F. H. Bradley—WSilurian age of the Southern Appalachians. 871 
material as an ornamental stone is still further diminished by 
the frequent dissemination of small grains of quartz through the 
mass, which prevent a perfect polish. At some points along 
Red Marble Creek, especially near its mouth, we find large por- 
tions of the marble even shaly, with tale or chlorite, or both, and 
very much disturbed and intermingled with chlorite schists. 
Some of these impure portions are of a rich chocolate brown. 
On the mountain-side, northwest of the creek, ascending the 
road leading from its mouth across to the head of Tallula Fork of 
Cheowa, we find a second outcrop of the marble, mainly blue 
and bluish-white and partly chloritic, held in the trough of a 
small subordinate fold, as was suggested with respect to the 
disturbed strata between Valley River and Cheowa. Higher 
up, the underlying chlorite slates are so much distorted that, at 
one point, dips of 8. 60° E. and S. 5 . were noticed within 
ten feet of each other, in the solid strata. 
The local fold just mentioned seems to be converted into a 
fault, as we pass southwestward, toward Valleytown. The main 
line of marble-outerop, passing through Red Marble Gap, runs 
by Swepson’s and Ingraham’s localities, making deep and long 
hollows as it crosses the mountain-spurs, crosses Junaluska 
Creek, near Valleytown, and apparently continues nearly to 
Paint Creek, where the overlying pyritous and micaceous lime- 
stone outcrops, just southeast of the fault. Higher up, as on 
Junaluska Creek, the marble is underlaid by siliceous, chloritic 
and hydromica schists, of the age of the Knox shale, followed 
below by gneisses, partly schistose, partly quartzytic, represent- 
ing the Knox and Chilhowee sandstones, which latter form a 
high ridge, for several miles, between this lead of marble and 
the upper part of the Valley River valley. On the northwest 
side of the fault, the marble makes its appearance about a mile 
above Valleytown, outcrops at several points near Whittaker’s 
Ouse, where a little quarrying has been done, and continues, 
apparently without interruption, down the valley to Murphy, 
where it crosses the Hiwassee. Thence, crossing the lower 
course of Notla River, it crosses the lower part of Hemptown 
Creek, then crosses the Ocoee River and continues to the White 
Path gold mines and Ellijoy, in Gilmer County, Ga., where we 
shall meet it again. The line thus traced is, in direct course, 
Over sixty miles in length. Without more detailed surveys 
along the whole line, we cannot be sure that there are no other 
breaks in its continuity ; but, as thus far known, the Valley- 
town fault appears to be the only very important one. Just 
Opposite Valleytown, a partial break exposes another outcrop of 
the underlying gneiss, between Whittaker’s and Collett’s ; but 
the two strips of the marble are united, as they pass southwest- 
ward, at perhaps ten miles below Valleytown. In this neigh-
