On Wednesday, the 3d day of this month, the American Ministers met the British Minister at his lodgings at the _Hôtel de York_, and signed, sealed, and delivered the Definitive Treaty of Peace between the United States of America and the King of Great Britain. Although it is but a confirmation or repetition of the provisional articles, I have the honor to congratulate Congress upon it, as it is a completion of the work of peace, and the best that we could obtain. Nothing remains now to be done but a treaty of commerce; but this in my opinion cannot be negotiated without a new commission from Congress to some one or more persons. Time, it is easy to foresee, will not be likely to render the British nation more disposed to a regulation of commerce favorable to us, and therefore my advice is to issue a commission as soon as may be. There is another subject on which I beg leave to represent to Congress my sentiments, because they seem to me of importance, and because they differ from many sanguine opinions, which will be communicated to the members of that assembly from partisans both of England and France. In the late deliberations concerning an acceptance of the mediation of the Imperial Courts, the British Minister refused it, and in the conferences we had with the Count de Vergennes upon this subject, it was manifest enough to me that he was not fond of our accepting it; for although he maintained a perfect impartiality of language, neither advising us for, nor against the measure, yet at last, when it was observed that Mr Hartley was averse to it, he turned to Dr Franklin and said, that we must agree with Mr Hartley about it, with such a countenance, air, and tone of voice (for from these you must often collect the sentiments of Ministers) as convinced me he did not wish the mediation should take place.
