MY DEAR SIR:—What think you of forming a reserve cavalry corps of, say, 6000 for the Army of the Potomac? Might not such a corps be constituted from the cavalry of Sigel's and Slocum's corps, with scraps we could pick up here and there?

Yours truly,

A. LINCOLN. [ [!-- H2 anchor --] ]

TELEGRAM TO B. G. BROWN.

WASHINGTON, D. C., January 7, 1863. 5.30 P.M.

HON. B. GRATZ BROWN, Jefferson City, Mo.:

Yours of to-day just received. The administration takes no part between its friends in Missouri, of whom I, at least, consider you one; and I have never before had an intimation that appointees there were interfering, or were inclined to interfere.

A. LINCOLN. [ [!-- H2 anchor --] ]

CORRESPONDENCE WITH GENERAL A. E. BURNSIDE, JANUARY 8, 1863.
