DESIGN 61 



permit of any change in the shape of the planting 

 areas or the width of the walks. 



In the informal type considerable changes of 

 outline may be made without materially altering 

 the general appearance. In Figure 13 the ar- 

 rangement of units is entirely dissimilar, and 

 yet the appearance in elevation would not vary 

 much. The charm of informal planting is closely 

 bound up in the silhouette of its elevation from all 

 different points of view; therefore the outline of 

 the plan of the planting masses seldom attracts 

 much attention. Accordingly the width of plant- 

 ing areas in informal design may often be consid- 

 erably changed, when necessary, without affecting 

 the general scale. 



The irregular boundaries of informal shrubbery 

 masses may easily be altered even to the extent of 

 moving them several feet to give greater freedom 

 of approach, or for some other utilitarian pur- 

 pose, without causing any marked change of ap- 

 pearance in the masses themselves. 



The formal type, where the whole garden 

 scheme is perceived at a glance, is successful or

 of the informal type lies largely in elevation. 



Since the final result of every design must be a
