The troops will then return, the music playing the President's march, the drums previously unmuffled. The uniform companies of militia are invited to join in arms the volunteer corps. The commanders at particular stations, conforming generally to this plan, will make such exceptions as will accommodate it to situation. At places where processions of unarmed citizens shall take place it is the wish of the Major-General that the military ceremonial should be united, and the particular commanders at those places are authorized to vary the plan so as to adapt it to the circumstances. Brigadier-General MacPherson is charged to superintend the ceremonial in the city of Philadelphia; Major Tousard will attend to Fort Mifflin and will cooperate with him. The day of performing the ceremonial at each station is left to the particular commander. Major-General Pinckney will make such further arrangements within his district as he shall deem expedient. PHILIP CHURCH, _Aid-de-Camp._ In conformity to the above the volunteers of the city and county of Philadelphia in the service of the United States will parade, completely equipped, at the manege, in Chesnut street, on Thursday next, the 26th instant, at 10 o'clock a.m. The officers, together with the uniform companies of militia who may think proper to join on this mournful occasion, will please to signify their intention to Brigadier-General MacPherson at his quarters on or before Tuesday next at 1 o'clock p.m., in order that the necessary arrangement may be made to pay the last sad tribute of veneration to the manes of the late Commander in Chief of the Armies of the United States. By order of Brigadier-General MacPherson: JONATHAN WILLIAMS, _Aid-de-Camp._ [The following interesting paper is extracted from a speech of Senator W.C. Rives, of Virginia, delivered in the United States Senate February 12, 1839, on a bill to prevent the interference of certain Federal officers in elections. (See Congressional Globe, Twenty-fifth Congress, third session, Vol. VII, Appendix, p. 409.) This order President Jefferson caused to be issued by the heads of the several Departments shortly after his inauguration, March 4, 1801. References are made to it in several publications, but the originals could not be found.]
