When the beaver's village is in a small creek, or brook, it is first necessary to stake the water across both above and below the huts. The next thing is to ascertain the exact spots of the burrows in the banks, and when we consider the river is covered with ice, this seems a rather difficult problem. But this is where the Indian shows his skill. He starts upon the ice, provided with an ice chisel secured to a long, stout handle. With this he strikes upon the ice, following the edge of the stream. The sound of the blow determines to his practiced ear the direct spot opposite the opening of the burrows, and at this point a hole a foot in diameter is made through the ice. Following the edge of the bank he continues his search, and in like manner cuts the holes through the ice until all the retreats are discovered. While the expert Indians are thus engaged, the "squaws" are occupied in the more laborious work of breaking open the houses, and the beavers, alarmed at the invasion of their sanctums, make for the banks, and the ready huntsmen stationed at the various holes, watch for their victims beneath the openings, until a violent motion or discoloration of the water betrays their passage beneath. The entrance to the holes in the bank are then instantly closed with stakes and the beaver is made prisoner in his burrow. When the depth of the burrow will admit, the arm of the hunter is introduced, and the animal pulled out, but otherwise a long hook lashed to a pole is employed for this purpose. Scores of beavers are sometimes taken in this way in a few hours. Spearing is also often successfully resorted to, and when the ice is thin and transparent the beavers may be clearly observed as they come to the surface, beneath the ice, for air.
The general color of the animal is reddish brown, this tint being imparted principally by the long hairs of the fur. There is an inner and softer down of a grey color, which lies next the skin, and which is the valuable growth of the fur. The total length of the animal is about three feet and a half, the flat, paddle-shaped, scale-covered tail being about a foot in length.
The young are brought forth in April or May, from three to seven at a litter, and take to the water when a month old. The first four years in the beaver's life is spent under the "maternal roof," after which period they shift for themselves. To trap the beaver successfully, requires the utmost caution, as the senses of the animal are so keen, and he is so sagacious withal, that he will detect the recent presence of the trapper from the slightest evidences. The traps should be washed clean and soaked in ley, before using, and thereafter handled with gloves, as a mere touch of the finger will leave a scent which the acute sense of the beaver will easily perceive. All footprints should be carefully obliterated by throwing water upon them, and some trappers say that the mere act of spitting on the ground in the neighborhood of the traps has been known to thwart success.
Almost the only bait used in trapping the beaver is the preparation called "barkstone" by the trappers, or "castoreum" in commerce. This substance is fully described on [page 150] under the head of "Scent Baits."
To the barkstone the trapper is mostly indebted for his success, and the effect of its odor on the beaver is something surprising. Our best trappers inform us that these animals will scent this odor for a great distance, and will fairly "squeal with delight," not being easy until the savory bait is discovered, which almost invariably results in capture.
Taking advantage of this curious propensity, the trapper always carries a supply of castoreum in a closed vessel.
There are various ways of trapping the beaver, of which we shall present the best. An examination of the river bank will easily disclose the feeding place of the beavers, as evinced by the absence of the bark on the branches and trunks of trees. At this spot, in about four inches of water, set your trap, which should be a Newhouse No. 4. Weight the end of the chain with a stone as large as your head, and, if possible, rest it on the edge of some rock projecting into deep water, having a smaller rope or chain leading from the stone to the shore. A small twig, the size of your little finger, should then be stripped of its bark, and after chewing or mashing one end, it should be dipped in the castoreum. Insert this stick in the mud, between the jaws of the trap, letting it project about six inches above the water. The beaver is soon attracted by the odor of the bait, and in reaching for it, his foot is caught in the trap. In his fright he will immediately jump for deep water, thus dislodging the stone, which will sink him to the bottom, and thus drown him. The smaller chain or rope will serve as a guide to the trap, and the victim may be drawn to the surface. Another plan is to set the trap in about a foot of water, chaining it fast to a stout pole securely driven in the mud further out in the stream, and near deep water. Bait as before. The trap being thus fastened will prevent the efforts of the animal to drag it ashore, where he would be certain to amputate his leg and walk off. There is another method, which is said to work excellently. The chain is secured to a very heavy stone, and sunk in deep water, and the trap set and baited near shore, in about a foot of water. This accomplishes the same purpose as the pole first described, and is even surer, as the animal will sometimes use his teeth in severing the wood, and thereby make his escape. In the case of the stone a duplicate rope or chain will be required to lift it in case of capture.
The trap may be set at the entrance to the holes in the banks, two or three inches under water, implanting the stick with the castoreum bait directly over the pan, a few inches above the water. If the water should be deep near this spot, it is an excellent plan to weight the end of the chain with a large stone with a "leader" from it also, as already described. Insert two or three sticks in the bank beneath the water, and rest the stone upon them.
When the beaver is caught he will turn a somersault into deep water, at the same time dislodging the stone, which will sink him. No sooner is a break ascertained in the dam than all the beavers unite in fixing it, and this peculiarity of habit may be turned to account in trapping them. Make a slight break in the dam, five inches across, beneath the water. On the under side of the break, and of course, on the inside of the dam, the trap should be set. The beavers will soon discover the leak and the capture of at least one is certain. The trap may be also set where the beavers are wont to crawl on shore, being placed several inches below the water in such a position that they will step on it when in the act of ascending the banks. Where the weighted stone is not used, the sliding pole [page 145] should always be employed, as it is necessary to drown the animal, to prevent amputation and escape.
The food of the beaver consists chiefly of the bark of various trees, together with aquatic plants. The fur is valuable only in the late fall, winter, and early spring.
