We have for some time expected, that the Chevalier de la Luzerne would obtain a promotion in the diplomatic line, by being appointed to some of the courts where this country keeps an ambassador. But none of the vacancies taking place, which had been counted on, I think the present disposition is to require his return to his station in America. He told me himself, lately, that he should return in the spring. I have never pressed this matter on the court, though I knew it to be desirable and desired on our part; because if the compulsion on him to return had been the work of Congress, he would have returned in such ill temper with them, as to disappoint them in the good they expected from it. He would for ever have laid at their door his failure of promotion. I did not press it for another reason, which is, that I have great reason to believe, that the character of the Count de Moutier, who would go, were the Chevalier to be otherwise provided for, would give the most perfect satisfaction in America. As you have now returned into Congress, it will become of importance, that you should form a just estimate of certain public characters; on which, therefore, I will give you such notes as my knowledge of them has furnished me with. You will compare them with the materials you are otherwise possessed of, and decide on a view of the whole. You know the opinion I formerly entertained of my friend, Mr. Adams. * * * and the Governor were the first who shook that opinion. I afterwards saw proofs, which convicted him of a degree of vanity, and of a blindness to it, of which no germ appeared in Congress. A seven months’ intimacy with him here and as many weeks in London, have given me opportunities of studying him closely. He is vain, irritable, and a bad calculator of the force and probable effect of the motives which govern men. This is all the ill which can possibly be said of him. He is as disinterested as the Being who made him: he is profound in his views; and accurate in his judgment, except where knowledge of the world is necessary to form a judgment. He is so amiable, that I pronounce you will love him, if ever you become acquainted with him. He would be, as he was, a great man in Congress.
