We are called upon to have mercy upon the banks; the prayer should rather be to them, to have mercy upon the government and the people. Since May last the ex-deposit banks alone have forced twenty-five millions of depreciated paper through the federal government upon its debtors and the States, at a loss of at least two and a half millions to the receivers, and a gain of an equal amount to the payers. The thousand banks have the country and the government under their feet at this moment, owing to the community upwards of an hundred millions of dollars, of which they will pay nothing, not even ninepences, picayunes, and coppers. Metaphorically, if not literally, they give their creditors more kicks than coppers. It is for them to have mercy on us. But what is the conduct of government towards these banks? Even at this session, with all their past conduct unatoned for, we have passed a relief bill for their benefit--a bill to defer the collection of the large balance which they still owe the government. But there is mercy due in another quarter--upon the people, suffering from the use of irredeemable and depreciated paper--upon the government, reduced to bankruptcy--upon the character of the country, suffering in the eyes of Europe--upon the character of republican government, brought into question by the successful usurpation of these institutions. This last point is the sorest. Gentlemen speak of the failure of experiments--the failure of the specie experiment, as it is called by those who believe that paper is the ancient and universal money of the world; and that the use of a little specie for the first time is not to be attempted. They dwell upon the supposed failure of "the experiment;" while all the monarchists of Europe are rejoicing in the failure of the experiment of republican government, at seeing this government, the last hope of the liberal world, struck and paralyzed by an oligarchy of banks--seized by the throat, throttled and held as a tiger would hold a babe--stripped of its revenues, bankrupted, and subjected to the degradation of becoming their engine to force their depreciated paper upon helpless creditors. Here is the place for mercy--upon the people--upon the government--upon the character of the country--upon the character of republican government. The apostle of republicanism, Mr. Jefferson, has left it as a political legacy to the people of the United States, never to suffer their government to fall under the control of any unauthorized, irresponsible, or self-created institutions of bodies whatsoever. His allusion was to the Bank of the United States, and its notorious machinations to govern the elections, and get command of the government; but his admonition applies with equal force to all other similar or affiliated institutions; and, since May last, it applies to the whole league of banks which then "shut up the Treasury," and reduced the government to helpless dependence.
