THE MAMMOTH CAVE 127 



named in honor of Professor Cleveland, the 

 disthiguished mineralogist. 



At the terniination of Cleveland's Cabinet we 

 arrive at the base of the Rocky Mountain. This 

 mountain is one hundred feet high, and is en- 

 tirely formed of rocks that have fallen from 

 above. On the top of the Rocky Mountain there 

 is a stalagmite two feet high and six inches in 

 diameter, termed Cleopatra's Needle. 



On the farther side of the Rocky Mountain is 

 a gorge seventy feet deep and one hundred feet 

 wide, termed Dismal Hollow. The Cave at the 

 Mountain divides into three branches. That to 

 the right leads to Sandstone Dome, which is in- 

 teresting from the fact that the stone of which it 

 is composed indicates that the top of the Dome 

 is near the surface of the earth. The branch to 

 the left communicates with Crogan's Hall.* The 

 central one is termed Franklin Avenue, and ex- 

 tends from Dismal Hollow to Serena's Arbor. 



Franklin Avenue, as before stated, extends 

 from Dismal Hollow to Serena's Arbor, a dis- 

 tance of a quarter of a mile. It varies in width 

 from thirty to sixty feet; it has a wild and 

 gloomy appearance. 



* Named for Dr. Crogan, a former proprietor of tlie Cave, — 

 improperly spelled Grogan by Dr. Wright.
