 ranging from New York to Arkansas and Indian Territory. Prefers 

 bottom lands, and a rich moist soil. Varies from seventy-five to 

 one hundred feet high with a trunk two or three feet in diameter 

 which usually separates ten or fifteen feet from the ground into three 

 or four divisions which spread slightly and form a narrow pyramidal 

 head ; or when crowded by other trees, sending up one tall central 

 branchless shaft to the height of fifty or seventy feet. Branches 

 stout, pithy, and blunt ; roots fibrous.

Leaves. Alternate, bi-pinnately compound, ten to fourteen pin- 

 nate, lowest pinnae reduced to leaflets, the others seven to thirteen
