that could possibly be produced. 
The sights and illusions of the Star Chamber 
are so wonderful and so complete, that when we 
reluctantly take our leave of it, we feel as though 
we had passed a night in a new world, and that 
the morning had unexpectedly broken upon us 
before our astonished faculties had had time to 
comprehend the extraordinary transition of time 
and circumstances. 
With the exception of Echo River, says Dr. 
Wright, the Star Chamber is, perhaps, the most 
attractive object in the Cave. 
- The Floating Cloud Room connects the Star 
Chamber with Proctor’s Arcade. 
‘The clouds are produced by the scaling off of 
black gypsum from the ceiling, by an efflores- 
cence of the sulphate of soda beneath it, by which 
a white surface is exposed. They appear to be 
drifting from the Star Chamber over the Chief 
City. The Cloud Room is a quarter of a mile 
in length, and in height and width corresponds 
with the Star Chamber.
