In her magnificent palace in the Emerald City, the beautiful girl Ruler of all the wonderful Land of Oz sat in her dainty boudoir with her friend Princess Dorothy beside her. Ozma was studying a roll of manuscript which she had taken from the Royal Library, while Dorothy worked at her embroidery and at times stooped to pat a shaggy little black dog that lay at her feet. The little dog's name was Toto, and he was Dorothy's faithful companion.  
To judge Ozma of Oz by the standards of our world, you would think her very young—perhaps fourteen or fifteen years of age—yet for years she had ruled the Land of Oz and had never seemed a bit older. Dorothy appeared much younger than Ozma. She had been a little girl when first she came to the Land of Oz, and she was a little girl still, and would never seem to be a day older while she lived in this wonderful fairyland.
 
Oz was not always a fairyland, I am told. Once it was much like other lands, except it was shut in by a dreadful desert of sandy wastes that lay all around it, thus preventing its people from all contact with the rest of the world. Seeing this isolation, the fairy band of Queen Lurline, passing over Oz while on a journey, enchanted the country and so made it a Fairyland. And Queen Lurline left one of her fairies to rule this enchanted Land of Oz, and then passed on and forgot all about it.
 
From that moment no one in Oz ever died. Those who were old remained old; those who were young and strong did not change as years passed them by; the children remained children always, and played and romped to their hearts' content, while all the babies lived in their cradles and were tenderly cared for and never grew up. So people in Oz stopped counting how old they were in years, for years made no difference in their appearance and could not alter their station. They did not get sick, so there were no doctors among them. Accidents might happen to some, on rare occasions, it is true, and while no one could die naturally, as other people do, it was possible that one might be totally destroyed. Such incidents, however, were very unusual, and so seldom was there anything to worry over that the Oz people were as happy and contented as can be.
 
Another strange thing about this fairy Land of Oz was that whoever managed to enter it from the outside world came under the magic spell of the place and did not change in appearance as long as they lived there. So Dorothy, who now lived with Ozma, seemed just the same sweet little girl she had been when first she came to this delightful fairyland.
 
Perhaps all parts of Oz might not be called truly delightful, but it was surely delightful in the neighborhood of the Emerald City, where Ozma reigned. Her loving influence was felt for many miles around, but there were places in the mountains of the Gillikin Country, and the forests of the Quadling Country, and perhaps in far-away parts of the Munchkin and Winkie Countries, where the inhabitants were somewhat rude and uncivilized and had not yet come under the spell of Ozma's wise and kindly rule. Also, when Oz first became a fairyland, it harbored several witches and magicians and sorcerers and necromancers, who were scattered in various parts, but most of these had been deprived of their magic powers, and Ozma had issued a royal edict forbidding anyone in her dominions to work magic except Glinda the Good and the Wizard of Oz. Ozma herself, being a real fairy, knew a lot of magic, but she only used it to benefit her subjects.
 
This little explanation will help you to understand better the story you are reaching, but most of it is already known to those who are familiar with the Oz people whose adventures they have followed in other Oz books.
 
Ozma and Dorothy were fast friends and were much together. Everyone in Oz loved Dorothy almost as well as they did their lovely Ruler, for the little Kansas girl's good fortune had not spoiled her or rendered her at all vain. She was just the same brave and true and adventurous child as before she lived in a royal palace and became the chum of the fairy Ozma.
 
In the room in which the two sat—which was one of Ozma's private suite of apartments—hung the famous Magic Picture. This was the source of constant interest to little Dorothy. One had but to stand before it and wish to see what any person was doing, and at once a scene would flash upon the magic canvas which showed exactly where that person was, and like our own moving pictures would reproduce the actions of that person as long as you cared to wat............
