And if the game should turn hunter and the man turn hunted! The trapper speeds down the snowy slope, striding, sliding, coasting, vaulting over hummocks of snow, glissading down the drifts, leaping rather than running. The frosty air acts as a conductor to sound, and the frost films come in stings against the face of the man whose eye, ear, and touch are strained for danger. It is the dog that catches the first breath of peril, uttering a smothered "_woo! woo!_" The trapper tries to persuade himself the alarm was only the far scream of a wolf-hunted lynx; but it comes again, deep and faint, like an echo in a dome. One glance over his shoulder shows him black forms on the snow-crest against the sky. He has been tricked again, and knows how the fox feels before the dogs in full cry. The trapper is no longer a man. He is a hunted thing with terror crazing his blood and the sleuth-hounds of the wilds on his trail. Something goes wrong with his snow-shoe. Stooping to right the slip-strings, he sees that the dog's feet have been cut by the snow crust and are bleeding. It is life for life now; the old, hard, inexorable Mosaic law, that has no new dispensation in the northern wilderness, and demands that a beast's life shall not sacrifice a man's. One blow of his gun and the dog is dead. The far, faint howl has deepened to a loud, exultant bay. The wolf-pack are in full cry. The man has rounded the open alley between the trees and is speeding down the hillside winged with fear. He hears the pack pause where the dog fell. That gives him respite. The moon is behind, and the man-shadow flits before on the snow like an enemy heading him back. The deep bay comes again, hard, metallic, resonant, nearer! He feels the snow-shoe slipping, but dare not pause. A great drift thrusts across his way and the shadow in front runs slower. They are gaining on him. He hardly knows whether the crunch of snow and pantings for breath are his own or his pursuers'. At the crest of the drift he braces himself and goes to the bottom with the swiftness of a sled on a slide. The slant moonlight throws another shadow on the snow at his heels. It is the leader of the pack. The man turns, and tosses up his arms--an Indian trick to stop pursuit. Then he fires. The ravening hunter of man that has been ambushing him half the day rolls over with a piercing howl. The man is off and away. If he only had the quick rifle, with which white men and a body-guard of guides hunt down a single quarry, he would be safe enough now. But the old musket is slow loading, and speed will serve him better than another shot.
