"Yes," agreed the Wizard, "it seems odd that a little match could
destroy such a great circle of fire, but when Glinda invented this trick
she believed no one would ever think of a match being a remedy for fire.
I suppose even Ugu doesn't know how we managed to quench the flames of
his barrier, for only Glinda and I know the secret. Glinda's Book of
Magic, which Ugu stole, told how to make the flames, but not how to put
them out."

They now formed in marching order and proceeded to advance up the slope
of the hill; but had not gone far when before them rose a wall of steel,
the surface of which was thickly covered with sharp, gleaming points
resembling daggers. The wall completely surrounded the wicker castle
and its sharp points prevented anyone from climbing it. Even the
Patchwork Girl might be ripped to pieces if she dared attempt it.

"Ah!" exclaimed the Wizard cheerfully, "Ugu is now using one of my own
tricks against me. 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 up-hill 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. "Has anyone a
pin?"

Betsy had one, which she gave him.

"All you need do," said the Wizard to the Frogman, giving him the pin,
"is to stick this into the other side of the wall."

"But the wall is of steel!" exclaimed the big frog.

"I know; at least, it _seems_ to be steel; but do as I tell you. Stick
the pin into the wall and it will disappear."

The Frogman took off his handsome coat and carefully folded it and laid
it
