In 1915, Charles Mallory Hatfield was traveling the country “coaxing” rain out of the skies in even the most arid regions. He was so good at it, city-council members in San Diego offered him $10,000 if he could fill their reservoirs and end their drought. What happened next was both success and tragedy—it rained so much it flooded. How did he do it? The Rain Wizard, by Larry Dane Brimner doesn’t quite say, but reviewer Ilene Cooper makes a theory of her own: “budding scientists may well take this as a challenge to find out more.” The trailer showcases the book’s many historical photos—take a look!
