Capillary Movements of Soil Moisture. 171 



Table showing the translocation of soil moisture due to wetting 

 the surface. 



The amount of water applied to the surface in this ex- 

 periment was 2 Ibs. per sq. ft. but when samples of soil 

 were taken 26 hours later there had been an increase of 

 3.072 Ibs. in the surface foot and a loss of 1.724 Ibs. from 

 the second and third feet. Observation showed that a tray 

 of soil, on a pair of scales at the place, lost, by evapora- 

 tion during the same time, .428 Ibs. per sq. ft. ; and, as- 

 suming that the field soil lost water at the same rate, makes 

 the water to be accounted for 



8.072+ .428 = 3.51b3., 



while the total loss from the lower two feet plus the water 

 added was 



2 + 1.721 = 3. 724 Ibs. 



an amount as nearly equal to the 3.5 Ibs. as could be ex- 

 pected. 



In another trial, adding 1.33 Ibs. of water to the sur- 

 face produced the gain, by translocation upward into the 

 upper four feet, shown in the next table.
