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.

Then the rifle spoke again, and a second wolf—a large male that crouched on the other side of the sled—fell kicking in the snow. The pack had leaped forward at the first death; but they halted at the second. And then terror came to them when the third wolf suddenly opened its savage lips and screamed in the death agony.

Up to this time, except for the report of the rifle, the attack had been made in utter silence. The reason was just that both breath and nervous force are needed to shout; and Dan Failing could afford to waste neither of these vital forces. He had dropped to his knee, and was firing again and again, his gray eyes looking clear and straight along the barrel, his fingers without jerk or tremor pressing again and again at the trigger, his hands holding the rifle as in a vice. Every nerve and muscle were completely in his command. The distance was far, yet he shot with deadly, amazing accuracy. The wolves were within a few feet of the girl, and a fraction's waver in the gun barrel might have sped his bullet toward her.

"It's Dan Failing," Lennox shouted as the fourth wolf died.

Then Snowbird snatched her pistol from her father's hand and opened fire. The two shells were no longer needed to free herself and her father from the agony of fangs. She took careful aim, and although a pistol is never as accurate or as powerful as a rifle, she killed one wolf and wounded another.

Frenzied in their savagery, three or four of the remaining wolves leaped at the body of one of the wounded; but the others scattered in all directions. Still Dan fired with the same unbelievable accuracy, and still the wolves died in the snow. The girl and the man were screaming now in the frenzied joy of deliverance. The wolves scurried frantically among the trees; and some of them unknowingly ran full in the face of their enemy, to be shot down without mercy. And few indeed were those that escaped,—to collect on a distant ridge, and, perhaps, to be haunted in dreams by a Death that came out of the shadows to blast the pack.
