often do not even pass through the same hands. Each is separately bought and paid for with money. We have seen, however, that, even in the same country, money does not actually pass from hand to hand each time that purchases are made with it, and still less does this happen between different countries. The habitual mode of paying and receiving payment for commodities, between country and country, is by bills of exchange.
A merchant in England, A, has exported English commodities, consigning them to his correspondent B in France. Another merchant in France, C, has exported French commodities, suppose of equivalent value, to a merchant D in England. It is evidently unnecessary that B in France should send money to A in England, and that D in England should send an equal sum of money to C in France. The one debt may be applied to the payment of the other, and the double cost and risk of carriage be thus saved. A draws a bill on B for the amount which B owes to him: D, having an equal amount to pay in France, buys this bill from A, and sends it to C, who, at the expiration of the number of days which the bill has to run, presents it to B for payment. Thus the debt due from France to England, and the debt due from England to France, are both paid without sending an ounce of gold or silver from one country to the other.
In this statement, however, it is supposed, that the sum of the debts due from France to England, and the sum of those due from England to France, are equal; that each country has exactly the same number of ounces of gold or silver to pay and to receive. This implies (if we exclude for the present any other international payments than those occurring in the course of commerce), that the exports and imports exactly pay for one another, or in other words, that the equation of international demand is established. When such is the fact, the international transactions are liquidated without the passage of any money from one country to the other. But if there is a greater sum due from England to
