1. Looking to the men who formed it, and who lead it, the platform on which it stands, and the end which it contemplates, I regard the organization headed by Breckinridge and Lane as essentially a sectional slavery extension party, bound through the Federal judiciary, backed by the Federal government, to extend slavery into all the territories of the United States, with or without the assent of the people, and if need be to accomplish this end, bound to legalize slavery under the Federal Constitution in every State of the Union, and to open the floodgates of the African slave trade under the protection of the national banner. This is the logical end of the Breckinridge and Lane platform. Its practical end will be the destruction of the American Union, for no man in his senses can believe that the Federal government, either through its President, or its Congress, or its Supreme Court, can ever make negro slavery lawful for one hour, where the free white people of any State will that it shall not be. If slaveholders are ever to reach the throne of national power on this continent, which the Breckinridge party are aiming to erect for them, they will wade to that throne through battle fields flowing with human blood. This Breckinridge and Lane party holds within its bosom the rankest disunionists and most ultra advocates of the African slave trade. Its true watch cry, whatever it may pretend in the North, is "_National Slavery or Disunion_." With this view of the Breckinridge party, I cannot therefore say that I admired the good taste or consistency of my Republican friends, when in this city a few nights ago, they encouraged by loud applause, the virulent harangue of Jesse D. Bright, the Indiana leader of the Breckinridge faction, not I presume because they approved his sentiments, but because he abused Stephen A. Douglas.
