YENANT, Jean Barre de (vay-nong) (sometimes written SAINT-VENANT), French agriculturist, born in Niort in 1737; died there in February, 1810. He came in his youth to Santo Domingo, founded there a model farm, and was appointed president of the colonial board of agriculture and trade, which post he retained for about twenty years, contributing in many ways toward developing the resources of the colony. He founded at Cape Francais the Academy of the Philadelphes, which under his auspices published many valuable manuscripts concerning the early history, discovery, and natural history of the island, sent out several scientific expeditions, and greatly fostered national education. After his return to Europe in 1788, Venant wrote, at the solicitation of the Paris societe d'agriculture, memoirs on the culture of cotton, coffee, indigo, tobacco, and sugar-cane, and urged the introduction of such occupations in southern France. His works include "Des colonies modernes sons la zone torride, et particulierement de celle de Saint-Domingue" (Paris, 1802).
