I study the lives on a leaf: the little Sleepers, numb nudgers in cold dimensions, Beetles in caves, newts, stone-deaf fishes, Lice tethered to long limp subterranean weeds, Squirmers in bogs, And bacterial creepers Wriggling through wounds Like elvers in ponds, Their wan mouths kissing the warm sutures, Cleaning and caressing, Creeping and healing. Theodore Roethke
