Later on, in the fall of the year, he saved John Thornton's life in quite another fashion.The three partners were lining a long and narrow poling-boat down a bad stretch of rapids on the Forty- Mile Creek.Hans and Pete moved along the bank, snubbing with a thin Manila rope from tree to tree, while Thornton remained in the boat, helping its descent by means of a pole, and shouting directions to the shore.Buck, on the bank, worried and anxious, kept abreast of the boat, his eyes never off his master.
At a particularly bad spot, where a ledge of barely submerged rocks jutted out into the river, Hans cast off the rope, and, while Thornton poled the boat out into the stream, ran down the bank with the end in his hand to snub the boat when it had cleared the ledge.This it did, and was flying down-stream in a current as swift as a mill-race, when Hans checked it with the rope and checked too suddenly.The boat flirted over and snubbed in to the bank bottom up, while Thornton, flung sheer out of it, was carried down-stream toward the worst part of the rapids, a stretch of wild water in which no swimmer could live.
Buck had sprung in on the instant; and at the end of three hundred yards, amid a mad swirl of water, he overhauled Thornton.When he felt him grasp his tail, Buck headed for the bank, swimming with all his splendid strength.But the progress shoreward was slow; the progress down-stream amazingly rapid.From below came the fatal roaring where the wild current went wilder and was rent in shreds and spray by the rocks which thrust through like the teeth of an enormous comb.The suck of the water as it took the beginning of the last steep pitch was frightful, and Thornton knew that the shore was impossible.He scraped furiously over a rock, bruised across a second, and struck a third with crushing force.He clutched its slippery top with both hands, releasing Buck, and above the roar of the churning water shouted: "Go, Buck! Go!"Buck could not hold his own, and swept on down-stream, struggling desperately, but unable to win back.When he heard Thornton's command repeated, he partly reared out of the water, throwing his head high, as though for a last look, then turned obediently toward the bank.He swam powerfully and was dragged ashore by Pete and Hans at the very point where swimming ceased to be possible and destruction began.
They knew that the time a man could cling to a slippery rock in the face of that driving current was a matter of minutes, and they ran as fast as they could up the bank to a point far above where Thornton was hanging on.They attached the line with which they had been snubbing the boat to Buck's neck and shoulders, being careful that it should neither strangle him nor impede his swimming, and launched him into the stream.He struck out boldly, but not straight enough into the stream.He discovered the mistake too late, when Thornton was abreast of him and a bare half-dozen strokes away while he was being carried helplessly past.
Hans promptly snubbed with the rope, as though Buck were a boat.The rope thus tightening on him in the sweep of the current, he was jerked under the surface, and under the surface he remained till his body struck against the bank and he was hauled out.He was half drowned, and Hans and Pete threw themselves upon him, pounding the breath into him and the water out of him.He staggered to his feet and fell down.The faint sound of Thornton's voice came to them, and though they could not make out the words of it, they knew that he was in his extremity.His master's voice acted on Buck like an electric shock, He sprang to his feet and ran up the bank ahead of the men to the point of his previous departure.
Again the rope was attached and he was launched, and again he struck out, but this time straight into the stream.He had miscalculated once, but he would not be guilty of it a second time.Hans paid out the rope, permitting no slack, while Pete kept it clear of coils.Buck held on till he was on a line straight above Thornton; then he turned, and with the speed of an express train headed down upon him.Thornton saw him coming, and, as Buck struck him like a battering ram, with the whole force of the current behind him, he reached up and closed with both arms around the shaggy neck.Hans snubbed the rope around the tree, and Buck and Thornton were jerked under the water.Strangling, suffocating, sometimes one uppermost and sometimes the other, dragging over the jagged bottom, smashing against rocks and snags, they veered in to the bank.
Thornton came to, belly downward and being violently propelled back and forth across a drift log by Hans and Pete.His first glance was for Buck, over whose limp and apparently lifeless body Nig was setting up a howl, while Skeet was licking the wet face and closed eyes.Thornton was himself bruised and battered, and he went carefully over Buck's body, when he had been brought around, finding three broken ribs.
"That settles it," he announced."We camp right here." And camp they did, till Buck's ribs knitted and he was able to travel.
That winter, at Dawson, Buck performed another exploit, not so heroic, perhaps, but one that put his name many notches higher on the totem-pole of Alaskan fame.This exploit was particularly gratifying to the three men; for they stood in need of the outfit which it furnished, and were enabled to make a long-desired trip into the virgin East, where miners had not yet appeared.It was brought about by a conversation in the Eldorado Saloon, in which men waxed boastful of their favorite dogs.Buck, because of his record, was the target for these men, and Thornton was driven stoutly to defend him.At the end of half an hour one man stated that his dog could start a sled with five hundred pounds and walk off with it; a second bragged six hundred for his dog; and a third, seven hundred.
"Pooh! pooh!" said John Thornton; "Buck can start a thousand pounds.""And break it out? and walk off with it for a hundred yards?" demanded Matthewson, a Bonanza King, he of the seven hundred vaunt.
