Miss Crossland glared at her through her eyeglasses.

'If you are so careless as to be late, Margaret Vaughan,' she remarked, 'the least you can do is to come in quietly without disturbing the class.'

Rather crestfallen, Peggy threaded her way to her place, and took out her arithmetic books.

'Which sum are you doing?' she whispered to her desk-mate, Emily Thompson; but Emily judiciously pretended not to hear, for she did not wish to waste valuable time in giving Peggy information. She was rather a pretty girl. Her light flaxen hair and pale, fair complexion gave her a smooth, shining appearance, and somehow Peggy always thought her manners were smooth and shining too, for she had a way of wriggling out of any little difficulty and unpleasantness, so that the blame rested upon other people, and was always ready to take a mean advantage, or play some of those little underhand tricks which schoolgirls know only too well.

Peggy's frank, downright nature held Emily in much contempt, and, as she made no effort to conceal her opinion, the dislike was mutual, and a kind of undeclared war existed between the two. It was unfortunate for Peggy that the third form classroom was furnished with double desks, for as Miss Crossland would permit no changing of places, she was obliged to sit by her enemy for the rest of the term, to their equal discomfort and annoyance.

The lesson dragged on wearily for awhile, till they were disturbed by a tap at the door, and a small girl from one of the lower classes entered, full of importance at her errand.

'If you please, Miss Crossland,' she piped, 'Miss Martin would like to speak to you for a moment in the library.'

Miss Crossland looked annoyed; she disliked being interrupted in her classes, but the head-mistress's request could not be disobeyed.

'Very well, Gertrude,' she replied coldly; then, turning to her class: 'Girls, I must leave you for a few minutes. I trust you to continue your arithmetic in silence during my absence. Not a word must be spoken while I am out of the room.'

For so long indeed as her footsteps echoed in the passage her pupils obeyed her order, but the moment she might reasonably be believed to be out of earshot a low murmur began among the little heads bent so discreetly over the arithmetic books. No one attempted to do any work; sweets and apples appeared mysteriously from within desks, and surreptitious bites were offered to appreciative neighbours. One daring spirit even mounted the platform, and waved the pointer in supposed imitation of Miss Crossland's majestic style.
