 to Michaux) ; the bark furrowed. Leaves 4-7 inches long and 2 - 3 $ inches wide, acute, 

 either cuneate or obtuse at the base, smooth above, paler and pubescent underneath ; the 

 teeth more numerous than in the preceding species : petioles 6-10 lines long. Peduncles 

 3-6 lines long, usually bearing two acorns : cup embracing about one-third of the nut ; the 

 scales appressed, very minute : nut an inch or more in length, somewhat pointed ; the kernel 

 sweet and rather pleasant. 



Rocky banks of the Hudson, particularly in the Highlands ; also on Lake Champlain, and 

 in the southwestern counties. Fl. May. Fr. Middle of September. The wood of thi.« 

 species much resembles that of the White Oak, but is heavier. It is also excellent fuel, being 

 not much inferior to hickory. The bark of the branches and smaller trunks is highly valued 

 by tanners.

Chemung county {Dr. Knieskern). My specimens are young, but I have little doubt of 

 their belonging to this species. The wood is yellowish, but little is known respecting its 

 mechanical qualities and durability.
