The Fern House . 
41 
P. phegopteris, Platycerium alcicorne (suitable to sus¬ 
pend on a block of wood ; it is almost hardy). Todea 
pellucida (this grows finely in a cool house, if in a damp, 
shady, and still place; wind it cannot endure). 
For Elevated Positions in the Fronts of Rock¬ 
eries —that is to say, to grow as wall ferns, and all 
requiring plenty of air : Asplenium trichomanes , A . 
adiantum nigrum , A. marinum , Ceterach officinarum ) 
Allosorus crispus (a sunny position near the door will 
suit this and Asplenium trichomanes), Polypodium 
vulgare and its varieties, especially Cambricum and 
Hibernica . 
The most hardy of the tree ferns is Dicksonw 
antarctica , which is as easy to grow as a common 
lastrea, provided it has enough water. 
For Baskets, take Pteris scaberula , Adiantum setu~ 
losum , Asplenium flabellifolium , Camptosorus rhizophyl- 
lus , Davallia pyxidata , Niphobolus lingua , and any of 
the free-growing hardy ferns that run about freely, such 
as Lastrea thelypteris and Onoclea sensibilis . 
If you should wish to create in your house or out of 
doors a constant trickling of water for the benefit of 
some fountain-loving ferns or mosses, take any large 
vessel, in the bottom of which you can break or bore a 
small hole. Cover the hole with a fiat tile, and over 
that put two inches of the finest sand. Fill the vessel 
with water daily, and it will run gently as long as there 
is a drop left at the fountain head. If an ornamental 
vase should be used for the purpose, it might be utilized 
by placing in it a pot containing some semi-aquatic 
plant.
