"All right! Just wait and see!"

It was perfectly unreasonable of Aldred to feel aggrieved because Miss Webb had asserted her authority; but she chose to consider that she had been unfairly treated, and that she was justified in nursing her wrath. She cast about for some means of turning the tables and annoying the mistress, but it was rather difficult to hit upon anything safe; she had no wish to get herself into serious trouble, and knew that any open defiance would be reported at head-quarters.

"It must be something she can't fix specially upon me," reflected Aldred; "something that any of us might have done. The whole class dislikes her, so I shall really be acting champion for the rest; only, I think I won't tell them anything about it beforehand; it shall come as a surprise."

After serious cogitation, she decided to chalk Miss Webb's chair, so that her black dress should show a white impression of the cane seat and back.

"She won't know," thought the girl, "and of course we shall none of us tell her, and she'll be going about the school looking such a guy! She'll wonder why everybody is smiling."

By nine o'clock next morning Aldred had her unpleasant surprise already prepared. She had managed to slip into the classroom before breakfast, and to chalk the chair thoroughly; and she now sat in her place, laughing in anticipation. Miss Webb was punctual. She entered in her usual rather flurried, undignified manner, and was about to close the door after her, when she suddenly opened it wide again to admit—Miss Drummond and Mabel! This was a totally unlooked-for event. Aldred had not known that Mabel was returning to class that day, as it had been reported that she was to remain in hospital for the rest of the week; and she certainly did not expect the head mistress. Mabel walked quietly to her own desk, and Miss Drummond (alas for Aldred!) sank straight down on the chair that Miss Webb at once politely offered her.

"I have come this morning, girls, to say a few words to you," began the Principal. "I have examined your marks for the last three weeks, and also the list of the viva voce examination that you had yesterday. I wish to tell you that I am extremely dissatisfied. I have never seen such a low average from the Fourth Form, and I am sure that you are none of you doing your best. I cannot possibly allow such a state of affairs to continue; it is a disgrace to the school! I am greatly disappointed, as I had hoped for better things from you. It has been a very hard task for Miss Webb, who kindly came to help us in an emergency, to take up another teacher's work at so short a notice, and I believed that you would have realized her difficulties, and have made an effort to help her in every way in your power. Instead of this, you appear to have taken advantage of Miss Bardsley's absence to neglect your work. As I cannot trust you to do your preparation adequately and thoroughly in your own classroom, I am going to make a new arrangement, and you will bring your books each evening into the lecture-hall, and sit with the Sixth Form, when I can myself see that you are not wasting your time. I have also asked Miss Webb to bring me the register at the end of each morning. I shall check your marks, and any girl who, as I consider, has fallen below her usual standard, will stay indoors during the afternoon, to learn the lessons in which she has failed."

If Miss Drummond looked grave, the Form looked utterly crestfallen and ashamed. The girls sat perfectly still, gazing at their desks, for nobody dared to meet the Principal's eyes. As for Aldred, she was filled with blank dismay. It was bad enough to be scolded for ill-prepared work, but what was going to happen when Miss Drummond got up from her chair? That she hardly dared to guess, and she would have given everything she possessed if she could have recalled her silly act. She was kept for some time in suspense, as the head mistress called for their exercise-books, and insisted upon examining them all minutely, and asking various searching and awkward questions as to the reason for so many mistakes and misspelt words, and such bad writing. The Fourth Form had never endured such an unpleasant quarter of an hour, and Aldred, between her present discomfiture and her apprehension of what was to come, felt as if she were passing out of the frying-pan into the fire.

The dreadful moment arrived at last. Miss Drummond handed the exercise-books back to the monitress, and rose up. Aldred's trick had answered only too well: the pattern of the cane seat was imprinted most plainly upon the head mistress's handsome dress. As she turned for an instant to consult the time-table, everybody noticed it, and a universal gasp of horror passed round the room. Miss Webb blushed hotly, and hesitated as if in doubt what to do; then, apparently plucking up her courage, she nervously informed the unconscious Principal of the state of affairs. Miss Drummond looked keenly first at the chair and then at the girls.

"Who is responsible for this?" she asked, in a constrained voice.
