_To the House of Representatives of the United States_:
In compliance with a resolution of the House of Representatives of the
13th instant, requesting the President to communicate any information
he may possess in relation to the intercourse and trade now carried on
between the people of the United States (and particularly the people
of the State of Missouri) and the Mexican Provinces, how and by what
route that trade or intercourse is carried on, in what it consists, the
distances, etc., the nations of Indians through which it passes, their
dispositions, whether pacific or otherwise, the advantages resulting or
likely to result from that trade or intercourse, I herewith transmit
a communication from the Department of State, which contains all the
information which has yet been collected in relation to those subjects.
