and most generally distributed of tlie Hickory-trees in the south, and grows to its largest size in the 

 basin of the lower Ohio Kiver ^ and in Missouri and Arkansas. It is the only Hickory found in the 

 Pine forests of the sandy maritime Pine-belt of the southern states, where it is not rare, and with 

 the Pignut it grows in great abundance on low sandy hummocks close to the shores of bays and 

 estuaries along the coast of the south Atlantic and Gulf states. 



The wood of Hicoria alba is heavy, very hard, strong, tough, close-grained, and flexible, with 

 many thin obscure medullary rays and numerous large regularly distributed open ducts. It is a rich 

 dark brown, with thick nearly white sapwood. The specific gravity of the absolutely dry wood is 

 0.8218, a cubic foot weighing 51.21 pounds. Confounded commercially with the wood of the Shell- 

 bark Hickories, it is used for the same purposes. 



The abundance of this species ^ on the shores of Virginia and the other southern states probably 

 made it known to Europeans earlier than any of the other Hickories, and it was first described by 

 Parkinson in his Theatrwn Botanicum^ published in 1640.
