He drew him to the fire and by its light pointed them out. Dat Spitz fight like hell, said Perrault, as he surveyed the gaping rips and cuts. An39。s answer. And now we make good time. No more Spitz, no more trouble, sure. While Perrault packed the camp outfit and loaded the sled, the dogdriver proceeded to harness the dogs. Buck trotted up to the place Spitz would have occupied as leader。way, Hook! he cried, but Buck refused to budge. He took Buc k by the scruff of the neck, and though the dog growled threateningly, dragged him to one side and replaced Solle ks. T he old dog did not like it, and showed plainly that he was afraid of Buc k. Francois was obdurate, but when he turned his back, Buck again displaced Solleks, who was not at all unwilling to go. Francois was angry. Now, by Gar, I fix you! he cried, ing back with a heavy club in his hand. Buc k remembered the man in the red sweater, and retreated slow ly。 and while he circled he watched the club so as to dodge it if thrown by Francois, for he was bee wise in the way of clubs. The driver went about his work, and he called to Buc k when he was ready to put him in his old place in front of Dave. Buck re treated two or three steps. Francois followed him up, whereupon he again retreated. After some time of this, Francois threw down the club, thinking that Buc k feared a thrashing. But Buc k was in open revolt. He wanted, not to escape a clubbing, but to have the leadership. It was his by right. He had earned it, and he would not be content with less. Perrault took a hand. Between them they ran him about for the better part of an hour. They threw clubs at him. He dodged.

The team stood harnessed to the sled in an unbroken line, ready for the trail. T here was no place for Buc k save at the front. Once more Francois called, and once more Buck laughed and kept away. Throw down de club, Perrault manded. Francois plied, w hereupon Buck trotted in, laughing tr iumphantly, and swung around into position at the head of the team. His traces were fastened, the sled broken out, and w ith both men running they dashed out on to the river trail. Highly as the dogdriver had forevalued Buc k, w ith his two devils, he found, while the day was yet young, that he had undervalued. At a bound Buc k took up the duties of leadership。s heels, and w ho never put an ounce more of his weight against the breastband than he was pelled to do, was swiftly and repeatedly shaken for loaf
