If the amount in the sinking fund is insufficient to pay the interest on, and principal of, such bonds as they become due, then the deficiency shall be paid by the State Treasurer from any funds in the State Treasury not otherwise appropriated. All such bonds shall contain recitals on their faces substantially covering the provisions of this section.
