Explanation:
Mary swims as well as her brother doed.
The answer would be political stability and economic growth
Oblique butterflyfish - Prognathodes obliquus
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!
