38 ELECTRICITY IN AGRICULTURE 
The machine was kept in motion from 6 to 7 a.m. till 
9 to 10 a.m.,and from 4 to 5pm.to8tog p.m. Incloudy 
and cold weather, which occurred very seldom, the machine 
was kept moving a longer time, sometimes even all night.

From the middle of June the windows were kept open 
during the night in order to lessen the warmth. Watering 
was done every day in measured quantities. For the first 
two weeks Section II., or the section in which the current 
went from the plants to the wire net, showed the highest 
development; but from this time Section I., where the 
current went in the opposite direction, began to take the 
ascendency, and kept it till August 13th, when the experi- 
ments ceased. This refers only to the barley, oats and wheat. 
On July 1oth appeared the first ear of oats in Section IIL, 
on July 14th in Section II., and on July 16th in Section I. 
On July 23rd the brush of a barley-ear began to appear 
in Section I., and on July 25th in Section II. The wheat 
could not, however, be brought to form ears. 
This proved generally that these kinds of cereal could 
not be brought to a normal condition of development in 
the prevailing high temperature, and so the experiments 
ceased, as I have said, on August 13th. 
But the development of the strawberry plants went on 
normally, except in Section I., where the plant died, pro- 
bably from the strong effect of the current. In Sections IT. 
and III. the commencement of the flowerings, of which the 
plants in Section II.showed a powerful growth, wereremoved. 
At the end of the experiments the cereals showed, at an 
exact estimation, in 
Section I. 60 per cent. more development than in Section IV.
