And through it all Buck staggered along at the head of the team as in a nightmare. He pulled when he could; when he could no longer pull, he fell down and remained down till blows from whip or club drove him to his feet again. All the stiffness and gloss had gone out of his beautiful furry coat. The hair hung down, limp and draggled, or matted with dried blood where Hal’s club had bruised him. His muscles had wasted away to knotty strings, and the flesh pads had disappeared, so that each rib and every bone in his frame were outlined cleanly through the loose hide that was wrinkled in folds of emptiness. It was heartbreaking, only Buck’s heart was unbreakable. The man in the red sweater had proved that.
