Loans and discounts are handled by an officer in small banks, but in larger institutions a separate department has charge of the records and the mechanical details of the work. The discount teller gives the borrower credit for the amount of approved loans by using cashier's checks for out-of-town borrowers and ordinary credit slips for his own depositors. In a sense, then, he is a receiving teller of a special form. The actual loaning of the bank's money is always done by an officer of the institution, regardless of its size or kind.
