THE MAMMOTH CAVE. 169 



The Main Cave is terminated abruptly by 

 rocks that have fallen from above. It must 

 not, however, be supposed that this is the end 

 of it, for there can be no doubt that it was 

 closed at this point in the same manner as 

 Dickson's Cave was terminated, and that the 

 removal of the obstructing rock would open a 

 communication with a cave of the same size as 

 the one v^e have been attempting to describe. 



Retracing our steps by the route just passed 

 over, we now return to the Second Hoppers, 

 used by the saltpetre miners, mount a flight of 

 wooden steps, fifteen feet high, to the right of 

 the Gothic Galleries, and enter the Gothic 

 Arcade.
