“Oh, Mr Shobbrok, what is that dreadful creature?” she cried out. “Will it kill poor Nub? Oh, what can we do! what can we do!” She did not appear to think so much of her own and the mate’s danger as of that of the black.

The mate, for a moment, was almost unnerved, for he felt his utter inability to defend himself or the little girl should the monster attack them; still, like a brave man, he summoned up all his courage, and considered how he could possibly tackle it and defend Alice. He looked around to see if there was any spar or other floating object near at hand on which he could place her while he fought the shark. Could he find a spar, he would push it in the shark’s mouth as it swam towards him; he had likewise his clasp-knife hung round his neck, but the blade, he feared, was too blunt to be of much service; he opened it, however, and held it in his teeth ready to use. As he glanced round he saw the chest which he had observed when on the back of the whale, but it was too far off to be of any avail in the present emergency. In the meantime he had kept a vigilant watch on the hideous hammer-head, to be ready for an encounter should it dart towards him.

He had also been watching the proceedings of Nub. He soon saw that the black was manoeuvring to gain an advantage over the shark, which did not appear to observe him. Poor Alice, overcome with terror, had almost fainted in his arms; he urged her to keep up her courage.

“Don’t be afraid, Miss Alice; don’t be afraid, my child,” he said soothingly. “There is a big chest not far off, which will serve as a raft for you, and it will support Nub and me while we swim alongside it. See—see! Nub is going to tackle the shark; and he well knows, depend on it, what he is about. I have heard that the natives in these parts do not fear the creature, terrible as it looks, and I don’t see why we should. Come, we will swim towards the chest, and Nub will join us when he has finished off Jack Shark,—which he fully intends doing, depend on that.”

The mate, as he spoke, began to swim in the direction of the chest; but he soon found that, having Alice to support, he could make but slow progress; he therefore recommenced treading the water, turning his face towards the shark, that he might be the better able to encounter it should it make a dash at him. He now saw that Nub, having got close to the creature, his long knife in his hand, was swimming up alongside it. He expected, in another moment, that he would plunge his weapon into the shark’s body; but instead of that, what was his surprise to see him suddenly leap on its back and dig the fingers of one hand into its left eye. If the hammer-head had been torpid before, it now made ample amends by its sudden activity; off it darted along the surface, Nub holding up its head to prevent it from diving, while with his right hand he struck his knife with all his might sometimes before him and sometimes behind him, inflicting deep wounds in its back and sides. It seemed surprising that the zygaena could endure them, but its wonderful vitality is well-known—the terrific gashes which Nub inflicted in no way impeding its rapid progress. At first it seemed to be coming towards the mate and Alice; and though it would not have been able to bite them, it might have inflicted a blow which would have stunned them both. Nub, however, managed by hauling at its head to turn it, and it swept by, forming large circles round and round the spot where they floated. Its speed, however, from its loss of blood, began somewhat to diminish, and Nub could evidently guide it with greater ease than at first.

Seeing this, the mate shouted to him, “Steer the brute, if you can, to yonder chest, and bring it up to us as soon as possible.”

“Ay, ay, massa,” answered Nub; “I finish de brute off soon. It not got much more go in him. Cheer up, Missie Alice; I no tink dis a steady horse for you, or I ask you to have a ride on it.” (See Note 1.)

This remark did more than anything else to restore Alice’s courage, for she knew that the black felt perfectly certain of gaining the victory. Nub, who had already deprived the monster of sight, continued to dig his knife into its head, guiding it towards the chest, which he thus rapidly reached. He then, turning half round while he held up its head, stuck his knife as far back as he could reach behind him, persevering in his efforts till all movement in its tail had ceased.

“Dere, you go and feed your ugly cousins!” he exclaimed, giving it a last dig,—when, leaping from its back, he threw himself on the top of the chest; while the shark, its life almost extinct, rolled over on its back with its head downwards.

Taking off a lanyard attached to the chest, Nub secured it to the handle at one end, and after resting for a few seconds, again threw himself into the water and struck out for the mate and Alice.
