I have already amply shown to-day that Slavery is in no respect national--that it is not within the sphere of national activity,--that it has no "positive" support in the Constitution,--and that any interpretation inconsistent with this principle would be abhorrent to the sentiments of its founders. Slavery is a local institution, peculiar to the States, and under the guardianship of State rights. It is impossible, without violence to the spirit and letter of the Constitution, to claim for Congress any power to legislate either for its abolition in the States or its support anywhere. Non-Intervention is the rule prescribed to the nation. Regarding the question in its more general aspects only, and putting aside, for the moment, the perfect evidence from the records of the convention, it is palpable that there is no national fountain out of which the existing Slave Act can possibly spring. But this Act is not only an unwarrantable assumption of power by the nation, it is also an infraction of rights reserved to the States. Everywhere within their borders the States are peculiar guardians of personal liberty. By jury and habeas corpus to save the citizen harmless against all assault is among their duties and rights. To his State the citizen, when oppressed, may appeal; nor should he find that appeal denied. But this Act despoils him of rights, and despoils his State of all power to protect him. It subjects him to the wretched chance of false oaths, forged papers, and facile commissioners, and takes from him every safeguard. Now, if the slaveholder has a right to be secure at home in the enjoyment of Slavery, so also has the freeman of the North--and every person there is presumed to be a free man--an equal right to be secure at home in the enjoyment of freedom. The same principle of State rights by which Slavery is protected in the slave States throws an impenetrable shield over Freedom in the free States. And here, let me say, is the only security for Slavery in the slave States, as for Freedom in the free States. In the present fatal overthrow of State rights you teach a lesson which may return to plague the teacher. Compelling the National Government to stretch its Briarean arms into the free States for the sake of Slavery, you show openly how it may stretch these same hundred giant arms into the slave States for the sake of Freedom. This lesson was not taught by our fathers. Here I end this branch of the question. The true principles of our political system, the history of the National Convention, the natural interpretation of the Constitution, all teach that this Act is a usurpation by Congress of powers that do not belong to it, and an infraction of rights secured to the States. It is a sword, whose handle is at the National Capital, and whose point is everywhere in the States. A weapon so terrible to personal liberty the nation has no power to grasp. (2). And now of the denial of Trial by Jury.
