TREES TOLD BY THEIR BARK OR TRUNK 59 



Form and size: It grows to large size. 



Range: Asia and Europe and naturalized in eastern 

 United States. 



Soil and location: Prefers moist places near streams 

 and ponds. 



Enemies: None of importance. 



Value for planting: The weeping willow has a special 

 ornamental effect in cemeteries and along lakes and river 

 banks in parks. 



Commercial value: It is used in the United States for 

 charcoal and for fuel. 



Comparisons: The pussy willow (Salix discolor) may 

 easily be told from the other willows by its small size; 

 it is often no higher than a tall shrub. Its branches are 

 reddish green and the buds are dark red, smooth and glossy. 

 The predominating color of the twigs and ])uds in the pussy 

 willow is therefore a shade of red, while in the weeping 

 willow it is yellowish green. 



GROUP VII. TREES TOLD BY THEIR BARK OR TRUNK: 

 SYCAMORE, BIRCH; BEECH, BLUE BEECH, IRON- 

 WOOD, AND HACKBERRY 



How to tell them from other trees: The color of the 

 hark or the form of the trunk of each of the trees in this group 

 is distinct from that of any other tree. 



How to tell them from each other: In the sycamore, 

 the bark is mottled; in the white birch, it is dull white; in 

 the beech, it is smooth and gray; in the hackberry, it is 

 covered with numerous corky warts; in the blue beech, the 

 trunk of the tree is fluted, as in Fig. 54, and in the iron- 

 wood, the bark peels in thin perpendicular strips.
