"Well heave the ship to, and lower a couple of boats to go in search of the lads," observed the captain. The first lieutenant issued the necessary orders, and the ship was brought up to the wind and hove-to. Mr Thorn eagerly went to lower one of the boats. Hemming took charge of the other. Their respective crews sprang into them. The falls were properly tended and unhooked at the right moment, and, getting clear of the ship, they lay ready to pull in whatever direction might be indicated. Here was the difficulty. "Silence fore and aft," sang out the captain. "Does any one hear them?" In an instant there was a dead silence. No one would have supposed that many hundred human beings were at that moment alive and awake on board the ship. Every one listened intently, but no sound was borne to their ears. Even Captain Lascelles began to give up all hope. "The poor widowed mother, how will she bear it?" he muttered; "and that honest country gentleman--it will be sad news I shall have to send him of his son." Scarcely had the captain thus given expression to his feelings, when a bright light burst forth amid the darkness some way to leeward. A shout spontaneously arose from all on board. "They must have got hold of the life-buoy, they must have got hold of the life-buoy," was the cry. "Hurrah! hurrah!" The two boats dashed away, with eager strokes, in the direction of the light. Meantime Murray had towed Jack steadily on towards the buoy. He began to feel very weary though, and sometimes he thought that his strength would fail him. He looked at the buoy; it seemed a very long way off. He felt at last that he should never be able to reach it. "I'll not give in while life remains," he said to himself. Just then his hand struck against something. He grasped it. It was a large piece of Spanish cork-wood. He shoved it under Jack's back, and rested his own left arm on it. He immediately found an immense advantage from the support it afforded. "Who sent that piece of cork-wood to my aid?" he thought; "it did not come by chance." The assurance that he was not deserted gave him additional confidence. Jack also gave further signs of returning animation. "Where am I?" he at length asked, in a tone of voice which showed that his senses were still confused. "In the middle of the Mediterranean; but there's a life-buoy close at hand, and when we get hold of it we shall be all to rights," answered Murray. "What! is that you, Alick?" asked jack. "I remember now feeling that I was going overboard; but how came you here? Has the ship gone down?" "No, no; all right; she'll be here to pick us up directly, I hope." "Then you jumped overboard to save me!" exclaimed Jack. "Just like you, Alick; I knew you would do it." Jack lay perfectly still all the time he was talking. It did not seem to occur to him that he could swim as well as his companion.
