TREES THEIR PLANTING AND CARE. 67 



and golden poplars. The foliage of trees like the golden 

 poplar, maple, or elm will be injured in effect if planted in 

 contrast with trees of a bluish or very glaucous color, while 

 trees with showy flowers will be made more conspicuous if 

 planted with a mass of dark-colored foliage for a back- 

 ground. 



4. Specimen trees, i.e., those that stand out on the lawn 

 conspicuously, should be those of characteristic beauty. 

 The oak has the characteristic beauty of strength ; the elm 

 that of graceful, arching form; the purple beech, Nord- 

 mann's fir, and the Colorado blue spruce great beauty of 

 coloring; the cut-leaved weeping birch and Japanese weep- 

 ing cherry the beauty of graceful, flowing outline; and each 

 and all of the more common ornamental trees have some 

 characteristic beanty which it should be the study of the 

 landscape artist to bring out in grouping them together. 



5. Groups should not be planted so as to present a too 

 solid appearance, and if arranged so as to give each speci- 

 men its proper distance and setting there will be little 

 danger of this result. To still further lighten up a group 

 that has a teudency to too much compactness, small isolated 

 specimens in the lawn at a little distance from the outside 

 tree may be planted, as shown in Figs. 27 and 28. 



6. Where the surface of the lawn is rolling, instead of 

 arranging the trees, as in Fig. 29, much better effect will be 

 produced by dividing the group, as shown in Fig. 30. In 

 this way a much smaller number of trees will give more real 

 beauty to the grounds than if all were planted in a line or 

 a close group. 



7. When planting along walks or drives, an effort should 

 be made to group as naturally as possible and, if the 

 curve of the walk or drive is made to extend around and
