But behind him was Dave, likewise straining backward, and behind the sled was François, pulling till his tendons cracked.

Again, the rim ice broke away before and behind, and there was no escape except up the cliff. Perrault scaled it by a miracle, while François prayed for just that miracle; and with every thong and sled-lashing and the last bit of harness rove into a long rope, the dogs were hoisted, one by one, to the cliff crest. François came up last, after the sled and load. Then came the search for a place to descend, which descent was ultimately made by the aid of the rope, and night found them back on the river with a quarter of a mile to the day’s credit.

By the time they made the Houtalinqua and good ice, Buck was played out. The rest of the dogs were in like condition; but Perrault, to make up lost time, pushed them late and early. The first day they covered thirty-five miles to the Big Salmon; the next day thirty-five more to the Little Salmon; the third day forty miles, which brought them well up toward the Five Fingers.

Buck’s feet were not so compact and hard as the feet of the huskies. His had softened during the many generations since the day his last wild ancestor was tamed by a cave-dweller or river man. All day long he limped in agony, and camp once made, lay down like a dead dog. Hungry as he was, he would not move to receive his ration of fish, which François had to bring to him. Also, the dog-driver rubbed Buck’s feet for half an hour each night after supper, and sacrificed the tops of his own moccasins to make four moccasins for Buck. This was a great relief, and Buck caused even the weazened face of Perrault to twist itself into a grin one morning, when François forgot the moccasins and Buck lay on his back, his four feet waving appealingly in the air, and refused to budge without them. Later his feet grew hard to the trail, and the worn-out footgear was thrown away.

At the Pelly one morning, as they were harnessing up, Dolly, who had never been conspicuous for anything, went suddenly mad. She announced her condition by a long, heart-breaking wolf howl that sent every dog bristling with fear, then sprang straight for Buck. He had never seen a dog go mad, nor did he have any reason to fear madness; yet he knew that here was horror, and fled away from it in panic. Straight away he raced, with Dolly, panting and frothing, one leap behind; nor could she gain on him, so great was his terror, nor could he leave her, so great was her madness. He plunged through the wooded breast of the island, flew down to the lower end, crossed a back channel filled with rough ice to another island, gained a third island, curved back to the main river, and in desperation started to cross it. And all the time, though he did not look, he could hear her snarling just one leap behind. François called to him a quarter of a mile away and he doubled back, still one leap ahead, gasping painfully for air and putting all his faith in that François would save him. The dog-driver held the axe poised in his hand, and as Buck shot past him the axe crashed down upon mad Dolly’s head.

Buck staggered over against the sled, exhausted, sobbing for breath, helpless. This was Spitz’s opportunity. He sprang upon Buck, and twice his teeth sank into his unresisting foe and ripped and tore the flesh to the bone. Then François’s lash descended, and Buck had the satisfaction of watching Spitz receive the worst whipping as yet administered to any of the team.

“One devil, dat Spitz,” remarked Perrault. “Some dam day heem keel dat Buck.”

“Dat Buck two devils,” was François’s rejoinder. “All de tam I watch dat Buck I know for sure. Lissen: some dam fine day heem get mad lak hell an’ den heem chew dat Spitz all up an’ spit heem out on de snow. Sure. I know.”

From then on it was war between them. Spitz, as lead-dog and acknowledged master of the team, felt his supremacy threatened by this strange Southland dog. And strange Buck was to him, for of the many Southland dogs he had known, not one had shown up worthily in camp and on the trail. They were all too soft, dying under the toil, the frost, and starvation. Buck was the exception. He alone endured and prospered, matching the husky in strength, savagery, and cunning. Then he was a masterful dog, and what made him dangerous was the fact that the club of the man in the red sweater had knocked all
