US Presidency
1844

In sanctioning a bill of the same title with that returned, for the improvement of the Mississippi and its chief tributaries and certain harbors on the Lakes, if I bring myself apparently in conflict with any of the principles herein asserted it will arise on my part exclusively from the want of a just appreciation of localities. The Mississippi occupies a footing altogether different from the rivers and water courses of the different States. No one State or any number of States can exercise any other jurisdiction over it than for the punishment of crimes and the service of civil process. It belongs to no particular State or States, but of common right, by express reservation, to all the States. It is reserved as a great common highway for the commerce of the whole country.
