THE BOOK OF FORESTRY 



THE WALTHJTS 



This family contains not only the black walnut and 

 butternut but also the toothsome shagbark, the mocker- 

 nut, etc. 



The walnut family can always be separated from the 

 hickory family by the fact that the pith in the former 

 is split into thin brown plates while the pith of the 

 hickories is solid. By cutting across a twig the family 

 can be determined, while the bark or leaves will separate 

 the walnut from the butternut. There are two other 

 walnuts in the United States one being found in 

 Colorado and New Mexico, the other in the California 

 coast region.
