Jerome K Jerome the author of Three Men in a Boat and Three Men on the Bummell.
Regarding Bummell. I haven't read the book, but I have a feeling that to be "on the bummell" meant tramping about with no particular aim in view - rather like going walk-about. Can anyone confirm this or am I way off beam? If it is so was this the origin of the American usage of the word "bum"?
