"The diamond mines?" broke out Lavinia. "Nasty, little spoiled thing, I should like to SLAP her!"

Sara got up quickly on her feet. It must be remembered that she had been very deeply absorbed in the book about the Bastille, and she had had to recall several things rapidly when she realized that she must go and take care of her adopted child. She was not an angel, and she was not fond of Lavinia.

"Well," she said, with some fire, "I should like to slap YOU—but I don't want to slap you!" restraining herself. "At least I both want to slap you—and I should LIKE to slap you—but I WON'T slap you. We are not little gutter children. We are both old enough to know better."

Here was Lavinia's opportunity.

"Ah, yes, your royal highness," she said. "We are princesses, I believe. At least one of us is. The school ought to be very fashionable now Miss Minchin has a princess for a pupil."

Sara started toward her. She looked as if she were going to box her ears. Perhaps she was. Her trick of pretending things was the joy of her life. She never spoke of it to girls she was not fond of. Her new "pretend" about being a princess was very near to her heart, and she was shy and sensitive about it. She had meant it to be rather a secret, and here was Lavinia deriding it before nearly all the school. She felt the blood rush up into her face and tingle in her ears. She only just saved herself. If you were a princess, you did not fly into rages. Her hand dropped, and she stood quite still a moment. When she spoke it was in a quiet, steady voice; she held her head up, and everybody listened to her.

"It's true," she said. "Sometimes I do pretend I am a princess. I pretend I am a princess, so that I can try and behave like one."

Lavinia could not think of exactly the right thing to say. Several times she had found that she could not think of a satisfactory reply when she was dealing with Sara. The reason for this was that, somehow, the rest always seemed to be vaguely in sympathy with her opponent. She saw now that they were pricking up their ears interestedly. The truth was, they liked princesses, and they all hoped they might hear something more definite about this one, and drew nearer Sara accordingly.

Lavinia could only invent one remark, and it fell rather flat.

"Dear me," she said, "I hope, when you ascend the throne, you won't forget us!"
