Read the excerpt from the poem "Faces in the Street" by Henry Lawson. Answer the question that follows.

And when the hours on lagging feet have slowly dragged away,
And sickly yellow gaslights rise to mock the going day,
Then flowing past my window like a tide in its retreat,

Ebbing out, ebbing out,
To the drag of tired feet,
While my heart is aching dumbly for the faces in the street.
