For the capture of mice this is both a simple and effective contrivance,
and it may be enlarged so as to be of good service for larger animals.
Procure two boards, one foot square and one inch thick, and secure
them together by two hinges, as in the illustration. Assuming one
as the upper board, proceed to bore a gimlet hole three inches
from the hinges. This is for the reception of the bait stick, and
should be cut aw
y on the inside, as seen in the section (a),
thus allowing a free play for the stick. Directly beneath this
aperture, and in the lower board, a large auger hole should be made.
A stout bit of iron wire, ten inches in length, is now required.
This should be inserted perpendicularly in the further end of the
lower slab, being bent into a curve which shall slide easily through
a gimlet hole in the edge of the upper board. This portion is very
important, and should be carefully constructed. The bait stick
should be not more than three inches in length, supplied with a
notch in its upper end, and secured in the aperture in the board by
the aid of a pivot and staples, as is clearly shown in our drawing.
The spindle is next in order. It should consist of a light piece
of pine eight and a half inches in length, and brought to an edge
at each end. A tack should now be driven at the further edge of
the upper board on a line with the aperture through which the wire
passes. Our illustration represents the trap as it appears when
set. The upper band is raised to the full limit of the wire. One
end of the spindle is now adjusted beneath the head of the tack,
and the other in the notch in the bait stick. The wire thus supports
the suspended board by sustaining the spindle, which is held in
equilibrium. A slight touch on the bait stick soon destroys this
equilibrium: a flap ensues, and a dead mouse is the result. The
object of the auger hole in the lower board consists in affording a
receptacle for the bait when the boards come together, as otherwise
it would defeat its object, by offering an obstruction to the fall
of the board, and thus allow its little mouse to escape.
It is, therefore, an essential part of the trap, and should be carefully
tested before being finally set.
