Cult, This plant grows best in 

 turfy peat soil, either in a box or 



it should be kept rather 

 for this purpose the pots 

 may be kept in pans of water. If 

 moss is allow^ed to grow on the 

 surface of the mould it will tend 

 greatly to the health of the plants, 

 or moss may be planted on the sur- 

 face of the soil around the plants. .^„„.^^ ^*w«^ ^^.
