The Osgood graphite veins were discovered in 1848 and property owner Horatio Osgood leased them to Moses Carelton of Lancaster, Massachusetts. Two years later, Calelton sublet them to J. and J. Seabury, a New York mining company; Jacob Seabury also bought the Town Farm Mine in 1858. The Osgood, or J. Seabury Lead Mine, operated through the Civil War, closing in about 1865. It reportedly produced 30 tons of graphite in one unspecified three-month period, a heroic rate of production for those days. The mine probably employed 20 to 25 men, whose toil in hammer-and-steel drilling, gunpowder blasting, and hauling must have been formidable. Nehemiah Flint died when hit by as falling rick here in 1850. Big blocks of waste rocks on the dumps still show odd triangular-shaped drill holes, presumably the result of steam-powered drill bit chatter. Adapted from a 1995 Grapevine II article by John Gilbert
