The following morning Helen was surprised to see the boat riding at anchor in the surf, and Hazel busily engaged on her trim. He was soon on shore, and by her side. "I am afraid I must leave you for a day, Miss Rolleston," he said. "I wish to make a circuit of the island; indeed I ought to have done so many days ago." "Is such an expedition necessary? Surely you have had enough of the sea." "It is very necessary. You have urged me to undertake this enterprise. You see, it is the first step toward announcing to all passing vessels our presence in this place. I have commenced operations already. See on yonder bluff, which I have called Telegraph Point, I have mounted the boat's ensign, and now it floats from the top of the tree beside the bonfire. I carried it there at sunrise. Do you see that pole I have shipped on board the boat? That is intended as a signal, which shall be exhibited on your great palm-tree. The flag will then stand for a signal on the northern coast, and the palm-tree, thus accoutered, will serve for a similar purpose on the western extremity of the island. As I pass along the southern and eastern shores, I propose to select spots where some mark can be erected, such as may be visible to ships at sea." "But will they remark such signals?" "Be assured they will, if they come within sight of the place." Hazel knew that there was little chance of such an event; but it was something not to be neglected. He also explained that it was necessary he should arrive at a knowledge of the island, the character of its shores; and from the sea he could rapidly obtain a plan of the place, ascertain what small rivers there might be, and, indeed, see much of its interior; for he judged it to be not more than ten miles in length, and scarce three in width. Helen felt rather disappointed that no trace of the emotion he displayed on the previous night remained in his manner or in the expression of his face. She bowed her permission to him rather haughtily, and sat down to breakfast on some baked yams, and some rough oysters, which he had raked up from the bay while bathing that morning. The young man had regained an elasticity of hearing, an independence of tone, to which she was not at all accustomed; his manners were always soft and deferential; but his expression was more firm, and she felt that the reins had been gently removed from her possession, and there was a will to guide her which she was bound to acknowledge and obey. She did not argue in this wise, for it is not human to reason and to feel at the same moment. She felt then instinctively that the man was quietly asserting his superiority, and the child pouted.
