116 THE xMAMMOTH 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.
