It was inevitable that they should go short on dog food. But they hastened it by overfeeding, bringing the day nearer when underfeeding would commence. The Outsider dogs whose digestions had not been trained by chronic famine to make the most of little, had voracious appetites. And when, in addition to this, the worn-out huskies pulled weakly, Hal decided that the orthodox ration was too small. He doubled it. And to cap it all, when Mercedes, with tears in her pretty eyes and a quaver in her throat, could not cajole him into giving the dogs still more, she stole from the fish-sacks and fed them slyly. But is was not food that Buck and the huskies needed, but rest. And though they were making poor time, the heavy load they dragged sapped their strength severely.
Then came the underfeeding. Hal awoke one day to the fact that his dog food was half-gone and the distance only quarter covered; further, that for love or money no additional dog food was to be obtained. So he cut down even the orthodox ration and tried to increase the day's travel. His sister and brother-in-law seconded him; but they were frustrated by their heavy outfit and their own incompetence. It was a simple matter to give the dogs less food; but it was impossible to make the dogs travel faster, while their own inability to get under way earlier in the morning prevented them from traveling longer hours. Not only did they not know how to work dogs, but they did not know how to work themselves.
The first to go was Dub. Poor blundering thief that he was, always getting caught and punished, he had none the less been a faithful worker. His wrenched shoulder-blade, untreated and unrested, went from bad to worse, till finally Hal shot him with the big Colt's revolver. It is a saying of the country that an Outside dog starves to death on the ration of the husky, so the six Outside dogs under Buck could do no less than die on half the ration of the husky. The Newfoundland went first, followed by the three short-haired pointers, the two mongrels hanging more grittily on to life, but going in the end....
As it was with Buck, so was it with his mates. They were perambulating skeletons. There were seven all together, including him. In their very great misery they had become insensible to the bite of the lash or the bruise of the club. The pain of the beating was dull and distant, just as the things their eyes saw and their ears heard seemed dull and distant. They were not half-living, or quarter-living. They were simply so many bags of bones in which sparks of life fluttered faintly. When a halt was made, they dropped down in the traces like dead dogs, and the spark dimmed and paled and seemed to go out. And when the club or whip fell upon them, the spark fluttered feebly up, and they tottered to their feet and staggered on.
There came a day when Billee, the good-natured, fell and could not rise. Hal had traded off his revolver, so he took the axe and knocked Billee on the head as he lay in the traces, then cut the carcass out of the harness and dragged it to one side. Buck saw, and his mates saw, and they knew that this thing was very close to them. On the next day Koona went, and but five of them remained: Joe, too far gone to be malignant; Pike, crippled and limping, only half-conscious and not conscious enough longer to malinger; Sol-leks, the one-eyed, still faithful to the toil of trace and trail, and mournful in that he had so little strength with which to pull; Teek, who had not traveled so far that winter and who was now beaten more than the others because he was fresher; and Buck, still at the head of the team, but no longer enforcing discipline or striving to enforce it, blind with weakness half the time and keeping the trail by the loom of it and by the dim feel of his feet....
But the team did not get up at the command. It had long since passed into the stage where blows were required to rouse it. The whip flashed out, here and there, on its merciless errands. John Thornton compressed his lips. Sol-leks was the first to crawl to his feet. Teek followed. Joe came next, yelping with pain. Pike made painful efforts. Twice he fell over, when half-up, and on the third attempt managed to rise. Buck made no effort. He lay quietly where he had fallen. The lash bit into him again and again, but he neither whined nor struggled. Several times Thornton started, as though to speak, but changed his mind. A moisture came into his eyes, and, as the whipping continued, he arose and walked irresolutely up and down.
This was the first time Buck had failed, in itself a sufficient reason to drive Hal into a rage. He exchanged the whip for the customary club. Buck refused to move under the rain of heavier blows which now fell upon him. Like his mates, he was barely able to get up, but, unlike them, He had made up his mind not to get up. He had a vague feeling of impending doom. This had been strong upon him when he pulled into the bank, and it had not departed from him. What of the thin and rotten ice he had felt under his feet all day, it seemed that he sensed disaster close at hand, out there ahead on the ice where his master was trying to drive him. He refused to stir. So greatly had he suffered, and so far gone was he, that the blows did not hurt much. And as they continued to fall upon him, the spark of life within flickered and went down. It was nearly out. He felt strangely numb. As though from a great distance, he was aware that he was being beaten. The last sensations of pain left him. He no longer felt anything, though very faintly he could hear the impact of the club upon his body. But it was no longer his body, it seemed so far away.
And then, suddenly, without warning, uttering a cry that was inarticulate and more like the cry of an animal, John Thornton sprang upon the man who wielded the club. Hal was hurled backward, as though struck by a falling tree. Mercedes screamed. Charles looked on wistfully, wiped his watery eyes, but did not get up because of his stiffness.
John Thornton stood over Buck, struggling to control himself, too convulsed with rage to speak.
"If you strike that dog again, I'll kill you," he at last managed to say in a choking voice.
"It's my dog," Hal replied, wiping the blood from his mouth as he came back. "Get out of my way, or I'll fix you. I'm going to Dawson."
Thornton stood between him and Buck and evinced no intention of getting out of the way. Hal drew his long hunting knife. Mercedes screamed, cried, laughed, and manifested the chaotic abandonment of hysteria. Thornton rapped Hal's knuckles with the axe-handle, knocking the knife to the ground. He rapped his knuckles again as he tried to pick it up. Then he stooped, picked it up himself, and with two strokes cut Buck's traces.
Hal had no fight left in him. Besides, his hands were full with his sister, or his arms, rather; while Buck was too near dead to be of further use in hauling the sled. A few minutes later they pulled out from the bank and down the river. Buck heard them go and raised his head to see. Pike was leading, Sol-leks was at the wheel, and between were Joe and Teek. They were limping and staggering. Mercedes was riding the loaded sled. Hal guided at the gee-pole, and Charles stumbled along in the rear.
As Buck watched them, Thornton knelt beside him and with rough, kindly hands searched for broken bones. By the time his search had disclosed nothing more than many bruises and a state of terrible starvation, the sled was a quarter of a mile away. Dog and man watched it crawling along over the ice. Suddenly, they saw its back end drop down, as into a rut, and the gee-pole, with Hal clinging to it, jerk into the air. Mercedes' scream came to their ears. They saw Charles turn one step to run back, Sand then a whole section of ice give way and dogs and humans disappear. A yawning hole was all that was to be seen. The bottom had dropped out of the trail.
"You poor devil," said John Thornton and Buck licked his hand."
