APPENDIX. 
Gneiss, which encloses these Chrysolite and Serpentine beds, is somewhat 
peculiar and deserves a more special description. It bears evidence of 
having been much affected by heat from the dike fissures which traverse 
it. It is consequently hard and crystalline in a high degree. This rock 
is charged with grains and partial crystals of a rose color, sometimes 
sparcely distributed, and at others predominating. I have heretofore 
classified this rose colored material as a species of Garnet, and see no good 
reason for changing my opinion. The Mica in the composition of this 
rock is usually of a brownish black color, 'while the Feldspar is quite white. 
This contrast in color, of the component minerals, gives to well selected 
specimens a very handsome appearance. 
The mineral silicates found in this rock are almost entirely anhydrous 
silicates of Alumina, such as Kyauite, Tourmaline, Garnet, Epidote, etc. 
It is also charged with metalic sulphurets of Iron and Copper, and very 
sparsely with sulphurets of Lead and Zinc. It is in this zone that the cop- 
per mines of Jackson county are located. 
Along this belt there are numerous out-crops and beds of Syenite. In 
this distribution of the Hornblend there is a fact worthy of special note, 
because it has a special bearing upon the question under consideration. 
In traversing the Chrysolite out-crops from Corundum Hill, in Macon 
county, north-eastwards, the Geologist cannot fail to observe a gradual 
decrease in the approximate out-crops of Hornblend to the Chrysolite, and 
an increase of Feldspar, usually decomposed, forming a species of Kaolin. 
This is especially true up to the Yancey county line. From Corundum 
Hill, as the zone crosses the Tennessee valley in a south-west direction, 
the fissures scatter, until instead of being from one to two miles across the 
zone, it is some eight miles across it in the Tennessee valley. Some 
observations upon the facts here stated led me to suspect some important 
change in the axis of the disturbing force, and after such examinations as 
I have been able to make, I am satisfied that the axis of disturbance, 
which had maintained a uniform line from Mitchell county to this point, 
here terminated against the most southern and massive part of the Han- 
teeyalee mountain. This is a transverse chain that intersects the Blue 
Bidge at the head of the Tennessee river, Hanteeyalee river and Talula. 
Here the Blue Ridge curves around the head of Tennessee river and runs 
several miles north, until it forms a junction with the Nanteeyalee, and 
then tends off again to the south-west. Had the line of disturbance con- 
tinued in its regular course, it would have passed directly through this 
great mass at the point of intersection between the Blue Ridge and the 
Nanteeyalee, and from that point south-westward, the dikes and out-crops 
would have traversed the main crest of the ridge. The axis of disturb-
