An 1802 extract of a memoir by Citizen Brulley, read at the Lyceum of Arts, on growing the indigo plant and making indigo. It describes the species of indigo plant and the French colonial practice of mixing indigo-franc and wild indigo seed. It then gives the vat process for extracting the dye: maceration, the test for when it is complete, beating in a second vat, and draining and drying the paste. It credits a St. Domingo planter, Nazon, with a method meant to prevent failed vats.
