WELLS OF KANE COUNTY, ILLINOIS. 597 



In the vicinity of Richardson several wells have been sunk to depths 

 of 80 to 120 feet, mainly through till, and obtain water in sand and gravel 

 without entering rock. Mr. Richardson has two wells, one 84 feet, the other 

 87 feet; Mr. Dayton, one well, 117 feet; Mr. Frank Paul a well 120 feet. 

 Other deep wells in that township range from 50 to 100 feet or more, with 

 an average about 75 feet. Such wells are much stronger than those obtained 

 at shallow depths. 



In T. 40, R. 7 E., there is an elevated morainic belt in which the drift 

 probably averages over 200 feet. Each of the wells which enter rock pene- 

 trate more than 200 feet of drift, and one well reaches a depth of 336 feet 

 without striking- rock. In several wells an old soil is found at the depth of 

 about 200 feet, which in some instances is probably between the Iowan and 

 Illinoian drift or the Sangamon interglacial stage. The following wells serve 

 to illustrate the above statement. At J. Powell's, in sec. 7, altitude about 

 950 feet, buried soil is struck at 195 to 200 feet and rock is entered at 250 

 feet. The well is continued about 200 feet into the rock. At M. W. Powell's, 

 in sec. 8, on nearly as elevated a point as the preceding, a well about 500 

 feet in depth penetrates 234 feet of drift. At a cheese factory in section 19, 

 at an elevation of 950 feet, is a well 336 feet in depth which did not reach 

 rock. An old soil is found below the blue till at 198 to 200 feet, with a 

 greenish subsoil beneath it. A hard till of light gray color sets in at 240 

 feet and extends to the bottom of the well. Mr. Beith, in sec. 28, has a 

 well 228 feet in depth, which is thought to strike rock at the bottom. The 

 altitude is probably 925 feet. Mr. L. R. Read, in sec. 32, has a well 226 

 feet in depth, which passed through an old soil at about 180 feet and entered 

 rock at 214 feet. The altitude of the well is about 925 feet. 



In the vicinity of St. Charles in T. 40, R. 8 E., several wells have been 

 sunk to a depth of 75 feet or more. One in sec. 1 strikes a black soil below 

 blue till at a depth of 72 to 74 feet, and one on Mr. Dunham's farm, in the 

 east part of the township, passes through a buried soil at 75 to 78 feet 

 The altitude at these wells is about 750 feet, or nearly 200 feet below that 

 of the deep wells in the township on the west just noted. 



At Geneva a well at the. court-house was sunk to a depth of 2,500 feet, 

 and the Grlucose Company have a well 2,000 feet in depth ; this company 

 also has a well 400 feet in depth. No further data concerning' these wells 

 have been obtained. The village stands on a gravelly plain at a level
