Manufactures, as in a small bulk they frequently contain a great value, and can upon that account be transported at less expense from one country to another than most parts of rude produce, are, in almost all countries, the principal support of foreign trade. In countries, besides, less extensive and less favourably circumstanced for interior commerce than China, they generally require the support of foreign trade. Without an extensive foreign market, they could not well flourish, either in countries so moderately extensive as to afford but a narrow home market; or in countries where the communication between one province and another was so difficult, as to render it impossible for the goods of any particular place to enjoy the whole of that home market which the country could afford. The perfection of manufacturing industry, it must be remembered, depends altogether upon the division of labour; and the degree to which the division of labour can be introduced into any manufacture, is necessarily regulated, it has already been shown, by the extent of the market. But the great extent of the empire of China, the vast multitude of its inhabitants, the variety of climate, and consequently of productions in its different provinces, and the easy communication by means of water carriage between the greater part of them, render the home market of that country of so great extent, as to be alone sufficient to support very great manufactures, and to admit of very considerable subdivisions of labour. The home market of China is, perhaps, in extent, not much inferior to the market of all the different countries of Europe put together. A more extensive foreign trade, however, which to this great home market added the foreign market of all the rest of the world; especially if any considerable part of this trade was carried on in Chinese ships; could scarce fail to increase very much the manufactures of China, and to improve very much the productive powers of its manufacturing industry. By a more extensive navigation, the Chinese would naturally learn the art of using and constructing themselves all the different machines made use of in other countries, as well as the other improvements of art and industry which are practised in all the different
