i)Tcadth of foundation might make the flues fettle unequal- 

 ly, and fo fpoil the defign. At the height of half a foot 

 above the furlace oi the ground muft be the firfl fine, that 

 there may be no damps, either below, or by the fide of the 

 flue, and that the earth in the border may not dry too 

 much, by the flues being below the furface of the border; 

 the depth of this flue fhould be two feet and a half, 

 the breadth cne foot, to be covered with two rows of 

 bricks 1 15 inches long, and of the ordinary breadth. 

 The advantage of having two rows ot bricks, is, that the 

 iron hooks, which are to be placed within three feet of 

 each other, and intended to fupport the trelaces, to which 

 the branchesof the Vines mufl be fixed, are firmer when 

 they have two ranges of bricks to hold by, than when ihey 

 have but one. The trelace projects three inches fiom ihc 

 wall, and thefe hooks murt be fixed in the back-wall, and 

 laid clofe under the brick-rov.'s that cover the flues, but 

 not fo as to impede the brooms in cleanfing the fines fjom 

 foot. In the back of the flue there mufl be one brick laid 

 neatly to the back of the wall, which being of ftone, and 

 the thicknefs two feet, the fame thicknefs may be carri- 

 ed to the top, that it may the better call: the heat for- 

 wards. The front of the flue is to be of the thicknefs 

 of an ordinary brick, or four inches; and the flues are 

 to be well laid over, both within, and without, with a 

 particular cement, as fliall be directed. 



The fecond fiue fhould be two feet deep; the third, one 

 foot and a lialf ; and the fointh, one foot ; whereby thefe 

 flues with tl'icir covers v/ill rife altogether to near ten feel 

 high, and one or two feet of topping, whereon the tim- 

 ber fliould be laid for the frames, with a proje6tion fix 

 inches over, under which the top-glafies are to run, that 

 the rain may fairly glide on iheir ouifide. Thefe flues 

 Hiould rife one above another, v/ith an inclination of 

 three inches it the contrary ends u here the fmoke en- 

 ters, for their better drawing and venting : and to be well 

 coated with firong plaifier <<n the outfide, of the moft 

 durable kind, which is of fincco ; as they mud be much 

 expofed ic the weather, when the rtoves are not lighted. 

 Great care is to be taken in the executing of thefe flues, 

 both as to rirength and neatncfs, to confine the heat, tor on 

 l!ic care of this execution, depends the whult- piotefs. I
