He represented the Sugar Planters Association in seeking a tariff against foreign competition, which they gained from Congress. Louisiana planters could not compete against outside sugar. In 1884, Warmoth traveled to France and Germany to study their sugar industries, and he developed an experimental station at his plantation afterward. Unable to compete with foreign sugar, Warmoth sold his plantation and moved with his wife and family to New Orleans."Warmoth, Henry Clay", Library, University of North Carolina
