As you are a stranger, I will explain this Law which to you seems so foolish.

Years ago there were many Witches and Magicians in the Land of Oz, and one of the things they often used in making their magic charms and transformations was a six-leaved clover.
These Witches and Magicians caused so much trouble among my people, often using their powers for evil rather than good, that I decided to forbid anyone to practice magic or sorcery except Glinda the Good and her assistant, the Wizard of Oz, both of whom I can trust to use their arts only to benefit my people and to make them happier.

Since I issued that Law the Land of Oz has been far more peaceful and quiet; but I learned that some of the Witches and Magicians were still practicing magic on the sly and using the six-leaved clovers to make their potions and charms.

Therefore I made another Law forbidding anyone from plucking a six-leaved clover or from gathering other plants and herbs which the Witches boil in their kettles to work magic with.

That has almost put an end to wicked sorcery in our land, so you see the Law was not a foolish one, but wise and just; and, in any event, it is wrong to disobey a Law." Ojo knew she was right and felt greatly mortified to realize he had acted and spoken so ridiculously.
