CHAPTER LXIX. 
REPORT ON THE GEOLOGY OF MEDINA COUNTY. 
BY ALFRED W. WHEAT. 
Medina county is bounded on the north by Lorain and Cuyahoga, on 
the south by Wayne, on the east by Summit, on the west by Lorain and 
Ashland counties. 
There are seventeen townships in the county, containing collectively 
four hundred and fifteen square miles. Like most of the ‘‘ Western Re-

portions in the north-western part of the county have an altitude of 
from two hundred and fifty te three hundred feet only above Lake Erie.

the streams flow both to the north and the south, eventually finding the 
St. Lawrence and Mississippi Rivers. There is but one lakes in this 
county, Chippewa Lake, the extreme length of which is one mile and a 
half. 
The soil in the western portion of the county is mostly clay. In 
Harrisonville township two thousand acres are covered with peat. 
The indigenous forest trees upon the clay lands are elm, beech, maple, 
oak, hickory, linden, black walnut, butternut, and, in the river bottoms, 
sycamore. Chestnut trees are prevalent along the ledges and sandy
