A technique for direct measurement of hydraulic head in rapidly changing systems was applied to the infiltration of water into artificially packed columns of dry soil including three California soils and a sample of silica flour. Results indicate that the transmitting zone in each soil was a region of relatively uniform hydraulic gradient which was greater than unity but decreased with time and might approach unity as a limit. At corresponding stages of infiltration, the magnitudes of the gradients in the transmitting zones differed for the various materials.
