In page Hathersage:

"

In 1728 Daniel Defoe recorded how the moors around Hathersage were the source of building stones and millstones.[5] Millstones were used in wood-pulping industries in the area and were also exported to North America, Russia and Scandinavia for the same purpose. Locally the millstones were also used for crushing lead ore and the ingredients for paint. In Dorset Peak stones were used for farm meal and barley crushing. The local gritstone tended to discolour bread, so were not generally used to grind wheat.[6]
