The Dainty China Country.
While the Woodman was making a ladder from wood which he found in the forest Dorothy lay down and slept, for she was tired by the long walk.
The Lion also curled himself up to sleep and Toto lay beside him.
The Scarecrow watched the Woodman while he worked, and said to him: "I cannot think why this wall is here, nor what it is made of." "Rest your brains and do not worry about the wall," replied the Woodman.

"When we have climbed over it, we shall know what is on the other side." After a time the ladder was finished.

It looked clumsy, but the Tin Woodman was sure it was strong and would answer their purpose.

The Scarecrow waked Dorothy and the Lion and Toto, and told them that the ladder was ready.
