required. This should be large enough to cover the opening, and
should be made of stout board slabs, firmly secured by cross pieces.
It should be made to slide smoothly into grooves cut into perpendicular
logs situated on each side of the opening, or may be arranged to
slip easily between the flattened side of one log on each side
and the front of the pen. Either way works well. In the latter
an additional upright or short board should be inserted in the
ground at the edges of the sliding door, to prevent the latter
from being forced to either side by the efforts of the enclosed
captive.

There are two or three ways of setting the trap, depending upon
the desired game. For a bear it is arranged as in our illustration.
An upright post, two feet in length, should be cut
[Page 31]
to an edge at one end, and wedged in between the logs at the top
of the trap, near the middle. Across the top of this, a pole seven
feet in length, should be rested; one end being attached by a loop,
or secured in a notch in the sliding door, and the other supplied
with a strong string about four feet in length, with a stick eight
inches in length secured to its end. Through the centre log, in
the back of the pen, and about two feet from the ground, an auger
hole should be made. The bait stick with bait attached should be
inserted through this hole from the inside, and the spindle caught
on the outside between its projecting end and a nail driven in
the adjoining upright. This principle is clearly illustrated on
page 105 at (_a_), and, if desired, the method (_b_) may be used
also. For a bear, the bait should consist of a piece of meat scented
