7O ELECTRICITY IN AGRICULTURE 
REVENUE, 
We will take the wheat as a crop at medium price to 
estimate the revenue from the application of the electrical 
air-current. A field sown with wheat gives, speaking 
generally, 34 bushels per acre as an average crop on ordinary 
good wheat land; then an increase of 45 per cent. on 25 
acres, or say Io hectares, is equal to 383 bushels. 
383 bushels at 3s. 6d. per bushel equals... 467 o 6 
Less the yearly COSt..........esseseseeeeeaee 23 3 6 
The net profit on 24 acres equals ... £43 17 0 
Or more than four-tenths of the whole cost of the com- 
plete installation will be realised in the first year. 
As the cost of the installation does not increase in direct 
proportion to the area of land treated, it follows that on 
larger areas the profits would be greater, whereas on a very 
small area (1 or 2 acres) the increased crop would not pay 
for the application of the electric current. 
In the case of horticulture, however, it is an-entirely 
different matter. The produce has a much higher value, 
and the electrical treatment will always repay the cost when 
the area is not too small and is very intensively cultivated. 
In this department of agricultural work, therefore, the 
future for the electrical treatment of growing crops has a 
most promising future. . 
Remarks.—I\n other countries, where the wheat prices are 
much higher, this process of calculation will give, generally 
speaking, 30 hectolitres* per hectare, or 300 hectolitres for 
10 hectares. In these countries also the capital cost and 
maintenance charges are, speaking generally, lower than in 
the United Kingdom. The electrical treatment gives an 
increase of 45 per cent. Therefore — 
135 hectolitres at 15°38. per hectolitre, equals “£103 5 6 
Less the yearly COSt ....ccsceseeseeeee o teeeeeees 23 3 «6 
The net profit on ro hectares will be ......... £80 2 0° 
or nearly ¢hree-guarters of the whole cost of the complete 
* Qne hectolitre equals 2°751 bushels.
