Spread of Jaws, 3 1/2 inches. This, the smallest trap made, is used mostly for catching the gopher, a little animal which is very troublesome to western farmers, and also rats and other vermin. It has a sharp grip and will hold larger game, but should not be overtaxed.
Spread of Jaws, 4 inches. This Trap is used for catching muskrats and other small animals, and sold in greater numbers than any other size. Its use is well understood by professional trappers and it is the most serviceable size for catching skunks, weasels, rats and such other animals as visit poultry houses and barns.
Spread of Jaws, 4 inches. Occasionally animals free themselves from traps by gnawing their legs off just below the trap jaws, where the flesh is numb from pressure. Various forms of traps have been experimented with to obviate this difficulty. The Webbed Jaws shown above have proved very successful in this respect.
Noting the cross-section of the jaws, as illustrated at the left, it is plain the animal can only gnaw off its leg at a point quite a distance below the meeting edges. The flesh above the point of amputation and below the jaws will swell and make it impossible to pull the leg stump out of the trap.
The No. 81 Trap corresponds in size with the regular No. 1 Newhouse.
