WELLS OF SCOTT COUNTY, ILLINOIS. 721 



At Time the village well has a depth of 70 feet. For a distance of 50 

 feet it is through a clay of brown color carrying few pebbles. The remain- 

 der is through a blue clay of the consistency of putty. Ravines in that 

 vicinity show about 20 feet of loess, beneath which is a slightly pebbly 

 brown clay. A well at J. E. Dinsmore's, 2 miles south of Time, reached a 

 depth of 60 feet, mainly through pebbly clay, and did not strike rock. Mr. 

 Dinsmore made another well in a ravine at an elevation about 40 feet 

 below the one at his residence which passed through a black muck below 

 brown clay at a depth of 40 to 45 feet and entered a red clay similar to the 

 residuary cldj formed from limestone in that vicinity It had not struck 

 solid rock at a depth of 50 feet. 



At Pittsfield the public water supply is from a well 2,200 feet in depth, 

 which is used for fire protection and street sprinkling only. Private wells 

 are obtained at moderate depth in the rock, seldom more than 50 feet. On 

 the drift ridges west from Pittsfield wells reach depths of 30 to 50 feet 

 without entering rock, obtaining their water from sandy drift associated 

 with the clay. 



At Nebo, in the valley of Bay Creek, wells are obtained at only 15 or 

 20 feet in sandy beds at about the level of the creek. On the'borderino- 

 uplands wells are sunk into rock to depths of 50 or even 100 feet. 



SCOTT COUNTY. 

 GENERAL STATEMENT. 



Scott County has its west border on the Illinois River, opposite Pike 

 County. Its area is but 250 square miles, and Winchester is the county 

 seat. It is drained westward by tributaries of the Illinois, of which the 

 principal ones are Mauvaise Terre and Big Sandy creeks. The Illinois 

 bottoms occupy a strip about 3 miles in average width along the west 

 border of the county. The uplands have a coating of loess, which is 25 to 

 50 feet in thickness on the border of the Illinois, but decreases eastward to 

 scarcely more than 10 feet at the east line of the county. The drainao-e 

 lines, together with the loess, dispose of the rainfall rapidly. In the Illinois 

 River bottoms the sand is in places so light as to be barren in seasons of 

 drought. 



The drift in portions of the county is very thick, there being along the 

 Illinois bluffs wide stretches in which no rock is exposed, though the bluffs
