the effects of a sweet nature
"You are so very pretty, my dear, so good and so mannerly, that I cannot help giving you a gift." For this was a fairy, who had taken the form of a poor country woman, to see how far the civility and good manners of this pretty girl would go. "I will give you for a gift," continued the Fairy, "that, at every word you speak, there shall come out of your mouth either a flower or a jewel."
