406 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



along the line leading direct from Mansfield to Fredericktown, and a coating 

 of drift 10 to 20 feet thick was found to be quite generally prevalent. On 

 a prominent point about 3 miles north of Bellville, aiid perhaps 1,450 feet 

 above tide, a well at Mr. Shickler's reached rock at 18 feet, and on points 

 about the same altitude, south of Bellville, wells penetrate several feet of 

 drift. One-half mile north of Palmyra, on comparatively low ground, a 

 well at C. Snyder's, 67 feet deep, penetrated considerable till and entered 

 gravel near the bottom South from Palmyra the drift is much thicker than 

 it is to the north. Passing west to the less elevated country the thickness 

 of the drift increases, and where morainic features set in near Darlington it 

 is generally 50 to 60 feet, or even more, in depth. Gr. McFerrins's well, near 

 Darlington, has a depth of 61 feet without reaching rock. It penetrates 

 much till. 



In Fredericktown rock is exposed along the east side of Owl Creek, and 

 the creek here crosses a rocky point which extends westward slightly beyond 

 the railroad track, making a rock cut necessary south of the station, Mr. 

 Cummings's well in the village, at a level about 60 feet above the station, 

 struck no rock at a depth of 80 feet; but just east of this well, on- equally 

 elevated ground, overlooking Owl Creek, Wesley Whitford has a well which 

 struck rock at 25 or 30 feet. The wells in Fredericktown usually obtain 

 water at about 40 feet from beds of gravel between till sheets. 



For several miles west of Fredericktown the preglacial ridges and 

 valleys are quite effectually concealed by heavy deposits of drift, but from 

 Fredericktown eastward the drift sheet is thin, its general thickness being not 

 over 25 feet. It maintains a nearly continuous sheet up to the very border 

 of the neck of apparently driftless land, that has already been described as 

 leading from Independence eastward to Mohican Creek. 



In the village of Jelloway, which is near \he south border of this neck, 

 flowing wells have been obtained from the drift at a depth of about 40 feet; 

 and at Mr. Ricliert's, 2 miles west of Jelloway, a flowing well 50 feet deep 

 was obtained without reaching rock, while a well on higher ground at his 

 residence struck I'ock at 50 feet. These wells are practically at the border of 

 the nearh' driftless neck, there being scarely any drift on the uplands north 

 of Mr. Richert's or at Jellowa}'. They are, however, in valleys, and show, 

 a larger amount of drift than the uplands adjacent to them. The drift 

 penetrated in these flowing wells is said to be a pebbly blue clay.
