SIR,--I apprised you in my former letter of the causes which had so long delayed my departure. These still continue. I have this moment received a printed copy of his British Majesty's speech to his Parliament, by which we learn that the preliminaries between Great Britain and America, among which is one for the acknowledgment of our independence, have been provisionally agreed to on his part. That the negotiations with the other powers at war were considerably advanced, and that he hoped, in a very short time, they would end in terms of pacification. As considerable progress has been made in the negotiations for peace since the appointment with which Congress were pleased to honor me, it may have become doubtful whether any communications I could make or any assistance I could yield to the very able gentlemen in whose hands the business already is, would compensate the expense of prosecuting my voyage to Europe. I therefore beg leave through you, Sir, to assure Congress that I desire this question to be as open to them now as it was on the day of my appointment, and that I have not a wish either to go or to stay. They will be pleased to weigh the economy of the one measure against the chance which the other may offer of my arriving in such time as that any communications which have been confided to me may produce effect on definitive articles. I shall continue here for the prosecution of my voyage, under the orders before received, or for its discontinuance, should that be more eligible to Congress, and be signified at any moment before my departure. I have the honor to be, &c. ROBERT R. LIVINGSTON TO THOMAS JEFFERSON. PHILADELPHIA, February 18, 1783. SIR,--I was yesterday honored with your favor of the 14th, which I shall lay before Congress this morning. As you have by this time received their resolution which I had the honor to send you by the last post, and again enclosed, you will be relieved in some measure from your embarrassments, though not entirely of your suspense with respect to their final determination. But that cannot be long doubtful, since the negotiations have certainly arrived at such a crisis as either to terminate soon in a peace or a total rupture. In the latter case, you will necessarily be obliged to proceed on your voyage, as Congress seems anxious to avail themselves of your abilities and information in the negotiations, unless they are fully assured that a speedy peace will preclude them from that advantage. I enclose a paper which contains all that we have yet received on that interesting subject. It may, perhaps, be difficult to account for our ministers having signed before those of France. But if this letter is genuine, it serves, when compared with their instructions, to prove that the terms of peace are acceptable to us and not disagreeable to France. I have the honor to be, Sir, with great respect and esteem, your most obedient, and most humble servant.
