Quotation from: The Call of the Wild

Into the Primitive

"Old longings nomadic leap,
Chafing at custom's chain;
Again from its brumal sleep
Wakens the ferine strain."

Buck did not read the newspapers, or he would have known that
trouble was brewing, not alone for himself, but for every tide-
water dog, strong of muscle and with warm, long hair, from Puget
Sound to San Diego. Because men, groping in the Arctic darkness,
had found a yellow metal, and because steamship and transportation
companies were booming the find, thousands of men were rushing
into the Northland. These men wanted dogs, and the dogs they
wanted were heavy dogs, with strong muscles by which to toil, and
furry coats to protect them from the frost.
