"Considering that the sun will not stay to be talked about, Daisy," said the doctor glancing out of the window, "I should say it would."

"Then I will ask only one thing more. Dr. Sandford, how can you tell so exactly how long it would take to go to the sun? how do you know?"

"Quite fair, Daisy," said the doctor surveying her gravely. "I know, by the power of a science called mathematics, which enables one to do all sorts of impossible things. But you must take that on my word; I cannot explain so that you would understand it."

"Thank you, sir," said Daisy.

She wanted further to ask what sort of a science mathematics might be; but Dr. Sandford had answered a good many questions, and the sun was down, down, behind the trees on the other side of the road. Daisy said no more. The doctor seeing her silent, smiled, and prepared himself to go.

"Shall we finish the sun to-morrow, Daisy?"

"O, if you please."

"Very well. Good bye."

The doctor went, leaving Daisy in a very refreshed state; with plenty to think of. Daisy was quite waked out of her weariness and disappointment, and could do well enough without books for one day longer. She took her own raspberries now with great spirit.

"I have found two more wonderful things to talk to Dr. Sandford about,
Juanita; that is three to-day."
