Since the receipt of the letter of Monsieur de Calonne, of October the 22nd, 1786, I have several times had the honor of mentioning to you, that I was endeavoring to get the substance of that letter reduced into an _Arrêt_, which, instead of being revocable by a single letter of a Comptroller General, would require an _Arrêt_ to repeal or alter it, and of course must be discussed in full Council, and so give time to prevent it. This has been pressed as much as it could be with prudence. One cause of delay has been the frequent changes of the Comptroller General; as we had always our whole work to begin again, with every new one. Monsieur Lambert’s continuance in office for some months has enabled us, at length, to get through the business; and I have just received from him a letter, and the _Arrêt_ duly authenticated; of which I have the honor to send you a number of printed copies. You will find, that the several alterations and additions are made, which, on my visit, to the seaports, I had found to be necessary, and which my letters of June the 21st and August the 6th particularly mentioned to you. Besides these, we have obtained some new articles of value, for which openings arose in the course of the negotiation. I say we have done it, because the Marquis de la Fayette has gone hand in hand with me through this business, and has been a most invaluable aid. I take the liberty of making some observations on the articles of the _Arrêt_, severally, for their explanation, as well as for the information of Congress.
