WELLS OF KENDALL COUNTY, ILLINOIS. 647 



INDIVIDUAL WELLS. 



At Morris the public water supply is obtained from artesian wells 

 about 600 feet in depth which terminate in the St. Peter sandstone. The 

 head is sufficient to raise the water a few feet above the surface. Shallow 

 wells are obtained in the vicinity of this city, at depths of 14 to 30 feet, 

 either in gravel or in sandy shale of the Coal Measures. 



At Minooka a boring was sunk to a depth of 2,100 feet, which terminated 

 in the Potsdam sandstone. A very strong water vein was struck at about 

 1,985 feet, with sufficient head to rise 46 feet above the surface, or 660 feet 

 above tide. Although situated on the crest of the ridge, wells are obtained 

 in this village at depths of 30 or 40 feet. 



At Carbon Hill the public water supply is from an artesian well 1,900 

 feet in depth, from which water flows direct through the mains. 1 



At Coal City wells are usually obtained at about 12 feet in the sand 

 which covers that portion of the county. The waterworks are used for fire 

 protection only. 1 



At Braceville wells are found at the bottom of the sand and also beneath 

 the till at depths of 30 or 40 feet. Rock is entered at Braceville at about 

 45 feet. 



At Gardner wells are usually obtained from gravel or sand below till 

 at 40 or 50 feet. Coal shafts enter rock at about 60 feet. Mr. Thomas 

 Cumming, of Gardner, one of the State mine inspectors, reports that water 

 veins of excellent quality are found at several horizons in the Coal Measures 

 in the vicinity of the villages just mentioned. 3 



At Mazon wells are ordinarily obtained at depths of 30 or 40 feet, but 

 several deep wells have been made on farms in that vicinity which do not 

 reach rock at a depth of 100 feet. The drift is mainly a blue till. 



At Verona, and over an area of several square miles in the vicinity of 

 that village, sandstone is usually entered at about 75 feet.
