But the Raven, sitting lonely on the placid bust, spoke only 
That one word, as if his soul in that one word he did outpour. 
Nothing further then he uttered- not a feather then he fluttered- 
Till I scarcely more than muttered, “Other friends have flown before- 
On the morrow he will leave me, as my hopes have flown before.” 
                Then the bird said, “Nevermore.”
