T 



^.ould be two Feet (5eep m tlie 

 Clear, and this may be cover 'd 

 either with Caft Iron Plates or 

 broad Tiles i over this the fecond 

 Flue muft be return'd back again, 

 which may be eighteen Inches deep, 

 and cover'd on the Top as before j 

 and fo in like iiianner the Flues 

 may be return'd over each other 

 five' or lix times, that the Heat 

 may be fpent before the Smoak 

 pafTcs off. The Thicknefs of the 

 Wall in Front of thefe Flues need 

 not be more than four Inches, but 

 mull be well jointed with Mortar, 

 and plaifter'd withiniide to prevent 

 the Smoak from getting into the 

 Houfe, and the Outlide fliould be 

 faced with Mortar, and cover'd 

 w^ith a coarfe Gloth, to keep the 

 Mortar from cracking, as is pra- 

 d:is'd in fetting up Coppers j if this 

 be carefully done, there will be no 

 Danger of the Smoak entering the 

 Houfe, which can't be too care- 

 fully avoided , for there is nothing 

 more injurious to Plants than Smoak, 

 w^hich will caufe them to drop their 

 Leaves, and if it continue long in 

 the Houf3: will intirely deftroy 'em. 

 The Fire-place may be made ci- 

 ther at one End, or in the Middle, 

 according as there is mod Conve- 

 niency, tor v/herc-ever it is plac'd, 

 it fliould have a Shed over it, and 

 not be expos'd to the open Air^ 

 for it will be impoiTible to make 

 the Fire burn equally, where the 

 Wind has full Egrefs to it, and it 

 will be troublefome to attend the 

 Fire in wet Weather, where it is 

 expos'd to the Rain. 



The Contrivance of the Furnace 

 muft be according to the Fuel 

 which is dciiiTn'd to burn; 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, 



St 



atid fo requires lefTer Attendance, t 

 fhall defcribe a proper SOrt of Fut* 

 nace for that Purpofe. 



The whole of this Furnace fliouH 

 be erefted within the Houfe, which 

 will be a great Addition to the 

 Heat, and the Front-Wall on the 

 Outfide of the Fire-place, next the 

 Shed, fliduld be two Bricks thick, 

 the better to prevent the Heat from 

 coming out that Way. The Door 

 of the Furnace, at which the Fuel 

 is put in, muft be as fmali as con- 

 veniently may bd to admit of the 

 Fuel J and this Door fliould be plac'd 

 near the upper Part of the Furnace, 

 and made to fhut as clofe as pofFible, 

 fo that there may but little of the 

 Heat pafs off thro' it. This Fur- 

 nace (liould be about twenty Inches 

 deep, and twenty Inches fquare at 

 Bottom, but may be flop'd off on 

 every Side, fo as to be two Feet 

 and a half fqiiare at the Top-, and 

 under this Furnace fliould be a Place 

 for the Aflies to fall into, which, 

 fliould be about a Foot deep, and 

 as wide as the Bottom of the Fur- 

 nace j this fliould alfo have an Iron 

 Door to fliut as clofe as poffible; 

 but juft over the Afli-'Hole, above 

 the Bars, which fuppoit the Fuel, 

 fliould be a fcjuare Hole about four 

 Inches wide, to let in Air to make 

 the Fire burn; this muft alfo have 

 an Iron Frame, and a Door to fhut 

 clofe when the Fire is perfectly 

 lighted, which will make the Fuel 

 laft the longer, and the Heat will 

 be more moderate. 



The Top of this Furnace fnould 

 be nearly equal to the Top of the 

 Bark-bed, that the loweft Flue may 

 be above the Fire, fo that thero 

 may be a greater Draught for the 

 Smoak, and the Furnace fhould be 

 cover'd with a large Iron Plate, 

 clofely cemented to the Brick- work, 

 to prevent the Smoak from getting 



out!
