says a New England Reviewer, "if we mistake not, but in one instance,
and then in a very light degree, an assessment of direct taxation."

Art. I., sect. 8, says, "Congress shall have power"--among other
things--"to suppress _insurrections_." And Art. IV., sect. 4, says,
"The United States shall guarantee to every State in this Union a
republican form of government; and shall protect each of them against
invasion; and on application of the legislature, or of the executive
(when the legislature cannot be convened), against _domestic
violence_."

These clauses pledge the whole force of the United States' army, and
navy too, if needs be, to the maintenance of slavery in any or in all
the States and Districts in which it may exist. But for this, the
system could not stand a single day. Let the North say to the South,
"We will not interfere with your 'peculiar institution,' but we will
not defend it; if you cannot keep your slaves in subjection, you must
expect no aid from us." Let them only say this, and _do_ nothing, and
the whole fabric of slavery would instantly crumble and fall. The
edifice is rotten, and is propped up only by the buttresses of the
North. The South retains the slave, because the free States furnish the
sentinels.

Again, Art. IV., sect. 2, says, "No person held to service or labour in
one State, under the laws thereof, escaping into another, shall, in
consequence of any law or regulation therein, be discharged from such
service or labour; but shall be _delivered up_ on claim of the party to
whom such service or labour may be due."

This clause pledges the North, not only to refuse an asylum to the
