“He was mastered by the sheer surging of life, the tidal wave of being, the perfect joy of each separate muscle, joint, and sinew in that it was everything that was not death, that it was aglow and rampant, expressing itself in movement, flying exultantly under the stars.”

“He became quicker of movement than the other dogs, swifter of foot, craftier, deadlier, more lithe, more lean with ironlike muscle and sinew, more enduring, more cruel more ferocious, and more intelligent. He had to become all these things, else he would not have held his own nor survived the hostile environment in which he found himself.”

“This expression of abandon and surrender, of absolute trust, he reserved for the master alone.”

“...his ardors and toils were in themselves self-remunerative. They were expressions of life, and life is always happy when it is expressing itself.”

“He must master or be mastered; while to show mecy was a weakness. Mercy did not exist in the primordial life. It was misunderstood for fear, and such misunderstandings made for death. Kill or be killed, eat or be eaten, was the law; and this mandate, down out of the depths of Time, he obeyed.”

“A vast silence reigned over the land. The land itself was a desolation, lifeless, without movement, so lone and cold that the spirit of it was not even that of sadness. There was a hint in it of laughter, but of laughter more terrible than any sadness-a laughter that was mirthless as the smile of the Sphinx, a laughter cold as the frost and partaking of the grimness of infallibility. It was the masterful and incommunicable wisdom of eternity laughing at the futility of life and the effort of life. It was the Wild, the savage, frozen-hearted Northland Wild.”

“He had learned well the law of club and fang, and he never forewent an advantage or drew back from a foe he had started on the way to Death. He had lessoned from Spitz, and from the chief fighting dogs of the police and mail, and knew there was no middle course. He must master or be mastered; while to show mercy was a weakness. mercy did not exist in the primordial life. It was misunderstood for fear, and such misunderstandings made for death. Kill or be killed, eat or be eaten, was the law; and this mandate, down out of the depths of Time, he obeyed.”
