Reckless at least of this peril, the dogs would have leaped forward to close with the invaders but their master intervened. The stinging, cracking lash in his hand drove them from the foe. Their overlord, man, elected to make the battle alone. In two springs he reached the sledge, tore the rifle from its coverings, and was at the side of the girl. He thrust the weapon into her hands. "Back, lady; back to the sledge!" he cried. "Unless I call, shoot not. If you do shoot, aim for the throat when they rear, and leave the rest to me and the dogs. Many times have I met these enemies, and I know well how to deal with them." With another crack of the whip over the heads of the snarling pack, he left her and bounded forward, spear in hand and long knife bared. Awkward of pace and unhurried, the snow kings came on to their feast. In a thought the man chose his ground. Between him and the bears the ridge narrowed so that for a few feet there was footway for but one of the monsters at once. Polaris ran to where that narrow path began and threw himself on his face on the ice. At that ruse the foremost bear hesitated. He reared and brushed his muzzle with his formidable crescent-clawed paw. Polaris might have shot then and ended at once the hardest part of his battle. But the man held to a stubborn pride in his own weapons. Both of the beasts he would slay, if he might, as he always had slain. His guns were reserved for dire extremity. The bear settled to all fours again, and reached out a cautious paw and felt along the path, its claws gouging seams in the ice. Assured that the footing would hold, it crept out on the narrow way, nearer and nearer to the motionless man. Scarce a yard from him it squatted. The steam of its breath beat toward him. It raised one armed paw to strike. The girl cried out in terror and raised the rifle. The man moved, and she hesitated. Down came the terrible paw, its curved claws projected and compressed for the blow. It struck only the adamantine ice of the pathway, splintering it. With the down-stroke timed to the second, the man had leaped up and forward. As though set on a steel spring, he vaulted into the air, above the clashing talons and gnashing jaws, and landed light and sure on the back of his ponderous adversary. To pass an arm under the bear's throat, to clip its back with the grip of his legs was the work of a heart-beat's time for Polaris. With a stifled howl of rage the bear rose to its haunches, and the man rose with it. He gave it no time to turn or settle. Exerting his muscles of steel, he tugged the huge head back. He swung clear from the body of his foe. His feet touched the path and held it. He shot one knee into the back of the bear.
