THE MAMMOTH CAVE. 109 



10. Wellington's Gallery is not attractive. 



11. Hebe's Spring is about four feet in diam- 

 eter, and one foot and a half in depth. Its 

 water .is charged witli sulphuretted hydrogen. 

 Twenty years ago, as we are informed by 

 Dr. Wright, there was no sulphur in this 

 Spring, and at the present time, when it has 

 been undisturbed for several hours, pure water 

 is found upon the surface, and sulphur water 

 at the bottom, indicating the fact that it is 

 supplied with sulphur water at the bottom and 

 pure water near the surface which come from 

 entirely different sources. 



Eyeless crawfish have been found in Hebe's 

 Spring. 



At the distance of half a mile beyond Hebe's 

 Spring, the Pass of El Ghor communicates 

 with a body of water, the extent of which is 

 unknown, called the Mystic River.
