They ran through the forest at a steady pace,hour after hour,the sun rising higher and the day growing warmer.Buck was wildly glad.He knew he was at last answering the call,running by the side of his forest brother toward the place from where the call surely came.Old memories were coming upon him fast, and he was awakening to these memories from his ancestors.He had done thing before,somewhere in another world he hardly remembered,and he was doing it again.Now, he was running free in the open,the loose earth under his feet, and the wide sky over his head.~~~The wolf moved on toward the place from where the call surely came,then returned to him,touching noses and making actions as though to encourage him.But Buck turned about and started slowly walking back.
