CHAPTER VI. 



Mi FRAMES AND GLASS-HOUSES. 



"Th' uplifted frame, compact at every joint, 

 And overlaid with clear, translucent glass. 

 It settles next upon the sloping mount. 

 Whose sharp declivity shoots off secure 

 From the dash'd pane the deluge as it falls." — Cowper. 



THE amount of vegetation which can be obtained in any glass 

 structure is strictly limited by the extent of surface of glass 

 exposed to the light ; hence, when we desire, in this climate, many 

 plants out of their natural season, or which grow in a warmer climate, 

 we must have a proportionately extensive amount of glass. 



A great deal can be done with glass lights eight feet by four, 

 which may be conveniently arranged in groups of twos, threes, and 

 fours (fig. 86). The structure is very simply made. A strong stake 

 is driven into the ground at each of the four corners, and on the

outside slabs of timber about |-in. thick are nailed to these to form 

 the walls, and over the whole a wooden frame is placed to receive, 

 the lights.
