I still have a copy of Bushcraft. My sister gave the original copy that I had back to the library "for" me. The nerve of some people. I found it online a while back. It has some really good snare triggers and sets in it. I remember setting up a snare with two small trees, two loops, one trigger in a trail in the woods across the street from our house (small town America). I imagined checking it after school the next day thinking there would be a rabbit or maybe a coyote! held between the two trees, still alive, waiting to be set free. As the Aussies say, Yeahnah... There was a gory mess of two halves of a cat. It had ripped it in half and slung the innards all over the place. I still remember how bad that felt. No neighbors were missing cats and it was a very small town so at least there was that. Most likely it was a feral. No collar. I used a bit too much tree power I guess. I didn't repeat that snare.
