. DESCRIPTION OF THE PLANT STOVE AT CHATSWORTH. 
The whole length of the building is one hundred and ten feet, the breadth six- 
teen feet six inches, inside the walls. The pit on which the large plants are placed 
is seven feet wide, elevated one foot above the walk. 
The front walk is paved with stones, and is five feet six inches wide ; betwixt 
each of the front windows is a kind of semi-circular stone basin, extending two 
feet six inches from the front wall ; these basins are filled with rich soil, and are 
planted with trailing plants, as Thunbergia alata, &c. &c, which are trained up 
trellis to the front wall ; they are also occupied by a collection of stove ferns. 
The central division of the house is 
occupied with rockwork, in the front of 
which is formed a basin for aquatic 
plants, which basin extends beneath the 
rockwork to the back wall, where it is 
supplied by a tap. 
There are four furnaces, two of Witly's for the front flues, and two common 
ones for the flues under the back elevated walk ; all the flues pass into the back 
wall in the centre of the house. 
The heat from the front flues is admitted through iron grates laid in the front 
walk, two feet six inches long, and eight inches broad : a hot air cavity also passes 
round each of the front basins, and sends heat into the house, by means of a grate 
opposite each of the front windows. 
The back walk f, is elevated seven feet from the ground, and is ascended by 
a flight of eight steps. This walk is two feet six inches wide, and on the side next 
the wall is an elevated border, one foot wide, chiefly appropriated to succulent 
plants ; the hot air from the flues is admitted betwixt the bars of wood, of which 
the walk is composed, and has on the side next the plants a neat wooden balustrade. 
Behind the house are the back sheds.
