A wheel or circular mass of rock used in grinding wheat and other grains. For good millstones the rock must be tough, hard, and possess a cellular structure so as to maintain a rough grinding stirface. Several varieties of rocks have been found to possess these qualities in a greater or less degree, and have been extensively employed for millstones. In the United States the rock most commonly used is a coarse granular sandstone, which is obtained in Ulster County, N. V., in Lancaster County, Pa., and in .Montgomery County. Va. The celebrated French l)uhrstones consist of a cellular chert occurring in the Tertiary of the Paris basin. The German millstones are largely quarried from a sheet of basaltic lava found near Cologne. The foreign stone is imported into the United States in small pieces and is then built up into wheels, while the domestic stone is quarried and dressed to form a solid wheel. The introduction of the loller process for the manti- facture of Hour has ctirtailed the use of mill- stones to a great extent. In 1901 the production of millstones in the United States was valued at $57,179. See Abrasives. MILLSTONE GRIT. A hard siliceous con- glomerate with quartz pebbles.
