THE PRACTICAL GARDENER. 



VENTILATION. 



As the cold weather approaches, ventilation should be les- 

 sened, both as the admission of air would tend to lower the 

 temperature of the house, and also as the plants do not require 

 so much of it at this season as hitherto. When from the heat 

 of any warm days that occur, that opening the sashes may be- 

 come necessary, it should only be for a short time, as the warmer 

 the house is shut up at night, the less fire-heat it will require 

 to maintain a proper degree of heat throughout the night. 



INSECTS. 



Insects, the almost constant attendants on tropical plants, 

 will still require looking after. The means already proposed 

 may be adopted, or others that may be more eHectual may be 

 devised by the cultivator ; at all events, vigilance and repeated 

 application are necessary to keep them under.
