But the dogs could never learn the lesson to leave him alone in camp. Each day, pursuing him and crying defiance at him, the lesson of the previous night was erased, and that night would have to be learned over again, to be as immediately forgotten. Besides, there was a greater consistence in their dislike of him. They sensed between themselves and him a difference of kind—cause sufficient in itself for hostility. Like him, they were domesticated wolves. But they had been domesticated for generations. Much of the Wild had been lost, so that to them the Wild was the unknown, the terrible, the ever-menacing and ever warring. But to him, in appearance and action and impulse, still clung the Wild. He symbolised it, was its personification: so that when they showed their teeth to him they were defending themselves against the powers of destruction that lurked in the shadows of the forest and in the dark beyond the camp-fire. But there was one lesson the dogs did learn, and that was to keep together. White Fang was too terrible for any of them to face single-handed. They met him with the mass-formation, otherwise he would have killed them, one by one, in a night. As it was, he never had a chance to kill them. He might roll a dog off its feet, but the pack would be upon him before he could follow up and deliver the deadly throat-stroke. At the first hint of conflict, the whole team drew together and faced him. The dogs had quarrels among themselves, but these were forgotten when trouble was brewing with White Fang. On the other hand, try as they would, they could not kill White Fang. He was too quick for them, too formidable, too wise. He avoided tight places and always backed out of it when they bade fair to surround him. While, as for getting him off his feet, there was no dog among them capable of doing the trick. His feet clung to the earth with the same tenacity that he clung to life. For that matter, life and footing were synonymous in this unending warfare with the pack, and none knew it better than White Fang. So he became the enemy of his kind, domesticated wolves that they were, softened by the fires of man, weakened in the sheltering shadow of man’s strength. White Fang was bitter and implacable. The clay of him was so moulded. He declared a vendetta against all dogs. And so terribly did he live this vendetta that Grey Beaver, fierce savage himself, could not but marvel at White Fang’s ferocity. Never, he swore, had there been the like of this animal; and the Indians in strange villages swore likewise when they considered the tale of his killings amongst their dogs.
