The results of tests so made confirm the idea which was given 

 by Table 2, namely, that the relation of the moisture equivalent, as 

 determined by a force of 100-gravity, to the wilting coefficient, may 

 depend a great deal on the type of soil. To make the reason for 

 this clearer, the data of Table 2 have been further grouped in Table 



4, while diagram 6 assists in visualizing the relations. Data for 

 other types of soil have also been introduced. In the case of the 

 sands and the prairie clay, the conditions under which the wilting 

 coefficients were determined were perhaps conducive to slightly 

 lower values than in the other groups. This, however, will affect 

 the comparisons of wilting coefficients with capillary moisture and 

 moisture equivalents, about equally.
