Pg. 29. "Dekalb limestone" of Iowa Geol. Survey, defined by Bain, is synonym of Winterset [an older limestone than Westerville], and should be discontinued because latter has priority. The Westerville limestone defined by Bain, is "Drum limestone" of Kansas City section.

Pg. 40. †DeKalb limestone. In Oct. 1932, R.C. Moore, G.E. Condra, and F.C. Greene traced so-called Drum limestone of Kansas City area to Winterset, Iowa, and determined that type DeKalb is Winterset limestone. As Winterset has priority, the term DeKalb must be dropped.
