1. Shell-Bark Hickory. (Carya alba, Nutt.) — 

 This is not abundant in any part of the State, and 

 least of all in the Lower District. It grows upon 

 the rich lands on and near watercourses. It is much 

 more common in the Northern States than in the 

 Southern. It is 60 to 80 feet high, with a dispropor- 

 tionate diameter of 15 to 20 inches for three fourths 

 of its length. The narrow strips of outer bark loos- 

 ened from the trunk, attached only by the middle, 

 while the two ends are bowed outwards, which char- 

 acterize this and the next species, are observable 

 only on stocks that exceed 10 inches in diameter and 

 are 8 to 10 years old. But the leaflets are almost 

 uniformly in two pairs, (rarely three,) with an odd 

 one at the end of the common leaf-stem. The nuts 

 are nearly pointless, and with a thin white shell. 

 They are the finest nuts we have, excepting perhaps 

 the Pecan Nut (C. olivseformis), of the Southwestern 

 States.
