a second time that morning a thrilling cry escaped his lips. On a projecting thorny twig, glistening full in the sun, there fluttered a long, silken strand of hair. He reached out for it, but Wabi caught his hand, and in another moment Mukoki had joined them. Gently he took the raven tress between his fingers, his deep-set eyes glaring like red coals of fire. It was a strand of Minnetaki's beautiful hair, not for a moment did one of them doubt that; but what held them most, what increased the horror in their eyes, was the quantity of it! Suddenly Mukoki gave it a gentle pull and the tress slipped free of the twig.
In the next breath he uttered the only expression of supreme disgust in his vocabulary a long-drawn, hissing sound which he used only in those moments when his command of English was entirely inadequate to the situation.
"Minnetaki on other sledge!"
He showed the end of the strand to his young companions.
"See—hair been cut! No pulled out by, twig. Woonga hang heem there—make us think wrong."
He waited for no reply, but darted back to the other trail, with Wabi and Rod close behind him. A quarter of a mile farther on the old pathfinder paused and pointed in exultant silence at a tiny footprint close beside the path of the sledge. At almost regular intervals now there appeared this sign of Minnetaki's moccasin. Her two guards were running ahead of the sledge, and it was apparent to the pursuers that Wabi's sister was taking advantage of her opportunities to leave these signs behind for those whom she knew would make an attempt at her rescue. And yet, as they left farther and farther behind them the trail which ran into the northeast, an inexplicable feeling of uneasiness began to steal over Rod. What if Mukoki had made a mistake? His confidence in the old warrior's judgment and sagacity was usually absolute, but it occurred to him, like an ugly humor to stir up his fears, that if the Woongas could cut off a bit of the girl's hair they could also take off one of her shoes! Several times he was on the point of giving audible voice to his suspicions but refrained from doing so when he saw the assurance with which both Wabi and Mukoki followed the trail.
Finally he could hold himself no longer.
"Wabi, I'm going back," he cried softly, forging alongside his companion. "I'm going back and follow the other trail. If I don't find anything in a mile or so I'll return on the double-quick and overtake you!"
Wabi's efforts to dissuade him were futile, and a few minutes later Rod was again at the clearing. What presentiment was it that caused his heart to beat faster and his breath to come in tense excitement as he stole through the bushes where they had found the silken tress of hair? What something was it, away down in his soul, that kept urging him on and on, even after he had gone a mile, and then two miles, in fruitless search? Rod could not have answered these questions had he stopped to ask them of himself. He was not superstitious. He did not believe in dreams. And yet each moment, without apparent reason added to his conviction that Mukoki had made a mistake, and that Minnetaki was on the sledge ahead of him.
The country into which he was penetrating grew wilder. Rocky ridges rose before him, split by rifts and gullies through which the water must have rushed in torrents in the spring. He listened, and proceeded more cautiously; and through his mind there flashed a memory of his thrilling exploration of the mysterious chasm of a few weeks before, when, in his lonely night camp, he had dreamed of the skeletons. He was thinking of this when he came around the end of a huge rock which lay as big as a house in his path. Upon the snow, almost at his feet, was a sight that froze the blood in his veins. For the second time that day he gazed upon the distorted features of a dead man. Squarely across the trail, as the other had lain, was the body of an Indian, his arms outstretched, his twisted face turned straight up to the clear sky, the snow about his head glistening a sickening red in the sun. For a full minute Rod gazed in silent horror on the scene. There was no sign of a struggle, there were no footprints in the snow. The man had been killed while upon the sledge, and the only mark he had made was when he had fallen off.
Who had killed him?
Had Minnetaki saved herself by taking her captor's life?
For a moment Rod was almost convinced that this was so. He examined the stains in the snow and found that they were still damp and unfrozen. He was sure that the tragedy had occurred less than an hour before. More cautiously, and yet swifter than before, he followed the trail of the sledge, his rifle held in readiness for a shot at any moment. The path became wilder and in places it seemed almost inaccessible. But between the tumbled mass of rock the sledge had found its way, its savage driver not once erring in his choice of the openings ahead. Gradually the trail ascended until it came to the summit of a huge ridge. Hardly had Rod reached the top when another trail cut across that of the sledge.
Deeply impressed in the softening snow were the footprints of a big bear!
The first warm sunshine, thought Rod, had aroused the beast from his winter sleep, and he was making a short excursion from his den. From where the bear had crossed the trail the sledge turned abruptly in the direction from which the bear had come.
Without giving a thought to his action, Rod began his descent of the ridge in the trail made by the bear, at the same time keeping his eyes fixed upon the sledge track and the distant forest. At the foot of the ridge the great trunk of a fallen tree lay in his path, and as he went to climb over it he stopped, a cry of amazement stifling itself in his throat. Over that tree the bear had scrambled, and upon it, close to the spot where the animal had brushed off the snow in his passage, was the imprint of a human hand!
For a full minute Rod stood as motionless as if he had been paralyzed, scarcely breathing in his excitement. The four fingers and thumb of the hand had left their impressions with startling clearness. The fingers were long and delicately slender, the palm narrow. The imprint had assuredly not been made by the hand of a man!
Recovering himself, Rod looked about him. There were no marks in the snow except those of the bear. Was it possible that he was mistaken? He scrutinized the mysterious handprint again. As he gazed an uncanny chill crept through him, and when he raised his head he knew that he was trembling in spite of his efforts to control himself. Turning about he swiftly followed the trail to the top of the ridge, recrossed the sledge track, and descended again into the wildness of the gorge on the other side. He had not progressed twenty rods when without a sound he dropped behind a rock. He had seen no movement ahead of him. He had heard nothing. Yet in that moment he was thrilled as never before in his life.
For the bear trail had ceased.
And ahead of him, instead of the tracks of a beast, there continued the footprints of a man!
CHAPTER V
ROD'S FIGHT FOR LIFE
It was some time before Roderick moved from his concealment behind the rock. It was not fear that held him there, but a knowledge within him that he needed to think, to collect his senses as he would have expressed it if Wabi had been with him. For a brief spell he was stunned by the succession of surprises which he had encountered, and he felt that now, if ever in his life, he needed control of himself. He did not attempt to solve the mystery of the trail beyond the fact that it was not made by a bear and that the handprint on the log was not made by a man. But he was certain of one thing. In some way Minnetaki was associated with both.
When he continued his pursuit he made his way with extreme caution. At each new turn in the trail he fell behind some rock or clump of bushes and scanned the gorge as far as he could see ahead of him. But each moment these distances of observation became shorter. The ridge on his left became almost a sheer wall; on his right a second ridge closed in until the gorge
