A tall lean man whose warped legs betrayed his sage-country origin leaned over and studied the signature.

"Collins," he mused. "Now whoever would have figured to cut his trail up here? He maybe was crazy,—but anyway, I'll bet five hundred that scrap of paper will pan out just like it says."

A hundred miles beyond the cabin Breed and Shady were educating their third litter of pups. The nature of the country had prevented the excavating of a proper den and Shady had taken possession of a windfall. Breed was vastly disgusted with this new land, heartily sick of being shut in by the interminable hills and of traveling through swampy jungles of tall brush, and he was glad when the pups were old enough to shift for themselves.

He gathered the pack and started on, his course this time more east than north, and he covered better than twenty miles each day with a definite purpose of leaving behind him this country so thickly overlaid with brush that its effect upon him was almost a feeling of suffocation. He came out into the lower hills and crossed occasional open spots. Then, after ten days, he crossed through a rolling country and just at dusk came out on the shoulder of a hill; before him lay broad stretches of low plains, open meadows alternating with strips of heavy timber, the whole a wonderful park-like landscape swimming in the twilight. From nearby hills he heard the coyotes beginning to tune up, and each one was facing toward the plains, the first spot they had seen in three years which reminded them of home. Breed led the way and brought his band out into the first reaches of the Mackenzie Barrens that stretched back among the trees.

Breed found no trap lines here, and there were no mad coyotes or poison baits. Another two days and the trees were left behind, open country stretching ahead as far as his eye could reach; the brush was stunted and reminded him of sage; there were clumps of dwarf spruce much like the twisted cedars of the badland brakes, and thickets of stunted willows such as those that sprouted from every side-hill spring in Sand Coulee Basin. It was like a [homecoming] after being exiled for three long years,—and Breed was content at last as he bedded on a knoll. The range was once more dotted with stock—only these were wild caribou—and old habits cropped out in Breed; he knew there were no men here, yet all through the short two-hour day he frequently raised his head and his eyes swept the range for signs of the devilish riders. When he left his bed he found fresh evidence that he was home, that Sand Coulee Basin could not be farther away than over the next tongue of high ground; for he had not traveled a mile before he smelled coyote blood and traced it upwind to find an old friend stiffened in death, and with her throat slit open,—the work of the silent assassin that had terrorized the foothills of Hardpan Spur.

Breed's hatred of Flatear had been dulled with time. He had met hundreds of wolves since the fight in the notch, and at first he had sought for his enemy, but later this search had been manifested only by a careful investigation of each new wolf he met, a vague suspicion that the big gray might be an enemy; but this had become almost a mechanical process rather than a distinct impression of why he should expect to find an enemy among wolves.

Animal memories are a mixture of impressions received through the senses of hearing, sight and smell, and after a considerable lapse of time it requires the coordination of all three of these senses to reconstruct the thought in its entirety. The sight of the slain coyote filled Breed with rage but lacking a definite object upon which to vent it. The scent around the spot further enraged him, and the picture of the great gray beast swam nebulously in his mind. A wolf howl sounded close at hand and stirred still another long-dormant pool of impressions; the whole crystallized into a distinct likeness of Flatear,—and Breed was off on the hunt for his ancient enemy.

Flatear saw a great yellow wolf rushing down on him and he whirled and bared his teeth. The gray wolf weighed a hundred pounds, Breed slightly over ninety. They circled cautiously for an opening, hind parts tensed and drooping, ears laid flat and lips drawn back to expose the yellow tusks. Flatear sprang first and Breed met the open mouth with his own. The clash of teeth sounded far across the barrens and silent shapes changed their direction and moved toward the sound. Three times Breed took the force of the drive on his teeth and the jaws of both wolves dripped blood. A wolf came slipping up to watch, and two breeds of the yellow wolf's pack stationed themselves ten yards away. Three more wolves appeared; then Peg and Fluff came to the scene and Peg moved behind Flatear and crouched.

Breed's snarl warned him off. The three-legged coyote was old and hoary, in his fifteenth year and with but a short span of life ahead; his teeth were rounded and worn down but his spirit was stout, and he longed to mix it with the wolf. His leader's order held him back, but he remained the nearest of the lot, watching every move of the combat as if appointed judge of it.

Flatear rushed time and again, using his greater weight to batter down his antagonist's guard, but Breed gave back each time and Flatear's driving shoulder never reached its mark and his teeth were met with teeth. Breed was losing ground and Flatear pressed him hard. The yellow wolf seemed to have but one style of defense and no heart for attack. The fight was a mere procession of retreats before Flatear's heavy drives, and the gray wolf grew accustomed to this monotonous defense, and his attacks were unconsciously conformed to it, becoming equally mechanical, his one purpose to wear his enemy down by sheer strength and weight.
