"Where does this water come from?" asked Uncle Robert.
"From out of the ground," said Susie. "How does it get into the ground?"
[Illustration: The spring.]
"It's always there, isn't it?" said Susie. "The spring runs all the time. I fill my pail here every day in the summer."
"Yes, don't you remember when the wells all dried up last summer," said
Frank, "that the spring was all right?"
"Well, then, where has the water gone that fell to-day?" asked Uncle
Robert.
"Most of it has run off into the creek and river," said Donald. "It would look just like a lake if it was an inch and a half deep all over the ground."
"Some of it has soaked into the ground," said Frank.
"How deep down into the ground?" asked Uncle Robert.
"Down to China," laughed Donald.
