It might indeed be a rock. He had passed one shortly before, which had gradually declined into the bottom of the sea; this might be a continuation of the same, which after an interval had arisen again from the bottom. It was long and high at one end, and rounded forward at the other. Such a shape was perfectly natural for a rock. He tried to crush down hope, so as to be prepared for disappointment. He tried to convince himself that it must be a rock, and could by no possibility be any thing else. Yet his efforts were totally fruitless. Still the conviction remained that it was a ship, and if so, it could be no other than the one he sought. As he went on all the marine vegetation ceased. The coral rocks continued no further. Now all around the bottom of the sea was flat, and covered with fine gravel, like that which he had touched when he first came down. The fishes had departed. The sense of solemnity left him; only one thing was perceptible, and that was the object toward which he walked. And now he felt within him such an uncontrollable impulse that even if he had wished he could neither have paused nor gone back. To go forward was only possible. It seemed to him as though some external influence had penetrated his body, and forced him to move. Again, as once before, he recalled the last words of his father, so well remembered: --“If in that other world to which I am going the disembodied spirit can assist man, then be sure, oh my son, I will assist you, and in the crisis of your fate I will be near, if it is only to communicate to your spirit what you ought to do--” It was Ralph Brandon who had said this. Here in this object which lay before him, if it were indeed the ship, he imagined the spirit of another Ralph Brandon present, awaiting him. Suddenly a dark shadow passed over his head, which forced him involuntarily to look up. In spite of his excitement a shudder passed through him. Far overhead, at the surface of the sea the boat was floating. But half-way up were three dark objects moving slowly and lazily along. They were sharks. To him, in his loneliness and weakness, nothing ever seemed so menacing as these three demons of the deep as he stared up at them. Had they seen him? that was now his thought. He clutched his knife in a firmer hold, feeling all the while how utterly helpless he was, and shrinking away into himself from the terror above. The monsters moved leisurely about, at one time grazing the tube, and sending down a vibration which thrilled like an electric shock through him. For a moment he thought that they were malignantly tormenting him, and had done this on purpose in order to send down to him a message of his fate. He waited. The time seemed endless. Yet at last the end came. The sharks could not have seen him, for they gradually moved away until they were out of sight.
