Autumn is the time when bears most search the heights for food. Old Timberline’s trail headed again for the heights. When I next caught sight of him, he was digging above the tree-line, but as it was now nearly night, I went back a short distance into the woods and built a fire by the base of a cliff. Here all through the clear night I had a glorious view of the high peaks up among the cold stars.

Before daylight I left camp and climbed to the top of a treeless ridge, thinking that the bear might come along that way. In the course of time he appeared, about a quarter of a mile east of me. After standing and looking about for a few minutes, he started along the ridge, evidently planning to recross the Continental Divide near where he had crossed the day before. As I could not get close to him from this point, I concluded to follow his trail of the preceding night and if possible find out what he had been doing.

A short distance below him I found his trail and back-tracked to a place which showed that he had spent the night near the entrance of a recently dug den. I learned some weeks later that this den was where he hibernated that winter. A short distance farther on I came to where he had been digging when I saw him the evening before. Evidently he had been successful. A few drops of blood on the snow showed that he had captured some small animal, probably a cony. From this point I trailed Old Timberline forward and eastward, and near noon I caught a glimpse of him on the summit of the Divide.

While roaming above timber-line he did not take the precaution to travel with his face in the wind. He could see toward every point of the compass. He was ambling easily along, but I knew that his senses were wide awake—that his sentinel nose never slept and that his ears never ceased to hear. Climbing to the very summit of a snow-covered ridge, he lay down with his back to the wind. Evidently he depended upon the wind to carry the warning scent of any danger behind him, while he was on the lookout for anything in front of him. Nothing could approach nearer than half a mile without his knowing it. He looked this way and that. After only a short rest he arose and started on again.

I hoped that some time I should be able to photograph Old Timberline at twenty-five or thirty feet. But at all times, too, I was more eager to watch him, to see what he was eating, where he went, and what he did. I was constantly trying to get as close as possible. Of course I had ever to keep in mind that he must not see, hear, nor scent me. I had to be particularly careful to prevent his scenting me. Often in hastening to reach a point of vantage I had to stop, note the topography, and change my direction, because a wind-current up an unsuspected cañon before me might carry news of my presence to the bear.

Near mountain-tops the wind is deflected this way and that by ridges and cañons. In a small area the prevailing west wind may be a north wind, and a short distance farther on it may blow from the southwest. Often, when the bear was somewhere in a cañon, I climbed entirely out of it, to avoid the likelihood of being scented, and scurried ahead on a plateau.

Usually I followed in the bear’s trail, but sometimes I made short cuts. So long as Old Timberline remained on the moorland summit of this treeless ridge, I could not get close to him. But when he arose and started down the ridge, I hurried down the slope, hoping to get ahead and hide in a place of concealment near which he might pass. I kept out of sight in the woods and hastened forward for two miles, then climbed up and hid in a rock-slide on the rim of the ridge.

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. Look ing 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.
