Excerpt from The Adirondack Graphite Deposits
The world's chief supply of high-grade graphite comes from the island of Ceylon where it has been mined for nearly a century in a most primitive way but at low cost. In 1916 a little more than 70 per cent of the crude crystalline graphite used in this country came from Ceylon. Graphite is also mined extensively in Bohemia, Bavaria and Mexico, the last-named country being noted for the amorphous grade applicable to pencil manufacture. Madagascar has lately come into prominence as a source of the crystalline article and promises to vie with Ceylon in the quantity of exports, which already amounts to over one-half the total credited to that island.
