"If she does we'll go on strike, and say we can't do the paper. I can't possibly calculate where two people will meet each other on the road, if they start from different points at different times. I should think it depends how often they sit down to rest, or stop to talk to friends on the way, or how fast they want to get to the end of their journey," said Avis.

"There was that dreadful problem about dividing oranges among schoolboys," continued Winnie. "If I know anything of boys, they'd have thrown them down and scrambled for them; it would have been a far easier way of settling it. I always feel my head ache after trying to reckon those absurd things."

Every fortnight the class had a small examination in arithmetic, which was almost as solemn an affair as those held at the end of the term. Among other rules, Miss Rowe had decided that the girls, instead of remaining at their own desks, should all change places and sit according to her directions, her object being to separate those kindred spirits who, she considered, might be tempted to whisper or otherwise communicate with each other if left in too close proximity. By this new arrangement Patty found herself seated next to Muriel. Enid was at the desk behind, and it was therefore impossible to exchange even a smile with her without deliberately turning round. For some time the class worked away steadily and in silence. Occasionally a girl would so far forget herself as to count aloud, but a glare from Miss Rowe would instantly recall her to a sense of the enormity of such a misdeed. Naughty Enid managed to draw a cat on the margin of her blotting paper, and held it up for an admiring comrade to see; and Beatrice Wynne gave a terrific yawn, for which she was told to lose an order mark. Patty had been struggling for a long time with a difficult sum in compound proportion, and having just finished it, paused for a moment to take a rest. She presently became aware that Muriel, with lips pursed up as if forming the word "Hush!" was trying to attract her attention, and that Muriel's hand was secretly passing her a small note under cover of the desk. She opened it at once. It ran thus:

"How do you state Question 5? Ought the answer to be in bales of silk or days?"

Now Patty had only been a fortnight at The Priory; she knew little of the rules of a large school, and this was the first real class examination in which she had ever taken part. At Miss Dawson's school she was accustomed to help any girl who applied to her for aid, and indeed had often taught the younger ones how to work new rules, with the full sanction and approval of the mistress. She did not yet understand that an examination was a test of individual knowledge, and that no assistance must be either asked for or given. The only thing she realized was that Muriel wanted to know something which it was in her power to explain. She moved, therefore, as close to her cousin as she could, and, leaning over towards the latter's desk, took up her paper of questions.

"I've just finished it myself, and it comes out nicely in bales of silk," she whispered.

"Patty Hirst!" cried Miss Rowe, springing up in horrified indignation. "Do you know that any girl detected in the act of copying must instantly leave the examination?"

"Please, Miss Rowe, I wasn't copying," returned Patty, with some surprise.

"But I saw you deliberately look at your neighbour's paper."

"I wanted to show her something," explained Patty.
