From that time until the panic of 1873 their amount remained at $356,000,000. In the interval Mr. Boutwell had succeeded Mr. McCulloch, and Mr. Richardson had succeeded Mr. Boutwell as Secretary. Mr. Richardson, under diminished customs and revenue receipts, and the stress of the panic, restored to circulation $26,000,000 of the $44,000,000 of legal tender notes that had been withdrawn by Mr. McCulloch, whereupon Congress, on June 22, 1874, provided that the greenbacks in circulation should remain fixed at the then existing total of $382,000,000. The same law which thus legalized the reissue of the $26,000,000 of legal tender notes by Secretary Boutwell abolished the National Bank reserve, previously required to be kept on bank-note circulation, and for this substituted the provision that the banks were to deposit five per cent. in legal tender notes of the amount of their own note issues with the United States Treasurer at Washington for the redemption of their notes. This law is still in force, and the establishment of the Redemption Bureau at Washington has resulted, ever since, in daily receipts by it of mutilated bank notes to be replaced by new notes, in addition to the ebb and flow caused by banks increasing or reducing their circulation. The five per cent. in legal tender deposited is counted by them as part of their legal reserve. But the necessity of sending the notes to Washington, and of receiving them therefrom, involves trouble and loss of time to the banks, and also prevents the banks from contracting their circulation when the demand for it is light and increasing it when heavy, as freely and promptly as they would if every Sub-treasury was made a redemption point for National Banks. Congress ought therefore to authorize the equipment of the Sub-treasuries with redemption bureaus for the banks in their respective districts, in order to facilitate this ebb and flow of bank-note issues, and so increase the much needed elasticity of the currency. In addition to United States legal tender notes, large amounts of interest-bearing legal tender notes were issued during the war. On September 1, 1865, when the currency, like the whole National debt, reached its greatest amount of inflation, the noninterest-bearing legal tender notes and fractional currency stood at $459,505,311, the three years six per cent. compound interest legal tender notes at more than $217,000,000, and the one and two years five per cent. legal tender notes at nearly $34,000,000, the whole aggregating $685,236,269 issued by the Treasury.
