M. van der Broeck elsewhere refers to "similar noises heard on Dartmoor, and in some parts of Scotland." Readers of Blackmore's story of "Lorna Doone" will remember, among other valuable observations of out-door life, his accounts of "the hollow moaning sound" during the intense cold of the winter, of which he gives so graphic an account. It was "ever present in the air, morning, noon, and night time, and especially at night, whether any wind was stirring or whether it were a perfect calm" (Chap. xlvi.).
Another correspondent in _Nature_ refers to remarkable noises among the hills of Cheshire: "When the wind is easterly, and nearly calm on the flats, a hollow moaning sound is heard, popularly termed the Soughing of the Wind, which Sir Walter Scott, in his glossary to 'Guy Mannering,' interprets as a hollow blast or whisper."
Another writer quotes experiences in East Anglia, tending to show that such sounds may be reports arising from the process of "faulting" going on, on a small scale, at a great depth, and not of sufficient intensity to produce a perceptible vibration at the earth's surface.
It would seem that in districts such as Comrie in Perthshire, East Hadden in Connecticut, Pignerol in Piedmont, Meleda in the Adriatic, &c., sounds without shocks are common during intervals, which may last for several years. Remarkable sounds, not apparently accounted for, are reported to proceed from Lough Neagh in Ireland.
