PLEISTOCENE OF INDIANA AND MICHIGAN. 



In the well 200 yards farther east the driller recognized three series of beds, each con- 

 sisting of till, sand, and gravel, in the order named. The till in the lower series is harder and 

 drier than that in the middle and upper. The drillers were unable to give the thickness of the 

 individual beds.

The drift in the well a mile southwest of Kempton is said by the secretary of the Frankfort 

 Gas Co. to be mainly blue till, but no accurate record was kept. 



Clinton County. — At Scircleville, in Clinton County, a gas boring, altitude 930 feet, pene- 

 trated 296 feet of drift. The upper 150 feet is mainly till. Below this thin beds of sand 

 alternate with till for about 30 feet, beneath which is 115 feet of cemented gravel. 



At Mr. Lee's, 4 miles east of Frankfort, a gas well at an altitude of about 900 feet pene- 

 trated about 300 feet of drift. A boring south of Frankfort, altitude about 860 feet, did not 

 reach the bottom of the drift at 297 feet. Several wells along Prairie Creek in Frankfort flow 

 from a bed of sand beneath a heavy bed of blue till, at a depth of about 80 feet. A well in the 

 northeast part of Frankfort, altitude about 850 feet, has the following section:

Tippecanoe County. — At Dayton, in Tippecanoe County, a boring in the valley of South 

 Wildcat Creek, the surface of which is 50 feet or more below the level of the railway station, 

 or about 600 feet above sea level, penetrated 160 feet of drift. The rock surface stands more 

 than 200 feet higher at Buck Creek station, in the northern part of the county, for rock is 

 struck there about 20 feet below the level of the depot, or 653 feet above sea level. 



At the courthouse in Lafayette, in the valley of Wabash River, an artesian well penetrated 

 170 feet of drift, the rock surface being but 380 feet above sea level. WiUiam McKay, who 

 superintended the boring, gives the following section:
