THE BOOK OF GARDENING. 



Two or more walks and paths need not in their forms follow 

 definite shapes, as the delineation of such would be hidden by 

 the plantations. One alley must not run into another at right 

 angles, but their axes, as I have said before, must join har- 

 moniously. It must (Fig. 21) join obliquely after such an angle 

 that the direction of B may be taken naturally, but at the same 

 time one should also be able to turn with ease towards G if one 

 chooses to take that direction. When an alley (A) divides, each 

 of the two branches (B and C) must take at once a decided 

 opposite direction in order not to leave any doubt about its 

 destination (Fig. 21). Such a disposition as that shown in 

 Fig. 22 must be avoided. The separation is seen at once to 

 be unnecessary; as the two branches show that they will meet 

 again at a short distance.

In the formal garden the alleys not only characterise but create 

 the kind of garden. Their turfed grass borders, flower-beds, 

 terraces, &c, must be in strict harmony with the architectural 

 lines of the house, arid the former must have their axes in 

 common with the latter. There must be a marked delineation 

 of the limits of the formal and the landscape garden, in the 

 form of balusters, steps, or banks. 



If the formation of the drives, walks, and paths is very 

 carefully attended to, it will afterwards be much easier to keep 

 them in good order. The lines forming the widths of the drive 

 must be well defined, and that width dug out. The depth 

 of the depression and the thickness of the road material 

 depend on the use to which the road is intended to be put. 

 A main drive, on which there is likely to be a lot of carriage traffic, 

 must be made as solid, and maintained in the same 

 condition, as a public road ; it will require a layer of broken 

 stones or rough gravel 6in. to loin, thick. Other kinds of
