i
the total net increase amounted to no more than 28,000 acres,
an increase which was promptly succeeded by a decline of
94,000 acres in 1918.
Total Agricultural Area. —1f to the area under crops and
permanent pasture is added the area under rough grazings, which
were first returned in 1891, it will be found that the total area of
agricultural land, inclusive of rough grazings, was 30,599,000
acres in 1892* ag against 30,779,779 acres in 1925. This increase
does not, however, represent an actual expansion in the total
agricultural area as the returns of rough grazings have recently
been made much more complete than they formerly were.
There was also a substantial increase in rough grazings between
1892 and 1898 which was also probably due to a similar cause.
Between 1898 and 1911 the alterations in the total agricultural
area in any one year did not exceed about 20,000 acres, but after
1911 the changes became more substantial. There was a big
decline in 1915 which was probably due to the occupation of
large areas for military purposes throughout the country. But
the necessities of war and the high prices of the period resulted
in increases in 1916 and 1917, and the area was about maintained
in 1918, but the following year saw a substantial fall. In recent
years efforts have been made to set the collection of statistics
of rough grazings upon a more satisfactory footing, and some of
the fluctuations since the close of the war are due to more complete
returns, but on the other hand much land which was ploughed
up as a war-time measure ceased to be so cultivated when the
urgency of the need had disappeared, and it would seem that a
proportion of the area has been allowed to revert to rough grazing.
In the years between 1920 and 1925 the decrease in the cultivated
area appears to have been largely compensated for by the increase
in rough grazings.
Figures showing for five-year periods the areas returned in
these different groups since 1871-75 are given in Table 2 in the
Appendix.
7. The Conversion from Arable to Grass land.—During the
period from 1871 to 1925 there was, as is well known, a very
considerable conversion of arable land into pasture. At the
beginning of the period rather less than three-fifths of the
cultivated land in the country was under arable, at the end of
the period nearly three-fifths was under permanent pasture.
The extent of the change during the last fifty years is illustrated
by Maps II and III. The eastern counties are those in which
the change from arable to grass is the least marked, but over
the greater part of the country something more than 60 per cent.
of the cultivated area is now under permanent grass. In every
county except Cheshire, Lancashire, Lincoln (Holland) and
Middlesex, the proportion of arable land has declined in the

far from complete,
