This is the site of the Albery Mill. When the sluice gates were opened, the water rushed down the sluice (race) behind you and turned the two giant turbines on your left. They in turn rotated the line shaft and steel pulley (one remains attached by a shaft to the turbine seen below). A driving belt ran from the pulley to the alternator which generated the electricity. All of this equipment was located inside the mill. 

When the Albery brothers saw the success of electric generators in nearby communities, they were quick to talk their father into helping establish the Falls Electric Company. Electric service to the farmers and smaller surrounding towns grew quickly. Hundreds of farmers in the Stillwater Valley enjoyed the service from this hydro-electric power long before others in the county. Eventually owned by the Dayton Power & Light Company, they would not provide rural electric services until 1936 but spent their time placing rural lines, and used their electric source from Dayton to furnish the Stillwater Valley.
