The little girl wanted to assure Nanna there was no good reason to assume that mental decay had set in, but she did not do this at once, and afterwards it seemed too late. So nurse was allowed to chat on, and tell her very best story about the time when she was a child, and a good one at that, and when the clock, having been compelled to go over the ground twice, again gave the time as ten to seven, nurse said, "Now my dearie!" Upstairs, the little girl devoted a few minutes to instructing her dolly in the art of going off nicely to bye-byes. She was left alone, with just a mere star of gas-light for company shining above the dressing-table, and at the moment when she was about to go to sleep conscience woke up. Conscience became wide-awake. Conscience insisted upon talking, and the little girl had to listen. She was aware it is useless to cry when one is by oneself with nobody looking on; not only useless but wasteful, because you may want those tears on more important and more public occasions. So the little girl did not weep, but, oh! she felt troubled. She did feel troubled. "A silly, stupid world!" she cried aloud. "It ought--it ought to be changed. I'd very much love it to be altogether different." A knock at her door, and she answered, "Please come in, Nanna!" Not nurse. Certainly the tall lady with diamonds sparkling in her hair, and a white chiffon kind of costume, and a long silver stick in the right hand, was as unlike nurse as any one could be. The little girl said, "Oh, I beg pardon!" in her politest manner. "It is for me to beg yours," answered the tall lady with severity. "I am exceedingly sorry to disturb you." "Pray don't mention it." "I wish to mention it," insisted the lady. "I claim the right to mention it. I decline to allow any one to dictate to me what I shall or what I shall not mention. I am a good fairy." The little girl opened her mouth with surprise. "A good fairy, and I am here to do you a favour. When a good fairy wishes to do a favour, it is only necessary for a wish to be expressed, and----" [Illustration: "Bless my soul!" cried nurse] "Thank you," said the child nervously, "but really I would so much rather you did not take the trouble." "The trouble," replied the good fairy, striking the floor with her silver stick in an impatient way, "is no concern of yours. You mustn't haggle." "I don't know what that means," declared the other earnestly, "and if I did, I wouldn't do it, ma'am, I wouldn't really. Good evening, and, of course, thank you ever so much for calling." "Dress!" ordered the good fairy.
