the latter in almost every copper mine in the State. The Guilford, Ca- 
barrus and Mecklenburg county copper mines contain it. I have observed 
the fibrous variety at Silver Hill and Conrad Ilill, in Davidson county,, 
the Gillis Mine,* in Person county, the Cheek Mine, in Moore county,, 
and both the fibrous and earthy malachite at Clegg’s Mine,* in Chatham 
county. It has been found in the Brushy Mountains,* Alexander county,, 
the Peach Bottom Mine,* Alleghany county, the Ore Knob Mine, in Ashe 
county, the Gap Creek Mine* in Watauga county, the Cullowhee,* Sa- 
vannah,* and Wary hut* Mines, in Jackson county, and many other 
localities too numerous to be mentioned. Pseudomorphs of malachite, 
» after cubical cuprite have been found at Cullen’s Mine, Cabarrus county. 
13b. Azurite. 
This variety of carbonate of copper is far less frequently met with. 
Small but very beautiful and perfect cryrtals are found at Clegg’s Mine,* 
in Chatham county, and at the Cheek Mine, in Moore county. It is rare 
at the Cullen and Bqger Mine, in Cabarrus county, and the Wilson Mine, 
In Mecklenburg county. 
137. Bismutite. 
In yellowish white concretions, often of a pearly lustre or white incrus- 
tations upon gold-bearing quartz, at the Asbnry Mine, in Gaston county, 
'where it has been discovered by Dr. Asbnry. 
Mineral Coal . 
138. Anthracite. 
A very interesting occurrence of anthracite is that of masses with con- 
ehoidal fracture in the vein rock at the Clegg Mine*. The bituminous 
coal, both ot the Deep and Dan rivers, is frequently, especially near trap- 
dykes, almost deprived ot its hydrocarbons, approaching often true 
•anthracite. 
139. Bituminous Coal. 
The greater portion of the coal in the Deep river beds is bituminous' 
coal, the volatile matter varying from about eight to thirty-two per cent. 
The Dan river coal, which I had an opportunity to examine, is so-called
