entirely up to my control. Ask as many questions as you wish, provided
they are useful ones. Just say, without ceremony, 'Knops, why is this?
or, Knops, what is that?' and I, in return, if you will be so good as to
allow me, will say, frankly, 'Leo, this is this,' or 'that is that.' But
here is the entrance to our habitations. You will have to stoop a
little." Striking again with his tool, a panel slid open in the wall,
through which they crept.

It was still dark, but the air had changed greatly; instead of the musty
dampness of a vault, there was a soft warmth, which was fragrant and

On its floor was burning an immense bonfire, which flashed and flamed,
and around which was a bevy of dwarfs, shovelling on fuel from huge
heaps of sandal-wood. Every gallery swarmed with elves and dwarfs in all
sorts of odd costumes, but all bore little lanterns in their caps, and
