In a couple of hours the frigate was out of sight. There appeared to be every promise of fine weather. Hemming's chief concern was for the blacks, who were sickly. Several had already died, and not a day passed without four or five being added to the number. It was important, therefore, to make the passage as quickly as possible. For this object the commanding officer kept probably more sail on the ship than she would otherwise have carried. Jack one afternoon had charge of the watch; all seemed satisfactory. As he was taking a turn on deck, he saw Dick Needham hurrying towards him and pointing to the sea to leeward. It was a mass of white foam. He shouted out, "All hands shorten sail!" Hemming and Adair rushed out of the cabin. Hemming without speaking seized an axe, and began cutting away at the halyards; Adair and Jack followed his example. The crew flew into the rigging with their knives, but it was too late. The tornado was upon them; over went the ship; down, down she heeled. The seething water rushed in at her ports. Shrieks and cries arose from the unhappy negroes confined below. Jack and Needham's first impulse was to knock off the hatches, and a few blacks sprang on deck before the sea closed over their heads. "The ship is sinking, the ship is sinking," was the cry fore and aft. "Then a raft must be formed, my lads," sang out Lieutenant Hemming. "Never say die, while life remains." CHAPTER NINE. WRECK OF THE SAN FERNANDO. The heart of the bravest man may well sink within him when he hears the cry uttered, in accents of despair, "The ship is sinking, the ship is sinking!" Rogers and Adair looked at each other, and thought that their last moments had really come. All the bright visions of the future which their young imaginations had conjured up, vanished in a moment. Well might they, for the ship lay hopelessly on her side, with more than half her deck under water. There arose from every side shrieks and cries of terror. There were the distorted countenances of the blacks, as they crowded up the hatchway, through which the sea was pouring in torrents, while their own men, intent on preserving their lives to the last, were clambering up the bulwarks or working their way forward, which was the part of the ship the highest out of the water. Hemming, followed by the two midshipmen with axes in hand, endeavoured to gain the same part of the ship. It was no easy task. The howling wind blew with terrific violence around them, and the seething ocean bubbled up, and sent its fierce waves dashing over their heads. "Oh, save me, save me!" cried Adair, as a sea struck him and washed him down the deck; but Hemming and Rogers caught the rope he had happily clutched and hauled him up again. At length they gained the forecastle, where most of their own crew had assembled and some few of the unfortunate blacks. They were the only survivors of the four or five hundred human beings who
