Charles DeLano Hine,
Letters from an old railway official…
(1912)
“ In the first place, the same man handles the money and its written representations, the accounts. When we reach the stage of having both a teller and a bookkeeper, the one is a check on the other, because of a difference in point of view. I do not understand that a bank considers its bookkeepers more honest than its tellers or vice versa. The bookkeeper came along to check the teller, not because of such marked variations in humanity, but because of the volume of business. There was more than one man could do. ”
