Analysis of At Sea

Three are emerald pools in the sea,
And wing-like flashes of light;
The sea is bound with the heavens
In a large delight.

Night comes out of the east
And rushes down on the sun;
The emerald pools and the light pools
Are darkened and done.

Our boat dips and cleaves onward,
Careless of night or of light,
Following the line of her compass
By her engines' might.

Through the desert of air and of water;
Like the lonely soul of man,
Following her fate to the ending,
Unaware of the hidden plan.

Sure only of battle and longing,
Of the pain and the quest,
And beyond in the darkness somewhere
Sure of her rest.
