"Mush, Kobuk! Sick 'im, old boy!" She forced enthusiasm into her tones. "Go head him off!"

The dog limped a few feet. He looked back at her, his ferocious look softened. His crippled leg hung useless. He raised clear, questioning eyes to her face.

"Oh, Kobuk, darling, I know—I know—" the girl's voice broke. She knelt and threw her arms about him. "But you must do something! Kobuk, you must!" She pleaded with him as if he were human.

Once more the dog looked at her, his dark, intelligent eyes fearful and sad. He gave a half-hearted little woof, shifted on his three legs and rested his head a moment against her knee.

She sprang up and ran a short distance ahead of him. Again she pointed to the bear.

"Mush, Kobuk! Oh, go after him, boy!"

He started. Once more his hair bristled ferociously. Then suddenly, to Jean's dismay, he turned and instead of heading the bear off, began to make a detour behind it. Forgetful of all else but the necessity of delaying the beast, she ran after the dog shouting encouragement.

As he left her behind he gathered speed. He swerved, making straight for the back of the bear. His woofing sounds had ceased now. He was grimly silent. The instincts of his wolf ancestors at the sight of quarry must have awakened in his heart making him forget his bodily pain, for as he sped on in his desire to maim and kill, he put his bandaged leg to the ground with increasing frequency. By the time he reached the animal, gone was the friendly, gentle Kobuk Jean had always known. In his place rushed a new and terrible Kobuk—a snarling, leaping devil-dog, with blazing eyes, white fangs gleaming in a dripping mouth, little ears laid back against a lean, wolf-like head.

He attacked the bear from behind, nipping it slightly. The huge beast stopped and whirled in clumsy astonishment. For a moment it looked almost curiously at the white-fanged fury leaping away. Then turning lumbered on again toward the mound. The monster had lived so long on Kon Klayu undisturbed by man or beast that it was apparently indifferent to both.

But Kobuk, cripple though he was, would not be ignored. Again he dashed at the bear, seeking to nip it from the rear. Again he retreated. Repeating his maneuvers he kept on, until suddenly Jean saw the beast whirl viciously. Its cumbersome bulk stiffened, its little eyes gleamed with rage. It rose on its hind feet, its monster head swaying from side to side. Then the girl stopped, horrified, dazed at the unequal battle that ensued.
