certain highly fossiliferous beds occur. They have been worked 
for fossils quite carefully in Medina, Ashland, Licking, Ross, 
ike and Scioto Counties. It seems probable, at least, that the 
Lodi, Ashland, Granville and Sciotoville fossils all come from 
the same horizon. 
The Buena Vista Stone, that overlies by a few feet the 
Waverly Black Shale on the Ohio River, and with which the 
‘Grit of Northern Ohio was identified by the erroneous 
reference of the Waverly Black Shale named above, proves to 
much more local in its character than the other elements. 
It has not been found to hold as a continuous stratum as lar 
north as the center of the State.

A conglomerate covers the Cuyahoga Shale both in Northern 
and in Southern Ohio. It has b 
tions the Carboniferous conglomerate, but in Licking, Knox 
and other counties, the same fossiliferous stratum that under- 
lies it constitutes the base of the Waverly conglomerate of 
Andrews, which is there separated from the Carboniferous con- 
glomerate by one hundred to two hundred feet of the Logan 
sandstone of the same author. Without undertaking to clear 
up the confusion of the two conglomerates throughout the field, 
I venture to suggest that a satisfactory explanation for South- 
ern Ohio seems to be found in the fact that upon the extreme 
western border of the coal-measures, the two conglomerates are 
unconformable by overlap, the Logan sandstone being greatly 
reduced and perhaps disappearing entirely, and the conglome- 
rates thus coming to be considered as one.
