the debts are settled by bills, and there is no balance to be paid in the precious metals. The trade is in a state like that which is called in mechanics a condition of stable equilibrium.
But the process by which things are brought back to this state when they happen to deviate from it, is, at least outwardly, not the same in a barter system and in a money system. Under the first, the country which wants more imports than its exports will pay for, must offer its exports at a cheaper rate, as the sole means of creating a demand for them sufficient to re-establish the equilibrium. When money is used, the country seems to do a thing totally different. She takes the additional imports at the same price as before, and as she exports no equivalent, the balance of payments turns against her; the exchange becomes unfavourable, and the difference has to be paid in money. This is in appearance a very distinct operation from the former. Let us see if it differs in its essence, or only in its mechanism.
Let the country which has the balance to pay be England, and the country which receives it, France. By this transmission of the precious metals, the quantity of the currency is diminished in England, and increased in France. This I am at liberty to assume. As we shall see hereafter, it would be a very erroneous assumption if made in regard to all payments of international balances. A balance which has only to be paid once, such as the payment made for an extra importation of corn in a season of dearth, may be paid from hoards, or from the reserves of bankers, without acting on the circulation. But we are now supposing that there is an excess of imports over exports, arising from the fact that the equation of international demand is not yet established: that there is at the ordinary prices a permanent demand in England for more French goods than the English goods required in France at the ordinary prices will pay for. When this is the case, if a change were not made in the prices,
