The bonds issued under the provisions of this chapter may not be an indebtedness of the state of North Dakota nor of the institution for which they are issued nor of the state board of higher education thereof, nor of the individual members, officers or agents thereof nor may any building or other campus improvement or the land upon which it is situated, or any part thereof be security for or be levied upon or sold for the payment of said bonds, but the said bonds must be special obligations payable solely from the revenues to be derived from the operation of the building or other campus improvement, and the board is authorized and directed to pledge all or any part of such revenues to the payment of principal and interest on the bonds. In order to secure the prompt payment of such principal and interest and the proper application of the revenues pledged thereto, the board is authorized by appropriate provisions in the resolution or resolutions authorizing the bonds:
