Sir, wherever there is a substantive good to be done, wherever there is a foot of land to be prevented from becoming slave territory, I am ready to assert the principle of the exclusion of slavery. I am pledged to it from the year 1837; I have been pledged to it again and again; and I will perform these pledges; but I will not do a thing unnecessarily that wounds the feelings of others, or that does discredit to my own understanding. * * * Mr. President, in the excited times in which we live, there is found to exist a state of crimination and recrimination between the North and South. There are lists of grievances produced by each; and those grievances, real or supposed, alienate the minds of one portion of the country from the other, exasperate the feelings, and subdue the sense of fraternal affection, patriotic love, and mutual regard. I shall bestow a little attention, sir, upon these various grievances existing on the one side and on the other. I begin with complaints of the South. I will not answer, further than I have, the general statements of the honorable Senator from South Carolina, that the North has prospered at the expense of the South in consequence of the manner of administering this Government, in the collection of its revenues, and so forth. These are disputed topics, and I have no inclination to enter into them. But I will allude to other complaints of the South, and especially to one which has in my opinion, just foundation; and that is, that there has been found at the North, among individuals and among legislators, a disinclination to perform fully their constitutional duties in regard to the return of persons bound to service who have escaped into the free States. In that respect, the South, in my judgment, is right, and the North is wrong. Every member of every Northern legislature is bound by oath, like every other officer in the country, to support the Constitution of the United States; and the article of the Constitution which says to these States that they shall deliver up fugitives from service, is as binding in honor and conscience as any other article. No man fulfils his duty in any legislature who sets himself to find excuses, evasions, escapes from this constitutional obligation. I have always thought that the Constitution addressed itself to the legislatures of the States or to the States themselves. It says that those persons escaping to other States "shall be delivered up," and I confess I have always been of the opinion that it was an injunction upon the States themselves. When it is said that a person escaping into another State, and coming therefore within the jurisdiction of that State, shall be delivered up, it seems to me the import of the clause is, that the State itself, in obedience to the Constitution, shall cause him to be delivered up. That is my judgment. I have always entertained that opinion, and I entertain it now. But when the subject, some years
