Only one pole is needed for this trap as the bottom of the notch cut answers for the bed or bottom piece. (See illustration.) The pole for the fall should be four inches or more in diameter and anywhere from six to ten feet in length, depending upon the place selected to set. The end fartherest from the bait or notched tree must be as high as the notch. This can be done by driving a forked stake into the ground or by tying that end of the pole to a small tree if there is one growing at the right place. [Illustration: HIGH BUILT MARTEN DEADFALL.] 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. [Illustration: 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. [Illustration: MORE MARTEN TRAP TRIGGERS.] The height that deadfalls for marten should be built depends upon how deep the snow gets. In the fall and early winter they can be built on the ground or logs and other fur-bearers are taken as well. A few inches of snow will not interfere with the workings of deadfalls on the ground, but deep snows will. To make catches the trapper must clean out under the fall pole each round. This is no small task. The trapper is always on the lookout for suitable places to construct Marten deadfalls. When the snows get several feet deep, and the trapper makes his rounds on snowshoes, the deadfalls constructed several feet above the ground are the ones that make the catches. CHAPTER V. STONE DEADFALLS. The stone deadfall here described is used by trappers wherever flat stones can be found and is a good trap to catch skunk, opossum, mink and other small game in. The trap is made as follows:
