"O I should like to see the spots on the sun!" said Daisy. "You said they were holes in the curtain, sir?"
"Yes."
"What curtain?" said Preston.
"You are not a philosopher," said the doctor.
"How long does it take them, the spots, Dr. Sandford, to go round and come back again?"
"A little more than twenty-five days."
"How very curious!" said Daisy. "I wonder what it turns round for—the sun, I mean?"
"You have got too deep there," said the doctor. "I cannot tell you."
"But there must be some reason," said Daisy; "or it would stand still."
"It is in the nature of the thing, I suppose," said Dr. Sandford; "but we do not fully know its nature yet. Only what I am telling you."
