pas THE MAMMOTH CAVE. 
The awful sublimity of this dome, when 
strongly illuminated, exceeds anything ever pic- 
tured to a mind frenzied by opium or hashish. 
The Mammoth Dome is still enlarging. 
The brief time that we were unfortunately 
restricted to when we visited the Cave, did 
not permit us to make a personal inspection 
of either Pensacola Avenue or Sparks’ Avenue 
and Mammoth Dome, which we very much 
regret, and therefore are wholly indebted to 
Dr. Wright for the description which we have 
just given. 
There are several avenues not often fre- 
quented by visitors, of which we need make 
no mention whatever,—for the very good 
reason that we have no information to offer. 
Roaring River is another portion of the Cave 
which we did not visit, but Dr. Wright informs 
us that the avenue which communicates with 
Roaring River is entered at Cascade Hall, and 
is half a mile in length. He adds, that Roar- 
ing River resembles Echo River in size and ap- 
pearance, but has a louder echo. There is a 
cascade which falls into it, from which proceeds 
roaring sounds, and from which it has received 
its name. 
Kyeless fish and eyeless crawfish are found in
