+CHAPTER I.
+
+CAPTURING AN AIR-SHIP.
+
+
+"Py shiminy grickets! Vat do you t'ink oof dot! See dere vonce, Matt. A
+palloon, or I vas a lopsder! Und vat a funny palloon it iss."
+
+Motor Matt and his Dutch chum, Carl Pretzel, were sitting by a quiet
+country roadside, in the shade of some trees. Drawn up near them was a
+light touring-car.
+
+The boys were several miles out of the city of Chicago, from which
+place they had started about the middle of the forenoon, and they had
+halted in that shady spot between Hammond and Hegewisch to eat the
+lunch they had brought with them. Carl had just finished the last piece
+of fried chicken when, happening to look skyward, he saw something
+that brought him to his feet with a jump. As he called to his chum, he
+pointed with the "drum-stick," at which he had been nibbling.
+
+Matt's surprise was nearly as great as Carl's, and he likewise sprang
+up and gazed at the air-ship, which was coming toward them from the
+north and east, making smart headway against the wind.
+
+"Great spark-plugs!" exclaimed Matt. "That's the first air-ship I ever
+saw."
+
+"Vat's der tifference bedween a palloon und a air-ship?" asked Carl.
+
+"Well, you can navigate an air-ship with the wind or against it, while
+a balloon is at the mercy of every current that blows. A round gas-bag
+and a basket is a balloon, Carl, but when you add a gasolene-motor and
+a propeller you have an air-ship."
+
+"Dot's blain enough. Der air-ship iss sky-hootin' dis vay to peat four
+oof a kindt. Say, it looks like a pig cigar. Vat a funny pitzness! Und
+you nefer seen vone pefore, Matt?"
+
+"I never saw one that would travel successfully. This one, though,
+seems to be going in good shape."
+
+"You haf seen palloons meppy?"
+
+"More than I can count," said he. "I've been up in balloons a dozen
+times. When I was in the Berkshire Hills they used to have races, and
+start from Pittsfield. That's where I began making ascensions."
+
+Carl dropped his wondering eyes to Matt for a moment.
+
+"You vas der plamedest feller!" he exclaimed. "You haf tone more t'ings
+as any feller I ever see, und you nefer say nodding ondil it shlips
+oudt, like vat it toes now."
+
+Motor Matt made no answer to this. Just then his attention was
+completely absorbed by the air-craft.
+
+As near as he could judge, the cigar-shaped gas-bag was more than a
+hundred feet long. Beneath the bag was suspended a light framework.
+Midway of the framework was an open space, containing a chair in which
+sat the man who was handling the motor. Out behind the driver the
+framework tapered to a point, and at the end of this rearmost point
+was the whirling propeller. The glittering blades caught the sun in a
+continuous sparkling reflection, which made the air-ship appear to be
+trailed by a glow of fire.
+
+Forward of the cockpit, or open space, was the motor. A rail ran around
+the cockpit.
+
+There were two men in the car--the one in the driver's seat and
+another in front of him, leaning over the rail. This second man seemed
+to be looking at the two boys, and to be waving his hand and giving
+directions to the driver.
+
+Along the side of the gas-bag Matt was able to read the name "Hawk,"
+printed in large letters.
+
+The Hawk was about a hundred feet above the surface of the earth.
+A long rope depended from the car, and twenty or thirty feet of it
+dragged along the ground as the car moved.
+
+"Vat's der rope for, Matt?" inquired Carl.
+
+"If that was an ordinary balloon," replied Matt, "we'd call the rope
+a guide-rope. Usually the guide-rope helps to save gas and ballast.
+When you want a balloon to go up, you know, you throw out sand; when
+you want it to come down, you let out gas. That trailing rope acts as
+ballast. When the gas expands, and the ship wants to rise, part of the
+rope that trails is lifted from the ground and throws more weight on
+the car; and when the gas contracts, and the car shows a tendency to
+descend, more of the rope falls on the ground and takes just that much
+weight off the car."
+
+"Dot's as clear as mud!"
+
+"I can't understand why they've got a drag on the air-ship," muttered
+Matt. "I supposed the propeller and the steering-blades were enough to
+send such a craft wherever it was wanted to go."
+
+As the Hawk came nearer, Matt's trained eyes and ears convinced him
+that the driver of the air-ship was a poor motorist. Evidently he did
+not understand the engine he was handling. The air-ship zigzagged
+erratically on its course, and the long bag ducked upward and downward
+in a most hair-raising manner. On top of that, Matt could hear one of
+the cylinders misfiring.
+
+The Hawk's drag-rope was trailing along the roadway. First it was on
+one side of the road, and then on the other, following the irregular
+swaying and plunging of the car.
+
+"Come on, Carl!" called Matt, turning and running for the automobile.
+"If that rope strikes our car it may damage it. We've got to fend it
+off."
+
+"Dose air-ship fellers vas mighdy careless!" answered Carl, hurrying
+after his chum. "Dot rope mighdt knock town fences, und preak vinders,
+und do plendy more tamages."
+
+"There isn't power enough at the other end of it to do much damage,"
+Matt answered, posting himself at the rear of the automobile and
+watching the advancing rope with sharp eyes.
+
+By that time the Hawk was almost over the boys' heads. The rope, of
+course, was dragging far out behind, and the trailing part of it bid
+fair to pass the car well on the right.
+
+"Hello, there!" shouted the man at the rail of the Hawk, leaning far
+over and making a trumpet out of his hands.
+
+He seemed to be excited, for some cause or other.
+
+"Hello yourseluf, vonce!" called back the Dutch boy. "Keep a leedle off
+mit your rope--ve don'd vand it to make some drouples for us."
+
+"The air-ship's out of control," the man shouted. "We can't stop the
+motor and the ship's running away! Grab the rope, hitch it to your
+automobile and tow us back to South Chicago. We'll give you a hundred
+dollars for your trouble. Be quick!"
+
+"I like his nerf, I don't t'ink!" growled Carl. "He vants to run off
+mit us und der pubble, und----"
+
+"We can tow the air-ship, all right," cried Matt, "providing we can get
+the rope fast to the automobile. We'll have to take a half hitch with
+the trailing end of the rope around a tree, and bring the air-ship to a
+stop."
+
+Matt started for the rope. As he bent down to lay hold of it, the car
+gave a lurch sideways and the rope was whisked out of his hands and was
+thrown directly against Carl's feet.
+
+Carl grabbed it. At the same moment the air-ship took an upward leap,
+on account of the weight which Carl had taken off the car. This leap
+flung Carl into the air. He turned a frog-like somersault, hands and
+feet sprawled out, and came down with a thump, flat on his back.
+
+"Whoosh!" he yelled, a good deal more startled than hurt, sitting up on
+the grass and shaking his fist at the bobbing craft overhead, "you dit
+dot on burpose! Vat's der madder mit you, anyvay? Vat for----"
+
+Carl forgot his fancied grievance watching Motor Matt. The latter,
+making another leap at the rope as it settled back again after
+overturning Carl, succeeded in laying hold of it.
+
+He had the rope by the end, so that when he picked it up none of the
+weight was taken from the ship, and Carl's disastrous exploit was not
+repeated.
+
+"Wrap it around a tree!" yelled the man at the air-ship's rail; "take a
+half-hitch around a tree!"
+
+The man might just as well have saved his breath. That had been Motor
+Matt's plan, all along, and even as the aeronaut was shouting his
+instructions Matt was jumping for the nearest tree.
+
+The young motorist had little time to make the rope fast. The whirling
+propeller was driving the Hawk onward against the wind at a fair rate
+of speed. Had there been no opposing wind, Matt would not have had time
+enough for the work ahead of him.
+
+"Come on, Carl!" he shouted.
+
+The Dutch boy stopped watching and made haste to lend a hand.
+
+Matt was already at the trunk of the tree, but the rope had traveled
+onward so rapidly that he had less than a yard of it in his hands to
+work with.
+
+Throwing himself on the opposite side of the tree, Matt laid back on
+the end of the rope. At that moment Carl reached his side, dropped near
+him and likewise took a grip on the free end of the drag.
+
+"It's der fairst time," panted Carl, "dot I efer heluped make some
+captures mit an air-ship. Shinks! Look at dot, vonce!"
+
+The driving propeller had forced the Hawk to the end of its leash. The
+boys, with only a half wrap of the rope around the trunk, felt the
+quick pull, but easily controlled it. The pull was steady, but, inch
+by inch, they worked more and more of the rope around the trunk until
+there was enough to make a knot.
+
+"Dot's der dicket!" exulted Carl, scrambling erect. "Ve've got her tied
+like a pird mit vone foot. Now how ve going to ged her hitched ondo der
+car?"
+
+"We'll have to find out what's the matter with the motor, up there,"
+answered Matt, "and see if the power can't be shut off."
+
+As he spoke, he got to his feet and walked down the road to a point
+directly under the air-ship.
+
+
+
+
+CHAPTER II.
+
+A QUEER "FIND."
+
+
+Both passengers in the air-ship were now leaning over the rail of the
+suspended car.
+
+"Hitch us on to your automobile," shouted the one who had been doing
+the driving, "and tow us back to South Chicago."
+
+The offhand way in which the man spoke proved that he was lacking on
+the practicable side of his nature.
+
+"That's a whole lot easier said than done," Matt called back. "It was
+only by a happenchance that we got your drag-rope tied to the tree. If
+you've got an anchor-rope up there, throw it down and we'll make it
+fast to the car before we cast off the other."
+
+"That's the only long rope we've got," answered the man.
+
+"Well," went on Matt, "you ought to be able to see what sort of a job
+we're up against. Your motor is pulling hard on the rope, and the
+moment we take the rope from the tree it will be jerked out of our
+hands. Don't you know how to run a gas-engine?"
+
+"I know how to start a gas-engine," was the amazing response, "but I
+don't know how to stop it."
+
+"Py shiminy grickets!" whooped Carl, "you vas a nice pair to shtart off
+mit a gasolene-air-ship. You vas in luck nod to make some landings on
+Chupiter, Mars or to hit a comic."
+
+Matt likewise thought it was an odd situation, but believed it would
+be well to get the two helpless aeronauts down on terra firma before
+asking for an explanation of their predicament.
+
+"Do either of you know what the gasolene-tank is?" he asked.
+
+The heads disappeared within the car for a moment, then one reappeared
+over the railing.
+
+"Yes, we've found that, all right," said the man.
+
+"And the carburettor--do you know where to look for that?"
+
+"Is that the thing that makes the spark?"
+
+Carl let off a howl of derision.
+
+"Ach, du lieber, vat a ignorance! Der carpuretter makes der gas, dot
+makes der exblosions in der cylinter, dot moofs der biston dot makes
+der bropellor go 'roundt. I know dot meinseluf, efen dough I vasn't so
+pright like Modor Matt."
+
+"There's a pipe leading from the gasolene-tank to the carburettor,"
+continued Matt, "and there's a valve which should be worked by a lever.
+Close that valve and you'll shut off the supply of gasolene. When you
+do that, the motor will stop, and we can work down here to better
+advantage."
+
+The head disappeared again and the car rocked and swayed as the two men
+scrambled around in it. Their ignorance, however, increased rather than
+lessened the difficulty. The misfiring of the one cylinder ceased and
+the motor took up its humming rhythm at an even faster speed. The fresh
+impetus of the propeller put a harder pull on the rope, and the strain
+bore sudden and unexpected results.
+
+With a yell of dismay the driver of the machine leaned over the rail of
+the car. He had thrown off his hat and his coat was unbuttoned.
+
+"We're making it worse!" he cried. "I wish to thunder you could come up
+here and----"
+
+Just then the drag-rope, which could not have been properly fastened to
+the car, let go and dropped earthward in sinuous coils.
+
+The man doubled farther over the rail in a futile and foolish effort to
+lay hold of it. Something fell from the pocket of his coat, fluttered
+through the air and landed in the top of a tree.
+
+Matt noted the flight of the fallen object only incidentally, for the
+major part of his attention was taken up with the actions of the car.
+
+The steering rudder had become elevated, and the air-ship started at
+a tremendous clip toward the clouds. The two aeronauts could be seen
+rushing around the car like mad. While the two boys watched, the rudder
+was brought down to a level; but something else had gone wrong, for the
+machine could not be maneuvered.
+
+Swiftly the air-ship diminished to a mere speck in the southern sky,
+and then vanished altogether.
+
+Carl turned a blank look at Matt and gave a long whistle.
+
+"Dot proofs, Matt," said he, "dot id don'd vas goot pitzness to monkey
+mit t'ings you don'd know nodding aboudt. Oof dose fellers run into a
+shooding shdar dere vill be some fine smash oops."
+
+"Why they ever ventured up in the air-ship, knowing so little about how
+to manage it, is a mystery."
+
+Matt gave his head an ominous shake.
+
+"Vat vill pecome oof dem?" queried Carl.
+
+"If they can get the steering rudder to working, they can drive the
+air-ship to the ground. Anyhow, the supply of gasolene will have to
+give out, in time, and then they may be able to come down."
+
+"Dere iss somet'ing crooked aboudt dose fellers. Oddervise, dey
+vouldn't be vere dey are."
+
+"Did you see something drop from the driver's pocket, Carl?"
+
+"Nix. Iss dot vat habbened?"
+
+"Yes. It landed in the top of that tree, over there."
+
+"Meppy ve ged holt oof der t'ing und find oudt somet'ing aboudt who
+dose fellers vas, und for vy dey vent off for a fly mitoudt knowing how
+to manach der flyer?"
+
+Matt proceeded to the foot of the tree in whose branches the fallen
+object had alighted. Lifting his gaze upward, he peered sharply into
+the foliage.
+
+"I see it," he announced, pointing.
+
+"Und me, too," said Carl. "It vas vite, und round, like a punch oof
+bapers rolled oop. How ve ged him down, hey? Meppy ve t'row some
+shticks ad him?"
+
+Suiting his action to the word, Carl picked up clubs and stones and
+hurled them upward in an endeavor to dislodge the object. Finding that
+these efforts were unsuccessful, Matt threw off his coat and hat and
+climbed the tree.
+
+The roll of papers was lodged far out in the fork of a branch. Standing
+on the branch, he jumped up and down on it and jarred the roll loose.
+Carl caught it deftly as it fell.
+
+"Hoop-a-la!" he yelled; "here she vas, Matt. Come down a leedle vile ve
+look him ofer."
+
+In a few moments Matt was again on the ground. The roll, which Carl
+immediately handed to him, he found to contain a number of sheets
+wrapped compactly in a piece of white paper.
+
+"I guess we'll open it and not stand on any ceremony," said Matt.
+
+"Sure!" exclaimed Carl. "For vy nod?"
+
+"It's not exactly the right thing to do. They're not our papers and
+we haven't any business tampering with documents that belong to some
+one else. Under the circumstances, though, and considering that the
+whole affair of the air-ship is a strange one, and that we may be able
+to help the two men in some way through the information the roll may
+contain, we'll have a look at it."
+
+Going back to the place where they had eaten their lunch, the boys
+sat down and Matt opened the little bundle. A dozen blue prints of
+mechanical tracings were revealed. In the center of the roll was a
+sealed envelope, bearing no address or writing of any sort.
+
+"Dere's nodding aboudt der plue prints to helup us know somet'ing,"
+said Carl. "Oben der enfellup, Matt."
+
+"No," returned Matt, "we can't do that. That would be going a little
+too far."
+
+"Vell, ve got to do somet'ing oof ve findt oudt who dose fellers vas."
+
+"We'll wait, and give them a chance to claim their property."
+
+"How dey vas going to glaim it, hey? Dey didtn't dell us who dey vas,
+und ve ditn't dell dem our names."
+
+"We know the air-ship came from South Chicago. I don't believe there
+are very many air-ships in that place, and if we inquire around a
+little we ought to be able to find out who owns the Hawk."
+
+"Righdt you vas! Somevay, Matt, you always know vat to do ven eferypody
+else iss guessing. Shall ve ged indo der car und go pack to der pig
+city py vay oof Sout' Chicago?"
+
+"That's our cue. If we can discover who owns the Hawk we'll leave these
+papers there for him."
+
+Matt rolled up the envelope and the papers and stowed them safely away
+in his pocket.
+
+"I know dere vas some niggers in der vood-pile, all righdt," averred
+Carl. "Two fellers vouldn't go off mit an air-ship dey don'd know how
+to run oof eferyt'ing vas like it ought to be."
+
+"There may be a whole lot of sense in what you say, Carl," replied
+Matt, "and then, again, the explanation of the queer layout may be
+extremely simple. Don't get to imagining things, old chap, but coil
+up that rope and throw it into the car. We'll carry it back to South
+Chicago and leave it at the same place we leave this roll of blue
+prints."
+
+While Carl was coiling up the rope, Matt gave his attention to the
+automobile. When Carl arrived and threw the rope into the tonneau, Matt
+was busy with the crank.
+
+Presently they were in the car and headed back along the return course.
+
+Hardly had they got under good headway, however, when a flurry of dust
+showed in the road ahead of them. As the wind blew the dust aside, a
+horse and buggy with two men broke into view.
+
+In accordance with the rules of the road, Matt slowed down to make sure
+the horse did not take fright at the automobile. The horse was going at
+a run, and the men seemed to be excited.
+
+The one who was driving drew rein as the rig came alongside the car.
+
+"Say," shouted the men, "did you boys see an air-ship anywhere in this
+vicinity?"
+
+"Yes," answered Matt. "It was going south."
+
+"Then we're on the right track?"
+
+"So far as we know; but the air-ship was unmanageable and----"
+
+The men in the buggy did not wait to hear any more. The driver began
+plying his whip and the horse again leaped onward.
+
+"Who were those two men?" yelled Matt, anxious for a little information.
+
+"Thieves!" came the answer, as rig and passengers once more vanished in
+a cloud of dust.
+
+
+
+
+CHAPTER III.
+
+THE BALLOON HOUSE.
+
+
+"Yah!" shouted Carl. "Vat I dell you, Matt? I knew dere vas somet'ing
+der madder! Dem two fellers vas t'ieves, und dey haf shtole der
+air-ship. Py shinks, dey haf got demselufs indo drouple, und it vas
+goot enough for dem. Vat you going to do?"
+
+Matt had begun turning the machine in the road. When he had pointed it
+the other way, he started off at a swift pace on the trail of the two
+men in the buggy.
+
+"We'll try and overhaul those two fellows," answered Matt, "and tell
+them what we know. The information we've picked up may be valuable to
+them."
+
+"Dey don't vas endidled to it," averred Carl. "Vy ditn't dey shtop und
+ask us somet'ings? Anyvay, how can dey ketch a flying machine mit a
+horse und puggy? You mighdt as vell dry to ketch a sky rocket mit a
+papy carriage."
+
+"The Hawk will have to come down," said Matt, "and if those men are
+anywhere near it when it hits the earth they'll be able to recover the
+machine and catch the thieves."
+
+"Oof der machine hits der eart' so hardt as vat I t'ink, it von't be
+vort' nodding, nor der t'ieves neider."
+
+"There's a chance that the rascals will come down safely. If those men
+in the buggy had had their wits about them, they'd have hitched their
+rig to the fence and have jumped into the automobile. We could have
+hustled them over the ground four times as fast as they were going."
+
+A few moments later the boys reached a place where the road branched.
+The horse and buggy were not in sight along either road.
+
+"Vich vay now?" queried Carl.
+
+"It's all guesswork," answered Matt, "but it's always a pretty good
+plan to keep to the right," and, with that, he drove the car along the
+right-hand branch.
+
+After five minutes of fast running, they had not overtaken the rig and
+it was still not to be seen anywhere ahead. The boys knew they had
+been traveling three or four times as fast as the two men were going,
+and that, if they were on the right track, the men should have been
+overtaken long before.
+
+Disappointedly, Matt halted the car and turned it in the other
+direction.
+
+"No use, Carl," said he. "Those men must have taken the left-hand fork
+instead of the right. They're too far away, now, for us to think of
+finding them. We'll hike for South Chicago."
+
+"Dot's der pest t'ing dot ve can do," returned Carl. "Ve'll find der
+owner oof der Hawk und gif him der trag-rope und der bapers."
+
+"We won't find him. He must have been one of those two men in the
+buggy. Probably we can find where he lives, though, and turn the rope
+and the papers over to some one who will give them to him."
+
+"Meppy ve pedder take der shtuff to der bolice, hey? Oof der fellers
+vas t'ieves, dot enfellup mighdt gif der bolice a line on dem."
+
+"There's something in that, too," muttered Matt. "We'll try to find the
+owner of the Hawk, though, before we call on the police."
+
+An hour later, the boys came into South Chicago along a turnpike that
+passed the rolling mills. A man on a motor-cycle was just coming out of
+a fenced enclosure near one of the mills, and Matt halted him for the
+purpose of making a few inquiries. From his looks, the man was of some
+consequence in the steel rail plant, and probably was well-informed as
+to affairs in South Chicago.
+
+"Do you know of any one around here that has an air-ship?" asked Matt.
+
+The question was something of a novelty, and the man laughed as he
+rested one foot on the ground and balanced his motor-cycle upright.
+
+"I suppose air-ships will be thicker'n hops, one of these days," said
+he, "but just now they're about as seldom as hen's teeth. I understand
+there are a couple of men here who are working at air-ships--one
+of them came to the mills to see if he couldn't get some aluminum
+castings. He's got a balloon house about a quarter of a mile down the
+road, on the left. Drop in there and maybe you'll find the man--and the
+ship, too."
+
+Matt thanked the man and followed him slowly as he sputtered off into
+town.
+
+The balloon house, which was plainly visible from the road, was a long,
+high shed, and occupied a solitary position in the midst of a marshy
+field. The doors in one end of the shed, arranged in a series and
+reaching from ground to roof peak, were open.
+
+Leaving the automobile at the roadside, the boys climbed a fence and
+made their way across the flat ground to the big house. On reaching the
+opened doors, one glance showed them that there was no air-ship in the
+shed.
+
+On the earth floor, along one side of the great room, were two or
+three work benches and a litter of wood and metal scraps. There was
+also, in the farther end of the chamber, a number of small tanks,
+presumably used for the manufacture of hydrogen gas. As the boys stood
+in the doorway, two brawny men showed themselves from behind these
+tanks. They wore greasy overclothes and their sleeves were rolled up.
+
+"Get out of here!" yelled one of the men. "We don't allow any reporters
+around this shebang."
+
+"We're not reporters," answered Matt, standing his ground. "Do you keep
+an air-ship here?"
+
+"Well, that's what this big shed is for."
+
+The two men came closer to the boys, one of them filling and lighting a
+cob pipe as he approached.
+
+"Is the name of it the 'Hawk?'" went on Matt.
+
+"Right again," said the man who had been doing the talking.
+
+His eyes were like gimlets, and bored their way into Matt through
+narrow slits.
+
+"Who's the owner of the Hawk?" asked Matt.
+
+"I'm the owner, and my name's Hector Brady. If Jerrold has sent you
+here----"
+
+"I don't know any one by the name of Jerrold. Who is he, and why should
+he send me here?"
+
+The sharp little eyes continued to study Matt.
+
+"Before I say anything more," answered Brady, "you'd better tell me a
+little about yourself."
+
+"I don't know as that's necessary, or----"
+
+"You'd know how necessary it is if you were inventing machines and
+trying to keep your appliances a secret. I'm not the only man in South
+Chicago that's perfecting an air-ship. A fellow named Jerrold has cut
+into the same game, and he has some one nosing around here a good share
+of the time, trying to get wise to something. If Jerrold has sent you
+here----"
+
+"He hasn't," broke in Matt. "I don't know Jerrold from Adam."
+
+"What's your name?"
+
+"King, Matt King."
+
+Brady gave a jump.
+
+"You don't mean to say you're the young Western phenomenon the
+Lestrange people have brought to Chicago to run in that five-day
+automobile race that's turned on at the Coliseum to-morrow?"
+
+"I'm one of their racers," answered Matt. "They have four more in the
+race besides me."
+
+"Well, by thunder!" Brady stood off and regarded Matt as though he was
+a natural curiosity. "Why, you're no more than a kid! They had your
+picture in the paper, after that Kansas race, but you're a heap younger
+than I thought. I guess you've forgotten more about gasolene-motors
+than a whole lot of people ever knew."
+
+"Oh, it isn't so bad as that. I came here to do you a good turn, Mr.
+Brady, and I can't see the sense of raking up my past history. Your
+air-ship has been stolen, hasn't it?"
+
+"Stolen?" Brady gave another startled jump. "Not that anybody knows of.
+Why? What put that in your head?"
+
+Matt was "stumped." He looked blankly at Carl and found that Carl had
+turned an equally blank look at him.
+
+"Where is the Hawk now?" queried Matt.
+
+"She went out on a trial spin with three men in the car. Expect her
+back any moment."
+
+There was a shifty look in Brady's face, and he spoke in a fashion that
+aroused Matt's suspicions.
+
+"Then the Hawk wasn't stolen and you didn't send two men with a horse
+and buggy to look for her?" queried Matt. "We saw the air-ship, but
+there were only a couple of men in the car and the machine was out of
+control. We tried to stop the craft by means of the drag-rope, but the
+rope broke loose and the Hawk got away. One of the men on board dropped
+a roll of papers out of his coat-pocket and we picked it up."
+
+Brady looked at the other man. The glances they exchanged were
+significant, and both swore softly.
+
+"Here's a purty kettle o' fish!" growled the fellow with the pipe.
+"What dy'ye s'pose has happened, Brady?"
+
+Brady muttered something unintelligible, and whirled to Matt with a
+scowl.
+
+"That roll of papers belongs to me," said he. "Just pass 'em over,
+King."
+
+"I don't know whether I ought to give them to you, Mr. Brady, or to the
+police," answered Matt, making no move to take the roll from his pocket.
+
+"Police!" exclaimed Brady. "What the blazes are you talking about? The
+fellow on that car was working for me, and the papers belong to me."
+
+"Then you ought to be able to identify the roll," proceeded Matt,
+coolly. "What did it contain, Mr. Brady?"
+
+"Just papers."
+
+"Typewritten-papers?"
+
+"Well, yes, some of them were typewritten."
+
+"How were they tied up? In a piece of yellow paper?"
+
+"That's it. Hand 'em over. It's queer they got lost out of the car in
+that way, but mighty lucky you picked 'em up."
+
+"I guess you're thinking of the wrong roll," said Matt, coolly. "The
+one you've described isn't the one we found."
+
+"Whether the description is right or wrong, the papers are mine, and
+I'll have 'em!"
+
+Brady, in sudden temper, hurled himself at Matt. The other man, taking
+his cue from Brady, jumped for Carl and grabbed him by the arm.
+
+"Hoop-e-la!" tuned up Carl. "Be jeerful, eferypody! Here's somet-ing
+vat ve ditn't oxbect!" And, with that, the Dutch boy began struggling
+and using his fists.
+
+
+
+
+CHAPTER IV.
+
+THE KETTLE CONTINUES TO BOIL.
+
+
+Both Matt and Carl were well skilled in the art of self-defense. Matt,
+perhaps, was a shade more adept in the use of his fists. Neither of the
+lads, however, had been looking for violence, and the sudden attack of
+Brady and the other man had taken them by surprise.
+
+The two men had plenty of muscle, and Brady was desperately determined
+to secure the roll of papers. The very fact that he was using force to
+accomplish his designs proved that he was not entitled to the papers.
+For that reason, Matt was determined to keep them away from him at all
+costs.
+
+"Hold the Dutchman, Pete!" puffed Brady, hanging to the collar of
+Matt's leather coat and trying to get one hand into the inside pocket.
+
+"Quiet, Dutchy," threatened Pete, as he and Carl swung back and forth
+across the big shed. "I'll strangle ye if ye ain't peaceable. Ye ain't
+got no sense, roughin' things up like--wow!"
+
+At that instant, Carl landed a telling blow on the point of Pete's
+chin. A bushel of shooting-stars must have danced in front of Pete's
+eyes, for the jolt hurled him backward and caused him to claw the air
+in an attempt to keep his balance. He was not more than an instant
+getting the whip-hand of himself, and when he came out of his brief
+daze he was as mad as a hornet.
+
+"I'll kill ye for that!" he yelled, and picked up a heavy hammer that
+lay on the floor.
+
+Pete was between Carl and the open end of the shed; he was likewise
+between Carl and Matt and Brady. The struggle had carried Pete and the
+Dutch boy down toward the middle of the balloon house.
+
+Matt, out of the tails of his eyes, saw the dangerous position in
+which Pete's temper was placing Carl. The young motorist had been
+successfully fending off the attempt of Brady to get into his coat
+pocket; now, thinking Carl might need him, he undertook more aggressive
+measures.
+
+An empty box, which had evidently been used as a seat, stood just
+within the big door. With a sudden lurch, Matt heaved himself against
+Brady and knocked him backward over the box.
+
+As Brady felt himself falling, the instinct to save himself caused him
+to let go of Matt. The instant the young motorist found himself with
+the free use of his fists, he let drive at Brady and still further
+helped him over the box.
+
+With a roar of anger, Brady doubled up on the floor. Matt whirled and
+darted for Pete, reaching that scoundrel just in time to catch the arm
+that was whirling the heavy hammer.
+
+The hammer was wrenched away, and Matt cast it against the wall of the
+balloon house.
+
+"Cut for it, Carl!" cried Matt. "Run for the road!"
+
+"You bed my life!" wheezed Carl. "Dis blace don'd vas gedding fery
+comfordable."
+
+Brady was picking himself up from the floor as the boys rushed past
+with Pete in hot pursuit.
+
+"Get those papers!" yelled Brady.
+
+"I'll git that Dutch kid if it costs me my life!" whooped Pete.
+
+Brady rushed after Pete, and there was a chase across the marshy meadow
+toward the road.
+
+Carl was chunky of build and not nearly so good in a sprint as was
+Matt. Matt was in the lead on the rush from the balloon house, but,
+anticipating that Carl might have further trouble with Pete, he
+slackened his pace.
+
+It was well that he did so. Pete was steadily gaining on Carl and would
+undoubtedly have overtaken him had Matt not executed a quick move with
+an empty salt barrel that lay in the line of flight.
+
+At the right moment, Matt rolled the salt barrel in front of the
+enraged Pete. Pete's shins slammed against it, then he dropped on it
+and plowed up the mucky soil with the top of his head.
+
+So far as the set-to was concerned, it was settled right there, Brady
+being so far in the rear that the boys were able to clear the fence and
+get into the automobile before he could come anywhere near them. As a
+matter of fact, Brady gave up the fight as soon as he had witnessed
+Pete's mishap with the barrel.
+
+As the two chums glided away toward the more thickly settled part
+of South Chicago, they could look back and see Brady assisting the
+disgruntled Pete to an erect position. The barrel had been smashed, and
+Brady was scraping the mud off Pete with one of the staves.
+
+"How you like dot, hey?" gloried Carl, standing up in the automobile
+and shaking his fist. "You vill know pedder der next time dan to make
+some foolishness mit Modor Matt und his bard. Yah, yah, yah!"
+
+Carl wanted to be as tantalizing as he could, but the automobile was
+getting too far away. Sinking down in the seat beside Matt, the Dutch
+boy chuckled blithely.
+
+"Dis has peen a pooty fine leedle trip, Matt," he observed, "und has
+peen full oop mit oxcidement oof a nofel kindt, yah, so helup me. Dot's
+vat I like. I'll bed my life dose fellers t'ink dey vas fell on mit a
+brick house. Vat's der madder mit Prady, anyvays?"
+
+"There's something queer about that air-ship affair," answered Matt,
+thoughtfully. "The two men who rode past us in that buggy said the
+pair in the car were thieves, but Brady didn't know anything about the
+Hawk's being stolen. Brady said, too, that there ought to have been
+three men in the car instead of two. The one who was missing may have
+been the driver. That would account for the poor work the other two
+were making with the engine."
+
+"Ve can make some guesses," said Carl, shaking his head, "aber ve don'd
+know nodding. Dot roll oof bapers don'd pelong to Prady. Vell, oof
+dot's der gase, whose bapers vas dey?"
+
+"That's a conundrum."
+
+"Vill you dake dem py der bolice?"
+
+"I've been thinking of that, and I believe I'll talk with Mr. Harkrider
+before I do anything more. He'll tell us just what to do, and I'm sure
+his advice will be good. You see, Carl, we're not entitled to the
+papers any more than Brady is, when you come to figure the thing down
+to a fine point. If the fellow who lost them out of the car turned up
+and claimed them, we'd have to give them to him."
+
+Mr. Harkrider was superintendent for the Lestrange Manufacturing
+Company, the Eastern representatives of the Jarrot Automobile Company
+of St. Louis. Following the Borden cup race, in Kansas, Matt had
+entered the services of the Jarrot people, and they had sent him to
+Chicago to take part in the five-day race at the Coliseum. While
+waiting for the race to start, Matt and Carl had had the use of any
+machine they wanted in the Lestrange garage, so they had put in their
+time riding around the city and out into the suburbs. That is how they
+happened to be on the road beyond South Chicago at the time the Hawk
+was running away with the two aeronauts.
+
+Unusual experiences always seemed to gravitate toward Matt, and this
+air-ship affair was one of the most novel that had ever come his way.
+What it was leading up to, he did not know, but it was evident there
+was a whole lot more to the matter than appeared on the surface.
+
+After a quick and uneventful run into Chicago, Matt drove the
+automobile into the Lestrange garage and asked for Mr. Harkrider. To
+his disappointment, Mr. Harkrider had left for the day and would not
+return to the garage until the following morning.
+
+"Well," said Matt, as he and Carl left the garage and proceeded toward
+their boarding house, "I guess the delay won't make much difference.
+I'll be busy with the race to-morrow, but you can take the papers,
+Carl, and do with them whatever Mr. Harkrider advises."
+
+It was nearly supper time, and after the boys had had a wash, and a
+good meal, they went up to their room.
+
+Close to eight o'clock, just as they were getting ready for bed, a rap
+fell on the door. Matt answered the summons and found a boy with a
+telegram.
+
+The young motorist had been receiving a great many telegrams, since his
+Kansas victory, and supposed the message must be from some motor-car
+manufacturer who wanted to secure his services.
+
+But he was destined to a surprise.
+
+The telegram had been sent to the Lestrange garage, and by the foreman
+there forwarded to the boarding place.
+
+  "MATT KING, Care Lestrange Company, Chicago:
+
+  "Come immediately to twenty-one-naught-nine Hoyne Street, South
+  Chicago. Important matter relative to runaway air-ship. I will pay
+  your expenses.
+
+                                               "HAMILTON JERROLD."
+
+"More aboudt dot air-ship pitzness," muttered Carl. "Who vas dot
+Jerrold feller?"
+
+"He must be the man that Brady told us about," said Matt. "Jerrold
+seems to be a rival of Brady's, in this air-ship matter, and the
+message looks like a good clue. It won't do any harm to follow it up,
+anyhow."
+
+"Dere iss somet'ing about dot vat I don'd like," demurred Carl. "I got
+some hunches dere iss underhandt vork afoot."
+
+"I know there's underhand work going on," said Matt, "but we've been
+rung in on the deal and have got to see it through. I'm curious to
+learn more about the affair."
+
+"Meppy dot same curiosidy vill make you some drouples," suggested Carl.
+"You can't haf dot, ven der racing iss on do-morrow."
+
+"The Jarrot people have several good men in the five-day race, so it
+won't make much difference if I'm not one of the drivers. Anyhow, I
+don't intend to be all day in South Chicago."
+
+"It don'd look righdt for you to go pack dere alone," grumbled Carl. "I
+vouldn't be easy a minid."
+
+"I am not going alone," laughed Matt. "You're going along, Carl."
+
+The Dutch boy brightened at once and had no more objections to offer.
+
+"Ach, dot's tifferent! Ve vill shdart ad vonce. How ve go? On a pubble?"
+
+"No, we'll take a railroad train. I don't want to go fooling with a car
+at this time of night."
+
+"Is dere a train ve can ketch?"
+
+"Lots of them. South Chicago is a suburb, and we can leave here every
+half hour. We ought to be back by midnight."
+
+Without debating the matter further, the boys started forthwith.
+
+
+
+
+CHAPTER V.
+
+2109 HOYNE STREET.
+
+
+Hoyne Street was easily found. A number of blast furnaces stood so near
+the house the two chums were looking for that the flames from their
+tall chimneys lighted up the surroundings so brilliantly that they
+were able to read the number over the door.
+
+The house was a two-story frame structure. The gas and smoke from the
+neighboring iron mills had shriveled and scorched everything in that
+part of the town. Even by night, and under the glow of the furnaces,
+Hoyne Street had a dismal and dreary appearance.
+
+No. 2109 was set well back from the sidewalk. Two branching wings, in
+front, made the house look like a deserted manufacturing plant. This
+impression was heightened by several broken windows.
+
+There were no lights in the windows other than the reflected glare from
+the high chimneys.
+
+"Whoosh!" muttered Carl, as he and Matt came close to the front of the
+house and read the number. "Dot's der blace, Matt, aber it don'd look
+pooty goot to me. Der feller vat lifs dere don'd got enough money,
+I bed you, to pay for sending dot delegram. Der hen oof drouple iss
+aboudt to hatch somet'ing."
+
+"It may be," answered Matt, who likewise had a queer premonition of
+trouble, "but we've come this far and I'm going to see the thing
+through. If anything goes wrong in that house it will be on account of
+that roll of blue prints. I'll leave the roll with you, Carl, and you
+can stay outside. I won't be in the house more than fifteen minutes at
+most."
+
+"Vell, you look a leedle oudt, Matt, dot's all. Oof somet'ing goes
+wrong mit you, led off a yell und I vill come gallywhooping."
+
+"I don't think anything will go wrong with me if I haven't those papers
+in my pocket."
+
+Carl shivered.
+
+"Chee, but der leedle fires on der chimneys iss prighdt. Somet'ing
+aboudt dis blace gifs me a creepiness oof der skin. Be jeerful, be
+jeerful! Don'd shday in dere longer as den minids, Matt, oder I vas
+likely to t'row fits."
+
+"I'll come out as soon as I can, Carl," answered Matt. "Don't fret. I'm
+able to take care of myself in a pinch."
+
+"Oof you see der pinch fairst, yah, I bed you! Aber oof der pinch come
+ven you don'd vas looking, den vat?"
+
+Matt laughed as he turned away, climbed a short flight of steps and
+drummed on the front door. He had to rap three or four times before his
+summons was answered.
+
+A light showed itself through a fan-shaped transom over the door, and a
+hand could be heard fumbling with a rusty bolt. In a minute or so the
+door was drawn open and a girl stood revealed. She carried a lamp with
+a smoked chimney, and one of her slender hands protected the flame from
+the draft.
+
+She was eighteen or nineteen years old, and, in spite of her coarse
+calico gown, she was extremely pretty. Her prettiness, however, was
+not what impressed Matt. The first thing he noticed was that the hand
+shielding the lamp was trembling. Lifting his eyes to the girl's face,
+he observed that she wore a frightened look.
+
+"Does Mr. Jerrold live here?" Matt asked.
+
+The girl stared at him; her lips moved, but no sound came through them.
+Matt repeated the question.
+
+"Y-y-yes," faltered the girl.
+
+"My name's King," answered Matt. "Mr. Jerrold sent me a telegram and
+asked me to come here to-night."
+
+The girl leaned forward eagerly as though she would say something.
+Before she could speak, if she had intended to, a sound as of some one
+moving in the darkness behind her, caused her to draw back.
+
+"Please come in," she said breathlessly.
+
+Matt entered the hall. The girl closed the door behind him and then,
+with the lamp shaking in her hand, led him into a room off the hall.
+
+The room was evidently a parlor, although its furniture was meager and
+shabby.
+
+"Please sit down," said the girl, placing the lamp on a table. "Mr.
+B--Mr. Jerrold will be here in a few moments. Would you like to read
+while you're waiting?"
+
+Matt started to decline, but the girl had already picked up a book from
+the table, opened it and was handing it to him.
+
+He looked at her in astonishment. From her frightened face his eyes
+fell to the book that was quivering in her hand. There was an appeal in
+her manner which caused him to take the book.
+
+"Thank you," said he.
+
+The book was opened at the fly leaf. On the leaf was written the
+following:
+
+  "You are trapped. I would have warned you, if I could, but he would
+  have killed me. Now you are in the house, you can't get away. Do
+  whatever you are told to do and all will be well. Lay the book back
+  on the table, and don't let any one know what you have read here."
+
+Matt was astounded. Trapped! And he had walked into the trap with his
+eyes wide open!
+
+Who was the girl and why had she run the risk to warn him? And what
+good was her warning to do if he did not take advantage of it and make
+his escape?
+
+  "Now you are in the house, you can't get away."
+
+He read those words again, and after he had read them he looked about
+the room curiously. There were two windows in the room and they were
+screened with thick curtains. Matt, however, could see no one. If the
+trap had been sprung where were the ones who had sprung it?
+
+He realized that if he made an attempt to get out of the house now,
+those who had entrapped him would immediately conclude that the girl
+had given him a warning. Thus he would not only fail to get away, but
+would bring punishment upon the girl for her attempt to help him.
+
+  "Do whatever you are told to do and all will be well."
+
+He read that over again and made up his mind that he would follow the
+advice. He laid the book back on the table, and, just at that moment,
+the girl re-entered the room.
+
+"I have read that book," said he.
+
+"Here's a newspaper," said she.
+
+As she held the paper in front of him she pointed to an article,
+evidently intending that he should read it.
+
+The girl was a mystery to Matt. From her manner there was no doubt
+about her being anxious to do whatever she could to shield him.
+
+Leaving the paper in his hands, she walked over to the table, opened
+the book and deftly extracted the fly leaf. Then she vanished from the
+room once more.
+
+Matt drew his chair closer to the table so that he could get the full
+benefit of the dim light.
+
+The first thing he noticed was that the paper was a week old. It was a
+Chicago daily. The column to which the girl had called his attention
+was headed, "Burglaries Continue! Astonishing Series of Robberies in
+South Chicago are Still Kept Up! Thieves Make Off With Loot and Leave
+Not a Clue Behind! Police Authorities Baffled! Latest Victims Hartz &
+Greer, Jewelers!"
+
+Here followed an account dealing with a number of mysterious
+burglaries, but Matt, because of the danger in which he found himself,
+did not give the article the attention he would otherwise have done.
+
+He did wonder, however, why it was that the girl had pointed out the
+article to him. While he was wondering, a step sounded in the hall and
+a form showed itself in the hall door.
+
+The man was Brady!
+
+Matt sprang up. Brady came into the room with an easy air and gave vent
+to a short laugh.
+
+He was quite a different looking man when out of his greasy
+overclothes, but there was no doubting his identity. Matt's fist had
+left a bruise on the side of Brady's face, and the spot was covered
+with a square of court-plaster.
+
+"Surprised?" queried Brady, dropping into a chair.
+
+Before seating himself he was careful to draw the chair in front of the
+hall door.
+
+"Were you the one who sent me that telegram?" asked Matt.
+
+"Guilty!" was the chuckling response. "You were expecting to meet
+Jerrold, eh? I was a little in doubt as to whether you'd bite at the
+bait, but took a chance. You're a mighty accommodating young fellow,
+King. Why, you came all the way out here, at this time of night, just
+to give Jerrold those papers! Didn't it strike you as being a little
+bit queer that Jerrold should have asked you to come and see him when
+it was his business to go and see you? And then, again, how did you
+think Jerrold got hold of your name and address? Oh, well, you've a lot
+to learn yet, my lad."
+
+"I'm learning you pretty fast, Brady," said Matt. "You have fooled me,
+but you've gained nothing by it."
+
+"I think I have," was the other's cool reply.
+
+"You'll not get that bundle of papers."
+
+"No? Haven't you got them with you?"
+
+"I left them where they'd be safe."
+
+"Then you suspected there was something a little off-color about that
+telegram?"
+
+"Yes."
+
+"Plucky boy! Nevertheless, you dropped into my trap, and that's the
+main thing. Those papers cost me a good deal of scheming, and if you
+were really thoughtful enough to leave them in a safe place, I'm mighty
+sorry."
+
+"You can search me," said Matt, "if you're not willing to take my word."
+
+"I'll search you quick enough."
+
+"Then hurry up; I want to get away from here."
+
+"Those papers are not the whole of it," went on Brady. "I want to make
+you a proposition, King. I need a motorist for the Hawk, and I think
+you'd about fill the bill. How would five hundred a month strike you?"
+
+"Five thousand a month wouldn't strike me. In the first place, Mr.
+Brady, I don't like your methods and wouldn't work for you at any
+price; and, in the next place, I am already in the employ of the
+Lestrange people."
+
+"You'll work for me all right whether you like my methods or not."
+There was an ugly look in Brady's eyes and an ugly note in his voice.
+"You're just the sort of youngster I need, and now that I've got a grip
+on you I don't intend to let you get away."
+
+"It takes two to make that sort of a bargain!"
+
+Matt had edged around toward one of the windows with the intention of
+making a break through the door.
+
+Brady got up.
+
+"What are you waiting for, Pete?" he called.
+
+Matt turned a quick gaze about him, wondering from which direction Pete
+was to appear. Then, quick as a lightning flash, the curtain behind him
+gave way and fell in smothering folds over his head and shoulders. Two
+brawny arms encircled him like the jaws of a vise.
+
+He fought with all his strength, and tried to yell to Carl. But one
+effort was as ineffectual as the other.
+
+Pete and Brady had him between them, and he was utterly powerless.
+
+
+
+
+CHAPTER VI.
+
+CARL INVESTIGATES.
+
+
+Carl hated a "waiting" game. If there was anything going on, he liked
+to be right in the midst of it. On top of all this, he was vaguely
+suspicious of everything connected with that telegram.
+
+When Matt went up and knocked on the door of the house, Carl was hoping
+the summons would not be answered; but when the door opened, and Matt
+disappeared inside the house, Carl's real worries began.
+
+Pacing back and forth on the walk, the Dutch boy impatiently counted
+the seconds and checked off the minutes. No sound came from the
+building, and, after the light had vanished from the hall, not a ray
+was to be seen at any of the windows.
+
+"I t'ink, py shiminy," muttered Carl to himself, "dot der fifdeen
+minids vas oop. Vell, I count off fife more schust for goot measure.
+After dot, oof Matt don'd come, I vill make some infestigations."
+
+Owing to the lateness of the hour, and the obscure section of the town
+through which that part of Hoyne Street ran, no one passed the front of
+the house. Carl's solitary vigil was not relieved by the sight of any
+chance traveler.
+
+Mentally he checked off another five minutes. During the counting
+he fancied he heard a noise in the house, but it was so muffled and
+indistinct he could not be sure. Matt did not show himself, and Carl
+started his investigations.
+
+His first move was to run up the steps and pound on the door. Although
+he made enough noise to wake the entire neighborhood, he couldn't
+bring anybody to the entrance. He tried the knob, but found the door
+fastened. Then he hurled his weight against the door in the hope of
+breaking it in. The door must have been in better repair than the rest
+of the house, for it withstood his attack with scarcely a shiver.
+
+Carl's temper was always pretty close to the surface, and his failure
+to get into the house caused him to forget his forebodings on Matt's
+account and to get good and mad on his own.
+
+"I vill find Matt oof I haf to preak down a vinder!" fumed Carl,
+jumping down from the steps and starting to run around the side of the
+house.
+
+"Hello, there!" shouted a voice most unexpectedly from the sidewalk.
+"What're you up to, hey?"
+
+Carl halted and looked around. In the glow of the furnace fires he saw
+a man standing in front of the house.
+
+"Vat iss it your pitzness?" he snapped. "I'm going to ged indo dot
+blace oof I haf to preak holes in it!"
+
+"I'll make it my business, quick enough!" called the other. "Come here,
+and be quick about it."
+
+There was authority in the voice, and the command was accompanied by a
+backward sweep of the hand under a long coat. When the hand reappeared,
+there was a glimmering object clutched in the fingers. The light also
+glimmered on two rows of buttons on the speaker's coat.
+
+"Ach, du lieber!" muttered Carl. "You vas an officer, hey?"
+
+"Come here, quick!" ordered the man. "Tell me where that balloon came
+from. It seemed to rise from around in this vicinity somewhere."
+
+By that time, Carl had reached the walk. The officer pointed upward,
+and Carl's eyes, following the finger, saw an air-ship clearly outlined
+against the glow of the blazing chimneys. The cigar-shaped gas-bag and
+the pendent car stood out plainly. The front end of the air-ship was
+pointed upward, and it was vanishing swiftly into the night.
+
+"Himmelblitzen!" gasped Carl. "Dot vas der Hawk! It must be der Hawk!"
+
+"Hawk, eh?" returned the officer. "What do you know about it? The thing
+seemed to rise up in the air from around here."
+
+"Iss dot so?" cried Carl, excitedly. "Vell, I ditn't see him, und dot's
+righdt. I vas drying so hardt as anyt'ing to ged indo der house."
+
+"I heard you tryin' to break in the door. Don't you know it's against
+the law to do that?"
+
+"I don'd care for der law! My bard vent indo dot house und left me to
+vait. Ven I vait plendy long enough for him und he don'd come, den I
+make some infestigations. No vone answers my knock on der door, und for
+vy iss dot?"
+
+"You say a friend of yours is in the house?"
+
+"Sure! Don'd I vas delling you?"
+
+"When did he go in?"
+
+"Haluf oof an hour ago--all oof dot."
+
+The officer began questioning Carl and got from him pretty near the
+whole of the affair--Matt's name and occupation, the experience with
+the air-ship in the early part of the afternoon, nearly everything
+concerning the roll of papers, the receipt of the telegram, and the
+night visit of the boys to South Chicago.
+
+This policeman was an intelligent member of the force, and he at
+once concluded that here was a matter which called for official
+investigation.
+
+"We'll get into the house and find out about your friend," said he.
+"Your yarn is a queer one, but has the true ring, and it's evident
+there's shady work of some kind going on."
+
+"Shaty vork? Vell, you bed you! Vere iss Matt? Dot's vat I vand to know
+vorse as anyt'ing else. I ditn't vant him to go in dere, anyvay, aber
+ven he makes oop his mindt to do somet'ing, den it vas as goot as done
+und vat I say don'd cut some ice."
+
+"If he's in there we'll get him," said the officer, decidedly.
+
+As a preliminary to more drastic operations, he went up to the door
+and pounded on it with his night-stick. The summons, although several
+times repeated, was not answered. Thereupon the policeman and Carl,
+throwing their united weight upon the door, burst the bolt from its
+fastenings and tumbled into the hall.
+
+The darkness of the interior was relieved only by the glare of the
+furnaces coming in at the transom. Silence reigned everywhere.
+
+"I don'd like der looks oof t'ings," muttered Carl, forebodingly. "Dere
+don'd vas anypody ad home now, aber ven Matt come in dere vas plendy
+oof people here. Vat toes it mean, officer?"
+
+"We'll try and find out what it means."
+
+There was an electric dark lantern at the policeman's belt. Taking the
+lantern in his hand he switched on the light and sent a bright gleam
+into every nook and corner of the hall.
+
+No sign of Matt, nor of any of the occupants of the house, was
+revealed. There were only two or three rooms furnished on the lower
+floor, and none at all on the floor above. Every part of the house was
+searched, and the last place of all to pass under the policeman's and
+Carl's scrutiny was the shallow basement.
+
+It was evident to both searchers that people had been in the house up
+to a very recent moment, for in one of the first-floor rooms there
+remained an odor of tobacco smoke, but there was no living person
+anywhere in evidence.
+
+"Don'd dot peat ter tickens?" murmured Carl. "Matt come in der front
+door, und he ditn't come oudt oof it. Oof he vas daken away it must haf
+peen py der pack oof der house. Meppy ve pedder haf a look ad der pack
+yardt?"
+
+"Wait a minute," answered the officer.
+
+Bending down he picked some object off the floor and examined it under
+the rays of the lantern. An exclamation of surprise and wonder fell
+from his lips.
+
+"Vat it iss?" queried Carl.
+
+"Here's the biggest kind of a find!" was the response. "Thunder! this
+must be my lucky night."
+
+"How you figger dot?"
+
+"This is a canvas bag."
+
+"Yah, I see dot, aber it ditn't pelong by Matt und it don'd dell us
+nodding aboudt vere he vas."
+
+"It's marked 'Hartz & Greer, Jewelers,'" went on the policeman, his
+voice shaking with excitement. "That's a firm doing business right here
+in South Chicago, and their store was burglarized mysteriously a little
+more than a week ago. Some fifteen thousand dollars' worth of jewelry
+and diamonds were taken, and this," the officer shook the canvas bag,
+"_this_ is the first clue any one has found to the robbers!"
+
+"Shiminy Grismus!" muttered Carl. "Dis must haf peen der blace vere der
+t'ieves hat deir hang-oudt. Aber dot don'd got some interest for me.
+Vat I vant to know iss, vere iss Modor Matt? Dis pitzness iss gedding
+on my nerfs aboudt like dot odder time ven he tissabeared schust pefore
+der cup race. Shtick der pag in your bocket, officer, und led's haf
+some looks at der pack yardt."
+
+The policeman, now wrapped heart and soul in the hunt, put the bag away
+in the breast of his coat.
+
+The door leading into the back yard, as they had already discovered,
+was unlocked. The rear premises were enclosed by a high board fence,
+and the beacons that capped the neighboring chimneys lighted the
+enclosure sufficiently so that the lantern was not needed.
+
+There was a very perceptible odor of gasolene in the back yard. The
+moment Carl sniffed it, he gave vent to a stifled yell and grabbed the
+policeman's arm with both hands.
+
+"What's to pay now?" demanded the policeman.
+
+"Der air-ship!" gasped Carl.
+
+The officer threw a startled look at the sky.
+
+"No, no, it ain'd oop dere," went on Carl. "It vas in dis pack
+yardt--yah, so helup me! Der gasolene used in der modor make der
+shmell. Don'd you ondershtand? Dey filled der tank here, und shpilled
+some oof der gasolene! Dose fellers haf run off from dis blace mit
+Matt, und dey have dook him along. Ach, himmelblitzen, vat a luck!"
+
+
+
+
+CHAPTER VII.
+
+JERROLD, BRADY'S RIVAL.
+
+
+"Thunder!" cried the policeman, catching the Dutch boy's drift, "you're
+right, as sure as my name is Sam Harris! Your friend went off in that
+air-ship."
+
+"He ditn't vent," protested Carl, in a temper, "he vas dook."
+
+"Well, he was carried off in the thing, no matter whether he went of
+his own free will or was taken by force. If we each of us had a pair
+of wings we might follow the flyin' machine, but we ain't got 'em, so
+we'll have to do what we can on the ground."
+
+"Dere iss a palloon house oudt on der roadt py der rolling mills,"
+suggested Carl. "Meppy der Hawk vas dere. Dot's vere Prady keeps him
+ven he ain'd sky-hootin' t'roo der clouds. Meppy ve go und take a look
+at der palloon house, eh?"
+
+"I know the place, and it won't do any harm to go there and look--but
+the fellow who ran off with your friend would be foolish to drop down
+there."
+
+"Vell, foolish or nod, ve look efery blace vat ve can."
+
+The balloon house was not a great way from that part of Hoyne Street,
+and Harris and Carl reached it after a cross-lots walk of five minutes.
+
+They found the great doors open, but there was no air-ship in the place
+and no one on watch around it. Furthermore, an examination of the
+interior showed that an extensive clean-up had been made of the various
+tools which Matt and Carl had seen in the place during the afternoon.
+Everything of value had been removed.
+
+Carl explained all this for the officer's benefit.
+
+"It's a cinch the owner of the air-ship has changed his headquarters,"
+commented Harris. "Brady, you say, the fellow's name is? Well, he's
+an inventor. One of his inventions is a patent 'jimmy'--which, of
+course, he wouldn't dare to patent. We've been watching his air-ship
+operations, here in South Chicago, but they seemed straight and
+legitimate enough."
+
+"Do you know dot feller, Hamildon Jerrold?" asked Carl.
+
+"Sure, I know him. He's all right, Jerrold is, although everybody looks
+on him as a harmless sort of crank."
+
+"He don'd lif in dot blace vere der chimney fires iss?"
+
+"No; he hangs out in a different part of town."
+
+"Den, you see, it vas a put-oop chob all aroundt. It vas Prady, I bed
+you, vat sendt dot delegram, got Matt in a drap, und den flew off mit
+him in der Hawk. Meppy ve make a call on Jerrold?"
+
+"I'll call up the department and report," said Harris, "so they can
+send another man on my beat while I'm fooling around on this case."
+
+They hurried back into town and the officer unlocked one of the
+lamp-post boxes and reported to headquarters.
+
+"All right," said he as he rejoined Carl. "Now we'll put in the rest of
+the night, if we have to. If Brady has had a hand in the robberies that
+have been going on here, this is liable to be good and profitable work
+for me."
+
+Jerrold lived almost a mile from the place where Harris had done his
+telephoning. He had a large, rambling old house set far back in a dense
+mass of trees and shrubbery.
+
+"He's a good deal of a hermit," explained Harris, as he and Carl
+proceeded along the walk to the front door. "A harmless old skate, but
+he's pretty broad between the eyes, at that."
+
+It was after midnight, and, as might be supposed, the house was dark. A
+knock on the door brought a night-capped head from an upper window.
+
+"Who's down there?" demanded a voice. "Is it you, Payne?"
+
+"No, Mr. Jerrold," answered Harris, "it's a police officer. I've come
+to see you on important business."
+
+"Have you found the Hawk?" cried Jerrold; "did you get back the plans
+those rascals stole from me?"
+
+"Come down and let us in," said the officer. "We want to talk with you."
+
+"Wait a minute."
+
+The head was withdrawn and the window dropped. A little while later,
+the front door opened and Jerrold showed himself, carrying a candle.
+Carl recognized him as one of the two men who had been pursuing the
+Hawk in the buggy.
+
+"Don'd you know me, Misder Jerrold?" asked Carl.
+
+The inventor stared at him and shook his head. Thereupon Carl explained
+where and when they had met. Jerrold's brows wrinkled in a frown.
+
+Leading his callers into a small sitting room he asked them to sit down.
+
+"What do you know about this fellow Brady, Jerrold?" asked Harris, by
+way of getting at the business in hand.
+
+"I know he's a scoundrel!" declared Jerrold with emphasis. "He's a good
+mechanic, though, and in spite of his shady record I took him on here
+to help me build my air-ship, the Eagle. After he had been with me for
+a while, I found he was stealing my ideas and building an air-ship of
+his own. Then I discharged him. Since then he's been attending to his
+own operations and I have been attending to mine. There are several
+important points about my machine, though, which Brady has been anxious
+to discover. He has tried to bribe Payne, the man who works for me, to
+give up a set of my blue prints, and he has tried to get them in other
+underhand ways. At about eleven o'clock, yesterday, three of Brady's
+men tried out-and-out robbery. That safe was forced"--Jerrold pointed
+to a small steel safe in one corner of the room--"and the roll of blue
+prints taken out. Payne and I were in the workshop at the time. We had
+just put the finishing touches to the Eagle and were inflating the bag
+for a trial. I heard a suspicious sound from the house and ran into
+this room. One of the thieves had just cleared an open window, another
+was getting out and the third was making ready to go. I had a wrench
+in my hand and I hurled it at the man in the room. He dropped without a
+groan. Payne came, just then, and we went after the other two. Brady's
+air-ship was waiting for them in the rear of the house, and the two
+robbers got into it and were away before we could catch them. Payne
+and I got a horse and buggy, as quick as we could, but by that time
+the air-ship was no more than a speck in the sky, off to the south. We
+followed, keeping the course the air-ship had taken. The men aboard
+didn't seem to know how to handle the craft very well, and I was hoping
+some accident would happen, that the craft would come down and that I
+would be able to get back my blue prints."
+
+Jerrold halted for a little, his face flaming with anger and
+indignation.
+
+"I haven't my patents, yet," he went on, in a few moments, "and haven't
+even been able to establish a caveat, so, you see, if Brady should
+get ahead of me at the patent office he would snatch a fortune out
+of my hands. For," and here the inventor threw back his head with
+laudable pride, "I claim to have invented an air-ship that can be
+used for commercial purposes--the first machine of the kind that will
+successfully navigate the air against the strongest wind that blows.
+But if that scoundrel Brady takes from me the fruits of my toil, I
+shall be ruined!"
+
+Jerrold's body slumped forward in his chair, and he crouched there in
+an attitude of extreme dejection.
+
+"Where's the fellow you knocked down with the wrench?" asked Harris,
+his professional mind dealing with the more practicable aspects of the
+case.
+
+"When Payne and I got back to the room, after pursuing the other two
+rascals to the Hawk," answered Jerrold, "the man had vanished. I
+suppose he recovered from the effects of the blow and took himself off."
+
+"He vas der feller vat drove der modor in der Hawk," explained Carl,
+"und ven he vas pud down und oudt, der odder fellers made poor vork oof
+triving der machine. Aber dot ain'd vat I got on my mindt, schust now."
+Carl pulled the roll of blue prints from his pocket. "Dere, Misder
+Jerrold," said he, "iss vat you lost. Take it mit der gombliments
+oof Modor Matt--my bard who iss gone I don'd know vere. Oof you hat
+shtopped a leedle in der puggy, und toldt us vat I haf heardt schust
+now, den, by shinks, you vould haf got der bapers pack a long dime ago."
+
+A cry of delight broke from Jerrold's lips. For a moment he stared at
+the roll, then swooped down on it with both hands, caught it away from
+Carl and began removing the wrapper with trembling fingers.
+
+"Here they are, here they are," he crooned joyfully, pawing the blue
+prints over and counting them, one by one; "they're all here, and----"
+
+He stopped short and stared blankly at the envelope, which had fallen
+out of the blue-prints and dropped on the carpet.
+
+"What's that?" asked Harris.
+
+"I don't know," replied Jerrold; "it's nothing of mine and wasn't in
+the safe, to my recollection, at the time the blue prints were taken."
+
+"Well, it may be yours, for all that. If it was in the roll, it stands
+to reason it must have been in the safe. Better open it. Probably you
+can tell from the contents whether it is yours or not."
+
+Harris picked up the envelope and handed it to Jerrold. The latter
+took it from him with a puzzled expression on his face.
+
+"I'm pretty sure this isn't mine," said he, turning the envelope over
+and over.
+
+"Well, you've got to be absolutely sure," returned Harris.
+
+Jerrold, thus urged, tore open the envelope, drew out the sheet and
+cast his eyes over it.
+
+"No," he declared, "it doesn't belong to me. The thieves must have put
+it in with the blue prints."
+
+"Let's have a look at it," said the officer.
+
+Drawing closer to the candle, Harris proceeded to read the letter.
+While he read, his face brightened and a look of surprise and
+exultation rose in his eyes.
+
+"Another clue, and a hot one!" he cried. He whirled on Carl. "With this
+as a guide," he went on, "it's dollars to doughnuts we can trace your
+friend and get him away from that scoundrel, Brady!"
+
+"Ach, vat a habbiness!" expanded Carl. "Readt it oudt to me, Harris,
+und be kevick ad it."
+
+
+
+
+CHAPTER VIII.
+
+JERROLD'S GRATITUDE.
+
+
+"The letter," explained Harris, "was written by Brady, and was
+evidently entrusted to the men in the Hawk for delivery to some one
+else. It's full of pointers, and a slicker bit of evidence it would be
+hard to find. And to think how it dropped into the hands of Motor Matt!
+The whole affair sounds like a 'pipe.'"
+
+"Tell me about that!" cried Jerrold, his shock of joy having passed and
+left him leisure for other things. "Who is this Motor Matt, and how did
+he happen to get hold of the blue prints?"
+
+"Ve vill go ofer dot lader, Misder Jerrold," said Carl, impatiently.
+"Schust now, dough, I vant to hear vat der ledder say. Readt him oudt,
+Harris! I vas so uneasy ofer it I don'd vas aple to sit shdill."
+
+"It's addressed to a man called Whipple," went on Harris, "and here's
+the way it runs:
+
+  "'Grove, Needham and Harper, with one of my improved jimmies, are
+  going to make another try for those blue prints of Jerrold's. If they
+  get them--and I think they can, for our plans are well laid--they'll
+  carry the papers to Willoughby's swamp in the Hawk and leave them
+  with you. We will quit our operations in South Chicago, clean out the
+  balloon house (I have already sold the building for old lumber) and
+  make our future headquarters in the swamp. It will be safer there.
+  After we improve the Hawk according to Jerrold's plans, we will
+  have a ship in which we can go anywhere, and with which we can do
+  anything. All we need is a competent motorist--Harper's good enough
+  for an amateur, but we need a professional. I'll try and bring one
+  with me, when I come. Meanwhile, until I show up at the swamp, I want
+  you to take good care of the blue prints.
+
+                                                         "'H. B.'"
+
+A great light dawned on Carl during the reading of the letter--a light
+so strong that it left him blinking.
+
+"Py chimineddy," he gurgled, "I know now vy dot Prady run off mit
+Matt! He say in der ledder dot he vants some brofessional to run dot
+air-ship. Vell, Matt knows more as anypody aboudt modors, und so Prady
+dook him off. Vat a high-hantet pitzness! Und Prady has captured a
+hornet oof he dit pud know it! He vill t'ink he has a handtful ven he
+dries to make Matt vork for him."
+
+"From this," proceeded Harris, waving the letter, "it seems that Brady
+had already laid his plans to quit South Chicago. In the letter,
+over his own signature, he admits sending three of his men to steal
+the blue prints. By a chance, and owing to the course of events in
+keeping the driver of the air-ship from getting away with the other two
+thieves, this roll and the letter dropped into the hands of Motor Matt.
+Undoubtedly, Motor Matt has been taken to Willoughby's swamp."
+
+"Und vere iss dot?" asked Carl.
+
+"I know about the swamp," went on Harris, "for I helped some Chicago
+officers run down a couple of escaped prisoners there, once. It's a
+bad hole, but there is a sort of island in the middle of it that has
+been the resort of criminals for a good many years. To get through the
+water, and mud, and tangled bushes to the island is a hard job for any
+one who has to go on foot. Still, it can be done. Brady and his men, of
+course, can use the Hawk, and all they have to do is to sail through
+the air and drop down where they want to go. The difficulties of the
+swamp won't bother them at all. The place is about four miles from Lake
+Station, Indiana."
+
+"Vell," said Carl, eagerly, "led's go dere. Der kevicker vat ve go, der
+kevicker vat ve can helup Matt. He iss my bard, und he needs me now."
+
+The Dutch boy got up and started for the door. Bounding from his chair,
+Jerrold overtook him and grabbed his arm.
+
+"Wait!" he commanded, "I've only got a faint grasp of the situation,
+but from what I can figure out you're going to need me. First, though,
+I want to hear all about this Motor Matt. He has done a whole lot for
+Hamilton Jerrold, and Jerrold is a man who always tries to pay his
+debts. Tell me how the blue prints got into the hands of Motor Matt."
+
+"Aber ve vas in a hurry!" cried Carl. "Villoughpy's svamp iss a goot
+vays off, und----"
+
+"You'll save time in the end by losing a little here and now," averred
+Jerrold, drawing Carl to a chair and pushing him down into it. "Go on!
+Give me the whole of it, between you, and be quick."
+
+There was a compelling note in the inventor's words and manner, that
+demanded attention. Carl yielded and struck into an explanation of the
+events of the preceding afternoon. Whenever his impatience led him
+to skip any of the details, Harris, who recognized the advantage of
+letting Jerrold know everything, picked up the ignored detail and made
+Carl go over it.
+
+Jerrold's interest and excitement increased as he listened. When Carl
+described how he and Matt had fought with Brady and Pete at the balloon
+house and kept them from getting the blue prints, Jerrold clapped his
+hands and shouted "Bravo!" And when Carl told of the bogus telegram
+that had brought the boys to South Chicago, Jerrold's face clouded with
+indignation and anger.
+
+"Motor Matt," declared Jerrold, when Carl had finally finished, "has
+done a lot for me, and he's going to find that Hamilton Jerrold knows
+how to be grateful. I agree with Harris that there is hardly a doubt
+but that Brady has taken young King to Willoughby's swamp. Brady wants
+the young motorist for the Hawk, and intends to have him, whether or
+no. According to Harris, the swamp's a difficult place to get at for
+those not equipped with an air-ship. That's where I come in. This way,
+friends!"
+
+With that, the inventor caught up his candle and led the way through
+the house and out at a back door.
+
+By then it was nearly three o'clock, and the very darkest part of the
+night. A gust of wind blew out the candle, which had been about as
+effective as a glow-worm, and the three were left at the foot of the
+rear steps staring at a fluttering expanse of canvas.
+
+The canvas formed a sort of V-shaped tent, long and high and secured
+with many guy-ropes. Because of the darkness it was difficult to get
+any kind of an idea as to the size of the tent, but that was a minor
+point.
+
+"I'll have to get a lantern," said Jerrold. "Wait a minute."
+
+"I've got a dark lantern, Jerrold," interposed Harris, "and I guess
+that will do."
+
+"Fine!" exclaimed Jerrold, as Harris switched on the current and swung
+the beam of light around him. "This way," the inventor added, and
+ducked through the end of the tent.
+
+In the gloomy interior a weird sight was disclosed--something so new
+and novel as to send an uncanny sensation along the nerves of Carl and
+Harris.
+
+Here was another cigar-shaped gas-bag, and another suspended car. The
+car itself was stationary, but the bag, because of the drafts that
+surged through the tent, was bobbing and swaying like some monster,
+anxious to be unleashed.
+
+The flickering gleam from the dark lantern could only disclose a part
+of the air-ship at a time.
+
+"Ach," muttered Carl, "dot makes my nerfs shake und shake like
+anyt'ing. Sooch a horrible t'ing vat it iss!"
+
+"That's because you're not familiar with such a craft," said Jerrold.
+"Payne and I have worked over it for years, and only yesterday saw the
+completion of our labors. It was six o'clock last night before the bag
+was fully inflated. We had to use common illuminating-gas, too, and
+the not more buoyant hydrogen. I have called the air-ship the 'Eagle,'
+and if you sweep that light along the side of the bag you will see the
+name."
+
+This was a bit of byplay that took time and was utterly needless, but
+a great pride throbbed in the inventor's words, and even the smallest
+detail of the air-ship was fraught with the utmost importance to him.
+
+"Everything about the craft," Jerrold went on, "is of the very
+best. The motor is the lightest, strongest and most powerful ever
+constructed. The car will carry half a dozen, easily. Sand-bags are
+suspended from each end of the gas-bag. When I pull in the sand-bag at
+the front end, the equilibrium is displaced, the bag points upward, and
+the propeller forces the air-ship to rise. So, when I wish to descend,
+I pull in the sand-bag at the rear point of the bag. When both bags are
+hanging loose, the Eagle swims in the air on an even keel. Now, the
+steering rudder, which also helps in maneuvering the ship, is a little
+idea of my own and----"
+
+"Ach, hang der shdeering rutter!" broke in Carl, impatiently. "Harris
+und I haf got to go afder Matt und ve can't vait aroundt here any
+longer. Ve haf got to go py dot svamp, und----"
+
+"Exactly!" broke in the inventor. "The Eagle, fully inflated and with
+a tank full of gasoline, is waiting for a trial spin in the morning.
+I have the honor to propose that we use the craft now, proceed to
+Willoughby's swamp and rescue Motor Matt. That will save time, and a
+whole lot of hardships in forcing your way through mud and water and
+tangled brush in order to reach the island."
+
+Harris had already gathered the inventor's idea, even before he
+began putting it into words; Carl, however, had not anticipated the
+suggestion, and he was dazed by it.
+
+"You mean to dake us py der svamp in der Eagle?" he asked, in some
+trepidation.
+
+"Yes."
+
+"Ach, himmel! I nefer rode mit a air-ship. Vill I be seasick py it?"
+
+"I don't think so. You see, I have never navigated an air-ship myself,
+but I'll bank on the Eagle doing its work. I can run the engine."
+
+"Vat oof it shouldt durn oopside town mit us vile ve vas a mile in der
+air?"
+
+"I'll guarantee it won't do that."
+
+"Vell, vedder or nod," said Carl, "I am going afder my bard. Oof der
+tangers vas greadt, I take dem; und oof dey vasn't so greadt, den I
+take dem, too. Matt vouldt do more as dot for me, yah, I bed you!"
+
+Harris was also afflicted with doubts.
+
+"The ground has always been good enough for me, Jerrold," said he, "and
+whenever I get my feet off it and go up any distance I have a bad case
+of vertigo. If I should get dizzy and fall off the car----"
+
+"You won't," interrupted the inventor; "people never get dizzy in
+balloons."
+
+"You're sure it won't tip over and spill us out?"
+
+"Positive."
+
+"You don't know much about it yourself, you know, having never been up
+in it."
+
+"That scoundrel, Brady, has used the Hawk with fair success, and the
+Hawk is modeled on the same lines as the Eagle, only the Eagle has
+improvements which Brady was not able to get hold of and put on his own
+machine. Shall we go to the rescue of Motor Matt? Come, my friends,
+time is flying."
+
+"Und ve ought to be flying, too," said Carl, now eager to make the
+ascension.
+
+"I'll take a chance," observed Harris.
+
+"Good!" applauded Jerrold.
+
+The next moment he had vanished in the darkness and could be heard
+pulling at some ropes. In less than a minute the entire top of the tent
+fell away, revealing the stars.
+
+"Get into the car," said Jerrold, "there, just forward of the driver's
+seat."
+
+With the aid of his lantern Harris picked out the place where he and
+Carl were to stow themselves, and they climbed into the car as directed.
+
+Immediately after that, Jerrold got over the rail and took his seat at
+the levers. It was impossible to see just what he was doing, but the
+clank of a lever came from his vicinity and slowly the front of the
+gas-bag began to point upward.
+
+"Now we're ready," called the inventor.
+
+The popping of a motor began and gradually gathered into a swift murmur.
+
+"And now we're off," added Jerrold. "Stay right where you are and don't
+change your positions unless I tell you."
+
+The whir of the propeller started, and the house and shrubbery began
+slipping away from under those in the car.
+
+"Ach, du lieber!" gasped Carl. "Der eart' vas falling avay from us. I
+vill say my brayers forvarts, packvarts und sidevays, oof it vill helup
+any."
+
+"I've got a bad case of rattles, myself," admitted Harris. "But it's
+for your pard, my boy."
+
+"You bed my life!" returned Carl, "aber I never dit anyt'ing pefore for
+dot bard oof mine dot dook so mooch nerf as vat dis toes. I vill shud
+my eyes, und you dell me, blease, ven ve reach der svamp!"
+
+
+
+
+CHAPTER IX.
+
+ABOARD THE HAWK.
+
+
+Taken at a disadvantage and with two brawny ruffians ranged against
+him, Motor Matt was unable to make any defense. As he lay on the floor,
+head and shoulders still swathed in the window-curtain, one of his
+antagonists held him while the other bound his hands and feet with a
+rope. He was then lifted and carried for some distance. Naturally he
+could have no idea where or in what direction he was being carried.
+
+A few steps were descended and he heard a door softly closed. The cool
+air of outdoors laved his hands--he was sensible of that, although the
+hot stuffiness of the curtain prevented the night air from reaching his
+face.
+
+He was lifted over something, he did not know what, and laid down in
+cramped quarters. A conversation was going on around him, but in tones
+so low he was not able to distinguish the words. He fancied that he
+heard the girl's voice, although his head was so muffled he could not
+be sure.
+
+Presently the unmistakable explosions of a motor came to him.
+
+"Brady is taking me away somewhere in an automobile," he thought, and
+wondered where Carl was that he could not see the machine.
+
+A moment later he felt a gentle, swaying motion as though he was being
+gently swung in a hammock.
+
+Several minutes passed, and then Brady's voice spoke, in a tone so loud
+that Matt was able to hear what he said.
+
+"Take the curtain off his head, Pete, and untie him. It's time he
+took hold here. Keep your revolver handy for use in case he gets
+obstreperous. He's full of ginger and will have to be tamed."
+
+Matt felt some one working at his cords. They were stripped away
+quickly, and the curtain whisked from his head. He jumped up, the floor
+under him swinging with the quick move and almost upsetting him.
+
+"Careful, there!" warned Brady. "Where do you think you are, anyhow?"
+
+Matt was dumfounded. Overhead was the long gas-bag of the Hawk. In
+front of him, at the mechanism of the machine, sat a dusky form which
+he recognized as belonging to Brady. Brady's hands were on the levers.
+
+With a shout of anger Matt jumped toward Brady, the car lurching and
+swaying with his frantic movements.
+
+"Stand where ye are!" came the husky, threatening voice of Pete, from
+behind. "Do as I tell ye, King, or I'll shoot."
+
+Matt turned around. Standing with his back braced against an upright
+timber that held the car to the oval ring under the gas-bag was Brady's
+burly assistant. He held a dark object in his hand and Matt knew it
+must be a revolver.
+
+"Where are you taking me?" demanded Matt.
+
+"Turn around this way," said Brady. "Now that you know what'll happen
+to you if you get too hostile, maybe we can have a bit of a talk
+together."
+
+"Don't shoot!" implored a feminine voice; "I don't want to have any
+shooting, dad!"
+
+The voice came from a bundle on the floor, close to where Pete was
+standing. By looking sharply, Matt was able to see a white, ghost-like
+face hovering against the rail.
+
+The girl had been brought along with them! Matt was glad, for her sake,
+that he had not got into a rough-and-tumble with Brady.
+
+Without seeming to pay the girl more than passing attention, the young
+motorist turned toward the man in the chair.
+
+"Well?" said he, crisply. "What have you got to say about this, Brady?
+I guess you could be arrested for what you've done, all right."
+
+Brady laughed.
+
+"How's a policeman coming up here to get at me?" he asked. "An air-ship
+is a great thing for a fellow who wants to turn a few tricks in spite
+of the law."
+
+"That's your game, is it? Well, what have you to gain by running off
+with me? I told you I didn't have that roll of papers."
+
+"I'm out the blue prints, but I'm in a good motorist. I'll not be able
+to improve the Hawk according to Jerrold's plans, but I guess I've
+got hold of a driver that's good enough to make up for most of the
+improvements."
+
+"If you think I'm going to drive this car for you," said Matt, "you're
+away off in your calculations."
+
+"That's what you think now, but you'll change your tune before long,"
+said Brady, easily. "I know this air-ship pretty well, and I installed
+the motor. All it needed for that was a good machinist and a good
+inventor. I'm not a good driver, though, and I've picked you for the
+job. The offer I made back at the house goes. Five hundred a month.
+Pretty good pay, eh, for a boy of your age?"
+
+"I don't care how much you offer, Brady. As I have already told you,
+no amount of money could hire me to work for you. You're a scoundrel,
+clear through. What you've done to-night proves it.
+
+"Bear a little to the left, Brady!" called Pete, who was evidently on
+the lookout. "You're getting too far to the north."
+
+Brady moved one of the levers, and the ease and certainty with which
+the air-ship swung to the new direction brought Matt's admiration
+uppermost. Never had he been able to resist the lure of untried
+machinery, and here was an experience so novel that it carried him
+out of his troubled environment, so to speak. For a moment, suspended
+in that starlit void and swimming noiselessly through the night, he
+yielded himself to the fascinations of the new experience.
+
+"How powerful a motor have you?" he asked.
+
+"Ten horse-power," answered Brady, "and it weighs forty pounds."
+
+"How do you steer the machine up and down, and right and left?"
+
+"That's where I've got the bulge on Jerrold. One rudder with two
+cross-section planes does all of that. This lever here--I don't know
+whether you can see it or not from where you stand--gives the up and
+down 'dip' to the rudder that makes the machine rise or fall. By moving
+the lever right or left, the air-ship turns in the corresponding
+direction."
+
+"Take me back," ordered Matt, "and land me at the place where you took
+me from."
+
+"You've got a picture of me doing that!" scoffed Brady. "Now that I've
+caught you, I'm going to keep you, see? You're just the sort of a lad I
+need in my business. Grove and Needham, when they finally got back to
+South Chicago with the air-ship, told me all about you. If I'd known
+what I do now at the time you called at the balloon house, I'd have
+taken a different tack."
+
+A muttered imprecation came from Pete. He was thinking of his fall over
+the barrel.
+
+"Those fellows got back without breaking their necks, did they?"
+queried Matt.
+
+"Just about. When they told me what had happened, I sent off that
+telegram."
+
+"We might just as well look this thing square in the face, Brady," said
+Matt. "You've acted the part of a scoundrel in your dealings with me,
+and you haven't gained anything by it. If you don't turn back and put
+me down in South Chicago, I'll make more trouble for you than you can
+well take care of."
+
+"I'll take my chances on that, my bantam. I like your spirit, and we're
+going to get along fine. Just cast in your lot with mine, and I'll
+make a rich man out of you. In the Hawk we can travel all over this
+continent, from Hudson Bay to Patagonia. Where men never went before,
+we can go. No mountain range is so high that we can't cross it, and no
+desert is so barren that we can't wing our way comfortably over it."
+
+Matt stared at the dark figure in the chair. If any honest man had
+talked to him in that way, the young motorist would have been tempted
+to become an aeronaut, for he could see plainly the possibilities of a
+serviceable air-ship; but as for Brady, he was a criminal, and that cut
+him off from any consideration on Matt's part.
+
+The young motorist sank down on his knees and looked over the side
+of the car. They were perhaps a thousand feet in the air. Houses,
+villages, dark expanses of timber and lighter stretches of meadow swept
+past them, moving out from under the car like a dark panorama.
+
+Driving an automobile at speed was like flying, but here was flying
+itself. The new sensation gripped Matt and thrilled him in every nerve.
+
+"How are we heading, Pete?" called Brady.
+
+Pete was leaning over the opposite side of the car, looking forward.
+
+"I'm jest tryin' to git my bearin's, Brady," he answered. "It's so
+pesky dark it's hard to make out jest where we are."
+
+Matt stole a look at Pete's back. The hand gripping the revolver lay on
+the rail. By one quick move Matt could have snatched the weapon. As the
+idea swept through his mind he cautiously changed his position.
+
+Just then a soft hand rested on his and he saw the girl's face pressed
+close.
+
+"Don't do anything desperate!" she whispered, imploringly. "Do whatever
+dad says--it will be better for you. When we get to where we're going,
+I'll help you escape, and----"
+
+"I think, Brady," called Pete, "that ye're still too fur to the north.
+Better shift a leetle more to the left. I won't be sartin, though, that
+I'm right."
+
+"I ought to be there on the lookout," answered Brady. "Come here, King,
+and take the engine."
+
+The girl's words had influenced Matt powerfully. On top of that was the
+alluring prospect of handling a new machine.
+
+"I'll take the engine for a while, Brady," said he, getting up, "but
+you're to remember I'll not hire out to you."
+
+"All I ask is for you to handle the motor," replied Brady. "You'll come
+to your oats quick enough, I'll gamble on that. You watch King, Pete,"
+he added to the other man, "and make sure he sends the Hawk where I
+tell him to. If he tries to send her anywhere else, you know what to
+do."
+
+"That's no josh," answered Pete.
+
+Brady left the chair and went forward. Matt dropped into the vacant
+seat and began studying the various levers with his groping hands.
+
+
+
+
+CHAPTER X.
+
+WILLOUGHBY'S SWAMP.
+
+
+Pete kept his weapon prominently displayed, and through the gloom
+Matt could see the ruffian's arm partly lifted as though ready on the
+instant to bring the firearm into use. This alert attitude on Pete's
+part, however, was more for show than for anything else--at least, Matt
+so regarded it. Brady was not anxious to go to desperate extremes with
+Matt, especially since he wanted him as driver for the air-ship.
+
+Brady, taking up a position where he could peer ahead, was scanning the
+dim landscape sharply.
+
+"Swing her to the left!" he called.
+
+Matt instantly applied the steering lever. Instead of swinging to the
+left, however, the Hawk made a half-turn to the right.
+
+Up came the revolver. With a sharp cry, the girl reached up and caught
+Pete's arm.
+
+"To the _left_, I said!" roared Brady.
+
+"You'll have to give me the chance to learn the machine," answered
+Matt, coolly, as he continued working the lever and brought the Hawk
+around to the proper course. "These levers are new to me. When we steer
+an auto we do it with a wheel."
+
+"I thought ye knowed all about motors," jeered Pete.
+
+"I know something about motors," replied Matt, "but not the first thing
+about air-ships."
+
+As near as Matt could judge, they were proceeding at a speed of
+something like thirty miles an hour. He speeded up the engine a little
+and was surprised at the smoothness with which it worked. The propeller
+hummed in a low, husky drone that was quite different from the song of
+the cylinders.
+
+He moved the steering lever backward a couple of notches. Immediately
+the rudder was tilted and the Hawk began to climb upward.
+
+"Stop that!" yelled Brady. "We're high enough. What are you trying to
+do?"
+
+"Learning the machine," answered Matt, and threw the lever forward.
+
+The front end of the gas-bag tipped downward, and the air-ship slid
+toward the earth with a suddenness that almost threw Brady over the
+rail.
+
+"That'll do you!" he whooped. "Get her on a level again, and be quick
+about it. You can handle the machine, all right, and I don't want you
+to do anything but what you're told."
+
+"All right," said Matt quietly.
+
+For five minutes longer they continued to swim onward through the air.
+A long string of lights shot across the gloomy landscape below them,
+and a whistle came upward from the earth with startling distinctness.
+
+"There goes a train, whistlin' fer Lake Station," remarked Pete.
+
+"We'll be over the town in a minute," said Brady, "and then it won't be
+long until we get to the swamp."
+
+"What swamp?" asked Matt.
+
+"Never ye mind," was Pete's surly rejoinder. "Ye're here to obey orders
+an' not ask any fool questions."
+
+"I don't think it very foolish for a fellow to ask where he's being
+taken."
+
+"Mebby not, but ye ain't findin' anythin' out, see?"
+
+Matt had been doing a good deal of guessing about Carl. What would his
+chum do? What was he doing then? He felt pretty sure that Carl would
+get into the house and go through it from cellar to roof.
+
+But Matt knew that Carl had a good sensible head in cases of emergency.
+Now and again the Dutch boy's temper was apt to make trouble with his
+reasoning, but in the long run Carl could always be counted on to do
+the right thing.
+
+So Matt was not worrying very much about his chum. Carl would take good
+care of the blue prints and ultimately they would find their rightful
+owner.
+
+"Ha!" exclaimed Brady, suddenly, "there's the signal! I'll go back and
+take charge of the motor while we make the landing, Pete, and you take
+the lookout."
+
+Matt gave place to Brady and then stood at the rail, watching
+developments curiously.
+
+Below the air-ship was a great splotch of black shadow, stretching away
+on all sides as far as the eye could reach. Evidently this was the
+swamp. The Hawk was sailing across the swamp toward a big fire that
+glowed in the distance.
+
+With Brady steering and Pete directing, the Hawk approached closer and
+closer to the fire.
+
+"Drop 'er, Brady!" Pete presently called; "we're close on the island."
+
+The nose of the air-ship ducked downward and, for perhaps twenty
+seconds, she raced earthward; then Brady diminished the speed of their
+descent by slow degrees.
+
+Matt, braced on the sloping floor of the car, watched the fire
+apparently come up toward them. A little later he was able to make out
+three human figures against the firelit background below, and a bare
+little plateau took vague form under his eyes.
+
+He watched the landing keenly, and noted how Brady suddenly shifted
+the steering rudder so as to bring the Hawk on an even keel, the lower
+supports of the car just grazing the ground.
+
+The three figures by the fire ran close.
+
+"How's everything, Brady?" cried a voice.
+
+"Finer than silk," called back Brady. "Stand by to catch the ropes, you
+fellows."
+
+The murmur of the motor ceased, the revolving propeller came to a stop,
+and Pete flung out two ropes, one on each side of the car.
+
+The ropes were caught by the men on the ground, a bight of each was
+thrown around a stout stake driven into the earth at an angle, and the
+air-ship was drawn down and safely moored.
+
+Matt was now able to understand why Brady had taken his place as driver
+for the landing. Not only was the method of making a landing new to
+Matt, but there was also danger, unless one was familiar with the
+place, of scraping the trees that covered the swamp and hemmed in the
+cleared space called the "island."
+
+Matt started to spring over the rail of the car.
+
+"Stop, King!" cried Brady. "You don't want to make a bolt for the
+timber and get mired in the swamp, do you? Just remember you're still
+under orders. Take him to the roost, Needham, you and Whipple. Better
+tie him up until he gets used to the place and to our society. He's a
+bit strange, here, and none too willing to stay."
+
+"Did you bring the loot, Brady?" called one of the men.
+
+"Sure! This is moving-day with us and you didn't think I was going to
+leave all that stuff on Hoyne Street, did you? Get out of the car,
+King," he went on, to Matt. "Whipple and Needham will take care of you."
+
+Two of the three men had stepped to the side of the car. In the light
+of the fire, which was blazing at a safe distance from the air-ship,
+Matt discovered that Needham and Grove had been the two aeronauts who
+had had such hard luck with the Hawk during the preceding day.
+
+Needham, who, with Whipple, was facing Matt and waiting for him to get
+over the air-ship's rail, gave a husky laugh.
+
+"We got out of that scrape, all right," said he, "even if we did lose
+our drag-rope."
+
+"And you got me into another scrape," said Matt. "You fellows will pay
+for this!"
+
+"Chirp low, young feller," warned Whipple, catching him by the arm as
+he gained the ground; "your cue is to make friends with us an' not
+bluster about what ye're goin' ter do. There's five husky men here, an'
+we're all surrounded by a swamp that would mire ye up ter the eyes if
+ye tried ter git through it. Oh, I reckon ye won't git away ter make
+any of us pay fer anythin'! This way, an' step lively."
+
+With Needham and Whipple on each side of him and hanging to an arm,
+Matt was led across the open space, past the fire, and to the door
+of a small, roughly built shanty. A little way off there was another
+building, fully as small but apparently somewhat better built.
+
+"This here's the roost," announced Whipple, "an' it's where ye're ter
+pass the rest o' the night. Come in, an' come peaceable."
+
+It was part of Matt's plan, hastily formed on the air-ship just after
+the girl had spoken to him, to accept passively whatever came his
+way--at least for a time. The girl had said that she would help him
+escape, and there was that about her which had awakened his confidence.
+Not only that, but there was also something in the girl's face that
+had aroused his sympathy. She had a history, he was sure, and one that
+was far from pleasant.
+
+There were five cots in the "roost," and Matt was told to lie down on
+one of them.
+
+"Harper used to sleep there," remarked Needham, as Matt stretched
+himself out on the hard bed, "and the deuce only knows where poor old
+Harper is now. You're taking his place, King, and so it's only right
+you should have his cot."
+
+It was on Matt's tongue to say that Needham had another guess coming,
+but he held his peace. He would not show too much of the hostile side
+of his feelings until he had had a chance to talk with the girl.
+
+"What's the use of tying me," expostulated Matt, as ropes were being
+put in place around his wrists and ankles, "if it's impossible for me
+to get away?"
+
+"Orders," answered Whipple, curtly.
+
+After Matt was made secure, Whipple and Needham went out of the
+hut. The young motorist had had a trying day, and even his exciting
+situation was powerless to keep the sleep from his eyes. He dozed off,
+while his thoughts were trying to straighten out the queer tangle
+in which events had bound him. He roused up for a moment when Pete,
+Whipple, Needham and Grove came into the hut and dropped down on their
+cots, but almost immediately he went to sleep again.
+
+It seemed as though he had hardly closed his eyes the second time
+before he was awakened by a light hand pressed upon his forehead. The
+other cots in the room were empty, it was morning, and the girl was
+standing beside him.
+
+"I have brought your breakfast," said she, in a low voice. "We can talk
+a little, but will have to be quick. Dad, or some of the men, may come
+in here at any second! There's a lot that you've got to know, and----"
+
+She was interrupted by the sharp explosion of a firearm outside.
+Stifling a cry, she whirled from the cot and ran to the open door.
+
+
+
+
+CHAPTER XI.
+
+A FOE IN THE AIR.
+
+
+"What is it?" asked Matt, struggling up on the cot.
+
+No revolver had caused the report he had heard. From the sound he knew
+that a rifle had been fired.
+
+A babel of excited voices now came to him from without, accompanied by
+sounds of running feet diminishing rapidly in the distance. Then came
+another report, and another, both from a more distant point than the
+first.
+
+The girl stepped through the doorway and was looking upward.
+
+"Take off these ropes!" called Matt. "Let me get out there and see what
+is going on!"
+
+The girl turned and reentered the hut. Her face wore an expression of
+the utmost concern.
+
+"No," said she, "I can't release you just now. If dad was to come and
+find that I'd set you free, he would suspect me at once and that would
+spoil my plans."
+
+"But what was the cause of that shooting?" persisted Matt.
+
+"There's another air-ship over the island----"
+
+"Another air-ship?" echoed Matt.
+
+"Yes. It must be Jerrold's, although how he ever found out where dad
+was is more than I know. Dad and the rest were shooting at the air-ship
+with rifles."
+
+"I'll bet it's somebody who's come looking for me!" exclaimed Matt. "If
+your father and his gang should kill anybody----"
+
+"They won't," interrupted the girl, confidently; "dad knows better than
+to do anything of that kind. They'll try to put a bullet or two into
+the gas-bag of the air-ship and frighten Jerrold away."
+
+"Go and take another look," said Matt, anxiously. "See what they're
+doing."
+
+The girl glided to the doorway again.
+
+"The other air-ship is moving off," the girl reported, with a measure
+of relief in her voice, as she came back. "I think the bullets must
+have injured the propeller, or some of the machinery, for the air-ship
+is moving very slowly and seems to be in trouble."
+
+"Did you see how many were aboard?"
+
+"There were three in the car--one of them was Jerrold, and he was
+managing the motor."
+
+"The other two," asked Matt, eagerly, "do you know who they were?"
+
+"One of them was in uniform, and looked like a policeman. The other was
+short and thick-set and looked like a German."
+
+"Carl!" exclaimed Matt, jubilantly. "Good old Carl! How did he ever
+find out where I was, I wonder?"
+
+"I'll bet dad is trying to guess the same thing," said the girl. "He'll
+be badly cut up over this. But it's no more than he ought to expect,"
+she added. "Whenever a man breaks the law he'll have to pay for it,
+sooner or later."
+
+"What has your father been doing?" asked Matt.
+
+"I came to talk with you about that. While I'm giving you your
+breakfast, I'll tell you my plans. Dad, and all the rest except
+Whipple, are off in the swamp, somewhere, keeping track of Jerrold's
+air-ship, and that will give us a chance."
+
+Matt swung his bound feet over the edge of the cot, and while he sat
+there the girl drew a chair close and began giving him his breakfast.
+
+"Dad has been doing a lot of criminal things," said the girl, "and all
+he built that air-ship for was to make it easy for him to rob people
+and get away without being found out. Didn't you guess that when I
+showed you that article in the paper? I thought you might."
+
+"I've been mighty thick-headed," answered Matt, between mouthfuls, "and
+I never thought the thing through that far. Possibly it's because so
+much has been happening to me since I went into that place on Hoyne
+Street."
+
+"It's nearly broken my heart having dad act like he's been doing," said
+the girl, her lips quivering. "If mother had lived she'd have kept dad
+straight, but when she died dad just seemed to go to the dogs. He has
+tried to make the people in South Chicago think he was just an honest
+inventor, but, even at that, he stole all his ideas from Jerrold. That
+balloon house, that he built out of some of the proceeds of his first
+robbery, was put up for what they call a 'blind.' With a big house like
+that, out in plain sight, dad felt that everybody would think his work
+was open and aboveboard. When he committed any robberies, the Hawk
+was taken from the shed in the dead of night, and Harper would steer
+it for the place they were to rob. The blackest kind of a night was
+always selected, and only flat-topped buildings were robbed. You see,
+the air-ship would alight on the roof, and dad and the rest would break
+into the building from the top. When they left they always went in the
+same way they came, and the police were puzzled because they could not
+find any clues in the lower part of the buildings."
+
+"It was a slick scheme," commented Matt.
+
+"That's the way Hartz & Greer's place was robbed," proceeded the girl.
+"Dad and the rest got fifteen thousand dollars' worth of goods from
+Hartz & Greer, and for more than a week the stuff has been hidden in
+that house on Hoyne Street. But now dad has left South Chicago for
+good and all. He's afraid the police are beginning to suspect him, and
+that Jerrold might try to do something on account of those stolen blue
+prints."
+
+It was perfectly plain to Matt that the girl's recital of these crimes,
+in which her father had played the leading part, was anything but easy
+for her. She was talking from a sense of duty, and Matt honored and
+admired her for the stand she was taking.
+
+"It doesn't seem possible," said he, gently, "that Brady is your
+father."
+
+"But he is," she answered brokenly, "and he has brought shame and
+disgrace on me. But what could I do? Dad knows how I feel about his
+actions, and he has watched me and kept me away from other people ever
+since he began his stealing. When you came to the house, last night, it
+was the first chance I have had to tell what I know. I overheard dad
+and Pete planning what they were going to do if you came, and--and I
+hoped you would come, although I knew you would never leave the house
+until you were taken away as dad's prisoner. I felt sure, though, that
+I could help you to escape, and I feel even more sure of that now than
+I did before."
+
+"What is your name?" asked Matt, his eyes full on the girl's face.
+
+"Helen," she answered.
+
+"What are your plans, Helen?" he asked.
+
+"My plan," she went on, "is for you to get away from the swamp in the
+Hawk, and to take the stuff stolen from Hartz & Greer with you. That
+will stop everything, for dad will be perfectly helpless without the
+air-ship. Then, too, you can return the stolen diamonds and jewelry to
+Hartz & Greer, and that will go far toward righting one wrong. When you
+are back in South Chicago, you can send the police here and--and they
+can capture dad and the rest."
+
+Matt had finished eating and the girl had put aside the dishes.
+Suddenly she broke down and hid her face in her apron. For a few
+moments she sobbed convulsively.
+
+Small wonder her feelings overcame her! In carrying out her ideas of
+right and justice, she had planned to give her own father into the
+hands of the law.
+
+"You're a noble girl, Helen!" declared Matt. "But how am I to get away
+in the air-ship and to take the stolen property with me?"
+
+"You already know how to run the machine," said the girl, recovering
+herself a little and looking up, "and when the right time arrives I
+will come here and take off your ropes. As for the stolen property, I
+will see to it that that is put in the car before you start. There will
+be danger in what you do, but, from what I have heard, you know how to
+win out in spite of it."
+
+"I will run any risk to get away from here," returned Matt, gravely,
+"but when I go you must go with me. This is no place for you--with such
+a thieving gang!"
+
+"I must stay here," the girl said resolutely. "Even though I am sending
+my father to prison I want to be with him to the last. If something
+isn't done," she continued passionately, "he will go on and on,
+constantly from bad to worse, and perhaps some time"--her face blanched
+as she spoke--"he might receive worse than a prison sentence. It is the
+only way to save him."
+
+It was clear that Helen Brady had spent much time in thinking out and
+planning her present course, and how much mental anguish and bitterness
+of spirit her conclusion had cost her, only she could know.
+
+"I am ready to do whatever you want me to," said Matt, "and if you
+think it best to stay here, all right. I still believe, though, you
+ought to leave this place with me."
+
+"No, no," she replied firmly. "I have thought it all out a dozen times,
+and I have made up my mind as to what it is right for me to do. You
+must get away from here in the air-ship. With the Hawk taken away from
+him, dad will be helpless."
+
+"Haven't you any friends or relatives to whom you could go?" asked Matt.
+
+"I have relatives on my mother's side, but they won't have anything to
+do with dad or me--simply because dad is what he is. They have asked me
+to leave dad and come to them, but I know my place and what it is right
+for me to do."
+
+A brief silence fell between the two, during which Matt turned the
+queer problem over in his mind.
+
+"When do you think your plan can be carried out?" he asked presently.
+
+"It has got to be soon, if at all," she answered. "I don't know what
+effect this appearance of Jerrold's air-ship over the swamp will have
+on dad, but I hope it won't interfere with my plans. We'll have to wait
+a little while and see. Whipple is watching the Hawk now, and----"
+
+Just at that moment a heavy step was heard outside. A man appeared in
+the doorway, stared in at Matt and the girl for an instant, and then
+strode into the hut.
+
+The man was Brady, and his face was black as a thundercloud.
+
+"What're you doing here so long?" he cried angrily to the girl. "Clear
+out! I've got something I want to talk over with King."
+
+With a supplicating look at her father, the girl got up and passed out
+of the hut.
+
+
+
+
+CHAPTER XII.
+
+BRADY CHANGES HIS PLANS.
+
+
+"You've played the devil with me, and no mistake!" scowled Brady,
+whirling on Matt the moment the girl was gone.
+
+"I don't see how you make that out," said Matt. "You're the one that's
+made all the trouble, Brady."
+
+Brady's little eyes glittered as they rested on Matt. For a few moments
+he paced angrily back and forth across the hut.
+
+"How in thunder," he cried suddenly, "did Jerrold ever manage to get a
+line on me? He was over the swamp, a short time ago, with his air-ship,
+and he'd have landed here if we hadn't driven him off. Jerrold knows
+where I am, and he has the means of getting to the island. We've
+crippled his craft, though, and he's had to haul off for repairs. While
+he's gone, I've got to change my plans, somehow, and be ready for him
+when he comes back. That Dutch kid who was with you at the balloon
+house yesterday was in the car of the air-ship, and there was also a
+policeman along. How did that come?"
+
+"You know as much about it as I do, Brady," replied Matt. "I
+disappeared from that Hoyne Street house, last night, and I suppose my
+chum has been getting clues about me and following them up. That's the
+kind of a lad he is."
+
+"Where did he get any clues that would bring him out here?"
+
+"Give it up."
+
+Brady took a few more turns across the room, presently halting in front
+of Matt.
+
+"You didn't bring that roll of blue prints to Hoyne Street, last
+night," said he. "Where did you leave it?"
+
+"Left it out in front of the house," grinned Matt.
+
+Brady started.
+
+"In front of the house?" he echoed.
+
+"Yes."
+
+"Cached?"
+
+"Certainly."
+
+"Under the sidewalk?"
+
+"No; in the pocket of my Dutch pard."
+
+Brady stared incredulously. Then he swore.
+
+"That Dutchman was out in front all the while you were in the house?"
+
+Matt nodded.
+
+"He came with me from Chicago. I got to thinking there might be a trap
+in the house, and that some one was there who wanted the blue prints,
+so I made up my mind that it would be a wise move to leave Carl out in
+front, and to let him keep the roll."
+
+"That chum of yours must have seen the Hawk when she climbed out of the
+back yard," growled Brady, "but how in the fiend's name was he able to
+get Jerrold and the Eagle and follow us? It was dark, and we had a long
+start of them."
+
+"One guess is as good as another," said Matt, calmly. "I told you you'd
+get yourself into trouble if you tried to make a prisoner of me. The
+best thing you can do now is to send me back to South Chicago in the
+air-ship."
+
+"Think I'm a fool?" snarled Brady. "It may be that you're all that
+stands between me and my men and capture. I'll hang onto you, King,
+and I'll let that Dutch pard of yours know that if Jerrold don't keep
+away from this swamp with his air-ship you're going to connect with
+your finish. It's neck or nothing with me, now, and I'll go any length
+to keep myself out of the 'pen.' I've laid out a fine campaign for the
+Hawk, and I don't intend to have all my plans nipped in the bud, right
+at the start-off."
+
+"I suppose," said Matt, scathingly, "that your campaign is one of
+robbery, and that you're going to make a pirate ship out of the Hawk?"
+
+"That's where you put your finger on the right button!" declared Brady.
+"I'm going to be a freebooter, and take my toll wherever I can find
+it. It's easy to swoop down on a lot of spoil, pick it up and make off
+with it. And what can the law do?" He laughed mockingly. "Policemen
+will have to have wings to get anywhere near me."
+
+"And that's what you wanted me for, is it?" cried Matt, indignantly;
+"to drive the Hawk around through the air and help out your villainous
+plans! I would let you kill me first."
+
+"Rot! I'm going to stick to my original intentions, but there's got to
+be something of a change in my immediate plans. We've all got to pull
+out of here and to take what plunder we've got cached in the swamp.
+The Hawk will have to make three or four trips, and they must be made
+before Jerrold and his air-ship can interfere with us. If Jerrold fixes
+up his air-ship and comes back, we'll just tell him what will happen to
+you if he lingers in the vicinity of the swamp. I'm banking on that to
+send him packing again, and to keep him out of sight until I can make
+a change of base. You'll go away on the Hawk's first trip, and it will
+probably be only half an hour before you can start."
+
+Brady started for the door, but halted before he reached it and faced
+around.
+
+"Either one of two things happened to put that Dutchman and Jerrold on
+my track," said he. "Either Harper has been caught, and has told what
+he knows, or else a letter I gave Needham to deliver to Whipple, here
+in the swamp, has fallen into the hands of the police. It don't make
+much difference, though, how Jerrold got next to our hang-out. The
+main thing is that he knows where we are, and that you will be put in
+a mighty tight corner if he keeps on trying to make trouble for me.
+That's about all, King. I want you to understand what you're up against
+and be ready for whatever happens. I'm not going to have my plans
+knocked galley-west just as I'm on the point of launching them."
+
+With another black scowl, expressive of his savage determination,
+Hector Brady strode out of the hut.
+
+Matt was beginning to understand why Helen preferred to see her father
+in prison rather than free to carry out his campaign of lawlessness.
+Possessing a practical air-ship like the Hawk, Brady could commit
+untold depredations and snap his fingers in open defiance of the law.
+
+The young motorist shuddered to think of the scoundrel's comprehensive
+plans, and of the part he had intended to make his prisoner play in
+them.
+
+Helen's reasoning was logical, and the expedient she had suggested was
+as simple as it was effective. By taking the Hawk away from Brady she
+would make it impossible for him to follow out his nefarious schemes.
+The beautiful simplicity of the countercheck aroused Matt's admiration.
+
+But how was the countercheck to be brought about? The appearance of
+Jerrold's air-ship over the swamp had made doubly difficult the work
+the girl was counting upon having done. Not only that, but the coming
+of the Eagle had increased Matt's peril. There was no doubt in the
+young motorist's mind but that Brady would go to any extreme in order
+to keep himself and his companions from being captured.
+
+All these different aspects of the situation floated through Motor
+Matt's mind swiftly. Two or three minutes after Brady had left the hut,
+and while Matt was still considering the problem that confronted the
+girl, Helen herself stole in through the door.
+
+Her face was haggard, but her eyes were bright and full of resolution.
+
+"You shouldn't be here," protested Matt. "Your father suspected
+something when he found you with me a little while ago and ordered you
+away. What if he should come back and see you here again?"
+
+"I don't think he'll come back, but I've got to take the risk, even if
+he does." The girl spoke quickly and steadily and made her way swiftly
+to Matt's side. "Dad has changed his plans--I was listening to all he
+said, out there at the back of the hut. He's going to use the Hawk to
+take us all away from the swamp, and _you're going to go on the Hawk's
+first trip_! That means that we must do what we can, at once. If we
+fail now, everything is lost."
+
+She was breathlessly eager, but her calmness at such a moment surprised
+Matt. Lifting her hands she took a small poniard from the bosom of her
+dress, bent down and severed the cords that secured Matt's hands. Then,
+with one downward stroke of the keen blade, she freed his feet.
+
+"Where are your father and the rest of the men?" asked Matt.
+
+Before she answered, Helen glided to the door and took a cautious look
+outside.
+
+"Some of the stolen goods have been hidden among the bushes of the
+swamp," said she, returning to Matt. "You are to be sent away with the
+loot, on the first trip, and dad himself will have to take you. He,
+and everybody except Whipple, have gone to the swamp. Whipple has a
+rifle and is guarding the Hawk. Whatever we do, Matt, we've got to do
+in a hurry. The bag of goods taken from Hartz & Greer is behind this
+hut," she pointed to an unglazed opening in the rear wall as she spoke.
+"While the rest are in the swamp, I will go to the Hawk and talk with
+Whipple, getting around on the other side of him so that his back will
+be in this direction. While I am holding his attention, you will creep
+up on him from behind and, between us, we will try and get the rifle.
+It's a desperate chance, but we will do the best we can."
+
+"You're a brave girl, Helen!" declared Matt.
+
+"I'm doing what I think is right, and that always helps a person's
+courage. I'm more worried about you than I am about myself. If anything
+should go wrong--if anything should happen to you because of the help
+you are giving me----"
+
+For the first time her voice faltered. Matt reached out and caught her
+hand reassuringly.
+
+"Don't fret about me," said he. "There won't be any trouble about my
+getting the best of Whipple, with you to help. Is the Hawk all ready
+for a flight? I mean is there plenty of gasoline in the tank, and
+plenty of oil?"
+
+"Yes, dad has seen to that. So far as the air-ship is concerned, it
+is ready to carry you quickly and safely out of the swamp. Now I will
+steal out of the hut and talk with Whipple."
+
+Once more she started for the door. Hardly had she reached it, however,
+when she drew back with a gasp of consternation. Turning, she beckoned
+to Matt.
+
+"Too late!" she whispered, her voice sharp with anguish and
+disappointment. "Oh, why have they come just at this time!"
+
+Matt glided quickly to her side and peered out through the half-opened
+door.
+
+What he saw was well calculated to discourage him and the girl.
+
+
+
+
+CHAPTER XIII.
+
+INTO THE SWAMP.
+
+
+Needham, Pete, Grove and Brady had not been long carrying out their
+work of recovering the cached goods. They were returning from the edge
+of the bushy timber, ascending the slight elevation of the "island" on
+their way to the Hawk, each bearing an armful of plunder.
+
+In his stealings, Brady had not bothered with bulky articles but had
+confined himself to "lifting" smaller and richer loot. The stuff was
+all in small sacks.
+
+As the men walked past the "roost" on their course to the air-ship,
+Matt and the girl withdrew from the door to avoid being seen. Through a
+crack in the wall, however, they were able to keep close track of what
+went on.
+
+On reaching the Hawk, the bundles were deposited on the ground.
+Whipple, leaning on his rifle, stood watching while the bags were
+heaped up at the side of the air-ship.
+
+For a few moments the villainous crew had their heads together in close
+and earnest conversation. Now and again their eyes were lifted aloft,
+evidently on the alert for some sign of the Eagle. Brady, it could
+be seen, did most of the talking. Suddenly, after a sharp scrutiny
+overhead, Brady whirled around and started for the hut.
+
+"He's coming after you!" half sobbed the girl.
+
+"What's the reason I can't escape through that window in the rear
+wall," asked Matt, hurriedly, "and take refuge in the swamp?"
+
+The idea seemed to electrify the girl.
+
+"I hadn't thought of that," she whispered, catching his arm and
+starting for the window. "The back of the hut is close to the trees and
+bushes on this side of the island, and I know something about the reefs
+of dry ground running through the swamp in the vicinity of this place.
+Come!" she added; "we must hurry."
+
+Her despair had vanished in a flash, and her steadiness and resolution
+had all come back. She climbed through the window and, as Matt
+followed, she was picking up a small bag that had stood close to the
+rear wall.
+
+Without speaking, and once more clasping his arm, she hurried him into
+the tangled bushes that came up to within a few feet of the hut. There,
+screened by a dense thicket, they paused to note further developments.
+
+Their position, of course, rendered it impossible for them to see the
+front of the hut, but they were so close they could hear Brady's oath
+of astonishment and alarm when he discovered that Matt was missing.
+
+The next moment Brady could be seen rushing around the side of the hut
+and a little way in the direction of the group standing beside the Hawk.
+
+"He's gone!" roared Brady. "The cub's got loose and skipped!"
+
+The rest were roused into frantic activity.
+
+"I'll sw'ar he didn't git out while I was watchin' the Hawk," cried
+Whipple. "Anyways, he can't be fur off."
+
+"Hustle around!" fumed Brady. "Get into the swamp, every man-jack of
+you, and find that whelp wherever he is. I wouldn't have him get clear
+for a thousand, cold!" All the gang forthwith became exceedingly busy.
+They darted off in various directions, and Brady himself, accompanied
+by Grove, started for the side of the island from which Matt and the
+girl were watching.
+
+"We'll have to get away from here!" breathed the girl, turning. "Follow
+me, Matt, and be careful where you step. If you're not careful, you may
+find yourself mired in the swamp."
+
+"Trust me for that," answered Matt. "I'll carry this," he added, taking
+the bag from the girl's hands.
+
+The swamp, into which they were now headed, presented a matted tangle
+of undergrowth growing among the trees. Through the bushes could be
+seen a glimmer of stagnant water, and the whole place seemed as dank
+and loathsome as a tropical jungle.
+
+The girl picked her way carefully, parting the bushes ahead of her and
+stepping from hummock to hummock. Finally they reached a little bare
+uplift of dry earth, and halted to listen. They could hear nothing of
+pursuit, and the girl drew a long breath of relief.
+
+"Dad don't know that I've explored this swamp," said she. "I have lived
+on the island for nearly six months--dad used to keep me here while he
+was doing his thieving in South Chicago, so I wouldn't be able to tell
+what I know and give him away, I guess."
+
+She sank down on the flat piece of turf for a few moments' rest. The
+ground, although dry, shivered under them as they moved, and seemed
+every moment as though about to give way beneath their weight and let
+them down into the morass.
+
+"This is a treacherous-looking place," remarked Matt, peering off into
+the trees and bushes that hemmed them in on every side.
+
+"It's all of that," replied the girl.
+
+"It would be easy for a person to get lost."
+
+"Not easy for me, as I know it too well."
+
+"If I can get away in the Hawk," went on Matt, after a brief silence,
+"this will make it necessary for you to go with me."
+
+"Why?" she queried, lifting her wide, dark eyes to his.
+
+"Can't you understand? Your father and his men will discover that you
+are not on the island, and they will suspect that you helped me out of
+the hut. What will your father do when he finds that out?"
+
+A shiver swept through the girl's slight form.
+
+"I suppose he will half kill me," she answered. "But I shall stay with
+him. I am his daughter, and it's my duty to be with him to the end."
+
+"You mustn't be foolish," said Matt, inclined to get out of patience.
+"You're carrying your idea of duty to your father altogether too far."
+
+"I've thought it all out," she answered firmly, "and my mind is made
+up. Please don't try to argue with me. It may not be possible for you
+to get away in the air-ship now," she added, with a sigh of regret.
+"If you can't, I will try and get you through the swamp. I don't know
+anything about it, though, after we get a little away from the island."
+
+"Then," proceeded Matt, not giving up his argument that Helen Brady
+should go away with him, "your father will be madder than ever when he
+finds out you have taken the goods stolen from Hartz & Greer."
+
+"That's what I expect, but it's right that the stuff should be
+returned. A person ought to have principles, Matt, and I don't think a
+person amounts to much if he or she can't stand a little suffering on
+account of their principles."
+
+"That's right, too," muttered Matt.
+
+"There's fifteen thousand dollars' worth of diamonds and jewelry in
+that bag," Helen went on, "and Hartz & Greer have offered a reward of
+twenty-five hundred to any one who will return the property."
+
+"That money will go to you," said Matt, promptly. "It's right that it
+should. Look at the risks you're taking to have it put into the hands
+of its rightful owners again! Some time, Helen, you will be rid of your
+father, and then the money will come handy."
+
+She was gazing at him steadily, and there was something of rebuke in
+her eyes.
+
+"You don't mean that, Matt," said she, quietly.
+
+"Why not?" he demanded.
+
+"Would it be right for me to take a reward for returning property my
+own father had stolen?"
+
+Matt was amazed by the simple directness of the girl's reasoning.
+And she was right, entirely right. Nevertheless it took one of fine
+character to reason and to act as the girl was doing.
+
+"If you succeed in getting away with the bag," Helen continued, "I want
+you to give it back to the rightful owners. Tell them it comes from
+Hector Brady's daughter, and that she hopes they will not be too hard
+on her father."
+
+"You bet I'll tell them," said Matt. "What's more, I'll get through
+this swamp on foot, if I have to, and I'll consider it a mighty fine
+thing to lug the bag along and turn it over to Hartz & Greer."
+
+"I felt sure you'd help me," murmured the girl. "There was something in
+your face that told me you could be depended on the moment I looked at
+you at the door of that Hoyne Street house."
+
+"Then the impression was mutual," said Matt. "If I hadn't read honesty
+in your face, along with a desire to help me, I'd have made a rush out
+of that room in the Hoyne Street place the moment I read your warning
+on the fly leaf of the book."
+
+"It was well you didn't do that. You'd have been caught. Pete was
+behind the window curtain all the time. That was why I had to write
+what I wanted you to know, and call your attention to it indirectly. If
+you had----"
+
+The girl was interrupted by a distant rustle of bushes. Stifling the
+words on her lips, she sprang erect.
+
+"Dad's coming this way," she whispered. "I don't think he has the least
+idea where we've gone, but he seems to be blundering in the right
+direction. We'll have to hurry on."
+
+Once more they resumed their flight, Matt carrying the bag and
+carefully following in his companion's footsteps.
+
+The way became increasingly difficult, and the bushes even denser than
+they had been at the point where they had entered the swamp. Then, too,
+the hummocks which offered them foothold became farther apart so that
+it was necessary to leap almost blindly through the brush in getting
+from one to another.
+
+Occasionally they halted and listened, but were unable to hear any
+sound behind them to indicate that Brady and Grove were still on the
+right track.
+
+Just as Matt was congratulating himself that they had again eluded
+their pursuers, a cry from the girl, muffled but full of distress,
+reached him.
+
+Between him and her a screen of bushes intervened, and the cry had come
+a moment after she had taken a headlong plunge through the leafy tangle.
+
+Not knowing what could have happened, and fearing the worst, Matt
+shifted the bag to his other arm, drew his leather cap well down over
+his forehead so that the visor would protect his eyes, and leaped
+boldly after the girl.
+
+By good luck, rather than by any calculation on his part, he landed on
+a shaking hummock, and found that Helen had plunged into the watery
+morass.
+
+Dropping the bag, he reached down, grasped her about the waist and
+dragged her from the clutching grip of the swamp.
+
+"We'll have to go back," were the girl's first words, as he held her on
+the narrow foothold.
+
+"Why?" he asked.
+
+She waved her hand in the direction toward which they were going.
+
+An open space, clear of trees and bushes, lay before them--a veritable
+quagmire with not a place in all its extent where they could set their
+feet.
+
+They would have to go back! With Brady and Grove on one side of them,
+and this impassable bog on the other, it looked as though they had been
+caught between two fires.
+
+
+
+
+CHAPTER XIV.
+
+A DESPERATE CHANCE.
+
+
+Once more the girl was plunged into despair.
+
+"We'll have to give up," she whispered, tearfully. "We have tried hard,
+but luck is against us. For several minutes we have been traveling over
+ground I know nothing about. When I saw that open stretch of swamp, my
+heart failed me and I fell off the firm ground. You see what a horrible
+place this is, Matt!"
+
+"Isn't there any way to get around to the other side of the island?" he
+asked.
+
+"Yes, we could have done that, but I was trying to take you as far as I
+could toward the other edge of the swamp."
+
+"We'll have to give that up, now, and work our way around the island."
+
+"In going back," faltered the girl, "we may meet dad and Grove!"
+
+"We must take the chance," he answered; "there's nothing else for it."
+
+"And in going around the island," proceeded the girl, dejectedly, "we
+may meet some of the others who are looking for us."
+
+"That's another risk we will have to run. Come on," he continued,
+picking up the bag. "I'll lead the way back."
+
+"You've got a way about you," said Helen, "that gives a person courage."
+
+"A fellow would be a pretty poor stick," returned Matt, "who couldn't
+keep his nerve with a girl like you to help him."
+
+Helen's dress was torn by the bushes, and her hands and face were
+scratched and bleeding; but she seemed to mind her physical discomforts
+very little, so eager was she to have Matt's escape prove successful.
+
+Listening intently for any sounds made by Brady and Grove, Matt and the
+girl started back over the course they had recently covered.
+
+They had not gone far when the sounds they feared came to them. As they
+stood together and listened, they could hear Brady and Grove talking
+back and forth. Their voices, and the crashing of the bushes, were
+growing rapidly in volume, and proved that they were coming closer.
+
+The girl began to tremble. Matt pressed her hand reassuringly. Off to
+the right of the course they had been following his quick eye detected
+a foothold among the matted bushes. He pointed it out to his companion.
+
+"Get there, quick!" he whispered.
+
+She leaped for the spot at once, and he was not slow in following her.
+Then, crouching down, they peered through the thicket.
+
+Brady came jumping into sight, clutching a revolver in his hand.
+
+"I'm positive I heard something ahead, Grove!" he cried.
+
+"It must be King, then," answered Grove, floundering along in the rear.
+"He's been makin' a better hike of it through this blasted swamp than I
+ever thought he could."
+
+"There's an open stretch farther along," went on Brady, grimly.
+"That'll stop him, and we'll have him in a few minutes."
+
+Brady leaped out of sight, and Grove likewise jumped past and vanished.
+
+The girl had scarcely breathed while the two men were so close to them.
+
+"Now we've got a chance," whispered Matt. "While they're going on
+toward that open part of the swamp, we'll get back toward the island
+and double around it."
+
+"We won't have to go far, now," rejoined the girl, her hopes rising,
+"before we can turn to the right and start around the island."
+
+Matt continued to lead the way back, making the best time he possibly
+could. When the girl called softly to him, he stopped.
+
+"Here's where we turn," said she. "I'd better go ahead from now on."
+
+He waited for her to gain his side, then followed as she continued to
+make her way onward through the bewildering tangle. Time and again
+Matt, if alone, would have lost his bearings, but Helen, being on
+familiar ground, was never for one moment at a loss.
+
+Their one fear now was that they should encounter some of the others
+who were searching, but they heard nothing to cause them the slightest
+uneasiness.
+
+At last, after half an hour of tiring work, Helen drew to a halt.
+
+"We're about opposite the place where the air-ship is moored," said she.
+
+"That's where we want to be," answered Matt. "Make for the edge of the
+island, Helen, as close to the air-ship as you can get."
+
+Once more the girl started off. The bushes thinned perceptibly as they
+came closer and closer to the solid ground. This rendered the going
+easier, and it also enabled Matt and the girl to make less noise in
+getting through the undergrowth. In nearing the island they redoubled
+their caution, and when they finally reached a spot from which they
+could look out and take in the situation in the vicinity of the "roost"
+and the air-ship, they congratulated themselves on the care they had
+exercised.
+
+They were not more than a dozen feet from the place where the Hawk was
+secured.
+
+Two rifles were leaning against the car, and two of the men--Grove and
+Needham--were sitting on the ground, occasionally looking aloft.
+
+Brady, Whipple and Pete were no where in sight.
+
+"We must have crippled that air-ship of Jerrold's pretty badly,"
+Needham was saying. "If King hadn't made this delay for us, the Hawk
+would have been well away on her first trip."
+
+"That kid is a slippery customer," growled Grove. "The old man is riled
+for fair over the way he's cuttin' up."
+
+"What's the use o' botherin' with him? The thing to do is to cut out o'
+this an' leave King in the swamp."
+
+"I reckon Brady'd do that, if it wasn't for the bag of loot King seems
+to have taken along with him."
+
+Both men had thrown off their hats, and Grove was nursing a number of
+scratches on his face and hands.
+
+"We had a rough time of it," said he, "an' the old man sent me back
+to find out if any of the rest had had any success. If King had been
+found, I was to fire a signal-shot with one of the rifles."
+
+"Hang the luck, anyhow!" snorted Needham. "It was the worst thing Brady
+ever done when he tangled up with King. The lad has a will of his own,
+an' I knew well enough he'd never take hold an' help us out runnin' the
+motor."
+
+"King has got more backbone than any fellow of his age I ever saw, and
+that's a fact. The girl must have helped him. And that's another place
+where Brady has been lame, all along. He ought to have sent the girl
+away, somewhere. She hasn't got any business hanging out with a gang
+like this."
+
+While Matt had been watching and listening, he had been turning over
+several plans in his mind. Here was a chance, albeit a desperate one,
+for getting hold of the air-ship.
+
+He turned to the girl.
+
+"Helen," he whispered, "I'm going to see if I can't capture the Hawk."
+
+"You can't," she returned, fearfully. "Grove and Needham are armed
+and--and they'll shoot."
+
+"They can't shoot if I get hold of those rifles first," went on Matt,
+still speaking in guarded tones.
+
+"How will you do that?"
+
+"Their backs are toward us. I'll creep as close to the Hawk as I can,
+then, if they hear me, as they probably will, I'll make a rush for the
+guns."
+
+The girl was silent for a moment.
+
+"There's nothing else to be done," she whispered, at last. "Count on
+me, Matt, to do whatever I can to help."
+
+"You keep back, Helen," he counseled. "If I succeed in getting the
+guns, I won't need your help; if I don't, your help would do little
+good. Here I go."
+
+Slowly and cautiously Matt crept out of the bushes. The car of the
+air-ship was between him and the men, and this served to screen him,
+up to a certain point; but the two rifles were leaning against the
+opposite side of the car, and in order to lay hold of them he would
+either have to go around the long framework, or else cross the car. He
+made up his mind to take the latter course.
+
+Without being discovered, he managed to reach the side of the car;
+then, just as he was rising to step over the rail, Needham caught sight
+of him.
+
+With a wild yell Needham gained his feet. The yell brought Grove up
+like a shot. For an instant, the two rascals were paralyzed by the
+unexpected appearance of Matt. Their moment of inaction afforded the
+young motorist just the opportunity he needed.
+
+Flinging himself into the car, and across it, he snatched the rifles
+away from the rail, just as the hands of Grove and Needham were
+outstretched to take them.
+
+One of the weapons he flung behind him.
+
+"Nail him!" cried Grove; "down him, before he gets a chance to shoot!"
+
+Needham, no less than Grove, realized the necessity of capturing Matt.
+Matt, however, had no intention of using the remaining rifle on either
+of the two men; neither did he have it in mind to let them get away, or
+rough-handle him.
+
+As the two rushed forward, Matt flung the rifle to his shoulder, and
+his gray eye sparkled menacingly along the barrel.
+
+"Keep off!" he warned, swaying the muzzle of the gun back and forth
+so as to keep both men under it; "keep away from me and stand right
+where you are! I mean business, right from the drop of the hat, and you
+fellows might as well understand it."
+
+
+
+
+CHAPTER XV.
+
+A DARING ESCAPE.
+
+
+The menace of the steady gray eye and the swaying gun muzzle were
+enough for Grove and Needham.
+
+"Here's a go!" growled Needham, casting a yearning look around him toward
+the timber.
+
+"I'm going to make a 'go' of it, all right," averred Matt, grimly, "no
+two ways about that. What are you doing with your right hand, Needham?"
+
+Needham's hand had wandered toward his hip. Matt was watching both
+scoundrels so sharply that not a move they made escaped him.
+
+Needham brought his hand around in front of him.
+
+"What are you trying to do, King?" queried Grove, evidently seeking
+to gain time and give Brady, Pete or Whipple a chance to come on the
+scene.
+
+"I'm trying to get away from this place," replied Matt, "and I've not
+much time to waste in talk. I guess you know that fully as well as I
+do."
+
+Still keeping the rifle trained on the two men, he climbed out of the
+car to the ground.
+
+"Now," he went on, "I'll tell you fellows what you're to do, and then
+we'll be able to work quicker. You will both get into the car, and get
+in together so that I can cover you more easily with this one gun.
+Needham will then place his back against the upright timber that helps
+suspend the car from the hoop--and mind you take the timber farthest
+from the driver's seat. On the bottom of the car there's a coil of
+small rope. With that, Grove will tie Needham to the upright. Is that
+clear?"
+
+"Why, what the blazes----" began Grove, but Matt cut him short.
+
+"There's no time for talk, I tell you!" he called, sharply. "Brady and
+the other two may show up here, and I'm going to have this work done
+before that happens."
+
+"But----"
+
+"Get into the car!"
+
+Matt's finger flexed ever so slightly upon the trigger of the gun. The
+watchful eyes of Grove and Needham detected the movement and both made
+haste to tumble into the car.
+
+"I'd give a farm to know what you've got up your sleeve," growled
+Needham, as he backed slowly against the upright timber.
+
+"Move more quickly," warned Matt, "or you'll find what I've got in this
+gun. I used to be in Arizona, and I know how they deal with matters of
+this sort down there. They're not in the habit of wasting so many words
+as I'm doing. Pick up that rope, Grove," he added, "and get busy with
+it. Mind you tie hard knots! No fast-and-loose plays at this stage of
+the game."
+
+Grove was a bit languid in his operations, and as he worked he gave
+more attention to the quarters from which Brady, Pete and Whipple might
+be expected than he did to the tying of Needham.
+
+"Grove," called Matt, sternly, "I'm not going to bother much more with
+you! Move faster, and pass some of that rope around Needham's arms. I
+don't want his hands left free. Pull the coils tighter."
+
+After a fashion, Grove got his comrade tied.
+
+"Will that do you?" he demanded, gruffly, turning to glare at Matt.
+
+"That will answer. Now turn your back to Needham's."
+
+"Say, by thunder I'm not going to stand for----"
+
+"_Turn your back!_"
+
+Matt shoved the muzzle of the rifle toward Grove's breast, and the man
+made haste to place himself against the upright piece of the car's
+framework.
+
+It was Matt's intention, then, to drop the rifle and proceed with the
+tying of Grove himself, but the girl suddenly appeared and climbed into
+the car.
+
+"I'll do the rest, Matt," said she, picking up the loose end of the
+rope.
+
+Matt had planned to have the girl remain in the thicket, taking no part
+in his operations; but she had different ideas.
+
+Grove and Needham both glared at the girl.
+
+"The old man will make you sorry for this!" fumed Grove.
+
+"I expect he will," replied the girl. "He has made me sorry for a lot
+of things lately."
+
+Around and around the bodies of the two men Helen coiled the rope.
+Then, when she had come to the end of it, she made it fast with a knot.
+
+Pausing a moment after she had finished, she drew a revolver out of
+Needham's hip-pocket and dropped it on the driver's seat.
+
+"You had better have that in your own hands, Matt," said she, quietly.
+"It will be easier to handle than the rifle."
+
+"Don't get out of the car, Helen," called Matt, as the girl was about
+to climb over the rail. "You can't stay here after this."
+
+"I can and I must."
+
+Her resolve to remain with her father was unshaken; but there was
+a bright light in her eyes which Matt had not seen there before.
+Evidently the success that was attending Matt's plans to get away with
+the air-ship had lifted a grievous load from her spirits.
+
+Walking around the car, Helen picked up the bag which they had taken
+with them into the swamp.
+
+"This must go with you, Matt," she continued, pushing the bag under the
+driver's seat, "along with the rest of the stuff piled up on the ground
+there."
+
+While she was on that side of the car she cast off the mooring-rope and
+flung it into the air-ship.
+
+Matt dropped the rifle and released the rope on the other side.
+
+The Hawk was now in readiness to take to flight. With nothing to hold
+it, the gas-bag began to feel the effects of the wind that was blowing
+and to move about in answer to the faint gusts. But it rode on an even
+keel, for its buoyancy had to be accelerated by the propeller before it
+would rise, or could be maneuvered.
+
+The girl had started toward the bags, heaped up on the ground. Before
+she could reach them, however, a loud yell from the opposite side of
+the island caused her to halt in consternation.
+
+"Dad!" she cried, wildly; "he's coming!"
+
+"Brady! This way, quick!"
+
+The clamoring whoops went up from Needham and Grove as they struggled
+fiercely to free themselves.
+
+Matt, seeing that there was not an instant to be lost, leaped into the
+car and tilted the steering-rudder at an angle which would carry the
+air-ship upward.
+
+"Come along!" he shouted to the girl as he started the engine. "Get
+into the car, Helen!"
+
+"Hurry, hurry!" screamed the girl, running directly away from the car
+and in the direction of Brady and Pete, who were making for the Hawk at
+a run.
+
+A pang of regret ran through Matt at the thought of leaving Helen Brady
+behind to bear the brunt of her father's anger; but there was no time
+for argument. He started the propeller, and the Hawk began to move up
+the airy incline toward the tops of the trees that walled in the edge
+of the "island."
+
+The struggles of Matt's two prisoners became desperately frantic. So
+violently did they wrestle with their bonds that the car tipped and
+swayed dangerously. Matt had no time to give to them, just then, being
+wholly wrapped up in the maneuvering of the Hawk.
+
+He gave the rudder a further tilt, throwing the air-ship to an angle
+that caused Grove's feet to slip from under him, so that only the
+support of the rope and the upright held him to his place.
+
+"Shoot!" he bellowed. "Why don't you blaze away at him, Brady?"
+
+Brady had evidently held his fire, hoping to get the air-ship back
+without injury; and, even now, as his rifle and Pete's began to crack
+murderously, the target of their bullets was Matt.
+
+Two or three of the leaden spheres zipped past Matt's head, missing
+him by the narrowest of margins. Strangely enough, however, Matt was
+more worried about the harm the bullets might do the gas-bag, or the
+machinery, than he was about any damage they might do him.
+
+Faster and faster he speeded up the engine, and the Hawk raced toward
+the clouds. She cleared the tops of the trees, gained the clear sky,
+and, at a height of five hundred feet, was brought to an even keel.
+
+Then, and not till then, did Matt venture a look below. He was just in
+time to catch one fleeting glimpse of those he had left behind on the
+"island." What he saw aroused his anger and indignation.
+
+Helen, still true to her resolve to help Matt, had seized hold of her
+father's rifle and was struggling to keep him from using it. The minute
+figures were strangely clear, and Matt saw Brady lift his fist and
+strike the girl down. Then the tops of the trees interposed and cut off
+the unpleasant sight. Matt faced about, a steely glint in his gray eyes.
+
+"Here's a fine lay out!" Grove was clamoring, far gone with chagrin
+and baffled rage. "One kid, single-handed, captures two of us and runs
+off with the air-ship, right under the noses of Brady and the rest!
+Oh, well, we're entitled to all we get out of this. We don't deserve
+anything better."
+
+"You'll get something more than you expect," said Matt, picking up the
+revolver and pushing it into his pocket, "if you don't stop squirming
+around like that. It's hard to steer when you're rocking the car in
+such a fashion. You fellows are my prisoners, so make the best of it."
+
+"Yes," growled Grove, "and us two aeronauts will have a fine tale to
+tell when you take us where you're going to. You've stolen this car.
+That'll cook your goose for you."
+
+"Brady," answered Matt, "can have his air-ship back whenever he wants
+to show up and claim it."
+
+There followed a brief silence, during which Matt noted that the wind
+was brisk, and from the north, and exulted over the speed the Hawk
+developed in the teeth of it.
+
+Needham was first to break the silence.
+
+"If I had my hat, and was able," said he, craning his head around to
+get a look at Matt, "I'd take it off to you."
+
+The lad in the driver's seat made no response. He was hurrying toward
+South Chicago.
+
+Where was the Eagle? The skies in every direction were clear and the
+other air-ship was nowhere to be seen.
+
+Motor Matt, as he drove the air-ship steadily against the wind, kept
+close watch of the captured aeronauts.
+
+
+
+
+CHAPTER XVI.
+
+THE END OF THE MID-AIR TRAIL.
+
+
+The failure of Carl, Harris and Jerrold to make a landing on the
+"island" has already been recorded.
+
+They had seen the Hawk, moored at one edge of the cleared space,
+and they had seen Brady and the others; but, of course, it had been
+impossible for them to see anything of Matt. The young motorist, at
+that time, was bound hand and foot and lying on the cot in the hut.
+
+With bullets flying around them and threatening injury to the Eagle,
+it was not policy to remain hovering over such a nest of desperate
+scoundrels very long.
+
+"We'll get out of here," cried Harris, angrily, "and come back with men
+and guns enough to give those fellows a taste of their own medicine.
+Don't let any harm come to the air-ship, Jerrold. We're going to need
+her, later."
+
+Just as Harris finished speaking, a bullet slapped into the motor and
+the machinery at once began to go wrong.
+
+"Too late," responded Jerrold grimly; "they've already nipped us."
+
+"Py chimineddy," roared Carl, "I vish I hat somet'ing vat I could shoot
+mit ad dem fillains!"
+
+Limping and staggering, Jerrold managed to urge the Eagle out of harm's
+way.
+
+"She won't drop on us, will she?" asked Harris, looking anxiously
+downward at the tree-tops.
+
+"No," replied Jerrold, "the gas-bag is uninjured, so we can't fall; and
+the motor is working, too, after a fashion, and that enables us to make
+a slow rate of speed. But there will have to be some repairs before we
+can do anything more with the air-ship."
+
+"Where'll we go to make them? Back to South Chicago?"
+
+"Lake Station is nearer. We'll come down there and ascertain the extent
+of the damage. It may be that we shall have to go back to South Chicago
+if the injury is at all serious."
+
+"All right," acquiesced Harris. "I'll be able to do some telephoning
+and get a few more men out here from headquarters. I'll have them bring
+rifles, and then we'll give Brady a set-to that he'll remember."
+
+"I ditn't see Matt in der blace," mourned Carl.
+
+"He may have been there," said Harris. "There were two sheds, and they
+may be keeping your chum a prisoner in one of them."
+
+"Vell, vile ve're avay fixing oop der Eagle, meppy dose fellers pack
+dere vill fly off mit demselufs in der Hawk. Oof dey do dot, den ve
+vill have some drouple for our pains."
+
+"We shall have to keep watch of the sky in the direction of the swamp,"
+said Jerrold. "By doing that we can tell whether or not the Hawk gets
+away."
+
+Carl made that his work.
+
+"I don'd know how I can see mit der naked eye ven ve ged py Lake
+Sdation," he remarked.
+
+"We'll have to hunt up a spyglass, or a pair of binoculars," suggested
+Harris.
+
+"Vat oof der Hawk moofs pefore we ged dem?"
+
+"Then we'll be up against it, and no mistake."
+
+There was a lot of excitement in the little town of Lake Station when a
+real, sure enough air-ship descended close to the blacksmith shop. The
+whole population gathered and stared.
+
+While Jerrold was busy tinkering with his crippled motor, Carl
+succeeded in finding an old-fashioned spyglass and climbed with it
+to the top of the highest building in town. There he perched himself
+on the edge of the roof and watched continually in the direction of
+Willoughby's swamp.
+
+Meanwhile, Harris had been talking with police headquarters in South
+Chicago. As a result, three officers were detailed to catch the first
+train for Lake Station.
+
+The repairs to be made to the Eagle were somewhat extensive, and taxed
+the capacity of the blacksmith shop. Had Jerrold been in his own
+workroom he could have fixed up the motor more easily and quickly, but
+to take the Eagle back to South Chicago would have resulted in a loss
+of time.
+
+Hour after hour the inventor labored, helped by the blacksmith and
+eyed with wonder by the townspeople. The detail of officers arrived,
+and they could do nothing but wait until the Eagle was ready to carry
+them to the "island" in the swamp. Any attempt to reach the "island" on
+foot was hardly to be considered.
+
+While Jerrold's labors were nearing completion, a yell from Carl called
+the attention of Harris.
+
+"What's the matter with you?" he shouted.
+
+Carl was dancing around on the roof top, waving the spyglass
+frantically.
+
+"Come oop!" he cried, wildly. "Der Hawk is gedding avay mit itseluf!
+Ach, plazes, vat a luck!"
+
+Harris made haste to reach the top of the building where Carl had been
+patiently waiting and watching.
+
+"Pud der spyglass to your eye, Harris," said Carl, "und look off to der
+nort'. Ach, dose fellers haf made some ged-avays, und I bed you dey
+have dook Matt along!"
+
+With the glass at his eye, Harris swept the horizon in the direction
+indicated by Carl. Finally he found what he was looking for--an
+oblong blot gliding through the heavens and proceeding in a northerly
+direction.
+
+"That's the Hawk, all right," said he, in a tone of intense
+disappointment, "but why is it heading in that direction?"
+
+"Prady vouldn't dare go pack by Sout' Chicago," said Carl. "I bed you
+somet'ing for nodding he has got anodder hang-oudt in dot tirections.
+Ach, vat vill I do for dot bard oof mine?"
+
+Gloomily the two descended from the roof, and Carl returned the
+spyglass to its owner.
+
+Half an hour later the Eagle was ready for flight, and the officers and
+Carl got aboard. It was decided to proceed to the swamp and look over
+the "island" and then, if nothing of importance developed, to return to
+South Chicago.
+
+The Eagle's motor, apparently, worked as well as ever, and the four
+miles separating Willoughby's swamp from Lake Station were covered in
+record time.
+
+As they neared the "island" the officers made ready to use their
+guns. There was no hostile demonstration, however, and not a soul was
+anywhere in sight. The Eagle descended, and the officers, accompanied
+by the anxious Carl, proceeded to make a search.
+
+They found nothing but two meagerly furnished houses, apparently
+recently deserted. Silence reigned everywhere, ominous of events that
+had happened.
+
+"Vell," said Carl, gloomily, "dis means dot I haf got to do some more
+looking for Modor Matt. Der gang haf made off mit him some more, und I
+vas so tisappointed as I can't dell."
+
+For that matter, they were all disappointed--Jerrold in particular.
+Motor Matt had served Jerrold well, and the inventor had been anxious
+to make him some repayment in kind.
+
+But there was nothing left for the air-ship party to do but to point
+the Eagle toward home. As the air-ship passed the rolling mills and
+came close to the balloon house where Brady had formerly housed the
+Hawk, it was observed by those in the car that the doors of the big
+building were closed, and that two officers had mounted guard in front
+of them.
+
+"That means something," muttered Harris. "Drop lower, Jerrold, so I can
+talk with those two cops."
+
+Jerrold descended until the top of the car was nearly on a level with
+the balloon house, and Harris leaned over the guard rail.
+
+"Hello!" he called. "What are you fellows doing there?"
+
+"Watching the air-ship," was the astounding answer.
+
+"Do you mean to say that Brady's air-ship is in that balloon house?"
+
+"Sure."
+
+"Has Brady been captured?"
+
+"Why, no. You went after him, didn't you?"
+
+"We went after him, but he and his men fired on us and damaged our
+motor. We went to Lake Station to fix the machinery, and while we were
+there we caught sight of the Hawk, through a spyglass, making north. As
+soon as we could, we started for the swamp, but there was no one there.
+Naturally, we supposed that Brady and his gang had made their escape,
+and it's mighty surprising to hear that the Hawk is back in its old
+cage and didn't bring Brady along."
+
+"The Hawk brought Motor Matt----"
+
+Carl gave a yell and nearly fell out of the car.
+
+"Modor Matt?" he shouted. "Vas you shdringing me, oder iss it shdraight
+goots?"
+
+"I'm giving it to you straight," answered the officer on the ground.
+"Motor Matt got away from the swamp and brought two prisoners with him,
+in the Hawk. They were two of the men who robbed Jerrold of his plans."
+
+"Zum lauderbach haben, mich shtets----" began Carl, singing loudly and
+then interrupting himself to gloat. "Dot's my bard vat dit dot! Yah,
+so! Leedle Modor Matt who iss alvays doing t'ings vat you don'd oxbect.
+He has shtarred himseluf some more, you bed you! Vere iss Modor Matt
+now, officer?" Carl called down.
+
+"He took a train into Chicago--said he was behind his schedule for that
+five-day race. The two prisoners are at police headquarters."
+
+"Well, by thunder!" muttered Harris, mopping his face with a red
+handkerchief, "that Motor Matt must be a regular young phenomenon!"
+
+"I never heard of anything to beat him!" averred Jerrold.
+
+"Und you nefer vill!" declared Carl. "He iss vone oof dose fellers vat
+can't be peat."
+
+"You might take us to police headquarters, Jerrold," suggested Harris.
+
+"Und you mighdt shtop on der vay py der railroadt sdation," piped Carl.
+"I vant to ged py Chicago so kevick as der nation vill led me."

+
+When Carl next saw Matt, the young motorist was spinning around the
+great oval in a Jarrot machine, which he knew so well and had driven
+to victory in Kansas. The five-day race was not for one driver alone,
+but several drivers were to be at the steering wheel of each car. Matt
+had reached the Coliseum just in time to take his place in the racing
+schedule.
+
+Every time Matt whirled around the oval, Carl had something to say
+to him, but it was not until evening that the boys were able to get
+together for a talk.
+
+They decided between them that Brady, and those whom Matt had left on
+the "island," must have made their escape from the swamp by a secret
+route known only to themselves.
+
+Where Harper, the driver of the Hawk was, was likewise a mystery to the
+police.
+
+Matt had turned the bag of loot stolen from Hartz & Greer over to the
+police with instructions to say that it was recovered by Miss Brady,
+and that no reward would be accepted for its return.
+
+"How you tink dot air-ship pitzness is, anyvays, Matt?" asked Carl,
+when the boys had had their talk out and were ready to crawl into bed.
+
+"I _like_ it," answered Matt, enthusiastically, "and I wish I could
+have more of it!"
+
+His wish was destined to fulfillment, for, as events proved, his
+thrilling work in South Chicago and at Willoughby's swamp was but
+the beginning of a series of air-ship experiences. Matt may have
+congratulated himself with the thought that he was through with Hector
+Brady, but Brady was by no means done with Matt--as will be made clear
+in the story to follow.

+
+
+
+THE BIG CYPRESS.
+
+
+The rifle cracked and the piece of boiler plate, which had been erected
+as target against the bank fifty yards away, fell shattered like a pane
+of glass.
+
+"How's that, Colonel Fearon?" coolly inquired the young fellow, who had
+fired the shot, as he turned to the tall, sallow-faced man who stood
+beside him.
+
+A curious expression crossed the latter's face, but he answered
+quickly, "Amazing, Rutherford! Simply astonishing. I could never have
+believed such a thing possible. A pom-pom shell could hardly have
+smashed the plate more effectually."
+
+The boy--he was hardly more--laughed. "I thought it would startle you,
+colonel. Will you feel justified in sending me up to Washington?"
+
+"I reckon that's the place for you to go to, Rutherford. The war
+department'll need that new bullet of yours in their business. You mean
+to tell me you invented that bullet all by yourself?"
+
+"I did, colonel. You see, I was always fond of dabbling in chemistry
+and the idea for this came to me one day when I was at work in my
+father's store. I didn't worry about it much, until the poor old man
+went broke, and then it struck me there was money in it. It was the
+mayor of our town, Orangeville, told me to come to you. He said that
+you could give me the proper introductions."
+
+"He was right," said Colonel Fearon. "I can fix you up with the proper
+people. Let me have a shot."
+
+Lionel Rutherford handed the colonel a cartridge, which outwardly
+looked precisely similar to an ordinary rifle cartridge. He then walked
+across the lawn of fine Bermuda grass, put a fresh piece of steel plate
+in position, and came back.
+
+The colonel fired, and, as before, the tough steel simply sprang to
+pieces and lay in scattered fragments on the grass.
+
+"I reckon there's more money in this than in keeping store," said the
+colonel thoughtfully. "Rutherford, I'll be pleased if you'll stay here
+at my house for a day or two till I can write to the proper people."
+
+Young Rutherford thanked him warmly and the two walked back toward the
+long, low, wide verandaed house.
+
+Late that night the colonel and his son, Randal Fearon, sat together in
+the well-appointed smoking room and talked earnestly in low tones.
+
+"There's thousands in it, father," said the younger man sharply.
+"Thousands!"
+
+"I know that as well as yourself," returned the other irritably. "But
+the invention's not yours or mine."
+
+"What's Rutherford?" sneered Randal. "Here he is, a fellow who's never
+known anything of life, who's lived all his days in a little one-horse
+backwoods town, and now he's going to roll in riches while we are on
+the edge of bankruptcy."
+
+He paused, and glanced at his father, who sat fidgeting uneasily. The
+colonel, fine-looking man that he was, was as weak-willed as his tall,
+thin, sharp-faced son was strong.
+
+"A real nice scandal there'll be when we go smash," went on Randal
+Fearon. "Think of the headlines. 'Fraudulent Bankruptcy. Prominent
+Floridian lives beyond his means.' How the yellow press'll revel in it!"
+
+Again the colonel moved uneasily. "I don't see how you're going to get
+the specifications from him, anyhow," he said at last.
+
+"You leave that to me," replied Randal with sneering emphasis.
+
+"Look you here, Randal, I won't have any violence." For once Colonel
+Fearon spoke decidedly.
+
+"I guess you needn't worry your head about that," answered Randal.
+"I've got the whole plan cut and dried. You've asked him to stay?"
+
+"Yes," said the colonel. "He will stay."
+
+Randal laughed as if pleased. "That's all right. To-morrow we'll settle
+it, Pete Dally and I."
+
+"How?"
+
+"I'll tell you in the morning. Don't worry yourself. As you are so
+anxious to avoid it, I promise you there shall be no violence."
+
+Randal chuckled in ugly fashion as he got up, flung the stump of his
+cigar into the fireplace, and, lighting a small hand lamp, left the
+room.
+
+       *       *       *       *       *
+
+"How much farther have we got to go before we run into any of this game
+you talked about, Mr. Fearon?" asked Rutherford as he stopped and wiped
+the perspiration from his streaming face.
+
+"I thought we'd have seen a buck before now," replied Randal Fearon.
+"We don't often have to come this far into the Big Cypress to find
+game, do we, Pete?"
+
+"No, sah; we gen'rally finds it quite clos' to the aidge of de swamp,"
+said Pete, who was a burly, square-shouldered negro with a face as
+black as ebony.
+
+Rutherford was rather puzzled. That morning Randal Fearon had suggested
+that it would be very good fun to go shooting in the Big Cypress, a
+huge tract of wild, swampy forest, the edge of which was about five
+miles from Colonel Fearon's place.
+
+"You might try the effect of some of your explosive bullets," Randal
+had suggested; and Rutherford had laughed and said that there wouldn't
+be much left of any game smaller than a buffalo or an elephant if
+struck by one of his projectiles.
+
+All the same, being a keen sportsman, he had willingly agreed to the
+shoot. What puzzled him was that they should have tramped for hours
+through this steaming bush, which reeked with signs of game, and yet
+not seen a single thing to shoot at.
+
+"Don't you worry. We shall find deer soon," said Randal when Rutherford
+expressed his astonishment. "We're getting near a good place now. I
+reckon we'd better stop and eat our dinner first. Pete, make a fire."
+
+Pete Dally dropped the big haversack he was carrying over his broad
+shoulders, and obeyed. In a very few minutes a fire was blazing,
+and the fragrant fumes of frying bacon and strong coffee filled the
+close, steamy air. Lionel Rutherford, tired by the long tramp and the
+hot-house atmosphere of the jungle, enjoyed the meal greatly.
+
+After they had finished they marched on again. They had left the pine
+trees behind, and were pushing along a narrow track through a forest
+of great ilex, bastard oak, and magnolia. The undergrowth was of saw
+palmetto, growing in huge, impenetrable clumps, among which the muddy
+track wound in and out.
+
+The scent of yellow jasmine was almost stifling, but the only life
+visible was an occasional cardinal bird with its vivid crimson
+plumage, or a stub-tailed water moccasin which raised its triangular,
+copper-hued head with an ugly hiss and dragged itself sluggishly out of
+sight among the tangled herbage.
+
+The path was so narrow that they were compelled to walk in single file.
+Randal made Pete lead the way. More than once the negro had tried to
+drop behind, but each time Randal roughly ordered him to push ahead.
+
+The silence of the swamp grew as oppressive as the intense heat. It
+began to get upon young Rutherford's nerves.
+
+"A tough place to get lost in," he said at last.
+
+Randal turned quickly. There was a queer expression on his sharp face
+as he replied:
+
+"Yes, pretty bad, I reckon."
+
+Somehow, Rutherford fancied there was something sinister in his tone.
+
+"I don't like the chap," he thought to himself. "I wish I hadn't come."
+Then common sense got the better of his fears. "It's the place, not the
+people, that's worrying me. These big hamaks are worse than a desert.
+There you can see the sky; here it's like one great, green prison."
+
+"Look out, sah. Dah's a wild cat in dat tree," suddenly hissed Pete
+Dally, and slipped out of the path into the thicket. "Quiet or youse
+done frighten him."
+
+Rutherford, all excitement, slipped his rifle from his shoulder.
+
+But Randal barred his way. He was standing still, peering up into the
+tree indicated.
+
+"Where? I don't see it," he exclaimed harshly.
+
+"Dere it am, sah. On dat big fork," declared Pete, pointing. And then
+as Randal stepped forward, the negro slipped back round a clump of
+palmetto, and Rutherford felt a hand fall sharply on his arm, while
+these words were whispered in his ear:
+
+"Dat man mean you no good, sah. Watch me, an' doan' do what he say."
+
+He turned in amazement, but Peter was already gone. He had glided back,
+and was standing at Randal's elbow, pointing out the exact spot where
+he alleged he had seen the cat.
+
+But there was no cat there now, and Rutherford wondered if there ever
+had been. Randal cursed Pete angrily, and once more they moved forward.
+
+Rutherford, more worried than he cared to own even to himself,
+followed, as before, the last of the little procession.
+
+It was getting late and the bullfrogs had begun to bellow harshly in
+unseen pools in the forest. But there was no decrease in the sullen
+heat. Not a breath stirred the moist, stagnant air, and the farther
+they went the thicker grew the tangled vegetation till there was no
+longer any sign of a path. In unbroken silence the three forced their
+way through primeval forest.
+
+Presently trees broke away, and they stood upon the muddy marge of a
+reedy lagoon, across the stagnant waters of which the low sun cast a
+lurid light.
+
+"Here we are," said Randal Fearon sharply. "This is where the deer come
+down to drink. You wait, Rutherford, in the bushes here, and you'll
+soon get a shot. Pete and I will take up our places on the far side.
+Then whatever comes some of us will get a buck."
+
+"Watch me, and don't do what he says." Pete's words were ringing in
+Rutherford's ears. He cast a glance at the negro. Pete made a quick
+sign, which the English boy took to mean that he was to follow instead
+of remaining.
+
+Next moment Randal had plunged off through the palmetto with Pete at
+his heels.
+
+"What's it all mean?" muttered Rutherford angrily. "Is Fearon fooling
+me, or is it Pete? Of the two, I infinitely prefer the nigger. I'll do
+what he says."
+
+He left his shelter, and moved as quietly as possible on the track of
+the other two.
+
+Sure enough, they did go round the pool! Rutherford began to wonder if
+he was wrong; whether Pete for some unknown reason was fooling him.
+
+The going was dreadful. The ground below the almost impenetrable
+palmetto was deep mud. Swarms of mosquitoes rose and stung viciously.
+Lionel was afraid that the crashing of the parted bushes would betray
+him.
+
+He knew he was falling a long way behind, and panic seized him that he
+might lose the others. Though young Rutherford had lived all his life
+in America, yet he had never been in a big swamp like this. The store
+had kept him busy.
+
+At last he reached the spot which Randal had pointed out as his own
+shooting station. To his horror, there was no one there. Randal and
+Pete had both disappeared. He was alone in the tangled heart of this
+monstrous swamp, and knew that without help he could never hope to find
+his way out.
+
+After the first moment of panic Lionel Rutherford pulled himself
+together. He had plenty of pluck. He rapidly considered the situation.
+For some reason best known to himself Randal Fearon wished to abandon
+him, to lose him in the swamp. But he himself had no idea of dying of
+hunger, fever, or snakebite in this impenetrable wilderness. He had two
+courses open--go back and try to find his way out along the trail they
+had come by, or follow after Randal and Pete.
+
+There were no objections to the first. It was a very long way, and it
+was doubtful if he could find it even in broad daylight. As it was,
+it would be dark in an hour. Besides, Pete had certainly meant him to
+follow.
+
+Randal must mean to spend the night in the swamp. That was clear.
+Therefore he must have some camping place.
+
+"I'll follow," muttered the boy between set teeth, and started off.
+
+Though the sun was not yet down, it was already dusk beneath the thick
+shade of the towering timber, and in the half light the trail was most
+difficult to follow. The others had long ago passed out of hearing.
+
+The night life of the swamp was waking. Enormous owls hooted weirdly,
+then came the thundering bellow of a bull alligator, and presently
+above all these the ghastly, half-human shriek of a panther calling to
+its mate.
+
+Stumbling and struggling, Lionel hurried on. In a little he came to a
+thick belt of tall saw grass. The two pairs of footmarks entered it,
+but the trails beyond were so confused with the passage of deer and
+other animals that the boy recognized with a shock that he could not
+follow the human footsteps.
+
+Very near despair, he turned back. No, he could not find Randal's
+trail. He stopped. "I'm done!" he muttered hopelessly, and stood
+straining his ears for any sound of his former companions.
+
+Just then, as he was almost giving up, he caught sight of a morsel of
+something white stuck on a broken stem beside the trail. It was a tiny
+piece of paper, and on it, marked with a muddy finger tip, an arrow
+pointing in a certain direction.
+
+"Pete!" exclaimed Lionel joyfully. A load rolled off his mind. Marking
+the direction carefully, he pushed on fast. Now he was on the lookout,
+he found other signs; a broken twig, a stick, laid in the path.
+
+Darkness fell rapidly. There is little twilight in Florida.
+
+"They can't go much farther," he said. He was right. In a very short
+time the dull glow of a fire showed where the others had camped.
+
+"What shall I do?" he asked himself. "Go right up and tackle Randal
+Fearon? No; he'd have some excuse ready, and I'd only get Pete into
+trouble. I must wait till Randal goes to sleep."
+
+The mosquitoes were savage. Young Rutherford, tired and hungry, found
+it maddening to wait in the damp gloom, and watch Randal gorge on the
+supper which Pete cooked. Nearly two hours passed before Randal, having
+finished a cigar, rolled himself, head and all, in a blanket and lay
+down.
+
+A few minutes more, and a snore told Rutherford it was safe to venture
+closer.
+
+Pete heard him, and glided out. The black man chuckled silently when he
+saw the boy. "Reckoned you'd be along, sah. You foun' de sign Pete lef'
+for you. Now de firs' thing is you eat. Den we talk."
+
+He put corn, bread, and bacon into Rutherford's hands, and the boy made
+a hearty meal.
+
+"Now, sah," said Pete. "You see what dat man want to do. He lose you in
+de swamp, den go home, say you fell in de water and was drowned. Den he
+an' his dad, dey take dat blow-up bullet ob yours an' sell him."
+
+Lionel Rutherford was aghast. He had never dreamed of such wickedness.
+
+"But we beat dem," went on Pete, with a chuckle. "I like you, an' I
+hate dat Randal."
+
+"What can we do?" asked Lionel eagerly.
+
+"Why, we play de same trick on him he try play on you. We take all de
+stuff, go off, an' leab him. He no more find his way out of de Big
+Cypress dan you. Only Pete know de trails."
+
+"That won't do, Pete," returned Lionel sharply. "I won't be any party
+to murder."
+
+Pete was amazed. He expostulated strongly.
+
+"No, I'll tell you what we will do, Pete. We'll go off and hide, and
+let him think he's lost. We'll follow and watch, and when he's got the
+soul nearly scared out of him we'll find him again. See?"
+
+Pete saw. He chuckled again in high good humor. "Dat's a very fine
+game, sah. We play dat to-morrow morning. Now I take de things away,
+an' when Randal wake he find no breakfast, no Pete, no nothing."
+
+       *       *       *       *       *
+
+"He done lost hisself, sure pop!" declared Pete.
+
+It was nine o'clock next morning, and Lionel Rutherford and the negro
+had been following Randal for more than an hour.
+
+His language when he woke up and found Pete gone had been something
+appalling.
+
+Having found that this did no good, he had started off back along
+the track they had come by on the previous day, but in less than
+ten minutes he was off it; and the two, who followed at a discreet
+distance, had watched his growing fury and fright when he found himself
+quite lost in the pathless depths of the wilderness.
+
+"He can't go dat way much furder," observed Pete. "He gettin' down in
+de deal bad swamp. He go in up to his fool neck if he don't be keerful."
+
+Sure enough the quaking muck-land broke beneath the young scoundrel's
+weight, and in he went. With a yell of fright he caught at a branch,
+pulled himself out, and staggered back.
+
+"What's he going to do now?" whispered Lionel.
+
+"Reckon he going climb dat tree an' see whar he am."
+
+Pete was right. Randal began shinning up the stem of a tall, slender
+tree by the water's edge, the only one which seemed to give a possible
+view of any of the surrounding country. No doubt he thought he might
+spot the trail from the summit.
+
+Rutherford, who had been staring hard at the tree, suddenly clutched
+Pete's arm. "What's that thing up in the branches just above him?" he
+asked sharply.
+
+Pete took a long stare. "By golly, sah, it am a snake! An' a mighty big
+one, sure!"
+
+Rutherford started forward, slipping a cartridge into his rifle.
+
+"Don't shoot, sah," whispered Pete. "Dat ain't no poison snake. It am
+only a old white oak snake."
+
+"Looks like an ugly customer," muttered Lionel.
+
+At this moment Randal reached the first boughs and stood up. The
+movement alarmed the snake, which raised its ugly head and hissed
+sharply.
+
+Randal heard the hiss, and, turning, saw the reptile. He gave a scream
+of terror, and almost lost his hold. Then he backed rapidly on to a
+branch which actually overhung the creek.
+
+"Time to end this now," said Rutherford, raising his rifle. "I shall
+shoot the snake."
+
+Pete seized his arm. "De snake won't hurt him, sah. But dey will."
+
+He pointed to the water. The big alligator had seen Randal, and
+silently moved up till it was just beneath him. Another of almost equal
+size had also risen to the surface. Yellow eyes agleam, the hideous
+brutes were watching for this rash intruder upon their domain.
+
+At the very instant there was a snapping crackle. The bough on which
+Randal cowered was breaking. And the wretched man, clinging vainly for
+a hold, had caught sight of the huge reptiles below. He screamed till
+the forest resounded with his agonizing cries.
+
+He snatched at the branches above, but could reach only twigs, which
+broke in his grasp. He was falling clean into the open jaws of the
+alligators.
+
+If Rutherford's rifle had been loaded only with an ordinary cartridge
+nothing could have saved Randal. It was just pure luck that he had
+flung one of his explosives into the breech.
+
+Simultaneous with Randal's fall the rifle spoke. The bullet caught the
+nearest alligator on the side of the head, and the air was full of
+mangled fragments of flesh and bone.
+
+Into this horrible geyser Randal dropped heavily and vanished.
+
+Next moment he rose again, and struck out madly for the bank.
+
+"I can't shoot again," cried Lionel. "I should kill him if I did."
+
+"Dere ain't no need to," said the negro. "You done scared de stuffin'
+out ob dat oder gator."
+
+"Thank goodness he's safe," exclaimed Lionel as Randal scrambled ashore
+and fell in a heap on the bank. "Now we'd better get him home."
+
+Pete laughed. "Yes, sah. I reckon he done had enough ob de Big Cypress."
+
+When Randal came round Rutherford soon realized he had no more to
+fear. The fellow's nerve was broken. He shivered and trembled like a
+frightened child.
+
+They took him home, and then Lionel went boldly to Colonel Fearon, and
+told him the whole story plump and plain. When he had finished the
+colonel sat speechless. His face was gray and pinched.
+
+Lionel looked at him. "I shan't make any trouble for you," he said
+coolly. "All I want is those introductions. Write them now, and I'll
+take them myself to Washington."
+
+Without a word the colonel obeyed.
+
+Lionel Rutherford is now a rich and rising man. Pete is his faithful
+major-domo. Whenever Lionel gets a holiday the two go off down south
+for a week or two of shooting. But they never again penetrated the
+desolate depths of the Great Cypress.

+ADVENTURES OF A BOY GENIUS
+
+MOTOR STORIES
+
+
+Most five-cent weeklies are founded upon the adventures of boy wonders
+who perform all sorts of impossible feats and who never act or talk as
+a boy really does. This is displeasing to the intelligent boy of the
+present day, who is better educated, and who, consequently, demands
+more logical reading than the old-time boy did.
+
+The boys who want to learn something from what they read, as well
+as to be interested by it, will never find another publication that
+will satisfy them so well as MOTOR STORIES. "Motor Matt" is not an
+impossible boy character. He is simply a youth who has had considerable
+training in a machine shop where motors of all kinds were repaired,
+and who is possessed of a genius for mechanics. His sense of right and
+wrong is strongly developed, and his endeavors to insure certain people
+a square deal lead him into a series of the most astonishing, but at
+the same time the most natural, adventures that ever befell a boy.
+
+Buy the current number from your newsdealer. We feel sure that you
+will be just as enthusiastic about it as the fifty thousand other boys
+throughout the United States have become.

+Creating the works from print editions not protected by U.S. copyright
+law means that no one owns a United States copyright in these works,
+so the Foundation (and you!) can copy and distribute it in the United
+States without permission and without paying copyright
+royalties. Special rules, set forth in the General Terms of Use part
+of this license, apply to copying and distributing Project
+Gutenberg-tm electronic works to protect the PROJECT GUTENBERG-tm
+concept and trademark. Project Gutenberg is a registered trademark,
+and may not be used if you charge for the eBooks, unless you receive
+specific permission. If you do not charge anything for copies of this
+eBook, complying with the rules is very easy. You may use this eBook
+for nearly any purpose such as creation of derivative works, reports,
+performances and research. They may be modified and printed and given
+away--you may do practically ANYTHING in the United States with eBooks
+not protected by U.S. copyright law. Redistribution is subject to the
+trademark license, especially commercial redistribution.
+
+START: FULL LICENSE
+
+THE FULL PROJECT GUTENBERG LICENSE
+PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK
+
+To protect the Project Gutenberg-tm mission of promoting the free
+distribution of electronic works, by using or distributing this work
+(or any other work associated in any way with the phrase "Project
+Gutenberg"), you agree to comply with all the terms of the Full
+Project Gutenberg-tm License available with this file or online at
+www.gutenberg.org/license.
+
+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 unprotected by copyright law 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 in the United States and
+  most other parts of the world 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. If you are not located in the
+  United States, you'll have to check the laws of the country where you
+  are located before using this ebook.
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is
+derived from texts not protected by U.S. copyright law (does not
+contain a notice indicating that it is posted with permission of the
+copyright holder), the work can be copied and distributed to anyone in
+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.
+
+1.E.8. You may charge a reasonable fee for copies of or providing
+access to or distributing Project Gutenberg-tm electronic works
+provided that
+
+* You pay a royalty fee of 20% of the gross profits you derive from
+  the use of Project Gutenberg-tm works calculated using the method
+  you already use to calculate your applicable taxes. The fee is owed
+  to the owner of the Project Gutenberg-tm trademark, but he has
+  agreed to donate royalties under this paragraph to the Project
+  Gutenberg Literary Archive Foundation. Royalty payments must be paid
+  within 60 days following each date on which you prepare (or are
+  legally required to prepare) your periodic tax returns. Royalty
+  payments should be clearly marked as such and sent to the Project
+  Gutenberg Literary Archive Foundation at the address specified in
+  Section 4, "Information about donations to the Project Gutenberg
+  Literary Archive Foundation."
+
+* You provide a full refund of any money paid by a user who notifies
+  you in writing (or by e-mail) within 30 days of receipt that s/he
+  does not agree to the terms of the full Project Gutenberg-tm
+  License. You must require such a user to return or destroy all
+  copies of the works possessed in a physical medium and discontinue
+  all use of and all access to other copies of Project Gutenberg-tm
+  works.
+
+* You provide, in accordance with paragraph 1.F.3, a full refund of
+  any money paid for a work or a replacement copy, if a defect in the
+  electronic work is discovered and reported to you within 90 days of
+  receipt of the work.
+
+* You comply with all other terms of this agreement for free
+  distribution of Project Gutenberg-tm works.
+
+1.E.9. If you wish to charge a fee or distribute a Project
+Gutenberg-tm electronic work or group of works on different terms than
+are set forth in this agreement, you must obtain permission in writing
+from both the Project Gutenberg Literary Archive Foundation and The
+Project Gutenberg Trademark LLC, 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
+works not protected by U.S. copyright law in creating the Project
+Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
+electronic works, and the medium on which they may be stored, may
+contain "Defects," such as, but not limited to, incomplete, inaccurate
+or corrupt data, transcription errors, a copyright or other
+intellectual property infringement, a defective or damaged disk or
+other medium, a computer virus, or computer codes that damage or
+cannot be read by your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+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 MERCHANTABILITY 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 information page at
+www.gutenberg.org
+
+
+
+Section 3. Information about the Project Gutenberg Literary Archive Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Contributions to the Project Gutenberg Literary
+Archive Foundation are tax deductible to the full extent permitted by
+U.S. federal laws and your state's laws.

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