The little sandy-haired woman had flung herself forward over the back of the chair in front of her. With a tremulous murmur that sounded like ‘My Saviour!’ she extended her arms towards the screen. Then she buried her face in her hands. It was apparent that she was uttering a prayer. At this moment the entire group of people broke into a deep, slow, rhythmical chant of ‘B-B! . . . B-B! . . . B-B!’ over and over again, very slowly, with a long pause between the first ‘B’ and the second - a heavy, murmurous sound, somehow curiously savage, in the background of which one seemed to hear the stamp of naked feet and the throbbing of tom-toms. For perhaps as much as thirty seconds they kept it up. It was a refrain that was often heard in moments of overwhelming emotion. Partly it was a sort of hymn to the wisdom and majesty of Big Brother, but still more it was an act of self-hypnosis, a deliberate drowning of consciousness by means of rhythmic noise.
