Morrison Waite,
West St. Louis Savings Bank v. Shawnee County Bank…
“ Ordinarily, the cashier, being the ostensible executive officer of a bank, is presumed to have, in the absence of positive restrictions, all the power necessary for such an officer in the transaction of the legitimate business of banking. Thus, he is generally understood to have authority to indorse the commercial paper of his bank and bind the bank by the indorsement. ”
