Having determined upon the locality of his trapping-ground, the hunter started off, sometimes alone, sometimes three or four of them in company, as soon as the breaking of the ice in the streams would permit, if he was to go very far north. Arriving on the spot he has selected for his permanent camp, the first thing to be done, after he had settled himself, was to follow the windings of the creeks and rivers, keeping a sharp lookout for "signs." If he saw a prostrate cottonwood tree, he carefully examined it to learn whether it was the work of beaver, and if so whether thrown for the purpose of food, or to dam the stream. The track of the animal on the mud or sand under the banks was also examined; if the sign was fresh, he set his trap in the run of the animal, hiding it under water, and attaching it by a stout chain to a picket driven in the bank, or to a bush or tree. A float-stick was made fast to the trap by a cord a few feet long, which, if the animal carried away the trap, would float on the water and point out its position. The trap was baited with "medicine," an oily substance obtained from the beaver. A stick was dipped in this and planted over the trap, and the beaver, attracted by the smell, put his leg into the trap and was caught.
When a beaver lodge was discovered, the trap was set at the edge of the dam, at a point where the animal passed from deep to shoal water, and always under the surface. Early in the morning, the hunter mounted his mule and examined all his traps.
The beaver is exceedingly wily, and if by scent or sound or sight he had any intimation of the presence of a trapper, he put at defiance all efforts to capture him, consequently it was necessary to practise great caution when in the neighbourhood of one of their lodges. The trapper then avoided riding for fear the sound of his horse's feet might strike dismay among the furry inhabitants under the water, and, instead of walking on the ground, he waded in the stream, lest he should leave a scent behind by which he might be discovered.
In the days of the great fur companies, trappers were of two kinds--the hired hand and the free trapper. The former was hired by the company, which supplied him with everything necessary, and paid him a certain price for his furs and peltries. The other hunted on his own hook, owned his animals and traps, went where he pleased, and sold to whom he chose.
