138 PRACTICAL LANDSCAPE GARDENING 



affords a background and, in concealing the garden from without, 

 leaves something to the imagination and more to be appreciated 

 from a vantage point in the house. 



Garden enclosures may be of stone, brick, stucco or plants in 

 the form of a hedge. 



HEIGHT OF GARDEN ENCLOSURES 



The height of outer garden enclosures will vary according to 

 the surroundings. Where the outlook is not particularly attractive 

 they may be six or seven feet high. High walls are also a necessity 

 in some localities as a protection to the plants. Where it is thought 

 best to maintain views of the surrounding landscape a wall three to 

 five feet high is sufficient. Subordinate garden walls should not 

 be more than three to four feet high. On a smaU place, where the 

 scene must be made within the enclosure, a high wall is necessary. 



GARDEN WALLS 



When walls are adopted as an enclosure for the garden they 

 should always be of the same material as the house. If the house 

 walls are stuccoed the sides of the garden waU should also be stuccoed, 

 though, to provide a slight contrast, the piers and coping may be of 

 brick. This refers to gardens which are adjacent to residences. 

 When they are set apart, more or less isolated from the house, 

 the material may differ from that in the building. 



When walls of stone, brick, or stucco are used for the garden 

 enclosures they should be designed along artistic lines and be in 

 perfect harmony with the scene to be created. 



GRAV SANDSTONE WALLS 



Soft gray sandstone (Fig. 118) with an occasional marking of red 

 and orange is the most pleasing stone for the enclosing walls. These 

 should not be less than eighteen inches thick with a footing course 

 to project six inches beyond on each side, making a thickness of 

 thirty inches. The depth of the footing should not be less than 

 eight inches. The depth of the foundation below the frost Hne will 

 depend on the latitude. In Philadelphia and vicinity the founda- 

 tion should extend to a depth of three feet.
