376 GEOLOGY OF OHIO. 



the Philip King farm, two miles south-east of Medina village. It is 

 nearly midway between Rocky River and Champion Brook, and perhaps 

 fifty rods above their junction. The mound is now ten feet high, and 

 some seventy feet in diameter, though centuries of washing and several 

 years of plowing have extended its borders and rouuded its outlines. The 

 soil of the mound is different from that of the "bottom land " on which 

 it is built. The nearest ridge or bank is about thirty rods distant. Flint 

 arrow-heads abouad on the surface about the mound. 



SHARON TOWNSHIP. 



The Coal Measures extend into Sharon township from Wadsworth, 

 which lies immediately on the south. Borings have shown the presence 

 of coal in the south-east and south-west corners of the township. 



The Conglomerate shows extensively in ledges which are crossed by the 

 north and south State and Center roads, two miles north of the south 

 line. There are perpendicular bluffs of Conglomerate along Spruce Run, 

 and it is shown to some extent in lot nine at the north of the township. 

 George W. Crane, Esq., owns a quarry of the rock situated a little north- 

 east of the Center. There are no large pebbles in the stone, and 

 only a few very small ones. Mr. Glenn Freeman's south lot line on the 

 Center road is on the highest land in the township — over one hundred 

 and fifty feet above the village. The west part of the township has 

 much heavy clay; the eastern part is loamy. e 



The Mineral Paint made from the shale in the south-western part of 

 the towfiship is a valuable commercial article. 



SPENCER TOWNSHIP. 



Lying as it does at the extreme western border of the county, Spencer 

 township differs much from the territory in the eastern portion where 

 the surface is so much broken up. Clay soil and level surface, such as 

 characterize southern Lorain, are the predominant features in Spencer. 

 It also forms the lowest portion of the county. Between the soil and the 

 Drift clay is a variable layer of sandy loam. The north-eastern quarter 

 of the township affords a few exposures of Cuyahoga shale in the banks of 

 the East Branch of Black River. 



Gas springs have been observed in the river. 



Salt is indicated in the wells and springs which are found on a narrow 

 belt of land running westwardly, and about eighty rods north of the 

 Center road. The percentage of salt in the water is small, yet it was 

 enough to interfere with the working of a steam-boiler, producing saline 

 incrustations upon it. Salt licks are known in the township along this 

 belt of salt territory.
