Most of the mines which yield well show signs of having been worked before, a very long time ago, no doubt by the occupants before the Indians. The mica is of excellent quality and easily mined. It is got out in large irregular-shaped blocks and transported to the factories, where it is carefully split by hand, and the laminae, of as large size as can be obtained, are trimmed with shears and tied up in packages for market. The quantity of refuse, broken, and rotten mica piled up about the factories is immense, and all the roads round about glisten with its scales. Garnets are often found imbedded in the laminae, flattened by the extreme pressure to which the mass was subjected. It is fascinating material, this mica, to handle, and we amused ourselves by experimenting on the thinness to which its scales could be reduced by splitting. It was at Bakersville that we saw specimens of mica that resembled the delicate tracery in the moss-agate and had the iridescent sheen of the rainbow colors--the most delicate greens, reds, blues, purples, and gold, changing from one to the other in the reflected light. In the texture were the tracings of fossil forms of ferns and the most exquisite and delicate vegetable beauty of the coal age. But the magnet shows this tracery to be iron.
