Mineralogy of East Tennessee. 6s" 
plaster of Nova Scotia, and devoted by the farmers of that 
part of Virginia, and Tennessee, to similar purposes. 
Coal is said to exist in immense quantities in the Cumber- 
land Mountain. A bed of it is wrought near Knoxville; Ten- 
nessee. Itis of an excellent quality ; but wood is so abundant 
that it is used only in fo S. 
Sulphate of Barytes.—This mineral is found in Botetourt 
County, Virginia, near Fincastle ; and in Sevier County, Ten- 
nessee, : 
_ Hard Carbonates of Lime.—Stalactitical concretions abound 
in all the caves so often described as existing in this country. 
Those of Virginia are more perfectly crystallized than those 
of Tennessee, Under the head of hard carbonates should be 
mentioned an extensive bed or vein in Mo mery County, 
in the State of Virginia, near the seat of Colonel Hancock. 
It appears té have been found in a chasm, in the common 
limestone of the country, by a calcareous deposition which 
resembles, exactly, in all its characters, the calcareous con- 
cretions which are found forming in the caves of the country. 
The whole bed may, in fact, be regarded as a cave which has 
been filled up in the progress of time, by this curious pro- 
cess: Its width is various, from two feet to ten, or more, ex- 
tending along the side of a very steep ridge, for at least 50 
yards, and it is said to be continued seven miles farther. 
The siliceous carbonate of lime may be worth distinguishing 
from the common limestone. It is found in a bed near Colo- 
nel Hancock’s, and was supposed to be gypsum. It phospho- 
resces beautifully 5 it is white, and confusedly crystalline im 
its structure, and much harder than the common limestones 
Indeed, the limestone generally, on the east of the Alleghany; 
is somewhat harder than that on the west. 
-—There are several localities of this mineral. A miné 
of it is Wrought near New River, 15 miles from Wythe, Vir- 
ginia. Another locality of the ore of lead is said to have’ been 
discovered in Granger County, Tennessee, on land belonging 
to General Cocke. It exists also, very near the surface, on 
the plantation of the Rey. Mr. Craighead, near Nashville; 
Which, however, is out of our boundary.
