RENTE FONCIERE. This is a technical phrase used in Louisiana. It is a rent
which issues out of land, and it is of its essence that it be perpetual, for
if it be made but for a limited time, it is a lease. It may, however, be
extinguished. Civ. Code of Lo. art. 2750, 2759; Poth. h.t. Vide Ground-rent.
