Had he discovered a trail, or something worse? He was only thirty feet away from the mangled corpse of the first scout. He was only ten feet away from the spot where the death-blow had been given. It was the trail of his lost comrade that he had discovered, but what next?

It was a moment fraught with intense excitement for the watchers. The issues to these three adventurers were life or death. Once he discovered the truth that was hidden in those bushes, a single call for assistance would fill the forest with blood-thirsty hornets, and all would be lost.

What could be done? He was too far away to be dispatched like his comrade, and a rifle-shot would alarm the camp. Step by step he advanced. Then his eager eyes caught sight of the fresh blood-marks and evidences of the recent scuffle.

The Indian gazed at the red spots, and followed their trail to the bushes. Then, as his eyes caught sight of the mangled corpse, he uttered a blood-curdling yell that made the dark aisles of the forest resound. At the same instant Jamie's rifle spoke out, and the Indian fell to the ground.

Five seconds had scarcely passed when from the camp there came the answering yell. It was a wild, fierce cry of revenge that brought the whole pack upon their trail.

"Lead on, quickly!"
