Katherine looked startled. "No. And I've lost something else--my great-grandmother's pearl necklace. Mother said I shouldn't take it to school with me, but I was sure I would be careful with it. And I was, girls, I really was. It stayed always in the bottom of my trunk, in its velvet case. I don't believe any of you ever knew about it. I haven't even taken it out since I left home. But yesterday I thought I would make sure that it was safe under everything in the trunk. And I looked, and it was not there. I cannot understand it, but it is true. Mother was right, as usual. I don't know how I am ever to tell her."
