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 Laberge. 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 François 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 François 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.

François was surprised, too, when they shot out in a tangle from the disrupted nest and he divined the cause of the trouble. “A-a-ah!” he cried to Buck. “Gif it to heem, by Gar! Gif it to heem, the dirty t’eef!”

Spitz was equally willing. He was crying with sheer rage and eagerness as he circled back and forth for a chance to spring in. Buck was no less eager, and no less cautious, as he likewise circled back and forth for the advantage. But it was then that the unexpected happened, the thing which projected their struggle for supremacy far into the future, past many a weary mile of trail and toil.

An oath from Perrault, the resounding impact of a club upon a bony frame, and a shrill yelp of pain heralded the breaking forth of pandemonium. The camp was suddenly discovered to be alive with skulking furry forms—starving huskies, four or five score of them, who had scented the camp from some Indian village. They had crept in while Buck and Spitz were fighting, and when the two men sprang among them with stout clubs they showed their teeth and fought back. They were crazed by the smell of the food. Perrault found one with head buried in the grub box. His club landed heavily on the gaunt ribs, and the grub box was capsized on the ground. On the instant a score of the famished brutes were scrambling for the bread and bacon. The clubs fell upon them unheeded. They yelped and howled under the rain of blows, but struggled none the less madly till the last crumb had been devoured.

In the meantime the astonished team dogs had burst out of their nests only to be set upon by the fierce invaders. Never had Buck seen such dogs. It seemed as through their bones would burst through their skins. They were mere skeletons, draped loosely in draggled hides, with blazing eyes and slavered fangs. But the hunger madness made them terrifying, irresistible.
