While the cause of the above changes is to be found chiefly 
in the change in the areas under the various crops, the extent of 
the changes is affected in some degree by the alterations in average 
yield to which attention has already been drawn. For example, 
the increase in average yield per acre between 1891-1900 and 
1901-10 was not sufficient to prevent a reduction in the total 
production of corn, but it restricted the decline in the average 
wheat production to 124,000 tons, or about 8 per cent., although 
the area declined by 246,000 acres or 13 per cent. The total yield 
of oats in the same period showed an increase of 8 per cent. 
although the acreage under oats in the country had increased by 
only 2 per cent. 
The period from 1911 to 1920 is of course exceptional in that 
the corn area was increased substantially during the war. But 
total yields of corn crops since 1921, averaging in the aggregate 
4,290,000 tons per annum (excluding rye), have been nearly 
6 per cent. below the average for the 10 years up to 1910 when 
the total yield was about 4,550,000 tons, while the average 
acreage under these crops has been reduced by less than 3 per 
cent. During the past five years, however, there have been 
very substantial changes in the acreage under the various crops 
and the total corn production in 1925 amounted to only 4,066,000 
tons, or about 11 per cent. below the average production of 
1901-10, 
Wheat. —The extent of wheat growing as compared with that of 
other crops on arable land varies very greatly in different parts of 
the country. In Map V are shown the proportions of wheat 
to total arable area in the different counties in 1925, Huntingdon 
and the Isle of Ely, each with over 28 per cent. of their arable 
area under wheat, are the counties in which wheat growing is 
relatively most extensive and, radiating from this centre, the 
proportion of wheat becomes gradually smaller until in the 
extreme north-west and south-west the proportion is less than 
5 per cent. The proportion of the arable area now occupied by 
this erop over the whole of England and Wales is 14 per cent. The
