The most interesting features of this tab^le are 

 the results from plat 12, where there was only a very light 

 growth of soy beans in the corn. Kot only was the percen- 

 tage of the optimum moisture higher than on any of the 

 other plats, but was higher in the corn than in the ends. 

 These averages can not be due to any aberrent determinations 

 for an examination of the detailed data (Table "A" Appendix) 

 shows that for each determination the same differences 

 are shown. Some of these determinations were made before 

 any soy beans were above ground. This is the more inter- 

 esting on account of this being the highest plat o? the 

 whole experimental area. Had this been a heavier soil 

 there would be a possibility of a water coming to the sur- 

 face where the gorh was growing from higher ground, but 

 even under this circumstance the very slight difference 

 between the elevation of this plat and the level of the 

 land above would make such an explanation improbable. It 

 appears, therefore, to b^due to strong capillary action. 

 The protection against evaporation by the corn appears to 

 conserve more moisture than is transpired by the plants.
