Cumberland County was the site of an important saltpeter mine. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from Grassy Cove Saltpeter Cave. According to Barr (1961), Dicky Mathews began the manufacture of gunpowder at the cave in 1859. His son was killed by an explosion at Powder House Spring below the cave. This is an exceptionally large cave and evidence of mining extends far from the entrance. The leaching vats were located in a large room near the entrance, but this room is damp and the wooden vats have deteriorated to the point that they are difficult to recognize. It is also possible that this cave may have been mined much earlier, during the War of 1812. (Thomas C. Barr, Jr., "Caves of Tennessee", Bulletin 64 of the Tennessee Division of Geology, 1961, 568 pages.)
