LABOUR increasing A### 7 CAMPAIGN. REQUIREMENTS 3. While agriculture was able (though with. THE PLOUGHING difficulty) to carry on in peace-time with the diminished labour force by reducing the area under arable cultivation and by leaving maintenance work undone, the present supply of labour, both regular and casual, is wholly inadequate to cope with the increase of production contemplated for this year's harvest. Farmers in Great Britain are being required to cultivate three quarters of a million acres of land more than in 1929 with a regular labour force which, even in June 1939, was 143,000 or 19% less than in 1929.
