Text: "The principle is this: a ray of great ionizing power is used to give to the atmosphere great power of conduction. A high tension current of 10,000,000 to 12,000,000 volts is then passed along this ray to the upper strata of the air, which strata can be broken down very readily and will conduct electricity very well."
