Phelps, Esq, for Prossecuting Atty–[Attorney] is received– I have previously had similar letters on behalf of two others for the same place–2 As I do not personally know Mr Phelps, the best I can do for him, is to lay your letter before the Governor, with an indorsement of you, as a good and true man, which I shall most cheerfully do.3
Yours as everA. Lincoln

3Lincoln endorsed Jonathan K. Cooper’s May 7 letter as described above. Cooper had sought Lincoln’s aid in recommending George Phelps to Governor William A. Bissell for appointment as state's attorney of the Fifth Judicial Circuit—a position recently vacated by John S. Bailey, who resigned. Ultimately, Governor Bissell appointed Louis H. Waters to serve out the remainder of Bailey’s term as state’s attorney. Waters held the position until 1860.
