 it should be covered, as is done in many stoves. As 

 climbhig and other plants, such as passiflora, bigno-

 ters, and which should be ])lanted inside the house; 

 the parapet should be placed on pillars, (as the 

 Grape-house, described in Section I. of the Forcing- 

 Garden), in order that their roots may have access 

 to a border made outside the house for their better 

 support.' A narrow border, however, of about 

 eighteen inches, should be made inside the parapet ; 

 in which these and other plants, such as double 

 flowering myrtles, tlie neater sorts of geraniums, the 

 Indian rose, fuchsia. Botany-bay plants, several 

 bulbs, and other dwarfy showy things, may be plant- 

 ed. 



This border takes place of the flues, as in the 

 Green.house described above : the walk or alley may 

 be of the same breadth, that is, thirty, or thirty- 

 six inches ; and. 



The space in the middle of the house, occupied 

 by the stage, becomes a pit for plants, such as oran- 

 ges, lemons, shaddocks, palms, myrtles, olives, and 

 many others ; which pit should be laid dry and 

 comfortable below, and should be about two feet 

 deep under the level of the walk, or ground-level of 

 the house. It should be separated from the flue by 

 a retaining wall raised to the same height, and a 

 three-inch cavity, in order that the heat may escape 

 by it from the flue, as observed above. A row of 

 small pillars should be built from the bottom of the 

 pit to its surface, on wliich the columns may bs
