 be considered as very small indeed : — add, that in 

 many cases, and especially where there was a ten-

 plants in pots, or bulbs in water-glasses, are kept in 

 a room, the same objection may be raised ; for though 

 the surface of the pots and glasses may be completely 

 covered with moss to lessen evaporation, yet that co- 

 vering is far from being able to prevent it. How- 

 ever, those whose scruples as to health will not allow 

 them to open into their green-houses from a sitting- 

 room, may still look into them from thence, and, 

 fixing the glazed casements that separate their at- 

 mospheres, may enter by some exterior communica-

 garden. 



Sect. IL Position of the Green-house. 



The position of the green-house is the next point 

 of consideration. The south south-east is unques- 

 tionably the best, and corresponds also with the best 

 position for a breakfasting-room, which ought to 

 embrace the morning sun, and invite to go abroad. 

 But this, though preferable both for the plants, from
