AIDE from the pedological significance attached to the minerals occurring in soil colloids, knowledge of these minerals is important in relation to chemical properties. There are differences in the cation and anion exchange capacities and in the degree of dissociation of exchangeable cations and anion activity. These studies are a continuation of previous investigations of soils from the southeastern United States by Russell Coleman and Jackson (5) . Soils of the Cecil series and many of the other Red and Yellow Podsolic soils are primarily kaolinitic (1, 5, 7, 12). Coleman and Jackson (5) , however, found that several soils on the Coastal Plain of Alabama and Mississippi contained large proportions of montmorillonite and hydrous mica. Montmorillonite has been shown to predominate also in a Sharkey (Miss.), an Iredell (N. C), and a Houston black clay (Tex.) (7). Alexander, et al. (2) found gibbsite to be present in some southeastern soils derived from norites, amphibolites, and muscovite-biotite schists.
