The lad, who was looking on, could only conjecture the meaning of what passed before his eyes. When he saw a couple of warriors rise to their feet and come toward him, he supposed it was to make hunt for him and his friends. He was made to realize, too, the delicately dangerous position in which he stood. When the figures plainly outlined against the illumination of the camp-fire started, he fervently wished himself elsewhere. He dared not stir, for, as if fate were dallying with him, a lot of wood, thrown on the blaze within a few minutes before, threw a circle of light to the base of the tree from behind which he was cautiously peering. Had he started to withdraw, the two Shawanoes would have been upon him in a twinkling. He could only wait where he was, and hope they might pass by without detecting his presence. He hardly breathed as he heard the rustling of their moccasins on the leaves, and pressed his upright figure against the bark as though he would force himself into the very structure of the tree itself. Fortunately the suspense quickly passed. If the couple were hunting for him and his companion, they did not expect to find either so near headquarters, and speedily vanished in the gloom beyond, stepping so softly that their footfalls became inaudible. This incident gave young Edwards a good scare. He felt that he had run an unnecessary risk, and wasted time in staying so long after learning that Larry was not with the main party of Indians. More of these were likely to leave the camp, and the danger of his position must increase. Without delay, therefore, he began his retrograde movement. This was easy, and he soon placed himself where he could feel comparatively safe. His curiosity led him to pick his way back to the torrent that had been the scene of so many moving incidents of the afternoon. He was somewhat confused as to the points of the compass, but the faint roar was his guide, and with little trouble he placed himself quite near the stream, which coursed between the rocks with such impetuosity. The youth was too prudent to advance into the moonlight, where the prowlers were liable to see him, and so it happened that he approached the rocks at a point that was new to him. To this fact was due a surprise. He was just in time to see one Indian following the other across the foot-bridge made by the prostrate tree. "I never suspected that was there," he said to himself when he comprehended its meaning; "I thought there was no means by which Larry could make his way back to the trail without swimming below the falls or fording some place farther up. I wonder whether he knows about that?"
