Its small size suggests a general-purpose barn rather than a large specialized dairy barn. It shows how promoters tried to adapt the round form to small-scale farms.","narrative":"Near Whitehall in Greene County, Illinois, a round barn built in 1912 for farmer Harry C. Price survives in excellent condition. Its diameter is 36 feet 6 inches, making it small compared with the 60-foot median for Illinois round barns, though not the smallest, since a Clay County barn measures 30 feet. Brown vitrified tile blocks enclose the ground level and loft, and a single-hip roof of wooden shingles carries a cupola rising 25 feet above grade. Double wooden doors open onto a central drive on the north, with a matching opening on the south whose doors have been removed. Hay entered the loft through a north dormer, and feed went down to troughs in semicircles beside the drive. The barn is valued as a departure from the typical Illinois round barn. Its modest scale suggests general farm use rather than specialized dairying, and it shows how the round form was adapted to small farms. A descendant reported that it proved inefficient.","period_of_significance":null,"architect_builder":"unknown (built for farmer Harry C.
