THE MIDNIGHT BELL.

It required considerable persuasion on the part of Frank and Harry to induce Mr. Chester to allow them to undertake a trip which, to say the least, was hazardous. After a long talk, however, it was agreed that the boys were to be allowed to go providing that if they did not return within the next three days they were to use every effort to notify their father of their whereabouts.

All opposition being overcome, the boys, after a hearty meal, made a change into light woolen shirts, khaki trousers and rubber-soled canvas shoes. Soft felt hats of the army type completed their attire, and when they had each buckled on a belt to which were strapped magazine revolvers and slung field-glasses and water-padded canteens over their shoulders they were practically ready for their bold dash.

Frank at once made a hasty survey of the ground surrounding the palm-thatched aerodrome and decided that with a little clearing the Golden Eagle could be started without any difficulty if no wind got up. A force of men was at once put to work with machetes and long before noon a “runway” of five hundred yards leading downhill had been cleared,—Frank calculating that this would be sufficient to allow the aeroplane to lift and clear the taller banana bushes. The gasolene for the sixty-gallon tank had been shipped from Greytown at the time that Frank and Harry tuned up the Golden Eagle’s engine, and besides filling the tank to its capacity they loaded their craft up with several five-gallon cans for a reserve supply. A stock of the best cylinder oil and grease for the “screw-up” grease cups that lubricated the crank shafts completed the engine outfit.

The boys calculated on using a pint per horsepower an hour of fuel when the Golden Eagle’s engine was running at its greatest number of revolutions per minute. As they did not intend to turn up more than 800 revolutions—or R.P.M., as aviators call it—they calculated on a considerable saving of fuel unless some emergency arose.

While the runway was being cleared, several of the native workmen had been at work, under the boys’ direction, hauling away the ballast sacks with which the Golden Eagle had been weighed down at the time of her engine test. Harry had also produced a brand-new ensign which he ran up on halyards rigged to a stern stanchion, while his brother and father gave three hearty cheers for the fluttering Stars and Stripes.

The last thing the boys did before their final farewells was to tuck a map of the country over which they were to travel in a corner pocket of the pilot-house, and also load up a waterproof silk tent and an axe, shovel and pick.

“It’s always as well to be prepared for everything,” Frank remarked when his father questioned him about the utility of these last articles. “We don’t know but we may have to dig for water or—or anything in fact in which these tools will come in mighty handy.”

Mr. Chester nodded admiringly at his son’s foresight.

“That’s right, my boy,” he assented, “be ready for everything and you can’t go far wrong.”
