state. Thougli they will not flourish Avithout an abundant supply 

 of moisture, yet it should never be allowed to stagnate about tlie 

 crown or the roots. 



6. Insects. 



With ordinary care, Ferns are not liable to suffer material 

 injury from the attacks of insects. The young fronds, however, 

 when but partially developed and in a very succulent state, are 

 sometimes attacked by aphides, which, if not removed, do them 

 considerable injury. The remedy, however, is simple. The 

 damp atmosphere, and the frequent washings and syringings 

 which the plants ought to have, are greatly conducive to rid 

 them of insects as well as filth of every description.
