" Now then, Mr. Crab," said the zebra, "here are the people I told you about; and they know more than you do, who live in a pool, and more than I do, who live in a forest. For they have been travelers all over the world, and know every part of it."
"There's more of the world than Oz," declared the crab, in a stubborn voice.
"That is true," said Dorothy; "but I used to live in Kansas, in the United States, and I've been to California and to Australia--and so has Uncle Henry."
"For my part," added the Shaggy Man, "I've been to Mexico and Boston and many other foreign countries."
"And I," said the Wizard, "have been to Europe and Ireland."
"So you see," continued the zebra, addressing the crab, "here are people of real consequence, who know what they are talking about. "
