Maybe I have. Could be. Yep, sure could be.

And a "blue-butted schoolmarm" is a logging term (perhaps only in the North of Wisconsin and Michigan?) for a log with a crotch in it, the trimmed branch of which can catch a guy as it moves down the belt or chain and carry him into the saw. Think of a Y-shaped log.

By the way, Amos: a while back I tried to buy a hand-held star drill. I finally gave up. If you know where I can get one please let me know.
