When White Fang was nearly five years old, Grey Beaver took him on another great journey, and long remembered was the havoc he worked amongst the dogs of the many villages along the Mackenzie, across the Rockies, and down the Porcupine to the Yukon. He revelled in the vengeance he wreaked upon his kind. They were ordinary, unsuspecting dogs. They were not prepared for his swiftness and directness, for his attack without warning. They did not know him for what he was, a lightning-flash of slaughter. They bristled up to him, stiff-legged and challenging, while he, wasting no time on elaborate preliminaries, snapping into action like a steel spring, was at their throats and destroying them before they knew what was happening and while they were yet in the throes of surprise.
