of such a possibility filled him with glee.
"Well, that fellow may be an ordinary red fox," explained the Indian youth. "If so, he is only worth from ten to twenty dollars; or he may be a black fox, worth fifty or sixty; or what we call a 'cross'—a mixture of silver and black—worth from seventy-five to a hundred. Or—"
"Heap big silver!" interrupted Mukoki with another chuckle.
"Yes, or a silver," finished Wabi. "A poor silver is worth two hundred dollars, and a good one from five hundred to a thousand! Now do you see why we would like to have a difference in the tracks? If that was a silver, a black or a 'cross,' we'd follow him; but in all probability he is red."
Every hour added to Rod's knowledge of the wilderness and its people. For the first time in his life he saw the big dog-like tracks made by wolves, the dainty hoof-prints of the red deer and the spreading imprints of a traveling lynx; he pictured the hugeness of the moose that made a track as big as his head, discovered how to tell the difference between the hoof-print of a small moose and a big caribou, and in almost every mile learned something new.
Half a dozen times during the morning the hunters stopped to rest. By noon Wabi figured that they had traveled twenty miles, and, although very tired, Rod declared that he was still "game for another ten." After dinner the aspect of the country changed. The river which they had been following became narrower and was so swift in places that it rushed tumultuously between its frozen edges. Forest-clad hills, huge boulders and masses of rock now began to mingle again with the bottoms, which in this country are known as plains. Every mile added to the roughness and picturesque grandeur of the country. A few miles to the east rose another range of wild and rugged hills; small lakes became more and more numerous, and everywhere the hunters crossed and recrossed frozen creeks.
And each step they took now added to the enthusiasm of Wabi and his companions. Evidences of game and fur animals were plenty. A thousand ideal locations for a winter camp were about them, and their progress became slow and studied.
A gently sloping hill of considerable height now lay in their path and Mukoki led the ascent. At the top the three paused in joyful astonishment. At their feet lay a "dip," or hollow, a dozen acres in extent, and in the center of this dip was a tiny lake partly surrounded by a mixed forest of cedar, balsam and birch that swept back over the hill, and partly inclosed by a meadow-like opening. One might have traveled through the country a thousand times without discovering this bit of wilderness paradise hidden in a hilltop. Without speaking Mukoki threw off his heavy pack. Wabi unbuckled his harness and relieved his shoulders of their burden. Rod, following their example, dropped his small pack beside that of the old Indian, and Wolf, straining at his babeesh thong, gazed with eager eyes into the hollow as though he, too, knew that it was to be their winter home.
Wabi broke the silence.
"How is that, Muky?" he asked.
Mukoki chuckled with unbounded satisfaction.
"Ver' fine. No get bad wind—never see smoke—plenty wood—plenty water."
Relieved of their burdens, and leaving Wolf tied to the toboggan, the hunters made their way down to the lake. Hardly had they reached its edge when Wabi halted with a startled exclamation and pointed into the forest on the opposite side.
"Look at that!"
A hundred yards away, almost concealed among the trees, was a cabin. Even from where they stood they could see that it was deserted. Snow was drifted high about it. No chimney surmounted its roof. Nowhere was there a sign of life.
Slowly the hunters approached. It was evident that the cabin was very old. The logs of which it was built were beginning to decay. A mass of saplings had taken root upon its roof, and everything about it gave evidence that it had been erected many years before. The door, made of split timber and opening toward the lake, was closed; the one window, also opening upon the lake, was tightly barred with lengths of sapling.
Mukoki tried the door, but it resisted his efforts. Evidently it was strongly barred from within.
Curiosity now gave place to astonishment.
How could the door be locked within, and the window barred from within, without there being somebody inside?
For a few moments the three stood speechless, listening.
"Looks queer, doesn't it?" spoke Wabi softly.
Mukoki had dropped on his knees beside the door. He could hear no sound. Then he kicked off his snow-shoes, gripped his belt-ax and stepped to the window.
A dozen blows and one of the bars fell. The old Indian sniffed suspiciously, his ear close to the opening. Damp, stifling air greeted his nostrils, but still there was no sound. One after another he knocked off the remaining bars and thrust his head and shoulders inside. Gradually his eyes became accustomed to the darkness and he pulled himself in.
Half-way—and he stopped.
"Go on, Muky," urged Wabi, who was pressing close behind.
There came no answer from the old Indian. For a full minute he remained poised there, as motionless as a stone, as silent as death.
Then, very slowly—inch by inch, as though afraid of awakening a sleeping person, he lowered himself to the ground. When he turned toward the young hunters it was with an expression that Rod had never seen upon Mukoki's face before.
"What is it, Mukoki?"
The old Indian gasped, as if for fresh air.
"Cabin—she filled with twent' t'ousand dead men!" he replied.
CHAPTER VII
RODERICK DISCOVERS THE BUCKSKIN BAG
For one long breath Rod and Wabi stared at their companion, only half believing, yet startled by the strange look in the old warrior's face.
"Twent' t'ousand dead men!" he repeated. As he raised his hand, partly to give emphasis and partly to brush the cobwebs from his face, the boys saw it trembling in a way that even Wabi had never witnessed before.
"Ugh!"
In another instant Wabi was at the window, head and shoulders in, as Mukoki had been before him. After a little he pulled himself back and as he glanced at Rod he laughed in an odd thrilling way, as though he had been startled, but not so much so as Mukoki, who had prepared him for the sight which had struck his own vision with the unexpectedness of a shot in the back.
"Take a look, Rod!"
With his breath coming in little uneasy jerks Rod approached the black aperture. A queer sensation seized upon him—a palpitation, not of fear, but of something; a very unpleasant feeling that seemed to choke his breath, and made him wish that he had not been asked to peer into that mysterious darkness. Slowly he thrust his head through the hole. It was as black as night inside. But gradually the darkness seemed to be dispelled. He saw, in a little while, the opposite wall of the cabin. A table outlined itself in deep shadows, and near the table there was a pile of something that he could not name; and tumbled over that was a chair, with an object that might have been an old rag half covering it.
His eyes traveled nearer. Outside Wabi and Mukoki heard a startled, partly suppressed cry. The boy's hands gripped the sides of the window. Fascinated, he stared down upon an object almost within arm's reach of him.
There, leaning against the cabin wall, was what half a century or more ago had been a living man! Now it was a mere skeleton, a grotesque, terrible-looking object, its empty eye-sockets gleaming dully with the light from the window, its grinning mouth, distorted into ghostly life by the pallid mixture of light and gloom, turned full up at him!
Rod fell back, trembling and white.
"I only saw one," he gasped, remembering
