DEAR SIR,--Yours of the 10th came to hand yesterday, and I return you Fronda's, Tuft's, Loderstrom's, and Turreau's letters. I think it is become necessary to let Turreau understand explicitly that the vessels we permit foreign ministers to send away are merely transports, for the conveyance of such of their subjects as were here at the time of the embargo; that the numbers must be proportioned to the vessels, as is usual with transports; and that all who meant to go away must be presumed to have gone before now,--at any rate, that none will be accommodated after the present vessel. We never can allow one belligerent to buy and fit out vessels here, to be manned with his own people, and probably act against the other. You did not return my answer to Sullivan. But fortunately I have received another letter, which will enable me to give the matter an easier turn, and let it down more softly. Should the conference announced in Mr. Pinckney's letter of June 5th, settle friendship between England and us, and Bonaparte continue at war with Spain, a moment may occur favorable, without compromitting us with either France or England, for seizing our own from the Rio Bravo to Perdido, as of right, and the residue of Florida, as a reprisal for spoliations. I have thought it proper to suggest this possibility to General Dearborne and Mr. Smith, and to recommend an eye to it in their rendezvousing and stationing the new southern recruits and gun-boats, so that we may strike in a moment when Congress says so. I have appointed General Steele successor to Shee. Mr. and Mrs. Barlow, and Mrs. Blayden, will be here about the 25th. May we hope to see Mrs. Madison and yourself then, or when? I shall go to Bedford about the 10th of September. I salute you with constant affection and respect. TO HIS EXCELLENCY GOVERNOR SULLIVAN. MONTICELLO, August 12, 1808. SIR,--Your letter of July 21st has been received some days; that of July 23d not till yesterday. Some accident had probably detained it on the road considerably beyond its regular passage. In the former you mention that you had thought it advisable to continue issuing certificates for the importation of flour, until you could hear further from me; and in the latter, that you will be called from the Capital in the fall months, after which it is your desire that the power of issuing certificates may be given to some other, if it is to be continued.
