The capillary rise of water in these soils was as fol-

As is always the case, the rise is most rapid immedi- 

 ately after the soil is placed in contact with the water 

 and the rate of rise decreases progressively as the limit 

 is reached. The more coarse the texture of the material, 

 the more quickly is the limit of rise attained. 



These figures are shown in the following curves: (1) 

 For the first twelve hours; (2) for the full period.
