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.
Spread of Jaws--#91, 5 1/4 inches; #91 1/2, 6 1/4 inches. The double jaws take an easy and firm grip so high up on the muskrat that he can not twist out. A skunk cannot gnaw out either.
These traps are especially good for Muskrat, Mink, Skunk and Raccoon.
All parts of the No. 91 except the jaws are the same size as the regular No. 1 Newhouse, while the 91 1/2 corresponds to the regular No. 1 1/2.
Spread of Jaws, 4 7/8 inches. This size is called the Mink Trap. It is, however, suitable for catching the Woodchuck, Skunk, etc. Professional trappers often use it for catching Foxes. It is very convenient in form and is strong and reliable.
