level of the baik-bed. Thcfe flues ought to be one foot 

 wide in the clear, that they may not be too foon ftopped 

 with the foot, as alfo for the more conveniently cleaning 

 them; the low-er flue, into which the fmoke firft enters 

 from the fire, fhould be two feet deep in the clear; this 

 (hculd be covered with broad tiles, which fnould be a 

 foot and a half fqiiare, that they may be wide enough 

 to extend over the wall in tront of the flues, and to take 

 fufficient hold of the back-wall ; over this the fecond 

 flue muft be returned back again, which may be eighteen 

 inches deep, and covered on the top as before, and fo in 

 like manner the flues may be returned over each other 

 fix or eight times, that the heat may be fpent before 

 the fmoke paflfes ofi^. The thicknefs of the wall in front 

 of thefe flues nee, not be more than four inches, but it 

 muft be well jointed with mortar, and pargitered within 

 fide, to prevent the fmoke from getting into the houfe ; 

 and" the outfide fhould be faced with mortar, and cover- 

 ed with a coarfe cloth, to keep the mortar from crack- 

 ing, as is praSifed in fetting coppers. If this be care- 

 fully done, there will be no danger of the fmoke enter- 

 ing the houfe, which cannot be too carefully guarded a- 

 gainft, for there is nothing more injurious to plants, 

 than fmoke, which will caufe them to drop their leaves, 

 and, if it continue long in the houfe, will entirely de- 

 ftroy them. 



The fire-place muft be m.ade at one end, where 

 there is but one ; but, if the ftove is fo long as. to re- 

 quire two, they ftiould be placed at each end of the flied, 

 which muft be made the length of the ftove, that the 

 fires and the hack of the flues may not fuffer from the 

 outer air, for it will be impoffible to make the fire burn 

 equally, where the wind has full liberty to enter, and it will 

 be troublefome to attend the fire in wet weather, where 

 it is expofed to the rain.
