The history of agriculture in the eighteenth century is remarkable for several features of great importance. It first saw the application of capital in large quantities to farming, the improvements of the time being largely initiated by rich landowners whom Young praises rightly as public-spirited men who deserved well of their country, though Thorold Rogers attributes a meaner motive for the improvement of their estates, namely, their desire not to be outshone by the wealthy merchants.[367] They were often ably assisted by tenant farmers, many of whom were now men with considerable capital, for whom the smaller farms were amalgamated into large ones. After the agricultural revolution of the latter half of the century, the tendency to consolidate small holdings into large farms grew apace and was looked on as a decided mark of progress. This agricultural revolution was largely a result of the industrial revolution that then took place in England. Owing to mechanical inventions and the consequent growth of the factory system, the great manufacturing towns arose, whence came a great demand for food, and, to supply this demand, farms, instead of being small self-sufficing holdings just growing enough for the farmer and his family and servants, grew larger, and became manufactories of corn and meat. The century was also remarkable for another great change. England, hitherto an exporting country, became an importing one. The progress of the century was furthered by a band of men whose names are, or ought to be, household words with English farmers: Jethro Tull, Lord Townshend, Arthur Young, Bakewell, Coke of Holkham, and the Collings. Further the century witnessed a great number of enclosures, especially when it was drawing to its close. According to the Report of the Committee on Waste Lands in 1797, the number of Enclosure Acts was: under Anne, 2 Acts, enclosing 1,439 acres; under Geo. I, 16 Acts, enclosing 17,960 acres; under Geo. II, 226 Acts, enclosing 318,778 acres; from 1760 to 1797, 1,532 Acts, enclosing 2,804,197 acres.
