CHAPTER XXI.
OF THE DISTRIBUTION OF THE PRECIOUS METALS THROUGH THE COMMERCIAL WORLD.
§ 1.Having now examined the mechanism by which the commercial transactions between nations are actually conducted, we have next to inquire whether this mode of conducting them makes any difference in the conclusions respecting international values, which we previously arrived at on the hypothesis of barter.
The nearest analogy would lead us to presume the negative. We did not find that the intervention of money and its substitutes made any difference in the law of value as applied to adjacent places. Things which would have been equal in value if the mode of exchange had been by barter, are worth equal sums of money. The introduction of money is a mere addition of one more commodity, of which the value is regulated by the same laws as that of all other commodities. We shall not be surprised, therefore, if we find that international values also are determined by the same causes under a money and bill system, as they would be under a system of barter; and that money has little to do in the matter, except to furnish a convenient mode of comparing values.
All interchange is, in substance and effect, barter: whoever sells commodities for money, and with that money buys other goods, really buys those goods with his own commodities. And so of nations: their trade is a mere exchange of exports for imports; and whether money is employed or not, things are only in their permanent state when the exports and imports exactly pay for each other. When this is the case, equal sums of money are due from each country to the other,
