Fic. 4.—Berea grit with superjacent Sunbury shale in quarry No. 9, at Berea. 
This section shows that there is not such a marked and sharp 
lithologic change from the Sunbury to the Cuyahoga shale as is 
found in the bluffs of the Ohio river or is shown in sections 
farther east, but a more gradual transition. This quarry is shown 
in Fig. 4, the greater part of which is the Berea grit, but capped 
by the Sunbury shale, and fossils are abundant in the zone indi- 
cated by the man.
