specimens. It is a noteworthy fact that wherever we find this rose 
colored garnet in the Gneiss, we invariably find sulphurets of Iron and 
Copper. This rock is evidently the source of the Copper of this belt, 
because the veins that have been developed are inclosed in it and Syenite, 
some of which also contains the same variety of Garnet. Following and 
in the center of this garnetic Gneiss there has been some igneous dis- 
turbances, doubtless at an early period after the Gneiss beds were up- 
heaved and turned upon their edges. There is a system of Chrysolite 
dikes in this particular zone extending from the north-east corner of 
Mitchell county to Track-rock, in Union county, Georgia, a distance of 
about hundred and ninety miles. It perhaps continues through Georgia 
into Alabama. Indeed, I explored a similar system of Chrysolite out- 
crops in Tallapoosa county, Alabama, holding the same relation to the 
axis of upheaved and the Taconic beds that they do here. These dikes 
occup}' a narrow zone throughout the entire length. The out-crops, 
however, while numerous, are at intervals, so that there is no continuous 
bed of Chrysolite or Serpentine. These Chrysolite dikes bear Corundum 
at various localities. During the hasty examination which I made of the 
localities in Mitchell I was unable to find Corundum. I was unable, also, 
to detect some of the more intimately associated minerals. Through 
Yancey my explorations had a similar result, with the exception that at 
one locality where, it was alleged, a handsome piece of blue Corundum 
had been picked up. There I obtained by panning the sands of the 
branch some very small fragments and crystals. The general absence of 
Tourmaline, Hornblend, Margarite, Chalcedony and Ripidolite led me to 
suspect that but little Corundum would be found on those out-crops I 
examined. 
Passing into Madison county, on the waters of Little Ivey, there exists 
Corundum on the lands of Win. Carter, about one mile from Democrat 
post-office. At this locality it is associated with Margarite, Tourmaline 
and Uipidolite. I gave instructions to the parties, who held a lease on 
the property, how to prosecute their search, and have since learned that 
they succeeded in finding a small vein. There are no out-crops of interest 
in Buncombe until we reach the valley of New Fouud creek, on the west 
side of the French Broad river. There, on the lands of Mrs. Luther, I 
found a small specimen of the mineral. My examination of other out- 
crops in the same neighborhood were unsuccessful. At the head of New 
Found creek the line of dike fissures enters Haywood county and passes 
down North Hominy creek two or three miles. On the lands of Mr. 
Enoch Hall I found Corundum in small fragments, having Ripidolite as 
the associated mineral. The out-crop at this locality iB small, covering
