60 CORUNDUM IN THE UNITED STATES. [bull. 180. 
There are four tracts included under tjbds head, which are described 
below. 
The Scaly Mountain tract is near the headwaters of Beech Creek, a 
prominent eastern tributary of the Tallulah River, on the southern 
and southwestern slopes of Scaly Mountain, at the elevation of about 
4,500 feet. The corundum-bearing bands of schist have been traced 
for the distance of about 2 miles, with a general strike of N. 40° E. and 
with a dip approximately 20°-30° NW. Considerable prospecting has 
been done in tracing this band of schist, but experiments show that 
there is less than 5 per cent of corundum in this schist, although some 
specimens have yielded 12 per cent. The latter were probably pieces 
broken off along planes of lamination of the schist, while the rest of 
the piece from which they were broken off carried but little corundum. 
The Foster tract is in Georgia, about 1J miles from Seal} 7 Moun- 
tain, and the State line forms its northern boundary. It is on both 
sides of Falls Branch, one of the smaller western tributaries of the 
Tallulah River, and is about 3,500 feet above sea level. Here a num- 
ber of pits have been made and samples of corundum have been 
obtained which have assayed on an average about 5 per cent of this 
mineral. There is more garnet associated with the corundum in this 
ore than in that from any of the other localities. 
The Yellow Mountain tract is on the north of Scaly Mountain, on the 
northern slopes of the Yellow Mountains. No prospecting has been 
done here, and from the indications the ore is the same grade as at 
the other localities. 
The Chunky Gal tract is at the summit and along the western 
slopes of the Chunky Gal Mountains, near the headwaters of Sugar 
Cove Creek. With a few interruptions, the corundum-bearing schist 
lias been traced for over 2 miles, with a strike and dip approximately 
the same as on the other tracts. A number of pits and cuts have been 
made, from which considerable ore has been taken out and tested, 
and the tests show the percentage of corundum to be practically the 
same as at the others. 
The corundum bands of the schist in all the tracts vary consid- 
erably in width, some being not over a foot or two wide, while others 
are 18 feet. In these wider bands, however, there are apt to be bands 
of the normal schist. More or less garnet has been found associated 
with the corundum in all the schist, and if in any amount would have 
to be eliminated or it would prevent any commercial corundum 
obtained from these ores being used in the manufacture of the vitri- 
fied wheel. 
From the extent of the corundum-bearing schist, there is undoubt- 
edly a large quantity of corundum in this section, but the low percent- 
age of corundum in the rocks makes it very questionable whether they 
can be profitably worked.
