The gray circle about the fire was growing impatient. Snowbird waited to the last instant before she admitted this fact. But it is possible only so long to deny the truth of a thing that all the senses verify, and that moment for her was past.

At first the wolves had lingered in the deepest shadow and were only visible in profile against the gray snow. But as the night wore on, they became increasingly careless. They crept up to the very edge of the little circle of firelight; and when a high-leaping flame threw a gleam over them, they didn't shrink. She had only to look up to see that age-old circle of fire—bright dots, two and two—at every side.

It is an instinct in the hunting creatures to remain silent before the attack. The triumph cries come afterward. But they seemed no longer anxious about this, either. Sometimes she would hear their footfall as they leaped in the snow, and what excitement stirred them she didn't dare to think. Quite often one of them would snarl softly,—a strange sound in the darkness.

She noticed that when she went to her hands and knees, laboriously to cut a piece of the drier wood from the rain-soaked, rotted snag that was her principal supply of fuel, every wolf would leap forward, only to draw back when she stood straight again. At such times she saw them perfectly plainly,—their gaunt bodies, their eyes lighted with the insanity of famine, their ivory fangs that glistened in the firelight. She worked desperately to keep the fire burning bright. She dared not neglect it for a moment. Except for the single pistol ball that she could afford to expend on the wolves—of the three she had—the fire was her last defense.

But it was a losing fight. The rain-soaked wood smoked without flame, the comparatively dry core with which Dan had started the fire had burned down, and the green wood, hacked with such heart-breaking difficulty from the saplings that Dan had cut, needed the most tireless attention to burn at all.

When Dan had gone, these little trees were well within the circle of the wolves. Unfortunately, the circle had drawn in past them. Nevertheless, now that the last of the drier dead wood was consumed, she shouldered her ax and walked straight toward the gray, crouching bodies in the snow. For a tragic second she thought that the nearest of them was going to stand its ground. But almost when she was in striking range, and its body was sinking to the snow in preparation for a leap, it skulked back into the shadow. Exhausted as she was, it seemed to her that she chopped endlessly to cut away one little length. The ax blade was dull, the handle awkward in her hand, she could scarcely stand on her broken snowshoes, and worse, the ice crust broke beneath her blows, burying the sapling in the snow. She noticed that every time she bent to strike a blow, the circle would plunge a step nearer her, withdrawing as she straightened again.

Books of woodcraft often describe with what ease a fire may be built and maintained in wet snow. It works fairly well in theory, but it is a heart-breaking task in practice. Under such difficulties as she worked, it became one of those dreadful undertakings that partake of a nightmare quality,—the walking of a treadmill or the sweeping of waves from the shore.

When she secured the first length, her fire was almost extinguished. It threw a fault cloud of smoke into the air, but the flame was almost gone. The darkness dropped about her, and the wolves came stealing over the snow. She worked furiously, with the strength of desperation, and little by little she won back a tiny flame.

Her nervous vitality was flowing from her in a frightful stream. Too long she had toiled without food in the constant presence of danger, and she was very near indeed to utter exhaustion. But at the same time she knew she must not faint. That was one thing she could not do,—to fall unconscious before the last of her three cartridges was expended in the right way.

Again she went forth to the sapling, and this time it seemed to her that if she simply tossed the ax through the air, she could fell one of the gray crowd. But when she stooped to pick it up—She didn't finish the thought. She turned to coax the fire. And then she leaned sobbing over the sled.

"What's the use?" she cried. "He won't come back. What's the use of fighting any more?"

"There's always use of fighting," her father told her. He seemed to speak with difficulty, and his face looked strange and white. The cold and the exposure were having their effect on his weakened system, and unconsciousness was a near shadow indeed. "But, dearest,—if I could only make you do what I want you to—"

"What?"

"You're able to climb a tree, and if you'd take these coats, you wouldn't freeze by morning. If you'd only have the strength—"

"And see you torn to pieces!"

"I'm old, dear—and very tired—and I'd crawl away into the shadows, where you couldn't see. There's no use mincing words, Snowbird. You're a brave girl—always have been since a little thing, as God is my Judge—and you know we must face the truth. Better one of us die than both. And I promise—I'll never feel their fangs. And I won't take your pistol with me either."

Her thought flashed to the clasp hunting knife that he carried in his pocket. But her eyes lighted, and she bent and kissed him. And the wolves leaped forward even at this.

"We'll stay it out," she told him. "We'll fight it to the last—just as Dan would want us to do. Besides—it would only mean the same fate for me, in a little while. I couldn't cling up there forever—and Dan won't come back."

She was wholly unable to gain on the fire. Only by dint of the most heart-breaking toil was she able to secure any dry fuel for it at all. Every length of wood she cut had to be scraped of bark, and half the time the fire was only a sickly column of white smoke. It became increasingly difficult to swing the ax. The trail was almost at its end.

The after-midnight hours drew one by one across the face of the wilderness, and she thought that the deepening cold presaged dawn. Her fingers were numb. Her nerve control was breaking; she could no longer drive a straight blow with the ax. The number of the wolves seemed to be increasing: every way she looked she could see them leaping. Or was this just hysteria? Surely the battle could go on but a few moments more. The wolves themselves, sensing dawn, were losing the last of their cowardice.

Once more she went to one of the saplings, but she stumbled and almost went to her face at the first blow. It was the instant that her gray watchers had been waiting for. The wolf that stood nearest leaped—a gray streak out of the shadow—and every wolf in the pack shot forward with a yell. It was a short, expectant cry; but it chopped off short. For with a half-sob, and seemingly without mental process, she aimed her pistol and fired.

A fast-leaping wolf is one of the most difficult pistol targets that can be imagined. It bordered on the miraculous that she did not miss him altogether. Her nerves were torn, their control over her muscles largely gone. Yet the bullet coursed down through the lungs, inflicting a mortal wound.

The wolf had leaped for her throat; but he fell short. She staggered from a blow, and she heard a curious sound in the region of her hip. But she didn't know that the fangs had gone home in her soft flesh. The wolf rolled on the ground; and if her pistol had possessed the shocking power of a rifle, he would have never got up again. As it was, he shrieked once, then sped off in the darkness to die. Five or six of the nearest wolves, catching the smell of his blood, bayed and sped after him.

But the remainder of the great pack—fully fifteen of the gray, gaunt creatures—came stealing across the snow toward her. White fangs had gone home; and a new madness was in the air.

Straining into the silence, a perfectly straight line between Cranston's camp and Snowbird's, Dan Failing came mushing across the snow. His sense of direction had never been obliged to stand such a test as this before. Snowbird's fire was a single dot on a vast plateau; yet he had gone straight toward it.

He was risking everything for the sake of speed. He gave no heed to the fallen timber that might have torn the web of his snowshoes to shreds. Because he shut out all thought of it, he had no feeling of fatigue. The fight with Cranston had been a frightful strain on muscle and nerve; but he scarcely remembered it now. His whole purpose was to return to Snowbird before the wolves lost the last of their cowardice.

The jerked venison that he had munched had brought him back much of his strength. He was wholly unconscious of his heavy pack. Never did he glide so swiftly, so softly, with such unerring step; and it was nothing more or less than a perfect expression of the ironclad control that his steel nerves had over his muscles.

Then, through the silence, he heard the shout of the pack as the wolf had leaped at Snowbird. He knew what it meant. The wolves were attacking then, and a great flood of black, hating bitterness poured over him at the thought he had been too late. It had all been in vain, and before the thought could fully go home, he heard the dim, far-off crack of a pistol.

Was that the first of the three shots, the one she might expend on the wolves, or had the first two already been spent and was she taking the last gateway of escape? Perhaps even now Lennox was lying still on the sled, and she was standing before the ruin of her fire, praying that her soul might have wings. He shouted with all the power of his lungs across the snow.

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.

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.

Again the pack-song would be despairing and strange in the winter nights,—that age-old chant of Famine and Fear and the long war of existence with only Death and Darkness in the end. And because it is the voice of the wilderness itself, the tenderfoot that camps in the evergreen forest will listen, and his talk will die at his lips, and he will have the beginnings of knowledge. And perhaps he will wonder if God has given him the thews and fiber to meet the wilderness breast to breast as Dan had met it: to remain and to fight and to conquer. And thereby his metal will be tested in the eyes of the Red Gods.

Snowbird stood waiting in the snow, arms stretched to her forester as Dan came running through the wood. But his arms were wider yet, and she went softly into them.

"We will take it easy from now on," Dan Failing told them, after the camp was cleared of its dead and the fire was built high. "We have plenty of food; and we will travel a little while each day and make warm camps at night. We'll have friendship fires, just as sometimes we used to build on the ridge."

"But after you get down into the valleys?" Lennox asked anxiously. "Are you and Snowbird coming up here to live?"

The silence fell over their camp; and a wounded wolf whined in the darkness. "Do you think I could leave it now?" Dan asked. By no gift of words could he have explained why; yet he knew that by token of his conquest, his spirit was wedded to the dark forests forever. "But heaven knows what I'll do for a living."

Snowbird crept near him, and her eyes shone in the bright firelight. "I've solved that," she said. "You know you studied forestry—and I told the supervisor at the station how much you knew about it. I wasn't going to tell you until—until certain things happened—and now they have happened, I can't wait another instant. He said that with a little more study you could get into the Forest Service—take an examination and become a ranger. You're a natural forester if one ever lived, and you'd love the work."

"Besides," Lennox added, "it would clip my Snowbird's wings to make her live on the plains. My big house will be rebuilt, children. There will be fires in the fireplace on the fall nights. There is no use of thinking of the plains."

"And there's going to be a smaller house—just a cottage at first—right beside it," Dan replied. He could go back to his forests, after all. He wouldn't have to throw away his birthright, fought for so hard; and it seemed to him no other occupation could offer so much as that of the forest rangers,—those silent, cool-nerved guardians of the forest and keepers of its keys.

For a long time Snowbird and he stood together at the edge of the firelight, their bodies warm from the glow, their hearts brimming with words they could not utter. Words always come hard to the mountain people. They are folk of action, and Dan, rather than to words, trusted to the yearning of his arms.

"We're made for each other, Snowbird darling," he told her breathlessly at last. "And at last I can claim what I've been waiting for all these months."

He claimed it; and in open defiance to all civil law, he collected fully one hundred times in the next few minutes. But it didn't particularly matter, and Snowbird didn't even turn her face. "Maybe you've forgotten you claimed it when you first came back too," she said.

So he had. It had completely slipped his mind, in the excitement of his fight with the wolf pack. And then while Lennox pretended to be asleep, they sat, breathless with happiness, on the edge of the sled and watched the dawn come out.

They had never seen the snow so lovely in the sunlight.
