We are told by the policeman who attends at one of the inner doorways to seat ourselves on a stone bench in an alcove, and wait our turn as is the custom here. The Stranger's Gallery will not hold more than a hundred persons when crowded; and when a heavy debate is in progress, on a great public measure, the gallery is sure to be full. Five persons are admitted to the gallery at a time as soon as a gap is made in the benches by the departure of an equal number of spectators. Should a man leave his seat in the alcove for an instant he is certain to lose his turn, and he will be compelled to go to the bottom place and begin over again. As soon as there is room, the policeman makes a sign to those in waiting, and he marshals the five persons who have tickets, and they follow him through several passages and halls to the Lobby of the Commons--a large, square hall, beautifully decorated, and, turning to the left, they all ascend a winding stair to the ante-room, where the tickets are examined by an old, white-haired gentleman who sits in a chair in evening dress, and, if correct, the batch are admitted to the Stranger's Gallery, which is on the same floor, at the end of another dark passage. [Sidenote: BILL OF FARE.] Before I leave the Lobby of the Commons, let me describe it briefly together with the Lunch Counter of the house, which even the greatest public men find it necessary to visit occasionally. It is a large square hall of lofty proportions, almost every inch of the walls and ceiling being ornamented in relief with the insignia of the Kingdom of Great Britain and Ireland.
