98 INTERIOR ARRANGEMENTS. 



An end view of this structure is shown in the frontispiece. As 

 the ground, in this case, descends gradually from the base of the 

 mansion, a considerable depth of parapet wall is necessary to 

 bring the floor of the conservatory to the desired level, and the 

 requisite distance from the roof. Curved roofs can only be 

 adopted where the building admits them without jarring dis- 

 cordantly with the general architecture, and, in some instances, 

 straight-lined roofs will be preferable ; but in all cases where 

 curvilinear roofs can be made to harmonize with the building, 

 they are decidedly to be preferred, on account of the superior 

 beauty of curved lines viewed in contrast with the surrounding 

 scenery, and also on account of the superior beauty of the struc- 

 ture from within, in harmony with curved figures of the walks 

 and borders of a house, such as that we have here described.
