Henry was sure now that what he had heard was the product of a too vivid fancy, but a little later he was not so sure. It must be the faint cry of a wolf that he now heard or its echo. He had the keenest ear of them all, and that Tom Ross did not hear the sound, was no proof. A vivid imagination often means a prompt and powerful man of action, and Henry acted at once. "Tom," he whispered, "I'm going to scout in the distance from which I thought the sounds came. Don't wake the boys; I'll be back before morning." Tom Ross nodded. He did not believe that Henry had really heard anything, and he would have remonstrated with him, but he knew that it was useless. He merely drew his blanket a little closer, and resolved that one pair of eyes should watch as well as two had watched before. Henry folded his blankets, put them in his little pack, and in a minute was gone. It was dark, but not so dark that one used to the night could not see. The sounds that he had seemed to hear came from the southwest, and the road in the direction was easy, grown up with forest but comparatively free from undergrowth. He walked swiftly about a mile, then he heard the cry of the wolf again. Now, the last doubt was gone from his mind. It was a real sound, and it was made by Indian calling to Indian. He corrected his course a little, and went swiftly on. He heard the cry once more, now much nearer, and, in another mile, he saw a glow among the trees. He went nearer and saw detached cones of light. Then he knew that it was a camp fire, and a camp fire built there boldly in that region, so dangerous to the Kentuckian, indicated that it was surely the Indians themselves and their allies. He did not believe that it was the force of Timmendiquas which could only have reached this spot by turning from its course, but he intended to solve the doubt. The camp was in one of the little prairies so numerous in the old Northwest, and evidently had been pitched there in order to secure room for the fires. Henry concluded at once that it must be a large force, and his eagerness to know increased. As he crept nearer and nearer, he was amazed by the number of the fires. This was a much larger band than the one led by Timmendiquas. He also heard the sound of many voices and of footsteps. From his place among the trees he saw dark figures passing and repassing. He also caught now and then a metallic glitter from something not a rifle or a tomahawk, but which he could not clearly make out in the dark.
