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. 



GKANGER 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 ofif 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-
