He saw a number of people in the central space, and at the opposite end a large and imposing doorway at the top of a flight of steps, heavily curtained but giving a glimpse of some still larger hall beyond.

He perceived white men in red and other negroes in black and yellow standing stiffly about those portals.
As they crossed the gallery he heard a whisper from below, "The Sleeper," and was aware of a turning of heads, a hum of observation.

They entered another little passage in the wall of this ante-chamber, and then he found himself on an iron-railed gallery of metal that passed round the side of the great hall he had already seen through the curtains.

He entered the place at the corner, so that he received the fullest impression of its huge proportions.

The black in the wasp uniform stood aside like a well-trained servant, and closed the valve behind him.
Compared with any of the places Graham had seen thus far, this second hall appeared to be decorated with extreme richness.
