THE ILLINOIS GLACIAL LOBE. 



At Amboy shallow wells are obtained at 12 to 20 feet, many of which 

 enter the rock. At the waterworks the supply is obtained from an artesian 

 well 2,000 feet in depth. Water veins which overflow were struck at 390, 

 1,100, and 1,700 feet. The lower veins do not increase the head, but evi- 

 dently increase the quantity, for the upper flows could be readily lowered 

 by pumping, while the lower ones can not. 



The discussion of wells on the moraine which follows begins in the 

 northeast part of the county, from which point the moraine is followed 

 southwestward.
