conglomerate and very few continuous beds of red shale.
The conglomerates are as coarse as farther north but
there are more granite pebbles. The sandstone here
as farther north are excessively cross bedded with
very short lenses of red shales.
On the other side of Sand River the beds again
dip to the north.
Apple River, July 14-1912 Sunday.
After a late breakfast started out in a buggy
for Eatonton about 8 miles south of this place
to see Fletcher's Devonian. When we got there
we soon found the outcrops in the small river, &
forced to be a green schist which to me looks like
a chloritic schist. It is penetrated by a red or an
lilac crystalline leucogranite igneous material. The schists are
initially a metamorphosed igneous rock that has
undergone very decided pressure. There is nothing of
a Devonian character in this schist and it is probably
of Pre-Cambrian age. The dip given in the Devonian
are planes of schistosity and not of bedding.
In the room at Eatonton maybe seen the contact.
