WELLS OF MACOUPIN COUNTY, ILLINOIS. 743 



INDIVIDUAL WELLS. 



At Virden, in the north part of the county, wells are usually obtained 

 at 15 to 25 feet from sandstone, the drift being very thin in the vicinity of 

 that village. The best wells are estimated to yield 50 barrels per day, but 

 usually a well will afford only a small fraction of that amount. During 

 the drought of 1894-95 so many of the wells became dry that fears of a 

 water famine arose. 



At Modesto, also near the north border of the county, rock is entered 

 at 25 or 30 feet, but wells are usually obtained near the base of the drift. 



In the vicinity of Scottville, in the northwest part of the county, the 

 drift is about 50 feet in depth and usually affords abundance of water for 



wells. 



At Girard and Nilwood, in the northeastern part of the county, the 

 coal shafts enter rock at about 70 feet. Wells are usually obtained from 

 thin beds of sand at about 20 feet. The drift is mainly a blue till. 



At Carlinville the public water supply is pumped from Macoupin 

 Creek. A coal shaft enters rock at about 75 feet. In the Geology of 

 Illinois an instance of the penetration of a thick sheet of drift near this 

 city is noted. A boring in Macoupin Creek Valley, made by T. L. Loomis, 

 reached a depth of 160 feet without entering rock. It was mainly through 



blue till. 



At Medora a coal boring is reported in the Geology of Illinois to have 



the following section :

In the vicinity of Brighton, in the southwest part of the county, rock 

 is struck at about 30 feet, but wells are usually found in the drift. 



At Bunker Hill wells are usually obtained at 20 to 30 feet in sand 

 below till. They are estimated to have an average daily yield of about 5 

 barrels. A coal shaft in this village is reported in the Geology of Illinois 

 to enter rock at 28 leet. 



At Staunton the public water supply is obtained by impounding water
