"Not a real baby," said she. "We both act like children at times—very little children. But we'd not care for each other as we do if either of us were really infantile. It takes a grown person to play baby attractively."

"Baby," he insisted fondly. He was smiling with the masculinely patronizing tolerance to which she had grown so used that she never noted it. He appreciated that she was clever—with the woman sort of cleverness—bright, witty, sometimes saying remarkably keen things. But, being a man, he knew that man mind and woman mind are entirely different—never so different as when woman mind seems to be like man mind—just as purely instinctive actions of animals seem to display profound reasoning power. "And what was the baby wrinkling its brow over, in there? The care and feeding of infants?"

"Dear me, no," replied she with perfect good humor. "I went into that before Winchie came. You think it's all a joke—my reading and studying. But the real joke is your thinking so. You must remember I can't afford to let myself go, as you do."

"You've given up everything for chemistry. Haven't you noticed that we can hardly talk to each other—that you can hardly talk to anybody?"

"I never did have much talent for small talk."

"But I didn't mean small talk. You care only for chemistry, know only chemistry. You never did know or care much about literature or art or music or any of the worth-while things except just your own specialty. And you can afford to be that way. It's your career, and also you're not a woman and a mother."

"A man can afford to be narrow—not to know life or the world. But a mother—if she's the right sort—has to try to know everything. She's got to bring up children—and how can she hope to teach and train successfully if she doesn't know?"

"I don't agree with you," said he, a certain curtness in his voice. "A woman must be pure, innocent, womanly—as you are. Nature didn't make her to be learned or wise—to think. She has her instincts to keep her straight, and a father or a husband——"
