ARCADED WALKS AND PERGOLAS 157 



The pergola is garden architecture par excellence ; 

 it is not architecture in the garden, nor garden 

 products superimposed upon architecture — it is 

 the simplest form of construction completely con- 

 quered and possessed by plant and flower. Yet it 

 retains the qualities of architecture — the strength, 

 stability, and rhythm which proceed from regularity 

 in setting out, simplicity in design, and the repetition 

 of its ordered parts. It follows, then, that the pergola 

 can perform a most useful part in promoting the 

 marriage between house and garden, it carries a 

 structural significance with it, and wherever it can 

 be schemed as an appendage or prolongation of the 

 building itself it is of great value. This quality in 

 the pergola makes it important that it should not 

 stand alone ; like other garden features, it requires 

 connection with the salient lines of the design, and 

 more than they, it needs either a definite point of 

 departure, or a termination in a wall, garden house, 

 or gateway. It forms a light and beautiful substitute 

 for a building, wall, or cloistered walk, wherever a 

 lawn or terrace calls for such a background, and its 

 height and shadowed recesses give an air of shelter 

 and privacy in positions which otherwise would lie
