The price of $40,000 was analyzed by Manigault as comprising $7500 for the mill, $70 per acre for the cleared, and $37 for the uncleared, and an average of $300 for the slaves.

The most detailed record of rice operations available is that made by Charles Manigault from the time of his purchase in 1833 of "Gowrie," on the Savannah River, twelve miles above the city of Savannah.
