"the regultion Ohio Richmond beds only
Rhynchotrema capax. These beds are seen
in two cuts representing a thickness probably of
not less than 150 feet.
As far as this section goes lithologically,
all appears to be conformable as an unbroken
sequence. The last of the Richmond becomes mag-
nesian, lighter colored and seems to shade over
into the Silurian. However the lower Richmond
beds already give way to shales in which Corbulus
arphoid. There are no transition beds to these
shales and yet all appears to be a sequence.
Immediately above the thin dolomites have underlaid
higher
Kicjaran beds of the interin type.
Purchased 4 photos showing the outcrops in the
R. R. cut and the staging tracks.
Left at 2:15 for Battle Ground and due at 4
for Louisville.
