It is now proposed to set aside this Prohibition. But there seems to be a singular indecision as to the way in which the deed shall be done. From the time of its first introduction, in the Report of the Committee on Territories, the proposition has assumed different shapes; and it promises to assume as many as Proteus,--now one thing in form, and now another,--now like a serpent, and then like a lion,--but in every form and shape identical in substance; with but one object,--the overthrow of the Prohibition of Slavery. At first it proposed simply to declare that the States formed out of this territory should be admitted into the Union "with or without Slavery," and did not directly assume to touch this Prohibition. For some reason this was not satisfactory, and then it was precipitately proposed to declare that the Prohibition in the Missouri Act "was superseded by the principles of the legislation of 1850, commonly called the Compromise Measures, and is hereby declared inoperative." But this would not do; and it is now proposed to enact, that the Prohibition, "being inconsistent with the principles of non-intervention by Congress with Slavery in the States and Territories, as recognized by the legislation of 1850, commonly called the Compromise Measures, is hereby declared inoperative and void." * * * * * All this is to be done on pretences founded upon the Slavery enactments of 1850. Now, Sir, I am not here to speak in behalf of those measures, or to lean in any way upon their support. Relating to different subject-matters, contained in different acts, which prevailed successively, at different times, and by different votes,--some persons voting for one, and some for another, and very few for all,--they cannot be regarded as a unit, embodying conditions of compact, or compromise, if you please, adopted equally by all, and therefore obligatory on all. But since this broken series of measures is adduced as apology for the proposition now before us, I desire to say, that, such as they are, they cannot, by any rule of interpretation, by any charming rod of power, by any magic alchemy, be transmuted into a repeal of that original Prohibition.
