Question

Which of these excerpts from poems by Emily Dickinson uses irony? My cocoon tightens, colors tease, I'm feeling for the air; A dim capacity for wings Degrades the dress I wear. Could she have guessed that it would be; Could but a crier of the glee Have climbed the distant hill; Had not the bliss so slow a pace, — Who knows but this surrendered face Were undefeated still? One dignity delays for all, One mitred afternoon. None can avoid this purple, None evade this crown. There's a certain slant of light, On winter afternoons, That oppresses, like the weight Of cathedral tunes. Heavenly hurt it gives us; We can find no scar, But internal difference Where the meanings are. Exultation is the going Of an inland soul to sea, — Past the houses, past the headlands, Into deep eternity!

Answer 1

Exultation is the going
Of an inland soul to sea, —
Past the houses, past the headlands,
Into deep eternity!
i hope this helps

Answer 2

Well In my opinion, the whole poem is quite ironic - although she is mentioning the exultation and the royal color of death, the poem itself begins with the narrator saying that she cannot breathe - that she doesn't want to die.
So, I would say that the ironic parts are: 
Exultation is the going
Of an inland soul to sea, -
Past the houses, past the headlands,
Into deep eternity
