invasion? If the national government had exercised its constitutional
"power to provide for the common defence and to promote the general
welfare," by turning those "enemies" into friends, then, instead of a
hostile ambush lurking in every thicket inviting assault, and secret
foes in every house paralyzing defence, an army of allies would have
rallied in the hour of her calamity, and shouted defiance from their
munitions of rocks; whilst the banner of the republic, then trampled in
dust, would have floated securely over FREEMEN exulting amidst bulwarks
of strength.

To show that Congress can abolish slavery in the District, under the
grant of power "to provide for the common defence and to promote the
general welfare," I quote an extract from a speech of Mr. Madison, of
Va., in the first Congress under the constitution, May 13, 1789.
Speaking of the abolition of the slave trade, Mr. Madison says: "I
should venture to say it is as much for the interests of Georgia and
South Carolina, as of any state in the union. Every addition they
receive to their number of slaves tends to _weaken_ them, and renders
them less capable of self-defence. In case of hostilities with foreign
nations, they will be the means of _inviting_ attack instead of
repelling invasion. It is a necessary duty of the general government to
protect every part of the empire against danger, as well _internal_ as
external. _Every thing, therefore, which tends to increase this danger,
though it may be a local affair, yet if it involves national expense or
safety, it becomes of concern to every part of the union, and is a
proper subject for the consideration of those charged with the general
administration of the government._" Cong. Reg. vol. 1, p. 310, 11.
