tinder Various Electrical Conditions . 137 
Strawberries at Evesham have on several occasions shown marked 
acceleration. Thus in 1907 : 
First complete picking, June 28th, Electrified 56 lb. 
„ „ Control 33 lb. 
The size of the area electrified was only 56 per cent, of the size of the 
control area, so that this relative yield, if maintained, would mean an 
increase of about 200 per cent, as the result of electrification ; but the effect 
was mainly acceleration, and the final difference in yield between the two 
plots represented an increase of only 25 per cent. 
In 1908 the results with strawberries were as follows: 
Pickings, June 20th and 22nd. (Areas as in 1907.) 
Electrified 1,318 lb. 
Control 1,876 lb. 
This yield maintained would represent an increase of about 25 per cent, 
but the total pickings actually showed 9 per cent, less strawberries from 
the electrified area. 
Similarly with tomatoes at Evesham in 1908 ; the early pickings up till 
September 24, when compared with the total yield, show marked accelera- 
tion in ripening under electrification.

From these figures it is evident that the yield from the control plants in 
time approaches that from the electrified. The reasons for expressing the 
yields from the electrified area in two sections, A and B , is that whilst 
plot A was, as far as could be ascertained, exactly comparable with the 
control, the plot B was slightly favoured as regards aspect and also 
irrigation. 
In the Bitton experiments in 1908, where cucumbers under glass were 
grown under electrification, the yields in the first month seemed to indicate 
distinct acceleration, and are therefore given in full. They correspond to 
the time before the plants had grown up behind the supporting wires, which 
later effectually screened them from the discharge. The pickings were 
usually made three times a week ; the dates are given in the top line of the 
following table :
