which are seen at the sides of the square hole, in our
illustration, and also seen at (_c_), side view. These
[Page 118]
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 th
