She thought the loss warranted writing a note to Margy, though the teacher severely discouraged this practice.

“Lost your pin!” Margy’s lips echoed silently, when she had read the note. “How perfectly awful! Where?”

Polly shook her head to show she did not know. But she was afraid she had lost it in the midst of the snowball battle, and the prospects of recovering it were exceedingly dim.

Now Margy had sharp eyes when she chose to use them, and she could be counted on to be interested in what went on outside her books. While poor Polly was trying to forget her troubles in the writing lesson, Margy’s dark eyes were roving over the room in search of amusement.

Carrie Pepper sat near her, over two aisles, and she, too, was apparently little interested in the lesson. When the teacher’s back was turned, Carrie swiftly passed something to Mattie Helms, who sat behind her.

“I wonder what she has,” thought Margy, idly.

Mattie’s head bent over something as she examined it, then she dropped her pencil. It rolled under the desks and Mattie stooped to get it. As she straightened up, she dropped the something lightly on Joe Anderson’s writing book.

Margy could not see, from where she sat, what the something was, but, like a flash, she guessed.

“Polly’s pin!” She almost said the words aloud. “Polly’s pin! Carrie was right behind her coming up the stairs this noon. I’ll bet she found the pin, and she’s so mean, she won’t give it back.”

Margy hastily took her pen and attacked the writing lesson. She wanted to think. Apparently absorbed in the work before her, she was planning to find out whether Carrie had really found the missing pin.
