Returning to the ledges of rock, he walked about among them, and found a number of pools, some of which were of considerable size. These had been left by the retreating water; and in these hollows he soon saw a number of small objects moving about. Some of them he caught without much difficulty, and saw that they were shrimps. He had hoped to find some of these, but the discovery came to him like some unexpected pleasure, and seemed more than he had any right to count on. Beside the shrimps his other discoveries seemed inferior. There was a large number, and they could be caught without much trouble. He soon filled his pan, and brought these also to his camping-place. These he deposited in a little pool, which was on the surface of some rocks that lay not far from the shore. Over these he also laid some sea-weed. The tide was now coming up, but Tom made a further journey to the beach, so as to secure something which he had noticed during his previous expedition. This was a marine plant called dulse, which, in these waters, grows very plentifully, and is gathered and dried by the people in large quantities. It was a substance of which Tom was very fond, and he determined to gather some, and dry it in the sun. Collecting an armful of this, he took it to the shore, and spread it out over the grass, though, in that damp and foggy atmosphere, there was not much prospect of its drying. It was now about three o'clock in the afternoon, and Tom's researches along the shore were successfully terminated. He had found all the different articles that he had thought of and his new acquisitions were now lying about him. These were,-- Clams, Lobsters, Mussels, Shrimps, Dulse. As he murmured to himself the list of things, he smiled triumphantly. But still there was work to be done. Tom intended to keep fashionable hours, and dine late, with only a lunch in the middle of the day. His explorations of the afternoon were to be important, and he hoped that they would be crowned with a portion of that success which had attended the work of the morning. He took, therefore, a hasty lunch of biscuit and cold lobster, washed down with water, and then set forth. This time he turned away from the shore, and went to the top of the island. He carried in his hand a bit of rope, about a dozen feet in length, and went along the edge of the cliff as far as he could, turning aside at times to avoid any clumps of trees or bushes that grew too thickly. In front of him the line of cliff extended for some distance, and he walked along, until, at last, he came to a place where the gulls flew about in larger flocks than usual, almost on a line with the top of the rock. He had not noticed them particularly on his former walk along here; but now he watched them very attentively, and finally stood still, so as to see their actions to better advantage.
