Position of Green-house Furnaces. 247 



shrubs in the beds as standing separately, or isolated from one 

 another; the object being to admit of each particular shrub 

 being covered with flowers from the ground upwards, as in the 

 case of those in the garden of the Rev. Thomas Garnier. (X. 129.) 

 We have shown no outline to the boundary plantation {m, in 



Jig. 31.); because we consider the trees and shrubs composing 

 it to be planted on turf; and we have shown but few detached 

 trees on the inner lawn among the beds, supposing what are 

 necessary, to be included in the beds of shrubs. We do not say 

 that this is the plan that we should prefer for improving^. 29., 

 but merely that it is a very good plan. Much will depend on 

 the height of the floor of the principal living-rooms above that 

 of the external surface : if this is not considerable, and if the 

 eye is not raised several yards above the symmetrical figure (/, in 



Jig. 31.), there will be an apparent want of extent, which always 

 gives a disagreeable impression. We shall not, however, enter 

 into this subject farther at present, than to observe that the 

 treatment of the foreground, or, in other words, of the lawn 

 immediately in front of a house, must always be governed by 

 the character of the more distant scenery, whether within the 

 grounds or beyond them, as stated in p. 125. 



Art. VII. On the Advantages of building the Furnaces of Green- 

 houses, and other Descriptions of Houses for Plants, 'within the 

 House. By Mr. W. Anderson, F.L.S. H.S. &c., Curator of the 

 Botanic Garden, Chelsea. 



These last thirty years we have been looking for some re- 

 forms in many of our old practices ; and certainly much has been 

 done by individuals in the way of heating by water ; but it is 

 strange that the practice of having the furnaces of conservatories 

 and forcing-houses always in the back shed should still prevail, 

 though no other objection can be made to having them in the 

 house but the inconvenience arising from dust and sulphureous 

 smells, which are also applicable to the parlour fire. 



Our attention was directed to this absurdity many years back, 

 by the effects arising from the fires being placed inside the large 

 green-house here, which is 95 ft. long, 20 ft. broad, and 21 ft. 

 high. This green-house has a furnace at each end, but so low 

 as to have the flues under the floor, with a flap to go down to the 

 fireplaces. With a fire in the end next the wind, we keep out 

 the frost until the thermometer falls to 20° ; below 20°, we apply 

 both fires. The back, roof, and ends of this house are dark ; 

 the nine windows in front are 5 ft. high by 4 ft. broad, and are 

 very open. This house, which was built in 1731, is the only 

 one now remaining which those great men, Sir Hans Sloane
