76. Tourmaline. 
The tourmalines:, found in many localities in North Carolina, are mostly 
the black varieties. Crystals of from one to two inches in size, have been 
found near Mountain Mine,* Cleaveland county, at Hanging Dog creek,* 
in Cherokee, in Rutherford county, Mecklenburg county. In slender 
black crystals, often radiating, and of needle-like shape, frequently flat- 
tened between the plates of muscovite; it is found at Ray's Mine,* near 
Burnsville, where also a greenish and yellowish green, fibrous and finely 
columnar variety occurs. It is frequently and in large masses associated 
with the corundum of Franklin, in Macon county. A large outcrop of 
fibrous and granular tourmaline, with quartz, is found about two hundred 
yards northeast of the Ellison Mine,* on the High Shoal property, in 
Gaston county, and a peculiar finely striated variety, with quartz, at Clubb 
Mountain ; similar finely fibrous wood-like masses occur at Leasburg,* 
Caswell county, and in Wake.* It has also been observed in the gold 
sands from Burke* county. Tourmaline rock and slate has been noticed 
at Kernersville,* Guilford county, at Bee Rock,* head of Turkey creek, 
in McDowell county, and at Jeanstown,* Rutherford county. 
77. Cyanitk. 
This is one of the characteristic accessories in many of the mica and 
hornblende schists of Macon,* Yancey,* Mitchell,* Caldwell,* Catawba,* 
Gaston* and other counties, and is generally of a greyish white or grey 
color, and in imperfect crystals. line crystals occur at Clubb Mountain ; 
coarsely bladed masses of a blue and greenish blue color at Swannanoa 
Gap,* also near Ray’s Mica Mine,* Yancey county ; in Wilkes* county, 
in Stokes county,* six miles east ot Danbury, at Davidson College,* in 
Mecklenburg county, at Crowder’s Mountain,* in Gaston county. A 
greyish white, radiating cyanite is found at Ararat river,* four miles south- 
east of Mount Airy, in Surry county, and a white cyanite at the foot of 
Barnett’s Mountain,* in Person county. 
7S. Topaz. 
Topaz is reported as occurring at. Crowder’s Mountain, but it is very 
doubtful ; crystals from there, which were considered topaz, were cyanite. 
The variety, pycnite, occurs in finely columnar aggregations of a yel- 
lowish and brownish yellow color, associated with garnets, near White’s 
Mill,* Gaston county.
