opening of the arch. We will now go back to the sapling again.
It should be bent down slightly, and a piece of the strong twine
should be tied to its tip. Taking hold of the string, proceed to
bend down the end of the sapling, in the direction of the inclosure,
until it draws with a force strong enough to lift a rabbit if he
were tied to the end of it. Thus holding it down with the string
against the front of the inclosure, cut off the twine at the place
where it crosses the top of the arch, as this will be the required
length. It is now necessary to tie the end of this string to the
same piece of wood and at the same place to which the noose was
tied. When this is done the trap may be set as shown in the cut.
The spring sapling should be bent as seen in the first illustration.
The piece of wood holding the noose should be passed beneath the
top of the arch, as far as it will go, with its long end pointing
inside the inclosure. By now supporting the inside end with the
bait stick, and carefully adjusting the noose so as to completely
fill the arch, the trap will be set.

[Page 46]
In order to reach the bait, the rabbit or bird _must_ necessarily
pass its head through the noose, after which, if the bait be scarcely
_touched_, the animal's doom is sealed, and he is lifted into the
air, generally suffering almost instant death. It is well known
that in the case of a rabbit the neck is broken by a very slight
blow, a strong snap of the finger being often sufficient. It is
therefore safe to conclude that when thus suddenly caught and lifted
by the noose, death must occur almost instantaneously from the
same cause.

It is not really necessary to success that the force of the sapling
