The grizzly returned that night, coming down the gulch. After walking the lines around the carcass, and apparently having detected the new trap inside, he leaped the line at another point. He avoided the traps and ate about half the remainder of the carcass. Then he piled a few dead logs on what was left, leaped the line again, and went down the gulch. He stopped within ten or twelve feet of the line here and followed it along to where it connected with the rifle on the side of the gulch. Walking round the rifle, he went back into the gulch and followed his trail of the preceding night. The trapper, amazed, vowed vengeance. He made haste and built a log pen around the remains of the carcass. He then set two traps in the entrance of the pen, one in front of the entrance and one inside the pen. The second night following, the bear returned, leaped over the line, and cautiously approached the pen. The bowlder formed part of the rear end of this. Climbing on top of the bowlder, the bear tore off the upper part of the pen, which rested on the bowlder, and then, from the bowlder, without getting into the pen, reached down and dragged up the carcass. In doing this one of the poles which had been torn out of place and thrown to one side struck the top of a stump, turned over, and fell across the line attached to a spring gun. This fired its waiting shot. Then the grizzly did this astounding thing. He appears to have been on top of the bowlder when the shot was fired, but he descended, made his way to the smelly gun, and then examined it, the snow being tracked up in front of it. Returning to the carcass, he dragged it off the bowlder and ate the last mouthful. Leaving the bones where they lay, he walked across the line where the pole rested on it and went off up the gulch. A grizzly is wary for the preservation of his life. It is generally a triumph of stalking to get within short range of him. His senses detect danger afar. He will sometimes hear the stealthy approach of a hunter at the distance of a quarter of a mile, and under favorable conditions he will scent a man at a distance of a mile or more. Being ever on guard, and generally in a place where he can scout with scent, sight, or hearing, he usually manages to keep out of range or under cover. It is not uncommon for two or three hunters in different parts of bear territory, searching with field-glasses, watching from high places, taking advantage of the wind, and moving silently, to spend a week without even seeing a bear, although bears were about. Many times, even when trailed with dogs, through his brains, his endurance, and his ability to move rapidly over rough territory, the grizzly escapes being cornered.
