MEDINA COUNTY, 365 
It is here nearly a pure sandstone, the quartz pebbles being compara. 
tively rare. The product of the quarries in the rocky ravine two miles 
north of the Center is variable, some of the stone being a fine white grit, 
while much of it is badly stained with large dark patches. 
CHATHAM TOWNSHIP. 
The general level of this township. is much below that of the three 
which lie east of it. There is a rapid fall from the center road to the 
west amounting to nearly two hundred feet in the three miles to the east 
branch of Black River. 
The Cuyahoga shale is exposed on Gray’s Creek, which flows along the 
western border of the township, and empties into Black River near the 
east and west center road in Spencer. The upper strata are of very hard 
shaly sandstone, quarried for foundations. The gray soft shale below is 
much like that on Rocky River below Abbeville, and contains similar 
lenticular concretions of iron, but the limestone concretions are here very 
few. The fossils are not well enough preserved in this shale to be of 
value as cabinet specimens. The under surfaces of the thin layers of 
shaly sandstone, which occur every few inches in these beds, show abund- 
ant tracings of fossil forms, but none of them are distinctly marked. A 
bowlder, estimated to weigh eleven or twelve tons, can be seen in the 
bed of Gray’s Creek. 
GRANGER TOWNSHIP. 
The Conglomerate underlies all of Granger, as it is one of the town- 
ships in the most easterly range of the county. There are abrupt ledges 
on lots 39, 41, 42, and 98. Quarries have been opened on lots 42 and 78, 
and also on lot 38. Along the west line of the township there is a sand- 
rock which comes near the surface, and may be seen on lot 50, and is 
doubtless referable to the upper layers of the Cuyahoga shale. 
An ancient fort stood on land a half mile east of Grangersburg; it is 
now but an indistinct remnant of the original fortification. It once con- 
sisted of a circular trench with embankment, and was, perhaps, ten rods 
across, the northern extremity being now cut off by the public road. A 
perpetual spring fed a small stream which flowed along the base of the 
wall. 
GUILFORD TOWNSHIP. 
The Coal question is one of special interest in Guilford township, which 
is the first one west of Wadsworth, where are three coal mines in full 
operation. The River Styx Valley lies between the townships. The 
altitude of Guilford is less than that of Wadsworth, being at Seville Sta-
