A figure in a simpler garb than that of my guide, but of similar
fashion, was standing motionless near the threshold. My guide touched
it twice with his staff, and it put itself into a rapid and gliding
movement, skimming noiselessly over the floor. Gazing on it, I then saw
that it was no living form, but a mechanical automaton. It might be two
minutes after it vanished through a doorless opening, half screened by
curtains at the other end of the hall, when through the same opening
advanced a boy of about twelve years old, with features closely
resembling those of my guide, so that they seemed to me evidently son
and father. On seeing me the child uttered a cry, and lifted a staff
like that borne by my guide, as if in menace. At a word from the elder
he dropped it. The two then conversed for some moments, examining me
while they spoke. The child touched my garments, and stroked my face
with evident curiosity, uttering a sound like a laugh, but with an
hilarity more subdued that the mirth of our laughter. Presently the roof
of the hall opened, and a platform descended, seemingly constructed
on the same principle as the 'lifts' used in hotels and warehouses for
mounting from one story to another.

The stranger placed himself and the child on the platform, and motioned
to me to do the same, which I did. We ascended quickly and safely, and
alighted in the midst of a corridor with doorways on either side.

Through one of these doorways I was conducted into a chamber fitted up
with an oriental splendour; the walls were tesselated with spars, and
metals, and uncut jewels; cushions and divans abounded; apertures as for
windows but unglazed, were made in the chamber opening to the floor;
and as I passed along I observed that these openings led into spacious
balconies, and commanded views of the illumined landscape without. In
