26 ELECTRICITY IN AGRICULTURE 
the wire net and the plants. This resistance is, in general, 
greater in the day, the air being drier, than at night, when 
the air is more humid. The electrical air-current which 
goes from the wire net through the plant is, therefore, 
different during the day than during the night. The plants 
show in their life cycle essential inequalities during the 
day and the night. It is for this reason that the electrical 
treatment was in 1900 restricted to the night hours.

Oats. 
The oat fields showed this year such great inequality 
that no sure results were to be expected from them. They 
were situated a little higher on the squares where the 
carrots were planted in 1899. This inequality was due to an 
old ditch, which some ten years previously had been filled. 
This ditch went through two of the experimental squares, 
and lowered their fertility in such a remarkable way that 
comparing them with the other squares with a prospect of 
sure results was out of the question. My opinion is, how- 
ever, as I had an opportunity of following the whole 
development during the summer, that the electricity exer- 
cised so great an influence that the effect of it was about 
the same as on the barley above. |
