Her friend meanwhile had been recovering his mental equilibrium. He assumed his little air of pedantic dignity, feeling that he had got the best of the argument.

"I don't think you and I altogether understand one another," he said. "I have made a deep study of the problems of life, and so see things rather differently from you. I call a spade a spade, and am not taken in by the so-called illusions of youth. I know what men are, and should advise you to be a little more careful in what you do and say."

"What on earth do you mean?" Lilly asked in astonishment.

He smiled with a half-embarrassed and half-superior air as he glanced askance at her.

"Well, you know, beauty has certain dangers connected with it."

"Beauty!" Lilly cried, burning all over. "What nonsense!"

"Those on whom nature has conferred this gift have special reasons to be more cautious than others less favoured. For instance, it is lucky for you that you have fallen in with anyone so correct, old-fashioned, and honourable in his ideas as I am. Another, less steady, more frivolously inclined, might easily, you know, have taken advantage of such a walk as this. You may indeed be quite sure that he would."

Lilly stared at him in dismay. She was overwhelmed in a whirl of far from agreeable reflections. What did he want her to do? Was he reproaching her, or making fun of her most sacred sentiments?

"Oh, good heavens!" she exclaimed, completely losing her composure. "I wish we were at home."

"You mustn't misunderstand me, Fräulein," he began again. "I am not a saint. I am fully acquainted with the weaknesses and failings of human nature. I am only offering you a word of counsel, for which you will one day be grateful to me. Principles count for something, and in after-life, if we meet again, you will, it is to be hoped, have no reason to be ashamed of the acquaintance made in your youth."
