Experiments in 1915. — The corn was followed by rye which was 

 sown in section B on October 22, 1914. The 6,600-volt treatment 

 alternating charge was started November 5 and maintained continu- 

 ously till June 24, 1915. This year at time of harvest each plat 

 (treated and control) was divided into eastern and western halves, 

 and each section was weighed separately to show any inequalities in 

 soil conditions. 



The yields recorded at harvest showed a lack of uniformity in the 

 plats, but gave no evidence of a sensible increase in yield due to the 

 electrical treatment. The results are shown in Table 12.

Experiments in 1916. — In order to measure the relative yielding 

 power of the two plats (treated and control) under normal condi- 

 tions wheat was again sown in the fall of 1915 and allowed to mature 

 the following summer without electrical treatment of either plat. 

 Table 13 shows the figures recorded at harvest, the north plat being 

 the treated plat of the three preceding years.
