116 THE MAMMOTH CAVE. 
Upon leaving Washington Hall, and before 
reaching Cleveland’s Cabinet, we pass through 
the Snowball Room. The ceiling is studded 
with white nodules of gypsum, which vary in 
diameter from two to four inches. The atmos- 
phere of the room is too damp for the gypsum 
to assume the forms of flowers and filaments, 
as it does in Cleveland’s Cabinet. The re- 
semblance of these nodules to snowballs is 
complete.
