Miss Webb, to their surprise, did neither. Her line of conduct was totally unexpected. She announced, quite calmly and briefly:

"I find that a mistake was made this morning in the time, and that you lost twenty minutes of your examination. By noting your marks during the ten minutes we spent on Roman history, I have been able to calculate the general average that you would have received during the entire half-hour, and, as a result, I have added one right answer and eight misses to each of your names on the register, and ten extra misses to Aldred Laurence, in lieu of forfeits."

The girls groaned inwardly, but they knew they were checkmated. If they dared to remonstrate, Miss Webb would probably expose the entire episode to Miss Drummond, so they wisely said nothing.

They certainly well deserved all they had received, particularly Aldred, who for once had been a little too clever. Her additional bad marks placed her at the bottom of the list, a position she had never occupied since she entered the school. She was very irate in consequence.

"I detest Miss Webb!" she declared. "It was a disgustingly mean way of her to take revenge on us. How could she tell I had altered the clock?"

"Any idiot could have guessed that!" returned Dora. "It was perfectly simple to put two and two together; we all knew."

"Well, I think it was nasty of her, all the same, and I mean to pay her out."

"If you can."

"Oh, I'll manage it somehow!"

"Better not boast too soon."
