I had the honor of addressing you on the 27th ult., since which letters are received of January 24th, from Mr. Carmichael, and of January 3d and 15th, Madrid, and February 6th, and 12th, Lisbon, from Colonel Humphreys. As these are interesting, and may tend to settle suspense of mind to a certain degree, I shall trouble you with quotations from some parts and the substance of others.

Colonel H. says, "I learn from other good authority, as well as from Mr. Carmichael, that all the representations of Gardoqui (when minister in America), tended to excite a belief that the most respectable and influential people throughout the United States did not wish to have the navigation of the Mississippi opened for years to come, from an apprehension such an event would weaken the government, and impoverish the Atlantic States by emigrations. It was even pretended that none but a handful of settlers on the Western waters, and a few inhabitants of the Southern States would acquiesce in the measure." This is the state of mind to which they have reverted since the crisis with England is passed, for during that, the Count de Florida Blanca threw out general assertions that we should have no reason to complain of their conduct with respect to the Mississippi, which gave rise to the report its navigation was opened. The following passages will be astonishing to you who recollect that there was not a syllable in your letters to Mr. G. M., which looked in the most distant manner to Spain. Mr. Carmichael says, "something, however, might have been done in a moment of projects and apprehension, had not a certain negotiation carried on, on our part, at London, transpired, and which I think was known here rather from British policy, than from the vigilance of the Marquis del Campo. Entirely unacquainted with this manœuvre, although in correspondence with the person employed, I was suspected to be in the secret. This suspicion banished confidence, which returns by slow degrees. This circumstance induced me to drop entirely my correspondence with G. M. To continue it would have done harm, and certainly could do no good. I have seen extracts of the President's letter communicated to the Duke of Leeds, perhaps mutilated or forged to serve here the views of the British cabinet. I do not yet despair of obtaining copies of those letters through the same channel that I procured the first account of the demands of G. B. and the signature of the late convention." Colonel Humphreys says, "the minister had intimations from del Campo of the conferences between Mr. Morris and the Duke of Leeds, which occasioned him to say with warmth to Mr. Carmichael, 'now is your time to make a treaty with England.' Fitzherbert availed himself of these conferences to create apprehensions that the Americans would aid his nation in case of war." Your genuine letter could have made no impression. The British court then must have forged one, to suit their purpose, and I think it will not be amiss to send a genuine copy to Carmichael, to place our faith on its just ground. The principal hope of doing anything now, is founded either on an expected removal of the Count de F. B. from the ministry, in which case persons will be employed who are more friendly to America, or to the bursting out of that fire which both gentlemen think but superficially covered. Mr. Carmichael justifies himself by the interception of his letters. He has shown the originals to Colonel H. He concludes his present letter with these words, "relying on the good opinion of me, that you have been pleased to express on many occasions, I intreat you to engage the President to permit me to return to my native country." Colonel Humphreys, on the subjects of his justification and return says, (after speaking of the persons likely to come into power,) "Mr. Carmichael being on terms of intimacy with the characters here, is certainly capable of effecting more at this court than any other American. He is heartily desirous of accomplishing the object in view at all events, and fully determined to return to America in twelve or eighteen months at farthest. He has expressed that intention repeatedly. To be invested with full powers, perhaps he would be able to do something before his departure from the continent." In his letter of January 15th, he says, "Mr. Carmichael's ideas are just: his exertions will be powerful and unremitting to obtain the accomplishment of our desires before his departure from this country. The task will now be difficult if not impracticable." In that of February 6th, he says, "Mr. Carmichael is much mortified that so many of his despatches have miscarried. By the original documents, which I have seen in his hands, I am convinced he has been extremely assiduous and successful in procuring early and authentic intelligence. It is difficult for a person at a distance to form an adequate judgment of the embarrassments to which a public man, situated as he was, is subjected, in making written communications, from such an inland place, and under such a jealous government. He appears disgusted with the country and the mode of life he is compelled to lead. He desires ardently to return to his native land; but he wishes to distinguish himself first by rendering some essential service to it if possible."

Governor Quesada, by order of his court, is inviting foreigners to go and settle in Florida. This is meant for our people. Debtors take advantage of it, and go off with their property. Our citizens have a right to go where they please. It is the business of the States to take measures to stop them till their debts are paid. This done, I wish a hundred thousand of our inhabitants would accept the invitation. It will be the means of delivering to us peaceably what may otherwise cost us a war. In the meantime, we may complain of this seduction of our inhabitants just enough to make them believe we think it very wise policy for them, and confirm them in it. This is my idea of it. I have the honor to be, with sentiments of the most perfect respect and attachment, Sir, your most obedient, and most humble servant.


TO MAJOR L'ENFANT.

Philadelphia, April 10, 1791.

Sir,—I am favored with your letter of the 4th instant, and in compliance with your request, I have examined my papers, and found the plans of Frankfort-on-the-Mayne, Carlsruhe, Amsterdam, Strasburg, Paris, Orleans, Bordeaux, Lyons, Montpelier, Marseilles, Turin, and Milan, which I send in a roll by the post. They are on large and accurate scales, having been procured by me while in those respective cities myself. As they are connected with the notes I made in my travels, and often necessary to explain them to myself, I will beg your care of them, and to return them when no longer useful to you, leaving you absolutely free to keep them as long as useful. I am happy that the President has left the planning of the town in such good hands, and have no doubt it will be done to general satisfaction. Considering that the grounds to be reserved for the public are to be paid for by the acre, I think very liberal reservations should be made for them; and if this be about the Tyber and on the back of the town, it will be of no injury to the commerce of the place, which will undoubtedly establish itself on the deep waters towards the eastern branch and mouth of Rock Creek; the water about the mouth of the Tyber not being of any depth. Those connected with the government will prefer fixing themselves near the public grounds in the centre, which will also be convenient to be resorted to as walks from the lower and upper town. Having communicated to the President, before he went away, such general ideas on the subject of the town as occurred to me, I make no doubt that, in explaining himself to you on the subject, he has interwoven with his own ideas, such of mine as he approved. For fear of repeating therefore what he did not approve, and having more confidence in the unbiassed state of his mind, than in my own, I avoided interfering with what he may have expressed to you. Whenever it is proposed to prepare plans for the Capitol, I should prefer the adoption of some one of the models of antiquity, which have had the approbation of thousands of years; and for the President's house, I should prefer the celebrated fronts of modern buildings, which have already received the approbation of all good judges. Such are the Galerie du Louire, the Gardes meubles, and two fronts of the Hotel de Salm. But of this it is yet time enough to consider. In the meantime I am, with great esteem, Sir, your most obedient humble servant.


TO THE PRESIDENT OF THE UNITED STATES.

Philadelphia, April 10, 1791.
