GENERAL CONCLUSIONS. 
That Benton is well supplied with excellent clays for the manufac- 
ture of the common grades of stonew r are and pottery is a fact estab- 
lished by the experience of many years. The clays there used, 
however, have a much wider distribution throughout the southern 
and eastern parts of the county than seems to be suspected. They 
have been found at Bernard Fiste's place, west of Rhodonbaugh's 
pottery, while the great bed cut in Mrs. Butler's well in sec. 13, T. 2 S.,
