"How can water go tumbling?" cried Jill. "We tumbled."

"Water tumbles too," replied the voice, "especially when it is frozen."

"Oh!" said Jack.

"Oh!" said Jill.

"The stream is frozen," called the voice.

"What stream?" asked the children together.

"The stream that goes down the hill," answered the voice. "Did you not know that you were bringing water to keep the stream full?"

"No, indeed," said the children.

"The old man of the hill is only a rock, and what you thought his voice was only the water flowing around it."
