Nevertheless, since there was always a fair chance that the secreted sloop might escape discovery, Perk finally concluded to dispose of his own person, at the same time meaning to keep in readiness to give the intruders a hot reception, did the occasion warrant such a course.

Then he could hear what he knew to be the splash of oars, and squeaking sounds of the row-locks. But he had already discounted this fact, knowing as he did the impossibility of anyone ever reaching the fringe of that vast wilderness of mangrove islands in which many a fisherman had been lost, never to find his way out of the myriad of zigzag channels without the possession of some manner of boat.

On they came until finally Perk realized they were just around the corner, for he could pick up every word that was uttered as well as see specks of foam from the working oars as it carried past, the tide being on the ebb just then.

“Told yuh it was a steamer runnin’ past thet sent up yer smoke trail, Zeb,” a harsh jeering voice was saying, accompanying the words with a string of oaths as though he felt more or less “mad” because of the exertion necessitated in working at the oars so long and on a bootless errand at that.

“Wall,” came another drawling voice in which keen disappointment could be detected. “I judged it shore lay in this direction, but like yuh says, it must’a ben a steamer out yonder on the gulf–mebbe thet rev’nue boat they done tole us to watch out fur er else some o’ them spongers frum up Tarpon Springs way. Anyhow, I got all I wants o’ exercise so I move weuns call hit a day an’ get back to the shanty.”

“Yas, thet’s the best thing we kin do,” agreed the other, with a snarl in his heavy voice, “we got heaps o’ work ahead tonight, if so be thet Fritz airpilot does drop over with his batch o’ yeller boys like weuns been told he’d do. I’d like tuh see the whole caboodle o’ Chinks dropped inter the middle o’ the gulf, I hate ’em so, but thar’s good money in the game, we happens tuh know, Zeb, which I jest caint hold back on nowhow. Les go!”

Greatly to the relief of the listening Perk he heard the sound of splashing gradually recede until finally it died away completely. This gave him a feeling bordering on relief, for while Perk was an old hand at the fighting game and stood ready to give a good account of his ability to defend their prize; at the same time he had no violent desire to open up on the two occupants of the unseen rowboat nor yet was the idea of the sloop being discovered at all to his taste.

“Lucky lads you might count yourselves if on’y you knew how I was layin’ right here in ambush, ready to sink that boat an’ make the biggest sort o’ a splash. An’ I’m guessin’ I got off right smart ’bout that cookin’ fire racket, come to think of it–might a’spilled the beans all right, and made all sort o’ trouble for our crowd.”

Talking in this fashion to himself, Perk again set about taking things comfortably nor did he ever hear of that pair again. Still, he treasured up in his mind what he had heard the man with the harsh voice say in connection with the smuggling of unwelcome Chinese immigrants who were ready to pay so well for an opportunity to beat the Government regulations in their eagerness to join the foreign colony in Mott Street, New York City, where the vast majority of them were bound. It would naturally interest Jack when he heard the news, although it could hardly be considered startling, since they already knew full well this sort of thing was being carried on by daring airplane pilots in the service of the far-flung smuggling combine.

By now it was well past the middle of the afternoon. Light fleecy, white clouds had been drifting up from the direction of the Dry Tortugas and Key West but this far they did not look at all portentous, as though any kind of a storm might be brewing. Perk hoped that would not turn out to be the case since they had work planned for a part of the coming night, which would be greatly hampered by unsettled weather.
