320 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



A mile or more east of Rialto, near the east side of the valley, is a well 

 about 35 feet deep located on a knoll perhaps 15 feet in height. It passed 

 through assorted material in its upper part, but the lower part penetrated 

 blue pebbly clay. 



In Sharonville wells penetrate about 20 feet of till, and at that depth 

 obtain water from gravel. On Mr. Ferris's farm, IJ miles west of Sharon- 

 ville, on the west side of the canal, a well penetrated the following beds:

On J. Brown's fai-m, 1 mile southeast of Sharonville, wood Avas 

 encountered in blue till at a depth of 20 to 40 feet. At the gas-well 

 boring in Lockland, in the valley of West Mill Creek, the surface being 

 fully 30 feet lower than the upper lock in Lockland, or about 546 feet 

 above tide, drift was penetrated to a depth of 190 feet, showing the rock 

 floor of the valley to be but 356 feet above tide. This, so fai- as known to 

 the writer, is the lowest altitude of rock floor yet found in the valley. The 

 exact section was not recorded, but Mr. Latty, of Lockland, who was inter- 

 ested in sinking the well, made the following statement from memory;

At Stearns and Foster's cotton mill in Lockland, near the upper lock, 

 a well whose surface is 565 feet above tide is 147 feet in depth, and did 

 not reach rock, but terminated in sand beneath a thick bed of blue clay. 

 At Wyoming the city well (whose mouth stands 600 feet above tide) pene- 

 trated 155 feet of drift without reaching rock, there being yellow and blue 

 clay, gravel, and bowlders in the upper 84 feet, and sand in the remaining 

 71 feet. 



A short distance south of Wyoming and Lockland, on the west side of 

 Mill Creek Valley, the Cincinnati, Hamilton and Dayton Railway was, at 

 the time of a visit in October, 1889, making a cutting for a switch between
