Painter Mine.—The Painter mine is 2V2 miles S. 65° E. of Sylva, on thenorthwest slope of a small mountain. The mine was opened many yearsago by two shafts, with drifts, and a tunnel at a lower level but not connect-ing with the shafts. Later, more systematic operations resulted in a tunnel175 feet long opening into a stope nearly 200 feet long. The stope was car-ried to a depth of 40 feet below the tunnel level and some 20 feet above, be-ing very irregular in shape. A longitudinal section through the vein show-ing the shape of the workings is given in figure 7. The country rock is. Figure 7—Section in piano of the vein at the Painter mine. Jackson County, N. C. garnetiferous mica gneiss which has a strike of N. 35° W. and a high dipto the southwest. The pegmatite is approximately conformable with the in-closing gneiss. The vein varies from 2 to more than 15 feet in thicknessat the end of the stope. A large quartz streak in the middle of the pegma-tite in this stope is left as a foot wall for the workings. The mica streaklies between this and the hanging wall. It is possible that more mica mightbe found by further prospecting the feldspar streak between the quartzstreak and the foot wall. Several large blocks of mica were exposed in theface of the stope at the time of examination (1905). The mica is mostlyclear and of good quality, though a small amount of specked material wasseen on the dumps. A strip of ruled mica of fine clear rum color savedas a specimen at the mine measured 2 by 15 inches. It exhibited the Astructure slightly at each en
