for planting, and where this is done for utility only without much con- 

 sideration in an ornamental point of view, the fence need not be all of 

 one description, but may be made of various materials, as may be found 

 most convenient and least expensive. For instance, it may be con- 

 structed of stone alone where this material is abundant on a certain 

 part of the Hne ; with wood alone in another part where stone is not so 

 convenient ; with posts and wire on a third part of the Hne ■frhere this 

 would be cheapest and perfectly serviceable, and so on.
