model. The flat had generally more than 

 one half the panes of glass broken, while 

 the Vandyke remained uninjured." He 

 also invites the inspection of the curious 

 to his domicile, and gives reference to 

 several roofs of this description which he 

 constructed for various individuals ; but 

 none of them are dated earlier than 

 thirteen years ago, at which time the 

 large conservatory at Chatsworth was in 

 existence. 



" This style (the ridge-and-furrow) forms 

 the basis of the plan which promises to 

 subvert the monotonous interior arrange- 

 ments" hitherto followed, " inasmuch as, 

 when applied on a grand scale, it facili- 

 tates the covering of larger areas of 

 ground, in which the absolute necessity 

 of departing from long-cherished arrange- 

 ments must eventually lead to great 

 improvements in this respect. But now, 

 as even generally applied, this style of 

 building leaves the interior unchanged — 

 for the same mode of disposing of the 

 plants is in most cases followed. This 

 ought not to be. Gardens would lose 

 half their charms were we to see the 

 same thing imagined everywhere. It is, 

 in fact, in the endless variety, in connec- 

 tion with intrinsic beauty, of which they 

 admit, that their fascinations rest. And 

 why should it not be so with horticul- 

 tural erections for the growth of exotic 

 vegetation ? Why should these, which 

 are to a certain extent invested with the 

 additional charm of variety, be deprived of 

 the charm of that variety 1 Why should 

 we not have groves, and lakes, and 

 flower gardens, and rocks, and caverns, 

 with their appropriate vegetation within 

 as well as without 1 In the former case, 

 their beauties would be available either 

 for admiration or study at all seasons; 

 in the latter, the fickleness of our climate 

 often acts as a preventative to both these 

 exercises." — Annals of Horticulture. 



The greatest advantage of a ridge-and- 

 furrow roof is, that any extent of area 

 may be covered without internal walls. 

 Indeed, no walls whatever are required, 

 as the sides and ends may be glass close 

 to the ground — the whole being supported 

 on cast-iron tubular columns, with cast- 

 iron valleys or gutters. A good idea of 

 the effect and practicability of roofing over 

 a whole garden may be obtained by a 

 careful examination of some of our most 



extensive railway stations — that at Derby, 

 for example, which we believe could be 

 extended over a hundred acres if required. 



Plate XII. and the description are 

 of a garden covered with glass, upon the 

 ridge-and-furrow principle, and heated 

 by hot-water pipes and vases, upon a 

 principle we believe to be efficient, and 

 at the same time ornamental. The work- 

 ing drawings were prepared by us in 1 840, 

 with a view to its being erected at Dal- 

 keith. The temperature intended to be 

 maintained was that sufficient for repelling 

 frost, in order to the formation of a gar- 

 den in which a supply of flowers, and the 

 more delicate kinds of fruit and vegetables, 

 might be procured throughout the year. 



Plate XI L, fig. 1, is an exterior eleva- 

 tion in projection, supposed to stand clear 

 of all other buildings, and upon an eleva- 

 tion of 3 feet above the surrounding 

 ground, enclosed within a parapet, and 

 surrounded by a broad gravel or pave- 

 ment walk. 



The building in question was intended 

 to be simple and plain in all its details ; 

 but there is no reason why an expression 

 of architectural character should not be 

 given to it, by employing architectural 

 columns for the support of the valleys 

 instead of plain ones, and carrying a 

 cornice or frieze along above them, with 

 appropriate ornaments planted on the 

 pediments. These things, with an archi- 

 tectural parapet surrounding it — with the 

 necessary flights of steps leading to the 

 terrace, and appropriate balustrading and 

 vases — would give effect, which, whatever 

 be the style of architecture, cannot fail to 

 please. The Doric, Ionic, or Corinthian 

 orders may be adopted, as may best har- 

 monise with the style of the mansion : 

 nay, even the Gothic or old English may, 

 with certain modifications, be substituted. 



Fig. 2 is the elevation of the whole of 

 the upright sashes and pediments, from 

 the plinth to the plate under the gutters, 

 all of which are movable, being made to 

 run on two lines of iron rails attached to 

 the top of the plinth, and in two checks 

 or square grooves in the wall-plate under 

 the ends of the gutters. Or if a deep 

 cornice or frieze is indulged in, these 

 movable sashes may be hung upon the 

 suspension principle, by which their move- 

 ment will be greatly facilitated. 



The bottom rails of the sashes being
