WELLS OF IEOQUOIS COUNTY, ILLINOIS. 657 



feet without reaching- rock. Wood is found occasionally near the bottom. 

 Water rises within 15 feet of surface or to about 630 feet above tide. Three 

 miles northwest of this village, in sec. 26, T. 28, R. 13 W., a well penetrates 

 till sheets of different hardness. The upper 45 feet is a soft till, the 

 remainder a hard till. The bed of sand at bottom furnishes water which 

 rises within 3 feet of the surface. In the adjoining section on the south 

 (sec. 35) a well 156 feet in depth does not reach rock. Water rises just to 

 the surface. In sec. 29 of this township a well penetrated an old soil near 

 the base of the drift at a depth of about 95 feet. Wells in that vicinity 

 enter shale at about 100 feet and limestone at about 160 feet. 



In the north part of the county, near Chebanse, rock is entered at 80 to 

 100 feet. About 3 miles east of the village on the farm of O. Sykes, and 

 also on neighboring farms, wells were noted in which beds of peat 20 feet 

 in thickness were found near the base of the drift at depths of 60 to 80 feet. 



In the vicinity of Ashkum wells usually enter rock at about 80 feet, 

 though one half a mile west of the village reached a depth of 146 feet 

 before striking rock. There is usually a soft till about 50 feet, beneath 

 wlhch is a harder till, associated in places with sand beds. The water level 

 from wells obtained in the lower part of the drift and upper part of the rock 

 is 10 to 20 feet below the surface, or about 640 feet above tide. Along the 

 border of Langum Creek Valley, in the vicinity of Ashkum, wells enter 

 limestone at 60 to 90 feet. In some cases they obtain water in sand below 

 till at 40 to 60 feet. The water usually rises within 5 or 10 feet of the 

 surface. A well at Mr. Mayo's, about 5 miles northwest of Ashkum, pene- 

 trated 120 feet of drift containing a log near the bottom, and terminated in 

 shale at 167 feet. AVater stands within 4 feet of the surface, the altitude 

 being slightly lower than at Ashkum. About 3 miles west from this well 

 the records of three wells were obtained which obtain water in limestone 

 at 60 to 68 feet. The head is sufficient to bring the water barely to the 

 surface. 



In the vicinity of Prairie Creek, southeast from Ashkurn, a few flowing 

 wells have been obtained from the drift at depths of 75 feet or less. 



At Danforth wells from the drift 100 feet in depth have a head about 

 7 feet below the surface or about 640 feet above tide. The last edition of 

 the Manual of American Waterworks reports a deep well in progress, but
