October Looking Forward 



seem unlimited ; in addition to Daffodils, Hyacinths, 

 Squills, Crocuses, Grape Hyacinths (Muscari), Snowdrops, 

 one may grow even Lily of the Valley and Liliums, while 

 Alpine plants have been tried with some success. 



All greenhouse plants that have been out of doors 

 or in a frame for the summer, such as Zonal Geranium, 

 Cineraria, Cyclamen, Salvia, Primula, Chrysanthemum, 

 Indian Azalea, Hydrangea, Perpetual Carnation, etc., 

 ought now to be brought under glass. The latter should 

 be thoroughly cleansed for their reception, and I have 

 found nothing better for the purpose than a preparation 

 called Clubicide, which is to be had from seedsmen. If 

 the walls, floor and staging are first thoroughly hosed 

 and then syringed with Clubicide, there will be at least 

 a clean greenhouse to start with. Greenfly will probably 

 soon make its appearance and the simplest way to get 

 rid of it is by fumigating with one of the many 

 compounds sold for the purpose. It is much easier to 

 prevent the spread of greenfly than to destroy it when 

 leaves and shoots are badly attacked. 



Heating a Small Greenhouse. An unheated green- 

 house is apt to become rather depressing at this time of 

 year, chiefly owing to its chill and damp air and the 

 decaying leaves which this occasions. In spring it can 

 be made quite gay with spring bulbs in pots and several 

 early flowering plants and shrubs ; meanwhile these are 

 dormant, and the greenhouse is dull. The installation of 

 a simple heating apparatus enables one to grow a greater 

 variety of flowers and to keep the greenhouse bright 

 until the sunshine awakens spring blossom to life. In 

 the case of a large glasshouse, say 20 to 30 feet or more 

 long, the only really satisfactory plan is to install a boiler 

 outside the house and have it connected with a set of hot- 

 water pipes, work that is best left to a horticultural 

 builder. But for a smaller greenhouse, say from 9 to 15 

 feet long, a simpler method suffices. The most primitive 

 heating apparatus consists of a paraffin lamp and a series
