Yesterday I had prepared for him his Au Bord d'une Source. I was nervous and played badly. He was not to be put out, however, but acted as if he thought I had played charmingly, and then he sat down and played the whole piece himself, oh, so exquisitely! It made me feel like a wood-chopper. The notes just seemed to ripple off his fingers' ends with scarce any perceptible motion. As he neared the close I remarked that that funny little expression came over his face which he always has when he means to surprise you, and he suddenly took an unexpected chord and extemporized a poetical little end, quite different from the written one.— Do you wonder that people go distracted over him?
