Although it may not be possible by any legislative means within our power to change at once the system which has thus been introduced, and has received the acquiescence of all portions of the country, it is certainly our duty to do all that is consistent with our constitutional obligations in preventing the mischiefs which are threatened by its undue extension. That the efforts of the fathers of our Government to guard against it by a constitutional provision were founded on an intimate knowledge of the subject has been frequently attested by the bitter experience of the country. The same causes which led them to refuse their sanction to a power authorizing the establishment of incorporations for banking purposes now exist in a much stronger degree to urge us to exert the utmost vigilance in calling into action the means necessary to correct the evils resulting from the unfortunate exercise of the power, and it is hoped that the opportunity for effecting this great good will be improved before the country witnesses new scenes of embarrassment and distress. Variableness must ever be the characteristic of a currency of which the precious metals are not the chief ingredient, or which can be expanded or contracted without regard to the principles that regulate the value of those metals as a standard in the general trade of the world. With us bank issues constitute such a currency, and must ever do so until they are made dependent on those just proportions of gold and silver as a circulating medium which experience has proved to be necessary not only in this but in all other commercial countries. Where those proportions are not infused into the circulation and do not control it, it is manifest that prices must vary according to the tide of bank issues, and the value and stability of property must stand exposed to all the uncertainty which attends the administration of institutions that are constantly liable to the temptation of an interest distinct from that of the community in which they are established. The progress of an expansion, or rather a depreciation, of the currency by excessive bank issues is always attended by a loss to the laboring classes. This portion of the community have neither time nor opportunity to watch the ebbs and flows of the money market. Engaged from day to day in their useful toils, they do not perceive that although their wages are nominally the same, or even somewhat higher, they are greatly reduced in fact by the rapid increase of a spurious currency, which, as it appears to make money abound, they are at first inclined to consider a blessing.
