28 ZLECTRICITY IN AGRICULTURE 
We must, however, regard this result as uncertain, because 
the control field 1 showed from the beginning a high degree 
of development, and had to be excluded from comparison. 
Control field 3 was again situated in the column of squares 
the fertility of which was too great. When we take that 
into consideration, and use the same minimum number of 
reduction as above, or 1°4, the increase will be 
75°I per cent. hay and 83°3 per cent. seed. 
The uncertainty is, however, great in this experiment, 
and the percentage of increase can hardly be determined.

If the control field 2 is excluded, as the fertility is too 
great for comparison, and if No.1 is divided by o8 and 
No. 3 by 14, the increase will be 36°6 per cent. 
At the same time, it seems that the first average harvest 
from the experimental field will surpass that from the 
control field if the latter is treated in the way recommended, 
which shows an earlier development on the former. 
Currants. 
On the squares planted with currants, the number of 
bushes which had begun to grow in the experimental field 
and in the control field was very different, so that, regarding 
the quantity, no comparable results could be obtained.
