 suitable for other ferns, and must, during their 

 season of active growth, receive plenty of water

 diately cease to be gold and silver ferns, and only 

 look like poor examples of other species which have 

 caught the drippings of the white or yellow wash 

 of some fresco-painter. Ferns of this class re-

 even thrive under a little direct sunshine, provided 

 it be not at noon nor in hot weather. When well 

 grown they are very elegant, and are particularly 

 adapted to exhibition-purposes. They are not, as 

 a rule, good for the fern-case.
