expended, as will be requifite when 

 the Walls are built after the manner 

 here directed : and where the Heat 

 is not pretty equally diftributed thro' 

 every Part of the Wall, fome of the 

 Treeswill have too much Heat, while 

 others will have little Benefit from 

 the Fires. 



There are fomePerfons who build 

 their Hot-walls in fuch a manner, as 

 to have the greateft Heat under the 

 Border, near to the Roots of their 

 Trees, fuppofing there is a Neceflity 

 of Heat to the Roots, as well as the 

 Branches : but this is a great Mittake; 

 for the Fires, fo fituated,muft great- 

 ly injure the Roots of the Trees, by 

 drying up the Moifture of the Earth, 

 as alio in fcorching the tinder Fi- 

 bres of thofe Roots which lie near 

 them. Therefore this Practice fhould 

 not be continued ; for it is much 

 the better Method to elevate the firft 

 Flue nine Inches, or a Foot, above 

 the Level of the Border, according 

 asthe Ground is dry or wet, than to 

 place it the leaft below - ground, 

 which will only dry the Earth, and 

 not warm the Air about the Trees, 

 which is the only Ufe of artificial 

 Heat : for it is very commonly pra- 

 dtis'd to draw a Branch of aVine, or 

 other Fruit-tree, into a Stove; which 

 Branch will produce its Fruit as 

 early as if the whole Tree had been 

 fore'd : when, at the fame time, all 

 the other Branches of thefameTree, 

 which are expos'd to the open Air, 

 will not be the leaft forwarded, tho* 

 they are all nourifh'd by the fame 

 Root : which is a plain Proof, that 

 there is no Neceflity of adding any 

 Warmth to the Roots of Fruit trees, 

 to have their Fruit earlier or better 

 ripen'd.. 



I have alfo heard of fome Walls 

 •which have been built for Forcing 

 of Fruit, with one continued Chafm 

 from their Bottoms to the Tops j fo 



that they have been like double 

 Walls, with Places at proper Di- 

 ftances to make the Fires : but thefe 

 can be of little Ufe ; for if theVents 

 are open at their Tops to let out the 

 Smoke, the Heat will alfo efcape 

 with it ; becaufe, if the Smoke be 

 not led about three or four times in 

 Flues, in order to warm the Bricks, 

 the Heat will pafs off at top, without 

 doing much Service to the Trees. 



Where the Walls are planted with 

 the beft Kinds of Fruit, which are 

 defign'd to ripen them in Perfection ; 

 if the Autumns mould prove cold, 

 or very wet, before the Fruit are 

 ripe, it will be proper to put the 

 Covers over the Trees : and if there 

 are fome flow Fires made to dry off 

 the Damps, it will be of great Ufe 

 to prevent the Fruit from growing 

 mouldy, and to haflen their Ripen- 

 ing. But when this is practifed, the 

 Covers fhould be taken off whenever 

 the Weather will admit of it, that 

 the Fruit may enjoy the Benefit of 

 the free Air, without which they 

 will be infipid or ill-tailed. 



Although in the former Directi- 

 ons for forcing Trees, in order to 

 have early Fruit, I have advifed,' 

 that fuch Trees fhould have one or 

 two Years Reft, in order to recover 

 Vigour ; yet that is not to be under- 

 ftood of thefe Trees, which are only 

 defign'd to be brought forward 

 enough to produce their Fruit in 

 Perfection : for, as the Fires are not 

 defign'd to be made till the Middle 

 or End of February 9 the Trees will 

 not befo much weakened therebyjbe- 

 caufe they will be enured to the open 

 Air long before their Fruit is ripe, 

 and will have time to ripen their 

 Shoots, and form their Buds, for the 

 next Year's Bearing : therefore thefe 

 Trees may be thus forced every Year, 

 without doing them any Injury, pro- 

 vided the/Trees are careful!yir.anag'd.
