An excerpt from Walt Whitman’s superb Sea-Drift, written in 1859, about alone-ness and becoming a poet.

Out of the Cradle Endlessly Rocking

Out of the cradle endlessly rocking,
Out of the mocking-bird’s throat, the musical shuttle,
Out of the Ninth-month midnight,
Over the sterile sands and the fields beyond, where the child
leaving his bed wander’d alone, bareheaded, barefoot,
Down from the shower’d halo,
Up from the mystic play of shadows twining and twisting as if they
were alive,
Out from the patches of briers and blackberries,
From the memories of the bird that chanted to me,
From your memories sad brother, from the fitful risings and fallings I heard,
From under that yellow half-moon late-risen and swollen as if with tears,
From those beginning notes of yearning and love there in the mist,
From the thousand responses of my heart never to cease,
From the myriad thence-arous’d words,
From the word stronger and more delicious than any,
From such as now they start the scene revisiting,
As a flock, twittering, rising, or overhead passing,
Borne hither, ere all eludes me, hurriedly,
A man, yet by these tears a little boy again,
Throwing myself on the sand, confronting the waves,
I, chanter of pains and joys, uniter of here and hereafter,
Taking all hints to use them, but swiftly leaping beyond them,
A reminiscence sing.

Once Paumanok,
When the lilac-scent was in the air and Fifth-month grass was growing,
Up this seashore in some briers,
Two feather’d guests from Alabama, two together,
And their nest, and four light-green eggs spotted with brown,
And every day the he-bird to and fro near at hand,
And every day the she-bird crouch’d on her nest, silent, with bright eyes,
And every day I, a curious boy, never too close, never disturbing
them,
Cautiously peering, absorbing, translating.
Shine! shine! shine!
Pour down your warmth, great sun.’
While we bask, we two together.
Two together!
Winds blow south, or winds blow north,
Day come white, or night come black,
Home, or rivers and mountains from home,
Singing all time, minding no time,
While we two keep together.
Till of a sudden,
May-be kill’d, unknown to her mate,
One forenoon the she-bird crouch’d not on the nest,
Nor return’d that afternoon, nor the next,
Nor ever appear’d again.
And thenceforward all summer in the sound of the sea,
And at night under the full of the moon in calmer weather,
Over the hoarse surging of the sea,
Or flitting from brier to brier by day,
I saw, I heard at intervals the remaining one, the he-bird,
The solitary guest from Alabama.
Blow! blow! blow!
Blow up sea-winds along Paumanok’s shore;
I wait and I wait till you blow my mate to me.
