The lithological character of the Cuyahoga shale is quite variable, 
ranging from a very soft shale to a hard argillaceous sandstone. Some 
of it, by exposure to weather, separates into thin, tough sheets, but the 
greater part crumbles down into clay. A few beds contain lenticular 
concretions of lime and iron. The rock is usually gray in color. The 
shade, composition, and hardness differ very greatly in successive layers. 
The Hconomic Geology of Medina county makes no great show. The 
mineral wealth of the county lies chiefly in coal. Of iron stone there is 
but little, and that contains only a small per cent. of iron; and of lime 
there is a notable lack. Gas springs are known in nearly every town- 
ship which is immediately underlain by the Cuyahoga shale, but in no 
case has this gas been utilized. oi 
While traveling about the county I not infrequently had persons 
whisper in my ear, with great caution, the word “lead;” and I found 
several tracts of land under lease to parties who were confident that they 
should develop large deposits of galena. My own work with hammer 
and chisel in a secluded ravine or by the roadside would at times call 
from a passer by this question: ‘Stranger, are you prospecting for 
lead?” All parties were assured that such a search would be quite 
profitless. Small quantities of galena are found among the fossils of the 
Cuyahoga shale at Lodi and Weymouth, but only small quantities. 
For particulars concerning the quarrying of building stone, and the 
manufacture of mineral paint, reference may be had to the following 
notes on the several townships: 
BRUNSWICK TOWNSHIP. 
The soil of Brunswick is largely clay. Wells dug near the Center do 
not pass through the gravel Drift. James Woodward makes this state- 
ment about a well which he dug fifty rods north of the Center: Below 
the alluvium there were twelve feet of yellow clay, and below the yellow 
clay the well was dug forty-two feet into blue clay, which contuined a 
little gravel throughout. This may be called a sample of ail the wells 
dug near the Center. } 
The Conglomerate appears further west in Brunswick than in any other 
township. The extreme western limit is perhaps one hundred rods west 
of the north and south center road, in the upper part of the township.
