"Who is he?" she asked.

"He is the teacher of the school over the Ridge--what is known as the Ridge College," said the Doctor, with a smile.

"Alice, I thought the Doctor said you were not to talk."

The Doctor's face wore an amused expression.

"Well, just one more question," said the girl to him. "How much does a sack of salt weigh?"

"About two hundred pounds. To be accurate,--"

"No wonder he said I was light," laughed the girl.

"Who is a young man named Keith--a school-boy, who lives about here?" inquired Mrs. Yorke, suddenly.
