Kazan's blood was fomented with brute exultation, and the excitement and fascination that came in the possession of new power took the place of Gray Wolf each day a little more. She came in half an hour after the kill, and there was no longer the lithesome alertness to her slender legs, or gladness in the tilt of her ears or the poise of her head. She did not eat much of the doe. Her blind face was turned always in Kazan's direction. Wherever he moved she followed with her unseeing eyes, as if expecting each moment his old signal to her--that low throat-note that had called to her so often when they were alone in the wilderness. In Kazan, as leader of the pack, there was working a curious change. If his mates had been wolves it would not have been difficult for Gray Wolf to have lured him away. But Kazan was among his own kind. He was a dog. And they were dogs. Fires that had burned down and ceased to warm him flamed up in him anew. In his life with Gray Wolf one thing had oppressed him as it could not oppress her, and that thing was loneliness. Nature had created him of that kind which requires companionship--not of one but of many. It had given him birth that he might listen to and obey the commands of the voice of man. He had grown to hate men, but of the dogs--his kind--he was a part. He had been happy with Gray Wolf, happier than he had ever been in the companionship of men and his blood-brothers. But he had been a long time separated from the life that had once been his and the call of blood made him for a time forget. And only Gray Wolf, with that wonderful super-instinct which nature was giving her in place of her lost sight, foresaw the end to which it was leading him. Each day the temperature continued to rise until when the sun was warmest the snow began to thaw a little. This was two weeks after the fight near the bull. Gradually the pack had swung eastward, until it was now fifty miles east and twenty miles south of the old home under the windfall. More than ever Gray Wolf began to long for their old nest under the fallen trees. Again with those first promises of spring in sunshine and air, there was coming also for the second time in her life the promise of approaching motherhood. But her efforts to draw Kazan back were unavailing, and in spite of her protest he wandered each day a little farther east and south at the head of his pack. Instinct impelled the four huskies to move in that direction. They had not yet been long enough a part of the wild to forget the necessity of man and in that direction there was man. In that direction, and not far from them now, was the Hudson Bay Company's post to which they and their dead master owed their allegiance. Kazan did not know this, but one day something happened to bring back visions and desires that widened still more the gulf between him and Gray Wolf.
