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.
