A tree belonging to the Walnut family, found only in North America. The wood is tough and elastic, and is largely used to make hoops for casks. Handspikes, carriage shafts, wheel spokes, handles of axes and golf clubs, large screws, etc., are made of it. The trunk is slender and has a very rough bark, and the tree grows to a height of from 60 to 100 feet. The hickory-nut has a delicious flavor. One southern species yields the esteemed pecan-nut, others yield the pig-nut, bitter-nut, and mocker-nut.
