He turned round, intending to get up immediately; yet, yielding to the impulse of wearied nature, he again slumbered.

Once he thought that he heard a footstep, roused himself, and listened; but all was quiet and still, except the light wave rippling on the sand.

Again he was roused by a sort of grating noise; he listened, and all was quiet.

A third time he was roused by a sound like the flapping of a sail: he listened--he was sure of it, and he sprang upon his feet.

It was dawn of day, and as he turned his eyes towards the beach, he perceived to his horror that the boat was indeed under sail, Jackson, who was in it, then just hauling aft the main-sheet, and steering away from the island.
