An officer of a moneyed Institution, or commercial house, or bank, who is intrusted with, and whose duty it is to take care of, the cash or money of such institution or bank. The cashier of a bank is the executive officer, through whom the whole financial operations of the bank are conducted. He receives and pays out its moneys, collects and pays its debts, and receives and transfers its commercial securities. Tellers and other subordinate officers may be appointed, but they are under his direction, and are, as it were, the arms by which designated portions of his various functions are discharged. The directors may limit his authority as they deem proper, but this would not affect those to whom the limitation was unknown. Merchants’ Nat. Bank v. State Nat. Bank, 10 Wall. G50, 19 L. Ed. 100S.
