"Plenty of room, and to spare."

Daisy was silent now. Preston looked from her face to the doctor's.

"Not only that, Daisy; but the moon then would be two hundred thousand miles within the circumference of the sun; the sun's surface would be two hundred thousand miles beyond her."

"Thank you, Dr. Sandford!"

"What for, Daisy?"

"I am so glad to know all that."

"Why?"

Daisy did not answer. She did not feel ready to tell her whole thought, not to both her friends together, at least; and she did not know how to frame her reply. But then, perceiving that Dr. Sandford was looking for an answer, and that she was guilty of the rudeness of withholding it, she blushed and spoke.

"It makes me understand some things better."

"What, for instance?" said the doctor, looking as grave as ever, though Preston was inclined to laugh.
