But this is more serious than the Barrier of Fire, because the only way to destroy the wall is to get on the other side of it." "How can that be done ?" asked Dorothy.
The Wizard looked thoughtfully around his little party, and his face grew troubled.

"It's a pretty high wall," he sadly remarked.

"I'm pretty sure the Cowardly Lion could not leap over it." "I'm sure of that, too!" said the Lion with a shudder of fear.

"If I foolishly tried such a leap, I would be caught on those dreadful spikes." "I think I could do it, sir," said the Frogman with a bow to the Wizard.

"It is an uphill jump as well as being a high jump, but I'm considered something of a jumper by my friends in the Yip Country, and I believe a good, strong leap will carry me to the other side." "I'm sure it would," agreed the Cookie Cook.
"Leaping, you know, is a froglike accomplishment," continued the Frogman modestly, "but please tell me what I am to do when I reach the other side of the wall." "You're a brave creature," said the Wizard admiringly.
