It swung open, and we followed him through into a pitch-dark chamber of some kind.

But the door we came in by had hardly slammed behind us when a bright light broke through a square hole in the ceiling and displayed a flight of rock-hewn steps.

Some one overhead had removed a stone plug from the hole.
The Mahatma motioned to King to go first, but as King refused he led the way again, going through the square hole overhead as handily as any seaman swinging himself into the cross-trees.

King followed him and I stood on the top step with head and shoulders through the opening surveying the prospect before scrambling up after him.
I was looking between King's legs.

The light came from three large wood-fires placed over at the left end of a rectangular chamber hewn out of solid rock.
