up a stump/calculate

[Barbara Need]

A fellow student asked me about the following. I was unable to help
him and offered to forward his message to the list.


Does anyone know if 'up a stump' as an idiom and 'I calculate' in the
sense of 'I suppose' are used in Appalachian speech?  The sources I
have found (DARE and the Dictionary of American Regionalisms) suggest
that both are chiefly Northern.  Additionally, the idiom usually
means 'to be pregnant'.  Can it have a more general meaning of simply
'to be in trouble'?

Thank you,
