OF INTEREST.

Everything useful to the life of man arises from the ground; but few things arise in that condition which is requisite to render them useful. There must, therefore, besides the peasants and the proprietors of land, be another rank of men, who, receiving from the former the rude materials, work them into their proper form, and retain part for their own use and subsistence. In the infancy of society, these contracts betwixt the artisans and the peasants, and betwixt one species of artisans and another, are commonly entered into immediately by the persons themselves, who, being neighbours, are easily acquainted with each other’s necessities, and can lend their mutual assistance to supply them. But when men’s industry increases, and their views enlarge, it is found that the most remote parts of the state can assist each other as well as the more contiguous, and that this intercourse of good offices may be carried on to the greatest extent and intricacy. Hence the origin of merchants, the most useful race of men in the {p44} whole society, who serve as agents between those parts of the state that are wholly unacquainted and are ignorant of each other’s necessities. Here are in a city fifty workmen in silk and linen, and a thousand customers; and these two ranks of men, so necessary to each other, can never rightly meet till one man erects a shop, to which all the workmen and all the customers repair. In this province grass rises in abundance: the inhabitants abound in cheese, and butter, and cattle; but want bread and corn, which, in a neighbouring province, are in too great abundance for the use of the inhabitants. One man discovers this. He brings corn from the one province, and returns with cattle; and supplying the wants of both, he is, so far, a common benefactor. As the people increase in numbers and industry, the difficulty of their intercourse increases: the business of the agency or merchandise becomes more intricate, and divides, subdivides, compounds, and mixes to a greater variety. In all these transactions it is necessary, and reasonable, that a considerable part of the commodities and labour should belong to the merchant, to whom, in a great measure, they are owing. And these commodities he will sometimes preserve in
