 a trunk 0.90 to 1.20 meter in diameter; rich hillsides and sandy ridges; common and reaching its greatest 

 development west of the Alleghany mountains; varying greatly in the size and shape of the fruit. A form with 

 small, thin-shelled nuts (C. microcarpa, Nuttall I. c.) is not rare from Delaware southward, and in Michigan. 



Wood heavy, very hard and strong, tough, close-grained, compact, flexible; layers of annual growth clearly 

 marked with one to three rows of large open ducts; medullary rays numerous, thin; color, brown, the thin and 

 more valuable sap-wood nearly white; specific gravity, 0.8372; ash, 0.73; largely used in the manufacture of 

 agricultural implements, carriages, ax handles, baskets, etc. 



The sweet and edible nuts afford an important article of commerce.
