sand, and finely-powdered sandstone in equal parts. 
This is to be pressed firmly together, and then the 
cauder or main root very carefully arranged upon the 
surface, fixing it by means of a few very small hooked 
pegs the smaller in size and quantity the better. Then 
strew a little sand and powdered stone over the surface, 
just enough to cover and settle the roots. This being 
done, the whole is to receive a liberal watering from a 
very fine-rosed watering-pot, and left for a short time to 
settle. Place the pot in a saucer, the top of which is to 
be below the level of the top of the first layer of stone 
in the pot. This saucer is to be kept full of water, 
with a bell-glass turned over the pot, and to rest in the 
saucer of water. Place the whole in a warm green- 
house or stove, and by keeping the saucer filled with 
water success may be relied upon. Similar directions 
may be followed for cultivating this Fern upon a larger 
scale. Be careful always to keep the atmosphere moist 
and warm, which moisture will be secured by keeping 
the pan full of water. This Fern may be increased by 
division, although very shy of this process, and also by 
its seed, or fructification, which is, perhaps, the best 
mode, although this Fern is very delicate and tender 
in a young state.
