[ Autographs ] Orlando M. Poe 1832-1895 Union brigadier general who commanded a brigade at Fredericksburg, fought Longstreet at Knox ville, and later served as Sherman's Chief Engineer at Atlanta and inthe March to the Sea. A.L.S. on Headquarters Army of the United States letterhead, 2pp. 8vo., Washington, Jan. 22, 1879 to Major General Montgomery Meigs. In part: ''..I return to you, duly signed, your application in the American Society of Civil Engineers ...see that all is in proper shape and then transmit it to the Society at New York..." Interestingly, on the verso someone (Meigs?) has added aschematic drawing of a piston. Fine.
