could not see the vein or form any definite opinion of its capacity or 
character. The out-crop, however, covers several acres of ground. 
This discovery of Corundum is not without its value to the arts. In- 
deed, as an abrasive it has no superior except the Diamond, and its de- 
velopement and general introduction as an abrasive will enlarge the de- 
mand for it. Along the zone of these Chrysolite dikes, it will, I have no 
doubt he developed in large quantity as the demand for it increases. 
Besides this general use for it in the arts, I have reason for believing that 
gems of Sapphire and Buby of great value will yet be found. 
Chromite, or chromate of Iron occurs in the Chrysolite rocks through- 
out the entire range so far as I have examined it. I have never been 
upon an out-crop of this rock which did not contain crystals of Chromite 
imbedded in the rock. At a few localities it has been observed in con- 
siderable masses. On the mine fork of Jack’s creek in Yancey county, 
Chrome ore crops out on a Chrysolite ridge, where from the angular 
character of the blocks there are good reason to suspect that a vein exists. 
I have obtained specimens at that locality quite free from foreign matter 
and rich in Chromium. Near the town of Webster, in Jackson county, 
there also exists Chromite. Many years ago when I first examined the 
locality, there were masses upon the surface of from one to two hundred 
pounds weight. It was destroyed for concealment, or used in building a 
road by the county authorities, so that very little can now be seen upon 
the surface. During my last examination, however, I found a vein of it 
exposed in a gulley. This vein is enclosed by Chrysolite. From what 
I know of the large angular blocks that once lay upon the surface and the 
character of the small vein I have recently seen, I think that a valuable 
deposit of this ore exists here. At Col. Jenk’s Corundum mine in Ma- 
con county, I obtained several masses of Chromite of eight or ten pounds 
weight previous to the purchase of the property by Col. J. At several 
other points I have often found small lumps of it from the size of a pea 
to that of a hen’s egg. No special search, however, has been made for 
it, owing to the remoteness of the localities from railroad transportation. 
There is one other rare mineral that occurs with the Chrysolite at Web- 
ster. I allude to Genthite. This mineral contains a large per cent, of 
Nickle. It has the appearance of a hydrous silicate, and occurs in seams 
of serpentine, sometimes a quarter of an inch thick. It also occurs in a 
very porous Chalcedony. The contrast between the green Genthite and 
the white Chalcedony makes a rock of rare beauty. There are also spec- 
imens of Bronzite at this locality. 
There are numerous granite dikes all along the range of Chrysolite 
dikes, the granite dikes, however, taking a wider range than the Chryso-
