in 1925. The increase in engines of this type far outweighs in 
importance the changes in the use of other forms of fixed or 
portable engines. 
The number of motor tractors is returned as nearly 16,700. 
The numbers were not ascertained in 1908 or 1913, but they were 
at that time very small, and practically the whole number may 
be regarded as additional and as marking a new development 
in the substitution of mechanical motive power for horse power 
on the farm. 
The number of agricultural engines of each kind used per 
10,000 acres of crops and grass in each agricultural division of 
the country presents a few interesting features. The following 
table shows the engines employed in relation to the aggregate 
area. of the farms from which returns were received in each 
division :—

The above figures refer to the number of engines of all sizes 
but do not give any indication of their horse power. It is not 
possible, therefore, to make accurate deductions as to the actual 
power consumption of the different agricultural divisions. 
Steam power is used mainly on the arable farms of the eastern 
and midland counties, while the use of gas and electric engines is 
most widespread in the northern and north-western divisions 
where rural supplies of gas and electricity are more readily 
available. Oil and petrol engines are more numerous in pasture 
than in arable counties, since the chief use of such engines is for 
preparing food for livestock. Wind power is fairly evenly utilised 
throughout the country, but water-power is used more extensively 
in Wales than in any other part of the country.
