given them this name. This peculiarity is more decidedly exhibited 
in the Bedford shales of the county, as some of the sections hereafter | 
given will show. The dip of the strata is irregular. At the quarry 
worked by W. R. Starr, south of Clarksfield village, along the line bear- 
ing south 60° east, the rock dips to the north 11°. Fifteen rods north the 
dip is 7° in the opposite direction. Half a mile west of this locality, 
in another branch of the Vermillion, the dip is as represented in the 
subjoined wood cut: .

Following the above exposure toward the east, we find the flexure 
indicated below: 
The lines of fracture are substantially parallel with the line of strike 
Here, as elsewhere in the county, this disturbance is superficial, not in- 
volving the deeply buried rocks, and is the result of lateral thrust, the 
action of that slowly moving, resistless force, which has broken up and 
displaced nearly all the surface rocks of the county, and has crushed to 
the center the high rock hills in the counties further north. 
Just north of New London township, in Ashland county, this super- 
ficial disturbance of the strata is shown in an exposure of the Cuyahoga | 
shales near the north and south center roads. There the soft, flexible 
shales are crowded up, as represented in the figure given below, until 
the strata incline at an angle of 45°. They were becoming level again, 
however, at the west, and the disturbance evidently involves the super- 
ficial strata only.
