At last the sun and the wind began to carry great pieces of the cloud blanket high into the sky. Through the openings in the clouds, below them the boys could see tiny villages and blue lakes.

And away down below, hanging in the soft white clouds, was a rainbow—all red and orange and yellow and green and blue and violet.

"Look! We are above the rainbow bridge!" cried Joe. "If only I could jump over on it, I could slide right down to the earth again."

"Why, you are on the earth now," said Jack.

"Oh, so I am! But isn't it wonderful up here!"

The boys watched the fluffy clouds blow far away, carrying the lovely rainbow with them. And they watched the great red sun drop down behind the snow-covered mountains in the west.

Suddenly Joe cried, "Those mountains are on fire, Jack! Look! How can they burn when they are all covered with snow?"

"It looks as if the red-hot sun had set the world on fire this time, doesn't it?" cried Jack.
