The troops will be formed in line in the Avenue, north of the President's mansion, precisely at 11 o'clock a.m., Saturday, the 13th instant, with the right (Brevet Major Sedgwick's troop of light artillery) resting opposite the War Department.

The procession will move at 1 o'clock p.m., when minute guns will be fired by detachments of artillery stationed near St. John's church, the City Hall, and the Capitol, respectively.

On arriving on the north front of the Congressional Burial Ground the escort will be formed in two lines, the first consisting of the firing party, facing the cemetery and 30 paces from it; the second composed of the rest of the infantry, 20 paces in rear; the battery of artillery to take position on the rising ground 100 paces in rear of the second line.

At sunrise to-morrow (the 13th instant) a Federal salute will be fired from the military stations in the vicinity of Washington, minute guns between the hours of 1 and 3, and a national salute at the setting of the sun.

The usual badge of mourning will be worn on the left arm and on the hilt of the sword.

The Adjutant-General of the Army is charged with the details of the military arrangements of the day, aided by the Assistant Adjutants-General on duty at Washington, by Brevet Lieutenant-Colonel Swords, of the staff, and Lieutenant W.T. Sherman, Third Artillery.

The United States marshal of the District of Columbia having been charged with the direction of the civic procession, the military will cooperate in the general order of arrangements.
