Chapter Eight.

The Whale sinks—Alice supported by the Mate—A Hammer-Headed Shark appears—Alice’s Alarm—Nub conquers the Hammer-head—Voyage on a Sea-Chest.

The huge monster rolling over, slowly sank head foremost into the depths of the ocean; possibly from the oil in the case by some means or other having escaped, thereby depriving it of its buoyancy—an occurrence which occasionally takes place when, after a hard chase, a whale has been captured, and the victors are about to tow it in triumph to their ship; losing in consequence several hundred pounds worth of oil.

The mate and Nub found themselves dragged a considerable way under water; but quickly coming up again, as they were striking out they caught sight of the raft driving before the wind, and poor Alice struggling in the water at some distance from them. Horror-struck at the sight, they swam towards her, their hearts beating with anxiety lest they should not be in time to reach the spot ere she sank beneath the surface, or was seized by one of the ravenous sharks from which Nub had just before so narrowly escaped. Happily the savage creatures had darted down after the whale, eager to seize the strips of blubber which had been cut off its back. So busily were they engaged, that they did not take notice of the human beings thus left to their tender mercies. The mate had been on a part of the whale nearest Alice, and was thus the first to approach her. Seeing the impossibility of reaching the raft, he shouted to Nub and told him to swim after it; he himself intending to assist Alice, who was stretching out her arms and piteously calling to him for help.

Walter, who had gone off into a state of dreamy unconsciousness as he lay stretched on the raft, on hearing Alice shriek out at the moment she was dragged into the water, started up, his senses completely bewildered, and instead of lowering the sail, stood waving his hands, and incoherently shrieking out to her to come to him. The mate shouted to him to lower the sail; but he did not understand the order, and continued leaping frantically about the raft, waving his hands and shrieking as before. The consequence was that the raft got further and further away, at a rate which gave but little hope that Nub would overtake it. The mate’s brave heart almost died within him at the thought that not his life only, but that of the little girl and Nub, would be sacrificed. Nub was exerting himself to the utmost. Never had he swam so fast. But he soon saw that all his efforts would not enable him to overtake the raft. Again and again he shouted to Walter to lower the sail: Walter only shrieked louder in return, calling him to come to his help—and Nub expected every moment to see him leap into the water, when, in all probability, he would be drowned. Still the brave black persevered.

“Lower de sail, Massa Walter, lower de sail!” he shouted; “you all right if you do dat. De mate save Missie Alice, so no fear about her. Lower de sail! Oh, de poor boy gone mad!”

In vain Nub shouted; Walter only waved his hands more frantically, till, overcome by terror, he sank down exhausted on the raft, and Nub saw that it would be impossible to overtake it while it continued running at its present speed. The only hope was that the wind might drop, or shift, and bring it back to them. This, however, was barely probable; the breeze was blowing fresh, and the light raft, having now no longer their weight on it, skimmed swiftly over the surface. Still Nub persevered in endeavouring to obey the mate’s orders; he was ready to swim on till he sank exhausted. Happily he was as much at home in the water as on shore, and by turning on his back or treading water, or swimming in a variety of other ways, could keep up for several hours together.

He turned his head round and saw that the mate had reached Alice and was supporting her in his arms. “De mate swim well, I know, so he keep up de little girl while I go after de raft,” he said to himself, and he again made way; but though he swam rapidly, the raft skimmed along at a still faster rate, and had he not even yet trusted to the possibility of either a change of wind or a calm, he would have given up the attempt as hopeless. He thought, too, that Walter might perhaps regain his senses, and do what alone could preserve his own life and that of his friends. Left by himself on the raft, he must inevitably perish as well as they. Inspired by this hope, the gallant black pursued his course undaunted by the recollection of the shoal of ravenous sharks which he knew were in the neighbourhood, or by the want of any object, as far as he could see before him, on which to rest. Fearful as was his condition, it was to become still more terrible. He had just glanced round and shouted to the mate and Alice to keep up their courage, when, as he again turned his face towards the raft, he saw, not twenty fathoms from him, a hideous head, such as the morbid imagination sometimes pictures during a dreadful dream. The front was of immense width, with large, savage eyes glaring out at either side; while below appeared a large mouth, full of formidable teeth; the body, as Nub knew, being in proportion to the size of the head. It was indeed an enormous specimen of the hideous zygaena, or hammer-headed shark, so frequently observed about the coast of the South Sea islands, and scarcely less voracious and formidable than the terrible white shark, the sailor’s hated foe. Its body was comparatively slender, but its head was dilated on each side to a prodigious extent,—the form being that of a double-headed hammer, from which it takes the name of “the hammer-headed shark.”

Nub gazed at the creature, but his courage did not fail him. It had apparently only just come to the surface to gaze about it, and had not yet discovered the human beings floating near. The black had often seen the shark bravely attacked by the natives of Otaheite and other islands, who encounter it fearlessly as they swim off through the raging surf, and never fail to return victorious to the shore. There was no time, however, for consideration, for with a few turns of its tail the monster might be up to him. He had, fortunately, a large, sharp sheath-knife sticking in his girdle; he drew it, and keeping his eye on the shark, he struck out so as to gain a position rather behind the creature’s head, which was turned from him. At the same moment that Nub caught sight of the zygaena the mate also saw it; he fully expected that it would dash at the black and seize him in its dreadful jaws. The shark, however, was either of a sluggish nature, or perhaps gorged with food, for its head remained above water without moving from the spot where it had at first appeared. The mate endeavoured to prevent Alice from seeing the hammer-head, but her eyes unfortunately fell on it.
