AND HORTICULTURE. 15 
continued to May 18, but then followed eight days with 
a burning sun and warmth exceptional even for Burgundy. 
From this time the plants on the experimental field began 
to languish, and the berries gathered between June 7 and 
21 gave— 
Experimental field............ 8065 kg. or 157g. from one plant 
Control ae inn ekpeknas 7245 kg. or 185 ¢. 5 
or 15'r per cent. less from the experimental field. 
A difference in quality was also noticeable, the berries. 
from the control field being fresher and more fragrant, those 
from the experimental field sweeter. It was evident that 
the electricity had damaged the plants. Rightly to esti- 
mate the damage, the number of fruits was counted to- 
be on the average 16 on every plant on the experimental 
field, but only eight on the control field ; the fecundity had 
been twice as great on the experimental field. 
The cause of this unexpected change in the develop- 
ment must be sought in the electric current, and the con- 
sequence is that the quantity of this agent must be 
lessened in times of burning sun. But it will be seen that. 
an equal watering of both fields should have altered the 
result in favour of the experimental field. 
We must, then, conclude that electricity is not so harm- 
less that it may be given in an unlimited quantity; the 
external circumstances must be carefully considered. The 
same damaging through the burning sun happened with 
maize, which, in the beginning of May, showed an evident. 
greater activity.on the experimental field than on the 
control field, but was found afterwards to decline. 
In all the series of experiments the results showed that 
some of the plants were not favoured by electricity. Among 
these were carrots, cabbage, rooted cabbage, tobacco and peas. 
During the experiments in Burgundy it happened that, 
besides the areas upon the field, there were fields of experi- 
ment and control both for carrots and peas in the garden.. 
These four small fields, being of the same size, were equally-
