The board of county commissioners shall keep a book in which all orders and decisions made by it shall be recorded. Such book shall be known as "a record of the proceedings of the board of county commissioners". All orders and vouchers for the allowance and payment of moneys from the county treasury shall state on what account and to whom the allowance is made. The same shall be dated and numbered with the number of the warrant issued in payment thereof. Approval of orders and vouchers shall be recorded in the record of the proceedings and this shall be sufficient to indicate approval without requiring a majority of the board to sign or initial the orders and vouchers.
