Hi hi I need some help for a poem by Emily Dickinson. I've gotten one done but I cant find any more. I've provided to poem below "Hope" is the thing with feathers-
That perches in the soul-
And sings the tune without the words-
And never stops- at all-

And sweetest - in the Gale- is heard-
And sore must be the storm-
That could abash the little bird
That kept do many warm-

I've heard it in the chillest land-
And on the strangest Sea-
Yet- never - in Extermity
It asked a crumb - of Me.

Question: what are 4 extended metaphors in 'hope is the thing with feathers'?
