You know that the merchants of New York and Philadelphia were of opinion that a public vessel sent into the Bay of Bengal to notify our trade there, would in fact increase the danger of our vessels. The most intelligent merchants of Baltimore, consulted by Mr. Smith, were of the same opinion as to the Straits of Sunda. It was therefore concluded between Mr. Smith, Mr. Madison, and myself, (time not admitting further consultation,) that it would be best to make a Consul for Batavia, (there being none,) and send him to his post by a private vessel, with instructions to take the best measures he could for notifying all our trade beyond the Straits, to instruct our Consul at the Isle of France to do the same to all on this side, and moreover to send a special agent by any private conveyance to be obtained, to go from port to port in the Bay of Bengal, to give private notice to the vessels there. As several vessels were on their departure for those seas from Philadelphia and Baltimore, it is trusted that this arrangement will effect all the good proposed, and avoid all the evil apprehended at the different places which were consulted. I set out to-morrow to Bedford, and shall be absent eight days. I shall leave this on the 30th, and be in Washington the 3d of October, ready for our meeting on the 5th. I salute you affectionately. TO GOVERNOR CABELL. MONTICELLO, September 18, 1807. SIR,--On my return to this place yesterday I found your favor of the 15th, and now return the papers it covered. I am glad to see the temperate complexion of Lowrie's correspondence. I presume the intelligence from England since the arrival there of the information respecting the Chesapeake, will produce a moderate deportment in their officers. Your instructions to Major Newton on the opening of letters, are perfectly consonant with the rules laid down. With respect to the mode of furnishing the troops with provisions through any other channel than that of the public contractor, I am unable to say anything, being not at all acquainted with the arrangements of the war department on that subject. I enclose you a letter I have received from a Mr. Belcher, of Gloster, giving reason to believe there have been some contraventions of the Proclamation there which ought to be punished if they can be detected. I salute you with great esteem and respect. TO MR. MADISON. MONTICELLO, September 18, 1807.
