At the first corner, beside Smoke's stake, Von Schroeder placed his. The mallets struck at the same instant. As they hammered, more arrived from behind and with such impetuosity as to get in one another's way and cause jostling and shoving. Squirming through the press and calling his name to the policeman, Smoke saw the Baron, struck in collision by one of the rushers, hurled clean off his feet into the snow. But Smoke did not wait. Others were still ahead of him. By the light of the vanishing fire, he was certain that he saw the back, hugely looming, of Big Olaf, and at the southwestern corner Big Olaf and he drove their stakes side by side. It was no light work, this preliminary obstacle race. The boundaries of the claim totalled nearly a mile, and most of it was over the uneven surface of a snow-covered, niggerhead flat. All about Smoke men tripped and fell, and several times he pitched forward himself, jarringly, on hands and knees. Once, Big Olaf fell so immediately in front of him as to bring him down on top. The upper center-stake was driven by the edge of the bank, and down the bank the racers plunged, across the frozen creek-bed, and up the other side. Here, as Smoke clambered, a hand gripped his ankle and jerked him back. In the flickering light of a distant fire, it was impossible to see who had played the trick. But Arizona Bill, who had been treated similarly, rose to his feet and drove his fist with a crunch into the offender's face. Smoke saw and heard as he was scrambling to his feet, but before he could make another lunge for the bank a fist dropped him half-stunned into the snow. He staggered up, located the man, half-swung a hook for his jaw, then remembered Shorty's warning and refrained. The next moment, struck below the knees by a hurtling body, he went down again. It was a foretaste of what would happen when the men reached their sleds. Men were pouring over the other bank and piling into the jam. They swarmed up the bank in bunches, and in bunches were dragged back by their impatient fellows. More blows were struck, curses rose from the panting chests of those who still had wind to spare, and Smoke, curiously visioning the face of Joy Gastell, hoped that the mallets would not be brought into play. Overthrown, trod upon, groping in the snow for his lost stakes, he at last crawled out of the crush and attacked the bank farther along. Others were doing this, and it was his luck to have many men in advance of him in the race for the northwestern corner.
