WHEN AND WHERE TO FIND FERNS 



stature dwindles with the increasing cold, and we 

 seldom encounter them on our winter walks. The 

 sterile fronds of a number of the Shield Ferns endure 

 till spring. The Purple Cliff Brake and the Walk- 

 ing Leaf are also proof against ice and snow. Even 

 in the middle of January the keen-eyed fern hunter 

 may hope to make some discovery of interest re- 

 garding the haunts and habits of his favorites.
