Mary and I were put into Algebra at the same time, and to our joy Miss Cox was to teach us. Mary had found out Miss Cox, too. Tweedles and I had religiously refrained from telling any of the girls about her mad revel on the day of our arrival, but we had tried to make them understand what a very good old girl she was if you could just find her out; and our attitude toward her was having its effect on the whole school. Miss Cox, realizing that she was really liked and understood, had a change of expression as well as heart. Her sad, crooked face was now a happy, crooked face and she no longer saved her jokes for Tweedles and me, but got them off indiscriminately, and very good jokes they were, too. The classes in voice culture became more popular, and more and more girls wrote home begging to be allowed to "take singing."
