WELLS OF RANDOLPH COUNTY, ILLINOIS. 769 



was blue till. A well at J. Porch's, 35 feet in depth, is mainly through till, 

 the lower part being of blue color. 



A well on a knoll in see, 10, T. 4 S., R. 6 W., obtains water in gravel 

 at 25 feet. A well near the base of the knoll at 15 feet lower elevation 

 enters rock at 20 feet. 



At Coulterville wells enter shale at 20 to 25 feet and obtain water at 

 about 30 feet. A boring 1,117 feet in depth obtained brackish water from 

 the Chester sandstone, of which no use is made at present. A complete 

 record of strata penetrated is published in the Final Report of Illinois Board 

 of World's Fair Commissioners. 



At Sparta the wells are seldom more than 30 feet in depth and obtain 

 their supply from the drift. A boring 480 feet in depth made at this village 

 furnishes water suitable for laundry purposes, but not for drinking. Several 

 deep borings at this village obtain a supply of gas from the base of the 

 Chester limestone at 840 to 864 feet, The drift at these borings rano-es 

 from 34 feet to 116 feet, the thickest being on the lowest ground (J. M. 

 Nickles). 



A coal shaft near Eden Station penetrated a complicated series of drift 

 beds, a section of which appears on page 117 

 , At Steeleville wells are usually obtained at 18 to 22 feet from sandy 



beds in the drift. An artesian well 312 feet in depth enters rock at 60 feet 

 and furnishes water of good quality for drinking. The well overflows at 

 the rate of about 2 gallons per minute. A complete section of the strata 

 penetrated by this well is published by Professor Nickles in the report 

 of the Illinois Board of World's Fair Commissioners. 



Wells along the drift ridge both north and south from Steeleville have 

 been sunk to depths of 40 or 50 feet without entering rock. They are 

 mainly through till. 



At Shiloh Hill, which stands on the outer border of the belt of ridged 

 drift, wells have been sunk to a depth of 35 feet, in some cases penetrating 

 wood near the bottom below till. 



At Wine Hill, on a prominent point in the southern part of the county, 

 a well is reported to have been sunk to a depth of 36 feet without entering 

 rock, but rock is exposed in that vicinity at depths of 20 to 30 feet.
