If the entire issue of bonds is to mature at one time, such bonds may be called for redemption in numerical order at par and accrued interest on any interest-payment date prior to their fixed maturity, and a statement to that effect shall be set forth in each bond. No bond shall be callable or redeemable prior to its fixed maturity date, unless a statement that the bond is callable is contained in the bond.
