“The rain,” replied Jonas.
“The rain?” said Rollo; “how?”
“Why, the rain,” replied Jonas, “is water coming down out of the air; and the bubbles are air coming up out of the water.”
“Then it is exactly the opposite of it,” said Rollo.
“Yes,” said Jonas.
“But you said it was like it.”
“Well, and so it is,” Jonas replied.
“Like it, and yet exactly opposite to it! Jonas, that is impossible.”
“Why, yes,” said Jonas, “the air gets down into the water, and you wonder how it can, when it is so much lighter than water. So water gets up into the air, and I wonder how it can, when it is so much heavier. So that the difficulty is just about the same.”
