Act 1, Scene 2 Mr. Frank. Now. About the noise. While the men are in the building below, we must have complete quiet. Everr sound can be heard down there, not only in the worksrooms, but in the offices too. The men come at about eight-thirty, and leave at about five-thirty. So, to be perfectly safe, from eight in the morning until six in the evening we must move only when it is necessary, and then in stockinged feet. We must not speak above a whisper. We must not run any water. We cannot use the sink, or even, forgive me, the w. c. The pipes go down through the workrooms. It would be heard. No trash...

What type of speech is this?
