In Ohio certain differences between soils in the glacial limestone region and those of similar texture in the glacial sandstone and shale region are noticeable even to the casual observer. Many of the former have sticky, plastic B horizons, while the latter tend to have B horizons that are more brittle, less plastic, and will crush rather than give way gradually when pressure is applied. Taylor (3) has noted the occurrence of a hard layer in several soils of New York and Pennsylvania. This property of hardness in one or more horizons is also observed in the soils of northeastern Ohio (glacial sandstone and shale material) but decreases as the limestone region is approached. It is possible that such differences in the properties of soils may be correlated with:
