"There must be some way for the people to get out and in," declared Dorothy. "Do you s'pose they have flying machines, Wizard?"
"No," he replied, "for in that case they would be flying all over the Land of Oz, and we know they have not done that. Flying machines are unknown here. I think it more likely that the people use ladders to get over the walls."
"It would be an awful climb, over that high stone wall," said Betsy.
"Stone, is it?" cried Scraps, who was again dancing wildly around, for she never tired and could never keep still for long.
"Course it's stone," answered Betsy scornfully. "Can't you see?"
"Yes," said Scraps, going closer, "I can see the wall, but I can't feel it." And then, with her arms outstretched, she did a very queer thing. She walked right into the wall and disappeared.
"For goodness sake!" cried Dorothy amazed, as indeed they all were.
