10) N of Berea to RR cut & stream b.
Crossing 2 3/4 mi. N of Berea,
The dip as shown by Dev = 33 ft. in
two miles going southward.
Near Berea the dark brown recrystallized rock of S.M sections, reveals
the cleety Dev. This bed was not
noticed at RR cut. nor was the
cleaty layer near there.
The RR cut is 2 1/2 mi's N of Berea.
The Devonian limestone is here
5 ft thick; 20 inches above the base
fish teeth are very common in the
bottoms of one of the limestone
layers. Fish plates are also common.
4 ft of greenish slaty clay are ex-
pried below the Dev. The total thickness
of this clay is believed to vary between
10 1/2 and 13 1/2 feet judging from
the absence of limestone exposures
at this level along the RR.
13 feet of limestone with interca-
lated clay beds Section along the
RR + less reliable than would be a
vertical section. Differs as leads:
1 ft Limest layer with Platystrophia
biforata, Streptinlynelmus, plant
form corals. Relicites and shell
tus. Large crinoid beads.
3 1/2
6 in reddish brown limestone in clay at
top are large crinoid beads Stelf--
1670
tubasina calyculata,
Madison top at 939.

Near Berea 1/2 mi. N of railroad to
Corrife, or l. is 8 1/2 ft thick. Near
top it becomes very cleety. Towards
the base it is not very sparingly cleety.
Overlying the same cleaty layer at
tooths is this recrystallized dark blue
Dev limestone. Judging from beds
dev scattered in the fields the thick-
ess of this recrystallized rock nearly,
is not quite, equals 5 ft.
Exposures on west side of RR,
north of a culvert, where a stream
passes beneath a culvert.

At the RR cut 2 1/2 mi. N of Berea
there is no recrystallized place by the
Dev discernible; nor is there any
cleaty bed. There is not a trace of
crust present at mine corral?
Nothing resembling the heavy
cleety beds seen near Berea.
The total Dev line is 5 ft thick
