the Trees of long Continuance, be- 

 ing blighted every Spring; and in a 

 few Years were totally deftroyed : 

 and when the Branches of thofe 

 Trees, which grew upon the ftralt 

 Parts of the Walls, had extended 

 themfelves fo far, as to admit of 

 their being led into the circular Parts 

 of the Walls, they were conftantly 

 blighted and kill'd. 



When the Trees which had been 

 planted in the circular Parts were 

 deftroyed, the Walls were filled with 

 Vines ; but the Grapes of the fame 

 Sort were a full Month later than 

 thofe growing againft: the ftrait Parts 

 of the Walls ; fo that they rarely 

 ripen'd, which occafion'd their be- 

 ing rooted out, and Figs were after- 

 ward planted ; but the Fruit of thefe 

 fucceed little better ; nor can it be 

 fuppofed, that any Trees or Plants 

 will thrive fo well in thefe Circles, 

 when there is a conftant Draught of 

 Air round them, which renders the 

 Situation much colder than the open 

 free Air. 



I have alfo feen at Mr. Le Courts 

 Garden in Holland, fome Walls 

 built in Angles of different Forms ; 

 but thefe fucceeded no better than 

 the Circles before mentioned; for 

 I did not find one Tree in Health 

 againft the Walls ; nor did they pro- 

 duce Fruit. 



There are feveral other Schemes, 

 which have been propofed by dif- 

 ferent Perfons, for the building of 

 Walls to accelerate the ripening of 

 Fruits ; among which there was a 

 ! very ingenious Book written feme 

 : Years ago, intituled, Fruit-walls im- 

 fro<vd, by inclining them to the Hori- 

 [ z.on ; in which the Author has {hewn, 

 I by Calculation, that there will be a 

 much greater Number of the Rays 

 \ of the Sun fail upon fuch Walls, 

 ithan upon thofe ^hich are built per- 

 ipend.cular; and fremi thence has 



drawn Calculations, that Walls fa 

 built will be of great Service in the 

 accelerating of Fruit ; and has taken 

 the Trouble of calculating the dif- 

 ferent Inclinations, which fuch Walls 

 mould have in the different Climates, 

 in order to receive the greateft Num- 

 ber of the Sun's Rays. This Theory 

 feems to have all the Demchftration 

 neceffary for its Support ; but upon 

 Trial has not fucceeded in the lealt ; 

 for as thefe Walls muft be built 

 againft: Eanks of Earth, the Damps 

 which arife from the Ground over- 

 balance the Advantage of the Sun's 

 Rays: befide, thefe fioping Walls 

 being more expos d to the cold Dews 

 in the Night, the Fruit will be much 

 more chili'd thereby ; and in the 

 Spring the morning Frofts will prove 

 much more deftruclive to the tender 

 Bloffoms of the Fruit-trees, as they 

 will be more expbfed to them, than 

 againft an upright Wall : add to this 

 their being much more expofed to 

 the Winds and the Rain, and it will 

 be found, by comparing the Ad- 

 vantages propofed from thefe Walls, 

 with the Difadvantages to which 

 the Fruit-trees will be expofed, that 

 upright Walls will have the Prefer- 

 ence; for it is not the ftrongell Rays 

 of the Sun, in the Heat of Summer, 

 which is fo much wanting for ripen- 

 ing of Fruit, as the Continuance of 

 a moderate Share of Warmth ; and, 

 above all, the having of the Sun in 

 a Morning, to dry off the cold Dews 

 of the Night early, is of the greateft 

 Ufe ; which renders thofe Walls 

 which are built inclining to the Eait 

 preferable to South Walls ; as the, 

 Fruit will always ripen earlier againft: 

 them. 



There are fome Perfons who re- 

 commend the painting of Walls 

 black, or of a dark Colour ; as they 

 fuppofe the dark Colour will imbibe 

 more of the Sun's Rays, fo will re-
