"Well—here's the—the 'prentice," said Dick. "You're not busy nowadays. Take charge of her."

"It'll be a great pleasure, I'm sure," he stammered. He looked about as uncomfortable at sight of her as had Richard. Demurely she followed him into his compartment. As the partition did not extend to the ceiling, they had to content themselves with an exchange of eloquent glances. Then, taking the tone of gentleman chemist to not overbright and densely ignorant lady visitor at a laboratory, he began to explain to her the names and uses of things, and to demonstrate how to use them.

For the entire morning he talked and illustrated, thoroughly enjoying himself at making a fine impression with his display of superior knowledge. He told her little she did not already know. But she was not so tactless as to spoil his pleasure or hurt his vanity. She listened and tried; and when he complimented her on her quickness in learning, she showed delight at being praised. In the afternoon he allowed her to practice his teachings unassisted—set her at weighing a little nitrate of potassium precipitate in the gold and ivory and aluminum balances. She had done this sort of things a hundred times, but was meek under his elaborations of cautioning and explaining.

"I worked a lot in laboratories at school," said she ingenuously, when his guidance became a little tiresome. "It's beginning to come back to me."

He smiled in a way that reminded her of Richard. "All right. Do the best you can," said he. "We'll not expect much of you for the present. I'm afraid you'll soon give up."

She looked at him. "I'm here to stay," said she, "You'll not get rid of me."

"But the work's very hard—not at all feminine."

"That suits me. For, I'm not at all feminine, myself—what men mean by feminine."

He laughed, went about his own business. As she sat at the balances, her whole mind on the needle she was watching through the reading glass, she felt herself caught from behind. She turned her laughing face upward and backward, and they kissed. "Isn't it splendid!" he exclaimed under his breath. "Yes—you must stay." It had been part of her plan of life that they should never caress. Suddenly she realized how impossible this rule was—and how foolish. On occasions—such occasions as this joy in the unexpected kindness of fate—the rule must be suspended.

"How long it's been!" he said in a low voice. "Not since early September have I kissed you—and this is almost February."
