Under some thick evergreen tree, scrape up a cone shaped pile of snow, making it two feet high and pack the snow solid. Have the trap fastened to a clog and bury the clog in the snow. In the very top of the mound, hollow out a place for the trap and line this place with evergreen tips. Set the trap in this nest, cover it with a piece of paper, and brush a half inch of snow lightly over the paper. For bait, use a whole partridge or rabbit and hang it by a string from a limb of the tree, so that it hangs about two and a half feet above the trap.
Brush your tracks shut with a bunch of boughs and when looking at the trap do not go too close. This method is very good for the shy ones but is too much trouble to use as a regular set, when putting out a long line of traps. The best places in which to set for fishers is in the timbered ravines, especially where two ravines join. Other good places are at the ends of lakes, the points of swamps, and in narrow strips of timber connecting larger bodies.
The track of the fisher is very similar to that of the marten but is larger. The length of jump is about three feet and the footprints from one and a half to two inches in length.
