DEAR SIR,--I received on the 20th your favor of the 10th instant, and yesterday I wrote to desire the Secretary of State to forward your passport to Elizabethtown. In the visit you propose to make to your native country, I sincerely wish you may find its situation, and your own interests in it, satisfactory. On what it has been, is, or shall be, however, I shall say nothing. I consider Europe, at present, as a world apart from us, about which it is improper for us even to form opinions, or to indulge any wishes but the general one, that whatever is to take place in it, may be for its happiness. For yourself, however, personally, I may express with safety as well as truth, my great esteem and the interest I feel for your welfare. From the same principles of caution, I do not write to my friend Kosciusko. I know he is always doing what he thinks is right, and he knows my prayers for his success in whatever he does. Assure him, if you please, of my constant affection, and accept yourself my wishes for a safe and pleasant voyage, with my friendly salutations and assurances of great esteem and respect. TO MR. MADISON. MONTICELLO, April 25, 1807. DEAR SIR,--Yours of the 20th came to hand on the 23d, and I now return all the papers it covered, to wit, Harris's, Maunce's, and General Smith's letters, as also some papers respecting Burr's case, for circulation. Under another cover is a letter from Governor Williams, confidential, and for yourself alone, as yet. I expect we shall have to remove Meade. Under still a different cover you will receive Monroe's and Pinckney's letters, detained at the last post. I wrote you then on the subject of the British treaty, which the more it is developed the worse it appears. Mr. Rodney being supposed absent, I enclose you a letter from Mr. Reed, advising the summoning Rufus Easton as a witness; but if he is at St. Louis, he cannot be here by the 22d of May. You will observe that Governor Williams asks immediate instructions what he shall do with Blennerhasset, Tyler, Floyd, and Ralston. I do not know that we can do anything but direct General Wilkinson to receive and send them to any place where the judge shall decide they ought to be tried. I suppose Blennerhasset should come to Richmond. On consulting with the other gentlemen, be so good as to write to Williams immediately, as a letter will barely get there by the 4th Monday of May. I enclose you a warrant for five thousand dollars for Mr. Rodney, in the form advised by Mr. Gallatin. We have had three great rains within the last thirteen days. It is just now clearing off after thirty-six hours of rain, with little intermission. Yet it is thought not too much. I salute you with sincere affection. TO MR. THOMAS MOORE. MONTICELLO, May 1,1807.
