This is one of our most important trees, and the wood is 
much used for wagons, carriages, handles, agricultural 
implements, etc. The wood is heavy, hard, strong, close- 
grained and flexible. The species grows in rich upland 
woods, and is common throughout the state. The- nuts are 
extensively gathered and sold in the market. Fuel is also 
obtained from this species.
