STRUCTURES ADAPTED TO PARTICULAR PURPOSES.

and dwelling-houses, without reference to the position of the 

 structure, or the purpose for which it was built. 



Fig. 25 shows the appearance of the house, on the proportions 

 which are given in the above plan, (Fig. 24,) which, in our 

 opinion, admits of more room for plants than any other form 

 that can be built at the same cost ; for, although we might adopt 

 a semi-circular form for the end toward the most prominent 

 point of view, it must be remembered that this would add con- 

 siderably to its cost. Our object here is to give the sketch of 

 the best and cheapest kind of house that can be erected for plant- 

 growing, and such is the one here given. 



This house may be placed in any situation, as regards aspect. 

 It may be attached at one end to any other building, without 

 much injury to its efficiency as a plant-house ; and where it is 

 found absolutely necessary to attach green-houses to the walls 

 of other buildings, they should, by all means, be constructed 

 after the plan here given, or under some architectural modifica- 

 tion of it, avoiding, if possible, that old, and now almost obsolete,

system, of laying the roof up to the wall, as in a common 

 grapery, or of making the front of heavy pilasters and massive 

 wood-work, like the orange-houses of the middle ages. The 

 method of construction here described is that in which the 

 plants enjoy the largest share of light ; and this house is the 

 easiest managed with respect to air and heat in winter, and 

 moisture and shade in summer of all other methods which 

 have come under our experience.
