THE VALPARAISO MORAINIG SYSTEM. 361 



Van Dusen, 40 feet in depth, penetrates a sticky blue clay almost pebble- 

 less and obtains water from a gravel. There are three flowing wells in sec. 

 34, Watson Township, none of them exceeding- 50 feet in depth, of which 

 the major part of the section was gray till. A flowing well near the south 

 line of Watson Township, 1 £ miles east of Abronia, on the farm of Martin 

 Hewer, penetrates a blue-gray till 87 feet and obtains its flow from a bed 

 of sand. The source of supply for these wells is probably in the neigh- 

 boring high parts of the Valparaiso morainic system. 



On a very elevated portion of the moraine in sec. 9 of the same town- 

 ship (T. 2 N., R. 12 W.), where the elevation is about 150 feet above the 

 boring at Mr. Palmer's, a well penetrated dry sand and gravel to a depth of 

 125 feet, and beneath this 25 feet of cemented gravel interbedded with 

 reddish clayey gravel. On this elevated tract several wells 80 to 120 feet 

 in depth are largely in assorted material. They contain thin beds of bluish 

 clay alternating with thick beds of sand and gravel. 



North of this elevated tract, on the till plain which sweeps around its 

 western end, there are several flowing wells. They are in the southern part 

 of Hopkins and western part of Wayland townships (T. 3 N., R. 12 W. and 

 T. 3 N., R. 11 W.). Their surface elevation is about 100 feet lower than the 

 general elevation of the bordering moraine, and 150 to 175 feet lower than 

 the highest points. They range in depth from 40 to 165 feet. They are 

 mainly through blue till, beneath which is a hard gray clay. 



A well near Ohio Corners, about 2 miles north of Hopkins, penetrates 

 the following beds:

At the bottom of this clay solid rock about a foot in thickness was 

 found and below this salt water was struck. If no mistake was made by 

 the well borer in identifying "No. 4" as limestone, the rock here attains an 

 elevation of at least 650 feet above tide, an unusual elevation for this latitude 

 so near the east shore of Lake Michigan. Perhaps "No. 5" is a shale.
