The Boy Aviators

with the Air Raiders

Captain Wilbur Lawton

CHAPTER I.

NOT FAR FROM THE FIRING LINE.

“It seems queer not to have Harry along with us on this trip to the war zone of Europe!”

“Just what Pudge, here, was saying last night, Billy. But you know my brother Harry has been ordered by Doctor Perkins to keep quiet for two whole months.”

“Frank, he was lucky to break only his arm and collar bone, when it might have been his neck, in that nasty fall. But why are you rubbing your eyes like that, I’d like to know, Pudge Perkins?”

“Pirates and parachutes, I’ll tell you why, Billy. Every little while I get to thinking I must be dreaming. So I pinch myself, and dig my knuckles in my eyes to make sure. But it’s the real thing, isn’t it, boys?”

“If you mean that the three of us, here, representing the Sea Eagle Company, Limited, of Brig Island, in Casco Bay, Maine, makers of up-to-date seaplanes, have come over to look up a sample shipment of our manufactures, and find ourselves being pestered by the French and British Governments to take a contract from them, why it certainly is the real thing.”

“It was lucky my father has that arrangement with the French Government to protect our property through thick and thin,” continued the boy called Pudge, who, as his name would signify, was very rotund in build, with a rosy face, and a good-natured twinkle in his eyes.

“Yes, only for that they would have commandeered the boxed seaplane long ago, and by now dozens of fleets made on the same model would be pouncing on the German bases along the Belgian coast,” remarked the boy whose name was Frank, and to whom the other two evidently looked up as though he might be their leader in the enterprise requiring skill and courage.

“But they’ve been mighty good to us since then,” went on Pudge. “They have allowed us to have a substantial hangar built after our own peculiar pattern within reach of the water here at Dunkirk, though we are not so many miles away from where the Allies are fighting the Kaiser’s men who are in Belgian trenches.”

“Yes,” added Billy Barnes, who had once been a lively reporter, now a member of the aëroplane manufacturing company engaged in making the remarkable type of airships invented by Pudge’s scientific father, Doctor Perkins, “and during these weeks we’ve been able to get our machine together, so that right now it’s in prime condition for making a flight on the sea or in the air.”

“Whisper that next time, Billy,” cautioned Frank, casting a quick glance about him as the three boys continued to walk along the road leading out of Dunkirk, which in places even skirted the water’s edge.

“Why, what’s up, Frank?” exclaimed the talkative Billy. “Do you think these bushes and trees have ears?”

“No, but there might be some sharp German spy hanging around this place,” replied the other earnestly. “You know they do say they’re everywhere. I’ve heard British soldiers in Calais and Dunkirk tell of mysterious strangers who disappeared when approached as if they were made of smoke. This spy system the Kaiser’s men have down to a fine point. It’s hard to keep anything from being carried to German Headquarters these days.”

“Still, there are a lot of things they haven’t learned before they happened,” declared Billy. “That first British army of some eighty thousand soldiers came over to France, and nobody knew a thing about it until they were on the firing line. But, Frank, do you reckon the Germans have been watching the three of us working here with our hangar and hydro-aëroplane?”

“I’m as sure of it as I am of my own name,” declared the other firmly. “Why, the very fact that our hangar differed so much from ordinary ones, being so much larger for one thing, would make them suspect. Then there has been a heap of talk going on about this wonderful airship of ours, which was carried, every word of it, to German Headquarters.”

“Batter and butterflies!” spluttered Pudge, who seemed addicted to strange exclamations, especially when excited, “we’ll certainly have to watch out, then, now that our wonderful Sea Eagle is in working order.”

“Yes,” said Billy Barnes earnestly, “it would be a tough joke on the company to have some clever thieves get away with it, just when we are ready to show the French Government that it is away above ordinary seaplanes.”

“There’s the hangar, boys,” remarked Frank, with a vein of relief in his voice, as though grave fears may have been giving him more or less uneasiness. “Stir your stumps, Pudge, and we’ll soon be under our own roof. I may have a suggestion to make after we’ve looked around a bit that I hope both of you will agree with.”

While the three chums are advancing on the strangely elevated building that had been erected to accommodate their seaplane, we may take advantage of the opportunity to glance backward a bit, in order to see who and what they were. We do this for the benefit of those readers who may not have had the good fortune to peruse previous volumes in this series.

Two bright, inventive brothers, New York boys, who had actually built an aëroplane which they named the Golden Eagle, had shipped it to Central America when given a chance to save a plantation owned by their father, and threatened by the revolutionists in Nicaragua. This they had managed to accomplish, through the assistance of a young reporter friend named Billy Barnes. In this book, which was called The Boy Aviators in Nicaragua, were also related the thrilling adventures that befell the young air pilots when their craft was carried out to sea in an electrical storm; and also how they were rescued by means of a wireless apparatus through which they communicated with a steamer.

In the second volume, The Boy Aviators on Secret Service, the reader was taken to the mysterious Everglades region of Florida where the young inventors once more demonstrated their ability to grapple with emergencies. They proved that they were patriotic sons of Uncle Sam by discovering and putting out of commission a factory that was making dangerous explosives without the consent of the Washington Government.

It was a long jump from Florida to the depths of the Dark Continent, but the occasion arose necessitating their taking this trip to Africa. If you want to learn how theirs was virtually the first aëroplane to soar above the trackless heart of Africa, how they found the hidden hoard of priceless ivory secreted by slavers in the wonderful Moon Mountains, what strange things came about through their being hunted by the vindictive Arab slave trader, with many other interesting adventures, you can do so by procuring The Boy Aviators in Africa.

Through the coaxing of their warm chum, Billy Barnes, the boys were next induced to enter in a competitive race across the continent, and it can be easily understood that the pages of this book, The Boy Aviators in Record Flight, fairly teem with exciting incidents and thrilling adventures. Crossing the great Western cow country, they met with many difficulties from sand storms to treacherous cowboys and renegade Indians that threatened to end their game voyage. But the same indomitable spirit that had carried Frank and Harry through so many trials allowed them to meet with the glorious success they so richly deserved.

From one series of adventures like this it was easy for the wide-awake young air pilots to engage in others. A story of an old Spanish galleon caught in the grip of that mysterious Sargasso Sea, where the circling tides have held vessels amidst the floating grass for centuries, fascinated them, and they set out to explore the dismal region that has been the graveyard for countless ships. Of course, the lure lay in the fact that a vast treasure was said to be aboard this old galleon; and the hunt for it, together with the opposition caused by a rival expedition, makes great reading for boys who have red blood in their veins. It is all set down in The Boy Aviators’ Treasure Quest, which has been voted one of the best of the entire series.

The Boy Aviators’ Polar Dash was possibly the most remarkable example of Young America’s nerve ever written. How the brothers came to plan the trip to the Antarctic region, and what amazing things happened to them while carrying it out, you will certainly appreciate when you read the book. The object of the expedition was fairly covered, and they came back in safety; but only for the aëroplane the result could never have been attained, which proved how valuable an airship might be amidst the eternal ice of the frozen zones.

In the volume following this, the boys again found themselves caught in a swirl of exciting events. They had become engaged to Doctor Perkins, who was not only a scientific gentleman of note but particularly an aviator bent on startling the world through the agency of a monster seaplane which he had invented. He believed that a voyage across the ocean could easily be made in one of his safe aircraft, which combined many features not as yet in common use among the most advanced aviators. On Brig Island in Casco Bay, within sight of the Maine coast, they erected their factory, and manufactured various types of aëroplanes for the market. So far this wonderful seaplane had not been given to the world, for Doctor Perkins was shrewd enough to first get his patents in all foreign countries in order to protect his interests. In The Boy Aviators’ Flight for a Fortune have been related a series of remarkable adventures that befell the young air pilots when trying out the first of these enormous hydro-aëroplanes, that would skim along the water or sail through the air with equal swiftness and safety.

One of these enormous seaplanes had been boxed in sections and shipped over to France, with the design of giving the Government officials an actual exhibition before they would agree to making a large contract with the firm.

Then the terrible world war had broken out, and for some months it was not known just what had become of the precious machine.

Finally word was received that it was safe at Havre, under the protection of the French Government, which would adhere strictly to the letter of the written agreement which they had entered into with the American company.

An urgent request was sent across the sea for some competent aviators to come over and put the several parts together, so that an actual test could be made. The French Government, if the trial proved convincing, stood ready to make almost any kind of contract with the company. This would be either in the way of ordering a large number of seaplanes, providing they could be delivered without breaking the neutrality laws binding the United States, or else giving a royalty on each and every machine manufactured in France under the patents granted to the doctor.

This necessary but brief explanation puts the reader, who may not have previously known Frank and his chums, in possession of facts concerning their past. While Pudge Perkins, the doctor’s son, was not an experienced aviator, he had picked up more or less general knowledge in the factory, and had come abroad with Frank and Billy, as he was accustomed to say, just to “keep them from dying of the blues, in case the French Government kept putting them off from week to week, or if anything else disagreeable happened.”

Indeed, Pudge, with his abounding good nature, his love for fun, and great capacity for eating, might be looked upon as a pretty fine antidote for the dread disease known as the “blues.” No one could long remain depressed in mind when he was around. Besides, Pudge was really smarter than he looked; appearances in his case were apt to be deceptive; for the boy had a fund of native sagacity back of his jolly ways.

Their hangar had been built in a rather lonely spot close to the water. This was done for several purposes, chief among which might be mentioned their desire to avoid publicity.

The obliging French authorities had even placed a guard at the point where the road passed the open spot now enclosed with a high fence; and so effectual had this proved that up to now the Americans had really not been annoyed to any extent.

Frank, however, had known for some time that all their movements were being watched from different elevated stations in the way of hilltops, or the roofs of houses, by men who carried field glasses. He had many times caught the glint of the sun on the lens when a movement was made.

As long as it went no further than that Frank had not cared, because these suspected spies could see next to nothing. But of late serious fears had begun to annoy him. The seaplane was ready for its first trip, and in a condition where it might be stolen, if a band of daring men took it into their heads to make the attempt.

At one end of the hangar a long track with a gradual slope ran down to the water, so that the seaplane could be launched in that way if desired. A narrow stairway on the land side led up to the stout door which they always kept fastened with an odd padlock capable of resisting considerable pressure.

Each one of the three boys had a key for this lock, which they were very careful to keep fastened to a steel pocket chain. Pudge, having mounted the stair first, puffing from the exertion, was about to insert his key in the padlock when he was heard to utter an exclamation. The others saw him look closely, and then turn upon them with an expression of mingled alarm and consternation on his round face.

“As sure as you live, boys,” the stout boy gasped, “that’s a bit of wax sticking to our padlock! Someone’s been taking an impression so as to have a duplicate key made!”

CHAPTER II.
 
THE WORK OF GERMAN SPIES.

When that astonishing declaration made by Pudge told the other two boys the nature of his discovery, they also glanced at the suspicious atom of wax sticking to the brass padlock.

“Sure enough, Frank; that it is,” gurgled Billy Barnes.

“There’s no question about it,” admitted Frank, as he took the fragment between his thumb and forefinger, and examined it.

“It wasn’t here when we came around this morning, I’d take my affidavy to that,” declared Billy.

“Dories and dingbats, not a bit of it!” exclaimed Pudge. “That padlock was as clean as a whistle, for I rubbed it with my sleeve to brighten it. There’s been some one snooping around here since then; and I guess they must mean to come back again to-night to steal the seaplane!”

“Open up, and let’s make sure things are all right still,” demanded Frank. “We can settle on some sort of plan to upset their scheme by putting on a new lock, or something like that.”

Pudge, with a trembling hand, managed to insert his key, and upon the door being opened the three boys hurried inside the curious elevated hangar. It had been built with a metal roof, though whether this would really prove bombproof in case of a German air raid, such as had occurred several times, was a question.

“Thank goodness! everything seems to be O. K., boys!” cried Billy, after he had taken a swift survey of the interior, including the monster seaplane built on so advanced a model that there was certainly nothing like it known to aviators.

Frank, too, breathed more freely, for he had not known what to expect.

“Yes,” he went on to say earnestly, “and we ought to be mighty thankful that we’ve managed to get along up to now without having our whole outfit wrecked by a bomb, set on fire by a German spy, or raided some night by a party of unknown persons who would have an interest in keeping the French Government from getting this sample seaplane.”

“My idea is this,” remarked Billy soberly. “They could have done the mischief at almost any time, but some one in authority thought it would be a brighter idea for them to wait until we had finished working on the plane, and then steal it, so that the Germans could copy our model for their army.”

“Gatling guns and grasshoppers, but I think you must be right, Billy,” exploded Pudge. “Haven’t we known that they kept a steady watch on us while we worked away here, even if they couldn’t see much? And many a time we disputed whether those chaps were German spies, or Frenchmen set on guard so as to make sure we didn’t take a notion to fly away some day to the enemy.”

Frank was looking unusually serious, and it could be plainly seen that he had a weight on his mind. The afternoon was near its close; and before long the shadows of a dark February night would be closing in around them.

“One thing sure, boys,” he finally said, “we must not leave our seaplane unguarded another night.”

“Do you think they mean to make away with it tonight, Frank?” demanded Billy.

“In some way they seem to know we’ve finished our work,” came the reply. “It puzzles me to guess how they learned it, when we only this noon notified the French authorities in secret that we were ready for any sort of long-distance test they might wish to order.”

“Must be a leak at Headquarters!” suggested Billy quickly.

“Tamales and terrapins, that would be a nice proposition, I should think!” ejaculated Pudge.

“Let’s step out and look around a little,” suggested Frank. “Perhaps we may find some trace of these unwelcome visitors who have managed to get up here to our door in spite of the soldier standing guard by the gate of our stockade.”

“They must have come from the water side, Frank,” Pudge was heard to say as he followed the others down the stairway that led to the ground.

“Be careful how you step around,” cautioned Frank. “Here, both of you plant a foot alongside mine, and in that way we’ll have a set of prints to go by. Now notice just what they look like, and see if you can find any fresh marks that are different in some way from ours.”

It was an easy task he had set them, for almost immediately Billy sang out to the effect that he had made a discovery, and hardly had he ceased speaking when Pudge announced that he, too, wanted Frank’s opinion on a footprint that was much too large to have been made by any of them.

A further hunt revealed the fact that apparently three parties must have been at the foot of the steps leading up to their locked hangar. This important discovery was anything but pleasant to Frank Chester; it told him that a crisis was undoubtedly approaching their enterprise, which would seriously affect its success or failure.

What if, after all their earnest work, just when the wonderful seaplane had been made ready for a flight, those secret emissaries of the Germans managed to steal it away! Doubtless they had prepared for just such a stroke, and had an experienced air pilot hovering around so as to take charge of the hydro-aëroplane after it was successfully launched.

That would be the last the aëroplane boys would ever see of their valuable property. In time of war all devices are recognized as proper, and this theft of the American seaplane would be hailed as one of the most glorious feats of the German arms, as well as a serious blow at the air power of the Allies.

“There’s only one thing to be done,” said Frank, turning to the stout chum, “if you are game to tackle it, Pudge.”

The fat boy winced but set his teeth hard together.

“Rifles and rattlesnakes, just try me, Frank, that’s all!” he chortled, squaring his shoulders aggressively in a manner the others both knew meant that his fighting blood had been aroused.

“While Billy and I stay here to guard the machine, you must go back to town and get another kind of padlock, Pudge!” exclaimed Frank. “Pick out one that will hold as securely as this does. If we have to change it every day, we’ve got to make a sure thing of it.”

“Was it that you said you meant to speak about after we got inside the hangar, Frank?” inquired Billy as Pudge prepared to start bravely away through the gathering shadows of evening.

“Well, it was something along the same lines,” explained Frank; “in fact, I meant to suggest that one of us stay here nights until we had word from Headquarters that the hour had come to make our test, and prove that the Sea Eagle could stand up against a gale when common seaplanes would go to smash, or have to stay at their moorings.”

“Mumps and mathematics, but I agree with you there, Frank!” cried Pudge. “And for one I’m in favor of camping out here right along. We could rig up a little stove, and cook our meals. It would be good fun at that, because then we’d have the real old-fashioned Yankee grub instead of this French fool stuff that never satisfies a healthy appetite.”

The others looked at Pudge and exchanged nods. They knew his failing, and could sympathize with the poor fellow. Pudge was patriotic enough to prefer the American style of cooking, which always spelled abundance according to his way of thinking.

“I’m off, fellows,” he now announced. “Look for me inside of an hour or so. Of course, it’ll be about dark by then, but I know every stone on the road between here and town, I’ve traveled along the way so often. So long!”

With a genial wave of his hand, Pudge left them. The other pair looked after him with considerable solicitude; there was only one Pudge after all, according to their opinion, and he had a happy faculty for wrapping himself in the affections of his mates.

“You don’t think anything could happen to him going or coming, do you, Frank?” asked Billy Barnes, as they saw Pudge vanish through the partly open gate of the high stockade.

“Why, no; I hardly think so,” replied the other slowly. “Perhaps I should have gone for the padlock myself. If I had thought twice, I would have done that.”

“Too late—Pudge is on the way,” remarked Billy. “Let’s go up and take a peep around once more to see that everything is in apple-pie shape—each wire-stay keyed up to the right tune for efficiency, the motors ready to do business, the gas pump lubricated, and, in fact, our machine fit to toe the scratch as if there were a race on.”

Once they were inside the hangar, Frank fastened the door with a bar that had been arranged for just such a purpose. Then, turning on a flood of light from an acetylene gas battery, they examined every part of the big seaplane. It had something of the appearance of a gigantic sleeping bat as it lay there motionless, but with all the attributes of tremendous power for skimming along on the surface of the water or soaring among the clouds.

“In perfect condition, as far as I can make out!” remarked Frank, after they had completed this careful survey.

“Yes,” added the other, with a glow of excusable enthusiasm on his face, “and if there was any necessity for doing it we could be off with a minute’s notice.”

“I took pains to make sure that there was a clear and uninterrupted stretch of water in front of our hangar,” said Frank. “No vessels are allowed to anchor on this side of the harbor, though there are many transports from Great Britain across the way that have brought men and war material and stores over.”

“Oughtn’t Pudge be about due by now, Frank? It’s pitch dark outside, and I should think a full hour must have crept by since he left us?”

“I was thinking of that myself, Billy. Still, we must remember that our chum is a bit slow on his legs, compared with the way you and I get over the ground. Besides, he may have been delayed at the store where he expects to get the new padlock.”

“Yes, I hadn’t thought of that,” admitted Billy. “But we might use the ’phone we have installed, and find out if he’s started back. It would make our minds a little more easy, you know.”

“Just as you say, Billy. And suppose you call them up while I do something I want to alter here—nothing of consequence, of course, but the change would strike my eye better.”

“All right, Frank.” With which remark Billy turned to one end of the hangar close by, where a telephone apparatus could be seen attached to the wooden wall.

Frank went at his little task with his customary vim. It mattered nothing to him that the flight of the great seaplane would be neither hindered nor assisted by its consummation. He simply liked to see things shipshape at all times.

“What’s the matter, Billy?” he called out presently, on hearing the other ring for the third time, and also muttering to himself as though annoyed.

“Why, Frank, I don’t seem able to get Central,” replied Billy, once more energetically working the handle of the apparatus.

Apparently Frank was enough interested to cross over so as to see for himself what was wrong. He sat down on the box Billy vacated and tried to get in touch with the operator at the central switchboard. After testing it in several ways, Frank replaced the receiver and looked up at his chum.

“Have they disconnected our wire at Central, do you think, Frank; or is the hello girl flirting with her beau, and not paying attention to business?” asked Billy.

“Neither,” answered the other soberly; “but I’m afraid somebody has cut our wire so as to keep us from calling for help if anything happens here to-night!”

CHAPTER III.
 
SAVING THE GREAT SEAPLANE.

“Gee whillikins! that sounds like a serious proposition, Frank!” exclaimed Billy Barnes, when he heard the opinion of his companion.

“It looks as though we’re up against something,” admitted the other grimly. “They’ve evidently set out to capture this seaplane, and mean to do it, no matter at what cost.”

“A compliment from the Kaiser to the ingenuity of Yankee inventors, I’d call it,” said Billy; “but all the same I don’t feel like throwing up my hands and letting them raid our shop here. It’s a good thing we made that discovery, thanks to Pudge and his sharp eyes.”

“Yes, and that you thought to use the wire, which showed us how somebody had been meddling so as to cut us off from the city,” Frank remarked.

“What if they come in force, knowing we’re here, Frank?”

“That door would not be able to stand much of an attack if they carried axes along with them, I’m afraid,” Billy was told.

“My stars! do you think they’d be apt to do that sort of thing?” demanded the astonished assistant, as he looked around for some sort of weapon with which he might defend the passage of the doorway, should it come to a question of fighting.

“If they want this plane as badly as we think they do,” said Frank, “there is little that desperate men might attempt that they would not try.”

“And still there’s no sign of poor Pudge!” ventured Billy, putting considerable emphasis on the adjective, as though he could almost imagine the happy-go-lucky Pudge lying on his back somewhere along the road, groaning in pain after having been struck down by a cowardly blow.

“I’m sorry to agree with you,” Frank admitted slowly, “but at the worst we’ll hope they’re only detaining our chum, and that he hasn’t been hurt.”

“How about my slipping out and trying to go for help, Frank? If they only knew at Headquarters about this, they would send a whole regiment of British Tommies on the run to patrol our works here. Say the word and I’m off.”

Frank, however, shook his head as though the idea did not appeal to him.

“The chances are they would be on the lookout for something like that, Billy.”

“And lay for me, you mean, don’t you, Frank? Well, then, if it wasn’t so cold I’d propose slipping down to the water and doing a little swimming stunt. Too bad we didn’t think to have a boat of some kind with us.”

“I was just thinking,” ventured Frank, “that only on account of our being rushed for time we would have installed a wireless plant here, as we’ve often done before. Then we could send all the messages we wanted, and these spies wouldn’t be able to bother with them.”

“Yes, if we had only thought we’d run against a snag like this, Frank, we could have done that as easy as falling off a log. But it’s too late now to bother. The question is, what can we do about it?”

“There’s always one last resort that I know of, Billy.”

“Glad to know it, but please inform me as to its nature, won’t you, Frank? I would give half of my year’s salary just to be able to snap my fingers in the faces of these smart secret agents of the envious Germans who want to steal our thunder.”

Frank turned and pointed straight at the big seaplane.

“There’s the answer, Billy!” he said shortly.

At first the other simply stared as though unable to grasp the meaning of Frank’s words. Then a sudden gleam of gathering intelligence began to show itself in his eyes; he emphatically brought down his fist in the open palm of his other hand.

“Wow! that’s sure the ticket, Frank!” he burst out with, his enthusiasm spreading until his face was one solid grin. “We’ve got a way of escape right in our grip, and I was so blind as not to see it. Run off in the plane, of course, and leave the smarties to bite their fingernails. Great head, Frank! These German spies may think themselves wide-awake, but they’ll have to get up bright and early in the morning to catch two Yankee boys napping, believe me!”

“Listen, Billy!”

“Did you think you heard something then, Frank?”

“There’s someone at the door yonder; I saw it move, but the bar kept it from giving way,” Frank went on in a low tone. “Don’t act as though you suspected anything out of the way. They may be watching us through some peep-holes that have been bored in the walls. It would be foolish for us to give our plan away.”

“I understand what you are aiming at, Frank,” remarked the other, trying hard to appear perfectly natural, immediately adding under his breath: “There, I saw the door quiver again. They must wonder why it refuses to give way. That bar is our salvation, because like as not there’s a number of them out there who would flock in with all sorts of weapons, meaning to keep us quiet while their aviators examine the machine and get ready for a launching. Whee! then good-by to our bully Sea Eagle forever.”

“That’ll never happen as long as we can lift a hand to prevent it,” said Frank.

“Say, you don’t think that could be Pudge trying the door?” suggested Billy, as though struck by a sudden bright idea.

“Not very likely,” came the reply; “but we can easily tell. If he hears me give our old signal, Pudge will answer on the dot. Listen and see if anything comes of it.”

The whistle Frank emitted was of a peculiar character. It was immediately imitated from without, and so exactly that one might think it an echo. Frank shook his head on hearing this.

“Pudge isn’t there,” he said decisively. “If he was, as you very well know, Billy, he would have sent back the other call, entirely different from the one I gave.”

“Then some fellow answered for Pudge, thinking we might open up, when they could rush the place and get possession—is that the way it stands, Frank?”
