The Culture of Greenhouse Orchids

 conditions of this system, it works admirably. 

 And it spreads fast. But several amateurs of my 

 acquaintance have abandoned it in haste after trial.

 the bracken roots and that is deadly. On this

 innovation skilfully applied, I do not recommend

It will be found convenient to fix a stake of
