79. Enclase, 
General Clingman mentions a very handsome crystal of this rare min- 
eral trotn the gold mine of the late Morril Mills, in the eastern part of 
Polk county. 
SO. Titan ite. 
General Clingman mentions titanite, or sphene, as occurring in Bun- 
combe county. I have observed it at Morganton Springs* in minute 
brown crystals, in hornblende slate and in granite at White’s Mills,* in 
Gaston county, and at Rogers’ Ore Bank, near Danbury, in Stokes county. 
To this species probably belong two of Prof. Shepard’s very doubtful 
species, the Xanthitane, from Green river, in Henderson county, and the 
Pyromelane , from the gold washings of McDowell county. 
81. Staurolite. 
Very large, brownish red crystals, from two and a half to three inches 
in length, and one to one and a half inches wide, single individuals as 
well as twins, at the Parker Mine,* in Cherokee county. There are 
many other localities in Cherokee and Macon counties, where it occurs 
abundantly in argillaceous and talcose slates. 
B. Hydrous Silicates. 
S2. Chkysocolla. 
Inferior specimens, generally much mixed with other copper ores, have 
been observed at the copper mines, for instance, at the Gardner Hill and 
Cambridge Mines, in Guilford county, the Pioneer Mills, in Cabarrus 
county, the Hopewell,* in Mecklenburg county, the Clegg’s* Mine, in 
Chatham county, the Gap Creek Mine,* in Watauga, and many others. 
S3. Calamine. 
The only specimen of calamine, which I have observed, came from 
Silver Hill, Davidson county, where it occurs sparingly as ai incrustation 
•of fibrous and radiating structure upon argentiferous galenite.
