crawfish, both of which are provided with 
eyes. 
Marion’s Avenue, Dr. Wright informs us, is 
about a mile and a half long, and arises in 
Washington Hall. It varies from twenty to 
sixty feet in width, and from eight to forty in 
height. The floor is covered with sand, and 
the walls are composed of white limestone, 
which resembles cumulus clouds. The far end 
of the avenue divides into two branches,—that 
to the right leading to Paradise and Portia’s 
Parterre, and that to the left to Zoe’s Grotto. 
The walls and ceiling of the avenue termed 
Paradise are covered with gypsum flowers. 
There is a dome in Paradise Avenue which 
is composed of sandstone. It is called Digby’s 
Dome. 
Portia’s Parterre is entered from the left 
wall of Paradise Avenue. It is half a mile in 
length, and contains the same kind of flowers 
that are found in Cleveland’s Cabinet. It was 
discovered about twelve years ago, and is com- 
monly known as the New Discovery. 
Upon leaving Gorin’s Dome we returned to 
the Giant’s Coffin, on our way to the Star 
Chamber.
