WELLS OF COOK COUNTY, ILLINOIS. 585 



township (sec. 22, T. 42, R. 9 E.). This boring- reached a depth of 315 feet 

 without encountering- rock or obtaining water. As the altitude there is 

 about 825 feet, the boring reached a level only 70 feet below that of Lake 

 Michigan. Another boring 5 rods distant obtained a strong well from 

 glacial gravel at a depth of 170 feet. Between this well and the city of 

 Elgin several wells are found to enter rock at depths of 220 to 240 feet. 



Two wells east of Elgin are reported to have passed through an old 

 soil beneath the till. In one well the soil occurs at the base of the drift at 

 a depth of 67 to 70 feet. In the other it occurs at about 165 feet, while the 

 rock is entered at 192 feet. The wells in that vicinity penetrate a bluish 

 till, but on the borders of Fox River a brown or reddish till is reported to 

 extend to considerable depth. 



A well one-half mile west of Spaulding Station, 137 feet in depth, 

 enters rock at 120 feet. The drift is mainly blue till. 



At Bartlett several wells reach a depth of 90 or 100 feet, mainly 

 through till. At Ontarioville the wells of greatest strength are found at 

 depths of 60 feet or more, and occasionally reach 140 feet without entering 

 rock. 



In Palatine Township a large number of deep wells have been sunk, 

 partly because of the difficulty in obtaining water at shallow depths and 

 partly for the purpose of obtaining an overflow. At the time of the writer's 

 visit to that township, in 1887, there were not less than 25 flowing wells. 

 The}^ are located principally in the central portion, near the village of 

 Palatine, but occasional flows are obtained in other parts of the township as 

 well as in neighboring townships. In the southwest part the altitude is too 

 great for a flow, but several wells have been sunk there to depths of 150 

 to 180 feet without reaching rock. The following wells in the village of 

 Palatine serve to show the differences in depth of the wells and the relation 

 to rock strata:

The well at the cheese factor}^, when first made, would rise into the 

 second story, and that at the flax mill to a level 10 feet above the surface.
