"You are doing no outside work, Miss Fielding?" inquired the principal.

"No, Ma'am."

"I hear you are helping two of the other girls—in a perfectly legitimate way, of course. It is not taking too much out of you?"

"Oh, no, dear Mrs. Tellingham!" cried Ruth, fearful that her tutoring would be forbidden.

"You are not working too hard in the gym.?"

"I do not think so," stammered Ruth.

"And this is ridiculous," said Mrs. Tellingham, with a smile. "I do not think there is a more robust looking girl in my school. But, there must be something."

"I suppose so," murmured Ruth.

"But you do not know what it is? If you do, tell me."

"I study just as hard, Mrs. Tellingham," said Ruth, non-committally. "I spend quite as much thought over my books. Really, I think I shall do better again."
