Mill Springs Park. The story of Mill Springs Mill began around 1817 when Charles, John and Dr. James Metcalf settled in the area and erected a cereal grinding mill, or a grist mill as they were usually called, for the milling of corn and wheat. The mill was equipped with 48 inch French burrs, millstones for grinding wheat and corn. Flour and cornmeal were custom ground for families who brought their grain by wagon or horseback on milling day.
