burrow in the ground.
>It is an object of the invention to provide an
improved combined body-gripping and body
piercing or impaling means, so that when the trap
is released the body of the animal willbe both
pierced and gripped thus making it doubly sure
that it Will not escape from the trap.
Another object relates to the provision of an
improved relative positioning of the trigger of the
trap in relation to the body-gripping and body
piercing members so that, when the animal re
leases the trigger, its body will at such time be
positioned directly in the path of the spring
actuated body-gripping and body-piercing means.

pointed hooks I6 being shown spaced 120 Ydegrees
apart. One end of spring I4 bears against shank
