at their posts during the time of greatest danger. Since a sufficient force has been each night stationed in the public buildings, it is believed the officers generally hold themselves ready, in case of an alarm, to repair at once to their posts to give such advice and aid as they can. Since the assignment was made other officers have arrived, and some have left the city, which should perhaps cause a new arrangement to be made:
The staff of the General-in-Chief, General Totten and Captain Fry, to repair to headquarters on an alarm. General L. Thomas to command in Georgetown. Major McDowell, assisted by Captain J. N. Macomb and Lieutenant Woodruff, Topographical Engineers, assigned to Capitol Hill. Captain Meigs is now here, and should be the engineer of the Capitol building. Captain Garesche to repair to the General Post-Office. Captain W. F. Raynolds, Topographical Engineers, to the Patent Office. Captain Shiras to Corcoran's building, corner of Fifteenth and F streets, where there are public officers. Colonel Larned to repair to Winder's building. Major Hunter, paymaster, to the President's mansion. Colonel Stone to command of Executive square, assisted by Captain Wright, as engineer. Captain W. R. Palmer, Topographical Engineers, to the Coast Survey. Captain A. A. Humphreys to the Smithsonian Institution. Major H. Bache, Department of State. [Great seal.] Captain Franklin, Topographical Engineers, Treasury building, and in charge of a deport of ammunition placed there for use in case of attack.
