DEAR SIR,--Yours of July 27th has been received. I now enclose you the letters of Hawkins, Harrison, Wells, Hull, and Claiborne, received from the war office, and as I conjecture, not yet seen by you. Indian appearances, both in the northwest and south, are well. Beyond the Mississippi they are not so favorable. I fear Governor Lewis has been too prompt in committing us with the Osages so far as to oblige us to go on. But it is astonishing we get not one word from him. I enclose you letters of Mr. Griff and Maclure, which will explain themselves. A letter of June 5th from Mr. Pinckney, informs us he was to have a free conference with Canning in a few days. Should England make up with us, while Bonaparte continues at war with Spain, a moment may occur when we may without danger of commitment with either France or England seize to our own limits of Louisiana as of right, and the residue of the Floridas as reprisal for spoliations. It is our duty to have an eye to this in rendezvousing and stationing our new recruits and our armed vessels, so as to be ready, if Congress authorizes it, to strike in a moment. I wish you to consider this matter in the orders to the southern recruits, as I have also recommended to the Secretary of the Navy, as to the armed vessels in the South. Indeed, I would ask your opinion as to the positions we had better take with a view to this with our armed vessels as well as troops. The force in the neighborhood of Baton Rouge is enough for that. Mobile, Pensacola and St. Augustine, are those we should be preparing for. The enforcing the embargo would furnish a pretext for taking the nearest healthy position to St. Mary's, and on the waters of Tombigbee. I salute you with affection and respect. TO THE SECRETARY OF STATE. MONTICELLO, August 12, 1808.
