The next thing to decide about was the choice of a place. There was the east end, and the west end--which was the better? The west end, where he was standing, was high; but then it was surrounded by trees, and unless he could set up a very tall staff, it could scarcely be noticed. The east end, on the contrary, was lower; but then it was bare, and any kind of a signal which might be set up there could hardly fail to attract attention. He could also pile up a heap of drift-wood, and set fire to it, and, by this means, if a vessel were passing by, he could be certain of securing attention. It did not make much difference which end the signals were placed upon, as far as referred to the passing of vessels; for all that passed by would go along the island, so that both ends would be visible to them. As to the signals, he felt confident that he could find a staff, or, if one would not be long enough, several could be fastened together. The coil of rope in the boat would enable him to do this. The sail would afford material for a flag. All these plans came to his mind as he stood there; and the prospect of once more doing something which was to help him to escape from his prison drove away the last vestige of his grief. His courage again arose, hope revived, and he burst forth into a light and joyous song. Very different was he now from the despairing lad who, but a short time before, had been pouring forth his tears of sorrow; and yet but a few minutes had passed since then. The steamer was yet in sight down the bay, but Tom, who had lately been so frantic in his efforts to attract her attention, now cast a glance after her of perfect indifference. And now it was necessary for him to return to the east end of the island, and look about for the means of putting into execution his plan for making a signal. He started off on his return without any further delay. The path back was as rough and toilsome as the way down had been; but Tom was now full of hope, and his elastic spirits had revived so thoroughly that he cared but little for the fatigue of the journey. It was traversed at last, and he descended the slope to the place from which he had started. His exploration of the island had been quite complete. It seemed to him to be about a mile and a half in length, and a half a mile or so in width. The east end, where he had first arrived, was the only place where it was at all desirable to stay. Immediately on his arrival he examined the boat, and found it secure. To his surprise it was now about sunset. He had forgotten the lapse of time. He was hungry; so he sat down, ate his biscuit, drank his water, and rested from the toils of the day. XVI.
