"If you both feel confident that you can swim as far, I will no longer object," said the captain. "Before you go, however, take some of the fruit; it will refresh you, although it will not add much to your strength." "Thank you, sir," exclaimed Owen, as if an especial favour had been granted him. He and Langton each ate a small portion of the fruit, both offering up in the meantime an earnest prayer for protection. "May Heaven preserve you, my lads," said the captain, as he shook their hands. Having taken off their outer clothes, retaining only their drawers, socks, and shirts, they both together slipped into the water and struck out for the shore, which could still be dimly seen. Their companions cheered as they swam from the boat. "We must not over-exert ourselves at first," said Langton, as Owen, putting forth all his strength, was shooting past him. "We shall both do it, please Heaven, but we must not be down-hearted although we appear to make but little way." Owen, taking the advice, kept pace with Langton, who maintained a slow, steady stroke. They could hear the voices of their companions, who every now and then raised a cheer to encourage them. For some time the cheers sounded almost as distinct as those at first uttered. "We can have got but a very short distance," remarked Owen. "The sound travels further than you suppose," answered Langton. "We have made good way already." On they went, every now and then speaking a word of encouragement to each other. "I am thankful you came with me," said Langton; "it would have been far more trying had I been alone." On and on they went, still the dark outline of the shore appeared as far off as ever. Now and then Langton proposed that they should turn on their backs. They could not venture to make way for any length of time in that position for fear of getting out of their proper course. Owen had somewhat overrated his strength. He began to feel his arms and legs ache, but he would not tell Langton of his sensations. At last he was compelled to propose that they should float for a short time. Langton guessed the cause, and willingly agreed. In a minute Owen felt rested, and once more they proceeded. He was again about to propose taking another rest, and was turning on his back, when he saw rising above the water, a few feet from him, a triangular fin. Though certain that it was that of a huge shark, he resolved not to tell his companion. Dreadful were his feelings. At any moment the monster might discover them. As yet it had not apparently done so. The dark fin glided on, but another and another came into sight. There might be many more astern. Not one, however, deviated from its course, and the creatures at length disappeared. Not until then did Owen utter an exclamation. "What was it?" asked Langton. Owen confessed that he had seen the sharks.
