"That for the sharks!" burst almost simultaneously from the parched lips of the group: "we'll have a jolly good bath when the second mate goes in to dinner." In about half an hour the dinner-bell rang. The boatswain took charge of the deck; some twenty sailors were now stripped, except a pair of light duck trowsers; among the rest was a tall, powerful, coast-of-Africa nigger of the name of Leigh: they used to joke him, and call him Sambo. "You no swim to-day, Ned?" said he, addressing me. "Feared of shark, heh? Shark nebber bite me. Suppose I meet shark in water, I swim after him--him run like debbel." I was tempted, and, like the rest, was soon ready. In quick succession we jumped off the spritsail yard, the black leading. We had scarcely been in the water five minutes, when some voice in-board cried out, "A shark! a shark!" In an instant every one of the swimmers came tumbling up the ship's sides, half mad with fright, the gallant black among the rest. It was a false alarm. We felt angry with ourselves for being frightened, angry with those who had frightened us, and furious with those who had laughed at us. In another moment we were all again in the water, the black and myself swimming some distance from the ship. For two successive voyages there had been a sort of rivalry between us: each fancied that he was the best swimmer, and we were now testing our speed. "Well done, Ned!" cried some of the sailors from the forecastle. "Go it, Sambo!" cried some others. We were both straining our utmost, excited by the cheers of our respective partisans. Suddenly the voice of the boatswain was heard shouting, "A shark! a shark! Come back for God's sake!" "Lay aft, and lower the cutter down," then came faintly on our ear. The race instantly ceased. As yet, we only half believed what we heard, our recent fright being still fresh in our memories. "Swim, for God's sake!" cried the captain, who was now on deck; "he has not yet seen you. The boat, if possible, will get between you and him. Strike out, lads, for God's sake!" My heart stood still: I felt weaker than a child as I gazed with horror at the dorsal fin of a large shark on the starboard quarter. Though in the water, the perspiration dropped from me like rain: the black was striking out like mad for the ship. "Swim, Ned--swim!" cried several voices; "they never take black when they can get white." I did swim, and that desperately: the water foamed past me. I soon breasted the black, but could not head him. We both strained every nerve to be first, for we each fancied the last man would be taken. Yet we scarcely seemed to move: the ship appeared as far as ever from us. We were both powerful swimmers, and both of us swam in the French way called _la brasse_, or hand over hand, in English. There was something the matter with the boat's falls, and they could not lower her.
