Dyrenforth commandeered a section of Texas prairie and began a three-pronged assault on the great blue yonder. First his men fired mortars at the clouds. Spaced between them were kites carrying bundles of dynamite, which were detonated via an electrical charge. Behind them floated a line of explosive hydrogen balloons, which had a tendency to break free and drift wildly across the plains. After blazing away at the sky for some time, Dyrenforth decided to up the noise level by packing local prairie dog holes full of dynamite. Because if you're going to pick a fight with Mother Nature, why half-ass it?
Somehow, the plan to gun down the rain failed to work, although that didn't stop Dyrenforth from claiming that it totally did. He was foiled by the only real meteorologist on the expedition, who published a scathing report in Nature. Although the real tragedy was that the 19th century's greatest pyrotechnics show was witnessed mostly by a few baffled cows and some shell-shocked prairie dogs. But if anyone out there is writing a western, remember that it's historically accurate to have your heroes stumble across a bunch of civil servants flying huge explosive kites in attempt to bomb the sky.
