During the course of certain laboratory experiments on soil permeability to water it was found that the permeability of the soil column showed a marked decrease with continuation of the downward flow. Similar observations have been made previously (2, 4, 5, 6). With the exception of the excellent quantitative work by Harris (4) upon a single Utah soil, no data appear to have been presented indicating the magnitude of the change in relation to duration or magnitude of flow, and there has been but little investigation of its cause. Accordingly this experiment was planned to determine whether decreased water permeability may be expected to accompany the long-continued leaching of a variety of soils of unlike nature and also to measure the extent of the changes observed.
