“Huh! that crate’s startin’ off again, seems like,” he muttered.

Indeed, it was a foregone certainty for the splash of water told the story as well as the abrupt explosions of a working motor. Then, too, these suggestive sounds all came from directly ahead.

Then Perk had another gripping fear which he imagined must have also seized his companion–that the chief object of their concern might be a passenger aboard that ship, heading once more across the state to Miami and that in consequence, all of Jack’s carefully laid plans would meet the same untimely fate as befalls an ambitious soap-bubble when struck by a stray puff of air.

So they continued to stand there and listen to the telltale sounds with sinking hearts. Perk in particular seemed to be dreadfully put out by this fresh upset and was grinding his strong teeth as though desirous of letting out an explosive but restrained by the fact of Jack being so close at hand.

“Gee whiz! this here is what I call tough luck, Boss,” he grumbled, more because he hoped Jack might be able to dispel his fit of the blues in some way or other, having a much clearer vision than he himself possessed.

“Oh! I don’t know, partner,” said Jack in a wholesome, optimistic tone. “It looks a little dark, but just wait a minute or so before you croak–after all, the thing may not be so bad–it doesn’t pay to jump at conclusions.”

“Shucks! that’s me all over, old hoss, but I’m sure glad to hear you say the last chance ain’t snuffed out yet,” mumbled Perk contritely, but at least he had gained his point which was to coax Jack to mix a little good cheer in with the gloom that had descended on his, Perk’s soul.

“There, he’s off!” declared Jack as a significant change in the clatter so thoroughly understood by any airman announced the hop-off from the surface of the lake.

“An’ nothin’ happened to give him a spill, either,” Perk went on to say and the disconsolate vein in his tone told plainly enough how he had been secretly hugging to his heart a hope that the motor of the Lockheed-Vega crate might suddenly develop some fault, compelling the flight to be abandoned in its inception.

“Even that fact may yet turn out to be the best thing we could wish for,” Jack told him confidently, being built on the order of a fellow who could see something to rejoice over in nearly every occurrence, no matter how thick the gloom surrounding it.
