WELLS OF LIVINGSTON COUNTY, ILLINOIS. 



(367 



vation, struck rock at 221 feet. 1 The latter boring had hard till in the 

 lower part of the drift, while the former passed through a "dirt bed with 

 wood" just before entering rock. 



In the vicinity of Risk and Strawn, in the south part of the county, 

 there is about 90 feet of drift as determined by coal borings, but wells are 

 usually obtained at 50 feet or less in sand below till. 



The public supply at Flanagan is reported by the Manual of American 

 Waterworks to be from an artesian well, but no data are given as to depth 

 or head. 



Coal borings made at the villages of Cullom, Saunemin, and Campus, 

 in the east part of the county, penetrate 171, 162, and 125 feet of drift, 

 respectively, but wells at these villages are obtained at moderate depths, 

 seldom exceeding 40 feet in sand or gravel below till. The Manual of 

 American Waterworks reports that Campus obtains its public water supply 

 from a driven well. 



In some places water is very difficult to obtain at moderate depths; 

 thus, at the village of Griswold, several borings have been sunk to a depth 

 of 75 feet without obtaining strong wells. 



Outside the villages just discussed only a few records of wells have 

 been obtained, and these include the deepest of which the writer has 

 obtained information :
