In her blindness Gray Wolf could no longer hunt with her mate. But gradually a new code of understanding grew up between them, and through her blindness they learned many things that they had not known before. By early summer Gray Wolf could travel with Kazan, if he did not move too swiftly. She ran at his flank, with her shoulder or muzzle touching him, and Kazan learned not to leap, but to trot. Very quickly he found that he must choose the easiest trails for Gray Wolf's feet. When they came to a space to be bridged by a leap, he would muzzle Gray Wolf and whine, and she would stand with ears alert--listening. Then Kazan would take the leap, and she understood the distance she had to cover. She always over-leaped, which was a good fault. In another way, and one that was destined to serve them many times in the future, she became of greater help than ever to Kazan. Scent and hearing entirely took the place of sight. Each day developed these senses more and more, and at the same time there developed between them the dumb language whereby she could impress upon Kazan what she had discovered by scent or sound. It became a curious habit of Kazan's always to look at Gray Wolf when they stopped to listen, or to scent the air. After the fight on the Sun Rock, Kazan had taken his blind mate to a thick clump of spruce and balsam in the river-bottom, where they remained until early summer. Every day for weeks Kazan went to the cabin where Joan and the baby--and the man--had been. For a long time he went hopefully, looking each day or night to see some sign of life there. But the door was never open. The boards and saplings at the windows always remained. Never a spiral of smoke rose from the clay chimney. Grass and vines began to grow in the path. And fainter and fainter grew that scent which Kazan could still find about it--the scent of man, of the woman, the baby. One day he found a little baby moccasin under one of the closed windows. It was old, and worn out, and blackened by snow and rain, but he lay down beside it, and remained there for a long time, while the baby Joan--a thousand miles away--was playing with the strange toys of civilization. Then he returned to Gray Wolf among the spruce and balsam. The cabin was the one place to which Gray Wolf would not follow him. At all other times she was at his side. Now that she had become accustomed to blindness, she even accompanied him on his hunts, until he struck game, and began the chase. Then she would wait for him. Kazan usually hunted the big snow-shoe rabbits. But one night he ran down and killed a young doe. The kill was too heavy to drag to Gray Wolf, so he returned to where she was waiting for him and guided her to the feast. In many ways they became more and more inseparable as the summer lengthened, until at last, through all the wilderness, their footprints were always two by two and never one by one. Then came the great fire.
