But Snowbird only heard the soft glide of the wolves in the snow. The wind was blowing toward Dan; and while he had heard the loud chorus of the pack, one of the most far-carrying cries, and the penetrating crack of a pistol, she couldn't hear his answering shout. In fact, the wilderness seemed preternaturally still. All was breathless, heavy with suspense, and she stood, just as Dan had thought, between the ruin of her fire and the sled, and she looked with straight eyes to the oncoming wolves. "Hurry, Snowbird," Lennox was whispering. "Give me the pistol--for that last work. We have only a moment more." He looked very calm and brave, half-raised as he was on the sled, and perhaps a half-smile lingered at his bearded lips. And the bravest thing of all was that to spare her, he was willing to take the little weapon from her hand to use it in its last service. She tried to smile at him, then crept over to his side. The strain was over. They knew what they had to face. She put the pistol in his steady hand. His hand lowered to his side and he sat waiting. The moments passed. The wolves seemed to be waiting too, for the last flickering tongue of the little fire to die away. The last of her fuel was ignited and burning out; they were crouched and ready to spring if she should venture forth after more. The darkness closed down deeper, and at last only a column of smoke remained. It was nothing to be afraid of. The great, gray leader of the pack, a wolf that weighed nearly one hundred pounds, began slowly and deliberately to set his muscles for the spring. It was the same as when the great bull elk comes to bay at the base of the cliffs: usually some one wolf, often the great pack leader, wishing to remind his followers of his might, or else some full-grown male proud in his strength, will attack alone. Because this was the noblest game that the pack had ever faced, the leader chose to make the first leap himself. It was true that these two had neither such horns nor razor-edged hoofs as the elk, yet they had eyes that chilled his heart when he tried to look at them. But one was lying almost prone, and the fire was out. Besides, the madness of starvation, intensified ten times by their terrible realization of the wound at her hip, was upon the pack as never before. The muscles bunched at his lean flanks. But as Snowbird and her father gazed at him in fascinated horror, the great wolf suddenly smashed down in the snow. She was aware of its curious, utter collapse actually before the sound of the rifle shot that occasioned it had penetrated her consciousness. It was a perfect shot at long range; and for a long instant her tortured faculties refused to accept the truth.
