“ Isn't it queer?"
"It's queer that buttons can see at all," answered Trot; "but—good gracious! What's become of the city?"
"I was going to ask that myself," said Dorothy. "It's gone!"
"It's gone!"
The animals came to a sudden halt, for the city had really disappeared, walls and all, and before them lay the clear, unbroken sweep of the country.
"Dear me!" exclaimed the Wizard. "This is rather disagreeable. It is annoying to travel almost to a place and then find it is not there."

“ And don't you want to find her?" asked Betsy reproachfully.
"Yes indeed," said Scraps, walking on her hands as an acrobat does at the circus.
"Well, we can't find Ozma unless we get past these thistles," declared Dorothy.
Scraps danced around them two or three times without reply. Then she said:
"Don't look at me, you stupid folks. Look at those blankets."
The Wizard's face brightened at once.
"Why didn't we think of those blankets before?"
"Because you haven't magic brains," laughed Scraps. "Such brains as you have are of the common sort that grow in your heads, like weeds in a garden. ”

"It's mighty queer, isn't it?" asked Button-Bright.
"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." ”
