Extract

The attentiou of all scientists in Egypt has been more and more closely directed to the problems of Soil-water since about the year 1907. In the first instance this attention was of necessity devoted to the water-logged layer of the soil and sub-soil, to the fluctuations of this layer in time and in space, and to its effects on the cotton plant.
