Congress Appropriates Funds to Test Concussion Theory of Rain
(p. 190) the first century A.D., when the Greek moralist Plutarch came up with the notion that rain followed military battles. Napoleon believed as much and fired cannons and guns at the sky to muddy up the ground between him and his attackers. Civil War veterans who wallowed in cold slop believed that ceaseless, close-range artillery fire had opened up the skies. In the late 1890s, as the first nesters started to dig their toeholds on the dry side of the one hundredth meridian, Congress had appropriated money to test the concussion theory in Texas. The tests were done by a man named Dyrenforth. He tried mightily, with government auditors looking over (p. 191) his shoulder, but Dyrenforth could not force a drop from the hot skies of Texas. From then on, he was called "Dry-Henceforth."
Government-sponsored failure didn't stop others from trying. A man who called himself "the moisture accelerator," Charles M. Hatfield, roamed the plains around the turn of the century. A Colonel Sanders of rainmaking, Hatfield had a secret mixture of ingredients that could be sent to the sky by machine. In the age before the widespread use of the telephone, it was hard to catch up with the moisture accelerator after he had fleeced a town and moved on.
