Established roughly ten leagues (about 28 miles) down river from New Orleans, on site later forming part of Plaquemines Parish. Identifies main house, outbuildings, slave quarters, cultivated fields, and garden; keyed to 8 references. From Dumont's 1747 manuscript memoir of his experiences in Louisiana between 1715-1737.
