9. SCARLET OAK (Quercus coccinea). 



The Scarlet Oak, although hardy, has not been so exten- 

 sively used as either the Pin Oak or the Red Oak. Perhaps 

 this is because it requires rather a dry, well-drained soil. It 

 may be that fewer scarlet oaks are used for street trees be- 

 cause it has not been generally offered by nurseries. The 

 Scarlet Oak is not as attractive as the other two oaks during 

 the summer months but in the autumn it surpasses either 

 with its majestic coloring. It is long-lived, free from serious 

 pests and should be more commonly planted. 



10. WHITE OAK (Quercus alba). 



The White Oak is a noble, rugged, impressive tree. In 

 the fields and the forest it develops grand proportions, but 

 as a street tree it is not so desirable as the other oaks con- 

 sidered. It will grow fairly well in any soil, but good loam 

 furnishes the best condition for its successful growth, which, 

 at its best, is rather slow. The White Oak retains a large 

 proportion of its dead leaves during the winter. This is 

 considered objectionable by many lovers of trees. Insects 

 or tree diseases do not bother the White Oak to any great 

 extent. 



11. AMERICAN WHITE ASH (Fraxinus americana). 



The White Ash is the best of our native ash trees for street 

 planting. It forms a shallow root-system and makes the 

 be>t growth in low, moist soils. The ash makes a pleasing 

 tree with its compound leaves which do not appear too early 

 in the springtime to exclude the sunlight from the soil. Few 

 insects cause damage to the ash. It develops into a tall tree 

 with a pyramidal top with glossy light green leaves. 



12. RED MAPLE (Acer rubrum). 



The Red Maple makes a much more rapid growth than 

 the Xorway Maple and the Sugar Maple and produces a 

 softer wood. But it is not so easily injured by windstorms 

 as the Silver or White Maple to which it is superior for 

 street planting. It is a hardy tree and grows well in a rich, 

 moist soil. In other situations it does not make a very satis- 

 factory growth. The Red Maple is exceptionally attractive
