Lands belonging to or under the control of the state shall never be donated, directly or indirectly, to private corporations, associations, or individuals, or railroad companies; nor shall such lands be sold to corporations or associations for a less price than that for which they are subject to sale to individuals; provided, that nothing contained in this section shall prevent the legislature from granting a right of way, not exceeding one hundred and twenty-five feet in width, as a mere easement, for railroads or telegraph or telephone lines across state land, and the legislature shall never dispose of the land covered by such right of way except subject to such easement.
