THE BLACK POPLAR. 
Populus nigra. 
PuatE 5, Fie. 2. 
OPLARS are all remarkable for 
rapidity of growth; and to this 
circumstance it is due in a large 
degree that their wood is not con- 
sidered to be—relatively to many 
other of our woodland Trees—of 
much value. As the four species which 
we shall proceed to describe have many 
features in common, we shall discuss these 
in the present chapter, leaving for the three sub- 
sequent chapters, notices of the peculiarities which 
distinguish their subjects from each other and 
from Populus mgra.
