But in the interims between these awakenings he slept profoundly, oblivious alike to discomfort and danger—as the dead sleep.

At the first hint of dawn Bill hastily consumed the last of his unpalatable food and resumed his journey.

Hour after hour he toiled through the snow, and always the wolf-pack followed, haunting his trail in the open roadway and flanking him in the deep shade of the evergreen forest, moving tirelessly through the loose snow in long, slow leaps.

Seventeen of them he counted—seventeen murderous, ill-visaged curs of the savage kill! And the leader of the pack was a very demon wolf. A monstrous female, almost pure white, huge, misshapen, hideous—the ultimate harridan of the wolf-breed—she stood a full two hands above the tallest of the rank and file of her evil clan.

The foot and half of a foreleg had been left between iron jaws where she had gnawed herself out of a trap, and the shrunken stub, depending from a withered shoulder, dragged over the surface of the snow, leaving a curious mark like the trail of a snake.

The remaining foreleg was strong and thick and, from redistribution of balance, slanted inward from the massive shoulder, which was developed out of all proportion to its mate, giving the great white brute a repulsive, lopsided appearance.

The long, stiff hair stood out upon her neck in a great ruff, which accentuated the fiendish ferocity of her, adding a hyena-like slope to her ungainly body. But it was in the expression of her face that she reached the climax of hideous malevolence.

One pointed ear stood erect upon her head, while the other, mangled and torn into a serried red excrescence, formed the termination of a broad, ragged scar which began at the corner of her mouth, giving her face the expression of a fiendish grin that belied the green glare of her venomous, opalescent eyes.

The loss of the leg seemed in nowise to hamper her freedom of action. She moved ceaselessly among the pack with a peculiar bounding gallop, fawning in subtle cajolery upon those in the forefront, slashing right and left among the laggards with vicious clicks of her long, white fangs; and always she watched the tiring man who found his own gaze fixed upon her in horrid fascination.

There was something sinister in the wolf-pack's noiseless pursuit. The brutes drew nearer as the man's pace slowed to the wearying of his muscles.
