Country girl's reading (7)
I believe the answer is:
perusal
'reading' is the definition.
(perusal is a kind of reading)
'country girl's' is the wordplay.
'country' becomes 'peru' (Peru is an example).
'girl' becomes 'sal' (feminine given name**).
'peru'+'sal'='PERUSAL'
(Other definitions for perusal that I've seen before include "A casual read or study" , "Process of examination" , "Thorough reading" , "Careful look" , "thorough scan" .)
