American Constitution, which was formed twelve years afterwards. That Constitution was formed in accordance with the circumstances in which the different states were placed. Its chief object was to guard against external injury, and regulate external affairs; it interfered as little as possible with the internal regulations of each state. The American was a federative system of government; twenty-four distinct republics were united for certain purposes, and for these alone. So far was the national government from possessing unlimited powers, that the Constitution itself was but a very partial grant of those, which, in their omnipotence, resided, according to our theory, only in the people themselves in their primary assemblies. It had been specially agreed in the Constitution itself, that the powers not delegated should be as expressly reserved, as if excepted by name; and, amongst the chief subjects, exclusively interior, and not delegated, and so reserved, is slavery. Had this not been the case, the confederacy could not have been formed. It had been said that the American Constitution had not only tolerated slavery, but that it had actually guaranteed the slave-trade for twenty years. Nothing could be more uncandid than this statement. Never had facts been more perverted. One of the causes of the American Revolution had been the refusal of the British King to sanction certain arrangements on which some of the states wished to enter, for the abolition of the slave-trade. At the formation of the Federal Constitution, while slavery was excluded from the control of Congress, as a purely state affair, the slave trade was deemed a fit subject, by the majority, for the executors of national power, as being an exterior affair. And at a period prior to the very commencement of that great plan of individual effort, guided by Wilberforce and Clarkson, in Britain; and which required twenty years to rouse the conscience of this nation--our distant, and now traduced fathers, had already made up their minds, that this horrid traffic, which they found not only existing, but encouraged by the whole power of the King, should be abolished. It was granted, perhaps too readily to the claims of those who thought, (as nearly the whole world thought) that twenty years should be the limit of the trade; and at the end of that period it was instantly prohibited, as a matter course, and by unanimous consent. How unjust then was it to charge on America, as a crime, what was one of the brightest virtues in her escutcheon. Mr. Thompson had next asserted, that slavery of the most horrid description existed in the Capital of America, and in the surrounding District, subject to the exclusive jurisdiction of Congress. He (Mr. Breckinridge) did not hesitate to deny this. It was not true. Slavery did exist there; but it was not of the horrible character which had been represented. It was well known that the slavery existing in the United States was the mildest to be seen in
