By and by I saw Old Timberline coming. When within five hundred feet of me he stopped and dug energetically. Buckets of earth flew behind, and occasionally a huge stone was torn out and hurled with one paw to the right or left. Once he stopped digging, rose on hind feet, and looked all around as though he felt that some one was slipping up on him. He dug for a few minutes longer and then again stood up and sniffed the air. Not satisfied, he walked quickly to a ledge from which he could see down the slope to the woods. Discovering nothing suspicious, he returned to his digging, stepping in his former footprints. He uncovered something in its nest, and through my glasses I saw him strike right and left and then rush out in pursuit of it. After nosing about in the hole where he had been digging, he started off again. He went directly to the ledge, walking in his former well-tracked trail, then descended the steep eastern slope of the Divide toward the woods. I hurried to the ledge from which he had surveyed the surroundings and watched him. Arriving at a steep incline on the snowy slope, Old Timberline sat down on his haunches and coasted. A grizzly bear coasting on the Continental Divide! How merrily he went, leaning forward with his paws on his knees! At one place he plunged over a snowy ledge and dropped four or five feet. He threw up both fore paws with sheer joy. Soon he found himself exceeding the speed-limit. Looking back over one shoulder, and reaching out his paw behind him, he put on brakes; but as this did not check him sufficiently, he whirled about and slid flat on his stomach, digging in with both fingers and toes until he slowed down. Then, sitting up on his haunches again, he set himself in motion by pushing along with rapid backward strokes of both fore paws. He coasted on toward the bottom. In going down a steep pitch of one hundred feet or more he either quite lost control of himself or let go from sheer enthusiasm. He rolled, tumbled, and slid recklessly along. Reaching the bottom, he rose on hind feet, looked about him for a few seconds, and then climbed halfway up the course for another coast. At the end of this merry sliding he landed on an open flat in the edge of the woods. As it was nearly dark and I should not be able to see or follow the bear much longer, I concluded to roll a rock from the ledge down near him. Twice I had noticed that he had paid no attention to rocks that broke loose above and rolled near him. But he heard this rock start and rose up to look at it. It stopped a few yards from him. He sniffed the air with nose pointing toward it and then went up and smelled it. Rearing up instantly, he looked intently toward the mountain-top where I was hidden. After two or three seconds of thought he turned and ran. Evidently the stone had carried my scent to him. It was useless to follow him in the night.
