The Giant Horse of Oz by Ruth Plumly Thompson

Far to the North, walled in on all sides by the craggy slopes of the / Munchkin Mountains, lies the great Lost Lake of Orizon. And glittering / on its blue bosom, like a large and lovely necklace, rest the Ozure / Isles of Oz. Now Oz itself, this mysterious land about which we read / and hear so often, is a large oblong Kingdom divided into four smaller / Kingdoms with the Emerald City in the exact center. Here dwells Ozma, / the present ruler, a little fairy of great gentleness and power. While / all the Kingdoms in Oz are subject to Ozma, each has its own special / sovereign.

For instance, the Northern Country of the Gillikens is governed by the / Good Witch Tattypoo; The Red Land of the Quadlings, by Glinda the Good / Sorceress of the South; the Western and Yellow Empire of the Winkies is / under the kindly control of Nick Chopper, the Tin Woodman of Oz; the / blue Munchkin Country is governed by a King of whom nothing much has / been heard for many a long year. But be that as it may, it is in the / Munchkin Country that the great Lost Lake of Orizon lies.
