[Sidenote: The idea of a Southern Confederacy.] I know, although the idea has not been stated distinctly, there is to be, or it is supposed possible that there will be, a Southern Confederacy. I do not mean, when I allude to this statement, that any one seriously contemplates such a state of things. I do not mean to say that it is true, but I have heard it suggested elsewhere that the idea has been entertained, that, after the dissolution of this Union, a Southern Confederacy might be formed. I am sorry, Sir, that it has ever been thought of, talked of, or dreamed of, in the wildest flights of human imagination. But the idea, so far as it exists, must be of a separation assigning the slave States to one side and the free States to the other. Sir, I may express myself too strongly, perhaps, but there are impossibilities in the natural as well as in the physical world, and I hold the idea of a separation of these States, those that are free to form one government, and those that are slave-holding to form another, as such an impossibility. We could not separate the States by any such line, if we were to draw it. We could not sit down here to-day and draw a line of separation that would satisfy any five men in the country. There are natural causes that would keep and tie us together, and there are social and domestic relations which we could not break if we would, and which we should not if we could. [Sidenote: Liberty and Union.] Instead of speaking of the possibility or utility of secession, instead of dwelling in those caverns of darkness, instead of groping with those ideas so full of all that is horrid and horrible, let us come out into the light of day; let us enjoy the fresh air of Liberty and Union; let us cherish those hopes which belong to us; let us devote ourselves to those great objects that are fit for our consideration and our action; let us raise our conceptions to the magnitude and the importance of the duties that devolve upon us; let our comprehension be as broad as the country for which we act, our aspirations as high as its certain destiny; let us not be pygmies in a case that calls for men. Never did there devolve on any generation of men higher trusts than now devolve upon us, for the preservation of this Constitution and the harmony and peace of all who are destined to live under it. Let us make our generation one of the strongest and brightest links in that golden chain which is destined, I fondly believe, to grapple the people of all the States to this Constitution for ages to come. We have a great popular, constitutional government, guarded by law and by judicature, and defended by the affections of the whole people. No monarchical throne presses these States together, no iron chain of military power encircles them; they live and stand under a government popular in its form, representative in its character, founded upon principles of equality, and so constructed, we hope, as to last forever. In all its history it
