North Oaks, United States of America
North Oaks Farm, also known as Hill Farm, is an open-air museum in North Oaks, Minnesota, United States, preserving buildings of a 3,300-acre (1,300 ha) demonstration farm established by railroad magnate James J. Hill in 1883. Elements of the farm were listed on the National Register of Historic Pla
ces as James J. Hill's North Oaks Farm, Dairy Building in 1999. In the Dairy Building, Hill had installed a DeLaval separator and barrel churns, which automated the production of butter, using centrifugal force powered by a steam engine. The operation was a forerunner of the modern commercial butter-making industry. At the Blacksmith and Machine Shop horses were shod and hinges and wagon wheels were constructed for use on the farm.
