Two weeks of lengthening days, of increasing warmth, of sunshine and hunting, followed Kazan's adventure with the porcupine. The last of the snow went rapidly. Out of the earth began to spring tips of green. The _bakneesh_ vine glistened redder each day, the poplar buds began to split, and in the sunniest spots, between the rocks of the ridges the little white snow-flowers began to give a final proof that spring had come. For the first of those two weeks Gray Wolf hunted frequently with Kazan. They did not go far. The swamp was alive with small game and each day or night they killed fresh meat. After the first week Gray Wolf hunted less. Then came the soft and balmy night, glorious in the radiance of a full spring moon when she refused to leave the windfall. Kazan did not urge her. Instinct made him understand, and he did not go far from the windfall that night in his hunt. When he returned he brought a rabbit. Came then the night when from the darkest corner of the windfall Gray Wolf warned him back with a low snarl. He stood in the opening, a rabbit between his jaws. He took no offense at the snarl, but stood for a moment, gazing into the gloom where Gray Wolf had hidden herself. Then he dropped the rabbit and lay down squarely in the opening. After a little he rose restlessly and went outside. But he did not leave the windfall. It was day when he reentered. He sniffed, as he had sniffed once before a long time ago, between the boulders at the top of the Sun Rock. That which was in the air was no longer a mystery to him. He came nearer and Gray Wolf did not snarl. She whined coaxingly as he touched her. Then his muzzle found something else. It was soft and warm and made a queer little sniffling sound. There was a responsive whine in his throat, and in the darkness came the quick soft caress of Gray Wolf's tongue. Kazan returned to the sunshine and stretched himself out before the door of the windfall. His jaws dropped open, for he was filled with a strange contentment. CHAPTER XVIII THE EDUCATION OF BA-REE
