One good private correspondent would be worth twenty committees, made of the wisest heads in America, for the purpose of intelligence. What with clever wives, or pretty girls, or pleasant walks, or too tired, or too busy, or do you do it, very little is done, much postponed, and more neglected. If you are naturally industrious, and love your country, you would frequently take up your pen and your cyphers, and tell me how the wheel of politics runs, and what measures it is from time to time turning out. I should be better informed and Congress better served. I now get more intelligence of your affairs from the French Ambassador, than from all the members of Congress put together. I had written thus far, when I received a letter from M. Le Couteulx at Cadiz, enclosing a letter of the 16th of September, written at St Ildefonso from me to Congress. It had been enclosed in one to Mr Harrison, and that again put under cover to M. Le Couteulx, and, under these two covers, it was put into the post office. Now mark its fate. The Director of the post office at Cadiz showed it to M. Le Couteulx, naked and stripped of its two covers, of which he made no mention. He said it came from Bayonne, but M. Le Couteulx, knowing my hand writing, paid the postage, and returned it to me. This is only one among many instances of the fate to which my letters are subjected. To avoid it, I must now be at the expense of sending Colonel Livingston to the sea-side with my despatches. When at Cadiz, I heard some of our countrymen, who had been prisoners at Lisbon, speak handsomely of M. Dohrmer. They mentioned his having supplied them with necessaries, but at the same time told me that he had been employed for the purpose by Dr Franklin. Hence it happened that I declined mentioning his usefulness to Congress. I considered him as an agent of Dr Franklin, who did his duty faithfully, and thought it would be more proper for him to recommend his services to the notice of Congress than for me. I am, dear Sir, &c. JOHN JAY. * * * * * TO THE PRESIDENT OF CONGRESS. Madrid, November 6th, 1780. Sir, The last particular letter I had the honor of writing to your Excellency was dated the 26th of May, and, with a duplicate, was carried to Cadiz by Mr Harrison, who sent one by the Peacock, Captain Davis, to Boston, and the other by the General Arnold, Captain Jenkins, to Alexandria in Virginia. They both sailed in June last, and the former, I hear, arrived safe after a short passage. I have since written several letters to your Excellency, but as they went to the seaports by the post, none of them contained anything material, except one from St Ildefonso of the 16th of September, advising Congress of the necessity of suspending further drafts on me for the present.
