If the pole for the fall is larger than the notch is deep, the end must be flattened so that it will work easy in the notch, as a piece of wood has been nailed over the notch to hold the fall pole in place.
The triggers used are generally the figure 4 and set with bait pointing as shown. There is no place for the marten to stand while eating bait, only in shelf, and of course when the spindle is pulled, down comes the pole killing the animal.
TREE DEADFALL.
This shelf protects the bait and bed piece and the snow does not fill in between and require so much attention as the one first described.
This deadfall may also be built on a stump with a small enclosure or pen and the two-piece trigger used. Most trappers place the bait or long trigger on bottom pole, when trapping for marten. It will be readily seen that a marten, to get the bait, will stand between the "fall" and bed or under pole and of course is caught while trying to get the bait.
