All bonds which have been duly sold and delivered constitute valid and legally binding general obligations of the State of California, and the full faith and credit of the State of California is pledged for the punctual payment of both principal and interest. There shall be collected annually in the same manner, and at the same time as other state revenue is collected, the sum, in addition to the ordinary revenues of the state, required to pay the principal and interest on the bonds. It is the duty of all officers charged by law with any duty in regard to the collection of that revenue to perform each and every act which is necessary to collect this additional sum. All money deposited in the fund which has been derived from premium and accrued interest on bonds sold is available for transfer to the General Fund as a credit to expenditures for bond interest.
