Quote 52
They saw him marching out of camp, but they did not see the instant and terrible transformation which took place as soon as he was within the secrecy of the forest. He no longer marched. At once he became a thing of the wild, stealing along softly, cat- footed, a passing shadow that appeared and disappeared among the shadows. He knew how to take advantage of every cover, to crawl on his belly like a snake, and like a snake to leap and strike. He could take a ptarmigan from its nest, kill a rabbit as it slept, and snap in mid air the little chipmunks fleeing a second too late for the trees. Fish, in open pools, were not too quick for him; nor were beaver, mending their dams, too wary. (7.26)
Buck’s adaptation makes him a part of the natural world. Whereas he first fought with nature, now he joins nature, engraining himself in the wild.
Quote 53
At such moments, panting with red lolling tongue and with eyes fixed upon the big bull, it appeared to Buck that a change was coming over the face of things. He could feel a new stir in the land. As the moose were coming into the land, other kinds of life were coming in. Forest and stream and air seemed palpitant with their presence. The news of it was borne in upon him, not by sight, or sound, or smell, but by some other and subtler sense. He heard nothing, saw nothing, yet knew that the land was somehow different; that through it strange things were afoot and ranging. (7.33)
Buck’s own changes are reflected in the way that he sees the land around him.
Quote 54
He was glad for one thing: the rope was off his neck. That had given them an unfair advantage; but now that it was off, he would show them. They would never get another rope around his neck. Upon that he was resolved. (1.25)
Buck immediately resents being forced to submission, but his initial claims of defiance are impossible to fulfill.
