 "yellow poplar." It is one of the most satisfactory shade 

 and ornamental trees. 



An interesting study of trees is to trace the annual

 operations and after one has counted the age of a branch 

 by observing the rings on the bark he can cut across 



the limb and count the annual wood layers. Of course,

 by the bud scales and one cannot usually trace the
