 form of propagating-frame is 

 a pot or box covered with a 

 pane of glass (Fig. 4) . To ad- 

 mit of ventilation, the glass is 

 tilted at intervals, or two 

 panes may be used and a space 

 allowed to remain between 



them. 



A common bell-glass or bell-jar makes one 



of the best and handiest propagating-frames, 



because it admits light on all sides and is 



convenient to handle (Fig. 5). It is partic- 



ularly serviceable in the 



propagation of tropical or 



"stove" plants; and it is

 answers the same purpose and accommo- 

 dates a larger number of plants. For certain 

 limited purposes, a fruit-jar may be used 

 as a bell-glass. Fig. 77 shows such use

 stretching thin muslin over a 

 wooden or wire frame, as in 

 Fig. 78. This device may be 

 used also for protecting plants 

 newly transplanted.
