Dan Failing was never more thankful for his unerring sense of direction. He struck off at a forty-five-degree angle between their late course and a direct road to the river, and he kept it as if by a surveyor's line. All the old devices of the wilderness—the ridge on ridge that looked just alike, inclines that to the casual eye looked like downward slopes, streams that vanished beneath the snow, and the snow-mist blowing across the face of the landmarks—could not avail against him.

A half dozen of the wolves followed him at first. But perhaps their fierce eyes marked his long stride and his powerful body, and decided that their better chance was with the helpless man and the girl beside the flickering fire. They turned back, one by one. Dan kept straight on and in two hours crossed Cranston's trail.

It was perfectly plain in the moonlit snow. He began to back-track. He headed down a long slope and in an hour more struck the North Fork. He didn't doubt but that he would find Cranston in his camp, if he found the camp at all. The man had certainly returned to it immediately after setting fire to the buildings, if for no other reason than for food. It isn't well to be abroad on the wintry mountains without a supply of food; and Cranston would certainly know this fact.

Dan didn't know when a rifle bullet from some camp in the thickets would put an abrupt end to his advance. The brush grew high by the river, the elevation was considerably lower, and there might be one hundred camps out of the sight of the casual wayfarer. If Cranston should see him, mushing across the moonlit snow, it would give him the most savage joy to open fire upon him with his rifle.

Dan's advance became more cautious. He was in a notable trapping region, and he might encounter Cranston's camp at any moment. His keen eyes searched the thickets, and particularly they watched the sky line for a faint glare that might mean a camp fire. He tried to walk silently. It wasn't an easy thing to do with awkward snowshoes; but the river drowned the little noise that he made. He tried to take advantage of the shelter of the thickets and the trees. Then, at the base of a little ridge, he came to a sudden halt.

He had estimated just right. Not two hundred yards distant, a camp fire flickered and glowed in the shelter of a great log. He saw it, by the most astounding good fortune, through a little rift in the trees. Ten feet on either side, and it was obscured.

He lost no time. He did not know when the wolves about Snowbird's camp would lose the last of their cowardice. Yet he knew he must keep a tight grip on his self-control and not let the necessity of haste cost him his victory. He crept forward, step by step, placing his snowshoes with consummate care. When he was one hundred yards distant he saw that Cranston's camp was situated beside a little stream that flowed into the river and that—like the mountaineer he was—he had built a large lean-to reinforced with snowbanks. The fire burned at its opening. Cranston was not in sight; either he was absent from camp or asleep in his lean-to. The latter seemed the more likely.

Dan made a wide detour, coming in about thirty yards behind the construction. Still he moved with incredible caution. Never in his life had he possessed a greater mastery over his own nerves. His heart leaped somewhat fast in his breast; but this was the only wasted motion. It isn't easy to advance through such thickets without ever a misstep, without the rustle of a branch or the crack of a twig. Certain of the wild creatures find it easy; but men have forgotten how in too many centuries of cities and farms. It is hardly a human quality; and a spectator would have found a rather ghastly fascination in watching the lithe motions, the passionless face, the hands that didn't shake at all. But there were no spectators—unless the little band of wolves, stragglers from the pack that had gathered on the hills behind—watched with lighted eyes.

Dan went down at full length upon the snow and softly removed his snowshoes. They would be only an impediment in the close work that was sure to follow. He slid along the snow crust, clear to the mouth of the lean-to.

The moonlight poured through and showed the interior with rather remarkable plainness. Cranston was sprawled, half-sitting, half-lying on a tree-bough pallet near the rear wall. There was not the slightest doubt of the man's wakefulness. Dan heard him stir, and once—as if at the memory of his deed of the day before—he cursed in a savage whisper. Although he was facing the opening of the lean-to, he was wholly unaware of Dan's presence. The latter had thrust his head at the side of the opening, and it was in shadow. Cranston seemed to be watching the great, white snow fields that lay in front, and for a moment Dan was at loss to explain this seeming vigil. Then he understood. The white field before him was part of the long ridge that the three of them would pass on their way to the valleys. Cranston had evidently anticipated that the girl and the man would attempt to march out—even if he hadn't guessed they would try to take the helpless Lennox with them—and he wished to be prepared for emergencies. There might be sport to have with Dan, unarmed as he was. And his eyes were full of strange conjectures in regard to Snowbird. Both would be exhausted now and helpless—

Dan's eyes encompassed the room: the piles of provisions heaped against the wall, the snowshoes beside the pallet, but most of all he wished to locate Cranston's rifle. Success or failure hung on that. He couldn't find it at first. Then he saw the glitter of its barrel in the moonlight,—leaning against a grub-box possibly six feet from Cranston and ten from himself.

His heart leaped. The best he had hoped for—for the sake of Snowbird, not himself—was that he would be nearer to the gun than Cranston and would be able to seize it first. But conditions could be greatly worse than they were. If Cranston had actually had the weapon in his hands, the odds of battle would have been frightfully against Dan. It takes a certain length of time to seize, swing, and aim a rifle; and Dan felt that while he would be unable to reach it himself, Cranston could not procure it either, without giving Dan an opportunity to leap upon him. In all his dreams, through the months of preparation, he had pictured it thus. It was the test at last.

The gun might be loaded, and still—in these days of safety devices—unready to fire; and the loss of a fraction of a second might enable Cranston to reach his knife. Thus Dan felt justified in ignoring the gun altogether and trusting—as he had most desired—to a battle of hands. And he wanted both hands free when he made his attack.

If Dan had been erect upon his feet, his course would have been an immediate leap on the shoulders of his adversary, running the risk of Cranston reaching his hunting knife in time. But the second that he would require to get to his feet would entirely offset this advantage. Cranston could spring up too. So he did the next most disarming thing.

He sprang up and strode into the lean-to.

"Good evening, Cranston," he said pleasantly.

Cranston was also upon his feet the same instant. His instincts were entirely true. He knew if he leaped for his rifle, Dan would be upon his back in an instant, and he would have no chance to use it. His training, also, had been that of the hills, and his reflexes flung him erect upon his feet at the same instant that he saw the leap of his enemy's shadow. They brought up face to face. The rifle was now out of the running, as they were at about equal distances from it, and neither would have time to swing or aim it.

Dan's sudden appearance had been so utterly unlooked-for, that for a moment Cranston could find no answer. His eyes moved to the rifle, then to his belt where hung his hunting knife, that still lay on the pallet. "Good evening, Failing," he replied, trying his hardest to fall into that strange spirit of nonchalance with which brave men have so often met their adversaries, and which Dan had now. "I'm surprised to see you here. What do you want?"

Dan's voice when he replied was no more warm than the snow banks that reinforced the lean-to. "I want your rifle—also your snowshoes and your supplies of food. And I think I'll take your blankets, too."

"And I suppose you mean to fight for them?" Cranston asked. His lips drew up in a smile, but there was no smile in the tone of his words.

"You're right," Dan told him, and he stepped nearer. "Not only for that, Cranston. We're face to face at last—hands to hands. I've got a knife in my pocket, but I'm not even going to bring it out. It's hands to hands—you and I—until everything's square between us."

"Perhaps you've forgotten that day on the ridge?" Cranston asked. "You haven't any woman to save you this time."

"I remember the day, and that's part of the debt. The thing you did yesterday is part of it too. It's all to be settled at last, Cranston, and I don't believe I could spare you if you went to your knees before me. You've got a clearing out by the fire—big as a prize ring. We'll go out there—side by side. And hands to hands we'll settle all these debts we have between us—with no rules of fighting and no mercy in the end!"

They measured each other with their eyes. Once more Cranston's gaze stole to his rifle, but lunging out, Dan kicked it three feet farther into the shadows of the lean-to. Dan saw the dark face drawn with passion, the hands clenching, the shoulder muscles growing into hard knots. And Cranston looked and knew that merciless vengeance—that age-old sin and Christless creed by which he lived—had followed him down and was clutching him at last.

He saw it in the position of the stalwart form before him, the clear level eyes that the moonlight made bright as steel, the hard lines, the slim, powerful hands. He could read it in the tones of the voice,—tones that he himself could not imitate or pretend. The hour had come for the settling of old debts.

He tried to curse his adversary as a weakling and a degenerate, but the obscene words he sought for would not come to his lips. Here was his fate, and because the darkness always fades before the light, and the courage of wickedness always breaks before the courage of righteousness, Cranston was afraid to look it in the face. The fear of defeat, of death, of Heaven knows what remorselessness with which this grave giant would administer justice was upon him, and his heart seemed to freeze in his breast. Cravenly he leaped for his knife on the blankets below him.

Dan was upon him before he ever reached it. He sprang as a cougar springs, incredibly fast and with shattering power. Both went down, and for a long time they writhed and struggled in each other's arms. The pine boughs rustled strangely.

The dark, gaunt hand reached in vain for the knife. Some resistless power seemed to be holding his wrist and was bending its bone as an Indian bends a bow. Pain lashed through him.—And then this dark-hearted man, who had never known the meaning of mercy, opened his lips to scream that this terrible enemy be merciful to him.

But the words wouldn't come. A ghastly weight had come at his throat, and his tortured lungs sobbed for breath. Then, for a long time, there was a curious pounding, lashing sound in the evergreen boughs. It seemed merciless and endless.

But Dan got up at last, in a strange, heavy silence, and swiftly went to work. He took the rifle and filled it with cartridges from Cranston's belt. Then he put the remaining two boxes of shells into his shirt pocket. The supplies of food—the sack of nutritious jerked venison like dried bark, the little package of cheese, the boxes of hardtack and one of the small sacks of prepared flour—he tied, with a single kettle, into his heavy blankets and flung them with the rifle upon his back. Finally he took the pair of snowshoes from the floor. He worked coldly, swiftly, all the time munching at a piece of jerked venison. When he had finished he walked to the door of the lean-to.

It seemed to Dan that Cranston whispered faintly, from his unconsciousness, as he passed; but the victor did not turn to look. The snowshoes crunched away into the darkness. On the hill behind a half-dozen wolves—stragglers from the pack—frisked and leaped about in a curious way. A strange smell had reached them on the wind, and when the loud, fearful steps were out of hearing, it might pay them to creep down, one by one, and investigate its cause.
