Mississippi Constitution Art. 4, § 95

Lands belonging to, or under the control of the State, shall never be donated directly or indirectly, to private corporations or individuals, or to railroad companies. Nor shall such land be sold to corporations or associations for a less price than that for which it is subject to sale to individuals. This, however, shall not prevent the Legislature from granting a right of way, not exceeding one hundred feet in width, as a mere easement, to railroads across state land, and the Legislature shall never dispose of the land covered by said right of way so long as such easement exists.
