376 i 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 rounded 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 abound 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 afew 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. | 
The Mineral Paint made from the shale in the south-western part of 
the township 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 somuch broken up. Clay soil and level surface, such as 
characterize southern Lorain, are the predominant features in Spencer. 
lt 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 Owyahega 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 
Centér 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.
