be the most favourable aspect for a ridge- 

 and -furrow roof, whether it were supported 

 against a back wall or had a rectangular 

 yoof with vertical lights on each side. 



Conservatories, however, which are ap- 

 pendages to the house, must depend for 

 I'.ieir aspect on the position it occupies, 

 txcept where the principal rooms lie to the 

 l.orlh. No plant-house can possibly pros- 

 per in this aspect, since the house shades it 

 from the south sun ; nevertheless, with 

 these rooms it must be connected, or it 

 fails in its object ; and a passage or corridor 

 connecting it, covered with glass, must 

 lead to some locality, either to east, or 

 west, or south, where a more genial aspect 

 can be obtained for the conservatory. 



MG. 2. RIDGE AND FURROW CONSERVATORY. 



Where a glass corridor becomes necessary, 

 it should be made subservient to the 

 objects of the conservatory by the intro- 

 duction of baskets, trailing plants, vases 

 occupying niches, and other attractions. 



As regards its architectural style, the 

 conservatory should, at least, be in har- 

 mony with that of the house : if ornaments 

 are permitted, they should be Gothic, 

 Tudor, or Grecian, according as the 

 house is of one character or the other : 

 in this, as in all other matters, congruity 

 is to be studied. A pretty design for a 

 ridge-and-furrow roof conservatory, suitable 

 for a handsome villa residence, is given in 

 Fig. 2. 



The conservatory, properly speaking, is 

 a house in which the plants occupy beds 

 and borders as in the garden, but on a 



smaller scale : sometimes the plants are 

 permanent ones, more frequently they 

 stand in pots, plunged into the soil, or 

 in tubs standing on its surface, or in vases 

 occupying pedestals. Much has been 

 written on the arrangements of con- 

 servatories, but the shape and size of 

 these glazed buildings must, of course, 

 always be determined upon by the situ- 

 ation. It must suffice here to observe that 

 the panes of glass should be large, with as 

 little sash-work as possible, and that the 

 best mode of heating is with hot -water 

 pipes. The heating apparatus of the con- 

 servatory may generally be so managed 

 as to warm the hall and staircase,

 ordinary soil is suitable for the annuals 

 and many of the perennials, but some of 

 the less hardy kinds require a compost of
