Two precedents for such a proceeding exist in our past history, during the Administration of Mr. Jefferson, to which I would call your attention. On the 26th February, 1803, Congress passed an act appropriating $2,000,000 for the purpose of defraying any extraordinary expenses which may be incurred in the intercourse "between the United States and foreign nations," "to be applied under the direction of the President of the United States, who shall cause an account of the expenditure thereof to be laid before Congress as soon as may be;" and on the 13th February, 1806, an appropriation was made of the same amount and in the same terms. The object in the first case was to enable the President to obtain the cession of Louisiana, and in the second that of the Florida. In neither case was the money actually drawn from the Treasury, and I should hope that the result might be similar in this respect on the present occasion, though the appropriation is deemed expedient as a precautionary measure. I refer the whole subject to the Senate in executive session. If they should concur in opinion with me, then I recommend the passage of a law appropriating such a sum as Congress may deem adequate, to be used by the Executive, if necessary, for the purpose which I have indicated. In the two cases to which I have referred the special purpose of the appropriation did not appear on the face of the law, as this might have defeated the object; neither, for the same reason, in my opinion, ought it now to be stated. I also communicate to the Senate the copy of a letter from the Secretary of State to Commodore Conner of the 29th ultimo, which was transmitted to him on the day it bears date. JAMES K. POLK. WASHINGTON, _August 5, 1846._ _To the Senate and House of Representatives of the United States_: I communicate herewith a copy of a convention for the settlement and adjustment of the Oregon question, which was concluded in this city on the 15th day of June last between the United States and Her Britannic Majesty. This convention has since been duly ratified by the respective parties, and the ratifications were exchanged at London on the 17th day of July, 1846. It now becomes important that provision should be made by law at the earliest practicable period for the organization of a Territorial government in Oregon. It is also deemed proper that our laws regulating trade and intercourse with the Indian tribes east of the Rocky Mountains should be extended to such tribes within our territory as dwell beyond them, and that a suitable number of Indian agents should be appointed for the purpose of carrying these laws into execution. It is likewise important that mail facilities, so indispensable for the diffusion of information and for binding together the different portions of our extended Confederacy, should be afforded to our citizens west of the Rocky Mountains.
