Rh mean time the balance may turn the other way, and restore the equality of debts and credits without any actual transmission of the metals. And this is the more likely to happen, as there is a self-adjusting power in the variations of the exchange itself. Bills are at a premium because a greater money value has been imported than exported. But the premium is itself an extra profit to those who export. Besides the price they obtain for their goods, they draw for the amount and gain the premium. It is, on the other hand, a diminution of profit to those who import. Besides the price of the goods, they have to pay a premium for remittance. So that what is called an unfavourable exchange is an encouragement to export, and a discouragement to import. And if the balance due is of small amount, and is the consequence of some merely casual disturbance in the ordinary course of trade, it is soon liquidated in commodities, and the account adjusted by means of bills, without the transmission of any bullion. Not so, however, when the excess of imports above exports, which has made the exchange unfavourable, arises from a permanent cause. In that case, what disturbed the equilibrium must have been the state of prices, and it can only be restored by acting on prices. It is impossible that prices should be such as to invite to an excess of imports, and yet that the exports should be kept permanently up to the imports by the extra profit on exportation derived from the premium on bills; for if the exports were kept up to the imports, bills would not be at a premium, and the extra profit would not exist. It is through the prices of commodities that the correction must be administered.

Disturbances, therefore, of the equilibrium of imports and exports, and consequent disturbances of the exchange, may be considered as of two classes; the one casual or accidental, which, if not on too large a scale, correct themselves through the premium on bills, without any transmission of the precious metals; the other arising from the general state of prices, which cannot be corrected without the subtraction of actual
