I encountered a sentence "It smelt of boiled cabbage and old rag mats." while I was reading a book.
Searching the Internet, I have discovered that in general, "to smell of" and "to smell with" are both OK. Could you, please, explain me the difference, if any, between them? Can we use them both interchangeably?
P.S. Until now I have been using only "to smell with". For example "It smells with watermelon."
