to duty as Chief of Cavalry at the camp. Brevet Brig.-Gen. Harvey Brown as Chief of Artillery, according to his brevet. A Chief of the Infantry arm will hereafter be designated. The Chief of Ordnance, the Quartermaster-General, Commissary-General, Surgeon-General, and Paymaster-General, will each designate an experienced regular officer as the chief of their respective departments at the camp. These officers will be subject to the orders of Gen. Wool, and under his supervision will, without delay, establish a hospital, and depots of all the supplies necessary for the health and efficiency of the troops at points where issues may be conveniently made. The long experience of the veteran officer assigned to command the camp will dictate the most efficient details for brigading, equipping, drilling and disciplining the Reserve Corps d'armee to be thus formed under him. Chiefs of the different Staff Bureaux are hereby directed to aid him by promptly meeting his reasonable requisitions for the material of war. By order of the Secretary of War.
L. Thomas, Adjutant-General.
