..... and before there were flushing loos,
(are you sure you wanted to know this

)
someone had to go around all the posh houses and collect the "night soil" and take it away !

Fortunately, it's died out as an occupation
PS:
My Dad tells me his Grandfather was the WC-Janitor at Regents Park;
In the 1901 census it states "Parkkeeper". (Well, it sounds nicer on the census form ! )
