At the time silver was demonetized it might well have been supposed that a sufficiently large unearned increment had already been realized by the foreign and domestic holders of United States bonds. The greater portion of the debt of the Government was, when incurred, made payable simply in "lawful money"--the interest alone being payable in coin. Yet in March, 1869, the bond-holders secured the passage of an act of Congress, entitled "An act to strengthen the public credit," containing a pledge to pay in coin or its equivalent not merely the interest, but the principal of all national obligations not specially provided to be paid otherwise. THE COURSE OF THE CREDITORS. And again, when in 1870 Congress was about to provide for a refunding of the public debt, these clamorous creditors, not satisfied with having got the bonds at rates much below their face value, and not satisfied with the pledge to pay in coin--a pledge made long after the contract was made and the debt incurred--insisted that not only should the new bonds be payable in coin, but in order to guard against any possible interpretation which might work to their detriment they did what has rarely been done in the history of monetary legislation, insisted that even the very _standard_ of that coin should be fixed and nominated in the bond. They were willing to take no chances. They were not willing to place confidence in the sense of equity and fair dealing of the people of the United States. They held before Congress the covert threat that if the new issue of bonds did not provide for payment in "coin," instead of "lawful money," and did not prescribe the precise standard of coin in which they were to be payable, it would be difficult if not impossible to place the bonds on the market. So, by the refunding act of July 14, 1870, Congress provided for the payment in "coin of the present standard value," that is to say, in either gold dollars of 25.8 grains of gold, nine-tenths fine, or in silver dollars of 412-1/2 grains of silver, nine-tenths fine, at the option of the United States. But even this extreme advantage to the creditors over payment in "lawful money" of the United States, in which the bonds were bought, and in which they were legally payable, was insufficient. All but the most ingenious would imagine that having thus provided for payment in coin then bearing a considerable premium over the current money of the Republic, and having the very standard of that coin fixed in the act, the highest point of vantage had been reached. One device, however, and only one, remained by which the money of the payment could be still further increased in value, and this device did not escape the watchful eye or cunning hand of the public creditors.
