“Oh, Miss Olaine! there must be some mistake there. I know Dorothy so well,” said Mrs. Pangborn, gravely. “The two are always together; but I am sure that whatever Dorothy told you was true. And Tavia, too, for that matter.”

“I am positive they were endeavoring to mislead me. And they would not tell who had helped them, or who else was in the plot to put those pigs in this house——”

“Miss Olaine!” gasped Mrs. Pangborn, suddenly. “That is something I forgot to speak of when I went away in such a hurry the day after you came to Glenwood.”

“What is that?” asked the surprised assistant.

“I never ask one of my girls to tell on another. They are all on honor, here. I do not expect any girl to play the spy. Indeed, I punish severely only those who show such a tendency. You were wrong to expect either of those girls to give any information which might lead to trouble for their schoolmates. Whereas, if they say nobody else was aware of the prank——”

“Miss Travers refuses to admit that she had any help at all.”

“If she says it is her own performance, you may believe it is so.”

“Oh, I do not believe in giving such latitude to mere school girls,” declared Miss Olaine, and now she was quite heated again.

Mrs. Pangborn looked at her seriously. “You have much to learn yet, I fear, Miss Olaine,” she said, quietly. “Reports of your erudition and management of studies in a great public school urged me to engage you as my assistant; but you must be guided by me in the management of my girls—that is sure.

“You might have known that shutting a girl like Tavia Travers into that little room would be no real punishment. She would merely put on her thinking cap and endeavor to bring about something that would make you look the more ridiculous.”
