APPENDIX. 423 



summer season ; square-rigged vessels at fixed anchorage, and the fore- 

 and-aft-rigged ones, whose sails traverse, such as schooners, cutters, 

 and coasting vessels, with cables of lengths to allow of their sailino- 

 without touching the edge of the pond ; and these continue constantly 

 traversing the pond when there is any wind. This room also contains a 

 variety of the warlike instruments of the savages of different countries, 

 a bust of Lord Nelson, one of the Duke of Wellington, some pictures in 

 mosaic, and a number of East Indian curiosities. It serves, also, as a 

 lobby to the orangery. 



3, The orangery. The paths are of slate, and the centre bed, or pit, for 

 the orange trees is covered with an open wooden grating, on which are 

 placed the smaller pots ; while the larger ones, and the boxes and tubs, 

 are let down through openings made in the grating, as deep as it may be 

 necessary for the proper effect of the heads of the trees. This house, 

 and that for Orchidacese, are heated from the boiler indicated at 61. 



4, Orchidaceous and fern house, in which a is the stage for Orchidacese, 

 and b a cone of rockwork, chiefly of vitrified bricks, for ferns. These 

 ferns, amountipg to above two dozen species, all sprang up accidentally 

 from the soil attached to some plants which were sent to Mr. Harrison 

 from Rio Janeiro and other parts of South America. The shelves round 

 the house are also occupied with Orchidaceae, ail 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 practised by the Duke of Devon- 

 shire 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 6?, 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 jig. 8, in p. 428. 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
