92 THE TREES OF NORTH CAROLINA. 



country. In the most favorable situations with us, 

 it is not often seen above 60 or 70 feet high ; but in 

 some sections, as in the Middle States, it reaches the 

 height of 100 feet, and a diameter of 4 or 5 feet. 

 The timber of this tree is not in much demand, but 

 is occasionally used by wheelwrights for the naves 

 of wheels, where other material cannot be obtained. 



There is a difference in the spread of this tree, the 

 form with drooping branches being much more grace- 

 ful and showy than the one with more erect branches. 

 It is much to be regretted that this is generally so 

 crowded in our streets as to prevent its attaining its 

 widest spread, and its most natural and attractive 

 form. 



2. Small-Leaved Elm. (U. alata, Michx.) — Gen- 

 erally known in this State by this name, but more 

 commonly known elsewhere, perhaps, as Wahoo. It 

 is not uncommon with us, except on the higher 

 mountains. Its Northern limit is in lower Virginia. 

 It is only 30 to 45 feet high, not only smaller, but of 

 much less graceful form than the preceding, though 

 often seen as a shade tree in our streets. It is readily 

 distinguished by its much smaller leaves, and by the 

 corky excrescences which, as in the Sweet Gum^ 

 wing the smaller branches. 



The wood is more compact and finer grained than 

 in the former species, and is used for the naves of 

 wheels, for which some prefer it to Black Gum. 



A variety of this occurs, in which the excrescences 

 are wanting, and the branches more slender and
