haunches again and sent back the call that comes only when there is blood upon the trail or when near the killing time.
There was not the rustle of a bough, not a word spoken, by the silent watchers in the spruce. Mukoki had slipped back and half lay across his support in shooting attitude. Wabi had braced a foot, and his rifle was half to his shoulder, leveled over a knee. It was Rod's turn with the big revolver, and he had practised aiming through a crotch that gave a rest to his arm.
In a few moments there came again the howl of the distant wolf on the plains, and this time it was joined by another away to the westward. And after that there came two from the plains instead of one, and then a far cry to the north and east. For the first time Rod and Wabi heard the gloating chuckle of Mukoki in his spruce a dozen feet away.
At the increasing responses of his brethren Wolf became more frantic in his efforts. The scent of fresh blood and of wounded game was becoming maddening to the captive. But his frenzy no longer betrayed itself in futile efforts to escape from the babeesh thong. Wolf knew that his cries were assembling the hunt-pack. Nearer and nearer came the responses of the leaders, and there were now only momentary rests between the deep-throated exhortations which he sent in all directions into the night.
Suddenly, almost from the swamp itself, there came a quick, excited, yelping reply, and Wabi gripped Rod by the arm.
"He has struck the place where you killed the buck," he whispered. "There'll be quick work now!"
Hardly had he spoken when a series of excited howls broke forth from the swamp, coming nearer and nearer as the hunger-crazed outlaw of the plains followed over the rich-scented trail made by the two Indians as they carried the slaughtered deer. Soon he nosed one of the trails of blood, and a moment later the watchers saw a gaunt shadow form running swiftly over the snow toward Wolf.
For an instant, as the two beasts of prey met, there fell a silence; then both animals joined in the wailing hunt-pack cry, and the wolf that was free came to the edge of the great rock and stood with his fore feet on its side, and his cry changed from that of the chase to the still more thrilling signal that told the gathering pack of game at bay.
Swiftly the wolves closed in. From over the edge of the mountain one came and joined the wolf at the rock without the hunters seeing his approach. From out of the swamp there came a pack of three, and now about the rock there grew a maddened, yelping horde, clambering and scrambling and fighting in their efforts to climb up to the game that was so near and yet beyond their reach. And sixty feet away Wolf crouched, watching the gathering of his clan, helpless, panting from his choking efforts to free himself, and quieting, gradually quieting, until in sullen silence he looked upon the scene, as though he knew the moment was very near when that thrilling spectacle would be changed into a scene of direst tragedy.
And it was Mukoki who had first said that this was the vengeance of Wolf upon his people.
From Mukoki there now came a faint hissing warning, and Wabi threw his rifle to his shoulder. There were at least a score of wolves at the base of the rock. Gradually the old Indian pulled upon the babeesh rope that led to the dead buck—pulled until he was putting a half of his strength into the effort, and could feel the animal slowly slipping from the flat ledge. A moment more and the buck tumbled down in the midst of the waiting pack.
As flies gather upon a lump of sugar the famished animals now crowded and crushed and fought over the deer's body, and as they came thus together there sounded the quick sharp signal to fire from Mukoki.
For five seconds the edge of the spruce was a blaze of death-dealing flashes, and the deafening reports of the two rifles and the big Colt drowned the cries and struggles of the animals. When those five seconds were over fifteen shots had been fired, and five seconds later the vast, beautiful silence of the wilderness night had fallen again. About the rock was the silence of death, broken only faintly by the last gasping throes of the animals that lay dying in the snow.
In the trees there sounded the metallic clink of loading shells.
Wabi spoke first.
"I believe we did a good job, Mukoki!"
Mukoki's reply was to slip down his tree. The others followed, and hastened across to the rock. Five bodies lay motionless in the snow. A sixth was dragging himself around the side of the rock, and Mukoki attacked it with his belt-ax. Still a seventh had run for a dozen rods, leaving a crimson trail behind, and when Wabi and Rod came up to it the animal was convulsed in its last dying struggles.
"Seven!" exclaimed the Indian youth. "That is one of the best shoots we ever had. A hundred and five dollars in a night isn't bad, is it?"
The two came back to the rock, dragging the wolf with them. Mukoki was standing as rigid as a statue in the moonlight, his face turned into the north. He pointed one arm far out over the plains, and said, without turning his head,
"See!"
Far out in that silent desolation the hunters saw a lurid flash of flame. It climbed up and up, until it filled the night above it with a dull glow—a single unbroken stream of fire that rose far above the swamps and forests of the plains.
"That's a burning jackpine!" said Wabigoon.
"Burning jackpine!" agreed the old warrior. Then he added, "Woonga signal fire!"
CHAPTER X
RODERICK EXPLORES THE CHASM
To Rod the blazing pine seemed to be but a short distance away—a mile, perhaps a little more. In the silence of the two Indians as they contemplated the strange fire he read an ominous meaning. In Mukoki's eyes was a dull sullen glare, not unlike that which fills the orbs of a wild beast in a moment of deadly anger. Wabi's face was filled with an eager flush, and three times, Rod observed, he turned eyes strangely burning with some unnatural passion upon Mukoki.
Slowly, even as the instincts of his race had aroused the latent, brutish love of slaughter and the chase in the tamed wolf, the long smothered instincts of these human children of the forest began to betray themselves in their bronzed countenances. Rod watched, and he was thrilled to the soul. Back at the old cabin they had declared war upon the Woongas. Both Mukoki and Wabigoon had slipped the leashes that had long restrained them from meting first vengeance upon their enemies. Now the opportunity had come. For five minutes the great pine blazed, and then died away until it was only a smoldering tower of light. Still Mukoki gazed, speechless and grim, out into the distance of the night. At last Wabi broke the silence.
"How far away is it, Muky?"
"T'ree mile," answered the old warrior without hesitation.
"We could make it in forty minutes."
"Yes."
Wabi turned to Rod.
"You can find your way back to camp alone, can't you?" he asked.
"Not if you're going over there!" declared the white boy. "I'm going with you."
Mukoki broke in upon them with a harsh disappointed laugh.
"No go. No go over there." He spoke with emphasis, and shook his head. "We lose pine in five minutes. No find Woonga camp—make big trail for Woongas to see in morning. Better wait. Follow um trail in day, then shoot!"
