A well marked glaciated surface is shown at the Mills' quarry. The 

 striae 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 striae 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 

 Brie. 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 Erie. 

 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, sonae 

 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 Caudagalli, fucoids, and ProducU were seen in 

 this quarry.
