Cultivation of Ferns. 54 



blished. I therefore add a list of those only which are best 

 known, and easily procured, rather than of kinds almost 

 unknown, and which it would be difficult to obtain ; as it may 

 be useful to those who have inclination and means to begin a 

 collection. 



Connected with this subject, permit me to add a few observ- 

 ations. Every opportunity should be taken by those who 

 have distant or foreign correspondents, to engage them in col- 

 lecting the fronds of ferns. It is an easy task : they are light 

 of carriage, and may prove, when sent to a friend or cultivator, 

 an acceptable and useful present. They may be raised from 

 seed with the greatest ease. Their natural habitat may be 

 imitated either in hot-houses, or in the open garden ; whether 

 inhabitants of the dry or moist rock, the shady wood, or open 

 plain ; whether found growing on sound or decayed timber, 

 on clay, loam, or decomposed vegetable earth ; all these sub- 

 stances can be transferred with the plants, and placed in such 

 parts of the flower-garden as will correspond with their re- 

 spective habits and character. 



In a collection of ferns in a garden, they should always be 

 accompanied with the other plants of cryptogamous descrip- 

 tion usually found united with them in their native bed : of 

 such are various mosses, lichens, &c.
