An outcast himself from the pack of the part-grown dogs, his sanguinary methods and remarkable efficiency made the pack pay for its persecution of him. Not permitted himself to run with the pack, the curious state of affairs obtained that no member of the pack could run outside the pack. White Fang would not permit it.
