The four travelers passed through the rest of the forest in safety, and when they came out from its gloom saw before them a steep hill, covered from top to bottom with great pieces of rock.

“That will be a hard climb,” said the Scarecrow, “but we must get over the hill, nevertheless.”

So he led the way and the others followed. They had nearly reached the first rock when they heard a rough voice cry out, “Keep back!”

“Who are you?” asked the Scarecrow.

Then a head showed itself over the rock and the same voice said, “This hill belongs to us, and we don't allow anyone to cross it.”

“But we must cross it,” said the Scarecrow.
