Agreeably to the appointment, I waited for Count de Florida Blanca, and there, in presence of the French Ambassador, he told me that the King had determined immediately to receive the Envoy from the United States. Our conversation was also very long, and I owe Count de Montmorin the credit to say, that not only at that time, but in every instance where he could operate on the Count de Florida Blanca in our favor, he threw in all the weight of the influence of France.

It was on Wednesday that I received Count de Florida Blanca's visit. In conformity with the Spanish style, he endeavored to delay our affairs. I took the liberty to say, that on Saturday I must set out, and it was at last fixed that on Friday, Mr Carmichael should deliver his credentials, and on Saturday would be invited to the dinner of the foreign Ministers.

As to more important matters, I conversed upon the affair of limits, and upon the navigation of the Mississippi, to the last of which points I found him very repugnant. I spoke upon the codfish duties. I wanted to have a preference engaged for in writing, upon all bargains respecting tobacco and naval stores; in a word, I did my best, and would have been more particular in point of money, had not the Minister's answer put it out of my power to do it in any other way, than such as was inconsistent with the dignity of the United States.

As Count de Florida Blanca was taking leave, I told him that my memory must be somewhat aided. I proposed writing to him, and getting from him an answer. To this he first objected, but afterwards consented, saying, however, that his word was as good as his writing. And as I had been sometimes a little high toned with him in behalf of America, he added, that Spain was sincere in her desire to form an everlasting friendship, but did not act out of fear. I had before observed, that it was on Spain's account that I wished for a good understanding between her and America.

The reading of my letter, a copy of which I enclose, will better inform you of the points that have been either wholly or partially granted. I endeavored to make the best of our conversations, and to engage him as far as I could. On the other hand, I kept our side clear of any engagement, which it was easy for me to do in my private capacity. I did not even go so far as general professions. But since I had been called there, I desired only to induce him into concessions that might serve the purposes of Mr Jay. My letter was delivered on Thursday. The next day I accompanied Mr Carmichael, who is much and universally beloved and respected in that country. On Saturday, before dinner, I received the answer, which for fear of ambiguities, I had requested to be given at the end of the letter. A sentence of the answer I made him explain before the French Ambassador. Herein are joined those copies, and I keep the original for Mr Jay, whose political aid de camp I have thus been. I have of course referred to him everything, and this negotiation, wherein he has exercised the virtue of patience, will now require his care and his abilities. The Ministers of some powers, Prussia among them, having asked me if Congress would be willing to make an advance towards them, I have answered, that the United States ought in my opinion not to make, but to receive advances.

At the same time I was employed in conversation with Count de Florida Blanca, I did not neglect speaking upon the same subject with the other Ministers. M. de Galvez, in whose department the Indies are, appears much averse to the English limit. He has for the present sent orders to the Spanish governors, to abide by those limits, and an official copy of those orders has been promised to me. But M. de Galvez was of opinion, that those limits would not do. I have therefore thought it proper, officially by writing, and before witnesses, so effectually to bind them, that the affair of limits cannot now but be settled on their side. Independent of their hand writing, France, through her Ambassador, is a witness to the engagement; and yet, being in a private capacity, I took care not to engage America to anything.

Never was a man further from a partiality for Spain than I am. But I think I now have left them in a sincere and steady intention to cultivate the friendship of America. The French party at that Court will be for it. They labor under fits of occasional madness. They have an ill conducted pride. It is disagreeable to treat with them, and their own interest does not persuade them out of their prejudices. But though they had rather there were not such a place as North America, they are truly and earnestly desirous to maintain a good harmony and live in friendship and neighborly union with the United States. The Mississippi is the great affair. I think it is the interest of America to be well with Spain, at least for many years; and particularly on account of the French alliance; so that I very much wish success to Mr Jay's negotiations. I have advised Mr Carmichael to continue his conferences, and I think they will be of service.

On my arrival at this city, I hear that Lord Shelburne is out of place, and has been succeeded by Lord North. But I cannot give it as certain. The American flag has already made its appearance before the city of London.

Upon the principles of an unbounded zeal for America, can I be permitted to repeat, that every American patriot must wish that the federal union between the States may continue to receive additional strength? Upon that intimate national union their happiness and their consequence depend.

Hoping that my voluntary excursion to Madrid may have somewhat prepared the way to fulfil the intentions of Congress, I hasten to join Mr Jay, whose abilities will improve the account I shall lay before him.
