THE BAYBERRIES (MYRICACEiE). 



There are four arborescent species 1 of this family in the United 

 States, of which three are known to be attacked by sapsuckers, one 

 at least being sometimes in part or entirely killed. However, these 

 small trees have slight economic value and are little used for orna- 

 mental planting.

-THE walnuts and hickories (juglandace^:). 



Sapsuckers are known to attack 3 of the 5 native species of walnut 

 besides 1 introduced species, and 11 of the 14 native hickories. 

 Throughout their range hickory trees usually are severely attacked 

 by sapsuckers. We know of but one hickory being killed, but they 

 are often disfigured by swollen girdles. Sapsuckers cause much 

 staining and distortion in the wood of hickories.
