596 THE ILLINOIS GLACIAL LOBE. 



1,876 feet in depth, which apparently obtains the greater part of its water 

 from the St. Peter sandstone at 650 to 700 feet. The heads at the several 

 wells vary from 716 to 742 feet above tide, the lowest head being at the 

 creamery and the highest at the watch factory well. An analysis of the 

 water from the well at the Hospital for the Insane is published in the 

 Seventeenth Annual Report of this Survey. 1 



A well on the farm of Judge Wilcox, northwest of Elgin, in sec. 4, 

 T. 41, R. 8 E., 127 feet in depth, passed through an old soil at 111 to 114 

 feet and obtained water without entering rock. The altitude at the well is 

 about 125 feet above Fox River Valley at Elgin, or 850 feet above tide. 



Sections of three deep wells were obtained in the township west of 



Elgin, as follows :

Mr. Russell, sec. 12, altitude 825 feet 100 



T. Read, sec. 32, altitude 925 feet 219 



Well in sec. 35, altitude 900 feet 146 



None of the wells enter rock, and in each well the drift is mainly a 

 blue till. In the last one an old soil was passed through at 131 to 137 feet. 



In the next township to the west, T. 41, R. 6 E., several flowing wells 

 have been obtained on a plain between morainic ridges at an altitude about 

 865 to 880 feet, and at depths ranging from 56 to 86 feet, as follows:

C. B. Godfrey, sec. 15, altitude 880 feet 72 



G.H.Brown, sec. 22, altitude 875 feet 64 



D. W. Pierce, sec. 27, altitude 875 feet 70 



E. E. Barry, sec. 27, altitude 865 feet 56 



S. R. Ellithorp, sec. 27, altitude 875 feet 86 



A well at John McDonough's, in sec, 26 of this township, 125 feet 

 in depth, strikes an old soil at 40 feet. This soil is probably referable to 

 the Peorian or post-Iowan interglacial stage. The altitude is not greatly 

 different from that of the flowing wells, yet a flow was not obtained. , 



A well at the mill in the village of Burlington, 165 feet in depth, is 

 in rock a few feet. A well at a hotel in the village reaches a depth of 

 100 feet and obtains water in gravel below blue till. In the vicinity of 

 Burlington several wells exceed 100 feet in depth. One in sec. 5 is 114 

 feet and another 99 feet. One in sec. 17 is 117 feet in depth.
