"Dark spruce forest frowned on either side the frozen waterway. The trees had been stripped bya recent wind of their white covering of frost, and they seemed to lean toward each other, blackand ominous, in the fading light. A vast silence reigned over the land. The land itself was adesolation, lifeless, without movement, so lone and cold that the spirit of it was not even thatof sadness. There was a hint in it of laughter, but of a laughter more terrible than any sadness—a laughter that was mirthless as the smile of the Sphinx, a laughter cold as the frost andpartaking of the grimness of infallibility. It was the masterful and incommunicable wisdom ofeternity laughing at the futility of life and the effort of life. It was the Wild, the savage, frozen-hearted Northland Wild." JACK LONDON, WHITE FANG
