"Perhaps," Dagobert said, "it is the punishment inflicted on us by that mother from whose care and discipline we have run away. I mean, that in that golden age when our race was living in the most perfect union with all nature, no dread or terror disturbed us, for the simple reason that in the profound peace and perfect harmony of all created things, there was nothing hostile that could cause us any such emotion. I was mentioning strange spirit-sounds; but why is it that all the real _nature_-tones--of whose origin and causes we can give the most complete account--sound to us like the most piercing sorrow, and fill our hearts with the profoundest dread? The most remarkable of those nature-tones is the air-music, or, as it is called, the 'devil-voice,' heard in Ceylon and the neighbouring countries, spoken of by Schubert in his 'Glances at the Night-side of Natural Science.' This nature-tone is heard on calm and bright nights, sounding like the wail of some human creature lamenting in the deepest distress. It seems to come sometimes from the most remote distance, and then again to be quite close at hand. It affects the human intelligence so powerfully that the most self-controlled cannot help feeling the deepest terror when they hear it." "Yes," said Moritz, "it is so. I have never been in Ceylon, certainly, or in any of the neighbouring countries; but I have heard that terrible nature-sound; and not only I, but every one else who heard it, felt just that precise effect which Dagobert alludes to." "I should be extremely obliged to you," said Dagobert, "and you would probably convince Madame von G. also, if you would not mind telling us what happened."
