It should be stated that these lighter colored gneisses were 
at first regarded as varied forms of the Ocoee, but a final re- 
view of the sections, in the light of the J asper beds, warrants, it 
18 believed, the conclusions that follow. These conclusions 
briefly stated, are: 
Ist. That the plateau land of northeast Georgia is based 
upon a great synclinal in the Ocoee. 
d. That the Great Smoky Mountains may be regarded as 
the western monoclinal edge of this synclinal and the Blue 
Ridge as the eastern. 
dd. That the great mass of the strata lying between these 
mountain chains in Georgia are above and younger than the 
coee, and are composed chiefly of the metamorphosed equiva- 
lents of the Knox Group. 
4th. That the formations east of the Blue Ridge are the 
metamorphosed equivalents of the Knox Group. 
That the porphyritic gneiss of the W. & Atlantic rail- 
road section is identical with the porphyritic gneiss found near 
Talking Rock and is a form of the Ocoee. eae 
The second conclusion given above needs some qualification. 
Th the Ocoee Gorge in Tennessee there are several faults in the 
Ocoee which would cause a repetition of monoclinal edges be- 
fore the formation disappears as a final synclinal. This same 
characteristic marks the section of the Ocoee between Gregory’s 
and Mountain Town, and between Talking Rock and the Coosa- 
Wattee River. If the ridge east of Elijay is true Ocoee this 
general idea would require further modification as shown in 
the accompanying figure.

The fourth conclusion is based upon the facts: 
Ist. That Professor Bradiey regarded the limestone near 
Gainsville and Clarkesville, Ga., as of the same age as the 
Professor Tuomey as
