The season was exceptionally dry and the soil light, so that the 

 conditions were not favourable to the discharge. 



During the year 1909 some trials in electro-culture, of an ex- 

 ceptionally interesting character, were conducted at Dahlem, in 

 Germany. 



The experimental ground was divided into four plots ; a certain 

 number of plants were adopted as standards, among them being 

 spinach, radish, cabbage and lettuce* These were grown under 

 normal conditions. The same variety of plants in another plot 

 were exposed to intensified atmospheric electricity by means of 

 currents on overhead wires. A third group was treated with 

 high tension electricity, while a fourth was covered with a wire 

 cage arranged so as to exclude all the natural electricity in the 

 atmosphere. The following table gives the results obtained from 

 each of the plots.
