date from Nov. 10, 1864. On July 28, 1865, Secretary of the Treasury Hugh McCulloch wrote to Secretary of War Edwin M. Stanton recommending that Slack be appointed bvt. maj. gen. of vols., stating that Slack broke with the Democratic Party to support the war and that his appointment would "gratify a great many friends of the Administration, in Indiana."

"The political reasons for this Brevet are stronger, than the military—I cannot recommend the brevet." AES, ibid. On Jan. 11, 1866, USG disapproved Slack's appointment. ES, ibid. On June 23, however, USG wrote to Stanton. "I would respectfully recommend the Appointment, by Brevet, of Brig. Gen. Jas. R. Slack, U. S. Volunteers, to be Maj. General. General Slack served during the entire war and all, or nearly all the time in the field." ALS, ibid., ACP, 781S CB 1866. Slack was so appointed, as of March 13, 1865.

MAJ. GEN. H. W. HALLECK,
GEN. IN CHIEF, WASHINGTON D. C.
This will be handed to you by Mr. E. E. G. Barney, of Holly Springs Miss.
Mr. Barney is a Northern man but has resided in the south for a number of years, and having been largely connected with the rail‐ road interest of the South is extensively acquainted with that portion of our country. Mr. Barney took occation to show his devotion to the Union long before our forces reached his home and property. He has, I believe, never failed to get information to commanders at Memphis when he thought it important.
I have no hesitation in saying that I believe the most implicit confidence can be placed in Mr. B. and in all his statements.
I am Gen. very respectfully
your obt. svt.
