74 THE TREES OF NORTH CAROLINA. 



Nutt.) — Most common in the Middle and Western 

 States. I have not met with it in this State, and it 

 is introduced here on the authority of others. It 

 may be looked for only in the extreme western part 

 of the State, especially along the rivers flowing west- 

 ward. 



This may be distinguished from the preceding spe- 

 cies by its three pairs (sometimes four) of leaflets on 

 the common leaf-stem, and by the thick yellowish 

 shell of the nut, which is also ribbed on its upper 

 half, and has a strong point. The kernel is smaller, 

 and hardly so sweet as in the preceding. 



3. Common Hickory. (C. tomentosa, Nutt.) — 

 Found in all the States, and common in our own for-

 which occurs Jn the barrens. All the Hickories are 

 generally characteristic of a good soil, and this is no 

 exception only when it grows in the barrens, as it is 

 most vigorous in rich soils. It is about 60 feet high 

 and 18 to 20 inches in diameter. This species is 

 white to the heart, for which reason, probably, it is 

 called White Hickory in some parts of the State. The 

 other species have their wood more or less reddish. 

 The leaflets are from 7 to 9 (generally 7). The fruit 

 has a thick husk, splitting nearly to the base. The 

 nut is of various forms, but is somewhat six-angled, 

 of a light brown color, with a very thick shell and 

 small kernel. 



4. Pig-Nut Hickory. (C. glabra, Torr.) — Found 

 in most of the States. It is 70 to 80 feet high, scat-
