CHAPTER XXXVI. 
REPORT ON THE GHOLOGY OF MORROW COUNTY. 
BY N. H. WINCHELL. 
SITUATION AND AREA. 
Morrow county is situated very near, but a little north, of the center 
of the State, and was among the first settled, the first inhabitants coming 
largely from the New England States, and from New York and Pennsyl- 
vyania. It is bounded on the north by Crawford and Richland counties, 
east by Richland and Knox, south by Knox and Delaware, and west by . 
Delaware and Marion. Its form is nearly that of a rectangle, lying 
north and south. Its western boundary is broken by its wanting a town 
in the north-west corner, and by its inclosing Westfield in the south-west 
corner. Its area, given by the State Board of Hqualization in 1870, is 
253,149 acres, of which 83,698 acres are arable, 91,045 acres are meadow 
and pasture land, and 78,406 acres are uncultivated or wood land. The 
average value, exclusive of buildings, is $30.40 per acre. 
NATURAL DRAINAGE. 
The most of the drainage of the county is into the Scioto river. Its east- 
ern portions are drained into the Muskingum; yet the Sandusky, which 
flows into Lake Erie, has some of its sources in the township of North 
Bloomfield, in the northern portion of the county. The streams are not 
large, but are ample for most purposes in an agricultural community. 
Many flouring mills exist in the county, the motive power being 
hydraulic. 
SURFACE FEATURES. 
The undulations in the rocky structure are usually very gentle, even 
imperceptible, through the Drift sheet. Hence the general surface was 
originally nearly flat. The unevenness that now prevails in some parts 
of the county is mainly due to subsequent causes, and can be referred to 
the known effect of atmospheric forces. The eastern half of the county 
is decidedly rolling, and even hilly; the western half is more level. The 
Drift was at first deposited with unequal thickness, whateyer may have 
been the condition of the pre-existing surfaces. In the valleys of those 
streams that flow toward the east, in the eastern part of the county, there
