382 GEOLOGY OF OHIO. 
Miami, at Ceesar’s Creek, to the same valley, north of Deerfield, shorten- 
ing the distance between these two points by more than eight miles. 
This is one of the lines by which Lebanon has sought railroad connec- 
tions. 
On the east side of the Little Miami, the valleys of Cesar’s Creek and 
Todd’s Fork are the only ones of considerable importance. Both streams 
take their rise in the flat track of Greene and Clinton counties, from 
which they descend to the Miami in a south-westerly course. 
The dividing ridge between the two Miamis, already referred to, holds 
the highest land of the county, the altitude increasing towards the — 
northern boundary, where it reaches its maximum of about 625 feet 
above low-water, at Cincinnati. The highest land measured in the county 
is the summit of William Morris’s hill, on the boundary-line between 
Wayne and Clear Creek townships, one mile east of Utica. This has an 
elevation above low-water at Cincinnati of 595 feet. The ridge in these 
same townships, occupied by the Harlan, Tibbals, Stokes, and other 
farms, has, certainly, somewhat greater elevation. 
The lowest point of the county is found at its southern boundary, 
on the Little Miami River. The railroad track, at this point, has an 
elevation of only 150 feet above low-water at Cincinnati. The bed of the 
stream at the point named is not more than 125 feet above the same base. 
The vertical section of the county, then, embraces 500 feet. | 
Geological Scale—The geological scale of the county is identical in its 
elements with that of Montgomery county, described in the first report 
-of the Survey, and with that of Clarke county, figured in the previous 
volume. The 500 feet already given as making the vertical scale of the 
county, are divided among the three formations there named in the fol- . 
lowing order, viz:

county.

in this group, will need to be recalled. This system of rocks, which has 
an aggregate thickness of nearly eight hundred feet, is divided into three 
divisions, viz:
