shelters. Here the tracks in the snow were much fresher; in places they seemed to have been but lately made. Still there were no evidences of the captured girl. The boys could see that Mukoki himself had found no explanation for the sudden freshness of the trail and for the absence of Minnetaki's footprints among the tracks. Again and again the shrewd old pathfinder went over the camp. Not a sign escaped his eyes, not a mark or a broken stick but that was examined by him. Rod knew that Minnetaki's capture must have occurred at least three days before, and yet the tracks about this camp were not more than a day old, if they were that. What did it mean?
The very mystery of the thing filled him with a nameless fear. Why had not the outlaw Woongas continued their flight? Why this delay so near the scene of their crime? He glanced at Wabi, but the Indian youth was as bewildered as himself. In his eyes, too, there was the gleam of a fear which he could not have named.
Mukoki was beside the charred remains of the fire. He had buried his hand deep among them, and when he rose be made a sign toward Rod's watch.
"Eight o'clock, Mukoki."
"Woonga here las' night," declared the old Indian slowly. "Leave camp four hour ago!"
What did it mean?
Had Minnetaki been hurt, so dangerously hurt that her captors had not dared to move her?
Rod asked himself no more questions. But he was trembling. And Mukoki and Wabigoon went on with strange, unnatural faces and breathed not the whisper of a word between them. The mystery was beyond them all. But one thing they realized, whatever had happened they were close upon the heels of the savages. And each step brought them nearer, for with every mile the freshness of the trail increased. Then came another great surprise.
The trail divided!
At the edge of a small opening the Indians had separated themselves into two parties. The trail of one sledge led into the northeast, that of the other into the northwest!
With which sledge was Minnetaki? They looked at one another in bewilderment.
Mukoki pointed to the trail into the northeast.
"We must fin' sign—sign of Minnetaki. You take that—I take this!"
Rod started off at a dog trot over the easternmost trail. At the farther side of the opening, where the sledge had plunged into a clump of hazel, he suddenly stopped, and for 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
