before mentioned; while, in the States in which they respectively
reside, the abolitionists feel it to be their duty to exert themselves,
to wipe away from the statute book every vestige of that barbarism which
makes political, civil, or religious rights depend upon the color of the
skin.

Yet more important is it, however, to bring the moral force of the North
to bear against slavery, by reforming the prevailing public sentiment of
the religious, moral, and intelligent portion of the community. Here
again, one of the most sagacious leaders of the pro-slavery party, J.C.
Calhoun, has descried the danger from afar, and has publicly proclaimed
it in the senate of the United States, by vehemently deprecating the
anti-slavery proceedings, not as intended to provoke the slaves to a
servile war, but as a crusade against the _character_ of the
slave-holders.

Although the different States are distinct governments, their
geographical boundaries are mere lines upon the map; their inhabitants
speak the same language, and enjoy a communion of citizenship all over
the Union. The North Eastern States have by far the greater part of the
whole commerce of the Union, and are the medium through which the
planter exchanges his cotton for provisions and clothing for his slaves,
implements for his agriculture, and his own family supplies. These
commercial ties create a direct and extensive pro-slavery interest in
the North. Again, the planter is yet more dependent on the North for
education for his children, and for the gratification of his own
intellectual wants, as the slave-holding region has few colleges, and
those of secondary reputation; while I believe it has no periodical of
higher pretension than the political newspapers. The pro-slavery
re-action in this way, on the seminaries of the North, and on the
literature of the United States, is most sensibly felt.

Another powerful cause that contributes to leaven the entire population
into one mind on the subject of slavery, is the double migration that
annually takes place of people of the Southern States to the North, in
summer, and of the inhabitants of the free States to the South in
winter. Hence follow family alliances, the interchange of hospitalities,
and a fusion of sentiments, so that the slavery interest spreads its
countless ramifications through every corner of the free north.

Another cause, and perhaps the most powerful of all, is the community of
