Rod darted along the ridge to meet him, firing a single shot now and then to let him know where he was, and in fifteen minutes Mukoki came panting up the mountain.

"The Woongas!" shouted Rod. "They've attacked the camp! See!" He pointed to the cloud of smoke. "I heard shots—I heard shots—"

For an instant the grim pathfinder gazed in the direction of the burning camp, and then without a word he started at terrific speed down the mountain.

The half-hour race that followed was one of the most exciting experiences of Rod's life. How he kept up with Mukoki was more than he ever could explain afterward. But from the time they struck the old trail he was close at the Indian's heels. When they reached the hill that sheltered the dip his face was scratched and bleeding from contact with swinging bushes; his heart seemed ready to burst from its tremendous exertion; his breath came in an audible hissing, rattling sound, and he could not speak. But up the hill he plunged behind Mukoki, his rifle cocked and ready. At the top they paused.

The camp was a smoldering mass of ruins. Not a sign of life was about it. But—

With a gasping, wordless cry Rod caught Mukoki's arm and pointed to an object lying in the snow a dozen yards from where the cabin had been. The warrior had seen it. He turned one look upon the white youth, and it was a look that Rod had never thought could come into the face of a human being. If that was Wabi down there—if Wabi had been killed—what would Mukoki's vengeance be! His companion was no longer Mukoki—as he had known him; he was the savage. There was no mercy, no human instinct, no suggestion of the human soul in that one terrible look. If it was Wabi—

They plunged down the hill, into the dip, across the lake, and Mukoki was on his knees beside the figure in the snow. He turned it over—and rose without a sound, his battle-glaring eyes peering into the smoking ruins.

Rod looked, and shuddered.

The figure in the snow was not Wabi.

It was a strange, terrible-looking object—a giant Indian, distorted in death—and a half of his head was shot away!
