THE HICKORIES, WALNUT AND BUTTERNUT 85 



Leaf: The leaf is compound, consisting of 5 or 7 leaflets, 

 the terminal one generally larger. 



Form and size: A tall, stately tree — the tallest of 

 the hickories — of rugged form and fine 

 symmetry, see Fig. 66. 



Range: Eastern North America. 

 Soil and location: The shagbark 

 hickory grows in a great variety of 

 soils, but prefers a deep and rather 

 moist soil. 



Enemies: The hickory hark borer 

 (Scolytus quadrispinosus) is its principal 

 enemy. The insect is now killing 

 thousands of hickory trees in the vicin- 

 ity of New York City and on several 

 occasions has made its appearance in 

 large numbers in other parts of the 

 country. 



Value for planting: It is difficult 

 to transplant, grows slowly and is seldom 

 found in nurseries. 



Commercial value: The w^ood is 

 extremely tough and hard and is used 

 for agricultural implements and for the 

 manufacture of wagons. It is excellent 

 for fuel and the nuts are of great value 

 as a food. 



Other characters: The fruit is a nut 

 covered by a thick husk that separates into 4 or 5 seg- 

 ments. The kernel is sweet. 



Other common names: Shellbark hickory.
