October Looking Forward 



a set of small zinc pipes joined to an upright con- 

 struction that contains a small boiler at the top and a 

 space for a lamp at the base. At the side of the boiler 

 there is an opening in which a chimney is fixed, the upper 

 end passing through a lead pane purposely inserted in the 

 roof of the greenhouse. Thus all fumes from the lamp 

 pass outside. By means of rubber rings the pipes fit 

 closely into sockets near the boiler and the whole 

 apparatus can be fixed in an hour. A duplex burner 

 paraffin lamp is provided and if this is properly trimmed, 

 kept clean and carefully tended, the pipes get warm in 

 an hour and become hot soon af terwards; It is possible 

 to keep the greenhouse about 10 warmer than the tem- 

 perature out of doors. The use of a small iron pipe is 

 advised, one end being inserted in a hole at the base 

 of the greenhouse and the other end placed near the lamp 

 to create a draught and cause the lamp to burn brightly. 

 Water is poured into the pipes at the far end of the 

 apparatus, and must be replenished from time to time. 

 Possessing a heater of this kind one may grow such 

 flowers as Primula, Cineraria, Calceolaria, Perpetual Car- 

 nation, Roses in pots and many others. 



Lily of the Valley. In growing Lily of the Valley 

 in pots for the greenhouse it is necessary to purchase 

 flowering crowns, or, if they are lifted from the home 

 garden, to choose only those that are plump and thick. 

 Thin, pointed crowns will not bloom. A " crown," it may 

 be necessary to explain, is an individual root of Lily of 

 the Valley. For porting at this time of i;year ordinary 

 flowering crowns are suitable; they are potted firmly 

 about an inch apart, in pots of soil, placed in a frame for 

 four or five weeks and kept dark. At the end of that 

 time they may be brought into the greenhouse. Under 

 this method of treatment leaves will appear with the 

 flowers. If the roots are potted and placed directly in 

 the greenhouse the flowers will appear before the leaves. 

 The simplest way to force Lily of the Valley is to purchase
