They watched the sky every day, to see if there were any signs of rain.
"I see a little cloud," said Bobby every few days. "Perhaps it will rain to-day."
But the little cloud would float lazily across the sky and bring no rain.
Every day the ducks would go in a procession down to the Duck Pond to swim. Every day they would find the Duck Pond dry and come back, one behind another, and take a drink from the tub of water at the pump.
And so five weeks passed.
At last, one day, big clouds gathered in the sky.
Bobby saw them first and came running in to tell the news.
"It's going to rain," he shouted. "See the big, big clouds."
Mother and Sue went to the door and looked out.
"It's surely going to rain," they said.
