Graphite ("black lead") was mined here by the Nipmuc to make ceremonial paints. John Winthrop the Younger (1606-1676) purchased the mine in 1644. Actual work did not begin until April 1658, and the mine seems to have been soon abandoned. Another John Winthrop, nephew of the original owner, started mining again in 1738 but ceased operations after a couple of years. There is no record of mining again until 1828-29 when Frederick Tudor (1783-1864) of Boston reopened the mine and operated it until his death in 1864. Purchased by the Massachusetts Graphite Company in 1902, it was operated occasionally until at least 1911.
