MEDINA COUNTY. 379: 
the washing in of the pebbles derived from the true and older Conglomer-

A well marked glaciated surface is shown at the Mills’ quarry. The 
strice run south-east and north-west, the general dip of the glaciated sur- 
face being nearly ten degrees to the north-west. There is quite an extent 
of rock exposed along the road, affording an unusually good opportunity 
to see a continuous, well-marked glacier-planed surface. There are a few 
short, single striz which strike fifteen degrees more easterly, and were 
perhaps made by icebergs succeeding the glaciers which made the greater 
portion of the linings. The last-mentioned set are generally far apart, 
and usually but three to four feet long, while the glacial markings proper 
are continuous throughout the exposure, and are as true as “chalk lines.” 
Picturesque scenery characterizes this township, though several others 
vie with it in this respect. The western part of the township falls away 
into a well-marked valley—that of the River Styx—which is in all prob- 
ability the western limit of the coal fields. Some of the highest land in 
the State is in this township. A Locke’s level used on the range, east of 
the center, at a high point, one mile north-east of the town, showed no 
land along the horizon as high, though the ranges of Wayne and 
Summit counties were in sight. Basing my estimate on railroad levels 
in the township, we put this elevation at eight hundred feet above Lake 
Hrie. Mr. Sargent made a survey, for the Lake Shore and Tuscarawas 
Valley Railroad, through Wadsworth, and if the road had been built on 
his line, the summit level would have been one mile south-east of Wads- 
worth village, and five hundred and eighty-five feet above Lake Hrie. 
The south part of Wadsworth village is seventy-five feet higher than 
Medina Square. 
Whetstones have been manufactured quite extensively from rock taken 
from the bed of Mineral Run, on land owned by Mr. D. W. Hard, located 
on the north border of the township, and one hundred and sixty rods 
east of Guilford line. Two hundred and twenty-five thousand pounds of 
whetstones have been manufactured by Messrs. Reynolds, Sisler & Co., 
of Manchester, Summit county. This stone is called an “oil and water 
stone.” It was worked into all shapes required by the market, some 
of it meeting the demands of surgeons and dentists. The three layers 
of stone found at the locality vary in fineness and softness, the lower 
ones being coarser and harder than the upper one, which was mostly 
worked up into hones, etc. The average thickness of the three layers is 
four inches. Spirophyton Caudagall, fucoids, and Produck were seen in 
this quarry. |
