THE SPRING NET TRAP.
Although slightly complicated in construction, our next illustration presents one of the prettiest bird traps on record, and may be made in the following manner, and by frequently referring to the picture, our explanation will be easily understood.
The first step is to make or procure a low flat box, about fifteen inches long, by ten inches in width, with a depth of about two inches. Next fasten an interior box, of the same height, leaving a space of about three-quarters of an inch between them all round. A platform should now be made. Let it be of such a size that it will just fit in the interior box, with a very slight space all around its edge. It should then be pivoted in the upper part of this box by two small slender pins, one being driven through into its edge, at the centre of each end. Let it be sensitively poised. The next thing to be done, is to arrange the spindle and catch. The latter should consist of a tack or small bit of wood fastened on the middle of the platform, about an inch from one end, as seen both in the main illustration and in the diagram at (b).
The spindle should consist of a flat piece of wood, secured with a leather hinge to the edge of the outside box, directly opposite
the catch. Let it be long enough to reach and barely hold itself beneath the catch. When thus in its position, two small plugs should next be driven into the edge of the inner box, one on each side of the spindle, thus holding it in place. A glance at our illustration makes this clear. The netting and "hoop" are next in order. The hoop should consist of an iron wire of the diameter of common telegraph wire.
For a box of the size we have given, a length of about twenty-eight inches will be found to answer. Before making the hoop, however, its hinges should be ready for it. Two screw eyes, or staples of bent wire should be driven into the bottom of the box between the two walls, one in the exact middle of each side. The iron wire should now be bent so as to fit round and settle into the space between the boxes, letting each end rest over the screws in the bottom. It will be found that there will be enough surplus wire on each end to form into a loop with the pincers. These loops should be passed through the screws or rings already inserted, and then pinched together; the hinge will thus be made, and will appear as at (c). If properly done, they should allow the hoop to pass freely from one end of the box to the other, and settle easily between the partitions. If this hinge should prove too complicated for our young readers, they may resort to another method, which, although not so durable, will answer very well. In this case the wire will only need to reach to the exact middle of the long sides. No surplus being necessary, a length of twenty-six inches will be exactly right. On each end a short loop of tough Indian twine should be tied. By now fastening these loops to the bottom of the box with tacks, in the place of screws, it will form a hinge which will answer the purpose of the more complicated one.
The netting should consist of common mosquito gauze, or, if this cannot be had, any thin cloth may be substituted. It should be sewed fast to the iron wire, from hinge to hinge, and then, with the hoops resting in its groove, the netting should be drawn over the platform, and tacked to the bottom of the groove, on its remaining half. It should rest loosely over the platform to allow plenty of space for the bird.
But one more addition, and the trap is finished. We have mentioned the use of elastics in other varieties: they are of equal use here, and should be attached to the hoop as seen at (a) in the section drawing, the remaining ends being fastened to the bottom of the groove, as there indicated. These elastics should be placed on both sides, and stretched to such a tension as will draw the hoop quickly from one side to the other.
It will now be easy to set the trap. Draw the hoop back to the opposite end, tucking the netting into the groove; lower the spindle over it, resting it between the two little plugs, and securing its end beneath the catch on the platform. If the bait, consisting of bread-crumbs, berries, insects, or the like, be now sprinkled on the platform, the trap is ready for its feathered victim. It will easily be seen that the slightest weight on either side of this poised platform will throw the catch from the end of the spindle, and release the hoop and the platform in an instant is covered by the net, capturing whatever unlucky little bird may have chanced to jump upon it. This is a very pretty little trap, and will well repay the trouble of making it.
