Aword sticks in the wind’s throat; a wind-launch drifts in the swells of rye; sometimes, in broad silence, the hanging apples distil their darkness. you, in a green dress, calling, and with brown hair, who come by the field-path now, whose name i say softly, forgive me love if also i call you wind's word, apple-heart, haven of grasses.
