Koskit & hästskit vid Tullgarnsnäs

Two days ago I put out some pictures from a sunday visit at Tullgarnsnäs. Walking on the fields there you can stumble on cowshit and horseshit. That made me think of an old favoruite phrase.

I am longing for a world where dung is dung and horseshit is horseshit.

I have always thought I red it in a book of Henry Miller - The Colossus on Maroussi in 1969. So I took the paperbackedition from the shelf and browsed the now brownish pages for a marking of that phrase. I have not found it. Hopefully someone can help me find the right source.
