Thomas: "I shall require the mails of the War Department to be delivered to me and shall transact the business of the office." Stanton: "You shall not have them, and I order you to your room." No. 3. On Tuesday, April 2nd, the prosecution put in evidence a letter from the President to Gen. Grant, dated Feb. 10, 1868, in answer to a prior letter front the General. The President's letter, as introduced in evidence, purported to contain certain enclosures relating to the subject matter of the President's letter. The following is that portion of the President's letter which speaks of the enclosures accompanying and included therein: GENERAL: The extraordinary character of your letter of the 3rd instant would seem to preclude any reply on my part; but the manner in which publicity has been given to the correspondence of which that letter forms a part, and the grave questions which are involved, induce me to take this mode of giving, as a proper sequel to the communications which have passed between us, the statements of the five members of the cabinet who were present on the occasion of our conversation on the 14th ultimo. Copies of the letters which they have addressed to me upon the subject are accordingly herewith enclosed. Counsel for the President objected that the letter introduced by the prosecution was not evidence in the case unless the managers should also produce the enclosures therein referred to and made a part of the same. The following was the vote on sustaining the objection: Yeas--Bayard, Conkling, Davis, Dixon, Doolittle, Fowler, Grimes, Henderson, Hendricks, Johnson, McCreery, Morrill of Vermont Norton, Patterson of Tennessee, Ross, Sprague, Trumbull, Van Winkle, Vickers and Willey--20--10 Republicans and 10 Democrats. Nays--Anthony, Buckalew, Cameron, Cattell, Chandler, Cole, Conness, Corbett, Cragin, Drake, Edmunds, Ferry, Fessenden, Frelinghuysen, Howard, Howe, Morgan, Morrill of Maine, Nye, Patterson of New Hampshire, Pomeroy, Ramsay, Sherman, Stewart, Sumner, Thayer, Tipton, Williams, and Wilson--29--28 Republicans and 1 Democrat. So the evidence offered by the prosecution was admitted as offered, without the enclosures referred to, the objection by the defense not being sustained. (For these rejected enclosures see appendix.) No. 4. The prosecution offered to prove (Mr. Geo. A. Wallace, of the Treasury Department, on the stand): That after the President had determined on the removal of Mr. Stanton, Secretary of War, in spite of the action of the Senate, there being no vacancy in the office of Assistant Secretary of the Treasury, the President unlawfully appointed his friend and theretofore private secretary, Edmund Cooper, to that position, as one of the means by which he intended to defeat the tenure of civil office act and other laws of Congress.
