By her skill in jumping it was plain to see that it was not the first time she had accomplished this. Rita now looked triumphantly around as if to say: "Now I am once more seated in my strong castle where no harm can reach me!"

When Rita found the big paper was no longer between her and her Papa she threw her arms around his neck and said, "Good-morning," with great affection. Meanwhile, her sister Ella was standing perfectly still beside her Papa's chair, waiting for his morning greeting. Then he kissed his older little daughter also, and she sat down quietly at the table.
