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 Economic 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. 



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 contained a 

 little gravel throughout. This may be called a sample of all 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.
