 from which the tree takes its name, oozes from the' 

 bark.

Found, from Connecticut to Illinois, and southward. It 

 reaches its finest growth and is very common in the 

 bottom lands of the Mississippi basin. 



A fine tree sixty to seventy feet high, or southward

 of seasoning it. It is sometimes used as a substitute 

 for Black Walnut. Its gum is used medicinally.
