"Well now, isn't she a fool!" shouted the prince, pushing the book aside and turning sharply away; but rising immediately, he paced up and down, lightly touched his daughter's hair and sat down again.

"This won't do, Princess; it won't do," said he, when Princess Mary, having taken and closed the exercise book with the next day's lesson, was about to leave: "Mathematics are most important, madam! I don't want to have you like our silly ladies.

Get used to it and you'll like it," and he patted her cheek.
