their land and labor for which there is no demand among them, and brings back in return for it something else for which there is a demand. It gives a value to their superfluities, by exchanging them for something else, which may satisfy a part of their wants, and increase their enjoyments. By means of it, the narrowness of the home market does not hinder the division of labor in any particular branch of art or manufacture from being carried to the highest perfection. By opening a more extensive market for whatever part of the produce of their labor may exceed the home consumption, it encourages them to improve its productive powers, and to augment its annual produce to the utmost, and thereby to increase the real revenue and wealth of the society. These great and important services foreign trade is continually occupied in performing, to all the different countries between which it is carried on. They all derive great benefit from it, though that in which the merchant resides generally derives the greatest, as he is generally more employed in supplying the wants, and carrying out the superfluities of his own, than of any other particular country. To import the gold and silver which may be wanted, into the countries which have no mines, is, no doubt, a part of the business of foreign commerce. It is, however, a most insignificant part of it. A country which carried on foreign trade merely upon this account, could scarce have occasion to freight a ship in a century.
It is not by the importation of gold and silver that the discovery of America has enriched Europe. By the abundance of the American mines those metals have become cheaper. A service of plate can now be purchased for about a third part of the corn, or a third part of the labor, which it would have cost in the fifteenth century. With
