Trapping the grizzly has become a non-essential occupation. It is a waste of energy, because rarely successful. Now and then a bear is trapped, but it is usually a young bear of but little experience, a mother who is trying to protect her cubs, or a bear whose momentary curiosity caused him to forget his customary caution. Formerly it was not difficult to trap a grizzly. But he quickly learned to avoid the menace of traps. The bear sees through all the camouflage of the trapper. Deodorized and concealed traps, traps near the bait and far from it, traps placed singly and in clusters--these, and even the slender concealed string of a spring gun, he usually detects and avoids. I spent a number of days with a trapper who felt certain that he would secure the thousand-dollar reward for the capture of an outlaw cattle-killing grizzly. Earlier than usual the cattlemen drove the cattle from the summer range. The trapper took an old cow to a selected spot near the end of a gulch, picketed her, and surrounded her with spring guns and traps. The outer line of defense consisted of three spring guns which guarded three avenues of approach to the cow. The strings to these guns were of silk line stretched over bushes and tall grass so as to be inconspicuous. As the bear would be likely to seize the cow's head or neck, a trap was set between her head and a large bowlder near by. There was a trap on each side of the cow and one behind her. The first night there was a light fall of snow, but no bear. But the second night he came. Tracks showed that he scented or heard the cow from afar--more than a mile away--and came straight for her. He stopped within two feet of the silk line and walked cautiously round it until he completed the circuit. But there was no opening. He then leaped the line--something I had never before heard of a bear doing. He approached the cow, then walked round her; he went close to the traps and detected just where each one was concealed. Then, between the trap in front and the one on the left, he seized and killed the cow. After feeding on her he dragged the carcass across two traps and left it. Leaping the line again, he went off down stream in the gulch. The trapper reset the traps the following day and placed an additional one just inside the line, at the point where the grizzly had leaped over it. Then, some distance down stream, he strung a line across the gulch and attached a spring gun to one end of the line.
