It’s from a great little book called Bushcraft by Richard Graves. The book is recently back in print, and it’s worth adding to your survival library, if only for the traps. This bait-driven spring pole snare is my go-to trap for most small game animals and most occasions. To build this trap, you’ll need to find a strong, flexible sapling to serve as a spring pole, a forked stake to drive into the ground, a pencil-diameter toggle stick, a snare line, a toggle line, a bait stick, and some bait.
