"It's you that ought to tell her. It was all your fault, you'd no right to help Alice to cheat."
"I know that's true. But it makes it all the more impossible for me to tell on her."
Just then Alice came in:
"Oh, Margaret!" she cried.
Then she saw Mabel and stopped.
"Are you going to tell Miss Vinton you cheated?" said Mabel, going up to her with flaming eyes.
"Margaret, did you tell?" said Alice.
"I saw you!" said Mabel, "I sat just behind and saw you! You're not going to try to keep my prize, are you?"
"No, of course not," said Alice, "I never thought of getting the prize. I only wanted to write a decent paper and not have Miss Vinton pitching into me as usual. You're welcome to the prize, if that will do."
Mabel said nothing.
