then she recited , almost into my shoulder , quite effortlessly , one of yeats most beautiful poems : had i the heavens embroidered cloths , enwrought with golden and silver light , the blue and the dim and the dark cloths of night and light and the half-light , i would spread the cloths under your feet but i , being poor , have only my dreams , i have spread my dreams under your feet , tread softly because you tread on my dreams .
