 bed is to get the sash. 



Any old sash will do, whatever its shape or size. 

 Glazed for a window, it will doubtless leak when put 

 to this more trying use, but if it is reasonably tight

 differently, however, from the ordinary window-sash 

 and the way of doing it ought to be among the gardener's 

 accomplishments, for breakage is apt to occur. 



This shows the construction of Hotbed frame to receive

 you will see from the accompanying illustration, and 

 are "rabbeted" to receive the glass. Spread soft putty 

 along this rabbet, then, starting at the bottom of the
