THE SURFACE.

in leaf, flowers, and forms, for the sake of contrast, and 

 to place those with beautiful foliage and habits, near the 

 house, and other conspicuous places. 



Sometimes undulated borders may be employed to ad- 

 van tage in another way. A case of a two-acre garden on a 

 corner, where there w^as a continuous fall in the streets in 

 a south and eastern direction, amounting to about fifteen 

 feet, may be used to illustrate. It was considered desirable, 

 owing to the natural 

 lay of the land, to keep 

 the surface of the gar- 

 den nearly level, not- 

 withstanding the fall in 

 the street. Figures 16, 

 17, 18, representing 

 cross sections of the 

 boundary undulations 

 at these points, namely, 

 where the street was a 

 little higher than the 

 general garden level, 

 (figure Iti). Where it 

 was uniform with it 

 (figure 17), and where 

 considerably lower (fig- 

 ure 18), will explain 

 how the case was satis- 

 factorily managed; the ^^S- 19.-plan or mound for trees. 

 dotted lines in the engraving representing the garden 

 surface. From the interior of the garden, hardly any idea 

 of the descent outside, or of the streets themselves, can 

 be gathered, which in this case was desirable, owing to 

 the heavy traffic going on through one of them. 



Another effective style of surface variation sometimes 

 introduced, consists of one or more mounds somewhat 

 centrally located, and away from house and boundaries
