installation. This great difference comes from the very low 
price of wheat in Great Britain. The price per bushel 
varies very much :—

Though the above calculations on the financial side of 
the question are merely approximate there will undoubtedly 
be great pecuniary advantage in applying the electrical 
treatment, when we take into consideration not only the 
increase in the harvest but also the improvement of the 
crops, as shown by the chemical analyses. That the electri- 
cal air-current will prove of great service in orchards and on 
large market growing lands, by inducing earliness and rapid 
maturity as well as increased crops, seems to be clearly 
demonstrated. 
' The cost of the installation includes the electrical 
machine, which is put down for a sum of 432, or $164, and 
this sum may be regarded as very high in comparison with 
the cost of the older machines, But my own experience 
will here be useful. He who would avoid the troubles I 
experienced in working with. the older machine will not 
hesitate to use the new type, with its opposite-direction 
rotating cylinders. This new type of influence-machine has 
the following advantagesin comparison with the older ones:— 
The New Machine. 
(Glass cylinders 40 cm. in length 
and 30 cm. in diam.) 
1. It never 
charged. { 
fails to be 
2. It can be kept at work 
during several months continu- 
ously. 
3. It can be used on a greater 
area (say up to 10 hectares). 
The Older Machine. 
(45 cm. plates.) 
1. The older machine fails 
very often to be charged, espe- 
cially in the summer, when the 
air is sultry and humid. 
. 2. When at work it must be 
cleaned every third day. 
3. It can only be used upon an 
area not exceeding 2°5 hectares.

+ Russian wheat. 
~ Excepting when the air is vadzo-actzve, which will occur very seldom, ‘say 
four or five times in the summer, and then only for a few hours.
