This is a large tree, growing to the height of eighty feet, and about four feet in diameter. It is found in its greatest abundance east of the AUeghanies. It is not at all common in our Western States. It is called the toughest of the whole hickory genus, and is used where toughness and durability are most needed. The nut is small, roundish, ovate, hull very thin, and when ripe splits in the centre, and adheres to the nut after it has fallen from the tree. Kernel very small and usually bitter. It is only fed to animals, and is never marketable.
