,"
+Jack said, his voice coming faintly to the ears of his chums. "Put your
+fingers in and pull. The blooming door opens outward. Hurry! It's
+stifling in here!"
+
+After burning nearly all the matches they had in their pockets, and
+scorching their fingers on the short sticks, Pat and Frank discovered
+the crevice spoken of and inserted the ends of their fingers.
+
+"Pull!" yelled Jack. "Pull, you loafers! It is moving!"
+
+In a moment the south half of the back wall swung out so suddenly that
+both boys were thrown from their feet and Jack, who had been pushing
+with his whole strength, came tumbling on top of them as they lay on the
+floor of the cavern.
+
+"What sort of a combination is this, anyway?" demanded Pat, struggling
+to his feet. "If I get any more bumps to-day I'll be taking something
+that belongs to some one else. I've had my share."
+
+Frank sprang to the opening as soon as he could disentangle himself from
+the collection of arms and legs and looked in. All was dark and still
+inside, and a gust of dead air struck him in the face. Pat, leaning over
+his shoulder, laid a hand on the rock which had opened so strangely, and
+the next instant it closed softly, sliding into the opening like a door
+operated by well-oiled machinery.
+
+"Now you've done it!" Frank exclaimed, disgustedly, as Pat threw himself
+against the stone in a vain effort to force it open again.
+
+"No harm done," Jack exclaimed. "There's only a stinking cavern in
+there. Wow! I can feel snakes and lizzards crawling on me now! Come! Let
+us get into the open air. Stifles like a grave in here."
+
+The boys hastened outside and stood meditatively before the shining
+waters of the lake, each one trying to think clearly concerning what had
+taken place. They believed themselves--or had believed, rather--miles
+away from any trace of civilization, and yet here was a practical door
+of rock at the end of a cave almost under the great divide.
+
+"We've found something," Frank said, at length. "That thing in there
+never happened. Human hands fashioned that door for some secret purpose.
+And it wasn't Indians, either."
+
+"I guess we've run up against a band of train robbers," suggested Jack,
+with a grin.
+
+"Probably the entrance to some deserted mine," Pat put in. "This region
+has been searched for gold for fifty years. I've heard of mines being
+concealed by moving stones."
+
+"Well," Frank said, after a short silence, during which all listened for
+some indication of the immediate presence of the men who had been seen
+to row around the green point a short time before, "whatever the game
+is, we've got to remove every trace of our visit. When they come back
+they probably won't notice the tracks we have made, for there were
+plenty about before we came here, but we must gather up all the
+match-ends we left in there and leave the door as we found it."
+
+"I found it open and walked in," Jack said, "and then it closed. Whew! I
+felt like I was being shut up in a tomb!"
+
+"How large a place is it in there?" asked Pat.
+
+"Don't know," was the reply. "I had no matches with me, and so could not
+see a thing."
+
+"Then we won't have to open the door again to clean up any muss," Frank
+said, moving toward the entrance to the cavern.
+
+"I wouldn't go in again for a thousand dollars," Jack cried. "If you
+leave it to me, the place is haunted. I heard groans in there."
+
+Frank paused at the entrance and turned back. His matches were about
+gone, and so he took a burning stick from the fire, added two dry
+faggots to it, waited until the three burst into flame, and then entered
+the cave.
+
+To gather up the half-burned matches which had been scattered over the
+floor was the work of only a moment.
+
+"Now you'll have to open the door, if you leave it as I found it," Jack
+said, looking in from the mouth. "Pat will help you."
+
+"Come on in, both of you," Frank directed.
+
+"Not me!" cried Jack. "I hear bones rattling!"
+
+The boys thought he was joking at first, but it soon appeared that he
+was in sober earnest, so Pat and Frank, by exerting their entire
+strength, managed to open the door without his assistance.
+
+"You're afraid of the dark!" Pat taunted, as the boys gathered around
+the fire again.
+
+"I'm not half as afraid of the dark as you are of an aeroplane," Jack
+replied. "If I ever see you going up in a 'plane, I'll go in there
+alone."
+
+"Don't you ever forget that," Pat grinned.
+
+"Oh, I'll be game, all right," was the reply.
+
+Before leaving the beach for the camp the boys walked to the point
+around which the boat had gone and scanned the lake and its shores
+through the field-glass. There was no sign of life anywhere, except
+where the birds swung from forest limbs back from the rim of the lake
+and called each other through the sultry air.
+
+Reaching the camp after a weary climb, they did full justice to the meal
+which Pat had prepared, though the bacon and the hoecakes were stone
+cold, or at least as cold as anything could be in that glare of
+sunlight. Then, the dishes washed and the beds prepared for the night,
+they sat down to watch the lake and the sky to the south, for it was now
+the general belief that Ned would make his appearance with the aeroplane
+which had been promised by the government officials.
+
+The point they had last visited, as well as the location of the fire,
+was in full view of the plateau, so the boys made no efforts to conceal
+their presence there. The men who had been observed in the boat must
+have noted their presence on the plateau before taking their leave.
+Perhaps, they reasoned, they had taken their departure because of this
+invasion.
+
+The sun sank lower and lower in the sky, turning the plateau and the
+smooth waters of the lake to gold, still there were no signs of Ned, no
+indications of the return of the boat to the place from which it had
+been launched. Half an hour after dark, Frank, who was looking through
+the field-glass, caught sight of light in the south which did not appear
+to come from any star.
+
+"Here he comes!" he cried. "That's an aeroplane, all right!"
+
+As the light drew nearer, traveling rapidly, the sharp explosions of the
+gasoline engine became audible. Then a light flickered over the upper
+plane, passed off, and swept the white surface again.
+
+"How does he make that?" demanded Pat. "Looks like a great question
+mark."
+
+"That's what it is," Frank exclaimed. "Now, what does he mean by it?"
+
+
+
+
+Chapter III.--JUST A TYPEWRITER RIBBON.
+
+
+"I don't understand what question he is asking," Jack said, "but I know
+how he makes the signal. He has an electric flashlight, and he tips the
+plane--the upper plane--forward, like he was plunging to the earth, and
+writes the interrogation mark on the under side with the flame of the
+flashlight. See? Then it shines through the canvas and we read it! Great
+idea!"
+
+"That must be the way of it," Frank said, "but what does he want? And
+how does he expect us to answer?"
+
+"If I was up there in the dark on a contraption like that," Pat said,
+"I'd be asking how I was going to find a landing place."
+
+"Sure!" Frank cried. "Ned wants to know where we are, and whether it is
+safe for him to make a landing. Dunderheads! Why didn't we think of that
+before? He is passing now, and may not come back again."
+
+The light flashed by at swift speed, whirled, ascended several hundred
+feet, and came over the plateau, repeating the signal. Then it settled
+down into a steady circling of the camp.
+
+"He knows where we are, all right," Pat said. "What he wants to know is
+if it is safe for him to make a landing. If I ever go up in one of those
+things I'll drag a rope so I can climb down it."
+
+"I'll tell him what he wants to know," Frank said, "if you'll get me a
+long stick on fire most of its length."
+
+"Wigwag?" asked Jack.
+
+"Sure!" was the reply. "Now," Frank continued, "build four fires, one on
+each edge of the plateau. That will show him how large the place is.
+Then I'll take the flaming stick and wigwag o.k. Ned'll understand
+that."
+
+Pat watched the wigwag signal with interest.
+
+"I saw foolish signs like those in the Philippines," he said, with a
+grin. "The natives use them to talk treason to each other. I've heard
+that the same method is used by the East Indians who talk from one
+mountain top to another faster than words on a wire. How does he make
+the o.k. signal?"
+
+"O is one left, followed by one right," Jack replied, "and k is left,
+right, left, right. You won't think the signs are foolish when you see
+how quickly Ned reads them. See! He's shooting away now."
+
+"Perhaps he thinks the signals are being made by savages," Pat said.
+
+The aeroplane darted off to the west for half a minute, then whirled and
+came back. The boys could not see the great 'plane distinctly, but the
+lights which burned on the front were bright and clear, so they saw that
+the 'plane was sweeping toward the earth as it advanced in their
+direction.
+
+"I don't believe many professionals would care to make a landing like
+this," Frank said, as the machine dipped and slid to the ground, exactly
+in the center of the plateau.
+
+"Hello, Ned!" he yelled, as the aeroplane rolled over the smooth surface
+for an instant and stopped.
+
+In a second the three boys were gathered about the machine, pulling at
+the hands and feet of the daring riders. Jimmie McGraw bounded to the
+ground as soon as he could cast off the lines which had held him to his
+quivering seat.
+
+"Say," he cried, "you got a fire here? I'm most froze."
+
+Indeed the little fellow's teeth were chattering.
+
+"Cold?" echoed Pat. "We're melting down here. You're scared, that's
+what's the matter with you. You're scared stiff."
+
+Jimmie made a run for the speaker but brought up at the fire where the
+supper had been cooked.
+
+"Here's comfort!" he cried, extending his hands out over what was left
+of the small blaze. "The next time you get me up in the air I don't go!
+I've been freezing for an hour."
+
+In the meantime Ned Nestor was caring for the aeroplane, looking after
+the delicate machinery and covering it carefully with a huge oil-cloth.
+Pat stood watching the work with a grin on his face.
+
+"Are you thinking of giving me a ride in that thing?" he asked.
+
+"Not to-night!" laughed Ned.
+
+"Well, when you get ready for me to ride the air," Pat said, "just tell
+me the night before, and I'll shoo myself into the hills. If I'm going
+to fall off anything, I'll take the drop from something solid, like a
+mountain top."
+
+"No danger at all, when you know how to operate the machine," Ned
+replied. "There's danger in running anything if you don't know how, even
+a sewing machine."
+
+"Where did you pick it up?" asked Frank.
+
+"He didn't pick it up at all," interposed Pat. "It picked him up."
+
+"I found it at Missoula," was the reply, "all packed and stored away in
+a freight warehouse. I had to get it out at night, and so lost time. The
+people would have kept me there until now giving exhibitions if I had
+shown up during the day."
+
+"But you did leave there in the daytime," urged Jack. "You were never in
+the air since last night."
+
+"We left early this morning," was the reply, "and I was well up in the
+sky before many of the people saw me."
+
+"I never knew you could run one," Frank said.
+
+"Oh, I had some instructions from the Wrights," was the modest reply,
+"and, besides, there was an expert at Missoula who helped me get the
+machine together and contributed a few parting instructions."
+
+"Then you've been in the air all day?" asked Pat.
+
+"No, we stopped several times, of course, once on the right of way of
+the Great Northern railroad and filled our gasoline tanks," was the
+reply, "and rested there a few hours. Jimmie had to eat there, of
+course!"
+
+"Eat!" came the boy's voice from the fire. "If I ever get a bite at food
+again it will drop down into the toes of me shoes! Here!" he shouted, as
+Pat produced a can of pork and beans and started to open it. "You
+needn't mind opening that! I'll just swallow it as it is."
+
+"Bright boy!" laughed Pat, handing him a liberal supply of beans and
+fried bacon. "Now fill up on that and then loosen up on your impressions
+of the sky."
+
+"I thought I'd make an impression on the earth before I got through,"
+Jimmie mumbled, his mouth full of beans. "We went up so far that the
+mountains looked like ant hills, didn't we, Ned?"
+
+"About 7,000 feet," was the reply. "You see," he added, turning to
+Frank, "I wanted to size up the situation before I landed. If there is
+anybody in this upturned country at all, our presence here is known. The
+aeroplane's chatter took good care of that. And, besides, our landing in
+the night, with the lights going, gave unmistakable evidence of
+something stirring."
+
+"I should say so," Frank agreed.
+
+"And so," Ned went on, "I wanted to learn if there were people about
+here, so I might visit them in the morning and put up the bluff of Boy
+Scouts playing with an aeroplane in the woods. We can't attempt anything
+in the mysterious line," he went on. "We've got to be entirely frank
+about everything except the business we are here on."
+
+"Well," Frank said, "we found people here to-day and called on them."
+
+"What sort of people?"
+
+"Well, they seemed to have good broad backs," laughed Frank.
+
+"They ran away from you?" asked Ned, in surprise. "I should think they
+would have proved inquisitive. Where were they?"
+
+"Down by Kintla lake."
+
+"Indians?" asked Ned.
+
+Then Frank told the story of the visit to the shore of the lake and the
+cavern, taking good care to describe the surroundings as closely as
+possible. Ned laughed when the boy came to Jack's adventure in the
+hidden chamber.
+
+"I say it is some deserted mine," Pat declared, when Frank had concluded
+the recital. "What else could it be?"
+
+"Robber's nest!" suggested Jack.
+
+Ned remained silent for a moment and then abruptly asked:
+
+"What kind of footwear made those heelless prints?"
+
+"You may search me!" Jack cut in.
+
+"Must have been Indian moccasins," Frank observed.
+
+Jimmie, who had been standing by the small fire, listening to the talk,
+now advanced to the little circle about the machine and uttered one
+word: "Chinks!"
+
+"It is always Chinks with Jimmie," grinned Frank. "When there is a
+cyclone in New York the Chinks are to blame for it, if you leave it to
+him."
+
+"What would Chinks be doing up here?" demanded Pat.
+
+"Don't they get gold by washing it out?" asked Jack, with a nudge at
+Jimmie's side. "Perhaps they're going to start a laundry!"
+
+While this chaff was in progress Ned stood looking thoughtfully in the
+direction of the lake. Not a word did he say regarding the sudden and
+brief communication Jimmie had presented.
+
+"Any forest fires in sight?" asked Pat, finally breaking the silence.
+
+"Not one," Jimmie answered. "I would have dropped into one if it had
+come my way. It was fierce up there!"
+
+"It is rather cool when you get up a couple of miles," Ned laughed, "and
+Jimmie wouldn't listen to reason regarding his clothes. To-morrow I'll
+give one of you boys a ride, and you may see for yourself."
+
+"Not me!" Pat exclaimed. "I'll stay below and help pick up the pieces."
+
+"I should like to go," Frank said. "We may find the people we saw in the
+rowboat. When we become acquainted with them we may be able to learn
+something about that cavern."
+
+"I would advise remaining silent about the cavern," Ned said. "It may be
+used for some criminal purpose, and we must not admit that we know of
+its existence. We are just carefree lads, here for an outing, remember,"
+he added, with a laugh, "and we are due to make friends with everybody
+we come across."
+
+"But you made us lug all this camping outfit up here," complained Jack,
+"so the men who steered the burros up the hills wouldn't know where we
+camped. What about that?"
+
+"I thought it best to cut off all communication with the people below,"
+explained Ned. "It may be that the purpose of our visit here is
+suspected. In that case some one from below might want to find us--for
+no good purpose. So we'll keep out of sight of the people in the towns,
+unless they see our aeroplane, and cultivate the acquaintance of the
+natives--if there are any."
+
+"How about gasoline and provisions?" asked Pat.
+
+"I have plenty of gasoline stored on the right of way of the Great
+Northern railroad," Ned replied, "enough to last us a month. It was
+piped into a hidden tank from an oil car by a train crew now out of the
+state. We are to get provisions at the same place, if we need more, for
+Uncle Sam fixed all the details for us. All we have to do is to find the
+fellows who are setting forest fires and bring them to punishment."
+
+"We ought to locate every little smudge, with that aeroplane," Frank
+suggested.
+
+"That is my idea," Ned replied. "Have you been keeping a good lookout on
+the lake since you left it?" he added, turning to Pat.
+
+"Some one of us has had eyes on it every minute," was the satisfactory
+reply. "No one has returned, I'm sure."
+
+"You're not thinking of going there to-night, are you?" asked Jack, with
+a slight shiver. "I wouldn't go in there again, even in broad daylight,
+for a million dollars!"
+
+"Pat is afraid of the sky, and Jack is afraid of the bowels of the
+earth!" laughed Frank. "We'll have to tuck them both in bed before we
+can accomplish anything."
+
+"You may all go to bed but one," Ned said, looking about the group, his
+eyes finally resting with a significant look on Frank's excited face. "I
+want to look through that cavern before anything is taken out of it."
+
+Frank, knowing the meaning of the look he had received, went to his
+little tent for his revolver and his electric searchlight and was soon
+ready for the expedition. Jimmie looked sulky for a moment at being left
+out of the game, then his face brightened and he crawled into the tent
+that had been prepared for Nestor and himself and burst into a fit of
+laughter.
+
+"I'll show 'em!" he said, stuffing the blanket into his mouth to
+suppress the sound of his merriment. "I'll teach 'em to put me in the
+discard."
+
+"Any wild animals up here?" asked Ned, as the two started away down the
+steep declivity.
+
+"Two Black Bears and three Wolves!" called Jimmie, from his tent.
+
+This was a reference to the Boy Scout Patrols to which the boys
+belonged. Frank and Jack were members of the famous Black Bear Patrol of
+New York City, while Ned, Pat and Jimmie were members of the Wolf
+Patrol.
+
+As the lad spoke Frank and Jack broke into growls which might well have
+come from the throat of the grizzliest grizzly in the Rocky Mountains,
+while Pat sent forth a wolf howl, which might well have been a signal to
+the pack.
+
+"You may meet the real thing out here," warned Ned, turning back to look
+over the plateau, now shining in the light of a half-moon. "There are
+both bears and wolves in this region. When you meet them, don't wait for
+Boy Scout signs!"
+
+"Oh, we'll initiate 'em, all right," Jimmie called from the tent, and
+Ned and Frank moved on down the declivity toward the lake.
+
+It was still early evening, and the moon was low down in the east, so
+the valley where the lake lay was not touched by its light. Indeed, the
+plateau where the boys were would have been in the shadow of the
+mountain only for the dropping of the shoulder of the divide.
+
+In half an hour the two boys, after several slides which were anything
+but pleasant, gained the beach. The campfire was now dead, and the
+locality was still save for the voice of a night bird and the occasional
+splash of a leaping fish. The mouth of the cavern loomed like a dark
+patch on the lower bulk of the mountain.
+
+Making as little noise as possible, Ned and Frank crept into the cavern,
+advancing by the sense of feeling until they came to the very end before
+turning on one of the electric flashlights. The round eye of the flame
+showed a long, narrow, tunnel-like tube running directly east, under the
+mountain. The door of rock was as the boys had left it earlier in the
+day.
+
+Ned examined that portion of the rock which had swung out into the first
+chamber with considerable care, as the story of the swinging stone had
+interested him greatly. All along the top, up to the center, he found
+the checks of a stone-chisel. Exactly in the middle an elevation of an
+inch fitted into a round cavity in the upper rock. At the bottom the
+same conditions were discovered.
+
+"Rather a clever job," Ned said, "but I don't see how it was ever done."
+
+"This door," Frank said, "is not exactly like the remainder of the wall
+in grain, so it must have been brought here from some other locality. Of
+course there was a hole between these two chambers, or the second one
+would never have been found. It would be easy enough to fit the stone
+door in by grooving out from the lower cavity and sliding the under
+pivot in."
+
+"Sure," Ned replied, getting down to examine the lower part of the door
+more closely, "and that is just what was done. Then the groove was
+filled with concrete. Pretty classy work here!"
+
+"And now the question is this," Frank went on, "what was the door fitted
+for? Why did the men who found the cave desire privacy? Is there gold in
+there? Have the men who have been setting fire to the forests
+established a home here? Is this the hiding place of a band of outlaws?
+You see there are lots of questions to ask about the two caverns," Frank
+added, with an uneasy laugh.
+
+Ned closed the stone door and turned on both electric flashlights,
+making the place light as day where they stood. The inner cavern was as
+bare as the outer one save for dead leaves and grass which lay in heaps
+on the stone floor, and for half a dozen rough benches which were piled
+in one corner. At the farther end hung a gaudy curtain, once handsome,
+but now sadly spotted with mildew because of dampness.
+
+"Here's the inner chamber," laughed Frank, drawing the curtain aside.
+"And it looks like it was the private office of the bunch, too," he
+added, as he turned the light about the walls.
+
+There was a desk in the third cavern, a swivel chair, a small case of
+books, and a rusty safe, which looked as though it had not been opened
+for years. A current of fresh air came from the rear, and a small
+opening was soon discovered.
+
+"That doubtless leads to some canyon not far away," Ned said. "Makes a
+pretty decent place of it, eh?"
+
+"Good enough for any person to hide in," replied Frank. "Now," he added,
+"tell me what you think of it. Who cut this cavern, and who brought the
+furniture here? I'll admit that my thinker is not working."
+
+"Nature made the caverns," Ned replied. "There is what geologists call a
+fault in the rock here. Owing to volcanic action, doubtless, the strata
+shifted, probably thousands of years ago, and when the seam appeared the
+broken pieces fell apart. These chambers show the width of the seam.
+There undoubtedly was a great earthquake at the time, and the lake below
+might have been dredged out at that time."
+
+"Of course," Frank said, "I might have known that! Now, here's another
+question: How far does this seam extend under the Rocky Mountains? If it
+passes beyond these three chambers, why not make a fourth room for
+ourselves so as to be on the spot when the men who make headquarters of
+the place come back?"
+
+"That may be a good thing to do," Ned admitted, "but, still, I would not
+like to be the one to lie in wait here. Suppose we try to learn
+something of the character of the people who come here? They seem to
+sleep on dry leaves and eat off benches. Rather tough bunch, I take it.
+Perhaps we have struck Uncle Sam's enemies the first thing!"
+
+Keeping their lights on, and working as silently as possible, always
+with an eye to the outer cavern, the boys made a careful search of the
+inner chamber. The desk was not fastened, and a cupboard afterward
+discovered in a niche was open also. There were dishes in the cupboard
+and writing materials in the desk.
+
+At the very bottom of the desk drawer Ned came upon a surprise.
+
+"Not so tough as I supposed," he said, turning to Frank. "Here's a
+typewriter ribbon. The sort of people who set fire to forests and hold
+up trains are hardly in the typewriter class. What do you make of it?"
+
+"Well," Frank said, with a chuckle, "if you'll tell me what the
+inhabitants of this place want of typewriter ribbons I'll tell you why
+they bring great tins of opium here. It seems that we have struck
+something more important than forest fires."
+
+
+
+
+CHAPTER IV.--THE AEROPLANE IN DANGER.
+
+
+A strong wind came out of the Western Sea at ten o'clock that night and
+swept the lofty plateau as a woman might have swept it with a new broom.
+Ned and Frank, pursuing their investigations in the cavern, knew nothing
+of what was going on at the camp, but Jack and Pat were not long in
+ignorance of the danger of the situation.
+
+With the first strong rush of wind the boys were on their feet,
+steadying the aeroplane, driving stakes wherever the nature of the
+ground permitted, and running bracing cords. The shelter tents went down
+instantly and were blown against the rocks of the east, where they waved
+canvas arms in the tearing breeze like sheeted ghosts.
+
+The black clouds which swarmed up from the valley brought no rain, but
+fitful flashes of lightning and deep-toned thunder made a threatening
+sky. The roaring of the swirling trees in the canyon and on the slopes
+came up to the ears of the boys like the boom of a strong surf.
+
+After persistent efforts the boys succeeded in bracing the aeroplane so
+that there was little danger of its being swept away, though they still
+remained with their backs to the wind, holding on. As time passed, they
+crept close together in order that the situation might be discussed.
+
+"Lucky thing we remained here," Pat said, tugging with all his might to
+steady the monster machine against a particularly vicious dash of wind.
+
+"It would have gone sure, if we hadn't," Jack screamed back. "I wish Ned
+and Frank would come and help. My back is creaking like a shaft that
+needs oiling with the strain on it."
+
+"A little help wouldn't go amiss," Pat admitted, shouting at the top of
+his lungs in order that he might be heard above the whistling of the
+storm.
+
+"I wonder if we'll ever be able to put the tents up again?" Jack
+shouted. "They are flapping and snapping like musketry out there on the
+rocks. I hope they won't blow away entirely."
+
+Pat gazed anxiously in the direction indicated, but could only see
+pieces of canvas bellying up in the wind, mounting upward like balloons
+at times, then falling back to earth when a short lull came in the
+storm.
+
+"Why," he cried, in a moment, "where's Jimmie? I thought I saw him here
+a moment ago. Have you seen him?"
+
+"Not since the storm," panted Jack.
+
+"He may have been smothered in his tent," Pat shouted. "You hold on here
+while I go and look him up."
+
+"Be sure that you keep close to the ground," warned Jack. "If you don't
+you'll be blown away."
+
+It was not at all difficult for the lad to reach the flapping tents, for
+the wind generously assisted him in the journey. Only that he crept on
+his hands and knees he would have been tossed against the wall where the
+tents lay.
+
+Struggling with the tearing canvas, bracing himself against the face of
+the cliff, the boy looked over the ruined tents but found no indication
+of the presence of the boy he sought, either dead or alive. Then he felt
+along the angle of the foot of the rise with no better success.
+
+"He's not there," he reported, crawling back to Jack, now braced
+tenaciously with his toes and elbows digging into the soil above the
+rock.
+
+"Did you find his clothes?" asked Jack.
+
+"Not a thing belonging to his outfit," was the reply.
+
+"Well, he went to bed, didn't he?" asked Jack, a sudden suspicion
+entering his mind.
+
+"He went into his tent," was the reply, "but I did not see him undress."
+
+Then Pat, much to his astonishment, heard Jack laughing as if mightily
+pleased over something that had taken place.
+
+"You've got your nerve!" he exclaimed. "Laughing at a time like this.
+I'll bet the kid has been blown off the plateau."
+
+There was now a little lull in the drive of the wind and Jack nudged his
+companion with his elbow, turning an amused face as he did so.
+
+"Blown off nothing!" he said. "You saw how he acted when Ned went off
+without him--how sulky he was?"
+
+"I noticed something of the sort."
+
+"Well, Jimmie ducked after him!"
+
+"Why, he was told to remain here."
+
+"He has been told that before," Jack said, "and he's never obeyed
+orders. He followed Ned from Manila to Yokohama, not long ago, and made
+a hit in doing it, too. Oh, it is a sure thing that Jimmie is not far
+from Ned at this minute."
+
+"The little scamp!" grinned Pat.
+
+"He seems to think that Ned can't get along without his constant
+presence and his pranks," Jack continued. "He generally stirs something
+up in his immediate vicinity, but he's a pretty good scout at that."
+
+"I hope he is with Ned," Pat said.
+
+The wind now died down a bit, so that it was no longer necessary to hold
+the aeroplane, and the boys, after seeing that the rope still held,
+began the work of repairing the tents.
+
+The clouds drifted away and the moon looked down as bravely as if it had
+not just hidden its face from sight at the threats of the wind! The
+electric flashlights with which the boys were well provided seemed
+inadequate and Pat started in to build a fire.
+
+"I don't know about that," Jack said. "If there had been a fire here
+when that wind came up it would have been roaring in the canyon now. The
+storm would have swept it down on the trees there, and the whole gully
+would soon have become a roaring furnace. Better cut out the fire."
+
+"I guess you are right," Pat said, reluctantly laying his dry faggots
+aside.
+
+While the boys worked, trying to restore the shelter tents to something
+like form, the wind came up once more and reached out for the aeroplane.
+Pat and Jack renewed their holding efforts, and thanked their stars that
+no fire had been built on the plateau, for the forest about was dry as
+tinder.
+
+Presently a voice which neither recognized came out of the shadows cast
+by a mass of clouds just then occupying the sky where the moon should
+have been.
+
+"Hello!" the voice said.
+
+The boys looked at each other in perplexity for a moment and then Jack
+answered back.
+
+"Hello!" he said.
+
+"Are you all safe up here, safe and sound?" the voice asked, and then
+the figure of a tall man, roughly dressed, but bearing the manner, as
+faintly observed in the darkness, of a gentleman, advanced toward the
+aeroplane, to which the lads were still devoting their whole attention.
+
+"Safe and sound!" repeated Pat.
+
+The stranger sat down by Jack's side and laid hold of the aeroplane.
+
+"Pulls hard, doesn't it?" he asked, as the machine, forced by the wind,
+drew stoutly on the ropes and the muscles of the boys.
+
+[Illustration: ILLUSTRATION No. 2]
+
+"Pulls like a horse," Jack replied.
+
+"I'm Greer, of the forest service," the stranger said, in a moment. "I
+saw a fire up here this afternoon, and I was afraid harm might come from
+it during the gale. One blazing brand down in that canyon, and millions
+of feet of timber would be destroyed."
+
+"As you see," Jack said, "we have no fire."
+
+"This, I presume," Greer said, still pulling at the machine, "is the
+aeroplane your friends came in this evening?"
+
+"The same," replied Pat shortly.
+
+The lad was annoyed to think that the forester, as he called himself,
+had been watching them. If he had taken so much interest in their
+movements, Pat thought, why hadn't he shown himself before?
+
+Jack's thoughts seemed to be running in the same direction. In fact,
+both boys were suspicious of this soft-spoken stranger who had come to
+them out of the storm with questions on his lips.
+
+"Where are your friends?" Greer asked, in a moment. "I hope they are not
+out in the forest thinking of starting a fire?"
+
+"They've gone to the lake after fish," Jack said, accounting for the
+absence of the others with the first words that came to his lips.
+
+Greer gave a quick start and leaned over to look into Jack's face.
+
+"Down at the lake?" he repeated. "Not out in a boat in a storm like
+this?"
+
+"No," replied Jack, gruffly, so gruffly, in fact, that the stranger
+caught the hostile note and turned away.
+
+"I'm always afraid of fire on a night like this," Greer continued in a
+moment, "and rarely sleep until morning. My cabin is back on the
+mountain a short distance, some distance above this plateau. That's how
+I happened to see what was going on here."
+
+"Rather a lonely life," Pat said, resolved to keep the fellow talking if
+he could. "Because," he reasoned, "you can tell what's in a man's head
+if he keeps his mouth open and his tongue moving, but no one can tell
+the secret locked up behind closed lips."
+
+"Yes, it is rather lonely," Greer replied. "I'm glad you boys are here.
+Going to remain long?"
+
+"Only a few weeks--just to hunt and fish," was Jack's reply.
+
+"If you don't mind," Greer went on, "I'll come down and visit you now
+and then."
+
+The statement almost took the form of a question, and Jack gave a
+grudging answer that the visits would be a pleasure, though he believed
+that the man was arranging a way of watching their movements.
+
+"I wish this wind would go down," Greer said, presently. "As I said
+before, I'm always afraid of fire on nights like this. See! The wind
+blows straight off the distant ocean strong and steady, and a fire
+started out there to the west would run over this plateau and over the
+mountain like a wash of tide."
+
+"There's nothing to burn on the plateau," Jack said, glad of an
+opportunity to contradict the stranger.
+
+"Nothing to burn!" Greer repeated. "I reckon you don't know much about
+forest fires, young man! Why, it would burn the soil down to bed rock,
+even evaporate the water in the rock itself and crumble it down to
+ashes. A forest fire is no joking matter."
+
+The boys remained silent, looking cautiously into each other's faces and
+both wondering how a forester, a man marooned in a great wilderness
+should be so exact in his speech, should wear such a shirt--actually a
+dress shirt--as they saw under his rough coat when the wind blew it
+aside.
+
+"I rather think there's more company coming," Greer continued, seeing
+that the boys were not inclined to comment on his warnings. "A moment
+ago I saw a flash of light at the foot of the rise to the west."
+
+The wind was still blowing fiercely, but both boys turned and looked
+down the incline. There was a faint light there now, glimmering among
+the trees.
+
+"It looks like a lantern," Greer said. "And the fellow seems about to
+climb the hill. Good luck to him, in this gale."
+
+"It seems to me," Pat said, "that the light we see is running along on
+the ground. If that should be a forest fire, there would be the dickens
+to pay to-night--and nothing to pay with!"
+
+"That is not the way forest fires start," Greer said, turning indolently
+in the direction of the divide. "That is a man with a lantern."
+
+The boys watched the glimmer below with interest. The man with the
+lantern, if there was a man and a lantern, seemed to be moving with the
+wind. Then, again, he seemed to divide himself, as the lower orders of
+life at the bottom of the seas divide themselves, appearing on both
+sides of a dark space at the same moment.
+
+They were satisfied that something unusual was going on, but were for
+the moment lulled into a half-sense of security by the positive
+assertions of the alleged forester. Presently they turned away from the
+scene below and fixed their eyes on the stranger.
+
+He was standing straight up, his tall figure braced against the wind,
+peering down into the canyon. Notwithstanding the steady wind, the sky
+was now comparatively free of clouds, and they saw him lift a hand with
+something bright shining in it.
+
+It appeared to the lads that he was signaling to some one in the canyon.
+They turned away instantly so that Greer did not note their observation
+of him, and again fixed their gaze on the slope to the west.
+
+The lantern, if there was a lantern, was growing larger! It was showing
+itself in half a dozen places now, and was tracing lights far up in the
+crotches of dead trees. Then the penetrating odor of burning wood and
+grass came up the slope.
+
+Filled with a fear which could hardly be expressed in words, the boys
+faced Greer again. He still stood facing the canyon to the south, but his
+hands were not lifted now. There was no need for that, the boys thought,
+for the previous signal seemed to have sufficed.
+
+Among the dry faggots on the ground at the bottom of the canyon there was
+another man with a lantern. He, too, if there was such a man, was moving
+about among the trees and dividing himself into sections, as the
+rudimental creatures of the world multiply themselves. Pat sprang to
+Greer's side and shook him roughly by the arm.
+
+"There's a fire down there!" he cried.
+
+In the uncertain moonlight the boy saw the stranger's face harden.
+
+"You are mistaken," he said, turning away toward the lake.
+
+"Smell the smoke!" Jack shouted. "I tell you the forest is on fire on
+two sides of us."
+
+"Then your friends have set the fires!" Greer shouted, against the wind.
+"I have been suspicious of you all along--ever since you failed to
+satisfactorily account for the absence of your friends. It is all very
+well for you to come here in an aeroplane and start a conflagration! But
+how do you think that we, who are not so well provided with means of
+getting away, are to escape death?"
+
+Pat drew back his hand, as if to strike the fellow, but Jack restrained
+him.
+
+"You set the fires!" Pat shouted, then. "You set it through your fellow
+conspirators! I saw you signaling to the canon!"
+
+"You're no more a forester than I am!" Jack added. "You're a scoundrel,
+and ought to be sent to prison for life."
+
+There was no more talk for a time. Greer stood defiantly against the
+wall of rock to the east, as if fearful of an attack from behind, his
+right hand in his bulging pocket. The boys knew that he had a weapon
+there, and their own hands were not empty.
+
+The aeroplane drew and shivered in the rising gale, but now little
+attention was paid to it. Pat and Jack were listening for some
+indication of the return of Ned and Frank. No farther fable of a man
+with a lantern was necessary, for fire was racing up the western slope,
+heading directly for the plateau and the priceless aeroplane. Down in
+the canyon the flames were leaping from tree to tree. A stifling smoke
+filled the air, always in swift motion, but stifling still.
+
+
+
+
+CHAPTER V.--THE REVELATION OF A TRAGEDY.
+
+
+"Smugglers!" Frank exclaimed, dropping an armful of unopened opium tins
+on the floor of the cavern. "Smugglers, all right, all right!"
+
+Ned looked the tins over carefully. They were well covered with Chinese
+characters, and were dirty, as if they had been hidden away in the earth
+for a long time.
+
+"Who would have suspected it?" Frank continued. "We are close to the
+British frontier, but, all the same, this seems to me to be an awkward
+place to land and store the dope stuff."
+
+"Where did you find it?" asked Ned.
+
+"There is a false back to that cupboard in the north wall," Frank
+replied. "When I knocked on the boards they gave forth a hollow sound,
+and so I tore one away. Hence the opium. And there are pipes there,
+too--just such pipes as one sees in the joints on Pell street, in little
+old New York."
+
+"You remember what Jimmie said?" asked Ned.
+
+"I remember a good many things the little rascal has said," was the
+laughing reply. "He's always saying something."
+
+"Well," Ned continued, "the boy was right when he expressed his opinion
+of the heelless footprints in one word."
+
+"Chinks!" grinned Frank. "Of course!"
+
+The boys now went over to the cupboard in the niche and began tearing
+away the boards. After a few had been displaced Ned stopped and began
+experimenting in fitting them in position again.
+
+"What's doing now?" demanded Frank.
+
+"We must remove them so as to be able to return them as we found them
+before we leave," Ned replied. "It is important that the inhabitants of
+this robber den do not know that we have discovered it."
+
+"Don't you ever think they don't know it right now," Frank said. "We
+haven't seen any of them since they rowed around the point, but they're
+stirring about, just the same. We may see more of them before we get out
+of this cavern."
+
+"Well," Ned said, "we must take all the precautions needful, and if they
+are of no avail we shall not be to blame for what takes place. Even if
+they know that we have found the cavern, they need not know that we have
+penetrated into the office chamber. Now, draw that last board away
+carefully, and we'll see what there is behind the false bottom."
+
+Frank drew the board away and was confronted by a long, low tunnel--an
+uncanny, narrow tunnel which had evidently been enlarged from a fault in
+the rock, and which appeared to penetrate far into the bulk of the
+mountain.
+
+"See!" he cried. "The cupboard was built at the mouth of a cross fault
+in the rock, and there is no knowing what is behind it. Hold your
+flashlight higher and I'll crawl in and look about."
+
+"Be careful," Ned warned. "I have seen great holes at the bottom of
+tunnels like that. Don't break your neck, or tumble down so far that I
+can't fish you out."
+
+Frank grinned and crept through the opening made by the removal of the
+back of the closet. The place was not high enough for him to stand
+upright, and so he proceeded on hands and knees.
+
+"This is a bedroom," he shouted back to Ned. "There's lots of ticks and
+blankets here."
+
+There was silence for a moment, and then the boy's voice came from
+farther in the tunnel. "And here's kegs of whisky," he cried. "It smells
+like a Bowery saloon. Come on in!"
+
+"I think one of us would better remain outside," Ned replied. "I
+wouldn't like to be surprised while in there and fastened in with
+rocks."
+
+Frank went on down the tunnel for some distance, calling back, now and
+then, to report his discoveries. There were weapons stored there,
+barrels of gasoline, packages of dynamite.
+
+Then, for several long minutes, there came no voice from the interior,
+and Ned put his head inside and called out softly:
+
+"Frank!"
+
+There was no reply, and Ned was about to advance into the opening when
+the sound of a footstep came on the rocky floor of the chamber just
+behind him. The footstep was a stealthy one, halting, as if some person
+were listening between the steps. Ned's first act was to shut the light
+off from his electric candle.
+
+Then he moved away from the niche in the wall where the cupboard had
+been built in and waited. His greatest fear was that Frank would turn
+about and show his light, and so expose them both to danger. While he
+listened, almost holding his breath, the steps came nearer to the
+cupboard and halted.
+
+But the halt was only for an instant, for the unseen figure moved on
+again, this time back toward the entrance. Directly the footsteps were
+heard no more, and then the crash of falling rocks reached the boy's
+ears. He did not have to think long in order to understand what that
+sound portended.
+
+He knew that they had been observed by some of the outlaws who made the
+cavern their home and their storehouse as well, had been followed into
+the inner chamber, and were now to be fastened into the cavern, probably
+left there to starve, with tons of rock bulking before the entrance to
+the third chamber. It was not a pleasant situation.
+
+While he studied the peril over in as optimistic a mood as was possible
+under the circumstances, he heard Frank calling to him from the narrow
+tunnel behind the cupboard. The boy was evidently excited, for his voice
+rang high.
+
+"Ned!" he cried. "Come on in!"
+
+The noise of falling, rolling rocks stopped at the sound of Frank's
+voice, and Ned thought he heard a half-suppressed chuckle in the
+darkness.
+
+"Hurry!" came Frank's voice once more. "There's something in here that
+takes the nerve out of me."
+
+There was a low exclamation of rage at the entrance, where the stones
+were piling up, and then the grind of falling rocks was continued. Ned
+had, of course, no idea as to how many persons were engaged in building
+up the wall which threatened to shut him in until life was extinct, or
+exactly how it was being done, but he knew that the correct thing for
+him to do was to prevent the completion of the work.
+
+If only one man had arrived at the cavern he might be frightened and
+driven away by a little shooting. With bullets whizzing through what was
+left of the opening, the man who was building the crude wall would not
+be likely to present his body before the space still uncovered. This
+reasoning brought the boy to a consideration of the matter of
+ammunition, but he decided that, with the cartridges carried by Frank,
+they could defend the place for a long time.
+
+But another question intervened. The rocks which, though unseen, he knew
+to be blocking the space where the rug had hung were undoubtedly falling
+from a distance. They might have been stored above the natural doorway
+for the very purpose to which they were now being put.
+
+If this were true, then the building of the trap would continue,
+regardless of his bullets. While he studied over this problem, slowly
+making up his mind to put it to the test, Frank's voice came from the
+tunnel again.
+
+"What's doing out there?" the boy asked. "Why don't you come in here?"
+
+"Shut off your light!" ordered Ned, as a glimmer showed inside.
+
+"Not me," replied Frank. "I need all the light I can get in here!"
+
+"What have you found?" asked Ned anxiously.
+
+Frank did not reply instantly, and Ned heard the rattle of stones while
+he waited for his answer. The task of piling up the wall was progressing
+rapidly, and it seemed to the boy that the stones were all falling from
+a distance.
+
+"Shut off your light and come out," Ned said, impatient at the
+hesitation.
+
+"I wouldn't stay here in the dark for a thousand dollars a second,"
+Frank replied, "but I'll come out. Why don't you show a light?"
+
+"I'm not looking for any chance bullets," Ned replied, coolly. "We're
+caught, my boy, and it is up to us to move cautiously. Why don't you
+turn off your light?" he added, half angrily.
+
+"Oh," Frank replied, "you're getting it out there, too, are you? Well, I
+was trying to save you a shock. There's a dead man in here, and I'm
+going to keep my light going until I'm out of the hole. I did shut it
+off once, and felt the grasp of a hand on my neck--and there wasn't any
+hand there either."
+
+"A dead man?" repeated Ned.
+
+"Sure," Frank replied. "And he's not been dead very long, at that."
+
+Again the boy heard that vicious chuckle at the entrance. Then a voice
+came out of the mouldy darkness:
+
+"How are you getting on in the Secret Service, Ned Nestor?" the voice
+asked.
+
+"Finely!" Ned called back, but it seemed to him that his voice shook
+with the peril of the situation. He was known, his mission there was no
+secret, the enemies of the government were already on the ground, ready
+to combat him in his work. Just how far their hostility would extend was
+evidenced by the fall of rocks outside. It seemed to the boy that the
+struggle would be to the death.
+
+"Who are you talking to?" Frank asked.
+
+Ned did not reply to the question, for there came the sound of a scuffle
+outside, then a shot, a cry of pain, and the cavern was still as a
+grave.
+
+In the silence Frank's movements were heard, and Ned knew that he was
+backing out of the tunnel, with his light still burning. Entirely at a
+loss to account for the fracas outside, Ned awaited his approach with a
+fast-beating heart. When at last he shut off his electric searchlight
+and dropped from the tunnel through the old cupboard Ned seized his hand
+and drew him away.
+
+"Did you fire that shot?" Frank whispered.
+
+"No," was the reply. "There's fighting outside, and the shot was fired
+there. Now, I had a notion of sending a stream of bullets through the
+doorway, but the persons who are fighting the man who came upon us here
+may be our friends, so we must be careful what we do. Here. Take my
+flashlight. Open the two at the same instant and turn the rays on the
+doorway. I'll be ready with my gun."
+
+But before this movement could be carried out a voice the boys knew came
+out of the darkness.
+
+"Wonder you wouldn't give a fellow a lift," Jimmie said, in a panting
+tone. "I've got to the limit with this big stiff."
+
+The lights were on instantly, with Ned and Frank bounding toward the
+opening. The way was narrow, for many rocks had been dropped down from a
+broad ledge just above, but they managed to crawl through. But before
+Ned could reach the struggling pair on the floor the under figure
+wiggled away, staggered for an instant, and then made for the outer air
+at good speed.
+
+Jimmie sat upon the stone floor with a disgusted look on his freckled
+face.
+
+"Now see what you've been an' gone an' done!" he cried. "You've let me
+pirate get away! But he took a bullet with him," he added.
+
+"How many were here?" asked Ned, shutting off his light and telling
+Frank to do the same. "How many men did you see?"
+
+"Just that one," Jimmie replied, sorrowfully, "an' he got away!"
+
+Ned advanced to the entrance and listened. At first he heard the sound
+of limping footsteps, then the sweep of oars. He ran down to the beach
+and swept his light over the waters of the lake. A slender boat was
+speeding far to the north, and a solitary rower was bending to his work.
+
+Now, for the first time, Ned noted that a fierce gale was blowing from
+the west, and his thoughts went back to the plateau where the aeroplane
+lay exposed to the storm. He ran back to the cavern, barely escaping
+being blown off his feet on the way, and called to the boys.
+
+"There's a stiff wind blowing," he said, "and I'm afraid for the
+aeroplane. We must get back to the camp immediately."
+
+"The wind was on when I came in," Jimmie said, "an' it near blew me into
+the lake, even if I did hold on to the trees. We can never make the hill
+in the storm."
+
+"We've got to," Ned insisted.
+
+"Besides," Jimmie continued, "we want to find out about the dead man
+Frank has been telling me about. We can't take him with us, an' he will
+not be here when we come back. Whatever we learn about him, an' the
+cause of his death, must be learned now."
+
+"Sometimes, Jimmie," Frank burst out, "you exhibit signs of almost human
+intelligence!"
+
+"The boy is right," Ned observed. "I'm so rattled that I hardly know
+what I'm about. We ought to be in pursuit of that rascal who is rowing
+on the lake, we ought to be on the plateau, looking after the aeroplane,
+and we ought to be here, finding out if a murder has been committed."
+
+"It is a murder, all right," Frank said, "for the floor in the tunnel is
+sticky with blood."
+
+"I'm goin' in there!" Jimmie exclaimed.
+
+"Go if you want to," Frank grunted.
+
+Ned laid a hand on Jimmie's arm as he started away.
+
+"If you don't mind," he said, "I'd much rather you remained on guard.
+You have keen eyes, and may be of great service here."
+
+"All right!" the boy said. "I'll do anything you ask me to if you don't
+leave me out of the game."
+
+"No danger of your getting into the dust heap," Frank laughed. "How long
+have you been prowling about here?"
+
+"Just a short time," was the reply. "I remained in the tent until I
+thought Pat an' Jack were asleep an' then cut my lucky. Say, but the
+wind was blowin' when I slid down the slope toward the lake."
+
+"It must be fierce up on the plateau," Frank admitted. "Say," he added,
+turning to Ned, "if you don't mind, I'll go on up the hill and help the
+boys with the aeroplane. It would be a tragedy if it should be destroyed
+now."
+
+"All right," Ned said. "Get up there as soon as possible. The boys may
+be having trouble with the 'plane. And Jimmie," he added, "suppose you
+keep an eye on the plateau? The lads may signal."
+
+"Too dark for that," the boy replied, "but I'll keep a sharp lookout,
+just the same. Go on and look over the man Frank found under the
+mountain."
+
+Frank moved on up the hill, clinging to trees as he advanced, and
+stooping low, even then, to escape the force of the wind, while Jimmie
+stationed himself in the opening and looked out on the lake. Ned
+disappeared in the cavern, and the boy saw his torch grow fainter as he
+climbed through the narrow opening left in the rock which had been
+thrown over the natural doorway.
+
+It was getting late and the boy was sleepy, but he struggled manfully to
+keep his eyes open. Directly, however, he had no trouble in this regard,
+for he started up with a strange, acrid odor in his nostrils. The
+low-lying sky was aflame.
+
+

+CHAPTER VI.--ABOVE THE CLOUDS AT NIGHT.
+
+
+The wind gained strength as the heat of the forest fires increased. The
+roaring of the gale and the heavy undertone of the racing flames
+effectually drowned the voice of the forester, and it was only by the
+motion of his lips that the boys knew that he was trying to talk to
+them.
+
+Presently he threw his hands high above his head, weaponless, then
+lowered one and beckoned to them. Still keeping grasp on their
+revolvers, the boys approached him. His face was deadly pale, save for
+the glow of the fire which shone unnaturally on the wall behind him.
+
+"This is no time for accusations," he shouted. "We must do something to
+check the fire."
+
+"What is to be done?" Jack demanded, half won over by the apparent
+distress of the fellow.
+
+"The blaze will burn itself out against the mountains," was the reply,
+shouted at the top of the speaker's lungs, "but the fire in the canyon
+must be checked by going on ahead and felling trees."
+
+"Won't it burn itself out there, too?" asked Pat.
+
+"I'm afraid not," was the shrill reply. "There is an opening from the
+top of the canyon to a valley in a fold of the hills. The fire will do
+incalculable damage if it passes through that."
+
+"What do you suppose we can do against a fire like that?" demanded Pat.
+"An army could not stop the blaze now."
+
+"You are mistaken!" shrilled the other. "Three choppers can clear a
+space which the fire will not cross."
+
+"We'll get our axes and try," Jack said, reluctantly.
+
+"Then make haste!" Greer shouted. "At all events we must leave this
+place, for the fire will soon be here. Come!"
+
+When the boys turned to verify this statement they saw that the planes
+of the aeroplane were red with the reflection of the blaze below, and
+that the creeping fire was already showing at the lip of the plateau.
+
+"The aeroplane is doomed, I guess," wailed Jack, and Pat thought he saw
+a look of satisfaction in Greer's face as the words reached his ears.
+
+The smoke was now rolling over the plateau in great clouds, but through
+it Pat thought he saw figures moving from the south slope toward the
+aeroplane. Calling out to Jack, he sprang toward the machine, the
+suspicion in his mind that these were confederates of the alleged
+forester, and that the machine was, after all, the main point of attack.
+
+Greer saw the movement and darted toward the boy as if to block his way,
+but Pat struck out viciously and turned him back. Then a bit of flame
+sprang up in the cloud of smoke which was sweeping over the plateau. It
+seemed to Pat that an attempt to burn the machine in advance of the
+arrival of the forest fire was being made.
+
+When he darted forward again Greer caught him by the shoulder and hurled
+him away.
+
+"Get your axes!" he shouted. "There is no time to waste here."
+
+Then the smoke lifted for an instant and Pat saw three figures rise
+above the rim of the northern slope and hasten toward the aeroplane.
+Their arrival there was followed by shots and calls for assistance. Then
+the smoke shut down again, and the roaring of the flames drowned all
+other sounds.
+
+Greer stood for an instant, braced against the wind, shielding his face
+from the hot blasts scorching the grass of the plateau, then turned and
+ran. Then both boys heard a call from the direction of the machine.
+
+"The way is clear to the cavern!" were the words they heard. "Remain
+there until we return!"
+
+"That's Ned," shouted Pat. "Just in time to save the aeroplane."
+
+Almost before the words were out of his mouth there came a lull in the
+wind and the great machine ran forward a few yards, then swung into the
+air. At that moment Frank came running toward the two astonished boys.
+
+"We've got to leg it!" Frank shouted, his mouth close to Jack's ear.
+"Drop low on the ground so as to get fresh air and run!"
+
+Jack, although he had heard Ned's voice giving directions, and although
+he knew that Frank was by his side, could hardly sense the situation, or
+all that had taken place. The action had been so swift that he could not
+yet realize that Ned had snatched the aeroplane away from certain
+destruction and lifted it into the stormy sky in so short a time.
+
+However, he did not stop then to place the events in neat order in his
+mind, for the fire was working across the scant vegetation of the
+plateau and the air was hot and stifling. It was all like a page out of
+the Arabian Nights, but he put the wonder of it away, grasped Frank's
+hand, and, crouching, ran toward the incline leading to the lake. There
+was safety there, at least.
+
+Now and then, in their swift flight, the boys stopped and looked upward,
+hoping to learn something of the fate of the aeroplane, but the great
+machine was not in sight.
+
+"Ned never can make it live in this gale!" Jack almost sobbed, when, at
+last, they all came to a halt at the margin of the lake. "The whole
+shebang will go to pieces and the boys will be killed."
+
+"Aw, forget it!" grunted Pat. "I'm not in love with airships, but I know
+that Ned wouldn't have gone up unless he knew that he could handle the
+machine. He'll lift above the divide and drive straight before the wind.
+The good Lord only knows how far the gale will take him, but I'm betting
+my head against turnips that he'll come back by morning, asking why
+breakfast isn't ready!"
+
+"How did you get wise to the trouble up here?" Jack asked of Frank.
+
+"Why, I don't exactly know," the boy replied. "Ned sent me on ahead to
+look out for the aeroplane. He said he wanted to remain in the cavern
+and investigate. I was making slow progress up the hill when Ned and
+Jimmie came running after me. I had noticed long before that the sky
+looked like fires were burning somewhere."
+
+"I should say so," Pat cut in. "The clouds looked like they had been
+soaked in red paint."
+
+"When Ned came up to me, running like a racehorse," Frank went on, "he
+said he was going to take the aeroplane out, wind or no wind. I didn't
+have much chance to talk with him, but I understood that he was going to
+do just what Pat has suggested--run before the wind and swing back
+whenever he could."
+
+"I presume Jimmie is good and scared by this time!" Jack commented.
+
+"When we got to the machine," Frank went on, "we found two men there
+with some sort of torches in their hands, trying to set the machine on
+fire. We caught them unawares and left them lying there. I hope they
+didn't get burned to death."
+
+There was a short cessation of speech while the boys listened to the
+roaring of the flames and watched the fire mounting into the sky. It was
+a wild scene--one calculated to bring terror to the breast of any human
+being. The wind was dying down a little, but the clouds were still
+driving fast before it, their edges tinged with flame so that they
+resembled golden masses floating across an eternity of space clothed in
+smoke.
+
+While the boys watched the great display Frank pointed to a wall of
+flame rounding the corner of the plateau.
+
+"The fire will burn this slope," he said, "and we've either got to get
+into the cave or out on the lake. Which shall It be?"
+
+"The cave for mine!" Jack cried.
+
+"And mine," echoed Pat. "Who knows what the fire will do to the lake?"
+
+But Frank had had previous experience in the cavern. He was thinking of
+the still figure he had found lying there, and of the dark stains on the
+floor.
+
+"If we could find a boat," he said, without mentioning his real reason
+for objecting to the cave, "we might get along very well on the lake. We
+don't know what stifling air we shall find in the cave, and, besides,
+the men we have just had a fracas with may return at any time. It
+wouldn't be nice to be locked up in that hole in the ground."
+
+The wind was dying down to a steady breeze, and the fires seemed to burn
+lower. The clouds above were dark and threatening, save where gilded by
+the reflection from below, and seemed to be massing. Frank held up a
+hand and shouted.
+
+"Rain!" he cried. "Rain!"
+
+It was no gentle spring shower that opened upon the earth then. The
+fountains of the great deep seemed to have opened wide. The water fell
+in sheets, and in an instant the boys were wet to the skin.
+
+"Better than fire!" Jack suggested.
+
+The rain pelted down upon the forest fires viciously, and the hissing
+protests of the angry embers rose in the air. Through the thick veil of
+the rain clouds of steam could be seen rolling over the lake and along
+the threatened incline. In ten minutes water was pouring down the steep
+hill in sheets and the fires were leaping no more.
+
+Pleased as the boys were at the opportune arrival of the rain-bearing
+clouds, they could not help wondering if the freak of chance which had
+preserved the forests of northern Montana had not brought Ned and Jimmie
+sudden death.
+
+"They never can handle the machine in such an air-ocean," Jack declared,
+but the more optimistic Pat asserted that Ned must have been a mile
+above the rain clouds before a drop of water fell.
+
+"I guess the fire brought this rain on," Frank said, wiggling about in
+his wet garments, "but it's just as wet as if brought about by some
+other means. What are we going to do now?"
+
+"Why not go to the cave until the rain stops?" asked Pat.
+
+"It is colder in there than it is here," Frank said, still thinking of
+the silent figure in the narrow tunnel back of the cupboard.
+
+"We can't get any more water in our clothes and hides than we have now,"
+Jack observed, "so we may as well stay outside and watch for Ned and the
+aeroplane. I don't believe any other person ever took an aeroplane up in
+such a storm. I'm afraid Ned was smashed against the divide."
+
+"Ned's all right," insisted Frank. "Suppose we go back to the plateau
+and see if there's anything left of our tents."
+
+"I'm game for that," Pat said, "but," he added, turning a keen gaze on
+Frank, "I'd like to know why you object to going to the cave. Jack and I
+would like to see it."
+
+"Well," Frank replied, not without some hesitation at bringing the scene
+in the tunnel back to his mind in form for expression in words, "there's
+a crime been committed in the cave, and it's uncanny."
+
+"A crime!" repeated Pat, all excitement at the suggestion of another
+adventure, "what kind of a crime?"
+
+"A murder," replied Frank, with a shiver.
+
+"Let's go in and see," Pat said.
+
+"Frank's afraid," Jack put in.
+
+"Of course I'm afraid," Frank admitted. "You go in there, and crawl on
+your knees through the thick air of a narrow tunnel, and put your hand
+on a dead man's face, and feel your other hand slipping in the blood on
+the floor, and you'll be afraid, too. I'm not going back there."
+
+"We can stand here in the rain all night, if you want to," Pat said,
+with scorn in his voice. "Rainwater is said to be good for the
+complexion."
+
+The wind was slowing down and the rainfall was not so heavy as before.
+The boys, Pat and Jack, joking Frank about his terror for the cave, and
+Frank just a little angry, began the ascent of the slope leading to the
+plateau.
+
+"The rain saved the trees next to the mountain," Pat said, presently,
+"and if it checked the fire on the plateau at the same line our tents
+are all right. Say," he added, "who ever heard of such a downpour as
+that. I reckon the rain swept in from the ocean in heavy clouds which
+were broken open by the mountains."
+
+"Much you know about it!" laughed Jack. "You talk as if you could cut a
+cloud with a knife."
+
+"Anyway," persisted Pat, "the water tumbled out and checked the fires.
+Wonder what became of the man who said his name was Greer? He was
+standing in with the men who were trying to burn the aeroplane, all
+right enough, and I believe the whole circus was started just to destroy
+the airship and bring Ned's investigations to a close."
+
+"We always do get into the thick of it at the first jump," Frank said,
+remembering the bomb under the cottage in the Canal Zone and the raid on
+the nipa hut in the Philippines. "Whenever we've got anything coming to
+us, we get it by lightning express."
+
+"You bet we do!" Jack exclaimed. "Now we're getting a clear sky," he
+added, pointing upward, "and we're getting it short order time, too!"
+
+The heavy clouds were gone, the moon was smiling down on the drenched
+earth, the stars were winking significantly toward a spot on the plateau
+where two unrecognizable figures, half burned away, were lying. When the
+boys reached the top of the climb and advanced to the spot where the
+aeroplane had stood they turned sick with the horror of the thing.
+
+"I almost wish we had let them destroy the aeroplane," sighed Frank. "I
+don't like to think that these men came to their death through us. It is
+awful!"
+
+"Did you shoot them?" asked Pat.
+
+Frank shook his head.
+
+"They shot at us," he said. "They fired as soon as we got to the rim of
+the dip, but missed because of the smoke and the wind. Then we rushed
+them, and they went down--to escape punishment, I thought--and so Ned
+got the aeroplane away."
+
+"Then you had nothing to do with their death," consoled Pat. "They came
+here to commit a crime and were overcome by the smoke and heat."
+
+Frank would gladly have accepted this version of what had taken place,
+but he could not bring his mind to do so at once. The horror of what he
+had found in the cave was still upon him.
+
+Leaving the spot where what remained of the outlaws lay, the boys
+hastened to the wall of rock which terminated the plateau on the east.
+The rain had indeed saved the tents from destruction. The canvas was
+huddled against the wall, stained with smoke and heavy with rain, but in
+fairly good condition.
+
+"We'll have to remain here, or about here, until Ned comes," Pat said,
+"so we may as well put the tents up. I wonder if it isn't most morning?"
+
+"Does that mean that you are getting hungry?" grinned Jack.
+
+"You bet it does!" was the reply. "Anyway, I'm going to see if I can
+find dry wood enough for a fire. If I can I'll make some hot coffee. Ned
+will see the fire, and know we are not in the cave."
+
+Then an exclamation from Frank called the speaker's attention to the
+clear sky over the divide. The upper strata of clouds were drifting
+westward on a high current of air--what few clouds there were--and far
+up in the blue, the moonlight trimming the planes with silver, rode the
+aeroplane, seemingly intact, and working back on the high current toward
+the Pacific coast.
+
+
+
+
+CHAPTER VII.--A KEY WITH A BROKEN STEM.
+
+
+The lights were burning low in a bachelor flat on a noisy street corner
+in the city of San Francisco, and a man of perhaps thirty lay on a couch
+with his eyes closed. There were in this sitting room, which faced one
+of the noisy streets, a grand piano, a costly music cabinet, a walnut
+bookcase filled with expensively bound volumes, numerous lazy chairs of
+leather, and the rug on the polished floor was rich and soft. The
+occupant of the flat evidently enjoyed luxurious things and had the
+money to pay for them.
+
+When a clock in a distant steeple struck midnight there came a knock at
+the locked door in the main corridor which connected with the private
+hallway on which the flat opened. A Japanese servant, small, obsequious,
+keen-eyed, opened the door, after the hesitation of a moment, and peeked
+out. He would have closed it again instantly, seeing a stranger there,
+only Ned Nestor, who had anticipated some action of the kind, thrust a
+shoe into the opening, and, reaching in, unfastened the chain.
+
+"I wish to see Mr. Albert Lemon," he said.
+
+The Jap tried to force the door back and lock it, but was unsuccessful.
+
+"No savvy!" he cried, as Ned brushed past him and stood in the private
+hall.
+
+Ned paid no further attention to him, but entered the sitting room and
+at once advanced to the couch where the man lay. The figure on the couch
+did not move, but the Jap forced himself in the boy's way with his cry
+of "no savvy!"
+
+"Opium?" Ned asked, pointing down to the man.
+
+"No savvy!"
+
+"Hit the pipe?" he asked, putting the question in a new way.
+
+"No savvy! No savvy!"
+
+"Dope, then?" Ned went on. "Tell me if this man has been doping himself
+into unconsciousness. Dope, eh?"
+
+Ned lifted his voice, half hoping that the man on the couch would show
+some signs of life, but there was no movement of the eyelids.
+
+"No savvy!" grunted the Jap.
+
+Ned took the servant by his shoulders, pushed him gently out of the
+room, and closed and locked the door, the key being in the lock on the
+inside.
+
+"No savvy! No savvy!"
+
+The words came through the thin panel of the door in quick succession
+for a minute and then silence. Again Ned advanced to the side of the
+couch and looked down upon the semi-unconscious man.
+
+It was clear to the boy that the fellow sensed what was taking place,
+but was too well satisfied with the drugged condition in which he lay to
+disturb his poise of mind by taking note of anything whatever. The
+figure of the fellow was dressed in expensive clothes of latest cut, but
+they were soiled, and even torn in places.
+
+The disreputable condition of the garments reminded Ned of a suit in
+which he had once been hauled through a briar patch and pulled into a
+pond at the hands, or horns, rather, of a village cow, assisted by a
+rope. His clothes, it is true, had not been expensive ones at the time
+of the occurrence, but the looks of the clothes the drugged man wore
+reminded him of the damage his cheaper ones had sustained.
+
+The face of the man on the couch was deadly pale, with the drawn look
+about the skin which comes of much familiarity with the drug made of the
+poppy. It was still an attractive face, even in its degradation, and the
+forehead was that of a capable man.
+
+Ned drew a chair to the side of the couch and sat down. Even if he
+should at that time succeed in attracting the attention of the man, the
+fellow was in no condition to answer the important questions he was
+there to ask.
+
+Presently the Jap, or some one else, came and rapped lightly on the
+door, and Ned opened it a trifle and looked out.
+
+"No savvy!" cried the Jap, repeating the words like a parrot, standing
+in the hall with many signs of fright on his yellow face.
+
+"All right!" Ned said, shutting the door in his face, "you don't have
+to."
+
+"I can't blame him for thinking this a cheeky invasion," Ned smiled, as
+he returned to his chair at the side of the couch. "It isn't exactly the
+thing to walk into a man's private room in this manner."
+
+Ned had decided to sit by the side of the half conscious man until he
+returned to his full mentality. Questions now might produce only pipe
+dreams, for the imagination is rather too active under such
+circumstances.
+
+Five days before Ned had left the boys in a cup on the western slope of
+the Rocky Mountains, not far from the summit, after explaining to them
+that he was going to the city to investigate a clue connected with the
+murder of the man who had been found in the cavern. Leaving the
+aeroplane safely hidden at Missoula, he had traveled by rail to San
+Francisco.
+
+In his handbag on this trip were two seemingly unimportant articles--a
+piece of tape cut from the inner side of the collar of the dead man's
+coat, and a small, odd-shaped key with the stem broken off so that it
+was only about an inch in length. The key had been the only article
+found in the dead man's pockets. The strip of tape bore the name of a
+San Francisco tailor.
+
+The directory had assisted him in finding the tailor, and the tailor had
+informed him that the coat had been made for one Albert Lemon, whose
+address he gave. So here he was, in Lemon's apartment, seeking
+information concerning the dead man, while Lemon, supposedly Lemon, lay
+in an opium daze on the couch.
+
+But Ned's time, waiting for the man to come back to consciousness, was
+not all wasted. Moving carefully about the room, he found that the
+broken key fitted a writing desk which stood between two windows. The
+lock which it fitted, however, was not in good condition, for the bolt
+had been pried back, damaging the polished edge of the casing which held
+the socket. The desk contained nothing of importance, and Ned left it as
+he found it.
+
+Sitting there in the soft light of the room, he did not know whether the
+man on the couch was Albert Lemon or whether the man who had died in the
+cavern was Albert Lemon. He believed, however, that the outlaws he had
+encountered in the mountains, had murdered the man, and felt that the
+surest way to trace the crime to them was to find out why the man had
+joined them--why he was there in the tunnel back of the cupboard. This
+would be likely to bring out a motive for the deed.
+
+He did not, of course, know whether the dead man had stood as an enemy
+to the outlaws, or whether he had stood as a friend. But that could make
+no difference with the quest he was on. He believed that the outlaws
+were the men he had been instructed to hunt down, and knew that proof
+could be obtained only by an intimate knowledge of their associations,
+their ways, their motives. The friends of the dead man he thought, would
+know something about them, perhaps be able to place them in the circle
+in which they lived when not in the hills.
+
+In work of this kind it is the first task of an investigator to "place"
+the man he is pursuing. The burglar is as good as taken when he is
+traced back to those he associates with in his hours of leisure. In the
+absence of a clue pointing to a person, the investigator busies himself
+in finding a motive. Ned believed that he now had the personal clue. The
+motive would place the proof in his hands.
+
+So his Secret Service work for the government was leading him into the
+investigation of a murder mystery. He smiled as he held up the key and
+wondered if the facts when discovered would bear out the suspicions in
+his mind. Again he asked himself the question:
+
+"Is this Albert Lemon, or was the dead man Albert Lemon?"
+
+After a long time the man on the couch opened his eyes and looked about
+the room. His glance rested for an instant on the figure in the chair at
+his side, but the fact of its being there did not appear to surprise him
+in the least.
+
+"Jap!" he called faintly.
+
+There was a sound at the door, but it was still locked, and the servant
+was unable to obey the summons.
+
+"Bring me a pipe!" were the next words.
+
+The Jap clamored at the door, but did not gain admission. The racket
+seemed to disturb the man not at all.
+
+"I think," Ned said, "that you have had all the dope you need to-night.
+Besides, I want you to answer a few questions."
+
+"Perhaps I have," the man said, "but, supposing that to be the case,
+where do you come in? You are a new one on me, and I hope you won't flop
+out of a window or go up through the roof, as some of the others have
+done. I want to have congenial company to-night. Who are you?"
+
+"Ned Nestor," was the quiet reply.
+
+"So," said the man on the couch. "I've heard of you--read about you and
+the Canal Zone in the newspapers. But you're only a kid. What about
+that?"
+
+"I can't help being young," laughed Ned. "Anyway, that is a fault I'll
+soon get over. We all have it at first."
+
+"And get over it too quickly," said the other, with a sigh. "Well, what
+do you want here?"
+
+"Are you Albert Lemon?" asked Ned abruptly.
+
+"Yes," was the reply, "I'm Albert Lemon. What about it?"
+
+The man was gaining mental strength every moment now, and seemed to
+sense the strange situation.
+
+"Stiles is your tailor?" the boy went on.
+
+"Look here," said the other, rising to a sitting position and passing a
+shaking hand across his brow, as if to brush away the fancies of the
+poppy, "when you convince me that you have a laudable interest in my
+personal affairs I'll be glad to answer your questions."
+
+Ned took the strip of tape from his pocket and held it out to the man on
+the couch.
+
+"Do you recognize that?" he asked.
+
+Lemon nodded coolly, but a look of wonder and alarm was growing in his
+bloodshot eyes, and his jaw dropped a trifle.
+
+"I still lack the proof of laudable interest," he said, with a twisting
+of the face intended for a smile.
+
+"Answer the question," Ned replied, "and I'll inform you of my interest
+in this article--and in you."
+
+"Yes, I recognize it as the private mark of Stiles, my tailor," Lemon
+answered, in a moment. "Where did you get it? If you insist on asking
+personal questions I must insist on the right to do the same thing."
+
+"I cut this private mark," Ned said, "from the collar of a coat found on
+the back of a dead man in Montana, somewhere near the main divide of the
+Rocky Mountains. Do you know how it came there?"
+
+"Yes and no," was the reply.
+
+"Kindly answer the affirmative proposition first," Ned said, with a
+smile.
+
+"Well," said the other, "about three months ago an old college friend of
+mine, one Felix Emory, came to me from Boston. He was in bad with his
+people, and was out of money. I took him in here and tried to brace him
+up. I couldn't do it. His moral stamina was gone."
+
+Lemon paused a moment, and, with a deprecatory smile, pointed to an
+opium pipe which lay on the rug near the couch.
+
+"I understand," Ned said.
+
+"I fed him, and clothed him, and introduced him at the club, and gave
+him every chance in the world to get a brace, but he fought me off. All
+he cared for was a pipe and a pill and a place to sleep it off."
+
+"And so you gave him up as a bad proposition?" asked Ned.
+
+"Not exactly. He wanted to go to the mountains on a hunting trip. Well,
+I thought it would benefit his health, so I rigged up an outfit for his
+use and let him go. You say the man was dead?"
+
+"Quite dead," Ned replied.
+
+"Too much poppy, I presume?" Lemon asked with an ashamed smile.
+
+"Too much steel," Ned answered, sharply.
+
+Lemon stared at the boy for an instant, his eyes more anxious than ever,
+and arose shakingly to his feet.
+
+"Do you mean that he was murdered?" he asked.
+
+Ned nodded.
+
+"Where?" was the next question.
+
+"I found the body in a cavern on the western slope of the Rockies," was
+the reply. "He had been dead only a few hours."
+
+Albert Lemon maintained a thoughtful silence for a time, during which
+Ned eyed his changing expression keenly.
+
+"And what do you wish me to do about it?" he then asked.
+
+"A crime has been committed," Ned replied, "and it seems to me that you
+ought to do all in your power to assist in bringing the criminal to
+punishment."
+
+"Granted, sir. Tell me what to do."
+
+"First, tell me about the men your friend went away with."
+
+"That brings me to the negative proposition," the other answered. "I
+have told you how Felix came by my coat, but I can't tell you whether
+the man the coat was found on was Felix. You must see that for yourself.
+He might have given the garment away, or he might have sold it in the
+city to get money for opium. In short, the coat might have been on the
+body of a man I never saw."
+
+"Then you can't tell me who Emory went away with?" asked Ned.
+
+"Certainly not," was the reply. "I don't know whether he went away at
+all or not."
+
+This was disappointing, but Ned had one more lever with which the man's
+indifference might be lifted, he thought. Before speaking again Lemon
+arose and turned the key in the lock of the door, against which the
+servant was still pounding. The Jap entered and stood by the door,
+looking intently at Ned.
+
+"When you gave him the suit of clothes he went away in," the boy went
+on, shifting his position so that both men would be under his eyes,
+"what articles, if any, remained in the pockets?"
+
+"Not a thing," was the reply. "I looked out for that."
+
+"Then anything discovered in the pockets of the dead man," Ned said,
+taking the key from his pocket and toying carelessly with it, "must have
+belonged to him?"
+
+Ned saw Lemon give a quick start at sight of the key. The Jap advanced a
+step as if to get a closer view of it. Then both men turned their eyes
+for an instant to the broken lock of the writing desk. Ned had gained
+his point. The men recognized the key.
+
+"Where is the body you speak of?" Lemon asked, presently.
+
+"Buried near the cavern in the mountains," was the reply.
+
+"Perhaps you can give me a description of the body," Lemon said. "I
+might be able to say, then, whether the man was Felix."
+
+"Look in the mirror," Ned replied, "and you will see there a fairly good
+representation of the dead man. About the same in height, in size, and,
+yes, in feature."
+
+"Then it must have been Felix," the other said. "His remarkable
+resemblance to myself has often been remarked. Poor fellow! I'm sorry
+that his end should come in so ghastly a form."
+
+There was a short silence, during which Lemon's eyes flitted from the
+key in Ned's fingers to the writing desk.
+
+"I said a moment ago," he observed then, "that I searched the pockets of
+the clothes before I gave them to him, or words to that effect. I
+remember now that I ordered Jap to do it. Did you obey orders?" he
+asked, turning to the servant.
+
+Ned saw the Jap give a quick start, then regain control of himself.
+Lemon, too, looked crestfallen for a moment, then addressed the Jap in
+another tongue.
+
+"I was talking in English," he said, "and forgot for the moment that he
+would not understand me."
+
+There followed a short conversation between the two, and then Lemon
+announced that the Jap had forgotten to look in the pockets of the
+clothes. Ned ignored the explanation and put the key in his pocket. He
+knew now that the Jap could understand English, and also that the key
+belonged to Albert Lemon, alive or dead.
+
+[Illustration: ILLUSTRATION No. 3]
+
+Lemon arose and, going to a table, secured a tobacco pouch and a book of
+cigaret papers. As he rolled a cigaret Ned observed that the middle
+finger of his left hand carried, just below the nail, a blue spot, as if
+he had been using a typewriter since cleaning his hands. Ned noticed it
+particularly, as he himself used a double keyboard machine and usually
+smutted that finger on the ribbon when he rolled the platen.
+
+"Well," Lemon said, "I'll have to ask you to excuse me now. I've been
+off on a long country tramp. You see how mussed up I am. I think I
+crawled through briar patches and wire fences and fell into cow ponds."
+
+Ned turned away without a word, with plenty of food for thought in his
+mind.
+
+
+
+
+CHAPTER VIII.--FATE OF THE STEAK A LA BRIGAND.
+
+
+Jimmie lay stretched at full length under one of the discolored shelter
+tents in a little cup in the heart of the Rocky Mountains. Frank and Pat
+and Jack were moving restlessly about, looking up at the blue sky
+expectantly. Ned had not returned from his trip to San Francisco, and
+the boys were anxious as to his safety.
+
+"He should have taken me with him," Jimmie drawled, presently, when
+Frank threw himself down by the tent. "Then he'd have been all right."
+
+"It is a wonder that he got along in the world at all before he fell
+under your protecting care," Frank replied, with a grin.
+
+"Oh, he managed in some way," Jimmie answered, "but he never got up in
+the world until he took me into partnership," with a wink at his chum.
+
+"He's been up in the world since then, all right," Frank said,
+suggestively.
+
+"Too high up," Jimmie grinned. "Too high up for me, anyway. I thought
+I'd die up there, on the night of the fire."
+
+"In all the history of air navigation," Frank observed, soberly, "there
+was never a trip like that. When I think of the quick start, and the
+wind and the rain, the whole thing seems like a dream. How did he ever
+do it?"
+
+"I don't know," Jimmie replied. "He boosted me into the seat, and the
+next I knew we were off, an' the fire was dropping away from us, an' the
+mountains were growing smaller, an' the peaks looked like warts on the
+world. I felt like I was fallin' over the edge of somethin'."
+
+"And the wind?" questioned Frank. "Didn't it take your breath away?"
+
+"Wind, nothin'," the boy said, scornfully. "There wasn't any wind where
+we were. We went along with it. It was like sailin' on a swift stream.
+Ned tuned the engine up to keep steerway, an' shut his teeth. Then, in
+half a minute, we were above the clouds, an' the moon an' stars were
+askin' what we were doin' up there."
+
+"You're saying it well," Pat said, joining the little group. "If you
+were going so merrily before the wind, why did he want steerway?"
+
+"You don't know much about the atmosphere," laughed Frank, answering for
+Jimmie. "If you did, you'd know that the air blanket of the earth is a
+good deal like a river. It has eddies, and currents, and ripples, and
+holes, too."
+
+"You're good, too!" exclaimed Pat. "Holes in the air is about the best I
+ever heard!"
+
+"Of course there are holes in the air," Frank replied, with the air of
+one imparting valuable information, "especially when there are fires
+beneath. And, let me tell you this, you old red-head," he added, with an
+exasperating grin, "when the air, driven swiftly by the wind, or what we
+call the wind, comes to mountain peaks, and tall trees, and
+sky-scrapers, it just backs up, just the same as water does when it
+comes to a dam, or any obstruction."
+
+"Go it!" Pat cried. "Make it a good one! Where does this air go when it
+backs up?"
+
+"It just hunches up," Frank replied, gravely, "and checks the flow back
+of it, and then eddies and swirls away, fit to twist an aeroplane into
+kindling wood."
+
+"Of course," broke in Jimmie. "I've often read of aeroplanes dropping a
+thousand feet into holes in the air, and of their being swept against
+tall trees and buildings by eddies. It takes a cool head to run an air
+machine in a storm of wind, and that is where Ned won out."
+
+"If he hadn't kept the aeroplane going with the wind at full speed,"
+Frank added, "he would have been in a wreck the first half mile."
+
+"The more I learn about the atmosphere," Pat said, "the less I like it.
+When you get me up in an aeroplane, just send word to the folks that I'm
+tired of life."
+
+"Ned ought to have a Carnegie medal for what he did that night," Jack
+remarked, "and I'm going to speak to father about it when I get home."
+
+"There is no doubt that he ought to have one," Frank said, "but the men
+who really deserve Carnegie medals never get them."
+
+"You're an anarchist!" roared Pat.
+
+"All right," was the sober reply, "but if I had the giving out of the
+medals I'd present them to men who work twelve hours a day and provide
+for families of eight on nine dollars a week--the men who never get
+rested, and who never have enough to eat. They are the ones who ought to
+have the medals."
+
+"Most of them would sell the medals," Jack said, cynically.
+
+"Well," Frank replied, "I shouldn't blame them if they did. I'd rather
+have a porterhouse steak in the interior than a piece of bronze on the
+outside."
+
+"Don't talk about porterhouse steak!" pleaded Jimmie.
+
+"Hungry, little man?" asked Pat.
+
+"Hungry! I'm like one of the men Frank has been telling about. I never
+get rested, never have enough to eat."
+
+The boys fell upon Jimmie and rolled him out of the tent.
+
+"You get busy with fuel," Pat said, after they had given him plenty of
+"movements," "and I'll cook a steak a la brigand."
+
+"We ain't got no steak," complained Jimmie.
+
+"We've got potatoes, and bacon, and onions," Pat said, "and canned
+beefsteak. You just watch me. I used to cook steak a la brigand in the
+Philippines."
+
+"Get busy, then," Jimmie said, "and Jack will help get the green wood."
+
+"If you bring green wood here for me to cook with, I'll roast you over
+it," Pat said. "You get a lot of good dry wood that will make coals, and
+I'll show you how to broil a steak a la brigand."
+
+"Why do you call it a brigand steak?" asked Jimmie.
+
+"Because it takes a red-headed brigand to cook it," suggested Jack,
+dodging out of Pat's reach.
+
+"Never you mind the name," Pat replied. "Get the dry wood and I'll broil
+a steak that will melt in the mouth."
+
+"That old canned stuff?" asked Frank.
+
+"Get the wood," ordered Pat, "and I'll show you."
+
+There were a few dead trees--the sole reminders of a former forest fire
+in that green valley--close at hand, and the wood was soon gathered and
+placed in a great pile near two rocks which Pat had rolled to within a
+yard of each other.
+
+"Here!" Jack called out, as Pat transferred the whole supply to the
+space between the stones, "there's enough fuel there for a week's
+cooking. Quit it!"
+
+"My son," Pat replied, with a provoking air of patronage, "what you
+don't know about broiling a steak a la brigand would make a
+congressional library."
+
+While the wood was burning down to coals, Pat cut a green slip about an
+inch in diameter at the bottom and peeled and smoothed it nicely.
+
+"Is that to be used to enforce the eating of the steak?" asked Frank,
+winking at the others.
+
+"To keep you from gorging yourselves," Pat replied, going on with his
+work.
+
+In a short time he had the potatoes cut into half-inch slices. Jack had
+peeled them and, following directions with many grins, had also cut a
+round hole an inch in size in the middle of each slice.
+
+"He's going to wear 'em around his neck, like beads," Jimmie suggested,
+looking carefully over the heaped-up dish.
+
+The bacon was now sliced thin, as were the onions, and in the center of
+each slice a round hole was made. Then Pat opened a couple of tins of
+beefsteak--so called by the packers--and cut a hole in the middle of
+each slice. Then he strung a slice of potato on the spit, then a slice
+of bacon, then a slice of onion, then a slice of beef, until there was
+nearly a yard of provisions.
+
+"I begin to feel hungrier than ever!"
+
+Jimmie was dancing around the fire as Pat turned the spit. There were
+only coals now, and Pat kept the toothsome collection turning slowly, so
+as to broil without scorching. The smell of the cooking bacon and onions
+set the boys to getting out the tin plates and making the coffee.
+
+The sun, which had been shining fiercely all day, now seemed to be
+working his way through a mist. The atmosphere appeared to be tinted
+with the yellow haze one sees in the northern states in autumn.
+
+As the boys were keeping watch for Ned and the aeroplane, they noticed
+the change in atmospheric conditions, but attributed it to the rising
+vapor brought out by the heat of the sun.
+
+"Say," Jimmie said, presently, "I smell smoke. I wonder if there's goin'
+to be another forest blaze here?"
+
+"Of course you smell smoke," Jack said, watching the broiling supper.
+"We're cooking a steak a la brigand, ain't we?"
+
+"Smells like burnin' leaves," Jimmie insisted.
+
+"More like onions," Pat observed.
+
+The boys crouched about the fire for some moments longer and then Jimmie
+arose and began to climb the wall of the cup to the west.
+
+"I'm goin' to see about this," he said.
+
+Frank laid a hand on his arm.
+
+"You wait a minute," he said. "You can't climb that slope in less than
+half an hour, and Ned will be here before that. Look! He's coming now,
+like the wind!"
+
+The aeroplane, high up in the hazy sky, was indeed making good progress
+toward the little cup in the mountain side. While the boys looked they
+saw it shift away to the west, whirl back to the east, dart off to the
+north and back again.
+
+"He's huntin' for us," Jimmie said.
+
+"He's investigating!" Frank cut in.
+
+"Investigating what?" Pat demanded. "He's smelling of this steak a la
+brigand and is hunting for it. Let be. He'll find us."
+
+The sky was growing more uncertain every minute, and puffs of smoke were
+seen out in the west, over the rim of the cup.
+
+"The world is on fire, I tell you!" Jimmie cried, presently. "That's
+what Ned is shiftin' about for. If the blaze wasn't high up on the
+mountains we couldn't see the columns of smoke over the rim of the
+valley."
+
+"Well," Pat observed, "the fire can't get in here. Nothing to burn."
+
+"It can fill the cup with hot air and scorch us to death," Frank said,
+uneasily. "I think we'd better be looking about for a place to crawl
+into."
+
+"Wait until Ned comes," Jimmie suggested. "He'll know what to do."
+
+The aeroplane acted badly in the currents caused by the burning forest,
+but Ned finally managed to bring it down in the valley. The boys
+gathered about him, all excitement, and the steak a la brigand was for
+the moment forgotten in the joy at the return of the patrol leader and
+the anxiety to learn something of conditions out in the woods.
+
+"It's going to be a great conflagration," Ned said, "but I think the
+aeroplane will be safe here. The whole slope is on fire."
+
+"I wouldn't take chances on leaving it here," Frank advised. "I'd jump
+over the divide with it."
+
+"I have been in the air three hours now," Ned replied, "and must have a
+rest. Besides, we must remain where we can, if necessary, help head off
+the flames. That is what we are here for, remember."
+
+"Not to fight fires," corrected Frank, "but to find out who sets them."
+
+"Anyhow," Ned replied, "we must fight the fire, if it gives us a chance,
+now that we are here. Now, what do you think that is?" he added, as a
+chorus of howls and cries came up from the slope on the west.
+
+"Sounds like a country circus!" Jimmie laughed.
+
+"That is just what it is!" Ned exclaimed. "Here! Help me roll the
+aeroplane into that nook, where it won't be trampled into splinters. Now
+you boys get behind it, and I'll get in front. Whatever you see or hear,
+don't shoot unless you are actually attacked."
+
+The boys obeyed the commands without a word of comment, well knowing
+what was coming next. A breeze was sliding up the slope, bringing with
+it flying masses of smoke. Presently birds began to stagger through the
+heavy atmosphere, flying low, almost within reaching distance, as they
+had fled long before the mounting flames and were exhausted.
+
+"I wish this would let up a moment," Pat said, "long enough for us to
+reach that steak a la brigand. It must be about done by this time."
+
+"I'll go an' get it," volunteered Jimmie. "An' eat most of it on the way
+back."
+
+"Then bring the coffee," cried Jack.
+
+"Why can't we all go out there and eat?" asked Frank.
+
+The boys were about starting with a rush when Ned caught two of them by
+the arm and stopped the others by a quick call. Through the smoke and
+the hot air on the rim of the cup, a great head, a head neither white
+nor black, but grizzly, was seen. Then a deer bounded over and crouched
+down in the valley. Next two mountain lions raced over the lip of the
+valley and halted growling, within a few yards of the boys.
+
+"There goes our steak a la brigand!" Jimmie cried, as the rush of
+frightened animals showed under the smoke. "I'll eat one of them deer to
+pay for this," he added.
+
+"You'll be lucky if one of these wild animals doesn't eat you," Jack
+said. "How would you like to be back in little old Washington Square
+just now?"
+
+"Forget it!" was the boy's only reply.
+
+"Will the fire get here?" Frank asked of Ned, as the wild creatures of
+the forest poured into the valley, regardless of the presence of the
+boys, unmindful of the proximity of each other.
+
+"I don't think the flames will come into the cup," Ned replied, "but if
+the smoke settles here we shall have a hot time of it."
+
+"Huh!" Jimmie cried. "The whole valley is full of mountain lions, an'
+bears, an' deer, an' snakes, an' rabbits. There ain't no room for any
+smoke!"
+
+Then the smoke rolled away for an instant, showing a sun as red as a
+piece of molten iron; showing, too, a huddle of forest animals crowding
+together in the center of the valley. In their terror of the fire they
+had forgotten to be afraid of mankind--of each other!
+
+
+
+
+CHAPTER IX.--THE CHAOS OF A BURNING WORLD.
+
+
+That was a day long to be remembered in the Great Northwest. It is true
+that the destruction of life and property at that time by no means
+equaled the ruin wrought by the forest fires of August, 1910, but the
+conflagration was serious in its final results for all that.
+
+In August of the previous year half a hundred persons lost their lives
+in the fierce fires which swept over portions of Idaho and Montana, and
+more than six billion feet of lumber were destroyed. At that time wild
+animals raced into the log houses of settlers in order to escape the
+flames. In one instance, placed on record by a forester, a mountain lion
+actually sought shelter under a bed.
+
+In that case, too, the fire virtually held its ruthless way until it
+burned itself out, as there were no trails, no telephones, no provisions
+for the fire fighters. The men of the forest patrol were each guarding a
+hundred thousand acres. In the more civilized countries of Europe, a
+thousand acres is considered a large district for one man.
+
+It was hot and close in the odd little valley on the mountain side.
+There seemed a premonition of greater danger in the very air--the
+lifeless air which seemed to dry the lungs beyond power of action. The
+wind, coming over the blazing forests, struck hot upon the face and
+scorched the lips, while the acrid smoke filled the eyes, the ears, the
+nostrils.
+
+It seemed to Ned that everything east of the Kootenai river must be on
+fire. Now and then, drawn by some wayward current of air, the thick
+smoke lifted in the little cup-like valley, and the cowering wild
+animals could be seen, huddling together in the terror of the time, deer
+no longer afraid of lion or bear, lion and bear forgetting to mark their
+prey.
+
+Finally, anxious to know the extent of the disaster, so far as it might
+be judged by a personal view of the country west of the valley, Ned left
+the boys in charge of the aeroplane and crept toward the rim of the cup.
+Jimmie saw him leaving and started on after him, but Jack drew him back.
+
+"Let him go alone, for once," Jack said, "he's only going to find out
+where this menagerie of wild animals comes from."
+
+Jimmie settled sullenly back by Jack's side, resolved to break away at
+the first opportunity and follow the patrol leader.
+
+When Ned gained the elevation he sought, the procession of wild animals
+had come to an end, although birds, frightened and singed by the flames,
+were calling from the sky. Everywhere rolled billows of smoke, blown on
+ahead of the line of fire and in a measure concealing its fatal advance.
+
+Now and then, however, a spurt of hot wind came over the burned waste
+and lifted the curtain for an instant. Then the boy saw that the fire
+was crawling up the slope, not racing as it had earlier in the day, but
+moving steadily, sweeping the earth of the undergrowth, but leaving many
+large trees.
+
+The danger was decreasing there, but lower down the flames were
+consuming everything in their path, eating down great trees and leaving
+fiery, straggling columns to consume them to ashes. Ned thanked his
+stars that the growths on the slope were not dense enough to foster such
+a blaze as that which burned below.
+
+It has been stated by those who know that ordinary care would have
+prevented most of the devastating forest fires which have raged in the
+Northwest. Experts claim that forests should be burned over under
+careful supervision, every three or four years. This, they say, will
+prevent the accumulation of inflammable material such as caused the
+terrible losses of August, 1910.
+
+Ned saw at once the expediency of the proposed remedy. He knew that
+resinous spines, steeped in the drippings of pitch and turp from the
+overhead branches, had lain many inches deep around the trunks of the
+trees, beneath fallen boles, and at the roots of the undergrowth. This
+accumulation made the extinguishing of forest fires impossible. He
+understood that the government had virtually provided for what followed
+by permitting this material to accumulate year after year.
+
+It is declared by foresters and others who strove to check that wall of
+fire that it advanced at the rate of a mile a minute between the
+Kootenai river and the foothills. Below where Ned lay was a burning
+furnace. It was so hot that he dare not lift his face a second time, and
+so he moved back to the aeroplane, which he found still safe from the
+flames, and the wild creatures crouching in the center of the valley.
+
+"What are the prospects?" Frank asked, speaking with his lips close to
+the ear of the patrol leader, for the roaring of the flames rendered
+ordinary conversation difficult.
+
+"There is safety here," Ned replied, "but everything to the west seems
+to be burning."
+
+"Gee!" Jimmie cried, looking Ned in the face, "how would you like to
+meet a friend with a basket of ice?"
+
+"Ice wouldn't last long here," Frank said.
+
+"Not if I got hold of it!" Jimmie grunted.
+
+As the line of fire came nearer to the top of the slope the air grew
+hotter, the smoke denser and more stifling. Pat remembered that a pail
+of water from a spring had been brought to the vicinity of the aeroplane
+soon after Ned landed, and the boys wet their handkerchiefs and bound
+them over their eyes and mouths.
+
+As the heat increased the wild creatures crowding together ominously.
+When a feeble beast was trampled by a stronger one, or when a rattler
+struck at the leg of a bear or deer, there was a cry of pain and a quick
+milling of the pack.
+
+"If this doesn't end soon," Frank shouted to Ned through his
+handkerchief, "there will be a stampede here. Then it will be all off
+for us."
+
+Ned looked around the little circle before replying. The boys certainly
+looked like "white caps" with their sheeted faces.
+
+"We'll have to wait and hope for the best," he said. "If the animals
+come this way, we must stop them, so far as we are able, with our guns
+and electric flashlights."
+
+Presently night fell, and the wind quieted a little at the setting of
+the sun. In a short time the clouds rolled away in sullen, threatening
+groups, and the stars looked down on the forest tragedy. Later, there
+would be moonlight.
+
+"I wonder if all the world is burned, except just this mountain?" Jimmie
+asked, taking the handkerchief from his face and wiping the smoke out of
+his inflamed eyes. "It looks that way."
+
+"There seems to be enough left to hold a lot of heat," Jack said. "I
+don't believe it will ever be cool again."
+
+"If we'd only saved that brigand steak!" wailed Jimmie.
+
+With the half light and the cooler air there came a commotion in the
+mass of forest creatures in the center of the valley. It was night now,
+and they seemed to feel the mounting of their wild instincts to be up
+and away on the hunt.
+
+Under the stars, one by one, they slunk away, bears and mountain lions
+turning sullenly toward the lesser beasts, but still too terrified by
+what they had passed through to feel the pangs of hunger. In half an
+hour the menagerie had vanished, some to the mountain, some over the
+slopes to the north and south. The boys drew long breaths of relief when
+the shambling figure of the last bear disappeared.
+
+Once Jack drew his gun on a fat old buck who seemed desirous of
+investigating the aeroplane, but Ned saw the action and checked the
+slaughter.
+
+"Let him alone," he said. "He's lived through this hell on earth, so
+give him one more chance."
+
+The boys now began gathering up their scattered utensils, restaking the
+tents, and preparing supper. Jimmie proposed another brigand steak, but
+Pat insisted that he never wanted to get near enough to a fire to cook
+again, so they made an indifferent meal of biscuit and tinned pork and
+beans, not even going to the trouble to boil coffee.
+
+While they were eating a gunshot came from the east, followed by the
+challenge of a chanticleer.
+
+"What do you know about that?" demanded Jimmie.
+
+"I suppose," Jack complained, "that we've been eating a picked-up supper
+within a few rods of a farmhouse, or cattle ranch!"
+
+"You might pry open some of the rocks back there," Pat observed, with
+sarcasm, "and see if you can find the house you speak of. It was a human
+throat that crow came from."
+
+"Sure it was!" cried Jimmie. "It was a Boy Scout call. Now just see me
+get him to talking."
+
+"What's a Rooster patrol chap doing here!" asked Jack. "I guess we are
+all having bad dreams."
+
+Jimmie did not reply. Instead he put his hands to his throat and in a
+second a long snarling wolf cry came forth, rising into a shrill call,
+as if summoning a pack at a distance.
+
+"We'll see what he knows about that," the boy said.
+
+As they listened the challenge of the chanticleer came once more. This
+time Jack answered it with the growl of a black bear, which seemed to
+Frank to be a great improvement on his practice stunts in the Black Bear
+Patrol club rooms in New York.
+
+This odd exchange of greetings kept up for some moments, and then the
+figure of a boy of perhaps seventeen was seen in the uncertain light,
+making slow progress down the mountain, a short distance to the north.
+He carried a haversack on his shoulders and was dressed in the khaki
+uniform of the Boy Scouts of America.
+
+"He must be used to mountain work," Jack remarked, as the boy leaped
+lightly from ledge to ledge and finally dropped into the valley. "I
+couldn't do that, even in broad daylight, to save my life!"
+
+The stranger now advanced to the group of boys and gave them the half
+salute of the Boy Scouts, standing with right arm straight out from the
+shoulder, palm outward, three fingers standing vertical, the thumb
+crossing the palm to rest on the bent-in little finger. Ned replied with
+the full salute, which is made with the hand in the same attitude, only
+at the forehead.
+
+"What does the badge say?" demanded Jimmie.
+
+"Be prepared!" was the quick reply.
+
+"For what?" was the next question.
+
+"To assist those in distress."
+
+"You're all right," Jimmie shouted. "What patrol?"
+
+"Chanticleer, Denver," was the reply.
+
+"That accounts for the way you lighted down from the mountain," laughed
+Ned.
+
+"I've got used to climbing in walking the streets of my home town,"
+smiled the other. "Is Ned Nestor here?" he added. "My name is Ernest
+Whipple; I'm looking for Mr. Ned Nestor."
+
+"Here he is, the only good-looker in the bunch," Jack laughed, pushing
+Ned forward. "What do you want of him?"
+
+"My father is connected with the Secret Service at Washington," was the
+reply, "and he posted me as to what was going on here. Said I might come
+out and join the party, if Mr. Nestor would permit it. What do you say?"
+
+Of course the son of a man connected with the Secret Service at
+Washington--a man who undoubtedly knew all the plans of the men who had
+sent Ned into the Northwest--was not to be ignored, but at the same time
+Ernest would have been received into the party on the strength of his
+own engaging personality, his own frank manner. From the very first
+moment he was a favorite with all the boys.
+
+"You're as welcome as the flowers of May!" Frank cried. "Been to
+supper?"
+
+"Last night!" grinned Ernest. "My haversack is empty--also my stomach. I
+had to take to the mountain in order to keep out of the fire, and
+couldn't connect with a grub stake."
+
+"Then there are fires east of the divide?" asked Ned.
+
+"Sure," was the reply, "although they are nothing like the ones over
+here. The foresters are watching them, and there is little danger of
+their getting a big start."
+
+"Where did you find foresters?" asked Ned, wondering if the men who had
+sneaked away from the cavern were not posing as foresters waiting to do
+further mischief.
+
+"They are in camp beyond the summit," was the reply. "They told me they
+had patrols all through the lower levels."
+
+Jack gave a description of the man who had visited the camp on the
+plateau, and was not at all surprised when Ernest identified the fellow
+as the apparent leader of the band of foresters he had passed on his way
+west.
+
+"I see that you don't believe the men are foresters," Ernest said,
+looking into Ned's anxious face. "Well, to tell the truth, I doubt it
+myself. I heard some talk there that set me thinking, after I got away.
+There was a man there who had just arrived from San Francisco, they
+said, and he was doing a good deal of kicking about something that had
+been done, or hadn't been done. I don't know which."
+
+"Can you describe the fellow?" asked Ned, a quick suspicion coming to
+his mind.
+
+"Of course I can," was the reply, and the remainder of the answer gave
+an accurate word photograph of one Albert Lemon.
+
+Ned was thinking fast. How had Lemon reached the eastern side of the
+divide so quickly. He, himself, had traveled swiftly from San Francisco,
+leaving soon after his exit from the bachelor apartment where the
+strange and not entirely satisfactory interview had taken place. He had
+left the man who claimed to be Albert Lemon half dazed and weakened from
+the effects of opium--still weary from a long and exhausting journey, as
+shown by his clothing, and yet the fellow had beaten him out in the race
+to the mountains.
+
+Why? Certainly not to take charge of the body of his unfortunate friend,
+for the grave was not there, but in a little hollow away to the north
+and near the lake. His business seemed to lie with the outlaws who had,
+apparently, committed the crime. Why? Had the man been killed as the
+result of a conspiracy between the two interests?
+
+This point was worth looking into, for the motive for the deed might
+also prove to be the motive for other crimes--among them the burning of
+forests.
+
+
+
+
+CHAPTER X.--CHASING THE MILKY WAY.
+
+
+While the boys were exchanging experiences with Ernest Whipple, talking
+over Boy Scout matters and arranging for a sleeping place for the
+stranger, Ned was busy with his aeroplane. It had not suffered in the
+least from the heat and wind, and there was plenty of gasoline on hand
+for a journey which he was thinking of taking.
+
+"Where are we goin' to-night?" Jimmie asked, finally, strolling over to
+the spot where the great bird lay.
+
+"As the wind is right," Ned laughed, "I thought I'd take a sail over the
+divide and see what the alleged foresters are up to."
+
+"All right," the boy said, "just wait until I get a big blanket to wrap
+up in and I'll go with you."
+
+Ned smiled at the determination of the lad to keep close to his side. He
+knew that Jimmie dreaded the very idea of leaving the solid earth that
+night, still he found him willing to make the ascent merely for the sake
+of being in his company.
+
+"All right, kid," he said. "You may go if you want to, but it may be
+morning before we get back to camp."
+
+"You can't remain in the air all that time," Jimmie said.
+
+"I am fully aware of that," Ned replied, "but I can drop down over on
+the other side and rest and tinker with the machine--if she doesn't work
+just right."
+
+"You haven't got gasoline enough," urged Jimmie, who would have argued
+Ned out of the notion of the night flight if possible, but who was
+determined to go with him if he went.
+
+"The first thing I do," Ned replied, "will be to fly over the Great
+Northern right of way and fill up with gasoline. Besides filling the
+tanks, I shall carry a lot away in an aluminum keg I have provided for
+that purpose."
+
+"Well," Jimmie said, with a tired sigh, "I should think you'd been
+through enough to-day and to-night, without goin' off in the dark, but
+I'm goin' if you do."
+
+After talking with the others regarding his intentions, and warning them
+to keep a sharp lookout during his absence, Ned assisted Jimmie to his
+seat and the two were away. There was scant room for a rise between the
+spot where the machine lay and the foot of the range, but Ned had little
+difficulty in getting into the sky and swinging along in the breeze.
+
+It was now after ten o'clock, and the moon was high in the heavens. To
+the east the dark passes of the mountains showed green and misty in the
+moonlight. To the west the burned spaces looked dark and forbidding,
+with smoke half hiding the ruin that had been wrought. Jimmie clung to
+the machine and insisted that Ned was chasing the Milky Way when he
+lifted the aeroplane up the level of the divide.
+
+Before crossing the divide, however, Ned flew to the Great Northern
+right of way and filled his tanks with gasoline, also filling the extra
+keg. The machine, which was an improved Wright, was then turned to the
+north-east. So perfect have aeroplanes now become that even
+inexperienced drivers may sometimes venture into the air with them with
+impunity, still it is well known that it is more the man than the
+machine that decides whether there shall be a tumble or a successful
+flight.
+
+The aeroplane is a wonderful invention, yet the point which really makes
+it so serviceable is a very simple one. For years inventors studied ways
+of making a heavier-than-air machine sail through the sky like a bird.
+Then the gasoline engine came, and all the rest seemed easy.
+
+But no one could keep control of the aeroplane. It moved about according
+to its own whims, and tipped drivers out at its own sweet will. Then the
+Wrights thought of lifting and lowering the planes to represent the
+wings and feathers of a bird. The secret had been found and required
+only experience and practice. Here was a machine light enough to fly,
+yet strong enough to carry with safety its powerful engine and two or
+more passengers, if there is room provided for them.
+
+It is so stout that a man may walk over it while it lies on the ground,
+and yet so delicate in control when in the air that a slight pull on a
+lever will dip one wing, lift the other, and at the same time turn a
+vertical tail-rudder about to give the necessary balancing pull with
+almost the instinctive adaptability of a bird's wings and feathers.
+
+And this wonderful machine, while speeding through the air with the
+velocity of an express train, can be halted almost instantly and whirled
+about on its tail. It will be seen that it is the man at the levers who
+makes or breaks a journey in the air. One man may do almost anything
+with a machine, while another may send himself to eternity with the same
+one. It was Ned's good fortune that he was naturally ingenious and quick
+to make his hands follow the impulses of his brain.
+
+When a person is thundering through the air, a thousand feet above the
+earth, he must remain perfectly calm, even with the engine thundering
+behind his ears, tears running in streams down his face, and the wind
+fluttering his clothes into rags and ravelings, as he wishes he was back
+on land.
+
+Besides, there are no level plains in the air, as there are on earth.
+Every bird-man knows that he is liable to come up against a fierce
+current or tumble into a hole in the atmosphere at any moment. While
+traveling in water one can see what is ahead and on both sides, but this
+is not so in the air. The currents, swirls, eddies, holes, do not show
+at all.
+
+When Ned left the cache where the gasoline and provisions had been
+hidden away, he put on half speed, swinging steadily skyward on a broad
+spiral. His purpose was to pass over the summit and have a look at the
+forests on the east side.
+
+The passenger's seat in the Wright machine is in the middle. The engine
+is at his right and the driver at his left, so that the balance is the
+same whether an extra person is carried or not. Jimmie was glad of this,
+for it placed him close to Ned. In that half light, with the earth far
+below, with the pounding of the engine and the whistling of the wind,
+the boy felt the need of close human companionship.
+
+He sat in a wooden seat with his back against the rest, holding to one
+of the uprights with both hands, and resting his tingling feet on a
+cross-bar. A guy-wire passed across in front, close to his chest, so he
+was now fastened in.
+
+He wanted to talk with Ned, to hear the sound of his voice, but the
+clamor of the engine prevented that, so he just sat still and looked
+down on the flying forest below. It seemed to him, at least, that the
+forest was moving, while he was standing still in the starlight.
+
+Up the aeroplane went, and still higher up. Jimmie saw the great divide
+below, and saw little red specks in the forests of the eastern slope
+which denoted forest fires not yet grown to maturity. After passing the
+summit Ned saw the campfire of the men Ernest had spoken of. He passed
+them, swung around a circle lower down, selected a spot where he thought
+he could land with safety, and dropped down.
+
+Jimmie declared afterwards that he felt as if he had been thrown out of
+the window of a twenty-story building--and the highest window at that.
+When the aeroplane came into the shadows of the high trees where the
+landing was being made he knew that a wind was blowing at the surface
+and feared that the machine would be carried along on the ground and
+dumped over into a canyon.
+
+The machine sank gracefully into a glade rather high up on the slope,
+and the boys alighted to stretch their legs. Ned's first move was to see
+if there was plenty of room for him to get out. What he found was an
+incline to the east, an incline ending at a great canyon, into which he
+would have been hurled had the aeroplane run fifty feet farther on the
+ground.
+
+"I think I can make it," he said, "but it is risky. It wouldn't be nice
+to take a header a thousand feet down."
+
+After the inspection of the locality Ned extinguished all the lights and
+sat down to map out his plans for the remainder of the night. There were
+the usual noises of the forest, as found at night, but no human sounds
+intruded.
+
+Ned knew that the clamor of the engine must have been heard by the men
+in the camp he had flown over, and he had no doubt that the outlaws
+would make a quick excursion to his landing place, if they could
+determine where it was. So he put out the lights and listened for some
+indication of the approach of the others.
+
+"They won't find us in a thousand years," Jimmie volunteered, as the two
+sat close together under a great tree.
+
+"I hope not," Ned replied, "for then we shall have a better chance to
+find them."
+
+"What do you want to find 'em for?" questioned the boy. "You can't pinch
+'em, 'cause you haven't got the proof, an' you couldn't if you had the
+proof, 'cause there ain't enough of us. They'd eat us up like spinach."
+
+"You are right as far as you have gone," Ned replied, "but you have not
+gone far enough. What I want now is to find out what they are doing
+here. And, also, I want to find out about that fellow from San
+Francisco. If the description is any good, he was in the city when I
+left it, and I don't see how he ever got here so soon. I came part way
+on an aeroplane, but it seems that he traveled farther and beat me out."
+
+"What's he got to do with it?" asked Jimmie. "What did you find out in
+the city? You won't have no luck if you don't tell me all about it."
+
+So, while they waited, Ned told him "all about it," while the boy sat in
+the dusk with his eyes and mouth both opened wide at the mystery of the
+thing.
+
+"I don't believe Albert Lemon ever got out here so soon," the lad said,
+when the story was told. "He couldn't."
+
+"Then who is the man from San Francisco?" asked Ned.
+
+"It can't be the dead man?" questioned Jimmie.
+
+"You saw him buried," Ned answered.
+
+"Then I give it up!" Jimmie said.
+
+The two sat there in silence a long time, then Jimmie gave Ned's arm a
+pull and pointed to a flickering light in the forest just above the
+glade where the aeroplane rested.
+
+"They think you've landed somewhere here," the boy said, "an' have set
+fire to the woods."
+
+"I think you have guessed it," Ned said. "However, the blaze won't run
+very fast up there, for the undergrowth is scanty, so we've got plenty
+of time to get out of the way."
+
+Jimmie scrambled up the slope, clinging to rocks and roots with both
+fingers and feet, and ran toward the blaze. Ned watched the little
+fellow dashing along with no little anxiety, for the outlaws might be
+there in the thickets, watching for some attempt to be made to lift the
+aeroplane.
+
+He saw Jimmie recklessly climb to the top of a great rock which jutted
+out from the side of the mountain and saw his figure outlined against
+the growing blaze on the slope above. Then the fire died down, as if for
+want of material, and the top of the rock could no longer be seen.
+
+Ned listened, but Jimmie did not return. The effort to create a general
+conflagration on the mountain side had evidently failed, for there was
+little to burn save the green boles of trees, that section having been
+swept by fire a year before.
+
+Not daring to leave the aeroplane for even an instant, Ned awaited the
+return of the boy with premonitions of trouble in his mind. Presently he
+heard a shot, then a cry, and after that a brutal laugh. The outlaws
+were nearer than he thought.
+
+There was only one thing for Ned to do, and that was to get the
+aeroplane into the sky immediately, and so once more place it beyond the
+reach of the outlaws. There was nothing he could do to aid Jimmie, he
+reflected, sadly, by remaining there.
+
+It was no task at all to start the rollers down the incline, but the
+canyon threatened if he did not get it off the ground in quick time. He
+knocked the stones out from under the wheels and sprang into his seat.
+The machine, gaining momentum, moved on sedately. It had acquired a fair
+rate of speed when he came within a few feet of the canyon.
+
+Then, after letting it get all the headway possible in that confined
+space without coming too close to the canyon, Ned pulled the lever which
+tilted the front rudder planes. Trifling as the deflection was the
+man-made bird felt its influence and rose from the slope as if endowed
+with life.
+
+It reached the edge of the descent some distance in the air, and the boy
+was congratulating himself on the success of his unaided rise when the
+big machine began to sag as if dropping to the ground, five hundred feet
+below.
+
+The west wall of the canyon ran straight down, and it seemed to Ned that
+he was following it, like an iron spike thrown off the ledge. He knew
+very well what had occurred. He had fallen into one of the down-tipping
+currents so frequent in mountain districts.
+
+The air, he knew, was sliding down the precipice just as water tumbles
+over a dam. If it turned, as it might, when it struck the lower strata
+of air, he might secure control of his machine and manage to lift it out
+of the canyon. If it did not, he would doubtless fall to the rocky floor
+of the canyon, and lie there until some chance hunter or forester came
+upon a heap of bleaching bones and the wreck of an aeroplane.
+
+But even at that swift pace downward, and at that exciting moment, Ned
+found himself puzzling over the strange sight he saw in a break in the
+wall of the canyon. It was a large opening he looked into, and strange
+figures were gathered about a cooking fire.
+
+
+
+
+CHAPTER XI.--THE LUCK OF A BOWERY BOY.
+
+
+Jimmie opened his eyes and looked about. It was a gloomy niche in a
+perpendicular wall that he looked out of. Rock to right and left and
+rear. In front a velvet summer sky, with stars winking over a vast
+stretch of broken country. There was a ledge a foot in width outside the
+entrance to the niche, but the boy could not see how long it was, or
+where it led to.
+
+His head ached and there was a drawing sensation to the skin of his
+forehead and right cheek, as if some sticky substance had congealed
+there. When he reached a hand up to see what the trouble was he found
+that his head was tied up in a cloth. There was no one in sight to ask
+questions of, so he arose to a sitting position and leaned forward.
+
+The action brought on a whirl of dizziness, and he dropped back against
+the wall for support. He knew then that he had received a hard blow on
+the head, and that he had lost considerable blood. Once before in his
+life he had felt that dizzy weakness, and that was after an artery had
+been cut in his leg and he had nearly bled to death before reaching a
+hospital.
+
+When he lay back trying to get something like a balance in his brain, he
+saw that it was near midnight. He knew that by the stars, for he had
+watched them many a hot night, lying on his back on a dray backed up
+some alley down near the East river, in New York.
+
+There were certain stars which always occupied just such a position at
+midnight in New York. He did not know their names, but he knew that at
+midnight in Montana they would not be so far advanced across the sky.
+Therefore he looked for the stars as they appeared at nine o'clock on
+the Atlantic. When he found them he knew from their location that it had
+been something over an hour since he had left Ned and the aeroplane.
+
+The three hours difference in time between New York and Montana--three
+hours in round numbers--would make the midnight stars three hours late,
+of course. Anyway, the boy was pretty certain of the time.
+
+Then his mind went back to Ned and the aeroplane, and the canyon in front
+of the landing place. He recalled the stop, and remembered leaving Ned
+to see what was doing in the way of forest fires. He remembered, too,
+getting up on a high rock to look over at the creeping flames.
+
+But strange to say he did not remember getting down again. The next
+thing on the record of his mind was that niche in the wall and the stars
+shining down out of a summer sky, the same stars he had looked at in old
+New York. Of course he had been struck the blow he had received while
+mounting the rock, otherwise he would know something of the attack.
+
+His mind did not have to travel along the records of the past very far
+to convince him that he had made a mistake in leaving Ned. Of course he
+had been "geezled" by the outlaws, as he expressed it, and of course the
+boys would delay the business they were on in order to look him
+up--which, he reluctantly admitted to himself, would be a waste of time,
+as any boy capable of doing such foolish stunts certainly was not worth
+the trouble of looking up.
+
+Presently the pain in his head became less violent and the dizziness in
+a measure passed away. Then he pushed out to the edge of the ledge and
+sat with his feet hanging over. It was a straight drop down. Below he
+could see a stream of water running along the bottom of the canyon.
+
+Out, perhaps two hundred yards from his resting place, he saw a slope
+half covered with trees. He looked down into the gulf in the hope of
+seeing the aeroplane, but it was not in sight. Ned must have taken it
+away. Or he might have been overpowered and the machine broken up.
+
+Of course the outlaws would break up the machine if they secured
+possession of it. They would not dare use it in that region, and it was
+about as handy a thing to ship away secretly as a white elephant.
+
+There were no lights in sight anywhere, save a slight glow of coals away
+down at the bottom of the canyon. That might be the remains of the
+aeroplane, or it might be a bit of forest fire which had not burned
+itself out. Very much disgusted with himself, the boy leaned farther out
+wondering if there wasn't a ledge which wound its way to the bottom of
+the canyon, or to the summit above.
+
+So intently was he studying on this proposition that he did not hear
+footsteps approaching, nor did he realize that there was any human being
+near him until he felt a hand laid lightly on his shoulder.
+
+"Be careful, young man," the voice said, "or you'll get another tumble.
+How do you feel by this time?"
+
+"Fine!" cried the boy, turning a pair of astonished eyes toward the
+south, where a bulky personage stood blocking the ledge to the extent of
+obscuration.
+
+"Well, don't take any more chances, then," said the bulky person, and
+Jimmie was forced, not ungently, back into the niche.
+
+The man entered after the boy and threw himself down on the stone floor
+of the cut in the wall of the canyon. He was short and stout, with a
+double chin and a pointed forehead which gave his face the appearance of
+being engraved on a lemon. He was quite bald, and his hair, that which
+remained, was turning gray. His eyes were steel blue, and his mouth one
+long, thin-lipped slit between fat cheeks.
+
+Jimmie did not like his looks at all, and he resented the patronizing
+voice and manner. So he leaned sullenly against the wall and waited for
+the other to open the conversation. He had not long to wait, for the man
+was busy in a moment.
+
+"How did you get that fall?" he asked.
+
+So, Jimmie thought, they were going to claim that he had a fall, and
+that they had found him, and cared for him gently, and were now ready to
+do anything in the world for his comfort. The boy decided that the
+correct course for him to pursue was to follow the lead of the other.
+
+"Guess I slipped off a rock," he said, knowing very well that he had
+been knocked off his feet so suddenly that he had instantly lost
+consciousness.
+
+"What were you doing there?" was the next question.
+
+"Why, I had been out in the aeroplane, and I got out to see if the
+forest fire I saw was going to be anything serious, and then I tumbled."
+
+"Where is the boy who was with you in the aeroplane?" asked the other.
+
+Jimmie replied that he had no idea, which was, of course, the answer
+expected of him. His questioner remained silent a moment, looking out
+over the rugged land to the east. When he spoke again it was to ask:
+
+"What are you doing in the Rocky Mountains?"
+
+Jimmie thought that was a cheeky question, and a useless one, for he had
+no doubt that the fellow knew nearly as much about his business as he
+did about his own.
+
+"We're on a vacation," he replied. "Five of us have a camp over on the
+other side of the divide. We're just playing prospectors."
+
+"Very nice vacation for you all," the other said, "but you ought to be
+more careful with your fires. You started a large conflagration
+yesterday."
+
+So the Boy Scouts were to be accused of that! Jimmie wished at that
+moment that the other boys were there. He wanted to tell this fat
+hypocrite what he thought of him and stand a fair show in the fracas
+which might follow.
+
+"I don't think we set any fires," he said. "The fires started a long way
+from our camp."
+
+"I know what I'm talking about," the other said.
+
+Jimmie did not reply. He was wondering what would be the next move of
+the fat party, and whether Ned or the boys left in camp would be out to
+look him up before the morning.
+
+"I am in charge of this district," the other went on. "I'm Captain
+Slocum of the forestry force."
+
+Jimmie did not believe it, but did not say so. He only stared at the
+other in a manner which nettled his dignity.
+
+"I have been watching you boys ever since you have been here," Captain
+Slocum went on. "I didn't know what you were up to, and so I watched."
+
+"Yes, sir," said Jimmie, quite humbly, though angry enough to fight the
+man single-handed.
+
+"It seems that you have left forest fires wherever you have camped,"
+Slocum went on, with an all-knowing air. "To-night I sent a party of
+foresters over to the camp to arrest you all."
+
+"Yes, sir," replied Jimmie again, shutting his lips hard in order to
+prevent saying a great deal more.
+
+"Do you think they will find this Ned Nestor there?" Slocum asked, then.
+
+"I don't know whether he could get his machine back to the camp," Jimmie
+replied.
+
+"Well, wouldn't he go without it?"
+
+"No, sir; I don't think he would, unless it was certain that he could
+not take it with him."
+
+"We'll find him, anyway," Slocum continued.
+
+"Where are you goin' to take us for trial?" Jimmie asked.
+
+"We'll have to consider that part of the matter later on," was the
+reply. "The first thing for us to do is to lock you up good and tight
+and stop the setting of forest fires."
+
+"Yes, sir," replied Jimmie, still humbly, but still thinking what he
+would do to this fat falsifier if he ever got a chance.
+
+"I'm glad you confess," Slocum said.
+
+"I didn't," said Jimmie.
+
+"Why, yes, you did," insisted the other. "You admitted setting the
+fires."
+
+Jimmie made no reply. Far down in the canyon he saw a glint of flame. It
+was not a forest fire. It was not even the red light of a campfire or a
+lantern. The light was white, and the boy knew it for what it was--an
+electric searchlight, such as Ned always carried on his aeroplane trips.
+
+Slocum did not seem to see the light. His eyes were fixed on the face of
+the boy he was talking with, although the features did not show very
+distinctly in the dim light of the night.
+
+"Well, to tell you the truth, we've already captured this Ned Nestor,"
+Slocum added, maliciously, Jimmie thought, "and no doubt my men have
+also captured those at the camp. Nestor broke a leg in trying to get
+away, but when he was fairly cornered he confessed everything."
+
+"Yes, sir," answered Jimmie.
+
+There was nothing else the boy could say without putting himself in the
+way of a beating. If he had expressed his opinion of this story no doubt
+he would have been given physical punishment for his frankness.
+
+"And so," Slocum smiled, "you may as well continue the confession you
+began."
+
+Jimmie recognized this as clumsy work in the third degree, but he did
+not say so. He was watching the light below. Now it disappeared behind a
+great rock or tree. Now it came out in the opening again and moved about
+in a circle.
+
+"Ned is examining his 'plane, preparatory to going back to camp," the
+boy thought. "Wonder if he's been all this time lookin' for me?"
+
+The boy paid little attention to what Slocum said after this. Most of
+the time he was looking into the sky, or anywhere rather than where his
+thoughts were fixed. He had no intention of directing the gaze of the
+alleged forester to what was going on in the canyon.
+
+Directly he saw the flashlight flutter over the white planes then become
+stationary. Ned, he knew, was getting ready to make a flight. He could
+imagine what the boy's feelings were, for he knew Ned's affection for
+him. Indeed, it was with a heavy heart that the patrol leader left the
+place without Jimmie.
+
+"And there is also a suspicion that you boys are interested in getting
+opium over the border without settling with Uncle Sam," Jimmie heard
+Slocum saying, as he watched the aeroplane move forward, lift for a
+moment, and then drop down out of sight. He knew of the precipice just
+ahead of the machine, and trembled for fear that Ned had not been able
+to lift the aeroplane, but had tumbled into the canyon with it.
+
+"Anyway," Slocum continued, "we shall place you under arrest for setting
+fire to the woods and also for smuggling."
+
+Just at that moment Jimmie was not at all interested in what Slocum was
+saying to him. He took no interest whatever in any threat made by the
+fellow. He was watching the canyon for some sign of the reappearance of
+the aeroplane.
+
+After what seemed an eternity to the lad he saw the light again, this
+time higher up than before. It was lifting slowly, turning round and
+round in a spiral, and Jimmie knew that there was no room to mount into
+the sky in a straight line. Ned's control of the machine was wonderful,
+and it lifted gradually until it was above the line of the hills on the
+other side and shot away to the west.
+
+Then Slocum saw it. Jimmie blamed himself for calling his attention to
+it by lifting his head to follow the flight across the sky.
+
+"There is another aeroplane," Slocum said.
+
+Jimmie could not restrain a laugh, which intruded oddly enough on the
+tense silence of the moment.
+
+"You don't think it is Nestor, do you?" Slocum asked.
+
+"Yes, sir," replied Jimmie, still humbly.
+
+"But he must have taken a drop down the canyon," urged Slocum.
+
+"Yes, sir," replied Jimmie, "but you said you had captured him!"
+
+Slocum eyed the boy with rage in his eyes. He knew very well that while
+he had been telling of Ned's capture and confession, Jimmie had been
+watching his chum get his aeroplane out of the canyon.
+
+"You haven't even thanked me for getting you out of the mess I found you
+in, and doctoring up your wound," he said, presently, resolved to keep
+on good terms with the boy for a short time longer, if it was possible
+to do so.
+
+"Thank you, sir!" Jimmie said, very modestly. "I think I must have
+received a good bump on the head."
+
+"Indeed you did," smiled the other.
+
+After a little further talk Slocum led the boy away to a cavern in the
+wall of the canyon which seemed to the weary lad to have no end. He saw
+several people lounging about as he passed through a large chamber, but
+paid little attention to them.
+
+At last Slocum halted in a little alcove opening from a second chamber,
+in which were assembled at least a score of Chinamen.
+
+"These people won't harm you," he said to the boy, swinging his arm
+about to include the group. "Uncle Sam is trying them out in the forest
+service, I don't think much of the idea myself, but I'm not the boss."
+
+Then Slocum went away and Jimmie lay down and watched the Chinamen.
+Listening, he heard one of them speaking in English, then in Chinese. He
+knew that he had heard that peculiar voice and dialect before and
+devoted his whole attention to the fellow.
+
+"Well," he muttered, in a moment, with a grin, "I'm havin' the luck of a
+Bowery boy in this deal, an' that is the greatest luck in the world."
+
+Then he fell to wondering what Chang Chee, the keeper of one of the
+worst Chinese restaurants on Doyers street was doing there, in the heart
+of the Rocky Mountains, mixed up with alleged foresters.
+
+"Just wait until I see Ned!" the boy mused. "I'll put him next to
+somethin'. He'll be glad he brought me with him!"
+
+Then the boy's thoughts went back to the camp in the Valley of the Wild
+Beasts, as he called it. Slocum might have told the truth about the
+attack on the boys, and they might be in trouble at that moment. He
+wondered, too, if, in case they were taken prisoners, they would be
+brought to the cavern.
+
+"Anyhow," the lad mused, "they never intend to let me get out of this.
+If they did, they wouldn't have permitted me a sight of the Chinks.
+Unless I sneak away, there'll be an accident some day, an' then there'll
+be no more Jimmie McGraw!"
+
+The boy was tired and weak, so that even such serious thoughts as these
+could not keep him awake. Wondering what conditions Ned had found at the
+camp, after soaring out of the canyon, he dropped his head against the
+stone wall of the alcove and was soon in a deep sleep. The fumes of
+opium with which the cavern was filled might in a measure have
+contributed to this, but, anyway, nature was exhausted, and the boy's
+slumber was heavy and dreamless.
+
+
+
+
+CHAPTER XII.--A MEMBER OF THE OWL PATROL.
+
+
+When Jimmie awoke the fire which had burned in the cavern had gone out,
+and those who remained in the chamber seemed to be fast asleep. He
+tumbled out of his alcove, still feeling weak and dizzy, and moved
+toward a hanging rug which closed the entrance to the place.
+
+He drew one side of the rug back and saw the white light of day. The sun
+seemed to be high up in the sky, for the ledge at the front of the
+cavern showed a streak of gold. Two Chinamen sat at the entrance to the
+outer cave, and when he advanced toward them they waved him back.
+Instead of retreating he stood regarding them with a puzzled look on his
+face.
+
+One was Chang Chee, the keeper of the disreputable Chinese dive on
+Doyers street, whom Jimmie had noticed the night before, and the other
+was a much younger man--a boy, in fact. When Chang ordered Jimmie back
+the youngster turned toward him a face showing both curiosity and
+interest.
+
+"What's doin' here?" Jimmie demanded, in a moment.
+
+He thought best not to show that he recognized Chang, for he knew that
+the identification of the Chinaman would only add to his peril, if that
+were possible. It was certain that Chang would never permit the
+information that he had been seen there to get out to the government
+officers.
+
+Jimmie's idea at that time was that he had blundered on a gang of opium
+smugglers, although he could not understand why so many Chinamen were,
+apparently, engaged in the illegal traffic.
+
+Chang finally turned his face away, with a frown, and Jimmie advanced a
+step toward the boy, who threw himself carelessly down on his back and
+extended his right arm straight up from the shoulder. Jimmie's eyes
+opened wider, and his breath almost stopped, when he saw the thumb and
+little finger thrown diagonally across the palm of the hand, the tip of
+the thumb covering the nail of the little finger, the three remaining
+fingers pointing upward.
+
+In the excitement of the moment, in the amazement caused by his
+recognition of the Boy Scout challenge, Jimmie lost all caution.
+
+"Say!" he began, but Chang turned a repulsive face and ordered him into
+the rear chamber.
+
+The boy, thankful for the interruption, moved back a few paces,
+believing that the Chinese boy who had given him the sign would
+communicate with him as soon as opportunity offered.
+
+This was the greatest puzzle the lad had ever been called upon to solve.
+Some of the questions he asked himself were:
+
+"How did that Chinese boy become a Boy Scout?"
+
+"Is there a Chinese patrol?"
+
+"Was he permitted to become a member of an American patrol?"
+
+"Why is he mixed up with that disreputable old Chink?"
+
+"Will he help me out of this hole, or will he ignore me?"
+
+Of course there was not one of the questions the boy could answer, so he
+went back to his alcove and sat down, half believing that he had
+imagined the challenge.
+
+As the day wore on the men who had been asleep in the inner chamber
+arose, staggeringly, as if still under the stupefying influence of
+opium, and made their trembling way outside. When they had all
+disappeared Chang pushed the rug aside so as to bring more light and air
+into the place and came and stood looking down on the boy.
+
+Jimmie did not look up. He saw the shrunken figure up as far as the
+knees only. He was resolved not to open any conversation with the Chink.
+If he wanted to talk, Jimmie thought, let him choose his own subject and
+introduce it in his own way.
+
+The yellow face of the Chinaman seemed to take on a more mask-like
+expression--or want of expression, rather--as the silence continued.
+When he spoke it was with a snarl which boded no good to the boy.
+
+"Hungly?" he demanded.
+
+"Hungry?" repeated Jimmie. "You know it! If you've got any rat
+sandwiches or puppy potpies, just introduce me!"
+
+"Flesh!" growled Chang.
+
+"Flesh?" repeated Jimmie. "Oh, yes, you mean fresh? Well, you'd be just
+as fresh as I am if you were as hungry."
+
+"Cheek!" cried Chang. "Kid allels have cheek--an' tummy!"
+
+"Sure," said Jimmie. "Go on an' get me a porterhouse steak with French
+potatoes. I could eat a car of raw onions."
+
+Chang turned away and walked out to the ledge, where the Chinese boy
+stood, looking out into the sunshine. It was a glorious morning, with
+the air clear and just a little sharp, owing to the altitude. Here and
+there little swirls of smoke showed that fires were burning in the
+forest, though none seemed to be close to the range.
+
+Reaching the boy's side Chang addressed a few words to him in Chinese
+and left the cave, turning back, after a few paces, to observe the boy,
+now standing with a long, keen-bladed clasp-knife in his hand. As Chang
+looked the boy ran his finger over the edge of the blade, as if to make
+sure that it was suitable for some purpose he had in view.
+
+With an exclamation of rage Chang charged back at him and snatched the
+knife from his hand.
+
+"You fool!" he cried.
+
+"You let me alone!" shouted the other. "I tell you, I'm going to kill
+him!"
+
+Jimmie heard the words and rose unsteadily to his feet. He recognized
+the voice as that of the boy who had given him the Boy Scout challenge.
+At least it was not that of Chang, and there were only two figures
+outlined against the sky when he looked out beyond the rug, still pushed
+aside.
+
+"Fool! Fool! Fool!"
+
+Chang gritted out the words as he took the Chinese boy by the back of
+the neck and hustled him into the cave. Then he spoke for a minute in
+Chinese and turned away again. Jimmie stepped back into his alcove and
+felt around for a stone, or anything in the shape of a weapon, as the
+boy advanced toward him.
+
+"What does the badge say?"
+
+Jimmie opened his eyes wider than ever, if possible, and stood facing
+the boy, half hiding the stone he had found.
+
+"Be prepared," he replied.
+
+"Then drop that rock!"
+
+Jimmie dropped it and stepped forward.
+
+"Liu, Owl patrol, San Francisco," the Chinese boy said.
+
+"McGraw, Wolf patrol, New York," replied Jimmie.
+
+"You don't look very comfortable in here," Liu said.
+
+"Nixy," replied Jimmie, wondering if the boy really was preparing to
+carry out the threat he had made to Chang.
+
+"You heard what I just said to Chang?" Liu asked.
+
+Jimmie nodded his bandaged head.
+
+"Bluff!" said Liu. "He's watching now to see that I don't make an
+attempt on your life. Had to do it!"
+
+"I see," Jimmie replied, wondering if it wasn't pretty near time to wake
+up.
+
+"Why don't he want me killed?" Jimmie asked in a moment.
+
+"He thinks you have information he needs," was the answer. "Are you
+hungry?"
+
+"That's what Chang asked," Jimmie said, "but he didn't bring me any
+grub."
+
+"He told me to," grinned Liu, "and I told him that I'd kill you if I got
+near enough to do so. He'll hang around until he sees me bring you
+something to eat."
+
+"You ain't so very slow yourself," grinned Jimmie. "Where did you learn
+to speak United States so well?"
+
+"Born in Frisco," was the reply. "The Boy Scouts take me out on their
+hunting trips to do the cooking. That's why I'm here now. I know the
+mountains, and Chang hired me to go along with him."
+
+"An' they took you into the patrol, did they?" asked Jimmie.
+
+"Sure they did," was the reply. "Why not? I'm an American citizen, or
+will be in four years."
+
+"Have they captured any of the others?" asked Jimmie.
+
+The Chinese boy shook his head.
+
+"Have they heard from the men they sent out to capture them?" was the
+next question.
+
+Another shake of the head, then Liu drew closer and whispered.
+
+"Do you see Chang poking his head around that rock in the opening? He's
+watching to see that I don't knife you!"
+
+Jimmie saw the parchment-like face of the old reprobate peering around
+the rock and wanted to heave a stone at it, but knew that this would not
+be good policy. Instead he threw it at Liu, and missed, of course.
+
+"You seem to be wide awake yourself," Liu said.
+
+"Why don't you go and get me some grub?" demanded Jimmie. "I'm near
+starved to death."
+
+"All right!" said Liu, and turned away.
+
+Jimmie was now in a deeper puzzle than before. He had no means of
+knowing whether Liu was telling him the truth. He might be trying to get
+into his confidence in order to gain the information sought, whatever it
+was.
+
+However, in a short time Liu returned with a generous supply of food,
+fried fish, fresh biscuit--the boy wondered how Liu had managed to bake
+them there--coffee, and plenty of tinned goods.
+
+"What's this bunch doin' here?" the boy asked, as he made heavy inroads
+on the fresh fish, coffee and biscuits.
+
+"I don't know," was the hesitating reply.
+
+"I know," Jimmie went on. "They're smuggling opium an' setting fire to
+the woods. They'll all get pinched!"
+
+"I hope so," was the reply.
+
+"It sounds odd to hear a Chinese boy talk straight United States,"
+Jimmie said, after a short silence.
+
+Liu made no reply for a moment. He was watching the ledge outside the
+entrance to the cave. The occasional rattle of pebbles told him that
+some one was standing there, probably just out of sight.
+
+"What is Chang doin' here?" Jimmie asked, presently.
+
+"He's in some scheme with the foresters," was the reply.
+
+"They ain't no foresters!" Jimmie said. "They're timber thieves an'
+smugglers, an' firebugs, an' murderers!"
+
+Liu shuddered but remained silent. After listening a second he went to
+the entrance and looked out. There was no one in sight at first, then a
+roughly dressed fellow came around the angle of the cliff to the north
+and approached him. The fellow was rather short for a man of his width
+of shoulder, and his step was remarkably light and quick for one of his
+apparent weight.
+
+His face was sun and wind-tanned, with plenty of mountain soil on top of
+that. A cartridge-belt encircled the loose jacket he wore and a revolver
+handle protruded from the pistol pocket of his trousers.
+
+"What's the word?" he asked, gruffly, as he came up to Liu.
+
+"Go on in," replied Liu.
+
+Jimmie saw evidences of treachery in the hostile attitude of the
+newcomer and retreated farther into the cavern.
+
+Then he saw Liu doubling up with laughter and stopped. It didn't look
+very amusing to him, especially as the stranger was advancing toward him
+with swift strides. Then something remotely familiar in the set of the
+shoulders, the carriage of the head, attracted his closer attention to
+the figure and he moved forward a step.
+
+"You're a nice little boy to get into a trap like this!"
+
+There was no mistaking that voice. Just how Ned Nestor had secured that
+disguise and found his way to that spot Jimmie did not stop to think. He
+knew that it was his chum, and that was enough. While the two boys
+clasped hands Liu stood regarding them smilingly, at the same time
+watching the entrance.
+
+"How did you ever find this hole?" Jimmie asked, his wonder at the thing
+which had happened mastering all else.
+
+"I saw this cave when my machine dropped into a hole in the air in the
+canyon," was the reply. "The shelf where we landed is just above this
+cavern. There was a fire in the outer room, and numerous Chinamen were
+moving about."
+
+"They're opium smugglers," Jimmie said.
+
+"Man smugglers!" laughed Ned.
+
+"Do you mean that they bring Chinks over the border here, an' so run
+them down into civilization whenever they get a chance?" demanded
+Jimmie.
+
+"That is just it," Ned answered. "We seem to have come upon a lot of the
+articles to be smuggled," he added.
+
+"How did you come across Liu?" Jimmie asked.
+
+"Oh, I met him while I was prowling about not far from the cave, at
+daylight," was the reply. "He helped me get this disguise."
+
+Liu was still watching at the mouth of the cavern, so the boys talked
+freely, with little fear of being disturbed. Ned told of his return to
+the camp, and of the all-night hunt for the missing boy. It took Ned and
+Frank a long time to find the opening the former had seen in his swift
+drop down the canyon, but about daylight it was located.
+
+They had, however, found many Chinamen loitering about, and Frank had
+gone back to camp to reassure the others, while Ned remained on the
+eastern side on the chance of getting into communication with Jimmie.
+While loitering about Liu had come up the slope.
+
+It was quite a long story, that of his getting a perfect understanding
+with Liu, and Ned cut it as short as possible, merely saying that Liu
+had recognized his name, having heard his associates mention it
+frequently. Then the Chinese boy had procured the disguise and Ned had
+stuffed out the shoulders of the coat to give it a better fit.
+
+"I was observed by a half a dozen men, some Americans, some Chinamen,
+while getting in here," Ned said, then, "but the disguise misled them.
+Now, the question is this: How are we going to get out?"
+
+"We'll have to fight our way out?" asked Jimmie.
+
+"It won't answer," Ned replied. "They are too many for us."
+
+Liu now came into the second cave and held up his hand for silence.
+
+"You'll have to hide in the back chamber," he said. "Chang is coming
+in."
+
+"I thought this was the back chamber," Jimmie said.
+
+"I suspect," Liu said, "that there's a chain of caves running through
+the divide. Come on!"
+
+Liu passed back to the west, removed a great box which stood against the
+rear wall, and disclosed an opening through which the patrol leader
+crawled. When the box was replaced Ned stopped and listened. What he
+heard was the click of a typewriter.
+
+
+
+
+CHAPTER XIII.--OFF ON A DESPERATE MISSION.
+
+
+What business calling for the use of a typewriter was being transacted
+under the main divide of the Rocky Mountains?
+
+Ned stood perfectly still in the darkness and listened. He could hear
+the click of the keys and nothing else. At length he moved stealthily
+forward over an even surface, feeling his way in order that he might not
+trip over some unseen obstruction and raise a racket in a tumble.
+
+Presently he came to a rug hanging at the end of the chamber in which he
+was. From the other side of the rug came a faint light. The noise of the
+keys was more distinct here, and the boy knew that he had at least
+located the operator.
+
+While he stood listening and undecided as to what course to pursue, the
+noise of the machine ceased and the operator--a young, well-dressed
+American--came toward him carrying a lighted candle in his hand. Ned
+crouched down in an angle of the wall and waited for him to pass.
+
+The boy was not quite so anxious now to leave the strange rendezvous in
+which he found himself. Some mischief greater than smuggling opium and
+Chinamen over the border might be carried on there. His work seemed to
+be growing on his hands!
+
+He had been sent to that district to investigate the cause of the
+frequent forest fires, and given an aeroplane in order that he might fly
+over the forests in making his observations. It seemed to him now, as he
+lay on his side against a wall of rock, waiting for the typist to pass
+with his light, that he was spending more time under the ground than in
+the air!
+
+The main range of the Rocky Mountains in the northern part of Montana is
+noted for its rugged and irregular formation. It is declared by some
+that the home of the original cave dwellers was here. Many of the great
+canyons are known to be honeycombed with openings almost large enough to
+hide a small city in.
+
+The typist moved straight ahead and his light disappeared from view.
+Then Ned advanced beyond the rug, which appeared to be of fine material,
+and flashed on his light. There was a table in the room, a couple of
+chairs, a row of pigeon-holes attached to the wall.
+
+On the table was a typewriter, in the pigeon-holes were folded papers,
+neatly ticketed and enclosed in rubber bands. Aside from the underground
+smell the place was tolerably comfortable. The air was damp and chilly,
+but Ned was well clothed and did not mind that.
+
+As has been said, the boy was now in no haste to leave the place. He
+believed that the mystery he had been sent out to solve would be solved
+there. For an hour or more he searched over the place, opening the
+folded papers and making a close examination of the typewriter and the
+stock of unused paper in the drawer of the table.
+
+At length, his examination completed, he passed back into the chamber
+behind the rug and listened at the opening through which he had entered.
+A sound of the steady beat of blows reached his ears at first, then a
+low whistle. That was Jimmie, he knew. The lad had a habit of whistling
+softly to himself, usually without time or tune.
+
+Waiting for a lull in the blows, he rapped softly on the box which
+backed up against the opening. Instantly the whistling ceased, and
+Jimmie's voice was heard.
+
+"Come on out," the boy said. "I've been kicking my heels against this
+box for an hour, waitin' for you to signal back."
+
+"Be sure there is no one watching," Ned cautioned.
+
+He heard Jimmie walking away, then heard him coming back. In a moment
+the box was drawn away from the opening.
+
+"You've been in there long enough to dig through to China," Jimmie said,
+as Ned stood by his side. "What did you find in there?"
+
+"A double keyboard typewriter," grinned Ned.
+
+"Quit your kiddin'," answered Jimmie. "You'll be claimin' next that you
+found a brass band in there."
+
+Ned did not stop to explain to the boy all that he had discovered in the
+inner chamber. His work there seemed to be finished now, and he was
+anxious to get back to camp. There was no knowing what had been going on
+there during his absence.
+
+"Where is Liu?" he asked.
+
+"Watchin' outside," was the reply. "He's my guard. Goin' to shoot me if
+I try to get away."
+
+"And the others?" asked Ned.
+
+"Don't know," replied Jimmie. "They herded a lot of Chinks an' went off
+down the valley."
+
+Liu now appeared in the entrance, bowed gravely to the boys, and stepped
+out on the ledge, with a Boy Scout challenge in the wave of his hand.
+
+"He's all right!" Jimmie said. "You ought to see the breakfast he got up
+for me. That feller can cook--an' then some!"
+
+"Call him," Ned suggested, "and we'll see if it is safe for me to go
+out."
+
+"For you to go out!" repeated Jimmie. "For us to go out."
+
+"I think you'd better remain here," Ned replied.
+
+Jimmie looked at his chum in amazement. The light back there was not
+good, but Ned saw several questions in the boy's eyes.
+
+"Liu can protect you, can't he?" Ned asked.
+
+"That's what I don't know," was the reply. "He will do his best, of
+course, but his best might not be good enough."
+
+Ned was thinking fast. If he permitted the boy to leave, the fact of his
+escape would be likely to scatter the outlaws--and he very much wished
+to keep them together for a short time.
+
+"I think," he said, "that we have found the men we want--with the goods.
+If you leave now they will make a quick getaway. You see that, don't
+you?"
+
+"Of course," was the reply. "An' I see, too, that if I remain I'm the
+one that's likely to make a quick getaway--to a country no one comes
+back from."
+
+"There may be some other way," Ned said, thoughtfully. "Give me a chance
+to think it over."
+
+"Oh, I'll stay, all right," Jimmie went on, "if it will do any good. I
+guess they won't eat me alive."
+
+As he spoke the boy put his hand to his eyes and gave them a long rub.
+
+"There's smoke in here," he said. "Don't you smell it?"
+
+"I was thinking of that," Ned replied, anxiously. "There may be a fire
+in the canyon."
+
+Regardless of consequences, Jimmie rushed to the ledge and looked out.
+The sun was no longer in sight, for a mist of smoke hung over the canyon
+and over the slope to the east.
+
+"There's goin' to be the biggest blaze ever!" Jimmie cried.
+
+Liu came to the side of the boys and pointed to the south.
+
+"The fire came through a gully over there," he said. "I was watching it
+from here. It was not put out yesterday, and worked its way over the
+divide. When it gets to going strong here no one can live in this
+cavern. I'm going to get out."
+
+"That's the idea!" Jimmie cried.
+
+The canyon was a veritable fire trap. For years the boughs and the turp
+of the trees had been dropping down. Ned knew that the blaze would mount
+to the cavern and be drawn into it. The atmosphere of the place
+indicated openings at the rear which would serve as chimneys.
+
+"Oh, the devils!" Jimmie cried. "To set a fire like that!"
+
+"They didn't set it, I tell you," insisted Liu, speaking as if in the
+defense of his employers.
+
+"Who did, then?" demanded Jimmie, half angrily.
+
+"It came through from the other side, just as I told you," replied Liu,
+with the utmost good nature. "There'll be a pass through the range some
+day where the fire found its way through."
+
+"But they set the fire on the other side," Jimmie urged. "They set it
+for the purpose of burning our aeroplane an' driving us out of the
+district. When we go out of the district they'll go with us, wearin'
+steel bracelets!" he added.
+
+"I rather think," Liu said, "that they set the fires over there to draw
+the foresters, away from this section, and so protect their business.
+That is what they have been doing right along."
+
+"Yes," Ned said, "there has been a forest fire for every cargo of opium,
+for every gang of Chinamen, that has been brought in over the border."
+
+"So that is the real trouble?" asked Jimmie. "How do you know so much
+about it?"
+
+Ned smiled and pointed to the slope to the east, where columns of fire
+were cutting their way through the timber.
+
+"It strikes me," he said, "that now is a pretty good time for us to get
+out of this. The outlaws won't come back so long as this danger exists,
+and we shall not be missed for a long time--or rather, Liu and Jimmie
+will not be missed."
+
+"They'll think we ran out to escape the heat and lost our lives in the
+fire," Liu said.
+
+Ned stood hesitatingly at the mouth of the cavern while Liu gathered a
+few articles he wanted to take with him.
+
+"If I thought the fire would reach the cave when the big trees in the
+canyon get to going," he mused, "I'd go back and get the papers--or more
+of them."
+
+"It surely will get into the cave," Liu said. "You see, the summit
+scoops down here quite a lot, and the timber line is almost to the top.
+The gulch below is quite high up on this elevation, still it is not so
+very high as compared with some of the summits to the north and south.
+So, you see, the timber line here is capable of getting up a good deal
+of a blaze, especially where the canyons are full of trees. The fire will
+come up here, all right."
+
+Ned darted away, was gone a minute or so, and returned with hands full
+of folded papers.
+
+"What you got?" demanded Jimmie.
+
+Ned laughed but made no satisfactory reply. After stowing the papers
+away in the numerous pockets of his borrowed suit, he led the way down
+the ledge, away from the cave he had first seen in his fall down the
+canyon, and which had proved so profitable to his search.
+
+The air was now filled with smoke. The canyon below was not yet in full
+flame, but a column of destruction was creeping upon it from the south.
+It seemed to Ned that there were numerous small fires, though how this
+could be true he could not understand.
+
+The boys made their way along the ledge without coming upon any of the
+men who had occupied the cavern. It was evident that the few left after
+the departure of the men with the Chinamen had fled before the clouds of
+smoke. The ledge wound up on the plateau from which Ned had dropped the
+night before, and here they paused to decide on some course of action.
+
+The light breeze was from the west, so the fires below were in a measure
+protected from it by the bulk of the summit, but Ned knew that the heat
+would in time bring the air into the burning spaces with a rush, merging
+the little blazes into one gigantic one which might repeat the disasters
+of August, 1910.
+
+Now and then, from far to the east, there came a signal in the shape of
+a gunshot. The faithful foresters were at work there, trying to head off
+the advancing flames before they passed beyond control. The place to
+combat a forest fire, of course, is ahead of it, and not where the red
+line is running through the sputtering timber.
+
+"If I could get the aeroplane," Ned said, as he looked over the country
+from the plateau, "I might get to the fighting line and do some good."
+
+"Where is it?" asked Liu.
+
+"At the camp."
+
+"The others won't dare bring it out, of course?" asked Liu.
+
+"Doubtful," Ned replied. "Frank has always taken a great interest in the
+machine, and was studying its mechanism when I left, but I don't think
+he will attempt to operate it. He ought not to, anyway."
+
+"If the men who left here to pinch the boys," Jimmie said, "showed up at
+the camp, an' Frank got a chance to mount the aeroplane, you bet your
+life he's shootin' through the air with it this minute, or hidin' in
+some valley."
+
+"But there were three of them," Ned urged, "and all couldn't ride."
+
+"They'd try!" gritted Jimmie, "unless Pat got cold feet an' run away."
+
+Ned glanced up at the sky, now very thick with smoke, as the boy spoke.
+He looked with indifference at first, then with interest, then with
+anxiety. There was a shape moving up there, coming slowly toward the
+plateau.
+
+"There they are!" shouted Jimmie, whose attention had been attracted to
+the sky by Ned's fixed gaze. "Frank's runnin' the machine. I'll bet
+dollars to apples that he'll dump her into the canyon when he tries to
+land here."
+
+The aeroplane, indeed, looked as if there were an uncertain hand at the
+helm. She wavered, tipped in the air currents, dipped wickedly, circled
+staggeringly, but finally swooped down on the plateau and, more by good
+luck than good handling, settled down within a dozen feet of the lip of
+the canyon. Frank and Jack were aboard. Pat, they said, had taken to his
+heels at the first suggestion of his joining the others in the ride.
+
+Ned examined the machine carefully and found it in excellent shape,
+although the gasoline was getting low.
+
+"Better go an' get some," Jimmie suggested.
+
+Ned looked toward the line of smoke off to the east.
+
+"We can reach the firing line with what we have," he said, in a moment,
+"and that may be sufficient for the present."
+
+"What you goin' to do?" demanded the boy.
+
+"Going to see if I can't help fight this fire," was the reply.
+
+"From here?" laughed Jack.
+
+Ned indicated a distant line of hills where the forest still stood green
+on the slopes.
+
+"We'll fight the fire from there," he said. "We can see the location
+well enough now, but the smoke will soon shut it out from here."
+
+"What can we do when we get there?" asked Jack. "We are safe enough
+here. The smoke and heat may scorch us a little, but we'll live through
+it, and that is more than we can say about the safety of the place you
+point out."
+
+"Pat will be making his way here," Ned said, "and you may as well remain
+here and meet him. I'll take Frank and go over to the place where the
+foresters are fighting the blaze."
+
+Jimmie was on his feet in an instant.
+
+"Me for the ride with you!" he shouted.
+
+"Some one may have to run the machine back," Ned said. "You can't do
+that, my little man, and Frank can, so Frank goes."
+
+"I don't see what you can do over there that the foresters can't do,"
+Liu said.
+
+"There is no knowing how useful the aeroplane may be," Ned said.
+
+Then the machine was rolled back as far up the plateau as possible, the
+boys took their seats, and then they were lost in the dense clouds of
+smoke in the sky.

+
+CHAPTER XIV.--THE BATTLE IN THE AIR.
+
+
+The smoke was driving fiercely through the green trees on the slope, and
+the line of fire was not far in the rear. Every moment the wind gained
+force, every minute the flames leaped higher and faster.
+
+The foresters felling trees and clearing a space at an advantageous
+point some distance in advance of the flames were working blindly,
+mechanically. The heat was intense, the smoke suffocating, irritating,
+blinding. The shirts of the workers were open at the throat, their coats
+had long ago been lost as they had been beaten back from one stand to
+another.
+
+Now and then a worker dropped senseless in his tracks, his lips cracked
+with the heat, his face blistered, his tongue lolling from his smarting
+mouth like that of an overworked horse. Then the men who were able to
+move and understand would carry him back to a spot of supposed safety
+and return to re-engage in the almost hopeless fight, the battle which
+the flames were winning in every charge and sally.
+
+The aeroplane, after a narrow escape from destruction, landed on a
+little rise of ground back of the working line when the wind lulled for
+an instant, and hope shone in the faces of the astonished men who
+gathered about to greet the unexpected arrivals.
+
+"We can master it," Green, the leader, said, after many questions had
+been asked and answered, "if we can be supplied with water. We wasted
+our supply wetting our clothes a long time ago, and are suffering."
+
+"Get us water," shouted another, "and we'll win yet."
+
+"There's a spring three miles away," Green went on, speaking in Ned's
+ear, for the roaring of the flames drowned all ordinary conversation.
+"If you can take our water bottles there and fill them we can beat this
+blaze. If you can't we've got to retreat and let the whole district burn
+over."
+
+"I have very little gasoline," Ned replied, "but I'll try."
+
+"We sent two men out not long ago," Green continued, thrusting his
+scorched face close to the boy's. "We sent them out with water bags, but
+there are no trails, and It will take them hours to make the spring and
+return. With your aeroplane you ought to do it within half an hour."
+
+"Fire fighters marooned without a supply of water, or a trail cut to a
+spring!" shouted Frank, scornfully. "Great head some one in authority
+has!"
+
+"There are no trails, no telephones, no horses!" cried Green. "It looks
+as if the government sent us here to die. Hurry up with that water."
+
+"If the gasoline holds out," Ned said, loading a dozen water bags on the
+machine, "I'll be back here in less than half an hour, bar accidents."
+
+"There is plenty of gasoline back there in the shanty," cried Green. "We
+have been using it lately in starting back fires, but the wind is now
+too strong for that. Get a move on, and take all you want."
+
+In a short space of time, but not without great risk, the tanks of the
+aeroplane were filled, and then Ned took in the general situation in the
+sky. The wind was blowing in puffs, but it was certain that a miniature
+tornado was at hand. He thought he could reach the spring, which had
+been described as lying to the southeast, but was not certain that he
+could make his way back.
+
+He believed, however, that by flying either very low or very high up, so
+as to get all the protection possible from the mountain, or escape the
+sweep of wind just above the fire, he might be able to bring in one load
+of water before the worst of the wind storm came. He knew that it was an
+almost unheard of thing to even try to navigate the air in such a gale,
+but human lives were at stake, and he decided to try.
+
+"You'll have to help me up against this wind," Ned said to Green. "If I
+start with the air current I'll be carried too far to the east before my
+power begins to become effective. If I can hold my own against the wind
+until I get above the smoke I think I can win the game."
+
+It was a desperate expedient, but it appeared to be the only possible
+one. If the men had water they might succeed in stopping the fire and
+saving millions of dollars worth of timber. If the fire gained the upper
+hand they might lose their lives. The men cleared and smoothed a path
+for the run of the wheels, by great exertion sent the machine along at
+good speed, and then stood and watched it with anxiety depicted in their
+faces.
+
+The great white bird quivered in the face of the wind, but the motors
+were true to their duty and the rudder held. To turn about in the face
+of that rush would be impossible, so Ned worked his levers guardedly and
+kept the wings as level as he could. Now and then a swirl of heated air
+would shake the hopes of those watching below, but in the end the
+aeroplane drifted slowly ahead, up, higher up, and was lost in the
+smoke.
+
+"The lad is worth his weight in gold!" shouted Green. "He'll do it! I
+know he'll do it!"
+
+"Powerful motor," one of the foresters said. "When we saw the machine
+last she was actually holding her own against the wind."
+
+This was, indeed, the fact, but the wind was not as strong in the higher
+levels as at the upper limit of the heat from the fires. A great fire
+usually brings a great wind, as those who witnessed the burning of
+Chicago and San Francisco well know. The hot air rises, forming a
+partial vacuum, and the colder air rushes in.
+
+Ned and Frank gained the spring, filled their water bags and started
+back. It was no easy task to land near the spring in that whirl of wind,
+nor yet an easy task to get the aeroplane into the air again, but the
+feats were accomplished. Often after that exciting day the boys declared
+that they had no idea how they ever did it.
+
+"We were excited," Frank would say, "and took chances, everything worked
+in our favor, and we loaded the water. We knew that lives were at stake,
+and it seemed that we had the strength of a score of men, and the cool
+heads of men far beyond all excitement. I never saw anything like the
+way Ned handled the levers. The wings and the rudders seemed to me to
+work on a brain suggestion rather than on a movement of the levers."
+
+But the most difficult part of the journey still remained to be
+accomplished after the water had been secured. The 'plane was much
+heavier and did not respond so readily to the hand of the driver, and
+the return course was quartering against the wind. Ned, however, did not
+attempt to move directly toward the destination he sought.
+
+Instead he sailed off to the south, working west as much as possible. He
+tacked as a yacht tacks in the wind and came near upsetting several
+times. He found it impossible to sail low on account of the eddies and
+currents created by the heat, and so lifted the machine far up into the
+air. It was better sailing there, and he managed to get as far west as
+he thought necessary.
+
+But he could not see the landing place. Below was an ocean of smoke, the
+waves heaving in the touch of the wind, the edges now and then tipped
+with flame. Above the sun smiled at him, and the birds flew excitedly
+about, peering down at the threatening roll of clouds.
+
+"I'm afraid," Frank said, grasping an upright and clinging to the water
+bags.
+
+"I never was so frightened in my life," Ned called back, lifting his
+voice so that it might be heard above the snapping of the motors.
+
+"I didn't finish," Frank called back, his heart thumping loudly. "I
+wanted to say that I was afraid we'd sweep past the workers when we
+descended into the smoke and the swifter breeze near the earth."
+
+"I said just what I wanted to say," Ned answered. "I never was half so
+scared in all my life."
+
+Yet his hand on the lever was steady, his brain was as cool as if he had
+been sitting in the Wolf Patrol club room in New York. He knew that the
+dip of a wing a foot lower than he intended might send them both into
+the blazing forest below. He was afraid, but not with a shrinking,
+physical fear, but afraid because he understood the peril he was
+in--because he knew that upon his efforts depended the lives of the
+heroes in the heated hell below.
+
+"We've got to go into that mess of smoke, I suppose?" shouted Frank.
+
+"There is no other way," Ned called back. "We've got to dip down low
+enough to see the line of fire and take our chances on landing where the
+fighters are. You understand that they are farther to the east than when
+we left them?"
+
+"Of course they have been driven back," Frank said. "I never thought of
+that. We may not be able to find them at all."
+
+Ned shut his teeth and settled his jaw.
+
+"We've got to find them," he said.
+
+A long, sullen roaring, like the beating of waves on a beach in a storm,
+now reached the boys' ears, even shutting out the chattering of the
+motors. It came from the west, and passed along, as it seemed, below the
+level held by the aeroplane, now high up in the air.
+
+"If we don't get down there pretty soon," Ned said, shouting, "we will
+be too late. That wind will join the different fires and make one
+roaring mass of the whole northwest. I wish I knew just how far the
+foresters have been driven back."
+
+"Do you know where to look for them, north or south?" asked Frank.
+
+"There is a peak to the west and one to the east," was the reply. "They
+are on a line with the two. But the trouble is that we can't see the
+peaks after we drop down into the smoke."
+
+"There appears to be a little lull in the wind now," Frank said,
+shutting his lips tight, as a man does when about to make a sudden
+plunge into unknown waters.
+
+The remark was suggestive. Ned knew by it that his chum had braced
+himself for the dash.
+
+"Here we go, then," Ned replied. "Remember that we'll go about eighty
+miles an hour when I turn the motor on full head, and that we can't be
+more than five miles from the spot where we left them, so keep your eyes
+out."
+
+The aeroplane dipped gracefully as Ned touched the lever. In a minute
+the boys were surrounded by smoke. It was hot smoke, too, and made
+breathing difficult. Their eyes smarted until their faces were wet with
+nature's protest against such irritation of the organs of sight. The
+chuck-chuck, snap-snap of the motors was in their ears, the seats they
+occupied--frail rests between life and death--shivered under the
+pulsations of the machine.
+
+Now and then the aeroplane dipped frightfully, but the wings and the
+rudders brought it back again.
+
+"Can you see the earth yet?" asked Frank, In an awed tone, which sounded
+like a whisper in that clatter.
+
+"We seem to be over the fire," Ned returned.
+
+And that was all. There was no need of conversation. In all their lives
+they would never be so near to a frightful death as they were then.
+
+First they caught sight of a rocky ridge. Ned knew where that was, and
+realized that he was still in the direct line of the workers. Beyond
+this ridge, he knew, was a valley, so he must drop down. The workers
+were on a level beyond the valley, a great plain of fir and pine between
+gigantic ranges of the Rocky Mountains.
+
+The aeroplane trembled as she dropped, swiftly, apparently straight
+down. Frank grasped his upright and prepared to spring out of the
+wreckage when it fell, if there was anything to fall from after the
+trees had had their way with the frail machine.
+
+The smoke was blinding. Nothing could be seen but smoke for a time. Then
+the dark gray clouds turned red, and Ned knew that he was nearing the
+advance line of the fire, and that it was mounting to the very tops of
+the giant trees on the plain--or elevated plateau, rather, for, though
+comparatively smooth of surface and heavily timbered, it was far above
+sea level.
+
+If you look on an enlarged map of northern Montana you will see that the
+Rocky Mountains do not consist of one great, massive range. There are
+ridges and valleys, and plateaus extending for hundreds of miles along
+the British frontier. There are peaks from which the snow never
+disappears, and there are timber lines which crawl almost to the summit
+of other peaks. There are fertile valleys where cattle grow fat, and
+great gorges where beasts of prey await their victims in thickets.
+
+It is the timber on this great stretch of country that the United States
+government is trying to save.
+
+The heat was blistering now, and Ned feared for the safety of his
+gasoline tanks. At a motion from him Frank removed his coat, carefully,
+for a slight movement in the air is sometimes productive of disastrous
+results, placed it over the tanks, after a great effort, and managed to
+saturate it with water from one of the bags.
+
+Through the smoke a line of tree tops now came into view, low down, and
+the boys knew that they had passed the fire line. Ned tried to slow
+down, but found that he must keep the motors going in order to retain
+control of the machine.
+
+"There's a clear space ahead!" Frank shouted, and Ned dropped. Then a
+giant trunk obtruded itself, and the boy tried to dip and whirl so as to
+dodge it, but the pressure of the wind was too strong.
+
+The machine headed straight for the tree, which seemed to Frank to be
+about a thousand feet high.
+
+"Hang on to the first thing that comes to your hands if she strikes!"
+Ned shouted. "But stick to the 'plane as long as she is clear. There may
+be a current of air which will sweep us away from that tree."
+
+"Here's hoping!" Frank gasped back, and then the smoke shut out the
+view, making the situation doubly dangerous.
+
+
+
+
+CHAPTER XV.--TOLD BY THE FOREST RANGER.
+
+
+The rangers, almost exhausted, were fighting the fire desperately,
+hoping against hope, when the cyclone--it amounted at times almost to
+that--struck the forest. Then they knew that the fight was lost for the
+time being.
+
+It was now a question of escaping from the flames they had been battling
+with. The chief foresters knew very well that there was a way to safety,
+but they had under their command many rangers who had joined the service
+merely for the adventures they anticipated meeting, and these, they
+understood, would be hard to manage.
+
+When the order came to drop everything and fall back some of the new men
+accused those in authority of cowardice and kept on in the course mapped
+out for them under entirely different conditions. Two of them even
+insisted on starting back to the rough shanty and preparing dinner. They
+lost their way in the blazing inferno, and their bones were found two
+weeks later, at the foot of a tree which had been burned into a stub,
+but which had not fallen.
+
+When the danger became apparent to Green who was in charge of the
+company found by Nestor, he ordered his men into a "burn" of half a
+dozen acres in extent. By "burn" is meant a patch of forest which has
+been cleared by fire the previous year. This "burn" was entirely
+stripped of trees. The fire had done its work well, but had been checked
+before spreading.
+
+The men could hear trees falling as they dashed along. The fire was
+screaming, the wind whistling and roaring. Coals of fire, driven like
+arrows by the wind, hit the men in the back as they rushed toward
+safety. At last the "burn" was gained, and the men threw themselves face
+down on the ground. At the eastern edge there were large logs which had
+not been entirely consumed, and some of the men lay down behind them.
+
+The air was so hot that it cut the lungs like acid. Above, across the
+old "burn," streamed a river of flame, now racing like a mountain
+torrent, now dropping sullenly back to the west, like a fiery ceiling
+which had been rolled away. On such occasions the fainting foresters
+below could catch a breath of fresh air and a hazy view of the sky.
+
+Some of the men, half crazed by their sufferings, arose to their feet
+and shook clenched hands at the blazing forests, at the brassy sky, and
+the green hills away to the east. Green crept from one to another and
+whispered that the only hope of life lay in keeping on the ground.
+
+Once when he was creeping toward a man who was moaning in anguish and
+despair he turned his eyes upward to the sky, clear for an instant, for
+the wind was wayward after a time, and saw a speck sweeping out of the
+west, dropping lower and lower, whirling in the wind, racing like an
+express train.
+
+"Dan," he whispered to the man he was trying to comfort, "get a brace!
+There's no use of giving up now. Why, man, the fight is won, and Nestor
+is coming back with water!"
+
+"Impossible!" grunted the other. "Impossible--in this wind!"
+
+"Then look," Green said.
+
+A sheet of flame swept over the "burn," lay upon it for an instant like
+a red-hot roof, and then warped and twisted itself away.
+
+"I see," Dan said, looking into the sky again, "but he can't land.
+Impossible--in this storm!"
+
+"Wait and see!" Green said, and sank back to the earth.
+
+The aeroplane circled, high up, like a bird seeking its prey in the
+burning forest. The wind was tolerably steady at that height, but Ned
+knew that when he came into the lower current he would meet conditions
+which he could not understand.
+
+"There's a place to drop!" Frank shouted to him, pointing ahead to the
+"burn," which seemed only a few yards away.
+
+The aeroplane had missed the tree which had threatened it by an inch,
+and had turned upward again, for there were other trees in the way of a
+descent there. The "burn" was the first free spot that had been
+observed, and, besides, it lay inside the line Ned had figured as
+leading to the foresters.
+
+"Hang on!" Ned cried.
+
+The aeroplane plunged down, almost vertically, and Frank felt as if he
+was standing on his head.
+
+"Don't jump when it strikes the ground," Ned commanded.
+
+Watched by a score of anxious eyes--for the foresters under Green had
+all been told of the coming relief--the aeroplane shot down, struck the
+ground at the center of the "burn," rolled swiftly for a few yards, and
+stopped. At that moment the space above filled with flame.
+
+Both boys threw themselves on the ground and waited. When the fierce
+gust was over the men gathered about them eagerly.
+
+"Did you make it?" asked Green.
+
+"Yes," Ned replied. "Get the bags out and distribute the water. Don't
+let the men waste it."
+
+"I'll see to that," cried Green.
+
+Without the water, without the cooling sips, without the wet cloths held
+over nose and mouth, without the saturated sponges laid on scorched
+heads, the men would have died there in the forest. Presently, when the
+consumption of the timber to the west reduced the heat, when the wind
+quieted down in a measure, they were ready for another fight with the
+flames, and it was owing largely to their exertions that the fire was
+extinguished before millions of acres had been burned over.
+
+"It is a dream!" Green exclaimed, that afternoon, as he stood by Ned and
+the aeroplane. "I don't believe yet that you did it."
+
+"I don't see how I did," laughed Ned. "Anyhow, I'm sure I couldn't do it
+again. I guess Providence took the matter into his own hands. Honestly,
+I do not believe any human strength or skill could do what was done with
+the aeroplane to-day. It was a miracle."
+
+"I know of a nervy boy who had something to do with the miracle," said
+Green.
+
+Ned was naturally anxious regarding Pat, Jack and Jimmie, but believed
+they would show up in good form whenever he got back to the vicinity of
+the place where they had been left. When the boys were in camp with the
+rangers that night, Ned asked Frank about Pat's idea of safety after
+refusing to go up in the aeroplane.
+
+"He said he would stay about the valley," Frank replied. "There is
+plenty of provisions there, you know, and Pat is quite long on the
+eats," he added, with a laugh.
+
+"And Jack and Jimmie will be sure to hang about the neighborhood of the
+caves," Ned said. "The Chinese boy, Liu, will be able to care for them.
+If there is enough gasoline in the tanks, I may go back to the valley
+to-night."
+
+"You'd better get some sleep to-night," Frank advised. "I don't know how
+long it has been since you settled down for a night of it. If you keep
+your brain working right you've got to sleep."
+
+"I really ought to go to San Francisco," was the astonishing reply to
+this advice. "I have work to do there."
+
+"What work?" demanded Frank.
+
+"You see," Ned answered, "we have done nothing yet, except discover a
+crime with which we are supposed to have nothing to do. We have brought
+a little water for the fire-fighters, but we came here for a certain
+purpose, and we have not made good as yet. Perhaps, when I get to
+Frisco, I can hunch my wits, as the baseball fans say, and report good
+progress."
+
+"I don't understand what you mean," Frank said.
+
+"I am not sufficiently sure of my ground to attempt an explanation now,"
+Ned replied.
+
+"Of course," Frank said, thoughtfully, "there's the murder case you went
+to Frisco about before. You might look that up again, but I can't see
+where that has any bearing on this forest fire business."
+
+"You may be surprised," Ned said, "when the end comes. Somehow, I have
+an idea that the two crimes dovetail into each other."
+
+"Nothing stirring!" laughed Frank. "They don't seem to me to match.
+Still, you may have information I do not possess."
+
+An hour later, after the not very elaborate supper had been eaten, Green
+came to the little tent which had been set aside for Ned and Frank. He
+had not wholly escaped the dangers of the day unscathed. There were
+burns on his hands and face, and one of his feet was bandaged.
+
+"Shoe burned through," he said, shortly. "I shall have to walk with a
+crutch for several days."
+
+"You won't like that," Ned suggested.
+
+"No, indeed," was the reply, "especially as I would like to be moving
+about in order to see what has happened to the other boys."
+
+"Have you heard from any of the other groups?" asked Ned.
+
+"Howard came in from the north," was the reply. "Three men killed up
+there. The fire caught them unawares. One of my men has gone south, but
+it will be some hours before I hear from him."
+
+"I am afraid there were several lives lost," Ned said. "In the morning
+I'll fly about and see what I can learn."
+
+"What I came here to talk about," Green said, after a pause, "is this. I
+want to know what you think of the Chinks?"
+
+"The Chinese fire-fighters?" asked Ned.
+
+Green laughed quietly for a moment before replying. Then:
+
+"They told you that, did they?"
+
+Ned nodded. He wanted to jump into the subject without waiting for Green
+to have his say, for he was greatly interested, but prudence told him to
+listen to the forester first.
+
+"Yes," he said. "They told me that."
+
+"Also that they were foresters--the men who told the story about the
+Chinks, I mean?"
+
+"Yes, one of them claimed to be in charge of this district."
+
+"Well, you know better than that now, so there is no use in talking
+about that. You saw some of the Chinks?"
+
+"Certainly. I even had the honor of visiting their residence."
+
+Frank laughed, wondering what sort of a story Ned would have to tell him
+when they were alone again.
+
+"It is a wonder you ever got out again," Green said.
+
+"I left under the excitement of the fire," Ned said. "It was easy
+enough."
+
+"Do you know where the Chinks have gone?" asked Green.
+
+"I think I do," was the reply.
+
+"To San Francisco?"
+
+"Yes, some of them. Others to Portland, I think."
+
+"Smuggled in?"
+
+"Of course, though it seems odd that they should want to cross the
+border so far away from civilization. It must be expensive getting them
+in over such a route."
+
+"The men at the bottom of the game are watched," Green said. "Watched so
+closely that they are obliged to keep out of the actual work and do
+their business through unsuspected channels. After this place has been
+raided they will try some other point."
+
+"You know what has been going on then?" asked Ned, surprised that the
+matter, as understood by the forester, had not been reported to him by
+the Secret Service man in San Francisco.
+
+"Yes," was the reply.
+
+"And you have reported to your superior officers?"
+
+Green nodded, and Ned began to feel provoked at the strange attitude
+taken by the government in the matter. Surely he should have been posted
+as to conditions in the district before being sent on.
+
+"Why wasn't I informed of this new element in the case?" he asked.
+
+"Well," Green replied, "the officials have an idea that the men who are
+running the Chinks and the opium in are the men who are responsible for
+the forest fires. In fact, I have so reported to them for a long time."
+
+"Go on," the puzzled boy requested.
+
+"You see," Green continued, "I might go and pick up a couple of dozen
+Chinks almost any month, and capture a lot of opium, and arrest a few
+men caught with the goods on, but, don't you see, that wouldn't end the
+game?"
+
+"I see that," Ned answered.
+
+"There is a man at the head of this game who is working from behind the
+scenes somewhere," Green hastened to say. "I don't know who he is. The
+officials at San Francisco don't know who he is, or where he is. The big
+guns at Washington know just about as much regarding the head center of
+the game as we do. Well, that is what you were sent here for--to get
+down to cases, as I used to say on South Clark street, Chicago."
+
+"It was thoughtful of them not to interrupt the game until I got here,"
+Ned said.
+
+"Yes, I thought so," Green went on. "I thought that any man, or boy,
+coming here to get to the bottom of this thing would want us to leave a
+few ropes hanging out for him to climb down. You found 'em."
+
+"Yes, I found them," Ned replied. "I found the counterfeit foresters and
+the Chinks, as you call them, and I found something else."
+
+"That is what we expected you would do," Green said, after a moment's
+hesitation. "We wanted you to begin without pointers, with a brain free
+of all the unsuccessful schemes which have been worked. You see, I know
+a great deal about it, my boy," he added with a laugh. "I knew, days
+ago, that you would be here. When I saw the aeroplane in the sky I knew
+who was in charge of it."
+
+"What is the next move?" asked the boy.
+
+"That is for you to say," was the reply. "I am under orders to follow
+any reasonable instructions from you. It is for you to suggest
+something."
+
+"Well," Ned said, "that brings me to a point I was studying over when
+you came in. I was wondering if you would detail men to do certain
+things for me."
+
+"Sure I will. If Washington has confidence enough in you to put you in
+charge of the blindest case in history, why shouldn't I have equal
+confidence in you? You bet I'll be there with the oxen when you give the
+word."
+
+"I thank you," Ned replied. "What I want now is men enough to guard two
+points. One is a cave near Lake Kintla, and the other is the cavern
+where the Chinese have been hiding."
+
+"How many men?" asked Green.
+
+"Two to each place. If there is need of more, others should be ready to
+assist."
+
+"I wish you all success," Green said, after the details of the
+surveillance had been arranged. "We have located the tools, and now it
+is for you to let down to bed rock. The government wants the headpiece
+of this game, and believes that you can put your finger on him. Half a
+dozen inspectors have failed, but I have faith in you, boy."
+
+"Well," Ned replied, "I am glad of your confidence, and thankful for the
+help you promise, and will only say that the man behind the scenes will
+soon be brought out. I think I know his 'cue'!" he added, with a laugh.
+
+"Already?" asked Green.
+
+"I am only expressing confidence in the clues I now hold," Ned said in
+reply. "It may be that the next clues I find will point the other way."
+
+Green shook hands with the boys and went to his tent. It was a clear
+night up above the mountain tops, but down where the boys were the smoke
+of consumed forests lay on the ground like the gray ghost of fallen
+trees. Off to the west the summit of the Rocky Mountains--or one of the
+summits--lifted itself above the smudge, standing like a giant up to his
+neck in gray dust.
+
+"Over there," Frank said, "is Pat--hungry, if you want to know, and
+nearer are Jack and Jimmie. I wish we could hear from them."
+
+"If the ground wasn't still red hot back there," Ned said, "Jimmie would
+be sure to find us."
+
+"By the way," Frank said, presently, "what did you mean when you told
+Green that you had a 'cue' which would bring out the man behind the
+scenes?"
+
+"I meant that I have blundered on a clue which promises well," was the
+reply. "And now," he said, yawning, "I'm going to bed. Rather warm, but
+I think I'll sleep, all right."
+
+In five minutes Ned was sound asleep and Frank was about to lie down by
+his side when Green made his appearance. The forester noted the sleeping
+boy and laid a finger on his lips.
+
+"Let him sleep," he said. "And come out here and see if you know
+anything about the fellow that is tampering with the aeroplane."
+
+"What is he doing to it?" whispered Frank.
+
+"Acts like he was preparing to take a trip in it," was the reply.
+
+The words were followed by the rattle of the motors.
+
+
+
+
+CHAPTER XVI.--HOW A CAT TREED A WOLF.
+
+
+Smoke still hung over the "burn." Now and then it was swept aside by a
+gust of wind which seemed now to blow out of the east, and so did not
+come sizzling with the heat of burned forests. The general effect,
+however, was that of a heavy, stifling fog, and Green and Frank crept
+along toward the aeroplane with their hands held out before their faces.
+
+The clatter of the motors had ceased, but the tap-tap of steel on steel
+was faintly heard as they neared the machine. Occasionally the worker,
+whoever he was, ceased his tapping, as if listening.
+
+"He's got his nerve with him," Frank whispered, as they moved along.
+
+"How did he get here?" asked Green. "That is the question that is
+troubling me."
+
+Presently the two came up so that the figure of the man could be
+discerned, standing before the bulk of the planes. Green sprang forward
+and seized him by the arm. For an instant it seemed as if the capture
+would be made without a struggle, then a shot was fired and a crouching
+figure leaped away.
+
+Frank saw the forester fall and leaped toward the retreating figure. The
+race in the darkness, caused by the pall of smoke which followed, was
+short, for Frank was a noted runner and soon overhauled the fugitive. He
+did not attempt to take hold of the man as he came up. He knew that such
+a course might mean an unequal contest, for he was only a boy.
+
+Instead, he dropped to the ground and caught one of the runner's ankles
+in both hands. Naturally the fellow plunged to the ground head-first. He
+turned quickly and leveled a revolver. There was no warning. The shot
+came instantly, the bullet passing over the boy's head as he dropped
+upon the prostrate figure.
+
+With the hand which held the weapon held closely to the ground, Frank
+struggled with the fellow for an instant, filling the heavy air with his
+cries for assistance. The first shot had been heard by the sleepers, and
+help was at hand immediately. The captive was neatly tied by the light
+of Frank's flashlight, and the foresters gathered about, still rubbing
+their eyes.
+
+The "burn" was not all in darkness all the time, for the glare of the
+smouldering embers to the west lighted the place fairly well. Only for
+the smoke the ruddy light would have made a pretty good illumination.
+When the fellow was lifted to his feet an exclamation of astonishment
+came from the group about him.
+
+"Sawyer!" some one cried.
+
+The prisoner dropped his chin for a moment, as if studying out some
+difficult proposition, then faced the others sheepishly.
+
+"I thought I could get away with it," he said.
+
+A cry now came from the men who had hastened to Green's assistance.
+
+"He's dead, I guess," the voice said.
+
+"I didn't shoot to kill," Sawyer exclaimed. "He can't be dead."
+
+"Why did you shoot at all?" demanded one of the rangers, approaching
+Sawyer with threatening fists.
+
+"He was in my way," was the sullen reply. "I have always wanted an
+aeroplane, and I thought this a good time to get one."
+
+"Did you injure the machine in any way?" asked Frank, as Sawyer stood
+gazing furtively from face to face, his black eyes showing fear.
+
+"When I found I couldn't get it off," was the reply, "I loosened some of
+the burrs. It can be repaired easily enough."
+
+"That is more than can be said for you, if you have killed Green," one
+of the men declared, shaking a fist at the prisoner. "If he's dead
+you'll be hauled up on one of these trees."
+
+"You wouldn't dare do that!" Sawyer cried.
+
+"Wouldn't we?" cried the other. "You'll see when we know whether he will
+live or not. How is it, boys?" he continued, stepping toward the spot
+where Green lay.
+
+The man bending over Green was about to reply when Nestor laid a hand on
+his arm. The boy had been awakened at the first shot and had slipped out
+of his tent and over to the side of the wounded man, being the first to
+arrive there.
+
+"Wait," he said, as the ranger looked up in surprise. "Green is not
+seriously injured," Ned went on, "but I want to make that rascal think
+he is."
+
+"What's the idea?" asked the other, glancing from face to face about
+him.
+
+"When he stands under a tree with a rope about his neck," Ned said,
+"he'll tell us the truth about this affair."
+
+"He was trying to steal the machine," the other said.
+
+"Green has a bullet hole through his shoulder," Ned said, "but I want
+you to treat the prisoner as if the shot had been fatal. Kindly carry
+him to his tent."
+
+The command was instantly obeyed, for the foresters all knew why Ned was
+there, and understood that he was the personal representative of the
+Secret Service chief at Washington. Ned then called Frank aside and
+spoke a few words in a whisper. The boy grinned and hastened back to the
+group about Sawyer.
+
+"Nestor wants to talk with Sawyer," he explained, "and wants me to take
+him to his tent."
+
+"We'll take him to Nestor's tent after we get done with him," declared a
+burly forester whose face bore many evidences of the hard fight he had
+made during the fire. "It won't take us long to settle with him."
+
+Frank spoke a few words to the man and he was one of the first to push
+the prisoner toward Nestor's tent.
+
+"If you'll keep those men off me," were Sawyer's first words, "I'll tell
+you what you want to know. They mean to kill me."
+
+"I think there is little doubt about that," was Ned's reply. "Why did
+you want the aeroplane?"
+
+"If you must know," was the reply, "I was sent here to get it, or to
+wreck it so you couldn't use it."
+
+This looked promising, and Ned waved a hand at Frank.
+
+"Throw him out here!" came a gruff voice from the crowd.
+
+"I won't tell," Sawyer went on, "unless you promise to keep them away
+from me. I didn't mean to kill Green, and no court will convict me."
+
+"When did you come here?" asked Ned.
+
+"A month ago," was the reply. "The day you landed in San Francisco a man
+came to my boarding house and employed me."
+
+"He mentioned the aeroplane?"
+
+"Yes, he knew all about it."
+
+"Treachery in the Secret Service, eh?" asked Ned.
+
+"I don't know how he gained his information," was the reply. "He told me
+that he had secured a job for me in the forest service, and that I was
+to join the crew in this district."
+
+"And steal the aeroplane?"
+
+"Steal it or wreck it. There are men with the other crews. You would
+have found an enemy wherever you landed."
+
+This was all very amazing, and Ned wondered how many pitfalls had been
+set for him in San Francisco. He had no doubt that Sawyer was telling
+the truth. The question was as to whether he would tell the story as it
+was from that point on.
+
+"Who was it that engaged you--gave you your instructions?" he asked.
+
+"I don't know," was the reply.
+
+Ned swung his hand again, and a fierce demand that the prisoner should
+be thrown out arose from the group outside. Sawyer shivered and crept
+out of his camp-chair to Nestor's side. His face was deadly pale, being
+sheltered from the ruddy glow of the fires. Just where the men stood
+outside lay a red lance of light, giving a demon-like look to their
+rugged faces.
+
+"If you don't tell me the truth," Ned said, "I can't protect you."
+
+"I tell you I don't know," wailed the frightened man. "I had never seen
+him before. I wanted a job and took what he offered. I didn't think it
+would be so great a crime to steal or wreck an aeroplane."
+
+"What were you to receive for the job?"
+
+"One thousand dollars."
+
+"Hurry up! Throw that sneak out!"
+
+Sawyer, like the coward he was, threw himself down on the floor of the
+tent and groveled at Ned's feet.
+
+"You would know the man again?" asked Ned.
+
+"Yes; I can pick him out of a score of men."
+
+"You will do this willingly?"
+
+"Yes; I'm sick of the whole game. I didn't mean to hurt Green. I wanted
+to scare him away so I could get back to my tent without being
+recognized. That is all I wanted, and I did not mean to hit him at all."
+
+There was a great deal more talk between the two. Ned soon became
+convinced that Sawyer was a weak man, morally and intellectually, who
+would be apt to follow the lead of one stronger than himself.
+
+After Ned had left a guard over the man and visited Green--who was doing
+very well, and laughing over the trick the boy had played on Sawyer--he
+went back to his rough bed, well satisfied with the events of the night.
+
+"By the way," Frank said, crawling into the tent after assisting in
+caring for the wounded man, "I don't understand what you mean by saying
+that you've got a clue which you think will force the man behind the
+scenes out on the stage, in full view of the audience. If there is such
+a clue hovering about I haven't become acquainted with it."
+
+"The clue is hardly well enough advanced to talk about," Ned replied.
+
+"But if you've got a line on the leader of this bunch you've won the
+case," suggested Frank.
+
+"That is what the government sent me here for," Ned replied. "The chief
+of the Secret Service expects me to round up the man responsible for the
+frequent forest fires. I think now that he should have told me that
+smuggling was going on up here, but he may have had a good reason for
+not doing so."
+
+"You know what Mr. Green said," Frank interrupted. "He said the
+government officers wanted you to take the case and find out everything
+for yourself. Perhaps they feared that you would pay too much attention
+to these smugglers, and let the forest fires issue go with scant
+investigation. They might have arrested the smugglers at any time, you
+know."
+
+"Perhaps so," Ned replied, "But that wouldn't have brought the manager
+of the unlawful enterprises into the hands of the law. After all, the
+Secret Service men may have been right in sending me up here without
+instructions or special information. What a laugh they would have had if
+I had failed to discover the Chinamen and the opium."
+
+"Perhaps they wanted to see if you would discover them," laughed Frank.
+"Have you any idea," he added, "that the Secret Service men knew that
+you would be followed in here--that the plans of the government
+regarding your work were known to the outlaws? Do you think they knew of
+the employment of Sawyer and the others by the men at the head of the
+conspiracy?"
+
+"No; I hardly think the man who gave me final orders at San Francisco
+knew that all he did was known to the men he was fighting," Ned replied.
+"The head of the bunch put a good one over on him there."
+
+"And came near putting one over on you, also," grinned Frank. "The
+aeroplane has been attacked twice already, and others are doubtless
+waiting to get a crack at it."
+
+"They will have to hurry up if they do," Ned said, with a chuckle, "and
+you will have to look out for yourself if they succeed, for I'm going to
+have you take me to Missoula in the morning and then go back and collect
+the boys."
+
+"And not come back here again?" asked Frank.
+
+"Not unless we come back for a pleasure trip," was the reply.
+
+"Well," Frank said, "that pleasure trip idea looks pretty good to me.
+Why not?"
+
+"I may have time," Ned replied.
+
+Frank threw himself on the blankets which had been provided by Mr. Green
+and closed his eyes, which were still smarting from the effects of the
+smoke.
+
+"If you go away to-morrow," he said, presently, "what is to become of
+the clues we found in the cavern by the lake?"
+
+"All provided for," Ned answered.
+
+"And all the Chinks, and everything you discovered while visiting them
+in the caves almost under the divide?"
+
+"Everything provided for," Ned said, sleepily.
+
+"And you think you can close this case by going to San Francisco?"
+demanded Frank, a touch of sarcasm in his tone.
+
+"Go to sleep, little boy," said Ned, in a tantalizing tone.
+
+"But do you?" insisted the boy.
+
+"Of course I do," was the muttered reply. "Go to sleep, little man!"
+
+And Frank tried to obey, but sleep would not come. The fire still
+smouldered over in the west. The ruddy light of the embers was still
+touching the camp with its red fingers. The smoke was still asserting
+itself in the air. The puzzle was still there!
+
+After the boy had rolled over at least fifty times, and arose to consult
+a water bag at least a dozen times, he seated himself under the flap of
+the tent and looked out. There was a moon now, and the smoke only half
+hid it. Far off in the woods wild creatures were expressing their
+opinion of the fire and the wanton destruction of their homes. There was
+a faint rustle in the foliage of the trees east of the "burn."
+
+"Gee!" the boy muttered. "I'd like to come back here for a month!"
+
+Then his attention was attracted to the savage growl of some animal in
+the thicket beyond the fire limit of the "burn." It seemed to the boy as
+if some man-eating creature had cornered a bit of animate supper, but
+couldn't reach it. The language used by the forest resident seemed to be
+in the tongue of the panther. While he listened a cry which was not that
+of a hungry beast came out of the gloom.
+
+That was a cry for help, surely. Frank put his revolver and his
+searchlight into convenient pockets and set out for the scene of the
+disturbance, without awakening any of the sleepers. It was slow work
+pushing through the bushes, and the boy wondered if a fire there, well
+guarded on a quiet day, wouldn't be a good thing.
+
+He kept his searchlight ahead and looked about for the source of the
+noises as he advanced in the darkness. In a short time he heard a voice
+he knew, but hardly expected to hear there.
+
+"Hurry up!" the voice said. "I'm goin' to tumble out of this tree in
+about a minute! I'm that hungry! I thought you might meet me with a pie
+under one arm."
+
+"Well, why don't you come down, then?" Frank asked.
+
+"If you'll turn your honorable attention to that tree to the east,"
+Jimmie said, "your excellency will observe a panther waiting for his
+supper. He's been tracking me all day, getting bolder every minute. Now,
+if I turn this searchlight away for an instant, he'll jump on me, and
+there you are. No more Jimmie McGraw than a rabbit!"
+
+"I didn't see your light at first," Frank said, "for it was hidden by
+the foliage of the trees. I suppose you want me to shoot the cat?"
+
+
+
+
+CHAPTER XVII.--THE TIME FOR THE ROUND-UP.
+
+
+"Sure," Jimmie answered. "Shoot the cat!"
+
+"Well, keep your light on him, and wait until I can get where I can see
+him. The cat frequently resents being wounded."
+
+"Cripes!" cried Jimmie. "Don't shoot unless you kill him, for he'll jump
+at me then for sure. He's angry now--hear him pound with his tail? I
+fired all my loads at him an' he dodged the bullets."
+
+"You couldn't shoot craps!" scorned Frank.
+
+The panther, a great brute made ferocious by the excitement of the fire,
+and probably scorched a little, could now be heard moving in the
+branches of a tree not far from that in which Jimmie was perched. In a
+moment Frank reached a point from which the beast's face could be seen.
+
+He thought to himself that it looked like a tiger head fastened against
+a gray cloud with unseen pins. Jimmie's searchlight brought the evil
+face, the cruel eyes, the back-sloping ears, the faintly-moving jaws,
+out into strong relief, as the circle of flame was only large enough to
+cover the face.
+
+The beast heard Frank moving in the bushes below and turned its head to
+look, at the same time crouching low, as if to spring.
+
+The first bullet struck him fair in the throat, the second entered the
+head just above the eyes, the third, coming so rapidly on the others
+that the three reports seemed to merge into one, entered the body over
+the heart. The great beast was dead when the body struck the ground.
+
+Jimmie was not long in getting down to Frank's side and grasping him by
+the shoulders in a hug which threatened to end in a scuffle.
+
+"Get away!" Frank said. "Suppose there's another cat here? If there is
+he'll get one of us through your foolishness."
+
+"There were two," Jimmie said, coolly, "but I killed one."
+
+"How did you get here?" was the next question, asked as the boys turned
+toward the camp.
+
+"How do you think I got here?" returned Jimmie.
+
+"Walked!" laughed Frank.
+
+"Yes, I walked."
+
+Jimmie stopped and rubbed his legs with careful hands.
+
+"I'm all wore out!" he said. "I can't walk any farther to-night."
+
+"All right," Frank said, with a grin. "I'll leave you both lights to
+keep the cats off with, and my gun, and come out after you in the
+morning after breakfast."
+
+"Oh, my eats!" Jimmie cried. "Lead me to something that will sustain
+life! I'm starving, I tell you."
+
+"You walked all the way?" asked Frank.
+
+"Sure! Forty miles at least."
+
+"Where are the others?"
+
+"Pat, Jack and the Chink Scout? Pat came up just before I started,
+riding on a burro, an' in the custody of a small party of rangers, who
+thought he had been setting fires. The rangers went into camp over
+there, all tired out, an' Jack an' Pat settled down with them. I run
+away."
+
+"They don't know where you are?" asked Frank.
+
+"Nix know!" replied the boy.
+
+"But how did you ever get through the burning forest?" asked Frank,
+hardly believing the boy's story of his long walk.
+
+"This 'burn' is only a mile wide," Jimmie said. "I walked on the south
+edge of it. Say, there are plenty of lives lost! Bears, an' cats, an'
+all that. I guess this will be an agreeable place to live in about a
+week--not!"
+
+The boy was indeed "all in," as he expressed it. He had walked since
+early morning through a tangled forest black with smoke, through an
+atmosphere burned and smoked out of its life-giving qualities. And all
+this exertion in order that he might be near his chum, Nestor.
+
+Fortune had favored the lad, and he had at last blundered on the camp
+where Ned had taken refuge, otherwise he might have died in the forest
+from hunger and exhaustion, or been devoured by some of the savage
+beasts which had followed him all day.
+
+"Where's Ned?" Jimmie asked, as they stood before the little row of
+tents.
+
+"Asleep," was the reply, "and you let him alone for to-night. He's been
+having a lively time. But how in the name of all that's wonderful did
+you ever find your way here?" the boy added.
+
+"I don't know," was the reply. "I knew that Ned would be wherever the
+fire was, and so started east. Not so very long ago I heard a couple of
+shots, and that directed me toward the camp. Who was hurt?"
+
+Frank explained, briefly, what had taken place, hunted up a liberal meal
+for the boy, and then saw him settled for the night.
+
+Ned's astonishment at seeing the boy in the morning may well be
+imagined.
+
+"Huh!" Jimmie said. "You thought you would fool me out of all the fun!"
+
+Ned laughed and asked about the others, finally informing Jimmie that he
+was leaving that morning for San Francisco by the aeroplane route.
+
+"Then I'm goin'!" declared the boy. "I'm not goin' to be chucked into
+the discard again."
+
+"You'll have to sit in Frank's lap," grinned Ned, "and the machine may
+tip over with such a load, at that."
+
+"I guess it didn't tip over when Frank and Jack an' yours truly run it,"
+Jimmie replied. "Anyway, I'm goin' with you."
+
+Before leaving for Missoula, where he was to surrender the aeroplane to
+Frank, Ned had another long talk with Mr. Green, whose wound was not so
+serious as it had been considered the night before. The forester told
+him what he knew of the men under the leadership of Greer, saying that
+he might have arrested Greer at any time during the month, and, what is
+more, convicted him of smuggling both Chinamen and opium over the
+border.
+
+"But what good would it have done?" Green went on. "The conspirators in
+Washington, or New York, or San Francisco would have chosen another
+leader, and the game would have gone on as before."
+
+"That is very true," Ned admitted, "and still, it seems to me that the
+time to round the fellows up has come!"
+
+"Do you give that as an order?" asked the other, a flash of excitement
+showing in his face.
+
+"Yes," was the reply.
+
+"But some of them have gone to Portland with the Chinks--some to Frisco,
+I think. What about that?"
+
+"If you can spare men," Ned said, "follow them."
+
+"You're on!" laughed Green. "I've been waiting for some such orders for
+a long time. You're on!"
+
+"And follow on to Frisco as soon as you can," Ned continued. "Address
+me, or look for me, if you are able to be about after you get there, at
+the Federal building."
+
+"I'll be there in a week," Green said, his eyes showing the joy of the
+coming fight with the outlaws, "and I'll have a bunch of prisoners with
+me."
+
+The forester hesitated a moment, as the importance of the proposed move
+came to him, then faced Ned with a hesitating look. It was plain to the
+boy that Green wanted to ask a question which he believed to be either
+personal or impertinent.
+
+"Is there something else?" Ned asked.
+
+Green still hesitated, his eyes on the ground.
+
+"Are you sure of your clues?" he asked, then.
+
+"I think so," was the reply.
+
+"Because, you see," Green went on, "the government doesn't want any trap
+sprung until the whole bilin' is within reaching distance. After the
+good work you have done here, I wouldn't like to have you order the
+round-up and then find that the men you wanted were still out on the
+range."
+
+"Thank you for your frankness," Ned replied.
+
+"I just want to be sure that you are sure," smiled Green. "It would mix
+things for me to make these arrests and have the big ones get away, now,
+wouldn't it?"
+
+"Indeed it would," Ned admitted, "but I think it is safe to go ahead as
+we planned a moment ago."
+
+"All right!" Green said, but there was still doubt in his eyes.
+
+"And I'll accept all the responsibility," Ned added.
+
+"I have a suggestion to make," Green said, then. "Why not go on to
+Frisco in the aeroplane and ask for instructions? You can make the trip
+in the airship in no time, but it is a long ride by rail."
+
+"I think," Ned replied, with a laugh, "that the game will be ripe just
+about the time I get to Frisco by rail. Besides, I don't want the
+outlaws to know that I'm going to the city. They would know it if they
+saw the aeroplane making for the coast. Well, if I leave Frank
+navigating it in this district they will think I am still here. Don't
+you see?"
+
+"Go it!" laughed Green. "I reckon you know what you're about."
+
+"Anyway," Ned said, "I've got to play the game in my own way if I play
+it at all."
+
+"I see," observed Green, and the two parted.
+
+The aeroplane had not been damaged at all by the fire, but Ned went over
+it carefully before attempting a start. Sawyer, trembling with fright,
+was brought out to show where he had meddled with the machinery.
+
+"I didn't harm it any," the prisoner said.
+
+"There are some burrs missing," Ned said.
+
+Sawyer brought half a dozen out of a pocket and passed them to Ned with
+a reluctant hand.
+
+"I neglected to tell you that I had them in my pocket," he said.
+
+"What did Green say to you this morning?" asked Ned, screwing the burrs
+on where they were needed.
+
+"He says he won't be hard on me, if I tell all I know about the men who
+are doing these tricks," was the reply.
+
+"You told me all you know?" asked Ned.
+
+"Yes, there is nothing else to tell. I'm so glad to think that Green is
+not going to die from the wound I gave him that I'll do everything in my
+power to bring the men who put me up to this to punishment."
+
+"Sure you can identify the man who hired you?"
+
+"Dead certain," was the reply.
+
+"Then I'll have one of the men bring you to Frisco," Ned said. "You will
+be wanted there."
+
+"All right; anything the government wants goes!"
+
+In half an hour the three boys, Ned, Frank and Jimmie, were on the
+aeroplane, sailing through the clear air of a splendid summer morning.
+Below they could see the long, narrow strip of land which had been swept
+by the fires. Off to the north was the British frontier, with Lake
+Kintla glimmering in the sunshine.
+
+"Aren't we going back to that lake cavern again?" asked Frank.
+
+"Not just now," Ned replied.
+
+"I didn't know that you got all you wanted in there," Frank went on. "I
+had an idea that you were trying to identify the man we found dead
+there."
+
+"I think I learned all there was to learn there," Ned replied.
+
+"He spent a lot of time in there before he went to Frisco," Jimmie said.
+"He made me go in there with him, and I didn't like it."
+
+"And so no one will ever know who the dead man was?" asked Frank.
+
+"I have been given a name," Ned said, "a name to call him by, but I
+don't exactly like to accept the information, considering the source
+from which it came."
+
+The aeroplane drifted to the west and north easily under the steady
+pulse of the motors, and the plateau where Jimmie had left the boys and
+the foresters was soon in sight.
+
+"I wonder if they're all alive?" said Jimmie.
+
+"What could happen to them?" demanded Frank.
+
+"Oh," Jimmie replied, with biting sarcasm, "there is nothing here to
+harm 'em! This is a pink tea, this is! This is a church fair, where you
+get ices made out of the cream they skim off the cistern!"
+
+"You're getting nutty!" Frank said, with a grin.
+
+"When I left 'em," Jimmie went on, "the boys an' the foresters were
+wondering if the outlaws would come back an' kill 'em one by one or just
+blow up the caves underneath the plateau an' send 'em up in the air
+without any good means of gettin' down."
+
+"Then we'll look them up," Ned said.
+
+The great divide lay down below, and the plateau was in plain sight,
+with the early sunshine streaming over it. When the aeroplane circled
+about it a shout came up to Ned's ears, then a shot, and the powder
+smoke drifted lazily upward in the clear air.
+
+"Somethin' doin'!" Jimmie cried. "Suppose we go down an' see."
+
+
+
+
+CHAPTER XVIII.--TWO INANIMATE WITNESSES.
+
+
+It was very still in the bachelor apartment, and, as on the occasion of
+his previous visit, Nestor saw, as he slipped through the doorway
+leading from the private hall, that the lights were burning low.
+
+On this night there was no opium-drugged victim lying on the couch.
+There was a movement in the room beyond, and Ned could hear the soft
+tread of slippered feet and occasionally the rattle of dishes. It was
+evident that midnight luncheon was being prepared, and that the master
+of the habitation would soon be on hand.
+
+Closing the door softly--the same having been opened with a skeleton
+key--Ned stepped across the room to the writing desk which he had
+examined on that other night. After searching the half-open drawer for
+an instant, he took out a number of papers and examined them. He also
+took a check-book out and put it into a pocket. The papers he returned
+to the desk. The check-book was an old one, there being few blank checks
+in the binding, but plenty of stubs.
+
+Then Ned looked at the lock of the desk. It had been out of repair at
+his previous visit, but was in excellent shape now. He removed the new
+key and inserted the one with the broken stem which had so excited the
+interest of Albert Lemon and Jap on occasion of his previous visit.
+
+The key with the broken stem did not fit. A new lock had been put on.
+Next Ned went to a mantel over a gas grate and lifted the cover from a
+little ivory box which stood there. At the very bottom of the box, under
+buttons, pins, needles, and odds and ends, he found a key. This one was
+whole, and it was an exact duplicate of the one with the broken stem.
+
+Ned had been in San Francisco three days, and Jimmie was not far away.
+On bringing the aeroplane to the plateau on the day of his return to
+Missoula he had found Ernest Whipple, Jack, Pat, Liu, and a small party
+of rangers anxiously awaiting him. Also "several tough ones waitin' for
+an introduction," as Jimmie put it. It seems that the fake foresters had
+returned to the cave after the fire in the canyon had burned itself out
+and had at once discovered that the prisoner had vanished, also that
+Liu, the Chinese boy, had disappeared with him.
+
+There had been a long search for the missing boys, as the outlaws knew
+very well that the escape meant the bringing of officers to the caves,
+but they had not been discovered until a short time before the arrival
+of the aeroplane.
+
+When Ned reached the plateau--in fact, before he reached it--he heard
+the whistling of bullets aimed at the big bird. The outlaws were trying
+to cripple the aeroplane and so give the riders a tumble. The boys
+landed in safety, however, and joined the others.
+
+Seeing the boys thus reinforced, the outlaws had withdrawn, and the
+rangers had conducted them to a pass which led over the divide. So it
+was that Ned had left them, making their way down toward the Valley of
+the Wild Animals, where a large number of rangers were encamped, and
+where Frank was to come for them with the aeroplane as soon as Ned
+landed at Missoula.
+
+There were numerous shots fired at the aeroplane as it mounted into the
+sky again, but no harm was done.
+
+"If they had been shootin' at that cat last night," Jimmie said, in
+derision, "they would 'a' been eaten alive."
+
+"They are nervous," Frank said, "and don't dare come out of their hiding
+places so as to get a good sight at us. They are afraid of the rangers,
+and afraid that we'll drop a bomb or something of that sort down on
+them."
+
+This explanation of the bad marksmanship, as well as the failure of the
+outlaws to rush the aeroplane, was accepted by the boys, who had
+anticipated a fight with the fellows. It was afterwards learned, too,
+that there were only half a dozen outlaws in the group, and that they
+had been sent back to guard the caves and not to fight rangers unless
+they were attacked.
+
+Ned had been very busy since his return to the city, having made many
+inquiries concerning Albert Lemon and his servant, the Japanese
+attendant who had given the boy such a chilly reception on the night of
+the first visit.
+
+Lemon, he had been informed, was a millionaire of eccentric habits.
+According to Ned's source of information, he would absent himself from
+his usual haunts for days at a time, and would then return to shut
+himself up in his rooms, at home to no one, and attended only by Jap.
+
+After a time the clatter of dishes grew louder in the adjoining room,
+giving notice, doubtless, that the luncheon being prepared was nearly
+ready to serve. Then the boy seated himself behind a screen which cut
+off a corner of the room and waited. He had occupied his retreat only a
+short time when a key turned in the door and the man he had talked with
+on his first visit entered.
+
+It was not the old, half-dazed, disreputable Lemon who stepped into the
+room, but a young man handsomely dressed and evidently very wide awake
+and in the best of spirits. After seeing that the window shades were
+closely drawn he turned on the lights and dropped into a chair at the
+writing desk.
+
+Ned saw him rummage the pigeon-holes for a moment, extract a folded
+paper, and fall to checking off the items. The boy had examined this
+sheet while at the desk, and so knew what it contained. After checking
+the items the man drew out a long pocket-book and placed its contents on
+the writing board.
+
+The boy gave a quick start when he saw what the book had contained, for
+a large package of yellow-back bank notes lay exposed to view. The man
+counted them carefully, compared the total with the figures he had
+marked on the sheet, and then sat back in his chair with a satisfied
+smile on his face.
+
+"Everything correct!" he said.
+
+Then he lighted a cigar and turned to the door opening into the inner
+room.
+
+"Jap!" he called softly. "Oh, Jap!"
+
+The door opened and the servant looked in.
+
+"Come here!" Lemon commanded. "What have you been doing?" he added, as
+the Jap stood before him.
+
+"Nothing," was the reply.
+
+"You are not telling the truth," Lemon said. "You have been seen about
+the city, in tea houses, talking with strangers."
+
+"I have not been out of the rooms," the other insisted, stubbornly.
+
+"Let it pass," Lemon said, in a moment. "There may be some mistake. Any
+one been here?"
+
+"No one."
+
+The servant appeared to have a perfect knowledge of English. He looked
+into his master's face with a bland smile, but now and then his eyes
+sought the screen behind which Ned was hidden.
+
+"Well, some of the boys will be up here to-night," Lemon said. "See that
+there is plenty to eat. Go, now."
+
+The servant turned to the door opening into the private hall, stood with
+his hand on the knob for an instant, and then, apparently changing his
+mind, went out through the doorway by which he had entered. If Lemon had
+been listening intently he would have heard a quick movement in the back
+room as Jap closed the door.
+
+In a moment there was another movement in the private hall, and then Ned
+heard the corridor door open. He pushed the screen aside and stepped out
+before the astonished occupant of the rooms.
+
+"What does this mean?" Lemon demanded, a quiver of excitement--or it
+might have been consternation--in his voice.
+
+While he spoke he moved toward a table where a revolver lay in full
+view.
+
+"Never mind that," Ned said, coolly. "We can arbitrate our differences
+without its assistance. Besides, it is not loaded."
+
+"What are you doing here?" Lemon almost shouted, his face growing white,
+either with rage or fear. "Leave the room immediately."
+
+Ned dropped into a chair and motioned toward another.
+
+"Sit down!" he ordered.
+
+"Your impudence is amazing," Lemon said, but he took the chair.
+
+In a moment, however, he turned to the door.
+
+"Jap!" he called.
+
+Again the door opened and the servant looked in.
+
+"Are you armed?" Lemon asked.
+
+The servant nodded, fixing a pair of inscrutable eyes on Ned's face as
+he did so.
+
+"Very well," was the reply. "Stand there by the door. How did this man
+gain entrance here?"
+
+The only reply was a shrug of the shoulders.
+
+"Let it pass for the present," Lemon said, with a smile of triumph.
+"Stand there and shoot when I give the word."
+
+The servant nodded again. Ned remained seated, his eyes fixed coolly on
+the face of the master.
+
+"Now, what do you want?" demanded Lemon. "You don't look exactly like a
+common sneak thief."
+
+"You doubtless remember," Ned began, in a level voice, "that I did
+myself the honor of calling at these rooms not long ago in quest of
+information of one--of one Felix Emory?"
+
+Lemon started at the name, but gained confidence as he glanced toward
+the servant at the door.
+
+"Yes, I remember," he said. "What about it?"
+
+There was a sharp ring at the corridor door before Ned spoke again. The
+Jap looked inquiringly at his master.
+
+"Company may prove of value just now," Lemon said. "Will you see who is
+there?"
+
+It was clear to Ned that Lemon expected some of the associates he had
+mentioned as "the boys" when giving instructions about the luncheon, and
+there was a smile of welcome on his face when a bustle in the hall told
+of an arrival.
+
+There was only one man, however, and Lemon at first seemed disappointed,
+but in a moment he had his face under perfect control again.
+
+"Father!" he cried, springing to his feet. "It is good to see you here!"
+
+The newcomer, a man of perhaps sixty, well dressed and with the air of a
+man to whom marked attention was due, stood looking into Lemon's face
+for an instant and then grasped his hand.
+
+"You have changed little, my son," he said.
+
+Lemon smiled and indicated Ned with a slight motion of the hand.
+
+"Permit me to present to you my father, Mr. Leon Lemon," he said, "and
+this, father, is a boy burglar who broke into my rooms in quest of
+plunder a short time ago," he added. "We were having quite a cheerful
+talk when you came. I don't know his name, unfortunately."
+
+The old gentleman gave a start and attempted to rise from his chair.
+
+"Don't distress yourself," Lemon said. "He is quite harmless. Besides,
+Jap has him covered with the cannon he delights to carry."
+
+"This is a strange situation," the other said, wiping the sweat of
+excitement from his face.
+
+"One of the incidents which add to the joy of life," Lemon said. "You
+remember Felix Emory?" he added. "Well, his pretense for this call is
+that he came to ask about him. Go ahead, Mr. Burglar."
+
+"Perhaps you will also remember," Ned went on, "that on my former visit
+here I exhibited a key with a broken stem--the key to that writing
+desk?"
+
+Lemon's face hardened and he glanced furtively at the servant, but said
+not a word.
+
+"This key," Ned said, producing the one mentioned, "was found in the
+pocket of the man who was found dead in the Rocky Mountains. You think
+you left it in the suit of clothes you gave Emory?"
+
+"Possibly," was the strained reply. "But we have had enough of this,"
+Lemon added. "Call the police, Jap."
+
+"Just a moment," Ned went on, when the Jap moved toward the door. "When
+you could not find the key, Mr. Lemon, why didn't you use the duplicate.
+The duplicate you kept in the box on the shelf? Why did you think it
+necessary to break the lock?"
+
+"The servant did that," was the angry reply.
+
+"I see," Ned replied, coolly, "perhaps that was done while you were up
+in the mountains with Emory--before he was killed?"
+
+"Possibly," Lemon gritted out.
+
+"Now, since talking with you," Ned continued, "I have been up in the
+mountains. There I found a man using a typewriter. By the way, have you
+a machine here?"
+
+"Certainly not," was the angry reply.
+
+"But you formerly used one here?"
+
+"Never!" was the reply.
+
+"That is strange," Ned said, "for when I came in here not long ago I
+took the liberty of looking through some papers in your desk, for which
+I ask your pardon. Well, I discovered that the machine you used here
+carried a defective letter 'c.' It looked in the writing like an 'o.'
+The machine the man was using under the divide had the same defect. If
+you will observe the sheet you were examining a few moments ago, you
+will note the imperfect letter."
+
+Lemon's teeth clinked together sharply, but he did not speak.
+
+"When I came here last," Ned continued, "you lay in an opium stupor on
+that couch. You had recently returned from a trip to Lake Kintla, where
+Emory was found dead. While in that section you visited a cavern on the
+eastern slope of the divide. There is where you used the typewriter
+taken from these rooms."
+
+"My son never learned the keyboard," said the old gentleman, an angry
+snap in his eyes. "He has never found it necessary to earn money."
+
+Lemon turned to the old man and bowed, gratefully.
+
+"When you lay on the couch that night," Ned continued, "there was the
+smear of the typewriter on the middle finger of your left hand, close to
+the nail. I use a double keyboard machine myself, and sometimes smut my
+finger on the ribbon when I turn the platen. Some papers I chanced upon
+in the mountains bear the mark of a smudged hand. You are careless in
+using the machine. You even left a blue record ribbon in the cave
+headquarters where the dead man was found. That was my first valuable
+clue!"
+
+"What papers did you steal while in the mountains?" demanded Lemon,
+springing to his feet, his face deadly white, his fists swinging
+aimlessly in the air.
+
+"Lists," Ned replied. "Lists of Chinamen brought from over the border,
+and lists of opium cases smuggled in. I have the papers in my possession
+now. They match with the statement you examined just before I made my
+appearance in the room--just before you counted the money you received
+from this illegal traffic."
+
+The old man leaped at Ned, but the boy moved away and stood by the door.
+The Jap stepped closer. There came a sound of whispering, a noise of
+footsteps, from the hall outside. Then the door was opened and Greer,
+Slocum, Chang Chee and two others entered, glancing keenly at Ned as
+they passed him, still standing by the door.
+
+"Do you mean to accuse my son of crime?" shouted the old man, not
+noticing the new-comers in his rage and excitement. "You scoundrel!"
+
+"How do you know," Ned asked, with a smile at the others, "that this man
+is Albert Lemon, your son?"
+
+
+
+
+CHAPTER XIX.--THE MAN BEHIND THE SCENES.
+
+
+"Not my son!" shouted the old man. "This has gone quite far enough! Jap,
+call the police, and order this mad youngster taken away."
+
+The younger man broke into a harsh laugh and turned to those who had
+just entered. Slocum and Chang Chee were whispering together, and a
+dangerous looking knife showed in the hand of the false ranger.
+
+"You hear what father says, boys," Lemon said. "Remember that."
+
+"What is this kid doing here, anyway?" demanded Slocum.
+
+"He came here, evidently, for the purpose of blackmailing me," Lemon
+said. "He has papers stolen from the mountains--lists, he says they
+are--and they should be taken from him by force."
+
+Slocum and Chang Chee started toward the boy, but he waved them back
+with his hand.
+
+"I will lay the papers on the table," he said. "You are quite welcome to
+them for the present."
+
+"I'll take him down to the police station," said Chang. "He ought not to
+be at large. Come, youngster."
+
+"You seem to be able to talk pretty good English now," laughed Ned.
+"Much better than the slang you gave out in the mountains."
+
+"Come!" shouted the Chinaman. "You are here alone, so there is no need
+of a fight. Come along!"
+
+"We'll see about my being here alone presently," Ned said. "Anyhow, I'd
+better be here alone than with any one of you in the dark streets. I
+should be murdered before a block was passed. That is what you came to
+Frisco for, to murder me--just as the man in the lake cavern was
+murdered."
+
+Those in the room looked at each other and remained silent. There was a
+tense moment, when every person there seemed gathering for a spring,
+when the lust of blood seemed in every glaring eye, but it passed.
+
+"Where are the Chinamen you brought away from the British border?" asked
+Ned of Chang Chee. "Are they in this city? Oh," he continued, as Chang
+glared at him, "we knew that you were about to bring in a batch. You
+usually light forest fires in order to attract the attention of the
+rangers when you get ready to unload a band of Chinese on Uncle Sam.
+That is Doyers street cunning, Chang!"
+
+"You see," he went on, "we have had the good luck to discover why the
+forests in Northern Idaho and Montana have been set on fire so
+frequently. I don't care to say what I think of the wisdom of your
+course in so attempting to hide your movements, except that it attracted
+attention instead of diverting it. You firebugs might have been arrested
+long ago," he continued, turning to Slocum, "but it was thought best to
+wait until the head center of the whole conspiracy was in the hands of
+the law. Now that this has been accomplished, I may speak."
+
+The people standing around the boy looked into each other's faces, and
+there was a movement as if to draw weapons.
+
+"Permit me to congratulate you on the discovery of the leader of the
+outlaws," the old man said with a snarl. "Perhaps you will be kind
+enough to give us his name?"
+
+"There are no objections that I know of," was the reply. "His name is
+Felix Emory. You may have heard of him."
+
+"An old acquaintance of my son Albert," the old man said.
+
+"That is the name of the man who was so mysteriously murdered in the
+Kintla lake cave," Slocum observed. "Why do you place the crime on the
+dead?"
+
+"Felix Emory," Ned said, "is not dead. He is alive at this moment--alive
+and in this room!"
+
+The young man broke into a jarring laugh and turned to the old man.
+
+"You remember the strange resemblance between Felix and myself," he
+said. "Well, it seems to have deceived this clever young man. By the
+way, Slocum, why don't you take the lad to the police station? We have
+no more time for him here."
+
+Slocum and another sprang forward, but Ned opened the door with a quick
+motion and stood beyond their reach.
+
+"The man found dead in the cave," the boy said, facing the old man, "had
+met with an accident in his youth. The first joint of the little finger
+of the right hand was missing. Also, there was a scar over his left
+eye--a trifling scar, made with a knife in the hands of a playmate. Do
+you recall these marks of identification, Mr. Lemon?" he added.
+
+The old man threw his hands to his face and stood silent for a moment
+while the others looked on in perplexed silence. When he uncovered his
+face again he stepped forward to the man he had called his son on
+entering the room.
+
+"Let me see your hands, Albert," he said, kindly. "Bend down so I can
+see the scar on your forehead!"
+
+"Step aside, you old fool!" the young man cried, pushing the old man
+back rudely. "We have had enough of this, boys," he continued, turning
+to the others. "The game is up unless we get rid of this dotard and this
+boy. Why don't you get busy?"
+
+The old man dropped into a chair and lifted his face to Ned's.
+
+"You found my son murdered?" he asked. "Then this man Felix Emory stands
+in his shoes! Even I was deceived by him! Why, he has been calling upon
+me for large sums of money during the past month. He has taken
+possession of my boy's rooms. Was it this man Emory who killed him?"
+
+"We believe so," was the reply. "The proof is within reaching distance."
+
+"Out with them both!" shouted Emory.
+
+"Your son Albert took this man in and tried to do something for him,"
+Ned went on, "and was robbed and murdered for his pains. This man Emory
+was the leader of this choice band of smugglers and firebugs when he
+came to your son. The band was on the point of scattering because the
+officers were close on their track. They needed a man well up in the
+world--a man against whom the breath of suspicion had never been
+blown--to represent them in the opium market and the smuggled Chinamen
+market. They sent this man Emory to your son with a proposition, and he
+turned him down. Then they parted. But Albert knew too much and so he
+was lured to the woods and killed, and Emory stood before the world as
+your son. It was a devilish plot, great wealth being the object. If you
+will look at the stubs in this check-book you will see the difference in
+the hand-writing."
+
+"I rather admire your nerve, boy," Slocum said to Ned. "You've got the
+right kind of courage to stand up here and tell all this to us. You know
+very well that we can never let you go out of this place alive? That
+even this old man must suffer for your bit of foolish daring?"
+
+"I'd like to have the training of that kid for a few years," Chang said.
+"I could beat the world with him!"
+
+"Well, you all know what we've got to do," Emory said, angrily. "We've
+got to get rid of the boy and this old man. If we do not, there is an
+end of a rather profitable business. Besides, with Albert Lemon dead, I
+become his heir, with no possible chance of being identified as Felix
+Emory."
+
+"You devil!" shouted the old man. "You murderer!"
+
+Enraged by the exclamation, Emory made a rush for the old man, but was
+stopped by a voice from the doorway opening into the rear room.
+
+"That'll be all for you!" the voice said.
+
+It was Jimmie who stood in the doorway, smiling, and making about the
+worst bow a Boy Scout ever made.
+
+"Don't wiggle about so, gentlemen," he added, "for the men behind this
+partition have you all covered with repeating rifles, and some of them
+are nervous. Stand still while a friend of mine presents you with
+wristlets."
+
+Jap turned and faced the frightened group and then pointed to the wall,
+near the ceiling, where a line of two-inch holes were seen, at each hole
+a shining eye.
+
+"You see," he said, "I cut those holes there to-night, so the boys
+wouldn't have to lie hidden under the furniture. There's a gun behind
+every one of them. And now, with your permission--"
+
+Jimmie passed out a bunch of clattering, ringing handcuffs, and Jap
+slipped them on the wrists of the prisoners. As he did so Frank came
+dashing into the room, swinging his cap aloft. Ernest, Jack, Pat and Liu
+were there, too, overjoyed at the great victory.
+
+"Wow!" he cried. "Here's a wire saying that the bunch was captured at
+Portland to-night, and another from Missoula says the men left in the
+caverns were caught yesterday. I have the honor to report, Mr. Sherlock
+Holmes Nestor," he added, with a low bow, "that the round-up is
+complete."
+
+"Our day will come directly," Emory shouted. "You haven't a word of
+proof against any of us. Your story sounds all right here, but wait
+until you get into court. Our lawyers will pick your yarn apart like a
+rag doll. And you, Jap," he went on, turning to the servant, "when did
+you turn against me?"
+
+"There have been two instances of false personation in this case," Ned
+said. "You, Emory, personated Albert Lemon, whom you murdered, and you,
+Jap, personated the servant Emory brought here after he had seen you
+carried out of the rooms for dead."
+
+"Then that isn't my servant at all?" asked Emory.
+
+"I was in the employ of Albert Lemon," answered the Jap, "when you took
+him away and killed him. When you came back from the mountains you
+caused me to be drugged and killed, as you supposed. But your servant
+hesitated in the work. He finally turned against you, and permitted me
+to come here in his stead. It was he who disclosed the hiding place of
+the duplicate key. He told me, and I told Mr. Nestor."
+
+"It is all a blackmailing conspiracy!" cried Emory.
+
+"When Mr. Nestor came back to the city, three days ago," the servant
+went on, "I was told by the man I was personating in these rooms that
+the whole plot was known. He said that Mr. Nestor knew that you were not
+Albert Lemon, also that I, Albert Lemon's servant, still lived. I didn't
+have much to tell him when he came to me, but I told him all I knew."
+
+"And you let him search my rooms?" cried Emory.
+
+"Of course," was the cool reply. "He has everything required to send you
+to the gallows for the murder of Albert Lemon, and everything necessary
+in the case against the smugglers and firebugs, too. He found Emory's
+servant," he added, facing the father, "in a Japanese tea house, and
+brought him here to me after the closing scene was set for to-night. You
+may talk with him if you want to. He can tell you how the murder of your
+son was planned, also how the plot to kill Mr. Nestor in the mountains
+was laid--here in these rooms."
+
+Again the old man sank into a chair and buried his face in his hands. It
+was a severe blow to him. He had arrived in San Francisco that day,
+anticipating a pleasant month with his son. And now to find him dead!
+
+"It would be interesting," said Slocum, speaking for the first time
+since the arrests, "to know just how this remarkable boy discovered the
+connection between this flat and the mountain caves."
+
+"The murder brought the clue," Ned replied. "From the first the clue led
+here. And then the key without a stem, the smudge on Emory's finger, the
+typewritten sheets, the machine in the mountains--oh, it was all easy
+enough after the discovery that this man Emory did not know where Albert
+Lemon kept his duplicate key to that desk!
+
+"The case is ended," Ned continued, "and all the parties wanted by the
+law are under arrest, so, if you don't mind, gentlemen, I'll go to bed!"
+
+Jack, Pat, Ernest and Liu now advanced into the room and looked
+smilingly at their leader.
+
+"You can't lose us," Jack said. "If you don't mind, we'll take you back
+to the Rocky Mountains for a little fun with the aeroplane. I guess
+there won't be any bold bad smugglers up there to distract our attention
+for a few weeks."
+
+"And then," Jimmie cut in, "I hope you'll all go back to little old New
+York. I'm hungry and thirsty, and sleepy for a walk down the good old
+Bowery and the wise old White Way!"
+
+The case against Felix Emory was so complete that he pleaded guilty on
+being arraigned in court and was sentenced to the gallows. Chang
+received a long sentence for his connection with the murder, and the
+smugglers and firebugs were sent to prison for ten years each.
+
+The clean-up was so complete that Ned was requested to visit Washington
+and confer with the Secret Service chief regarding other cases.
+
+"But, after all," he said, on leaving Jimmie and the other boys,
+including Ernest and Liu, in New York, "I don't think I want any more
+fighting forest fires assignments in the Secret Service. We'll go back
+some day and look over the ground, but I don't think I'll ever be able
+to get some of those rides in the air out of my mind."

+WOODCRAFT
+for Boy Scouts and Others
+
+By OWEN JONES and MARCUS WOODMAN
+
+With a Message to Boy Scouts by SIR BADEN-POWELL, Founder of the Boy
+Scouts' Movement.
+
+One of the essential requirements of the Boy Scout training is a
+Knowledge of Woodcraft. This necessitates a book embracing all the
+subjects and treating on all the topics that a thorough knowledge of
+Woodcraft implies.
+
+This book thoroughly exhausts the subject. It imparts a comprehensive
+knowledge of woods from fungus growth to the most stately monarch of the
+forest; it treats of the habits and lairs of all the feathered and furry
+inhabitants of the woods. Shows how to trail wild animals; how to
+identify birds and beasts by their tracks, calls, etc. Tells how to
+forecast the weather, and in fact treats on every phase of nature with
+which a Boy Scout or any woodman or lover of nature should be familiar.
+The authorship guarantees its authenticity and reliability.
+Indispensable to "Boy Scouts" and others. Printed from large clear type
+on superior paper.
+
+Embellished With Over 100 Thumb Nail Illustrations Taken From Life.
+
+Bound in Cloth. Stamped with unique and appropriate designs in ink.
+
+Price, 75c Postpaid

+
+
+Section 1. General Terms of Use and Redistributing Project Gutenberg-tm
+electronic works
+
+1.A. By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the
+phrase "Project Gutenberg" appears, or with which the phrase "Project
+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3. If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder. Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.

+1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form. However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7. Do not charge a fee for access to, viewing, displaying,
+performing, copying or distributing any Project Gutenberg-tm works
+unless you comply with paragraph 1.E.8 or 1.E.9.

+- You pay a royalty fee of 20% of the gross profits you derive from
+ the use of Project Gutenberg-tm works calculated using the method
+ you already use to calculate your applicable taxes. The fee is
+ owed to the owner of the Project Gutenberg-tm trademark, but he
+ has agreed to donate royalties under this paragraph to the
+ Project Gutenberg Literary Archive Foundation. Royalty payments
+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and

+ address specified in Section 4, "Information about donations to
+ the Project Gutenberg Literary Archive Foundation."
+

+ you in writing (or by e-mail) within 30 days of receipt that s/he
+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+ money paid for a work or a replacement copy, if a defect in the
+ electronic work is discovered and reported to you within 90 days
+ of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+ distribution of Project Gutenberg-tm works.
+
+1.E.9. If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from. If you
+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5. Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.

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