2o8 Trees with Compound Leaves. [D n 



A tree, fifty to eighty feet high, of great value. Its 

 tough and elastic wood is used in making agricultural 

 implements, carriages, axe-handles, etc. It ranks also 

 among the best of woods for fuel. Most of the " hickory 

 nuts " of the markets are from this species. 



All the Hickories are picturesque trees. Their 

 tendency, even when standing alone, is to grow high, 

 and with heads that, instead of being round, are cylinder- 

 shaped to the very top, with only enough breaks and 

 irregularities to add to the effect. This tendency is more 

 marked in the Hickories than in any other of the leaf- 

 shedding trees of North America. They are worthy of 

 the name sometimes given them of " the artist's tree."
