mens at a number of localities in this county, and at one place in the 
peridotite formation. There have been no developments and there 
are no indications of any quantity. 
Hamilton mine. — The corundum occurs in a peridotite formation 
about 5 miles north of Young Harris, Towns County. No large 
quantity lias been found. 
Hog Creek mine. — This mine is 2 miles a little south of west of 
Hiwassee, Towns County, but it lacks development. The corundum 
is associated with peridotite, and is pink, blue, and white. 
Laurel Creek mine. — In peridotite. (See p. 63.) 
Monroe. — Four and a half miles from Monroe, Walton County, on 
the farm of George W. Breedlove, black corundum has been found 
associated with peridotite rocks. Some Little prospecting done here 
has been within the formation and some near the contact. 
Pine Mountain, Rabun County.— In peridotite. (Sec p. 63.) 
Porter Spr xng s. — One mile southeasl of this place (in Lumpkin 
County) corundum has been found in an amphibolite, bui there is no 
quanl it v. 
Powder Springs. — There is a considerable outcrop of peridotite in 
Cobb County, in the vicinity of Powder Springs, which offers a prom- 
ising place for prospecting. A small vein has been opened on the 
\Y. Ii. Turner farm. 
Rabun (r(ij>. — Several pounds of corundum have beeil obtained 
from the Beavetl mine; ii occurs in a peridotite rock. 
Teltonville. — One mile uorth of this town, in Forsyth County, sur-

in the quartz-schists of this region. 
Stone mine. — This mine, which is in the same general formation as 
the Track Rock mine (see p. 65), is in Rabun County. Only a little 
development has been undertaken and the prospect that the deposit 
may be valuable is not very favorable. 
Thomaston. — Seven to S miles southwest of Thomaston, Upson 
County, considerable corundum has been found on the surface at the 
old Kelly farm. Some of the specimens of the corundum in the 
matrix indicate that ii was derived from a mica-schist. 
Track Rock mine. — -In peridotite. (See p. 65.) 
West Point. — A short distance northeast of this town (in Troup 
County) corundum has been found sparingly in a narrow strip of
