 /'"/{jo/t-rj; greenish yellow ; growing in catkins. The staminate ones, three to 

 seven inches long; the pistillate ones growing in s|)ikes with from two to five

All undoubtedly know the pig-nut, for it is generally im- 

 pressed upon us by experience ; and to the mind clings the re- 

 membrance of early days when its nuts were eaten in error for 

 those of the good, old shagbark. Their bitter, disappointing 

 flavour vaguely touches the palate with the very name of pig- 

 nut. Throughout the northern states the tree is common and 

 well known. 



Commercially its strong, tough and flexible wood is not dis- 

 tinguished from that of the shell-bark hickories. For the 

 handles of tools, agricultural implements and the making of 

 many similar articles, it is useful.
