Duluth Paper - An Aluminum-Ore

As far as known to the writer, no discovery has heretofore been made in the United States of deposits of beauxite, or the hydrated oxide of alumina. The deposit which forms the subject of this note was discovered in Floyd County, Georgia. Numerous "float" specimens, covering an area of about half an acre, indicate the location of the main deposit, which has thus far been opened to an inconsiderable extent only. The excavations show the beauxite to exist apparently as large masses in clay. The formation is Lower Silurian, as determined by the Geological Survey of Georgia. The surface in the immediate vicinity is covered with numerous angular fragments of chert, which is a characteristic rock throughout this formation in Georgia. An examination of the mineral shows it to have the oolitic structure common to several beauxites. It. varies in color from a light salmon to dark red, depending upon its contents of iron oxide. The light-colored specimens are comparatively soft, while the dark mineral is much harder, spots in the latter being
