Discovery of a Place Where No Static Could Be Heard in August

The origin of natural static near mountain peaks is described and compared, in its mode of production and character, with that produced by smoke precipitators. Some mountains are believed to be soucres of static, while others act as absorbing shields to signal and static. On these bases, a certain point near Ketchikan, Alaska, was found where static was not heard in midsummer, while signals were received from some directions but not from others.
