“Oh, when the moon shows up will be plenty of time,” came the ready answer. “Our objective isn’t so very far distant and you know we can make a hundred miles an hour if necessary. I’d like to pick up a bit of my lost sleep while we wait, unless you object to standing sentry.”

“Not me, matey, I managed to snooze some during the time you were away. Lucky I had everything fixed for company and wasn’t caught nappin’ when our friend Oscar tipped his hat an’ made his bow. Now I was wonderin’ if he had that ole quick-firin’ gun away back when he was riddlin’ things along in the Argonne–wouldn’t it be a queer thing if true? He knew how to rattle that cantankerous bus to beat the band an’ he did nick me in that silly o’ ear o’ mine that keeps on gettin’ in the way every time I have a little spat with a sassy guy.”

Perk insisted on his chum making himself as comfortable as possible, considering the cramped quarters they occupied in the cluttered cabin of their ship, which continued to keep up a soothing movement with the successive waves that worked in from the open gulf inclining a sleepy person to slumber.

“I’ll jest sit here an’ ruminate while I consume my tobacco,” announced the accommodating Perk, making light of his job. “Once in so often I’ll take a look skyward with the glasses, so’s to know if there’s any chance o’ Oscar comin’ back here to try it all over again. When the moon peeps up in the east yonder I’ll put a hand on your arm, so’s to let you know it’s near time. Go to it, partner–do your stuff.”

Jack was feeling pretty tired, since he had enjoyed mighty little decent sleep from one cause or another during the last few nights. It was not at all surprising, therefore, that he should be in slumberland before five minutes passed after he and Perk had exchanged the last word.

The self-posted sentinel did just as he had promised, every little while he would quietly stand up and with the glasses take a keen observation, covering the blue vault above from one horizon to another, then, finding all serene, he would silently resume his seat, with only a sigh to indicate how he felt. Once more he filled his everlasting pipe, began to puff delightedly, and finally lay back in a half reclining position to smoke it out.

He was a great hand at ruminating, as he called it–allowing his thoughts to travel back to events that may have occurred months, and even years before, but which had been of such a nature as to fix themselves in his memory most tenaciously. This afforded him solid enjoyment, together with the charm of his adored pipe and he asked for nothing better.

Thus an hour, two of them, and more passed, with nothing out-of-the-way taking place to attract his attention. He figured that if the pilot of the Curtiss-Robin crate intended to come back that night, he was subject to some sort of delay.

There was frequent splashing in the lagoon near by–at times Perk could tell it must be caused by jumping mullet, but on other occasions the sound being many times exaggerated, he reckoned it had been made by an alligator plunging off a log into the water, either alarmed by some sound further off, or else possessed of a desire to enter a secret underwater den he laid claim to. This would probably have a second entrance, or exit, up on some hummock that Perk had failed to discover when poking around on the preceding day hunting green stuff with which to conceal the deck of the sloop.

Suddenly Perk noticed a slim streak of pale light fall athwart the propeller blade just before him and looking hastily up discovered the smiling face of the moon–a bit battered it is true, for the silvery queen of night was just then on the wane.
