A large screen was placed on one side of the platform, and a grand piano nearly filled the other side, leaving a central space for the performers. At first Hubert had wondered why the screen was there. Now he saw its use. Madame della Scala seated herself in a chair behind it, with her face to the singers--evidently under the delusion that her figure was completely hidden from the audience, and that she could, unseen, direct, stimulate, or reprove the singers by movement of head, hands, handkerchief, and fan. The manoeuvre would have been successful enough, but for the fact that the back of the platform was entirely filled with a sheet of looking-glass, and that in this mirror her gestures and facial contortions were all distinctly visible to the greater number of the listeners. Hubert found great satisfaction in watching the different expressions of her countenance; he told himself that Madame's face was the most interesting part of the performance. How sweetly she smiled at her favorite pupils from the shadow of the screen! How she nodded her head and beat time with her fingers to the songs they sang! How, in moments of uncontrollable excitement, she waved her hands and swayed her body and gesticulated with her fan! It was a comedy in dumb show. And, as each girl-singer, after performing her part and curtseying to the audience, passed her teacher on the way to the artists' room, Madame seized her impulsively by both hands, and drew her down to impress a kiss of satisfaction on the performer's forehead. The woman's old charm as an actress, the Southern grace and excitability and warmth, were never more evident than when reflected in Madame's movements behind the screen that afternoon, and visible to the audience--did she know it after all?--only in a looking-glass.
