Your grandmother told me that at that time Miss Rosa actually could not count money, change, that she knew the progression of the coins in theory but that apparently she had never had the actual cash to see, touch, experiment and prove with; that on certain days of the week she would go down town with a basket and shop at certain stores which Mr Coldfield had already designated, with no coin nor sum of money changing lip or hand, and that later in the day Mr Coldfield would trace her course by the debits scratched on paper or on walls and counters, and pay them.
