- One audio cassette. Duvall, who owned Percheron horse (improted from France), was trained by Amish farmers in Ohio (who also use Percheron horses) on traditional horse training and farmwork techniques. In the interview, Duvall discusses the horses (traits, uses of, and qualities), harnessing techniques, training, driving, and wagons. The interview was created as fieldwork for the 1993 Rural Folklfie Days, in which Duvall participated as a demonstrator.
