THE MAMMOTH CAVE. 169 
The Main Cave is terminated abruptly by 
rocks that lave 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 we 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 rigut of 
the Gothic Galleries, and enter the Gothic 
Arcade.
