GREENHOUSES. 



Before entering into any details respecting the cultivation of green- 

 house flowering plants, it may be necessary to offer some preHminary 

 remarks on the arrangement and erection of such structm-es as are neces- 

 sary for their successful cultivation, founding our observations on the 

 principle of economy of fuel, elegance of design, and fitness for the 

 end in viev^^ We cannot, perhaps, do better than precede these remarks 

 by the accompanying view of the Duke of Northumberland's splendid 

 conservatory at Sion House. 



In taking a retrospective view of what has been already written on this 

 subject, it vrould appear, that authors for the most part have confined 

 themselves to providing for the wants of the great and the opident, whdle 

 the more humble, and by far the most numerous class of plant cultivators 

 have been left as it were, without the benefit of instruction. To supply 

 this deficiency will be one of the objects kept in ^iew in the following 

 remarks ; Yve shall also endeavour to treat this subject so as to embrace 

 the greatest possible variety of circumstances, and as a rule from which 

 there should be few deviations, we recommend the adaptation of the 

 structm-e — first, to the circumstances of the proprietor ; next, to the 

 capabilities of the situation ; and lastly, to the description of plants 

 intended to be cultivated in them.
