 "The differenees in th© psreent&ge of moistift'e in these 

 plats are due to the eharaeter and perhaps the topography 

 of the soil, the lower percentages being on t,he aandier and 

 higher ground. In general the lower th© pere^nt^St ©^ 

 moisture, the larger the yield of maize. It is extrsiaely 

 unfortumete that the proportion of water soluble nitrogen 

 was not determined by these po-ats." While the aaount of 

 soluble nitrogen is suggested as an explanation of the 

 difference in yield, the relative coarseness of the soil of 

 plats producing the best yields, woiild in the light of 

 results obtained in the laboratory, and observed in the 

 Florida soils, indicate a higher c&piliary power. 



The siae of soil particles whieh havo the greatest 

 capillary power appears to be larger than is usually supposed.
