“Well?” said Billy, as Nimbus paused.

“Well,” repeated the Fairy, “don’t you see? Their tears were rain!”

“Oh!” said Billy.

“The next thing that happened was that their mothers looked up from their sewing and saw the dark spot over the park, where, a few minutes ago, it had all been bright and sunny. They knew what had happened, for in April and May the Cloud children are easily upset and cry if you poke your finger at them. So they floated over to the park and, instead of asking the children what the matter was, as most mothers would have done, Mrs. Gold-Cloud told the children to look down at the park.”

“And what did they see?” asked Billy, who never before had thought of looking at the Earth children through the eyes of the clouds.

“Why, the rain spoiling all the pretty white dresses and the children all stopping their play and rushing about for shelter.”

“I know,” said Billy. “I was there myself.”

“Were you?” said Nimbus. “Then you know what happened.”

“I only know it stopped raining,” said Billy.

“But don’t you know why?” asked Nimbus.
