106 Forest Cliib Annual 



serious pests. The tree is always rich in appearance, putting 

 forth its leaves early in the spring and is attractive in late 

 summer when most trees show the effects of heat and drouth. 

 The leaves turn a clear yellow before falling. 



Sycamore Maple (Acer pseudoplatanus Linn.). 

 This maple is also European but is not so desirable as 

 the Norway Maple since its crown is not so compact and the 

 tree is not so hardy. In appearance it is quite distinctive, 

 having large, dark green, thick leaves and long, reddish stems. 

 It is also subject to the attacks of borers which lessens its 

 value for street use. 



Sugar Maple (Acer saccharum Marsh.). 

 Hardy, erect and developing a compact crown of globular 

 outline, the Sugar Maple is an ornament on any street. When 

 set the trees should be from forty to forty-five feet apart to 

 allow for the proper development of the broad, round-topped 

 crown. The leaves grow profusely during the summer and in 

 autumn show beautiful coloring in yellow, orange and red. 

 The tree is not well adapted to a dry, hot climate and is not 

 so desirable as the Norway Maple for planting in the middle 

 west. 



Red Maple (Acer rubrum Linn.). 



This tree is less stiff and regular in its method of branch- 

 ing than the Sugar Maple, but grows a low, compact crown. 

 The bright scarlet flowers and fruit which appear in early 

 spring and the dark green foliage of summer make the trees 

 beautiful until the scarlet foliage of autumn makes it one of 

 the most attractive of any of our brilliantly colored trees. 

 It is seldom attacked by pests. When planted on streets the 

 trees should be placed about thirty-five to forty feet apart. 



Box Elder (Acer negundo Linn.). 



The Box Elder is native from Manitoba south and has a 

 wide natural range. Its ash-like foliage in summer and its 

 green branchlets in winter are the chief attractions. The tree 

 makes rapid growth and forms a compact rounded crown but 

 is short lived and very crooked except under the best condi- 

 tions. It is planted extensively through the middle west but 

 cannot be recommended where better species of maples will 

 grow.
