"Yes," said Clifford.

"She is not fond of chemistry, I think."

"No."

"Nor is she botanical."

"No," said Clifford.

"Nevertheless, she has a great charm," said Gerda. "Tante calls it temperamental charm. It must be delightful to have that mysterious gift. For it is a gift, and it is mysterious."

Clifford was silent. Gerda thought he was not interested in the Englishwoman.

"How blind he is!" she thought. "Even my Ejnar uses his eyes better. He knows that woman is charming."

Katharine was indeed charming that morning, and to every one. She had put little Fröken Eriksen, the Swedish artist, and the Swedish mathematical Professor, Herr Lindstedt, into the gig, so that they might enjoy a comfortable flirtation together. They laughed and greeted her pleasantly as they drove on in front.

"Tack!" they said, turning round and waving to her. They felt she understood so well.
