THE FERN PARADISE. 
The same conditions of soil, moisture, and situa- 
tion required by Cystopteris regia will avail for 
the successful culture of the Mountain Bladder 
Fern. Beautiful and delicate in the extreme, it 
will well repay all the care and attention which 
may be lavished upon it. If it could be planted 
near a fountain, where by some arrangement water 
could be made to trickle over its roots, or the foun- 
tain spray could envelop the whole plant, then 
the natural conditions under which it grows most 
luxuriantly would be very nearly supplied, and 
the growth of this exquisite fern would be all 
that the fern cultivator could wish.
