L. Frank Baum,
The Emerald City of Oz — Chapter 30…
(1910)
“ Still, we have no right to feel grieved, for we have had enough of the history of the Land of Oz to fill six story books, and from its quaint people and their strange adventures we have been able to learn many useful and amusing things.So good luck to little Dorothy and her companions. May they live long in their invisible country and be very happy! ”
