And over this great demense Buck ruled. Here he was born, and here he had lived the four years of his life. It was true. there were other dogs. There could not but be other dogs on so vast a place, but they did not count, They came and went. resided in the populous kennels, or lived obscurely in the recesses of the house after the fashion of Toots, the Japanese pug, or Ysabel, the Mexican hairless--strange creatures that rarely put nose out of doors or set foot to ground. On the other hand, there were the fox terriers, a score of them at least, who yelped fearful promises at Toots and Ysabel looking out of the windows at them and protected by a legion of housemaids armed with brooms and mops. But Buck was neither house-dog nor kennel dog. The whole realm was his. He plunged into the swimming tank or went hunting with the Judge's sons; he escorted Mollie and Alice. the Judge's daughters, on long twilight or early morning rambles; on wintry nights he lay at the Judge's feet before the roaring library fire; he carried the Judge's grandsons on his back. or rolled them in the grass, and guarded their footsteps through wild adventures down to the fountain in the stable yard. and even beyond, where the paddocks were, and the berry patches. Among the terriers he stalked imperiously, and Toots and Ysabel he utterly ignored. for he was king--king over all creeping. crawling, flying things of Judge Miller's place, humans included. His father. Elmo, a huge St. Bernard, had been the Judge's inseparable companion. and Buck bid fair to follow in the way of his father. He was not so large--he weighed only one hundred and forty pounds--for his mother, Shep, had been a Scotch shepherd dog. Nevertheless, one hundred and forty pounds, to which was added the dignity that comes of good living and universal respect. enabled him to carry himself in right royal fashion. During the four years since his puppyhood he had lived the life of a sated aristocrat; he had a fine pride in himself, was ever a trifle egotistical. as country gentlemen sometimes become because of their insular situation. But he had saved himself by not becoming a mere pampered house dog. Hunting and kindred outdoor delights had kept down the fat and hardened his muscles; and to him, as to the cold tubbing-races, the love of water had been a tonic and a health preserver. And this was the manner of dog Buck was in the fall of 1897, when the Klondike strike dragged men from all the world into the frozen North. But Buck did not read the newspapers. and he did not know that Manuel, one of the gardener's helpers, was an undesirable acquaintance. Manuel had one besetting sin. He loved to play Chinese lottery. Also, in his gambling. he had one besetting weakness-faith in a system. and this made his damnation certain. For to play a system requires money, while the wages of a gardener's helper do not lap over the needs of a wife and numerous progeny.
