THE SPRING POLE.
This is nearly always used in connection with the steel trap, in the capture of the smaller land animals. It not only lifts the creature into the air, and thus prevents its becoming a prey to other animals, but it also guards against the escape of the victim by the amputation of its own leg. This is a very common mode of release with many kinds of game—notably the mink, marten, and muskrat; and for the successful trapping of these, as well as many other animals, the spring and sliding pole are absolute necessities. It is a simple contrivance, consisting merely of a pole inserted in the ground near the trap. The pole is then bent down, and the trap chain secured to its end. A small, notched peg is next driven into the ground and the top of the pole caught in it, and thus held in a bent position. When the animal is caught, its struggles release the pole, and the latter, flying up with a jerk, lifts the trap and its occupant high in the air, out of the reach of marauders, and beyond the power of escape by self-amputation. Even in the capture of large game the spring pole often serves to good purpose. The struggles of a heavy animal are often so violent
as to break a stout trap or chain; and the force of the spring pole, although not sufficient to raise the animal from its feet, often succeeds in easing the strain, and often thus saves a trap from being broken to pieces. The power of the pole must of course be proportionate to the weight of the desired game.
