 it vory difficult to split; on which account it is much used for making naves, er 

 hubs, in carriage wheels,— and also hatter's blocks. The younger trees, wiles

 leaves add greatly to the picturesque appearance of the country, by changing tea 

 bright crimson color. Four other species are enumerated in the U. States.
