BUTLER COUNTY. 393 
this same south-casterly direction has been shown to be that in which 
the glaciers advunced in this portion of the State. 
Some of these streams, as, for example, Seven Mile Creek and its trib- 
utaries, run largely on rocky beds, and thus show themselves to be of 
comparatively recent date. Others again, as Twin Creek and Indian 
Creek, agree with the deeper valleys of the county in having the rock 
altogether concealed by heavy alluvial deposits, and thus lay claim toa 
longer history. 
The highest land of the county is not more than 650 feet above the 
Ohio River at Cincinnati. The highest land measured is two miles west 
of Jacksonburgh, Wayne township, on the farm of Col. Phares. Its 
elevation by barometer is 642 feet above the base above named. Locke 
gives the elevation of a point of Cliff Limestone that barely enters the 
county on the north line of Milford township as 601 feet. Two miles 
due west of Oxford, on the Fairfield turnpike, an elevation, determined 
by the level, occurs of 610 feet above the Ohio River at Cincinnati. The 
elevations of a few of the prominent points in the county are appended, 
as obtained from canal and railroad and turnpike surveys. For several 
of the elevations here recorded, I am under obligations to Prof. R. W. Mc- 
Farland, of the Ohio Agricultural and Mechanical College :

The lowest ground in the county is to be found on its southern bound- 
ary, in the Miami valley. Its approximate elevation above the base 
already named is fifty feet. 
The principal areas of the allyvial lands and uplands of the county, 
as they are distinguished from each other, are represented in the accom- 
panying map. The former division embraces the valleys both ancient 
and modern—the eroded regions from which the rocks have been carried 
away to a depth at least below existing drainage courses. These areas
