# Now as I was young and easy under the apple boughsAbout the lilting house and happy as the grass was green,The night above the dingle starry,
|
|
# Time let me hail and climb Golden in the heydays of his eyes,And honoured among wagons I was prince of the apple towns
|
|
# And once below a time I lordly had the trees and leaves Trail with daisies and barley Down the rivers of the windfall light.
|
|
# And as I was green and carefree, famous among the barns About the happy yard and singing as the farm was home,In the sun that is young once only,
|
|
# Time let me play and be Golden in the mercy of his means,And green and golden I was huntsman and herdsman, the calves
|
|
# Sang to my horn, the foxes on the hills barked clear and cold,And the sabbath rang slowly In the pebbles of the holy streams.
|
|
# All the sun long it was running, it was lovely, the hay Fields high as the house, the tunes from the chimneys, it was air And playing, lovely and watery
|
|
# And fire green as grass. And nightly under the simple stars As I rode to sleep the owls were bearing the farm away,
|
|
# All the moon long I heard, blessed among stables, the nightjars Flying with the ricks, and the horses Flashing into the dark.
|
|
# And then to awake, and the farm, like a wanderer white With the dew, come back, the cock on his shoulder: it was all Shining, it was Adam and maiden,
|
|
# The sky gathered again And the sun grew round that very day.o it must have been after the birth of the simple light
|
|
# In the first, spinning place, the spellbound horses walking warm Out of the whinnying green stable On to the fields of praise.
|
|
# And honoured among foxes and pheasants by the gay housender the new made clouds and happy as the heart was long,In the sun born over and over,
|
|
# I ran my heedless ways,My wishes raced through the house high hay And nothing I cared, at my sky blue trades, that time allows
|
|
# In all his tuneful turning so few and such morning songs Before the children green and golden Follow him out of grace,
|
|
# Nothing I cared, in the lamb white days, that time would take mep to the swallow thronged loft by the shadow of my hand,In the moon that is always rising,
|
|
# Nor that riding to sleep I should hear him fly with the high fields And wake to the farm forever fled from the childless land.
|
|
# Oh as I was young and easy in the mercy of his means,Time held me green and dying Though I sang in my chains like the sea.

# When to the sessions of sweet silent thought I summon up remembrance of things past,I sigh the lack of many a thing I sought,
|

# And with old woes new wail my dear time's waste:Then can I drown an eye, unus'd to flow,or precious friends hid in death's dateless night,
|
|
# And weep afresh love's long since cancell'd woe,And moan th' expense of many a vanish'd sight;Then can I grieve at grievances foregone,
|
|
# And heavily from woe to woe tell o'er The sad account of fore-bemoaned moan,Which I new pay as if not paid before.

# Late August, given heavy rain and sun For a full week, the blackberries would ripen.
|
|
# At first, just one, a glossy purple clot Among others, red, green, hard as a knot.
|
|
# You ate that first one and its flesh was sweetLike thickened wine: summer's blood was in it
|
|
# Leaving stains upon the tongue and lust for Picking. Then red ones inked up and that hunger
|
|
# Sent us out with milk cans, pea tins, jam-pots Where briars scratched and wet grass bleached our boots.
|
|
# Round hayfields, cornfields and potato-drills We trekked and picked until the cans were full,
|
|
# Until the tinkling bottom had been covered With green ones, and on top big dark blobs burned Like a plate of eyes.
|
|
# Our hands were peppered With thorn pricks, our palms sticky as Bluebeard's.
|
|
# We hoarded the fresh berries in the byre.But when the bath was filled we found a fur,A rat-grey fungus, glutting on our cache.
|
|
# The juice was stinking too. Once off the bush The fruit fermented, the sweet flesh would turn sour.
|
|
# I always felt like crying. It wasn't fair That all the lovely canfuls smelt of rot.
|

# Each year I hoped they'd keep, knew they would not. |
