sash. The 

 end abut- 

 ting against 

 the offices, 

 as already 

 noticed, is, 

 for unifor- 

 mity's sake, 

 constructed 

 the same in- 

 ternally as the other ends and sides of the 

 structure, but is filled in with ground glass, 

 so that nothing can be seen through it : 

 behind it is an open area 15 inches wide, to 

 admit air and light to the offices behind. 



We have avoided curved lines as much 

 as possible in the figures of the beds in 

 the flower garden connected with this 

 conservatory, as we propose them to be of 

 l^-inch slate set on edge, and the walks 

 gravelled. The circles being too small to 

 border with other than box edgings, we 

 propose to occupy them with vases, of 

 Grecian patterns, to be kept full of flower- 

 ing plants, and to give elevation, as it were, 

 to the monotony of the ground-plan. In 

 the centre is a fountain and basin of water. 



Fig. 511 is the front elevation : at a is 

 shown the end upright sash partially 

 opened, and run back behind the next to 

 it. The fan-lights b b, all round the house, 

 are filled in with violet-coloured glass in 

 single panes. The columns are tubular, 

 and convey the water from the gutter be- 

 hind the pediment to a cistern below the 

 house, from whence water is procured for 

 the plants. The whole roof is fixed, and 

 without rafters or framed sashes. The 

 top ventilation is placed in the lantern 

 at the top, every alternate glass panel of 

 which is moved by machinery, as seen 

 at fig. 31, art. Principles of Hothouse- 

 Building. The roof of the lantern is also 

 fixed, and of glass. 



Fig. 512 is the end elevation, while fig. 

 513 is the elevation of the corridor. 



Fig. 514 is a cross section, showing at 

 ddd the drainage below the bed for the 

 plants, as well as for admitting air to 

 their roots at the same time j the earthen- 

 ware pipes used for the purpose being 

 closely fitted to retain any water that may 

 find its way into them, until it is dis- 

 charged at their extreme ends, where they 

 terminate in sunk areas covered with 

 grating. From these, air enters them,
