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. # secret3 # 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. # But if the while I think on thee, dear friend,All losses are restor'd, and sorrows end. # secret4 # 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.
