Kansas was because her uncle and aunt loved her and needed her with them.

Now, however, all was to be changed, and Dorothy was really more
delighted to know that her dear relatives were to share in her good
fortune and enjoy the delights of the Land of Oz, than she was to
possess such luxury for herself.

Next morning, at Ozma's request, Dorothy dressed herself in a pretty
sky-blue gown of rich silk, trimmed with real pearls. The buckles of
her shoes were set with pearls, too, and more of these priceless gems
were on a lovely coronet which she wore upon her forehead. "For,"
said her friend Ozma, "from this time forth, my dear, you must assume
your rightful rank as a Princess of Oz, and being my chosen companion
you must dress in a way befitting the dignity of your position."

Dorothy agreed to this, although she knew that neither gowns nor
jewels could make her anything else than the simple, unaffected little
girl she had always been.

As soon as they had breakfasted--the girls eating together in Ozma's
pretty boudoir--the Ruler of Oz said:

"Now, dear friend, we will use the Magic Belt to transport your uncle
and aunt from Kansas to the Emerald City. But I think it would be
fitting, in receiving such distinguished guests, for us to sit in my
Throne Room."

"Oh, they're not very 'stinguished, Ozma," said Dorothy. "They're
just plain people, like me."
