t, corrected
by frequent observations of longitude and latitude, and to add to the
actual survey of this portion of the river a general map of the country
between the Mississippi and Pacific from the thirty-fourth to the
fifty-fourth degree of latitude. These additions are from information
collected from Indians with whom he had opportunities of communicating
during his journey and residence with them. Copies of this map are now
presented to both Houses of Congress. With these I communicate also a
statistical view, procured and forwarded by him, of the Indian nations
inhabiting the Territory of Louisiana and the countries adjacent to
its northern and western borders, of their commerce, and of other
interesting circumstances respecting them.

In order to render the statement as complete as may be of the Indians
inhabiting the country west of the Mississippi, I add Dr. Sibley's
account of those residing in and adjacent to the Territory of Orleans.

I communicate also, from the same person, an account of the Red River,
according to the best information he had been able to collect.

Having been disappointed, after considerable preparation, in the purpose
of sending an exploring party up that river in the summer of 1804, it
was thought best to employ the autumn of that year in procuring a
knowledge of an interesting branch of the river called the Washita.

This was undertaken under the direction of Mr. Dunbar, of Natchez, a
citizen of distinguished science, who had aided and continues to aid
us with his disinterested and valuable services in the prosecution of
these enterprises. He ascended the river to the remarkable hot springs
near it, in latitude 34 deg. 31' 4.16", longitude 92 deg. 50' 45" west from
Greenwich, taking its courses and distances, and correcting them by
frequent celestial observations. Extracts from his observations and
copies of his map of the river from its mouth to the hot springs make
part of the present communications. The examination of the Red River
itself is but now commencing.

_To the Senate of the United States_:

According to the request of the Senate expressed in their resolution of
3d instant, I now transmit the extract of a letter from the Secretary of
State to the minister plenipotentiary of the United States at Paris, the
answer to that letter, and two letters from Henry Waddell, a citizen of
the United States, relative to the interference of the
