I live in a house built in 1804. I know there’s an old privy hole somewhere in our yard - probably under the apple tree. Might be some nice old bottles and other stuff down in there somewhere!
There ya go.
One of my colleagues (now deceased) used to claim the privy for his "square" when we were on a historic-site dig. He said that was where "all the good stuff" was.
Funny thing: he always wound up smelling like "the other stuff"...
We always put him downwind at lunch time... '-)
