THE PENDENT BOX TRAP.
This invention is original with the author of this work, and when properly made and set will prove an excellent device for the capture of small birds.
The general appearance of the trap, as set, is clearly shown in our illustration. A thin wooden box is the first requisite, it should be about a foot square and six inches in depth, and supplied with a close fitting cover, working on hinges. The sides should then be perforated with a few auger holes for purposes of ventilation.
Two elastics are next in order, and they should be attached to the cover and box, one on each side, as shown at (a.) They should be drawn to a strong tension, so as to hold the cover firmly against the box.
The mechanism of the trap centres in the bait stick which differs in construction from any other described in this book.
It should be made about the size of a lead pencil, and eleven inches or so in length, depending of course upon the size of the box.
It should then be divided in two pieces by a perfectly flat cut, the longer part being six inches in length. This piece should be attached to the back board of the box by a small string and a tack, as shown at (c), its end being bluntly pointed. Its attachment should be about five inches above the bottom board, and in the exact centre of the width of the back.
Near the flat end of the other piece the bait consisting of a berry or other fruit, should be secured, and the further extremity of the stick should then be rounded to a blunt point. The trap is now easily set. Raise the lid and lift the long stick to the position given in the illustration. Adjust the flat end of the bait stick
against that of the former, and allow the pressure of the lid to bear against the blunt point of the short stick at (d), as shown in the illustration, a straight dent being made in the cover to receive it, as also in the back of the box for the other piece. If properly constructed, this pressure will be sufficient to hold the sticks end to end, as our engraving represents, and the trap is thus set. The slightest weight on the false perch thus made will throw the parts asunder, and the cover closes with a snap.
The greatest difficulties in constructing the trap will be found in the bearings of the bait sticks (b), the ends of which must be perfectly flat and join snugly, in order to hold themselves together. The box may now be suspended in a tree by the aid of a string at the top. The first bird that makes bold enough to alight on the perch is a sure captive, and is secured without harm. If desired, the elastic may be attached to the inside of the cover, extending to the back of the box, as seen in the initial at the head of this chapter. If the elastic in any event shows tendencies toward relaxing, the tin catch described on [page 88] should be adjusted to the lower edge of the box to insure capture.
