The Boy Aviators on Secret Service; Or, Working with Wireless

“What an impetuous chap you are,” laughed Frank, “we don’t start for three weeks yet and here you are in a hurry to throw up your job to-day.”

“Well,” replied Billy somewhat abashed, “I was a bit previous. But it’s so white of you chaps to take me along that I hardly know what I’m doing. How I’m to wait three weeks I don’t know.”

“How would you like to help us build the Golden Eagle II?” asked Frank suddenly.

“Say, Frank,” burst out Billy earnestly, “you are a trump. That was just the very thing I longed to do but I didn’t have the nerve to ask you after you were so decent about taking me with you to Florida. I don’t know how to thank you.”

“It won’t be all a picnic,” laughed Frank. “We’ve got a lot of hard work ahead of us and we’ll all have to pitch in and take a hand, share and share alike.”

“You can count on me,” exclaimed the reporter eagerly.

“I know we can,” replied Frank, “or we would not have asked you to accompany us.”

“What are your plans?” asked Billy eagerly.

“At present so far as I have thought them out,” replied Frank, “we shall sail from New York for Miami about the middle of June. I think it will be best to go by steamer as we can keep a better watch on any suspicious fellow passengers in that way than if we went by train. The key on which the Mist was wrecked is on the opposite coast from there, I understand, and the men who kidnapped Chapin and stole the plans must have entered the Everglades by one of the numerous small rivers that lead back from the coast at the Ten Thousand Island Archipelago.

“My idea, then, is to establish a permanent camp from which we can work, the location of course to depend entirely on circumstances, that may arise after we reach our destination. We are going into this thing practically blindfold you see, and so we shall have to leave the arrangement of a host of minor details till we arrive there.”

“You mean to strike right back into the wilderness?” asked Billy.

“As soon as possible after our arrival at Miami,” was the businesslike rejoinder. “Every minute of our time will be precious. Oh, there’s heaps to be done,” broke off Frank.

All the boys had to laugh heartily at the wave of the hands with which Frank accompanied his last words. But their merriment was cut short by a sharp exclamation from Billy.

“I say, Frank,” whispered the young reporter, “have you noticed that fellow at the next table?” He indicated a short dark sallow-faced man sitting at a table a few feet from them and to whom most of their conversation must have been audible.

“He’s not a beauty,” remarked Harry in the same low tone; “what about him, Billy?”

“Well,” said the reporter seriously, “I may be wrong and I may not – and I rather think I’m not, – but if he hasn’t been listening with all his ears to what we’ve been saying I’m very much mistaken.”

Frank bit his lip with vexation. In their enthusiasm the youthful adventurers had been foolishly discussing their plans in tones which any one sitting near could have overheard without much difficulty. The boys realized this and also that if the man really turned out to have been an eavesdropper that they had involuntarily furnished him with much important information about their plans.

The object of their suspicion apparently saw that they had observed him, for as they resumed their talk in lowered tones he called for his bill and having paid it with a hand that flashed with diamonds, he left the dining-room.

“Have you seen him before?” asked Frank of Billy.

“I was trying to think,” replied the reporter. “It seems to me that I have. I am almost certain of it in fact. But I can’t think where.”

“Try to think,” said Frank, “it may be very important.”

Billy cudgeled his brains for a few minutes and then snapped his fingers in triumph.

“I’ve got it,” he exclaimed joyously. “I’ve seen him hanging around the Far Eastern embassy. I was up there the other day to report a reception and this fellow was wandering around as if he hadn’t got a friend in the world.”

“He might have had an object in that,” said Frank gravely. “There is no doubt that he was listening to what we were talking about.”

“And not much question that he heard every word of it,” put in Harry.

“Well, it can’t be helped,” said Frank in an annoyed tone, “we shall have to be more cautious in the future. I see that the secretary was right, this place is swarming with spies.”

“I should say it is,” replied Billy, “Washington is more full of eavesdroppers and secret-service men of various kinds than any other city in the world.”

If the boys had seen the bediamonded man hasten from the hotel direct to a Western Union telegraph office where he filed a long telegram, they would have been even more worried than they were. If in addition they had seen the contents of the message they would have been tempted, it is likely, to have abandoned the expedition or at least their present plans, for the message, which was addressed to “Mr. Job Scudder, Miami, To Be Called For,” and signed Nego, gave about as complete an account of what they intended to do as even Billy Barnes with his trained ear for catching and marshaling facts could have framed. There was a very amiable smile on Mr. Nego’s face as he left the telegraph office and drew on a pair of light chamois gloves that gave a finishing touch of fashion to his light gray spring clothes, whose every line bore evidence to the fact that they had come from one of the best tailors in Washington. He had done a good morning’s work.

The boys of course had no means of knowing that, even as they hurried to their train, the wires were rushing to Florida the news of their coming three weeks before they planned to start and even if they had been aware of it they could not then have stopped it. With Billy Barnes they dashed up to the Pennsylvania depot in a taxi-cab just as the big locomotive of the Congressional Limited was being backed up to the long train of vestibuled coaches. They had their return tickets so that there was no delay at the ticket window and they passed directly into the depot, and having found their chair car deposited themselves and their hand-baggage in it. Billy stayed chatting with them till the conductor cried “all aboard.” As the reporter rose to leave he gave a very perceptible start. He had just time to cry to Frank:

“Look behind you,” when the wheels began to revolve and Billy only avoided being carried off by making a dash for the door almost upsetting the colored porter in his haste.

As the train gathered speed Frank glanced round as if in search of somebody. He almost started, as had Billy, as his eyes encountered the direct gaze of the very black orbs of the man whom they were certain had overheard their conversation at lunch and who had signed the telegram “Nego.”

CHAPTER III

A TRAMP WITH FIELD-GLASSES

The boys lost no time in explaining to their mother when they reached their home on Madison Avenue the nature of the enterprise in which they had enlisted their services. That she was unwilling at first for them to embark on what seemed such a dangerous commission goes without saying, but after a lot of persuasion she finally yielded and gave her consent and the delighted boys set out at once for White Plains where the large aerodrome in which they had constructed the Golden Eagle I was still standing. The place was equipped with every facility for the construction of air craft and so no time was lost in preliminaries and two days of hard work saw the variadium steel framework of the Golden Eagle the Second practically complete.

The craft was to be a larger one than the Golden Eagle I, which had a wing-spread of fifty-six feet. The planes of her successor were seventy feet from tip to tip and equipped with flexible spring tips that played a very important part in assuring her stability in the air. Like the first Golden Eagle the boys had determined that the new ship, should carry wireless and the enthusiasm of Schultz and Le Blanc, their two assistants, was unbounded as Frank placed before them his working drawings and blue prints which bore on paper the craft which they expected to eclipse anything ever seen or heard of in the aerial world for speed and stability.

The old Golden Eagle had been equipped with a fifty horse-power double-opposed engine with jump spark ignition. The boys for the new craft had determined to invest in a one hundred horse-power machine of similar type and equipped with the same ignition apparatus. As in the other ship they planned to have the driving power furnished by twin screws but, whereas in the first ship the propellers had been of oiled silk on braced steel frames in the new Golden Eagle the screws were of laminated wood, razor sharp at the edges and with a high pitch.

Except for her increased size the Golden Eagle II did not differ in other respects from her predecessor. Her planes were covered with the same yellow-hued balloon silk that had given the first craft her name and the arrangement of pilot-house and navigating instruments was much the same. The boys, however, planned to give her a couple of low transoms running the length of each side of the pilot-house on which the occupants could sleep on cushions stuffed with a very light grade of vegetable wool. A light aluminum framework, which could be covered in with canvas in bad weather, or mosquito netting in the tropics, forming in the former case, – a weather-tight pilot-house with a mica window in front for the steersman, was another improved feature.

Billy Barnes was astonished when a few days later, having resigned his newspaper job, he was met at the White Plains station by Frank and Harry, and found, on his arrival at the aerodrome a framework which was rapidly beginning to assume very much the look of a real air-ship. The enthusiastic reporter crawled under it and round it and pulled it and poked it from every possible angle till old Schultz, angrily exclaimed:

“Ach, vas is dis boy crazy, hein?”

Billy was nearly crazy with joy he exclaimed and the old German’s heart warmed toward him for the interest he displayed in the craft which Schultz regarded as being as much his own creation as anyone else’s.

“Well, you certainly look like business here,” exclaimed Billy as he gazed about him. What with the lathes, the work-tables, the blue prints and plans, the shaded drop-lights and the small gasolene motor, – used to test propellers and run the machinery of the shop, – Frank and Harry were indeed as Billy said, “running a young factory.”

“You picked out a private spot,” exclaimed Billy, gazing out of the tall aerodrome doors at the low, wooded hills that surrounded them.

“Well,” laughed Frank, “if we hadn’t we’d have half the population of White Plains around here trying to get on to what we were doing and spreading all sorts of reports.”

“Oh, by the way,” asked Billy, “did you have any more manifestations from our dark-skinned friend on your way to New York?”

“No,” replied Frank, “he sat in his chair and read the papers and apparently paid no more attention to us. I really begin to think that we may have been mistaken.”

“I guess so,” said Billy lightly; “maybe he was just some rubber-neck who was surprised to hear three boys talking so glibly about invading the Everglades in an airship.”

With that the subject was dropped, for Harry, who had just entered the workshop from the small barn outside, where he had been putting the horse up, carried Billy off to show him the “camp” as the boys laughingly called it. The eating and sleeping quarters were in a small portable house, a short distance from the main aerodrome. It was divided into a dining and a sleeping room. The latter neatly furnished with three cots – a third having been added to Frank and Harry’s for Billy’s use that very morning. On its wall hung a few pictures of noted aviators, a shelf of technical books on aviation and the usual odds and ends that every boy likes to have about him. The two mechanics took their meals in the house and slept in the aerodrome. The cooking was done by Le Blanc who, like most of his countrymen, was a first-rate chef.

“Camp!” exclaimed the admiring Billy after he had been shown over the little domain, “I call it a mansion. Different from old Camp Plateau in Nicaragua, eh?”

“And you came very nearly been shaken out of even that;” put in Harry with a laugh.

“I should say so,” rejoined the reporter. “B-r-r-r-r! it makes my teeth chatter now when I think of the rain of stones that came from the Toltec ravine. By the way,” he broke off suddenly, “where is good old Ben Stubbs?”
