"I beg your pardon, mother," he answered: "I must think about it. Why should it trouble you so! It is painfully annoying, but we have come under no obligation to them!"

"No; but Alister!"

"You cannot doubt Alister will do what is right!"

"He will do what he thinks right!"

"Is not that enough, mother?"

"No," she answered angrily; "he must do the thing that is right."

"Whether he knows it or not? Could he do the thing he thought wrong?"

She was silent.
