At Cooper's Falls was formerly concentrated a little settlement and some business interests. The falls are about six feet high, and are about a mile below De Kalb Village. There Judge Cooper erected a saw mill and a grist mill in 1804-1805. Subsequently a stock company built a furnace there, the ore being obtained in the Town of Hermon. The mine was abandoned, the grist mill went to decay, and the water power now is not in use.
