IN NATURE of August 6, 1908, Dr. Russell refers, in his note on soil moisture, to some information on this subject which I published in Memoir No. 6 (Chemical Series) of the Department of Agriculture in India, and says, “Dr. Leather argues that water moves upwards from a limited depth only. … The results are equally well explained on the supposition that the upward movement takes place at all depths, since the amount of water present in a particular layer depends on the respective rates at which water is gained from below and lost to the upper layers.”
