32 LANDSCAPE GARDENING. 



If the covering of soil is over only a part of the roots of 

 the tree, as in Fig. 11, the roots coming to the surface on 



FIG. 11. ILLUSTRATES COVERING THE ROOTS ONLY ON ONE SIDE. 



one side, little injury need be feared unless there is a great 

 depth of soil about the trunk, in which case the " well " 

 should be made. 



It is very difficult to make grass grow to great perfection 

 under the shade of trees and where the tree-roots fill the 

 ground, and the main dependence must be on surface-dress- 

 ing with rich soil or compost and frequent seeding. 



The Lawn. 



Upon no one thing does so much depend in making 

 beautiful home grounds as upon a good lawn, and after 

 the buildings and the preliminary grading are completed 

 come the smoothing up and preparation of the soil for the 

 grass carpet or " groundwork " of the home-picture, with- 

 out which no picture, whether on canvas or made of living 

 plant-growths, is complete. 



A good lawn cannot be made except on a rich soil, 

 and if this is not the natural character of the land in 

 hand the first thing to do is to make it rich and as deep 

 as possibly.
