"I must rush to her defence. She did not know until the end of the evening who I was. She took me for one of the several Easterners who arrived to-day. Two of them brought letters to her father from Mr. Forbes. One was the son of an old friend. As her father presented me—"

Magdaléna faced about. "And you did not tell her? You did not speak of me?"

"I am going to be perfectly frank, knowing how sensible you are. I had a desperate flirtation with your friend, as desperate and meaningless as those things always are; for it is merely an invention to pass the idler hours of society. There was nothing else to do, so we flirted. It added to the zest to keep her in ignorance of my identity. It was a silly pastime, but better than nothing. I should far rather have been in bed. If I could have talked to you, it would have been quite another matter."

Magdaléna hurried on ahead. He had the tact not to accelerate his own steps. After a time she fell back. She said,—

"What is this 'flirtation,' anyhow? I have heard nothing but 'flirtation' all winter, and I heard a good deal of it last summer. But I have not the slightest idea what it means. What do you do?"

"Do? Oh—I—it is impossible to define flirtation. You must have the instinct to understand. Then you wouldn't ask. Thank Heaven you never will understand. Flirtation is to love-making what soda-water is to champagne. I can think of no better definition than that."

"Did you kiss Helena?"

"Good God, no! That's not flirtation. She is not the sort that would let me if I wished."

"Did you hold her hand?"

"I have held no woman's hand but yours for an incalculable time."
