Ferns), many persons fail to cultivate this Fern with 
success ; probably from the use of fine soil in too 
large masses. Naturally this is a rupestral (rock- 
growing) plant, and this condition should be imitated 
by its being planted among masses of porous sand- 
stone in the interstices of which, and only in the 
interstices, a little sandy soil should be placed. It 
would no doubt also be an advantage to plant some- 
what horizontally instead of too vertically and to have 
the upper stones large enough to shade the crowns of 
the plants from the sun. Many Ferns do not need 
so much shade as is given in a collection to the 
tenderer sorts ; and this partial shadowing would be 
more congenial to some of the wall or rock species 
than a more general exclusion of the sun.
