of this paper is to record the results of field and laboratory (chemical and 

 microscopical) studies of an interesting area that has long been known to 

 the mineralogist but practically neglected by the geologist. The chemical 

 analyses of the specimens collected are the work of the junior author.

County; six miles southwest of Lincolnton; and about forty miles north- 

 west of Augusta (map, fig. 1). It is within but near the eastern border of 

 the Piedmont Plateau province, a short distance north of the fall line, which 

 marks the jsassage of the plateau crystalline rocks beneath the Coastal 

 Plain sediments. The area forms a part of the central divide region be- 

 tween the tributaries of Little River on the south and southeast and those 

 of the Savannah River on the east and north. Little River is distant about 

 eight miles south of the mountain and is the nearest stream of large size.
