 atmosphere which so much prevails in this country. 

 Pineries should therefore be constructed so as to admit 

 and diffuse as much light and sunshine as can be had. 

 In the few months when at times the sun may be more 

 scorching than is desirable, a slight shading can easily 

 be appplied. "When the sash-and-rafter principle is 

 adopted, I would advise that the sashes should not be less

 light. Such houses are decidedly the best for summer
