and 22a. These points as in the case of those for op- 

 timum moisture content were all selected before the cal- 

 culations were made. On the whole the results are usually 

 below those found in the corn at a time when most of the 

 plats were suffering for lack of moisture. Plat 10, 

 however, was perhaps not suffering as much as the others, 

 if indeed it was suffering at all, since caf)illarlty appears 

 to have been stronger in the soils of the coarser plats , 

 The differences between the two columns are greatest in 

 plats 1 and 22. The method appears to be fairly dependable 

 for the determination of the relative drought limit 

 in these soils, but the results were not as conclusive as 

 those for the optimijm moisture. However, the greater 

 variation in the resraifets for the "drought limit" may have 

 been due as much to variations from the drought limit in 

 the corn as in the results from the cylinders of soil. 



The differences in the rate of aapillarity 

 together with other factors would make it impossible to 

 secure results in the field which were more than approxi- 

 mations . 



While these two results are below the drought lim- 

 it for corn they are above that for som.e other plants. It 

 should be remembered that this drought limit is oonsiderablgr 

 below the point where plants can make a vigorous growth. 

 Perhaps if capillary water is excluded, the water available
