"By the constitution of the United States, Congress is expressly vested with the power to coin money, to regulate the value of domestic and foreign coin in circulation, and (as a necessary implication from positive provisions) to emit bills of credit; while it is declared by the same instrument that 'no state shall coin money, or emit bills of credit.' The constitutional authority to emit bills of credit has also been exercised in a qualified and limited manner. . . . "The constitutional and legal foundation of the monetary system of the United States is thus distinctly seen; and the power of the federal government to institute and regulate it, whether the circulating medium consist of coin or of bills of credit, must, in its general policy, as well as in the terms of its investment, be deemed an exclusive power." These extracts from a document of great ability, state the whole question in a few words. Congress has the power to regulate commerce; Congress has the power to borrow money, which involves the power to emit bills of credit; Congress has the power to regulate the value of coin. These powers are exclusive. When, by the force of circumstances beyond our control, the national coin disappears, either because of war or of other circumstances, Congress alone must furnish the substitute. No state has the power to interfere with this exclusive authority in Congress to regulate the national currency, or, in other words, to provide a substitute for the national coin. I next stated the objections to local banks. The first was the great number and diversity of bank charters. There were 1,642 banks in the United States, established by the laws of twenty-eight different states, and these laws were as diverse, I might say, as the human countenance. We had the state bank system with its branches. We had the independent system, sometimes secured by local bonds, sometimes by state bonds, sometimes by real estate, sometimes by a mixture of these. We had every diversity of the bank system in this country that has been devised by the wit of man, and all these banks had the power to issue paper money. With this multiplicity of banks, depending upon different organizations, it was impossible to have a uniform national currency, for its value was constantly affected by their issues. There was no common regulator; they were dependent on different systems. The clearing house system adopted in the city of New York applied only to that city. There was no check or control over these banks. There was a want of harmony and concert among them. Whenever a failure occurred, such as that of the Ohio Life Insurance and Trust Company, it operated like a panic in a disorganized army; all of the banks closed their doors at once and suspended specie payments.
