SIR,--Since the receipt of the letter of Monsieur de Calonnes, of October the 22d, 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 _Arret_, which, instead of being revocable by a single letter of a Comptroller General, would require an _Arret_ 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 _Arret_ 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 sea-ports, 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 _Arret_, severally, for their explanation, as well as for the information of Congress.
Article 1. In the course of our conferences with the Comptroller General, we had prevailed on him to pass this article with a suppression of all duty. When he reported the _Arret_, however, to the Council, this suppression was objected to, and it was insisted to re-establish the duties of seven livres and ten sous, and of ten sous the livre, reserved in the letter of M. de Calonnes. The passage of the _Arret_ was stopped, and the difficulty communicated to me. I urged everything I could, in letters and in conferences, to convince them that whale oil was an article which could bear no duty at all. That if the duty fell on the consumer, he would choose to buy vegetable oils; if on the fisherman, he could no longer live by his calling, remaining in his own country; and that if he quitted his own country, the circumstances of vicinity, sameness of language, laws, religion and manners, and perhaps the ties of kindred, would draw him to Nova Scotia, in spite of every encouragement which could be given at Dunkirk; and that thus those fishermen would be shifted out of a scale friendly to France, into one always hostile. Nothing, however, could prevail. It hung on this article alone, for two months, during which we risked the total loss of the _Arret_, on the stability in office of Monsieur Lambert; for if he had gone out, his successor might be less favorable; and if Monsieur Neckar were the successor, we might lose the whole, as he never set any store by us, or the connection with us. About ten days ago, it became universally believed that Monsieur Lambert was to go out immediately. I therefore declined further insisting on the total suppression, and desired the _Arret_ might pass, leaving the duties on whale oil as Monsieur de Calonnes had promised them; but with a reservation, which may countenance our bringing on this matter again, at a more favorable moment.
