 and the many hazards to which the ufe of thcle fires 

 is liable, havejuftly brought them into difufe with all 

 fkilful perfons; and as the contrivances of flues, and 

 of the fires, are but fmall charges in their firft ereding, 

 they are much to be preferred to any other method 

 for warming the air of the houfe. 

 The wall on the back part of the houfe fliould be 

 either laid over with ftucco, or plaftered with mortar, 

 and white-wafhed, for otherwife the air in fevere froft 

 will penetrate through the walls, efpecially when the

 the moifture imbibed from the air, which, beintr' re- 

 plete with the rancid vapours perfpired from the other 

 plants, occafioned the leaves to grow pale, and in a 

 Ihort time they decayed and dropped off; which I 

 have often obferved has been the cafe with many other 

 fucculent plants, when placed in thofe houfcs which 

 were filled with many forts of Evergreen trees that 

 required to be frequently watered. 

 Therefore, to avoid the inconvenience which attends 

 the placing of plants of very different natures in the 

 fame houfe, it will be very proper to have two winery 



the cafe in moft fevere winters. There are fomeper- I added to the main Green-houfe, which, if placed ?n

 Green-houfes, but when this is done, it is proper to 



the manner expreffcd in the annexed plan, will greatlv 

 add to the beauty of the building, and alfo colied a 



plafter the walls with lime and hair behind the wainf- j greater Ihare of heat. In this plan the Green-houfe is 



cot, to keep oqt the cold ; and when they arc lined 

 with wainfcot, they ftiould be painted white, as fhoiild 

 the cieling, and every part withinfide of the houle ; 

 for this reflefts the rays of light in a much greater 

 quantity than any other colour, and is of fignal fer- 

 vice to plants, efpecially in the winter, when the houle 

 is pretty much clofcd, and but a fmall Ihare of light 

 as admitted through the windows ; for at fuch times 

 I have obferved, that in fome Green-houfes which 

 have been painted black, or of a dark colour, the 

 plants have caft moft of their leaves. . - '

 that from the time of the fun's firft appearance upon 

 any part of the building, until it goes off at night, it 

 is conftantly rcficfted from one part to the other, and 

 the cold winds are alfo kept off from the front of the 

 main Green-houfe hereby ; and in the area of this place 

 you may contrive to place many of the moft tender 

 exotic plants, which will bear to be 'expofed in the
