^er them both Ufeful and Ornamcn- 

 -tal, hath been acquired : And fmce 

 there are many Particulars to be 

 obferv'd in the Conflrufiion of 

 thefe Houfes, whereby they will 

 be greatly improved, lo I thought 

 it neceflary, not only to give the 

 beft Inftrudlions for this I was ca- 

 pable of i but alfo to give a Deiign 

 of one in the Manner I would 

 chufe to ercd: it, upon the anncx'd 

 Copper-PJate. 



As to the Length of thefe Houfes, 

 that muft be proportion^! to the 

 Number of Plants they are to con- 

 tain, or the Fancy ot the Owner; 

 but their Depth fhould never be 

 greater than eighteen or twcnry 

 Feet in the Clear, and the Length 

 ot the Windows fnould be at ieafl 

 equal to the Depth of the Houfe, 

 and if they are fomewhat longer, 

 it will be ftill the better: Thefe 

 Windows fliould be carried up quite 

 to the Ceiling, that there may be 

 no Room for dead Air in the upper 

 Part of the Houfe; and they fhould 

 come down within about ten Inches 

 or a Foot of the Floor ; their Breadth 

 iliould be proportioned to the 

 Length ot the Houfe ; which in a 

 fmall Green- Houle, may be four 

 Feet broad ; but in a large one, they 

 fl^ould be fix Feet : The Piers be- 

 tween thefe Windows fhould be as 

 narrow as polTiblc to fupport the 

 Building ; for which Reafon, I 

 ihouki chufe to have them either 

 of Stone, or of folid hard Bricks j 

 for if they are built with fine rubb'd 

 Bricks, thole are generally fb fbtt, 

 that the Piers will require to be 

 made thicker, otherwife the Build- 

 ing will be in Danger of falling in 

 a Ihort Time, efpecially if you have 

 any Rooms over the Green- houfe : 

 which is what I would always ad- 

 vife, as being of great Ufe, to keep 

 this Froft out in very hard Winters.

If thefe Piers are made v/irh Stone, 

 I would have them about two Feet 

 broad m Front, and llop'd ott back- 

 wards to about eighteen Inches 

 broad, whereby the Rays of the 

 Sun will not be taken off or ob- 

 Ibudted by the Corners of the Piers; 

 which it v/ould be, if they were 

 fquarc. And if they were made 

 ot Iblid Bricks, two Feet fqu;ire 

 wouid be ftrong enough to fup-- 

 port the Building. 



At the Back of the Grcen-houf* 

 there may be erect-jd a Houk for 

 Tools, and many other Purpofes, 

 which will be extreme ufeful, and 

 alfo prevent the Froft from enrring 

 the Houie that Way ; fo that the 

 Wall bctv/cen thefe need not be 

 more than two Bricks and a half in 

 Thickncfs; whereas if it were quite 

 expos'd behind, it iliould be three 

 Bricks, or three Bricks and a half 

 in Thicknefs ; and by this Contri- 

 vance, it you are wiiling to make 

 a handfome Building, and to have a 

 noble Room over the Grecn-houfe, 

 you may make the Room to come 

 over the Tool-houfe, and carry up 

 the Stair-cafe in the Back, fo as not 

 to be lecn in the Green- houfe ; and 

 hereby you may liave a Room 

 twenty-five or thirty Feet in Width, 

 and of a proportionable Length : 

 and under this Srair-cafe there flioald 

 be a private Door into the Grecn- 

 houfe, at which the Gardener may 

 enter in hard frofty Weather, when 

 it will not be fate to open any of 

 the Glalfes in the Front. The Floor 

 of the Green-houfe, which ihould 

 be laid either with Marble, Stone, 

 or Broad Tiles, according to the 

 Fancy of the Owner, muft be rais'd 

 two Feet above the Level of the 

 Ground whereon the Houfe is plac'd, 

 which, if in dry Ground, will be 

 fufficient i but if the Situation be 

 moiH and fpringy, and thereby
