Dear Stuart: McRoberts  was elected senator yesterday. The vote stood: McRoberts, seventy-seven; Cyrus Edwards, fifty; E. D. Baker, one; absent, three. This affair of appointment to office is very annoying---more so to you than to me, doubtless. I am, as you know, opposed to removals to make places for our friends. Bearing this in mind, I express my preference in a few cases, as follows: For marshal, first, John Dawson; second, Dr. B. F. Edwards. For postmaster here, Dr. Henry;  Carlinville, Joseph C. Howell. There is no question of the propriety of removing the postmaster at Carlinville. I have been told by so many different persons as to preclude all doubt of its truth, that he boldly refused to deliver from his office during the canvass all documents franked by Whig members of Congress. Yours, LINCOLN.
