There is probably no other field in soil physics which is so devoid of reliable laboratory methods as that of percolation of water in soils. Indeed, it can probably safely be said that there is no method for studying the rate of percolation ,of water in soils which can be regarded reliable for comparative purposes. These statements are selfevident when it is considered that the results yielded by the present methods may vary in duplicate experiments from ~oo to ~,ooo% without apparent reason, and when every attempt is made to perform the duplicate experiments in an identical manner. Furthermore, even if the duplicate results agree, they may not bereally true for the different soils. Possibly there may never be worked out a laboratory percolation method for soils that will be absolutely satisfactory, due to the fact that the factors that come into play are so numerous and of such variable nature and are so exceedingly difficult to control. In the present paper there is .presented’a new method which would seem to possess many advantages over the old method and which appears to give quite satisfactory results.
