The truth is that while, during a legalized inconvertibility of bank-notes, an efflux of gold may, and often does, indicate an excessive issue of bank-notes; under ordinary circumstances an efflux of gold has little or nothing to do with the issue of bank-notes, but is determined by merely mercantile causes. And the truth is that far from being an evil, an efflux of gold thus brought about by mercantile causes, is a good. Leaving out of the question, as of course we must, such exportations of gold as take place for the support of armies abroad; the cause of efflux is either an actual plethora of all commodities, gold included, which results in gold being sent out of the country for the purpose of foreign investment; or else an abundance of gold as compared with other leading commodities. And while, in this last case, the efflux of gold indicates some absolute or relative impoverishment of the nation, it is a means of mitigating the bad consequences of that impoverishment. Consider the question as one of political economy, and this truth becomes obvious. Thus:—The nation habitually requires for use and consumption certain quantities of commodities, of which gold is one. These commodities {343} are severally and collectively liable to fall short; either from deficient harvests, from waste in war, from losses abroad, or from too great a diversion of labour or capital in some special direction. When a scarcity of some chief commodity or necessary occurs, what is the remedy? The commodity of which there is an excess (or if none is in excess, then that which can best be spared) is exported in exchange for an additional supply of the deficient commodity. And, indeed, the whole of our foreign trade, alike in ordinary and extraordinary times, consists in this process. But when it happens either that the commodity which we can best spare is not wanted abroad; or (as recently) that a chief foreign customer is temporarily disabled from buying; or that the commodity which we can best spare is gold; then gold itself is exported in exchange for the thing which we most want. Whatever form the transaction takes, it is nothing but bringing the supplies of various commodities into harmony with the demands for them. The fact that gold is exported, is simply a proof that the need for gold is less than the need for other things. Under such circumstances an efflux of gold will continue, and _ought_ to continue, until other things have become relatively so abundant, and gold relatively so scarce, that the demand for gold is equal to other demands. And he who would prevent this process, is about as wise as the miser who, finding his house without food, chooses to starve rather than draw upon his purse.
