Gentlemen,

I have received the enclosed letters from M. Dumas since my last of the 22d ultimo, copies of which I sent to Cadiz, to be forwarded in the vessels, that take from thence part of the clothing mentioned in my former letters. The remainder will I hope soon be embarked on board of other vessels, lately arrived in that port from America. As soon as Mr Jay receives the invoices, I will transmit copies thereof to the Committee. I also enclose the last accurate state of the British sea force in Europe. The squadron supposed to be destined for the relief of Gibraltar, sailed the 18th ultimo. The Spanish fleet, of nearly thirty sail of the line, is now at sea to impede their operations, so that important advices are daily expected from the coast. The exact number of the English squadron is not known. Count de Grasse is finally chosen to command the Brest squadron for the American seas, and is by this time nearly ready to sail.

Our affairs are in much the same situation as heretofore. It is not yet known here what part the Empress of Russia will take, although it is generally believed, it cannot be but unfavorable to Great Britain. Mr Cumberland is still here. M. Gardoqui will embark the last of this or first of next month. I make no doubt before his departure, Mr Jay will know the character by which he is to announce him to Congress. I have no reason to believe, that he will not have formal credentials from the Court, for otherwise, notwithstanding the information given in consequence of Mr Jay's conference relative to him with the Minister, I suppose Congress can only regard him as an individual.

A late publication in the Courier de l'Europe, extracted from Rivington's Gazette, asserting a mutiny of a considerable number of continental troops in the beginning of January, made considerable impression here, which happily we have had it in our power to remove by some arrivals from the northward. Considerable apprehensions and jealousies are entertained of the views of the States, of forming powerful establishments on the Ohio and Mississippi, in consequence of some publications in our papers, and other advices received by the Court, which has much better and more regular intelligence of our affairs than Mr Jay. This must be the case as long as the letters of Congress are confided to the common post in France and in this country. The difference of expense could not be so considerable to the public, as might be conceived, and the advantages are important. I am persuaded the Ministers of the above named nations, receive more information from the letters written to the public servants of Congress in Europe, than from those they employ in America. All the couriers of the Empress of Russia are officers of her army. We have at present, I presume, many young men on half pay in consequence of the late arrangements of our army, who would be happy to make these voyages in the public packets, who might be limited or brought to strict account for their expenses, and receive instructions from the Committee to answer public purposes, and be promoted or disgraced according to their execution of them. I beg the Committee will impute these suggestions to the true motive, a regard to the public service.

I have the honor to be, &c.

WILLIAM CARMICHAEL.
