A PURPLE rippling line upon the water had for some time been coming down upon them with great rapidity; but, bent on bloody work, they had not observed it. The boat heeled over under the sudden gust; but the ruffian had already lost his footing under Hazel's blow, and, the boom striking him almost at the same moment, he went clean over the gunwale into the sea; he struck it with his knife first.

All their lives were now gone if Cooper, who had already recovered his feet, had not immediately cut the sheet with his knife; there was no time to slack it; and, even as it was, the lower part of the sail was drenched, and the boat full of water. "Ship the helm!" he roared.

The boat righted directly the sheet was cut, the wet sail flapped furiously, and the boat, having way on her yielded to the helm and wriggled slowly away before the whistling wind.

Mackintosh rose a few yards astern, and swam after the boat, with great glaring eyes; the loose sail was not drawing, but the wind moved the boat onward. However, Mackintosh gained slowly, and Hazel held up an oar like a spear, and shouted to him that he must promise solemnly to forego all violence, or he should never come on board alive.

Mackintosh opened his mouth to reply; but, at the same moment, his eyes suddenly dilated in a fearful way, and he went under water, with a gurgling cry. Yet not like one drowning, but with a jerk.

The next moment there was a great bubbling of the water, as if displaced by some large creatures struggling below, and then the surface was stained with blood.

And, lest there should be any doubt as to the wretched man's fate, the huge black fin of a monstrous shark came soon after, gliding round and round the rolling boat, awaiting the next victim.

Now, while the water was yet stained with his life-blood, who, hurrying to kill, had met with a violent death, the unwounded sailor, Fenner, excited by the fracas, broke forth into singing, and so completed the horror of a wild and awful scene; for still, while he shouted, laughed, and sang, the shark swam calmly round and round, and the boat crept on, her white sail bespattered with blood--which was not so before--and in her bottom lay one man dead as a stone; and two poor wretches, Prince and Welch, their short-lived feud composed forever, sat openly sucking their bleeding wounds, to quench for a moment their intolerable thirst.

Oh, little do we, who never pass a single day without bite or sup, know the animal Man, in these dire extremities.
