Another very good method is the following: Find a small spruce, about three inches in diameter and cut the tree about two feet above the snow, leaving the top of the stump V shape. Draw the tree forward and lay it over the stump, so that the butt of the tree will be three or three and a half feet above the snow. Now, about a foot back from the end, flatten off a place for the trap and set the trap on the pole. Tie the trap fast with a light string and loop the chain around the tree. Split the butt of the tree, and fasten the bait in the split. This is a very good set, possessing advantages over most methods. The birds can not eat the bait, the trap is not bothered by weasels or rabbits, the marten must stand on the trap when trying to get the bait, and when caught, falls off the pole and can not get back.
In the mountains, where the snow falls deep, the traps are set on the trees, five or six feet above the snow. The most common way, is to make two cuts in the tree with an axe, and drive in two wooden pegs, about five inches apart. Set the trap and place it on the pegs, one peg passing through the bow of the spring, the other between the jaws and the bottom of the trap. Draw the chain around the tree and staple solidly. The bait is pinned to the tree, about a foot above the trap. A bunch of boughs may be placed over the bait to hide it from the birds.
If desired, a notch may be cut in the tree and a trap set in the notch. The notch should be about four inches deep and about twelve inches from top to bottom. Cut the bottom smooth, so the trap will set solid and fasten the bait in the top of the notch. Staple the trap to the tree. If desired, you can lean a pole against the tree for the marten to run up on, but this is not necessary.
The trapper should always be on the lookout for places in which the trap may be set without much labor. Sometimes a tree can be found, with a hollow in one side and this makes a good place for a set. Lean a pole against the tree, with one end resting in the hollow, set a trap on the pole and place a bait in the cavity above the trap. At other times a cavity may be made in the side of a rotten stub and a trap set in the same way. The traps recommended for marten are the No. 1 of any make, but the No. 0 Newhouse is much used. If there are fishers, lynx and other large animals about, it is best to use a No. 1 1/2 trap. Deadfalls are also used and they may be built on the ground or snow, or on the top of a stump, or the side of a tree. The track of the marten resembles that of the mink, except that it is a trifle larger and the footprint wider in proportion to the length. The toes do not make as clear a print as do those of the mink, the feet being more heavily furred.
