THE BOW TRAP.
This most excellent and unique machine is an invention of the author's, and possesses great advantages, both on account of its durability and of the speedy death which it inflicts.
Procure a board about two feet in length, by five or six in width, and commencing at about nine inches from one end, cut a hole four or more inches square. This may readily be done with a narrow saw, by first boring a series of gimlet holes in which to insert it. There will now be nine inches of board on one side of the hole and eleven on the other. The shorter end constituting the top of the trap. On the upper edge of the hole a row of stout tin teeth should be firmly tacked, as seen in the illustration. On the other side of the cavity, and three inches from it a small auger hole (the size of a lead pencil), should be bored. After which it should be sand-papered and polished on the interior, by rubbing with some smooth, hard tool, inserted inside. A round plug of wood should next be prepared. Let it be about half an inch in length, being afterwards bevelled nearly the whole length of one side, as shown at (b), leaving a
little over an eighth of an inch of the wood unwhittled. This little piece of wood is the most important part, of the trap, and should be made very carefully. The remaining end of the board below the auger hole should now be whittled off to a point, in order that it may be driven into the ground. The next requisites consist of two pieces of wood, which are seen at the sides of the square hole, in our illustration, and also seen at (c), side view. These pieces should be about six inches in length and about an inch square. A thin piece being cut off from one side of each, to the distance of four inches, and ending in a square notch. The other end should be rounded off, as is also there plainly indicated. Before adjusting the pieces in place, two tin catches should be fastened to the board, one on each side of the hole. This catch is shown at (d), and consists merely of a piece of tin, half an inch in width, and three-quarters of an inch in length, tacked to the wood, and having its end raised, as indicated. Its object is to hold the bow-string from being pulled down after once passing it. The upper edge of these catch-pieces should be about an inch and a half from the top of the hole, and, if desired, two or three of them may be arranged one above the other, so that wherever the string may stop against the neck of the inmate it will be sure to hold. The catches being in place, proceed to adjust the pieces of wood, letting the notch be on a line with the top of the pole, or a little above it. Each piece should be fastened with two screws to make secure.
We will now give our attention to the bait stick. This should be about six inches in length, and square, as our illustration shows. There are two ways of attaching the bait-stick to the board, both shown at (e) and (f). The former consists merely of a screw eye inserted into the end of the stick, afterwards hinged to the board by a wire staple. The point for the hinge, in this case, should be about an inch below the auger hole. In the other method (f), the bait stick should be a half inch longer, and the spot for the hinge a quarter inch lower. At about a quarter of an inch from the square end of the bait stick a small hole should be made by the use of a hot wire. An oblong mortice should next be cut in the board, so as to receive this end of the stick easily. A stout bit of wire should then be inserted in the little hole in the stick, and laying this across the centre of the mortice, it should be thus secured by two staples, as the drawing shows. This forms a very neat and simple hinge. To determine the place for the catch, insert the flat end of the little plug fairly into the auger-hole above the hinge. Draw up the bait stick, and at the point where it comes in contact with the point of the plug, cut a square notch, as shown in (b). Everything now awaits the bow. This should be of hickory or other stout wood; it is well to have it seasoned, although a stout sapling will answer the purpose very well. It should be fastened to the top of the board by two heavy staples, or nails driven on each side of it. The string should be heavy Indian twine. Our illustration shows the trap, as it appears when ready for business. The plug is inserted, as already described, with the bevelled face downward, and square end in the hole. Draw down the bow-string and pass it beneath the plug, at the same time catching the tip of the latter in the notch of the bait stick. If properly constructed the string will thus rest on the slight uncut portion of the under side of the peg, and the trap is thus set. If the bait is pushed when approached, the notch is forced off from the plug, and the string flies up with a twang! securing the neck of its victim, and producing almost instant death. If the bait is pulled, the bait stick thus forces the plug into the hole in the board, and thus slides the cord on to the bevel, which immediately releases it, and the bow is sprung. So that no matter whether the bait is pushed or drawn towards the front, the trap is equally sure to spring.
In setting this curious machine, it is only necessary to insert it into the ground, and surround the bait with a slight pen, in order that it may not be approached from behind. By now laying a stone or a pile of sticks in front of the affair, so that the bait may be more readily reached, the thing is ready. Care is required in setting to arrange the pieces delicately. The plug should be very slightly inserted into the auger hole, and the notch in the bait stick should be as small as possible, and hold. All this is made clear in our illustration (b).
By observing these little niceties the trap becomes very sure and sensitive.
Bait with small apple, nub of corn, or the like.
