(C. laciniosa) resembles much in size and appearance the 

 common Shellbark ; but the nuts are double the size, the 

 shell much t k; cker and yellowish, while that of the latter 

 is white. It is but little known except west of the 

 Alleghanies. The Mockernut hickory (C. tomentosa) is 

 so called from the deceptive appearance of the nuts, 

 which are generally of large size, but contain only a very 

 small kernel. The leaves are composed of but four pairs 

 of sessile leaflets, with an odd one at the end. The trunk 

 of the old trees is very rugged, and the wood is one of the 

 best for fuel. 



The Bitternut hickory (C amara), sometimes called the 

 White hickory, grows 60 feet high in New Jersey. The 

 husk which covers the nut of this species, has four winged 

 appendages on its upper half, and never hardens like the 

 other sorts, but becomes soft and decays. The shell is 

 thin, but the kernel is so bitter that even the squirrels 

 refuse to eat it. The Water Bitternut (C. aquatica) is a 

 very inferior sort, growing in the swamps and rice fields 

 of the southern states. The leaflets are serrated, and 

 resemble in shape the leaves of the peach tree. Both the 

 fruit and timber are much inferior to those of all the other 

 hickories.
