line, joining this outcrop with the synclinal noticed at Long 
dge on the other route. Northwestern dips of the Ocoee now 
continue on to the head of the river, consisting of hydromica 
schists and gneisses with staurolites and garnets, chlorite schists 
with garnets and quartz veins, and some bands of gneiss and 
quartzyte. As we approach the summit gap, toward Valley- 
town, we find an irregular anticlinal, equivalent to that at 
Davidson’s on the other route, followed by very confused dips, 
as though the mountain bed suffered a tremendous squeezing in 
this region. These disturbed foldings continue even down to 
the valley-level, where sharp anticlinal folds occur in the mica- 
Ceous gneiss, just before it dips beneath the Knox marble. It
