Now, when they came to figure upon it later on, the motor boat chums were of the opinion that even under such adverse conditions they could not have been more than six or seven minutes in passing through the wooded center of the island. It was only a small affair at best, and by daylight could have been crossed in much less time. And yet there was Buster, for instance, who must have been laboring under the impression that fully half an hour had already passed since they first started to break into the thick growth, and butt up against all these crazy obstacles—the logs that would get under a fellow’s feet, the encircling loops of dangling wild grape-vines; the trees that bobbed up most unexpectedly, and tried to knock one’s brains out, and a lot of other things along the same line “too numerous to mention.”

Of course none of them gave much heed to what their conduct would be when they managed to overtake the enemy.

That would have to be left pretty much to accident. Perhaps some of the boys, under the belief that they must present quite a hostile appearance, with all sorts of clubs and cudgels in evidence, not to speak of that gun Jack carried, fancied that the two burglars would take to flight at sight of the advancing legion. But Jack, and perhaps Herb also, did not delude themselves with this expectation; for they could remember just how that fellow aboard the stolen boat had warned Jenks off, and even wounded him in the arm when he refused to stop short.

They set him down as a dangerous character, which he undoubtedly must have been, to have carried out the bold programme connected with the looting of the up-river bank.

At any rate, they must be getting close to the other side of the island now, for there was a perceptible slope downward, and this must mean the crest had been left behind.

Yes, and sure enough, the trees were getting less dense, though the brush might be as thick as ever. Jack hoped for one thing that luck would favor them, and allow of their breaking out upon the little beach at just the exact spot where the two men were working.

At the same time he did not feel any too sanguine of success, for which there were numerous reasons. Surely the two thieves must be aware of the fact that the pack was pushing toward them, for there was plenty of noise accompanying their forward progress.

And knowing this, would it not be the easiest thing for them to gauge their time of flitting by the closeness of the coming host? Jack thought so, even while still exerting himself to the uttermost in order to get to the shore as speedily as possible.

Ah! now he could see more light ahead, which told in so many words that they must be close to the river again. Their troubles were behind them now; that is, insofar as they concerned navigating the dense jungle that covered the island of the bad name.

Those still ahead would be of an entirely different nature, and might consist of running up against the desperate thieves.
