fire and the explosion of a gun, and as Mukoki crumpled down in his tracks there followed a cry so terrible, so unhuman, so blood-curdling that, as he fell, an answering cry of horror burst from the lips of the old warrior. He lay like dead, though he was not touched. Instinct more than reason had impelled him to fall at the sound of the mysterious shot. Cautiously he wormed his rifle to his shoulder. But there came no movement from the rocks.
Then, from half-way down the mountain, there came again that terrible cry, and Mukoki knew that no animal in all these wilds could make it, but that it was human, and yet more savage than anything that had ever brought terror into his soul. Trembling, he crouched to the earth, a nameless fear chilling the blood in his veins. And the cry came again, and yet again, always farther and farther away, now at the foot of the mountain, now upon the plain, now floating away toward the chasm, echoing and reechoing between the mountain ridges, startling the creatures of the night into silence, and wresting deep sobbing breaths from out of Mukoki's soul. And the old warrior moved not a muscle until far away, miles and miles, it seemed, there died the last echo of it, and only the whispering winds rustled over the mountain top.
CHAPTER XI
THE CRY IN THE CHASM
If Mukoki had been a white man he would have analyzed in some way the meaning of those strange cries. But the wild and its savage things formed his world; and his world, until this night, had never known human or beast that could make the terrible sounds he had heard. So for an hour he crouched where he had fallen, still trembling with that nameless fear, and trying hard to form a solution of what had happened. Slowly he recovered himself. For many years he had mingled with white people at the Post and reason now battled with the superstitions of his race.
He had been fired at. He had heard the whistling song of the ball over his head, and had heard it strike the tree behind him. For a time those rocks toward which he stared like fascinated beast had concealed a man. But what kind of man! He remembered the ancient battle-cries of his tribe, and of the enemies of his tribe, but none was like the cries that had followed the shot. He heard them still; they rang in his ears, and sent shivering chills up his back. And the more he tried to reason the greater that nameless fear grew in him, until he slunk like an animal down the side of the mountain, through the dip, and out again upon the plain. And with that same nameless fear always close behind him, urging him on with its terrors, he sped back over the trail that he had followed that day, nor for an instant did he stop to rest until he came to the camp-fire of Rod and Wabigoon.
Usually an Indian hides his fears; he conceals them as a white man does his sins. But to-night Mukoki's experience had passed beyond the knowledge of his race, and he told of what had happened, trembling still, cringing when a great white rabbit darted close to the fire. Rod and Wabi listened to him in mute astonishment.
"Could it have been a Woonga?" asked Wabi.
"No Woonga," replied the old warrior quickly, shaking his head. "Woonga no mak' noise lak that!"
He drew away from the fire, wrapped himself in a blanket, and crept into the shelter that Rod and Wabigoon had built. The two boys looked at each other in silence.
"Muky has certainly had some most extraordinary adventure," said Wabi at last. "I have never seen him like this before. It is easy to guess the meaning of the shot. Some of the Woongas may still be in the country, and one of them saw Mukoki, and fired at him. But the scream! What do you make of that?"
"Do you suppose," whispered Rod, speaking close to his companion's ear, "that Mukoki's imagination helped him out to-night?" He paused for a moment as he saw the look of disapproval in Wabigoon's eyes, and then went on. "I don't mean to hint that he stretched his story purposely. He was standing on the mountain top. Suddenly there came a flash of fire, the report of a rifle, and a bullet zipped close to his head. And at that same instant, or a moment later—well, you remember the scream of the lynx!"
"You believe that it might have been a lynx, startled by the shot, and sent screaming across the plain?"
"Yes."
"Impossible. At the sound of that shot a lynx would have remained as still as death!"
"Still there are always exceptions," persisted the white youth.
"Not in the case of lynx," declared Wabigoon. "No animal made those cries. Mukoki is as fearless as a lion. The cry of a lynx would have stirred his blood with pleasure instead of fear. Whatever the sounds were they turned Mukoki's blood into water. They made him a coward, and he ran, ran, mind you! until he got back to us! Is that like Mukoki? I tell you the cries—"
"What?"
"Were something very unusual," finished Wabigoon quietly, rising to his feet "Perhaps we will find out more to-morrow. As it is, I believe we had better stand guard in camp to-night. I will go to bed now and you can awaken me after a while."
Wabigoon's words and the strangeness of his manner put Rod ill at ease, despite his arguments of a few moments before, and no sooner did he find himself alone beside the fire than he began to be filled with an unpleasant premonition of lurking danger. For a time he sat very still, trying to peer into the shadows beyond the fire and listening to the sounds that came to him from out of the night. As he watched and listened his brain worked ceaselessly, conjuring picture after picture of what that danger might be, and at last he drew out of the firelight and concealed himself in the deep gloom of the bush. From here he could see the camp, and at the same time was safe from a possible rifle shot.
The night passed with tedious slowness, and he was glad when, a little after midnight, Wabi came out to relieve him. At dawn he was in turn awakened by the young Indian. Mukoki was already up and had prepared his pack. Apparently he had regained his old spirits, but both Rod and Wabigoon could see that behind them the fear of the preceding night still haunted him. That morning he did not set off ahead of the two boys with his pack but walked beside them, stopping to rest when they lowered their canoe, his eyes never ceasing their sharp scrutiny of the plain and distant ridges. Once when Mukoki mounted a big rock to look about him, Wabi whispered, "I tell you it's strange, Rod—mighty strange!"
An hour later the old warrior halted and threw off his load. The three had approached within a quarter of a mile of the dip in the mountain.
"Leave canoe here," he said. "Go lak fox to old camp. Mebbe see!"
He took the lead now, followed closely by the boys. The safety of the old pathfinder's rifle was down, and following his example Rod and Wabigoon held their own guns in readiness for instant fire. As they neared the summit of the ridge on which Mukoki's life had been attempted the suspense of the two young hunters became almost painfully acute. Mukoki's actions not only astonished them, but set their blood tingling with his own strange fear. Many times had Wabigoon seen his faithful comrade in moments of deadly peril but never, even when the Woongas were close upon their trail, had he known him to take them as seriously as he did the ascent of this mountain. Every few steps Mukoki paused, listening and watchful. Not the smallest twig broke under his moccasined feet; the movement of the smallest bird, the trembling of a bush, the scurry of a rabbit halted him, rigid, his rifle half to shoulder. And Rod and Wabigoon soon become filled with this same panic-stricken fear. What terrible dread was it that filled Mukoki's soul? Had he seen something of which he had not told them? Did he think something which he had not revealed?
Foot by foot the three came to the top of the ridge. There Mukoki straightened himself, and stood erect. There were no signs of a living creature about them. Down in the dip nestled the little lake, gleaming in the midday sun. They could make out
