asters claim compensation of the government?
Manifestly not; even though no proof existed that the particular slaves
killed were insurgents. This was precisely the point at issue between
those masters, whose slaves were killed by the State troops at the time
of the Southampton insurrection, and the Virginia Legislature: no
evidence was brought to show that the slaves killed by the troops were
insurgents; yet the Virginia Legislature decided that their masters were
_not entitled to compensation_. They proceeded on the sound principle,
that a government may in self-protection destroy the claim of its
subjects even to that which has been recognized as property by its own
acts. If in providing for the common defence, the United States'
government, in the case supposed, would have power to destroy slaves
both as _property_ and _persons_, it surely might stop _half-way_,
destroy them _as property_ while it legalized their existence as
_persons_, and thus provided for the common defence by giving them a
personal and powerful interest in the government, and securing their
strength for its defence.

Like other Legislatures, Congress has power to abate nuisances--to
remove or tear down unsafe buildings--to destroy infected cargoes--to
lay injunctions upon manufactories injurious to the public health--and
thus to "provide for the common defence and general welfare" by
destroying individual property, when such property puts in jeopardy the
public weal.

Granting, for argument's sake, that slaves are "property" in the
District of Columbia--if Congress has a right to annihilate property in
the District when the public safety requires it, it may surely
annihilate its existence _as_ property when the public safety requires
it, especially if it transform into a _protection_ and _defence_ that
which as _property_ perilled the public interests. In the District of
Columbia there are, besides the United States' Capitol, the President's
house, the national offices, &c. of the Departments of State, Treasury,
War, and Navy, the General Post-office, and Patent Office. It is also
the residence of the President, all the highest officers of the
government, both houses of Congress, and all the foreign ambassadors. In
this same District there are also _seven thousand slaves_. Jefferson, in
his Notes on Va. p. 241, says of slavery, that "the State permitting one
half of its citizens to trample on the rights of the other, _transforms
them into enemi
