The entire history of the United States is but the record of the evidence of this fact. What event in our annals is there that Slavery has not set her brand upon it to mark it as her own? In the very moment of the nation's birth, like the evil fairy of the nursery tale, she was present to curse it with her fatal words. The spell then wound up has gone on increasing in power, until the scanty formulas which seemed in those days of infancy as if they would fade out of the parchment into which they had been foisted, and leave no trace that they ever were, have blotted out all beside, and statesmen and judges read nothing there but the awful and all-pervading name of Slavery. Once intrenched among the institutions of the country, this baleful power has advanced from one position to another, never losing ground, but establishing itself at each successive point more impregnably than before, until it has us at an advantage that encourages it to demand the surrender of our rights, our self-respect, and our honor. What was once whispered in the secret chamber of council is now proclaimed upon the housetops; what was once done by indirection and guile is now carried with the high hand, in the face of day, at the mouth of the cannon and by the edge of the sabre of the nation. Doctrines and designs which a few years since could find no mouthpiece out of a bar-room, or the piratical den of a filibuster, are now clothed with power by the authentic response of the bench of our highest judicatory, and obsequiously iterated from the oracular recesses of the National Palace.
