What poetic technique does henry wadsworth longfellow use in this excerpt from the poem "the day is done"?

the day is done, and the darkness
falls from the wings of night,
as a feather is wafted downward
from an eagle in his flight.

assonance

enjambment

iambic pentameter

consonance

The correct answer is enjambment.

Enjambment refers to the continuation of a sentence. it doesn't use punctuation and it doesn't have a pause beyond the end of a line or stanza. so this excerpt from the poem "The Day Is Done"The day is done, and the darkness 
Falls from the wings of Night, 
As a feather is wafted downward 
From an eagle in his flight uses enjambment. 

I hope this helped you.
