• From the borders of the paths ascended tall grasses, as in the month of May, and large, umbellated flowers, mistaken about the season; in the hedges, privets and briars had come into bloom again, in the buzz of the last bees; and one could see flying persistent butterflies, to whom death had given several weeks of grace. Pierre Loti in "Ramuntcho".
