Concerning the moisture of the soil the results of the most recent experiments differ. Ramann, in 1895, published a se- ries of results which indicated that the soil of the forest may be even drier than that of the neighboring open land. This view he finds strengthened by experimicnts made in small dearings within the forest, where he finds the sdl of the sunny side of the clearing and that of the old forest itself decidedly drier than the soil of the shaded part oi the dear- ii^, thou^ h% also finds the soil under a young bush cover more moist than that under old timber. Whether a forest cover aids in the accumulation of ground water by imi^rovii^ the permeability of the soil was made the object of an e]q>erinMnt by Wollny, in a series of incondusive sBiall pot experiments which led this investigator to the ques- tioaa^e remit that bare land was more condudve to percola- tion dnn ground covered dther by grass or trees. This would sorely be true only if the bare ground, as in the experi- ments, is kept in an artificial, not natural, condition. Attempts to deduce the influence of forest on waterflow fr(Mn whoksale measurements and observations have been made in this country by Vermeule, of New Jersey (see Proceedi
