| “ | Without the assistance of some artificers, indeed, the cultivation of land cannot be carried on but with great inconveniency and continual interruption. Smiths, carpenters, wheel-wrights, and plough-wrights, masons, and bricklayers, tanners, shoemakers, and tailors are people whose service the farmer has frequent occasion for. Such artificers, too, stand occasionally in need of the assistance of one another; and as their residence is not, like that of the farmer, necessarily tied down to a precise spot, they naturally settle in the neighbourhood of one another, and thus form a small town or village. The butcher, the brewer, and the baker soon join them, together with many other artificers and retailers, necessary or useful for supplying their occasional wants, and who contribute still further to augment the town. The inhabitants of the town and those of the country are mutually the servants of one another. The town is a continual fair or market, to which the inhabitants of the country resort in order to exchange their rude for manufactured produce. It is this commerce which supplies the inhabitants of the town both with the materials of their work, and the means of their subsistence. The quantity of the finished work which they sell to the inhabitants of the country necessarily regulates the quantity of the materials and provisions which they buy. Neither their employment nor subsistence, therefore, can augment but in proportion to the augmentation of the demand from the country for finished work; and this demand can augment only in proportion to the extension of improvement and cultivation. Had human institutions, therefore, never disturbed the natural course of things, the progressive wealth and increase of the towns would, in every political society, be consequential, and in proportion to the improvement and cultivation of the territory or country. | ” |
