“No one knew his first name, and in general he was known in the country as Beauty Smith. But he was anything save a beauty. To antithesis was due his naming. He was preeminently unbeautiful. Nature had been niggardly with him.”

“In short, Beauty Smith was a monstrosity, and the blame of it lay elsewhere. He was not responsible. The clay of him had been moulded in the making.”

“As he piled wood on the fire he discovered an appreciation of his own body which he had never felt before...It fascinated him, and he grew suddenly fond of this subtle flesh of his that worked so beautifully and smoothly and delicately. Then he would cast a glance of fear at the wolf-circle drawn expectantly about him, and like a blow the realization would strike him that this wonderful body of his, this living flesh, was no more than so much meat, a quest of ravenous animals, to be torn and slashed by their hungry fangs, to be sustenance to them as the moose and the rabbit had often been sustenance to him.(Ch.3)”

“This man had saved his life, which was something; but, further, he was the ideal master. Other men saw to the welfare of their dogs from a sense of duty and business expediency; he saw to the welfare of his as if they were his own children, because he could not help it. And he saw further. He never forgot a kindly greeting or a cheering word, and to sit down for a long talk with them ("gas" he called it) was as much his delight as theirs. He had a way of taking Buck's head roughly between his hands, and resting his own head upon Buck's, of shaking him back and forth, the while calling him ill names that to Buck were love names. Buck knew no greater joy than that rough embrace and the sound of murmured oaths, and at each jerk back and forth it seemed that his heart would be shaken out of his body so great was its ecstasy. And when, released, he sprang to his feet, his mouth laughing, his eyes eloquent, his throat vibrant with unuttered sound, and in that fashion remained without movement, John Thornton would reverently exclaim, "God! you can all but speak!"Buck had a trick of love expression that was akin to hurt. He would often seize Thornton's hand in his mouth and close so fiercely that the flesh bore the impress of his teeth for some time afterward. And as Buck understood the oaths to be love words, so the man understood this feigned bite for a caress.”

“He was beaten (he knew that); but he was not broken. He saw, once for all, that he stood no chance against a man with a club. He had learned the lesson, and in all his after life he never forgot it. That club was a revelation. It was his introduction to the reign of primitive law, and he met the introduction halfway. The facts of life took on a fiercer aspect; and while he faced that aspect uncowed, he faced it with all the latent cunning of his nature aroused.”

“They were his environment, these men, and they were moulding the clay of him into a more ferocious thing than had been intended by Nature. Nevertheless, Nature had given him plasticity. Where many another animal would have died or had its spirit broken, he adjusted himself and lived, and at no expense of the spirit.”

“At the first step upon the cold surface, Buck's feet sank into a white mushy something very like mud. He sprang back with a snort. More of this white stuff was falling through the air. He shook himself, but more of it fell upon him. He sniffed it curiously, then licked some up on his tongue. It bit like fire, and the next instant was gone. This puzzled him. He tried it again, with the same result. The onlookers laughed uproariously, and he felt ashamed, he knew not why, for it was his first snow.”
