Frank’s navigating instruments found their place in a pocket handy to the steersman’s hand. The compass of course being adjusted in a balanced socket that kept it always visible to the helmsman. The operating keys of the Golden Eagle II’s wireless apparatus were in the rear of the chassis and in the space beneath its stand was coiled the five hundred feet of rope through which ran a strand of phosphor bronze wire which was to be used for grounding the current. Alongside the reserve gasolene found its place.

The searchlight, swinging easily on a pivot, was also of course a part of the helmsman’s equipment, and handy to him was slung his revolver in a big loose holster. The rifles and ammunition and the stock of provisions carried went in the lockers, as well as a waterproof sod-cloth to place beneath the chassis if camping on wet ground, and a small blue-flame oil-stove made of aluminum. The few cooking utensils carried were also of aluminum and nested. The last thing to go aboard was a folding canvas boat of which more later.

All these preparations concluded, the boys partook of the last dinner they were to eat in company for perhaps several days. Over the meal, which Pork Chops had made quite an elaborate one in celebration of the occasion, final plans were discussed. Lathrop was to have charge of the wireless apparatus and at all hours of the day or night either he, Ben Stubbs or Billy Barnes was to be on duty beside it on the watch for calls. The boys would also, it was agreed, watch their apparatus constantly. Frank’s ingenuity had provided each machine with an appliance, not unlike the ordinary telephone bell, which commenced ringing loudly as soon as any other instrument within range got “in tune.” This was a patentable improvement, as an ordinary wireless machine has no such convenient attachment and only apprises its operator of a call by a faint click hardly audible to the unpracticed ear.

After lunch the boys went over every rod and wire of the aeroplane and found her to be in first class shape. While these preparations were going on Quatty had been eyeing the craft with the liveliest indications of fear.

“Ah’d jes’ as soon ride on de back ob a fish eagle,” he said apprehensively.

“Why, Quatty, you’re not going to back out now, are you?” asked Frank with a smile at the negro’s trepidation.

“Lord, no, Massa Frank, ah said ah’d go wid yo’ an’ I will, but ef it wasn’ fo’ dat rifle I wouldn’ go not fo’ nuffin’. Say,” he added suddenly, “could ye jes’ wait a while till I paddle home an’ say goo’-bye to my wife?”

“No, we can’t,” laughed Frank, ruthlessly cutting short the black’s hope of even a moment’s reprieve from going aloft in the object of his terror.

“Are we all ready, Harry?” he asked the next minute.

The younger boy nodded.
