SECTION XXXVI. FOREST TREES (Continued) 



IF a wire is stapled to a tree, it will not be pushed 

 outwards as the tree grows larger, but will be buried under 

 the new layer of wood (Fig. 137). It thus cuts into and 

 injures the lumber. Fig. 138 shows a better way to attach 

 a fence wire to a tree. 



Planting trees on the school grounds. When the 

 school ground needs shade and beauty, plant trees and 

 pretty shrubs taken from the woods. Set aside one day as 

 "Arbor Day" for the planting of these trees. In the 

 Southern states a good time for this is in December, 

 January, and February. Plan what kinds of trees and 

 shrubs to plant and where to put every one in order to 

 make the school grounds as beautiful as possible. They 

 will live better if not planted on the playground, where the 

 shaking will dry the roots. If planted there, they should 

 be protected by strong stakes until the trees are several 

 years old. The directions given in Section XXXVII for 

 setting fruit trees will help in setting shade trees. 



Choose some of the following for planting on the school 

 grounds : the water or willow-leaved oak as a round-topped 

 shade tree, suited even to poor, dry soils ; the sweet 

 gum, for its rapid growth, graceful shape, its willingness

 leaves in autumn ; the mulberry for its rapid growth, good
