;>to. The Wall in the Back part 

 of the Stove fhould be at leait thir- 

 teenlnches thick; but eighteen Inch- 

 es is ftill better ; becaufe the thicker 

 the out fide Wall is built, the more 

 the Heat of the Flues will be kept 

 in the Houfe ; and carried up, about 

 nine Ftet above the Surface of the 

 Bark-bed ; and from the Top of this 

 Wall, there mould be a floping Roof 

 to the Crown-piece where the Clari- 

 es Hide in. This Crown - piece 

 fhould be about fixteen Feet high 

 from the Surface of the Bark -bed or 

 Floor, which will give a fufficient 

 Declivity to the floping Glafles to 

 carry oft* the Wet, and be of a reason- 

 able Height for containing Plants 

 of a moderate Size. The Back- 

 roof may be flated, covered with 

 Lead, or tiled, according to the Fan- 

 cy of the Owner : but the Manner 

 of this outfide Building is better ex- 

 prefs'd by the annex'd Plan, than is 

 poffible to be defer i bed in Words. 



In the Front of the Houfe there 

 fhould be a Walk, about eighteen or 

 twenty Inches wide, for the Conve- 

 niency of walking; next to which 

 the Bark-pit muft be placed, which 

 mould be in Width proportionable 

 to the Breadth of the Houfe : if the 

 Houfe is twelve Feet wide, which 

 is a due Proportion, the Pit may be 

 feven Feet wide ; and behind the 

 Pit fhould be aWalk eighteen Inch- 

 es wide, to pafs in order to water 

 the Plants, &c. then there will be 

 twenty - two Inches left next the 

 Back-wall, . to ere<5t the Flues, which 

 muft be all railed above the Top of 

 the Bark bed : thefe Flues ought to 

 be one Foot wide in the Clear, that 

 they may not be too foon flopped 

 with the Soot ; and the lower Flue, 

 into which the Smoke firft enters 

 from the Fire, mould be two Feet 

 deep in the Clear; and this may be 

 covered with broad Tiles ; over this 



S T 



the fecond Flue muft be returned 

 back again ; which may be eighteen 

 Inches deep, and covered on theTop 

 as before ; and fo in like manner the 

 Flues may be returned over each 

 other three or four times, that the 

 Heat maybe fpent before the Smoke 

 pafles off. The Thicknefs of the 

 Wall in Front of thefe Flues need 

 not be more than four Inches ; but 

 it muft be well jointed with Morter, 

 and plafter'd withinfide to prevent 

 the Smoke from getting into the 

 Houfe ; and the Outfide fhould be 

 plaftered with Morter, and covered 

 with a coarfe Cloth to keep the 

 Morter from cracking, as it is 

 praclis'd in fetting up Coppers: if 

 this be carefully done, there will be 

 no Danger of the Smoke entering 

 theHoufe,which can'tbe too careful- 

 ly guarded againft;forthereis nothing 

 more injurious to Plants than Smoke, 

 which will caufe them to drop their 

 Leaves ; *and if it continue long in 

 the Houfe, will intirely deftroy them. 



The Fire-place may be made either 

 at one End, or in the Middle, ac- 

 cording as there is moft Convenien- 

 cy ; for where-ever it is plac'd, it 

 mould have a Shed over it, and not 

 be expofed to the open Air ; for it 

 will be impofliblq to make the Fire 

 burn equally, where the Wind has 

 full Ingrefs to it ; and it will be trou- 

 blefome to attend the Firein wet Wea- 

 ther, where it is expos'd to the Rain. 



The Contrivance of the Furnace 

 muft be according to the Fuel which 

 is defign'd to barn : but as Turf is 

 the beft Firing for Stoves, where it 

 can be had, becaufe it burns more 

 moderately , and lafts longer, than 

 any other Sort of Fuel, and fo re- 

 quires lefs Attendance, I fhall de- 

 fcribe a proper Sort of Furnace for 

 that PurpoCe. 



The Who'e of this Furnace 

 fhould be erected within the Houfe, 



which
