That is good to know! This fall and winter I'll definitely be out trying to find more small bottles like this. One good thing is they are able to escape damage easier.
I found this little guy in a shovel full of dirt when I was cleaning out the hole on a dig many years ago. It says "Cutter" on the side and that's that!. It's a towering 1 inch tall and .625 inches in diameter. I think I once say that it was a poison but not sure. If it was it must of really packed a punch!
