“I’ve got yer at last.”

Bob sprang up as if electrified, saw who spoke, and was about to burst into a torrent of angry abuse, when he followed the direction of Dexter’s pointing hand, caught the approaching danger, and seized an oar.

It was none too soon, for as Dexter seized the other, the man evidently realised that his prey was about to make another effort to escape, and, bending to his work, he sent the little tub-like boat surging through the water.

“Pull, Bob!” said Dexter excitedly, an unnecessary order, for Bob had set his teeth, and, with his face working, was tugging so hard that it needed all Dexter’s efforts to keep the boat from being pulled into the right-hand shore.

The chase had begun in full earnest, and for the next hour, with very little alteration in their positions, it kept on. Then the pace began to tell on the boys. They had for some time been growing slower in their strokes, and they were not pulled so well home. Bob engaged every now and then in a dismal, despairing howl, usually just at the moment when Dexter thrust his oar too deeply in the water, and had hard work to get it out.

But their natural exhaustion was not of such grave consequence as might have been imagined, for their pursuer was growing weary too, and his efforts were greatly wanting in the spirit he displayed at first. On the other hand, though the man came on slowly, he rowed with a steady, stubborn determination, which looked likely to last all the morning, and boded ill for those of whom he was in chase.

Bob’s face was a study, but Dexter’s back was toward him, and he could not study it. The enemy was about two hundred yards behind, and whenever he seemed to flag a little Bob’s face brightened; but so sure as the man glanced over his shoulder, and began to pull harder, the aspect of misery, dread, and pitiable helplessness Bob displayed was ludicrous; and at such times he glanced to right and left to see which was the nearest way to the shore.

As Bob rowed he softly pushed off his boots. Soon after he made three or four hard tugs at his oar, and then, by a quick movement, drew one arm out of his jacket. Then rowing with one hand he shook himself quite clear of the garment, so as to be unencumbered when he began to swim, for that was his intention as soon as the man overtook them, and his peril became great.

“He wants most of all to get the boat,” he thought to himself; and soon after he opened his heart to Dexter.

“Lookye here!” he said, “he wants to get the boat; and if he can get that he won’t come after us. Let’s row pretty close to the bank, and get ashore and run.”
