Half an hour later the Scotchman gave the order, "Mush!" He was off again, this time on the back trail as far as the Narrows, from which point he meant to strike across to intersect the fork of the road leading to the divide.
The storm had passed and when the late sun rose it was in a blue sky. Fine enough the day was overhead, but the slushy snow, where it was worn thin on the river by the sweep of the wind, made heavy travel for the dogs. Macdonald was glad enough to reach the Narrows, where he could turn from the river and cut across to hit the trail of the men he was following. He had about five miles to go before he would reach the Smith Crossing road and every foot of it he would have to break trail for the dogs. This was slow business, since he had no partner at the gee-pole. Back and forth, back and forth he trudged, beating down the loose snow for the runners. It was a hill trail, and the drifts were in most places not very deep. But the Scotchman was doing the work of two, and at a killing pace.
Over a ridge the team plunged down into a little park where the snow was deeper. Macdonald, breaking trail across the mountain valley, found his feet weighted with packed ice slush so that he could hardly move them. When at last he had beaten down a path for his dogs he stood breathing deep at the summit of the slope. Before him lay the main road to Smith's Crossing, scarce fifty yards away. He gave a deep whoop of triumph, for along it ran the wavering tracks left by a sled. He was on the heels of his enemy at last.
As he turned back to his Siberian hounds, the eyes of Macdonald came to abrupt attention. On the hillside, not ten yards from him, something stuck out of the snow like a signpost. It was the foot of a man.
Slowly Macdonald moved toward it. He knew well enough what he had stumbled across—one of the tragedies that in the North are likely to be found in the wake of every widespread blizzard. Some unfortunate traveler, blinded by the white swirl, had wandered from the trail and had staggered up a draw to his death.
With a little digging the Alaskan uncovered a leg. The man had died where he had fallen, face down. Macdonald scooped away the snow and found a pack strapped to the back of the buried man. He cut the thongs and tried to ease it away. But the gunnysack had frozen to the parka. When he pulled, the rotten sacking gave way under the strain. The contents of the pack spilled out.
The eyes in the grim face of Macdonald grew hard and steely. He had found, by some strange freak of chance, much more than he had expected, to find. Using his snowshoe as a shovel, he dug the body free and turned it over. At sight of the face he gave a cry of astonishment.
