SIR,--This will be handed you by Colonel Blackden, heretofore an officer in the American army--at present engaged in trade. He goes to Honfleur with a view to examine the commercial relations which may be established between that port and the United States. He wishes particularly to see the nature of its harbor, the conveniences already established for commerce, and to know something of the productions which can be taken and given there in exchange. Knowing your desire to assist in drawing the American commerce to that port, I take the liberty of recommending this gentleman to your acquaintance, and of praying you to procure him the information he desires. Some late regulations of the King and Council in favor of the commerce of the United States having given us room to hope that our endeavors may be successful to remove a good part of it from Great Britain to France, Honfleur presents itself as a more important instrument for this purpose than it had heretofore appeared. We are, therefore, now pressing more earnestly its establishment as a free port, and such other regulations in its favor as may invite the commerce to it. I have the honor to be, Sir, your most obedient, and most humble servant. TO THE HONORABLE MR. JAY. PARIS, November 12, 1786. SIR,--In a letter which I had the honor of writing you on the 26th of September, I informed you that a Dutch company were making propositions to the Minister of Finance here to purchase at a discount, the debt due from the United States to this country. I have lately procured a copy of their memoir which I now enclose. Should Congress think this subject worthy their attention, they have no time to lose, as the necessities of the minister, which alone has made him listen to this proposition, may force him to a speedy conclusion. The effect which a payment of the whole sum would have here, would be very valuable. The only question is, whether we can borrow it in Holland, a question which cannot be resolved but in Holland. The trouble of the trial, and the expense of the transaction, would be well repaid by the dispositions which would be excited in our favor in the King and his ministers. I have the honor to be, with sentiments of the most perfect esteem and respect, Sir, your most obedient, and most humble servant. M. LE ROY DE L'ACADEMIE DES SCIENCES. PARIS, November 13, 1786. SIR,--I received the honor of yours of September the 18th, a day or two after the accident of a dislocated wrist had disabled me from writing. I have waited thus long in constant hope of recovering its use. But finding that this hope walks before me like my shadow, I can no longer oppose the desire and duty of answering your polite and learned letter. I therefore employ my left hand in the office of scribe, which it performs indeed slowly, awkwardly and badly.
