It would require much reading and research to elaborate the details of this progress, and for our present purpose it is hardly necessary, as it involved alteration in particulars but not in the general organisation of household economy. The difficulties of finding domestic servants begin, however, to make themselves felt, and are amusingly discussed by such writers as Defoe and Swift. It is at some time during this period that houses are first built in terraces and squares on an identical plan for letting purposes. But there are no sweeping changes, such as mark the eighty years before the accession of Victoria. (3) _The Influence of the Second Industrial Revolution on the Home_ In the last half of the eighteenth century agriculture and industry were once more revolutionised, the former by the introduction of capitalist farming, the rotation of crops, and the further enclosure of common fields, commons, and wastes, the latter by the introduction of machinery and mechanical motor power. For a detailed account of the enormous changes consequent on these new methods of production, I must refer the reader to the special treatises on the subject,[64] but we must spend some time in considering the ways in which the home, family life, and the position of women have been modified by these industrial developments. In the first place, the introduction of machinery meant the growth of the factory system, and in consequence work left the home, which ceased to be the institution where productive industry was carried on, and became instead a centre solely of emotional and domestic life. At the same time, the alteration in the land system made it impossible any longer to combine home weaving, spinning, &c. with subsistence farming; the worker becomes an employee in a business where the capital is owned by his employer, and he depends absolutely on the skill of his own hands for his livelihood.
