CORRELATIVES OF BLOOMINGTON MORAINIC SYSTEM. 105 



Benton County. — At Templeton, in Benton County, altitude 700 feet, W. J. Terapleton made 

 a boring many years ago to 300 feet without reaching the bottom of the drift; no flow of water 

 was obtained. 



A gas boring on Joseph Atkinson's farm, about 3 miles southwest of Oxford, penetrated 

 410 feet of drift to a coal-measure shale lying about 320 feet above sea level. The drift is 

 mainly blue till but contained beds of sand and gravel about 10 feet thick. 



A boring for coal made many years ago by W. J. and L. Templeton and others on the 

 Templeton farm 6 or 7 miles southwest of Oxford, in sec. 32, T. 24 N., R. 8 W., passed entirely 

 through the drift. W. J. Templeton gave from memory the following section: l

The black shale may not really be a shale, for the clay and sand which underlie it appear 

 to be drift, which may extend to the gray limestone at 372 feet. As the altitude at this boring 

 is probably not far from 750 feet, the top of the gray limestone lies at about 380 feet. 



At Talbot, about 5 miles west from the coal boring, altitude 764 feet, a well was sunk 

 to 310 feet without reaching the bottom of the drift. J. B. McKinney, of Fowler, who made 

 the boring, stated that the greater part of the drift is a dry sand, of yellowish color near the 

 top but assuming a bluish color in the lower portions. The only clay bed he recollected was 

 a few feet thick and about 60 feet from the surface. 



Mr. McKinney has made several other deep well borings in Benton County which have 

 not reached the bottom of the drift. One at Mr. Bennett's on the ridge passing west from 

 Parish Grove in the northeast part of sec. 33, T. 25 N., B. 9 W., is 264 feet deep, including 

 about 25 feet of till at the surface, overlying mainly a dry yellowish sand or sandy till. On 

 the same ridge, at Lawrence Bros.', sec. 4, T. 24 N., R. 9 W., the section of a well 240 feet deep 

 is similar. 



A well at the post office in Fowler, 160 feet deep, encountered no rock; it is in sandy till 

 or dry sand from the top nearly to the bottom, where water-bearing sand was struck. A natural- 

 gas boring one-fourth mile north of the depot and at about the same altitude (823 feet) struck 

 rock at a depth of 158 feet, mainly water-bearing sand. West of Fowler along Mud Creek 

 wells penetrate 50 to 75 feet of dry sand or sandy reddish till before obtaining a good supply 

 of water. Wells drilled by Mr. McKinney about 5 miles east of Fowler reach rock at comjDara- 

 tively slight depths. One hi the northwest part of sec. 15, T. 25 N., B. 7 W., at Wayne John- 

 son's, struck rock at 65 feet; the drift is entirely till, much of it yellowish. Another well in 

 the northwest part of sec. 10 of the same township struck rock at 72 feet; the drift is till except 

 about 5 feet of gravel at the bottom. 



A well 185 feet deep, on the farm of Samuel Davis just east of Boswell, struck no rock. 



In Ambia borings have been made to 100 feet, striking rock.
