In a division of political parties nearly equal, the main aisle from the southern entrance would be the separating line. As it was, the Republican Senators occupied not only the eastern half of the chamber, but many of them were seated on the other side, the comparatively few Democratic Senators sitting still further to the west. Seated in the gallery, the spectator has a favorable position to survey the grand historic scene which passes below. His eye is naturally first attracted to the chair which is constitutionally the seat of the second dignitary in the land--the Vice-President of the United States. That office, however, has no incumbent, since he who took oath a few months before to perform its duties was called to occupy a higher place, made vacant by a most atrocious crime. The event, however, cost the Senate little loss of dignity, since the chair is filled by a President _pro tempore_ of great ability and excellence--Lafayette S. Foster, Senator from Connecticut. The eye of the spectator naturally seeks out Charles Sumner, who sits away on the outer tier of seats, toward the south-east corner of the chamber; and near him, on the left, are seen the late Governors, now Senators, Morgan and Yates, of New York and Illinois. Immediately in front of them, on the middle tier of seats, is an assemblage of old and distinguished Senators--Trumbull, Wilson, Wade, and Fessenden. To the right of the Vice-President's chair, and in the row of seats neares this desk, sits the venerable and learned lawyer, Reverdy Johnson, of Maryland. Just in his rear sits the youthful Sprague, of Rhode Island, to whose right is seen Sherman, of Ohio. To the rear of these Senators, in the outer segment of seats, sits, or perhaps stands, Garrett Davis, of Kentucky, the most garrulous of old men, continually out of temper with the majority, yet all the time marked by what he calls his "usual courtesy." To the left of Davis, beyond Nesmith, of Oregon, and the other and more silent Senator from Kentucky, sits Saulsbury, of Delaware, unless he should be traversing the carpeted space in the rear of his seat, like a sentinel of the Senate. Far different is the sight presented to the spectator who looks down from the galleries of the House of Representatives. The immense area below is supplied with two hundred and fifty-three seats, with desks arranged in semi-circular rows, having a point in front of the Speaker's desk as a focus. On the right of the spectator, as he looks from the gallery in front of the Speaker, is the Republican side of the House. But this prosperous organization has grown so rapidly since its birth, ten years ago, that it has overstepped all old and traditional party limitations. One-half of the House is not sufficient to afford its representatives adequate accommodations. Republican members have passed over the main aisle, and occupy half of the Democratic side, having pressed the thin ranks of their opponents to the extreme left.
