glass and width of the stage, forms these spaces at each end into two very neat 
lobbies. These are appropriated to the growth of the fine sorts of climbing plants ; 
and the stage is capable of containing from 800 to 1000 plants in pots. 
A Stage for plants. 
B Arched wall for support of stage. 
C Arched wall and back flue. 
D Raised walk or gangway in front of stage. 
E Arched wall for support of walk. 
F Arched wall and front flue. 
G Peach trellis. 
H Stone for support of peach trellis. 
I Made border for vines. 
K Peach border. 
L Front Shelf, for Cape bulbs, &c. 
M Lobbies at each end of the house.
