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

 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

 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 this 

 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.
