Harriet nestled closer.

"But I want to help now. I'm afraid I've been thoughtless and selfish. You look so miserable to-night. It cuts me to the heart."

"Nonsense, Baby dear," he broke in cheerfully. "I'm not miserable. I've really had a good day. I've spent the whole afternoon superintending the distributing of flowers among the hospitals. And I've discovered a curious thing—you couldn't imagine what it is?"

The doctor paused and laughed in his old playful way.

"What?" she cried.

Harriet clapped her hands with a moment's childish happiness as she had done so often when her father propounded one of his mysterious problems for her solution.

The doctor whispered:

"I've discovered that pinks are feminine and roses masculine."

"How?"

"Because the men in the hospitals all beg for pinks and the women for roses. It's curious. I never hit on the explanation before. Isn't it reasonable?"
