Then she looked to the north, and saw a deep but narrow valley lying between two rocky mountains, and a third mountain that shut off the valley at the further end. Westward the fertile Land of Ev suddenly ended a little way from the palace, and the girl could see miles and miles of sandy desert that stretched farther than her eyes could reach. It was this desert, she thought, with much interest, that alone separated her from the wonderful Land of Oz, and she remembered sorrowfully that she had been told no one had ever been able to cross this dangerous waste but herself. Once a cyclone had carried her across it, and a magical pair of silver shoes had carried her back again. But now she had neither a cyclone nor silver shoes to assist her, and her condition was sad indeed. For she had become the prisoner of a disagreeable princess who insisted that she must exchange her head for another one that she was not used to, and which might not fit her at all. Really, there seemed no hope of help for her from her old friends in the Land of Oz. Thoughtfully she gazed from her narrow window. On all the desert not a living thing was stirring. Wait, though! Something surely _was_ stirring on the desert--something her eyes had not observed at first. Now it seemed like a cloud; now it seemed like a spot of silver; now it seemed to be a mass of rainbow colors that moved swiftly toward her. What _could_ it be, she wondered? Then, gradually, but in a brief space of time nevertheless, the vision drew near enough to Dorothy to make out what it was. A broad green carpet was unrolling itself upon the desert, while advancing across the carpet was a wonderful procession that made the girl open her eyes in amazement as she gazed. First came a magnificent golden chariot, drawn by a great Lion and an immense Tiger, who stood shoulder to shoulder and trotted along as gracefully as a well-matched team of thoroughbred horses. And standing upright within the chariot was a beautiful girl clothed in flowing robes of silver gauze and wearing a jeweled diadem upon her dainty head. She held in one hand the satin ribbons that guided her astonishing team, and in the other an ivory wand that separated at the top into two prongs, the prongs being tipped by the letters "O" and "Z", made of glistening diamonds set closely together. The girl seemed neither older nor larger than Dorothy herself, and at once the prisoner in the tower guessed, that the lovely driver of the chariot must be that Ozma of Oz of whom she had so lately heard from Tiktok. Following close behind the chariot Dorothy saw her old friend the Scarecrow, riding calmly astride a wooden Saw-Horse, which pranced and trotted as naturally as any meat horse could have done.
