The Cork Elm is perhaps the most valuable tree of the 

 genus, as it possesses all the good qualities of the family 

 and none of the bad ones. It is strong, tough, easy to work, 

 takes a fine polisii, in short, is so useful that it is likely to be 



exterminated. Its range is 

 quite limited, extending 

 through northern New York 

 and southern Michigan to 

 Nebraska, Missouri, and mid- 

 dle Tennessee. It is some- 

 times called the Hickory Elm 

 and often the Cliff Elm. Its 

 leaves are about the size of 

 those of the ^Vhite Elm and 

 have the elm shape, unequal 

 at base, oval, doubly serrate 

 and acute. The tree may be known in the spring by the 

 raceme of drooping blossoms anil later by its samaras. But 

 at any time, the irregular cijrky ridges which grow from 

 every side of the branches and branchlets give the tree a 

 strange shaggy appearance and mark it unmistakably.
