Fig. 4 is a section of a flnel wall built solid, the flues being 

 placed at different distances from the south side of the wall (on 

 the right of the engraving), — greater at bottom, as there -will 

 be the moat heat, and nearer at top, and correspondingly nearer 

 between, as the heat will be less upwards.

■ These are the only deseriptione of hot walls that I have seen 

 Tised advantageously ; and those I have worked built in accord- 

 ance with " Bob's " section I have found more injinious than 

 serviceable in any way. The cost of these walls is about equal, 

 the latter, fhi. 4, being the most expensive of the three. It is 

 built plumb! The two first slope inwards ; and in this I see an 

 advantage, as tho trees get many a refreshing shower, whilst 

 those on a perpendicular wall get little rain, and are, besides, 

 often surmounted by a coping projecting several inches, the 

 utility of which I have striven to discern and have not been 

 able.

Whilst writing about walls I will take tho opportnnity'of 

 saying, that of all the walls I have had to deal with none soir 

 passed that shown inyiy. 5, it being 12 feet above the ground 

 level, and built pigeon-holed from top to bottom, which is a 

 great saving of material ; and an equally strong wall is secured 

 as if built solid, and not so liable to give way as a narrower one, 

 though taking the same quantity of bricks. Such a wall for 

 the southern wall of a garden is desirable. It should be 18 inchec 

 thick and 14 feet 6 inches high, including foundation, and its 

 cost about 4s. per superficial yard ; so that a wall of thig ^^ 

 scription 272J feet long will 

 cost £110. 



Fig. 6 is a brick-and-a-half or 

 14-inch wall, 12 feet from the 

 foundation and 10 feet from the 

 ground level. On solid ground 

 the foundation may be nearer 

 the surface, and the wall have 

 12 feet of available surface for 

 training trees ; and its cost 

 would be for a wall 160 feet 

 long £30, at 4s. 9d. per super- 

 ficial yard. Such a wall is suit- 

 able for the east and west sides. 

 To enclose a garden, therefore, 

 with walls is a very costly affair. 

 Suppose the garden were two 

 acres in extent, it would bo best 

 disposed of in the form of a 

 parallelogram, having an equal 

 area within as without the walls. 

 To wall round a garden 272i 

 feet by 160, thus containing ex- 

 actly an acre, and this is a nice 

 proportion, giving a large ex- 

 tent of south wall, or walls run- 

 ning from east to west, coneequently facing south, the cost 

 would be as follows : — ,

South wall, as Jl J. 5 Ill) " 



West and east walls, as ^^. 6 lOO , ; -^4

If the east and west walls were built the same as the south wall, 

 then the cost would be £22 more, or £457 ; and if instead of a 

 flued wall to the north, one the same a.s fig. 5 were built and 

 continued all round, the cost would be reduced to £342 for th* 

 enclosing of a garden containing an acre within the walls. 

 This may seem a very large sum ; but it is not so large by £95 

 as Mr. Thompson states in the " Gardener's Assistant " by the 

 most expensive plan here given, nor so much by £210 accord- 

 ing to the last (all built hke.rt;;. 5j, plan. The prices are those 

 of work done, but the price varies with the expense of materials, 

 distance of cartage, and the rate of wages. _ , ; 



I have known instances of the east and west walls being 

 flued, which to me seems a waste of material and labour, s 

 thicker wall being necessary. With glass so cheap as it is, it 

 really seems a waste of money to build walls, and especially 

 flued walls, beyond those necessary for protection ; and for this 

 14-inch walls and 12 feet high above the ground are as thick and 

 as high as need be. More money has been often wasted on hot 

 walls and thick walls than would have built a very nice range 

 of forcing-houses ; and fruit can be grown with much greater 

 certainty in them than on walls however artificially heated- 

 I am no advocate of flued walls, but I have seen finer end 

 heavier crops of fruit — Peaches, Nectarines, and Apricots, on 

 them than in all the unbeated dt-tacbed houses I have yet seen. 



Another subject I should like to broach, and that is, the de- 

 voting of south walls exclusively to reaches;. Nectarines, and 

 Apricots ; or, where there is a large extent of wall, one or two 

 Plums and Cherries may be planted, but this is the exception. 

 It seems strange that, the best aspect should be exclusively 

 devoted to that which lasts in season but a short time, some 

 having a notion that any aspect is good enough for Pears and 

 Plums. I confess most Pears and Plums do fairly on west 

 aspects ; but I must say that the fiuer kinds, fine as they are on 

 west aspects, are much finer when grown on a south aspect. 

 If we are to derive any benefit from cheap glass, it must be in 

 employing it for the growth of those fruits that are not un- 

 exceptional grown on walls ; but though the fact is, that those 

 fruits not bearing with certainty and to perfection on walls will 

 do BO if the wall be covered with ghiss, it really givee no one
