Once upon a time in a certain country there lived a king whose palace was surrounded by a spacious garden. But, though the gardeners were many and the soil was good, this garden yielded neither flowers nor fruits, not even grass or shady trees. The King was in despair about it, when a wise old man said to him: "Your gardeners do not understand their business: but what can you expect of men whose fathers were cobblers and carpenters? How should they have learned to cultivate your garden?" "You are quite right," cried the King. "Therefore," continued the old man, "you should send for a gardener whose father and grandfather have been gardeners before him, and very soon your garden will be full of green grass and gay flowers, and you will enjoy its delicious fruit."
