 throughout the forest and the average size is small. The shppery 

 elm tree grows to a height of from 60 to 70 feet, with a trunk rarely 

 more than 2 to 2^ feet in diameter. The range of cork elm is much 

 more limited than that of white and shppery elm (fig. 3). It does 

 not extend farther south than Tennessee, and throughout a large part 

 of the region of its distribution it is not important commercially. 

 The tree attains a height of from 80 to 100 feet and a trunk diameter

 and northeastern Texas, where it grows to a maximum height of 

 90 feet and a maximum trunk diameter of about 3 feet. It is fairly 

 abundant in some locahties in Texas.
