4 THE OECHAED AND FEUIT GAEDEN, 



will be injured and impoverished, and their fruit spoiled. 

 The digging must be managed with reference to the 

 roots of the trees, and no crop must be put in so close 

 to a tree as to interfere with it either while it grows or 

 in its removal. The manure, too, must not be given to 

 the vegetables without regard to the prosperity of the 

 trees ; it must on no account be given close round the 

 roots at a season when forcing them would encourage 

 rampant growth to the detriment of a fine crop of fruit, 

 nor withheld from them when mulching is requisite or 

 beneficial. 



Fruit and vegetables, or fruit and orchard crops, may 

 do well in concert if all are fairly treated, and fairly 

 enriched, but for the production of choice fruit it should 

 be made the specialite in either the orchard or the 

 garden. 



For fencing, there is nothing that may be compared 

 with fine, smooth, high walls, as available for the train- 

 ing of the best kinds of fruit, and a safeguard against 

 the depredations of thieves. Next to these in merit, 

 though far inferior, stand well-made, close wooden fences, 

 and these are about the only methods of enclosure to be 

 used with advantage for orchards or fruit gardens. 



A wall should be at least eight feet high, and as much, 

 higher as can be made convenient. If not more than 

 eight feet, it may be nine inches in thickness. From 

 eight to fourteen feet high requires thirteen inches and 

 a half in thickness, and above that height eighteen 

 inches. A wall, if high and many feet in length, must be 

 strengthened with buttresses, and the foundation of all 

 walls should be a brick and a half thick, even where the 

 wall itself is only one brick thick. 



Plued or hot walls are built hollow, the interstices 

 being used as flues for the circulation of artificial heat. 

 It is necessary for these walls to have hooks along, near 

 the top, under the coping, or other apparatus for arrang- 

 ing protection over the trees when necessary. 



A wall like this will require a fire to every forty or 

 fifty feet of wall. Stone walls are good, but they almost 

 require a lattice over them to which to train trees.
