“One rainy winter evening, as I was alone in my room,” says an American gentleman, “I took up my flute and began to play. In a few minutes my attention was directed to a mouse that I saw creeping from a hole, and coming toward the chair in which I was sitting. I stopped playing, and it ran quickly back to its hole. I began again shortly afterward, and was much surprised to see it reappear, and take its old position. The actions of the little animal were truly amusing. It lay down on the floor, shut its eyes, and seemed delighted, but the minute I stopped my playing, it instantly disappeared again. This experiment I often repeated with the same result. I also noted that the mouse was differently affected, as the music varied from the slow and sad to the brisk or lively. It finally went away, and all my art could not coax it to return.”
