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.

By afternoon, Perrault, who was in a hurry to be on the trail with his despatches, returned with two more dogs. "Billee" and "Joe" he called them, two brothers, and true huskies both. Sons of the one mother though they were, they were as different as day and night. Billee's one fault was his excessive good nature, while Joe was the very opposite, sour and introspective, with a perpetual snarl and a malignant eye. Buck received them in comradely fashion, Dave ignored them, while Spitz proceeded to thrash first one and then the other. Billee wagged his tail appeasingly, turned to run when he saw that appeasement was of no avail, and cried (still appeasingly) when Spitz's sharp teeth scored his flank. But no matter how Spitz circled, Joe whirled around on his heels to face him, mane bristling, ears laid back, lips writhing and snarling, jaws clipping together as fast as he could snap, and eyes diabolically gleaming–the incarnation of belligerent fear. So terrible was his appearance that Spitz was forced to forego disciplining him; but to cover his own discomfiture he turned upon the inoffensive and wailing Billee and drove him to the confines of the camp.

By evening Perrault secured another dog, an old husky, long and lean and gaunt, with a battle–scarred face and a single eye which flashed a warning of prowess that commanded respect. He was called Sol–leks, which means the Angry One. Like Dave, he asked nothing, gave nothing, expected nothing; and when he marched slowly and deliberately into their midst, even Spitz left him alone. He had one peculiarity which Buck was unlucky enough to discover. He did not like to be approached on his blind side. Of this offence Buck was unwittingly guilty, and the first knowledge he had of his indiscretion was when Sol–leks whirled upon him and slashed his shoulder to the bone for three inches up and down. Forever after Buck avoided his blind side, and to the last of their comradeship had no more trouble. His only apparent ambition, like Dave's, was to be left alone; though, as Buck was afterward to learn, each of them possessed one other and even more vital ambition.

That night Buck faced the great problem of sleeping. The tent, illumined by a candle, glowed warmly in the midst of the white plain; and when he, as a matter of course, entered it, both Perrault and Francois bombarded him with curses and cooking utensils, till he recovered from his consternation and fled ignominiously into the outer cold. A chill wind was blowing that nipped him sharply and bit with especial venom into his wounded shoulder. He lay down on the snow and attempted to sleep, but the frost soon drove him shivering to his feet. Miserable and disconsolate, he wandered about among the many tents, only to find that one place was as cold as another. Here and there savage dogs rushed upon him, but he bristled his neck–hair and snarled (for he was learning fast), and they let him go his way unmolested.

The dominant primordial beast was strong in Buck, and under the fierce conditions of trail life it grew and grew. Yet it was a secret growth. His newborn cunning gave him poise and control. He was too busy adjusting himself to the new life to feel at ease, and not only did he not pick fights, but he avoided them whenever possible. A certain deliberateness characterized his attitude. He was not prone to rashness and precipitate action; and in the bitter hatred between him and Spitz he betrayed no impatience, shunned all offensive acts.

On the other hand, possibly because he divined in Buck a dangerous rival, Spitz never lost an opportunity of showing his teeth. He even went out of his way to bully Buck, striving constantly to start the fight which could end only in the death of one or the other. Early in the trip this might have taken place had it not been for an unwonted accident. At the end of this day they made a bleak and miserable camp on the shore of Lake Le Barge. Driving snow, a wind that cut like a white–hot knife, and darkness had forced them to grope for a camping place. They could hardly have fared worse. At their backs rose a perpendicular wall of rock, and Perrault and Francois were compelled to make their fire and spread their sleeping robes on the ice of the lake itself. The tent they had discarded at Dyea in order to travel light. A few sticks of driftwood furnished them with a fire that thawed down through the ice and left them to eat supper in the dark.

Close in under the sheltering rock Buck made his nest. So snug and warm was it, that he was loath to leave it when Francois distributed the fish which he had first thawed over the fire. But when Buck finished his ration and returned, he found his nest occupied. A warning snarl told him that the trespasser was Spitz. Till now Buck had avoided trouble with his enemy, but this was too much. The beast in him roared. He sprang upon Spitz with a fury which surprised them both, and Spitz particularly, for his whole experience with Buck had gone to teach him that his rival was an unusually timid dog, who managed to hold his own only because of his great weight and size.

This accomplished, the outfit, though cut in half, was still a formidable bulk. Charles and Hal went out in the evening and bought six Outside dogs. These, added to the six of the original team, and Teek and Koona, the huskies obtained at the Rink Rapids on the record trip, brought the team up to fourteen. But the Outside dogs, though practically broken in since their landing, did not amount to much. Three were short–haired pointers, one was a Newfoundland, and the other two were mongrels of indeterminate breed. They did not seem to know anything, these newcomers. Buck and his comrades looked upon them with disgust, and though he speedily taught them their places and what not to do, he could not teach them what to do. They did not take kindly to trace and trail. With the exception of the two mongrels, they were bewildered and spirit–broken by the strange savage environment in which they found themselves and by the ill treatment they had received. The two mongrels were without spirit at all; bones were the only things breakable about them.

With the newcomers hopeless and forlorn, and the old team worn out by twenty–five hundred miles of continuous trail, the outlook was anything but bright. The two men, however, were quite cheerful. And they were proud, too. They were doing the thing in style, with fourteen dogs. They had seen other sleds depart over the Pass for Dawson, or come in from Dawson, but never had they seen a sled with so many as fourteen dogs. In the nature of Arctic travel there was a reason why fourteen dogs should not drag one sled, and that was that one sled could not carry the food for fourteen dogs. But Charles and Hal did not know this. They had worked the trip out with a pencil, so much to a dog, so many dogs, so many days, Q.E.D. Mercedes looked over their shoulders and nodded comprehensively, it was all so very simple.

Late next morning Buck led the long team up the street. There was nothing lively about it, no snap or go in him and his fellows. They were starting dead weary. Four times he had covered the distance between Salt Water and Dawson, and the knowledge that, jaded and tired, he was facing the same trail once more, made him bitter. His heart was not in the work, nor was the heart of any dog. The Outsides were timid and frightened, the Insides without confidence in their masters.

He had made no noise, yet it ceased from its howling and tried to sense his presence. Buck stalked into the open, half crouching, body gathered compactly together, tail straight and stiff, feet falling with unwonted care. Every movement advertised commingled threatening and overture of friendliness. It was the menacing truce that marks the meeting of wild beasts that prey. But the wolf fled at sight of him. He followed, with wild leapings, in a frenzy to overtake. He ran him into a blind channel, in the bed of the creek where a timber jam barred the way. The wolf whirled about, pivoting on his hind legs after the fashion of Joe and of all cornered husky dogs, snarling and bristling, clipping his teeth together in a continuous and rapid succession of snaps.

Buck did not attack, but circled him about and hedged him in with friendly advances. The wolf was suspicious and afraid; for Buck made three of him in weight, while his head barely reached Buck's shoulder. Watching his chance, he darted away, and the chase was resumed. Time and again he was cornered, and the thing repeated, though he was in poor condition, or Buck could not so easily have overtaken him. He would run till Buck's head was even with his flank, when he would whirl around at bay, only to dash away again at the first opportunity.

But in the end Buck's pertinacity was rewarded; for the wolf, finding that no harm was intended, finally sniffed noses with him. Then they became friendly, and played about in the nervous, half–coy way with which fierce beasts belie their fierceness. After some time of this the wolf started off at an easy lope in a manner that plainly showed he was going somewhere. He made it clear to Buck that he was to come, and they ran side by side through the sombre twilight, straight up the creek bed, into the gorge from which it issued, and across the bleak divide where it took its rise.
