Louisiana Revised Statutes Tit. 41, § 92. Contracts; reservation of mineral rights

The grants shall be evidenced by contracts and may be upon such terms and conditions as the register of the state land office may deem to be to the best interest of the state, and shall be subject to approval of the governor. The contracts shall provide that default on the part of the grantee in the performance of any term or condition thereof shall operate ipso facto and without a putting in default by the state, as a cancellation of the grant. All mineral rights on any lands granted under this Chapter shall be reserved to the state.
