DEAR SIR,--I wrote you last on the 8th. We have still not a word from our Envoys. This long silence (if they have been silent) proves things are not going on very roughly. If they have not been silent, it proves their information, if made public, would check the disposition to arm. I had flattered myself, from the progress of the public sentiment against arming, that the same progress had taken place in the Legislature. But I am assured by those who have better opportunities of forming a good judgment, that if the question against arming is carried at all, it will not be by more than a majority of two; and particularly, that there will not be more than four votes against it from the five eastern States, or five votes at the utmost. You will have perceived that Dayton has gone over completely. He expects to be appointed Secretary of War, in the room of M'Henry, who, it is said, will retire. He has been told, as report goes, that they would not have confidence enough in him to appoint him. The desire of inspiring them with more, seems the only way to account for the eclat which he chooses to give to his conversion. You will have seen the disgusting proceedings in the case of Lyon: if they would have accepted even of a commitment to the serjeant, it might have been had. But to get rid of his vote was the most material object. These proceedings must degrade the General Government, and lead the people to lean more on their State governments, which have been sunk under the early popularity of the former. This day, the question of the jury in cases of impeachment comes on. There is no doubt how it will go. The general division of the Senate is twenty-two and ten; and under the probable prospect of what it will forever be, I see nothing in the mode of proceeding by impeachment but the most formidable weapon for the purposes of dominant faction that ever was contrived. It would be the most effectual one of getting rid of any man whom they consider as dangerous to their views, and I do not know that we could count on one-third in an emergency. All depends then on the House of Representatives, who are the impeachers; and there the majorities are of one, two, or three only; and these sometimes one way and sometimes another: in a question of pure party they have the majority, and we do not know what circumstances may turn up to increase that majority temporarily, if not permanently. I know of no solid purpose of punishment which the courts of law are not equal to, and history shows, that in England, impeachment has been an engine more of passion than justice. A great ball is to be given here on the 22d, and in other great towns of the Union. This is, at least, very indelicate, and probably excites uneasy sensations in some. I see in it, however, this useful deduction, that the birth days which have been kept, have been, not those of the President, but of the General. I enclose with the newspapers, the two acts of parliament passed
