During the afternoon and night of the 23d, the Fifteenth, Seventeenth, and Twentieth Corps, crossed Long Bridge, bivouacked in the streets about the Capitol, and the Fourteenth Corps closed up to the bridge.  The morning of the 24th was extremely beautiful, and the ground was in splendid order for our review.  The streets were filled with people to see the pageant, armed with bouquets of flowers for their favorite regiments or heroes, and every thing was propitious.  Punctually at 9 A.M. the signal-gun was fired, when in person, attended by General Howard and all my staff, I rode slowly down Pennsylvania Avenue, the crowds of men, women, and children, densely lining the sidewalks, and almost obstructing the way.  We were followed close by General Logan and the head of the Fifteenth Corps.  When I reached the Treasury-building, and looked back, the sight was simply magnificent.  The column was compact, and the glittering muskets looked like a solid mass of steel, moving with the regularity of a pendulum.  We passed the Treasury building, in front of which and of the White House was an immense throng of people, for whom extensive stands had been prepared on both sides of the avenue.  As I neared the brick-house opposite the lower corner of Lafayette Square, some one asked me to notice Mr. Seward, who, still feeble and bandaged for his wounds, had been removed there that he might behold the troops.  I moved in that direction and took off my hat to Mr. Seward, who sat at an upper window.  He recognized the salute, returned it, and then we rode on steadily past the President, saluting with our swords.  All on his stand arose and acknowledged the salute.  Then, turning into the gate of the presidential grounds, we left our horses with orderlies, and went upon the stand, where I found Mrs. Sherman, with her father and son.  Passing them, I shook hands with the President, General Grant, and each member of the cabinet.  As I approached Mr. Stanton, he offered me his hand, but I declined it publicly, and the fact was universally noticed.  I then took my post on the left of the President, and for six hours and a half stood, while the army passed in the order of the Fifteenth, Seventeenth, Twentieth, and Fourteenth Corps.  It was, in my judgment, the most magnificent army in existence—­sixty-five thousand men, in splendid physique, who had just completed a march of nearly two thousand miles in a hostile country, in good drill, and who realized that they were being closely scrutinized by thousands of their fellow-countrymen and by foreigners.  Division after division passed, each commander of an army corps or division coming on the stand during the passage of his command, to be presented to the President, cabinet, and spectators.  The steadiness and firmness of the tread, the careful dress on the guides, the uniform intervals between the companies, all eyes directly to the front, and the tattered and bullet-ridden flags, festooned with flowers, all attracted universal
