BLACK JACK. JACK OAK. 



Long island, New York, west through northern Ohio and Indiana to about latitude 55 N. in Wisconsin, 

 southern Minnesota, eastern Nebraska, Kansas, and the Indian territory to about 99 west longitude, south to 

 Matanzas inlet and Tampa bay, Florida, and the valley of the Nueces river, Texas. 



A small tree, sometimes 12 or even 18 meters in height, with a trunk rarely exceeding 0.60 meter in diameter, 

 or more often much smaller; dry, barren uplands, or often on heavy clay soils ; very common through the southern 

 states, and reaching its greatest development in southwestern Arkansas, Indian territory, and eastern Texas, 

 forming, with the post-oak (Q. obtusiloba), the growth of the Texas cross-timbers. 



Wood heavy, hard, strong, checking badly in drying; layers of annual growth marked by several rows of 

 large open ducts; medullary rays broad, conspicuous; color, rather dark rich brown, the sap-wood much lighter; 

 specific gravity, 0.7324; ash, 1.16; of little value except as fuel.
