We have said that the slaveholders hold their _own_ laws and Constitutions in the same contempt as those of the Federal Government, whenever they conflict with the security and permanency of slavery. One of the most inestimable of constitutional privileges is TRIAL BY JURY; and this, as we have seen, is trampled under foot with impunity, at the mandate of the slaveholders. Even JOHN TYLER, as it appears, is for inflicting summary punishment on abolitionists, by a Lynch club, "without resorting to any other tribunal." We now proceed to inquire how far they respect the liberty of speech and of the press. IX. LIBERTY OF SPEECH. The whole nation witnessed the late successful efforts of the slaveholders in Congress, by their various gag resolutions, and through the aid of recreant Northern politicians, to destroy all freedom of debate adverse to "the peculiar institution." They were themselves ready to dwell, in debate, on the charms of human bondage; but when a member took the other side of the question, then, indeed, he was out of order, the constitution was outraged, and the Union endangered. We all know the violent threats which have been used, to intimidate the friends of human rights from expressing their sentiments in the national legislature. "As long," says Governor McDuffie to the South Carolina Legislature, "as long as the halls of Congress shall be _open_ to the _discussion_ of this question, we can have neither peace nor security." The Charleston Mercury is, on this subject, very high authority; and in 1837 its editor announced that "Public opinion in the South would now, we are sure, justify an _immediate resort to_ FORCE _by the Southern delegation, even on the_ FLOOR OF CONGRESS, were they forthwith to SEIZE AND DRAG FROM THE HALL any man who dared to insult them, as that eccentric old showman, John Quincy Adams has dared to do." When so much malignity is manifested against the freedom of speech, in the very sanctuary of American liberty, it is not to be supposed that it will be tolerated in the house of bondage. We have already quoted a Southern paper, which declares that the moment "any private individual attempts to lecture us on the evils and immorality of slavery, that very moment his tongue shall be cut out and cast upon the dunghill."
