There's another version of Rowsty Dowt called I Doubt, I Doubt, My Fire Is Out.


*"Rowsty Dowt" is probably nonsense. FYI According to the Oxford English Dictionary, "Rowsty" is the obsolete form of "rusty", and "dowt" is the obsolete form of "doubt".
**Shod was the past tense of "shed" and meant poured out or spilled, according to the Oxford English Dictionary. The Oxford Dictionary of Nursery Rhymes wrote, "'Shod' is the old past tense for shed, hence split: so the porridge appears to have been pease-porridge." I think the definition I found in the Oxford English Dictionary (i.e. poured out or spilled) is more straight-forward and makes more sense in this context.
***A truckler is a peddler according to The Annotated Mother Goose and The Oxford Dictionary of Nursery Rhymes. According to The Online Etymology Dictionary, the verb "to truck" meant "to exchange, barter".
