CAPILLARY MOVEMENT OF SOIL MOISTURE. 69 



in Table 47 and those immediately preceding show conclusively that 

 capillarity and gravity tend to move the soil moisture downward to 

 considerable depths and in about twice the quantity that the moisture 

 moves upward. Add to this factor copious irrigation and it is read- 

 ily seen how even capillarity can assist and does assist in the waste 

 of irrigation water by deep penetration. 



In none of the data presented just above has the original wet soil 

 contained a percentage of moisture differing much from that which 

 would be found in the field immediately following an irrigation. 



Sufficient tests have not been made to warrant a final conclusion as 

 to the ultimate importance of the deep penetration of moisture, by 

 capillarity, in conjunction with gravity.
