 Two additional sawmills were built in the 1870s, one at the original settlement, called Fayville, and one at the new settlement at the railroad terminus, which became known as South Glastenbury.Dozens of kilns were built at South Glastenbury for converting the lumber to charcoal; at this time Glastenbury was one of the three foremost sites in Vermont for producing the charcoal which was feeding iron production in nearby Shaftsbury and in Troy, New York.By the late 1880s, however, the mountain had been cleared of nearly all of its mature trees, and the town's economy dipped dramatically.
