Read the passage. Ah, distinctly I remember it was in the bleak
December;
And each separate dying ember wrought its ghost
upon the floor.
Eagerly I wished the morrow; -vainly I had sought
to borrow
From my books surcease of sorrow-sorrow for the
lost Lenore-
For the rare and radiant maiden whom the angels
name Lenore-
Nameless here for evermore.
