From public meetings in the North, the conflict of ideas next extended itself to the floor of Congress, where it continued to rage during nearly thirty years, until "the war of tongue and pen" changed to that of charging squadrons, the storm of shot and the roll of cannon. The question found its way into the debates of Congress in the form of petitions for the abolition of slavery and the slave-trade in the District of Columbia. If the slaveholders had allowed these petitions to be received and referred, taking no notice of them, it seems probable that no important results would have followed. But, blinded by rage and fear, they opposed their reception, thus denying a privilege belonging to all mankind,--that of asking the government to redress their grievances. Then came to the front a man already eminent by his descent, his great attainments, his long public service, his great position, and his commanding ability. John Quincy Adams, after having been President of the United States, accepted a seat in the House of Representatives, and was one of the most laborious and useful of its members. He was not then an Abolitionist, nor in favor even of abolishing slavery in the District of Columbia. But he believed that the people had the right to petition the government for anything they desired, and that their respectful petitions should be respectfully received. Sixty-five years old in 1832, when he began this conflict, his warfare with the slave power ended only when, struck with death while in his seat, he saw the last of earth and was content. With what energy, what dauntless courage, what untiring industry, what matchless powers of argument, what inexhaustible resources of knowledge, he pursued his object, the future historian of the struggle who can fully paint what Mr. Wilson is only able to indicate, will take pleasure in describing. One scene will remain forever memorable as one of the most striking triumphs of human oratory; and this we must describe a little more fully.
