“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.
