Mysterious Zones of Silence.

A meteorologist of Zurish, Dr. A. de Quervan, directs attention to a newtheory which he calls a zone of silence. He says that strong noises like explosions or the sound of cannons, while heard in a normal way in their immediate neighborhood, afenot heard in a distant zone even when most intense. It Is now known as a historical fact that Frederick the Great on August 17, 1760, won the battle of Liegnitz because the Austrian generals Dann and Lasen asserted that they had not heard the sound of cannons. It was supposed at that time that the statement of the Austrian commanders was an untruth, but it is now believed that a zone of silence existed. Similar phenomena have been observed ly. In 1908, when the Jungfrau railroad was being built in Switzerland, a fearful detonation took place, caused by the explosion of 25,000 kilograms of dynamite. The noise was heard at a distance of 30 kilometers, but not at 140 kilometers. Strange to say, howBver, the noise was heard 50 kilometers from the last named zone.
