The framers of the Constitution, when they gave to Congress the power "to coin money and to regulate the value thereof" and prohibited the States from coining money, emitting bills of credit, or making anything but gold and silver coin a tender in payment of debts, supposed they had protected the people against the evils of an excessive and irredeemable paper currency. They are not responsible for the existing anomaly that a Government endowed with the sovereign attribute of coining money and regulating the value thereof should have no power to prevent others from driving this coin out of the country and filling up the channels of circulation with paper which does not represent gold and silver. It is one of the highest and most responsible duties of Government to insure to the people a sound circulating medium, the amount of which ought to be adapted with the utmost possible wisdom and skill to the wants of internal trade and foreign exchanges. If this be either greatly above or greatly below the proper standard, the marketable value of every man's property is increased or diminished in the same proportion, and injustice to individuals as well as incalculable evils to the community are the consequence. Unfortunately, under the construction of the Federal Constitution which has now prevailed too long to be changed this important and delicate duty has been dissevered from the coining power and virtually transferred to more than 1,400 State banks acting independently of each other and regulating their paper issues almost exclusively by a regard to the present interest of their stockholders. Exercising the sovereign power of providing a paper currency instead of coin for the country, the first duty which these banks owe to the public is to keep in their vaults a sufficient amount of gold and silver to insure the convertibility of their notes into coin at all times and under all circumstances. No bank ought ever to be chartered without such restrictions on its business as to secure this result. All other restrictions are comparatively vain. This is the only true touchstone, the only efficient regulator of a paper currency--the only one which can guard the public against overissues and bank suspensions. As a collateral and eventual security, it is doubtless wise, and in all cases ought to be required, that banks shall hold an amount of United States or State securities equal to their notes in circulation and pledged for their redemption. This, however, furnishes no adequate security against overissues. On the contrary, it may be perverted to inflate the currency. Indeed, it is possible by this means to convert all the debts of the United States and State Governments into bank notes, without reference to the specie required to redeem them. However valuable these securities may be in themselves, they can not be converted into gold and silver at the moment of pressure, as our experience teaches, in
