green crystalline masses, sometimes with indistinct crystals, have been 
found near White’s Mill,* Gaston county, and near Franklin, Macon 
county. Epidote of olive green or greyish and brownish green color 
occurs massive as a frequent admixture of hornblende slate, or diorite, 
sometimes forming pure masses of epidosite. It has been met with in 
many ot the magnetic iron ore beds. 
68. Zoisite (?) 
About half a mile southwest of Silver Hill. About twenty-one years 
ago a greyish white toliated and columnar mineral was found, when 
searching for the continuation of the vein, which had the appearance of 
zoisite. No further examination was made, and there is now probably 
no specimen preserved. 
69. P 1 1 log o pit e . 
Small brownish scales of it have been found in the granular limestone 
of Bolejack’s quarry,* near Germanton, and at Martin’s quary* on Snow 
creek, Stokes county, on Walnut creek,* one mile from the French Broad 
river, on Valley river, in Cherokee county, and, at Judge Pearson’s,* near 
the Yadkin river. 
70. Biotite. 
Biotite is a constituent of many of the granites, gneisses and mica- 
schists of North Carolina. It is found only in small black or brownish 
black plates or scales. The localities are too numerous for mentioning 
any particular one, as no fine specimens have as yet been observed. 
71. Muscovite. 
The mica of the gneiss and micaschist is mostly muscovite, hence it is 
one of the commonest minerals of North Carolina. In a few localities it 
is found in beautiful crystals, for instance, with magnetite, at Buekhorn,* 
in Chatham county, with quartz, at Hickory,* Catawba county, and with 
pyrite, in Stokes county. Since the year 1S67, it has been mined in 
many places and has been obtained in large plates, at times over three 
feet in diameter, generally of a brownish color, or in crystalline masses 
or small crystals, associated with grey granular quartz, orthoclase, etc., in 
several localities in Mitchell,* Yancey*, Burke, Caldwell, Catawba, Lin- 
coln and Cleaveland counties.
