London Paper - Fluorite and Barite in Tennessee

My thanks are due to Mr. Frank Firmstone, Easton, Pa., who has called my attention to the statement in my paper' that " Barite, fluorite and quartz, thougll not observed in the Tennessee area," ... as possibly misleading to the reader, if construed to mean that such a discovery had never been made. Mr. Firmstone is correct in assuming that this statement referred only to the study of the worked areas of the metallic ores, especially zinc, made in the course of the survey upon which my paper was based. The occurrence of barite and fluorite with lead-ores in Tennessee was reported by Prof. Safford? in 1869, and by Safford and Killebrew? in 1887, with the further statement that about 1,000,000 lb. of barite were annually mined in Greene, Washington and Jefferson counties, Tenn., and that considerable deposits occur also in McMinn, Smith and other counties. It is also noted that the barite " usually occurs in veins, associated with galena." The present worked areas of barite are, however, distinct barite propositions, without workable quantities of either lead or zinc, so far as mining operations have gone, and the areas are more or less removed from the present areas of zinc-ores. Mr. Firmstone informs me also that, in 1892, he observed, in the magnesian limestone at Watauga Point, in Carter county, on the left bank of the Watauga river, a little below the mouth of Buffalo creek, small quantities of galena and some fluorite.
