"And then it rises up from the ocean and comes back again in clouds."
"Did those clouds we had this morning come all the way from the ocean?" asked Joe. "I don't see how they could come so far?"
"The clouds have swift wings to carry them," replied Uncle Robert. "They travel very far without tiring."
"The wind brings the clouds, doesn't it, uncle?" asked Susie.
"Yes, they come on the wings of the wind."
"Oh," said Joe, "I see."
"There's father blowing the horn," said Dick. "We must go."
"Come again," said Uncle Robert and the children together.
"I wish we could hear more about the river," said Joe to Frank as he helped them push off the boat.
"Come over again any day," said Frank. "Uncle Robert will tell you all about it."
