It is scarcely necessary to say, that when our young mate discovered the proximity of this dangerous animal, situated as he was, he gave himself up for lost. He possessed his knife, however, and had heard of the manner in which even sharks were overcome, and that too in their own element, by the skillful and resolute. At first, he was resolved to make one desperate effort for life, before he submitted to a fate as horrible as that which now menaced him; but the movements of his dangerous neighbour induced him to wait. It did not approach any nearer, but continued swimming back and fro, on the surface of the water, according to the known habits of the fish, as if watching his own movements. There being no time to be wasted, our young mate turned on his face, and began again to swim in the direction of the setting star, though nearly chilled by despair. For ten minutes longer did he struggle on, beginning to feel exhaustion, however, and always accompanied by those two dark, sharp and gliding fins. There was no difficulty in knowing the position of the animal, and Mulford’s eyes were oftener on those fins than on the beacon before him. Strange as it may appear, he actually became accustomed to the vicinity of this formidable creature, and soon felt his presence a sort of relief against the dreadful solitude of his situation. He had been told by seamen of instances, and had once witnessed a case himself, in which a shark had attended a swimming man for a long distance, either forbearing to do him harm, from repletion, or influenced by that awe which nature has instilled into all of the inferior, for the highest animal of the creation. He began to think that he was thus favored, and really regarded the shark as a friendly neighbor, rather than as a voracious foe. In this manner did the two proceed, nearly another third of a mile, the fins sometimes in sight ahead, gliding hither and thither, and sometimes out of view behind the swimmer, leaving him in dreadful doubts as to the movements of the fish, when Mulford suddenly felt something hard hit his foot. Believing it to be the shark, dipping for his prey, a slight exclamation escaped him. At the next instant both feet hit the unknown substance again, and he stood erect, the water no higher than his waist! Quick, and comprehending every thing connected with the sea, the young man at once understood that he was on a part of the reef where the water was so shallow as to admit of his wading.
