Dorothy and her friends were worried to get out of the forest as soon as they could, so they hurried along the yellow brick road. It was not long before they came to a wide river.

"What can we do now?" Dorothy exclaimed. "There isn't a tree tall enough to fall across this river. "

"There's no problem, "the Scarecrow (稻草人)said. "The Tin Woodman will use his axe to build a raft (木筏) . "

And this is what the Tin Woodman did. And while he was busy making the raft, Dorothy found some wild fruit and nuts, which she ate hungrily. Then, because it was taking the Tin Woodman a long time to finish the raft, Dorothy lay down and went t sleep.

The night passed without any problems, and the next morning the raft was ready. Dorothy sat in the middle with Toto. The Lion stood at one end and nearly sank (下沉)it because he was so big and heavy. The Scarecrow and the Tin Woodman stood at the other end They both had long poles (杆子)that they used to push the raft through the water.

At first all went well, but then the river became so deep that the poles could not touch the bottom.

The Tin Woodman said, "If we cannot stay near the land and the yellow brick road, the Wicked Witch of the West will use her magic and put a spell (咒语)on us. "

"And then we won't meet the Wizard, and I won't get any brains, " the Scarecrow said.

"And I won't get a heart, "the Tin Woodman said.

"And I won't get any courage, "the Lion said.

"And I'll never get home to Kansas, " Dorothy said. "we must do something"

The Scarecrow was able to push the raft to the river bank. Dorothy, Toto, the Lion and the Tin

Woodman got off. Before the Scarecrow could get off however, the raft moved away from the river band and carried the Scarecrow down the river.

Dorothy said, "Perhaps we'll met the raft further down the river. The most important thing now is to get back to the yellow brick road and continue on our way to the City of Emeralds. "

The Lion and the Tin Woodman agreed, and they set off along the river bank. It was not long before they saw the Scarecrow. He was holding onto the pole in the middle of the river. There was no sight of the raft.
