All the bonds that have been issued since February 12, 1873, when gold became the only unlimited legal-tender metallic currency of the country, are justly payable in gold coin or in coin of equal value. During the time of these issues the only dollar that could be or was received by the Government in exchange for bonds was the gold dollar. To require the public creditors to take in repayment any dollar of less commercial value would be regarded by them as a repudiation of the full obligation assumed. The bonds issued prior to 1873 were issued at a time when the gold dollar was the only coin in circulation or contemplated by either the Government or the holders of the bonds as the coin in which they were to be paid. It is far better to pay these bonds in that coin than to seem to take advantage of the unforeseen fall in silver bullion to pay in a new issue of silver coin thus made so much less valuable. The power of the United States to coin money and to regulate the value thereof ought never to be exercised for the purpose of enabling the Government to pay its obligations in a coin of less value than that contemplated by the parties when the bonds were issued. Any attempt to pay the national indebtedness in a coinage of less commercial value than the money of the world would involve a violation of the public faith and work irreparable injury to the public credit. It was the great merit of the act of March, 1869, in strengthening the public credit, that it removed all doubt as to the purpose of the United States to pay their bonded debt in coin. That act was accepted as a pledge of public faith. The Government has derived great benefit from it in the progress thus far made in refunding the public debt at low rates of interest. An adherence to the wise and just policy of an exact observance of the public faith will enable the Government rapidly to reduce the burden of interest on the national debt to an amount exceeding $20,000,000 per annum, and effect an aggregate saving to the United States of more than $300,000,000 before the bonds can be fully paid. In adapting the new silver coinage to the ordinary uses of currency in the everyday transactions of life and prescribing the quality of legal tender to be assigned to it, a consideration of the first importance should be so to adjust the ratio between the silver and the gold coinage, which now constitutes our specie currency, as to accomplish the desired end of maintaining the circulation of the two metallic currencies and keeping up the volume of the two precious metals as our intrinsic money. It is a mixed question, for scientific reasoning and historical experience to determine, how far and by what methods a practical equilibrium can be maintained which will keep both metals in circulation in their appropriate spheres of common use.
