[| 10 Pay Motor tractors, both for field work and for stationary work, are found chiefly in the eastern and south-eastern divisions, and least in Wales and the south-west, where conditions as regards type of farming and size of farms are least favourable to their widespread use. In connection with the inquiry regarding motive power an endeavour was made for the first time to ascertain the kind of machine driven by each type of motive power classified. About 15 per cent. of the farmers who stated the number of engines employed failed to indicate the uses to which they devoted them, but the replies given by the remaining 85 per cent. give an approximate indication of the uses of motive power on farms in England and Wales as a whole. Most engines on farms are, of course. used for more than one purpose. In the following table are shown the kinds of machines driven by the different forms of fixed or portable engines expressed as a percentage of the number of engines employed. The table excludes all returns in which the machinery driven by the engines was not indicated. PERCENTAGE OF ToTAL ENGINES oF DIFFERENT Types ox FARMS WHICH ARE USED FOR VARIOUS OPERATIONS.
