Rh This function of banks in filling up the gap made in mercantile credit by the consequences of undue speculation and its revulsion, is so entirely indispensable, that if the Act of 1844 continues unrepealed, there can be no difficulty in foreseeing that its provisions must be suspended, as they were in 1847, in every period of great commercial difficulty, as soon as the crisis has really and completely set in. Were this all, there would be no absolute inconsistency in maintaining the restriction as a means of preventing a crisis, and relaxing it for the purpose of relieving one. But there is another objection, of a still more radical and comprehensive character, to the new system.

Professing, in theory, to require that a paper currency shall vary in its amount in exact conformity to the variations of a metallic currency, it provides, in fact, that in every case of an efflux of gold, a corresponding diminution shall take place in the quantity of bank notes; in other words, that every exportation of the precious metals shall be virtually drawn from the circulation; it being assumed that this would be the case if the currency were wholly metallic. This theory, and these practical arrangements, are adapted to the case in which the drain of gold originates in a rise of prices produced by an undue expansion of currency or credit; but they are adapted to no case beside.

When the efflux of gold is the last stage of a series of effects arising from an increase of the currency, or from an expansion of credit tantamount in its effect on prices to an increase of currency, it is in that case a fair assumption that in a purely metallic system the gold exported would be drawn from the currency itself; because such a drain, being in its nature unlimited, will necessarily continue as long as currency and credit are undiminished. But an exportation of the
