From that day (1830,) SLAVERY, SLAVEHOLDING, SLAVE-BREEDING AND SLAVE-TRADING, HAVE FORMED THE WHOLE FOUNDATION OF THE POLICY OF THE FEDERAL GOVERNMENT, and of the slaveholding States, at home and abroad; and at the very time when a new census has exhibited a large increase upon the superior numbers of the free States, it has presented the portentous evidence of increased influence and ascendancy of the slave-holding power.

Of the prevalence of that power, you have had continual and conclusive evidence in the suppression for the space of ten years of the right of petition, guarantied, if there could be a guarantee against slavery, by the first article amendatory of the Constitution.
