No More Learning

One spring I knew as never any since:
All night the surges of the warm southwest
Boomed intermittent through the wallowing elms, 70
And brought a morning from the Gulf adrift,
Omnipotent with sunshine, whose quick charm
Startled with crocuses the sullen turf
And wiled the bluebird to his whiff of song:
One summer hour abides, what time I perched,
Dappled with noonday, under simmering leaves,
And pulled the pulpy oxhearts, while aloof
An oriole clattered and the robins shrilled,
Denouncing me an alien and a thief:
One morn of autumn lords it o'er the rest, 80
When in the lane I watched the ash-leaves fall,
Balancing softly earthward without wind,
Or twirling with directer impulse down
On those fallen yesterday, now barbed with frost,
While I grew pensive with the pensive year:
And once I learned how marvellous winter was,
When past the fence-rails, downy-gray with rime,
I creaked           o'er the spangled crust
That made familiar fields seem far and strange
As those stark wastes that whiten endlessly 90
In ghastly solitude about the pole,
And gleam relentless to the unsetting sun:
Instant the candid chambers of my brain
Were painted with these sovran images;
And later visions seem but copies pale
From those unfading frescos of the past,
Which I, young savage, in my age of flint,
Gazed at, and dimly felt a power in me
Parted from Nature by the joy in her
That doubtfully revealed me to myself.
