work is rather tedious, requiring care and labor, and manv 

 disappointments may be experienced. The collection of the 

 spores at the proper time is the first and all-important matter. 

 This can only be done by close and frequent e.xamination of 

 thefronds— the dark color of the sori, and, if closely examined, 

 the bursting of the sporangia or cases containing the spores, 

 will indicate when they are ripe and fit to remove. The fronds 



sliould then be cut and carefully wrapped in smooth wrapping 

 paper, placing the packages in some warm, perfectly dry 

 place. After a week or so the spores will have shed, when 

 they should be sifted clean, and either sown immediately or 

 stored away in tightly corked vials until ready for use. The 

 sooner they are sown the better, however, as those of many 

 varieties soon lose their vitality.
