It will be perceived that the agriculturists, though only about half a million more in numbers than the manufacturing classes, had a far larger proportionate income, in fact more than double. This was of course partly due to the agricultural improvements of this period, and to the fact that manufactures were still carried on almost solely by hand, thus giving only a small production from a good many workmen. But the Industrial Revolution rapidly changed all this, and now agriculture is no longer the staple industry of the country. We may here refer to what has been previously mentioned in regard to the agricultural development on enclosed land, and to the superiority of the results of enclosures over common fields. Those farmers and large owners who understood the best ways of raising crops prospered, and more and more land was enclosed every year to grow corn (which by the way was rapidly rising in price), clover, turnips and other root-crops. No less than 700 Enclosure Acts were passed between 1760 and 1774. The old common fields were beginning to disappear, and the working classes also lost their rights of pasturing cattle on the wastes, for wastes now were enclosed. It must be admitted that the old common-field system produced very poor results (cf. p. 41), but the loss of his common rights was very {155} disastrous to the labourer, for it drove him off the land at the same time as the growth of manufactures attracted him off from it, and thus the labourer became in a few years completely divorced from the soil. At present attempts are being made to attract him back to it by offering him small strips of inferior land at a high rent. This is known as the allotment system. It need scarcely be said that, as at present carried out, it is hardly likely to succeed.[45] [45. For recent developments, _v._ p. 231.]
