 this genus ; but I must give a passing notice to the Black 

 Oak, because it is a common and very large tree in favor- 

 able situations. It has been named Black Oak on account 

 of the very dark color of its outer bark ; and YeUow 

 Oak, — a name quite as common as the other, — from the

 citron used by dyer^. It may also have been so called 

 from the yellowish leather-color of its leaves in the

 large trees of this species are found in the New England

 stitutes the principal timber of those extensive tracts 

 called Oak Barrens.
