Shade Trees for Streets and Parks 109 



Red Oak (QiKrcits ruhra Linn.). 



Growing more rapidly than any other oak and possessing 

 a large symmetrical round or oval shaped crown, the Red Oak 

 is one of our best street trees. The deeply cut leaves, dark 

 green and glossy above and pale green beneath, turning red 

 in autumn, make this tree an object of beauty during the entire 

 summer and autumn. It is adapted to a variety of soils and is 

 one of the easiest and best to plant. 



Scarlet Oak (Qiicrcu* <<>(< in< a Mueneh.). 

 This tree is less extensively planted than either the Pin 

 Oak or the Red Oak. The round dome-like crown covered 

 with leaves which are a bright green and which are borne on 

 slender petioles and are thus allowed to respond to the faint- 

 est breeze forms one of the most attractive species of all the 

 trees found in our cities. The leaves turning to >a brilliant 

 scarlet in autumn add a touch of color to a street or park scene 

 which cannot be excelled. Unlike most other species are com-

White Oak (Quercus alba Linn.). 



This is the most stately and beautiful of our oaks and is 

 justly called the king of the forest. It is a vigorous tree grow-

 developed, broad crowned tree covered with bright green foli- 

 age is a most impressive sight. The red and russet colored 

 autumn leaves give it a splendor when the leaves of other trees 

 have fallen. The late shedding of leaves is often objectionable 

 since the walks are covered with litter which has to be re- 

 moved. It grows more slowly than either the Pin Oak, Red 

 Oak, or Scarlet Oak and grows best in a good loam soil. It 

 cannot be recommended before other members of the genus 

 which have been mentioned. 



The Lindens. 



American Linden (Tilia anuricana Linn.). 

 This tree is used quite largely as a shade tree because of 

 its rapid growth, its upright form and rounded outline and 

 its abundant light green foliage. The leaves are heart-shaped 

 and always one sided. The tree is subject to the attacks of 

 insects and the leaves are attacked by a fungus giving them
