 also. keep the plants as^near the light as possible, and give them plenty 

 of ventilation during fine weather, but avoid cold draughts., 



A season of rest is very advantageous to the plants, causing them to 

 flower more freely and to grow more vigorously afterwards. Those 

 plants which are growing on blocks will require a good supply of water 

 at their roots ■ every day during summer, and twice or three timfes a 

 week in winter. 



Gattleyas requii'e to be kept perfectly clean and free from insects. 

 They are subject to the white scale, which should never be allowed to 

 establish itself, as it is then difficult to remove, and the plants are in 

 great danger of being injured. In order to keep the plants free, they 

 should be carefully looked over every three or four weeks, and sponged 

 with clean water of the same temperature as that of the house.; They 

 are also subject to the 

 attacks of thrips ; this 

 pest should be kept 

 down by steaming or 

 fumigating with to- 

 bacco paper. The}' 

 are propagated by 

 dividing the plants. 



The following list 

 comprises the most 

 beautiful and valuable
