Gentlemen, Mr Jay having judged it proper for me to reside at this place while the Court remains here, I did not know until his letters for Congress were closed, that Mr Harrison, who charges himself with the care of them to Cadiz, was on the point of setting out from Madrid for that city. This prevented me from assisting him in copying papers, which he tells me he has transmitted by this opportunity. I regret exceedingly, my not having received earlier information, because I wished to convey several papers, which I do not choose to trust to the ordinary post. Our situation in this respect is very disagreeable and delicate, for we can neither send nor receive letters without their being subject to the inspection of others, and, indeed, we have sometimes the mortification to hear of the arrival of letters from America in the sea-ports, which, notwithstanding, never reach us. Our opportunities of information thus become very precarious, and I am much afraid, that the same cause will frequently interrupt our correspondence with Congress. Before Mr Jay arrived in the capital, I did myself the honor to inform his Excellency, the President, of my arrival at Madrid, and enclosed him copies of the letters I wrote to Mr Jay, on the subject of his reception, and of the disposition in which the Court appeared to be. As I sent several copies of these letters, I subjoined all that occurred worthy of the notice of Congress in the interval of the departure of several copies. Not having had any instructions to address myself to Congress, unless in the absence of Mr Jay, or in case of any event that deprived the public of his services, I know not whether I may not appear officious at present; particularly as I have already communicated to him regularly, all the intelligence I have been able to procure, as also my reflections on that intelligence, which his ability and long experience in affairs, will enable him to put in a much clearer point of view than I can pretend to do. If I err, I hope the Committee will set me right, and instruct me how to conduct myself in future. The King, the Prince of Asturias, and the Ministry, appear favorable to our cause, but I am much afraid their ability to assist us in the article of money, is neither equal to our expectations, or their desires to serve us. The papers sent by Mr Jay, will show the sentiments of this Court with respect to the object of his mission. I think the negotiation will be attended with more delay than Congress had reason to apprehend when we left America. This Court manifest a strong desire of excluding every other nation from the navigation of the Mississippi, and indeed of the Gulf of Mexico. The situation of the affairs of America will undoubtedly regulate the conduct of Congress on this subject, and I hope it will be such as to enable them to adhere to the rights of all the States.
