THE FRUIT GARDENER. [B. II. 



Between the fore-mentioned plantations 

 and walls, fhould be made a belt of low 

 fhrubbry, walk, and border ; that t;he 

 walls may be covered on all fides with 

 fruit-trees. 



Brick is certainly the beft material for 

 the conftrudion of garden- walls 5 as being 

 both better adapted to training, and of a 

 more kindly nature for the trees, than 

 iloi^e : and where the wall is not entirely 

 compofed of brick, it fhould at lea ft be 

 lined*. But where theie cannot be pro- 

 cured, 



* We have hearomuch of late, concerning the pro- 

 priety of conftruding garden- walls of brick: I have 

 faid above, that brick is certainly the beft material. I faid 

 fo, in my firil edition of this work, five years ago j and 

 from every obfervation I have made, in a pretty ex- 

 tenfive practice, I venture to- hazard the fame opinion 

 now. That black whin-Jlone* is the next beft material, J 

 am fully perfuaded : not altogether becaufe that Hack 

 abforbs heat more than any colour, having proved black 

 bricks to be fuperior ; but that this fpecies of {tone- 

 is lefs porous than thofe of the free-ftone kinds. I have 

 moreover found, that although brick is more porous than 

 flone in general, and confequently, abforbs moifture 

 more readily j yet it alfo fooner expels moifture than 

 Hone of any kind. Perhaps, therefore, if we wifn to ar- 

 rive at the climax of perfection in this particular, we 

 ought to put our garden- walls in mourning !
