Very soon one of the boys aroused the bear and started him running. The grizzly had evidently scented him half a mile away. Running in my direction, when within about a mile he discovered my presence, turned, and retreated six or seven miles into a remote corner of his territory. In this retreat he did not go within two miles of either of the other fellows. Realizing that the bear had eluded us, we slightly separated and moved toward him. He did not wait to be cornered in a cañon. Late that day we followed his devious tracks and discovered his movements. We learned to our chagrin that he had doubled back in the cañon and come part way toward us. Then, climbing an out-thrusting ridge where he could see in all directions, he evidently had watched us when we passed up a grassy valley beneath him. After we were in the timber beyond he had descended to the valley. Then the most amazing turn came. Instead of running away in the opposite direction he had followed along close behind us! By the time we discovered all this the day was gone, and so was the bear. He had had an adventure. Did the grizzly know we were unarmed? He might have used the same tactics in any case. Anyway, he easily kept out of our way, followed our moves, and had, perhaps, enjoyed our unsuccessful efforts. I would give the grizzly first place in the animal world for brain-power. He is superior in mentality to the horse, the dog, and even the gray wolf. Instinct the grizzly has, but he also has the ability to reason. His ever-alert, amazingly developed senses are constantly supplying his brain with information--information which he uses, and uses intelligently. His powers of scent are exquisite. His ears hear faint sounds; they are continually on scout and sentinel duty. Wireless messages from long distances which his senses pick up are accurately received and their place of origin correctly determined. The grizzly appears to guide his daily life with plan and forethought. He has the genius for taking pains. He is constantly alert and meets emergencies with brains. The following actions have impressed me with his keen mental processes. A grizzly cub in Yellowstone Park found a big ham skin--a prized delicacy. Just as the little fellow was lifting it to his mouth a big bear appeared. He instantly dropped the ham skin, sat down on it, and pretended to be greatly interested in watching something in the edge of the woods. Another young grizzly in the Yellowstone one day found a tin can that was open at one end and partly filled with fish. He raised it in his fore paws and peeped in, then deliberately turned the can upside down and shook it. Nothing came out. He shook again; no result. Then he proceeded just about as you or I might have done. He placed the can on the ground, open end down, and hammered the bottom of the can with a stone until the fish dropped out.
