On the smooth stretch of ice beside the trading post at Sixty Mile, Smoke overtook two more sleds. All had just changed teams, and for five minutes they ran abreast, each man on his knees and pouring whip and voice into the maddened dogs. But Smoke had studied out that portion of the trail, and now marked the tall pine on the bank that showed faintly in the light of the many fires. Below that pine was not merely darkness, but an abrupt cessation of the smooth stretch. There the trail, he knew, narrowed to a single sled-width. Leaning out ahead, he caught the haul-rope and drew his leaping sled up to the wheel-dog. He caught the animal by the hind-legs and threw it. With a snarl of rage it tried to slash him with its fangs, but was dragged on by the rest of the team. Its body proved an efficient brake, and the two other teams, still abreast, dashed ahead into the darkness for the narrow way. Smoke heard the crash and uproar of their collision, released his wheeler, sprang to the gee-pole, and urged his team to the right into the soft snow where the straining animals wallowed to their necks. It was exhausting work, but he won by the tangled teams and gained the hard-packed trail beyond. VI. On the relay out of Sixty Mile, Smoke had next to his poorest team, and though the going was good, he had set it a short fifteen miles. Two more teams would bring him in to Dawson and to the Gold-Recorder's office, and Smoke had selected his best animals for the last two stretches. Sitka Charley himself waited with the eight Malemutes that would jerk Smoke along for twenty miles, and for the finish, with a fifteen-mile run, was his own team--the team he had had all winter and which had been with him in the search for Surprise Lake.
