dip, Time did not permit the tracing of this formation 
towards the Blue Ridge, but from the dip of the gneiss bed at 
Cexsar’s Head the most plausible conjecture seemed to be that 
the dove-colored gneiss was above the former and therefore 
younger. This conjecture is strongly supported by the facts 
tevealed in See, 4. 
Section IIL—From Cartersvit.E To Acwortu, GEORGIA. 
This is a short section along the W. & Atlantic railroad. 
To understand the relations of the formations passed over, it 
Sweeps southward from Tennessee into Georgia. As it enters 
Georgia the trend of the formation is almost due south, The 
formation retains in Georgia the characteristic topography that 
marks it in Tennessee. The dolomite gives low cherty ridges; 
the shale, wide valleys. As will be seen in section 4th, when 
the Knox sik was traversed from Dalton to the Smoky

sandstone was accounted for by the supposition that the sand- 
Stone had likewise passed into a more shaly condition resulting
