THE MAMMOTH CAVE. 105 



nue leading off from Silliman's Avenue and re- 

 turning into it a short distance farther on. It 

 presents several beautiful points, and is worth 

 exploring. 



6. The Hill of Fatigue is appropriately 

 named, being hard to climb, but is not otherwise 

 worthy of note. 



7. The Great Western, so called from the 

 supposition that in appearance it represents the 

 immense ship known as the Great Eastern, is 

 an enormous rock, many times larger than any 

 vessel, the end of which closely resembles the 

 stern of a ship. To make use of nautical lan- 

 guage, the rudder is turned to the starboard side. 



8. The Rabbit is a large stone, which is sup- 

 posed to resemble the animal whose name it 

 bears. 



9. Ole Bull's Concert-Room is situated to the 

 left of the avenue. It is thirty feet wide, forty 

 long, and twenty high. When the great vio- 

 linist made his first tour through the United 

 States, he visited the Cave and performed in the 

 room which has received his name. 



At the end of Silliman's Avenue begins 

 Rhoda's Arcade, which arises half a mile from 

 the Pass of El Ghor ; it is five hundred yards 

 in length, and from five to ten feet in height.
