It is clear from fig. 2 that variations in the water but that the magnitude and rate of variation were no precipitation. The distribution of the rainfall was impo frequency bore relation to rates of percolation and eva experimental field, surface run-off was negligible. Dur capillary fringe extended to the surface so that evapor by plant life constituted a most important factor in th peratures were high and wind movements brisk and the other hand, percolation to the water table approxim sands had been saturated after repeated heavy rains favorable. In late winter and early spring a large pro water table.
