No, I don’t remember that one. My first trapping book fifty-plus years ago was titled Pennsylvania Trapping and Predator Control Methods by Paul L.Tailor.
I still have my original copy plus one I bought decades later to keep at Camp. It’s interesting to look how things were done and how things have changed since the early 70s.
Tell us what has changed
There is a chapter dedicated to calling/hunting great horned owls which includes methods such as using crows to locate them then stalking and picking them off with a scoped rifle. Also on "driving" them similar to a deer drive. Great horned owls are protected today by both state and federal laws.
The preference for stretcher board sizes seems to have turned towards narrower boards. The red fox boards specs in the book call for a bottom width of 9" on a 48" long stretcher. NAFA specs 7" at 66" long for a large fox board and FHA specs 5.25" at 60" long. Coon board specs in the book are 2" wider than NAFA specs and 3" wider than FHA specs for the same length (48"). Maybe NAFA and FHA specs were always narrow like that, I don't know.
The sets described using exposed bait are illegal in PA today. The bulk set in particular was one i used to use quite a bit. You set three or four traps on drags around a pile of bait like a dead deer, deer guts or chicken butchering remains.
Those are a few of the changes.
