Pratt.] CORUNDUM IN GEORGIA. 63 
the garnet can be entirely eliminated this ore will not make a product 
thai can be used for making- the vitrified wheel. The vein lias an 
average width of nearly It feet, and will carry from 15 to 20 jjer cent 
of corundum. All these mines just referred to belong to the Toxaway 
Company, Sapphire, N. C. 
Corundum has been found at a number of the peridotite outcrops 
between the Bad Creek and the Whitewater mines; and while this 
does not by any means indicate thai there are large deposits of this 
mineral in these rocks, it does indicate, taking into consideration the 
corundum deposits already found northeast and southwest of these, 
that there is a possibility of such deposits, and it makes this section 
a promising one for systematic prospecting. 
GEORGIA. 
The corundum Localities of this Si ale are shown on the map (PI. V I), 
which also gives the general local ion of the peridotite formations thai 
have been observed in this section. Although there is considerable 
peridotite occurring in the northern portion of the State, ii is a1 but 
few places thus far that corundum has beeu found in any quantity, 
and these are at the extreme northern part, not far from the North 
Carolina line. 
Georgia corundum is well known, ami perhaps has the besl reputa- 
tion of any on account of thai obtained from the Laurel Creek mine, 
which, wiih the exception of the Track Rock mine, is the only one 
that has produced any considerable quantity of corundum. The 
peridotite formations are not so large as in North Carolina, nor are 
the corundum localities so numerous, and ii is not probable thai there 
is as much corundum in this State as in North Carolina, although 
the Laurel Creek mine may be superior to any one thus far located 
in North ( larolina. 
Laurel Creek mine. This mine, which is owned by the interna- 
tional Corundum and Emery Company, is Located at Pine .Mountain, 
Rabun County, Ga., and is is miles from Walhalla, S. ('., the near- 
est 1)011)1, on the railroad. Al this locality 1 here is a large outcrop 
of peridotite, covering several hundred acres, and along the contad 
of this with the gneiss large deposits of corundum have been found. 
Several openings have been made, some of which have been worked 
very extensively. Fig. 1_ is a topographic map of this peridotite for- 
mation, showing the general location of the cuts and shafts that have 
been made. As is seen from the map, the formation extends over 
two small hills, which, on account of their rough and barren nature, 
offer a sharp contrast to the surrounding country. There is a large 
open cut (1 in fig. 12) on the east side of the formation, which follows 
for the most part along the contact, is l'00 feet in depth at the lower 
end, and gradually rises until at the upper end the surface is reached.
