Oz!--that marvelous country where no one grows old--where animals and birds talk as sensibly as people, and adventures happen every day. Indeed, of all fairylands in the world, Oz is the most delightful, and of all fairy cities, the Emerald City is the most beautiful. A soft green light shone for miles about, and the gemmed turrets and spires of the palace flashed more brightly than the stars. But its loveliness was familiar to Professor Wogglebug, and without a pause he proceeded to Ozma's palace and was at once admitted to the great hall. A roar of merriment greeted his ears. Ozma, the lovely girl ruler of Oz, was having a party, and the room was full of most surprising people--surprising to some, that is, but old friends to most of us. Jack, holding tightly to his pumpkin head, was running as fast as his wooden feet and wobbly legs would take him from Dorothy. A game of blind-man's-buff was in full swing, and Scraps and Tik-Tok, the Scarecrow and Nick Chopper, the Glass Cat and the Cowardly Lion, the Wizard of Oz and the wooden Sawhorse, Cap'n Bill and Betsy Bobbin, Billina and the Hungry Tiger were tumbling over each other in an effort to keep away from the blindfolded little girl.

"Where did you lose it?" asked Jack Pumpkinhead, edging forward anxiously. "Lose it! Who said I'd lost it?" snapped the Professor, glaring at poor Jack. "Well, you said you'd had it, and had is the past tense, so--" Jack's voice trailed off uncertainly, and Ozma, seeing he was embarrassed, begged the Professor to explain. "Your Highness!" began Professor Wogglebug, while the company settled down in a resigned circle on the floor, "As Oz is the most interesting and delightful country on the Continent of Imagination and its people the most unusual and talented, I am about to compile a Royal Book which will give the names and history of all our people. In other words, I am to be the Great, Grand Genealogist of Oz!" "Whatever that is," the Scarecrow whispered in Dorothy's ear. "And," the Professor frowned severely on the Scarecrow, "with your Majesty's permission, I shall start at once!" "Please do," said the Scarecrow with a wave toward the door, "and we will go on with the party!" Scraps, the Patchwork Girl, who had been staring fixedly at the Professor with her silver suspender-button eyes, now sprang to her feet:
