"Impossible!" protested the zebra. "Why, I can run for days upon the land, and find but little water."
"Did you ever see an ocean?" asked Dorothy.
"Never," admitted the zebra. "There is no such thing as an ocean in the Land of Oz."
"Well, there are several oceans in the world," said Dorothy, "and people sail in ships upon these oceans for weeks and weeks, and never see a bit of land at all. And the joggerfys will tell you that all the oceans put together are bigger than all the land put together."
At this the crab began laughing in queer chuckles that reminded Dorothy of the way Billina sometimes cackled.
"Now will you give up, Mr. Zebra?" it cried, jeeringly; "now will you give up?"
The zebra seemed much humbled.
"Of course I cannot read geographys," he said.
"You could take one of the Wizard's School Pills," suggested Billina, "and that would make you learned and wise without studying."
The crab began laughing again, which so provoked the zebra that he tried to shake the little creature off. This resulted in more ear-pinching, and finally Dorothy told them that if they could not behave they must go back to the forest.
