Dreadful as was his own injury, this fortunate thrust gave him the advantage for the moment. But, being unlearned in battle, he did not know enough to follow it up. He drew back to prepare for another charge, and paused to stamp the ground, and bellow, and shake his horribly wounded head.

The mother, heedless of her own deep wound, turned to sniff, whimpering, at the body of her cub. Seeing at once that it was quite dead, she wheeled like a flash and hurled herself again upon the slayer. As she wheeled she came upon Buck's blinded side. He lunged forward once again, mad for the struggle. But this time, half blind as he was, he was easily eluded, for the old bear was a skilled fighter. A monstrous weight crashed down upon his neck, just behind the ears, and the bright green world grew black before him. He stumbled heavily forward on knees and muzzle, with a choking bellow. The bear struck again, and with the other paw tore out his throat, falling upon him and mauling him with silent fury as he rolled over upon his side.

Star, meanwhile, being ever slow of wit and of purpose, had been watching with startled eyes, unable to take in the situation, although a strange heat was beginning to stretch his veins. But when he saw his yoke-mate stumble forward on his muzzle, when he heard that choking bellow of anguish, then the unaccustomed fire found its way up into his brain. He saw red, and, with a nimbleness far beyond that of Buck at his swiftest, he launched himself into the battle.

He launched himself into the battle.

The bear, absorbed in the fulness of her vengeance, was taken absolutely by surprise. It was as if a ton of rock had been hurled against her flank, rolling her over and crushing her at the same time. In his rage the great red ox seemed suddenly to develop an aptitude for the battle. Twisting his head, he buried one horn deep in his adversary's belly, where he ripped and tore with the all-destructive fury of a mad rhinoceros. The bear's legs closed convulsively about his head and shoulders, but in the next instant they relaxed again, falling away loosely as that ploughing horn reached and pierced the heart. Then Star drew back, and stood shaking his head to clear the blood out of his eyes.

For two days and nights Star stood over his yoke-mate's body, leaving his post only for a few yards and for a few minutes, at long intervals, to crop a mouthful of grass or to drink at that cold stream which ran past the edge of the tragic glade. On the third day two woodsmen, passing down the river in a canoe, were surprised to hear the lowing of an ox in that desolate place, far from even the remotest settler's cabin. The lowing was persistent and appealing. They went ashore and investigated.

At the scene which they came upon in the sunny little glade they stood marvelling. After a time their shrewd conjectures, initiated as they were in all the mysteries of the wild, arrived at a fairly accurate interpretation of it all.

"It was sure some scrap, anyhow," was the final conclusion of one grizzled investigator; and "Wish't we could 'a' seen it," of the other. Then, the big red ox, with blood caked over head and horns, being too admired as well as too valuable to be left behind, they decided that one of them should stop on shore and drive him, while the other followed slowly in the canoe.
