must get hardened. He had started out preaching it to his sister and brother-in-law. Failing there, he hammered it into the dogs with a club. At the Five Fingers the dog-food gave out, and a toothless old squaw offered to trade them a few pounds of frozen horsehide for the Colt’s revolver that kept the big hunting-knife company at Hal’s hip. A poor substitute for food was this hide, just as it had been stripped from the starved horses of the cattlemen six months back. In its frozen state it was more like strips of galvanized iron, and when a dog wrestled it into his stomach it thawed into thin and innutritious leathery strings and into a mass of short hair, irritating and indigestible.
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.
As it was with Buck, so was it with his mates. They were perambulating skeletons. There were seven all together, including him. In their very great misery they had become insensible to the bite of the lash or the bruise of the club. The pain of the beating was dull and distant, just as the things their eyes saw and their ears heard seemed dull and distant. They were not half living, or quarter living. They were simply so many bags of bones in which sparks of life fluttered faintly. When a halt was made, they dropped down in the traces like dead dogs, and the spark dimmed and paled and seemed to go out. And when the club or whip fell upon them, the spark fluttered feebly up, and they tottered to their feet and staggered on.
