TREES TOLD BY THEIR FORM 



49 



massive crown, give the 

 elm an interesting and 

 stately appearance which 

 is unequaled by any other 

 tree. 



Range: Eastern North 

 America. 



Soil and location : The 

 elm prefers a deep, rich 

 and moist soil, but will 

 adapt itself even to the 

 poor soil of the city street. 



Enemies: The leopard 

 moth } a wood-boring in- 

 sect, and the elm leaf 

 beetle, a leaf-eating insect, 

 are the two most impor- 

 tant enemies of the tree. 

 Their ravages are very 

 extensive. 



Value for planting : 

 The tree has a character 

 of its own which cannot 

 be duplicated for avenue 

 or lawn planting. 



Commercial value : 

 The wood is strong and 

 tough and therefore has a 

 special value for cooper- 

 age, agricultural imple- 

 ments, carriages, and ship- 

 building.
