roviso: "Sect. 2. Provided, that nothing
herein contained, shall be construed to vest in the United States any
right of property in the soil, or to affect the rights of individuals
_therein_, otherwise than the same shall or may be transferred by such
individuals to the United States."

This specification touching the soil was merely definitive and
explanatory of that clause in the act of cession, "_full and absolute
right_." Instead of restraining the power of Congress on _slavery_ and
other subjects, it even gives it freer course; for exceptions to _parts_
of a rule, give double confirmation to those parts not embraced in the
exceptions. If it was the _design_ of the proviso to restrict
congressional action on the subject of _slavery_, why is the _soil
alone_ specified? As legal instruments are not paragons of economy in
words, might not "John Doe," out of his abundance, and without spoiling
his style, have afforded an additional word--at least a hint--that
slavery was _meant_, though nothing was _said_ about it?

But again, Maryland and Virginia, in their acts of cession, declare them
to be "in pursuance of" that clause of the constitution which gives to
Congress "exclusive legislation in all cases whatsoever over" the ten
miles square--thus, instead of _restricting_ that clause, both States
_confirm_ it. Now, their acts of cession either accorded with that
clause of the constitution, or they conflicted with it. If they
conflicted with it, _accepting_ the cessions was a violation of the
constitution. The fact that Congress accepted the cessions, proves that
in its view their _terms_ did not conflict with its constitutional grant
of power. The inquiry whether these acts of cession were consistent or
inconsistent with the United States' constitution, is totally irrelevant
to the question at issue. What saith the CONSTITUTION? That is the
question. Not, what saith Virginia, or Maryland, or--equally to the
point--John Bull! If Maryland and Virginia had been the authorized
interpreters of the constitution for the Union, these acts of cession
could hardly have been magnified more than they have been recently by
the southern delegation in Congress. A true understanding of the
constitution can be had, forsooth, only by holding it up in the light of
Maryland and Virginia legislation!

We are told, again, that those States would not have ceded the District
if they had supposed the constitution gave Congress power to abolish
