Missouri Revised Statutes Title XI. Education and Libraries § 172.650. Certificates to remain unconvertible--renewal certificates issued, when

1. All of the state certificates of indebtedness issued to, and part of, the seminary fund, whether original certificates or renewals thereof, are hereby confirmed as sacred obligations of the state to said fund, and they shall be and remain nonnegotiable, unconvertible and untransferable from the purposes of their issue, and they shall remain so much of the permanent seminary fund as is represented by their amounts, respectively, until they shall be liquidated by the general assembly by appropriation and payment of the face amounts thereof to the seminary fund.

2. The general assembly may provide for the partial liquidation of any and all of said certificates by appropriation and payment to the seminary fund of a portion or portions of the face amounts thereof and, in any such event, a new certificate of indebtedness shall issue for the balance of the face amount of such partially liquidated certificate which remains unpaid after such partial liquidation.

3. When the certificates of indebtedness of the state to the seminary fund shall mature, renewal certificates in form substantially similar to the maturing certificates and for like amounts, payable to the state treasurer as trustee of the seminary fund, with like maturities, and bearing the same rates of interest, payable in like manner, as provided in the maturing certificates, shall be executed, countersigned, and sealed in like manner as specified in section 172.611.

4. Upon the execution of such renewal certificates, they shall be deposited with the state treasurer as part of the seminary fund and the matured certificates of indebtedness shall be forthwith cancelled by the state treasurer. Receipts for all original and renewal certificates of indebtedness deposited in the state treasury, and notices of all cancellations thereof, shall be given by the state treasurer to the board of curators of the state university.
