GARDEN PLANNING 



The width between the uprights in a trans- 

 verse direction must be sufficient to preserve 

 a clear way of at least the width of the path, 

 and little is gained by making it wider. The 



Fig. 80. Pergola 



overhang of the cross timbers is useful when 

 it comes to training the plants, as the latter 

 tend to grow full at the top. At the same time 

 it pleases the eye. 



When it is desired to give architectural 

 significance to the pergola it is usual to make 

 the pillars of stone or brickwork, and to tie 

 them across with timber transoms, or to erect 

 a framework or roofing of worked timber over 

 the space. Such structures have no place 

 in a small garden, as they would be out of 

 scale compared with it.
