An unidentified man sets in a chair hoisted by a large chain down a 35-foot man-made shaft from the top of Chain Mill Falls to the overhang below. The mill was operated by buckets attached to chains that captured water from the falls; the chains were attached to a large wooden wheel, like a cog, and the momentum of the water filling the buckets powered the wheel, which turned the millstones used to grind corn and wheat into flour. According to historian Frank Bird, the mill was built around 1815 by a man named William Gordon, who designed the chain-and-bucket method to harness energy from the falling water. The falls is located about two miles from Hanover near State Route 56. V000608 View of the J.C. Hill Grocery store in Hanover.
