480 Movable Glass Case for Orange Trees, Sfc. 



Art. X. Plan and Description of a jnovahle Glass Case 

 for the Winter Protection of Orange Trees, Camellias, Sj-c, 

 planted in the open Air. By Mr. J. Haythorn. 



Sir, 



It would be a most desirable object to accomplish, could 

 we but have the more beautiful exotics so treated, as that in 

 the summer months they might have all the advantages of the 

 open air, and the proprietors all the pleasure of seeing them 

 growing as if they were natives. I have long thought this 

 practicable, and therefore throw out a few hints for yourself 

 or some of your readers to improve. 



Supposing that any part of a principal walk in the flower- 

 garden, or pleasure-ground, were so situated as to be deemed 

 worthy of such an embellishment ; all that is necessary would 

 be to consider how far such fine objects would fall in and asso- 

 ciate with the other trees and shrubs around ; and also how 

 far the protecting frames would or would not appear displaced. 

 Should no objection arise on this score, we have only to de- 

 vise the means of defending the trees in winter by an eco- 

 nomical covering which would not be unsightly ; and, also, a 

 convenient mode of giving the necessary heat. 



The most simple covering would be square or circular 

 wooden frames, with glazed pyramidal roofs ; constructed in 

 separate panels for the greater convenience of putting up and 

 taking down. The dimensions, height of sides, and pitch of 

 roofs, would depend on the size of the tree to be covered, al- 

 ways allowing for increasing growth. Heat might be supplied 

 by any of the. common methods, in flues (from a concealed 

 fire-place), either of brick or metal, so conducted as to sur- 

 round each tree in going and returning. These flues, of 

 course, must be sunk beneath the surface, and contained in 

 cavities of brickwork, covered above by turf or gravel, as cir- 

 cumstances direct. 



I send you herewith a sketch of the frame {fg. 122.), as the 

 first idea which occurred to me, but 

 which I submit to your emendation. 



I know not whether my advising 

 such expensive erections for handsome 

 exotics, however economically executed, 

 would be justifiable, were it not that 

 such frames would be as useful in the 

 fruit-garden in summer, as they might be in the flower-garden m 

 winter. Standard trees of the best fruit might be planted and 

 trained to be so covered; vines in a circular trelHs, might 

 have their fruit brought to perfection ; in short, they might be
