Shade Trees for Streets and Parks 111 



up. Tho re is no at tractive coloring and the tree is rather un- 

 cleanly because of the continual shedding of its bark. It is 

 adapted to most soils, enduring considerable moisture, but 

 requiring considerable light. 



Oriental Plane (Platanus oricntalis Linn.). 

 This tree possesses the desirable characteristic of rapid 

 growth together with other admirable features of good shade 

 trees. Is is hardy and forms a compact, rounded crown with 

 somewhat denser foliage than the American Sycamore. It is 

 free from fungus diseases and shows a very white skin when 

 the outer bark is shed. Because of the ability to shed its bark 

 the genus of planes is valuable for planting in locations where 

 soot and dirt are present. With the Ailanthus these trees 

 are well adapted to portions of cities where smoke and dust 

 abound. 



Horse-Chestnut (Aesculus hippocastanum Linn.). 

 This species is an object of beauty when the leaves first 

 appear in spring. The regular symmetrical, cone-like crown 

 is covered with a profusion of magnificent flowers which is 

 an ornament to any street or lawn. It is especially subject 

 to enemies and the leaves drop early when there has been a 

 period of drouth. Although the tree is tenacious of life it 

 can scarcely be recommended for extensive street planting 

 but may be used very well to a limited extent for park pur- 

 poses. 



'Tulip Tree (Liriodendron tulipifera Linn.). 

 The fine symmetrical form, straight trunk and conical 

 outline make this tree one of the largest and most beautiful 

 of all our trees. The leaves are unique, the "chopped off" 

 ends and glossy appearance giving them an individuality of 

 their own. Because the leaves have the fluttering habit of 

 the poplars it is often called Yellow Poplar. The color of the 

 wood gives it the name White-Wood ; while the resemblance 

 of the flower to the tulip gives it the name of Tulip Tree. 

 The tree is practically free from insect attacks but the ten- 

 dency to drop its leaves continually during the summer, the 

 brittleness of its branches and the difficulty in transplanting 

 it are objections to its use for street purposes.
