42 ROSES FOR ENGLISH GARDENS 



all be considered ; indeed in this, as in the very 

 smallest detail of procedure in garden design, just 

 the right thing should be done or it is better let 

 alone. 



In small gardens in which there is no general 

 design there often occurs some space where one 

 department gives place to another — as when flower 

 garden adjoins vegetable ground — where a short 

 pergola-like structure of two or three pairs of posts 

 may be quite in place and will form a kind of deepened 

 archway. Such an arrangement in iron is shown in 

 the illustration, where it makes a pleasant break in an 

 awkward corner where there is a mixture of wall and 

 flower border and a turn of the path. 



The pergola proper should be always on a level 

 and should never curl or twist. If a change of 

 level occurs in its length in the place where it is 

 proposed to have it, it is much better to excavate and 

 put in a bit of dry wall right and left and steps at the 

 end, either free of the last arch or with the last two 

 pairs of piers carried up square to a higher level, so as 

 to give as much head-room at the top step as there is 

 in the main alley. 



There is a great advantage in having solid piers of 

 masonry for such structures ; piers of fourteen-inch 

 brickwork are excellent, and in some districts even 

 monoliths of stone can be obtained ; but often the 

 expense of stone or brickwork cannot be undertaken 

 and something slighter and less costly must be used. 

 The illustration of a Wistaria pergola is the more 

 instructive because the structure shown is only a few
