BLACK WALNUT. 



Western Massachusetts, west along the southern shores of lake Erie through southern Michigan to southern 

 Minnesota, eastern Nebraska, and eastern Kansas, south to the Chattahoochee region of northern Florida, central 

 Alabama and Mississippi, and the valley of the San Antonio river, Texas. 



A large tree, often 30 to 45 meters in height, with a trunk 1.80 to 3 meters in diameter ; rich bottom lands 

 and hillsides ; most common and reaching its greatest development on the western slopes of the southern Alleghany 

 mountains and in the rich bottoms of southwestern Arkansas and the Indian territory; less common east of the 

 Alleghany mountains, and now everywhere scarce. 



Wood heavy, hard, strong, rather coarse-grained, liable to check if not carefully seasoned, easUy worked, 

 susceptible of a beautiful polish, durable in contact with the soil, containing numerous large, regularly-distributed, 

 open ducts; medullary rays numerous, thin, not conspicuous; color, rich dark brown, the thin sap-wood much 

 lighter; specific gravity, O.Gllo ; ash, 0.79; more generally used in cabinet-making, interior finish, and for gun 

 stocks than that' of any other North American tree.

 neighborhood of San Francisco bay and the valley of the Sacramento river. 



A tree rarely 15 to 22 meters' in height, with a trunk 0.30 to 0.90 meter in diameter, reaching its greatest 

 development in the neighborhood of San Francisco bay ; in Texas generally reduced to a low, much-branched 

 shrub : borders of streams and mountain caiions, in rich soil. 



Wood heavy, hard, not strong, coarse-grained, checking in drying, susceptible of a good poli.sh, containing 

 numerous regularly-distributed, large, open ducts ; medullary rays distant, thin, obscure ; color, rich dark brown, 

 the sap-wood lighter; specific gravity, 0.0554 ; ash, 1.01. 



The small nuts sweet and edible.
