AND CONSERVATORY. 



nerally thrive, there are certain rales to be observed, 

 and errors to be guarded against, which I shall brief- 

 ly point out. 



Green-houses with upright fronts, and with per- 

 pendicular lights only, whether the columns that se- 

 parate them be of wood, or of masonry, are the most; 

 objectionable ; as the plants in such are always 

 drawn up weak, and are distorted by continually 

 stretching towards the light. Neither do they en- 

 joy the genial effects of the sun, except in the win- 

 ter months, when his rays, though feeble., strike ho- 

 rizontally on the windows, and for a few hours in 

 the middle of the day perhaps, shine on the low 

 plants, and those placed most forward. If such 

 houses be very wide, they are the most objectionable 

 on that account ; as, in that case, the plants placed 

 near to the back of the stage are never visited by the 

 rays of the sun, and enjoy but little light to what 

 they may require *. 



But such green-houses may be, and indeed have 

 been much improved, by taking off their leaden or 



* Such, generally, were the primitive green-houses in this 

 country, and such may still be found in almost every county ; 

 many of which look more like tombs, or places of worship, than 

 .compartments for the reception and cultivation of plants, which 

 ought always to be light, airy, and cheerful. We sometimes 

 h'nd them so situated too, as that the rays of the sun can hardly 

 ever beam upon the house, much less on the plants contained in. 

 It ; being often set to improper aspects, and frequently shaded, 

 or almost covered up by trees, or by tall shrubbry.
