YT. 10 N., R. 3 W., at Mr. Whitsell’s. Surface elevation, 720 feet. Depth, 
12 feet. Under a shallow surface soil occurs a blue clay which contains 
very fine, angular sand grains. These grains are invisible to the eye, 
though they may be felt when the dry material is rubbed between the finger 
and thumb. This very fine sandy clay is very tough, tenacious, and 
slightly sticky when wet, and of a distinct blue color. On exposure to the 
air it takes on a brownish-grey hue. When dry it is an ash color. Ap- 
plicaton of muriatic acid shows that it is highly charged with calcium 
carbonate. (This detailed description is given because this material is 
often encountered in the lower parts of wells. Hereafter it will be desig- 
nated as blue clay. It will be further discussed iater. )
