Brown (1936, p 18) summarized the information up to 1936 on the geography and classification of the prairie loess-derived soils of southeastern Iowa. The Tama and Grundy were the major series recognized. Field studies since 1942 indicated there was a need to revise the concept of these series. The present paper presents some data on selected profiles formerly classed with these series
