But after discovering the grizzly on my trail I went slowly along as though I was unaware of his near presence, turning in screened places to look back. He followed within three hundred feet of me. When I stopped he stopped. He occasionally watched me from behind bushes, a tree, or a bowlder. It gave me a strange feeling to have this big beast following and watching me so closely and cautiously. But I was not alarmed. I concluded to turn tables on him. On crossing a ridge where I was out of sight, I turned to the right and ran for nearly a mile. Then, circling back into our old trail behind the bear, I traveled serenely along, imagining that he was far ahead. I was suddenly startled to see a movement of the grizzly's shadow from behind a bowlder near the trail, only three hundred feet ahead. He was in ambush, waiting for me! At the place where I left the trail to circle behind him, he had stopped and evidently surmised my movements. Turning in his tracks, he had come a short distance back on the trail and lain down behind the bowlder to wait for me. I went on a few steps after discovering the grizzly, and he moved to keep out of sight. I edged toward a tall spruce, which I planned to climb if he charged, feeling safe in the knowledge that grizzlies cannot climb trees. Pausing by the spruce, I could see his silver-gray fur as he peered at me from behind the bowlder, and as I moved farther away I heard him snapping his jaws and snarling as though in anger at being outwitted. Just what he would have done had I walked into his ambush can only be guessed. Hunters trailing a wounded grizzly have been ambushed and killed. But this grizzly had not even been shot at nor harassed. Generally, when a grizzly discovers that he is followed, or even if he only thinks himself followed, he at once hurries off to some other part of his territory, as this one did after I rolled the stone. But Old Timberline on finding himself followed slipped round to follow me. Often a grizzly, if he feels he is not yet seen,--that his move is unsuspected,--will slip round to follow those who are trailing him. But in no other case that I know of has a bear lingered after he realized that he was seen. After Old Timberline discovered that I had circled behind him, he knew that I knew where he was and what he was doing. But instead of running away he came back along the trail to await my coming. What were his intentions? Did he intend to assault me, or was he overcome with curiosity because of my unusual actions and trying to discover what they were all about? I do not know. I concluded it best not to follow him farther, nor did I wish to travel that night with this crafty, soft-footed fellow in the woods. Going a short distance down among the trees, I built a rousing fire. Between it and a cliff I spent the night, satisfied that I had had adventure enough for one outing.
