The professor regarded this outspoken young man with an air of hurt dignity.

“If you will forgive me,” he said. “I think that we will choose another subject of conversation.”

“At any rate,” Tavernake declared, “you must be fond of your daughter or you would not come here night after night just to look at her.”

The professor shook out a handkerchief from his pocket and dabbed his eyes.

“Beatrice was always my favorite,” he announced solemnly, “but Elizabeth—well, you can't get away from Elizabeth,” he added, leaning across the table. “To tell you the truth, Mr. Tavernake, Elizabeth terrifies me sometimes, she is so bold. I am afraid where her scheming may land us. I would be happier with Beatrice if only she had the means to satisfy my trifling wants.”

He turned to the waiter and ordered a pint of champagne.

“Veuve Clicquot '99,” he instructed the man. “At my age,” he remarked, with a sigh, “one has to be careful about these little matters. The wrong brand of champagne means a sleepless night.”

“If I could tell you of that girl's mother, Mr. Tavernake,” he said, “if I could tell you what her history, our history, has been, it would seem to you so strange that you would probably regard me as a romancer. No, we have to carry our secrets with us.”

“By-the-bye,” Tavernake asked, “what are you a professor of?”
