but little white foliated Tale, such as occurs at the Culsagee mine and in 
its vicinity. This out-crop is comparatively barren in Chalcedony, 
although occasional pieces are met with. I have not yet found so much 
as a single specimen of Tourmaline at this locality. At every other point 
east of this, and at Gainesville, Ga., where I recently discovered Corun- 
dum, Tourmaline is present. Its absence here is a distinguishing 
feature between the Buck creek and Culsagee localities. Nor does An- 
thophyllite abound here as it does at Corundum Hill. There it exists as 
large massive rocks ; here I have not found even a good hand specimen. 
Another characteristic of this out-crop is the sparcity of Chromium, 
There is not an appreciable amount of Chrome sand present to interfere 
with the process of washing Corundum from the dirt. There is much 
more Actinolite here than at the Culsagee locality, and Tremolite is some- 
what abundant with Actinolite. Amianthus also occurs here of a very 
fine quality, and Picrolite exists in seams or apparent veins in the Chryso- 
lite rocks. Beautiful specimens of it may be had at this point. I have 
here found Chrysolite attached as an enveloping matter to considerable 
masses of Corundum ; and I also found a white silky fibrous mineral, 
which I have classified as Marmolite. This also envelopes Corundum. 
The most marked characteristic of the Buck creek out-crop is the oc- 
currence of Feldspars differing from those heretofore found in the general 
geology of this section. I have not found anything like them at any 
other point in "Western Carolina. One variety is found in masses upon the 
surface resembling in shape the masses of Corundum found in close 
proximity to the Feldspar. Some of these lumps will weigh from eighty 
to a hundred pounds. Some of them when broken are very white and 
are massive in their structure, having very seldom any of the usual 
facel angles of common Feldspar. I have a specimen in which it seems 
to run imperceptably into Corundum. This may prove to be a pseudo- 
morph, a question I am anxious to have examined by the most profound 
anylitical chemistry. These Feldspathic masses differ from Corundum in 
specific gravity, hardness and the usual crystalline faces. Some of this 
variety more translucent than that just described and having the faces, 
luster and hardness of Feldspar is penetrated through and through with 
crystals of black Hornblend. This is probably Orthoclase. 
On another part of the out-crop there occurs large masses of appa- 
rently another variety of Feldspar. Seams running through some of these 
masses are filled with a rather granular Actinolite of a most beautiful 
green color. Grains of this Actinolite sometimes penetrate the Feldspar, 
which often has a greenish and blueish green color. In this variety, 
there occurs, sometimes amongst the Actinolite, and then again in the
