I have read an edition containing three of the thirteen "contes d'une grand-mère" in French:
1. "Ce que disent les fleurs," interesting conversation between different flowers and the zephyr wind.
2. "La fée poussière," where George Sand exhibits a surprising knowledge of the science of her time, mixed with a subtle touch of the ideas of Pierre Leroux, which point towards a belief in reincarnation and an anticipation of Nietzsche's Superman.
3. "Le marteau rouge," interesting review of the story of a carnelian stone moved first by a glacier, then by the waters of a spring, converted into a war hammer by a man of the stone age, used as a kitchen knife, lost for centuries, re-discovered by an antiquarian, reduced by his widow to the state of a belt clasp, crumbled by a little girl to make soup for her doll, and finally reduced to a little ring stone, carefully preserved by another little girl.
