In the more highly developed and specialised textile trades certain regular market-places were established of wide local importance. The largest of these specialised district markets were at Leeds, Halifax, Norwich, and Exeter. Here the chief local manufacturers of cloth, worsted, or crape met the merchants and factors and disposed of their wares to these distributing middlemen. It was, however, in the general market-places of the county town or smaller centres of population that the mass of the business of exchange was transacted. There the mass of the small workers in agriculture and manufacture brought the product of their labour and sold it, buying what they needed for consumption and for the pursuance of their craft. Only in considerable towns were there to be found in the earlier eighteenth century any number of permanent shops where all sorts of wares could be bought at any time. The weekly market in the market-town was the chief medium of commerce for the great mass of the population. Regarding the general structure of Industry we see that not only are international bonds slight and unessential, but that within the nation the elements of national cohesion are feeble as compared with those which subsist now. We have a number of small local communities whose relations, though tolerably strong with other communities in their immediate neighbourhood, become greatly weakened by distance. For the most part these small communities are self-sufficing for work and life, producing most of their own necessaries, and only dependent on distant and unknown producers for their comforts and luxuries. Trade is for the most part conducted on a small steady local basis with known regular customers. Outside of agriculture the elements of speculation and fluctuation are almost entirely confined to foreign trade. Capital and labour are fixed to a particular locality and a particular business.[36] § 9. Turning to the structure of the several industries we find that different employments are not sharply separated from one another. In the first place, agriculture and manufacture are not only carried on in the same locality but by the same people. This combined agriculture and manufacture took several forms. The textile industries were largely combined with agriculture. Where spinning was carried on in agricultural parts there was, for the most part, a division of labour within the family. The women and children spun while the men attended to their work in the fields.[37] Every woman and child above the age of five found full employment in the spinning and weaving trades of Somerset and the West Riding.[38]
