south of this village, in sec. 11. T. 26, R. 12 W., a well 156 feet in depth 

 entered rock near the bottom, and struck a bed of coal. Two other borings 

 Located in the north part of T. 25. R. 11 W., enter rock and strike coal at 

 only 60 feet. Several other wells in that locality reach a depth of 160 feet 

 without entering rock. They penetrate about 80 feet of soft till, beneath 

 which is a hard till, in which little sand is found at less than 160 feet from 

 the surface. 



Along- Sugar Creek Yallev. north of Milford, three wells were noted 

 which strike an inflammable gas in sand below till at a depth of 40 feet. In 

 the vicinity of Milford wells are usually obtained at depths of 40 to 60 feet. 

 and water does not rise usually within less than 25 feet of the surface, or to

West from Milford.. for 6 or 8 miles, several wells have been sunk to 

 depths of 100 to 110 feet, which obtain water in sand below the blue till. 

 Its head is 20 feet or more below the surface. 



In the southeast part of Iroquois County a black soil has been found 

 in a few wells at about 160 feet. These wells penetrate 90 or 100 feet of 

 soft till and 50 feet or more of hard till before entering the soil. 



At Wellington, wells are often obtained at a depth of 70 feet, which 

 have a head about 20 feet below the surface, or 680 feet above tide. They 

 are said to enter a hard till in the lower 10 or 15 feet. 



At Clayton flowing wells are obtained at a depth of 60 or 70 feet and 

 also at about 100 feet. The deeper ones penetrate an old soil near the 

 bottom. The head at these wells is about 675 feet above tide. Four miles 

 south of Clayton, in sec. 27. T. 24. R. 13 W., two flowing wells have been 

 obtained, one at 50 feet, the other at 80 feet, whose head is nearly 700 feet
