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 * The returns of rough grazings in 1891 were stated to have been very far from complete,
