in the case of injuries, as may be competent to the purpose.
The right must extend to all those objects, or it will be utterly
incompetent. It is possessed and exercised by the States individually,
and it must be possessed by the United States or the pretension must be
abandoned.

Let it be further supposed that Congress, believing that they do
possess the power, have passed an act for those purposes, under which
commissioners have been appointed, who have begun the work. They are met
at the first farm on which they enter by the owner, who forbids them
to trespass on his land. They offer to buy it at a fair price or at
twice or thrice its value. He persists in his refusal. Can they, on the
principle recognized and acted on by all the State governments that in
cases of this kind the obstinacy and perverseness of an individual must
yield to the public welfare, summon a jury of upright and discreet men
to condemn the land, value it, and compel the owner to receive the
amount and to deliver it up to them? I believe that very few would
concur in the opinion that such a power exists.

The next object is to preserve these improvements from injury. The locks
of the canal are broken, the walls which sustained the road are pulled
down, the bridges are broken, the road itself is plowed up, toll is
refused to be paid, the gates of the canal or turnpike are forced.
The offenders are pursued, caught, and brought to trial. Can they
be punished? The question of right must be decided on principle. The
culprits will avail themselves of every barrier that may serve to screen
them from punishment. They will plead that the law under which they
stand arraigned is unconstitutional, and that question must be decided
by the court, whether Federal or State, on a fair investigation of the
powers vested in the General Government by the Constitution. If the
judges find that these powers have not been granted to Congress, the
prisoners must be acquitted, and by their acquittal all claim to the
right to establish such a system is at an end.

I have supposed an opposition to be made to the right in Congress by the
owner of the land and other individuals charged with breaches of laws
made to protect the works from injury, because it is the mildest form in
which it can present itself. It is not, however, the only one. A State,
also, may contest the right, and then the controversy assumes another
character. Government might contend against government,
