She dropped it on his arm and burst into tears, and he stroked her hair gently, as if she had been a little child and he a patient, loving father. She raised her face presently, smiling, though her lips still quivered.

"Do you really and truly wish me to go with—this afternoon?"

It seemed to him that for a full minute he could not speak, but in reality the pause was so brief that she did not notice it.

"Yes," he said quietly, "I really and truly do. It would not be fair to disappoint Mr. Symington, after making the engagement."

"And can't you possibly go, dear?" she asked entreatingly.

I think only one man was ever known to pull the cord which set in motion a guillotine that took off his own head. But there is much unknown, as well as unwritten, history.

"Not without neglecting some work which I ought to do to-day," he said.

"I think you care more for your work sometimes than you do for me." There was a little quaver in her voice as she spoke. "And I wish you'd stop behaving as if I were your daughter. I don't know what ails you this morning; but if you go on this way I shall call you Professor Silex all the time. How would you like that?"

A passionate exclamation rose to his lips, and died there. A spasm of bitter pain made his face for a moment hard and stern. Then he smiled, and said gently, "I should not like it at all, as you know very well. But I must go now, or I shall be late for my class. Good-by, dear child." And, parting her soft, curling hair, he pressed a fatherly kiss upon her forehead.

She threw her arms about his neck, crying, "No!—on my lips." And, pressing an eager kiss upon his mouth, she added, "There! that is a sealing, a fresh sealing, of our engagement; and I wish—oh, how I wish!—that we were to be married to-morrow—to-day!"
