any other bonds of the District, and the proceeds thereform shall be

of the full faith and credit of the County Commissioners of Prince
George's County to the payment of the maturing principal of and
interest on said bonds and notes and, to the extent that the taxes
above provided for in this Section and any other moneys available
or to become available therefor (either through the issuance of bonds
or notes authorized hereunder or otherwise) are inadequate to pro-
vide the funds necessary to pay such principal and interest in any
year, said County Commissioners shall levy upon all property subject
to taxation within Prince George's County ad valo
