III
The vessels and citizens of the French Republic may exercise
commerce to and at such places on their respective shores
below the said thirty first degree of North Latitude as may
be allowed for that use by the parties to their respective citizens
and vessels. And it is agreed that no other Nation shall
be allowed to exercise commerce to or at the same or any other
place on either shore, below the said thirty first degree of Latitude.
For the term of ten years to be computed from the
exchange of the ratifications hereof, the citizens, vessels and
merchandizes of the United States and of France shall be subject
to no other duties on their respective shores below the
said thirty first degree of latitude than are imposed on their
own citizens, vessels and merchandizes. No duty whatever
shall, after the expiration of ten years be laid on Articles the
growth or manufacture of the United States or of the ceded
Territory exported thro' the Mississippi in French vessels, so
long as such articles so exported in vessels of the United
States shall be exempt from duty: nor shall French vessels
exporting such articles, ever afterwards be subject to pay a
higher duty than vessels of the United States.
