ville, Montgomery County, is reached, only a single layer remains. 
It occupies the position of the lowest, but whether or not it is one and 
the same layer or different layers at the various exposures to the south- 
ward cannot be determined. From its position in the following 
section, which was taken one mile east of town, it will be seen to 
occupy the position of the “City ledge.”

Black shales extend to the level of Slate Creek at the 
bridge, but these were not measured. 
Still farther south the lower layer finally disappears. In place 
of the Buena Vista sandstones, soft, argillaceous shales occur in the 
lower Cuyahoga. To these clayey shales, August F’. Foerste applied 
the term “Linietta clay,’ provisionally, before their identity with 
the New Providence shale of southern Indiana was ascertained." 
The New Providence shale with the overlying Riverside sandstone, 
it will be recalled, make up the Knobstone formation of Indiana. 
About Indian Fields in Clark County, the Ohio shale extends to 
near the top of the hills. One mile east of the station, along a highway 
passing within a quarter of a mile of Oil Springs, the following section 
was taken. The chief interest in this one is, that while the Bedford- 
Berea is only two inches in thickness, the shales are fossiliferous. 
More will be said about these fossils after the Irvine section has been 
given.
