Beneath the land of the Davidsons and Baileys lay the largest and richest deposit of bituminous coal in the world. The first seam was discovered in nearby Pocahontas, Virginia in the backyard of Jordan Nelson. President Frederick Kimball of the Norfolk and Western Railway described this as the "most spectacular find on the continent and indeed perhaps of the entire planet." The coal seam had been mentioned much earlier in Thomas Jefferson's "Notes on the State of Virginia", but it was not mined until 1890.
