and shoe soles to conceal the human odor.

If the animals become “wise” to this kind of scent, an effective fish scent may be prepared in the following way:

Grind the flesh of sturgeon, eels, trout, suckers, carp, or other oily variety of fish in a sausage mill, place in strong tin or iron cans, and leave in a warm place of even temperature to decompose thoroughly. Provide each can with a small vent to allow the escape of gas (otherwise there is danger of explosion), but screen the aperture with a fold of cloth to prevent flies depositing eggs, as the scent seems to lose much of its quality if many maggots develop. This scent may be used within 3 days after it is prepared, but it is more lasting and penetrating after a lapse of 30 days. It is also very attractive to livestock, and its use on heavily stocked ranges is not recommended, as cattle are attracted to such scent stations and will spring the traps.

An excellent system for a hunter to follow is to commence with a quantity of ground fish placed in large iron containers, similar to a milk can. As the original lot is used on the trap line, it should be replenished by adding more ground fresh fish. The addition from time to time of new material seems to improve the quality of the scent mixture.

Where no moisture has fallen, rescenting of scent posts need be done only every four or five days. In wet weather every third day is good practice. For dropping the scent it is best to use a 2 to 4 ounce shaker-corked bottle.

The actual trapping of a wolf or a coyote by the method here described occurs when the animal comes over its runway and is attracted to the “post” by the scent that has been dropped. In approaching the spot for a smell the animal invariably puts a foot on the concealed pan; the jaws are thus released and the foot is securely held. The place where a wolf or a coyote has thus been caught affords an excellent location for a reset after the animal has been removed from the trap. This is due to the natural scent dropped by the animal while in the trap.

It is advisable always to wear gloves while setting traps and to use them for no other purpose than for trap setting.
