APPENDIX. 
shelves round the house are also occupied with Orchidacese, all of 
which are in pots, in order that, when they come into flower, they 
may be removed to the green-house ; as, when thus treated, as prac- 
tised by the Duke of Devonshire at Chatsworth, they continue much 
longer in bloom, than when kept in the degree of heat necessary for 
their growth. 
4 c, Lobby between the orangery (3) and the conservatory (5.) 
4 d , An aviary for canaries, separated from the conservatory and the 
lobby by a wire grating, and from, the orchidaceous house by a wall. 
Both the aviary and the lobby have a glass roof in the same plane as 
that of the conservatory, as may be seen in Fig. 8, in p. 466. In the 
winter season the temperature of the aviary being the same as that of 
the conservatory, the birds require little or no care, except giving them 
food ; while they sing freely at that season, and greatly enliven this 
part of the garden scenery. 
5, Conservatory, with vines under the rafters. The walks are slate, the 
shrubs are planted in a bed of free soil edged with slate, and the back 
wall is covered with different species of Passiflora, and with the Tacso- 
nia pinnatistipula. 
6, Camellia-house. The camellias kept in pots ; the rafters covered with 
vines, and the back wall with passiflbras and other climbers. This 
house, and also 5, are heated from one boiler, as indicated at 64. 
7, Geranium-house. The roof is in the ridge and furrow manner of Mr. 
Paxton. This house, and also 8, 9, and 10, are heated from the boiler 
indicated at 89. 
8, Botanic stove. The roof is in the ridge and furrow manner of Paxton. 
The sides of the pit are formed of slabs of slate ; and' there is a slate 
box at e, containing a plant of Musa Cavendislm with a spike of fruit, 
two or three of which ripen off weekly. F. is a cistern for stove aqua- 
tics. There is a plant of Brugmansia suavolens {Datura arborea L .) 
15 ft. high, with a head 13 ft. in diameter. When we saw it, Aug. 
10th, 277 blossoms were expanded at once, producing an effect upon 
the spectator under the tree, when looking up, which no language can 
describe. Last year it produced successions of blossoms, in one of 
which 600 were fully expanded at one time. This year it has had 
five successions of blossoms, and another is now coming out as the 
plant expands in growth. There is a large Brugmansia coccinea in 
this house. Both these plants are in the free soil.
