THE MAMMOTH CAVE. 153 



Roaring River, as well as sunfish and black 

 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. Tt 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.
