Hatfield's Secret Method of Making Rain

Hatfield first tried his method from an old windmill tower on his father's ranch on Bonsell, near San Diego. He never patented it for fear that rain producers would spring up like mushrooms all over the country. Hatfield used chemical combinations working in harmony with the very law that makes rain and a natural sense. In the daytime, solar heat speeded vaporization, and at night, combustion was added.
