ENCLOSURES : ESSEX AGRICULTURE, 1500-1900. 21 since Wright in 1840 mentions that Fowlness and the adjacent mainland was being continuously increased by silt laid down by the sea. He further records that the draining of this marine silt provided valuable fertile land. It appears that the increase in the area of arable land occurring both here and in those few localities in the Boulder Clay country, to which reference has already been made, were the only districts to change from pastoral to arable farming during a period when the price of wheat was falling. The middle years of the nineteenth century saw the building •of the first railways in the County. The time, however, was not propitious for the improvement of agriculture. The fifties saw the beginning of the rapid fall in wheat prices and the consequent decline of Essex, which had not fostered and could not sustain any large-scale industry to balance its agricultural losses. It must also be remembered that Essex was heavily burdened by the tithe and land tax, and their effect accelerated the decline as soon as the high agricultural prices failed. These many changes occurring during the years 1801-61 have, so far, been correlated with the varying price of wheat. It should, however, be borne in mind that there must have been a steady drain of men to the rising industrial towns in the north of England. While it seems certain that these two factors affected the agriculture of the district, the bulk of the land was still under arable farming in the first year for which figures are available (1866). Throughout the greater part of the region 70 per cent, of the land was devoted to arable farming. With the exception of two parishes in the extreme south, that have extensive areas of saltings, only one parish had below 45 per cent, of its area in arable farming. The parish in question—Marks- hall—was, however, largely occupied by a private park. Great Braxted to the south-east had its arable percentage lowered by similar causes. Since 1840 (time of tithe maps), however, there had been a general reduction in the amount of arable land from about go per cent, to a figure approaching 75 per cent. This extensive reduction is sufficient to account, in large part, for the steady decline in population in the first half of the nineteenth century. The remaining years of the nineteenth century (1860-1900) and the first three decades of the present century witnessed
