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° 31' 4.16", longitude 92° 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. TH. JEFFERSON. MARCH 5, 1806. _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 said minister in the case of the ship _New Jersey_ and to the principles alleged to have been laid down on that occasion. There are in the office of the Department of State several printed documents in this case by the agent of those interested in the ship, which are voluminous and in French. If these be within the scope of the request of the Senate, the printed copies can be sent in immediately, but if translations be necessary some considerable time will be requisite for their execution. On this subject any further desire which the Senate shall think proper to express shall be complied with. TH. JEFFERSON. MARCH 7, 1806. _To the Senate of the United States_: According to the request of the Senate of yesterday, I now transmit the five printed memorials of the agent for the ship _New Jersey_, in the one of which marked B, at the ninth page, will be found the letter relative to it from the minister plenipotentiary of the United States at Paris to the French minister of the treasury, supposed to be the one designated in the resolution. We have no information of this letter but through the channel of the party interested in the ship, nor any proof of it more authentic than that now communicated. TH. JEFFERSON. MARCH 19, 1806.
