ner of Georgia, and extending thence, in the direction of the

North Carolina. Beginning for example, in the northeastern 
corner of Jackson Co. (N. Car.), Mr. Smith sketches it, as run- 
ning in a southwesterly course across Macon Co., where it strikes 
the Georgia State line, its general direction coinciding with 
the trend of the Blue Ridge until it reaches the head of Tennes- 
whence it pursues its original course of N.E. and 8.W. across 
the Chunckygal mountains, where it again enters the Blue 
Ridge, and probably continues through several of the upper 
counties of Georgia, as Union, Habersham, Lumpkin and Hall. 
Thus far, the corundum is known to occur only in a single forma- 
tion, which may be designated as chrysolitic rock; though

fully appear farther on, it is not the true chrysolite, though 
containing this species to some extent, in an intermingled or dis- 
seminated condition.
