754 THE ILLINOIS GLACIAL LOBE. 



of Altamont, on the divide between the Little Wabash and Kaskaskia, wells 

 enter rock at about 30 feet and obtain water at 40 or 50 feet. 



In the vicinity of Moccasin and Beecher wells occasionally enter rock 

 at 30 to 40 feet, but are usually obtained at 20 or 30 feet from drift beds 

 of sandy structure. 



In the vicinity of Effingham wells are obtained at 18 to 20 feet in 

 sandy beds below till. Rock is entered at 25 or 30 feet. The supply for 

 waterworks is pumped from Little Wabash River. 



In the vicinity of Edgewood and Mason, in the southern part of the 

 county, rock is usually entered at 20 to 25 feet, but most of the wells obtain 

 their supply from near the base of the drift. A coal boring near Edge- 

 wood is reported, in the Geology of Illinois, to have penetrated 59 feet of 

 drift. 



JASPER COUNTY. 

 GENERAL STATEMENT. 



Jasper County is situated east of Effingham, with Newton as the county 

 seat, and has an area of 506 square miles. The Embarras River runs south- 

 eastward through the central portion of the county. Its tributaries are 

 mainly on the northeast, leaving the western and southern portions of the 

 county outside its drainage basin and tributary to the Little Wabash. The 

 valley of the Embarras is nearly 2 miles in average width and has sandy 

 bottoms. The uplands in this county, as in the neighboring counties on the 

 north and west, are covered with a white clay, which absorbs rainfall very 

 slowly. 



The drift, like that of Effingham County, is composed mainly of till 

 of moderate depth, seldom more than 50 feet. Along the Embarras River, 

 however, the depth is greater and may exceed 100 feet. Tributaries of the 

 preglacial Embarras have been filled so completely that their courses can 

 scarcely be traced. The wells are usually obtained at depths of only 20 or 

 30 feet. But few records have been procured, the conditions for wells being 

 somewhat uniform throughout the county. 



INDIVIDUAL WELLS. 



Iii the vicinity of Newton wells are usually about 20 feet deep, and in 

 a few instances they reach rock at that depth. The waterworks supply is 

 pumped from the Embarras River.
