should climb the tree to complete operations. For this purpose, a
smaller branch about three feet in length should be cut. One end
should be flattened off on both sides, so as to fit in the notch
in the beam; and the part which rests on the limb, as seen in the
illustration, should also be flattened to prevent turning. A piece
of stout Indian twine should next be fastened to the unwhittled end
of the stick, which may then be adjusted in the notch of the harpoon
beam, as seen in the engraving. The string may then be thrown down,
and grasped by the companion below, who holds it firmly, after
which the original rope may be removed. It will be noticed that the
weight of the harpoon and accompaniments rests on the short arm of
the lever which passes over the limb of the tree, and the tension on
the string from the long arm is thus very slight. This precaution
is necessary for the perfect working of the trap. To complete the
contrivance, a small peg with a rounded notch should be cut, and
driven into the ground directly plumb beneath the long end of the
lever. It should be inserted into the earth only sufficiently to
hold the string without pulling out, and the _side_ of the notch
should face the path; its height should be about a foot. Into the
notch the string should be passed, being afterwards drawn across
the path and secured on the opposite side at the same height. The
trap is now set; and woe to the unlucky quadruped that dares make
too free with that string! A very slight pressure from either side
is equally liable to slip the string from the notch, or loosen the
peg from the ground; and the result is the same in either case,--down
comes the weighted harpoon, carrying death and destruction to its
victim.

For large animals, this made of setting will be found to work perfectly.
When constructed on a smaller scale, it may be slightly modified.
