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.
