Capillary Movements of Soil Moisture. 169 



diameter and 12 inches long, standing in one inch of wa- 

 ter and possessing the undisturbed field texture. The 

 cylinders stood in a saturated atmosphere and the amount 

 of water absorbed was determined by weighing every third 

 dav, the samples being the same ones used in (158) and 

 (159). 



Table showing the mean daily absorption of capillary water 

 by undisturbed field so/7. Cylinders 6 inches in diameter, 

 U inches long, standing 11 inches out of water. 



-b'rom this table it is seen that the amount oi water 

 absorbed during the first three days was only at the mean 

 daily rate of 4.16, 4.13, 3.20, 4.5 and 3.58 Ibs. respective- 

 ly; after the first period the rate of rise was much less 

 rapid and did not equal the rate at which an almost iden- 

 tical soil (196) raised water through 4 feet as measured 

 by the daily evaporation; and yet the daily rise of water 

 of .91 and .90 Ibs. per sq. ft, would have been greater 

 had the evaporation only been more rapid. In the case 

 of the sand of (195) the water was lifted by capillarity at 

 the enormous rate of 228.0 Ibs. per sq. ft. in 24 hours 

 while the sandy loam of (194), placed under the conditions 

 of (195), using the same piece of apparatus, lifted water 

 at the rate of 20.62 Ibs. per sq. ft. in the same 24 hours.
