their scalps, hurried on over the trail.
Half-way across the lake, where he had taken his last two shots, were the skeletons of two more wolves, and in the edge of the spruce forest he found another. This animal had evidently been wounded farther back and had later been set upon by some of the pack and killed. Half a mile deeper in the forest he came upon a spot where he had emptied five shells into the pack and here he found the bones of two more wolves. He had seven scalps in his possession when he turned back over the home trail.
Beside the remains of the old bull Wabi paused again. He knew that the Indians frequently preserved moose and caribou heads through the winter by keeping them frozen, and the head at his feet was a prize worth some thought. But how could he keep it preserved until their return, months later? He could not suspend it from the limb of a tree, as was the custom when in camp, for it would either be stolen by some passing hunter or spoiled by the first warm days of spring. Suddenly an idea came to him. Why could it not be preserved in what white hunters called an "Indian ice-box"? In an instant he was acting upon this inspiration. It was not a small task to drag the huge head to the shelter of the tamaracks, where, safely hidden from view, he made a closer examination. The head was gnawed considerably by the wolves, but Wabi had seen worse ones skillfully repaired by the Indians at the Post.
Under a dense growth of spruce, where the rays of the sun seldom penetrated, the Indian boy set to work with his belt-ax. For an hour and a half he worked steadily, and at the end of that time had dug a hole in the frozen earth three feet deep and four feet square. This hole he now lined with about two inches of snow, packed as tight as he could jam it with the butt of his gun. Then placing in the head he packed snow closely about it and afterward filled in the earth, stamping upon the hard chunks with his feet. When all was done he concealed the signs of his work under a covering of snow, blazed two trees with his ax, and resumed his journey.
"There is thirty dollars for each of us if there's a cent," he mused softly, as he hurried toward the Ombabika. "That ground won't thaw out until June. A moose-head and eight scalps at fifteen dollars each isn't bad for one day's work, Rod, old boy!"
He had been absent for three hours. It had been snowing steadily and by the time he reached their old camp the trail left by Rod and Mukoki was already partly obliterated, showing that they had secured an early start up the river.
Bowing his head in the white clouds falling silently about him, Wabi started in swift pursuit. He could not see ten rods ahead of him, so dense was the storm, and at times one side or the other of the river was lost to view. Conditions could not have been better for their flight out of the Woonga country, thought the young hunter. By nightfall they would be many miles up the river, and no sign would be left behind to reveal their former presence or to show in which direction they had gone. For two hours he followed tirelessly over the trail, which became more and more distinct as he proceeded, showing that he was rapidly gaining on his comrades. But even now, though the trail was fresher and deeper, so disguised had it become by falling snow that a passing hunter might have thought a moose or caribou had passed that way.
At the end of the third hour, by which time he figured that he had made at least ten miles, Wabi sat down to rest, and to refresh himself with the lunch which he had taken from the camp that morning. He was surprised at Rod's endurance. That Mukoki and the white boy were still three or four miles ahead of him he did not doubt, unless they, too, had stopped for dinner. This, on further thought, he believed was highly probable.
The wilderness about him was intensely still. Not even the twitter of a snow-bird marred its silence. For a long time Wabi sat as immovable as the log upon which he had seated himself, resting and listening. Such a day as this held a peculiar and unusual fascination for him. It was as if the whole world was shut out, and that even the wild things of the forest dared not go abroad in this supreme moment of Nature's handiwork, when with lavish hand she spread the white mantle that was to stretch from the border to Hudson Bay.
As he listened there came to him suddenly a sound that forced from between his lips a half-articulate cry. It was the clear, ringing report of a rifle! And following it there came another, and another, until in quick succession he had counted five!
What did it mean? He sprang to his feet, his heart thumping, every nerve in him prepared for action. He would have sworn it was Mukoki's rifle—yet Mukoki would not have fired at game! They had agreed upon that.
Had Rod and the old Indian been attacked? In another instant Wabi was bounding over the trail with the speed of a deer.
CHAPTER V
MYSTERIOUS SHOTS IN THE WILDERNESS
As the Indian youth sped over the trail in the direction of the rifle-shots he flung his usual caution to the winds. His blood thrilled with the knowledge that there was not a moment to lose—that even now, in all probability, he would be too late to assist his friends. This fear was emphasized by the absolute silence which followed the five shots. Eagerly, almost prayerfully, he listened as he ran for other sounds of battle—for the report of Mukoki's revolver, or the whoops of the victors. If there had been an ambush it was all over now. Each moment added to his conviction, and as he thrust the muzzle of his gun ahead of him, his finger hovering near the trigger and his snow-blinded eyes staring ahead into the storm, something like a sob escaped his lips.
Ahead of him the stream narrowed until it almost buried itself under a mass of towering cedars. The closeness of the forest walls now added to the general gloom, intensified by the first gray pallor of the Northern dusk, which begins to fall in these regions early in the afternoon of November days. For a moment, just before plunging into the gloomy trail between the cedars, Wabi stopped and listened. He heard nothing but the beating of his own heart, which worked like a trip-hammer within his breast. The stillness was oppressive. And the longer he listened the more some invisible power seemed to hold him back. It was not fear, it was not lack of courage, but—
What was there just beyond those cedars, lurking cautiously in the snow gloom?
With instinct that was almost animal in its unreasonableness Wabi sank upon his knees. He had seen nothing, he had heard nothing; but he crouched close, until he was no larger than a waiting wolf, and there was a deadly earnestness in the manner in which he turned his rifle into the deeper gloom of those close-knit walls of forest. Something was approaching, cautiously, stealthily, and with extreme slowness. The Indian boy felt that this was so, and yet if his life had depended upon it he could not have told why. He huddled himself lower in the snow. His eyes gleamed with excitement. Minute after minute passed, and still there came no sound. Then, from far up that dusky avenue of cedars, there came the sudden startled chatter of a moose-bird. It was a warning which years of experience had taught Wabi always to respect. Perhaps a roving fox had frightened it, perhaps the bird had taken to noisy flight at the near tread of a moose, a caribou, or a deer. But—
To Wabi the soft, quick notes of the moose-bird spelled man! In an instant he was upon his feet, darting quickly into the sheltering cedars of the shore. Through these he now made his way with extreme caution, keeping close to the bank of the frozen stream. After a little he paused again and concealed himself behind the end of a fallen log. Ahead of him he could look into the snow gloom between the cedars, and whatever was coming through that gloom would have to pass within a dozen yards of him. Each moment added to his excitement. He heard the chatter of a red squirrel, much nearer than the moose-bird. Once he fancied that he heard the striking of two objects, as though a rifle barrel had accidentally come into contact with the dead limb of a tree.
Suddenly the Indian youth imagined that he saw something—an indistinct shadow that came in the snow gloom, then disappeared, and came again. He brushed the water and snow from
