I an earlier paper (3), the variability in chemical composition of the soil separates and of some of their fractions was dealt with. Profiles of two soil types were studied; one, Montalto silt loam formed on parent material of Triassic basalt in the Appalachian physiographic-geologic province, and the other, Colts Neck loam formed on parent material of unconsolidated clays, silts, sands, and gravels of Cretaceous greensand marl origin in the Coastal Plain physiographic-geologic province. In the paper referred to a more detailed description of the soils under study and of the methods of analyzing the separates and their fractions has been given. From the data on the total chemical analyses some conclusions on the history and development of the soils have been presented. In the discussion following, the deductions, based on the total chemical analyses, are scrutinized in the light of the physicochemical behavior of the exchange complex of the soils under study.
