"Oh, just in a figurative way, of course." The Wizard shrugged his shoulders. "You will observe," he went on enthusiastically, "that these planes need no runway or special track to take off. They really are balloonaplanes. Note those round packets on the top of the fusilage." The lion blinked rapidly, for he had no idea that fusilage meant the body of the plane, but the others nodded quite knowingly. "Well those," declared the inventor proudly "are my own, patented, balloon attachments. At the touch of a button, the wings are depressed and the balloon inflated with a magic gas, lighter than helium, that carries the ship as high and as far as desired. Then the balloon can be deflated and the Ozoplane can continue under its own power. But you will readily see how my ship, with its balloon attachment, has twice the altitude possibilities of an ordinary airplane. Hah! We shall fly _higher_ than higher!" boasted the little Wizard, happily. "Oh, quite!" agreed the Tin Woodman, mounting the ladder of the Oztober, the Soldier with Green Whiskers pressing nervously at his heels. "But how will you move them out of here?" inquired the Scarecrow, taking off his hat and scratching his cotton head. "Oh, as to that--" The Wizard pulled a switch just behind him, whereupon the top of the glass airdrome lifted, like the lid of an enormous jewel box. "Hmmmmn! I see!" The Scarecrow slapped his knee and grinned with appreciation. "Off with the roof! Up with the planes!" "Exactly!" Seizing the Straw Man's arm, the Wizard urged him toward the ladder of the Ozpril, Dorothy skipping cheerfully behind them. After Dorothy plodded the Cowardly Lion, talking to himself in anxious whispers and growls. "Be sure not to touch anything over there," called the Wizard, as Nick and the Soldier with Green Whiskers disappeared into the cabin of the other plane. "I'll keep an eye on them," promised Jellia, tripping up the ladder as lightly as a feather. "Don't give us a thought, Wiz, dear." "Jellia's so funny!" laughed Dorothy. "Sensible, too," added the Wizard, helping the little girl over the high door sill and into the plane. While he and the Scarecrow went forward to examine the steering gear, Dorothy looked delightedly 'round the snug little cabin. There were four seats upholstered in pale, green leather, along one side. The whole top was of thick glass, through which she could distinctly see the moon and stars winking down at her. The side walls of the Ozpril were of a silvery grey, with all trimmings in green. At the back was a small dinette, with chairs and table locked to the floors as they are on sea-going vessels. A cabinet full of china, a wall full of charts, a book case full of books and a tiny kitchen and dressing room, completed the equipment.
