592 THE ILLINOIS GLACIAL LOBE. 



INDIVIDUAL WELLS. 



In the northwestern township of the county, sections of three deep 

 wells were obtained near Wayne, one of which in sec. 7, 105 feet, and one 

 in sec. 8, 150 feet, in depth, do not reach rock, but one in sec. 33 enters 

 rock at 162 feet. In the first two wells a large amount of sandy material 

 was penetrated, but the third well penetrated nothing but till. 



In the middle township of the north tier several wells have been sunk 

 near Roselle to a depth of 100 feet or more without entering rock. The 

 majority of them are mainly through till. 



In the northeast township several flowing wells have been obtained in 

 the vicinity of Itasca at shallow depths along a tributary of Salt Creek. 

 The depths are but 20 to 30 feet, and the water rises scarcely 5 feet above 

 the surface. There are also numerous shallow flowing wells along Salt 

 Creek between Salt Creek Station and Elmhurst. It should be noted that 

 this flowing-well district is adjacent to that of Cook County, discussed 

 above. The altitude is 75 feet or more lower than at Palatine, being 

 scarcely more than 650 feet along Salt Creek Valley, and about 690 feet 

 at Itasca. Neighboring portions of the Valparaiso morainic system on the 

 west rise fully 100 feet above the wells at Itasca, and it is probable that 

 this moraine constitutes the absorbing area. 



A well at Bensonville, about 2,000 feet in depth, penetrates 97 feet of 

 drift. No further data concerning the well were obtained. 



At Elmhurst records were obtained of two wells which strike rock at 

 70 and 98 feet respectively. Within a mile west of these wells a limestone 

 quarry is opened at a level only 15 or 20 feet below the well mouths. 

 About 3 miles south also a quarry is opened on the bluff of Salt Creek. 

 The public water supply is pumped from a spring about 3 miles distant 

 from the town. 1 



Along the valley of Salt Creek, south from Elmhurst, wells are in 

 places sunk to a depth of 50 feet, mainly through gravel. At the village 

 of Fullersburg, however, wells obtain their supply of water in gravel at a 

 depth of but 12 feet. 



At Hinsdale the public water supply is obtained from a well 864 feet 

 in depth. This is reported by the Manual of American Waterworks to 

 afford 1,000,000 gallons per day. The last edition of this manual reports a
