1.—Quartz rock of the King’s Mountain range. 2.—Red iron ore, to some extent specular, and extending from Gel- 
key’s Mountain to North Carolina—explored at all the iron-works. 3.—Gold ore associated with iron ore.

On the North Carolina side a very valuable gold mine occurs very near King’s Mountain, and 
the precious metal may be traced through York, as at Carroll’s mine and other localities; in Spar- 
tanburg, at Lockhart’s and other mines, not far from the itacolumite locality, and thence into Union, 
to the Fair Forest mines. In Pickens gold is also found in the branch where this rock occurs. 
The resemblance between this group and the Brazilian rocks described by Humboldt, is suffi- 
ciently striking to invest them with a considerable degree of interest.* 
In Pickens District rutile is abundant, but as yet neither platinum nor diamonds have been found 
in this State, although thousands of the latter may have escaped with the refuse gravel at the gold 
mines, as hitherto no attention has been paid to the subject. 
In the transactions of the Geological Society of Pennsylvania I find the following notice. 
“ We have just had an opportunity of examining a fine diamond, weighing one carat and a half, 
recently found in the washings of a stream, in Carolina. It is in the possession of Mr. T. G. 
Clemson, whose intention it is to favor the society with a more particular account of this discovery. 
Sept. 10th, 1835.” 
In 1836 I saw, in the possession of Mr. Simms, a diamond found in the Portis mine, near the 
corner of Nash, Franklin, and Warren Counties, North Carolina. Prof. Shepard has described, in 
the American Journal of Science and Arts,t and figured a diamond found in Twitty’s gold mine, 
Rutherford County, North Carolina; and in a paper read before the Association of Geologists and 
Naturalists, he mentions two diamonds found in a deposit mine, in Hall County, Georgia, one of 
which is said to be in the possession of Dr. Daniel, of Savannah. 
At the latter locality, and in Habersham and Rabun Counties, Mr. Schrieber found flexible quartz. 
In North Carolina it has been found by Drs. Hardy and Irwin, and in Lincoln by Prof. Olmstead. 
The localities in Burke, N. C. Pickens, 8. C. and Rabun, Habersham, and Hall, Ga. belong to 
the same range, and the localities in Lincoln, (N. C.) and Spartanburg, (S. C.) to another. 
Speaking of the specimens collected in Rabun, Habersham and Hall Counties, Georgia, by Mr. 
Schreiber, Prof. Shepard says “several of the specimens collected by him possessed a decidedly 
secondary aspect; and Prof. S. inferred from the account given him by Mr. S. that in some of the 
localities its primary character was less certain than at others.” 'This is the first time that I have
