124. The Gardener's New Director. 



ufe of a furnace invented by Mr. yames Scot at Turnham 

 Green near London, charged three-pence per pound ; to 

 vvhicli mufl: be fitted a UToi!p;ht iron door, hooks, and 

 a latch, to be fixed in the oven, which mull; be fuit- 



ed 



placed, in which there fhould be a groove made for 

 the glafles to flide into ; the dimenfion of the doping 

 timbers fhould be ten inches by nine, of yellow fir, and 

 the crown plate one foot bv nine or ten inches, of the 

 fame timber. The wall in the back part of the ftove 

 fhould be at IcalT: thirteen inches thick, but eighteen or 

 twenty-two inches, which is two bricks and a half, will 

 do better, for the greater thicknefis there is in the back- 

 wall, the more heat will be thrown to the front, where- 

 by the air of the ftove will be better warmed, and the 

 building will be fp much ftronger, for to this back-wall 

 the iiues, through which the fmoke is to pafs, muft be 

 joined. This back-wall fliould be carried up about fix- 

 teen feet high, or more for tall ftoves, that they may be 

 of a proper height to fupport the timbers of the back- 

 roof, which covers the flied behind the ftove. This roof 

 is faftened into the crown-piece before-mentioned, which 

 m tall floves fhould be about thirty feet above the fur- 

 face of the lan-bed, which will give a fufficient declivi- 

 ty' to the doping glaffes to carry off the wet, and be of 

 a reafonable height for containing many tall plants. The 

 back-roof may be flated, covered with lead, or tiled, 

 according to the fancy of the owner, but the manner of 

 the outfide budding is better expreffed by the annexed 

 plan, than is poflible to be defcribed in words. 



In the front of the houfe, before the tan-bed, there 

 fhould be a walk, about two feet wide, for the conve- 

 niency of walking ; next to which the bark-pit muft be 

 phiced, which fhould be in width proportionable to the 

 breadth of the houfe. If the houfe is fourteen feet 

 wide, which is a due proportion, tlie pit may be eight 

 feet wide, and behind, the pit fliould be a walk two feet 

 wide, to pafs, in order to water the plants, l^c. then 

 there will be two feet left next the back-wall, to 

 treft the flues, which mull: be all raifed above the 



level
