And Buck was truly a red-eyed devil, as he drew himself together for the spring, hair bristling, mouth foaming, a mad glitter in his blood-shot eyes. Straight at the man he launched his one hundred and forty pounds of fury, surcharged with the pent passion of two days and nights. In mid air, just as his jaws were about to close on the man, he received a shock that checked his body and brought his teeth together with an agonizing clip. He whirled over, fetching the ground on his back and side. He had never been struck by a club in his life, and did not understand. With a snarl that was part bark and more scream he was again on his feet and launched into the air. And again the shock came and he was brought crushingly to the ground. This time he was aware that it was the club, but his madness knew no caution. A dozen times he charged, and as often the club broke the charge and smashed him down.

After a particularly fierce blow he crawled to his feet, too dazed to rush. He staggered limply about, the blood flowing from nose and mouth and ears, his beautiful coat sprayed and flecked with bloody slaver. Then the man advanced and deliberately dealt him a frightful blow on the nose. All the pain he had endured was as nothing compared with the exquisite agony of this. With a roar that was almost lionlike in its ferocity, he again hurled himself at the man. But the man, shifting the club from right to left, coolly caught him by the under jaw, at the same time wrenching downward and backward. Buck described a complete circle in the air, and half of another, then crashed to the ground on his head and chest.

For the last time he rushed. The man struck the shrewd blow he had purposely withheld for so long, and Buck crumpled up and went down, knocked utterly senseless.

“He’s no slouch at dog-breakin’, that’s wot I say,” one of the men on the wall cried enthusiastically.

“Druther break cayuses any day, and twice on Sundays,” was the reply of the driver, as he climbed on the wagon and started the horses.

Buck’s senses came back to him, but not his strength. He lay where he had fallen, and from there he watched the man in the red sweater.

“ ‘Answers to the name of Buck,’ ” the man soliloquized, quoting from the saloon-keeper’s letter which had announced the consignment of the crate and contents. “Well, Buck, my boy,” he went on in a genial voice, “we’ve had our little ruction, and the best thing we can do is to let it go at that. You’ve learned your place, and I know mine. Be a good dog and all ’ll go well and the goose hang high. Be a bad dog, and I’ll whale the stuffin’ outa you. Understand?”

As he spoke he fearlessly patted the head he had so mercilessly pounded, and though Buck’s hair involuntarily bristled at touch of the hand, he endured it without protest. When the man brought him water he drank eagerly, and later bolted a generous meal of raw meat, chunk by chunk, from the man’s hand.

He was beaten (he knew that); but he was not broken. He saw, once for all, that he stood no chance against a man with a club. He had learned the lesson, and in all his after life he never forgot it. That club was a revelation. It was his introduction to the reign of primitive law, and he met the introduction halfway. The facts of life took on a fiercer aspect; and while he faced that aspect uncowed, he faced it with all the latent cunning of his nature aroused. As the days went by, other dogs came, in crates and at the ends of ropes, some docilely, and some raging and roaring as he had come; and, one and all, he watched them pass under the dominion of the man in the red sweater. Again and again, as he looked at each brutal performance, the lesson was driven home to Buck: a man with a club was a law-giver, a master to be obeyed, though not necessarily conciliated. Of this last Buck was never guilty, though he did see beaten dogs that fawned upon the man, and wagged their tails, and licked his hand. Also he saw one dog, that would neither conciliate nor obey finally killed in the struggle for mastery.

Now and again men came, strangers, who talked excitedly, wheedling, and in all kinds of fashions to the man in the red sweater. And at such times that money passed between them the strangers took one or more of the dogs away with them. Buck wondered where they went, for they never came back; but the fear of the future was strong upon him, and he was glad each time when he was not selected.
