ulata) has never responded to my cultural 

 efforts beyond making a sickly growth which 

 disappeared before the end of the second 

 summer. 



The Hartford fern {Lygodium palmatum) 

 is said to take kindly to cultivation. It is not 

 so in my own experience on a town lot. 



The slender cliff brake (Cryptogramma 

 Stelleri) is an elusive little beauty. Sometimes 

 it is found growing in thick moss on rocky pro- 

 jections, and which can easily be taken off 

 intact. It would then seem to have no excuse 

 for not continuing the business of life on 

 some other rock in any shady corner. But 

 I do not believe that the species ever gains 

 a permanent foothold far from running 

 water or shaded ravines, as a damp atmos- 

 , phere is essential to ferns of such fragile 

 texture. 



Other species mentioned in the foregoing 

 list are marked as "unsuitable," merely upon 

 questions of taste, and should by all means 

 be included in collections where the greatest 

 possible range of species is desired.
