pebbles entering into the composition of the breccia in Tennes- 
see was not examined. In the masses found in this hill near 
Cartersville barite was a notable constituent. This hill was 
succeeded by a wide valley in shale. Last of this valley and 
bordering the Etowah River a second ridge was passed through, 
showing in the railroad-cut a light colored decomposing 
siliceous gneiss dipping 45° EH. This gneiss seemed the un- 
from the decomposition of iron-bearing rocks. Succeeding 
- this the road skirts the base of a lofty hill (500 feet), com- 
posed entirely of dense quartzite. This occurred in the 
horizon of the Chilhowee and was regarded as its equivalent. 
Beyond this, near Stegalls a long eut was passed in shale. 
Decomposing masses in this shale were of the same texture 
and nature as the masses observed in the hill near Cartersville. 
After passing Stegalls, and just before reaching the Bartow 
Iron Works a cut in heavy shale showed a layer of very dark 
colored slaty shale. South of the Iron Works a vertical 
strata of the same dark colored slaty shale filled with conform- 
able quartz seams was found. Just south of this a very bigh 
hill showed the same shale more siliceous and metamorphosed 
into a very hard micaceous gneiss containing large quartz 
masses. In a cut, before reaching Allatoona, vertical walls were 
found, composed of quartzitic gneiss with slaty layers, the 
slate dark colored. Two cuts beyond Allatoona showed, the 
first, a schistose chloritic shale bed; the second very dark slaty 
shale containing quartz masses. From the sharp and rugge 
topography of the country, and the quantity of very dar 
slaty shale, the strata passed oyer since leaving Stegalls were 
supposed to be the equivalent of the Ocoee. The formations - 
were all conformable with dips varying from vertical to S.E. at 
high angles. ss 
In the second cut beyond the last a massive porphyritic 
gneissoid rock was found. Upon its weathered surfaces this 
rock presented a mottled appearance, and upon fracture show 
the Ocoee. (A rock with identical characteristics was found 
afterward near Talking Rock, Georgia, on the eastern flank of 
the Coosawattee Hills.) This rock was met with in three Sue 
cessive cuts. 
Succeeding this formation the topography of the country
