At other times manufactures for distant sale grow up naturally, and as it were of their own accord, by the gradual refinement of those houshold and coarser manufactures which must at all times be carried on even in the poorest and rudest countries. Such manufactures are generally employed upon the materials which the country produces, and they seem frequently to have been first refined and improved in such inland countries as were, not indeed at a very great, but at a considerable distance from the sea coast, and sometimes even from all water carriage. An inland country naturally fertile and easily cultivated, produces a great surplus of provisions beyond what is necessary for maintaining the cultivators, and on account of the expence of land carriage, and inconveniency of river navigation, it may frequently be difficult to send this surplus abroad. Abundance, therefore, renders provisions cheap, and encourages a great number of workmen to settle in the neighbourhood, who find that their industry can there procure them more of the necessaries and conveniencies of life than in other places. They work up the materials of manufacture which the land produces, and exchange their finished work, or what is the same thing the price of it, for more materials and provisions. They give a new value to the surplus part of the rude produce, by saving the expence of carrying it to the water side, or to some distant market; and they furnish the cultivators with something in exchange for it that is either useful or agreeable to them, upon easier terms than they could have obtained it before. The cultivators get a better price for their surplus produce, and can purchase cheaper other conveniencies which they have occasion for. They are thus both encouraged and enabled to increase this surplus produce by a further improvement and better cultivation of the land; and as the fertility of the land had given birth to the manufacture, so the progress of the manufacture re-acts upon the land, and increases still further its fertility. The manufacturers first supply the neighbourhood, and afterwards, as their work improves and refines, more distant markets. For though neither the rude produce, nor even the coarse manufacture, could, without the greatest difficulty, support the expence of a considerable land carriage, the refined and improved manufacture easily may. In a small bulk it frequently contains the price of a great quantity of rude produce. A piece of fine cloth, for example, which weighs only eighty pounds, contains in it, the price, not only of eighty pounds weight of wool, but sometimes of several thousand weight of corn, the maintenance of the different working people, and of their immediate employers. The corn, which could with difficulty have been carried abroad in its own shape, is in this manner virtually exported in that of the complete manufacture, and may easily be sent to the remotest corners of the world. In this manner have grown up naturally, and as it were of their own accord, the manufactures of Leeds, Halifax, Sheffield, Birmingham, and Wolverhampton. Such manufactures are the offspring of agriculture. In the modern history of Europe, their extension and improvement have generally been posterior to those which were the offspring of foreign commerce. England was noted for the manufacture of fine cloths made of Spanish wool, more than a century before any of those which now flourish in the places above mentioned were fit for foreign sale. The extension and improvement of these last could not take place but in consequence of the extension and improvement of agriculture, the last and greatest effect of foreign commerce, and of the manufactures immediately introduced by it, and which I shall now proceed to explain.
