LEGATION OF THE UNITED STATES, ST. PETERSBURG, July 31, N. S. 1833. On Friday last, the 28th instant, I had an interview with Count Nesselrode, for the purpose of making the necessary arrangements previous to my departure from this country. After the usual salutations, he introduced the subject of the commercial treaty, which is one of his favorite topics. The opposition made to it in the imperial council, and the difficulties which he there encountered and overcame, seem to have inspired him with a feeling of paternity towards this treaty. After some general conversation, relating chiefly to its favorable reception in the United States, I changed the subject, and remarked, that in our last interview I had entirely forgotten to mention that his explanation in regard to Baron Sacken’s note was entirely satisfactory to the President. It might be proper to observe, however, that Mr. Livingston differed materially from the baron in relation to some of the facts attending this unpleasant transaction, and it had, at first, been my intention to bring these points of difference specially under the notice of his excellency; but after reflection, I had determined that it was best upon the whole not to revive the subject. He immediately replied it was wholly unnecessary; he wished the whole subject to be buried in oblivion and there remain as if it had never existed. He expressed his pleasure in the strongest terms that the President was satisfied with the explanation, and then laughingly observed that Baron Sacken and Mr. Livingston were now both _hors du combat_: the one was no longer chargé nor the other Secretary of State. I felt the less inclined to enter into any detail upon this subject, as Mr. Livingston admits that Baron Sacken did show him the offensive note at New York, and _that he did not make any objections to its style_, though he is convinced this took place after the note had been sent to Mr. Brent and not before, as the baron had informed Count Nesselrode. When I returned home, I discovered that the count, before our interview, must have had in his possession a copy of Mr. Livingston’s Despatch No. 11, giving his own explanation of the whole transaction. During my absence, the post-office had sent me the duplicate of that despatch which, like all the communications I have ever received through the same channel, had been evidently opened. How it got there, I know not, because it had been forwarded to this city by the ship Birmingham from New York _via Charleston_.
