"Well," said Uncle Robert, "can you find out how many inches there are in all?"
It took some time and several suggestions from Uncle Robert, but at last they found it to be two hundred thirty-one cubic inches.
"Now," said Uncle Robert, "can you find how many two hundred thirty-one cubic inches there are in two hundred and sixteen thousand cubic inches?"
"I know how," said Frank, figuring rapidly.
In a short time he found that two hundred and sixteen thousand cubic inches would make over nine hundred thirty-five gallons.
"If you were going to water the garden with the new two-gallon pail," said Uncle Robert, "how many times would you have to fill it?"
"If we took two gallons at a time," said Frank, "it would be—wait a minute—it would be four hundred sixty-seven and one half."
"My," said Donald, "it makes my arms ache to think of it."
"I'm going to find out how much fell on the whole farm some time," said
Frank, "but I'm just tired out now."
"Where does all the rain come from?" asked Susie. "I don't see how so much water can stay in the clouds."
